She said her family did not immigrate to the United States to become a part of India and China and other authoritarian countries whose citizens are now making the majorities of California's population, and speculated that the Board member are all collaborating and receiving kickbacks; Chair Mitchoff clarified for listeners that the public speaker on the Vision Zero item alleged that a Lafayette individual might have a conflict of interest, not a Board member, and that every year all elected officials are required the file a Statement of Economic Interest (aka Form 700) that lists all investments, land ownership, gifts and loans, which is available to the public Caller 6770, in agreement with previous caller on concerns of independent judgment feels that the Board does not respresent it's constituents and is presented with and follows instruction to accept the issues without question. He further commented on the presentation last week regarding the charitable donation of $83,000 from County employees to the Contra Costa/Solano Food Bank in its annual food drive, noting that equals less than $9.50 per employee and suggests that when the Board criticizes the John Muir and Kaiser hospital systems (for not continuing contribution to Contra Costa CARES) that they look to how their own employees spend their money; Addy would like to bring awareness to the Martin vs. Boise 9th Circuit ruling which provides that unhoused individuals should not be removed in sweeps unless shelter is available for them to go to. She said an illegal sweep of approximately 20 unhoused persons took place at Market Street/Willow Pass underpass (Highway 242) in Concord as well as other locations.

BACKGROUND: PROJECT SUMMARY The project, known as the “Oak Road Townhouse Condominium Project” involves the development of 125 townhouse condominium units within 19 three-story buildings (some of which will have rooftop decks) on an approximately 5.94-acre site located on Jones Road and Oak Road in the unincorporated Walnut Creek area of the County. The project includes a preliminary and final development plan to develop the site with the 125 townhouse units, along with complete site improvements, a rezone of the project site to a Planned Unit District (P-1), and a subdivision of the property into 19 residential common lots and 11 private roadway lots (to be owned and maintained by the future homeowners association). In order to develop the site, demolition of the all of the existing buildings and structures of the former Palmer School is required. Approximately 278 on-site parking spaces will be provided, including 34 bicycle spaces. The project includes the removal of approximately 74 trees, relocation of one tree, and work within the dripline of approximately six trees. There will be grading of approximately 9,300 cubic yards of cut and approximately 8,700 cubic yards of fill. GENERAL INFORMATION General Plan: The project site has a Multiple-Family Residential- High Density (MH) General Plan land use designation. 1. Zoning: The project site is located in a Multiple-Family Residential (M-17 and M-29) and Single-Family Residential (R-15) Zoning Districts. 2. California Environmental Quality Act (CEQA) Compliance: The Department of Conservation and Development, Community Development Division (CDD) determined that an EIR was required for the project and distributed a Notice of Preparation (NOP) on April 28, 2021. The Draft EIR (DEIR) was released for public review on October 21, 2021 and was available for public review and comment for a period of 45 days, through December 6, 2021. 3. The Final EIR was published and made available for public review on January 12, 2022. The EIR identifies potentially significant environmental impacts that would occur if the project were implemented and identifies mitigation measures that would reduce potentially significant impacts to less than significant levels. The recommended mitigation measures are included within the Mitigation Monitoring and Reporting Plan, which describes the timing and responsible agency for monitoring compliance with all mitigation measures. The mitigation measures have also been incorporated into the recommended conditions of approval. SITE/AREA DESCRIPTION Surrounding Land Uses: The project site is surrounded to the east by the City of Walnut Creek, to the north by unincorporated County, to the west by I-680 and the City of Walnut Creek beyond it, and south by unincorporated County, the Contra Costa Canal, and the City of Walnut Creek. The project site is bound by residential uses to the north and south, by Oak Road to the east with residential uses across Oak Road, and by Jones Road to the west and north. Office uses are located north of Jones Road, while I-680 is located directly 180 feet west of Jones Road. The Contra Costa Canal is approximately 470 feet south of the project site. The nearest Bay Area Rapid Transit (BART) station (Pleasant Hill/Contra Costa Centre Station) is located approximately 0.25-mile northeast of the site. Site Description: The 5.94-acre project site is relatively flat (approximately 90 to 95 feet above mean sea level), with a topographic gradient that slopes gently to the northeast. The project site consists of eight parcels and is developed with structures associated with the former Palmer School for Boys and Girls, a private K-8 school for approximately 400 students that operated from 1939 until its closure in June 2020. The former school consists of 14 vacant buildings as well as associated structures, including classrooms, an auditorium, a front office, a paved courtyard, a grass field, tennis courts, basketball courts, playgrounds, a swimming pool, parking lots and planters. Multiple storage sheds are present on the school site. A landscaped area is located behind the classrooms along the southern boundary of the property and includes planter boxes, storm drain lines, power boxes, and a partially uncovered pipe that appears to be related to storm drainage. In the southeast corner of the property is a 2-story auditorium formerly used as a storage area, containing a kitchen, stage, water heater, and empty storage rooms on the second floor. Several of the existing structures in the northern portion of the project site have been associated with residential uses, including those at 2771, 2747, and 2751 Oak Road. To the east of these buildings is an unpaved lot and a paved driveway. These units are occupied by the property owners’ family members who provide caretaker security services for the property and existing improvements. These units will be vacated in conjunction with the applicant’s acquisition of the property. All other buildings are vacant. PROJECT DESCRIPTION The proposed project includes rezoning of the project site from Multiple-Family Residential (M-17 and M-29) and Single-Family Residential (R-15) Zoning Districts to a Planned Unit District (P-1). The proposed project also includes a preliminary and final development plan to allow the demolition of all existing improvements currently present on-site, including buildings, foundations, asphalt, concrete, fence poles, and landscaping to allow the construction of 19 new three-story buildings (some of which will have rooftop decks) containing 125 condominium units. The approval of a vesting tentative map to reconfigure the current eight parcels into 19 new residential (common) lots and 11 private roadway lots was approved by the County Planning Commission on January 26, 2022. The major project component includes the following: approximately 237,697 square feet of new residential living area (293,507 total gross building square feet), approximately 92,120 square feet of landscaped area, the removal of approximately 74 trees, relocation of one tree, and work within the dripline of approximately six trees, 278 on-site parking spaces and 34 bicycles spaces, internal street, courts, walkways, and drainage improvements, and construction of off-site improvements that include frontage sidewalk, driveway curb/gutter improvements (including retaining existing on-street parking) and street tree planting. The project will involve grading of approximately 9,300 cubic yards of cut and approximately 8,700 cubic yards of fill. Residential Uses The proposed 19 buildings will be approximately 293,507 gross square feet, covering approximately 127,768 square feet (or 50 percent) of the 5.94-acre site. The units will consist of three or four bedrooms and two to three and a half baths. Most of the units will have a two-car garage, except for six units that will have a one-car garage and a parking space designated for each of the six units. The units will have a balcony and private fenced yard. Units along Oak Road will have a roof deck that faces into the development, away from Oak Road. The unit breakdown for the townhouse condominiums is provided on the table below. Proposed Dwelling Unit Summary Number of bedrooms/bathrooms Unit Net Sq. Ft.Garage Sq. Ft.Number of Units 3 bedroom/3 bath 1,362 436 14 3 bedroom/3 bath 1,362 436 13 3 bedroom/3 bath 1,430 436 1 4 bedroom/2 bath 1,523 289 6 3 bedroom/3.5 bath 1,844 478 15 3 bedroom/3.5 bath 1,891 478 5 4 bedroom/3.5 bath 2,038 462 28 4 bedroom/3.5 bath 2,098 462 5 4 bedroom/3.5 bath 2,250 449 32 4 bedroom/3.5 bath 2,281 449 6 Total Units 125 Ancillary Facilities and Recreation Uses Amenities to serve residents will also be provided. The project proposes a total of approximately 92,120 square feet of landscaped area (25 percent of the site), including a central open space area, paseo/walkways, and a dog park. The outdoor recreation area includes a turf area between Buildings P, Q, R, and S, which also includes benches and tables between Buildings Q and S. There is also another area with benches and tables located between Buildings D and E. The dog park will be located on the northwestern corner of the project site, directly north of Building C. Circulation and Access Jones Road and Oak Road border the project site. Jones Road is a two-lane public street that runs north/south along the site’s western boundary. Oak Road is a four-lane public street that runs north/south along the site’s eastern boundary. Primary access to the site would be from two driveways: one along Jones Road and one along Oak Road. Two parking slots between Buildings D and E would be designated as ADA parking. Fire access routes, providing 25-foot inside turning radii and 45-foot outside turning radii, would be provided through the internal loop roads around the central buildings (Buildings P, Q, R, and S). Emergency vehicle access would be provided via the two proposed driveways on Jones Road and Oak Road. Building Design and Height The proposed project includes 19 three-story buildings, including three buildings on Oak Road with roof decks. Building height will range from 37 feet to a maximum of 43 feet; buildings with a roof-top deck may extend up to 45 feet in height. The buildings will be setback 15 feet from Jones Road and 10 feet from Oak Road. Exterior features of the buildings would include board and batten sidings, horizontal fiber cement lap siding, exterior stucco, architectural composition roofing shingles, metal awnings, vinyl windows, and painted metal railing. The exterior color palate would be comprised of whites and grays. Lighting and Signage A monument sign is proposed at the entrance from Oak Road. The monument sign would include metal letters atop a 4-foot wall with a stone veneer finish. An 11-foot-tall structure, with pitched roof and siding matching the general architecture of the residential buildings, would be installed adjoining this wall, and a plaque with the Oak Road logo would be installed on this structure. Proposed lighting would include exterior lighting for the buildings and pole-mounted lighting throughout the parking areas. Specifically, exterior lighting would include four new streetlights along the Oak Road frontage, matching existing streetlights along this street; eight private street pole lights near the two project entrances and along the public streets and sidewalks, approximately 20 feet tall with shielding to direct lighting downward; forty 3.5-foot bollard lights strategically located throughout the site along pathways, common open space and paseos; and 125 wall pack lights above the garages for each home, to illuminate the driveways. Additionally, each of the 125 residential units would have a front porch light. INCLUSIONARY HOUSING AGREEMENT In accordance with the County's Inclusionary Housing Ordinance and as required in conditions of approval numbers 49-58 for the project, the applicant/developer is required to construct and sell 10 on-site units affordable to moderate income households and to pay an in-lieu fee in the amount of $387,753.52. The applicant/developer proposes to comply with this requirement by complying with the terms of the attached Inclusionary Housing Developer Agreement. Staff has assisted in the development of the agreement and recommends that the Board approve this agreement. ENVIRONMENTAL REVIEW The Department of Conservation and Development (DCD) determined that an Environmental Impact Report (EIR) was required for the project and distributed a Notice of Preparation (NOP) on April 28, 2021. The Draft EIR (DEIR) was released for public review on October 21, 2021 and was available for public review and comment for a period of 45 days, through December 6, 2021. The responses to the comments received during the DEIR comment period are addressed in the Final EIR (FEIR). The FEIR and the mitigation monitoring and reporting program (MMRP) were made available to the public on January 12, 2022. Summary of Environmental Impacts The DEIR prepared for the project identified the environmental impacts which would occur if the project was implemented and proposed mitigation measures that would reduce impacts to a less than significant level. Potential significant impacts mitigated to less than significant were identified in the following areas: Aesthetics, Air Quality, Biological Resources, Cultural Resources and Tribal Cultural Resources, Geology and Soils, Hazards and Hazardous Materials, Hydrology and Water Quality, Noise, and Recreation and are summarized below: Aesthetics: Discussed in detail in DEIR Section 3.1. The project could create a new source of substantial light or glare. All potentially significant impacts can be mitigated to a less than significant level (See Mitigation Measure AES-4). Air Quality: Discussed in detail in DEIR Section 3.2. The project could result in a cumulatively considerable net increase of any criteria pollutant for which the region is in non-attainment under an applicable federal or State ambient air quality standard and would expose sensitive receptors to substantial pollutant concentrations. All potentially significant impacts can be mitigated to less-than-significant levels (See Mitigation Measures AIR-2 and Air-3). Biological Resources: Discussed in detail in DEIR Section 3.3 and in the Final EIR. The construction of the project could have a substantial adverse effect on sensitive or special status species located within the project site, and on trees protected by the County’s Tree Protection Ordinance. All potentially significant impacts can be mitigated to less-than-significant levels (See Mitigation Measures BIO-1a, 1b, 5a, and 5b). Cultural Resources and Tribal Cultural Resources: Discussed in detail in DEIR Section 3.4. Implementation of the project could potentially cause a substantial adverse change in the significance of a historical resource and archaeological resource as defined in Section 15064.5, cause a substantial adverse change in the significance of a Tribal Cultural Resource that is listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1 (k), cause a substantial adverse change in the significance of a Tribal Cultural Resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1, and the project could disturb human remains. All potentially significant impacts can be mitigated to less-than-significant levels (See Mitigation Measure CUL-1 and CUL-3). Geology and Soils: Discussed in detail in DEIR Section 3.6. The project could directly or indirectly cause potential substantial adverse effects, could result in substantial soil erosion or the loss of topsoil, could be located on a geologic unit or soil that is unstable, could be located on expansive soil, and could directly destroy a unique paleontological resource or site or unique geologic feature. All potentially significant impacts can be mitigated to less-than-significant levels (See Mitigation Measures GEO-1a, GEO-1b, GEO-1c, GEO-2, and GEO-6). Hazards and Hazardous Materials: Discussed in detail in DEIR Section 3.8. The project could create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials and located on a site which is included on a list of hazardous materials. All potentially significant impacts can be mitigated to a less than significant level (See Mitigation Measure HAZ-1a, HAZ-1b, HAZ-1c, HAZ-1d). Hydrology and Water Quality : Discussed in detail in DEIR Section 3.9. The project could substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces. All potentially significant impacts can be mitigated to less-than-significant levels (See Mitigation Measure HYD-3). Noise: Discussed in detail in DEIR Section 3.11. T The project could cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect and could generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies. All potentially significant impacts can be mitigated to less-than-significant levels (See Mitigation Measures NOI-1 and NOI-2). Recreation : Discussed in detail in DEIR Section 3.13. The project could include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment. All potentially significant impacts can be mitigated to less-than-significant levels (See Mitigation Measures AIR-2, AIR-3, and NOI-2). GENERAL PLAN AND ZONING CONSISTENCY The project is located within the unincorporated Walnut Creek community, where the surrounding uses are primarily residential developments and office uses. The vesting tentative map would subdivide the 5.94-acre project site into 19 residential lots to construct 19 buildings for a total of 125 townhouse condominium units. The project is consistent with the proposed General Plan land use designation of Multiple-Family Residential-High Density (MH), which allows 22.0 – 29.9 units per net acre. The net acreage for the 5.94-acre site is 4.71 acres. The project to construct 125 units would have a density of 26.5 units per net acre, which is within the MH density range. Furthermore, the project is also consistent with General Plan Polices related to Growth Management, 65/35 Land Preservation Standard, Urban Limit Line, Transportation Goals and Policies, and Housing Goals and Policies. The project site is located within the Multiple-Family Residential (M-29 and M-17) and Single-Family Residential (R-15) Zoning Districts. The project includes a rezoning of the 5.94-acre site to P-1. The P-1 zoning district allows flexibility with respect to use, building types, lot size, and open space, while ensuring the project complies with the County’s General Plan and requirements of the County’s Ordinance. The buildings will be setback 15 feet from Jones Road and 10 feet from Oak Road. In order to address comments from the adjacent property owners directly northeast of the project site, the applicant has provided a greater setback than initially proposed. Buildings G and H abut this northeastern residential development and will be setback approximately 26 feet. The buildings located along the southern property line will be at a minimum 15 feet. The proposed three-story residential development is a modern farmhouse style design consisting of stucco siding, horizontal lap siding, and board and batt siding. The building includes vinyl windows and composition roofing shingles. Architectural features also include corbels and metal awnings. The proposed townhouse condominium buildings will be approximately 37 feet to a maximum of approximately 43 feet tall, except for the buildings fronting Oak Road, which contains roof decks. The height for the buildings with roof decks will be approximately 45 feet tall.The project is a multi-family residential infill development, which will be in harmony with the surrounding multi-family residential and transit-oriented developments. COUNTY PLANNING COMMISSION The project was scheduled before the County Planning Commission (CPC) on January 26, 2022. The CPC received testimony from neighbors expressing concerns about building setbacks in the plans presented to the CPC. The applicant indicated that the setbacks had been changed in updated plans and confirmed the agreed upon setbacks from Buildings G and H to the northern property line. No other public testimony was received. The CPC voted to approve (7-0) the vesting tentative map (County File #CDSD21-09559) based on staff's recommendations and recommended that the Board of Supervisors approve the remaining components of the project. CONCLUSION The project will be consistent with applicable goals and policies of the General Plan and with the intent of the MH General Plan designation and the P-1 Zoning district. The project includes 125 townhouse condominium units, which will provide 10 inclusionary housing units and payment for the remaining 8.75 units, and open space area amenities on-site. The subject property is an underutilized site located near high quality transit station (BART), the Iron Horse Regional Trail and the Contra Costa Canal Trail, with extensive office and commercial uses nearby. Overall, the project is consistent with the established surrounding area. The design and use of the project site for townhouse condominium units is consistent with the other uses in the immediate area. Staff recommends that the Board of Supervisors approve the proposed rezoning, and preliminary and final development, based on the attached findings and conditions of approval. Staff also proposed rezoning, and preliminary and final development, based on the attached findings and conditions of approval. Staff also recommends approval of the attached Inclusionary Housing Developer Agreement. CONSEQUENCE OF NEGATIVE ACTION: In the event that the proposed project is not approved, the applicant will not obtain approval of the required Rezoning, and Development Plan entitlements needed to allow development of the proposed 125-unit townhouse condominium project in the unincorporated Walnut Creek area. CHILDREN'S IMPACT STATEMENT: The project involves a subdivision to construct 125 townhouse condominium units. Pursuant to Condition of Approval #12, the applicant shall either contribute funds to CocoKids, directly to childcare center or family care providers, or shall pay the required fee established by the Board of Supervisors per unit for childcare facility needs in the area. Therefore, the recommendation supports one or more of the following children's outcomes: (1) Children Ready for and Succeeding in School; (2) Children and Youth Healthy and Preparing for Productive Adulthood; (3) Families that are Economically Self Sufficient; (4) Families that are Safe, Stable and Nurturing; and (5) Communities that are Safe and Provide a High Quality of Life for Children and Families.

The possible findings are: (a) Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR (hereinafter referred to as “finding (1)”). (b) Such changes or alterations are within the responsibility and jurisdiction of another public agency and not the agency making the finding. Such changes have been adopted by such other agency or can and should be adopted by such other agency (hereinafter referred to as “finding (2)”). (c) Specific economic, legal, social, technological or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the Final EIR (hereinafter referred to as “finding (3)”). The required findings shall be supported by substantial evidence in the record. (Guidelines, § 15091). All significant and potentially significant impacts identified in the Draft EIR can be reduced to levels of insignificance through mitigation measures identified in the Draft EIR. The Final EIR incorporates the Draft EIR. References here within to the “EIR” are to the collective documentation contained in the Draft EIR and Final EIR. 1.2 - Statement of Findings An Environmental Impact Report (EIR) pursuant to CEQA has been prepared by Contra Costa County (Lead Agency). The Draft EIR for the Oak Road Townhouse Condominiums Project (proposed project) identifies significant effects on the environment which may occur as a result of the proposed project. Sections 1.5 and 1.6 set forth potential environmental effects of the proposed project which are not significant because of the design of the proposed project or which can feasibly be mitigated below a level of significance. Section 1.8 summarizes the alternatives discussed in the EIR and makes findings with respect to the feasibility of alternatives and whether the alternatives would lessen the significant environmental effects of the proposed project.

The buildings would be approximately 37 to 43 feet in height to the ridgeline, although the buildings with a rooftop deck may extend up to 45 feet in height. The 5.94-acre site would be developed with a total of approximately 237,816 square feet of new residential living area (293,139 total gross building square feet), resulting in a net density of 26.3 dwelling units per acre. As part of the proposed project, the existing eight parcels would be reconfigured into 19 new residential parcels (1–19), ranging in size from 7,706 square feet to 17,294 square feet, as well as 13 street and court lots (A–M), ranging in size from 2,808 and 9,834 square feet. The building site coverage area would be a maximum of 50 percent of the site (approximately 129,373 square feet). Thirteen of the 125 townhouse condominium units (10 percent) would comply with the Americans with Disabilities Act (ADA). Five unit types are proposed, ranging in size from 1,362 to 2,250 square feet with attached 1- or 2-car garages, 3 to 4 bedrooms, and 3 to 3.5 bathrooms. • Unit type 1A (27 units) would be 1,362 net square feet and 1,811 gross square feet. This unit type would include 3 bedrooms, 3 bathrooms, and a 449-square-foot tandem 2-car garage. • Unit type 1B (6 units) would be 1, 551 net square feet and 1,840 gross square feet. This unit type would include 4 bedrooms, 3 bathrooms, and a 289-square-foot single car garage. • Unit type 2 (20 units) would be 1,837 net square feet and 2,311 gross square feet. This unit type would include 3 bedrooms, 3.5 bathrooms, and a 474-square-foot standard 2-car garage. • Unit type 3 (34 units) would be 2,044 net square feet and 2,493 gross square feet. This unit type would include 4 bedrooms, 3.5 bathrooms, and a 449-square-foot standard 2-car garage. • Unit type 4 (38 units) would be 2,250 net square feet and 2,690 gross square feet. This unit type would include 4 bedrooms, 3.5 bathrooms, and a 440-square-foot standard 2-car garage. A total of 272 on-site parking spaces would be provided with available spaces along the street frontage. Primary vehicular access would be provided from main driveways on Jones and Oak Roads, which would also provide for emergency vehicle access.

Additional common features would include internal streets, courts, walkways, and drainage improvements. Off-site improvements would include installation of parking stalls along Oak Road and Jones Road. The proposed project would involve the demolition of all existing improvements currently present on-site, including buildings, foundations, asphalt, concrete, fence poles, and landscaping. In addition, 74 on-site trees would be removed, and one valley oak (Quercus lobata) would be relocated within the site. Six trees are located adjacent to the property boundaries and have canopies that extend onto the site. Although construction activities would occur within the drip lines of these trees, they would be afforded protection during construction to ensure their preservation. The trees would be pruned in accordance with arborist recommendations to reduce the size of tree crown over the project site. The project site is designated as Multiple-Family Residential–High Density (MH). As part of project approvals, the applicant is requesting rezoning of the site to Planned Unit District (P-1). Primary access to the site would be from two driveways: one along Jones Road and one along Oak Road. Off- site improvements would include frontage sidewalk, driveway curb, gutter improvements including retaining existing on-street parking, and street tree planting. A total of approximately 92,120 square feet of landscaped area (25 percent of the site) is proposed, including a central open space area, paseo/walkways, a dog park, and private yards. 1.3.2 - Project Objectives The objectives of the proposed project are to: • Develop an appropriate mix of multi-family units (including affordable units) that meets the existing General Plan land use designation and regional housing goals. • Provide affordable housing units in accordance with the Contra Costa County Housing Element (2014). • Locate housing in close proximity to transit in order to reduce vehicle miles traveled. • Provide housing with a variety of floor plans and unit types to enhance the economic viability of the development for long-term sustainability. • Retain the architectural and visual character of the neighborhood by building 3-story townhouse condominiums with roof-deck elements on selected homes fronting Oak Road and providing replacement landscaping that will mature over time. • Replace an obsolete private school with new market rate and affordable for-sale townhouse condominium homes consistent with the General Plan and surrounding neighborhood. • Establish physical and social connections between Jones and Oak Roads by building safe, private streets, walkable landscaped open spaces including stormwater management, and green building components. • Provide on-site open space amenities for future residents. • Phase development to allow for managed, orderly, and economically viable growth.

In lieu of a public gathering, the County Zoning Administrator was accessible live online and by telephone to all members of the public as permitted by the Governor’s Executive Order N29-20. During this time, the County Zoning Administrator was available to accept oral and written comments pertaining to environmental concerns related to the proposed project from interested agencies, organizations, and individuals. During this meeting, seven individuals presented verbal comments regarding the proposed project’s impacts on aesthetics, air quality and greenhouse gases, biological resources (specifically, the removal of trees), geology and soils, hazards and hazardous materials, land use and planning, noise, public services and recreation, and transportation and traffic. Additionally, public comments were submitted regarding proposed project’s building setbacks, height, design, foundations, and location, as well as potential effects on parking and neighborhood parks and trails, and construction impacts. These comments were addressed in the Draft EIR. The Draft EIR was circulated for a 45-day public review period between October 21, 2021, and December 6, 2021. During the public review period, the Draft EIR, including the technical appendices, was available for review at the Contra Costa County website (https://www.contracosta.ca.gov/8363/Oak-Road-Townhouse-Condominiums).

Contra Costa County prepared a Final EIR addressing the comment received during the 45-day public review and comment period on the Draft EIR and written responses to that comment. 1.4.2 - County’s Independent Review Contra Costa County independently reviewed and considered the entire administrative record before them, including but not limited to all oral and written comments regarding environmental issues in the Final EIR; written and oral testimony given at public meetings and hearings in connection therewith; the submission of comments from the public, organizations and regulatory agencies; and all other relevant information in the administrative record and determined, based on all of the evidence presented, that the following environmental impacts associated with the proposed project are: (1) less than significant and do not require mitigation; or (2) potentially significant but will be avoided or reduced to a level of insignificance through the identified mitigation measures. Contra Costa County concludes that implementation of the proposed project could result in potentially significant adverse environmental impacts unless mitigation is incorporated. Accordingly, as discussed above, Contra Costa County is required to make certain findings with respect to these impacts pursuant to CEQA Guidelines Section 15091, as set forth in this document (“Findings”). These Findings summarize the environmental determinations about the proposed project’s significant impacts before and after mitigation and summarize the proposed project’s individual and cumulative impacts. These Findings do not attempt to describe the full analysis of each environmental impact. Instead, they provide a summary description of each significant impact and the applicable mitigation measures identified in the Draft EIR and adopted by Contra Costa County and state the conclusions regarding the significance of each impact after incorporation of the identified mitigation measures. A comprehensive explanation of these environmental impact conclusions can be found in the Draft EIR, as supplemented and explained in staff reports and materials presented by the proposed project applicant, Contra Costa County staff, and various project consultants, and other relevant materials in the administrative record. The Draft EIR contains substantial evidence to support all the conclusions presented in these Findings. 1.4.3 - Incorporation of EIR For these Findings, the “EIR” shall consist of the Draft EIR, all appendices attached to the Draft EIR, and the Final EIR (consisting of the Introduction and Responses to Comments). Page references to the EIR will correspond to the page numbering in the publicly released Draft EIR, unless otherwise noted. The EIR is incorporated into these Findings in its entirety. Without limitation, this incorporation is intended to elaborate on the scope and nature of mitigation measures, the basis for determining the significance of impacts, the comparative analysis of alternatives, and the reasons for approving the proposed project.

The EIR reflects the independent judgment of the Contra Costa County and is deemed adequate for purposes of making decisions on the merits of the proposed project. Consistent with Public Resources Code Section 21002.1 and Section 15128 of the CEQA Guidelines, the EIR focused its analysis on potentially significant impacts. CEQA Guidelines Section 15091 does not require specific findings to address environmental effects that an EIR identifies as “no impact” or a “less than significant” impact and for which no mitigation is necessary. Nevertheless, Contra Costa County hereby finds that the proposed project would have either no impact or a less than significant impact as described below. Therefore, based on its independent judgment and the entire administrative record before it, Contra Costa County has determined that the project will have no impact on the following resources areas in their entirety: • Agriculture and Forestry Resources. No agricultural land or forestland currently exist on the project site. The site is mapped as “Urban and Built-Up Land” by the California Department of Conservation Farmland Mapping and Monitoring Program and is not under a Williamson Act Contract. In addition, the General Plan Conservation Element Figure 8-2 does not delineate the project site as an Important Agricultural Area. As such, construction and operation of the proposed project would not result in the conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide Importance to non-agricultural uses or result in the loss or conversion of forestland to non-forest uses. The proposed project would not conflict with any zoning for agricultural use or a Williamson Act Contract or any zoning for forestland or timberland. Therefore, Contra Costa County determines that substantial evidence supports a finding that no impacts related to agriculture or forestry resources would occur (Draft EIR, Chapter 6: Effects Found not to be Significant, Page 6-1). • Mineral Resources. There are no mineral resource recovery sites on or in the project vicinity. A Mineral Resource Zones and Resources Sectors map prepared by the California Geological Survey indicates that the project site is located in an area that does not contain any known mineral occurrences. There are no mines on the site or in the project vicinity. In addition, the General Plan Conservation Element Figure 8-4 indicates that no mineral resource zones are located on the project site or within the surrounding area. The site is designated as Multiple- Family Residential–High-Density (MH) by the General Plan; as such, construction and operation of the proposed project would not result in the loss of availability of a known mineral resource of value to the region and residents of the State. Therefore, Contra Costa County determines that substantial evidence supports a finding that no impacts related to mineral resources would occur (Draft EIR, Chapter 6: Effects Found not to be Significant, Page 6-2).

Therefore, based on its independent judgment and the entire administrative record before it, Contra Costa County has determined that the following potential environmental effects will not be significant and no mitigation is necessary for the reasons stated below. 1.5.1 - Aesthetics, Light, and Glare Potential Effect Impact AES-1 The proposed project would not have a substantial adverse effect on a scenic resource as identified in the General Plan (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-9). Findings Less than significant impact. Facts in Support of Findings There are no scenic resources, as defined by the General Plan, located on the project site. The nearest designated scenic resource to the project site is Diablo Ridge, located approximately 2.35 miles to the southeast, approximately 3.95 miles to the east, and approximately 7.45 miles to the northeast. The nearest scenic roads designated by the General Plan are Interstate 680 (I-680) and State Route (SR) 24, which intersect approximately 1.9 miles south of the site. Due to distance and intervening development, the project site is not visible from any scenic routes. During construction, removal of the buildings and vegetation would not adversely impact existing views within the project vicinity because the project site does not contain any designated scenic resources and is not visible from the nearest designated scenic routes, I-680 and SR-24. During operation, implementation of the proposed project would not result in a substantial adverse effect on a scenic vista because there are no scenic ridges, hillsides, or rock outcroppings on the project site, nor are any scenic resources visible from the project site nor would development of the project site interfere with views of any scenic resources (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-9). Potential Effect Impact AES-2 The proposed project would not substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic building within a State Scenic Highway (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-10). Findings Less than significant impact.

In addition, there are no scenic resources, as designated by the General Plan located on the project site. Given the absence of scenic highways proximate to the project site, the lack of designated scenic resources (i.e., ridgelines, hillsides, rock outcroppings) on the project site, and the presence of intervening development between the project site and the nearest scenic highways, the proposed project would not adversely affect views from a State Scenic Highway (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-10). Potential Effect Impact AES-3 The proposed project is in an urbanized area and would not conflict with applicable zoning and other regulations governing scenic quality (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-10–11). Findings Less than significant impact. Facts in Support of Findings Considering the residential character of the project site surroundings, construction activities could temporarily affect existing visual character or quality of the project site and area. However, the area surrounding the project site has a transit-oriented residential character with multi-family apartments located to the north and to the south. The construction of the proposed project would temporarily affect visual character and quality of the area. However, construction-related impacts related to degradation of existing visual character or quality of the project site and area would be nominal, temporary, and less than significant. The proposed project would change the visual character of the site. However, the proposed project would be consistent with the character of the surrounding area, as the area continues to transition toward higher density multi-family residential uses. The General Plan designates the site as Multiple- Family Residential–High Density (MH). As part of project implementation, the zoning of the project site would be changed to Planned Unit District (P-1). The P-1 Zoning District is intended to support large-scale integrated development in compliance with the General Plan designations. The proposed project would be consistent with the Design Objectives identified in Section 84-66.1402 of the Ordinance Code related to the P-1 Zoning District. For example, the buildings bulk, height, land coverage, and visual appearance is compatible with existing adjoining development. In addition, the design of the buildings provides for harmonious composition of mass, scale, color, and textures. The proposed project also includes implementation of a landscaping plan, including approximately 250 trees and hundreds of shrubs, vines, and groundcover. The establishment of trees and other plantings would support the transition of the site to reflect the residential character of surrounding properties (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-10–11).

Findings Less than significant impact. Facts in Support of Findings Cumulative projects are identified in Table 3-1 of the Draft EIR. The degree to which past projects are included within the list of projects is generally limited, due to the fact that past projects are included in the current environmental conditions already considered as part of the baseline and existing environmental setting. None of the Cumulative Projects would be located within the same visible area as the proposed project. The proposed project and Cumulative Projects 1 and 2, as provided in Table 3-1 of the Draft EIR, would be subject to the same County codes and guidelines related to lighting, building heights, setbacks, undergrounding of utilities, landscaping, signage, and permitted land uses. Cumulative Projects 3–13 in the Draft EIR would be subject to the codes and guidelines associated with the City of Walnut Creek related to lighting, building heights, setbacks, undergrounding of utilities, landscaping, signage, and permitted land uses. Cumulative Projects 14– 24 in the Draft EIR would be subject to the codes and guidelines associated with the City of Pleasant Hill related to building heights, setbacks, undergrounding of lighting, utilities, landscaping, signage, and permitted land uses. As such, the proposed project, in conjunction with other planned and approved projects, would result in a less than significant cumulative impact with respect to visual character, views, lighting and glare. 1.5.2 - Air Quality Potential Effect Impact AIR-1 The proposed project would not conflict with or obstruct implementation of the applicable air quality plan (Draft EIR, Section 3.2, Air Quality, Page 3.2-37). Findings Less than significant impact. Facts in Support of Findings The Bay Area Air Quality Management District (BAAQMD) is responsible for reducing emissions from area, stationary, and mobile sources in the Air Basin to achieve National Ambient Air Quality Standards (NAAQS) and California Ambient Air Quality Standards (CAAQS). The BAAQMD 2017 Clean Air Plan is a regional and multiagency effort to reduce air pollution in the Air Basin. A project would be judged to conflict with or obstruct the 2017 Clean Air Plan implementation if it would result in substantial new regional emissions not foreseen in the air quality planning process. The BAAQMD does not provide a numerical threshold of significance for project-level consistency analysis with Air Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 11 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Quality Plans (AQPs). Therefore, the following criteria was used for determining the project’s consistency with the AQP. • Criterion 1: Does the project support the primary goals of the AQP? • Criterion 2: Does the project include applicable control measures from the AQP? • Criterion 3: Does the project disrupt or hinder implementation of any AQP control measures? Criterion 1: The proposed project’s density and use would be consistent with the General Plan land use designation and the proposed project would not require a General Plan Amendment. The proposed project would not introduce a greater amount of population growth than what was envisioned by the General Plan and, subsequently, the AQP. Therefore, the anticipated population growth facilitated by the proposed project was anticipated in the 2017 Clean Air Plan and the project would not conflict with the goals contained in the AQP. The proposed project is consistent under Criterion 1. Criterion 2: As shown in the Consistency Analysis on Page 3.2-39 to Page 3.2-42 of the Draft EIR, the proposed project would be consistent with applicable measures in the 2017 Clean Air Plan and would not conflict with or hinder BAAQMD from implementing the control measures in the 2017 Clean Air Plan. The proposed project is consistent under Criterion 2. Criterion 3: The proposed project would not preclude extension of a transit line or bike path, propose excessive parking beyond parking requirements, or otherwise create an impediment or disruption to implementing any AQP control measures. The proposed project would incorporate several AQP control measures as project design features. Considering this information, the proposed project would not disrupt or hinder the implementation of any AQP control measures. Therefore, the proposed project would be consistent under Criterion 3. The proposed project would be consistent with all three criteria after the incorporation of identified mitigation, and therefore, the proposed project ’s related impacts would be less than significant (Draft EIR, Section 3.2, Air Quality, Pages 3.2-37–43). Potential Effect Impact AIR-4 The proposed project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people (Draft EIR, Section 3.2, Air Quality, Page 3.2-53). Findings Less than significant impact. Facts in Support of Findings During construction activities, construction equipment exhaust and application of asphalt and architectural coatings would temporarily generate odors. Any construction-related odor emissions would be temporary and intermittent. Additionally, noxious odors would be confined to the immediate vicinity of the construction equipment. It is anticipated that by the time such emissions Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 12 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx reach any sensitive receptor sites, they would be diluted to well below any level of air quality or odor concern; therefore, impacts would be less than significant. Operation of the proposed project would likely not generate objectionable odors. The type of uses that are considered to have objectionable odors include wastewater treatments plants, compost facilities, landfills, solid waste transfer stations, fiberglass manufacturing facilities, paint/coating operations (e.g., auto body shops), dairy farms, petroleum refineries, asphalt batch plants, chemical manufacturing, and food manufacturing facilities. As the proposed project is residential in nature, it is not anticipated to generate objectionable odors which may affect a substantial number of people (Draft EIR, Section 3.2, Air Quality, Page 3.2-53). 1.5.3 - Biological Resources Potential Effect Impact BIO-2 The proposed project would not have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service (Draft EIR, Section 3.3, Biological Resources, Page 3.3-21). Findings No impact. Facts in Support of Findings The project site is developed and is almost entirely covered with impervious surfaces due to existing development to the extent that no natural habitat remains present on-site. The trees that are present are located in pockets surrounded by hardscaped areas. Historical aerial photographs indicate that most of the oak trees on-site appear to be ornamental plantings; thus, they are not part of a natural community (e.g., naturally occurring oak savanna or oak woodland). The project site does not contain riparian habitat or other sensitive natural communities identified in local or regional plans, policies, and regulations or by the California Department of Fish and Wildlife (CDFW) or United States Fish and Wildlife Service (USFWS) (Draft EIR, Section 3.3, Biological Resources, Page 3.3-21). Therefore, the proposed project would have no impact on an identified riparian habitat or sensitive natural community. Potential Effect Impact BIO-3 The proposed project would not have a substantial adverse effect on State or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means (Draft EIR, Section 3.3, Biological Resources, Page 3.3-22). Findings No impact. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 13 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Facts in Support of Findings The project site is developed and does not contain jurisdictional drainages, wetlands, or hydrophytic vegetation or soils. On-site stormwater runoff sheet flows across the project site and is captured by drainage inlets connected by municipal underground storm drain pipes that discharge into existing storm drainage infrastructure. As such, the proposed project would not directly or indirectly remove, fill, or hydrologically interrupt State or federally protected wetlands (Draft EIR, Section 3.3, Biological Resources, Page 3.3-22). For these reasons, the proposed project would have no impact on protected wetlands. Potential Effect Impact BIO-4 The proposed project would not interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of wildlife nursery sites (Draft EIR, Section 3.3, Biological Resources, Page 3.3-22). Findings Less than significant impact. Facts in Support of Findings The project site is in a built out urban area and does not contain any habitat features such as riparian corridors or waterways that could function as wildlife corridors. Moreover, there are multiple barriers to wildlife migration including I-680 and multiple residential and commercial developments, which further precludes wildlife movement (Draft EIR, Section 3.3, Biological Resources, Pages 3.3- 22–23). Therefore, the proposed project does not have the potential to substantially reduce the habitat of any species or interfere with movement and impacts are less than significant. Potential Effect Impact BIO-6 The proposed project would not conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State Habitat Conservation Plan (Draft EIR, Section 3.3, Biological Resources, Page 3.3-24). Findings No impact. Facts in Support of Findings The project site does not fall within the coverage area of a Habitat Conservation Plan (HCP) or Natural Community Plan (NCCP). The project site is roughly 5 miles west of the East Contra Costa County HCP area, the nearest Habitat Conservation Plan area (Draft EIR, Section 3.3, Biological Resources, Page 3.3-24). Accordingly, no impacts would occur. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 14 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Potential Effect Cumulative Impact Implementation of the project, in conjunction with other planned and approved projects, would result in less than significant cumulative impacts to biological resources (Draft EIR, Section 3.3, Biological Resources, Page 3.3-26). Findings Less than significant impact. Facts in Support of Findings Special-status Species While there are a limited number of isolated pockets of natural habitat that can support special- status wildlife and plant species, the built-up nature of the cumulative project areas precludes the possible cumulative impacts to biological resources related to special-status wildlife and plant species. However, the varying degree of trees present in and around the urban areas may provide suitable nesting habitat for birds protected by the Migratory Bird Treaty Act (MBTA ). Standard pre- construction surveys and, if necessary based on the survey results, avoidance procedures would be required for cumulative projects with the potential to impact nesting birds and protected bat species (Draft EIR, Section 3.3, Biological Resources, Page 3.3-25). For these reasons, cumulative impacts are less than significant. Additionally, as discussed above, the project’s contribution to the less than significant cumulative impacts is not cumulatively considerable. Sensitive Natural Communities or Riparian Habitat Within the County, the City of Pleasant Hill, and the City of Walnut Creek, there are several small waterbodies, including the Walnut Creek waterway, Grayson Creek, and associated riparian habitats. These areas are considered sensitive natural communities. The majority of current developments are designed to address future growth problems, prevent urban sprawl, and minimize developmental impacts to sensitive natural communities. This is accomplished by designing projects to occur in previously developed or highly disturbed areas that the characteristics of lack sensitive natural communities or riparian habitat. As such, the project, in conjunction with other cumulative projects, would result in a less than significant cumulative impact related to sensitive natural communities and associated riparian habitat (Draft EIR, Section 3.3, Biological Resources, Page 3.3-25). Waters of the United States and Waters of the State The County, the City of Pleasant Hill, and the City of Walnut Creek contain several areas that would be considered jurisdictional features. As such, current projects are occurring in a highly developed and disturbed area with low potential for jurisdictional features to be impacted by project development. If any issues were to arise due to current development, the applicant would be required to obtain appropriate permits from the United States Army Corp of Engineers (USACE), Regional Water Quality Control Board (RWQCB), and CDFW and to compensate for loss of waters of the United States/State through re-creation or payment of mitigation credits and re-creation of lost habitat. Due to the limited scope of current projects, which are occurring in highly developed and disturbed areas, it is expected there will be a less than significant cumulative impact related to waters of the United States/State (Draft EIR, Section 3.3, Biological Resources, Page 3.3-25). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 15 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Local Policies or Ordinances Many of the current development projects are occurring in previously developed or disturbed areas. As such, a limited number of trees within the geographical scope are likely to occur. Current project developments may require an Arborist report to determine the identity of trees planned for removal or encroachment. Therefore, the project, in conjunction with other future development projects, would be required to adhere to applicable tree ordinances and regulations set by the County and the City of Walnut Creek and City of Pleasant Hill resulting in a less than significant cumulative impact to biological resources related to local policies and ordinances (Draft EIR, Section 3.3, Biological Resources, Pages 3.3-25–26). Fish and Wildlife Movement Corridors The main wildlife corridor in the vicinity of the project site is the Walnut Creek waterway, which generally borders the I-680 corridor, stretching from northern San Ramon to Suisun Bay. There are several small water channels and tributaries that are located within the geographical scope of this project. The project site is located to the west of the waterway and due to the size and location of the proposed project it will not result in any potential impacts to wildlife corridors. Any current development that occurs within the geographic scope of the County, the City of Walnut Creek and the City of Pleasant Hill will have to take into account the potential impact to these corridors. The areas surrounding the potential corridors within the previously mentioned geographical scope are highly developed, further impeding the movement of species out from these areas. As such, there will be a less then significant cumulative impact to biological resources related to movement corridors for fish and wildlife (Draft EIR, Section 3.3, Biological Resources, Page 3.3-26). Additionally, because the proposed project site does not contain any habitat or movement corridors, the project’s contribution to the less than significant cumulative impacts is not cumulatively considerable. Habitat and Natural Community Conservation Plan Consistency The project site is not located within the East Contra Costa County HCP. The HCP provides for comprehensive species, wetlands, and ecosystem conservation, and contributes to the recovery of endangered species in Eastern Contra Costa County. Any current project sites within the boundaries of the HCP will have to adhere to the additional regulations and guidelines established by the HCP. This may include additional surveys for listed species, developments fees, and various other directives. As such, there will be a less then significant cumulative impact to biological resources relating to developments occurring in Habitat Community Conservation Plans. Additionally, because the proposed project is not located within an HCP or NCCP, the proposed project’s contribution to the less than significant cumulative impacts is not cumulatively considerable (Draft EIR, Section 3.3, Biological Resources, Page 3.3-26).

Findings Less than significant impact. Facts in Support of Findings Construction of the proposed project was assumed to begin in September 2022 and continue through November 2023. If the construction schedule moves to later years, construction energy demand would likely decrease because of improvements in technology and more stringent regulatory requirements. Project construction would require energy for the manufacture and transportation of building materials, preparation of the site (e.g., demolition, site clearing, and grading), and the actual construction of the buildings. Petroleum-based fuels such as diesel fuel and gasoline would be the primary sources of energy for these tasks. Much of the energy consumption is likely to occur in the first year when demolition, site preparation, and grading activities occur. The types of on-site equipment used during construction of the proposed project could include gasoline- and diesel-powered construction and transportation equipment, including trucks, bulldozers, frontend loaders, forklifts, and cranes. Construction equipment is estimated to consume a total of 36,941 gallons of diesel fuel over the entire construction duration (Draft EIR, Section 3.5, Energy, Page 3.5-11). Fuel use associated with construction vehicle trips generated by the proposed project was also estimated. In total, the proposed project is estimated to generate 498,347 Vehicle Miles Traveled (VMT) and a combined 23,042 gallons of gasoline and diesel for vehicle travel during construction (Draft EIR, Section 3.5, Energy, Page 3.5-12). Other equipment could include construction lighting, field services (office trailers), and electrically driven equipment such as pumps and other tools. Singlewide mobile office trailers, which are commonly used in construction staging areas, generally range in size from 160 square feet to 720 square feet. A typical 720-square-foot office trailer would consume approximately 15,722 kilowatt hours (kWh) during the 1.2-year construction phase. This energy use is typical and consistent with other similar energy efficient projects. Additionally, the proposed project’s construction is not anticipated to result in unusually high energy use. Limitations on idling of vehicles and equipment and requirements that equipment be properly maintained would minimize the use of fuel. Similarly, compliance with State regulations would limit idling from both on-road and off-road diesel-powered equipment and are enforced by the California Air Resources Board (ARB). Additionally, the overall construction schedule and process is already designed to be efficient in order to avoid excess monetary costs. For example, equipment and fuel Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 17 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx are not typically used wastefully due to the added expense associated with renting the equipment, maintaining it, and fueling it. Therefore, the opportunities for future efficiency gains during construction are limited (Draft EIR, Section 3.5, Energy, Page 3.5-12). The proposed project would consume energy as part of building operations and transportation activities. Unmitigated operation of the proposed project would consume an estimated 635,439 kWh of electricity and an estimated 0 kilo-British thermal unit (kBTU) of natural gas on an annual basis. The proposed project’s buildings would be designed and constructed in accordance with the County’s latest adopted energy efficiency standards, which are based on the State’s Building Energy Efficiency Standards. These are widely regarded as the most advanced building energy efficiency standards, and compliance would ensure that building energy consumption would not be wasteful, inefficient, or unnecessary. The proposed project is designed be all electric construction in the new homes with no natural gas provided. Each home will also have rooftop solar panels (Draft EIR, Section 3.5, Energy, Page 3.5-13). In total, the proposed project would consume 63,021 gallons of gasoline and diesel per year starting in 2023. The majority of operational fuel consumption would be from employee vehicle emissions, which would be regulated by State and federal policies and could not be feasibly mitigated by the proposed project or County. The site is served by several County Connection bus routes: 7, 9, 11, 14, 15, and 311. The closest bus stop to the project site is located at Oak Road and Walden Park, approximately 970 feet south of the project site. There are sidewalks on Oak Road that provide connectivity to the bus stop. There are no existing bike lanes on Jones Road. The Iron Horse Regional Trail, located approximately 1,500 feet east of the project site, provides a multiuse bicycle/pedestrian pathway, which access to the Pleasant Hill Bay Area Rapid Transit (BART) station. There is also another bicycle/pedestrian trail, Contra Costa Canal Trail, located approximately 450-600 feet south of the project site, which crosses Oak Road and Jones Road. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. The proposed project would not affect existing and planned bicycle facilities. The project also proposes to include a bike repair space on-site. As a result, the proposed project is located near regional and local roadway. Transportation fuel consumption would not be wasteful, inefficient, or unnecessary (Draft EIR, Section 3.5, Energy, Page 3.5-13). For these reasons, impacts would be less than significant. Potential Effect Impact ENER-2 The proposed project would not conflict with or obstruct a State or local plan for renewable energy or energy efficiency (Draft EIR, Section 3.5, Energy, Page 3.5-13). Findings Less than significant impact. Facts in Support of Findings The proposed project would be designed in accordance with Title 24, California’s Energy Efficiency Standards for Residential Buildings. These standards include minimum energy efficiency Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 18 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx requirements related to building envelope, mechanical systems (e.g., heating, ventilation, and air conditioning [HVAC] and water heating systems), and indoor and outdoor lighting. Furthermore, the proposed rooftop solar panels would supply, at least in part, the additional electricity demand for appliances. The incorporation of the Title 24 standards into the design of the proposed project would ensure that the proposed project would not result in the use of energy in a wasteful manner. Furthermore, the proposed rooftop solar panels would supply the increased electricity demand. (Draft EIR, Section 3.5, Energy, Page 3.5-14). Compliance with Title 24 standards would ensure that the proposed project would not conflict with any of the Conservation Element energy conservation policies related to the proposed project’s building envelope, mechanical systems, and indoor and outdoor lighting. Moreover, the proposed project would be consistent with the greenhouse gas (GHG) emissions reduction measures contained in the County’s Climate Action Plan (CAP), which are closely related to and include energy efficiency measures. The proposed project would comply with existing State energy standards and be consistent with the energy efficiency goals and measures contained in the County’s General Plan Conservation Element and CAP. As such, the proposed project would not conflict with State or local renewable or energy efficiency objectives (Draft EIR, Section 3.5, Energy, Page 3.5-14) and impacts would be less than significant Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in a less than significant cumulative impact with respect to the wasteful or inefficient use of energy. (Draft EIR, Section 3.5, Energy, Page 3.5-15). Findings Less than significant impact. Facts in Support of Findings The geographic scope of the cumulative energy analysis is the portion of Pacific Gas and Electric Company (PG&E’s) service area that covers incorporated and unincorporated County. Cumulative projects would be required to comply with Title 24 Building Energy Efficiency Standards and the California Green Building Standards Code (CALGreen). The cumulative buildings would be designed in accordance with Title 24, California’s Energy Efficiency Standards for Residential Buildings as applicable. These standards include minimum energy efficiency requirements related to building envelope, mechanical systems (e.g., HVAC and water heating systems), and indoor and outdoor lighting. Future development would also be required to meet even more stringent energy efficiency requirements through local and Statewide policy, such as Title 24, Part 6, which would require that newly constructed residential homes include on-site photovoltaic solar systems, with some exceptions. Furthermore, PG&E, which supplies electricity to the project area, would be required by Senate Bill (SB) 100 to incrementally increase the proportion of renewable electricity generation supplying its in-state retail sales until it reaches 100 percent carbon-free electricity generation by 2045 (Draft EIR, Section 3.5, Energy, Page 3.5-14).

Cumulative projects would be required to comply with California Code of Regulations Title 13, Sections 2449(d)(3) and 2485, that limit idling from both on-road and off-road diesel-powered equipment and are enforced by the ARB. Additionally, various federal and State regulations, including the low carbon fuel standard (LCFS), Pavley Clean Car Standards, and Low Emission Vehicle (LEV) Program, would serve to reduce the transportation fuel demand of cumulative projects. Compliance with these regulations by the cumulative projects would ensure that the cumulative projects would not result in the inefficient, unnecessary, or wasteful consumption of fuel and the cumulative impact would be less than significant (Draft EIR, Section 3.5, Energy, Page 3.5-15). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project would not have a significant incremental contribution to cumulative impacts. The proposed project’s energy use would be limited to that which is necessary for the construction and operation of the proposed project. The proposed project would comply with Statewide and local policies pertaining to energy efficiency and would reasonably pursue greater energy efficiencies in its operation in the interest of reducing operating costs. Consistency with the local, State, and federal regulations cited above would be required during the design review process to ensure that projects comply with all applicable policies, including requirements in the California Energy Code. Therefore, the proposed project’s contribution to cumulative impacts would be considered less than significant. 1.5.5 - Geology and Soils Potential Effect Impact GEO-5 The proposed project would not have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-19). Findings No impact. Facts in Support of Findings Impacts related to soil capability of supporting the use of alternative wastewater disposal systems are limited to operational impacts; therefore, there are no construction impacts. The proposed project does not include the use of septic tanks or alternative wastewater disposal systems. The proposed project is located within an urbanized portion of the County and would include wastewater infrastructure and connections to the existing sanitary sewer lines contained with Oak Road (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-19). Accordingly, there is no impact.

Findings Less than significant impact. Facts in Support of Findings The geographic scope of the cumulative analysis related to geology and soils is the project site and its vicinity. Adverse effects associated with geology and soils tend to be localized; therefore, an area generally within a 0.25-mile radius would be the area most affected by activities associated with the proposed project. Seismic-related Hazards None of the cumulative projects are located within 0.25 mile of the project site. Cumulative projects, including the proposed project, have the potential to experience moderate to strong ground shaking from earthquakes. Cumulative projects would be exposed to the same ground shaking hazards and would be subject to the same requirements as the proposed project. Cumulative projects would adhere to the provisions of the California Building Standards Code (CBC), policies of the General Plan, and the Municipal Code or Ordinance Code to reduce potential hazards associated with seismic ground shaking and ground failure (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-21). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project would not have a significant incremental contribution to cumulative impacts because adverse effects associated with seismic hazards tend to be localized and there are no cumulative projects within 0.25 mile of the project site. Soil-related Hazards Soil conditions associated with the project site, such as expansive soils, corrosive soils, and soil settlement, are specific to the project site and generally do not contribute to a cumulative effect. Some or all other cumulative projects may have similar conditions, but they would not contribute to cumulative soil-related hazards. Other current and future development/redevelopment projects in the region would similarly be required to adhere to standards and practices that include stringent geologic and soil-related hazard mitigations (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-21). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project would not have a significant incremental contribution to cumulative impacts because the proposed project would be subject to General Plan policies and the Ordinance Code be required during the design review process to ensure that projects comply with all applicable policies to reduce soil-related hazards. Paleontological Resources and Unique Geologic Feature None of the cumulative projects would occur within 0.25 mile of the project site. Construction activities associated with development of cumulative projects in the project vicinity may have the Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 21 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx potential to encounter undiscovered geologic resources or paleontological resources. These cumulative projects would be required to mitigate for impacts through compliance with applicable federal and State laws governing geologic resources and paleontological resources. The likelihood that geologic resources or paleontological resources are present on the cumulative project sites is relatively low, given that the majority of soil disturbance associated with these projects will take place within Holocene soils too young to be fossiliferous. Although there is the possibility that previously undiscovered resources could be encountered by subsurface earthwork activities, the implementation of standard construction practices and Mitigation Measure (MM) GEO-6, which requires the cessation of construction activities in the event of an unanticipated discovery, would ensure that undiscovered geologic resources and paleontological resources are not adversely affected by cumulative project-related construction activities. Accordingly, potential cumulative impacts would be less than significant, and no mitigation is necessary. Moreover, the proposed project would not have a significant incremental contribution to cumulative impacts because adverse geological or soils effects tend to be localized or specific to the project site, and there are no cumulative projects located within 0.25 mile of the project site. Given the low potential for disruption and the comprehensiveness of mitigation measures that would apply to the cumulative projects, the project, in conjunction with other planned and approved projects, would result in a less than significant cumulative impact related to paleontological and geologic resources (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-21). 1.5.6 - Greenhouse Gas Emissions Potential Effect Impact GHG-1 The proposed project would not generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment (Draft EIR, Section 3.7, Greenhouse Gas Emissions, Page 3.7-41). Findings Less than significant impact. Facts in Support of Findings GHG emissions associated with development of the proposed project would occur over the short term from construction activities, consisting primarily of emissions from equipment exhaust and worker and vendor trips. There would also be long-term operational emissions associated with vehicular traffic within the project vicinity, energy and water usage, and solid waste disposal (Draft EIR, Section 3.7, Greenhouse Gas Emissions, Page 3.7-41). GHG emissions associated with construction were estimated to be 368 metric tons (MT) of carbon dioxide equivalent (CO2e) for the total construction period. These would represent the GHG emissions generated from on-site operation of construction equipment, vendor and hauling truck trips, and worker trips. The proposed project would contribute to global climate change through direct and indirect emissions of GHG from transportation sources (passenger vehicles, trucks), energy (natural gas and purchased energy), water use and wastewater generation, and solid waste generation. According to Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 22 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx the California Emissions Estimator Model (CalEEMod), the proposed project is estimated to consume approximately 635,440 kWh per year, and according to the solar system capacity calculations, the proposed project would generate an estimated 301,400 kWh per year. Therefore, the electricity related GHG emissions estimated for project operation were reduced to reflect the GHG emissions generated from the electricity consumed that would not be covered by the rooftop solar system. As shown in Table 3.7-5, the annual GHG emissions resulting from operation of the proposed project are estimated to be 677 MT of CO2e in 2024 and would exceed the 660 MT CO2e/year bright-line threshold (Draft EIR, Table 3.7-5: Annual Project GHG Emissions, Page 3.7-43). While the proposed project would involve demolition of the existing Palmer School and it is normal practice to include existing emission estimates to demonstrate net GHG emissions resulting from the proposed project, the Palmer School was not in operation at the time the NOP was issued for this project. Nonetheless, because the school could become operational in the future, operational GHG emission estimates for operation of Palmer School are provided in Table 3.7-6 of the Draft EIR for informational purposes (Page 3.7-44). The proposed project was analyzed against the efficiency threshold which was calculated to demonstrate consistency with the 40 percent below 1990 emission levels reduction target of SB 32. The proposed project would not exceed the efficiency threshold and would be consistent with the GHG emission reductions required under SB 32 (Draft EIR, Table 3.7-5: Annual Project GHG Emissions, Page 3.7-44). Accordingly, the proposed project would not have a significant effect with respect to greenhouse gas emissions. Potential Effect Impact GHG-2 The proposed project would not conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases (Draft EIR, Table 3.7-5: Annual Project GHG Emissions, Page 3.7- 44). Findings Less than significant impact. Facts in Support of Findings The EIR discusses project consistency with applicable plans adopted for the purpose of reducing GHG emissions, which include ARB’s Scoping Plan and the Contra Costa County CAP. The proposed project incorporates several design elements that would reduce GHG emissions, such as conformance to the 2019 Building Energy Efficiency Standards and CALGreen building regulations and installation of a photovoltaics (PV) system. In addition, a development checklist under the County’s CAP was filled out for the proposed project to demonstrate compliance. The proposed project would also be consistent with the measures in the County CAP (Draft EIR, Table 3.7-7: Contra Costa County Climate Action Plan Consistency, Page 3.7-45). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 23 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Potential Effect Cumulative Impacts The proposed project, in conjunction with other present, planned, and approved projects, would result in a less than significant cumulative impact related to GHG emissions generation (Draft EIR, Section 3.7, Greenhouse Gas Emissions, Page 3.7-47). Findings Less than significant impact. Facts in Support of Findings GHG emissions and global climate change inherently represent cumulative impacts. GHG emissions cumulatively contribute to the significant adverse environmental impacts of global climate change. No single project could generate enough GHG emissions to noticeably change the global average temperature; instead, the GHG emissions from past, present, and future projects and activities have contributed to and would contribute to global climate change and its associated environmental impacts. According to the BAAQMD, project GHG emissions are inherently cumulative and do not require the estimation of cumulative projects in the region of the project. Thus, the determination of GHG cumulative impacts is based on the State target established by Assembly Bill (AB) 32 to reduce GHG emissions to 1990 levels by 2020. In order to ensure that this goal would be achieved, Air Districts and Lead Agencies developed GHG thresholds to ensure compliance with the State target. Projects with GHG emissions in conformance with these thresholds, therefore, would not be considered significant for purposes of CEQA. As analyzed in Impact GHG-1, the proposed project would have a GHG emissions benefit when compared to the emissions generated by existing land uses, or the environmental baseline, and would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing GHG emissions. Although the emissions from cumulative projects would add an incremental amount to the overall GHG emissions that cause global climate change impacts, because emissions from the proposed project are below the applicable GHG significance thresholds, the proposed project would not present a “cumulatively considerable” contribution to GHG emission impacts under CEQA (Draft EIR, Section 3.7, Greenhouse Gas Emissions, Page 3.7-47). Accordingly, the proposed project’s contribution to cumulative greenhouse gas emissions is less than significant. 1.5.7 - Hazards and Hazardous Materials Potential Effect Impact HAZ-2 The proposed project would not create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials into the environment (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-22). Findings Less than significant impact. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 24 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Facts in Support of Findings Construction activity within the project site and within the areas proposed for the off-site improvements would involve the transport, use, and disposal of hazardous materials, such as diesel fuels, aerosols, and paints. The use of these materials would be subject to the Hazardous Materials Tran sportation Act, California Public Resources Code, and other State and local regulations that would limit the use of hazardous materials and reduce the associated risks of exposure. Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations, including the United States Environmental Protection Agency (EPA ), Resource Conservation and Recovery Act (RCRA), California Department of Transportation (Caltrans), the Hazardous Materials Transportation Act, and the Contra Costa County Hazard Mitigation Plan (HMP) (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-22). The proposed project is residential and does not include industrial or retail development that involves hazardous materials such as gas stations, paint stores, or auto parts stores. Unlike industrial or retail facilities, residential development does not involve the type or quantity of hazardous materials that could pose a significant environmental accident. Small quantities of hazardous materials would be used on-site during operation of the project but not in sufficient quantities to create a significant hazard. These types of materials are common in residential projects and represent a low risk to people and the environment when used as intended and would not be expected to result in the release of hazardous materials into the environment. (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-23). Accordingly, impacts are less than significant. Potential Effect Impact HAZ-3 The proposed project would not emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-23). Findings Less than significant impact. Facts in Support of Findings The project site, including the areas proposed for off-site improvements, are not located within 0.25 mile of an existing or proposed school. The closest school, Fusion Academy (a private school), is located approximately 0.33 mile to the north. Construction activity would be expected to involve the transport, use, and disposal of hazardous materials, such as diesel fuels, aerosols, and paints. The handling, transport, use, and disposal of hazardous materials must comply with the Hazardous Materials Transportation Act, California Public Resources Code, and other State and local regulations, which further limits the risk of emissions. The proposed project does not include industrial or retail development that involves hazardous materials such as gas stations, paint stores, or auto parts stores. Unlike industrial or retail facilities, residential development does not involve the type or quantity of hazardous materials that could pose a significant environmental accident (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-23). As such, the proposed project would not Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 25 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx emit hazardous emissions or handle hazardous materials within 0.25 mile of a school and impacts would be less than significant. Potential Effect Impact HAZ-5 The proposed project would not be located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, and result in a safety hazard or excessive noise for people residing or working the project area (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-24). Findings No impact. Facts in Support of Findings The proposed project would not be located within an airport land use plan or within 2 miles of a public airport. The closest public airport, Buchanan Field, is located approximately 4.4 miles to the north of the project site (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-25). Potential Effect Impact HAZ-6 The proposed project would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-25). Findings Less than significant impact. Facts in Support of Findings The proposed project would comply with the Contra Costa County Emergency Plan, ensuring efficient response to emergency incidents associated with emergencies affecting Contra Costa County during construction. Additionally, during operation, the proposed project would adhere to the procedures of the Contra Costa County Operational Area Emergency Operations Plan (EOP). The population growth anticipated with the proposed project would be within the General Plan’s 2020 population and dwelling projections for the unincorporated area and, therefore, would not be considered substantial. Furthermore, it would also be within the Association of Bay Area Government (ABAG’s ) 2020-2040 regional population growth projections. Therefore, the proposed project would not create a permanent increase in population unaccounted for in the General Plan that could lead to overwhelming call for police and fire services. In addition, the project site would be designed in accordance with the County’s standards to accommodate emergency vehicle access by providing two points of access that would be available to emergency vehicles (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-25). Impacts would be less than significant. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 26 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Potential Effect Impact HAZ-7 The proposed project would not expose people or structures, either directly or indirectly to a significant risk of loss, injury or death involving wildland fires (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-26). Findings Less than significant impact. Facts in Support of Findings Fire hazards present a considerable problem throughout the County, primarily within undeveloped areas with natural vegetation and steep slopes. The project site is surrounded by urbanized uses on areas relatively flat in elevation, lacking in woodlands or vegetation that could provide fuel load for wildfire or steep slopes that could cause fire to spread more rapidly. The project site is surrounded by other features that provide fuel breaks in the event of a fire, such as Oak Road and Jones Road. In addition, the Contra Costa Canal is approximately 450 to 650 feet south of the project site. According to the California Department of Forestry and Fire Protection (CAL FIRE), the project site is not located in a Moderate, High, or Very High Fire Hazard State Responsibility Area. Two miles west of the project site, Briones Regional Park is designated as a High Fire Hazard Severity Zone. Given that the project site is not located on or near steep terrain surrounded by natural vegetation, is surrounded by urban uses, and does not consistently experience high winds, the project site would not be prone to wildfires. Compliance with applicable State and local plans and regulations would decrease the risk of impacts related to wildland fire hazards. Specifically, the General Plan policies incorporate requirements for fire-safe construction into the land use planning and approval process and ensure special fire protection for high-risk land uses and structures. Contra Costa County also implements the Contra Costa County Operational Area EOP, which addresses the response to emergency incidents associated with emergencies affecting Contra Costa County. Furthermore, the proposed project would be adequately served in terms of fire protection services by the Contra Costa County Fire Protection District (CCCFPD). Finally, proposed structures would be required to comply with the California Fire Code with regard to emergency access and types of building materials (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Pages 3.8-25–26). For these reasons, impacts would be less than significant. Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in a less than significant cumulative impact associated with hazards and emergency response (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-28). Findings Less than significant impact. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 27 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Facts in Support of Findings The geographic scope of the cumulative analysis related to hazards and hazardous materials is the project vicinity or roughly the western portion of the County. Cumulative development projects primarily consist of residential and commercial development. The types and sizes of development anticipated in the project area would not involve large quantities of hazardous materials or activities that transport or handle hazardous materials. Cumulative projects would be subject to the Hazardous Materials Transportation Act, California Public Resources Code, and other State and local regulations that would reduce and limit the associated risks. Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations, including the EPA, RCRA, Caltrans, and the HMP. However, cumulative projects may include demolition of existing structures that have the potential to contain hazardous building materials. Building materials may contain asbestos-containing material (ACM) and lead-based paint (LBP). To address potential release of hazardous materials, the County would assess structures and impose standard mitigation (required testing, removal, and proper disposal) to minimize release prior to any demolition. Additionally, regional, State, and federal regulations would apply to countywide development, and, for these reasons cumulative projects would result in a less than significant cumulative impact related to exposure to hazardous materials. Moreover, the proposed project’s incremental contribution would not be significant. To reduce the proposed project’s impacts to below a level of significance and ensure a less than significant contribution to cumulative impacts, the proposed project would implement MM HAZ-1a through MM HAZ-1c and comply with all applicable policies related to transport, use, and disposal of hazardous materials (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-28). However, no mitigation is necessary; the impact would be less than significant without any mitigation. The main arterial streets that would serve as the most likely evacuation routes out of the central portion of the County include I-680, SR-24, and Ygnacio Valley Road. Planned uses as proposed by the cumulative projects are contemplated in the General Plan, would result in predominantly infill development, and would not significantly increase need for emergency services, including those related to wildfires. Furthermore, all construction would adhere to the regulations included in the California Fire Code that are designed to minimize the potential for the release of hazardous materials or uncontrolled fires. Once development is proposed, the County would assess the needs for fire protection services and inform efforts to improve or expand needed facilities. Cumulative development in the County primarily consists of residential and commercial development. New residential developments would contribute to increases in the County’s population. All development would, however, comply with emergency access requirements as projects condition. Furthermore, cumulative development in the County, including the proposed project, would not result in permanent road closures, impede established emergency access routes, or interfere with emergency response requirements. Moreover, the proposed project would fully comply with all applicable regulations (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-28). Therefore, the proposed project would not have a cumulatively considerable contribution to cumulative impacts. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 28 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx 1.5.8 - Hydrology Potential Effect Impact HYD-1 The proposed project would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-14). Findings Less than significant impact. Facts in Support of Findings The proposed project is designed to comply with all local, State, and federal requirements regarding water quality, including the County’s National Pollutant Discharge Elimination System (NPDES) permits, the Contra Costa Clean Water Program (CCCWP) and the Contra Costa County Ordinance Code Chapter 1014-4, which requires the preparation and implementation of a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP includes Best Management Practices (BMPs) to ensure reduction of pollutants from construction activities potentially entering surface waters. Additionally, implementation of the SWPPP would also prevent pollutants from entering the Ygnacio Valley Basin by preventing pollutants from moving off-site. Although construction and operation of the proposed project may have the potential to generate increased sedimentation, compliance with applicable policies and regulations would minimize the potential to degrade water quality in downstream water bodies to the maximum extent possible and result in less than significant impacts. Additionally, the on-site storm drain system has been designed to meet the County’s hydraulic requirements. On-site storage facilities of 2,800 cubic feet would be needed to mitigate the potential increase of post-development flows and to meet the hydromodification requirements. To meet this requirement, two underground storage vaults are proposed to capture, store, and release the post- development storm flow into the existing off-site storm drainage facilities. These two vaults are placed at the downstream ends of the on-site storm drains at the respective discharge points at Oak Road and Jones Road. The proposed project would utilize and integrate the bioretention technique and approach to meet the Low Impact Development (LID) treatments in compliance with the requirements set forth in the County C.3 Technical Guidance. The stormwater runoff from impervious surface is directed and passed through the bioretention areas and distributed evenly along a ponding area. Stormwater runoff will percolate through the sandy loam treatment soil and eventually be captured by the under drains and discharged into the underground storm drains. Given the physical constraints and limitations of the project site, stormwater treatment would be optimized by breaking up the new and/or replaced impervious areas in small drainage management areas and using drainage swales, curb openings, and bubble ups to convey the runoff to the treatment areas in paseos, landscape pockets between walkways/buildings and the center open space area on the project site. By implementing this approach, LID bioretention treatment areas are Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 29 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx dispersed throughout the site, enabling the project to treat 100 percent of the impervious surface with the bioretention measures (Draft EIR, Section 3.9, Hydrology and Water Quality, Pages 3.9-14– 16). For the above reasons, impacts would be less than significant. Potential Effect Impact HYD-2 The proposed project would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the proposed project may impede sustainable groundwater management of the basin (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-17). Findings Less than significant impact. Facts in Support of Findings Three irrigation wells located on the project site would be decommissioned prior to redevelopment. The proposed project would increase impervious surfaces by 36,420 square feet compared to existing conditions. However, the proposed project would incorporate LID techniques as described above in the Impact HYD-1 discussion. In addition, the Contra Costa Water District would be able to provide adequate water services to the project site and the rest of its service area during normal, dry, and multiple dry years, and no groundwater would be used. Thus, the project would not interfere substantially with groundwater supply, recharge, or groundwater management and impacts would be less than significant (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-17). Potential Effect Impact HYD-4 The proposed project would not be located in a flood hazard zone, tsunami, or seiche zone, or risk release of pollutants due to project inundation (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-22). Findings Less than significant impact. Facts in Support of Findings The Federal Emergency Management Agency (FEMA) designates the project site Zone X—area of minimal flood hazard. The closest designated 100-year flood hazard zone to the project site is Walnut Creek, located approximately 0.46 mile to the east. Therefore, the project site is not located within a recognized flood hazard area. The project site is not located near the ocean and as such would not be susceptible to inundation from a tsunami. The project site is not located near a large, enclosed body of water and as such would not be susceptible to inundation from a seiche. As a result, the project site would not be a risk for inundation from flooding, tsunami, or seiche and impacts are less than significant (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-22).

Findings Less than significant impact. Facts in Support of Findings The proposed project would not conflict with the County Watershed Program and the County’s NPDES program. The proposed project would be required to comply with the terms of the Construction General Permit, which require the preparation and implementation of an SWPPP that includes BMPs to ensure reduction of pollutants from construction activities potentially entering surface or groundwater. The project site has little potential for groundwater recharge due to shallow groundwater levels. In addition, the Contra Costa Water District would provide potable water to the project site and the project would not use groundwater as a water source. As a result, the project would not conflict with or obstruct a sustainable groundwater management plan (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-22). Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned ,and approved projects, would result in a less than significant cumulative impact related to hydrology, surface water quality, and groundwater quality (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-24). Findings Less than significant impact. Facts in Support of Findings Hydrology Cumulative impacts related to hydrology and water quality typically occur within a defined watershed. All properties on the cumulative projects list in Table 3-1 of the Draft EIR are located within the Walnut Creek Watershed, and all respective surface water in the watershed eventually discharges into Suisun Bay. Some cumulative projects are located within Contra Costa County, including the project, and would be required to comply with the CCCWP and Contra Costa County General Plan policies, which prevent a project from increasing off-site surface water flow from existing conditions and ensure that projects adhere to best practices during construction to prevent pollutants from being carried off-site. Some cumulative projects are located in the cities of Walnut Creek and Pleasant Hill. Cumulative development in the City of Walnut Creek would be required to demonstrate consistency with the City of Walnut Creek General Plan and applicable codes, ordinances, and policies related to preventing pollutants from being conveyed off-site. Cumulative development in the City of Pleasant Hill would be required to demonstrate consistency with the City Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 31 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx of Pleasant Hill General Plan and applicable codes, ordinances, and policies related to preventing pollutants from being conveyed off-site. The combination of these policies and best practices would prevent significant cumulative impacts to hydrology (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-23). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project would not have a significant incremental contribution to cumulative impacts. To ensure a less than significant contribution to cumulative impacts, the proposed project will be required to implement all applicable policies and best practices, as described in Section 3.9, Hydrology and Water Quality, during the design review process. Therefore, the proposed project’s contribution to cumulative impacts would be considered less than significant. Water Quality The geographic context for consideration of cumulative impacts related to surface water quality is the Walnut Creek Watershed. All cumulative projects, including the project, would involve short- term construction and long-term operational activities that would have the potential to degrade water quality in downstream water bodies, including Walnut Creek and Suisun Bay. All cumulative project construction would be required to obtain a Construction General Permit from the California State Water Resources Control Board (State Water Board), which would require preparation of a SWPPP that would control potential discharges of contaminants into Walnut Creek and Suisun Bay. Operations of these cumulative projects would be required to comply with the CCCWP, County Ordinance Code regarding stormwater, or the cities of Walnut Creek and Pleasant Hill applicable codes, ordinances, and policies related to water quality. Development in the County would be required to implement similar measures in accordance with adopted regulations, while projects would be subject to the Construction General Permit if applicable. Development in the City of Walnut Creek would be required to implement similar measures in accordance with adopted regulations, while projects would be subject to the Construction General Permit if applicable. Development in the City of Pleasant Hill would be required to implement similar measures in accordance with adopted regulations while projects would be subject to the Construction General Permit if applicable (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-23). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project’s compliance with the requirements identified above would ensure that the proposed project would not have a significant incremental contribution to cumulative impacts. The geographic context for consideration of cumulative impacts related to groundwater quality and management is the Ygnacio Valley Groundwater Basin. All cumulative projects, including the proposed project, would involve short-term construction and long-term operational activities that would have the potential to impact groundwater quality and management. All cumulative project construction would be required to obtain a Construction General Permit from the State Water Board, which would require preparation of a SWPPP that would control pollutants that could seep into groundwater. Operations of cumulative projects in Contra Costa County would be required to comply with the CCCWP and the County Ordinance Code regarding groundwater. Operations of cumulative projects in Walnut Creek would be required to comply with the CCCWP and the City of Walnut Creek Ordinance Code regarding groundwater. Operations of cumulative projects in Pleasant Hill would be required to comply with the CCCWP and the City of Pleasant Hill Ordinance Code regarding Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 32 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx groundwater (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-24). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project’s compliance with the requirements identified above would ensure that the proposed project would not have a significant incremental contribution to cumulative impacts. 1.5.9 - Land Use and Planning Potential Effect Impact LAND-1 The proposed project would not physically divide an established community (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-15). Findings Less than significant impact. Facts in Support of Findings The development of the proposed townhouse condominium buildings would not impair access to any established community, impede travel or otherwise constitute division of an established community. Rather, the proposed project would establish connectivity and pedestrian access between Jones Road and Oak Road by providing private street and walkable landscaped open space (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-16). Potential Effect Impact LAND-2 The proposed project would not cause a significant environmental impact due to conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-16). Findings Less than significant impact. Facts in Support of Findings Strict conformity with all aspects of a general plan is not required. A lead agency can find a proposed project consistent with its local general plan if the project furthers one or more policies and does not obstruct other policies. Perfect conformity with every plan policy is not required. Consistency of the proposed project with applicable General Plan policies is evaluated in Table 3.10-5 on Page 3.10-17 through Page 3.10-27 of the Draft EIR. The General Plan designates the project site as MH, which allows for densities between 22.0 and 29.9 multiple-family units per net acre. The proposed project would develop 125 townhouse condominiums, resulting in a total of 237,816 square feet of net new habitable construction on 5.94 acres or a net density of 26.3 dwelling unit per acre. Therefore, the density and use would be consistent with the General Plan land use designation. The proposed project would be consistent with the General Plan goals and policies relative to providing residences in unincorporated area of the County. The project site is currently zoned R-15, M-17, and M-29. The proposed project would rezone the entire site to P-1 to allow flexibility with respect to use, building types, lot size, and open space while Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 33 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx ensuring the proposed project complies with the General Plan and requirements as set forth in the Ordinance Code. The proposed rezone is intended to achieve project consistency with the Contra Costa County Zoning Ordinance. Additionally, the proposed project would be consistent with County parking standards and with Ordinance Code Section 82-16.412, which sets forth the amounts of bicycle parking that a project must provide. Overall, the proposed project is consistent with the General Plan and would not conflict with applicable land use plans, policies, or regulations of the General Plan or the Ordinance Code that were adopted for the purpose of avoiding or mitigating an environmental effect (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-16). Accordingly, impacts are less than significant. Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in a less than significant cumulative impact related to land use and planning (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-29). Findings Less than significant impact. Facts in Support of Findings The geographic scope of the cumulative land use analysis is the unincorporated area of Contra Costa County with a focus on the area surrounding the project site. Land use decisions for both the proposed project and for some of the other cumulative projects are made at the County level. Some cumulative projects are located in the cities of Walnut Creek and Pleasant Hill, and land use decisions for those projects are made at the relevant city level. Development within the unincorporated County is governed by the General Plan and the Ordinance Code, which ensure logical and orderly development and require discretionary review to ensure that projects do not result in environmental impacts due to inconsistency with the General Plan and other land use planning regulations. This would minimize any cumulative impact related to division of an established community. Development within the unincorporated County would be required to demonstrate consistency with the General Plan and applicable codes, ordinances, and policies. Development in the City of Walnut Creek would be required to demonstrate consistency with the City of Walnut Creek General Plan and applicable codes, ordinances, and policies. Development in the City of Pleasant Hill would be required to demonstrate consistency with the City of Pleasant Hill General Plan and applicable codes, ordinances, and policies. This would ensure that these cumulative projects comply with applicable planning regulations (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-28–29). As such, development is not likely to create significant land use conflicts or divide existing communities. For these reasons cumulative impacts with respect to land use would be less than significant. The proposed project’s incremental contribution to cumulative land use impacts would also not be significant. As discussed under Impacts LAND-1 and LAND-2, implementation of the proposed project would not physically divide an established community or conflict with any land use plan, Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 34 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx policy, or regulation, adopted for the purpose of avoiding or mitigating an environmental effect. Accordingly, the proposed project ’s contribution to cumulative impacts would also be less than significant. 1.5.10 - Noise Potential Effect Impact NOI-3 The proposed project would not result in generation of excessive groundborne vibration or groundborne noise levels (Draft EIR, Section 3.11, Noise, Page 3.11- 18–21). Findings Less than significant impact. Facts in Support of Findings Contra Costa County has not adopted criteria for construction or operational groundborne vibration impacts. Therefore, the Federal Transit Administration (FTA ) construction vibration impact criteria are utilized. The FTA threshold of 0.2 inches per second (in/sec) peak particle velocity (PPV) is the potential damage criteria threshold for buildings of non-engineered timber and masonry construction. For operational impacts, a significant impact will occur if project ongoing activities would produce groundborne vibrations that are perceptible without instruments by a reasonable person at the property lines of the site. Impact equipment, such as pile drivers, are not expected to be used during construction of the project. Therefore, of the variety of equipment used during construction of the project, the small vibratory rollers that would be used in the site preparation phase of construction would produce the greatest groundborne vibration levels. Small vibratory rollers produce groundborne vibration levels ranging up to 0.101 in/sec PPV at 25 feet from the operating equipment. The nearest off-site receptor to where the heaviest construction equipment would operate are the multi-family residential homes, approximately 20 feet south of the nearest construction footprint for the project. As measured at the nearest receptor, operation of a small vibratory roller could result in groundborne vibration levels up to 0.141 in/sec PPV. This is below the FTA’s damage threshold criteria of 0.2 in/sec PPV for non-engineered timber and masonry buildings. Implementation of the project would not include any permanent sources of vibration that would expose persons in the project vicinity to groundborne vibration levels that could be perceptible without instruments at any existing sensitive land use in the vicinity of the project site (Draft EIR, Section 3.11, Noise, Page 3.11-21–22). Potential Effect Impact NOI-4 The proposed project would not expose people residing or working in the project area to excessive noise levels for a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport (Draft EIR, Section 3.11, Noise, Page 3.11-22). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 35 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Findings No impact. Facts in Support of Findings The project site is not located within the vicinity of a private airstrip. The nearest public airport to the project site is the Buchanan Field Airport, located approximately 4.5 miles north of the project site. According to the airport’s noise contour map, the project site is located outside of the 65 A- weighted decibels (dBA) Community Noise Equivalent Levels (CNEL) airport noise contours. While aircraft noise is occasionally audible on the project site from aircraft flyovers, aircraft noise associated with nearby airport activity would not expose people to residing or working near the project site to excessive noise levels. Therefore, implementation of the project would not expose persons residing or working in the project vicinity to noise levels from airport activity that would be in excess of normally acceptable standards for the proposed land use development (Draft EIR, Section 3.11, Noise, Page 3.11-22). 1.5.11 - Population and Housing Potential Effect Impact POP-1 The proposed project would not induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure) (Draft EIR, Section 3.12, Population and Housing, Page 3.12-8). Findings Less than significant impact. Facts in Support of Findings The proposed project would add an estimated 357 persons to the County’s population. This would represent an increase of 0.2 percent relative to the unincorporated population of 174,423. This amount of population growth would be within the General Plan’s 2020 population and dwelling projections for the unincorporated area and, therefore, would not be considered substantial. Furthermore, it would also be within ABAG’s 2020-2040 regional population growth projections. The proposed project is exclusively residential; it would not create new permanent employment opportunities. Thus, no indirect population growth from new employment would occur. The project site has been developed since the 1930s and is located within an urbanized area of the unincorporated County. It is served with urban infrastructure and utilities including potable water, sewer, storm drainage, electricity, and natural gas. As such, the proposed project would not remove a barrier of growth through the extension of infrastructure or utilities to an unserved area. Impacts would be less than significant. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 36 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Potential Effect Impact POP-2 The proposed project would not displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere (Draft EIR, Section 3.12, Population and Housing, Page 3.12-9). Findings No impact. Facts in Support of Findings Impacts related to displacement of people or housing necessitating replacement housing are limited to operational impacts. No respective construction impacts would occur. The site contains two existing residential units that are occupied by the property owners’ family members serving as caretaker and security for the property and existing improvements. Removal of these existing uses would not result in the displacement of substantial numbers of persons or housing (Draft EIR, Section 3.12, Population and Housing, Page 3.12-9). Potential Effect Cumulative Impact Cumulative impacts associated with the proposed project, in conjunction with other past, present, planned, and approved projects, related to population growth, both direct and indirect, as well as population and housing displacement, would be considered less than significant (Draft EIR, Section 3.12, Population and Housing, Page 3.12-9). Findings Less than significant impact. Facts in Support of Findings The geographic scope of the cumulative population and housing analysis is Contra Costa County. As of 2021, the County was estimated to have a population of 1,153,854, with unincorporated areas having a population of 174,423. Cumulative projects in conjunction with the proposed project would add residential units and population to the County. None of the listed projects would substantially displace housing units or people within the County. In fact, implementation of the cumulative projects would result in a net increase of housing in the County. The County further requires development that may impact housing to include affordable housing units or pay a related impact fee (see Regulatory Setting). Therefore, cumulative impacts associated with population and housing displacement would be less than significant (Draft EIR, Section 3.12, Population and Housing, Page 3.12-9). The proposed project would add 357 persons to the County’s population, which would represent growth of less than 0.01 percent of the County’s population and 0.02 of the unincorporated population. As such, there would not be substantial direct population growth associated with the proposed project in conjunction with the cumulative projects.

Therefore, cumulative impacts would be no impact. 1.5.12 - Public Services and Recreation Potential Effect Impact PUB-1 The proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered fire protection facilities, need for new or physically altered fire protection facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for fire protection (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-17). Findings Less than significant impact. Facts in Support of Findings Four fire stations are located within approximately 2 miles of driving distance of the project site: Station No. 1, located at 1330 Civic Drive in Walnut Creek, is approximately 1.7 miles (driving distance) south of the project site; Station No. 2, located at 2012 Geary Road in Pleasant Hill, is approximately 1.4 miles (driving distance) west of project site, Station No. 5, located 205 Boyd Road in Pleasant Hill, is approximately 1.9 miles (driving distance) north of the project site; and Station No. 10, located at 2955 Treat Boulevard in Concord, is approximately 2.2 miles (driving distance) northeast of the project site. Using an average travel speed of 35 miles per hour (mph), a fire engine would be able to reach construction areas at the project site from Station No. 2 (approximately 1.4 miles of driving distance) in 2 minutes and 24 seconds, which is under the 5-minute response standard set by the County General Plan. As part of project construction, the proposed project would comply with the CBC, which is adopted by the Ordinance Code. In compliance with the California Fire Code, Part 9 of the CBC, during construction the proposed project would follow standards for fire safety related to provision of fire apparatus access and acquisition of building permits. Specifically, CBC Section 105.7.17 requires plans be submitted and a permit is required to install, improve, modify, or remove public or private roadways, driveways, and bridges for which Fire District access is required by the Fire Code; this would ensure adequate driveway/entry turning radius, height clearance, and fire hydrant access for fire trucks and engines at the project site during construction. In addition, CBC Section 105.7.18 requires plans be submitted to the Fire Code Official for all land developments or for the construction, alteration, or renovation of a building within the jurisdiction where a building permit is required; this would ensure that construction and alteration would not obstruct CCCFPD from delivering adequate levels of fire protection services. With an adequate fire engine response time to the project site and adherence to the aforementioned CBC Code sections, construction of the proposed project would not create the need for new or altered fire protection facilities (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-17). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 38 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx The operation of new townhouses on the project site would result in new residents at the project site and could in turn result in an increase in calls for fire protection and emergency medical services. As noted above, Fire Station No. 2, at 2012 Geary Road, is approximately 1.4 miles west of the project site, and could reach the site within 2 minutes and 24 seconds, which is below the 5- minute response standard set by the General Plan. As part of project operation, the proposed project would comply with the CBC, which is adopted by the Ordinance Code. Specifically, in compliance with the California Fire Code, Part 9 of the CBC, during operation the proposed project would follow standards for fire safety such as fire flow requirements for buildings, fire hydrant location and distribution criteria, automated sprinkler systems, and fire-resistant building materials. Primary vehicle access to the project site would be from a driveway on Oak Road and a driveway on Jones Road. Oak Road is a public local street under the jurisdiction of the City of Walnut Creek. It runs north–south along the project site east frontage. Jones Road is a public County local street that runs along the project site west frontage. Thus, during project operation, emergency vehicles would not have difficulty accessing the project site. As such, it is not expected that the proposed project would adversely affect response times or increase the use of existing fire protection or emergency medical response facilities such that substantial physical deterioration, alteration, or expansion of these facilities would be required, thereby triggering environmental impacts. Furthermore, the project applicant would be required to pay applicable fees toward fire protection facilities and apparatus so that the CCCFPD can maintain fire safety standards. With an adequate fire engine response time to the project site, adherence to the aforementioned CBC Code sections, adequate project site access, and payment of impact fees to the CCCFPD, operation of proposed project would not create a need to construct new or expand existing fire protection or emergency medical services facilities (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-18). Potential Effect Impact PUB-2 The proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered police protection facilities, need for new or physically altered police protection facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for police protection (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-18). Findings Less than significant impact. Facts in Support of Findings The nearest Sheriff station to the project site is the Valley Station at 150 Alamo Plaza Unit C, located 6.7 miles (driving distance) southeast of the project site; however, response is likely to originate from Sheriff Deputies or Walnut Creek police officers pursuant to mutual aid patrolling the local beat. If response calls originated from the Valley Station, response would be approximately 11 minutes and 29 seconds to the project site, assuming an average travel speed of 35 mph driving speed. During construction, the proposed project would also implement security measures such as provision of a Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 39 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx project-boundary fence to prohibit access to persons other than construction personnel. With an adequate police response time to the project site and provision of adequate security measures, construction of the proposed project would not create the need for new or altered police protection facilities. The operation of new townhouses on the project site would result in new residents at the project site and could in turn result in an increase in calls for police protection services. The Office of the Sheriff does not set a specific goal for emergency call response times. However, County General Plan Policy 7-59 indicates that when making staffing and beat configuration decisions, the Sheriff should strive for a maximum response time for Priority 1 or 2 calls of 5 minutes for 90 percent of all emergency responses in central business district, urban, and suburban areas. This General Plan Policy indicated response time is a goal, not a requirement. The proposed project would increase the population of unincorporated Contra Costa County by approximately 357 persons. Accordingly, the proposed project would require 55 square feet of Sheriff station space. This increased demand for Sheriff station space represents approximately 1 percent of the Valley Station’s existing square footage and, thus, represents a nominal increase in demand. The Office of the Sheriff did not indicate that the proposed project would result in the need for new or expanded Sheriff facilities in order to maintain acceptable service ratios, response times, or other performance objectives. Furthermore, the project applicant would be required to pay applicable fees to the Office of the Sheriff to help provide for the costs associated with a police facilities building and equipment to serve additional demands for police services. With adequate project site access and payment of impact fees to the Office of the Sheriff, operation of the proposed project would not create a need to construct new or expand existing police protection facilities (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-19–20). Potential Effect Impact PUB-3 The proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered school facilities, need for new or physically altered school facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios or other performance objectives for schools (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-20). Findings Less than significant impact. Facts in Support of Findings The project applicant would be required to pay development impact fees to the Walnut Creek School District (WCSD) and Acalanes Union High School District (AUHSD). Pursuant to Government Code Section 65995, payment of adopted development fees is considered “full and complete mitigation” for impacts to school facilities and local governments are prohibited from assessing additional fees or exactions for school impacts. With payment of impact fees to the WCSD and AUHSD, operation of the proposed project would not create a need to construct new or expand existing school facilities (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-21).

Findings Less than significant impact. Facts in Support of Findings Impacts related to provision of and need for construction of new or expanded library facilities are limited to operational impacts. The General Plan does not include a standard or goal for the provision of library services; however, for informational purposes, the County generally provides approximately 319 gross square feet of library space per 1,000 residents. The proposed project’s approximately 357 residents is a nominal increase compared with the existing County population of approximately 1.1 million residents served by the Contra Costa County Library system. The proposed project’s estimated increase in persons would represent an increase of less than 1 percent relative to the existing residents served by the Contra Costa County Library system. As such, the County’s provision of library space per 1,000 residents would not be affected by implementation of the proposed project. Furthermore, the County Librarian anticipates that the proposed project would not have a noticeable effect on the ability of the County Library system to provide library services. With adequate relevant library system capacity, operation of proposed project would not create a need to construct new or expand existing library facilities (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-22). Potential Effect Impact REC-1 The proposed project would not increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-22). Findings Less than significant impact. Facts in Support of Findings Impacts related to increased use of existing parks and recreational facilities are limited to operational impacts. Goal 9-K of the General Plan Open Space Element seeks to achieve a level of park facilities equal to 4 acres per 1,000 population or 0.004-acre per person. With a County population of 1,153,854 persons (2021) and approximately 46,624 acres of parks (State, County, East Bay Regional Park District [EBRPD], and local parks), the current ratio is approximately 40.4 acres per 1,000 population, far exceeding the County’s goal. The proposed 125 residential units would be Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 41 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx expected to result in a permanent population of 357 persons, resulting in the need for 1.428 acres of parkland to assist in the County’s parkland goal. Nearby recreational facilities total nearly 7,000 acres in available existing parks. Given the wide range of proposed on-site and existing proximate parks and recreational facilities available to project-related residents, the recreational needs of the proposed project’s anticipated 357 new residents would be dispersed across these nearly 7,000 total acres of parkland and, thus, not result in an increased use that would cause substantial physical deterioration of existing neighborhood and regional parks or other recreational facilities. Additionally, the proposed project is subject to the County’s Park Impact Fee. The Park Impact Fees would be collected to fund the acquisition and development of parks in Contra Costa County to serve unincorporated County residents in lieu of providing the required acreage on the project site (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-23). Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in less than significant cumulative impacts related to public services and recreation (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-27). Findings Less than significant impact. Facts in Support of Findings Cumulative development could increase population within the proposed project vicinity by approximately 2,910 persons. The proposed project would add an estimated 357 persons to the County’s population (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-24). Fire Protection Facilities The cumulative increase in population could result in an increased demand for fire protection facilities. To help offset the increased demand, the cumulative projects would be required to pay all applicable fees to the CCCFPD. All developments would also adhere to the California Fire Code, Part 9 of the CBC in terms of meeting standards for fire safety such as fire flow requirements for buildings, fire hydrant location and distribution criteria, automated sprinkler systems, and fire- resistant building materials. With adherence to CBC sections and payment of applicable fees, cumulative projects would not result in need for new or altered fire protection or emergency medical facilities. All cumulative projects would be required to comply with city and county ordinances and General Plan policies that address fire protection services. Therefore, cumulative impacts would be less than significant. Moreover, the proposed project’s incremental contribution to less than significant cumulative impacts would not be significant. As discussed under Impact PUB-1, implementation of the proposed project would not create a need for new or physically altered facilities to provide fire protection services to the service area. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 42 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Police Protection Facilities The cumulative increase in population could result in an increased demand for police protection facilities. To help offset the increased demand for police protection facilities, the cumulative projects would be required to pay applicable fees to the Office of the Sheriff. All developments would also be reviewed for impacts on law enforcement services and would be required to address any potential impacts with mitigation. Because demand for law enforcement services is highly dependent on a number of factors that vary substantially by project (clientele, hours of operation, crime prevention measures, etc.), it is unlikely that there would be substantial overlap in demand that would result in a cumulatively significant impact such that new police protection facilities are necessary (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-25). All cumulative projects would be required to comply with city ordinances and General Plan policies that address police protection services. Therefore, cumulative impacts would be less than significant. Moreover, the proposed project’s incremental contribution to less than significant cumulative impacts would not be significant. As discussed under Impact PUB-2, implementation of the proposed project would not create a need for new or physically altered facilities to provide fire protection services to the service area. School Facilities The cumulative increase in population could result in an increased demand for school facilities. Other cumulative projects do not include any educational facilities. All cumulative developments would be required to pay development impact fees impact fees toward the two applicable school districts. Under State law, this is the exclusive means of mitigating impacts to school facilities due to increased enrollment. As part of the project entitlement process, the cumulative project applicants would be responsible for paying their fair share of these school facility fees. The payment of school impact fees would ensure that school facilities can accommodate future students. Therefore, cumulative impacts would be less than significant. As discussed in impact PUB-3 the proposed project will be required to pay school impact fees and this requirement is considered to fully mitigate impacts on school facilities. Therefore, impacts of the General Plan on school facilities are not cumulatively considerable. Library Facilities The cumulative increase in population could in turn result in an increased demand for library facilities. The County generally provides approximately 319 gross square feet of library space per 1,000 residents. With development of the other cumulative project in conjunction with the proposed project, the County’s provision of library space per 1,000 residents would need to be increased by approximately 1,042 square feet. The construction of the new Pleasant Hill Library (scheduled to be completed in 2022) would more than adequately address this need. Therefore, cumulative impacts are less than significant (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-26). The proposed project’s incremental contribution to less than significant cumulative impacts would not be significant. The proposed project would result in growth of less than 0.01 percent of the County’s population and 0.02 of the unincorporated population, which would not significantly increase demand for library services. For these reasons, impacts on library facilities are not cumulatively considerable and the cumulative impact would be less than significant.

To help offset that demand, Cumulative Project 1, listed in Table 3-1 of the Draft EIR, would be subject to the County Park Impact Fee. The Park Impact Fees would be collected to fund the acquisition and development of parks in Contra Costa County to serve unincorporated County residents in lieu of providing the required acreage on the project site. Other cumulative projects that are within the City of Walnut Creek and City of Pleasant Hill would similarly be required to provide parkland or pay development fees. With payment of Park Impact Fees by the cumulative projects, there would be a less than significant cumulative impact related to potential increased use and physical deterioration of existing parks and recreational facilities. The California Department of Parks and Recreation (DPR), EBRPD, Contra Costa County, and cities in the proposed project vicinity maintain State, regional, and local community parks, trails, and recreational facilities for public use throughout Contra Costa County. County park standards are established in the County’s General Plan. Specifically, Goal 9-K of the General Plan Open Space Element, seeks to achieve a level of park facilities equal to 4 acres per 1,000 population or 0.004- acre per person. With a County population of 1,153,854 persons (2021) and approximately 46,624 acres of parks (State, County, various cities, and EBRPD), the current ratio is approximately 40.4 acres per 1,000 population, far exceeding the County goal. The cumulative projects would add approximately 2,910 residents to the area. However, the current high ratio of parks to population would not be significantly impacted by the added residents (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-26). Therefore, the proposed project’s impacts on park and recreation facilities are not cumulatively considerable and the cumulative impact would be less than significant. 1.5.13 - Transportation Potential Effect Impact TRANS-1 The proposed project would not conflict with a program plan, ordinance, or policy of the circulation system, including transit, roadway, bicycle and pedestrian facilities (Draft EIR, Section 3.14, Transportation, Page 3.14-14). Findings Less than significant impact. Facts in Support of Findings Bicycle Facilities There are no existing bike lanes on Jones Road. However, there is a pedestrian/bike trail, Iron Horse Regional Trail, located approximately 1,500 feet east of the project site. The bike trail provides access to the Pleasant Hill/Contra Costa Centre BART station. There is also another pedestrian/bike trail, Contra Costa Canal Trail, located approximately 450–600 feet south of the project site and crossing Oak Road and Jones Road. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. The project would not affect existing or planned bicycle facilities.

Oak Road has planned Class II facilities in the vicinity of the project. The planned facilities would be located on Oak Road between Treat Boulevard and the Contra Costa Canal Trail. The four on-street parking spaces proposed along Oak Road would not result in a conflict with future construction of this facility. The Iron Horse Regional Trail, a pedestrian/bike trail, is located approximately 1,500 feet east of the project site. The Iron Horse Regional Trail extends from Marsh Drive in Concord to Santa Rita Road in Pleasanton. The Iron Horse Regional Trail provides access to the Pleasant Hill/Contra Costa Centre BART station. There is also another trail, Contra Costa Canal Trail, located approximately 650 feet south of the project site and crossing Jones Road. The Contra Costa Canal Trail extends from Muir Road in Martinez to Willow Pass Road in Concord. The Contra Costa Canal Trail provides access to Walden Park and the Iron Horse Regional Trail. The Contra Costa Canal Trail also provides good bicycle connectivity to the project site and the Seven Hills School. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. Pedestrian Facilities There are sidewalks on the east side of Jones Road within the vicinity of the project site. There are also sidewalks on both sides of Oak Road and Treat Boulevard so that residents at the project site can easily walk to the Pleasant Hill/Contra Costa Centre BART station. The traffic signals at the Oak Road/Jones Road and Oak Road/Treat Boulevard intersections include crosswalks with pedestrian signal heads to facilitate crossing the street. The Iron Horse Regional Trail and Contra Costa Canal Trial described previously are Class I pedestrian/bicycle facilities within project proximity. There are no pedestrian improvement plans along Jones Road or Oak Road along the project frontage, and the project would not affect existing or planned pedestrian facilities. The Seven Hills School is located within a 1-mile radius of the project site, and the Contra Costa Canal Trail provides a pedestrian connection to the school from the project site. Transit Facilities The site is served by several County Connection bus routes: 7, 9, 11, 14, 15, and 311. The project site is located with 0.5 mile of a major transit stop, the Pleasant Hill/Contra Costa Centre BART station, which is located north of the project site. The closest bus stop to the project site is located at Oak Road and Walden Park, approximately 970 feet south of the project site. There are sidewalks on Oak Road that provide connectivity to the bus stop. The Pleasant Hill/Contra Costa Centre BART station also provides other bus route connections in addition to other County Connection lines. AC Transit, Solano Express, FAST, and Wheels Express provide connecting transit routes at the Pleasant Hill/Contra Costa Centre BART station (refer to Exhibit 3.14-5 and Table 3.14-6). Paratransit services could also be provided to the residents at the project site. County Connection LINK serves Pleasant Hill, Walnut Creek, Concord, Lafayette, and other central Contra Costa cities. Paratransit service rides are provided within 1.5 miles of a bus stop or train station (Draft EIR, Section 3.14, Transportation, Page 3.14-15).

Findings Less than significant impact. Facts in Support of Findings In accordance with new CEQA Guidelines, the County has transitioned from intersection Level of Service (LOS) to VMT for CEQA transportation analysis. The Contra Costa County Transportation Analysis Guidelines (County TAG ) also include screening criteria for projects that are expected to result in less than significant VMT impacts. According to the County TAG, a project is expected to result in a less than significant VMT impact if the proposed project is located within 0.5 mile of an existing major transit stop or an existing stop along a high-quality transit corridor. The Pleasant Hill/Contra Costa Centre BART station is located within 0.5 mile of the project site. In addition, there are bicycle and pedestrian facilities between the project site and the Pleasant Hill/Contra Costa Centre BART station, such as continuous sidewalks along Jones Road and Oak Road that connects to the project site to this BART station. At a normal walking pace, it would take approximately 5 minutes to walk from the project site to this BART station (Draft EIR, Section 3.14, Transportation, Page 3.14-17). The Iron Horse Regional Trail and the Contra Costa Canal Trail also provide access to the Pleasant Hill/Contra Costa Centre BART station. There are also bike racks and bike lockers at the BART station for bicyclists to park their bicycles. Furthermore, the BART system provides quality regional connection to major employment destinations within the Bay Area (i.e., Oakland, San Francisco) and will soon connect to the San José area as well. The Pleasant Hill/Contra Costa Centre BART station also connects to local bus routes that are provided by County Connection. These local bus routes include County Connection weekday routes 7, 9, 11, 14, 15, and 18, County Connection weekend routes 311 and 316, County Connection Early Bird Express routes 702 and 712, Solano Express Blue and Yellow lines, FAST Blue line, Wheels Bus line 70X, and Alameda-Contra Costa Transit District (AC Transit) route 702. The regional transit connectivity available to the project residents, along with availability of bicycle parking on-site and bicycle and pedestrian facilities in the vicinity of the project site, would reduce residents’ need to drive (Draft EIR, Section 3.14, Transportation, Page 3.14-18). Potential Effect Impact TRANS-3 The proposed project would not substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment) (Draft EIR, Section 3.14, Transportation, Page 3.14-18). Findings Less than significant impact.

There would also be a driveway that would connect to the project site on Oak Road. The new driveways on Jones Road and Oak Road would be 26 feet wide, which could accommodate two-way traffic and meet Fire Code standards (Draft EIR, Section 3.14, Transportation, Page 3.14-19). The project access points would remain free and clear of any obstructions that would materially and adversely affect sight distance, thereby ensuring that exiting vehicles can see pedestrians on the sidewalk and other vehicles traveling on adjacent roadways. As designed, landscaping and parking would not conflict with a driver’s ability to locate a gap in traffic and see oncoming pedestrians and bicyclists. Adequate corner sight distance (sight distance triangles) would be provided at all site access points in accordance with the County standards. The line of sight for vehicles exiting the driveway and vehicles traveling northbound on Jones Road are clear and visible. Vehicles exiting the driveway would be visible to the vehicles traveling southbound on Jones Road and Oak Road. There are existing red curbs on both sides of each driveway to provide adequate visibility for vehicles exiting the project site. The proposed project would not substantially increase hazards due to any design features. The proposed project would provide new streets and alleys within the project site that lead to each unit. Each unit would have its own driveway and a garage. According to the Ordinance Code, the minimum two-way drive aisle width for multi-family uses is 20 feet and 26 feet when portion of the building has human occupancy located more than 30 feet above the access road. The site plan shows the appropriate drive aisle widths within the project site. The site plan demonstrates the proposed project would provide adequate space for garbage trucks, loading trucks and emergency vehicles to circulate throughout the project site (Draft EIR, Section 3.14, Transportation, Page 3.14-19). Potential Effect Impact TRANS-4 The proposed project would not result in inadequate emergency access (Draft EIR, Section 3.14, Transportation, Page 3.14-19). Findings Less than significant impact. Facts in Support of Findings Emergency vehicle access would be provided via the two proposed driveways on Jones Road and Oak Road. The new driveways would be 26 feet wide, which can accommodate two-way traffic and provide adequate access for emergency vehicles (Draft EIR, Section 3.14, Transportation, Page 3.14- 19). Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in less than significant cumulative impacts related to transportation (Draft EIR, Section 3.14, Transportation, Page 3.14-20). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 47 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Findings Less than significant impact. Facts in Support of Findings The geographic scope of the cumulative transportation analysis is the roadway network and the transit, pedestrian, and bicycle facilities in the vicinity of the project site. All cumulative projects would be required to comply with County and local ordinances and General Plan policies that address potential impacts related to transportation. For these reasons, cumulative impacts with respect to transportation and traffic would be less than significant. Moreover, the proposed project’s incremental contribution to cumulative traffic impacts would not be significant. As discussed in impacts TRANS-1 through TRANS-4, the proposed project would have a less than significant impact on intersection operations, public transit, bicycles, and pedestrians. Therefore, the proposed project would not have a cumulatively considerable contribution. The proposed project’s VMT would not result in a significant impact for VMT and therefore would not have a considerable cumulative contribution. The proposed project would implement recommended TDM measures that would facilitate further reductions in VMT by encouraging use of alternate transportation modes. The proposed project’s VMT would not result in a significant impact for VMT and therefore would not have a considerable cumulative contribution. The proposed project would provide adequate emergency access via the two proposed driveways on Jones Road and Oak Road and impacts would be less than significant. Therefore, the proposed project would not have a cumulatively considerable contribution to cumulative impacts (Draft EIR, Section 3.14, Transportation, Page 3.14-20). 1.5.14 - Utilities and Service Systems Potential Effect Impact UTIL-1 The proposed project would not require or result in the relocation or construction of new or expanded water, wastewater treatment or stormwater drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-18). Findings Less than significant impact. Facts in Support of Findings Water Because the project site is currently served by the Contra Costa Water District (CCWD), its water consumption is factored into the Urban Water Management Plan (UWMP’s) planning projections. Thus, adequate water supplies are available to serve the proposed project and no new or expanded water treatment or conveyance facilities would be required. Additionally, the CCWD provided a letter to the applicant dated November 10, 2020, confirming it could serve the proposed project and providing standard requirements for new service connections (e.g., separate metering of domestic, fire, and irrigation). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 48 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Wastewater Treatment The proposed project would install a new on-site sewer collection system consisting of 8-inch diameter pipes that would discharge via service lateral to an existing 18-inch diameter sewer line in Jones Road. Central Contra Costa Sanitary District (Central San) provided comments to the applicant dated August 4, 2020, confirming it could serve the proposed project providing standard requirements for new service connections (e.g., payment of connection fees). Central San would contain sufficient capacity to serve all aspects of the project, and a new or expanded wastewater treatment facility would not be required. Stormwater Drainage There would be a net increase of 40,136 square feet of impervious surfaces relative to existing conditions (155,600 square feet vs. 195,736 square feet). The proposed project would result in 2.2 acres of impervious surfaces draining to Oak Road and 3 acres of impervious surfaces draining to Jones Road. Thus, there would be a net decrease in drainage to Oak Road and a net increase in drainage to Jones Road. The proposed project would install an on- site storm drainage system. Inlets would capture surface runoff, where it would enter an underground piping system ranging from 12 to 18 inches in diameter that would convey stormwater to bioretention basins or hydromodification vaults. The basins and vaults would be designed to promote percolation into the soil and would release runoff into the municipal drainage system at a rate no greater than the pre-development condition of the project site. In accordance with applicable provisions of Section C.3 of the San Francisco Bay RWQCB Municipal Regional Permit (Order No. R2-2015-0049, NPDES Permit No. CAS612008) (or more recent permit) the proposed project would implement LID stormwater management methods into the on-site storm drainage system consisting of rainwater harvesting and use, infiltration, evapotranspiration, or biotreatment. Collectively, these measures would serve to slow, reduce, and meter the volume of runoff leaving the project site and ensure that downstream storm drainage facilities are not inundated with project-related stormwater (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-18–19). Electric Power Electricity services would be provided by PG&E. Existing overhead utility lines along the proposed project frontage on Oak Road and Jones Road would be relocated underground. Impacts related to energy use from electric power would be less than significant (Draft EIR, Section 3.5, Energy, Page 3.5-11). Therefore, the proposed project would not result in the relocation or construction of new or expanded electric power facilities (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15- 20). Natural Gas No gas service would be provided to the proposed project. As discussed in Section 3.5, Energy, the proposed project would not result in the use of any natural gas. Therefore, there would be no impacts related to natural gas facilities (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-20).

The proposed project would not require the construction or expansion of telecommunications facilities because it is located in an urban area that already contains sufficient telecommunications facilities (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-20). Potential Effect Impact UTIL-2 The proposed project would have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple-dry years (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-20). Findings Less than significant impact. Facts in Support of Findings Impacts related to sufficient water supplies are limited to operational impacts. The proposed project would demand a net increase of 64,843 gallons of water per day, which equates to 72.6 acre-feet per year. This amount of water represents less than 1 percent of both CCWD’s 2025 average water year supply value of 216,600 acre-feet and CCWD’s 2025 single-dry year value of 174,000 (Draft EIR, Section 3.15, Table 3.15-3: Water Consumption Estimate, Page 3.15-20). Accordingly, adequate water supplies would be available to serve the project from existing and planned supplies (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-21). Potential Effect Impact UTIL-3 The proposed project would not result in a determination by the wastewater treatment provider which serves or may serve the project that it does not have adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-21). Findings Less than significant impact. Facts in Support of Findings Impacts related to sufficient water supplies are limited to operational impacts. The proposed project would generate an estimated 23,344 gallons per day (0.024 million gallons per day [mgd]) (Draft EIR, Section 3.15, Table 3.15-4: Wastewater Generation Estimate, Page 3.15-21). This amount of wastewater represents less than 1 percent of the Central San’s treatment plant daily discharge limit of 54 mgd. Thus, no new or expanded wastewater treatment or conveyance facilities would be required and there would be adequate capacity to serve the proposed project’s projected demand in addition to the provider’s existing commitments. Furthermore, Central San provided comments to the applicant confirming it could serve the proposed project providing standard requirements for new service connections (e.g., payment of connection fees) (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-21).

Findings Less than significant impact. Facts in Support of Findings During construction, the proposed project would generate 4,480 cubic yards of construction and demolition waste. The three regional landfills have 136.2 million cubic yards of remaining capacity and, thus, can accommodate the construction solid waste generated by the proposed project. Construction and Demolition Debris Recycling practices would divert most, if not all, construction solid waste from landfills (Draft EIR, Section 3.15, Table 3.15-5: Construction and Demolition Solid Waste Generation Estimate, Page 3.15-22). During operation, the proposed project would generate 321 cubic yards of solid waste annually. The three regional landfills have 136.2 million cubic yards of remaining capacity and, thus, can accommodate the solid waste generated by the proposed project at operation (Draft EIR, Section 3.15, Table 3.15-6: Operational Solid Waste Generation Estimate, Page 3.15-23). Aluminum, glass, plastic, paper, cardboard, and organic waste are collected and diverted from the waste stream. As such, the values discussed above likely overstate the solid waste generation that would be expected to occur from the proposed project (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15- 23). Potential Effect Impact UTIL-5 The proposed project would comply with federal, State, and local statutes and regulations related to solid waste (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-23). Findings Less than significant impact. Facts in Support of Findings During construction, the proposed project would be required to comply with the County’s Ordinance Code Title 4 Division 418-2.028 related to solid waste reduction and recycling measures. These measures would ensure compliance with the Integrated Waste Management Act by ensuring project construction waste is transferred to facilities that can adequately recycle solid waste. During project operation, the proposed project would be required to comply with applicable State and local regulations related to solid waste such as the California Integrated Waste Management Act and Title 4 Chapter 418 of the Contra Costa County Ordinance Code. Adherence to the County Ordinance Code would ensure sufficient solid waste collection and transportation is available to the Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 51 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx project and would also ensure that disposal sites contain sufficient capacity through permit review and inspections and recycling programs are implemented in order to divert waste. As such, project operation would not impede the ability of the County to meet waste diversion requirements or cause the County to violate State and local statutes and regulations related to solid waste (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-24). Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in a less than significant cumulative impact related to utilities and service systems (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-25). Findings Less than significant impact. Facts in Support of Findings Water Cumulative projects are located within the CCWD service area and would create water supply demand. The CCWD 2015 UWMP determined that CCWD would be able to provide adequate water supplies to the County and cumulative projects area. The County would have adequate water supplies to serve the cumulative projects during normal and dry years. In addition, cumulative projects would be required to comply with provisions of the County Code and California Green Building Code related to water conservation. Therefore, cumulative impacts are less than significant. Moreover, the proposed project ’s incremental contribution to cumulative impacts would not be significant. The proposed project, in conjunction with identified cumulative projects in Contra Costa County, would result in a less than significant cumulative impact related to water supply and water supply facilities less than significant impact (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-24). Wastewater Central San provides wastewater collection and treatment services for contracted cities and residents and business in unincorporated County land. Central San considered the existing capacity and future demand for capacity to determine needed updates to wastewater and recycled water facilities. In the course of preparing the Comprehensive Wastewater Master Plan, Central San estimated wastewater generated from future development in the service area and forecast the needed facility upgrades. The forecast included treatment facility upgrades needed to accommodate growth in the County and maintain compliance with applicable regulatory standards for wastewater treatment and discharge. The Comprehensive Wastewater Master Plan determined that capacity exists to service the County and cumulative projects area demand with respect to wastewater treatment facilities. Therefore, cumulative impacts are less than significant. Moreover, the project’s incremental contribution to cumulative wastewater impacts would not be significant. The proposed project, in conjunction with identified cumulative projects in Contra Costa County would result in a less than significant cumulative impact related to wastewater generation and wastewater treatment facilities less than significant impact (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15- 25).

Cumulative projects predominantly consist of commercial and non-residential uses located in unincorporated Contra Costa County, the City of Walnut Creek, or the City of Pleasant Hill that generate volumes of stormwater. The proposed project may be required to construct improvements such that the storm drain line is adequate, which may include an expansion of this stormwater facility to ensure that adequate capacity is maintained. Therefore, cumulative impacts are less than significant. Moreover, the project’s incremental contribution to cumulative storm drainage impacts would not be significant. The proposed project, in conjunction with the construction of other projects, would not result in a significant cumulative impact related to stormwater generation and stormwater drainage facilities (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-25). Solid Waste Central Contra Costa County Solid Waste Authority (RecycleSmart) oversees regional waste diversion programs and contracts for the solid waste recycling collection services provided within this area of the County. Cumulative projects consist predominantly of residential uses and would generate solid waste that would increase demand on solid waste facilities to receive, process, and dispose solid waste. The three regional landfills that serve the County have a combined remaining capacity of 136.2 million cubic yards. The anticipated waste volume of cumulative projects development would be 321 cubic yards per year that represents less than 1 percent of the available capacity. Existing solid waste facilities provide sufficient capacity to serve cumulative development anticipated in the County. Therefore, cumulative impacts are less than significant. Moreover, the project’s incremental contribution to cumulative solid waste impacts would not be significant. The proposed project, in conjunction with identified cumulative projects, would result in a less than significant cumulative impact related to solid waste generation and landfill capacity (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-25). 1.5.15 - Wildfire Potential Effect Impact WILD-1 The proposed project would not substantially impair an adopted emergency response plan or emergency evacuation plan (Draft EIR, Section 3.16, Wildfire, Page 3.16-11). Findings Less than significant impact. Facts in Support of Findings The proposed project would comply with the County EOP, ensuring efficient response to emergency incidents associated with emergencies affecting the County. Furthermore, blockage of an evacuation route would not occur during project construction because the proposed project would not result in road closures to either Oak Road or Jones Road, the most likely evacuation routes from the project site. Additionally, the project site is not located in a “Fire Hazard Severity Zone” in a State Responsibility Area (SRA) or a “Very High Fire Hazard Severity Zone” in a local, State, or federal responsibility area.

The proposed project would not create a permanent increase in population unaccounted for in the General Plan that could lead to overwhelming calls for emergency services. In addition, the proposed project would be designed in accordance with the County’s standards to accommodate emergency vehicle access by providing two points of access to the project site and internal roadways that would be available to emergency vehicles. Furthermore, blockage of an evacuation route would not occur during project operation because the proposed project would not result in road closures to Oak Road or Jones Road, the most likely evacuation routes from the project site. With adherence to General Plan Policy 7-64, and Implementation Measures 7-at and 7-au, which require development fees, fire agency project review, and creation of a safe environment in case of substantial disaster, the proposed project would not conflict with the County EOP or General Plan (Draft EIR, Section 3.16, Wildfire, Page 3.16- 12). Potential Effect Impact WILD-2 The proposed project would not due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire (Draft EIR, Section 3.16, Wildfire, Page 3.16-12). Findings Less than significant impact. Facts in Support of Findings Impacts related to exposure of project occupants to pollutants concentrations from wildfire are limited to operational impacts. The project site is mostly surrounded by urbanized uses on relatively flat areas lacking in woodlands or vegetation that could provide fuel load for wildfire, or steep slopes that could cause fire to spread more rapidly. The project site is surrounded by other features that provide fuel breaks in the event of a fire, such as I-680, the Contra Costa Canal, Oak Road, and Jones Road. The closest open space area (Briones Regional Park) is located approximately 3 miles west of the project site (Draft EIR, Section 3.16, Wildfire, Page 3.16-12). The project site is not located in an SRA or Local Responsibility Area (LRA) Fire Hazard Severity Zone. The nearest Fire Hazard Severity Zone is located approximately 2 miles west of the project site (Briones Regional Park) and is designated as a High Fire Hazard Severity Zone. The BAAQMD monitors the Bay Area’s air quality at a number of stations, and the closest station to the project site is located in the City of Concord, approximately 4 miles to the northeast. The average wind speed at this station varied from month to month and ranged from 7 to 16 mph in 2020. Given that the project site is not located on or near steep terrain surrounded by natural vegetation, is mostly surrounded by urban uses, and does not consistently experience high winds, the project site would not be prone to wildfires. Compliance with applicable State and local plans and regulations would decrease the risk of impacts related to wildland fire hazards. Specifically, General Plan policies incorporate requirements for fire- Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 54 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx safe construction into the land use planning and approval process and ensure special fire protection for high-risk land uses and structures. The County also implements an EOP, which addresses response to emergency incidents affecting the County. Furthermore, the proposed project would be adequately served in terms of fire protection services by the CCCFPD. Finally, the proposed project would be required to comply with the California Fire Code regarding emergency access and types of building materials (Draft EIR, Section 3.16, Wildfire, Page 3.16-13). Potential Effect Impact WILD-3 The proposed project would not require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment (Draft EIR, Section 3.16, Wildfire, Page 3.16-13). Findings Less than significant impact. Facts in Support of Findings Impacts related to installation or maintenance of infrastructure that may exacerbate fire risk are limited to operational impacts. The proposed project would include adequate emergency access via existing roads at two access points. The project site is in an urban area surrounded by existing roadways. The proposed project would not require the installation of firebreaks because it is in an urban area surrounded by existing development with little natural vegetation. The proposed project would not require emergency water sources because potable water is currently provided by the CCWD, which has adequate water supplies available to serve the project and future development during normal, dry, and multiple dry years. New electrical power and natural gas lines on and connecting to the project site would be installed underground, minimizing potential ignition and related fire risk above ground, at the project site according to the CBC, Uniform Fire Code, and Contra Costa County General Plan Implementation Measure 7-au. Finally, off-site improvements, including frontage sidewalks, driveway curbs, and gutter improvements, would not exacerbate fire risk (Draft EIR, Section 3.16, Wildfire, Page 3.16-14). Potential Effect Impact WILD-4 The proposed project would not expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes (Draft EIR, Section 3.16, Wildfire, Page 3.16-14). Findings Less than significant impact. Facts in Support of Findings Impacts related to post-fire slope instability are limited to operational impacts. The project site is not located on or near steep slopes susceptible to landslides or downstream flooding. The project site Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 55 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx has also not been affected by previous wildfires that could have resulted in drainage changes or loss of vegetation (Draft EIR, Section 3.16, Wildfire, Page 3.16-14). Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in a less than significant cumulative impact related to wildfire (Draft EIR, Section 3.16, Wildfire, Page 3.16-15). Findings Less than significant impact. Facts in Support of Findings A combination of federal, State, and local regulations limit or minimize the potential for exposure to wildfires by reducing the amount of development in wildland urban interface areas, ensuring new development is developed according to the CBC and Uniform Fire Code, and incorporating requirements for fire-safe construction into the land use planning. Cumulative projects consist predominantly of residential and commercial development. Only one of the projects would be located in designated and High or Very High Fire Hazard Zones, and an additional project is located on the edge of a High Fire Hazard Zone. However, these projects would be in areas that are already developed and do not contain significant levels of dry fuel susceptible to ignition or significantly high average wind speeds. The cumulative projects would result in predominantly infill development and would not significantly increase emergency services beyond the existing service area. Furthermore, all cumulative project construction would adhere to the County Building Codes that are designed to minimize the potential for uncontrolled fires. Adherence to County Building Codes would ensure that California Fire Code standards ,such as automatic sprinkler systems and management of fuel loads in response to annual inspection by the Fire Department, are included in development. Once cumulative development is proposed, the County assesses the needs for fire protection services and informs efforts to improve or expand needed facilities. All development would, however, comply with emergency access requirements, such as two emergency vehicle access points, as a condition of construction. Furthermore, the cumulative projects would not result in permanent road closures impede an established emergency or evacuation access route, such as I-680, or interfere with emergency response requirements, such as fire protection response time standards established by the General Plan. As such, there would be a less than significant cumulative impact associated with wildfire hazards and emergency/evacuation response (Draft EIR, Section 3.16, Wildfire, Page 3.16- 15). The proposed project’s incremental contribution to cumulative wildfire hazard impacts would not be significant. As previously discussed, the proposed project is located in an already developed areas and would involve infill development and redevelopment. As a result, the proposed project would not contribute to or exacerbate the degree of wildland fire hazard, including secondary hazards. For this reason, and those discussed in Impacts WILD-1 through WILD-4, the proposed project’s contribution to cumulative impacts would also be less than significant.

The potentially significant impacts, and the mitigation measures that will reduce them to a less than significant level, are as follows: 1.6.1 - Aesthetics, Light, and Glare Potential Effect Impact AES-4 The proposed project could create a substantial new source of light or glare which would adversely affect day or nighttime views in the area (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-9). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-12). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM AES-4 Prepare Final Lighting Plan At least 30 days prior to applying for a building permit, the applicant shall submit for review and approval by the Department of Conservation and Development, Community Development Division a Final Lighting Plan. Exterior lighting must be directed downward and away from adjacent properties and public/private right-of-way to prevent glare or excessive light spillover. Facts in Support of Findings The proposed project would result in 125 townhouse condominiums with associated windows, as well as exterior lighting and signage. The site is surrounded by residential uses, as well as Oak Road and Jones Road, all of which contribute to the existing daytime glare and nighttime lighting of the area. The proposed project would result in the development of residential uses that would include nighttime security lighting consistent with surrounding uses. Potential sources of light associated with the proposed project would consist of typical sources of lighting associated with a residential development and from vehicles traveling to and from the project site. Exterior lighting would be located around and within the project site. Lampposts would be evenly dispersed within the project site, with safety lighting, as needed throughout the site. MM AES-4 requires exterior lighting be directed downward and away from adjacent properties and public/private right-of-way to prevent glare (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-12–13). The County finds that MM AES-4 is feasible, is adopted, and will further reduce impacts associated with aesthetics, light, and glare. Accordingly, the County finds that, pursuant to Public Resources Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 57 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Aesthetics, Light, and Glare would be less than significant with mitigation incorporated. 1.6.2 - Air Quality Potential Effect Impact AIR-2 The proposed project could result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or State ambient air quality standard (Draft EIR, Section 3.2, Air Quality, Page 3.2-43). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.2, Air Quality, Page 3.2-47). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM AIR-2 Apply Construction Best Management Practices The contractor shall implement the following enhanced Best Management Practices (BMPs): 1. During site preparation and grading, all exposed surfaces shall be watered at a frequency adequate to maintain minimum soil moisture of 12 percent. Moisture content can be verified by lab samples or moisture probe. 2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered. 3. All visible mud or dirt tracked out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. 4. All vehicle speeds on unpaved roads shall be limited to 15 miles per hour (mph). 5. All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible. Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. 6. All construction equipment shall be maintained and properly tuned in accordance with manufacturer’s specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation. 7. Post a publicly visible sign with the telephone number of the Project Manager to contact regarding dust complaints. This person shall respond and take corrective action within 48 hours. The Air District’s phone number shall also be visible to ensure compliance with applicable regulations.

All excavation, grading, and/or demolition activities shall be suspended when average wind speeds exceed 20 mph. 9. Wind breaks (e.g., trees, fences) shall be installed on the windward side(s) of actively disturbed areas of construction. Wind breaks should have at maximum 50 percent air porosity. 10. Vegetative ground cover (e.g., fast-germinating native grass seed) shall be planted in disturbed areas as soon as possible and watered appropriately until vegetation is established. 11. The simultaneous occurrence of excavation, grading, and ground-disturbing construction activities on the same area at any one time shall be limited. Activities shall be phased to reduce the amount of disturbed surfaces at any one time. 12. All trucks and equipment, including their tires, shall be washed off prior to leaving the site. 13. Site accesses to a distance of 100 feet from the paved road shall be treated with a 6-to-12-inch compacted layer of wood chips, mulch, or gravel. 14. Sandbags or other erosion control measures shall be installed to prevent silt runoff to public roadways from sites with a slope greater than 1 percent. 15. Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 2 minutes. Clear signage shall be provided for construction workers at all access points. Facts in Support of Findings Predicted construction period emissions would not exceed the Bay Area Air Quality Management District (BAAQMD) significance thresholds. Construction activities, particularly during site preparation and grading, would temporarily generate fugitive dust in the form of PM10 and PM2.5. Sources of fugitive dust would include disturbed soils at the construction site and trucks carrying uncovered loads of soils. Unless properly controlled, vehicles leaving the site would deposit mud on local streets, which could be an additional source of airborne dust after it dries. The BAAQMD CEQA Air Quality Guidelines consider these impacts to be less than significant if BMPs are implemented to reduce these emissions. For example, these BMPs would reduce fugitive dust, in part, by requiring all exposed surfaces to be watered at a frequency adequate to maintain minimum soil moisture of 12 percent, which would reduce the amount of dust on-site. Additionally, dust would be contained and reduced by requiring all haul trucks transporting soil, sand, or other loose material off-site to be covered. MM AIR-2 would require the implementation of BAAQMD-recommended BMPs to reduce fugitive dust (PM10 and PM2.5) (Draft EIR, Section 3.2, Air Quality, Page 3.2-43–46). Operational air emissions from the proposed project would be generated primarily from autos driven by future residents and guests. Evaporative emissions (e.g., reactive organic gases [ROG]) from architectural coatings and maintenance products (classified as consumer products) are typical emissions from residential projects. Operational period emissions would not exceed the BAAQMD significance thresholds, and emissions from the proposed project are anticipated to be less than the prior school use operation for all analyzed pollutants except ROG. (Draft EIR, Table 3.2-11: Operational Emissions, Page 3.2-46).

Congested intersections can result in high, localized concentrations of carbon monoxide (CO). The proposed project is estimated to generate a total of 93 AM peak-hour vehicle trips and 124 PM peak-hour vehicle trips. Conservatively assuming that all peak-hour vehicle trips generated by the proposed project would travel through the intersection of Oak Road and Treat Boulevard, the Existing Plus Project traffic volumes would be 6,109 AM peak-hour trips and 5,266 PM peak-hour trips. Therefore, the proposed project would not cause any intersections near the proposed project to experience traffic volumes of 44,000 vehicles per hour. Furthermore, the adjacent roadways are not located in an area where vertical or horizontal atmospheric mixing is substantially limited. Based on the above criteria, the proposed project would not cause an exceedance of the CO screening criteria (Draft EIR, Section 3.2, Air Quality, Page 3.2-47). The County finds that MM AIR-2 is feasible, is adopted, and will further reduce impacts associated with Air Quality. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Air Quality would be less than significant with mitigation incorporated. Potential Effect Impact AIR-3 The proposed project could expose sensitive receptors to substantial pollutant concentrations. (Draft EIR, Section 3.2, Air Quality, Page 3.2-48). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.2, Air Quality, Page 3.2-52). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures: MM AIR-3 Selection of equipment during construction to minimize diesel particulate matter (DPM) emissions. The project shall implement the following: 1. Prior to the issuance of grading or construction permits, the applicant shall provide the Department of Conservation and Development, Community Development Division (CDD) with documentation to the satisfaction of CDD that all diesel-powered off-road equipment, larger than 25 horsepower, operating on the site for more than two days continuously, at a minimum, meet United States Environmental Protection Agency (EPA) emissions standards for Tier 4 Interim engines. Where Tier 4 equipment is not available, exceptions could be made for equipment meeting Tier 2 or Tier 3 standards that include California Air Resources Board (ARB)-certified Level 3 Diesel Particulate Filters or equivalent. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 60 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Equipment that is electrically powered or uses non-diesel fuels would also meet this requirement. 2. Minimize diesel generator use by providing line power to the site during early construction phases. 3. Avoid staging construction equipment near residences (i.e., within 200 feet of homes). Facts in Support of Findings As a residential project, the proposed project itself would be considered a sensitive receptor once operational. The project site is surrounded by existing residences to the south, east, and north of the project site. The closest off-site air pollution sensitive receptors in the vicinity of the project site include multi-family apartments north and south of the project site as well as single-family residences east of the project site across Oak Road. Structures to be demolished sometimes contain ACM. All ACM found on-site must be removed prior to demolition or renovation activity in accordance with BAAQMD Regulation 11, Rule 2, including specific requirements for surveying, notification, removal, and disposal of ACMs. Therefore, projects that comply with BAAQMD Regulation 11, Rule 2 would ensure that ACM would be removed and disposed of appropriately and safely. By complying with BAAQMD Regulation 11, Rule 2, thereby minimizing the release of airborne asbestos emissions during demolition. Furthermore, USGS map indicates that there are several locations within the County that are likely to contain naturally occurring asbestos; however, none of these sites are located within a 1-mile vicinity of the project site. Therefore, the proposed project would not expose sensitive receptors to naturally occurring asbestos during project construction (Draft EIR, Section 3.2, Air Quality, Page 3.2-49). Activities associated with earthmoving activities and construction would generate short-term emissions of fugitive dust resulting in increased dust fall and locally elevated levels of PM10 and PM2.5 downwind of construction activity. Construction dust has the potential for creating a nuisance at nearby properties. As addressed under Impact AIR-2, MM AIR-2 is included to ensure that the BAAQMD BMPs would be implemented to reduce fugitive dust emissions from construction activities (Draft EIR, Section 3.2, Air Quality, Page 3.2-49). During construction, the proposed project would result in the emissions of toxic air contaminants (TACs ) that could potentially impact nearby sensitive receptors. On-site diesel particulate matter (DPM) emissions would be generated by off-road construction equipment and the off-site DPM emissions would be generated by trips associated with the hauling of material, vendor trips, and worker vehicle traffic. Unmitigated incremental increase in cancer risk from construction was 16.3 per million at the maximally exposed individual (MEI). The maximum annual PM2.5 concentration from construction was 0.45 micrograms per cubic meter (μg/m3). Both exceed their respective BAAQMD single-source thresholds of greater than 10 in a million and greater than 0.3 μg/m3 for PM2.5 concentration. MM AIR-3 would reduce the generation of DPM during project construction to reduce health risk impacts to less than significant. With the incorporation of MMs AIR-2 and AIR-3, the incremental cancer risk and PM2.5 concentration would not exceed the appropriate BAAQMD’s single-source thresholds. Both Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 61 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx the unmitigated and mitigated non-cancer hazards from construction activities would be below the BAAQMD’s single-source significance threshold of 1.0 (Draft EIR, Section 3.2, Air Quality, Page 3.2- 50–51). The incorporation of MM AIR-3 would not reduce the annual PM2.5 concentration to below the BAAQMD’s community threshold of 0.8 μg/m3, ultimately resulting in a community annual PM2.5 concentration of 1.17 μg/m3. Nonetheless, as shown in Table 3.2-12, the proposed project’s contribution to that exceedance in community annual PM2.5 concentration constitutes an estimated 0.19 μg/m3. As such, without implementation of the proposed project, the area would otherwise experience an annual PM2.5 concentration of 0.98 μg/m3, which is currently above the BAAQMD’s threshold of 0.8 μg/m3. Therefore, because the proposed project would be implementing mitigation sufficient to reduce the proposed project’s health risk impacts to below the BAAQMD’s single-source thresholds and the annual PM2.5 concentration would exceed BAAQMD thresholds without implementation of the proposed project, the proposed project would not result in a significant impact or be cumulatively considerable (Draft EIR, Section 3.2, Air Quality, Page 3.2-51). The proposed project would not generate sufficient carbon monoxide (CO) emissions during project operation to substantiate the creation of a CO hotspot. Therefore, this impact would be less than significant with regard to exposing sensitive receptors to substantial concentrations of CO emissions. The County finds that MM AIR-3 is feasible, is adopted, and will further reduce impacts associated with Air Quality. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Air Quality would be less than significant with mitigation incorporated. Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would not result in significant cumulative air quality or health impacts (Draft EIR, Section 3.2, Air Quality, Page 3.2-54). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.2, Air Quality, Page 3.2-54). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental cumulative effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures Implement MM AIR-2 and MM AIR-3 above. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 62 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Facts in Support of Findings The determination of cumulative air quality impacts for construction and operational emissions is based on whether the proposed project would result in regional emissions that exceed BAAQMD regional thresholds of significance for construction and operations on a project level. Projects that generate emissions below the BAAQMD significance thresholds would be considered consistent with regional air quality planning efforts would not generate cumulatively significant emissions. As discussed in Impact AIR-2, with the incorporation of MM AIR-2, the proposed project would result in construction and operational emissions which are less than the respective BAAQMD significance thresholds and would therefore not have a cumulatively considerable contribution to a cumulative impact. The proposed project would therefore result in less than significant cumulative air quality impacts (Draft EIR, Section 3.2, Air Quality, Page 3.2-54). Regarding impacts to sensitive receptors, the DPM emissions from construction of the proposed project would result in less than significant health impacts after implementation of MM AIR-3 and would not combine with emissions from other cumulative projects to the extent that a significant cumulative impact would occur. In addition, the operational DPM emissions during operation of the proposed project would not result in significant health impacts and would constitute the greatest level of development. Given that the proposed project would be required to implement mitigation that is likely to result in decreased DPM emissions from what is disclosed in this analysis, the combined operation of the proposed project would not result in exposing nearby sensitive receptors to substantial amounts of pollutants. As discussed in Chapter 3, Environmental Impact Analysis, foreseeable future development projects in the area would not place new sensitive receptors near the proposed project that would be exposed to substantial amounts of pollutants. Therefore, the cumulative impact associated with construction and operation of the proposed project would be less than significant. Odor impacts that would be associated with the proposed project would principally be limited to the combustion of transportation fuels during construction and operation. The impact would be less than significant during project construction and operation would be intermittent and spatially dispersed. Therefore, cumulative odor impacts would be less than significant. 1.6.3 - Biological Resources Potential Effect Impact BIO-1 The proposed project could have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service. (Draft EIR, Section 3.3, Biological Resources, Page 3.3-19). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.3, Biological Resources, Page 3.3-21). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR.

A qualified wildlife Biologist shall conduct surveys for special-status bats during the appropriate time of day to maximize detectability to determine whether bat species are roosting near the work area no more than 5 days prior to beginning ground disturbance and/or construction. Survey methodology may include visual surveys of bats (e.g., observation of bats during foraging period), inspection for suitable habitat, bat sign (e.g., guano), or use of ultrasonic detectors (Anabat, etc.) 2. Visual surveys will include trees within 100 feet of project construction activities. Prior to building demolition, the applicants for development on any project parcel shall ensure that a qualified Biologist (i.e., one familiar with the identification of bats and signs of bats) survey buildings proposed for demolition for the presence of roosting bats or evidence of bats. If no roosting bats or evidence of bats are found in the structure, demolition may proceed. If the Biologist determines bats are present, the Biologist shall exclude the bats from suitable spaces by installing one-way exclusion devices. After the bats vacate the space, the Biologist shall close off the space to prevent recolonization. Building demolition shall only commence after the Biologist verifies 7 to 10 days later that the exclusion methods have successfully prevented bats from returning. To avoid impacts on non-volant (i.e., nonflying) bats, the Biologist shall only conduct bat exclusion and eviction from September 1 through March 31. Exclusion efforts shall be restricted during periods of sensitive activity. MM BIO-1b Migratory and Nesting Birds 1. If the project requires vegetation to be removed during the nesting season (February 1–August 31), pre-construction surveys shall be conducted 5 days prior to vegetation removal to determine whether or not active nests are present. 2. If an active nest is located during pre-construction surveys, a qualified Biologist shall determine an appropriately-sized avoidance buffer based on the species and anticipated disturbance level. Based on input from the Biologist, the project applicant will delineate the avoidance buffer using Environmentally Sensitive Area fencing, pin flags, and or yellow caution tape. The buffer zone will be maintained around the active nest site(s) until the young have fledged and are foraging independently. No construction activities shall be allowed within the avoidance buffer(s). 3. The qualified Biologist shall periodically monitor the active nest during construction activities to prevent any potential impacts that may result from the construction of the proposed project, until the young have fledged.

Suitable habitat requirements for special-status plant species include chaparral, riparian, alkaline, or serpentine soils; these features are absent from the project site. Therefore, no special-status plant species have the potential to occur within the project site and no special-status plant species would be impacted by project construction. Five special-status wildlife species (pallid bat, Townsend’s big-eared bat, big free-tailed bat, hoary bat, and white-tailed kite) as well as other birds protected under the MBTA and Fish and Game Code have potential to occur on the project site and, thus, have the potential to be impacted by project construction. Potential direct and indirect impacts could occur to roosting bats during project construction due to removal of potential roosting habitat, these impacts would be considered significant under CEQA. Implementation of MM BIO-1a, which requires the project applicant to conduct a pre-construction survey and to implement further avoidance and minimization measures (if bats are present), would reduce potential impacts to roosting bats Construction activities that occur during the avian nesting season (generally February 1 to August 31) could disturb nesting sites for bird species including special-status species such as the white- tailed kite as well as birds protected under the MBTA and the California Fish and Game Code. Implementation of MM BIO-1b, which requires the project applicant to conduct a pre-construction survey and to implement further avoidance and minimization measures (if necessary), would reduce potential impacts to nesting birds to a less than significant level under CEQA. The project site is surrounded by residential and commercial developments and is situated in an urban landscape with high amounts of traffic from local business operations, which create a baseline of ambient noise. The proposed project would increase traffic on local roadways and would introduce stationary noise sources through the operation of new a residential facility; however, noise emitted from the operation of the project would be within established standards and would not result in a significant increase in the ambient environment. Therefore, project implementation would not constitute a significant impact to wildlife species from operational noise including traffic noise (Draft EIR, Section 3.3, Biological Resources, Page 3.3-21). The County finds that MM BIO-1a and MM BIO-1b are feasible, are adopted, and will further reduce impacts associated with Biological Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Biological Resources would be less than significant with mitigation incorporated.

Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.3, Biological Resources, Page 3.3-23 – 24). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures: MM BIO-5a Prepare and Implement a Tree Replacement Plan A Tree Replacement Plan shall be submitted and approved by Department of Conservation and Development, Community Development Division (CDD) prior to the removal of trees, prior to issuance of a demolition or grading permit, whichever occurs first. The Tree Replacement Plan shall designate the approximate location, number, and sizes of trees to be planted. Trees shall be planted prior to requesting a final inspection of the building permit. MM BIO-5b Implement Tree Preservation Guidelines During Construction Tree protection guidelines shall be implemented during construction throughout the clearing, grading, and construction phases as outlined on pages 12 and 13 in the arborist report prepared by HortScience dated January 4, 2021. Facts in Support of Findings The Tree Report provides an inventory and preliminary evaluation of all trees over 6 inches in diameter within the project site. Trees that were surveyed were numbered, tagged, identified, measured, and evaluated. According to the Tree Report, a total of 74 trees would be removed as part of project implementation, one tree would be relocated, and six off-site trees would be preserved. Of the trees proposed for removal, 73 trees are considered protected due to their size, the remaining eight trees do not qualify as protected based on the Tree Protection and Preservation Ordinance. If not properly protected, the trees proposed for preservation could also be subject to injury or inadequate maintenance during construction, which represents a potentially significant impact. The response of individual trees would depend on the amount of excavation and grading, the care with which demolition is undertaken, and the construction methods. As the construction of the proposed project requires the removal of trees subject to the Contra Costa County Tree Protection and Preservation Ordinance, the applicant would be required to prepare and implement a tree replacement plan. In addition, remaining trees that are proposed for preservation on the project site would be preserved through the implementation of the tree preservations guidelines identified and outlined in the Tree Report and in the Contra Costa County Tree Protection and Preservation Ordinance.

The County finds that MM BIO-5a and MM BIO-5b are feasible, are adopted, and will further reduce impacts associated with Biological Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Biological Resources would be less than significant with mitigation incorporated. 1.6.4 - Cultural Resources and Tribal Cultural Resources Potential Effect Impact CUL-1 The proposed project could cause a substantial adverse change in the significance of a historical resource pursuant to Section 15064.5 (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-20). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-21). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures: MM CUL-1 Archaeological Spot-Monitoring and Halt of Construction Upon Encountering Historical or Archaeological Materials An Archaeologist who meets the Secretary of the Interior ’s Professional Qualification Standards for archaeology should inspect the site once grubbing and clearing are complete and prior to any grading or trenching into previously undisturbed soils. This will be followed by regular periodic or “spot-check” archaeological monitoring as determined by the Archaeologist. If the Archaeologist believes that a reduction in monitoring activities is prudent, then a letter report detailing the rationale for making such a reduction and summarizing the monitoring results shall be provided to the Department of Conservation and Development, Community Development Division (CDD) for concurrence.

The applicant for the proposed project shall include a standard inadvertent discovery clause in every construction contract to inform contractors of this requirement. Potentially significant cultural resources consist of but are not limited to stone, bone, glass, ceramics, fossils, wood or shell artifacts, or features including hearths, structural remains, or historic dumpsites. The Archaeologist shall make recommendations concerning appropriate measures that will be implemented to protect the resource, including but not limited to excavation and evaluation of the finds in accordance with Section 15064.5 of the CEQA Guidelines. Any previously undiscovered resources found during construction within the project site shall be recorded on appropriate California Department of Parks and Recreation (DPR) 523 forms and will be submitted to the Department of Conservation and Development, Community Development Division (CDD), the Northwest Information Center (NWIC), and the California Office of Historic Preservation (OHP), as required. Facts in Support of Findings Archival research identified a total of 15 previously recorded built environment resources within a 0.5-mile radius of the project site. Of these, 14 are historic-age buildings or structures located on the project site (single-family residences, industrial property, unidentified property) that have been previously found ineligible for listing in the National Register of Historic Places (NRHP) and/or California Register of Historical Resources (CRHR) and they do not qualify as historical resources. No previously recorded historical resources are present within or in close proximity to (within 50 feet of) the project site. The pedestrian survey identified the Palmer School, established in 1939. A review of aerial photographs indicated that some existing on-site buildings and structures date to 1965 or earlier, indicting they are 55 years old or more and above the 50 years age threshold for consideration for listing in the California Register. There are 14 historic-age buildings or structures (single-family residences, industrial property, unidentified property) located on the project site that have been previously found ineligible for listing in the NRHP and/or CRHR, and they do not qualify as historical resources. While unlikely, subsurface construction activities always have the potential to damage or destroy previously undiscovered historic resources such as wood, stone, foundations, and other structural remains; debris-filled wells or privies; and deposits of wood, glass, ceramic, and other refuse, if encountered. This would represent a potentially significant impact related to historic resources. Implementation of MM CUL-1, which requires an inspection and spot-monitoring by a qualified Archaeologist after clearing and grubbing are complete, but before any digging or trenching begin, would reduce potential impacts to historic resources that may be discovered during project construction, including off-site improvements (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-20).

No operational impacts would occur (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-21). The County finds that MM CUL-1 is feasible, is adopted, and will further reduce impacts associated with Cultural Resources and Tribal Cultural Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Cultural Resources and Tribal Cultural Resources would be less than significant with mitigation incorporated. Potential Effect Impact CUL-2 The proposed project could cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5 (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-21). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-22). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM CUL-1 above. Facts in Support of Findings Records search results indicate that 13 cultural resources have been mapped within a 0.5-mile radius of the project site. One of these is a prehistoric archaeological site and 12 are built environment resources. None of these resources are within or in close proximity to the project site. No archaeological resources have been recorded within the project site. However, the close proximity to the historical alignment of Walnut Creek, the relatively flat topography within the project site, and the occurrence of a nearby prehistoric archaeological site creates a potential for undiscovered prehistoric resources to occur within the project site. This represents a potentially significant impact related to archaeological resources. Implementation of MM CUL-1 requires inspection and spot-monitoring by a qualified Archaeologist after clearing and grubbing are complete but before any excavation or trenching begin, would reduce potential impacts to archaeological resources that may be discovered during project construction. Impacts related to a project’s potential to cause a substantial adverse change in the significance of an archaeological resource are limited to construction impacts.

The County finds that MM CUL-1 is feasible, is adopted, and will further reduce impacts associated with Cultural Resources and Tribal Cultural Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Cultural Resources and Tribal Cultural Resources would be less than significant with mitigation incorporated. Potential Effect Impact CUL-3 The proposed project could disturb human remains, including those interred outside of formal cemeteries (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-22). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-24). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures: MM CUL-3 Stop Construction Upon Encountering Human Remains In the event of the accidental discovery or recognition of any human remains, CEQA Guidelines Section 15064.5, Health and Safety Code Section 7050.5, and Public Resources Code Sections 5097.94 and Section 5097.98 shall be followed. If during the course of project construction, there is accidental discovery or recognition of any human remains, the following steps shall be taken: 1. There shall be no further excavation or disturbance within 100 feet of the remains until the County Coroner is contacted to determine whether the remains are Native American and if an investigation of the cause of death is required. If the Coroner determines the remains to be Native American, the Coroner shall contact the Native American Heritage Commission (NAHC) within 24 hours, and the NAHC shall identify the person or persons it believes to be the Most Likely Descendant (MLD) of the deceased Native American. The MLD may make recommendations to the landowner or the person responsible for the excavation work within 48 hours, for means of treating or disposing of, with appropriate dignity, the human remains and any associated grave goods as provided in Public Resources Code Section 5097.98. 2. Where the following conditions occur, the landowner or his or her authorized representative shall rebury the Native American human remains and associated grave goods with appropriate dignity either in accordance with the Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 70 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx recommendations of the MLD or on the project site in a location not subject to further subsurface disturbance: • The NAHC is unable to identify an MLD or the MLD failed to make a recommendation within 48 hours after being notified by the NAHC. • The descendant identified fails to make a recommendation. • The landowner or his authorized representative rejects the recommendation of the descendant, and mediation by the NAHC fails to provide measures acceptable to the landowner. Additionally, California Public Resources Code Section 15064.5 requires the following relative to Native American Remains: When an initial study identifies the existence of, or the probable likelihood of, Native American Remains within a project, a lead agency shall work with the appropriate Native Americans as identified by the NAHC as provided in Public Resources Code Section 5097.98. The applicant may develop a plan for treating or disposing of, with appropriate dignity, the human remains and any items associated with Native American Burials with the appropriate Native Americans as identified by the NAHC. Facts in Support of Findings No human remains or cemeteries are known to exist within or near the project site. However, there is always the possibility that subsurface construction activities associated with the proposed project, such as trenching and grading, could potentially damage or destroy previously undiscovered human remains. This represents a potentially significant impact related to human remains. However, in the unlikely event human remains are discovered, both within the project site and within the areas proposed for the off-site improvements, implementation of MM CUL-3 would require that work be halted, and the County Coroner be called to make a determination as to the nature of the remains and to confirm next steps regarding contacting the NAHC and appropriate tribal representatives. Impacts related to a project’s potential to disturb human remains are limited to construction impacts. No respective direct or indirect operational impacts related to human remains would occur (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-22–23). The County finds that MM CUL-3 is feasible, is adopted, and will further reduce impacts associated with Cultural Resources and Tribal Cultural Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Cultural Resources and Tribal Cultural Resources would be less than significant with mitigation incorporated.

Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-24). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM CUL-1 and MM CUL-3 above. Facts in Support of Findings A review of the CRHR, local registers of historic resources, a records search conducted at the NWIC, and an NAHC Sacred Lands File (SLF) search failed to identify any listed Tribal Cultural Resources (TCRs) that may be adversely affected by the proposed project. Moreover, no tribe requested consultation within the 30-day period established by AB 52. However, if a potential resource is identified, construction would be required to stop until appropriate identification and treatment measures are implemented (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-24). Impacts related to a project’s potential to cause a substantial adverse change in the significance of a State listed or eligible TCR are limited to construction impacts. No respective operational impacts would occur (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-24). The County finds that MM CUL-1 and MM CUL-3 are feasible, are adopted, and will further reduce impacts associated with Cultural Resources and Tribal Cultural Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Cultural Resources and Tribal Cultural Resources would be less than significant with mitigation incorporated.

(Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-25). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-25). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM CUL-1 and MM CUL-3 above. Facts in Support of Findings On August 13, 2020, ESA contacted the NAHC to determine whether any sacred sites are listed on its SLF for the project area. A response was received on August 18, 2020, and indicated that the SLF results failed to indicate the presence of Native American cultural resources in the immediate project area. The NAHC included a list of eight tribal representatives available for consultation. To ensure that all Native American knowledge and concerns over potential TCRs that may be affected by the proposed project are addressed, a letter containing project information and requesting any additional information was sent to each tribal representative on May 11, 2021. On March 9, 2021, the County notified the Wilton Rancheria pursuant to Public Resources Code Section 21080.3.1 that the proposed project may be within a geographic area in which the tribe may be traditionally and culturally affiliated. On March 11, 2021, the Wilton Rancheria responded that it has no concerns regarding the proposed project. However, if a potential resource is identified, construction would be required to stop until appropriate identification and treatment measures are implemented. Therefore, direct and indirect impacts related to TCRs would be less than significant with implementation MM CUL-1 and MM CUL-3. Impacts related to a project’s potential to cause a substantial adverse change in the significance of a State listed or eligible TCR are limited to construction impacts. No operational impacts would occur (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-25). The County finds that MM CUL-1 and MM CUL-3 are feasible, are adopted, and will further reduce impacts associated with Cultural Resources and Tribal Cultural Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Cultural Resources and Tribal Cultural Resources would be less than significant with mitigation incorporated.

(Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-25). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-25). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM CUL-1 and MM CUL-3 above. Facts in Support of Findings The geographic scope of the cumulative cultural resources analysis is the project vicinity. Cultural resource impacts tend to be localized, because the integrity of any given resource depends on what occurs only in the immediate vicinity around that resource, such as disruption of soils; therefore, in addition to the project site itself, the area near the project site would be the area most affected by project activities (generally within a 0.5-mile radius). Construction activities associated with development projects in the project vicinity may have the potential to encounter undiscovered cultural resources. These projects would be required to mitigate for impacts through compliance with applicable federal and State laws governing cultural resources. Although there is the possibility that previously undiscovered resources could be encountered by subsurface earthwork activities associated with the cumulative projects, the implementation of construction mitigation measures would ensure that undiscovered cultural resources are not adversely affected by cumulative project-related construction activities, which would prevent the destruction or degradation of potentially significant cultural resources (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-26). Therefore, cumulative impacts would be less than significant. Additionally, the proposed project’s contribution to these less than significant impacts would not be cumulatively considerable for the reasons details in Impact CUL-1 though CUL-5.

Refer to Division of Mines and Geology Special Publication 42. ii) Strong seismic ground shaking. iii) Seismic-related ground failure, including liquefaction. iv) Landslides. (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-16). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.6, Geology and Soils, Page 3.6- 12). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures: MM GEO-1a Conduct Design-level Geotechnical Exploration At least 60 days prior to recording the final Subdivision Map or requesting issuance of construction permits or installation of utility improvements, the applicant shall submit a design-level Geotechnical Exploration Report for the proposed project based on adequate subsurface exploration, laboratory testing, and engineering analysis. The scope of the Geotechnical Exploration Report shall address the following potential hazards: (i) grading, including removal of existing undocumented fill that is deemed to be unsuitable for use in engineered fills, preparation to receive fill, compaction standards for fill, etc., (ii) consolidation settlement, (iii) analysis of liquefaction potential, including estimating total settlement and differential settlement, and surface manifestation of liquefaction, (iv) foundation design, (v) measures to protect improvements from the relatively shallow water table, (vi) laboratory testing to evaluate the expansive and corrosion potential soils and measures designed to protect improvements that are in contact with the ground from these hazards, including the building foundation, parking garage slabs, flatwork, pavement, and utilities, (vii) exploration, testing, and engineering analysis aimed at providing recommendations pertaining to foundation design, including foundation retaining walls, and pavement design, (viii) evaluation of the drainage design, including the proposed bioretention facilities and their effect on planned improvements, (ix) address temporary shoring and support of excavations, (x) provide updated California Building Standards Code (CBC) seismic parameters, and (xi) outline the recommended geotechnical monitoring, commencing with clearing Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 75 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx and demolition, extending through final grading, installation of drainage improvements, and including the monitoring of foundation-related work. MM GEO-1b Conduct Geotechnical Observation and Testing Services During Construction The design-level geotechnical report required by Mitigation Measure GEO-1a routinely includes recommended geotechnical observation and testing services during construction. These services are essential to the success of the proposed project. They allow the Geotechnical Engineer to (i) ensure geotechnical recommendations for the proposed project are properly interpreted and implemented by contractors, (ii) allow the Geotechnical Engineer to view exposed conditions during construction to ensure that field conditions match those that were the basis of the design recommendations in the approved report, and (iii) provide the opportunity for field modifications of geotechnical recommendations (with Department of Conservation and Development, Community Development Division approval), based on exposed conditions. The monitoring shall commence during clearing, and extend through grading, placement of engineered fill, installation of recommended drainage facilities, and foundation-related work. A hold shall be placed on the "final" grading inspection, pending submittal of a report from the project Geotechnical Engineer that documents their observation and testing services to that stage of construction, including monitoring and testing of backfilling required for utility and drainage facilities. Similarly, a hold shall be placed on the final inspection for each residential building, pending submittal of a letter report from the Geotechnical Engineer documenting the monitoring services associated with implementation of final grading, drainage, and foundation-related work. This can be one letter that addresses all residential buildings, or separate letters for each building. The geotechnical monitoring shall include documentation of conformance of retaining wall, pier hole drilling/ foundation preparation work, and installation of drainage improvements. MM GEO-1c Prepare Final Construction Report The Geotechnical Engineer shall prepare a final report that documents the field observations and testing services provided during construction as well as provide a professional opinion on the compliance of construction with the recommendations in the Preliminary Geotechnical Exploration. The final report can be segmented into an as-graded report that is issued at the end of rough grading, but prior to the installation of the foundations, and a second letter commenting on the inspections made during installation of foundations/parking lot/drainage facilities. The Department of Conservation and Development, Community Development Division (CDD) will place a hold on the final inspection, to ensure that the Geotechnical Engineer’s grading-foundation inspection letter report is provided prior to requesting the final building inspection for each building. This requirement may be Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 76 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx satisfied by issuance of one letter for all residential buildings, or separate letters for each residential building. Facts in Support of Findings Impacts related to risks associated with seismic-related hazards are limited to operational impacts. Ground Rupture Based on the Geologic Peer Review (Appendix E), the potential for ground rupture is low. There are no known active faults directly crossing the project site and the project site is not located within a designated Alquist-Priolo Earthquake Fault Zone. The closest fault to the project site is the Concord fault, approximately 3 miles from the project site. As such, it is unlikely for ground rupture to occur at the site. Strong Seismic Ground Shaking Potential impacts associated with strong seismic shaking at the project site, including the areas proposed for off-site improvements, include the potential to damage structures or improvements or result in the injury or loss of human life, which could represent a potentially significant impact. The risk of damage from ground shaking is controlled by using sound engineering judgment and compliance with the latest provisions of the CBC, as a minimum. MM GEO-1a would ensure that the proposed project would incorporate all applicable seismic safety building standards contained in the CBC including seismic design provisions, which would reduce the risk of loss, injury, or death. MM GEO-1b would require geotechnical observation and testing services be conducted during construction as needed, and MM GEO-1c would require the Project Engineer to prepare a final report that documents the field observations and testing services provided during construction as well as provide a professional opinion on the compliance of construction with the recommendations in the Preliminary Geotechnical Investigation. MM GEO-1a, MM GEO-1b, and MM GEO-1c are also applicable to the off-site improvements. Furthermore, the proposed project would be required to comply with Chapter 74-2 of the Ordinance Code, which requires all construction to conform to the 2019 CBC. Seismic-related Ground Failure The potential for liquefaction at the project site is moderate to low. The areas proposed for off-site improvements are likely to contain similar soil conditions and susceptibility to liquefaction. The Preliminary Geotechnical Investigation stated that an investigation would be needed to determine whether liquefiable sands are present and to provide stabilization measures where liquefiable sands are confirmed. MM GEO-1a would require the Project Engineer to prepare a design-level Geotechnical Investigation and to incorporate all recommendation from that report into grading and construction drawings to address the presence of liquefiable sands. Landslides The project site is relatively flat with no slopes or varied topography that could be susceptible to slope failure, landslides, or soil creep. Due to the relatively flat nature of the project site, the potential for landslides is low to negligible.

Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Geology and Soils would be less than significant with mitigation incorporated. Potential Effect Impact GEO-2 The proposed project could result in substantial soil erosion or the loss of topsoil. (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-16). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.6, Geology and Soils, Page 3.6- 16). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures: MM GEO-2 Conduct Grading, Excavation, and Filling Only During the Dry Season All grading, excavation and filling shall be conducted during the dry season (April 15 through October 15) only, and all areas of exposed soils shall be revegetated to minimize erosion and subsequent sedimentation. After October 15, only erosion control work shall be allowed by the grading permit. Any modification to the above schedule shall be subject to review by the Grading Inspection Division, and the review/approval of the Department of Conservation and Development, Community Development Division (CDD). Facts in Support of Findings Impacts related to soil erosion or loss of topsoil are limited to construction impacts. The proposed project would be required to obtain a Construction General Permit from the State Water Board consistent with the Contra Costa County’s General Permit (No. CAS612008) and to comply with its conditions and requirements, which are designed to minimize potential erosion issues. Consistent with Section 1014-4.002 and .004, compliance with the County’s NPDES Permit would ensure that a stormwater control plan is prepared and BMPs are implemented that would prevent sediments and other pollutants from entering the stormwater system. To further reinforce protections related to erosion, MM GEO-2 would require grading, excavation, and filling to occur during the dry season. Thus, with adherence to existing regulatory requirements, as well as limiting grading, excavation, and filling to the dry season, impacts from project construction on the project site, including the off-site improvements, would not result in substantial soil erosion or loss of topsoil (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-16). The County finds that MM GEO-2 is feasible, is adopted, and will further reduce impacts associated with Geology and Soils.

Therefore, impacts associated with Geology and Soils would be less than significant with mitigation incorporated. Potential Effect Impact GEO-3 The proposed project could be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the proposed project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-17). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.6, Geology and Soils, Page 3.6- 18). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM GEO-1a, MM GEO-1b, and MM GEO-1c above. Facts in Support of Findings Impacts related to risks associated with location on an unstable geologic unit or soil are limited to operational impacts. The potential for liquefaction at the project site will be investigated further as part of the design-level Geotechnical Investigation, with recommendations incorporated into grading and construction drawings to address the potential presence of liquefiable sands. In addition, the potential for lateral spreading to occur as a result of the occurrence of liquefaction below the project site is low. The project site, including the areas proposed for off-site improvements, do not contain steep slopes, exposed hillsides, or vertical cuts. Due to the gently sloping nature of the project site, including the areas proposed for off-site improvements, the potential for landslides is low. According to the Soil Survey of Contra Costa County, the soil series that occurs on the project site is indicated to be very highly corrosive. Corrosive soil can damage buried metal and result in sulfate attack on foundation concrete. This is a potentially significant impact. In order to reduce or avoid potential impacts related to unstable soils, corrosive soils, or other ground failure, MM GEO-1a would be required to ensure that the proposed project incorporates all applicable seismic safety building standards contained in the CBC as well as all recommendations from a design-level geotechnical exploration. MM GEO-1b would require geotechnical observation and testing services be conducted during construction as needed, and MM GEO-1c would require the Project Engineer to prepare a final report that documents the field observations and testing services provided during construction as well as provide a professional opinion on the compliance of construction with the recommendations in the design-level geotechnical exploration. MM GEO-1a, MM GEO-1b, and MM GEO-1c are also applicable to the off-site improvements (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-17–18). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 79 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx The County finds that MM GEO-1a, MM GEO-1b, and MM GEO-1c are feasible, are adopted, and will further reduce impacts associated with Geology and Soils. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Geology and Soils would be less than significant with mitigation incorporated. Potential Effect Impact GEO-4 The proposed project could be located on expansive soil, as defined in Table 18-1- B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property. (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-18). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.6, Geology and Soils, Page 3.6- 18). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM GEO-1a, MM GEO-1b, and MM GEO-1c above. Facts in Support of Findings Impacts related to risks associated with location on expansive soil are limited to operational impacts. The Preliminary Geotechnical Investigation suggests clayey soil is present at the site, which may exhibit expansive potential. The presence of potentially expansive soil shall be further evaluated during the design-level geotechnical exploration. The soil present on-site, Clear Lake clay, is highly expansive. Expansive soils expand when water is added and shrink when they dry out. This continuous change in soils volume could cause homes and other structures to move unevenly and crack. With implementation of MM GEO-1a, MM GEO-1b, and MM GEO-1c, the proposed project, including the off-site improvements, would not create a substantial risk to life or property from being located on expansive soils (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-18). The County finds that MM GEO-1a, MM GEO-1b, and MM GEO-1c are feasible, are adopted, and will further reduce impacts associated with Geology and Soils. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Geology and Soils would be less than significant with mitigation incorporated. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 80 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Potential Effect Impact GEO-6 The proposed project would not directly or indirectly destroy a unique paleontological resource or site or unique geologic feature (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-19). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-19). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures MM GEO-6 Stop Construction Upon Encountering Paleontological Materials In the event that fossils or fossil-bearing deposits are discovered during construction activities, excavations within a 50-foot radius of the find shall be temporarily halted or diverted. The project contractor shall notify a qualified Paleontologist to examine the discovery. The Paleontologist shall document the discovery as needed (in accordance with Society of Vertebrate Paleontology [SVP] standards), evaluate the potential resource, and assess the significance of the find under the criteria set forth in CEQA Guidelines Section 15064.5. The Paleontologist shall notify the appropriate agencies to determine procedures that would be followed before construction activities are allowed to resume at the location of the find. If the applicant determines that avoidance is not feasible, the Paleontologist shall prepare an excavation plan for mitigating the effect of construction activities on the discovery. The excavation plan shall be submitted to the Lead Agency for review and approval prior to implementation, and the applicant shall adhere to the recommendations in the excavation plan. Facts in Support of Findings No known paleontological resources are located within the project site boundaries. The surface area of the project sites consists of solely Holocene alluvium, which is too young to contain significant vertebrate fossils. The 0.5-mile search area around the project site boundary also only contains Holocene alluvium. The nearest area with potential to contain significant fossils are resources is in the outcrop belt of Miocene Monterey Formation shale and sandstone and the Paleocene Martinez Formation. These bedrock exposures occur outside of the search area. The absence of Pleistocene or older deposits in the search area suggests that any potential paleontological resources underlying the project site would be at depths below all the earth-disturbing construction activities at the project site. In addition, there are no unique geological features located on the project site. Nonetheless, development activities have the potential to encounter undiscovered paleontological resources. Accordingly, MM GEO-6 requires the implementation of standard inadvertent discovery measures in the event paleontological resources are encountered during construction. The implementation of this mitigation measure would ensure that construction shall stop in the vicinity of any potential resource until the significance of the resource is confirmed and would ensure that Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 81 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx significant resources will be avoided or excavated and preserved (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-19). The County finds that MM GEO-6 is feasible, is adopted, and will further reduce impacts associated with Geology and Soils. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Geology and Soils would be less than significant with mitigation incorporated. 1.6.6 - Hazards and Hazardous Materials Potential Effect Impact HAZ-1 The proposed project could create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-19). Findings Less than significant impact with mitigation incorporated. (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-19.) Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM HAZ-1a Conduct Asbestos and Lead Surveys Prior to Demolition Prior to the issuance of demolition permits for the existing structures, the applicant shall retain a licensed professional to conduct asbestos and lead paint surveys. These surveys shall be conducted prior to the disturbance or removal of any suspect asbestos-containing materials (ACM) and lead-based paint (LBP), and these materials shall be characterized for asbestos and lead by a reliable method. All activities involving ACM and LBP shall be conducted in accordance with governmental regulations, and all removal shall be conducted by properly licensed abatement contractors. MM HAZ-1b Proper Disposal of Hazardous Materials Such as Cleaning Supplies and Insecticides Prior to the issuance of a grading permit, the applicant shall remove and dispose of all materials observed during the site reconnaissance for the Phase I Environmental Site Assessment (Phase I ESA) in accordance with applicable local, State, and federal regulations. The materials include, but are not limited to containers of cleaning supplies and insecticides. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 82 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx MM HAZ-1c Closure of On-site Irrigation Wells Prior to the issuance of a grading permit, the three on-site irrigation wells shall be properly closed under permit in accordance with applicable local, State, and federal regulations. MM HAZ-1d Soil Aeration The applicant shall complete the soil aeration and soil vapor testing during demolition and rough grading operations. Once the soil aeration is completed which consists of spreading excavated soil on the ground in an approximately 18-inch-thick layer, mixing of the soil (tilling) shall be performed regularly to maintain aerobic conditions (presence of oxygen). The soil shall be thoroughly tilled using equipment such as a Terex RS600 Reclaimer/Stabilizer. An Environmental Health Licensed Professional shall spot-check to ensure that the process is implemented. A total of six tilling passes shall be performed through the proposed excavation area (approximately 30 feet long by 20 feet wide and 6 feet deep with a total volume of 135 cubic yards). During the tilling operation, air quality monitoring shall be performed with a photo ionization detector (PID) 3 inches above the soils and also in the breathing zone. Dust control measures shall be implemented during the aeration process (as spelled out in MM AIR-2), and dust monitoring shall be performed in the perimeter of the project site. Soil vapor sampling shall be performed at the end of aeration/tilling operations prior to backfill. If the soil vapor sampling finds no benzene Environmental Screening Level (ESL) exceedances, then the applicant shall have the Phase I Environmental Site Assessment and Phase II Environmental Investigation Report prepared by Roux Associates, Inc. (Roux) in August 2021, updated memorializing the implementation of the mitigation and confirming that no Recognized Environmental Conditions (REC) exist on the site and provide a copy to the Department of Conservation and Development, Community Development Division demonstrating that benzene levels no longer exceed the ESL. If soil vapor exceedances are identified after soil excavation and aeration, then a Soil Management Plan (SMP) shall be prepared and forwarded to an appropriate environmental oversight agency for disposition. A copy of the SMP will also be provided to the Department of Conservation and Development, Community Development Division. All construction work shall cease in the area of the underground storage tank (UST) as shown in the Roux report, including the aeration area, until the disposition of the SMP is determined by the environmental oversight agency. Once the issue has been addressed to the satisfaction of the environmental oversight agency, evidence shall be provided to the satisfaction of the Department of Conservation and Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 83 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Development, Community Development Division and construction activities may resume on the former UST area. Facts in Support of Findings During construction, both within the project site and within the areas proposed for the off-site improvements, the proposed project would be expected to involve the transport, use, and disposal of hazardous materials, such as diesel fuels, aerosols, and paints. The proposed project would be subject to the Hazardous Materials Transportation Act, California Public Resources Code, and other State and local regulations that would reduce and limit the associated risks. Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations, including the EPA, RCRA, Caltrans, and HMP. During project site preparation, all existing structures, pavement, and landscaping would be demolished. Given the age of the existing structures on the project site, it is conceivable that ACM and LBP may exist within these structures, and their removal could potentially create a significant hazard to construction workers. This represents a potentially significant impact. However, implementation of MM HAZ-1a requires the applicant to conduct asbestos and lead paint surveys prior to demolition activities and to safely remove and dispose of any such materials in accordance with State standards (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-19). No hazardous materials other than small containers of conventional cleaning supplies and insecticides were observed at the project site. HAZ-1b would require proper removal and disposal of these existing materials. Three irrigation wells were observed on-site: One at a depth of approximately 60 feet below ground surface (bgs) and accompanied by a filter and a pressure tank, and two of unknown depths. One of these wells was observed to be uncovered. Should these groundwater irrigation wells be encountered during ground-disturbing activities, construction workers could potentially be exposed to a significant hazard. This represents a potentially significant impact. MM HAZ-1c requires proper closure of the three irrigation wells in accordance with local, State, and federal regulations. A 50-gallon underground storage tank (UST) was removed from the site approximately 25 years ago without regulatory oversight. Although no indication of a release has been reported and the tank was relatively small, it is possible that releases from the gasoline UST could have historically occurred, which is considered a Recognized Environmental Condition (REC). Benzene concentrations in soil vapor from all five soil vapor probes in the vicinity of the former UST exceeded the RWQCB Residential ESL. While concentrations were relatively low, to ensure no benzene ESL exceedances, HAZ-1d would require soil aeration to reduce impacts to below a level of significance. During project operations, hazardous materials may be handled on the project site. Because of the nature of the project, hazardous materials would likely be limited to small quantities of fertilizers, herbicides, pesticides, solvents, cleaning agents, and similar materials used for daily residential operations and maintenance activities. These types of materials are common for residential developments and represent a low risk to people and the environment when used as intended.

The County finds that the project, as designed and with implementation of existing regulations and mitigation, would not cause substantial adverse effects on human beings. The County finds that MM HAZ-1a, MM HAZ-1b, and MM HAZ-1c, and MM HAZ-1d are feasible, are adopted, and will further reduce impacts associated with Hazards and Hazardous Materials. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Hazards and Hazardous Materials would be less than significant with mitigation incorporated. Potential Effect Impact HAZ-4 The proposed project could be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment. (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8- 24). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-24). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures Implement MM HAZ-1d above. Facts in Support of Findings Impacts related to locating a project on a hazardous materials site per Government Code Section 65962.5 are limited to operational impacts. Based on a regulatory records review as part of the Phase I ESA, benzene concentrations in soil vapor from five soil vapor probes in the vicinity of the former 50-gallon UST exceeded the RWQCB Residential ESL. While concentrations were relatively low, to ensure no benzene ESL exceedances, HAZ-1d would require soil aeration to reduce impacts to below a level of significance (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-24). The County finds that MM HAZ-1d is feasible, is adopted, and will further reduce impacts associated with Hazards and Hazardous Materials. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Hazards and Hazardous Materials would be less than significant with mitigation incorporated.

(Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-19). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-21). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM HYD-3 Prepare Final Drainage Plan Prior to Grading • In accordance with Division 914 of the County Ordinance Code, the project shall collect and convey all stormwater entering and/or originating on this property, without diversion and within an adequate storm drainage facility, to a natural watercourse having definable bed and banks, or to an existing adequate public storm drainage system that conveys the stormwater to a natural watercourse. Any proposed diversions of the watershed shall be subject to hearing body approval. Prior to issuance of a grading permit, the applicant shall obtain a Flood Control Permit from the applicant and Permit Center, submit improvement plans for proposed drainage improvements, and a drainage report with hydrology and hydraulic calculations to the Engineering Services Division of the Public Works Department for review and approval that demonstrates the adequacy of the in- tract drainage system and the downstream drainage system. The applicant shall verify the adequacy at any downstream drainage facility accepting stormwater from this project prior to discharging runoff. If the downstream system(s) is not adequate to handle the Existing Plus Project condition for the required design storm, improvements shall be constructed to make the system adequate. The applicant shall obtain access rights to make any necessary improvements to off- site facilities.

Improvement Plans shall be reviewed to verify consistency with the Final Stormwater Control Plan and compliance with the Contra Costa Stormwater C.3 Guidebook of the County’s NPDES Permit and the County’s Stormwater Management and Discharge Control Ordinance (Division 1014) and be designed to discourage prolonged standing/ponding of water on-site. Facts in Support of Findings Construction-related Erosion and Siltation Construction activity such as grading and excavation could result in an alteration to the existing drainage pattern, potentially resulting in erosion or siltation that could result in polluted runoff exiting the site. MM HYD-3 would ensure the proposed project complies with regulations of the NPDES permit consistent with Division 1014 of the Ordinance Code. Additionally, as part of compliance with Division 1014 of the Ordinance Code, the proposed project would also be required to prepare and implement a SWPPP to ensure that erosion, siltation, and flooding are prevented or minimized to the maximum extent feasible during construction. The SWPPP includes both structural (physical devices or measures) and operational (timing of construction) BMPs that would prevent or reduce the discharge of pollutants directly or indirectly into waterbodies. As part of the SWPPP, erosion and control measures would be implemented throughout the duration of construction, including rock barrier bags placed around the catch basin until the site is paved, temporary sediment basins, placement of coarse aggregate gravel at each driveway entrance to the site such that mud or sediments would not be tracked off-site by construction vehicles, and maintenance of the site to minimize sediment entering any storm drain system in stormwater runoff. Operation-related Erosion and Siltation Development of the project site would increase impervious surfaces by 36,420 square feet compared to existing conditions and could result in increased amounts of stormwater runoff that could carry pollutants off-site. MM HYD-3 would ensure the proposed project collects and conveys stormwater entering or originating from the project site consistent with Division 1014 of the Ordinance Code. MM HYD-3 would also require the project applicant to prepare and submit a Final Storm Water Control Plan and Storm Water Control O&M Plan for review and approval by the County Public Works Department and would ensure a permanent funding source for the operation and maintenance of project stormwater facilities, which would result in a reduction of stormwaters flowing from the site compared to the current condition. In addition, the proposed project would Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 87 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx comply with the County’s NPDES program and the CCCWP as well as all relevant provisions of the Ordinance Code related to stormwater pollution, and would also be required to pay drainage fees in accordance with Flood Control Ordinance number 89-24. Construction-related Surface Runoff MM HYD-3 would ensure compliance with regulations of the NPDES permit. Additionally, the proposed project would be required to prepare and implement a SWPPP to ensure that erosion, siltation, and flooding are prevented or minimized to the maximum extent feasible during construction. The SWPPP would include both structural and operational BMPs that would prevent or reduce the amount of stormwater runoff that could be deposited directly or indirectly into waterbodies. As part of the SWPPP, erosion and control measures would be implemented throughout the duration of construction that would also limit the volume of stormwater that would be discharged. These measures would include rock barrier bags placed around the catch basin until the site is paved and temporary sediment basins that would retain stormwater to prevent significant peak flows. Operation-related Surface Runoff Under existing conditions, stormwater runoff generally sheet flows across the site or is captured by small drainage inlets on-site that connect by underground storm drain pipes and discharge into existing storm drain facilities in Jones Road and Oak Road. The proposed project would increase impervious surfaces by 36,420 square feet compared to existing conditions, which could increase surface runoff and potentially cause flooding on- or off-site. The applicant would be required to comply with Division 914 of the Ordinance Code, which addresses drainage, including provisions requiring appropriate collection and conveyance. The applicant would also be required to implement MM HYD-3, which would ensure that the site discharges to facilities with adequate capacity and that downstream facilities, if necessary, be made adequate to accommodate runoff from and through the site. As part of the proposed on-site drainage improvements, runoff from impervious areas on the project site would be routed to 34 bioretention areas for treatment before being discharged into underground storm drains; these improvements would ensure that post-construction surface runoff would be less than existing conditions (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-19). Construction-related Exceedance of Storm Drain Capacity During construction, the proposed project could increase stormwater runoff generation, which could potentially lead to flooding on or off-site. However, the proposed project would be required to implement a SWPPP as part of its Construction General Permit to ensure that stormwater generation and pollutants are prevented or minimized to the maximum extent feasible during construction through the implementation of standard BMPs. Operation-related Exceedance of Storm Drain Capacity The proposed project would not increase impervious surfaces compared to existing conditions and, therefore, is not likely generate increased amounts of runoff. As described in the Stormwater Control Plan, the proposed project would incorporate LID techniques to allow for stormwater infiltration and treatment in 34 bioretention areas before being discharged to the storm drain system. The proposed Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 88 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx project would use 100 percent LID, meaning 100 percent of project runoff would be contained and treated on-site before being discharged. This would be accomplished by optimizing site layout and using drainage swales, curb openings, and bubble ups to convey the runoff to the treatment areas in paseos, landscape pockets between walkways/buildings, and the center open space area on the project site. Furthermore, compliance with the CCCWP and the Ordinance Code would ensure that project operation would not create runoff that exceeds the capacity of existing or planned stormwater drainage systems or provide sources of stormwater or polluted runoff. Thus, operation of the project would not create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff. Construction-related Impacts to Flood Flows Impacts related to impedance of flood flows would only occur during the operational phase of the project. As such, no construction impedance of flood flow impacts would occur. Operation-related Impacts to Flood Flows The project site is designated Zone X—area of minimal flood hazard. The project site is not susceptible to inundation from flood hazards, tsunamis, or seiches. As a result, the proposed project is not anticipated to have any effect in terms of impeding or redirecting flood flows. The County finds that MM HYD-3 is feasible, is adopted, and will further reduce impacts associated with Hydrology and Water Quality. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Hydrology and Water Quality would be less than significant with mitigation incorporated. 1.6.8 - Noise Potential Effect Impact NOI-1 The proposed project could cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect (Draft EIR, Section 3.11, Noise, Page 3.11-15). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.11, Noise, Page 3.11- 16). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM NOI-1 Implement Traffic Noise-reduction Measures To reduce potential traffic noise impacts, the following multi-part mitigation measure shall be implemented for the proposed project: Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 89 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx • The project applicant shall ensure inclusion of ventilation systems that would permit windows to remain closed for prolonged periods. The systems must not compromise sound insulation of the exterior wall assemblies. • Prior to issuance of building permits, the project applicant shall provide design plans which show that window and exterior door assemblies of units located within 175-feet of the centerline of Jones Road will have ratings of Sound Transmission Class (STC) 39 to reduce project traffic noise levels to meet the interior noise level standards. Alternatively, the project applicant shall provide a design-level noise study that demonstrates the specific window and door assembly sound ratings to achieve the required interior noise threshold for each of these impacted residential units. • Prior to issuance of building permits, the project applicant shall provide design plans which show that window and exterior door assemblies of units located within 100-feet of the centerline of Oak Road will have ratings of STC 34 to reduce project traffic noise levels to meet the interior noise level standards. Alternatively, the project applicant shall provide a design-level noise study that demonstrates the specific window and door assembly sound ratings to achieve the required interior noise threshold for each of these impacted residential units. Facts in Support of Findings Estimated future noise levels at future façades range from 60 A-weighted decibels (dBA) Day-Night Level (DNL) at interior shielded portions of the site to approximately 74 dBA DNL at elevated locations nearest the BART tracks and I-680. This falls into the County’s normally acceptable to normally unacceptable land use compatibility categories for multi-family residences. According to the noise study, window and exterior door assemblies of units located within 175-feet of the centerline of Jones Road will need to have Sound Transmission Class (STC) ratings of STC 39 to reduce project traffic noise levels to meet the interior noise level standards; while units located within 100 feet of the centerline of Oak Road will need to have ratings of STC 34 to reduce project traffic noise levels to meet the interior noise level standards. Implementation of the project could expose the proposed residential land uses to noise levels that would conflict with the County’s established noise land use compatibility standards adopted for the purpose of avoiding or mitigating an environmental effect. MM NOI-1 would reduce this impact to below a level of significance by requiring the project to include a code compliant mechanical ventilation system that would permit windows to remain closed for prolonged periods, as well as upgraded window and door assemblies to ensure compliance with the interior noise standard of 45 dBA DNL. This measure would ensure that potentially impacted interior residential units would meet the interior noise level requirement of 45 dBA DNL. Prior to the issuance of building permits, the project applicant would be required to demonstrate that windows and doors have been incorporated that reduce project traffic noise levels to meet the interior noise level standards. Alternatively, the project applicant would be required to provide a design-level noise study that demonstrates the specific window and door assembly sound ratings to achieve the required interior Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 90 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx noise threshold for each of these impacted residential units. Accordingly, with implementation of MM NOI-1, this impact would be reduced to less than significant (Draft EIR, Section 3.11, Noise, Page 3.11-16). The County finds that MM NOI-1 is feasible, is adopted, and will further reduce impacts associated with noise. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with noise would be less than significant with mitigation incorporated. Potential Effect Impact NOI-2 The proposed project could generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies (Draft EIR, Section 3.11, Noise, Page 3.11-17). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.11, Noise, Page 3.11- 20). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM NOI-2 Implement Noise-reduction Measures During Construction To reduce potential construction noise impacts, the following multi-part mitigation measure shall be implemented for the proposed project: • The construction contractor shall ensure that all equipment driven by internal combustion engines shall be equipped with mufflers, which are in good condition and appropriate for the equipment. • The construction contractor shall ensure that unnecessary idling of internal combustion engines (i.e., idling in excess of 5 minutes) is prohibited. • The construction contractor shall utilize “quiet” models of air compressors and other stationary noise sources where technology exists. • At all times during project grading and construction, the construction contractor shall ensure that stationary noise-generating equipment shall be located as far as practicable from sensitive receptors and placed so that emitted noise is directed away from adjacent residences. • The construction contractor shall ensure that the construction staging areas shall be located to create the greatest feasible distance between the staging area and noise-sensitive receptors nearest the project site.

The disturbance coordinator will determine the cause of the noise complaint (e.g., bad muffler, etc.) and will require that reasonable measures be implemented to correct the problem. • The construction contractor shall ensure that noise-generating construction activities (including construction-related traffic, excluding interior work within the building once the building envelope is complete) at the project site and in areas adjacent to the project site are limited to the hours of 8:00 a.m. to 5:00 p.m., Monday through Friday, unless otherwise approved by the Department of Conservation and Development, Community Development Division (CDD), with no construction allowed on weekends, federal, and State holidays. Facts in Support of Findings Construction Noise impacts from construction activities associated with the project would be a function of the noise generated by construction traffic, construction equipment, equipment location, sensitivity of nearby land uses, and the timing and duration of the construction activities. The transport of workers and construction equipment and materials to the project site would incrementally increase noise levels on access roads leading to the site. Because project construction workers and construction equipment would use existing routes, noise from passing trucks would be similar to existing vehicle-generated noise on these local roadways. In addition, these trips would not result in a doubling of daily traffic volumes on any of the local roadways in the project vicinity and would thus not result in a perceptible change in existing traffic noise levels. For this reason, intermittent noise from construction trips would be minor when averaged over a longer time period and would not be expected to result in a perceptible increase in hourly or average daily traffic noise levels in the project vicinity. Noise levels vary as construction progresses. Despite the variety in the types and sizes of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction noise ranges to be categorized by work phase. The site preparation phase, which includes excavation and grading activities, tends to generate the highest noise levels. Construction of the proposed project is expected to require the use of scrapers, bulldozers, water trucks, haul trucks, and pickup trucks. Assuming that each piece of construction equipment operates at some distance from the other equipment, a reasonable worst-case combined noise level during this phase of construction would be 90 dBA maximum sound level (Lmax) at a distance of 50 feet from the acoustic center of a construction area. This would result in a reasonable worst-case hourly average of 86 dBA equivalent sound level (Leq). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 92 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx The nearest off-site noise-sensitive receptor to the project site is the multi-family residence located southeast of the project building, which would be located approximately 70 feet from the acoustic center of construction activity where multiple pieces of heavy machinery would operate. At this distance, construction noise levels at the exterior façade of this nearest residential home would be expected to range up to approximately 87 dBA Lmax, with a worst-case hourly average of approximately 83 dBA Leq, intermittently, when multiple pieces of heavy construction equipment operate simultaneously at the nearest construction footprint. These noise levels would be intermittent and would be reduce as equipment moves over the project site further from adjacent sensitive receptors. Therefore, restricting construction activities to non-weekend, non-holiday daytime hours of 7:00 a.m. to 6:00 p.m. would ensure that construction noise would not result in a substantial exceedance of the construction noise standards established by General Plan Policy 11-8 and the Walnut Creek Municipal Code. Additionally, MM NOI-2 requires adherence to the County’s permissible construction hours and also requires implementation of best management noise reduction techniques and practices that would ensure that construction noise levels would not result in a substantial temporary increase in ambient noise levels that would result in annoyance or sleep disturbance of nearby sensitive receptors (Draft EIR, Section 3.11, Noise, Page 3.11-18). Operation The proposed project would result in an increase in traffic on local roadway segments in the project vicinity. In addition, implementation of the project would introduce new stationary noise sources to the ambient noise environment in the project vicinity, including new mechanical ventilation equipment. The intersection volume data indicates that peak-hour traffic volumes will increase by 3 percent or less, which corresponds with less than a 1 dB increase in the traffic noise levels DNL. Therefore, project-related traffic noise level would result in less than significant increases in traffic noise levels along modeled roadway segments in the project vicinity. For project-related stationary noise sources, Contra Costa County established a maximum exterior noise performance threshold for receiving residential land uses of 65 dBA DNL. Contra Costa County also established a maximum interior noise threshold of 45 dBA DNL; however, if ambient noise levels exceed 65 dBA DNL due to train noise, the maximum interior noise threshold would be 50 dBA DNL in bedrooms and 55 dBA DNL in other habitable rooms. Implementation of the project would introduce new stationary noise sources to the ambient noise environment in the project vicinity, including new mechanical ventilation equipment. Noise levels from typical mechanical ventilation equipment range up to approximately 60 dBA Leq as measured at a distance of 25 feet. The building’s proposed mechanical ventilation units could be located as close as 30 feet from the nearest noise-sensitive receptor, which is the multi-family residential home located south of the proposed building. At this distance, noise levels generated by this equipment would attenuate to below 58.5 dBA Leq at this closest residential receptor. These noise levels would not exceed Contra Costa County’s or the City of Walnut Creek’s maximum exterior noise threshold for receiving residential land uses of 65 dBA DNL. They would therefore also not exceed the maximum interior noise threshold of 45 dBA DNL as measured inside the nearest residential receptor (Draft EIR, Section 3.11, Noise, Page 3.11-18–20).

Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with noise would be less than significant with mitigation incorporated. Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, could contribute to a cumulative impact related to traffic noise land use compatibility (Draft EIR, Section 3.11, Noise, Page 3.11-23). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.11, Noise, Page 3.11- 16). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures Implement MM NOI-1 above. Facts in Support of Findings Noise Land Use Compatibility Consistency Combined cumulative year traffic and BART activity noise levels at the project site would result in noise levels that Contra Costa County considers to be conditionally acceptable for new multi-family residential land uses (with projected noise levels of up to 74 dBA DNL at the highest impacted façade). This impact is potentially significant. However, as discussed under Impact NOI-1, MM NOI-1 shall be implemented, which requires the project to include a code compliant mechanical ventilation system that would permit windows to remain closed for prolonged periods, as well as upgraded window and door assemblies to ensure compliance with the interior noise standard of 45 dBA DNL. This measure would ensure that potentially impacted interior residential units would meet the interior noise level requirement of 45 dBA DNL. Therefore, implementation of MM NOI-1 would ensure that the project would not result in a cumulatively considerable contribution to consistency with noise land use compatibility standards (Draft EIR, Section 3.11, Noise, Page 3.11-23). Construction Noise Temporary Substantial Increase The geographic scope of the cumulative noise analysis is the project vicinity, including surrounding sensitive receptors. Noise impacts tend to be localized; therefore, the area near the project area (approximately 0.25 mile) would be the area most affected by proposed plan activities. However, none of the cumulative projects shown in Table 3-1 are located within 0.25 mile of the project site. Therefore, the cumulative impact is less than significant and the project would not have a cumulatively considerable contribution related to cumulative construction noise (Draft EIR, Section 3.11, Noise, Page 3.11-23).

Therefore, project-related traffic noise level would result in less than significant increases in traffic noise levels along modeled roadway segments in the project vicinity. This would be a less than significant impact, and no mitigation would be required. Given the above information, the project, in conjunction with other existing, planned, and probable future projects, would result in a less than significant cumulative impact related to noise (Draft EIR, Section 3.11, Noise, Page 3.11-23). Operational Stationary Noise Permanent Substantial Increase Implementation of the project would introduce new stationary noise sources to the ambient noise environment in the project vicinity, including new mechanical ventilation equipment. However, noise levels generated by this equipment would attenuate to below 58.5 dBA Leq at the closest residential receptor. These noise levels would not exceed documented existing background ambient noise levels. Therefore, implementation of the project would not result in a cumulatively considerable contribution to existing ambient noise conditions in the project vicinity (Draft EIR, Section 3.11, Noise, Page 3.11-24). Construction and Operational Vibration The only cumulatively considerable contribution to vibration conditions in the project vicinity would result from introduction of new permanent sources of groundborne vibration in the project site vicinity. The only major sources of groundborne vibration in the project vicinity is railroad activity along the rail line west of the project site. Implementation of the project would not introduce any new permanent sources of groundborne vibration to the project vicinity and would not increase railroad activity. Therefore, implementation of the project would not result in a cumulatively considerable contribution to vibration conditions in the project vicinity (Draft EIR, Section 3.11, Noise, Page 3.11-24). 1.6.9 - Public Services and Recreation Impact REC-2 The proposed project could include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-23). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-24). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures Implement MM AIR-2, MM AIR-3, and MM NOI-2 above.

The proposed project would include approximately 2.1 acres of private recreational facilities, including a central open space area, paseo and walkways, a dog park, and private yards. Impacts associated with the proposed amenities are analyzed in the discussion of air quality, energy, greenhouse gas (GHG) emissions, noise, and transportation-related impacts within the Draft EIR, which are explained in more detail as follows: • Air Quality: Less than significant impact with mitigation incorporated. Impact AIR-3 relates to sensitive receptors. Receptors include residences, schools and schoolyards, parks and playgrounds, daycare centers, nursing homes, and medical facilities. MM AIR-2 and MM AIR-3 would reduce construction impacts to a less than significant level. • Energy: Less than significant impact. • GHG Emissions: Less than significant impact. • Noise: Less than significant impact with mitigation incorporated. Impact NOI-2 relates to construction noise and applicable standards, and MM NOI-2 reduces impacts during construction to a less than significant level. • Transportation: Less than significant impact. Therefore, the proposed project’s construction of parks and recreational facilities on the project site would result in a less than significant impact with mitigation incorporated (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-24). The County finds that MM AIR-2, MM AIR-3, and MM NOI-2 are feasible, are adopted, and will further reduce impacts associated with Public Services and Recreation. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Public Services and Recreation would be less than significant with mitigation incorporated. 1.7 - No Significant and Unavoidable Impacts Identified As explained in the above Findings of Fact, all of the proposed project’s impacts on the environment would either be insignificant or, through the incorporation of mitigation measures, can be reduced to less than significant. The Lead Agency hereby finds that the proposed project would not result in any significant and unavoidable impacts. The incorporation of mitigation measures outlined in the Draft EIR and the attached MMRP would fully mitigate impacts to a less than significant level. Therefore, a Statement of Overriding Considerations is not required. Nonetheless, the County has considered the benefits of the proposed project in its determination on the project as discussed in the Draft EIR and these Findings. Having considered the entire administrative record on the proposed project, the County finds that the proposed project should be implemented. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 96 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx 1.8 - Findings Regarding Alternatives 1.8.1 - Introduction This section presents findings regarding alternatives to the proposed project. The section provides a summary and discussion of the feasibility of the following alternatives evaluated in the Draft EIR: • Alternative 1: No Project, No Build Alternative. • Alternative 2: Reopening the Palmer School Alternative. In accordance with CEQA Guidelines Section 15126.6, the Draft EIR contained a comparative impact assessment of alternatives to the proposed project. The primary purpose of this analysis is to provide decision-makers and interested agencies, organizations, and individuals with information about a reasonable range of potentially feasible project alternatives, which could avoid or reduce any of the proposed project ’s significant adverse environmental effects. Important considerations for this alternatives analysis are noted below: • An EIR need not consider every conceivable alternative to a project; • An EIR should identify alternatives that were considered by the lead agency, but rejected as infeasible during the scoping process; • Reasons for rejecting an alternative include: - Failure to meet most of the basic project objectives identified in Section 2, Project Description. - Infeasibility; and - Inability to avoid significant environmental effects. CEQA does not require that an analysis of alternate sites always be included in an EIR. Pursuant to CEQA Guidelines Section 15126.6(f)(2), in making the decision to include or exclude analysis of an alternate site, the “key question and first step in analysis is whether any of the significant effects of the proposed project would be avoided or substantially lessened by putting the proposed project in another location. Only locations that would avoid or substantially lessen any of the significant effects of the proposed project need to be considered for inclusion in the EIR.” During the alternatives review process, the County conducted a review of available land near I-680 and in close proximity to the Pleasant Hill/Contra Costa Centre BART station that could support a project similar in size and type as the proposed project, and that had an appropriate General Plan land use designation and zoning classification to allow for multi-family residential land uses. An appropriate alternative vacant site was not identified within the County limits in the general vicinity. Furthermore, CEQA confirms that whether a proponent can reasonably acquire, control, or otherwise have access to an alternative site is a key factor in determining whether an off-site alternative is potentially feasible (State CEQA Guidelines § 15126.6(f)). The County, as Lead Agency, is therefore not required to select an alternative site for the proposed project. Based on CEQA Guidelines Section 15126.6, a potential alternative location was rejected as infeasible (Draft EIR, Section 4.6.3, Alternative Location, Page 4- 21).

Under the No Project, No Build Alternative, the proposed project would not be constructed. The closed, vacant private school and its associated structures would remain on-site, and no development of any kind would occur. For the purposes of this alternatives analysis, it is assumed that the existing buildings would remain vacant and no educational, or other alternative, land use activities would occur. Findings Except for hazards and hazardous materials and land use and planning, the No Project, No Build Alternative would avoid all the proposed project’s less than significant impacts and less than significant impacts with mitigation described in Sections 3.1 through 3.16, as well as avoid the need to implement any mitigation measures. The No Project, No Build Alternative would result in greater impacts than the proposed project associated with hazards and hazardous materials; however, this impact would remain less than significant. Because this alternative would result in vacant and underutilized parcels inconsistent with land use and planning, it would result in a significant and unavoidable impact with respect to land use, which is a greater impact in comparison with the proposed project (Draft EIR, Section 4.3: Alternative 1 – No Project, No Build Alternative, Page 4-5). The No Project, No Build Alternative would not meet any of the project objectives because the project site would not be developed with 125 townhouse condominium units, including affordable units. Instead, the existing buildings on the project site would remain vacant and no educational land use activities would occur. As such, the No Project, No Build Alternative would not meet the objectives of developing an appropriate mix of multi-family units (including affordable units) that meets regional housing goals, providing affordable housing units in accordance with the Contra Costa County Housing Element (2014), locating housing in close proximity to transit in order to reduce VMT, providing housing with a variety of floor plans and unit types to enhance the economic viability of the development for long-term sustainability, replacing an obsolete private school with new market rate and affordable for-sale townhouse condominium homes consistent with the General Plan and surrounding neighborhood, and establishing physical and social connections between Jones and Oak Roads by building safe, private streets, walkable landscaped open spaces including stormwater management and green building components (Draft EIR, Section 4.3: Alternative 1–No Project, No Build Alternative, Page 4-6). Accordingly, based on the discussion in the EIR and all other evidence before it, the County finds that the No Project, No Build Alternative does not advance or meet any of the project objectives, and would result in greater impacts than the proposed project associated with land use and planning. The County rejects this alternative as infeasible. 1.8.3 - Alternative 2: Reopening the Palmer School Alternative. Under the reopening of the Palmer School Alternative, the currently closed school would reopen and resume operations as a private, nonsectarian, co-educational school, serving Junior Kindergarten to Eighth Grade students. All buildings and structures would remain in place, no trees would be removed, and no new development would take place on the project site. The school would resume operations at the same level as at the time of school closure in June 2020.

This process would include obtaining a land use permit from Contra Costa County. The school would continue its mission to offer an alternative to the larger class size and teacher ratio of public schools. The school would resume operating with a low student-to-faculty ratio and structured academic program that includes on-campus sports and community-based activities. Under this alternative, the school would return to its pre-closure enrollment of approximately 370- 400 students, employing approximately 45-52 staff members. School hours would follow pre-closure hours and would be open Monday through Friday, from 7:00 a.m. until 6:00 p.m., with grade-level specific hours as follows: Junior Kindergarten 8:30 a.m. to 11:30 a.m., Kindergarten 8:30 a.m. to 1:00 p.m., First Grade 8:30 a.m. to 2:00 p.m., Second and Third Grades 8:30 a.m. to 2:30 p.m., and Fourth through Eighth Grades 8:30 a.m. to 3:30 p.m. Consistent with the pre-closure schedule, students would be allowed on campus as early as 8:00 a.m. and could remain until 4:00 p.m. daily. An extended day program would be available before and after these hours (7:00 a.m. to 8:00 a.m. and 4:00 p.m. to 6:00 p.m.). The school would also host nighttime meetings for parents, scouting meetings, and other activities. Consistent with pre-closure activity, during the summer months, the school would offer a 10-week recreational program for children aged four to eleven years old. Activities would include arts and crafts, organized sports and games, nature study, cooking, science, swimming, camp songs and more. Summer camp would enroll approximately 100-160 students and employ approximately 25 staff members. The camp would operate Monday through Friday (with the exception of Independence Day observance) from 9:00 a.m. to 3:30 p.m. Extended day care would be offered before and after the camp hours similar to school days. Findings The Reopening the Palmer School Alternative would result in similar impacts to the proposed project’s less than significant impact without mitigation associated with population and housing, transportation, utilities and service systems, and wildfire. This alternative would lessen the severity of the proposed project’s less than significant with mitigation impacts associated with respect to aesthetics, biological resources, cultural and tribal cultural resources, geology and soils, hazards and hazardous materials, hydrology and water quality, and public services and recreation. This alternative would result in a greater, although still less than significant, impact related to energy and land use and planning. With respect to GHG emissions, this alternative would require mitigation where the proposed project would not, which would result in a greater impact than the proposed project. This alternative would result in similar or greater impacts with respect to noise. The Reopening the Palmer School Alternative would not meet any of the project objectives because the project site would not be developed with 125 multi-family residential units, including affordable units. Instead, the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, and no new development would take place on the project site. The school would resume operations at the same level as at the time of school closure in June 2020. As such, the Reopening the Palmer School Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 99 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Alternative would not meet the objectives of (1) developing an appropriate mix of multi-family units (including affordable units) that meets regional housing goals, (2) providing affordable housing units in accordance with the Contra Costa County Housing Element (2014), (3) locating housing in close proximity to transit in order to reduce VMT, (4) providing housing with a variety of floor plans and unit types to enhance the economic viability of the development for long-term sustainability, (5) replacing an obsolete private school with new market rate and affordable for-sale townhouse condominium homes consistent with the General Plan and surrounding neighborhood, (6) establishing physical and social connections between Jones and Oak Roads by building safe, private streets, walkable landscaped open spaces including stormwater management and green building components, (7) providing on-site open space amenities for future residents, and (8) phase development to allow for managed, orderly, and economically viable growth. This alternative would partially meet the objective related to retaining the architectural and visual character of the neighborhood because the on-site trees would not be removed (Draft EIR, Section 4.4: Alternative 1 –Reopening the Palmer School, Page 4-17). Accordingly, based on the discussion in the EIR and all other evidence before it, the County finds that the Reopening the Palmer School Alternative does not fully meet any of the project objectives. The County rejects this alternative as infeasible. 1.8.4 - Environmentally Superior Alternative Section 15126.6(e)(2) of the State CEQA Guidelines indicates that an analysis of alternatives to a proposed project shall identify an environmentally superior alternative among the alternatives evaluated in an EIR. Each of the two project alternatives would lessen the environmental impacts relative to the proposed project to a certain degree (as described above and further in the Draft EIR). If the No Project Alternative is the environmentally superior alternative—which is the case here as it avoids all project impacts but fails to satisfy any of the proposed project objectives—the EIR must also identify another environmentally superior alternative among the remaining alternatives. Overall, based on these Findings, the Reopening the Palmer School Alternative would be considered the environmentally superior alternative, even though it would fail to fully meet all of the project ’s objectives and is therefore infeasible. 1.9 - Findings Regarding Cumulative Impacts Consistent with CEQA’s requirements, the Draft EIR for the proposed project includes an analysis of cumulative impacts. The discussion of cumulative impacts in this subsection analyzes the cumulative impacts of the proposed project, taken together with other past, present, and reasonably foreseeable future projects producing related impacts. The goal of this analysis is to determine whether the overall long-term impacts of all such projects would be cumulatively significant and to determine whether the proposed project itself would cause a “cumulatively considerable” incremental contribution to any such cumulatively significant impacts. To determine whether the overall long-term impacts of all such projects would be cumulatively significant, the analysis generally considers the following: Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 100 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx • The area in which impacts of the proposed project would be experienced. • The impacts of the proposed project that are expected in the area. • Other past, proposed, and reasonably foreseeable projects that have had or are expected to have impacts in the same area. • The impacts or expected impacts of these other projects. • The overall impact that can be expected if the individual impacts from each project are allowed to accumulate. “Cumulative impacts” refers to two or more individual impacts that, when considered together, are considerable or that compound or increase other environmental impacts (CEQA Guidelines § 15355). Cumulative impacts can result from individually minor but collectively significant impacts taking place over time (40 Code of Federal Regulations [CFR] 1508.7). If the analysis determines that the potential exists for the project, taken together with other past, present, and reasonably foreseeable future projects, to result in a significant or adverse cumulative impact, the analysis then determines whether the project’s incremental contribution to any significant cumulative impact is itself significant (i.e., “cumulatively considerable”). The cumulative impact analysis for each individual resource topic is presented in each resource section of this chapter immediately after the description of the direct project impacts and identified mitigation measures. The Draft EIR evaluated potential cumulative impacts by considering the impacts of the proposed project, taken together with other past, present, and reasonably foreseeable future projects producing related impacts. CEQA defines cumulative impacts as “two or more individual effects which, when considered together are considerable” and suggests that cumulative impacts may “result from individually minor but collectively significant projects taking place over a period of time” (State CEQA Guidelines § 15355). Additional guidance on the significance of cumulative impacts is found in CEQA Guidelines Section 15065(a)(3) which provides that a project may be individually limited but have a “cumulatively considerable” impact when the “incremental effects of an individual project are significant when viewed in connection with the effects” of past, current, and probable projects. Cumulative projects are identified in Table 3-1 of the Draft EIR. The degree to which past projects are included within the list of projects is generally limited, due to the fact that past projects are included in the current environmental conditions already considered as part of the baseline and existing environmental setting. To address cumulative impacts, the Draft EIR includes a discussion of potential cumulative effects in each topical section. Specific findings for each topical area are made above in Sections 1.5 and 1.6 of this document. Based on the Draft EIR and the entire administrative record, the County finds that potentially significant cumulative impacts can be mitigated to less than significant levels and further finds that the project would not have any environmental impacts that are individually limited but cumulatively considerable. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 101 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx 1.10 - Findings Regarding Growth Inducement State CEQA Guidelines Section 15126.2(e) requires a discussion of the ways in which a proposed project could foster economic or population growth or the construction of additional housing, either directly or indirectly, in the surrounding environment. Typical growth-inducing factors might be the extension of urban services or transportation infrastructure to a previously unserved or underserved area or the removal of major barriers to development. Direct Population Growth The proposed project would develop 125 new townhouse condominium units on the project site and would add an estimated 357 persons to the County’s population. This would represent an increase of 0.2 percent relative to the unincorporated population of 174,423. This amount of population growth would be within the General Plan’s 2020 population and dwelling projections for the unincorporated area and, therefore, would not be considered substantial. Furthermore, it would also be within the ABAG 2020-2040 regional population growth projections. Impacts associated with direct population growth would be less than significant (Draft EIR, Section 5.2: Growth-Inducing impacts, Page 5-2). Indirect Population Growth The proposed project is exclusively residential; it would not create new permanent employment opportunities. Thus, no indirect population growth from new employment would occur. The project site has been developed since the 1930s and is located within an urbanized area of the unincorporated County. It is served with urban infrastructure and utilities including potable water, sewer, storm drainage, electricity, and natural gas. As such, the proposed project would not remove a barrier of growth through the extension of infrastructure or utilities to an unserved area. Impacts associated with indirect population growth would be less than significant (Draft EIR, Section 5.2: Growth-Inducing impacts, Page 5-2). 1.11 - Findings Regarding Significant Irreversible Environmental Changes According to Sections 15126(c) and 15126.2(d) of the State CEQA Guidelines, the Lead Agency address any significant irreversible environmental changes that would occur should the proposed project be implemented. Generally, a project would result in significant irreversible environmental changes if any of the following would occur: • The proposed project would involve a large commitment of nonrenewable resources; • The primary and secondary impacts of the proposed project would generally commit future generations to similar uses; • The proposed project involves uses in which irreversible damage could result from any potential environmental accidents; or • The proposed consumption of resources are not justified. The proposed project consists of the development of new infill multi-family residential uses on a site that currently supports a closed private school. The site is within an urbanized area of Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 102 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx unincorporated Contra Costa County adjacent to the Walnut Creek city limits and is zoned for residential use. Construction and demolition debris recycling practices would be expected to allow for the recovery and reuse of building materials such as concrete, lumber, and steel and would limit disposal of these materials, some of which are nonrenewable. Construction of the proposed project would include the consumption of resources that are not replenishable or which may renew so slowly to be considered nonrenewable. These resources would include the following: certain types of lumber and other forest products; aggregate materials used in concrete and asphalt such as sand, gravel, and stone; metals such as steel, copper, and lead; petrochemical construction materials such as plastics; and water. Fossil fuels such as gasoline and oil would also be consumed in the use of construction vehicles and equipment. Consumption of building materials and energy is common to most other development in the region, and commitments of resources are not unique or unusual to the proposed project. Development would not be expected to involve an unusual commitment of nonrenewable resources, nor be expected to consume any resources in a wasteful manner. At operation, day-to-day activities would involve the use of nonrenewable resources such as petroleum and natural gas during operations. The new buildings’ uses would be required to adhere to the latest adopted edition of the CBC, which includes a number of standards that would reduce energy demand, water consumption, wastewater generation, and solid waste generation that would collectively reduce the demand for resources. This would result in the emission and generation of less pollution and effluent and would lessen the severity of corresponding environmental effects. Although the proposed project would result in an irretrievable commitment of nonrenewable resources, the commitment of these resources would not be significantly inefficient, unnecessary, or wasteful. Finally, the proposed project is within walking distance of the Pleasant Hill/Contra Costa Centre BART station. At a normal walking pace, it would take approximately 5 minutes to walk from the project site to the BART station (Draft EIR, Section 3.14, Transportation, Page 3.14-17). It is also within walking distance of the Iron Horse Trail, and the Contra Costa Canal Trail and employment opportunities in Contra Costa Centre. Overall, the proposed project would be expected to result in less consumption of resources than a comparable residential project at the urban edge.

This information is provided in compliance with Public Resources Code Section 21081.6. Various documents, information, testimony, reports, studies, analyses, and other materials (both oral and written) constitute the record upon which the County bases these Findings and the basis for the Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 103 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx County ’s approval and/or adoption contained herein. These Findings cite specific pieces of evidence, but none of the County's findings are based solely on those cited pieces of evidence. Rather, these Findings are based upon the entire record, and the Lead Agency intends to rely upon all supporting evidence in the record for each of its conclusions contained herein. The documents in the record include all items referenced in Public Resources Code Section 21167.6(e): (i) All project application materials; (ii) The proposed project EIR (including the Draft EIR, the Final EIR, and all appendices attached thereto); (iii) All staff reports and related documents prepared by the lead agency and/or consultants with respect to the lead agency’s compliance with the substantive and procedural requirements of this division and with respect to the action on the proposed project; (iv) All staff reports and related documents prepared by the lead agency and written testimony or documents submitted by any person relevant to any findings or Statement of Overriding Considerations adopted by the lead agency pursuant to this division; (v) All documentary and oral evidence received and reviewed at public hearings, public meetings, study sessions, and workshops on the proposed project EIR, and any transcript or minutes of the proceedings at which any advisory body or decision-making body heard testimony on, or considered the proposed project EIR; (vi) All notices issued by the lead agency to comply with this division or with any other law governing the processing and approval of the proposed project; (vii) All written comments received in response to, or in connection with, the proposed project EIR, including comments on the Draft EIR; (viii) All written evidence or correspondence submitted to, or transferred from, the lead agency with respect to compliance with this division or with respect to the proposed project; (ix) Any proposed decisions or findings submitted to the decision-makers by lead agency staff, or the proposed project proponent, project opponents, or other interested agencies, organizations and/or individuals; (x) The documentation of the final decision, including the proposed project EIR and all documents, in addition to those referenced in paragraph (c), cited or relied on in the findings or in a Statement of Overriding Considerations adopted pursuant to this division; (xi) For documentary and informational purposes, all locally adopted land use plans and ordinances, including, without limitation, general plans, specific plans and ordinances, master plans together with environmental review documents, findings, mitigation monitoring programs, and other documentation relevant to planned growth in the area; (xii) Any other written materials relevant to the lead agency’s compliance with this division or to its decision on the merits of the proposed project, including any drafts of any environmental document or portions thereof, which have been released for public review, Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 104 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx and copies of studies or other documents relied upon in any environmental document prepared for the proposed project and either made available to the public during the public review period or included in the lead agency's files on the proposed project, and all internal agency communications, including staff notes and memoranda related to the proposed project or to compliance with this division; (xiii) The full written record before any inferior administrative decision-making body whose decision was appealed to a superior administrative decision-making body prior to the filing of litigation; and (xiv) Any additional items not included above if otherwise required by law. 1.13 - Recirculation Not Required During the public review period after the Draft EIR was published, the Lead Agency received one comment letter that did not raise any significant environmental issues requiring any changes to or clarifications of the EIR. The Lead Agency has considered all relevant information including the opinions and comments of interested agencies, organizations, and individuals. The Lead Agency finds that none of the following situations requiring recirculation identified in CEQA Guideline 15088.5 have occurred: 1. A new significant environmental impact that would result from the proposed project (or any alternative) or from a new mitigation measure proposed to be implemented. 2. A substantial increase in the severity of an environmental impact would result unless mitigation measures are adopted that reduce the impact to a level of insignificance. 3. A feasible project alternative or mitigation measure considerably different from others previously analyzed would clearly lessen the significant environmental impacts of the proposed project (or an alternative), but the proposed project's proponents decline to adopt it. 4. The Draft EIR was so fundamentally and basically inadequate and conclusory in nature that meaningful public review and comment were precluded. Based on the foregoing and as explained in more detail in the Final EIR, and having reviewed all the information in the record of proceedings, the Lead Agency hereby finds that there was no significant new information nor was there information that required recirculation of the EIR. The additional information merely clarifies or amplifies an adequate EIR.

Visual surveys will include trees within 100 feet of project construction activities. Prior to building demolition, the applicants for development on any project parcel shall ensure that a qualified Biologist (i.e., one familiar with the identification of bats and signs of bats) survey buildings proposed for demolition for the presence of roosting bats or evidence of bats. If no roosting bats or evidence of bats are found in the structure, demolition may proceed. If the Biologist determines bats are present, the Biologist shall exclude the bats from suitable spaces by installing one-way exclusion devices. After the bats vacate the space, the Biologist shall close off the space to prevent recolonization. Building demolition shall only commence after the Biologist verifies seven to 10 days later that the exclusion methods have successfully prevented bats from returning. To avoid impacts on non-volant (i.e., nonflying) bats, the Biologist shall only conduct bat exclusion and eviction from September 1 through March 31. Exclusion efforts shall be restricted during periods of sensitive activity. On-site inspection During tree removal and building removal MM BIO-1b: Migratory and Nesting Birds 1.

PROJECT FINDINGS FOR CONDITIONS OF APPROVAL FOR SUMMERHILL HOMES (APPLICANT) AND SAM MENDES, ET. AL (OWNERS): COUNTY FILES #CDRZ21- 03258, CDSD21-09559, CDDP21-03001 A. General Plan Growth Management Element Findings 1. Traffic: Implementation Measure 4-c under the Growth Management Program (GMP) of the County’s General Plan requires a traffic impact analysis be conducted for any project that is estimated to generate 100 or more AM or PM peak-hour trips. The project involves the construction of 125-unit townhouse condominiums and therefore, a Traffic Impact Assessment was prepared (TIA). According to the Contra Costa County Transportation Analysis Guidelines, a project is expected to result in a less-than-significant vehicle miles traveled impact if the proposed project is located within ½ mile of an existing major transit stop or an existing stop along a high-quality transit corridor. The Pleasant Hill BART station, which is an existing major transit stop, is located within ½ mile from the project site. In addition, there are bicycle and pedestrian facilities between the project site and the Pleasant Hill BART station. There are continuous sidewalks along Jones Road and Oak Road that connects to the project site and the Pleasant Hill BART station. Furthermore, a Transportation Demand Management Plan (TDM) is prepared as part of this project, which includes a range of TDM measures designed to reduce single-occupant vehicle trips and encourage residents to walk, bike or use transit services. The project is conditioned to require the review and approval of the TDM plan. The project generated traffic would access the site via a new driveway connecting to Jones Road. There will also be a proposed driveway that will connect to the project site on Oak Road. The new driveway on Jones Road will be 26 feet wide, which can accommodate two-way traffic. The site plan shows that the Oak Road driveway would be approximately 26 feet. The 26 feet driveway width will be adequate for emergency vehicle access. Overall,, the project would not cause unacceptable traffic related impacts in the immediate vicinity or area. 2. Water: Water supply would be provided to the proposed project by the CCWD. Because the project site is currently served by the CCWD, its water consumption is factored into the UWMP’s planning projections. Thus, adequate water supplies are available to serve the project and no new or expanded water treatment or Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 BOS, March 1, 2022 Page 2 of 8 conveyance facilities would be required. CCWD provided a letter to the applicant dated November 10, 2020, confirming it could serve the project and providing standard requirements for new service connections (e.g., separate metering of domestic, fire, and irrigation). Thus, adequate water supplies would be available to serve the project from existing and planned supplies. 3. Sanitary Sewer: The project is within the service area of the Central Contra Costa Sanitary District (CCCSD) who provides wastewater services for the project. A new on-site sewer collection system consisting of 8-inch diameter pipes that would discharge via service lateral to an existing 18-inch diameter sewer line in Jones Road would be installed for the project. The CCCSD provided comments to the applicant dated August 4, 2020, confirming it could serve the project providing standard requirements for new service connections (e.g., payment of connection fees). Thus, the CCCSD Treatment facility would have sufficient capacity to serve all aspects of the project. 4. Fire Protection: Four fire stations are located within approximately 2 miles of driving distance of the project site: Station No. 1, located at 1330 Civic Drive in Walnut Creek, is approximately 1.7 miles (driving distance) south of the project site; Station No. 2, located at 2012 Geary Road in Pleasant Hill, is approximately 1.4 miles (driving distance) west of project site, Station No. 5, located 205 Boyd Road in Pleasant Hill, is approximately 1.9 miles (driving distance) north of the project site; and Station No. 10, located at 2955 Treat Boulevard in Concord, is approximately 2.2 miles (driving distance) northeast of the project site. The DEIR prepared identified response time from Station No. 2 to the project site would be in 2 minutes and 24 seconds, which is under the 5-minute response standard set by the County’s General Plan. The project would comply with the California Building Standards Code (CBC), which is adopted by the Ordinance Code. In compliance with the California Fire Code, Part 9 of the CBC, during construction the project would follow standards for fire safety related to provision of fire apparatus access and acquisition of building permits. With an adequate fire engine response time to the project site, adherence to the CBC Codes, adequate project site access, and payment of impact fees to the CCCFPD, the project would Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 BOS, March 1, 2022 Page 3 of 8 not create a need to construct new or expand existing fire protection or emergency medical services facilities. 5. Public Protection: The County General Plan Policy 7-57 indicates a Sheriff facility standard of 155 square feet of Sheriff station space per 1,000 persons of population. The square footage of the Valley Station is estimated to be approximately 5,372 square feet. The proposed project would increase the population of unincorporated Contra Costa County by approximately 357 persons. Accordingly, the project would require 55 square feet of Sheriff station space. This increased demand for Sheriff station space represents approximately 1 percent of the Valley Station’s existing square footage and, thus, represents a nominal increase in demand. Additionally, the Office of the Sheriff did not indicate that the proposed project would result in the need for new or expanded Sheriff facilities in order to maintain acceptable service ratios, response times, or other performance objectives. As such, the project would not adversely affect service ratios or response times or increase the use of existing police protection facilities such that substantial physical deterioration, alteration, or expansion of these facilities would be required, thereby triggering environmental impacts. Furthermore, the Condition of Approval (COA) # 13 requires the formation of a police services district to provide funding to maintain and augment police services. 6. Parks and Recreation: As the project will add to the County’s population, COA #10 and 11 requires the project proponent to pay applicable Park fees per unit. The Park Impact fee collected will be used for acquisition of parkland and development of parks and recreational facilities. The Park Dedication requirement allows the developer of land for residential use to dedicate land, pay an in-lieu fee, or a combination of both for neighborhood and community park or recreational purposes. Furthermore, the project includes outdoor recreational amenities, such as a dog park and outdoor seating areas within the courtyards to be used by the residents of the development. 7. Flood Control and Drainage: The project is in Zone X, as designated on the Federal Emergency Management Agency’s Flood Insurance Rate Maps. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 BOS, March 1, 2022 Page 4 of 8 The project site is relatively flat, sloping gently northeast. Site drainage as proposed is directed to C.3 facilities and then conveyed to existing drainage lines along Jones Road and Oak Road. Prior to entering the existing the drainage is to be directed into hydromodification vaults. The existing drainage infrastructure in Jones Road and Oak Road are Line C and Line D-1 of Drainage 44B respectively. The site drainage may have to be revised to accommodate for the treatment of the proposed private roads. B. Rezoning Findings (County Code Section 26-2.1806) 1. Required Finding: The change proposed will substantially comply with the general plan. Project Finding: The project site is located within a Multiple-Family Residential- High Density (MH) General Plan land use designation. Primary land uses in the MH land use designation include attached single-family residences (such as duplexes or duets), multiple-family residences such as condominiums, town houses, apartments, and mobile home parks, and accessory buildings and structures normally auxiliary to the primary uses. The project is a use that is consistent with the MH land use designation. The project requires a rezone of the project site to a Planned Unit District (P-1) to allow 125-unit townhouse condominiums. Table 3-5 of the County’s General Plan indicates that a P-1 zoning district is consistent with the MH land use designation. The project is a transit-oriented and infill project that is consistent with other General Plan policies that promotes housing near the Pleasant Hill/Contra Costa Centre BART Station and encourages other modes of transportation (e.g., transit, bicycling), while providing additional units to the County’s housing inventory. Thus, the rezoning of the 5.94-acre project site will substantially comply with the County’s General Plan. 2. Required Finding: The uses authorized or proposed in the land use district are compatible within the district and to uses authorized in adjacent district. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 BOS, March 1, 2022 Page 5 of 8 Project Finding: The project site is approximately 0.25 miles south of the Pleasant Hill/Contra Costa Centre BART Station, and is surrounded by a number of multiple-family residential developments. The project is a use consistent with the MH General Plan land use designation. Overall, the project is in harmony with the surrounding area and the uses established in the area. 3. Required Finding: Community need has been demonstrated for the use proposed, but this does not require demonstration of future financial success. Project Finding: The 5.94-acre project site was the location of the former Palmer School for Boys and Girls, a private K-8 school that closed in 2020. The project is an infill project that is located within an area that is developed with multiple- family residential and office uses. The project to construct the 125 townhouse condominium units will improve the current vacant use of the project site. Further, the 2005-2020 Contra Costa County General Plan contains policies related to providing an adequate supply of housing and encouraging infill development on under-utilized sites within urbanized areas where necessary utilities already are installed. This project is consistent with the surrounding area consisting of residential development near transit. Furthermore, the project is consistent with the MH General Plan land use designation. C. Tentative Map Findings (County Code Section 94-2.806) 1. Required Finding: The advisory agency shall not approve a tentative map unless it finds that the proposed subdivision, together with the provisions for its design and improvement, is consistent with the applicable general plan required by law. Project Finding: The project is located within the unincorporated Walnut Creek community, where the surrounding uses include primarily of residential developments and office uses. The tentative map would subdivide the 5.94-acre project site into 19 residential lots to construct 19 buildings for a total of 125 townhouse condominium units. The project is consistent with the proposed General Plan land use designation of Multiple-Family Residential- High Density (MH), which allows 22.0 – 29.9 units per net acre. The net acreage for the 5.94- acre site is 4.71 acres. The project to construct 125 units allows a density of 26.5 units per net acre, which results in a density of within the MH density range. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 BOS, March 1, 2022 Page 6 of 8 Overall, the project is consistent with the applicable policies for the MH land use designation, as well as transportation and housing policies of the General Plan. 2. Required Finding: The advisory agency shall not approve a tentative map unless it shall find that the proposed subdivision fulfills construction requirements. Project Finding: The project will comply with the collect and convey regulations, storm drainage facilities, and design standards for private roads. Additionally, compliance with the California Building Code and all applicable County Ordinances is required for grading of the property and construction of residential buildings. D. Findings of Approval of P-1 Zoning District and Final Development Plan (County Code Section (84-66.1406) 1. Required Finding: The applicant intends to start construction within two and one- half years from the effective date of the zoning change and plan approval. Project Finding: The applicant has indicated that they intend to commence construction within 2 ½ years off the effective date of the zoning change and plan approval. 2. Required Finding: The proposed planned unit development is consistent with the County General Plan. Project Finding: The project site is located within a Multiple-Family Residential- High Density (MH) General Plan land use designation. Primary land uses in the MH land use designation include attached single-family residences (such as duplexes or duets), multiple-family residences such as condominiums, town houses, apartments, and mobile home parks, and accessory buildings and structures normally auxiliary to the primary uses. The project is a use that is consistent with the MH land use designation. The project requires a rezone of the project site to a Planned Unit District (P-1) to allow 125-unit townhouse condominiums. Table 3-5 of the County’s General Plan indicates that a P-1 zoning district is consistent with the MH land use designation. The project is a transit-oriented and infill project that is consistent with other General Plan policies that promotes housing near the transit such as Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 BOS, March 1, 2022 Page 7 of 8 the Pleasant Hill/Contra Costa Centre BART Station and encourages other modes of transportation (e.g., transit, bicycling), while providing additional units to the County’s housing inventory. Thus, the rezoning of the 5.94-acre project site will substantially comply with the County’s General Plan. The County’s General Plan provides Housing goals and policies that promote and encourage projects, such as this project within the unincorporated Walnut Creek area. Goal 6 of the County’s Housing Element identifies the need to provide adequate sites with the appropriate land use and zoning designations to accommodate the County’s share of regional housing. The project site was the former location of the Palmer School for Boys and Girls, which closed in June 2020. The project would provide 125-units on a site that is underutilized and located within ½ mile of the Pleasant Hill/Contra Costa Centre BART Station. The project includes the rezoning of the property to P-1, which is consistent with the General Plan Land Use designation of MH. Policy 3-8 of the General Plan encourages infilling of already developed areas, where new development is preferred to vacant or under-used sites within urbanized areas, which have necessary utilities installed. The County’s General Plan also provides Transportation goals and policies that supports the project. The project is a transit-oriented, infill development project that provides the much-needed housing units near the Pleasant Hill/Contra Costa Centre BART Station. Overall, the project is consistent with the County’s General Plan, especially the goal to reduce greenhouse gas emissions by providing housing within an area that provides multimodal access. 3. Required Finding: In the case of residential development, it will constitute a residential environment of sustained desirability and stability, and will be in harmony with the character of the surrounding neighborhood and community. Project Finding: The surrounding area consists of residential uses, primarily of multiple-family residential development. The 125-unit townhouse condominiums will consist of 48 three-bedroom units and 77 four-bedroom units ranging in size from 1,362 – 2,281 square feet of living area. The project site is located within an established neighborhood that consisting primarily of multiple-family development within ½ mile of the Pleasant Hill/Contra Costa Centre BART Station Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 BOS, March 1, 2022 Page 8 of 8 and walking distance to the Iron Horse Regional Trail. The project site is located within an area that is accessible to different modes of transportation (e.g. bicycle, transit, etc.). Overall, the proposed development will be in harmony with the surrounding area. 4. Required Finding: The development of a harmonious integrated plan justifies exceptions from the normal application of this code. Project Finding: The project site is 5.94 acres in size that is currently zoned Multiple-Family Residential (M-17 and M-19) and Single-Family Residential (R- 15). The MH General Plan land use designation permits multiple-family residences such as condominiums, town houses, and apartments, consistent with the project to establish 125 townhouse condominium units. Applying the required setbacks for the current zoning districts would not be feasible, as the 5.94-acre project site is smaller in size for the higher density that the site is planned for. Additionally, the project site has three different zoning districts, in which the R-15 zoning designation is not consistent with the MH General Plan land use designation. Directly northeast and directly south of the project site are developments that are also zoned a Planned Unit District (P-1). Overall, the project will remain for residential use consistent with surrounding area. E. Tree Permit Findings (County Code Section 816-6.8010) Required Finding: The Board of Supervisors is satisfied that the following factors as provided by County Code Section 816-6.8010 for granting a tree permit have been satisfied: 1. Reasonable development of the property will require the removal of 74 trees, relocation of one tree, and work within the dripline of an additional six trees will be necessary to construct the project. All feasible efforts have been made to retain the maximum number of trees, as well as, to preserve those trees, which are exceptional due to their visual prominence on the site. 2. Development of this project cannot be reasonably accommodated on other parts of the property due to the size of the project site.

Draft EIR/26480017 Sec00-03 Exec Summary.docx EXECUTIVE SUMMARY Purpose This Draft Environmental Impact Report (Draft EIR) is prepared in accordance with the California Environmental Quality Act (CEQA) to evaluate the potential environmental impacts associated with the implementation of the Contra Costa County Oak Road Townhouse Condominiums Project (State Clearinghouse No. 2021040684). This document is prepared in conformance with CEQA (Public Resources Code [PRC] § 21000, et seq.) and the CEQA Guidelines (California Code of Regulations [CCR], Title 14, § 15000, et seq.). The purpose of this Draft EIR is to inform decision makers, representatives of affected and responsible agencies, the public, and other interested parties of the potential environmental effects that may result from implementation of the proposed Oak Road Townhouse Condominiums Project (project). This Draft EIR describes potential impacts relating to a wide variety of environmental issues and methods by which these impacts can be mitigated or avoided. Project Summary Project Location The project site is located in the unincorporated Walnut Creek area of Contra Costa County. The site is bound by residential uses to the north and south, by Oak Road to the east with residential uses across Oak Road, and by Jones Road to the west and north. Office uses are located north of Jones Road, while Interstate 680 (I-680) is located directly west of Jones Road. The Contra Costa Canal is approximately 450–600 feet south of the project site. The nearest Bay Area Rapid Transit (BART) station (Pleasant Hill/Contra Costa Centre Station) is located approximately 0.35 mile northeast of the site. I-680 is located approximately 180 feet to the west. Project Description The proposed project includes construction of 125 townhouse condominium units located in 19 three-story townhome condominium buildings. The buildings would be approximately 37–43 feet in height to the ridgeline, although roof-top deck structures may extend up to 45 feet in height. The 5.94-acre site would be developed with a total of approximately 237,816 square feet of new habitable construction (293,139 total gross building square feet), resulting in a net density of 26.3 dwelling units per acre. As part of the proposed project, the existing eight parcels would be divided into 19 residential lots (1-19), ranging in size from 7,706 square feet to 17,294 square feet, as well as 13 street and court lots (A-M), ranging in size from 2,808 and 9,834 square feet. The building site coverage area would be a maximum of 50 percent of the site (approximately 129,373 square feet). Thirteen of the 125 townhouse condominium units (10 percent) would comply with the Americans with Disabilities Act (ADA). Five types of units are proposed, ranging in size from 1,362 to 2,250 square feet with attached 1- or 2-car garages, 3 to 4 bedrooms and 3 to 3.5 bathrooms. Contra Costa County–Oak Road Townhouse Condominiums Project Executive Summary Draft EIR ES-2 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec00-03 Exec Summary.docx A minimum of 25 percent of the project site (approximately 92,120 square feet) would function as common landscaped open space and private open space areas. Additional common features would include internal streets, courts, walkways, and drainage improvements. Off-site improvements would include installation of parking stalls along Oak Road and Jones Road. The proposed project would involve the demolition of all existing improvements currently present on-site, including buildings, foundations, asphalt, concrete, fence poles, and landscaping. These buildings and structures are associated with the former Palmer School for Boys and Girls, a private K- 8 school that closed in 2020. In addition, 74 on-site trees would be removed, and one valley oak (Quercus lobata) would be relocated within the site. Six trees are located adjacent to the property boundaries, and have canopies that extend onto the site. Although construction activities would occur within the drip lines of these trees, they would be afforded protection during construction to ensure their preservation. The trees would be pruned in accordance with arborist recommendations to reduce the size of tree crown over the project site. Off-site improvements would include frontage sidewalk, driveway curb, gutter improvements including retaining existing on-street parking and street tree planting. Project Objectives The objectives of the proposed project are to: • Develop an appropriate mix of multi-family units (including affordable units) that meets the existing General Plan land use designation and regional housing goals. • Provide affordable housing units in accordance with the Contra Costa County Housing Element (2014). • Locate housing in close proximity to transit in order to reduce vehicle miles traveled. • Provide housing with a variety of floor plans and unit types to enhance the economic viability of the development for long term sustainability. • Retain the architectural and visual character of the neighborhood by building 3-story townhouse condominiums with roof-deck elements on selected homes fronting Oak Road and providing replacement landscaping that will mature over time. • Replace an obsolete private school with new market rate and affordable for-sale townhouse condominium homes consistent with the General Plan and surrounding neighborhood. • Establish physical and social connections between Jones and Oak Roads by building safe, private streets, walkable landscaped open spaces including stormwater management and green building components. • Provide on-site open space amenities for future residents. • Phase development to allow for managed, orderly, and economically viable growth.

Summary of Project Alternatives Below is a summary of the alternatives to the proposed project considered in Section 4, Alternatives to the proposed project. No Project Alternative: Under the No Project Alternative, the proposed 125-unit 19-building community proposed would not be constructed on the project site. The closed, vacant private school and its associated structures would remain on-site, and no development of any kind would occur. In this scenario, off-site improvements would not occur, trees would not be removed or impacted, grading would not take place, and the eight parcels would not be divided into 19 residential lots and 13 street and court lots. For the purposes of this alternatives analysis, it is assumed that the existing buildings would remain vacant and no educational land use activities would occur. This alternative would not require rezoning, a Final Development Plan, or Tree Permits. Re-open the Palmer School Alternative: Under the Re-opening the Palmer School Alternative, the currently closed school would re-open and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, and no new development would take place on the project site. The school would resume operations at the same level as at the time of school closure in June 2020. This alternative would not require rezoning, a Final Development Plan, or Tree Permits. Areas of Controversy Pursuant to CEQA Guidelines Section 15123(b), a summary section must address areas of controversy known to the lead agency, including issues raised by agencies and the public, and it must also address issues to be resolved, including the choice among alternatives and whether or how to mitigate the significant effects. A Notice of Preparation (NOP) for the proposed project was issued on April 28, 2021. The NOP describing the original concept for the project and issues to be addressed in the EIR was distributed to the State Clearinghouse, responsible agencies, and other interested parties for a 30-day public review period extending from April 29, 2021, through May 28, 2021. The NOP identified the potential for significant impacts on the environment related to the following topical areas: • Aesthetics • Air Quality • Biological Resources • Cultural Resources • Geology and Soil • Greenhouse Gas Emissions • Hazards and Hazardous Materials • Hydrology and Water Quality • Noise • Transportation Contra Costa County–Oak Road Townhouse Condominiums Project Executive Summary Draft EIR ES-4 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec00-03 Exec Summary.docx Disagreement Among Experts This Draft EIR contains substantial evidence to support all the conclusions presented herein. It is possible that there will be disagreement among various parties regarding these conclusions, although the Contra Costa County is not aware of any disputed conclusions at the time of this writing. Both the CEQA Guidelines and case law clearly provide the standards for treating disagreement among experts. Where evidence and opinions conflict on an issue concerning the environment, and the lead agency knows of these controversies in advance, the EIR must acknowledge the controversies, summarize the conflicting opinions of the experts, and include sufficient information to allow the public and decision makers to make an informed judgment about the environmental consequences of the proposed project. Potentially Controversial Issues Below is a list of potentially controversial issues that were raised during the NOP public review period and may be reiterated during the public review and hearing process of this Draft EIR: • Aesthetic impacts to views from adjacent residences should be evaluated. • Impacts to Biological Resources due to the removal of a large number of trees, including valley oaks (Quercus lobata), should be evaluated. • Land Use and Planning impacts due to size of setbacks between the proposed project buildings and adjacent residences should be evaluated. It is also possible that evidence will be presented during the 45-day, statutory Draft EIR public review period that may create disagreement. Decision makers would consider this evidence during the public hearing process. In rendering a decision on a project where there is disagreement among experts, the decision makers are not obligated to select the most environmentally preferable viewpoint. Decision makers are vested with the ability to choose whatever viewpoint is preferable and need not resolve a dispute among experts. In their proceedings, decision makers must consider comments received concerning the adequacy of the Draft EIR and address any objections raised in these comments. However, decision makers are not obligated to follow any directives, recommendations, or suggestions presented in comments on the Draft EIR, and can certify the Final EIR without needing to resolve disagreements among experts. Public Review of the Draft EIR Upon completion of the Draft EIR, the Contra Costa County filed a Notice of Completion (NOC) with the State Office of Planning and Research to begin the public review period (PRC § 21161). Concurrent with the NOC, this Draft EIR has been distributed to responsible and trustee agencies, other affected agencies, surrounding cities, and interested parties, as well as all parties requesting a copy of the Draft EIR in accordance with Public Resources Code 21092(b)(3).

In accordance with Sections 21067, 15367, and 15050–15053 of the CEQA Guidelines, Contra Costa County (County) is the lead agency under whose authority this document has been prepared. As an informational document, this Draft EIR is intended for use by the County and other public agency decision makers and members of the public in evaluating the potential environmental impacts of the proposed project. 1.1 - Project Overview The 5.94-acre project site consists of eight parcels and is located at 2740 Jones Road, southeast of the intersection of Interstate 680 and Treat Boulevard, within unincorporated Contra Costa County and adjacent to the City of Walnut Creek (see Exhibits 2-1 and 2-2). The project site was formerly used by the Palmer School for Boys and Girls, a private K-8 school, and is currently developed with 14 buildings as well as associated structures, including classrooms, an auditorium, a front office, a paved courtyard, a grass field, tennis courts, basketball courts playgrounds, a swimming pool, parking lots and planters. The private school operated from 1939 until its closure due to COVID-19 in June 2020. The proposed project includes rezoning of the project site from Multiple-Family Residential (M-17 and M-29) and Single-Family Residential (R-15) to a Planned Unit District (P-1) and approval of a vesting tentative map reconfiguring the current eight parcels into 19 new residential parcels. The proposed project would involve a development plan to allow the demolition of all existing improvements currently present on-site, including buildings, foundations, asphalt, concrete, fence poles, and landscaping. The major project components are as follows: • Construction of 19 new three-story buildings containing 125 condominium units. • Approximately 237,816 square feet of new residential living area (293,139 total gross building square feet). • Removal of approximately 74 trees, relocation of one valley oak tree (Quercus lobata), and work within the dripline of an additional six trees. • Approximately 92,120 square feet of landscaped areas. • 278 on-site auto parking spaces. • Internal private streets, courts, walkways, and drainage improvements. • Off-site improvements would include frontage sidewalk, driveway curb, gutter improvements including retaining existing on-street parking and street tree planting.

The purpose of an EIR is to provide public agencies and members of the public with detailed information regarding the environmental effects associated with implementing a project. An EIR should analyze the environmental consequences of a project, identify ways to reduce or avoid the proposed project’s potential environmental effects, and identify alternatives to the proposed project that can avoid or reduce impacts. Pursuant to CEQA, public agencies must consider the environmental consequences of projects over which they have discretionary authority. This Draft EIR provides information to be used in the planning and decision-making process. It is not the purpose of an EIR to recommend approval or denial of a project. Before approval of the proposed project, the County, as lead agency and the decision-making entity, is required to certify that this EIR has been completed in compliance with CEQA, that the information in the EIR has been considered, and that the EIR reflects the independent judgment of the County. Pursuant to CEQA, decision makers must balance the benefits of a project against its unavoidable environmental consequences. If environmental impacts are identified as significant and unavoidable, the County may still approve the proposed project if it finds that social, economic, or other benefits outweigh the unavoidable impacts. The County would then be required to state in writing the specific reasons for approving the proposed project, based on information in the EIR and other information sources in the administrative record. This reasoning is called a “statement of overriding considerations” (PRC § 21081; CEQA Guidelines § 15093). In addition, the County as lead agency must adopt a Mitigation Monitoring and Reporting Program (MMRP) describing the measures that were made a condition of project approval to avoid or mitigate significant effects on the environment (PRC § 21081.6; CEQA Guidelines § 15097). The MMRP is adopted at the time of project approval and is designed to ensure compliance with the project description and EIR mitigation measures during and after project implementation. If the County decides to approve the proposed project, it would be responsible for verifying that the MMRP for this proposed project is implemented. The EIR will be used primarily by the County during approval of future discretionary actions and permits. This Draft EIR provides a project-level analysis of the environmental effects of the proposed project. The environmental impacts of the proposed project are analyzed in this Draft EIR to the degree of specificity appropriate, in accordance with CEQA Guidelines Section 15146. This Draft EIR addresses the potentially significant adverse environmental impacts that may be associated with the planning, construction, or operation of the project. It also identifies appropriate and feasible mitigation measures and alternatives that may be adopted to significantly reduce or avoid these impacts. CEQA requires that an EIR contain, at a minimum, certain specific components. These components are contained in this EIR and include the following: • Table of Contents • Introduction • Executive Summary Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Introduction FirstCarbon Solutions 1-3 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec01-00 Introduction.docx • Project Description • Environmental Setting • Significant Environmental Impacts • Mitigation Measures • Cumulative Impacts • Significant Unavoidable Adverse Impacts • Alternatives to the Proposed Project • Growth-Inducing Impacts • Effects Found not to be Significant • Areas of Known Controversy Contra Costa County is the lead agency for the project. CEQA Guidelines Section 15367 defines the lead agency as “. . . the public agency, which has the principal responsibility for carrying out or approving a project.” Other public agencies may use this Draft EIR in the decision-making or permit process and consider the information in this Draft EIR along with other information that may be presented during the CEQA process. This Draft EIR was prepared by FirstCarbon Solutions (FCS), an environmental consultant. Prior to public review, it was extensively reviewed and evaluated by the County. This Draft EIR reflects the independent judgment and analysis of the County as required by CEQA. Lists of organizations and persons consulted, and the report preparation personnel is provided in Chapter 7 of this Draft EIR. 1.3 - Purpose and Legal Authority 1.3.1 - Notice of Preparation and Public Scoping Process In accordance with Sections 15063 and 15082 of the CEQA Guidelines, the County, as lead agency, sent the Notice of Preparation (NOP) to responsible and trustee agencies, and interested entities and individuals on April 28, 2021, thus beginning the formal CEQA scoping process. The purpose of the scoping process is to allow the public and government agencies to comment on the issues and provide input on the scope of the EIR. The scoping period began on April 28, 2021, and ended on May 28, 2021, representing the statutory 30-day public review period. Fifteen comment letters and emails were received in response to the NOP. The NOP, comment letters, and emails are contained in Appendix A. A summary of comments submitted is provided in Table 1-1, with cross-references to applicable Draft EIR sections where comments are addressed. Pursuant to Section 15083 of the CEQA Guidelines, the County held a public scoping meeting on May 17, 2021, starting at 3:30 p.m. via a videoconference platform. At the meeting, attendees were given an opportunity to provide comments and express concerns about the potential effects of the project.

Contra Costa County is bordered by Alameda County to the south, Solano County to the north, San Joaquin County to the east, and Sacramento County to the northeast. The purpose of this Draft Environmental Impact Report (Draft EIR) is to identify potential environmental impacts of the proposed Oak Road Townhouse Condominiums Project (referred to herein as the proposed project) within unincorporated Walnut Creek. This Chapter provides a detailed overview of the project site location and setting, project objectives, project details, characteristics, and construction phasing. It also describes the intended uses of the Draft EIR by agencies with approval and permitting authority over the proposed project, as well as required approvals and permits. 2.1 - Project Location and Setting 2.1.1 - Location Regional Location Contra Costa County (County) is located in the eastern San Francisco Bay Area of California. The County is bordered to the north by Solano County, to the east by San Joaquin County, to the south by Alameda County, and to the west by Marin County and San Pablo Bay (Exhibit 2-1). The County covers 716 square miles and has historically been a suburban community serving major employment centers to the west and south. Major roadway networks including State Route (SR) 4, SR-24, SR-160, SR-242, Interstate 680 (I-680), Interstate 580 (I-580), and Interstate 80 (I-80) provide regional access to surrounding areas. I-680 is a north/south, 12-lane highway that is the main point of access connecting the County to eastern Bay Area cities. I-80 is a north/south highway that provides access to the western portions of the County and connections to the rest of the San Francisco Bay Area. The Richmond-San Rafael Bridge (I-580), which accommodates two westbound lanes on the upper level and two to three eastbound lanes on the lower level, provides a connection between Contra Costa and Alameda Counties and Marin County. Local Setting The project site is located at 2740 Jones Road, southeast of the intersection of I-680 and Treat Boulevard (Exhibit 2-2). The site is within the unincorporated County, but is also within the City of Walnut ’s Creek Sphere of Influence (SOI). The project site is surrounded to the east by the City of Walnut Creek, to the north by unincorporated County, to the west by I-680 and the City of Walnut Creek beyond it, and south by unincorporated County, the Contra Costa Canal, and the City of Walnut Creek (Exhibit 2-2). Specifically, the project site is located within the Briones Valley, California United States Geological Survey (USGS) 7.5-minute Topographic Quadrangle Map (Latitude 37° 55' 26.41" North; Longitude 122° 3' 32.14" We st).

Office uses are located north of Jones Road, while I-680 is located directly west of Jones Road. The Contra Costa Canal is approximately 470 feet south of the project site. The nearest Bay Area Rapid Transit (BART) station (Pleasant Hill/Contra Costa Centre Station) is located approximately 0.35 mile northeast of the site. I-680 is located approximately 180 feet to the west. 2.1.2 - Existing Project Site Characteristics The 5.94-acre project site is relatively flat (approximately 90 to 95 feet above mean sea level), with a topographic gradient that slopes gently to the northeast. The site is developed with structures associated with the former Palmer School for Boys and Girls, a private K-8 school for approximately 400 students that operated from 1939 until its closure due to COVID-19 in June 2020.1 Exhibit 2-5 depicts the location of existing buildings and structures. The former school consists of 14 vacant buildings as well as associated structures, including classrooms, an auditorium, a front office, a paved courtyard, a grass field, tennis courts, basketball courts playgrounds, a swimming pool, parking lots and planters. Multiple storage sheds are present on the school site. After the school closure, the classrooms, located in the southern portion of the school site, are generally empty or used as storage rooms for classroom materials. Situated outside of the classrooms are rows of lockers, bathrooms, and a janitorial supply closet with a functioning boiler. A landscaped area is located behind the classrooms along the southern boundary of the property and includes planter boxes, storm drain lines, power boxes, and a partially uncovered pipe that appears to be related to storm drainage. In the southeast corner of the property is a 2-story auditorium formerly used as a storage area, containing a kitchen, stage, water heater, and empty storage rooms on the second floor.2 Several of the existing structures in the northern portion of the project site have been associated with residential uses, including those at 2771, 2747, and 2751 Oak Road. All but two of these structures were previously converted into storage areas for the school. To the east of these buildings is an unpaved lot and a paved driveway. These units are occupied by the property owners’ family members who provide caretaker security services for the property and existing improvements. These units will be vacated in conjunction with the applicant’s acquisition of the property. No other buildings are occupied and are vacant. The project site consists of eight parcels, as shown in Exhibit 2-6 and Table 2-1.

Primary vehicular access would be provided from main driveways on Jones and Oak Roads, which would also provide for emergency vehicle access. A minimum of 25 percent of the project site (approximately 92,120 square feet) would function as common landscaped open space and private open space areas. Additional common features would include internal streets, courts, walkways, and drainage improvements. Off-site improvements would include installation of parking stalls along Oak Road and Jones Road. The proposed project would involve the demolition of all existing improvements currently present on-site, including buildings, foundations, asphalt, concrete, fence poles, and landscaping. In addition, 74 on-site trees would be removed, as shown in Exhibit 2-8, and one valley oak (Quercus lobata) would be relocated within the site, as shown in Exhibit 2-9. Six trees are located adjacent to the property boundaries, as shown in Exhibit 2-8, and have canopies that extend onto the site. Although construction activities would occur within the drip lines of these trees, they would be afforded protection during construction to ensure their preservation. The trees would be pruned in accordance with arborist recommendations to reduce the size of tree crown over the project site.8 2.3.1 - Proposed Land Use Designation and Zoning As described previously and shown on Exhibit 2-4 and Table 2-2, the project site is designated as Multiple-Family Residential–High Density (MH). As part of project approvals, the applicant is requesting rezoning of the site to Planned Unit District (P-1). As stated in Section 84-66.204 of the Ordinance Code, the intent of the P-1 Zoning District is to allow “diversification in the relationship of various uses, buildings, structures, lot sizes and open space while insuring [sic] substantial compliance with the General Plan and the intent of the Ordinance Code in requiring adequate standards necessary to satisfy the requirements of the public health, safety and general welfare. These standards shall be observed without unduly inhibiting the advantages of large-scale or special area planning.”9 As summarized in Table 2-3, Section 84-66.602 establishes requirements for new and alterations to existing land uses, structures, and site development within the P-1 Zoning District. Table 2-3: P-1 Zoning District Development Standards Development Feature Requirement Area (Minimums) Residential 5 acres for residential uses except that a mobile home subdivision shall have a minimum of 10 acres. Nonresidential 10 acres for nonresidential uses. 8 Hort Science–Bartlett Consulting. 2021. Tree Report Oak Road Townhome Condominiums. January 11. 9 Contra Costa County.

Source: Contra Costa County Ordinance Code, Sections 84-66.6 and 84-66.8. Section 84-66.1402 of the Contra Costa County Ordinance Code establishes the following Design Objectives for the P-1 Zoning District: 1. Building bulk, height, land coverage, visual appearance from adjacent land, and design compatibility with existing adjoining development and land which will remain, shall be considered, and controlled. 2. A development's design should successfully integrate individual buildings and building groups with the surrounding development, other physical features in the area, and existing development which will remain. 3. The design of structures should provide for harmonious composition of mass, scale, color, and textures, with special emphasis on the transition from one building type to another, termination of groups of structures, relationships to streets, exploitation of views, and integration of spaces and building forms with the topography of the site and the urban or suburban character of the area. 4. Provisions are to be made for an efficient, direct, and convenient system of pedestrian circulation, together with landscaping and appropriate treatment of any public areas or lobbies. 5. Off-street parking and loading areas should be integrated into the overall vehicular circulation system. 2.3.2 - Circulation and Access Vehicle Jones Road and Oak Road border the project site. Jones Road is a two-lane public street that runs north/south along the site’s western boundary. Oak Road is a four-lane public street that runs north/south along the site’s eastern boundary. Primary access to the site would be from two driveways: one along Jones Road and one along Oak Road.

The Contra Costa Canal Trail provides a good bicycle connectivity to the project site and to Seven Hills School. Pedestrian Within the vicinity of the project site, sidewalks currently exist along both side of Oak Road and Treat Boulevard, and along the east side of Jones Road, allowing residents of the proposed project to easily walk to the Pleasant Hill BART station. The traffic signal at the Oak Road/Jones Road and Oak Road/Treat Boulevard intersections includes crosswalks with pedestrian signal heads to facilitate crossing the street. There are no proposed City or County pedestrian improvement plans along Jones Road or Oak Road along the project frontage, and the project would not affect existing or planned pedestrian facilities. The Contra Costa Canal Trail and the Iron Horse Regional Trail serve pedestrian and cyclists. The Seven Hills School is located within a 1.5-mile radius (via the Contra Costa Canal Trail) of the project site. 2.3.3 - Design, Landscaping, and Lighting Building Design and Height The proposed project would include 19 three-story buildings, including three buildings on Oak Road with roof decks. Building height will range from 37 feet to a maximum of 43 feet; buildings with a roof-top deck may extend up to 45 feet in height. The buildings will be setback 15 feet from Jones Road and 10 feet from Oak Road. Exterior features of the buildings would include board and batten sidings, horizontal fiber cement lap siding, exterior plaster, architectural composition roofing shingles, metal awnings, vinyl windows, and painted metal railing. The exterior color palate would be comprised of whites and grays. Exhibit 2-11a through 2-10j show building elevations. Landscaping The project proposes a total of approximately 92,120 square feet of landscaped area (25 percent of the site), including a central open space area, paseo/walkways, a dog park, and private yards (see Exhibit 2-9). Plant material will be selected to emphasize water conservation and reduced maintenance. A maximum of 25 percent of non-turf plants will have a moderate irrigation water requirement and a minimum of 50 percent of non-turf plants will have a low to very low irrigation water requirement. A fully automated irrigation system would utilize water conserving methods. Irrigation would be installed throughout proposed bioretention areas to provide supplemental irrigation in the dry months with reduced irrigation during seasonal rainfall or wet months. Internal courtyards between buildings would be lined with trees, and the central open space would be surrounded by trees. Trees would also be installed along all sides of the project site boundary, including a combination of evergreen screen trees and flowering accent trees of varying sizes.

Lighting and Signage A monument sign is proposed at the entrance from Oak Road. The monument sign would include metal letters atop a 4-foot wall with a stone veneer finish. An 11-foot-tall structure, with pitched roof and siding matching the general architecture of the residential buildings, would be installed adjoining this wall, and a plaque with the Oak Road logo would be installed on this structure. Proposed lighting would include exterior lighting for the buildings and pole-mounted lighting throughout the parking areas. Specifically, exterior lighting would include four new street lights along the Oak Road frontage, matching existing street lights along this street; eight private street pole lights near the two project entrances and along the public streets and sidewalks, approximately 20 feet tall with shielding to direct lighting downward; forty 3.5-foot bollard lights strategically located throughout the site along pathways, common open space and paseos; and 125 wall pack lights above the garages for each home, to illuminate the driveways. Additionally, each of the 125 residential units would have a front porch light that would be operated by the owners. 2.3.4 - Infrastructure Improvements Domestic Water The Contra Costa Water District would supply the project site with potable water. An existing 12-inch water line is located along Oak Road east of the project site, and an existing 8-inch water line is located along Jones Road, west and north of the project site. The proposed project would include several 6- inch water lines that would be placed between buildings. These water lines would connect to a set of 10-inch water lines that would encircle the central buildings (P, Q, R, and S). These 10-inch lines would then connect the proposed project to the existing water lines on Oak Road and/or Jones Road. Four fire hydrants serve the project site: • At the corner of Street B and Court C, in close proximity to the Oak Road entrance. • At the corner of Street D and Court C, adjacent to Building K. • Toward the west end of Street D, between Buildings P and S. • At the corner of Street A and Street B, adjacent to Building P. Stormwater Drainage Contra Costa County Public Works would serve the project site. The project site is located within Drainage Area (DA) 44B. The project site is generally flat, with gentle slopes to the northeast toward Oak Road as well as to the northwest toward Jones Road. The southwestern portion of the site slopes toward Jones Road.

The proposed project would include the construction of a network of 12-inch to 18-inch storm drains, connecting it to these existing storm drains in Jones Road or Oak Road. On-site storage facilities of approximately 2,800 cubic feet would be needed to mitigate the potential increase in stormwater flows generated by the proposed project and to meet the hydromodification requirements. The proposed storm drain system would include the installation of two underground storage vaults to capture, store, and release the storm flow generated by the proposed project into the existing off-site storm drainage facilities. These two vaults would be placed at the downstream ends of the on-site storm drains at the respective discharge points at Oak Road and Jones Road.13 Several bioretention areas for stormwater treatment would be constructed throughout the project site. Trash capture devices would be installed on each stormwater inlet. Sanitary Sewer Utility infrastructure for the project site is anticipated to include connections to the existing Contra Costa County’s sanitary sewer system, which is operated by the Central Contra Costa County Sanitary District (Central San). Existing lateral connections would be replaced by a new on-site public main and laterals. An existing 6-inch sanitary sewer line is located within Oak Road east of the project site, an existing 8- inch line is located within Jones Road north of the project site, and an existing 18-inch line is located within Jones Road west of the project site. The new on-site mains and laterals would connect to the existing 18-inch sewer lines in Jones Road. Solid Waste and Recycling Collection The Central Contra Costa Solid Waste Authority (RecycleSmart) provides solid waste and residential recycling services for areas within Contra Costa County. RecycleSmart holds franchise agreements with waste franchises that provide solid waste collection and disposal of residential and commercial solid waste. RecycleSmart would provide solid waste and recyclable materials removal services for the project site. RecycleSmart is contracted with Republic Services for the collection, transfer, and disposal of residential and commercial garbage, recycling, and organics, through a contract with Mount Diablo Recycling for the processing of residential and commercial recycling materials.14 An area for waste, recycling, and green bins would be located in the garages, and a set of all three bins would be provided for each unit. 12 Ruggeri Jensen Azar. 2021.

The discussions of the environmental setting describe the present physical conditions, or baseline conditions, in the project area. The baseline used for the analysis of environmental impacts under the California Environmental Quality Act (CEQA) reflects the conditions present at the time the Notice of Preparation (NOP) for this Draft Environmental Impact Report (Draft EIR) was published. The potential impacts of the proposed project are compared against the existing baseline conditions for each environmental resource. Issues Addressed in this Draft EIR The proposed project is analyzed in this Draft EIR with respect to the following 16 environmental resource areas: • Aesthetics, Light, and Glare • Air Quality • Biological Resources • Cultural Resources and Tribal Cultural Resources • Energy • Geology and Soils • Greenhouse Gas Emissions • Hazards and Hazardous Materials • Hydrology and Water Quality • Land Use and Planning • Noise • Population and Housing • Public Services and Recreation • Transportation • Utilities and Service Systems • Wildfire Format of the Environmental Analysis Each resource area analyzed in this chapter includes the subsections summarized below. Introduction This subsection summarizes what will be discussed in the respective environmental topic section, states what informational documents are used as the basis for the section, and indicates what related comments, if any, were received during the EIR public scoping period. Environmental Setting This subsection describes the existing, baseline physical conditions of the project site and surroundings (e.g., existing land uses, transportation conditions, noise environment) with respect to each resource topic at the time the NOP was issued. Conditions are described in sufficient detail and breadth to allow a general understanding of the environmental impacts of the proposed project.

Impacts and Mitigation Measures This subsection evaluates the potential for the proposed project to result in direct and indirect adverse impacts on the existing physical environment, with consideration of both short-term and long-term impacts. The analysis covers all phases of the proposed project, including construction and operation. The significance thresholds for environmental impacts are defined at the beginning of this subsection, and the discussion of the approach to the analysis explains how the significance thresholds have been applied to evaluate the impacts of the proposed project. Indirect impacts are discussed only for those resources for which they have the potential to occur (e.g., cultural resources, air quality, and biological resources). Both project-level and cumulative impacts are analyzed. Project-level impacts could result from actions related to implementation of the project. Cumulative impacts could result from implementation of the proposed project in combination with other cumulative projects in the study area. As discussed in “Cumulative Impacts,” below, the projects listed in Table 3-1, in conjunction with the proposed project, are considered the cumulative scenario for the analysis of cumulative impacts. Impacts are analyzed and the respective assessment and findings are included in this Draft EIR, applying the following levels of significance: • No impact. A conclusion of “no impact ” is reached if no potential exists for impacts or if the environmental resource does not occur in the project area or the area of potential impacts. • Less than significant impact. This determination applies if the impact does not exceed the defined significance criteria or would be eliminated or reduced to a less than significant level through compliance with existing local, State, and federal laws and regulations. No mitigation is required for impacts determined to be less than significant. • Less than significant impact with mitigation. This determination applies if the proposed project would result in a significant impact, exceeding the established significance criteria, but feasible mitigation is available that would reduce the impact to a less than significant level. • Significant and unavoidable impact. This determination applies if the proposed project would result in an adverse impact that exceeds the established significance criteria, and no feasible mitigation is available to reduce the impact to a less than significant level. Therefore, the residual impact would be significant and unavoidable. • Significant and unavoidable impact with mitigation. This determination applies if the proposed project would result in an adverse impact that exceeds the established significance criteria, and although feasible mitigation might lessen the impact, the residual impact would be significant, and, therefore, the impact would be unavoidable.

Context is related to the uniqueness of a resource; intensity refers to the severity of the impact. Where applicable, Best Management Practices (BMPs) or project improvement measures, or both, are incorporated into the proposed project to limit the potential for a significant impact. Where necessary, mitigation measures are identified for significant impacts to limit the degree or lower the magnitude of the impact; rectify the impact by repairing, rehabilitating, or restoring the affected environment; or compensate for the impact by replacing or providing substitute resources or environments. These impacts conclude with a finding of “less than significant impact with mitigation.” Where no mitigation measures are necessary, relevant impacts are concluded to be “less than significant impact” or to have “no impact.” As part of the impact analysis, mitigation measures are identified, where feasible, for impacts considered significant or potentially significant consistent with CEQA Guidelines Section 15126.4, which states that an EIR “shall describe feasible measures which could minimize significant adverse impacts.” CEQA requires that mitigation measures have an essential nexus and be roughly proportional to the significant impact identified in the EIR. The project sponsor is required to implement all identified mitigation measures identified in this chapter, and the lead agency (in this case, Contra Costa County) is responsible for overseeing the project sponsor’s implementation of such mitigation measures. Pursuant to CEQA Guidelines Section 15126.4, mitigation measures are not required for environmental impacts that are found not to be significant. Impacts are numbered and shown in bold type. The corresponding mitigation measures, where identified, are numbered and indented, and follow the impact statements. Impacts and mitigation measures are numbered consecutively within each topic and include an abbreviated reference to the impact section (e.g., “LAND” for Land Use and Planning). The following abbreviations are used for individual topics: • Aesthetics, Light, and Glare (AES) • Air Quality (AIR) • Biological Resources (BIO) • Cultural Resources and Tribal Cultural Resources (CUL) • Energy (ENER) • Geology and Soils (GEO) • Greenhouse Gas Emissions (GHG) • Hazards and Hazardous Materials (HAZ) • Hydrology and Water Quality (HYD) • Population and Housing (POP) • Land Use and Planning (LAND) • Noise (NOI) • Public Services (PUB) and Recreation (REC) • Transportation (TRANS) • Utilities and Service Systems (UTIL) • Wildfire (WILD) Contra Costa County–Oak Road Townhouse Condominiums Project Environmental Impact Analysis Draft EIR 3-4 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-00 Env Impact Analysis.docx Cumulative Impacts The discussion of cumulative impacts in this subsection analyzes the cumulative impacts of the proposed project, taken together with other past, present, and reasonably foreseeable future projects producing related impacts. The goal of this analysis is to determine whether the overall long-term impacts of all such projects would be cumulatively significant, and to determine whether the project itself would cause a “cumulatively considerable” incremental contribution to any such cumulatively significant impacts. To determine whether the overall long-term impacts of all such projects would be cumulatively significant, the analysis generally considers the following: • The area in which impacts of the proposed project would be experienced. • The impacts of the proposed project that are expected in the area. • Other past, proposed, and reasonably foreseeable projects that have had or are expected to have impacts in the same area. • The impacts or expected impacts of these other projects. • The overall impact that can be expected if the individual impacts from each project are allowed to accumulate. “Cumulative impacts” refers to two or more individual impacts that, when considered together, are considerable, or that compound or increase other environmental impacts (CEQA Guidelines § 15355). Cumulative impacts can result from individually minor but collectively significant impacts taking place over time (40 Code of Federal Regulations [CFR] 1508.7). If the analysis determines that the potential exists for the project, taken together with other past, present, and reasonably foreseeable future projects, to result in a significant or adverse cumulative impact, the analysis then determines whether the project’s incremental contribution to any significant cumulative impact is itself significant (i.e., “cumulatively considerable”). The cumulative impact analysis for each individual resource topic is presented in each resource section of this chapter immediately after the description of the direct project impacts and identified mitigation measures. Table 3-1 lists the relevant cumulative projects considered for the environmental analysis, and Exhibit 3-1 shows the locations of the cumulative projects (Projects 1 through 24).

This section also evaluates the possible impacts related to aesthetics that could result from implementation of the proposed project. Information included in this section is based upon photo inventory (Exhibit 3.1-1), as well as the Contra Costa County General Plan (General Plan) and the Contra Costa County Ordinance Code (Ordinance Code). During the Notice of Preparation (NOP) comment period, the following comments were received related to the proposed project regarding aesthetics: • Privacy, light and shadow, and view concerns due to the proposed heights of Buildings F, G, and H; stated concerns regarding light pollution. • The proposed project would destroy the artistic style of the project site. • The neighboring residents are asking for larger setback due to privacy, light, views, and shadows concerns. • The proposed project would eliminate views, and inquired about compensation for reduction in property value due to loss of view. • Aesthetics concerns. • Aesthetics concerns because the buildings are too close; concern that the small distance between buildings would impact light. • Proposal to shift the oak grove toward the Oak Treat Court development, creating an open space between it and the proposed project. • Privacy, light, and view concerns due to the height of the proposed buildings. 3.1.2 - Environmental Setting Visual Character Visual character in the California Environmental Quality Act (CEQA) context is an impartial description of the defining physical features, landscape patterns, and distinctive physical qualities within a landscape. Visual character is informed by the composition of land, vegetation, water, and structure and their relationship (or dominance) to one another, and by prominent elements of form, line, color, and texture that combine to define the composition of views. Visual character-defining resources and features within a landscape may derive from notable landforms, vegetation, land uses, building design and façade treatments, transportation facilities, overhead utility structures and lighting, historic structures or districts, or panoramic open space. Contra Costa County Contra Costa County (County) includes a variety of topographical features such as the San Francisco Bay, Delta estuary complex, and is within the Central Coast Range Geomorphic Province of California.

The physical environment of the County ranges from urban to rural. The western and central County areas are characterized by urban and suburban city development. The eastern County area is characterized primarily by agricultural and open space areas. Project Site The project site is in central Contra Costa County, southeast of the intersection of Interstate 680 (I- 680) and Treat Boulevard, and adjacent to the City of Walnut Creek. The project site is relatively flat in elevation and contains several 1- and 2-story buildings, a paved courtyard, a grass field, tennis courts, basketball courts playgrounds, a swimming pool, and associated parking lots and landscaping areas. The site is completely developed and has limited, if any, natural habitat. Numerous mature trees are present on-site. No creeks or wetlands are present on-site. The project site is bound by existing residential areas to the north and south, by Oak Road to the east with a residential area across Oak Road, and by Jones Road to the west. I-680 is located just to the west of Jones Road with a commercial area along its western side. The Contra Costa Canal is approximately 450-600 feet south of the project site (Exhibit 2-3). Scenic Resources Scenic resources typically involve prominent, unique, and identifiable natural features in the environment (e.g., trees, rock outcroppings, islands, ridgelines, channels of water, and aesthetically appealing open space) and cultural features or resources (e.g., regional or architecturally distinctive buildings, or structures that serve as a focal point of interest). Contra Costa County The Open Space Element of the General Plan identifies the main scenic resources within the County as the scenic ridges, hillsides, and rock outcroppings, such as San Pablo Ridge, Pinole Ridge, Sobrante Ridge, Lime Ridge, and Shell Ridge, as well as the San Francisco Bay/Delta estuary system.1 The General Plan also identifies scenic routes as they afford publicly available views. A scenic route is defined in the General Plan as a road, street, or freeway that traverses a scenic corridor of relatively high visual or cultural value. It consists of both the scenic corridor and the public right-of-way.2 1 Contra Costa County Department of Conservation and Development. 2005. Contra Costa County General Plan Land Use Element.

The General Plan identifies the following Scenic Highways and Expressways in the vicinity of the project site:3 • State Route 24 (SR-24) between its intersection with I-680 (approximately 1.9 miles from the project site) and the Alameda County Line to the west. • I-680 between its intersection with SR-24 and the Alameda County Line to the southeast. • SR-242 between its split from I-680 (approximately 2.4 miles north of the project site) and SR- 4 to the north. Project Site There are no scenic resources, as defined by the General Plan, located on the project site. The nearest designated scenic resource to the project site is Diablo Ridge located approximately 2.35 miles to the southeast, approximately 3.95 miles to the east, and approximately 7.45 miles to the northeast. Views Views may be generally described as panoramic vistas from publicly accessible locations of a large geographic area for which the field of vision may be wide and/or may extend into the distance. Examples of distinctive views include urban skylines, valleys, mountain ranges, or large bodies of water. Contra Costa County SR-24 and the portion of I-680 located south of the SR-24 junction, are officially designated State Scenic Highways and are identified as such in Figure 5-4 of the General Plan.4,5 I-580 from the western Contra Costa County Line to the Albany City Limits and SR-4 from Hercules to Bay Point are eligible State Scenic Highways and designated as Scenic Highways in Figure 5-4 of the General Plan. Mount Diablo, rising to an elevation of 3,849 feet, is the most prominent topographical feature in the County. San Pablo Ridge, Pinole Ridge, and Sobrante Ridge are all designated as scenic ridgeways by the General Plan. The San Francisco Bay and Delta estuary complex, including San Pablo Bay and the shores of Suisan Bay, are designated scenic waterways by the General Plan.6 Project Site Photographs depicting existing views are shown in Exhibit 3.1-1. 3 Contra Costa County Department of Conservation and Development. 2005.

Very d istant views of a ridgeline are visible for pedestrians and drivers traveling south on Oak Road, although existing development, such as buildings, roadways, and vegetation largely obstructs this view. Light and Glare In the context of the CEQA Guidelines, light is nighttime illumination that stimulates sight and makes things visible, and glare is difficulty seeing in the presence of bright light such as direct or reflected sunlight. Project Site and Vicinity The project site was formerly a private K-8 school. Several vacant buildings and supporting structures are still present on-site and contribute to existing sources of nighttime security lighting as well as daytime glare. The primary sources of nighttime light in the surrounding area are streetlights on Oak Road and Jones Road and from vehicle headlights traveling along surrounding roadways and I-680, as well as exterior lighting associated with surrounding homes. The streetlights bordering the project site along Oak Road and Jones Road also contribute to nighttime illumination. Surrounding homes and apartment buildings contribute to daytime glare within the project area. 3.1.3 - Regulatory Framework Federal No federal plans, policies, regulations, or laws related to aesthetics are applicable to the proposed project. State California Scenic Highway Program The State Legislature created the California Scenic Highway Program, maintained by the California Department of Transportation (Caltrans), in 1963. The purpose of the State Scenic Highway Program is to protect and enhance the natural scenic beauty of California highways and adjacent corridors, through special conservation treatment. The State laws governing the Scenic Highway Program are found in the Streets and Highways Code, Sections 260 through 263. A highway may be designated scenic depending upon how much of the natural landscape can be seen by travelers, the scenic quality of the landscape, and the extent to which development intrudes upon the traveler’s enjoyment of the view. The State Scenic Highway System includes a list of highways that are either eligible for designation as scenic highways or have been officially designated. The status of a proposed State Scenic Highway changes from eligible to officially designated when the local governing body applies to Caltrans for scenic highway approval, adopts a Corridor Protection Program, and receives notification that the highway has been officially designated a Scenic Highway.

Different lighting standards are set by classifying areas by lighting zone. The classification is based on population figures of the 2000 Census. Areas can be designated as LZ1 (dark), LZ2 (rural), or LZ3 (urban). Lighting requirements for dark and rural areas are stricter in order to protect the areas from new sources of light pollution and light trespass. Local Contra Costa County General Plan Land Use Element The General Plan Land Use Element establishes the following goals and policies related to aesthetics: Goal 3-C To encourage aesthetically and functionally compatible development, which reinforces the physical character and desired images of the county.

Policy 9-25 Maintenance of the scenic waterways of the county shall be ensured through public protection of the marshes and riparian vegetation along the shorelines and delta levees, as otherwise specified in this Plan. Contra Costa County Ordinance Code The County Zoning Map zones the site Multiple-Family Residential (M-17 and M-29) and Single- Family Residential (R-15). The proposed project includes a request to rezone the entire site to P-1. Planned Unit District (P-1) As stated in Chapter 84-66.204, the intent of the P-1 district is to allow “diversification in the relationship of various uses, buildings, structures, lot sizes and open space while insuring (sic) substantial compliance with the general plan and the intent of the county code in requiring adequate standards necessary to satisfy the requirements of the public health, safety and general welfare. These standards shall be observed without unduly inhibiting the advantages of large-scale or special area planning.”7 As summarized in Table 3.1-1, Article 84-66.602 establishes requirements for new and alterations to existing land uses, structures, and site development within the P-1 Zoning District.

Chapter 816-6—Tree Protection and Preservation The Tree Protection and Preservation Ordinance of the County (Chapter 816-6) provides for the preservation of protected trees and requires a permit for activities such as trenching, grading or fill within the drip line of any protected tree, or the removal, destruction, trimming or topping of any protected tree. 8 Heritage trees are defined as a tree 72 inches or more in circumference measured 4.5 feet above natural grade, or any tree or group of trees particularly worthy of protection and specifically designated as such by the Board of Supervisors. No replacement ratio for removed or affected trees is identified in the ordinance. Section 76-4.612—Public Nuisance Lighting The Public Nuisance Lighting Ordinance requires that lighting fixtures be installed, controlled, or directed so that the light will not glare or be blinding to pedestrians or vehicular traffic or on adjoining property.9 3.1.4 - Impacts and Mitigation Measures Significance Criteria According to the CEQA Guidelines’ Appendix G Environmental Checklist, to determine whether impacts to aesthetics are significant environmental effects, the following questions are analyzed and evaluated. Except as provided in Public Resources Code Section 21099, would the project: a) Have a substantial adverse effect on a scenic vista? 8 Contra Costa County.

(Public views are those that are experienced from publicly accessible vantage point). If the project is in an urbanized area, would the project conflict with applicable zoning and other regulations governing scenic quality? d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? Approach to Analysis This analysis provides a discussion of the visual impacts associated with the proposed project and the area surrounding the project site. Several variables affect the degree of visibility, visual contrast, and ultimately project impacts: (1) scale and size of facilities, (2) viewer types and activities, (3) distance and viewing angle, and (4) influences of adjacent scenery or land uses. Viewer response and sensitivity vary depending on viewer attitudes and expectations. As part of this analysis, FCS conducted a field visit of the project site to observe and document the existing visual quality and character of the project site as well as the surrounding areas. Photographs depicting existing views of the project site and vicinity are shown in Exhibit 3.1-1. The General Plan and Ordinance Code were also evaluated to determine applicable policies and design requirements for the project. Light and Glare The analysis of light and glare impacts in this section focuses on the nature and magnitude of changes in light and glare conditions of the project site and surrounding area. If the light and glare conditions of the proposed project and the existing environment are similar, then the visual compatibility would be high. If the light and glare conditions of the proposed project strongly contrast with the existing light and glare or applicable policies and guidelines, then light and glare compatibility would be low and significant impacts may result. Relevant urban design policies and guidelines are used to provide conclusions regarding the significance of project- and cumulative-level light and glare impacts. Specific Thresholds of Significance The County does not have quantitative thresholds for evaluation of aesthetics; however, the following qualitative thresholds are used to evaluate the significance of aesthetics impacts resulting from implementation of the proposed project. • Block existing views from a County-designated scenic roadway toward a County-designated scenic resource (e.g., ridgeline). • Be inconsistent with the character of the plan area or existing development in the surrounding area or would substantially alter existing natural topography. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Aesthetics, Light, and Glare FirstCarbon Solutions 3.1-9 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-01 Aesthetics.docx • Increase existing nighttime light or daytime glare sources in the plan area or vicinity in a manner that would substantially affect nighttime or daytime views. • Reduce sunlight or introduce shadows to public parks and plazas, routinely usable outdoor spaces associated with recreational land uses, pedestrian-oriented commercial spaces such as outdoor eating areas, and existing solar facilities. Impact Evaluation Scenic Vistas Impact AES-1: The proposed project would not have a substantial adverse effect on a scenic resource as identified in the General Plan. There are no scenic resources, as defined by the General Plan, located on the project site. The nearest designated scenic resource to the project site is Diablo Ridge, located approximately 2.35 miles to the southeast, approximately 3.95 miles to the east, and approximately 7.45 miles to the northeast. The nearest scenic roads designated by the General Plan are I-680 and SR-24, which intersect approximately 1.9 miles south of the site. A significant impact would occur if construction of the proposed project would have a substantial adverse effect on a scenic vista,10 as defined and identified in the General Plan. Due to the distance and intervening development, the project site is not visible from either of these scenic routes.11 Construction Construction equipment would be present on the project site intermittently throughout the construction period and could be visible from scenic resources, although since its presence would be temporary, it would not result in a substantial impact to views from any scenic resources or routes. As the project site does not contain any designated scenic resources and is not visible from the nearest designated scenic routes, I-680 and SR-24, removal of the buildings and vegetation would not adversely impact existing views within the project vicinity. Therefore, impacts due to construction would be less than significant. Operation The General Plan’s Open Space Element includes provisions to prohibit development on scenic ridges, hillsides and rock outcroppings where structures would interrupt the skyline, as well as alteration of slopes greater than 26 percent. There are no scenic ridges, hillsides, or rock outcroppings on the project site, nor are any scenic resources visible from the project site. As such, implementation of the project would not result in a substantial adverse effect on a scenic vista. Level of Significance Less than significant impact. 10 A scenic vista is defined as a view point that provides expansive views of a highly valued landscape for the benefit of the general public. 11 Contra Costa County Department of Conservation and Development. 2005.

Construction A significant impact would occur if construction of the proposed project would substantially damage scenic resources as seen from a designated scenic highway. The nearest officially Designated State Scenic Highways are I-680 and SR-24 at their intersection, located approximately 1.9 miles south of the project site; because of the distance to these resources and intervening development, the project site is not visible from either route. In addition, there are no scenic resources, as designated by the General Plan located on the project site. Thus, demolition, grading, and other construction activities would not result in adverse impacts to scenic resources. Therefore, no temporary construction impact related to scenic resources within a State Scenic Highway would occur. Operation A significant impact would occur if operation of the proposed project would substantially damage scenic resources as seen from a designated scenic highway. There are no officially designated State Scenic Highways or County scenic roadways in or adjacent to the project site. The nearest designated scenic routes are I-680 and SR-24 at their intersection, approximately 1.9 miles south of the project site. There are no scenic resources, as defined by the General Plan, located on the project site, of which a view would be available from a scenic highway or roadway. Given the absence of scenic highways proximate to the project site, the lack of designated scenic resources (i.e., ridgelines, hillsides, rock outcroppings) on the project site, and the presence of intervening development between the project site and the nearest scenic highways, the proposed project would not adversely affect views from a State Scenic Highway. Thus, impacts related to scenic resources within a State Scenic Highway would be less than significant. Level of Significance Less than significant impact. Visual Character Impact AES-3: The proposed project is in an urbanized area and would not conflict with applicable zoning and other regulations governing scenic quality. Construction Construction of the proposed project would include building demolition, removal of existing impervious surfaces, and vegetation removal. Construction would also include certain off-site improvements (frontage sidewalk, driveway curb, gutter improvements including retaining existing on-street parking and street tree planting). Thus, the construction could temporarily affect the existing visual character or quality of the project site and area. Considering the residential character of the project site surroundings, construction activities could temporarily affect existing visual character or quality of the project site and area. However, the area surrounding the project site Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Aesthetics, Light, and Glare FirstCarbon Solutions 3.1-11 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-01 Aesthetics.docx has a transit-oriented residential character with multi-family apartments located to the north and to the south. The construction of the project would temporarily affect visual character and quality of the area. However, construction-related impacts related to degradation of existing visual character or quality of the project site and area would be temporary and less than significant. Operation The analysis of operational impacts addresses both consistency with zoning and other regulations governing scenic quality, as well as changes to the existing visual character and quality. The proposed project would change the visual character of the site. The buildings, impervious surfaces, and vegetation would be removed and the site would be developed with 125 townhome condominiums, surface parking, and associated landscaping. The proposed buildings would be 3- stories and approximately 37-43 feet in height. The exterior of the buildings would be composed of standard home-construction materials such as vinyl, metal, glass, and cement, with exterior color schemes of white and gray. Existing residential development in the surrounding area consists newer 3-story apartment buildings, as well as older 2-story apartments, and a few single-family dwellings. The proposed project as designed reflects higher density development in keeping with recent development in proximity to the Bay Area Rapid Transit (BART) Pleasant Hill/Contra Costa Centre station, including the newer Oak Treat Court buildings at the corner of Oak Road and Jones Road, constructed in 2003. The proposed project would be consistent with the character of the surrounding area, as it continues to transition toward higher density multi-family residential uses. The General Plan designates the site as Multiple-Family Residential–High Density (MH). As part of project implementation, the zoning of the project site would be changed to Planned Unit District (P- 1). The P-1 Zoning District is intended to support large-scale integrated development in compliance with the General Plan designations. The proposed project would be consistent with the Design Objectives identified in Section 84-66.1402 of the Ordinance Code related to the P-1 Zoning District. For example, the buildings bulk, height, land coverage, and visual appearance is compatible with existing adjoining development. In addition, the design of the buildings provides for harmonious composition of mass, scale, color, and textures. The proposed project also includes implementation of a landscaping plan, including the planting approximately 250 trees and hundreds of shrubs, vines, and groundcover to replace trees proposed for removal in accordance with the expected permit requirements, expected to be issued as stated in Section 816.6 of the Ordinance Code. The establishment of trees and other plantings would support the transition of the site to reflect the residential character of surrounding properties. Therefore, impacts related to consistency with applicable scenic quality regulations and visual quality and character would be less than significant. Level of Significance Less than significant impact.

Construction Impacts related to degradation of existing visual character or quality of the project site and area are limited to operational impacts. No respective construction impacts would occur. Operation The proposed project would have a significant impact if substantial light or glare would adversely affect nighttime or daytime views, respectively, in the area. The proposed project would result in 125 townhouse condominiums with associated windows, as well as exterior lighting and signage. As noted in the existing setting section, the site is surrounded by residential uses, as well as Oak Road and Jones Road, all of which contribute to the existing daytime glare and nighttime lighting of the area. The proposed project would result in the development of residential uses that would include nighttime security lighting consistent with surrounding uses. Potential sources of light associated with the proposed project would consist of typical sources of lighting associated with a residential development and from vehicles traveling to and from the project site. Exterior lighting would be located around and within the project site. Lampposts would be evenly dispersed within the project site, with safety lighting, as needed throughout the site. In accordance with Section 76-4.612—Public Nuisance Lighting, the proposed project would be required to ensure that lighting fixtures be installed, controlled, or directed so that the light would not glare or be blinding to pedestrians or vehicular traffic or on adjoining property. Therefore, lighting impacts would be less than significant. Glare resulting from the proposed residences’ windows would be minimal and would be partially obscured by landscaping, depending on the time of day and the location of the reflecting light source. Furthermore, residential glass typically has a low reflectivity rate. Glare may also occur from on-site vehicles; however, such glare would be transient, depending upon the time of day and location of the vehicle. Glare resulting from the proposed residences’ windows would be minimal and would be partially obscured by landscaping, depending on the time of day and the location of the reflecting light source. Furthermore, residential glass typically has a low reflectivity rate. In addition, Mitigation Measure (MM) AES-4 requires exterior lighting be directed downward and away from adjacent properties and public/private right-of-way to prevent glare. As such, glare impacts would be less than significant with mitigation. Level of Significance Before Mitigation Potentially significant impact.

Exterior lighting must be directed downward and away from adjacent properties and public/private right-of- way to prevent glare or excessive light spillover. Level of Significance After Mitigation Less than significant impact. 3.1.5 - Cumulative Impacts The geographic scope of the cumulative aesthetics analysis is the visible area surrounding the project site. The analysis also considers the foreseeable development projects listed in Table 3-1 (See Chapter 3, Environmental Setting) in the unincorporated County and surrounding cities, in addition to the proposed project. Visual Character and Views The development projects listed in Table 3-1 are mostly residential and commercial in nature. The proposed project and the projects listed in Table 3-1 propose urban development. None of the Cumulative Projects would be located within the same visible area as the proposed project. The proposed project and Cumulative Projects 1 and 2 would be subject to the same County codes and guidelines related to building heights, setbacks, undergrounding of utilities, landscaping, signage, and permitted land uses. Cumulative Projects 3–13 would be subject to the codes and guidelines associated with the City of Walnut Creek related to building heights, setbacks, undergrounding of utilities, landscaping, signage, and permitted land uses. Cumulative Projects 14– 24 would be subject to the codes and guidelines associated with the City of Pleasant Hill related to building heights, setbacks, undergrounding of utilities, landscaping, signage, and permitted land uses. As such, the proposed project, in conjunction with other planned and approved projects, would result in a less than significant cumulative impact with respect to visual character and views. Light and Glare The development projects listed in Table 3-1 are mostly residential and commercial in nature. The project and the projects listed in Table 3-1 propose urban development. None of the Cumulative Projects would be located within the same visible area. The nearest Cumulative Projects is Project 9, located approximately 0.4 mile and several blocks away from the proposed project, and therefore would not contribute to light and glare in the vicinity of the proposed project. As such, the proposed project, in conjunction with other planned and approved projects, would result in a less than significant cumulative impact with respect to light and glare.

The Air Basin is approximately 5,600 square miles in area and consists of nine counties that surround the San Francisco Bay, including all of Alameda, Contra Costa, Marin, San Francisco, San Mateo, Santa Clara, and Napa Counties; the southwestern portion of Solano County; and the southern portion of Sonoma County. The San Francisco Bay Area (Bay Area) has a Mediterranean climate characterized by mild, dry summers and mild, moderately wet winters; moderate daytime onshore breezes, and moderate humidity. A semi-permanent, high-pressure area centered over the northeastern Pacific Ocean dominates the summer climate of the West Coast. Because this high-pressure cell is persistent, storms rarely affect the California coast during the summer. Thus, the conditions that persist along the coast of California during summer are a northwest airflow and negligible precipitation. A thermal low-pressure area from the Sonoran-Mojave Desert also causes air to flow onshore over the Bay Area much of the summer. Contra Costa County—Oak Road Townhouse Condominiums Project Air Quality Draft EIR 3.2-2 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx The steady northwesterly flow around the eastern edge of the Pacific High (a high-pressure cell) exerts stress on the ocean surface along the West Coast. This induces upwelling of cold water from below the surface. Upwelling produces a band of cold water off San Francisco that is approximately 80 miles wide. During July, the surface waters off San Francisco are 3°F (degrees Fahrenheit) cooler than those off Vancouver, British Columbia, more than 900 miles to the north. Air approaching the California coast, already cool and moisture-laden from its long trajectory over the Pacific, is further cooled as it flows across this cold bank of water near the coast, thus accentuating the temperature contrast across the coastline. This cooling is often sufficient to produce condensation–a high incidence of fog and stratus clouds along the Northern California coast in summer. In summer, the northwest winds to the west of the Pacific coastline are drawn into the interior through the gap in the western Coast Ranges, known as the Golden Gate, and over the lower portions of the San Francisco Peninsula. Immediately to the south of Mount Tamalpais, the northwesterly winds accelerate considerably and come more nearly from the west as they stream through the Golden Gate. This channeling of the flow through the Golden Gate 1 produces a jet that sweeps eastward but widens downstream, producing southwest winds at Berkeley and northwest winds at San José; a branch also curves eastward through the Carquinez Straits and into the Central Valley. Wind speeds may be locally strong in regions where air is channeled through a narrow opening such as the Golden Gate, the Carquinez Strait, or San Bruno Gap. For example, the average wind speed at San Francisco International Airport from 3:00 a.m. to 4:00 p.m. in July is about 20 miles per hour (mph), compared with only about 8 mph at San José and less than 7 mph at the Farallon Islands. The sea breeze between the coast and the Central Valley 2 commences near the surface along the coast in late morning or early afternoon; it may first be observed only through the Golden Gate. Later in the day, the layer deepens and intensifies while spreading inland. As the breeze intensifies and deepens, it flows over the lower hills farther south along the peninsula. This process frequently can be observed as a bank of stratus clouds “rolling over” the coastal hills on the west side of the Bay. The depth of the sea breeze depends in large part upon the height and strength of the inversion. The generally low elevation of this stable layer of air prevents marine air from flowing over the coastal hills. It is unusual for the summer sea breeze to flow over terrain exceeding 2,000 feet in elevation. In winter, the Air Basin experiences periods of storminess, moderate-to-strong winds, and periods of stagnation with very light winds. Winter stagnation episodes are characterized by outflow from the Central Valley, nighttime drainage flows in coastal valleys, weak onshore flows in the afternoon, and otherwise light and variable winds. A primary factor in air quality is the mixing depth (the vertical air column available for dilution of contaminant sources). Generally, the temperature of air decreases with height, creating a gradient from warmer air near the ground to cooler air at elevation caused by the sun converting large amounts of energy to sensible heat at the ground, which in turn warms the air at the surface. The warm air rises in the atmosphere, where it expands and cools. Sometimes, however, the temperature of air actually increases with height. This condition is known as temperature inversion 1 A strait on the West Coast of North America that connects the San Francisco Bay to the Pacific Ocean. 2 A flat valley that dominates the geographical center of California stretching 450 miles from north-northwest to south-southeast, inland from and parallel to the Pacific Ocean coast. It is bound by the Sierra Nevada to the east and the Coast Range to the west.

Over the Air Basin, the frequent occurrence of temperature inversions limits mixing depth and, consequently, limits the availability of air for dilution. Air Pollutant Types, Sources, and Effects Criteria Air Pollutants Concentrations of criteria air pollutants are used as indicators of air quality conditions. Air pollutants are termed criteria air pollutants if they are regulated by developing specific public health- and welfare- based criteria as the basis for setting permissible levels. According to the United States Environmental Protection Agency (EPA), criteria air pollutants are ozone, particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), lead, and sulfur dioxide (SO2). Table 3.2-1 provides a summary of the types, sources, and effects of criteria air pollutants of national and California concern. Table 3.2-1: Description of Criteria Pollutants of National and California Concern Criteria Pollutant Physical Description and Properties Sources Most Relevant Effects from Pollutant Exposure Ozone Ozone is a photochemical pollutant as it is not emitted directly into the atmosphere, but is formed by a complex series of chemical reactions between reactive organic gases (ROG), nitrous oxides (NOX), and sunlight. Ozone is a regional pollutant that is generated over a large area and is transported and spread by the wind. Ozone is a secondary pollutant; thus, it is not emitted directly into the lower level of the atmosphere. The primary sources of ozone precursors (ROG and NOX) are mobile sources (on-road and off-road vehicle exhaust). Irritate respiratory system; reduce lung function; breathing pattern changes; reduction of breathing capacity; inflame and damage cells that line the lungs; make lungs more susceptible to infection; aggravate asthma; aggravate other chronic lung diseases; cause permanent lung damage; some immunological changes; increased mortality risk; vegetation and property damage. Particulate matter (PM10) Suspended particulate matter is a mixture of small particles that consist of dry solid fragments, droplets of water, or solid cores with liquid coatings. The particles vary in shape, size, and composition. PM10 refers to particulate matter that is between 2.5 and 10 microns in diameter, (one micron is one-millionth of a meter). PM2.5 refers to particulate matter that is 2.5 microns or less in diameter, about one-thirtieth the size of the average human hair. Stationary sources include fuel or wood combustion for electrical utilities, residential space heating, and industrial processes; construction and demolition; metals, minerals, and petrochemicals; wood products processing; mills and elevators used in agriculture; erosion from tilled lands; waste disposal, and recycling. Mobile or transportation- related sources are from vehicle exhaust and road dust. Secondary particles form from reactions in the atmosphere. • Short-term exposure (hours/days): irritation of the eyes, nose, throat; coughing; phlegm; chest tightness; shortness of breath; aggravate existing lung disease, causing asthma attacks and acute bronchitis; those with heart disease can suffer heart attacks and arrhythmias. • Long-term exposure: reduced lung function; chronic bronchitis; changes in lung morphology; death. Particulate matter (PM2.5) Contra Costa County—Oak Road Townhouse Condominiums Project Air Quality Draft EIR 3.2-4 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx Criteria Pollutant Physical Description and Properties Sources Most Relevant Effects from Pollutant Exposure Nitrogen dioxide (NO2) During combustion of fossil fuels, oxygen reacts with nitrogen to produce nitrogen oxides—NOX (NO, NO2, NO3, N2O, N2O3, N2O4, and N2O5). NOX is a precursor to ozone, PM10, and PM2.5 formation. NOX can react with compounds to form nitric acid and related small particles and result in particulate matter (PM) related health effects. NOX is produced in motor vehicle internal combustion engines and fossil-fuel-fired electric utility and industrial boilers. Nitrogen dioxide forms quickly from NOX emissions. NO2 concentrations near major roads can be 30 to 100 percent higher than those at monitoring stations. Potential to aggravate chronic respiratory disease and respiratory symptoms in sensitive groups; risk to public health implied by pulmonary and extra-pulmonary biochemical and cellular changes and pulmonary structural changes; contributions to atmospheric discoloration; increased visits to hospital for respiratory illnesses. Carbon monoxide (CO) CO is a colorless, odorless, toxic gas. CO is somewhat soluble in water; therefore, rainfall and fog can suppress CO conditions. CO enters the body through the lungs, dissolves in the blood, replaces oxygen as an attachment to hemoglobin, and reduces available oxygen in the blood. CO is produced by incomplete combustion of carbon-containing fuels (e.g., gasoline, diesel fuel, and biomass). Sources include motor vehicle exhaust, industrial processes (metals processing and chemical manufacturing), residential woodburning, and natural sources. Ranges depending on exposure: slight headaches; nausea; aggravation of angina pectoris (chest pain) and other aspects of coronary heart disease; decreased exercise tolerance in persons with peripheral vascular disease and lung disease; impairment of central nervous system functions; possible increased risk to fetuses; death. Sulfur dioxide (SO2) Sulfur dioxide is a colorless, pungent gas. At levels greater than 0.5 parts per million (ppm), the gas has a strong odor, similar to rotten eggs. Sulfur oxides (SOX) include sulfur dioxide and sulfur trioxide. Sulfuric acid is formed from sulfur dioxide, which can lead to acid deposition and can harm natural resources and materials. Although sulfur dioxide concentrations have been reduced to levels well below State and federal standards, further reductions are desirable because sulfur dioxide is a precursor to sulfate and PM10. Human caused sources include fossil-fuel combustion, mineral ore processing, and chemical manufacturing. Volcanic emissions are a natural source of sulfur dioxide. The gas can also be produced in the air by dimethyl sulfide and hydrogen sulfide. Sulfur dioxide is removed from the air by dissolution in water, chemical reactions, and transfer to soils and ice caps. The sulfur dioxide levels in the State are well below the maximum standards. Bronchoconstriction accompanied by symptoms which may include wheezing, shortness of breath and chest tightness, during exercise or physical activity in persons with asthma. Some population- based studies indicate that the mortality and morbidity effects associated with fine particles show a similar association with ambient sulfur dioxide levels. It is not clear whether the two pollutants act synergistically, or one pollutant alone is the predominant factor.

Leaded gasoline was used in motor vehicles until around 1970. Lead concentrations have not exceeded State or federal standards at any monitoring station since 1982. Lead ore crushing, lead ore smelting, and battery manufacturing are currently the largest sources of lead in the atmosphere in the United States. Other sources include dust from soils contaminated with lead-based paint, solid waste disposal, and crustal physical weathering. Lead accumulates in bones, soft tissue, and blood and can affect the kidneys, liver, and nervous system. It can cause impairment of blood formation and nerve conduction, behavior disorders, mental retardation, neurological impairment, learning deficiencies, and low IQs.

TACs are defined as air pollutants that may cause or contribute to an increase in mortality or serious illness or that may pose a hazard to human health. TACs are usually present in minute quantities in the ambient air; however, their high toxicity or health risk may pose a threat to public health even at very low concentrations. TACs can cause long-term health effects (such as cancer, birth defects, neurological damage, asthma, bronchitis, or genetic damage) or short-term acute affects (such as eye watering, respiratory irritation, runny nose, throat pain, or headaches). For TACs that may cause cancer, all concentrations present some risk. In other words, there is no threshold level below which some adverse health impacts are not expected to occur. This contrasts with the criteria pollutants such as nitrogen dioxide and carbon dioxide for which acceptable levels of exposure can be determined and for which the State and federal governments have set ambient air quality standards. TACs are separated into carcinogens and noncarcinogens based on the nature of the physiological effects associated with exposure to a particular TAC. Carcinogens are assumed to have no safe threshold below which health impacts would not occur. Cancer risk is typically expressed as excess cancer cases per million exposed individuals, typically over a lifetime exposure or other prolonged duration. For non-carcinogenic substances, there is generally an assumed safe level of exposure below which no negative health impact is believed to occur. These levels may vary depending on the specific pollutant. Acute and chronic exposure to noncarcinogens is expressed as a hazard index (HI), which is the ratio of expected exposure levels to an acceptable reference exposure levels. To date, the California Air Resources Board (ARB) has designated nearly 200 compounds as TACs. The ARB has implemented control measures for a number of compounds that pose high risks and show potential for effective control. The majority of the estimated health risk from TACs can be attributed to a relatively few compounds, the most important being diesel particulate matter (DPM) from diesel-fueled engines. Common TACs of national and California concern include DPM, reactive organic gases (ROG), benzene, asbestos, hydrogen sulfide, sulfates, visibility-reducing particulates, vinyl chloride, and lead. Table 3.2-2 provides a summary of the types, sources, and effects of TACs of national and California concern. Table 3.2-2: Description of Toxic Air Contaminants of National and California Concern Toxic Air Contaminant Physical Description and Properties Sources Most Relevant Effects from Pollutant Exposure Diesel Particulate Matter (DPM) DPM is a source of PM2.5— diesel particles are typically 2.5 microns and smaller. Diesel exhaust is a complex mixture of thousands of particles and gases that is produced when an engine burns diesel fuel. Organic compounds account for 80 percent of the total PM mass, which consists of compounds Diesel exhaust is a major source of ambient PM pollution in urban environments. Typically, the main source of DPM is from combustion of diesel fuel in diesel-powered engines. Such engines are in on-road vehicles such as diesel trucks, off-road construction vehicles, diesel electrical Some short-term (acute) effects of DPM exposure include eye, nose, throat, and lung irritation, coughs, headaches, light- headedness, and nausea. Studies have linked elevated particle levels in the air to increased hospital admissions, emergency room visits, asthma attacks, and premature deaths Contra Costa County—Oak Road Townhouse Condominiums Project Draft EIR Air Quality FirstCarbon Solutions 3.2-7 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx Toxic Air Contaminant Physical Description and Properties Sources Most Relevant Effects from Pollutant Exposure such as hydrocarbons and their derivatives, and polycyclic aromatic hydrocarbons and their derivatives. Fifteen polycyclic aromatic hydrocarbons are confirmed carcinogens, a number of which are found in diesel exhaust. generators, and various pieces of stationary construction equipment. among those suffering from respiratory problems. Human studies on the carcinogenicity of DPM demonstrate an increased risk of lung cancer, although the increased risk cannot be clearly attributed to diesel exhaust exposure. ROGs ROGs, or volatile organic compounds (VOC), are defined as any compound of carbon—excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate—that participates in atmospheric photochemical reactions. Although there are slight differences in the definition of ROGs and VOCs, the two terms are often used interchangeably. Indoor sources of ROGs include paints, solvents, aerosol sprays, cleansers, tobacco smoke, etc. Outdoor sources of ROGs are from combustion and fuel evaporation. A reduction in ROG emissions reduces certain chemical reactions that contribute to the formulation of ozone. ROGs are transformed into organic aerosols in the atmosphere, which contribute to higher PM10 and lower visibility. Although health-based standards have not been established for ROGs, health effects can occur from exposures to high concentrations because of interference with oxygen uptake. In general, concentrations of ROGs are suspected to cause eye, nose, and throat irritation; headaches; loss of coordination; nausea; and damage to the liver, the kidneys, and the central nervous system. Many ROGs have been classified as TACs . Benzene Benzene is a ROG. It is a clear or colorless light-yellow, volatile, highly flammable liquid with a gasoline-like odor. The EPA has classified benzene as a “Group A” carcinogen. Benzene is emitted into the air from fuel evaporation, motor vehicle exhaust, tobacco smoke, and from burning oil and coal. Benzene is used as a solvent for paints, inks, oils, waxes, plastic, and rubber. Benzene occurs naturally in gasoline at 1 to 2 percent by volume. The primary route of human exposure is through inhalation. Short-term (acute) exposure of high doses from inhalation of benzene may cause dizziness, drowsiness, headaches, eye irritation, skin irritation, and respiratory tract irritation, and at higher levels, loss of consciousness can occur. Long-term (chronic) occupational exposure of high doses has caused blood disorders, leukemia, and lymphatic cancer. Asbestos Asbestos is the name given to a number of naturally occurring fibrous silicate minerals that have been mined for their useful properties such as thermal insulation, chemical and thermal stability, and high tensile strength. The three Chrysotile, also known as white asbestos, is the most common type of asbestos found in buildings. Chrysotile makes up approximately 90 to 95 percent of all asbestos contained in buildings in the United States. Exposure to asbestos is a health threat; exposure to asbestos fibers may result in health issues such as lung cancer, mesothelioma (a rare cancer of the thin membranes lining the lungs, chest, and abdominal cavity), and asbestosis (a Contra Costa County—Oak Road Townhouse Condominiums Project Air Quality Draft EIR 3.2-8 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx Toxic Air Contaminant Physical Description and Properties Sources Most Relevant Effects from Pollutant Exposure most common types of asbestos are chrysotile, amosite, and crocidolite. non-cancerous lung disease that causes scarring of the lungs). Exposure to asbestos can occur during demolition or remodeling of buildings that were constructed prior to the 1977 ban on asbestos for use in buildings. Exposure to naturally occurring asbestos can occur during soil-disturbing activities in areas with deposits present. Hydrogen Sulfide Hydrogen sulfide (H2S) is a flammable, colorless, poisonous gas that smells like rotten eggs. Manure, storage tanks, ponds, anaerobic lagoons, and land application sites are the primary sources of hydrogen sulfide. Anthropogenic sources include the combustion of sulfur containing fuels (oil and coal). High levels of hydrogen sulfide can cause immediate respiratory arrest. It can irritate the eyes and respiratory tract and cause headache, nausea, vomiting, and cough. Long exposure can cause pulmonary edema. Sulfates Sulfates occur in combination with metal and/or hydrogen ions. Many sulfates are soluble in water. Sulfates are particulates formed through the photochemical oxidation of sulfur dioxide. In California, the main source of sulfur compounds is combustion of gasoline and diesel fuel. (a) Decrease in ventilatory function. (b) Aggravation of asthmatic symptoms.

In 1990, the California Air Resources Board (ARB) identified vinyl chloride as a toxic air contaminant and estimated a cancer unit risk factor. Most vinyl chloride is used to make polyvinyl chloride plastic and vinyl products, including pipes, wire and cable coatings, and packaging materials. It can be formed when plastics containing these substances are left to decompose in solid waste landfills. Vinyl chloride has been detected near landfills, sewage plants, and hazardous waste sites. Short-term exposure to high levels of vinyl chloride in the air causes central nervous system effects, such as dizziness, drowsiness, and headaches. Epidemiological studies of occupationally exposed workers have linked vinyl chloride exposure to development of a rare cancer, liver angiosarcoma, and have suggested a relationship between exposure and lung and brain cancers.

Community Risk To reduce exposure to TACs, the ARB developed and approved the Air Quality and Land Use Handbook: A Community Health Perspective (2005) to provide guidance regarding the siting of sensitive land uses in the vicinity of freeways, distribution centers, rail yards, ports, refineries, chrome-plating facilities, dry cleaners, and gasoline-dispensing facilities. This guidance document was developed to assess compatibility and associated health risks when siting sensitive receptors near existing pollution sources. The ARB’s recommendations were based on a compilation of recent studies that evaluated data on the adverse health effects from proximity to air pollution sources. The key observation in these studies is that proximity substantially increases exposure and the potential for adverse health effects. Three carcinogenic TACs constitute the majority of the known health risks from motor vehicle traffic—DPM from trucks and benzene and 1,3-butadiene from passenger vehicles. ARB recommendations are based on data that show that localized air pollution exposures can be reduced by as much as 80 percent by following ARB minimum distance separations. Air Quality Air quality is a function of both the rate and location of pollutant emissions under the influence of meteorological conditions and topographic features. Atmospheric conditions such as wind speed, wind direction, and air temperature inversions interact with the physical features of the landscape to determine the movement and dispersal of air pollutant emissions and, consequently, their effect on air quality. Regional Air Quality The Bay Area Air Quality Management District (BAAQMD) is the regional agency with jurisdiction for regulating air quality within the nine county Air Basin, which includes Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, and Santa Clara counties, the western portion of Solano County, and the southern portion of Sonoma County. Air Pollutant Standards and Attainment Designations Air pollutant standards have been identified by the EPA and the ARB for the following six criteria air pollutants that affect ambient air quality: ozone, NO2, CO, SO2, lead, and particulate matter (PM), which is subdivided into two classes based on particle size: PM with aerodynamic diameters equal to Contra Costa County—Oak Road Townhouse Condominiums Project Draft EIR Air Quality FirstCarbon Solutions 3.2-11 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx or less than 10 microns (PM10), and PM with aerodynamic diameters equal to or less than 2.5 microns (PM2.5). These air pollutants are called “criteria air pollutants,” because they are regulated by developing specific public health- and welfare-based criteria as the basis for setting permissible levels. California has also established standards for TACs such as visibility-reducing particles, sulfates, hydrogen sulfide, and vinyl chloride. Tab le 3.2-3 presents the National Ambient Air Quality Standards (NAAQS) and California Ambient Air Quality Standards (CAAQS) for these aforementioned air pollutants. Note that there are no State or federal ambient air quality standards for ROGs, benzene, or DPM.

All standards listed are primary standards except for 3-Hour SO2, which is a secondary standard. A secondary standard is the level of air quality necessary to protect the public welfare from any known or anticipated adverse effects of a pollutant. b To attain the 1-hour nitrogen dioxide national standard, the 3-year average of the annual 98th percentile of the 1-hour daily maximum concentrations at each site must not exceed 100 parts per billion (0.100 ppm). c On June 2, 2010, a new 1-hour SO2 standard was established, and the existing 24-hour and annual primary standards were revoked. To attain the 1-hour national standard, the 3-year average of the annual 99th percentile of the 1-hour daily maximum concentrations at each site must not exceed 75 part per billion (ppb). The 1971 SO2 national standards (24-hour and annual) remain in effect until one year after an area is designated for the 2010 standard, except that in areas designated non-attainment for the 1971 standards, the 1971 standards remain in effect until implementation plans to attain or maintain the 2010 standards are approved. d Visibility-reducing particles: In 1989, the ARB converted both the general Statewide 10-mile visibility standard and the Lake Tahoe 30-mile visibility standard to instrumental equivalents, which are “extinction of 0.23 per kilometer” and “extinction of 0.07 per kilometer” for the Statewide and Lake Tahoe Air Basin standards, respectively. e The ARB has identified lead and vinyl chloride as “toxic air contaminants” with no threshold level of exposure for adverse health effects determined. These actions allow for the implementation of control measures at levels below the ambient concentrations specified for these pollutants. f The EPA Administrator approved a revised 8-hour ozone standard of 0.07 ppb on October 1, 2015. The new standard went into effect 60 days after publication of the Final Rule in the Federal Register. The Final Rule was published in the Federal Register on October 26, 2015, and became effective on December 28, 2015. Source: California Air Resources Board (ARB). 2016. Ambient Air Quality Standards.

Air quality monitoring stations operated by the ARB and BAAQMD measure ambient air pollutant concentrations in the Air Basin. In general, the Air Basin experiences low concentrations of most pollutants compared to federal or State standards. Both the EPA and ARB use ambient air quality monitoring data to designate areas according to their attainment status for criteria air pollutants. The purpose of these designations is to identify the areas with air quality problems and initiate planning efforts for improvement. The three basic designation categories are non-attainment, attainment, and unclassified. “Attainment” status refers to those regions that are meeting federal and/or State standards for a specified criteria pollutant. “Non- attainment ” refers to regions that do not meet federal and/or State standards for a specified criteria pollutant. “Unclassified” refers to regions where there is not enough data to determine the region’s attainment status for a specified criteria air pollutant. Each standard has a different definition, or “form” of what constitutes attainment, based on specific air quality statistics. For example, the federal 8-hour CO standard is not to be exceeded more than once per year; therefore, an area is in attainment of the CO standard if no more than one 8-hour ambient air monitoring values exceeds the threshold per year. In contrast, the federal annual PM2.5 standard is met if the three-year average of the annual average PM2.5 concentration is less than or equal to the standard. Table 3.2-4 shows the current attainment designations for the Air Basin. The Air Basin is designated as non-attainment for the State ozone, PM10, and PM2.5, standards, and the national ozone and PM2.5 standards.

Air Quality Index The health impacts of the various air pollutants of concern can be presented in a number of ways. The clearest comparison is to the State and federal ozone standards. If concentrations are below the standard, it is safe to say that no health impact would occur to anyone. When concentrations exceed the standard, impacts will vary based on the amount by which the standard is exceeded. The EPA developed the Air Quality Index (AQI) as an easy-to-understand measure of health impacts compared with concentrations in the air. Table 3.2-5 provides a general description of the health impacts of ozone at different concentrations.

Local Air Quality Air quality is a function of both the rate and location of pollutant emissions under the influence of meteorological conditions and topographic features. Atmospheric conditions such as wind speed, wind direction, and air temperature inversions interact with the physical features of the landscape to determine the movement and dispersal of air pollutant emissions and, consequently, their effect on air quality. The local air quality can be evaluated by reviewing relevant air pollution concentrations near the project area. The air quality monitoring station closest to the project site is the Concord-2975 Treat Boulevard Air Monitoring site, which is located approximately 2 miles northeast of the project site.

Air Pollution Sensitive Receptors Air pollution does not affect every individual in the population in the same way, and some groups are more sensitive to adverse health effects than others are. Land uses such as residences, schools, day care centers, hospitals, nursing and convalescent homes, and parks are considered the most sensitive to poor air quality, because the population groups associated with these uses have increased susceptibility to respiratory distress or, as in the case of residential receptors, their exposure time is greater than that for other land uses. Therefore, these groups are referred to as sensitive receptors. Exposure assessment guidance typically assumes that residences would receive exposure to air pollution 24 hours per day, 350 days per year, for 70 years. The BAAQMD defines sensitive receptors as children, adults, and seniors occupying or residing in residential dwellings, schools, day care centers, hospitals, and senior-care facilities. Project Vicinity The project site is surrounded by existing residences to the south, east, and north of the project site. The closest off-site air pollution sensitive receptors in the vicinity of the project site include multi- family apartments north and south of the project site as well as single-family residences east of the project site across Oak Road. It is important to note that these receptors do not necessarily represent the maximally impacted sensitive receptor as the combination of prevailing meteorological conditions, emission source location, and receptor location all influence what receptor is most impacted by air pollutants. Project Site The 5.94-acre project site consists of eight existing legal parcels; refer to Exhibit 2-5 in Section 2, Project Description. The project site is relatively flat (approximately 90 and 95 feet above mean sea level). The regional topographic gradient slopes gently to the northeast. The site is developed with structures associated with the former Palmer School for Boys and Girls, a private K-8 school that operated at the project site from 1939 until its closure due to COVID-19 in June 2020. The former school consists of 14 vacant buildings and associated structures, including classrooms, an auditorium, a front office, a paved courtyard, a grass field, tennis courts, basketball courts playgrounds, a swimming pool, parking lots and planters. Multiple storage sheds are present on the school site. The classrooms, located in the southern portion of the school site, are generally empty Contra Costa County—Oak Road Townhouse Condominiums Project Draft EIR Air Quality FirstCarbon Solutions 3.2-17 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx or used as storage rooms for classroom materials. Situated outside of the classrooms are rows of lockers, bathrooms, and a janitorial supply closet with a boiler. A landscaping area behind the classrooms along the southern boundary of the project site includes planter boxes, storm drain lines, and power boxes, and a partially uncovered pipe which appears to be related to storm drainage. In the southeast corner of the project site is a 2-story auditorium formerly used as a storage area containing a kitchen, stage, water heater, and empty storage rooms on the second floor. Structures in the northern portion of the project site are associated with previous residential uses that were converted into storage areas for the school; these structures are all now vacant. East of these buildings is an unpaved lot. Existing Air Pollutant Emissions Project Site Vicinity The primary sources of air pollutants (both criteria air pollutant and TACs) in the project site vicinity include the various surrounding residential properties, building-related energy use, and motor- related vehicle trips associated with the local business use, particularly on the major nearby roadways, Oak Road, Treat Boulevard, and Highway 680. Other sources of emissions include space and water heating, landscape maintenance, and any surrounding commercial uses which have the potential to contain BAAQMD-permitted stationary source equipment or store, produce, decommission, or otherwise handle hazardous materials. Project Site The project site consists of vacant buildings and does not produce any air pollutants. The project site is located in an area identified by the BAAQMD Community Air Risk Evaluation (CARE) Program as containing a high-risk for concentrated air pollutants and toxins.3 The CARE Program was established by California State Assembly Bill (AB) 617 (C. Garcia. Chapter 136, Statutes of 2017) which requires the ARB, Air Quality Management Districts (AQMDs), and communities to establish and enforce community-scaled emissions and air pollution monitoring programs in high- risk areas for non-vehicular air pollutants and TACs to meet updated air quality standards. The main focus of the CARE Program is to reduce additional air pollutant exposure in communities that are already severely impacted by air pollution. The project site and East Walnut Creek area are subject to AB 617 and are closely monitored by regional community air pollution monitoring programs. 3.2.3 - Regulatory Framework Federal Clean Air Act Congress established much of the basic structure of the Clean Air Act (CAA) in 1970 and made major revisions in 1977 and 1990. The CAA addresses six common air pollutants (also known as criteria pollutants). These are PM, ground-level ozone, CO, sulfur oxides, nitrogen oxides, and lead.

The set of limits based on human health are called primary standards. Another set of limits intended to prevent environmental and property damage are called secondary standards.4 The federal standards are called NAAQS. The air quality standards provide benchmarks for determining whether air quality is healthy at specific locations and whether development activities will cause or contribute to a violation of the standards. The criteria pollutants are: • Ozone • Particulate matter (PM10 and PM2.5) • Nitrogen dioxide (NO2) • Carbon monoxide (CO) • Lead • Sulfur dioxide The federal standards were set to protect public health, including that of sensitive individuals; thus, the EPA is tasked with updating the standards as more medical research is available regarding the health effects of the criteria pollutants. Primary federal standards are the levels of air quality necessary, with an adequate margin of safety, to protect the public health. The CAA also requires each state to prepare an Air Quality Plan (AQP) referred to as a State Implementation Plan (SIP). The federal CAA Amendments of 1990 added requirements for states with non-attainment areas to revise their SIPs to incorporate additional control measures to reduce air pollution. The SIP is periodically modified to reflect the latest emissions inventories, planning documents, and rules and regulations of the air basins, as reported by their jurisdictional agencies. EPA Emission Standards for New Off-Road Equipment Before 1994, there were no standards to limit the amount of emissions from off-road equipment. In 1994, the EPA established emission standards for hydrocarbons, NOX, CO, and PM to regulate new pieces of off-road equipment. These emission standards came to be known as Tier 1. Since that time, the EPA and ARB have adopted increasingly more stringent Tier 2, Tier 3, and Tier 4 (interim and final) standards. Each adopted emission standard was phased in over time. New engines built in and after 2015 across all horsepower sizes must meet Tier 4 final emission standards. In other words, new manufactured engines cannot exceed the emissions established for Tier 4 final emissions standards. State California Air Quality Control Plan (State Implementation Plan) An SIP is a document prepared by each State describing existing air quality conditions and measures intended to attain and maintain federal standards. The SIP for the State of California is administered by the ARB, which has overall responsibility for Statewide air quality maintenance and air pollution prevention. California’s SIP incorporates individual federal attainment plans for regional air districts—an air district prepares their federal attainment plan and sends it to the ARB for approval and incorporation into the California SIP. 4 United States Environmental Protection Agency (EPA). 2017.

Areas designated non-attainment must develop AQPs and regulations to achieve standards by specified dates, depending on the severity of the exceedances. For much of the country, implementation of federal motor vehicle standards and compliance with federal permitting requirements for industrial sources are adequate to attain air quality standards on schedule. For many areas of California, however, additional State and local regulation is required to achieve the standards. California Clean Air Act The California Legislature enacted the California Clean Air Act (CCAA) in 1988 to address air quality issues of concern not adequately addressed by the federal CAA at the time. California’s air quality problems were and continue to be some of the most severe in the nation, and required additional actions beyond the federal mandates. The ARB administers the CAAQS for the 10 air pollutants designated in the CCAA. The 10 State air pollutants are the six federal standards listed above as well as visibility-reducing particulates, hydrogen sulfide, sulfates, and vinyl chloride. The EPA authorized California to adopt its own regulations for motor vehicles and other sources that are more stringent than similar federal regulations implementing the CAA. Generally, the planning requirements of the CCAA are more stringent than the federal CAA; therefore, consistency with the CAA will also demonstrate consistency with the CCAA. Other ARB responsibilities include but are not limited to overseeing local air district compliance with California and federal laws; approving local AQPs; submitting SIPs to the EPA; monitoring air quality; determining and updating area designations and maps; conducting basic research aimed at providing a better understanding between emissions and public well-being, and setting emissions standards for new mobile sources, consumer products, small utility engines, off-road vehicles, and fuels. California Health and Safety Code Section 39655 and California Code of Regulations Title 17 Section 93000 (Substances Identified as Toxic Air Contaminants) The ARB identifies substances as TACs as defined in Health and Safety Code Section 39655 and listed in Title 17, Section 93000 of the California Code of Regulations, “Substances Identified As Toxic Air Contaminants.” A TAC is defined as an air pollutant that may cause or contribute to an increase in mortality or serious illness, or that may pose a hazard to human health. TACs are usually present in minute quantities in the ambient air; however, their high toxicity or health risk may pose a threat to public health even at low concentrations. In general, for those TACs that may cause cancer, regulatory agencies set thresholds below which adverse health impacts are not expected to occur. This contrasts with the criteria pollutants for which acceptable levels of exposure can be determined and for which the State and federal governments have set ambient air quality standards. According to the California Almanac of Emissions and Air Quality, the majority of the estimated health risk from TACs for the State of California can be attributed to relatively few compounds, the most important of which is DPM from diesel-fueled engines.

These first LEV standards ran from 1994 through 2003. LEV II regulations, running from 2004 through 2010, represent continuing progress in emission reductions. As the State’s passenger vehicle fleet continues to grow and more sport utility vehicles and pickup trucks are used as passenger cars rather than work vehicles, the more stringent LEV II standards were adopted to provide reductions necessary for California to meet federally mandated clean air goals outlined in the 1994 SIP. In 2012, the ARB adopted the LEV III amendments to California’s LEV regulations. These amendments, also known as the Advanced Clean Car Program, include more stringent emission standards for model years 2017 through 2025 for both criteria pollutants and greenhouse gas (GHG) emissions for new passenger vehicles.5 California On-Road Heavy-Duty Vehicle Program The ARB has adopted standards for emissions from various types of new on-road heavy-duty vehicles. Section 1956.8, Title 13, California Code of Regulations contains California’s emission standards for on-road heavy-duty engines and vehicles, and test procedures. The ARB has also adopted programs to reduce emissions from in-use heavy-duty vehicles including the Heavy-Duty Diesel Vehicle Idling Reduction Program, the Heavy-Duty Diesel In-Use Compliance Program, the Public Bus Fleet Rule and Engine Standards, and the School Bus Program and others.6 California In-Use Off-Road Diesel Vehicle Regulation On July 26, 2007, the ARB adopted a regulation to reduce DPM and NOX emissions from in-use (existing) off-road heavy-duty diesel vehicles in California. Such vehicles are used in construction, mining, and industrial operations. The regulation limits idling to no more than five consecutive minutes, requires reporting and labeling, and requires disclosure of the regulation upon vehicle sale. The ARB is enforcing that part of the rule with fines up to $10,000 per day for each vehicle in violation. Performance requirements of the rule are based on a fleet’s average NOX emissions, which can be met by replacing older vehicles with newer, cleaner vehicles or by applying exhaust retrofits. The regulation was amended in 2010 to delay the original timeline of the performance requirements, making the first compliance deadline January 1, 2014, for large fleets (over 5,000 horsepower), 2017 for medium fleets (2,501-5,000 horsepower), and 2019 for small fleets (2,500 horsepower or less). The regulation applies to nearly all privately and federally owned diesel-fueled trucks and buses, and to privately and publicly owned school buses with a gross vehicle weight rating greater than 14,000 pounds. The regulation provides a variety of flexibility options tailored to fleets operating low use vehicles, fleets operating in selected vocations like agricultural and construction, and small fleets of three or fewer trucks.7 5 California Air Resources Board (ARB). 2021.

If there is a safe threshold for a substance at which there is no toxic effect, the control measure must reduce exposure below that threshold. If there is no safe threshold, the measure must incorporate Best Available Control Technology to minimize emissions. In July 2001, the ARB approved an ATCM for construction, grading, quarrying and surface mining operations to minimize emissions of naturally occurring asbestos. The regulation requires application of Best Management Practices (BMPs) to control fugitive dust in areas known to have naturally occurring asbestos and requires notification to the local air district prior to commencement of ground-disturbing activities. The measure establishes specific testing, notification and engineering controls prior to grading, quarrying, or surface mining in construction zones where naturally occurring asbestos is located on projects of any size. There are additional notification and engineering controls at work sites larger than one acre in size. These projects require the submittal of a “Dust Mitigation Plan” and approval by the ARB prior to the start of a project. Construction sometimes requires the demolition of existing buildings where construction occurs. Asbestos is also naturally occurring. Exposure and disturbance of rock and soil that naturally contain asbestos can result in the release of fibers into the air and consequent exposure to the public. Asbestos most commonly occurs in ultramafic rock that has undergone partial or complete alteration to serpentine rock (serpentinite) and often contains chrysotile asbestos. In addition, another form of asbestos, tremolite, is associated with ultramafic rock, particularly near faults. Sources of asbestos emissions include unpaved roads or driveways surfaced with ultramafic rock, construction activities in ultramafic rock deposits, or rock quarrying activities where ultramafic rock is present. The ARB has an ATCM for construction, grading, quarrying, and surface mining operations, requiring the implementation of mitigation measures to minimize emissions of asbestos-laden dust. The measure applies to road construction and maintenance, construction and grading operations, and quarries and surface mines when the activity occurs in an area where naturally occurring asbestos is likely found. Areas are subject to the regulation if they are identified on maps published by the United States Geological Survey (USGS) as ultramafic rock units or if the Air Pollution Control Officer or owner/operator has knowledge of the presence of ultramafic rock, serpentine, or naturally occurring asbestos on the site. The measure also applies if ultramafic rock, serpentine, or asbestos is discovered during any operation or activity. Review of USGS maps indicates that no ultramafic rock has been found near the project site with areas more likely to contain naturally occurring asbestos approximately 3 miles southeast of the project site in the area around Shell Ridge Open Space and Diablo Foothills Regional Park.8 Verified Diesel Emission Control Strategies The EPA and the ARB tiered off-road emission standards only apply to new engines and off-road equipment can last several years. The ARB has developed Verified Diesel Emission Control Strategies (VDECS), which are devices, systems, or strategies used to achieve the highest level of pollution 8 United States Geological Survey. 2011.

VDECS are designed primarily for the reduction of DPM emissions and have been verified by ARB. There are three levels of VDECS, the most effective of which is the Level 3 VDECS. Tier 4 engines are not required to install VDECS because they already meet the emissions standards for lower tiered equipment with installed controls. California Diesel Risk Reduction Plan The ARB Diesel Risk Reduction Plan has led to the adoption of new State regulatory standards for all new on-road, off-road, and stationary diesel-fueled engines, and vehicles to reduce DPM emissions in 2020 by about 90 percent overall from year 2000 levels. The projected emission benefits associated with the full implementation of this plan, including federal measures, are reductions in DPM emissions and associated cancer risks of 75 percent by 2010, and 85 percent by 2020.9 Tanner Air Toxics Act and Air Toxics Hot Spots Information and Assessment Act TACs in California are primarily regulated through the Tanner Air Toxics Act (AB 1807) and the Air Toxics Hot Spots Information and Assessment Act of 1987 (AB 2588), also known as the Hot Spots Act. To date, the ARB has identified more than 21 TACs, and has adopted the EPA’s list of Hazardous Air Pollutants (HAPs) as TACs. Carl Moyer Memorial Air Quality Standards Attainment Program The Carl Moyer Memorial Air Quality Standards Attainment Program (Carl Moyer Program), a partnership between the ARB and local air districts, issues grants to replace or retrofit older engines and equipment with engines and equipment that exceed current regulatory requirements to reduce air pollution. Money collected through the Carl Moyer Program complements California’s regulatory program by providing incentives to effect early or extra emission reductions, especially from emission sources in environmental justice communities and areas disproportionately affected by air pollution. The program has established guidelines and criteria for the funding of emissions reduction projects. Within the Air Basin, the BAAQMD administers the Carl Moyer Program. The program has established guidelines and criteria for the funding of emissions reduction projects and has established cost- effectiveness criteria for funding emission reductions projects, which under the final 2017 Carl Moyer Program Guidelines are $30,000 per weighted ton of NOX, ROG, and PM.10 Regional BAAQMD California Environmental Quality Act Air Quality Guidelines The BAAQMD is the primary agency responsible for ensuring that air quality standards (NAAQS and CAAQS) are attained and maintained in the Air Basin through a comprehensive program of planning, regulation, enforcement, technical innovation, and promotion of the understanding of air quality issues.

The BAAQMD developed quantitative thresholds of significance for its California Environmental Quality Act (CEQA) Guidelines in 2010, which were also included in its updated 2011 Guidelines. The BAAQMD’s adoption of the 2010 thresholds of significance was later challenged in court. In an opinion issued on December 17, 2015, related to the BAAQMD CEQA Guidelines, the California Supreme Court held that CEQA does not generally require an analysis of the impacts of locating development in areas subject to environmental hazards unless the proposed project would exacerbate existing environmental hazards. The California Supreme Court also found that CEQA requires the analysis of exposing people to environmental hazards in specific circumstances, including the location of development near airports, schools near sources of toxic contamination, and certain exemptions for infill and workforce housing. The California Supreme Court also held that public agencies remain free to voluntarily conduct this analysis not required by CEQA for their own public projects (CBIA v. BAAQMD (2016) 2 Cal. App.5th 1067, 1083). In view of the California Supreme Court’s opinion, the BAAQMD published a new version of its CEQA Guidelines in May 2017. The BAAQMD CEQA Guidelines state that local agencies may rely on thresholds designed to reflect the impact of locating development near areas of toxic air contamination where such an analysis is required by CEQA, or where the agency has determined that such an analysis would assist in making a decision about the proposed project. However, the thresholds are not mandatory, and agencies should apply them only after determining that they reflect an appropriate measure of a project’s impacts. The BAAQMD’s guidelines for implementation of the thresholds are for informational purposes only, to assist local agencies. BAAQMD Particulate Matter Plan To fulfill federal air quality planning requirements, the BAAQMD adopted a PM2.5 emissions inventory for year 2010 at a public hearing on November 7, 2012. The Bay Area Clean Air Plan also included several measures for reducing PM emissions from stationary sources and woodburning. On January 9, 2013, the EPA issued a Final Rule determining that the Bay Area has attained the 24-hour PM2.5 NAAQS, suspending federal SIP planning requirements for the Air Basin.11 Despite this EPA action, the Air Basin will continue to be designated as non-attainment for the national 24-hour PM2.5 standard until the BAAQMD submits a redesignation request and a maintenance plan to the EPA, and the EPA approves the proposed redesignation. The Air Basin is designated non-attainment for the State PM10 and PM2.5 standards, but it is currently unclassified for the federal PM10 standard and non-attainment for federal PM2.5 standards. The EPA lowered the 24-hour PM2.5 standard from 65 µg/m3 to 35 µg/m3 in 2006, and designated the Air Basin as non-attainment for the new PM2.5 standard effective December 14, 2009. 11 United States Environmental Protection Agency (EPA). 2013.

If the clean data finding request is approved, then EPA guidelines provide that the region can fulfill federal PM2.5 SIP requirements by preparing either a redesignation request and a PM2.5 maintenance plan, or a “clean data” SIP submittal. Because peak PM2.5 levels can vary from year to year based on natural, short-term changes in weather conditions, the BAAQMD believes that it would be premature to submit a redesignation request and PM2.5 maintenance plan at this time. Therefore, the BAAQMD will prepare a “clean data” SIP to address the required elements, including: • An emission inventory for primary PM2.5, as well as precursors to secondary PM formation • Amendments to the BAAQMD’s New Source Review regulation to address PM2.5 BAAQMD 2017 Clean Air Plan On May 2017, the BAAQMD adopted the final Bay Area 2017 Clean Air Plan. The BAAQMD prepared the 2017 Clean Air Plan in cooperation with the Metropolitan Transportation Commission (MTC) and the Association of Bay Area Governments (ABAG). The goals of the 2017 Clean Air Plan are to reduce regional air pollutants and climate pollutants to improve the health of Bay Area residents for the next decades. The 2017 Clean Air Plan aims to lead the region into a post-carbon economy, continue progress toward attaining all State and federal air quality standards, and eliminate health risk disparities from air pollution exposure in Bay Area communities. The Plan includes 85 distinct control measures to help the region reduce air pollutants and has a long-term strategic vision that forecasts what a clean air Bay Area will look like in year 2050. The 2017 Clean Air Plan envisions a future whereby the year 2050: • Buildings will be energy efficient—heated, cooled and powered by renewable energy. • Transportation will be a combination of electric vehicles, both shared and privately owned; autonomous public transit fleets; with a large share of trips by bicycling, walking, and transit. • The Bay Area will be powered by clean, renewable electricity and will be a leading incubator and producer of clean energy technologies leading the world in the carbon-efficiency of our products. • Bay Area residents will have developed a low-carbon lifestyle by driving electric vehicles, living in zero net energy homes, eating low-carbon foods, and purchasing goods and services with low-carbon content. • Waste will be greatly reduced, waste products will be re-used or recycled, and all organic waste will be composted and put to productive use. The focus of control measures includes aggressively targeting the largest source of GHG, ozone pollutants and PM emissions—transportation. This includes more incentives for electric vehicle infrastructure, off-road electrification projects such as Caltrain and shore power at ports, and reducing emissions from trucks, school buses, marine vessels, locomotives, and off-road equipment. Additionally, the BAAQMD will continue to work with regional and local governments to reduce Vehicle Miles Traveled (VMT) through the further funding of rideshare, bike and shuttle programs.

Each emergency generator installed is assumed to meet a minimum of Tier 2 emission standards (before control measures). As part of the permitting process, the BAAQMD limits the excess cancer risk from any facility to no more than 10 per 1-million-population for any permits that are applied for within a 2-year period and would require any source that would result in an excess cancer risk greater than 1 per 1 million to install Best Available Control Technology (BACT) for Toxics. Regulation 8, Rule 3 (Architectural Coatings) This rule governs the manufacture, distribution, and sale of architectural coatings and limits the ROG content in paints and paint solvents. Although this rule does not directly apply to the proposed project, it does dictate the ROG content of paint available for use during the construction. Regulation 8, Rule 15 (Emulsified and Liquid Asphalts) Although this rule does not directly apply to the proposed project, it does dictate the reactive organic gases content of asphalt available for use during the construction through regulating the sale and use of asphalt and limits the ROG content in asphalt. Regulation 1, Rule 301 (Odorous Emissions) The BAAQMD is responsible for investigating and controlling odor complaints in the Bay Area. The agency enforces odor control by helping the public to document a public nuisance. Upon receipt of a complaint, the BAAQMD sends an investigator to interview the complainant and to locate the odor source if possible. The BAAQMD typically brings a public nuisance court action when there are a substantial number of confirmed odor events within a 24-hour period. An odor source with five or more confirmed complaints per year, averaged over 3 years is considered to have a substantial effect on receptors. Several BAAQMD regulations and rules apply to odorous emissions. Regulation 1, Rule 301 is the nuisance provision that states that sources cannot emit air contaminants that cause nuisance to a number of persons. Regulation 7 specifies limits for the discharge of odorous substances where the BAAQMD receives complaints from 10 or more complainants within a 90-day period. Among other things, Regulation 7 precludes discharge of an odorous substance that causes the ambient air at or beyond the property line to be odorous after dilution with four parts of odor-free air, and specifies maximum limits on the emission of certain odorous compounds. Plan Bay Area On July 18, 2013, ABAG and the MTC approved the Plan Bay Area. The Plan Bay Area includes integrated land use and transportation strategies for the region and was developed through OneBayArea, a joint initiative between ABAG, BAAQMD, MTC, and the San Francisco Bay 12 Bay Area Air Quality Management District (BAAQMD). 2016.

The plan’s transportation policies focus on maintaining the extensive existing transportation network and utilizing these systems more efficiently to handle density in Bay Area transportation cores.13 Assumptions for land use development come from local and regional planning documents. Emission forecasts in the Bay Area Clean Air Plan rely on projections of VMT, population, employment, and land use projections made by local jurisdictions during development of Plan Bay Area. The Plan Bay Area 2040 was adopted July 2017 and updates Plan Bay Area. Plan Bay Area 2040, published by the MTC and ABAG, is a long-range integrated transportation and land use/housing strategy through 2040 for the Bay Area. Plan Bay Area 2040 functions as the sustainable communities’ strategy mandated by Senate Bill (SB) 375. As a regional land use plan, Plan Bay Area 2040 aims to reduce per capita GHG emissions through the promotion of more compact, mixed-use residential and commercial neighborhoods located near transit. Plan Bay Area 2040 is a limited and focused update that builds upon a growth pattern and strategies developed in the original Plan Bay Area (adopted by MTC in 2013) but with updated planning assumptions that incorporate key economic, demographic, and financial trends from the last 4 years. Contra Costa County Contra Costa County General Plan The Contra Costa County General Plan (General Plan) establishes goals, objectives, and policies associated with air quality.

Would the project: a) Conflict with or obstruct implementation of the applicable air quality plan? b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or State ambient air quality standard? c) Expose sensitive receptors to substantial pollutant concentrations? d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? BAAQMD Significance Criteria The BAAQMD CEQA Air Quality Guidelines were prepared to assist in the evaluation of air quality impacts of projects and plans proposed within the Bay Area. The guidelines provide recommended procedures for evaluating potential air impacts during the environmental review process, consistent with CEQA requirements, and include recommended thresholds of significance, mitigation measures, and background air quality information. They also include recommended assessment methodologies for air toxics, odors, and GHGs. In June 2010, the BAAQMD's Board of Directors adopted CEQA thresholds of significance and an update of the CEQA Guidelines. These thresholds are designed to establish the level at which the BAAQMD believed air pollution emissions would cause significant environmental impacts under CEQA. The updated BAAQMD CEQA Air Quality Guidelines were amended in June 2011 to include a risk and hazards threshold for new receptors and modified procedures for assessing impacts related to risk and hazard impacts. However, this later amendment regarding risk and hazards was the subject of the December 17, 2015, California Supreme Court decision (California Building Industry Association v BAAQMD (2015) 62 Cal.4th 369), which clarified that CEQA generally does not require an evaluation of impacts of the environment on a project’s future users or residents. The California Supreme Court also found that CEQA requires the analysis of exposing people to environmental hazards in specific circumstances, including the location of development near airports, schools near sources of toxic contamination, and certain exemptions for infill and workforce housing. Additionally, it also held that public agencies remain free to conduct this analysis regardless of whether it is required by CEQA. To account for these updates, the BAAQMD published a new version of the Contra Costa County—Oak Road Townhouse Condominiums Project Draft EIR Air Quality FirstCarbon Solutions 3.2-29 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx Guidelines dated May 2017, which includes revisions made to address the Supreme Court’s opinion.14 This latest version of the BAAQMD CEQA Guidelines was used to prepare the analysis in this Draft EIR. Regional Significance Criteria The BAAQMD’s criteria for regional significance for projects that exceed the screening thresholds are shown in Table 3.2-7. Criteria for both the construction and operational phases of the proposed project are shown. Table 3.2-7: BAAQMD Regional (Mass Emissions) Air Pollutant Significance Thresholds Pollutant Construction Phase Operational Phase Average Daily Emissions (pounds/day) Average Daily Emissions (pounds/day) Maximum Annual Emissions (tons/year) ROG 54 54 10 NOX 54 54 10 PM10 82 (Exhaust) 82 15 PM2.5 54 (Exhaust) 54 10 PM10 and PM2.5 Fugitive Dust Best Management Practices None None Notes: ROG = reactive organic gas NOX = oxides of nitrogen PM10 = particulate matter, including dust, 10 micrometers or less in diameter PM2.5 = particulate matter, including dust, 2.5 micrometers or less in diameter Source: Bay Area Air Quality Management District (BAAQMD) 2017. May. California Environmental Quality Act (CEQA) Air Quality Guidelines. If a project were to exceed the emissions in Table 3.2-7, emissions would cumulatively contribute to the non-attainment status and would contribute to elevating health effects associated with these criteria air pollutants. Known health effects related to ozone include worsening of bronchitis, asthma, and emphysema and a decrease in lung function. Health effects associated with PM include premature death of people with heart or lung disease, nonfatal heart attacks, irregular heartbeat, decreased lung function, and increased respiratory symptoms. Reducing emissions would further contribute to reducing possible health effects related to criteria air pollutants. However, for projects that exceed the emissions in Table 3.2-7, it is speculative to determine how exceeding the regional thresholds would affect the number of days the region is in non-attainment—since mass emissions are not correlated with concentrations of emissions—or how many additional individuals in the Air Basin would be affected by the health effects cited above. 14 Bay Area Air Quality Management District (BAAQMD). 2017.

County of Fresno (Friant Ranch, LP) (2018) 6 Cal. 5th 502, Case No. S21978. Ozone concentrations are dependent upon a variety of complex factors, including the presence of sunlight and precursor pollutants, natural topography, nearby structures that cause building downwash, atmospheric stability, and wind patterns. Because of the complexities of predicting ground-level ozone concentrations in relation to the NAAQS and CAAQS, it is not possible to link health risks to the magnitude of emissions exceeding the significance thresholds. To achieve the health-based standards established by the EPA, the air districts prepare air quality management plans that detail regional programs to attain the AAQS. However, if a project within the BAAQMD exceeds the regional significance thresholds, the proposed project could contribute to an increase in health effects in the basin until the attainment standards are met in the Air Basin. Consistency with Air Quality Plan The applicable air quality plan is BAAQMD’s 2017 Bay Area Clean Air Plan, which identifies measures to: • Reduce emissions and reduce ambient concentrations of air pollutants. • Safeguard public health by reducing exposure to the air pollutants that pose the greatest health risk, with an emphasis on protecting the communities most heavily affected by air pollution. • Reduce GHG emissions to protect the climate. A project would be determined to conflict with or obstruct implementation of an applicable air quality plan if it would result in substantial new regional emissions not foreseen in the air quality planning process. Local CO Hotspots Congested intersections have the potential to create elevated concentrations of CO, referred to as CO hotspots. The significance criteria for CO hotspots are based on the CAAQS for CO, which is 9.0 ppm (8-hour average) and 20.0 ppm (1-hour average). However, with the turnover of older vehicles, introduction of cleaner fuels, and implementation of control technology, the Air Basin is in attainment of the CAAQS and NAAQS, and CO concentrations in the Air Basin have steadily declined. Because CO concentrations have improved, the BAAQMD does not require a CO hotspot analysis if the following criteria are met: • The project is consistent with an applicable congestion management program established by the County Congestion Management Agency for designated roads or highways, the regional transportation plan, and local congestion management agency plans. Contra Costa County—Oak Road Townhouse Condominiums Project Draft EIR Air Quality FirstCarbon Solutions 3.2-31 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx • The project would not increase traffic volumes at affected intersections to more than 44,000 vehicles per hour. • The project traffic would not increase traffic volumes at affected intersection to more than 24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited (e.g., tunnel, parking garage, bridge underpass, natural or urban street canyon, below-grade roadway).15 Community Risk and Hazards The BAAQMD’s significance thresholds for local community risk and hazard impacts apply to both the siting of a new source and to the siting of a new receptor. Local community risk and hazard impacts are associated with TACs and PM2.5 because emissions of these pollutants can have significant health impacts at the local level. The proposed project would generate TACs and PM2.5 during construction activities that could elevate concentrations of air pollutants at the nearby school and residential sensitive receptors. The thresholds for construction-related local community risk and hazard impacts are the same as for project operations. The BAAQMD has adopted screening tables for air toxics evaluation during construction.16 Construction-related TAC and PM2.5 impacts should be addressed on a case-by-case basis, taking into consideration the specific construction-related characteristics of each project and proximity to off-site receptors, as applicable.17 Since the County does not have a qualified risk reduction plan, a site-specific analysis of TACs and PM2.5 impacts on sensitive receptors was conducted. The thresholds identified below are applied to the proposed project’s construction and operational phases. Community Risk and Hazards: Project Project-level emissions of TACs or PM2.5 from individual sources that exceed any of the thresholds listed below are considered a potentially significant community health risk: • An excess cancer risk level of more than 10 in one million, or a non-cancer (i.e., chronic, or acute) HI greater than 1.0 would be a significant cumulatively considerable contribution. • An incremental increase of greater than 0.3 micrograms per cubic meter (μg/m3) annual average PM2.5 from a single source would be a significant cumulatively considerable contribution. 15 Bay Area Air Quality Management District (BAAQMD). 2017.

A project would have a cumulative considerable impact if the aggregate total of all past, present, and foreseeable future sources within a 1,000-foot radius from the fence line of a source or location of a receptor, plus the contribution from the proposed project, meets any of these conditions: • Has excess cancer risk levels of more than 100 in one million or a chronic non-cancer HI (from all local sources) greater than 10.0. • Exceeds 0.8 μg/m3 annual average PM2.5. In February 2015, Office of Environmental Health Hazard Assessment (OEHHA) adopted new health risk assessment guidance that includes several efforts to be more protective of children’s health. These updated procedures include the use of age sensitivity factors to account for the higher sensitivity of infants and young children to cancer-causing chemicals, and age-specific breathing rates.18 Odors The BAAQMD thresholds for odors are qualitative based on BAAQMD Regulation 7, Odorous Substances. This rule places general limitations on odorous substances and specific emission limitations on certain odorous compounds. Odors are also regulated under BAAQMD Regulation 1, Rule 1-301, Public Nuisance, which states that no person shall discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or the public; or which endangers the comfort, repose, health, or safety of any such persons or the public, or which causes, or has a natural tendency to cause, injury, or damage to business or property. Under BAAQMD’s Rule 1-301, the BAAQMD has established odor screening thresholds for land uses that have the potential to generate substantial odor complaints, including wastewater treatment plants, landfills or transfer stations, composting facilities, confined animal facilities, food manufacturing, and chemical plants. Table 3.2-8 shows the screening distances for various land uses that are considered to have objectionable odors.19 Table 3.2-8: BAAQMD Odor Screening-level Distances Thresholds Land Use/Type of Operation Project Screening Distance Wastewater Treatment Plant 2 miles Wastewater Pumping Facilities 1 mile Sanitary Landfill 2 miles 18 Office of Environmental Health Hazard Assessment (OEHHA). 2015.

Approach to Analysis Emission factors represent the emission rate of a pollutant over a given time or activity; for example, grams of NOX per VMT or grams of NOX per horsepower hour of equipment operation. The ARB has published emission factors for on-road mobile vehicles/trucks in the EMission FACtors (EMFAC ) mobile source emissions model and emission factors for off-road equipment and vehicles in the OFFROAD emissions model. Activity levels are a measure of how active a piece of equipment is and can be represented as the amount of material processed, elapsed time that a piece of equipment is in operation, horsepower of a piece of equipment used, or VMT per day. An air emissions model (or calculator) combines the emission factors and the various levels of activity and outputs the emissions for the various pieces of equipment. The California Emissions Estimator Model (CalEEMod) Version 2016.3.2 was developed in collaboration with the South Coast Air Quality Management District and other air districts throughout the State. CalEEMod is designed as a uniform platform for government agencies, land use planners, and environmental professionals to quantify potential criteria pollutant emissions associated with construction and operation from a variety of land uses. The modeling follows BAAQMD guidance where applicable from its CEQA Air Quality Guidelines. The models used in this analysis are summarized as follows: • Construction criteria pollutant and precursor emissions: CalEEMod, Version 2016.3.2 • Operational criteria pollutant and precursor emissions: CalEEMod, Version 2016.3.2 • Construction TAC emission air dispersion assessment: EPA AERMOD dispersion model, Version 18081 Contra Costa County—Oak Road Townhouse Condominiums Project Air Quality Draft EIR 3.2-34 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx The following criteria air pollutants and precursors are assessed in this analysis: • Reactive organic gas (ROG) • Nitrogen oxides (NOX) • Carbon monoxide (CO) • Particulate matter equal to or less than 10 microns in diameter (PM10) • Particulate matter equal to or less than 2.5 microns in diameter (PM2.5) Note that the proposed project would emit ozone precursors ROG and NOX. However, the proposed project would not directly emit ozone since it is formed in the atmosphere during the photochemical reactions of the ozone precursors. Project-specific data included the size of the project site and the construction schedule. For the purpose of this analysis, construction of the proposed project was assumed to begin in September 2022 and continue through November 2023. These data also included estimated project trip generation and trip length provided by Hexagon Transportation Consultants, Inc.20 (see Appendix I). Data specific to the BAAQMD included use of architectural coatings with 100 grams per liter (g/l) ROG content, consistent with BAAQMD Regulation 8 Rule 3. Construction-related Criteria Pollutants Construction emissions can vary substantially from day to day, depending on the level of activity, the specific type of operation, and prevailing weather conditions. Construction emissions result from both on-site and off-site activities. On-site emissions consist of exhaust emissions from the activity levels of heavy-duty construction equipment, motor vehicle operation, and fugitive dust (mainly PM10) from disturbed soil. Additionally, paving operations and application of architectural coatings would release ROG emissions. Off-site emissions result from motor vehicle exhaust from delivery vehicles, worker traffic, and road dust (PM10 and PM2.5). Equipment Tiers and Emission Factors Equipment tiers refer to a generation of emission standards established by the EPA and ARB that apply to diesel engines in off-road equipment. The “tier” of an engine depends on the model year and horsepower rating; generally, the newer a piece of equipment is, the greater the tier it is likely to have. Excluding engines greater than 750 horsepower, Tier 1 engines were manufactured generally between 1996 and 2003. Tier 2 engines were manufactured between 2001 and 2007. Tier 3 engines were manufactured between 2006 and 2011. Tier 4 engines are the newest and some incorporate hybrid electric technology; they have been manufactured since 2007. Construction emissions are generally calculated as the product of an activity factor and an emission factor. The activity factor for construction equipment is a measure of how active a piece of equipment is and can be represented as the amount of material processed, elapsed time that a piece of equipment is in operation, horsepower of a piece of equipment used, or the amount of fuel consumed in a given amount of time. The emission factor relates the process activity to the amount of pollutant emitted. Examples of emission factors include grams of emissions per miles traveled and 20 Hexagon Transportation Consultants, Inc. 2021.

The operation of a piece of equipment is tempered by its load factor which is the average power of a given piece of equipment while in operation compared with its maximum rated horsepower. A load factor of 1.0 indicates that a piece of equipment continually operates at its maximum operating capacity. This analysis uses the CalEEMod default load factors for off-road equipment. Operation-related Criteria Pollutants The operational phase emissions are based on development of the proposed project. The modeling accounts for the average daily vehicle and VMT, energy usage, water demand, and wastewater and solid waste generation. For purposes of this analysis, hours of operation for the proposed project are 24 hours per day, 7 days per week. Transportation CalEEMod Version 2016.3.2 was used to quantify mobile source emissions using derived vehicle emission rates based on vehicle emissions data obtained from the ARB EMFAC2021 web database. The project-specific daily trip generation rate for Multi-family Housing–Midrise (Institute of Transportation Engineers Land Use Code 221) were provided by Hexagon Transportation Consultants.21 Saturday and Sunday trip rates were assumed to be the weekday rate adjusted by multiplying the ratio of the CalEEMod default rates for Saturday and Sunday trips to the default weekday rate. Default trip lengths and trip types specified by CalEEMod for each input land use were used for the emissions estimates. The proposed project is estimated to generate 1,180 gross daily vehicle trips, with 93 gross trips occurring during the AM peak-hour and 124 gross trips during the PM peak-hour. Other Operational Emissions Solid Waste Disposal. Indirect emissions from waste generation are based on the CalEEMod default solid waste generation rates, which are based on data from the California Department of Resources, Recycling, and Recovery (CalRecycle). Water/Wastewater. GHG emissions from this sector are associated with the embodied energy used to supply water, treat water, distribute water, and then treat wastewater and fugitive GHG emissions from wastewater treatment. Indoor water consumption is based on CalEEMod default indoor water use rates. Area Sources. Area and stationary sources are based on the CalEEMod defaults for use of consumer products and cleaning supplies. Energy. CalEEMod defaults for energy use were used, which include the 2016 Title 24 Building Standards. GHG emissions modeling includes those indirect emissions from electricity consumption. The electricity produced emission rates were modified in CalEEMod. CalEEMod has a default emission factor of 641.3 pounds of CO2 per megawatt of electricity produced, which is based on Pacific Gas and Electric’s (PG&E) 2008 emissions rate. However, in 2019, PG&E published emissions rates for 2010 through 2017, which showed the emission rate for delivered electricity had been 21 Hexagon Transportation Consultants, Inc. 2021.

The project is designed be all-electric construction in the new homes with no natural gas provided. Each home will have roof-top solar panels. The number and orientation of the panels will vary from unit to unit. Construction- and Operation-related Toxic Air Contaminants TACs are air pollutants in minuscule amounts in the air that, if a person receives exposure to them, could increase the chances of experiencing health problems. Exposures to TAC emissions can have both chronic long-term (over a year or longer) and acute short-term (over a period of hours) health impacts. Construction-period TAC emissions could contribute to increased health risks to nearby residents or sensitive receptors. The County assessed the potential health impacts to surrounding sensitive receptors resulting from TAC emissions during project construction. The TACs of greatest concern are those that cause serious health problems or affect many people. Health problems can include cancer, respiratory irritation, nervous system problems, and birth defects. Some health problems occur soon after a person inhales TACs. These immediate effects may be minor, such as watery eyes; or they may be serious, such as life-threatening lung damage. Other health problems may not appear until many months or years after a person’s first exposure to the TAC. Cancer is one example of a delayed health problem. Fine particle pollution can be emitted directly or formed secondarily in the atmosphere. PM2.5 health impacts are important because their size can be deposited deeply in the lungs causing respiratory effects. For purposes of this analysis, exhaust emissions of DPM, are represented as exhaust emissions of PM2.5. Studies indicate that DPM poses the greatest health risk among airborne TACs. A 10-year research program conducted by the ARB demonstrated that DPM from diesel-fueled engines is a human carcinogen and that chronic (long-term) inhalation exposure to DPM poses a chronic long-term health risk. DPM differs from other TACs in that it is not a single substance but a complex mixture of hundreds of substances. Although diesel-fueled, internal combustion engines emit DPM, the composition of the emissions varies, depending on engine type, operating conditions, fuel composition, lubricating oil, and whether an emission control system is present. The CalEEMod emissions model has been used to estimate construction-related emissions. Odors The impact analysis qualitatively evaluates the types of land uses proposed to evaluate whether major sources of anticipated odors would be present and, if so, whether those sources would likely generate objectionable odors. According to the BAAQMD’s CEQA Air Quality Guidelines, a project that involves the siting of a new odor source would consider the screening-level distances and the complaint history of the odor sources, described below. Projects that would site a new odor source farther than the screening-level distances provided in Table 3.2-8 would not likely result in a significant odor impact. 22 Pacific Gas and Electric Company (PG&E). 2019.

Impact Analysis The BAAQMD is responsible for reducing emissions from area, stationary, and mobile sources in the Air Basin to achieve NAAQS and CAAQS. The BAAQMD 2017 Clean Air Plan is a regional and multiagency effort to reduce air pollution in the Air Basin. A consistency determination with the BAAQMD plays an important role in local agency project review by linking local planning and individual projects to the 2017 Clean Air Plan. It fulfills the CEQA goal of informing decision makers of the environmental efforts of the proposed project under consideration early enough to ensure that air quality concerns are fully addressed. It also provides the local agency with ongoing information as to whether they are contributing to the clean air goals in the 2017 Clean Air Plan. The regional emissions inventory for the Air Basin is compiled by the BAAQMD. Regional population, housing, and employment projections developed by ABAG are based, in part, on cities and counties’ general plan land use designations. These projections form the foundation for the emissions inventory of the 2017 Clean Air Plan. These demographic trends are incorporated into Plan Bay Area, compiled by ABAG and the MTC to determine priority transportation projects and VMT in the Bay Area. The 2017 Clean Air Plan strategy is based on projections from local general plans. Projects that are consistent with the local general plan are considered consistent with the regional air quality plan. Large projects that exceed regional employment, population, and housing planning projections have the potential to be inconsistent with the regional inventory compiled as part of the 2017 Clean Air Plan. A project would be judged to conflict with or obstruct the 2017 Clean Air Plan implementation if it would result in substantial new regional emissions not foreseen in the air quality planning process. The BAAQMD does not provide a numerical threshold of significance for project-level consistency analysis with AQPs. Therefore, the following criteria will be used for determining a project’s consistency with the AQP. • Criterion 1: Does the project support the primary goals of the AQP? • Criterion 2: Does the project include applicable control measures from the AQP? • Criterion 3: Does the project disrupt or hinder implementation of any AQP control measures? Criterion 1 The primary goals of the 2017 Clean Air Plan, the current AQP to date, are to: • Attain air quality standards; • Reduce population exposure to unhealthy air and protecting public health in the Bay Area; and • Reduce GHG emissions and protect the climate. Contra Costa County—Oak Road Townhouse Condominiums Project Air Quality Draft EIR 3.2-38 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx A measure for determining whether the proposed project supports the primary goals of the AQP is if the proposed project would result in an increase in the frequency or severity of existing air quality violations, cause or contribute to new violations, or delay timely attainment of air quality standards or the interim emission reductions specified in the AQPs. The development of the AQP is based, in part, on the general plan land use determinations of the various cities and counties that constitute the Air Basin. As described in Impact LAND-2, the General Plan designates the project site as Multiple-Family Residential High (MH). The MH designation allows for densities between 22.0 and 29.9 multiple-family units per net acre. Primary land uses include attached single-family residences, multiple-family residences including condominiums, town houses, and apartments, as well as accessory buildings and structures ancillary to the primary uses. The proposed project would develop 125 townhouse condominiums, resulting in a total of 237,816 square feet of net new habitable construction on 5.94 acres or a net density of 26.3 dwelling unit per acre. Therefore, the density and use would be consistent with the General Plan land use designation and the proposed project would not require a General Plan Amendment. The proposed project includes construction of 125 townhouse condominium units located in 19 three-story townhome condominium buildings. As the project site is 5.94 acres, the proposed project would introduce a residential density of approximately 21 units per acre, which is within the currently allowed density for the site. As such, the proposed project would not introduce a greater amount of population growth than what was envisioned by the General Plan and, subsequently, the AQP. Therefore, the anticipated population growth facilitated by the proposed project was anticipated in the 2017 Clean Air Plan and the project would not conflict with the goals contained in the AQP. Moreover, as further discussed under Impacts AIR-2 and AIR-3, the proposed project’s construction and operational-related emissions would not exceed BAAQMD’s project-level thresholds and would, therefore, not create a localized violation of State or federal air quality standards with implementation of Mitigation Measure (MM) AIR-2 and MM AIR-3. Therefore, the proposed project would be consistent with Criterion 1 with implementation of mitigation measures, as identified under Impact AIR-2 and AIR-3. The proposed project is therefore consistent with Criterion 1 after incorporation of identified mitigation. Criterion 2 The 2017 Clean Air Plan contains 85 control measures that describe specific actions to reduce air pollutants and GHGs at the local, regional, and global levels. Along with the traditional stationary, area, mobile source, and transportation control measures, the 2017 Clean Air Plan contains several control measures designed to protect the climate, promote mixed use, and compact development to reduce vehicle emissions and exposure to pollutants from stationary and mobile sources. The 2017 Clean Air Plan also includes an account of the implementation status of control measures identified in the 2010 Clean Air Plan. Table 3.2-9 lists the relevant Clean Air Plan policies to the proposed project and evaluates the proposed project’s consistency with the policies. As shown below, the proposed project would be consistent with applicable measures.

Therefore, any new stationary sources associated with the proposed project would be required to comply with BAAQMD’s regulations. Based on the proposed residential use for the project site, it is not anticipated that the proposed project would result in any new major stationary source emissions. Additionally, in the event stationary equipment is installed on-site, it is anticipated that the equipment would be small-quantity emitters and would require review by BAAQMD for permitted sources of air which would ensure consistency with the 2017 Clean Air Plan.

Compliance with the 2019 Building Energy Efficiency Standards would also improve energy efficiency by 10.7 percent and 1 percent for electricity and natural gas, respectively, compared to the 2016 Building Energy Efficiency Standards. Therefore, implementation of the proposed project would not conflict with these EN control measures.

Natural and Working Lands Control Measures NW 1–Carbon Sequestration in Rangelands NW 2–Urban Tree Planting NW 3–Carbon Sequestration in Wetlands The control measures for the Natural and Working Lands (NW) sector focus on increasing carbon sequestration on rangelands and wetlands. The proposed project would include the planting of various ornamental and shade trees throughout the project site. Waste Management Control Measures WA 1–Landfills WA 2–Composting and Anaerobic Digesters WA 3–Green Waste Diversion WA 4–Recycling and Waste Reduction The Waste Management (WA) control measures include strategies to increase waste diversion rates through efforts to reduce, reuse, and recycle. The proposed project would comply with the requirements of AB 341. Additionally, the proposed project would reduce construction waste by 75 percent and use 30 percent recycled content during construction of the proposed facility. Therefore, the proposed project would not conflict with these WA control measures. Water Control Measures WR 1–Limit GHGs from publicly owned treatment works (POTWs) WR 2–Support Water Conservation The 2017 Clean Air Plan includes measures to reduce water use.

In summary, the proposed project would not conflict with or hinder BAAQMD from implementing the control measures in 2017 Clean Air Plan and impacts would be less than significant.

Table 3.2-9 in Criterion 2 illustrates that the proposed project would incorporate several AQP control measures as project design features. Considering this information, the proposed project would not disrupt or hinder the implementation of any AQP control measures. Therefore, the proposed project would be consistent with Criterion 3. Summary As discussed above, the proposed project would be consistent with all three criteria after the incorporation of identified mitigation. Thus, the proposed project would not conflict with the 2017 Clean Air Plan. Therefore, impacts associated with conflicting with or obstructing implementation of the 2017 Clean Air Plan would be less than significant with mitigation incorporated. Level of Significance Less than significant impact. Cumulative Criteria Pollutant Emissions Impact AIR-2: The proposed project could result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or State ambient air quality standard. Impact Analysis In developing thresholds of significance for criteria air pollutants, the BAAQMD considered the emission levels for which a project’s individual emissions would be cumulatively significant. As such, if a project exceeds the identified thresholds of significance, its emissions would be significant in terms of both project- and cumulative-level impacts, resulting in significant adverse air quality impacts to the region’s existing air quality conditions. Thus, this impact analysis and discussion is related to the project- and cumulative-level effect of the project’s regional criteria air pollutant emissions. The region is non-attainment for the federal and State ozone standards, the State PM10 standards, and the federal and State PM2.5 standards. Potential impacts would result in exceedances of State or federal standards for NOX or particulate matter (PM10 and PM2.5). NOX emissions are of concern because of potential health impacts from exposure to NOX emissions during both construction and operation and as a precursor in the formation of airborne ozone. PM10 and PM2.5 are of concern during construction, because of the potential to emit exhaust emissions from the operation of off-road construction equipment and fugitive dust during earth-disturbing activities (construction fugitive dust). ROG emissions are also important, because of their participation in the formation of airborne ozone. Ozone is a respiratory irritant and an oxidant that increases susceptibility to respiratory infections and that can cause substantial damage to vegetation and other materials. Elevated ozone concentrations result in reduced lung function, particularly during vigorous physical activity. This health problem is particularly acute in sensitive receptors such as the sick, elderly, and young children.

The non-attainment status of regional pollutants is a result of past and present development within the Air Basin, and this regional impact is a cumulative impact. In other words, new development projects (such as the proposed project) within the Air Basin would contribute to this impact only on a cumulative basis. No single project would be sufficient in size, by itself, to result in non-attainment of regional air quality standards. Instead, a project’s emissions may be individually limited, but cumulatively significant when taken in combination with past, present, and future development projects. The cumulative analysis focuses on whether a specific project would result in cumulatively significant emissions. According to Section 15064(h)(4) of the CEQA Guidelines, the existence of significant cumulative impacts caused by other projects alone does not constitute substantial evidence that the project’s incremental effects would be cumulatively significant. Rather, the determination of cumulative air quality impacts for construction and operational emissions is based on whether the proposed project would result in regional emissions that exceed the BAAQMD regional thresholds of significance for construction and operations on a project level. The thresholds of significance represent the allowable amount of emissions each project can generate without generating a cumulatively significant contribution to regional air quality impacts. Therefore, a project that would not exceed the BAAQMD thresholds of significance on the project level also would not be considered to result in a cumulatively significant impact with regard to regional air quality and would not be considered to result in a significant impact related to cumulative regional air quality. Construction Project construction activities, such as grading, excavation, and travel on unpaved surfaces would generate dust, can lead to elevated concentrations of PM10 and PM2.5. The operation of construction equipment results in exhaust emissions, which include ROG and NOX. Table 3.2-10 presents construction-period emissions that would result from implementation of the proposed project.

As indicated in Table 3.2-10, predicted construction-period emissions would not exceed the BAAQMD significance thresholds. Construction activities, particularly during site preparation and grading, would temporarily generate fugitive dust in the form of PM10 and PM2.5. Sources of fugitive dust would include disturbed soils at the construction site and trucks carrying uncovered loads of soils. Unless properly controlled, vehicles leaving the site would deposit mud on local streets, which could be an additional source of airborne dust after it dries. The BAAQMD CEQA Air Quality Guidelines consider these impacts to be less-than-significant if BMPs are implemented to reduce these emissions. MM AIR-2 would implement BAAQMD-recommended BMPs to reduce fugitive dust (PM10 and PM2.5). Operation Operational air emissions from the proposed project would be generated primarily from autos driven by future residents and guests. Evaporative emissions (e.g., ROG) from architectural coatings and maintenance products (classified as consumer products) are typical emissions from residential projects. The Air Quality and Greenhouse Gas Assessment 23 (Appendix B) prepared for the proposed project estimated long-term operational emissions associated with the proposed project using the CalEEMod emissions modeling program and the EMFAC2021 mobile source emission rate program. Table 3.2-11 shows average daily emissions of ROG, NOX, total PM10, and total PM2.5 during operation of the proposed project. The operational period emissions would not exceed the BAAQMD significance thresholds. For informational purposes, the emissions generated during the operation of prior Palmer School were estimated and included here. As shown in Table 3.2-11, emissions from the proposed project are anticipated to be less than the prior school use operation for all analyzed pollutants except ROG. 23 Illingworth & Rodkin, Inc. 2021.

Local Carbon Monoxide Impacts The CO emissions from traffic generated by the project are a concern at the local level. Congested intersections can result in high, localized concentrations of CO. The BAAQMD recommends a screening analysis to determine whether a project has the potential to contribute to a CO hotspot. The screening criteria identify when site-specific CO dispersion modeling is necessary. The proposed project would result in a less than significant impact to air quality for local CO if the following screening criteria are met: 1. The project is consistent with an applicable congestion management program established by the County Congestion Management Agency for designated roads or highways, regional transportation plan, and local congestion management agency plans. 2. The project traffic would not increase traffic volumes at affected intersections to more than 44,000 vehicles per hour. 3. The project traffic would not increase traffic volumes at affected intersections to more than 24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited (e.g., tunnel, parking garage, bridge underpass, natural or urban street canyon, below-grade roadway). As indicated in the Transportation Analysis prepared by Hexagon Transportation Consultants, Inc.,24 the studied intersection near the project site which currently experiences the greatest level of vehicle traffic is the intersection of Oak Road and Treat Boulevard, which experiences an estimated 24 Hexagon Transportation Consultants, Inc, 2021.

As discussed in the Transportation Analysis, the proposed project is estimated to generate a total of 93 AM peak-hour vehicle trips and 124 PM peak-hour vehicle trips. Conservatively assuming that all peak-hour vehicle trips generated by the proposed project would travel through the intersection of Oak Road and Treat Boulevard, the Existing Plus Project traffic volumes would be 6,109 AM peak- hour trips and 5,266 PM peak-hour trips. Therefore, the proposed project would not cause any intersections near the proposed project to experience traffic volumes of 44,000 vehicles per hour. Furthermore, the adjacent roadways are not located in an area where vertical or horizontal atmospheric mixing is substantially limited. Based on the above criteria, the proposed project would not cause an exceedance of the CO screening criteria and would have a less than significant impact related to CO. Level of Significance Before Mitigation Potentially significant impact.

Sensitive Receptors Exposure to Toxic Air Contaminant Concentrations Impact AIR-3: The proposed project could expose sensitive receptors to substantial pollutant concentrations. This impact addresses whether the proposed project would expose air pollution sensitive receptors to TACs such as construction-related asbestos during disturbance, construction-generated fugitive dust (PM10 and PM2.5), construction-related TACs, construction-generated DPM, operational-related TACs , or operational CO hotspots. The modeling assumptions and methodology for the construction health risk assessment are provided in Appendix B. As a residential project, the proposed project itself would be considered a sensitive receptor once operational. The project site is surrounded by existing residences to the south, east, and north of the project site. The closest off-site air pollution sensitive receptors in the vicinity of the project site include multi-family apartments north and south of the project site as well as single-family residences east of the project site across Oak Road. Construction Construction Asbestos Exposure Asbestos from Demolition Structures to be demolished sometimes contain asbestos-containing materials (ACM). Demolition of existing buildings and structures would be subject to BAAQMD Regulation 11, Rule 2 (Asbestos Contra Costa County—Oak Road Townhouse Condominiums Project Draft EIR Air Quality FirstCarbon Solutions 3.2-49 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx Demolition, Renovation, and Manufacturing). BAAQMD Regulation 11, Rule 2 is intended to limit asbestos emissions from demolition or renovation of structure and the associated disturbance of ACM generated or handled during these activities. The rule addresses the national emissions standards for asbestos along with some additional requirements. The rule requires the lead agency and its contractors to notify BAAQMD of any regulated renovation or demolition activity. This notification includes a description of structures and methods utilized to determine whether ACMs are potentially present. All ACM found on-site must be removed prior to demolition or renovation activity in accordance with BAAQMD Regulation 11, Rule 2, including specific requirements for surveying, notification, removal, and disposal of ACMs. Therefore, projects that comply with BAAQMD Regulation 11, Rule 2 would ensure that ACM would be removed and disposed of appropriately and safely. By complying with BAAQMD Regulation 11, Rule 2, thereby minimizing the release of airborne asbestos emissions, demolition activity would not result in a significant impact to air quality. Naturally Occurring Asbestos The USGS published a guide for generally identifying areas that are likely to contain naturally occurring asbestos. The associated USGS map indicates that there are several locations within the County that are likely to contain naturally occurring asbestos; however, none of these sites are located within a 1-mile vicinity of the project site.25 Therefore, it can be reasonably concluded that the proposed project would not expose sensitive receptors to naturally occurring asbestos during project construction. This impact would be less than significant. Construction Fugitive Dust Activities associated with earthmoving activities and construction would generate short-term emissions of fugitive dust resulting in increased dust fall and locally elevated levels of PM10 and PM2.5 downwind of construction activity. Construction dust has the potential for creating a nuisance at nearby properties. As addressed under Impact AIR-2, MM AIR-2 is included to ensure that the BAAQMD BMPs would be implemented to reduce fugitive dust emissions from construction activities to less than significant. Implementation of MM AIR-2 would ensure impacts related to generation of localized fugitive dust during construction of the proposed project would be less than significant with mitigation. Project-specific Construction TACs A Health Risk Assessment (HRA) is a guide that helps to determine whether current or future exposures to a chemical or substance in the environment could affect the health of a population. In general, risk depends on the following factors: • Identify the TACs that may be present in the air. • Estimate the amount of TACs released from all sources, or the source of particular concern, using air samples or emission models. 25 United States Geological Survey. 2011. Reported Historic Asbestos Mines, Historic Asbestos Prospects, and Other Natural Occurrences of Asbestos in California. Website: https://pubs.usgs.gov/of/2011/1188/. Accessed June 21, 2021.

During construction, the proposed project would result in the emissions of TACs that could potentially impact nearby sensitive receptors. TACs are the air pollutants of most concern as it relates to sensitive receptors, as they have the greatest potential to pose a carcinogenic and non- carcinogenic (such as asthma and bronchitis) hazard to human health. The BAAQMD has defined health risk significance thresholds, as previously discussed. These thresholds are represented as a cancer risk to the public and a non-cancer hazard from exposures to TACs. Cancer risk represents the probability (in terms of risk per million individuals) that an individual would contract cancer resulting from exposure to TACs continuously over a period of several years. Construction DPM Emissions The DPM construction emissions (as PM2.5 exhaust emissions) were estimated using CalEEMod Version 2016.3.2. On-site DPM emissions would be generated by off-road construction equipment and the off-site DPM emissions would be generated by trips associated with the hauling of material, vendor trips, and worker vehicle traffic. Air Dispersion Modeling Results The EPA AERMOD air dispersion model was used to predict DPM and PM2.5 concentrations at sensitive receptors (i.e., residents) in the vicinity of the proposed project site. As presented in the memo prepared by Illingworth & Rodkin, Inc. (see Appendix B), the highest concentration of construction-related DPM and fugitive PM2.5, and thus the maximally exposed individual (MEI), was located at a multi-family residence adjacent to the northern project boundary. As shown in Table 3.2-12, the unmitigated incremental increase in cancer risk from construction was 16.3 per million at the MEI. The maximum annual PM2.5 concentration from construction was 0.45 µg/m3. Both exceed their respective BAAQMD single-source thresholds of greater than 10 in a million and greater than 0.3 µg/m3 for PM2.5 concentration. Therefore, as discussed below, MM AIR-3 would be required to reduce the generation of DPM during project construction to reduce health risk impacts to less than significant.

Table 3.2-12 summarizes the incremental cancer risk, PM2.5 concentrations, and health hazard indexes at the MEI during project construction. With the incorporation of MMs AIR-2 and AIR-3, the incremental cancer risk and PM2.5 concentration would not exceed the appropriate BAAQMD’s single-source thresholds. Both the unmitigated and mitigated non-cancer hazards from construction activities would be below the BAAQMD’s single-source significance threshold of 1.0. Community Health Risk Assessment Table 3.2-13 displays the cumulative community risk impacts at the sensitive receptors most affected during project construction (i.e., the construction MEI and receptor with the highest annual construction-related PM2.5 concentration). The cumulative community health risks shown in Table 3.2-13 consider existing DPM emissions from Interstate 680, a nearby truck weigh station, Oak Road, Treat Boulevard, and six nearby facilities hosting permitted stationary source equipment. As shown in Table 3.2-13, the incorporation of MM AIR-3 would not reduce the annual PM2.5 concentration to below the BAAQMD’s community threshold of 0.8 µg/m3, ultimately resulting in a community annual PM2.5 concentration of 1.17 µg/m3. Nonetheless, as shown in Table 3.2-12, the proposed project’s contribution to that exceedance in community annual PM2.5 concentration constitutes an estimated 0.19 µg/m3. As such, without implementation of the proposed project, the area would otherwise experience an annual PM2.5 concentration of 0.98 µg/m3, which is currently above the BAAQMD’s threshold of 0.8 µg/m3. Therefore, because the proposed project would be implementing mitigation sufficient to reduce the proposed project’s health risk impacts to below the BAAQMD’s single-source thresholds and the annual PM2.5 concentration would exceed BAAQMD thresholds without implementation of the proposed project, the proposed project would not be cumulatively considerable or result in a significant impact.

Carbon Monoxide Hotspot As discussed in Impact AIR-1, the proposed project would not generate sufficient CO emissions during project operation to substantiate the creation of a CO hotspot. Therefore, this impact would be less than significant with regard to exposing sensitive receptors to substantial concentrations of CO emissions. As such, the proposed project would result in less-than-significant impacts related to exposing sensitive receptors to substantial pollutant concentrations. Level of Significance Potentially significant impact. Mitigation Measures MM AIR-3 Selection of equipment during construction to minimize diesel particulate matter (DPM) emissions. The project shall implement the following: 1. Prior to the issuance of grading or construction permits, the applicant shall provide the Department of Conservation and Development, Community Development Division (CDD) with documentation to the satisfaction of CDD that all diesel-powered off-road equipment, larger than 25 horsepower, operating on the site for more than two days continuously, at a minimum, meet United States Environmental Protection Agency (EPA ) emissions standards for Tier 4 Interim engines. Where Tier 4 equipment is not available, exceptions could be made for equipment meeting Tier 2 or Tier 3 standards that include California Air Resources Board (ARB)-certified Level 3 Diesel Particulate Filters or equivalent. Equipment that is electrically powered or uses non-diesel fuels would also meet this requirement. 2. Minimize diesel generator use by providing line power to the site during early construction phases. 3. Avoid staging construction equipment near residences (i.e., within 200 feet of homes). Level of Significance After Mitigation Less than significant impact.

Impact Analysis Construction During construction activities, construction equipment exhaust and application of asphalt and architectural coatings would temporarily generate odors. Any construction-related odor emissions would be temporary and intermittent. Additionally, noxious odors would be confined to the immediate vicinity of the construction equipment. It is anticipated that by the time such emissions reach any sensitive receptor sites, they would be diluted to well below any level of air quality or odor concern. Therefore, construction odor impacts would be less than significant. Operation The proposed project would consist of a new multi-family residential development. Operation of this type of project would likely not generate objectionable odors. The type of uses that are considered to have objectionable odors include wastewater treatments plants, compost facilities, landfills, solid waste transfer stations, fiberglass manufacturing facilities, paint/coating operations (e.g., auto body shops), dairy farms, petroleum refineries, asphalt batch plants, chemical manufacturing, and food manufacturing facilities. Four such facilities, operated by East Bay Municipal Utility District, were identified within the 1- and 2-mile odor screening distances for wastewater and pumping facilities. Nonetheless, public records retrieved from the BAAQMD show that no odor complaints were filed for these locations between January 1, 2018, and the time at which this analysis was prepared. Moreover, as the proposed project is residential in nature, it is not anticipated to generate objectionable odors which may affect a substantial number of people. Therefore, this impact would be less than significant. Level of Significance Less than significant impact. 3.2.5 - Cumulative Impacts The BAAQMD considers the emission levels for which a project’s individual emissions would be cumulatively significant. As such, if a project exceeds the identified thresholds of significance, its emissions would be significant in terms of both project- and cumulative-level impacts, resulting in significant adverse air quality impacts to the region’s existing air quality conditions. As stated in the BAAQMD 2017 CEQA Guidelines, additional analysis to assess cumulative impacts is unnecessary. Rather, the determination of cumulative air quality impacts for construction and operational emissions is based on whether the proposed project would result in regional emissions that exceed BAAQMD regional thresholds of significance for construction and operations on a project level. Projects that generate emissions below the BAAQMD significance thresholds would be considered consistent with regional air quality planning efforts would not generate cumulatively significant emissions. As discussed in Impact AIR-2, with the incorporation of MM AIR-2, the proposed project would result in construction and operational emissions which are less than the respective BAAQMD significance thresholds and would therefore not have a cumulatively considerable contribution to a Contra Costa County—Oak Road Townhouse Condominiums Project Air Quality Draft EIR 3.2-54 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-02 Air Quality.docx cumulative impact. The proposed project would therefore result in less than significant cumulative air quality impacts. Regarding impacts to sensitive receptors, the DPM emissions from construction of the proposed project would result in less than significant health impacts after implementation of MM AIR-3 and would not combine with emissions from other cumulative projects to the extent that a significant cumulative impact would occur. In addition, the operational DPM emissions during operation of the proposed project would not result in significant health impacts and would constitute the greatest level of development. Given that the proposed project would be required to implement mitigation that is likely to result in decreased DPM emissions from what is disclosed in this analysis, the combined operation of the proposed project would not result in exposing nearby sensitive receptors to substantial amounts of pollutants. As discussed in Chapter 3, Environmental Impact Analysis, foreseeable future development projects in the area would not place new sensitive receptors near the proposed project that would be exposed to substantial amounts of pollutants. Therefore, the cumulative impact associated with construction and operation of the proposed project would be less than significant. Odor impacts that would be associated with the proposed project would principally be limited to the combustion of transportation fuels during construction and operation. The impact would be less than significant during project construction and operation would be intermittent and spatially dispersed. Therefore, cumulative odor impacts would be less than significant. The proposed project would not result in significant cumulative air quality or health impacts. Level of Cumulative Significance Before Mitigation Potentially significant impacts. Cumulative Mitigation Measures Implement MM AIR-2 and MM AIR-3. Level of Cumulative Significance After Mitigation Less than significant impact.

This section also evaluates the possible impacts related to biological resources that could result from implementation of the proposed project and includes appropriate mitigation measures to reduce potential impacts to a less than significant level. Information in this section is based on a special-status species assessment and subsequent supplemental documentation prepared by Live Oak Associates on December 2, 2020, and May 12, 2021, respectively; a Tree Report prepared by HortScience/Bartlett Consulting on January 11, 2021; and a brief memorandum prepared by FirstCarbon Solutions (FCS) as part of the peer review process to confirm existing conditions on the project site as outlined by Live Oak and HortScience/Bartlett Consulting. These reports can be found in Appendix C. During the Notice of Preparation (NOP) comment period, the following comments were received related to the proposed project regarding Biological Resources: • Objection to the removal of 74 trees including many valley oak trees and its potential impact on animal and avian species, as well as on views; stating that the neighboring residents have cooperated with project site owners to pay for maintenance of tree No. 80; requesting that tree No. 77, 78, and 79 be preserved in addition to tree No. 80. • Concern that the proposed tree removal would put plant and animal species at risk. • Objection to the removal of 75 of the 81 [sic] trees on the project site, including seven heritage valley oaks; stating that the City of Walnut Creek required the developer of the Tiffany site to build around a heritage tree originally planned for removal and urging the County to do the same with trees on the proposed site; questioning the necessity to remove 24 healthy mature coast redwoods on the southern border of the project site only to replace them at a later date and suggesting they be preserved. • Concerns regarding impacts to biological resources, stating a complete environmental impact report should be completed. • Concerns regarding biological impacts due to change from previous agricultural uses. • Requesting preservation of the oak tree that faces a specific unit. 3.3.2 - Environmental Setting Records Searches and Field Survey to Identify Existing Biological Resources Literature Review FCS Biologists reviewed existing environmental documentation for the project site and immediate vicinity. This documentation included the special-status species assessment and subsequent supplemental documentation prepared by Live Oak Associates and a Tree Report prepared by HortScience/Bartlett Consulting. Additionally, relevant literature pertaining to the habitat Contra Costa County–Oak Road Townhouse Condominiums Project Biological Resources Draft EIR 3.3-2 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx requirements of special-status species potentially occurring near the project site; and species data provided by the United States Fish and Wildlife Service (USFWS) and the California Department of Fish and Wildlife (CDFW) was queried. Topography and Hydrology FCS Biologists reviewed current United States Geological Survey (USGS) 7.5-minute topographic quadrangle map(s) and aerial photographs as a preliminary analysis of the existing conditions within the project site and immediate vicinity. Information obtained from the review of the topographic maps included elevation range, general watershed information, and potential drainage feature locations.1 Aerial photographs provide a perspective of the most current site conditions relative to on-site and off-site land use, plant community locations, and potential locations of wildlife movement corridors. Soil FCS Biologists also reviewed United States Department of Agriculture (USDA) soil surveys to establish if soil conditions on the project site are suitable for special-status plant species.2 These soil profiles include soil series with similar thickness, arrangement, and other important characteristics. The soil series consist of separate soil mapping units that provide specific information regarding soil characteristics. Many special-status plant species and habitat types have a limited distribution based exclusively on soil type. Therefore, pertinent USDA soil survey maps were reviewed to determine the existing soil mapping units within the project site and to establish if soil conditions are suitable for any special-status plant species. Special-status Wildlife and Plant Species FCS Biologists compiled a list of threatened, endangered, and otherwise special-status species previously recorded within a 5-miles radius of the project site. The list was based on Live Oak’s special- status species assessment and subsequent supplemental documentation, search of the CDFW California Natural Diversity Database (CNDDB),3 a special-status species and plant community account database, and the California Native Plant Society (CNPS) Electronic Inventory (CNPSEI) of Rare and Endangered Vascular Plants of California database 4 for the Walnut Creek, California USGS 7.5-minute Topographic Quadrangle Map and eight surrounding quadrangles (Benicia, Vine Hill, Honker Bay, Briones Valley, Clayton, Oakland East, Las Trampas Ridge, and Diablo). The database search results can be found in Appendix C. The CNDDB Biogeographic Information and Observation System (BIOS) database 5 was used to determine the distance between known recorded occurrences of special-status species and the project site. 1 United States Geological Survey (USGS). 2021 USGS Maps.

The FCS Biologist made notations regarding suitable habitat for those special-status species determined to potentially occur within the project site.11 Online resources such as eBird were consulted, as necessary. 12 Trees FCS Biologists reviewed applicable County ordinances pertaining to tree preservation and protective measures and their tree replacement conditions or permits required, such as Section 816-6.8010 of the Contra Costa County Code. FCS also performed a peer review of the previously completed Tree Report (Appendix C).13 Jurisdictional Waters and Wetlands Prior to conducting the field survey, an FCS Biologist reviewed USGS topographic maps and aerial photography to identify any potential natural drainage features and water bodies. In general, all surface drainage features identified as blue-line streams on USGS maps and associated riparian habitat are considered potentially subject to State and federal regulatory authority as “waters of the United States and/or State.” A preliminary assessment was conducted to determine the location of any existing drainages and limits of project-related grading activities, to aid in determining whether any waters of the United States or State was present on-site. Field Survey FCS Biologist, Robert Carroll conducted a reconnaissance-level field survey of the project site on April 27, 2021, between approximately 10:30 a.m. and 11:30 a.m. The object of the survey was to ascertain general site conditions and identify potential suitable habitat for various special-status plant and wildlife species, and the potential or actual presence of other sensitive biological resources. These areas included on-site trees and structures that have the potential to support 6 Jepson Flora Project (eds.) 2021. Jepson eFlora, https://ucjeps.berkeley.edu/eflora/.

Special-status species with potential to occur on the project site identified during the literature review were a focus during the reconnaissance-level survey. Project Site–Urban/Developed The general vicinity of the project site is dominated by a cover of suburban landscapes, which mostly support ornamental landscaping. The project site is developed and consists of eight parcels, and is located southeast of the intersection of Interstate 680 (I-680) and Treat Boulevard, within unincorporated Contra Costa County. The former Palmer School for Boys and Girls, a private elementary school, operated at the project site from 1939 until its closure due to COVID-19 in June 2020. The project site is within a developed urban area and surrounded by residential and commercial development. The project site contains vacant and occupied associated structures, two grass fields, parking lots, and planters. The 5.94-acre project site is composed of 5.92-acres of hardscaped areas and .02-acre of grass fields located on the western and eastern edges of the project site, which appeared to be highly managed (regularly mowed), and in case of the sports field, irrigated. The project site contains 81 trees, representing 21 species. Trees are clustered in the northern, eastern, and southern portions of the site. The most abundant species on-site include 27 coast redwoods (Sequoia sempervirens), nine valley oaks (Quercus lobata), and eight glossy privets (Ligustrum japonicum). No other species is represented by more than five trees. Sensitive Biological Communities Sensitive biological communities are considered to include vegetation communities listed in the CNDDB and communities listed by the CDFW Natural Communities List with a rarity ranked between S1-S3. Aquatic habitats, including wetlands, and riparian corridors are also typically considered sensitive natural communities and are addressed in the environmental review process, if present. A sensitive biological community first must be naturally occurring to be classified as such. Aerial photography indicates that most of the trees on-site appear to be ornamental plantings and thus not part of a natural community (e.g., naturally occurring oak savanna or oak woodland).14 While there are no sensitive biological communities located on the project site, individual trees are protected and discussed in further detail in Impact BIO-5 below. Wetlands and Waters of the United States and the State Wetlands and waters of the United States and waters of the State are protected as aquatic resources that provide habitat for common and special-status species. Types of aquatic resource features include open water, tidal marsh, seasonal wetland, wetlands swale, streams, creeks and other waters. 14 Google Earth Pro, 1937. 37° 55' 27.33"N, 122° 03' 31.52"W, Eye alt 3,281 ft.

The project site is built out and lacks aquatic features such as streams, creeks, ponds, and vernal pools. Common Species The vegetation community and land cover type discussed above provide habitat for numerous local wildlife species. The project site may provide cover and foraging opportunities for urban-adapted mammals such as raccoon (Procyon lotor) and Virginia opossum (Didelphis virginiana). Because of a lack of suitable habitat, it is unlikely that amphibians and reptiles would regularly occur on the project site. The trees within the project site and within the greater project site vicinity provide suitable habitat for nesting avian species. The small number of wildlife species observed on or near the project site consist of avian species identified by song or sight. The following species were observed during the April 2021 field survey: Anna’s h ummingbird (Calypte anna), rock pigeon (Columba livia), American crow (Corvus brachyrhynchos) mourning dove (Zenaida macroura), California scrub jay (Aphelocoma californica), and house finch (Haemorhous mexicanus). Special-status Species Special-status species, whether plants, wildlife, or fish, are considered sufficiently rare that they require special consideration and/or protection and have been or should be listed as rare, threatened, or endangered by the federal and/or State governments. Special-status species are defined as meeting one or more of the following criteria: • Listed or proposed for listing under the California Endangered Species Act (CESA) and the federal Endangered Species Act; • Protected by the Migratory Bird Treaty Act (MBTA ); • CDFW Fully Protected Species and Species of Special Concern; or • Plant species on the CNPS List ranked as 1, 2, or 3. The following discussion focuses on potential for occurrence of special-status species on the project site. Special-status Plant Species Evaluated The Special-status Plant Species Table (Appendix C, Table 1) lists 20 special-status plant species and CNPS sensitive species that have been recorded within a 5-mile radius of the project site (Exhibit 3.3-1).15,16,17 The table also includes the species’ status, required habitat, and potential to occur within the project site. Special-status plant species that were determined to have no potential to occur on-site are also included in the table, along with the justification for their exclusion from 15 California Department of Fish and Wildlife (CDFW). 2021.

A plant’s potential to occur on the project site was based on presence of suitable habitats, soil types, and occurrences recorded by the CNPSEI and CNDDB within the Walnut Creek, California Topographic Quadrangle Map and eight surrounding quadrangles. None of the species evaluated shown in Table 1 has the potential to occur within the project site because no native natural habitat that could support native special-status plant species occurs within the project site. Based upon the literature review and field surveys conducted by both Live Oak and FCS, and professional experience, no special-status plant species are expected to occur within the project site because of the absence of suitable habitat, previous land use, and the urban/developed land cover. Special-status Wildlife Species Evaluated The Special-status Wildlife Species Table (Appendix C, Table 2) identifies 28 federally and State-listed threatened and/or endangered wildlife species and California Species of Special Concern that were analyzed by Live Oak and have been recorded within a 5-mile radius of the project site (Exhibit 3.3- 1).18,19 Table 2 includes the species’ status, required habitat types and features, and potential to occur within the project site. Additionally, Table 2 includes all special-status wildlife species that have been determined unlikely to occur on-site, primarily based on the absence of suitable habitat and the lack of recorded occurrence in the project vicinity, along with the justification for their exclusion from further discussion. The potential for wildlife to occur on the project site was based on presence of suitable habitats and occurrences recorded by the CNDDB within the Walnut Creek, California Topographic Quadrangle Map and eight surrounding quadrangles. Twenty-three of the 28 special-status wildlife species recorded were determined to have no potential to occur and are therefore excluded from further analysis. Five special-status wildlife species have at least some potential to occur on the project site and are therefore discussed in further detail below. Mammals Pallid Bat Pallid bat (Antrozous pallidus) is a California Species of Special Concern. This species occurs commonly in low elevations throughout California and occupies a wide variety of habitats, including woodlands, grasslands, shrublands, and forests from sea level up to mixed conifer forests. There have been 11 recorded occurrences of this species within the Walnut Creek, California Topographic Quadrangle Map and eight surrounding quadrangles.20 This species is most common in open, dry habitats with rocky areas, but may also be found in caves, crevices, hollow trees, and buildings for roosting. The project site generally lacks suitable foraging habitat for this species and the nearest recorded occurrence is approximately 1.25 miles from the project site. However, the trees and buildings present within the project site and within the immediate vicinity may provide marginal roosting habitat for this species. 18 California Department of Fish and Wildlife (CDFW). 2021.

This species is found throughout California, but details regarding its distribution are not well known. This species is found in all but alpine and sub-alpine habitats. It is most common in mesic habitats where it gleans from trees or feeds along habitat edges. This species requires caves, tunnels, buildings, or other anthropogenic structures for roosting. There have been four recorded occurrences of this species within the Walnut Creek, California Topographic Quadrangle Map and eight surrounding quadrangles.21 The project site generally lacks suitable foraging habitat for this species and the nearest recorded occurrence is approximately 1.25 miles from the project site. However, the trees and buildings present within the project site and within the immediate vicinity may provide marginal roosting habitat for this species. Hoary Bat Hoary bat (Lasiurus cinereus) is listed by the Western Bat Working Group as “medium priority.” This species prefers open habitats or habitat mosaics, with access to trees for cover and open areas for feeding. Roosts are in dense foliage of medium to large trees. There have been four recorded occurrences of this species within the Walnut Creek, California Topographic Quadrangle Map and eight surrounding quadrangles.22 The project site generally lacks suitable foraging habitat for this species and the nearest recorded occurrence is approximately 2 miles from the project site. However, the trees and buildings present within the project site and within the immediate vicinity may provide marginal roosting habitat for this species. Big Free-tailed Bat Big free-tailed bat (Nyctinomops macrotis) is a California Species of Special Concern. This species mainly inhabits rugged and rocky terrain and roosts in buildings caves, and occasionally in holes in trees. This species was analyzed by Live Oak but was not recorded within 5 miles of the project site. The nearest recorded occurrence is approximately 7.5 miles north of the project site.23 While the project site lacks rocky terrain, it does contain buildings that may provide marginal roosting habitat for this species. Migratory and Nesting Birds Trees within the project site provide suitable nesting habitat for various avian species, including special-status species such as white-tailed kite (Elanus leucurus) as well as birds protected under the MBTA and the California Fish and Game Code. White-tailed Kite White-tailed kite is listed as a Fully Protected species by the CDFW. This species generally inhabits rolling foothill and valley margins with scattered oaks. It is also found in open grasslands, meadows, and agricultural areas. This species was analyzed by Live Oak but was not recorded within 5 miles of the project site. 21 California Department of Fish and Wildlife (CDFW). 2021.

Wildlife Movement Corridors An FCS Biologist evaluated the project site for evidence of a wildlife movement corridor during the field survey, concluding that the project site is not part of or within a wildlife movement corridor. The lack of aquatic features on or in the project vicinity prevent wildlife movement corridors for fish or other aquatic dependent species. Additionally, the high level of development on or in the project vicinity combined with various barriers, including I-680 directly to the west, further impede the movement of terrestrial species through the area. Regulated Trees Trees are protected under Chapter 816-6 of the Ordinance Code. Trees having a diameter of 6.5 inches or greater as measured 4.5 feet from ground level is considered a protected tree under the County’s Code Section 816-6.6004. According to the Tree Report, all trees over 6 inches in diameter located within the proposed project limits were assessed. 81 trees were assessed representing 22 species. Of the 81 trees assessed (including 75 on-site), six (tree No. 80, 160, 161, 168, 171, and 172) appeared to be located on adjacent properties. These six trees were included in the assessment because their trunks were within 2 feet of the presumed property line and/or tree crowns extended into the project area. Seventy-three of the 81 trees inventoried qualify as “protected” trees due to their size; therefo re, removal of these trees would require permits (Exhibit 3.3-2). 3.3.3 - Regulatory Framework Federal Endangered Species Act The United States Congress passed the Endangered Species Act in 1973 to protect those species that are endangered or threatened with extinction. The Endangered Species Act is intended to operate in conjunction with the National Environmental Policy Act (NEPA) to help protect the ecosystems upon which endangered and threatened species depend. The Endangered Species Act prohibits the “take” of endangered or threatened wildlife species. “Take” is defined to include harassing, harming, pursuing, hunting, shooting, wounding, killing, trapping, capturing, or collecting wildlife species or any attempt to engage in such conduct (16 United States Code [USC] § 1531 et seq.). “Harm” is further defined to include significant habitat modification or degradation that results in death or injury to listed species by significantly impairing behavioral patterns (50 Code of Federal Regulations [CFR] § 17.3). “Harass” is defined as actions that create the likelihood of injury to listed species to such an extent as to significantly disrupt normal behavior patterns (50 CFR § 17.3). Actions that result in take can result in civil or criminal penalties. The Endangered Species Act and the Clean Water Act (CWA) Section 404 guidelines prohibit the issuance of wetland permits for projects that jeopardize the continued existence of any endangered 24 California Department of Fish and Wildlife (CDFW). 2021.

The United States Army Corps of Engineers (USACE) must consult with the USFWS and/or the National Marine Fisheries Service (NOAA Fisheries) when threatened or endangered species under their jurisdiction may be affected by a proposed project. In the context of the proposed project, Endangered Species Act consultation would be initiated if development resulted in take of a threatened or endangered species or if issuance of a Section 404 permit or other federal agency action could result in take of an endangered species or adversely modify critical habitat of such a species. Migratory Bird Treaty Act Raptors (birds of prey), migratory birds, and other avian species are protected by several State and federal laws. The MBTA prohibits the killing, possessing, or trading of migratory birds except in accordance with regulations prescribed by the Secretary of the Interior. Eagle Protection Act The golden eagle (Aquila chrysaetos) and bald eagle (Haliaeetus leucocephalus) are afforded additional protection under the Eagle Protection Act, amended in 1973 (16 United States Code [USC] § 669, et seq.) and the Bald and Golden Eagle Protection Act (16 USC §668–668d). Clean Water Act The USACE regulates the discharge of dredge or fill material into waters of the United States under Section 404 of the CWA. “Discharges of fill material” is defined as the addition of fill material into waters of the United States, including, but not limited to, the following: placement of fill that is necessary for the construction of any structure or impoundment requiring rock, sand, dirt, or other material for its construction; site-development fills for recreational, industrial, commercial, residential, and other uses; causeways or road fills; fill for intake and outfall pipes and subaqueous utility lines (33 CFR § 328.2(f)) In addition, Section 401 of the CWA (33 United States Code [USC] 1341) requires any applicant for a federal license or permit to conduct any activity that may result in a discharge of a pollutant into waters of the United States to obtain a certification that the discharge will comply with the applicable effluent limitations and water quality standards. Waters of the United States include a range of wet environments such as lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, and wet meadows. Boundaries between jurisdictional waters and uplands are determined in a variety of ways, depending on which type of waters is present. Methods for delineating wetlands and non-tidal waters are described below. • Wetlands are defined as “those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions” (33 CFR § 328.3(b)) Presently, to be a wetland, a site must exhibit three wetland criteria: hydrophytic vegetation, hydric soils, and wetland hydrology existing under the “normal circumstances” for the site. • The lateral extent of non-tidal waters is determined by delineating the ordinary high water mark (OHWM) (33 CFR § 328.4(c)(1)). The OHWM is defined by the USACE as “that line on Contra Costa County–Oak Road Townhouse Condominiums Project Biological Resources Draft EIR 3.3-10 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx shore established by the fluctuations of water and indicated by physical character of the soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas” (33 CFR § 328.3(e)). Navigable Waters Protection Rule On April 21, 2020, the United States Environmental Protection Agency (EPA) and the USACE (collectively “Agencies”) published a new definition of waters of the United States in the Federal Register. This new definition, called the 2020 Navigable Waters Protection Rule (NWPR), went into effect on June 22, 2020. Under the 2020 NWPR, the Code of Federal Regulations (33 CFR § 328.3(a); 40 CFR § 230.3(s)) currently defines waters of the United States as: 1. The territorial seas, and traditional navigable waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including waters which are subject to the ebb and flow of the tide; 2. Perennial and intermittent tributaries that contribute surface water flow to such waters; 3. Certain ponds, lakes, and impoundments of jurisdictional waters; and 4. Adjacent wetlands to other jurisdictional features. Section 404 jurisdiction regarding “other waters” refers to features such as ponds, lakes, and streams, extends to the upward limit of the OHWM. The OHWM is defined as the “line on shore established by the fluctuations of water and indicated by physical characteristics such as a clear natural line impressed on the bank; shelving; changes in the character of soil; destruction of terrestrial vegetation; the presence of litter or debris; or other appropriate means that consider the characteristics of the surrounding areas.” (33 CFR Section 328.3(7)). State California Endangered Species Act The State of California enacted CESA in 1984. CESA pertains to State-listed endangered and threatened species. CESA requires State agencies to consult with the CDFW when preparing California Environmental Quality Act (CEQA) documents. The purpose is to ensure that the State lead agency actions do not jeopardize the continued existence of a listed species or result in the destruction or adverse modification of habitat essential to the continued existence of those species if there are reasonable and prudent alternatives available (California Fish and Game Code [FGC] § 2080). CESA directs agencies to consult with the CDFW on projects or actions that could affect listed species, directs CDFW to determine whether jeopardy would occur, and allows the CDFW to identify “reasonable and prudent alternatives” to the project consistent with conserving the species. CESA allows the CDFW to authorize exceptions to the State’s prohibition against take of a listed species if the “take” of a listed species is incidental to carrying out an otherwise lawful project that has been approved under CEQA (FGC § 2081). Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Biological Resources FirstCarbon Solutions 3.3-11 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx California Fish and Game Code Under CESA, the CDFW has the responsibility for maintaining a list of endangered and threatened species (FGC § 2070). Fish and Game Code Sections 2050 through 2098 outline the protection provided to California’s rare, endangered, and threatened species. Fish and Game Code Section 2080 prohibits the taking of plants and animals listed under the CESA. Fish and Game Code Section 2081 established an incidental take permit program for State-listed species. The CDFW maintains a list of “candidate species,” which it formally notices as being under review for addition to the list of endangered or threatened species. In addition, the Native Plant Protection Act of 1977 (NPPA) (FGC § 1900, et seq.) prohibits the taking, possessing, or sale within the State of any plants with a State designation of rare, threatened, or endangered (as defined by the CDFW). An exception to this prohibition in the NPPA allows landowners, under specified circumstances, to take listed plant species, provided that the owners first notify CDFW and give the agency at least 10 days to come and retrieve (and presumably replant) the plants before they are plowed under or otherwise destroyed. Fish and Game Code Section 1913 exempts from “take” prohibition “the removal of endangered or rare native plants from a canal, lateral ditch, building site, or road, or other right of way.” Project impacts to these species are not considered significant unless the species are known to have a high potential to occur within the area of disturbance associated with construction of the proposed project. The CDFW also maintains lists of “Species of Special Concern” that serve as species “watch lists.” The CDFW has identified many Species of Special Concern. Species with this status have limited distribution or the extent of their habitats has been reduced substantially, such that their populations may be threatened. Thus, their populations are monitored, and they may receive special attention during environmental review. While they do not have statutory protection, they may be considered rare under CEQA and thereby warrant specific protection measures. Sensitive species that would qualify for listing but are not currently listed are afforded protection under CEQA. CEQA Guidelines Section 15065 (Mandatory Findings of Significance) requires that a substantial reduction in numbers of a rare or endangered species be considered a significant effect. CEQA Guidelines Section 15380 (Rare or Endangered Species) provides for the assessment of unlisted species as rare or endangered under CEQA if the species can be shown to meet the criteria for listing. Unlisted plant species on the CNPS List ranked 1A, 1B, and 2 would typically require evaluation under CEQA. Fish and Game Code Sections 3500 to 5500 outline protection for fully protected species of mammals, birds, reptiles, amphibians, and fish. Species that are fully protected by these sections may not be taken or possessed at any time. The CDFW cannot issue permits or licenses that authorize the take of any fully protected species, except under certain circumstances such as scientific research and live capture and relocation of such species pursuant to a permit for the protection of livestock. Under Fish and Game Code Section 3503.5, it is unlawful to take, possess, or destroy any birds in the orders of Falconiformes or Strigiformes (birds of prey) or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided by this code or any regulation adopted pursuant Contra Costa County–Oak Road Townhouse Condominiums Project Biological Resources Draft EIR 3.3-12 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx thereto. To comply with the requirements of CESA, an agency reviewing a proposed project within its jurisdiction must determine whether any State-listed endangered or threatened species may be present in the project study area and determine whether the proposed project will have a potentially significant impact on such species. In addition, the CDFW encourages informal consultation on any proposed project that may impact a candidate species. Project-related impacts to species on the CESA endangered or threatened list would be considered significant. State-listed species are fully protected under the mandates of CESA. “Take” of protected species incidental to otherwise lawful management activities may be authorized under Fish and Game Code Section 206.591. Authorization from the CDFW would be in the form of an Incidental Take Permit. Fish and Game Code Section 1602 requires any entity to notify the CDFW before beginning any activity that “may substantially divert or obstruct the natural flow of, or substantially change or use any material from the bed, channel, or bank of any river, stream, or lake” or “deposit debris, waste, or other materials that could pass into any river, stream, or lake.” “River, stream, or lake” includes waters that are episodic and perennial; and ephemeral streams, desert washes, and watercourses with a subsurface flow. A Lake or Streambed Alteration Agreement will be required if the CDFW determines that project activities may substantially adversely affect fish or wildlife resources through alterations to a covered body of water. California Department of Fish and Wildlife Species of Concern In addition to formal listing under the Endangered Species Act and CESA, species receive additional consideration by the CDFW and local lead agencies during the CEQA process. Species that may be considered for review are included on a list of “Species of Special Concern,” developed by the CDFW. It tracks species in California whose numbers, reproductive success, or habitat may be threatened. In addition to Species of Special Concern, the CDFW identifies animals that are tracked by the CNDDB but warrant no federal interest and no legal protection. These species are identified as California Special Animals. Porter-Cologne Water Quality Control Act The CDFW is a trustee agency that has jurisdiction under Fish and Game Code Section 1600, et seq. Under Fish and Game Codes Sections 1602 and 1603, a private party must notify the CDFW if a proposed project would “substantially divert or obstruct the natural flow or substantially change the bed, channel, or bank of any river, stream, or lake designated by the department, or use any material from the streambeds . . . except when the department has been notified pursuant to Section 1601.” Additionally, the CDFW may assert jurisdiction over native riparian habitat adjacent to aquatic features, including native trees over 4 inches in diameter at breast height (DBH). If an existing fish or wildlife resource may be substantially adversely affected by the activity, the CDFW may propose reasonable measures that will allow protection of those resources. If these measures are agreeable to the parties involved, they may enter into an agreement with the CDFW identifying the approved activities and associated mitigation measures. Section 13260(a) of the Porter-Cologne Water Quality Control Act (contained in the California Water Code) requires any person discharging waste or proposing to discharge waste, other than to a Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Biological Resources FirstCarbon Solutions 3.3-13 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx community sewer system, within any region that could affect the quality of the waters of the State (all surface and subsurface waters) to file a report of waste discharge. The discharge of dredged or fill material may constitute a discharge of waste that could affect the quality of waters of the State. Historically, California relied on its authority under Section 401 of the CWA to regulate discharges of dredged or fill material to California waters. That section requires an applicant to obtain “water quality certification” from the California State Water Resources Control Board (State Water Board) through its Regional Water Quality Control Boards (RWQCBs) to ensure compliance with State water quality standards before certain federal licenses or permits may be issued. The permits subject to Section 401 include permits for the discharge of dredged or fill material (CWA Section 404 permits) issued by the USACE. Waste discharge requirements under the Porter-Cologne Water Quality Control Act were typically waived for projects that required certification. With recent changes that limited jurisdiction of wetlands under the CWA, the State Water Board has had to rely on the report of waste discharge process. California State Water Resources Control Board/RWQCB Stormwater Management Permitting While federal CWA National Pollutant Discharge Elimination System (NPDES) regulations allow two permitting options for construction-related stormwater discharges (individual permits and General Permits), the State Water Board has elected to adopt only one Statewide Construction General Permit at this time that will apply to all stormwater discharges associated with construction activity, except from those on Tribal Lands in the Lake Tahoe Hydrologic Unit, and those performed by the California Department of Transportation (Caltrans). The Construction General Permit requires all dischargers where construction activity disturbs greater than 1 acre of land or those sites less than 1 acre that are part of a common plan of development or sale that disturbs more than one acre of land surface to: 1. Develop and implement a Storm Water Pollution Prevention Plan (SWPPP) which specifies Best Management Practices (BMPs) that will prevent all construction pollutants from contacting stormwater with the intent of keeping all products of erosion from moving off-site into receiving waters. 2. Eliminate or reduce non-stormwater discharges to storm sewer systems and other waters of the nation. Achieve quantitatively-defined (i.e., numeric) pollutant-specific discharge standards, and conduct much more rigorous monitoring based on the project’s projected risk level. 3. Perform inspections of all BMPs. California Native Plant Protection Act State listing of plant species began in 1977 with the passage of the NPPA, which directed the CDFW to carry out the Legislature’s intent to “preserve, protect, and enhance endangered plants in this State.” The NPPA gave the CDFW the power to designate native plants as endangered or rare and to require permits for collecting, transporting, or selling such plants. CESA expanded on the original NPPA and enhanced legal protection for plants. CESA established categories for threatened and endangered species and grandfathered all rare animals—but not rare plants—into the act as Contra Costa County–Oak Road Townhouse Condominiums Project Biological Resources Draft EIR 3.3-14 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx threatened species. Thus, the State of California employs three listing categories for plants: rare, threatened, and endangered. The CNPS maintains a rank of plant species native to California that has low population numbers, limited distribution, or are otherwise threatened with extinction. This information is published in the Inventory of Rare and Endangered Vascular Plants of California. Potential impacts to populations of CNPS ranked plants receive consideration under CEQA review. The following identifies the definitions of the CNPS ranks: • Rank 1A: Plants presumed Extinct in California • Rank 1B: Plants Rare, Threatened, or Endangered in California and elsewhere • Rank 2A: Plants presumed extirpated in California but common elsewhere • Rank 2B: Plants rare, threatened, or endangered in California but more common elsewhere • Rank 3: Plants about which we need more information—A Review List • Rank 4: Plants of limited distribution—A Watch List All plants appearing on CNPS Rank 1 or 2 are considered to meet the CEQA Guidelines Section 15380 criteria. While only some of the plants ranked 3 and 4 meet the definitions of threatened or endangered species, potential impacts to these species or their habitats should be analyzed during the preparation of environmental documents relating to CEQA, as they may meet the definition of Rare or Endangered under CEQA Guidelines Section 15380 criteria. Local Habitat Conservation Plan The proposed project does not lie within the boundaries of any adopted Habitat Conservation Plan (HCP), Natural Community Conservation Plan (NCCP), or other approved local, regional, or State HCP. Contra Costa County General Plan The purpose of the Contra Costa County General Plan (General Plan) is to express the broad goals and policies, and specific implementation measures, which will guide decisions on future growth, development, and the conservation of resources through the year 2020. The following are the applicable General Plan goals and policies most pertinent to the proposed project with regard to protection and preservation of the natural resources in the area. Goal 8-A To preserve and protect the ecological resources of the County. Goal 8-B To conserve the natural resources of the County through control of the direction, extent and timing of urban growth. Goal 8-D To protect ecologically significant lands, wetlands, plant, and wildlife habitats. Goal 8-E To protect rare, threatened and endangered species of fish, wildlife, and plants, significant plant communities, and other resources which stand out as unique because of their scarcity, scientific value, aesthetic quality or cultural significance. Attempt to achieve a significant net increase in wetland values and functions within the County over the life of the General Plan.

Approach to Analysis Impacts on biological resources were evaluated based on the likelihood that special-status species, sensitive habitats, wildlife corridors, and protected trees are present on the project site, and the likely effects of project construction or operation on these resources. For the purposes of this Draft Environmental Impact Report (EIR), the word “substantial” as used in the significance thresholds above is defined by the following three principal components: • Magnitude and duration of the impact (e.g., substantial/not substantial), • Uniqueness of the affected resource (rarity), and • Susceptibility of the affected resource to disturbance. In this Biological Resources Analysis, the project site is defined as all areas directly affected by proposed project development. Specific Thresholds of Significance For purposes of this analysis, the following thresholds are used to evaluate the significance of biological resources impacts resulting from implementation of the proposed project. • Result in direct take or habitat removal or alteration for candidate, sensitive, or special-status species • Remove vegetation or damage water quality related to riparian habitat or other sensitive natural community • Remove, fill, or damage a federally protected wetland Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Biological Resources FirstCarbon Solutions 3.3-19 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx • Interrupt fish movement in an aquatic channel or impede terrestrial movement via a land corridor • Remove, damage, or replace trees designated by the Contra Costa County Tree Ordinance • Conflict with the provisions of an applicable habitat conservation plan Impact Evaluation Special-status Species Impact BIO-1: The proposed project could have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service. Construction Special-status Plant Species A plant species’ potential to occur on the project site was based on the presence of suitable habitats, soil types, and occurrences recorded by the CNPS and CNDDB within a 5-mile radius of the project site and a site survey conducted by Live Oak and FCS. A total of 20 special-status plant species were evaluated for their potential for occur within the project site (Appendix C; Table 1). Based on the absence of suitable habitat due to past development of the site all 20 special-status plant species have no potential to occur on-site. Suitable habitat requirements for special-status plant species include chaparral, riparian, alkaline or serpentine soils, these features are absent from the project site. Therefore, no special-status plant species have the potential to occur within the project site and no special-status plant species would be impacted by project construction. Special-status Wildlife Species A total of 28 special-status wildlife species were evaluated for their potential for occur within the project site (Appendix C; Table 2). Suitable habitat requirements for 23 special-status wildlife species include permanent or temporary aquatic features, dry open grassland with burrows, or chaparral and scrub, these features are absent from the project site. The remaining five special-status wildlife species (pallid bat, Townsend’s big-eared bat, big free-tailed bat, hoary bat, and white-tailed kite) as well as other birds protected under the MBTA and Fish and Game Code have potential to occur on the project site and, thus, have the potential to be impacted by project construction. Potential impacts to the five aforementioned special-status wildlife species and migratory birds are discussed below. Roosting Bats (pallid bat, Townsend’s big-eared bat, big free-tailed bat, and hoary bat) Vacant buildings and trees located throughout the project site may provide suitable roosting habitat for bats. Section 2000 and 4150 of the California Fish and Wildlife Code states that it unlawful to take or possess a number of species, including bats, without a license or permit as required by Section 3007. Potential direct and indirect impacts could occur to roosting bats during project construction due to removal of potential roosting habitat, these impacts would be considered significant under CEQA. These activities could potentially subject bats to risk of death or injury, and they are likely to avoid using the area until such construction activities have dissipated or ceased. Relocation, in turn, Contra Costa County–Oak Road Townhouse Condominiums Project Biological Resources Draft EIR 3.3-20 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx could cause hunger or stress among individual bats by displacing them into adjacent territories belonging to other individuals. Implementation of Mitigation Measure (MM) BIO-1a, which requires the project applicant to conduct a pre-construction survey and to implement further avoidance and minimization measures (if bats are present), would reduce potential impacts to roosting bats to a less than significant level under CEQA. Migratory and Nesting Birds The trees present throughout the project site could provide suitable habitat for a variety of species of nesting birds. Construction activities that occur during the avian nesting season (generally February 1 to August 31) could disturb nesting sites for bird species including special-status species such as the white-tailed kite as well as birds protected under the MBTA and the California Fish and Game Code. The removal of trees during the nesting season could result in direct harm to nesting birds, while noise, light, and other man-made disturbances may cause nesting birds to prematurely abandon their nests. Implementation of MM BIO-1b, which requires the project applicant to conduct a pre-construction survey and to implement further avoidance and minimization measures (if necessary), would reduce potential impacts to nesting birds to a less than significant level under CEQA. Operation An impact to the special-status wildlife species outlined above would be considered significant if operation of the proposed project resulted in a substantial, adverse change in ambient noise. The project site is generally surrounded by residential and commercial developments and is situated in an urban landscape with high amounts of traffic from local business operations, which create a baseline of ambient noise. The proposed project would increase traffic on local roadways and would introduce stationary noise sources through the operation of new a residential facility; however, noise emitted from the operation of the project would be within established standards and would not result in a significant increase in the ambient environment. Therefore, project implementation would not constitute a significant impact to wildlife species from operational noise including traffic noise. As such, all operational impacts would be considered less than significant. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures MM BIO-1a Roosting Bats 1. A qualified wildlife Biologist shall conduct surveys for special-status bats during the appropriate time of day to maximize detectability to determine whether bat species are roosting near the work area no more than 5 days prior to beginning ground disturbance and/or construction. Survey methodology may include visual surveys of bats (e.g., observation of bats during foraging period), inspection for Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Biological Resources FirstCarbon Solutions 3.3-21 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx suitable habitat, bat sign (e.g., guano), or use of ultrasonic detectors (Anabat, etc.). 2. Visual surveys will include trees within 100 feet of project construction activities. Prior to building demolition, the applicants for development on any project parcel shall ensure that a qualified Biologist (i.e., one familiar with the identification of bats and signs of bats) survey buildings proposed for demolition for the presence of roosting bats or evidence of bats. If no roosting bats or evidence of bats are found in the structure, demolition may proceed. If the Biologist determines bats are present, the Biologist shall exclude the bats from suitable spaces by installing one-way exclusion devices. After the bats vacate the space, the Biologist shall close off the space to prevent recolonization. Building demolition shall only commence after the Biologist verifies seven to 10 days later that the exclusion methods have successfully prevented bats from returning. To avoid impacts on non-volant (i.e., nonflying) bats, the Biologist shall only conduct bat exclusion and eviction from September 1 through March 31. Exclusion efforts shall be restricted during periods of sensitive activity. MM BIO-1b Migratory and Nesting Birds 1. If the project requires vegetation to be removed during the nesting season (February 1–August 31), pre-construction surveys shall be conducted 5 days prior to vegetation removal to determine whether or not active nests are present. 2. If an active nest is located during pre-construction surveys, a qualified Biologist shall determine an appropriately-sized avoidance buffer based on the species and anticipated disturbance level. Based on input from the Biologist, the project applicant will delineate the avoidance buffer using Environmentally Sensitive Area fencing, pin flags, and or yellow caution tape. The buffer zone will be maintained around the active nest site(s) until the young have fledged and are foraging independently. No construction activities shall be allowed within the avoidance buffer(s). 3. The qualified Biologist shall periodically monitor the active nest during construction activities to prevent any potential impacts that may result from the construction of the proposed project, until the young have fledged. Level of Significance After Mitigation Less than significant impact. Sensitive Natural Communities or Riparian Habitat Impact BIO-2: The proposed project would not have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service. Contra Costa County–Oak Road Townhouse Condominiums Project Biological Resources Draft EIR 3.3-22 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx Construction and Operation As noted in Section 3.3.3, the project site contains 75 trees, nine of which are valley oaks. The project site is developed and is almost entirely covered with impervious surfaces due to existing development to the extent that no natural habitat remains present on-site. The trees that are present are located in pockets surrounded by hardscaped areas. Historical aerial photographs indicate that most of the oak trees on-site appear to be ornamental plantings; thus, they are not part of a natural community (e.g., naturally occurring oak savanna or oak woodland).25 The project site does not contain riparian habitat or other sensitive natural communities identified in local or regional plans, policies, and regulations or by the CDFW or USFWS. Therefore, the project would not directly or indirectly adversely impact any riparian habitat or sensitive natural community, and there would be no impacts from project construction or operation. Level of Significance No impact. Wetlands and Jurisdictional Features Impact BIO-3: The proposed project would not have a substantial adverse effect on State or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means. Construction and Operation The project site is developed and does not contain jurisdictional drainages, wetlands, hydrophytic vegetation or soils. On-site stormwater runoff sheet flows across the project site and is captured by drainage inlets connected by municipal underground storm drain pipes that discharge into existing storm drainage infrastructure. As such, the proposed project would not directly or indirectly remove, fill or hydrologically interrupt State or federally protected wetlands. No impacts would result from project construction or operation. Level of Significance No impact. Fish and Wildlife Movement Corridors Impact BIO-4: The proposed project would not interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of wildlife nursery sites. Construction and Operation The proposed project would not interfere with the movement of migratory fish, migratory wildlife corridors, or the use of wildlife nursery sites. The project site is in a built out urban area and does not contain any habitat features such as riparian corridors or waterways that could function as wildlife corridors. Moreover, there are multiple barriers to wildlife migration including I-680 and 25 Google Earth Pro, 1937. 37° 55' 27.33"N, 122° 03' 31.52"W, Eye alt 3,281 ft. Accessed June 7, 2021.

As such, the impact on migratory fish and wildlife would be less than significant. Level of Significance Less than significant impact. Local Policies or Ordinances Impact BIO-5: The proposed project could conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance. Construction The Ordinance Code Chapter 816-6 lists the protected trees, permit requirements, and the applications process for tree removal. A significant impact would result if construction or operation of the project would conflict with these policies and provisions. The Tree Report provides an inventory and preliminary evaluation of all trees over 6 inches in diameter within the project site. Trees that were surveyed were numbered, tagged, identified, measured, and evaluated. According to the Tree Report, a total of 74 trees would be removed as part of project implementation, one tree would be relocated, and six off-site trees would be preserved. Of the trees proposed for removal, 73 trees are considered protected due to their size, the remaining eight trees do not qualify as protected based on the Tree Protection and Preservation Ordinance. If not properly protected, the trees proposed for preservation could also be subject to injury or inadequate maintenance during construction, which represents a potentially significant impact. The response of individual trees would depend on the amount of excavation and grading, the care with which demolition is undertaken, and the construction methods. As the construction of the proposed project requires the removal of trees subject to the Contra Costa County Tree Protection and Preservation Ordinance, the applicant would be required to prepare and implement a tree replacement plan. In addition, remaining trees that are proposed for preservation on the project site would be preserved through the implementation of the tree preservations guidelines identified and outlined in the Tree Report and in the Contra Costa County Tree Protection and Preservation Ordinance. As a part of approval for development, the applicant would be required to comply with the County’s tree ordinance, including tree removal permits and protection of preserved trees. Implementation of MM BIO-5a, which requires the project applicant to implement a tree replacement plan, and MM BIO-5 b requiring the project applicant to implement tree preservation guidelines during construction, impacts related to consistency with local policies or ordinances that protect biological resources would be less than significant. Operation Impacts related to the consistency of the project with local biological resources policies and ordinances are limited to construction impacts. Because the project applicant would be required to monitor, protect, and maintain preserved trees, no operational impacts would occur.

Mitigation Measures MM BIO-5a Prepare and Implement a Tree Replacement Plan A Tree Replacement Plan shall be submitted and approved by Department of Conservation and Development, Community Development Division (CDD) prior to the removal of trees, prior to issuance of a demolition or grading permit, whichever occurs first. The Tree Replacement Plan shall designate the approximate location, number, and sizes of trees to be planted. Trees shall be planted prior to requesting a final inspection of the building permit. MM BIO-5b Implement Tree Preservation Guidelines During Construction Tree protection guidelines shall be implemented during construction throughout the clearing, grading, and construction phases as outlined on pages 12 and 13 in the arborist report prepared by HortScience dated January 4, 2021. Level of Significance After Mitigation Less than significant impact. Local, Regional, or State Habitat Conservation Plan Impact BIO-6: The proposed project would not conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State habitat conservation plan. Construction and Operation The project site does not fall within the coverage area of an HCP or NCCP. The project site is roughly 5 miles west of the East Contra Costa County HCP area, the nearest habitat conservation plan area. Therefore, there would be no construction or operational impacts related to consistency with a conservation plan. Level of Significance No impact. 3.3.5 - Cumulative Impacts Special-status Species The geographical scope of the cumulative Biological Resources Analysis is the boundaries of the County. This section focuses on the areas of the County, including the City of Pleasant Hill and the City of Walnut Creek, near where the project site is located. Development listed in Table 3-1 (Refer to Chapter 3.0, Environmental Impact Analysis) consists predominantly of residential and commercial development. The majority of this area is highly developed and contains a mix of residential, commercial, and industrial buildings. There are several waterways in within the boundaries of the Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Biological Resources FirstCarbon Solutions 3.3-25 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx County, such as such as the Contra Costa Canal and the Walnut Creek waterway. The majority of projects are occurring in close vicinity of the project site and, subsequently, occurring in previously developed or highly disturbed areas. The developed urban characteristics of the previously mentioned areas will preclude the presence of many special-status species. However, the varying degree of trees present in and around the urban areas may provide suitable nesting habitat for birds protected by the MBTA. Standard pre-construction surveys and, if necessary, avoidance procedures would be required for cumulative projects with the potential to impact nesting birds and protected bat species. While there are a limited number of isolated pockets of natural habitat that can support special-status wildlife and plant species, the built-up nature of the previously listed areas precludes the possible cumulative impacts to biological resources related to special-status wildlife and plant species. Sensitive Natural Communities or Riparian Habitat Within the County, the City of Pleasant Hill, and the City of Walnut Creek, there are several small waterbodies, including the Walnut Creek waterway, Grayson Creek, and associated riparian habitats. These areas are considered sensitive natural communities. The majority of current developments are designed to address future growth problems, prevent urban sprawl, and minimize developmental impacts to sensitive natural communities. This is accomplished by designing projects to occur in previously developed or highly disturbed areas that the characteristics of lack sensitive natural communities or riparian habitat. As such, the project, in conjunction with other cumulative projects, would result in a less than significant cumulative impact related to sensitive natural communities and associated riparian habitat. Waters of the United States and Waters of the State The County, the City of Pleasant Hill, and the City of Walnut Creek contain several areas that would be considered jurisdictional features. As such, current projects are occurring in a highly developed and disturbed area with low potential for jurisdictional features to be impacted by project development. If any issues were to arise due to current development, the applicant would be required to obtain appropriate permits from the USACE, RWQCB, and CDFW, compensate for loss of waters of the United States/State through re-creation or payment of mitigation credits, and re- creation of lost habitat. Due to the limited scope of current projects, which are occurring in highly developed and disturbed areas, it is expected there will be a less than significant cumulative impact related to waters of the United States/State. Local Policies or Ordinances The project would remove approximately 74 of 75 on-site trees (73 code-protected trees and approximately one not code-protected tree). Other projects listed in Table 3-1 may require the removal or encroachment on certain protected trees as listed by the County’s Ordinance Code, the Walnut Creek Municipal Code, or the Pleasant Hill Municipal Code. As previously mentioned, many of the current development projects are occurring in previously developed or disturbed areas. As such, a limited number of trees within the geographical scope are likely to occur. Current project developments may require an Arborist report to determine the identity of trees planned for removal or encroachment. Therefore, the project, in conjunction with other future development projects, Contra Costa County–Oak Road Townhouse Condominiums Project Biological Resources Draft EIR 3.3-26 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-03 Biological Resources.docx would be required to adhere to applicable tree ordinances and regulations set by the County and the City of Walnut Creek and City of Pleasant Hill resulting in a less than significant cumulative impact to biological resources related to local policies and ordinances. Fish and Wildlife Movement Corridors The main wildlife corridor in the vicinity of the project site is the Walnut Creek waterway, which generally borders the I-680 corridor, stretching from northern San Ramon to Suisun Bay. There are several small water channels and tributaries that are located within the geographical scope of this project. The project site is located to the west of the waterway and due to the size and location of the proposed project it will not result in any potential impacts to wildlife corridors. Any current development that occurs within the geographic scope of the County, the City of Walnut Creek and the City of Pleasant Hill will have to take into account the potential impact to these corridors. The areas surrounding the potential corridors within the previously mentioned geographical scope are highly developed, further impeding the movement of species out from these areas. As such, there will be a less then significant cumulative impact to biological resources related to movement corridors for fish and wildlife. Habitat and Natural Community Conservation Plan Consistency The project site is not located within the East Contra Costa County HCP. The HCP provides for comprehensive species, wetlands, and ecosystem conservation, and contributes to the recovery of endangered species in Eastern Contra Costa County. Any current project sites within the boundaries of the HCP will have to adhere by the additional regulations and guidelines set forth. This may include additional surveys for listed species, developments fees, and various other directives. As such, there will be a less then significant cumulative impact to biological resources relating to developments occurring in Habitat Community Conservation Plans. Level of Cumulative Significance Less than significant impact. 26480017 • 06/2021 | 3.3-1_CNDDB.mxd CONTRA COSTA COUNTYOAK ROAD TOWNHOUSE CONDOMINIUMSENVIRONMENTAL IMPACT REPORT Exhibit 3.3-1CNDDB Special-StatusSpecies Occurrences (5-mile radius) Source: Bing Street Imagery.

Recommendations provided in these reports to address potential impacts on cultural resources during ground-disturbing activities are incorporated into this section where appropriate. The following comments related to Cultural and Tribal Cultural Resources (TCRs) were received in response to the NOP: • Recommendation to consult with California Native American Tribes that are traditionally and culturally affiliated with the geographic area of the proposed project. • Notification and explanation of requirements under Assembly Bill (AB) 52 and Senate Bill (SB) 18. 3.4.2 - Environmental Setting Overview The term “cultural resources” encompasses historic, archaeological, tribal cultural resources, and burial sites. Below is a brief summary of each component: • Historic Resources: Historic resources are associated with the recent past. In California, historic resources are typically associated with the Spanish, Mexican, and American periods in the State’s history and are generally less than 200 years old. Historic resources often take the form of buildings, structures, and other elements of the built environment. • Archaeological Resources: Archaeology is the study of artifacts and material culture with the aim of understanding human activities and cultures in the past. Archaeological resources may be associated with prehistoric indigenous cultures as well as historic periods. • Tribal Cultural Resources: TCRs include sites, features, places, or objects that are of cultural value to one or more California Native American Tribes. • Burial Sites, Cemeteries, and Native American Burial Sites: Burial sites and cemeteries are formal or informal locations where human remains have been interred and that are of cultural value to one or more California Native American Tribes. Cultural Setting Following is a brief overview of the prehistory, ethnography, and historic background, providing a context in which to understand the background and relevance of sites found in the vicinity of the Contra Costa County–Oak Road Townhouse Condominiums Project Cultural Resources and Tribal Cultural Resources Draft EIR 3.4-2 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\EIR\3 - Draft EIR\26480017 Sec03-04 Cultural-Tribal Cultural Resources.docx project site. This section is not intended to be a comprehensive review of the current resources available; rather, it serves as a general overview. Further details can be found in ethnographic studies, mission records, and major published sources.1,2,3,4,5,6,7 Prehistoric and Ethnographic Background In general, archaeological research in the greater San Francisco Bay Area has focused on coastal areas, where large shellmounds were relatively easily identified on the landscape. This research and its chronological framework, however, is relevant to and has a bearing on our understanding of prehistory in areas adjacent to the San Francisco Bay Area, including modern Contra Costa County. The San Francisco Bay Area supported a dense population of hunter-gatherers over thousands of years, leaving a rich and varied archaeological record. The Bay Area was a place of incredible language diversity, with seven languages spoken at the time of Spanish settlement in 1776. The diverse ecosystem of the Bay and surrounding lands supported an average of three to five persons per square mile, but reached 11 persons per square mile in the North Bay. At the time of Spanish contact, the people of the Bay Area were organized into local tribelets that defended fixed territories under independent leaders. Typically, individual Bay Area tribelets included 200 to 400 people distributed among three to five semi-permanent villages, within territories measuring approximately 10 to 12 miles in diameter.8 Native American occupation and use of the greater Bay Area, including the regions comprising modern Richmond, extends over 5,000 to 7,000 years and may be longer. Early archaeological investigations in Central California were conducted at sites located in the Sacramento-San Joaquin Delta region. The first published account documents investigations in the Lodi and Stockton area.9 The initial archaeological reports typically contained descriptive narratives, with more systematic approaches sponsored by Sacramento Junior College in the 1930s. At the same time, University of California at Berkeley excavated several sites in the lower Sacramento Valley and Delta region, which resulted in recognizing archaeological site patterns based on variations of inter-site assemblages. Research during the 1930s identified temporal periods in Central California prehistory and provided an initial chronological sequence.10,11 In 1939, Lillard noted that each cultural period led directly to the next and that influences spread from the Delta region to other regions in Central California.12 In 1 Kroeber, A.L. 1925.

This system proposed a uniform, linear sequence of cultural succession.13 The CCTS was challenged by Gerow, whose work looked at radiocarbon dating to show that Early and Middle Horizon sites were not subsequent developments but, at least partially, contemporaneous.14,15,16 To address some of the flaws in the CCTS, Fredrickson introduced a revision that incorporated a system of spatial and cultural integrative units.17 Fredrickson separated cultural, temporal, and spatial units from each other and assigned them to six chronological periods: Paleo-Indian (12,000 to 8000 Before Present [BP]); Lower, Middle and Upper Archaic (8000 BP to 1500 BP), and Emergent (Upper and Lower, 1500 BP to historic period). The suggested temporal ranges are similar to earlier horizons, which are broad cultural units that can be arranged in a temporal sequence.18 In addition, Fredrickson defined several patterns—a general way of life shared within a specific geographical region. These patterns include: • Windmiller Pattern or Early Horizon (5000 to 3000 BP) • Berkeley Pattern or Middle Horizon (3000 to 1500 BP) • Augustine Pattern or Late Horizon (1500 BP to historic period) Brief descriptions of these temporal ranges and their unique characteristics follow. Windmiller Pattern or Early Horizon (5000 to 3000 BP) Characterized by the Windmiller Pattern, the Early Horizon was centered in the Cosumnes district of the Delta and emphasized hunting rather than gathering, as evidenced by the abundance of projectile points in relation to plant processing tools. Additionally, atlatl, dart, and spear technologies typically included stemmed projectile points of slate and chert but minimal obsidian. The large variety of projectile point types and faunal remains suggests exploitation of numerous types of terrestrial and aquatic species.19,20 Burials occurred in cemeteries and intra-village graves. These burials typically were ventrally extended, although some dorsal extensions are known with a westerly orientation and a high number of grave goods. Trade networks focused on acquisition of ornamental and ceremonial objects in finished form rather than on raw material. The presence of artifacts made of exotic materials such as quartz, obsidian, and shell indicate an extensive trade network that may represent the arrival of Utian populations into Central California. Also indicative of this period are rectangular Haliotis and Olivella shell beads, and charmstones that usually were perforated. 13 Beardsley, R.K. 1948. “Cultural Sequences in Central California Archaeology.” American Antiquity 14:1-28. 14 Gerow, B.A. 1954.

This period exhibited a strong milling technology represented by minimally shaped cobble mortars and pestles, although metates and manos were still used. Dart and atlatl technologies during this period were characterized by non-stemmed projectile points made primarily of obsidian. Fredrickson suggests that the Berkeley Pattern marked the eastward expansion of Miwok groups from the San Francisco Bay Area.21 Compared with the Early Horizon, there is a higher proportion of grinding implements at this time, implying an emphasis on plant resources rather than on hunting. Typical burials occurred within the village with flexed positions, variable cardinal orientation, and some cremations. As noted by Lillard, the practice of spreading ground ochre over the burial was common at this time.22 Grave goods during this period are generally sparse and typically include only utilitarian items and a few ornamental objects. However, objects such as charmstones, quartz crystals, and bone whistles occasionally were present, which suggest the religious or ceremonial significance of the individual.23 During this period, larger populations are suggested by the number and depth of sites compared with the Windmiller Pattern. According to Fredrickson, the Berkeley Pattern reflects gradual expansion or assimilation of different populations rather than sudden population replacement and a gradual shift in economic emphasis.24 Augustine Pattern or Late Horizon (1500 BP to Historic Period) The Late Horizon is characterized by the Augustine Pattern, which represents a shift in the general subsistence pattern. Changes include the introduction of bow and arrow technology; and most importantly, acorns became the predominant food resource. Trade systems expanded to include raw resources as well as finished products. There are more baked clay artifacts and extensive use of Haliotis ornaments of many elaborate shapes and forms. Burial patterns retained the use of flexed burials with variable orientation, but there was a reduction in the use of ochre and widespread evidence of cremation.25 Judging from the number and types of grave goods associated with the two types of burials, cremation seems to have been reserved for individuals of higher status, whereas other individuals were buried in flexed positions. Research indicates that Augustine Pattern represents expansion of the Wintuan population from the north, which resulted in combining new traits with those established during the Berkeley Pattern.26 Central California research has expanded from an emphasis on defining chronological and cultural units to a more comprehensive look at settlement and subsistence systems. This shift is illustrated by the early use of burials to identify mortuary assemblages and more recent research using 21 Fredrickson, D.A. 1973. Early Cultures of the North Coast Ranges, California.

The Ohlone (Costanoan) The San Francisco Bay Area consisted of several independent tribal territories during the prehistoric and early historic periods. Native Peoples largely spoke dialects of five distinct languages: Costanoan (Ohlone), Bay Miwok, Plains Miwok, Patwin, and Wappo. Various tribelets that were part of the Ohlone tribe of California Native Americans occupied the project vicinity at the time of European contact.28 The Ohlone group designates a language family consisting of eight branches of the Ohlone language that are considered too distinct to be dialects, wherein each is related to its geographically adjacent neighbors. These groups lived in approximately 50 separate and politically autonomous tribelet areas, each with one or more permanent villages, between the North San Francisco Bay and the lower Salinas River.29 The tribal group that most likely occupied the project area was of the Karkin ethnic group, whose territory extended over the Carquinez Strait region in the northeast portion of the San Francisco Bay estuary. Linguist-missionary Felipe Arroyo de la Cuesta documented that they spoke the Karkin language at Mission Dolores in 1821. His records show that the Karkin language was a distinct branch of Ohlone, strikingly different from the neighboring Chochenyo Ohlone language or other Ohlone languages spoken farther south. The various Ohlone tribes subsisted as hunter-gatherers and relied on local terrestrial and marine flora and fauna for subsistence.30 The predominant plant food source was the acorn, but they also exploited a wide range of other plants, including various seeds, buckeye, berries, and roots. Protein sources included grizzly bear, elk, sea lions, antelope, and black-tailed deer as well as smaller mammals such as raccoon, brush rabbit, ground squirrels, and wood rats. Waterfowl, including Canadian geese, mallards, green-winged teal, and American widgeon, were captured in nets using decoys to attract them. Fish also played an important role in the Ohlone diet and included steelhead, salmon, and sturgeon.31 Like other Native Californians, the Ohlone managed their environment to improve it for their use. For example, the Ohlone burned grass and brush lands annually in order to improve productivity of forage habitat for deer and rabbits, and to enhance safety by keeping the land open with clear sight lines to better spot predators or neighbors. The Ohlone were politically organized into autonomous tribelets that had distinct cultural territories. Individual tribelets contained one or more villages with a number of seasonal camps for resource procurement within the tribelet territory. The tribelet chief could be either male or female, and the 27 Dickel, D.N., P. D. Schulz, and H.M. McHenry. 1984. Central California: Prehistoric Subsistence Changes and Health.

The tribelet chief and council were essentially advisers to the community and were responsible for feeding visitors, directing hunting and fishing expeditions, ceremonial activities, and warfare on neighboring tribelets. Regional Historic Background Spanish Period (1769-1821) According to Hart, Spanish colonial policy from 1769-1821 was directed at the founding of presidios, missions, and secular towns, with the land held by the Crown. The depletion of the coastal populations resulted in Spanish missionaries shifting to conversion of the interior peoples. Spanish mission records indicate that by 1800, Ohlone speaking peoples, and other villages were being taken to Mission Dolores, and that Mission Sonoma, built in 1823, was baptizing tribal members until secularization of the missions in 1833. Their traditional lifeways apparently disappeared by 1810 due to disruption by Euro American diseases, a declining birth rate, and the impact of the mission system . After secularization of the missions between 1834 and 1836, some Native Americans returned to traditional religious and subsistence practices while others labored on Mexican ranchos. Thus, multi-ethnic Indian communities grew up in and around the area and provided informant testimony to ethnologists from 1878 to 1933.32 Mexican Period (1821-1848) The Mexican Period, 1821 to 1848, was marked by secularization and division of mission lands among the Californios as land grants, termed ranchos. During this period, Mariano G. Vallejo assumed authority of Sonoma Mission and established a rapport with the Native Americans who were living there. In particular, Vallejo worked closely with Chief Solano, a Patwin who served as Vallejo’s spokesperson when problems with Native American tribes arose. The large rancho lands often were worked by Native Americans who were used as forced labor. Shoup and Milliken state that mission secularization removed the social protection and support on which Native Americans had come to rely. It exposed them to further exploitation by outside interests, often forcing them into a marginal existence as laborers for large ranchos.33 Following mission secularization, the Mexican population grew as the Native American population continued to decline. Euro American settlers began to arrive in California during this period and often married into Mexican families, becoming Mexican citizens, which made them eligible to receive land grants. In 1846, on the eve of the U.S.-Mexican War (1846 to 1848), the estimated population of California was 8,000 non-natives and 10,000 Native Americans. However, these estimates have been debated. Cook suggests the Native American population was 100,000 in 1850; the U.S. Census of 1880 reports the Native American population as 20,385.34 Gold Rush and American Expansion Period (1848-1864) In 1848, James W. Marshall discovered gold at Coloma in modern-day El Dorado County, which started the Gold Rush into the region that forever altered the course of California’s history. The arrival of thousands of gold seekers in the territory contributed to the exploration and settlement of 32 Hart, James D. 1987. A Companion to California. 33 Shoup, Laurence H., and Randall T.

By late 1848, approximately four out of five men in California were gold miners. The Gold Rush originated along the reaches of the American River and other tributaries to the Sacramento River, and Hangtown, present-day Placerville, became the closest town offering mining supplies and other necessities for the miners in El Dorado County. Gold subsequently was found in the tributaries to the San Joaquin River, which flowed north to join the Sacramento River in the great Delta east of San Francisco Bay.35 By 1864, California’s Gold Rush had essentially ended. The rich surface and river placers were largely exhausted and the miners either returned to their homelands or stayed to start new lives in California. After the Gold Rush, people in towns such as Jackson, Placerville, and Sonora turned to other means of commerce, such as ranching, agriculture, and timber production. With the decline of gold mining, agriculture and ranching came to the forefront in the State’s economy. California’s natural resources and moderate climate proved well suited for cultivation of a variety of fruits, nuts, vegetables, and grains.36 History of Contra Costa The east side of San Francisco Bay, directly across from the City of San Francisco, became known as the “opposite coast” (or contra costa) by the Spanish. The County was formed in December of 1849 and is one of the original 27 California counties, with the County seat at Martinez.37 Contra Costa County, like much of California, was seen as a land of economic opportunity, not just for its mining resources but also for its productive land where farmers could cultivate a variety of crops. Agriculture became important in the California economy in the late 1850s, and through to the 1860s, homesteading became a means by which people could own and operate a family farm. The decidedly agricultural focus also underpins the historical significance of the Spanish colonial and Mexican era of land grants. As early as 1882, special interests advertised the County’s virtues as a place to cultivate. Early settlers began to speak of beneficial soils that support a range of crops— pears, prunes, peaches, almonds, walnuts and grapes flourished—with seasonal rainfall, and favorable climates. In addition, the County is strategically located at crossing of trade routes with a waterfront location and relative closeness to the San Francisco metropolis. Large-scale commercial operations began to capitalize on mechanical innovations just as irrigation developed in the early 1880s. Consequently, competing economic interests caused land prices to increase and make family farming a less profitable enterprise. Throughout the 1960s and 1970s, large companies followed their employees to suburban areas east of San Francisco. The establishment of large population centers fostered the development of equally large shopping centers. To meet demand on infrastructure, the State modernized highways and roadways, and established the Bay Area Rapid Transit (BART). 35 Robinson, W.W. 1948.

The records search included a review of confidential and non-confidential files, including maps and site records. The California Office of Historic Preservation (OHP) Built Environment Resources Directory (BERD), National Register of Historic Places (NRHP), California Register of Historical Resources (CRHR), California Historic Landmarks List (CHL), California Points of Historical Interest (CPHI), Archaeological Determinations of Eligibility, and California Inventory of Historic Resources were also reviewed. The NWIC records search results indicate that 13 cultural resources have been mapped within a 0.5- mile radius of the project site (Table 3.4-1). Of these, one is a prehistoric archaeological site and 12 are built environment resources. The prehistoric archaeological site is recorded as being within the search radius. Of the 12 built environment resources, 11 are historic-era buildings (single-family residences) and one is a historic-era structure (Contra Costa Canal). None of the 13 resources are within or in close proximity to (within 50 feet of) the project site. A review of the BERD identified three unmapped built environment resources within a 0.5-mile radius project site that are not on file at the NWIC (2700 Oak Road, 2616 North Main Street, and 2678 North Main Street–see Table 3.4-1). One resource is a single-family residence (2700 Oak Road) located approximately 0.07 miles south-southeast of the project site. One resource is an industrial property (2616 North Main Street) located about 0.33 mile southwest of the project site. One resource does not have a description provided (2678 North Main Street) and is located about 0.25 miles south-southwest of the project site. All of these resources were determined ineligible for the NRHP through the Section 106 process and were not evaluated for the CRHR or for a local listing. None of these resources were in close proximity to the project site. A review of the NRHP, CRHR, CHL, CPHI, Archaeological Determinations of Eligibility, and California Inventory of Historic Resources did not identify any additional resources.

Native American Heritage Commission Record Search and Tribal Correspondence The NAHC maintains a confidential Sacred Lands File (SLF) which contains sites of traditional, cultural, or religious value to the Native American community. The NAHC was contacted on August 13, 2020, to request a search of the SLF. The NAHC responded to the request in a letter dated August 18, 2020, and indicated that the SLF results were negative. The NAHC also provided a list of eight Native American tribes to contact as these tribes may have knowledge of cultural resources in the project site. On May 11, 2021, ESA contacted the eight tribes recommended by the NAHC to obtain additional knowledge about potential resources on-site. On May 18, ESA spoke to a representative from Indian Canyon Mutsun Band of Costanoan, who requested that a Native American Monitor be on-site if any burials or Native American artifacts are encountered. On May 18, 2021, Wintun Rancheria responded to the tribal consultation letter stating they did not have concerns about the proposed project. NAHC and tribal correspondence can be found in Appendix D. Cultural Resources Pedestrian Survey A survey of the project site was conducted by ESA Cultural Resources Staff, Candace Ehringer, MA, RPA, on August 11, 2020. All areas with visible ground surface were surveyed in 5-meter transects. Ground visibility was less than 5 percent. Soil types observed consisted of dark gray silty loam. No archaeological resources were observed. On-site buildings were photographed. Appendix D provides photographs of the existing site conditions. The site is currently developed with buildings and structures related to the former Palmer School, which was established in 1939. A cursory review of historic aerials indicates that some existing buildings and structures were present as early as 1965, although the exact dates of construction are unknown. It is unclear if any existing buildings or structures were constructed earlier than the 1960s. The survey identified one potential historical resource within the project site – the Palmer School, which was established in 1939. A review of aerial photographs indicates that some existing on-site buildings and structures date to at least as early as 1965, indicting they are more than 55 years old. The age threshold for consideration for listing in the California Register is 50 years.

The purpose of the study was to identify and evaluate the historical significance of the former Palmer School located within the project site. ESA reviewed the report to understand the historical context of the project site and to assist in assessing if subsurface deposits related to the school’s use, if present, could be potentially significant. The history of the school was excerpted from the report and is provided in the Historic Setting section of the report. The report evaluated the campus under all four CRHR criteria. Under Criterion 1 (significant events), the report concluded that the Palmer School “was not found to have contributed in a significant way to the broad patterns of education in the local or regional history.” Under Criterion 2 (important persons), the report concluded that “research did not find the Palmer family to have played an important role in the nation or California’s history.” Under Criterion 3 (architecture, artistic value), the report concluded that “as a whole, the campus does not represent distinctive characteristics or methods of construction” and “the overall campus buildings do not possess high artistic values.” Under Criterion 4, the report concluded that “the common construction of the buildings does not have the potential to yield information important to the history of the State or nation.” Because the project site does not meet any of the four criteria, the property is not a potentially historic resource under the California Environmental Quality Act (CEQA). The study can be found in Appendix D. Summary of Existing Cultural Resources at the Project Site Historic Architectural Resources Based on the pedestrian survey and archival research, no known historic architectural resources are located within the project site boundaries. The survey identified the Palmer School as a potential historical resource within the project site, but further evaluation lead to the conclusion that the property is not eligible for the CRHR, and is therefore not a potentially historic resource under CEQA. The Palmer School was established in 1939. No previously recorded historical resources are present within or in close proximity to (within 50 feet of) the project site. Archaeological Resources No archaeological resources were identified within the project site as a result of the archival research or survey. As noted in Table 3.4-1, there is one site (CA-CCO-23) within a 0.5-mile radius of the project site within a similar context as the project site. However, this resource is not located within close proximity to the project site. The eligibility status of the prehistoric archaeological site is unknown. No known archaeological resources constraints exist within the project site. However, archaeological resources are often obscured from view and can be uncovered during construction activities. Given the occurrence of a nearby prehistoric archaeological site, it appears there is a potential for prehistoric resources to occur within the project site. Tribal Cultural Resources On May 18, 2021, ESA spoke to a representative from Indian Canyon Mutsun Band of Costanoan, who requested that a Native American Monitor be on-site if any burials or Native American artifacts Contra Costa County–Oak Road Townhouse Condominiums Project Cultural Resources and Tribal Cultural Resources Draft EIR 3.4-12 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\EIR\3 - Draft EIR\26480017 Sec03-04 Cultural-Tribal Cultural Resources.docx are encountered. While no TCRs have been recorded within the project site, it is possible they could be discovered during project construction. 3.4.3 - Regulatory Framework Federal National Historic Preservation Act The National Historic Preservation Act of 1966 (NHPA), as amended, established the NRHP, which contains an inventory of the nation’s significant prehistoric and historic properties. Under 36 Code of Federal Regulations 60, a property is recommended for possible inclusion on the NRHP if it is at least 50 years old, has integrity, and meets one of the following criteria: • It is associated with significant events in history, or broad patterns of events. • It is associated with significant people in the past. • It embodies the distinctive characteristics of an architectural type, period, or method of construction; or it is the work of a master or possesses high artistic value; or it represents a significant and distinguishable entity whose components may lack individual distinction. • It has yielded, or may yield, information important in history or prehistory. Certain types of properties are usually excluded from consideration for listing in the NRHP, but they can be considered if they meet special requirements in addition to meeting the criteria listed above. Such properties include religious sites, relocated properties, graves and cemeteries, reconstructed properties, commemorative properties, and properties that have achieved significance within the past 50 years. Archaeological Resources Protection Act The Archaeological Resources Protection Act (ARPA) amended the Antiquities Act of 1906 (16 United States Code [USC] §§ 431–433) and set a broad policy that archaeological resources are important to the nation and should be protected and required special permits before the excavation or removal of archaeological resources from public or Indian lands. The purpose of the ARPA was to secure, for the present and future benefit of the American people, the protection of archaeological resources and sites that are on public lands and Indian lands, and to foster increased cooperation and exchange of information between governmental authorities, the professional archaeological community, and private individuals having collections of archaeological resources and data that were obtained before October 31, 1979. American Indian Religious Freedom Act The American Indian Religious Freedom Act established federal policy to protect and preserve the inherent rights of freedom for Native groups to believe, express, and exercise their traditional religions. These rights include but are not limited to access to sites, use and possession of sacred objects, and freedom to worship through ceremonials and traditional rites.

It clarifies the ownership of human remains and sets forth a process for repatriation of human remains and associated funerary objects and sacred religious objects to the Native American groups claiming to be lineal descendants or culturally affiliated with the remains or objects. It requires any federally funded institution housing Native American Remains or artifacts to compile an inventory of all cultural items within the museum or with its agency and to provide a summary to any Native American tribe claiming affiliation. State CEQA Guidelines Section 15064.5(a)—CEQA Definition of Historical Resources CEQA Guidelines Section 15064.5(a), in Title 14 of the California Code of Regulations, defines a “historical resource” as: 1. A resource listed in, or determined to be eligible by the State Historical Resources Commission, for listing in the California Register of Historical Resources. 2. A resource included in a local register of historical resources, as defined in Section 5020.1(k) of the Public Resources Code or identified as significant in a historical resource survey meeting the requirements of Section 5024.1(g) of the Public Resources Code, shall be presumed to be historically or culturally significant. Public agencies must treat any such resource as significant unless the preponderance of evidence demonstrates that it is not historically or culturally significant. 3. Any object, building, structure, site, area, place, record, or manuscript which a lead agency determines to be historically significant or significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California may be considered to be a historical resource, provided the lead agency’s determination is supported by substantial evidence in light of the whole record. Generally, a resource shall be considered by the lead agency to be “historically significant” if the resource meets the criteria for listing on the California Register of Historical Resources. 4. The fact that a resource is not listed in, or determined to be eligible for listing in the California Register of Historical Resources, not included in a local register of historical resources (pursuant to Section 5020.1(k) of the Public Resources Code), or identified in a historical resources survey (meeting the criteria in Section 5024.1(g) of the Public Resources Code) does not preclude a lead agency from determining that the resource may be a historical resource as defined in Public Resources Code Sections 5020.1(j) or 5024.1. Therefore, under the CEQA Guidelines, even if a resource is not included on any local, State, or federal register, or identified in a qualifying historical resources survey, a lead agency may still determine that any resource is a historical resource for the purposes of CEQA if there is substantial evidence supporting such a determination. A lead agency must consider a resource to be historically significant if it finds that the resource meets the criteria for listing in the CRHR.

Cultural resources are recognized as nonrenewable resources and receive additional protection under the Public Resources Code and CEQA. CEQA Guidelines Section 15064.5(a)(3)—California Register of Historical Resources Criteria As defined by CEQA Guidelines, Section 15064.5(a)(3)(A-D), a resource shall be considered historically significant if the resource meets the criteria for listing on the CRHR. The CRHR and many local preservation ordinances have employed the criteria for eligibility to the NRHP as a model (see criteria described above under the description of the NHPA), since the NHPA provides the highest standard for evaluating the significance of historic resources. A resource that meets NRHP criteria is clearly significant. In addition, a resource that does not meet NRHP standards may still be considered historically significant at a local or State level. California Public Resources Code Section 5024.1—California Register of Historical Resources Section 5024.1 of the Public Resources Code states that the CRHR is a guide to be used by State and local agencies, private groups, and citizens to identify the State’s historical resources and to indicate what properties are to be protected from substantial adverse change. Administration of the CRHR is to be overseen by the NAHC. Section 5024.1 indicates that the register shall include historical resources determined by the NAHC, according to adopted procedures, to be significant and to meet the criteria in subdivision (c). CEQA Guidelines 15064.5(c)—Effects on Archaeological Resources CEQA Guidelines state that a resource need not be listed on any register to be found historically significant. CEQA Guidelines direct lead agencies to evaluate archaeological sites to determine whether they meet the criteria for listing in the CRHR. If an archaeological site is a historical resource, in that it is listed or eligible for listing in the CRHR, potential adverse impacts to it must be considered. If an archaeological site is considered not to be a historical resource but meets the definition of a “unique archaeological resource” as defined in Public Resources Code Section 21083.2, then it would be treated in accordance with the provisions of that section. CEQA Guidelines Section 15064.5(d)—Effects on Human Remains Native American human remains and associated burial items may be significant to descendant communities and/or may be scientifically important for their informational value. They may be significant to descendant communities for patrimonial, cultural, lineage, and religious reasons. Human remains may also be important to the scientific community, such as prehistorians, epidemiologists, and physical anthropologists. The specific stake of some descendant groups in ancestral burials is a matter of law for some groups, such as Native Americans (CEQA Guidelines § 15064.5(d); PRC § 5097.98). CEQA and other State regulations regarding Native American human remains provide the following procedural requirements to assist in avoiding potential adverse effects on human remains within the contexts of their value to both descendant communities and the scientific community: Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Cultural Resources and Tribal Cultural Resources FirstCarbon Solutions 3.4-15 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\EIR\3 - Draft EIR\26480017 Sec03-04 Cultural-Tribal Cultural Resources.docx • When an initial study identifies the existence or probable likelihood that a project would affect Native American human remains, the lead agency is to contact and work with the appropriate Native American representatives identified through the NAHC to develop an agreement for the treatment and disposal of the human remains and any associated burial items (CEQA Guidelines § 15064.5(d); PRC § 5097.98). • If human remains are accidentally discovered, the County Coroner must be contacted. If the County Coroner determines that the human remains are Native American, the Coroner must contact the NAHC within 24 hours. The NAHC must identify the Most Likely Descendant (MLD) to provide for the opportunity to make recommendations for the treatment and disposal of the human remains and associated burial items. • If the MLD fails to make recommendations within 24 hours of notification or the project applicant rejects the recommendations of the MLD, the Native American human remains and associated burial items must be reburied in a location not subject to future disturbance within the project site (PRC § 5097.98). • If potentially affected human remains or a burial site may have scientific significance, whether or not it has significance to Native Americans or other descendant communities, then under CEQA, the appropriate mitigation of effect may require the recovery of the scientific information of the remains/burial through identification, evaluation, data recovery, analysis, and interpretation (CEQA Guidelines § 15064.5(c)(2)). California Public Resources Code Section 5097.91—Native American Heritage Commission Section 5097.91 of the Public Resources Code established the NAHC, whose duties include the inventory of places of religious or social significance to Native Americans and the identification of known graves and cemeteries of Native Americans on private lands. Under Section 5097.91 of the Public Resources Code, a State policy of noninterference with the free expression or exercise of Native American religion was articulated along with a prohibition of severe or irreparable damage to Native American sanctified cemeteries, places of worship, religious or ceremonial sites or sacred shrines located on public property. Section 5097.98 of the Public Resources Code specifies a protocol to be followed when the NAHC receives notification of a discovery of Native American human remains from a County Coroner. Section 5097.5 defines as a misdemeanor the unauthorized disturbance or removal of archaeological, historic, or paleontological resources located on public lands. California Senate Bill 18—Protection of Tribal Cultural Places SB 18 (Government Code § 65352.3) incorporates the protection of California traditional tribal cultural places into land use planning for cities, counties, and agencies by establishing responsibilities for local governments to contact, refer plans to, and consult with California Native American tribes as part of the adoption or amendment of any general or specific plan proposed on or after March 1, 2005. SB 18 requires public notice to be sent to tribes listed on the NAHC SB 18 Tribal Consultation list within the geographical areas affected by the proposed changes. Tribes must respond to a local government notice within 90 days (unless a shorter time frame has been agreed upon by the tribe), indicating whether they want to consult with the local government. Consultations are for the purpose of preserving or mitigating impacts to places, features, and objects described in Sections 5097.9 and 5097.993 of the Public Resources Code that may be affected by the proposed adoption or amendment to a general or specific plan.

AB 52 formally added the category of “tribal cultural resources” to CEQA and extends the consultation and confidentiality requirements to all projects, rather than just projects subject to SB 18 as discussed above. The parties must consult in good faith, and consultation is deemed concluded when either: (1) no tribe responds and requests consultation within 30 days of receipt of formal notification; or (2) the parties agree to measures to mitigate or avoid a significant effect on a TCR (if such a significant effect exists); or (3) when a party concludes that mutual agreement cannot be reached. Mitigation measures agreed upon during consultation must be recommended for inclusion in the environmental document. AB 52 also identifies mitigation measures that may be considered to avoid significant impacts if there is no agreement on appropriate mitigation. Recommended measures include: • Preservation in place • Protecting the cultural character and integrity of the resource • Protecting the traditional use of the resource • Protecting the confidentiality of the resource • Permanent conservation easements with culturally appropriate management criteria California Public Resources Code Section 21074—Effects on Tribal Cultural Resources AB 52 amended the CEQA statute to identify an additional category of resource to be considered under CEQA, called “tribal cultural resources,” and added Public Resources Code Section 21074, which defines “tribal cultural resources” as follows: (a) “Tribal cultural resources” are either of the following: (1) Sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe that are either of the following: A) Included or determined to be eligible for inclusion in the CRHR. B) Included in a local register of historical resources as defined in subdivision (k) of Section 5020.1. (2) A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Section 5024.1. In applying the criteria set forth in subdivision (c) of Section 5024.1 for the purposes of this paragraph, the lead agency shall consider the significance of the resource to a California Native American tribe.

(c) A historical resource described in Section 21084.1, a unique archaeological resource as defined in subdivision (g) of Section 21083.2, or a “nonunique archaeological resource” as defined in subdivision (h) of Section 21083.2 may also be a tribal cultural resource if it conforms with the criteria of subdivision (a). Health and Safety Code Section 7050.5 (Treatment of Human Remains) Section 7050.5 of the California Health and Safety Code sets forth provisions related to the treatment of human remains. As the Code states, “every person who knowingly mutilates or disinters, wantonly disturbs, or willfully removes any human remains in or from any location other than a dedicated cemetery without authority of law is guilty of a misdemeanor”39 except under circumstances as provided in Section 5097.99 of the Public Resources Code. The regulations also provide guidelines for the treatment of human remains found in locations other than a dedicated cemetery including responsibilities of the Coroner. Public Resources Code Section 5097.98 (Discovery of Human Remains) Section 5097.98 provides protocol for the discovery of human remains. It states that “when the commission receives notification of a discovery of Native American human remains from a County Coroner pursuant to subdivision (c) of Section 7050.5 of the Health and Safety Code, it shall immediately notify persons believed to be most likely descended from the deceased Native American.”40 It also sets forth provisions for descendants’ preferences for treatment of the human remains and what should be done if the commission is unable to identify a descendant.

Contra Costa County Historic Resources Inventory The County maintains a Historic Resource Inventory.41 The most recent version was updated in July 2019 and contains a list of historic resources organized by area. None of the listed resources are located within the project site. 3.4.4 - Impacts and Mitigation Measures Significance Criteria According to CEQA Guidelines Appendix G Environmental Checklist, cultural resources impacts resulting from the implementation of the proposed project would be considered significant if the project would: a) Cause a substantial adverse change in the significance of a historical resource as pursuant to Section 15064.5? b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5? c) Disturb any human remains, including those interred outside of formal cemeteries? d) Cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k)? e) Cause a substantial adverse change in the significance of a tribal cultural resource, defined in Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California Native American tribe, and that is a resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1? 41 Contra Costa County Conservation and Development, Community Development Division. 2019.

The proposed project may have an impact on a historical resource if construction of the proposed project would impair a resource’s eligibility for inclusion in the CRHR. Analysis is based on information collected from record searches at the NWIC, additional archival research, pedestrian surveys, and information from historic architectural assessment of existing properties more than 45 years in age located within the project boundaries. If an identified impact would leave a resource no longer able to convey its significance, meaning that the resource would no longer be eligible for listing in the CRHR, then the proposed project’s impact would be considered a significant adverse change. According to Public Resources Code Section 15126.4(b)(1) (CEQA Guidelines), if a project adheres to the Sphere of Influence standards, the project’s impact “shall generally be considered mitigated below a level of significance and thus is not significant.” The proposed project may have an impact on an archaeological resource or human remains if construction of the proposed project would physically damage or destroy archaeological data or human remains (including those interred outside of formal cemeteries). Analysis is based on information collected from record searches at the NWIC, the additional archival research, and pedestrian surveys. Both direct and indirect effects of project implementation were considered for this analysis. Direct impacts are typically associated with construction and/or ground-disturbing activities, and have the potential to immediately alter, diminish, or destroy all or part of the character and quality of archaeological resources and/or historic architecture. Indirect impacts are typically associated with post-project implementation conditions that have the potential to alter or diminish the historical setting of a cultural resource (generally historic architecture) by introducing visual intrusions on existing historical structures that are considered undesirable. The TCR impact analysis is based on information collected from record searches at the NAHC and information from tribal consultation conducted pursuant to AB 52. Impacts are typically associated with construction and/or ground-disturbing activities that have the potential to immediately alter, diminish, or destroy all or part of the character and quality of Native American artifacts and/or human remains that could be uncovered. Specific Thresholds of Significance For purposes of this analysis, the following thresholds are used to evaluate the significance of cultural resources materials and TCRs impacts resulting from implementation of the proposed project. • Impair a historic resource’s eligibility ability to convey its significance (i.e., affect a resources’ inclusion in the NRHP or CRHR) or not adhere to the Secretary of Interior’s Standards for Rehabilitation. • Physically damage or destroy archaeological data or human remains. Contra Costa County–Oak Road Townhouse Condominiums Project Cultural Resources and Tribal Cultural Resources Draft EIR 3.4-20 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\EIR\3 - Draft EIR\26480017 Sec03-04 Cultural-Tribal Cultural Resources.docx • Impair a tribal cultural resource’s ability to convey its significance as defined by Public Resources Code Section 21074. • Physically damage, destroy, or otherwise adversely impact a site, feature, place, or cultural landscape with cultural value to a California Native American tribe and that is a resource determined by Contra Costa County, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. Impacts Evaluation Historic Resources Impact CUL-1: The proposed project could cause a substantial adverse change in the significance of a historical resource pursuant to Section 15064.5. Construction Archival research identified a total of 15 previously recorded built environment resources within a 0.5-mile radius of the project site. Of these, 14 are historic-age buildings or structures located on the project site (single-family residences, industrial property, unidentified property) that have been previously found ineligible for listing in the NRHP and/or CRHR and they do not qualify as historical resources. No previously recorded historical resources are present within or in close proximity to (within 50 feet of) the project site. The pedestrian survey identified the Palmer School, established in 1939. A review of aerial photographs indicated that some existing on-site buildings and structures date to 1965 or earlier, indicting they are 55 years old or more and above the 50 years age threshold for consideration for listing in the California Register. There are 14 historic-age buildings or structures (single-family residences, industrial property, unidentified property) located on the project site that have been previously found ineligible for listing in the NRHP and/or CRHR, and they do not qualify as historical resources. While unlikely, subsurface construction activities always have the potential to damage or destroy previously undiscovered historic resources such as wood, stone, foundations, and other structural remains; debris-filled wells or privies; and deposits of wood, glass, ceramic, and other refuse, if encountered. This would represent a potentially significant impact related to historic resources. Implementation of Mitigation Measure (MM) CUL-1, which requires an inspection and spot- monitoring by a qualified Archaeologist after clearing and grubbing are complete but before any digging or trenching begin, would reduce potential impacts to historic resources that may be discovered during project construction. MM CUL-1 is also applicable to the off-site improvements that involve digging or trenching, including the installation of sidewalks, curbs, gutters, landscaping, storm drain lines, bioretention swales, extension of waterlines, and new sanitary sewer manholes. If a potential resource is identified, construction would be required to stop until appropriate identification and treatment measures are implemented. Therefore, direct and indirect impacts related to historic resources would be less than significant with mitigation.

No operational impacts would occur. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures MM CUL-1 Archaeological Spot-Monitoring and Halt of Construction Upon Encountering Historical or Archaeological Materials An Archaeologist who meets the Secretary of the Interior’s Professional Qualification Standards for archaeology should inspect the site once grubbing and clearing are complete, and prior to any grading or trenching into previously undisturbed soils. This will be followed by regular periodic or “spot-check” archaeological monitoring as determined by the Archaeologist. If the Archaeologist believes that a reduction in monitoring activities is prudent, then a letter report detailing the rationale for making such a reduction and summarizing the monitoring results shall be provided to the Department of Conservation and Development, Community Development Division (CDD) for concurrence. In the event a potentially significant cultural resource is encountered during subsurface earthwork activities, all construction activities within a 100-foot radius of the find shall cease and workers should avoid altering the materials until an Archaeologist has evaluated the situation. The applicant for the proposed project shall include a standard inadvertent discovery clause in every construction contract to inform contractors of this requirement. Potentially significant cultural resources consist of but are not limited to stone, bone, glass, ceramics, fossils, wood, or shell artifacts, or features including hearths, structural remains, or historic dumpsites. The Archaeologist shall make recommendations concerning appropriate measures that will be implemented to protect the resource, including but not limited to excavation and evaluation of the finds in accordance with Section 15064.5 of the CEQA Guidelines. Any previously undiscovered resources found during construction within the project site shall be recorded on appropriate California Department of Parks and Recreation (DPR) 523 forms and will be submitted to the Department of Conservation and Development, Community Development Division, the Northwest Information Center (NWIC), and the California Office of Historic Preservation (OHP), as required. Level of Significance After Mitigation Less than significant impact. Archaeological Resources Impact CUL-2: The proposed project could cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5. Contra Costa County–Oak Road Townhouse Condominiums Project Cultural Resources and Tribal Cultural Resources Draft EIR 3.4-22 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\EIR\3 - Draft EIR\26480017 Sec03-04 Cultural-Tribal Cultural Resources.docx Construction Records search results from the NWIC indicate that 13 cultural resources have been mapped within a 0.5-mile radius of the project site. One of these is a prehistoric archaeological site and 12 are built environment resources. None of these resources are within or in close proximity to the project site. No archaeological resources have been recorded within the project site. However, the close proximity to the historical alignment of Walnut Creek, the relatively flat topography within the project site, and the occurrence of a nearby prehistoric archaeological site creates a potential for undiscovered prehistoric resources to occur within the project site. Such resources could consist of but are not limited to stone, bone, wood, or shell artifacts or features, including hearths and structural elements. This represents a potentially significant impact related to archaeological resources. Implementation of MM CUL-1 requires inspection and spot-monitoring by a qualified Archaeologist after clearing and grubbing are complete but before any excavation or trenching begin, would reduce potential impacts to archaeological resources that may be discovered during project construction. If a potential resource is identified, construction would be required to stop until appropriate identification and treatment measures are implemented. Therefore, direct and indirect impacts related to archaeological resources would be less than significant with mitigation. Operation Impacts related to a project’s potential to cause a substantial adverse change in the significance of an archaeological resource are limited to construction impacts. No direct or indirect operational impacts related to archaeological resources would occur. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures Implement MM CUL-1. Level of Significance After Mitigation Less than significant impact. Human Remains Impact CUL-3: The proposed project could disturb human remains, including those interred outside of formal cemeteries. Construction No human remains or cemeteries are known to exist within or near the project site. However, there is always the possibility that subsurface construction activities associated with the proposed project, such as trenching and grading, could potentially damage or destroy previously undiscovered human remains. This represents a potentially significant impact related to human remains. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Cultural Resources and Tribal Cultural Resources FirstCarbon Solutions 3.4-23 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\EIR\3 - Draft EIR\26480017 Sec03-04 Cultural-Tribal Cultural Resources.docx However, in the unlikely event human remains are discovered, both within the project site and within the areas proposed for the off-site improvements, implementation of MM CUL-3 would require that work be halted and the County Coroner is called to make a determination as to the nature of the remains and to confirm next steps regarding contacting the NAHC and appropriate tribal representatives. Therefore, with implementation of MM CUL-3 and compliance with CEQA Guidelines, direct and indirect impacts related to disturbance of human remains would be less than significant with mitigation. Operation Impacts related to a project’s potential to disturb human remains are limited to construction impacts. No respective direct or indirect operational impacts related to human remains would occur. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures MM CUL-3 Stop Construction Upon Encountering Human Remains In the event of the accidental discovery or recognition of any human remains, CEQA Guidelines Section 15064.5, Health and Safety Code Section 7050.5, and Public Resources Code Sections 5097.94 and Section 5097.98 shall be followed. If during the course of project construction, there is accidental discovery or recognition of any human remains, the following steps shall be taken: 1. There shall be no further excavation or disturbance within 100 feet of the remains until the County Coroner is contacted to determine whether the remains are Native American and if an investigation of the cause of death is required. If the Coroner determines the remains to be Native American, the Coroner shall contact the Native American Heritage Commission (NAHC) within 24 hours, and the NAHC shall identify the person or persons it believes to be the Most Likely Descendant (MLD) of the deceased Native American. The MLD may make recommendations to the landowner or the person responsible for the excavation work within 48 hours, for means of treating or disposing of, with appropriate dignity, the human remains and any associated grave goods as provided in Public Resources Code Section 5097.98. 2. Where the following conditions occur, the landowner or his or her authorized representative shall rebury the Native American human remains and associated grave goods with appropriate dignity either in accordance with the recommendations of the MLD or on the project site in a location not subject to further subsurface disturbance: • The NAHC is unable to identify an MLD or the MLD failed to make a recommendation within 48 hours after being notified by the NAHC. • The descendant identified fails to make a recommendation. • The landowner or his authorized representative rejects the recommendation of the descendant, and mediation by the NAHC fails to provide measures acceptable to the landowner.

The applicant may develop a plan for treating or disposing of, with appropriate dignity, the human remains and any items associated with Native American Burials with the appropriate Native Americans as identified by the NAHC. Level of Significance After Mitigation Less than significant impact. Significance of Tribal Cultural Resource and Eligibility for California Register Listing Impact CUL-4: The proposed project could cause a substantial adverse change in the significance of a Tribal Cultural Resource that is listed or eligible for listing in the California Register of Historical Resources, or in a local register of historical resources as defined in Public Resources Code Section 5020.1(k). Construction A review of the CRHR, local registers of historic resources, a records search conducted at the NWIC, and an NAHC SLF search failed to identify any listed TCRs that may be adversely affected by the proposed project. Moreover, no tribe requested consultation within the 30-day period established by AB 52. However, if a potential resource is identified, construction would be required to stop until appropriate identification and treatment measures are implemented. Therefore, direct and indirect impacts related to TCRs would be less than significant with implementation MM CUL-1 and MM CUL-3. Operation Impacts related to a project’s potential to cause a substantial adverse change in the significance of a State listed or eligible tribal cultural resource are limited to construction impacts. No respective operational impacts would occur. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures Implement MM CUL-1 and MM CUL-3. Level of Significance After Mitigation Less than significant impact.

Construction On August 13, 2020, ESA contacted the NAHC to NAHC to determine whether any sacred sites are listed on its SLF for the project area. A response was received on August 18, 2020, and indicated that the SLF results failed to indicate the presence of Native American cultural resources in the immediate project area. The NAHC included a list of eight tribal representatives available for consultation. To ensure that all Native American knowledge and concerns over potential TCRs that may be affected by the proposed project are addressed, a letter containing project information and requesting any additional information was sent to each tribal representative on May 11, 2021. On March 9, 2021, the County notified the Wilton Rancheria pursuant to Public Resources Code Section 21080.3.1 that the proposed project may be within a geographic area in which the tribe may be traditionally and culturally affiliated. On March 11, 2021, the Wilton Rancheria responded that it has no concerns regarding the proposed project. However, if a potential resource is identified, construction would be required to stop until appropriate identification and treatment measures are implemented. Therefore, direct and indirect impacts related to TCRs would be less than significant with implementation MM CUL-1 and MM CUL-3. Operation Impacts related to a project’s potential to cause a substantial adverse change in the significance of a State listed or eligible tribal cultural resource are limited to construction impacts. No operational impacts would occur. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures Implement MM CUL-1 and MM CUL-3. Level of Significance After Mitigation Less than significant impact. 3.4.5 - Cumulative Impacts The geographic scope of the cumulative cultural resources analysis is the project vicinity. Cultural resource impacts tend to be localized, because the integrity of any given resource depends on what occurs only in the immediate vicinity around that resource, such as disruption of soils; therefore, in addition to the project site itself, the area near the project site would be the area most affected by project activities (generally within a 0.5-mile radius).

Construction activities associated with development projects in the project vicinity may have the potential to encounter undiscovered cultural resources. These projects would be required to mitigate for impacts through compliance with applicable federal and State laws governing cultural resources. Although there is the possibility that previously undiscovered resources could be encountered by subsurface earthwork activities associated with the cumulative projects, the implementation of construction mitigation measures would ensure that undiscovered cultural resources are not adversely affected by cumulative project-related construction activities, which would prevent the destruction or degradation of potentially significant cultural resources. The implementation of comprehensive mitigation measures for the cumulative projects and the proposed project would result in a less than significant with mitigation cumulative impact related to cultural resources.

This section also evaluates the possible impacts related to energy that could result from implementation of the proposed project. Information in this section is based on project- specific energy calculation outputs included in Appendix B. No comments were received during the Notice of Preparation (NOP) comment period related to energy. 3.5.2 - Existing Setting Energy Basics Energy is generally transmitted in either the form of electricity, measured in kilowatt (kW)1 or megawatt (MW),2 or natural gas, measured in British Thermal Units (BTU) or cubic feet.3 Fuel, such as gasoline or diesel, is measured in gallons or liters. Electricity Electricity is used primarily for lighting, appliances, and other uses associated with the proposed project. Natural Gas Natural gas uses primarily are heating, water heating, and cooking, and is typically associated with commercial and residential uses. Fuel Fuel use is primarily for powering off-road equipment, trucks, and passenger vehicles. Typical fuel types are diesel and gasoline. Electricity Generation, Distribution, and Use State of California The State of California generated approximately 200,475 gigawatt-hours (GWh) of electricity in 2019. Approximately 43 percent of the energy generation is sourced from natural gas, 32.1 percent from renewable sources (i.e., solar, wind, and geothermal), 16.5 percent from large hydroelectric sources, and the remaining 8.4 percent is sourced from coal, nuclear, oil, and other non-renewable sources.4 1 1 kW = 1.000 watts; A watt is a derived unit of power that measure rate of energy conversion. 1 watt is equivalent to work being done at a rate of 1 joule of energy per second. In electrical terms, 1 watt is the power dissipated by a current of 1 ampere flowing across a resistance of 1 volt. 2 1 MW = 1 million watts 3 A unit for quantity of heat that equals 100,000 British thermal units. A British thermal unit is the quantity of heat required to raise the temperature of 1 pound of liquid water 1 degree Fahrenheit at a constant pressure of 1 atmosphere. 4 State of California. 2019.

These entities include investor-owned utilities (IOUs), publicly owned LSEs, rural electric cooperatives, community choice aggregators, and electric service providers.6 Contra Costa County Pacific Gas & Electric Company (PG&E) provides electricity to many of the cities throughout Contra Costa County (County). In April 2018, Marin Clean Energy (MCE) became the primary electricity provider for several of these cities and unincorporated portions of the County.7 Most of the County’s energy is consumed by residential activities (41 percent), followed by major industrial activities (34 percent) and all other nonresidential activities (25 percent).8 Project Site The former Palmer School for Boys and Girls, a private elementary school, operated at the project site from 1939 until its closure due to COVID-19 in June 2020. However, no active school currently exists on the project site and there are no existing residences or other uses within the project site that would consume electricity. PG&E provides electricity to the project site. Natural Gas Generation, Distribution, and Use State of California Natural gas continues to play an important and varied role in California; however, California continues to depend on out-of-state imports for nearly 90 percent of its natural gas supply.9 The State’s net natural gas production for 2019 was approximately 193.9 billion cubic feet, representing a decrease of approximately 4.3 percent from 2018 production.10 In 2018, California consumed a total of 12,666 million U.S. therms of natural gas, or approximately 1,266 trillion BTU,11 with approximately 28.8 percent going directly to electricity generation.12 According to the California Energy Commission’s (CEC) Energy Consumption Database, residential natural gas demand accounted for approximately 34.7 percent of California’s total natural gas demand while nonresidential natural gas demand accounted for approximately 65.3 percent.13 5 United States Energy Information Administration. 2021.

Project Site The former Palmer School for Boys and Girls, a private K–8 school, operated at the project site from 1939 until its closure due to COVID-19 in June 2020. However no active school currently exists on the project site, and there are no existing residences or other uses within the project site that would consume natural gas. Although natural gas for the project site is provided by PG&E,14 the proposed project will be all electric. Fuel Use State of California California is one of the top producers of petroleum in the nation, with drilling operations occurring throughout the State. A network of crude oil pipelines connects production areas to oil refineries in the Los Angeles area, the San Francisco Bay Area, and the Central Valley. California oil refineries also process Alaskan and foreign crude oil received in ports in Los Angeles, Long Beach, and the San Francisco Bay Area. Crude oil production in California and Alaska is in decline, and California refineries have become increasingly dependent on foreign imports.15 Since 2012, foreign suppliers, led by Saudi Arabia, provide over half of the crude oil refined in California.16,17 According to the United States Energy Information Administration (EIA), California’s field production of crude oil has steadily declined since the mid-1980s, totaling approximately 161.5 million barrels in 2019.18 According to the EIA, transportation accounted for nearly 40 percent of California’s total energy demand, amounting to approximately 3,170 trillion BTU in 2018.19 California’s transportation sector, including rail and aviation, consumed roughly 584 million barrels of petroleum fuels in 2018.20 In 2018, petroleum-based fuels were used for approximately 86 percent of the State’s total transportation activity.21 The CEC produces the California Annual Retail Fuel Outlet Report, which is a compilation of gasoline and diesel fuel sales data from across the State available at the county level. 14 Pacific Gas & Electric Company (PG&E). 2014.

The use of these fuels is encouraged through various Statewide regulations and plans, such as the Low Carbon Fuel Standard (LCFS) and Senate Bill (SB) 32. Conventional gasoline and diesel may be replaced, depending on the capability of the vehicle, with transportation fuels including hydrogen, biodiesel, and electricity. Currently, 48 public hydrogen refueling stations exist in California; however, none are in the County.23,24 Currently, nine public biodiesel refueling stations are in California, with none of them in the County.25 Electric Vehicles Electricity can be used to power electric and plug-in hybrid Electric Vehicles (EVs) directly from the power grid. Electricity used to power vehicles is generally provided by the electricity grid and stored in the vehicle’s batteries. Fuel cells are being explored to use electricity generated onboard the vehicle to power electric motors. Currently, California has 12,696 EV charging stations.26 Project Site The former Palmer School for Boys and Girls, a private elementary school, operated at the project site from 1939 until its closure due to COVID-19 in June 2020. However, no active school currently exists on the project site and there are no existing residences or other uses within the project site that would consume fuels. 3.5.3 - Regulatory Framework Federal Energy Independence and Security Act The Energy Policy Act of 2005 created the Renewable Fuel Standard program. The Energy Independence and Security Act of 2007 expanded this program by: • Expanding the Renewable Fuel Standard program to include diesel in addition to gasoline; • Increasing the volume of renewable fuel required to be blended into transportation fuel from 9 billion gallons in 2008 to 36 billion gallons by 2022; • Establishing new categories of renewable fuel, and setting separate volume requirements for each one; and 22 California Energy Commission (CEC). 2019. 2010-2018 CEC-A15 Results and Analysis.

This expanded Renewable Fuel Standard program lays the foundation for achieving substantial reductions of GHG emissions from the use of renewable fuels, reducing the use of imported petroleum, and encouraging the development and expansion of the nation’s renewable fuels sector. Signed on December 19, 2007, the Energy Independence and Security Act (EISA) of 2007 aims to: • Move the United States toward greater energy independence and security. • Increase the production of clean renewable fuels. • Protect consumers. • Increase the efficiency of products, buildings, and vehicles. • Promote research on and deploy GHG capture and storage options. • Improve the energy performance of the federal government. • Increase U.S. energy security, develop renewable fuel production, and improve vehicle fuel economy. EISA reinforces the energy reduction goals for federal agencies put forth in Executive Order 13423, as well as introduces requirements that are more aggressive. The three key provisions enacted are the Corporate Average Fuel Economy Standards, the Renewable Fuel Standard, and the appliance/lighting efficiency standards. The EPA is committed to developing, implementing, and revising both regulations and voluntary programs under the following subtitles in EISA, among others: • Increased Corporate Average Fuel Economy Standards • Federal Vehicle Fleets • Renewable Fuel Standard • Biofuels Infrastructure • Carbon Capture and Sequestration 27 The EPA and National Highway Traffic Safety Administration Light-Duty Vehicle GHG Emission Standards and Corporate Average Fuel Economy Standards Final Rule Congress first passed the Corporate Average Fuel Economy law in 1975 to increase the fuel economy of cars and light duty trucks. The law has become more stringent over time. On May 19, 2009, President Barack Obama put in motion a new national policy to increase fuel economy for all new cars and trucks sold in the United States. On April 1, 2010, the EPA and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) announced a joint final rule 27 United States Environment Protection Agency (EPA). 2019.

The first phase of the national program would apply to passenger cars, light duty trucks, and medium duty passenger vehicles, covering model years 2012 through 2016. They require these vehicles to meet an estimated combined average emissions level of 250 grams of carbon dioxide (CO2) per mile, equivalent to 35.5 miles per gallon if the automobile industry were to meet this CO2 level solely through fuel economy improvements. Together, these standards would cut CO2 emissions by an estimated 960 million metric tons and 1.8 billion barrels of oil over the lifetime of the vehicles sold under the program (model years 2012-2016). The EPA and the NHTSA issued final rules on a second phase joint rulemaking, establishing national standards for light duty vehicles for model years 2017 through 2025 in August 2012.28 The new standards for model years 2017 through 2025 apply to passenger cars, light duty trucks, and medium duty passenger vehicles. The final standards project an average industry fleet wide level of 163 grams/mile of CO2 in model year 2025, which is equivalent to 54.5 miles per gallon (mpg) if achieved exclusively through fuel economy improvements. The EPA and NHTSA issued final rules for the first national standards to reduce GHG emissions and improve fuel efficiency of heavy-duty trucks and buses on September 15, 2011, which became effective November 14, 2011. For combination tractors, the agencies are proposing engine and vehicle standards that began in the 2014 model year and achieve up to a 20 percent reduction in CO2 emissions and fuel consumption by the 2018 model year. For heavy-duty pickup trucks and vans, the agencies are proposing separate gasoline and diesel truck standards, which phase in starting in the 2014 model year and achieve up to a 10 percent reduction for gasoline vehicles, and a 15 percent reduction for diesel vehicles by 2018 model year (12 and 17 percent respectively if accounting for air conditioning leakage). Last, for vocational vehicles, the engine and vehicle standards would achieve up to a 10 percent reduction in fuel consumption and CO2 emissions from the 2014 to 2018 model years. The State of California has received a waiver from the EPA to have separate, stricter Corporate Average Fuel Economy Standards. Although global climate change did not become an international concern until the 1980s, efforts to reduce energy consumption began in California in response to the oil crisis in the 1970s, resulting in the incidental reduction of GHG emissions. In order to manage the State’s energy needs and promote energy efficiency, Assembly Bill (AB) 1575 created the CEC in 1975. State California Assembly Bill 1493: Pavley Regulations and Fuel Efficiency Standards California AB 1493, enacted on July 22, 2002, required the California Air Resources Board (ARB) to develop and adopt regulations that reduce GHGs emitted by passenger vehicles and light duty trucks. Implementation of the regulation was delayed by lawsuits filed by automakers and by the 28 United States Environmental Protection Agency (EPA). 2012.

The EPA subsequently granted the requested waiver in 2009, which the U.S. District Court for the District of Columbia upheld in 2011.29 The standards are to be phased in during the 2009 through 2016 model years. When fully phased in, the near-term (2009–2012) standards will result in an approximately 22 percent reduction compared with the 2002 fleet, and the mid-term (2013–2016) standards will result in about a 30 percent reduction. Amendments to the Low Emission Vehicle (LEV) Program, referred to as LEV III or the Advanced Clean Cars program, incorporated the second phase of implementation for the Pavley Bill. The Advanced Clean Car program combines the control of smog-causing pollutants and GHG emissions into a single coordinated package of requirements for model years 2017 through 2025. The regulation will reduce GHGs from new cars by 34 percent from 2016 levels by 2025. The new rules will reduce pollutants from gasoline and diesel-powered cars, and deliver increasing numbers of zero-emission technologies, such as full battery electric cars, newly emerging plug-in hybrid EV and hydrogen fuel cell cars. The regulations will also ensure adequate fueling infrastructure is available for the increasing numbers of hydrogen fuel cell vehicles planned for deployment in California.30 California Code of Regulations Title 13: Motor Vehicles California Code of Regulations, Title 13: Division 3, Chapter 10, Article 1, Section 2485: Airborne Toxic Control Measure to Limit Diesel-Fueled Commercial Motor Vehicle Idling.31 This measure seeks to reduce public exposure to diesel particulate matter and other air contaminants by establishing idling restrictions, emission standards, and other requirements for heavy-duty diesel engines and alternative idle reduction technologies to limit the idling of diesel-fueled commercial motor vehicles. Any person that owns, operates, or causes to operate any diesel-fueled commercial motor vehicle must not allow a vehicle to idle for more than five consecutive minutes at any location, or operate a diesel-fueled auxiliary power system for greater than five minutes at any location when within 100 feet of a restricted area. California Code of Regulations, Title 13: Division 3, Chapter 9, Article 4.8, Section 2449: General Requirements for In-Use Off-Road Diesel-Fueled Fleets. This measure regulates oxides of nitrogen (NOX), diesel particulate matter (DPM), and other criteria pollutant emissions from in-use, off-road diesel-fueled vehicles. This measure also requires each fleet to meet fleet average requirements or demonstrate that it has met “best available control technology” requirements. Additionally, this measure requires medium and large fleets to have a written idling policy made available to operators of the vehicles, informing them that idling is limited to five consecutive minutes or less. California Senate Bill 1078: Renewable Electricity Standards On September 12, 2002, Governor Gray Davis signed SB 1078, requiring California to generate 20 percent of its electricity from renewable energy by 2017.

On November 17, 2008, Governor Arnold Schwarzenegger signed Executive Order S- 14-08, which established a Renewable Portfolio Standard target for California requiring that all retail sellers of electricity serve 33 percent of their load with renewable energy by 2020. Governor Schwarzenegger also directed the ARB (Executive Order S-21-09) to adopt a regulation by July 31, 2010, requiring the State’s LSE to meet a 33 percent renewable energy target by 2020. The ARB approved the Renewable Electricity Standard on September 23, 2010, by Resolution 10-23. California SB 350: Clean Energy and Pollution Reduction Act In 2015, the State legislature approved, and the Governor signed SB 350, which reaffirmed California’s commitment to reducing its GHG emissions and addressing climate change. Key provisions include an increase in the Renewables Portfolio Standard (RPS), higher energy efficiency requirements for buildings, initial strategies toward a regional electricity grid, and improved infrastructure for EV charging stations. Provisions for a 50 percent reduction in the use of petroleum Statewide were removed from the Bill due to opposition and concern that it would prevent the Bill’s passage. Specifically, SB 350 requires the following to reduce Statewide GHG emissions: • Increase the amount of electricity procured from renewable energy sources from 33 percent to 50 percent by 2030, with interim targets of 40 percent by 2024, and 25 percent by 2027. • Double the energy efficiency in existing buildings by 2030. This target will be achieved through the California Public Utility Commission, the CEC, and local publicly owned utilities. • Reorganize the Independent System Operator (ISO) to develop more regional electrified transmission markets and to improve accessibility in these markets, which will facilitate the growth of renewable energy markets in the western United States.32 California Code of Regulations Title 24 Part 6 (Energy Efficiency Standards for Residential and Nonresidential Buildings) California Code of Regulations Title 24 Part 6 (California’s Energy Efficiency Standards for Residential and Nonresidential Buildings) was first adopted in 1978 in response to a legislative mandate to reduce California’s energy consumption. The standards are updated periodically to allow consideration and possible incorporation of new energy efficient technologies and methods. Energy efficient buildings require less electricity; therefore, increased energy efficiency reduces fossil fuel consumption and decreases GHG emissions. The 2016 Building Energy Efficiency Standards went into effect on January 1, 2017.33 The 2019 Building Energy Efficiency Standards are scheduled to go into effect on January 1, 2020. Part 11 (California Green Building Standards Code) California Code of Regulations Title 24, Part 11, is a comprehensive and uniform regulatory code for all residential, commercial, and school buildings that went in effect January 1, 2011.

The code recognizes that many jurisdictions have existing construction and demolition ordinances and defers to them as the ruling guidance if they provide a minimum 50 percent diversion requirement. The code also provides exemptions for areas not served by construction and demolition recycling infrastructure. The California Building Code provides the minimum standard that buildings must meet to be certified for occupancy, which is enforced by the local building or planning department with jurisdiction over the building. California Public Utilities Code The California Public Utilities Commission (CPUC) regulates privately owned telecommunication, electric, natural gas, water, railroad, rail transit, and passenger transportation companies. It is the responsibility of the CPUC to (1) assure California utility customers receive safe, reliable utility service at reasonable rates; (2) protect utility customers from fraud; and (3) promote a healthy California economy. The Public Utilities Code, adopted by the legislature, defines the jurisdiction of the CPUC. Local Contra Costa County General Plan Conservation Element The County does not fully utilize its renewable energy sources in the forms of wind energy and solar power. Chapter 8, the Conservation Element of the Contra Costa County General Plan (General Plan), contains the following goals and implementation measures pertaining to the County’s renewable energy resources.35 Goal 8-K To encourage the use of renewable resources where they are compatible with the maintenance of environmental quality. Goal 8-L To reduce energy use in the County to avoid risks of air pollution and energy shortages which could prevent orderly development.

Would the project: a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation? b) Conflict with or obstruct a State or local plan for renewable energy or energy efficiency? Approach to Analysis For the purposes of this Draft Environmental Impact Report (Draft EIR), the approach to analysis for energy use is based on 2021 CEQA Guidelines Appendix F (Energy Conservation), which focuses on conserving energy through the wise and efficient use of energy. Estimates of energy consumption associated with the proposed project are based, in part, on information provided by the California Emissions Estimator Model (CalEEMod) output included in this Draft EIR as Appendix B. CalEEMod contains energy intensity rates for the various land uses selected; see Section 3.7, Greenhouse Gas Emissions, Approach to Analysis, for detailed information regarding how project-specific energy estimates are determined. Renewable Energy/Energy Efficiency Plan Consistency Determination Methodology The proposed project is assessed for whether it would conflict with or obstruct a State or local plan for renewable energy or energy efficiency. To achieve this, the proposed project is assessed for consistency with State goals and plans related to energy efficiency and renewable energy. 37 Contra Costa County. 2015.

Impact Evaluation Energy Use Impact ENER-1: The proposed project would not result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or operation. A significant impact would occur if the proposed project would result in the inefficient, wasteful, or unnecessary use of energy. Construction For the purposes of this GHG analysis, construction of the proposed project was assumed to begin in September 2022 and continue through November 2023. If the construction schedule moves to later years, construction energy demand would likely decrease because of improvements in technology and more stringent regulatory requirements as older, less efficient equipment is replaced by newer and cleaner equipment. The proposed project would require demolition, site preparation, grading, building construction, architectural coating, and paving activities. Project construction would require energy for the manufacture and transportation of building materials, preparation of the site (e.g., demolition, site clearing, and grading), and the actual construction of the building. Petroleum-based fuels such as diesel fuel and gasoline would be the primary sources of energy for these tasks. Much of the energy consumption are likely to occur in the first year when demolition, site preparation and grading activities occur. The types of on-site equipment used during construction of the proposed project could include gasoline- and diesel-powered construction and transportation equipment, including trucks, bulldozers, frontend loaders, forklifts, and cranes. Construction equipment is estimated to consume a total of 36,941 gallons of diesel fuel over the entire construction duration (Appendix B). Fuel use associated with construction vehicle trips generated by the proposed project was also estimated; trips include construction worker trips, haul truck trips for material transport, and vendor trips for construction material deliveries. Fuel use from these vehicles traveling to the project site was based on (1) the projected number of trips the proposed project would generate during construction, (2) average trip distances by trip type, and (3) fuel efficiencies estimated in the ARB Emissions Factors model (EMFAC) mobile source emission model.

In total, the proposed project is estimated to generate 498,347 Vehicle Miles Traveled (VMT) and a combined 23,042 gallons of gasoline and diesel for vehicle travel during construction. Other equipment could include construction lighting, field services (office trailers), and electrically driven equipment such as pumps and other tools. Singlewide mobile office trailers, which are commonly used in construction staging areas, generally range in size from 160 square feet to 720 square feet. A typical 720-square-foot office trailer would consume approximately 15,722 kilowatt- hours (kWh) during the 1.2-year construction phase (Appendix B). The proposed project’s construction is not anticipated to result in unusually high energy use. Limitations on idling of vehicles and equipment and requirements that equipment be properly maintained would result in fuel savings. Similarly, compliance with State regulations would limit idling from both on-road and off-road diesel-powered equipment and are enforced by the ARB. Additionally, the overall construction schedule and process is already designed to be efficient in order to avoid excess monetary costs. For example, equipment and fuel are not typically used wastefully due to the added expense associated with renting the equipment, maintaining it, and fueling it. Therefore, the opportunities for future efficiency gains during construction are limited. Therefore, it is anticipated that the construction phase of the proposed project would not result in wasteful, inefficient, and unnecessary consumption of energy. Construction-related energy impacts would be less than significant. Operation The proposed project would consume energy as part of building operations and transportation activities. Project energy consumption is summarized in Table 3.5-1. Table 3.5-1: Annual Project Energy Consumption Energy Consumption Activity Annual Consumption Electricity Consumption 635,439 kWh/year Natural Gas Consumption 0 kBTU/year Total Fuel Consumption 63,021 gallons of Diesel and Gasoline Notes: kWh = kilowatt-hour kBTU = kilo-British Thermal Unit VMT = Vehicle Miles Traveled Operational fuel consumption based on EMFAC2021 Emissions Inventory, Vehicle Classification (Fleet Mix) EMFAC2007 Categories. The calculations are for the year 2024 when the proposed project will be fully operational and for the County, where the proposed project is located (Appendix B). Unmitigated operation of the proposed project would consume an estimated 635,439 kWh of electricity and an estimated 0 kBTU of natural gas on an annual basis. The proposed project’s buildings would be designed and constructed in accordance with the County’s latest adopted energy efficiency standards, which are based on the State’s Building Energy Efficiency Standards. These are Contra Costa County—Oak Road Townhouse Condominiums Project Draft EIR Energy FirstCarbon Solutions 3.5-13 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-05 Energy.docx widely regarded as the most advanced building energy efficiency standards and compliance would ensure that building energy consumption would not be wasteful, inefficient, or unnecessary. The proposed project is designed be all electric construction in the new homes with no natural gas provided. Each home will have roof-top solar panels. The number and orientation of the panels will vary from unit to unit. At a minimum, the solar panels would off-set the increased electricity demand for appliances that may have been traditional. In total, the proposed project would consume 63,021 gallons of gasoline and diesel per year starting in 2023. The majority of operational fuel consumption would be from employee vehicle emissions, which would be regulated by State and federal policies and could not be feasibly mitigated by the proposed project or County. The proposed project is located in proximity to transit in order to reduce VMT. Bus transit services in the vicinity of the project site are provided by County Connection. The site is served by several County Connection bus routes: 7, 9, 11, 14, 15, and 311. The closest bus stop to the project site is located at Oak Road and Walden Park, approximately 970 feet south of the project site. There are sidewalks on Oak Road that provide connectivity to the bus stop. The Bay Area Rapid Transit (BART) is a regional rail transit service that operates within the County and provides connections to Alameda, San Francisco, and San Mateo Counties. The Pleasant Hill/Contra Costa Center BART station is located approximately 0.35 mile from the project site. Currently, there are no existing bike lanes on Jones Road. The Iron Horse Regional Trail, located approximately 1,500 feet east of the project site, provides a multiuse bicycle/pedestrian pathway, which access to the Pleasant Hill BART station. There is also another bicycle/pedestrian trail, Contra Costa Canal Trail, located approximately 450-600 feet south of the project site, which crosses Oak Road and Jones Road. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. The proposed project would not affect existing and planned bicycle facilities. The project also proposes to include a bike repair space on-site. As a result, the proposed project is located near regional and local roadway. Transportation fuel consumption would not be wasteful, inefficient, or unnecessary. Impacts would be less than significant. Level of Significance Less than significant impact. Energy Efficiency and Renewable Energy Standards Consistency Impact ENER-2: The proposed project would not conflict with or obstruct a State or local plan for renewable energy or energy efficiency. For this impact discussion, a significant impact would occur if the proposed project would conflict with or obstruct a State or local plan for renewable energy or energy efficiency. The County has developed a CAP that contains several energy efficiency goals and measures that would relate to the proposed project. In addition, the County’s General Plan Conservation Element contains several energy efficiency goals that would relate to the proposed project. This analysis is based on consistency with State goals and plans related to energy efficiency and renewable energy as well as relevant goals and measures contained in the County’s CAP and General Plan Conservation Element.

These standards include minimum energy efficiency requirements related to building envelope, mechanical systems (e.g., heating, ventilation, and air conditioning [HVAC] and water heating systems), and indoor and outdoor lighting. The incorporation of the Title 24 standards into the design of the proposed project would ensure that the proposed project would not result in the use of energy in a wasteful manner. Furthermore, the proposed roof- top solar panels would off-set the increased electricity demand for appliances that may have been traditionally. The General Plan Conservation Element contains policies related to energy conservation that are relevant to the proposed project. Compliance with Title 24 standards would ensure that the proposed project would not conflict with any of the Conservation Element energy conservation policies related to the proposed project’s building envelope, mechanical systems, and indoor and outdoor lighting. Moreover, as previously illustrated in Section 3.7, Greenhouse Gas Emissions, Table 3.7-6, Contra Costa County Climate Action Plan Consistency, the proposed project would be consistent with the GHG reduction measures contained in the County’s CAP, which are closely related to and include energy efficiency measures. The proposed project would comply with existing State energy standards and be consistent with the energy efficiency goals and measures contained in the County’s General Plan Conservation Element and CAP. As such, the proposed project would not conflict with State or local renewable or energy efficiency objectives. Impacts would be less than significant. Level of Significance Less than significant impact. 3.5.5 - Cumulative Impacts The geographic scope of the cumulative energy analysis is the portion of PG&E’s service area that covers incorporated and unincorporated County. Cumulative projects considered as part of this cumulative analysis include the proposed project and other cumulative projects identified in Chapter 3, Environmental Impact Analysis, Table 3-1. Electricity and Natural Gas Cumulative projects would be required to comply with Title 24 Building Energy Efficiency Standards and the California Green Building Standards Code (CALGreen). The cumulative buildings would be designed in accordance with Title 24, California’s Energy Efficiency Standards for Residential Buildings as applicable. These standards include minimum energy efficiency requirements related to building envelope, mechanical systems (e.g., HVAC and water heating systems), and indoor and outdoor lighting. Future development would also be required to meet even more stringent energy efficiency requirements through local and Statewide policy, such as Title 24, Part 6, which would require that newly constructed residential homes include on-site photovoltaic solar systems, with some exceptions. Furthermore, PG&E, which supplies electricity to the project area, would be required by SB 100 to incrementally increase the proportion of renewable electricity generation supplying its in-state retail sales until it reaches 100 percent carbon-free electricity generation by Contra Costa County—Oak Road Townhouse Condominiums Project Draft EIR Energy FirstCarbon Solutions 3.5-15 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-05 Energy.docx 2045. Nonetheless, the incorporation of these regulations into the design of the cumulative projects, including the proposed project, would ensure that the cumulative projects would not result in the inefficient, unnecessary, or wasteful consumption of electricity or natural gas, and impacts would be less than significant. The proposed project’s energy use would be limited to that which is necessary for the construction and operation of the proposed project. The proposed project would comply with Statewide and local policies pertaining to energy efficiency and would reasonably pursue greater energy efficiencies in its operation in the interest of reducing operating costs. As such, the proposed project’s incremental contribution to potential cumulative impacts would be less than significant related to energy consumption in the form of electricity and natural gas. Fuel Cumulative projects would be required to comply with California Code of Regulations Title 13, Sections 2449(d)(3) and 2485, that limit idling from both on-road and off-road diesel-powered equipment and are enforced by the ARB. Additionally, various federal and State regulations, including the LCFS, Pavley Clean Car Standards, and LEV Program, would serve to reduce the transportation fuel demand of cumulative projects. Compliance with these regulations by the cumulative projects, including the proposed project, would ensure that the cumulative projects would not result in the inefficient, unnecessary, or wasteful consumption of fuel and the cumulative impact would be less than significant. Therefore, the proposed project would have a less than cumulatively considerable impact with respect to significant cumulative impacts related to the wasteful or inefficient use of energy. Level of Cumulative Significance Less than significant impact.

This section also evaluates the possible impacts related to geology and soils that could result from implementation of the proposed project. Information included in this section is based on the Contra Costa County General Plan (General Plan) and the United States Geological Survey (USGS). Additional resources include the Preliminary Geotechnical Exploration prepared by ENGEO; Geologic Peer Review/30-Day Comments prepared by the County’s Geologist, Darwin Myers Associates; and the Paleontological Records Search prepared by Consulting Paleontologist, Kenneth Finger, PhD, all of which are included in Appendix E. During the Notice of Preparation (NOP) comment period, the following comments were received related to the proposed project regarding geology and soils: • Concern that demolition and construction activities could result in foundation damage to neighboring homes. • Concern that the small setback would impact to foundations of neighboring homes. • Concern that the proposed project would impact the foundations of neighboring homes. • Concern of potential substance foundation exterior cracks that may affect neighboring properties. 3.6.2 - Environmental Setting Geologic Setting Contra Costa County Contra Costa County (County) is in the Coast Ranges geomorphic province of California. The Coast Ranges have experienced a complex geological history characterized by Late Tertiary folding and faulting that has resulted in a series of northwest-trending mountain ranges and intervening valleys. Bedrock in the Coast Ranges consists of igneous, metamorphic, and sedimentary rocks that range in age from Jurassic to Pleistocene. The present physiography and geology of the Coast Ranges are the result of deformation and deposition along the tectonic boundary between the North American plate and the Pacific plate. Plate boundary fault movements are largely concentrated along the well- known fault zones in the area, which include the San Andreas, Hayward, and Calaveras Faults, as well as other lesser-order faults. Several northwest-trending fault systems dominate the geology of the County, dividing it into large blocks of rock. For example, bounding the Briones Hills is the Hayward Fault on the west and elements of the Franklin-Calaveras fault system on the east. Within a particular block the rock sequence consists of: (1) a basement complex of broken and jumbled pre-Tertiary sedimentary, igneous, and metamorphic rocks; (2) a section of younger Tertiary sedimentary rocks and some volcanic rocks (flows and tuffs) that locally intertongue with, and overlie the sedimentary section; Contra Costa County–Oak Road Townhouse Condominiums Project Geology and Soils Draft EIR 3.6-2 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-06 Geology.docx and (3) surficial deposits including stream alluvium, colluvium (slopewash deposits at the foot of steeper slopes), slides, alluvial fans, and Bay Plain deposits.1 Project Site The project site is located within the central portion of the County and is relatively flat (approximately 90-95 feet above mean sea level). The project site is located within an area mapped as "alluvial fan and fluvial deposits of Pleistocene age" (Qpaf). Alluvial fan deposits are deposits of Pleistocene age and tend to be brown, dense, gravelly, and clayey sand that fines upward to sandy clay. All Qpaf deposits can be related to modern stream courses, and can be distinguished from younger alluvial deposits by higher topographic position, greater degree of dissection, and stronger soil profile development. They are less permeable than Holocene deposits.2 Regional geologic mapping indicates that the project site is underlain by alluvial gravel. The Preliminary Geotechnical Exploration report states that the alluvium may consist of moderately to highly expansive clay to sandy clay.3 Existing Soils Corrosive soils are a geologic hazard, because they react with concrete and ferrous metals, which can cause damage to foundations and buried pipelines. Expansive soils are a geologic hazard, because an increase in soil volume can exert forces on structures and, thus, damage building foundations, walls, and floors. In general, areas are susceptible to differential settlement if underlain by compressible sediments, such as poorly engineered artificial fill or loose unconsolidated alluvial sediments. When these soils dry out and shrink, structural damage can occur. Contra Costa County The United States Department of Agriculture (USDA) Natural Resource Conservation Service (NRCS) has characterized the majority of native, undisturbed soils in the County according to three soil associations: (1) nearly level to strongly sloping, somewhat excessively drained to very poorly drained soils on valley fill, basins, low terraces, flood plains, and alluvial fans; (2) nearly level, poorly drained and very poorly drained soils on the Delta, flood plains, and saltwater marshes and tidal flats; and (3) nearly level to very steep, moderately well drained to excessively drained soils on terraces and mountainous uplands.4 Project Site According to the Soil Survey of Contra Costa County, the soil series mapped on the site is Clear Lake clay (Cc, 0-2 percent slopes). Permeability is slow and the available water holding capacity is 8 to 10 inches. The typical soils profile is 60 inches deep. The A horizon extends from the ground surface to a depth of 30 inches below the ground surface, and is described as a dark gray, very dark gray or black clay. The ACca horizon extends from 30 to 46 inches below ground surface (bgs). It is a dark gray or very dark gray clay. During the summer desiccation cracks 0.5 to 2 inches wide extend to the C 1 Contra Costa County Department of Conservation and Development. 2005.

The C horizon, which extends from 46 to 60 inches bgs is olive, light olive brown or grayish brown and is mottled in places. It is a clay loam, silty clay loam or light clay, clay loam. With regard to engineering properties, the Clear Lake clay is highly expansive and very highly corrosive.5 As part of the Preliminary Geotechnical Exploration, three Core Penetration Test (CPT) probes were extended to at the project site to depths of approximately 78 feet below the ground surface. Two CPTs and one Seismic Cone Penetration Test (SCPT). Alluvial deposits were found in all three borings, and the granular materials in the upper 40 feet appeared to be discontinuous layers at different elevations across the site. Between 40 and 50 feet bgs, a dense to very dense sand and gravelly sand layer was penetrated in all three borings. The native material encountered in the first CPT (1-CPT1) probe was primarily composed of layers between approximately 1 and 12 feet thick of medium-dense to loose sand and medium stiff to very soft silt-like and clay-like material. A medium-dense to very dense sand layer was found between 18 and 24 feet bgs, and another dense sand bed was encountered at approximately 48 feet bgs. The material encountered in the SCPT (1-SCPT2) probe was mostly composed of discontinuous layers up to 6 feet in thickness of medium stiff to very soft silty and clayey mixtures with interbedded pockets of loose to very dense sand deposits. A lens of dense to very dense sand was found between depths of 41 and 49 feet bgs. The native material found in the upper 40 feet of the third CPT (1-CPT3) probe was primarily a continuous deposit of soft to very soft silty clay and clayey silt. A lens of dense to very dense sand and gravelly sand was found between depths of 41 and 49 feet bgs. Ground water was encountered at a depth between 10.6 feet at 1-CPT3 and 18.8 feet at 1-CPT1. Fluctuations in the level of groundwater may occur due to variations in rainfall, irrigation practice, and other factors not evident at the time measurements were made. Future irrigation may cause an overall rise in groundwater levels. Seismicity The term seismicity describes the effects of seismic waves that radiate from an earthquake fault in motion. While most of the energy released during an earthquake results in the permanent displacement of the ground, as much as 10 percent of the energy may dissipate immediately in the form of seismic waves. Seismicity can result in seismic-related hazards such as fault rupture, ground shaking, and liquefaction. Faults form in rocks when stresses overcome the internal strength of the rock, and fault rupture occurs when movement on a fault breaks through to the surface and can result in damage to infrastructure and persons. Ground movement during an earthquake can vary depending on the overall magnitude, distance to the fault, focus of earthquake energy, and type of geologic material. The composition of underlying soils, even those relatively distant from faults, can intensify ground shaking. Strong ground shaking from an earthquake can result in damage, with 5 Darwin Myers Associates. 2021.

Liquefaction occurs when an earthquake causes ground shaking resulting in saturated soil to lose shear strength, deform, and function like a liquid. When liquefaction occurs, it can result in ground failure that can result in damage to roads, pipelines, and buildings. Contra Costa County Area The County is within an area of high seismicity (Exhibit 3.6-1); more than 10 severe earthquakes have affected the San Francisco Bay Region during the recent historic time.6 Six major Bay Area earthquakes have occurred since 1800 that affected the County, and at least two of the faults that produced them run through or into the County. These earthquakes and the originating faults include the 1836 and 1868 earthquakes on the Hayward Fault, and the 1861 earthquake on the Calaveras Fault. Two earthquakes, in 1838 and 1906, originated on the San Andreas Fault, west of the County near San Francisco or to the south, while one earthquake (with two major shocks) that caused some damage in the County occurred in 1872 and was centered north of the County in the Vacaville- Winters area of Solano County.7 These latter events likely occurred on a thrust fault and are not known to have been accompanied by surface fault rupture. A smaller earthquake, centered near Collinsville in Solano County on a fault of uncertain identity, occurred in 1889. The Contra Costa County Department of Conservation and Development developed an earthquake probability estimate for faults that may affect the County, shown in Table 3.6-1 (Table 10-4 of the General Plan). This information predicts that structures built in the County are likely to experience a severely damaging earthquake during their useful life.8 Table 3.6-1: Approximate Probability of Occurrence of Earthquakes on Selected Bay Area Faults (50-year Period) Causative Fault Magnitude Approximate Probability of Occurrence (over a 50-year period) San Andreas Fault 7.0–8.0 Likely1 8.0–8.5 Intermediate2 Hayward Fault 6.0–7.0 Likely 7.0–7.5 Intermediate Calaveras Fault 6.0–7.0 Likely 7.0–7.5 Intermediate-Low3 Concord Fault 5.0–6.0 Likely 6.0–7.0 Intermediate-Low Antioch Fault 5.0–6.0 Likely 6.0–7.0 Intermediate-Low 6 Contra Costa County Department of Conservation and Development. 2005.

The nearest fault that is considered active by California Geological Survey (CGS) is the northwest-trending Concord fault, which passes approximately 3 miles northeast of the project site (Exhibit 3.6-1).9 An active fault is defined by the CGS as one that has had surface displacement within Holocene time.10 The recently active and potentially active traces of the Calaveras and Hayward faults pass approximately 6 and 10.5 miles south and southwest of the site, respectively. The site is not located within a currently designated Alquist-Priolo Earthquake Fault Zone and no known surface expression of active faults are believed to exist within the site. Fault rupture through the site, therefore, is not anticipated.11 Slope Disturbance Slope disturbance from long-term geologic cycle of uplift, mass wasting, intense precipitation or wind, and gravity can result in slope failure in the form of mudslides and rock fall. Mass wasting refers to a variety of erosional processes from gradual downhill soil creep to mudslides, debris flows, landslides, and rock fall–processes that are commonly triggered by intense precipitation or wind, which varies according to climate shifts. Often, various forms of mass wasting are grouped together as landslides, which are generally used to describe the downhill movement of rock and soil. Soil creep is a long-term, gradual downhill migration of soil under the influence of gravity and is generally on the order of a fraction of an inch per year. These soils can creep away downslope sides of foundations and reduce lateral support. Liquefaction is another earthquake hazard that can result in slope disturbance. Liquefaction is a transformation of soil from a solid to a liquefied state during which saturated soil temporarily loses strength resulting from the buildup of excess pore water pressure. Soil susceptible to liquefaction includes loose to medium-dense sand and gravel, low-plasticity silt, and some low-plasticity clay deposits. Five kinds of ground failure commonly result from liquefaction: lateral spread, flow failure, ground oscillation, differential settlement, and loss of bearing strength.12 9 Darwin Myers Associates. 2021.

Slopes may suffer landslides, slumping, soil slips, and rockslides. Reclaimed wetlands, whether filled or not, experience amplified lateral and vertical movements, which can be damaging to structures, utilities, and transportation routes and facilities. The General Plan recognizes that major slope areas more than 26 percent are “not readily developable” and “undevelopable,” recognizing the cost and engineering difficulties of grading steep slopes as well as their inherent unsuitability.13 Figure 10-6 of the General Plan shows Landslide Hazards in the County. Project Site The project site is relatively flat, with no slopes or varied topography that could be susceptible to slope failure, landslides, or soil creep. According to Figure 10-6 of the General Plan, the project site is not located on a site susceptible to landslides or an area where landslides previously occurred,14 and there are no landslide deposits within 1 mile of the project site.15 Figure 10-5 of the General Plan Safety Element indicates that the project site contains two classifications related to liquefaction potential: the northeastern half of the site is classified “Generally High” while the southeastern half of the site is classified “Generally Moderate to Low.” The Preliminary Geotechnical Exploration estimates that a maximum of 4.75 inches of total liquefaction-induced settlement may occur during a maximum considered event earthquake.16 This amount of total liquefaction-induced settlement corresponds to less than 2.5 inches of differential settlement over a horizontal distance of 40 feet. The report states that this amount of differential settlement can be accommodated by the structural engineer in the foundation design.17 An investigation would be needed to determine whether liquefiable sands are present and to provide stabilization measures where liquefiable sands are confirmed.18 Paleontological Resources No known paleontological resources are located within the project site boundaries. The surface area of the project site consists of Holocene alluvium, which is too young to contain fossils. The 0.5-mile search area around the project site boundary also contains only Holocene alluvium. Just outside the search area are late to middle Miocene Monterey Formation shale and sandstone, and the Paleocene Martinez Formation, which are potentially fossiliferous. The absence of Pleistocene or older deposits in the search area suggests that any potential paleontological resources underlying 13 Contra Costa County Department of Conservation and Development. 2005.

In establishing the NEHRP, Congress recognized that earthquake-related losses could be reduced through improved design and construction methods and practices, land use controls and redevelopment, prediction techniques and early warning systems, coordinated emergency preparedness plans, and public education and involvement programs. The four basic goals remain unchanged: • Develop effective practices and policies for earthquake loss reduction and accelerate their implementation. • Improve techniques for reducing earthquake vulnerabilities of facilities and systems. • Improve earthquake hazards identification and risk assessment methods, and their use. • Improve the understanding of earthquakes and their effects. Several key federal agencies contribute to earthquake mitigation efforts. There are four primary NEHRP agencies: • National Institute of Standards and Technology of the Department of Commerce • National Science Foundation • United States Geological Survey of the Department of the Interior • Federal Emergency Management Agency (FEMA) of the Department of Homeland Security Implementation of NEHRP priorities is accomplished primarily through original research, publications, and recommendations to assist and guide State, regional, and local agencies in the development of plans and policies to promote safety and emergency planning. National Pollutant Discharge Elimination System The National Pollutant Discharge Elimination System (NPDES) permit program, authorized by Section 402(p) of the federal Clean Water Act, controls water pollution by regulating point sources, such as construction sites and industrial operations that discharge pollutants into waters of the United States. A Storm Water Pollution Prevention Plan (SWPPP) is required to control discharges from a project site, including soil erosion, to protect waterways. A SWPPP describes the measures or practices to control discharges during both the construction and operational phases of the project.

Society of Vertebrate Paleontology Guidelines The Society of Vertebrate Paleontology (SVP), a national scientific organization of professional Vertebrate Paleontologists, has established standard guidelines that outline acceptable professional practices in the conduct of paleontological resource assessments and surveys, monitoring and mitigation, data and fossil recovery, sampling procedures, specimen preparation, analysis, and curation. Most practicing professional Paleontologists in the nation adhere to the SVP’s assessment, mitigation, and monitoring requirements, as specifically spelled out in its standard guidelines.20 State Regulations Alquist-Priolo Earthquake Fault Zoning Act The Alquist-Priolo Earthquake Fault Zoning Act (Public Resources Code [PRC] §§ 2621 to 2630) was passed in 1972 to provide a Statewide mechanism for reducing the hazard of surface fault rupture to structures used for human occupancy. The main purpose of the Act is to prevent the siting of buildings used for human occupancy across the traces of active faults. It should be noted that the Act addresses the potential hazard of surface fault rupture and is not directed toward other earthquake hazards, such as seismically induced ground shaking or landslides. The law requires the State Geologist to identify regulatory zones (known as Earthquake Fault Zones or Alquist-Priolo Zones) around the surface traces of active faults, and to depict these zones on topographic base maps, typically at a scale of 1 inch to 2,000 feet. Earthquake Fault Zones vary in width, although they are often 0.75-mile wide. Once published, the maps are distributed to the affected cities, counties, and State agencies for their use in planning and controlling new or renewed construction. Except for single-family wood-frame and steel-frame dwellings that are not part of a larger development (i.e., four units or more), local agencies are required to regulate development within the mapped zones. In general, construction within 50 feet of an active fault zone is prohibited. Seismic Hazards Mapping Act The Seismic Hazards Mapping Act (PRC §§ 2690–2699.6), which was passed in 1990, addresses earthquake hazards other than surface fault rupture. These hazards include strong ground shaking, earthquake-induced landslides, liquefaction, or other ground failures. Much like the Alquist-Priolo Earthquake Fault Zoning Act discussed above, these seismic hazard zones are mapped by the State Geologist to assist local government in the land use planning process. The Act states, “it is necessary to identify and map seismic hazard zones in order for cities and counties to adequately prepare the safety element of their general plans and to encourage land use management policies and regulations to reduce and mitigate those hazards to protect public health and safety.” The Act also states, “cities and counties shall require, prior to the approval of a project located in a seismic hazard zone, a geotechnical report defining and delineating any seismic hazard.” 20 The Society of Vertebrate Paleontology. 2010.

Where no other building codes apply, Chapter 29 regulates excavation, foundations, and retaining walls. The California Building Standards Code (CBC) applies to building design and construction in the State and is based on the federal Uniform Building Code (UBC) used widely throughout the country (generally adopted on a state-by-state or district-by-district basis). The CBC has been modified for California conditions with more detailed and/or more stringent regulations. The State earthquake protection law (California Health and Safety Code § 19100 et seq.) requires that structures be designed to resist stresses produced by lateral forces caused by wind and earthquakes. Specific minimum seismic safety and structural design requirements are set forth in Chapter 16 of the CBC. The CBC identifies seismic factors that must be considered in structural design. Chapter 18 of the CBC regulates the excavation of foundations and retaining walls, and Appendix Chapter A33 regulates grading activities, including drainage and erosion control and construction on unstable soils, such as expansive soils and areas subject to liquefaction. The CBC contains specific requirements for seismic safety, excavation, foundations, retaining walls, and site demolition. It also regulates grading activities, including drainage and erosion control (Chapter 18, Appendix J). The 2019 CBC has been adopted by the County through Chapter 74-2 of the Contra Costa County Ordinance Code. Local Regulations Contra Costa County General Plan The General Plan serves as the overall guiding policy document for the County. The following is a list of General Plan goals and policies most pertinent to the proposed project with respect to geology and soils. General Plan Safety Element Goal 10-A To protect human life and reduce the potential for serious injuries from earthquakes; and to reduce the risks of property losses from seismic disturbances, which could have severe economic and social consequences for the County as a whole. Goal 10-B To reduce to a practical minimum injuries and health risks resulting from the effects of earthquake ground shaking on structures, facilities, and utilities. Goal 10-C To protect persons and property from the life-threatening, structurally, and financially disastrous effects of ground rupture and fault creep on active faults, and to reduce structural distress caused by soil and rock weakness due to geologic faults. Goal 10-D To reduce to a practical minimum the potential for life loss, injury, and economic loss due to liquefaction-induced ground failure, levee failure, large lateral land movements toward bodies of water, and consequent flooding; and to mitigate the lesser consequences of liquefaction.

Policy 10-13 In areas where active or inactive earthquake faults have been identified, the location and/or design of any proposed buildings, facilities, or other development shall be modified to mitigate possible danger from fault rupture or creep. Policy 10-14 Preparation of a geologic report shall be required as a prerequisite before authorization of public capital expenditures or private development projects in areas of known or suspected faulting. Policy 10-18 This General Plan shall discourage urban or suburban development in areas susceptible to high liquefaction dangers and where appropriate subject to the policies in 10-20 below, unless satisfactory mitigation measures can be provided, while recognizing that there are low intensity uses such as water-related recreation and agricultural uses that are appropriate in such areas. Policy 10-19 To the extent practicable, the construction of critical facilities, structures involving high occupancies, and public facilities shall not be sited in areas identified as having a high liquefaction potential, or in areas underlain by deposits classified as having a high liquefaction potential. Policy 10-20 Any structures permitted in areas of high liquefaction danger shall be sited, designed, and constructed to minimize the dangers from damage due to earthquake-induced liquefaction. Policy 10-21 Approvals to allow the construction of public and private development projects in areas of high liquefaction potential shall be contingent on geologic and engineering studies which define and delineate potentially hazardous geologic and/or soils conditions, recommend means of mitigating these adverse conditions; and on proper implementation of the mitigation measures. Contra Costa County Ordinance Code Building and Construction Chapter 74-2 of the Contra Costa County Ordinance Code (Ordinance Code) adopts the 2019 CBC, with amendments, as the County’s Building Code. As such, all new construction within the County is required to adhere to its seismic safety standards. The County of Contra Costa Department of Conservation and Development is responsible for the administration and enforcement of the CBC. Grading, Soils, and Erosion Control Ordinances Ordinance Code Division 716 contains the County’s grading ordinance, which sets forth regulations for control of excavation, grading, earthwork construction, including fills or embankments and related work. Section 716-4.202 requires a grading permit for work on property on which a subdivision or development requiring approval of a tentative map is proposed, such as the proposed Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Geology and Soils FirstCarbon Solutions 3.6-11 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-06 Geology.docx project, and that such a permit shall not be issued until reviewed by the Public Works Department for compliance with the requirements of Title 9, Subdivisions. As indicated in Title 9, Section 94- 4.420, Soil Report, a preliminary soil investigation report is required and must be reviewed by a building inspector or designated representative. If the report is deemed complete in that the recommended action and procedures contained in the report are likely to prevent damage, the recommended actions and procedures contained in the report shall become a condition of approval and shall be incorporated in the proposed development. 3.6.4 - Impacts and Mitigation Measures Significance Criteria According to the California Environmental Quality Act (CEQA) Guidelines Appendix G Environmental Checklist, to determine whether impacts to geology and soils are significant environmental effects, the following questions are analyzed and evaluated. Would the proposed project: a) Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving: i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. ii. Strong seismic ground shaking? iii. Seismic-related ground failure, including liquefaction? iv. Landslides? b) Result in substantial soil erosion or the loss of topsoil? c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse? d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property? e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? f) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Approach to Analysis Impacts related to geology and soils were determined by reviewing information contained in the Preliminary Geotechnical Investigation and Paleontological Records Search prepared for the project site, both of which are provided in Appendix E. Contra Costa County–Oak Road Townhouse Condominiums Project Geology and Soils Draft EIR 3.6-12 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-06 Geology.docx As part of the Preliminary Geotechnical Exploration, ENGEO completed three borings with two CPTs and one SCPT. ENGEO also reviewed historic aerial photographs, geologic mapping, and geotechnical background information. Additional evaluations of potential geologic and soil impacts of the project site were based on review of available documentation, including the General Plan and information available from the Association of Bay Area Governments (ABAG) and the USGS. Impacts to paleontological resources were determined by reviewing the Paleontological Records Search prepared for the project site by Dr. Kenneth L. Finger, a Consulting Paleontologist.21 Specific Thresholds of Significance For purposes of this analysis, the following thresholds are used to evaluate the significance of geology and soils impacts resulting from implementation of the proposed project. • Place structures on or within the State designated zone of a known earthquake fault. • Place structures where seismic ground shaking of a Strong level or greater according to the Mercalli Scale could occur. • Place structures on soils prone to any level of liquefaction. • Place structures on slopes greater than 15 percent or soils susceptible to failure as defined by the USGS. • Place structures in areas without impervious surfaces or vegetation, or on slopes greater than 15 percent. • Place structures on a geologic unit or soil that is unstable or that could become unstable. • Place structures on expansive soil that has an expansion index greater than 20 as defined in Table 18-1-B of the UBC (1994). • Place septic tanks or alternative wastewater disposal systems on soils incapable of supporting the use. • Physically damage or destroy paleontological deposits. Impact Evaluation Earthquakes Impact GEO-1: The proposed project could directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving: i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? Refer to Division of Mines and Geology Special Publication 42. 21 Kenneth L. Finger, PhD. 2021. Paleontological Records Search: Oak Road Project (2648.0017), Unincorporated Contra Costa County. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Geology and Soils FirstCarbon Solutions 3.6-13 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-06 Geology.docx ii) Strong seismic ground shaking. iii) Seismic-related ground failure, including liquefaction. iv) Landslides. Construction Impacts related to risks associated with seismic-related hazards are limited to operational impacts. No construction impacts would occur. Operation i) Ground Rupture Based on the Geologic Peer Review (Appendix E), the potential for ground rupture is low. There are no known active faults directly crossing the project site and the project site is not located within a designated Alquist-Priolo Earthquake Fault Zone. The closest fault to the project site is the Concord fault, approximately 3 miles from the project site.22 As such, it is unlikely for ground rupture to occur at the site. Thus, the proposed project, including the off-site improvements, would not expose people or structures to substantial adverse effects associated with fault rupture. Therefore, no impacts related to fault rupture would occur. ii) Strong Seismic Ground Shaking Potential impacts associated with strong seismic shaking at the project site, including the areas proposed for off-site improvements, include the potential to damage structures or improvements or result in the injury or loss of human life, which could represent a potentially significant impact.23 The risk of damage from ground shaking is controlled by using sound engineering judgment and compliance with the latest provisions of the CBC, as a minimum. The seismic design provisions of the CBC prescribe minimum lateral forces applied statistically to the structure(s), combined with the gravity forces and dead-and-live loads. The code-prescribed lateral forces are generally considered to be substantially smaller than the comparable forces that would be associated with a major earthquake. The intent of the code is to enable structures to (i) resist minor earthquakes without damage, (ii) resist moderate earthquakes without structural damage but with some non-structural damage, and (iii) resist major earthquakes without collapse but with some structural as well as non- structural damage.24 Mitigation Measure (MM) GEO-1a would ensure that the proposed project would incorporate all applicable seismic safety building standards contained in the CBC including seismic design provisions, which would reduce the risk of loss, injury, or death. MM GEO-1b would require geotechnical observation and testing services be conducted during construction as needed, and MM GEO-1c would require the Project Engineer to prepare a final report that documents the field observations and testing services provided during construction as well as provide a professional opinion on the compliance of construction with the recommendations in the Preliminary Geotechnical Investigation. MM GEO-1a, MM GEO-1b, and MM GEO-1c are also applicable to the off-site improvements that 22 Darwin Myers Associates. 2021.

Contra Costa County–Oak Road Townhouse Condominiums Project Geology and Soils Draft EIR 3.6-14 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-06 Geology.docx involve frontage sidewalks, driveway curbs, and gutter improvements including retaining existing on- street parking, and street tree planting. Furthermore, the proposed project would be required to comply with Chapter 74-2 of the Ordinance Code, which requires all construction to conform to the 2019 CBC. As such, with implementation of MM GEO-1a and MM GEO-1b, the proposed project, including the off-site improvements, would not expose people or structures to substantial adverse effects associated with seismic ground shaking. Therefore, impacts would be less than significant with mitigation. iii) Seismic-related Ground Failure As detailed in the Preliminary Geotechnical Exploration, the potential for liquefaction at the project site is moderate to low. The areas proposed for off-site improvements are likely to contain similar soil conditions and susceptibility to liquefaction. ENGEO stated that the amount of total liquefaction- induced settlement corresponds to less than 2.5 inches of differential settlement over a horizontal distance of 40 feet. They concluded that an investigation would be needed to determine whether liquefiable sands are present and to provide stabilization measures where liquefiable sands are confirmed. MM GEO-1a would require the Project Engineer to prepare a design-level Geotechnical Investigation and to incorporate all recommendation from that report into grading and construction drawings to address the presence of liquefiable sands. With implementation of MM GEO-1a, MM GEO-1b, and MM GEO-1c impacts related to seismic-related ground failure, such as liquefaction, ground settlement, and lateral spreading would be less than significant. iv) Landslides Susceptibility to landslide risk is increased where a property contains steep slopes, exposed hillsides or near-vertical cuts often found near creek banks. The project site is relatively flat with no slopes or varied topography that could be susceptible to slope failure, landslides, or soil creep. Due to the relatively flat nature of the project site, the potential for landslides is low to negligible.25 As a result, implementation of the proposed project would not expose people or structures to a landslide hazard, and impacts related to landslides would be less than significant. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures MM GEO-1a Conduct Design-level Geotechnical Exploration At least 60 days prior to recording the final Subdivision Map, or requesting issuance of construction permits or installation of utility improvements, the applicant shall submit a design-level Geotechnical Exploration Report for the proposed project, based on adequate subsurface exploration, laboratory testing and engineering analysis. The scope of the Geotechnical Exploration Report shall address the following potential hazards: (i) grading, including removal of existing undocumented fill that is deemed to be unsuitable for use in engineered fills, preparation to receive fill, compaction standards for fill, etc., (ii) consolidation settlement, (iii) analysis of 25 ENGEO. 2020.

MM GEO-1b Conduct Geotechnical Observation and Testing Services During Construction The design-level geotechnical report required by Mitigation Measure GEO-1a routinely includes recommended geotechnical observation and testing services during construction. These services are essential to the success of the proposed project. They allow the Geotechnical Engineer to (i) ensure geotechnical recommendations for the proposed project are properly interpreted and implemented by contractors, (ii) allow the Geotechnical Engineer to view exposed conditions during construction to ensure that field conditions match those that were the basis of the design recommendations in the approved report, and (iii) provide the opportunity for field modifications of geotechnical recommendations (with Department of Conservation and Development, Community Development Division approval), based on exposed conditions. The monitoring shall commence during clearing, and extend through grading, placement of engineered fill, installation of recommended drainage facilities, and foundation-related work. A hold shall be placed on the "final" grading inspection, pending submittal of a report from the project Geotechnical Engineer that documents their observation and testing services to that stage of construction, including monitoring and testing of backfilling required for utility and drainage facilities. Similarly, a hold shall be placed on the final inspection for each residential building, pending submittal of a letter-report from the Geotechnical Engineer documenting the monitoring services associated with implementation of final grading, drainage, and foundation-related work. This can be one letter that addresses all residential buildings, or separate letters for each building. The geotechnical monitoring shall include documentation of conformance of retaining wall, pier hole drilling/ foundation preparation work and installation of drainage improvements.

The final report can be segmented into an as-graded report that is issued at the end of rough grading, but prior to the installation of the foundations, and a second letter commenting on the inspections made during installation of foundations/parking lot/drainage facilities. The Department of Conservation and Development, Community Development Division (CDD) will place a hold on the final inspection, to ensure that the Geotechnical Engineer’s grading-foundation inspection letter-report is provided prior to requesting the final building inspection for each building. This requirement may be satisfied by issuance of one letter for all residential buildings, or separate letters for each residential building. Level of Significance After Mitigation Less than significant impact. Soil Erosion or Topsoil Loss Impact GEO-2: The proposed project could result in substantial soil erosion or the loss of topsoil. Construction Currently, the site is completely developed with structures, pavement, and landscaping. Since the proposed project would disturb at least 1 acre of land during construction, it would be required to obtain a Construction General Permit from the California State Water Resources Control Board (State Water Board) consistent with the Contra Costa County’s General Permit (No. CAS612008) and to comply with its conditions and requirements, which are designed to minimize potential erosion issues. Consistent with Section 1014-4.002 and .004, compliance with the County’s NPDES permit would ensure that a stormwater control plan is prepared and BMPs are implemented that would prevent sediments and other pollutants from entering the stormwater system. To further reinforce protections related to erosion, MM GEO-2 would require grading, excavation, and filling to occur during the dry season. Thus, with adherence to existing regulatory requirements, as well as limiting grading, excavation, and filling to the dry season, impacts from project construction on the project site, including the off-site improvements, would not result in substantial soil erosion or loss of topsoil. Therefore, construction-related impacts related to soil erosion and loss of topsoil would be less than significant. Operation Impacts related to soil erosion or loss of topsoil are limited to construction impacts. No operational impacts would occur. Level of Significance Before Mitigation Potentially significant impact. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Geology and Soils FirstCarbon Solutions 3.6-17 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-06 Geology.docx Mitigation Measures MM GEO-2 Conduct Grading, Excavation, and Filling Only During the Dry Season All grading, excavation and filling shall be conducted during the dry season (April 15 through October 15) only, and all areas of exposed soils shall be revegetated to minimize erosion and subsequent sedimentation. After October 15, only erosion control work shall be allowed by the grading permit. Any modification to the above schedule shall be subject to review by the Grading Inspection Division, and the review/approval of the Department of Conservation and Development, Community Development Division (CDD). Level of Significance After Mitigation Less than significant impact with mitigation. Unstable Geologic Location Impact GEO-3: The proposed project could be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the proposed project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse. Construction Impacts related to risks associated with location on an unstable geologic unit or soil are limited to operational impacts. No respective construction impacts would occur. Operation As discussed previously in Impact GEO-1(iii), the potential for liquefaction at the project site will be investigated further as part of the design-level Geotechnical Investigation, with recommendations incorporated into grading and construction drawings, as required to address the potential presence of liquefiable sands. In addition, the Preliminary Geotechnical Investigation concluded that the potential for lateral spreading to occur as a result of the occurrence of liquefaction below the project site is low. The project site, including the areas proposed for off-site improvements, do not contain steep slopes, exposed hillsides, or vertical cuts. Due to the gently sloping nature of the project site, including the areas proposed for off-site improvements, the potential for landslides is low. According to the Soil Survey of Contra Costa County (1976), the soil series that occurs on the project site is indicated to be very highly corrosive. Corrosive soil can damage buried metal and result in sulfate attack on foundation concrete. This is a potentially significant impact. In order to reduce or avoid potential impacts related to unstable soils, corrosive soils, or other ground failure, MM GEO-1a would be required to ensure that the proposed project incorporates all applicable seismic safety building standards contained in the CBC as well as all recommendations from a design-level geotechnical exploration. MM GEO-1b would require geotechnical observation and testing services be conducted during construction as needed, and MM GEO-1c would require the Project Engineer to prepare a final report that documents the field observations and testing services provided during construction as well as provide a professional opinion on the compliance of Contra Costa County–Oak Road Townhouse Condominiums Project Geology and Soils Draft EIR 3.6-18 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-06 Geology.docx construction with the recommendations in the design-level geotechnical exploration. MM GEO-1a, MM GEO-1b, and MM GEO-1c are also applicable to the off-site improvements. Therefore, impacts related to unstable soils, corrosive soils, or other ground failure would be less than significant with mitigation. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures Implement MM GEO-1a, MM GEO-1b, and MM GEO-1c. Level of Significance After Mitigation Less than significant impact with mitigation. Expansive Soil Impact GEO-4: The proposed project could be located on expansive soil, as defined in Table 18-1- B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property. Construction Impacts related to risks associated with location on expansive soil are limited to operational impacts. No respective construction impacts would occur. Operation The CPT data, collected during the Preliminary Geotechnical Investigation, suggests clayey soil is present at the site, which may exhibit expansive potential. The presence of potentially expansive soil shall be further evaluated during the design-level geotechnical exploration. Darwin Meyer Associates state that the soil present on-site, Clear Lake clay, is highly expansive. Expansive soils expand when water is added and shrink when they dry out. This continuous change in soils volume could cause homes and other structures to move unevenly and crack. With implementation of MM GEO-1a, MM GEO-1b, and MM GEO-1c, the proposed project, including the off-site improvements, would not create a substantial risk to life or property from being located on expansive soils. Therefore, impacts related to expansive soils would be less than significant with mitigation. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures Implement MM GEO-1a, MM GEO-1b, and MM GEO-1c. Level of Significance After Mitigation Less than significant impact with mitigation.

Construction Impacts related to soil capability of supporting the use of alternative wastewater disposal systems are limited to operational impacts. No construction impacts would occur. Operation The proposed project is located within an urbanized portion of the County. The proposed project would include wastewater infrastructure and connections to the existing sanitary sewer lines contained with Oak Road. Wastewater treatment capacity impacts are discussed further under Section 3.15, Utilities and Service Systems. Thus, there would be no operational impact related to soil capability of supporting the use of alternative wastewater disposal systems. Level of Significance No impact. Destruction of Paleontological Resource or Unique Geologic Feature Impact GEO-6: The proposed project would not directly or indirectly destroy a unique paleontological resource or site or unique geologic feature. Construction No known paleontological resources are located within the project site boundaries. As detailed in the Paleontological Records Search (Appendix E), the surface area of the project sites consists of solely Holocene alluvium, which is too young to contain significant vertebrate fossils. The 0.5-mile search area around the project site boundary also only contains Holocene alluvium. The nearest area with potential to contain significant fossils are resources is in the outcrop belt of Miocene Monterey Formation shale and sandstone, and the Paleocene Martinez Formation. These bedrock exposures occur outside of the search area. The absence of Pleistocene or older deposits in the search area suggests that any potential paleontological resources underlying the project site would be at depths below all the earth-disturbing construction activities at the project site. In addition, there are no unique geological features located on the project site. Therefore, impacts related to destruction of paleontological resources or unique geologic features would be less than significant. Nonetheless, development activities have the potential to encounter undiscovered paleontological resources. Accordingly, MM GEO-6 requires the implementation of standard inadvertent discovery measures in the event paleontological resources are encountered during construction. The implementation of this mitigation measure will ensure that construction shall stop in the vicinity of any potential resource until the significance of the resource is confirmed, and will ensure that significant resources will be avoided or excavated and preserved. With incorporation of MM GEO-6, impacts associated with paleontological resources would be less than significant.

Mitigation Measures MM GEO-6 Stop Construction Upon Encountering Paleontological Materials In the event that fossils or fossil-bearing deposits are discovered during construction activities, excavations within a 50-foot radius of the find shall be temporarily halted or diverted. The project contractor shall notify a qualified Paleontologist to examine the discovery. The Paleontologist shall document the discovery as needed (in accordance with Society of Vertebrate Paleontology [SVP] standards), evaluate the potential resource, and assess the significance of the find under the criteria set forth in CEQA Guidelines Section 15064.5. The Paleontologist shall notify the appropriate agencies to determine procedures that would be followed before construction activities are allowed to resume at the location of the find. If the applicant determines that avoidance is not feasible, the Paleontologist shall prepare an excavation plan for mitigating the effect of construction activities on the discovery. The excavation plan shall be submitted to the Lead Agency for review and approval prior to implementation, and the applicant shall adhere to the recommendations in the excavation plan. 3.6.5 - Cumulative Impacts The geographic scope of the cumulative analysis related to geology and soils is the project site and its vicinity. Adverse effects associated with geology and soils tend to be localized; therefore, an area generally within a 0.25-mile radius would be the area most affected by activities associated with the proposed project. The analysis considers the foreseeable development projects listed in Table 3-1 (See Chapter 3, Environmental Impact Analysis) in unincorporated Contra Costa County and the surrounding cities, in addition to the proposed project.

Cumulative projects, including the proposed project, have the potential to experience moderate to strong ground shaking from earthquakes. Projects listed in Table 3-1 would be exposed to the same ground shaking hazards and would be subject to the same requirements as the proposed project. Cumulative projects would adhere to the provisions of the CBC, policies of the General Plan, and the Ordinance Code to reduce potential hazards associated with seismic ground shaking and ground failure. As such, the proposed project, in conjunction with other projects, would not have a cumulatively significant impact associated with seismic-related hazards. Soil-related Hazards Soil conditions associated with the project site, such as expansive soils, corrosive soils, and soil settlement are specific to the project site and generally do not contribute to a cumulative effect. Some or all other cumulative projects may have similar conditions, but they would not contribute to cumulative soil-related hazards. The proposed project would be subject to General Plan policies and the Ordinance Code to reduce soil-related hazards. Other current and future development/redevelopment projects in the region would similarly be required to adhere to standards and practices that include stringent geologic and soil-related hazard mitigations. As such, the proposed project, in conjunction with other projects, would not have a cumulatively significant impact associated with soil-related hazards. Paleontological Resources and Unique Geologic Feature None of the projects listed in Table 3-1 would occur within 0.25 mile of the project site. Construction activities associated with development of cumulative projects in the project vicinity may have the potential to encounter undiscovered geologic resources or paleontological resources. These cumulative projects would be required to mitigate for impacts through compliance with applicable federal and State laws governing geologic resources and paleontological resources. The likelihood that geologic resources or paleontological resources are present on the cumulative project sites is relatively low, given that the majority of soil disturbance associated with these projects will take place within Holocene soils too young to be fossiliferous. Although there is the possibility that previously undiscovered resources could be encountered by subsurface earthwork activities, the implementation of standard construction practices and MM GEO-6 would ensure that undiscovered geologic resources and paleontological resources are not adversely affected by cumulative project- related construction activities. Given the low potential for disruption and the comprehensiveness of mitigation measures that would apply to the cumulative projects, the project, in conjunction with other planned and approved projects, would result in a less than significant cumulative impact related to paleontological and geologic resources. Level of Cumulative Significance Less than significant impact.

Description and analysis are based on information provided by the Oak Road Townhouse Condominiums Air Quality and Greenhouse Gas Assessment prepared by Illingworth & Rodkin, Inc on May 17, 2021.1 No comments were received during the Draft Environmental Impact Report (Draft EIR) scoping period related to GHG emissions. 3.7.2 - Environmental Setting Greenhouse Effect, Global Warming, and Climate Change Most of the energy that affects the Earth’s climate comes from the sun. Some solar radiation is absorbed by the Earth’s surface, and a smaller portion of this radiation is reflected by the atmosphere back toward space. As the Earth absorbs high-frequency solar radiation, its surface gains heat and then re-radiates lower frequency infrared radiation back into the atmosphere.2 Most solar radiation passes through gases in the atmosphere classified as GHGs; however, infrared radiation is selectively absorbed by GHGs. GHGs in the atmosphere play a critical role in maintaining the balance between the Earth’s absorbed and radiated energy, the Earth’s radiation budget,3 by trapping some of the infrared radiation emitted from the Earth’s surface that otherwise would have escaped to space (Figure 3.7-1). Radiative forcing is the difference between the incoming energy and outgoing energy.4 Specifically, GHGs affect the radiative forcing of the atmosphere,5 which in turn affects the Earth’s average surface temperature. This phenomenon, the greenhouse effect, keeps the Earth’s atmosphere near the surface warmer than it would be otherwise and allows successful habitation by humans and other forms of life. Combustion of fossil fuels and deforestation release carbon into the atmosphere that was previously stored underground in sediments or in surface vegetation, thus exchanging carbon from the geosphere and biosphere to the atmosphere in the carbon cycle. With the accelerated increase in fossil fuel combustion and deforestation since the Industrial Revolution of the 19th Century, concentrations of GHGs in the atmosphere have increased exponentially. Such emissions of GHGs in excess of natural ambient concentrations contribute to the enhancement of the natural greenhouse effect . This enhanced greenhouse effect has contributed to global warming, an increased rate of warming of the Earth’s average surface temperature.6 Specifically, increases in GHGs lead to increased absorption of infrared radiation by the Earth’s atmosphere and warm the lower atmosphere further, thereby increasing temperatures and evaporation rates near the surface. 1 Illingworth & Rodkin, Inc. 2021. Oak Road Townhouse Condominiums Air Quality & Greenhouse Gas Assessment. May 17. 2 Frequencies at which bodies emit radiation are proportional to temperature. The Earth has a much lower temperature than the sun and emits radiation at a lower frequency (longer wavelength) than the high-frequency (short-wavelength) solar radiation emitted by the sun. 3 This includes all gains of incoming energy and all losses of outgoing energy; the planet is always striving to be in equilibrium. 4 Positive forcing tends to warm the surface while negative forcing tends to cool it. 5 This is the change in net irradiance at the tropopause after allowing stratospheric temperatures to readjust to radiative equilibrium, but with surface and tropospheric temperatures and state held fixed at the unperturbed values. 6 This condition results when the Earth has to work harder to maintain its radiation budget, because when more GHGs are present in the atmosphere, the Earth must force emissions of additional infrared radiation out into the atmosphere.

Climate change is a change in the average weather of the Earth measured by alterations in wind patterns, storms, precipitation, and temperature. These changes are assessed using historical records of temperature changes occurring in the past, such as during previous ice ages. Many of the concerns regarding climate change use this data to extrapolate a level of statistical significance specifically focusing on temperature records from the last 150 years (the Industrial Age) that differ from previous climate changes in rate and magnitude. 7 These basic conclusions have been endorsed by more than 45 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. Since 2007, no scientific body of national or international standing has maintained a dissenting opinion.

The IPCC constructed several emission trajectories of GHGs needed to stabilize global temperatures and climate change impacts. In its Fourth Assessment Report, the IPCC predicted that the global mean temperature change from 1990 to 2100, given six scenarios, could range from 1.1°C (degrees Celsius) to 6.4°C. Regardless of analytical methodology, global average temperatures and sea levels are expected to rise under all scenarios.8 The report also concluded that “[w]arming of the climate system is unequivocal,” and that “[m]ost of the observed increase in global average temperatures since the mid-20th Century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations.” Global surface temperature increased approximately 1.33°F (degrees Fahrenheit) over the last 100 years. The IPCC predicts increases in global average temperature of between 2°F and 11°F over the next 100 years, depending on the scenario.9 Greenhouse Gases and Global Emission Sources Gases that trap heat in the atmosphere are referred to as GHGs. The effect is analogous to the way a greenhouse retains heat. Prominent GHGs that naturally occur in the Earth’s atmosphere are water vapor, carbon dioxide (CO2), methane (CH4), oxides of nitrogen (NOX), and ozone. Anthropogenic (human-caused) GHG emissions include releases of these GHGs plus release of human-made gases with high global warming potential (GWP) (ozone-depleting substances such as chlorofluorocarbons [CFCs])10 and aerosols, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). The GHGs listed by the IPCC (CO2, methane, nitrous oxide, HFCs, PFCs, and sulfur hexafluoride) are discussed below, in order of abundance in the atmosphere. Water vapor, despite being the most abundant GHG, is not discussed because natural concentrations and fluctuations far outweigh anthropogenic influences, making it impossible to predict. Ozone is not included because it does not directly affect radiative forcing. Ozone-depleting substances, which include chlorofluorocarbons, halons, carbon tetrachloride, methyl chloroform, and hydrochlorofluorocarbons, are not included because HFCs and PFCs have largely replaced them. The GWP is the potential of a gas or aerosol to trap heat in the atmosphere. The GWP of a gas is essentially a measurement of the radiative forcing of a GHG compared with the reference gas, carbon dioxide (CO2). Individual GHG compounds have varying potential for contributing to global warming. For example, methane is 25 times as potent as CO2, while sulfur hexafluoride is 22,200 times more potent than CO2 on a molecule-per-molecule basis. To simplify reporting and analysis, methods have been set forth to describe emissions of GHGs in terms of a single gas.

The GWP of a GHG is a measure of how much a given mass of a GHG is estimated to contribute to global warming. Thus, to describe how much global warming a given type and amount of GHG may cause, the CO2e is used. A CO2e is the mass emissions of an individual GHG multiplied by its GWP. As such, a high GWP represents high absorption of infrared radiation and a long atmospheric lifetime compared to CO2. One must also select a time horizon to convert GHG emissions to equivalent CO2 emissions to account for chemical reactivity and lifetime differences among various GHG species. The standard time horizon for climate change analysis is 100 years. Generally, GHG emissions are quantified in terms of metric tons (MT) of CO2e emitted per year. The atmospheric residence time of a gas is equal to the total atmospheric abundance of the gas divided by its rate of removal.12 The atmospheric residence time of a gas is, in effect, a half-life measurement of the length of time a gas is expected to persist in the atmosphere when accounting for removal mechanisms such as chemical transformation and deposition. Table 3.7-1 lists the GWP of each GHG and its lifetime. Units commonly used to describe the concentration of GHGs in the atmosphere are parts per million (ppm), parts per billion (ppb), and parts per trillion (ppt), referring to the number of molecules of the GHG in a sampling of 1 million, 1 billion, or 1 trillion molecules of air. Collectively, HFCs, PFCs, and sulfur hexafluoride are referred to as high GWP gases. CO2 is by far the largest component of worldwide CO2e emissions, followed by methane, nitrous oxide, and high GWP gases, in order of decreasing contribution to CO2e. The primary human processes that release GHGs include the burning of fossil fuels for transportation, heating, and electricity generation; agricultural practices that release methane, such as livestock grazing and crop residue decomposition; and industrial processes that release smaller amounts of high GWP gases. Deforestation and land cover conversion are also identified as contributing to global warming by reducing the Earth’s capacity to remove CO2 from the air and altering the Earth’s albedo or surface reflectance, thus allowing more solar radiation to be absorbed. Specifically, CO2 emissions associated with fossil fuel combustion are the primary contributors to human-induced climate change. CO2, methane, and nitrous oxide emissions associated with human activities are the next largest contributors to climate change. GHGs of California concern are defined by Assembly Bill (AB) 32 (see the Regulatory Environment subsection below for a description) and include CO2, CH4, NOX, HFCs, PFCs, and SF6. A seventh GHG, nitrogen trifluoride (NF3), was also added under the California Health and Safety Code Section 38505(g)(7) as a GHG of concern. These GHGs are described in terms of their physical description and properties, GWP, atmospheric residence lifetime, sources, and atmospheric concentration in 2005 in Table 3.7-1. 11 Intergovernmental Panel on Climate Change, United Nations. 2007.

The State has begun the process of addressing pollutants referred to as short-lived climate pollutants. Senate Bill (SB) 605, approved by the Governor on September 14, 2014, required the California Air Resources Board (ARB) to complete a comprehensive strategy to reduce emissions of short-lived climate pollutants by January 1, 2016. The ARB released the Proposed Short-Lived Climate Pollutant Reduction Strategy in April 2016. The ARB has completed an emission inventory of these pollutants, identified research needs, identified existing and potential new control measures that offer co -benefits, and coordinated with other State agencies and districts to develop measures. The short-lived climate pollutants include three main components: black carbon, fluorinated gases, and methane. Fluorinated gases and methane are described in Table 3.7-1 and are already included in the California GHG inventory. Black carbon has not been included in past GHG inventories; however, the ARB will include it in its comprehensive strategy.13 Black carbon is a component of fine particulate matter. Incomplete combustion of fossil fuels, biofuels, and biomass creates black carbon. Sources within a jurisdiction may include exhaust from diesel trucks, vehicles, and equipment, as well as smoke from biogenic combustion. Biogenic combustion sources of black carbon include the burning of biofuels used for transportation, the burning of biomass for electricity generation and heating, prescribed burning of agricultural residue, and natural and unnatural wildfires. Black carbon is not a gas but an aerosol—particles or liquid droplets suspended in air. Black carbon only remains in the atmosphere for days to weeks, whereas other GHGs can remain in the atmosphere for years. Black carbon can deposit on snow, where it absorbs sunlight, reduces sunlight reflectivity, and hastens snowmelt. Direct effects include absorbing incoming and outgoing radiation; indirectly, black carbon can also affect cloud reflectivity, precipitation, and surface dimming (cooling). 13 California Air Resources Board (ARB). 2017.

The ARB has identified a GWP of 3,200 using a 20-year time horizon and 900 using a 100-year time horizon from the IPCC Fifth Assessment. The ARB already regulates black carbon sources, air district criteria pollutants, and toxics to control fine particulate emissions from diesel engines and other combustion sources.14 Additional controls on the sources of black carbon specifically for their GHG impacts beyond those required for toxic and fine particulates are not likely necessary. Ozone is another short-lived climate pollutant that will be part of the strategy. Ozone affects evaporation rates, cloud formation, and precipitation levels. Ozone is not a direct emission, so its precursor emissions, volatile organic compounds (VOC) and nitrogen oxides (NOX) on a regional scale, and CH4 on a hemispheric scale, will be subject of the strategy.15 Water vapor is also considered a GHG. Water vapor is an important component of our climate system and is not regulated. Increasing water vapor leads to warmer temperatures, which causes more water vapor to be absorbed into the air. Warming and water absorption increase in a spiraling cycle. Water vapor feedback can also amplify the warming effect of other GHGs, such that the warming brought about by increased GHGs allows more water vapor to enter the atmosphere.16 Introduction to Global Climate Change Global climate change is defined as the change in average meteorological conditions on Earth with respect to temperature, precipitation, and storms. Global temperatures are regulated by naturally occurring atmospheric gases such as water vapor, CO2, N2O, CH4, hydrofluorocarbons, perfluorocarbons and SF6. These particular gases are important because of their residence time (duration they stay) in the atmosphere, which ranges from 10 years to more than 100 years. These gases allow solar radiation into the Earth’s atmosphere, but prevent radioactive heat from escaping, thus warming the Earth’s atmosphere. Global climate change can occur naturally, as it has in the past with the previous ice ages. According to the ARB, the climate change since the Industrial Revolution differs from previous climate changes in both rate and magnitude. GHGs are released into the atmosphere by both natural and anthropogenic (human) activity. Without the natural greenhouse effect, the Earth’s average temperature would be approximately 61°F cooler than it is currently. The cumulative accumulation of these gases in the Earth’s atmosphere is considered the cause for the observed increase in the Earth’s temperature. Although California’s rate of growth of GHG emissions is slowing, the State is still a substantial contributor to the U.S. emissions inventory total. In 2004, California is estimated to have produced 492 million metric tons (MMT) of carbon dioxide equivalents (MMT CO2e) GHG emissions. Despite a population increase of 16 percent between 1990 and 2004, California has significantly slowed the rate of growth of GHG emissions because of the implementation of energy efficiency programs as well as adoption of strict emission controls. 14 California Air Resources Board (ARB). 2017.

Pollutants with localized air quality effects have relatively short atmospheric lifetimes, approximately 1 day; by contrast, GHGs have long atmospheric lifetimes, several years to several thousand years. GHGs persist in the atmosphere for a long enough time to disperse around the globe. Although the exact lifetime of any particular GHG molecule depends on multiple variables and cannot be pinpointed, more CO2 is currently emitted into the atmosphere than is sequestered. CO2 sinks, or reservoirs, include vegetation and the ocean, which absorb CO2 through photosynthesis and dissolution, respectively. These are two of the most common processes of CO2 sequestration. Of the total annual human-caused CO2 emissions, approximately 54 percent is sequestered through ocean uptake, Northern Hemisphere forest regrowth, and other terrestrial sinks within a year, whereas the remaining 46 percent of human-caused CO2 emissions is stored in the atmosphere.17 Similarly, effects of GHGs are borne globally, as opposed to the localized air quality effects of criteria air pollutants and hazardous air pollutants. The quantity of GHGs required to result in climate change is not precisely known and cannot be quantified, and no single project would be expected to measurably contribute to a noticeable incremental change in the global average temperature, or to global or local climates or microclimate. Emissions of GHGs have the potential to adversely affect the environment because such emissions contribute, on a cumulative basis, to global climate change. A cumulative discussion and analysis of project impacts on global climate change is presented in this Draft EIR because, although it is unlikely that a single project will contribute significantly to climate change, cumulative emissions from many projects affect global GHG concentrations and the climate system. Global climate change has the potential to result in sea level rise (resulting in flooding of low-lying areas), to affect rainfall and snowfall (leading to changes in water supply), to affect temperatures and habitats (affecting biological resources and public health), and to result in many other adverse environmental consequences. Although the international, national, state, and regional communities are beginning to address GHGs and the potential effects of climate change, worldwide GHG emissions will likely continue to rise over the next decades. Climate and Topography Climate is the accumulation of daily and seasonal weather events over a long period, whereas weather is defined as the condition of the atmosphere at any particular time and place.

Total U.S. GHG emissions increased by 1.8 percent from 1990 to 2019 (from 6,233.2 MMT CO2e in 1990 to 6,658.3 MMT CO2e in 2019). Since 1990, U.S. emissions have increased at an average annual rate of 0.1 percent. Between 2018 and 2019, the decrease in total greenhouse gas emissions was largely driven by the decrease in CO2 emissions from fossil fuel combustion. The decrease in CO2 emissions from fossil fuel combustion was a result of a 1 percent decrease in total energy use and reflects a continued shift from coal to less carbon intensive natural gas and renewables in the electric power sector. Note: Emissions shown do not include carbon sinks such as change in land uses and forestry, which removes approximately 12 percent of these GHG emissions.

During the 2000 to 2017 period, per capita GHG emissions in California have continued to drop from a peak in 2001 of 14 MT CO2e per capita to 10.7 MT CO2e per capita in 2017, a 24 percent decrease. Overall trends in the inventory also demonstrate that the carbon intensity of California’s economy (the amount of carbon pollution per million dollars of gross domestic product [GDP]) is declining, representing a 41 percent decline since the 2001 peak, while the State’s GDP has grown 52 percent during this period. For the first time since California started to track GHG emissions, the majority of California’s electricity comes from zero-GHG sources (hydropower, solar, wind, and nuclear energy).21 19 California Climate Change Center (CCCC). 2006.

Table 3.7-2 shows the 2011 breakdown of emissions by end-use sector for each county within BAAQMD’s jurisdiction. The estimated GHG emissions are presented in CO2e, which weights each GHG by its GWP. The GWPs used in the BAAQMD inventory are from the Second Assessment Report of the IPCC. In 2011, GHG emissions from Contra Costa County (County) accounted for approximately 36 percent of the Bay Area’s total GHG emissions with approximately 57 percent of the Bay Area’s total GHG emissions coming from the industrial/commercial land uses in the County.23 Transportation is the largest GHG emissions sector in the Bay Area, followed by industrial/commercial, electricity generation and cogeneration, and residential fuel usage. In the County, the industrial/commercial sector generate the largest amount of GHG emissions, followed by the electricity/cogeneration sector.

However, no active school currently exists on the project site and there are no existing residences or other uses within the project site that would generate GHG emissions. Climate Change Trends and Effects CO2 accounts for more than 75 percent of all anthropogenic GHG emissions, the atmospheric residence time of CO2 is decades to centuries, and global atmospheric concentrations of CO2 continue to increase at a faster rate than ever previously recorded. Thus, the warming impacts of CO2 will persist for hundreds of years after mitigation implementation to reduce GHG concentrations. 24 Contra Costa County Department of Conservation and Development and Michael Baker International. 2015.

Statewide average temperatures increased by about 1.7°F from 1895 to 2011, and a larger proportion of total precipitation is falling as rain instead of snow.27 Sea level rose by as much as 7 inches along the California coast over the last century, leading to increased erosion and adding pressure to the State’s infrastructure, water supplies, and natural resources. These observed trends in California’s climate are projected to continue in the future. Research indicates that California will experience overall hotter and drier conditions with a continued reduction in winter snow (with concurrent increases in winter rains), as well as increased average temperatures and accelerating sea level rise. The frequency, intensity, and duration of extreme weather events such as heat waves, wildfires, droughts, and floods will also change.28 In addition, increased air pollution and spread of insects potentially carrying infectious diseases will also occur as the climate-associated temperature and associated species clines shift in latitude. The following is a summary of climate change factors and predicted trends specific to California. In California, climate change may result in consequences such as the following:29,30 • A reduction in the quality and supply of water from the Sierra snowpack. If heat-trapping emissions continue unabated, more precipitation will fall as rain instead of snow, and the snow that does fall will melt earlier, reducing the Sierra Nevada spring snowpack by as much as 70 to 90 percent. This can lead to challenges in securing adequate water supplies. It can also lead to a potential reduction in hydropower. • Increased risk of large wildfires. If rain increases as temperatures rise, wildfires in the grasslands and chaparral ecosystems of Southern California are estimated to increase by approximately 30 percent toward the end of the 21st Century because more winter rain will stimulate the growth of more plant “fuel” available to burn in the fall. In contrast, a hotter, drier climate could promote up to 90 percent more Northern California fires by the end of the century by drying out and increasing the flammability of forest vegetation. • Reductions in the quality and quantity of certain agricultural products. The crops and products likely to experience adverse effects include wine grapes, fruit, nuts, and milk. 25 California Natural Resources Agency (CNRA). 2009. 2009 California Climate Adaptation Strategy: A Report to the Governor of the State of California in Response to Executive Order S-13-2008. 26 California Climate Change Center (CCCC). 2012.

If temperatures rise to the medium warming range, there could be 75 to 85 percent more days with weather conducive to ozone formation in Los Angeles and the San Joaquin Valley, relative to today’s conditions. This is more than twice the increase expected if rising temperatures remain in the lower warming range. This increase in air quality problems could result in an increase in asthma and other health-related problems. • A rise in sea levels resulting in the displacement of coastal businesses and residences. During the past century, sea levels along California’s coast have risen about 7 inches. If emissions continue unabated and temperatures rise into the higher anticipated warming range, sea level is expected to rise an additional 22 to 35 inches by the end of the century. Elevations of this magnitude would inundate coastal areas with salt water, accelerate coastal erosion, threaten vital levees and inland water systems, and disrupt wetlands and natural habitats. • An increase temperature and extreme weather events. Climate change is expected to lead to increases in the frequency, intensity, and duration of extreme heat events and heat waves in California. More heat waves can exacerbate chronic disease or heat-related illness. • A decrease in the health and productivity of California’s forests. Climate change can cause an increase in wildfires, an enhanced insect population, and establishment of non-native species. Bay Area The following is a summary of climate change factors and predicted trends specific to the Bay Area. Temperature, Heat, Drought, and Wildfire Events The Bay Area is expected to experience warming over the rest of the 21st Century. Consistent with Statewide projections, the annual average temperature in the Bay Area will likely increase by 2.7°F between 2000 and 2050, based on GHGs that have already been emitted into the atmosphere. By the end of the century, the increase in the Bay Area’s annual average temperature may range from approximately 3.5°F to 11°F relative to the average annual temperature simulated for the 1961–1990 baseline period used for the study, depending on the GHG emissions scenarios.31 The projected rate of warming, especially in the latter half of the 21st Century, is considerably greater than warming rates derived from historical observed data. Specific predictions related to temperature/heat are summarized below. • The annual average temperature in the Bay Area has been increasing over the last several decades. • The Bay Area is expected to see an increase in average annual temperature of 2.7°F by 2050, and 3.5°F to 11°F by 2100. Projections show a greater warming trend during the summer season. The coastal parts of the Bay Area will experience the most moderate warming trends.32 31 California Climate Change Center (CCCC). 2009.

Extreme freeze events are expected to decrease in frequency and severity by 2100, but occasional colder-than-historical events may occur by 2050.33 Precipitation, Rainfall, and Flooding Events Studies of the effect of climate change on the long-term average precipitation for California show some variance.34 Considerable variability exists across individual models and examining the average changes can mask more extreme scenarios that project much wetter or drier conditions. California is expected to maintain a Mediterranean climate through the next century, with dry summers and wet winters that vary between seasons, years, and decades. Wetter winters and drier springs are also expected, but overall annual precipitation is not projected to change substantially. By midcentury, more precipitation is projected to occur in winter in the form of less frequent but larger events. The majority of global climate models predict drying trends across the State by 2100.35 Specific factors related to precipitation/rainfall/extreme events are summarized below. • The Bay Area has not experienced substantial changes in rainfall depth or intensities over the past 30 years. • The Bay Area will continue to experience a Mediterranean climate, with little change in annual precipitation projected by 2050, although a high degree of variability may persist. • An annual drying trend is projected to occur by 2100. The greatest decline in precipitation is expected to occur during the spring months, while minimal change is expected during the winter months. • Increases in drought duration and frequency coupled with higher temperatures, as experienced in 2012, 2013, and 2014, will increase the likelihood of wildfires. • California is expected to see increases in the magnitude of extreme events, including increased precipitation delivered from atmospheric river events, which would bring high levels of rainfall during short time periods and increase the chance of flash floods. The Bay Area is also expected to see an increase in precipitation intensities, but possibly through less frequent events.36 Reduced Sierra Nevada Snowpack and Water Supply Shortages If heat-trapping emissions continue unabated, more precipitation will fall as rain instead of snow, and the snow that does fall will melt earlier, reducing the Sierra Nevada spring snowpack by as much as 70 to 90 percent. This can lead to challenges in securing adequate surface water supplies. 33 Cal-Adapt. 2021. Climate Tools. Website: http://cal-adapt.org/tools/.

Air Quality and Pollution Events Warming-induced increases in the frequency of smog (ground-level ozone) events and particulate air pollution will exacerbate respiratory disorders.37 Although there could be health effects resulting from changes in the climate and the consequences that can occur, inhalation of GHGs at levels currently in the atmosphere would not result in adverse health effects, with the exception of ozone and aerosols (particulate matter). The potential health effects of ozone and particulate matter are discussed in criteria pollutant analyses. At very high indoor concentrations (not at levels existing outside), carbon dioxide, methane, SF6, and some chlorofluorocarbons can cause suffocation as the gases can displace oxygen.38,39 Contra Costa County Temperature and Heat Figure 3.7-4 displays a chart of measured historical (i.e., observed) and projected annual average temperatures in the County area. As shown in Figure 3.7-4, temperatures are expected to rise as part of both the low and high GHG emissions scenarios.40 The results indicate that temperatures are predicted to increase by 3.9°F under the medium emission scenario and 6.7°F under the high emissions scenario.41 37 United States Environmental Protection Agency (EPA). 2009.

The higher global GHG emissions scenario (A1) assumes a global trend of rapid economic growth. The lower GHG emissions scenario (B1) assumes the same global population as in the A1 storyline but with rapid changes in economic structures toward a service and information economy, with reductions in material intensity, and the introduction of clean and resource-efficient technologies. Overall, the B1 scenario places more focus on global environmental sustainability rather than rapid economic growth. 41 CalAdapt. 2021. Local Climate Snapshots.

Fires easily ignite in grassland ecosystems, particularly in dry seasons. (See Section 3.16, Wildfire, for a more detailed discussion related to wildfire hazard areas and wildfire-conducive conditions.) The potential for increased temperatures and drought conditions due to climate change would result in increased risk from wildfire in these areas. Reduced Sierra Nevada Snowpack and Water Supply Shortages As described in Section 3.15, Utilities and Service Systems, the County receives potable water from the Contra Costa Water District (CCWD), which pumps water from four intakes in the San Joaquin Delta. Central Valley Project (CVP) provides the CCWD’s water supply, which receives water from storage releases from Shasta, Folsom, and Trinity reservoirs into the Sacramento River in the San Joaquin Delta.42 Originating in the Sierra Nevada, water flows into the Sacramento and San Joaquin Rivers into the Delta where it is drawn and transported via Contra Costa Canal. The availability of surface water supply could decline if climate change results in reduced snowpack in the Sierra Nevada. Climate Change Impacts at the Project Site Specific climate change impacts that could affect the project include: 42 United States Department of the Interior Bureau of Reclamation. 2020.

By late this century, all projections show drying, and half of the projections suggest 30-year average precipitation will decline by more than 10 percent below the historical average. • This drying trend is caused by an apparent decline in the frequency of rain and snowfall. Even in projections with relatively small or no declines in precipitation, central and southern parts of the State can be expected to be drier from the warming effects alone—the spring snowpack will melt sooner, and the moisture in soils will evaporate during long dry summer months.43 • Wildfire Risks. Earlier snowmelt, higher temperatures, and longer dry periods over a longer fire season will directly increase wildfire risk. Indirectly, wildfire risk will also be influenced by potential climate related changes in vegetation and ignition potential from lightning. Human activities will continue to be the biggest factor in ignition risk. The number of large fires Statewide is estimated to increase from 58 percent to 128 percent above historical levels by 2085. Under the same emissions scenario, estimated burned area will increase by 57 percent to 169 percent, depending on location.44 • Health Impacts. Many of the gravest threats to public health in California stem from the increase of extreme conditions, principally more frequent, more intense, and longer heat waves. Particular concern centers on the increasing tendency for multiple hot days in succession, and heat waves occurring simultaneously in several regions throughout the State. Public health could also be affected by climate change impacts on air quality, food production, the amount and quality of water supplies, energy pricing and availability, and the spread of infectious diseases. Higher temperatures also increase ground-level ozone levels. Furthermore, wildfires can increase particulate air pollution in the major air basins of California.45 • Increased Energy Demand. Increases in average temperature and higher frequency of extreme heat events combined with new residential development across the State will drive up the demand for cooling in the increasingly hot and long summer season and decrease demand for heating in the cooler season. Warmer, drier summers also increase system losses at natural gas plants (reduced efficiency in the electricity generation process at higher temperatures) and hydropower plants (lower reservoir levels). Transmission of electricity will also be affected by climate change. Transmission lines lose 7 to 8 percent of transmitting capacity in high temperatures while needing to transport greater loads. This means that more electricity needs to be produced to make up for the loss in capacity and the growing demand.46 43 California Climate Change Center (CCCC). 2012, July.

The major feature of the Kyoto Protocol is that it sets binding targets for 37 industrialized countries and the European community for reducing GHG emissions at average of 5 percent against 1990 levels over the 5-year period from 2008–2012. The Convention (as discussed above) encouraged industrialized countries to stabilize emissions; however, the Protocol commits them to do so. Developed countries have contributed more emissions over the last 150 years; therefore, the Protocol places a heavier burden on developed nations under the principle of “common but differentiated responsibilities.” In 2001, President George W. Bush indicated that he would not submit the treaty to the U.S. Senate for ratification, which effectively ended American involvement in the Kyoto Protocol. In December 2009, international leaders met in Copenhagen to address the future of international climate change commitments post-Kyoto . Leaders did not reach a binding agreement in Copenhagen; however, the Committee identified the long-term goal of limiting the maximum global average temperature increase to no more than 2°C above preindustrial levels, subject to a review in 2015. The Climate Change Committee held additional meetings in Durban, South Africa in November 2011; Doha, Qatar in November 2012; and Warsaw, Poland in November 2013. The meetings are gradually gaining consensus among participants on individual climate change issues. On September 23, 2014, more than 100 heads of state and government, and leaders from the private sector and civil society met at the Climate Summit in New York hosted by the United Nations. At the Summit, heads of government, business and civil society announced actions in areas that would have the greatest impact on reducing emissions, including climate finance, energy, transport, industry, agriculture, cities, forests, and building resilience. United Nations Climate Change Framework Convention On March 21, 1994, the United States joined a number of countries around the world in signing the United Nations Climate Change Framework Convention. Under the Convention, governments agreed to gather and share information on GHG emissions, national policies, and best practices; launch national strategies for addressing GHG emissions and adapting to expected impacts, including the provision of financial and technological support to developing countries; and cooperate in preparing for adaptation to the impacts of climate change. Paris Climate Change Agreement Parties to the United Nations Framework Convention on Climate Change (UNFCCC) reached a landmark agreement on December 12 in Paris, charting a fundamentally new course in the two-decade-old global climate effort. Culminating a 4-year negotiating round, the new treaty ends the strict differentiation between developed and developing countries that characterized earlier efforts, replacing it with a common framework that commits all countries to put forward their best efforts and Contra Costa County—Oak Road Townhouse Condominimums Project Greenhouse Gas Emissions Draft EIR 3.7-20 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-07 GHG.docx to strengthen them in the years ahead. This includes, for the first time, requirements that all parties report regularly on their emissions and implementation efforts, and undergo international review. The agreement and a companion decision by parties were the key outcomes of the conference, known as the 21st Session of the UNFCCC Conference of the Parties, or “COP 21.” Together, the Paris Agreement and the accompanying COP 21 decision: 47 • Reaffirm the goal of limiting global temperature increase well below 2 degrees Celsius, while urging efforts to limit the increase to 1.5 degrees. • Establish binding commitments by all parties to make “nationally determined contributions” (NDCs), and to pursue domestic measures aimed at achieving them. • Commit all countries to report regularly on their emissions and “progress made in implementing and achieving” their NDCs, and to undergo international review. • Commit all countries to submit new NDCs every 5 years, with the clear expectation that they will “represent a progression” beyond previous ones. • Reaffirm the binding obligations of developed countries under the UNFCCC to support the efforts of developing countries, while for the first time encouraging voluntary contributions by developing countries too. • Extend the current goal of mobilizing $100 billion a year in support by 2020 through 2025, with a new, higher goal to be set for the period after 2025. • Extend a mechanism to address “loss and damage” resulting from climate change, which explicitly will not “involve or provide a basis for any liability or compensation.” • Require parties engaging in international emissions trading to avoid “double counting.” • Call for a new mechanism, similar to the Clean Development Mechanism under the Kyoto Protocol, enabling emission reductions in one country to count toward another country’s NDC. On June 1, 2017, President Trump announced the decision for the United States to withdraw from the Paris Climate Accord and the United States officially filed its intent to withdraw on November 4, 2019. Following the 1-year grace period for withdrawal from the Agreement, the United States formally withdrew from the Agreement on November 4, 2020. President Biden rejoined the Agreement on his first day in office, January 20, 2021. The United States officially became a party to the Agreement once again on February 19, 2021, after a mandatory 30-day waiting period.48 Continental Western Climate Initiative (Western North America Cap-and-Trade Program) Cap-and-trade refers to a policy tool where emissions are limited to a certain amount and are tradeable, providing flexibility on how the emitter can comply.

The Endangerment Finding notes that GHGs threaten public health and welfare and are subject to regulation under the Clean Air Act. To date, the EPA has not promulgated regulations on GHG emissions, but it has already begun to develop them. Previously the EPA had not regulated GHGs under the Clean Air Act, because it asserted that the Act did not authorize it to issue mandatory regulations to address global climate change and that such regulation would be unwise without an unequivocally established causal link between GHGs and the increase in global surface air temperatures. In Massachusetts v. Environmental Protection Agency et al. (127 S. Ct. 1438 [2007]); however, the United States Supreme Court held that GHGs are pollutants under the Clean Air Act and directed the EPA to decide whether the gases endangered public health or welfare (see discussion below). The EPA had also not moved aggressively to regulate GHGs because it expected Congress to make progress on GHG legislation, primarily from the standpoint of a cap-and-trade system. However, proposals circulated in both the House of Representatives and the Senate have been controversial and it may be some time before United States Congress adopts major climate change legislation. The EPA’s Endangerment Finding paves the way for federal regulation of GHGs with or without Congress. United States Clean Air Act Permitting Programs (New GHG Source Review) The EPA issued a final rule on May 13, 2010, that establishes thresholds for GHGs that define when permits under the New Source Review Prevention of Significant Deterioration and Title V Operating Permit programs are required for new and existing industrial facilities. This final rule “tailors” the requirements of these Clean Air Act permitting programs to limit which facilities will be required to obtain Prevention of Significant Deterioration and Title V permits. In the preamble to the revisions to the Federal Code of Regulations, the EPA states: This rulemaking is necessary because without it the Prevention of Significant Deterioration and Title V requirements would apply, as of January 2, 2011, at the 100 or 250 tons per year levels provided under the Clean Air Act, greatly increasing the number of required permits, imposing undue costs on small sources, overwhelming the resources of permitting authorities, and severely impairing the functioning of the programs. EPA is relieving these resource burdens by phasing in the applicability of 49 Western Climate Initiative, Inc. 2017. Program Design. Website: http://www.wci-inc.org/program-design.php.

This rule establishes two initial steps of the phase in. The rule also commits the agency to take certain actions on future steps addressing smaller sources, but excludes certain smaller sources from Prevention of Significant Deterioration and Title V permitting for greenhouse gas emissions until at least April 30, 2016. The EPA estimates that facilities responsible for nearly 70 percent of the national GHG emissions from stationary sources will be subject to permitting requirements under this rule. This includes the nation’s largest GHG emitters—power plants, refineries, and cement production facilities. Energy Independence and Security Act The Energy Policy Act of 2005 created the Renewable Fuel Standard program. The Energy Independence and Security Act of 2007 expanded this program by: • Expanding the Renewable Fuel Standard program to include diesel in addition to gasoline. • Increasing the volume of renewable fuel required to be blended into transportation fuel from 9 billion gallons in 2008 to 36 billion gallons by 2022. • Establishing new categories of renewable fuel, and setting separate volume requirements for each one. • Requiring the EPA to apply lifecycle GHG performance threshold standards to ensure that each category of renewable fuel emits fewer GHGs than the petroleum fuel it replaces. This expanded Renewable Fuel Standard program lays the foundation for achieving substantial reductions of GHG emissions from the use of renewable fuels, reducing the use of imported petroleum, and encouraging the development and expansion of the nation’s renewable fuels sector. Signed on December 19, 2007, by President George W. Bush, the Energy Independence and Security Act (EISA) of 2007 aims to: • Move the United States toward greater energy independence and security. • Increase the production of clean renewable fuels. • Protect consumers. • Increase the efficiency of products, buildings, and vehicles. • Promote research on and deploy GHG capture and storage options. • Improve the energy performance of the federal government. • Increase U.S. energy security, develop renewable fuel production, and improve vehicle fuel economy. EISA reinforces the energy reduction goals for federal agencies put forth in Executive Order 13423, as well as introduces requirements that are more aggressive.

The EPA is committed to developing, implementing, and revising both regulations and voluntary programs under the following subtitles in EISA, among others: • Increased Corporate Average Fuel Economy Standards • Federal Vehicle Fleets • Renewable Fuel Standard • Biofuels Infrastructure • Carbon Capture and Sequestration 50 The EPA and National Highway Traffic Safety Administration Light-Duty Vehicle Greenhouse Gas Emission Standards and Corporate Average Fuel Economy Standards Final Rule Congress first passed the Corporate Average Fuel Economy law in 1975 to increase the fuel economy of cars and light-duty trucks. The law has become more stringent over time. On May 19, 2009, the President put in motion a new national policy to increase fuel economy for all new cars and trucks sold in the United States. On April 1, 2010, the EPA and the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) announced a joint final rule establishing a national program that would reduce GHG emissions and improve fuel economy for new cars and trucks sold in the United States. The first phase of the national program would apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles, covering model years 2012 through 2016. They require these vehicles to meet an estimated combined average emissions level of 250 grams of CO2 per mile, equivalent to 35.5 miles per gallon if the automobile industry were to meet this CO2 level solely through fuel economy improvements. Together, these standards would cut CO2 emissions by an estimated 960 MMT and 1.8 billion barrels of oil over the lifetime of the vehicles sold under the program (model years 2012-2016). The EPA and the NHTSA issued final rules on a second phase joint rulemaking, establishing national standards for light-duty vehicles for model years 2017 through 2025 in August 2012.51 The new standards for model years 2017 through 2025 apply to passenger cars, light-duty trucks, and medium-duty passenger vehicles. The final standards are projected to result in an average industry fleet wide level of 163 grams/mile of CO2 in model year 2025, which is equivalent to 54.5 miles per gallon (mpg) if achieved exclusively through fuel economy improvements. The EPA and NHTSA issued final rules for the first national standards to reduce GHG emissions and improve fuel efficiency of heavy-duty trucks and buses on September 15, 2011, which became effective November 14, 2011. For combination tractors, the agencies are proposing engine and vehicle standards that began in the 2014 model year and achieve up to a 20 percent reduction in CO2 50 United States Environmental Protection Agency (EPA). 2019.

For heavy-duty pickup trucks and vans, the agencies are proposing separate gasoline and diesel truck standards, which phase in starting in the 2014 model year and achieve up to a 10 percent reduction for gasoline vehicles, and a 15 percent reduction for diesel vehicles by 2018 model year (12 and 17 percent respectively if accounting for air conditioning leakage). Lastly, for vocational vehicles, the engine and vehicle standards would achieve up to a 10 percent reduction in fuel consumption and CO2 emissions from the 2014 to 2018 model years. The State of California has received a waiver from the EPA to have separate, stricter Corporate Average Fuel Economy Standards. Although global climate change did not become an international concern until the 1980s, efforts to reduce energy consumption began in California in response to the oil crisis in the 1970s, resulting in the incidental reduction of GHG emissions. In order to manage the State’s energy needs and promote energy efficiency, AB 1575 created the California Energy Commission (CEC) in 1975. Massachusetts et al. v. EPA (U.S. Supreme Court GHG Endangerment Ruling) Massachusetts et al. v. EPA (Supreme Court Case 05-1120) was argued before the United States Supreme Court on November 29, 2006, in which it was petitioned that the EPA regulate four GHGs, including CO2, under Section 202(a)(1) of the Clean Air Act (CAA). The Supreme Court decided on April 2, 2007, that GHGs are air pollutants covered by the CAA. The Court held that the Administrator must determine whether emissions of GHGs from new motor vehicles cause or contribute to air pollution, which may reasonably be anticipated to endanger public health or welfare, or whether the science is too uncertain to make a reasoned decision. On December 7, 2009, the EPA Administrator signed two distinct findings regarding GHGs under Section 202(a) of the CAA: • Endangerment Finding: The Administrator finds that the current and projected concentrations of the six key well-mixed GHGs—CO2, CH4, N2O, HFCs, PFCs, and SF6—in the atmosphere threaten the public health and welfare of current and future generations; and • Cause or Contribute Finding: The Administrator finds that the combined emissions of these well-mixed GHGs from new motor vehicles and new motor vehicle engines contribute to the GHG pollution, which threatens public health and welfare. These findings do not impose requirements on industry or other entities. However, this was a prerequisite for implementing GHG emissions standards for vehicles, as discussed under “Clean Vehicles” below. After a lengthy legal challenge, the United States Supreme Court declined to review an Appeals Court ruling upholding that upheld the EPA Administrator findings. United States Consolidated Appropriations Act (Mandatory GHG Reporting) The Consolidated Appropriations Act of 2008, passed in December 2007, requires the establishment of mandatory GHG reporting requirements. On September 22, 2009, the EPA issued the Final Mandatory Reporting of Greenhouse Gases Rule, which became effective January 1, 2010. The rule requires reporting of GHG emissions from large sources and suppliers in the United States, and intends to collect accurate and timely emissions data to inform future policy decisions. Under the rule, suppliers of fossil fuels or industrial GHGs, manufacturers of vehicles and engines, and facilities Contra Costa County—Oak Road Townhouse Condominimums Project Draft EIR Greenhouse Gas Emissions FirstCarbon Solutions 3.7-25 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-07 GHG.docx that emit 25,000 MT or more per year of GHG emissions are required to submit annual reports to the EPA. The first annual reports for the largest emitting facilities, covering calendar year 2010, were submitted to the EPA in 2011. State California AB 1493: Pavley Regulations and Fuel Efficiency Standards California AB 1493, enacted on July 22, 2002, required the ARB to develop and adopt regulations that reduce GHGs emitted by passenger vehicles and light-duty trucks. Implementation of the regulation was delayed by lawsuits filed by automakers and by the EPA’s denial of an implementation waiver. The EPA subsequently granted the requested waiver in 2009, which was upheld by the by the United States District Court for the District of Columbia in 2011.52 The standards are to be phased in during the 2009 through 2016 model years. When fully phased in, the near-term (2009–2012) standards will result in an approximately 22 percent reduction compared with the 2002 fleet, and the mid-term (2013–2016) standards will result in about a 30 percent reduction. Several technologies stand out as providing significant reductions in emissions at favorable costs. These include discrete variable valve lift or camless valve actuation to optimize valve operation rather than relying on fixed valve timing and lift as has historically been done; turbocharging to boost power and allow for engine downsizing; improved multi-speed transmissions; and improved air conditioning systems that operate optimally, leak less, and/or use an alternative refrigerant.53 Amendments to the Low Emission Vehicle (LEV) Program, referred to as LEV III or the Advanced Clean Cars program, incorporated the second phase of implementation for the Pavley Bill. The Advanced Clean Car program combines the control of smog-causing pollutants and GHG emissions into a single coordinated package of requirements for model years 2017 through 2025. The regulation will reduce GHGs from new cars by 34 percent from 2016 levels by 2025. The new rules will reduce pollutants from gasoline and diesel-powered cars, and deliver increasing numbers of zero emission technologies, such as full battery electric cars, newly emerging plug-in hybrid electric vehicles and hydrogen fuel cell cars. The regulations will also ensure adequate fueling infrastructure is available for the increasing numbers of hydrogen fuel cell vehicles planned for deployment in California.54 California Executive Order S-3-05 (GHG Emissions Reduction Targets) Former California Governor Arnold Schwarzenegger announced on June 1, 2005, through Executive Order S-3-05, the following reduction targets for GHG emissions: • By 2010, reduce GHG emissions to 2000 levels. • By 2020, reduce GHG emissions to 1990 levels. • By 2050, reduce GHG emissions to 80 percent below 1990 levels. 52 California Air Resources Board (ARB). 2017.

The 2020 goal was established to be a mid-term target. Because this is an Executive Order, the goals are not legally enforceable for local governments or the private sector. California AB 32: Global Warming Solutions Act and Scoping Plan The California State Legislature enacted AB 32, the California Global Warming Solutions Act of 2006. AB 32 requires that GHGs emitted in California be reduced to 1990 levels by the year 2020. “Greenhouse gases” as defined under AB 32 include CO2, CH4, N2O, HFCs, PFCs, and SF6. Since enactment of AB 32, a seventh chemical, nitrogen trifluoride, has also been added to the list of GHGs. The ARB is the State agency charged with monitoring and regulating sources of GHGs. AB 32 states the following: Global warming poses a serious threat to the economic well-being, public health, natural resources, and the environment of California. The potential adverse impacts of global warming include the exacerbation of air quality problems, a reduction in the quality and supply of water to the State from the Sierra snowpack, a rise in sea levels resulting in the displacement of thousands of coastal businesses and residences, damage to marine ecosystems and the natural environment, and an increase in the incidences of infectious diseases, asthma, and other human health-related problems. The ARB approved the 1990 GHG emissions level of 427 MMT CO2e on December 6, 2007.55 Therefore, to meet the State’s target, emissions generated in California in 2020 are required to be equal to or less than 427 MMT CO2e. Emissions in 2020 in a business-as-usual (BAU) scenario were estimated to be 596 MMT CO2e, which do not account for reductions from AB 32 regulations.56 At that rate, a 28 percent reduction was required to achieve the 427 MMT CO2e 1990 inventory. In October 2010, the ARB prepared an updated 2020 forecast to account for the effects of the 2008 recession and slower forecasted growth. The 2020 inventory without the benefits of adopted regulation is now estimated at 545 MMT CO2e. Therefore, under the updated forecast, a 21.7 percent reduction from BAU is required to achieve 1990 levels.57 The State has made steady progress in implementing AB 32 and achieving targets included in Executive Order S-3-05. Updated emission inventories prepared by the ARB for 2000 through 2012 demonstrate progress achieved to date.58 The State has also achieved the Executive Order S-3-05 target for 2010 of reducing GHG emissions to 2000 levels. As shown below, the 2010 emission inventory achieved this target. Also shown are the average reductions needed from all Statewide sources (including all existing sources) to reduce GHG emissions back to 1990 levels. • 1990: 427 million MT CO2e (AB 32 2020 Target) • 2000: 463 million MT CO2e (an average 8 percent reduction needed to achieve 1990 base) 55 California Air Resources Board (ARB). 2007.

Most of the measures target the transportation and electricity sectors. As stated in the Scoping Plan, the key elements of the strategy for achieving the 2020 GHG target include: • Expanding and strengthening existing energy efficiency programs as well as building and appliance standards. • Achieving a Statewide renewables energy mix of 33 percent. • Developing a California Cap-and-Trade Program that links with other Western Climate Initiative partner programs to create a regional market system. • Establishing targets for transportation-related GHG emissions for regions throughout California and pursuing policies and incentives to achieve those targets. • Adopting and implementing measures pursuant to existing State laws and policies, including California’s clean car standards, goods movement measures, and the Low Carbon Fuel Standard. • Creating targeted fees, including a public goods charge on water use, fees on high global warming potential gases, and a fee to fund the administrative costs of the State’s long-term commitment to AB 32 implementation. In addition, the Scoping Plan differentiates between “capped” and “uncapped” strategies. Capped strategies are subject to the proposed Cap-and-Trade Program. The Scoping Plan states that the inclusion of these emissions within the cap-and trade program will help to meet 2020 emission targets despite some degree of uncertainty in the emission reduction estimates for any individual measure. Calculated implementation of the capped strategies should achieve a sufficient amount of reductions by 2020 to meet the emission target contained in AB 32. Uncapped strategies that will not be subject to the cap-and-trade emissions requirements provide a margin of safety by accounting for additional GHG emission reductions.60 The ARB approved the First Update to the Scoping Plan (Update) on May 22, 2014. The Update identifies the next steps for California’s climate change strategy. The Update shows how California continues on its path to meet the near-term 2020 GHG limit, but also sets a path toward long-term, deep GHG emission reductions. The report establishes a broad framework for continued emission reductions beyond 2020, on the path to 80 percent below 1990 levels by 2050.

The Update does not set new targets for the State, but describes a path that would achieve the long-term 2050 goal of Executive Order S-05- 03 for emissions to decline to 80 percent below 1990 levels by 2050. AB 32 does not give the ARB a legislative mandate to set a target beyond the 2020 target from AB 32 or to adopt additional regulations to achieve a post-2020 target. The Update estimates that reductions averaging 5.2 percent per year would be required after 2020 to achieve the 2050 goal. With no estimate of future reduction commitments from the State, identifying a feasible strategy including plans and measures for adoption by local agencies is not currently possible.61 The Cap-and-Trade Program is a key element of the Scoping Plan. It sets a Statewide limit on sources responsible for 85 percent of California’s GHG emissions, and establishes a price signal needed to drive long-term investment in cleaner fuels and more efficient use of energy. The program is designed to provide covered entities the flexibility to seek out and implement the lowest cost options to reduce emissions. The program conducted its first auction in November 2012. Compliance obligations began for power plants and large industrial sources in January 2013. Other significant milestones include linkage to Québec’s Cap-and-Trade system in January 2014 and starting the compliance obligation for distributors of transportation fuels, natural gas, and other fuels in January 2015.62 The Cap-and-Trade Program provides a firm cap, ensuring that the 2020 Statewide emission limit will not be exceeded. An inherent feature of the Cap-and-Trade Program is that it does not guarantee GHG emissions reductions in any discrete location or by any particular source. Rather, the program only guarantees GHG emissions reductions on a cumulative basis. As summarized by the ARB in the First Update: The Cap-and-Trade Regulation gives companies the flexibility to trade allowances with others or take steps to cost-effectively reduce emissions at their own facilities. Companies that emit more have to turn in more allowances or other compliance instruments. Companies that can cut their GHG emissions have to turn in fewer allowances. But as the cap declines, aggregate emissions must be reduced. In other words, a covered entity theoretically could increase its GHG emissions every year and still comply with the Cap-and-Trade Program if there is a reduction in GHG emissions from other covered entities. Such a focus on aggregate GHG emissions is considered appropriate because climate change is a global phenomenon, and the effects of GHG emissions are considered cumulative.63 The Cap-and-Trade Program works with other direct regulatory measures and provides an economic incentive to reduce emissions. If California’s direct regulatory measures reduce GHG emissions more 61 California Air Resources Board (ARB). 2014. First Update to the Climate Change Scoping Plan.

If California’s direct regulatory measures reduce GHG emissions less than expected, then the Cap-and-Trade Program will be responsible for relatively more emissions reductions. Thus, the Cap-and-Trade Program assures that California will meet its 2020 GHG emissions reduction mandate: The Cap-and-Trade Program establishes an overall limit on GHG emissions from most of the California economy—the “capped sectors.” Within the capped sectors, some of the reductions are being accomplished through direct regulations, such as improved building and appliance efficiency standards, the [Low Carbon Fuel Standard] LCFS, and the 33 percent [Renewables Portfolio Standard] RPS. Whatever additional reductions are needed to bring emissions within the cap is accomplished through price incentives posed by emissions allowance prices. Together, direct regulation and price incentives assure that emissions are brought down cost-effectively to the level of the overall cap. The Cap-and-Trade Regulation provides assurance that California’s 2020 limit will be met because the regulation sets a firm limit on 85 percent of California’s GHG emissions. In sum, the Cap-and-Trade Program will achieve aggregate, rather than site specific or project-level, GHG emissions reductions. Also, due to the regulatory architecture adopted by ARB in AB 32, the reductions attributed to the Cap-and-Trade Program can change over time depending on the State’s emissions forecasts and the effectiveness of direct regulatory measures.64 California Senate Bill 375: Sustainable Communities and Climate Protection Act SB 375 became law on September 30, 2008. According to SB 375, the transportation sector is the largest contributor of GHG emissions, which emits over 40 percent of the total GHG emissions in California. SB 375 states, “Without improved land use and transportation policy, California will not be able to achieve the goals of AB 32.” SB 375 does the following: (1) requires metropolitan planning organizations to include sustainable community strategies in their regional transportation plans for reducing GHG emissions, (2) aligns planning for transportation and housing, and (3) creates specified incentives for the implementation of the strategies. Concerning California Environmental Quality Act (CEQA), SB 375, as codified in Public Resources Code Section 21159.28, states that CEQA determinations for certain projects are not required to reference, describe, or discuss (1) growth inducing impacts or (2) any project-specific or cumulative impacts from cars and light-duty truck trips generated by the project on global warming or the regional transportation network if the project: 1. Is in an area with an approved sustainable communities strategy or an alternative planning strategy that ARB accepts as achieving the GHG emission reduction targets. 2. Is consistent with that strategy (in designation, density, building intensity, and applicable policies). 3. Incorporates the mitigation measures required by an applicable prior environmental document. 64 Ibid.

SB 1368 directs the California Public Utilities Commission to adopt a performance standard for GHG emissions for the future power purchases of California utilities. SB 1368 seeks to limit carbon emissions associated with electrical energy consumed in California by forbidding procurement arrangements for energy longer than 5 years from resources that exceed the emissions of a relatively clean, combined cycle natural gas power plant. Because of the carbon content of its fuel source, a coal-fired plant cannot meet this standard because such plants emit roughly twice as much carbon as natural gas, combined cycle plants. Accordingly, the new law effectively prevents California’s utilities from investing in, otherwise financially supporting, or purchasing power from new coal plants located in or out of the State. The California Public Utilities Commission adopted the regulations required by SB 1368 on August 29, 2007. The regulations implementing SB 1368 establish a standard for baseload generation owned by, or under long-term contract to publicly owned utilities, of 1,100 pounds of CO2 per megawatt-hour (MWh). California Executive Order S-01-07: Low Carbon Fuel Standard The Governor signed Executive Order S 01-07 on January 18, 2007. The Executive Order mandated that a Statewide goal be established to reduce the carbon intensity of California’s transportation fuels by at least 10 percent by 2020. In particular, the Executive Order established a Low Carbon Fuel Standard (LCFS) and directed the Secretary for Environmental Protection to coordinate the actions of the CEC, ARB, the University of California, and other agencies to develop and propose protocols for measuring the “lifecycle carbon intensity” of transportation fuels. This analysis supporting development of the protocols was included in the State Implementation Plan for alternative fuels (State Alternative Fuels Plan adopted by CEC on December 24, 2007) and was submitted to the ARB for consideration as an “early action” item under AB 32. The ARB adopted the LCFS on April 23, 2009. The LCFC was subject to legal challenge in 2011. Ultimately, on August 8, 2013, the Fifth District Court of Appeal (California) ruled that the ARB failed to comply with CEQA and the Administrative Procedure Act when adopting regulations for Low Carbon Fuel Standards. In a partially published opinion, the Court of Appeal directed that Resolution 09-31 and two executive orders of the ARB approving LCFS regulations promulgated to reduce GHG emissions be set aside. However, the Court tailored its remedy to protect the public interest by allowing the LCFS regulations to remain operative while the ARB complies with the procedural requirements it failed to satisfy. To address the Court ruling, the ARB was required to bring a new LCFS regulation to the Board for consideration in February 2015. The proposed LCFS regulation was required to contain revisions to the 2010 LCFS as well as new provisions designed to foster investments in the production of the low carbon fuels, offer additional flexibility to regulated parties, update critical technical information, simplify and streamline program operations, and enhance enforcement. The second public hearing for the new LCFS regulation occurred on September 24 and 25, 2015, where the LCFS regulation was adopted. The Final Rulemaking Package adopting the regulation was filed with the Office of Administrative Law (OAL) on October 2, 2015. The OAL approved the regulation on November 16, 2015.65 65 California Air Resources Board (ARB). 2015. Low Carbon Fuel Standard Regulation. November 20.

California SBX 7-7: Water Conservation Act This 2009 legislation directs urban retail water suppliers to set individual 2020 per capita water use targets and begin implementing conservation measures to achieve those goals. Meeting this Statewide goal of 20 percent decrease in demand will result in a reduction of almost 2 million acre- feet in urban water use in 2020. California SB 97 and the CEQA Guidelines Update Passed in August 2007, SB 97 added Section 21083.05 to the Public Resources Code. The Code states “(a) On or before July 1, 2009, the Office of Planning and Research shall prepare, develop, and transmit to the Resources Agency guidelines for the mitigation of GHG emissions or the effects of GHG emissions as required by this division including but not limited to, effects associated with transportation or energy consumption. (b) On or before January 1, 2010, the Resources Agency shall certify and adopt guidelines prepared and developed by the Office of Planning and Research pursuant to subdivision (a).” Section 21097 was also added to the Public Resources Code, providing an exemption until January 1, 2010, for transportation projects funded by the Highway Safety, Traffic Reduction, Air Quality, and Port Security Bond Act of 2006, or projects funded by the Disaster Preparedness and Flood Prevention Bond Act of 2006, by stating that failure to analyze adequately the effects of GHGs would not violate CEQA. The Natural Resources Agency completed the approval process, and the Amendments became effective on March 18, 2010. The 2010 CEQA Amendments provide guidance to public agencies regarding the analysis and mitigation of the effects of GHG emissions in CEQA documents. The CEQA Amendments fit within the existing CEQA framework by amending existing CEQA Guidelines to reference climate change. Section 15064.4(b) of the CEQA Guidelines provides direction for lead agencies for assessing the significance of impacts of GHG emissions: • The extent to which the project may increase or reduce GHG emissions as compared to the existing environmental setting. • Whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project. Contra Costa County—Oak Road Townhouse Condominimums Project Greenhouse Gas Emissions Draft EIR 3.7-32 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-07 GHG.docx • The extent to which the project complies with regulations or requirements adopted to implement a Statewide, regional, or local plan for the reduction or mitigation of GHG emissions. Such regulations or requirements must be adopted by the relevant public agency through a public review process and must include specific requirements that reduce or mitigate the project’s incremental contribution of GHG emissions. If there is substantial evidence that the possible effects of a particular project are still cumulatively considerable notwithstanding compliance with the adopted regulations or requirements, an EIR must be prepared for the project. The CEQA Guidelines amendments do not identify a threshold of significance for GHG emissions, nor do they prescribe assessment methodologies or specific mitigation measures. Instead, they call for a “good-faith effort, based on available information, to describe, calculate, or estimate the amount of greenhouse gas emissions resulting from a project.” The amendments encourage lead agencies to consider many factors in performing a CEQA analysis and preserve lead agencies’ discretion to make their own determinations based upon substantial evidence. The amendments also encourage public agencies to make use of programmatic mitigation plans and programs from which to tier when they perform individual project analyses. Also amended were CEQA Guidelines Sections 15126.4 and 15130, which address mitigation measures and cumulative impacts, respectively. GHG mitigation measures are referenced in general terms, but no specific measures are championed. The revision to the cumulative impact discussion requirement (Section 15130) simply directs agencies to analyze GHG emissions in an EIR when a project’s incremental contribution of emissions may be cumulatively considerable; however, it does not answer the question of when emissions are cumulatively considerable. Section 15183.5 permits programmatic GHG analysis and later project-specific tiering, as well as the preparation of GHG Reduction Plans. Compliance with such plans can support a determination that a project’s cumulative effect is not cumulatively considerable, according to Section 15183.5(b). In addition, the 2010 CEQA amendments revised Appendix F of the CEQA Guidelines, which focuses on Energy Conservation. The sample environmental checklist in CEQA Guidelines Appendix G was amended to include GHG questions. The most recent sample environmental checklist in Appendix G was further amended in 2018 to include two energy questions. CEQA emphasizes that the effects of GHG emissions are cumulative, and should be analyzed in the context of CEQA’s requirements for cumulative impacts analysis (CEQA Guidelines § 15130(f)). Center for Biological Diversity v. California Department of Fish and Wildlife (California Supreme Court GHG Ruling) In a November 30, 2015, ruling, the California Supreme Court in Center for Biological Diversity (CBD) v. California Department of Fish and Wildlife (CDFW) on the Newhall Ranch project concluded that whether the project was consistent with meeting Statewide emission reduction goals is a legally permissible criterion of significance, but the significance finding for the project was not supported by a reasoned explanation based on substantial evidence. The Court offered potential solutions on pages 25–27 of the ruling to address this issue summarized below: Contra Costa County—Oak Road Townhouse Condominimums Project Draft EIR Greenhouse Gas Emissions FirstCarbon Solutions 3.7-33 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-07 GHG.docx Specifically, the Court advised that: • Substantiation of Project Reductions from BAU. A lead agency may use a BAU comparison based on the Scoping Plan’s methodology if it also substantiates the reduction a particular project must achieve to comply with Statewide goals. The Court suggested a lead agency could examine the “data behind the Scoping Plan’s business-as-usual model” to determine the necessary project- level reductions from new land use development at the proposed location (p. 25). • Compliance with Regulatory Programs or Performance Based Standards. A lead agency “might assess consistency with AB 32’s goal in whole or part by looking to compliance with regulatory programs designed to reduce greenhouse gas emissions from particular activities. (See Final Statement of Reasons, supra, at p. 64 [greenhouse gas emissions ‘may be best analyzed and mitigated at a programmatic level.’])” To the extent a project’s design features comply with or exceed the regulations outlined in the Scoping Plan and adopted by the Air Resources Board or other State agencies, a lead agency could appropriately rely on their use as showing compliance with ‘performance based standards’ adopted to fulfill ‘a statewide . . . plan for the reduction or mitigation of greenhouse gas emissions’ (CEQA Guidelines § 15064.4(a)(2), (b)(3); see also id., § 15064(h)(3) [determination that impact is not cumulatively considerable may rest on compliance with previously adopted plans or regulations, including ‘plans or regulations for the reduction of greenhouse gas emissions’]) (p. 26). • Compliance with GHG Reduction Plans or CAPs. A lead agency may utilize “geographically specific GHG emission reduction plans” such as climate action plans or GHG emission reduction plans to provide a basis for the tiering or streamlining of project-level CEQA analysis (p. 26). • Compliance with Local Air District Thresholds. A lead agency may rely on “existing numerical thresholds of significance for greenhouse gas emissions” adopted by, for example, local air districts (p. 27). Therefore, consistent with 2019 CEQA Guidelines Appendix G, the three factors identified in CEQA Guidelines Section 15064.4 and the recently issued Newhall Ranch opinion, the GHG impacts would be considered significant if the project would: • Conflict with a compliant GHG Reduction Plan if adopted by the lead agency. • Exceed the applicable GHG Reduction Threshold. • Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emission of GHGs. California SB 350: Clean Energy and Pollution Reduction Act In 2015, the State Legislature approved, and the Governor signed SB 350, which reaffirms California’s commitment to reducing its GHG emissions and addressing climate change. Key provisions include an increase in the Renewables Portfolio Standard, higher energy efficiency requirements for buildings, initial strategies toward a regional electricity grid, and improved infrastructure for electric vehicle charging stations. Provisions for a 50 percent reduction in the use of petroleum Statewide Contra Costa County—Oak Road Townhouse Condominimums Project Greenhouse Gas Emissions Draft EIR 3.7-34 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-07 GHG.docx were removed from the Bill due to opposition and concern that it would prevent the Bill’s passage. Specifically, SB 350 requires the following to reduce Statewide GHG emissions: • Increase the amount of electricity procured from renewable energy sources from 33 percent to 50 percent by 2030, with interim targets of 40 percent by 2024, and 25 percent by 2027. • Double the energy efficiency in existing buildings by 2030. The California Public Utility Commission, the CEC, and local publicly owned utilities will achieve this target. • Reorganize the Independent System Operator (ISO) to develop regional electricity transmission markets and improve accessibility in these markets, which will facilitate the growth of renewable energy markets in the western United States.66 California Executive Order B-30-15 On April 29, 2015, the Governor issued an Executive Order to establish a California GHG emissions reduction target of 40 percent below 1990 levels by 2030. The Governor’s Executive Order aligns California’s GHG reduction targets with those of leading international governments ahead of the United Nations Climate Change Conference in Paris late 2015. The Executive Order sets a new interim Statewide GHG emission reduction target to reduce GHG emissions to 40 percent below 1990 levels by 2030 in order to ensure California meets its target of reducing GHG emissions to 80 percent below 1990 levels by 2050. It also directs the ARB to update the Climate Change Scoping Plan to express the 2030 target in terms of MM CO2e. Further, the Executive Order requires the State to update its climate adaptation plan every three years and continue its climate change research program, among other provisions. As with Executive Order S-3-05, this Executive Order is not legally enforceable against local governments and the private sector. Legislation that would update AB 32 to make post-2020 targets and requirements a mandate is in process in the State Legislature. California Senate Bill 32 The Governor signed SB 32 in September of 2016, giving the ARB the statutory responsibility to include the 2030 target previously contained in Executive Order B-30-15 in the 2017 Scoping Plan Update. SB 32 states, “In adopting rules and regulations to achieve the maximum technologically feasible and cost-effective greenhouse gas emissions reductions authorized by this division, the state [air resources] board shall ensure that statewide greenhouse gas emissions are reduced to at least 40 percent below the statewide greenhouse gas emissions limit no later than December 31, 2030.” The 2017 Climate Change Scoping Plan Update addressing the SB 32 targets was adopted on December 14, 2017. The major elements of the framework proposed to achieve the 2030 target are as follows: 1. SB 350 • Achieve 50 percent Renewables Portfolio Standard by 2030. • Doubling of energy efficiency savings by 2030. 2. Low Carbon Fuel Standard • Increased stringency (reducing carbon intensity 18 percent by 2030, up from 10 percent in 2020). 66 California State Senate. 2015.

California Code of Regulations Title 24 Part 6 (Energy Efficiency Standards for Residential and Nonresidential Buildings) California Code of Regulations Title 24 Part 6 (California’s Energy Efficiency Standards for Residential and Nonresidential Buildings) was first adopted in 1978 in response to a legislative mandate to reduce California’s energy consumption. The standards are updated periodically to allow consideration and possible incorporation of new energy efficient technologies and methods. Energy efficient buildings require less electricity; therefore, increased energy efficiency reduces fossil fuel consumption and decreases GHG emissions.

The code also provides exemptions for areas not served by construction and demolition recycling infrastructure. State building code provides the minimum standard that buildings must meet to achieve certification for occupancy, which local building officials generally enforce. California Model Water Efficient Landscape Ordinance AB 1881 (the Water Conservation Act) required the Model Water Efficient Landscape Ordinance (Ordinance). The Bill required local agencies to adopt a local landscape ordinance at least as effective in conserving water as the Ordinance by January 1, 2010. Reductions in water use of 20 percent consistent with the 2020 mandate (SBX-7-7) are expected for the Ordinance. Governor Brown’s Drought Executive Order of April 1, 2015 (EO B-29-15) directed the California Department of Water Resources (DWR) to update the Ordinance through expedited regulation. The California Water Commission approved the revised Ordinance on July 15, 2015, which became effective on December 15, 2015. New development projects that include landscaped areas of 500 square feet or more are subject to the Ordinance. The update requires: • More efficient irrigation systems • Incentives for graywater usage • Improvements in on-site stormwater capture • Limiting the portion of landscapes that can be planted with high water use plants • Reporting requirements for local agencies. California Green Building Code The Building Energy Efficiency Standards for Residential and Nonresidential Buildings (California Code of Regulations Title 24, Part 6) were established in 1978 in response to a legislative mandate to reduce California’s energy consumption.

The CAA and CCAA require that plans be developed for areas that do not meet air quality standards. BAAQMD adopted Spare the Air, Cool the Climate (Bay Area Clean Air Plan) on April 19, 2017, to provide a regional strategy to improve Bay Area air quality and meet public health goals.70 The control strategy described in the Bay Area Clean Air Plan includes a wide range of control measures designed to reduce emissions and lower ambient concentrations of harmful pollutants, safeguard public health by reducing exposure to air pollutants that pose the greatest health risk, and reduce GHG emissions to protect the climate. In addition, the BAAQMD established a climate protection program to reduce pollutants that contribute to global climate change and affect air quality in the San Francisco Bay Area Air Basin. The program includes GHG reduction measures that promote energy efficiency, reduce fossil fuel combustion, and decrease emissions of potent GHGs and pollutants.71 The BAAQMD CEQA Air Quality Guidelines also assist lead agencies in complying with CEQA requirements regarding potentially adverse impacts on air quality. The BAAQMD advises lead agencies to consider adopting a GHG reduction strategy capable of meeting AB 32 goals. This is consistent with the approach to analyzing GHG emissions described in State CEQA Guidelines Section 15183.5. Local Contra Costa County General Plan The Contra Costa County General Plan (General Plan) establishes goals, objectives, policies, and implementation measures associated with GHG emissions.72 Those goals, policies, and implementation measures that are relevant to this analysis are listed below.

In addition to reducing GHG emissions, the CAP includes proposed policies and actions to improve public health and provide additional community benefits, and it lays the groundwork for achieving long-term GHG reduction goals for 2020 and 2035. 3.7.4 - Impacts and Mitigation Measures According to CEQA Guidelines Appendix G Environmental Checklist, to determine whether impacts related to GHG emissions are significant environmental effects, the following questions are analyzed and evaluated. Would the proposed project: a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? b) Conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases? Approach to Analysis GHG Emissions Generation Calculation Methodology GHG emissions associated with construction and operation of the proposed project were estimated using the California Emissions Estimator Model (CalEEMod) emissions modeling program and the EMFAC2021 mobile source emission rate program.74 Construction Construction emissions can vary substantially from day to day, depending on the level of activity, the specific type of operation, and prevailing weather conditions. Construction emissions result from on- site and off-site activities. On-site GHG emissions principally consist of exhaust emissions from heavy-duty construction equipment. Off-site GHG emissions would occur from motor vehicle exhaust from material delivery vehicles and construction worker traffic. Operation For operational GHG emissions, the BAAQMD provides three alternative thresholds: • compliance with a qualified Greenhouse Gas Reduction Strategy, • 1,100 MT CO2e per year, or • 4.6 MT CO2e per service population per year. The BAAQMD’s thresholds of significance listed above were established based on meeting the 2020 GHG targets set forth in the AB 32 Scoping Plan.75 AB 32 requires that Statewide GHG emissions be 73 Contra Costa County Department of Conservation and Development and Michael Baker International. 2015.

SB 32 extended California’s GHG reduction programs beyond 2020 and contains language to authorize the ARB to achieve a Statewide GHG emission reduction of at least 40 percent below 1990 levels by December 31, 2030. The ARB approved the 2017 California's Climate Change Scoping Plan update.76 The 2017 Scoping Plan update outlines the proposed framework of action for achieving the 2030 GHG target of 40 percent reduction in GHG emissions relative to 1990 levels. Because the proposed project would be constructed after 2020, the BAAQMD quantitative thresholds of significance listed above was adjusted to a “substantial progress” threshold that was calculated based on the SB 32 target of 40 percent below 1990 levels (i.e., 60 percent of 1990 levels). The mass emission threshold of significance applied in this analysis is 660 MT CO2e per year (1,100 x 0.60 = 660). If operation of the proposed project would generate GHG emissions that exceed the bright-line threshold, the proposed project would need to be analyzed against an appropriate efficiency threshold. According to the County’s CAP, unincorporated County GHG emissions in its 2005 baseline year totaled approximately 1,403,610 MT CO2e/year.77 Consistent with the Governor’s Office of Planning and Research (OPR) guidance on CAP development, the 2005 baseline year should demonstrate a 15 percent reduction by 2020 to be consistent with the reduction targets contained in AB 32 to be representative of 1990 emission levels. A 15 percent reduction would result in an emissions inventory target of approximately 1,193,069 MT CO2e/year. As SB 32 requires a 40 percent reduction from 1990 levels by 2030, unincorporated Contra Costa County would therefore have a GHG emissions inventory target of approximately 715,841 MT CO2e/year. According to the Association of Bay Area Governments’ (ABAG) Plan Bay Area 2040 projections, unincorporated Contra Costa County would have an estimated 184,585 residents and 39,895 jobs in 2030, totaling a 2030 service population of 224,480 persons.78 With a GHG emissions inventory target of approximately 715,841 MT CO2e/year and service population of 224,480 persons in 2030, the efficiency metric for unincorporated Contra Costa County in 2030 would be 3.2 MT CO2e per service population per year. As such, an efficiency threshold of 3.2 MT CO2e per service population per year is utilized in this analysis. The proposed project would have a potentially significant impact if both the bright-line and efficiency thresholds are exceeded. Indirect GHG Emissions For GHG emissions, CalEEMod contains calculations to estimate indirect GHG emissions. Indirect emissions are emissions where the location of consumption or activity is different from where the actual emissions generate. For example, electricity would be consumed at the proposed residences; however, the emissions associated with producing that electricity are generated off-site at a power plant. 76 California Air Resources Board (ARB). 2017.

For water consumption, CalEEMod calculates the embedded energy (e.g., treatment, conveyance, and distribution) associated with providing each gallon of potable water to the project. For solid waste disposal, CalEEMod calculates the GHG emissions generated as solid waste generated by the project decomposes in a landfill. Specific Thresholds of Significance GHG Emissions Generation The County utilizes BAAQMD quantitative thresholds for evaluation of GHG emissions, as applicable. BAAQMD provides multiple options in its 2017 BAAQMD CEQA Guidelines for operational GHG emissions generation significance thresholds. However, at the time of this analysis, BAAQMD has not yet provided a construction-related GHG emissions generation significance threshold but it does recommend that construction-generated GHGs be quantified and disclosed. As previously stated, the proposed project will be analyzed against the BAAQMD-adjusted bright-line threshold to demonstrate consistency with GHG legislative reduction targets codified by SB 32. If the proposed project exceeds the bright-line threshold, it will then be analyzed against the above-mentioned efficiency threshold. The proposed project would have a potentially significant impact if both thresholds are exceeded. GHG Emissions Reduction Plan Consistency The proposed project would be determined to conflict with an applicable GHG emissions reduction plan if it would not adhere to applicable GHG reduction measures included in the Contra Costa County CAP. Impact Evaluation Greenhouse Gas Emissions Impact GHG-1: The proposed project would not generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment. GHG emissions associated with development of the proposed project would occur over the short term from construction activities, consisting primarily of emissions from equipment exhaust and worker and vendor trips. There would also be long-term operational emissions associated with vehicular traffic within the project vicinity, energy and water usage, and solid waste disposal. Emissions for the proposed project are discussed below and were analyzed using the methodology recommended in the BAAQMD CEQA Air Quality Guidelines. CalEEMod was used to predict GHG emissions from operation of the site assuming full buildout of the proposed project. Construction As shown in Table 3.7-4, GHG emissions associated with construction were estimated to be 368 MT of CO2e for the total construction period. These would represent the GHG emissions generated from on-site operation of construction equipment, vendor and hauling truck trips, and worker trips. Neither the County nor BAAQMD have an adopted threshold of significance for construction-related GHG emissions, though BAAQMD recommends quantifying emissions and disclosing that GHG Contra Costa County—Oak Road Townhouse Condominimums Project Greenhouse Gas Emissions Draft EIR 3.7-42 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-07 GHG.docx emissions would occur during construction. BAAQMD also encourages the incorporation of best management practices to reduce GHG emissions during construction where feasible and applicable.

Operation The proposed project would contribute to global climate change through direct and indirect emissions of GHG from transportation sources (passenger vehicles, trucks), energy (natural gas and purchased energy), water use and wastewater generation, and solid waste generation. The CalEEMod model, along with the project vehicle trip generation rates, was used to estimate daily emissions associated with operation of the fully developed site under the proposed project. As the proposed project is residential in nature, it would be required to comply with the standards contained in the 2019 California Building Code, Title 24, Part 6, Subchapter 8, which requires rooftop solar systems for each dwelling units. Therefore, the annual electricity consumption was estimated utilizing the CalEEMod model and the minimum solar system capacity was calculated to determine how much the required solar system would offset the proposed project’s electricity related GHG emissions (Appendix B). According to the CalEEMod model, the proposed project is estimated to consume approximately 635,440 kWh per year, and according to the solar system capacity calculations, the proposed project would generate an estimated 301,400 kWh per year. Therefore, the electricity related GHG emissions estimated for project operation were reduced to reflect the GHG emissions generated from the electricity consumed that would not be covered by the rooftop solar system and are shown below. As shown in Table 3.7-5, the annual GHG emissions resulting from operation of the proposed project are estimated to be 677 MT of CO2e in 2024 and would exceed the 660 MT CO2e/year bright-line threshold. While the proposed project would involve demolition of the existing Palmer School and it is normal practice to include existing emission estimates to demonstrate net GHG emissions resulting from the proposed project, the Palmer School was not in operation at the time the Notice of Preparation (NOP) was issued for this project. Consistent with the BAAQMD’s CEQA Air Quality Guidelines,79 “[t]his net calculation is not permitted for emission sources that ceased to operate, or the land uses 79 Bay Area Air Quality Management District (BAAQMD). 2017.

As illustrated above, the proposed project would result in GHG emissions that would exceed the BAAQMD’s significance threshold adjusted for the 2030 legislative GHG reduction targets codified by SB 32. As a result, the proposed project was analyzed against the efficiency threshold which was calculated to demonstrate consistency with the 40 percent below 1990 emission levels reduction target of SB 32. As shown therein, the proposed project would not exceed the efficiency threshold and would be consistent with the GHG emission reductions required under SB 32. This impact would be less than significant. Level of Significance Less than significant impact. GHG Emissions Reduction Plan Consistency Impact GHG-2: The proposed project would not conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases. The following discusses project consistency with applicable plans adopted for the purpose of reducing GHG emissions, which include ARB’s Scoping Plan and the Contra Costa County CAP. ARB Scoping Plan The ARB Scoping Plan is the State’s strategy to achieve the GHG emissions reduction goals under AB 32 and SB 32, as well as a long-term strategy to achieve the State’s overall carbon neutrality goals for 2050 under Executive Order S-03-05. It is applicable to State agencies but is not directly applicable to cities/counties and individual projects (i.e., the Scoping Plan does not require the County to adopt Contra Costa County—Oak Road Townhouse Condominimums Project Draft EIR Greenhouse Gas Emissions FirstCarbon Solutions 3.7-45 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-07 GHG.docx policies, programs, or regulations to reduce GHG emissions). However, new regulations adopted by the State agencies outlined in the Scoping Plan result in GHG emissions reductions at the local level. As a result, local jurisdictions benefit from reductions in transportation emissions rates, increases in water efficiency in the building and landscape codes, and other Statewide actions that affect a local jurisdiction’s emissions inventory from the top down. Contra Costa County Climate Action Plan The County adopted its CAP on December 15, 2015. The CAP is intended to streamline future environmental review of development projects in the County by following the CEQA Guidelines and meeting the BAAQMD expectations for a qualified GHG reduction strategy through the year 2020. While the County’s CAP is designed to demonstrate consistency with 2020 GHG reduction targets presented by AB 32, it does not incorporate necessary reductions to meet the 2030 GHG reduction targets codified by SB 32. Therefore, the proposed project’s consistency with the County’s CAP is analyzed here to determine whether the proposed project is consistent with the local GHG reduction strategy, instead of utilizing the County’s CAP for CEQA streamlining purposes. The County’s strategy is structured around the following six topic areas: energy efficiency and conservation, renewable energy, land use and transportation, solid waste, water conservation, and government operations. The proposed project incorporates several design elements that would reduce GHG emissions, such as conformance to the 2019 Building Energy Efficiency Standards and CALGreen building regulations and installation of a photovoltaics (PV) system. In addition, a development checklist under the CAP has been filled out for the proposed project to demonstrate compliance. The proposed project would also be consistent with the measures in the CAP, as identified in Table 3.7-7. Table 3.7-7: Contra Costa County Climate Action Plan Consistency Applicable Goals Measures Consistency Analysis Energy Efficiency and Conservation Increase energy efficiency in residential and commercial building stock, and reduce community-wide electricity and natural gas use. EE-1: Provide opportunities for residential buildings to become more energy efficient. Consistent. The proposed project would comply with the California Building Code and the 2019 Building Energy Efficiency Standards. This would improve energy efficiency by 10.7 percent and 1 percent for electricity and natural gas, respectively, compared to the 2016 Building Energy Efficiency Standards. EE-4: Reduce urban heat islands through vegetation management and cool surfaces. Renewable Energy Increase the production of renewable energy from small-scale and commercial- scale renewable energy installations. RE-1: Promote installation of alternative energy facilities on homes and businesses Consistent. The proposed project would install a PV system in accordance with the requirements contained in Title 24, Part 6, Subchapter 8, of the 2019 California Building Code.

RecycleSmart holds franchise agreements with waste franchises that provide solid waste collection and disposal of residential and commercial solid waste. Water Conservation Conserve water. WE-1: Reduce water demand. Consistent. The proposed project would be constructed in conformance with CALGreen and the Title 24 Building Code, which requires high-efficiency water fixtures and water efficient irrigation systems.

Level of Significance Less than significant impact. 3.7.5 - Cumulative Impacts GHG emissions and global climate change inherently represent cumulative impacts. GHG emissions cumulatively contribute to the significant adverse environmental impacts of global climate change. No single project could generate enough GHG emissions to noticeably change the global average temperature; instead, the GHG emissions from past, present, and future projects and activities have contributed to and would contribute to global climate change and its associated environmental impacts. According to the BAAQMD, project GHG emissions are inherently cumulative and do not require the estimation of cumulative projects in the region of the project. Thus, the determination of GHG cumulative impacts is based on the State target established by AB 32 to reduce GHG emissions to 1990 levels by 2020. In order to ensure that this goal would be achieved, Air Districts and Lead Contra Costa County—Oak Road Townhouse Condominimums Project Draft EIR Greenhouse Gas Emissions FirstCarbon Solutions 3.7-47 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-07 GHG.docx Agencies developed GHG thresholds to ensure compliance with the State target. Projects with GHG emissions in conformance with these thresholds, therefore, would not be considered significant for purposes of CEQA. As analyzed in Impact GHG-1, the proposed project would have a GHG emissions benefit when compared to the existing emissions and would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing GHG emissions. Although the emissions from cumulative projects would add an incremental amount to the overall GHG emissions that cause global climate change impacts, emissions from projects consistent with the GHG thresholds would not be a “cumulatively considerable” contribution under CEQA. As such, there would be a less than significant impact related to GHG emissions generation. Level of Cumulative Significance Less than significant impact.

This section also evaluates the possible impacts related to hazards and hazardous materials that could result from implementation of the proposed project. Information included in this section is based on a Phase I Environmental Site Assessment and Phase II Environmental Investigation Report (Phase I ESA and Limited Phase II Investigation) prepared by Roux Associates, Inc. (Roux) in August 2021. This report is included as Appendix F. During the Notice of Preparation (NOP) comment period, the following comment was received related to the proposed project regarding Hazards and Hazardous Materials: • Concern regarding release of asbestos during demolition could cause permanent damage to the community. 3.8.2 - Environmental Setting Fundamentals Hazards This description of existing conditions focuses on hazards from fire and overhead power lines, as well as hazardous materials and wastes. A hazard is a situation that poses a level of threat to life, health, property, or the environment. Hazards can be dormant or potential, with only a theoretical risk of harm. However, once a hazard becomes active, it can create an emergency. A hazardous situation that has already occurred is called an incident. Emergency response is action taken in response to an unexpected and dangerous occurrence in an attempt to mitigate its impact on people, structures, or the environment. Emergency situations can range from natural disasters to hazardous materials problems and transportation incidents. Hazards Materials and Wastes Hazardous materials include but are not limited to hazardous materials, hazardous substances, and hazardous wastes, as defined in Section 25501 and Section 25117, respectively, of the California Health and Safety Code. A hazardous material is any material that, because of its quantity, concentration, or physical or chemical characteristics, poses a significant present or potential hazard to human health and safety, or to the environment, if released; and any material that a handler or an administering regulatory agency under Health and Safety Code Section 25501 has a reasonable basis for believing would be injurious to the health and safety of persons or harmful to the environment. Various properties of a substance may cause that substance to be considered hazardous, including: • Toxicity—causes human health effects; • Ignitability—has the ability to burn; • Corrosivity—causes severe burns or damage to materials; and • Reactivity—causes explosions or generates toxic gases. Contra Costa County–Oak Road Townhouse Condominiums Project Hazards and Hazardous Materials Draft EIR 3.8-2 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-08 Hazards.docx Hazardous Building Materials Many older buildings contain building materials consisting of hazardous materials. These materials include lead-based paint (LBP), asbestos-containing material (ACM), and polychlorinated biphenyls (PCBs). Prior to the United States Environmental Protection Agency (EPA) ban in 1978, LBP was commonly used on interior and exterior surfaces of buildings. Disturbances such as sanding and scraping activities, renovation work, gradual wear and tear, old peeling paint, and paint dust particulates have been found to contaminate surface soils or cause lead dust to migrate and affect indoor air quality. Exposure to residual lead can cause severe health effects, especially in children. Asbestos is a naturally occurring fibrous material that was extensively used as a fireproofing and insulating agent in building construction materials before such uses were banned by the EPA in the 1970s. In addition, many types of electrical equipment contained PCBs as an insulator, including transformers and capacitors. After PCBs were determined to be a carcinogen in the mid to late 1970s, the EPA banned PCB use in new equipment and began a program to phase out certain existing PCB-containing equipment. For example, fluorescent lighting ballasts manufactured after January 1, 1978, do not contain PCBs, and are required to have a label clearly stating that PCBs are not present in the unit. Hazardous Substances A hazardous substance can be any biological, natural, or chemical substance, whether solid, liquid, or gas, which may cause harm to human health. Hazardous substances are classified based on their potential health effects, whether acute (immediate) or chronic (long-term). Dangerous goods are classified based on immediate physical or chemical effects, such as fire, explosion, corrosion, and poisoning. An accident involving dangerous goods could seriously harm human health or damage property or the environment. Harm to human health may happen suddenly (acute), such as dizziness, nausea, and itchy eyes or skin; or it may happen gradually over years (chronic), such as dermatitis or cancer. Some people can be more susceptible than others. Hazardous substances and dangerous goods can include antiseptic used for a cut, paint for walls, a cleaning product for the bathroom, chlorine in a pool, carbon monoxide from a motor vehicle, fumes from welding, vapors from adhesives, or dust from cement, stone, or rubber operations. Such hazardous substances can make humans very sick if they are not used properly. Hazardous Wastes Hazardous waste is any hazardous material that is to be discarded, abandoned, or recycled. The criteria that define a material as hazardous also define a waste as hazardous. Specifically, materials and waste may be considered hazardous if they are poisonous (toxic); can be ignited by open flame (ignitable); corrode other materials (corrosive); or react violently, explode, or generate vapors when mixed with water (reactive). Soil or groundwater contaminated with hazardous materials above specified regulatory State or federal thresholds is considered hazardous waste if it is removed from a site for disposal. If handled, disposed, or otherwise handled improperly, hazardous materials and hazardous waste can result in public health hazards if released into the soil or groundwater or through airborne releases in vapors, fumes, or dust. Soil and groundwater having concentrations of hazardous constituents higher than specific regulatory levels must be handled and disposed of as Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Hazards and Hazardous Materials FirstCarbon Solutions 3.8-3 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-08 Hazards.docx hazardous waste when excavated or pumped from an aquifer. The California Code of Regulations, Title 22, Sections 66261.20–24 contains technical descriptions of toxic characteristics that could cause soil or groundwater to be classified as hazardous waste. Hazardous Materials Listing The Cortese List is a list of known hazardous materials or hazardous waste facilities that meet one or more of the provisions of Government Code Section 65962.5, including: • The list of hazardous waste and substances sites from the California Department of Toxic Substances Control (DTSC) EnviroStor database.1 • The list of Leaking Underground Storage Tank (LUST) sites by County and fiscal year from the California State Water Resources Control Board (State Water Board) GeoTracker database.2 • The list of solid waste disposal sites identified by the State Water Board with waste constituents exceeding hazardous waste levels outside the waste management unit.3 • The list of active cease-and-desist orders and cleanup and abatement orders from the State Water Board.4 • The list of hazardous waste facilities subject to corrective action under Section 25187.5 of the Health and Safety Code, as identified by the DTSC.5 Existing Fire-related Conditions and Presence of Hazardous Materials Hazards in the County and project area discussed in this section are primarily related to fire and hazardous materials. Fire hazards and hazardous materials are typically site-specific, so existing conditions related to fire hazards and the transport, use, and disposal of hazardous materials are discussed below under “project site.” Fire hazards present a considerable problem to vegetation and wildlife habitats throughout the County. Grassland fires easily ignite, particularly in dry seasons. These fires are relatively easily controlled if they can be reached by fire equipment; the burned slopes, however, are highly subject to erosion and gullying. While brushlands are naturally adapted to frequent light fires, fire protection in recent decades has resulted in heavy fuel accumulation on the ground. Wildfire is a serious hazard in undeveloped areas and on large lot home sites with extensive areas of unirrigated vegetation, particularly near areas of natural vegetation and steep slopes, since fires tend to burn more rapidly on steeper terrain. Wildfire is also a serious hazard in areas of high wind, given that fires will travel faster and farther geographically when winds are higher. 1 California Department of Toxic Substances Control (DTSC).

These heavy industrial uses present potential risks to public safety due to explosion and flammability of petroleum and chemical materials.6 In addition, storage tanks and pipelines are located throughout the County and could present public safety risks due to geologic conditions. The County does not designate any routes for hazardous material transportation.7 Hazardous materials such as asbestos and lead are also likely present in building materials and paints in older structures. Emergency response in the County is coordinated by the Contra Costa County Fire Protection District (CCCFPD). The CCCFPD provides response services to hazardous materials incidents, as well as fire protection and emergency medical services, as discussed further in Section 3.13, Public Services and Recreation. Project Site In 2021, a Phase I ESA and Limited Phase II Investigation was prepared by Roux Environmental Consulting and Management (Roux) for the project site in accordance with the American Society of Testing and Materials (ASTM) Standard E 1527-13 and the EPA’s All Appropriate Inquiries rule adopted November 2013 (Appendix F).8 Roux reviewed prior site investigation documents, aerial photographs, topographic maps, Sanborn fire insurance maps, and agency files. Roux reviewed records available at local and regional public agencies through website research, office visits, telephone or written contacts, and environmental database searches. Roux interviewed knowledgeable persons about the site and conducted a site reconnaissance on July 31, 2020, to observe existing property conditions, including the presence of hazardous materials and/or wastes. The findings of these reviews and interviews lead Roux to identify one Recognized Environmental Conditions (REC) and two Business Environmental Risks (BERs) at the project site. Finally, to assess the REC and one of the BERs, Roux conducted subsurface investigations between August and December 2020.9 Databases searches did not yield records of underground storage tanks (USTs) or LUSTs. However, the project site owner, who escorted Roux personnel on two site visits in July and August 2020, stated that a 50-gallon UST was removed from the site approximately 25 years earlier. Based on the relatively small size of the UST, it was removed without regulatory oversight. The project site owner stated no staining or odors were observed in the underlying soil once the UST was removed. Although the UST was small and no impacts were reportedly observed, the UST was removed without proper oversight and no soil samples were collected below the UST. Files provided by the CCCFPD did not reveal records associated with the project site or this UST. Although no indication of a release has been reported at the project site and the tank was relatively small, it is possible that releases from the gasoline UST could have historically occurred, which is considered a REC. 6 California Environmental Protection Agency (Cal/EPA).

One of the borings, RB-2, located at the approximate location of the former UST, was additionally advanced from 3 to 5 feet bgs using a direct push technology rig and converted into a temporary 5-foot soil vapor probe. Based on an elevated benzene concentration found in the soil vapor sample collected from RB-2, additional soil sampling took place on October 7, 2020, when four soil borings, RB-6 through RB-9, located around RB-2, were advanced to 5 feet bgs and converted into a 5-foot temporary soil vapor probes. Additionally, on December 15, 2020, Roux conducted groundwater sampling was conducted in the vicinity of boring RB-2. Concentrations detected in soil vapor samples (collected at the approximate location of the former UST) were compared to Regional Water Quality Control Board (RWQCB) February 2019 Residential Vapor Intrusion Environmental Screening Levels (ESLs). Based on the results of the additional investigation, benzene in soil vapor from all five soil vapor probes (RB-2 and RB-6 through RB-9) exceeded the RWQCB Residential ESL. However, these concentrations are relatively low and oxygen concentrations in soil vapor indicate that conditions in soil in the vicinity of RB-2 are favorable to the natural degradation of petroleum hydrocarbons. In addition, groundwater investigation confirmed that no benzene source exists in groundwater in the vicinity of RB-2. Benzene detection in the ground water sample was below the RWQCB Vapor Intrusion ESL. No other volatile organic compounds were detected in the grab groundwater sample. Based on the results of the additional investigation, benzene in soil vapor from all five soil vapor probes (RB-2 and RB-6 through RB-9) exceeded the RWQCB Residential ESL. However, the concentrations were relatively low and oxygen concentrations in soil vapor indicate that conditions in soil in the vicinity of RB-2 are favorable to the natural degradation of petroleum hydrocarbons. In addition, the groundwater investigation confirmed that no benzene source exists in groundwater in the vicinity of RB-2. However, soil aeration should be completed as mitigation to address the benzene detected in soil vapor. The project site was utilized for orchards between 1939 and the 1960s. Potential residual pesticide impacts in shallow soils is considered by Roux to be a BER. During the soil sampling discussed above, and to assess if shallow soil has been impacted by historical agricultural use, soil samples were collected from borings RB-1 through RB-5, located throughout the project site. Soil samples were taken at 1 and 3 feet bgs. Concentrations detected in soil were compared to the RWQCB February 2019 Residential Soil Direct Exposure ESLs as well as the San Francisco Bay Area natural background concentrations in soil, specifically for arsenic. The soil sampling results indicate that all detections, including pesticides, metals, total petroleum hydrocarbons (TPH), and volatile organic compounds (VOCs), were below the applicable Residential ESLs background levels, and arsenic concentrations were below natural background concentration. These results include samples collected from RB-2, RB-6, and RB-9 based on elevated photo ionization detector (PID) readings during logging. Three irrigation wells were observed at the project site. One of the wells is located in the former school courtyard in the southern portion of the project site, reportedly set at a depth of approximately 60 feet bgs, according to the project site owner. Accompanying the well is a filter and a pressure tank. The remaining two irrigation wells are located closer to the northern boundary of Contra Costa County–Oak Road Townhouse Condominiums Project Hazards and Hazardous Materials Draft EIR 3.8-6 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-08 Hazards.docx the project site behind the buildings at 2747 Oak Road and 2771 Oak Road, and are reportedly not active and the depths are unknown. The well behind 2771 Oak Road is uncovered. Roux identified these wells as a BER, stating that these wells would need to be properly decommissioned prior to redevelopment. A public records search of the DTSC indicated that the facility had an active listing in the Hazardous Waste Tracking System (HAZNET) in 2012. The project site owner was interviewed as part of the Phase I ESA and Limited Phase II Investigation and stated that he does not have information regarding this listing. Additional site observations identified in the Phase I ESA and Limited Phase II Investigation include the following: • No hazardous substances were observed on-site other than small containers of conventional cleaning supplies and insecticides. • Several transformers were observed outside the project site on utility poles along Oak Road; however, they appeared to be in good condition and are too high to pose a leaking risk to the soil or groundwater. • No staining or stressed vegetation was observed at the project site. • Several drains were located within bathroom spaces and outside in the paved courtyard area; however, no staining was observed around the drains. • Garbage collection services ceased at the project site around June 2020, following the closure of the Palmer School. • No wastewater processes were observed on the project site. Radon Radon is a carcinogenic, radioactive gas resulting from the natural breakdown of uranium in soil, rock, and water. Radon gas enters a building through cracks in foundations and walls. Once inside the building, radon decay products may become attached to dust particles and inhaled, or the decayed radioactive particles alone may be inhaled and cause damage to lung tissue. The EPA has established a safe radon exposure threshold of 4 picocuries per liter of air (pCi/l). The California Department of Public Health has conducted more than 48,000 indoor radon tests in more than 1,700 zip codes throughout the State.10 Table 3.8-1 summarizes indoor radon tests conducted in the four Walnut Creek zip codes. Approximately 7 percent of the indoor radon tests yielded results above 4 pCi/l. The California Department of Public Health classifies areas with 0 to 7 percent of samples exceeding 4 pCi/l to be areas of low radon potential. 10 California Department of Public Health. 2016.

Low Frequency Electromagnetic Fields Electrical transmission and distribution lines emit extremely low frequency electromagnetic fields (EMFs), which have been suspected to be linked to cancer. However, scientific research has never conclusively established a link between EMFs and cancer. In 2007, the World Health Organization (WHO) issued a report titled “Environmental Health Criteria 238, Extremely Low Frequency Fields”11 that concluded that evidence between extremely low frequency EMFs and childhood leukemia is not strong enough to be considered causal, although it did note that the issue still was of concern. The same report indicated that there is inadequate evidence or no evidence linking low frequency EMFs and health effects associated with all other diseases. A high voltage power line parallels the Iron Horse Trail approximately 800 feet east of the project site. 3.8.3 - Regulatory Framework Federal Occupational Health and Safety Act The Occupational Safety and Health Administration (OSHA) of the United States Department of Labor is responsible for implementing and enforcing federal laws and regulations that address worker health and safety. OSHA requires specific training for hazardous materials users and handlers, provision of information (procedures for personal safety, hazardous materials storage and handling, and emergency response) to employees who may be exposed to hazardous materials, and acquisition of Material Safety Data Sheets (MSDS) from materials manufacturers. MSDS describe the risks, as well as proper handling and procedures, related to hazardous materials. Employee training must include response and remediation procedures for hazardous material releases and exposures. Construction workers and operational employees at the project site would be subject to these requirements. 11 World Health Organization (WHO). 2007.

In California, these requirements are implemented by Cal/OSHA under California Code of Regulations Title 8 (see further discussion of California Code of Regulations Title 8 below). The removal and handling of ACM is governed primarily by EPA regulations under Code of Federal Regulations Title 40. The regulations require that the appropriate State agency be notified before any demolition, or before any renovations, of buildings that could contain asbestos or ACM above a specified threshold. Resource Conservation and Recovery Act and Comprehensive Environmental Response, Compensation, and Liability Act The EPA is responsible for implementing and enforcing federal laws and regulations pertaining to hazardous materials. The primary legislation includes the Resource Conservation and Recovery Act of 1976 (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended by the Superfund Amendments and Reauthorization Act (SARA) and the Emergency Planning and Community Right-to-Know Act (known as SARA Title III). RCRA and the 1984 RCRA amendments regulate the treatment, storage, and disposal of hazardous and non-hazardous wastes and mandate that hazardous wastes be tracked from the point of generation to their ultimate fate in the environment, including detailed tracking of hazardous materials during transport and permitting of hazardous material handling facilities. As permitted by RCRA, in 1992, the EPA approved California’s program called the Hazardous Waste Control Law (HWCL), administered by the DTSC, to regulate hazardous wastes in California, as discussed further below. The purpose of CERCLA is to identify and clean up chemically contaminated sites that pose a significant environmental health threat, and the Hazard Ranking System is used to determine whether a site should be placed on the National Priorities List for cleanup activities. SARA relates primarily to emergency management of accidental releases and requires annual reporting of continuous emissions and accidental releases of specified compounds that are compiled into a nationwide Toxics Release Inventory. Finally, SARA Title III requires formation of State and local emergency planning committees that are responsible for collecting material handling and transportation data for use as a basis for planning and provision of chemical inventory data to the community at large under the “right-to-know” provision of the law. Hazardous Materials Transportation Act Under the Hazardous Materials Transportation Act of 1975, the United States Department of Transportation (USDOT), Office of Hazardous Materials Safety regulates the transportation of hazardous materials on water, rail, highways, through air, or in pipelines, and enforces guidelines created to protect human health and the environment and reduce potential impacts by creating hazardous material packaging and transportation requirements. It also includes provisions for material classification, packaging, marking, labeling, placarding, and shipping documentation. The USDOT provides hazardous materials safety training programs and supervises activities involving hazardous materials. In addition, the USDOT develops and recommends regulations governing the multimodal transportation of hazardous materials.

The SPCC Plan must identify appropriate spill containment measures and equipment for diverting spills from sensitive areas and must discuss facility-specific requirements for the storage system, inspections, recordkeeping, security, and training. Clean Water Act The Clean Water Act (CWA) (Title 33 § 1251 et seq. of the United States Code [33 USC 1251, et seq.]) is the major federal legislation governing water quality. The CWA established the basic structure for regulating discharges of pollutants into waters of the United States (not including groundwater). The objective of the act is to “restore and maintain the chemical, physical, and biological integrity of the nation’s waters.”12 The CWA establishes the basic structure for regulating the discharge of pollutants into waters of the United States. Responsibility for administering the CWA resides with the State Water Board and nine RWQCBs; the San Francisco Bay RWQCB administers the CWA for western Contra Costa County. Section 404 of the CWA regulates temporary and permanent fill and disturbance of waters of the United States, including wetlands. The United States Army Corps of Engineers (USACE) requires that a permit be obtained if a project proposes to place fill in navigable waters and/or to alter waters of the United States below the ordinary high-water mark in non-tidal waters. Section 401 of the CWA requires compliance with State water quality standards for actions within State waters. Compliance with the water quality standards required under Section 401 is a condition for issuance of a Section 404 permit. Under Section 401 of the CWA, every applicant for a permit or license for any activity that may result in a discharge to a water body must obtain a State water quality certification from the RWQCB to demonstrate that the proposed activity would comply with State water quality standards. State California Hazardous Waste Control Law The HWCL is the primary hazardous waste statute in the State of California and implements RCRA as a “cradle-to-grave” waste management system for handling hazardous wastes in a manner that protects human health and the environment and reduces potential resulting impacts of hazardous waste. The law specifies that generators of hazardous waste have the primary duty to determine whether their waste is hazardous and to ensure proper management. The HWCL also establishes criteria for the reuse and recycling of hazardous waste used or reused as raw materials. The law exceeds federal requirements by mandating source reduction planning and a much broader requirement for permitting facilities that treat hazardous waste. It also regulates several types of waste and waste management activities that are not covered by federal law. 12 United States Environmental Protection Agency (EPA). 2018.

(2) Pose a substantial present or potential hazard to human health or the environment, due to factors including but not limited to carcinogenicity, acute toxicity, chronic toxicity, bioaccumulative properties, or persistence in the environment, when improperly treated, stored, transported, or disposed of or otherwise managed. These regulations establish criteria for identifying, packaging, and labeling hazardous wastes; prescribe management practices for hazardous wastes; establish permit requirements for hazardous waste treatment, storage, disposal, and transportation; and identify hazardous waste that commonly would be disposed of in landfills. Under both the RCRA and the HWCL, hazardous waste manifests must be retained by the generator for a minimum of 3 years. The generator must match copies of the manifests with copies of manifest receipts from the treatment, disposal, or recycling facility. In accordance with Chapter 6.11 of the California Health and Safety Code (HSC § 25404, et seq.), local regulatory agencies enforce many federal and State regulatory programs through the CUPA program, including: • Hazardous Materials Business Plans (HMBPs) (HSC § 25501, et seq.); • Uniform Fire Code requirements (Uniform Fire Code [UFC] § 80.103, as adopted by the State Fire Marshal under HSC § 13143.9); • Underground storage tanks (HSC § 25280, et seq.); • Aboveground storage tanks (HSC § 25270.5(c)); and • Hazardous waste generator requirements (HSC § 25100, et seq.). Contra Costa Health Services Hazardous Materials Division is the CUPA for the County. As the CUPA, they enforce State statutes and regulations through the Hazardous Materials Unified Program Agency, which oversees aboveground petroleum tanks; generation of hazardous materials; storage and treatment; USTs; generation of medical waste; the accidental release prevention program; and Local Oversight Program. If a facility ever handles any individual hazardous material in an aggregate amount equal to or greater than 55 gallons (liquids), 500 pounds (solids), or 200 cubic feet (gases), an HMBP must be submitted. An HMBP must include: 13 FindLaw. 2020. California Code, Health and Safety Code - HSC § 25141. Website: https://codes.findlaw.com/ca/health-and-safety- code/hsc-sect-25141.html.

California Code of Regulations, Title 8 Cal/OSHA assumes primary responsibility for developing and enforcing workplace safety regulations. These regulations concern the use of hazardous materials in the workplace, including requirements for employee safety training; availability of safety equipment; accident and illness prevention programs; hazardous substance exposure warnings; and preparation of emergency action and fire prevention plans. Cal/OSHA also enforces hazard communication program regulations, including procedures for identifying and labeling hazardous substances, and requires that MSDS be available for employee information and training programs. Cal/OSHA standards are generally more stringent than federal regulations. Construction workers and operational employees at the project site would be subject to these requirements. California Code of Regulations, Title 8, Section 1529 authorizes Cal/OSHA to implement the survey requirements of Code of Federal Regulations Title 29 relating to asbestos. These federal and State regulations require facilities to take all necessary precautions to protect employees and the public from exposure to asbestos. Workers who conduct asbestos abatement must be trained in accordance with federal and State OSHA requirements. The Bay Area Air Quality Management District (BAAQMD) oversees the removal of regulated ACMs (see “Asbestos Demolition, Renovation, and Manufacturing Rule” below). California Code of Regulations Title 8, Section 1532.1 includes requirements to manage and control exposure to LBP. These regulations cover the demolition, removal, cleanup, transportation, storage, and disposal of lead-containing material. The regulations outline the permissible exposure limit, protective measures, monitoring, and compliance to ensure the safety of construction workers exposed to lead-based material. Loose and peeling LBP must be disposed of as a State and/or federal hazardous waste if the concentration of lead equals or exceeds applicable hazardous waste thresholds. Federal and State OSHA regulations require a supervisor who is certified in identifying existing and predictable lead hazards to oversee air monitoring and other protective measures during demolition activities in areas where LBP may be present. Special protective measures and notification of Cal/OSHA are required for highly hazardous construction tasks related to lead, such as manual demolition, abrasive blasting, welding, cutting, or torch burning of structures, where LBP is present.

California Code of Regulations, Title 22, Chapter 11, Article 3, “Soluble Threshold Limits Concentrations/Total Threshold Limits Concentration Regulatory Limits,” identifies the concentrations at which soil is determined to be a California hazardous waste. California’s Universal Waste Rule (22 CCR § 66273) provides an alternative set of management standards in lieu of regulation as hazardous wastes for certain common hazardous wastes, as defined in California Code of Regulations, Title 22, Section 66261.9. Universal wastes include fluorescent lamps, mercury thermostats, and other mercury-containing equipment. Existing structures may contain fluorescent light ballasts that could contain mercury or lead. The Alternative Management Standards for Treated Wood Waste (22 CCR § 67386) were developed by the DTSC to allow for disposal of treated wood as a non-hazardous waste, to simplify and facilitate the safe and economic disposal of such waste. Chemically treated wood can contain elevated levels of hazardous chemicals (e.g., arsenic, chromium, copper, pentachlorophenol, or creosote) that equal or exceed applicable hazardous waste thresholds. The Alternative Management Standards provide for less stringent storage requirements and extended accumulation periods, allow shipments without a hazardous waste manifest and a hazardous waste hauler, and allow disposal at specific non-hazardous waste landfills. Porter-Cologne Water Quality Control Act The Porter-Cologne Water Quality Control Act of 1969 (Porter-Cologne Act) is California’s statutory authority for the protection of water quality. Under the Porter-Cologne Act, the State must adopt water quality policies, plans, and objectives that protect the State’s waters for the use and enjoyment of the people. Regional authority for planning, permitting, and enforcement is delegated to the nine RWQCBs. The RWQCBs are required to formulate and adopt water quality control plans (also known as basin plans) for all areas of the region and establish water quality objectives in the plans. The Porter-Cologne Act sets forth the obligations of State Water Board and RWQCBs to adopt and periodically update water quality control plans that recognize and reflect the differences in existing water quality, the beneficial uses of the region’s groundwater and surface water, and local water quality conditions and problems. It also authorizes the State Water Board and RWQCBs to issue and enforce waste discharge requirements and to implement programs for controlling pollution in State waters. Finally, the Porter-Cologne Act also authorizes the State Water Board and RWQCBs to oversee site investigation and cleanup for unauthorized releases of pollutants to soils and groundwater and in some cases to surface waters or sediments. California Emergency Response Plan California has developed an emergency response plan to coordinate emergency services provided by federal, State, and local governments and private agencies. Responding to hazardous materials incidents is one part of this plan. The plan is administered by the California Governor’s Office of Emergency Services, which coordinates the responses of other agencies. The Contra Costa County Office of the Sheriff’s Emergency Services Division coordinates response to emergencies in unincorporated areas of the County. Emergency response team members respond and work with local fire and police agencies, emergency medical providers, the California Highway Patrol, California Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Hazards and Hazardous Materials FirstCarbon Solutions 3.8-13 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-08 Hazards.docx Department of Forestry and Fire Protection (CAL FIRE), the California Department of Fish and Wildlife (CDFW), and the California Department of Transportation (Caltrans). California Department of Forestry and Fire Protection CAL FIRE has mapped fire threat potential throughout California. CAL FIRE maps fire threat based on the availability of fuel and the likelihood of an area burning (based on topography, fire history, and climate). The threat levels include no fire threat, moderate, high, and very high fire threat. Further, the maps designate the County as the Local Responsibility Area (LRA) for the project site. Additionally, CAL FIRE produced a 2010 Strategic Fire Plan for California, which contains goals, objectives, and policies to prepare for and mitigate the effects of fire on California’s natural and built environments. CAL FIRE’s Office of the State Fire Marshal provides oversight of enforcement of the California Fire Code as well as overseeing hazardous liquid pipeline safety. California Building Standards Code The State of California provided a minimum standard for building design through the 2019 California Building Standards Code (CBC), which is located in Part 2 of Title 24 of the California Code of Regulations. The 2019 CBC is based on the 2018 International Building Code, but has been modified for California conditions. It is generally adopted on a jurisdiction-by-jurisdiction basis, subject to further modification based on local conditions. Commercial and residential buildings are plan- checked by local City and County building officials for compliance with the CBC. Typical fire safety requirements of the CBC include the installation of sprinklers in all new high-rise buildings and residential buildings; the establishment of fire resistance standards for fire doors, building material; and specific types of construction. California Public Resources Code The California Public Resources Code includes fire safety regulations that restrict the use of equipment that may produce a spark, flame, or fire; require the use of spark arrestors on construction equipment that use an internal combustion engine; 14 specify requirements for the safe use of gasoline-powered tools in fire hazard areas; and specify fire suppression equipment that must be provided on-site for various types of work in fire-prone areas. These regulations include the following: • Earthmoving and portable equipment with internal combustion engines shall be equipped with a spark arrestor to reduce the potential for igniting a wildland fire (Public Resources Code [PRC] § 4442). • Appropriate fire suppression equipment shall be maintained during the highest fire danger period—from April 1 to December 1 (PRC § 4428). • On days when a burning permit is required, flammable materials shall be removed to a distance of 10 feet from any equipment that could produce a spark, fire, or flame, and the construction contractor shall maintain the appropriate fire suppression equipment (PRC § 4427). 14 A spark arrestor is a device that prohibits exhaust gases from an internal combustion engine from passing through the impeller blades where they could cause a spark. A carbon trap is commonly used to retain carbon particles from the exhaust.

Regional BAAQMD Asbestos Demolition, Renovation, and Manufacturing Rule The removal of building ACMs is subject to the limitations of BAAQMD Regulation 11, Rule 2, “Hazardous Materials; Asbestos Demolition, Renovation, and Manufacturing.” This rule prohibits visible emissions to outside air from any operation involving the demolition of any structure containing asbestos, and sets out requirements for demolition of such structures, including a pre- demolition survey conducted by a certified professional. All friable (i.e., crushable by hand) or non- friable ACMs that may be damaged must be abated before demolition in accordance with applicable requirements. Friable ACMs must be disposed of as asbestos waste at an approved facility. Non- friable ACMs may be disposed of as non-hazardous waste at landfills that accept such wastes. Association of Bay Area Governments Hazard Mitigation Plan The Association of Bay Area Governments (ABAG) multi-jurisdictional Local Hazard Mitigation Plan for the San Francisco Bay Area was updated in 2010 in partnership with the Bay Conservation and Development Commission. Adapting to Rising Tides Program to support local governments in the regional plan for existing and future hazards of climate change. This detailed 5-year plan identifies potential natural and human-made hazards, assesses their potential risks, and includes mitigation methods to reduce risks. The potential hazards identified in the plan include earthquakes and liquefaction, wildfires, floods, drought, solar storms, dam or levee failure, disease outbreak, freezes, wind, heat, thunder and lightning storms, siltation, tornadoes, hazardous materials, slope failure and mudflows, and other hazards. Similarly, mitigation measures include hazard event planning, emergency preparedness coordination, education, facility upgrades, and monitoring actions. Local Contra Costa County Hazard Mitigation Plan Contra Costa County and a partnership of local governments within the County have developed a Hazard Mitigation Plan (HMP) to reduce future losses resulting from disasters. Hazard mitigation is the use of long- and short-term strategies to reduce the loss of life, personal injury, and property damage that can result from a disaster. It involves planning efforts, policy changes, programs, capital projects, and other activities that can mitigate the impacts of hazards. The HMP contains the following goals aimed at reducing the vulnerability from natural hazards within the County in a cost- effective manner: Goal 1 Save, or protect lives and reduce injury. Goal 2 Increase resilience of infrastructure and critical facilities. Goal 3 Avoid, minimize, or reduce damage to property.

Goal 5 Build and support capacity to enable local government and the public to prepare, respond, and recover from the impact of natural hazards. Contra Costa County Emergency Operations Plan The Contra Costa County Operational Area Emergency Operations Plan (EOP) addresses response to emergency incidents affecting the County. The Contra Costa Operational Area consists of the cities/towns, special districts, reclamation districts, municipal improvement districts and the unincorporated areas within the County. The EOP is based on the functions and principles of the California Standardized Emergency Management System, the National Incident Management System, and the Incident Command System. It identifies how the County emergency operational system fits into the overall California and national risk-based, all-hazard emergency response and recovery operations plans. Contra Costa County General Plan The General Plan establishes the following goals, policies, and implementation measures related to hazards and hazardous materials relevant to this analysis: Hazardous Materials Uses Goal 10-I To provide public protection from hazards associated with the use, transport, treatment, and disposal of hazardous substances. Goal 10-N To provide for a continuing high level of public protection services and coordination of services in a disaster. Policies Policy 10-62 Storage of hazardous materials and wastes shall be strictly regulated. Policy 10-68 When an emergency occurs in the transportation of hazardous materials, the County Office of Emergency Services shall be notified as soon as possible.

Policy 10-86 In order to ensure prompt public protection services, dwelling unit numbers shall be required to be easily seen from the street or road. Contra Costa County Ordinance Code Division 450, Hazardous Materials and Wastes, of the Ordinance Code provides regulations regarding hazardous material response plans, inventories, underground storage, and risk management. In part, this Ordinance Code requires that any business that handles a specific quantity of hazardous materials establish a HMBP for emergency response to a release or threatened release of a hazardous material. 3.8.4 - Impacts and Mitigation Measures Significance Criteria According to the California Environmental Quality Act (CEQA) Guidelines Appendix G Environmental Checklist, to determine whether impacts related to hazards and hazardous materials have significant environmental effects, the following questions are analyzed and evaluated. Would the proposed project: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Contra Costa County–Oak Road Townhouse Condominiums Project Hazards and Hazardous Materials Draft EIR 3.8-18 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-08 Hazards.docx d) Be located on a site which is included on a list of hazardous materials sites compiled under Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard or excessive noise for people residing or working the project area? f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? g) Expose people or structures, either directly or indirectly to a significant risk of loss, injury, or death involving wildland fires? Approach to Analysis This evaluation focuses on whether the proposed project would result in changes to the physical environment that would cause or exacerbate adverse effects related to the use, transportation, disposal, accidental release, or emission of hazardous materials. The evaluation also includes a determination of whether the proposed project would result in changes to the physical environment, or would impair or interfere with emergency response plans, or would expose people or structures to increased wildfire hazards or dangers from overhead power lines. For the evaluation of potential construction-related and operational impacts from existing hazardous materials in project site soils, sediments, groundwater, surface water, and structures, the results of environmental sampling are compared to identified screening levels. The following analysis is based, in part, on information provided by the General Plan and the Phase I ESA prepared for the proposed project. Additional analyses regarding hazards and health risk related to emissions of toxic air contaminants (TACs) are addressed in Section 3.2, Air Quality. Flooding and inundation hazards, including those related to erosion and mudflow, are addressed in Section 3.9, Hydrology and Water Quality. Transportation-related safety hazards are addressed in Section 3.14, Transportation. Other geotechnical-related safety hazards, such as earthquakes, are addressed in Section 3.6, Geology and Soils. Finally, excessive noise exposure with respect to airport use or air traffic is addressed in Section 3.11, Noise. Specific Thresholds of Significance For purposes of this analysis, the following thresholds are used to evaluate the significance of hazards and hazardous materials impacts resulting from implementation of the proposed project. • Routine transport, use, and/or disposal of hazardous materials. • Regular transport of hazardous materials to/from the project site on an unsuitable road or use of highly volatile hazardous materials. • Location within 0.25-mile of an existing or proposed school in conjunction with hazardous emissions or handle hazardous materials, waste, or substances. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Hazards and Hazardous Materials FirstCarbon Solutions 3.8-19 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-08 Hazards.docx • Listing on hazardous materials site list and distance of project site to listed hazardous material sites. These lists include the following: - The California Environmental Protection Agency (Cal/EPA) - California Facility Inventory Database (CA FID) UST and State Water Efficiency and Enhancement Program (SWEEP) - Hazardous Waste Tracking System - DTSC EnviroStor and BAAQMD - State Water Board GeoTracker regulated facilities databases for files related to possible RECs • Location proximate to an airport and reduction of safety of people working or residing in the area. • Impairing implementation of or interference with an adopted emergency response plan or emergency evacuation plan via blockage of an evacuation route or provision of only one access point for emergency vehicles. • Placement of structures in a designated wildland fire urban interface zone or proximate to unmanaged open space area that is susceptible to wildfires. Impact Evaluation Routine Transport, Use, or Disposal of Hazardous Materials Impact HAZ-1: The proposed project could create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials. Construction During construction, both within the project site and within the areas proposed for the off-site improvements, the proposed project would be expected to involve the transport, use, and disposal of hazardous materials, such as diesel fuels, aerosols, and paints. The proposed project would be subject to the Hazardous Materials Transportation Act, California Public Resources Code, and other State and local regulations that would reduce and limit the associated risks. Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations, including the EPA, RCRA, Caltrans, and HMP. During project site preparation, all existing structures, pavement, and landscaping would be demolished. Given the age of the existing structures on the project site, it is conceivable that ACM and LBP may exist within these structures, and their removal could potentially create a significant hazard to construction workers. This represents a potentially significant impact. However, implementation of Mitigation Measure (MM) HAZ-1a, which requires the applicant to conduct asbestos and lead paint surveys prior to demolition activities and to safely remove and dispose of any such materials in accordance with State standards, would ensure impacts are reduced to a less than significant level. Contra Costa County–Oak Road Townhouse Condominiums Project Hazards and Hazardous Materials Draft EIR 3.8-20 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-08 Hazards.docx As described in the Phase I ESA and Limited Phase II Investigation, no hazardous materials other than small containers of conventional cleaning supplies and insecticides were observed at the project site. With implementation of HAZ-1b, which would require proper removal and disposal of these existing materials, impacts related to these potential hazards would be less than significant. As described in the Phase I ESA and Limited Phase II Investigation, three irrigation wells were observed on-site: One at a depth of approximately 60 feet bgs and accompanied by a filter and a pressure tank, and two of unknown depths. In addition, one of these wells was observed to be uncovered. Should these groundwater irrigation wells be encountered during ground-disturbing activities, construction workers could potentially be exposed to a significant hazard. This represents a potentially significant impact. Therefore, MM HAZ-1c would be implemented, which requires proper closure of the three irrigation wells in accordance with local, State, and federal regulations. With implementation of MM HAZ-1c, impacts related to the irrigation wells would be less than significant. As described in the Phase I ESA and Limited Phase II Investigation, a 50-gallon UST was removed from the site approximately 25 years ago without regulatory oversight. Although no indication of a release has been reported and the tank was relatively small, it is possible that releases from the gasoline UST could have historically occurred, which is considered a REC. Benzene concentrations in soil vapor from all five soil vapor probes in the vicinity of the former UST (RB-2 and RB-6 through RB- 9) exceeded the RWQCB Residential ESL. While concentrations were relatively low and oxygen concentrations in soil vapor indicate that conditions in soil in the vicinity of RB-2 are favorable to the natural degradation of petroleum hydrocarbons, this represents a potentially significant impact for construction workers. With implementation of HAZ-1d, which would require soil aeration, impacts related to these potential hazards would be less than significant. With implementation of MM HAZ-1a, MM HAZ-1b, MM HAZ-1c, and MM HAZ-1d, construction- related impacts associated with hazardous materials on the project site would be considered less than significant. Operation During project operations, hazardous materials may be handled on the project site. Because of the nature of the project, hazardous materials used on-site may vary but would likely be limited to small quantities of fertilizers, herbicides, pesticides, solvents, cleaning agents, and similar materials used for daily residential operations and maintenance activities. These types of materials are common for residential developments such as the project and represent a low risk to people and the environment when used as intended. Further, compliance with applicable plans and regulations, including the Contra Costa County General Plan (General Plan) policies, would provide public protection from hazards associated with the use, transport, treatment, and disposal of hazardous substances. Therefore, operational impacts related to public hazard risk as a result of hazardous materials transport, use, or disposal would be less than significant. Level of Significance Before Mitigation Potentially significant impact.

These surveys shall be conducted prior to the disturbance or removal of any suspect asbestos-containing materials (ACM) and lead-based paint (LBP), and these materials shall be characterized for asbestos and lead by a reliable method. All activities involving ACM and LBP shall be conducted in accordance with governmental regulations, and all removal shall be conducted by properly licensed abatement contractors. MM HAZ-1b Proper Disposal of Hazardous Materials Such As Cleaning Supplies and Insecticides Prior to the issuance of a grading permit, the applicant shall remove and dispose of all materials observed during the site reconnaissance for the Phase I Environmental Site Assessment (Phase I ESA) in accordance with applicable local, State, and federal regulations. The materials include, but are not limited to containers of cleaning supplies and insecticides. MM HAZ-1c Closure of On-site Irrigation Wells Prior to the issuance of a grading permit, the three on-site irrigation wells shall be properly closed under permit in accordance with applicable local, State, and federal regulations. MM HAZ-1d Soil Aeration The applicant shall complete the soil aeration and soil vapor testing during demolition and rough grading operations. Once the soil aeration is completed which consists of spreading excavated soil on the ground in an approximately 18-inch-thick layer, mixing of the soil (tilling) shall be performed regularly to maintain aerobic conditions (presence of oxygen). The soil shall be thoroughly tilled using equipment such as a Terex RS600 Reclaimer/Stabilizer. An Environmental Health Licensed Professional shall spot check to ensure that the process is implemented. A total of six tilling passes shall be performed through the proposed excavation area (approximately 30 feet long by 20 feet wide and 6 feet deep with a total volume of 135 cubic yards). During the tilling operation, air quality monitoring shall be performed with a photo ionization detector (PID) 3 inches above the soils and also in the breathing zone. Dust control measures shall be implemented during the aeration process (as spelled out in MM AIR-2), and dust monitoring shall be performed in the perimeter of the project site.

If the soil vapor sampling finds no benzene Environmental Screening Level (ESL) exceedances, then the applicant shall have the Phase I Environmental Site Assessment and Phase II Environmental Investigation Report prepared by Roux Associates, Inc. (Roux) in August 2021, updated memorializing the implementation of the mitigation and confirming that no Recognized Environmental Conditions (REC) exist on the site and provide a copy to the Department of Conservation and Development, Community Development Division demonstrating that benzene levels no longer exceed the ESL. If soil vapor exceedances are identified after soil excavation and aeration, then a Soil Management Plan (SMP) shall be prepared and forwarded to an appropriate environmental oversight agency for disposition. A copy of the SMP will also be provided to the Department of Conservation and Development, Community Development Division. All construction work shall cease in the area of the underground storage tank (UST) as shown in the Roux report, including the aeration area, until the disposition of the SMP is determined by the environmental oversight agency. Once the issue has been addressed to the satisfaction of the environmental oversight agency, evidence shall be provided to the satisfaction of the Department of Conservation and Development, Community Development Division and construction activities may resume on the former UST area. Level of Significance After Mitigation Less than significant impact. Hazardous Materials Upset Risk Impact HAZ-2: The proposed project would not create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials into the environment. Construction Construction activity, both within the project site and within the areas proposed for the off-site improvements, would be expected to involve the transport, use, and disposal of hazardous materials, such as diesel fuels, aerosols, and paints. The use of these materials would be subject to the Hazardous Materials Transportation Act, California Public Resources Code, and other State and local regulations that would limit the use of hazardous materials and reduce the associated risks of exposure. Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations, including the EPA, RCRA, Caltrans, the Hazardous Materials Transportation Act, and the Contra Costa County HMP. Therefore, construction impacts related to hazardous materials upset risk would be less than significant.

As such, the proposed project would not be expected to include industrial or retail development that involves hazardous materials such as gas stations, paint stores, or auto parts stores. Unlike industrial or retail facilities, residential development does not involve the type or quantity of hazardous materials that could pose a significant environmental accident. Small quantities of hazardous materials would be used on-site during operation of the project, but not in sufficient quantities to create significant hazard in the unlikely event of upset or accident. These types of materials are common in such residential projects and represent a low risk to people and the environment when used as intended, and would not be expected to result in the release of hazardous materials into the environment. As such, operational impacts related to hazardous materials upset risk would be less than significant. Level of Significance Less than significant impact. Hazardous Emissions Proximate to a School Impact HAZ-3: The proposed project would not emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school. Construction The project site, including the areas proposed for off-site improvements, are not located within 0.25- mile of an existing or proposed school. The closest school, Fusion Academy (a private school), is located approximately 0.33 mile to the north. Construction activity would be expected to involve the transport, use, and disposal of hazardous materials, such as diesel fuels, aerosols, and paints. The handling, transport, use, and disposal of hazardous materials must comply with the Hazardous Materials Transportation Act, California Public Resources Code, and other State and local regulations, which further limits the risk of emissions. As such, the proposed project would not emit hazardous emissions or handle hazardous materials within 0.25 mile of a school. Therefore, construction impacts related to hazardous emissions proximate to a school would be less than significant. Operation The project site is not located within 0.25 mile of a school. In addition, the proposed project would not be expected to include industrial or retail development that involves hazardous materials such as gas stations, paint stores, or auto parts stores. Unlike industrial or retail facilities, residential development does not involve the type or quantity of hazardous materials that could pose a significant environmental accident. Therefore, operational impacts related to hazardous emissions proximate to a school would be less than significant. Level of Significance Less than significant impact.

Construction Impacts related to locating a project on a hazardous materials site per Government Code Section 65962.5 are limited to operational impacts. No respective construction impacts would occur. Operation Roux conducted regulatory records review of DTSC EnviroStor; RWQCB, including Geotracker and Stormwater Multiple Application and Report Tracking System (SMARTS); California Department of Oil, Gas, and Geothermal Resources (DOGGR) for files related to possible RECs was conducted for the project site. in addition, Roux also submitted public record requests to relevant regulatory agencies, including DTSC EnviroStor and HWTS, RWQCB Geotracker and SMARTS, BAAQMD, the City of Walnut Creek, CCCFPD, Contra Costa Health Services Hazardous Materials Program, and Contra Costa County Department of Conservation and Development. The results are compiled in the Phase I ESA and Limited Phase II Investigation included as Appendix F. As described in the Phase I ESA and Limited Phase II Investigation, benzene concentrations in soil vapor from five soil vapor probes in the vicinity of the former 50-gallon UST exceeded the RWQCB Residential ESL. While concentrations were relatively low and oxygen concentrations in soil vapor indicate that conditions in soil in the vicinity of the approximate location of the former UST are favorable to the natural degradation of petroleum hydrocarbons, this represents a potentially significant impact for construction workers. With implementation of MM HAZ-1d, which would require soil aeration, impacts related to these potential hazards would be less than significant. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures Implement MM HAZ-1d. Level of Significance After Mitigation Less than significant impact. Proximity to Public Airport Safety Hazard Impact HAZ-5: The proposed project would not be located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, and result in a safety hazard or excessive noise for people residing or working the project area. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Hazards and Hazardous Materials FirstCarbon Solutions 3.8-25 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-08 Hazards.docx Construction Impacts related to exposure of people to safety hazards or excessive noise in proximity to an airport are limited to operational impacts. No respective construction impacts would occur. Operation As part of operation, the project would not be located within an airport land use plan or within 2 miles of a public airport. The closest public airport, Buchanan Field, is located approximately 4.4 miles to the north of the project site. At this distance, the project is not located within an airport land use plan or within 2 miles of a public airport. Therefore, no impact related to exposure of people to safety hazards or excessive noise in proximity to an airport would occur. Level of Significance No impact. Emergency Response and Evacuation Impact HAZ-6: The proposed project would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan. Construction During construction, it is expected that construction equipment and vehicles would be accessing and leaving the project site, which in turn could potentially impede evacuation or emergency vehicle access. However, as discussed under Impact TRANS-5 in Section 3.14, Transportation, the proposed project would result in less than significant impacts related to emergency vehicle access. In addition, the proposed project would comply with the Contra Costa County Emergency Plan, ensuring efficient response to emergency incidents associated with emergencies affecting Contra Costa County. Therefore, construction impacts related to emergency response and evacuation would be less than significant. Operation The Contra Costa County Operational Area EOP outlines general procedures in response to emergency crises, such as evacuations. Included in this Plan is information regarding evacuations and shelter-in-place orders as well as who has the authority to issue these orders. The main arterial roads into and out of the project vicinity are Jones Road and Oak Road, which would serve as the main emergency response and evacuation routes into and out of the project vicinity. With adherence to the procedures of the Contra Costa County Operational Area EOP, the project would not conflict with the Contra Costa County Operational Area EOP or General Plan safety policies. As indicated in Section 3.12, Population and Housing. the proposed project would not create a permanent increase in population unaccounted for in the General Plan that could lead to overwhelming call for police and fire services. In addition, the project site would be designed in accordance with the County’s standards to accommodate emergency vehicle access by providing two points of access that would be available to emergency vehicles. Therefore, operational impacts related to emergency response and evacuation would be less than significant.

Wildland Fires Impact HAZ-7: The proposed project would not expose people or structures, either directly or indirectly to a significant risk of loss, injury or death involving wildland fires. Construction Impacts related to wildland fire hazard risks are limited to operational impacts. No respective construction impacts would occur. Operation As indicated by the General Plan, fire hazards present a considerable problem throughout the County, primarily within undeveloped areas with natural vegetation and steep slopes. The project site is located in a County island and is surrounded to the east, west, and south by the City of Walnut Creek, to the northeast by the City of Concord, and to the northwest by the City of Pleasant Hill. It is relatively flat in elevation (approximately 90 to 95 feet above mean sea level). The project site is mostly surrounded by urbanized uses on areas relatively flat in elevation, lacking in woodlands or vegetation that could provide fuel load for wildfire, or steep slopes that could cause fire to spread more rapidly. The project site is surrounded by other features that provide fuel breaks in the event of a fire, such as Oak Road and Jones Road. In addition, the Contra Costa Canal is approximately 450 to 650 feet south of the project site. According to CAL FIRE, the project site is not located in a Moderate, High, or Very High Fire Hazard State Responsibility Area.15 Two miles west of the project site (Briones Regional Park) is designated as a High Fire Hazard Severity Zone.16 The BAAQMD monitors the Bay Area’s air quality at a number of stations, and the closest station to the project site is located in the City of Concord, approximately 4 miles to the northeast. The average wind speed at this station varied from month to month and ranged from 7–16 mph in 2020.17 Given that the project site is not located on or near steep terrain surrounded by natural vegetation, is surrounded by urban uses, and does not consistently experience high winds, the project site would not be prone to wildfires. Compliance with applicable State and local plans and regulations would decrease the risk of impacts related to wildland fire hazards. Specifically, the General Plan policies incorporate requirements for fire-safe construction into the land use planning and approval process and ensure special fire protection for high-risk land uses and structures. Contra Costa County also implements the Contra Costa County Operational Area EOP, which addresses the response to emergency incidents associated with emergencies affecting Contra Costa County. Furthermore, as indicated in Section 3.13, Public Services and Recreation, the proposed project would be adequately served in terms of 15 California Department of Forestry and Fire Protection (CAL FIRE). 2007 Contra Costa County Fire Hazard Severity Zone in State Responsibility Area.

Finally, proposed structures would be required to comply with the California Fire Code with regard to emergency access and types of building materials. Therefore, impacts related to wildland fire risk would be less than significant. Level of Significance Less than significant impact. 3.8.5 - Cumulative Impacts The geographic scope of the cumulative analysis related to hazards and hazardous materials is the project vicinity or roughly the western portion of the County. The analysis also considers the foreseeable development projects listed in Table 3-1 (See Chapter 3, Environmental Impact Analysis) in unincorporated Contra Costa County and the surrounding cities, in addition to the proposed project. Hazardous Materials Exposure Risk In general, exposure to hazardous materials may cause localized adverse effects. A combination of federal, State, and local regulations limit or minimize the potential for exposure to hazardous materials. Development listed in Table 3-1 primarily consists of residential and commercial development. The types and sizes of development anticipated in the project area would not involve large quantities of hazardous materials or activities that transport or handle hazardous materials. Cumulative projects would be subject to the Hazardous Materials Transportation Act, California Public Resources Code, and other State and local regulations that would reduce and limit the associated risks. Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations, including the EPA, RCRA, Caltrans, and HMP. However, cumulative projects listed in Table 3-1 may include demolition of existing structures that have the potential to contain hazardous building materials. Building materials may contain ACM and LBP. To address potential release of hazardous materials, the County would assess structures and impose standard mitigation (required testing, removal, and proper disposal) to minimize release prior to any demolition. Additionally, regional, State, and federal regulations would apply to countywide development, and, for these reasons cumulative projects, would result in a less than significant cumulative impact related to exposure to hazardous materials. Moreover, the proposed project’s incremental contribution would not be significant. To reduce the proposed project’s impacts to below a level of significance and ensure a less than significant contribution to cumulative impacts, the proposed project would implement MM HAZ-1a through MM HAZ-1c, and comply with all applicable policies related to transport, use, and disposal of hazardous materials, as discussed above. Hazards and Emergency Response The main arterial streets that would serve as the most likely evacuation routes out of the central portion of the County include I-680, SR-24, and Ygnacio Valley Road. Planned uses as proposed by the cumulative projects are contemplated in the General Plan, would result in predominantly in-fill development, and would not significantly increase need for emergency services, including those Contra Costa County–Oak Road Townhouse Condominiums Project Hazards and Hazardous Materials Draft EIR 3.8-28 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-08 Hazards.docx related to wildfires. Furthermore, all construction would adhere to the regulations included in the California Fire Code that are designed to minimize the potential for the release of hazardous materials or uncontrolled fires. Once development is proposed, the County would assess the needs for fire protection services and inform efforts to improve or expand needed facilities. As listed in Table 3-1, cumulative development in the County primarily consists of residential and commercial development. New residential developments would contribute to increases in the County’s population. All development would, however, comply with emergency access requirements as projects condition. Furthermore, cumulative development in County, including the proposed project, would not result in permanent road closures, nor impede established emergency access routes, nor interfere with emergency response requirements. As such, there would be a less than significant cumulative impact associated with hazards and emergency response. Moreover, as discussed above, the proposed project would fully comply with all applicable regulations and, therefore, its contribution would not be cumulatively considerable. Level of Cumulative Significance Less than significant impact.

Descriptions and analysis in this section are based on the Contra Costa County General Plan (General Plan) and the site-specific documents prepared in 2021 by Ruggeri-Jensen-Azar: Preliminary Hydrology and Hydraulics Calculations prepared in January 2021 and updated in March 2021 1 and Preliminary Stormwater Control Plans prepared in January 2021 and updated in March 2021.2 The updated documents are included in Appendix G. No comments were received during the Notice of Preparation (NOP) comment period related to hydrology and water quality. 3.9.2 - Environmental Setting Surface Hydrology Walnut Creek Watershed The Contra Costa Clean Water Program (CCCWP) designates watersheds in the County. According to the CCCWP, the project site is located within the Walnut Creek Watershed, which encompass 93,556 acres in central Contra Costa County. Draining the west side of Mount Diablo and the east side of the East Bay Hills, its major tributaries include San Ramon Creek, Bollinger Creek, Las Trampas Creeks, Pine Creek, and Galindo Creek. These tributaries constitute important watersheds draining into the Walnut Creek, and together the form the Walnut Creek Watershed.3 Project Site The project site does not contain any creeks or bodies of water. The closest creek to the project site is Walnut Creek, located approximately 1750 feet to the south. The Contra Costa Canal is approximately 450-600 feet to the south. The project site is at elevations ranging from approximately 90 to 95 feet above mean sea level.

Groundwater Basin Hydrology Contra Costa County Area The Contra Costa Water District Draft 2020 Urban Water Management Plan (UWMP) identified the Ygnacio Valley, Clayton Valley, Pittsburg Plain, and East Contra Costa Groundwater Basins as the primary groundwater basins within its service area.4 The Ygnacio Valley Groundwater Basin is located in northern Contra Costa County along the south shore of Suisun Bay. The basin surface area is approximately 15,900 acres bounded by Suisan Bay to the North, Interstate 680 (I-680) to the west, by the Concord Fault to the east, and by the City of Walnut Creek to the south.5 The Ygnacio Valley Groundwater Basin underlies the City of Pleasant Hill and City of Walnut Creek. The Ygnacio Valley Basin occupies a structural depression between the Berkeley Hills and the Diablo Range. Thick alluvial deposits that cover a faulted and folded complex of consolidate Cretaceous and Tertiary rocks underlie the basin. The water-bearing units in the basin are Quaternary alluvium and alluvial valley fill deposits. Aquifers in the basin area are hydrologically connected to the Sacramento River.6 Project Site The project site is located on the southern edge of the Ygnacio Valley Groundwater Basin.7 Three irrigation wells are located on the project site. Groundwater Water Quality Contra Costa County Area According to the California Department of Water Resources (DWR) Bulletin 118: Ygnacio Valley Groundwater Basin, no published groundwater quality data is available for the Basin.8 Project Site The project site is located within the Ygnacio Valley Groundwater Basin and is under the jurisdiction of the San Francisco Bay RWQCB. 4 Contra Costa Water District. 2021 Draft 2020 Urban Water Management Plan.

The County is a permittee under the Phase II NPDES Municipal Stormwater Permit, and implements the County-specific components of the CCCWP. The Contra Costa County Flood Control District (Flood Control District) guides regional drainage plans throughout the County. The Flood Control District owns property throughout the County for the purpose of constructing and maintaining regional flood control basins, channels, and creeks.9 Project Site The project site is generally flat with a gentle slope of approximately 5 percent in the northeasterly direction toward Oak Road, northwesterly toward Jones Road and with a localized portion of the site at the southwesterly portion of the site drains toward Jones Road as well. Currently, the on-site drainage and storm runoff generally sheet flows across the site or captured by on-site small drainage inlets connected by underground storm drain pipes and discharged into the existing storm drain facilities in Jones Road or Oak Road. Based on field observation and record drawings, it appears majority of the existing on-site drainage is discharged or conveyed via underground storm drains to the existing 30- inch storm drains in Oak Road. The project site is located within the County Flood Control Drainage Area 44B.10 Flooding and Inundation Contra Costa County 100-year Flood Flood hazard areas—those areas susceptible to flooding—are mapped by the Federal Emergency Management Agency (FEMA). FEMA maps do not consider future conditions. To protect such areas from flood hazards, FEMA administers the National Flood Insurance Program (NFIP). The NFIP is a federal program created to avert future flood losses through building and zoning ordinances and to provide federally backed flood insurance protection for property owners. The County is a participant in the NFIP. To support the NFIP, FEMA publishes Flood Insurance Rate Maps (FIRMs) for participating communities for flood insurance and floodplain management purposes. The FIRMs delineate different special flood hazard area zones. Special flood hazard areas associated with the 1 percent probability of annual exceedance are zones that begin with the letter “A” (e.g., Zone A, Zone AE, and Zone AO). 9 Contra Costa County. 2021.

In the County, mudflows could occur on steep slopes near Mount Diablo, Briones Regional Park, and adjacent to waterway banks. Project Site 100-year Flood According to FEMA FIRM National Flood Hazard Layer Viewer, the project site is designated Zone X— area of minimal flood hazard.11 Mudflow The project site is relatively flat and does not contain steep, unvegetated slopes susceptible to mudflows. 3.9.3 - Regulatory Framework Federal Clean Water Act The Clean Water Act (CWA) (33 United States Code [USC] § 1251, et seq.) is the major federal legislation governing the water quality aspects of construction and operation of the proposed project or variant. The CWA established the basic structure for regulating discharges of pollutants into waters of the United States (not including groundwater) and waters of the State. The objective of the CWA is “to restore and maintain the chemical, physical, and biological integrity of the nation’s waters.” The CWA establishes the basic structure for regulating the discharge of pollutants into waters of the United States. The CWA authorizes the United States Environmental Protection Agency (EPA) to implement pollution control programs. Under the CWA, it is unlawful for any person to discharge any pollutant from a point source into navigable waters, unless an NPDES permit is obtained. In addition, the CWA requires each state to adopt water quality standards for receiving water bodies and to have those standards approved by the EPA. Water quality standards consist of designated beneficial uses for a particular receiving water body (e.g., wildlife habitat, agricultural supply, fishing), along with water quality objectives necessary to support those uses. Responsibility for protecting water quality in California resides with the State Water Board and nine RWQCBs. The State Water Board establishes Statewide policies and regulations for the implementation of water quality control programs mandated by federal and State water quality statutes and regulations. The RWQCBs develop and implement water quality control plans (basin plans) that consider regional beneficial uses, water quality characteristics, and water quality problems. Water quality standards applicable to the proposed project are listed in the San Francisco Bay RWQCB Basin Plan. 11 Federal Emergency Management Agency (FEMA) National Flood Hazard Layer (NFHL) Viewer FIRMette. 2020.

Where multiple uses exist, water quality standards must protect the most sensitive use. Water quality standards are typically numeric, although narrative criteria based on biomonitoring methods may be employed where numerical standards cannot be established or where they are needed to supplement numerical standards. CWA Section 303(d) requires states and authorized Native American tribes to develop a list of water quality–impaired segments of waterways. The list includes waters that do not meet water quality standards necessary to support a waterway’s beneficial uses even after the minimum required levels of pollution control technology have been installed. Listed water bodies are to be priority ranked for development of a Total Maximum Daily Load (TMDL). A TMDL is a calculation of the total maximum daily load (amount) of a pollutant that a water body can receive on a daily basis and still safely meet water quality standards. The TMDLs include waste load allocations for urban stormwater runoff as well as municipal and industrial wastewater discharges, with allocations apportioned for individual Municipal Separate Storm Sewer Systems (MS4s) and wastewater treatment plants, including those in Contra Costa County. For stormwater, load reductions would be required to meet the TMDL waste load allocations within the 20 years required by the TMDLs. The State Water Board, RWQCBs, and EPA are responsible for establishing TMDL waste load allocations and incorporating approved TMDLs into water quality control plans, NPDES permits, and Waste Discharge Requirements (WDRs) in accordance with a specified schedule for completion. The San Francisco Bay RWQCB develops TMDLs for the Contra Costa County area. Section 401—Water Quality Certification Section 401 of the CWA requires compliance with State water quality standards for actions within State waters. Under CWA Section 401, an applicant for a Section 404 permit (to discharge dredged or fill material into waters of the United States) must first obtain a certificate from the appropriate agency stating that the fill is consistent with the State’s water quality standards and criteria. In California, the State Water Board delegates authority to either grant water quality certification or waive the requirements to the nine RWQCBs. The San Francisco Bay RWQCB is responsible for the project site. Section 402—National Pollution Discharge Elimination System Permits The RWQCBs administer the NPDES stormwater permitting program, under Section 402(d) of the federal CWA, on behalf of EPA. The objective of the NPDES program is to control and reduce levels of pollutants in water bodies from discharges of municipal and industrial wastewater and stormwater runoff. CWA Section 402(d) establishes a framework for regulating nonpoint-source stormwater discharges (33 USC § 1251). Under the CWA, discharges of pollutants to receiving water are prohibited unless the discharge complies with an NPDES permit. The NPDES permit specifies discharge prohibitions, effluent limitations, and other provisions, such as monitoring deemed necessary to protect water quality based on criteria specified in the National Toxics Rule (NTR), the California Toxics Rule (CTR), and the Basin Plan. Contra Costa County–Oak Road Townhouse Condominiums Project Hydrology and Water Quality Draft EIR 3.9-6 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-09 Hydrology.docx Discharge prohibitions and limitations in an NPDES permit for wastewater treatment plants are designed to maintain public health and safety, protect receiving water resources, and safeguard the water’s designated beneficial uses. Discharge limitations typically define allowable effluent quantities for flow, biochemical oxygen demand, total suspended matter, residual chlorine, settleable matter, total coliform, oil and grease, pH, and toxic pollutants. Limitations also typically encompass narrative requirements regarding mineralization and toxicity to aquatic life. Under the NPDES permits issued to the City/County to operate the treatment plants, the City/County is required to implement a pretreatment program. This program must comply with the regulations incorporated in the CWA and the General Pretreatment Regulations (Code of Federal Regulations [CFR] Title 40, Part 403 [40 CFR 403]). Section 404—Permitting Discharges of Dredge or Fill Material Section 404 of the CWA regulates temporary and permanent fill and disturbance of wetlands and waters of the United States. Under Section 404, the discharge (temporary or permanent) of dredged or fill material into waters of the United States, including wetlands, typically must be authorized by the United States Army Corps of Engineers (USACE) through either the Nationwide Permit (general categories of discharges with minimal effects) or the Individual Permit. River and Harbors Act Section 10 Section 10 of the Rivers and Harbors Act of 1899 requires that regulated activities conducted below the ordinary high-water elevation of navigable waters of the United States be approved and permitted by the USACE. Regulated activities include the placement or removal of structures, work involving dredging, disposal of dredged material, filling, excavation, or any other disturbance of soils/sediments or modification of a navigable waterway. Navigable waters of the United States are those waters of the United States that are subject to the ebb and flow of the tide shoreward to the mean high-water mark and/or are presently used, or have been used in the past, or may be susceptible to use to transport interstate or foreign commerce. Section 10 also regulates tributaries and backwater areas that are associated with navigable waters of the United States and are located below the ordinary high-water elevation of the adjacent navigable waterway. A project proponent can apply for a permit/letter of permission for work regulated under Section 404 (CWA) and Section 10 (Rivers and Harbors Act) by completing and submitting one application form. An application for a USACE permit will serve as an application for both Section 404 and Section 10 permits. Federal Antidegradation Policy The federal antidegradation policy is designed to protect existing water uses, water quality, and national water resources. The federal policy directs states to adopt a Statewide policy that includes the following primary provisions: • Existing instream uses and the water quality necessary to protect those uses shall be maintained and protected. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Hydrology and Water Quality FirstCarbon Solutions 3.9-7 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-09 Hydrology.docx • Where existing water quality is better than necessary to support fishing and swimming conditions, that quality shall be maintained and protected unless the State finds that allowing lower water quality is necessary for important local economic or social development. • Where high-quality waters constitute an outstanding national resource, such as waters of national and State parks, wildlife refuges, and waters of exceptional recreational or ecological significance, that water quality shall be maintained and protected. National Toxics Rule and California Toxics Rule In 1992, the EPA promulgated the NTR under the CWA to establish numeric criteria for priority toxic pollutants for 14 states to bring all states into compliance with the requirements of CWA Section 303(c)(2)(B). The NTR established water quality standards for 42 pollutants not covered under California’s Statewide water quality regulations at that time. Because of the court-ordered revocation of California’s Statewide basin plans in September 1994, the EPA initiated efforts to promulgate additional federal water quality standards for California. In May 2000, the EPA issued the CTR, which includes all the priority pollutants for which the EPA has issued numeric criteria not included in the NTR. Executive Order 11988 Executive Order 11988, “Floodplain Management,” directs all federal agencies to avoid, to the extent possible, long- and short-term adverse impacts of occupancy and modification of floodplains, and to avoid supporting development in a floodplain either directly or indirectly wherever there is a practical alternative. Compliance requirements are outlined in 23 Code of Federal Regulations 650, Subpart A, “Location and Hydraulic Design of Encroachment on Floodplains.” If a project involves significant encroachment into the floodplain, the final environmental document must include: • The reasons why the proposed action must be located in the floodplain; • Alternatives considered and the reasons they were not practical, and • A statement indicating whether the action conforms to applicable State or local floodplain protection standards. National Toxics Rule and California Toxics Rule The National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973 were enacted to reduce the need for flood protection structures and limit disaster relief costs by restricting development in floodplains. FEMA, established in 1979, is responsible for predicting hazards from flooding events and forecasting the level of inundation under various conditions. As part of its duty to develop standards for delineating fluvial and coastal floodplains, FEMA provides information on FIRMs about the potential for flood hazards and inundation and, where appropriate, designates regions as Special Flood Hazard Areas (SFHAs). SFHAs are defined as areas that have a 1 percent chance of flooding in a given year.

State Porter-Cologne Water Quality Control Act The Porter-Cologne Water Quality Control Act of 1969 (Porter-Cologne Act) is California’s statutory authority for the protection of water quality. Under the Porter-Cologne Act, the State must adopt water quality policies, plans, and objectives that protect the State’s waters for the use and enjoyment of the people. Regional authority for planning, permitting, and enforcement is delegated to the nine RWQCBs. The RWQCBs are required to formulate and adopt basin plans for all areas in the region and establish water quality objectives in the plans. The Porter-Cologne Act sets forth the obligations of the State Water Board and RWQCBs to adopt and periodically update basin plans. The San Francisco Bay RWQCB is responsible for the project site. Basin plans are the regional water quality control plans required by both the CWA and the Porter- Cologne Act that establish beneficial uses, water quality objectives, and implementation programs for each of the nine regions in California. The Act also requires waste dischargers to notify the RWQCBs of their activities by filing reports of waste discharge and authorizes the State Water Board and RWQCBs to issue and enforce WDRs, NPDES permits, CWA Section 401 water quality certifications, or other approvals. The RWQCBs are also authorized to issue waivers to reports of waste discharge and WDRs for broad categories of “low threat” discharge activities that have minimal potential to cause adverse water quality effects when implemented according to prescribed terms and conditions. California Code of Regulations (Wetlands and Waters Definition) The State Water Board indicates that no single accepted definition of wetlands exists at the State level, and that the RWQCBs may have different requirements and levels of analysis regarding the issuance of water quality certifications. Generally, an area is a wetland if, under normal circumstances: (1) the area has continuous or recurrent saturation of the upper substrate caused by groundwater, or shallow surface water, or both; (2) the duration of such saturation is sufficient to cause anaerobic conditions in the upper substrate; and (3) the area’s vegetation is dominated by hydrophytes or the area lacks vegetation. Under California State law, waters of the State mean “any surface water or groundwater, including saline waters, within the boundaries of the State.” As such, water quality laws apply to both surface water and groundwater. After the U.S. Supreme Court decision in Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers (53 USC 159), the Office of Chief Counsel of the State Water Board released a legal memorandum confirming the State’s jurisdiction over isolated wetlands. The memorandum stated that under the Porter-Cologne Act, discharges to wetlands and Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Hydrology and Water Quality FirstCarbon Solutions 3.9-9 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-09 Hydrology.docx other waters of the State are subject to State regulation, and this includes isolated wetlands. In general, the State Water Board regulates discharges to isolated waters in much the same way as it does for waters of the United States, using the Porter-Cologne Act rather than CWA authority. National Pollutant Discharge Elimination System The NPDES permits all involve similar processes, which include submitting notices of intent for discharging to water in areas under the San Francisco Bay RWQCB’s jurisdiction and implementing Best Management Practices (BMPs) to minimize those discharges. The San Francisco Bay RWQCB may also issue site-specific WDRs, or waivers to WDRs, for certain waste discharges to land or waters of the State. Construction Activity The State Water Board stormwater general permit for construction activity (Order 2009-009-DWQ, as amended by Order Nos. 2010-0014-DWQ and 2012-0006-DWQ) applies to all construction activities that would disturb 1 acre of land or more. Construction activities subject to the general construction activity permit include clearing, grading, stockpiling, and excavation. Dischargers are required to eliminate or reduce non-stormwater discharges to storm sewer systems and other waters. Through the NPDES and WDR processes, the State Water Board seeks to ensure that the conditions at a project site during and after construction do not cause or contribute to direct or indirect impacts on water quality (i.e., pollution and/or hydromodification) upstream and downstream. To comply with the requirements of the Construction General Permit, the project applicant must file a notice of intent with the State Water Board to obtain coverage under the permit; prepare a Storm Water Pollution Prevention Plan (SWPPP); and implement inspection, monitoring, and reporting requirements appropriate to the proposed project’s risk level as specified in the SWPPP. The SWPPP includes a site map, describes construction activities and potential pollutants, and identifies BMPs that will be employed to prevent soil erosion and discharge of other construction-related pollutants that could contaminate nearby water resources, such as petroleum products, solvents, paints, and cement. The permit also requires the discharger to consider using post-construction permanent BMPs that will remain in service to protect water quality throughout the life of the project. All NPDES permits also have inspection, monitoring, and reporting requirements. Project sites served by the combined sewer system are not required to obtain coverage under the NPDES Construction General Permit. Industrial General Stormwater Permit The Statewide stormwater NPDES permit for general industrial activity (Order 2014-0057-DWQ, superseding Order 97-03-DWQ) regulates discharges associated with 10 broad categories of industrial activities, such as operation of wastewater treatment works, and with recycling facilities. The industrial general permit requires the implementation of Best Available Technology Economically Achievable and Best Conventional Pollutant Control Technology to achieve performance standards. The permit also requires development of a SWPPP that identifies the site-specific sources of pollutants and describes the measures at the facility applied to reduce stormwater pollution. A monitoring plan is also required.

Phase I of the permitting program applied to municipal discharges of stormwater in urban areas where the population exceeded 100,000 persons. Phase II of the NPDES stormwater permit regulations, which became effective in March 2003, required that NPDES permits be issued for construction activity for projects disturbing 1–5 acres. Phase II of the municipal permit system (known as the NPDES General Permit for Small MS4s, Order No. 2003-0005-DWQ as amended by 2013-0001-DWQ) required small municipalities of fewer than 100,000 persons to develop stormwater management programs. This permit authorizes discharges of stormwater and some categories of non-stormwater that are not “significant contributors of pollutants.” California Toxics Rule and State Implementation Policy The CTR, presented in 2000 in response to requirements of EPA’s NTR, establishes numeric water quality criteria for approximately 130 priority pollutant trace metals and organic compounds. The CTR criteria are regulatory criteria adopted for inland surface waters, enclosed bays, and estuaries in California that are on the CWA Section 303(c) list for contaminants. The CTR includes criteria for the protection of aquatic life and human health. Human health criteria (water- and organism-based) apply to all waters with a municipal and domestic water supply beneficial use designation as indicated in the basin plans. The Policy for Implementation of Toxics Standards for Inland Surface Waters, Enclosed Bays, and Estuaries of California, also known as the State Implementation Policy, was adopted by the State Water Board in 2000. It establishes provisions for translating CTR criteria, NTR criteria, and basin plan water quality objectives for toxic pollutants into: • NPDES permit effluent limits. • Effluent compliance determinations. • Monitoring for 2,3,7,8-tcdd (dioxin) and its toxic equivalents. • Chronic (long-term) toxicity control provisions. • Site-specific water quality objectives. • Granting of effluent compliance exceptions. The goal of the State Implementation Plan is to establish a standardized approach for permitting discharges of toxic effluent to inland surface waters, enclosed bays, and estuaries throughout the State. Local Contra Costa County General Plan Conservation Element The General Plan Conservation Element sets forth the following applicable goals, policies, and implementation measures that are relevant to hydrologic resources: Goal 8-T To conserve, enhance, and manage water resources, protect their quality, and assure an adequate long-term supply of water for domestic, fishing, industrial and agricultural use.

Goal 8-V To preserve and restore remaining natural waterways in the County which have been identified as important and irreplaceable natural resources. Goal 8-W To employ alternative drainage system improvements which rely on increased retention capacity to lessen or eliminate the need for structural modifications to watercourses, whenever economically possible. Goal 8-X To enhance opportunities for public accessibility and recreational use of creeks, streams, drainage channels and other drainage system improvements. Policies Policy 8-74 Preserve watersheds and groundwater recharge areas by avoiding the placement of potential pollution sources in areas with high percolation rates. Policy 8-75 Preserve and enhance the quality of surface and groundwater resources. Policy 8-77 Provide development standards in recharge areas to maintain and protect the quality of groundwater supplies. Policy 8-78 Where feasible, existing natural waterways shall be protected and preserved in their natural state, and channels which already are modified shall be restored. A natural waterway is defined as a waterway which can support its own environment of vegetation, fowl, fish, and reptiles, and which appears natural. Policy 8-79 Creeks and streams determined to be important and irreplaceable natural resources shall be retained in their natural state whenever possible to maintain water quality, wildlife diversity, aesthetic values, and recreation opportunities. Policy 8-82 Riparian habitat shall be protected by providing for channel cross-sections adequate to carry 100-year flows, as per policies contained in the Public Facilities/Services Element. If it is not possible to provide a channel cross section sufficient to carry the 100-year flow, then detention basins should be developed. Policy 8-86 Existing native riparian habitat shall be preserved and enhanced by new development unless public safety concerns require removal of habitat for flood control or other public purposes. Policy 8-87 On-site water control shall be required of major new developments so that no increase in peak flows occurs relative to the site’s pre-development condition, unless Planning Agency determines that off-site measures can be employed which are equally effective in preventing adverse downstream impacts.

Policy 8-92 Revegetation of a watercourse shall employ native vegetation, providing the type of vegetation is compatible with the watercourse's maintenance program and does not adversely alter channel capacity. Implementation Measure 8-cy Through the environmental review process, the likely effects of construction and other proposed activities on nearby natural watercourses and related open space shall be determined. Measures shall be identified that will mitigate these effects and encourage the preservation of natural waterways and related open space. Such measures may include, but are not limited to: (1) Clustering of buildings and other site design features; (2) Restoration or enhancement of other riparian habitat within or near the project area; and (3) Purchase of development rights for lands within other stream setback areas. Contra Costa County Ordinance Code Division 914 of the Ordinance Code addresses drainage. Section 914-2.002 requires that all portions of a subdivision shall be protected from flood hazards and storm drainage facilities within the subdivision shall be designed and constructed in compliance with current specifications and design standards of the Public Works Department. Division 1014, Stormwater Management and Discharge Control, carries out the conditions in the County’s NPDES Permit issued by the San Francisco Bay RWQCB that require implementation of appropriate source control and site design measures and stormwater treatment measures for projects that create or replace 1 acre or more of impervious surface. Contra Costa County Green Infrastructure Plan The County Green Infrastructure Plan provides a blueprint for how the County will add to and replace its “gray” infrastructure system of pipes and storm drains with “green” infrastructure or Low Impact Development (LID) practices throughout unincorporated areas. The Green Infrastructure Plan is a requirement of the NPDES Municipal Regional Stormwater Permit, issued by the San Francisco Bay RWQCB on November 19, 2015.12 The intent of the Green Infrastructure Plan is to demonstrate how the County will move away from traditional stormwater infrastructure and toward green stormwater infrastructure to mitigate some of the impacts of urbanization on water quality to the creeks, waterways, and the San Francisco Bay. The focus of the County Green Infrastructure Plan is the integration of stormwater treatment into County-owned properties, parking lots, and road right- of-way. As a long-term (2020-2040) blueprint, it seeks to show how the County intends to gradually 12 Contra Costa County Public Works. 2019. Green Infrastructure Plan.

This area was selected for its location adjacent to old urban land uses where stormwater pollutants are the highest. 3.9.4 - Impacts and Mitigation Measures Significance Criteria According to the California Environmental Quality Act (CEQA) Guidelines Appendix G Environmental Checklist, to determine whether impacts related to hydrology and water quality are significant environmental effects, the following questions are analyzed and evaluated. Would the proposed project: a) Violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality? b) Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the proposed project may impede sustainable groundwater management of the basin? c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: i) result in substantial erosion or siltation on- or off-site; ii) substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site; iii) create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; or iv) impede or redirect flood flows? d) In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation? e) Conflict with or obstruct implementation of a Water Quality Control Plan or sustainable groundwater management plan? Approach to Analysis Impacts related to hydrology and water quality were determined by reviewing information regarding regional and local hydrology, climate, topography, and geology contained in the General Plan, San Francisco Bay RWQCB Basin Plan, FEMA FIRMs, project utility plans, and the site-specific Drainage Study and Stormwater Control Plan (Appendix G). Contra Costa County–Oak Road Townhouse Condominiums Project Hydrology and Water Quality Draft EIR 3.9-14 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-09 Hydrology.docx The evaluation of impacts is based on a comparison of existing conditions to anticipated conditions once the proposed project is constructed and operational, such as changes in impervious area, as well as facilities potentially located within flood zones. Specifically, the impact evaluation focuses on the effect of the proposed project on surface and groundwater quality, groundwater supply, and drainage (in terms of erosion, siltation, flooding, stormwater system exceedance, and polluted runoff). Water quality conditions are compared with water quality standards and WDRs by identifying potential contaminants and pollution pathways, amount of impervious area, and runoff treatment requirements. Finally, as part of the analysis, inundation and flooding on the project site is assessed by reviewing potential inundation zone elevations relative to the final grade elevations of facilities and features for the proposed project. Specific Thresholds of Significance For purposes of this analysis, the following thresholds are used to evaluate the significance of hydrology and water quality impacts resulting from implementation of the proposed project. • Violate any water quality standards or waste discharge requirements established by a regulatory body with jurisdiction over the project area. • Deplete groundwater supplies or interfere with groundwater recharge such that the production rate or volumes of wells or aquifers would drop. • Alter an existing drainage pattern through alteration of the course of a stream or river or increased impervious surfaces and resulting in erosion, siltation, or flooding on- or off-site. • Create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff. • Expose people to pollutants due to inundation related to flooding, tsunami, or seiche. • Conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan. Impact Evaluation Surface and Groundwater Quality Impact HYD-1: The proposed project would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality. Construction Construction activities, including the areas proposed for off-site improvements, would expose soils on the project site to potential water erosion and construction equipment-related pollutants. Runoff from graded areas could carry eroded soils and pollutants into the storm drainage systems and into the Walnut Creek, increasing sedimentation and degrading downstream water quality. These sediments also could be carried downstream and discharged into the Suisan Bay leading to the San Francisco Bay and ultimately into the Pacific Ocean, degrading surface water quality, or allowed to seep into the associated groundwater table. This would represent a potentially significant construction impact related to surface and groundwater quality.

The Preliminary Geotechnical Exploration further states that the project site has areas of shallow ground water which could affect the proposed development.14 Specifically shallow groundwater can (i) impede grading operations, (ii) require dewatering during grading and construction of improvements, (iii) cause moisture damage to sensitive floor coverings, and (iv) transmit moisture vapor through slabs, causing buildup of mold/mildew, fogging of windows and damage to computers and other sensitive equipment. Based on the existing data groundwater depths on-site, removal of existing fill on the site and deep utility trench excavation may encounter groundwater. The project contractor should evaluate site conditions and select properly designed dewatering and shoring systems. Groundwater levels may fluctuate seasonally, and may be significantly influenced by irrigation of plantings, water and/or sewer leaks and other factors.15 Given that proposed construction would disturb more than 1 acre of land, the proposed project would be required to comply with the terms of the NPDES permits and the Contra Costa County Ordinance Code Chapter 1014-4, which requires the preparation and implementation of a SWPPP. The SWPPP includes BMPs to ensure reduction of pollutants from construction activities potentially entering surface waters. Additionally, implementation of the SWPPP would also prevent pollutants from entering the Ygnacio Valley Basin by preventing pollutants from moving off-site. Although construction activities have the potential to generate increased sedimentation, compliance with applicable policies and regulations would minimize the potential to degrade water quality in downstream water bodies to the maximum extent possible. As a result, construction-related project impacts related to surface and groundwater, and respective water quality would be less than significant. Operation The project site is located in an urbanized area with mostly impervious surfaces. Project operation would generate runoff, which may carry pollutants such as pesticides, fertilizers, and deposits of fluids and metals from motor vehicles into the Contra Costa Canal or allow seepage of such pollutants into the associated groundwater table. This would represent a potentially significant operational impact related to surface and groundwater quality. The proposed project would increase impervious surfaces by 36,420 square feet compared to existing conditions,16 and therefore could generate increased amounts of runoff that could carry pollutants into the Contra Costa Canal or the Ygnacio Valley Basin. However, the proposed project 13 Roux Associates, Inc. 2021. Phase I Environmental Site Assessment and Limited Phase II Environmental Investigation Report 2740 Jones Road Walnut Creek, California.

As described in the Preliminary Hydrology and Hydraulics Calculations Control Plan, the on-site storm drain system has been designed to meet the County’s hydraulic requirements. Based on the hydrograph and hydromodification calculations, it appears on-site storage facilities of 2,800 cubic feet would be needed to mitigate the potential increase of post-development flows and to meet the hydromodification requirements. To meet this requirement, two underground storage vaults are proposed to capture, store, and release the post-development storm flow into the existing off-site storm drainage facilities. These two vaults are placed at the downstream ends of the on-site storm drains at the respective discharge points at Oak Road and Jones Road.17 As described in the Preliminary Stormwater Control Plans, the proposed project would utilize and integrate the bioretention technique and approach to meet the LID treatments in compliance with the requirements set forth in the County C.3 Technical Guidance. Bioretention functions as soil and plant-based filtration that removes pollutants through a variety of physical, biological, and chemical process. These facilities consist of a layer of cobble stone (mulch is not recommend), planted landscape (grass, shrub, or trees), sandy loam soil (with a minimum percolation rate of 5 inches/hour and a maximum percolation rate of 10 inches/hour), drain rock and under drains. The stormwater runoff from impervious surface is directed and passed through the bioretention areas and distributed evenly along a ponding area. Stormwater runoff will percolate through the sandy loam treatment soil and eventually captured by the under drains and discharged into the underground storm drains.18 Due to the nature of the development and space needed for utilities, underground utility boxes, transformers, and backflow devices, etc., there is limited available open space or landscape area for treatment purposes. Given the physical constraints and limitations, treatment would be optimized by breaking up the new and/or replaced impervious areas in small drainage management areas and using drainage swales, curb openings, and bubble ups to convey the runoff to the treatment areas in paseos, landscape pockets between walkways/buildings and the center open space area on the project site. By implementing this approach, LID bioretention treatment areas are dispersed throughout the site, enabling the project to treat 100 percent of the impervious surface with the bioretention measures.19 Therefore, operation-related project impacts related to surface and groundwater, and water quality would be less than significant. 17 Ruggeri-Jensen-Azar. 2021.

Groundwater Supply/Recharge Impact HYD-2: The proposed project would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the proposed project may impede sustainable groundwater management of the basin. Construction Impacts related to depletion of groundwater supplies or interference with groundwater recharge are limited to operational impacts. No construction impacts would occur in the project site because construction activities would not involve the use of groundwater. Operation As detailed in the Phase I Environmental Site Assessment and Limited Phase II Investigation Report, the three irrigation wells located on the project site would be decommissioned prior to redevelopment.20 The proposed project would increase impervious surfaces by 36,420 square feet compared to existing conditions.21 However, the proposed project would incorporate LID techniques as described above in the Impact HYD-1 discussion. In addition, as described in Section 3.14, Utilities and Services Systems, the Contra Costa Water District would be able to provide adequate water services to the project site and the rest of its service area during normal, dry, and multiple dry years, and no groundwater would be used. Thus, the project would not interfere substantially with groundwater supply, recharge, or groundwater management. Therefore, impacts related to groundwater recharge and supply would be less than significant. Level of Significance Less than significant impact. Drainage Leading to Erosion/Siltation, Flooding, Additional Sources of Polluted Runoff, or Impedance of Flood Flows Impact HYD-3: The proposed project could substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river or through the addition of impervious surfaces, in a manner which would: i) result in substantial erosion or siltation on- or off-site; (ii) substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site; 20 Roux Associates, Inc. 2021.

Contra Costa County–Oak Road Townhouse Condominiums Project Hydrology and Water Quality Draft EIR 3.9-18 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-09 Hydrology.docx (iii) create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; or (iv) impede or redirect flood flows? i) Construction-related Erosion and Siltation The proposed project would have a significant impact if it were to substantially alter the existing drainage pattern of the site in a manner that would result in substantial erosion or siltation on- or off-site. Such drainage effects could occur from grade changes at the project site, exposure of soils for periods of time during stormwater discharge, or alterations to creek beds. These types of changes would have a potentially significant impact related to on-site drainage patterns. The proposed project would involve construction in an area that is currently characterized almost entirely by impervious surfaces, and the on-site drainage and storm runoff generally sheet flows across the site or is captured by small drainage inlets on-site that are connected by underground storm drain pipes and discharge into existing storm drain facilities in Jones Road and Oak Road. Construction activity, such as grading and excavation, could result in an alteration to this drainage pattern, potentially resulting in erosion or siltation that could result in polluted runoff exiting the site. This would represent a potentially significant impact. Implementation of Mitigation Measure (MM) HYD-3 would ensure the proposed project complies with regulations of the NPDES permit consistent with Division 1014 of the Ordinance Code. Additionally, as part of compliance with Division 1014 of the Ordinance Code, the proposed project would also be required to prepare and implement a SWPPP to ensure that erosion, siltation, and flooding are prevented or minimized to the maximum extent feasible during construction. The SWPPP includes both structural (physical devices or measures) and operational (timing of construction) BMPs that would prevent or reduce the discharge of pollutants directly or indirectly into waterbodies. As part of the SWPPP, erosion and control measures would be implemented throughout the duration of construction, including rock barrier bags placed around the catch basin until the site is paved, temporary sediment basins, placement of coarse aggregate gravel at each driveway entrance to the site such that mud or sediments would not be tracked off-site by construction vehicles, and maintaining the site to minimize sediment from entering any storm drain system in stormwater runoff. Therefore, the construction impact related to alteration of drainage patterns resulting in erosion or siltation would be less than significant. Operation-related Erosion and Siltation The project site is in an urbanized area and primarily consists of impervious surfaces. Development of the project site would increase impervious surfaces by 36,420 square feet compared to existing conditions,22 and could result in increased amounts of stormwater runoff that could carry pollutants off-site. 22 Ruggeri-Jensen-Azar. 2021.

MM HYD-3 would also require the project applicant to prepare and submit a Final Storm Water Control Plan and Stormwater Control Operation and Maintenance Plan for review and approval by the County Public Works Department. Implementation of MM HYD-3 would ensure a permanent funding source for the operation and maintenance of project stormwater facilities, which would result in a reduction of stormwaters flowing from the site compared to the current condition (see also Section (iii) below). In addition, the proposed project would comply with the County’s NPDES program and the CCCWP as well as all relevant provisions of the Ordinance Code related to stormwater pollution, and would also be required to pay drainage fees in accordance with Flood Control Ordinance number 89-24. Therefore, the potential operational impacts related to alteration of drainage pattern resulting in erosion or siltation would be less than significant. ii) Construction-related Surface Runoff As described previously, implementation of MM HYD-3 would ensure the proposed project would comply with regulations of the NPDES permit consistent with Division 1014 of the Ordinance Code. Additionally, as part of compliance with the Ordinance Code, the proposed project would be required to prepare and implement a SWPPP to ensure that erosion, siltation, and flooding are prevented or minimized to the maximum extent feasible during construction. The SWPPP would include both structural (physical devices or measures) and operational (timing of construction) BMPs that would prevent or reduce the amount of stormwater runoff that could be deposited directly or indirectly into waterbodies. As part of the SWPPP, erosion and control measures would be implemented throughout the duration of construction that would also limit the volume of stormwater that would be discharged. These measures would include rock barrier bags placed around the catch basin until the site is paved, and temporary sediment basins that would retain stormwater to prevent significant peak flows. As such, construction impacts related to flooding would be less than significant with mitigation incorporated. Operation-related Surface Runoff The proposed project would develop a 5.94-acre project site that is currently composed of mostly impervious surfaces. Under existing conditions, stormwater runoff generally sheet flows across the site or is captured by small drainage inlets on-site that connect by underground storm drain pipes and discharge into existing storm drain facilities in Jones Road and Oak Road. The proposed project would increase impervious surfaces by 36,420 square feet compared to existing conditions,23 which could increase surface runoff and potentially cause flooding on- or off- site. This would represent a potentially significant impact. The applicant would be required to comply with Division 914 of the Ordinance Code, which addresses drainage, including provisions requiring appropriate collection and conveyance. The applicant would also be required to implement MM HYD-3, which would ensure that the site discharges to facilities with adequate capacity, and that downstream facilities, if necessary, be made 23 Ruggeri-Jensen-Azar. 2021.

As part of the proposed on-site drainage improvements, runoff from impervious areas on the project site would be routed to 34 bioretention areas for treatment before being discharged into underground storm drains; these improvements would ensure that post-construction surface runoff would be less than existing conditions. Therefore, operation of the proposed project would not result in substantial off-site flooding. iii) Construction-related Exceedance of Storm Drain Capacity During construction, the proposed project could increase stormwater runoff generation, which could potentially lead to flooding on or off-site. However, the proposed project would be required to implement a SWPPP as part of its Construction General Permit to ensure that stormwater generation and pollutants are prevented or minimized to the maximum extent feasible during construction through the implementation of standard BMPs. Therefore, the construction impact related to exceedance of storm drain capacity and stormwater pollution would be less than significant. Operation-related Exceedance of Storm Drain Capacity The proposed project would not increase impervious surfaces compared to existing conditions, and therefore is not likely generate increased amounts of runoff. As described in the Stormwater Control Plan, the proposed project would incorporate LID techniques to allow for stormwater infiltration and treatment in 34 bioretention areas before being discharged to the storm drain system. The proposed project would use 100 percent LID, meaning 100 percent of project runoff would be contained and treated on-site before being discharged. This would be accomplished by optimizing site layout and by and by using drainage swales, curb openings, and bubble ups to convey the runoff to the treatment areas in paseos, landscape pockets between walkways/buildings and the center open space area on the project site. Furthermore, compliance with the CCCWP and the Ordinance Code would ensure that project operation would not create runoff that exceeds the capacity of existing or planned stormwater drainage systems or provide sources of stormwater or polluted runoff. Thus, operation of the project would not create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems (see Impact UTIL-1) or provide substantial additional sources of polluted runoff. Therefore, the operational impact related to additional sources of polluted runoff would be less than significant. iv) Construction-related Impacts to Flood Flows Impacts related to impedance of flood flows would only occur during the operational phase of the project. As such, no construction impedance of flood flow impacts would occur. Operation-related Impacts to Flood Flows As described in the Environmental Setting, the project site is designated Zone X—area of minimal flood hazard. As described in further detail under Impact HYD-4, the project site is not susceptible to inundation from flood hazards, tsunamis, or seiches. As a result, the proposed project is not anticipated to have any effect in terms of impeding or redirecting flood flows. Therefore, impacts would be less than significant.

Mitigation Measures MM HYD-3 Prepare Final Drainage Plan Prior to Grading • In accordance with Division 914 of the County Ordinance Code, the project shall collect and convey all stormwater entering and/or originating on this property, without diversion and within an adequate storm drainage facility, to a natural watercourse having definable bed and banks, or to an existing adequate public storm drainage system that conveys the stormwater to a natural watercourse. Any proposed diversions of the watershed shall be subject to hearing body approval. Prior to issuance of a grading permit, the applicant shall obtain a Flood Control Permit from the applicant and Permit Center, submit improvement plans for proposed drainage improvements, and a drainage report with hydrology and hydraulic calculations to the Engineering Services Division of the Public Works Department for review and approval that demonstrates the adequacy of the in- tract drainage system and the downstream drainage system. The applicant shall verify the adequacy at any downstream drainage facility accepting stormwater from this project prior to discharging runoff. If the downstream system(s) is not adequate to handle the Existing Plus Project condition for the required design storm, improvements shall be constructed to make the system adequate. The applicant shall obtain access rights to make any necessary improvements to off- site facilities. • In accordance with Division 1014 of the County Ordinance Code, the applicant shall comply with all rules, regulations, and procedures of the National Pollutant Discharge Elimination System (NPDES) for municipal, construction, and industrial activities as promulgated by the California State Water Resources Control Board, or any of its Regional Water Quality Control Boards (San Francisco Bay—Region 2); and • Submit a Final Stormwater Control Plan and a Stormwater Control Operation and Maintenance Plan (O&M Plan) to the Public Works Department, which shall be reviewed for compliance with the County’s NPDES Permit and shall be deemed consistent with the County’s Stormwater Management and Discharge Control Ordinance (Division 1014) prior to issuance of a building permit. Improvement Plans shall be reviewed to verify consistency with the Final Stormwater Control Plan and compliance with the Contra Costa Stormwater C.3 Guidebook of the County’s NPDES Permit and the County’s Stormwater Management and Discharge Control Ordinance (Division 1014) and be designed to discourage prolonged standing/ponding of water on-site. Level of Significance After Mitigation Less than significant impact.

Construction Impacts related to inundation are limited to operational impacts. As such, no construction impacts would occur. Operation As described previously, FEMA designates the project site Zone X—area of minimal flood hazard.24 The closest designated 100-year flood hazard zone to the project site is Walnut Creek, located approximately 0.46 miles to the east.25 Therefore, the project site is not located within a recognized flood hazard area. The project site is not located near the ocean, and as such would not be susceptible to inundation from a tsunami. The project site is not located near a large, enclosed body of water and as such would not be susceptible to inundation from a seiche. As a result, the project site would not be a risk for inundation from flooding, tsunami, or seiche. Therefore, impacts related to risk of pollutant release due to inundation would be less than significant. Level of Significance Less than significant impact. Water Quality Control or Sustainable Groundwater Management Plans Consistency Impact HYD-5: The proposed project would not conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan. Construction The proposed project would not conflict with the County Watershed Program and the County’s NPDES program. Given that proposed construction would disturb more than 1 acre of land, the proposed project would be required to comply with the terms of the Construction General Permit, which require the preparation and implementation of a SWPPP that includes BMPs to ensure reduction of pollutants from construction activities potentially entering surface or groundwater. Therefore, construction impacts related to water quality control plan or groundwater management plan consistency would be less than significant. Operation The project site is located within the Ygnacio Valley Groundwater Basin. The project site has little potential for groundwater recharge due to shallow groundwater levels. In addition, the Contra Costa Water District would provide potable water to the project site and the project would not use groundwater as a water source. As a result, the project would not conflict with or obstruct a 24 Federal Emergency Management Agency (FEMA) National Flood Hazard Layer (NFHL) Viewer FIRMette. 2020.

Therefore, operational impacts related to a water quality control plan or groundwater management plan consistency would be less than significant. Level of Significance Less than significant impact. 3.9.5 - Cumulative Impacts Hydrology Cumulative impacts related to hydrology and water quality typically occur within a defined watershed. All properties on the cumulative projects list in Table 3-1 are located within the Walnut Creek Watershed, and all respective surface water in the watershed eventually discharges into Suisun Bay. Some cumulative projects are located within Contra Costa County, including the project, and would be required to comply with the CCCWP and Contra Costa County General Plan policies, which prevent a project from increasing off-site surface water flow from existing conditions and ensure that projects adhere to best practices during construction to prevent pollutants from being carried off-site. Some cumulative projects are located in the Cities of Walnut Creek and Pleasant Hill. Cumulative development in the City of Walnut Creek would be required to demonstrate consistency with the City of Walnut Creek General Plan and applicable codes, ordinances, and policies related to preventing pollutants from being conveyed off-site. Cumulative development in the City of Pleasant Hill would be required to demonstrate consistency with the City of Pleasant Hill General Plan and applicable codes, ordinances, and policies related to preventing pollutants from being conveyed off-site. The combination of these policies and best practices would prevent significant cumulative impacts to hydrology. Thus, there would be a less than significant cumulative impact related to hydrology. Water Quality The geographic context for consideration of cumulative impacts related to surface water quality is the Walnut Creek Watershed. All cumulative projects, including the project, would involve short- term construction and long-term operational activities that would have the potential to degrade water quality in downstream water bodies, including Walnut Creek and Suisun Bay. All cumulative project construction would be required to obtain a Construction General Permit from the State Water Board, which would require preparation of a SWPPP that would control potential discharges of contaminants into Walnut Creek and Suisun Bay. Operations of these cumulative projects would be required to comply with the CCCWP, County Ordinance Code regarding stormwater, or the Cities of Walnut Creek and Pleasant Hill applicable codes, ordinances, and policies related to water quality. Development in the County would be required to implement similar measures in accordance with adopted regulations, while projects would be subject to the Construction General Permit if applicable. Development in the City of Walnut Creek would be required to implement similar measures in accordance with adopted regulations, while projects would be subject to the Construction General Permit if applicable. Development in the City of Pleasant Hill would be required to implement similar measures in accordance with adopted regulations, while projects would be subject to the Construction General Permit if applicable. Thus, there would be a less than significant cumulative impact related to surface water quality.

All cumulative projects, including the project, would involve short-term construction and long-term operational activities that would have the potential to impact groundwater quality and management. All cumulative project construction would be required to obtain a Construction General Permit from the State Water Board, which would require preparation of a SWPPP that would control pollutants that could seep into groundwater. Operations of cumulative projects in Contra Costa County would be required to comply with the CCCWP and the County Ordinance Code regarding groundwater. Operations of cumulative projects in Walnut Creek would be required to comply with the CCCWP and the City of Walnut Creek Ordinance Code regarding groundwater. Operations of cumulative projects in Pleasant Hill would be required to comply with the CCCWP and the City of Pleasant Hill Ordinance Code regarding groundwater.

This section also evaluates the possible impacts related to land use and planning that could result from implementation of the proposed project. Information included in this section is based on review of applicable land use policies and regulations, including the Contra Costa General Plan (General Plan) and Contra Costa County Ordinance Code (Ordinance Code). During the Notice of Preparation (NOP) comment period, the following comments were received related to the proposed project regarding land use and planning: • Concern that the setback between the proposed project Buildings F, G, and H are too close to neighboring buildings. References larger setbacks between other neighborhood communities. • Various concerns due to the proposed heights of proposed Buildings F, G, and H. • Concern that the proposed project would increase density. • Provided examples of setback between existing developments along Oak Road in the vicinity of the proposed project, which are larger than with those associated with the proposed project. • Neighboring residents asking for neighboring residents are asking for larger setback due to various concerns. • Offered less dense, community-oriented alternatives to the proposed project. • Concern that the roof decks would exceed the allowed height for P-1 zoning and will be significantly taller than the surrounding community. • Request to have a discussion with the County and the developer to come up with a plan that would consider the setbacks and building heights and sizes. • Privacy concerns due to the small setback. • Stated that the northern property line of the proposed project is the front yard of the adjacent development. 3.10.2 - Environmental Setting Existing Land Use Activities Surrounding Area West Jones Road bounds the project site on the west; to the west of Jones Road is I-680, with commercial and multi-family uses, and Bay Area Rapid Transit (BART) tracks.

Office uses are located north of Jones Road and Treat Boulevard. The nearest BART station (Pleasant Hill/Contra Costa Centre Station) is located approximately 0.35-mile northeast of the project site. East Oak Road bounds the project site to the east, with multi-family residential uses across Oak Road. South There are multi-family residential uses to the south of the project site. The Contra Costa Canal and Trail is located approximately 470 feet south of the project site. Project Site The 5.94-acre project site consists of eight parcels; refer to Exhibit 2-5 in Section 2, Project Description. The project site is relatively flat (approximately 90 and 95 feet above mean sea level). The regional topographic gradient slopes gently to the northeast. The site is developed with structures associated with the former Palmer School for Boys and Girls, a private elementary school which operated at the project site from 1939 until its closure due to COVID-19 in June 2020. The former school consists of 14 vacant buildings and associated structures, including classrooms, an auditorium, a front office, a paved courtyard, a grass field, tennis courts, basketball courts playgrounds, a swimming pool, parking lots and planters. Multiple storage sheds are present on the school site. The classrooms, located in the southern portion of the school site, are generally empty or used as storage rooms for classroom materials. Situated outside of the classrooms are rows of lockers, bathrooms, and a janitorial supply closet with a boiler. A landscaping area behind the classrooms along the southern boundary of the project site includes planter boxes, storm drain lines, and power boxes, and a partially uncovered pipe which appears to be related to storm drainage. In the southeast corner of the project site is a 2-story auditorium formerly used as a storage area containing a kitchen, stage, water heater, and empty storage rooms on the second floor. Structures in the northern portion of the project site are associated with previous residential uses that were converted into storage areas for the school; these structures are currently occupied by the property owners’ family members serving as caretaker and security for the property and existing improvements. Land Use Designations and Zoning Surrounding Area The project site borders the City of Walnut Creek on the west and east sides; land uses to the north and south are located in unincorporated Contra Costa County.

Plan Bay Area functions as the sustainable communities’ strategy mandated by Senate Bill (SB) 375. As a regional land use plan, Plan Bay Area aims to reduce per capita greenhouse gas (GHG) emissions through the promotion of more compact, mixed-use residential and commercial neighborhoods located near transit. Plan Bay Area is built on Priority Development Areas selected and approved by city and county governments with planning grants, technical assistance, and prioritization for regional and State transportation and affordable housing funds. Plan Bay Area is a limited and focused update that builds upon a growth pattern and Contra Costa County–Oak Road Townhouse Condominiums Project Land Use and Planning Draft EIR 3.10-4 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-10 Land Use.docx strategies developed in the original Plan Bay Area (adopted by MTC in 2013) but with updated planning assumptions that incorporate key economic, demographic, and financial trends from the last 4 years. Plan Bay Area 2050 is currently in process by the MTC and ABAG. Plan Bay Area 2050 focuses on four key issues: The economy, the environment, housing, and transportation. This new regional plan outlines strategies for growth and investment through the year 2050, while simultaneously striving to meet and exceed federal and state requirements. The MTC and ABAG are expected to adopt Plan Bay Area 2050 in fall 2021.1 Regional Housing Need Plan In December 2013, ABAG projected regional housing needs in its Regional Housing Needs Plan for the San Francisco Bay Area: 2015–2023.2 According to this Plan, unincorporated Contra Costa County’s projected housing need from 2015 to 2023 is 1,367 residential units, consisting of: • 374 units within the very-low-income level (0–50 percent of area median income); • 218 units within the low-income level (51–80 percent of area median income); • 243 units within the moderate-income level (81–120 percent of area median income); and • 532 units within the above-moderate-income level (more than 120 percent of area median income). The Draft Regional Housing Needs Allocation (RHNA) Methodology and Final RHNA Subregional Shares for the San Francisco Bay Area, 2023-2031, were approved by the ABAG Executive Board on January 21, 2021. The release of the Draft Allocations in which a local jurisdiction or the California Department of Housing and Community Development (HCD) can submit an appeal to any Bay Area jurisdiction’s allocation is summer and fall 2021. Final Allocations are expected to be adopted in late 2021.3 According to the RHNA Draft Methodology: San Francisco Bay Area, 2023-2031, unincorporated Contra Costa County’s draft projected housing need from 2023-2031 is 7,645 residential units, consisting of: • 2,082 units within the very-low-income level (0–50 percent of area median income); • 1,199 units within the low-income level (51–80 percent of area median income); • 1,217 units within the moderate-income level (81–120 percent of area median income); and • 3,147 units within the above-moderate-income level (more than 120 percent of area median income).4 1 Plan Bay Area 2050. 2021.

The General Plan contains the following elements: Land Use, Growth Management, Transportation and Circulation, Housing, Public Facilities and Services, Conservation, Open Space, Safety, and Noise. Within each element, the County General Plan sets forth goals, policies, and implementation measures to guide future development and land use activities. Goals provide a description of general community values and set the direction for more specific policies and implementation programs related to public health, safety, or general welfare. Policies are based upon goals and provide a specific statement intended to guide the decision-making body. Implementation measures are specific actions, procedures, programs, or techniques that carry out policies. General Plan Land Use Element The General Plan Land Use Element includes land use goals, objectives, and policies, as well as a Land Use Element Map. The map illustrates land use designations throughout the County. The Land Use Element Map designates the site MH (Chapter 2, Project Description, Exhibit 2-3). Pursuant to the General Plan Land Use Element, the MH designation allows between 22.0 and 29.9 multiple- family units per net acre, and residential units can range up to 1,979 square feet. Primary land uses include attached single-family residences (such as duplexes or duets), multiple-family residences such as condominiums, town houses, apartments, mobile home parks as well as accessory buildings and structures ancillary to the primary uses. Secondary land uses that do not conflict with primary uses may also be allowed. These include churches, accessory dwelling units, home occupations, and group care and/or childcare facilities.5 The following General Plan goals and policies that are applicable to the proposed project: Land Use Element Goal 3-A To coordinate land use with circulation, development of other infrastructure facilities, and protection of agriculture and open space, and to allow growth and the maintenance of the County’s quality of life.

Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Land Use and Planning FirstCarbon Solutions 3.10-15 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-10 Land Use.docx 3.10.4 - Impacts and Mitigation Measures Significance Criteria According to California Environmental Quality Act (CEQA) Guidelines Appendix G, to determine whether impacts related to land use and planning are significant environmental effects, the following questions are analyzed and evaluated. Would the project: a) Physically divide an established community? b) Cause a significant environmental impact due to conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect? Approach to Analysis Analysis in this section focuses on whether project implementation would physically divide an established community and whether the proposed project would conflict with land use plans, policies, or regulations adopted to avoid or mitigate an environmental effect. Conflicts and inconsistencies with a policy, in and of themselves, do not constitute significant environmental impacts, unless such conflicts or inconsistencies result in direct physical environmental impacts. Physical project impacts are discussed throughout Chapter 3, Environmental Impact Analysis, of this Draft Environmental Impact Report (Draft EIR). The potential for land use impacts was assessed through review of applicable land use policy documents. Specific Thresholds of Significance For purposes of this analysis, the following thresholds are used to evaluate the significance of land use and planning impacts resulting from implementation of the proposed project: • Development resulting in physically dividing the surrounding community. • Development conflicting with the General Plan or Ordinance Code. Impact Evaluation Divide an Established Community Impact LAND-1: The proposed project would not physically divide an established community. Construction Impacts related to physical division of an established community are limited to operational impacts. No respective construction impacts would occur. Operation The physical division of an already established community typically refers to construction of a linear feature, such as an interstate, railroad tracks, or the removal of a means of access that would impact mobility within an established community and an outlying area. The proposed project would include the construction of 125 townhouse condominium units located in 19 three-story buildings, and associated amenities and landscaped open space, as well as 272 on-site parking spaces with available spaces along the street frontage. The proposed project would also involve the demolition Contra Costa County–Oak Road Townhouse Condominiums Project Land Use and Planning Draft EIR 3.10-16 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-10 Land Use.docx of all existing improvements currently on-site and associate with the former school. The development of the proposed townhouse condominium buildings would not impair access to any established community, impede travel or otherwise constitute division of an established community. Rather, the proposed project would establish connectivity and pedestrian access between Jones Road and Oak Road by providing private street and walkable landscaped open space. Impacts would be less than significant. Level of Significance Less than significant impact. Conflict with Applicable Land Use Plans, Policies, or Regulations Impact LAND-2: The proposed project would not cause a significant environmental impact due to conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect. Development of the proposed project would result in a significant impact if it would conflict with applicable land use plans and policies of the General Plan or the Ordinance Code that were adopted for the purpose of avoiding or mitigating an environmental effect. A policy inconsistency is considered a significant adverse impact only if the inconsistency would result in a significant adverse physical impact based on the established significance criterion. Consistency of the proposed project with applicable land use plans and policies is evaluated below. Consistency with the County’s adopted land use compatibility standards specifically with respect to noise are evaluated in Section 3.11, Noise; consistency with the County’s adopted Ordinance Code with respect to protected trees are evaluated in Section 3.3, Biological Resources. Construction Impacts related to consistency with applicable land use plans and policies are limited to operational impacts. No respective construction impacts would occur. Operation Contra Costa County General Plan Consistency The General Plan designates the project site as MH. The MH designation allows for densities between 22.0 and 29.9 multiple-family units per net acre. Primary land uses include attached single- family residences, multiple-family residences including condominiums, town houses, and apartments, as well as accessory buildings and structures ancillary to the primary uses. The proposed project would develop 125 townhouse condominiums, resulting in a total of 237,816 square feet of net new habitable construction on 5.94 acres or a net density of 26.3 dwelling unit per acre. Therefore, the density and use would be consistent with the General Plan land use designation and the proposed project would not require a General Plan Amendment. The proposed project would be consistent with the General Plan goals and policies relative to providing residences in unincorporated area of the County. Table 3.10-5 summarizes the proposed project’s consistency with the applicable policies of the General Plan adopted for various land use planning reasons, including the purpose of avoiding or mitigating an environmental impact.

A common outdoor use area that meets the goal can be provided as an alternative. Policy 11-4 Title 24, Part 2, of the California Code of Regulations requires that new multiple-family housing projects, hotels, and motels exposed to a Ldn of 60 dB or greater have a detailed acoustical analysis describing how the project will provide an interior Ldn of 45 dB or less. The County also shall require new single-family housing projects to provide for an interior Ldn of 45 dB or less. Consistent: Refer to Section 3.11, Noise, for further discussion. Policy 11-5 In developing residential areas exposed to a Ldn in excess of 65 dB due to single events such as train operation, indoor noise levels due to these single events shall not exceed a maximum A-weighted noise level of 50 dB in bedrooms and 55 dB in other habitable rooms. Single event indoor residential noise levels from airport related causes will be 45 dB CNEL. Consistent: Refer to Section 3.11, Noise, for further discussion. Contra Costa County Zoning Code Consistency The project site is currently zoned R-15, M-17, and M-29. The project applicant has proposed rezoning the entire site to P-1. As stated in Chapter 84-66.204, the intent of the P-1 district is to allow “diversification in the relationship of various uses, buildings, structures, lot sizes and open space while insuring (sic) substantial compliance with the General Plan and the intent of the County Code in requiring adequate standards necessary to satisfy the requirements of the public health, safety and general welfare. These standards shall be observed without unduly inhibiting the advantages of large-scale or special area planning.”9 The P-1 zoning would allow flexibility with respect to use, building types, lot size, and open space while ensuring the proposed project complies with the General Plan and requirements as set forth in the Ordinance Code. It also allows necessary public health and safety standards to be observed without inhibiting large-scale development. 9 Contra Costa County. 2018.

In the absence of the rezone, the proposed project could not advance. When the proposed project itself entails an amendment to the zoning ordinance, inconsistency with the existing designation is an element of the project itself, which then necessitates a legislative policy decision by the lead agency and does not signify a potential environmental effect. Impacts would be less than significant. Parking Based on the County parking standards, the proposed project is required to provide 250 residential parking spaces and 32 guest parking spaces, totaling 282 parking spaces. The proposed project would provide 300 parking spaces (272 on-site and 28 spaces available along street frontage). Bicycle Parking There are no designated bicycle lanes proposed as part of the proposed project, and no bicycle circulation would be available on-site. However, the proposed project would be consistent with Ordinance Code Section 82-16.412, which sets forth the amounts of bicycle parking that a project must provide. According to the Ordinance Code, long-term bicycle parking is not required for multi- family dwelling with private garage. The short-term bicycle parking requirement for multi-family dwelling with private garage is spaces for 5 percent of the number of bedrooms or two spaces (whichever is greater).10 Therefore, the proposed project would be required to and would provide 23 short-term bicycle parking spaces. Overall, the proposed project would not conflict with applicable land use plans, policies, or regulations of the General Plan or the Ordinance Code that were adopted for the purpose of avoiding or mitigating an environmental effect. Therefore, impacts would be less than significant. Level of Significance Less than significant impact. Cumulative Impacts The geographic scope of the cumulative land use analysis is the unincorporated area of Contra Costa County with a focus on the area surrounding the project site. Land use decisions for both the proposed project and for some of the other cumulative projects listed in Table 3-1 are made at the County level. Some of the projects listed in Table 3-1 are located in the cities of Walnut Creek and Pleasant Hill, and land use decisions for those projects are made at the city level. Development within the unincorporated County is governed by the General Plan and the Ordinance Code, which ensure logical and orderly development and require discretionary review to ensure that projects do not result in environmental impacts due to inconsistency with the General Plan and other land use planning regulations. This would minimize any cumulative impact related to division of an established community. 10 Contra Costa County Ordinance Code. 2018. Chapter 82-16.412—Bicycle Parking.

This noise impact analysis is based on the noise analyses prepared by Salter Inc., dated January 29, 2021, and May 7, 2021. These reports are contained in Appendix H of this document. During the Notice of Preparation (NOP) comment period, the following comments were received related to the proposed project regarding Noise: • Concerns regarding increased noise due to the proposed project. • Demolition, construction, and occupation would result in unacceptable noise pollution (residents were able to hear daily noise from the former Palmer School). • Noise would have negative impact on those working from home and home-bound resident. • Noise would reduce property values of adjacent properties. • The proposed project would exacerbate current noise issues at the Treat Boulevard intersection. • Inquiry about compensation for home-bound residents who would be impacted by construction noise. • The proposed project would result in noise, impacting adjacent residents’ well-being. • The roof decks could lead to noise concerns. • The 15-foot setback is a concern for neighboring residents due to noise concerns. • Concerns about noise and its impact on families and infants at adjacent properties. 3.11.2 - Environmental Setting Characteristics of Noise Noise is generally defined as unwanted or objectionable sound. Sound becomes unwanted when it interferes with normal activities, when it causes actual physical harm, or when it has adverse effects on health. The effects of noise on people can include general annoyance, interference with speech communication, sleep disturbance, and, in the extreme, hearing impairment. Noise effects can be caused by pitch or loudness. Pitch is the number of complete vibrations or cycles per second of a wave that result in the range of tone from high to low; higher-pitched sounds are louder to humans than lower-pitched sounds. Loudness is the intensity or amplitude of sound. Sound is produced by the vibration of sound pressure waves in the air. Sound pressure levels are used to measure the intensity of sound and are described in terms of decibels. The decibel (dB) is a logarithmic unit, which expresses the ratio of the sound pressure level being measured to a standard reference level. The 0 point on the dB scale is based on the lowest sound level that the healthy, Contra Costa County–Oak Road Townhouse Condominiums Project Noise Draft EIR 3.11-2 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx unimpaired human ear can detect. Changes of 3 dB or less are only perceptible in laboratory environments. Audible increases in noise levels generally refer to a change of 3 dB or more, as this level has been found to be barely perceptible to the human ear in outdoor environments. Only audible changes in existing ambient or background noise levels are considered potentially significant. The human ear is not equally sensitive to all frequencies within the audible sound spectrum, so sound pressure level measurements can be weighted to better represent frequency-based sensitivity of average healthy human hearing. One such specific “filtering” of sound is called “A-weighting.” A- weighted decibels (dBA) approximate the subjective response of the human ear to a broad frequency noise source by discriminating against very low and very high frequencies of the audible spectrum. They are adjusted to reflect only those frequencies that are audible to the human ear. Because decibels are logarithmic units, they cannot be added or subtracted by ordinary arithmetic means. For example, if one noise source produces a noise level of 70 dB, the addition of another noise source with the same noise level would not produce 140 dB; rather, they would combine to produce a noise level of 73 dB. Noise Descriptors There are many ways to rate noise for various intervals, but an appropriate rating of ambient noise affecting humans also accounts for the annoying effects of sound. Equivalent continuous sound level (Leq) is the total sound energy of time-varying noise over a sample period. However, the predominant rating scales for human communities in the State of California are the Leq and community noise equivalent level (CNEL) or the day-night average level (DNL) based on dBA. CNEL is the time-varying noise over a 24-hour period, with a 5 dBA weighting factor applied to the hourly Leq for noises occurring from 7:00 p.m. to 10:00 p.m. (defined as relaxation hours) and a 10 dBA weighting factor applied to noise occurring from 10:00 p.m. to 7:00 a.m. (defined as sleeping hours). DNL is similar to the CNEL scale but without the adjustment for events occurring during the evening hours. CNEL and DNL are within one dBA of each other and are normally exchangeable. The noise adjustments are added to the noise events occurring during the more sensitive hours. Other noise rating scales of importance when assessing the annoyance factor include the maximum noise level (Lmax), which is the highest exponential time-averaged sound level that occurs during a stated time period. The noise environments discussed in this analysis are specified in terms of maximum levels denoted by Lmax for short-term noise impacts. Lmax reflects peak operating conditions and addresses the annoying aspects of intermittent noise. Noise Propagation From the noise source to the receiver, noise changes both in level and frequency spectrum. The most obvious is the decrease in noise as the distance from the source increases. The manner in which noise reduces with distance depends on whether the source is a point or line source, as well as ground absorption, atmospheric conditions (wind, temperature gradients, and humidity) and refraction, and shielding by natural and manmade features. Sound from point sources, such as an air conditioning condenser, a piece of construction equipment, or an idling truck, radiates uniformly outward as it travels away from the source in a spherical pattern. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Noise FirstCarbon Solutions 3.11-3 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx The attenuation or sound drop-off rate is dependent on the conditions of the land between the noise source and receiver. To account for this ground-effect attenuation (absorption), two types of site conditions are commonly used in noise models: soft-site and hard-site conditions. Soft-site conditions account for the sound propagation loss over natural surfaces such as normal earth and ground vegetation. For point sources, a drop-off rate of 7.5 dBA per each doubling of the distance (dBA/DD) is typically observed over soft ground with landscaping, as compared with a 6 dBA/DD drop-off rate over hard ground such as asphalt, concrete, stone, and very hard packed earth. For line sources, such as traffic noise on a roadway, a 4.5 dBA/DD is typically observed for soft-site conditions compared to the 3 dBA/DD drop-off rate for hard-site conditions. Table 3.11-1 briefly defines these measurement descriptors and other sound terminology used in this section. Table 3.11-1: Sound Terminology Term Definition Sound A vibratory disturbance created by a vibrating object which, when transmitted by pressure waves through a medium such as air, can be detected by a receiving mechanism such as the human ear or a microphone. Noise Sound that is loud, unpleasant, unexpected, or otherwise undesirable. Ambient Noise The composite of noise from all sources near and far in a given environment. Decibel (dB) A unitless measure of sound on a logarithmic scale, which represents the squared ratio of sound pressure amplitude to a reference sound pressure. The reference pressure is 20 micropascals, representing the threshold of human hearing (0 dB). A-Weighted Decibel (dBA) An overall frequency-weighted sound level that approximates the frequency response of the human ear. Equivalent Noise Level (Leq) The average sound energy occurring over a specified time period. In effect, Leq is the steady-state sound level that in a stated period would contain the same acoustical energy as the time-varying sound that actually occurs during the same period. Maximum and Minimum Noise Levels (Lmax and Lmin) The maximum or minimum instantaneous sound level measured during a measurement period. Day-Night Level (DNL or Ldn) The energy average of the A-weighted sound levels occurring during a 24-hour period, with 10 dB added to the A-weighted sound levels occurring between 10 p.m. and 7 a.m. (nighttime). Community Noise Equivalent Level (CNEL) The energy average of the A-weighted sound levels occurring during a 24-hour period, with 5 dB added to the A-weighted sound levels occurring between 7 p.m. and 10 p.m. and 10 dB added to the A-weighted sound levels occurring between 10 p.m. and 7 a.m. Source: Data compiled by FCS 2021.

Generally, the loudness of traffic noise is increased by heavier traffic volumes, higher speeds, and greater number of trucks. Vehicle noise is a combination of the noise produced by the engine, exhaust, and tires. Because of the logarithmic nature of noise levels, a doubling of the traffic volume (assuming that the speed and truck mix do not change) results in a noise level increase of 3 dBA. Based on the Federal Highway Administration (FHWA) community noise assessment criteria, this change is “barely perceptible”; for reference, a doubling of perceived noise levels would require an increase of approximately 10 dBA. The truck mix on a given roadway also has an effect on community noise levels. As the number of heavy trucks increases and becomes a larger percentage of the vehicle mix, adjacent noise levels increase. Stationary Noise A stationary noise producer is any entity in a fixed location that emits noise. Examples of stationary noise sources include machinery, engines, energy production, and other mechanical or powered equipment and activities such as loading and unloading or public assembly that may occur at commercial, industrial, manufacturing, or institutional facilities. Furthermore, while noise generated by the use of motor vehicles over public roads is preempted from local regulation, although the use of these vehicles is considered a stationary noise source when operated on private property such as at a construction site, a truck terminal, or warehousing facility. The emitted noise from the producer can be mitigated to acceptable levels either at the source or on the adjacent property through the use of proper planning, setbacks, block walls, acoustic-rated windows, dense landscaping, or by changing the location of the noise producer. The effects of stationary noise depend on factors such as characteristics of the equipment and operations, distance and pathway between the generator and receptor, and weather. Stationary noise sources may be regulated at the point of manufacture (e.g., equipment or engines), with limitations on the hours of operation, or with provision of intervening structures, barriers, or topography. Construction activities are a common source of stationary noise. Construction-period noise levels are higher than background ambient noise levels but eventually cease once construction is complete. Construction is performed in discrete steps, each of which has its own mix of equipment and, consequently, its own noise characteristics. These various sequential phases would change the character of the noise generated on each construction site and, therefore, would change the noise levels as construction progresses. Despite the variety in the type and size of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction-related noise ranges to be categorized by work phase. Table 3.11-2 shows typical noise levels of construction equipment as measured at a distance of 50 feet from the operating equipment.

Highway Construction Noise Handbook. August. Noise from Multiple Sources Because sound pressure levels in decibels are based on a logarithmic scale, they cannot be added or subtracted in the usual arithmetical way. Therefore, sound pressure levels in decibels are logarithmically added on an energy summation basis. In other words, adding a new noise source to an existing noise source, both producing noise at the same level, will not double the noise level. Instead, if the difference between two noise sources is 10 dBA or more, the louder noise source will dominate, and the resultant noise level will be equal to the noise level of the louder source. In general, if the difference between two noise sources is 0–1 dBA, the resultant noise level will be 3 dBA higher than the louder noise source, or both sources if they are equal. If the difference between two noise sources is 2–3 dBA, the resultant noise level will be 2 dBA above the louder noise source. If the difference between two noise sources is 4–10 dBA, the resultant noise level will be 1 dBA higher than the louder noise source.

The effects of groundborne vibration typically only causes a nuisance to people, but in extreme cases, excessive groundborne vibration has the potential to cause structural damage to buildings. Although groundborne vibration can be felt outdoors, it is typically only an annoyance to people indoors where the associated effects of the shaking of a building can be notable. Groundborne noise is an effect of groundborne vibration and only exists indoors, since it is produced from noise radiated from the motion of the walls and floors of a room, and may also consist of the rattling of windows or dishes on shelves. Several different methods are used to quantify vibration amplitude such as the maximum instantaneous peak in the vibrations velocity, which is known as the peak particle velocity (PPV) or the root mean square (rms) amplitude of the vibration velocity. Because of the typically small amplitudes of vibrations, vibration velocity is often expressed in decibels—denoted as LV—and is based on the reference quantity of 1 micro-inch per second. To distinguish vibration levels from noise levels, the unit is written as “VdB.” Although groundborne vibration can be felt outdoors, it is typically only an annoyance to people indoors where the associated effects of the shaking of a building can be notable. When assessing annoyance from groundborne vibration, vibration is typically expressed as rms velocity in units of decibels of 1 micro-inch per second, with the unit written in VdB. Typically, developed areas are continuously affected by vibration velocities of 50 VdB or lower. Human perception to vibration starts at levels as low as 67 VdB. Annoyance due to vibration in residential settings starts at approximately 70 VdB. Off-site sources that may produce perceptible vibrations are usually caused by construction equipment, steel-wheeled trains, and traffic on rough roads, while smooth roads rarely produce perceptible groundborne noise or vibration. Construction activities, such as blasting, pile driving and operating heavy earthmoving equipment, are common sources of groundborne vibration. Construction vibration impacts on building structures are generally assessed in terms of PPV. Typical vibration source levels from construction equipment are shown in Table 3.11-3.1 Table 3.11-3: Vibration Levels of Construction Equipment Construction Equipment PPV at 25 Feet (inches/second) rms Velocity in Decibels (VdB) at 25 Feet Water Trucks 0.001 57 Scraper 0.002 58 Bulldozer—Small 0.003 58 Jackhammer 0.035 79 Concrete Mixer 0.046 81 1 Federal Highway Administration (FHWA). 2006.

The propagation of groundborne vibration is not as simple to model as airborne noise. This is because noise in the air travels through a relatively uniform medium, while groundborne vibrations travel through the earth, which may contain significant geological differences. Factors that influence groundborne vibration include: • Vibration source: Type of activity or equipment, such as impact or mobile, and depth of vibration source; • Vibration path: Soil type, rock layers, soil layering, depth to water table, and frost depth; and • Vibration receiver: Foundation type, building construction, and acoustical absorption. Among these factors that influence groundborne vibration, there are significant differences in the vibration characteristics when the source is underground compared to at the ground surface. In addition, soil conditions are known to have a strong influence on the levels of groundborne vibration. Among the most important factors are the stiffness and internal damping of the soil and the depth to bedrock. Vibration propagation is more efficient in stiff clay soils than in loose sandy Contra Costa County–Oak Road Townhouse Condominiums Project Noise Draft EIR 3.11-8 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx soils, and shallow rock seems to concentrate the vibration energy close to the surface, and can result in groundborne vibration problems at large distance from the source. Factors such as layering of the soil and depth to the water table can have significant effects on the propagation of groundborne vibration. Soft, loose, sandy soils tend to attenuate more vibration energy than hard, rocky materials. Vibration propagation through groundwater is more efficient than through sandy soils. There are three main types of vibration propagation: surface, compression, and shear waves. Surface waves, or Rayleigh waves, travel along the ground’s surface. These waves carry most of their energy along an expanding circular wave front, similar to ripples produced by throwing a rock into a pool of water. P- waves, or compression waves, are body waves that carry their energy along an expanding spherical wave front. The particle motion in these waves is longitudinal (i.e., in a “push-pull” fashion). P-waves are analogous to airborne sound waves. S-waves, or shear waves, are also body waves that carry energy along an expanding spherical wave front. However, unlike P-waves, the particle motion is transverse, or side-to-side and perpendicular to the direction of propagation. As vibration waves propagate from a source, the vibration energy decreases in a logarithmic nature and the vibration levels typically decrease by 6 VdB per doubling of the distance from the vibration source. As stated above, this drop-off rate can vary greatly depending on the soil type, but it has been shown to be effective enough for screening purposes, in order to identify potential vibration impacts that may need to be studied through actual field tests. The vibration level (calculated below as “PPV”) at a distance from a point source can generally be calculated using the vibration reference equation: PPV= PPVref * (25/D)^n (in/sec) Where: PPVref = reference measurement at 25 feet from vibration source D = distance from equipment to the receptor n = vibration attenuation rate through ground According to Chapter 12 of the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment manual, an “n” value of 1.5 is recommended to calculate vibration propagation through typical soil conditions.2 Existing Noise Levels Ambient Noise The proposed project site is located within unincorporated Contra Costa County, California, adjacent to the City of Walnut Creek city limits. Surrounding the project site are apartments uses to the north, single-family residences east across Oak Road, apartment buildings to the south, Jones Road, Bay Area Rapid Transit (BART), and Interstate 680 (I-680) to the west. The dominant noise source in the project vicinity is noise from traffic on local roadways and trains, primarily from traffic Oak Road, Jones Road, BART, and I-680. 2 Federal Transit Administration (FTA). 2006.

The long-term modeling results show that environmental noise levels range up to approximately 68 dBA CNEL at 40 feet west of the Oak Road centerline and 12 feet above grade, 60 dBA CNEL at 210 feet west of the Oak Road centerline and 12 feet above grade, and 65 dBA CNEL at 35 feet east of the Jones Road centerline. The short-term modeling results show that environmental noise levels range 66 dBA CNEL 50 feet west of Oak Road and 5 feet above grade, and 66/67 dBA CNEL at 35 feet east of the Jones Road centerline and 5 feet/16 feet above grade. In addition, instantaneous noise levels from BART passbys were approximately 80 Lmax30 80 dB4. Noise-Sensitive Land Uses Noise-sensitive land uses generally consist of those uses where exposure to noise would result in adverse effects, as well as uses for which quiet is an essential element of their intended purpose. Residential dwellings are of primary concern, because of the potential for increased and prolonged exposure of individuals to both interior and exterior noise levels. Other typical noise-sensitive land uses include hospitals, convalescent facilities, hotels, religious institutions, libraries, and other uses where low noise levels are essential. 3.11.3 - Regulatory Framework Federal Noise Control Act The adverse impact of noise was officially recognized by the federal government in the Noise Control Act of 1972, which serves three purposes: • Promulgating noise emission standards for interstate commerce. • Assisting State and local abatement efforts. • Promoting noise education and research. The Federal Office of Noise Abatement and Control (ONAC) was initially tasked with implementing the Noise Control Act. However, the ONAC has since been eliminated, leaving the development of federal noise policies and programs to other federal agencies and interagency committees. Among the agencies now regulating noise are the Occupational Safety and Health Administration (OSHA), which limits noise exposure of workers to 90 dB Leq or less for 8 continuous hours or 105 dB Leq or less for 1 continuous hour; the United States Department of Transportation (USDOT), which assumed a significant role in noise control through its various operating agencies; and the Federal Aviation Administration (FAA), which regulates noise of aircraft and airports. Surface transportation system noise is regulated by a host of agencies, including the FTA. Transit noise is regulated by the federal Urban Mass Transit Administration, while freeways that are part of the interstate highway system are regulated by the FHWA. Finally, the federal government actively advocates that local jurisdictions use their land use regulatory authority to arrange new development in such a way that “noise sensitive” uses are either prohibited from being sited adjacent to a highway, or alternatively, that developments are planned and constructed in such a manner that minimize potential noise impacts.

State California General Plan Guidelines Established in 1973, the California Department of Health Services Office of Noise Control was instrumental in developing regularity tools to control and abate noise for use by local agencies. One significant model is the “Land Use Compatibility for Community Noise Environments Matrix,” which allows the local jurisdiction to delineate compatibility of sensitive uses with various incremental levels of noise.4 Government Code Section 65302 mandates that the legislative body of each county and city in California adopt a noise element as part of its comprehensive general plan. The local noise element must recognize the land use compatibility guidelines published by the State Department of Health Services. The guidelines rank noise/land use compatibility in terms of normally acceptable, conditionally acceptable, normally unacceptable, and clearly unacceptable. The proposed project is also subject to review under the California Environmental Quality Act (CEQA).

These requirements are provided in the 2016 California Building Standards Code (CBC) (California Code of Regulations [CCR] Title 24).5 As provided in the CBC, the noise insulation standards set forth an interior standard of 45 dBA CNEL as measured from within the structure’s interior. When such structures are located within a 65-dBA CNEL (or greater) exterior noise contour associated with a traffic noise along a roadway, an acoustical analysis is required to ensure that interior levels do not exceed the 45 dBA CNEL threshold. Title 24 standards are typically enforced by local jurisdictions through the building permit application process. Local Contra Costa County General Plan Noise Element Policy 11-1 of the Noise Element of the 2005-2020 Contra Costa County General Plan (General Plan)6 provides Noise and Land Use Compatibility Guidelines for new multi-family residential projects. According to these guidelines, 60 dBA or less is considered “normally acceptable,” 55 to 70 dBA is considered “conditionally acceptable,” 70 to 75 dBA is considered “normally unacceptable,” and 75 dBA and above is considered “unacceptable.” The other applicable sections of the Noise Element of the General Plan are listed below. Policy 11-2 The standard for outdoor noise levels in residential areas is an DNL of 60 dB. However, an DNL of 60 dB or less may not be achievable in all residential areas due to economic or aesthetic constraints. One example is small balconies associated with multi-family housing. In this case, second and third story balconies may be difficult to control to the goal. A common outdoor use area that meets the goal can be provided as an alternative. Policy 11-3 If the primary noise source is train passbys, then the standard for outdoor noise levels in residential areas is an DNL of 70 dB. A higher DNL is allowable since the DNL is controlled by a relatively few number of train passbys that are disruptive outdoors only for short periods. Even though the DNL may be high, during the majority of the time the noise level will be acceptable. Policy 11-4 Title 24, Part 2, of the California Code of Regulations requires that new multiple family housing projects, hotels, and motels exposed to a DNL of 60 dB or greater have a detailed acoustical analysis describing how the project will provide an interior DNL of 45 dB or less. The County also shall require new single-family housing projects to provide for an interior DNL of 45 dB or less. 5 California Building Standards Commission. 2017.

City of Walnut Creek General Plan Safety and Noise Element The Safety and Noise Element of the Walnut Creek General Plan 7 establishes land use compatibility standards for noise. The land use compatibility standards for noise provide the basis for making decisions on location of land uses in relation to noise sources and for determining noise mitigation requirements. According to the City of Walnut Creek’s Land Use/Noise Compatibility standards, exterior noise levels up to 65 dBA DNL are considered normally acceptable for new multi-family residential land use developments, conditionally acceptable from 65 dBA to 75 dBA DNL, and unacceptable above 75 dBA DNL. The City of Walnut Creek has adopted the following General Plan Safety and Noise Element goals, policies, and actions to reduce potential noise hazards. Goal 8 Provide compatible noise environments for new development, redevelopment, and condominium conversions. Policies Policy 8.1 Apply the noise and land use compatibility table and standards to all residential, commercial, and mixed-use proposals, including condominium conversions. Policy 8.2 Address the issue of residences affected by intermittent urban noise from sources such as heating, ventilating, and air conditioning equipment and by outdoor maintenance activities, such as parking lot sweeping and early morning garbage collection. Action 8.2.2 For new multi-family residential projects and for the residential component of mixed-use development, use a standard of 65 DNL in outdoor areas, excluding balconies. Action 8.2.3 Strive for a maximum interior noise levels at 45 DNL in all new residential units. 7 City of Walnut Creek. 2006. Walnut Creek General Plan, Safety and Noise Element. April 4.

Contra Costa County Municipal Code–Noise Ordinance It should be noted that the Contra Costa County Ordinance Code does not contain any noise ordinance codes or performance standards that are applicable to the project. City of Walnut Creek Municipal Code–Noise Ordinance The City of Walnut Creek Noise Ordinance is codified in Chapter 6, Article 2 of the City’s Municipal Code. Section 4-6.203f prohibits construction activities other than between the hours of 7:00 a.m. and 6:00 p.m. on non-holiday weekdays, or those precise hours of operation enumerated in individual building and grading permits. 3.11.4 - Methodology The noise environment at the project site is influenced by vehicle traffic on Oak Road, Jones Road, and Interstate I-680, as well as from BART trains on the adjacent tracks. To help quantify environmental noise levels, a monitor continuously measured noise levels at the site between December 7 and 11, 2020. Two short-term measurements were conducted to help determine how noise levels vary with location and elevation. In addition to determining average environmental noise levels, typical maximum instantaneous noise levels from BART passbys were measured at the monitoring location closest to the BART. Assuming a traffic volume increase of 3 percent per year, 1 dB was added to account for future traffic volume increases. 3.11.5 - Impacts and Mitigation Measures Significance Criteria According to Appendix G, Environmental Checklist, of the CEQA Guidelines, to determine whether impacts related to noise and vibration are significant environmental effects, the following questions are analyzed and evaluated. It should be noted that the significance criteria question (a), below, is from the Land Use and Planning section of the CEQA Guidelines Appendix G checklist questions. However, this question addresses impacts related to conflicts with land use plans, which would include project-related conflicts to the noise land use compatibility standards of the Noise Element of the General Plan. Therefore, these impacts are addressed here. a) Cause a significant environmental impact due to a conflict with a land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect?8 8 This significance criteria question is from the Land Use and Planning section of the CEQA Guidelines Appendix G checklist questions. However, since the question addresses impacts related to conflicts with land use plans, which would include project-related conflicts related to noise land use compatibility standards of the General Plan Noise Element, it is also included here.

Specific Thresholds of Significance For purposes of this analysis, the following thresholds are used to evaluate the significance of noise and vibration resulting from implementation of the proposed project. • A significant impact would occur if the proposed project would conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect . For new industrial land use developments, ambient noise levels up to 75 dBA DNL are considered “normally acceptable.” • A significant impact would occur if the proposed project would generate a substantial temporary or permanent increase in ambient noise levels in the project vicinity in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies. - For temporary construction noise, a significant impact would occur if construction activities would result in a substantial temporary increase in ambient noise levels that would result in annoyance or sleep disturbance of sensitive receptors or if project-related construction grading activities would generate noise during hours other than those established as permissible in Article 716-8.1004 in the County’s Code of Ordinances. - For project-related traffic noise, a significant impact would occur if the proposed project would cause the DNL to increase by 5 dBA or more even if the DNL would remain below normally acceptable levels for a receiving land use (as defined in the land use compatibility standards); or by 3 dBA or more, thereby causing the DNL in the project vicinity to exceed normally acceptable levels and result in noise levels that would be considered conditionally acceptable for a receiving land use; or by 1.5 dBA or more where the DNL currently exceeds conditionally acceptable levels. A doubling of traffic volume generally results in a 3 dBA increase in noise. - For project-related stationary noise sources, Contra Costa County established a maximum exterior noise performance threshold for receiving residential land uses of 65 dBA DNL. Contra Costa County also established a maximum interior noise threshold of 45 dBA DNL; however, if ambient noise levels exceed 65 dBA DNL due to train noise, the maximum interior noise threshold would be 50 dBA DNL in bedrooms and 55 dBA DNL in other habitable rooms. For purposes of this analysis, an increase of more than 3 dBA above the applicable noise performance thresholds would be considered a significant impact. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Noise FirstCarbon Solutions 3.11-15 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx • A significant impact would occur if the proposed project would generate groundborne vibration or groundborne noise levels in excess of applicable standards. Contra Costa County has not adopted criteria for construction or operational groundborne vibration impacts. Therefore, for purposes of this analysis, the FTA’s construction vibration impact criteria are utilized. The FTA threshold of 0.2 in/sec PPV is the potential damage criteria threshold for buildings of non-engineered timber and masonry construction. For operational impacts, a significant impact will occur if project ongoing activities would produce groundborne vibrations that are perceptible without instruments by a reasonable person at the property lines of the site. • For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport, a significant impact would occur if the proposed project would expose people residing or working in the project area to excessive noise levels. Impact Evaluation Noise Levels That Would Conflict with Any Land Use Plan, Policy, or Regulation Impact NOI-1: The proposed project could cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect. A significant impact would occur if the project would result in a conflict with Contra Costa County or the City of Walnut Creek applicable adopted land use compatibility standards. The applicable standards are as follows: • 60 dBA DNL for the proposed multi-family residential land use development; or • conditionally acceptable land use compatibility threshold of 70 dBA DNL for the proposed multi-family residential land use development. Contra Costa County and the City of Walnut Creek also establish a maximum interior noise threshold of 45 dBA DNL; however, for new downtown mixed-use development or for new residential development affected by noise from BART or helicopters, the project must ensure that maximum indoor noise levels do not exceed 50 DNL in bedrooms and 55 DNL in other rooms and an alternate outdoor noise goal do not exceed 70 dBA DNL. Estimated future noise levels at future façades range from 60 dBA DNL at interior shielded portions of the site to approximately 74 dBA DNL at elevated locations nearest the BART tracks and I-680. This falls into the County’s normally acceptable to normally unacceptable land use compatibility categories for multi-family residences. Therefore, exterior building assemblies will need to be sound rated to reduce transportation noise to acceptable levels. According to the noise study prepared by Salter Inc., window and exterior door assemblies of units located within 175-feet of the centerline of Jones Road will need to have Sound Transmission Class (STC) ratings of STC 39 to reduce project traffic noise levels to meet the interior noise level standards; while units located within 100 feet of the centerline of Oak Road will need to have ratings Contra Costa County–Oak Road Townhouse Condominiums Project Noise Draft EIR 3.11-16 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx of STC 34 to reduce project traffic noise levels to meet the interior noise level standards. For reference, typical construction grade dual-pane windows achieve sound insulation ratings of approximately STC 28. Ventilation systems must not compromise sound insulation of the exterior wall assemblies. Where windows will need to be closed to meet the interior noise criterion, an alternate means of providing outside air to habitable spaces should be provided. The ventilation systems will need to maintain the exterior-to-interior noise reduction of the overall façade. The analysis also analyzed potential impacts to proposed outdoor active use areas. The analysis determined that proposed outdoor active use areas, which are interior to the site, will not be exposed to traffic noise levels in excess of established standards. Therefore, due to existing traffic noise levels in the project vicinity, implementation of the project could expose the proposed residential land uses to noise levels that would conflict with the County’s established noise land use compatibility standards adopted for the purpose of avoiding or mitigating an environmental effect. However, with implementation of Mitigation Measure (MM) NOI-1, this impact would be reduced to less than significant. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures MM NOI-1 Implement Traffic Noise-reduction Measures To reduce potential traffic noise impacts, the following multi-part mitigation measure shall be implemented for the proposed project: • The project applicant shall ensure inclusion of ventilation systems that would permit windows to remain closed for prolonged periods. The systems must not compromise sound insulation of the exterior wall assemblies. • Prior to issuance of building permits, the project applicant shall provide design plans which show that window and exterior door assemblies of units located within 175-feet of the centerline of Jones Road will have ratings of Sound Transmission Class (STC ) 39 to reduce project traffic noise levels to meet the interior noise level standards. Alternatively, the project applicant shall provide a design-level noise study that demonstrates the specific window and door assembly sound ratings to achieve the required interior noise threshold for each of these impacted residential units. • Prior to issuance of building permits, the project applicant shall provide design plans which show that window and exterior door assemblies of units located within 100-feet of the centerline of Oak Road will have ratings of STC 34 to reduce project traffic noise levels to meet the interior noise level standards. Alternatively, the project applicant shall provide a design-level noise study that demonstrates the specific window and door assembly sound ratings to achieve the required interior noise threshold for each of these impacted residential units.

Substantial Noise Increase in Excess of Standards Impact NOI-2: The proposed project could generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies. Construction For purposes of this analysis, for temporary construction noise, a significant impact would occur if construction activities would result in a substantial temporary increase in ambient noise levels that would result in annoyance or sleep disturbance of sensitive receptors or if project-related construction grading activities would generate noise during hours other than those established as permissible in Article 716-8.1004 in the County’s Code of Ordinances. Noise impacts from construction activities associated with the project would be a function of the noise generated by construction traffic, construction equipment, equipment location, sensitivity of nearby land uses, and the timing and duration of the construction activities. A discussion of the potential impacts associated with each of these types of activities is provided below. Construction Traffic Noise One type of noise impact that could occur during project construction would result from the increase in traffic flow on local streets, associated with the transport of workers, equipment, and materials to and from the project site. The transport of workers and construction equipment and materials to the project site would incrementally increase noise levels on access roads leading to the site. Because project construction workers and construction equipment would use existing routes, noise from passing trucks would be similar to existing vehicle-generated noise on these local roadways. In addition, these trips would not result in a doubling of daily traffic volumes on any of the local roadways in the project vicinity and would thus not result in a perceptible change in existing traffic noise levels. For this reason, intermittent noise from construction trips would be minor when averaged over a longer time period and would not be expected to result in a perceptible increase in hourly- or average daily traffic noise levels in the project vicinity. Therefore, construction-related noise impacts associated with the transportation of workers and equipment to the project site would be less than significant. Construction Equipment Noise Construction is performed in discrete steps, each of which entails its own mix of equipment, and consequently, its own noise characteristics. These various sequential phases would change the character of the noise generated on-site. Thus, the noise levels vary as construction progresses. Despite the variety in the types and sizes of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction noise ranges to be categorized by work phase. Table 3.11-2 lists the maximum noise levels recommended for noise impact assessments for typical construction equipment based on a distance of 50 feet between the equipment and a noise receptor. Contra Costa County–Oak Road Townhouse Condominiums Project Noise Draft EIR 3.11-18 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx The site preparation phase, which includes excavation and grading activities, tends to generate the highest noise levels, because the noisiest construction equipment is earthmoving equipment. Earthmoving equipment includes excavating machinery and compacting equipment, such as bulldozers, draglines, backhoes, front loaders, roller compactors, scrapers, and graders. Typical operating cycles for these types of construction equipment may involve 1 or 2 minutes of full power operation followed by 3 or 4 minutes at lower power settings. Operating cycles for these types of construction equipment may involve 1 or 2 minutes of full power operation followed by 3 or 4 minutes at lower power settings. Construction of the proposed project is expected to require the use of scrapers, bulldozers, water trucks, haul trucks, and pickup trucks. The foundation would involve spread footings, so impact equipment such as pile drivers is not expected to be used during construction of the project. Based on the information provide in Table 3.11-2, the maximum noise level generated by each scraper is assumed to be 85 dBA Lmax at 50 feet from this equipment. Each bulldozer would generate 85 dBA Lmax at 50 feet. The maximum noise level generated by graders is approximately 85 dBA Lmax at 50 feet. Each doubling of sound sources with equal strength increases the noise level by 3 dBA. Assuming that each piece of construction equipment operates at some distance from the other equipment, a reasonable worst-case combined noise level during this phase of construction would be 90 dBA Lmax at a distance of 50 feet from the acoustic center of a construction area. This would result in a reasonable worst-case hourly average of 86 dBA Leq. The acoustic center reference is used, because construction equipment must operate at some distance from one another on a project site, and the combined noise level as measured at a point equidistant from the sources would (acoustic center) be the worst-case maximum noise level. The effect on sensitive receptors is evaluated below. The nearest off-site noise-sensitive receptor to the project site is the multi-family residence located southeast of the project building, which would be located approximately 70 feet from the acoustic center of construction activity where multiple pieces of heavy machinery would operate. Again, the acoustic center refers to a point equidistant from multiple pieces of equipment operating simultaneously which would produce the worst-case maximum noise level. At this distance, construction noise levels at the exterior façade of this nearest residential home would be expected to range up to approximately 87 dBA Lmax, with a worst-case hourly average of approximately 83 dBA Leq, intermittently, when multiple pieces of heavy construction equipment operate simultaneously at the nearest construction footprint. These noise levels would be intermittent and would be reduce as equipment moves over the project site further from adjacent sensitive receptors. Therefore, restricting construction activities to non-weekend, non-holiday daytime hours of 7:00 a.m. to 6:00 p.m. would ensure that construction noise would not result in a substantial exceedance of the construction noise standards established by General Plan Policy 11-8 and the Walnut Creek Municipal Code. MM NOI-2 requires adherence to the County’s permissible construction hours and also requires implementation of best management noise reduction techniques and practices that would ensure that construction noise levels would not result in a substantial temporary increase in ambient noise levels that would result in annoyance or sleep disturbance of nearby sensitive receptors. Therefore, with implementation of MM NOI-2, temporary construction noise impacts would be reduced to less than significant. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Noise FirstCarbon Solutions 3.11-19 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx Operation The proposed project would result in an increase in traffic on local roadway segments in the project vicinity. In addition, implementation of the project would introduce new stationary noise sources to the ambient noise environment in the project vicinity, including new mechanical ventilation equipment. The potential for a substantial increase in ambient noise levels resulting from these noise sources is analyzed below. Traffic Noise For project-related traffic noise, a significant impact would occur if the proposed project would cause the DNL to increase by 5 dBA or more even if the DNL would remain below normally acceptable levels for a receiving land use (as defined in the land use compatibility standards); or by 3 dBA or more, thereby causing the DNL in the project vicinity to exceed normally acceptable levels and result in noise levels that would be considered conditionally acceptable for a receiving land use; or by 1.5 dBA or more where the DNL currently exceeds conditionally acceptable levels. A doubling of traffic volume generally results in a 3 dBA increase in noise. The noise study prepared by Salter, Inc. identifies that vehicles will enter and exit the site via driveways on Jones Road and Oak Road. A traffic study was prepared for the project, titled Transportation Analysis for the Summerhill Homes Townhome Condo Site Residential Redevelopment at 2740 Jones Road in Walnut Creek, California, by Hexagon Transportation Consultants, Inc., and dated May 10, 2021. The traffic analysis includes existing and project- generated AM and PM peak-hour traffic volumes at four study intersections in the project vicinity. The intersections are Oak Road and Jones Road, Oak Road and Treat Boulevard, Jones Road and the project driveway, and Oak Road and the project driveway. The intersection volume data indicates that peak-hour traffic volumes will increase by 3 percent or less, which corresponds with less than a 1 dB increase in the traffic noise levels DNL. Therefore, project-related traffic noise level would result in less than significant increases in traffic noise levels along modeled roadway segments in the project vicinity. This would be a less than significant impact, and no mitigation would be required. Stationary Noise For project-related stationary noise sources, Contra Costa County established a maximum exterior noise performance threshold for receiving residential land uses of 65 dBA DNL. Contra Costa County also established a maximum interior noise threshold of 45 dBA DNL; however, if ambient noise levels exceed 65 dBA DNL due to train noise, the maximum interior noise threshold would be 50 dBA DNL in bedrooms and 55 dBA DNL in other habitable rooms. For purposes of this analysis, an increase of more than 3 dBA above the applicable noise performance thresholds would be considered a significant impact. Implementation of the project would introduce new stationary noise sources to the ambient noise environment in the project vicinity, including new mechanical ventilation equipment. The project would include installation of new rooftop mechanical ventilation equipment. Proposed parking areas would be enclosed in parking structures, and associated noise would not propagate to nearby sensitive receptors; thus, the following analysis is limited to stationary noise associated with proposed mechanical equipment. Contra Costa County–Oak Road Townhouse Condominiums Project Noise Draft EIR 3.11-20 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx Noise levels from typical mechanical ventilation equipment range up to approximately 60 dBA Leq as measured at a distance of 25 feet. The building’s proposed mechanical ventilation units could be located as close as 30 feet from the nearest noise-sensitive receptor, which is the multi-family residential home located south of the proposed building. At this distance, noise levels generated by this equipment would attenuate to below 58.5 dBA Leq at this closest residential receptor. These noise levels would not exceed Contra Costa County’s or the City of Walnut Creek’s maximum exterior noise threshold for receiving residential land uses of 65 dBA DNL. They would therefore also not exceed the maximum interior noise threshold of 45 dBA DNL as measured inside the nearest residential receptor. Therefore, operational noise levels generated by the proposed mechanical ventilation equipment would not result in a substantial permanent increase in ambient noise levels in excess of any of the noise performance thresholds, and would represent a less than significant impact. Level of Significance Before Mitigation Potentially significant impact (construction noise only). Mitigation Measures MM NOI-2 Implement Noise-reduction Measures During Construction To reduce potential construction noise impacts, the following multi-part mitigation measure shall be implemented for the proposed project: • The construction contractor shall ensure that all equipment driven by internal combustion engines shall be equipped with mufflers, which are in good condition and appropriate for the equipment. • The construction contractor shall ensure that unnecessary idling of internal combustion engines (i.e., idling in excess of 5 minutes) is prohibited. • The construction contractor shall utilize “quiet” models of air compressors and other stationary noise sources where technology exists. • At all times during project grading and construction, the construction contractor shall ensure that stationary noise-generating equipment shall be located as far as practicable from sensitive receptors and placed so that emitted noise is directed away from adjacent residences. • The construction contractor shall ensure that the construction staging areas shall be located to create the greatest feasible distance between the staging area and noise-sensitive receptors nearest the project site. • The construction contractor shall control noise from construction workers' radios to a point where they are not audible at existing residences bordering the project site. • The construction contractor shall designate a "disturbance coordinator" who would be responsible for responding to any complaints about construction noise. The disturbance coordinator will determine the cause of the noise complaint (e.g., bad muffler, etc.) and will require that reasonable measures be implemented to correct the problem.

Level of Significance After Mitigation Less than significant impact. Groundborne Vibration/Noise Levels Impact NOI-3: The proposed project would not result in generation of excessive groundborne vibration or groundborne noise levels. A significant impact would occur if the proposed project would generate groundborne vibration or groundborne noise levels in excess of applicable standards. Contra Costa County has not adopted criteria for construction or operational groundborne vibration impacts. Therefore, for purposes of this analysis, the FTA’s construction vibration impact criteria are utilized. The FTA threshold of 0.2 in/sec PPV is the potential damage criteria threshold for buildings of non-engineered timber and masonry construction. For operational impacts, a significant impact will occur if project ongoing activities would produce groundborne vibrations that are perceptible without instruments by a reasonable person at the property lines of the site. Construction Groundborne noise is generated when vibrating building components radiate sound, or noise generated by groundborne vibration. In general, if groundborne vibration levels are do not exceed levels considered to be perceptible, then groundborne noise levels would not be perceptible in most interior environments. Therefore, this analysis focuses on determining exceedances of groundborne vibration levels. Construction activity can result in varying degrees of ground vibration, depending on the equipment used on the site. Operation of construction equipment causes vibrations that spread through the ground and diminish in strength with distance. Buildings in the vicinity of a construction site respond to these vibrations with varying results ranging from no perceptible effects at the low levels, to slight damage at the highest levels. Impact equipment, such as pile drivers, are not expected to be used during construction of the project. Therefore, of the variety of equipment used during construction of this component of the project, the small vibratory rollers that would be used in the site preparation phase of construction would produce the greatest groundborne vibration levels. As shown in Table 3.11-3, small vibratory rollers produce groundborne vibration levels ranging up to 0.101 in/sec PPV at 25 feet from the operating equipment. The nearest off-site receptor to where the heaviest construction equipment would operate are the multi-family residential homes, approximately 20 feet south of the nearest construction footprint for Contra Costa County–Oak Road Townhouse Condominiums Project Noise Draft EIR 3.11-22 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx the project. As measured at the nearest receptor, operation of a small vibratory roller could result in groundborne vibration levels up to 0.141 in/sec PPV. This is below the FTA’s damage threshold criteria of 0.2 in/sec PPV for non-engineer timber and masonry buildings. Therefore, construction-related groundborne vibration impacts to off-site receptors would be less than significant. Operation Contra Costa County and the City of Walnut Creek have not adopted criteria for operational groundborne vibration impacts. Therefore, for purposes of this analysis, a significant impact would occur if project ongoing activities would produce groundborne vibrations that are perceptible without instruments by a reasonable person at the property lines of a site. Implementation of the project would not include any permanent sources of vibration that would expose persons in the project vicinity to groundborne vibration levels that could be perceptible without instruments at any existing sensitive land use in the vicinity of the project site. Therefore, operational groundborne vibration impacts would be less than significant. Level of Significance Less than significant impact. Excessive Noise Levels from Airport Activity Impact NOI-4: The proposed project would not expose people residing or working in the project area to excessive noise levels for a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport. A significant impact would occur if the proposed project would expose people residing or working in the project area to excessive noise levels for a project located in the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within 2 miles of a public airport or public use airport. The project site is not located within the vicinity of a private airstrip. The nearest public airport to the project site is the Buchanan Field Airport, located approximately 4.5 miles north of the project site. According to the airport’s noise contour map, the project site is located outside of the 65 dBA CNEL airport noise contours. While aircraft noise is occasionally audible on the project site from aircraft flyovers, aircraft noise associated with nearby airport activity would not expose people to residing or working near the project site to excessive noise levels. Therefore, implementation of the project would not expose persons residing or working in the project vicinity to noise levels from airport activity that would be in excess of normally acceptable standards for the proposed land use development and no impact would occur. Level of Significance No impact. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Noise FirstCarbon Solutions 3.11-23 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx 3.11.6 - Cumulative Impacts Noise Land Use Compatibility Consistency Combined cumulative year traffic and BART activity noise levels at the project site would result in noise levels that Contra Costa County considers to be conditionally acceptable for new multi-family residential land uses (with projected noise levels of up to 74 dBA DNL at the highest impacted façade). This impact is potentially significant. However, as discussed under Impact NOI-1, MM NOI-1 shall be implemented, which requires the project to include a code compliant mechanical ventilation system that would permit windows to remain closed for prolonged periods, as well as upgraded window and door assemblies to ensure compliance with the interior noise standard of 45 dBA DNL. This measure would ensure that potentially impacted interior residential units would meet the interior noise level requirement of 45 dBA DNL. Therefore, implementation of MM NOI-1 would ensure that the project would not result in a cumulatively considerable contribution to consistency with noise land use compatibility standards. Therefore, with implementation of MM NOI-1, the project would result in a less than significant cumulative impact related to land use compatibility consistency. Construction Noise Temporary Substantial Increase The geographic scope of the cumulative noise analysis is the project vicinity, including surrounding sensitive receptors. Noise impacts tend to be localized; therefore, the area near the project area (approximately 0.25 mile) would be the area most affected by proposed plan activities. However, none of the cumulative projects shown in Table 3 -1 are located within 0.25 mile of the project site. Therefore, the project would result in a less than significant cumulative impact related to construction noise. Operational Traffic Noise Permanent Substantial Increase The significance threshold for a cumulative traffic noise impact would be traffic noise levels that would cause the DNL to increase by 1.5 dBA or more where the DNL currently exceeds conditionally acceptable levels. As shown in the traffic analysis prepared for the project, the intersection volume data indicates that project-related peak-hour traffic volumes will increase roadway traffic volumes by 3 percent or less, which corresponds with less than a 1 dB increase in the traffic noise levels DNL. Therefore, project- related traffic noise level would result in less than significant increases in traffic noise levels along modeled roadway segments in the project vicinity. This would be a less than significant impact, and no mitigation would be required. Given the above information, the project, in conjunction with other existing, planned, and probable future projects, would result in a less than significant cumulative impact related to noise. Operational Stationary Noise Permanent Substantial Increase Implementation of the project would introduce new stationary noise sources to the ambient noise environment in the project vicinity, including new mechanical ventilation equipment. However, noise levels generated by this equipment would attenuate to below 58.5 dBA Leq at the closest residential Contra Costa County–Oak Road Townhouse Condominiums Project Noise Draft EIR 3.11-24 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-11 Noise.docx receptor. These noise levels would not exceed documented existing background ambient noise levels. Therefore, implementation of the project would not result in a cumulatively considerable contribution to existing ambient noise conditions in the project vicinity. This impact would be less than significant. Construction and Operational Vibration The only cumulatively considerable contribution to vibration conditions in the project vicinity would result from introduction of new permanent sources of groundborne vibration in the project site vicinity. The only major sources of groundborne vibration in the project vicinity is railroad activity along the rail line west of the project site. Implementation of the project would not introduce any new permanent sources of groundborne vibration to the project vicinity and would not increase railroad activity. Therefore, implementation of the project would not result in a cumulatively considerable contribution to vibration conditions in the project vicinity. This impact would be less than significant. Level of Cumulative Significance Before Mitigation Potentially significant impact (traffic noise land use compatibility only). Mitigation Measures Implement MM NOI-1. Level of Cumulative Significance After Mitigation Less than significant impact.

This section also evaluates the possible impacts related to population and housing that could result from implementation of the project. Information included in this section is based on databases and reports maintained by the California Department of Finance (CDF), Association of Bay Area Governments (ABAG), and Contra Costa County (County). During the Notice of Preparation (NOP) comment period, the following comments were received related to the proposed project regarding Population and Housing: • Concern regarding increased density due to the proposed project (offered less dense, community-oriented alternatives to the proposed project). • Walnut Creek needs housing, but it should be affordable housing. 3.12.2 - Existing Conditions Population and Housing San Francisco Bay Area The ABAG conducts long-term forecasts of population, households, and employment for the nine county 1 San Francisco Bay Area (Bay Area) to project growth in the region. The Bay Area has experienced population growth over the past several decades, and that growth is expected to continue. The ABAG 2018 projection estimated that approximately 7,920,230 residents would reside in the Bay Area in 2020. The ABAG projects that the Bay Area’s population will grow by approximately 1,732,720 new residents between 2020 and 2040 and reach approximately 9,652,950 residents by 2040.2 Contra Costa County Population and housing characteristics for the County are summarized in Table 3.12-1.3 This includes for the entire County and the unincorporated areas. Unincorporated areas account for 15 percent of the County’s population and have slightly smaller household sizes than the Countywide average.

The total County population grew by 43 percent during the 30-year time period with the bulk of the growth occurring in incorporated cities and towns. Unincorporated areas grew at a slower rate (14 percent) in large part due to land use policies that promote city-centered growth.

Affordable Housing Contra Costa County In July 2013, the ABAG projected regional housing needs in its Regional Housing Needs Plans for the San Francisco Bay Area: 2015-2023. According to the ABAG forecasts, unincorporated Contra Costa County’s projected housing need from 2015 to 2023 is 1,367 residential units, consisting of: • 374 units within the very-low-income level (0–50 percent of area median income); • 218 units within the low-income level (51–80 percent of area median income); • 243 units within the moderate-income level (81–120 percent of area median income); and • 532 units within the above-moderate-income level (more than 120 percent of area median income).5 Project Site There are no residences, including affordable housing units, on the project site. Employment San Francisco Bay Area The Bay Area region has experienced a strong recovery since the 2007–2009 Great Recession, with job growth proceeding at a pace greater than that experienced by the State of California or the United States as a whole. By mid-2013, the Bay Area had regained all of the jobs lost during the Great Recession; however, if 2000 is used as the baseline year, the average rate of growth is much less and closer to zero since the peak of the dot-com boom era.6 The Draft Environmental Impact Report (Draft EIR) (currently under public review until July 20, 2021) for the forthcoming ABAG Plan Bay Area 2050 indicates that employment in the Bay Area is expected to grow from 4,005,500 in 2015 to 5,408,000 in 2050.7 Contra Costa County The California Employment Development Department (EDD) estimated that in May of 2021, the County had 499,500 employed persons and 33,500 unemployed persons for an unemployment rate of 6.3 percent within the County.8 According to the U.S. Bureau of Labor Statistics, in April of 2021, the State of California has an unemployment rate of 8.3 percent.9 5 Association of Bay Area Governments (ABAG).

The school is currently closed and does not offer employment. There are no land uses, such as commercial or office space, on the project site that offer employment. 3.12.3 - Regulatory Setting Federal No federal plans, policies, regulations, or laws related to population and housing are applicable to the project. State Regulations California Housing Element Law The State Housing Element Law (Government Code Chapter 1143, Article 10.6, §§ 65580 and 65589) requires each city and county to adopt a general plan for future growth. This plan must include a housing element that identifies housing needs for all economic segments and provides opportunities for housing development to meet that need. The amount of housing that must be accounted for in a local housing element is determined through a process called the Regional Housing Needs Allocation (RHNA). In the RHNA process, the State gives each region a number representing the amount of housing needed, based on existing need, and expected population growth. At the State level, the California Department of Housing and Community Development (HCD) estimates the relative share of the State’s anticipated population growth that would occur in each county in the State, based on CDF population projections and historic growth trends. Where there is a regional council of governments, as in the San Francisco Bay Area (in this case, the ABAG), the HCD provides the regional housing need to the council. The council then assigns a share of the regional housing need to each of its cities and counties. The process of assigning shares provides cities and counties the opportunity to comment on the proposed allocations. The HCD oversees the process to ensure that the council of governments distributes its share of the State’s projected housing need. Each city and county must update its general plan housing element on a regular basis pursuant to the requirements of Government Code Section 65580, et seq. Among other things, the housing element must incorporate policies and identify potential sites that would accommodate a city’s share of the regional housing need. Before adopting an update to its housing element, a city or county must submit the draft to the HCD for review. The HCD will advise the local jurisdiction whether its housing element complies with the provisions of California Housing Element Law. The regional councils of governments are required to assign regional housing shares to the cities and counties within their region on a similar schedule. At the beginning of each cycle, the HCD provides population projections to the regional councils of governments, who then allocate shares to their cities and counties. The shares of the regional need are allocated before the end of the cycle so that the cities and counties can amend their housing elements by the deadline.

The Plan Bay Area functions as the sustainable communities’ strategy mandated by Senate Bill 375. Updating the 2040 document, Plan Bay Area 2050 has been updated as a long-range plan charting the course for the future of the nine county Bay Area. This updated plan is expected to be adopted by MTC and ABAG in Fall 2021.10 In July 2013, the ABAG projected regional housing needs in its RHNA for the San Francisco Bay Area: 2014–2022. Updated RHNA projections are expected in the second half of 2021. Acting in coordination with the HCD, the ABAG determines the Bay Area’s regional housing need based on regional trends, projected job growth, and existing needs. Unincorporated Contra Costa County’s fair share of the regional housing need allocation for an 8-year period (2015 to 2023) was calculated as 1,367 units, or about 171 units per year. Updated RHNA projections are expected in the second half of 2021. The RHNA determination includes production targets addressing the housing needs of a range of household income categories. A total of about 592 units, or 43 percent of the RHNA target, must be affordable to households making up to 80 percent of the area’s median income.11 The United States Department of Housing and Urban Development (HUD) determines the annual area median income for the Oakland-Fremont Metropolitan Statistical Area, which includes Contra Costa County. In 2021, the area’s median family income was $125,600. For families of low income (including 80 percent of the population), the median family income for a single-person household was $76,750 and for a 4-person family it was $109,600.12 Local Contra Costa County General Plan Land Use Element Applicable policies found in the General Plan Land Use Element include the following: Policies Policy 3-5 New development within unincorporated areas of the County may be approved, providing growth management standards and criteria are met or can be assured of being met prior to the issuance of building permits in accordance with the growth management program.

Contra Costa County Ordinance Code Inclusionary Housing Ordinance Chapter 822-4, Inclusionary Housing Ordinance, of the Ordinance Code facilitates the development and availability of housing affordable to a broad range of households with varying income levels within the County. A residential development consisting of five to 125 for-sale units must develop and sell at least 15 percent of the for-sale units as inclusionary units. However, as an alternative to providing some or all of the inclusionary units required, an in-lieu fee may be paid pursuant to Ordinance Code Section 822-4.404. The fee paid is established by the County’s Department of Conservation and Development fee schedule as adopted by the Board of Supervisors. 3.12.4 - Impacts and Mitigation Measures Significance Criteria According to the California Environmental Quality Act (CEQA) Guidelines Appendix G Environmental Checklist, to determine whether impacts to population and housing are significant environmental effects, the following questions are analyzed and evaluated. Would the project: a) Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? Approach to Analysis Impacts related to population, housing, and employment were determined by analyzing existing and projected population, housing, and employment estimates provided by the CDF, ABAG, and the General Plan. The proposed project’s impacts were evaluated by determining their consistency with these projections, estimates, and the General Plan. Specific Thresholds of Significance For purposes of this analysis, the following thresholds are used to evaluate the significance of population and housing impacts resulting from implementation of the project. • Inducement of permanent or daytime population or employment growth in the Contra Costa County General Plan planning area that would exceed Contra Costa County or ABAG population projections for Contra Costa County. • Displacement of existing housing or permanent population.

Construction Impacts related to inducement of population growth are limited to operational impacts. No respective construction impacts would occur. Operation Direct Population Growth The proposed project would develop 125 new dwelling units on the project site. Table 3.12-4 summarizes project-related population growth. As shown in the table, the proposed project would add an estimated 357 persons to the County’s population. This would represent an increase of 0.2 percent relative to the unincorporated population of 174,423. This amount of population growth would be within the General Plan’s 2020 population and dwelling projections for the unincorporated area and, therefore, would not be considered substantial. Furthermore, it would also be within ABAG’s 2020-2040 regional population growth projections. Impacts would be less than significant.

Indirect Population Growth The proposed project is exclusively residential; it would not create new permanent employment opportunities. Thus, no indirect population growth from new employment would occur. The project site has been developed since the 1930s and is located within an urbanized area of the unincorporated County. It is served with urban infrastructure and utilities including potable water, sewer, storm drainage, electricity, and natural gas. As such, the proposed project would not remove a barrier of growth through the extension of infrastructure or utilities to an unserved area. Impacts would be less than significant. Level of Significance Less than significant impact.

Construction Impacts related to displacement of people or housing necessitating replacement housing are limited to operational impacts. No respective construction impacts would occur. Operation The site contains two existing residential units that are occupied by the property owners’ family members serving as caretaker and security for the property and existing improvements. Removal of these existing uses would not result in the displacement of substantial numbers of persons or housing. No impact would occur. Level of Significance No impact. 3.12.5 - Cumulative Impacts Cumulative population and housing effects must be considered in relationship land use, plans, and policy considerations for development facilitated by the General Plan. The relevant cumulative geographic context is the unincorporated area of the County that includes projects identified in Chapter 3, Environmental Impact Analysis, Table 3 -1, Cumulative Projects. Population Growth The geographic scope of the cumulative population and housing analysis is Contra Costa County. As of 2021, the County was estimated to have a population of 1,153,854, with unincorporated areas having a population of 174,423. Cumulative projects listed in Table 3-1 in conjunction with the project would add population. The proposed project would add 357 persons to the County’s population, which would represent growth of less than 0.01 percent of the County’s population and 0.02 of the unincorporated population. As such, there would not be substantial direct population growth associated with the proposed project in conjunction with the cumulative projects. Therefore, cumulative impacts related to population growth, both direct and indirect, would be considered less than significant. Population/Housing Displacement Cumulative projects listed in Table 3-1 in conjunction with the proposed project would add residential units to the County. None of the listed projects substantially displaces housing units or people within the County. In fact, implementation of the cumulative projects would result in a net increase of housing in the County. The County further requires development that may impact housing to include affordable housing units or pay a related impact fee (see Regulatory Setting). Therefore, cumulative impacts associated with population and housing displacement would be less than significant. Level of Cumulative Significance Less than significant impact.

This section also evaluates the possible impacts related to public services and parks and recreational facilities that could result from implementation of the proposed project. Information in this section is based on information obtained from the Contra Costa County General Plan (General Plan), Contra Costa County Fire Protection District (CCCFPD), Contra Costa County Office of the Sheriff, Walnut Creek Elementary School District, Acalanes Union High School District (AUHSD), and East Bay Regional Park District (EBRPD). During the Notice of Preparation (NOP) comment period, the following comment was received related to the proposed project regarding Public Services and Recreation: • The proposed project would crowd area walking trails and neighborhood parks that are already congested. 3.13.2 - Environmental Setting Fire Protection and Emergency Medical Services Northern California California Department of Forestry and Fire Protection (CAL FIRE) is responsible for fire protection and stewardship of over 31 million acres of California’s privately owned wildlands. CAL FIRE also provides varying levels of emergency services in 36 of the California’s 58 counties via contracts with local governments. Because of the Department’s size and major incident management experience, it is often asked to assist or take the lead in disasters.1 In October 2017, a series of wildfires occurred in Northern California resulting in extensive property damage. In November 2018, the Camp Fire wildfire occurred in Northern California, resulting in the deadliest wildfire to occur in State history.2 In September and October 2020, the Glass Fire burned over 67,484 acres and destroyed 1,555 structures, Napa, and Sonoma Counties.3 In August 2020, the North Complex Fire and the LNU Lightning Complex burned approximately 318, 935 and 363, and 220 acres respectively in several counties in Northern California, and destroyed 2,352 and 1,491 structures respectively.4 Contra Costa County The CCCFPD provides fire protection and emergency medical services in and around the 19 cities and unincorporated communities of Contra Costa County. The CCCFPD serves the County with 26 fire stations, and with few exceptions, County emergency ambulance transport services are provided by 1 California Department of Forestry and Fire Protection (CAL FIRE). 2021.

The Operations Division maintains 24 fully staffed stations, and two more stations staffed with paid on-call Reserve Firefighters. The 24 on-duty companies are trained and regularly cross-staff numerous specialty response units including 18 wildland fire apparatus, three rescue units, a trench rescue unit, a fire rescue boat, and a mobile breathing air support unit.6 According to the General Plan, wildfire hazards are a considerable problem in undeveloped areas and in areas of extensive un-irrigated vegetation. Areas of Central Contra Costa County that contain steep slopes and are covered with natural vegetation (e.g., Mount Diablo State Park, Briones Regional Park, and Tilden Regional Park) as well as areas in East County outside the urban limit line that are used as dry farming of grains for feed are extremely flammable during the late summer and fall.7 Project Site There are no fire protection or emergency medical facilities on the project site. There are four fire stations located within approximately 2 miles of driving distance of the project site: Station No. 1, located at 1330 Civic Drive in Walnut Creek, is approximately 1.7 miles (driving distance) south of the project site; Station No. 2, located at 2012 Geary Road in Pleasant Hill, is approximately 1.4 miles (driving distance) west of project site, Station No. 5, located 205 Boyd Road in Pleasant Hill, is approximately 1.9 miles (driving distance) north of the project site; and Station No. 10, located at 2955 Treat Boulevard in Concord, is approximately 2.2 miles (driving distance) northeast of the project site.8 Police Protection Contra Costa County The Contra Costa County Office of the Sheriff provides law enforcement to unincorporated areas of the County and serves over one million County residents. The Office of the Sheriff employs over 1,100 staff members, including nearly 700 sworn personnel. Sworn staff provide unincorporated area policing, air support (helicopters), marine patrol, dispatch, investigations, coroners, County detention facilities, custody alternatives, court security, forensic services, a police academy, and an Office of Emergency Services in unincorporated parts of the County.

The AUHSD serves students in grades 9-12 and has an extensive adult education program. It includes four comprehensive high schools, one alternative school, and one adult education center.17 Project Site The former Palmer School for Boys and Girls, a private K-8 school, operated at the project site from 1939 until its closure due to COVID-19 in June 2020. However, no active school currently exists on the project site, and there are no existing residences within the project site requiring school service needs. The project site is located within the boundaries of the WCSD, which serves grades TK-8 and AUHSD which serves grades 9-12. The proposed project would be served by Buena Vista Elementary School (K-5), located approximately 0.9 mile to the southwest, by Walnut Creek Intermediate School, located approximately 1 mile to the southeast, and by Las Lomas High School, located approximately 2.24 miles to the south. Libraries Contra Costa County There are several local libraries that serve Contra Costa County and are under the Contra Costa County Library system. Table 3.13-2 summarizes the library branches, the distance of each library branch from the project site, their hours of operation, and the services they offer.

The DPR manages and preserves 1,650,779 acres within 280 parks and 4,700 miles of trails.18 One State park, Mount Diablo State Park, is located within 10 miles of the project site. State Parks Mount Diablo State Park Mount Diablo State Park is located approximately 5 miles east of the project site. The approximately 20,000-acre park contains open land for camping, hiking, picnicking, horseback riding, mountain biking, and other recreational opportunities.19 Park gates are open year-round from 8:00 a.m. to sunset.20 Project Site There are no State parks, recreational facilities, or designated open spaces on the project site. Regional Parks The EBRPD offers regional parklands and trails in Alameda and Contra Costa counties. The EBRPD manages and preserves nearly 125,000 acres in 73 parks, including 1,250 miles of trails and 55 miles of shoreline.21 Two regional parks are located within 5 miles of the project site: Diablo Foothills Regional Park and Briones Regional Park. Additionally, the project site is located near the Contra Costa Canal Trail, the Iron Horse Trail, and the Briones to Mount Diablo Trail. However, residents of Contra Costa County use regional parks and regional trails outside of their immediate vicinity, so future residents of the proposed project could increase use an any of the EBRPD parks.22 The EBRPD regional parks and regional trails serving the project site generally meet the current needs of existing County residents and are in generally good condition. The COVID-19 pandemic has greatly increased the use of both local and regional parks, serving the public as a valuable space for safe, outdoor recreation. EBRPD strives to provide high-quality and safe recreational opportunities to all residents and visitors to the County and the adjacent Alameda County.23 Diablo Foothills Regional Park The Diablo Foothills Regional Park is located approximately 4.3 miles southeast of the project site, in the City of Walnut Creek. The 1,060-acre park contains open land for horseback riding, hiking, bicycling, and nature study. There are no developed facilities in the park.

Project Site There are no existing local community parks, recreational facilities, or designated open spaces on the project site. Exhibit 3.13-1 displays the parks, open spaces, and regional parks in the vicinity of the project site. The former Palmer School for Boys and Girls, a private elementary school, operated at the project site from 1939 until its closure due to COVID-19 in June 2020. The school grounds include several recreational facilities such as tennis courts, basketball courts, playgrounds, and a swimming pool, as well as additional open space and landscaping. These facilities were available only to students at the former school and are not open to the public. As part of the proposed project, all existing facilities would be demolished. 3.13.3 - Regulatory Framework Federal No federal plans, policies, regulations, or laws related to public services and recreation are applicable to the proposed project. State California Fire Code and California Building Code The International Fire Code and the International Building Code, established by the International Code Council (ICC) and amended by the State of California, prescribe performance characteristics and materials to be used to achieve acceptable levels of fire protection. California Health and Safety Code California Health and Safety Code, Sections 13100–13135, establish the following policies related to fire protection: • Section 13100.1: The functions of the office of the State Fire Marshall, including CAL FIRE, shall be to foster, promote, and develop strategies to protect life and property against fire and panic. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Public Services and Recreation FirstCarbon Solutions 3.13-11 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-13 Public Services and Rec.docx Section 13104.6: The Fire Marshall has the authority to require fire hazards to be removed in accordance with the law relating to removal or public nuisances on tax-deeded property. California Senate Bill 50 Senate Bill (SB) 50 (funded by Proposition 1A, approved in 1998) limits the power of cities and counties to require mitigation of school facilities impacts as a condition of approving new development, and provides instead for a standardized developer fee. SB 50 generally provides for a 50/50 State and local school facilities funding match. SB 50 also provides for three levels of statutory impact fees. The application level depends on whether State funding is available, whether the school district is eligible for State funding, and whether the school district meets certain additional criteria involving bonding capacity, year-round school, and percentage of movable classrooms in use. California Government Code, Section 65995(b) and Education Code, Section 17620 SB 50 amended Section 65995 of the California Government Code, which contains limitations on Section 17620 of the Education Code, the statute that authorizes school districts to assess development fees within school district boundaries. Section 65995(b)(3) of the Government Code requires the maximum square footage assessment for development to be increased every 2 years, according to inflation adjustments. On January 22, 2014, the State approved increasing the allowable amount of statutory school facilities fees (Level I School Fees) from $3.20 to $3.36 per square foot of assessable space for residential development of 500 square feet or more, and from $0.51 to $0.54 per square foot of chargeable covered and enclosed space for commercial/industrial development. School districts may levy higher fees if they apply to the State and meet certain conditions. Quimby Act The Quimby Act (California Government Code § 66477) was established by the California Legislature in 1965 to preserve open space and parkland in rapidly urbanizing areas of the State. The Quimby Act allows cities and counties to establish requirements for new development to dedicate land for parks, pay an in lieu fee, or provide a combination of the two. The Quimby Act provides two standards for the dedication of land for use as parkland. If the existing area of parkland in a community is greater than 3 acres per 1,000 residents, then the community may require dedication based on a standard of up to 5 acres per 1,000 persons residing in the subdivision based on the current ratio of parkland per 1,000 residents. If the existing amount of parkland in a community is less than 3 acres per 1,000 residents, then the community may require dedication based on a standard of only 3 acres per 1,000 persons residing in the subdivision. The Quimby Act requires a city or county to adopt standards for recreational facilities in its general plan to adopt a parkland dedication or fee ordinance. The General Plan includes criteria and standards for County parks, 26 and therefore can require the payment of development fees and/or dedication of land pursuant to Chapter 920-2 of the Contra Costa County Ordinance Code (Ordinance Code).27 26 Contra Costa County. 2005.

Therefore, the Quimby Act effectively preserves open space needed to develop park and recreation facilities, but it does not ensure the development of the land or the provision of park and recreation services to residents. In addition, the Quimby Act applies only to residential subdivisions. Nonresidential projects could contribute to the demand for park and recreation facilities without providing land or funding for such facilities. Quimby Act fees are collected by the local agency (park district, city, or county) in which the new residential development is located. Local Contra Costa County General Plan General Plan Public Facilities/Services Element The General Plan Public Facilities/Services Element sets forth the following applicable goals and policies that are relevant to public facilities/services: Goal 7-A To give a high priority to funding quality civic, public, and community facilities which serve a broad range of needs throughout the County. Goal 7-B To permit development in unincorporated areas only when financing mechanisms are in place or committed which assure that adopted performance standards in the growth management program will be met. Goal 7-C To utilize equitable financing methods which assure that adopted performance standards are achieved. Goal 7-D To cooperate with other local jurisdictions to promote the most cost-effective methods of providing public facilities necessary for supporting the economic, social, and environmental well-being of the County and its residents. Goal 7-E To resolve conflicts with other jurisdictions regarding the location of revenue generating land uses. Policies Policy 7-1 New development shall be required to pay its fair share of the cost of all existing public facilities it utilizes, based upon the demand for these facilities which can be attributed to new development. Policy 7-2 New development, not existing residents, should be required to pay all costs of upgrading existing public facilities or constructing new facilities which are exclusively needed to serve new development. Policy 7-4 The financial impacts of new development or public facilities should generally be determined during the project review process and may be based on the analysis contemplated under the Growth Management Element or otherwise. As part of the project approval, specific findings shall be adopted which relate to the demand for new public facilities and how the demand affects the service standards included in the growth management program.

Contra Costa County Ordinance Code Division 920—Park Dedications As a condition of approval of a subdivision, developers are required to dedicate land, pay a fee in lieu thereof, or do a combination of both, for neighborhood and community park or recreational purposes. The total area required to be dedicated is based on a figure of 3 acres of park per 1,000 persons. 3.13.4 - Impacts and Mitigation Measures Significance Criteria According to the California Environmental Quality Act (CEQA) Guidelines Appendix G Environmental Checklist, to determine whether impacts related to public services are significant environmental effects, the following question is analyzed and evaluated. Would the project: Result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for any of the public services: a) Fire protection b) Police protection c) Schools d) Other public facilities Would the project: a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? b) Include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment? Contra Costa County–Oak Road Townhouse Condominiums Project Public Services and Recreation Draft EIR 3.13-16 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-13 Public Services and Rec.docx Approach to Analysis Impacts on fire and police services were determined by evaluating the proposed project’s effect on existing fire and police station response times. Projected population provided by the General Plan was also reviewed. In addition, fire, and police (emergency) access at the project site was evaluated. Impacts on schools were determined by evaluating the proposed project’s effect on existing school enrollment. Projected population and school enrollment data provided by the General Plan, WCSD, and Department of Education were also reviewed. Impacts related to parks and recreational facilities were determined by evaluating the proposed project’s effect on existing park and recreational facility usage levels. Furthermore, impacts to police, fire, schools, library facilities, and local and regional parks were also based on estimates and information received in response to request letters sent to each of these service providers for their input related to possible project impacts. Specific Thresholds of Significance For purposes of this analysis, the following thresholds are used to evaluate the significance of public service and recreation impacts resulting from implementation of the proposed project. • Result in additional population or activities requiring fire protection services in a manner that necessitates the need for new or altered fire facilities, the construction of which would result in significant construction-related transportation, air quality, greenhouse gas (GHG) emissions, energy, or noise impacts. Determination of significance of construction-related traffic, air quality, GHG emissions, or noise impacts is based on the respective specific thresholds of significance listed in Section 3.14, Tr ansportation; Section 3.2, Air Quality; Section 3.7, Greenhouse Gas Emissions; Section 3.5, Energy; and Section 3.11, Noise. • Result in additional population or activities requiring police protection services in a manner that necessitates need for new or altered police facilities, the construction of which would result in significant construction-related transportation, air quality, GHG emissions, energy, or noise impacts. Determination of significance of construction-related traffic, air quality, GHG emissions, or noise impacts is based on the respective specific thresholds of significance listed in Section 3.14, Transportation; Section 3.2, Air Quality; Section 3.7, Greenhouse Gas Emissions; Section 3.5, Energy; and Section 3.11, Noise. • Result in additional population or activities requiring school services in a manner that necessitates need for new or altered school facilities, the construction of which would result in significant construction-related transportation, air quality, GHG emissions, energy, or noise impacts. Determination of significance of construction-related traffic, air quality, GHG emissions, or noise impacts is based on the respective specific thresholds of significance listed in Section 3.14, Transportation; Section 3.2, Air Quality; Section 3.7, Greenhouse Gas Emissions; Section 3.5, Energy; and Section 3.11, Noise. • Result in additional population or activities requiring library services in a manner that necessitates need for new or altered library facilities, the construction of which would result in significant construction-related transportation, air quality, GHG emissions, energy, or noise impacts. Determination of significance of construction-related traffic, air quality, GHG emissions, or noise impacts is based on the respective specific thresholds of significance listed in in Section 3.14, Transportation; Section 3.2, Air Quality; Section 3.7, Greenhouse Gas Emissions; Section 3.5, Energy; and Section 3.11, Noise.

Impact Evaluation Need for New or Altered Fire Protection Facilities Impact PUB-1: The proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered fire protection facilities, need for new or physically altered fire protection facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for fire protection. Four fire stations are located within approximately 2 miles of driving distance of the project site: Station No. 1, located at 1330 Civic Drive in Walnut Creek, is approximately 1.7 miles (driving distance) south of the project site; Station No. 2, located at 2012 Geary Road in Pleasant Hill, is approximately 1.4 miles (driving distance) west of project site, Station No. 5, located 205 Boyd Road in Pleasant Hill, is approximately 1.9 miles (driving distance) north of the project site; and Station No. 10, located at 2955 Treat Boulevard in Concord, is approximately 2.2 miles (driving distance) northeast of the project site.28 Using an average travel speed of 35 miles per hour (mph), a fire engine would be able to reach construction areas at the project site from Station No. 2 (approximately 1.4 miles of driving distance) in 2 minutes and 24 seconds, which is under the 5-minute response standard set by the County General Plan.29 As part of project construction, the proposed project would comply with the California Building Standards Code (CBC), which is adopted by the Ordinance Code. In compliance with the California Fire Code, Part 9 of the CBC, during construction the proposed project would follow standards for fire safety related to provision of fire apparatus access and acquisition of building permits. Specifically, CBC Section 105.7.17 requires plans be submitted and a permit is required to install, improve, modify, or remove public or private roadways, driveways, and bridges for which Fire District access is required by the Fire Code; this would ensure adequate driveway/entry turning radius, height clearance, and fire hydrant access for fire trucks and engines at the project site during construction. In addition, CBC Section 105.7.18 requires plans be submitted to the Fire Code Official for all land developments or for the construction, alteration, or renovation of a building within the jurisdiction where a building permit is required; this would ensure that construction and alteration would not obstruct CCCFPD from delivering adequate levels of fire protection services.30 With an adequate fire engine response time to the project site and adherence to the aforementioned CBC Code sections, construction of the proposed project would not create 28 Contra Costa County Fire Protection District (CCCFPD). 2014.

Therefore, construction impacts related to need for new or altered fire protection facilities would be less than significant. Operation The operation of new townhouses on the project site would result in new residents at the project site and could in turn result in an increase in calls for fire protection and emergency medical services. As noted above, Fire Station No. 2, at 2012 Geary Road, is approximately 1.4 miles west of the project site, and could reach the site within 2 minutes and 24 seconds, which is below the 5- minute response standard set by the General Plan.31 As part of project operation, the proposed project would comply with the CBC, which is adopted by the Ordinance Code. Specifically, in compliance with the California Fire Code, Part 9 of the CBC, during operation the proposed project would follow standards for fire safety such as fire flow requirements for buildings, fire hydrant location and distribution criteria, automated sprinkler systems, and fire- resistant building materials. Primary vehicle access to the project site would be from a driveway on Oak Road and a driveway on Jones Road. Oak Road is a public local street under the jurisdiction of the City of Walnut Creek. It runs north–south along the project site east frontage. Jones Road is a public County local street that runs along the project site west frontage. Thus, during project operation, emergency vehicles would not have difficulty accessing the project site, as also further discussed under Impact TRANS-4, Emergency Access, in Section 3.14, Transportation. As such, it is not expected that the proposed project would adversely affect response times or increase the use of existing fire protection or emergency medical response facilities such that substantial physical deterioration, alteration, or expansion of these facilities would be required, thereby triggering environmental impacts. Furthermore, the project applicant would be required to pay applicable fees toward fire protection facilities and apparatus, so that the CCCFPD can maintain fire safety standards. With an adequate fire engine response time to the project site, adherence to the aforementioned CBC Code sections, adequate project site access, and payment of impact fees to the CCCFPD, operation of proposed project would not create a need to construct new or expand existing fire protection or emergency medical services facilities. Therefore, operational impacts related to need for new or altered fire protection facilities would be less than significant. Level of Significance Less than significant impact. Need for New or Altered Police Protection Facilities Impact PUB-2: The proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered police protection facilities, need for new or physically altered police protection facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for police protection. 31 Contra Costa County. 2005. Contra Costa County General Plan. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Public Services and Recreation FirstCarbon Solutions 3.13-19 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-13 Public Services and Rec.docx Construction The Office of the Sheriff would provide law enforcement services to the project site during construction. The nearest Sheriff station to the project site is the Valley Station at 150 Alamo Plaza Unit C, located 6.7 miles (driving distance) southeast of the project site; however, response is not likely to originate from this station but rather from Sheriff Deputies or Walnut Creek police officers pursuant to mutual aid patrolling the local beat. If response calls originated from the Valley Station, response would be approximately 11 minutes and 29 seconds to the project site, assuming an average travel speed of 35 mph driving speed. During construction, the proposed project would also implement security measures such as provision of a project-boundary fence to prohibit access to persons other than construction personnel. With an adequate police response time to the project site and provision of adequate security measures, construction of, the proposed project would not create the need for new or altered police protection facilities. Therefore, construction impacts related to need for new or altered police protection facilities would be less than significant. Operation The operation of new townhouses on the project site would result in new residents at the project site and could in turn result in an increase in calls for police protection services. Primary access to the project site during operation would be from Oak Road and Jones Road. The project site is located 6.7 miles from the Valley Station; however, responses to calls are not likely to originate from the station but rather from Sheriff Deputies or Walnut Creek police officers pursuant to mutual aid patrolling the local beat. Since there are many factors in evaluating response times, the Office of the Sheriff does not set a specific goal for emergency call response times. However, County General Plan Policy 7-59 indicates that when making staffing and beat configuration decisions, the Sheriff should strive for a maximum response time for Priority 1 or 2 calls of 5 minutes for 90 percent of all emergency responses in central business district, urban, and suburban areas. This General Plan Policy indicated response time is a goal, not a requirement. The County General Plan Policy 7-57 indicates a Sheriff facility standard of 155 square feet of Sheriff station space per 1,000 persons of population. The square footage of the Valley Station is estimated to be approximately 5,372 square feet. The proposed project would increase the population of unincorporated Contra Costa County by approximately 357 persons. Accordingly, the proposed project would require 55 square feet of Sheriff station space. This increased demand for Sheriff station space represents approximately 1 percent of the Valley Station’s existing square footage and, thus, represents a nominal increase in demand. Furthermore, the Office of the Sheriff did not indicate that the proposed project would result in the need for new or expanded Sheriff facilities in order to maintain acceptable service ratios, response times, or other performance objectives. As such, the proposed project would not adversely affect service ratios or response times or increase the use of existing police protection facilities such that substantial physical deterioration, alteration, or expansion of these facilities would be required, thereby triggering environmental impacts. Furthermore, the project applicant would be required to pay applicable fees to the Office of the Sheriff to help provide for the costs associated with a police facilities building and equipment to serve additional demands for police services.

Therefore, operational impacts related to need for new or altered police protection facilities impacts would be less than significant. Level of Significance Less than significant impact. Need for New or Altered School Facilities Impact PUB-3: The proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered school facilities, need for new or physically altered school facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios or other performance objectives for schools. Construction Impacts related to provision of and need for construction of new or expanded school facilities are limited to operational impacts. No respective construction impacts would occur. Operation WCSD provides school services from TK through eighth grade to the majority of the City of Walnut Creek, as well as to unincorporated area adjacent to it. The district is responsible for meeting the educational needs of approximately 3,600 students at five elementary schools and one intermediate school.32 The project site is located within the WCSD (grades K–8) and AUHSD (grades 9 –12). Elementary school age residents of the project site would attend Buena Vista Elementary, located approximately 0.9 miles southwest of the project site. During the academic year 2020-2021, Buena Vista Elementary School had an enrollment of 442 students.33 The school capacity is 495 students. Using WCSD’s generation rate of 0.0838 elementary school students per multi-family units, the proposed project would generate 11 elementary school students, which Buena Vista Elementary School would be able to accommodate.34 Middle school age residents of the project site would attend Walnut Creek Intermediate School, located approximately 1 mile southeast of the project site. During the academic year 2020-2021, Walnut Creek Intermediate School had an enrollment of 1,001 students.35 The school’s capacity is 1,038 students. Using WCSD’s generation rate of 0.0425 middle school students per multi-family unit, the proposed project would generate 6 additional students, which Walnut Creek Intermediate School would be able to accommodate.36 32 Walnut Creek School District, About Us.

During the academic year 2020-2021, Las Lomas High School had an enrollment of 1,580 students.37 FirstCarbon Solutions (FCS) sent a letter to Dr. J ohn Nickerson of the AUHSD on May 11, 2021, that included an inquiry about capacity of Las Lomas High School. To date, FCS has not received a response. Enrollment has held fairly steady at 1,530–1,580 for the past 5 years.38 If Las Lomas High School does not have sufficient capacity to support the new students generated by the proposed project, the students would be accommodated within the five other schools within the AUHSD. The project applicant would be required to pay development impact fees to the WCSD and AUHSD, which would assist to expand facilities to address increased demand. Pursuant to Government Code Section 65995, payment of adopted development fees is considered “full and complete mitigation” for impacts to school facilities, and local governments are prohibited from assessing additional fees or exactions for school impacts.39 With payment of impact fees to the WCSD and AUHSD, operation of the proposed project would not create a need to construct new or expand existing school facilities. Therefore, operational impacts related to need for new or altered school facilities impacts would be less than significant. Level of Significance Less than significant impact. Need for New or Altered Library Facilities Impact PUB-4: The proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered library facilities, need for new or physically altered library facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios or other performance objectives for library facilities. Construction Impacts related to provision of and need for construction of new or expanded library facilities are limited to operational impacts. No construction impacts would occur.

The General Plan does not include a standard or goal for the provision of library services; however, for informational purposes, the County generally provides approximately 319 gross square feet of library space per 1,000 residents.40 The proposed project’s approximately 357 residents is a nominal increase compared with the existing County population of approximately 1.1 million residents served by the Contra Costa County Library system. The proposed project’s estimated increase in persons would represent an increase of less than 1 percent relative to the existing residents served by the Contra Costa County Library system. As such, the County’s provision of library space per 1,000 residents would not be affected by implementation of the proposed project. Furthermore, the County Librarian anticipates that the proposed project would not have a noticeable effect on the ability of the County Library system to provide library services.41 With adequate relevant library system capacity, operation of proposed project would not create a need to construct new or expand existing library facilities. Therefore, operational impacts related to need for new or altered public library facilities would be less than significant. Level of Significance Less than significant impact. Effects of Increased Use of Existing Parks Impact REC-1: The proposed project would not increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated. Construction Impacts related to increased use of existing parks and recreational facilities are limited to operational impacts. No construction impacts would occur. Operation The DPR, EBRPD, Contra Costa County, and cities in the proposed project vicinity maintain State, regional, and local community parks, trails, and recreational facilities for public use throughout Contra Costa County. County park standards are established in the County’s General Plan. Specifically, Goal 9-K of the General Plan Open Space Element, seeks to achieve a level of park facilities equal to 4 acres per 1,000 population or 0.004-acre per person. With a County population of 1,153,854 persons (2021), and approximately 46,624 acres of parks (State, County, EBRPD, and local parks), the current ratio is approximately 40.4 acres per 1,000 population, far exceeding the County’s goal. The proposed 125 residential units would be expected to result in a permanent population of 357 persons, resulting in the need for 1.428 acres of parkland to assist in the County’s parkland goal. The proposed project would provide a central open space area, paseo and walkways, a dog park, and private yards. However, these facilities would be private and not available to the surrounding 40 Contra Costa County Library. 2006. New Strategic Plan. January 9. 41 McKee, Alison.

Besides the 32 local community parks located within 3 miles of the project site, Mount Diablo State Park is located approximately 5 miles southeast of the project site, Diablo Foothills Regional Park is located approximately 4.3 miles southeast of the project site, and Briones Regional Park is located approximately 3 miles west of the project site. These parks total nearly 7,000 acres in available existing parks. Given the wide range of proposed on-site and existing proximate parks and recreational facilities available to project-related residents, the recreational needs of the proposed project’s anticipated 357 new residents would be dispersed across these nearly 7,000 total acres of parkland and, thus, not result in an increased use that would cause substantial physical deterioration of existing neighborhood and regional parks or other recreational facilities. Additionally, the proposed project is subject to the County’s Park Impact Fee. The Park Impact Fees would be collected to fund the acquisition and development of parks in Contra Costa County to serve unincorporated County residents, in lieu of providing the required acreage on the project site.42 Therefore, impacts related to potential increased use and physical deterioration of existing parks and recreational facilities would be less than significant. Level of Significance Less than significant impact. Effects from Provision of Parks or Recreational Facilities Impact REC-2: The proposed project could include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment. Construction The proposed project would include approximately 2.1 acres (92,120 square feet) of private recreational facilities on the project site. The proposed project’s private recreational facilities would include a central open space area, paseo and walkways, a dog park, and private yards. The environmental impacts associated with implementation of these amenities is analyzed in the discussion of air quality, energy, GHG emissions, noise, and transportation-related impacts within this Draft Environmental Impact Report (Draft EIR), which are explained in more detail as follows: • Air Quality: Less than significant impact with mitigation incorporated. Impact AIR-3 relates to sensitive receptors. Receptors include residences, schools and schoolyards, parks and playgrounds, daycare centers, nursing homes, and medical facilities. Mitigation Measure (MM) AIR-2 and MM AIR-3 would reduce construction impacts to a less than significant level. 42 Contra Costa County Department of Conservation and Development. 2021.

Impact NOI-2 relates to construction noise and applicable standards and MM NOI-2 reduces impacts during construction to a less than significant level. • Transportation: Less than significant impact. Therefore, the proposed project’s construction of parks and recreational facilities on the project site would result in a less than significant impact with mitigation incorporated. Operation Impacts related to increased use of existing parks and recreational facilities are limited to construction impacts. No operational impacts would occur. Level of Significance Before Mitigation Potentially significant impact. Mitigation Measures Implement MM AIR-2, MM AIR-3, and MM NOI-2. Level of Significance After Mitigation Less than significant with mitigation. 3.13.5 - Cumulative Impacts The geographic scope of the cumulative public services and Recreation analysis is the service area of each of the providers serving the proposed project. Because of differences in the nature of the public service topical areas, they are discussed separately. The development projects listed in Table 3-1 are mostly industrial and commercial in nature. Of the projects listed in Chapter 3, Environmental Impact Analysis, Table 3-1, Projects 1, 2, 5, 6, and 9–23 are residential projects, most of which are located within the City of Pleasant Hill. As such, cumulative development could increase population within the proposed project vicinity by approximately 2,910 persons. The proposed project would add an estimated 357 persons to the County’s population. Fire Protection Facilities The geographical scope of the cumulative public services analysis is the boundaries of the CCCFPD. Other cumulative projects listed in Table 3-1 in conjunction with the proposed project would result in primarily residential and commercial development. Cumulative development in the surrounding area would be expected to substantially increase permanent residents and daytime population, which includes employees and visitors/patrons. The cumulative increase in population could in turn result in an increased demand for fire protection facilities. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Public Services and Recreation FirstCarbon Solutions 3.13-25 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-13 Public Services and Rec.docx To help offset the increased demand, the cumulative projects would be required to pay all applicable fees to the CCCFPD. All developments would also adhere to the California Fire Code, Part 9 of the CBC in terms of meeting standards for fire safety such as fire flow requirements for buildings, fire hydrant location and distribution criteria, automated sprinkler systems, and fire-resistant building materials. With adherence to CBC Code sections and payment of applicable fees, cumulative projects would not result in need for new or altered fire protection or emergency medical facilities. Thus, there would be a less than significant cumulative impact with regard to need for new or altered fire protection and emergency medical facilities. Police Protection Facilities The geographical scope of the cumulative public services analysis is the boundaries of the County Office of the Sheriff. Other cumulative projects listed in Table 3-1 in conjunction with the proposed project would result in primarily residential and commercial development. Cumulative development in the surrounding area would be expected to substantially increase permanent residents and daytime population, which includes employees and visitors/patrons. The cumulative projects listed in Table 3-1 total 1,020 residential units; accordingly, based on the California Department of Finance average household size of 2.85 persons, the estimated increase in persons would total approximately 2,910 persons and would represent an increase of 0.25 percent relative to current County population. The cumulative increase in population could in turn result in an increased demand for police protection facilities. To help offset the increased demand for police protection facilities, the cumulative projects would be required to pay applicable fees to the Office of the Sheriff. All developments would also be reviewed for impacts on law enforcement services and would be required to address any potential impacts with mitigation. Because demand for law enforcement services is highly dependent on a number of factors that vary substantially by project (clientele, hours of operation, crime prevention measures, etc.), it is unlikely that there would be substantial overlap in demand that would result in a cumulatively significant impact such that new police protection facilities are necessary. With payment of applicable fees, cumulative projects would not result in need for new or altered police protection facilities. Thus, there would be a less than significant cumulative impact with regard to need for new or altered police protection facilities. School Facilities The geographical scope of the cumulative public services analysis is the boundaries of the WCSD and AUHSD. Other cumulative projects listed in Table 3-1 in conjunction with the proposed project would result in residential development. Cumulative development would increase the population and demand for educational facilities. The cumulative projects listed in Table 3-1 total 1,020 residential units; accordingly, based on the Department of Finance average household size of 2.85 persons, the estimated increase in persons would total approximately 2,910 persons and would represent an increase of 0.25 percent relative to current County population. The cumulative increase in population could in turn result in an increased demand for school facilities. Contra Costa County–Oak Road Townhouse Condominiums Project Public Services and Recreation Draft EIR 3.13-26 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-13 Public Services and Rec.docx Other cumulative projects do not include any educational facilities. All cumulative developments would be required to pay development impact fees impact fees toward the two applicable school districts. Under State law, this is the exclusive means of mitigating impacts to school facilities due to increased enrollment. As part of the project entitlement process, the cumulative project applicants would be responsible for paying their fair share of these school facility fees. With payment of impact development fees, cumulative projects would not result in need for new or altered school facilities. Thus, there would be a less than significant cumulative impact with regard to need for new or altered school facilities. Library Facilities The geographic scope of the cumulative library facilities analysis is the County Library system. Other cumulative projects listed in Table 3-1 in conjunction with the proposed project would result in residential development. Cumulative development would increase the population and demand for library facilities. The cumulative projects listed in Table 3-1 would total 1,020 residential units; accordingly. Based on the Department of Finance average household size of 2.85 persons, the cumulative projects listed in Table 3-1 would result in an increase of approximately 2,910 persons, and in addition to the project’s estimated increase of 357 persons, would represent a total cumulative increase of approximately 3,267 persons. This would represent a cumulative population increase of 0.28 percent relative to the 2018 estimate. The cumulative increase in population could in turn result in an increased demand for library facilities. The County generally provides approximately 319 gross square feet of library space per 1,000 residents. With development of the other cumulative project in conjunction with the proposed project, the County’s provision of library space per 1,000 residents would need to be increased by approximately 1,042 square feet. The construction of the new Pleasant Hill Library (scheduled to be completed in 2022) would more than adequately address this need. Therefore, cumulative projects would not result in need for new or altered library facilities. Thus, there would be a less than significant cumulative impact with regard to need for new or altered library facilities. Increased Park Use The geographic scope of the cumulative parks and recreation analysis consists of the local community, regional, and State parks within the boundaries of Contra Costa County, the City of Pleasant Hill, and the City of Walnut Creek with a focus on the areas of unincorporated Contra Costa County near where the project site is located. These include parks and recreational facilities managed by the DPR, EBRPD, City of Walnut Creek, and Pleasant Hill Recreation and Park District. The proposed project in conjunction with the cumulative projects listed in Chapter 3, Environmental Impact Analysis, Table 3-1, Cumulative Projects, would result in many residential developments in the proposed project area. Cumulative development in the proposed project area would be expected to increase permanent residents by a approximately 2,910 persons, in addition to the proposed project’s estimated increase of 357 for a total increase of approximately 3,267. This increase in permanent population would result in an increased cumulative demand for park facilities.

The Park Impact Fees would be collected to fund the acquisition and development of parks in Contra Costa County to serve unincorporated County residents, in lieu of providing the required acreage on the project site. Other projects listed in Table 3-1 that are within the City of Walnut Creek and City of Pleasant Hill would similarly be required to provide parkland or pay development fees. With payment of Park Impact Fees by the cumulative projects, there would be a less than significant cumulative impact related to potential increased use and physical deterioration of existing parks and recreational facilities. The DPR, EBRPD, Contra Costa County, and cities in the proposed project vicinity maintain State, regional, and local community parks, trails, and recreational facilities for public use throughout Contra Costa County. County park standards are established in the County’s General Plan. Specifically, Goal 9-K of the General Plan Open Space Element, seeks to achieve a level of park facilities equal to 4 acres per 1,000 population or 0.004-acre per person. With a County population of 1,153,854 persons (2021), and approximately 46,624 acres of parks (State, County, various cities, and EBRPD), the current ratio is approximately 40.4 acres per 1,000 population, far exceeding the County goal. The cumulative projects would add approximately 2,910 residents to the area. However the current high ratio of parks to population would not be significantly impacted by the added residents. Level of Cumulative Significance Less than significant impact.

This section also evaluates the possible impacts related to transportation that could result from implementation of the project. Information in this section is based on the project-specific Transportation Analysis prepared by Hexagon Transportation Consultants Inc.1 The complete report is included as Appendix I. During the Notice of Preparation (NOP) comment period, the fol lowing comments were received related to the proposed project regarding transportation: • If the proposed project meets the screening criteria to be exempt from detailed Vehicle Miles Traveled (VMT) analysis, requests justification to support the exempt status in line with the City’s VMT policy. • If the proposed project does not meet exempt screening criteria, list the required components for the VMT analysis in the Environmental Impact Report (EIR). • Offered mitigation strategies such as Transportation Demand Management (TDM) Program. • Requested identification of project-generated travel demand and cost estimate transportation improvements necessitated by the proposed project as well as viable funding sources. • Stated that the County is responsible for all project mitigation. • Stated requirements associated with equitable access including Americans with Disabilities Act (ADA) Standards and bicycle and pedestrian access during construction. • Stated that an Encroachment Permit may be required and lists the submittal requirements. • Concerns regarding traffic congestion due to the proposed project. • The proposed project would result in permanent negative impact on traffic patterns. • The proposed project would exacerbate current congestion at the Treat Boulevard intersection. • The proposed project would result in more vehicles than the project site previous use. 3.14.2 - Existing Conditions Roadway Network The following discusses the existing roadways that provide access to the project site and vicinity. The existing roadway network is shown on Exhibit 3.14-1. 1 Hexagon Transportation Consultants, Inc. 2021.

I-680 primarily runs north/south connecting Contra Costa County (County) to regional destinations such as San José to the south and Fairfield to the north. I-680 is located west of the project site and can be accessed via the Treat Boulevard interchange. In the project site vicinity, this freeway provides five mixed-flow and one high-occupancy vehicle lane in the southbound direction, and five mixed-flow lanes in the northbound direction, in addition to auxiliary lanes between interchanges. Approximately 260,000 vehicles per day travel on I-680 at the Treat Boulevard interchange. Access to/from northbound I-680 in the project site vicinity is provided from on-ramps on either Buskirk Avenue or Oak Road. Access to/from southbound I-680 is provided from N. Main Street at Sunnyvale Avenue. I-680 is a designated Route of Regional Significance. Treat Boulevard Treat Boulevard is an east–west arterial that extends east from North Main Street to Clayton Road, connecting Walnut Creek and Concord, and is located north of the project site. West of North Main Street, Treat Boulevard becomes Geary Road. Off-ramps from northbound I-680 connect to the intersection of Treat Boulevard and Buskirk Avenue. Westbound Treat Boulevard provides access to northbound I-680 via the Buskirk Avenue onramp. Eastbound Treat Boulevard provides access to southbound I-680 via an onramp just east of North Main Street. Within the project site vicinity, Treat Boulevard provides three travel lanes in the westbound direction and four travel lanes in the eastbound direction, with additional turn pockets at intersections. On-street parking is only allowed on westbound Treat Boulevard between Jones Road and Oak Road. The posted speed limit is 35 miles per hour. Sidewalks are provided on both sides of the roadway, except for the small eastbound portion between North Main Street and Buskirk Avenue. Treat Boulevard is a designated Route of Regional Significance. Oak Road Oak Road is a north–south roadway with two lanes in each direction and a center two-way left turn lane that forms the eastern boundary of the project site. The roadway serves as a parallel route to I- 680 between Walnut Creek and Pleasant Hill. Sidewalks are provided on both sides of the roadway. The posted speed limit varies between 30 and 35 miles per hour. The Contra Costa Canal Trail, a Class I regional trail, intersects Oak Road at a signalized crossing approximately 450 feet south of the project site. Jones Road Jones Road is north–south collector with one lane in each direction that connects Parkside Drive and the Pleasant Hill/Contra Costa Centre Bay Area Rapid Transit (BART) station. Jones Road provides driveway access to the project site. The roadway serves as a parallel route to I-680 between Walnut Creek and Pleasant Hill. An existing sidewalk is provided on the east side of Jones Road. There are no designated bicycle facilities on Jones Road. The Contra Costa Canal Trail intersects Jones Road at an unsignalized crossing approximately 600 feet south of the project site. Study Intersections and Data Collection Hexagon conducted AM and PM peak period traffic counts on February 4, 2021, at the following study intersections: Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Transportation FirstCarbon Solutions 3.14-3 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-14 Transportation.docx 1. Oak Road and Jones Road 2. Oak Road and Treat Boulevard 3. Jones Road and Project Driveway 4. Oak Road and Project Driveway Note that the traffic volumes collected are adjusted to pre-COVID conditions. The intersection at Oak Road and Treat Boulevard had historic counts in year 2018. A factor was derived by comparing the historic counts to the newly collected (2021) counts. This factor was applied to all other intersections to derive pre-COVID volume estimates. Since the pre-COVID count was dated for year 2018, Hexagon derived an annual growth rate using counts at this intersection collected in 2014. This annual growth rate was then applied to all intersection volumes to bring the 2018 counts/derived volumes to 2021 conditions as if there was no COVID (see Table 3.14-1 for calculations of COVID factors, Table 3.14-2 for calculations of growth rates and Table 3.14-3 for a comparison). This represents a conservative analysis. Further factoring were conducted at the Oak Road and Jones Road intersection to ensure volume balancing on the north leg with the intersection at Oak Road and Treat Boulevard. The existing school driveway traffic volumes were estimated based on the trip rates published in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 10th Edition (2017) for Private School (K-8). The Oak Road/Project Driveway traffic volumes were taken from the Oak Road/Jones Road intersection. Exhibit 3.14-2 shows the existing traffic volumes at the study intersections.

Bicycle Facilities The California Department of Transportation (Caltrans) Highway Design Manual and National Association of City Transportation Officials Urban Bikeway Design Guide define four major types of bicycle facilities: • Class I: Multiuse Path—These paths provide a completely separate right-of-way and are designated for the exclusive use of bicycles and pedestrians with vehicle crossflow minimized. • Class II: Bicycle Lane—These bicycle lanes provide a restricted right-of-way and are designated for the use of bicycles for one-way travel with a striped lane on a street or highway. These bicycle lanes are generally a minimum of 5 feet wide, and vehicle/pedestrian crossflow is permitted. • Class III: Bicycle Route with Sharrows—These bikeways provide right-of-way designated by signs or pavement markings for shared use with motor vehicles. These bikeways include sharrows or “shared-lane markings” to highlight the presence of bicyclists. • Class IV: Separated Bicycle Lanes—These bicycle lanes consist of a physically separate lane for increased comfort and protection of bicyclists. These bicycle lanes can be physically separated by a barrier, such as planters or on-street parking, grade-separated from the roadway, or a painted buffer area. These can also be called cycle tracks, and can allow for one-way or two- way bicycle travel.

The Iron Horse Trail extends in a north–south direction from Concord to Pleasanton, while the Contra Costa Canal Tra il meanders in a general horseshoe shape, traversing from Martinez in the west through Pleasant Hill and Walnut Creek before turning north toward Concord. The Contra Costa Canal Trail is located approximately 450-600 feet south of the project site. The two trails intersect approximately 900 feet east of the project site. The Class II bike lanes on Oak Road extend from the Contra Costa Canal Trail to Walden Road. There are no existing bike facilities on Jones Road. Pedestrian Facilities Pedestrian facilities include sidewalks, pathways, crosswalks, and pedestrian signals. Sidewalks exist on both Jones Road and Oak Road along the project frontage. Public Transit The project site is located within 0.5 mile of a major transit stop, the Pleasant Hill/Contra Costa Centre BART station, which is located north of the project site. Bus transit services in the vicinity of the project site are provided by several transit providers, connecting at this station. County Connection operates weekday bus routes 7, 9, 11, 14, 15, and 18; weekend bus routes 311 and 316; and Early Bird Express routes 702 and 712. In addition, Solano Express operates their Blue and Yellow lines, Fairfield and Suisun Transit (FAST) operates their Blue line, Wheels Bus operates line 70X, and Alameda-Contra Costa Transit District (AC Transit) operates route 702.2,3 The closest bus stop to the project site is located at Oak Road and Walden Park, approximately 970 feet south of the project site and another at Charter Oak Circle, a short distance away. There are sidewalks on Oak Road that provide connectivity to the bus stop. 3.14.3 - Regulatory Framework Federal No federal plans, policies, regulations, or laws related to transportation are applicable to the proposed project. State California Department of Transportation Level of Service Goals Caltrans builds, operates, and maintains the State highway system, including the interstate highway system. Caltrans’s mission is to improve mobility Statewide. The department operates under strategic goals to provide a safe transportation system, optimize throughput, and ensure reliable travel times, improve the delivery of State highway projects, provide transportation choices, and improve and enhance the State’s investments and resources. Caltrans controls the planning of the State highway system and accessibility to the system. Caltrans requires encroachment permits from agencies or new 2 Bay Area Rapid Transit (BART). 2019.

For projects that would impact traffic flow and levels of services on State highways, Caltrans would review measures to mitigate the traffic impacts. However, Caltrans has adopted the 2013 Contra Costa Transportation Authority (CCTA ) Congestion Management Plan (CMP) standards, which are the criteria used to identify impacts in the project-specific Traffic Impact Analysis (TIA) and this Draft EIR. Senate Bill 743 In November 2017, the Governor’s Office of Planning and Research (OPR) released a technical advisory containing recommendations regarding the assessment of VMT, proposed thresholds of significance, and potential mitigation measures for lead agencies to use while implementing the required changes contained in Senate Bill (SB) 743, which was passed in 2013 (Steinberg). Also in November 2017, OPR released the proposed text for Section 15064.3, “Determining the Significance of Transportation Impacts,” which summarized the criteria for analyzing transportation impacts for land use projects and transportation projects and directs lead agencies to “choose the most appropriate methodology to evaluate a project’s VMT, including whether to express the change in absolute terms, per capita, per household or in any other measure.” OPR recommends that for most instances a per service population threshold should be adopted and that a 15 percent reduction below that of existing development would be a reasonable threshold. As noted in the OPR Guidelines, agencies are directed to choose metrics that are appropriate for their jurisdiction to evaluate the potential impacts of a project in terms of VMT. The current deadline for adopting policies to implement SB 743 is July 2020; the change to VMT was formally adopted as part of updates to the California Environmental Quality Act (CEQA) Guidelines in December 2018. VMT has been identified as the most appropriate metric to evaluate a project’s transportation impacts, as projects that result in lower-than-average VMT support goals of reducing greenhouse gas emissions, while projects that result in higher-than-average levels of vehicle travel contribute to an increasing rate of greenhouse gas emissions. The County’s Transportation Analysis Guidelines (TAGs) were adopted by the County Board of Supervisors on June 23, 2020. The TAG establishes VMT thresholds in the unincorporated areas of the County. Projects that are within 0.5-mile of an existing major transit stop, which is defined as a rail transit station, ferry terminal served by bus or rail transit, or at the intersection of two or more major bus routes with service frequencies of 15-minutes or less during the morning and afternoon peak commute periods, are presumed to be less than significant if the project has the following characteristics: • Has a floor area ratio (FAR) greater than 0.75. • Does not include more parking for use by residents, customers, or employees of the project than required by the jurisdiction (if the jurisdiction requires the project to supply parking). • Is consistent with the applicable Sustainable Communities Strategy (as determined by the lead agency, with input from the Metropolitan Planning Organization). • Does not replace affordable residential units with a smaller number of moderate or high- income residential units.

Since there are no standards in effect on VMT analysis, a preliminary assessment of the VMT generated by the project was prepared for informational and disclosure purposes only. No determination on the significance of VMT impacts is made in this document since none is legally required. Regional Contra Costa Transportation Authority – Central County Action Plan CCTA is the Congestion Management Agency for the County. CCTA implements the Central County Action Plan, which sets forth performance objectives for Routes of Regional Significance. Treat Boulevard (including one of the study intersections on this roadway) is a Route of Regional Significance. Local Contra Costa County Transportation Analysis Guidelines The County has adopted VMT-based thresholds for the evaluation of CEQA impacts to the transportation system, which are documented in the Contra Costa County TAGs.4 The TAGs identify VMT Screening Criteria, VMT Metrics, VMT Forecasting, VMT Thresholds, and VMT Mitigation. Contra Costa County General Plan Transportation and Circulation Element The Transportation and Circulation Element includes fundamental concepts that shape the element and support a “well-planned and integrated multimodal transportation network.”5 The following are fundamental concepts recognized in developing the Transportation and Circulation Element: • Improving the quality, safety, and reliability of transit, walking, and bicycle facilities in the County will both allow and encourage greater use of these alternatives. • Streets should be designed and maintained according to the “Complete Streets” philosophy. The General Plan sets forth the following goals and policies that are relevant to transportation: Goal 5-A To provide a safe, efficient, and integrated multimodal transportation system. Goal 5-C To balance transportation and circulation needs with the desired character of the community. Goal 5-D To maintain and improve air quality above air quality standards. Goal 5-E To permit development only in locations of the County where appropriate traffic level of service standards are ensured. 4 Contra Costa County. 2020.

Contra Costa Countywide Bicycle and Pedestrian Plan To support and encourage walking and bicycling in the County, the CCTA, on July 18, 2018, adopted the 2018 Contra Costa Countywide Bicycle and Pedestrian Plan (CBPP).6 (The CCTA adopted its first CBPP in 2003 and updated it in 2009). The CBPP builds on and expands the goals, policies, and strategies of the CCTA’s Comprehensive Transportation Plan (CTP). Both plans set goals for increasing walking and bicycling and identify actions the Authority and its partners should take to achieve them. Complete Streets Policy of Contra Costa County The Complete Streets Policy was adopted by Resolution No. 2016/374 by the Board of Supervisors of the County on July 12, 2016. A. Complete Streets Principles 1. Complete Streets Serving All Users. Contra Costa County expresses its commitment to creating and maintaining Complete Streets that provide safe, comfortable, and convenient travel along and across rights-of-way (including streets, roads, highways, bridges, paths, and other portions of the transportation system) through a comprehensive, integrated transportation network that serves all categories of users, including pedestrians, bicyclists, persons with disabilities, motorists, movers of commercial goods, users and operators of public transportation, seniors, children, youth, students and families. 2. Context Sensitivity. In planning and implementing street projects, departments and agencies of Contra Costa County shall maintain sensitivity to local conditions in both residential and business districts as well as urban, suburban, and rural areas, and shall work with residents, merchants, school representatives, and other stakeholders to ensure that a strong sense of place ensues. Improvements that will be considered include sidewalks, shared use paths, separated bikeways/cycle tracks, bicycle lanes, bicycle routes, paved shoulders, street trees and landscaping, planting strips, accessible curb ramps, crosswalks, refuge 6 Contra Costa Transportation Authority (CCTA). 2019.

Complete Streets Routinely Addressed by All Departments. All departments and agencies of Contra Costa County shall work toward making Complete Streets practices a routine part of everyday operations, approach every relevant project, program, and practice as an opportunity to improve streets and the transportation network for all categories of users/modes, and work in coordination with other departments, agencies, and jurisdictions to maximize opportunities for Complete Streets, connectivity, and cooperation. Example activities include, but are not necessarily limited to the following: pavement resurfacing, restriping, accessing above and underground utilities, signalization operations or modifications, maintenance of landscaping/related features, and shall exclude minor (catch basin cleaning, sign replacement, pothole repair, etc.) maintenance and emergency repairs. 4. All Projects and Phases. Complete Streets infrastructure sufficient to enable reasonably safe travel along and across the right-of-way for each category of users shall be incorporated into all planning, funding, design, approval, and implementation processes for any construction, reconstruction, retrofit, maintenance, operations, alteration, or repair of streets (including streets, roads, highways, bridges, and other portions of the transportation system), except that specific infrastructure for a given category of users may be excluded if an exemption is approved via the process set forth in Section C.1 of this policy. B. Implementation 1. Plan Consultation and Consistency. Maintenance, planning, and design of projects affecting the transportation system shall be consistent with the Contra Costa County General Plan, as well as other applicable bicycle, pedestrian, transit, multimodal, best practices, and other relevant documents. Where such consistency cannot be achieved without negative consequences, consistency shall not be required if the head of the relevant departments, or designees, provides written approval explaining the basis of such deviation. 2. Street Network/Connectivity. As feasible, and as opportunities arise, Contra Costa County shall incorporate Complete Streets infrastructure into existing streets to improve the safety and convenience of users, with the particular goal of creating a connected network of facilities accommodating each category of users, increasing connectivity across jurisdictional boundaries, and for accommodating existing and anticipated future areas of travel origination or destination. A well-connected network should include non-motorized connectivity to schools, parks, commercial areas, civic destinations, and regional non-motorized networks on both publicly owned roads/land and private developments (or redevelopment areas). 3. Countywide Bicycle Advisory Committee (CBAC) Consultation. The CBAC may review the design principles used by staff to accommodate motor vehicle, Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Transportation FirstCarbon Solutions 3.14-11 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-14 Transportation.docx bicycle, pedestrian, and transit modes of travel when reviewing projects. The CBAC will be engaged early in the planning and design stage to provide an opportunity for comments and recommendations regarding Complete Street features of major public transportation projects. 4. Evaluation. The County will establish a means to collect data and evaluate the implementation of complete streets policies. For example, tracking the number of miles of paths, bike lanes and sidewalks, numbers of street crossings, signage etc. C. Exceptions 1. Required Findings and Leadership Approval for Exemptions. Plans or projects that seek exemptions from incorporating Complete Streets design principles must provide a written explanation of why accommodations for all modes were not included in the project. An exemption may be granted by the Director of Public Works or Director of Conservation and Development upon finding that inclusion of Complete Streets design principles are not possible or appropriate under one or more of the following circumstances: (1) bicycles or pedestrians are not permitted on the subject transportation facility pursuant to State or local laws; (2) inclusion of Complete Streets design principles would result in a disproportionate cost to the project; (3) there is a documented absence of current and future need and demand for Complete Streets design elements on the subject roadway; and, (4) one or more significant adverse effects would outweigh the positive effects of implementing Complete Streets design elements. Plans or projects that are granted exceptions must be made available for public review. Contra Costa County Ordinance Code Chapter 82-16.412 of the Contra Costa County Ordinance Code (Ordinance Code) sets forth the amounts of long-term and short-term bicycle parking that a project must provide. The Ordinance Code requires a multiple-family dwelling with a parking garage to provide space for 5 percent of the number of bedrooms for short-term parking, or two spaces (whichever is greater). Long-term parking is not required.7 3.14.4 - Methodology Hexagon Transportation Consultants, Inc. prepared a Transportation Analysis for the proposed project. The complete report is provided in Appendix I. The methodology of the analysis is described as follows. Project Trip Estimates The magnitude of traffic produced by a new development and the locations where that would appear are estimated using a three-step process: (1) trip generation, (2) trip distribution, and (3) trip 7 Contra Costa County Ordinance Code. 2018.

In determining project trip generation, the magnitude of traffic entering and exiting the site is estimated for the AM and PM peak-hours. As part of the project trip distribution, an estimate is made of the directions to and from which the project trips would travel. In the project trip assignment, the project trips are assigned to specific streets and intersections. These procedures are described below. Project Trip Generation Vehicle trips generated by the proposed residential component of the project were estimated using the trip rates published in the ITE Trip Generation Manual, 10th Edition (2017) for “Single-Family Detached Housing” (Land Use 210). Since the proposed units all include at least three bedrooms with their own attached garages, it was determined that the single-family detached housing land use would best reflect the trip generation characteristic for the proposed project. It should be noted that the single-family rates are also the highest trip generation rates out of all residential trip rates. This analysis thus represents a slightly conservative analysis. As shown in the Table 3.14-4, the proposed project is estimated to generate 1,180 gross daily vehicle trips, with 93 gross trips occurring during the AM peak-hour and 124 gross trips during the PM peak-hour.

Existing Trip Credits Trips generated by the existing uses on the site can be credited against the proposed development. At the time of this report, the former private school is permanently closed. However, the school is being credited, pursuant to North County Advocates v. City of Carlsbad, 241 Cal.App.4th 94 (2015), because this traffic study is analyzed under pre-COVID conditions when the school was open. The existing baseline traffic counts, as discussed earlier, are all factored to pre-COVID conditions. The private school trip generation estimates are based on ITE rates for Private School (K-8). According to the former school owner, the school had student enrollments ranging between 370 Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Transportation FirstCarbon Solutions 3.14-13 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-14 Transportation.docx students and 400 students. The school also had after-school activities and was open until 6:00 p.m. on school days. For a conservative analysis, the school is credited using the 370 students. When comparing the PM peak-hour rate to other private/charter elementary and middle schools (average of 0.56 trips per student), the ITE rate of 0.26 trips per student for the PM peak-hour appeared low. Table 3.14-5 provides a PM peak-hour trip rate of elementary and middle schools similar to the existing school. Therefore, crediting school’s PM trip generation using the ITE trip rates represent a conservative analysis. It is estimated that the private school with 370 students would have generated 1,521 daily trips with 337 trips during the AM peak-hour and 96 trips during the PM peak-hour.

It should be noted that this analysis represented a conservative analysis. Crediting the project with even the lowest observed PM rates for comparable schools would have resulted in an overall net decrease in trips.

The peak-hour trips generated by the existing and proposed uses were assigned to the roadway system based on the directions of approach and departure, the roadway network connections, and the locations of project driveways. The trips generated by the existing uses were subtracted from the roadway network prior to assigning project trips. It should be noted that the school trips were only accessed on one driveway on Jones Road. It is assumed that all residential trips would enter and exit the project site via two driveways each on Jones Road and on Oak Road. Exhibit 3.14-3 shows the trip distribution and assignment of the proposed project. 3.14.5 - Significance Criteria According to CEQA Guidelines Appendix G Environmental Checklist, to determine whether transportation and traffic impacts are significant environmental effects, the following questions are analyzed and evaluated. Would the project: a) Conflict with a program plan, ordinance, or policy of the circulation system, including transit, roadway, bicycle, and pedestrian facilities? b) Would the project conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b)? c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? d) Result in inadequate emergency access? 3.14.6 - Project Impacts and Mitigation Measures This section discusses potential impacts associated with the proposed project and provides mitigation measures where necessary. Impact Evaluation Circulation System Impact TRANS-1: The proposed project would not conflict with a program plan, ordinance or policy of the circulation system, including transit, roadway, bicycle and pedestrian facilities? Bicycle Facilities Currently, there are no existing bike lanes on Jones Road. However, there is a pedestrian/bike trail, Iron Horse Regional Trail, located approximately 1,500 feet east of the project site. The bike trail provides access to the Pleasant Hill/Contra Costa Centre BART station. There is also another pedestrian/bike trail, Contra Costa Canal Trail, located approximately 450–600 feet south of the project site and crossing Oak Road and Jones Road. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. The project would not affect existing or planned bicycle facilities. The project also proposes to Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Transportation FirstCarbon Solutions 3.14-15 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-14 Transportation.docx include a bike repair space on-site. The Seven Hills School is located within a 3-mile radius of the project site. The Contra Costa Canal Trail provides a good bicycle connectivity to the project site and the Seven Hills School. Oak Road has planned Class II facilities in the vicinity of the project. The planned Class facilities is located on Oak Road between Treat Boulevard and the Contra Costa Canal Trail. The four on-street parking spaces proposed along Oak Road would not result in a conflict with future construction of this facility. The Iron Horse Regional Trail, a pedestrian/bike trail, located approximately 1,500 feet east of the project site. The Iron Horse Regional Trail extends from Marsh Drive in Concord to Santa Rita Road in Pleasanton. The Iron Horse Regional Trail provides access to the Pleasant Hill/Contra Costa Centre BART station. There is also another trail, Contra Costa Canal Trail, located approximately 650 feet south of the project site and crossing Jones Road. The Contra Costa Canal Trail extends from Muir Road in Martinez to Willow Pass Road in Concord. The Contra Costa Canal Trail provides access to Walden Park and the Iron Horse Regional Trail. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat B oulevard and Walden Road. Exhibit 3.14-4 shows the existing bicycle facilities within the project area. The proposed project would include bicycle parking and a bicycle repair station on-site. Pedestrian Facilities There are sidewalks on the east side of Jones Road within the vicinity of the project site. There are also sidewalks on both sides of Oak Road and Treat Boulevard so that residents at the project site can easily walk to the Pleasant Hill/Contra Costa Centre BART station. The traffic signals at the Oak Road/Jones Road and Oak Road/Treat Boulevard intersections include crosswalks with pedestrian signal heads to facilitate crossing the street. The Iron Horse Regional Trail and Contra Costa Canal Trial described previously are Class I pedestrian/bicycle facilities within project proximity. There are no pedestrian improvement plans along Jones Road or Oak Road along the project frontage, and the project would not affect existing or planned pedestrian facilities. The Seven Hills School is located within a 1-mile radius of the project site, and the Contra Costa Canal Trail provides a pedestrian connection to the school from the project site. Transit Facilities The site is served by several County Connection bus routes: 7, 9, 11, 14, 15, and 311. The project site is located with 0.5 mile of a major transit stop, the Pleasant Hill/Contra Costa Centre BART station, which is located north of the project site. The closest bus stop to the project site is located at Oak Road and Walden Park, approximately 970 feet south of the project site. There are sidewalks on Oak Road that provide connectivity to the bus stop. The Pleasant Hill/Contra Costa Centre BART station also provides other bus route connections in addition to other County Connection lines. AC Transit, Solano Express, FAST, and Wheels Express provide connecting transit routes at the Pleasant Hill/Contra Costa Centre BART station (refer to Exhibit 3.14-5 and Table 3.14-6). Paratransit services could also be provided to the residents at the project site. County Connection LINK serves Pleasant Hill, Walnut Creek, Concord, Lafayette, and other central Contra Costa cities. Paratransit service rides are provided within 1.5 miles of a bus stop or train station.

In December 2018, the California Natural Resources Agency certified and adopted the CEQA Guidelines update package, including the Guidelines section implementing SB 743. The Guidelines state that Level of Service (LOS) will no longer be considered an environmental impact under CEQA and that VMT is the most appropriate measure of transportation impact. SB 743 went into effect on July 1, 2020. In accordance with new CEQA Guidelines, the County has transitioned from intersection LOS to VMT for CEQA transportation analysis. A project’s VMT is compared to the appropriate thresholds of significance based on the project location and type of development. When assessing a residential project, the project’s VMT is divided by the number of residents expected to occupy the project to determine the VMT per capita. To determine whether a project would result in CEQA transportation impacts related to VMT, the County has established thresholds for residential, office, and retail projects. For residential projects, the VMT threshold of significance is 85 percent of existing Countywide average VMT per capita. VMT Screening Criteria The County TAG also include screening criteria for projects that are expected to result in less than significant VMT impacts. These screening criteria are generally based on project size and location, as listed below: • Projects that: - Generate or attract fewer than 110 daily vehicle trips; or, - Projects of 10,000 square feet or less of non-residential space or 20 residential units or less, or otherwise generating less than 836 VMT per day. • Residential, retail, office projects, or mixed-use projects proposed within 0.5 mile of an existing major transit stop or an existing stop along a high-quality transit corridor. • Residential projects (home-based VMT) at 15 percent or below the baseline Countywide home-based average VMT per capita, or employment projects (employee VMT) at 15 percent or below the baseline Bay Area average commute VMT per employee in areas with low VMT that incorporate similar VMT reducing features (i.e., density, mix of uses, transit accessibility). • Public facilities (e.g., emergency services, passive parks (low-intensity recreation, open space), libraries, community centers, public utilities) and government buildings. Project-level VMT Analysis According to the County TAG , a project is expected to result in a less than significant VMT impact if the proposed project is located within 0.5 mile of an existing major transit stop or an existing stop along a high-quality transit corridor. The Pleasant Hill/Contra Costa Centre BART station is located within 0.5ile of the project site. In addition, there are bicycle and pedestrian facilities between the project site and the Pleasant Hill/Contra Costa Centre BART station, such as continuous sidewalks along Jones Road and Oak Road that connects to the project site to this BART station. At a normal walking pace, it would take approximately 5minutes to walk from the project site to this BART station.

There are also bike racks and bike lockers at the BART station for bicyclists to park their bicycles. Furthermore, the BART system provides quality regional connection to major employment destinations within the Bay Area (i.e., Oakland, San Francisco), and will soon connect to the San José area as well. The Pleasant Hill/Contra Costa Centre BART station also connects to local bus routes that are provided by County Connection. These local bus routes include County Connection weekday routes 7, 9, 11, 14, 15, and 18, County Connection weekend routes 311 and 316, County Connection Early Bird Express routes 702 and 712, Solano Express Blue and Yellow lines, FAST Blue line, Wheels Bus line 70X, and Alameda-Contra Costa Transit District (AC Transit) route 702. The regional transit connectivity available to the project residents, along with availability of bicycle parking on-site and bicycle and pedestrian facilities in the vicinity of the project site, would reduce residents’ need to drive. Therefore, the project’s VMT impact is considered less than significant. Level of Significance Less than significant impact. Although a formal TDM plan is not required for reducing VMT for the proposed project, the following measures are recommended to facilitate further VMT reductions and the use of alternate transportation modes as required by Ordinance Code 82-32.010.8 • Designate a Transportation Coordinator • Provide an online Kiosk/TDM Information Board • Provide Transportation Information Packets • Provide access to transit services and transit resources • Provide Bicycle Parking and Bicycle resources such as maps and bicycle safety tips • Provide information on Carpool and Vanpool programs Roadway Safety Hazards Impact TRANS-3: The proposed project would not substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment). Site Circulation and Access A review of the project site plan was performed to determine whether adequate site access and in- site circulation would be provided, using commonly accepted transportation planning principles and traffic engineering standards. Site Access Vehicle site access was evaluated to determine the adequacy of the site driveways. The project- generated traffic would access the site via a new driveway connecting to Jones Road. There would also be a proposed driveway that would connect to the project site on Oak Road. The new driveway 8 Contra Costa County Ordinance Code.

Sight Distance Sight distance was evaluated to determine whether a driver would have adequate visibility to enter Jones Road and Oak Road from the driveways. The project access points would remain free and clear of any obstructions that would materially and adversely affect sight distance, thereby ensuring that exiting vehicles can see pedestrians on the sidewalk and other vehicles traveling on adjacent roadways. As designed, landscaping and parking would not conflict with a driver’s ability to locate a gap in traffic and see oncoming pedestrians and bicyclists. Adequate corner sight distance (sight distance triangles) would be provided at all site access points in accordance with the County standards. Sight distance requirements vary depending on the roadway speeds. The speed limit on Jones Road and Oak Road is 35mph. According to the Highway Design Manual (HDM), Chapter 200, 2014, the required minimum stopping sight distance for design speed of 35 mph is 250 feet. The line of sight for vehicles exiting the driveway and vehicles traveling northbound on Jones Road are clear and visible. Vehicles exiting the driveway would be visible to the vehicles traveling southbound on Jones Road and Oak Road. There are existing red curbs on both sides of each driveway to provide adequate visibility for vehicles exiting the project site. The project would not substantially increase hazards due to any design features. On-site Circulation On-site circulation was reviewed in accordance with generally accepted traffic engineering standards. The project would provide new streets and alleys within the project site that lead to each unit. Each unit would have its own driveway and a garage. According to the Ordinance Code, the minimum two-way drive aisle width for multi-family uses is 20 feet and 26 feet when portion of the building has human occupancy located more than 30 feet above the access road. The site plan shows the appropriate drive aisle widths within the project site. The site plan would provide adequate space for garbage trucks, loading trucks and emergency vehicles to circulate throughout the project site. Level of Significance Less than significant impact. Emergency Access Impact TRANS-4: The proposed project would not result in inadequate emergency access. Emergency vehicle access would be provided via the two proposed driveways on Jones Road and Oak Road. The new driveway on Jones Road would be 26 feet wide, which can accommodate two-way traffic. The site plan shows that the Oak Road driveway would be approximately 26 feet wide. The two 26-foot-wide driveways would provide adequate access for emergency vehicles. As such, impacts would be less than significant. Level of Significance Less than significant impact.

This section also evaluates the possible impacts related to such utilities and service systems that could result from implementation of the proposed project. Descriptions and analysis in this section is based on information provided by the Contra Costa Water District (CCWD), CCWD 2015 Urban Water Management Plan (UWMP), West County Wastewater District (WCWD), California Department of Resources Recycling and Recovery (CalRecycle), and the Contra Costa County General Plan (General Plan). Information in this section is also based, in part, on the site-specific Stormwater Control Plan and Preliminary Hydrology and Hydraulics Calculations prepared by Ruggeri- Jensen-Azar (included in Appendix G). No public comments were received during the Draft Environmental Impact Report (Draft EIR) scoping period related to utilities and service systems. 3.15.2 - Environmental Setting Water CCWD provides potable water service to approximately 500,000 persons in central and northeastern Contra Costa County. CCWD’s treated water service area includes all or portions of the cities of Clayton, Concord, Martinez, Pleasant Hill, and Walnut Creek as well as nearby unincorporated areas of Contra Costa County. CCWD’s wholesale water service area includes all or portions of the cities of Antioch, Martinez, Pittsburg, and Diablo Water District (Oakley, Bethel Island, and Knightsen). Water System Description CCWD obtains its water supply exclusively from the Delta and serves treated and untreated (raw)water to approximately 500,000 people in north, central, and east Contra Costa County. CCWD was approved by the voters in 1936 as the legal entity to contract, purchase, and distribute water provided by the United States Bureau of Reclamation (USBR) through the Contra Costa Canal (Canal). For the first 25 years of its existence, CCWD’s main responsibility was the purchase and distribution of untreated water through the Canal. The cities and other water utilities within the CCWD service area were responsible for treating and distributing water used by their customers. However, in the late 1950s, many citizens and public officials became concerned about the quality and cost of the water in the central county area. To address this problem, CCWD purchased the California Water Service Company's Concord-area treatment, pumping, storage, and distribution facilities. In 1968, CCWD replaced the treatment facilities with the construction of the Ralph D. Bollman Water Treatment Plant (Bollman WTP) in Concord. While CCWD initially provided untreated water primarily for irrigation and industry, it is now one of the larger urban water districts in California. Customers include six municipal agencies, major industrial customers, irrigation customers, and retail treated water customers consisting primarily of residential and commercial uses. CCWD’s industrial base includes oil refineries, steel mills, and chemical manufacturing facilities which have historically accounted for approximately one-third of the total water use within CCWD. In providing untreated and treated water, CCWD operates and maintains a complex system of water transmission, treatment, and storage facilities discussed in more detail in the following sections. Contra Costa County–Oak Road Townhouse Condominiums Project Utilities and Service Systems Draft EIR 3.15-2 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-15 Utilities.docx Untreated Water Conveyance Facilities CCWD conveys untreated water to both retail and wholesale municipal customers, as well as industrial and irrigation customers. Wholesale municipal customers include the cities of Antioch, Martinez, and Pittsburg and the Diablo Water District (DWD). Antioch, Martinez, and Pittsburg operate their own water treatment plants and treated water distribution systems. Additionally, CCWD delivers surface water on behalf of the City of Brentwood. CCWD’s primary conveyance facility for its untreated water supply is the Canal, which conveys water diverted from the Delta at the Rock Slough intake for deliveries throughout CCWD's service area. The Canal also has the ability to receive water from the Old River intake, the Middle River intake on Victoria Canal, and Los Vaqueros Reservoir and the Mallard Slough intake. The 48-mile-long Canal originates at Rock Slough and traverses through cities and communities in northeastern and central county areas, terminating at the Martinez Reservoir. Since 2009, CCWD has completed a series of projects to replace the first 4 miles of the Canal, which was previously an earthen channel, to addresses various vulnerabilities including water quality degradation and potential flooding. With the completion of Segment 4 in 2019, approximately 13,500 feet of the Canal has been enclosed in pipe. The final and remaining segment (Segment 5) is anticipated to begin construction by 2025. Within the first 7 miles of the Canal, a series of four pump stations, Pumping Plants 1 through 4, lift water from Rock Slough to a height of 124 feet above sea level from which flows by gravity to the terminus. Starting at Pumping Plant 1, the Canal reaches are concrete lined with capacities ranging from approximately 22 cubic feet per second (cfs) to 350 cfs. The Canal has several in-line siphons, culverts, and check structures, as well as a 1.4-mile tunnel. The first 26 miles of the Canal, termed the “main” Canal, serving Municipal and Industrial (M&I) untreated water customers along its route, including Antioch, Pittsburg, Brentwood, the treated water service area served by Bollman WTP, and the large refineries in the central part of the County. The Shortcut Pipeline, located in central Contra Costa County, originates at the Canal north of the Bollman WTP and terminates at the Martinez Reservoir. This pipeline provides redundancy to a portion of the Canal, known as the Loop Canal, which conveys untreated water from the Canal to Mallard Reservoir (for the Bollman WTP), Martinez Reservoir (for City of Martinez and Martinez Refinery [formerly Shell Oil Company]), as well as several smaller industrial customers. The Ygnacio Re-lift Pump Station diverts water from the Canal into the 5-mile Ygnacio Loop in the City of Walnut Creek. The original Los Vaqueros Pipeline was completed in 1998 and included construction of a 100,000 AF reservoir, a new point of diversion at Old River south of the State Route 4 crossing, transmission facilities, pumping plants, and other associated facilities. The pumping plant at the Old River intake has an installed capacity of 250 cfs, and intake diversions for delivery to the CCWD’s service area began in the summer of 1997. In 2010, CCWD completed construction of a pumping plant on Victoria Canal near Middle River that has an installed capacity of 250 cfs. In 2012, CCWD completed the first phase of the Los Vaqueros Reservoir Expansion Project that expanded the capacity of Los Vaqueros Reservoir from 100,000 acre-feet to 160,000 acre-feet. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Utilities and Service Systems FirstCarbon Solutions 3.15-3 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-15 Utilities.docx The Middle River and Old River pumping plants are permitted to operate at a combined capacity of 320 cfs and pump water to the 4-million-gallon Transfer Reservoir. From the Transfer Reservoir, water can either flow by gravity to the Canal or be pumped at up to 200 cfs by the Transfer Pump Station to the Los Vaqueros Reservoir via the Transfer Pipeline. Water from the Transfer Facility is conveyed by gravity to the Canal via the Los Vaqueros Pipeline and is blended with water supplies from Rock Slough at the Neroly Blending Facility in Antioch. An untreated water intertie connecting the Los Vaqueros Pipeline with East Bay Municipal Utility District (EBMUD’s ) Mokelumne Aqueducts in Brentwood, completed in 2007, enables the wheeling of a portion of CCWD’s Central Valley Project water via the Freeport Regional Water Project and the Mokelumne Aqueducts. The intertie also functions as an emergency connection between EBMUD and CCWD, allowing the districts to share water resources in an emergency. CCWD, other local water agencies, and USBR are currently pursuing Phase 2 of the Los Vaqueros Reservoir Expansion Project, which consists of a reservoir expansion up to 275,000 AFY and related conveyance facilities for regional water supply reliability and ecosystem benefits. CCWD participation in this project does not result in any increased supply for CCWD use. CCWD certified the Final Supplement to the Final Environmental Impact Study/Environmental Impact Report (EIS/EIR) for the Phase 2 Expansion in May 2020, and it has been conditionally awarded $470 million in a Proposition 1 Water Storage Investment Program funding by the California Water Commission. The Final Federal Feasibility Report with the attached EIS/EIR was delivered by USBR to Congress in August 2020 and provides for a federal cost share of up to 25 percent of total project capital costs. A Joint Powers Authority (JPA) is anticipated to be formed in the summer of 2021 to implement the Phase 2 Expansion. Untreated Water Reservoirs CCWD has four untreated water storage reservoirs—Los Vaqueros, Contra Loma, Mallard, and Martinez—with a total storage capacity of approximately 165,000 acre-feet. The Los Vaqueros Reservoir has a capacity of to 160,000 acre-feet and is located 8 miles south of Brentwood. The reservoir stores higher quality Delta water for blending with the Delta supply during dry periods when salinity levels typically increase. Besides improving water quality for CCWD's customers, the reservoir stores water for emergency use by providing a minimum of 70,000 acre-feet of emergency supply in wetter years and 44,000 acre-feet in dry years that could be used during an extreme drought or a catastrophic interruption of CCWD's Delta supplies. Additionally, the reservoir provides environmental benefits including reduced impacts on Delta fisheries. Contra Loma Reservoir is used primarily as a regulating reservoir for peak demands on the Canal, short-term (1–7 days) supplies, and for emergency storage. The reservoir has an operating capacity of about 2,100 acre-feet. Mallard Reservoir provides water to Bollman WTP and is used as a storage facility for emergency use, flow regulation, and blending of the different sources of supply. The reservoir has a usable capacity of about 3,100 acre-feet. Martinez Reservoir, located in Martinez, is at the terminus of the Canal and the Shortcut Pipeline, and has an available capacity of about 276 acre-feet. This water is primarily used by the City of Martinez for its treatment plant and for the Martinez Refining Company (formerly Shell Oil Refinery). It also provides regulating storage to capture flows from Canal operations.

The Bollman WTP serves CCWD’s treated water customers in the central county, and under special agreement, provides treated water to Golden State Water Company (GSWC) for the community of Bay Point. The 75 mgd Bollman WTP treatment process includes coagulation, flocculation, sedimentation, filtration, ozonation, and disinfection. The Randall-Bold Water Treatment Plant (Randall-Bold WTP), located in Oakley, was constructed in 1992 and is jointly owned with the DWD. The treatment process includes a grit basin, influent mixing basin, flocculation, sedimentation, intermediate and post-ozonation, and disinfection. In addition to providing treated water for the DWD, Randall-Bold WTP provides treated water to CCWD’s treated water service area and wholesale municipal customers (GSWC, Antioch, and Brentwood). The Multi- Purpose Pipeline (MPP), constructed in 2003, is a 21-mile pipeline that transports treated water to central Contra Costa County from the Randall-Bold WTP and to wholesale municipal customers. CCWD entered into an agreement with the City of Brentwood in 2004 to treat water for customers in the portion of the City located outside CCWD’s service area boundary. Under this agreement, CCWD constructed, and continues to operate, the Brentwood WTP adjacent to Randall-Bold WTP in 2008. Treatment processes at this plant include coagulation, flocculation, sedimentation, filtration, ozonation, and disinfection. CCWD owns and operates distribution facilities to provide treated water to the treated water service area in central Contra Costa County. Water is pumped from the Bollman WTP and Randall-Bold WTP (via the MPP) to eight pressure zone distribution system through approximately 800 miles of pipeline ranging in diameter from 2 to 66 inches. There are 40 active storage reservoirs with a total storage capacity of approximately 72 million gallons. Thirty pump stations are used to deliver the water and maintain water pressure within the distribution system to serve the approximately 61,000 active service connections. Water Use and Supplies CCWD’s current and project demand and water supply under average, single-dry, and multiple-dry year scenarios in five-year increments are summarized in Table 3.15-1. The projections indicate that CCWD would have adequate water supply under the average, single-dry, and the first three multiple- dry year scenarios; however, demand management measures (i.e., water conservation) would be required for the fourth and fifth multiple-dry year scenarios.

Wastewater flows from Walnut Creek are conveyed north to Central San treatment plant. Treatment Plant Central San treats sewage at its treatment plant in Martinez. The treatment plant has a dry weather effluent discharge limit of 54 mgd, and wet weather flow of 240 mgd. The treatment plant uses ultraviolet disinfection and has secondary treatment capabilities. A portion of the treated effluent receives additional treatment and is used as recycled water; the remaining effluent is released into Suisun Bay via an outfall. The treatment plant is in compliance with all applicable federal and State environmental health and safety standards for treated wastewater. The plant obtains 90 percent of its electricity through a methane cogeneration system with a nearby landfill. Existing Facilities and Effluent Generation The project site has an existing 6-inch diameter service lateral that connects to an existing 12 to 18- inch diameter sewer line in Jones Road. There is a second 4-inch diameter service lateral that connects to an existing 6-inch diameter storm drain line in Oak Road. Using the average daily water consumption of 828 gallons per day, average daily effluent generation was estimated to be 433 gallons per day.1 Storm Drainage The Contra Costa County Flood Control and Water Conservation District owns and maintains drainage facilities within the unincorporated County. Existing Facilities Approximately 60 percent of the project site (155,600 square feet) consists of impervious surfaces. Roughly 78 percent of the site drains to Oak Road and into a 30-inch diameter storm drain line. The remaining 22 percent of the site drains to Jones Road via a 12-inch diameter service lateral that connects to an existing 15-inch diameter storm drain line. Solid Waste Central Contra Costa County Solid Waste Authority (RecycleSmart) is a joint powers agency that oversees solid waste management to the incorporated cities and towns of Danville, Lafayette, Moraga, Orinda, Walnut Creek, and nearby unincorporated areas of Contra Costa County.

These standards set enforceable maximum contaminant levels in drinking water and require all water providers in the United States to treat water to remove contaminants, except for private wells serving fewer than 25 people. In California, the State Department of Health Services conducts most enforcement activities. National Pollutant Discharge Elimination System Pursuant to Section 402 of the CWA and the Porter-Cologne Water Quality Control Act, municipal stormwater discharges in the City of American Canyon are regulated under the San Francisco Bay Region Municipal Regional Stormwater National Pollutant Discharge Elimination System (NPDES) Permit, Municipal Separate Storm Sewer System (MS4) Order No. 2013-001 (General Permit). In 1987, Congress amended the Clean Water Act to mandate controls on discharges from MS4s. Acting under the federal mandate and the California Water Code, California Water Boards require cities, towns, and counties to regulate activities that can result in pollutants entering their storm drains. All municipalities prohibit non-stormwater discharges to storm drains and require residents and businesses to use Best Management Practices (BMPs) to minimize the amount of pollutants in runoff. The Municipal Regional Permit is overseen by the Regional Water Board. On February 5, 2013, California’s State Water Resources Control Board reissued the Phase II Stormwater NPDES Permit for small MS4s. Provision E.12, “Post-Construction Stormwater Management Program,” mandates municipalities to require specified features and facilities—to control pollutant sources, control runoff volumes, rates, and durations, and to treat runoff before discharge from the site—be included in development plans of projects that create or replace 5,000 square feet or more Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Utilities and Service Systems FirstCarbon Solutions 3.15-9 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-15 Utilities.docx impervious surface as conditions of issuing approvals and permits. The new requirements continue a progression of increasingly stringent requirements since 1989. Provision E.12 requires all municipal permittees to implement these requirements by June 30, 2015, to the extent allowed by applicable law. This includes projects requiring discretionary approvals that have not been deemed complete for processing and discretionary permit projects without vesting tentative maps that have not requested and received an extension of previously granted approvals. In July of 2014, the Bay Area Stormwater Management Agencies Association (BASMAA), through the BASMAA Phase II Committee, created the BASMAA Manual to assist applicants for development approvals to prepare submittals that demonstrate their project complies with the NPDES permit requirements. Applicants who seek development approvals for applicable projects should follow the manual when preparing their submittals. The manual is designed to ensure compliance with the requirements and promote integrated Low Impact Development (LID) design. Section E.12.c of the General Permit pertains to LID and how it relates to hydromodification management. This Permit provision requires that stormwater discharges not cause an increase in the erosion potential of the receiving stream over the existing condition. Increases in runoff flow and volume must be managed so that the post-project runoff does not exceed estimated pre-project rates and durations, where such increased flow and/or volume is likely to cause increased potential for erosion of creek beds and banks, silt pollutant generation, or other adverse impacts on beneficial uses due to increased erosive force. State California Porter-Cologne Water Quality Control Act The Porter-Cologne Water Quality Control Act of 1969 (Porter-Cologne Act) is California’s statutory authority for the protection of water quality. Under the Porter-Cologne Act, the State must adopt water quality policies, plans, and objectives that protect the State’s waters for the use and enjoyment of the people. Regional authority for planning, permitting, and enforcement is delegated to the nine Regional Water Quality Control Boards (RWQCBs). The Porter-Cologne Act sets forth the obligations of the California State Water Resources Control Board (State Water Board) and the nine RWQCBs, which engage in a number of water quality functions in their respective regions and regulate all pollutant or nuisance discharges that may affect either surface water or groundwater. The San Francisco Bay RWQCB is responsible for the project site. California Water Code Section 10910 Section 10910 of the California Water Code (as revised by Senate Bill 610) requires: “The city or county, at the time, that it determines whether an environmental impact report, a negative declaration, or a mitigated negative declaration is required for any project subject to the California Environmental Quality Act, pursuant to Section 21080.1 of the Public Resources Code, . . . [to] identify a water system . . . that may supply water for the project,” and to prepare a Water Supply Assessment to address the increased water use over existing conditions.

Identify the water system or systems that would (or may) supply water to the proposed project; 2. Compare project water demands with those projections included in the most-recently adopted Urban Water Management Plan or Plans for those service providers; and 3. Assess whether the public water system’s total projected water availability for the entire system(s) during normal, single-dry, and multiple-dry years over a 20-year period will meet the projected water demand associated with the proposed project, in addition to the public water system’s existing and planned future uses (including agricultural and manufacturing uses). California Water Code Section 10910(4)(d) requires a discussion of existing water supply entitlements, water rights, or water service contracts relevant to the public water system(s). Also, Section 10910 (2)(f) requires that “If a water supply for a proposed project includes groundwater, the following additional information shall be included in the Water Supply Assessment: (1) a review of any information contained in the UWMP relevant to the identified water supply for the proposed project (2) a description of any groundwater basin or basins from which the proposed project will be supplied.” California Urban Water Management Planning Act The Urban Water Management Planning Act (California Water Code §§ 10610-10656) requires that all urban water suppliers prepare UWMPs and update them every 5 years. The act requires that UWMPs include a description of water management tools and options used by that entity that will maximize resources and minimize the need to import water from other regions. Specifically, UWMPs must: • Provide current and projected population, climate, and other demographic factors affecting the supplier’s water management planning. • Identify and quantify, to the extent practicable, the existing and planned sources of water available to the supplier. • Describe the reliability of the water supply and vulnerability to seasonal or climatic shortage. • Describe plans to supplement or replace that source with alternative sources or water demand management measures. • Describe the opportunities for exchanges or transfers of water on a short-term or long-term basis (associated with systems that use surface water). • Quantify past and current water use. • Provide a description of the supplier’s water demand management measures, including schedule of implementation, program to measure effectiveness of measures, and anticipated water demand reductions associated with the measures. • Assess the water supply reliability.

Before additional service connections can be permitted, enough water must be available to the public water system from its water sources and distribution reservoirs to meet the total requirements of all water users adequately, dependably, and safely under maximum-demand conditions. California Senate Bills 610 and 221 Senate Bill (SB) 610 and SB 221 (Water Code § 10910(c)(2)) amended State law, effective January 1, 2002, to improve the link between information on water supply availability and certain land use decisions made by cities and counties. SB 610 and SB 221 seek to promote more collaborative planning between local water suppliers and cities and counties by requiring that detailed information regarding water availability be provided to decision-makers prior to approval of specified large development projects. SB 610 requires that detailed information be included in a Water Supply Assessment (WSA), which is then included in the administrative record that serves as the evidentiary basis for an approval action by a city or county. SB 221 requires that the detailed information be included in a verification of water supply. Under SB 610, WSAs must be furnished to local governments for inclusion in any environmental documentation for certain projects (as defined in Water Code Section 10912(a)) subject to the California Environmental Quality Act (CEQA). A WSA was included in the EBMUD 2015 UWMP that addresses the current and planned future water supply and demand of the water supplier, and makes a determination of the sufficiency of its water supplies existing and planned future uses, including the project site.2 California Water Conservation Act The California Water Conservation Act (SB X7-7) was enacted in November 2009 and requires each urban water supplier to select one of four water conservation targets contained in California Water Code Section 10608.20 with the statewide goal of achieving a 20 percent reduction in urban per capita water use by 2020. Under SBX7-7, urban retail water suppliers are required to develop water use targets and submit a water management plan to the Department of Water Resources (DWR) by July 2011. The plan must include the baseline daily per capita water use, water use target, interim water use target, and compliance daily per capita water use. California Model Water Efficient Landscape Ordinance The Model Water Efficient Landscape Ordinance was adopted by the Office of Administrative Law in September 2009 and requires local agencies to implement water efficiency measures as part of their review of landscaping plans. Local agencies can either adopt the Model Water Efficient Landscape Ordinance or incorporate provisions of the Ordinance into code requirements for landscaping. Governor Brown’s Drought Executive Order of April 1, 2015 (EO B-29-15) directed the DWR to update the State’s Model Water Efficient Landscape Ordinance (Ordinance) through expedited regulation. The California Water Commission approved the revised Ordinance on July 15, 2015. 2 East Bay Municipal Utility District (EBMUD). 2021. Urban Water Management Plan 2020 Public Draft. April.

This applies to residential, commercial, industrial, and institutional projects that require a permit, plan check, or design review. The previous landscape size threshold for new development projects ranged from 2,500 square feet to 5,000 square feet. The size threshold for existing landscapes that are being rehabilitated has not changed, remaining at 2,500 square feet. Only rehabilitated landscapes that are associated with a building or landscape permit, plan check, or design review are subject to the Ordinance. California Integrated Waste Management Act To minimize the amount of solid waste that must be disposed of by transformation and land disposal, the State Legislature passed Assembly Bill (AB) 939, the California Integrated Waste Management Act of 1989, effective January 1990. The legislation required each local jurisdiction in the State to set diversion requirements of 25 percent by 1995 and 50 percent by 2000; established a comprehensive statewide system of permitting, inspections, enforcement, and maintenance for solid waste facilities; and authorized local jurisdictions to impose fees based on the types or amounts of solid waste generated. In 2007, SB 1016, Wiggins, Chapter 343, Statutes of 2008, introduced a new per capita disposal and goal measurement system that moves the emphasis from an estimated diversion measurement number to using an actual disposal measurement number as a per capita disposal rate factor. As such, the new disposal-based indicator (pounds per person per year) uses only two factors: (1) a jurisdiction’s population (or in some cases employment) and (2) its disposal as reported by disposal facilities. Regional San Francisco Bay Regional Water Quality Control Board The San Francisco Bay RWQCB administers the NPDES stormwater permitting program and regulates stormwater in the San Francisco Bay region. Contra Costa County is a permittee under the Phase II NPDES Municipal Stormwater Permit for the Contra Costa Clean Water Program. Stormwater discharges from construction activities on 1 acre or more are regulated by the RWQCB and are subject to the permitting requirements of the NPDES General Permit for Discharges of Stormwater Runoff Associated with Construction Activity (General Construction Permit). The San Francisco Bay RWQCB prepared the San Francisco Bay Basin Water Quality Control Plan (Basin Plan).3 The Basin Plan contains descriptions of the legal, technical, and programmatic bases of water quality regulation in the region and describes beneficial uses of major surface waters and their tributaries.

Contra Costa County Ordinance Code Title 8 Chapter 82-26—Water Conservation Landscaping in New Developments The Water Conservation in Landscaping Act was enacted in 2006, requiring the DWR to update the Model Water Efficient Landscape Ordinance (MWELO). In 2009, the Office of Administrative Law (OAL) approved the updated MWELO, which required a retail water supplier or a county to adopt the provisions of the MWELO by January 1, 2010, or to enact its own provisions equal to or more restrictive than the MWELO provisions. Since the County did not adopt a new landscape Ordinance by January 1, 2010, the proposed project is subject to the MWELO as amended. Title 9 Division 916—Water and Sewers Title 9, Division 916, requires that adequate approved water supply system shall be provided to serve all of a proposed subdivision, that landscaping conform to applicable water conservation requirements, and that sewerage shall be provided to a proposed subdivision by a public sanitation district or utility having adequate plant and facility capacity. Title 10 Division 1010—Drainage Title 10, Division 1010, is adopted to provide for the implementation of drainage, recreation, and riparian vegetation provisions of the General Plan, protect watercourse riparian vegetation, permit control of projects that may change the hydraulic characteristics of watercourses and drainage facilities, control erosion and sedimentation, prevent the placement or discharge of polluting matter into watercourses, and require adequate watercourse drainage facilities.

The CCWD 2015 UWMP evaluates sources of the water supply for the County’s project population and future water demand until 2040, the planning horizon. The CCWD 2015 UWMP is intended to help facilitate implementation of SB 610 and SB 221. 3.15.4 - Impacts and Mitigation Measures According to the CEQA Guidelines Appendix G Environmental Checklist, to determine whether impacts to utilities and service systems are significant environmental effects, the following questions are analyzed and evaluated. Would the project: a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or stormwater drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects? b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry, and multiple-dry years? c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? d) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? e) Comply with federal, State, and local statutes and regulations related to solid waste? Approach to Analysis Wastewater production was calculated and compared with WCWD treatment capacity to determine whether wastewater treatment requirements would be exceeded. In addition, the demand for potable water was calculated to assist in determining whether enough water supply would be available. The County’s wastewater discharge permitting and stormwater requirements were also reviewed. The following evaluation discusses whether the proposed project would result in direct impacts on utilities and service systems such as existing wastewater and stormwater drainage facilities, water supply, or water treatment facilities. The evaluation also discusses whether the proposed project would result in indirect impacts on utilities and services systems, such as construction impacts from new stormwater drainage systems. The analysis involved reviewing published data and material provided by the EBMUD, WCWD, CalRecycle, the County, and the site-specific Stormwater Control Plan and Preliminary Hydrology and Hydraulics Calculations prepared by Ruggeri-Jensen-Azar (included in Appendix G).

Determination of significance of construction-related traffic, air quality, GHG emissions, or noise impacts is based on the respective specific thresholds of significance listed in Section 3.2, Air Quality; Section 3.5, Energy; Section 3.7, Greenhouse Gas Emissions; Section 3.11, Noise; and Section 3.13, Transportation. • Result in insufficient water supply to serve the project’s potable water demand. • Inadequate capacity at the WCWD Treatment Plant to serve the project’s wastewater generation. • Insufficient daily capacity or permitted daily capacity at the Altamont Landfill, Vasco Road Sanitary Landfill, and Keller Canyon Landfill to serve the project’s waste generation. • Unable to comply with AB 939 solid waste diversion goals. Impact Evaluation Water Impact UTIL-1: The proposed project would not require or result in the relocation or construction of new or expanded water, wastewater treatment or stormwater drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects.. Water Water supply would be provided to the proposed project by the CCWD. Because the project site is currently served by the CCWD, its water consumption is factored into the UWMP’s planning projections. Thus, adequate water supplies are available to serve the proposed project and no new or expanded water treatment or conveyance facilities would be required. Furthermore, as discussed under Impact UTIL-2 below, the proposed project would not create the need for new water facilities or result in inefficient water supply. The proposed project would install a new on-site looped water distribution system consisting of 6 to 10-inch diameter pipes that would connect via service lateral to an existing 12-inch diameter water line in Oak Road. CCWD provided a letter to the applicant dated November 10, 2020, confirming it could serve the proposed project and providing standard requirements for new service connections (e.g., separate metering of domestic, fire, and irrigation). Impacts would be less than significant.

Central San provided comments to the applicant dated August 4, 2020, confirming it could serve the proposed project providing standard requirements for new service connections (e.g., payment of connection fees). As described under Impact UTIL-3 below, Central San would contain sufficient capacity to serve all aspects of the project, and a new or expanded wastewater treatment facility would not be required. Therefore, impacts related to wastewater treatment facilities would be less than significant. Stormwater Drainage The proposed project would remove the existing improvements and structures and develop 125 townhomes on the project site. There would be a net increase of 40,136 square feet of impervious surfaces relative to existing conditions (155,600 square feet vs. 195,736 square feet). Under existing conditions, the project site currently has 2.5 acres of impervious surfaces draining to Oak Road and 1.1 acres of impervious surfaces draining to Jones Road. The proposed project would result in 2.2 acres of impervious surfaces draining to Oak Road and 3 acres of impervious surfaces draining to Jones Road. Thus, there would be a net decrease in drainage to Oak Road and a net increase in drainage to Jones Road. As such, the proposed project would need to provide 2,900 cubic feet of runoff storage on-site in the form of bioretention basins. The proposed project would install an on-site storm drainage system. Inlets would capture surface runoff, where it would enter an underground piping system ranging from 12 to 18 inches in diameter that would convey stormwater to bioretention basins or hydromodification vaults. The basins and vaults would be designed to promote percolation into the soil and would release runoff into the municipal drainage system at a rate no greater than the pre-development condition of the project site. In accordance with applicable provisions of Section C.3 of the San Francisco Bay Regional Water Quality Control Board Municipal Regional Permit (Order No. R2-2015-0049, NPDES Permit No. CAS612008) (or more recent permit) as required under Mitigation Measure (MM) HYD-1b, the proposed project would implement LID stormwater management methods into the on-site storm drainage system consisting of rainwater harvesting and use, infiltration, evapotranspiration, or biotreatment. Collectively, these measures would serve to slow, reduce, and meter the volume of runoff leaving the project site and ensure that downstream storm drainage facilities are not inundated with project-related stormwater. Impacts related to stormwater drainage facilities would be less than significant.

Existing overhead utility lines along the proposed project frontage on Oak Road and Jones Road would be relocated underground. As discussed in detail in Section 3.5, Energy, Impacts related to energy use from electric power would be less than significant. Therefore, the proposed project would not result in the relocation or construction of new or expanded electric power facilities, and impacts would be less than significant. Natural Gas No gas service would be provided to the proposed project. As discussed in Section 3.5, Energy, the proposed project would not result in the use of any natural gas. Therefore, there would be no impacts related to natural gas facilities. Telecommunications AT&T would provide phone services, and Comcast would provide phone and high-speed internet services to the project site. The proposed project would not require the construction or expansion of telecommunications facilities because it is located in an urban area that already contains sufficient telecommunications facilities. Therefore, impacts related to need for relocation or construction of new or expanded telecommunications facilities would be less than significant. Level of Significance Less than significant impact. Wastewater Impact UTIL-2: The proposed project would have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple-dry years. Construction Impacts related to sufficient water supplies are limited to operational impacts. No respective construction impacts would occur. Operation Table 3.15-3 summarizes the proposed project’s estimated water consumption. As shown in the table, the proposed project would demand a net increase of 64,843 gallons of water per day, which equates to 72.6 acre-feet per year. This amount of water represents less than 1 percent of both CCWD’s 2025 average water year supply value of 216,600 acre-feet and CCWD’s 2025 single-dry year value of 174,000 shown in Table 3.15-1.

Accordingly, adequate water supplies would be available to serve the project from existing and planned supplies. Therefore, impacts related to sufficient water supply availability would be less than significant. Level of Significance Less than significant impact. Storm Drainage Impact UTIL-3: The proposed project would not result in a determination by the wastewater treatment provider which serves or may serve the project that it does not have adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments. Construction Impacts related to sufficient water supplies are limited to operational impacts. No respective construction impacts would occur. Operation Summarizes the proposed project’s estimated wastewater generation. As shown in the table, the proposed project would generate an estimated 23,344 gallons per day (0.024 mgd). This amount of wastewater represents less than 1 percent of the Central San’s treatment plant daily discharge limit of 54 mgd. Thus, no new or expanded wastewater treatment or conveyance facilities would be required.

Furthermore, as discussed in Impact UTIL-1, Central San provided comments to the applicant dated August 4, 2020, confirming it could serve the proposed project providing standard requirements for new service connections (e.g., payment of connection fees). Therefore, impacts would be less than significant. Level of Significance Less than significant impact. Solid Waste Impact UTIL-4: The proposed project would not generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals. Construction Solid Waste Generation Construction waste generation is summarized in Table 3.15-5. As shown in the table, the proposed project would generate 4,480 cubic yards of construction and demolition waste. The three regional landfills have 136.2 million cubic yards of remaining capacity and, thus, can accommodate the construction solid waste generated by the proposed project.

As a practical matter, Construction and Demolition Debris Recycling practices would divert most, if not all, construction solid waste from landfills. Waste haulers dumping construction debris at transfer stations or landfills are given the option of construction and demolition debris recycling, which typically costs less than dumping in the municipal solid waste stream. Construction and demolition debris recycling involves diverting recoverable materials for reuse or reprocessing, while non-recoverable materials are ground up into Alternative Daily Cover for use at landfills. Impacts would be less than significant.

As shown in the table, the proposed project would generate 321 cubic yards of solid waste annually. The three regional landfills have 136.2 million cubic yards of remaining capacity and, thus, can accommodate the solid waste generated by the proposed project at operation.

Republic Services provides recycling and green waste collection to customers. Aluminum, glass, plastic, paper, carboard, and organic waste are collected and diverted from the waste stream. As such, the values discussed in the table above likely overstate the solid waste generation that would be expected to occur from the proposed project. Impacts would be less than significant. Level of Significance Less than significant impact. Solid Waste Regulations Consistency Impact UTIL-5: The proposed project would comply with federal, State, and local statutes and regulations related to solid waste. Construction During construction, the proposed project would be required to comply with the County’s Municipal Code Title 4 Division 418-2.028 related to solid waste reduction and recycling measures. These measures would ensure compliance with the Integrated Waste Management Act by ensuring project construction waste is transferred to facilities that can adequately recycle solid waste. Thus, with compliance with existing County Municipal Code and the Integrated Waste Management Act, the project would comply with applicable solid waste regulations and statutes during construction, and construction-related impacts would be less than significant. Operation During project operation, the proposed project would be required to comply with applicable State and local regulations related to solid waste such as the California Integrated Waste Management Act and Title 4 Chapter 418 of the Contra Costa County Municipal Code. Adherence to the County Municipal Code would ensure sufficient solid waste collection and transportation is available to the project, and would also ensure that disposal sites contain sufficient capacity through permit review Contra Costa County–Oak Road Townhouse Condominiums Project Utilities and Service Systems Draft EIR 3.15-24 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-15 Utilities.docx and inspections, and recycling programs are implemented in order to divert waste. As such, project operation would not impede the ability of the County to meet waste diversion requirements or cause the County to violate State and local statutes and regulations related to solid waste. Therefore, with compliance with existing State and County law requiring recycling and waste diversion from landfill requirements, operational impacts related to solid waste regulations consistency would be less than significant. Level of Significance Less than significant impact. 3.15.5 - Cumulative Impacts Water The geographic scope of the cumulative potable water analysis is the service area of the CCWD, which provides potable water to residents and businesses within the County. The CCWD considered the existing capacity and future demand for capacity to determine needed updates to water facilities. In the course of preparing the UWMP, the CCWD estimated water demand of future development in the service area and forecast the needed facility upgrades. The forecast included supply facility upgrades needed to accommodate growth in the County. Cumulative projects listed in Table 3-1 (refer to Chapter 3, Environmental Impacts Analysis, Table 3-1, Cumulative Projects) are located within the CCWD service area and would create water supply demand. The CCWD 2015 UWMP determined that CCWD would be able to provide adequate water supplies to the County and cumulative projects area.4 The County would have adequate water supplies to serve the cumulative projects during normal and dry years.5 In addition, cumulative projects listed in Table 3-1, would be required to comply with provisions of the County Code and California Green Building Code related to water conservation. Therefore, the proposed project, in conjunction with identified cumulative projects in Contra Costa County, would result in a less than significant cumulative impact related to water supply and water supply facilities. Wastewater The geographic scope of the cumulative wastewater analysis is the service area of Central San, which provides wastewater collection and treatment services for contracted cities and residents and business in unincorporated County land. Central San considered the existing capacity and future demand for capacity to determine needed updates to wastewater and recycled water facilities. In the course of preparing the Comprehensive Wastewater Master Plan, Central San estimated wastewater generated from future development in the service area and forecast the needed facility upgrades. The forecast included treatment facility upgrades needed to accommodate growth in the County and maintain compliance with applicable regulatory standards for wastewater treatment and discharge. 4 Contra Costa Water District. 2016. 2015 Urban Water Management Plan for the Contra Costa Water District.

The Comprehensive Wastewater Master Plan determined that capacity exists to service the County and cumulative projects area demand with respect to wastewater treatment facilities. Therefore, the proposed project, in conjunction with identified cumulative projects in Contra Costa County would result in a less than significant cumulative impact related to wastewater generation and wastewater treatment facilities. Storm Drainage The geographic scope for cumulative storm drainage is the areas that drain to Walnut Creek, which is the watershed the project site lies within. Cumulative projects listed in Table 3-1 predominantly consist of commercial and non-residential uses located in unincorporated Contra Costa County, the City of Walnut Creek, or the City of Pleasant Hill that generate volumes of stormwater. The proposed project may be required to construct improvements such that the storm drain line is adequate, which may include an expansion of this stormwater facility to ensure that adequate capacity is maintained. Therefore, the proposed project, in conjunction with the construction of other projects and Table 3-1, would not result in a significant cumulative impact related to stormwater generation and stormwater drainage facilities. Solid Waste RecycleSmart, a JPA , oversees regional waste diversion programs and contracts for the solid waste recycling collection services provided within this area of the County. Cumulative projects listed in Table 3-1 consist predominantly of residential uses and would generate solid waste that would increase demand on solid waste facilities to receive, process, and dispose solid waste. The three regional landfills that serve the County have a combined remaining capacity of 136.2 million cubic yards. The anticipated waste volume of cumulative projects development would be 321 cubic yards per year that represents less than 1 percent of the available capacity. Existing solid waste facilities provide sufficient capacity to serve cumulative development anticipated in the County. Therefore, the proposed project, in conjunction with identified cumulative projects, would result in a less than significant cumulative impact related to solid waste generation and landfill capacity. Level of Cumulative Significance Less than significant impact.

This section also evaluates the possible impacts related to wildfire that could result from implementation of the proposed project. Information in this section is based on information provided by the Contra Costa County General Plan (General Plan), Bay Area Air Quality Management District (BAAQMD), California Department of Forestry and Fire Protection (CAL FIRE), and the Contra Costa County Fire Protection District (CCCFPD). No comments were received during the Notice of Preparation (NOP) comment period related to wildfire. 3.16.2 - Environmental Setting Wildfire Hazard Area Designations Contra Costa County Land uses in the Contra Costa County (County) range from rural, agricultural, and open space to urban and developed. Most of the County is identified as moderately susceptible to wildland fire hazards, while isolated areas in the western and central areas of the County have a high susceptibility.1 According to the CAL FIRE Fire Hazard Severity Zone Map, much of the County is in a Moderate, High, and Very High Fire Hazard Zone due to the mountainous terrain and natural vegetation.2 Project Site According to CAL FIRE, the project site is not located in a Moderate, High, or Very High Fire Hazard State Responsibility Area.3 The nearest Fire Hazard Severity Zone is located approximately 2 miles west of the project site (Briones Regional Park) and is designated as a High Fire Hazard Severity Zone.4 Wildfire-conducive Conditions Grasslands and other vegetation in California easily ignite, particularly in dry seasons. Wildfire is a serious hazard in high dry fuel load areas, particularly near areas of natural vegetation and steep slopes, since fires tend to burn more rapidly on steeper terrain. Wildfire is also a serious hazard in areas of high wind, given that fires will travel faster and farther geographically when winds are higher. Furthermore, wildfire is more likely in areas where electric power lines are located above ground where they may encounter vegetation or building materials. 1 Contra Costa County Department of Conservation and Development. 2005.

According to the CAL FIRE, much of the County is in Fire Hazard Severity Zones due its mountainous terrain and natural vegetation. In particular, areas near open spaces, such as Mount Diablo State Park, Briones Regional Park, and Tilden Regional Park, are located in “High” and “Very High” fire hazard severity zones.5 In general, the average wind speed in the County ranges from 2 to 12 miles per hour (mph) and blows northeast.6 Electric power lines mostly occur in urban areas and along roadways. Natural gas pipelines occur frequently across the County, including residential and commercial areas. Natural gas poses a lower risk of causing fire than petroleum products because it is transported at lower pressures and when released, rises and dissipates into the atmosphere.7 There are petroleum and natural gas pipelines that traverse the western portion of the County, generally near the major roadways of Richmond Parkway and Interstate 80 (I-80). Project Site The project site is within the central portion of the County. The site is relatively flat (approximately 90 to 95 feet above mean sea level). The site is developed with structures associated with the former Palmer School for Boys and Girls, a private K-8 school that operated from 1939 until its closure due to COVID-19 in June 2020. These structures include 14 vacant buildings as well as associated structures, including classrooms, an auditorium, a front office, a paved courtyard, a grass field, tennis courts, basketball courts playgrounds, a swimming pool, parking lots, and planters. Several planter boxes, storm drain lines, power boxes, and a partially uncovered pipe which appears to be related to storm drainage are located along the southern boundary of the property. The project site does not contain any creeks or bodies of water. The closest creek to the project site is Walnut Creek, located approximately 1,750 feet to the south. The Contra Costa Canal is approximately 450-600 feet to the south. The project site is located within an urbanized area and is surrounded by features that provide fuel breaks in the event of a fire, such as I-680, the Contra Costa Canal, Oak Road, and Jones Road. The BAAQMD monitors the Bay Area’s air quality at a number of stations, and the closest station to the project site is located in the City of Concord, approximately 4 miles to the northeast. The average wind speed at this station varied from month to month and ranged from 7 to 16 mph in 2020.8 Fire Protection and Emergency Medical Services Northern California CAL FIRE is responsible for fire protection and stewardship of over 31 million acres of California’s privately owned wildlands. CAL FIRE also provides varying levels of emergency services in 36 of the 5 California Department of Forestry and Fire Protection (CAL FIRE). 2007.

Because of the Department’s size and major incident management experience, it is often asked to assist or take the lead in disasters.9 In October 2017, a series of wildfires occurred in Northern California resulting in extensive property damage. In November 2018, the Camp Fire wildfire occurred in Northern California, resulting in the deadliest wildfire to occur in State history.10 In September and October 2020, the Glass Fire burned more than 67,484 acres and destroyed 1,555 structures, Napa and Sonoma Counties.11 In August 2020, the North Complex Fire and the LNU Lightning Complex burned approximately 318,935 and 363,220 acres respectively in several counties in Northern California, and destroyed 2,352 and 1,491 structures respectively.12 Contra Costa County The CCCFPD provides fire protection and emergency medical services in and around the 19 cities and unincorporated communities of the County. The CCCFPD serves the County with 26 fire stations, and with few exceptions, County emergency ambulance transport services are provided by the CCCFPD through its unique sub-contractor Alliance model.13 The CCCFPD consists of 19 engine companies, five truck companies, and maintains 24 fully staffed stations and two more stations staffed with paid on-call personnel. The 24 on-duty companies are trained and regularly cross-staff numerous specialty response units including 18 wildland fire apparatus, three rescue units, a trench rescue unit, a fire rescue boat, and a mobile breathing air support unit.14 According to the General Plan, wildfire hazards are a considerable problem in undeveloped areas and in areas of extensive unirrigated vegetation. Areas of Central Contra Costa County that contain steep slopes and are covered with natural vegetation (e.g., Mount Diablo State Park, Briones Regional Park, and Tilden Regional Park) as well as areas in East County outside the urban limit line that are used as dry farming of grains for feed are extremely flammable during the late summer and fall.15 The County Office of the Sheriff Emergency Services Division is responsible for planning, outreach, and training or disaster management and emergency preparedness.16 Per Policy 7-62 of the General Plan, the County strives to reach a maximum running time of 3 minutes and/or 1.5 miles from the nearest fire station.17 The main routes into and out of the County that would most likely serve as evacuation routes are I-80, Interstate 680 (I-680), and Interstate 580 (I-580), as well as State Route (SR) 4 and SR-24. 9 California Department of Forestry and Fire Protection (CAL FIRE). 2021.

The main arterial roads into and out of the project vicinity are Jones Road and Oak Road, which would serve as the main emergency response and evacuation routes into and out of the project vicinity. Post-fire Slope Instability and Drainage Pattern Changes Slope instability from wildfire scarring of the landscape can result in more intensive flooding and landslides. These post-fire slope soils and altered drainage patterns can more easily creep away downslope sides of foundations and can also reduce lateral support. Contra Costa County The major post-wildfire hazards in the County are unstable hill slopes and altered drainage patterns. Slopes may suffer landslides, slumping, soil slips, and rockslides. The General Plan has historically recognized that major slope areas in excess of 26 percent are “not readily developable” or “undevelopable,” recognizing the cost and engineering difficulties of grading steep slopes as well as their inherent unsuitability for development.18 Figure 10-6 of the General Plan shows Landslide Hazards in the County. In 2018, 2019, and 2020, there were nine, nine, and six CAL FIRE reported incidents in the County, respectively.19, 20, 21 As of May 24, 2021, there were no current year CAL FIRE reported incidents in the County.22 Project Site According to Figure 10-6 of the General Plan, the project site is not located on a site susceptible to landslides or an area where landslides previously occurred. Current on-site drainage and storm runoff generally sheet flows across the site or captured by on-site small drainage inlets connected by underground storm drain pipes and discharged into the existing storm drain facilities in Jones Road or Oak Road. Furthermore, wildfire has not previously occurred on the project site. 3.16.3 - Regulatory Framework Federal United States Department of Interior Review and Update of the 1995 Federal Wildland Fire Management Policy 1.

Fire Management and Ecosystem Sustainability—The full range of fire management activities will be used to help achieve ecosystem sustainability, including its interrelated ecological, economic, and social components. 3. Response to Wildland Fire—Fire, as a critical natural process, will be integrated into land and resource management plans and activities on a landscape scale, and across agency boundaries. Response to wildland fire is based on ecological, social, and legal consequences of the fire. The circumstances under which a fire occurs, and the likely consequences on firefighter and public safety and welfare, natural and cultural resources, and values to be protected dictate the appropriate management response to the fire. 4. Use of Wildland Fire—Wildland fire will be used to protect, maintain, and enhance resources and, as nearly as possible, be allowed to function in its natural ecological role. Use of fire will be based on approved Fire Management Plans and will follow specific prescriptions contained in operational plans. 5. Rehabilitation and Restoration—Rehabilitation and restoration efforts will be undertaken to protect and sustain ecosystems, public health, and safety, and to help communities protect infrastructure. 6. Protection Priorities—The protection of human life is the single, overriding priority. Setting priorities among protecting human communities and community infrastructure, other property and improvements, and natural and cultural resources will be based on the values to be protected, human health and safety, and the costs of protection. Once people have been committed to an incident, these human resources become the highest value to be protected. 7. Wildland Urban Interface—The operational roles of federal agencies as partners in the Wildland Urban Interface are wildland firefighting, hazardous fuels reduction, cooperative prevention and education, and technical assistance. Structural fire suppression is the responsibility of tribal, State, or local governments. Federal agencies may assist with exterior structural protection activities under formal Fire Protection Agreements that specify the mutual responsibilities of the partners, including funding. (Some federal agencies have full structural protection authority for their facilities on lands they administer and may also enter into formal agreements to assist State and local governments with full structural protection.) 8. Planning—Every area with burnable vegetation must have an approved Fire Management Plan. Fire Management Plans are strategic plans that define a program to manage wildland and prescribed fires based on the area’s approved land management plan. Fire Management Plans must provide for firefighter and public safety; include fire management strategies, tactics, and alternatives; address values to be protected and public health issues; and be consistent with resource management objectives, activities of the area, and environmental laws and regulations.

Science—Fire Management Plans and programs will be based on a foundation of sound science. Research will support ongoing efforts to increase our scientific knowledge of biological, physical, and sociological factors. Information needed to support fire management will be developed through an integrated interagency fire science program. Scientific results must be made available to managers in a timely manner and must be used in the development of land management plans, Fire Management Plans, and implementation plans. 10. Preparedness—Agencies will ensure their capability to provide safe, cost-effective fire management programs in support of land and resource management plans through appropriate planning, staffing, training, equipment, and management oversight. 11. Suppression—Fires are suppressed at minimum cost, considering firefighter and public safety, benefits, and values to be protected, consistent with resource objectives. 12. Prevention—Agencies will work together and with their partners and other affected groups and individuals to prevent unauthorized ignition of wildland fires. 13. Standardization—Agencies will use compatible planning processes, funding mechanisms, training and qualification requirements, operational procedures, values-to-be-protected methodologies, and public education programs for all fire management activities. 14. Interagency Cooperation and Coordination—Fire management planning, preparedness, prevention, suppression, fire use, restoration and rehabilitation, monitoring, research, and education will be conducted on an interagency basis with the involvement of cooperators and partners. 15. Communication and Education—Agencies will enhance knowledge and understanding of wildland fire management policies and practices through internal and external communication and education programs. These programs will be continuously improved through the timely and effective exchange of information among all affected agencies and organizations. 16. Agency Administrator and Employee Roles—Agency administrators will ensure that their employees are trained, certified, and made available to participate in the wildland fire program locally, regionally, and nationally as the situation demands. Employees with operational, administrative, or other skills will support the wildland fire program, as necessary. Agency administrators are responsible and will be held accountable for making employees available. 17. Evaluation—Agencies will develop and implement a systematic method of evaluation to determine effectiveness of projects through implementation of the 2001 Federal Fire Policy. The evaluation will assure accountability, facilitate resolution of areas of conflict, and identify resource shortages and agency priorities. State California Emergency Response Plan California has developed an emergency response plan to coordinate emergency services provided by federal, State, and local governments and private agencies. Responding to wildfire incidents is one Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Wildfire FirstCarbon Solutions 3.16-7 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-16 Wildfire.docx part of this plan. The plan is administered by the California Governor’s Office of Emergency Services, which coordinates the responses of other agencies. The County Office of the Sheriff’s Emergency Services Division coordinates response to emergencies in unincorporated areas of the County. Emergency response team members respond and work with local fire and police agencies, emergency medical providers, the California Highway Patrol, CAL FIRE, the California Department of Fish and Wildlife (CDFW), and California Department of Transportation (Caltrans). California Department of Forestry and Fire Protection Threat Potential Mapping CAL FIRE has mapped fire threat potential throughout California. CAL FIRE maps fire threat based on the availability of fuel and the likelihood of an area burning (based on topography, fire history, and climate). The threat levels include no fire threat, moderate, high, and very high fire threat. Further, the maps designate the County as the Local Responsibility Area (LRA) for the project site. Additionally, CAL FIRE produced a 2010 Strategic Fire Plan for California, which contains goals, objectives, and policies to prepare for and mitigate the effects of fire on California’s natural and built environments. CAL FIRE’s Office of the State Fire Marshal provides oversight of enforcement of the California Fire Code as well as overseeing hazardous liquid pipeline safety. California Building Standards Code The State of California provided a minimum standard for building design through the 2019 California Building Standards Code (CBC), which is located in Part 2 of Title 24 of the California Code of Regulations. The 2019 CBC is based on the 2018 International Building Code, but has been modified for California conditions. It is generally adopted on a jurisdiction by-jurisdiction basis, subject to further modification based on local conditions. Commercial and residential buildings are plan- checked by local City and County building officials for compliance with the CBC. Typical fire safety requirements of the CBC include the installation of sprinklers in all new high-rise buildings and residential buildings; the establishment of fire resistance standards for fire doors, building material; and specific types of construction. California Public Resources Code The California Public Resources Code includes fire safety regulations that restrict the use of equipment that may produce a spark, flame, or fire; require the use of spark arrestors on construction equipment that use an internal combustion engine; 23 specify requirements for the safe use of gasoline-powered tools in fire hazard areas; and specify fire suppression equipment that must be provided on-site for various types of work in fire-prone areas. These regulations include the following: • Earthmoving and portable equipment with internal combustion engines shall be equipped with a spark arrestor to reduce the potential for igniting a wildland fire (Public Resources Code [PRC] § 4442); 23 A spark arrestor is a device that prohibits exhaust gases from an internal combustion engine from passing through the impeller blades where they could cause a spark. A carbon trap is commonly used to retain carbon particles from the exhaust.

Regional Association of Bay Area Governments Hazard Mitigation Plan The Association of Bay Area Governments (ABAG) multi-jurisdictional Local Hazard Mitigation Plan for the San Francisco Bay Area was updated in 2010 in partnership with the Bay Conservation and Development Commission. Adapting to Rising Tides Program to support local governments in the regional plan for existing and future hazards of climate change. This detailed 5-year plan identifies potential natural and human-made hazards, assesses their potential risks, and includes mitigation methods to reduce risks. The potential hazards identified in the plan include earthquakes and liquefaction, wildfires, floods, drought, solar storms, dam or levee failure, disease outbreak, freezes, wind, heat, thunder and lightning storms, siltation, tornadoes, hazardous materials, slope failure and mudflows, and other hazards. Similarly, mitigation measures include hazard event planning, emergency preparedness coordination, education, facility upgrades, and monitoring actions. Local Contra Costa County Hazard Mitigation Plan The County and a partnership of local governments within the County have developed a Hazard Mitigation Plan (HMP) to reduce future losses resulting from disasters. Hazard mitigation is the use of long- and short-term strategies to reduce the loss of life, personal injury, and property damage that can result from a disaster. It involves planning efforts, policy changes, programs, capital projects, and other activities that can mitigate the impacts of hazards. The HMP contains the following goals aimed at reducing the vulnerability from natural hazards within the County in a cost-effective manner: Goal 1 Save, or protect lives and reduce injury. Goal 2 Increase resilience of infrastructure and critical facilities. Goal 3 Avoid, minimize, or reduce damage to property. Goal 4 Encourage the development and implementation of long-term, cost-effective, and environmentally sound mitigation projects.

Contra Costa Emergency Operations Plan The County Operational Area Emergency Operations Plan (EOP) addresses response to emergency incidents affecting the County. The Contra Costa Operational Area consists of the cities/towns, special districts, reclamation districts, municipal improvement districts and the unincorporated areas within the County. The EOP is based on the functions and principles of the California Standardized Emergency Management System, the National Incident Management System, and the Incident Command System. It identifies how the County emergency operational system fits into the overall California and national risk-based, all-hazard emergency response and recovery operations plans. Contra Costa County General Plan Public Facilities/Services Element The General Plan Public Facilities/Services Element establishes the following goals, policies, and implementation measures related to wildfire hazards relevant to this analysis: Goal 7-AA To incorporate requirements for fire-safe construction into the land use planning and approval process. Goal 7-AD To provide special fire protection for high-risk land uses and structures. Policies Policy 7-64 New development shall pay its fair share of costs for new fire protection facilities and services. Policy 7-66 Sprinkler systems may be required in new residential structures, where necessary to protect health, safety and welfare. Policy 7-80 Wildland fire prevention activities and programs such as controlled burning, fuel removal, establishment of fire roads, fuel breaks and water supply, shall be encouraged to reduce wildland fire hazards. Policy 7-81 All structures located in Hazardous Fire Areas, as defined in the Uniform Fire Code, shall be constructed with fire-resistant exterior materials, such as fire-safe roofing, and their surroundings are to be irrigated and landscaped with fire-resistant plants, consistent with drought resistance and water conservation policies. Policy 10-89 Every high-rise building shall be designed and constructed to provide for the evacuation of occupants and/or for the creation of a safe environment in case of a substantial disaster, such as a severe earthquake or fire. Contra Costa County–Oak Road Townhouse Condominiums Project Wildfire Draft EIR 3.16-10 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-16 Wildfire.docx Implementation Measures Implementation Measure 7-at The Conservation and Development Department shall include fire agency code requirements requested by the districts as advisory notes to the applicant within proposed conditions of project approval when the Planning Agency is considering subdivisions, development plans, use permits and other entitlement requests. Implementation Measure 7-au Fire protection agencies shall be afforded the opportunity to review projects and submit conditions of approval for consideration to determine whether: - There is an adequate water supply for fire fighting - Road widths, road grades and turnaround radii are adequate for emergency equipment; and - Structures are built to the standards of the Uniform Building Code, the Uniform Fire Code, other State regulations, and local ordinances regarding the use of fire- retardant materials and detection, warning and extinguishment devices. 3.16.4 - Impacts and Mitigation Measures According to the California Environmental Quality Act (CEQA) Guidelines Appendix G Environmental Checklist, to determine whether wildfire impacts would be considered significant from implementation of the proposed project, the following questions are analyzed and evaluated. If located in or near State responsibility areas or lands classified as very high fire hazard severity zones, would the project: a) Substantially impair an adopted emergency response plan or emergency evacuation plan? b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire? c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes? Approach to Analysis The project site is not located in a “Fire Hazard Severity Zone” in a State Responsibility Area (SRA) or a “Very High Fire Hazard Severity Zone” in a local, State, or federal responsibility area. The closest designated “Very High Fire Hazard Severity Zone” is located approximately 2 miles to the southeast of the project site (Briones Regional Park). The BAAQMD monitors the Bay Area’s air quality at a number of stations, and the closest station to the project site is located in the City of Concord, Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Wildfire FirstCarbon Solutions 3.16-11 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-16 Wildfire.docx approximately 4 miles to the northeast. The average wind speed at this station varied from month to month and ranged from 7 to 16 mph in 2020.24 As the project site is located 2 miles from an SRA or lands classified as “Very High Fire Hazard Severity Zone,” this evaluation focuses on whether the project would result in changes to the physical environment that would cause or exacerbate adverse effects related to wildfires or whether the project would be placed in a location susceptible to wildfire or post-wildfire conditions. The evaluation also includes a determination of whether changes to the physical environment caused by the project would impair or interfere with emergency response plans, expose people to pollutant concentrations from a wildfire or uncontrolled spread of a wildfire, expose people/structures to downslope flooding or landslides, or include installation or maintenance of infrastructure that may exacerbate fire risk. The following analysis is based, in part, on information provided by the General Plan and CAL FIRE website. Specific Thresholds of Significance For purposes of this analysis, the following thresholds are used to evaluate the significance of wildfire impacts resulting from implementation of the project. • Impaired implementation of or interference with an adopted emergency response plan or emergency evacuation plan via blockage of an evacuation route or provision of only one access point for emergency vehicles. • Location in or near area of steep slopes, high wind areas, or historical wildfire burn areas leading to greater wildfire risk and, thereby, exposing project occupants to smoke and other wildfire-related air pollutants. • Installation or maintenance of roads, fuel breaks, emergency water sources, electrical power lines, or natural gas lines that may exacerbate fire risk. • Location in or near area of wildfire-scarred slopes or altered drainage areas and, thereby, exposing project occupants to flooding and landslide hazards. Impact Evaluation Emergency Response/Evacuation Plan Consistency Impact WILD-1: The proposed project would not substantially impair an adopted emergency response plan or emergency evacuation plan. Construction During construction, it is expected that construction equipment and vehicles would be accessing and leaving the project site, which could potentially impede evacuation or emergency vehicle access. However, as discussed under Impact TRANS-3 and Impact HAZ-6, the proposed project would result in less than significant impacts related to emergency vehicle access. In addition, the proposed 24 Bay Area Air Quality Management District (BAAQMD). 2019. Meteorology Data.

Contra Costa County–Oak Road Townhouse Condominiums Project Wildfire Draft EIR 3.16-12 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-16 Wildfire.docx project would comply with the County EOP, ensuring efficient response to emergency incidents associated with emergencies affecting the County. Furthermore, blockage of an evacuation route would not occur during project construction because the proposed project would not result in road closures to either Oak Road or Jones Road, the most likely evacuation routes from the project site. Therefore, construction impacts related to emergency response/evacuation plan consistency would be less than significant. Operation As indicated in Section 3.13, Public Services, Impact PUB-1 and PUB-2, and Section 3.8, Hazards and Hazards Materials, Impact HAZ-6, the proposed project would be adequately served by police and fire services, including respective evacuation or emergency vehicle access. The proposed project would not create a permanent increase in population unaccounted for in the General Plan that could lead to overwhelming calls for emergency services. In addition, the proposed project would be designed in accordance with the County’s standards to accommodate emergency vehicle access by providing two points of access to the project site and internal roadways that would be available to emergency vehicles. Furthermore, blockage of an evacuation route would not occur during project operation because the proposed project would not result in road closures to Oak Road or Jones Road, the most likely evacuation routes from the project site. With adherence to General Plan Policy 7-64, and Implementation Measures 7-at and 7-au, which recommend and require development fees, fire agency project review, and creation of a safe environment in case of substantial disaster, the proposed project would not conflict with the County EOP or General Plan. Therefore, operational impacts related to emergency response/evacuation plan consistency would be less than significant. Level of Significance Less than significant impact. Expose Project Occupants to Pollutant Concentrations from Wildfire Impact WILD-2: The proposed project would not due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire. Construction Impacts related to exposure of project occupants to pollutants concentrations from wildfire are limited to operational impacts. No respective construction impacts would occur. Operation As indicated by the General Plan, fire hazards present a considerable problem throughout the County, primarily within undeveloped areas with natural vegetation and steep slopes. The project site is located within the central portion of the County and is relatively flat (approximately 90 to 95 feet above mean sea level). The project site is mostly surrounded by urbanized uses on relatively flat areas lacking in woodlands or vegetation that could provide fuel load for wildfire, or steep slopes that could cause fire to spread more rapidly. The project site is surrounded by other features that provide fuel breaks in the event of a fire, such as I-680, the Contra Costa Canal, Oak Road, and Jones Road. The closest open space area (Briones Regional Park) is located approximately 3 miles west of the project site. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Wildfire FirstCarbon Solutions 3.16-13 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-16 Wildfire.docx According to CAL FIRE, the project site is not located in an SRA or an LRA Fire Hazard Severity Zone.25 The nearest Fire Hazard Severity Zone is located approximately 2 miles west of the project site (Briones Regional Park) and is designated as a High Fire Hazard Severity Zone.26 The BAAQMD monitors the Bay Area’s air quality at a number of stations, and the closest station to the project site is located in the City of Concord, approximately 4 miles to the northeast. The average wind speed at this station varied from month to month and ranged from 7 to 16 mph in 2020.27 Given that the project site is not located on or near steep terrain surrounded by natural vegetation, is mostly surrounded by urban uses, and does not consistently experience high winds, the project site would not be prone to wildfires. Compliance with applicable State and local plans and regulations would decrease the risk of impacts related to wildland fire hazards. Specifically, General Plan policies incorporate requirements for fire- safe construction into the land use planning and approval process and ensure special fire protection for high-risk land uses and structures. The County also implements an EOP, which addresses response to emergency incidents affecting the County. Furthermore, as indicated in Section 3.13, Public Services and Recreation, the proposed project would be adequately served in terms of fire protection services by the CCCFPD. Finally, the proposed project would be required to comply with the California Fire Code regarding emergency access and types of building materials. Therefore, impacts related to exposure of project occupants to pollutant concentrations from a wildfire or uncontrolled spread of wildfire would be less than significant. Level of Significance Less than significant impact. Infrastructure That Exacerbates Fire Risk Impact WILD-3: The proposed project would not require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment. Construction Impacts related to installation or maintenance of infrastructure (such as roads, fuel breaks, emergency water sources, electrical power lines, or natural gas lines) that may exacerbate fire risk are limited to operational impacts. No respective construction impacts related to infrastructure that exacerbates fire risk would occur. Operation The proposed project would include adequate emergency access via existing roads at two access points. The project site is in an urban area surrounded by existing roadways.

The proposed project would not require emergency water sources, because potable water is currently provided by the Contra Costa Water District, which has adequate water supplies available to serve the project and future development during normal, dry, and multiple dry years. New electrical power and natural gas lines on and connecting to the project site would be installed underground, minimizing potential ignition and related fire risk above ground, at the project site according to the CBC, Uniform Fire Code, and Contra Costa County General Plan Implementation Measure 7-au. Finally, off-site improvements, including frontage sidewalks, driveway curbs, and gutter improvements, would not exacerbate fire risk. Therefore, impacts related to infrastructure that exacerbates fire risk would be less than significant. Level of Significance Less than significant impact. Flooding and Landslide Hazards Due to Post-fire Slope Instability/Drainage Changes Impact WILD-4: The proposed project would not expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes. Construction Impacts related to post-fire slope instability are limited to operational impacts. No respective construction impacts related to flooding and landslide hazards due to post-fire slope instability or drainage changes would occur. Operation The project site is not located on or near steep slopes susceptible to landslides or downstream flooding. The project site has also not been affected by previous wildfires that could have resulted in drainage changes or loss of vegetation. Therefore, impacts related to flooding and landslide hazards due to post-fire slope instability or drainage changes would be less than significant. Level of Significance Less than significant impact. 3.16.5 - Cumulative Impacts The geographic scope of the cumulative analysis related to wildfire is the project vicinity or roughly the western portion of the County. The analysis also considers the foreseeable development projects listed in Chapter 3, Environmental Impact Analysis, Table 3-1, Cumulative Projects, in unincorporated Contra Costa County and the surrounding cities, in addition to the proposed project. Wildfire Hazards and Emergency/Evacuation Response A combination of federal, State, and local regulations limit or minimize the potential for exposure to wildfires by reducing the amount of development in wildland urban interface areas, ensuring new development is developed according to the CBC and Uniform Fire Code, and incorporating requirements for fire-safe construction into the land use planning. Development listed in Table 3-1 Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Wildfire FirstCarbon Solutions 3.16-15 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec03-16 Wildfire.docx consists predominantly of residential and commercial development. Only one of the projects anticipated in Table 3-1 would be located in designated and High or Very High Fire Hazard Zones. Project 2 is located on the edge of a High Fire Hazard Zone. However, this project, as all the other projects listed in Table 3-1, would be in areas that are already developed, and do not contain significant levels of dry fuel susceptible to ignition, or significantly high average wind speeds. The cumulative projects listed in Table 3-1, would result in predominantly in-fill development and would not significantly increase emergency services beyond the existing service area. Furthermore, all cumulative project construction would adhere to the County Building Codes that are designed to minimize the potential for uncontrolled fires. Adherence to County Building Codes would ensure that California Fire Code standards such as automatic sprinkler systems and management of fuel loads in response to annual inspection by the Fire Department are included in development. Once cumulative development is proposed, the County assesses the needs for fire protection services and informs efforts to improve or expand needed facilities. All development would, however, comply with emergency access requirements, such as two emergency vehicle access points, as a condition of construction. Furthermore, the cumulative projects would not result in permanent road closures, nor impede an established emergency or evacuation access route, such as I-680, or interfere with emergency response requirements, such as fire protection response time standards established by the General Plan. As such, there would be a less than significant cumulative impact associated with wildfire hazards and emergency/evacuation response. Level of Cumulative Significance Less than significant impact. THIS PAGE INTENTIONALLY LEFT BLANK Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Alternatives to the Proposed Project FirstCarbon Solutions 4-1 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec04-00 Alternatives.docx CHAPTER 4: ALTERNATIVES TO THE PROPOSED PROJECT 4.1 - Introduction The following section contains a comparative impact assessment of potentially feasible alternatives to the proposed project. The primary purpose of an alternatives analysis under the California Environmental Quality Act (CEQA) is to provide the decision makers, other interested parties, and the general public with a reasonable number of potentially feasible project alternatives that could attain most of the basic project objectives, while avoiding or reducing any of the proposed project’s significant adverse environmental effects. However, as demonstrated by the administrative record for this project, all impacts of the proposed project are less than significant or can be mitigated to below a level of significance; therefore, the proposed project does not have any significant unavoidable impacts. Findings rejecting alternatives are required only if one or more significant environmental effects will not be avoided or substantially lessened by mitigation measures. When approving a project, Contra Costa County (County), as the lead agency, need not make findings rejecting the alternatives described in the Draft Environmental Impact Report (Draft EIR) where all of the proposed project’s significant impacts will be avoided or substantially lessened by mitigation measures. (See Laurel Hills Homeowners Assn v. City Council (1978) 83 Cal. App. 3rd 515 [if mitigation measures substantially lessen a project’s significant environmental effects, the lead agency may approve the project without making findings on the feasibility of the EIR’s project alternatives]; see also Stevens v. City of Glendale (1981) 125 Cal. App. 3rd 986, 996; No Slo Transit, Inc. v. City of Long Beach (1987) 197 Cal. App. 3rd 241].) Thus, if the County finds that all of the proposed project’s significant adverse effects will be avoided or substantially lessened by mitigation measures, it need not make findings that environmentally superior alternatives are infeasible. (See Mira Mar Mobile Community v. City of Oceanside (2004) 119 Cal. App. 4th 477; Protect Our Water v. County of Merced (2003) 110 Cal. App. 4th 362, 373; Kings County Farm Bureau v City of Hanford (1990) 221 Cal. App. 3rd 692.). An EIR must describe a reasonable range of alternatives to the proposed project, or to its location, that would feasibly attain most of the project's basic objectives while reducing or avoiding any of its significant effects. The discussion of alternatives is subject to a rule of reason and the scope of alternatives to be analyzed must be evaluated on the facts of each case. Accordingly, analysis of the following two alternatives to the proposed project is provided for discussion purposes and to allow the decision makers to consider the proposed project in light of hypothetical alternative development scenarios, thereby promoting CEQA’s purpose as an information disclosure statute. This analysis is guided by the following considerations set forth under CEQA Guidelines Section 15126.6: • An EIR need not consider every conceivable alternative to a project; • An EIR should identify alternatives that were considered by the lead agency, but rejected as infeasible during the scoping process; • Reasons for rejecting an alternative include: Contra Costa County–Oak Road Townhouse Condominiums Project Alternatives to the Proposed Project Draft EIR 4-2 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec04-00 Alternatives.docx - Failure to meet most of the basic project objectives; - Infeasibility; or - Inability to avoid significant environmental effects. 4.1.1 - Significant Unavoidable Impacts The proposed project was analyzed for potentially significant impacts related to each of the environmental topic areas discussed in Sections 3.1 through 3.16. The results of the analysis demonstrate that the proposed project would not result in any significant and unavoidable impacts. 4.1.2 - Alternatives to the Proposed Project For discussion purposes, this Draft EIR presents a reasonable range of potentially feasible alternatives to the proposed project for analysis and evaluation of their comparative merits, pursuant to CEQA Guidelines Section 15126.6, discussed above. Where a project does not include any significant and unavoidable impacts and the potential impacts associated with a project can all be reduced to below a level of significance with the incorporation of mitigation, the analysis properly considers alternatives that would also reduce or eliminate those less than significant with mitigation impacts. CEQA Guidelines Section 15126.6(a) states that an EIR need not evaluate every conceivable alternative to a project. For informational purposes the following analysis is provided for each alternative to allow a meaningful comparison with the proposed project. The proposed project would result in less than significant impacts with mitigation incorporated for the following environmental topic areas: • Aesthetics, Light, and Glare • Air Quality • Biological Resources • Cultural Resources and Tribal Cultural Resources • Geology and Soils • Hazards and Hazardous Materials • Hydrology and Water Quality • Noise • Public Services and Recreation The two alternatives to the proposed project analyzed in this section are as follows: Alternative 1–No Project, No Build Alternative: Under the No Project, No Build Alternative, the proposed project would not be constructed. The closed, vacant private school and its associated structures would remain on-site, and no development of any kind would occur. For the purposes of this alternatives analysis, it is assumed that the existing buildings would remain vacant and no educational, or other alternative, land use activities would occur. Alternative 2–Reopening the Palmer School Alternative: Under the reopening of the Palmer School Alternative, the currently closed school would reopen and resume operations as a private nonsectarian, co-educational school, serving Junior Kindergarten to Eighth Grade students. All Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Alternatives to the Proposed Project FirstCarbon Solutions 4-3 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec04-00 Alternatives.docx buildings and structures would remain in place, no trees would be removed, and no new development would take place on the project site. The school would resume operations at the same level as at the time of school closure in June 2020. Reopening the Palmer School would require compliance with and obtaining approvals/permits from the State Department of Education and/ or appropriate local agencies. This process would include obtaining a land use permit from Contra Costa County. The school would continue its mission to offer an alternative to the larger class size and teacher ratio of public schools. The school would resume operating with a low student-to-faculty ratio and structured academic program that includes on-campus sports and community-based activities. Under this alternative, the school would return to its pre-closure enrollment of approximately 370- 400 students, employing approximately 45-52 staff members. School hours would follow pre-closure hours and would be open Monday through Friday, from 7:00 a.m. until 6:00 p.m., with grade-level specific hours as follows: Junior Kindergarten 8:30 a.m. to 11:30 a.m., Kindergarten 8:30 a.m. to 1:00 p.m., First Grade 8:30 a.m. to 2:00 p.m., Second and Third Grades 8:30 a.m. to 2:30 p.m., and Fourth through Eighth Grades 8:30 a.m. to 3:30 p.m. Consistent with the pre-closure schedule, students would be allowed on campus as early as 8:00 a.m. and could remain until 4:00 p.m. daily. An extended day program would be available before and after these hours (7:00-8:00 a.m. and 4:00- 6:00 p.m.). The school would also host nighttime meetings for parents, scouting meetings, and other activities. Consistent with pre-closure activity, during the summer months, the school would offer a 10-week recreational program for children aged four to eleven years old. Activities would include arts and crafts, organized sports and games, nature study, cooking, science, swimming, camp songs and more. Summer camp would enroll approximately 100-160 students and employ approximately 25 staff members. The camp would operate Monday through Friday (with the exception of Independence Day observance) from 9:00 a.m. to 3:30 p.m. Extended day care would be offered before and after the camp hours similar to school days. 4.2 - Project Objectives As stated in Section 2, Project Description, the objectives of the proposed project are to: • Develop an appropriate mix of multi-family units (including affordable units) that meets the existing General Plan land use designation and regional housing goals. • Provide affordable housing units in accordance with the Contra Costa County Housing Element (2014). • Locate housing in close proximity to transit in order to reduce vehicle miles traveled. • Provide housing with a variety of floor plans and unit types to enhance the economic viability of the development for long-term sustainability.

In this scenario, the existing buildings and structures associated with the former Palmer School that are currently on the project site would remain, the off-site improvements (frontage sidewalk, driveway curb, gutter improvements) would not occur, the trees would not be removed or impacted, and grading would not take place. Under this alternative, the zoning for the site would remain as Multiple Family Residential (M-17), Multiple Family Residential (M-29), and Single Family Residential (R-15). It is assumed that the existing buildings would remain vacant and no educational land use activities would occur. 4.3.1 - Impact Analysis The No Project, No Build Alternative would avoid the proposed project’s less than significant impacts with mitigation, as well as the need to implement any mitigation measures, associated with air quality, biological resources, cultural resources and tribal cultural resources, geology and soils, greenhouse gas emissions, hydrology and water quality, noise, public services and recreation, and transportation. However, the vacant buildings would pose the potential need for regular police service and potential fire protection services to protect against likely vandalism, use by transients, and continuing hazards related to deteriorating conditions common in vacant buildings. Because this alternative would likely result in fewer calls for service in comparison with the proposed project because the site would be vacant, it would result in reduced impacts compared to the proposed project. The No Project, No Build Alternative would avoid the proposed project’s less than significant impacts without mitigation associated with aesthetics, light, and glare, air quality, biological resources, energy, geology and soils, greenhouse gas emissions, hydrology and water quality, noise, population and housing, transportation, utilities and service systems, and wildfire.

In addition, on-site soils exhibiting evidence of contamination from petroleum releases from the 50-gallon underground storage tank (UST) that was removed from the site approximately 25 years ago and/or any potential previously unidentified subgrade structures of environmental concern (e.g., USTs), would not be removed. If the existing structures were to remain without further activity, they would ultimately deteriorate to a ruin. Hazardous conditions related to continued degradation of the structures, and the potential for transients to utilize the vacant buildings, would exacerbate blight conditions, and urban design requirements would not be met. As these potentially hazardous materials and potentially hazardous conditions would not be removed from the project site, the No Project, No Build Alternative would result in greater impacts related to hazards and hazardous materials in comparison with the proposed project; however, these impacts would be less than significant. Although the No Project, No Build Alternative would not result in any construction activities on the project site, this alternative would result in greater impacts than the proposed project associated with land use and planning. Under this alternative, the site would not be developed with 125 townhouse condominiums. The site would remain vacant and underutilized, and as such, the No Project, No Build Alternative would not be consistent with the General Plan goals and policies related to providing residences in unincorporated area of the County, nor would the project site be rezoned to achieve consistency with the Contra Costa County Zoning Ordinance. This alternative would not be consistent with other applicable goals and policies of the General Plan adopted for various land use planning reasons, including the purpose of avoiding or mitigating an environmental impact or fully utilizing land uses to contribute to economic growth. As the site would not be developed with 125 townhouse condominium units, including affordable units, in close proximity to the Pleasant Hill/Contra Costa Centre Bay Area Rapid Transit (BART) station, this alternative would not be consistent with Goal 3-E, which encourages higher residential densities near major transportation hubs and job centers, Policy 3-22, which requires the creation of housing opportunities for all income levels, and Policy 3-8, which encourages the infilling of already developed areas. Therefore, the No Project, No Build Alternative would result in significant and unavoidable impacts related to land use and planning in comparison with the proposed project. 4.3.2 - Conclusion Except for hazards and hazardous materials and land use and planning, the No Project, No Build Alternative would avoid all the proposed project’s less than significant impacts and less than significant impacts with mitigation described in Sections 3.1 through 3.16, as well as avoid the need to implement any mitigation measures. The No Project, No Build Alternative would result in greater impacts than the proposed project associated with hazards and hazardous materials; however, this impact would remain less than significant. Because this alternative would result in vacant and underutilized parcels inconsistent with land use and planning, it would result in a significant and unavoidable impact with respect to land use, which is a greater impact in comparison with the proposed project.

Instead, the existing buildings on the project site would remain vacant and no educational land use activities would occur. As such, the No Project, No Build Alternative would not meet the objectives of developing an appropriate mix of multi-family units (including affordable units) that meets regional housing goals, providing affordable housing units in accordance with the Contra Costa County Housing Element (2014), locating housing in close proximity to transit in order to reduce vehicle miles traveled, providing housing with a variety of floor plans and unit types to enhance the economic viability of the development for long-term sustainability, replacing an obsolete private school with new market rate and affordable for-sale townhouse condominium homes consistent with the General Plan and surrounding neighborhood, and establishing physical and social connections between Jones and Oak Roads by building safe, private streets, walkable landscaped open spaces including stormwater management and green building components. 4.4 - Alternative 2–Reopening the Palmer School Under the Reopening the Palmer School Alternative, the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, and no new development would take place on the project site. The school would resume operations at the same level and intensity as at the time of school closure in June 2020. Under this alternative, the zoning for the site would remain as Multiple Family Residential (M- 17), Multiple Family Residential (M-29), and Single Family Residential (R-15). Reopening the Palmer School would require compliance with and obtaining of approvals/permits from the California Department of Education and/or appropriate local agencies. This process would include obtaining a land use permit from Contra Costa County. Because the site was operating as a private school as recently as June 2020 and had to adhere to applicable federal, State, and local regulations for a school (including an annual inspection through the Office of the State Fire Marshall and the Private School Building Safety Act of 1986)1,2 it is assumed that no hazardous material abatement or seismic retrofit would be necessary to reopen the school. 4.4.1 - Impact Analysis Aesthetics, Light, and Glare As noted in Section 3.1, Aesthetics, the proposed project’s impacts related to scenic vistas, scenic resources, and the existing visual character and quality of public views of the site and its 1 California Legislative Information. 2019.

Impacts with respect to lighting and glare would be less than significant with mitigation. The Reopening the Palmer School Alternative assumes the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, no new development would take place on the project site, and no new land uses would be introduced. This alternative would not result in a change on the views, visual character, nighttime lighting, or daytime glare either on-site or off-site compared to existing conditions. Therefore, the Reopening the Palmer School Alternative would result in less impacts on aesthetics, light, and glare as compared to the proposed project; impacts would be less than significant without mitigation with respect to scenic vistas, scenic resources, the existing visual character, and quality of public views of the site, lighting and glare, and cumulative impacts. Air Quality As noted in Section 3.2, Air Quality, the proposed project’s impacts related to air quality would be less than significant without mitigation with respect to air quality management plan consistency and exposure to objectionable odors during construction and operation. The proposed project’s impacts related to criteria pollutant emissions would be less than significant with mitigation for construction and less than significant without mitigation for operations. The proposed project’s impacts related to sensitive receptors’ exposure to toxic air contaminant concentrations would be less than significant with mitigation during construction and would be less than significant during operation; cumulative impacts would be less than significant with mitigation. Construction The Reopening the Palmer School Alternative assumes the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, and no new development would take place on the project site. Because the Reopening the Palmer School Alternative would not require construction, there would be no impact related to air quality during construction (i.e., criteria pollutant emissions and sensitive receptors’ exposure to toxic air contaminant concentrations). Though the existing buildings could contain asbestos, there would be no demolition of buildings so exposure to these materials would be limited. There would be no impact related to exposure to objectionable odors during construction. Because the Reopening the Palmer School Alternative would result in no construction-related impacts, there would be less impacts as compared to the proposed project. Operation As described in Impact AIR-1, in Section 3.2, Air Quality, a measure for determining whether a use supports the primary goals of the 2017 Clean Air Plan is if a use would result in an increase in the frequency or severity of existing air quality violations, cause or contribute to new violations, or delay timely attainment of air quality standards or the interim emission reductions specified in the Air Quality Plans (AQPs). The development of the AQP is based, in part, on the land use pattern envisioned by local general plans of the various cities and counties that constitute the Air Basin. Because the school was operational until its closure in June 2020, it was included in the growth Contra Costa County–Oak Road Townhouse Condominiums Project Alternatives to the Proposed Project Draft EIR 4-8 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec04-00 Alternatives.docx assumptions forming the basis for the AQP. As such, the Reopening the Palmer School Alternative would be consistent with the air quality management plan. Therefore, this alternative would result in similar impacts to air quality management plan consistency when compared to the proposed project. Impact AIR-2 (Table 3.2-11) provides the operational emissions for the Palmer School, none of which are above Bay Area Air Quality Management District (BAAQMD) thresholds. The Transportation Analysis Memorandum prepared by Hexagon Transportation Consultants for the proposed project includes trip rates associated with the Palmer School (1,521 daily trips with 337 trips during the AM peak-hour and 96 trips during the PM peak-hour). In addition, as identified in the Tran sportation Analysis Memorandum, the studied intersection near the project site which currently experiences the greatest level of vehicle traffic is the intersection of Oak Road and Treat Boulevard, which experiences an estimated 6,016 vehicle trips during the AM peak-hour and 5,142 vehicle trips during the PM peak-hour. Therefore, conservatively assuming all peak-hour traffic generated by this alternative would travel through the intersection of Oak Road and Treat Boulevard, this alternative would not cause any intersections near the project site to experience traffic volumes of 44,000 vehicles per hour and would not cause an exceedance of the carbon monoxide (CO) screening criteria. Therefore, similar to the proposed project, this alternative would have a less than significant impact on criteria pollutant emissions during operation without mitigation. The alternative assumes the currently closed school would reopen and resume operations as a private K-8 school at the same intensity as previously operated. Operation of a school would likely not generate objectionable odors. In addition, public records retrieved from the BAAQMD show that no odor complaints were filed for this location between January 1, 2018, and the time at which this analysis was prepared during which time the school was operational. Therefore, it is not anticipated that reopening the Palmer School would result in the generation of objectionable odors which may affect a substantial number of people. Therefore, the Reopening the Palmer School Alternative would result in similar impacts related to objectionable odors as compared to the proposed project and impacts would be less than significant. Biological Resources As noted in Section 3.3, Biological Resources, the proposed project would result in no impacts with respect to sensitive and natural communities or riparian habitat and wetlands and jurisdictional features and would not conflict with an adopted Habitat Conservation Plan. The proposed project would result in less than significant impacts without mitigation with respect to fish and wildlife movement corridors and cumulative impacts. The proposed project’s impacts related to special- status wildlife species and conflict with local policies or ordinances would be reduced to less than significant with mitigation incorporated. The Reopening the Palmer School Alternative assumes the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, no new development would take place on the project site, and no new land uses would be introduced. Similar to the proposed project, no impacts would occur with respect to sensitive and natural communities or riparian habitat, wetlands and jurisdictional features, and conflicts with an adopted Habitat Conservation Plan.

Because the Reopening the Palmer School Alternative would not require construction (including ground disturbance and building demolition) there would a less than significant impact without mitigation related to special-status wildlife. In addition, none of the existing trees would be removed, and there would be a less than significant impact without mitigation related to conflict with local policies or ordinances resulting in reduced impacts related to biological resources as compared to the proposed project. Cultural Resources and Tribal Cultural Resources As noted in Section 3.4, Cultural Resources and Tribal Cultural Resources, the proposed project’s impacts related to historic resources, archaeological resources, disturbance to human remains, and tribal cultural resources, and cumulative impacts would be reduced to less than significant with mitigation incorporated. The Reopening the Palmer School Alternative assumes the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, no new development would take place on the project site, and no new land uses would be introduced. Because the Reopening the Palmer School Alternative would not require construction or associated ground disturbance, there would be no impact related to historic resources, archaeological resources, disturbance to human remains, tribal cultural resources, and cumulative impacts resulting in reduced impacts related to cultural resources as compared to the proposed project. Energy As noted in Section 3.5, Energy, the proposed project would result in energy consumption during construction and at project operation. However, the proposed project’s impacts related to energy would be less than significant without mitigation with respect to energy use during construction and at operation, conflicting with a plan for renewable energy or energy efficiency, and cumulative impacts. This alternative would require energy usage by students and staff during operation, which would consist primarily of building energy consumption and vehicle fuel consumption. Because this alternative would result in greater vehicle activity than was estimated for the proposed project,3 there would be greater impacts related to vehicle energy consumption as compared to the proposed project. Nonetheless, the continued implementation of various State agreements and legislation, such as the State’s Light-Duty Greenhouse Gas Emissions Standards, would contribute to increasingly fuel-efficient vehicles utilized during operation. In addition, Senate Bill (SB) 100 would ensure that building electricity is sourced from increasingly renewable and carbon-free sources through the year 2045. Therefore, the Reopening the Palmer School Alternative would result in greater impacts related to energy at operation as compared to the proposed project; however, impacts would be less than significant without mitigation. 3 Hexagon Transportation Consultants, Inc. 2021.

The proposed project’s cumulative impact would be less than significant without mitigation. The proposed project’s impacts related to exposure of persons, structures, or improvements to seismic- and soil-related hazards, soil erosion or the loss of topsoil, paleontological resources, and cumulative resources would be reduced to less than significant levels with mitigation incorporated. The Reopening the Palmer School Alternative assumes the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, no new development would take place on the project site, and no new land uses would be introduced. Because the Reopening the Palmer School Alternative would not require construction or associated ground disturbance, there would be no impact with respect to wastewater disposal systems, exposure of persons, structures, or improvements to seismic- and soil- related hazards, soil erosion or the loss of topsoil, paleontological resources, or any cumulative impacts during construction. Accordingly, this alternative would result in reduced impacts related to geology and soils (with respect to soil erosion or the loss of topsoil and impacts to paleontological resources) as compared to the proposed project. At operation, similar to the proposed project, there would be no impact with respect to soil erosion or topsoil loss or wastewater disposal systems. Because the site was operating as a private school as recently as June 2020 and had to adhere to applicable federal, State, and local regulations for a school (including an annual inspection through the Office of the State Fire Marshall and the Private School Building Safety Act of 1986), and would continue to do so once the school reopens, it is assumed that no seismic retrofit would be necessary to reopen the school. Therefore, there would be a less than significant impact without mitigation with respect to exposure of persons, structures, or improvements to seismic- and soil-related hazards and cumulative impacts resulting in reduced impacts related to geology and soils as compared to the proposed project. Greenhouse Gas Emissions As noted in Section 3.7, Greenhouse Gas Emissions, the proposed project’s impacts with respect to greenhouse gas (GHG) emissions, GHG emissions reduction plan consistency, and cumulative impacts would be less than significant. Differing from the proposed project, the Reopening the Palmer School Alternative would not involve any construction. Therefore, there would be reduced impacts related to GHG emissions under this alternative during construction and impacts would be less than significant without mitigation. At operation, there would be greater impacts related to GHG emissions compared with the proposed project due to the increase in building operation emissions and vehicle traffic as compared to the proposed project, which would require the implementation of mitigation measures such as on-site measures and/or the purchase of carbon credits; impacts would be less than significant with mitigation.

SB 100 would additionally ensure that building electricity is sourced from increasingly renewable and carbon-free sources through the year 2045. In addition, this alternative’s GHG emissions would need to be mitigated to less than significant levels, which would demonstrate consistency with the 2030 GHG legislative reduction target codified in SB 32. As such, this alternative would result in similar impacts related to consistency with a plan, policy, or regulation adopted for the purpose of reducing GHG emissions. Hazards and Hazardous Material As noted in Section 3.8, Hazards and Hazardous Materials, the proposed project would have no impact related to proximity to a public airport safety hazard. The proposed project’s impacts related to hazardous materials upset risk, hazardous emissions proximate to a school, being located on a listed hazardous materials site, proximity to public airport safety hazard, emergency response and evacuation, wildland fires, and cumulative impacts would be less than significant without mitigation. The proposed project’s impacts related to the release of hazardous materials during excavation and construction from potentially contaminated soils, soil vapor, and on-site wells, would be reduced to less than significant levels with mitigation incorporated. The Reopening the Palmer School Alternative assumes the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, no new development would take place on the project site, and no new land uses would be introduced. Similar to the proposed project, this alternative’s impacts related to hazardous materials upset risk, hazardous emissions proximate to a school, being located on a listed hazardous materials site, proximity to public airport safety hazard, emergency response and evacuation, wildland fires, and cumulative impacts would be less than significant without mitigation. With respect to hazardous emissions proximate to a school, the proposed project would not be expected to include industrial or retail development that involves hazardous materials such as gas stations, paint stores, or auto parts stores. No hazardous materials other than small containers of conventional cleaning supplies and insecticides would be utilized on-site in accordance with applicable local, State, and federal regulations. Because the Reopening the Palmer School Alternative would not result in any construction activities on the project site, this alternative would not include mitigation requiring abatement or removal of ACM and LBP. Though the existing buildings could contain ACM and LBP, there would be no demolition of buildings and these buildings would be required to be kept in good repair, so exposure to these materials would be limited. In addition, on-site soils exhibiting evidence of contamination from petroleum releases from the 50-gallon UST that was removed from the site approximately 25 years ago and/or previously unidentified subgrade structures of environmental concern (e.g., USTs), would not be removed. Because the site was operating as a private school as recently as June 2020 and had to adhere to applicable federal, State, and local regulations for a school (including an annual inspection through the Office of the State Fire Marshall) and would continue to do so once the school reopens, it is assumed that potential adverse effect is less than significant. However, since the potential presence of these materials has not been verified through testing, impacts would be considered greater than the proposed project (which would require testing and possible abatement).

The proposed project’s impacts related to erosion/siltation, additional sources of polluted runoff, exceedance of storm drainage capacity resulting in flooding, and impedance of flood flows from alterations to the existing drainage pattern of the site would be reduced to less than significant levels with mitigation incorporated. The Reopening the Palmer School Alternative assumes the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, no new development would take place on the project site, and no new land uses would be introduced. Because the Reopening the Palmer School Alternative would not require construction or associated ground disturbance, there would be no impact with respect to erosion/siltation, additional sources of polluted runoff, exceedance of storm drainage capacity resulting in flooding, impedance of flood flows from alterations to the existing drainage pattern, surface and groundwater quality, groundwater supply/recharge, risk of pollutant release due to project site inundation, water quality control or sustainable groundwater management plans consistency, and cumulative impacts during construction resulting in reduced impacts related to hydrology and water quality compared to the proposed project. Currently, on-site drainage and storm runoff generally sheet flows across the site or is captured by on- site small drainage inlets connected by underground storm drainpipes which is then discharged into the existing storm drain facilities in Jones Road or Oak Road. Based on field observation and record drawings, it appears most of the existing on-site drainage is discharged or conveyed via underground storm drains to the existing 30-inch storm drains in Oak Road. At operation, this alternative would utilize the existing storm drainage system. It would also include the same amount of impervious surfaces compared to existing conditions and would continue to abide by existing applicable federal, State, and local regulations to minimize stormwater runoff and pollution. Because this drainage system is already in place, the alternative would result in less than significant without mitigation impacts with respect to erosion/siltation, additional sources of polluted runoff, exceedance of storm drainage capacity resulting in flooding, impedance of flood flows from alterations to the existing drainage pattern, surface and groundwater quality, groundwater supply/recharge, risk of pollutant release due to project site inundation, water quality control or sustainable groundwater management plans consistency, and cumulative impacts. Therefore, the Reopening the Palmer School Alternative would result in reduced impacts related to hydrology and water quality as compared to the proposed project and impacts would be less than significant without mitigation. Land Use and Planning As noted in Section 3.10, Land Use and Planning, the proposed project’s impacts related to physically dividing an established community, conflicting with applicable plans, policies, or regulations adopted for the purpose of avoiding or mitigating an environmental effect, and cumulative impacts would be less than significant without mitigation.

All buildings and structures would remain in place, no trees would be removed, no new development would take place on the project site, and no new land uses would be introduced. Similar to the proposed project, this alternative would not physically divide and established community. Although this alternative would utilize existing educational resources, it would not maximize the use of the 5.94-acre site or the facilities and would not achieve the majority of applicable General Plan goals. Because this alternative would not develop 125 townhouse condominiums, this alternative would not be consistent with the General Plan goals and policies related to providing residences in unincorporated area of the County, nor would the project site be rezoned to achieve consistency with the Contra Costa County Zoning Ordinance. This alternative would not be consistent with other applicable goals and policies of the General Plan adopted for various land use planning reasons, including the purpose of avoiding or mitigating an environmental impact. As the site would not be developed with multi-family residential units, including affordable units, in close proximity to the Pleasant Hill/Contra Costa Centre BART station, this alternative would not be consistent with Goal 3-E, which encourages higher residential densities near major transportation hubs and job centers, Policy 3-22, which requires the creation of housing opportunities for all income levels, and Policy 3-8, which encourages the infilling of already developed areas. Therefore, this alternative would conflict with several applicable land use plans, policies, and regulations and would result in greater impacts related to land use and planning than the proposed project; however, impacts would be less than significant. Noise As noted in Section 3.11, Noise, the proposed project would result in noise from construction activities and operational noise from mechanical ventilation equipment and increased traffic on local roadway segments in the project vicinity. There would be no impact associated with excessive noise levels from airport activity. The proposed project’s impacts would be less than significant without mitigation with respect to substantial noise increases in excess of standards (during operation only), groundborne vibration, groundborne noise levels, excessive noise levels from airport activity, and cumulative impacts. The proposed project’s impacts would be less than significant with mitigation with respect to noise levels that would conflict with any land use plan, policy, or regulation, and impacts related to substantial noise increase in excess of standards during construction. The Reopening the Palmer School Alternative assumes the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, no new development would take place on the project site, and no new land uses would be introduced.

At operation, the school uses would result in potential noise impacts from operations similar to when the school was in operation. Operational noise sources include mechanical ventilation Contra Costa County–Oak Road Townhouse Condominiums Project Alternatives to the Proposed Project Draft EIR 4-14 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec04-00 Alternatives.docx equipment operations, parking lot activity and outdoor recreational use activities associated with typical school land uses. Reintroduction of these noise sources to the project site could potentially result in a substantial increase in ambient noise levels as measured at adjacent noise-sensitive residential land uses compared to existing conditions experienced with the vacant and unused school. However, the noise level is expected to be similar to the noise level that would be generated by residents of 125 townhouse condominium units and associated parking lots and outdoors activities. Operational noise impacts would be similar to the proposed project. Population and Housing As noted in Section 3.12, Population and Housing, the proposed project would have no impact with respect to population/housing displacement and a less than significant impact without mitigation with respect to population growth and cumulative impacts. The alternative would not include the development of new housing, and the two existing residential units that are occupied by the property owner ’s family members serving as caretaker and security for the property, would remain on-site. Similar to the proposed project, this alternative would have no impact with respect to population/housing displacement and a less than significant impact without mitigation with respect to population growth and cumulative impacts and this alternative would result in similar impacts related to population and housing as compared to the proposed project. Public Services and Recreation As noted in Section 3.13, Public Services and Recreation, the proposed project may result in an increased demand for fire protection facilities and police protection facilities during construction. At operation, the proposed project would add an estimated 357 persons to the County’s population, and in turn, could result in an increase in calls for fire protection, emergency services, or police protection. However, the proposed project’s impacts related to fire protection facilities, police protection facilities, school facilities, library facilities, and cumulative impacts would be less than significant without mitigation. Impacts related to the provision of parks and recreational facilities would be less than significant with mitigation. Because the Reopening the Palmer School Alternative would not require construction or associated ground disturbance, there would be no impact with respect to increased demand for fire and police protection services during construction nor construction impacts related to provision of on-site recreational facilities. Similar to the proposed project, there would be no impact with respect to the need for new or altered school, library, or park facilities. Because there would be no construction- related impacts, this alternative would result in reduced impacts related to public services compared to the proposed project. Under this alternative, the school would return to its pre-closure enrollment of approximately 370- 400 students, employing approximately 45-52 staff members. School hours would follow pre-closure hours and would be open Monday through Friday. Because the service providers recently provided services (the school was closed in June 2020) to this site, and reopening the school would not result in additional students or staff, this alternative would not result in the need for new or altered fire or police protection facilities, school facilities, library facilities, or park facilities; cumulative impacts Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Alternatives to the Proposed Project FirstCarbon Solutions 4-15 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec04-00 Alternatives.docx would be less than significant, and this alternative would result in a less than significant impact with respect to these public services during operation. Overall, because this alternative would not require additional public services associated with construction, it would result in reduced impacts related to public services as compared to the proposed project. Transportation As noted in Section 3.14, Transportation, the proposed project’s impacts related to bicycle, pedestrian facilities, and transit facilities, Vehicles Miles Traveled (VMT), roadway safety hazards, emergency access, and cumulative impacts would be less than significant without mitigation. The Reopening the Palmer School Alternative assumes the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, no pedestrian, bicycle, or transit facilities would be removed, no new development would take place on the project site, and no new land uses would be introduced. Because the alternative would include school uses on a site previously utilized for this purpose and would not include the removal of any existing pedestrian, bicycle, or transit facilities, and because of the site’s proximity and connectivity of these facilities to the project site, similar to the proposed project, this alternative would not conflict with a program plan, ordinance, or policy of the circulation system including transit, bicycle, and pedestrian facilities. Similar to the proposed project, this alternative would be expected to result in a less than significant VMT impact because the project site is located within 0.5 mile of an existing major transit stop or an existing stop along a high-quality transit corridor.4 Impacts would also be less than significant without mitigation with respect to roadway safety hazards and emergency access as this site was utilized for the same land use up until June 2020, and the alternative would follow all applicable regulations and policies. Cumulative impacts would also be less than significant without mitigation. In conclusion, the Reopening the Palmer School Alternative would result in similar, less than significant impacts related to transportation as compared to the proposed project. Utilities and Service Systems As noted in Section 3.15, Utilities and Service Systems, the proposed project could result in up to 357 persons at the project site, and in turn, would result in an increase in the demand for water, wastewater, and solid waste collection services. Development of the site would also require the construction of new stormwater facilities and power and telecommunication facilities. The proposed project’s impacts related to water supply or conveyance facilities, wastewater treatment or conveyance facilities, stormwater drainage facilities, natural gas, electric power, telecommunications facilities, landfill capacity, consistency with solid waste regulations, and cumulative impacts would be less than significant without mitigation. 4 Hexagon Transportation Consultants, Inc. 2021.

All buildings and structures would remain in place, no trees would be removed, no new development would take place on the project site, and no new land uses would be introduced. Under this alternative, the school would return to its pre-closure enrollment of approximately 370- 400 students, employing approximately 45-52 staff members. The utility providers and conveyance systems that served the project site previously (prior to June 2020) would continue to serve the project site and reopening the school would not result in additional students or staff. Therefore, this alternative would not result in the need for new or altered water supply or conveyance facilities, wastewater treatment or conveyance facilities, stormwater drainage facilities, natural gas, electric power, telecommunications facilities, additional landfill capacity, and the alternative would adhere to all applicable solid waste regulations; cumulative impacts would be less than significant. This alternative would result in a less than significant impact with respect to these utilities and service systems during operation and cumulative impacts would be less than significant. Thus, similar to the proposed project, impacts under this alternative would be less than significant without mitigation. Wildfire As noted in Section 3.16, Wildfire, the proposed project’s impacts related to impairment of an emergency response plan or emergency evacuation plan, exposing project occupants to pollutant concentrations from wildfire, installation or maintenance of infrastructure that exacerbates fire risk, flooding and landslide hazards due to post-fire slope instability or drainage changes, and cumulative impacts would be less than significant without mitigation. The Reopening the Palmer School Alternative assumes the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, no pedestrian, bicycle, or transit facilities would be removed, no new development would take place on the project site, and no new land uses would be introduced. As discussed above under Section 3.13, Public Services and Recreation, the alternative proposed project would be adequately served by police and fire services, which would include respective evacuation or emergency vehicle access, and adhere to all applicable policies. This alternative would be required to comply with an annual inspection through the Office of the State Fire Marshall and County Emergency Operations Plan (EOP), ensuring efficient response to emergency incidents associated with emergencies affecting the County. Therefore, this alternative would result in similar impacts as compared to the proposed project related to emergency response and emergency evacuation and impacts would be less than significant without mitigation. Similar to the proposed project, the site is relatively flat, not located near steep slopes susceptible to wildfire, mostly surrounded by urban uses, and lacking in woodlands that could provide fuel load for wildfire. Therefore, this alternative would result in similar impacts as compared to the proposed project related to exposing project occupants to pollutant concentrations from wildfire, installation or maintenance of infrastructure that exacerbates fire risk, or flooding and landslide hazards due to post-fire slope instability or drainage changes and cumulative impacts. Thus, similar to the proposed project, impacts under this alternative would be less than significant without mitigation.

This alternative would lessen the severity of the proposed project’s less than significant with mitigation impacts associated with respect to aesthetics, biological resources, cultural and tribal cultural resources, geology and soils, hazards and hazardous materials, hydrology and water quality, and public services and recreation. This alternative would result in a greater, although still less than significant, impact related to energy and land use and planning. With respect to GHG emissions, this alternative would require mitigation where the proposed project would not, which would result in a greater impact than the proposed project. This alternative would result in similar or greater impacts with respect to noise. The Reopening the Palmer School Alternative would not meet any of the project objectives because the project site would not be developed with 125 multi-family residential units, including affordable units. Instead, the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, and no new development would take place on the project site. The school would resume operations at the same level as at the time of school closure in June 2020. As such, the Reopening the Palmer School Alternative would not meet the objectives of (1) developing an appropriate mix of multi-family units (including affordable units) that meets regional housing goals, (2) providing affordable housing units in accordance with the Contra Costa County Housing Element (2014), (3) locating housing in close proximity to transit in order to reduce vehicle miles traveled, (4) providing housing with a variety of floor plans and unit types to enhance the economic viability of the development for long-term sustainability, (5) replacing an obsolete private school with new market rate and affordable for-sale townhouse condominium homes consistent with the General Plan and surrounding neighborhood, (6) establishing physical and social connections between Jones and Oak Roads by building safe, private streets, walkable landscaped open spaces including stormwater management and green building components, (7) providing on-site open space amenities for future residents, and (8) phase development to allow for managed, orderly, and economically viable growth. This alternative would partially meet the objective related to retaining the architectural and visual character of the neighborhood because the on-site trees would not be removed. 4.5 - Environmentally Superior Alternative The qualitative environmental effects of each alternative in relation to the proposed project are summarized in Table 4-1. The significant conclusion for each alternative is also identified in the table. Table 4-2 presents a comparison of the alternative's ability to meet project objectives. As explained in detail above, because there are no significant and unavoidable impacts, the comparison contained in Table 4-1 and Table 4-2 and the subsequent discussion are provided for discussion purposes only.

If the No Project Alternative is the environmentally superior alternative, the EIR must also identify an environmentally superior alternative from among the other alternatives. As shown in Table 4-1, the No Project, No Build Alternative would avoid the proposed project’s less than significant impacts associated with mitigation for nine environmental topic areas, as well as the need to implement any mitigation measures. The No Project, No Build Alternative would avoid the proposed project’s less than significant impacts without mitigation associated with six environmental Contra Costa County–Oak Road Townhouse Condominiums Project Alternatives to the Proposed Project Draft EIR 4-20 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec04-00 Alternatives.docx topic areas. Lastly, the No Project, No Build Alternative would result in greater impacts than the proposed project associated with one environmental topic areas (though it would still be less than significant), and a greater, significant unavoidable impact in one environmental topic area. As shown in Table 4-2, this alternative would not meet any of the project objectives. As shown in Table 4-1, the Reopening the Palmer School Alternative would reduce the proposed projects less than significant impacts with eight environmental topic areas, would result in similar impacts in five topic areas, and would result in greater impacts in three topic areas. This alternative would not result in any significant and unavoidable impacts. Because this alternative would lessen several of the proposed project’s impacts and would not result in significant and unavoidable impacts, it would be the environmentally superior alternative. As shown in Table 4-2, this alternative would meet almost none of the project’s objectives. It would partially meet the objective related to retaining the architectural and visual character of the neighborhood because none of the on-site trees would be removed. 4.6 - Alternatives Rejected from Further Consideration CEQA Guidelines 15126.6(c) requires an EIR to discuss alternatives that were initially considered but rejected from further consideration. 4.6.1 - Develop According to Existing General Plan by Different Applicant Alternative A Develop According to Existing General Plan by Different Applicant Alternative, which would include the development of 140 residential units, was considered. There is no current proponent for development of a higher density residential project, and it is entirely speculative that any proponent would come forward. This alternative was rejected from further consideration because it would not avoid or substantially lessen the proposed project’s significant effects as it would be very similar to the proposed project. This alternative would meet most of the project objectives, although in some cases to a lesser extent than the proposed project. As this alternative would include the development of 15 more residential units, this alternative may provide fewer walkable landscaped open spaces and on- site open space amenities for future residents. As this alternative would include the development of 15 more residential units, this alternative may not retain the architectural and visual character of the neighborhood by building 3-story townhouse condominiums with roof-deck elements on selected homes fronting Oak Road and providing replacement landscaping that will mature over time. Based on Section 15126.6 of the CEQA Guidelines, this alternative was rejected as infeasible (as there is no current proponent) and unable to meet the objectives of the proposed project. 4.6.2 - Reduced Scale Alternative A Reduced Scale Alternative, which would result in a 25 percent reduction in development, was considered. This alternative would include development of 94 residential units, which would result in a lower density than the proposed project. There is no current proponent for development of a lower density residential project, and it is entirely speculative that any proponent would come forward. This alternative was rejected from further consideration because it would not entirely avoid or substantially lessen the proposed project’s significant effect. This alternative would meet most of Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Alternatives to the Proposed Project FirstCarbon Solutions 4-21 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec04-00 Alternatives.docx the project objectives, although in some cases to a lesser extent than the proposed project. As this alternative would include the development of 31 less residential units, this alternative may not meet the goal of retaining the architectural and visual character of the neighborhood by building 3-story townhouse condominiums with roof-deck elements, and would meet the goal of locating housing in close proximity to transit in order to reduce vehicle miles traveled to a lesser degree than the proposed project as density would be lower resulting in fewer people utilizing adjacent public transit. Based on Section 15126.6 of the CEQA Guidelines, this alternative was rejected as infeasible (as there is no current proponent) and unable to meet the objectives of the proposed project. 4.6.3 - Alternative Location CEQA Guidelines Section 15126.6(f)(2) sets forth considerations to be used in evaluating an alternative location. The section states that the “key question” is whether any of the significant effects of the project would be avoided or substantially lessened by relocating the project. The CEQA Guidelines identify the following factors that may be taken into account when addressing the feasibility of an alternative location: 1) Site suitability 2) Economic viability 3) Availability of infrastructure 4) General Plan consistency 5) Other plans or regulatory limitations 6) Jurisdictional boundaries 7) Whether the project applicant can reasonably acquire, control, or otherwise have access to the alternative site The CEQA Guidelines establishes that only locations that would accomplish this objective should be considered as alternative locations for the project. During the alternatives review process, the County conducted a review of available land near Interstate 680 and in close proximity to the Pleasant Hill/Contra Costa Centre BART station that could support a project similar in size and type as the proposed project, and that had an appropriate General Plan land use designation and zoning classification to allow for multi-family residential land uses. An appropriate alternative vacant site was not identified within the County limits in the general vicinity. Furthermore, CEQA confirms that whether a proponent can reasonably acquire, control, or otherwise have access to an alternative site is a key factor in determining whether an off-site alternative is potentially feasible (State CEQA Guidelines § 15126.6(f)). The County, as lead agency, is therefore not required to select an alternative site for the proposed project. Based on CEQA Guidelines Section 15126.6, a potential alternative location was rejected as infeasible.

As part of this analysis, the Draft Environmental Impact Report (Draft EIR) must also identify (1) significant environmental effects of the proposed project; (2) significant environmental effects which cannot be avoided if the proposed project is implemented; (3) significant irreversible environmental changes which would be involved in the proposed project should it be implemented; (4) growth-inducing impact of the proposed project; (5) mitigation measures proposed to minimize the significant effects; and (6) alternatives to the proposed project. This chapter provides a discussion of other CEQA-mandated topics, including significant unavoidable impacts, growth inducement, and significant irreversible environmental changes which would be involved in the proposed project should it be implemented. Chapter 3, Environmental Impact Analysis, describes the significant environmental effects of the proposed project and provides mitigation measures proposed to minimize significant effects. Chapter 6, Alternatives to the Proposed Project, discusses alternatives to the proposed project. 5.1 - Significant Unavoidable Impacts CEQA Guidelines Section 15126.2(c) requires an EIR to describe significant environmental effects of the proposed project that cannot be avoided if the proposed project were implemented. The proposed project was analyzed for potentially significant impacts related to each of the environmental issues discussed in Sections 3.1 through 3.16. The results of the analysis indicate that the proposed project would not result in any significant and unavoidable impacts. 5.2 - Growth-Inducing Impacts There are two types of growth-inducing impacts that a project may have: direct and indirect. To assess the potential for growth-inducing impacts, the project’s characteristics that may encourage and facilitate activities that individually or cumulatively may affect the environment must be evaluated (CEQA Guidelines § 15126.2(e)). CEQA Guidelines, as interpreted by the County, state that a significant growth-inducing impact may result if the project would: • Induce substantial population growth in an area (for example, by proposing new homes and commercial or industrial businesses beyond the land use density/intensity envisioned in the general plan); • Substantially alter the planned location, distribution, density, or growth rate of the population of an area; or • Include extensions of roads or other infrastructure not assumed in the general plan or adopted capital improvements project list when such infrastructure exceeds the needs of the project and could accommodate future developments. Contra Costa County–Oak Road Townhouse Condominiums Project Other CEQA Considerations Draft EIR 5-2 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec05-00 Other CEQA.docx Direct growth-inducing impacts occur when the development of a project imposes new burdens on a community by directly inducing unplanned population growth or by leading to the construction of additional developments in the same area. Also included in this category are projects that remove physical obstacles to population growth (such as a new road into an undeveloped area or a wastewater treatment plant with excess capacity that could allow additional development in the service area). Construction of these types of infrastructure projects cannot be considered isolated from the development they facilitate and serve. Projects that physically remove obstacles to growth, or projects that indirectly induce growth, may provide a catalyst for future unrelated development in an area such as a new residential community that requires additional commercial uses to support residents. Direct Population Growth The proposed project would develop 125 new townhouse condominium units on the project site. Table 5.2-1 summarizes project-related population growth. As shown in the table, the project would add an estimated 357 persons to the County’s population. This would represent an increase of 0.2 percent relative to the unincorporated population of 174,423. This amount of population growth would be within the General Plan’s 2020 population and dwelling projections for the unincorporated area and, therefore, would not be considered substantial. Furthermore, it would also be within the Association of Bay Area Governments (ABAG) 2020-2040 regional population growth projections. Impacts would be less than significant. Table 5.2-1: Project-Related Population Growth Dwelling Units Persons Per Household Population Growth Population Growth as a Percent of Unincorporated Contra Costa County’s 2021 Population 125 2.85 357 0.2% Notes: Contra Costa County’s 2021 unincorporated population estimated to be 174,423; refer to Table 3.12-1 Source: California Department of Finance 2021; FirstCarbon Solutions (FCS) 2021. Indirect Population Growth The proposed project is exclusively residential; it would not create new permanent employment opportunities. Thus, no indirect population growth from new employment would occur. The project site has been developed since the 1930s and is located within an urbanized area of the unincorporated County. It is served with urban infrastructure and utilities including potable water, sewer, storm drainage, electricity, and natural gas. As such, the proposed project would not remove a barrier of growth through the extension of infrastructure or utilities to an unserved area. Impacts would be less than significant. 5.3 - Significant Irreversible Environmental Changes The environmental effects of the proposed projects are summarized in the Executive Summary and are analyzed in detail in Section 3, Environmental Impact Analysis, of this Draft EIR. Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR Other CEQA Considerations FirstCarbon Solutions 5-3 Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2648/26480017/EIR/3 - Draft EIR/26480017 Sec05-00 Other CEQA.docx As mandated by the CEQA Guidelines, the EIR must address any significant irreversible environmental change that would result from implementation of the proposed project. Specifically, pursuant to the CEQA Guidelines (§ 15126.2(c)), such an impact would occur if: • The proposed project would involve a large commitment of nonrenewable resources; • Primary and secondary impacts would generally commit future generations to similar uses; • The proposed project involves uses in which irreversible damage could result from any potential environmental accidents associated with the project; or • The proposed consumption of resources is not justified (e.g., the project results in the wasteful use of energy). The proposed project consists of the development of new infill multi-family residential uses on a site that currently supports a closed private school. The site is within an urbanized area of unincorporated Contra Costa County adjacent to the Walnut Creek city limits and is zoned for residential use. Construction and demolition debris recycling practices would be expected to allow for the recovery and reuse of building materials such as concrete, lumber, and steel and would limit disposal of these materials, some of which are nonrenewable. Construction of the proposed project would include the consumption of resources that are not replenishable or which may renew so slowly to be considered nonrenewable. These resources would include the following: certain types of lumber and other forest products; aggregate materials used in concrete and asphalt such as sand, gravel, and stone; metals such as steel, copper, and lead; petrochemical construction materials such as plastics; and water. Fossil fuels such as gasoline and oil would also be consumed in the use of construction vehicles and equipment. Consumption of building materials and energy is common to most other development in the region, and commitments of resources are not unique or unusual to the proposed project. Development would not be expected to involve an unusual commitment of nonrenewable resources, nor be expected to consume any resources in a wasteful manner. At operation, day-to-day activities would involve the use of nonrenewable resources such as petroleum and natural gas during operations. The new buildings uses would be required to adhere to the latest adopted edition of the California Building Standards Code, which includes a number of standards that would reduce energy demand, water consumption, wastewater generation, and solid waste generation that would collectively reduce the demand for resources. This would result in the emission and generation of less pollution and effluent and would lessen the severity of corresponding environmental effects. Although the proposed project would result in an irretrievable commitment of nonrenewable resources, the commitment of these resources would not be significantly inefficient, unnecessary, or wasteful. Finally, the proposed project is within walking distance of the Pleasant Hill/Contra Costa Centre Bay Area Rapid Transit (BART) station, the Iron Horse Trail, and the Contra Costa Canal Trail. It is also within walking distance of employment opportunities in Contra Costa Centre. Overall, the proposed project would be expected to result in less consumption of resources than a comparable residential project at the urban edge.

The NOP was prepared to identify the potentially significant effects of the proposed project and was circulated for public review between April 28, 2021, and May 28, 2021. In response to the NOP, no public comments were received related to agricultural resources, forestry resources, or mineral resources, and the lead agency determined that there was no substantial evidence of a potentially significant effect related to Agriculture and Forestry Resources and Mineral Resources.1 Consistent with California Environmental Quality Act (CEQA) Guidelines Section 15128, this chapter provides a brief description of topics found to have no potential impact, or a less than significant impact, based, in part, on the NOP, the NOP public comments received, and/or more detailed analysis conducted as part of the preparation of this Draft EIR. 6.2 - Effects Found not to be Significant 6.2.1 - Agriculture and Forestry Resources No agricultural land or forestland currently exist on the project site. The Contra Costa County General Plan (General Plan) designates the site as Multiple-Family Residential–High-Density (MH), and is zoned for residential uses only including Single-Family Residential (R-15), and Multiple-Family Residential (M-17 and M-29) on the County’s Zoning Map. The site is mapped as “Urban and Built-Up Land” by the by the California Department of Conservation Farmland Mapping and Monitoring Program,2 and is not under a Williamson Act Contract.3 In addition, the General Plan Conservation Element Figure 8-2 does not delineate the project site as an Important Agricultural Area.4 As such, construction and operation of the proposed project would not result in the conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide Importance to non-agricultural uses, or result in the loss or conversion of forestland to non-forest uses. The proposed project would not conflict with any zoning for agricultural use or a Williamson Act Contract, or any zoning for forestland or timberland. Therefore, no impact related to agriculture or forestry resources would occur. 1 This Effects Found not to be Significant Chapter is limited to entire topical areas found to be less than significant. In some instances, throughout this document, specific impacts that were found to be less than significant are nonetheless included in the Draft EIR topical sections (Sections 3.1 through 3.16) for purposes of clarity and to facilitate the readers’ understanding of the overall environmental impact within the topical area. 2 California Department of Conservation. 2016.

DCD is the lead agency for preparation of the environmental impact report (EIR) for this project and is issuing this Notice of Preparation pursuant to Section 15082 of the California Environmental Quality Act (CEQA) Guidelines. PROJECT LOCATION The project site consists of approximately 5.94 acres encompassing numerous parcels (Assessor's Parcel Numbers: 172-012-001, 172-012-007, 172-012-025, 172-012-026, 172-012- 021, 172-012-008, 172-012-023, and 172-012-020) in unincorporated central Contra Costa County, adjacent to the City of Walnut Creek. The site is addressed as 2740 Jones Road, which is located southeast of the intersection of Interstate 680 and Treat Boulevard. PROJECT DESCRIPTION The project is requesting approval of a rezoning of the project site to a Planned Unit District (P-1), subdivision of the project site into 19 residential lots, and a development plan to allow the following: • Demolition of the existing improvements (buildings, foundations, asphalt, concrete, fence poles, landscaping); • Removal of 74 onsite trees, relocation of one valley oak tree, and preservation of six off-site trees; John Kopchik Director Aruna Bhat Deputy Director Jason Crapo Deputy Director Maureen Toms Deputy Director Amalia Cunningham Assistant Deputy Director Department of Conservation and Development 30 Muir Road Martinez, CA 94553 Phone:1-855-323-2626 Page 2 of 3 • Construction of 19 three-story buildings, 45 feet in height, on 129,373 square feet (292,965 total gross square feet); • Installation of approximately 64,686 square feet of landscaped areas; • 319 auto parking spaces (278 onsite spaces and 41 street frontage spaces); • Internal streets, courts, walkways, and drainage improvements; • Off-site improvements including installation of parking stalls along Oak Road and Jones Road; • Grading of approximately 9,300 cubic yards of cut and approximately 6,700 cubic yards of fill. ANTICIPATED IMPACTS Pursuant to CEQA Guidelines Section 15060(d), DCD will not prepare an initial study prior to commencing work on the EIR. Based on knowledge of other projects in the vicinity of the project site, we anticipate that the project may result in potentially significant impacts in the following CEQA topic areas: • Aesthetics: constructing three-story buildings would alter the aesthetics of a site that is currently occupied by mostly single-story buildings and open space such as sports fields. • Air Quality & Greenhouse Gas Emissions: construction activities and on-going residential-related activities would cause a temporary/permanent increase in emissions of criteria pollutants and greenhouse gases. • Biological Resources: construction activities may result in impacts to a variety of protected plant and animal species. Of special concern are potential impacts to bats and avian species, and to oak trees. There are no wetlands onsite. • Cultural Resources: construction activities may disturb previously undiscovered cultural resources. • Geology & Soils: the existing soil conditions need to be analyzed and prepared in order to ensure soil preparation is sufficient for the project. • Hazards & Hazardous Materials: demolition and construction activities may increase the potential for impact due to hazardous materials. • Hydrology & Water Quality: off-site improvements may be needed to increase the capacity of the local drainage system to accommodate this housing development. • Noise: ambient noise levels may increase temporarily during construction and may increase permanently during residential occupation of the constructed site. • Transportation: residential operations may cause impacts to various intersections' level of serve and increase vehicle miles traveled.

Secondly, what is the practical difference between mailing in Public Comments and virtually attending the Scoping Meeting? I don’t really understand why there are two separate things if they both relate to the EIR. Lastly, what are next steps after the scoping meeting and public comments? When exactly will neighboring property owners be able to directly address the design of the development and not just the potential environmental impacts? I look forward to hearing back from you.

In almost all existing instances along Oak Road, there are buffers at property lines to prevent negative effects of having multistory residential developments in close proximity to one another during construction and afterward. In this instance, SummerHill is ignoring these examples to the extreme detriment of existing property owners at Oak Treat Court. We are asking for a much larger separation or setback between 3-story buildings on neighboring parcels to address serious concerns regarding loss of privacy; access to sun, air and views; casting of shadows, and to mitigate noise during construction.

From:Laura Bramble To:Jennifer Cruz Subject:Letter in protest of Oak Road Townhomes Condo Dev Date:Monday, May 3, 2021 5:47:22 PM Attachments:May 3.docx Please read the attached letter. My name is Laura Bramble and I live in Building 2723 at Oak Road Villas, the property that directly abuts 2740 Jones Road. If this construction commences, I will be in the direct "line of fire" of the construction. The value of my home will be decreased because I will lose the view that makes my home so lovely. I will lose my peace of mind and quiet, which is vital to my health and happiness; I am disabled and quiet is important to my well-being. I work from home a great deal; I will not be able to do that with all the construction noise going on. Please know that my house-bound 83 year old neighbor downstairs will also be directly impacted. She doesn't have internet or a computer so she can't reach out to you like I can. But she's equally impacted and equally unhappy. This unnecessary and destructive construction will only negatively impact a community that is already packed to the gills with condo's, apartments, townhomes, cars, and bad wifi service. And my questions are these: What remunerations will you pay me and my affected neighbors for losing our peace of mind while you are building? What will you pay me for the devaluation of my home when you take away my view? What will you pay all of us who might like to sell but can't because of the construction hell you are attempting to put us through? And WHY do you have to build condo's? What about a park, a community center, a senior center, a day care, a youth center, a YMCA, a church, a day care or leave it as a school? Why on earth do we need somewhere in the neighborhood of 500 more expensive condo's that nobody can afford to buy in the most impacted part of town? Please read my letter and know that you have a fight on your hands. You can't have my peace and quiet, and you can't devalue you my home. You can buy me out and help me move, but you can't just take it away. Very truly yours, Laura Bramble May 3, 2021 County File #CDRZ21-03258, CDSD21-09559, CDDP21-03001 ATTN Ms. Jennifer Cruz I write in response to the Notice of Preparation I received as a resident of Oak Road Villas and the owner of unit 2723-F, which directly abuts the property at 2740 Jones Road. I AM DIRECTLY AND ENERGETICALLY IN OPPOSITION TO THE PLANNED DEVELOPMENT “OAK ROAD TOWNHOUSE CONDOMINIUMS” for the following reasons: 1) This area between Ygnacio Valley Road and Treat Blvd is already highly congested with apartments, townhomes, and condominiums. Parking is horrible, wifi bandwidth is sub-par, traffic congestion is bad especially during heavy commute hours, and the Pleasant Hill BART station is overrun with commuters who both walk and drive to the station. We do not need more people living here. 2) The proposed demolition of trees, buildings, the impact to existing biological resources (including bats, squirrels, birds, soils, and other wildlife) is unacceptable. I DEMAND an environmental impact report be done in its entirety, so that the impact on animals, trees, air, traffic, noise, and all other environs be fully studied. 3) What are you going to do to accommodate the people who live and work from home, and the seniors who live at home and are home-bound, the people who are sick and need quiet, and the people who are at home taking care of elderly parents or young children? What are you going to do about me? I LIVE HERE and work from home as a teacher; I am disabled; I need my quiet; what do you want me to do while you all are banging away making noise disrupting my work and my health? 4) What are you going to do about devaluing the Oak Road Villas Condo complex? We have a large number of renters who can move out. The owners of the rented units will NOT be able to rent those units at all while there is construction going on. That’s a loss of income for those homeowners. The people who live here who might want or need to sell won’t be able to while there’s construction going on. And while you are banging away, you’re ruining the value of our homes by destroying the views that made Building 2723 so special and desirable. You are devaluing existing homes with this construction. 5) The existing Palmer School site can be turned into a day care, a partial park site, it can be re-sold as a school site and upgraded, turned in to a Senior Center, a youth center – there are many other community sites that are NEEDED in this area. We do not need more housing; we need community buildings where people can go. 6) If you do construction, you’re going to make a mess of an already messy intersection! Treat Blvd is a mess during commute hours; now you’re going to make it a mess all day long with trucks of every kind coming and going, blocking the street, impacting residents, making noise, polluting the air with exhaust, and during the summer too when spare-the-air days are at their highest!?! This is inexcusable and irresponsible of Summerhill; they shouldn’t be allowed to pollute our neighborhood just because they can spend big bucks developing land that doesn’t need to be developed. 7) It was congested with traffic when it was Palmer School and there were maybe 400 cars coming and going. Now you want to have more than 500 cars living there permanently, coming and going? 8) If you go ahead and build, what are the remunerations for people who are stuck at home and have to listen to this all day? You will cost a LOT of people their peace and quiet and the comfort of their homes. 9) If you go ahead and build, what will you pay us for the devaluation of our homes, when the views that add value to our homes are lost, in favor of your buildings blocking our vistas? Walnut Creek, even this unincorporated area, does not have the ability to sustain this kind of growth. We already are not a part of the Walnut Creek Police Department. We don’t have enough Sheriff’s deputies to cover our own part of town. BART will be negatively impacted with an increase in ridership, or, traffic will be negatively impacted with more people driving to work and getting on the freeway at a highly densely packed commuter zone. Wifi is bad enough in this “condo row” part of town; now you’re going to have 500 more homes vying for signals? What about the impact on parks, with a potential increase in dog owners who don’t pick up poop? This is a bad idea for a perfect piece of land. Make it a senior center, a youth center, a homeless center, a park, a community center, a day care, keep it as a school, let the city have it to turn into arts and crafts center, make it a church— BUT YOU DO NOT HAVE MY VOTE OR MY PERMISSION TO BUILD ON THIS LAND. Most energetically yours, Laura Bramble 2723-F Oak Road Walnut Creek, CA 94597 Laurabramble10@gmail.com 925 286 0753 From:Laura Bramble To:Jennifer Cruz Subject:Letter Date:Tuesday, May 4, 2021 5:09:26 PM Attachments:May 3.docx Attached... I don't think I sent it the first time. My comments and complaints stand. An unnecessary condo or townhouse development at 2740 Jones Road adds no value to Walnut Creek, and devalues existing homes, contributes to traffic congestion, destroys habitats and trees by your own admission, and your parking study is inconclusive at best because parking in this entire area is grossly under-counted-- there are NOT enough parking spaces for the existing residents and tenants, and now you want to add more homes? It's a nightmare! My question continues to go unanswered: If you continue to go ahead with this bad idea, how are you going to compensate me for the loss of the value to my own home? You're building a 45 foot tall dwelling that will obliterate my views, create noise and other environmental pollution, you've now made it impossible for me to move without having to declare this monstrosity, and IF I can move once it's built, instead of selling a view and a quiet corner unit, I get to sell a "view of condo wall"--- so how are you going to make this right by me? I'M WAITING FOR YOUR ANSWER !!! And so is my 83 year old home bound neighbor downstairs. What are we supposed to do now? I'm disabled, she's 83-- we have minimal income, and now this ridiculous condo nightmare is going to suck the last bit of pleasure out of the quiet corner we have to live in. What are you going to do to compensate us for the noise, destruction of our quiet home, and the loss of property value? Answer expected. THank you.

We are committed to ensuring that impacts to the State’s multimodal transportation system and to our natural environment are identified and mitigated to support a safe, sustainable, integrated and efficient transportation system. The following comments are based on our review of the April 2021 NOP. Project Understanding The project proposes a rezoning of the project site to a Planned Unit District (P- 1), subdivision of the project site into 19 residential lots, and a development plan to allow building condominiums on the site. Travel Demand Analysis With the enactment of Senate Bill (SB) 743, Caltrans is focused on maximizing efficient development patterns, innovative travel demand reduction strategies, and multimodal improvements. For more information on how Caltrans assesses Transportation Impact Studies, please review Caltrans’ Transportation Impact Study Guide . If the project meets the screening criteria established in the City’s adopted Vehicle Miles Trav eled (VMT) policy to be presumed to have a less-than- significant VMT impact and exempt from detailed VMT analysis, please provide justification to support the exempt status in line with the City’s VMT policy. Jennifer Cruz, Principal May 25, 2021 Page 2 “Provide a safe, sustainable, integrated and efficient transportation system to enhance California’s economy and livability” Projects that do not meet the screening criter ia should include a detailed VMT analysis in the Draft Environmental Impact Report (DEIR), which should include the following: ● VMT analysis pursuant to the City’s guidelines. Projects that result in automobile VMT per capita above the threshold of significance for existing (i.e. baseline) city-wide or regional values for similar land use types may indicate a significant impact. If necessary, mitigation for increasing VMT should be identified. Mitigation should support the use of transit and active transportation modes. Potential mitigation measures that include the requirements of other agencies such as Caltrans are fully enforceable through permit conditions, agreements, or other legally-binding instruments under the control of the City. ● A schematic illustration of walking, biking and auto conditions at the project site and study area roadways. Potential safety issues for all road users should be identified and fully mitigated. ● The project’s primary and secondary effects on pedestrians, bicycles, travelers with disabilities and transit performance should be evaluated, including countermeasures and trade -offs resulting from mitigating VMT increases. Access to pedestrians, bicycles, and transit facilities must be maintained. ● Clarification of the intensity of events/receptions to be held at the location and how the associated travel demand and VMT will be mitigated. Mitigation Strategies Location efficiency factors, including community design and regional accessibility, influence a project’s impact on the environment. Using Caltrans’ Smart Mobility 2010: A Call to Action for the New Decade , the proposed project site is identified as a Close-In Compact Community where community design is strong and regional accessibility is fair. Given the place, type and size of the project, the DEIR should include a robust Transportation Demand Management (TDM) Program to reduce VMT and greenhouse gas emissions from future development in this area. The measures listed below have been quantified by California Air Pollution Control Officers Association (CAPCOA) and shown to have different efficiencies reducing regional VMT ● VMT Banking and/or Exchange program; ● Addition/ Increase in number of affordable housing units in project; ● Orientation of project towards non-auto corridor; Jennifer Cruz, Principal May 25, 2021 Page 3 “Provide a safe, sustainable, integrated and efficient transportation system to enhance California’s economy and livability” ● Location of the project near bicycle network(s); ● Incorporation of bicycle lanes in street design; ● Pedestrian network improvements; ● Traffic calming measures; ● Implementation of a neighborhood electric vehicle (EV) network, including designated parking spaces for electric vehicles (EVs); ● Limiting parking supply; ● Unbundled parking from property costs; ● Market price public parking; ● Ridesharing programs, Commute Trip Reduction programs, bike sharing programs; ● Transit and trip planning resour ces such as a commute information kiosk; ● Real-time transit information system; and ● Transit access supporting infrastructure (including bus shelter improvements and sidewalk/ crosswalk safety facilities). Using a combination of strategies appropriate to the project and the site can reduce VMT, along with related impacts on the environment and State facilities. TDM programs should be documented with annual monitoring reports by a TDM coordinator to demonstrate effectiveness. If the project does not achieve the VMT reduction goals, the reports should also include next steps to take in order to achieve those targets. Please reach out to Caltrans for further information about TDM measures and a toolbox for implementing these measures in land use projects.

Transportation Impact Fees Please identify project-generated travel demand and estimate the costs of transit and active transportation improvements necessitated by the proposed project; viable funding sources such as development and/or transportation impact fees should also be identified. We encourage a sufficient allocation of fair share contributions toward multi-modal and regional transit improvements to fully mitigate cumulative impacts to regional transportation. We also strongly support measures to increase sustainable mode shares, thereby reducing VMT. Lead Agency As the Lead Agency, the County of Contra Costa is responsible for all project mitigation, including any needed improvements to the State Transportation Jennifer Cruz, Principal May 25, 2021 Page 4 “Provide a safe, sustainable, integrated and efficient transportation system to enhance California’s economy and livability” Network (STN). The project’s fair share contribution, financing, scheduling, implementation responsibilities and lead agency monitoring should be fully discussed for all proposed mitigation measures. Equitable Access If any Caltrans facilities are impacted by the project, those facilities must meet American Disabilities Act (ADA) Standards after project completion. As well, the project must maintain bicycle and pedestrian access during construction. These access considerations support Caltrans’ equity mission to provide a safe, sustainable, and equitable transportation network for all users. Encroachment Permit Please be advised that any permanent work or temporary traffic control that encroaches onto the State Right of Way (ROW) requires a Caltrans-issued encroachment permit. As part of the encroachment permit submittal process, you may be asked by the Office of Encroachment Permits to submit a completed encroachment permit application package, digital set of plans clearly delineating the State ROW, digital copy of signed, dated and stamped (include stamp expiration date) traffic contr ol plans, this comment letter, your response to the comment letter, and where applicable, the following items: new or amended Maintenance Agreement (MA), approved Design Standard Decision Document (DSDD), approved encroachment exception request, and/or air space lease agreement. Your application package may be emailed to D4Permits@dot.ca.gov .

Sincerely, MARK LEONG District Branch Chief Local Development - Intergovernmental Review c: State Clearinghouse From:Karen Chen To:DCD PlanningHearing Cc:Karen Chen Subject:Summerhill Home Development on Oak Road - County Files # CDRZ21-03258, CDSD21-09559, CDDP21-03001: Date:Monday, May 17, 2021 3:19:38 PM Attachments:image001.png Dear Contra Costa County Zoning Administrator, Hope all is well. I am writing this letter in regards to the county letter that was sent on Apr 28, 2021 informing the neighborhood about the new home development proposed by Summerhill Homes/Sam Mendes. I am a resident of Oak Treat Court, which is on the north side of the proposed future development. Upon reviewing the letter as well as the actual site plan provided by county, I would like to submit some comments as below before the public hearing: Aesthetics/Pollution/Safe to surrounding area Concerns: a. According to the proposal, the land is being proposed to be rezone to code "P-1", in which code 84-66.1402 - Design objectives., it has mentioned that i. "Building bulk, height, land coverage, visual appearance from adjacent land, and design compatibility with existing adjoining development and land which will remain, shall be considered and controlled"; ii. A development's design should successfully integrate individual buildings and building groups with the surrounding development, other physical features in the area, and existing development which will remain; iii. The design of structures should provide for harmonious composition of mass, scale, color, and textures, with special emphasis on the transition from one building type to another, termination of groups of structures, relationships to streets, exploitation of views, and integration of spaces and building forms with the topography of the site and the urban or suburban character of the area. iv. Provisions are to be made for an efficient, direct and convenient system of pedestrian circulation, together with landscaping and appropriate treatment of any public areas or lobbies. v. Off-street parking and loading areas should be integrated into the overall vehicular circulation system. By reviewing the site plan, I have found below concerns conflicting with the P-1 code. i. The height of the development is proposed to be above 42 feet height, with the developer offering a 4th floor "roof deck" option on all structures facing Oak Road. This will make these buildings significantly taller than our community and other neighborhoods, which does not align with Code 84-66.1402-i. I suggest that the height of the building to be controlled and aligned with the neighborhood to be standard 3-story buildings. The county and developer should eliminate the optional 4th floor "roof deck" on the Oak Road side of the development with potential environmental concerns such as 1. Activities on roof top can easily cause pollution/potential fire to nextdoor neighbors with such small setback (currently planning 15 ~ 16 ft setback in between new development and Oak Treat Ct) - imagine someone is BBQ on the roof deck, a fire could be caused just by a small spark or smoke flying from the roof top to Oak Treat Ct's roof. 2. Safety concern - people can easily reach Oak Treat Ct community from their roof deck. 3. Noise concern - with more than 30 roof deck being created, it will bring more noises to the area and could highly affect the neighbors with such small setback on each side of the new development with their next-door communities ii. The Setback – current planned setback in between the south side of Oak Treat Court and Summerhill Development is 15ft ~ 16ft. And in such a short distance, there’s also planned parking space. This is a big concern for the residents of Oak Treat Court as below and the county should urge the developer to update their site plan to create/switch the new plan’s open space, driveway or landscaping in between their plan and the southside of Oak Treat Court to create at least 60 feet setback in between the new plan’s actual building structures and Oak Treat Court 1. Foundation: The land and soil has been years designated for hundred-year-old plants, school, single story residential and open space. We are worried the foundation of surrounding area including our Oak Treat Court community’s foundation would be highly affected or damaged due to the 125 units of 3 to 4-story buildings’ weight on such land/soil 2. Noise: During and after construction, if the structure is being built within such a small setback, the noise would be highly affecting the daily life of Oak Treat Court residents and other neighborhood 3. Pollution: During and after construction, it will cause severe pollution to Oak Treat Court’s structure with such a small setback including air pollution, light pollution and noises, which could be irrevocable 4. Safety concern: During the construction, it is very easy to cause damage to Oak Treat Court’s structure with such a small setback such as the noise cause windows the break, or tools being threw and dropped to our buildings 5. Privacy/Safety concerns: With such setback, the potential buyer of the new development’s privacy & safety, as well as the Oak Treat Court residents’ privacy/safety are not protected. The amounts of windows and decks facing right nextdoor should be limited just like the other communities on the Oak Road. The existing structures on Oak Road have strived to protect the privacy/safety of both parties and this is the basic respect to home owners. 6. Within the new site plan, it is doable for the Summerhill Developer to shift their Oak Road entrance and landscaping to be right next to the southside of Oak Treat Court and create the requested open space and setback of 60 feet in between Oak Treat Court structures and the new development. (see below drawing) Appreciate your consideration and the residents on Oak Treat Court will actively seeking to attend public hearing, writing proposals and hoping to coordinate with county/developer for the upcoming construction which could really benefit all parties. Best regards, Karen Chen Resident of Oak Treat Court From:sindy kirkland To:DCD PlanningHearing Subject:Serious concerns regarding proposed “Oak Road Townhouses condominium” Project Date:Monday, May 17, 2021 8:16:32 AM Dear County DCD, I am a home owner in current Oak Treat Court which would be the immediate neighbor for the proposed project mentioned above in the email subject line. Besides echoing County’s entire anticipated impacts that definitely will be realized if the Project would be allowed, I want to strongly voice my concerns the project would bring to our 16 units small Court and its profound environmental negative impacts to the area. I read the over 100 pages Summer Hill builder plan for their Oak Road Townhouse Condominium. Simply put, it is ugly, over crowded and poorly designed. The style would not even close to be comparable to our Court which has been here since 2004. Since it would be on the main road, it would bring down the property values and have a negative impact to the city of Walnut Creek as a whole. And because the land parcel immediately adjacent to the Court has been used as a farmland for decades, even over a century, it would seriously alter the ecosystem by building such a large project as high as 45 feet and introducing so many new residents of over 100 units. And it would have the adverse implications to our Court, such as Court foundation, quality of life, etc. Yes, we recognize the need of some kind of appropriate project next door. I am urging you, our County, to keep the current zoning for the above said parcel and develop it accordingly. Thank you very much for your attention on it! This matter is related so closely to our daily life.

Such tall buildings so close to existing property owners would block access to direct sunlight; blue sky; would cast shadows; limit breezes; destroy views and invade privacy. Provide much greater setback and landscape buffer to act in good faith towards existing property owners. 17 Jennifer Cruz Planner, Department of Conservation & Development, Contra Cost County Re: 2740 Jones Road Redevelopment of the Palmer School site Jennifer: Thank you for the opportunity to comment on the Arborist Plan for the development at 2740 Jones Road known as the Oak Road Townhouse Condominiums. First, we would like to repeat that we are delighted that this project is for-sale units, a very refreshing change from the previous large-scale projects in the area. However, as you are no doubt aware, we have major objections to what amounts to effectively the clear cutting of 75 of the 81 trees on the site. Of particular concern to us, naturally, is the planned destruction of the seven Heritage Valley Oaks with diameters ranging up to 73 inches. We find it disingenuous that a development capturing the Oak name and depicting full grown examples of Heritage Oaks in its plot description will only preserve one Oak which is off-site and another with a 13-inch diameter which will be relocated. We note that the City of Walnut Creek, when faced with an ultimatum from the developer of the Tiffany site to remove a Heritage Oak, held fast and insisted that the developer instead build around the tree. In fact, the final plan for the site highlighted this beautiful tree. We would argue that, in like manner, the County resist the developer’s initial plan and, instead, insist that the developer make a conscious effort to incorporate these irreplaceable trees into its final plan. Should economics dictate the necessity of maintaining the planned 125 units on this six-acre site, then the developer should consider adding a fourth floor to some of the buildings. We furthermore question the necessity of destroying 24 healthy mature Coast Redwoods on the southern border of the property only to replace them at a later date. Can they not be preserved given the setback requirements for the buildings? They provide a wonderful green break from the adjoining properties. Thank you again for keeping us informed of the developments of this project, and we look forward to following the County’s actions in response to our objections.

None of the residents who might have an opinion or want to sit in on the meeting will have power, including Internet, to join the meeting and participate effectively.

Thanx, Larry McEwen, Secretary Walden District Improvement Association (925) 9329-3216 May 21, 2021 Zoning Administrator’s meeting 3:30 p.m. Scoping Session: Item 2a. Becky: We the undersigned Oak Road Station homeowners at 2700 -2728 Oak Road, located across the street of the proposed Oak Rd. Townhouse condominiums the numbers that Margaret just read, vigorously oppose their application for rezoning and the current development plan. The project that’s presented will have a negative and permanent negative impact on our community for the following reasons: 1. Ascetics: Palmer School consists of one-story building with multipole open space, such as sports field, parking lot and numerous meeting areas. Their plan calls for nineteen 3 story buildings, and a crowded cluttered concrete jungle. The artistic style of the site would be destroyed. I have eight points. 2. Air quality and greenhouses gas emissions, construction activities and eventual occupation of site with permanently effect our community’s air quality and constant release of critical pollutant and greenhouse gases. 3. Natural and biological: the plan calls for removal of 74 long, established trees with location of one oak tree, and I know which one that is. This proposal alone should raise enough red flags to halt the approval of the zoning plan, due to environmental concerns. Also at risk are plant and animal species and their natural habitat. 4. Hazardous materials: Palmer school was built over 80 years ago when asbestos was the preferred construction material. Our community could now possibly be spared the permanent impact of these airborne demolition hazard. 5. Noise: Oak Grove station resident will be negatively, permanently affected by unacceptable noise pollution due to demolition destruction and occupation of the housing development. Any of us can hear the day to day noises at Palmer school, including playground noises and school bells. 6. Traffic: their plan as presented will cause a negative and permanent impact on area traffic patterns already cluttered with vehicles. Perhaps they might consider keeping the current entry on Jones Road only. 7. Parking: Currently, finding available parking is extremely difficult. Their plan would further permanently affect accessible parking. How many residential, we already determined that. 125 plus 10, that is 278 parking places is not enough. Street parking would be negative and permanently affected. 8. Neighborhood: Our walking trails are regularly ingested with walkers and bikers. Also, our small neighborhoods parks are over crowded already and this new concrete jungle with condos cramped together would further negatively effect these areas. I’m going to submit this with these signatures of our home owners. We implore the Contra Costa City department of Conservation and development seriously consider the negative and permanent impacts of the Oak Grove station neighborhood but to the whole surrounding community. And on a final note, Mr. Sam if your listening, I’m part of your Palmer family, I know you grew up on that site. I know which building was your house on that site. I know you went to school there. Became the principal. You grew up with those trees. You told me that your grandparents named Oak Grove because it was just an orchard back then. You grew up with those 74 trees Mr. Sam. So thank you for hearing me everybody. And somebody needs to give your person, Jennifer a raise. She is right on the reply on everything. So thank you again. Phil Abelara: Thanks for having us here today. I also received the letter from Jennifer Cruz. I live at 15 Oak Tree Ct. We are a also a condominium association just north of the proposed project. While we do have some very serious concerns with the project going up, we are mostly concerned with the manner of which the development has been proposed. I only have 3 minutes, but we also are writing a letter, putting down our concerns. But essentially what we wanted to do is have a discussion to respect ot the way the buildings are designed. Our biggest concern now is with the proximity and the set backs and the size and scope of some of these buildings. We understand that Walnut Creek and the bay area needs housing, we live in a more dense area up here in northern Walnut Creek unincorporated. So me personally, I’m not going against the project whole heartedly, but I am against the manner of which its being proposed. And the manner of which the set backs and concerns that we have. With respect to the anticipated impacts, I echo Becky’s comments with respect to aesthetics air quality, etc., you know the aesthetics are open to debate, however what is not open for debate is the approximately of the buildings, the are too close and the set backs need to be changed. With respect to air quality and green house gas emissions, we are all also concerned about air quality and air pollution, odor and smells. With respect to geology and soils. We are concerned with potential substance foundation exterior cracks that may affect our property, as well as the surrounding properties around the proposed project. Also, what is not on the impact list is light. Lighting is very, very key. And what hasn’t been mentioned is the lack of some of our residents are going to have if these buildings are built 13 feet away from our existing buildings as well. Not only that, but night light or light pollution from the new buildings, how is that going to be addressed. In closing, I have a couple of seconds here. As we all know owners in a right to privacy and quiet enjoyment of their premises and anything unreasonably interferes with that is considered a nuisance and trespass. What we’d like to do is be able to have a discussion with the County, as well as the developer, to come up with a proposed plan with respect with the setbacks, perhaps the heights and the size of some of these buildings. Thank you very much. Karen Chen: I am also a resident of the Oak Tree Ct. besides Phil. He’s a great Board of Director of the community, he expressed most of our points. I just want to emphasize on the set back and the height limit on the propose plan that *** which really concerns us because there pollution and concern with the 15 set back even under the proposed P-1, there are required to be consisted with the other existing structures and the road and also created a more harmony design of the building high and length coverage, which I just sent letter right before this meeting to your email as well. I think that really important according to the P-1 collaborating from the County code. So the height what really concerns me is optional roof that they are offering the potential buyers, which is a 3 ½ floor building on the Oak Road side, which the roof that is open space to their potential buyers but also the is the risk to our existing structure because its so close to our building, for example people are doing some bbq on their roof deck and a fire spark and can cause some fire in the surrounding neighborhood or smoke or noises, which is irrevocable and existing for years. Because you can’t control who is moving and who is going to do what activities on those roof decks. Which those are optional on their proposed *****. So I think the County should urge them to actually eliminate those optional roof deck that’s building the higher building on the Oak Road side and right next to us. Also, for years those soil have been designed for the 100 year old **** and single story building or open space. So we are worried about those foundation, if the set back is only 15 feet. There are still close to us, removing those 100 year old trees also those 125 units have such a big weight for those foundations and other foundations of other neighborhoods and that is a big concerns. Also, during construction, it’s so close to us and what if someone drop a tool or they can the construction workers can easy access our community so we are very concerned about safety and pollution as well as is pretty much very possible to cause damage to our structure. Also with small set back, the privacy is for both side because I believe those facing us have windows facing them too so we are basically seeing each other or living tougher to be honest. Just looking at each others daily life. We respect the land needs to be built since the school is gone right now. So the new development needs to be there we would appreciate if they can respect the surrounding area and respect the code the P-1 code proposed to rezone to P-1 then they have to consider the compatibility with the existing, adjoined development and that’s existing and will remain in the future. We will keep sending some proposal as in the home association will write and other letters as well. But we appreciate that and the most important is the set back, the 15 or 16 set back is too close and could potently cost damages to our foundation, pollution, noises, safety concerns and the site plan it is very possible and doable for them if they shift the entry of Oak Grove and their landscaping to our side. Then that would create an open space in between us and their new development. Just because even in-between their own building they have open space. Thank you. Craig McIntire Mann- I too am an owner and neighbor at Oak Tree Court, along with Phil and Karen. I echo everything they shared and also echo some of the things Becky shared. We do need housing here in Walnut Creek, although I’d like to emphasize we really need is not million dollar homes, but we need affordable housing. The people that are threat of being homeless. So, I wanted to just get that in there but I want to share, as Phil shared that not opposed to the development going in there, but would like to dialogue with everyone at play. I think I echo those statements by Karen & Phil. One of my issues is removing 100+ year old Oak trees, it’s a historical landmark and I would think that they Sommerhill very easily alter their plans to some degree to allow for that Oak Tree to stay and what a selling point that would be for future residents to have this huge Oak tree focal point. So it’s kind of a win-win. And as Karen said, so that will hopefully by changing their plans a bit will help the close proximity to my neighborhood that are immediately butt up to the property. So I think that’s basically some much has already been said to put in that more nature specific note. Thanks so much. Matthew Banford- I also live at the Oak Tree complex. I would like to echo with Phil and the others, I think everybody is making great points. I also sent in some kind of a document, documenting kind of set backs and separation all along Oak Road. I don’t know if you can confirm if that was received for public comment? But, essentially I walk down the road, Oak Road and I kind of just witnessed separations between to the two building and just to the point that again especially what Karen was saying, these proposed set back are very close to our homes in particular and one thing I really wanted to point out and I don’t know perhaps if the developer or architects understand is that north property line along this proposed development really that is our front yard. Our doors or on that side. Those are the windows we look out of everyday, that is where we get our sunlight. So the prospect of having this 40 foot tall buildings directly next to my front door casting shadows blocking my views is just really, really disheartening and it’s a fairly traumatic to be honest. So again, I sent in a document sort of showing pictures and aerial view of what we see as sort of an existing buffer as examples going down Oak Road and me in particular I’m a little perplexed why the developer wouldn’t have considered these examples and possibly using a driveway as sort of a natural buffer between different parcels. Again, I just wanted to point out in particular that property line is our front yard. So it’s very disheartening that they decided to put these 40 foot almost 4 story buildings 15 feet away from my front door. So again we are not opposed to development. I expected that, the fact that its so close is very disheartening, Thank you for my time. Salman S. – I’m another neighbor in Walnut Creek. We have concerns about construction noise and debris. We have an infant son. We know there are other infants on Oak Tree Ct as well, who those families are going to be greatly affected by the noise, debris what have you from constructions. So, I wanted to make sure all the concerns were also heard. Paul: I am also an owner at Oak Tree Court. In addition to echoing what everybody else has said, I would like to voice my concerns to the set back and preserve one of the oak trees that faces, to be honest, it faces my unit and my living room window. It’s much nicer to look out on a oak tree than a 45 foot wall. If there is a way in preserving the oak tree that would be very beneficial.

Reyff 429 E. Cotati Avenue Cotati, CA 94931 (707) 794-0400 I&R Job #: 20-187 1 Introduction The purpose of this report is to address air quality and greenhouse gas (GHG) emissions impacts associated with the proposed SummerHill Homes Oak Road Townhouse Condominium Development (“Project”) involving approximately 5.7 acres at Jones Road and Oak Road in Contra Costa County, near Walnut Creek, California. The air quality impacts associated with the project would be from the demolition of the existing uses (former Palmer School site), construction of new buildings and infrastructure, and operation of the new multifamily residential development. Air pollutant emissions associated with the construction and operation of the project were predicted using appropriate computer models. In addition, the potential construction community risk impact to nearby sensitive receptors and the impact of existing toxic air contaminant (TAC) sources affecting the new residential units were evaluated. This analysis addresses those issues following the guidance provided by the Bay Area Air Quality Management District (BAAQMD).1 Project Description The property being acquired for the development was the recent site of the Palmer School, which closed permanently in 2020. This school has a more than 80-year history of operating at the site, adjacent to I-680 and BART. Baseline conditions for the project site include the following: • Palmer School operated continuously in the sit from 1939 to June 2020, when COVID restrictions made it impossible to operate; • Eighteen (18) buildings plus other portable structures exist on the site, totaling about 50,000 sf of lot coverage, along with on-site parking and typical school facilities; • During the last 10 years of operation student count between 370 and 400 students along with 40-52 staff members; • Daily school hours of operation were 7:00 AM to 6:00 PM Monday to Friday; • Summer Program of 10 weeks with 100 to 160 students, 7:00 AM to 6:00 PM Monday to Friday, plus 25 staff members; and • Night time meetings for parents along with scouting and other activities. The project proposes to demolish all existing pavement and structures, re-grade the site, and construct several townhouse-style condominium buildings. Specifically, the project would construct: • 125 dwelling units in 19 three-story buildings ranging from approximately 1,250 to 2,250 square feet (sf) with attached two-car garages, • Approximately 34 surface parking spaces and roadways, totaling 73,930 sf of onsite asphalt surfaces. • Approximately 58,360 sf of common open spaces and 33,7670 sf of private open spaces. Setting The project is in unincorporated Contra Costa County, which is in the San Francisco Bay Area Air Basin. Ambient air quality standards have been established at both the State and federal level. The 1 Bay Area Air Quality Management District, CEQA Air Quality Guidelines, May 2017. 2 Bay Area meets all ambient air quality standards except for ground-level ozone, respirable particulate matter (PM10), and fine particulate matter (PM2.5). Air Pollutants of Concern High ozone levels are caused by the cumulative emissions of reactive organic gases (ROG) and nitrogen oxides (NOX). These precursor pollutants react under certain meteorological conditions to form high ozone levels. Controlling the emissions of these precursor pollutants is the focus of the Bay Area’s attempts to reduce ozone levels. The highest ozone levels in the Bay Area occur in the eastern and southern inland valleys that are downwind of air pollutant sources. High ozone levels aggravate respiratory and cardiovascular diseases, reduce lung function, and increase coughing and chest discomfort. Particulate matter is another problematic air pollutant of the Bay Area. Particulate matter is assessed and measured in terms of respirable particulate matter or particles that have a diameter of 10 micrometers or less (PM10) and fine particulate matter where particles have a diameter of 2.5 micrometers or less (PM2.5). Elevated concentrations of PM10 and PM2.5 are the result of both region-wide (or cumulative) emissions and localized emissions. High particulate matter levels aggravate respiratory and cardiovascular diseases, reduce lung function, increase mortality (e.g., lung cancer), and result in reduced lung function growth in children. Toxic Air Contaminants TACs are a broad class of compounds known to cause morbidity or mortality (usually because they cause cancer) and include, but are not limited to, the criteria air pollutants. TACs are found in ambient air, especially in urban areas, and are caused by industry, agriculture, fuel combustion, and commercial operations (e.g., dry cleaners). TACs are typically found in low concentrations, even near their source (e.g., diesel particulate matter [DPM] near a freeway). Because chronic exposure can result in adverse health effects, TACs are regulated at the regional, State, and federal level. Diesel exhaust is the predominant TAC in urban air and is estimated to represent about three- quarters of the cancer risk from TACs (based on the Bay Area average). According to the California Air Resources Board (CARB), diesel exhaust is a complex mixture of gases, vapors, and fine particles. This complexity makes the evaluation of health effects of diesel exhaust a complicated scientific issue. Some of the chemicals in diesel exhaust, such as benzene and formaldehyde, have been previously identified as TACs by the CARB, and are listed as carcinogens either under the State's Proposition 65 or under the Federal Hazardous Air Pollutants programs. The most recent Office of Environmental Health Hazard Assessment (OEHHA) risk assessment guidelines were published in February of 2015.2 See Attachment 1 for a detailed description of the community risk modeling methodology used in this assessment. 2 OEHHA, 2015. Air Toxics Hot Spots Program Risk Assessment Guidelines, The Air Toxics Hot Spots Program Guidance Manual for Preparation of Health Risk Assessments. Office of Environmental Health Hazard Assessment. February. 3 Sensitive Receptors There are groups of people more affected by air pollution than others. CARB has identified the following persons who are most likely to be affected by air pollution: children under 16, the elderly over 65, athletes, and people with cardiovascular and chronic respiratory diseases. These groups are classified as sensitive receptors. Locations that may contain a high concentration of these sensitive population groups include residential areas, hospitals, daycare facilities, elder care facilities, elementary schools, and parks. For cancer risk assessments, children are the most sensitive receptors, since they are more susceptible to cancer causing TACs. Residential locations are assumed to include infants and small children. The closest sensitive receptors to the site are children that may be living in the multifamily homes adjacent to the project site. The John Muir Health/Walnut Creek Medical Center is the next closest sensitive receptor, located approximately 1,580 feet (i.e., one third of a mile) to the northeast of site. Once constructed, the project would introduce new sensitive receptors (i.e., infants and children) to the area. Regulatory Agencies CARB has adopted and implemented several regulations for stationary and mobile sources to reduce emissions of DPM. Several of these regulatory programs affect medium and heavy-duty diesel trucks that represent the bulk of DPM emissions from California highways. These regulations include the solid waste collection vehicle (SWCV) rule, in-use public and utility fleets, and the heavy-duty diesel truck and bus regulations. In 2008, CARB approved a new regulation to reduce emissions of DPM and nitrogen oxides from existing on-road heavy-duty diesel fueled vehicles.3 The regulation requires affected vehicles to meet specific performance requirements between 2014 and 2023, with all affected diesel vehicles required to have 2010 model-year engines or equivalent by 2023. These requirements are phased in over the compliance period and depend on the model year of the vehicle. The BAAQMD is the regional agency tasked with managing air quality in the region. At the State level, the CARB (a part of the California Environmental Protection Agency [EPA]) oversees regional air district activities and regulates air quality at the State level. The BAAQMD has published California Environmental Quality Act (CEQA) Air Quality Guidelines that are used in this assessment to evaluate air quality impacts of projects.4 The detailed community risk modeling methodology used in this assessment is contained in Attachment 1. Contra Costa County General Plan 2005 - 2020 The project is located in an unincorporated portion of Contra Costa County that is almost surrounded by the City of Walnut Creek. The Contra Costa County General Plan applies to this area. The current general plan and amendments for Contra Costa County includes goals, policies, and actions to reduce exposure of the county’s sensitive population to air pollution and toxic air contaminants (TACs). The following goals, policies, and actions are applicable to the proposed project: Applicable Goals 3 Available online: http://www.arb.ca.gov/msprog/onrdiesel/onrdiesel.htm.

The county is in the process of updating its General Plan. The new plan, Envision 2040, will respond to current concerns about sustainability, environmental justice, and affordable housing, while carrying forward enduring County values like balancing growth and conservation. 5 Significance Thresholds In June 2010, BAAQMD adopted thresholds of significance to assist in the review of projects under CEQA and these significance thresholds were contained in the District’s 2011 CEQA Air Quality Guidelines. These thresholds were designed to establish the level at which BAAQMD believed air pollution emissions would cause significant environmental impacts under CEQA. The thresholds were challenged through a series of court challenges and were mostly upheld. BAAQMD updated the CEQA Air Quality Guidelines in 2017 to include the latest significance thresholds that were used in this analysis, as summarized in Table 1. Table 1. Air Quality Significance Thresholds Criteria Air Pollutant Construction Thresholds Operational Thresholds Average Daily Emissions (lbs./day) Average Daily Emissions (lbs./day) Annual Average Emissions (tons/year) ROG 54 54 10 NOx 54 54 10 PM10 82 (Exhaust) 82 15 PM2.5 54 (Exhaust) 54 10 CO Not Applicable 9.0 ppm (8-hour average) or 20.0 ppm (1-hour average) Fugitive Dust Construction Dust Ordinance or other Best Management Practices Not Applicable Health Risks and Hazards Single Sources Within 1,000-foot Zone of Influence Combined Sources (Cumulative from all sources within 1000-foot zone of influence) Excess Cancer Risk >10 per one million >100 per one million Hazard Index >1.0 >10.0 Incremental annual PM2.5 >0.3 µg/m3 >0.8 µg/m3 Greenhouse Gas Emissions Land Use Projects – direct and indirect emissions Compliance with a Qualified GHG Reduction Strategy OR 1,100 metric tons annually or 4.6 metric tons per capita Note: ROG = reactive organic gases, NOx = nitrogen oxides, PM10 = course particulate matter or particulates with an aerodynamic diameter of 10 micrometers (µm) or less, PM2.5 = fine particulate matter or particulates with an aerodynamic diameter of 2.5µm or less. GHG = greenhouse gases. 6 AIR QUALITY IMPACTS AND MITIGATION MEASURES Impact: Conflict with or obstruct implementation of the applicable air quality plan? BAAQMD is the regional agency responsible for overseeing compliance with State and Federal laws, regulations, and programs within the San Francisco Bay Area Air Basin (SFBAAB). BAAQMD, with assistance from the Association of Bay Area Governments (ABAG) and Metropolitan Transportation Commission (MTC), has prepared and implements specific plans to meet the applicable laws, regulations, and programs. The most recent and comprehensive of which is the Bay Area 2017 Clean Air Plan.5 The primary goals of the Clean Air Plan are to attain air quality standards, reduce population exposure and protect public health, and reduce GHG emissions and protect the climate. The BAAQMD has also developed CEQA guidelines to assist lead agencies in evaluating the significance of air quality impacts. In formulating compliance strategies, BAAQMD relies on planned land uses established by local general plans. Land use planning affects vehicle travel, which in turn affects region-wide emissions of air pollutants and GHGs. The 2017 Clean Air Plan, adopted by BAAQMD in April 2017, includes control measures that are intended to reduce air pollutant emissions in the Bay Area either directly or indirectly. Plans must show consistency with the control measures listed within the Clean Air Plan. At the project-level, there are no consistency measures or thresholds. The proposed project would not conflict with the latest Clean Air planning efforts since 1) project would have emissions below the BAAQMD thresholds (see below), 2) the project would be considered urban infill, and 3) the project would be located near transit with regional connections, and 4) the project site has been occupied with similar sensitive land uses. Impact: Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable State or federal ambient air quality standard? The Bay Area is considered a non-attainment area for ground-level O3 and PM2.5 under both the Federal Clean Air Act and the California Clean Air Act. The area is also considered non-attainment for PM10 under the California Clean Air Act, but not the federal act. The area has attained both State and Federal ambient air quality standards for carbon monoxide. As part of an effort to attain and maintain ambient air quality standards for O3, PM2.5 and PM10, the BAAQMD has established thresholds of significance for these air pollutants and their precursors. These thresholds are for O3 precursor pollutants (ROG and NOx), PM10, and PM2.5 and apply to both construction period and operational period impacts. Construction Period Emissions The California Emissions Estimator Model (CalEEMod) Version 2016.3.2 was used to estimate emissions from on-site construction activity, construction vehicle trips, and evaporative emissions. The project land use types and size, and anticipated construction schedule were input to CalEEMod using CalEEMod default values. The CARB EMission FACtors 2021 (EMFAC2021) model was used to predict emissions from construction traffic, which includes worker travel, vendor trucks 5 Bay Area Air Quality Management District (BAAQMD), 2017. Final 2017 Clean Air Plan. 7 and haul trucks.6 The model output from CalEEMod along with construction inputs are included as Attachment 2 and EMFAC2021 vehicle emissions modeling outputs are included in Attachment 3. Land Use Inputs The proposed project land uses were input into CalEEMod as follows: • 125 dwelling units and 292,965 sf entered as “Residential- Condo/Townhouse” on 5.7 acres. • 34 parking spaces in “Parking Lot” estimated at approximately 13,600 sf. • 1.39 acres (60,331 sf) of other asphalt surfaces to represent other paved areas such as roadways,. • 2.12 acres (92,129 sf) entered as “City Park” to represent common and private open spaces that may be maintained through landscaping and watering. Construction Inputs CalEEMod computes annual emissions for construction that are based on the project type, size, and acreage. The model provides emission estimates for both on-site and off-site construction activities. On-site activities are primarily made up of construction equipment emissions, while off- site activity includes worker, hauling, and vendor traffic. The construction build-out scenario, including equipment list and schedule, were based on CalEEMod defaults for a project of this type and size. According to SummerHill Homes, construction would begin in September 2022 and continue through mid-2026. Much of the emissions are likely to occur in the first year when demolition, site preparation and grading activities occur. Since specific construction details are not known, CalEEMod default assumptions were used for construction equipment, equipment quantities, average hours of equipment use per day, and work schedule for each phase. Although construction would occur over a longer period with lower average daily emissions, the CalEEMod default construction schedule of approximately 15 months, or 330 construction workdays was used. This provides an upper bound estimate of construction emissions (i.e., a conservative assessment). In this scenario, all construction is estimated to be complete by November 2023. However, residential build-out would occur into 2026. The first year of operation is not likely until 2026 when emission rates are lower. Construction Truck Traffic Emissions Construction would produce traffic in the form of worker trips and truck traffic. The traffic-related emissions are based on worker and vendor trip estimates produced by CalEEMod and haul trips that were estimated for demolition material to be exported, soil material imported and/or exported to the site, and cement and asphalt truck trips. CalEEMod provides daily estimates of worker and vendor trips for each applicable phase. The total trips for those were computed by multiplying the daily trip rate by the number of days in that phase. Haul trips for demolition were estimated using CalEEMod defaults for trips per square-foot of material demolished. The square feet of material 6 See CARB’s EMFAC2017 Web Database at https://www.arb.ca.gov/emfac/2017/ 8 to be demolished on site was estimated to be 50,000 sf. Likewise, the number of concrete and asphalt total round haul trips were estimated using the information provided by the applicant and an assumed 10 cubic yards (CY) per material delivery for the project. Concrete/asphalt deliveries were converted to total one-way trips by assuming two trips per delivery. The latest version of the CalEEMod model is based on the older version of the CARB EMFAC2014 motor vehicle emission factor model. This model has been superseded by the EMFAC2017 model. However, CalEEMod has not been updated to include EMFAC2017 or the recent EMFAC2021 model. The construction traffic information was combined with EMFAC2021 motor vehicle emissions factors. EMFAC2017 provides aggregate emission rates in grams per mile for each vehicle type. The construction traffic vehicle mix for this study was based on CalEEMod default assumptions, where worker trips are assumed to be comprised of light-duty autos (EMFAC category LDA) and light duty trucks (EMFAC category LDT1and LDT2). Vendor trips are comprised of delivery and large trucks (EMFAC category MHDT and HHDT) and haul trips, including cement trucks, are comprised of large trucks (EMFAC category HHDT). Travel distances are based on CalEEMod default lengths, which are 10.8 miles for worker travel, 7.3 miles for vendor trips and 20 miles for hauling (demolition material export). Each trip was assumed to include an idle time of 5 minutes and emissions associated with vehicle starts were also included. EMFAC2021 emission rates from calendar year 2022 for Contra Costa County were used. Table 2 provides the traffic inputs that were combined with the EMFAC2021 emission factors to compute vehicle emissions. Table 2.

Summary of Computed Construction Period Emissions Annual emissions were predicted using CalEEMod and EMFAC2021. Average daily emissions were computed by dividing the total construction emissions each year by the number of construction days in that year; 87 in 2022 and 234 in 2023 (321 construction workdays total). Table 9 3 shows daily construction emissions of ROG, NOX, PM10 exhaust, and PM2.5 exhaust estimated during construction of the project. As indicated in Table 3, predicted construction period emissions would not exceed the BAAQMD significance thresholds. Table 3.

Construction activities, particularly during site preparation and grading, would temporarily generate fugitive dust in the form of PM10 and PM2.5. Sources of fugitive dust would include disturbed soils at the construction site and trucks carrying uncovered loads of soils. Unless properly controlled, vehicles leaving the site would deposit mud on local streets, which could be an additional source of airborne dust after it dries. The BAAQMD CEQA Air Quality Guidelines consider these impacts to be less-than-significant if best management practices are implemented to reduce these emissions. Mitigation Measure AQ-1 would implement BAAQMD-recommended best management practices to reduce fugitive dust (PM10 and PM2.5). Mitigation Measure AQ-1: Implement BAAQMD-Recommended Basic and Additional Measures to Control Particulate Matter Emissions during Construction. Measures to reduce fugitive dust (i.e., PM2.5) emissions from construction are recommended to ensure that health impacts to nearby sensitive receptors are minimized. During any construction period ground disturbance, the applicant shall ensure that the project contractor implements both basic and additional measures to control dust and exhaust. Implementation of the dust control measures recommended by BAAQMD and listed below would reduce the air quality impacts associated with grading and new construction to a less-than-significant level. The contractor shall implement the following enhanced best management practices: 1. During site preparation and grading, all exposed surfaces shall be watered at a frequency adequate to maintain minimum soil moisture of 12 percent. Moisture content can be verified by lab samples or moisture probe. 2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered. 3. All visible mud or dirt track-out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. 4. All vehicle speeds on unpaved roads shall be limited to 15 mph. 10 5. All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible.

Effectiveness of Mitigation Measure AQ-1 Mitigation Measure AQ-1 represents enhanced mitigation measures that would achieve greater than an 80 percent reduction in on-site fugitive PM2.5 emissions. These measures are consistent with recommendations in the BAAMQD CEQA Guidance for providing “best management practices” to control construction emissions. Operational Period Emissions Operational air emissions from the project would be generated primarily from autos driven by future residents and guests. Evaporative emissions (e.g., ROG) from architectural coatings and maintenance products (classified as consumer products) are typical emissions from residential projects. CalEEMod was used to estimate emissions from operation of the proposed project assuming full build-out. Land Uses The project land uses were input to CalEEMod as described above. 11 Model Year Emissions associated with vehicle travel depend on the year of analysis because emission control technology requirements are phased-in over time. Therefore, the earlier the year analyzed in the model, the higher the emission rates utilized by CalEEMod. The earliest full year of operation would be 2024 if construction begins in September of 2022. Emissions associated with build-out later than 2024 would be lower than those estimated for 2024. Trip Generation Rates CalEEMod allows the user to enter specific vehicle trip generation rates. Therefore, the project- specific daily trip generation rate for Multifamily Housing - Midrise (Institute of Transportation Engineers Land Use Code 221) were provided by the traffic consultant.7 Saturday and Sunday trip rates were assumed to be the weekday rate adjusted by multiplying the ratio of the CalEEMod default rates for Saturday and Sunday trips to the default weekday rate. Default trip lengths and trip types specified by CalEEMod for each input land use were used for the emissions estimates. EMFAC2021 Adjustment As previously described, the vehicle emission factors and fleet mix used in CalEEMod are based on EMFAC2014, which is an older CARB emission model for on-road and off-road mobile sources. Since the release of CalEEMod Version 2016.3.2, a new emission model has been produced by CARB. A new version of EMFAC2021 became available for use in April 2021. It includes the latest understanding of vehicle emissions and data on California’s car and truck fleets and travel activity. Therefore, the CalEEMod vehicle emission factors and fleet mix were updated with the emission rates and fleet mix from EMFAC2021. On-road emission rates for Contra Costa County, calendar year 2024 were used. More details about the updates in emissions calculation methodologies and data are available in the EMFAC2021 Technical Support documents.8 Energy CalEEMod defaults for energy use were used, which include the 2016 Title 24 Building Standards. GHG emissions modeling includes those indirect emissions from electricity consumption. The electricity produced emission rate was modified in CalEEMod. CalEEMod has a default emission factor of 641.3 pounds of CO2 per megawatt of electricity produced, which is based on Pacific Gas and Electric’s (PG&E) 2008 emissions rate. However, PG&E published in 2019 emissions rates for 2010 through 2017, which showed the emission rate for delivered electricity had been reduced to 210 pounds CO2 per megawatt of electricity delivered in the year 2017.9 This intensity factor was used in the model and it was assumed that all powered was supplied by PG&E. The project is designed be all-electric construction in the new homes with no natural gas provided. Each home will have roof-top solar panels. The number and orientation of the panels will vary 7 Trip rates provided via email by the project’s traffic consultant (Hexagon Transportation Consultants, Inc.), January 5, 2021. 8 See CARB 2021: https://content.govdelivery.com/accounts/CARB/bulletins/2d48287 9 PG&E, 2019.

At a minimum, the solar panels would off-set the increased electricity demand for appliances that may have been traditionally Other Inputs Default model assumptions for emissions associated with solid waste generation and water/wastewater use were applied to the project. Water/wastewater use was changed to 100% aerobic conditions to represent wastewater treatment plant conditions. All hearths were assumed to be natural gas powered. Existing Uses A CalEEMod model run was developed to estimate emissions from the existing land uses. The project site is the former Palmer School and contains structures and pavement used by the school, as follows: • 30,930 sf entered as “Educational – Elementary School” with 370 students, and • 98,000 sf entered as “Parking – Other Asphalt Surfaces.” Traffic generation were provided by the traffic consultant.10 Summary of Computed Operational Period Emissions Annual emissions were predicted using CalEEMod and daily emissions were estimating assuming 365 days of operation. Table 4 shows average daily emissions of ROG, NOX, total PM10, and total PM2.5 during operation of the project. The operational period emissions would not exceed the BAAQMD significance thresholds. Emissions from the project are anticipated to be less than the existing uses with the school operating for all pollutants except ROG. Table 4.

Project impacts related to increased community risk occur since the project is a new source of TACs during construction and operation with the potential to adversely affect existing sensitive receptors in the project vicinity. This project would generate dust and introduce new sources of TACs during construction (i.e., equipment exhausts from construction activity and truck hauling emissions) that would affect nearby sensitive receptors. Long-term operation of the project would generate localized TAC emissions that are considered negligible based on the low volume of traffic generated and the type of traffic. Residential traffic includes light-duty automobiles that have low emission rates of TACs. Note that the project replaces a school that produced higher localized volumes of traffic. Therefore, project impacts to both existing sensitive receptors were assessed given temporary construction activities. Note the analysis of new sensitive receptors introduced by the project is provided for informational purposes only. Community Risk Methodology for Construction Construction equipment and associated heavy-duty truck traffic generates diesel exhaust, which is a known TAC. Although it was concluded in the previous sections (see Table 3) that construction exhaust air pollutant emissions would not be considered to contribute substantially to existing or projected air quality violations, construction exhaust emissions may still pose health risks for sensitive receptors such as surrounding residents. Community risk impacts are addressed by predicting increased lifetime cancer risk, the increase in annual PM2.5 concentrations, and computing the Hazard Index (HI) for non-cancer health risks. Construction equipment and associated heavy-duty truck traffic generates diesel exhaust, which is a known TAC. The primary community risk impact issues associated with construction emissions are cancer risk and exposure to PM2.5 concentrations. These emissions pose health risks for sensitive receptors such as surrounding residents. A health risk assessment of the project construction activities was conducted that evaluated potential health effects to nearby sensitive receptors from construction emissions of DPM and PM2.5.11 For this assessment, PM10 exhaust emissions from construction equipment and truck traffic were assumed to be DPM. This assessment included dispersion modeling to predict the offsite concentrations resulting from project construction, so that lifetime cancer risks and non-cancer health effects could be evaluated. The methodology for computing community risks impacts is contained in Attachment 1. Construction Period Emissions The CalEEMod model provided total annual PM10 exhaust emissions (assumed to be DPM) for the off-road construction equipment, while EMFAC2017 was used to estimate emissions from on- road activities. On-road emissions are a result of haul truck travel during demolition and grading activities, worker travel, and vendor deliveries. A trip length of one (1) mile was used to represent vehicle travel while at or near the construction site. It was assumed emissions from on-road vehicles traveling at or near the site would occur at the construction site. The total emissions from construction (on and off road) were estimated to be approximately 0.12 tons (246 pounds). Fugitive PM2.5 dust emissions were calculated in the same way described above and estimated to be approximately 0.1 tons (177 pounds). 11 DPM is identified by California as a toxic air contaminant due to the potential to cause cancer. 14 Dispersion Modeling The U.S. EPA AERMOD dispersion model was used to predict DPM and PM2.5 concentrations at sensitive receptors (i.e., residents) in the vicinity of the project construction area. The AERMOD dispersion model is a BAAQMD-recommended model for use in modeling ambient impacts of these types of emission activities for CEQA projects.12 Emission sources for the construction site were grouped into two categories: exhaust emissions of DPM and fugitive PM2.5 dust emissions. Combustion equipment exhaust emissions were modeled as a series of point sources with a 9-foot release height (construction equipment exhaust stack height) placed at 16.4-feet (5-meter) intervals throughout the construction site. This resulted in 972 individual point sources being used to represent mobile equipment DPM exhaust emissions in the construction area, with DPM emissions occurring throughout the project construction site. Construction fugitive PM2.5 dust emissions were modeled as an area source encompassing the entire construction site with a near ground level release height of 7 feet (2 meters). Construction emissions were modeled as occurring daily between 7:00 a.m. to 4:00 p.m. when most of the construction activity would occur. The modeling used a five-year data set (2012-2015 and 2017) of hourly meteorological data from Buchanan Field Airport in Concord, CA that was prepared for use with the AERMOD model by BAAQMD. The Buchanan Field is approximately 4 miles north from the project site. Annual DPM and PM2.5 concentrations from construction activities were calculated at nearby sensitive receptors using the model. Receptor heights of 5 feet (1.5 meters) and 15 feet (4.55 meters) were used to represent the breathing heights at nearby multifamily homes. Project Construction Community Risk Impacts The modeled maximum annual DPM and PM2.5 concentrations, which includes fugitive dust emissions, were identified at nearby sensitive receptors (as shown in Figure 1) to find the maximally exposed individuals (MEIs). Using the maximum annual modeled DPM concentrations, the maximum increased cancer risks were calculated using BAAQMD recommended methods and exposure parameters described in Attachment 1. Non-cancer health hazards and maximum annual PM2.5 concentrations were also calculated. Attachment 4 to this report includes the emission calculations used for the construction area source modeling and the cancer risk calculations. Results of this assessment indicated that the highest concentration of construction related DPM and fugitive PM2.5, and thus the MEI, was located at a multifamily residence adjacent to the northern project boundary. DPM concentrations were highest on the second floor, while fugitive PM2.5 concentrations were highest on the first floor (see Figure 1). The unmitigated maximum increased cancer risk from construction was 16.3 per million at the MEI. The maximum annual PM2.5 concentration from construction was 0.45 µg/m3 occurring during the 2022-2023 construction period. Both exceed their respective BAAQMD single-source thresholds of greater than 10.0 in a million and greater than 0.3 µg/m3 for PM2.5 concentration. 12 Bay Area Air Quality Management District (BAAQMD), 2012, Recommended Methods for Screening and Modeling Local Risks and Hazards, Version 3.0. May. 15 Figure 1. Project Construction Site, Locations of Off-Site Sensitive Receptors, and Locations of TAC Impacts However, with the incorporation of Mitigation Measure AQ-1 and AQ-2 (discussed below), the increased project cancer risk and PM2.5 concentration would not exceed their single-source thresholds. Both the unmitigated and mitigated non-cancer hazards from construction activities would be below the single-source significance threshold of 1.0. Table 5 summarizes the maximum cancer risks, PM2.5 concentrations, and health hazard indexes for project related construction activities. Table 5. Construction Risk Impacts at the Off-Site Residential MEIs Source Cancer Risk (per million) Annual PM2.5 (µg/m3) Hazard Index Project Construction Unmitigated Mitigated* 16.3 (infant) 1.8 (infant) 0.45 0.19 0.01 <0.01 BAAQMD Single-Source Threshold >10.0 >0.3 >1.0 Exceed Threshold? Unmitigated Mitigated* Yes No Yes No No No * Mitigation Measures include construction equipment engines with Tier 4 Interim emissions limits and BAAQMD’s enhanced BMPs for fugitive dust. Mitigation Measure AQ-2 would reduce construction-related DPM to the levels needed to meet the health risk assessment thresholds for both cancer risk and PM2.5 concentration. 16 Combined Impact of All TAC Sources on the Off-Site Construction MEI Community health risk assessments typically look at all substantial sources of TACs that can affect sensitive receptors that are located within 1,000 feet of the project site (i.e., influence area). These sources include railroads, freeways or highways, busy surface streets, and stationary sources identified by BAAQMD. A review of the project area identified several sources of TACs near the project. They include: Interstate 680 (I-680), the northbound off ramp, a truck weigh station, Oak Road, Treat Boulevard, and six stationary sources (i.e., diesel powered emergency generators). All other roadways within the area are considered low-volume roadways (i.e., below 10,000 average daily traffic, or ADT) and, therefore, not a significant source of TACs. Figure 2 shows the TAC sources affecting the project site. Community risk impacts from these sources upon the construction MEI are reported in Table 6. Details of the emissions modeling and community risk calculations are included in Attachment 5 and Attachment 6. Figure 2. Project Site and Nearby TAC and PM2.5 Sources Freeways – I-680 Both the project site and construction MEI are near I-680. A refined analysis of the impacts of TACs and PM2.5 from I-680 on the project site and construction MEI was conducted to assess potential cancer risks and PM2.5 concentrations associated with interstate traffic. A review of the traffic census information reported by the California Department of Transportation (Caltrans) for 2019 indicates that I-680 had an average annual daily traffic (AADT) volume of 291,000 vehicles per day (based on 2019 measurements) that are about 3.23 percent trucks, of which 1.7 percent are 17 considered diesel heavy duty trucks and 1.5 percent are medium duty trucks.13 Northbound off ramp volumes were also estimated using Caltrans’ Traffic Census Program data and were determined to be approximately 7.1 percent of the mainline volume. Traffic volumes were grown from 2019 estimates to 2023 assuming an increase of one percent per year. Modeling I-680 Emissions Analysis of I-680 involved developing emissions estimates of DPM, organic TACs (as TOG), and PM2.5 emissions estimates using the Caltrans version of the CARB’s EMFAC2017 emissions model, known as CT-EMFAC2017. CT-EMFAC2017 provides emission factors for mobile source criteria pollutants and TACs, including DPM. Emission processes modeled include running exhaust for DPM, PM2.5 and total organic compounds (e.g., TOG), running evaporative losses for TOG, and fugitive road dust for PM2.5 that includes tire and brake wear emissions. In general, vehicle fleet emissions are projected to decrease in the future as reflected in the CT-EMFAC2017 emissions estimates. Inputs to the emissions model include region (i.e., Contra Costa County), type of road (i.e., freeway), traffic mix assigned by CT-EMFAC2017 for the county and adjusted for the local truck mix on I-680, year of analysis (i.e., 2023), and season (i.e., annual). CT-EMFAC2017 was used to develop vehicle emission factors for the year 2023 using the mix of vehicles in Contra Costa County to estimate TAC and PM2.5 emissions over the 30-year exposure period used for calculating increased cancer risks from traffic on I-680. Emissions associated with vehicle travel depend on the year of analysis because emission control technology requirements are phased-in over time. Therefore, the earlier the year analyzed in the model, the higher the emission rates produced by CT-EMFAC2017. Year 2023 emissions were conservatively assumed as being representative of future conditions over the time period that cancer risks are evaluated (30 years), since, as discussed above, overall vehicle emissions, in particular diesel truck emissions will decrease in the future. Hourly traffic distributions specific to this segment of I-680 were obtained from Caltrans Performance Measurement System (PeMS). PeMS data is collected in real- time from nearly 40,000 individual detectors spanning the freeway system across all major metropolitan areas of California 14. The fraction of traffic volume each hour in 2019 was calculated and applied to the AADT estimate to estimate hourly traffic emission rates for I-680. For all hours of the day, other than during peak a.m. and p.m. periods, an average speed of 65 mph was assumed for northbound and southbound vehicles. Based on weekday 2019 speed data from PeMS, traffic speeds on northbound and southbound I-680 in the vicinity of the project site during the peak a.m. and p.m. periods were identified. For the 2-hour period during the peak a.m. period, the average northbound speed was approximately 65 mph while the average southbound speed was 25 mph. During the 2-hour peak p.m. period, the average travel speed in the northbound direction was approximately 30 mph and 60 mph in the southbound direction. Northbound off ramp speeds were assumed to average 35 mph, regardless of the time of day. Hourly emissions rates were developed for DPM, organic TACs, and PM2.5 emissions for 2023 traffic along this segment of I-680 and the northbound off ramp. TAC and PM2.5 concentrations at the construction MEI location were developed using these emissions rates with an air quality dispersion model (AERMOD). Maximum increased lifetime cancer risks and annual PM2.5 13 Caltrans. 2021. 2019 Annual Average Daily Truck Traffic on the California State Highway System 14 https://dot.ca.gov/programs/traffic-operations/mpr/pems-source 18 concentrations for the receptors were then computed using modeled TAC and PM2.5 concentrations and BAAQMD methods and exposure parameters described in Attachment 1. Dispersion Modeling Dispersion modeling of TAC and PM2.5 emissions was conducted using the U.S. EPA AERMOD dispersion model, which is recommended by the BAAQMD for this type of analysis. Northbound and southbound traffic on I-680 within about 1,000 feet of the project site was evaluated with the model. Emissions from vehicle traffic were modeled in AERMOD using a series of volume sources along a line (line volume sources), with line segments used to represent northbound and southbound travel lanes on I-680 and the northbound off ramp. The modeling used a five-year data set (2012-2015 and 2017) of hourly meteorological data from Buchanan Field Airport in Concord, CA prepared by the BAAQMD for use with the AERMOD model. Other inputs to the model included road geometry and elevations, hourly traffic emissions, and receptor locations and heights. Figure 2 shows the roadway links used for the modeling and receptor location at the construction MEI where concentrations were calculated. Computed Cancer and Non-Cancer Health Impacts of I-680 The maximum increased cancer risk and maximum PM2.5 concentration at the construction MEIs are shown in Table 6. Maximum increased cancer risk associated with I-680 and the northbound off ramp at the construction MEI receptor would be 16.3 in one million, the maximum PM2.5 concentration at the receptor with the highest construction-related annual PM2.5 concentration would be 0.69 μg/m3, and the HI at the construction MEI location would be less than 0.01. Details of the emission calculations, dispersion modeling and cancer risk calculations for the receptors with the maximum impacts are provided in Attachment 5 and Attachment 6. Local Roadways – Oak Road and Treat Boulevard The project site and construction MEI are near the high-volume roadways (i.e., roadways with daily traffic volumes more than 10,000 ADT) of Oak Road and Treat Boulevard. A refined analysis of the impacts of TACs and PM2.5 from these local roadways on the construction MEI is necessary to evaluate potential cancer risks and PM2.5 concentrations associated with them. Traffic information for these roadways were not readily available, as a traffic study is currently underway. Therefore, it was assumed Oak Road has an ADT of 20,000 vehicles a day and Treat Boulevard has an ADT of 40,000. The hourly traffic distributions used for the analysis of I-680 were used to estimate hourly traffic distributions on the local roadways. Likewise, the truck percentages used to analyze I-680 were used to estimate the truck traffic percentages on the local roadways. Modeling Local Roadway Emissions Analysis of the nearby roadways involved developing emissions estimates of DPM, organic TACs (as TOG), and PM2.5 emissions for 2023 using CT-EMFAC2017. Emission processes modeled include running exhaust for DPM, PM2.5 and total organic compounds (e.g., TOG), running evaporative losses for TOG, and fugitive road dust for PM2.5 that includes tire and brake wear emissions. Inputs to the emissions model include region (i.e., Contra Costa County), type of road (i.e., major/collector), traffic mix assigned by CT-EMFAC2017 for the county, year of analysis (i.e., 2023), and season (i.e., annual). Year 2023 emissions were conservatively assumed as being 19 representative of future conditions over the period that cancer risks are evaluated (30 years), since, as previously discussed, overall vehicle emissions, in particular diesel truck emissions, will decrease in the future. Hourly traffic distributions specific for each roadway were obtained by averaging 2019 hourly traffic volumes from I-680 using PeMS data. The fraction of traffic volume each hour was calculated and applied to the daily traffic estimates for each roadway to obtain hourly traffic emission rates. For all hours of the day, other than during peak a.m. and p.m. periods, an average speed of 35 mph was assumed for both Oak Road and Treat Boulevard. Traffic speeds during the peak a.m. and p.m. periods were assumed to be 5 miles per hour slower on Oak Road and 10 mph slower on Treat Boulevard, based on the amount of access provided by each roadway. Hourly emissions rates were developed for DPM, organic TACs, and PM2.5 emissions for 2023 traffic along the applicable segments of each roadway within approximately 1,000 feet of the project site. TAC and PM2.5 concentrations at the construction MEI location were developed using these emissions rates with an air quality dispersion model (AERMOD). Maximum increased lifetime cancer risks and maximum annual PM2.5 concentrations for the receptors were then computed using modeled TAC and PM2.5 concentrations and BAAQMD methods and exposure parameters described in Attachment 1. NOTE TO READER: CT-EMFAC2017 was used to estimate emissions from roadways. Caltrans has not issued a new version of CT-EMFAC that incorporates EMFAC2021 as of the date of this analysis (5/13/2021). EMFAC2021 PM2.5 emission rates in future years tend to be much lower than those provided by CT-EMFAC2017, primarily due to improved methods for estimating brake wear on highways. Therefore, fugitive PM2.5 concentrations from roadways are overpredicted in this assessment. Dispersion Modeling Dispersion modeling of TAC and PM2.5 emissions was conducted using the U.S. EPA AERMOD dispersion model, which is recommended by the BAAQMD for this type of analysis. Roadway traffic within approximately 1,000 feet of the project site was evaluated with the model. Emissions from vehicle traffic were modeled using a series of area sources along a line (line area sources), with line segments used to represent travel lanes. The modeling used a five-year data set (2012- 2015 and 2017) of hourly meteorological data from the Buchanan Field Airport in Concord, CA prepared by the BAAQMD for use with the AERMOD model. Other inputs to the model included road geometry and elevations, hourly traffic emissions, and receptor locations and heights. Figure 2 shows the roadway links used for the modeling and receptor locations where concentrations were calculated. Computed Cancer and Non-Cancer Health Impacts of Local Roadways The maximum increased cancer risk associated with Oak Road at the construction MEI receptor would be 1.7 in one million, the maximum PM2.5 concentration at the receptor with the highest annual construction related PM2.5 concentration would be 0.22 μg/m3, and the HI at the construction MEI location would be less than 0.01. Likewise, the maximum increased cancer risk associated with Treat Boulevard at the construction MEI receptor would be 0.3 in one million. 20 Maximum annual PM2.5 concentrations from Treat Boulevard at the receptor with the highest construction related annual PM2.5 concentration would be 0.06 μg/m3 the HI would be less than 0.01. The risk impacts from these roadways on the construction MEI are shown in Table 6. Details of the emission calculations, dispersion modeling and cancer risk calculations for the receptor with the maximum cancer risk from local roadway traffic are provided in Attachment 5 and Attachment 6. Truck Weigh Station A weigh station for northbound trucks is located adjacent to I-680, approximately 460 feet from the project site. Emissions from weigh station operations were estimated using CT-EMFAC2017 and its impacts on the construction MEI estimated using AERMOD. Modeling Weigh Station Emissions Analysis of the weigh station emissions involved developing estimates of DPM for 2023 using CT-EMFAC2017 assuming a 100 percent truck fraction. CT-EMFAC2017 inputs include region (i.e., Contra Costa County), type of road (i.e., local/urban), year of analysis (i.e., 2023), and season (i.e., annual). Year 2023 emissions were conservatively assumed as being representative of future conditions over the period that cancer risks are evaluated (30 years), since, as previously discussed, overall vehicle emissions, in particular diesel truck emissions, will decrease in the future. Daily truck traffic volumes were estimated to be the truck fraction of the I-680 northbound off ramp, with 50 percent of the trucks stopping to weigh, and the other 50 percent passing by the weigh station at 5 mph. Hourly traffic distributions for the weigh station were obtained by averaging 2019 hourly traffic volumes from I-680 using PeMS data. Trucks being weighed were assumed to stop and idle for 1 minute. Dispersion Modeling Dispersion modeling of DPM emissions was conducted using AERMOD, the dispersion model recommended by the BAAQMD for this type of analysis. Emissions from weigh station operations were modeled using a series of volume sources along a line (line volume sources), with line segments used to represent the truck travel lane and an area source to represent truck idling during weighing. The modeling used a five-year data set (2012-2015 and 2017) of hourly meteorological data from the Buchanan Field Airport in Concord, CA prepared by the BAAQMD for use with the AERMOD model. Other inputs to the model included lane geometry, hourly truck emissions, and receptor locations and heights. Figure 2 shows the links and area source used to model the weigh station and receptor locations where concentrations were calculated. Computed Cancer and Non-Cancer Health Impacts of The Weigh Station The maximum increased cancer risk associated with operation of the weigh station at the construction MEI receptor would be 0.3 in one million, the maximum PM2.5 concentration at the receptor with the highest annual construction related PM2.5 concentration would be less than 0.001 μg/m3, and the HI at the construction MEI location would be less than 0.01. The risk impacts from the weigh station on the construction MEI are shown in Table 6. Details of the emission 21 calculations, dispersion modeling and cancer risk calculations for the construction MEI are provided in Attachment 5 and Attachment 6. Stationary Sources Permitted stationary sources of air pollution near the project site are identified using BAAQMD’s Permitted Stationary Sources 2018 GIS website,15 which provides the location of nearby stationary sources and their estimated risk and hazard impacts, including emissions and adjustments to account for new OEHHA guidance. Six existing stationary sources of TACs were identified within 1,000 feet of the project; all of them diesel powered generators. They are: • Facility 14070 – SF Bay Area Rapid Transit District Generator • Facility 14101 – AT&T Services, Inc. Generator • Facility 14581 – Jones Lang LaSalle Generator • Facility 19737 – Avalon Bay Communities, Inc. Generator • Facility 22052 – MLM Treat Towers Generator • Facility 23059 – Level 3 Communications LLC Generator A Stationary Source Information Form (SSIF) containing the identified sources was prepared and submitted to BAAQMD. BAAQMD provided input and clarification about the stationary sources.16 The average daily emissions provided by BAAQMD for each of the sources were adjusted for distance using BAAQMD’s Distance Adjustment Multiplier Tool for Diesel Internal Combustion Engines, Gasoline Dispensing Facility Distance Multiplier Tool, or Generic Distance Multiplier Tool when appropriate. Results from the screening calculator are listed in Table 6. Combined Community Health Risk at Off-Site Construction MEI Table 6 reports both the project and cumulative community risk impacts at the sensitive receptors most affected by construction (i.e., the construction MEI and receptor with the highest annual construction related PM2.5 concentration). Without mitigation, the project’s community risk from project construction activities would exceed the single-source maximum cancer risk and annual PM2.5 concentration significance thresholds but would not exceed the HI significance threshold. With the incorporation of Mitigation Measures AQ-1 and AQ-2, the project does not exceed single- source thresholds. The cumulative cancer risks and maximum HI would not exceed their thresholds given either the unmitigated or mitigated condition. The combination of existing sources in the area results in an annual PM2.5 concentration of 0.97 μg/m3, which exceeds the cumulative threshold of 0.8 μg/m3. Therefore, the cumulative annual PM2.5 concentration with the project impact would also exceed the significance threshold of greater than 0.8 μg/m3 for both the unmitigated and mitigated condition. This is primarily the caused by emissions from I-680. 15 BAAQMD, Permitted Stationary Sources 2018 GIS website https://baaqmd.maps.arcgis.com/apps/webappviewer/index.html?id=2387ae674013413f987b1071715daa65 16 Correspondence with Areana Flores, MSc, Environmental Planner, BAAQMD, January 6, 2021. 22 Table 6.

Mitigation Measure AQ-2: Selection of equipment during construction to minimize DPM emissions. The project shall implement the following: • All diesel-powered off-road equipment, larger than 25 horsepower, operating on the site for more than two days continuously shall, at a minimum, meet U.S. EPA particulate matter emissions standards for Tier 4 engines. Where Tier 4 equipment is not available, exceptions could be made for equipment meeting Tier 2 or Tier 3 standards that include CARB-certified Level 3 Diesel Particulate Filters or equivalent. Equipment that is electrically powered or uses non-diesel fuels would also meet this requirement. • Minimize diesel generator use by providing line power to the site during early construction phases. • Avoid staging construction equipment near residences (i.e., within 200 feet of homes). Effectiveness of Mitigation Measure AQ-1 and AQ-2 23 CalEEMod was used to compute emissions associated with construction equipment mitigation measures (MM AQ-1 and AQ-2) if all equipment meets U.S. EPA Tier 4 engines standards for particulate matter emissions (or equivalent). Implementation of Mitigation Measure AQ-1, which includes enhanced controls measures for fugitive dust, would reduce fugitive PM2.5 emissions by over 80 percent. With the implementation of Mitigation Measure AQ-2, exhaust PM2.5 emissions (assumed to be DPM emissions) from construction would be reduced by as much as 91 percent. Cancer risk associated with construction would be reduced below both the single and cumulative thresholds. Annual PM2.5 concentrations would be reduced well below the single source threshold, but it is not possible to reduce the levels below the cumulative threshold since existing non-project sources cause concentrations to exceed the cumulative threshold. Since the project would implement enhanced control measures to reduce PM2.5 emissions and the project contribution would be well below the single source threshold, the project contribution is not considered to be considerable. Implementation of Mitigation Measures AQ-1 and AQ-2 would reduce this impact to less than significant. 24 GREENHOUSE GAS EMISSIONS Setting Gases that trap heat in the atmosphere, GHGs, regulate the earth’s temperature. This phenomenon, known as the greenhouse effect, is responsible for maintaining a habitable climate. The most common GHGs are carbon dioxide (CO2) and water vapor but there are also several others, most importantly methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). These are released into the earth’s atmosphere through a variety of natural processes and human activities. Sources of GHGs are generally as follows: • CO2, CH4, and N2O are byproducts of fossil fuel combustion. • N2O is associated with agricultural operations such as fertilization of crops. • CH4 is commonly created by off-gassing from agricultural practices (e.g., keeping livestock) and landfill operations. • Chlorofluorocarbons (CFCs) were widely used as refrigerants, propellants, and cleaning solvents but their production has been stopped by international treaty. • HFCs are now used as a substitute for CFCs in refrigeration and cooling. • PFCs and sulfur hexafluoride emissions are commonly created by industries such as aluminum production and semi-conductor manufacturing. Each GHG has its own potency and effect upon the earth’s energy balance. This is expressed in terms of a global warming potential (GWP), with CO2 being assigned a value of 1 and sulfur hexafluoride being several orders of magnitude stronger. In GHG emission inventories, the weight of each gas is multiplied by its GWP and is measured in units of CO2 equivalents (CO2e). An expanding body of scientific research supports the theory that global climate change is currently affecting changes in weather patterns, average sea level, ocean acidification, chemical reaction rates, and precipitation rates, and that it will increasingly do so in the future. The climate and several naturally occurring resources within California are adversely affected by the global warming trend. Increased precipitation and sea level rise will increase coastal flooding, saltwater intrusion, and degradation of wetlands. Mass migration and/or loss of plant and animal species could also occur. Potential effects of global climate change that could adversely affect human health include more extreme heat waves and heat-related stress; an increase in climate-sensitive diseases; more frequent and intense natural disasters such as flooding, hurricanes and drought; and increased levels of air pollution. Recent Regulatory Actions for GHG Emissions Executive Order S-3-05 – California GHG Reduction Targets Executive Order (EO) S-3-05 was signed by Governor Arnold Schwarzenegger in 2005 to set GHG emission reduction targets for California. The three targets established by this EO are as follows: (1) reduce California’s GHG emissions to 2000 levels by 2010, (2) reduce California’s GHG emissions to 1990 levels by 2020, and (3) reduce California’s GHG emissions by 80 percent below 1990 levels by 2050. 25 Assembly Bill 32 – California Global Warming Solutions Act (2006) Assembly Bill (AB) 32, the Global Warming Solutions Act of 2006, codified the State’s GHG emissions target by directing CARB to reduce the State’s global warming emissions to 1990 levels by 2020. AB 32 was signed and passed into law by Governor Schwarzenegger on September 27, 2006. Since that time, the CARB, CEC, California Public Utilities Commission (CPUC), and Building Standards Commission have all been developing regulations that will help meet the goals of AB 32 and Executive Order S-3-05, which has a target of reducing GHG emissions 80 percent below 1990 levels. A Scoping Plan for AB 32 was adopted by CARB in December 2008. It contains the State’s main strategies to reduce GHGs from business-as-usual emissions projected in 2020 back down to 1990 levels. Business-as-usual (BAU) is the projected emissions in 2020, including increases in emissions caused by growth, without any GHG reduction measures. The Scoping Plan has a range of GHG reduction actions, including direct regulations, alternative compliance mechanisms, monetary and non-monetary incentives, voluntary actions, and market-based mechanisms such as a cap-and-trade system. As directed by AB 32, CARB has also approved a statewide GHG emissions limit. On December 6, 2007, CARB staff resolved an amount of 427 million metric tons (MMT) of CO2e as the total statewide GHG 1990 emissions level and 2020 emissions limit. The limit is a cumulative statewide limit, not a sector- or facility-specific limit. CARB updated the future 2020 BAU annual emissions forecast, due to the economic downturn, to 545 MMT of CO2e. Two GHG emissions reduction measures currently enacted that were not previously included in the 2008 Scoping Plan baseline inventory were included, further reducing the baseline inventory to 507 MMT of CO2e. Thus, an estimated reduction of 80 MMT of CO2e is necessary to reduce statewide emissions to meet the AB 32 target by 2020. Executive Order B-30-15 & Senate Bill 32 GHG Reduction Targets – 2030 GHG Reduction Target In April 2015, Governor Brown signed EO B-30-15, which extended the goals of AB 32, setting a greenhouse gas emissions target at 40 percent of 1990 levels by 2030. On September 8, 2016, Governor Brown signed Senate Bill (SB) 32, which legislatively established the GHG reduction target of 40 percent of 1990 levels by 2030. In November 2017, CARB issued California’s 2017 Climate Change Scoping Plan. 17 While the State is on track to exceed the AB 32 scoping plan 2020 targets, this plan is an update to reflect the enacted SB 32 reduction target. SB 32 was passed in 2016, which codified a 2030 GHG emissions reduction target of 40 percent below 1990 levels. CARB is currently working on a second update to the Scoping Plan to reflect the 2030 target set by Executive Order B-30-15 and codified by SB 32. The proposed Scoping Plan Update was published on January 20, 2017 as directed by SB 32 companion legislation AB 197. The mid-term 2030 target is considered critical by CARB on the path to obtaining an even deeper GHG emissions target of 80 percent below 1990 levels by 2050, as directed in Executive Order S-3-05. The Scoping Plan outlines the suite of policy measures, regulations, planning efforts, 17 California Air Resource Board, 2017. California’s 2017 Climate Change Scoping Plan: The Strategy for Achieving California’s 2030 Greenhouse Gas Targets. November. Web: https://ww2.arb.ca.gov/sites/default/files/classic//cc/scopingplan/scoping_plan_2017.pdf 26 and investments in clean technologies and infrastructure, providing a blueprint to continue driving down GHG emissions and obtain the statewide goals. The new Scoping Plan establishes a strategy that will reduce GHG emissions in California to meet the 2030 target (note that the AB 32 Scoping Plan only addressed 2020 targets and a long-term goal). Key features of this plan are: • Cap and Trade program places a firm limit on 80 percent of the State’s emissions. • Achieving a 50-percent Renewable Portfolio Standard by 2030 (currently at about 29 percent statewide). • Increase energy efficiency in existing buildings. • Develop fuels with an 18-percent reduction in carbon intensity. • Develop more high-density, transit-oriented housing. • Develop walkable and bikeable communities. • Greatly increase the number of electric vehicles on the road and reduce oil demand in half. • Increase zero-emissions transit so that 100 percent of new buses are zero emissions. • Reduce freight-related emissions by transitioning to zero emissions where feasible and near-zero emissions with renewable fuels everywhere else. • Reduce “super pollutants” by reducing methane and hydrofluorocarbons or HFCs by 40 percent. In the updated Scoping Plan, CARB recommends statewide targets of no more than 6 metric tons CO2e per capita (statewide) by 2030 and no more than 2 metric tons CO2e per capita by 2050. The statewide per capita targets account for all emissions sectors in the State, statewide population forecasts, and the statewide reductions necessary to achieve the 2030 statewide target under SB 32 and the longer-term State emissions reduction goal of 80 percent below 1990 levels by 2050. Executive Order B-55-18 – Carbon Neutrality In 2018, a new statewide goal was established to achieve carbon neutrality as soon as possible, but no later than 2045, and to maintain net negative emissions thereafter. CARB and other relevant state agencies are tasked with establishing sequestration targets and create policies/programs that would meet this goal. Senate Bill 375 – California's Regional Transportation and Land Use Planning Efforts (2008) California enacted legislation (SB 375) to expand the efforts of AB 32 by controlling indirect GHG emissions caused by urban sprawl. SB 375 provides incentives for local governments and applicants to implement new conscientiously planned growth patterns. This includes incentives for creating attractive, walkable, and sustainable communities and revitalizing existing communities. The legislation also allows applicants to bypass certain environmental reviews under CEQA if they build projects consistent with the new sustainable community strategies. Development of more alternative transportation options that would reduce vehicle trips and miles traveled, along with traffic congestion, would be encouraged. SB 375 enhances CARB’s ability to reach the AB 32 goals by directing the agency in developing regional GHG emission reduction targets to be achieved from the transportation sector for 2020 and 2035. CARB works with the metropolitan planning organizations (e.g., Association of Bay Area Governments [ABAG] and Metropolitan 27 Transportation Commission [MTC]) to align their regional transportation, housing, and land use plans to reduce vehicle miles traveled and demonstrate the region's ability to attain its GHG reduction targets. A similar process is used to reduce transportation emissions of ozone precursor pollutants in the Bay Area. Senate Bill 350 - Renewable Portfolio Standards In September 2015, the California Legislature passed SB 350, which increases the states Renewables Portfolio Standard (RPS) for content of electrical generation from the 33 percent target for 2020 to a 50 percent renewables target by 2030. Senate Bill 100 – Current Renewable Portfolio Standards In September 2018, SB 100 was signed by Governor Brown to revise California’s RPS program goals, furthering California’s focus on using renewable energy and carbon-free power sources for its energy needs. The bill would require all California utilities to supply a specific percentage of their retail sales from renewable resources by certain target years. By December 31, 2024, 44 percent of the retails sales would need to be from renewable energy sources, by December 31, 2026 the target would be 40 percent, by December 31, 2017 the target would be 52 percent, and by December 31, 2030 the target would be 60 percent. By December 31, 2045, all California utilities would be required to supply retail electricity that is 100 percent carbon-free and sourced from eligible renewable energy resource to all California end-use customers. California Building Standards Code – Title 24 Part 11 & Part 6 The California Green Building Standards Code (CALGreen Code) is part of the California Building Standards Code under Title 24, Part 11.18 The CALGreen Code encourages sustainable construction standards that involve planning/design, energy efficiency, water efficiency resource efficiency, and environmental quality. These green building standard codes are mandatory statewide and are applicable to residential and non-residential developments. The most recent CALGreen Code (2019 California Building Standard Code) was effective as of January 1, 2020. The California Building Energy Efficiency Standards (California Energy Code) is under Title 24, Part 6 and is overseen by the California Energy Commission (CEC). This code includes design requirements to conserve energy in new residential and non-residential developments, while being cost effective for homeowners. This Energy Code is enforced and verified by cities during the planning and building permit process. The current energy efficiency standards (2019 Energy Code) replaced the 2016 Energy Code as of January 1,2020. Under the 2019 standards, single-family homes are predicted to be 53 percent more efficient than homes built under the 2016 standard due more stringent energy-efficiency standards and mandatory installation of solar photovoltaic systems. For nonresidential developments, it is predicted that these buildings will use 30 percent less energy due to lightening upgrades.19 18 See: https://www.dgs.ca.gov/BSC/Resources/Page-Content/Building-Standards-Commission-Resources-List- Folder/CALGreen#:~:text=CALGreen%20is%20the%20first%2Din,to%201990%20levels%20by%202020. 19 See: https://www.energy.ca.gov/sites/default/files/2020-03/Title_24_2019_Building_Standards_FAQ_ada.pdf 28 Federal and Statewide GHG Emissions The U.S. EPA reported that in 2018, total gross nationwide GHG emissions were 6,676.6 million metric tons (MMT) carbon dioxide equivalent (CO2e).20 These emissions were lower than peak levels of 7,416 MMT that were emitted in 2007. CARB updates the statewide GHG emission inventory on an annual basis where the latest inventory includes 2000 through 2017 emissions.21 In 2017, GHG emissions from statewide emitting activities were 424 MMT. The 2017 emissions have decreased by 14 percent since peak levels in 2004 and are 7 MMT below the 1990 emissions level and the State’s 2020 GHG limit. Per capita GHG emissions in California have dropped from a 2001 peak of 14.1 MT per person to 10.7 MT per person in 2017. The most recent Bay Area emission inventory was computed for the year 2011.22 The Bay Area GHG emission were 87 MMT. As a point of comparison, statewide emissions were about 444 MMT in 2011. Contra Costa County Climate Action Plan The Contra Costa County Board of Supervisors adopted the county’s current Climate Action Plan (CAP) on December 15, 2015.23 The Climate Action Plan is a qualified plan and demonstrates the county’s commitment to addressing the challenges of climate change. The CAP outlines the county's overall strategies for reducing greenhouse gas emissions in response to state regulations to address climate change. The CAP outlines ways in which the county can prepare for and adapt to the consequences of climate change, and provides energy use, transportation, land use, and solid waste strategies to reduce Contra Costa’s GHG emissions. The CAP has a GHG reduction target of 15% from 2005 levels by the year 2020. In addition, the CAP forecasts the potential GHG emissions and estimated GHG reductions from proposed measures through 2035 to the level specified in EO B-30-15. Such a goal is equal to 50% below 1990 levels, or approximately 57% below baseline levels. As part of the CAP, the county developed a development checklist (i.e., Appendix E to the CAP) to help both project applicants and County staff determine where a proposed new development project is consistent with Contra Costa County’s CAP. The checklist should be completed for each project subject to discretionary review. The criterion in the checklist clarifies implementation of the CAP and explain how a project can comply. The checklist is provided in Attachment 7. BAAQMD Significance Thresholds For quantified emissions, the BAAQMD’s CEQA Air Quality Guidelines recommended a GHG threshold of 1,100 metric tons or 4.6 metric tons (MT) per capita. These thresholds were developed based on meeting the 2020 GHG targets set in the scoping plan that addressed AB 32. Development 20 United States Environmental Protection Agency, 2020.

Although BAAQMD has not published a quantified threshold for 2030 yet, this assessment uses a “Substantial Progress” efficiency metric of 2.8 MT CO2e/year/service population and a bright-line threshold of 660 MT CO2e/year based on the GHG reduction goals of EO B-30-15. The service population metric of 2.6 is calculated for 2030 based on the 1990 inventory and the projected 2030 statewide population and employment levels.24 The 2030 bright-line threshold is a 40 percent reduction of the 2020 1,100 MT CO2e/year threshold. Impact: Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? GHG emissions associated with development of the proposed project would occur over the short- term from construction activities, consisting primarily of emissions from equipment exhaust and worker and vendor trips. There would also be long-term operational emissions associated with vehicular traffic within the project vicinity, energy and water usage, and solid waste disposal. Emissions for the proposed project are discussed below and were analyzed using the methodology recommended in the BAAQMD CEQA Air Quality Guidelines. CalEEMod Modeling CalEEMod was used to predict GHG emissions from operation of the site assuming full build-out of the project. The project land use types and size and other project-specific information were input to the model, as previously described. CalEEMod output is included in Attachment 2. Existing Uses A CalEEMod run was developed to estimate GHG emissions assuming the Palmer School was still in operation. This is a common, valid baseline approach under CEQA since the school was operational into 2020 and could choose to reopen instead of selling and the GHG emissions from the school operation would continue to be part of the environment. Inputs for this modeling scenario were estimated using the trip estimates provide by the traffic consultant and included: • 30,930 sf entered as “Educational – Elementary School” with 370 students, and • 98,000 sf entered as “Parking – Other Asphalt Surfaces.” These land use inputs along with the other operational inputs described above were applied to the modeling in the same manner described above for the proposed project. Trip generation rates for the school (ITE Land Use Code 534 – Private K-8 School) were provided by the applicant’s traffic consultant and used to estimate existing condition mobile source emissions.25 Construction Emissions GHG emissions associated with construction were computed to be 607 MT of CO2e for the total construction period (2022-2024), with the highest annual GHG emissions estimate being 422 MT 24 Association of Environmental Professionals, 2016.

These computations assume the project is constructed during the shortest time period. These are the emissions from on-site operation of construction equipment, vendor and hauling truck trips, and worker trips. Neither the County nor BAAQMD have an adopted threshold of significance for construction related GHG emissions, though BAAQMD recommends quantifying emissions and disclosing that GHG emissions would occur during construction. BAAQMD also encourages the incorporation of best management practices to reduce GHG emissions during construction where feasible and applicable. Operational Emissions The CalEEMod model, along with the project vehicle trip generation rates, was used to estimate daily emissions associated with operation of the fully developed site under the proposed project. As shown in Table 7, the net annual emissions resulting from operation of the proposed project are predicted to be reduction of 300 MT of CO2e in 2024. As shown in Table 7, the project would not exceed the 660 MT CO2e/year bright-line threshold in 2024. Table 7.

No Impact: Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases? The proposed project would not conflict or otherwise interfere with the statewide GHG reduction measures identified in CARB’s Scoping Plan. For example, proposed buildings would be constructed in conformance with CALGreen and the Title 24 Building Code, which requires high- efficiency water fixtures and water-efficient irrigation systems. Additionally, by completing Contra Costa’s Development Checklist (see Attachment 7), the project would demonstrate compliance with the county’s CAP and applicable GHG emissions reduction goals. The project would also be subject to local policies that may affect GHG emissions. Conclusions The proposed project would result in lower GHG emissions when compared to the school that was occupying the site. Thus, the project would have a GHG emissions benefit when compared to the school. Additionally, the project would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing GHG emissions. 31 Supporting Documentation Attachment 1 is the methodology used to compute community risk impacts, including the methods to compute lifetime cancer risk from exposure to project emissions.

Attachment 7 includes the Contra Costa CAP’s Development Checklist. Attachment 1: Health Risk Calculation Methodology A health risk assessment (HRA) for exposure to Toxic Air Contaminates (TACs) requires the application of a risk characterization model to the results from the air dispersion model to estimate potential health risk at each sensitive receptor location. The State of California Office of Environmental Health Hazard Assessment (OEHHA) and California Air Resources Board (CARB) develop recommended methods for conducting health risk assessments. The most recent OEHHA risk assessment guidelines were published in February of 2015.26 These guidelines incorporate substantial changes designed to provide for enhanced protection of children, as required by State law, compared to previous published risk assessment guidelines. CARB has provided additional guidance on implementing OEHHA’s recommended methods.27 This HRA used the 2015 OEHHA risk assessment guidelines and CARB guidance. The BAAQMD has adopted recommended procedures for applying the newest OEHHA guidelines as part of Regulation 2, Rule 5: New Source Review of Toxic Air Contaminants.28 Exposure parameters from the OEHHA guidelines and the recent BAAQMD HRA Guidelines were used in this evaluation. Cancer Risk Potential increased cancer risk from inhalation of TACs is calculated based on the TAC concentration over the period of exposure, inhalation dose, the TAC cancer potency factor, and an age sensitivity factor to reflect the greater sensitivity of infants and children to cancer causing TACs. The inhalation dose depends on a person’s breathing rate, exposure time and frequency and duration of exposure. These parameters vary depending on the age, or age range, of the persons being exposed and whether the exposure is considered to occur at a residential location or other sensitive receptor location. The current OEHHA guidance recommends that cancer risk be calculated by age groups to account for different breathing rates and sensitivity to TACs. Specifically, they recommend evaluating risks for the third trimester of pregnancy to age zero, ages zero to less than two (infant exposure), ages two to less than 16 (child exposure), and ages 16 to 70 (adult exposure). Age sensitivity factors (ASFs) associated with the different types of exposure are an ASF of 10 for the third trimester and infant exposures, an ASF of 3 for a child exposure, and an ASF of 1 for an adult exposure. Also associated with each exposure type are different breathing rates, expressed as liters per kilogram of body weight per day (L/kg-day) or liters per kilogram of body weight per 8-hour period for the case of worker or school child exposures. As recommended by the BAAQMD for residential exposures, 95th percentile breathing rates are used for the third trimester and infant exposures, and 80th percentile breathing rates for child and adult exposures. For children at schools and daycare facilities, BAAQMD recommends using the 95th percentile 8-hour breathing rates. Additionally, CARB and the BAAQMD recommend the use of a residential exposure duration of 30 years for sources with long-term emissions (e.g., roadways). For workers, assumed to be adults, 26 OEHHA, 2015.

December 2016. a 25-year exposure period is recommended by the BAAQMD. For school children a 9-year exposure period is recommended by the BAAQMD. Under previous OEHHA and BAAQMD HRA guidance, residential receptors are assumed to be at their home 24 hours a day, or 100 percent of the time. In the 2015 Risk Assessment Guidance, OEHHA includes adjustments to exposure duration to account for the fraction of time at home (FAH), which can be less than 100 percent of the time, based on updated population and activity statistics. The FAH factors are age-specific and are: 0.85 for third trimester of pregnancy to less than 2 years old, 0.72 for ages 2 to less than 16 years, and 0.73 for ages 16 to 70 years. Use of the FAH factors is allowed by the BAAQMD if there are no schools in the project vicinity have a cancer risk of one in a million or greater assuming 100 percent exposure (FAH = 1.0). Functionally, cancer risk is calculated using the following parameters and formulas: Cancer Risk (per million) = CPF x Inhalation Dose x ASF x ED/AT x FAH x 106 Where: CPF = Cancer potency factor (mg/kg-day)-1 ASF = Age sensitivity factor for specified age group ED = Exposure duration (years) AT = Averaging time for lifetime cancer risk (years) FAH = Fraction of time spent at home (unitless) Inhalation Dose = Cair x DBR* x A x (EF/365) x 10-6 Where: Cair = concentration in air (μg/m3) DBR = daily breathing rate (L/kg body weight-day) 8HrBR = 8-hour breathing rate (L/kg body weight-8 hours) A = Inhalation absorption factor EF = Exposure frequency (days/year) 10-6 = Conversion factor * An 8-hour breathing rate (8HrBR) is used for worker and school child exposures. The health risk parameters used in this evaluation are summarized as follows: Exposure Type  Infant Child Adult Parameter Age Range  3rd Trimester 0<2 2 < 16 16 - 30 DPM Cancer Potency Factor (mg/kg-day)-1 1.10E+00 1.10E+00 1.10E+00 1.10E+00 Daily Breathing Rate (L/kg-day) 80th Percentile Rate 273 758 572 261 Daily Breathing Rate (L/kg-day) 95th Percentile Rate 361 1,090 745 335 8-hour Breathing Rate (L/kg-8 hours) 95th Percentile Rate - 1,200 520 240 Inhalation Absorption Factor 1 1 1 1 Averaging Time (years) 70 70 70 70 Exposure Duration (years) 0.25 2 14 14* Exposure Frequency (days/year) 350 350 350 350* Age Sensitivity Factor 10 10 3 1 Fraction of Time at Home (FAH) 0.85-1.0 0.85-1.0 0.72-1.0 0.73* Non-Cancer Hazards Non-cancer health risk is usually determined by comparing the predicted level of exposure to a chemical to the level of exposure that is not expected to cause any adverse effects (reference exposure level), even to the most susceptible people. Potential non-cancer health hazards from TAC exposure are expressed in terms of a hazard index (HI), which is the ratio of the TAC concentration to a reference exposure level (REL). OEHHA has defined acceptable concentration levels for contaminants that pose non-cancer health hazards. TAC concentrations below the REL are not expected to cause adverse health impacts, even for sensitive individuals. The total HI is calculated as the sum of the HIs for each TAC evaluated and the total HI is compared to the BAAQMD significance thresholds to determine whether a significant non-cancer health impact from a project would occur. Typically, for residential projects located near roadways with substantial TAC emissions, the primary TAC of concern with non-cancer health effects is diesel particulate matter (DPM). For DPM, the chronic inhalation REL is 5 micrograms per cubic meter (μg/m3). Annual PM2.5 Concentrations While not a TAC, fine particulate matter (PM2.5) has been identified by the BAAQMD as a pollutant with potential non-cancer health effects that should be included when evaluating potential community health impacts under the California Environmental Quality Act (CEQA). The thresholds of significance for PM2.5 (project level and cumulative) are in terms of an increase in the annual average concentration. When considering PM2.5 impacts, the contribution from all sources of PM2.5 emissions should be included. For projects with potential impacts from nearby local roadways, the PM2.5 impacts should include those from vehicle exhaust emissions, PM2.5 generated from vehicle tire and brake wear, and fugitive emissions from re-suspended dust on the roads.

B2-8 Oak Road Solar Calculation According to project information provided by the project applicant, each dwelling unit would include solar panel electricity generation in compliance with the California Building Code. According to the California Code of Regulations, Title 24, Part 6, Subchapter 8 – Low-Rise Residential Building – Performance and Prescriptive Compliance Approaches, “[a]ll low-rise residential buildings shall have a photovoltaic (PV) system meeting the minimum qualification requirements as specified in Joint Appendix JA11, with annual electrical output equal or greater than the dwelling’s annual electrical usage as determined by Equation 150.1-C:” Equation 150.1-C Annual Photovoltaic Electrical Output kWPV = (CFA x A)/1,000 + (NDwell x B) Where: kWPV = kWdc size of the PV system CFA = conditioned floor area NDwell = number of dwelling units A = Adjustment factor from Table 150.1-C B = Dwelling adjustment factor from Table 150.1-C As the project is located in climate zone 12, the A adjustment factor mentioned above is identified as 0.613 and the B adjustment factor mentioned above is identified as 1.40. The conditioned floor area is drawn from the project site plans. Therefore: kWPV = (292,965 x 0.613)/1,000 + (125 x 1.40) = 354.59 While this accounts for the entire project’s kW PV system, it does not provide the annual production rate that would be generated by this size of system. Therefore, the total kW PV system was reduced to a per-dwelling-unit kW PV system to determine the expected annual production rate. 354.59 kW PV divided by 125 dwelling units results in an average 2.84 kW PV system per dwelling unit. According to TheEcoExperts.com,1 a 3-kW PV system has an average annual production rate of 2,550 kWh/year. The below equation proportionally applies the same average annual production rate to the calculated 2.84-kW system per each dwelling unit. (2.84/3) * 2,550 kWh/year = 2,411 kWh/year Therefore, the proposed project is expected to result in an average on-site electricity generation rate of 2,411 kWh per dwelling unit per year. The following equation converts this to total annual on-site electricity generation. Therefore: 2,411 kWh/year * 125 Residences = 301,399 kWh/year 1 TheEcoExperts. 2016. “Solar Panel Output.” Website: http://www.theecoexperts.com/solar-panel-output/. Accessed June 9, 2021.

The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly aected by activities in the project area. However, determining the likelihood and extent of eects a project may have on trust resources typically requires gathering additional site-specic (e.g., vegetation/species surveys) and project-specic (e.g., magnitude and timing of proposed activities) information. Below is a summary of the project information you provided and contact information for the USFWS oce(s) with jurisdiction in the dened project area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional information applicable to the trust resources addressed in that section.

The primary information used to generate this list is the known or expected range of each species. Additional areas of inuence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly aected by activities in that area (e.g., placing a dam upstream of a sh population even if that sh does not occur at the dam site, may indirectly impact the species by reducing or eliminating water ow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential eects to species, additional site-specic and project-specic information is often required. Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local oce and a species list which fullls this requirement can only be obtained by requesting an ocial species list from either the Regulatory Review section in IPaC (see directions below) or from the local eld oce directly. For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an ocial species list by doing the following: 1. Draw the project location and click CONTINUE. 2. Click DEFINE PROJECT. 3. Log in (if directed to do so). 4. Provide a name and description for your project. 5. Click REQUEST SPECIES LIST. Listed species and their critical habitats are managed by the Ecological Services Program of the U.S. Fish and Wildlife Service (USFWS) and the sheries division of the National Oceanic and Atmospheric Administration (NOAA Fisheries ). Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown on this list. Please contact NOAA Fisheries for species under their jurisdiction. 1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also shows species that are candidates, or proposed, for listing. See the listing status page for more information.

This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this report. Probability of Presence () Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey eort (see below) can be used to establish a level of condence in the presence score. One can have higher condence in the presence score if the corresponding survey eort is also high. How is the probability of presence score calculated? The calculation is done in three steps: 1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that Oak Titmouse Baeolophus inornatus This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. https://ecos.fws.gov/ecp/species/9656 Breeds Mar 15 to Jul 15 Rufous Hummingbird selasphorus rufus This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. https://ecos.fws.gov/ecp/species/8002 Breeds elsewhere Song Sparrow Melospiza melodia This is a Bird of Conservation Concern (BCC) only in particular Bird Conservation Regions (BCRs) in the continental USA Breeds Feb 20 to Sep 5 Spotted Towhee Pipilo maculatus clementae This is a Bird of Conservation Concern (BCC) only in particular Bird Conservation Regions (BCRs) in the continental USA https://ecos.fws.gov/ecp/species/4243 Breeds Apr 15 to Jul 20 Tricolored Blackbird Agelaius tricolor This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. https://ecos.fws.gov/ecp/species/3910 Breeds Mar 15 to Aug 10 Wrentit Chamaea fasciata This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska.

For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. 2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score. To see a bar's probability of presence score, simply hover your mouse cursor over the bar. Breeding Season () Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Eort () Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. To see a bar's survey eort range, simply hover your mouse cursor over the bar. No Data () A week is marked as having no data if there were no survey events for that week. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas o the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds. Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site. What does IPaC use to generate the migratory birds potentially occurring in my specied location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location. 5/26/2021 IPaC: Explore Location resources https://ecos.fws.gov/ipac/location/YTU42H4LKVFONJNOJYOXJUGGKU/resources 12/14 The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and ltered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identied as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to oshore activities or development. Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool. What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specied location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets . Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specied. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacic Islands, Puerto Rico, and the Virgin Islands); 2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and 3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in oshore areas from certain types of development or activities (e.g. oshore energy development or longline shing). Although it is important to try to avoid and minimize impacts to all birds, eorts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially aected by oshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area o the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also oers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results les underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. 5/26/2021 IPaC: Explore Location resources https://ecos.fws.gov/ipac/location/YTU42H4LKVFONJNOJYOXJUGGKU/resources 13/14 Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring. What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specied location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey eort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey eort is the key component. If the survey eort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey eort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to conrm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be conrmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

Data limitations The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identied based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland boundaries or classication established through image analysis. The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth verication work conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping problems. Wetlands or other mapped features may have changed since the date of the imagery or eld work. There may be occasional dierences in polygon boundaries or classications between the information depicted on the map and the actual conditions on site. Data exclusions Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tubercid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. Data precautions Federal, state, and local regulatory agencies with jurisdiction over wetlands may dene and describe wetlands in a dierent manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to dene the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning specied agency regulatory programs and proprietary jurisdictions that may aect such activities.

THIS PAGE INTENTIONALLY LEFT BLANK Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR FirstCarbon Solutions C.3 - Special-status Species Assessment–Oak Road THIS PAGE INTENTIONALLY LEFT BLANK From:Katrina Krakow To:Torre, Marshall; Rick Hopkins Subject:Palmer-Walnut Creek Date:Wednesday, December 2, 2020 1:52:46 PM Attachments:image004.jpg image001.jpg Hello Marshall, As you know, I assessed the site for its potential to support special status plant and animal species and wetlands during the site visit on Friday, July 24, 2020. The site is an old school. There does not appear to be any issues related to special status plants and there does not appear to be any special status animal species issues that cannot be resolved by preconstruction surveys and construction-free buffers. Special status animal species are limited to several bird species as well as bat species. Below is a summary of potential constraints to the project. Bats (potential timing constraint): The buildings onsite are old and most of them have some potential to support roosting bat habitat, as they have access points into the buildings. Part of the brick buildings also have ceiling tiles which may act like an attic for habitat for roosting bats. The large trees of the site may support cavities or dense foliage for bats to roost in as well. As the current budget allowed for only an overview bat habitat assessment, a full bat assessment should be conducted prior to removing trees and buildings onsite to determine which features at the time closer to removal have the potential to support bats. Removal plans for features identified during the assessment should follow directions in the assessment, which may include one or more of the following: 1) preconstruction surveys for areas which can be visually surveyed, 2) night emergence surveys for those features which cannot be visually surveyed outside of the overwintering season (surveys during March 1-October 15), and 3) timing restrictions for removal outside the overwintering and maternity seasons (typically removal can occur with a two-step removal process during March 1-April 15 and August 31-October 15). As the site is currently developed, loss of this habitat would not result in a significant affect. In addition, preconstruction surveys and other appropriate minimization measures will be in place to reduce impacts to less-than-significant for nesting birds. Nesting Migratory Birds and Raptors (potential timing constraint): Nesting migratory birds and raptors, including potential special status species, may nest on the site. There are several very large trees, moderately sized trees, shrubs, and ground habitat where nests may occur. Therefore, preconstruction surveys would need to be conducted should construction plan to start in the nesting season (February 1-August 31). No surveys for nesting birds would be required outside of those dates. As the site is currently developed, loss of this habitat would not result in a significant affect. In addition, preconstruction surveys and other appropriate minimization measures will be in place to reduce impacts to less-than-significant for nesting birds. Trees (potential design and permit constraint): Contra Costa County has a tree ordinance that covers several trees onsite which will require a permit to remove. There are several oak trees as well as other species of trees which would be covered under this ordinance. As I know you have an arborist on board already, I will defer to him. Please also note that: The property is not located within wetlands as defined by the United States Fish and Wildlife Service Manual, Part 660 FW2 (June 21, 1993).

Live Oak Associates, Inc. (LOA)’s initial reports to SummerHill Homes were designed as due diligence-level reports. We have included below the special status species occurrence table and relevant mitigations as requested. Special Status Plants and Animals. Several species of plants and animals within the state of California have low populations, limited distributions, or both. Such species may be considered “rare” and are vulnerable to extirpation as the state’s human population grows and the habitats these species occupy are converted to agricultural and urban uses. State and federal laws have provided the California Department of Fish and Wildlife (CDFW) and the U.S. Fish and Wildlife Service (USFWS) with a mechanism for conserving and protecting the diversity of plant and animal species native to the state. A sizable number of native plants and animals have been formally designated as threatened or endangered under state and federal endangered species legislation. Others have been designated as “candidates” for such listing. Still others have been designated as “species of special concern” by the CDFW. The California Native Plant Society (CNPS) has developed its own set of lists of native plants considered rare, threatened, or endangered (CNPS 2021). Collectively, these plants and animals are referred to as “special status species.” A number of special status plants and animals occur in the vicinity of the project site. These species, and their potential to occur in the project site, are listed in Table 1. Sources of information for this table included California Natural Diversity Data Base (CDFW 2020), Listed Plants and Listed Animals (USFWS 2020), State and Federally Listed Endangered and Threatened Animals of California (CDFW 2020), The California Native Plant Society’s 2 Inventory of Rare and Endangered Vascular Plants of California (CNPS 2020), California Bird Species of Special Concern (Shuford and Gardall 2008), and California Amphibian and Reptile Species of Special Concern (Thompson et al. 2016). This information was used to evaluate the potential for special status plant and animal species that occur on the site. Prior to the site visit, a search of published accounts for all of the relevant special status plant and animal species was conducted for the Walnut Creek USGS 7.5 minute quadrangle in which the project site occurs, and for the eight surrounding quadrangles (Benicia, Vine Hill, Honker Bay, Briones Valley, Clayton, Oakland East, Las Trampas Ridge, and Diablo) using the CNDDB Rarefind5. All species listed as occurring in these quadrangles on CNPS Lists 1A, 1B, 2, or 4 were also reviewed. As the site is a fully developed and highly impacted site, all special status plants that occur or once occurred within the project vicinity are considered absent from the site. As the site lacks aquatic habitat such as streams, creeks, ponds, and vernal pools, fairy shrimp and fish are considered absent from the site. We have also excluded from our analysis those species for which the site is not within their home range and for which suitable habitat such as bay lands, marshlands, riparian, and serpentine habitat does not occur onsite. Below is our assessment of the potential of species which may be reasonably expected to occur within the project vicinity to occur on the site. TABLE 1. LIST OF SPECIAL STATUS SPECIES THAT COULD OCCUR IN THE PROJECT VICINITY ANIMALS (Continued adapted from CDFW 2020 and USFWS 2020) Species Listed as Threatened or Endangered under the State and/or Federal Endangered Species Act Species Status Habitat Occurrence in the Project Site California Tiger Salamander (CTS) (Ambystoma californiense) FT, CT Breeds in vernal pools and stock ponds of central California; adults aestivate in grassland habitats adjacent to the breeding sites. Absent. Suitable breeding and upland habitat for this species is absent from the site and the vicinity of the site. The nearest suitable habitat and recorded observation approximately 0.6 miles to the southeast of the site (CDFW 2020) and separated from the site by substantial development that would act as a landscape barrier for the CTS. Foothill yellow-legged frog (FYLF) (Rana boylii) CE, CSC Occurs in swiftly flowing streams and rivers with rocky substrate with open, sunny banks in forest, chaparral, and woodland habitats, and can sometimes be found in isolated pools. Absent. Suitable aquatic and upland habitat for the FYLF is absent from the project site and the vicinity of the site. California Red-legged Frog (CRLF) (Rana aurora draytonii) FT, CSC Rivers, creeks and stock ponds of the Sierra foothills and Bay Area, preferring pools with overhanging vegetation. Absent. Suitable aquatic and upland habitat for the CRLF is absent from the project site and the vicinity of the site. 3 TABLE 1. LIST OF SPECIAL STATUS SPECIES THAT COULD OCCUR IN THE PROJECT VICINITY ANIMALS (Continued adapted from CDFW 2020 and USFWS 2020) Species Listed as Threatened or Endangered under the State and/or Federal Endangered Species Act Species Status Habitat Occurrence in the Project Site Alameda Whipsnake (Masticophis lateralis euryxanthus) FT, CT Occurs in chaparral foothills, shrublands with scattered grass patches, rocky canyons, and watercourses. Occurs in the San Francisco Bay area including Alameda, Contra Costa, Santa Clara and San Joaquin Counties, CA. Absent. The site is fully developed and suitable habitat for this species is absent from the site. California least tern (Sterna antillarum browni) FE, CE, CP Occurs in central to southern California April to November. Found in and near coastal habitat including coasts, beaches, bays, estuaries, lagoons, lakes, and rivers. Absent. Although this species may fly over the site during migration, it is not expected to forage or roost on the site. Tricolored Blackbird (Agelaius tricolor) CT, CSC Breeds near fresh water in dense emergent vegetation. Absent. Suitable nesting habitat is absent from the project site. Swainson’s hawk (SWHA) (Buteo swainsoni) CT Breeds in stands with few trees in juniper-sage flats, riparian areas, and in oak savannah. Requires adjacent suitable foraging areas such as grasslands or alfalfa fields supporting rodent populations. Absent. The SWHA is not known to breed in this area; the nearest record is more than seven miles to the east of the project site and is a record from 1898. Therefore, Swainson’s hawks are presumed to be absent from the site. ANIMALS (adapted from CDFW 2020 and USFWS 2020) State Species of Special Concern and Protected Species Species Status Habitat Occurrence in the Project Site Northern California legless lizard (Anniella pulchra) CSC The NCLL (previously called black legless lizard) occurs mostly underground in warm moist areas with loose soil and substrate. The NCLL occurs in habitats including sparsely vegetated areas of beach dunes, chaparral, pine-oak woodlands, desert scrub, sandy washes, and stream terraces with sycamores, cottonwoods, or oaks. Absent. Habitats required by northern California legless lizards are absent from the site, as the site lacks sandy soils. Coast horned lizard (Phrynosoma blainvillii) CSC Occurs in grasslands, scrublands, oak woodlands, etc. of central California. Common in sandy washes with scattered shrubs. Absent. Habitats required by coast horned lizards are absent from the site as the site lacks sandy soils. 4 TABLE 1. LIST OF SPECIAL STATUS SPECIES THAT COULD OCCUR IN THE PROJECT VICINITY ANIMALS (Continued adapted from CDFW 2020 and USFWS 2020) State Species of Special Concern and Protected Species Species Status Habitat Occurrence in the Project Site Western pond turtle (WPT) (Actinemys marmorata) CSC Intermittent and permanent waterways including streams, marshes, rivers, ponds and lakes. Open slow- moving water of rivers and creeks of central California with rocks and logs for basking. Absent. Water features are absent from the site and the vicinity of the site. Northern harrier (Circus cyaneus) CSC Frequents meadows, grasslands, open rangelands, freshwater emergent wetlands; uncommon in wooded habitats. Unlikely. Habitat onsite for the northern harrier is poor and it would be unlikely to forage or nest on the site. White-tailed Kite (WTK) (Elanus leucurus) CP Open grasslands and agricultural areas throughout central California. Possible. Several large trees of the site are suitable to support nesting WTK. American peregrine falcon (Falco peregrines anatum) CP Individuals breed on cliffs in the Sierra or in coastal habitats; occurs in many habitats of the state during migration and winter. Unlikely. The CNDDB reports the location for this species on the quadrangle scale, however, suitable nesting habitat such as tall buildings is not present on the site. Golden Eagle (GE) (Aquila chrysaetos) CP Typically frequents rolling foothills, mountain areas, sage-juniper flats and desert. Absent. Suitable foraging and breeding habitat for the golden eagle is absent from the site. Bald eagle (Haliaeetus leucocephalus) CE, CP Breeding habitat is usually within 4 km of a water source in a tall tree or cliffs; roosting in large numbers in winter is common. Absent. Suitable foraging and breeding habitat for the bald eagle is absent from the site. Burrowing Owl (BUOW) (Athene cunicularia) CSC Found in open, dry grasslands, deserts and ruderal areas. Requires suitable burrows. This species is often associated with California ground squirrels. Unlikely. Suitable habitat in the form of open land with burrows is absent from the site, therefore, burrowing owls would be unlikely to occur on the site. Short-eared owl (Asio flammeus) CSC Occur in wide open spaces including marshes, open shrublands, grassland, prairie, and agricultural field habitats, and need dense ground cover to conceal nests. Absent. Suitable habitat I the form of open land is largely absent from the site and the sports fields provide poor quality habitat for the short-eared owl. California Yellow Warbler (Dendroica petechia brewsteri) CSC Migrants move through many habitats of Sierra and its foothills. This species breeds in riparian thickets of alder, willow and cottonwoods. Unlikely. Although suitable breeding habitat is absent from the site, this species may be expected to migrate through the site from time to time. Townsend’s Big-eared bat (Corynorhinus townsendii) CSC Primarily a cave-dwelling bat that may also roost in buildings. Occurs in a variety of habitats. Possible. Suitable foraging and roosting habitat occurs onsite in the form of buildings and trees of the site (CDFW 2020). 5 TABLE 1. LIST OF SPECIAL STATUS SPECIES THAT COULD OCCUR IN THE PROJECT VICINITY ANIMALS (Continued adapted from CDFW 2020 and USFWS 2020) State Species of Special Concern and Protected Species Species Status Habitat Occurrence in the Project Site Pallid Bat (Antrozous pallidus) CSC Grasslands, chaparral, woodlands, and forests; most common in dry rocky open areas providing roosting opportunities. Possible. Suitable foraging and roosting habitat occurs onsite in the form of buildings and trees of the site (CDFW 2020). Big free-tailed bat (Nyctinomops macrotis) CSC Migrant bats using elevations from 0-2600 meters. Roosts in rock crevices cliffs as well as in buildings, caves, and tree cavities. Possible. Suitable foraging and roosting habitat occurs onsite in the form of buildings and trees of the site (CDFW 2020). San Francisco Dusky-Footed Woodrat (Neotoma fuscipes annectens) CSC Found in hardwood forests, oak riparian and shrub habitats. Unlikely. Woodrat nests were not observed during the site visit and would have been observable if they occurred on the project site. Therefore, they are not likely to occur onsite. American Badger (Taxidea taxus) CSC Found in drier open stages of most shrub, forest and herbaceous habitats with friable soils, specifically grassland environments. Natal dens occur on slopes. Absent. Badgers are known to occur in the foothills, however, as the site is an infill site which is already developed, badgers are not expected to occur on the site. *Explanation of Occurrence Designations and Status Codes Present: Species observed on the site at time of field surveys or during recent past. Likely: Species not observed on the site, but it may reasonably be expected to occur there on a regular basis. Possible: Species not observed on the site, but it could occur there from time to time. Unlikely: Species not observed on the site, and would not be expected to occur there except, perhaps, as a transient. Absent: Species not observed on the site and precluded from occurring there because habitat requirements not met. STATUS CODES FE Federally Endangered CE California Endangered FT Federally Threatened CT California Threatened FPE Federally Endangered (Proposed) CR California Rare FC Federal Candidate CP California Protected CSC California Species of Special Concern CCE California Candidate Endangered CNPS California Native Plant Society Listing 1A Plants Presumed Extinct in California 3 Plants about which we need more 1B Plants Rare, Threatened, or Endangered in information – a review list California and elsewhere 4 Plants of limited distribution – a watch list 2 Plants Rare, Threatened, or Endangered in California, but more common elsewhere Potential Impacts and Mitigation Measures. Of the 23 species which have some potential to occur or to have once occurred on the project site or the vicinity of the project site, all except for four are considered to be absent or unlikely to occur onsite. Of the four species with a higher potential to occur onsite, three are bat species (Townsend’s big-eared bat, pallid bat, and big free-tailed bat) which have the potential to forage over the site and roost in the buildings and trees of the site and one is a bird species (white-tailed kite) which has the potential to nest in the large trees of the site and forage throughout the site. Site demolition and redevelopment of the site has will not cause a significant negative effect to these species, however, these activities do have the potential to cause harm or to injure individuals of these species, therefore, appropriate mitigation measures for these species as well as other nesting migratory birds and raptors are below. 6 Bats (potential timing constraint): The buildings onsite are old and most of them have some potential to support roosting bat habitat, as they have access points into the buildings. Part of the brick buildings also have ceiling tiles which may act like an attic for habitat for roosting bats. The large trees of the site may support cavities or dense foliage for bats to roost in as well. As the current budget allowed for only an overview bat habitat assessment, a full bat assessment should be conducted prior to removing trees and buildings onsite to determine which features at the time closer to removal have the potential to support bats. Removal plans for features identified during the assessment should follow directions in the assessment, which may include one or more of the following: 1) preconstruction surveys for areas which can be visually surveyed, 2) night emergence surveys for those features which cannot be visually surveyed outside of the overwintering season (surveys during March 1-October 15), and 3) timing restrictions for removal outside the overwintering and maternity seasons (typically removal can occur with a two-step removal process during March 1-April 15 and August 31-October 15). Nesting Migratory Birds and Raptors Including the White-Tailed Kite (potential timing constraint): Nesting migratory birds and raptors, including the white-tailed kite, may nest on the site. There are several very large trees, moderately sided trees, shrubs, and ground habitat where nests may occur. Therefore, preconstruction surveys would need to be conducted should construction plan to start in the nesting season (February 1-August 31). No surveys for nesting birds would be required outside of those dates. Sincerely, Katrina Krakow, M.S.

A number of structures are present on the site as well as paved driveway and landscaping. HortScience | Bartlett Consulting, divisions of the F.A. Bartlett Tree Expert Co., was asked to prepare a Tree Report for the project. Contra Costa County requires that a Tree Report be prepared in situations where development and construction activity will occur near existing trees and/or if numerous trees are involved. This report provides the following information: 1. A survey of trees currently growing on the site. 2. An assessment of the impacts of constructing the proposed project on the trees based on the proposed site plan prepared by RJA (project engineers). 3. Recommendations for action. 4. Guidelines for tree preservation during the design, construction and maintenance phases of development. Assessment Methods Trees #76 – 84 were assessed in July 2020; trees #101 – 172 in December 2020. The scope encompassed all trees over 6” in diameter located within the proposed project limits. The assessment procedure consisted of the following steps: 1. Identify the tree as to species. 2. Attach a numerically coded metal tag to the trunk of each tree. Tree tag numbers were not continuous. 3. Record the tree’s location on a map. 4. Measure the trunk diameter at a point 54” above grade. 5. Evaluate the health and structural condition using a scale of 0 – 5 where 0 = dead, 1 = poor and 5 = excellent condition. 5. Comment on presence of defects in structure, insects or diseases and other aspects of development. 6. Assess the tree’s suitability for preservation as low, moderate or high. Trees #80, 160, 161, 168, 171 and 172 appeared to be located on adjacent properties. These trees were included in the assessment because tree trunks were within 2 ft. of the presumed property line and/or tree crowns extended into the project area. Results for individual trees are located in the Tree Assessment Form (see Attachments). Tree locations are noted by tree tag number in the Tree Assessment Plan. Tree Report. January 4, 2021. HortScience | Bartlett Consulting Oak Road Townhome Condominiums. SummerHill Homes. Page 2 Description of Trees Eighty-one (81) trees were assessed representing 22 species. Valley oak and Calif. bay are native to Contra Costa County. While the bay trees appeared to be planted, the valley oaks were likely indigenous to the site. The remaining 19 species were typical of those found in landscape plantings in the County with the exception white ash which is somewhat unusual. Table 1. Tree condition & frequency of occurrence.

Most were located in the southern portion of the site including 19 trees that formed a long screen along the south property line (Photo 1). Redwoods #164 to 167 were in the northwest corner of the site, near Jones Rd. Trees were semi-mature in development with trunk diameters between 12 and 31 in. Approximately 50% of redwoods were 22 in. or larger. Tree condition was generally good (19 trees). Redwoods #157, 164, 165, 166, and 167 were in excellent condition. Tree #113 was in poor condition and #114 and 115 were fair. Tree Report. January 4, 2021. HortScience | Bartlett Consulting Oak Road Townhome Condominiums. SummerHill Homes. Page 3 Photo 1 (left). A row of coast redwoods was present on the south side of the site. Photo 2 (above). Several mature valley oaks included trees #81 (right) and 82 (left) Nine valley oaks were present, scattered across the north half of the site (Photo 2). Trees varied from semi-mature to mature in development with trunk diameters ranging from 13 to 73 in. Tree condition was variable. Valley oaks #79 and 84 were fair; trees #76, 77, 78, 80, 81, and 82 were good; tree #83 was excellent. Tree form ranged from rounded to asymmetric in response to growing conditions and crowding. Tree #77 was 73 in. in diameter (Photo 3). This large tree was near Oak Road. It has a wide- spreading crown. Several large scaffold limbs arose at 12 ft. One of these extended to the southwest. Cavities in the lower trunk had been filled with concrete many years ago. Photo 3. Looking northwest at valley oak #77. Valley oak #80 was located off the project site to the north. Its crown, however, extended over the property line by approximately 35 ft. The crown was asymmetric and heavy to the south. Branches on the north had been removed and reduced. Eight glossy privets were scattered throughout the site. Most were typical small trees with multiple stems that arose low on the trunk. Tree condition was compromised by poor health, likely due to a lack of supplemental irrigation. Trunk diameters ranged from 6 to 10 in. Tree Report. January 4, 2021. HortScience | Bartlett Consulting Oak Road Townhome Condominiums. SummerHill Homes. Page 4 Five scarlet oaks (#101 to 105) were street trees along Oak Road (Photo 4). Trees had been installed in cutouts in the sidewalk. Unfortunately, overhead electrical conductors were present, and trees had been topped to maintain clearance. As a result, scarlet oaks had poor structure and were in poor condition. Trunk diameters ranged from 10 to 15 in. Photo 4. Looking north at scarlet oak trees. Note presence of overhead electrical lines. Five mulberries were present (Photo 5). All had been topped/cut back to 6 to 8 ft. tall stumps. As a result, all were in poor condition. Trunk diameters varied from 12 to 20 in. Photo 5. Typical mulberry in a pavement cutout. No other species was represented by more than three trees. Included in that group were:  Almond #108 had two trunks of 5 in. The tree was in poor condition with poor form and structure.  Apple #110 was 9 in. and in poor condition due to a history of topping.  Calif. bays #154, 155, 156 were large shrub-like plants. All were in fair condition with dense canopies of foliage and multiple stems arising at ground level.  Cherry #111 was 5 in. and in fair condition.  Deodar cedar #168 was located off-site in the northwest corner of the project. It was approximately 23 in. in diameter and in excellent condition.  English walnuts #162 and 163 were mature trees in the northwest corner of the site. Both were in poor condition.  Fig #121 had stems of 13 and 10 in. It was in fair condition and had been topped to 15 ft. Tree Report. January 4, 2021.

Page 6 Suitability for Preservation Trees that are preserved on development sites must be carefully selected to make sure that they may survive development impacts, adapt to a new environment and perform well in the landscape. Our goal is to identify trees that have the potential for long-term health, structural stability and longevity. Evaluation of suitability for preservation considers several factors:  Tree health Healthy, vigorous trees are better able to tolerate impacts such as root injury, demolition of existing structures, changes in soil grade and moisture, and soil compaction than are non-vigorous trees.  Structural integrity Trees with significant amounts of wood decay and other structural defects that cannot be corrected are likely to fail. Such trees should not be preserved in areas where damage to people or property is likely.  Species response There is a wide variation in the response of individual species to construction impacts and changes in the environment. In our experience, for example, Monterey pine, Calif. bay, and blue gum are very sensitive to construction impacts; while coast live oak is more tolerant of site disturbance.  Tree age and longevity Old trees, while having significant emotional and aesthetic appeal, have limited physiological capacity to adjust to an altered environment. Young trees are better able to generate new tissue and respond to change.  Species invasiveness Species which spread across a site and displace desired vegetation are not always appropriate for retention. This is particularly true when indigenous species are displaced. The California Invasive Plant Inventory Database (www.cal-ipc.org) lists species identified as being invasive. Contra Costa County is part of the Central West Floristic Province. Species identified as invasive that were present at Oak Road Townhome Condominiums include tree of heaven and Mexican fan palm. Tree condition (health and structure) is the starting point for assessing suitability for preservation. In addition, suitability for preservation considers species response to impacts and invasiveness. Each tree was rated for suitability for preservation based upon its age, health, structural condition and ability to safely coexist within a development environment (Table 2). Tree Report. January 4, 2021. HortScience | Bartlett Consulting Oak Road Townhome Condominiums. SummerHill Homes. Page 7 Table 2. Tree suitability for preservation. Oak Road Townhome Condominiums. Contra Costa County CA. High Trees in good condition that have the potential for longevity at the site. Twenty-eight (28) trees were rated as having high suitability for preservation including 22 coast redwoods; valley oak #76, 80, 82, 83; Deodar cedar #168, and persimmon #145. Moderate Trees in fair health and/or possessing structural defects that may be abated with treatment. Trees in this category require more intense management and monitoring, and may have shorter life-spans than those in the “high” category. Eleven (11) trees were rated as having moderate suitability for preservation: valley oak #77, 78, 79, 81, 84; coast redwood #115, 139, 140; and southern magnolia #119, 120, 121. Low Trees in poor health or possessing significant defects in structure that cannot be abated with treatment. These trees can be expected to decline regardless of management. The species or individual tree may possess either characteristics that are undesirable in landscape settings or be unsuited for use areas. Forty-two (42) trees were rated as having low suitability for preservation including: 8 glossy privet, 5 mulberry, and 5 scarlet oak. We consider trees with high suitability for preservation to be the best candidates for preservation. We do not normally recommend retention of trees with low suitability for preservation in areas where people or property will be present. Retention of trees with moderate suitability for preservation depends upon the intensity of proposed site changes. Evaluation of Impacts and Recommendations for Action Appropriate tree retention develops a practical match between the location and intensity of construction activities and the quality and health of trees. The tree assessment was the reference points for tree condition and quality. Impacts from the proposed project were assessed using the preliminary site plan prepared by RJA Associates, project engineers, as well as detail of preliminary grading and utility plans near valley oak #77. The project plans to construct 125 units, up to three stories tall with some roof decks. Entry roads will be installed from both Oak and Jones Roads. Impacts to trees could occur in a variety of ways. First, demolition of existing improvements such as buildings and infrastructure may directly damage tree roots and crowns. As significantly, grading and other construction activities may also damage trees, through both direct mechanical injury and indirectly by altering drainage. Given the density of site development, all on- site trees are located within areas proposed for development. Tree Report. January 4, 2021. HortScience | Bartlett Consulting Oak Road Townhome Condominiums. SummerHill Homes. Page 8 Contra Costa Code (section 816-6.8010) identifies factors that may be taken into account when making a decision to approve or deny a tree removal permit application. Among the factors are: (A) Tree is in poor health and cannot be saved. Twenty-seven (27) of the 81 trees assessed were in poor condition. (G) Reasonable development of the property would require the alteration or removal of the tree and this development could not be reasonably accommodated on another area of the lot. The proposed project involves construction of 125 residential units as well as associated infrastructure and parking. The project will impact the site from property line to property. Impacts to all on-site trees will be severe as all trees are within areas proposed for development. Based on my review of project plans and assessment of existing trees, I recommend removal of 74 on-site trees, relocation of valley oak #83, and preservation of six off-site trees (Table 3). As an example of the extent of impacts, valley oak #77 is a 73 in. diameter tree in good condition. It is located at a planned street corner near the entry from Oak Road. The street surface would be approximately 1 ft. above existing grade. Curb and gutter would be installed 10 ft. from the trunk on two sides. Both pavement and curb would require excavation. In addition, utilities would be installed under both streets. Utilities would be within 20 ft. from the trunk on two sides of the tree. Building G would be installed approximately 40 ft. from the trunk on the north. The required clearance for project streets is 26 ft., to accommodate fire trucks. A large scaffold limb extends across the proposed street towards Building R. Street clearance of 26 ft. above the roadway could require removal of this scaffold. This would reduce the size of the tree’s crown but leave a large pruning wound on the trunk. To ensure successful retention, the tree would require a TREE PROTECTION ZONE of 75 ft. in all directions. Given the design of the project, such a TREE PROTECTION ZONE cannot be provided. I therefore recommend removal of tree #77. I recommend that the project relocate valley oak #83. This is a 13 in. diameter and in excellent condition (Photo 7) Photo 7. Looking west at valley oak #83. Tree Report. January 4, 2021. HortScience | Bartlett Consulting Oak Road Townhome Condominiums.

January 4, 2021. HortScience | Bartlett Consulting Oak Road Townhome Condominiums. SummerHill Homes. Page 12 There are also six off-site trees to be retained but altered as some construction activity will take place within the dripline:  Valley oak #80. This large oak on the north side of the site will need to be pruned to provide access for construction and the new buildings.  Silver dollar gums #160 and 161 may require minor clearance pruning.  Deodar cedar #168 may require minor clearance pruning.  Red oaks #171 and 172 may require minor clearance pruning. Tree Preservation Guidelines The following are recommendations for design and construction phases that will assist in successful tree preservation. Design recommendations 1. Locate the trunk of valley oak #83 as well as the six off-site trees recommended for preservation. Include trunk locations and tree tag numbers on all plans. 2. Valley oak #83 will be relocated. A tree relocation company with experience in moving this size of tree should develop a relocation program. 3. Establish a TREE PROTECTION ZONE around each tree to be preserved. For off- site trees, the TREE PROTECTION ZONE shall be the property line. 4. Use only herbicides safe for use around trees and labeled for that use, even below pavement. Pre-construction and demolition treatments and recommendations 1. The demolition contractor shall meet with the Consulting Arborist before beginning work to discuss work procedures and tree protection. 2. Trees to be preserved may require pruning to provide adequate clearance from construction activities. All pruning shall be performed by a licensed State of California contractor possessing the C61 classification license and the D49 specification. All pruning shall adhere to the latest editions of the American National Standards Institute Z133 and A300 standards. 3. Install tree protective fencing at the edge of the TREE PROTECTION ZONE. For off- site trees, the project’s security fence will serve as tree protection fencing. Tree protection during construction 1. Any grading, construction, demolition or other work that is expected to encounter tree roots should be monitored by the Consulting Arborist. 2. If injury should occur to any tree during construction, it should be evaluated as soon as possible by the Consulting Arborist so that appropriate treatments can be applied. 3. Fences have been erected to protect trees to be preserved. Fences are to remain until all site work has been completed. Fences may not be relocated or removed without permission of the project superintendent. Tree Report. January 4, 2021. HortScience | Bartlett Consulting Oak Road Townhome Condominiums. SummerHill Homes. Page 13 4. No materials, equipment, spoil, waste or wash-out water may be deposited, stored, or parked within the TREE PROTECTION ZONE (fenced area). 5. Any additional tree pruning needed for clearance during construction must be performed by a qualified arborist and not by construction personnel. 6. Any roots damaged during grading or construction shall be exposed to sound tissue and cut cleanly with a saw. HortScience | Bartlett Consulting James R.

Santa Clara Street San Jose CA Re: 196 N. 3rd Street, San Jose CA Dear Ms. Walsh, The referenced property, also known as the former Scottish Rite Temple or the San Jose Athletic Club is listed in the National Register, and is a historic resource as defied by CEQA. The City of San Jose has asked if the rehabilitation be consistent with the Secretary of the Interior’s Standards for Rehabilitation. Urban programmers was contacted by T. Corona, on behalf the owner to provide a third party professional review of the rehabilitation plans for consistency with the “Standards.” The rehabilitation work that is proposed is to a front open area in front of the historic building and not to the historic building. Background: The Scottish Rite Bodies had this building, their second Temple in San Jose, was designed by Carl Warner who specialized in Masonic architecture in Northern California. The building was constructed in 1924, completed and dedicated in 1925. The Neo-Classic designed building exhibits a continuity of architectural design within the St. James Square Historic District in its columns and ornate detailing – some in Egyptian motifs. The front façade is a symmetrical temple design with a broad stair in the center beginning at the edge of the sidewalk and raising to the first story, and projecting portico with 6 fluted Ionic columns. Both sides of the building recess from the portico and are mirror images of design with evenly spaced windows on the two upper floors and mirror elements on the ground level. Elaborately framed niches are behind tall base structures with Sphinx statues on the top. Further exhibiting the symmetrical design, on each side of the stairs are tall winged Sphinx sculptures with basins on the top representing torches. The building had an auditorium that could seat 1,400 and the largest stage in San Jose, a large kitchen, meeting rooms and a basement that was finished and used as a second or informal hall. By the 1960s the Scottish Rite Bodies were looking for a more convenient location, purchasing acreage and eventually constructing a new Temple in the Willow Glen area, In 1980, the historic building was sold and rehabilitated at a cost of $6,000,000, opening in 1981, as the San Jose Athletic Club. This rehabilitation altered the symmetrical design of the front landscaping by introducing a sectioned ramp on the south side of the property that extends the width of the property on that side accessing the basement from the street. Boxwood, oleander and small bushes were planted against the face of the building and along the ramp. The north side landscaping remained with a patch of lawn and low boxwood hedges in front of the building. During the 1980 rehabilitation, pine trees were planted along the north side of the building. Left untrimmed for many years these began to damage the building and were removed. Marshall Torre, Director of Development SummerHill Homes 3000 Executive Pkwy, Suite 450, San Ramon, CA 94583 Project: Palmer School, Contra Costa County Dear Marshall, In our proposal to SummerHill we described a preliminary assessment of the Palmer School to determine if there were historical or architectural issues that might comply with the criteria of the California Register of Historic Resources. This letter report describes our findings. The majority of the history was obtained in an interview with Sam Mendes, the headmaster and owner of the property. It was his grandparents that started the school and his parents that operated it prior to his term. Bonnie Bamburg and Marvin Bamburg AIA, Historic Architect, viewed the school from the public right of way on September 14, 2020 and will tour with Mr. Mendes within the next week. Background: The Palmer School was started with Elizabeth Palmer as the teacher, in 1938 as a small alternative school to the public schools in the area. The school is not associated with a religious or other institution or persuasion. Originally a boarding school for girls increasing to 35 students before it was made co-ed in the 1950s, without boarding students, and grew to 340 students in grades K-8. The educational philosophy was structured but does not appear to have followed any specific organized method. The school did not discriminate and had a population of students from upper middle class and high achieving families. The school closed June 5, 2020 due to the Covid 19 pandemic and County Health Department Orders that precluded in-person instruction or to carry on the normal activities of the school. At this time no graduates who later achieved significance have been identified. No events of local, state or national significance have been associated with the school. The school appears to have operated with little cultural association within the City of Walnut Creek or Contra Costa County. The school began in a small house (c. 1938 still on campus) and then to adjoining houses (c.1945) where students boarded. The first building was constructed in 1945 and moved in 1962. Others were constructed in 1959,1961,1962,1963, 1984. These were altered and added to as necessary.. There is no distinctive, unusual, or artistic design on the campus. Based upon the history and architecture of the Palmer School Campus, we do not find it eligible for listing in the California Register of Historic Resources. September 15, 2020 Preliminary Assessment Palmer School 2 Regulatory Framework as we understand it for Contra Costa County. It is likely the proposed residential development will require an EIR or some focused sections. The California Environmental Quality Act considers buildings over 50 years old to be potential historic resources and thus recommends to lead agencies that a study of the property be conducted to provide the lead agency with that information. CEQA is encoded in sections 21000et.seq of the Public Resources Code (PRC) with Guidelines for implementation codified in the California Code of Regulations (CCR), Title 14,Chapter 3,Sections 15000 et seq., requires the state and local public agencies to identify the environmental impacts of proposed discretionary activities of project, determine if the impacts will be significant, and identify alternatives and mitigation measures that will substantially reduce or eliminate significant impacts to the environment. Historical resources are considered part of the environment and a project that may cause a substantial adverse effect on the significance of a historical resource is a project that may have a significant effect on the environment. The definition of "historical resources" is contained in Section 15064.5 of the CEQA Guidelines. The criteria of significance recognized by CEQA is that of the California Register of Historical Resources; Criterion 1• Associated with events that have made a significant contribution to the broad patterns of local or regional history or the cultural heritage of California or the United States. Criterion 2• Associated with the lives of persons important to local, California or national history. Criterion 3• Embodies the distinctive characteristics of a type, period, region or method of construction or represents the work of a master or possesses high artistic values. Criterion 4• Has yielded, or has the potential to yield, information important to the prehistory or history of the local area, California or the nation. We believe the lead agency will require a report describing the history and architectural values in comparison to the above criteria. It is our opinion that the property does not qualify under any of the criteria, however to avert challenges later in the entitlement process, it is recommended that the need for a third party consultant report be discussed with the County early in the process.

proposed residential development at 2740 Jones Road in Walnut Creek, California. We performed the following scope of services:  Review of published geologic maps, aerial photographs, historic topography, and publically available geologic and groundwater information in the area.  Limited subsurface explorations.  Data analysis and development of preliminary geotechnical recommendations.  Report preparation. This report was prepared for the exclusive use of SummerHill Homes and their design team consultants. In the event that any changes are made in the character, design or layout of the development, we must be contacted to review the conclusions and recommendations contained in this report to evaluate whether modifications are recommended. This document may not be reproduced in whole or in part by any means whatsoever, nor may it be quoted or excerpted without our express written consent. 1.2 PROJECT LOCATION AND DESCRIPTION The site location is presented on Figure 1, the Vicinity Map. The site address is 2740 Jones Road in Walnut Creek and is associated with Assessor’s Parcel Number (APN) 172-012-020-1. The parcel is approximately 5.5 acres in size and is currently occupied by a private school and its associated facilities such as sport field and courts, a swimming pool, and surface parking lots. As shown on the Site Plan, Figure 2, the site is bounded by Jones Road on the west, Oak Road on the east, two apartment buildings and one condominium complex to the north, and the Oak Road Villas condominium to the south. Based on conversations with you and review of the preliminary site plans and renderings, we understand that the proposed development will consist of three-story multi-family townhome/condominium development, associated parking, and landscape areas. We anticipate the development to consist of three-story at grade structures with no below-grade levels. Grading plans were not available at the time of this report preparation, but we anticipate minor cuts and fills will be conducted to accommodate the development. We anticipate that the structures will be of wood-frame construction. Therefore, in our opinion, the building loads are estimated to be light to moderately light. 2.0 FINDINGS 2.1 HISTORICAL AERIAL PHOTOGRAPH REVIEW Review of historical aerial photographs found the property associated with parcel 172-012-020-1 was primarily used for agricultural purposes prior to 1939. Historical records indicate that the property has been occupied by a private school, Palmer School for Boys and Girls, since 1939. SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 2 September 1, 2020 Review of historical aerial photographs from the period 1939 through 2019 show that the site has remained relatively unchanged from current conditions since 1968, aside from the removal of two additional pools on the property. Between the years of 1939 and 1968, the property transitioned from a sparsely developed parcel with clusters of small buildings, amidst open space and orchards, to the current development. 2.2 GEOLOGY AND SEISMICITY 2.2.1 Regional Geology The site is located within the Coast Ranges geomorphic province of California. The Coast Ranges geomorphic province is characterized by a system of northwest-trending, fault-bounded mountain ranges and intervening alluvial valleys. Bedrock in the Coast Ranges consists of igneous, metamorphic and sedimentary rocks that range in age from Jurassic to Pleistocene. The present topography and geology of the Coast Ranges are the result of deformation and deposition along the tectonic boundary between the North American plate and the Pacific plate. Plate boundary fault movements are largely concentrated along the well-known fault zones, which in the area include the San Andreas, Hayward, and Calaveras faults, as well as other lesser-order faults. 2.2.2 Geology More specifically, the site is located within the west portion of Ygnacio Valley. Ygnacio Valley represents an area of low relief, between Mount Diablo within the Diablo Range to the east and the Briones Hills within the East Bay Hills to the west. Both Witter (2006) and Helley (1997) m ap the geology at the site as alluvial fan deposits; however, Witter interprets the deposits as Holocene and Helley interprets them as Pleistocene. Dibblee (2005) interprets the map surficial deposits as a combination of Holocene and Pleistocene. The alluvial deposits are commonly unconsolidated, heterogeneous, poorly to moderately sorted, irregularly interbedded clays and silts containing discontinuous lenses of sand, silty clay, and gravel. According to Witter (2006), the alluvial deposits underlying the site are considered of moderate liquefaction susceptibility. Our relevant experience in the area indicates that the alluvium may consist of moderately to highly expansive clay to sandy clay. Bedrock exposed in the Briones Hill directly west of the site generally comprises units of the Monterey Formation and Martinez Group. 2.2.3 Seismicity The Bay Area area contains numerous active earthquake faults. Nearby active faults include the Contra Costa (Larkey) fault, which has a nearest rupture distance of approximately 1.3 miles from the project site and the Franklin fault, which has a nearest rupture distance of approximately 1.6 miles west of the project site. An active fault is defined by the California Geologic Survey as one that has had surface displacement within Holocene time (about the last 11,000 years) (Bryant and Hart, 2007). The site is not located within a currently designated Alquist-Priolo Earthquake Fault Zone and no known surface expression of active faults is believed to exist within the site. Fault rupture through the site, therefore, is not anticipated. Numerous small earthquakes occur every year in the San Francisco Bay Region, and larger earthquakes have been recorded and can be expected to occur in the future. Figure 4 shows the approximate locations of these faults and significant historic earthquakes recorded within the San Francisco Bay Region. The Uniform California Earthquake Rupture Forecast (UCERF 3) SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 3 September 1, 2020 (Field et al, 2015) estimates the 30-year probability for a magnitude 6.7 or greater earthquake in Southern California at approximately 72 percent, considering the known active seismic sources in the region. To determine nearby active faults that are capable of generating strong seismic ground shaking at the site, we utilized the USGS Unified Hazard Tool* and disaggregated the hazard at the peak ground acceleration (PGA) and at period of 0.5 seconds for 2475-year return period, with the resulting faults listed below in Table 2.2.3-1. TABLE 2.2.3-1: Active Faults Capable of Producing Significant Ground Shaking at the Site, Latitude: 37.924022° Longitude: -122.058775° SOURCE RRUP MOMENT MAGNITUDE MW (KM) (MILES) Contra Costa (Larkey) [1] 2.02 1.26 6.29 Franklin [1] 2.54 1.58 7.10 Mount Diablo Thrust North CFM [1] 3.62 2.25 7.15 Contra Costa Shear Zone (connector) [4] 4.93 3.06 7.10 Concord [2] 5.08 3.16 6.65 Contra Costa (Lafayette) [1] 5.12 3.18 7.02 Concord [1] 8.81 5.47 6.57 Calaveras (No) [0] 9.83 6.11 7.03 Clayton [0] 10.43 6.48 6.92 Hayward (No) [1] 16.99 10.56 7.33 *USGS Unified Hazard Tool - Edition: Dynamic Conterminous U.S. 2014 (update) (v4.2.0) 2.3 FIELD EXPLORATION We retained a truck-mounted rig to advance two cone penetration tests (CPTs) and one seismic cone penetration test (SCPT) to a maximum depth of approximately 78 feet below the ground surface (bgs). Figure 2 presents these exploration locations. The CPT equipment has a 20-ton compression-type cone with a 10-square-centimeter (cm2) base area and a friction sleeve with a surface area of 150 cm2. The cone, connected with a series of rods, is pushed into the ground at a constant rate. Cone readings are taken at approximately 5-cm intervals with a penetration rate of 2 cm per second in accordance with ASTM standards (D3441). Measurements include the tip resistance to penetration of the cone (Qc), the resistance of the surface sleeve (Fs), and dynamic pore pressure (U). Pore pressure dissipation tests were conducted at all three locations. The CPT cone was halted at select depths, and the variation of the penetration pore pressure with time was measured until the pore pressure stabilized. Shear wave velocity (Vs) tests were conducted at 1-meter intervals in 1-SCPT2. The SCPT cone was halted at select depths, and the time needed for shear waves to travel from the ground to a geophone in the SCPT cone was recorded and used to calculate Vs. Appendix A presents the CPT data. The CPT and SCPT holes were permitted and backfilled with cement grout upon completion per requirements of Contra Costa County Health Services. SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 4 September 1, 2020 2.4 SURFACE CONDITIONS According to published topographic maps and Google Earth elevations, the Property is relatively level at an elevation of approximately 93 to 95 feet, based on the North American Vertical Datum of 1988 (NAVD 88). The project site contains several structures, including school facilities, a tennis court, a basketball court, a swimming pool, a field, and a parking lot. The site is vegetated, with several large deciduous trees throughout the Property and additional smaller trees and bushes along the southern and western edges of the site. 2.5 SUBSURFACE CONDITIONS Alluvial deposits were found in 1-CPT1, 1-SCPT2, and 1-CPT3, and the granular materials in the upper 40 feet appear to be discontinuous layers at different elevations across the site. Between 40 and 50 feet bgs, a dense to very dense sand and gravelly sand layer was found in all three borings. Based on CPT soil behavior type correlations (SBT) by Robertson (2009, 2016), the native material encountered in 1-CPT1 was primarily composed of layers between approximately 1 and 12 feet thick of medium-dense to loose sand and medium stiff to very soft silt-like and clay-like material. A medium dense to very dense sand layer was found between 18 and 24 feet bgs, and at approximately 48 feet bgs. The material encountered in 1-SCPT2 was mostly composed of discontinuous layers up to 6 feet in thickness of medium stiff to very soft silty and clayey mixtures with interbedded pockets of loose to very dense sand deposits. A lens of dense to very dense sand was found between depths of 41 and 49 feet bgs. The native material found in the upper 40 feet of 1-CPT3 was primarily a continuous deposit of soft to very soft silty clay and clayey silt. A lens of dense to very dense sand and gravelly sand was found between depths of 41 and 49 feet bgs. Consult the Site Plan and exploration logs for specific subsurface conditions at each location. We include the CPT exploration report in Appendix A. The report contains the soil behavior type classification, calculated using measurements of cone tip resistance, skin friction, and excess pore pressure. The report graphically depicts the subsurface condition interpretation at the time of the exploration. 2.6 GROUNDWATER CONDITIONS During The CPT explorations, we performed pore pressure dissipation (PPD) tests, as described in Appendix A, to infer approximate groundwater table elevations, summarized in the table below. Elevations are based on NAVD88. TABLE 2.6-1: Groundwater Observations EXPLORATION LOCATION APPROX. DEPTH TO GROUNDWATER (FEET) APPROX.

Future irrigation may cause an overall rise in groundwater levels. 3.0 DISCUSSION AND CONCLUSIONS From a geotechnical engineering viewpoint, in our opinion, the site is suitable for the proposed development, provided the preliminary geotechnical recommendations in this report are properly addressed. The primary geotechnical concerns that could affect development on the site are liquefaction-induced settlement, potential consolidation of compressible material, potential expansive soil, and areas of shallow ground water. The preliminary recommendations included in this report should be utilized for project planning purposes and are intended for the areas of the site that will be developed with structural improvements. These areas include, but are not limited to building pads, sidewalks, pavement areas, and retaining walls. Prior to development, we should be retained to provide a design-level geotechnical report for the development, which would include additional CPTs, borings and laboratory testing to provide data for preparation of specific recommendations regarding site grading, foundations, and drainage for the proposed development. We evaluated the site was with respect to known geologic and other hazards common to the area. The primary hazards and the risks associated with these hazards with respect to the planned development are discussed in the following sections of this report. 3.1 SEISMIC HAZARDS Potential seismic hazards resulting from a nearby moderate to major earthquak e can generally be classified as primary and secondary. The primary effect is ground rupture, also called surface faulting. The common secondary seismic hazards include ground shaking and ground lurching. The following sections present information regarding these hazards as they apply to the site. Based on site observations, topographic and lithologic data, subsurface data, and regional geology, the risk of regional subsidence or uplift, lateral spreading, landslides, tsunamis, flooding or seiches is considered low to negligible at the site. 3.1.1 Ground Rupture The site is not located within a State of California Earthquake Fault Hazard Zone and no known faults cross the site (California Geologic Survey Walnut Creek Quadrangle, 1993). Therefore, it is our opinion that ground rupture is unlikely at the subject property. 3.1.2 Ground Shaking An earthquake of moderate to high magnitude generated within the Northern California region could cause considerable ground shaking at the site, similar to that which has occurred in the past. To mitigate the shaking effects, structures should be designed using sound engineering judgment and the 2019 California Building Code (CBC) requirements, as a minimum. SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 6 September 1, 2020 3.1.3 Liquefaction Soil liquefaction results from loss of strength during cyclic loading, such as imposed by earthquakes. Soil most susceptible to liquefaction are clean, loose, saturated, unif ormly graded, fine-grained sand below the groundwater table. When seismic ground shaking occurs, the soil is subjected to cyclic shear stresses that can cause excess hydrostatic pressures to develop and cause liquefaction of susceptible soil. Review of the US Geologic Survey (USGS) liquefaction susceptibility map (Knudsen et al, 2000) for this area indicates that the site is located within an area with moderate susceptibility to liquefaction (Figure 5). We assessed liquefaction potential at the site by performing liquefaction analyses utilizing data obtained from the CPT probes. We assigned a design groundwater level of 10 feet below the existing ground surface, a peak ground acceleration (PGA) of 0.88g, and a maximum moment magnitude (Mw) of 7.0. Our analyses were based on guidelines provided in DMG Special Publication 117A (2008) and methods developed by the National Center for Earthquake Engineering Research (1998), Moss et al. (2006), Idriss and Boulanger (2008), and Boulanger and Idriss (2014). We calculated the vertical settlements based on the procedure recommended by Zhang et al (2002). Based on our limited subsurface explorations and liquefaction analysis (Appendix B), we estimate that a maximum of 4¾ inches of total liquefaction-induced settlement may occur during a maximum considered event (MCE) earthquake. This amount of total liquefaction-induced settlement corresponds to less than 2½ inches of differential settlement over a horizontal distance of 40 feet. Based on our experience, it is our understanding that this amount of differential settlement can be accommodated by the structural engineer in the foundation design. Additional subsurface exploration, collection of soil samples, and laboratory testing during the design-level study will better delineate the areas with a potential for liquefaction, and may help to optimize estimates of liquefaction-induced settlement magnitude. 3.1.4 Lateral Spreading Lateral spreading is a failure within a nearly horizontal soil zone (possibly due to liquefaction) that causes the overlying soil mass to move toward a free face or down a gentle slope. Generally, effects of lateral spreading are most significant at the free face or the crest of a slope and diminish with distance from the slope. Based on site topography and subsurface conditions, it is our opinion that the risk of lateral spreading at the site is low. 3.2 COMPRESSIBLE SOIL Soil is subject to consolidation settlement when a new loading scenario is introduced by structures, earthworks or equipment. The amount of consolidation settlement is dependent on the magnitude and duration of the applied load, the shape and size of the applied load area , the depth, thickness and the stress history of the compressible soil. The time required for primary consolidation settlement to occur is highly dependent on the permeability of the deposit. Consequently, sandy soil will settle almost immediately, whereas clayey soil will settle much more slowly. Based on review of the CPT data, it is our opinion that the subsurface clay and silt mixture material at depths of 0 to 27 feet and 31 to 37 feet are very soft to soft and may undergo consolidation under loads from additional fill required to grade the site and proposed buildings. Based on our knowledge and experience, it is our opinion that a portion of the consolidation will occur during SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 7 September 1, 2020 construction, and that the remaining differential consolidation-induced settlement can be accommodated in the structural foundation design. Laboratory testing and additional analysis should be performed in the design-level study to confirm the magnitude and extent of the potentially compressible material and the potential consolidation-induced settlement. 3.3 EXISTING NON-ENGINEERED FILL We cannot determine the extent of the existing non-engineered fill based on present exploration data. Based on our review of aerial photos and historical records, it appears as though the site has had a history of agricultural activities prior to 1960s. From the review of historic aerial photos (https://www.historicaerials.com) and historic topographic maps dating to the 1890s, the topography of the site does not appear to have changed significantly at any point. Therefore , we expect to encounter minor (less than 5 feet) of non-engineered fill across most of the site. There may be localized areas of deeper fill beneath existing and previous structure foundations, such as under the three swimming pools that were constructed on the site since the 1940s. We recommend that a design-level geotechnical exploration with borings be conducted to evaluate the existence and extent of potential non-engineered fill. Non-engineered fill can undergo excessive settlement, especially under new fill or building loads. In general, undocumented fill should be excavated, and if deemed suitable for reuse, replaced as engineered soil fill. The extent and quality of existing fill should be evaluated at the time of design-level study and mitigated during remedial grading activities. Based on the available data, it is our opinion that significant amounts of undocumented fill will not be present across the majority of the site. 3.4 EXPANSIVE SOIL Sampling and testing for expansiveness potential was not performed as part of this preliminary study. While we did not observe potentially expansive soil during the site exploration, the CPT data suggests clayey soil is present at the site, which may exhibit expansive potential based on their flood plain origin. The presence of potentially expansive soil should be further evaluated during the design-level geotechnical exploration. Expansive soil change in volume with changes in moisture. They can shrink or swell and cause heaving and cracking of slabs-on-grade, pavements, and structures founded on shallow foundations. Building damage due to volume changes associated with expansive soil can be reduced by: (1) using a rigid mat foundation that is designed to resist the settlement and heave of expansive soil, (2) deepening the foundations to below the zone of moisture fluctuation, i.e. by using deep footings or drilled piers, and/or (3) using lime treatment in the upper 18 inches of the building pad to reduce the expansion potential of the onsite soil. To mitigate potential damage from expansive soil, selective grading or blending would be necessary to create relatively low expansion potential surface conditions. Selective grading typically involves careful planning of cut and fill along with blending and disking to mix soil types and create low expansion soil conditions. Creating low expansion conditions can necessitate more complicated cut/fill operations and multiple blending operations that can increase earthwork costs. SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 8 September 1, 2020 3.5 CORROSIVITY CONSIDERATIONS Sampling and testing for corrosion potential was not performed as part of this preliminary study. Representative samples of the foundation grade soil should be obtained during the design-level geotechnical exploration to determine the potential for corrosion on buried metal and the potential for sulfate attack on foundation concrete. Based on the test results, the corrosion potential can be described and the recommended concrete design parameters can be developed in accordance with the guidelines presented in the 2019 CBC. If subsurface transformers are proposed for the development, we recommend that the subsurface samples be obtained and tested in accordance with recommendations set forth by Pacific Gas and Electric. 3.6 SHALLOW GROUNDWATER We summarized groundwater conditions at this site in Table 2.6-1. The groundwater table was found at a depth of ranging from 10 to 19 feet below grade depending on location. Based on the groundwater data and our experience, we believe the groundwater level may rise in the future. As such, we recommend that a groundwater level of 10 feet below ground surface be considered for preliminary design. Based on the groundwater levels interpreted in the CPTs and historical groundwater depth for the site, it appears that shallow groundwater beneath the site could potentially affect the proposed development. Shallow groundwater can:  Impede grading activities.  Require construction dewatering during grading and improvement.  Cause moisture damage to sensitive floor coverings.  Transmit moisture vapor through slabs causing excessive mold/mildew build-up, fogging of windows, and damage to computers and other sensitive equipment. Based on the groundwater measurements observed during our CPT explorations, we believe that the foundation construction process should be just above the existing static groundwater; however, site utilities may extend below those depths and encounter static groundwater during construction. Existing fill removal and any deep utility trench excavation may encountered groundwater. Shallow groundwater condition should be considered during design of utilities, site grading, and excavation of the utility trenches and foundation. The project contractor should evaluate the site conditions and selected properly designed dewatering, shoring systems, and other as necessary during site grading and construction. Seasonal fluctuations can potentially raise and lower the groundwater level from the depths observed during the time of our explorations. 3.7 FLOODING Flood Insurance Map by FEMA (Figure 6) indicates that the project site is outside of mapped flood zones within its boundaries. Therefore, it is our opinion that the risk of flooding is low at this site. The Civil Engineer should review the pertinent information relating to flood levels for the project site based on final pad elevations and provide appropriate design measures for development of the project, if necessary. SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 9 September 1, 2020 3.8 2019 CBC SEISMIC DESIGN PARAMETERS Based on the subsurface conditions encountered and shear wave velocity measurements, we characterized the site as Site Class D in accordance with the 2019 CBC. We provide the 2019 CBC seismic design parameters in Table 3.8-1 below, which include design spectral response acceleration parameters based on the mapped Risk Targeted Maximum Considered Earthquake (MCER) spectral response acceleration parameters. TABLE 3.8-1: 2019 CBC Seismic Design Parameters, Latitude: 37.924022° Longitude: -122.058775° PARAMETER VALUE Site Class D Mapped MCER Spectral Response Acceleration at Short Periods, SS (g) 1.971 Mapped MCER Spectral Response Acceleration at 1-second Period, S1 (g) 0.640 Site Coefficient, Fa 1.00 Site Coefficient, Fv Null* MCER Spectral Response Acceleration at Short Periods, SMS (g) 1.971 MCER Spectral Response Acceleration at 1-second Period, SM1 (g) Null* Design Spectral Response Acceleration at Short Periods, SDS (g) 1.314 Design Spectral Response Acceleration at 1-second Period, SD1 (g) Null* Mapped MCE Geometric Mean (MCEG) Peak Ground Acceleration, PGA (g) 0.804 Site Coefficient, FPGA 1.10 MCEG Peak Ground Acceleration adjusted for Site Class effects, PGAM (g) 0.885 *Requires site-specific ground motion hazard analysis per ASCE 7-16 Section 11.4.8 Considering the proposed residential development, we estimate the fundamental periods of the proposed structures to be less than 1.5Ts (where Ts is 0.55 seconds for this project). Therefore, the structural engineer may consider exception(s) of Section 11.4.8 of ASCE 7-16 as follows: “A ground motion hazard analysis is not required for structures… where, structures on Site Class D sites with S1 greater than or equal to 0.2, provided the value of the seismic response coefficient Cs is determined by Eq. (12.8-2) of ASCE 7-16 for values of 𝑇≤1.5𝑇𝑆 and taken as equal to 1.5 times the value computed in accordance with Eq. (12.8-3) of ASCE 7-16 for 1.5𝑇𝑠<𝑇≤𝑇𝐿.” However, based on our experience, a site-specific seismic hazard analysis can optimize the spectral values at the short period range. We recommend that we collaborate with the structural engineer of record to further evaluate the effects of taking the exceptions on the structural design and identify the need for performing a site-specific seismic hazard analysis. We can provide a scope for site-specific seismic hazard analysis and ground motion study under separate cover, if needed. 3.9 PRELIMINARY FOUNDATION RECOMMENDATIONS We anticipate the proposed residential development can be supported by a post-tensioned mat foundation. Based on our understanding of the presence of expansive soil in the area, as well as the potential for liquefaction-induced settlements of up to 4¾ inches, we do not recommend the SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 10 September 1, 2020 use of conventional footings with a concrete slab-on-grade. We provide preliminary recommendations for the post-tensioned mat foundation below. 3.9.1 Post-tension Mat Foundation We recommend that the proposed residential structures be supported on post-tensioned (PT) mat foundations bearing on engineered fill. On a preliminary basis, we recommend that PT mats be a minimum of 10 inches thick or greater and have a thickened edge at least 2 inches greater than the mat thickness. The Structural Engineer should determine the actual PT mat thickness using the geotechnical recommendations in the design-level report. We recommend that the thickened edge be at least 12 inches wide. PT mats are typically underlain by a moisture reduction system as recommended below. In addition, the building pad subgrade is typically moisture conditioned such that the subgrade soil is at a moisture content at least 3 percentage points above optimum immediately prior to foundation construction. The subgrade should not be allowed to dry prior to concrete placement. 3.9.2 Slab Moisture Vapor Reduction When buildings are constructed with a concrete slab-on-grade, including post-tensioned mats, water vapor from beneath the slab will migrate through the slab and into the building. This water vapor can be reduced but not stopped. Vapor transmission can negatively affect floor coverings and lead to increased moisture within a building. When water vapor migrating through the slab would be undesirable, we typically recommend a moisture retarder system to reduce, but not stop, water vapor transmission upward through the slab-on-grade. This generally involves installing a Class A vapor retarder membrane (ASTM E1745, latest edition), underlain by 4 inches of clean crushed rock. The structural engineer should be consulted as to the use of a layer of clean sand or pea gravel (less than 5 percent passing the U.S. Standard No. 200 Sieve) placed on top of the vapor retarder membrane. Lastly, we typically recommend a concrete water-cement ratio for slabs-on-grade of no more than 0.50, special inspections during concrete placement, and moist curing slabs for a minimum of 3 days (or other equivalent curing specified by the structural engineer). 4.0 PRELIMINARY EARTHWORK RECOMMENDATIONS 4.1 GENERAL SITE CLEARING AND DEMOLITION After demolition of the existing buildings, paving, and associated improvements, the site should be cleared of all obstructions, including existing foundations, and debris. Any existing underground utilities within the proposed development area should be identified and removed entirely including pipes and their backfill. Depressions resulting from the removal of underground obstructions extending below the proposed finish grades should be cleared and backfilled with suitable material compacted to the recommendations presented in Section 5.3. Areas containing surface vegetation or organic laden topsoil within the areas to be improved should be stripped to an appropriate depth to remove these materials. The amount of actual stripping and tree root removal should be determined in the field by the Geotechnical Engineer at the time of construction. Subject to approval by the Landscape Architect, strippings and organically contaminated soil can be used in landscape areas. Otherwise, such soil should be SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 11 September 1, 2020 removed from the project site. Any topsoil that will be retained for future use in landscape areas should be stockpiled in areas where it will not interfere with grading operations. Stripping and demolition below design grades should be cleaned to a firm undisturbed soil surface determined by the Geotechnical Engineer. This surface should then be cleaned, scarified, moisture conditioned, and backfilled with suitable material compacted to the recommendations presented in the Fill Compaction section. No loose or uncontrolled backfilling of depressions resulting from demolition and stripping should be permitted. 4.1 NON-ENGINEERED FILL As described previously, we expect the presence of non-engineered fill at the site. Where applicable, existing fill, existing utility trench backfill, existing foundation backfill, and existing landscape materials are considered undocumented and should be subexcavated to expose underlying competent native soil that is approved by the Geotechnical Engineer. If in a fill area, the base of the excavations should be processed, moisture conditioned, as needed, and compacted in accordance with the recommendations for engineered fill. 4.2 SELECTION OF MATERIALS With the exception of construction debris (wood, brick, asphalt, concrete, metal, etc.), trees, high organic content soil (soil which contains more than 3 percent organic content by weight), and environmentally impacted soil (if any), we anticipate the site soil is suitable for use as engineered fill. Other material and debris, including trees with their root balls, should be removed from the project site. 4.3 FILL COMPACTION We recommend removal of existing fills (if encountered during grading), stripping of organics, scarification, moisture conditioning, and compaction of the soil prior to fill placement, following cutting operations, and in areas left at grade. For land planning and cost estimating purposes, the following compaction control requirements should be anticipated for general fill areas.  Test Procedures: ASTM D-1557.  Required Moisture Content: Not less than 3 percentage points above optimum moisture content.  Minimum Relative Compaction: Not less than 90 percent. Relative compaction refers to the in-place dry density of soil expressed as a percentage of the maximum dry density of the same material. In the event that imported fill material is characterized and following the design level geotechnical report, the recommendations may change with respect to the soil type 4.4 FLEXIBLE PAVEMENT Based on our experience with nearby developments, we judged an R-value of 5 to be appropriate for preliminary pavement design. Using a preliminary design R-value of 5 and Procedure 633 of the Caltrans Highway Design Manual (including the asphalt factor of safety), we developed the following pavement sections presented in Table 4.4-1 below. SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 12 September 1, 2020 TABLE 4.4-1: Preliminary Pavement Sections TRAFFIC INDEX HOT MIX ASPHALT (inches) CLASS 2 AGGREGATE BASE (inches) 5 3 10 6 3½ 13 7 4 16 The civil engineer should determine the appropriate traffic indices based on the estimated traffic loads and frequencies. 4.5 SURFACE DRAINAGE The project Civil Engineer is responsible for designing surface drainage improvements. With regard to geotechnical engineering issues, we recommend that finish grades be sloped away from buildings and pavements to the maximum extent practical to reduce the potentially damaging effects of expansive soil. The latest CBC Section 1804.3 specifies minimum slopes of 5 percent away from foundations. As a minimum, we recommend the following: 1. Discharge roof downspouts into closed conduits and direct away from foundations to appropriate drainage devices. 2. Consider the use of surface drainage collection system to reduce ponding of water at the ground surface near the foundation, pavements or exterior flatwork. 5.0 DESIGN-LEVEL GEOTECHNICAL REPORT This report presents geotechnical feasibility findings and considerations for the planned residential development. A design-level geotechnical exploration should be performed when development plans are finalized. The purpose of the design-level exploration is to further evaluate the liquefaction, liquefaction-induced settlement, potential for excessive amounts of fill, compressible soil and other geotechnical hazards. Specific recommendations for site grading, ground improvement, and the design and construction of foundations and utilities should be included in the design-level geotechnical report. 6.0 LIMITATIONS AND UNIFORMITY OF CONDITIONS This preliminary report is issued with the understanding that it is the responsibility of the owner to transmit the information and recommendations of this report to developers, owners, buyers, architects, engineers, and designers for the project so that the necessary steps can be taken by the contractors and subcontractors to carry out such recommendations in the field. The conclusions and recommendations contained in this preliminary report are solely professional opinions. The professional staff of ENGEO strives to perform its services in a proper and professional manner with reasonable care and competence but is not infallible. There are risks of earth movement and property damages inherent in land development. We are unable to eliminate all risks or provide insurance; therefore, we are unable to guarantee or warrant the results of our services. SummerHill Homes Palmer, Walnut Creek 17567.000.000 Preliminary Geotechnical Exploration Page | 13 September 1, 2020 This preliminary report is based upon field and other conditions discovered at the time of preparation of ENGEO’s report. This document must not be subject to unauthorized reuse that is, reusing without written authorization of ENGEO. Such authorization is essential because it requires ENGEO to evaluate the document’s applicability given new circumstances, not the least of which is passage of time. Actual field or other conditions will necessitate clarifications, adjustments, modifications or other changes to ENGEO’s documents. Therefore, ENGEO must be engaged to prepare the necessary clarifications, adjustments, modifications or other changes before construction activities commence or further activity proceeds. If ENGEO’s scope of services does not include on-study area construction observation, or if other persons or entities are retained to provide such services, ENGEO cannot be held responsible for any or all claims arising from or resulting from the performance of such services by other persons or entities, and from any or all claims arising from or resulting from clarifications, adjustments, modifications, discrepancies or other changes necessary to reflect changed field or other conditions.

A detailed set of calculated CPTu parameters have been generated and are provided in Excel format files in the release folder. The CPTu parameter calculations are based on values of corrected tip resistance (qt) sleeve friction (fs) and pore pressure (u2). Effective stresses are calculated based on unit weights that have been assigned to the individual soil behaviour type zones and the assumed equilibrium pore pressure profile. Soils were classified as either drained or undrained based on the Qtn Normalized Soil Behaviour Type Chart (Robertson, 2009). Calculations for both drained and undrained parameters were included for materials that classified as silt mixtures (zone 4).

In order to properly understand the factual data, assumptions and calculations, reference must be made to the documents provided and their accompanying data sets, in their entirety. CONE PENETRATION TEST The cone penetration tests (CPTu) are conducted using an integrated electronic piezocone penetrometer and data acquisition system manufactured by Adara Systems Ltd. of Richmond, British Columbia, Canada. ConeTec’s piezocone penetrometers are compression type designs in which the tip and friction sleeve load cells are independent and have separate load capacities. The piezocones use strain gauged load cells for tip and sleeve friction and a strain gauged diaphragm type transducer for recording pore pressure. The piezocones also have a platinum resistive temperature device (RTD) for monitoring the temperature of the sensors, an accelerometer type dual axis inclinometer and a geophone sensor for recording seismic signals. All signals are amplified down hole within the cone body and the analog signals are sent to the surface through a shielded cable. ConeTec penetrometers are manufactured with various tip, friction and pore pressure capacities in both 10 cm2 and 15 cm2 tip base area configurations in order to maximize signal resolution for various soil conditions. The specific piezocone used for each test is described in the CPT summary table presented in the first Appendix. The 15 cm2 penetrometers do not require friction reducers as they have a diameter larger than the deployment rods. The 10 cm2 piezocones use a friction reducer consisting of a rod adapter extension behind the main cone body with an enlarged cross sectional area (typically 44 mm diameter over a length of 32 mm with tapered leading and trailing edges) located at a distance of 585 mm above the cone tip. The penetrometers are designed with equal end area friction sleeves, a net end area ratio of 0.8 and cone tips with a 60 degree apex angle. All ConeTec piezocones can record pore pressure at various locations. Unless otherwise noted, the pore pressure filter is located directly behind the cone tip in the “u2” position (ASTM Type 2). The filter is 6 mm thick, made of porous plastic (polyethylene) having an average pore size of 125 microns (90-160 microns). The function of the filter is to allow rapid movements of extremely small volumes of water needed to activate the pressure transducer while preventing soil ingress or blockage. The piezocone penetrometers are manufactured with dimensions, tolerances and sensor characteristics that are in general accordance with the current ASTM D5778 standard. ConeTec’s calibration criteria also meet or exceed those of the current ASTM D5778 standard. An illustration of the piezocone penetrometer is presented in Figure CPTu. CONE PENETRATION TEST Figure CPTu. Piezocone Penetrometer (15 cm2) The ConeTec data acquisition systems consist of a Windows based computer and a signal conditioner and power supply interface box with a 16 bit (or greater) analog to digital (A/D) converter. The data is recorded at fixed depth increments using a depth wheel attached to the push cylinders or by using a spring loaded rubber depth wheel that is held against the cone rods. The typical recording intervals are either 2.5 cm or 5.0 cm depending on project requirements; custom recording intervals are possible. The system displays the CPTu data in real time and records the following parameters to a storage media during penetration:  Depth  Uncorrected tip resistance (qc)  Sleeve friction (fs)  Dynamic pore pressure (u)  Additional sensors such as resistivity, passive gamma, ultra violet induced fluorescence , if applicable All testing is performed in accordance to ConeTec’s CPT operating procedures which are in general accordance with the current ASTM D5778 standard. CONE PENETRATION TEST Prior to the start of a CPTu sounding a suitable cone is selected, the cone and data acquisition system are powered on, the pore pressure system is saturated with either glycerin or silicone oil and the baseline readings are recorded with the cone hanging freely in a vertical position. The CPTu is conducted at a steady rate of 2 cm/s, within acceptable tolerances. Typically one meter length rods with an outer diameter of 1.5 inches are added to advance the cone to the sounding termination depth. After cone retraction final baselines are recorded. Additional information pertaining to ConeTec’s cone penetration testing procedures:  Each filter is saturated in silicone oil or glycerin under vacuum pressure prior to use  Recorded baselines are checked with an independent multi-meter  Baseline readings are compared to previous readings  Soundings are terminated at the client’s target depth or at a depth where an obstruction is encountered, excessive rod flex occurs, excessive inclination occurs, equipment damage is likely to take place, or a dangerous working environment arises  Differences between initial and final baselines are calculated to ensure zero load offsets have not occurred and to ensure compliance with ASTM standards The interpretation of piezocone data for this report is based on the corrected tip resistance (qt), sleeve friction (fs) and pore water pressure (u). The interpretation of soil type is based on the correlations developed by Robertson (1990) and Robertson (2009). It should be noted that it is not always possible to accurately identify a soil type based on these parameters. In these situations, experience, judgment and an assessment of other parameters may be used to infer soil behavior type. The recorded tip resistance (qc) is the total force acting on the piezocone tip divided by its base area. The tip resistance is corrected for pore pressure effects and termed corrected tip resistance (qt) according to the following expression presented in Robertson et al, 1986: qt = qc + (1-a) • u2 where: qt is the corrected tip resistance qc is the recorded tip resistance u2 is the recorded dynamic pore pressure behind the tip (u2 position) a is the Net Area Ratio for the piezocone (0.8 for ConeTec probes) The sleeve friction (fs) is the frictional force on the sleeve divided by its surface area. As all ConeTec piezocones have equal end area friction sleeves, pore pressure corrections to the sleeve data are not required. The dynamic pore pressure (u) is a measure of the pore pressures generated during cone penetration. To record equilibrium pore pressure, the penetration must be stopped to allow the dynamic pore pressures to stabilize. The rate at which this occurs is predominantly a function of the permeability of the soil and the diameter of the cone. The friction ratio (Rf) is a calculated parameter. It is defined as the ratio of sleeve friction to the tip resistance expressed as a percentage. Generally, saturated cohesive soils have low tip resistance, high CONE PENETRATION TEST friction ratios and generate large excess pore water pressures. Cohesionless soils have higher tip resistances, lower friction ratios and do not generate significant excess pore water pressure. A summary of the CPTu soundings along with test details and individual plots are provided in the appendices. A set of interpretation files were generated for each sounding based on published correlations and are provided in Excel format in the data release folder. Information regarding the interpretation methods used is also included in the data release folder. For additional information on CPTu interpretations, refer to Robertson et al. (1986), Lunne et al. (1997), Robertson (2009), Mayne (2013, 2014) and Mayne and Peuchen (2012). SEISMIC CONE PENETRATION TEST Shear wave velocity testing is performed in conjunction with the piezocone penetration test (SCPTu) in order to collect interval velocities. For some projects seismic compression wave (Vp) velocity is also determined. ConeTec’s piezocone penetrometers are manufactured with a horizontally active geophone (28 hertz) that is rigidly mounted in the body of the cone penetrometer, 0.2 meters behind the cone tip. Shear waves are typically generated by using an impact hammer horizontally striking a beam that is held in place by a normal load. In some instances an auger source or an imbedded impulsive source maybe used for both shear waves and compression waves. The hammer and beam act as a contact trigger that triggers the recording of the seismic wave traces. For impulsive devices an accelerometer trigger may be used. The traces are recorded using an up-hole integrated digital oscilloscope which is part of the SCPTu data acquisition system. An illustration of the shear wave testing configuration is presented in Figure SCPTu-1. Figure SCPTu-1. Illustration of the SCPTu system All testing is performed in accordance to ConeTec’s SCPTu operating procedures. Prior to the start of a SCPTu sounding, the procedures described in the Cone Penetration Test section are followed. In addition, the active axis of the geophone is aligned parallel to the beam (or source) and the horizontal offset between the cone and the source is measured and recorded. Prior to recording seismic waves at each test depth, cone penetration is stopped and the rods are decoupled from the rig to avoid transmission of rig energy down the rods. Multiple wave traces are recorded for quality control purposes. After reviewing wave traces for consistency the cone is pushed to the next test depth (typically one meter intervals or as requested by the client). Figure SCPTu-2 presents an illustration of a SCPTu test. SEISMIC CONE PENETRATION TEST For additional information on seismic cone penetration testing refer to Robertson et.al. (1986). Figure SCPTu-2. Illustration of a seismic cone penetration test Calculation of the interval velocities are performed by visually picking a common feature (e.g. the first characteristic peak, trough, or crossover) on all of the recorded wave sets and taking the difference in ray path divided by the time difference between subsequent features. Ray path is defined as the straight line distance from the seismic source to the geophone, accounting for beam offset, source depth and geophone offset from the cone tip. The average shear wave velocity to a depth of 100 feet (30 meters) (𝑣̅𝑠) has been calculated and provided for all applicable soundings using the following equation presented in ASCE, 2010. 𝑣̅𝑠=∑𝑑𝑖𝑛𝑖=1 ∑𝑑𝑖𝑣𝑠𝑖 𝑛𝑖=1 where: 𝑣̅𝑠 = average shear wave velocity ft/s (m/s) 𝑑𝑖 = the thickness of any layer between 0 and 100 ft (30 m) 𝑣𝑠𝑖 = the shear wave velocity in ft/s (m/s) ∑𝑑𝑖𝑛𝑖=1 = 100 ft (30 m) Average shear wave velocity, 𝑣̅𝑠 is also referenced to Vs100 or Vs30. The layer travel times refers to the travel times propagating in the vertical direction, not the measured travel times from an offset source. Tabular results and SCPTu plots are presented in the relevant appendix. PORE PRESSURE DISSIPATION TEST The cone penetration test is halted at specific depths to carry out pore pressure dissipation (PPD) tests, shown in Figure PPD-1. For each dissipation test the cone and rods are decoupled from the rig and the data acquisition system measures and records the variation of the pore pressure (u) with time (t). Figure PPD-1. Pore pressure dissipation test setup Pore pressure dissipation data can be interpreted to provide estimates of ground water conditions, permeability, consolidation characteristics and soil behavior. The typical shapes of dissipation curves shown in Figure PPD-2 are very useful in assessing soil type, drainage, in situ pore pressure and soil properties. A flat curve that stabilizes quickly is typical of a freely draining sand. Undrained soils such as clays will typically show positive excess pore pressure and have long dissipation times. Dilative soils will often exhibit dynamic pore pressures below equilibrium that then rise over time. Overconsolidated fine-grained soils will often exhibit an initial dilatory response where there is an initial rise in pore pressure before reaching a peak and dissipating. PORE PRESSURE DISSIPATION TEST Figure PPD-2. Pore pressure dissipation curve examples In order to interpret the equilibrium pore pressure (ueq) and the apparent phreatic surface, the pore pressure should be monitored until such time as there is no variation in pore pressure with time as shown for each curve of Figure PPD-2. In fine grained deposits the point at which 100% of the excess pore pressure has dissipated is known as t100. In some cases this can take an excessive amount of time and it may be impractical to take the dissipation to t100. A theoretical analysis of pore pressure dissipations by Teh and Houlsby (1991) showed that a single curve relating degree of dissipation versus theoretical time factor (T*) may be used to calculate the coefficient of consolidation (ch) at various degrees of dissipation resulting in the expression for ch shown below. ch = T*∙a2 ∙√Ir t Where: T* is the dimensionless time factor (Table Time Factor) a is the radius of the cone Ir is the rigidity index t is the time at the degree of consolidation Table Time Factor. T* versus degree of dissipation (Teh and Houlsby, 1991) Degree of Dissipation (%) 20 30 40 50 60 70 80 T* (u2) 0.038 0.078 0.142 0.245 0.439 0.804 1.60 The coefficient of consolidation is typically analyzed using the time (t50) corresponding to a degree of dissipation of 50% (u50). In order to determine t50, dissipation tests must be taken to a pressure less than u50. The u50 value is half way between the initial maximum pore pressure and the equilibrium pore pressure value, known as u100. To estimate u50, both the initial maximum pore pressure and u100 must be known or estimated. Other degrees of dissipations may be considered, particularly for extremely long dissipations. At any specific degree of dissipation the equilibrium pore pressure (u at t100) must be estimated at the depth of interest. The equilibrium value may be determined from one or more sources such as measuring the value directly (u100), estimating it from other dissipations in the same profile, estimating the phreatic surface and assuming hydrostatic conditions, from nearby soundings, from client provided information, from site observations and/or past experience, or from other site instrumentation. PORE PRESSURE DISSIPATION TEST For calculations of ch (Teh and Houlsby, 1991), t50 values are estimated from the corresponding pore pressure dissipation curve and a rigidity index (Ir) is assumed. For curves having an initial dilatory response in which an initial rise in pore pressure occurs before reaching a peak, the relative time from the peak value is used in determining t50. In cases where the time to peak is excessive, t50 values are not calculated. Due to possible inherent uncertainties in estimating Ir, the equilibrium pore pressure and the effect of an initial dilatory response on calculating t50, other methods should be applied to confirm the results for ch. Additional published methods for estimating the coefficient of consolidation from a piezocone test are described in Burns and Mayne (1998, 2002), Jones and Van Zyl (1981), Robertson et al. (1992) and Sully et al. (1999). A summary of the pore pressure dissipation tests and dissipation plots are presented in the relevant appendix.

The 5.94-acre project site comprises eight parcels located at 2740 Jones Road, southeast of the intersection of Interstate 680 and Treat Boulevard. Its PRS location is SW, SW¼, SW¼, Sec. 14, T1N, R2W, Walnut Creek quadrangle (USGS 7.5'-series topographic map). Google Earth imagery shows this flat terrain has been disturbed by prior development. The client proposes constructing 19 three-story townhome condominium buildings on this site. Geologic Mapping As shown here on part of the geologic map of Dibblee and Minch (2005), both the surface of the project site (outline at center) and half-mile search area (larger dashed black outline) consist solely of Holocene alluvium (Qa). Just outside the search area are the late to middle Miocene Monterey Formation shale (Tmc) and sandstone (Tms), and the Paleocene Martinez Formation (Tmz). Holocene deposits are too young to be fossiliferous, while the two Tertiary units are of marine origin and potentially fossiliferous. Paleontological Records Search The paleontological records search of the UCMP database initially focused on the Miocene and Martinez formations in Paleontological Records Search: Oak Road Project (2648.0017) K.L. Finger 2 Contra Costa County, even though either is unlikely to be present in the shallow subsurface of the project site. The results for the Monterey Formation are one vertebrate locality (V4616, Tormey B), which yielded a Barstovian-aged (upper Miocene) cetacean vertebra. In addition, there are three other Barstovian localities in unidentified geological units, and their yield consists of a pelvis fragment of Desmostylus (extinct marine hippo-like mammal), a Carcarocles megalodon (megalodon shark) tooth, and ribs of an unidentified marine mammal. Of these four Barstovian localities, the closest to the project site is V68104 (Bellamy) in Pleasant Hill, mapped at the north- northwest edge of the search area and which yielded the megalodon tooth, while the other three localities are about 15 miles to the northwest. The recorded location of V68104, however, is questionable because the area is mapped as Holocene, the geologic map shows the Monterey Formation nearly one mile to the southeast, and there is no indication that the tooth was found in the subsurface. For the Martinez Formation, there are three vertebrate localities, all approximately five miles east of Mount Diablo, and each yielded a single element of fish. No plant localities are recorded for either the Monterey or Martinez formations in the County. Paleontological Assessment and Mitigation Recommendations A preconstruction paleontological walkover survey of the proposed Oak Road project site is not recommended because its surface is flat and disturbed. I also do not recommend paleontological monitoring of project-related earth-disturbing construction activities because the surficial deposits are Holocene, and the nearest older deposits are mapped nearly a mile away. Hence, it is highly unlikely that any significant paleontological resources will be encountered during project-related construction activities. This report therefore concludes the paleontological mitigation for this project in accordance with CEQA guidelines. Sincerely, Reference Cited Dibblee, T.W., Jr., and Minch, J.A., 2005.

(Roux) has performed a Phase I Environmental Site Assessment (ESA) and a Focused Phase II environmental subsurface Investigation at 2740 Jones Road, Walnut Creek, California (Property). This Phase I ESA was performed on behalf of SummerHill Homes, Inc. (User). Roux understands that the User plans to redevelop the Property for residential use. The Property is located at 2740 Jones Road in a mixed residential and commercial area to the east of Interstate 680 in Walnut Creek, California. The area of the Property is approximately 5.72 acres and is currently occupied by a private elementary school. The associated Assessor Parcel Numbers (APNs) are provided in the table below. Parcel Number Associated Address 172-012-001-1 No Address 172-012-007-8 2770 Jones Road 172-012-008-6 2747 Oak Road and 2740 Jones Road 172-012-020-1 2740 Jones Road 172-012-021-9 2731 Oak Road and 2740 Jones Road 172-012-023-5 2751 Oak Road and 2740 Jones Road 172-012-025-0 2776 Oak Road and 2740 Jones Road 172-012-026-8 2771 Oak Road The Property was mostly utilized for orchards between at least 1939 and the 1960s, when several of the current buildings associated with Palmer School for Boys and Girls were developed. However, the school had been running in some form at the Property since the 1940s. The school was closed in June 2020. The Property contains three irrigation wells. One of the wells is located in the school courtyard in the southern portion of the Property, reportedly set at a depth of approximately 60 feet below ground surface (bgs). The remaining two irrigation wells are located along the northern boundary of the Property behind the buildings at 2747 Oak Road and 2771 Oak Road and are reportedly not active and the depths are unknown. See Figure 2 for the location of the irrigation wells. The Phase I ESA was performed to identify recognized environmental conditions (RECs), controlled recognized environmental conditions (CRECs), and/or historical recognized environmental conditions (HRECs) at the Property, indicating past, current, or material threats of the release of hazardous materials or petroleum hydrocarbons to the Property’s soil, groundwater, or surface water. The ESA was conducted by investigating past Property uses, reviewing the results of a search of environmental databases, reviewing records at relevant government agencies, and performing a Property reconnaissance. One REC was identified at the Property: • Approximately 25 years ago, a 50-gallon UST thought to have contained gasoline was reportedly removed behind the building at 2771 Oak Road. No staining or odors were observed in the underlying soil, but the UST was removed without proper oversight and no soil samples were collected below the UST. Although no indication of a release has been reported at the Property and the tank was relatively small, it is possible that releases from the gasoline UST could have historically occurred, which is considered a REC. 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | iv Two environmental concerns were identified at the Property that do not rise to the level of a REC but are considered business environmental risks (BER): 1. The Property was utilized for orchards between at least 1939 and the 1960s. Potential residual pesticide impacts in shallow soils are considered a BER; and 2. The Property contains three irrigation wells. Since these wells would need to be properly decommissioned prior to redevelopment, they are considered a BER. Roux conducted environmental subsurface investigations to assess the REC and BER 1 identified in the Phase I ESA between August and December 2020. A total of nine borings (RB-1 through RB-9) were advanced at the Site and soil, soil vapor, and groundwater samples were collected. The sampling locations are shown on Figure 3. The sampling results were compared to San Francisco Bay Regional Water Quality Control Board Residential Environmental Screening Levels (ESLs) as well as the San Francisco Bay Area natural background concentrations in soil, specifically for arsenic. The soil sampling results indicate that all detections were below the applicable Residential ESLs and natural background levels, including samples collected from RB-2, RB-6, and RB-9 based on elevated PID readings during logging. Benzene in soil vapor from all five soil vapor probes (RB -2 and RB-6 through RB-9) exceeded the RWQCB Residential ESL of 3.2 micrograms per cubic meter (µg/m³)at concentrations ranging from 6.9 µg/m³ (RB - 9 SV) to 16 µg/m³ (RB-7-SV). However, these concentrations are relatively low and soil oxygen concentrations in soil vapor indicate that conditions in soil in the vicinity of RB -2 are favorable to the natural degradation of petroleum hydrocarbons. In addition, the groundwater investigation confirmed that no benzene source exists in groundwater in the vicinity of RB-2. As a precautionary measure, soil aeration will be utilized as the mitigation measure to address the benzene detected in soil vapor. Soil aeration consists of spreading excavated soil on the ground in an approximately 18-inch-thick layer. Mixing of the soil (tilling) will be performed regularly to maintain aerobic conditions (presence of oxygen). The soil will be thoroughly tilled using equipment s uch as a Terex RS600 Reclaimer/Stabilizer. The proposed excavation area is approximately 30 feet long by 20 feet wide and 6 feet deep with a total volume of 135 cubic yards. A total of six tilling passes will be performed. Soil and soil vapor sampling will be performed at the end of tilling operations prior to backfill. Soil vapor samples will also be collected from compacted backfill to confirm no soil vapor impacts in the soils. If soil vapor exceedances are identified after soil excavation and aerati on, a Soil Management Plan will be prepared and forwarded to an appropriate environmental agency for disposition. This Focused Phase II has adequately investigated the scope of the REC and BER -1. The sampling results for pesticides eliminates BER-1 as a potential risk at the Site. In addition, the mitigation measure will reduce the risk of benzene vapor to below a level of significance. 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 1 1. Introduction At the request of SummerHill Homes, Inc. (User), Roux Associates, Inc. (Roux) performed a Phase I Environmental Site Assessment (ESA) and a Focused Phase II environmental subsurface investigation (Focused Phase II) at 2740 Jones Road, California (Property). The Property location is shown in Figure 1. The Phase I ESA was conducted in accordance with the scope of work presented in the proposal submitted by Roux on July 20, 2020 and in general accordance with the American Society of Testing and Materials’ (ASTM) International Standard Practice E1527-13 (Standard Practice for Environmental Site Assessments), consistent with the United States Environmental Protection Agency (USEPA) Standards and Practices for All Appropriate Inquiries (AAI) Rule (40 CFR Part 312, Standards and Practices for All Appropriate Inquiries; Final Rule1). The preamble for the AAI Rule states: In today's final rule, EPA is referencing the standards and practices developed by ASTM International and known as Standard E1527-05 (entitled “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process'') and recognizing the E1527-05 standard as consistent with today's final rule . The Agency determined that this voluntary consensus standard is consistent with today's final rule and is compliant with the statutory criteria for all appropriate inquiries . Persons conducting all appropriate inquiries may use the procedures included in the ASTM E1527-05 standard to comply with today's final rule.2 This AAI Rule was subsequently amended in 2013, as indicated in the following “Background”: With today's action, EPA is establishing that parties seeking liability relief under CERCLA's landowner liability protections, as well as recipients of brownfields grants for conducting site assessments, will be considered to have met the standards and practices for all appropriate inquiries, as set forth in the Brownfields Amendments to CERCLA and 40 CFR Part 312, if such parties follow the procedures provided in the ASTM E1527-13 “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process.” EPA made this determination based upon the Agency's finding that the ASTM E1527-13 standard is compliant with the All Appropriate Inquiries Rule. Therefore, parties conducting all appropriate inquiries may use the procedures in the newly issued ASTM E1527-13 standard when conducting all appropriate inquiries.3 The purpose of the Phase I ESA was to identify, to the extent feasible, Recognized Environmental Conditions (RECs) in connection with the Property. ASTM Standard Practice E1527-13 defines RECs as: …the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not recognized environmental conditions. ASTM Standard Practice E1527-13 provides that identified RECs can be evaluated and classified into Controlled Recognized Environmental Conditions (CRECs) or Historical Recognized Environmental 1 Final Rule and information available at www.epa.gov/swerosps/bf/regneg.htm#final_rule, and https://federalregister.gov/a/2013-31112. 2 Federal Register: November 1, 2005 (Volume 70, Number 210), page 66081. 3 Federal Register: December 30, 2013 (Volume 78, Number 250). 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 2 Conditions (HRECs) based on the following definitions. ASTM Standard Practice E1527-13 defines a CREC as: …a recognized environmental condition resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority (for example, as evidenced by the issuance of a no furthe r action letter or equivalent, or meeting risk-based criteria established by regulatory authority), with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls (for example, property use res trictions, activity and use limitations, institutional controls, or engineering controls). ASTM Standard Practice E1527-13 defines a HREC as: …a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls). In order to assess the potential for RECs associated with the Property, Roux utilized a variety of information sources to perform the Phase I ESA, including a radial information search from federal, state, and local regulatory agency databases and readily available information from the following sources: Property owner, historical aerial photographs, historical topographic maps, and city directories. Also, Freedom of Information Act (FOIA)/public records request responses from federal, state, and local regulatory agencies were conducted. The historical research and questionnaire were conducted in order to develop an understanding of the following: • Current and past uses of the Property; • Current and past uses of hazardous substances and/or petroleum at the Property, if any; • Waste management and disposal practices that might have potentially caused releases or threatened releases of hazardous substances and/or petroleum products at the Property; • Current and past corrective actions and response activities undertaken to address past and ongoing releases of hazardous substances and/or petroleum products at the Property, if any; • The existence of any engineering and/or institutional controls recorded for the Property; and, • Current and past uses of adjoining properties that could have resulted in releases or threatened releases of hazardous substances and/or petroleum products to the Property. Roux’s Principal Engineer Angela Liang Cutting, Ph.D., P.E. and Staff Geologist Katherine Grellman served as the Environmental Professionals who conducted the Phase I ESA. Dr. Cutting possesses sufficient specific education, training, and experience to exercise professional judgment to de velop opinions and conclusions regarding conditions indicative of releases or threatened releases, as defined in 40 CFR §312.1(c) on, at, in, or to a Property, sufficient to meet the objectives and performance factors in 40 CFR §312.20(e) and (f). 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 3 2.

The objective of the reconnaissance was to check for visual evidence of past or present use or storage of hazardous materials that could potentially affect the soil, groundwater quality, and soil vapor at the Property. Photographs taken during the Property reconnaissance are attached (Appendix G). Roux was accompanied during the Property reconnaissance by Sam Mendes, the facilities manager. Mr. Mendes was available to answer questions during the Property reconnaissance. The Property consists of a former elementary school and several buildings. The former school includes classrooms, an auditorium, a front office, a paved courtyard, a grass field, tennis courts, basketball courts playgrounds, a swimming pool, and associated parking lots and landscaping areas. Multiple storage sheds were observed. The classrooms, located in the southern portion of the Property, are generally empty or used as storage rooms for conventional classroom materials including art supplies, desks, chairs, extension cords, books, etc. Situated outside of the classrooms are rows of lockers, bathrooms, and a janitorial closet with a boiler and conventional janitorial cleaning chemicals. A landscaping area behind the classrooms along the southern boundary of the Property includes planter boxes, storm drain lines, and power boxes, and a partially uncovered pipe, was observed, which appears to be related to storm drainage. In the southeast corner of the Property is a two-story auditorium used as a storage area containing a kitchen, stage, water heater, and empty storage rooms on the second floor. The following was observed in the paved courtyard/parking area in the southeast portion of the Property: several maintenance sheds with spray-paint, conventional janitorial and gardening supplies, and small bottles of Home Defense insect killer and Roundup. Across the courtyard to the west is a two-story building utilized as an office and storage space similar to the other storage areas. Two small bottles of Spectracide insect killers were identified in a storage room upstairs. Buildings are in the northern portion of the Property. Buildings at 2747 Oak Road Units 1 and 2 included several rooms and a garage. 2771 Oak Road and 2747 Oak Road Units 3, 4, and 5 are all utilized as storage space similar to other storage units on the Property. Observed chemicals were all small containers of conventional cleaning supplies. Several storage units are located outside of the buildings containing building materials, office supplies, furniture, etc. East of the buildings is an unpaved lot and the location of a former trash enclosure that was removed around June 2020. The trash enclosure was located on a paved driveway of the Property to the west of Jones Road. Mr. Mendes pointed out the location of a former 50-gallon UST in the northern portion of the Property behind the building at 2771 Oak Road. See Figure 2 for the suspected location of the UST. The area had subsequently been repaved and therefore did not maintain any surface features. According to Mr. Mendes, the UST was removed approximately 25 years ago, and the age and original use of the UST was unknown. Based on the relatively small size of the UST, it had been removed without regulatory oversight. According to Mr. Mendes, no staining or odors were observed in the underlying soil once the UST was removed. Although the UST was small and no impacts were reportedly observed, the UST was removed without proper oversight and no soil samples were collected below the UST. This is considered a REC. 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 18 6.1 Utilities Electrical and gas utilities are provided to the Property by Pacific Gas and Electric (PG&E). Water is provided by the City of Walnut Creek. 6.2 Hazardous Substances Roux did not observe the presence of any hazardous substances other than small containers of conventional cleaning supplies and insecticides. 6.3 Polychlorinated Biphenyls Several transformers were observed outside the Property on utility poles along Oak Road; however, they appeared to be in good condition and are too high to pose a leaking risk to the soil or groundwater. 6.4 Staining and Stressed Vegetation No staining or stressed vegetation was observed at the Property. 6.5 Drains and Sumps Several drains were located within bathroom spaces and outside in the paved courtyard area ; however, no staining was observed around the drains. 6.6 Solid Waste According to the facility manager, garbage collection services ceased at the Property around June 2020 following the closure of the school. Conventional waste is collected from the residences. 6.7 Wastewater No wastewater processes were observed during Property reconnaissance. 6.8 Wells Three irrigation wells were observed at the Property. One of the wells is located in the school courtyard in the southern portion of the Property, reportedly set at a depth of approximately 60 feet bgs, according to the facility manager. Accompanying the well is a filter and a pressure tank. The remaining two irrigation wells, are located along the northern boundary of the Property behind the buildings at 2747 Oak Road and 2771 Oak Road, and are reportedly not active and the depths are unknown. The well behind 2771 Oak Road is uncovered. These wells would need to be properly abandoned prior to redevelopment and are therefore considered a Business Environmental Risk. See Figure 2 for the location of the irrigation wells. 6.9 Out-of-Scope Services No out-of-scope services were provided. 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 19 7.Interviews and User-Provided Information To complete this Phase I ESA, Roux requested an interview and questionnaire from the User. 7.1 Interviews During the Property reconnaissance activities on July 31, 2020, Roux was able to conduct an interview with Sam Mendes, the facility manager. Additionally, Mr. Mendes filled out an owner questionnaire, which is discussed here and provided in Appendix H. According to Mr. Mendes Palmer School, a private elementary school, operated at the Property for 80 years until its closure around June 2020. Since then, most of the buildings have been utilized as storage space for school supplies and equipment. Prior to school operations, the Property was used for orchards. According to Mr. Mendes, the 50-gallon UST was removed around 25 years ago without regulatory oversight or confirmation sampling. The age of the UST and its historical use were unknown but it is believed to have previously contained gasoline. According to Mr. Mendes it was empty when it was removed, and no staining or odors were observed in the underlying soil. Mr. Mendes does not know of any environmental concerns at the Property. Additionally, Mr. Mendes did not know what the 2012 HWTS listing for the Property, discussed in Sections 5.1.1 and 5.2, was related to. 7.2 User Questionnaire Roux received a completed questionnaire from the User (Appendix H) on July 27, 2020. According to the questionnaire, the Property was initially developed in the 1940s. The User is unaware of any environmental liens, land use limitations, engineering controls, cleanups, or chemical releases at the Property. The User believes the purchase price for the Property reasonably reflects the fair market value and does not have specialized knowledge of the Property. 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 20 8. Phase I ESA Conclusions and Recommendations Roux has performed a Phase I ESA at 2740 Jones Road, California. This ESA was performed on behalf of the User and is intended to define the historical uses of the Property and identify any potential RECs for the Property, as defined by ASTM International Standard Practice E1527-13. This Phase I ESA was performed to identify RECs, CRECs, and/or HRECs at the Property, indicating past, current, or material threats of the release of hazardous materials or petroleum hydrocarbons to the Property’s soil, groundwater, or surface water. The Phase I ESA was conducted by investigating past Property uses, reviewing the results of a search of environmental databases, reviewing records at relevant government agencies, and performing a Property reconnaissance. One REC was identified at the Property: 1. Approximately 25 years ago, a 50-gallon UST thought to have contained gasoline was reportedly removed behind the building at 2771 Oak Road. No staining or odors were observed in the underlying soil, but the UST was removed without proper oversight and no soil samp les were collected below the UST. Although no indication of a release has been reported at the Property and the tank was relatively small, it is possible that releases from the gasoline UST could have historically occurred, which is considered a REC. Two environmental concerns were identified at the Property that do not rise to the level of a REC but are considered as a business environmental risk (BER): 1. The Property was utilized for orchards between at least 1939 and the 1960s. Potential residual pesticide impacts in shallow soils are considered a BER; and 2. The Property contains three irrigation wells. Since these wells would need to be properly decommissioned prior to redevelopment, they are considered a BER. A Focused Phase II was conducted to assess the REC and BER 1. 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 21 9. Focused Phase II Roux conducted environmental subsurface investigations to assess the REC and BER 1 identified in the Phase I ESA between August and December 2020. The details of these investigations are described below. 9.1 Pre-Field Activities Prior to intrusive work at the Property, Roux prepared a Property-specific Health and Safety Plan. Drilling permits were obtained from Contra Costa County Environmental Health Division. Roux marked the proposed boring locations with white paint and notified Underground Service Alert of intended subsurface work at least two business days prior to drilling. Private geophysical services and utility locating firms, Subtronic Corporation, of Martinez, California for the first mobilization, and Ground Penetrating Radar Services Inc., of Manteca, California for the second mobilization were retained to assess the location and depth of utilities near each boring location at the Property. 9.2 Boring Advancement On August 14, 2020, under the direction of Roux, PeneCore Drilling (PeneCore) of Woodland, California (C 57 License # 906899) advanced five soil borings (RB -1 through RB-5) to 3 feet below ground surface (bgs) using a hand auger in order to collect soil samples. RB-2 was additionally advanced from 3 to 5 feet bgs using a direct push technology rig and converted into a temporary 5-foot soil vapor probe. RB-2 was continuously logged to record lithological differences in accordance with the Unified Soil Classification System. All soils were field screened with a photoionization detector (PID). Based on an elevated benzene concentration in the soil vapor sample collected from RB -2 in the first round of sampling, an additional mobilization occurred. On September 15, 2020, under the directio n of Roux, Environmental Control Associates Drilling (ECA) of Aptos, California (C-57 License # 695970) advanced four soil borings (RB-6 through RB-9) as step-outs to RB-2. Each location was advanced to 5 feet bgs and converted into a 5-foot temporary soil vapor probe. Soil in each boring was logged and screened as discussed above. Due to a laboratory malfunction resulting in a loss of the samples discussed above, another mobilization was needed. On October 7, 2020, under the direction of Roux, ECA over-drilled the abandoned RB-6 through RB-9 locations using a direct push technology rig and reinstalled temporary 5-foot soil vapor probes at each location. Since no new soil was removed, no soil logging occurred during the October mobilization. Based on the soil vapor sampling results, groundwater sampling was conducted in the vicinity of boring RB -2. On December 15, 2020. Under the direction of Roux, ECA advanced one soil boring using a direct push technology rig for a grab groundwater sample. Boring locations are presented in Figure 3 and boring logs are provided in Appendix J. 9.3 Soil Sampling To assess if shallow soil has been impacted by historical agricultural use, soil samples were collected from borings RB-1 through RB-5. Samples were collected at 1 and 3 feet bgs from each boring location into laboratory-provided soil jars. During headspace analysis, elevated PID readings were observed at RB -2. 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 22 Therefore, an additional sample was collected at 5 feet bgs from RB 2, corresponding to the depth of the soil vapor sample collected from RB-2. Samples at 1 foot bgs were analyzed for the following: • CAM 17 metals by United States Environmental Protection Agency (EPA) Method 6000/7000 series; and • Organochlorinated pesticides (OCPs) by EPA Method 8081A. Samples at 3 feet bgs were placed on hold, pending the results of the 1-foot samples. Additionally, the 5-foot sample from RB-2 (RB-2-5) was analyzed for the following: • Volatile organic compounds (VOCs) and total petroleum hydrocarbons (TPH) as gasoline (TPH-g) by EPA Method 8260B; and • TPH as diesel (TPH-d) and motor oil (TPH-mo) by EPA Method 8015B. All soil samples were appropriately sealed, labelled, stored on ice, and transported by courier under chain of custody to McCampbell Analytical, Inc. of Pittsburg, California, a California-certified laboratory (McCampbell). During the second mobilization, elevated PID readings were observed in multiple borings (Attachment 1). Therefore, RB-6 and RB-9 were selected for soil sampling and samples were collected from each location at 5 feet bgs, corresponding to the depth of the soil vapor probes (RB -6-5 and RB-9-5), and analyzed for the following analyses: • VOCs and TPH-g by EPA Method 8260B; and • TPH-d and TPH-mo by EPA Method 8015B. These soil samples were transported to McCampbell with the same methods discussed above. 9.4 Temporary Soil Vapor Probe Installation To determine if soil vapor beneath the Property has been impacted in the vicinity of the former 50 -gallon gasoline UST, a temporary soil vapor probe was installed at 5 feet bgs at RB-2. During the second mobilization, temporary soil vapor probes were installed at 5 feet bgs in RB-6 through RB 9 to delineate a benzene exceedance at RB-2. During the third mobilization, RB-6 through RB-9, which had been abandoned, were overdrilled with a direct push technology rig and temporary soil vapor probes were reinstalled. The temporary 5-foot soil vapor probes were installed as follows: A 12-inch sand pack was placed from 4 to 5 feet bgs, surrounding the probe tip (at 4.5 feet bgs) midway in the sand pack to minimize the disruption of airflow to the sampling tip. Twelve inches of dry granular bentonite was placed above the sand from 3 to 4 feet bgs. A final layer of hydrated bentonite was installed immediately above the dry granular bentonite to the surface. Each well’s tubing was capped with a gas-tight fitting. 9.5 Soil Vapor Sampling To assess if soil vapor beneath the Property has been impacted by either historic site use or impacts migrating onsite, soil vapor samples were collected from the 5-foot soil vapor probes RB-2 and RB-6 through RB-9. RB-2 was sampled on August 14, 2020, during the first mobilization, at least 2 hours following soil vapor probe installation. RB-6 through RB-9 were sampled on September 17, 2020, at least 48 hours following soil vapor probe installed. All samples were collected in laboratory-certified Summa canisters. Prior to sample collection, approximately three well volumes were purged from the sample tubing using a “purge” 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 23 Summa canister. Purging activities were conducted at the same flow rate used for soil vapor sample collection (approximately 150 milliliters per minute). During sampling, each Summa canister was enclosed in a shroud and helium introduced into the shroud at a minimum of 20 percent (%) by volume, to be used as a tracer gas to confirm the presence or absence of a significant leak during sampling. The collected soil vapor samples were analyzed for the following: • VOCs by EPA Method TO-15; • TPH-g by EPA Method TO-3; and • Oxygen and helium (tracer gas) content by the American Society for Testing Materials (ASTM) D 1946. All soil vapor samples were appropriately sealed, labelled, and transported by courier under chain of custody to California-certified laboratories. The sample from RB-2 was transported to Enthalpy Analytical of Berkeley, California (Enthalpy) and the samples from RB-6 through RB-9 were transported to K Prime Inc of Santa Rosa, California (K Prime). Due to a nearby fire that caused power outages during analysis, K Prime was unable to retrieve data from the soil vapor samples collected from RB-6 through RB-9. Therefore, Roux’s third mobilization to the Site was for the purpose of collecting an additional set of samples from RB-6 through RB-9. Soil vapor samples were collected from RB-6 through RB-9 on October 8, 2020, as discussed above and transported under chain of custody to Enthalpy. 9.6 Grab Groundwater Sampling To assess if groundwater is a potential source for onsite vapor impacts, one boring was advanced to first encountered groundwater in the vicinity of RB-2. Temporary well casing with a slotted screen was inserted into the boring. A grab groundwater sample was collected using the low-flow method and analyzed for the following: • TPH-g and VOCs by EPA Method 8260; and • TPH as diesel (TPH-d) and motor oil (TPH-mo) by EPA Method 8015. 9.7 Boring Abandonment Following sampling activities, all soil borings were backfilled with grout to just below the surface and patched at the surface to match the surrounding ground cover. The temporary soil vapor probes were abandoned by completely removing the tubing, removing some of th e hydrated bentonite, backfilling the void space with neat cement grout, and patching the surface to match the surrounding ground cover. 9.8 Investigation-Derived Waste (IDW) One 55-gallon Department of Transportation (DOT) steel drum was placed onsite for soil cuttings. The drum was properly sealed and labelled at the end of investigation activities. Following the results of the waste profiling analyses, the drum will be removed from the Property and transported to an appropriate disposal facility. 9.9 Results Soil and soil vapor analytical results are presented in Tables 1 through 4. The complete analytical laboratory reports are included in Attachment 2. 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 24 9.9.1 Lithologic Results Based on the results of this investigation, the Site is underlain predominantly by clay with varying amounts of silt, sand, and gravel to the total explored depth of 5 feet bgs. In the vicinity of RB-2 and RB-6 through RB -9, there is approximately 1 foot of silty sand from the surface, presumed to be fill material. Groundwater was not encountered during this investigation. Boring logs are provided in Attachment 1. 9.9.2 Soil Sampling Results Concentrations detected in soil were compared to RWQ CB February 2019 Residential Soil Direct Exposure Environmental Screening Levels (ESLs) as well as the San Francisco Bay Area natural background concentrations in soil , specifically for arsenic, with the following results: • No pesticides detections exceeded their applicable Residential ESLs in any soil samples; • All metals except arsenic were detected at concentrations below their applicable Residential ESLs. Arsenic concentrations were below the natural background concentration of 11 milligrams per kilogram (mg/kg); and • No TPH or VOC detections exceeded their applicable Residential ESLs. Soil analytical results were also compared to hazardous waste criteria. Based on the preliminary results chromium was additionally analyzed in RB-1-1, RB-3-1, and RB-5-1 for the Soluble Threshold Limit Concentration (STLC) hazardous waste criteria limit, and lead was analyzed for the STLC in RB -4-1. All samples were below the STLC of 5.0 milligrams per liter. Soil analytical results are summarized in Tables 1 through 3. 9.9.3 Soil Vapor Analytical Results Concentrations detected in soil vapor samples were compared to RWQCB February 2019 Residential Vapor Intrusion ESLs. The results are summarized below: • Benzene was detected above the Residential ESL of 3.2 micrograms per cubic meter (µg/m³) in all soil vapor samples (RB-2-SV and RB-6-SV through RB-9-SV) at concentrations ranging from 6.9 µg/m³ (RB-9-SV) to 16 µg/m³ (RB-7-SV); • No other VOCs were detected above their respective ESLs; • Oxygen was detected at concentrations ranging from 17percent by volume (%v) to 19 %v, indicating that conditions in soil in the vicinity of RB-2 and RB-6 through RB-9 are favorable to the natural degradation of petroleum hydrocarbons; and • Helium was not detected in any of the samples, indicating that there were no significant leaks during sample collection. Soil vapor analytical results are summarized in Table 4. 9.9.4 Groundwater Sampling Results Benzene was detected at an estimated concentration of 0.049 micrograms per liter (g/L), below the RWQCB Vapor Intrusion ESL of 0.42 g/L. No other VOCs were detected in the grab groundwater sample. 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 25 9.10 Focused Phase II Summary The soil results indicate that all detections were below the applicable Residential ESLs and natural background levels, including samples collected from RB-2, RB-6, and RB-9 based on elevated PID readings during logging. Based on the results of the additional investigation, benzene in soil vapor from all five soil vapor probes (RB - 2 and RB-6 through RB-9) exceeded the RWQCB Residential ESL of 3.2 µg/m³ at concentrations ranging from 6.9 µg/m³ (RB-9-SV) to 16 µg/m³ (RB-7-SV). However, these concentrations are relatively low and oxygen concentrations in soil vapor indicate that conditions in soil in the vicinity of RB-2 are favorable to the natural degradation of petroleum hydrocarbons. In addition, the groundwater investigation confirmed that no benzene source exists in groundwater in the vicinity of RB-2. 9.11 Mitigation Measures As a precautionary measure, soil aeration will be utilized as the mitigation measure to address the benzene detected in soil vapor. Soil aeration consists of spreading excavated soil on the ground in an approximately 18-inch-thick layer. Mixing of the soil (tilling) will be performed regularly to maintain aerobic conditions (presence of oxygen). The soil will be thoroughly tilled using equipment such as a Terex RS600 Reclaimer/Stabilizer. The proposed excavation area is approximately 30 feet long by 20 feet wide and 6 feet deep with a total volume of 135 cubic yards. A total of six tilling passes will be performed. During the tilling operation, air quality monitoring will be performed 3 inches above the soils and also in the breathing zone with a PID. Dust control measures will be conducted, and dust monitoring will be performed in the perimeter of the Site boundary. In addition, stormwater Best Management Practices (BMPs) will be implemented, if applicable. Soil and soil vapor sampling will be performed at the end of tilling operations prior to backfill. Soil vapor samples will also be collected from compacted backfill to confirm no soil vapor impacts in the soils. If soil vapor exceedances are identified after soil excavation and aeration, a Soil Management Plan will be prepared and forwarded to an appropriate environmental agency for disposition. 9.12 Conclusions This Focused Phase II has adequately investigated the scope of the REC and BER-1. The sampling results for pesticides eliminates BER-1 as a potential risk at the Site. The mitigation measure described in Section 9.11 will reduce the risk of benzene vapor to below a level of significance. 2965.0013S100/R Phase I ESA and Focused Phase II Report | ROUX | 26 10.

EXECUTIVE SUMMARY TC6133154.2s EXECUTIVE SUMMARY 10 Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property. Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed. Sites listed in bold italics are in multiple databases. Unmappable (orphan) sites are not considered in the foregoing analysis. STANDARD ENVIRONMENTAL RECORDS Federal RCRA generators list RCRA-SQG: RCRAInfo is EPA’s comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month. A review of the RCRA-SQG list, as provided by EDR, and dated 03/23/2020 has revealed that there are 11 RCRA-SQG sites within approximately 0.25 miles of the target property.

The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Very small quantity generators (VSQGs) generate less than 100 kg of hazardous waste, or less than 1 kg of acutely hazardous waste per month. A review of the RCRA-VSQG list, as provided by EDR, and dated 03/23/2020 has revealed that there is 1 RCRA-VSQG site within approximately 0.25 miles of the target property.

The database includes the following site types: Federal Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information that was available in CalSites, and provides additional site information, including, but not limited to, identification of formerly-contaminated properties that have been released for reuse, properties where environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk characterization information that is used to assess potential impacts to public health and the environment at contaminated sites. A review of the ENVIROSTOR list, as provided by EDR, and dated 04/27/2020 has revealed that there are 5 ENVIROSTOR sites within approximately 1 mile of the target property.

EXECUTIVE SUMMARY TC6133154.2s EXECUTIVE SUMMARY 10 Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property. Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed. Sites listed in bold italics are in multiple databases. Unmappable (orphan) sites are not considered in the foregoing analysis. STANDARD ENVIRONMENTAL RECORDS Federal RCRA generators list RCRA-SQG: RCRAInfo is EPA’s comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month. A review of the RCRA-SQG list, as provided by EDR, and dated 03/23/2020 has revealed that there are 11 RCRA-SQG sites within approximately 0.25 miles of the target property.

The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Very small quantity generators (VSQGs) generate less than 100 kg of hazardous waste, or less than 1 kg of acutely hazardous waste per month. A review of the RCRA-VSQG list, as provided by EDR, and dated 03/23/2020 has revealed that there is 1 RCRA-VSQG site within approximately 0.25 miles of the target property.

The database includes the following site types: Federal Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information that was available in CalSites, and provides additional site information, including, but not limited to, identification of formerly-contaminated properties that have been released for reuse, properties where environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk characterization information that is used to assess potential impacts to public health and the environment at contaminated sites. A review of the ENVIROSTOR list, as provided by EDR, and dated 04/27/2020 has revealed that there are 5 ENVIROSTOR sites within approximately 1 mile of the target property.

EDR’s review was limited to those categories of sources that might, in EDR’s opinion, include gas station/filling station/service station establishments. The categories reviewed included, but were not limited to gas, gas station, gasoline station, filling station, auto, automobile repair, auto service station, service station, etc. This database falls within a category of information EDR classifies as "High Risk Historical Records", or HRHR. EDR’s HRHR effort presents unique and sometimes proprietary data about past sites and operations that typically create environmental concerns, but may not show up in current government records searches. A review of the EDR Hist Auto list, as provided by EDR, has revealed that there is 1 EDR Hist Auto site within approximately 0.125 miles of the target property.

The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

Manufactured gas sites were used in the United States from the 1800’s to 1950’s to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

Please confirm PD zoning is the appropriate process for this project considering the various zoning designations on the site and that the PD zoning will determine all zoning standards including guest parking at a ratio of less than .25 due to proximity of the BART Station. It is our belief that the current zoning designations are not conducive for the development of this assemblage of properties. Please confirm General Plan and Zoning conformance. 2. The M-29 zoning district is consistent with the General Plan, but the height limit of 30’ is not consistent with the M-29 density range. We assume this can be modified through the PD process, please confirm. 3. How does Staff determine the efficacy of discretionary zoning related to the PD zoning process? 4. Does Preliminary Application review process include public or neighborhood noticing? 5. Explain Preliminary Application submittal process, minimum requirements and timing due to short 45-day feasibility period. Please identify any design, architectural issues and required design guidelines. Please advise the length of staff review process. 6. What are the steps needed including all applications necessary to secure entitlements including CEQA, zoning, design review, tree removal, grading, demolition permits and subdivision approval? 7. Typical timing for entitlements approval? What are timelines for staff review of submittals, 30 days for 1st submittal? 2nd and 3rd Subsequent submittals? 8. Do all entitlements go to Planning Commission only including CEQA or first Planning Commission and then Board of Supervisors. 9. Board or Planning Commission meeting vacations/interruptions? 10. CEQA requirements (MND or EIR)? How prepared. Accept info from applicant’s tree report, AQ, noise, cultural/archeology, historical, geotech, phase 1 and 2 environmental and biological? 11. Walnut Creek sphere of influence (pre-zoned XX). Implications/limitations? 12. Tree Removal process? Part of entitlement process? How are Heritage Trees removal permits acquired? 13. Any historical resources identified on the site? 14. We understand that City of Walnut Creek will not formally be involved with this application? Please confirm. We are not anticipating this property will be annexed into the City of Walnut Creek. 15. The Inclusionary Housing Ordinance provides that project may pay in-lieu BMR fees rather than provide BMR units on site. Are there any other means of compliance? 16. Please provide contact persons responsible for Planning, Public Works, Building Dept and Fire Dept to assist in determining comprehensive entitlement and development fees including but not limited planning, building, subdivision, inclusionary, park-in-lieu and all applicable engineering and fire fees along with any other pertinent requirements i.e.: propane limitations on decks? 17. Please provide a list of fees/costs that are subject to T&M charges. 18. Any political or school closure issues with Walnut Creek, neighborhood groups, others? 19. Any recent changes to zoning or development regulations? Any pending? 20. What level of review would the City of Walnut Creek be involved with this application? We anticipate the County would be the lead agency from Pre-App thru entitlement, site improvements and building permit review process. We are not anticipating this property will be annexed into the City of Walnut Creek. 21. Any suggestions? Civil Questions 1. We anticipate no right of way dedication is required on Oak Road or Jones Road. 2. We anticipate the internal fire access roadways will be 26’ curb to curb and the alleyways (between buildings) would be 20’ wide with rolled curb & gutters. 3. As a part of the Pre-App review, we assume the County would solicit comment/input from the County Fire Department. Would the applicant need to meet with the County Fire separately for their input on roadway widths and access requirements? 4. We anticipate all internal roadways and drainage facilities will be privately owned and maintained by HOA. 5. We anticipate the proposed location of driveways on Oak Road and Jones Road are acceptable. 6. We assume the existing overhead utility lines on Oak Road along the project frontage would be underground similar to the property to the north. We noticed there is no street trees along the property to the north. Will the County be looking for similar “open” appearance along the project frontage on Oak and Jones Roads? We assume the existing street trees on Oak Road are to remain. 7. Any known offsite drainage issues surrounding the project site. We will reach out to the County Public Works staff as well. 8. We understand this property is served by Central Sanitary District and CCCWD. Any known capacity issues we should be aware of. Likewise, we will and have reached out to the District. 9. We are not anticipating many retaining walls with the proposed development. But any maximum wall heights restriction and how are the heights of wall measured (from top of footing?). Architectural Questions 1.Net site area is to be calculated as .8 x gross site area, please confirm. 2.Density is calculated as number of units / net site area, please confirm. 3.We are assuming that Oak Rd. is the project frontage and would be considered the front setback distance, please confirm. 4.These are the setback distances we have used in our site planning, please confirm: 1.Front = 20’ 2.Sides = 15’ 3.Rear = 20’ 4.Between Buildings = 20’ 5.Architectural projections such as covered porches and decks are allowed to encroach into setbacks at least 5’ – please confirm. 5.Open space requirements are 25% of the site area? Please confirm and provide any minimum dimensional requirements. 6.Building coverage is proposed to be 40% maximum, please confirm. 7.We are using a guest parking ratio of .25/unit, please confirm. 8.We understand that required parking can be satisfied with on-street parking along the project frontage, please confirm. 9.It is our understanding that EV stalls are not required for surface parking. Please confirm. 10.It is our understanding that 26’ main drive aisles and 20’ alleys per fire code are permitted. Please confirm. 11.Residential trash service is planned to be individual trash/recycling carts, picked up from the driveway aprons, and stored in designated locations within the individual unit garages. Please confirm. 12.The project will comply with current California Building Codes, and Energy Codes. Are there any other specific Green Energy Codes that would apply to the project? 777 S.

This Project Description accompanies the Preliminary Review Procedure Application to provide additional information to City staff of the project qualities and characteristics. Location and Setting The site is located at 2740 Jones Road and contains several existing buildings, homes, structures and was the site of the Palmer School until the advent of Covid 19 which resulted in a permanent closure. The site is generally flat and extends between Jones and Oak Roads. The property is surrounded by offices, hotel/spa and two- and three-story rental apartments, townhouses and about a dozen small lot single family detached homes. Interstate 680 and the BART tracks are to the immediate west and the Pleasant Hill BART station is a short walk to the north. Project Overview • SummerHill Homes proposes to develop 114 three story for sale townhomes on the site consistent with the General Plan density of 22-29.9 du/ac. The proposed density is less than 25 du/acre. The massing and articulation of the four to nine-unit townhome buildings will be consistent with established neighborhood immediately to the north of the site. • Three-unit types are proposed and range in size from 1,600 sf to 2,100 sf with attached two car garages, 3 to 4 bedrooms and 2.5 to 3.5 bathrooms. • Building height ranges from 37' to 40' to the ridge line. • Setbacks vary from 15' to 20' and will be remain flexible until the final site plan is designed. • The preliminary programming of the project includes common landscaped open space and retention of the large oak near the Oak St frontage. • A significant centrally located common open space area and other similar smaller gathering areas are included. Approximately 25% of the site is open space. Project arborist identified significant trees including the largest one on the site to be retained as shown on the Preliminary Conceptual Site Plan and tree map which are included in the Pre-Application materials. A tree report including all the trees will accompany the formal application. 777 S. California Ave, Palo Alto, CA 94304 phone 650.493.4040 fax 650.857.1077 shhousinggroup.com •Parking is provided and includes approximately 264 spaces with an attached 2 car garage for each home. Approximately 34 surface parking spaces are provided not including adjacent offsite parking along Jones and Oak Roads which we understand can also be counted for required parking. 257 spaces are required. •Primary vehicular access is provided from the main driveways on Jones and Oak Roads which also serve as emergency vehicle access. •The project will benefit the County's affordable housing program by contributing an in-lieu fee in accordance with the County requirements. Requested Approvals The project will require PD zoning, Land Use Permit with Final Development Plan, Vesting Tentative Map, Tree Removal Permit, Demolition Permit, Grading Permit and CEQA approval. Design and Construction The residential units will be built to an R-2 Occupancy Classification and be fully sprinklered. Sustainability SummerHill Homes will construct the project in compliance with California Green Building Standards Code (Title 24) in effect at the time. The projects grading, drainage and storm water runoff plans will minimize changes to the grade, contain as much water on site, and appropriately filter runoff.

Project Description The project site is approximately 5.9 +/- acres and is located at the southwest corner of and between Oak Road and Jones Road in Contra Costa County within the City of Walnut Creek Sphere of Influence. The proposed project is a residential development and consists of approximately 125 condominium units in 19 3-story buildings with common area walkways, open space, on-site private streets and roadways and parking. Access to the project site will be from Jones Road and Oak Road, which is within the City of Walnut Creek right of way. The City/County boundary coincides with the project site easterly property line at approximately the back of existing sidewalk along Oak Road. II. Existing Condition The project site is the former Palmer School site, which consists of several existing classrooms, dormitory, library, administration and maintenance, athletics buildings, an outdoor swimming pool, paved sports fields, concrete walkways, AC paved roadways, and open area ballfields. The project site is generally flat with a gentle slope of approximately 5% in the northeasterly direction towards Oak Road, northwesterly towards Jones Road and with a localized portion of the site at the southwesterly portion of the site drains towards Jones Road as well. Currently, the on-site drainage and storm runoff generally sheet flows across the site or captured by on-site small drainage inlets connected by underground storm drain pipes and discharged into the existing storm drain facilities in Jones Road or Oak Road. Based on field observation and record drawings, it appears majority of the existing on-site drainage is discharged or conveyed via underground storm drains to the existing 30” storm drains in Oak Road. An existing Drainage Area Map, Exhibit A, showing the existing drainage pattern and boundary is included for reference. The project site is within the Contra Costa County Flood Control Drainage Area 44B as shown on the “Drainage Area 44B Working As-built Drawing” attached in Appendix A for reference. According to the attached Drainage Area 44B drawing, the project is tributary to the existing 30” storm drain, “Line D – 1,” in Oak Road and the existing 72” storm drain, “Line C,” in Jones Road. These existing storm drains eventually converge at the intersection of Jones Road and Oak Road and discharge into an existing 84” storm drain, “Line A,” which continues flowing east along Jones Road and turns north along the Railroad right of way and continues flows in a northerly direction. Attached is the “Existing Condition Plan,” Exhibit B, showing the existing drainage system in Oak Road and Jones Road for reference. G:\job2020\201069\Hydro\Hydro \Hydrology and Hydraulics.doc Page 2 III. Design Criteria The hydrology calculations to generate the post development flow rate are based on the rational method in accordance with Contra Costa County Flood Control District (CCCFCD) hydrology standards as follows:  Rational method (Q = CIA), whereas • Q = Flow Rate (cfs) • C = Runoff Coefficient • I = Intensity (in//hr) • A = Area (acres) The parameters and criteria used for the calculations and analysis are in accordance with the requirements as shown on the Contra Costa County Flood Control District Documents and Standards, Hydrology Standards, and the following standards are applied:  Mean Annual Precipitation is based on the Mean Seasonal Isohyet Map with GIS Feature Overlay, dated December 1977, attached in Appendix B for reference.  Runoff Coefficient, C value, is based on the CCCFCD Standard Runoff Coefficient Table attached in Appendix B.  Rainfall Intensity, I value, is based on CCCFCD Intensity-Duration- Frequency Curves attached in Appendix B for reference.  A freeboard requirement of 1.25’ from finished top of curb elevations is assumed for this calculation. IV. Calculations and Analysis Based on the Design Criteria from the Contra Costa County Flood Control District per Item III above, hydrology and hydraulic calculations were performed using the Hydraflow Storm Sewer Software Program by Autodesk Civil 3D to evaluate the hydraulic characteristics and performance of the proposed on-site storm drains. The following parameters are used for this calculation:  Mean Annual Precipitation = 19 inches  Runoff Coefficient, C value = 0.75  Rainfall Intensity, I value (10-year) = 3.03 in./hr. (peak)  Rainfall Intensity, I value (100-year) = 4.69 in./hr. (peak), G:\job2020\201069\Hydro\Hydro \Hydrology and Hydraulics.doc Page 3  Starting Hydraulic Grade Line (HGL) (See Note 1 below)  Initial time of concentration, Tc = 5 minutes Note 1: The starting HGL is based on the elevation obtained from the record drawings Contra County Flood Control Drainage Area 44B and Tract 6470 Oak Road Villas 1 attached in Appendix A for reference. Analysis was performed to evaluate the pre and post development impervious surface and potential impact and mitigation needed to mitigate increase in the post development impervious surface areas and the need for on-site storage to meet the no net increase and/or hydromodification requirements. It appears, based on our calculations, that there is a net increase of the post development impervious surface area:  Post Development Impervious Area = 155,600 SF  Pre Development Impervious Area = 195,736 SF Net Increase = 36,420 SF Due to the net increase of the post development impervious surface area, hydrograph calculation was performed, using the Hydraflow Software Program by Autodesk Civil 3D to evaluate and determine the storage volumes needed to mitigate peak flow rates for 10 and 100-year storm events such that adequate on- site storage facility is provided. In addition, the project site is subject to hydromodification in accordance with the Contra Costa County C.3 Technical Guidance requirement to evaluate and determine the storage capacity requirement to meet the hydromodification. The Contra Costa County hydrology model was used to calculate the storage capacity to mitigate the potential increased flow between the 2 to 10-year storms. It is noted that the 6” ponding for the proposed bio-retention is taken into consideration with this calculation to optimize the calculations. V. Results The results of the hydraflow and hydromodification calculations are included in the “Storm Sewer Tabulation” table in Appendix C, the hydrograph calculations in Appendix D, and the hydrology model report in Appendix E for reference. Based on the above calculations the on-site storm drain system has been designed to meet the County’s hydraulic requirements and the 1.25’ freeboard. Based on the hydrograph and hydromodification calculations, it appears on-site storage facilities of 2,800 cubic feet would be needed to mitigate the potential increase of post development flows and to meet the hydromodification requirements. To meet this requirement, two underground storage vaults are proposed to capture, store, G:\job2020\201069\Hydro\Hydro \Hydrology and Hydraulics.doc Page 4 and release the post development storm flow into the existing off-site storm drainage facilities. These two vaults are placed at the downstream ends of the on- site storm drains at the respective discharge points at Oak Road and Jones Road as shown on the Drainage Area Map, Exhibit C.

SETTING II.A. Project Location and Description The project site is approximately 5.9 +/- acres and is located at the southwest corner of and between Oak Road and Jones Road in Contra Costa County within the City of Walnut Creek Sphere of Influence. The proposed project is a residential development and consists of approximately 125 condominium units in 19 3-story buildings with common area walkways, open space, on-site private streets and roadways and parking. Access to the project site will be from Jones Road and Oak Road, which is within the City of Walnut Creek right of way. The City/County boundary coincides with the project site easterly property line at approximately the back of existing sidewalk along Oak Road. A Vicinity Map, Exhibit A, showing the project site location is included for reference. II.B. Existing Site Features and Conditions The project site is the former Palmer School site, which consists of several existing classrooms, dormitory, library, administration and maintenance, athletics buildings, an outdoor swimming pool, paved sports fields, concrete walkways, AC paved roadways, and open area ballfields. The project site is generally flat with a gentle slope of approximately 5% in the northeasterly direction towards Oak Road, northwesterly towards Jones Road and with a localized portion of the site at the southwesterly portion of the site drains towards Jones Road as well. Currently, the on-site drainage and storm runoff generally sheet flows across the site or captured by on-site small drainage inlets connected by underground storm drain pipes and discharged into the existing storm drain facilities in Jones Road or Oak Road. Based on field observation and record drawings, it appears majority of the existing on-site drainage is discharged or conveyed via underground storm drains to the existing 30” storm drains in Oak Road. An existing Drainage Area Map, Exhibit C, showing the existing drainage pattern and boundary is included for reference. The project site is within the Contra Costa County Flood Control Drainage Area 44B. According to the attached Drainage Area 44B drawing, the project is tributary to the existing 30” storm drain, “Line D – 1,” in Oak Road and the existing 72” storm drain, “Line C,” in Jones Road. These existing storm drains eventually converge at the intersection of Jones Road and Oak Road and discharge into an existing 84” storm drain, “Line A,” which continues flowing east along Jones Road and turns north along the Railroad right of way and continues flows in a northerly direction. Attached is the Existing Condition Plan, Exhibit B, showing the existing drainage system in Oak Road and Jones Road for reference. Oak Road Townhouse Condominiums Page 3 of 11 March 22, 2021 II.C. Opportunities and Constraints for Stormwater Control 1. The low permeability and high clay content of the site soil combined with previously high ground water table make it undesirable to promote infiltration. 2. The proposed project is a small in-fill site with physical constraints and existing improvements and developments surrounding the project site limiting use of sediment basins. 3. Due to nature of this development, parkway strips and/or open landscape areas are limited where these areas could be utilized for LID treatment areas. However, pockets of landscape areas between the proposed buildings and roadways, and open space in the central portion of the project site could be utilized for LID treatment. The new impervious surfaces will be conveyed through drainage swales and/or bubble ups and treated prior to discharging into the underground storm drains. III. LOW IMPACT DEVELOPMENT DESIGN STRATEGIES III.A. Optimization of Site Layout Due to the nature of the development on the density (required by the County Planning Department) and space needed for utilities, underground utility boxes, transformers, and backflow devices, etc., limited open space or landscape area is available for treatment purposes. Given the physical constraints and limitations, treatment is optimized by breaking up the new and/or replaced impervious areas in small drainage management areas (DMA’s) and by using drainage swales, curb openings, bubble ups to convey the runoff to the treatment areas in paseos, landscape pockets between walkways/buildings and the center open space area on the project site. By implementing this approach, low impact development (LID) bio- retention treatment is dispersed throughout the site, which enables the project to treat 100% of the impervious surface with the bio-retention measures. Each DMA is documented in the following Section IV for reference. III.B. Bioretention or other Integrated Management Practices As discussed in Section III.A. above, the proposed project will utilize and integrate the bio-retention technique and approach to meet the LID treatments in compliance with the requirements set forth in the County C.3 Technical Guidance. Bio-retention functions as soil and plant based filtration that removes pollutants through a variety of physical, biological, and chemical process. These facilities consist of a layer of cobble stone (mulch is not recommend), planted landscape (grass, shrub or trees), sandy loam soil Oak Road Townhouse Condominiums Page 4 of 11 March 22, 2021 (with a minimum percolation rate of 5 inches/hour and a maximum percolation rate of 10 inches/hour), drain rock and under drains. The stormwater runoff from impervious surface is directed and passed through the bio-retention areas and distributed evenly along a ponding area. Stormwater runoff will percolate through the sandy loam treatment soil and eventually captured by the under drains and discharged into the underground storm drains. A Preliminary Stormwater Treatment Plan, Exhibit D, showing locations and details of the bio-retention is included for reference. IV. DOCUMENTATION OF DRAINAGE DESIGN IV.A.

Sizing of Bio-Retention Impervious surface and pervious surface areas from each DMA outlined above are input into the County IMP sizing calculator to calculate and determine the require bio-retention area to treat each DMA. The output and results of the IMP calculations are included in Appendix A for reference. Oak Road Townhouse Condominiums Page 10 of 11 March 22, 2021 V. SOURCE CONTROL MEASURES V.A. Site Activities and Potential Sources of Pollutants Source controls prevent potential pollutant sources from contacting rainfall and stormwater. Source control measures consist of structural or operational “good housekeeping” practices. The following source control measures will be implemented: • Use non-chemical controls before using chemicals to treat a pest problem and pest resistant. • Select planting materials to site specific characteristics such as soil type, climate, prevailing wind, sunlight, or rainfall to ensure successful establishment. • Regular sweeping of streets and sidewalk to minimize accumulation of litter or debris. • Routine inspection and cleaning of stormwater inlets and trash capture devices. • Storm drain inlets clearly marked “no dumping – drains to bay”. • Proper maintenance of landscaping with minimal pesticide and fertilizer use. • Project CC&R’s or education materials to inform tenants and/or building owners that no person shall dispose of, or permit the disposal, directly or indirectly of vehicle fluids, hazardous materials or rinsed water from tools, equipment, or trash cans into storm drains. • Regularly mow grass in bio-retention areas and remove clippings from the site. • Install trash capture devices in stormwater inlets. VI. STORMWATER FACILITY MAINTENANCE VI.A. Ownership and Responsibility for Maintenance in Perpetuity Maintenance is essential for assuring the stormwater treatment measures function effectively and do not cause flooding, provide habitat for mosquitos or otherwise become a nuisance. Essential maintenance will include: • Flushing the storm drain pipes as needed before the rainy season begins. • Inspect and service the trash capture devices • Inspect and service the bio-retention treatment areas. • Perform other site source controls. Oak Road Townhouse Condominiums Page 11 of 11 March 22, 2021 The homeowners association (HOA) of the proposed residential development will be responsible for providing adequate funding to maintain these post-construction stormwater treatment measures. An Operation and Maintenance (O&M) Agreement will be executed by the HOA with the City at project approval stage accepting responsibility for maintenance as well as ensuring access to the City, Water Board, Alameda County Mosquito Abatement District or Vector Control District for routine inspection. VI.B. Summary of Maintenance Requirements for Each Stormwater Facility Maintenance plans outlining routine activities and frequency of the maintenance for bio-retention and trash capture devices are included in the Appendix B for reference. VII. CONSTRUCTION PLAN C.3 CHECKLIST The construction plans and the corresponding checklist will be prepared after the entitlement and planning approval for the County’s review and approval prior to issuance of construction permits. VIII. CERTIFICATION Certification stating “The selection, sizing, and preliminary design of stormwater treatment and other control measures in this plan meet the requirements of Regional Water Quality Control Board Order R2-2015-0049” will be provided as required prior to final approval of the stormwater control plan and starting of construction.

APPENDIX B MAINTENANCE PLANS Bio-Retention Maintenance Plan I. Routine Maintenance Activities The maintenance objective is to prevent sediment buildup and clogging and to keep up the pollutant removal efficiency by maintaining a dense, healthy vegetated cover. Routine maintenance activities, and the frequency at which they will be conducted, are shown in the table below. Table 1 Routine Maintenance Activities for Bioretention Areas No. Maintenance Task Frequency of Task 1 Remove obstructions, debris and trash from bioretention area and dispose of properly. Monthly, or as needed after storm events 2 Inspect bioretention area to ensure that it drains between storms and within five days after rainfall. Monthly, or as needed after storm events 3 Inspect inlets for channels, soil exposure or other evidence of erosion. Clear obstructions and remove sediment. Monthly, or as needed after storm events 4 Remove and replace all dead and diseased vegetation. Twice a year 5 Maintain vegetation and the irrigation system. Prune and weed to keep bioretention area neat and orderly in appearance. Before wet season begins, and after wet season 6 Till or replace soil (using soil mix specified in C.3 Technical Guidance Appendix K) as necessary to maintain the design elevation of soil (see Section V, Soil Mixing and Replacement for proper installation of bio- retention soils). As needed when bio-retention area does not drain between storms and within 5 days after rainfall 7 Check if cobble stone is missing, patching or out of place and replace as necessary before wet season begins. Monthly, or before wet season begins. 8 Inspect bioretention area using the attached inspection checklist. Monthly, or after large storm events, after wet season, and monthly during wet season II. Prohibitions The use of pesticides and quick release fertilizers shall be minimized, and the principles of integrated pest management (IPM) followed: 1. Employ non-chemical controls (biological, physical and cultural controls) before using chemicals to treat a pest problem. 2. Prune plants properly and at the appropriate time of year. 3. Provide adequate irrigation for landscape plants. Do not over water. 4. Limit fertilizer use unless soil testing indicates a deficiency. Slow-release or organic fertilizer is preferable. Check with municipality for specific requirements. 5. Pest control should avoid harming non-target organisms, or negatively affecting air and water quality and public health. Apply chemical controls only when monitoring indicates that preventative and non-chemical methods are not keeping pests below acceptable levels. When pesticides are required, apply the least toxic and the least persistent pesticide that will provide adequate pest control. Do not apply pesticides on a prescheduled basis. 6. Sweep up spilled fertilizer and pesticides. Do not wash away or bury such spills. 7. Do not over apply pesticide. Spray only where the infestation exists. Follow the manufacturer’s instructions for mixing and applying materials. 8. Only licensed, trained pesticide applicators shall apply pesticides. 9. Apply pesticides at the appropriate time to maximize their effectiveness and minimize the likelihood of discharging pesticides into runoff. With the exception of pre-emergent pesticides, avoid application if rain is expected. 10. Unwanted/unused pesticides shall be disposed as hazardous waste. Standing water shall not remain in the treatment measures for more than five days, to prevent mosquito generation. Should any mosquito issues arise, contact the Alameda County Mosquito Abatement District (ACMAD), as needed for assistance. In Albany, contact the Alameda County Vector Control Services District (ACVCSD). Mosquito larvicides shall be applied only when absolutely necessary, as indicated by the ACMAD or ACVCSD, and then only by a licensed professional or contractor. Contact information for ACMAD and ACVCSD is provided below. III. Vector Control Contacts Alameda County Mosquito Abatement District 23187 Connecticut St. Hayward, CA 94545 Phone: (510) 783-7747 Alameda County Vector Control Services District 1131 Harbor Bay Parkway, Ste. 166 Alameda, CA 94502 Phone: (510) 567-6800 IV. Inspections The attached Bioretention Area Inspection and Maintenance Checklist shall be used to conduct inspections monthly (or as needed), identify needed maintenance, and record maintenance that is conducted. V. Soil Mixing and Placement  Do not excavate, place soils, or amend soils during wet or saturated conditions.  Operate equipment adjacent to (not in) the facility.  If machinery must operate in the facility, use light weight, low ground-contact pressure equipment.  It may be necessary to rip or scarify the bottom soils to promote greater infiltration or excavate any sediment that may have built up during construction.  Consider the time of year and site working area when determining whether to mix bioretention soil on-site or to import pre-mixed soil.  If mixing bioretention media on-site, use an adjacent impervious area or on plastic sheeting.  Place soil in 12”lifts with machinery adjacent to the facility. If working within the facility, to avoid over-compacting, place first lifts at far end from entrance and place backwards towards entrance.  Do not place or work bioretention soil if it is saturated or raining.  Allow bioretention soil lifts to settle naturally, boot pack (walk around to firm) lifts to achieve 85% compaction effort. After all lifts are placed, wait a few days to check for settlement, and add additional media as needed.  An alternative to boot compaction is to settle bioretention soils by lightly watering until soils are just saturated. Allow soil to dry between lifts. It may take a day or more to dry adequately between lifts. Soil cannot be worked when saturated so this method should be used with caution. Allow for extra time to let soils dry between each lift. After all lifts are placed, wait a few days to check for settlement, and add additional media as needed.  Verify bioretention soil elevations before applying cobble stone or installing plants.

Routine Maintenance Activities The maintenance objective is to minimize trash going into the storm drain system by capturing and removing trash at the storm water inlets at location where storm water entering into the storm drain system. Routine maintenance activities at which they will be conducted are outlined below. 1. The storm water inlet should be inspected and serviced at a minimum two times per year. One inspection and service should be conducted before the rainy season begins annually and one should be conducted after the rainy season is ended. 2. Clean surface area immediately around each storm water inlet utilizing a stiff bristled push-broom, flat shovel or industrial vacuum. 3. Remove grate cover and set aside. 4. Inspect trash capture filter and ensure it is secured in the storm water inlet. Replace device, if damaged, as needed. 5. Remove debris trapped in grate slot openings. 6. Utilize an industrial vacuum to remove debris from within storm water inlet. 7. Place grate cover back on storm water inlet grate frame. 8. Secure dated service lock-out tag on grate lid. 9. Identify storm water inlet on site map for tracking and reporting. 10. Note observations, concerns or recommendation on maintenance report.

The project consists of approximately 125 townhouse-style for sale condominium units. The three-story units are planned to occupy the site which was previously occupied by a school and is east of I-680, BART tracks, and Jones Road and west of Oak Road. Following is a summary of our findings: ● Estimated environmental noise levels, due to transportation sources, fall into the County’s normally acceptable to normally unacceptable land use compatibility categories for multi-family residences. Noise reduction measures, in the form of sound-rated windows and exterior doors, will be needed to meet the County and State noise goals. ● Preliminary estimates show that windows and exterior doors with sound insulation ratings of up to STC 39 will be needed to meet the County and State criteria for interior noise due to exterior sources. ● Outdoor use space will be provided in the form of second-story balconies at some unit plans, and roof decks at units along Oak Road. A common open space is provided mid-site to meet the County’s guidelines. ACOUSTIC CRITERIA Contra Costa County General Plan Policy 11-1 of the Noise Element of the 2005-2020 Contra Costa General Plan provides Noise and Land Use Compatibility Guidelines for new multi-family residential projects, which are summarized in Table 1. Oak Road Townhouse Condos – Contra Costa County, CA 29 January 2021 Environmental Noise Assessment Page 3 Table 1: Summary of Noise Land Use Compatibility Guidelines for Multi-family Residential Projects Exterior DNL Land Use Category 60 dB 1 or less Normally Acceptable: Specified land use is satisfactory, based upon the assumption that any buildings involved are of normal conventional construction, without any special noise insulation requirements. 55 to 70 dB Conditionally Acceptable: New construction or development should be undertaken only after a detailed analysis of the noise reduction requirements and needed noise insulation features included in the design. 70 to 75 dB Normally Unacceptable: New construction or development should generally be discouraged. If new construction or development does proceed, a detailed analysis of the noise reduction requirements must be made and needed noise insulation features included in the design. 75 dB(A) or higher Unacceptable: New construction or development clearly should not be undertaken. The County’s General Plan also includes the following policies: ● Policy 11-2 provides a goal for outdoor noise levels in residential areas of DNL 2 60 dB. The policy notes this might not be achievable in all residential areas due to economic or aesthetic constraints (e.g., at small balconies associated with multi-family housing). Where this is the case, the policy proposes an alternate of providing a common outdoor use area that meets the goal. ● Policy 11-3 provides an alternative outdoor noise goal of DNL 70 dB in areas where the primary noise source is BART passbys. ● Policy 11-4 reinforces the State requirement of interior noise level of DNL 45 dB or less, due to exterior sources. ● Policy 11-5 provides a goal to reduce instantaneous noise from BART events to 50 dB in bedrooms and 55 dB in other habitable rooms. California Building Code Title 24, Part 2 of the California Code of Regulations requires that new multi-family residential projects achieve an interior noise level of DNL 45 dB or less, due to exterior environmental sources. 1 dB (Decibel) – A unit that describes the magnitude of a sound with respect to a reference sound level near the threshold of hearing. Decibels are based on a logarithmic scale and therefore cannot be added arithmetically. 2 DNL (Day-Night Average Sound Level) – A descriptor for a 24-hour A-weighted average noise level. DNL accounts for the increased acoustical sensitivity of people to noise during the nighttime hours. DNL penalizes sound levels by 10 dB during the hours from 10 PM to 7 AM. DNL is sometimes written as Ldn. Oak Road Townhouse Condos – Contra Costa County, CA 29 January 2021 Environmental Noise Assessment Page 4 NOISE ENVIRONMENT The noise environment at the project site is influenced by vehicle traffic on Oak Road, Jones Road, and Interstate I-680, as well as from BART trains on the adjacent tracks. To help quantify environmental noise levels, a monitor continuously measured noise levels at the site between 7 and 11 December 2020. In addition, two short-term “spot” measurements were conducted to help determine how noise levels vary with location and elevation. For reference, a COVID-19 health order took effect on 5 December 2020, which was understood to reduce the volume of traffic on the roadways.3 Figure 1, attached, summarizes the noise measurement locations, and Table 2, below, summarizes the measured noise levels. Table 2: Measured Noise Levels Site Location Date/Time DNL L1 Oak Road Monitor Approximately 40’ west of Oak Road centerline, 12’ above grade 7 to 11 December 2020 DNL 68 dB L2 Mid-Site Monitor Approximately 210’ west of Oak Road centerline, 12’ above grade 7 to 11 December 2020 DNL 60 dB L3 Jones Road/BART/I-680 Monitor Approximately 35’ east of Jones Road centerline, 12’ above grade 7 to 11 December 2020 DNL 65 dB S1 Oak Road Spot Approximately 50’ west of Oak Road, 5’ above grade 7 December 2020 3:50-4:05 PM DNL 66 dB S2 Jones Road Spot Approximately 35’ east of Jones Road centerline, 5’/16’ above grade 11 December 2020 8:15-8:35 AM DNL 66/67 dB In addition to the average levels identified above, measured typical maximum instantaneous noise levels due to BART passbys were approximately Lmax30 80 dB 4 at monitor location L3 (i.e., the monitoring location closest to the BART). In our analysis and recommendations section below, we have added 1 dB to account for future traffic volume increases.5 3 Consider conducting additional measurements when traffic patterns return to normal, prior to construction, to confirm estimated levels. 4 Lmax30 (Typical Maximum Sound Level) – There is no standardized metric to quantify “typical” maximum sound levels in an environment (instead of the absolute maximum sound level for a measurement period). The metric Lmax30 comes from a paper by Rob Greene (“Max Level Intrusive Noise Limit: 1982 National Conference on Environmental and Occupational Noise”). It is based on the logarithmic average of the noisiest 30 percent of single events (e.g., train passbys, aircraft flyovers). 5 The California Department of Transportation assumes a traffic volume increase of three percent per year, which corresponds to a 1 dB increase in DNL over a ten-year period. This should be reviewed when the traffic study for the project is available, as long-term impacts to traffic patterns associated with COVID-19 are not yet known and could affect future environmental noise levels. Oak Road Townhouse Condos – Contra Costa County, CA 29 January 2021 Environmental Noise Assessment Page 5 ANALYSIS AND RECOMMENDATIONS Estimated future noise levels at future facades range from DNL 60 dB at interior shielded portions of the site to approximately DNL 74 dB at elevated locations nearest the BART tracks and I-680.6 This falls into the County’s normally acceptable to normally unacceptable land use compatibility categories for multi- family residences. Therefore, exterior building assemblies will need to be sound rated to reduce transportation noise to the criteria outlined above. Exterior-to-Interior Noise As indicated above, the interior noise criteria are DNL 45 dB in residences due to all outdoor environmental sources, and Lmax 50 and 55 dB, due to BART, in bedrooms and other habitable rooms, respectively. Preliminary estimates show window and exterior door ratings up to STC7 39 will be needed, as shown in Figure 2, attached. These preliminary estimates are based on the following, and will need to be updated based on finalized floor plans, elevations, and window sizes prior to construction. ● Conceptual floor plans and elevations per the P-1 Rezoning Preliminary Final Development Plan dated 23 December 2020 ● Exterior walls will be equivalent to stucco over wood sheeting with batt insulation in stud cavities and at least 1 layer of gypsum board on the interior ● Flooring in bedrooms will be carpet over pad Window and door sound insulation ratings must be for the complete tested assembly, including glass and frame, and should be based on laboratory test reports of similar sized samples from an NVLAP accredited lab. For reference, typical construction grade dual-pane windows achieve sound insulation ratings of approximately STC 28. Where no rating is indicated in Figure 2, these ratings are assumed. Ventilation systems must not compromise sound insulation of the exterior wall assemblies. Where windows will need to be closed to meet the interior noise criterion, an alternate means of providing outside air to habitable spaces should be provided. The ventilation systems will need to maintain the exterior-to-interior noise reduction of the overall facade. Details should be developed during the design phase. 6 Estimates are based on noise levels measured at the site along with published levels identified in the Contra Costa County General Plan, Walnut Creek General Plan, Walnut Creek BART Transit Village Draft EIR, and Caltrans traffic counts. 7 STC (Sound Transmission Class) – A single-number rating defined in ASTM E90 that quantifies the airborne sound insulating performance of a partition under laboratory conditions. Increasing STC ratings correspond to improved airborne sound insulation. Oak Road Townhouse Condos – Contra Costa County, CA 29 January 2021 Environmental Noise Assessment Page 6 Outdoor noise Conceptual unit plans include 2nd floor decks for some units, and roof decks at units along Oak Road. Following is a discussion comparing levels with the County’s General Plan policies: ● Along Oak Road levels will exceed the County’s DNL 60 dB goal. Therefore, common open space is provided towards the center of the site where transportation noise is consistent with the goal. ● Along Jones Road the measured level at the second story elevation was DNL 67 dB, which is consistent with the County’s goal for outdoor locations exposed to BART noise. Therefore, noise reduction measures are not required. * * * Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR FirstCarbon Solutions H.2 - Draft Environmental Noise Assessment (May 2021) THIS PAGE INTENTIONALLY LEFT BLANK Oak Road Townhouse Condos Contra Costa County, California DRAFT ENVIRONMENTAL NOISE ASSESSMENT 7 May 2021 Prepared for: SummerHill Homes Marshall Torre 3000 Executive Parkway, Suite 450 San Ramon, CA 94583 mtoore@shhomes.com Prepared by: Salter Josh Roper, PE, LEED AP Justin Reidling jroper@salter-inc.com jreidling@salter-inc.com Salter Project 20-0343 Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 2 INTRODUCTION This report summarizes our environmental noise assessment for the Oak Road Townhouse Condos project located at 2740 Jones Road in unincorporated Walnut Creek, under the jurisdiction of Contra Costa County, California. The project consists of approximately 125 townhouse-style for sale condominium units. The three-story units are planned to occupy the site which was previously occupied by a school and is east of I-680, BART tracks, and Jones Road and west of Oak Road. Following is a summary of our findings: ● Estimated environmental noise levels, due to transportation sources, fall into the County’s normally acceptable to normally unacceptable land use compatibility categories for multi-family residences. Noise reduction measures, in the form of sound-rated windows and exterior doors, will be needed to meet the County and State noise goals. ● Preliminary estimates show that windows and exterior doors with sound insulation ratings of up to STC 39 will be needed to meet the County and State criteria for interior noise due to exterior sources. ● Outdoor use space will be provided in the form of second-story balconies at some unit plans, and roof decks at units along Oak Road. A common open space is provided mid-site to meet the County’s guidelines. ● Project-generated traffic will not significantly increase environmental noise in the project vicinity. ● Noise from outdoor condensing units should be evaluated during the design phase. Based on the existing noise environment, including noise from I-680 and BART, operational noise from mechanical equipment shall be limited to DNL 60 dB at adjacent receivers. ● Consistent with the General Plan, construction hours shall be limited to reduce the impact on adjacent off-site receivers. For readers less familiar with the fundamental concepts of environmental noise, please refer to Appendix A attached. ACOUSTIC CRITERIA Contra Costa County General Plan (GP) Policy 11-1 of the Noise Element of the 2005-2020 Contra Costa General Plan provides Noise and Land Use Compatibility Guidelines for new multi-family residential projects, which are summarized in Table 1. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 3 Table 1: Summary of Noise Land Use Compatibility Guidelines for Multi-family Residential Projects Exterior DNL Land Use Category 60 dB1 or less Normally Acceptable: Specified land use is satisfactory, based upon the assumption that any buildings involved are of normal conventional construction, without any special noise insulation requirements. 55 to 70 dB Conditionally Acceptable: New construction or development should be undertaken only after a detailed analysis of the noise reduction requirements and needed noise insulation features included in the design. 70 to 75 dB Normally Unacceptable: New construction or development should generally be discouraged. If new construction or development does proceed, a detailed analysis of the noise reduction requirements must be made and needed noise insulation features included in the design. 75 dB(A) or higher Unacceptable: New construction or development clearly should not be undertaken. The County’s General Plan also includes the following policies: ● Policy 11-2 provides a goal for outdoor noise levels in residential areas of DNL2 60 dB. The policy notes this might not be achievable in all residential areas due to economic or aesthetic constraints (e.g., at small balconies associated with multi-family housing). Where this is the case, the policy proposes an alternate of providing a common outdoor use area that meets the goal. ● Policy 11-3 provides an alternative outdoor noise goal of DNL 70 dB in areas where the primary noise source is BART passbys. ● Policy 11-4 reinforces the State requirement of interior noise level of DNL 45 dB or less, due to exterior sources. ● Policy 11-5 provides a goal to reduce instantaneous noise from BART events to 50 dB in bedrooms and 55 dB in other habitable rooms. ● Policy 11-8 states “Construction activities shall be concentrated during the hours of the day that are not noise-sensitive for adjacent land uses and should be commissioned to occur during normal work hours of the day to provide relative quiet during the more sensitive evening and early morning periods.” California Building Code (CBC) Title 24, Part 2 of the California Code of Regulations requires that new multi-family residential projects achieve an interior noise level of DNL 45 dB or less, due to exterior environmental sources. 1 dB (Decibel) – A unit that describes the magnitude of a sound with respect to a reference sound level near the threshold of hearing. Decibels are based on a logarithmic scale and therefore cannot be added arithmetically. All sound levels in this report are A-weighted. 2 DNL (Day-Night Average Sound Level) – A descriptor for a 24-hour A-weighted average noise level. DNL accounts for the increased acoustical sensitivity of people to noise during the nighttime hours. DNL penalizes sound levels by 10 dB during the hours from 10 PM to 7 AM. DNL is sometimes written as Ldn. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 4 California Environmental Quality Act (CEQA) The 2018 Amendments to the CEQA Guidelines contain a checklist intended to determine whether the project would create a noise impact on the surrounding community. The checklist items ask whether the project would: ● Generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local General Plan or Noise Ordinance, or applicable standards of other agencies? ● Generate excessive ground-borne vibration or ground-borne noise levels? ● For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? NOISE ENVIRONMENT The noise environment at the project site is influenced by vehicle traffic on Oak Road, Jones Road, and Interstate I-680, as well as from BART trains on the adjacent tracks. To help quantify environmental noise levels, a monitor continuously measured noise levels at the site between 7 and 11 December 2020. In addition, two short-term “spot” measurements were conducted to help determine how noise levels vary with location and elevation. For reference, a COVID-19 health order took effect on 5 December 2020, which was understood to reduce the volume of traffic on the roadways.3 Figure 1, attached, summarizes the noise measurement locations, and Table 2, below, summarizes the measured noise levels. Table 2: Measured Noise Levels Site Location Date/Time DNL L1 Oak Road Monitor Approximately 40’ west of Oak Road centerline, 12’ above grade 7 to 11 December 2020 DNL 68 dB L2 Mid-Site Monitor Approximately 210’ west of Oak Road centerline, 12’ above grade 7 to 11 December 2020 DNL 60 dB L3 Jones Road/BART/I-680 Monitor Approximately 35’ east of Jones Road centerline, 12’ above grade 7 to 11 December 2020 DNL 65 dB S1 Oak Road Spot Approximately 50’ west of Oak Road, 5’ above grade 7 December 2020 3:50-4:05 PM DNL 66 dB S2 Jones Road Spot Approximately 35’ east of Jones Road centerline, 5’/16’ above grade 11 December 2020 8:15-8:35 AM DNL 66/67 dB 3 Consider conducting additional measurements when traffic patterns return to normal, prior to construction, to confirm estimated levels. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 5 In addition to the average levels identified above, measured typical maximum instantaneous noise levels due to BART passbys were approximately Lmax30 80 dB4 at monitor location L3 (i.e., the monitoring location closest to the BART). In our analysis and recommendations section below, we have added 1 dB to account for future traffic volume increases.5 ANALYSIS AND RECOMMENDATIONS Estimated future noise levels at future facades range from DNL 60 dB at interior shielded portions of the site to approximately DNL 74 dB at elevated locations nearest the BART tracks and I-680.6 This falls into the County’s normally acceptable to normally unacceptable land use compatibility categories for multi- family residences. Therefore, exterior building assemblies will need to be sound rated to reduce transportation noise to the criteria outlined above. Exterior-to-Interior Noise (GP and CBC) As indicated above, the interior noise criteria are DNL 45 dB in residences due to all outdoor environmental sources, and Lmax 50 and 55 dB, due to BART, in bedrooms and other habitable rooms, respectively. Preliminary estimates show window and exterior door ratings up to STC7 39 will be needed, as shown in Figure 2, attached. These preliminary estimates are based on the following, and will need to be updated based on finalized floor plans, elevations, and window sizes prior to construction. ● Conceptual floor plans and elevations per the P-1 Rezoning Preliminary Final Development Plan dated 25 March 2021 ● Exterior walls will be equivalent to stucco over wood sheeting with batt insulation in stud cavities and at least 1 layer of gypsum board on the interior ● Flooring in bedrooms will be carpet over pad 4 Lmax30 (Typical Maximum Sound Level) – There is no standardized metric to quantify “typical” maximum sound levels in an environment (instead of the absolute maximum sound level for a measurement period). The metric Lmax30 comes from a paper by Rob Greene (“Max Level Intrusive Noise Limit: 1982 National Conference on Environmental and Occupational Noise”). It is based on the logarithmic average of the noisiest 30 percent of single events (e.g., train passbys, aircraft flyovers). 5 The California Department of Transportation assumes a traffic volume increase of three percent per year, which corresponds to a 1 dB increase in DNL over a ten-year period. This should be reviewed when the traffic study for the project is available, as long-term impacts to traffic patterns associated with COVID-19 are not yet known and could affect future environmental noise levels. 6 Estimates are based on noise levels measured at the site along with published levels identified in the Contra Costa County General Plan, Walnut Creek General Plan, Walnut Creek BART Transit Village Draft EIR, and Caltrans traffic counts. 7 STC (Sound Transmission Class) – A single-number rating defined in ASTM E90 that quantifies the airborne sound insulating performance of a partition under laboratory conditions. Increasing STC ratings correspond to improved airborne sound insulation. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 6 Window and door sound insulation ratings must be for the complete tested assembly, including glass and frame, and should be based on laboratory test reports of similar sized samples from an NVLAP accredited lab. For reference, typical construction grade dual-pane windows achieve sound insulation ratings of approximately STC 28. Where no rating is indicated in Figure 2, these ratings are assumed. Ventilation systems must not compromise sound insulation of the exterior wall assemblies. Where windows will need to be closed to meet the interior noise criterion, an alternate means of providing outside air to habitable spaces should be provided. The ventilation systems will need to maintain the exterior-to-interior noise reduction of the overall facade. Details should be developed during the design phase. Outdoor Noise (GP) Conceptual unit plans include 2nd floor decks for some units, and roof decks at units along Oak Road. Following is a discussion comparing levels with the County’s General Plan policies: ● Along Oak Road levels will exceed the County’s DNL 60 dB goal. Therefore, common open space is provided towards the center of the site where transportation noise is consistent with the goal. ● Along Jones Road the measured level at the second story elevation was DNL 67 dB, which is consistent with the County’s goal for outdoor locations exposed to BART noise. Therefore, noise reduction measures are not required. Potential Noise Impacts and Mitigation Measures (CEQA) Overall changes to the noise environment, attributable to the project, include the following: • Project-related traffic increases (permanent) • Potential rooftop mechanical equipment noise (permanent) • Short-term construction noise and vibration (temporary) The following summarizes the portion of the CEQA checklist pertaining to noise. CEQA does not define what noise level increase would be considered significant. Typically, a project is considered to have a significant impact if it would increase DNL by more than 3 dB (the minimum increase generally perceptible to most people) and cause ambient noise levels to exceed the normally acceptable guidelines in the General Plan. Where existing levels are well below the General Plan guidelines, a somewhat higher increase (i.e., 5 dB) may be tolerated before the impact is considered significant. For the purpose of this analysis, an increase exceeding 3 dB is considered significant for permanent noise sources. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 7 Would the project result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? This analysis compares noise from the following long and short-term generators with the CEQA guidelines: project generated traffic and temporary noise from construction activities. Project-Generated Traffic Vehicles will enter and exit the site via driveways on Jones Road and Oak Road. A draft traffic study for the project, titled Transportation Analysis for the Summerhill Homes Townhome Condo Site Residential Redevelopment at 2740 Jones Road in Walnut Creek, California, by Hexagon Transportation Consultants, Inc. and dated 22 March 2021, includes existing and project-generated AM and PM peak-hour traffic volumes at four study intersections in the project vicinity. The intersections are Oak Road and Jones Road, Oak Road and Treat Boulevard, Jones Road and the project driveway, and Oak Road and the project driveway. The intersection volume data indicates that peak hour traffic volumes will increase by 3 percent of less, which corresponds with less than a 1 dB increase in the DNL. Therefore, project-generated traffic will result in a less-than-significant increase. Mechanical Equipment Residences are expected to include outdoor condensing units for air conditioning systems. These will be located at-grade, approximately 15 feet and farther from adjacent off-site residential property lines. Based on the noise levels measured at the site and summarized in Table 2 above, and the allowable increase of up to 3 dB, the cumulative operational noise level from outdoor condensing units shall not exceed DNL 60 dB at adjacent off-site residential receivers. Incorporating the following mitigation measure will ensure this is a less than significant impact. Mitigation Measure 1: Require an acoustic analysis prior to construction confirming that operational noise from outdoor mechanical equipment associated with the project is DNL 60 dB or lower at adjacent off-site residences. Construction Noise Construction of the project is expected to occur over approximately a 36-month period. Noise levels from construction activities will vary, depending on the type of equipment being used, the process, and the location. The loudest phases of construction are expected to be demolition, grading/excavation, and foundations. Table 3, below, provides a list of construction equipment expected to be used in each phase and estimates the phase duration. Table 4 provides reference sound levels for construction equipment at a distance of 50 feet. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 8 Table 3: Construction Equipment and Estimated Phase Duration Phase Equipment Demolition Concrete Saws, Excavators, Rubber-Tired Dozers, Haul Trucks Site Preparation, Rough Grading Rubber-Tired Dozers, Tractors, Loaders, Backhoes Grading, Wet/Dry Utilities Excavators, Graders, Rubber-Tired Dozers, Tractors, Loaders, Backhoes Building Construction Crane, Forklifts, Generator Sets, Tractors, Loaders, Backhoes, Welders Paving Pavers, Paving Equipment, Rollers Architectural Coating Air Compressors Table 4: Typical Construction Equipment Noise Levels8 Equipment Noise Level (dB) at 50 feet Backhoe 80 dB Bulldozer 85 dB Compressor (air) 81 dB Concrete Trucks 85 dB Crane 88 dB Excavator 81 dB Gypcrete Pump 82 dB Plaster Pump 82 dB Pneumatic Tool 85 dB Pumps 77 dB Rebar Saw 76 dB Trucks (traveling) 84 dB The nearest neighboring residential budlings appear to be approximately 20 to 50 feet from the first row of planned homes. Construction-generated noise typically drops off at a rate of approximately 6 dB for each doubling of distance, therefore noise levels from individual construction activities shown in Table 4 may be up to 8 dB louder than shown in the table when working along the building edges nearest the residences. Construction noise will be lower during quieter phases, as homes are built farther from the property line, and as the nearest homes are built and effectively shield remaining construction activities from off-site receivers. Background traffic noise from I-680 and BART trains will help mask construction noise during the quieter phases. The project shall implement the following noise reduction measures to help reduce the impact of construction on neighbors: 8 Based on the Federal Highway Administration document “FHWA Highway Construction Noise Handbook” Tables 7.3 and 9.9, Federal Transit Administration document “Transit Noise and Vibration Impact Assessment” Table 12-1, US EPA document, “Noise from Construction Equipment and Operations, Building Equipment, and Home Appliances” (1971), and data from other Salter construction noise monitoring projects. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 9 1. Construction activities shall be limited to between 7:00 AM and 6:00 PM Monday through Saturday, unless permission is granted with a development permit or other planning approval. Construction will not occur on Sundays and Federal holidays. 2. Construction activity should be conducted to minimize the noise impact at adjacent off-site receivers wherever feasible. 3. Equip all internal combustion engines-driven equipment intake and exhaust mufflers that are in good conditions and appropriate for the equipment. 4. Unnecessary idling of internal combustion engines should be strictly prohibited. 5. Locate stationary noise-generating equipment, such as air compressors or portable power generators, as far as possible from sensitive receptors as feasible. 6. Utilize “quiet” air compressors and other stationary equipment where technology exists. 7. Construction staging areas, including truck loading and unloading operations, shall be scheduled and located so they minimize the noise impact on adjacent off-site residences. 8. Control noise from construction workers' radios to a point where they are not audible at existing residences bordering the project site. 9. Designate a "disturbance coordinator" who would be responsible for responding to any complaints about construction noise. The disturbance coordinator will determine the cause of the noise complaint (e.g., bad muffler, etc.) and will require that reasonable measures be implemented to correct the problem. 10. Conspicuously post a telephone number for the disturbance coordinator at the construction site. Would the project result in generation of excessive ground-borne vibration or ground-borne noise levels? Construction activities may generate temporary ground-borne vibration. The buildings will all be above grade with poured slab on grade construction, and the nearest adjacent off-site receivers are residences located to the north and south approximately 20 feet and farther from the planned homes. The adjacent residences appear to be of normal conventional construction, and we are not aware of specific vibration- sensitive uses or sensitivity of these buildings. As indicated above, construction of the project will include demolition of existing buildings, site preparation and utilities, foundations, and new building framing and finishing, and is expected to use the equipment included in Table 3 above. Published vibration levels for common construction equipment at a reference distance of 25 feet, and corresponding estimated levels at the approximate distance of the nearest adjacent residential buildings, are summarized in Table 5 below.9 9 Reference and estimated levels are based on Table 18 and Equation 12 of the Transportation- and Construction-Induced Vibration Guidance Manual, California Department of Transportation, June 2004. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 10 Table 2: Measured Noise Levels Equipment Reference PPV (in/sec) at 25’ Estimated PPV (in/sec) at 20’ Hoe Ram 0.089 0.114 Large Bulldozer 0.089 0.114 Loaded Trucks 0.076 0.097 Jackhammer 0.035 0.045 Small Bulldozer 0.003 0.004 The document titled Transportation- and Construction-induced Vibration Guidance Manual, by the California Department of Transportation, identifies 0.5 PPV (peak particle velocity in inches per second) as the threshold for continuous and frequent intermittent construction vibration to avoid damage at residential buildings. Construction vibration levels may vary, depending on factors such as soil conditions, construction methods, equipment location, etc., and may be perceptible on adjacent sites. However, the estimated vibration levels in Table 5 above, at the approximate distances of the nearest adjacent off-site residential buildings, are all well below the 0.5 PPV threshold. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? The project site is located over five miles from local airports including Buchanan Field and the Byron Airport. * * * Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 11 APPENDIX A Fundamental Concepts of Environmental Noise This section provides background information to aid in understanding the technical aspects of this report. Three dimensions of environmental noise are important in determining subjective response. These are: • The intensity or level of the sound • The frequency spectrum of the sound • The time-varying character of the sound Airborne sound is a rapid fluctuation of air pressure above and below atmospheric pressure. Sound levels are usually measured and expressed in decibels (dB), with 0 dB corresponding roughly to the threshold of hearing. The "frequency" of a sound refers to the number of complete pressure fluctuations per second in the sound. The unit of measurement is the cycle per second (cps) or hertz (Hz). Most of the sounds, which we hear in the environment, do not consist of a single frequency, but of a broad band of frequencies, differing in level. The name of the frequency and level content of a sound is its sound spectrum. A sound spectrum for engineering purposes is typically described in terms of octave bands, which separate the audible frequency range (for human beings, from about 20 to 20,000 Hz) into ten segments. Many rating methods have been devised to permit comparisons of sounds having quite different spectra. Surprisingly, the simplest method correlates with human response practically as well as the more complex methods. This method consists of evaluating all of the frequencies of a sound in accordance with a weighting that progressively de-emphasizes the importance of frequency components below 1000 Hz and above 5000 Hz. This frequency weighting reflects the fact that human hearing is less sensitive at low frequencies and at extreme high frequencies relative to the mid-range. The weighting system described above is called "A"-weighting, and the level so measured is called the "A- weighted sound level" or "A-weighted noise level." The unit of A-weighted sound level is sometimes abbreviated "dB." In practice, the sound level is conveniently measured using a sound level meter that includes an electrical filter corresponding to the A-weighting characteristic. All U.S. and international standard sound level meters include such a filter. Typical sound levels found in the environment and in industry are shown in Figure A-1. Although a single sound level value may adequately describe environmental noise at any instant in time, community noise levels vary continuously. Most environmental noise is a conglomeration of distant noise sources, which results in a relatively steady background noise having no identifiable source. These distant sources may include traffic, wind in trees, industrial activities, etc. and are relatively constant from moment to moment. As natural forces change or as human activity follows its daily cycle, the sound level may vary slowly from hour to hour. Superimposed on this slowly varying background is a succession of identifiable noisy events of brief duration. These may include nearby activities such as single vehicle pass- bys, aircraft flyovers, etc. which cause the environmental noise level to vary from instant to instant. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 12 To describe the time-varying character of environmental noise, statistical noise descriptors were developed. "L10" is the A-weighted sound level equaled or exceeded during 10 percent of a stated time period. The L10 is considered a good measure of the maximum sound levels caused by discrete noise events. "L50" is the A-weighted sound level that is equaled or exceeded 50 percent of a stated time period; it represents the median sound level. The "L90" is the A-weighted sound level equaled or exceeded during 90 percent of a stated time period and is used to describe the background noise. As it is often cumbersome to quantify the noise environment with a set of statistical descriptors, a single number called the average sound level or "Leq" is now widely used. The term "Leq" originated from the concept of a so-called equivalent sound level which contains the same acoustical energy as a varying sound level during the same time period. In simple but accurate technical language, the Leq is the average A-weighted sound level in a stated time period. The Leq is particularly useful in describing the subjective change in an environment where the source of noise remains the same but there is change in the level of activity. Widening roads and/or increasing traffic are examples of this kind of situation. In determining the daily measure of environmental noise, it is important to account for the different response of people to daytime and nighttime noise. During the nighttime, exterior background noise levels are generally lower than in the daytime; however, most household noise also decreases at night, thus exterior noise intrusions again become noticeable. Further, most people trying to sleep at night are more sensitive to noise. To account for human sensitivity to nighttime noise levels, a special descriptor was developed. The descriptor is called the Ldn (Day/Night Average Sound Level), which represents the 24- hour average sound level with a penalty for noise occurring at night. The Ldn computation divides the 24- hour day into two periods: daytime (7:00 am to 10:00 pm); and nighttime (10:00 pm to 7:00 am). The nighttime sound levels are assigned a 10 dB penalty prior to averaging with daytime hourly sound levels. For highway noise environments, the average noise level during the peak hour traffic volume is approximately equal to the Ldn. The effects of noise on people can be listed in three general categories: • Subjective effects of annoyance, nuisance, dissatisfaction • Interference with activities such as speech, sleep, and learning • Physiological effects such as startle, hearing loss The sound levels associated with environmental noise usually produce effects only in the first two categories. Unfortunately, there has never been a completely predictable measure for the subjective effects of noise nor of the corresponding reactions of annoyance and dissatisfaction. This is primarily because of the wide variation in individual thresholds of annoyance and habituation to noise over time. Thus, an important factor in assessing a person's subjective reaction is to compare the new noise environment to the existing noise environment. In general, the more a new noise exceeds the existing, the less acceptable the new noise will be judged. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 13 With regard to increases in noise level, knowledge of the following relationships will be helpful in understanding the quantitative sections of this report: Except in carefully controlled laboratory experiments, a change of only 1 dB in sound level cannot be perceived. Outside of the laboratory, a 3 dB change is considered a just-noticeable difference. A change in level of at least 5 dB is required before any noticeable change in community response would be expected. A 10 dB change is subjectively heard as approximately a doubling in loudness, and would almost certainly cause an adverse community response. Oak Road Townhouse Condos – Contra Costa County, CA 7 May 2021 DRAFT Environmental Noise Assessment Page 14 A1 Contra Costa County–Oak Road Townhouse Condominiums Project Draft EIR FirstCarbon Solutions Appendix I: Transportation Supporting Information THIS PAGE INTENTIONALLY LEFT BLANK Draft Memorandum Date: May 10, 2021 To: Mr. Marshall Torre, Summerhill Homes From: Jonathan Wong Ollie Zhou Subject: Transportation Analysis for the Summerhill Homes Townhome Condo Site Residential Redevelopment at 2740 Jones Road in Walnut Creek, California Hexagon Transportation Consultants, Inc. has completed a transportation analysis for the proposed Summerhill Homes Townhome Condo Site Residential Development project at 2740 Jones Road in Walnut Creek, California. The project would build 125 residential units on the former private school site. The project site is located between Jones Road and Oak Road (see Figure 1). The site is currently vacant. Access to the site is provided via Jones Road and Oak Road. Vehicle Miles Travelled (VMT) Analysis In December 2018, the California Natural Resources Agency certified and adopted the CEQA Guidelines update package, including the Guidelines section implementing Senate Bill 743. The guidelines state that level of service will no longer be considered to be an environmental impact under CEQA and that vehicle miles travelled (VMT) is the most appropriate measure of transportation impact. SB 743 went into effect on July 1, 2020. In accordance with new CEQA guidelines, the County has transitioned from intersection LOS to vehicle miles travelled (VMT) for CEQA transportation analysis. A project’s VMT is compared to the appropriate thresholds of significance based on the project location and type of development. When assessing a residential project, the project’s VMT is divided by the number of residents expected to occupy the project to determine the VMT per capita. To determine whether a project would result on CEQA transportation impacts related to VMT, the City has established thresholds for residential, office, and retail projects. For residential projects, the significant VMT impact threshold is 85% of existing County-wide average VMT per capita, A project may indicate a significant transportation impact.

These screening criteria are generally based on project size and location. These include: • Projects that: o Generate or attract fewer than 110 daily vehicle trips; or, o Projects of 10,000 square feet or less of non-residential space or 20 residential units or less, or otherwise generating less than 836 VMT per day. • Residential, retail, office projects, or mixed-use projects proposed within ½ mile of an existing major transit stop or an existing stop along a high quality transit corridor. • Residential projects (home-based VMT) at 15% or below the baseline County-wide home- based average VMT per capita, or employment projects (employee VMT) at 15% or below the baseline Bay Area average commute VMT per employee in areas with low VMT that incorporate similar VMT reducing features (i.e., density, mix of uses, transit accessibility). • Public facilities (e.g. emergency services, passive parks (low-intensity recreation, open space), libraries, community centers, public utilities) and government buildings. Project-level VMT Analysis According to the Contra Costa County Transportation Analysis Guidelines, a project is expected to result in a less-than-significant VMT impact if the proposed project is located within ½ mile of an existing major transit stop or an existing stop along a high quality transit corridor. The Pleasant Hill BART station, which is an existing major transit stop, is located within ½ mile of the project site. In addition, there are bicycle and pedestrian facilities between the project site and the Pleasant Hill BART station. There are continuous sidewalks along Jones Road and Oak Road that connects to the project site and the Pleasant Hill BART station. At a normal walking pace, it will take approximately 10 minutes to walk from the project site to the Pleasant Hill BART station. The Iron Horse Regional Trail and the Contra Costa Canal Trail are bicycle facilities that connect the project site to the Pleasant Hill BART station. Bicyclists would travel south on Jones Road or Oak Road to connect to the Contra Costa Canal Trail, heading east. Then bicyclists would travel north along the Iron Horse Regional Trail, which would lead to the Pleasant Hill BART station. There are also bike racks and bike lockers at the BART station for bicyclists to park their bicycles. Furthermore, the BART system provides quality regional connection to major employment destinations within the Bay Area (i.e. Oakland, San Francisco), and would soon connect to the San Jose area as well. The Pleasant Hill BART station also connects to local bus routes that are provided by County Connection. These local bus routes include 7, 9, 11, 14, 15, and 311. It is anticipated that this proposed residential project, being located within close proximity to the BART station, would have many residents take advantage of its regional transit connectivity. This would reduce residents’ need to drive. As the County’s guidelines stated, therefore, the project’s VMT impact is considered less than significant. Transportation Demand Management (TDM) Plan A Transportation Demand Management Plan is prepared as part of this project. The TDM Plan will include a range of TDM measures designed to reduce single-occupant vehicle trips and encourage residents to walk, bike or use transit services.

Oak Road and Project Driveway Note that the traffic volumes collected are adjusted to pre-COVID conditions. The intersection at Oak Road and Treat Boulevard had historic counts in year 2018. A factor was derived by comparing the historic counts to the newly collected (2021) counts. This factor was applied to all other intersections to derive pre-COVID volume estimates. Since the pre-COVID count was dated for year 2018, Hexagon derived an annual growth rate using counts at this intersection collected in 2014. This annual growth rate was then applied to all intersection volumes to bring the 2018 counts/derived volumes to 2021 conditions as if there was no COVID (see Table 1 for calculations of COVID factors, Table 2 for calculations of growth rates and Table 3 for a comparison). This represents a conservative analysis. Further factoring were conducted at the Oak Road and Jones Road intersection to ensure volume balancing on the north leg with the intersection at Oak Road and Treat Boulevard. The existing school driveway traffic volumes were estimated based on the trip rates published in the Institute of Transportation Engineers’ (ITE) Trip Generation Manual, 10th Edition (2017) for Private School (K-8). The Oak Road/Project Driveway traffic volumes were taken from the Oak Road/Jones Road intersection. Figure 2 shows the existing traffic volumes at the study intersections.

In determining project trip generation, the magnitude of traffic entering and exiting the site is estimated for the AM and PM peak hours. As part of the project trip distribution, an estimate is made of the directions to and from which the project trips would travel. In the project trip assignment, the project trips are assigned to specific streets and intersections. These procedures are described below. Project Trip Generation Proposed Project Trip generation Vehicle trips generated by the proposed residential component of the project were estimated using the trip rates published in the Institute of Transportation Engineers’ (ITE) Trip Generation Manual, 10th Edition (2017) for “Single Family Detached Housing” (Land Use 210). Since the proposed units all included at least three bedrooms with their own attached garages, it was determined that the single family detached housing land use would best reflect the trip generation characteristic for the proposed project. It should be noted that the single family rates are also the highest trip generation rates out of all residential trip rates. This analysis thus represents a slightly conservative analysis. As shown in the Table 4, the project is estimated to generate 1,180 gross daily vehicle trips, with 93 gross trips occurring during the AM peak hour and 124 gross trips during the PM peak hour. Existing Trip Credits Trips generated by the existing uses on the site can be credited against the proposed development. At the time of this report, the former private school is permanently closed. However, the school is being credited because this traffic study is analyzed under pre-COVID conditions when the school was open. The existing traffic counts, as discussed earlier, are all factored to pre-COVID conditions. The private school trip generation estimates are based on ITE rates for Private School (K-8). According to the former school owner, the school had student enrollments ranging between 370 students and 400 students. The school also had after-school activities and was open until 6 PM on school days. For a conservative analysis, the school is credited using the 370 students. When comparing the PM peak hour rate to other private/charter elementary and middle schools (average of 0.56 trips per student), the ITE rate of 0.26 trips per student for the PM peak hour appeared low. Table 5 provides a PM peak hour trip rate of elementary and middle schools similar to the existing school. Therefore, crediting school’s PM trip generation using the ITE trip rates represent a conservative analysis. It is estimated that the private school with 370 students would have generated 1,521 daily trips with 337 trips during the AM peak hour and 96 trips during the PM peak hour. Net Project Trips After accounting for the trips generated by the former private school, the proposed residential project is estimated to generate a net decrease of 341 daily trips, with a net decrease of 244 trips in the AM peak hour and a net increase of 28 trips in the peak hour. It should be noted that this analysis represented a conservative analysis. Crediting the project with even the lowest observed PM rates for comparable schools would have resulted in an overall net decrease in trips.

The peak-hour trips generated by the existing and proposed uses were assigned to the roadway system based on the directions of approach and departure, the roadway network connections, and the locations of project driveways. The trips generated by the existing uses were subtracted from the roadway network prior to assigning project trips. It should be noted that the school trips were only accessed on one driveway on Jones Road. It is assumed that all residential trips would enter and exit the project site via two driveways each on Jones Road and on Oak Road. Figure 3 shows the trip distribution and assignment of the project.

The development project generates 100 or more net new peak hour vehicle trips; or 2. The development project adds 50 or more net new peak hour vehicle trips to an intersection; or 3. A project creates safety or operation concerns. While the project does not meet any of the three requirements, a level of service analysis of existing and existing plus project conditions is performed. As the analysis below shows, the project would generate minimal increase in average delays to study intersections. This is largely because in a pre-COVID environment, the trips generated by the proposed project would be largely offset by the trip credits of the Palmer school. The number of net new trips added to the intersections would be minimal. As a result, the project’s effect on intersection operations would also be minimal. It is thus not expected that the project would have any considerable effects on intersection operations under background or cumulative conditions. County of Contra Costa Intersections According to County of Contra Costa level of service standard, a development is said to create operational deficiencies on traffic conditions at a studied intersection if: 1. The level of service at the intersection drops below its respective level of service standard (LOS D or better), or 2. The intersection is an unacceptable level of service (LOS E or F) and the addition of project trips cause the average control delay (for signalized and all-way stop-controlled intersections) or worst movement/approach delay (for side-street stop-controlled intersections) at the intersection to increase by more than 5.0 seconds. Intersection Operations The study intersections were evaluated for level of service. Level of Service is a qualitative description of operating conditions ranging from LOS A, or free-flow conditions with little or no delay, to LOS F, or jammed conditions with excessive delays. The Contra Costa County level of service methodology for signalized intersections is the Highway Capacity Manual (HCM) 6th Edition method. This method is applied using the Synchro software. The HCM 6th operations method evaluates signalized intersection operations on the basis of average control delay time for all vehicles at the intersection. The HCM 6th operations method evaluates unsignalized intersection operations on the basis of worst approach delay. The Contra Costa County level of service standard for signalized and unsignalized intersections is LOS D or better. Level of Service Analysis Results The results of the level of service analysis show that all four study intersections currently operate at an acceptable LOS D or better, and the project would have a minimal effect on the existing intersection operations (see Table 6). Summerhill Homes Townhome Condo Project May 10, 2021 P a g e | 12 Table 6 Intersection Levels of Service Site Circulation and Access A review of the project site plan was performed to determine whether adequate site access and in- site circulation would be provided, using commonly accepted transportation planning principles and traffic engineering standards. This review was based on the site plan prepared by SDG Architects, Inc. dated January 29, 2021, shown on Figure 4. Hexagon has also reviewed the site plan being prepared for the next round of submittal at the time of this report. Avg.Avg.

Figure 4 Proposed Site Plan Summerhill Homes Townhome Condo Project Summerhill Homes Townhome Condo Project May 10, 2021 P a g e | 14 Site Access Vehicle site access was evaluated to determine the adequacy of the site driveways. The project generated traffic would access the site via a new driveway connecting to Jones Road. There will also be a proposed driveway that will connect to the project site on Oak Road. The new driveway on Jones Road will be 26 feet wide, which can accommodate two-way traffic. The site plan shows that the Oak Road driveway would be approximately 26 feet. The 26 feet driveway width would be adequate for emergency vehicle access. Sight Distance Sight distance was evaluated to determine if a driver will have adequate visibility to enter Jones Road and Oak Road from the driveways. The project access points should be free and clear of any obstructions that would materially and adversely affect sight distance, thereby ensuring that exiting vehicles can see pedestrians on the sidewalk and other vehicles travelling on adjacent roadways. Landscaping and parking should not conflict with a driver’s ability to locate a gap in traffic and see oncoming pedestrians and bicyclists. Adequate corner sight distance (sight distance triangles) should be provided at all site access points in accordance with the County standards. Sight distance requirements vary depending on the roadway speeds. The speed limit on Jones Road and Oak Road is 35 mph. According to the Highway Design Manual (HDM), Chapter 200, 2014, the required minimum stopping sight distance for design speed of 35 mph is 250 feet. The line of sight for vehicles exiting the driveway and vehicles travelling northbound on Jones Road are clear and visible. Vehicles exiting the driveway will be visible to the vehicles travelling southbound on Jones Road and Oak Road. There are existing red curbs on both sides of each driveway to provide adequate visibility for vehicles exiting the project site. The project would not substantially increase hazards due to any design features. On-site Circulation On-site circulation was reviewed in accordance with generally accepted traffic engineering standards. The project would provide new streets and alleys within the project site that lead to each unit. Each unit would have its own driveway and a garage. According to the Contra Costa County Municipal Code, the minimum two-way drive aisle width for multifamily uses is 20 feet and 26 feet when portion of the building has human occupancy located more than 30 feet above the access road. The site plan shows the appropriate drive aisle widths within the project site. The site plan would provide adequate space for garbage trucks, loading trucks and emergency vehicles to circulate throughout the project site. Summerhill Homes Townhome Condo Project May 10, 2021 P a g e | 15 Bicycle, Pedestrian and Transit Facilities Evaluation Bicycle Facilities Currently, there are no existing bike lanes on Jones Road. However, there is a pedestrian/bike trail, Iron Horse Regional Trail, located approximately 1,500 feet east of the project site. The bike trail provides access to the Pleasant Hill BART station. There is also another pedestrian/bike trail, Contra Costa Canal Trail, located approximately 650 feet south of the project site and crossing Jones Road. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. The project would not affect existing and planned bicycle facilities. The project also proposes to include a bike repair space on site. The Seven Hills School is located within a 3-mile radius of the project site. The Contra Costa Canal Trail provides a good bicycle connectivity to the project site and the Seven Hills School. Oak Road has planned Class II facilities in the vicinity of the project. The planned Class facilities is located on Oak Road between Treat Boulevard and the Contra Costa Canal Trail. The four on- street parking spaces proposed along Oak Road would not result in a conflict with future construction of this facility. The Iron Horse Regional Trail, a pedestrian/bike trail, located approximately 1,500 feet east of the project site. The Iron Horse Regional Trail extends from Marsh Drive in Concord to DeMarcus Boulevard in Dublin. The Iron Horse Regional Trail provides access to the Pleasant Hill BART station. There is also another trail, Contra Costa Canal Trail, located approximately 650 feet south of the project site and crossing Jones Road. The Contra Costa Canal Trail extends from Muir Road in Martinez to Willow Pass Road in Concord. The Contra Costa Canal Trail provides access to Walden Park and the Iron Horse Regional Trail. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. Figure 5 shows the existing bicycle facilities within the project area. Pedestrian Facilities There are sidewalks on the east side of Jones Road within the vicinity of the project site. There are also sidewalks on both sides of Oak Road and Treat Boulevard so that residents at the project site can easily walk to the Pleasant Hill BART station. The traffic signal at the Oak Road/Jones Road and Oak Road/Treat Boulevard intersections includes crosswalks with pedestrian signal heads to facilitate crossing the street. The Iron Horse Regional Trail and Contra Costa Canal Trial described above are Class I pedestrian/bicycle facilities within project proximity. There are no pedestrian improvement plans along Jones Road or Oak Road along the project frontage. The project would not affect existing or planned pedestrian facilities. The Seven Hills School is located within a 1-mile radius of the project site. Although the Contra Costa Canal Trail provides a pedestrian connectivity between the two locations, it is not likely for a pedestrian to walk further than a 1-mile. Summerhill Homes Townhome Condo Project May 10, 2021 P a g e | 16 Transit Facilities The site is served by several County Connection bus routes: 7, 9, 11, 14, 15, and 311. The project site is located with ½ mile of a major transit stop, the Pleasant Hill BART station, which is located north of the project site. The closest bus stop to the project site is located at Oak Road and Walden Park, approximately 970 feet south of the project site. There are sidewalks on Oak Road that provide connectivity to the bus stop. The Pleasant Hill BART station also provides other bus route connections in addition to other County Connection lines. AC Transit, Solano Express, Fairfield and Suisun Transit, and Wheels Express provide connecting transit routes at the Pleasant Hill BART station (see Figure 6 and Table 7 below). Paratransit services could also be provided to the residents at the project site. County Connection LINK serves Pleasant Hill, Walnut Creek, Concord, Lafayette and other central Contra Costa cities. Paratransit service rides are provided within 1.5 miles of a bus stop or train station.

According to the Contra Costa County Municipal Code, the vehicle requirement for a townhouse is 2 covered spaces per unit. In addition, the guest parking requirement is 0.25 spaces per unit. The project proposes to construct 125 units. Therefore, the project is required to provide 250 residential parking spaces and 32 guest parking spaces, which totals 282 parking spaces. The site plan shows that a 2-car garage parking will be provided in each townhome and 28 guest parking spaces within the project site.

Therefore, each townhome should provide a dedicated 208/240-volt branch circuit. In addition, the site proposes to add 4 on-street frontage parking spaces along Oak Road. The combination of guest parking onsite and new on-street parking will suffice the requirement for guest parking. The parking standards do not require any loading spaces to be provided. According to the County Municipal Code, the short-term bicycle parking requirement for townhomes with private garages is five percent of the number of bedrooms, or two spaces, whichever is greater. There is no space requirement for long-term bicycle parking. Each townhouse would have 3 bedrooms. Therefore, the project is required to provide 0.15 short-term bicycle spaces per townhouse, which totals to 19 short-term bicycle parking spaces. The project would provide bicycle racks around the site. The bicycle racks are located between Buildings P and Q, Buildings Q and R, Buildings R and S and Buildings D and E. The bike racks between Buildings R and S would have 9 racks while the other locations would have 4 racks. With each bike rack providing 2 bicycle parking spaces, the project would provide 42 bicycle parking spaces, exceeding the County requirement. The project also proposes to include a bike repair space on site next to the short-term bike racks.

Carpenter (CARPENTER) Response to CARPENTER-1 The commenter states that there are numerous vacancies in the immediate neighborhood of the proposed project. The commenter concludes that fully publicly funded housing for street residents is likely the only reasonable construction in the near future. The comment is noted. As stated on page 2-5 of the Draft EIR, two of the proposed project ’s objectives are to develop an appropriate mix of multi-family units, including affordable units, that meets the existing General Plan land use designation and regional housing goals; and to provide affordable housing units in accordance with the Contra Costa County Housing Element. As such, 10 inclusionary housing units would be provided to moderate-income households and the applicant would pay the in-lieu fee for 8.75 inclusionary housing units. In addition, as stated on page 2-3 of the Draft EIR, the project site’s land use designation is Multiple- Family Residential–High Density (MH) according to the Contra Costa General Plan. The MH designation allows for densities between 22.0 and 29.9 multiple-family units per net acre, with residential units up to 1,979 square feet. Primary land uses allowed within this designation include attached single-family residences (such as duplexes or duets), multiple-family residences such as condominiums, townhouses, apartments, and mobile home parks, and accessory buildings and structures normally auxiliary to the primary uses. Secondary land uses that do not conflict with primary uses may also be allowed, including churches, accessory dwelling units, home occupations, and group care and/or childcare facilities. The Contra Costa zoning map identifies three residential zoning designations for the project site: Single-Family Residential (R-15), Multiple-Family Residential (M-17), and Multiple-Family Residential (M-29). As described on page 2-7 of the Draft EIR, as part of project approvals, the applicant is requesting rezoning of the site to Planned Unit District (P-1). The P-1 Zoning District is intended to support large-scale integrated development in compliance with the General Plan designations. The proposed project would be consistent with the P-1 Zoning District Development Standards shown in Table 2-3, which are based on Section 84-66.602 of the Ordinance Code. As stated on page 3.10-27 of the Draft EIR, the P-1 zoning would allow flexibility with respect to use, building types, lot size, and open space while ensuring the proposed project complies with the General Plan and requirements as set forth in the Ordinance Code. It also allows necessary public health and safety standards to be observed without inhibiting large-scale development. Furthermore, as described on page 3.1-11 of the Draft EIR, the proposed project would be consistent with the Design Objectives identified in Section 84- 66.1402 of the Ordinance Code related to the P-1 Zoning District. For example, the buildings bulk, height, land coverage, and visual appearance is compatible with existing adjoining development. In addition, the design of the buildings provides for harmonious composition of mass, scale, color, and textures. The comment stating that fully publicly funded housing is the only reasonable construction in the near future is not related to the adequacy of the Draft EIR. However, it will be forwarded to decision- makers for their consideration.

Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 4 of 21 C. California Environmental Quality Act (CEQA) Compliance: The Department of Conservation and Development, Community Development Division (CDD) determined that an EIR was required for the project and distributed a Notice of Preparation (NOP) on April 28, 2021. The Draft EIR (DEIR) was released for public review on October 21, 2021 and was available for public review and comment for a period of 45 days, through December 6, 2021. The Final EIR was published and made available for public review on January 12, 2022. The EIR identifies potentially significant environmental impacts that would occur if the project were implemented and identifies mitigation measures that would reduce potentially significant impacts to less than significant levels. The recommended mitigation measures are included within the Mitigation Monitoring and Reporting Plan, which describes the timing and responsible agency for monitoring compliance with all mitigation measures. The mitigation measures have also been incorporated into the recommended conditions of approval. IV. SITE/AREA DESCRIPTION Surrounding Land Uses: The project site is surrounded to the east by the City of Walnut Creek, to the north by unincorporated County, to the west by I-680 and the City of Walnut Creek beyond it, and south by unincorporated County, the Contra Costa Canal, and the City of Walnut Creek. The project site is bound by residential uses to the north and south, by Oak Road to the east with residential uses across Oak Road, and by Jones Road to the west and north. Office uses are located north of Jones Road, while I-680 is located directly 180 feet west of Jones Road. The Contra Costa Canal is approximately 470 feet south of the project site. The nearest Bay Area Rapid Transit (BART) station (Pleasant Hill/Contra Costa Centre Station) is located approximately 0.25-mile northeast of the site. Site Description: The 5.94-acre project site is relatively flat (approximately 90 to 95 feet above mean sea level), with a topographic gradient that slopes gently to the northeast. The project site consists of eight parcels and is developed with structures associated with the former Palmer School for Boys and Girls, a private K- 8 school for approximately 400 students that operated from 1939 until its closure Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 5 of 21 in June 2020. The former school consists of 14 vacant buildings as well as associated structures, including classrooms, an auditorium, a front office, a paved courtyard, a grass field, tennis courts, basketball courts playgrounds, a swimming pool, parking lots and planters. Multiple storage sheds are present on the school site. A landscaped area is located behind the classrooms along the southern boundary of the property and includes planter boxes, storm drain lines, power boxes, and a partially uncovered pipe that appears to be related to storm drainage. In the southeast corner of the property is a 2-story auditorium formerly used as a storage area, containing a kitchen, stage, water heater, and empty storage rooms on the second floor. Several of the existing structures in the northern portion of the project site have been associated with residential uses, including those at 2771, 2747, and 2751 Oak Road. To the east of these buildings is an unpaved lot and a paved driveway. These units are occupied by the property owners’ family members who provide caretaker security services for the property and existing improvements. These units will be vacated in conjunction with the applicant’s acquisition of the property. No other buildings are occupied and are vacant. V. PROJECT DESCRIPTION The proposed project includes rezoning of the project site from Multiple-Family Residential (M-17 and M-29) and Single-Family Residential (R-15) to a Planned Unit District (P-1) and approval of a vesting tentative map reconfiguring the current eight parcels into 19 new residential (common) lots and 11 private roadway lots. The proposed project would involve a development plan to allow the demolition of all existing improvements currently present on-site, including buildings, foundations, asphalt, concrete, fence poles, and landscaping to allow the construction of 19 new three-story buildings containing 125 condominium units. The major project components includes the following: approximately 237,697 square feet of new residential living area (293,507 total gross building square feet), approximately 92,120 square feet of landscaped area, the removal of approximately 74 trees, relocation of one tree, and work within the dripline of approximately six trees, 278 on-site parking spaces and 34 bicycles spaces, internal street, courts, walkways, and drainage improvements, and construction of off-site improvements that includes frontage sidewalk, driveway curb, gutter improvements including retaining existing on-street parking and street tree planting. The project will Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 6 of 21 involve grading of approximately 9,300 cubic yards of cut and approximately 8,700 cubic yards of fill. Residential Uses The proposed 19 buildings will be approximately 293,507 gross square feet, covering approximately 127,768 square feet (or 50 percent) of the 5.94-acre site.

The project proposes a total of approximately 92,120 square feet of landscaped area (25 percent of the site), including a central open space area, paseo/walkways, and a dog park. The outdoor recreation area includes a turf area between Buildings P, Q, R, and S, which also includes benches and tables between Buildings Q and S. There is also another area with benches and tables located between Buildings D and E. The dog park will be located on the northwestern corner of the project site, directly north of Building C. Circulation and Access Jones Road and Oak Road border the project site. Jones Road is a two-lane public street that runs north/south along the site’s western boundary. Oak Road is a four- lane public street that runs north/south along the site’s eastern boundary. Primary access to the site would be from two driveways: one along Jones Road and one along Oak Road. Two parking slots between Buildings D and E would be designated as ADA parking. Fire access routes, providing 25-foot inside turning radii and 45-foot outside turning radii, would be provided through the internal loop roads around the central buildings (Buildings P, Q, R, and S). Emergency vehicle access would be provided via the two proposed driveways on Jones Road and Oak Road. Building Design and Height The proposed project includes 19 three-story buildings, including three buildings on Oak Road with roof decks. Building height will range from 37 feet to a maximum of 43 feet; buildings with a roof-top deck may extend up to 45 feet in height. The buildings will be setback 15 feet from Jones Road and 10 feet from Oak Road. Exterior features of the buildings would include board and batten sidings, horizontal fiber cement lap siding, exterior stucco, architectural composition Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 8 of 21 roofing shingles, metal awnings, vinyl windows, and painted metal railing. The exterior color palate would be comprised of whites and grays. Lighting and Signage A monument sign is proposed at the entrance from Oak Road. The monument sign would include metal letters atop a 4-foot wall with a stone veneer finish. An 11- foot-tall structure, with pitched roof and siding matching the general architecture of the residential buildings, would be installed adjoining this wall, and a plaque with the Oak Road logo would be installed on this structure. Proposed lighting would include exterior lighting for the buildings and pole- mounted lighting throughout the parking areas. Specifically, exterior lighting would include four new streetlights along the Oak Road frontage, matching existing streetlights along this street; eight private street pole lights near the two project entrances and along the public streets and sidewalks, approximately 20 feet tall with shielding to direct lighting downward; forty 3.5-foot bollard lights strategically located throughout the site along pathways, common open space and paseos; and 125 wall pack lights above the garages for each home, to illuminate the driveways. Additionally, each of the 125 residential units would have a front porch light. VI. AGENCY COMMENTS A.

General Plan Consistency Density: The project is located within the unincorporated Walnut Creek community, where the surrounding uses are primarily of residential developments and office uses. The vesting tentative map would subdivide the 5.94-acre project site into 19 residential lots to construct 19 buildings for a total of 125 townhouse condominium units. The project is consistent with the proposed General Plan land use designation of Multiple-Family Residential- Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 13 of 21 High Density (MH), which allows 22.0 – 29.9 units per net acre. The net acreage for the 5.94-acre site is 4.71 acres. The project to construct 125 units allows a density of 26.5 units per net acre, which results in a density of within the MH density range. Goals and Policies The project is consistent with the following Growth Management, 65/35 Land Preservation Standard, Urban Limit Line policies:  Policy 3-5: New development within unincorporated areas of the county may be approved, providing growth management standards and criteria are met or can be assured of being met prior to issuance of building permits in accordance with the Growth Management Program.  Policy 3-8: Infilling of already developed areas shall be encouraged. Proposals that would prematurely extend development into areas lacking requisite services, facilities, and infrastructure shall be opposed. In accommodating new development, preference shall generally be given to vacant or underused sites within urbanized areas, which have necessary utilities installed with available remaining capacity, before undeveloped suburban lands are utilized.  Policy 3-22. Housing opportunities for all income levels shall be created. Fair affordable housing opportunities should exist for all economic segments of the county. The project site is located within the Urban Limit Line (ULL) and is designated for future urban uses. The project is an infill development, since it is surrounded primarily by other residential development and the project site has the necessary utility connections. Further, the project provides 10 moderate-income units. The following Transportation Goals and Policies of the County’s Transportation Element also supports the project. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 14 of 21  Goal 5-I: To encourage use of transit.  Goal 5-K: To provide basic accessibility to all residents, which includes access to emergency services, public services and utilities, health care, food and clothing, education and employment, mail and package distribution, freight delivery, and a certain amount of social and recreational activities.  Goal 5-L: To reduce greenhouse gas emissions from transportation sources through provision of transit, bicycle, and pedestrian facilities.  Policy 5-13: The use of pedestrian and bicycle facilities shall be encouraged. Proper facilities shall be designed to accommodate bikes, pedestrians, and transit.  Policy 5-16: Curbs and sidewalks shall be provided in appropriate areas.  Policy 5-17: Emergency response vehicles shall be accommodated in development project design.  Policy 5-18: The design and the scheduling of improvements to arterials and collectors shall give priority to intermodal safety over other factors including capacity.  Policy 5-24: Use of alternative forms of transportation, such as transit, bike and pedestrian modes, shall be encouraged in order to provide basic accessibility to those without access to a personal automobile and to help minimize automobile congestion and air pollution. The project site is located approximately 0.25 miles south of the Pleasant Hill/Contra Costa Centre BART Station, which also serves as a bus transit hub. The Iron Horse Regional Trail, which is a is a pedestrian/bike trail, located approximately 1,500 feet east of the project site. The bike trail provides access to the Pleasant Hill/Contra Costa Centre BART station. There is also another Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 15 of 21 pedestrian/bike trail, Contra Costa Canal Trail, located approximately 450–600 feet south of the project site and crossing Oak Road and Jones Road. The project would provide 34 bicycle parking spaces. The project also proposes to include a bike repair space on-site. Primary access to the site would be from two driveways: one along Jones Road and one along Oak Road. Fire access routes, providing 25-foot inside turning radii and 45-foot outside turning radii, would be provided through the internal loop roads around the central buildings (Buildings P, Q, R, and S). Emergency vehicle access would be provided via the two proposed driveways on Jones Road and Oak Road. The project is also consistent with the following Housing Goal and Policy of the County’s Housing Element.  GOAL 1: Maintain and improve the quality of the existing housing stock and residential neighborhoods in Contra Costa County.  GOAL 3: Increase the supply of housing with a priority on the development of affordable housing, including housing affordable to extremely-low income households.  Policy 3.1: Support the development of additional affordable housing by non-profit and for-profit developers through financial assistance and/or regulatory incentives such as density bonus or flexible development standards through planned unit development.  Policy 3.3: Increase the supply of affordable housing and encourage the development of mixed-income housing through the Inclusionary Housing Ordinance.  GOAL 6: Provide adequate sites through appropriate land use and zoning designations to accommodate the County’s share of regional housing needs. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 16 of 21 The project site is located approximately 0.25-miles south of the Pleasant Hill/Contra Costa Centre BART Station and will provide 125-units near transit. Of the 125-residential units, the development would include 10 moderate- income units. Overall, the project would be consistent with the transit-oriented residential character of the surrounding area. Housing Element Compliance: A component of preparing the County’s Housing Element for the General Plan is the identification of vacant and underutilized sites suitable for residential development, and an evaluation of the housing development potential of these sites in fulfilling the County’s share of the regional housing needs as determined by the Association of Bay Area Governments (ABAG). The project site is not listed on the housing inventory list as a site that was previously identified for future housing development. However, the project itself is a residential development that will add to the housing inventory for the county. B. Zoning Compliance: The project site is located within the Multiple-Family Residential (M-29 and M-17) and Single-Family Residential (R-15) Zoning Districts. The project includes a rezoning of the 5.94-acre site to P-1. The P-1 zoning district allows flexibility with respect to use, building types, lot size, and open space, while ensuring the project complies with the County’s General Plan and requirements of the County’s Ordinance. The project is a multi-family residential infill development, which will be in harmony with the surrounding multi-family residential and transit-oriented developments. Since the proposed project involves a rezone to a P-1 District, the design standards are evaluated on the proposed project. The buildings will be setback 15 feet from Jones Road and 10 feet from Oak Road. In order to address comments from the adjacent property owners directly northeast of the project site, the applicant has provided a greater setback than initially proposed. Buildings G and H abuts this northeastern residential development and will be setback approximately 26 feet. The buildings located along the southern property line will be at a minimum 15 feet. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 17 of 21 The proposed three-story residential development is a modern farmhouse style design consisting of stucco siding, horizontal lap siding, and board and batt siding. The building includes vinyl windows and composition roofing shingles. Architectural features also include corbels and metal awnings. The proposed townhouse condominium buildings will be 37 feet to a maximum of 43 feet tall, except for the buildings fronting Oak Road, which contains roof decks. The height for the buildings with roof decks is 45 feet tall. Overall, the project is consistent with the established neighborhood providing additional housing stock to the area. C. Stormwater Management and Discharge Control Ordinance: A Stormwater Control Plan (SWCP) is required for projects that will create and/or redevelop impervious surface area exceeding 10,000 square feet in compliance with the County’s Stormwater Management and Discharge Control Ordinance (§1014) and the County’s Municipal Separate Storm Sewer System (MS4) National Pollutant Discharge Elimination System (NPDES) Permit. The applicant has provided a preliminary SWCP and is deemed preliminary complete. This project alters more than 50 percent of the impervious surface of the previously existing development and is greater than one-acre of impervious area, therefore hydromodification is required for this development. Based on the SWCP exhibit the site will be divided into 34 Drainage Management Areas (DMA). Each DMA will be treated by a separate bio retention basin and flow into hydromodification vaults before discharging into storm drains in Jones Road and Oak Road. Provision C.10, Trash Load Reduction, of the County’s NPDES Permit requires control of trash in local waterways. To prevent or remove trash loads from municipal storm drain systems, trash capture devices shall be installed in catch basins (excludes those located within a bioretention/stormwater treatment facility). The devices must meet the County’s NPDES Permit and approved by Public Works Department. The location must be approved by Public Works Department. D. Drainage: Division 914 of the County Ordinance Code requires that all storm Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 18 of 21 water entering and/or originating on this property to be collected and conveyed, without diversion and within an adequate storm drainage system, to an adequate natural watercourse having a definable bed and banks or to an existing adequate public storm drainage system which conveys the storm water to an adequate natural watercourse. The project site is relatively flat, sloping gently northeast. Site drainage as proposed is directed to C.3 facilities and then conveyed to existing drainage lines along Jones Road and Oak Road. A preliminary drainage study was provided for the referenced site plan. The site drainage may have to be revised to accommodate for the treatment of the proposed private roads. E. Traffic and Circulation: Primary vehicle access to the project site would be from The site has frontage along both Jones Road and Oak Road, both publicly maintained roads. Jones Road is a County maintained road and is constructed to its ultimate pavement width of 40 feet within a 60-foot right-of-way. The property’s frontage on Oak Road coincides with the city limit line of Walnut Creek. Oak Road has four through travel lanes and a 2-way left turn lane in the middle of the street. Jones Road has a single travel lane in each direction. Both Oak Road and Jones Road are fully developed and require no additional right of way. As proposed, the site will have 26-foot-wide driveway accesses along Jones Road and Oak Road. The two driveways are connected via an internal private roadway network. The private roads Street A, Street B, Street C, and Street D are 26 feet paved within 27 feet of right-of-way. The site also includes private courts servicing the proposed condominiums. The private courts are 20 feet paved within 21 feet of right-of-way with parking stalls at the terminus of each court. The project will be required to widen the pavement width at the terminus of the private courts to 25 feet to accommodate local traffic turning movements. Fire turnarounds at the end of the courts are not required subject to Fire District approval. The project will provide a reduced minimum curb grade of 0.6% under this application and the according to County Code Section 98-6.004, the Public Works Department supports and authorizes the reduction of the minimum uniform grade of 0.6%. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 19 of 21 The project will include construction of an internal sidewalk system to be located in the common areas of the property. For the portions of sidewalks along the private roads as shown on the development plans, the applicant will be required to construct a 5-foot sidewalk (measured from face of curb). Additionally, the applicant will be required to construct 10-foot sidewalks (measured from face of curb) along the frontage of Jones Road and Oak Road as shown on the Vesting Tentative Map. F. Parking: The project will provide a total of 272 on-site parking spaces with available spaces along the street frontage. Approximately 119 units will consist of a two-car garage and six units will consist of a one-car garage. The units with a one-car garage will also have a dedicated parking space on-site as a second parking space. CCC Ordinance Section 82-16.412 sets forth the amounts of long-term and short-term bicycle parking that a project must provide. The County Code requires only short-term parking spaces for a multiple-family dwelling with private garages to provide space for 5 percent of the number of bedrooms, or two spaces (whichever is greater). The project would be required to provide 23 short-term bicycle spaces. The project provides approximately 34 bicycle spaces. G. Trees: The project site contains 81 trees, representing 21 species. Trees are clustered in the northern, eastern, and southern portions of the site. The most abundant species on-site include 27 coast redwoods (Sequoia sempervirens), nine valley oaks (Quercus lobata), and eight glossy privets (Ligustrum japonicum). A total of 74 trees would be removed as part of project implementation, one tree would be relocated, and six off-site trees would be preserved. Tree #77, a 73-inch Valley Oak located south of Building G is identified to be removed. However, the applicant has indicated every effort will be made to save this tree. Tree #83, a 13-inch Valley Oak located at the project entrance on Jones Road will be relocated on-site. However, the location has not been identified. A condition of approval (COA) #19 will require a replanting of 150 trees, 24-inch boxed trees and a restitution for these replanted trees. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 20 of 21 Additionally, COA #21 requires a contingency bond to ensure that the trees identified to be preserved would remain in a healthy condition after the construction. H. Landscaping: The project proposes a total of approximately 92,120 square feet of landscaped area (25 percent of the site), including a central open space area, paseo/walkways, a dog park, and private yards. Internal courtyards between buildings would be lined with trees, and the central open space would be surrounded by trees. Trees would also be installed along all sides of the project site boundary, including a combination of evergreen screen trees and flowering accent trees of varying sizes. Street trees will also be planted along Oak Road. A final landscape plan will be required and the landscaping for the project will be required to comply with the State’s Model Water Efficient Landscaping Ordinance. I. Lighting District Annexation: The subject property has not been annexed into the lighting district. The property owner will be required, as a condition of approval, to annex into the Community Facilities District (CFD) 2010-1 formed for the Countywide Street Light Financing. IX. CONCLUSION The proposed project is consistent with applicable goals and policies of the General Plan, and also with the intent of the MH General Plan designation and the P-1 Zoning district. The project is an underutilized site that is near transit, the Iron Horse Regional Trail and the Contra Costa Canal Trail, and office and commercial uses nearby. Overall, the project is consistent with the established surrounding area. The design and use of the project site for townhouse condominium units is consistent with the other uses in the immediate area. The project provides additional housing near transit and also provides affordable housing units. Nearly all environmental impacts would be mitigated to a less-than-significant levels. Therefore, staff recommends that the County Planning Commission approve portions of the project that fall under their purview and recommend approval of the project to the Boards of Supervisors for the remaining project elements.

The possible findings are: (a) Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effect as identified in the Final EIR (hereinafter referred to as “finding (1)”). (b) Such changes or alterations are within the responsibility and jurisdiction of another public agency and not the agency making the finding. Such changes have been adopted by such other agency or can and should be adopted by such other agency (hereinafter referred to as “finding (2)”). (c) Specific economic, legal, social, technological or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the Final EIR (hereinafter referred to as “finding (3)”). The required findings shall be supported by substantial evidence in the record. (Guidelines, § 15091). All significant and potentially significant impacts identified in the Draft EIR can be reduced to levels of insignificance through mitigation measures identified in the Draft EIR. The Final EIR incorporates the Draft EIR. References here within to the “EIR” are to the collective documentation contained in the Draft EIR and Final EIR. 1.2 - Statement of Findings An Environmental Impact Report (EIR) pursuant to CEQA has been prepared by Contra Costa County (Lead Agency). The Draft EIR for the Oak Road Townhouse Condominiums Project (proposed project) identifies significant effects on the environment which may occur as a result of the proposed project. Sections 1.5 and 1.6 set forth potential environmental effects of the proposed project which are not significant because of the design of the proposed project or which can feasibly be mitigated below a level of significance. Section 1.8 summarizes the alternatives discussed in the EIR and makes findings with respect to the feasibility of alternatives and whether the alternatives would lessen the significant environmental effects of the proposed project.

In the event of any inconsistencies, the MMRP shall control. 1.3 - Project Summary 1.3.1 - Project Description The proposed project includes construction of 125 townhouse condominium units located in 19 three-story townhome condominium buildings. The buildings would be approximately 37 to 43 feet in height to the ridgeline, although the buildings with a rooftop deck may extend up to 45 feet in height. The 5.94-acre site would be developed with a total of approximately 237,816 square feet of new residential living area (293,139 total gross building square feet), resulting in a net density of 26.3 dwelling units per acre. As part of the proposed project, the existing eight parcels would be reconfigured into 19 new residential parcels (1–19), ranging in size from 7,706 square feet to 17,294 square feet, as well as 13 street and court lots (A–M), ranging in size from 2,808 and 9,834 square feet. The building site coverage area would be a maximum of 50 percent of the site (approximately 129,373 square feet). Thirteen of the 125 townhouse condominium units (10 percent) would comply with the Americans with Disabilities Act (ADA). Five unit types are proposed, ranging in size from 1,362 to 2,250 square feet with attached 1- or 2-car garages, 3 to 4 bedrooms, and 3 to 3.5 bathrooms. • Unit type 1A (27 units) would be 1,362 net square feet and 1,811 gross square feet. This unit type would include 3 bedrooms, 3 bathrooms, and a 449-square-foot tandem 2-car garage. • Unit type 1B (6 units) would be 1, 551 net square feet and 1,840 gross square feet. This unit type would include 4 bedrooms, 3 bathrooms, and a 289-square-foot single car garage. • Unit type 2 (20 units) would be 1,837 net square feet and 2,311 gross square feet. This unit type would include 3 bedrooms, 3.5 bathrooms, and a 474-square-foot standard 2-car garage. • Unit type 3 (34 units) would be 2,044 net square feet and 2,493 gross square feet. This unit type would include 4 bedrooms, 3.5 bathrooms, and a 449-square-foot standard 2-car garage. • Unit type 4 (38 units) would be 2,250 net square feet and 2,690 gross square feet. This unit type would include 4 bedrooms, 3.5 bathrooms, and a 440-square-foot standard 2-car garage. A total of 272 on-site parking spaces would be provided with available spaces along the street frontage. Primary vehicular access would be provided from main driveways on Jones and Oak Roads, which would also provide for emergency vehicle access.

Additional common features would include internal streets, courts, walkways, and drainage improvements. Off-site improvements would include installation of parking stalls along Oak Road and Jones Road. The proposed project would involve the demolition of all existing improvements currently present on-site, including buildings, foundations, asphalt, concrete, fence poles, and landscaping. In addition, 74 on-site trees would be removed, and one valley oak (Quercus lobata) would be relocated within the site. Six trees are located adjacent to the property boundaries and have canopies that extend onto the site. Although construction activities would occur within the drip lines of these trees, they would be afforded protection during construction to ensure their preservation. The trees would be pruned in accordance with arborist recommendations to reduce the size of tree crown over the project site. The project site is designated as Multiple-Family Residential–High Density (MH). As part of project approvals, the applicant is requesting rezoning of the site to Planned Unit District (P-1). Primary access to the site would be from two driveways: one along Jones Road and one along Oak Road. Off- site improvements would include frontage sidewalk, driveway curb, gutter improvements including retaining existing on-street parking, and street tree planting. A total of approximately 92,120 square feet of landscaped area (25 percent of the site) is proposed, including a central open space area, paseo/walkways, a dog park, and private yards. 1.3.2 - Project Objectives The objectives of the proposed project are to: • Develop an appropriate mix of multi-family units (including affordable units) that meets the existing General Plan land use designation and regional housing goals. • Provide affordable housing units in accordance with the Contra Costa County Housing Element (2014). • Locate housing in close proximity to transit in order to reduce vehicle miles traveled. • Provide housing with a variety of floor plans and unit types to enhance the economic viability of the development for long-term sustainability. • Retain the architectural and visual character of the neighborhood by building 3-story townhouse condominiums with roof-deck elements on selected homes fronting Oak Road and providing replacement landscaping that will mature over time. • Replace an obsolete private school with new market rate and affordable for-sale townhouse condominium homes consistent with the General Plan and surrounding neighborhood. • Establish physical and social connections between Jones and Oak Roads by building safe, private streets, walkable landscaped open spaces including stormwater management, and green building components. • Provide on-site open space amenities for future residents. • Phase development to allow for managed, orderly, and economically viable growth.

In lieu of a public gathering, the County Zoning Administrator was accessible live online and by telephone to all members of the public as permitted by the Governor’s Executive Order N29-20. During this time, the County Zoning Administrator was available to accept oral and written comments pertaining to environmental concerns related to the proposed project from interested agencies, organizations, and individuals. During this meeting, seven individuals presented verbal comments regarding the proposed project’s impacts on aesthetics, air quality and greenhouse gases, biological resources (specifically, the removal of trees), geology and soils, hazards and hazardous materials, land use and planning, noise, public services and recreation, and transportation and traffic. Additionally, public comments were submitted regarding proposed project’s building setbacks, height, design, foundations, and location, as well as potential effects on parking and neighborhood parks and trails, and construction impacts. These comments were addressed in the Draft EIR. The Draft EIR was circulated for a 45-day public review period between October 21, 2021, and December 6, 2021. During the public review period, the Draft EIR, including the technical appendices, was available for review at the Contra Costa County website (https://www.contracosta.ca.gov/8363/Oak-Road-Townhouse-Condominiums). Hard copies of the Draft EIR were available at the office of Contra Costa County Department of Conservation and Development and two alternative locations.

Contra Costa County prepared a Final EIR addressing the comment received during the 45-day public review and comment period on the Draft EIR and written responses to that comment. 1.4.2 - County’s Independent Review Contra Costa County independently reviewed and considered the entire administrative record before them, including but not limited to all oral and written comments regarding environmental issues in the Final EIR; written and oral testimony given at public meetings and hearings in connection therewith; the submission of comments from the public, organizations and regulatory agencies; and all other relevant information in the administrative record and determined, based on all of the evidence presented, that the following environmental impacts associated with the proposed project are: (1) less than significant and do not require mitigation; or (2) potentially significant but will be avoided or reduced to a level of insignificance through the identified mitigation measures. Contra Costa County concludes that implementation of the proposed project could result in potentially significant adverse environmental impacts unless mitigation is incorporated. Accordingly, as discussed above, Contra Costa County is required to make certain findings with respect to these impacts pursuant to CEQA Guidelines Section 15091, as set forth in this document (“Findings”). These Findings summarize the environmental determinations about the proposed project’s significant impacts before and after mitigation and summarize the proposed project’s individual and cumulative impacts. These Findings do not attempt to describe the full analysis of each environmental impact. Instead, they provide a summary description of each significant impact and the applicable mitigation measures identified in the Draft EIR and adopted by Contra Costa County and state the conclusions regarding the significance of each impact after incorporation of the identified mitigation measures. A comprehensive explanation of these environmental impact conclusions can be found in the Draft EIR, as supplemented and explained in staff reports and materials presented by the proposed project applicant, Contra Costa County staff, and various project consultants, and other relevant materials in the administrative record. The Draft EIR contains substantial evidence to support all the conclusions presented in these Findings. 1.4.3 - Incorporation of EIR For these Findings, the “EIR” shall consist of the Draft EIR, all appendices attached to the Draft EIR, and the Final EIR (consisting of the Introduction and Responses to Comments). Page references to the EIR will correspond to the page numbering in the publicly released Draft EIR, unless otherwise noted. The EIR is incorporated into these Findings in its entirety. Without limitation, this incorporation is intended to elaborate on the scope and nature of mitigation measures, the basis for determining the significance of impacts, the comparative analysis of alternatives, and the reasons for approving the proposed project. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 7 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx 1.5 - Potential Environmental Effects Which are Not Significant or Less than Significant Contra Costa County has heard, been presented with, reviewed, and considered all information and data in the administrative record, including the Draft and Final EIR, and all oral and written evidence presented to it during all meetings and hearings. The EIR reflects the independent judgment of the Contra Costa County and is deemed adequate for purposes of making decisions on the merits of the proposed project. Consistent with Public Resources Code Section 21002.1 and Section 15128 of the CEQA Guidelines, the EIR focused its analysis on potentially significant impacts. CEQA Guidelines Section 15091 does not require specific findings to address environmental effects that an EIR identifies as “no impact” or a “less than significant” impact and for which no mitigation is necessary. Nevertheless, Contra Costa County hereby finds that the proposed project would have either no impact or a less than significant impact as described below. Therefore, based on its independent judgment and the entire administrative record before it, Contra Costa County has determined that the project will have no impact on the following resources areas in their entirety: • Agriculture and Forestry Resources. No agricultural land or forestland currently exist on the project site. The site is mapped as “Urban and Built-Up Land” by the California Department of Conservation Farmland Mapping and Monitoring Program and is not under a Williamson Act Contract. In addition, the General Plan Conservation Element Figure 8-2 does not delineate the project site as an Important Agricultural Area. As such, construction and operation of the proposed project would not result in the conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide Importance to non-agricultural uses or result in the loss or conversion of forestland to non-forest uses. The proposed project would not conflict with any zoning for agricultural use or a Williamson Act Contract or any zoning for forestland or timberland. Therefore, Contra Costa County determines that substantial evidence supports a finding that no impacts related to agriculture or forestry resources would occur (Draft EIR, Chapter 6: Effects Found not to be Significant, Page 6-1). • Mineral Resources. There are no mineral resource recovery sites on or in the project vicinity. A Mineral Resource Zones and Resources Sectors map prepared by the California Geological Survey indicates that the project site is located in an area that does not contain any known mineral occurrences. There are no mines on the site or in the project vicinity. In addition, the General Plan Conservation Element Figure 8-4 indicates that no mineral resource zones are located on the project site or within the surrounding area. The site is designated as Multiple- Family Residential–High-Density (MH) by the General Plan; as such, construction and operation of the proposed project would not result in the loss of availability of a known mineral resource of value to the region and residents of the State. Therefore, Contra Costa County determines that substantial evidence supports a finding that no impacts related to mineral resources would occur (Draft EIR, Chapter 6: Effects Found not to be Significant, Page 6-2).

Therefore, based on its independent judgment and the entire administrative record before it, Contra Costa County has determined that the following potential environmental effects will not be significant and no mitigation is necessary for the reasons stated below. 1.5.1 - Aesthetics, Light, and Glare Potential Effect Impact AES-1 The proposed project would not have a substantial adverse effect on a scenic resource as identified in the General Plan (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-9). Findings Less than significant impact. Facts in Support of Findings There are no scenic resources, as defined by the General Plan, located on the project site. The nearest designated scenic resource to the project site is Diablo Ridge, located approximately 2.35 miles to the southeast, approximately 3.95 miles to the east, and approximately 7.45 miles to the northeast. The nearest scenic roads designated by the General Plan are Interstate 680 (I-680) and State Route (SR) 24, which intersect approximately 1.9 miles south of the site. Due to distance and intervening development, the project site is not visible from any scenic routes. During construction, removal of the buildings and vegetation would not adversely impact existing views within the project vicinity because the project site does not contain any designated scenic resources and is not visible from the nearest designated scenic routes, I-680 and SR-24. During operation, implementation of the proposed project would not result in a substantial adverse effect on a scenic vista because there are no scenic ridges, hillsides, or rock outcroppings on the project site, nor are any scenic resources visible from the project site nor would development of the project site interfere with views of any scenic resources (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-9). Potential Effect Impact AES-2 The proposed project would not substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic building within a State Scenic Highway (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-10). Findings Less than significant impact. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 9 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Facts in Support of Findings The nearest officially Designated State Scenic Highways are I-680 and SR-24 at their intersection, located approximately 1.9 miles south of the project site; because of the distance to these resources and intervening development, the project site is not visible from either route. In addition, there are no scenic resources, as designated by the General Plan located on the project site. Given the absence of scenic highways proximate to the project site, the lack of designated scenic resources (i.e., ridgelines, hillsides, rock outcroppings) on the project site, and the presence of intervening development between the project site and the nearest scenic highways, the proposed project would not adversely affect views from a State Scenic Highway (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-10). Potential Effect Impact AES-3 The proposed project is in an urbanized area and would not conflict with applicable zoning and other regulations governing scenic quality (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-10–11). Findings Less than significant impact. Facts in Support of Findings Considering the residential character of the project site surroundings, construction activities could temporarily affect existing visual character or quality of the project site and area. However, the area surrounding the project site has a transit-oriented residential character with multi-family apartments located to the north and to the south. The construction of the proposed project would temporarily affect visual character and quality of the area. However, construction-related impacts related to degradation of existing visual character or quality of the project site and area would be nominal, temporary, and less than significant. The proposed project would change the visual character of the site. However, the proposed project would be consistent with the character of the surrounding area, as the area continues to transition toward higher density multi-family residential uses. The General Plan designates the site as Multiple- Family Residential–High Density (MH). As part of project implementation, the zoning of the project site would be changed to Planned Unit District (P-1). The P-1 Zoning District is intended to support large-scale integrated development in compliance with the General Plan designations. The proposed project would be consistent with the Design Objectives identified in Section 84-66.1402 of the Ordinance Code related to the P-1 Zoning District. For example, the buildings bulk, height, land coverage, and visual appearance is compatible with existing adjoining development. In addition, the design of the buildings provides for harmonious composition of mass, scale, color, and textures. The proposed project also includes implementation of a landscaping plan, including approximately 250 trees and hundreds of shrubs, vines, and groundcover. The establishment of trees and other plantings would support the transition of the site to reflect the residential character of surrounding properties (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-10–11).

Findings Less than significant impact. Facts in Support of Findings Cumulative projects are identified in Table 3-1 of the Draft EIR. The degree to which past projects are included within the list of projects is generally limited, due to the fact that past projects are included in the current environmental conditions already considered as part of the baseline and existing environmental setting. None of the Cumulative Projects would be located within the same visible area as the proposed project. The proposed project and Cumulative Projects 1 and 2, as provided in Table 3-1 of the Draft EIR, would be subject to the same County codes and guidelines related to lighting, building heights, setbacks, undergrounding of utilities, landscaping, signage, and permitted land uses. Cumulative Projects 3–13 in the Draft EIR would be subject to the codes and guidelines associated with the City of Walnut Creek related to lighting, building heights, setbacks, undergrounding of utilities, landscaping, signage, and permitted land uses. Cumulative Projects 14– 24 in the Draft EIR would be subject to the codes and guidelines associated with the City of Pleasant Hill related to building heights, setbacks, undergrounding of lighting, utilities, landscaping, signage, and permitted land uses. As such, the proposed project, in conjunction with other planned and approved projects, would result in a less than significant cumulative impact with respect to visual character, views, lighting and glare. 1.5.2 - Air Quality Potential Effect Impact AIR-1 The proposed project would not conflict with or obstruct implementation of the applicable air quality plan (Draft EIR, Section 3.2, Air Quality, Page 3.2-37). Findings Less than significant impact. Facts in Support of Findings The Bay Area Air Quality Management District (BAAQMD) is responsible for reducing emissions from area, stationary, and mobile sources in the Air Basin to achieve National Ambient Air Quality Standards (NAAQS) and California Ambient Air Quality Standards (CAAQS). The BAAQMD 2017 Clean Air Plan is a regional and multiagency effort to reduce air pollution in the Air Basin. A project would be judged to conflict with or obstruct the 2017 Clean Air Plan implementation if it would result in substantial new regional emissions not foreseen in the air quality planning process. The BAAQMD does not provide a numerical threshold of significance for project-level consistency analysis with Air Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 11 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Quality Plans (AQPs). Therefore, the following criteria was used for determining the project’s consistency with the AQP. • Criterion 1: Does the project support the primary goals of the AQP? • Criterion 2: Does the project include applicable control measures from the AQP? • Criterion 3: Does the project disrupt or hinder implementation of any AQP control measures? Criterion 1: The proposed project’s density and use would be consistent with the General Plan land use designation and the proposed project would not require a General Plan Amendment. The proposed project would not introduce a greater amount of population growth than what was envisioned by the General Plan and, subsequently, the AQP. Therefore, the anticipated population growth facilitated by the proposed project was anticipated in the 2017 Clean Air Plan and the project would not conflict with the goals contained in the AQP. The proposed project is consistent under Criterion 1. Criterion 2: As shown in the Consistency Analysis on Page 3.2-39 to Page 3.2-42 of the Draft EIR, the proposed project would be consistent with applicable measures in the 2017 Clean Air Plan and would not conflict with or hinder BAAQMD from implementing the control measures in the 2017 Clean Air Plan. The proposed project is consistent under Criterion 2. Criterion 3: The proposed project would not preclude extension of a transit line or bike path, propose excessive parking beyond parking requirements, or otherwise create an impediment or disruption to implementing any AQP control measures. The proposed project would incorporate several AQP control measures as project design features. Considering this information, the proposed project would not disrupt or hinder the implementation of any AQP control measures. Therefore, the proposed project would be consistent under Criterion 3. The proposed project would be consistent with all three criteria after the incorporation of identified mitigation, and therefore, the proposed project ’s related impacts would be less than significant (Draft EIR, Section 3.2, Air Quality, Pages 3.2-37–43). Potential Effect Impact AIR-4 The proposed project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people (Draft EIR, Section 3.2, Air Quality, Page 3.2-53). Findings Less than significant impact. Facts in Support of Findings During construction activities, construction equipment exhaust and application of asphalt and architectural coatings would temporarily generate odors. Any construction-related odor emissions would be temporary and intermittent. Additionally, noxious odors would be confined to the immediate vicinity of the construction equipment. It is anticipated that by the time such emissions Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 12 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx reach any sensitive receptor sites, they would be diluted to well below any level of air quality or odor concern; therefore, impacts would be less than significant. Operation of the proposed project would likely not generate objectionable odors. The type of uses that are considered to have objectionable odors include wastewater treatments plants, compost facilities, landfills, solid waste transfer stations, fiberglass manufacturing facilities, paint/coating operations (e.g., auto body shops), dairy farms, petroleum refineries, asphalt batch plants, chemical manufacturing, and food manufacturing facilities. As the proposed project is residential in nature, it is not anticipated to generate objectionable odors which may affect a substantial number of people (Draft EIR, Section 3.2, Air Quality, Page 3.2-53). 1.5.3 - Biological Resources Potential Effect Impact BIO-2 The proposed project would not have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service (Draft EIR, Section 3.3, Biological Resources, Page 3.3-21). Findings No impact. Facts in Support of Findings The project site is developed and is almost entirely covered with impervious surfaces due to existing development to the extent that no natural habitat remains present on-site. The trees that are present are located in pockets surrounded by hardscaped areas. Historical aerial photographs indicate that most of the oak trees on-site appear to be ornamental plantings; thus, they are not part of a natural community (e.g., naturally occurring oak savanna or oak woodland). The project site does not contain riparian habitat or other sensitive natural communities identified in local or regional plans, policies, and regulations or by the California Department of Fish and Wildlife (CDFW) or United States Fish and Wildlife Service (USFWS) (Draft EIR, Section 3.3, Biological Resources, Page 3.3-21). Therefore, the proposed project would have no impact on an identified riparian habitat or sensitive natural community. Potential Effect Impact BIO-3 The proposed project would not have a substantial adverse effect on State or federally protected wetlands (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means (Draft EIR, Section 3.3, Biological Resources, Page 3.3-22). Findings No impact. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 13 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Facts in Support of Findings The project site is developed and does not contain jurisdictional drainages, wetlands, or hydrophytic vegetation or soils. On-site stormwater runoff sheet flows across the project site and is captured by drainage inlets connected by municipal underground storm drain pipes that discharge into existing storm drainage infrastructure. As such, the proposed project would not directly or indirectly remove, fill, or hydrologically interrupt State or federally protected wetlands (Draft EIR, Section 3.3, Biological Resources, Page 3.3-22). For these reasons, the proposed project would have no impact on protected wetlands. Potential Effect Impact BIO-4 The proposed project would not interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of wildlife nursery sites (Draft EIR, Section 3.3, Biological Resources, Page 3.3-22). Findings Less than significant impact. Facts in Support of Findings The project site is in a built out urban area and does not contain any habitat features such as riparian corridors or waterways that could function as wildlife corridors. Moreover, there are multiple barriers to wildlife migration including I-680 and multiple residential and commercial developments, which further precludes wildlife movement (Draft EIR, Section 3.3, Biological Resources, Pages 3.3- 22–23). Therefore, the proposed project does not have the potential to substantially reduce the habitat of any species or interfere with movement and impacts are less than significant. Potential Effect Impact BIO-6 The proposed project would not conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or State Habitat Conservation Plan (Draft EIR, Section 3.3, Biological Resources, Page 3.3-24). Findings No impact. Facts in Support of Findings The project site does not fall within the coverage area of a Habitat Conservation Plan (HCP) or Natural Community Plan (NCCP). The project site is roughly 5 miles west of the East Contra Costa County HCP area, the nearest Habitat Conservation Plan area (Draft EIR, Section 3.3, Biological Resources, Page 3.3-24). Accordingly, no impacts would occur. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 14 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Potential Effect Cumulative Impact Implementation of the project, in conjunction with other planned and approved projects, would result in less than significant cumulative impacts to biological resources (Draft EIR, Section 3.3, Biological Resources, Page 3.3-26). Findings Less than significant impact. Facts in Support of Findings Special-status Species While there are a limited number of isolated pockets of natural habitat that can support special- status wildlife and plant species, the built-up nature of the cumulative project areas precludes the possible cumulative impacts to biological resources related to special-status wildlife and plant species. However, the varying degree of trees present in and around the urban areas may provide suitable nesting habitat for birds protected by the Migratory Bird Treaty Act (MBTA ). Standard pre- construction surveys and, if necessary based on the survey results, avoidance procedures would be required for cumulative projects with the potential to impact nesting birds and protected bat species (Draft EIR, Section 3.3, Biological Resources, Page 3.3-25). For these reasons, cumulative impacts are less than significant. Additionally, as discussed above, the project’s contribution to the less than significant cumulative impacts is not cumulatively considerable. Sensitive Natural Communities or Riparian Habitat Within the County, the City of Pleasant Hill, and the City of Walnut Creek, there are several small waterbodies, including the Walnut Creek waterway, Grayson Creek, and associated riparian habitats. These areas are considered sensitive natural communities. The majority of current developments are designed to address future growth problems, prevent urban sprawl, and minimize developmental impacts to sensitive natural communities. This is accomplished by designing projects to occur in previously developed or highly disturbed areas that the characteristics of lack sensitive natural communities or riparian habitat. As such, the project, in conjunction with other cumulative projects, would result in a less than significant cumulative impact related to sensitive natural communities and associated riparian habitat (Draft EIR, Section 3.3, Biological Resources, Page 3.3-25). Waters of the United States and Waters of the State The County, the City of Pleasant Hill, and the City of Walnut Creek contain several areas that would be considered jurisdictional features. As such, current projects are occurring in a highly developed and disturbed area with low potential for jurisdictional features to be impacted by project development. If any issues were to arise due to current development, the applicant would be required to obtain appropriate permits from the United States Army Corp of Engineers (USACE), Regional Water Quality Control Board (RWQCB), and CDFW and to compensate for loss of waters of the United States/State through re-creation or payment of mitigation credits and re-creation of lost habitat. Due to the limited scope of current projects, which are occurring in highly developed and disturbed areas, it is expected there will be a less than significant cumulative impact related to waters of the United States/State (Draft EIR, Section 3.3, Biological Resources, Page 3.3-25). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 15 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Local Policies or Ordinances Many of the current development projects are occurring in previously developed or disturbed areas. As such, a limited number of trees within the geographical scope are likely to occur. Current project developments may require an Arborist report to determine the identity of trees planned for removal or encroachment. Therefore, the project, in conjunction with other future development projects, would be required to adhere to applicable tree ordinances and regulations set by the County and the City of Walnut Creek and City of Pleasant Hill resulting in a less than significant cumulative impact to biological resources related to local policies and ordinances (Draft EIR, Section 3.3, Biological Resources, Pages 3.3-25–26). Fish and Wildlife Movement Corridors The main wildlife corridor in the vicinity of the project site is the Walnut Creek waterway, which generally borders the I-680 corridor, stretching from northern San Ramon to Suisun Bay. There are several small water channels and tributaries that are located within the geographical scope of this project. The project site is located to the west of the waterway and due to the size and location of the proposed project it will not result in any potential impacts to wildlife corridors. Any current development that occurs within the geographic scope of the County, the City of Walnut Creek and the City of Pleasant Hill will have to take into account the potential impact to these corridors. The areas surrounding the potential corridors within the previously mentioned geographical scope are highly developed, further impeding the movement of species out from these areas. As such, there will be a less then significant cumulative impact to biological resources related to movement corridors for fish and wildlife (Draft EIR, Section 3.3, Biological Resources, Page 3.3-26). Additionally, because the proposed project site does not contain any habitat or movement corridors, the project’s contribution to the less than significant cumulative impacts is not cumulatively considerable. Habitat and Natural Community Conservation Plan Consistency The project site is not located within the East Contra Costa County HCP. The HCP provides for comprehensive species, wetlands, and ecosystem conservation, and contributes to the recovery of endangered species in Eastern Contra Costa County. Any current project sites within the boundaries of the HCP will have to adhere to the additional regulations and guidelines established by the HCP. This may include additional surveys for listed species, developments fees, and various other directives. As such, there will be a less then significant cumulative impact to biological resources relating to developments occurring in Habitat Community Conservation Plans. Additionally, because the proposed project is not located within an HCP or NCCP, the proposed project’s contribution to the less than significant cumulative impacts is not cumulatively considerable (Draft EIR, Section 3.3, Biological Resources, Page 3.3-26).

Findings Less than significant impact. Facts in Support of Findings Construction of the proposed project was assumed to begin in September 2022 and continue through November 2023. If the construction schedule moves to later years, construction energy demand would likely decrease because of improvements in technology and more stringent regulatory requirements. Project construction would require energy for the manufacture and transportation of building materials, preparation of the site (e.g., demolition, site clearing, and grading), and the actual construction of the buildings. Petroleum-based fuels such as diesel fuel and gasoline would be the primary sources of energy for these tasks. Much of the energy consumption is likely to occur in the first year when demolition, site preparation, and grading activities occur. The types of on-site equipment used during construction of the proposed project could include gasoline- and diesel-powered construction and transportation equipment, including trucks, bulldozers, frontend loaders, forklifts, and cranes. Construction equipment is estimated to consume a total of 36,941 gallons of diesel fuel over the entire construction duration (Draft EIR, Section 3.5, Energy, Page 3.5-11). Fuel use associated with construction vehicle trips generated by the proposed project was also estimated. In total, the proposed project is estimated to generate 498,347 Vehicle Miles Traveled (VMT) and a combined 23,042 gallons of gasoline and diesel for vehicle travel during construction (Draft EIR, Section 3.5, Energy, Page 3.5-12). Other equipment could include construction lighting, field services (office trailers), and electrically driven equipment such as pumps and other tools. Singlewide mobile office trailers, which are commonly used in construction staging areas, generally range in size from 160 square feet to 720 square feet. A typical 720-square-foot office trailer would consume approximately 15,722 kilowatt hours (kWh) during the 1.2-year construction phase. This energy use is typical and consistent with other similar energy efficient projects. Additionally, the proposed project’s construction is not anticipated to result in unusually high energy use. Limitations on idling of vehicles and equipment and requirements that equipment be properly maintained would minimize the use of fuel. Similarly, compliance with State regulations would limit idling from both on-road and off-road diesel-powered equipment and are enforced by the California Air Resources Board (ARB). Additionally, the overall construction schedule and process is already designed to be efficient in order to avoid excess monetary costs. For example, equipment and fuel Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 17 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx are not typically used wastefully due to the added expense associated with renting the equipment, maintaining it, and fueling it. Therefore, the opportunities for future efficiency gains during construction are limited (Draft EIR, Section 3.5, Energy, Page 3.5-12). The proposed project would consume energy as part of building operations and transportation activities. Unmitigated operation of the proposed project would consume an estimated 635,439 kWh of electricity and an estimated 0 kilo-British thermal unit (kBTU) of natural gas on an annual basis. The proposed project’s buildings would be designed and constructed in accordance with the County’s latest adopted energy efficiency standards, which are based on the State’s Building Energy Efficiency Standards. These are widely regarded as the most advanced building energy efficiency standards, and compliance would ensure that building energy consumption would not be wasteful, inefficient, or unnecessary. The proposed project is designed be all electric construction in the new homes with no natural gas provided. Each home will also have rooftop solar panels (Draft EIR, Section 3.5, Energy, Page 3.5-13). In total, the proposed project would consume 63,021 gallons of gasoline and diesel per year starting in 2023. The majority of operational fuel consumption would be from employee vehicle emissions, which would be regulated by State and federal policies and could not be feasibly mitigated by the proposed project or County. The site is served by several County Connection bus routes: 7, 9, 11, 14, 15, and 311. The closest bus stop to the project site is located at Oak Road and Walden Park, approximately 970 feet south of the project site. There are sidewalks on Oak Road that provide connectivity to the bus stop. There are no existing bike lanes on Jones Road. The Iron Horse Regional Trail, located approximately 1,500 feet east of the project site, provides a multiuse bicycle/pedestrian pathway, which access to the Pleasant Hill Bay Area Rapid Transit (BART) station. There is also another bicycle/pedestrian trail, Contra Costa Canal Trail, located approximately 450-600 feet south of the project site, which crosses Oak Road and Jones Road. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. The proposed project would not affect existing and planned bicycle facilities. The project also proposes to include a bike repair space on-site. As a result, the proposed project is located near regional and local roadway. Transportation fuel consumption would not be wasteful, inefficient, or unnecessary (Draft EIR, Section 3.5, Energy, Page 3.5-13). For these reasons, impacts would be less than significant. Potential Effect Impact ENER-2 The proposed project would not conflict with or obstruct a State or local plan for renewable energy or energy efficiency (Draft EIR, Section 3.5, Energy, Page 3.5-13). Findings Less than significant impact. Facts in Support of Findings The proposed project would be designed in accordance with Title 24, California’s Energy Efficiency Standards for Residential Buildings. These standards include minimum energy efficiency Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 18 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx requirements related to building envelope, mechanical systems (e.g., heating, ventilation, and air conditioning [HVAC] and water heating systems), and indoor and outdoor lighting. Furthermore, the proposed rooftop solar panels would supply, at least in part, the additional electricity demand for appliances. The incorporation of the Title 24 standards into the design of the proposed project would ensure that the proposed project would not result in the use of energy in a wasteful manner. Furthermore, the proposed rooftop solar panels would supply the increased electricity demand. (Draft EIR, Section 3.5, Energy, Page 3.5-14). Compliance with Title 24 standards would ensure that the proposed project would not conflict with any of the Conservation Element energy conservation policies related to the proposed project’s building envelope, mechanical systems, and indoor and outdoor lighting. Moreover, the proposed project would be consistent with the greenhouse gas (GHG) emissions reduction measures contained in the County’s Climate Action Plan (CAP), which are closely related to and include energy efficiency measures. The proposed project would comply with existing State energy standards and be consistent with the energy efficiency goals and measures contained in the County’s General Plan Conservation Element and CAP. As such, the proposed project would not conflict with State or local renewable or energy efficiency objectives (Draft EIR, Section 3.5, Energy, Page 3.5-14) and impacts would be less than significant Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in a less than significant cumulative impact with respect to the wasteful or inefficient use of energy. (Draft EIR, Section 3.5, Energy, Page 3.5-15). Findings Less than significant impact. Facts in Support of Findings The geographic scope of the cumulative energy analysis is the portion of Pacific Gas and Electric Company (PG&E’s) service area that covers incorporated and unincorporated County. Cumulative projects would be required to comply with Title 24 Building Energy Efficiency Standards and the California Green Building Standards Code (CALGreen). The cumulative buildings would be designed in accordance with Title 24, California’s Energy Efficiency Standards for Residential Buildings as applicable. These standards include minimum energy efficiency requirements related to building envelope, mechanical systems (e.g., HVAC and water heating systems), and indoor and outdoor lighting. Future development would also be required to meet even more stringent energy efficiency requirements through local and Statewide policy, such as Title 24, Part 6, which would require that newly constructed residential homes include on-site photovoltaic solar systems, with some exceptions. Furthermore, PG&E, which supplies electricity to the project area, would be required by Senate Bill (SB) 100 to incrementally increase the proportion of renewable electricity generation supplying its in-state retail sales until it reaches 100 percent carbon-free electricity generation by 2045 (Draft EIR, Section 3.5, Energy, Page 3.5-14).

Cumulative projects would be required to comply with California Code of Regulations Title 13, Sections 2449(d)(3) and 2485, that limit idling from both on-road and off-road diesel-powered equipment and are enforced by the ARB. Additionally, various federal and State regulations, including the low carbon fuel standard (LCFS), Pavley Clean Car Standards, and Low Emission Vehicle (LEV) Program, would serve to reduce the transportation fuel demand of cumulative projects. Compliance with these regulations by the cumulative projects would ensure that the cumulative projects would not result in the inefficient, unnecessary, or wasteful consumption of fuel and the cumulative impact would be less than significant (Draft EIR, Section 3.5, Energy, Page 3.5-15). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project would not have a significant incremental contribution to cumulative impacts. The proposed project’s energy use would be limited to that which is necessary for the construction and operation of the proposed project. The proposed project would comply with Statewide and local policies pertaining to energy efficiency and would reasonably pursue greater energy efficiencies in its operation in the interest of reducing operating costs. Consistency with the local, State, and federal regulations cited above would be required during the design review process to ensure that projects comply with all applicable policies, including requirements in the California Energy Code. Therefore, the proposed project’s contribution to cumulative impacts would be considered less than significant. 1.5.5 - Geology and Soils Potential Effect Impact GEO-5 The proposed project would not have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-19). Findings No impact. Facts in Support of Findings Impacts related to soil capability of supporting the use of alternative wastewater disposal systems are limited to operational impacts; therefore, there are no construction impacts. The proposed project does not include the use of septic tanks or alternative wastewater disposal systems. The proposed project is located within an urbanized portion of the County and would include wastewater infrastructure and connections to the existing sanitary sewer lines contained with Oak Road (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-19). Accordingly, there is no impact.

Findings Less than significant impact. Facts in Support of Findings The geographic scope of the cumulative analysis related to geology and soils is the project site and its vicinity. Adverse effects associated with geology and soils tend to be localized; therefore, an area generally within a 0.25-mile radius would be the area most affected by activities associated with the proposed project. Seismic-related Hazards None of the cumulative projects are located within 0.25 mile of the project site. Cumulative projects, including the proposed project, have the potential to experience moderate to strong ground shaking from earthquakes. Cumulative projects would be exposed to the same ground shaking hazards and would be subject to the same requirements as the proposed project. Cumulative projects would adhere to the provisions of the California Building Standards Code (CBC), policies of the General Plan, and the Municipal Code or Ordinance Code to reduce potential hazards associated with seismic ground shaking and ground failure (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-21). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project would not have a significant incremental contribution to cumulative impacts because adverse effects associated with seismic hazards tend to be localized and there are no cumulative projects within 0.25 mile of the project site. Soil-related Hazards Soil conditions associated with the project site, such as expansive soils, corrosive soils, and soil settlement, are specific to the project site and generally do not contribute to a cumulative effect. Some or all other cumulative projects may have similar conditions, but they would not contribute to cumulative soil-related hazards. Other current and future development/redevelopment projects in the region would similarly be required to adhere to standards and practices that include stringent geologic and soil-related hazard mitigations (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-21). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project would not have a significant incremental contribution to cumulative impacts because the proposed project would be subject to General Plan policies and the Ordinance Code be required during the design review process to ensure that projects comply with all applicable policies to reduce soil-related hazards. Paleontological Resources and Unique Geologic Feature None of the cumulative projects would occur within 0.25 mile of the project site. Construction activities associated with development of cumulative projects in the project vicinity may have the Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 21 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx potential to encounter undiscovered geologic resources or paleontological resources. These cumulative projects would be required to mitigate for impacts through compliance with applicable federal and State laws governing geologic resources and paleontological resources. The likelihood that geologic resources or paleontological resources are present on the cumulative project sites is relatively low, given that the majority of soil disturbance associated with these projects will take place within Holocene soils too young to be fossiliferous. Although there is the possibility that previously undiscovered resources could be encountered by subsurface earthwork activities, the implementation of standard construction practices and Mitigation Measure (MM) GEO-6, which requires the cessation of construction activities in the event of an unanticipated discovery, would ensure that undiscovered geologic resources and paleontological resources are not adversely affected by cumulative project-related construction activities. Accordingly, potential cumulative impacts would be less than significant, and no mitigation is necessary. Moreover, the proposed project would not have a significant incremental contribution to cumulative impacts because adverse geological or soils effects tend to be localized or specific to the project site, and there are no cumulative projects located within 0.25 mile of the project site. Given the low potential for disruption and the comprehensiveness of mitigation measures that would apply to the cumulative projects, the project, in conjunction with other planned and approved projects, would result in a less than significant cumulative impact related to paleontological and geologic resources (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-21). 1.5.6 - Greenhouse Gas Emissions Potential Effect Impact GHG-1 The proposed project would not generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment (Draft EIR, Section 3.7, Greenhouse Gas Emissions, Page 3.7-41). Findings Less than significant impact. Facts in Support of Findings GHG emissions associated with development of the proposed project would occur over the short term from construction activities, consisting primarily of emissions from equipment exhaust and worker and vendor trips. There would also be long-term operational emissions associated with vehicular traffic within the project vicinity, energy and water usage, and solid waste disposal (Draft EIR, Section 3.7, Greenhouse Gas Emissions, Page 3.7-41). GHG emissions associated with construction were estimated to be 368 metric tons (MT) of carbon dioxide equivalent (CO2e) for the total construction period. These would represent the GHG emissions generated from on-site operation of construction equipment, vendor and hauling truck trips, and worker trips. The proposed project would contribute to global climate change through direct and indirect emissions of GHG from transportation sources (passenger vehicles, trucks), energy (natural gas and purchased energy), water use and wastewater generation, and solid waste generation. According to Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 22 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx the California Emissions Estimator Model (CalEEMod), the proposed project is estimated to consume approximately 635,440 kWh per year, and according to the solar system capacity calculations, the proposed project would generate an estimated 301,400 kWh per year. Therefore, the electricity related GHG emissions estimated for project operation were reduced to reflect the GHG emissions generated from the electricity consumed that would not be covered by the rooftop solar system. As shown in Table 3.7-5, the annual GHG emissions resulting from operation of the proposed project are estimated to be 677 MT of CO2e in 2024 and would exceed the 660 MT CO2e/year bright-line threshold (Draft EIR, Table 3.7-5: Annual Project GHG Emissions, Page 3.7-43). While the proposed project would involve demolition of the existing Palmer School and it is normal practice to include existing emission estimates to demonstrate net GHG emissions resulting from the proposed project, the Palmer School was not in operation at the time the NOP was issued for this project. Nonetheless, because the school could become operational in the future, operational GHG emission estimates for operation of Palmer School are provided in Table 3.7-6 of the Draft EIR for informational purposes (Page 3.7-44). The proposed project was analyzed against the efficiency threshold which was calculated to demonstrate consistency with the 40 percent below 1990 emission levels reduction target of SB 32. The proposed project would not exceed the efficiency threshold and would be consistent with the GHG emission reductions required under SB 32 (Draft EIR, Table 3.7-5: Annual Project GHG Emissions, Page 3.7-44). Accordingly, the proposed project would not have a significant effect with respect to greenhouse gas emissions. Potential Effect Impact GHG-2 The proposed project would not conflict with any applicable plan, policy or regulation of an agency adopted for the purpose of reducing the emissions of greenhouse gases (Draft EIR, Table 3.7-5: Annual Project GHG Emissions, Page 3.7- 44). Findings Less than significant impact. Facts in Support of Findings The EIR discusses project consistency with applicable plans adopted for the purpose of reducing GHG emissions, which include ARB’s Scoping Plan and the Contra Costa County CAP. The proposed project incorporates several design elements that would reduce GHG emissions, such as conformance to the 2019 Building Energy Efficiency Standards and CALGreen building regulations and installation of a photovoltaics (PV) system. In addition, a development checklist under the County’s CAP was filled out for the proposed project to demonstrate compliance. The proposed project would also be consistent with the measures in the County CAP (Draft EIR, Table 3.7-7: Contra Costa County Climate Action Plan Consistency, Page 3.7-45).

Findings Less than significant impact. Facts in Support of Findings GHG emissions and global climate change inherently represent cumulative impacts. GHG emissions cumulatively contribute to the significant adverse environmental impacts of global climate change. No single project could generate enough GHG emissions to noticeably change the global average temperature; instead, the GHG emissions from past, present, and future projects and activities have contributed to and would contribute to global climate change and its associated environmental impacts. According to the BAAQMD, project GHG emissions are inherently cumulative and do not require the estimation of cumulative projects in the region of the project. Thus, the determination of GHG cumulative impacts is based on the State target established by Assembly Bill (AB) 32 to reduce GHG emissions to 1990 levels by 2020. In order to ensure that this goal would be achieved, Air Districts and Lead Agencies developed GHG thresholds to ensure compliance with the State target. Projects with GHG emissions in conformance with these thresholds, therefore, would not be considered significant for purposes of CEQA. As analyzed in Impact GHG-1, the proposed project would have a GHG emissions benefit when compared to the emissions generated by existing land uses, or the environmental baseline, and would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing GHG emissions. Although the emissions from cumulative projects would add an incremental amount to the overall GHG emissions that cause global climate change impacts, because emissions from the proposed project are below the applicable GHG significance thresholds, the proposed project would not present a “cumulatively considerable” contribution to GHG emission impacts under CEQA (Draft EIR, Section 3.7, Greenhouse Gas Emissions, Page 3.7-47). Accordingly, the proposed project’s contribution to cumulative greenhouse gas emissions is less than significant. 1.5.7 - Hazards and Hazardous Materials Potential Effect Impact HAZ-2 The proposed project would not create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials into the environment (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-22). Findings Less than significant impact.

The use of these materials would be subject to the Hazardous Materials Tran sportation Act, California Public Resources Code, and other State and local regulations that would limit the use of hazardous materials and reduce the associated risks of exposure. Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations, including the United States Environmental Protection Agency (EPA ), Resource Conservation and Recovery Act (RCRA), California Department of Transportation (Caltrans), the Hazardous Materials Transportation Act, and the Contra Costa County Hazard Mitigation Plan (HMP) (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-22). The proposed project is residential and does not include industrial or retail development that involves hazardous materials such as gas stations, paint stores, or auto parts stores. Unlike industrial or retail facilities, residential development does not involve the type or quantity of hazardous materials that could pose a significant environmental accident. Small quantities of hazardous materials would be used on-site during operation of the project but not in sufficient quantities to create a significant hazard. These types of materials are common in residential projects and represent a low risk to people and the environment when used as intended and would not be expected to result in the release of hazardous materials into the environment. (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-23). Accordingly, impacts are less than significant. Potential Effect Impact HAZ-3 The proposed project would not emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-23). Findings Less than significant impact. Facts in Support of Findings The project site, including the areas proposed for off-site improvements, are not located within 0.25 mile of an existing or proposed school. The closest school, Fusion Academy (a private school), is located approximately 0.33 mile to the north. Construction activity would be expected to involve the transport, use, and disposal of hazardous materials, such as diesel fuels, aerosols, and paints. The handling, transport, use, and disposal of hazardous materials must comply with the Hazardous Materials Transportation Act, California Public Resources Code, and other State and local regulations, which further limits the risk of emissions. The proposed project does not include industrial or retail development that involves hazardous materials such as gas stations, paint stores, or auto parts stores. Unlike industrial or retail facilities, residential development does not involve the type or quantity of hazardous materials that could pose a significant environmental accident (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-23). As such, the proposed project would not Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 25 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx emit hazardous emissions or handle hazardous materials within 0.25 mile of a school and impacts would be less than significant. Potential Effect Impact HAZ-5 The proposed project would not be located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, and result in a safety hazard or excessive noise for people residing or working the project area (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-24). Findings No impact. Facts in Support of Findings The proposed project would not be located within an airport land use plan or within 2 miles of a public airport. The closest public airport, Buchanan Field, is located approximately 4.4 miles to the north of the project site (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-25). Potential Effect Impact HAZ-6 The proposed project would not impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-25). Findings Less than significant impact. Facts in Support of Findings The proposed project would comply with the Contra Costa County Emergency Plan, ensuring efficient response to emergency incidents associated with emergencies affecting Contra Costa County during construction. Additionally, during operation, the proposed project would adhere to the procedures of the Contra Costa County Operational Area Emergency Operations Plan (EOP). The population growth anticipated with the proposed project would be within the General Plan’s 2020 population and dwelling projections for the unincorporated area and, therefore, would not be considered substantial. Furthermore, it would also be within the Association of Bay Area Government (ABAG’s ) 2020-2040 regional population growth projections. Therefore, the proposed project would not create a permanent increase in population unaccounted for in the General Plan that could lead to overwhelming call for police and fire services. In addition, the project site would be designed in accordance with the County’s standards to accommodate emergency vehicle access by providing two points of access that would be available to emergency vehicles (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-25). Impacts would be less than significant. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 26 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Potential Effect Impact HAZ-7 The proposed project would not expose people or structures, either directly or indirectly to a significant risk of loss, injury or death involving wildland fires (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-26). Findings Less than significant impact. Facts in Support of Findings Fire hazards present a considerable problem throughout the County, primarily within undeveloped areas with natural vegetation and steep slopes. The project site is surrounded by urbanized uses on areas relatively flat in elevation, lacking in woodlands or vegetation that could provide fuel load for wildfire or steep slopes that could cause fire to spread more rapidly. The project site is surrounded by other features that provide fuel breaks in the event of a fire, such as Oak Road and Jones Road. In addition, the Contra Costa Canal is approximately 450 to 650 feet south of the project site. According to the California Department of Forestry and Fire Protection (CAL FIRE), the project site is not located in a Moderate, High, or Very High Fire Hazard State Responsibility Area. Two miles west of the project site, Briones Regional Park is designated as a High Fire Hazard Severity Zone. Given that the project site is not located on or near steep terrain surrounded by natural vegetation, is surrounded by urban uses, and does not consistently experience high winds, the project site would not be prone to wildfires. Compliance with applicable State and local plans and regulations would decrease the risk of impacts related to wildland fire hazards. Specifically, the General Plan policies incorporate requirements for fire-safe construction into the land use planning and approval process and ensure special fire protection for high-risk land uses and structures. Contra Costa County also implements the Contra Costa County Operational Area EOP, which addresses the response to emergency incidents associated with emergencies affecting Contra Costa County. Furthermore, the proposed project would be adequately served in terms of fire protection services by the Contra Costa County Fire Protection District (CCCFPD). Finally, proposed structures would be required to comply with the California Fire Code with regard to emergency access and types of building materials (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Pages 3.8-25–26). For these reasons, impacts would be less than significant. Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in a less than significant cumulative impact associated with hazards and emergency response (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-28). Findings Less than significant impact. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 27 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Facts in Support of Findings The geographic scope of the cumulative analysis related to hazards and hazardous materials is the project vicinity or roughly the western portion of the County. Cumulative development projects primarily consist of residential and commercial development. The types and sizes of development anticipated in the project area would not involve large quantities of hazardous materials or activities that transport or handle hazardous materials. Cumulative projects would be subject to the Hazardous Materials Transportation Act, California Public Resources Code, and other State and local regulations that would reduce and limit the associated risks. Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations, including the EPA, RCRA, Caltrans, and the HMP. However, cumulative projects may include demolition of existing structures that have the potential to contain hazardous building materials. Building materials may contain asbestos-containing material (ACM) and lead-based paint (LBP). To address potential release of hazardous materials, the County would assess structures and impose standard mitigation (required testing, removal, and proper disposal) to minimize release prior to any demolition. Additionally, regional, State, and federal regulations would apply to countywide development, and, for these reasons cumulative projects would result in a less than significant cumulative impact related to exposure to hazardous materials. Moreover, the proposed project’s incremental contribution would not be significant. To reduce the proposed project’s impacts to below a level of significance and ensure a less than significant contribution to cumulative impacts, the proposed project would implement MM HAZ-1a through MM HAZ-1c and comply with all applicable policies related to transport, use, and disposal of hazardous materials (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-28). However, no mitigation is necessary; the impact would be less than significant without any mitigation. The main arterial streets that would serve as the most likely evacuation routes out of the central portion of the County include I-680, SR-24, and Ygnacio Valley Road. Planned uses as proposed by the cumulative projects are contemplated in the General Plan, would result in predominantly infill development, and would not significantly increase need for emergency services, including those related to wildfires. Furthermore, all construction would adhere to the regulations included in the California Fire Code that are designed to minimize the potential for the release of hazardous materials or uncontrolled fires. Once development is proposed, the County would assess the needs for fire protection services and inform efforts to improve or expand needed facilities. Cumulative development in the County primarily consists of residential and commercial development. New residential developments would contribute to increases in the County’s population. All development would, however, comply with emergency access requirements as projects condition. Furthermore, cumulative development in the County, including the proposed project, would not result in permanent road closures, impede established emergency access routes, or interfere with emergency response requirements. Moreover, the proposed project would fully comply with all applicable regulations (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-28). Therefore, the proposed project would not have a cumulatively considerable contribution to cumulative impacts. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 28 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx 1.5.8 - Hydrology Potential Effect Impact HYD-1 The proposed project would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-14). Findings Less than significant impact. Facts in Support of Findings The proposed project is designed to comply with all local, State, and federal requirements regarding water quality, including the County’s National Pollutant Discharge Elimination System (NPDES) permits, the Contra Costa Clean Water Program (CCCWP) and the Contra Costa County Ordinance Code Chapter 1014-4, which requires the preparation and implementation of a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP includes Best Management Practices (BMPs) to ensure reduction of pollutants from construction activities potentially entering surface waters. Additionally, implementation of the SWPPP would also prevent pollutants from entering the Ygnacio Valley Basin by preventing pollutants from moving off-site. Although construction and operation of the proposed project may have the potential to generate increased sedimentation, compliance with applicable policies and regulations would minimize the potential to degrade water quality in downstream water bodies to the maximum extent possible and result in less than significant impacts. Additionally, the on-site storm drain system has been designed to meet the County’s hydraulic requirements. On-site storage facilities of 2,800 cubic feet would be needed to mitigate the potential increase of post-development flows and to meet the hydromodification requirements. To meet this requirement, two underground storage vaults are proposed to capture, store, and release the post- development storm flow into the existing off-site storm drainage facilities. These two vaults are placed at the downstream ends of the on-site storm drains at the respective discharge points at Oak Road and Jones Road. The proposed project would utilize and integrate the bioretention technique and approach to meet the Low Impact Development (LID) treatments in compliance with the requirements set forth in the County C.3 Technical Guidance. The stormwater runoff from impervious surface is directed and passed through the bioretention areas and distributed evenly along a ponding area. Stormwater runoff will percolate through the sandy loam treatment soil and eventually be captured by the under drains and discharged into the underground storm drains. Given the physical constraints and limitations of the project site, stormwater treatment would be optimized by breaking up the new and/or replaced impervious areas in small drainage management areas and using drainage swales, curb openings, and bubble ups to convey the runoff to the treatment areas in paseos, landscape pockets between walkways/buildings and the center open space area on the project site. By implementing this approach, LID bioretention treatment areas are Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 29 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx dispersed throughout the site, enabling the project to treat 100 percent of the impervious surface with the bioretention measures (Draft EIR, Section 3.9, Hydrology and Water Quality, Pages 3.9-14– 16). For the above reasons, impacts would be less than significant. Potential Effect Impact HYD-2 The proposed project would not substantially decrease groundwater supplies or interfere substantially with groundwater recharge such that the proposed project may impede sustainable groundwater management of the basin (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-17). Findings Less than significant impact. Facts in Support of Findings Three irrigation wells located on the project site would be decommissioned prior to redevelopment. The proposed project would increase impervious surfaces by 36,420 square feet compared to existing conditions. However, the proposed project would incorporate LID techniques as described above in the Impact HYD-1 discussion. In addition, the Contra Costa Water District would be able to provide adequate water services to the project site and the rest of its service area during normal, dry, and multiple dry years, and no groundwater would be used. Thus, the project would not interfere substantially with groundwater supply, recharge, or groundwater management and impacts would be less than significant (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-17). Potential Effect Impact HYD-4 The proposed project would not be located in a flood hazard zone, tsunami, or seiche zone, or risk release of pollutants due to project inundation (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-22). Findings Less than significant impact. Facts in Support of Findings The Federal Emergency Management Agency (FEMA) designates the project site Zone X—area of minimal flood hazard. The closest designated 100-year flood hazard zone to the project site is Walnut Creek, located approximately 0.46 mile to the east. Therefore, the project site is not located within a recognized flood hazard area. The project site is not located near the ocean and as such would not be susceptible to inundation from a tsunami. The project site is not located near a large, enclosed body of water and as such would not be susceptible to inundation from a seiche. As a result, the project site would not be a risk for inundation from flooding, tsunami, or seiche and impacts are less than significant (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-22).

Findings Less than significant impact. Facts in Support of Findings The proposed project would not conflict with the County Watershed Program and the County’s NPDES program. The proposed project would be required to comply with the terms of the Construction General Permit, which require the preparation and implementation of an SWPPP that includes BMPs to ensure reduction of pollutants from construction activities potentially entering surface or groundwater. The project site has little potential for groundwater recharge due to shallow groundwater levels. In addition, the Contra Costa Water District would provide potable water to the project site and the project would not use groundwater as a water source. As a result, the project would not conflict with or obstruct a sustainable groundwater management plan (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-22). Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned ,and approved projects, would result in a less than significant cumulative impact related to hydrology, surface water quality, and groundwater quality (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-24). Findings Less than significant impact. Facts in Support of Findings Hydrology Cumulative impacts related to hydrology and water quality typically occur within a defined watershed. All properties on the cumulative projects list in Table 3-1 of the Draft EIR are located within the Walnut Creek Watershed, and all respective surface water in the watershed eventually discharges into Suisun Bay. Some cumulative projects are located within Contra Costa County, including the project, and would be required to comply with the CCCWP and Contra Costa County General Plan policies, which prevent a project from increasing off-site surface water flow from existing conditions and ensure that projects adhere to best practices during construction to prevent pollutants from being carried off-site. Some cumulative projects are located in the cities of Walnut Creek and Pleasant Hill. Cumulative development in the City of Walnut Creek would be required to demonstrate consistency with the City of Walnut Creek General Plan and applicable codes, ordinances, and policies related to preventing pollutants from being conveyed off-site. Cumulative development in the City of Pleasant Hill would be required to demonstrate consistency with the City Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 31 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx of Pleasant Hill General Plan and applicable codes, ordinances, and policies related to preventing pollutants from being conveyed off-site. The combination of these policies and best practices would prevent significant cumulative impacts to hydrology (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-23). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project would not have a significant incremental contribution to cumulative impacts. To ensure a less than significant contribution to cumulative impacts, the proposed project will be required to implement all applicable policies and best practices, as described in Section 3.9, Hydrology and Water Quality, during the design review process. Therefore, the proposed project’s contribution to cumulative impacts would be considered less than significant. Water Quality The geographic context for consideration of cumulative impacts related to surface water quality is the Walnut Creek Watershed. All cumulative projects, including the project, would involve short- term construction and long-term operational activities that would have the potential to degrade water quality in downstream water bodies, including Walnut Creek and Suisun Bay. All cumulative project construction would be required to obtain a Construction General Permit from the California State Water Resources Control Board (State Water Board), which would require preparation of a SWPPP that would control potential discharges of contaminants into Walnut Creek and Suisun Bay. Operations of these cumulative projects would be required to comply with the CCCWP, County Ordinance Code regarding stormwater, or the cities of Walnut Creek and Pleasant Hill applicable codes, ordinances, and policies related to water quality. Development in the County would be required to implement similar measures in accordance with adopted regulations, while projects would be subject to the Construction General Permit if applicable. Development in the City of Walnut Creek would be required to implement similar measures in accordance with adopted regulations, while projects would be subject to the Construction General Permit if applicable. Development in the City of Pleasant Hill would be required to implement similar measures in accordance with adopted regulations while projects would be subject to the Construction General Permit if applicable (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-23). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project’s compliance with the requirements identified above would ensure that the proposed project would not have a significant incremental contribution to cumulative impacts. The geographic context for consideration of cumulative impacts related to groundwater quality and management is the Ygnacio Valley Groundwater Basin. All cumulative projects, including the proposed project, would involve short-term construction and long-term operational activities that would have the potential to impact groundwater quality and management. All cumulative project construction would be required to obtain a Construction General Permit from the State Water Board, which would require preparation of a SWPPP that would control pollutants that could seep into groundwater. Operations of cumulative projects in Contra Costa County would be required to comply with the CCCWP and the County Ordinance Code regarding groundwater. Operations of cumulative projects in Walnut Creek would be required to comply with the CCCWP and the City of Walnut Creek Ordinance Code regarding groundwater. Operations of cumulative projects in Pleasant Hill would be required to comply with the CCCWP and the City of Pleasant Hill Ordinance Code regarding Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 32 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx groundwater (Draft EIR, Section 3.9, Hydrology and Water Quality, Page 3.9-24). Accordingly, potential cumulative impacts would be less than significant. Moreover, the proposed project’s compliance with the requirements identified above would ensure that the proposed project would not have a significant incremental contribution to cumulative impacts. 1.5.9 - Land Use and Planning Potential Effect Impact LAND-1 The proposed project would not physically divide an established community (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-15). Findings Less than significant impact. Facts in Support of Findings The development of the proposed townhouse condominium buildings would not impair access to any established community, impede travel or otherwise constitute division of an established community. Rather, the proposed project would establish connectivity and pedestrian access between Jones Road and Oak Road by providing private street and walkable landscaped open space (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-16). Potential Effect Impact LAND-2 The proposed project would not cause a significant environmental impact due to conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-16). Findings Less than significant impact. Facts in Support of Findings Strict conformity with all aspects of a general plan is not required. A lead agency can find a proposed project consistent with its local general plan if the project furthers one or more policies and does not obstruct other policies. Perfect conformity with every plan policy is not required. Consistency of the proposed project with applicable General Plan policies is evaluated in Table 3.10-5 on Page 3.10-17 through Page 3.10-27 of the Draft EIR. The General Plan designates the project site as MH, which allows for densities between 22.0 and 29.9 multiple-family units per net acre. The proposed project would develop 125 townhouse condominiums, resulting in a total of 237,816 square feet of net new habitable construction on 5.94 acres or a net density of 26.3 dwelling unit per acre. Therefore, the density and use would be consistent with the General Plan land use designation. The proposed project would be consistent with the General Plan goals and policies relative to providing residences in unincorporated area of the County. The project site is currently zoned R-15, M-17, and M-29. The proposed project would rezone the entire site to P-1 to allow flexibility with respect to use, building types, lot size, and open space while Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 33 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx ensuring the proposed project complies with the General Plan and requirements as set forth in the Ordinance Code. The proposed rezone is intended to achieve project consistency with the Contra Costa County Zoning Ordinance. Additionally, the proposed project would be consistent with County parking standards and with Ordinance Code Section 82-16.412, which sets forth the amounts of bicycle parking that a project must provide. Overall, the proposed project is consistent with the General Plan and would not conflict with applicable land use plans, policies, or regulations of the General Plan or the Ordinance Code that were adopted for the purpose of avoiding or mitigating an environmental effect (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-16). Accordingly, impacts are less than significant. Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in a less than significant cumulative impact related to land use and planning (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-29). Findings Less than significant impact. Facts in Support of Findings The geographic scope of the cumulative land use analysis is the unincorporated area of Contra Costa County with a focus on the area surrounding the project site. Land use decisions for both the proposed project and for some of the other cumulative projects are made at the County level. Some cumulative projects are located in the cities of Walnut Creek and Pleasant Hill, and land use decisions for those projects are made at the relevant city level. Development within the unincorporated County is governed by the General Plan and the Ordinance Code, which ensure logical and orderly development and require discretionary review to ensure that projects do not result in environmental impacts due to inconsistency with the General Plan and other land use planning regulations. This would minimize any cumulative impact related to division of an established community. Development within the unincorporated County would be required to demonstrate consistency with the General Plan and applicable codes, ordinances, and policies. Development in the City of Walnut Creek would be required to demonstrate consistency with the City of Walnut Creek General Plan and applicable codes, ordinances, and policies. Development in the City of Pleasant Hill would be required to demonstrate consistency with the City of Pleasant Hill General Plan and applicable codes, ordinances, and policies. This would ensure that these cumulative projects comply with applicable planning regulations (Draft EIR, Section 3.10, Land Use and Planning, Page 3.10-28–29). As such, development is not likely to create significant land use conflicts or divide existing communities. For these reasons cumulative impacts with respect to land use would be less than significant. The proposed project’s incremental contribution to cumulative land use impacts would also not be significant. As discussed under Impacts LAND-1 and LAND-2, implementation of the proposed project would not physically divide an established community or conflict with any land use plan, Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 34 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx policy, or regulation, adopted for the purpose of avoiding or mitigating an environmental effect. Accordingly, the proposed project ’s contribution to cumulative impacts would also be less than significant. 1.5.10 - Noise Potential Effect Impact NOI-3 The proposed project would not result in generation of excessive groundborne vibration or groundborne noise levels (Draft EIR, Section 3.11, Noise, Page 3.11- 18–21). Findings Less than significant impact. Facts in Support of Findings Contra Costa County has not adopted criteria for construction or operational groundborne vibration impacts. Therefore, the Federal Transit Administration (FTA ) construction vibration impact criteria are utilized. The FTA threshold of 0.2 inches per second (in/sec) peak particle velocity (PPV) is the potential damage criteria threshold for buildings of non-engineered timber and masonry construction. For operational impacts, a significant impact will occur if project ongoing activities would produce groundborne vibrations that are perceptible without instruments by a reasonable person at the property lines of the site. Impact equipment, such as pile drivers, are not expected to be used during construction of the project. Therefore, of the variety of equipment used during construction of the project, the small vibratory rollers that would be used in the site preparation phase of construction would produce the greatest groundborne vibration levels. Small vibratory rollers produce groundborne vibration levels ranging up to 0.101 in/sec PPV at 25 feet from the operating equipment. The nearest off-site receptor to where the heaviest construction equipment would operate are the multi-family residential homes, approximately 20 feet south of the nearest construction footprint for the project. As measured at the nearest receptor, operation of a small vibratory roller could result in groundborne vibration levels up to 0.141 in/sec PPV. This is below the FTA’s damage threshold criteria of 0.2 in/sec PPV for non-engineered timber and masonry buildings. Implementation of the project would not include any permanent sources of vibration that would expose persons in the project vicinity to groundborne vibration levels that could be perceptible without instruments at any existing sensitive land use in the vicinity of the project site (Draft EIR, Section 3.11, Noise, Page 3.11-21–22). Potential Effect Impact NOI-4 The proposed project would not expose people residing or working in the project area to excessive noise levels for a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport (Draft EIR, Section 3.11, Noise, Page 3.11-22).

Facts in Support of Findings The project site is not located within the vicinity of a private airstrip. The nearest public airport to the project site is the Buchanan Field Airport, located approximately 4.5 miles north of the project site. According to the airport’s noise contour map, the project site is located outside of the 65 A- weighted decibels (dBA) Community Noise Equivalent Levels (CNEL) airport noise contours. While aircraft noise is occasionally audible on the project site from aircraft flyovers, aircraft noise associated with nearby airport activity would not expose people to residing or working near the project site to excessive noise levels. Therefore, implementation of the project would not expose persons residing or working in the project vicinity to noise levels from airport activity that would be in excess of normally acceptable standards for the proposed land use development (Draft EIR, Section 3.11, Noise, Page 3.11-22). 1.5.11 - Population and Housing Potential Effect Impact POP-1 The proposed project would not induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure) (Draft EIR, Section 3.12, Population and Housing, Page 3.12-8). Findings Less than significant impact. Facts in Support of Findings The proposed project would add an estimated 357 persons to the County’s population. This would represent an increase of 0.2 percent relative to the unincorporated population of 174,423. This amount of population growth would be within the General Plan’s 2020 population and dwelling projections for the unincorporated area and, therefore, would not be considered substantial. Furthermore, it would also be within ABAG’s 2020-2040 regional population growth projections. The proposed project is exclusively residential; it would not create new permanent employment opportunities. Thus, no indirect population growth from new employment would occur. The project site has been developed since the 1930s and is located within an urbanized area of the unincorporated County. It is served with urban infrastructure and utilities including potable water, sewer, storm drainage, electricity, and natural gas. As such, the proposed project would not remove a barrier of growth through the extension of infrastructure or utilities to an unserved area. Impacts would be less than significant.

Findings No impact. Facts in Support of Findings Impacts related to displacement of people or housing necessitating replacement housing are limited to operational impacts. No respective construction impacts would occur. The site contains two existing residential units that are occupied by the property owners’ family members serving as caretaker and security for the property and existing improvements. Removal of these existing uses would not result in the displacement of substantial numbers of persons or housing (Draft EIR, Section 3.12, Population and Housing, Page 3.12-9). Potential Effect Cumulative Impact Cumulative impacts associated with the proposed project, in conjunction with other past, present, planned, and approved projects, related to population growth, both direct and indirect, as well as population and housing displacement, would be considered less than significant (Draft EIR, Section 3.12, Population and Housing, Page 3.12-9). Findings Less than significant impact. Facts in Support of Findings The geographic scope of the cumulative population and housing analysis is Contra Costa County. As of 2021, the County was estimated to have a population of 1,153,854, with unincorporated areas having a population of 174,423. Cumulative projects in conjunction with the proposed project would add residential units and population to the County. None of the listed projects would substantially displace housing units or people within the County. In fact, implementation of the cumulative projects would result in a net increase of housing in the County. The County further requires development that may impact housing to include affordable housing units or pay a related impact fee (see Regulatory Setting). Therefore, cumulative impacts associated with population and housing displacement would be less than significant (Draft EIR, Section 3.12, Population and Housing, Page 3.12-9). The proposed project would add 357 persons to the County’s population, which would represent growth of less than 0.01 percent of the County’s population and 0.02 of the unincorporated population. As such, there would not be substantial direct population growth associated with the proposed project in conjunction with the cumulative projects.

Therefore, cumulative impacts would be no impact. 1.5.12 - Public Services and Recreation Potential Effect Impact PUB-1 The proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered fire protection facilities, need for new or physically altered fire protection facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for fire protection (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-17). Findings Less than significant impact. Facts in Support of Findings Four fire stations are located within approximately 2 miles of driving distance of the project site: Station No. 1, located at 1330 Civic Drive in Walnut Creek, is approximately 1.7 miles (driving distance) south of the project site; Station No. 2, located at 2012 Geary Road in Pleasant Hill, is approximately 1.4 miles (driving distance) west of project site, Station No. 5, located 205 Boyd Road in Pleasant Hill, is approximately 1.9 miles (driving distance) north of the project site; and Station No. 10, located at 2955 Treat Boulevard in Concord, is approximately 2.2 miles (driving distance) northeast of the project site. Using an average travel speed of 35 miles per hour (mph), a fire engine would be able to reach construction areas at the project site from Station No. 2 (approximately 1.4 miles of driving distance) in 2 minutes and 24 seconds, which is under the 5-minute response standard set by the County General Plan. As part of project construction, the proposed project would comply with the CBC, which is adopted by the Ordinance Code. In compliance with the California Fire Code, Part 9 of the CBC, during construction the proposed project would follow standards for fire safety related to provision of fire apparatus access and acquisition of building permits. Specifically, CBC Section 105.7.17 requires plans be submitted and a permit is required to install, improve, modify, or remove public or private roadways, driveways, and bridges for which Fire District access is required by the Fire Code; this would ensure adequate driveway/entry turning radius, height clearance, and fire hydrant access for fire trucks and engines at the project site during construction. In addition, CBC Section 105.7.18 requires plans be submitted to the Fire Code Official for all land developments or for the construction, alteration, or renovation of a building within the jurisdiction where a building permit is required; this would ensure that construction and alteration would not obstruct CCCFPD from delivering adequate levels of fire protection services. With an adequate fire engine response time to the project site and adherence to the aforementioned CBC Code sections, construction of the proposed project would not create the need for new or altered fire protection facilities (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-17). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 38 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx The operation of new townhouses on the project site would result in new residents at the project site and could in turn result in an increase in calls for fire protection and emergency medical services. As noted above, Fire Station No. 2, at 2012 Geary Road, is approximately 1.4 miles west of the project site, and could reach the site within 2 minutes and 24 seconds, which is below the 5- minute response standard set by the General Plan. As part of project operation, the proposed project would comply with the CBC, which is adopted by the Ordinance Code. Specifically, in compliance with the California Fire Code, Part 9 of the CBC, during operation the proposed project would follow standards for fire safety such as fire flow requirements for buildings, fire hydrant location and distribution criteria, automated sprinkler systems, and fire-resistant building materials. Primary vehicle access to the project site would be from a driveway on Oak Road and a driveway on Jones Road. Oak Road is a public local street under the jurisdiction of the City of Walnut Creek. It runs north–south along the project site east frontage. Jones Road is a public County local street that runs along the project site west frontage. Thus, during project operation, emergency vehicles would not have difficulty accessing the project site. As such, it is not expected that the proposed project would adversely affect response times or increase the use of existing fire protection or emergency medical response facilities such that substantial physical deterioration, alteration, or expansion of these facilities would be required, thereby triggering environmental impacts. Furthermore, the project applicant would be required to pay applicable fees toward fire protection facilities and apparatus so that the CCCFPD can maintain fire safety standards. With an adequate fire engine response time to the project site, adherence to the aforementioned CBC Code sections, adequate project site access, and payment of impact fees to the CCCFPD, operation of proposed project would not create a need to construct new or expand existing fire protection or emergency medical services facilities (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-18). Potential Effect Impact PUB-2 The proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered police protection facilities, need for new or physically altered police protection facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for police protection (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-18). Findings Less than significant impact. Facts in Support of Findings The nearest Sheriff station to the project site is the Valley Station at 150 Alamo Plaza Unit C, located 6.7 miles (driving distance) southeast of the project site; however, response is likely to originate from Sheriff Deputies or Walnut Creek police officers pursuant to mutual aid patrolling the local beat. If response calls originated from the Valley Station, response would be approximately 11 minutes and 29 seconds to the project site, assuming an average travel speed of 35 mph driving speed. During construction, the proposed project would also implement security measures such as provision of a Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 39 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx project-boundary fence to prohibit access to persons other than construction personnel. With an adequate police response time to the project site and provision of adequate security measures, construction of the proposed project would not create the need for new or altered police protection facilities. The operation of new townhouses on the project site would result in new residents at the project site and could in turn result in an increase in calls for police protection services. The Office of the Sheriff does not set a specific goal for emergency call response times. However, County General Plan Policy 7-59 indicates that when making staffing and beat configuration decisions, the Sheriff should strive for a maximum response time for Priority 1 or 2 calls of 5 minutes for 90 percent of all emergency responses in central business district, urban, and suburban areas. This General Plan Policy indicated response time is a goal, not a requirement. The proposed project would increase the population of unincorporated Contra Costa County by approximately 357 persons. Accordingly, the proposed project would require 55 square feet of Sheriff station space. This increased demand for Sheriff station space represents approximately 1 percent of the Valley Station’s existing square footage and, thus, represents a nominal increase in demand. The Office of the Sheriff did not indicate that the proposed project would result in the need for new or expanded Sheriff facilities in order to maintain acceptable service ratios, response times, or other performance objectives. Furthermore, the project applicant would be required to pay applicable fees to the Office of the Sheriff to help provide for the costs associated with a police facilities building and equipment to serve additional demands for police services. With adequate project site access and payment of impact fees to the Office of the Sheriff, operation of the proposed project would not create a need to construct new or expand existing police protection facilities (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-19–20). Potential Effect Impact PUB-3 The proposed project would not result in substantial adverse physical impacts associated with the provision of new or physically altered school facilities, need for new or physically altered school facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios or other performance objectives for schools (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-20). Findings Less than significant impact. Facts in Support of Findings The project applicant would be required to pay development impact fees to the Walnut Creek School District (WCSD) and Acalanes Union High School District (AUHSD). Pursuant to Government Code Section 65995, payment of adopted development fees is considered “full and complete mitigation” for impacts to school facilities and local governments are prohibited from assessing additional fees or exactions for school impacts. With payment of impact fees to the WCSD and AUHSD, operation of the proposed project would not create a need to construct new or expand existing school facilities (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-21).

Findings Less than significant impact. Facts in Support of Findings Impacts related to provision of and need for construction of new or expanded library facilities are limited to operational impacts. The General Plan does not include a standard or goal for the provision of library services; however, for informational purposes, the County generally provides approximately 319 gross square feet of library space per 1,000 residents. The proposed project’s approximately 357 residents is a nominal increase compared with the existing County population of approximately 1.1 million residents served by the Contra Costa County Library system. The proposed project’s estimated increase in persons would represent an increase of less than 1 percent relative to the existing residents served by the Contra Costa County Library system. As such, the County’s provision of library space per 1,000 residents would not be affected by implementation of the proposed project. Furthermore, the County Librarian anticipates that the proposed project would not have a noticeable effect on the ability of the County Library system to provide library services. With adequate relevant library system capacity, operation of proposed project would not create a need to construct new or expand existing library facilities (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-22). Potential Effect Impact REC-1 The proposed project would not increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-22). Findings Less than significant impact. Facts in Support of Findings Impacts related to increased use of existing parks and recreational facilities are limited to operational impacts. Goal 9-K of the General Plan Open Space Element seeks to achieve a level of park facilities equal to 4 acres per 1,000 population or 0.004-acre per person. With a County population of 1,153,854 persons (2021) and approximately 46,624 acres of parks (State, County, East Bay Regional Park District [EBRPD], and local parks), the current ratio is approximately 40.4 acres per 1,000 population, far exceeding the County’s goal. The proposed 125 residential units would be Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 41 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx expected to result in a permanent population of 357 persons, resulting in the need for 1.428 acres of parkland to assist in the County’s parkland goal. Nearby recreational facilities total nearly 7,000 acres in available existing parks. Given the wide range of proposed on-site and existing proximate parks and recreational facilities available to project-related residents, the recreational needs of the proposed project’s anticipated 357 new residents would be dispersed across these nearly 7,000 total acres of parkland and, thus, not result in an increased use that would cause substantial physical deterioration of existing neighborhood and regional parks or other recreational facilities. Additionally, the proposed project is subject to the County’s Park Impact Fee. The Park Impact Fees would be collected to fund the acquisition and development of parks in Contra Costa County to serve unincorporated County residents in lieu of providing the required acreage on the project site (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-23). Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in less than significant cumulative impacts related to public services and recreation (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-27). Findings Less than significant impact. Facts in Support of Findings Cumulative development could increase population within the proposed project vicinity by approximately 2,910 persons. The proposed project would add an estimated 357 persons to the County’s population (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-24). Fire Protection Facilities The cumulative increase in population could result in an increased demand for fire protection facilities. To help offset the increased demand, the cumulative projects would be required to pay all applicable fees to the CCCFPD. All developments would also adhere to the California Fire Code, Part 9 of the CBC in terms of meeting standards for fire safety such as fire flow requirements for buildings, fire hydrant location and distribution criteria, automated sprinkler systems, and fire- resistant building materials. With adherence to CBC sections and payment of applicable fees, cumulative projects would not result in need for new or altered fire protection or emergency medical facilities. All cumulative projects would be required to comply with city and county ordinances and General Plan policies that address fire protection services. Therefore, cumulative impacts would be less than significant. Moreover, the proposed project’s incremental contribution to less than significant cumulative impacts would not be significant. As discussed under Impact PUB-1, implementation of the proposed project would not create a need for new or physically altered facilities to provide fire protection services to the service area. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 42 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Police Protection Facilities The cumulative increase in population could result in an increased demand for police protection facilities. To help offset the increased demand for police protection facilities, the cumulative projects would be required to pay applicable fees to the Office of the Sheriff. All developments would also be reviewed for impacts on law enforcement services and would be required to address any potential impacts with mitigation. Because demand for law enforcement services is highly dependent on a number of factors that vary substantially by project (clientele, hours of operation, crime prevention measures, etc.), it is unlikely that there would be substantial overlap in demand that would result in a cumulatively significant impact such that new police protection facilities are necessary (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-25). All cumulative projects would be required to comply with city ordinances and General Plan policies that address police protection services. Therefore, cumulative impacts would be less than significant. Moreover, the proposed project’s incremental contribution to less than significant cumulative impacts would not be significant. As discussed under Impact PUB-2, implementation of the proposed project would not create a need for new or physically altered facilities to provide fire protection services to the service area. School Facilities The cumulative increase in population could result in an increased demand for school facilities. Other cumulative projects do not include any educational facilities. All cumulative developments would be required to pay development impact fees impact fees toward the two applicable school districts. Under State law, this is the exclusive means of mitigating impacts to school facilities due to increased enrollment. As part of the project entitlement process, the cumulative project applicants would be responsible for paying their fair share of these school facility fees. The payment of school impact fees would ensure that school facilities can accommodate future students. Therefore, cumulative impacts would be less than significant. As discussed in impact PUB-3 the proposed project will be required to pay school impact fees and this requirement is considered to fully mitigate impacts on school facilities. Therefore, impacts of the General Plan on school facilities are not cumulatively considerable. Library Facilities The cumulative increase in population could in turn result in an increased demand for library facilities. The County generally provides approximately 319 gross square feet of library space per 1,000 residents. With development of the other cumulative project in conjunction with the proposed project, the County’s provision of library space per 1,000 residents would need to be increased by approximately 1,042 square feet. The construction of the new Pleasant Hill Library (scheduled to be completed in 2022) would more than adequately address this need. Therefore, cumulative impacts are less than significant (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-26). The proposed project’s incremental contribution to less than significant cumulative impacts would not be significant. The proposed project would result in growth of less than 0.01 percent of the County’s population and 0.02 of the unincorporated population, which would not significantly increase demand for library services. For these reasons, impacts on library facilities are not cumulatively considerable and the cumulative impact would be less than significant.

To help offset that demand, Cumulative Project 1, listed in Table 3-1 of the Draft EIR, would be subject to the County Park Impact Fee. The Park Impact Fees would be collected to fund the acquisition and development of parks in Contra Costa County to serve unincorporated County residents in lieu of providing the required acreage on the project site. Other cumulative projects that are within the City of Walnut Creek and City of Pleasant Hill would similarly be required to provide parkland or pay development fees. With payment of Park Impact Fees by the cumulative projects, there would be a less than significant cumulative impact related to potential increased use and physical deterioration of existing parks and recreational facilities. The California Department of Parks and Recreation (DPR), EBRPD, Contra Costa County, and cities in the proposed project vicinity maintain State, regional, and local community parks, trails, and recreational facilities for public use throughout Contra Costa County. County park standards are established in the County’s General Plan. Specifically, Goal 9-K of the General Plan Open Space Element, seeks to achieve a level of park facilities equal to 4 acres per 1,000 population or 0.004- acre per person. With a County population of 1,153,854 persons (2021) and approximately 46,624 acres of parks (State, County, various cities, and EBRPD), the current ratio is approximately 40.4 acres per 1,000 population, far exceeding the County goal. The cumulative projects would add approximately 2,910 residents to the area. However, the current high ratio of parks to population would not be significantly impacted by the added residents (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-26). Therefore, the proposed project’s impacts on park and recreation facilities are not cumulatively considerable and the cumulative impact would be less than significant. 1.5.13 - Transportation Potential Effect Impact TRANS-1 The proposed project would not conflict with a program plan, ordinance, or policy of the circulation system, including transit, roadway, bicycle and pedestrian facilities (Draft EIR, Section 3.14, Transportation, Page 3.14-14). Findings Less than significant impact. Facts in Support of Findings Bicycle Facilities There are no existing bike lanes on Jones Road. However, there is a pedestrian/bike trail, Iron Horse Regional Trail, located approximately 1,500 feet east of the project site. The bike trail provides access to the Pleasant Hill/Contra Costa Centre BART station. There is also another pedestrian/bike trail, Contra Costa Canal Trail, located approximately 450–600 feet south of the project site and crossing Oak Road and Jones Road. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. The project would not affect existing or planned bicycle facilities.

Oak Road has planned Class II facilities in the vicinity of the project. The planned facilities would be located on Oak Road between Treat Boulevard and the Contra Costa Canal Trail. The four on-street parking spaces proposed along Oak Road would not result in a conflict with future construction of this facility. The Iron Horse Regional Trail, a pedestrian/bike trail, is located approximately 1,500 feet east of the project site. The Iron Horse Regional Trail extends from Marsh Drive in Concord to Santa Rita Road in Pleasanton. The Iron Horse Regional Trail provides access to the Pleasant Hill/Contra Costa Centre BART station. There is also another trail, Contra Costa Canal Trail, located approximately 650 feet south of the project site and crossing Jones Road. The Contra Costa Canal Trail extends from Muir Road in Martinez to Willow Pass Road in Concord. The Contra Costa Canal Trail provides access to Walden Park and the Iron Horse Regional Trail. The Contra Costa Canal Trail also provides good bicycle connectivity to the project site and the Seven Hills School. According to the City of Walnut Creek Bicycle Plan, there are plans to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. Pedestrian Facilities There are sidewalks on the east side of Jones Road within the vicinity of the project site. There are also sidewalks on both sides of Oak Road and Treat Boulevard so that residents at the project site can easily walk to the Pleasant Hill/Contra Costa Centre BART station. The traffic signals at the Oak Road/Jones Road and Oak Road/Treat Boulevard intersections include crosswalks with pedestrian signal heads to facilitate crossing the street. The Iron Horse Regional Trail and Contra Costa Canal Trial described previously are Class I pedestrian/bicycle facilities within project proximity. There are no pedestrian improvement plans along Jones Road or Oak Road along the project frontage, and the project would not affect existing or planned pedestrian facilities. The Seven Hills School is located within a 1-mile radius of the project site, and the Contra Costa Canal Trail provides a pedestrian connection to the school from the project site. Transit Facilities The site is served by several County Connection bus routes: 7, 9, 11, 14, 15, and 311. The project site is located with 0.5 mile of a major transit stop, the Pleasant Hill/Contra Costa Centre BART station, which is located north of the project site. The closest bus stop to the project site is located at Oak Road and Walden Park, approximately 970 feet south of the project site. There are sidewalks on Oak Road that provide connectivity to the bus stop. The Pleasant Hill/Contra Costa Centre BART station also provides other bus route connections in addition to other County Connection lines. AC Transit, Solano Express, FAST, and Wheels Express provide connecting transit routes at the Pleasant Hill/Contra Costa Centre BART station (refer to Exhibit 3.14-5 and Table 3.14-6). Paratransit services could also be provided to the residents at the project site. County Connection LINK serves Pleasant Hill, Walnut Creek, Concord, Lafayette, and other central Contra Costa cities. Paratransit service rides are provided within 1.5 miles of a bus stop or train station (Draft EIR, Section 3.14, Transportation, Page 3.14-15).

Findings Less than significant impact. Facts in Support of Findings In accordance with new CEQA Guidelines, the County has transitioned from intersection Level of Service (LOS) to VMT for CEQA transportation analysis. The Contra Costa County Transportation Analysis Guidelines (County TAG ) also include screening criteria for projects that are expected to result in less than significant VMT impacts. According to the County TAG, a project is expected to result in a less than significant VMT impact if the proposed project is located within 0.5 mile of an existing major transit stop or an existing stop along a high-quality transit corridor. The Pleasant Hill/Contra Costa Centre BART station is located within 0.5 mile of the project site. In addition, there are bicycle and pedestrian facilities between the project site and the Pleasant Hill/Contra Costa Centre BART station, such as continuous sidewalks along Jones Road and Oak Road that connects to the project site to this BART station. At a normal walking pace, it would take approximately 5 minutes to walk from the project site to this BART station (Draft EIR, Section 3.14, Transportation, Page 3.14-17). The Iron Horse Regional Trail and the Contra Costa Canal Trail also provide access to the Pleasant Hill/Contra Costa Centre BART station. There are also bike racks and bike lockers at the BART station for bicyclists to park their bicycles. Furthermore, the BART system provides quality regional connection to major employment destinations within the Bay Area (i.e., Oakland, San Francisco) and will soon connect to the San José area as well. The Pleasant Hill/Contra Costa Centre BART station also connects to local bus routes that are provided by County Connection. These local bus routes include County Connection weekday routes 7, 9, 11, 14, 15, and 18, County Connection weekend routes 311 and 316, County Connection Early Bird Express routes 702 and 712, Solano Express Blue and Yellow lines, FAST Blue line, Wheels Bus line 70X, and Alameda-Contra Costa Transit District (AC Transit) route 702. The regional transit connectivity available to the project residents, along with availability of bicycle parking on-site and bicycle and pedestrian facilities in the vicinity of the project site, would reduce residents’ need to drive (Draft EIR, Section 3.14, Transportation, Page 3.14-18). Potential Effect Impact TRANS-3 The proposed project would not substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment) (Draft EIR, Section 3.14, Transportation, Page 3.14-18).

There would also be a driveway that would connect to the project site on Oak Road. The new driveways on Jones Road and Oak Road would be 26 feet wide, which could accommodate two-way traffic and meet Fire Code standards (Draft EIR, Section 3.14, Transportation, Page 3.14-19). The project access points would remain free and clear of any obstructions that would materially and adversely affect sight distance, thereby ensuring that exiting vehicles can see pedestrians on the sidewalk and other vehicles traveling on adjacent roadways. As designed, landscaping and parking would not conflict with a driver’s ability to locate a gap in traffic and see oncoming pedestrians and bicyclists. Adequate corner sight distance (sight distance triangles) would be provided at all site access points in accordance with the County standards. The line of sight for vehicles exiting the driveway and vehicles traveling northbound on Jones Road are clear and visible. Vehicles exiting the driveway would be visible to the vehicles traveling southbound on Jones Road and Oak Road. There are existing red curbs on both sides of each driveway to provide adequate visibility for vehicles exiting the project site. The proposed project would not substantially increase hazards due to any design features. The proposed project would provide new streets and alleys within the project site that lead to each unit. Each unit would have its own driveway and a garage. According to the Ordinance Code, the minimum two-way drive aisle width for multi-family uses is 20 feet and 26 feet when portion of the building has human occupancy located more than 30 feet above the access road. The site plan shows the appropriate drive aisle widths within the project site. The site plan demonstrates the proposed project would provide adequate space for garbage trucks, loading trucks and emergency vehicles to circulate throughout the project site (Draft EIR, Section 3.14, Transportation, Page 3.14-19). Potential Effect Impact TRANS-4 The proposed project would not result in inadequate emergency access (Draft EIR, Section 3.14, Transportation, Page 3.14-19). Findings Less than significant impact. Facts in Support of Findings Emergency vehicle access would be provided via the two proposed driveways on Jones Road and Oak Road. The new driveways would be 26 feet wide, which can accommodate two-way traffic and provide adequate access for emergency vehicles (Draft EIR, Section 3.14, Transportation, Page 3.14- 19). Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in less than significant cumulative impacts related to transportation (Draft EIR, Section 3.14, Transportation, Page 3.14-20).

Facts in Support of Findings The geographic scope of the cumulative transportation analysis is the roadway network and the transit, pedestrian, and bicycle facilities in the vicinity of the project site. All cumulative projects would be required to comply with County and local ordinances and General Plan policies that address potential impacts related to transportation. For these reasons, cumulative impacts with respect to transportation and traffic would be less than significant. Moreover, the proposed project’s incremental contribution to cumulative traffic impacts would not be significant. As discussed in impacts TRANS-1 through TRANS-4, the proposed project would have a less than significant impact on intersection operations, public transit, bicycles, and pedestrians. Therefore, the proposed project would not have a cumulatively considerable contribution. The proposed project’s VMT would not result in a significant impact for VMT and therefore would not have a considerable cumulative contribution. The proposed project would implement recommended TDM measures that would facilitate further reductions in VMT by encouraging use of alternate transportation modes. The proposed project’s VMT would not result in a significant impact for VMT and therefore would not have a considerable cumulative contribution. The proposed project would provide adequate emergency access via the two proposed driveways on Jones Road and Oak Road and impacts would be less than significant. Therefore, the proposed project would not have a cumulatively considerable contribution to cumulative impacts (Draft EIR, Section 3.14, Transportation, Page 3.14-20). 1.5.14 - Utilities and Service Systems Potential Effect Impact UTIL-1 The proposed project would not require or result in the relocation or construction of new or expanded water, wastewater treatment or stormwater drainage, electric power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-18). Findings Less than significant impact. Facts in Support of Findings Water Because the project site is currently served by the Contra Costa Water District (CCWD), its water consumption is factored into the Urban Water Management Plan (UWMP’s) planning projections. Thus, adequate water supplies are available to serve the proposed project and no new or expanded water treatment or conveyance facilities would be required. Additionally, the CCWD provided a letter to the applicant dated November 10, 2020, confirming it could serve the proposed project and providing standard requirements for new service connections (e.g., separate metering of domestic, fire, and irrigation). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 48 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Wastewater Treatment The proposed project would install a new on-site sewer collection system consisting of 8-inch diameter pipes that would discharge via service lateral to an existing 18-inch diameter sewer line in Jones Road. Central Contra Costa Sanitary District (Central San) provided comments to the applicant dated August 4, 2020, confirming it could serve the proposed project providing standard requirements for new service connections (e.g., payment of connection fees). Central San would contain sufficient capacity to serve all aspects of the project, and a new or expanded wastewater treatment facility would not be required. Stormwater Drainage There would be a net increase of 40,136 square feet of impervious surfaces relative to existing conditions (155,600 square feet vs. 195,736 square feet). The proposed project would result in 2.2 acres of impervious surfaces draining to Oak Road and 3 acres of impervious surfaces draining to Jones Road. Thus, there would be a net decrease in drainage to Oak Road and a net increase in drainage to Jones Road. The proposed project would install an on- site storm drainage system. Inlets would capture surface runoff, where it would enter an underground piping system ranging from 12 to 18 inches in diameter that would convey stormwater to bioretention basins or hydromodification vaults. The basins and vaults would be designed to promote percolation into the soil and would release runoff into the municipal drainage system at a rate no greater than the pre-development condition of the project site. In accordance with applicable provisions of Section C.3 of the San Francisco Bay RWQCB Municipal Regional Permit (Order No. R2-2015-0049, NPDES Permit No. CAS612008) (or more recent permit) the proposed project would implement LID stormwater management methods into the on-site storm drainage system consisting of rainwater harvesting and use, infiltration, evapotranspiration, or biotreatment. Collectively, these measures would serve to slow, reduce, and meter the volume of runoff leaving the project site and ensure that downstream storm drainage facilities are not inundated with project-related stormwater (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-18–19). Electric Power Electricity services would be provided by PG&E. Existing overhead utility lines along the proposed project frontage on Oak Road and Jones Road would be relocated underground. Impacts related to energy use from electric power would be less than significant (Draft EIR, Section 3.5, Energy, Page 3.5-11). Therefore, the proposed project would not result in the relocation or construction of new or expanded electric power facilities (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15- 20). Natural Gas No gas service would be provided to the proposed project. As discussed in Section 3.5, Energy, the proposed project would not result in the use of any natural gas. Therefore, there would be no impacts related to natural gas facilities (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-20).

The proposed project would not require the construction or expansion of telecommunications facilities because it is located in an urban area that already contains sufficient telecommunications facilities (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-20). Potential Effect Impact UTIL-2 The proposed project would have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple-dry years (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-20). Findings Less than significant impact. Facts in Support of Findings Impacts related to sufficient water supplies are limited to operational impacts. The proposed project would demand a net increase of 64,843 gallons of water per day, which equates to 72.6 acre-feet per year. This amount of water represents less than 1 percent of both CCWD’s 2025 average water year supply value of 216,600 acre-feet and CCWD’s 2025 single-dry year value of 174,000 (Draft EIR, Section 3.15, Table 3.15-3: Water Consumption Estimate, Page 3.15-20). Accordingly, adequate water supplies would be available to serve the project from existing and planned supplies (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-21). Potential Effect Impact UTIL-3 The proposed project would not result in a determination by the wastewater treatment provider which serves or may serve the project that it does not have adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-21). Findings Less than significant impact. Facts in Support of Findings Impacts related to sufficient water supplies are limited to operational impacts. The proposed project would generate an estimated 23,344 gallons per day (0.024 million gallons per day [mgd]) (Draft EIR, Section 3.15, Table 3.15-4: Wastewater Generation Estimate, Page 3.15-21). This amount of wastewater represents less than 1 percent of the Central San’s treatment plant daily discharge limit of 54 mgd. Thus, no new or expanded wastewater treatment or conveyance facilities would be required and there would be adequate capacity to serve the proposed project’s projected demand in addition to the provider’s existing commitments. Furthermore, Central San provided comments to the applicant confirming it could serve the proposed project providing standard requirements for new service connections (e.g., payment of connection fees) (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-21).

Findings Less than significant impact. Facts in Support of Findings During construction, the proposed project would generate 4,480 cubic yards of construction and demolition waste. The three regional landfills have 136.2 million cubic yards of remaining capacity and, thus, can accommodate the construction solid waste generated by the proposed project. Construction and Demolition Debris Recycling practices would divert most, if not all, construction solid waste from landfills (Draft EIR, Section 3.15, Table 3.15-5: Construction and Demolition Solid Waste Generation Estimate, Page 3.15-22). During operation, the proposed project would generate 321 cubic yards of solid waste annually. The three regional landfills have 136.2 million cubic yards of remaining capacity and, thus, can accommodate the solid waste generated by the proposed project at operation (Draft EIR, Section 3.15, Table 3.15-6: Operational Solid Waste Generation Estimate, Page 3.15-23). Aluminum, glass, plastic, paper, cardboard, and organic waste are collected and diverted from the waste stream. As such, the values discussed above likely overstate the solid waste generation that would be expected to occur from the proposed project (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15- 23). Potential Effect Impact UTIL-5 The proposed project would comply with federal, State, and local statutes and regulations related to solid waste (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-23). Findings Less than significant impact. Facts in Support of Findings During construction, the proposed project would be required to comply with the County’s Ordinance Code Title 4 Division 418-2.028 related to solid waste reduction and recycling measures. These measures would ensure compliance with the Integrated Waste Management Act by ensuring project construction waste is transferred to facilities that can adequately recycle solid waste. During project operation, the proposed project would be required to comply with applicable State and local regulations related to solid waste such as the California Integrated Waste Management Act and Title 4 Chapter 418 of the Contra Costa County Ordinance Code. Adherence to the County Ordinance Code would ensure sufficient solid waste collection and transportation is available to the Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 51 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx project and would also ensure that disposal sites contain sufficient capacity through permit review and inspections and recycling programs are implemented in order to divert waste. As such, project operation would not impede the ability of the County to meet waste diversion requirements or cause the County to violate State and local statutes and regulations related to solid waste (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-24). Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in a less than significant cumulative impact related to utilities and service systems (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-25). Findings Less than significant impact. Facts in Support of Findings Water Cumulative projects are located within the CCWD service area and would create water supply demand. The CCWD 2015 UWMP determined that CCWD would be able to provide adequate water supplies to the County and cumulative projects area. The County would have adequate water supplies to serve the cumulative projects during normal and dry years. In addition, cumulative projects would be required to comply with provisions of the County Code and California Green Building Code related to water conservation. Therefore, cumulative impacts are less than significant. Moreover, the proposed project ’s incremental contribution to cumulative impacts would not be significant. The proposed project, in conjunction with identified cumulative projects in Contra Costa County, would result in a less than significant cumulative impact related to water supply and water supply facilities less than significant impact (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-24). Wastewater Central San provides wastewater collection and treatment services for contracted cities and residents and business in unincorporated County land. Central San considered the existing capacity and future demand for capacity to determine needed updates to wastewater and recycled water facilities. In the course of preparing the Comprehensive Wastewater Master Plan, Central San estimated wastewater generated from future development in the service area and forecast the needed facility upgrades. The forecast included treatment facility upgrades needed to accommodate growth in the County and maintain compliance with applicable regulatory standards for wastewater treatment and discharge. The Comprehensive Wastewater Master Plan determined that capacity exists to service the County and cumulative projects area demand with respect to wastewater treatment facilities. Therefore, cumulative impacts are less than significant. Moreover, the project’s incremental contribution to cumulative wastewater impacts would not be significant. The proposed project, in conjunction with identified cumulative projects in Contra Costa County would result in a less than significant cumulative impact related to wastewater generation and wastewater treatment facilities less than significant impact (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15- 25).

Cumulative projects predominantly consist of commercial and non-residential uses located in unincorporated Contra Costa County, the City of Walnut Creek, or the City of Pleasant Hill that generate volumes of stormwater. The proposed project may be required to construct improvements such that the storm drain line is adequate, which may include an expansion of this stormwater facility to ensure that adequate capacity is maintained. Therefore, cumulative impacts are less than significant. Moreover, the project’s incremental contribution to cumulative storm drainage impacts would not be significant. The proposed project, in conjunction with the construction of other projects, would not result in a significant cumulative impact related to stormwater generation and stormwater drainage facilities (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-25). Solid Waste Central Contra Costa County Solid Waste Authority (RecycleSmart) oversees regional waste diversion programs and contracts for the solid waste recycling collection services provided within this area of the County. Cumulative projects consist predominantly of residential uses and would generate solid waste that would increase demand on solid waste facilities to receive, process, and dispose solid waste. The three regional landfills that serve the County have a combined remaining capacity of 136.2 million cubic yards. The anticipated waste volume of cumulative projects development would be 321 cubic yards per year that represents less than 1 percent of the available capacity. Existing solid waste facilities provide sufficient capacity to serve cumulative development anticipated in the County. Therefore, cumulative impacts are less than significant. Moreover, the project’s incremental contribution to cumulative solid waste impacts would not be significant. The proposed project, in conjunction with identified cumulative projects, would result in a less than significant cumulative impact related to solid waste generation and landfill capacity (Draft EIR, Section 3.15, Utilities and Service Systems, Page 3.15-25). 1.5.15 - Wildfire Potential Effect Impact WILD-1 The proposed project would not substantially impair an adopted emergency response plan or emergency evacuation plan (Draft EIR, Section 3.16, Wildfire, Page 3.16-11). Findings Less than significant impact. Facts in Support of Findings The proposed project would comply with the County EOP, ensuring efficient response to emergency incidents associated with emergencies affecting the County. Furthermore, blockage of an evacuation route would not occur during project construction because the proposed project would not result in road closures to either Oak Road or Jones Road, the most likely evacuation routes from the project site. Additionally, the project site is not located in a “Fire Hazard Severity Zone” in a State Responsibility Area (SRA) or a “Very High Fire Hazard Severity Zone” in a local, State, or federal responsibility area.

The proposed project would not create a permanent increase in population unaccounted for in the General Plan that could lead to overwhelming calls for emergency services. In addition, the proposed project would be designed in accordance with the County’s standards to accommodate emergency vehicle access by providing two points of access to the project site and internal roadways that would be available to emergency vehicles. Furthermore, blockage of an evacuation route would not occur during project operation because the proposed project would not result in road closures to Oak Road or Jones Road, the most likely evacuation routes from the project site. With adherence to General Plan Policy 7-64, and Implementation Measures 7-at and 7-au, which require development fees, fire agency project review, and creation of a safe environment in case of substantial disaster, the proposed project would not conflict with the County EOP or General Plan (Draft EIR, Section 3.16, Wildfire, Page 3.16- 12). Potential Effect Impact WILD-2 The proposed project would not due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire (Draft EIR, Section 3.16, Wildfire, Page 3.16-12). Findings Less than significant impact. Facts in Support of Findings Impacts related to exposure of project occupants to pollutants concentrations from wildfire are limited to operational impacts. The project site is mostly surrounded by urbanized uses on relatively flat areas lacking in woodlands or vegetation that could provide fuel load for wildfire, or steep slopes that could cause fire to spread more rapidly. The project site is surrounded by other features that provide fuel breaks in the event of a fire, such as I-680, the Contra Costa Canal, Oak Road, and Jones Road. The closest open space area (Briones Regional Park) is located approximately 3 miles west of the project site (Draft EIR, Section 3.16, Wildfire, Page 3.16-12). The project site is not located in an SRA or Local Responsibility Area (LRA) Fire Hazard Severity Zone. The nearest Fire Hazard Severity Zone is located approximately 2 miles west of the project site (Briones Regional Park) and is designated as a High Fire Hazard Severity Zone. The BAAQMD monitors the Bay Area’s air quality at a number of stations, and the closest station to the project site is located in the City of Concord, approximately 4 miles to the northeast. The average wind speed at this station varied from month to month and ranged from 7 to 16 mph in 2020. Given that the project site is not located on or near steep terrain surrounded by natural vegetation, is mostly surrounded by urban uses, and does not consistently experience high winds, the project site would not be prone to wildfires. Compliance with applicable State and local plans and regulations would decrease the risk of impacts related to wildland fire hazards. Specifically, General Plan policies incorporate requirements for fire- Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 54 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx safe construction into the land use planning and approval process and ensure special fire protection for high-risk land uses and structures. The County also implements an EOP, which addresses response to emergency incidents affecting the County. Furthermore, the proposed project would be adequately served in terms of fire protection services by the CCCFPD. Finally, the proposed project would be required to comply with the California Fire Code regarding emergency access and types of building materials (Draft EIR, Section 3.16, Wildfire, Page 3.16-13). Potential Effect Impact WILD-3 The proposed project would not require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment (Draft EIR, Section 3.16, Wildfire, Page 3.16-13). Findings Less than significant impact. Facts in Support of Findings Impacts related to installation or maintenance of infrastructure that may exacerbate fire risk are limited to operational impacts. The proposed project would include adequate emergency access via existing roads at two access points. The project site is in an urban area surrounded by existing roadways. The proposed project would not require the installation of firebreaks because it is in an urban area surrounded by existing development with little natural vegetation. The proposed project would not require emergency water sources because potable water is currently provided by the CCWD, which has adequate water supplies available to serve the project and future development during normal, dry, and multiple dry years. New electrical power and natural gas lines on and connecting to the project site would be installed underground, minimizing potential ignition and related fire risk above ground, at the project site according to the CBC, Uniform Fire Code, and Contra Costa County General Plan Implementation Measure 7-au. Finally, off-site improvements, including frontage sidewalks, driveway curbs, and gutter improvements, would not exacerbate fire risk (Draft EIR, Section 3.16, Wildfire, Page 3.16-14). Potential Effect Impact WILD-4 The proposed project would not expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes (Draft EIR, Section 3.16, Wildfire, Page 3.16-14). Findings Less than significant impact. Facts in Support of Findings Impacts related to post-fire slope instability are limited to operational impacts. The project site is not located on or near steep slopes susceptible to landslides or downstream flooding.

Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would result in a less than significant cumulative impact related to wildfire (Draft EIR, Section 3.16, Wildfire, Page 3.16-15). Findings Less than significant impact. Facts in Support of Findings A combination of federal, State, and local regulations limit or minimize the potential for exposure to wildfires by reducing the amount of development in wildland urban interface areas, ensuring new development is developed according to the CBC and Uniform Fire Code, and incorporating requirements for fire-safe construction into the land use planning. Cumulative projects consist predominantly of residential and commercial development. Only one of the projects would be located in designated and High or Very High Fire Hazard Zones, and an additional project is located on the edge of a High Fire Hazard Zone. However, these projects would be in areas that are already developed and do not contain significant levels of dry fuel susceptible to ignition or significantly high average wind speeds. The cumulative projects would result in predominantly infill development and would not significantly increase emergency services beyond the existing service area. Furthermore, all cumulative project construction would adhere to the County Building Codes that are designed to minimize the potential for uncontrolled fires. Adherence to County Building Codes would ensure that California Fire Code standards ,such as automatic sprinkler systems and management of fuel loads in response to annual inspection by the Fire Department, are included in development. Once cumulative development is proposed, the County assesses the needs for fire protection services and informs efforts to improve or expand needed facilities. All development would, however, comply with emergency access requirements, such as two emergency vehicle access points, as a condition of construction. Furthermore, the cumulative projects would not result in permanent road closures impede an established emergency or evacuation access route, such as I-680, or interfere with emergency response requirements, such as fire protection response time standards established by the General Plan. As such, there would be a less than significant cumulative impact associated with wildfire hazards and emergency/evacuation response (Draft EIR, Section 3.16, Wildfire, Page 3.16- 15). The proposed project’s incremental contribution to cumulative wildfire hazard impacts would not be significant. As previously discussed, the proposed project is located in an already developed areas and would involve infill development and redevelopment. As a result, the proposed project would not contribute to or exacerbate the degree of wildland fire hazard, including secondary hazards. For this reason, and those discussed in Impacts WILD-1 through WILD-4, the proposed project’s contribution to cumulative impacts would also be less than significant.

The potentially significant impacts, and the mitigation measures that will reduce them to a less than significant level, are as follows: 1.6.1 - Aesthetics, Light, and Glare Potential Effect Impact AES-4 The proposed project could create a substantial new source of light or glare which would adversely affect day or nighttime views in the area (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-9). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-12). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM AES-4 Prepare Final Lighting Plan At least 30 days prior to applying for a building permit, the applicant shall submit for review and approval by the Department of Conservation and Development, Community Development Division a Final Lighting Plan. Exterior lighting must be directed downward and away from adjacent properties and public/private right-of-way to prevent glare or excessive light spillover. Facts in Support of Findings The proposed project would result in 125 townhouse condominiums with associated windows, as well as exterior lighting and signage. The site is surrounded by residential uses, as well as Oak Road and Jones Road, all of which contribute to the existing daytime glare and nighttime lighting of the area. The proposed project would result in the development of residential uses that would include nighttime security lighting consistent with surrounding uses. Potential sources of light associated with the proposed project would consist of typical sources of lighting associated with a residential development and from vehicles traveling to and from the project site. Exterior lighting would be located around and within the project site. Lampposts would be evenly dispersed within the project site, with safety lighting, as needed throughout the site. MM AES-4 requires exterior lighting be directed downward and away from adjacent properties and public/private right-of-way to prevent glare (Draft EIR, Section 3.1, Aesthetics, Light, and Glare, Page 3.1-12–13). The County finds that MM AES-4 is feasible, is adopted, and will further reduce impacts associated with aesthetics, light, and glare. Accordingly, the County finds that, pursuant to Public Resources Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 57 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Aesthetics, Light, and Glare would be less than significant with mitigation incorporated. 1.6.2 - Air Quality Potential Effect Impact AIR-2 The proposed project could result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or State ambient air quality standard (Draft EIR, Section 3.2, Air Quality, Page 3.2-43). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.2, Air Quality, Page 3.2-47). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM AIR-2 Apply Construction Best Management Practices The contractor shall implement the following enhanced Best Management Practices (BMPs): 1. During site preparation and grading, all exposed surfaces shall be watered at a frequency adequate to maintain minimum soil moisture of 12 percent. Moisture content can be verified by lab samples or moisture probe. 2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered. 3. All visible mud or dirt tracked out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. 4. All vehicle speeds on unpaved roads shall be limited to 15 miles per hour (mph). 5. All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible. Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. 6. All construction equipment shall be maintained and properly tuned in accordance with manufacturer’s specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation. 7.

All excavation, grading, and/or demolition activities shall be suspended when average wind speeds exceed 20 mph. 9. Wind breaks (e.g., trees, fences) shall be installed on the windward side(s) of actively disturbed areas of construction. Wind breaks should have at maximum 50 percent air porosity. 10. Vegetative ground cover (e.g., fast-germinating native grass seed) shall be planted in disturbed areas as soon as possible and watered appropriately until vegetation is established. 11. The simultaneous occurrence of excavation, grading, and ground-disturbing construction activities on the same area at any one time shall be limited. Activities shall be phased to reduce the amount of disturbed surfaces at any one time. 12. All trucks and equipment, including their tires, shall be washed off prior to leaving the site. 13. Site accesses to a distance of 100 feet from the paved road shall be treated with a 6-to-12-inch compacted layer of wood chips, mulch, or gravel. 14. Sandbags or other erosion control measures shall be installed to prevent silt runoff to public roadways from sites with a slope greater than 1 percent. 15. Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 2 minutes. Clear signage shall be provided for construction workers at all access points. Facts in Support of Findings Predicted construction period emissions would not exceed the Bay Area Air Quality Management District (BAAQMD) significance thresholds. Construction activities, particularly during site preparation and grading, would temporarily generate fugitive dust in the form of PM10 and PM2.5. Sources of fugitive dust would include disturbed soils at the construction site and trucks carrying uncovered loads of soils. Unless properly controlled, vehicles leaving the site would deposit mud on local streets, which could be an additional source of airborne dust after it dries. The BAAQMD CEQA Air Quality Guidelines consider these impacts to be less than significant if BMPs are implemented to reduce these emissions. For example, these BMPs would reduce fugitive dust, in part, by requiring all exposed surfaces to be watered at a frequency adequate to maintain minimum soil moisture of 12 percent, which would reduce the amount of dust on-site. Additionally, dust would be contained and reduced by requiring all haul trucks transporting soil, sand, or other loose material off-site to be covered. MM AIR-2 would require the implementation of BAAQMD-recommended BMPs to reduce fugitive dust (PM10 and PM2.5) (Draft EIR, Section 3.2, Air Quality, Page 3.2-43–46). Operational air emissions from the proposed project would be generated primarily from autos driven by future residents and guests. Evaporative emissions (e.g., reactive organic gases [ROG]) from architectural coatings and maintenance products (classified as consumer products) are typical emissions from residential projects. Operational period emissions would not exceed the BAAQMD significance thresholds, and emissions from the proposed project are anticipated to be less than the prior school use operation for all analyzed pollutants except ROG. (Draft EIR, Table 3.2-11: Operational Emissions, Page 3.2-46). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 59 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx The CO emissions from traffic generated by the project are a concern at the local level. Congested intersections can result in high, localized concentrations of carbon monoxide (CO). The proposed project is estimated to generate a total of 93 AM peak-hour vehicle trips and 124 PM peak-hour vehicle trips. Conservatively assuming that all peak-hour vehicle trips generated by the proposed project would travel through the intersection of Oak Road and Treat Boulevard, the Existing Plus Project traffic volumes would be 6,109 AM peak-hour trips and 5,266 PM peak-hour trips. Therefore, the proposed project would not cause any intersections near the proposed project to experience traffic volumes of 44,000 vehicles per hour. Furthermore, the adjacent roadways are not located in an area where vertical or horizontal atmospheric mixing is substantially limited. Based on the above criteria, the proposed project would not cause an exceedance of the CO screening criteria (Draft EIR, Section 3.2, Air Quality, Page 3.2-47). The County finds that MM AIR-2 is feasible, is adopted, and will further reduce impacts associated with Air Quality. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Air Quality would be less than significant with mitigation incorporated. Potential Effect Impact AIR-3 The proposed project could expose sensitive receptors to substantial pollutant concentrations. (Draft EIR, Section 3.2, Air Quality, Page 3.2-48). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.2, Air Quality, Page 3.2-52). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures: MM AIR-3 Selection of equipment during construction to minimize diesel particulate matter (DPM) emissions. The project shall implement the following: 1. Prior to the issuance of grading or construction permits, the applicant shall provide the Department of Conservation and Development, Community Development Division (CDD) with documentation to the satisfaction of CDD that all diesel-powered off-road equipment, larger than 25 horsepower, operating on the site for more than two days continuously, at a minimum, meet United States Environmental Protection Agency (EPA) emissions standards for Tier 4 Interim engines. Where Tier 4 equipment is not available, exceptions could be made for equipment meeting Tier 2 or Tier 3 standards that include California Air Resources Board (ARB)-certified Level 3 Diesel Particulate Filters or equivalent.

Minimize diesel generator use by providing line power to the site during early construction phases. 3. Avoid staging construction equipment near residences (i.e., within 200 feet of homes). Facts in Support of Findings As a residential project, the proposed project itself would be considered a sensitive receptor once operational. The project site is surrounded by existing residences to the south, east, and north of the project site. The closest off-site air pollution sensitive receptors in the vicinity of the project site include multi-family apartments north and south of the project site as well as single-family residences east of the project site across Oak Road. Structures to be demolished sometimes contain ACM. All ACM found on-site must be removed prior to demolition or renovation activity in accordance with BAAQMD Regulation 11, Rule 2, including specific requirements for surveying, notification, removal, and disposal of ACMs. Therefore, projects that comply with BAAQMD Regulation 11, Rule 2 would ensure that ACM would be removed and disposed of appropriately and safely. By complying with BAAQMD Regulation 11, Rule 2, thereby minimizing the release of airborne asbestos emissions during demolition. Furthermore, USGS map indicates that there are several locations within the County that are likely to contain naturally occurring asbestos; however, none of these sites are located within a 1-mile vicinity of the project site. Therefore, the proposed project would not expose sensitive receptors to naturally occurring asbestos during project construction (Draft EIR, Section 3.2, Air Quality, Page 3.2-49). Activities associated with earthmoving activities and construction would generate short-term emissions of fugitive dust resulting in increased dust fall and locally elevated levels of PM10 and PM2.5 downwind of construction activity. Construction dust has the potential for creating a nuisance at nearby properties. As addressed under Impact AIR-2, MM AIR-2 is included to ensure that the BAAQMD BMPs would be implemented to reduce fugitive dust emissions from construction activities (Draft EIR, Section 3.2, Air Quality, Page 3.2-49). During construction, the proposed project would result in the emissions of toxic air contaminants (TACs ) that could potentially impact nearby sensitive receptors. On-site diesel particulate matter (DPM) emissions would be generated by off-road construction equipment and the off-site DPM emissions would be generated by trips associated with the hauling of material, vendor trips, and worker vehicle traffic. Unmitigated incremental increase in cancer risk from construction was 16.3 per million at the maximally exposed individual (MEI). The maximum annual PM2.5 concentration from construction was 0.45 micrograms per cubic meter (μg/m3). Both exceed their respective BAAQMD single-source thresholds of greater than 10 in a million and greater than 0.3 μg/m3 for PM2.5 concentration. MM AIR-3 would reduce the generation of DPM during project construction to reduce health risk impacts to less than significant. With the incorporation of MMs AIR-2 and AIR-3, the incremental cancer risk and PM2.5 concentration would not exceed the appropriate BAAQMD’s single-source thresholds. Both Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 61 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx the unmitigated and mitigated non-cancer hazards from construction activities would be below the BAAQMD’s single-source significance threshold of 1.0 (Draft EIR, Section 3.2, Air Quality, Page 3.2- 50–51). The incorporation of MM AIR-3 would not reduce the annual PM2.5 concentration to below the BAAQMD’s community threshold of 0.8 μg/m3, ultimately resulting in a community annual PM2.5 concentration of 1.17 μg/m3. Nonetheless, as shown in Table 3.2-12, the proposed project’s contribution to that exceedance in community annual PM2.5 concentration constitutes an estimated 0.19 μg/m3. As such, without implementation of the proposed project, the area would otherwise experience an annual PM2.5 concentration of 0.98 μg/m3, which is currently above the BAAQMD’s threshold of 0.8 μg/m3. Therefore, because the proposed project would be implementing mitigation sufficient to reduce the proposed project’s health risk impacts to below the BAAQMD’s single-source thresholds and the annual PM2.5 concentration would exceed BAAQMD thresholds without implementation of the proposed project, the proposed project would not result in a significant impact or be cumulatively considerable (Draft EIR, Section 3.2, Air Quality, Page 3.2-51). The proposed project would not generate sufficient carbon monoxide (CO) emissions during project operation to substantiate the creation of a CO hotspot. Therefore, this impact would be less than significant with regard to exposing sensitive receptors to substantial concentrations of CO emissions. The County finds that MM AIR-3 is feasible, is adopted, and will further reduce impacts associated with Air Quality. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Air Quality would be less than significant with mitigation incorporated. Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, would not result in significant cumulative air quality or health impacts (Draft EIR, Section 3.2, Air Quality, Page 3.2-54). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.2, Air Quality, Page 3.2-54). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental cumulative effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures Implement MM AIR-2 and MM AIR-3 above. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 62 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Facts in Support of Findings The determination of cumulative air quality impacts for construction and operational emissions is based on whether the proposed project would result in regional emissions that exceed BAAQMD regional thresholds of significance for construction and operations on a project level. Projects that generate emissions below the BAAQMD significance thresholds would be considered consistent with regional air quality planning efforts would not generate cumulatively significant emissions. As discussed in Impact AIR-2, with the incorporation of MM AIR-2, the proposed project would result in construction and operational emissions which are less than the respective BAAQMD significance thresholds and would therefore not have a cumulatively considerable contribution to a cumulative impact. The proposed project would therefore result in less than significant cumulative air quality impacts (Draft EIR, Section 3.2, Air Quality, Page 3.2-54). Regarding impacts to sensitive receptors, the DPM emissions from construction of the proposed project would result in less than significant health impacts after implementation of MM AIR-3 and would not combine with emissions from other cumulative projects to the extent that a significant cumulative impact would occur. In addition, the operational DPM emissions during operation of the proposed project would not result in significant health impacts and would constitute the greatest level of development. Given that the proposed project would be required to implement mitigation that is likely to result in decreased DPM emissions from what is disclosed in this analysis, the combined operation of the proposed project would not result in exposing nearby sensitive receptors to substantial amounts of pollutants. As discussed in Chapter 3, Environmental Impact Analysis, foreseeable future development projects in the area would not place new sensitive receptors near the proposed project that would be exposed to substantial amounts of pollutants. Therefore, the cumulative impact associated with construction and operation of the proposed project would be less than significant. Odor impacts that would be associated with the proposed project would principally be limited to the combustion of transportation fuels during construction and operation. The impact would be less than significant during project construction and operation would be intermittent and spatially dispersed. Therefore, cumulative odor impacts would be less than significant. 1.6.3 - Biological Resources Potential Effect Impact BIO-1 The proposed project could have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Wildlife or United States Fish and Wildlife Service.

A qualified wildlife Biologist shall conduct surveys for special-status bats during the appropriate time of day to maximize detectability to determine whether bat species are roosting near the work area no more than 5 days prior to beginning ground disturbance and/or construction. Survey methodology may include visual surveys of bats (e.g., observation of bats during foraging period), inspection for suitable habitat, bat sign (e.g., guano), or use of ultrasonic detectors (Anabat, etc.) 2. Visual surveys will include trees within 100 feet of project construction activities. Prior to building demolition, the applicants for development on any project parcel shall ensure that a qualified Biologist (i.e., one familiar with the identification of bats and signs of bats) survey buildings proposed for demolition for the presence of roosting bats or evidence of bats. If no roosting bats or evidence of bats are found in the structure, demolition may proceed. If the Biologist determines bats are present, the Biologist shall exclude the bats from suitable spaces by installing one-way exclusion devices. After the bats vacate the space, the Biologist shall close off the space to prevent recolonization. Building demolition shall only commence after the Biologist verifies 7 to 10 days later that the exclusion methods have successfully prevented bats from returning. To avoid impacts on non-volant (i.e., nonflying) bats, the Biologist shall only conduct bat exclusion and eviction from September 1 through March 31. Exclusion efforts shall be restricted during periods of sensitive activity. MM BIO-1b Migratory and Nesting Birds 1. If the project requires vegetation to be removed during the nesting season (February 1–August 31), pre-construction surveys shall be conducted 5 days prior to vegetation removal to determine whether or not active nests are present. 2. If an active nest is located during pre-construction surveys, a qualified Biologist shall determine an appropriately-sized avoidance buffer based on the species and anticipated disturbance level. Based on input from the Biologist, the project applicant will delineate the avoidance buffer using Environmentally Sensitive Area fencing, pin flags, and or yellow caution tape. The buffer zone will be maintained around the active nest site(s) until the young have fledged and are foraging independently. No construction activities shall be allowed within the avoidance buffer(s). 3. The qualified Biologist shall periodically monitor the active nest during construction activities to prevent any potential impacts that may result from the construction of the proposed project, until the young have fledged.

Suitable habitat requirements for special-status plant species include chaparral, riparian, alkaline, or serpentine soils; these features are absent from the project site. Therefore, no special-status plant species have the potential to occur within the project site and no special-status plant species would be impacted by project construction. Five special-status wildlife species (pallid bat, Townsend’s big-eared bat, big free-tailed bat, hoary bat, and white-tailed kite) as well as other birds protected under the MBTA and Fish and Game Code have potential to occur on the project site and, thus, have the potential to be impacted by project construction. Potential direct and indirect impacts could occur to roosting bats during project construction due to removal of potential roosting habitat, these impacts would be considered significant under CEQA. Implementation of MM BIO-1a, which requires the project applicant to conduct a pre-construction survey and to implement further avoidance and minimization measures (if bats are present), would reduce potential impacts to roosting bats Construction activities that occur during the avian nesting season (generally February 1 to August 31) could disturb nesting sites for bird species including special-status species such as the white- tailed kite as well as birds protected under the MBTA and the California Fish and Game Code. Implementation of MM BIO-1b, which requires the project applicant to conduct a pre-construction survey and to implement further avoidance and minimization measures (if necessary), would reduce potential impacts to nesting birds to a less than significant level under CEQA. The project site is surrounded by residential and commercial developments and is situated in an urban landscape with high amounts of traffic from local business operations, which create a baseline of ambient noise. The proposed project would increase traffic on local roadways and would introduce stationary noise sources through the operation of new a residential facility; however, noise emitted from the operation of the project would be within established standards and would not result in a significant increase in the ambient environment. Therefore, project implementation would not constitute a significant impact to wildlife species from operational noise including traffic noise (Draft EIR, Section 3.3, Biological Resources, Page 3.3-21). The County finds that MM BIO-1a and MM BIO-1b are feasible, are adopted, and will further reduce impacts associated with Biological Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Biological Resources would be less than significant with mitigation incorporated.

Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.3, Biological Resources, Page 3.3-23 – 24). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures: MM BIO-5a Prepare and Implement a Tree Replacement Plan A Tree Replacement Plan shall be submitted and approved by Department of Conservation and Development, Community Development Division (CDD) prior to the removal of trees, prior to issuance of a demolition or grading permit, whichever occurs first. The Tree Replacement Plan shall designate the approximate location, number, and sizes of trees to be planted. Trees shall be planted prior to requesting a final inspection of the building permit. MM BIO-5b Implement Tree Preservation Guidelines During Construction Tree protection guidelines shall be implemented during construction throughout the clearing, grading, and construction phases as outlined on pages 12 and 13 in the arborist report prepared by HortScience dated January 4, 2021. Facts in Support of Findings The Tree Report provides an inventory and preliminary evaluation of all trees over 6 inches in diameter within the project site. Trees that were surveyed were numbered, tagged, identified, measured, and evaluated. According to the Tree Report, a total of 74 trees would be removed as part of project implementation, one tree would be relocated, and six off-site trees would be preserved. Of the trees proposed for removal, 73 trees are considered protected due to their size, the remaining eight trees do not qualify as protected based on the Tree Protection and Preservation Ordinance. If not properly protected, the trees proposed for preservation could also be subject to injury or inadequate maintenance during construction, which represents a potentially significant impact. The response of individual trees would depend on the amount of excavation and grading, the care with which demolition is undertaken, and the construction methods. As the construction of the proposed project requires the removal of trees subject to the Contra Costa County Tree Protection and Preservation Ordinance, the applicant would be required to prepare and implement a tree replacement plan. In addition, remaining trees that are proposed for preservation on the project site would be preserved through the implementation of the tree preservations guidelines identified and outlined in the Tree Report and in the Contra Costa County Tree Protection and Preservation Ordinance.

Impacts related to the consistency of the project with local biological resources policies and ordinances are limited to construction impacts because the project applicant would be required to monitor, protect, and maintain preserved trees (Draft EIR, Section 3.3, Biological Resources, Page 3.3-23). The County finds that MM BIO-5a and MM BIO-5b are feasible, are adopted, and will further reduce impacts associated with Biological Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Biological Resources would be less than significant with mitigation incorporated. 1.6.4 - Cultural Resources and Tribal Cultural Resources Potential Effect Impact CUL-1 The proposed project could cause a substantial adverse change in the significance of a historical resource pursuant to Section 15064.5 (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-20).

(State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures: MM CUL-1 Archaeological Spot-Monitoring and Halt of Construction Upon Encountering Historical or Archaeological Materials An Archaeologist who meets the Secretary of the Interior ’s Professional Qualification Standards for archaeology should inspect the site once grubbing and clearing are complete and prior to any grading or trenching into previously undisturbed soils. This will be followed by regular periodic or “spot-check” archaeological monitoring as determined by the Archaeologist. If the Archaeologist believes that a reduction in monitoring activities is prudent, then a letter report detailing the rationale for making such a reduction and summarizing the monitoring results shall be provided to the Department of Conservation and Development, Community Development Division (CDD) for concurrence.

The applicant for the proposed project shall include a standard inadvertent discovery clause in every construction contract to inform contractors of this requirement. Potentially significant cultural resources consist of but are not limited to stone, bone, glass, ceramics, fossils, wood or shell artifacts, or features including hearths, structural remains, or historic dumpsites. The Archaeologist shall make recommendations concerning appropriate measures that will be implemented to protect the resource, including but not limited to excavation and evaluation of the finds in accordance with Section 15064.5 of the CEQA Guidelines. Any previously undiscovered resources found during construction within the project site shall be recorded on appropriate California Department of Parks and Recreation (DPR) 523 forms and will be submitted to the Department of Conservation and Development, Community Development Division (CDD), the Northwest Information Center (NWIC), and the California Office of Historic Preservation (OHP), as required. Facts in Support of Findings Archival research identified a total of 15 previously recorded built environment resources within a 0.5-mile radius of the project site. Of these, 14 are historic-age buildings or structures located on the project site (single-family residences, industrial property, unidentified property) that have been previously found ineligible for listing in the National Register of Historic Places (NRHP) and/or California Register of Historical Resources (CRHR) and they do not qualify as historical resources. No previously recorded historical resources are present within or in close proximity to (within 50 feet of) the project site. The pedestrian survey identified the Palmer School, established in 1939. A review of aerial photographs indicated that some existing on-site buildings and structures date to 1965 or earlier, indicting they are 55 years old or more and above the 50 years age threshold for consideration for listing in the California Register. There are 14 historic-age buildings or structures (single-family residences, industrial property, unidentified property) located on the project site that have been previously found ineligible for listing in the NRHP and/or CRHR, and they do not qualify as historical resources. While unlikely, subsurface construction activities always have the potential to damage or destroy previously undiscovered historic resources such as wood, stone, foundations, and other structural remains; debris-filled wells or privies; and deposits of wood, glass, ceramic, and other refuse, if encountered. This would represent a potentially significant impact related to historic resources. Implementation of MM CUL-1, which requires an inspection and spot-monitoring by a qualified Archaeologist after clearing and grubbing are complete, but before any digging or trenching begin, would reduce potential impacts to historic resources that may be discovered during project construction, including off-site improvements (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-20).

(State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM CUL-1 above. Facts in Support of Findings Records search results indicate that 13 cultural resources have been mapped within a 0.5-mile radius of the project site. One of these is a prehistoric archaeological site and 12 are built environment resources. None of these resources are within or in close proximity to the project site. No archaeological resources have been recorded within the project site. However, the close proximity to the historical alignment of Walnut Creek, the relatively flat topography within the project site, and the occurrence of a nearby prehistoric archaeological site creates a potential for undiscovered prehistoric resources to occur within the project site. This represents a potentially significant impact related to archaeological resources. Implementation of MM CUL-1 requires inspection and spot-monitoring by a qualified Archaeologist after clearing and grubbing are complete but before any excavation or trenching begin, would reduce potential impacts to archaeological resources that may be discovered during project construction.

Mitigation Measures: MM CUL-3 Stop Construction Upon Encountering Human Remains In the event of the accidental discovery or recognition of any human remains, CEQA Guidelines Section 15064.5, Health and Safety Code Section 7050.5, and Public Resources Code Sections 5097.94 and Section 5097.98 shall be followed. If during the course of project construction, there is accidental discovery or recognition of any human remains, the following steps shall be taken: 1. There shall be no further excavation or disturbance within 100 feet of the remains until the County Coroner is contacted to determine whether the remains are Native American and if an investigation of the cause of death is required. If the Coroner determines the remains to be Native American, the Coroner shall contact the Native American Heritage Commission (NAHC) within 24 hours, and the NAHC shall identify the person or persons it believes to be the Most Likely Descendant (MLD) of the deceased Native American. The MLD may make recommendations to the landowner or the person responsible for the excavation work within 48 hours, for means of treating or disposing of, with appropriate dignity, the human remains and any associated grave goods as provided in Public Resources Code Section 5097.98. 2. Where the following conditions occur, the landowner or his or her authorized representative shall rebury the Native American human remains and associated grave goods with appropriate dignity either in accordance with the Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 70 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx recommendations of the MLD or on the project site in a location not subject to further subsurface disturbance: • The NAHC is unable to identify an MLD or the MLD failed to make a recommendation within 48 hours after being notified by the NAHC. • The descendant identified fails to make a recommendation. • The landowner or his authorized representative rejects the recommendation of the descendant, and mediation by the NAHC fails to provide measures acceptable to the landowner. Additionally, California Public Resources Code Section 15064.5 requires the following relative to Native American Remains: When an initial study identifies the existence of, or the probable likelihood of, Native American Remains within a project, a lead agency shall work with the appropriate Native Americans as identified by the NAHC as provided in Public Resources Code Section 5097.98. The applicant may develop a plan for treating or disposing of, with appropriate dignity, the human remains and any items associated with Native American Burials with the appropriate Native Americans as identified by the NAHC. Facts in Support of Findings No human remains or cemeteries are known to exist within or near the project site. However, there is always the possibility that subsurface construction activities associated with the proposed project, such as trenching and grading, could potentially damage or destroy previously undiscovered human remains. This represents a potentially significant impact related to human remains. However, in the unlikely event human remains are discovered, both within the project site and within the areas proposed for the off-site improvements, implementation of MM CUL-3 would require that work be halted, and the County Coroner be called to make a determination as to the nature of the remains and to confirm next steps regarding contacting the NAHC and appropriate tribal representatives. Impacts related to a project’s potential to disturb human remains are limited to construction impacts. No respective direct or indirect operational impacts related to human remains would occur (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-22–23). The County finds that MM CUL-3 is feasible, is adopted, and will further reduce impacts associated with Cultural Resources and Tribal Cultural Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Cultural Resources and Tribal Cultural Resources would be less than significant with mitigation incorporated.

Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-24). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM CUL-1 and MM CUL-3 above. Facts in Support of Findings A review of the CRHR, local registers of historic resources, a records search conducted at the NWIC, and an NAHC Sacred Lands File (SLF) search failed to identify any listed Tribal Cultural Resources (TCRs) that may be adversely affected by the proposed project. Moreover, no tribe requested consultation within the 30-day period established by AB 52. However, if a potential resource is identified, construction would be required to stop until appropriate identification and treatment measures are implemented (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-24). Impacts related to a project’s potential to cause a substantial adverse change in the significance of a State listed or eligible TCR are limited to construction impacts. No respective operational impacts would occur (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-24). The County finds that MM CUL-1 and MM CUL-3 are feasible, are adopted, and will further reduce impacts associated with Cultural Resources and Tribal Cultural Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR.

(Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-25). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-25). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM CUL-1 and MM CUL-3 above. Facts in Support of Findings On August 13, 2020, ESA contacted the NAHC to determine whether any sacred sites are listed on its SLF for the project area. A response was received on August 18, 2020, and indicated that the SLF results failed to indicate the presence of Native American cultural resources in the immediate project area. The NAHC included a list of eight tribal representatives available for consultation. To ensure that all Native American knowledge and concerns over potential TCRs that may be affected by the proposed project are addressed, a letter containing project information and requesting any additional information was sent to each tribal representative on May 11, 2021. On March 9, 2021, the County notified the Wilton Rancheria pursuant to Public Resources Code Section 21080.3.1 that the proposed project may be within a geographic area in which the tribe may be traditionally and culturally affiliated. On March 11, 2021, the Wilton Rancheria responded that it has no concerns regarding the proposed project. However, if a potential resource is identified, construction would be required to stop until appropriate identification and treatment measures are implemented. Therefore, direct and indirect impacts related to TCRs would be less than significant with implementation MM CUL-1 and MM CUL-3. Impacts related to a project’s potential to cause a substantial adverse change in the significance of a State listed or eligible TCR are limited to construction impacts. No operational impacts would occur (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-25). The County finds that MM CUL-1 and MM CUL-3 are feasible, are adopted, and will further reduce impacts associated with Cultural Resources and Tribal Cultural Resources. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Cultural Resources and Tribal Cultural Resources would be less than significant with mitigation incorporated.

(Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-25). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-25). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM CUL-1 and MM CUL-3 above. Facts in Support of Findings The geographic scope of the cumulative cultural resources analysis is the project vicinity. Cultural resource impacts tend to be localized, because the integrity of any given resource depends on what occurs only in the immediate vicinity around that resource, such as disruption of soils; therefore, in addition to the project site itself, the area near the project site would be the area most affected by project activities (generally within a 0.5-mile radius). Construction activities associated with development projects in the project vicinity may have the potential to encounter undiscovered cultural resources. These projects would be required to mitigate for impacts through compliance with applicable federal and State laws governing cultural resources. Although there is the possibility that previously undiscovered resources could be encountered by subsurface earthwork activities associated with the cumulative projects, the implementation of construction mitigation measures would ensure that undiscovered cultural resources are not adversely affected by cumulative project-related construction activities, which would prevent the destruction or degradation of potentially significant cultural resources (Draft EIR, Section 3.4, Cultural Resources and Tribal Cultural Resources, Page 3.4-26). Therefore, cumulative impacts would be less than significant. Additionally, the proposed project’s contribution to these less than significant impacts would not be cumulatively considerable for the reasons details in Impact CUL-1 though CUL-5.

(State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures: MM GEO-1a Conduct Design-level Geotechnical Exploration At least 60 days prior to recording the final Subdivision Map or requesting issuance of construction permits or installation of utility improvements, the applicant shall submit a design-level Geotechnical Exploration Report for the proposed project based on adequate subsurface exploration, laboratory testing, and engineering analysis. The scope of the Geotechnical Exploration Report shall address the following potential hazards: (i) grading, including removal of existing undocumented fill that is deemed to be unsuitable for use in engineered fills, preparation to receive fill, compaction standards for fill, etc., (ii) consolidation settlement, (iii) analysis of liquefaction potential, including estimating total settlement and differential settlement, and surface manifestation of liquefaction, (iv) foundation design, (v) measures to protect improvements from the relatively shallow water table, (vi) laboratory testing to evaluate the expansive and corrosion potential soils and measures designed to protect improvements that are in contact with the ground from these hazards, including the building foundation, parking garage slabs, flatwork, pavement, and utilities, (vii) exploration, testing, and engineering analysis aimed at providing recommendations pertaining to foundation design, including foundation retaining walls, and pavement design, (viii) evaluation of the drainage design, including the proposed bioretention facilities and their effect on planned improvements, (ix) address temporary shoring and support of excavations, (x) provide updated California Building Standards Code (CBC) seismic parameters, and (xi) outline the recommended geotechnical monitoring, commencing with clearing Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 75 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx and demolition, extending through final grading, installation of drainage improvements, and including the monitoring of foundation-related work. MM GEO-1b Conduct Geotechnical Observation and Testing Services During Construction The design-level geotechnical report required by Mitigation Measure GEO-1a routinely includes recommended geotechnical observation and testing services during construction. These services are essential to the success of the proposed project. They allow the Geotechnical Engineer to (i) ensure geotechnical recommendations for the proposed project are properly interpreted and implemented by contractors, (ii) allow the Geotechnical Engineer to view exposed conditions during construction to ensure that field conditions match those that were the basis of the design recommendations in the approved report, and (iii) provide the opportunity for field modifications of geotechnical recommendations (with Department of Conservation and Development, Community Development Division approval), based on exposed conditions. The monitoring shall commence during clearing, and extend through grading, placement of engineered fill, installation of recommended drainage facilities, and foundation-related work. A hold shall be placed on the "final" grading inspection, pending submittal of a report from the project Geotechnical Engineer that documents their observation and testing services to that stage of construction, including monitoring and testing of backfilling required for utility and drainage facilities. Similarly, a hold shall be placed on the final inspection for each residential building, pending submittal of a letter report from the Geotechnical Engineer documenting the monitoring services associated with implementation of final grading, drainage, and foundation-related work. This can be one letter that addresses all residential buildings, or separate letters for each building. The geotechnical monitoring shall include documentation of conformance of retaining wall, pier hole drilling/ foundation preparation work, and installation of drainage improvements. MM GEO-1c Prepare Final Construction Report The Geotechnical Engineer shall prepare a final report that documents the field observations and testing services provided during construction as well as provide a professional opinion on the compliance of construction with the recommendations in the Preliminary Geotechnical Exploration. The final report can be segmented into an as-graded report that is issued at the end of rough grading, but prior to the installation of the foundations, and a second letter commenting on the inspections made during installation of foundations/parking lot/drainage facilities. The Department of Conservation and Development, Community Development Division (CDD) will place a hold on the final inspection, to ensure that the Geotechnical Engineer’s grading-foundation inspection letter report is provided prior to requesting the final building inspection for each building. This requirement may be Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 76 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx satisfied by issuance of one letter for all residential buildings, or separate letters for each residential building. Facts in Support of Findings Impacts related to risks associated with seismic-related hazards are limited to operational impacts. Ground Rupture Based on the Geologic Peer Review (Appendix E), the potential for ground rupture is low. There are no known active faults directly crossing the project site and the project site is not located within a designated Alquist-Priolo Earthquake Fault Zone. The closest fault to the project site is the Concord fault, approximately 3 miles from the project site. As such, it is unlikely for ground rupture to occur at the site. Strong Seismic Ground Shaking Potential impacts associated with strong seismic shaking at the project site, including the areas proposed for off-site improvements, include the potential to damage structures or improvements or result in the injury or loss of human life, which could represent a potentially significant impact. The risk of damage from ground shaking is controlled by using sound engineering judgment and compliance with the latest provisions of the CBC, as a minimum. MM GEO-1a would ensure that the proposed project would incorporate all applicable seismic safety building standards contained in the CBC including seismic design provisions, which would reduce the risk of loss, injury, or death. MM GEO-1b would require geotechnical observation and testing services be conducted during construction as needed, and MM GEO-1c would require the Project Engineer to prepare a final report that documents the field observations and testing services provided during construction as well as provide a professional opinion on the compliance of construction with the recommendations in the Preliminary Geotechnical Investigation. MM GEO-1a, MM GEO-1b, and MM GEO-1c are also applicable to the off-site improvements. Furthermore, the proposed project would be required to comply with Chapter 74-2 of the Ordinance Code, which requires all construction to conform to the 2019 CBC. Seismic-related Ground Failure The potential for liquefaction at the project site is moderate to low. The areas proposed for off-site improvements are likely to contain similar soil conditions and susceptibility to liquefaction. The Preliminary Geotechnical Investigation stated that an investigation would be needed to determine whether liquefiable sands are present and to provide stabilization measures where liquefiable sands are confirmed. MM GEO-1a would require the Project Engineer to prepare a design-level Geotechnical Investigation and to incorporate all recommendation from that report into grading and construction drawings to address the presence of liquefiable sands. Landslides The project site is relatively flat with no slopes or varied topography that could be susceptible to slope failure, landslides, or soil creep. Due to the relatively flat nature of the project site, the potential for landslides is low to negligible. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 77 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx The County finds that MM GEO-1a, MM GEO-1b, and MM GEO-1c are feasible, are adopted, and will further reduce impacts associated with Geology and Soils. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Geology and Soils would be less than significant with mitigation incorporated. Potential Effect Impact GEO-2 The proposed project could result in substantial soil erosion or the loss of topsoil. (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-16). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.6, Geology and Soils, Page 3.6- 16). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures: MM GEO-2 Conduct Grading, Excavation, and Filling Only During the Dry Season All grading, excavation and filling shall be conducted during the dry season (April 15 through October 15) only, and all areas of exposed soils shall be revegetated to minimize erosion and subsequent sedimentation. After October 15, only erosion control work shall be allowed by the grading permit. Any modification to the above schedule shall be subject to review by the Grading Inspection Division, and the review/approval of the Department of Conservation and Development, Community Development Division (CDD). Facts in Support of Findings Impacts related to soil erosion or loss of topsoil are limited to construction impacts. The proposed project would be required to obtain a Construction General Permit from the State Water Board consistent with the Contra Costa County’s General Permit (No. CAS612008) and to comply with its conditions and requirements, which are designed to minimize potential erosion issues. Consistent with Section 1014-4.002 and .004, compliance with the County’s NPDES Permit would ensure that a stormwater control plan is prepared and BMPs are implemented that would prevent sediments and other pollutants from entering the stormwater system. To further reinforce protections related to erosion, MM GEO-2 would require grading, excavation, and filling to occur during the dry season. Thus, with adherence to existing regulatory requirements, as well as limiting grading, excavation, and filling to the dry season, impacts from project construction on the project site, including the off-site improvements, would not result in substantial soil erosion or loss of topsoil (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-16). The County finds that MM GEO-2 is feasible, is adopted, and will further reduce impacts associated with Geology and Soils. Accordingly, the County finds that, pursuant to Public Resources Code Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 78 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Geology and Soils would be less than significant with mitigation incorporated. Potential Effect Impact GEO-3 The proposed project could be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the proposed project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-17). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.6, Geology and Soils, Page 3.6- 18). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM GEO-1a, MM GEO-1b, and MM GEO-1c above. Facts in Support of Findings Impacts related to risks associated with location on an unstable geologic unit or soil are limited to operational impacts. The potential for liquefaction at the project site will be investigated further as part of the design-level Geotechnical Investigation, with recommendations incorporated into grading and construction drawings to address the potential presence of liquefiable sands. In addition, the potential for lateral spreading to occur as a result of the occurrence of liquefaction below the project site is low. The project site, including the areas proposed for off-site improvements, do not contain steep slopes, exposed hillsides, or vertical cuts. Due to the gently sloping nature of the project site, including the areas proposed for off-site improvements, the potential for landslides is low. According to the Soil Survey of Contra Costa County, the soil series that occurs on the project site is indicated to be very highly corrosive. Corrosive soil can damage buried metal and result in sulfate attack on foundation concrete. This is a potentially significant impact. In order to reduce or avoid potential impacts related to unstable soils, corrosive soils, or other ground failure, MM GEO-1a would be required to ensure that the proposed project incorporates all applicable seismic safety building standards contained in the CBC as well as all recommendations from a design-level geotechnical exploration. MM GEO-1b would require geotechnical observation and testing services be conducted during construction as needed, and MM GEO-1c would require the Project Engineer to prepare a final report that documents the field observations and testing services provided during construction as well as provide a professional opinion on the compliance of construction with the recommendations in the design-level geotechnical exploration. MM GEO-1a, MM GEO-1b, and MM GEO-1c are also applicable to the off-site improvements (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-17–18).

Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Geology and Soils would be less than significant with mitigation incorporated. Potential Effect Impact GEO-4 The proposed project could be located on expansive soil, as defined in Table 18-1- B of the Uniform Building Code (1994), creating substantial direct or indirect risks to life or property. (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-18). Findings Less than significant with mitigation incorporated (Draft EIR, Section 3.6, Geology and Soils, Page 3.6- 18). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures Implement MM GEO-1a, MM GEO-1b, and MM GEO-1c above. Facts in Support of Findings Impacts related to risks associated with location on expansive soil are limited to operational impacts. The Preliminary Geotechnical Investigation suggests clayey soil is present at the site, which may exhibit expansive potential. The presence of potentially expansive soil shall be further evaluated during the design-level geotechnical exploration. The soil present on-site, Clear Lake clay, is highly expansive. Expansive soils expand when water is added and shrink when they dry out. This continuous change in soils volume could cause homes and other structures to move unevenly and crack. With implementation of MM GEO-1a, MM GEO-1b, and MM GEO-1c, the proposed project, including the off-site improvements, would not create a substantial risk to life or property from being located on expansive soils (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-18). The County finds that MM GEO-1a, MM GEO-1b, and MM GEO-1c are feasible, are adopted, and will further reduce impacts associated with Geology and Soils. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Geology and Soils would be less than significant with mitigation incorporated.

Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-19). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).). Mitigation Measures MM GEO-6 Stop Construction Upon Encountering Paleontological Materials In the event that fossils or fossil-bearing deposits are discovered during construction activities, excavations within a 50-foot radius of the find shall be temporarily halted or diverted. The project contractor shall notify a qualified Paleontologist to examine the discovery. The Paleontologist shall document the discovery as needed (in accordance with Society of Vertebrate Paleontology [SVP] standards), evaluate the potential resource, and assess the significance of the find under the criteria set forth in CEQA Guidelines Section 15064.5. The Paleontologist shall notify the appropriate agencies to determine procedures that would be followed before construction activities are allowed to resume at the location of the find. If the applicant determines that avoidance is not feasible, the Paleontologist shall prepare an excavation plan for mitigating the effect of construction activities on the discovery. The excavation plan shall be submitted to the Lead Agency for review and approval prior to implementation, and the applicant shall adhere to the recommendations in the excavation plan. Facts in Support of Findings No known paleontological resources are located within the project site boundaries. The surface area of the project sites consists of solely Holocene alluvium, which is too young to contain significant vertebrate fossils. The 0.5-mile search area around the project site boundary also only contains Holocene alluvium. The nearest area with potential to contain significant fossils are resources is in the outcrop belt of Miocene Monterey Formation shale and sandstone and the Paleocene Martinez Formation. These bedrock exposures occur outside of the search area. The absence of Pleistocene or older deposits in the search area suggests that any potential paleontological resources underlying the project site would be at depths below all the earth-disturbing construction activities at the project site. In addition, there are no unique geological features located on the project site. Nonetheless, development activities have the potential to encounter undiscovered paleontological resources. Accordingly, MM GEO-6 requires the implementation of standard inadvertent discovery measures in the event paleontological resources are encountered during construction. The implementation of this mitigation measure would ensure that construction shall stop in the vicinity of any potential resource until the significance of the resource is confirmed and would ensure that Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 81 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx significant resources will be avoided or excavated and preserved (Draft EIR, Section 3.6, Geology and Soils, Page 3.6-19). The County finds that MM GEO-6 is feasible, is adopted, and will further reduce impacts associated with Geology and Soils. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Geology and Soils would be less than significant with mitigation incorporated. 1.6.6 - Hazards and Hazardous Materials Potential Effect Impact HAZ-1 The proposed project could create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-19). Findings Less than significant impact with mitigation incorporated. (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-19.) Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM HAZ-1a Conduct Asbestos and Lead Surveys Prior to Demolition Prior to the issuance of demolition permits for the existing structures, the applicant shall retain a licensed professional to conduct asbestos and lead paint surveys. These surveys shall be conducted prior to the disturbance or removal of any suspect asbestos-containing materials (ACM) and lead-based paint (LBP), and these materials shall be characterized for asbestos and lead by a reliable method. All activities involving ACM and LBP shall be conducted in accordance with governmental regulations, and all removal shall be conducted by properly licensed abatement contractors. MM HAZ-1b Proper Disposal of Hazardous Materials Such as Cleaning Supplies and Insecticides Prior to the issuance of a grading permit, the applicant shall remove and dispose of all materials observed during the site reconnaissance for the Phase I Environmental Site Assessment (Phase I ESA) in accordance with applicable local, State, and federal regulations. The materials include, but are not limited to containers of cleaning supplies and insecticides.

MM HAZ-1d Soil Aeration The applicant shall complete the soil aeration and soil vapor testing during demolition and rough grading operations. Once the soil aeration is completed which consists of spreading excavated soil on the ground in an approximately 18-inch-thick layer, mixing of the soil (tilling) shall be performed regularly to maintain aerobic conditions (presence of oxygen). The soil shall be thoroughly tilled using equipment such as a Terex RS600 Reclaimer/Stabilizer. An Environmental Health Licensed Professional shall spot-check to ensure that the process is implemented. A total of six tilling passes shall be performed through the proposed excavation area (approximately 30 feet long by 20 feet wide and 6 feet deep with a total volume of 135 cubic yards). During the tilling operation, air quality monitoring shall be performed with a photo ionization detector (PID) 3 inches above the soils and also in the breathing zone. Dust control measures shall be implemented during the aeration process (as spelled out in MM AIR-2), and dust monitoring shall be performed in the perimeter of the project site. Soil vapor sampling shall be performed at the end of aeration/tilling operations prior to backfill. If the soil vapor sampling finds no benzene Environmental Screening Level (ESL) exceedances, then the applicant shall have the Phase I Environmental Site Assessment and Phase II Environmental Investigation Report prepared by Roux Associates, Inc. (Roux) in August 2021, updated memorializing the implementation of the mitigation and confirming that no Recognized Environmental Conditions (REC) exist on the site and provide a copy to the Department of Conservation and Development, Community Development Division demonstrating that benzene levels no longer exceed the ESL. If soil vapor exceedances are identified after soil excavation and aeration, then a Soil Management Plan (SMP) shall be prepared and forwarded to an appropriate environmental oversight agency for disposition. A copy of the SMP will also be provided to the Department of Conservation and Development, Community Development Division. All construction work shall cease in the area of the underground storage tank (UST) as shown in the Roux report, including the aeration area, until the disposition of the SMP is determined by the environmental oversight agency. Once the issue has been addressed to the satisfaction of the environmental oversight agency, evidence shall be provided to the satisfaction of the Department of Conservation and Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 83 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Development, Community Development Division and construction activities may resume on the former UST area. Facts in Support of Findings During construction, both within the project site and within the areas proposed for the off-site improvements, the proposed project would be expected to involve the transport, use, and disposal of hazardous materials, such as diesel fuels, aerosols, and paints. The proposed project would be subject to the Hazardous Materials Transportation Act, California Public Resources Code, and other State and local regulations that would reduce and limit the associated risks. Any handling, transporting, use, or disposal would comply with applicable laws, policies, and programs set forth by various federal, State, and local agencies and regulations, including the EPA, RCRA, Caltrans, and HMP. During project site preparation, all existing structures, pavement, and landscaping would be demolished. Given the age of the existing structures on the project site, it is conceivable that ACM and LBP may exist within these structures, and their removal could potentially create a significant hazard to construction workers. This represents a potentially significant impact. However, implementation of MM HAZ-1a requires the applicant to conduct asbestos and lead paint surveys prior to demolition activities and to safely remove and dispose of any such materials in accordance with State standards (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-19). No hazardous materials other than small containers of conventional cleaning supplies and insecticides were observed at the project site. HAZ-1b would require proper removal and disposal of these existing materials. Three irrigation wells were observed on-site: One at a depth of approximately 60 feet below ground surface (bgs) and accompanied by a filter and a pressure tank, and two of unknown depths. One of these wells was observed to be uncovered. Should these groundwater irrigation wells be encountered during ground-disturbing activities, construction workers could potentially be exposed to a significant hazard. This represents a potentially significant impact. MM HAZ-1c requires proper closure of the three irrigation wells in accordance with local, State, and federal regulations. A 50-gallon underground storage tank (UST) was removed from the site approximately 25 years ago without regulatory oversight. Although no indication of a release has been reported and the tank was relatively small, it is possible that releases from the gasoline UST could have historically occurred, which is considered a Recognized Environmental Condition (REC). Benzene concentrations in soil vapor from all five soil vapor probes in the vicinity of the former UST exceeded the RWQCB Residential ESL. While concentrations were relatively low, to ensure no benzene ESL exceedances, HAZ-1d would require soil aeration to reduce impacts to below a level of significance. During project operations, hazardous materials may be handled on the project site. Because of the nature of the project, hazardous materials would likely be limited to small quantities of fertilizers, herbicides, pesticides, solvents, cleaning agents, and similar materials used for daily residential operations and maintenance activities. These types of materials are common for residential developments and represent a low risk to people and the environment when used as intended.

The County finds that the project, as designed and with implementation of existing regulations and mitigation, would not cause substantial adverse effects on human beings. The County finds that MM HAZ-1a, MM HAZ-1b, and MM HAZ-1c, and MM HAZ-1d are feasible, are adopted, and will further reduce impacts associated with Hazards and Hazardous Materials. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Hazards and Hazardous Materials would be less than significant with mitigation incorporated. Potential Effect Impact HAZ-4 The proposed project could be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment. (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8- 24). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-24). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures Implement MM HAZ-1d above. Facts in Support of Findings Impacts related to locating a project on a hazardous materials site per Government Code Section 65962.5 are limited to operational impacts. Based on a regulatory records review as part of the Phase I ESA, benzene concentrations in soil vapor from five soil vapor probes in the vicinity of the former 50-gallon UST exceeded the RWQCB Residential ESL. While concentrations were relatively low, to ensure no benzene ESL exceedances, HAZ-1d would require soil aeration to reduce impacts to below a level of significance (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-24). The County finds that MM HAZ-1d is feasible, is adopted, and will further reduce impacts associated with Hazards and Hazardous Materials. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Hazards and Hazardous Materials would be less than significant with mitigation incorporated.

(Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-19). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-21). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM HYD-3 Prepare Final Drainage Plan Prior to Grading • In accordance with Division 914 of the County Ordinance Code, the project shall collect and convey all stormwater entering and/or originating on this property, without diversion and within an adequate storm drainage facility, to a natural watercourse having definable bed and banks, or to an existing adequate public storm drainage system that conveys the stormwater to a natural watercourse. Any proposed diversions of the watershed shall be subject to hearing body approval. Prior to issuance of a grading permit, the applicant shall obtain a Flood Control Permit from the applicant and Permit Center, submit improvement plans for proposed drainage improvements, and a drainage report with hydrology and hydraulic calculations to the Engineering Services Division of the Public Works Department for review and approval that demonstrates the adequacy of the in- tract drainage system and the downstream drainage system. The applicant shall verify the adequacy at any downstream drainage facility accepting stormwater from this project prior to discharging runoff. If the downstream system(s) is not adequate to handle the Existing Plus Project condition for the required design storm, improvements shall be constructed to make the system adequate. The applicant shall obtain access rights to make any necessary improvements to off- site facilities.

Improvement Plans shall be reviewed to verify consistency with the Final Stormwater Control Plan and compliance with the Contra Costa Stormwater C.3 Guidebook of the County’s NPDES Permit and the County’s Stormwater Management and Discharge Control Ordinance (Division 1014) and be designed to discourage prolonged standing/ponding of water on-site. Facts in Support of Findings Construction-related Erosion and Siltation Construction activity such as grading and excavation could result in an alteration to the existing drainage pattern, potentially resulting in erosion or siltation that could result in polluted runoff exiting the site. MM HYD-3 would ensure the proposed project complies with regulations of the NPDES permit consistent with Division 1014 of the Ordinance Code. Additionally, as part of compliance with Division 1014 of the Ordinance Code, the proposed project would also be required to prepare and implement a SWPPP to ensure that erosion, siltation, and flooding are prevented or minimized to the maximum extent feasible during construction. The SWPPP includes both structural (physical devices or measures) and operational (timing of construction) BMPs that would prevent or reduce the discharge of pollutants directly or indirectly into waterbodies. As part of the SWPPP, erosion and control measures would be implemented throughout the duration of construction, including rock barrier bags placed around the catch basin until the site is paved, temporary sediment basins, placement of coarse aggregate gravel at each driveway entrance to the site such that mud or sediments would not be tracked off-site by construction vehicles, and maintenance of the site to minimize sediment entering any storm drain system in stormwater runoff. Operation-related Erosion and Siltation Development of the project site would increase impervious surfaces by 36,420 square feet compared to existing conditions and could result in increased amounts of stormwater runoff that could carry pollutants off-site. MM HYD-3 would ensure the proposed project collects and conveys stormwater entering or originating from the project site consistent with Division 1014 of the Ordinance Code. MM HYD-3 would also require the project applicant to prepare and submit a Final Storm Water Control Plan and Storm Water Control O&M Plan for review and approval by the County Public Works Department and would ensure a permanent funding source for the operation and maintenance of project stormwater facilities, which would result in a reduction of stormwaters flowing from the site compared to the current condition. In addition, the proposed project would Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 87 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx comply with the County’s NPDES program and the CCCWP as well as all relevant provisions of the Ordinance Code related to stormwater pollution, and would also be required to pay drainage fees in accordance with Flood Control Ordinance number 89-24. Construction-related Surface Runoff MM HYD-3 would ensure compliance with regulations of the NPDES permit. Additionally, the proposed project would be required to prepare and implement a SWPPP to ensure that erosion, siltation, and flooding are prevented or minimized to the maximum extent feasible during construction. The SWPPP would include both structural and operational BMPs that would prevent or reduce the amount of stormwater runoff that could be deposited directly or indirectly into waterbodies. As part of the SWPPP, erosion and control measures would be implemented throughout the duration of construction that would also limit the volume of stormwater that would be discharged. These measures would include rock barrier bags placed around the catch basin until the site is paved and temporary sediment basins that would retain stormwater to prevent significant peak flows. Operation-related Surface Runoff Under existing conditions, stormwater runoff generally sheet flows across the site or is captured by small drainage inlets on-site that connect by underground storm drain pipes and discharge into existing storm drain facilities in Jones Road and Oak Road. The proposed project would increase impervious surfaces by 36,420 square feet compared to existing conditions, which could increase surface runoff and potentially cause flooding on- or off-site. The applicant would be required to comply with Division 914 of the Ordinance Code, which addresses drainage, including provisions requiring appropriate collection and conveyance. The applicant would also be required to implement MM HYD-3, which would ensure that the site discharges to facilities with adequate capacity and that downstream facilities, if necessary, be made adequate to accommodate runoff from and through the site. As part of the proposed on-site drainage improvements, runoff from impervious areas on the project site would be routed to 34 bioretention areas for treatment before being discharged into underground storm drains; these improvements would ensure that post-construction surface runoff would be less than existing conditions (Draft EIR, Section 3.8, Hazards and Hazardous Materials, Page 3.8-19). Construction-related Exceedance of Storm Drain Capacity During construction, the proposed project could increase stormwater runoff generation, which could potentially lead to flooding on or off-site. However, the proposed project would be required to implement a SWPPP as part of its Construction General Permit to ensure that stormwater generation and pollutants are prevented or minimized to the maximum extent feasible during construction through the implementation of standard BMPs. Operation-related Exceedance of Storm Drain Capacity The proposed project would not increase impervious surfaces compared to existing conditions and, therefore, is not likely generate increased amounts of runoff. As described in the Stormwater Control Plan, the proposed project would incorporate LID techniques to allow for stormwater infiltration and treatment in 34 bioretention areas before being discharged to the storm drain system. The proposed Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 88 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx project would use 100 percent LID, meaning 100 percent of project runoff would be contained and treated on-site before being discharged. This would be accomplished by optimizing site layout and using drainage swales, curb openings, and bubble ups to convey the runoff to the treatment areas in paseos, landscape pockets between walkways/buildings, and the center open space area on the project site. Furthermore, compliance with the CCCWP and the Ordinance Code would ensure that project operation would not create runoff that exceeds the capacity of existing or planned stormwater drainage systems or provide sources of stormwater or polluted runoff. Thus, operation of the project would not create or contribute runoff water that would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff. Construction-related Impacts to Flood Flows Impacts related to impedance of flood flows would only occur during the operational phase of the project. As such, no construction impedance of flood flow impacts would occur. Operation-related Impacts to Flood Flows The project site is designated Zone X—area of minimal flood hazard. The project site is not susceptible to inundation from flood hazards, tsunamis, or seiches. As a result, the proposed project is not anticipated to have any effect in terms of impeding or redirecting flood flows. The County finds that MM HYD-3 is feasible, is adopted, and will further reduce impacts associated with Hydrology and Water Quality. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Hydrology and Water Quality would be less than significant with mitigation incorporated. 1.6.8 - Noise Potential Effect Impact NOI-1 The proposed project could cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect (Draft EIR, Section 3.11, Noise, Page 3.11-15). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.11, Noise, Page 3.11- 16). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM NOI-1 Implement Traffic Noise-reduction Measures To reduce potential traffic noise impacts, the following multi-part mitigation measure shall be implemented for the proposed project: Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 89 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx • The project applicant shall ensure inclusion of ventilation systems that would permit windows to remain closed for prolonged periods. The systems must not compromise sound insulation of the exterior wall assemblies. • Prior to issuance of building permits, the project applicant shall provide design plans which show that window and exterior door assemblies of units located within 175-feet of the centerline of Jones Road will have ratings of Sound Transmission Class (STC) 39 to reduce project traffic noise levels to meet the interior noise level standards. Alternatively, the project applicant shall provide a design-level noise study that demonstrates the specific window and door assembly sound ratings to achieve the required interior noise threshold for each of these impacted residential units. • Prior to issuance of building permits, the project applicant shall provide design plans which show that window and exterior door assemblies of units located within 100-feet of the centerline of Oak Road will have ratings of STC 34 to reduce project traffic noise levels to meet the interior noise level standards. Alternatively, the project applicant shall provide a design-level noise study that demonstrates the specific window and door assembly sound ratings to achieve the required interior noise threshold for each of these impacted residential units. Facts in Support of Findings Estimated future noise levels at future façades range from 60 A-weighted decibels (dBA) Day-Night Level (DNL) at interior shielded portions of the site to approximately 74 dBA DNL at elevated locations nearest the BART tracks and I-680. This falls into the County’s normally acceptable to normally unacceptable land use compatibility categories for multi-family residences. According to the noise study, window and exterior door assemblies of units located within 175-feet of the centerline of Jones Road will need to have Sound Transmission Class (STC) ratings of STC 39 to reduce project traffic noise levels to meet the interior noise level standards; while units located within 100 feet of the centerline of Oak Road will need to have ratings of STC 34 to reduce project traffic noise levels to meet the interior noise level standards. Implementation of the project could expose the proposed residential land uses to noise levels that would conflict with the County’s established noise land use compatibility standards adopted for the purpose of avoiding or mitigating an environmental effect. MM NOI-1 would reduce this impact to below a level of significance by requiring the project to include a code compliant mechanical ventilation system that would permit windows to remain closed for prolonged periods, as well as upgraded window and door assemblies to ensure compliance with the interior noise standard of 45 dBA DNL. This measure would ensure that potentially impacted interior residential units would meet the interior noise level requirement of 45 dBA DNL. Prior to the issuance of building permits, the project applicant would be required to demonstrate that windows and doors have been incorporated that reduce project traffic noise levels to meet the interior noise level standards. Alternatively, the project applicant would be required to provide a design-level noise study that demonstrates the specific window and door assembly sound ratings to achieve the required interior Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 90 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx noise threshold for each of these impacted residential units. Accordingly, with implementation of MM NOI-1, this impact would be reduced to less than significant (Draft EIR, Section 3.11, Noise, Page 3.11-16). The County finds that MM NOI-1 is feasible, is adopted, and will further reduce impacts associated with noise. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with noise would be less than significant with mitigation incorporated. Potential Effect Impact NOI-2 The proposed project could generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies (Draft EIR, Section 3.11, Noise, Page 3.11-17). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.11, Noise, Page 3.11- 20). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures MM NOI-2 Implement Noise-reduction Measures During Construction To reduce potential construction noise impacts, the following multi-part mitigation measure shall be implemented for the proposed project: • The construction contractor shall ensure that all equipment driven by internal combustion engines shall be equipped with mufflers, which are in good condition and appropriate for the equipment. • The construction contractor shall ensure that unnecessary idling of internal combustion engines (i.e., idling in excess of 5 minutes) is prohibited. • The construction contractor shall utilize “quiet” models of air compressors and other stationary noise sources where technology exists. • At all times during project grading and construction, the construction contractor shall ensure that stationary noise-generating equipment shall be located as far as practicable from sensitive receptors and placed so that emitted noise is directed away from adjacent residences. • The construction contractor shall ensure that the construction staging areas shall be located to create the greatest feasible distance between the staging area and noise-sensitive receptors nearest the project site. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 91 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx • The construction contractor shall control noise from construction workers' radios to a point where they are not audible at existing residences bordering the project site. • The construction contractor shall designate a "disturbance coordinator" who would be responsible for responding to any complaints about construction noise. The disturbance coordinator will determine the cause of the noise complaint (e.g., bad muffler, etc.) and will require that reasonable measures be implemented to correct the problem. • The construction contractor shall ensure that noise-generating construction activities (including construction-related traffic, excluding interior work within the building once the building envelope is complete) at the project site and in areas adjacent to the project site are limited to the hours of 8:00 a.m. to 5:00 p.m., Monday through Friday, unless otherwise approved by the Department of Conservation and Development, Community Development Division (CDD), with no construction allowed on weekends, federal, and State holidays. Facts in Support of Findings Construction Noise impacts from construction activities associated with the project would be a function of the noise generated by construction traffic, construction equipment, equipment location, sensitivity of nearby land uses, and the timing and duration of the construction activities. The transport of workers and construction equipment and materials to the project site would incrementally increase noise levels on access roads leading to the site. Because project construction workers and construction equipment would use existing routes, noise from passing trucks would be similar to existing vehicle-generated noise on these local roadways. In addition, these trips would not result in a doubling of daily traffic volumes on any of the local roadways in the project vicinity and would thus not result in a perceptible change in existing traffic noise levels. For this reason, intermittent noise from construction trips would be minor when averaged over a longer time period and would not be expected to result in a perceptible increase in hourly or average daily traffic noise levels in the project vicinity. Noise levels vary as construction progresses. Despite the variety in the types and sizes of construction equipment, similarities in the dominant noise sources and patterns of operation allow construction noise ranges to be categorized by work phase. The site preparation phase, which includes excavation and grading activities, tends to generate the highest noise levels. Construction of the proposed project is expected to require the use of scrapers, bulldozers, water trucks, haul trucks, and pickup trucks. Assuming that each piece of construction equipment operates at some distance from the other equipment, a reasonable worst-case combined noise level during this phase of construction would be 90 dBA maximum sound level (Lmax) at a distance of 50 feet from the acoustic center of a construction area. This would result in a reasonable worst-case hourly average of 86 dBA equivalent sound level (Leq). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 92 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx The nearest off-site noise-sensitive receptor to the project site is the multi-family residence located southeast of the project building, which would be located approximately 70 feet from the acoustic center of construction activity where multiple pieces of heavy machinery would operate. At this distance, construction noise levels at the exterior façade of this nearest residential home would be expected to range up to approximately 87 dBA Lmax, with a worst-case hourly average of approximately 83 dBA Leq, intermittently, when multiple pieces of heavy construction equipment operate simultaneously at the nearest construction footprint. These noise levels would be intermittent and would be reduce as equipment moves over the project site further from adjacent sensitive receptors. Therefore, restricting construction activities to non-weekend, non-holiday daytime hours of 7:00 a.m. to 6:00 p.m. would ensure that construction noise would not result in a substantial exceedance of the construction noise standards established by General Plan Policy 11-8 and the Walnut Creek Municipal Code. Additionally, MM NOI-2 requires adherence to the County’s permissible construction hours and also requires implementation of best management noise reduction techniques and practices that would ensure that construction noise levels would not result in a substantial temporary increase in ambient noise levels that would result in annoyance or sleep disturbance of nearby sensitive receptors (Draft EIR, Section 3.11, Noise, Page 3.11-18). Operation The proposed project would result in an increase in traffic on local roadway segments in the project vicinity. In addition, implementation of the project would introduce new stationary noise sources to the ambient noise environment in the project vicinity, including new mechanical ventilation equipment. The intersection volume data indicates that peak-hour traffic volumes will increase by 3 percent or less, which corresponds with less than a 1 dB increase in the traffic noise levels DNL. Therefore, project-related traffic noise level would result in less than significant increases in traffic noise levels along modeled roadway segments in the project vicinity. For project-related stationary noise sources, Contra Costa County established a maximum exterior noise performance threshold for receiving residential land uses of 65 dBA DNL. Contra Costa County also established a maximum interior noise threshold of 45 dBA DNL; however, if ambient noise levels exceed 65 dBA DNL due to train noise, the maximum interior noise threshold would be 50 dBA DNL in bedrooms and 55 dBA DNL in other habitable rooms. Implementation of the project would introduce new stationary noise sources to the ambient noise environment in the project vicinity, including new mechanical ventilation equipment. Noise levels from typical mechanical ventilation equipment range up to approximately 60 dBA Leq as measured at a distance of 25 feet. The building’s proposed mechanical ventilation units could be located as close as 30 feet from the nearest noise-sensitive receptor, which is the multi-family residential home located south of the proposed building. At this distance, noise levels generated by this equipment would attenuate to below 58.5 dBA Leq at this closest residential receptor. These noise levels would not exceed Contra Costa County’s or the City of Walnut Creek’s maximum exterior noise threshold for receiving residential land uses of 65 dBA DNL. They would therefore also not exceed the maximum interior noise threshold of 45 dBA DNL as measured inside the nearest residential receptor (Draft EIR, Section 3.11, Noise, Page 3.11-18–20). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 93 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx The County finds that MM NOI-2 is feasible, is adopted, and will further reduce impacts associated with noise. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with noise would be less than significant with mitigation incorporated. Potential Effect Cumulative Impacts The proposed project, in conjunction with other past, present, planned, and approved projects, could contribute to a cumulative impact related to traffic noise land use compatibility (Draft EIR, Section 3.11, Noise, Page 3.11-23). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.11, Noise, Page 3.11- 16). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures Implement MM NOI-1 above. Facts in Support of Findings Noise Land Use Compatibility Consistency Combined cumulative year traffic and BART activity noise levels at the project site would result in noise levels that Contra Costa County considers to be conditionally acceptable for new multi-family residential land uses (with projected noise levels of up to 74 dBA DNL at the highest impacted façade). This impact is potentially significant. However, as discussed under Impact NOI-1, MM NOI-1 shall be implemented, which requires the project to include a code compliant mechanical ventilation system that would permit windows to remain closed for prolonged periods, as well as upgraded window and door assemblies to ensure compliance with the interior noise standard of 45 dBA DNL. This measure would ensure that potentially impacted interior residential units would meet the interior noise level requirement of 45 dBA DNL. Therefore, implementation of MM NOI-1 would ensure that the project would not result in a cumulatively considerable contribution to consistency with noise land use compatibility standards (Draft EIR, Section 3.11, Noise, Page 3.11-23). Construction Noise Temporary Substantial Increase The geographic scope of the cumulative noise analysis is the project vicinity, including surrounding sensitive receptors. Noise impacts tend to be localized; therefore, the area near the project area (approximately 0.25 mile) would be the area most affected by proposed plan activities. However, none of the cumulative projects shown in Table 3-1 are located within 0.25 mile of the project site. Therefore, the cumulative impact is less than significant and the project would not have a cumulatively considerable contribution related to cumulative construction noise (Draft EIR, Section 3.11, Noise, Page 3.11-23). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 94 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Operational Traffic Noise Permanent Substantial Increase The intersection volume data indicates that project-related peak-hour traffic volumes will increase roadway traffic volumes by 3 percent or less, which corresponds with less than a 1 dB increase in the traffic noise levels DNL. Therefore, project-related traffic noise level would result in less than significant increases in traffic noise levels along modeled roadway segments in the project vicinity. This would be a less than significant impact, and no mitigation would be required. Given the above information, the project, in conjunction with other existing, planned, and probable future projects, would result in a less than significant cumulative impact related to noise (Draft EIR, Section 3.11, Noise, Page 3.11-23). Operational Stationary Noise Permanent Substantial Increase Implementation of the project would introduce new stationary noise sources to the ambient noise environment in the project vicinity, including new mechanical ventilation equipment. However, noise levels generated by this equipment would attenuate to below 58.5 dBA Leq at the closest residential receptor. These noise levels would not exceed documented existing background ambient noise levels. Therefore, implementation of the project would not result in a cumulatively considerable contribution to existing ambient noise conditions in the project vicinity (Draft EIR, Section 3.11, Noise, Page 3.11-24). Construction and Operational Vibration The only cumulatively considerable contribution to vibration conditions in the project vicinity would result from introduction of new permanent sources of groundborne vibration in the project site vicinity. The only major sources of groundborne vibration in the project vicinity is railroad activity along the rail line west of the project site. Implementation of the project would not introduce any new permanent sources of groundborne vibration to the project vicinity and would not increase railroad activity. Therefore, implementation of the project would not result in a cumulatively considerable contribution to vibration conditions in the project vicinity (Draft EIR, Section 3.11, Noise, Page 3.11-24). 1.6.9 - Public Services and Recreation Impact REC-2 The proposed project could include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-23). Findings Less than significant impact with mitigation incorporated (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-24). Changes or alterations have been required in, or incorporated into, the proposed project which avoid or substantially lessen the significant environmental effects as identified in the EIR. (State CEQA Guidelines, § 15091(a)(1).) Mitigation Measures Implement MM AIR-2, MM AIR-3, and MM NOI-2 above. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 95 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Facts in Support of Findings Impacts related to increased use of existing parks and recreational facilities are limited to construction impacts. The proposed project would include approximately 2.1 acres of private recreational facilities, including a central open space area, paseo and walkways, a dog park, and private yards. Impacts associated with the proposed amenities are analyzed in the discussion of air quality, energy, greenhouse gas (GHG) emissions, noise, and transportation-related impacts within the Draft EIR, which are explained in more detail as follows: • Air Quality: Less than significant impact with mitigation incorporated. Impact AIR-3 relates to sensitive receptors. Receptors include residences, schools and schoolyards, parks and playgrounds, daycare centers, nursing homes, and medical facilities. MM AIR-2 and MM AIR-3 would reduce construction impacts to a less than significant level. • Energy: Less than significant impact. • GHG Emissions: Less than significant impact. • Noise: Less than significant impact with mitigation incorporated. Impact NOI-2 relates to construction noise and applicable standards, and MM NOI-2 reduces impacts during construction to a less than significant level. • Transportation: Less than significant impact. Therefore, the proposed project’s construction of parks and recreational facilities on the project site would result in a less than significant impact with mitigation incorporated (Draft EIR, Section 3.13, Public Services and Recreation, Page 3.13-24). The County finds that MM AIR-2, MM AIR-3, and MM NOI-2 are feasible, are adopted, and will further reduce impacts associated with Public Services and Recreation. Accordingly, the County finds that, pursuant to Public Resources Code Section 21081(a)(1) and State CEQA Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project that mitigate or avoid the potentially significant impacts as identified in the Draft EIR. Therefore, impacts associated with Public Services and Recreation would be less than significant with mitigation incorporated. 1.7 - No Significant and Unavoidable Impacts Identified As explained in the above Findings of Fact, all of the proposed project’s impacts on the environment would either be insignificant or, through the incorporation of mitigation measures, can be reduced to less than significant. The Lead Agency hereby finds that the proposed project would not result in any significant and unavoidable impacts. The incorporation of mitigation measures outlined in the Draft EIR and the attached MMRP would fully mitigate impacts to a less than significant level. Therefore, a Statement of Overriding Considerations is not required. Nonetheless, the County has considered the benefits of the proposed project in its determination on the project as discussed in the Draft EIR and these Findings. Having considered the entire administrative record on the proposed project, the County finds that the proposed project should be implemented. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 96 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx 1.8 - Findings Regarding Alternatives 1.8.1 - Introduction This section presents findings regarding alternatives to the proposed project. The section provides a summary and discussion of the feasibility of the following alternatives evaluated in the Draft EIR: • Alternative 1: No Project, No Build Alternative. • Alternative 2: Reopening the Palmer School Alternative. In accordance with CEQA Guidelines Section 15126.6, the Draft EIR contained a comparative impact assessment of alternatives to the proposed project. The primary purpose of this analysis is to provide decision-makers and interested agencies, organizations, and individuals with information about a reasonable range of potentially feasible project alternatives, which could avoid or reduce any of the proposed project ’s significant adverse environmental effects. Important considerations for this alternatives analysis are noted below: • An EIR need not consider every conceivable alternative to a project; • An EIR should identify alternatives that were considered by the lead agency, but rejected as infeasible during the scoping process; • Reasons for rejecting an alternative include: - Failure to meet most of the basic project objectives identified in Section 2, Project Description. - Infeasibility; and - Inability to avoid significant environmental effects. CEQA does not require that an analysis of alternate sites always be included in an EIR. Pursuant to CEQA Guidelines Section 15126.6(f)(2), in making the decision to include or exclude analysis of an alternate site, the “key question and first step in analysis is whether any of the significant effects of the proposed project would be avoided or substantially lessened by putting the proposed project in another location. Only locations that would avoid or substantially lessen any of the significant effects of the proposed project need to be considered for inclusion in the EIR.” During the alternatives review process, the County conducted a review of available land near I-680 and in close proximity to the Pleasant Hill/Contra Costa Centre BART station that could support a project similar in size and type as the proposed project, and that had an appropriate General Plan land use designation and zoning classification to allow for multi-family residential land uses. An appropriate alternative vacant site was not identified within the County limits in the general vicinity. Furthermore, CEQA confirms that whether a proponent can reasonably acquire, control, or otherwise have access to an alternative site is a key factor in determining whether an off-site alternative is potentially feasible (State CEQA Guidelines § 15126.6(f)). The County, as Lead Agency, is therefore not required to select an alternative site for the proposed project. Based on CEQA Guidelines Section 15126.6, a potential alternative location was rejected as infeasible (Draft EIR, Section 4.6.3, Alternative Location, Page 4- 21). Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 97 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx 1.8.2 - Alternative 1: No Project, No Build Alternative. Under the No Project, No Build Alternative, the proposed project would not be constructed. The closed, vacant private school and its associated structures would remain on-site, and no development of any kind would occur. For the purposes of this alternatives analysis, it is assumed that the existing buildings would remain vacant and no educational, or other alternative, land use activities would occur. Findings Except for hazards and hazardous materials and land use and planning, the No Project, No Build Alternative would avoid all the proposed project’s less than significant impacts and less than significant impacts with mitigation described in Sections 3.1 through 3.16, as well as avoid the need to implement any mitigation measures. The No Project, No Build Alternative would result in greater impacts than the proposed project associated with hazards and hazardous materials; however, this impact would remain less than significant. Because this alternative would result in vacant and underutilized parcels inconsistent with land use and planning, it would result in a significant and unavoidable impact with respect to land use, which is a greater impact in comparison with the proposed project (Draft EIR, Section 4.3: Alternative 1 – No Project, No Build Alternative, Page 4-5). The No Project, No Build Alternative would not meet any of the project objectives because the project site would not be developed with 125 townhouse condominium units, including affordable units. Instead, the existing buildings on the project site would remain vacant and no educational land use activities would occur. As such, the No Project, No Build Alternative would not meet the objectives of developing an appropriate mix of multi-family units (including affordable units) that meets regional housing goals, providing affordable housing units in accordance with the Contra Costa County Housing Element (2014), locating housing in close proximity to transit in order to reduce VMT, providing housing with a variety of floor plans and unit types to enhance the economic viability of the development for long-term sustainability, replacing an obsolete private school with new market rate and affordable for-sale townhouse condominium homes consistent with the General Plan and surrounding neighborhood, and establishing physical and social connections between Jones and Oak Roads by building safe, private streets, walkable landscaped open spaces including stormwater management and green building components (Draft EIR, Section 4.3: Alternative 1–No Project, No Build Alternative, Page 4-6). Accordingly, based on the discussion in the EIR and all other evidence before it, the County finds that the No Project, No Build Alternative does not advance or meet any of the project objectives, and would result in greater impacts than the proposed project associated with land use and planning. The County rejects this alternative as infeasible. 1.8.3 - Alternative 2: Reopening the Palmer School Alternative. Under the reopening of the Palmer School Alternative, the currently closed school would reopen and resume operations as a private, nonsectarian, co-educational school, serving Junior Kindergarten to Eighth Grade students. All buildings and structures would remain in place, no trees would be removed, and no new development would take place on the project site. The school would resume operations at the same level as at the time of school closure in June 2020.

This process would include obtaining a land use permit from Contra Costa County. The school would continue its mission to offer an alternative to the larger class size and teacher ratio of public schools. The school would resume operating with a low student-to-faculty ratio and structured academic program that includes on-campus sports and community-based activities. Under this alternative, the school would return to its pre-closure enrollment of approximately 370- 400 students, employing approximately 45-52 staff members. School hours would follow pre-closure hours and would be open Monday through Friday, from 7:00 a.m. until 6:00 p.m., with grade-level specific hours as follows: Junior Kindergarten 8:30 a.m. to 11:30 a.m., Kindergarten 8:30 a.m. to 1:00 p.m., First Grade 8:30 a.m. to 2:00 p.m., Second and Third Grades 8:30 a.m. to 2:30 p.m., and Fourth through Eighth Grades 8:30 a.m. to 3:30 p.m. Consistent with the pre-closure schedule, students would be allowed on campus as early as 8:00 a.m. and could remain until 4:00 p.m. daily. An extended day program would be available before and after these hours (7:00 a.m. to 8:00 a.m. and 4:00 p.m. to 6:00 p.m.). The school would also host nighttime meetings for parents, scouting meetings, and other activities. Consistent with pre-closure activity, during the summer months, the school would offer a 10-week recreational program for children aged four to eleven years old. Activities would include arts and crafts, organized sports and games, nature study, cooking, science, swimming, camp songs and more. Summer camp would enroll approximately 100-160 students and employ approximately 25 staff members. The camp would operate Monday through Friday (with the exception of Independence Day observance) from 9:00 a.m. to 3:30 p.m. Extended day care would be offered before and after the camp hours similar to school days. Findings The Reopening the Palmer School Alternative would result in similar impacts to the proposed project’s less than significant impact without mitigation associated with population and housing, transportation, utilities and service systems, and wildfire. This alternative would lessen the severity of the proposed project’s less than significant with mitigation impacts associated with respect to aesthetics, biological resources, cultural and tribal cultural resources, geology and soils, hazards and hazardous materials, hydrology and water quality, and public services and recreation. This alternative would result in a greater, although still less than significant, impact related to energy and land use and planning. With respect to GHG emissions, this alternative would require mitigation where the proposed project would not, which would result in a greater impact than the proposed project. This alternative would result in similar or greater impacts with respect to noise. The Reopening the Palmer School Alternative would not meet any of the project objectives because the project site would not be developed with 125 multi-family residential units, including affordable units. Instead, the currently closed school would reopen and resume operations as a private K-8 school. All buildings and structures would remain in place, no trees would be removed, and no new development would take place on the project site. The school would resume operations at the same level as at the time of school closure in June 2020. As such, the Reopening the Palmer School Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 99 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx Alternative would not meet the objectives of (1) developing an appropriate mix of multi-family units (including affordable units) that meets regional housing goals, (2) providing affordable housing units in accordance with the Contra Costa County Housing Element (2014), (3) locating housing in close proximity to transit in order to reduce VMT, (4) providing housing with a variety of floor plans and unit types to enhance the economic viability of the development for long-term sustainability, (5) replacing an obsolete private school with new market rate and affordable for-sale townhouse condominium homes consistent with the General Plan and surrounding neighborhood, (6) establishing physical and social connections between Jones and Oak Roads by building safe, private streets, walkable landscaped open spaces including stormwater management and green building components, (7) providing on-site open space amenities for future residents, and (8) phase development to allow for managed, orderly, and economically viable growth. This alternative would partially meet the objective related to retaining the architectural and visual character of the neighborhood because the on-site trees would not be removed (Draft EIR, Section 4.4: Alternative 1 –Reopening the Palmer School, Page 4-17). Accordingly, based on the discussion in the EIR and all other evidence before it, the County finds that the Reopening the Palmer School Alternative does not fully meet any of the project objectives. The County rejects this alternative as infeasible. 1.8.4 - Environmentally Superior Alternative Section 15126.6(e)(2) of the State CEQA Guidelines indicates that an analysis of alternatives to a proposed project shall identify an environmentally superior alternative among the alternatives evaluated in an EIR. Each of the two project alternatives would lessen the environmental impacts relative to the proposed project to a certain degree (as described above and further in the Draft EIR). If the No Project Alternative is the environmentally superior alternative—which is the case here as it avoids all project impacts but fails to satisfy any of the proposed project objectives—the EIR must also identify another environmentally superior alternative among the remaining alternatives. Overall, based on these Findings, the Reopening the Palmer School Alternative would be considered the environmentally superior alternative, even though it would fail to fully meet all of the project ’s objectives and is therefore infeasible. 1.9 - Findings Regarding Cumulative Impacts Consistent with CEQA’s requirements, the Draft EIR for the proposed project includes an analysis of cumulative impacts. The discussion of cumulative impacts in this subsection analyzes the cumulative impacts of the proposed project, taken together with other past, present, and reasonably foreseeable future projects producing related impacts. The goal of this analysis is to determine whether the overall long-term impacts of all such projects would be cumulatively significant and to determine whether the proposed project itself would cause a “cumulatively considerable” incremental contribution to any such cumulatively significant impacts. To determine whether the overall long-term impacts of all such projects would be cumulatively significant, the analysis generally considers the following: Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 100 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx • The area in which impacts of the proposed project would be experienced. • The impacts of the proposed project that are expected in the area. • Other past, proposed, and reasonably foreseeable projects that have had or are expected to have impacts in the same area. • The impacts or expected impacts of these other projects. • The overall impact that can be expected if the individual impacts from each project are allowed to accumulate. “Cumulative impacts” refers to two or more individual impacts that, when considered together, are considerable or that compound or increase other environmental impacts (CEQA Guidelines § 15355). Cumulative impacts can result from individually minor but collectively significant impacts taking place over time (40 Code of Federal Regulations [CFR] 1508.7). If the analysis determines that the potential exists for the project, taken together with other past, present, and reasonably foreseeable future projects, to result in a significant or adverse cumulative impact, the analysis then determines whether the project’s incremental contribution to any significant cumulative impact is itself significant (i.e., “cumulatively considerable”). The cumulative impact analysis for each individual resource topic is presented in each resource section of this chapter immediately after the description of the direct project impacts and identified mitigation measures. The Draft EIR evaluated potential cumulative impacts by considering the impacts of the proposed project, taken together with other past, present, and reasonably foreseeable future projects producing related impacts. CEQA defines cumulative impacts as “two or more individual effects which, when considered together are considerable” and suggests that cumulative impacts may “result from individually minor but collectively significant projects taking place over a period of time” (State CEQA Guidelines § 15355). Additional guidance on the significance of cumulative impacts is found in CEQA Guidelines Section 15065(a)(3) which provides that a project may be individually limited but have a “cumulatively considerable” impact when the “incremental effects of an individual project are significant when viewed in connection with the effects” of past, current, and probable projects. Cumulative projects are identified in Table 3-1 of the Draft EIR. The degree to which past projects are included within the list of projects is generally limited, due to the fact that past projects are included in the current environmental conditions already considered as part of the baseline and existing environmental setting. To address cumulative impacts, the Draft EIR includes a discussion of potential cumulative effects in each topical section. Specific findings for each topical area are made above in Sections 1.5 and 1.6 of this document. Based on the Draft EIR and the entire administrative record, the County finds that potentially significant cumulative impacts can be mitigated to less than significant levels and further finds that the project would not have any environmental impacts that are individually limited but cumulatively considerable. Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact FirstCarbon Solutions 101 C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx 1.10 - Findings Regarding Growth Inducement State CEQA Guidelines Section 15126.2(e) requires a discussion of the ways in which a proposed project could foster economic or population growth or the construction of additional housing, either directly or indirectly, in the surrounding environment. Typical growth-inducing factors might be the extension of urban services or transportation infrastructure to a previously unserved or underserved area or the removal of major barriers to development. Direct Population Growth The proposed project would develop 125 new townhouse condominium units on the project site and would add an estimated 357 persons to the County’s population. This would represent an increase of 0.2 percent relative to the unincorporated population of 174,423. This amount of population growth would be within the General Plan’s 2020 population and dwelling projections for the unincorporated area and, therefore, would not be considered substantial. Furthermore, it would also be within the ABAG 2020-2040 regional population growth projections. Impacts associated with direct population growth would be less than significant (Draft EIR, Section 5.2: Growth-Inducing impacts, Page 5-2). Indirect Population Growth The proposed project is exclusively residential; it would not create new permanent employment opportunities. Thus, no indirect population growth from new employment would occur. The project site has been developed since the 1930s and is located within an urbanized area of the unincorporated County. It is served with urban infrastructure and utilities including potable water, sewer, storm drainage, electricity, and natural gas. As such, the proposed project would not remove a barrier of growth through the extension of infrastructure or utilities to an unserved area. Impacts associated with indirect population growth would be less than significant (Draft EIR, Section 5.2: Growth-Inducing impacts, Page 5-2). 1.11 - Findings Regarding Significant Irreversible Environmental Changes According to Sections 15126(c) and 15126.2(d) of the State CEQA Guidelines, the Lead Agency address any significant irreversible environmental changes that would occur should the proposed project be implemented. Generally, a project would result in significant irreversible environmental changes if any of the following would occur: • The proposed project would involve a large commitment of nonrenewable resources; • The primary and secondary impacts of the proposed project would generally commit future generations to similar uses; • The proposed project involves uses in which irreversible damage could result from any potential environmental accidents; or • The proposed consumption of resources are not justified. The proposed project consists of the development of new infill multi-family residential uses on a site that currently supports a closed private school. The site is within an urbanized area of Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 102 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx unincorporated Contra Costa County adjacent to the Walnut Creek city limits and is zoned for residential use. Construction and demolition debris recycling practices would be expected to allow for the recovery and reuse of building materials such as concrete, lumber, and steel and would limit disposal of these materials, some of which are nonrenewable. Construction of the proposed project would include the consumption of resources that are not replenishable or which may renew so slowly to be considered nonrenewable. These resources would include the following: certain types of lumber and other forest products; aggregate materials used in concrete and asphalt such as sand, gravel, and stone; metals such as steel, copper, and lead; petrochemical construction materials such as plastics; and water. Fossil fuels such as gasoline and oil would also be consumed in the use of construction vehicles and equipment. Consumption of building materials and energy is common to most other development in the region, and commitments of resources are not unique or unusual to the proposed project. Development would not be expected to involve an unusual commitment of nonrenewable resources, nor be expected to consume any resources in a wasteful manner. At operation, day-to-day activities would involve the use of nonrenewable resources such as petroleum and natural gas during operations. The new buildings’ uses would be required to adhere to the latest adopted edition of the CBC, which includes a number of standards that would reduce energy demand, water consumption, wastewater generation, and solid waste generation that would collectively reduce the demand for resources. This would result in the emission and generation of less pollution and effluent and would lessen the severity of corresponding environmental effects. Although the proposed project would result in an irretrievable commitment of nonrenewable resources, the commitment of these resources would not be significantly inefficient, unnecessary, or wasteful. Finally, the proposed project is within walking distance of the Pleasant Hill/Contra Costa Centre BART station. At a normal walking pace, it would take approximately 5 minutes to walk from the project site to the BART station (Draft EIR, Section 3.14, Transportation, Page 3.14-17). It is also within walking distance of the Iron Horse Trail, and the Contra Costa Canal Trail and employment opportunities in Contra Costa Centre. Overall, the proposed project would be expected to result in less consumption of resources than a comparable residential project at the urban edge. (Draft EIR, Section 5.3: Significant Irreversible Environmental Changes, Page 5-3). 1.12 - Custodian of Record; Scope and Content of Record The documents and materials that constitute the record of proceedings on which this Resolution has been based are located at the Contra Costa County website at https://www.contracosta.ca.gov/8363/Oak-Road-Townhouse-Condominiums.

The documents in the record include all items referenced in Public Resources Code Section 21167.6(e): (i) All project application materials; (ii) The proposed project EIR (including the Draft EIR, the Final EIR, and all appendices attached thereto); (iii) All staff reports and related documents prepared by the lead agency and/or consultants with respect to the lead agency’s compliance with the substantive and procedural requirements of this division and with respect to the action on the proposed project; (iv) All staff reports and related documents prepared by the lead agency and written testimony or documents submitted by any person relevant to any findings or Statement of Overriding Considerations adopted by the lead agency pursuant to this division; (v) All documentary and oral evidence received and reviewed at public hearings, public meetings, study sessions, and workshops on the proposed project EIR, and any transcript or minutes of the proceedings at which any advisory body or decision-making body heard testimony on, or considered the proposed project EIR; (vi) All notices issued by the lead agency to comply with this division or with any other law governing the processing and approval of the proposed project; (vii) All written comments received in response to, or in connection with, the proposed project EIR, including comments on the Draft EIR; (viii) All written evidence or correspondence submitted to, or transferred from, the lead agency with respect to compliance with this division or with respect to the proposed project; (ix) Any proposed decisions or findings submitted to the decision-makers by lead agency staff, or the proposed project proponent, project opponents, or other interested agencies, organizations and/or individuals; (x) The documentation of the final decision, including the proposed project EIR and all documents, in addition to those referenced in paragraph (c), cited or relied on in the findings or in a Statement of Overriding Considerations adopted pursuant to this division; (xi) For documentary and informational purposes, all locally adopted land use plans and ordinances, including, without limitation, general plans, specific plans and ordinances, master plans together with environmental review documents, findings, mitigation monitoring programs, and other documentation relevant to planned growth in the area; (xii) Any other written materials relevant to the lead agency’s compliance with this division or to its decision on the merits of the proposed project, including any drafts of any environmental document or portions thereof, which have been released for public review, Contra Costa County—Oak Road Townhouse Condominiums Project CEQA Findings of Fact 104 FirstCarbon Solutions C:\Users\mramirez\ADEC Solutions USA, Inc\Publications Site - Documents\Publications\Client (PN-JN)\2648\26480017\FOF\26480017 Contra Costa County Oak Road Townhouse Condominiums FOF.docx and copies of studies or other documents relied upon in any environmental document prepared for the proposed project and either made available to the public during the public review period or included in the lead agency's files on the proposed project, and all internal agency communications, including staff notes and memoranda related to the proposed project or to compliance with this division; (xiii) The full written record before any inferior administrative decision-making body whose decision was appealed to a superior administrative decision-making body prior to the filing of litigation; and (xiv) Any additional items not included above if otherwise required by law. 1.13 - Recirculation Not Required During the public review period after the Draft EIR was published, the Lead Agency received one comment letter that did not raise any significant environmental issues requiring any changes to or clarifications of the EIR. The Lead Agency has considered all relevant information including the opinions and comments of interested agencies, organizations, and individuals. The Lead Agency finds that none of the following situations requiring recirculation identified in CEQA Guideline 15088.5 have occurred: 1. A new significant environmental impact that would result from the proposed project (or any alternative) or from a new mitigation measure proposed to be implemented. 2. A substantial increase in the severity of an environmental impact would result unless mitigation measures are adopted that reduce the impact to a level of insignificance. 3. A feasible project alternative or mitigation measure considerably different from others previously analyzed would clearly lessen the significant environmental impacts of the proposed project (or an alternative), but the proposed project's proponents decline to adopt it. 4. The Draft EIR was so fundamentally and basically inadequate and conclusory in nature that meaningful public review and comment were precluded. Based on the foregoing and as explained in more detail in the Final EIR, and having reviewed all the information in the record of proceedings, the Lead Agency hereby finds that there was no significant new information nor was there information that required recirculation of the EIR. The additional information merely clarifies or amplifies an adequate EIR.

PROJECT FINDINGS FOR CONDITIONS OF APPROVAL FOR SUMMERHILL HOMES (APPLICANT) AND SAM MENDES, ET. AL (OWNERS): COUNTY FILES #CDRZ21- 03258, CDSD21-09559, CDDP21-03001 A. General Plan Growth Management Element Findings 1. Traffic: Implementation Measure 4-c under the Growth Management Program (GMP) of the County’s General Plan requires a traffic impact analysis be conducted for any project that is estimated to generate 100 or more AM or PM peak-hour trips. The project involves the construction of 125-unit townhouse condominiums and therefore, a Traffic Impact Assessment was prepared (TIA). According to the Contra Costa County Transportation Analysis Guidelines, a project is expected to result in a less-than-significant vehicle miles traveled impact if the proposed project is located within ½ mile of an existing major transit stop or an existing stop along a high-quality transit corridor. The Pleasant Hill BART station, which is an existing major transit stop, is located within ½ mile from the project site. In addition, there are bicycle and pedestrian facilities between the project site and the Pleasant Hill BART station. There are continuous sidewalks along Jones Road and Oak Road that connects to the project site and the Pleasant Hill BART station. Furthermore, a Transportation Demand Management Plan (TDM) is prepared as part of this project, which includes a range of TDM measures designed to reduce single-occupant vehicle trips and encourage residents to walk, bike or use transit services. The project is conditioned to require the review and approval of the TDM plan. The project generated traffic would access the site via a new driveway connecting to Jones Road. There will also be a proposed driveway that will connect to the project site on Oak Road. The new driveway on Jones Road will be 26 feet wide, which can accommodate two-way traffic. The site plan shows that the Oak Road driveway would be approximately 26 feet. The 26 feet driveway width will be adequate for emergency vehicle access. Overall,, the project would not cause unacceptable traffic related impacts in the immediate vicinity or area. 2. Water: Water supply would be provided to the proposed project by the CCWD. Because the project site is currently served by the CCWD, its water consumption is factored into the UWMP’s planning projections. Thus, adequate water supplies are available to serve the project and no new or expanded water treatment or Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 2 of 8 conveyance facilities would be required. CCWD provided a letter to the applicant dated November 10, 2020, confirming it could serve the project and providing standard requirements for new service connections (e.g., separate metering of domestic, fire, and irrigation). Thus, adequate water supplies would be available to serve the project from existing and planned supplies. 3. Sanitary Sewer: The project is within the service area of the Central Contra Costa Sanitary District (CCCSD) who provides wastewater services for the project. A new on-site sewer collection system consisting of 8-inch diameter pipes that would discharge via service lateral to an existing 18-inch diameter sewer line in Jones Road would be installed for the project. The CCCSD provided comments to the applicant dated August 4, 2020, confirming it could serve the project providing standard requirements for new service connections (e.g., payment of connection fees). Thus, the CCCSD Treatment facility would have sufficient capacity to serve all aspects of the project. 4. Fire Protection: Four fire stations are located within approximately 2 miles of driving distance of the project site: Station No. 1, located at 1330 Civic Drive in Walnut Creek, is approximately 1.7 miles (driving distance) south of the project site; Station No. 2, located at 2012 Geary Road in Pleasant Hill, is approximately 1.4 miles (driving distance) west of project site, Station No. 5, located 205 Boyd Road in Pleasant Hill, is approximately 1.9 miles (driving distance) north of the project site; and Station No. 10, located at 2955 Treat Boulevard in Concord, is approximately 2.2 miles (driving distance) northeast of the project site. The DEIR prepared identified response time from Station No. 2 to the project site would be in 2 minutes and 24 seconds, which is under the 5-minute response standard set by the County’s General Plan. The project would comply with the California Building Standards Code (CBC), which is adopted by the Ordinance Code. In compliance with the California Fire Code, Part 9 of the CBC, during construction the project would follow standards for fire safety related to provision of fire apparatus access and acquisition of building permits. With an adequate fire engine response time to the project site, adherence to the CBC Codes, adequate project site access, and payment of impact fees to the CCCFPD, the project would Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 3 of 8 not create a need to construct new or expand existing fire protection or emergency medical services facilities. 5. Public Protection: The County General Plan Policy 7-57 indicates a Sheriff facility standard of 155 square feet of Sheriff station space per 1,000 persons of population. The square footage of the Valley Station is estimated to be approximately 5,372 square feet. The proposed project would increase the population of unincorporated Contra Costa County by approximately 357 persons. Accordingly, the project would require 55 square feet of Sheriff station space. This increased demand for Sheriff station space represents approximately 1 percent of the Valley Station’s existing square footage and, thus, represents a nominal increase in demand. Additionally, the Office of the Sheriff did not indicate that the proposed project would result in the need for new or expanded Sheriff facilities in order to maintain acceptable service ratios, response times, or other performance objectives. As such, the project would not adversely affect service ratios or response times or increase the use of existing police protection facilities such that substantial physical deterioration, alteration, or expansion of these facilities would be required, thereby triggering environmental impacts. Furthermore, the Condition of Approval (COA) # 13 requires the formation of a police services district to provide funding to maintain and augment police services. 6. Parks and Recreation: As the project will add to the County’s population, COA #10 and 11 requires the project proponent to pay applicable Park fees per unit. The Park Impact fee collected will be used for acquisition of parkland and development of parks and recreational facilities. The Park Dedication requirement allows the developer of land for residential use to dedicate land, pay an in-lieu fee, or a combination of both for neighborhood and community park or recreational purposes. Furthermore, the project includes outdoor recreational amenities, such as a dog park and outdoor seating areas within the courtyards to be used by the residents of the development. 7. Flood Control and Drainage: The project is in Zone X, as designated on the Federal Emergency Management Agency’s Flood Insurance Rate Maps. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 4 of 8 The project site is relatively flat, sloping gently northeast. Site drainage as proposed is directed to C.3 facilities and then conveyed to existing drainage lines along Jones Road and Oak Road. Prior to entering the existing the drainage is to be directed into hydromodification vaults. The existing drainage infrastructure in Jones Road and Oak Road are Line C and Line D-1 of Drainage 44B respectively. The site drainage may have to be revised to accommodate for the treatment of the proposed private roads. B. Rezoning Findings (County Code Section 26-2.1806) 1. Required Finding: The change proposed will substantially comply with the general plan. Project Finding: The project site is located within a Multiple-Family Residential- High Density (MH) General Plan land use designation. Primary land uses in the MH land use designation include attached single-family residences (such as duplexes or duets), multiple-family residences such as condominiums, town houses, apartments, and mobile home parks, and accessory buildings and structures normally auxiliary to the primary uses. The project is a use that is consistent with the MH land use designation. The project requires a rezone of the project site to a Planned Unit District (P-1) to allow 125-unit townhouse condominiums. Table 3-5 of the County’s General Plan indicates that a P-1 zoning district is consistent with the MH land use designation. The project is a transit-oriented and infill project that is consistent with other General Plan policies that promotes housing near the Pleasant Hill/Contra Costa Centre BART Station and encourages other modes of transportation (e.g., transit, bicycling), while providing additional units to the County’s housing inventory. Thus, the rezoning of the 5.94-acre project site will substantially comply with the County’s General Plan. 2. Required Finding: The uses authorized or proposed in the land use district are compatible within the district and to uses authorized in adjacent district. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 5 of 8 Project Finding: The project site is approximately 0.25 miles south of the Pleasant Hill/Contra Costa Centre BART Station, and is surrounded by a number of multiple-family residential developments. The project is a use consistent with the MH General Plan land use designation. Overall, the project is in harmony with the surrounding area and the uses established in the area. 3. Required Finding: Community need has been demonstrated for the use proposed, but this does not require demonstration of future financial success. Project Finding: The 5.94-acre project site was the location of the former Palmer School for Boys and Girls, a private K-8 school that closed in 2020. The project is an infill project that is located within an area that is developed with multiple- family residential and office uses. The project to construct the 125 townhouse condominium units will improve the current vacant use of the project site. Further, the 2005-2020 Contra Costa County General Plan contains policies related to providing an adequate supply of housing and encouraging infill development on under-utilized sites within urbanized areas where necessary utilities already are installed. This project is consistent with the surrounding area consisting of residential development near transit. Furthermore, the project is consistent with the MH General Plan land use designation. C. Tentative Map Findings (County Code Section 94-2.806) 1. Required Finding: The advisory agency shall not approve a tentative map unless it finds that the proposed subdivision, together with the provisions for its design and improvement, is consistent with the applicable general plan required by law. Project Finding: The project is located within the unincorporated Walnut Creek community, where the surrounding uses include primarily of residential developments and office uses. The tentative map would subdivide the 5.94-acre project site into 19 residential lots to construct 19 buildings for a total of 125 townhouse condominium units. The project is consistent with the proposed General Plan land use designation of Multiple-Family Residential- High Density (MH), which allows 22.0 – 29.9 units per net acre. The net acreage for the 5.94- acre site is 4.71 acres. The project to construct 125 units allows a density of 26.5 units per net acre, which results in a density of within the MH density range. Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 6 of 8 Overall, the project is consistent with the applicable policies for the MH land use designation, as well as transportation and housing policies of the General Plan. 2. Required Finding: The advisory agency shall not approve a tentative map unless it shall find that the proposed subdivision fulfills construction requirements. Project Finding: The project will comply with the collect and convey regulations, storm drainage facilities, and design standards for private roads. Additionally, compliance with the California Building Code and all applicable County Ordinances is required for grading of the property and construction of residential buildings. D. Findings of Approval of P-1 Zoning District and Final Development Plan (County Code Section (84-66.1406) 1. Required Finding: The applicant intends to start construction within two and one- half years from the effective date of the zoning change and plan approval. Project Finding: The applicant has indicated that they intend to commence construction within 2 ½ years off the effective date of the zoning change and plan approval. 2. Required Finding: The proposed planned unit development is consistent with the County General Plan. Project Finding: The project site is located within a Multiple-Family Residential- High Density (MH) General Plan land use designation. Primary land uses in the MH land use designation include attached single-family residences (such as duplexes or duets), multiple-family residences such as condominiums, town houses, apartments, and mobile home parks, and accessory buildings and structures normally auxiliary to the primary uses. The project is a use that is consistent with the MH land use designation. The project requires a rezone of the project site to a Planned Unit District (P-1) to allow 125-unit townhouse condominiums. Table 3-5 of the County’s General Plan indicates that a P-1 zoning district is consistent with the MH land use designation. The project is a transit-oriented and infill project that is consistent with other General Plan policies that promotes housing near the transit such as Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 7 of 8 the Pleasant Hill/Contra Costa Centre BART Station and encourages other modes of transportation (e.g., transit, bicycling), while providing additional units to the County’s housing inventory. Thus, the rezoning of the 5.94-acre project site will substantially comply with the County’s General Plan. The County’s General Plan provides Housing goals and policies that promote and encourage projects, such as this project within the unincorporated Walnut Creek area. Goal 6 of the County’s Housing Element identifies the need to provide adequate sites with the appropriate land use and zoning designations to accommodate the County’s share of regional housing. The project site was the former location of the Palmer School for Boys and Girls, which closed in June 2020. The project would provide 125-units on a site that is underutilized and located within ½ mile of the Pleasant Hill/Contra Costa Centre BART Station. The project includes the rezoning of the property to P-1, which is consistent with the General Plan Land Use designation of MH. Policy 3-8 of the General Plan encourages infilling of already developed areas, where new development is preferred to vacant or under-used sites within urbanized areas, which have necessary utilities installed. The County’s General Plan also provides Transportation goals and policies that supports the project. The project is a transit-oriented, infill development project that provides the much-needed housing units near the Pleasant Hill/Contra Costa Centre BART Station. Overall, the project is consistent with the County’s General Plan, especially the goal to reduce greenhouse gas emissions by providing housing within an area that provides multimodal access. 3. Required Finding: In the case of residential development, it will constitute a residential environment of sustained desirability and stability, and will be in harmony with the character of the surrounding neighborhood and community. Project Finding: The surrounding area consists of residential uses, primarily of multiple-family residential development. The 125-unit townhouse condominiums will consist of 48 three-bedroom units and 77 four-bedroom units ranging in size from 1,362 – 2,281 square feet of living area. The project site is located within an established neighborhood that consisting primarily of multiple-family development within ½ mile of the Pleasant Hill/Contra Costa Centre BART Station Oak Road Townhouse Condominium Project County Files: #CDRZ21-03258, CDSD21-09559, CDDP21-03001 CPC, January 26, 2022 Page 8 of 8 and walking distance to the Iron Horse Regional Trail. The project site is located within an area that is accessible to different modes of transportation (e.g. bicycle, transit, etc.). Overall, the proposed development will be in harmony with the surrounding area. 4. Required Finding: The development of a harmonious integrated plan justifies exceptions from the normal application of this code. Project Finding: The project site is 5.94 acres in size that is currently zoned Multiple-Family Residential (M-17 and M-19) and Single-Family Residential (R- 15). The MH General Plan land use designation permits multiple-family residences such as condominiums, town houses, and apartments, consistent with the project to establish 125 townhouse condominium units. Applying the required setbacks for the current zoning districts would not be feasible, as the 5.94-acre project site is smaller in size for the higher density that the site is planned for. Additionally, the project site has three different zoning districts, in which the R-15 zoning designation is not consistent with the MH General Plan land use designation. Directly northeast and directly south of the project site are developments that are also zoned a Planned Unit District (P-1). Overall, the project will remain for residential use consistent with surrounding area. E. Tree Permit Findings (County Code Section 816-6.8010) Required Finding: The County Planning Commission is satisfied that the following factors as provided by County Code Section 816-6.8010 for granting a tree permit have been satisfied: 1. Reasonable development of the property will require the removal of 74 trees, relocation of one tree, and work within the dripline of an additional six trees will be necessary to construct the project. All feasible efforts have been made to retain the maximum number of trees, as well as, to preserve those trees, which are exceptional due to their visual prominence on the site. 2. Development of this project cannot be reasonably accommodated on other parts of the property due to the size of the project site.

These laterals would be inadequate to serve the proposed project and would need to be properly abandoned. The developer would need to construct an on-site public main and laterals. The proposed project would produce a significant added capacity demand on the wastewater system, given the project’s size and location adjacent to sewers that are downstream of a large number of connections. Nonetheless, Central San has conducted a capacity analysis and determined that the downstream sewer system has sufficient capacity to accommodate the project. The payment of capital improvement fees is required for developments that generate an added wastewater capacity demand to the sanitary sewer system. This project would be subject to substantial capital improvement fees due to its size. The applicant must submit full- size building plans for Central San Permit staff to review and pay all appropriate fees. For more information, the applicant should contact the Central San Permit Section at (925) 229-7371. Thanks!

Agency Comment RequestForm Open 1666 North Main Street, Walnut Creek, CA 94596 tel 925.943.5899 www.ci.walnut-creek.ca.us February 2, 2021 Jennifer Cruz Contra Costa County Department of Conservation and Development 30 Muir Road Martinez, CA 94553 Delivered via e-mail Re: RZ21-3258; SD21-9559; DP21-3001 (SummerHill Homes) Dear Ms. Cruz: Thank you for the continued opportunity to review the above noted application located within the City of Walnut Creek’s Sphere of Influence. Our comments on this proposed project are as follows: Planning/Land Use 1. This project does not appear to comply with the City’s general plan land use classification for the subject property is Multifamily Medium High (MFMH), which calls for residential densities between 22.1 and 30.0 dwelling units per acre, because the City does not discount the land used for internal private driveways when calculating net lot area. As such, the project should be revised to include more dwelling units. Additionally, given the project site’s location in close proximity to the Pleasant Hill BART station, and the regional housing need, consideration of further increases in density as part of the County’s general plan update would be appropriate. 2. Pursuant to Action 18.5.3 in Chapter 4 of the Walnut Creek General Plan, all utilities will need to be placed underground (this will be required by the City for all utilities located in the adjacent City of Walnut Creek right-of-way for Oak Road). 3. We ask that any impact or development fees collected from this project for the purpose of constructing or maintaining parks facilities (such as Quimby Act fees) be passed on to the City of Walnut Creek, as there are few County park facilities in the area, and the project’s future residents would most likely use the nearby City of Walnut Creek park and open space facilities (including Walden Park). 4. We recommend that a plaque or other similar device be located where it can be read from the sidewalk of either or both Oak and Jones Roads, telling the history of the Palmer School on this site. 5. In light of the site’s proximity to the Pleasant Hill BART station, the Contra Costa Canal Trail, and the Iron Horse Trail, we recommend that the project include secure indoor bicycle parking for the project’s residents, and convenient outdoor bicycle parking for visitors. Public Works - Traffic Engineering 6. In order to meet the transit-proximate CEQA exemption for traffic impacts related to VMT, the applicant must show that excess parking is not being provided on site that would result in a mode shift that increases trips made by auto rather than active and transit trips. This would result in the transit-proximate CEQA exemption for traffic impacts not being applicable for this development. Should the exemption not be applicable due to parking provided in excess of the demand and/or required amount and/or consistency in quantity of parking provided in the area, the applicant must prepare a VMT analysis consistent with the recent guidelines published by the County due to project size. Public Works – Engineering 7. The eastern property line of the subject site abuts the City of Walnut Creek’s right-of- way for Oak Road. Thus all frontage improvements along Oak Road shall be reviewed, approved, permitted, and inspected by the City of Walnut Creek. 8. An encroachment permit is required for all work within the City of Walnut Creek public right-of-way for construction of frontage improvements at Oak Road frontage and for any utility connections beneath Oak Road. 9. The developer shall repair any damaged sidewalk, curb and gutter, relocate the existing driveways to new location(s), and construct and dedicate the improvements within the City's right of way, including concrete curb, gutter, minimum 10-ft sidewalk, and paving, drainage system, street lights, striping, signage, and street trees, all to the satisfaction of the City Engineer. The existing street section shall be removed and replaced to the centerline of the street if the existing structural section is cracked or damaged in any way, all to the satisfaction of the City Engineer. (per W.C.M.C. Sec. 9-9.205 and 9-9.206) 10. All sidewalks shall comply with ADA and Title 24 requirements for cross slope, including driveway approaches and curb ramps. 11. A photometric study shall be submitted to the City of Walnut Creek for Oak Road. Any adjustments to bring Oak Road street lighting up to City standards will be incorporated into final permit drawings. Street lights on Oak Road shall be per City Standards. 12. Utility structures serving the project must be located outside of the public right-of-way. 13. Current site storm drain facilities tie into City of Walnut Creek’s storm drain on Oak Road. If not proposed to be used, abandonment (removal) of these connections will be required. 14. The downstream drainage system shall be analyzed, and inadequacies, if any, corrected as determined by the City Engineer. Analysis shall include drainage upstream and downstream for existing hydrology passing through the site and shall also confirm system adequacy two structures beyond (downstream of) the connection point. 15. Post-project stormwater peak flows shall be metered on-site to match pre-development peak flows for at 10-year storm event. The method for metering stormwater flows shall be approved by the City Engineer. 16. Work hours in the City of Walnut Creek right-of-way are 7 am to 6 pm Monday through Friday, excluding City holidays. Nonstandard hours, holiday, and weekend work requires an After Hours Work permit. Permits are issued or denied on a case-by-case basis depending on type of work to be performed, proximity to residents, and requirements for inspection if any. Thank you for considering our comments in your review of this application. Please don’t hesitate to contact me directly if you would like to discuss any aspect of this letter further or if you have any questions. Sincerely, Andrew M. Smith Senior Planner (925) 943-5899 x2213 asmith@walnut-creek.org Page 1 TO: Jennifer Cruz FROM: Stan Muraoka, AICP DATE: June 2, 2021 SUBJECT: DP21-3001/RZ21-3258/SD21-9559 SummerHill Homes Townhouse Condominiums The following are Housing Programs’ revised comments on the applicant’s Inclusionary Housing Plan for the proposed SummerHill Homes Oak Road Townhouse Condominiums. The comments are based on the applicant’ resubmittal of certain documents on May 21, 2021, including the Illustrative Site Plan (Sheet A4), the Unit 1 Floor Plans (Sheet A7), and the 21-05-14 Revised Unit Mix table, accompanied by Marshall Torre’s email dated May 21, 2021. Copies of these documents are attached. Inclusionary Requirement: A residential development of five or more for-sale units is subject to the County’s Inclusionary Housing Ordinance. Thus, an Inclusionary Housing Plan is required as part of this application. Pursuant to Section 822 -4.402 (b) of the Ordinance, at least 15% of the units shall be developed and sold as inclusionary units under the terms and conditions of Section 822-4.410 (b). At least 20 percent of the inclusionary units shall be sold at an affordable sales price to lower income households, and the remaining inclusionary units shall be sold at an affordable sales price to moderate-income households. As an alternative to providing some or all of the inclusionary units required by the County Ordinance, an in-lieu fee may be paid. Based on the Ordinance, the applicant is required to provide 18.75 inclusionary units in the proposed 125-unit for-sale townhouse development at the Jones Road/Oak Road site. Inclusionary Development Standards: A qualifying inclusionary housing development application must comply with inclusionary development standards. As detailed in Section 822-4.412 of the Ordinance, these standards include the following: (a) Inclusionary units must be dispersed throughout the residential development and have access to all on-site amenities that are available to market rate units. (b) The construction quality and exterior design of inclusionary units must be comparable to the market rate units. However, inclusionary units may be smaller in size, developed on smaller lots, and have alternative interior finishes. CONTRA COSTA COUNTY Department of Conservation and Development 30 Muir Road Martinez, CA 94553 Telephone: (925) 655-2705 Fax: (925) 655-2758 Page 2 (c) The average number of bedrooms for all inclusionary units must be equivalent to the average number of bedrooms for market rate units within the same residential development. (d) All inclusionary units must be constructed and occupied prior to or concurrently with the market rate units within the same residential development. For phased residential developments, the inclusionary units may be constructed and occupied in proportion to the number of dwelling units in each phase of the project. Proposed Inclusionary Housing Plan As required under Section 822.4.414 of the Inclusionary Housing Ordinance, the application for the proposed SummerHill Home Townhouse Condominiums must include a housing plan. The project applicant submitted a proposed inclusionary housing plan on February 22, 2021 that was subsequently modified by the documents resubmitted on May 21, 2021 . Staff has reviewed the proposed inclusionary housing plan and finds that the plan does not comply with County Code Section 822-4.402(b); however, staff accepts the construction of ten inclusionary housing units to be provided to moderate income households and the payment of an in-lieu fee for 8.75 inclusionary housing units as an exception due to the unique characteristics of the development. Regarding compliance with inclusionary development standards of Section 822-4.412, the proposed six 4-bedroom and four 3-bedroom inclusionary housing units shown on the May 21, 2021 Illustrative Site Plan are located in six buildings on Street A, Court A, Court D, and Court F, and therefore, staff is able to make a finding that the inclusionary units are dispersed throughout the development. Based on the May 21, 2021 Illustrative Site Plan, Unit 1 Floor Plans, and Revised Unit Mix table, staff has determined the development to comply with the requirement for the average number of bedrooms for all inclusionary units to be equivalent to the average number of bedrooms for market rate units. Staff acknowledges the applicant’s statements that the inclusionary units will be of the same quality and exterior appearance as the market rate units and will be constructed and occupied concurrently with the market rate units. Thus, staff has determined that the proposed inclusionary housing plan is in compliance with all required inclusionary development standards. Staff notes that there is a numerical discrepancy in the unit net square footage and the unit gross square footage shown on the Unit 1 Floor Plans and in the Revised Unit Mix table for the 4-bedroom inclusionary units, and recommends that the applicant update the net and gross square footages on these documents as appropriate. There should be no numerical discrepancies in the final documents considered for approval. Page 3 Compliance with Inclusionary Housing Ordinance The proposed inclusionary housing plan received on February 22, 2021, as modified by the documents resubmitted on May 21, 2021, complies with the Inclusionary Housing Ordinance. Staff will forward to you Conditions of Approval ensuring compliance with the Inclusionary Housing Ordinance for inclusion in the DP21-3001/RZ21-3258/SD21-9559 Findings and Conditions of Approval. If you have any questions regarding these comments, call me at 925-655-2876 or email me at stanley.muraoka@dcd.cccounty.us.

As we discussed at our recent meeting please consider this email and attachments an update to the 2-1-21 Oak Road Townhome Condominium Project Inclusionary Housing Plan (Plan) including the attached 5-14-21 Revised Unit Mix Matrix, the new 4 BR-3 BA-1 Car Garage Inclusionary Unit Floor Plan (which may be reduced in SF in its final design) and Site Plan showing the location of the ten (10) for sale inclusionary units to buyers with moderate income. The inclusionary units are of the same quality and exterior appearance as the market rate units, are dispersed around the site and will be constructed, marketed and sold in phases along with the adjoining market rate units. Six (6) 4 BR and four (4) 3 BR inclusionary units will be provided meeting the inclusionary ordinance average project bedroom count standard for the project which is 60% 4 BR Units. An in lieu fee will be paid for the 8.75 unit remainder of the 18.75 unit inclusionary obligation. Per our discussion it is my understanding that upon receipt of this submittal County Staff will be in a position to confirm the Plan has received “Preliminary Staff Approval” thereby allowing the Oak Rd planning application to be “deemed complete” once the five (5) comments listed in the attached 4-23- 21 3rd Notice of Incomplete Application for the Oak Road Project Letter are satisfied. Finally, I believe these five (5) comments have been satisfactorily addressed by virtue of previous submittals and related exhibits. We would like to thank you all for working collaboratively with us on this exciting project that will be providing 3 and 4 BR for sale inclusionary units to the neighborhood instead of paying an in lieu fee as permitted by the inclusionary ordinance. Your guidance, assistance and cooperation is very much appreciated.

Please let me know if you have any questions and/or direct Hexagon staff to contact me directly if necessary. Comments Memo 1. Please have the consultant identify in the Memo the Multimodal Transportation Service Objective (MTSO) of 1.5 V/C as the level of service (LOS) standard for the intersection of Oak Road and Treat Boulevard, per the Central County Action Plan.1 A discussion of the project’s impacts on this intersection should include whether the addition of trips generated by the project would result in the intersection’s operations exceeding the 1.5 V/C threshold. 2. Please have the applicant eliminate the four proposed on-street parking spaces along Oak Road. Draft TDM Plan 3. Page 12 (“Online Transportation Kiosk” section): The bullet point, “A summary of County Connection and BART services and links to further information about their routes and schedules,” should list other transit service providers that serve the surrounding area, including at the Pleasant Hill BART Station. 4. Page 13 (“Proximity to Transit Center” Section): Please have the consultant include references to other transit agencies that serve the Pleasant Hill BART Station. It is suggested using the same information that was provided in the “Existing Transit Facilities” section on 1 The Central County Action Plan (link) identifies Treat Boulevard as a Route of Regional Significance (RORS). All RORS have Multimodal Transportation Service Objective (MTSO) performance standards. The MTSO for all Treat Boulevard intersections in Unincorporated Contra Costa County is a 1.5 V/C ratio, as seen on page 40 of the document.

Balbas, Director Deputy Directors Stephen Kowalewski, Chief Allison Knapp Warren Lai Carrie Ricci Joe Yee Memo April 28, 2021 TO: Randolf Sanders, Engineering Services FROM: Alexander Zandian, Transportation Engineering SUBJECT: DP21-3001 SummerHill Homes Land Development Application Transportation Engineering staff has reviewed the Draft Transportation Analysis Memo and Draft Transportation Demand Management Plan to identify traffic impacts associated with the SummerHill Homes Development located in unincorporated Walnut Creek. Staff provides the following comments and suggestions. TRANSPORTATION ANALYSIS COMMENTS: 1.Oak Road access to the development site should be limited to emergency vehicle access only. Contra Costa County’s General Plan discourages new access points on major roadways. 2.The “Observations” section on Page 4 states that field observations of traffic operations were taken in March 2021 during the Covid-19 pandemic. Due to reduced traffic on our roadways, normal traffic deficiencies cannot be assessed. Suggest removal of this section from the Transportation Analysis Memorandum. 3.The “Bicycle Facilities” section on Page 14 states that the City of Walnut Creek’s “Walnut Creek Bicycle Plan” includes a plan to provide a bicycle route on Jones Road between Treat Boulevard and Walden Road. Jones Road south of the Contra Costa Canal Trail to Walden Road is in the jurisdiction of the City of Walnut Creek. Is the City of Walnut Creek coordinating with the County to provide for a seamless bicycle route on Jones Road between Treat Boulevard and Walden Road? 4.The “Vehicle Parking” section on Page 17 is planning to provide four (4) on-street parking spaces on the project’s Oak Road frontage to comply with CCC Parking Standards for Guest Parking. All guest parking shall be provided on site. AZ Randolf Sanders April 28, 2021 Page 2 of 2 TRANSPORTATION DEMAND MANAGEMENT PLAN COMMENTS: 5. In addition to the online kiosk measure, the applicant shall provide a kiosk structure on the premises for those that do not have access to online devices. AZ G:\transeng\EIR\Walnut Creek\SummerHill Homes (DP21-3001)\TE Memo SummerHill (TDM & TA) 4.27.2021.docx c: Jerry Fahy, TE Jeff Valeros, TE Monish Sen, TE Robert Sarmiento, DCD From:Alexander Zandian To:Robert Sarmiento Cc: Subject: Date: Randolf.Sanders; Jennifer Cruz RE: SummerHill Homes DP21-3001 Thursday, May 6, 2021 1:01:42 PM Hello all, Our senior traffic engineer looked at the site plans in more detail and has generated some additional comments for our discussion today. 1. None of the Alleys on-site have turnarounds at the terminii. 2. In addition, there is, what appears to be, parking stalls at the terminii. Those parked vehicles would have difficulty exiting the stalls. 3. Single access point on Jones intersects at an angle, which is unacceptable. 4. It should come in perpendicular to Jones, and be a street type connection and much wider than 20' for accepting turning vehicles. 5.Sight lines at the new access would have to be provided. 6. The Oak Road access I have earlier addressed. It also appears to be a driveway type intersection. Has Walnut Creek weighed in? 7.They appear to show parking spaces on Oak and Jones (existing?) to meet their parking requirements. Not acceptable. Alexander Zandian Staff Engineer (925) 313-2052 To: Jennifer Cruz, Contra Costa County DCD Subject: Palmer School Redevelopment Proposal at 2740 Jones Rd, Walnut Creek We welcome and appreciate the opportunity to comment on this project. Walden District Improvement Association has served 7,000 homes in northern Walnut Creek and abutting areas of Pleasant Hill and Concord for over 60 years. First and foremost, we are very happy to see a proposal for residential ownership rather than more rental units which have come to dominate the area. Ownership creates community and lasting relationships. Second, we appreciate the proposed density being kept to a conforming per-acre count of 21 units. Third, we do have concern over the placement of units along Oak Road in that they appear to require the removal of several heritage oaks. We suggest that the layout be altered to allow them to be retained, perhaps going to four stories in other areas of the project, especially in east-facing units with a view of Mt. Diablo. Fourth, the architectural renderings do not show details of the facades on the interior of the project. We suggest and would hope that there would be balconies facing inwards for most units. These would help activate the interior as well as provide valuable space for each unit. To the extent possible, as noted in the proposal, roof deck areas for the top units are a superior idea to balconies. Thank you for the invitation to comment on this project.

Balbas, Director Deputy Directors Stephen Kowalewski, Chief Allison Knapp Warren Lai Carrie Ricci Joe Yee Memo January 13, 2021 TO: Jennifer Cruz, Principal Planner, Department of Conservation and Development FROM: Randolf Sanders, Associate Civil Engineer, Engineering Services Division By: Deborah Preciado, Staff Engineer, Engineering Services Division SUBJECT: SUBDIVISION SD21-9559 STAFF REPORT AND RECOMMENDED CONDITIONS OF APPROVAL- REVISED (Summerhill Homes/Oak & Jones Roads/Pleasant Hill BART/APN 172-012-001, 007, 008, 020, 021, 023, 025, 026) FILE: SD21-9559 (x-ref RZ21-3258 & DP21-3001) The attached recommended conditions of approval, based on the site plan, include road and drainage requirements. The applicant shall comply with the Ordinance Code requirements as they pertain to this development. The following issues should be carefully considered with this project: Background The applicant request approval of a vesting tentative map to subdivide 8 lots, totaling approximately 5.94 acres, into 125 new residential lots for 125 town homes with two car garages in unincorporated Walnut Creek. The site, located at 2740 Jones Road, contains several existing buildings and structures and formerly known as Palmer School. The site is generally flat and extends between Jones Road and Oak Road. Interstate 680 and the BART tracks are immediately west of the site and the Pleasant Hill BART station is located 0.3 miles to the north. The Contra Costa Canal and Contra Costa Canal Trail are located approximately .1 miles south of the subject property. Traffic and Circulation The site has frontage along both Jones Road and Oak Road, both publicly maintained roads. Jones Road is a County maintained road and is constructed to its ultimate pavement width of 40 feet within a 60-foot right-of-way. The property’s frontage on Oak Road coincides with the city limit line of Walnut Creek. Oak Road has four through travel lanes and a 2-way left turn lane in the middle of the street. Jones Road has a single travel lane in each direction. Both Oak Road and Jones Road are fully developed and require no additional right of way. As proposed, the site will have 26-foot wide driveway accesses along Jones Road and Oak Road. The two driveways are connected via an internal private roadway network. The private roads Street A, Street B, Street C, and Street D are 26 feet paved within 27 feet of right-of-way. The site also includes private courts servicing the proposed condominiums. The private courts are 20 feet paved within 21 feet of right-of-way with parking stalls at the terminus of each court. The applicant shall widen the pavement width at the terminus of the private courts to 25 feet to Jennifer Cruz November 2, 2021 Page 2 of 3 accommodate local traffic turning movements. Fire turnarounds at the end of the courts are not required subject to Fire District approval. The applicant has requested an allowance for a reduced minimum curb grade of 0.6% under this application. Public Works, per Chapter 98-6.004, authorizes the reduction of the minimum uniform grade of 0.6%. The applicant is proposing to construct an internal sidewalk system to be located in the common areas of the property. For the portions of sidewalks along the private roads as shown on the development plans, the applicant shall construct a 5-foot sidewalk (measured from face of curb). Additionally, the applicant shall construct 10-foot sidewalks (measured from face of curb) along the frontage of Jones Road and Oak Road as shown on the Vesting Tentative Map. Existing driveway cuts other than the two driveway accesses shall be removed and replaced. Any cracked and displaced curb, gutter, and sidewalk shall be removed and replaced along the project frontage of Jones Road and Oak Road. Concrete shall be saw cut prior to removal. Existing lines and grade shall be maintained. New curb and gutter shall be doweled into existing improvements. Drainage Division 914 of the County Ordinance Code requires that all storm water entering and/or originating on this property to be collected and conveyed, without diversion and within an adequate storm drainage system, to an adequate natural watercourse having a definable bed and banks or to an existing adequate public storm drainage system which conveys the storm water to an adequate natural watercourse. The project site is relatively flat, sloping gently north east. Site drainage as proposed is directed to C.3 facilities and then conveyed to existing drainage lines along Jones Road and Oak Road. Prior to entering the existing the drainage is to be directed into hydromodification vaults. The existing drainage infrastructure in Jones Road and Oak Road are Line C and Line D-1 of Drainage 44B respectively. A preliminary drainage study was provided for the referenced site plan. The site drainage may have to be revised to accommodate for the treatment of the proposed private roads. Stormwater Management and Discharge Control A Stormwater Control Plan (SWCP) is required for applications that will create and/or redevelop impervious surface area exceeding 10,000 square in compliance with the County’s Stormwater Management and Discharge Control Ordinance (§1014) and the County’s Municipal Separate Storm Sewer System (MS4) National Pollutant Discharge Elimination System (NPDES) Permit. The applicant has provided a preliminary SWCP. The format of the SWCP is acceptable and deemed preliminary complete. This project alters more than 50 percent of the impervious surface of the previously existing development and is greater than 1 acre of impervious area, therefore hydromodification is required for this development. Per the SWCP exhibit the site will be divided into 34 Drainage Management Areas (DMA). Each DMA will be treated by a separate bio retention basin and flow into hydromodification vaults before discharging into storm drains in Jones Road and Oak Road. The deemed preliminarily complete, the SWCP and drainage are subject to further review and revisions. Jennifer Cruz November 2, 2021 Page 3 of 3 Provision C.10, Trash Load Reduction, of the County’s NPDES Permit requires control of trash in local waterways. To prevent or remove trash loads from municipal storm drain systems, trash capture devices shall be installed in catch basins (excludes those located within a bioretention/stormwater treatment facility). Devices must meet the County’s NPDES Permit and approved by Public Works Department. Location must be approved by Public Works Department. Floodplain Management The property does not lie within the Special Flood Hazard Area (100-year flood boundary) as designated on the Federal Emergency Management Agency Flood Insurance Rate Map. Lighting District Annexation The subject property has not been annexed into the lighting district. The property owner will be required, as a condition of approval, to annex into the Community Facilities District (CFD) 2010- 1 formed for the Countywide Street Light Financing. Area of Benefit Fee The applicant will need to comply with the requirements of the Bridge/Thoroughfare Fee Ordinance for the Central County Area of Benefit, as adopted by the Board of Supervisors. This fee shall be paid prior to issuance of building permits. Drainage Area Fee and Creek Mitigation The applicant will be required to comply with the drainage fee requirements for Drainage Area 44B as adopted by the Board of Supervisors. This fee shall be paid prior to filing of a final map. RS:DP:ss \\pw-data\grpdata\engsvc\Land Dev\SD\SD 9559_DP21-3001, RZ21-3258)\Staff Report and COAs_modified.docx cc: J.

From: M carr <manselcarr@gmail.com>   Sent: Tuesday, March 1, 2022 8:52 AM  To: Clerk of the Board <ClerkOfTheBoard@cob.cccounty.us>; Station West  <stationwesthoa@gmail.com>  Subject: COUNTY FILE CDRZ21‐03258 RESIDENTIAL DEVELOPMENT 2740 JONES RD WC    From    Mansel Carr  HOA Board President  Station West HOA             1. The Station West HOA Board & Residents concern arises from the volume of additional traffic  that will be an increase to Oak Road / Jones Rd traffic intersection and the Treat intersection. in  both directions of flow to Treat or Ygnacio Rd intersections  2. I would wish to raise the issue of traffic volume and directional flow which has been increasing  at this Jones Rd Oak Rd junction to Treat to the extent that its now impacting our residents  ability to move into traffic flow in the direction of Treat traffic flow   3. 3 the direction of low in the opposite direction to Ygnacio is nearly impossible for our residents  as the flow of stacked traffic at the Jones Rd / Oak Rd traffic lights drives will not make egress  available to that direction due the stacking of vehicles at the traffic lights  4. To better enable our residents the ability gain easier access at egress during peak traffic flow  times i would like for this hearing to know that many of our residents are aggrieved at the way  traffic flow prevent access or egress into Station West causing additional delays and potentials  for collisions clearly a health and safety issue to be considered for a solution  5. this would also impact the access by greatly restricting incoming emergency vehicles to Station  West HOA due to stacked vehicles not permitting any gaps in the stacking from the traffic light  blocking the eress & entrance to Station West a serious cause of concern our board has been  reviewing and we would like to draw to this committee's attention the need for additional traffic  planning study by Walnut Creek Councils Traffic dept for a proactive solution rather than a wait  and see approach.  6. Station West HOA Residents & Board would like to see included in this development plan the  means to enable our residents to of Station West to have a better access flow of egress and  entry to the complex from Oak Rd, buyt the installation of a car free box junction before and  after the complexes entry to enable our residents to smoothly enter  the main traffic pattern.  This is currently not the case causing the risk of collision as Station West residents enter Oak Rd  traffic in a big rush or force their way in causing issues with the Oak Rd drivers who may deem  driving with care not their priority. I have personally witnessed people come to blows because  of the no right of access to the Station West Complex from Oak Rd. At high volume hours access  is greatly restricted and is a risk to drivers in all directions.  7. The Station West Broad & residents would like for this Committee to create in the planning  review which will increase traffic volume on both sides of Oak Rd and Jones Rd that at the  Station Wests entrance to the complex the traffic free box be established enabling the in and  out flow of both ours and the new complexes residents better access than currently exists. We  do not feel any additional traffic light would help rather a solution is to place on Oak Rd at the  entrance points of both residential complexes a vehicle free no entry box to allow both sets of  residents easier in and out access and prevents the stacking back up effect of vehicles waiting at  the Oak / Jones Rd traffic light to abate to a level exiting or entering is possible. This would  reduce a lot of additional health & Safety and pollution from engines being held stationary for  longer than needed periods.   Thank you Committee, to hear our point of view for consideration of implementation as a relative cost  neutral action which traffic paint and a road sign would avail making residents access and egress issues  much improved than currently and for the future.    Yours Kindly    Mansel Carr  Station West HOA Board Chairman         RECOMMENDATION(S): 1. OPEN the public hearing on Ordinance No. 2022-09, RECEIVE testimony, and CLOSE the public hearing; 2. DETERMINE that adoption of Ordinance No. 2022-09 is exempt from the California Environmental Quality Act (CEQA) under CEQA Guidelines section 15061(b)(3) (“General Rule” exemption); 3.

ATTESTED: March 1, 2022 Monica Nino, County Administrator and Clerk of the Board of Supervisors By: June McHuen, Deputy cc: D.3 To:Board of Supervisors From:John Kopchik, Director, Conservation & Development Department Date:March 1, 2022 Contra Costa County Subject:Hearing on a Zoning Text Amendment Replacing the County's Water Conservation Ordinance with a new Water Efficient Landscapes Ordinance FISCAL IMPACT: The cost of preparing this ordinance has been funded by the Department of Conservation and Development. BACKGROUND: Senate Bill 1383 (SB 1383) was passed in September 2016 to reduce organic waste in landfills. SB 1383 Regulations (14 CCR Section 18989.2) require that a jurisdiction, which is a city, county, or a City and county, adopt an ordinance or other enforceable requirement that requires compliance with Sections 492.6(a)(3)(B) (C), (D), and (G) of the State’s Model Water Efficient Landscaping Ordinance as amended on September 15, 2015 (“MWELO SB 1383 Baseline Requirements”). Although Chapter 82-26. (Water Conservation Landscaping in New Developments), of the County’s Zoning Code regulates water use for new landscaping, department staff has been implementing the State’s Model Water Efficient Landscaping Ordinance for the past several years to comply with State water efficiency and landscaping regulations. The approval of SB 1383 in 2016 required the County and all other jurisdictions in the State to adopt an enforceable ordinance that complies with the State’s MWELO regulations. PROPOSED ZONING CODE TEXT AMENDMENT The zoning text amendment would repeal and replace Chapter 82-26 of the County Zoning Ordinance. The proposed water efficient landscape ordinance is the Model Water Efficient Landscape Ordinance (MWELO) adopted by the California Department of Water Resources and as set forth in Chapter 2.7 of Division 2, Title 23, of the California Code of Regulations, Sections 490 through 495 and Appendices A through D. The waters of the state are of limited supply and are subject to increasing demands. As such, the purpose of the State’s Model Water Efficient Landscape Ordinance is to promote the conservation and efficient use of water and to prevent the waste of this valuable resource. Changes to the existing Ordinance include the applicability of the new MWELO, landscaping documentation requirements, landscaping design plan and irrigation design plan requirements, and Certificate of Completion requirements. The proposed MWELO will apply to new construction with landscaping more than 500 square feet, rehabilitated landscape projects greater than 2,500 square feet, existing landscapes, and cemeteries. The proposed MWELO provides specific standards related to landscape design and irrigation design, irrigation and maintenance scheduling, and requirements of an irrigation audit. Further, the proposed MWELO requires a local agency to report to the State’s Department of Water Resources on the implementation of the adopted Ordinance. A project involving landscaping will be required to comply with the requirements of the MWELO. Implementation of the Ordinance requires the submittal of the required materials for the review of the Department of Conservation and Development, Community Development Division staff prior to the issuance of a building permit. The review includes ensuring the proposed landscaping and irrigation are designed appropriately so that the allowed Maximum Applied Water Allowance is not exceeded, and water use is reduced. The County General Plan Public Facilities/Services Element discusses the importance of water conservation efforts due to the droughts experienced in the region and encourages installation of drought resistance landscaping and limiting the amount of lawn areas. The MWELO is also referenced by Title 24, Part 11 CalGreen Building Code. Thus, the proposed zoning text amendment will be consistent with the goals of the County to promote conservation and efficient use of water and to prevent the waste of water. County Planning Commission Hearing The County Planning Commission held a public hearing on the draft Ordinance on January 26, 2022. The County Planning Commission opened the hearing, but received no public comment. The County Planning Commission voted 7-0 to recommend that the Board approve the proposed ordinance. Conclusion and Recommendation The purpose of the proposed text amendment is to make the County’s water efficient landscape ordinance of Contra Costa County the Model Water Efficient Landscape Ordinance adopted by the California Department of Water Resources in order to comply with SB 1383. The proposed amendments would not conflict with the Goals and Policies of the County’s General Plan and therefore, staff recommends that the Board of Supervisors adopt Ordinance No. 2022-09. CONSEQUENCE OF NEGATIVE ACTION: The existing Water Conservation Landscaping in New Developments Ordinance (Chapter 82-26) would not be amended and thus, would not be compliant with the requirements of Senate Bill 1383.

For prior histoiy, see Register 85, No. 26; 81; Nos. 40 and 38; and SO. No. 7. Chapter 2.7. Model Water Efficient Landscape Ordinance § 490. Purpose. (a) The State Legislature has found: (1) that the waters of the state are of limited supply and are subject to ever increasing demands; (2) that the continuation of California's economic prosperity is depen- dent on the availability of adequate supplies of water for fiiture uses; (3) that it is the policy of the State to promote the conservation and effi- cient use of water and to prevent the waste of this valuable resource; (4) fliat landscapes are essential to the quality of life in California by providing areas for active and passive recreation and as an enhancemCTit to the environment by cleaning air and water, preventing erosion, offer- ing fire protection, and replacing ecosystems lost to development; (5) that landscape design, installation, maintenance and management can and should be water efficient; (6) Aat Section 2 of Article X of the California Constitution specifies that (he right to use water is limited to fhe amount reasonably required for die beneficial use to be served and tfie right does not and shall not extend to waste or unreasonable method of use. (b) Consistent with the legislative findings, the purpose of this model ordinance is to: (1) promote the values and benefits oflandscq)ing practices that inte- grate and go beyond the conservation and efiBrient use of water; (2) estabUsh a structure for planning, designing, installing, maintain- ing and managing water efRcient landscapes in new construction and re- habilitated projects by encouraging the use of a watershed approach that requires cross-sector collaboration of industry, government andproper- ty owners to achieve the many benefits possible; (3) establish provisions for water management practices and water waste prevention for existing landscapes; (4) use water efficiently without waste by setting a Maximum Applied Water Allowance as an upper limit for water use and reduce water use to the lowest practical amount; (5) promote die benefits of consistent landscape ordinances with neighboring local and regional agencies; (6) encourage local agencies and water purveyors to use economic in- centives that promote the efficient use of water, such as implementing a tiered-rate stmcture; and (7) encourage local agencies to designate the necessaiy aufliority that implements and enforces the provisions of the Model Water EfHcient Landscq»e Ordinance or its local landscape ordinance. (c) Landscapes that are planned, designed, installed, managed and maintained with the watershed based approach can improve California's enviiomnenlal conditions and provide benefits and realize sustamability goals. Such landscapes will make the urban environment resilient in the face of climatic extremes. Consistent with the legislative findings and pinpose of the Ordinance, conditions in the urban setting will be un- proved by: (1) Creating (he conditions to s»q)port life in the soil by reducing com- paction, incorporating organic matter that increases water retention, and promoting productive plant growth that leads to more caifeon storage, ox- ygen production, shade, habitat and esthetic benefits. (2) Muiunizing energy use by reducing irrigation water requirements, reducing reliance on petroleum based fertilizers and pesticides, and planting climate appropriate shade trees in urban areas. (3) Conserving water by capturing and reusing rainwater and graywa- ter wherever possible and selecting climate appropriate plants that need minimal supplemental water after establishment (4) Protecting air and water quality by reducing power equipment use and landfill disposal trips, selecting recycled and locally sourced materi- Page 37 Btgiaer 2015, No. 38; 9-18-2015 §490.1 BARCLAYS CALIFORNIA CODE OF REGULATIONS Title 23 als, and using compost, mulch and efficient irrigation equipment to pre- vent erosion. (5) Protecting existing habitat and creating new habitat by choosing local native plants, climate adapted noiwutives and avoiding invasive plants. Utilizing integrated pest management with least toxic methods as (he first course of action.

(a) This section applies to landscaped areas requiring pennanent ir- rigation, not areas fliat require temporary irrigation solely for the plant establishment period. For the eflBcient use of water, an imgation system shall meet all the requiiements listed in this section and the manufactur- ers' recommendations. The irrigation system and its related components shall be planned and designed to allow for proper installation, manage- ment, amd maintenance. An irrigation design plan meeting tfae following design criteria shall be submitted as pan of the Landscape Documenta- tion Package. (1) System (A) Landscape water metere, defined as either a dedicated water ser- vice meter or private submeter, shall be installed for aU non-^esidential urigatedlandscqaes of 1,000 sq. ft. but not more Aan 5,000 sq.ft. (flielev- el at which Water Code 535 applies) and residential irrigated Imdscapes of 5,000 sq. ft. or greater. A landscape water meter may be either: I. a customer service meter dedicated to landscape use provided by the local water purveyor; or 2. a privately owned meter or submeter. (B) Automatic imgation controllers utilizing either evq»otranspira- tion or soil moisture sensor data utilizing non-volatile memory shall be required for irrigation scheduling in all irrigation systems. (C) If the water pressure is below or exceeds the recommended pres- sure of the specified irrigation devices, the inslallation of a pressure regu- lating device is required to ensure that flie dynamic pressure at each emis- sion device is within the manufecturer's recommended pressure range for optimal perfonnmce. 1. If the static pressure is above or below the required dynamic pres- sure of the irrigation system, pressure-rcgulating devices such as inline pressure regulators, booster pumps, or other devices shall be installed to meet the required dynamic pressure of the irrigation system. 2. Static waterpressure, dynamic or operating pressure, and flow read- ing of the water supply shall be measured at the point of connection. These pressure and How measurements shall be conducted at the design stage. If die measurements are not available at the design stage, (he mea- surements shall be conducted at installation. (D) Sensors (rain, fteez®, wind, etc.), either integral or auxiliary, that suspend or alter irrigation operation during unfavorable weather condi- tions shall be required on all irdgation systems, as appropriate for local climatic condBtions. Irrigation should be avoided during windy or fi^ez- ing weather or during rain. (E) Manual shut-off valves (such as a gate valve, ball valve, or butter- fly valve) shall be required, as close as possible to the point of connection of the water supply, to mmimize water loss in case of an emergency (such as a main line break) or routine repair. (F) Backflow prevention devices shall be required to protect die water supply from contamination by die imgation system. A project applicant shall refer to the applicable local agency code (i.e., public health) for additional backflow prevention requirements. (G) Flow sensors that detect high flow conditions created by system damage or malfunction are required for all on non-residential landscapes and residential landscapes of 5000 sq. ft. or larger. (H) Master shut-off valves arc required on all projects except land- scapes that make use of technologies that allow for the individual control of sprinldeis that are individually pressurized in a system equipped with low pressure shut down features. (I) The irrigation system shall be designed to prevent runoff, low head drainage, overspray, or other similar conditions where imgation water flows onto non-targeted areas, such as adjacent property, non-irrigated areas, hardscapes, roadways, or structures. (J) Relevant information from the soil management plan, such as soil type and infiltration rate, shall be utilized when designing iirigation sys- terns. (K) The design of the irrigation system shall conform to the hydro- zones of the landscape design plan. (L) The irrigation system must be designed and instaUed to meet, at a mmimum, the irrigation efficiency criteria as descnTied in Secdon 492.4 regarding the Maximum Applied Water Allowance. (M) All irrigation emission devices must meet the requirements set in the American National Standards Institute (ANSI) standaid, American Society of Agricultural and Biological Engineers'/Intemational Code Council's (ASABE/ICC) 802-2014 "Landscape Irrigation Sprinkler and Emitter Standard, All sprinkler heads installed in the landscape must doc- ument a distribution unifonnity low quarter of 0.65 or higher using Ae protocol defined in ASABMCC 802-2014. (N) It is highly recommended fliat the project applicant or local agency inquue with the local water purveyor about peak water operating de- mands (on the water supply system) or water restrictions that may impact the effectiveness of the irrigation system. (0) In mulched planting areas, the use of low volume irrigadon is re- quired to maximize water infiltration into the root zone. (P) Sprinkler heads and oflier emission devices shall have matched precipitation rates, unless otherwise directed by the manufacturer's rec- ommendations. (Q) Head to head coverage is recommended. However, sprinkler spac- ing shall be designed to achieve the highest possible distnTiution unifor- mity using the manufacturer's recommendations. (R) Swing joints or other riser-protection components are required on all risers subject to damage that are adjacent to hardscapes or inhi^i traf- file areas ofturfgrass. Rage 38.5 Regjsttr 2015, No. M; 9-18-2015 § 492.8 BARCLAYS CALIFORNIA CODE OF REGULATIONS Title 23 (S) Check valves or anri-drain valves are required on all sprinkler heads where low point drainage could occur. (T) Areas less tfaan ten (10) feet in width in any direction shall be uri- gated with subsurface irrigation or other means that produces no nmofif or overspray. (U) OveAead irrigation shall not be pennitted within 24 inches of any non-^enneable surface. Allowable imgation within the setback &om non-pemieable surfaces may include drip, drip line, or other low flow non-spray technology. The setback area may be planted or unplanted. The surfacing of the setback may be mulch, gravel, or other porous mate- rial. These restrictions may be modified if: 1. the landscape area is adjacent to permeable surfacing and no nmoff occurs; or 2. die adjacent non-yenneable surfaces are designed and constructed to drain entirely to landscaping; or 3. tfae irrigation designer specifies an alternative design or technology, as part of the Landscape Documentation Package and clearly demon- strates strict adherence to irrigation system design criteria in Section 492.7 (a)(l)(I). Prevention ofoverspray and nmoffmust be confumed during the irrigation audit. (V) Slopes greater than 25% shall not be irrigated with an urigation system with a application rate exceeding 0.75 inches per hour. This re- stricdon may be modified if the landscape designCT specifies an altema- tive design or technology, as part of the Landscape Documentation Pack- age, and clearly demonstrates no runofFor erosion will occur. Prevention ofrunoffand erosion must be confirmed during the irrigation audit. (2) Hydrozone (A) Each valve shall irrigate a hydrozone with similar site, slope, sun exposure, soil conditions, and plant materials with similar water use. (B) Sprinkler heads and other emission devices shall be selected based on what is appropriate for the plant type within that hydrozone. (C) Where feasible, trees shall be placed on separate valves from shmbs, groundcovers, and turf to facilitate the q>propriate irrigation of trees. The mature size and extent of the root zone shall be considered when designing irrigation for fee tree. (D) Individual hydrozones that mix plants of moderate and low water use, or moderate and high water use, may be allowed if: 1. plant factor calculation is based on the proportions of the respective plant water uses and their plant factor; or 2. the plant factor of the hi^ier water using plant is used for calcula- tions. (E) Individual hydrozones that mix high and low water use plants shall not be pennitted. (F) On the landscE^»e design plan and irrigation design plan, hydrozone areas shall be designated by number, letter, or other designation. On the irrigation design plan, designate the areas irrigated by each valve, and as- sign a number to each valve. Use this valve number in the Hydrozone In- fonnation Table (see Appenduc B Section A). This table can also assist with die irrigation audit and progtamming the controller. (b) The irrigation design plan, at a minimum, shall contain: (1) location and size of separate water meters for landscape; (2) location, type and size of all components of the irrigation system, including controllers, main and lateral lines, valves, sprinlder heads, moisture sensing devices, rain switches, qiuck couplers, pressure regula- tors, and backflow prevention devices; (3) static water pressure at the point of connection to the public water supply; (4) flow rate (gallons per minute), application rate (inches per hour), and design operating pressure ^pressure per square inch) for each station; (5) recycled water irrigation systems as specified in Section 492.14; (6) the following statement: "I have complied with the criteria of the ordinance and applied them accordingly for the efficient use of water in the irrigation design plan"; and (7) the signature of a licensed landscape architect, certified irrigation designer, licensed landscape contractor, or any other person authorized to design an irrigation system.

FISCAL IMPACT: No fiscal impact. BACKGROUND: The Vision Zero Action Plan demonstrates Contra Costa County's commitment to Vision Zero: the elimination of severe injuries and fatalities resulting from traffic collisions on County roadways. The purpose of Contra Costa County’s Vision Zero Action Plan is to identify opportunities for safety for all modes through implementation of a Safe System approach. This builds upon the engineering-focused Systemic Safety Analysis Report (SSAR) to provide a comprehensive, multidisciplinary, and holistic approach to safety. The Vision Zero Final Report summarizes and documents the County’s Vision Zero Action Plan. Between the study years of 2014 and 2018, 2,256 collisions occurred in unincorporated Contra Costa County that resulted in injuries of any severity. The number of annual collisions increased by 18% during this period, with collisions resulting in someone being killed or severely injured (KSI) reaching a peak in 2018, which is the last year in which data was collected for the Vision Zero Final Report. The engineering-focused recommendations in the SSAR are a key step forward in curbing the rise in KSI collisions. The Final Report also identifies a High Injury Network (HIN) for the County, establishing a framework for the development of 11 collision profiles and 35 project locations. The resulting ten priority projects were selected from the project locations list by studying the collision data, collision factors, and incorporating feedback from the community (via an interactive webmap).

Balbas, Public Works Director/Chief Engineer Date:March 1, 2022 Contra Costa County Subject:Contra Costa County Vision Zero Final Report and Vision Zero Action Plan, Countywide. BACKGROUND: (CONT'D) While the priority projects focus on infrastructure improvements, the Final Report also discusses infrastructure recommendations, including road users, safe speeds, post-crash care, equity considerations, and emerging technologies. The Safe System approach understands that humans make mistakes and are vulnerable, but the responsibility is shared, safety is proactive, and redundancy is crucial. The Vision Zero Action Plan aims to support a safety culture that includes education and engagement, cross-sector partnerships, emergency response and post-crash care, emerging technology implementation, and data collection and management. The goal of Vision Zero is the ultimate elimination of fatalities and severe injuries on County roadways through the continuation of existing efforts and programs, along with implementation of the additional recommendations outlined in the Action Plan. Many municipalities locally, nationally, and worldwide, such as San Francisco and the City of Fremont, have adopted a Vision Zero program. The County began this effort to create an Action Plan, in response to a spike in fatalities on County roads occurring between 2015 and 2017. The Contra Costa Transportation Authority (CCTA) is also concurrently developing a Vision Zero framework on a higher level, whereas the County’s Vision Zero Action Plan focuses on unincorporated roadways. Adoption of the Vision Zero Final Report and Action Plan will also qualify as the County’s requirement for the Local Road Safety Program (LRSP) that all municipalities in California are required to fulfill in order to receive One Bay Area Grant (OBAG) and Highway Safety Improvement Program (HSIP) grant funding. The County’s Vision Zero Final Report and Action Plan was prepared by transportation engineering consultant Fehr & Peers, under the direction of the Public Works Department. As part of this effort, the team launched a Technical Advisory Committee (TAC), made up of representatives of the Department of Conservation and Development, County Public Health, the California Highway Patrol, CCTA, 511 Contra Costa, and bicycle advocates. This TAC met four times over the course of six months. The TAC produced two documents that were incorporated into the final Plan. The Systemic Safety Analysis Report (SSAR) laid out the framework for where, when, and how crashes are occurring on unincorporated County roadways. This document was finalized and accepted by the California State Department of Transportation (Caltrans). The SSAR is a more “engineering-focused” document, and while the Vision Zero Final Report contains some of the same technical information as the SSAR, it is more expansive in nature. It builds upon the the SSAR to include a more holistic approach to roadway safety for non-engineering partners, such as County Public Health, Law Enforcement, advocacy groups, and County Planning. The Contra Costa County’s Vision Zero Action Plan and Final Report is the culmination of four years’ effort to improve safety on the public roads in the unincorporated areas of Contra Costa County. On November 8, 2021, the Transportation Water and Infrastructure Committee (TWIC) accepted the draft of the Final Vision Zero Report, dated October 2021, and directed Public Works staff to incorporate comments and present to the full Board of Supervisors for adoption. Key Takeaways From 2014 to 2018, there were 252 collisions that resulted in people being killed or severely injured (KSI) on Contra Costa County roads (county-owned and maintained non-freeways), and the total number of collisions resulting in injuries increased by 18%. Of all these collisions, 70% occurred on the High Injury Network (HIN), which makes up only 22% of roadway miles. 1. Pedestrian- and bicycle-involved collisions account for a disproportionate share of KSI collisions relative to their travel mode share.2. Eleven systemic safety profiles highlight the most common, severe, and noteworthy collision patterns in the County. Those with the most associated KSIs include the following: 3. Driving Under the Influence Vehicles Crossing into Opposing Lanes on Rural Roads Roadway Departure Collisions on Rural Roads Collisions at Signalized Intersections of Major (5+ Lanes) and Minor (3 Lanes or Fewer) Streets Bicycle-Involved Collisions along Rural Roadways where Bicycle Facilities Do Not Exist From these 11 systemic profiles, 35 projects have been recommended Countywide, with 10 identified as priorities. The projects address critical gaps in pedestrian and bicycle facilities, gateway locations at the rural/suburban edge (some of the busiest intersections in the County), and many locations with opportunities to work with partnering agencies and organizations. 4. Following the Safe System approach, non-engineering countermeasures have also been identified to address the systemic profiles, including media campaigns, school and community partnerships, data-driven enforcement, post-crash care, and monitoring and evaluation. 5. Eight of the twelve actions were identified for cross-departmental collaboration that focus on implementation, monitoring, and accountability in support of the Vision Zero goal. This list of actions is envisioned to be refreshed on a periodic basis, as necessary, to support sustained progress. 6. Guiding Principles As an equity-focused and community data-driven initiative to proactively implement multimodal transportation safety improvements, this Vision Zero Plan aims to eliminate fatal and severe injuries throughout unincorporated Contra Costa County by 2035. Key elements of this approach include the following: Safety is the highest priority: Motor vehicle collisions should not result in a fatality or serious injury on County roadways. They are preventable and unacceptable incidents. 1. People make mistakes: Errant driver behavior will be taken into consideration for design, construction, operation, and continuous evaluation of roads to determine the impact of such driver behavior on the most vulnerable road users. 2. Safety is a shared responsibility: The goal is to create a roadway system where users, roadway designers, law enforcement, and post-crash care cohesively reinforce safety. 3. A data-driven approach: Ongoing evaluation should continue to identify where and why traffic collisions are occurring and prioritize projects and programs that eliminate fatal and severe collisions. Proactive and reactive data-driven engineering decisions have been and will be made to design and manage roadways to reduce the severity of collisions. 4. Transportation networks must be equitable: The transportation networks in unincorporated Contra Costa County must be equitable to all road users and serve all ages and abilities. Equity Priority Communities will be considered as projects are developed. New safety interventions will not worsen equity concerns, especially as it relates to enforcement. 5. Vision Zero will be accountable and transparent: Evaluation through an equity lens will be ongoing. The County strives to be transparent in its communications on roadway designs, prioritizing competing improvements, and use of resources needed to reduce fatal and severe collisions on County roadways. 6. CONSEQUENCE OF NEGATIVE ACTION: Failure to adopt the Vision Zero Final Report will disqualify the County from receiving Highway Safety Improvement Program (HSIP) and One Bay Area Grant (OBAG) funding due to the State’s requirement that each jurisdiction adopt a Local Roadway Safety Plan (LRSP), or equivalent, such as a Vision Zero Plan.

EXECUTIVE SUMMARY 6 Contra Costa County Vision Zero Action Plan From 2014 to 2018, there were 252 collisions that resulted in people being killed or severely injured (KSI) on Contra Costa County roads (County-owned and maintained non-freeways), and the total number of collisions resulting in injuries increased by 18%. Of all these collisions, 70% occurred on the High Injury Network (HIN), which makes up only 22% of roadway miles. 1 Pedestrian- and bicycle-involved collisions account for a disproportionate share of KSI collisions relative to their travel mode share. Persons of color are also disproportionately involved in collisions relative to their share of the County population.2 Eleven systemic safety profiles highlight the most common, severe, and noteworthy collision patterns in the County. Examples of these systemic profiles include: • Driving Under the Influence • Bicycle-Involved Broadside Collisions at Urban Intersections • Roadway Departure Collisions on Rural Roads • Pedestrian Crossing Urban Roadways Midblock Outside Marked Crosswalks • Bicycle-Involved Collisions along Rural Roadways where Bicycle Facilities Do Not Exist 3 4 From these 11 systemic profiles, 35 projects have been recommended Countywide, with 10 identified as priorities. The projects address critical gaps in pedestrian and bicycle facilities, enhance gateway locations at the rural/suburban edge, and include opportunities for partnerships with neighboring jurisdictions on regionally-significant projects. Following the Safe System approach, non-engineering countermeasures have also been identified to address the systemic profiles, including media campaigns, school and community partnerships, data-driven enforcement, post-crash care, and monitoring and evaluation. Eight of the twelve actions were identified for cross-departmental collaboration that focus on implementation, monitoring, and accountability in support of the Vision Zero goal. This list of actions is envisioned to be refreshed and re-evaluated on a periodic basis, as necessary, to support sustained progress. 5 6 Key Takeaways 7Contra Costa County Vision Zero Action Plan 8 Contra Costa County Vision Zero Action Plan 18 22 40 Chapter 2: Vision and Guiding Principles Chapter 3: Collision History, Risk Factors, and Trends Chapter 4: Countermeasures 58 74 80 Chapter 5: Project Development Chapter 6: Safety Efforts and Programs Chapter 7: Funding 10 Chapter 1: Introduction TABLE OF CONTENTS 88 Chapter 8: Vision Zero Core Elements and the Action Plan 9Contra Costa County Vision Zero Action Plan CHAPTER 1 10 Contra Costa County Vision Zero Action Plan INTRODUCTION 11Contra Costa County Vision Zero Action Plan A pedestrian with a dog using an enhanced crosswalk to cross Danville Blvd in Alamo 12 Contra Costa County Vision Zero Action Plan 1 Belin, M.-Å., Tillgren, P., & Vedung, E.

This section defines the Safe System approach and explains the philosophy underpinning this Vision Zero plan. People are killed and seriously injured each day on roads in California and across the U.S. On average, a KSI collision occurs on County roadways once every week. Crashes can irreversibly change the course of human lives, touching victims, their families and loved ones, and society as a whole. Contra Costa County believes all KSIs are unacceptable and is adopting a Safe System approach to improve safety on county roadways. Through collective action on the part of all roadway system stakeholders— from system operators and vehicle manufacturers to law enforcement and everyday users—a Safe System approach anticipates human mistakes with the goal of eliminating fatal and serious injuries for all road users.1 A Safe System acknowledges the vulnerability of the human body when designing and operating a transportation network, in terms of the amount of kinetic energy transfer a body can withstand. According to the World Health Organization, the goal of a Safe System is to ensure that if crashes occur, they “do not 13Contra Costa County Vision Zero Action Plan result in serious human injury.”2 A Safe System approach addresses the five elements of a safe transportation system— safe road users, safe vehicles, safe speeds, safe roads, and post-crash care—in an integrated manner and through a wide range of interventions (see Figure 1). The Safe System approach to road safety started internationally as part of the Vision Zero proclamation that no one should be killed or seriously injured on the road system.3 Countries adopting the Safe System approach have 2 World Health Organization (2011).

The County is primarily suburban and is home to approximately 1,153,600 people.5 Contra Costa County is broadly divided into three sub- regions, and the unincorporated areas include the following communities: • West County — Kensington, El Sobrante, North Richmond, Rodeo, Crockett, Port Costa, Bayview- Montalvin, East Richmond Heights, Rollingwood, Tara Hills • Central County — Canyon, Pacheco, Vine Hill, Clyde, Contra Costa Centre (Pleasant Hill BART station), Saranap, Alamo, Blackhawk, Tassajara, Briones, Diablo, Mountain View • East County — Bay Point, Bethel Island, Knightsen, Discovery Bay, Byron The County’s most notable landmark is Mount Diablo, but the County is also well known for its many trails and recreational facilities, including Acalanes Ridge, the Bay Trail, Briones Regional Park, Las Trampas Regional Wilderness, and the Carquinez Strait Regional Shoreline. A majority of the existing roadway network was built with a focus on motor vehicles. Multimodal traffic safety is a growing concern because of the suburban land use patterns in the County, major freeways running through the unincorporated areas, nearby recreational uses, and development occurring throughout the County. 5 Census Bureau American Community Survey (ACS) 2019 1-year estimates. Pedestrian- and bicycle- involved collisions have seen an upward trend in recent years. Historic auto-oriented land use patterns and a focus on reducing vehicle delay/ congestion over multimodal accessibility and comfort have led to environments throughout the County where walking and bicycling are uncomfortable and safety concerns have arisen. To that end, this plan focuses on holistic interventions to decrease KSI collisions on County-maintained roadways. For demographic context, the County’s total population is 42% White, 18% Asian, 9% Black or African American, 26% Hispanic or Latinx, 0.2% Native Hawaiian and Other Pacific Islander, 0.3% American Indian and Alaskan Native, and 5% of another race or of two or more races. 16 Contra Costa County Vision Zero Action Plan 3101 3101 ·123 ·160·242 ·24 ·4!"80 %&580 %&680 C:\CCC_VZ\basemap\Project_Locations.mxdCountywide High Injury Network and KSI Collisions Figure 2 Regions and Communities in Unincorporated Contra Costa County 17Contra Costa County Vision Zero Action Plan North Richmond Kensington East Richmond Heights Rollingwood El Soberante Tara Hills Bayview-Montalvin Rodeo Crockett Port Costa Saranap Contra Costa Centre Canyon Briones Pacheco Vine Hill Alamo Blackhawk Tassajara Diablo Clyde Mountain View Bay Point Discovery Bay Bethel Island Byron Knightsen West County Communities Central County Communities East County Communities CHAPTER 2 18 Contra Costa County Vision Zero Action Plan VISION AND GUIDING PRINCIPLES 19Contra Costa County Vision Zero Action Plan Vision Statement Contra Costa County will have an equitable, sustainable, multimodal transportation system where users of all ages and abilities can travel conveniently, reliably, and free from harm.

Five years of the most current crash data available at the time (2014-2018) were extracted from the Statewide Integrated Traffic Records System (SWITRS) and Transportation Injury Mapping System (TIMS) databases. The datasets include extensive collision detail, such as collision location, type, severity, parties involved, contributing factors, and more. The SSAR provides an in-depth analysis of this crash history data, identifying collision trends, location types, and hot spots for crashes resulting in a death or serious injury. This Vision Zero Report includes key highlights from that effort. Collisions on freeways and other roadways not maintained by the County, within city limits, or on private property were not included in this study.7 7 The exception is the surface section of State Route 4 from the intersection of Marsh Creek Road and Vasco Road eastward to the county line; collisions on this segment were included for analysis in this study. 24 Contra Costa County Vision Zero Action Plan Pedestrians at the Pleasant Hill/Contra Costa Centre BART Station 25Contra Costa County Vision Zero Action Plan Annual Collision Trends Annual collision trends show a rise in collisions since 2014. The total number of collisions across all modes rose from 413 in 2014 to 486 in 2018. Fatal and severe injury (KSI) collisions dipped in 2016, but show an upward trajectory. Fatal collisions peaked in 2015 and 2018, with 17 and 19 fatalities, respectively. Motor vehicle KSI collisions experienced a dip in 2016 but have increased since then. Bicycle-involved KSI collisions decreased from 2015 to 2016, remained constant between 2016 and 2017, and peaked in 2018 with eight KSI collisions. Pedestrian-involved KSI collisions saw a spike between 2016 and 2017, with KSI collisions jumping from four in 2016 to ten in 2017. Pedestrian and bicycle- involved collisions account for 23% of all KSI collisions. 0 10 20 30 40 50 60 70 80 2014 2015 2016 2017 2018Collisions Year Motor Vehicle Bicycle Pedestrian Figure 3 KSI Collisions by Year and Mode Source: Contra Costa County Systemic Safety Analysis Report (February 2021) 26 Contra Costa County Vision Zero Action Plan Collision Severity Vulnerable road users, including bicyclists and pedestrians, are more susceptible to fatal or severe injury collisions. In terms of collision mode, pedestrian- involved collisions led to the highest percentage of KSI collisions at 30%, with 10% of those collisions being fatal.

The HIN accounts for 143 miles of roadways, representing 22% of the 662 miles of roadways maintained by the County. A total of 2,174 non-freeway collisions occurred in the study area between 2014 and 2018; the HIN captures 70% (or 1,528) of these collisions. A total of 252 of the 2,174 non- freeway collisions were KSIs; the HIN captures 73% (or 184) of these collisions. Pedestrian using a push button 37Contra Costa County Vision Zero Action Plan Contextual Data and Systemic Analysis A systemic analysis looks at crash history on an aggregate basis to identify high-risk roadway characteristics in locations that have not necessarily seen a high number of collisions. This approach allows the County to proactively apply for grant funding at high-risk locations and carry out safety investments and widespread implementation of projects to reduce potential severe and fatal collisions at these locations. The systemic analysis in the SSAR combined crash history and contextual data—including roadway characteristics and the characteristics of the surrounding areas—in addition to input and comments from County staff and Technical Advisory Committee (TAC) members to produce a set of 11 collision profiles that highlight the most common, severe, and noteworthy collision patterns in the County, which are listed in the table on the facing page along with the number of KSI collisions that align with each respective profile. They are grouped into the primary mode with which they are associated: bicycles, pedestrians, and automobiles only. Countermeasures were identified for specific location contexts for each of the 11 collision profiles. These profiles were also linked with the engineering-based projects outlined in the SSAR.

The countermeasures recommended by the SSAR for the various profiles and locations around the County are presented on the facing page, and detailed information for each can be found in the appendix of the SSAR. These countermeasures focus on separating users in space and time to reduce conflicting movements, improving visibility for all users, and reducing kinetic energy transfer in the event of collisions. Safe Road Users Safe Speeds Post-Crash Care EmergingTechnologies EquityConsiderations Non-Engineering Countermeasures The following sections present additional safety countermeasures to include Road Users and Post-Crash Care, supplementing the SSAR’s engineering-focused countermeasures on roadway design and speed reductions. Vehicle design does not fall within the County’s purview, though opportunities to consider autonomous vehicle planning and intelligent transportation system technologies with future safety efforts are acknowledged. These non-engineering countermeasures are organized into five categories, as shown on the right. 43Contra Costa County Vision Zero Action Plan Transportation safety education plays an important role in shaping and shifting behavior. Many cities such as Seattle, Oakland, and Los Angeles are increasing community engagement and education to make streets safer for all. For example, the Los Angeles Vision Zero Dignity-Infused Community Engagement (DICE) approach includes partnerships with local nonprofits, paid outreach work for those experiencing barriers to employment, and both large- and small-scale community engagement events. Public Education Media Campaign A public education media campaign focused on discouraging drinking and driving and/or speeding would complement engineering interventions targeting these risk factors in the County. Campaigns should also include the encouragement of increased awareness of pedestrians and bicyclists at night and appropriate crosswalk behaviors. Targeted education, such as on buses and bus shelters, on billboards, at movie theaters, or on local radio stations, may be directed at vulnerable populations with the help of local partners, and at certain behaviors of drivers, pedestrians, and bicyclists to deter specific collision types. Specific locations on the high-injury network, as well as partner campaigns with the County’s Public Health Services Safe Routes to School team, may also be appropriate for concentrated educational messages. The County will consider joint efforts with Contra Costa Transportation Authority (CCTA) to develop outreach education campaigns focusing on common violations leading to fatalities and severe injuries, based on the collision profiles identified in the SSAR. Education and outreach campaigns could target the following: • Reducing driving under the influence, as 29% of KSI collisions involved drugs or alcohol. • Providing education around driver behavior, as 33% of motor vehicle KSI collisions were caused by improper turning; the top violations for bicycle-involved KSI collisions were unsafe speeds and improper turning (both 28%). • Encouraging pedestrians to cross in crosswalks and drivers to yield to pedestrians, to complement engineering countermeasures addressing the need for safer crossings, as 39% of KSI collisions were pedestrian violations and 18% of KSI collisions were pedestrian right-of-way violations. Safe Road Users 44 Contra Costa County Vision Zero Action Plan Partner with Local Experts Local partners should serve as community liaisons between the County and the public. Working with community partners and public institutions that have relationships with residents, such as local libraries, churches, cultural organizations, Boy and Girl Scouts, school safety patrol, and the Boys and Girls Clubs of Contra Costa, strengthens the engagement process by building trust and drawing on an established base of stakeholders. Local partners could help tailor the engagement process or incorporate engagement into existing programs and resources to educate people more effectively about roadway safety. Partner with Local Schools on Transportation Safety The County could partner with local schools to promote safe driver behavior. Education campaigns could involve students promoting safer driving to their parents by holding signs during pick-ups and drop-offs. Expanding existing youth programs led by the County’s Health Services presents an opportunity to provide ongoing Safe Routes to School education to all students each year. Schools throughout the County have also used various educational programs such as the Street Smarts Program and the California Highway Patrol’s (CHP) Start Smart Program that high schools use as an educational driving program that is required before a student is able to receive a parking permit. Office of Traffic Safety (OTS) grants also offer a variety of education programs intended to teach high school students about the dangers of alcohol and driving, including Every 15 Minutes, Sober Graduation, and DUI mock trials. Educational Materials on New Roadway Design Changes Temporary demonstrations, like pop-up installations, can physically showcase proposed safety infrastructure and emergency response to the public in a tangible way. Using social media platforms such as NextDoor to prepare and promote materials and videos focused on new types of roadway designs and the County’s major violation issues could direct community conversations for meaningful outcomes. 45Contra Costa County Vision Zero Action Plan The goal of high-visibility enforcement is to promote voluntary compliance with traffic laws and, according to National Highway Traffic Safety Administration (NHTSA) research, it is one of the most effective enforcement strategies for safety outcomes.9 Roadway networks within the County should address the safety of all road users, including those who walk, bike, roll, drive, and ride transit. Roadway design and management should encourage safe speeds, separate users in space and time, reduce kinetic energy transfer, and manipulate crash angles to ensure that collisions do not result in a fatality or serious injury. The SSAR provides engineering design recommendations for traffic calming such as lane narrowing, road diets, advanced yield and stop markings, and speed feedback signs, but these improvements should be complemented with enforcement tactics.

Accessed May 3, 2021. High-Visibility Enforcement High-visibility enforcement is a multifaceted approach to enforcement that garners public attention to traffic safety laws through highly visible patrols, such as checkpoints, saturation patrols, or message boards. OTS provides three grant funding sources to supplement CHP in their high-visibility enforcement goals. The goal for Get Education and Ride Safe III (GEARS III) is to reduce the number of motorcycle-involved KSI collisions. The goal of the Safer Highways Statewide grant is to reduce the number of alcohol-involved KSI collisions. Lastly, the Regulate Aggressive Driving and Reduce Speed V (RADARS V) grant is aimed at reducing the number of victims killed or injured due to speed, improper turning, driving on the wrong side of the road, or reckless driving-related collisions. 46 Contra Costa County Vision Zero Action Plan Automated Enforcement Automated enforcement methods, such as red- light cameras or speed safety cameras, equitably target the specific drivers who are behaving dangerously. A strictly data-driven approach to automated enforcement might place red-light or speed cameras in locations with the highest number of collisions; however, speed safety cameras are not currently allowed in California. The County should monitor potential changes to state legislation for future use of this critical tool, should it become available. Cross-Sector Partnerships Alternatives to law enforcement involve investing in cross-sector partnerships to promote transportation safety. Partnerships for the County’s consideration include: • Hiring community partners as Street Safety Ambassadors to canvas corridors with severe traffic fatalities or where communities are experiencing the most traffic stops or tickets for traffic violations. Hiring community members as Street Safety Ambassadors would also serve as an opportunity to build trust between government agencies and the public, since community partners typically have pre-existing relationships in the community. • Hiring social workers, mental health counselors, addiction specialists, and other unarmed, specially trained professionals can supplement traffic enforcement. Partnering with local departments of mental health and public health may de-escalate traffic enforcement by treating traffic safety violations as a public safety issue. 47Contra Costa County Vision Zero Action Plan Post-Crash Care Post-crash care is more than just medical care. It also includes the training of personnel and design of emergency vehicles and roadway infrastructure. Post-crash care also includes providing additional resources to the victims and their families such as resources for physical and mental rehabilitation, including support from organizations such as Families for Safe Streets. Emergency Medical Services Response Victims involved in a collision have a higher chance of survival if they can quickly receive medical care. In many cases, law enforcement officers and fire department staff are the first responders to arrive at a collision location. In addition to equipping all first responders with the appropriate training, improving response times for EMS would help improve the chance of survival for collision victims. Collisions can also put the lives of first responders and other road users at risk due to increased congestion during the crash response, which may lead to secondary crashes. The County could work with EMS to improve response times and ensure safety in both arriving at and attending to patients at the scene. Strategies include designing emergency vehicles to be highly visible (e.g., retroreflective striping and chevrons, high-visibility paint, and built-in passive light) and implementing emergency vehicle signal preemption, which allows emergency vehicles to break a normal signal cycle and proceed through an intersection. 48 Contra Costa County Vision Zero Action Plan Bike infrastructure along San Pablo Dam Road 49Contra Costa County Vision Zero Action Plan Trauma Care Effective emergency trauma care can increase crash survival rates by as much as 25%, and an effective trauma care coordination system can reduce fatalities by 50%.10 Contra Costa County could work with EMS and identify funding sources to improve on their existing infrastructure to be able to provide the highest care for victims. Recommended strategies to improve trauma care include providing funding for appropriate first responder equipment (e.g., hydraulic and pneumatic extrication tools), research for and adoption of technology aimed at reducing triage time (e.g., automatic vehicle reporting of severe crashes to EMS, EMS vehicle collision avoidance systems, and geolocation of nearest EMS vehicles), and promotion of federal- and state-certified training programs. Fatal Crash Response Team In the event of a traffic fatality, analysis and evaluation are crucial in addressing the burden of traffic mortality and tracking progress toward eliminating fatalities on County roadways. One strategy would be for a designated person at the County to notify a cross-agency group after each fatal crash, including law enforcement, transportation officials, and public health officials. This would assist with accurate investigation and documentation of potentially relevant infrastructural and environmental crash factors, while identifying other additional factors that may have contributed to the fatal crash outcome. It can also expedite interventions to improve the crash location/circumstances and address similar risk factor locations and situations. Post-Crash Care 10 Office of Traffic Safety (OTS) (2020).

Pg. 106. 50 Contra Costa County Vision Zero Action Plan Policy, Practices and Additional Resources When individuals are injured in collisions, they rely on emergency first responders to quickly locate them, stabilize their injuries, and transport them to medical facilities. Post-crash care also includes forensic analysis at the crash site and traffic incident management, so that traffic flow may be restored as safely and quickly as possible. Policy action through the justice system and appropriate design of roadways to lessen the risk of future crashes can also help inform our safety programs. Crash reporting practices, such as complete data collection and documentation of road user behavior and infrastructure, and sharing data across agencies or organizations (e.g., law enforcement, health officials, transportation officials, and hospitals) can help lead to a greater understanding of the holistic safety landscape, and thus lead to improved investments in safety. To ensure a crash survivor receives the care needed to recover and restore body and mind to an active life within society, they require medical rehabilitation with specialists that can range from orthopedics, neurosurgery, physical and occupational therapy, and prosthetics to psychology and neuropsychology. Resources for crash survivors, their family, and friends, can be found on Contra Costa Health Services’ website, https://cchealth.org/mentalhealth. Severe and fatal collisions not only affect the victim involved, but their family and friends as well. Across the nation, in Canada, and locally in the San Francisco Bay Area, there are chapters of Families for Safe Streets. This group advocates at the state capitol in Sacramento and works with lawmakers and non-profits like Mothers Against Drunk Driving to share their stories and testify before legislative committees. Supporting victims’ families can come in many forms. World Day of Remembrance for Road Traffic Victims is an annual event held on the third Sunday in November in remembrance of those who have died or have been affected by motor vehicle collisions, and to draw attention to the goal of Vision Zero. 51Contra Costa County Vision Zero Action Plan Creating an equitable framework for all modes of transportation in the County and removing transportation barriers for historically marginalized communities, especially communities of color, should ensure safe and fair transportation options so that all road users have a safe route and access to basic community services. The County will proactively work to address the inequities built into the current transportation system to keep vulnerable members of the community safe.11 Funding and Project Prioritization Ten priority engineering projects were identified and prioritized based on their perceived competitiveness for grant funding and alignment with County priorities, and were ranked by priority by the community. The County can apply for grant funding opportunities, such as California’s Active Transportation Program, prioritize projects that increase safety and travel options for people walking and bicycling, and ensure that disadvantaged communities fully benefit from the ATP. California Office of Environmental Health Hazard Assessment’s (OEHHA) CalEnviroScreen and the Metropolitan Transportation Commission’s (MTC) Equity Priority Communities scores show part of Contra Costa County within the 25% most disadvantaged areas, making these priority areas for state and local funding opportunities. EquityConsiderations Culturally- Relevant Engagement Community engagement is not a one-size-fits-all model, as different communities have different needs. By developing culturally relevant engagement strategies that would be available on the County’s website, participants would feel welcomed to participate in conversations about safety. Culturally relevant engagement strategies help education and programming around traffic safety reach a larger audience and be more impactful. For example, including cultural markers of a local community, such as contracting with popular local food vendors to cater engagement activities, may be a creative and welcoming way to engage residents. Meeting people “where they are” to gather input on safety issues at local parks can more effectively engage parents and children, rather than expecting families to attend a meeting at a government building. 11 FHWA (2018).

Accessed May 3, 2021. 52 Contra Costa County Vision Zero Action Plan Traffic Enforcement Through statistical analysis (traffic volumes, collision data, speed surveys, etc.) and observations and concerns received from citizens and key stakeholders regarding safety, the CHP is dedicated to reducing collisions through preventative enforcement based on data-driven concerns and locations. Some agencies are shifting enforcement efforts to equity-based strategies that target specific reckless behaviors posing the highest safety risk while working to mitigate potential inequities in enforcement. Other agencies are looking for opportunities for non-sworn officers to be engaged in transportation enforcement activities, as appropriate. Equity can also be considered in a range of enforcement strategies, including progressive fine structures, analysis of demographic data in traffic citations, community- based alternatives to police enforcement, and investment in social programs that alleviate enforcement burdens. Currently, fine structures, including any proposed changes and base fines for most offenses when a bill becomes law, is set by the State Legislature and not CHP. Additional fines, fees, and penalties are assessed by local counties and the State. CHP should update the County of any changes in implementing any of these suggested equitable enforcement strategies: • Progressive traffic fine structures, such as a sliding scale based on a driver’s income, development of payment plans, or the opportunity for first offenders to take a safety class focusing on driver behavior changes may be considered. • The analysis of available demographic data and the location of traffic citation would help the County understand if traffic enforcement is being implemented universally or if specific communities are experiencing disparities in enforcement. • Assessment of traffic citation demographics and geographic data would help uncover inequities in policing and the enforcement of traffic safety. 53Contra Costa County Vision Zero Action Plan EmergingTechnologies features and technologies (e.g., along key roadways and intersections) to better understand and monitor risk scenarios in partnership with CCTA. • Public crowdsourcing — Online web crowdsourcing platforms, such as UC Berkeley’s SafeTREC Street Story tool (available in English and Spanish), allow anyone to anecdotally report incidents of near misses: https://safetrec.berkeley.edu/ tools/street-story-platform- community-engagement These data points are publicly available for analysis and contain important contextual information based on geographic location (e.g., road conditions, street lighting, and travel mode). Using a platform like Street Story in future projects could also advance community education and engagement around road safety by providing an outlet and way for people to connect around each other’s stories. collection technologies are reducing that limitation. The County could consider using examples of surrogate safety measure technologies to help close the gap and provide key safety insights including the following: • Video data — Video machine learning is an effective means of classifying collisions and collecting near-miss and hard breaking data. Data vendors, such as StreetLight Data, have partnered with Ford Motors to combine multiple datasets, including connected vehicle data, to provide information such as hard braking data. This information can provide the County with a deeper understanding of hotspots where motorists need to brake hard to avoid a collision between a pedestrian, bicyclist, or other vehicle. CCTA has purchased StreetLight Data, and the County could consider investing in additional Recent advancements in transportation technology have not only introduced new transportation modes and travel patterns but have also presented opportunities to better understand travel behavior and encourage safe behavior. Crash Risk Indicators Surrogate safety measures, such as “near-miss” collisions, hard braking data, community- reported hazards, and high stress facilities, can provide a fuller understanding of the safety landscape and enable proactive interventions. “Near misses” have historically been difficult to study in practical safety applications due to an overall lack of reported information; however, new data 54 Contra Costa County Vision Zero Action Plan Data Collection, Inventory, and Management Up-to-date data on transportation infrastructure, including roadway characteristics, intersection characteristics, and signs, are valuable for planning and implementing future improvements. With an updated inventory, the County could also allow for the identification of project synergies, such as including a safety countermeasure with a repaving project. Finally, enhanced contextual data supports systemic safety analysis for future safety plans and evaluations. Examples of service providers available to assist with this work include the following: • Mapillary uses crowdsourced or privately provided street-level imagery to extract and map signs, streetlamps, sidewalks, signals, and other objects: https://www. mapillary.com/ • Ecopia uses satellite imagery to extract features such as road centerlines, roadway cross-sections, sidewalks, and more: https://www.ecopiatech.com/ Emerging Vehicle Technologies Safe vehicles are another element of the Safe System approach, and will increasingly add more redundancy or avoidance features in the system. Leveraging connected and autonomous vehicle (CAV) technology and identifying crash-avoidance systems with vehicle manufacturers is key in ensuring vehicles are safe for all road users in the future. The County does not currently design vehicles, but could take policy and design of County roadways into consideration as vehicle technology advances. Connected Systems and Vehicles Smart signal technology enables agencies to collect data at multiple intersections, providing a high- resolution understanding of how people are using the roadway in real time. Connected vehicles are another part of this system. They wirelessly communicate with other vehicles and infrastructure (like signals) to provide data for instantaneous decision-making (e.g., reporting driver speed or collisions). Data from signals in combination with data from vehicles could allow the County to deploy real time speed-related signal operations, allowing for enhanced safety through adaptable systems. The County should consider upgrades to infrastructure as connected systems and vehicle technology advance. 55Contra Costa County Vision Zero Action Plan DUI Strategies and Considerations The “Collision History, Risk Factors, and Trends” chapter of this report includes the 11 collision profiles from the SSAR that highlight the most common and severe collision patterns on unincorporated County roadways. Safe road users, safe speeds, and safe roads elements can complement the engineering countermeasures listed in the SSAR for all 11 emphasis areas. One profile, driving under the influence (DUI), is a major factor in fatal and severe collisions in the County that will require a full Safe System approach to address. In addition to engineering-focused countermeasures, DUI collisions also require non-infrastructure prevention programs. The County is committed to implementing policy to reduce the rates of driving under the influence. These policies generally fall under three categories: 1. Deterrence policies focus on raising the actual and perceived risk of detection of driving under the influence. These policies should be highly visible to increase awareness of the risks of driving under the influence. Publicized sobriety checkpoints, saturation patrols, and other forms of high-visibility enforcement are effective for safety outcomes. 2. Prevention and education policies focus on mobilizing and educating the community and intervening before driving under the influence takes place. According to NHTSA research, alcohol problem assessment and treatment programs, as well as alcohol intervention in settings such as a doctor’s office, are highly effective strategies for improving safety outcomes.12 3. Limited access policies focus on making underage access to alcohol and drugs more difficult, and seek to limit excessive alcohol consumption. Increasing funding for efforts that focus on prevention and education, such as alcohol problem assessment and treatment programs, would support less-punitive measures to reduce DUI collisions. 12 National Academies of Sciences, Engineering and Medicine (2005).

Potential priority projects are identified in consideration of the 11 collision profiles, along with input from the County team and TAC members. Additional information of the collision profiles, including a description of the profile, a map of the collisions, key statistics, and applicable countermeasures for feasibility and implementation considerations can be found in Chapter 3 of the SSAR. MTC’s Equity Priority Communities should be reviewed when prioritizing projects. This takes into consideration when improvements can be made in underserved communities. Thirty-five priority projects were identified and categorized as Tier Zero, Tier One, and Tier Two as follows: • Tier Zero corresponds to a location the County has recently enhanced or has secured funding to improve, prior to the development of this plan; the County will monitor these locations to identify if the improvements were successful in meeting the County’s safety goals for the projects. • Tier One corresponds to the top ten projects recommended by the SSAR. • Tier Two corresponds to the project locations not identified as Tier Zero or Tier One, but are identified as important locations. These projects will be revisited following the implementation of Tier One projects or with future prioritization efforts and opportunistic funding measures. The full list of 35 projects is mapped on the facing page and also listed as follows: Tier Zero Project Locations 1. Camino Diablo from Vasco Road to Byron Highway 2.

Reconfiguring the intersection to have one eastbound receiving lane that would open up to two lanes after Olinda Road, along with roadway and sidewalk improvements, would benefit all road users. Other improvements to consider include installing a roundabout at Tri Lane, installing additional signs to notify drivers when they must share the road with bicyclists, installing enhanced pedestrian crossing near bus stops, and completing a speed study. 72 Contra Costa County Vision Zero Action Plan Willow Pass Road from Port Chicago Highway to Crivello Avenue PROJECT 15 7 NUMBER OF KSI COLLISIONS ADDRESSED $2,437,500 TOTAL COST $40,300,975 TOTAL BENEFITS 16.53 B/C RATIO Project Statistics TARGET MODES Profiles Addressed 4 5 7 9 Reducing the number of vehicle travel lanes along Willow Pass Road between Port Chicago Highway and North Broadway Avenue would allow protected bike lanes to be installed. Crosswalks that are uncontrolled—meaning a crosswalk where drivers do not have to stop for a stop sign or traffic signal—should be analyzed to ensure they are consistent with the latest best practice guidance for uncontrolled crossings. Lastly, traffic signal timing should be updated to smooth traffic flow and provide pedestrians with a head start when crossing. The head start provides additional times for pedestrians to cross and enhances the visibility of pedestrians to drivers. 73Contra Costa County Vision Zero Action Plan CHAPTER 6 74 Contra Costa County Vision Zero Action Plan SAFETY EFFORTS AND PROGRAMS 75Contra Costa County Vision Zero Action Plan In recent years, efforts to improve transportation safety in the County have included a thorough analysis of collisions and applicable engineering countermeasures through the Systemic Safety Analysis Report (SSAR), as well as grants from the Office of Traffic Safety for enforcement, education, and outreach programs. Contra Costa County Systemic Safety Analysis Report Completed in early 2021, Contra Costa County’s Systemic Safety Analysis Report (SSAR) lays the groundwork and provides the resources necessary for the preparation of successful Highway Safety Improvement Program (HSIP) and other local and federally funded grant applications sought by the County. The study was funded through the SSAR program grant provided by the California Department of Transportation (Caltrans). The SSAR program helps local agencies take a strategic approach to identify systemic and hot spot safety improvement projects by completing a system-wide, multi-year, data-driven analysis of collisions. With a focus on engineering interventions, the SSAR provides a detailed look into collision and roadway database development, a review of local collision data, a safety data analysis, collision profile development, safety countermeasure selection, and project development. 76 Contra Costa County Vision Zero Action Plan Signage at the entrance of Kennedy Grove Recreation Area along San Pablo Dam Road 77Contra Costa County Vision Zero Action Plan Programs Under Way The County has several existing programs and grants focused on educating the community on multimodal safety. Chapter 6 includes additional funding sources to consider as the County expands its outreach and educational campaigns. Safe Routes to School The National Center for Safe Routes to School offers a way for communities to provide education and programs to promote safety and educate students on walking and biking to school. Contra Costa Health Services works with schools and Community Based Organizations (CBO) throughout the County to promote in-class presentations, leadership development, Walk/ Bike to School Days, assemblies, and bicycle rodeos. They also encourage on-campus kiosks promoting safe walking and bicycling. Street Smarts Diablo Region Streets Smarts Diablo is funded through 511 Contra Costa, with funding from the Contra Costa Transportation Authority and the Bay Area Air Quality Management District’s Transportation Fund for Clean Air. This program provides safe walking and bicycling assemblies for students in elementary, middle, and high school. This program currently serves the southwest part of the County. Street Smarts San Ramon Valley Street Smarts San Ramon Valley is funded by the County, the City of San Ramon, the Town of Danville, San Ramon Valley Unified School District, and San Ramon Valley Fire. This program provides safety education to students at the elementary, middle, and high school level through various contests and assemblies that includes safety education and bike rodeos. Summer Bike Challenge 511 Contra Costa hosts the annual Summer Bike Challenge, free for people of all ages and abilities. Between June and August, participants bike to as many locations identified in their community as possible, and prizes are awarded at the end of the summer. Caltrans Grant Funding The Fixing America’s Surface Transportation (FAST) Act was signed into law on December 4, 2015. Under the FAST Act, the Highway Safety Improvement Program (HSIP) is a federal- aid program focusing on infrastructure projects to achieve significant reductions in fatalities and serious injuries on public roadways. The County applies for HSIP funding annually to improve county-maintained roadways and facilities. 78 Contra Costa County Vision Zero Action Plan Mothers Against Drunk Driving (MADD) MADD is a non-profit organization seeking to stop drunk driving, support those affected by drunk driving, prevent underage drinking, and strive for stricter impaired- driving policies. Within the County, MADD hosts in-person Victim Impact Panels where participants share their stories of how drunk and drugged driving has affected their lives and the lives of their families and friends. The panel is aimed at helping offenders recognize and internalize the lasting and long-term effects of substance- impaired driving. California Highway Patrol (CHP) Programs California Highway Patrol has various DUI checkpoints set up throughout the County, although they have been less frequent recently due to the COVID 19 pandemic. CHP also uses social media and hosts presentations at schools and at the district attorney’s office warning students of the dangers of driving under the influence. CHP hosts a Start Smart program to inform newly licensed or soon-to- be licensed teenagers and their parents/guardians of the dangers of excessive speed, driving under the influence, and distracted driving. Complete Streets Corridor Studies The County’s Transportation Analysis Guidelines outline Complete Streets implementation measures for existing and future roadways. The County strives to create a connected network of facilities accommodating all modes of travel, increasing connectivity across jurisdictional boundaries, and anticipating existing and future areas of origin and destination. A few recent Complete Streets projects the County has been working on are the Appian Way Complete Streets Project, the Danville Boulevard/Orchard Complete Streets Improvement Project, and the San Pablo Avenue Complete Streets Project. Building Healthy Communities Program In partnership with local communities and organizations, Contra Costa Health Services’ Building Healthy Communities Program helps to bring the Public Health perspective to local active transportation planning efforts. They participate in walk audits, review draft plans, and conduct surveys with residents to identify needed improvements. This program also seeks funding to address neighborhood conditions that lead to injuries or poor health such as unsafe parks or lack of access to high quality active transportation amenities. 79Contra Costa County Vision Zero Action Plan CHAPTER 7 80 Contra Costa County Vision Zero Action Plan FUNDING 81Contra Costa County Vision Zero Action Plan Although many candidate projects in the SSAR are well suited for HSIP funding, there are many other potential funding sources that may be available for additional efforts. The following summarizes potential local, state, and federal funding sources related to transportation safety. The County will also continue to look for opportunities to layer safety-related projects onto other capital improvement projects, as well as maintenance projects and through review and approval of private development. Developer Fees California law allows local governments to establish and charge a fee on residential and non-residential development to fund public facilities and to service population growth. Local agencies should update their transportation analysis guidelines to reflect safety improvements for all modes of travel. Public facility fees can be charged to new development based on density and traffic impacts, and can go to a variety of public facilities, including local roadways. The County has a total of 14 traffic Area of Benefit (AOB) programs within unincorporated Contra Costa County. A traffic AOB is a development traffic mitigation fee program designed to improve the capacity and safety of the County’s road network within a defined boundary as development occurs. RAISE Grant The U.S. Department of Transportation is committed to create high-quality jobs, improve safety, protect our environment, and generate equitable economic opportunity for all American’s with their Rebuilding American Infrastructure with Sustainability and Equity (RAISE) grant. Projects will be evaluated based on merit criteria that includes safety, environmental sustainability, quality of life, economic competitiveness, state of good repair, innovation, and partnership. It is one of the few DOT discretionary programs for which regional and local governments can directly compete for multimodal transportation funding. Affordable Housing and Sustainable Communities Program (AHSC) The AHSC Program, administered by the Strategic Growth Council and implemented by the Department of Housing and Community Development (HCD), funds land use, housing, transportation, and land preservation projects to support infill and compact development that reduces GHG emissions. This program will assist project areas by providing grants and/ or loans, or any combination 82 Contra Costa County Vision Zero Action Plan thereof, that will achieve GHG emission reductions and benefit Disadvantaged Communities and Low-Income Households though increased accessibility of affordable housing, employment centers, and key destinations via low-carbon transportation. This results in fewer vehicle miles traveled through shortened or reduced trip lengths or mode shifts from Single Occupancy Vehicles to use of transit, bicycling, or walking. The project areas this funding is geared toward are transit oriented development (TOD) Project Areas, Integrated Connectivity Project (ICP) Project Areas, or Rural Innovation Project Areas (RIPA). Lifeline Transportation Program The Metropolitan Transportation Commission (MTC) has created the Lifeline Transportation Program to evaluate state and federal funds to provide grants for mobility and accessibility needs in low-income communities across the Bay Area. New guidelines are established for each cycle and the projects must address transportation gaps or barriers identified in community-based transportation plans or other local planning efforts in low- income neighborhoods. Franklin Canyon Road 83Contra Costa County Vision Zero Action Plan SB 1 Funding California’s Senate Bill 1 (SB 1), also known as the Road Repair and Accountability Act of 2017, is a landmark transportation investment to rebuild California by fixing neighborhood streets, freeways, and bridges in communities across California and targeting funding toward transit and congested trade and commute corridor improvements. The largest portion of SB 1 funding goes to California’s state-maintained transportation infrastructure. With this funding, Caltrans has a goal of repairing or replacing 17,000 miles of pavement in 10 years, spending $250 million annually for congestion solutions, over $700 million for better transit commutes, and supporting freight improvements. The other portion of SB 1 funding will go to local roads, transit agencies, and expanding the state’s pedestrian and cycle routes. SB 1 funds various grant programs. Local Partnership Program (LPP) The Local Partnership Program’s purpose is to provide local and regional transportation agencies that have passed sales tax measures, developer fees, or other imposed transportation fees, with a funding of $200 million annually from the Road Maintenance and Rehabilitation Account to fund aging infrastructure, road conditions, active transportation, and health and safety benefits projects. LPP funds are distributed through a 50% statewide competitive component and a 50% formulaic component. Both programs are eligible to jurisdictions with voter approved taxes, tolls, and fees dedicated solely to transportation and the competitive program. Local Streets and Roads Program (LSRP) California has dedicated approximately $1.5 billion per year appointed by the State Controller (Controller) to cities and counties for basic road maintenance, rehabilitation, and critical safety projects on the local streets and roads system. Cities and counties must submit a proposed projects list adopted at a regular meeting by their board or council that is then submitted to the California Transportation Commission (Commission). Once reviewed and adopted by the Commission, eligible cities and counties receive funding from the Controller and an Annual Project Expenditure Report is sent to the Commission to be transparent with program funding received and expended. 84 Contra Costa County Vision Zero Action Plan Active Transportation Program (ATP) Funding The Active Transportation Program (ATP) was created by Senate Bill 99 to encourage increased use of active modes of transportation such as walking and biking. The goals of the ATP include, but are not limited to, increasing the proportion of trips accomplished by walking and biking, increasing the safety and mobility of non- motorized users, advancing efforts of regional agencies to achieve greenhouse gas reduction goals, enhancing public health, and providing a broad spectrum of projects to benefit many types of users, including disadvantaged communities. SB 1  directs $100 million annually to the ATP, with more than 400 of the funded projects being Safe Routes to School projects and programs that encourage a healthy and active lifestyle throughout students’ lives. Caltrans Sustainable Transportation Planning Grants The Sustainable Transportation Planning Grants include two parts: Sustainable Communities Grants and Strategic Partnerships Grants. The Sustainable Communities Grants have $29.5 million set aside to encourage local and regional planning goals and best practices cited in the Regional Transportation Plan Guidelines. The Strategic Partnerships Grants set aside $4.5 million to identify and address statewide, interregional, or regional transportation deficiencies on the state highway system in partnership with Caltrans. These grants were released for Fiscal Year 2020-21 and applications were due October 17, 2019. Grant award announcements were made in June 2020. There is the possibility of another grant on the horizon, but Caltrans has not released any new information yet. Safe Routes to School (SRTS) Funding Safe Routes to School (SRTS) is a program promoting walking and bicycling to school through infrastructure improvements, tools, safety education, and incentives to encourage these modes of travel. Nationally, 10% to 14% of car trips during the morning rush hour are for school travel. SRTS can be implemented at the state, community, or local school district level. Competitive federal funding is available through the Fixing America’s Surface Transportation Act (FAST Act). Depending on the existing infrastructure, SRTS may require that education, transportation, public safety, and city planning agencies coordinate their effort. 85Contra Costa County Vision Zero Action Plan Transformative Climate Communities (TCC) Program The TCC Program funds community-led development and infrastructure projects that strive to make major advances in environmental, health, and economic benefits in California’s most disadvantages communities. Eligible improvements for this funding source include active transportation and public transit projects, transit ridership programs and passes for low-income riders, and encouraging education and planning activities to promote increased use of active modes of transportation. California Office of Traffic Safety (OTS) Grant Programs OTS administers traffic safety grants in the following areas: alcohol impaired driving, distracted driving, drug- impaired driving, emergency medical services, motorcycle safety, occupant protection, pedestrian and bicycle safety, police traffic services, public relations, advertising, and roadway safety and traffic records. 86 Contra Costa County Vision Zero Action Plan A cyclist on the Iron Horse Regional Trail 87Contra Costa County Vision Zero Action Plan CHAPTER 8 88 Contra Costa County Vision Zero Action Plan VISION ZERO CORE ELEMENTS AND ACTION PLAN 89Contra Costa County Vision Zero Action Plan The Contra Costa County Vision Zero Plan requires partnerships and collaboration across various jurisdictions, with local organizations, and with the community to be successful. Several strategies have been identified, along with the party/parties responsible for leading the action, and supporting agencies. A timeline for implementation is provided, as well as performance metrics. These actions should be periodically revisited, and actions that are successful may be expanded; actions that are not successful will be eliminated and replaced with other strategies. As conditions and strategies evolve, the strategies and supporting elements will evolve as well. The Vision Zero strategies are categorized into three Core Elements: Leadership and Commitment Safe Roadways and Safe Speeds Data-Driven Approach, Transparency, and Accountability 90 Contra Costa County Vision Zero Action Plan A pedestrian crossing the street in Contra Costa Centre 91Contra Costa County Vision Zero Action Plan 1 The TAC will share updates on crash data, resources, current projects, policy evolution, funding opportunities, equity data, emerging issues, and other information. The County’s Public Works Department and Health Services Department will coordinate invites to stakeholders to participate in the TAC, which includes, but is not limited to, Social Services, Economic Development, County Connection (also known as Contra Costa County Transit Authority ), Board of Supervisors (BOS), California Highway Patrol (CHP), and other non-profits and community-based organizations (CBOs). Routine collaboration between stakeholders and partners will ensure that County-led engineering countermeasures are supported by coordinated efforts led by local and regional partners. Strategies for mutual accountability include conducting briefings and presentations at board and agency meetings, collecting and sharing information on a regular basis, and updating a public-facing database (or scorecard) on the progress toward Vision Zero.

Nothing in this Board Order shall prevent the Board from re-awarding the contract to another bidder in cases where the successful bidder establishes a mistake, refuses to sign the contract, or fails to furnish required bonds or insurance (see Public Contract Code Sections 5100-5107). FISCAL IMPACT: The construction contract and associated fees of this project will be funded by 22% Highway Safety Improvement (HSIP) Grant Funds, 58% Discovery Bay West Mitigation Funds, 6% Discovery Bay Area of Benefit (AOB) Funds, and 14% East County AOB Funds. BACKGROUND: The above project was previously approved by the Board of Supervisors, plans and specifications were filed with the Board, and bids were invited by the Public Works Director. On January 25, 2022, the Public Works Department received bids from the following contractors: BIDDER, TOTAL AMOUNT, BOND AMOUNTS GradeTech Inc., $958,947.50 Granite Rock Company, $997,714.00; Payment: $997,714.00; Performance: $997,714.00 McGuire and Hester., $1,009,557.00 Dirt Dynasty, Inc., $1,195,310.50 Kerex Engineering, Inc., $1,226,502.00 Gruendl Inc. dba Ray’s Electric, $1,538,043.90 This is a federally funded project subject to the County’s Disadvantaged Business Enterprise (DBE) Program’s goals and requirements. The Public Works Director has determined and reports that the lowest monetary bidder, GradeTech, achieved 11.4% DBE participation, which failed to meet the 17% DBE goal for this project, and failed to submit an adequate good faith effort to comply with the requirements for this project. The Public Works Director recommends rejection of the bid submitted by GradeTech. The second bidder listed above, Granite Rock, submitted the lowest responsive and responsible bid, which is $11,843.00 less than the next lowest bid. On February 7, 2022 GradeTech was notified in writing of the Public Work Director’s determination that their bid was non-responsive for failure to comply with the DBE requirements of the project specifications (see Attachment A). GradeTech did not appeal the determination, as provided in the project specifications. The Public Works Director has determined that Granite Rock achieved DBE participation of 21.5%, which exceeded the DBE goal for this project, and recommends that the construction contract be awarded to by Granite Rock. The Public Works Director recommends that the bid submitted by Granite Rock is the lowest responsive and responsible bid, which is $11,843.00 less than the next lowest bid, and this Board concurs and so finds. The Board of Supervisors previously determined that the project is exempt from the California Environmental Quality Act (CEQA) as a Class 15301(c) Categorical Exemption, and a Notice of Exemption was filed with the County Clerk on December 6, 2018. The general prevailing rates of wages, which shall be the minimum rates paid on this project, have been filed with the Clerk of the Board, and copies will be made available to any party upon request. CONSEQUENCE OF NEGATIVE ACTION: Construction of this project would be delayed, and the project might not be built. ATTACHMENTS Attachment A RECOMMENDATION(S): ACCEPT the 2021 Semi-Annual Report of Real Estate Acquisition Acceptances dated July 1, 2021 through December 31, 2021, approved by the Public Works Director for the acquisitions of any interest in real property where the purchase price for the real property interest did not exceed $100,000, in the Brentwood, Briones, Byron, Clayton and Knightsen areas. FISCAL IMPACT: No fiscal impact. BACKGROUND: Pursuant to the Contra Costa County, Ordinance Code, Title 11, Division 1108, Chapter 1108-8.002, “The Board of Supervisors authorizes the Public Works Director, or designee, to perform all acts necessary to approve and accept for the County, the acquisition of any interest in real property where the purchase price for the real property interest does not exceed one hundred thousand dollars ($100,000).” The Public Works Director shall submit a semi-annual report to the Board of Supervisors on each acquisition done pursuant to this section, including the interest acquired, its price, and the necessity for the purchase, which is described in the attached Semi-Annual Acceptance Report.

Glover, District V Supervisor Contact: Eric Angstadt; 925-655-2042 I hereby certify that this is a true and correct copy of an action taken and entered on the minutes of the Board of Supervisors on the date shown. ATTESTED: March 1, 2022 Monica Nino, County Administrator and Clerk of the Board of Supervisors By: Stacey M. Boyd, Deputy cc: C. 13 To:Board of Supervisors From:Monica Nino, County Administrator Date:March 1, 2022 Contra Costa County Subject:Negotiate and Sign a Joint Use Agreement with CCTA for use of the Former Concord Naval Weapons Station & County Airports BACKGROUND: (CONT'D) addition, CCTA and its research partners have also indicated a desire to test other kinds of autonomous vehicles, including drones. CCTA would like to negotiate a use agreement with the County Airports to define the costs and terms of use to allow for expanded testing areas beyond the GoMentum Station area. The airports have an agreement in place already with another entity for testing at the airports and the CCTA agreement would be in addition to that agreement; the terms would need to be negotiated to not infringe on the existing agreement. The joint use agreement is designed to be a master agreement between Contra Costa County (CCC) and CCTA to allow CCTA to use land controlled by CCC for the benefit of research and testing of various vehicles by its partners in the GoMentum Station project. The master agreement will set out the basic responsibilities of each party and will included separate attachments with the specific approval, consulting and use requirements and fee schedule if appropriate for each property covered by the agreement. Both parties agree that the use of the airport facilities is ultimately governed by the Federal Aviation Administration (FAA) rules and that the parties will negotiate specific procedures, to be codified in separate attachments, that inform how CCTA will propose, and the County will evaluate any future use. The intent is to establish the master agreement and an attachment specific to the current GoMentum Station area first, with a goal of completing the agreement by June, 2022. Representatives from the Office of the Sheriff and ConFire will work with the County Administrator and County Counsel to negotiate the agreement and attachment. This will allow time for the County to appoint a new airport director to negotiate the attachments to the master agreement specific to each airport with a goal of completing those by the end of 2022. The attached term sheet shows the basic intent and responsibilities of each party. The County stands to benefit from this arrangement in several ways. GoMentum Station brings multiple technology companies to Contra Costa County for testing of its vehicles. CCTA has indicated that its partners wish to invest in building additional testing facilities at GoMentum Station which has the potential, if properly coordinated, of saving the County significant money by performing work that the County would otherwise have to perform once the land is transferred by the Navy to the County. Including the airports in the partnership would give CCTA the ability to market Contra Costa County as a premier testing area for multiple types of autonomous vehicles and bring additional testing partners to the County. Increased marketing could lead to an increase in airport revenues as additional users would pay the agreed upon costs for using airport facilities. ATTACHMENTS CCTA CCC Term Sheet 1 Draft Master Use Agreement Between Contra Costa County and Contra Costa County Transportation Authority Framework: The joint use agreement is designed to be a Master Agreement between Contra Costa County (CCC) and Contra Costa Transportation Authority (CCTA) to allow CCTA to use land controlled by CCC for the benefit of research and testing of various vehicles by their partners in Go Mentum Station project. The Master Agreement will set out the basic responsibilities of each party and will included separate attachments with the specific approval, consulting and use requirements and fee schedule if appropriate for each property covered by the agreement. Both parties agree that the use of the airport facilities is ultimately governed by the Federal Aviation Administration (FAA) rules and that the parties will negotiate specific procedures, to be codified in separate attachments, that inform how CCTA will propose, and CCC will evaluate any future use.

In fact, as many as one in four patients receiving long-term opioid therapy in a primary care setting struggles with opioid use disorder (OUD); and WHEREAS, prescription opioid overdose deaths also often involve benzodiazepines. Benzodiazepines are central nervous system depressants used to sedate, induce sleep, prevent seizures, and relieve anxiety. The Centers for Disease Control and Prevention (CDC) recommends avoiding taking benzodiazepines while taking prescription opioids whenever possible; and WHEREAS, in 2020, in Contra Costa County, there were 478,723 opioid prescriptions given to patients which is an age-adjusted rate of 347.4 per 1,000 residents, higher than the state rate of 333.3; and WHEREAS, in 2020, a total of 16,537 emergency department visits occurred in California that were related to any opioid overdose and 93 of those visits occurred in Contra Costa County; and WHEREAS, provisional data from the Center for Disease Control (CDC) indicate that of the estimated 100,306 drug overdose deaths nationally during 12-month period ending in April 2021, 75,673 were from opioids and 161 of those opioid related overdose deaths occurred in Contra Costa County; and WHEREAS, overdose deaths from synthetic opioids (primarily illicitly manufactured fentanyl), psychostimulants such as methamphetamine and cocaine deaths also increased in the 12-month period ending in April 2021 as did deaths from natural and semi-synthetic opioids (such as prescription pain medication); and WHEREAS, it is estimated that the “economic burden” of prescription opioid misuse alone in the United States is $78.5 billion a year, including the costs of healthcare, lost productivity, addiction treatment, and criminal justice involvement; and WHEREAS, the Contra Costa County Board of Supervisors supports April 30, 2022 as “National Prescription Drug Take Back Day” as declared by the DEA and encourages residents to locate their local collection site via www.dea.gov and safely dispose of their accumulated expired and unwanted prescription drugs that day and throughout the year; and WHEREAS, the Contra Costa County Medication Education and Disposal Safety (MEDS) Coalition engages youth and adult stakeholders from across the county to participate in Prescription Drug Abuse Awareness Month activities to raise about prescription drug safety awareness, promote safe medication storage and disposal and ensure naloxone is available for those at high risk of opioid related overdose. THEREFORE, BE IT RESOLVED THAT the Contra Costa County Board of Supervisors does hereby declare March 2022 as Prescription Drug Abuse Awareness Month and encourages all citizens to participate in prescription drug abuse related prevention programs and activities. Be it also resolved that the County Board of Supervisors encourages all community members to pledge, “Spread the Word… One Pill Can Kill”. ___________________ KAREN MITCHOFF Chair, District IV Supervisor ______________________________________ JOHN GIOIA CANDACE ANDERSEN District I Supervisor District II Supervisor ______________________________________ DIANE BURGIS FEDERAL D.

Glover, District V Supervisor Contact: Jaime Jennet 925-608-6716 I hereby certify that this is a true and correct copy of an action taken and entered on the minutes of the Board of Supervisors on the date shown. ATTESTED: March 1, 2022 Monica Nino, County Administrator and Clerk of the Board of Supervisors By: Stacey M. Boyd, Deputy cc: C. 19 To:Board of Supervisors From:Anna Roth, Health Services Director Date:March 1, 2022 Contra Costa County Subject:Community Member Seat for Council on Homelessness BACKGROUND: (CONT'D) SUMMARY OF RECRUITMENT EFFORTS/NOMINEES FOR MEMERSHIP The Council on Homelessness continues to make every effort to fill its vacant seats. These efforts include sending a targeted email solicitation via the Continuum of Care mailing list (2000+ contacts that include each Supervisor’s office), announcing vacancies at public Council on Homelessness meetings and posting information about the vacancies and application materials on the Council on Homelessness website. A nominating committee consisting of four (4) seated nonconflicted Council on Homelessness members reviewed applications and supplemental information including a supplemental application for all seats. The committee used a rubric to evaluate the applicants that included capacity to meet the functions and tasks of the Council on Homelessness as stated in the Council’s bylaws and evaluating the diversity of current and potential Council members to ensure that a diverse population contributes to deliberations and decision-making—including consumers and community members—as well as gender, ethnic, cultural, and geographical representation. Following a close review of the twenty (20) applications for this seat by a nominating committee, the Council on Homelessness recommends appointing: Community Member Representative1. Keva Dean Community Member Antioch Based on the above information and due to the absence of a December or January Family and Human Services Committee meetings, the department has received approval from the FHS Chair to recommend this appointment directly to the Board of Supervisors. CONSEQUENCE OF NEGATIVE ACTION: Failure to appoint a member will reduce public participation on the Council on Homelessness and impact meeting quorum. RECOMMENDATION(S): ACCEPT resignation of Evelyn Howard, DECLARE a vacancy in the At-Large 5 - Alternate Seat on the Alcohol and Other Drugs Advisory Board, and DIRECT the Clerk of the Board to post the vacancy with a term ending June 30, 2023. FISCAL IMPACT: There is no fiscal impact for this action. BACKGROUND: The Alcohol and Other Drugs Advisory Board’s mission is to identify needs in the community with regards to substance use prevention or treatment. The findings and recommendations are provided to the Board of Supervisors, the Health Services Department, Behavioral Health Division, and the Alcohol and Other Drugs Services (AODS) Administration. The Board is comprised of five Supervisorial District seats, six At-Large Member Seats, and three At-Large Alternate Seats. Ms. Evelyn Howard is a high school student who was serving as an At-Large 5 - Alternate Seat. Ms. Howard vacated the seat last Fall due to conflicts with competing school priorities. CONSEQUENCE OF NEGATIVE ACTION: The seat will remain unfilled, and this will potentially make it more difficult to achieve a quorum and will potentially lessen the viewpoint of communities impacted by substance use issues in AOD Board deliberations.

I would like to be appointed to and serve in the Mental Health Commission in order to bring more awareness to the first-hand experiences with mental health in the Hispanic/Latinx population. As a first- generation Mexican American woman living in San Pablo, California, it is imperative to bring a cultural and holistic lens to the mental health commission in order to better serve Contra Costa County residents. Personally, I have dealt with and continue to navigate mental health challenges such as anxiety, intrusive thoughts, depression, and body issues. While it was difficult to deal with, I began facilitating mental health discussions with my immigrant parents and siblings in order to de-stigmatize it and provide healing. Additionally, I began working as a mental health advocate at Berkeley City College’s Undocumented Community Resource Center where I used my story and experiences to positively impact students and help them with mental health challenges. I realized through my experiences that many of the same mental health challenges I have dealt with as a Latina are all too common in the Hispanic/Latinx community. These challenges are also a sign of the macro level root issues and needs that need to be addressed in our communities in order to improve the mental, physical, emotional, and social well being of residents. As I have advocated and continue to advocate for mental health awareness, I am ready to bring my skills and experiences as a Latina to serve on the Mental Health commission and better help residents in my community.

I hold a Mental Health First Aid USA Certificate and am certified by the National Council for Behavioral Health. I am experienced in providing help to individuals experiencing mental health problems such as depression, anxiety disorders, psychosis, and substance use disorders. I served as Define American’s West Regional Chapter Representative where I learned to advocate for social justice and learned how to best have cultural competence and humility when advocating for Mental Health in the undocumented community. Would you like to be considered for appointment to other advisory bodies for which you may be qualified? Yes No Do you have any obligations that might affect your attendance at scheduled meetings? Yes No If Yes, please explain: I am currently an undergraduate student majoring in Sociology at UC Berkeley.

AGENDA ATTACHMENTS Appropriations Adjustment No. 5032 MINUTES ATTACHMENTS Signed: Appropriations & Adjustment No. 5032 RECOMMENDATION(S): AUTHORIZE the Auditor-Controller to transfer $100,000 from Park Dedication/Park Impact Fund Accounts designated for the Kensington area to the Contra Costa County Public Works Department to help finance preliminary studies for the Kensington Pathway improvements in the unincorporated community of Kensington. FISCAL IMPACT: No impact to the General Fund. 100% Park Dedication and Park Impact Fees deposited in the Kensington area park accounts will be used to finance the preliminary studies. BACKGROUND: Project Description The project will provide foundational funding for a thriving pathway network in the Kensington community, thus expanding the use and life of the pathways. The initial work to ensure Kensington has a safe pathway network includes the following preliminary studies and tasks: * Preliminary survey and land rights assessment, * Construction cost estimates, * Financing options to expand the use and life of the pathways, * Legal consultation, and * Interdepartmental coordination and community outreach. Kensington Path Background The original Kensington development included a series of pathways that have become an integral part of Kensington community. The pathways consist of approximately 15 individual pathway segments and together provide over three quarters of a mile of pathways in the Kensington community as shown on the attached map. The condition of the paths varies from inaccessible to well maintained. While the Kensington paths have been an enduring component of the community’s character, the ownership and responsibility of the paths are uncertain. There is no clear owner of the pathways nor is there a responsible entity to provide ongoing maintenance and improvement. The paths are currently maintained by volunteers. This has resulted in varying degrees of maintenance and improvements over the years.

Boyd, Deputy cc: C. 24 To:Board of Supervisors From:John Kopchik, Director, Conservation & Development Department Date:March 1, 2022 Contra Costa County Subject:Park Dedication and Park Impact Fee Fund Authorization for Kensington Paths BACKGROUND: (CONT'D) Given the importance of the pathways to the community of Kensington, the County has committed to conducting the foundational work required to create a plan for a thriving pathway system. Supervisor Gioia has supported the community’s request to take the first step to preserving and improving the Kensington paths. Park Fund Background The County imposes fees on residential development to fund park and recreational facilities under both the County's Park Dedication Ordinance and the County's Park Impact Fee Ordinance. Funds from these fees are deposited into accounts associated with the community where the residential development occurs to ensure the funds are directed to park and recreational facilities which serve the residents affected by the development.

Balbas, Public Works Director/Chief Engineer Date:March 1, 2022 Contra Costa County Subject:Approve Agreement with Urban Tilth for the North Richmond Watershed Connections Project. Project No. 7517-6W7257 BACKGROUND: (CONT'D) is working in collaboration with UT and The Watershed Project (TWP) to plan, design, and construct the Project. The Project is a multi-benefit project in North Richmond with three components. Component 1 includes the planting of trees in addition to the installation of sidewalks and bike lanes along Fred Jackson Way between Grove Avenue and Brookside Drive as part of the County Public Works’ First Mile/Last Mile project. Component 2 is the construction of sidewalks, a bike lane, and stormwater infrastructure, including a linear raingarden with some street trees. Component 2 is being completed by UT, which is responsible for designing and constructing the sidewalks, bike lane, and stormwater infrastructure (linear raingardens and bioswales) and the planting of street trees within County road right-of-way. Per the grant requirements, installation of the Project is scheduled to be completed by December 31, 2022. Component 3 of the Project is an urban greening component consisting of an “Adopt a Tree” program and the installation of wayfinding elements in the neighborhood between the North Richmond Baseball Field and Chesley Avenue and between Fred Jackson Way and 7th Street. Component 3 is being completed by TWP under a separate agreement. Pursuant to the California Environmental Quality Act (CEQA), a Mitigated Negative Declaration (MND) was prepared for Component 2 of the Project, concluding that the Project will not have a significant effect on the environment. The MND was approved by the County Zoning Administrator on November 13, 2018, and a Notice of Determination was subsequently posted as required by law. The required mitigation measures are being implemented as part of the construction work for Component 2. The proposed Agreement includes insurance and indemnification to protect the County against potential liabilities occurring during construction of the Project, which will be performed by a contractor hired by UT. Under the proposed Agreement, the County is passing through to UT $422,000 in grant funding provided by SCC for the installation by UT of sidewalk, bike lane, and stormwater infrastructure (linear raingardens and bioswales) and the planting of street trees, and the County is using $78,000 in SCC grant funding for County administration and management of the Project. The Agreement is needed to authorize UT to construct and implement Component 2 of the Project and to invoice the County for the work completed under the SCC grant. Per the terms of the SCC grant, the Agreement is subject to SCC’s approval and will be finalized when that approval is received. CONSEQUENCE OF NEGATIVE ACTION: If the Agreement is not approved, the County will not be able to complete the Project work and the state funding provided by SCC may be lost.

Exhibit X (Maintenance and Operations) to the Base Agreement provides that the CalSAWS Consortium members may purchase services under the Base Agreement in connection with the CalSAWS system, including services provided by Accenture’s subcontractors, such as Hyland LLC. EHSD is requesting to purchase eleven (11) kiosks for use in the lobbies of four (4) existing County sites and the asset-tagging, configuration, and deployment of five (5) Facilitated Access Control Tablets (FACTs). The purchase also includes hardware charges, software charges, and hardware support charges for the new equipment, as well as administrative charges for equipment asset-tagging, imaging, configuration, transportation, and ongoing recurring technical infrastructure services charges for enhanced central support for the managed kiosks and FACTs, all of which are described in the County order form. The kiosks will be used by EHSD clients to electronically submit documents and check-in for appointments. The FACTs allow workers to login using their CalSAWS credentials to assist customers in the lobby to check them in for appointments and scanning appointment letters. The FACTs can also be used for assigning kiosk flows. These enhancements save reception staff time by allowing them to focus on serving customers requiring in-person assistance. Lobby Management and the corresponding equipment will be used by the customers and staff of EHSD beginning with cutover to CalSAWS in October 2022. CONSEQUENCE OF NEGATIVE ACTION: If this contract is not approved, the current lobby management system will not work when EHSD transitions to CalSAWS in October 2022, and EHSD will be unable to provide self-service imaged document submission and appointment check-in. This will increase customer wait times and result in unnecessary customer interactions and clerical workload, creating a corresponding reduction in capacity to provide lobby reception services to the public.

After installation completion, the risk of loss or damage for the LRS Hardware and CalSAWS Hardware shall be borne by CONSORTIUM, except loss or damage attributable to the CONTRACTOR’S fault or negligence. 13. PROHIBITION AGAINST DELEGATION AND ASSIGNMENT: 13.1 GENERAL: CONTRACTOR shall not assign (whether by contract, by operation of law, or otherwise) its rights or delegate its duties under this Agreement, or both, whether in whole or in part, without the prior consent of CONSORTIUM. Any attempted assignment or delegation that does not have such prior CONSORTIUM consent shall be null and void. For purposes of this Paragraph 13, CONSORTIUM consent shall require a written Amendment to this Agreement that is formally approved and executed by the Parties. Any billings to CONSORTIUM by any unapproved delegatee or assignee on any claim under this Agreement shall not be paid by CONSORTIUM nor constitute any obligation of CONSORTIUM. Any payments by CONSORTIUM to any approved delegatee or assignee on any claim under this Agreement shall be deducted, at CONSORTIUM’s sole discretion, against any claims which CONTRACTOR may have against CONSORTIUM, whether under this Agreement or otherwise. Any assumption, assignment, delegation, or takeover of any of CONTRACTOR’s duties, responsibilities, obligations, or performance of same by any entity other than CONTRACTOR, whether through assignment, subcontract, delegation, merger, buyout, or any other mechanism, with or without consideration for any reason whatsoever without CONSORTIUM’s express prior approval, shall be a material breach of this Agreement which may result in the termination of this Agreement.

CalSAWS Amended, Restated and Revised LRS Agreement 1832361.1 14448-005 Page 118 13.2 CHANGES OF CONTROL: Partners or other equity holders of CONTRACTOR may sell, exchange, assign, divest, or otherwise transfer any interest they may have therein. However, within five (5) Working Days after a public announcement of any change in control of CONTRACTOR that will or does give majority control of CONTRACTOR to any person(s), corporation, partnership, or other legal entity other than the majority controlling interest therein at the time of execution of this Agreement, CONTRACTOR shall give CONSORTIUM notice thereof. If there is no public announcement of such change of control, CONTRACTOR shall notify CONSORTIUM of the change within five (5) Working Days following the effective date of the change of control. If CONSORTIUM, in good faith, reasonably determines that the change of majority control of CONTRACTOR would prevent CONTRACTOR from being qualified and eligible to receive a contract award under applicable federal, State, and/or local laws, rules, regulations, ordinances, guidelines, directives, policies, or procedures (e.g., the majority control of CONTRACTOR is held by a debarred entity), then CONSORTIUM may terminate this Agreement, and while neither a termination for convenience nor a termination for default, CONSORTIUM shall have the same rights and may pursue the same remedies against CONTRACTOR as it would have and could pursue in the event of default by CONTRACTOR. 14. WARRANTY AGAINST CONTINGENT FEES: 14.1 CONTRACTOR warrants that no person or selling agency has been employed or retained to solicit or secure this Agreement upon any agreement or understanding for a commission, percentage, brokerage, or contingent fee, excepting bona fide employees or bona fide established commercial or selling agencies maintained by CONTRACTOR for the purpose of securing business. 14.2 For breach of this warranty, CONSORTIUM shall have the right to terminate this Agreement and, in its sole discretion, deduct from this Agreement price or consideration, or otherwise recover, the full amount of such commission, percentage, brokerage, or contingent fee.

INDEPENDENT CONTRACTOR STATUS: 15.1 This Agreement is by and between CONSORTIUM and CONTRACTOR and is not intended, and shall not be construed, to create the relationship of agent, servant, employee, partnership, joint venture, or association, as between CONSORTIUM and CONTRACTOR. The employees and agents of one party shall not be, or be construed to be, the employees or agents of the other party for any purpose whatsoever. 15.2 CONTRACTOR shall be solely liable and responsible for providing to, or on behalf of, all persons performing Work pursuant to this Agreement, all compensation and benefits. CONSORTIUM shall have no liability or responsibility for the payment of any salaries, wages, unemployment benefits, disability benefits, federal, State, or local taxes, or other compensation, benefits, or taxes for any personnel provided by or on behalf of CONTRACTOR. 15.3 CONTRACTOR understands and agrees that all persons performing Work pursuant to this Agreement are, for purposes of workers’ compensation benefits, solely employees of CONTRACTOR and not employees of CONSORTIUM. CONTRACTOR shall be solely liable and responsible for furnishing any and all workers’ compensation benefits to any person as a result of any injuries arising from or connected with any Work performed by or on behalf of CONTRACTOR pursuant to this Agreement. 15.4 CONTRACTOR shall provide to CONSORTIUM an executed CONTRACTOR Employee Acknowledgment, Confidentiality, and Copyright Assignment Agreement (Exhibit J) for each of its employees performing Work under this Agreement.

SUBCONTRACTING: 16.1 CONSORTIUM has relied, in entering into this Agreement, on the reputation of and on obtaining the personal performance of CONTRACTOR itself. Consequently, no performance of this Agreement, or any portion thereof, shall be subcontracted by CONTRACTOR without the prior consent of CONSORTIUM as provided in this Paragraph 16. Any attempt by CONTRACTOR to subcontract any performance, obligation, or responsibility under this Agreement, without the prior consent of CONSORTIUM, shall be null and void and shall constitute a material breach of this Agreement, upon which CONSORTIUM may immediately terminate this Agreement. CONSORTIUM hereby consents to the use of Northrop Grumman, Xerox and DXC as Subcontractors. 16.2 If CONTRACTOR desires to subcontract any portion of its performance, obligations, or responsibilities under this Agreement, CONTRACTOR shall make a written request to CONSORTIUM for approval to enter into the particular subcontract.

CONSORTIUM’s approval or written disapproval for CONTRACTOR to enter into a particular subcontract shall be given or withheld within thirty (30) days after receipt of all the information and documentation set forth above in Subparagraph 16.2. CONSORTIUM’s failure to either approve or disapprove the proposed subcontract within thirty (30) days shall be deemed a disapproval by CONSORTIUM. In the event that CONSORTIUM approves any subcontract, such approval shall apply only to the particular subcontract approved and shall not be deemed approval of any additional subcontract. 16.4 CONTRACTOR shall indemnify, defend, and hold harmless CONSORTIUM and the State, and their respective officers, employees, and agents, from and against any and all third party and Subcontractor claims, demands, liabilities, damages, costs, and expenses, including defense costs and legal, accounting or other expert, and consulting or professional fees, in any way arising from, connected with, or related to CONTRACTOR’s use of any Subcontractor, including any officers, employees, or agents of any Subcontractor, in the same manner as required for CONTRACTOR, its officers, employees, and agents, under this Agreement.

Further, CONSORTIUM approval of any subcontract shall not be construed to limit in any way CONTRACTOR’s performance, obligations, or responsibilities to CONSORTIUM, nor shall such approval limit in any way any of CONSORTIUM’s rights or remedies contained in this Agreement. Additionally, CONSORTIUM approval of any subcontract shall not be construed in any way to constitute the determination of the allowableness or appropriateness of any cost or payment under this Agreement. 16.6 Further, in the event that CONSORTIUM consents to any subcontracting, such consent shall be subject to CONSORTIUM’s right to direct the CONTRACTOR to terminate, in whole or in part, any subcontract at any time upon notice to CONTRACTOR consistent with the terms of such subcontract when such Subcontractor is in material breach of its subcontract. CONSORTIUM shall not be liable or responsible in any way to CONTRACTOR, to any Subcontractor, or to any officers, employees, or agents of CONTRACTOR or any Subcontractor, for any claims, demands, damages, liabilities, losses, costs, or expenses, including defense costs and legal, accounting and other expert, consulting or professional fees, in any way arising from, connected with, or related to CONSORTIUM’s exercise of such rights. 16.7 In the event that CONSORTIUM consents to any subcontracting, CONSORTIUM’s ongoing approval rights with regard to CONTRACTOR’s staff as set forth in Subparagraphs 3.3 (Approval of CONTRACTOR’s Staff) and 3.6 (Background and Security Investigation) shall be extended to all Subcontractor staff performing Work. CONSORTIUM shall not be liable or responsible in any way to CONTRACTOR or to any Subcontractor, for any liability, damages, costs, CalSAWS Amended, Restated and Revised LRS Agreement 1832361.1 14448-005 Page 123 or expenses arising from, connected with, or related to CONSORTIUM’s exercise of such rights. 16.8 In the event that CONSORTIUM consents to any subcontracting, the Subcontractor, on behalf of itself, its successors and administrators, shall assume and be bound by and shall be deemed to have assumed and agreed to be bound by each and all of the provisions of this Agreement and any Amendment thereto applicable to such Subcontractor given its responsibilities in performing the Work. CONTRACTOR shall be liable for any breach of this Agreement by a Subcontractor. 16.9 In the event that CONSORTIUM consents to any subcontracting, such consent shall apply to each particular subcontract only and shall not be, or be construed to be, a waiver of this Paragraph 16 or a blanket consent to any further subcontracting. 16.10 CONSORTIUM Executive Director is hereby authorized to act for and on behalf of CONSORTIUM pursuant to this Paragraph 16, including consenting to any subcontracting or lower tier subcontracting. 16.11 CONTRACTOR shall be solely liable and responsible for any and all payments and other compensation to all Subcontractors and their officers, employees, and agents.

TERMINATION FOR DEFAULT: 35.1 CONSORTIUM may, by notice to CONTRACTOR, terminate the whole or any part of this Agreement in any one of the following circumstances: (A) If CONTRACTOR fails to perform or provide in any material respect any Task, Subtask, Deliverable, good, or service within: (i) the times specified in this Agreement, including the applicable notice and/or cure periods, if CalSAWS Amended, Restated and Revised LRS Agreement 1832361.1 14448-005 Page 21 any (if no cure period is specified in this Agreement, CONTRACTOR shall have ten (10) days to provide a plan to cure, and thirty (30) days to cure following CONSORTIUM Executive Director’s approval of the plan, prior to termination under this Subparagraph 35.1); or (ii) any extensions thereof as CONSORTIUM Executive Director may authorize in writing; provided that (1) nothing in this Subparagraph 35.1(A) shall in any way limit or modify any rights of CONSORTIUM or obligations of CONTRACTOR relating to timely performance by CONTRACTOR as otherwise set forth in this Agreement and (2) the above cure periods shall in no way apply to the determination or calculation of the Liquidated Damages; or (B) Except as set forth in Subpart (A) of this Subparagraph 35.1, i f CONTRACTOR fails to perform or comply in any material respect with any of the provisions of this Agreement, or so fails to make progress as to endanger performance of this Agreement in accordance with its terms, and, in either of these two circumstances, does not cure such failure within a period of thirty (30) days (or such longer period as CONSORTIUM Executive Director may authorize in writing) after receipt of notice from CONSORTIUM specifying such failure; provided that: (i) CONTRACTOR shall not be entitled to any cure period, and CONSORTIUM may terminate this Agreement immediately, in the event that CONTRACTOR’s failure to perform or comply is not reasonably capable of being cured by CONTRACTOR in a reasonable time; and (ii) the above cure periods shall in no way apply to the determination or calculation of the Liquidated Damages. If, pursuant to the preceding sentence, CONSORTIUM has terminated this Agreement without providing a cure period, and subsequently a final determination is made that the default was capable of being cured, then the rights and obligations of the Parties shall be the same as if the notice of termination had been issued pursuant to Paragraph 37 (Termination for Convenience). (C) Accenture plc is in material default of Exhibit D (Accenture plc Performance Guarantee) and does not cure such default within a period of CalSAWS Amended, Restated and Revised LRS Agreement 1832361.1 14448-005 Page 22 thirty (30) days (or such longer period as CONSORTIUM Executive Director may authorize in writing) after receipt of notice to CONTRACTOR and Accenture plc from CONSORTIUM specifying such default. 35.2 In the event that this Agreement is terminated in whole or in part other than as provided in Subparagraphs 8.4 (Termination for Non-Appropriation of Funds) and 35.7 and Paragraph 37 (Termination for Convenience), then: (A) CONSORTIUM shall have the right to procure, upon such terms and in such a manner as is consistent with CONSORTIUM’s procurement policies, any Deliverables, Tasks, Subtasks, goods, and services equivalent to those so terminated, and CONTRACTOR shall be liable to CONSORTIUM for, and shall promptly pay to CONSORTIUM, any and all excess costs incurred by CONSORTIUM to procure and furnish such equivalent Deliverables, Tasks, Subtasks, goods, and services; and (B) CONTRACTOR and CONSORTIUM shall continue the performance of this Agreement to the extent not terminated under the provisions of this Agreement; and (C) CONTRACTOR understands and agrees that CONSORTIUM has obligations that it cannot satisfy without use of the LEADER Replacement System, the CalSAWS System or an equivalent system, and that a failure to satisfy such obligations could result in irreparable damage to CONSORTIUM and the persons and entities it serves. Therefore, CONTRACTOR agrees that in the event of any termination of this Agreement, in whole or in part, as a result of the breach hereof by CONTRACTOR, in whole or in part, CONTRACTOR shall fully cooperate with CONSORTIUM, at no additional cost to CONSORTIUM, in the transition of CONSORTIUM and the LEADER Replacement System and CalSAWS System to a new system and for such period of time as is reasonably required for such transition, toward the end that there be no interruption of CONSORTIUM’s day-to-day operations due to the CalSAWS Amended, Restated and Revised LRS Agreement 1832361.1 14448-005 Page 23 unavailability of the LEADER Replacement System or CalSAWS System during such transaction. 35.3 Except with respect to defaults of any Subcontractors, CONTRACTOR shall not be liable for any failure or delay in performance, if its failure or delay to perform this Agreement arises out of force majeure. As used in this Subparagraph 35.3, “force majeure” means causes beyond the reasonable control of CONTRACTOR , including fires, floods, epidemics, quarantine restrictions, other Acts of God, strikes, freight embargoes, or acts of terrorism, but in every such case the failure or delay to perform must be beyond the reasonable control, and not due to the fault or negligence of, CONTRACTOR. If the failure or delay to perform is caused by the default of a Subcontractor, and if such default arises out of causes beyond the reasonable control of both CONTRACTOR and Subcontractor, and is not due to the fault or negligence of either of them, CONTRACTOR shall not be liable for any such failure or delay to perform, unless the goods or services to be furnished by the Subcontractor are obtainable from other sources at commercially reasonable rates: (i) in sufficient time to permit CONTRACTOR to meet the required performance schedule; or (ii) in a materially shorter time in a commercially reasonably manner. CONTRACTOR agrees to use all reasonable commercial efforts to obtain such goods or services from other sources. As used in this Subparagraph 35.3, the terms “Subcontractor” and “Subcontractors” mean Subcontractors at any tier. CONTRACTOR is acting as an agent of the CONSORTIUM to configure a cloud instance procured by CONSORTIUM from Amazon Web Service and is not responsible for failures of Amazon Web Services or its products or services. 35.4 If, after CONSORTIUM has given notice of termination under the provisions of this Paragraph 35, it is determined by CONSORTIUM that CONTRACTOR was not in default under the provisions of this Paragraph 35, or that the default was excusable under the provisions of this Paragraph 35, the rights and obligations of the Parties shall be the same as if the notice of termination had been issued pursuant to Paragraph 37 (Termination for Convenience). CalSAWS Amended, Restated and Revised LRS Agreement 1832361.1 14448-005 Page 24 35.5 Each party shall have a duty to mitigate damages that would otherwise be recoverable from the other party pursuant to this Agreement by taking appropriate and commercially reasonable actions to reduce or limit the amount of such damages. 35.6 The rights and remedies of CONSORTIUM provided in this Paragraph 35 shall not be exclusive and are in addition to any other rights and remedies provided by law, at equity, or under this Agreement. 35.7 If CONSORTIUM fails to pay any invoice approved by CONSORTIUM in accordance with Subparagraph 9.4 (CONSORTIUM Approval of Invoices) within sixty (60) days of the date of receipt of such approved invoice, then CONTRACTOR may provide notice to CONSORTIUM of its intent to suspend this Agreement unless CONSORTIUM makes payment for such approved invoice. Upon receipt of such notice, CONSORTIUM shall have thirty (30) days (or such longer time as CONTRACTOR may authorize in writing) to cure any such failure to pay the approved invoice. If CONSORTIUM cures such failure to pay within the applicable time period, then this Agreement shall not be suspended. If CONSORTIUM fails to cure such failure within the applicable time period, then CONTRACTOR, upon notice to CONSORTIUM, may suspend this Agreement for up to thirty (30) days (or such longer period as the Parties may mutually agree in writing). If CONSORTIUM does not cure its failure to pay during the suspension period (regardless of whether CONTRACTOR discontinues work during such suspension period), then CONTRACTOR, upon notice to CONSORTIUM, may terminate this Agreement. Upon such termination, CONTRACTOR shall receive payment pursuant to Subparagraph 37.3. If CONSORTIUM cures its failure to pay during the suspension period, CONTRACTOR shall not terminate this Agreement, but the Parties will negotiate an adjustment to the schedule, which shall generally reflect the period of the suspension on a day-for-day basis. 36. TERMINATION FOR IMPROPER CONSIDERATION: 36.1 CONSORTIUM may, by written notice to CONTRACTOR, immediately terminate this Agreement if it is found that consideration, in any form, was offered or given CalSAWS Amended, Restated and Revised LRS Agreement 1832361.1 14448-005 Page 25 by CONTRACTOR or any Subcontractor, either directly or through an intermediary, to any CONSORTIUM officer, employee or agent with the intent of securing this Agreement or securing favorable treatment with respect to the award, amendment, or extension of this Agreement or the making of any determinations with respect to CONTRACTOR’s or any Subcontractor’s performance pursuant to this Agreement. In the event of such termination, CONSORTIUM shall be entitled to pursue the same remedies against CONTRACTOR as it could pursue in the event of default of CONTRACTOR. 36.2 CONTRACTOR shall immediately report any attempt by a CONSORTIUM officer or employee to solicit such improper consideration. The report shall be made to the San Bernardino County Auditor-Controller/Treasurer/Tax Collector. 36.3 Among other items, such improper consideration may take the form of cash, discounts, services, the provision of travel or entertainment, or tangible gifts. 37. TERMINATION FOR CONVENIENCE: 37.1 This Agreement, including the hosting services, may be terminated, in whole or in part, from time to time, when such action is determined by CONSORTIUM to be in its best interest, and when CONSORTIUM has received: (i) federal and State approval for such termination; and (ii) assurance of the availability of federal and State funds to cover the payments set forth in Subparagraph 37.3. Termination of Work hereunder shall be effected by delivery to CONTRACTOR of a notice of termination specifying the extent to which performance of Work is terminated and the date upon which such termination becomes effective. The date upon which such termination becomes effective shall be no less than thirty (30) days after the notice is sent, provided that in the event CONSORTIUM has purported to terminate this Agreement for default by notice pursuant to Paragraph 35 (Termination for Default) and it has later been determined that CONTRACTOR was not in default, no additional notice shall be required upon such determination. CalSAWS Amended, Restated and Revised LRS Agreement 1832361.1 14448-005 Page 26 37.2 After receipt of a notice of termination, and except as otherwise directed by CONSORTIUM, CONTRACTOR shall take the following actions in anticipation of the payments set forth in Subparagraph 37.3: (A) Stop Work under this Agreement on the date and to the extent specified in such notice; (B) Transfer to CONSORTIUM, to the extent not previously transferred to CONSORTIUM, title or a license to all LRS Application Software, CalSAWS Software and CONSORTIUM Materials pursuant to the terms of this Agreement; (C) For each Commercially Available Software component: (i) transfer to CONSORTIUM, to the extent not previously transferred to COUNTY, title to such Commercially Available Software component; or (ii) license to CONSORTIUM, to the extent not previously licensed to CONSORTIUM, a license to such Commercially Available Software component, pursuant to the terms of this Agreement; (D) Transfer and deliver to CONSORTIUM copies of all LRS Application Software, Program Data, and CONSORTIUM Repository pursuant to the terms of this Agreement; (E) Transfer and deliver to CONSORTIUM all CONSORTIUM Materials and other completed Work and Work in process; and (F) Complete performance of such part of the Work as shall not have been terminated by such notice. 37.3 In the event that CONSORTIUM terminates this Agreement as provided in this Paragraph 37, then CONSORTIUM will pay CONTRACTOR for: (i) all Work approved by CONSORTIUM pursuant to Subparagraph 4.2 (CONSORTIUM Approval of Work), and (ii) all Withhold Amounts, if any, for such Work. Nothing in this Paragraph 37 shall be deemed to prejudice any right of CONTRACTOR to make a claim against CONSORTIUM in accordance with applicable law and CalSAWS Amended, Restated and Revised LRS Agreement 1832361.1 14448-005 Page 27 regular CONSORTIUM procedures for payment for Work performed through the effective date of CONSORTIUM’s termination of this Agreement for convenience.

For purpose of this Section 37.3 as applied to the CalSAWS Project, the CONSORTIUM Executive Director shall not have unilateral discretion to determine CONTRACTOR’s costs for compensation. The applicable facts will be established by the mutual agreement of the Parties. In the event that the applicable facts cannot be determined by mutual agreement, the Parties will utilize the dispute resolution process set forth in Section 48. If the termination is partial and either increases or decreases CONTRACTOR’s costs of performing, or causes changes to the schedule for, the continued portion of the Work, CONTRACTOR and CONSORTIUM will negotiate in good faith for an adjustment pursuant to Subparagraph 5.2.2 of the price and schedules for the continued portion of the Work. 37.4 For a period of five (5) years after final settlement under this Agreement, CONTRACTOR shall make available to CONSORTIUM, at all reasonable times, all its books, records, documents, or other evidence bearing on the termination of Work hereunder.

The provisions of this Paragraph 65 shall be inserted into any such subcontract agreement and a copy of the Jury Service Program shall be attached to the agreement. CalSAWS Amended, Restated and Revised LRS Agreement 1832361.1 14448-005 Page 42 If CONTRACTOR is not required to comply with the Jury Service Program when this Agreement commences, CONTRACTOR shall have a continuing obligation to review the applicability of its “exception status” from the Jury Service P rogram, and CONTRACTOR shall immediately notify LA COUNTY if CONTRACTOR at any time either comes within the Jury Service Program's definition of “Contractor” or if CONTRACTOR no longer qualifies for an exception to the Jury Service Program. In either event, CONTRACTOR shall immediately implement a written policy consistent with the Jury Service Program. COUNTY may also require, at any time during the term of this Agreement and at its sole discretion, that CONTRACTOR demonstrate to LA COUNTY’s satisfaction that CONTRACTOR either continues to remain outside of the Jury Service Program’s definition of “Contractor” and/or that CONTRACTOR continues to qualify for an exception to the Jury Service Program. CONTRACTOR’s violation of this Paragraph 65 may constitute a material breach of this Agreement. In the event of such material breach, LA COUNTY may, in its sole discretion, terminate this Agreement and/or bar CONTRACTOR from the award of future LA COUNTY contracts for a period of time consistent with the seriousness of the breach. This provision is inapplicable prospectively after the Restatement Effective Date. 66.

ATTESTED: March 19, 2019 David Twa, County Administrator and Clerk of the Board of Supervisors By: Jami Napier, Deputy cc: D.3 To:Board of Supervisors From:Kathy Gallagher, Employment & Human Services Director Date:March 19, 2019 Contra Costa County Subject:Approve and Adopt CalSAWS Joint Exercise of Powers Agreement FISCAL IMPACT: The estimated increased County cost in FY 19/20 for California’s Statewide Automated Welfare Systems (CalSAWS) planning activities is $12,000. This cost has been included in the Employment and Human Services Department’s (EHSD) recommended budget. Costs for the County’s current welfare case management system, CalWIN, are included annually in EHSD’s budget and represent a 4% share of the total Federal/State/County system costs. Total County costs for CalSAWS Design, Development and Implementation, and for the Maintenance and Operations over the course of the project are still being estimated at the State and Federal level. Costs for the new system will be partially, or entirely, offset by current investments in the CalWIN system. BACKGROUND: The Statewide Automated Welfare Systems (SAWS) are the case management systems that are currently managed and operated by two consortia representing the 58 California counties. The SAWS support the delivery of services to applicants and beneficiaries of the State of California’s public assistance programs and other County programs. These systems automate program enrollment, eligibility determination, benefits payroll, reporting, and other case management functionality. The SAWS provide support for the administration of programs including Medi-Cal, California Work Opportunity & Responsibility to Kids/Temporary Aid to Needy Families (CalWORKs/TANF), CalFresh/Supplemental Nutrition Assistance Program (SNAP), Cash Assistance Program for Immigrants (CAPI), Foster Care, Refugee Cash Assistance (RCA), Kinship Guardianship Assistance Program (KinGAP), California Food Assistance Program (CFAP), General Assistance/General Relief (GA/GR), Adoption Assistance, and other health and human services programs or subprograms. Currently, there are three separate SAWS in California, managed by two separate consortia of counties, as follows: Welfare Client Data Systems (WCDS Consortium) maintains and operates the California Work Opportunity and Responsibility to Kids Information Network (CalWIN) system supporting 18 counties, including Contra Costa County. California Automated Consortium Eligibility System (CalACES Consortium), established in 2017, maintains and operates the Los Angeles Eligibility, Automated Determination, Evaluation and Reporting (LEADER) Replacement System (LRS) supporting Los Angeles County, and the Consortium IV (C-IV) system supporting the other 39 counties. For the State to continue to receive Federal Financial Participation for the SAWS, and to comply with State and Federal technology architecture standards, the Centers for Medicare and Medicaid Services and the United States Department of Agriculture (USDA) Food and Nutrition Services require that California implement a single SAWS system by the end of 2023. To comply with these obligations, the 40 county members of the CalACES Consortium and the 18 county members of the WCDS Consortium will join together to create a single statewide system managed by a CalSAWS Joint Powers Authority, known as the CalSAWS Consortium. Establishment, Purpose, and Structure of the Joint Powers Authority To transition to the CalSAWS single system by 2023, California requested and received funding to conduct planning to determine the level of effort and cost to move to a single system. As part of that planning effort, the California counties formed the CalSAWS Leadership Team to finalize a formal CalSAWS Consortium governance structure. The Contra Costa County EHSD Director is a member of this team. This Leadership Team, in conjunction with California Welfare Directors Association, California Department of Social Services, Department of Health Care Services, and Office of Systems Integration, provided guidance and oversight to the CalACES and WCDS Consortia Executive Directors in their preparation of the CalSAWS Consortium governing documents. A work group of several County Counsels assisted in the development of the governance documents, which include the Joint Exercise of Powers Agreement, and the Memorandum of Understanding to be executed between the Consortium and each individual county. The CalSAWS Leadership Team worked with County Counsel representatives in the preparation of the governing documents and the County Counsel offices of all 58 counties reviewed and provided input for these documents. It is anticipated that all 58 County Counsels will approve these documents as to form. The Joint Exercise of Powers Agreement defines the purpose, powers and general provisions governing the CalSAWS Consortium. The CalSAWS Consortium (“Consortium”) is formed in accordance with the provisions of the California Government Code, commencing with Section 6500. The purpose of the Consortium is to design, develop, and implement the CalSAWS single statewide system, and conduct the ongoing operation and maintenance of the current SAWS systems until they are phased out. The Consortium is organized into a governance structure of six (6) regions comprised of one or more counties. Each County will have one Consortium Member Representative with the exception of Los Angeles, which has three representatives to reflect its proportion of the state population. This board order requests the Employment and Human Services Department Director be appointed as Contra Costa County’s Member Representative. Should the current EHSD Director vacate their County position, the member seat will automatically be deemed vacant and automatically filled by the interim or permanent individual assuming this Director position. The CalSAWS Consortium will be governed and administered by a 12 voting member Board of Directors, with twelve (12) county Welfare Directors appointed by Member Representatives from their region. The number of Directors from each region is based upon aided person counts in public assistance programs in each region. Regions 1 and 4 will have two Directors each, Regions 2 and 3 will have one Director each, and Regions 5 and 6 will have three Directors each. Each Director on the 12-member board has one vote. Contra Costa County will be a member of Region 1, which includes a total of 12 Bay Area and Coastal counties (8 from the WCDS Consortium and 4 from the CalACES Consortium). The San Bernardino County Treasurer will be the Treasurer of the Consortium. Indemnification Obligations The Joint Exercise of Powers Agreement requires the CalSAWS Consortium to indemnify and defend each of its County members, including Contra Costa County, from all claims, losses, damages, and/or liability arising from the Consortium’s acts, errors, or omissions. The Agreement also requires each of the member counties to defend and indemnify each of the other member Counties from any liability, claim, or judgement for injury or damages caused by any negligent or wrongful act or omission of the indemnifying member related to the performance of the Agreement. MOU Between Contra Costa County and the CalSAWS Consortium The CalSAWS Consortium will operate pursuant to a Memorandum of Understanding (MOU) with each member county. The MOU establishes the obligations of each county regarding SAWS vendor agreements, equipment, personnel, and other resources in fulfillment of the CalSAWS Consortium’s mission and objectives. The MOU defines what expenses each contracting party will be responsible for in the course of developing, implementing and maintaining the system. This includes commitment that the Consortium will reimburse personnel expenses. Federal Approvals and Timeline Final Federal approval from the USDA Food and Nutrition Services and the Department of Health and Human Services Centers for Medicare and Medicaid Services has been received approving and accepting the Implementation Advance Planning Document (IAPD) for FFY 2019 through FFY 2020. With this approval and funding authorization, the CalSAWS planning and implementation project officially launched on March 4, 2019 and is currently planned to be completed and receive final federal acceptance no later than June 30, 2023. It is expected that Contra Costa will migrate to the new CalSAWS system in 2022. Pending approval of the Boards of Supervisors of each of the 58 Counties, the Joint Exercise of Powers Agreement will become effective on June 28, 2019. CONSEQUENCE OF NEGATIVE ACTION: Contra Costa County would still be mandated to migrate to the new CalSAWS system, but would do so without a voice in the process. The County would not become a member of the CalSAWS Consortium and would not be able to access Federal funding for the CalSAWS Planning and Implementation requirements.

BACKGROUND: (CONT'D) if the Board of Supervisors does not appropriate funds in a fiscal year for payments due to Tanium under the agreement Under the agreement, the County is obligated to indemnify Tanium for third party claims arising out of County data in the system that violates third party’s rights, or use of the software in a manner prohibited or restricted by the agreement, or violation of applicable law, or County’s breach of the vendor’s acceptable use policy. The agreement limits Tanium’s liability to the County to the amount of fees paid by County in the twelve months preceding the events giving rise to the claim CONSEQUENCE OF NEGATIVE ACTION: If this agreement is not approved, the County will be unable to move forward with this cloud-based solution and will negatively impact DoIT’s network administrators’ ability to manage vulnerabilities quickly and efficiently. RECOMMENDATION(S): CONTINUE the emergency action originally taken by the Board of Supervisors on November 16, 1999 regarding the issue of homelessness in Contra Costa County. FISCAL IMPACT: There is no fiscal impact for this action. BACKGROUND: On November 16, 1999, the Board of Supervisors declared a local emergency, pursuant to the provisions of Government Code Section 8630 on homelessness in Contra Costa County. Government Code Section 8630 requires that, for a body that meets weekly, the need to continue the emergency declaration be reviewed at least every 60 days until the local emergency is terminated. The Board of Supervisors last reviewed and continued the emergency declaration on January 11, 2022. Nevertheless, with the continuing high number of homeless individuals and insufficient funding available to assist in sheltering all homeless individuals and families, the emergency situation still exists and it is, therefore, appropriate for the Board to continue the declaration of a local emergency regarding homelessness.

FISCAL IMPACT: No impact to the General Fund. The Library budget will be adjusted to reflect the estimated reduction in revenue of $20,000 due to the elimination of print charges. BACKGROUND: The County Librarian and County Library Commission are recommending changes to the library fines and charges schedule policy. The County Librarian requests the Board of Supervisors to adopt the new Contra Costa County Library Fines and Charges Schedule that will no longer include charges for the first ten (10) pages of black and white prints from public computing stations. Black and white printing of 11 or more pages will continue to be $.15 per page. Color printing will continue to be $.50 per page and will apply to all pages printed. On October 13, 2020, the Board of Supervisors approved a waiver of print charges on a limited basis for the duration of the Public Health Emergency. The program allowed the public to email documents to library staff to print or to bring documents to the library to be scanned and printed. The service was limited to 10 black and white double-sided pages per day, per person. The program fulfilled a community need of providing printing and scanning of documents. The pilot program was launched in communities with high need: Antioch, Bay Point, Concord, Hercules, Pittsburg, and San Pablo. After a successful test, the program was expanded to all libraries. The Library proposes making this permanent in the Library Schedule of Fines & Charges effective March 1, 2022. CONSEQUENCE OF NEGATIVE ACTION: Contra Costa County residents, especially those in low income areas, who do not have access to a printers will experience significant barriers to having their documents printed.

FISCAL IMPACT: None. BACKGROUND: On December 14, 2021 the Board of Supervisors approved the Library Closure List for 2022. As in years past, one of the closed days was for the library's annual All Staff Training Day. Based on feedback from presenters and staff who are uncomfortable attending an in-person event due to the ongoing COVID-19 pandemic, the All Staff Training day for 2022 will be cancelled.

ARPA was signed into law on March 11, 2021 by President Biden. The ARPA is a broad and far-reaching funding package totaling $1.9 Trillion, which provides direct stimulus to taxpayers, advances on child tax credit payments, direct allocations to State and Local governments as well as a myriad of funding augmentations and competitive grant programs administered by federal agencies. A summary of the ARPA, including national funding figures, is included as Attachment A for reference. The Board directed the County Administrator to provide ARPA revenue and expenditure updates on a quarterly basis. In preparation for the August 3, 2021 public workshop, the County Administrator worked with County departments to identify $317,327,304 in known ARPA revenue coming to the County. Of that $317 million, $127,606,231 had been received by the County, which was composed of two of the largest ARPA funding streams; specifically, the Coronavirus State and Local Fiscal Recovery Fund (CSLFRF) in the amount of $112,029,451, and a second allocation of $15,576,780 of Emergency Rental Assistance Program (ERAP) funds. The second tranche of CSLFRF will be distributed to the County in May 2022 in the amount of $112,029,451. In addition to CSLFRF, County departments identified $71,605,012 of Emergency Rental Assistance Program 2 (ERAP 2) allocation, $12,000,000 of HOME Investment Partnerships allocation, $3,355,250 of ARPA Funding for Health Centers allocation, $2,508,139 of Substance Abuse Prevention and Treatment Block Grant (SABG) allocation, $2,300,000 of ARPA Head Start allocation and $1,500,000 of ARPA Public Health workforce grant funds. At the conclusion of the August 2021 public workshop, the Board directed the full $112 million allocation of Year 1 CSLFRF funding to the Health Services Department to defray the cost impacts of COVID-19 response activities. Subsequently, on January 25, 2022, the Board acknowledged that the fiscal year 2022/23 Recommended Budget will include $53 million of Year 2 CSLFRF funding in the Health Services Department budget. In addition, the Board postponed allocation of the remaining $59 million of Year 2 CSLFRF funding until January 2023. Today's agenda item includes the fiscal year 2021/22 2nd Quarter Report on ARPA, reflecting information through December 31, 2022, which is included as Attachment B. The next quarterly ARPA report will be provided on the May 10, 2022 consent agenda. CONSEQUENCE OF NEGATIVE ACTION: The fiscal year 2021/22 2nd Quarter Report for ARPA will not be formally accepted by the Board of Supervisors.
