I. FINDINGS A. Growth Management Performance Standards 1. Traffic: Policy 4-c under Growth Management Program (GMP) requires a traffic impact analysis be conducted for any project that is estimated to generate 100 or more AM or PM peak-hour trips based upon the trip generation rates as presented in the Institute of Traffic Engineers (ITE). A project generating less than 100 peak-hour trips generally will not create or exacerbate any current traffic problems. The project provided a Transportation Impact Analysis prepared by W-Trans which concluded that the project would generate 10 AM trips and 12 PM trips. Since the proposed development would yield less than 100 peak-hour AM or PM trips, a project-specific traffic impact analysis is not required and the project is assumed to have a less than significant impact on the circulation system in the project vicinity. 2. Water: The GMP requires new development to demonstrate that adequate water quantity can be provided. The subject property currently receives water service from the Contra Costa Water District (CCWD), and the district has stated that water service is available for the project as the entire site is within the water districts service area. 3. Sanitary Sewer: The GMP requires new development to demonstrate that adequate sanitary sewer service is available. The project site currently receives sanitary sewer service from the Mount View Sanitary District (MVSD) and MVSD sewer mains in the area are available for the project. The district provided a letter stating that the applicant shall submit a sewer permit application with the district for review and approval. 4. Fire Protection: The fire protection standards under the GMP require that a fire station be within one and one-half miles of development in urban, suburban, and central business district, or requires that an automatic fire sprinkler system be installed to satisfy this standard. The project site is within the Contra Costa County Fire Protection District jurisdiction and is located approximately six minute drive time from Contra Costa County Fire Station #14 located at 521 Jones Street in Martinez. The project is required to comply with the applicable provisions of the California Fire Code, the California Residential Code, and Contra Costa County Ordinances that pertain to emergency access, fire suppression systems, and fire detection/warning systems. When it comes time to submit for building permits, the construction drawings would have to be reviewed and approved by the Contra Costa County Fire Protection District. 5. Public Protection: Public protection standards under the GMP require that a Sheriff Facility standard of 155 square feet of station area and support facilities per 1,000 in 49 BOS – March 26, 2024 County File #CDDP21-03031 Findings and COA Page 2 population shall be maintained within the unincorporated area of the County. Based on the United States Census Bureau’s estimate of 2.48 persons per household (between 2017-2021) for Martinez, the project would potentially increase the population by an estimated 89.28 people. Since the project would result in a relatively small change in population, the project would not impact the County’s ability to maintain a Sheriff facility standard of 155 square feet of station area and support facilities per 1,000 members of the population. Thus, the project would not significantly affect the provision of police services to the Martinez area. 6. Parks and Recreation: As the project will add to the County’s population, Condition of Approval (COA) #21 and #22 requires the project proponent to pay applicable Park Impact and Park Dedication in-lieu fees for the new units. These fees, in conjunction with all other Park Dedication fees collected for development within the County, will be used in part to purchase new park land and upgrade existing community parks as determined appropriate by the Board of Supervisors. 7. Flood Control and Drainage: The project is located in Flood Zone X, as designated on the Federal Emergency Management Agency’s Flood Insurance Rate Maps. The project is required to meet collect and convey requirements of the County Subdivision Ordinance Title 9, by constructing the necessary drainage improvements, or obtaining necessary exceptions to the code. The applicant must also comply with the County’s National Pollutant Discharge Elimination System (NPDES) Permit and Stormwater Management and Discharge Control Ordinance, Title 10, for stormwater treatment. With the included exception to Title 9, the new drainage improvements will both meet stormwater discharge requirements for stormwater treatment, while also accommodating all rainwater runoff generated by the project, as required by Title 9. B. Development Plan Findings 1. Required Finding: The proposed project is consistent with the purpose of the zoning district: Project Finding: The purpose of the M-29 Multiple Family Residential (M-29) district is to allow multiple-family residential development to be compatible as much as possible with nearby single-family residential zoning. The project will largely conform to the M-29 District development standards related to setbacks, lot coverage, and other standards. Variances to the development standards meet the intent of the standards, as required by the Variance findings. The project also has submitted a Density Bonus Request and is requesting parking ratios pursuant to Government Code 65915(p) and multiple reduction to development pursuant to Government Code 65915(e). With these requests, the 50 BOS – March 26, 2024 County File #CDDP21-03031 Findings and COA Page 3 proposed project creates a multi-family apartment complex that is a permitted use under 84-26.402(3). 2. Required Finding: The proposed project is architecturally compatible with other uses in the vicinity, both inside and outside the zoning district. Project Finding: Given the density of housing development in the area (townhomes, duplexes, single-family residence), the design does not conflict with the surroundings in building mass or height. The architectural style in this area of the County can be described as a diverse collection of Ranch, Mediterranean, Spanish Revival, and contemporary modern styles. The project’s contemporary design would be comprised of three segments separated by staircase breezeways, joined under one unified flat roof to minimize the overall bulk of the structure. Building design incorporates a rectangular shape with all exterior walls of each level at the same location to create one cohesive building from top to bottom while the open breezeway at each level adds depth and variation to the exterior of the building. The façade of the building will have variation with sandstone color stucco alternating with pearl gray shingle siding. The colors of the building will be designed to compliment the surrounding natural palette of the area. C. Variance Findings: 1. Required Finding: Any variance authorized shall not constitute a grant of special privilege inconsistent with the limitations on other properties in the vicinity and the respective land use district in which the subject property is located. Project Finding for Height: The project had a original request for a 38’-6” height. However, after the County Planning Commission hearing and subsequent meeting with the Board of Supervisor, the applicant agreed to lower the total height of the building. Therefore, the variance request is to allow a 34.25-foot tall building (where 30 feet is the maximum allowed). Given that the height is due to unique topographical characteristics and drainage restrictions, granting of the variance for the building height would not be considered a grant of special privilege. In order to meet drainage requirements that require stormwater to drain to adequate stormwater infrastructure at Windhover Way, the rear of the lot must be padded (i.e., filled with dirt to raise the grade). Currently, the rear of the lot is almost nine feet lower than the frontage (Windhover Way). The project will pad almost nine feet towards the rear to bring the site level and 4’-6” of padding under the building itself. This extensive amount of padding raises the finished grade under the rear of the building, resulting in a height that exceeds the 30-foot standard when measured from natural grade. Complying with the height restriction would present a practical difficulty because the project is required to have drainage improvements due to topography. Additionally, in order to meet the required density of the General Plan 51 BOS – March 26, 2024 County File #CDDP21-03031 Findings and COA Page 4 Land Use Designation for this site, the project was required to add more units, which prompted the height increase. Strict application of the zoning code would present an unnecessary burden on the site by reducing the amount of units on site by eight, which would result in a total of 16 units, which is on the lower end for the General Plan Land Use Designation. For these reasons, the height of the building is not a grant of special privilege inconsistent with the limitations of other properties in the vicinity and respective land use district. Project Finding for Driveway Aisle Width: The variance request is to allow for a 24.5’ driveway aisle width (where 25’ is the minimum required) for a driveway aisle with parking spaces of ninety degrees located on the eastern side of the multi-family apartment building. Granting the variance for the reduced driveway aisle width would not be a grant of special privilege. The irregular flag- shaped property has an approximately 48-foot-wide by 72-foot-long strip of land that extends access to Windhover way. The strip of land presents a unique restriction only applicable to this site. The unique shape unreasonably limits development on the property in a way that the required density is only feasible with reduced driveway aisle width. In order to facilitate and maintain circulation and to allow the site to provide adequate parking spaces, the driveway aisle width needs to be slightly reduced. Complying with the ordinance for driveway aisle width would present a practical difficulty because it would reduce the amount of parking on the site and limit the total developable area. For these reasons, the reduced driveway aisle width is not a grant of special privilege inconsistent with the limitations of other properties in the vicinity and respective land use district. 2. Required Finding: That because of special circumstances applicable to the subject property because of its size, shape, topography, location or surroundings, the strict application of the respective zoning regulations is found to deprive the subject property of rights enjoyed by other properties in the vicinity and within the identical land use district. Project Finding for Height: Given that the additional height is due to unique topographical characteristics and drainage restrictions, granting of the variance for the building height is based on special circumstances. In order to meet drainage requirements that require stormwater to drain to adequate stormwater infrastructure at Windhover Way, the rear of the lot must be raised by padding from approximately 9 feet at the rear property line to 4’-6” underneath the building. Given that the site slopes away from Windhover Way, the building is required to be raised to address drainage issues. Thus, due to these special circumstances, the strict application of zoning regulations would deprive the subject property of rights enjoyed by other properties developed as multiple-family projects. 52 BOS – March 26, 2024 County File #CDDP21-03031 Findings and COA Page 5 Project Finding for Driveway Aisle Width: The variance request is to allow for a 24.5’ driveway aisle width (where 25’ is the required minimum). The irregular flag-shaped property has a 48-foot-wide by 72-foot-long strip of land that extends access to Windhover Way. This unique shape limits the placement and development of a driveway aisle width on the property as there are already numerous other constraints. To provide a driveway aisle for parking spaces to be accessed, the only feasible location is between the parking spaces. The flagged driveway results in additional area on the lot that must be paved in order to reach the larger developable portion of the lot. Thus, a 25’ driveway aisle would not be feasible while also providing parking, open space, covered parking and space for the building. Thus, due to these special circumstances, the strict application of the zoning regulations would deprive the subject property of rights enjoyed by other properties developed as multiple-family projects. 3. Required Finding: That any variance authorized shall substantially meet the intent and purpose of the respective land use district in which the subject property is located. Project Finding for Height: Height limits are applied to provide an orderly residential development pattern and adequate air and light between neighboring development. The 4.25-feet of additional height would substantially meet the intent and purpose of the respective 30-foot height maximum as all building setbacks are met and exceeded. The building would maintain separation from neighboring properties. The variance request will allow for the project to address drainage and topography issues without burdening the applicant. Therefore the height would not have a detrimental effect on the adjoining properties and meet the intent and purpose of the respective land use district. Project Finding for Driveway Aisle Width: The variance request is to allow for a reduced 24.5’ driveway aisle width (where 25’ is the minimum required). The driveway aisle width allows for cars to maneuver in and out of parking spaces. The proposed driveway aisle width is only 0.5’ less than the minimum requirement. Due to site constraints, the project has balanced the need to provide the full driveway aisle width with the need to provide for adequate parking spots and landscaping requirements. The loss of 0.5’ les for a driveway aisle width will not have a detrimental effect on the adjoining properties and meet the intent and purpose of the respective land use district. 4. Findings for Granting an Exception Per Section 92-6.002: Request for an exception from Title 9 Offsite Collect and Convey Diversion requirements (Section 914-2.0040) 1. Required Finding: That there are unusual circumstances or conditions affecting the property. 53 BOS – March 26, 2024 County File #CDDP21-03031 Findings and COA Page 6 Project Finding: The property slopes from the northwest corner to the southeast corner, away and considerably below street grade. There is no storm drain or easement at the lowest corner of the site. On-site drainage facilities will be installed to tie into the existing storm drain on Windhover Way to the west. The storm drain is deep enough to allow for gravity drainage from the stormwater treatment facilities but was not originally intended to accept stormwater runoff from this site. Considering this site’s unusual circumstances and conditions, an exception from the County Ordinance Code prohibition regarding diversions would be required. 2. Required Finding: That the exception is necessary for the preservation and enjoyment of a substantial property right. Project Finding: The diversion of stormwater is necessary to connect the project to stormwater facilities in the area. A connection at the southeast corner of the property is not currently possible, meaning this infill project is not feasible unless the exception is granted. Additionally, as described above, the drainage infrastructure already exists within the Windhover Way right-of-way making this the most appropriate location. 3. Required Finding: That the granting of the exception will not be materially detrimental to the public welfare or injurious to other property in the territory in which the property is situated. Project Finding: Capacity of the downstream drainage system will be verified to ensure it is sufficient to accommodate the additional runoff. Additionally, stormwater would be directed to existing infrastructure used by other properties in the area. Therefore, the exception will not be materially detrimental to the public welfare or injurious to other properties in the territory in which the subject property is situated. The applicant will be required to provide a drainage report to verify the adequacy of the downstream drainage system. If the receiving system is found to be inadequate the applicant shall be required to improve the system to make it adequate. 5. Tree Protection and Preservation Findings: Required Factors for Granting Tree Permit: The Zoning Administrator is satisfied the following factors as provided by County Code Section 816-6.8010 for granting a tree permit have been satisfied:  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. 54 BOS – March 26, 2024 County File #CDDP21-03031 Findings and COA Page 7  Where the arborist or forester report has been required, and the director is satisfied that the issuance of a permit will not negatively affect the sustainability of the resource. The project proposes to remove tree #35, 36, 37 and 38. The project proposes to work within the dripline of tree # 40, 41 and 42. All feasible efforts have been made to retain the maximum number of trees and that development of this project cannot be reasonably accommodated on other parts of the property due to the shape and orientation of the property. The trees are required to be removed in order for the appropriate infrastructure to be built to support a project of this size. Development on this property can not occur without the removal of trees. An arborist report was provided which concluded that the trees to be removed are moderate to low health. California Environmental Quality Act (CEQA) Finding In accordance with CEQA Guidelines, Section 15071 and Section 15072, a Mitigated Negative Declaration/Initial Study (MND) was prepared and published for the project. The 20-day public review period for the MND started on July 11, 2023, and ended on July 31, 2023. Seven public comments were received during the public review period for the MND. The comments received did not specifically challenge the adequacy of the environmental document. Neither the comment nor the staff response to the comment result in any changes to the MND, and the impacts, mitigation measures, and findings of the MND are unchanged. On the basis of the whole record before it, including the MND, and in accordance with Section 15074, the County Planning Commission finds that:  There is no substantial evidence that the project with the proposed mitigation measures will have a significant effect on the environment;  The MND reflects the County’s independent judgement and analysis;  The MND is adequate and complete; and  The MND has been prepared in compliance with the California Environmental Quality Act (CEQA) and the State and County CEQA guidelines. Pursuant to CEQA Section 15097, a Mitigation Monitoring Program has been prepared, based on the identified impacts and mitigation measures in the MND. The Mitigation Monitoring Program is intended to ensure that the mitigation measures identified in the MND are implemented. All mitigation measures are included in the Conditions of Approval for the project. 55 BOS – March 26, 2024 County File #CDDP21-03031 Findings and COA Page 8 II.

Pursuant to Section 822-4.402(a) of the County Ordinance Code, in a residential development of 22 rental units, at least fifteen percent of the rental units shall be developed and rented as inclusionary units. The applicant, owner, and/or developer (Applicant) is required to construct 3.3 inclusionary units for the project. The Applicant has submitted a revised Inclusionary Housing Plan received December 27, 2022, which proposed to construct three inclusionary units within the housing development. Two units will be available to lower- income households (80% Area Median Income (AMI)), and one unit will be available to a very low-income household (50% AMI). The fractional unit of 0.3 would be satisfied with the payment of a partial in-lieu fee. The Applicant submitted a revised density bonus request with their revised inclusionary housing plan received December 27, 2022. As described in the HCI April 19, 2022, memo, the Applicant is eligible for a 24.5% density bonus as the Applicant proposed to build on-site three lower-income units or 13% of the units in the housing development as affordable to lower-income households. For this project, the inclusionary housing units are also the lower income units that qualify the project for a density bonus. The Applicant’s Inclusionary Housing Plan and density bonus request propose a density bonus of 2 units, or a 9% bonus, with one requested concession and various reductions in development standards, bringing the total number of units in the project from 22 to 24. 58 BOS – March 26, 2024 County File #CDDP21-03031 Findings and COA Page 11 Density Bonus – Concession/Incentive Pursuant to Government Code 65915, the Applicant has proposed a housing development that will contain units that comply with Government Code 65915(b)(1)(A) and may request one concession/incentive for providing 13 percent of the total units of a housing development for lower-income households within the development. For use of the one concession, the Applicant requested reduced open space requirement pursuant to Government Code 65915(d). Additionally, the Applicant has requested parking ratios based on Government Code 65915(p) for a reduced parking requirement. The request also includes reductions in development standards pursuant to Government Code 65915(e) for reduced parking stall sizes, reduced parking setbacks and reduced covered parking. The County accepted the Applicant’s request for reductions in development standards for the following: Density Bonus – Parking Ratio  Parking ratios pursuant to 65915 (p).  1 Bedroom Units = 1 off-street parking space (where 1.5 spaces are required) 2 Bedroom Units = 1.5 off street parking space (where 2 spaces are required) Density Bonus – Reduction of Development Standards  Parking stall sizes of 9 feet x 18 feet and 9 feet x 17 feet (where 9 feet x 19 feet is required)  Front Parking setbacks of 17.5 feet (where 25 feet minimum is required).  Side Parking setbacks of 2 feet (where 20 feet minimum is required).  16 total covered parking (where one-half of the required spaces shall be covered). The County accepted the Applicant’s request for one concession, as follows:  Open space requirement of 20% (where the open space requirement is 25% of land area, with 75% of that area landscaped) Inclusionary Housing and Density Bonus Developer Agreement 12.

The bond shall include the amount of the approved cost estimate, plus a 20% inflation surcharge. C. Initial Deposit for Processing of Security: Prior to the removal or work within the dripline of trees or CDD stamp-approval of plans for issuance of building permits (e.g. demolition, grading or building), whichever occurs, the applicant shall provide a cash or surety bond that is acceptable to CDD, the County ordinance requires that the applicant pay fees to cover all staff time and material costs for processing the required security. At the time of submittal of the security, the applicant shall pay an initial deposit of $200.00. D. Duration of Security: The security shall be retained by the County for a minimum of 12 months and up to 24 months beyond the completion of the tree alteration improvements (i.e., date of final inspection). After the final inspection has been completed, the applicant shall submit a letter to the CDD, composed by a consulting arborist, describing any construction impacts to trees intended for preservation. As a prerequisite of releasing the bond between 12- and 24- months, the applicant shall arrange for the consulting arborist to inspect the trees and to prepare a report on the tree’s health. The report shall be submitted to the CDD for review, and it shall include any additional measures necessary for preserving the health of the trees. 29.

Prior to the removal of any trees the project proponent shall hire a certified consulting arborist to be on-site. The contract shall identify the arborist, field schedule, and contact information. The Arborist must review all plans for pre-construction treatment, demolition, grading, drainage, utility, and landscape with irrigation. Prior to issuance of a grading and/or building permit, a copy of the contract must be submitted to CDD for review. 31. The project’s perimeter security fence will serve as the Tree Protection Zone. No grading, excavation, construction, or storage of materials should occur outside the project limit. 32. Off-site trees to be preserved may require pruning to provide clearance for demolition, grading and construction. Tree care firm providing the pruning shall be a State of California Licensed Tree Contractor (C61/D49). All pruning shall be done by Certified Arborist or Certified Tree Worker in accordance with the latest edition of the Best Management Practices for Pruning (International Society of Arboriculture) and the American National Standard for Tree Care Operations (Z133.1) and Pruning (A300). 67 BOS – March 26, 2024 County File #CDDP21-03031 Findings and COA Page 20 33. Tree(s) to be removed that have branches extending into the canopy of tree(s) to remain shall be removed by a Certified Arborist or Certified Tree Worker and not by the demolition contractor. The Certified Arborist or Certified Tree Worker shall remove the trees in a manner that causes no damage to the tree(s) and understory to remain. 34. Trees to be removed shall be felled to fall away from TREE PROTECTION ZONE and avoid pulling and breaking roots of off-site trees to remain. If roots are entwined, the Consulting Arborist may require first severing the major woody root mass before extracting the trees. 35. All tree work shall comply with the Migratory Bird Treaty Act as well as California Fish and Wildlife code 3503-3513 to not disturb nesting birds. To the extent feasible tree pruning and removal should be scheduled outside of the breeding season. Breeding bird surveys should be conducted prior to tree work. Qualified biologists should be involved in establishing work buffers for active nests. Tree Protection During Construction 36. Any approved grading, construction, demolition, or other work within 5-ft of the TREE PROTECTION ZONE near tree #39 must be monitored by the Consulting Arborist. 37. Any root pruning that will occur within 5-ft. of the Tree Protection Zone near tree #39 shall receive prior approval and may be supervised by the Consulting Arborist. Roots should be cut with a saw to provide a flat and smooth cut. Removal of roots larger than 2” in diameter should be avoided. 38. If roots 2” and greater in diameter are encountered during site work and must be cut to complete the construction, the Consulting Arborist must be consulted to evaluate effects on the health and stability of the tree and recommend treatment. 39. 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.

Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code section 21080.3.1? If so, is there a plan for consultation that includes, for example, the determination of significance of impacts to tribal cultural resources, procedures regarding confidentiality, etc.? A Notice of Opportunity to Request Consultation was sent on May 24, 2023, in accordance with section 21080.3.1 of the California Resources Code to the Wilton Rancheria and Confederated Villages of Lisjan Nation, the two California Native American tribes that have requested notification of proposed projects. Pursuant to section 21080.3.1(d), there is a 30-day time period for the Confederated Villages of Lisjan and the Wilton Rancheria to either request or decline consultation in writing for this project. Staff did not receive a request for consultation in response. Therefore, consultation with Native American tribes has not occurred in relation to this project. Environmental Factors Potentially Affected Without mitigation, the environmental factors checked below would have been potentially affected by this project. Upon incorporation of the mitigation measures identified in the following pages it has been found that the project will not result in any impacts to the environment.

I find that, although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the 107 4 project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated" impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR, including revisions or mitigation measures that are imposed upon the proposed project. _____________________________ ____________________ Everett Louie Date Planner II Contra Costa County Department of Conservation & Development Everett Louie 7/11/2023 108 DRAFT ENVIRONMENTAL CHECKLIST 5 Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 1. AESTHETICS – Except as provided in Public Resources Code Section 21099, would the project: a) Have a substantial adverse effect on a scenic vista? b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic building within a state scenic highway? c) In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage points.) 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? SUMMARY: a) Less Than Significant Impact: The Open Space Element of the County General Plan identifies major scenic ridges and waterways within the County as shown in Figure 9-1. The project site is located more than 3 miles to the east of the nearest scenic ridgeway. The subject property is not located near a major scenic resource and will therefore have a less than significant adverse effect on a scenic vista. b) Less Than Significant Impact: Figure 5-4 (Scenic Routes Plan) of the Contra Costa County Transportation and Circulation Element identifies the roadways which form the Countywide scenic routes plan. The project site is bounded by Pacheco Blvd to the south and Windhover Way to the west. The nearest scenic highway is Highway 4 which is approximately 1.30 miles to the south of the project site. Highway traffic is not visible from the site. Since the subject property is not visible from a state scenic highway and is void of any structures (the project site is vacant and covered in shrubs), the project would not substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway. c) Less Than Significant Impact: The vacant property site is located within the Multiple-Family Residential (M-29) zoning district. Generally speaking, the intent of the M-29 zoning district is to provide for residential infill development at a density which is supportive of the surrounding area. In general, the project has been designed pursuant to the guidelines for development within the M-29 zoning district. The project has been designed to be compatible with the existing residential development in the area, including orienting the main entrance towards the Windhover Way frontage. Surrounding uses include single-family residences to the north and south, a 13-unit townhouse development to the east and a 12-unit apartment complex to the northeast. The project has been reviewed for compliance with the M-29 zoning district 109 DRAFT 6 standards, which included the review of the preliminary landscape design that has been submitted with the application. The project proposes to enhance the scenic quality of the site, turning it from a vacant lot with overgrown vegetation to an urban use with landscaping. The final landscape plan must be reviewed by staff upon project approval and prior to applying for building and/or grading permits. Therefore, the project would not conflict with any applicable zoning and/or other regulations governing scenic quality. d) Less Than Significant Impact With Mitigation Incorporated: The project site is located in an urbanized area. However, the site itself is vacant and would introduce new lighting as part of the project design. As required by the Off-Street Parking ordinance, the proposed project will include the installation of four downward-oriented LED streetlight-style lights to be located near the carport to illuminate the parking areas and to allow for safe circulation around the subject property during times of low natural light. The applicant has submitted a preliminary lighting plan that details the location and type of proposed exterior lighting. The lighting plan indicates that the location of the lights will be minimally located near residences off-site. Additionally, the potential for light spillover is limited due to the proposed landscaping which includes trees, a new stone masonry fence and an existing wood fence. The following mitigation measure shall ensure that all outdoor lighting is directed downward and positioned away from adjacent properties and streets, reducing such impacts to a less than significant level. Potential Impact: Project lighting could spill off-site and result in a potentially significant adverse environmental impact due to substantial new light and glare on neighboring properties. Thus, the following mitigation measure would ensure such impacts from project lighting would have a less than significant impact on nighttime views. Mitigation Measure Aesthetics 1: Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, whichever occurs first, a lighting plan shall be submitted to the (CDD) for review and approval. The lighting plan shall provide the specifications of the proposed light post as shown on the approved plans. All outdoor lighting shall be directed down and screened away from adjacent properties and public/private right-of-way to prevent glare or excessive light spillover.

AGRICULTURAL AND FOREST RESOURCES – Would the project: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non- agricultural use? b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g)? d) Result in the loss of forest land or conversion of forest land to non-forest use? e) Involve other changes in the existing environment, which due to their location or nature, could result in conversion of farmland, to non-agricultural use? SUMMARY: a-e) No Impact: The project site is located within the Multiple-Family Residential (M-29) zoning district. The parcel is within an “Urban and Built-Up Land” area as shown on the California Department of Conservation’s Contra Costa County Important Farmland 2018 map. Neither the subject property, nor those in the vicinity are zoned for agricultural use nor does the site contain farmland designated “Prime”, “Unique”, or of “Statewide Importance”. The site is not under a Williamson Act contract with the County. Additionally, the project site is not considered forest land as defined by California Public Resources Code Section 12220(g) or timberland as defined by California Public Resources Code Section 4526. Development of a vacant lot that is not being used for any agricultural use and turning it into a residential project would not involve substantial changes to the existing urban environment. Furthermore, the project site is located in an area of the County that is urbanized and contains uses which include residential, commercial and mixed use. Therefore, the project will have no impact on agricultural or forest resources, will not convert Prime Farmland, unique Farmland or Farmland of Statewide importance to a non-agricultural use, will not result in the conversion or loss of forest resources and will not contribute indirectly to the conversion of adjacent farmland.

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? SUMMARY: a) Less Than Significant Impact: Contra Costa County is within the San Francisco Bay air basin, which is regulated by the Bay Area Air Quality Management District (BAAQMD) pursuant to the Bay Area 2017 Clean Air Plan. The purpose of the Clean Air Plan is to bring the air basin into compliance with the requirements of Federal and State air quality standards and to protect the climate through the reduction of criteria pollutants and greenhouse gases. The CEQA Guidelines support lead agencies in analyzing air quality impacts. If, after analysis, the project’s air quality impacts are found to be below the significant thresholds, then the air quality impacts may be considered less than significant. The potential air quality impacts for this project were evaluated using the BAAQMD 2017 CEQA guidelines screening criteria. Pursuant to these guidelines, if a project does not exceed the screening criteria size it is expected to result in less than significant impacts to air quality. The operational criteria pollutant screening size for the land use type “Apartment, low-rise” is 240 dwelling units, and the construction-related screening size is 78 dwelling units. The proposed 24 dwelling unit apartment complex is below the residential screening criteria for the low-rise apartment complex for both operational (i.e., occupancy of the residential units) and construction-related pollutants. Furthermore, the screening criteria developed by BAAQMD generally represent new developments on greenfield sites. The proposed project is proximate to regional transit service and is considered an infill project in the otherwise developed, surrounding area of Martinez. The County’s Climate Action Plan (CAP) is designed to reduce local greenhouse gas (GHG) emissions while improving community health consistency with the BAAQMD’s guidance on preparing a qualified GHG reduction strategy and State assembly Bill (AB) 32 GHG reduction targets. To assist staff and developers with implementation of the GHG reduction strategy, the CAP includes a development checklist (Appendix E) with strategies for project consistency with the CAP. Such strategies include the installation of high-efficiency appliances, insulation, 112 DRAFT 9 electric vehicle (EV) charging stations, and locating new development within one half mile of a BART, Amtrak, or bus station. Staff will recommend conditions of approval to require verification by staff of the County Building Inspection (BID) and Community Development Division (CDD) of the project’s compliance with Appendix E standards prior to issuance of building permits. Therefore, the potential for the project to conflict with or obstruct implementation of BAAQMD’s Clean Air plan or the County’s Climate Action Plan is less than significant. b) Less Than Significant Impact: As discussed above, the proposed 24-unit apartment complex is less than the criteria pollutant screening size determined by the BAAQMD, and thus would not result in significant emissions of criteria air pollutants during the construction period or during project operation. In addition, by implementing the strategies of the County CAP to reduce GHG emissions, the proposed project would not cause a violation of any air quality standard and would not contribute substantially to any existing or projected air quality violation. Although the proposed project would contribute incrementally to the level of criteria air pollutants in the atmosphere, the project would have a less than significant impact on the level of any criteria pollutant. c) Less Than Significant Impact With Mitigation Incorporated: The project is not expected to cause any localized emissions that could expose sensitive receptors (e.g., nearby residences, schools) to unhealthy long-term air pollutant levels. Construction activities, however, would result in localized emissions of dust and diesel exhaust that could result in temporary impacts to nearby residences, schools, and businesses. Construction and grading activities would produce combustion emissions from various sources including heavy equipment engines, paving, and motor vehicles used by the construction workers. Dust would be generated during site clearing, grading, and construction activities, with the most dust occurring during grading activities. The amount of dust generated would be highly variable and would be dependent on the size of the area disturbed, amount of activity, soil conditions, and meteorological conditions. Although grading and construction activities would be temporary, such activities could have a potentially significant adverse environmental impact during project construction. Consequently, the applicant is required to implement the following mitigation measures, which the BAAQMD recommends to reduce construction dust and exhaust impacts to a less than significant impact. Potential Impact: Future grading and construction activities on the project site would result in localized emissions of dust, diesel exhaust, and combustion emissions that could result in potential, if temporary, air quality impacts to sensitive receptors (e.g., nearby residences, schools) from the project site during project construction. Mitigation Measure Air Quality 1: The following mitigations shall be included on all construction plans and implemented throughout the construction phase of the project: 1. All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day. 2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered. 113 DRAFT 10 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. 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. Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations [CCR]). Clear signage shall be provided for construction workers at all access points. 7. All construction equipment shall be maintained and properly tuned in accordance with manufacturer’s specifications. All equipment shall be checked by a certified visible emissions evaluator. 8. The property owner or site contractor shall post a publicly visible sign with the telephone number and person to contact at the lead agency 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. 9. 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. 10. All contractors shall use equipment that meets the California Air Resources Board' s (CARB) most recent certification standard for off-road heavy duty diesel engines. Implementation of these mitigation measures would reduce the impact on the sensitive receptors during project construction to a less than significant level. d) Less Than Significant Impact With Mitigation Incorporated: The BAAQMD’s 2017 CEQA guidelines indicate that odor impacts can occur from two different situations: 1) siting a new odor source, or 2) siting a new sensitive receptor (e.g., residents). Although not absolute, screening level distances between sources and receptors are utilized by BAAQMD to identify potentially significant impacts from malodors. Depending on the type of land use, the identified screening distance is between one and two miles as shown on Table 3-3 of the CEQA Guidelines. These distances are to be used in conjunction with available complaint history. For example, any odor source with five or more confirmed complaints per year, averaged over three years, is considered to have a significant impact on receptors within the applicable screening distance. Examples of land uses which may potentially generate significant odors include wastewater treatment plants, landfills/composting stations, refineries, chemical plants, etc. The project is not expected to result in other emissions, such as objectionable odors, that would adversely affect a substantial number of people (objectionable odors are typically associated with agricultural or heavy industrial land uses such as refineries, chemical plants, landfills, sewage-treatment plants, etc.) during project operation. However, during construction and grading, diesel powered vehicles and equipment used on site could create localized odors. These odors would be temporary, but there could be a potentially significant adverse environmental impact during project construction due to the creation of objectionable odors. Consequently, the applicant is required to implement Mitigation Measure Air Quality 1 above. 114 DRAFT 11 Implementation of this mitigation would reduce the impact from the creation of objectionable odors to a less than significant level.

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 4. BIOLOGICAL RESOURCES – Would the project: a) 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 Game or U.S. Fish and Wildlife Service? b) 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 Game or U.S. Fish and Wildlife Service? c) 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? d) 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? e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? 115 DRAFT 12 SUMMARY: a) Less Than Significant Impact: The Conservation Element, Figure 8-1 indicates that the project site is not located in a significant ecological area and according to the California Fish and Wildlife Public Access Lands Map, the project site is not indicated to include an area of wildlife or ecological reserve. The location of the project site is surrounded by commercial and residential development and the site currently is vacant with weeds. The site lacks suitable habitat (there are no creeks, wetlands, or riparian habitats located on the subject parcel. Therefore, there will be a less than significant impact on any special status species. b) No Impact: According to the California Department of Fish and Wildlife (CDFW) Public Access Lands map, the project site is not located in or adjacent to an area identified as a wildlife or ecological reserve by the CDFW. According to the Significant Ecological Areas and Selected Locations of Protected Wildlife and Plant Species Areas map (Figure 8-1) of the County General Plan, the project site is not located in or adjacent to a significant ecological resource area. In addition, the property contains no perennial or intermittent streams, creeks or other riparian habitat – Vine Hill Creek is located approximately 900 feet southeast of the subject property. Therefore, the 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 U.S. Fish and Wildlife Service. c) No Impact: Wetlands are defined and identified under Section 404 of the Clean Water Act as “areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.” According to the U.S. Fish and Wildlife Service National Wetlands Inventory map, no wetlands are located at or adjacent to the project site. Therefore, no substantial adverse effects on federally protected wetlands are expected to occur as a result of this project. d) Less Than Significant Impact: The project site does not contain any creeks, wetlands, or riparian habitats located on the subject parcel. It is also not identified in Figure 8-1 of the Conservation Element as an area of significant ecological area or locations of protected wildlife and plant species. As previously mentioned, the project site is a vacant lot surrounded by multiple residential properties and commercial properties. The surrounding area has been disturbed and developed. Therefore, the proposed development is expected to have a less than significant impact on 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 nursery sites, based on existing site conditions and the surrounding land uses. e) Less Than Significant Impact: The project site has several trees that are located within the parcel boundaries. Because the lot is vacant, the trees are currently protected per Chapter 816-6, 116 DRAFT 13 Tree Protection and Preservation Ordinance. The project would remove four code protected trees and work within the dripline of three code protected trees for the construction of the 24- unit apartment building and other various improvements. The applicant is applying for a tree permit which is required prior to any work within the dripline of a code protected tree. The applicant will be required to comply with the conditions of approval which require a tree restitution bond and tree replanting plan. Therefore, as conditioned, the project will have a less than significant impact to tree resources in the County does not conflict with tree preservation policies for Contra Costa County. f) No Impact: The East Contra Costa County Habitat Conservation Plan/Natural Community Conservation Plan (ECCC HCP/NCCP) was adopted by the County in October of 2006. The purpose of this plan is to provide a framework to protect natural resources while streamlining the environmental permitting process for impacts to covered special status species within the rapidly expanding region of Eastern Contra Costa. The proposed project site is located outside of the HCP/NCCP urban development area and thus HCP ordinance no. 2007-53 does not apply to the project. Thus, the project would not conflict with any conservation plan.

CULTURAL RESOURCES – Would the project: a) Cause a substantial adverse change in the significance of a historical resource pursuant to §15064.5? b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? c) Disturb any human remains, including those interred outside of formal cemeteries? SUMMARY: a-c) Less Than Significant Impact with Mitigation Incorporated: The Vacant parcel is not a historical resource pursuant to Section 15065.5 of the CEQA Guidelines because: 117 DRAFT 14 1. It is not a resource listed in, or determined to be eligible by the State Historical Resources Commission, for listening in the California Register of Historical Resources; 2. It is not 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 section 5024.1(g) of the Public Resources Code; and 3. Has not been determined to be historically or culturally significant by a lead agency. In addition, the California Historical Resource Information System, Northwest Information Center (NWIC) has reviewed the project and determined that there is low possibility for the occurrence of unrecorded archeological resources at the site. Thus, no further study of archeological resources is recommended at this time. Additionally, figure 9-2 of the Open Space Element of the General Plan designates the site as “largely urbanized”, which generally means that there is a low probability for encountering archeological resources. The project site is vacant and as such, there are no existing buildings that would be more than 45 years old. The project consists of the construction of an apartment building. The construction work could include trenching, grading and other subsurface work. The proposed project was reviewed by the NWIC, Wilton Rancheria Cultural Preservation Department and Confederated Villages of Lisjan Nation who did not provide any comments of concern. While the project was reviewed by the NWIC and Tribes in the area, there is nevertheless a potential for previously unknown cultural resources to be uncovered during the construction phase of the project. Potential Impact: Although there is no evidence that there is any specific cultural resources known in in the project area, there is nevertheless a potential for previously unknown cultural resources to be uncovered during construction activities requiring excavation or earth movement. The following mitigation measure will ensure that in the event cultural resources are discovered, the proper actions are taken to reduce the adverse environmental impacts to cultural resources to a less than significant level. Mitigation Measure Cultural 1: The following measures shall be implemented during project- related ground disturbance and shall be included on all construction plans. Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the applicant shall provide evidence that the measures and requirements listed below are included on the construction plans. A. All construction personnel, including operators of equipment involved in grading, or trenching activities will be advised of the need to immediately stop work if they observe any indications of the presence of an unanticipated cultural resource discovery (e.g., wood, stone, foundations, and other structural remains; debris-filled wells or privies; deposits of wood, glass, ceramics). If deposits of prehistoric or historical archaeological materials are encountered during ground disturbance activities, all work within 50 feet of the discovery shall be redirected and a qualified archaeologist contacted to evaluate the finds and, if 118 DRAFT 15 necessary, develop appropriate treatment measures in consultation with the County and other appropriate agencies. If the deposits are not eligible, avoidance is not necessary. If eligible, deposits will need to be avoided by impacts or such impacts must be mitigated. Upon completion of the archaeological assessment, a report should be prepared documenting the methods, results, and recommendations. The report should be submitted to the Northwest Information Center and appropriate Contra Costa County agencies. B. If human remains are encountered, work within 50 feet of the discovery shall be redirected and the County Coroner notified immediately. At the same time, an archaeologist shall be contacted to assess the situation. If the human remains are of a Native American origin, the Coroner must notify the Native American Heritage Commission within 24 hours of this identification. The Native American Heritage Commission will identify a Most Likely Descendant (MLD) to inspect the property and provide recommendations for the proper treatment of the remains and associated grave goods. Upon completion of the assessment by an archaeologist, the archaeologist should prepare a report documenting the methods and results and provide recommendations for the treatment of the human remains and any associated cultural materials, as appropriate and in coordination with the recommendations of the MLD. The report should be submitted to the Northwest Information Center and appropriate Contra Costa agencies.

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 6. ENERGY – 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? SUMMARY: 119 DRAFT 16 a) Less Than Significant Impact: In December 2015, a Climate Action Plan (CAP) was adopted by the Contra Costa County Board of Supervisors in order to identify and achieve a reduction in greenhouse gas (GHG) emissions by the year 2020 as mandated by the State under AB32. The design and operation strategies set forth in the CAP for reducing GHG emissions include measures such as installing energy efficient appliances that would also reduce the project’s consumption of energy resources during operation. The residential project will be required to comply with all California Code Title 24 (CalGreen) building energy efficiency standards for an apartment residential building that are in effect at the time that building permit applications are submitted, including any standards regarding the provision of solar energy. If approved, the project will be reviewed under all current energy standards as part of the plan check process. During the plan check process, the proposed development would be subject to the 2022 California Building Standards Code which would include compliance with the energy conservation standards in the Energy Code Section and CalGreen Code Section of the 2022 California Building Standards Code. In addition, the project must also comply with the County’s Water Efficient Landscape Ordinance, which promotes efficient water use. Compliance with all applicable regulations will ensure this development will not have a significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy. During construction, the project may require temporary electrical power. The General Contractor would be required to apply for a temporary power permit from the County and to comply with all applicable building standards for a temporary power connection. Therefore, the impact of construction or operation on electrical energy resources is anticipated to be less than significant. b) Less Than Significant Impact: As mentioned in subsection-a above, the residential project will be required to comply with all California Code Title 24 (CalGreen) building energy efficiency standards for an apartment residential building that are in effect at the time that building permit applications are submitted, including any standards regarding the provision of solar energy. In addition, the design and operation strategies set forth in Table E.1 Standards for CAP Consistency – New Development (Appendix E of the County’s CAP) include measures such as installing energy efficient appliances that would also reduce the project’s consumption of energy resources. Therefore, the project will not conflict with a state or local plan for renewable energy or energy efficiency.

GEOLOGY AND SOILS – Would the 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? SUMMARY: a) i) Less Than Significant Impact: The California Division of Mines and Geology’s Special Publication 42 indicates that the State Geologist is required to delineate “Earthquake Fault Zones” (EFZs) along known active faults in California. The project site is not mapped within an EFZ, nor within an Alquist-Priolo Special Studies Zone. The nearest fault considered active by the CGS is the Concord fault, which passes more than 10.000 feet east of the site. Because the site is not within an official Earthquake Fault Zone, the risk of fault rupture is generally regarded as very low. ii) Less Than Significant Impact: The U.S. Geological Survey (2016) indicates that there is a 72 percent chance of at least one magnitude 6.7 or greater earthquake striking the San Francisco Bay region between 2014 and 2043. With that, the County General Plan Safety Element 121 DRAFT 18 identifies areas that are more or less susceptible to seismic damage as shown in Figure 10-4 Estimated seismic Ground Response. According to Figure 10-4 of the Safety Element, the property is located on Hard Bedrock which has the lowest damage susceptibility. The risk of structural damage from ground shaking is regulated by the building code and the County Grading Ordinance. Codes are intended to keep earthquake risks to an acceptable minimum, and they assume that the ground is stable. Ground failure can result in greater damage. Nevertheless, compliance with the operative provisions of the California Building Code (CBC) along with (i) compliance with the County Grading Ordinance (ii) conservative design and (iii) quality construction are the best means of controlling the life loss and damage potential of earthquakes. Current CBC (2022) requires the use of seismic parameters in the design of all structures requiring building permits. These parameters are based on soil profile types and proximity of faults deemed capable of generating strong/violent earthquake shaking. Design level geotechnical reports routinely provide CBC seismic design parameters, and upon implementation of the mitigations below, adverse effects due to strong seismic ground shaking would be reduced to a less than significant level. iii) Less Than Significant Impact With Mitigation Incorporated: The Safety Element (Figure 10-5 Estimated Liquefaction Potential) of the County General Plan divides lands within the County into three liquefaction potential categories: generally high, generally moderate to low, and generally low. It is used as a “screening criteria” during the processing of land development applications, on a project-by-project basis. By intent, the map is conservative on the side of safety. The project site is entirely or chiefly in an area classified as generally high liquefaction potential. As a result, the project applicant submitted a Geology study that was peer reviewed by the County geologist, Darwin Myers Associate (DMA). The Geology report prepared by GEC Consultants confirmed that the soils are known to be expansive and corrosive and identified undocumented fill on site as an issue of drainage. The County Peer Review Geologist (DMA) reviewed the report by GEC Consultants and concluded that the report of GEC Consultants sufficient to define the geotechnical hazards and to identify mitigation measures. DMA recommends that an updated report be provided prior to issuance of grading or building permits. The focus of the updated report shall be to address the following potential hazards, expansive soils, corrosive soils, siting and design of any required bio-retention facilities and/or other measures that may be recommended to achieve compliance with the clean water requirements of the RWQCB, possible presence of existing undocumented fills and provide seismic parameters based on the California Building Code. Thus, the applicant is required to implement the following mitigation measures: Potential Impact: The project site is within an area where soils are known to be expansive and may be corrosive. Additionally, the geotechnical report prepared by GEC Consultants identified the presence of undocumented fill on the site. Accordingly, staff recommends that the following mitigation measures be incorporated as part of the project to reduce the potential hazards resulting from corrosive soils and other onsite conditions to a less than significant level. 122 DRAFT 19 Mitigation Measure Geology 1: Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the project proponent shall submit a geotechnical report update with the geotechnical review fee in the amount of $3,000, referencing the proposed grading, drainage and foundation plans and providing specific criteria and standards for site grading, drainage and foundation design based on adequate subsurface data, laboratory testing of samples and engineering analysis. The scope of the geotechnical investigation shall address the following potential hazards: (i) expansive soils, (ii) corrosive soils, (iii) siting and design of any required bio-retention facilities and/or other measures that may be recommended to achieve compliance with the clean water requirements of the RWQCB, (iv) possible presence of existing undocumented fills and effective measures to control/ mitigate the settlement hazard, (v) provide seismic parameters based on the adopted California Building Code at the time that a residential building permit is requested. Mitigation Measure Geology 2: Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the geotechnical report update required by Geology 1, above, shall be subject to review by the County’s peer review geologist, and review/approval of the CDD. Improvement, grading and building plans shall carry out the recommendations of the approved report. iv) Less Than Significant Impact: In 1975, the USGS issued photo-interpretation maps of landslides and other surficial deposits in Contra Costa County (that mapping is presented on Page 10-6 in the Safety Element of the County’s General Plan). According to this map, which was prepared by an experienced USGS geologist, the project site is in an area that is not known to have landslides. The County GIS Accela tool also does not identify the site as an area with the possibility of having a landslide. Therefore, it can be concluded that there is a less than significant impact for potential of landslides for this site. b) Less Than Significant Impact: Any areas that are disturbed during construction of the project would be covered by the proposed improvements or landscaping. Since all areas of the property that will be disturbed will be covered by new structures, pervious and impervious surfaces, or landscaping, the potential for soil erosion or loss of topsoil is less than significant. Additionally, a routine provision for grading permits in Contra Costa County is a requirement for submittal of an erosion control plan. This plan is subject to technical review by inspectors of the County Grading Section. Normally there are refinements to erosion control plans as the winter rainy season approaches. Additional details are included in the refined erosion control plan, including such items as provisions for (a) storage of extra erosion control materials on site and (b) monitoring of the performance of disturbed areas on the site during/immediately following significant rainstorms. If erosion control facilities are damaged or failing to perform as intended, the erosion control measures being implemented on the site are refined to correct the deficiency. Implementation of an erosion control plan would further ensure that the project results in less than significant impacts due to erosion or the loss of topsoil. c) Less Than Significant Impact With Mitigation Incorporated: The geotechnical report prepared by GEC Consultants confirmed that the project site is within an area where the soils are known to be expansive and may be corrosive. Additionally, the report confirmed the presence of 123 DRAFT 20 undocumented fill on the site and they identified drainage as a concern. GEC recommended that the drainage should be carefully controlled in the vicinity of the proposed structures and that the undocumented fill must be over-excavated and either (i) incorporated into engineered fill or (ii) if the existing fill contains materials unsuitable for use in an engineered fill, that fill material shall be removed from the site and taken to a suitable facility for disposal. The County’s Peer Review Geologist is concerned that the report was not adequate for the issuance of construction permits without a report update. Potential Impact: The project contains soils that are known to be expansive and may be corrosive. With the addition of undocumented fill, there is potentially significant impact for the project to be located on unstable soil that is not suitable for supporting the proposed improvements. Accordingly, staff recommends that mitigation measures be incorporated as part of the project to reduce the potential hazards resulting from undocumented fill and to perform corrosion potential testing of the graded building pad. Mitigation Measure Geology 3: Following rough grading (but prior to commencement of foundation-related work) the project geotechnical engineer shall perform corrosion potential testing of the graded building pad to determine if special precautions shall be required to avoid damage to improvements that are in contact with the ground (concrete or steel). Mitigation Measure Geology 4: The geotechnical report required by Geology 1 routinely includes recommended geotechnical observation and testing services during construction. These services are essential to the success of the project. They allow the geotechnical engineer to (i) ensure geotechnical recommendations for the 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 BID approval), based on exposed conditions. The monitoring shall commence during clearing, and extend through grading, including testing services during placement of engineered fill, installation of recommended drainage facilities, and foundation related work. A hard 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 during grading, installation of drainage improvements. Similarly, a hard hold shall be placed on the final building inspection for the apartment building, pending submittal of a letter-report from the geotechnical engineer documenting the monitoring services associated with implementation of foundation-related geotechnical recommendations. The geotechnical monitoring shall include pier hole drilling/ foundation preparation work/ installation of drainage improvements (e.g. collection of roof gutter runoff in a closed conduit and conveying it to a suitable discharge point; and possibly installation of a subdrain system around the perimeter of the foundation to control moisture beneath the foundation). 124 DRAFT 21 d) Less Than Significant Impact With Mitigation Incorporated: The soil series that occurs at the site is known to be expansive and may be corrosive. Expansive soils expand when water is added and shrink when they dry out. This continuous change in soil volume can cause structures to move unevenly and crack. Corrosive soils tend to damage concrete and/or uncoated steel that is in contact with the ground. Geotechnical design criteria are needed to avoid/ minimize damage from these adverse soil conditions. A first step is to test the soils to confirm / modify the Soil Survey’s preliminary assessment. In the case of corrosion potential, the soil testing can determine if the soils are corrosive to either steel; or concrete; or to both steel and concrete. The results of that testing can serve to alert the developer and their development consultants (e.g., underground contractor, foundation contractor) of this hazard. The underground contactors can either consider the testing performed to be adequate and act on the results of testing; or they can perform supplemental testing to provide a more complete assessment of this hazard. Potential Impact: As discussed in Section 6(a)(iii) above, the available information indicates a significant risk of damage to structures / improvements due to these adverse soil conditions. Consequently, the applicant is required to implement the following mitigation measure. Mitigation Measure Geology 5: 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, unless additional grading is reviewed and specifically approved by the Building Inspection Division. e) No Impact: The subject property is within an area served by the Mt. View Sanitary District. The proposed development will be connected to the existing public sewer service. The Sanitary District has reviewed the project and has indicated that they would review the sewer improvement plans. There will be no septic system within the project. f) Less Than Significant Impact With Mitigation Incorporated: There are no known paleontological resources located at the project site nor have any unique geological features been identified. Nevertheless, there is always the potential for ground disturbing activity to reveal previously undocumented features. Implementing the mitigation below ensures the project will not significantly impact any such resource that may be uncovered by construction activity at the project site. Potential Impact: Ground disturbance during the project’s construction phase has the potential for disturbing previously unknown unique paleontological resources. In addition to the mitigation measures for Cultural Resources, the following mitigation measures will ensure that in the event unique paleontological resources are discovered, the proper actions are taken to reduce the adverse environmental impacts to unique paleontological resources to a less than significant level. Mitigation Measure Geology 6: Should unique paleontological materials be uncovered during grading, trenching, or other on-site excavation(s), all earthwork within 30 yards of the materials shall be stopped until the Community Development Division (CDD) has been notified, and a 125 DRAFT 22 qualified paleontologist contacted and retained to evaluate the significance of the find, and, if deemed necessary, suggest appropriate mitigation(s).

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 8. GREENHOUSE GAS EMISSIONS – Would the project: a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? SUMMARY: a) Less Than Significant Impact: As discussed in the Air Quality section of this study, the Bay Area Air Quality Management District (BAAQMD) adopted the Bay Area 2017 Clean Air Plan that, in addition to various criteria air pollutants, addresses GHG emissions at a regional scale. The project includes a new 24-unit apartment building. The screening criteria are not thresholds of significance but were developed to provide a conservative indication of whether a proposed project could result in potentially significant air quality impacts. Pursuant to these guidelines, the potential for apartment style buildings would be 78 low-rise apartment dwellings. The project is much lower than the threshold as it proposes 24-units. While the project would generate some GHG emissions, the project’s global climate change is less than “cumulatively considerable’ because the project does not exceed applicable screening criteria, as described 126 DRAFT 23 above. Thus, it can be assumed that the project will have a less than significant impact on the environment regarding greenhouse gas emissions. b) Less Than Significant Impact: Within the 2017 Clean Air Plan is an ambitious GHG reduction target to reduce Bay Area GHG emissions to 80% below 1990 levels by the year 2050. The 2017 control strategy includes all feasible measures to reduce emissions of ozone precursors – reactive organic gases (ROG) and nitrogen oxides (NOx) – and reduce transport of ozone and its precursors to neighboring air basins. In addition, the plan builds upon and enhances BAAQMD’s efforts to reduce emissions of fine particulate matter and toxic air contaminants. BAAQMD’s approach to developing a threshold of significance for GHG emissions is to identify emissions level for which a project would not be expected to substantially conflict with existing California legislation adopted to reduce statewide GHG emissions. For land use development projects, the threshold is 1,100 metric tons per year (MT/yr) of CO2e. If a project would generate GHG levels above the threshold, it would be considered to contribute substantially to a cumulative impact and would be considered significant. The emissions generated as a result of the operational activities of the proposed 24-unit apartment complex will be far less than the significance threshold and will not result in significant levels of GHG that will conflict with any applicable plan, policy, or regulation pertaining to the reduction of GHG. There may be some increase in greenhouse gases as a result of the project, but they would be considered less than significant due to the temporary nature of the construction phase of the project as the project will be required to incorporate energy efficiency measures from the current Title 24 Building Energy Efficiency Standards Code and comply with the CalGreen / Construction & Demolition (C&D) Debris Recovery Program.

HAZARDS AND HAZARDOUS MATERIALS – Would the 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? d) 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 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 in 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? SUMMARY: a-b) Less Than Significant Impact: The proposed project consists of constructing a new 24-unit apartment complex. The proposed improvements and overall project site will be utilized for residential-related improvements and activities. Although small quantities of commercially available hazardous materials may be used for household or common-area cleaning or for landscape maintenance, these materials would not be used in sufficient quantities to pose a threat to human or environmental health. The use of fuels and lubricants, paints, and other construction materials would occur during the construction phase of the project. However, the use and handling of hazardous materials during construction would occur in accordance with applicable federal, state, and local laws, including California Occupational Health and Safety Administration (Cal/OSHA) requirements. With compliance with existing regulations, the project would result in a less than significant impact from construction activities. 128 DRAFT 25 Therefore, the potential for impacts associated with handling, storing, and dispensing of hazardous materials, or through reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials into the environment from project construction or operation would be less than significant. Staff utilized EnviroStor from the Department of Toxic Substances Control’s data system and the tracking system determined that the site is not a site of hazardous waste. No evidence reviewed by staff suggests that the project would be located on a site with hazardous materials pursuant to Government Code Section 65962.5. Therefore, a less than significant impact is expected. c) Less Than Significant Impact: The Las Juntas Elementary School is located approximately 970 feet east while Morello Park Elementary School is located approximately 2684 feet south of the project site. However, due to the proposed use of the building (24-unit apartment), impacts on either school from hazardous substances emitting from the project site, post construction, would be less than significant. No evidence reviewed by staff suggests that the project would include foreseeable conditions involving the likely release of hazardous materials into the environment. The use of construction-related fuels and lubricants, paints, and other construction materials, during the construction period, would occur in accordance with applicable federal, state, and local laws, including California Occupational Health and Safety Administration (Cal/OSHA) requirements. Therefore, the potential impacts from the project to emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste, is considered to be less than significant. d) No Impact: The California Environmental Protection Agency maintains an updated list of Hazardous Waste and Substance Sites (Cortese List). The subject property is not listed on the Cortese List and is not categorized as a hazardous materials site. Therefore, the project will have no impact in this respect. e) No Impact: The project is not located within the vicinity of any public airport or public use airport and will not conflict with an airport land use plan. The nearest airport facility to the project site is the Buchanan Field airport, which is approximately 2 miles southeast of the project site. Thus, the proposed project would not present any safety hazard to airports or excessive noise for people residing or working in the project area. f) Less Than Significant Impact: The subject site fronts Windhover Way, which connects to Pacheco Boulevard, both are County maintained roads. Windhover Way along the project frontage is approximately 36-foot-wide street within a 56-foot right-of-way. There are existing curbs, sidewalk, streetlights, and underground utilities along the frontage. No further widening or frontage improvements are necessary with this development. The project will build a driveway that will connect to Windhover Way from the interior parking lot. The proposed project will not impact any existing communication/utility structures such as power poles or telecommunications towers which may be necessary for an existing emergency response or evacuation plan. Although project construction would primarily occur onsite, the required water main extensions may require temporary road closures or reduced lanes. Additionally, in the event that the alternative drainage plan would be necessary, extension of a new storm drain 129 DRAFT 26 pipe may require temporary or partial road closures. The nature and duration of those road closures would be subject to review by the County Public Works Department for compliance with applicable transportation regulations and require issuance of an encroachment permit. It should also be noted that the project was referred to the Contra Costa County Fire Protection District requesting comments. In a returned letter dated November 15, 2021, the Fire Protection District is requiring the applicant submit construction plans for review. All construction plans will be subject to the review of the Contra Costa County Fire Protection District for consistency with applicable Fire Code that is in effect at the time when the application for a building permit is submitted. Therefore, the routing review of construction plans will ensure that final construction plans will not result in a condition with inadequate emergency vehicle access. Accordingly, the project would have a less than significant impact on emergency response and emergency evacuation plans. g) Less Than Significant Impact: The project site is characterized as “urban unzoned” on the California Department of Forestry and Fire Protection’s Fire Hazard Severity Zone Map for local responsibility areas and thus, would not be considered to have a high hazard risk due to wildfires. The nearest High Fire Zone in Local Responsibility Area is over 2,000 feet north of the project site while the nearest High Fire Zone in State Responsibility Area is over 2 miles west. The project site is in a developed area within the service area of the Contra Costa County Fire Protection District (CCCFPD). Development projects are generally referred to the Fire District for review and comment to ensure that the proposal does not conflict with applicable fire codes. There was no indication from the CCCFPD review of the project that the proposed development poses a significant fire risk. Based on their review, the project proponent will be required to provide construction plans to the fire district for review and approval. The plans shall meet the 2022 California Building Code, 2022 California Residential Code and the applicable California Fire Code. Therefore, there is a less than significant impact of indirect risk of exposing people to loss, injury, or death involving wildland fire.

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 10. HYDROLOGY AND WATER QUALITY – Would the 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 project may impede sustainable groundwater management of the basin? c) Substantially alter the existing drainage pattern of 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? 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? SUMMARY: a) Less Than Significant Impact: The proposed development is residential in nature, and will not consist of any manufacturing, processing, industrial, or other commercial activities which would generate by-products or waste that would pose a significant risk for impacting water quality or waste discharge requirements within the County. The project site is located within the service of the MT. View Sanitary District service area and will have access to public sewage disposal services. A Stormwater Control Plan (SWCP) is required for applications that will create and/or redevelop impervious surface area exceeding 10,000 square feet (5,000 square feet for projects that include parking lots, restaurants, automotive service facilities and gas stations), 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 131 DRAFT 28 (NPDES) Permit. The proposed development is residential in nature, and will not consist of any manufacturing, processing, industrial, or other commercial activities which would generate by-products or waste that would pose a significant risk for impacting water quality or waste discharge requirements within the County. The project includes approximately 23,790 square feet of impervious surface (including the building and parking area), which is above the threshold for requiring submittal of a SWCP. The applicant submitted a preliminary Stormwater Control Plan (SWCP) for the proposed stormwater management facilities and controls as required by the County’s Stormwater Management and Discharge Control Ordinance. The SWCP submitted by the applicant has been deemed “preliminarily complete” by the County’s Public Works Department for the purposes of this phase of project review. Subsequent revisions and a final SWCP will be required as the project proceeds through the design and construction process. The project is not expected to violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality because the applicant shall be required to 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 II). Compliance shall include developing long-term best management practices (BMPs) for the reduction or elimination of stormwater pollutants. The project design shall incorporate, wherever feasible, long-term BMPs in accordance with the Contra Costa Clean Water Program for the site's stormwater drainage. b) Less Than Significant Impact: The project site is within the Contra Costa Water District (CCWD) service area. Since the project proposes to utilize a public water supply, no groundwater wells would be required. Pursuant to a letter from CCWD, the proposed development will require a fire service, a domestic service and an irrigation service for the landscaping. CCWD recommended that the applicant submit plans to the water district for review and approval. The project also plans to install up to four bioretention areas that would help facilitate groundwater recharge and help offset the increased impervious surface area on the project site. Therefore, there is less than significant potential for the project to substantially decrease groundwater supplies, interfere with groundwater recharge, or impede sustainable groundwater management of the basin. c) i, ii, iii Less Than Significant Impact: 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. A preliminary stormwater control plan was prepared by CALICHI Design Group which indicated that the storm drain improvements for this development would direct drainage to the frontage of Windhover Way. The applicant will construct retaining walls along the east and south property lines to eliminate 132 DRAFT 29 the current surface discharge of water to adjacent properties. The Contra Costa County Public Works Department has reviewed the drainage pattern at 98 Windhover Way and found no evidence that the property currently drains onto the vacant parcel at APN 380-220-066. The County elevation date contours imply that stormwater should natural drain southeast from 98 Winhover Way, avoiding the proposed project parcel. Additionally, the site proposed drainage upgrades to prevent any off-site drainage. The property slopes from the northwest corner to the southeast corner, away and considerably below street grade. The applicant proposes to install a bioretention facility onsite which discharges to an existing 18” storm drain in Windhover Way, effectively diverting the onsite flows. The applicant has requested an exception to Division 914 of the County Ordinance per section 92- 6.002 of the County Ordinance Code. Further, analysis of the project by the Contra Costa County Public Works Department determined that the applicant shall be permitted an exception from the collect and convey requirements of the County Ordinance Code and will be allowed to discharge to an existing storm drain provided that the applicant submit a drainage report to verify the adequacy of the downstream drainage system. The applicant will be required to submit a report verifying the adequacy of the stormwater facility or natural watercourse to which the stormwater shall be directed (and to ensure that the system is adequate). d) No Impact: Seiche, tsunami, and mudflow events are generally associated with large bodies or large flows of water. The project site is not located within a 100-year or 500-year flood plain as designated on the Federal Emergency Management Agency Flood Insurance Rate Map. According to the Safety Element of the County General Plan, the project site is not located in a hazard zone for mudflows. A seiche is a water wave in a standing body of water such as a large lake or reservoir that is caused by an earthquake, a major landslide, or strong winds. This hazard does not exist within the Martinez area as there are no large lakes or reservoirs in the area. As such, there would be no risk of pollutants being released from the site due to inundation through flooding, tsunamis, mudflows, or seiche, therefore, there would be no impact in this regard. e) Less Than Significant Impact: The project is not expected to violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality because the applicant shall be required to 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 II). Compliance shall include developing long-term best management practices (BMPs) for the reduction or elimination of stormwater pollutants. The project design shall incorporate, wherever feasible, long term BMPs in accordance with the Contra Costa Clean Water Program for the site's stormwater drainage. Therefore, the project would have a less than significant impact on the implementation of an adopted water quality control plan or sustainable groundwater management plan.

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 11. LAND USE AND PLANNING – 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? SUMMARY: a) No Impact: The subject property is currently vacant lot within a developed, urban area of the Martinez area in unincorporated Contra Costa County. Existing land uses in the vicinity primary consists of single-family residential development and related uses such as churches, schools, convenience stores, apartment buildings and townhouses. The project site is approximately 0.75 acres in area and is not large enough to constitute an independent established “community” within its boundaries. Furthermore, the proposed project does not consist of a new roadway, wall structure, or other improvements that would physically divide, or impede or disrupt the manner in which people enter and exit the Martinez area and the Windhover/Pacheco area in general. Due to the mixed-use zoning of the project vicinity, the proposed development would not divide an established community. b) Less Than Significant Impact: The applicant is requesting approval of a of a Development Plan to construct an approximately 22,247-square-foot in size, 24-unit apartment building, construct a covered carport for 16 parking spaces, and to install of associated improvements (e.g., pavement, utilities, stormwater conveyance) on a vacant property. The project includes a Tree Permit for the removal of four code protected trees within the dripline of three code protected trees. The project includes two units for low-income households and one unit for very low- income households and a request for a Density Bonus of two units for a total of 24 units. Land Use Element The project site is located within the Multiple-Family Residential High Density (MH) General Plan Land Use designation. Generally speaking, the intent of the MH designation is to allow for 134 DRAFT 31 residential uses such as apartments, condominiums, town houses and auxiliary uses such as churches. The proposed project would construct a 24-unit apartment complex on a parcel intended for High Density residential uses. The proposed apartment development will be residential in nature, and as a result will be compatible with other residential uses that surround the site. Within this designation, the General Plan allows for 22.0 to 29.9 multiple-family units per net acre. Thus, as proposed the multi-family project is consistent with the Contra Costa County General Plan development guidelines for the MH land use designation. General Plan Policies for the Vine Hill/Pacheco Boulevard Area The project site is located within the Vine Hill/Pacheco Boulevard area. As such, the following general plan policies for this area are applicable to the project and the project is consistent with these policies. • Policy 3-105: The scenic assets and unstable slopes of the Vine Hill Ridge are to be protected for open space/agricultural use. The proposed project is not located on or near Vine Hill Ridge. Therefore, the project will not impact the open space/agricultural use of that area. • Policy 3-106: The residential neighborhood east of I-680 shall be buffered from the industrial/landfill-related uses. The project parcel is located west of I-680, therefore this policy does not apply to the project. • Policy 3-107: Approximately 40 acres of land south of the Burlington Northern Santa Fe tracks, between Morello and Pacheco, is designated Agricultural Lands, to encourage the continued operation of the Viano family vineyards and winery. The project parcel is not located within the land designated in the policy. The project parcel is over 1,500 feet northeast of the Viano family vineyards and winery. Therefore, the project will not conflict with this policy. Housing Element A component of preparing the County’s Housing Element for the General Plan is the identification of vacant and underutilized suits 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). In order to assess whether this residential development application is subject to requirements of California Government Code section 65863, staff reviewed the site inventory for the adopted 2014 Housing Element and determined that Assessor’s Parcel Number 380-220-066 is not among the parcels listed in the inventory of residential sites which were relied upon to meet the 135 DRAFT 32 County’s share of regional housing needs. Nevertheless, the project includes a total of 24 residential units. The project includes one-bedroom and two-bedroom units. These unit types will increase housing opportunities for different size households for different income categories. As previously stated, this project maximizes the housing density and development of the site and includes a density bonus of nine percent above the base unit density for the site. Therefore, the project will contribute towards the regional housing need for the County and provide needed housing units for the region. Zoning The subject property is within the M-29 Multiple Family Residential (M-29) Zoning district. County Code 84-26.402 – Uses – Permitted (3) states that Multiple family buildings, but not including motels or hotels, is permitted use. Therefore, the proposed project is a permitted use within the M-29 Zoning. With the included variances and concessions pursuant to Government Code Section 65915(e), the application is consistent with the districts’ development standards and the County Zoning Ordinance. The district’s zoning development standards dictate allowable development in the area. The project would require two variances from these standards, building height and reduced driveway aisle width and would utilize the Density Bonus Request to request a concession to reduce the open space requirement and a reduction for parking stall size, parking setback and total number of covered parking spaces. The variance request for increased building height and parking aisle width would be consistent with the intent of the zoning district and are necessary given the project site’s constraints. The variance for building height is a result of the necessary lot padding that is required for drainage to be directed to Windhover Way as the lot is lower by almost 6 feet at the rear of the property. The added fill raises the height of the building from 34’ to 38’-6”. The reduced parking isle widths allows for the project allow the project to have more parking spaces and an aisle for vehicles to navigate. The reduction in parking aisle space allows for more maneuverability and to accommodate additional parking spaces. With the project proposing to meet the minimum landscape coverage, the driveway aisle space had to be reduced to accommodate this feature. With just a small reduction in the driveway aisle width, the project can provide more parking spaces and landscape area. The project requests the following concessions, reduction in development standards, and exception: • A density bonus concession to reduce the Open Space requirement from 25% to 20.5%; • A reduction in development standards pursuant to Government Code 65915(p) for parking ratios; • A reduction in development standards pursuant to Government Code 65915(e) for reduced parking stall size, parking setbacks, and total number of covered parking spaces; • An exception to Division 914, Collect and Convey requirements. 136 DRAFT 33 The project is subject to Chapter 822-4, the Inclusionary Housing Ordinance, and the applicant is required to constrict 3.3 inclusionary units. The applicant has submitted an Inclusionary Housing Plan, which proposes to construct and rent three inclusionary units. Two units will be available to “lower-income households,” and one will be available to a “very low-income household.” Although the project consists of requests for variances to allow for an increased maximum height and driveway aisle width, reduction in development standards to allow for reduced parking stall size, parking setbacks and total number of covered parking spaces, concessions to reduce the Open Space requirement, and an exception to the collect and convey drainage requirements the project substantially conforms to the design guidelines and General Plan Policies for the Martinez area as well as other General Plan policies and goals for unincorporated Contra Costa County. Therefore, the project has a less than significant potential for conflicting with any applicable land use, policy, General Plan, Specific Plan, or zoning ordinance adopted for the purpose of avoiding or mitigating an environmental effect.

MINERAL RESOURCES – Would the project: a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? b) Result in the loss of availability of a locally- important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? SUMMARY: a-b) No Impact: Pursuant to Figure 8-4 (Mineral Resource Areas) of the County General Plan Conservation Element, the project site is not located within any area of the County identified as a significant mineral resource area. No known mineral resources have been identified in the project vicinity, and there is no reason to believe that they exist at the project site. Therefore, the project would not result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state and would not impact any mineral resource recovery site.

NOISE – Would the project: a) 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? b) Generation of excessive groundborne vibration or groundborne noise levels? c) 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? SUMMARY: a) Less Than Significant Impact With Mitigation Incorporated: The subject property fronts Windhover Way. The project site is within an area of Martinez that is generally used for mixed use including residential, commercial and light industrial. Figure 11-5C of the Noise Element of the Contra Costa County General Plan (2005-2020, identifies that the subject property is within an area of the County where 2005 DNL and CNEL Noise levels range above 60 decibels (dB). Although Contra Costa County’s threshold for residential uses is a DNL of 60dB as shown on Figure 11-6 (Land Use Compatibility for Community Noise Environments) of the County General Plan’s Noise Element, the County requires new multiple-family residential projects to have an interior standard of 45dBA DNL or less. To evaluate the noise levels of the proposed project, a noise study was prepared by Michael Thill of Illingworth & Rodkin, Inc. A noise monitoring survey was conducted to quantify the existing noise environment at the site between Wednesday, April 27, 2022 and Friday, April 29, 2022. The noise monitoring survey included two long-term noise measurements (LT-1 and LT-2) and three short-term noise measurements (ST-1, ST-2, and ST-3), as showing in Figure 1. All noise measurements were conducted with Larson Davis Laboratories Model LxT1 Sound Level Meters fitted with ½-inch pre-polarized condenser microphones and windscreens. The meters were calibrated with a Larson Davis Model CAL200 precision acoustic calibrator prior to and following the measurement survey. The internal clocks of the sound level meters were synchronized to ensure 138 DRAFT 35 both identical sound level response and simultaneous operation. As shown in Figure 1 below, noise level measurements were taken in five areas within the subject property to determine the difference in noise levels. The surveys were conducted at elevated positions (e.g., 12 feet above the existing grade) to simulate noise exposure levels at the ground floor and second floors of the proposed apartment building. According to the study, traffic along Pacheco Boulevard was the predominant noise source at these locations. Table 3 summarizes the noise measurement results. The future noise environment at the project site will continue to result primarily from vehicle traffic along Pacheco Boulevard. An increase in traffic volumes along Pacheco Boulevard would correlate to an increase in noise levels at the project site. The Martinez General Plan Update forecasts a traffic noise level increase of 1 dBA Ldn along the adjacent segment of Pacheco Boulevard by the year 2040, with the future Ldn projected to reach 71 dBA at 75 feet from the roadway centerline. 139 DRAFT 36 Common outdoor us areas are proposed along the south and east boundaries of the site. Existing noise levels measured in these areas ranged from 55 to 59 dBA Ldn. By 2040, the unmitigated noise level would be expected to increase by 1 dBA Ldn and would range from 56 to 60 dBA Ldn. The project also proposes the construction of a 6-foot masonry wall along the south boundary of the site that would provide additional noise reduction. Therefore, future exterior noise levels would be less than 60 dBA Ldn and within the “normally acceptable” noise and land use compatibility range identified for residential land uses. Potential Impact: As shown on Figure 11-5 O of the Noise Element, the subject property is within an area of the County that is identified as having nose levels range above 60 decibels. The introduction of a new residential apartment building could introduce new noise sources including temporary noise from construction activities. There may be periods of time where there would be loud noise generated from the construction equipment, vehicles, and tools that would impact nearby residences and businesses. Additionally, outdoor-to-indoor noise may also be present due to the location of the project in close proximity to residences and Pacheco boulevard. Thus, the following mitigation measures shall be implemented. Mitigation Measure Noise 1: All windows and doors shall have the minimum ratings STC 26 and mechanical ventilation installed for the building. Mitigation Measure Noise 2: The following construction restrictions shall be implemented during project construction and shall be included on all construction plans. Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, whichever occurs first, the applicant shall provide evidence that the construction restrictions and requirements are included on the face of the construction plans. 1. The applicant shall make a good faith effort to minimize project-related disruptions to adjacent properties, and to uses on the site. This shall be communicated to all project-related contractors. The applicant shall notify neighbors within 300 feet of the subject property at least one week in advance of demolition, grading, and construction activities. 2. The project site shall be maintained in an orderly fashion at all times. All random debris and trash shall be disposed of in a timely manner. The project site must maintain and keep dust down by watering the site by use of a water truck, water hose, street sweeping and other dust control and maintenance measures. 3. A publicly visible sign shall be posted on the property with the telephone number and person to contact regarding construction-related complaints. This person shall respond and take corrective action within 24 hours. The CDD phone number to call in complaints shall also be visible to ensure compliance with applicable regulations. 4. The applicant shall require their contractors and subcontractors to fit all internal combustion engines with mufflers which are in good condition and shall locate stationary noise- generating equipment such as air compressors as far away from existing residences as possible. 5. The construction contractor shall ensure that unnecessary idling of internal combustion engines (i.e., idling in excess of 5 minutes) is prohibited. 140 DRAFT 37 6. The construction contractor shall utilize “quiet” models of air compressors and other stationary noise sources where technology exists. 7. 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. 8. Large trucks and heavy equipment are subject to the same restrictions that are imposed on construction activities, except the hours are limited to 9:00 am to 4:00 pm. This condition applies to all heavy construction equipment that vibrates. 9. Unless specifically approved otherwise via prior authorization from the Zoning Administrator, all construction activities shall be limited to the hours of 8:00 A.M. to 5:00 P.M., Monday through Friday, and are prohibited on State and Federal holidays on the calendar dates that these holidays are observed by the State or Federal government as listed below: New Year’s Day (State and Federal) Birthday of Martin Luther King, Jr. (State and Federal) Washington’s Birthday (Federal) Lincoln’s Birthday (State) President’s Day (State) Cesar Chavez Day (State) Memorial Day (State and Federal) Juneteenth National Independence Holiday (Federal) Independence Day (State and Federal) Labor Day (State and Federal) Columbus Day (Federal) Veterans Day (State and Federal) Thanksgiving Day (State and Federal) Day after Thanksgiving (State) Christmas Day (State and Federal) For specific details on the actual day the State and Federal holidays occur, please visit the following websites: Federal Holidays: Federal Holidays (opm.gov) California Holidays: https://www.calhr.ca.gov/employees/pages/state-holidays.aspx Complying with Noise 1 and Noise 2 will reduce interior noise levels to a level below the County’s interior standard of 45 dBA DNL and will reduce the amount of construction generated noise during project construction stages. By incorporating mitigation measures Noise 1 and Noise 2, the project shall have a less than significant impact on temporary or permanent increases in ambient noise levels in the vicinity of the project site, and the project will substantially comply with the Noise Element of the County’s General Plan. b) Less Than Significant Impact With Mitigation Incorporated: The proposed project for a 24-unit is a type of use that will not consist of any manufacturing, processing, or other activities that would typically result in excessive groundborne vibrations or groundborne noise would be 141 DRAFT 38 temporary in nature and would be limited to the restricted construction hours as typically conditioned for development permits approved by the County. These groundborne vibrations would be temporary in duration, however, nearby residences, business, and/or schools may be affected. Nevertheless, implementation of mitigation measure Noise 2 will reduce potential project impacts (that would result in the generation of groundborne vibration or noise to less than significant levels. c) No Impact: The project site is not located within two miles of a public airport or private airstrip, nor is it located within an area covered by the County’s Airport Land Use Compatibility Plan. The nearest airport facility is the Buchanan Field, approximately 2.3 miles southeast of the project site. Thus, the proposed project would not expose people to excessive noise levels from either Buchanan Field or a private airstrip and there is no impact.

POPULATION AND HOUSING – Would the project: a) Induce substantial unplanned population growth in an area, either directly (e.g., by proposing new homes and businesses) or indirectly (e.g., through extension of roads or other infrastructure)? b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? SUMMARY: a) Less Than Significant Impact: The project includes the construction of a three-story apartment building that proposes 24-units of residential (apartments) living spaces. Based on the United States Census Burau’s estimate of 2.48 persons per household (between 2017-2021) for Martinez, the project would potentially increase the population by an estimated 60 people. Since this project would result in a relatively small change in the population (per the United States Census Bureau date July 1, 2022, Martinez has an estimated population of 36,447), which means that the project would result in an approximately 0.16% percent increase in population for the area. This population increase would not require the extension of roads or other infrastructure. Therefore, the project would be less than significant. 142 DRAFT 39 b) No Impact: The proposed residential development will be constructed on a vacant lot that has been previously zoned for multi-family residential development. There is no need to alter or remove any of the surrounding residential units in order to establish the proposed development. Thus, the construction and establishment of the proposed 24-unit apartment complex would not displace any person, nor necessitate the construction of replacement housing elsewhere.

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 15. PUBLIC SERVICES – 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) Parks? e) Other public facilities? SUMMARY: a) Less Than Significant Impact: Fire protection and emergency medical response services for the project vicinity are provided by the Contra Costa County Fire Protection District. The project site is located within a 2.3 mile drive from Contra Costa County Fire Station 14, 2.7 mile drive from Contra Costa County Fire Station 9 and 3.3 mile drive from Contra Costa County Fire Station 13. The project is required to comply with the applicable provisions of the California Fire Code, the California Residential Code, and the Contra Costa County Ordinances that pertain to emergency access, fire suppression systems, and fire detection/warning systems. The proposed project has been reviewed by the Contra Costa County Fire Protection District. In a comment letter dated November 15, 2021, the fire district reviewed the project and did not indicate that a new fire protection facility would be needed as a result of the project. When it comes time to submit for building permits for the proposed project, the construction drawings would have to be reviewed and approved by the Contra Costa County Fire Protection District. As a result, the project’s potential impacts on fire protection would be less than significant. b) Less Than Significant Impact: Police protection and patrol services in the unincorporated Martinez area and the project vicinity are provided by the Contra Costa County Sheriff’s office. The Public Facilities/Services Element of the County General Plan requires 155 square feet of station area per 1,000 population in unincorporated Contra Costa County. As discussed earlier 143 DRAFT 40 in this study, the proposed project will create 24 residential (apartment units) which could potentially increase the population by an estimated 60 people (as discussed in the Population and Housing Section above.) This minimal population increase would not impact the County’s ability to maintain a Sheriff facility standard of 155 square feet of station area and support facilities per 1,000 members of the population. Thus, the project would not result in the need for new or expanded police protection facilities or services in the County. c) Less Than Significant Impact: The project site is located within the jurisdiction of the Martinez Unified School District and would induce a student increase to their classroom numbers. The project was referred to the Martinez Unified School District for comments. At the time of the completion of this study, no indication was received from the school district that expansion of existing school facilities would be necessary. However, to address student growth in school districts as a result of residential developments in the County, a per-square-foot school fee amount is determined by the school district. Prior to issuing building permits, the County Building Inspection Division collects the school fees on behalf of the respective school district as part of the overall building permit fees or requires a receipt showing payment of the applicable fee to the school district. Payment of the development fees pursuant to State regulations for school services would reduce impacts to neighborhood schools to less than significant levels. d) Less Than Significant Impact: The policy for Parks and Recreation in the Growth Management element of the County General Plan indicates that a standard of 3 acres of neighborhood parks per 1,000 persons should be maintained within the County. As stated previously, the project would not cause a significant population increase in the Martinez community. The applicant has proposed to landscape 20% of the project site as an outdoor area for use of future residents. While the project as proposed will not result in a significant increase in the County population, all residential projects are required to pay a Park Dedication and Park Impact fees which are adopted by the County Board of Supervisors to the County, which will be used to acquire park land and develop parks and recreation facilities to serve new residential development in the unincorporated County. Therefore, as the applicant has elected to pay an in-lieu fee instead of constructing new park areas in order to comply with the County Park Dedication Ordinance, there is no potential for the proposed project resulting in a substantial adverse environmental impact as a result of the construction of new or expanded parks. e) Less Than Significant Impact: During staff’s initial review of the proposed development and prior to deeming the project complete, project-specific comments were solicited from various local agencies and other interested parties in order to alert County staff and the applicant to any additional permitting, improvements, etc., that may be required as part of the project. Among the groups solicited for this project were the Contra Costa County Water District and MT. View Sanitary District. No indication of a need for new or expanded facilities was provided in the comments. The Contra Costa Library operates 28 facilities in Contra Costa County, including the Martine – Contra Costa County Library, located approximately 2.3 miles west of the project site. The Contra Costa Library system is primarily funded by local property taxes, with additional revenue from intergovernmental sources. A portion of the property taxes on the project site 144 DRAFT 41 would go to the Contra Costa Library system. Accordingly, the impact of the use of the public libraries by people living in the 60 residential (apartment) units would be less than significant. Contra Costa County Health Services District (CCCHSD) operates a regional medical center (hospital) and 10 health centers and clinics in the County. CCCHSD is primarily funded by federal and state funding programs, with additional revenue from local taxes. Since significant impacts to public facilities, such as hospitals are usually caused by substantial increases in population, the potential impact of the use of public health facilities by people living in the 60 residential (apartment) units would be less than significant.

RECREATION a) Would the project 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) Does the project include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment? SUMMARY: a) Less Than Significant Impact: The proposed development will induce a small population increase in the area, and as a result, it is anticipated that the use of neighborhood and regional parks in the area will also increase. Pursuant to the Growth Management Element of the County General Plan, the standard is to have a minimum of 3 acres of neighborhood parks for every 1,000 members of the population. The project includes the construction of a new 24-unit apartment complex that will increase the population by approximately 60 persons. This potential increase in population would not be significant enough to warrant the need for a new park, or substantially accelerate the deterioration of any existing parks or other recreational facilities. Additionally, the applicant will be required to pay Park dedication in-lieu fees as part of the project. Therefore, the proposed project would not substantially deteriorate existing park facilities. 145 DRAFT 42 b) Less Than Significant Impact: As previously stated, the potential increase in population would not be significant enough to warrant the need to construct or expand recreational facilities. Additionally, the applicant will be required to pay the County mandated park impact fee for each apartment unit. Park fees are collected to fund the acquisition and development of parks in Contra Costa County to serve unincorporated County residents.

TRANSPORTATION – Would the project: a) Conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities? b) Conflict or be inconsistent with CEQA Guidelines Section 15064.3(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? SUMMARY: a) Less Than Significant Impact: The subject property fronts Windhover Way. Windhover Way is 35 feet wide with two 10.5-foot travel lanes and parallel parking permitted on both sides. It has a prima facie speed limit of 25 mph. Windhover Way intersects with Pacheco Boulevard approximately 160 feet south of the proposed location for the project driveway. Pacheco Boulevard is classified as a Route of Significance and is oriented in the east-west direction. It has one travel lane and a bike lane in each direction together with a two-way left-turn lane. The posted speed limit is 45 mph. Parking is permitted on both sides where there is sufficient width. Policy 4-c of the Growth Management Element of the General Plan, and Chapter 82-32 (Transportation Demand Management) require a traffic impact analysis of any project that is estimated to generate 100 or more AM or PM peak-hour trips. In order to evaluate the project, a “Transportation Impact Analysis for the Apartments Residential Development Project,” study was prepared by W-Trans and received by the County on September 7, 2022. The anticipated trip generation for the proposed project was estimated using standard rates published by the Institute of Transportation Engineers (ITE) in Trip Generation Manual, 11th Edition, 2021 for “Multifamily Housing (Low-Rise)” (ITE LU #220). The site is currently undeveloped and therefore not generating any trips. For a conservative analysis, trip reductions resulting from 146 DRAFT 43 nearby transportation options were not applied. Further reductions attributable to internal capture, pass-by or any other trip reductions are not applicable and therefore have also not been applied. The expected trip generation potential for the proposed project is indicated in Table 1 below. The proposed project is expected to generate an average of 162 trips per day, including 10 trips during the a.m. peak hour and 12 during the p.m. peak hour; these new trips represent the increase in traffic associated with the project. Chapter 82-32 of the County Code requires the preparation of a “Transportation Demand Management” (TDM) program, for all residential projects with 13 or more dwelling units. The TDM Ordinance Guide encourages the use of creative and effective ways to reduce motor vehicle trips and their associated impacts created by new development projects. To minimize parking demand and reduce vehicle trips, the applicant may consider, but should not be limited to, reducing the number of parking spaces, providing bicycle and pedestrian infrastructure, providing transit passes, unbundling the price of parking from rent, providing emerging mobility options (e.g., electric scooters, bike share, etc.), and other strategies commonly used to minimize parking demand and automobile trips. Thus, W-Trans prepared a draft TDM program dated September 13, 2022 and received by the County on September 22, 2022 for the Apartment complex which recommends similar TDM measures. The draft TDM program concluded that the proposed pedestrian bicycle and transit facilities would be adequate to serve the project as proposed; the number of short and long term bicycle parking spaces proposed would be greater than the County’s requirement and that the implementation of the TDM program would reduce vehicle trips. Staff of the County’s Transportation Planning division further recommends that a final TDM Program and a TDM Coordinator be required as conditions of approval. Since the proposed project would generate less than 100 peak hour trips, a traffic impact analysis is not required in accordance with General Plan Policy 4-c. In addition, as recommended by County Transportation Planning staff, compliance with the County’s Electric Vehicle (EV) Ordinance and requiring a final TDM program and a TDM Coordinator as conditions of approval would ensure that the project results in a less than significant impact on programs, plans, ordinances or policies regarding transit, roadway, bicycle, and pedestrian facilities. b) Less Than Significant Impact: CEQA provides guidelines for analyzing transportation impacts relating to vehicle miles travelled (VMT) resulting from the project. The Governor’s Office of Planning and Research (OPR) established recommendations for identifying and mitigating transportation impacts within CEQA and published a final Technical Advisory in December of 2018 that advises lead agencies to conduct a screening process to “quickly identify when a project should be expected to cause a less-than-significant impact without conducting a detailed study.” As mentioned above, W-Trans prepared a “Vehicle Miles Traveled (VMT) Evaluation” 147 DRAFT 44 on behalf of the project applicant to identify whether the project would be expected to cause a significant impact and, thus, require a detailed VMT study. W-Trans identified the following project screening criteria as part of their assessment. Consideration was given to the project’s potential generation of Vehicle Miles Traveled (VMT). As a result of SB 743, the Board of Supervisors adopted a VMT policy on June 23, 2020, in their document Transportation Analysis Guidelines. Guidance provided in this document recommends the use of screening thresholds to identify when a proposed project is presumed to result in a less-than-significant impact without conducting a detailed study. According to the Contra Costa County Travel Demand Model estimates, the Countywide home- based average VMT per resident is 19.4 miles. Concurring with guidance provided by this document, a project located anywhere in the County which generates a VMT that is 15-percent or more below this value, or 16.5 miles per resident, should be expected to cause a less-than- significant VMT impact and would not require further VMT analysis. The project would be located within Traffic Analysis Zone (TAZ) 20034 of the Contra Costa Travel Demand Model which has a home-based VMT of 16.0 miles per resident. Because this per capita VMT rate of 16.0 is lower than the significance threshold of 16.5 miles, the project is presumed to have a less-than-significant VMT impact and does not require further VMT analysis. Further, adjacent TAZs west of I-680, including 20033 and 20038, also have a per capita VMT rate that is less than the significance threshold so are consistent with TAZ 20034. A summary of the VMT findings is provided in Table 4 below. As shown in the table above, the project will a lower VMT rate than the significance threshold. Per CEQA section 15064.3(b) – Determining the Significant of Transportation Impacts, a transportation project that does not exceed the significant threshold is considered to have a less than significant transportation impact. Therefore is determined to not be inconsistent with CEQA Guidelines Section 15064.2(b). c) Less Than Significant Impact: The subject property fronts Windhover Way, which is 35 feet wide with two 10.5-foot travel lanes and parallel parking permitted on both sides. It has a prima facie speed limit of 25 mph. As shown on Figure 5-2 (Roadway Network Plan) of the General Plan Transportation and Circulation Element, Windhover Way is not considered to be an existing or proposed arterial, expressway, or freeway. According to the project plans, the site will have access from a private driveway located on Windhover Way, approximately 160 feet north of Pacheco Boulevard. This will be the only access point to and from the proposed 148 DRAFT 45 project. The proposed apartment building will be setback approximately 100 feet from the roadway entrance, therefore, not creating any site obstructions or hazards in relation to the Windhover Way circulation. As part of the review process, the County referred the project out to the Contra Costa County Public Works Department for review. In a Staff Report dated December 19, 2022, the Public Works Department stated that there is no need to “further widening or frontage improvements are necessary with this development,” and provided a standard condition of approval that requires the applicant to adhere to Chapter 82-18, “Applicant shall provide sight distance at the intersection of the private driveway with Windover Way in accordance with Chapter 82-18 “Sight Obstructions at Intersections” of the County Ordinance Code. The applicant shall trim vegetation, as necessary, to provide sight distance at this intersection, and any new signage, landscaping, fencing, retaining walls, or other obstructions proposed at this intersection shall be setback to ensure that the sight line is clear of any obstructions.” No substantial changes to the existing transportation system are proposed with this application. Compliance with the Public Works conditions of approval will result in the project having a less than significant impact on the Windhover Way right-of-way and is not expected to substantially increase hazards due to geometric design features or incompatible uses. d) Less Than Significant Impact: The project was referred to the Contra Costa County Fire Protection District for agency comments. In a comment letter dated November 15, 2021, the Fire Protection District stated that the project shall comply with the applicable California Fire Code, the California Building Code, the California Residential Code and Local and County Ordinances and adopted standards. All construction plans will be subject to the applicable Fire Code that is in effect at the time when the application for a building permit is submitted. Additionally, the applicant will work with the Fire Protection District to submit construction plans for review and approval prior to building permit issuance. Therefore, the routine review of construction plans will ensure that the proposed project has no potential for adversely impacting existing emergency access to the subject property or other properties within the County.

TRIBAL CULTURAL RESOURCES – Would the project 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) 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)? b) 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? SUMMARY: a-b) Less than Significant Impact With Mitigation: As discussed in the Cultural Resources section 5of this study, there are no known existing structures located at the project site that are listed on the Contra Costa County’s Historic Resource Inventory, or the California’s Register of Historical Resources, or the National Register of Historic places, nor is there any building or structure that qualifies to be listed. The project site is vacant. In addition, the project was referred out to the California Historical Resources Information System (CHRIS) to which they responded in a letter dated November 22, 2021, stating that “the proposed project area has a low possibility of containing unrecorded archaeological sites.” Additionally, there is no evidence in the record at the time of completion of this study that indicates the presence of human remains at the project site. On May 23 and May 24, 2021, a Notice of Opportunity to Request Consultation for the proposed Apartment Building was sent to the Wilton Rancheria and the Confederated Villages of Lisjan Nation, two California Native American tribes that are traditionally and culturally affiliated with the geographic area. No requests for consultation or responses regarding tribal cultural resources have been received from California Native American tribes at the time of completion of this study. Potential Impact: As discussed previously in Section 5, subsurface construction activities have the potential to damage or destroy previously undiscovered historic and prehistoric resources. Therefore, the implementation of Mitigation Measure Cultural 1 and Mitigation Measure Geology 6 will ensure that project-related impacts to previously undiscovered and unknown cultural resources will be less than significant.

UTILITIES AND SERVICE SYSTEMS – Would the project: a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction of which could cause significant environmental effects? b) Have sufficient water supplies available to serve the project and reasonably foreseeable 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 management and reduction statutes and regulations related to solid waste? SUMMARY: a) Less Than Significant Impact: The project site is located in a developed, urbanized area of Unincorporated Martinez, which is served by existing water, sewer, storm drain, electric power, natural gas and telecommunications services. There is no indication from any utility service provider that the proposed residential complex would result in a need to relocate, expand, or construct new facilities in such a way as to cause significant environmental effects. Water: The new development is located within the service area of the Contra Costa Water District. Project plans have been sent to the Water District as part of the initial review process. In a letter dated November 18, 2021, the Water District provided comments stating that the new development will require a fire service, a domestic service and an irrigation service. The letter also requested that the applicant work with the Water District engineering services to request water service for the site. The Contra Costa Water District staff has reviewed the project application documents regarding the provision of new water service pursuant to their water service regulations and there has been no indication from the water company that the proposed project would exceed the capacity of the existing public water infrastructure. Wastewater treatment: The project is within the MT. View Sanitary District service area, which is the agency responsible for ensuring that applicable wastewater treatment requirements of the Regional Water Quality Control Board are met and maintained. The wastewater generated by 24 new apartment dwelling units would incrementally increase wastewater flows in the MT. View Sanitary District system. Project plans have been sent to MT. View Sanitary District as 151 DRAFT 48 part of the initial review process, and there is no indication that the proposed project would exceed their ability to provide sewer services with the currently available facilities. In a returned comment letter dated November 17, 2021, MT. View Sanitary District requested that the applicant submit sewer improvement plans to the District and that a sewer permit application shall be required to be obtained from the District. Therefore, there is no indication that the project would require expansion of the wastewater treatment system. Storm water drainage: As discussed in the Hydrology and Water Quality section above, the applicant has submitted a preliminary Storm Water Control Plan (SWCP) designed with project storm water controls including permeable AC pavements to be used in the parking stalls, landscaping and bioretention facilities. The project proposes to capture stormwater runoff from the site into a bioretention facility onsite which will discharge to an existing 18” storm drain in Windhover Way. The applicant also is requesting an exception to Division 914 of the County Ordinance. The storm water and drainage facilities were reviewed by the Contra Costa County Public Works department and in a Staff Report and Recommended Conditions of Approval dated December 19, 2022, Public Works stated that they are not averse to granting the exception. Additionally, they deemed the applicant submitted Preliminary Stormwater Control Plan dated February 22, preliminary complete. Conditions of approval from Public Works is required a final Stormwater Control Plan which will be submitted prior to the applicant obtaining a building permit. The Final Storm Water Control Plan (SWCP) will be accompanied by a Stormwater Control operation and Maintenance Plan and will be required to be in compliance with the County’s National Pollutant Discharge Elimination System and shall be consistent with the County’s Stormwater Management and Discharge Control Ordinance. Based on the incorporation of a SWCP to control the increased runoff, the review by the County agency responsible for enforcing drainage standards, and upon implementation of the conditions of approval from the Contra Costa County Public Works Department, the proposed project would have a less than significant adverse environmental impact on stormwater or wastewater treatment facilities. Electric/Natural Gas: The project is within the service territory of PG&E for electric and natural gas service. It is anticipated that the project will connect to underground electric and/or natural gas connections. There is no indication that the construction of new or expanded electric or natural gas services is required for the ongoing operation of the project. Temporary power for construction activities would also be provided by PG&E. The applicant will be required to apply for temporary power and follow the permitting process for connecting to the electrical grid. Telecommunication Services: Existing telephone, cellular, internet, and cable television are available within the project site’s vicinity. The project site would connect to these services provided by several different providers, and there is no indication that the 24 new residential units would result in the need for expanded services such as new or larger wireless facilities. By following the processes required to connect to existing water, wastewater treatment, storm water drainage, electric power, natural gas, or telecommunications facilities, the impacts of the project concerning these utilities and services would be less than significant. 152 DRAFT 49 b) Less Than Significant Impact: The project site is presently served by municipal water supplies from the Contra Costa Water District. According to County records, the project parcel is not located in an area with a Groundwater Act. As discussed in subsection-a above, the new development will be required to work with the Contra Costa Water District. The Water District staff has reviewed the project application documents regarding the provision of new water service pursuant to their water service regulations and there has been no indication from the water company that the existing public water infrastructure would have insufficient water supplies to serve the project, or that the project would have a significant impact on the public water infrastructure during dry, and multiple dry years. c) Less Than Significant Impact: As discussed in subsection-a above, the new development is within the MT. View Sanitary District, which is the agency responsible for ensuring that applicable wastewater treatment requirements of the Regional Water Quality Control Board are net and maintained. Project plans were sent to the MT. View Sanitary District as part of the initial review process, and there has been no indication from them that the proposed project would exceed their ability to provide sewer services with the currently available facilities. Nor is there any indication that the project would require expansion of the wastewater treatment system. In a comment letter dated November 17, 2021, the District is requiring the applicant to submit sewer improvement plans for review and approval and to submit a sewer permit for the final District approval. The Sanitary District would connect the dwelling units to its facilities after processing the residential sewer service application and collecting the applicable connection fees, completing a building plan review, and issuing a permit for sewer work. By following this process, the impacts related to the wastewater treatment requirements of the Regional Water Quality Control Board for the San Francisco Bay Region or the Mt. View Sanitary facilities would be less than significant. d) Less Than Significant Impact: The proposed project would generate construction solid waste and post-construction residential solid waste. Construction on the project site would be subject to the CalGreen Construction and Demolition Debris Recovery Program administered by the Department of Conservation and Development at the time of application for a building permit. The Debris Recovery Program requires that at least 65% of construction job site debris (by weight) for all new residential buildings requiring permits that would otherwise be sent to landfills be recycled, reused, or otherwise diverted to appropriate recycling facilities. Thus, although future construction of the apartment buildings would incrementally add to the construction waste, the impact of the project-related increase would be considered to be less than significant. The proposed project would be comprised of residential apartment units, which would generate the type of solid waste similar to that of other medium density residential uses in the vicinity. The apartment building will be required to comply with the County Ordinance which requires solid waste collection for all three waste streams (garbage, recycling and organics.) The project plans indicate that there will be a proposed trash enclosure located behind the frontage, near the front of the building. Regular solid wase removal for households in the Martinez area is provided by Republic Services, which also provides recycling and green waste removal services. Household waste is ultimately destined for the Keller Canyon Landfill, which has enough approximate capacity to continue accepting waste for the next 50 years. Household 153 DRAFT 50 waste from the 24-unit apartment project would incrementally add to the household waste headed to the landfill. However, the potential for the proposed project to exceed the capacity of the currently utilized landfill is minimal, and the impact of the project-related waste would be considered to be less than significant. e) Less Than Significant Impact: As mentioned above, construction at the project site would be subject to the CalGreen Construction and Demolition Debris Recovery Program administered by the Department of Conservation and Development. The Debris Recovery Program requires that at least 65% of construction job site debris (by weight) for most construction types, that would otherwise be sent to landfills, be recycled, reused, or otherwise diverted to appropriate recycling facilities. The proposed project is not expected to produce significant amounts of waste that would present a greater conflict with laws and regulations regarding solid waste than similar multiple and single-family residences in the vicinity. Furthermore, the owner, construction contractor, and future tenants would be subject to applicable federal, state, and local laws related to solid waste. Therefore, the potential for conflict with Federal, State, and local management and reduction statutes and regulations related to solid waste is less than significant.

WILDFIRE – If located in or near the 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? SUMMARY: a) Less Than Significant Impact: The site is not located in an area of State Responsibility Area according to the Contra Costa County’s State Responsibility Area Fire Hazard Severity Zones on the California Department of Forestry and Fire Protection’s Fire Hazard Severity Map. The project site is not located near any state responsibility lands classified as a Very High Fire Hazard Severity Zone. The nearest State Responsibility Area High or Very High Fire zone is located more than 2.5 miles to the west. The project is located in a Local Responsibility Area classified as Urban Unzoned. The project site is in a developed area within the service area of the Contra Costa County Fire Protection District (CCCFPD). The project was routed to the CCFPD, who did not indicate any concerns with an elevated risk of wildfires for the site. The project will be required to comply with current fire codes, including those pertaining to fire sprinklers in new buildings, and driveway and roadway access for firefighting apparatus, and would not require the installation or maintenance of additional infrastructure such as roads or fuel breaks that may exacerbate fire risk. Additionally, the applicant will be required to submit construction plans to the fire department for review and approval before any building permits will be issued to ensure compliance with the applicable fire and building codes. Therefore, the routine review of construction plans will ensure that final construction plans will not result in a condition with inadequate emergency vehicle access. b) Less Than Significant Impact: The project site is not located in or near a state responsibility areas or lands classified as very high fire hazard severity zones. Therefore, the risk of exposing project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire is less than significant. The project is located on a lot with a slight slope, however, surrounding parcels are relatively flat and within an urbanized area and, thus, would not expose people or structures to significant risks as a result of post-fire slope instability or runoff. Development will be subject to review and approval by the Contra Costa County Fire 155 DRAFT 52 Protection District. It is expected that compliance with the California Fire Code, California Building Code, California Residential Code and Local and County Ordinances, will keep the project-related risks associated with wildfires at less than significant levels. c) Less Than Significant Impact: The project site is not located in or near a state responsibility areas or lands classified as very high fire hazard severity zones. The project does not require any road widening or frontage improvements. The project was reviewed by the CCCFPD and does not require the installation of emergency roads, fuel breaks, emergency water sources that may exacerbate fire risk. Additionally, Chapter 96-10 of the County Ordinance Code requires all new utility distribution services to be installed underground, thereby reducing fire risk in the area. Thus, project-related risks (regarding installation or maintenance of associated infrastructure associated with fire risks) shall have a less than significant impact on the environment. d) Less Than Significant Impact: The project site is not located in or near a state responsibility areas or lands classified as very high fire hazard severity zones. The project site contains a slight slope but does not contain any hills or steep topography. Moreover, the surrounding area is relatively flat and is not near a major body of water that would be susceptible to flooding. Therefore, the risk of exposing people or structures to significant risks, including downslope or downstream landslides, as a result of runoff, post-fire slope instability, or drainage changes is less than significant.

MANDATORY FINDINGS OF SIGNIFICANCE a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory? b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects.) c) Does the project have environmental effects, which will cause substantial adverse effects on human beings, either directly or indirectly? SUMMARY: a) Less Than Significant Impact With Mitigation: Although the development of the proposed multi-family residential complex would be contained within the 32,820 square foot project site, due to the undeveloped nature of the project site, it has the potential for impacting the environment. As stated in this Initial Study, the project is located in an area that is vacant and surrounding by urbanized uses. There is no evidence in the record that the site or surrounding area contains substantial habitat for fish or a wildlife species or will reduce a rare or endangered plant or eliminate an important period in California history. The project was referred to numerous agencies who provided comments on the project stating that impacts would be minimal. However, due to the undeveloped nature of the project, there is a potential for impacting the environment in relation to undiscovered resources. The project would not substantially degrade the quality of the natural environment because the potentially significant impacts regarding aesthetics, cultural/tribal resources, air quality, noise, geology/soils as identified throughout this initial study, can be mitigated to less than significant levels. Where mitigation measures are enforced as proposed in this Initial Study, the measures will be conditions of approval of the proposed project and the applicant will be responsible for implementation of the measures. Therefore, the potential for substantial impacts to the environment or other resources related to the environment as a result of the proposed project is reduced to a less than significant level. b) Less Than Significant Impact With Mitigation Incorporated: The project site is located within the Urban Limit Line in an area that has been designated for multiple-family high-density residential development. The number of housing units in the Martinez area would increase by 157 DRAFT 54 24-units with the proposed project. The project site is the only vacant parcel located on Windhover Way and is one of a few vacant parcels within a two-mile radius. Staff is aware of one substantial development project in the immediate vicinity within the Martinez area that is under review. Staff is unaware of any substantial development projects in the nearby Martinez area that have recently been approved. The project under review is as follows: 1. (County File #CDDP22-03036) The project includes a Development Plan modification to allow for a 33-unit multi-family residential project in four buildings on two lots with 78 on- site parking spaces. The application also includes a Vesting Tentative Map to allow a 33-unit multi-family residential subdivision. The development would be located on APN 380-220- 044, 3845 Pacheco Blvd, Martinez, CA 94553. The project is currently deemed incomplete during the 30-day application review. This area of the County is readily serviced by the public services and utilities such as water, power, sanitary, and fire protection. The Community Development Division (CDD) generally solicits project specific comments from these agencies as part of the application review process, and design modifications are made based on the advice of each respective agency. The consulted agencies are the governing bodies with proficient knowledge of the needs of their existing infrastructure, and no indication of potential impacts or the need for new or expanded services was noted for the project proposal. Therefore, County CDD staff’s consultation with outside agencies for each project and with implementation of the proposed mitigation measures for this proposed project reduces the potential for significant cumulative environmental impacts related to new or expanded utilities to a less than significant level. The proposed project will have temporary impacts that would occur as a result of construction activities that would be mitigated at the project level. No long-term adverse impacts are anticipated to occur, and as such, the incremental effects of the project would not be considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects. With the implementation of the mitigations described in the sections above, the proposed project would not result in cumulatively considerable impacts on the environment. c) Less Than Significant Impact With Mitigation Incorporated: This Initial Study has disclosed potential impacts on human beings that would be less than significant with the implementation of mitigation measures. All identified mitigation measures will be included as conditions of approval for the proposed project, and the applicant will be responsible for implementation of the measures. As a result, there would not be any environmental effects that will cause substantial adverse effects on human beings, either directly or indirectly. 158 REFERENCES In the process of preparing the Initial Study Checklist and conduction of the evaluation, the cited references were consulted.

Onsite inspection and monitoring of construction vehicles, equipment, and project site. SECTION 5: CULTURAL RESOURCES Potentially Significant Impacts: Although there is no evidence that there is any specific cultural resources known in in the project area, there is nevertheless a potential for previously unknown 165 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 4 of 11 Building Inspection Division (BID) cultural resources to be uncovered during construction activities requiring excavation or earth movement. Mitigation Measure(s): CULTURAL-1: The following measures shall be implemented during project-related ground disturbance and shall be included on all construction plans. Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the applicant shall provide evidence that the measures and requirements listed below are included on the construction plans. If deposits of prehistoric or historical archaeological materials are encountered during ground disturbance activities, all work within 50 feet of the discovery shall be redirected. A qualified archaeologist certified by the Society for California Archaeology (SCA) and/or the Society of Professional Archaeology (SOPA), and the Native American Tribe that has requested consultation and/or demonstrated interest in the project shall be contacted to evaluate the significance of the finds and suggest appropriate mitigation(s) if deemed necessary. A. All construction personnel, including operators of equipment involved in grading, or trenching activities will be advised of the need to immediately stop work if they observe any indications of the presence of an unanticipated cultural resource discovery (e.g., wood, stone, foundations, and other structural remains; debris-filled wells or privies; deposits of wood, glass, ceramics). If deposits of prehistoric or historical archaeological materials are encountered during ground disturbance activities, all work within 50 feet of the discovery shall be redirected and a qualified archaeologist contacted to evaluate the finds and, if necessary, develop appropriate treatment measures in consultation with the County and other appropriate agencies. If the deposits are not eligible, avoidance is not necessary. If eligible, deposits will need to be avoided by impacts or such impacts must be mitigated. Upon completion of the archaeological assessment, a report should be prepared documenting the methods, results, and recommendations. The report should be submitted to the Northwest Information Center and appropriate Contra Costa County agencies. B. If human remains are encountered, work within 50 feet of the discovery shall be redirected and the County Coroner notified immediately. At the same time, an archaeologist shall be contacted to assess the situation. If the human remains are of a Native American origin, the Coroner must notify the Native American Heritage Commission within 24 hours of this identification. The Native American Heritage Commission will identify a Most Likely Descendant (MLD) to inspect the property and provide recommendations for the proper treatment of the remains and associated grave goods. 166 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 5 of 11 Building Inspection Division (BID) Upon completion of the assessment by an archaeologist, the archaeologist should prepare a report documenting the methods and results and provide recommendations for the treatment of the human remains and any associated cultural materials, as appropriate and in coordination with the recommendations of the MLD. The report should be submitted to the Northwest Information Center and appropriate Contra Costa agencies. Implementing Action: COA Timing of Verification: Upon discovery of archaeological materials or human remains Party Responsible for Verification: Project proponent, CDD staff, consulting Archaeologist Compliance Verification: Review of archaeologist’s report or other verification provided to CDD staff SECTION 7: GEOLOGY AND SOILS Potentially Significant Impacts: The consulting geotechnical engineer indicates potentially expansive and corrosive soils existing on the subject property which can be detrimental to concrete and buried metal such as those used for utilities or reinforcing steel. In addition, conditions in the field may vary from those expected based on field investigation, laboratory tests, and engineering analysis performed by the consulting engineer. Thus, it is critically important that adequate geotechnical review be provided. Additionally, ground disturbance during the project’s construction phase has the potential for disturbing previously unknown unique paleontological resources. In addition to the mitigation measures for Cultural Resources, the following mitigation measures will ensure that in the event unique paleontological resources are discovered, the proper actions are taken to reduce the adverse environmental impacts to unique paleontological resources to a less than significant level. Mitigation Measure(s): GEOLOGY-1: Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the project proponent shall submit a geotechnical report update with the geotechnical review fee in the amount of $3,000, referencing the proposed grading, drainage and foundation plans and providing specific criteria and standards for site grading, drainage and foundation design based on adequate subsurface data, laboratory testing of samples and engineering analysis. The scope of the geotechnical investigation shall address the following potential hazards: (i) expansive soils, (ii) corrosive soils, (iii) siting and design of any required bio-retention facilities and/or other measures that may be recommended to achieve compliance with the clean water requirements of the RWQCB, (iv) possible presence of existing undocumented fills and effective measures 167 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 6 of 11 Building Inspection Division (BID) to control/ mitigate the settlement hazard, (v) provide seismic parameters based on the adopted California Building Code at the time that a residential building permit is requested. GEOLOGY 2: Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the geotechnical report update required by Geology 1, above, shall be subject to review by the County’s peer review geologist, and review/approval of the CDD. Improvement, grading and building plans shall carry out the recommendations of the approved report. GEOLOGY 3: Following rough grading (but prior to commencement of foundation-related work) the project geotechnical engineer shall perform corrosion potential testing of the graded building pad to determine if special precautions shall be required to avoid damage to improvements that are in contact with the ground (concrete or steel). GEOLOGY 4: The geotechnical report required by Geology 1 routinely includes recommended geotechnical observation and testing services during construction. These services are essential to the success of the project. They allow the geotechnical engineer to (i) ensure geotechnical recommendations for the 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 BID approval), based on exposed conditions. The monitoring shall commence during clearing, and extend through grading, including testing services during placement of engineered fill, installation of recommended drainage facilities, and foundation related work. A hard 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 during grading, installation of drainage improvements. Similarly, a hard hold shall be placed on the final building inspection for the apartment building, pending submittal of a letter-report from the geotechnical engineer documenting the monitoring services associated with implementation of foundation-related geotechnical recommendations. The geotechnical monitoring shall include pier hole drilling/ foundation preparation work/ installation of drainage improvements (e.g. collection of roof gutter runoff in a closed conduit and conveying it to a suitable discharge point; and possibly installation of a subdrain system around the perimeter of the foundation to control moisture beneath the foundation). GEOLOGY 5: 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, unless additional grading is reviewed and specifically approved by the Building Inspection Division. 168 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 7 of 11 Building Inspection Division (BID) GEOLOGY 6: Should unique paleontological materials be uncovered during grading, trenching, or other on-site excavation(s), all earthwork within 30 yards of the materials shall be stopped until the Community Development Division (CDD) has been notified, and a qualified paleontologist contacted and retained to evaluate the significance of the find, and, if deemed necessary, suggest appropriate mitigation(s).

The introduction of a new residential apartment building could introduce new noise sources including temporary noise from construction activities. There may be periods of time where there would be loud noise generated from the construction equipment, vehicles, and tools that would impact nearby residences and businesses. Additionally, outdoor-to-indoor noise may also be present due to the location of the project in close proximity to residences and Pacheco boulevard. Mitigation Measure(s): NOISE-1: All windows and doors shall have the minimum ratings STC 26 and mechanical ventilation installed for the building. NOISE 2: The following construction restrictions shall be implemented during project construction and shall be included on all construction plans. Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, whichever occurs first, the applicant shall provide evidence that the construction restrictions and requirements are included on the face of the construction plans. 169 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 8 of 11 Building Inspection Division (BID) 1. The applicant shall make a good faith effort to minimize project-related disruptions to adjacent properties, and to uses on the site. This shall be communicated to all project- related contractors. The applicant shall notify neighbors within 300 feet of the subject property at least one week in advance of demolition, grading, and construction activities. 2. The project site shall be maintained in an orderly fashion at all times. All random debris and trash shall be disposed of in a timely manner. The project site must maintain and keep dust down by watering the site by use of a water truck, water hose, street sweeping and other dust control and maintenance measures. 3.

D. ADOPT the mitigated negative declaration (State Clearing House No. 2023070169) prepared for the project. E. ADOPT the mitigation monitoring program for the project. F. DIRECT the Department of Conservation and Development to file a CEQA Notice of Determination with the County Clerk. G. SPECIFY that the Department of Conservation and Development, located at 30 Muir Road, Martinez, California, is the custodian of the document and other material that constitutes the record of proceedings upon which the decision of the Board of Supervisors is based. H. APPROVE a variance to allow a building height of 38’-6” (where 30’ is the maximum allowed) and a driveway aisle width of 24.5’ (where 25’ is minimum required). 179 CPC – August 9, 2023 County File #CDDP21-03031 Page 3 of 20 I. APPROVE a density bonus to allow two additional units (for a total of 24 units), the requested concession to reduce the open space requirement, and the requested reduction in development standards related to parking stall size, parking setbacks, and number of covered parking spaces. J. APPROVE the Development Plan for the project, including the associated tree permit and requested exception from Title 9 offsite collect and convey requirements (CDDP21-03031). K. APPROVE the findings in support of the project. L. APPROVE the project conditions of approval. M. APPROVE the Windhover Terrace Apartments Project. III. BACKGROUND An application for the approval of a Development Plan, Variance and Tree Permit, which includes a request for a density bonus, concessions and reduction to development standards, for the construction of a new 24-unit apartment complex was submitted to the Department of Conservation and Development on October 12, 2021. The matter was initially heard by the County Zoning Administrator on January 23, 2023, during which the County Zoning Administrator accepted testimony and continued the Public Hearing to February 22, 2023, as an open public hearing. At the February 22, 2023, Public Hearing, testimony was accepted from the applicant and members of the public. After receiving testimony and considering the project analysis provided by County staff, the County Zoning Administrator approved the Development Plan with modifications and added conditions of approval. Staff received one letter appealing the Zoning Administrator’s decision from Joe Hise on February 27, 2023, which included a list of neighbors who signed the appeal letter. Staff’s analysis and response to the appeal letter is discussed in Section VII (Appeal of Zoning Administrator’s February 22, 2023 decision) of this Staff report. Since the Zoning Administrator’s decision, staff determined that it was appropriate to conduct additional environmental review of the project under the California Environmental Quality Act. In accordance with CEQA Guidelines, Section 15071 and Section 15072, a Mitigated Negative Declaration/Initial Study (MND) was prepared and published for the project. The 20-day public review period for the MND started on July 11, 2023, and ended on July 31, 2023. Seven public comments were received from Steve Schmedinghoff, Jesse Ma, Gayle Ansell, Kevin Mulcahy, Charlene Crisafulli-Mulcahy, Contra Costa Water District and the Contra Costa County Fire Protection District during the public review period for the MND. Staff’s analysis and response to the comments received during the public review 180 CPC – August 9, 2023 County File #CDDP21-03031 Page 4 of 20 period of the MND is discussed in Section VI (CEQA Public Comments). IV. SITE/AREA DESCRIPTION Site Description: The subject lot is approximately 0.77-acres in size (approximately 32,820 square feet) and is a rectangular shaped parcel that includes a 52’ x 70’ strip extending to the west connecting the parcel to Windhover Way. The parcel is located on the east side of Windhover Way, approximately 125 feet north of the Pacheco Boulevard and Windhover Way intersection in the in the Pacheco/Vine Hill area. The parcel is vacant and is largely covered with grass and dirt and has eight trees located around the perimeter of the parcel. There is existing curb, sidewalk, streetlights, and underground utilities along the frontage of Windhover Way. Public Works has reviewed the submittal and has indicated that the applicant will not be required to perform further widening or frontage improvements. The general topographic slope of the parcel trends downward from west to east. The elevation starts at 40 feet above mean sea level at Windhover Way and slopes down to 31 feet above mean sea level at the rear of the property. The site currently has access off of Windhover Way which will continue to remain as the access point. The site contains seven trees consisting of London Plane, Carolina Cherry Laurel, California Black Walnut, Glossy Privet and Olive tree. There are two off-site trees located in close proximity to the project parcel that will not be removed by the project including a Siberian elm at the project frontage and a Coast Redwood towards the southeast corner. Surrounding Land Uses: This area along Windhover Way is exclusively occupied by residential development. The adjacent parcels to the north and south host single family residences. To the east of the site is a 13-unit townhouse development. The two properties to the west both host duplexes. Approximately 316 feet northeast of the subject property is a 12-unit apartment complex. Beyond the immediate neighborhood, along Pacheco Boulevard there are a variety of residential, commercial, and retail uses including multi- family housing, restaurants, schools, storage locations, gas stations, auto repair shops, and other retail services. Parcels within the City of Martinez jurisdiction are located approximately 1,100 feet to the east of the subject parcel. V. PROJECT DESCRIPTION The applicant requests approval of a Development Plan to construct a three-story, 38’-6” tall, 24-unit apartment building. The unit breakdown for the apartment building is provided on the table below. The table includes the floor, type of apartment, total number of units and average unit size. 181 CPC – August 9, 2023 County File #CDDP21-03031 Page 5 of 20 Proposed Dwelling Unit Summary Floor Type of Apartment Number of Units Average Unit Size (gross rentable square feet) Building 1st Floor Two-bedroom unit One-bedroom unit 4 4 830 650 Building 2nd Floor Two-bedroom unit One-bedroom unit 4 4 830 650 Building 3rd Floor Two-bedroom unit One-bedroom unit 4 4 830 650 Total 24 Building Design and Height The three-story apartment building will have a modern design with a flat roof with stucco siding in a sandstone color blended in with hard shingle siding in a pearl gray color around the proposed balconies. Window trim will be vinyl style in a sand color. Each level has similar floor plan layouts, with the two-bedroom units located on the outer portions of the building and the one-bedroom units located within the interior of the floor. The building would be comprised of three segments separated by staircase breezeways, joined under one unified flat roof to minimize the overall bulk of the structure. Building design incorporates a rectangular shape to create one cohesive building from top to bottom while the open breezeway at each level adds depth and variation to the exterior of the building. The overall height of the building will be 38’-6” from natural grade and will appear to be 34’ from finished grade. The project also includes various other improvements including: • Parking-related improvements for 34 parking spaces with two ADA accessible spaces and four electric vehicle charging spaces. • Asphalt and permeable pavement are located around the building footprint. • Landscaping would include 25 trees and numerous shrubs throughout the property for a total of 6,600 square feet of landscaping. A new six-foot fence along the rear property line and a six-foot decorative wall along the side property lines. • Retaining walls along the rear of the property • Fire Hydrant • Six long-term bicycle storage lockers and two short-term bicycle storage spaces. • A 13’-7” tall carport that will cover 16 spaces located on the east side of the parcel. • An 8’-8”, approx. 261 square foot, trash enclosure structure. 182 CPC – August 9, 2023 County File #CDDP21-03031 Page 6 of 20 • Four downward-oriented LED streetlight-style lights to be located near the carport to provide site security. • Bioretention Facilities. • Site preparation would include approximately seven cubic yards of cut and 3,803 cubic yards of fill for bioretention treatment facilities and to direct stormwater to off- site drainage infrastructure. • Curb, gutter, sidewalk improvements, and driveway ramp would be constructed along the project frontage on Windhover Way. Parking In accordance with California Density Bonus Law, instead of utilizing the parking requirements of the County Zoning Code, the applicant is providing parking in accordance with Government Code Section 65915(p)(1), which states that qualifying housing developments may provide parking according to the following ratios: 1 Bedroom Units: 1 on-site parking space 2 Bedroom Units: 1.5 on-site parking space According to these ratios, the project is required by state law to provide 30 on-site parking spaces. Here, the project will provide a total of 34 on-site parking spaces. The spaces will include 24 spaces of 9’ x 17’ dimension, six spaces of 9’ x 18’ dimension, and four spaces of 7.5’ x 14.5’ dimension. These will include compact, accessible, and electric vehicle parking. The project proposes 17 parking spaces (16 of which will be covered parking spaces) along the eastern property line, 13 parking spaces along the northern property line, and four compact parking spaces along the entrance. In addition, six long-term bicycle parking spaces and two short-term bicycle parking spaces will be provided. Density Bonus and Inclusionary Housing Ordinance In accordance with California Density Bonus Law, pursuant to Government Code Section 65915(b), the applicant seeks a density bonus for the project. The project would provide 3 affordable units in the housing development—one made available for rent to very-low- income households and two units made available for rent to low-income households. Under state law, the project is eligible for a density bonus. The project has a maximum current density of 22 units under the General Plan Land Use Designation (Multiple-Family Residential High Density (MH). By providing three low-income units (13%), the project is eligible for a 24.5% density bonus (or six additional units). The applicant has requested a density bonus to allow two additional units, for a total of 24 units. Under State Density Bonus Law, the project is also eligible for one development incentive or concession. County Code Section 84-26.14 requires 25 percent of the area to be landscaped 183 CPC – August 9, 2023 County File #CDDP21-03031 Page 7 of 20 and not covered by building, structures, or pavement. The applicant has requested a concession to reduce the open space requirement from 25% to 20.5% open space area within the parcel. Under State Density Bonus Law, the project may also request the waiver or reduction of development standards that would have the effect of physically precluding the development and the increased density. The applicant has requested waivers or reductions of development standards to allow a reduced 2’ side yard setback (where 20’ minimum is required) for parking spaces, a reduced 17.5’ front yard setback (where 25’ minimum is required) for parking spaces, a reduced parking stall size to allow 9’ x 18 and 9’ x 17 parking stalls, (where 9’ x 19’ is required), and 16 covered parking where one-half of the required spaces shall be covered.) The covered parking area is located along the eastern property line of the site. Inclusionary Housing Ordinance Under the County’s Inclusionary Housing Ordinance, the inclusionary housing requirement is 3.3 units (calculated as 15% of 22 units). In addition to the 3 affordable units described above, the applicant has agreed to pay an in-lieu fee of $48,401.10 for the remaining fractional (0.3) inclusionary unit required. Circulation and Access Primary vehicle access to the project site would be from Windhover Way via a driveway that intersects parallel with Windhover Way and the subject parcel. Windhover Way connects to Pacheco Boulevard. Both of these roads are County maintained roads. Windhover Way along the project frontage is approximately 36-foot-wide street within a 56-foot right-of-way. The driveway isle exiting Windhover Way and leading to the parking lot on site will be 26’ wide and will lead into an emergency vehicle hammerhead turnaround. Within the parking lot, the project site will maintain a 25’ parking isle width for the parking spaces along Windhover Way and a 24.5’ parking aisle width for the parking spaces on the east (side) property line. The project proposes to install retaining curbs along the edge of the driveway/parking lot area. VI. CEQA PUBLIC COMMENTS An Initial Study and Mitigated Negative Declaration (MND) for the proposed project were posted for public review between July 11, 2023, and July 31, 2023. Seven comment letters were received during that time from Steve Schmedinghoff, Jesse Ma, Gayle Ansell, Kevin Mulcahy, Charlene Crisafulli-Mulcahy, Contra Costa Water District (CCWD) and the Contra Costa County Fire Protection District. Below is a summary of the comments that address environmentally related issues discussed in the MND, and staff’s responses to those 184 CPC – August 9, 2023 County File #CDDP21-03031 Page 8 of 20 comments. A. Email from Steve Schmedinghoff received on July 17, 2023. 1. Comment: Steve Schmedinghoff’s correspondence lists concerns regarding traffic, parking, property values, privacy and emergency vehicle access. Staff Response: The comments received from Steve Schmedinghoff did not specifically challenge the adequacy of the environmental document. The concerns pertain more to the merits of the project and do not specify inadequacies or otherwise challenge the environmental review. In addition, mitigations and conditions of approval have been included in the MND and the findings and conditions of approval to address the project’s potentially significant impacts on the surrounding community. Many of the issues raised in Steve Schmedinghoff’s letter are addressed in this Staff Report and in the Initial Study, including parking availability, traffic and property value. Section 17 - Transportation of the Initial Study concluded that the project will not have a significant impact on transportation within the project vicinity as the proposed project would have a less than significant impact in relation to vehicle miles traveled. As stated in this Staff Report, the project is subject to parking ratios pursuant to 65915(p) which requires the project to provide 30 parking spaces. The project will provide 34 parking spaces which exceeds the requirement. The project applicant provided a Traffic Report which indicated that the project would have a less than significant impact on current traffic patterns. Section 17 - Transportation subsection (d) of the Initial Study reviewed the project in relation to emergency access. The project is required to comply with the applicable California Fire Code, the California Building Code, the California Residential Code and Local and County Ordinances and adopted standards. All construction plans will be subject to the applicable Fire Code that is in effect at the time when the application for a building permit is submitted. Additionally, the applicant will work with the Fire Protection District to submit construction plans for review and approval prior to building permit issuance. Therefore, the routine review of construction plans will ensure that the proposed project has no potential for adversely impacting existing emergency access to the subject property or other properties within the County. B. Email from Jesse Ma received on July 24, 2023. 2. Comment: Jesse Ma’s correspondence lists concerns regarding building height for emergency services, site drainage and parking and site accessibility. 185 CPC – August 9, 2023 County File #CDDP21-03031 Page 9 of 20 Staff Response: The comments received by Jesse Ma did not specifically challenge the adequacy of the environmental document. Jesse Ma’s correspondence lists concerns that pertain more to the merits of the project and do not specify inadequacies or otherwise challenge the environmental review. As stated in the Staff Report, the project is requesting a Variance for a three-story building with increased height. Staff has made the findings that support the Variance which are included in the Findings and Conditions of approval attached to this Staff Report. As stated in the Staff Report, the new building will be required to comply with all Contra Costa County Fire Protection standards and codes and will be required to obtain approval from the Fire District during the building permit process. This will ensure that the proposed development will meet all fire code requirements. While Jesse Ma did not specifically challenge the environmental document, the Initial Study/Mitigated Negative Declaration Section 10 – Hydrology and Water Quality addresses storm water drainage for the project. The proposed project is designed to meet Division 914 of the County Ordinance Code which requires all storm water entering and or/originating on this property to be collected and conveyed to an adequate natural watercourse or an existing adequate public storm drainage system. The project was reviewed by the County Public Works Department and was determined to be in compliant with County Ordinance Code and with the proposed bioretention facility and will not drain onto surrounding parcels. Lastly, the project proposes four electric vehicle spaces and two ADA stalls with access routes to the proposed building. Per the County Code, 10% of the proposed spaces are required to be electric, therefore a minimum of three spaces are to be required. The applicant is proposing four and thus, exceeds the minimum requirement. C. Email from Michael Cameron of Contra Costa County Fire Protection District on July 19, 2023. 3. Comment: Based on the plans, it appears that the project does not provide aerial fire apparatus access for a building that is over 30 feet tall. Staff Response: The comments received from the Fire Protection District did not specifically challenge the adequacy of the environmental document. The project is required to obtain Fire District approval and to submit construction plans to the Fire District for review and approval. During this process, the Fire District will work with the applicant to ensure that the project meets all requirements that the Fire District will impose on the project including ensuring that the project provides aerial fire apparatus access. Therefore, by working directly with the Fire District, the project will address this 186 CPC – August 9, 2023 County File #CDDP21-03031 Page 10 of 20 concern. D. Letter from the Contra Costa Water District (CCWD) dated July 19, 2023. 4. Comment: The District has reviewed the request and has the following comments: 1. The premise will require its own service connection, meter, fire service, and reduced pressure (RP) backflow prevention device. 2. RP backflow prevention devices are above ground devices, which, in some cases could reduce water pressure to below standard. Proper planning is necessary to ensure backflow prevention devices are located outside the footprint of the building either in the “right of way” or in an easement provided by applicant. A minimum of three-foot clearance is required around all above ground devices with no vertical impediment. Similarly, fire service will also need to be placed above ground and meet this clearance minimum. Previous plans from 2021 showed fire service placed in a vault located below grade. Staff Response: The comments received from the Water District did not specifically challenge the adequacy of the environmental document. Rather, the comments are requesting that the applicant contact and work directly with the Water District to obtain all the necessary permits before obtaining water service. During this time, the Water District will ensure that the project will meet the requirements to obtain water service. The Findings and Conditions of approval of this project include advisory notes that recommend the applicant contact the Water District prior to continuing with the project. E. Email from Gayle Ansell received on July 26, 2023. 5. Comment: Gayle Ansell’s correspondence lists concerns regarding a three-story building. Staff Response: The comments received by Gayle Ansell did not specifically challenge the adequacy of the environmental document. The concerns pertain more to the merits of the project and do not specify inadequacies or otherwise challenge the environmental review. The project is requesting a Variance for a three-story building with increased height. Staff has made the findings that support the Variance which are included in the Findings and Conditions of Approval attached to this Staff Report. F. Email from Kevin Mulcahy received on July 26, 2023 and July 31, 2023. 6. Comment: Kevin Mulcahy’s correspondence lists concerns regarding the density of the units, parking, traffic, height, and the use of concessions/incentives and reductions. Staff Response: The comments received by Kevin Mulcahy did not specifically challenge the adequacy of the environmental document. The concerns pertain more to the merits 187 CPC – August 9, 2023 County File #CDDP21-03031 Page 11 of 20 of the project and do not specify inadequacies or otherwise challenge the environmental review. The project is within the Multiple-Family Residential High Density (MH) Land Use Designation. This General Plan allows for 22.0 to 29.9 multiple-family units per net acre. Based on the site’s acreage of 0.6 net acres, the maximum allowed unit on site is 22 units. However, the Applicant also requested a Density Bonus Request pursuant to Government Code 65915(b)(1)(A). By providing three inclusionary housing, the project would be eligible for the State density bonus of 13.6%, and the total allowable unit county under the MH designation would increase from 22 units to 24 units. Therefore, the project is within the allowed density for the site. In the Initial Study Section 17 -, Transportation, the project was found to have a less than significant impact in regard to traffic. A traffic study was performed and found that the project will have a lower VMT rate than the significance threshold and therefore, would have a less than significant impact on traffic related impacts. The project requests a reduction in development standards pursuant to Government Code 65915(p) for parking ratios. Under these ratios, the project is required to provide 30 parking spaces. The project is providing 34 parking spaces which exceeds the requirement and is requesting a reduction in parking stall sizes pursuant to Government Code 65915(e) which allows an applicant to request reduction in development standards. Lastly, an Initial Study was prepared and evaluated the project under the California Environmental Quality Act. The Initial Study found that the project does not have significant adverse impacts, and therefore, the project is allowed to request concessions/incentives and reductions in development standards. F. Email from Charlene Crisafulli-Mulcahy received on July 26, 2023. 7. Comment: Charlene Crisafulli-Mulcahy’s correspondence lists concerns regarding parking, parking stall size, building height, density, traffic and trucked in soil. Staff Response: The comments received by Charlene Crisafulli-Mulcahy did not specifically challenge the adequacy of the environmental document. The concerns pertain more to the merits of the project and do not specify inadequacies or otherwise challenge the environmental review. The project requests a reduction in development standards pursuant to Government Code 65915(p) for parking ratios. Under these ratios, the project is required to provide 30 parking spaces. The project is providing 34 parking spaces which exceeds the requirement. In regard to parking stall size, pursuant to Government Code 65915(e), an applicant is allowed to request reductions in development standards. As stated in this Staff Report, the applicant has requested a reduction in parking stall sizes and will be providing twenty-four 9’ x 17’ dimension parking spaces and six 9’ x 18’ dimension parking spaces. Chapter 82-16 – Off-Street 188 CPC – August 9, 2023 County File #CDDP21-03031 Page 12 of 20 Parking of the County Ordinance requires an 8’-6” space width and 18’ space depth for each space for parking spaces of ninety degrees. The project does provide multiple spaces that meet the dimension requirements. Staff researched numerous pick-up truck brands including the following: Chevrolet, Dodge, Ford, GMC, Honda, Hyundai, Isuzu, Jeep, Mazda, Mercedes, Mitsubishi, Nissan, Renault, Rivian, Toyota and Volkswagen and found that the average dimension of a pick-up truck is 17.7 feet long and 6.3 feet wide. Therefore, the average pick-up truck would be able to fit within many of the proposed parking space dimensions on the site. Additionally, the Off-Street Parking ordinance of the County Code does not require dedication of spaces specifically for pick-up trucks. The project is requesting a Variance for a three-story building with increased height. Staff has made the findings that support the Variance which are included in the Findings and Conditions of approval attached to this Staff Report. The project is within the Multiple-Family Residential High Density (MH) Land Use Designation. This General Plan allows for 22.0 to 29.9 multiple-family units per net acre. Based on the site’s acreage of 0.6 net acres, the maximum allowed units on site is 22 units. However, the Applicant also requested a Density Bonus Request pursuant to Government Code 65915(b)(1)(A). By providing three inclusionary housing, the project would be eligible for the State density bonus of 13.6 percent, and the total allowable unit county under the MH designation would increase from 22 units to 24 units. Therefore, the project is within the allowed density for the site. In the Initial Study Section 17 -, Transportation, the project was found to have a less than significant impact in regard to traffic. A traffic study was performed and found that the project will have a lower VMT rate than the significance threshold and therefore, would have a less than significant impact on traffic related impacts. Section 7 - Geology and Soils of the Initial Study reviewed the presence of undocumented fill on the site. The initial study includes two mitigation measures based on the County Geologist’s comment to address all undocumented fill and to remedy the decision. These mitigation measures address the project’s potentially significant impacts on undocumented fill which are included as conditions of approval. VII. APPEAL OF ZONING ADMINISTRATOR’S FEBRUARY 22, 2023 DECISION During the appeal period following approval by the Zoning Administrator, one appeal was received from Joe Hise. In the correspondence received on February 27, 2023, Joe Hise filed an appeal on behalf of the signed neighbors included on the letter, appealing the Zoning Administrator’s decision. The concerns raised in the letter of appeal, and staff’s responses, are summarized as follows: 189 CPC – August 9, 2023 County File #CDDP21-03031 Page 13 of 20 1. Summary of Appeal Point #1: The appellant expressed concerns that the proposed project does not meet the Multiple Family Residential District (M-29), more specifically County Code Section 84-26.802 – which provides a maximum height of buildings or structures within the M-29 Zoning District. Staff Response: County Code Section 84-26.802 requires all buildings or structures to have a maximum height of thirty feet in height or twenty feet in height when the building is within fifty feet of a single-family residential district. Parcels directly northeast of the project site are zoned R-6 while parcels directly northwest, east and south are zoned M-29. The proposed building footprint is located more than 50 feet from the nearest R-6 zoned property, and therefore, would not be subject to the twenty feet height max. However, the proposed building will be 38’-6” and is requesting a variance for relief from the height requirement of 30 feet. Variance requests are allowed per County Code 84-26.2002 and Staff made the required Variance findings which are discussed in the findings and conditions of approval section of this staff report. Because the required Variance findings are made, the applicant is allowed to request relief from the height restriction, and the project is granted relief from the height requirements. Overall, the project meets the requirements of the M-29 Zoning District. 2. Summary of Appeal Point #2: The appellant expressed concerns that the project should not be exempt from CEQA. Staff Response: Since the Zoning Administrator’s decision, staff determined that it was appropriate to conduct additional environmental review of the project under the California Environmental Quality Act. The County prepared an Initial Study for the project (SCH No. 2023070169) which evaluated the environmental impacts of the proposed project. During the preparation of the Initial Study, the County identified environmental factors that would have been potentially affected by this project and that with the incorporation of mitigation measures, the project would not result in any significant impacts to the environment. The Mitigated Negative Declaration indicated that no significant environmental impacts will be created by the proposed project. Therefore, the project was reviewed under the CEQA guidelines and was determined to have a less than significant environmental impact. 3. Summary of Appeal Point #3: The appellant expressed concerns that the project needs to be reviewed by the Mt. View Sanitary District. Staff Response: The project was referred to the Mt. View Sanitary District for comments to which they replied in a letter submitted to staff on November 17, 2021. The comments from the Sanitary District include requiring the applicant to submit 190 CPC – August 9, 2023 County File #CDDP21-03031 Page 14 of 20 development plans prepared and stamped by a California Registered Civil Engineer to the District for review of any sewer improvements. Additionally, in the Advisory Notes of the Findings and Conditions of Approval section, the applicant is strongly encouraged to contact the Sanitary District for their requirements. During the building permit process, the applicant will need to obtain Sanitary approval for all construction plans before any building permits are issued. Therefore, the project will need to obtain Sanitary District approval and will be required to obtain any permits required by the Sanitary District during their review process. 4. Summary of Appeal Point #4: The appellant expressed concerns about potential drainage issues from 98 Windhover Way and how the wall on the Pacheco side of the site would affect the surrounding properties. Staff Response: 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 waters to an adequate natural watercourse. According to a discussion with Staff from the Department of Public Works, there is no evidence that the drainage pattern at 98 Windhover Way currently drains onto the subject parcel. The County elevation date contours imply that stormwater should naturally drain southeast from 98 Windhover Way, avoiding the proposed project parcel. To further prevent any drainage problems, the project is proposing drainage upgrades which are consistent with development of this nature. The property slopes from the northwest corner to the southeast corner, away and considerably below street grade. The project will pad up, raising the grade of the site which will further prevent any unwanted off-site discharge. The project plans to direct stormwater runoff from the site to be captured in a bioretention facility onsite which discharges to an existing 18” storm drain in Windhover Way, effectively diverting the onsite flows. Section 914-2.004 of the County Ordinance prohibits the diversion of surface waters from any development. The applicant has requested an exception from the Advisory Agency (Contra Costa County Public Works Department) per section 92- 6.002 of the County Ordinance Code. The Public Works Department reviewed the proposed project and is not opposed to granting the applicant an exception from the collect and convey requirements of the County Ordinance Code because on-site drainage facilities will be installed to tie into the existing storm drain in Windhover Way to the west, drainage infrastructure already existing within the WInhover Way 191 CPC – August 9, 2023 County File #CDDP21-03031 Page 15 of 20 right-of-way which makes draining towards Windhover Way the most appropriate direction and the capacity of the downstream drainage system will be verified to ensure it is sufficient to accommodate the additional runoff created by the project. If the off-site conveyance system, ultimate drainage facility or natural watercourse to which stormwater is proposed to be diverted is inadequate, the applicant shall be responsible for all costs related to the construction and/or right-of-way acquisition related to any necessary improvements to make the system adequate. The proposed wall which is called out on Sheet L-1 is a landscaping six-foot-tall masonry wall. A visual look for this is on Sheet L-2 item 5. This is not a retaining wall as it does not hold up any fill and will be treated like a fence. A six-foot-tall masonry decorative wall will be required to obtain a building permit. The grading plan Sheet C2.0 contains elevations and details on all retaining walls on the site. Detail 4 on Sheet C2.0 includes call outs for WB (Wall Bottom) and WT (Wall Top) and includes elevation numbers. Therefore, Staff concludes that the project provides enough information to address any drainage and wall concerns. 5. Summary of Appeal Point #5: The appellant expressed concerns that the proposed Olive Trees to be removed were incorrectly surveyed. Staff Response: During the County Zoning Administrator Public Hearing on February 22, 2023, the Applicant requested to amend the Tree Permit application to preserve the Olive Trees (#40, 41, 42) as indicated on Sheet L-1 of the project plans to address this appeal point. As a result, condition of approval #26 was added by the County Zoning Administrator to ensure that these three trees are preserved. While work within the dripline of these three Olive Trees may occur, Staff has included condition of approval #27 to require a security for possible damage to trees intended for preservation, condition of approval #28 which prohibits removal of any tree without an approved building or grading permit and conditions of approval #29-38 which are arborist recommended best management practices. Therefore, with the required conditions of approval, the applicant will be required to preserve and protect the required trees. 6. Summary of Appeal Point #6: The appellant expressed concerns that the project does not provide parking for pickup trucks nor provides enough parking in general. Staff Response: The project will provide a total of 34 parking spaces consisting of 9’ x 17’, 9’ x 18’, 7.5’ x 14.5’ dimensions. As part of the applicant’s Density Bonus request, which is discussed in this Staff Report, the applicant is requesting parking ratios 192 CPC – August 9, 2023 County File #CDDP21-03031 Page 16 of 20 pursuant to Government Code 69515(p). Government Code 65915(p): Upon the request of the developer, no city, county, or city and county shall require a vehicular ratio, inclusive of handicapped and guest parking, of a development meeting the criteria of subdivision (b) that exceeds the following ratios: (A) Zero to one bedrooms: 1 off-street parking space (B) Two to three bedrooms: 1.5 off-street parking space Based on the number of bedrooms proposed, 30 parking spaces would be required for the project. Thus, the project proposes 34 parking spaces, which meets this requirement. Because the proposed project submitted a Density Bonus request, the applicant is allowed to request parking ratios pursuant to Government Code 65915(p), and thus, the project provides enough parking. The project is providing twenty-four 9’ x 17’ dimension parking spaces and six 9’ x 18’ dimension parking spaces. Pursuant to Government Code 65915(e), an applicant is allowed to request reductions in development standards for parking stall sizes. Additionally, Chapter 82-16 – Off-Street Parking of the County Ordinance requires an 8’-6” space width and 18’ space depth for each space for parking spaces of ninety degrees. The project does provide multiple spaces that meet the dimension requirements. Staff researched numerous pick-up truck brands including the following: Chevrolet, Dodge, Ford, GMC, Honda, Hyundai, Isuzu, Jeep, Mazda, Mercedes, Mitsubishi, Nissan, Renault, Rivian, Toyota and Volkswagen and found that the average dimension of a pick-up truck is 17.7 feet long and 6.3 feet wide. Therefore, the average pick-up truck would be able to fit within many of the proposed parking space dimensions on the site. Additionally, the Off-Street Parking ordinance of the County Code does not require dedication of spaces specifically for pick-up trucks. 7. Summary of Appeal Point #7: The appellant expressed concerns that due to the proposed setback for the carports noise from the parked vehicles will impact surrounding neighbors. Staff Response: The project applicant is proposing to install a new six-foot tall masonry wall along the edge of all parking areas. The proposed parking area that the appellant is concerned about is located 4.5’ from the side yard. This wall will act as a sound buffer to reduce sources of noise generated from the parking areas that would otherwise reach the surrounding parcels. Additionally, a noise assessment was prepared by Illingworth & Rodkin, Inc on May 10, 2022, to evaluate the compatibility of the proposed project with respect to the noise levels resulting from the proposed project. The study used a series of short-term noise measurements and long-term 193 CPC – August 9, 2023 County File #CDDP21-03031 Page 17 of 20 measurements on Wednesday, April 27, 2022. The study found that existing noise levels measured in these areas ranged from 55 to 59 dBA and that with the introduction of the project, the unmitigated noise level would reach 56 to 60 dBA by 2040. The study concludes that “future exterior noise levels would not exceed 60 dBA and within the normally acceptable noise and land use compatibility range identified for residential land uses.” Therefore, Staff concludes that noise impacts from parked vehicles will be negligible and generally consistent with typical noise uses found in multiple-family residential development. 8. Summary of Appeal Point #8: The appellant expressed concerns that property values next to the proposed project will decline. Staff Response: The project site is currently a dirt/grassy vacant lot with no landscaping features. The proposed project will construct a new 24-unit apartment building which includes proposed landscaping for the site. The proposed apartment building and landscaping will improve the site’s character, taking a vacant lot and providing residences for Martinez area. This will enhance the surrounding property values as the surrounding properties will no longer be next to a vacant lot that is overgrown with unkept vegetation. The County designated this site as Multiple-Family Residential-High Density in the Land Use Element of the County General Plan in anticipation that this site would be used for multiple housing units as this element allows for high densities of multiple- family units per acre. The proposed project would be compatible with this Land Use Element as it proposes a multi-family apartment building which was the intent of the General Plan. Additionally, the Housing Element Goals listed on Table 6-1 state the following: 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 affordable to extremely-low-income households. The proposed project would be consistent with these specific goals of the Housing Element in that the project provides affordable housing while turning a vacant site into an attractive housing opportunity. Table 6-24 of the Housing element identifies housing needs by income for Cities in Contra Costa County. Martinez is identified to need 124 very low income and 72 low-income units. The proposed project will help the County meet those numbers by providing affordable housing to the area. Furthermore, there is no evidence provided that the multiple-family residential development would negatively affect nearby single-family home values. Therefore, because the project is converting a vacant lot into a land use that would add to the housing inventory for the County, Staff concludes that property values will not be 194 CPC – August 9, 2023 County File #CDDP21-03031 Page 18 of 20 negatively affected in the project area. 9. Summary of Appeal Point #9: The appellant expressed concerns that the proposed project will have specific adverse impacts and does not qualify for reduced development standards under Density Bonus Law. Staff Response: The project is subject to Chapter 822-4, Inclusionary Housing Ordinance. Pursuant to Section 822-4.402(a) of the County Ordinance, a proposed residential development of 22 rental units, at least fifteen percent of the rental units shall be developed and rented as inclusionary units. The applicant has submitted a Inclusionary Housing Plan which proposes to construct three inclusionary units within the housing development. Two units will be available to lower-income households (80% Area Median Income (AMI)), and one unit will be available to a very low-income household (50% AMI). The fractional unit of 0.3 would be satisfied with the payment of a partial in-lieu fee. Included in their inclusionary housing plan, the applicant submitted a density bonus request. With the current proposal, the applicant is eligible for a 24.5% density bonus as the applicant is proposing to build on-site three lower-income units. The applicant density bonus request proposes a density bonus of 2 units with requested concessions and various reductions in development standards. Pursuant to Government Code 65915, the Applicant has proposed a housing development that will contain units that comply with Government Code 65915(b)(1)(A) and may request one concession/incentive for providing 13 percent of the total units of a housing development for lower-income households within the development. For use of the one concession, the Applicant requested reduced open space requirement pursuant to Government Code 65915(d). Additionally, the Applicant has requested parking ratios based on Government Code 65915(p) for a reduced parking requirement. The request also includes reductions in development standards pursuant to Government Code 65915(e) for reduced parking stall sizes, reduced parking setbacks and reduced covered parking. Staff has reviewed the request for the reduction of development standards and has determined that none of the waivers or reductions of development standards would have a specific, adverse impact as defined in paragraph (2) of subdivision (d) of Section 65589.5. More specifically, a specific, adverse impact is a “significant, quantifiable, direct and unavoidable impact, based on objective, identified written public health or safety standards, policies, or conditions as they existed on the date the application was deemed complete.” As stated in this Staff Report, the project was reviewed by multiple outside agencies, contains numerous reports and studies in relation to traffic, noise, geology and trees and is consistent with the zoning ordinance and general plan land use designation for this site. Moreover, an Initial Study/Mitigated Negative Declaration was prepared for the project which evaluated the project under the California Environmental Quality Act and was found to have no significant 195 CPC – August 9, 2023 County File #CDDP21-03031 Page 19 of 20 impacts with the incorporation of the mitigation measures. Therefore, Staff concludes that the project will not present a “specific, adverse impact.,” as stated in Government code Section 65589.5(d)(2). 10. Summary of Appeal Point #10: The appellant expressed concerns that the project will create traffic impacts on Windhover Way and Pacheco Blvd and that a traffic study should be performed. Staff Response: The applicant provided a Transportation Impact Analysis (TIA) report prepared by W-Trans dated September 6, 2022 and received by Staff on September 7, 2022. The purpose of the report was to document the existing conditions and evaluate the project’s potential transportation impacts and effect on traffic operations. The proposed project is expected to generate an average of 162 trips per day, including 10 trips during the a.m. peak hour and 12 during the p.m. peak hour. These new trips represent the increase in traffic associated with the project. The study also included a traffic signal warrant analysis to determine the potential need for a traffic signal at the intersection of Pacheco Blvd and Windhover Way. The study concluded that the intersection is “expected to continue operating at the same Level of Service upon the addition of project-generated traffic” and recommended that “no further action is recommended,” in relation to a new traffic signal. The study also reviewed Vehicle Miles Traveled (VMT). According to the Contra Costa County Travel Demand Model estimates, the Countywide home-based average VMT per resident is 19.4 miles. Concurring with guidance provided in the TIA, a project located anywhere in the County which generates a VMT that is 15% or more below this value, or 16.5 miles per resident, should be expected to have very little VMT impact and would not require further VMT analysis. The TIA Table 4 states that the project VMT rate would be 16.0. Therefore, the project is expected to have a VMT per capita less than 15% below the countywide VMT per resident and no further VMT analysis is required. Moreover, the Transportation Planning section of the Department of Conservation and Development reviewed the TIA report and determined that it was adequate for the site. To address any future concerns regarding traffic, during the County Zoning Administrator Meeting on February 22, 2023, the County Zoning Administrator added a new condition of approval #46 to require a detailed Traffic Analysis within 6 months after the Certificate of Occupancy permit has been issued. This will allow the County to determine if traffic signal timing change will be needed to increase the frequency and time of vehicle gaps on Pacheco Boulevard. Therefore, Staff concludes that the project will not create significant traffic impacts in this area. 196 CPC – August 9, 2023 County File #CDDP21-03031 Page 20 of 20 VIII. 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 M-29 Zoning District. The project is consistent with the established area as muti-family residential units are a common occurrence. The design and use of the proposed apartments is consistent with the other uses in the immediate area. The project will also provide additional needed housing and affordable housing units. In addition, an environmental analysis of the project has been administered, and it was found that the proposed project would not have a significant impact on the environment with the incorporation of specific mitigations. Therefore, Staff recommends that the County Planning Commission deny the appeal and approve County File #CDDP21-03031, based on the attached findings and subject to the attached conditions of approval.

Zoning Administrator Staff Report and Attachments 7. Plans 8. Power Point Slides 197 FINDINGS AND CONDITIONS OF APPROVAL FOR COUNTY FILE #CDDP21-03031; WEST COAST LAND AND DEVELOPMENT, INC – PAMELA WEST (APPLICANT & OWNER). I. FINDINGS A. Growth Management Performance Standards 1. Traffic: Policy 4-c under Growth Management Program (GMP) requires a traffic impact analysis be conducted for any project that is estimated to generate 100 or more AM or PM peak-hour trips based upon the trip generation rates as presented in the Institute of Traffic Engineers (ITE). A project generating less than 100 peak-hour trips generally will not create or exacerbate any current traffic problems. The project provided a Transportation Impact Analysis prepared by W-Trans which concluded that the project would generate 10 AM trips and 12 PM trips. Since the proposed development would yield less than 100 peak-hour AM or PM trips, a project-specific traffic impact analysis is not required and the project is assumed to have a less than significant impact on the circulation system in the project vicinity. 2. Water: The GMP requires new development to demonstrate that adequate water quantity can be provided. The subject property currently receives water service from the Contra Costa Water District (CCWD), and the district has stated that water service is available for the project as the entire site is within the water districts service area. 3. Sanitary Sewer: The GMP requires new development to demonstrate that adequate sanitary sewer service is available. The project site currently receives sanitary sewer service from the Mountain View Sanitary District (MVSD) and MVSD sewer mains in the area are available for the project. The district provided a letter stating that the applicant shall submit a sewer permit application with the district for review and approval. 4. Fire Protection: The fire protection standards under the GMP require that a fire station be within one and one-half miles of development in urban, suburban, and central business district, or requires that an automatic fire sprinkler system be installed to satisfy this standard. The project site is within the Contra Costa County Fire Protection District jurisdiction and is located approximately six mins drive time from Contra Costa County Fire Station #14 located at 521 Jones Street in Martinez. The project is required to comply with the applicable provisions of the California Fire Code, the California Residential Code, and Contra Costa County Ordinances that pertain to emergency access, fire suppression systems, and fire detection/warning systems. When it comes time to submit for building permits, the construction drawings would have to be reviewed and approved by the Contra Costa County Fire Protection District. 5. Public Protection: Public protection standards under the GMP require that a Sheriff Facility standard of 155 square feet of station area and support facilities per 1,000 in 198 CPC – August 9, 2023 County File #CDDP21-03031 Findings and COA Page 2 population shall be maintained within the unincorporated area of the County. Based on the United States Census Bureau’s estimate of 2.48 persons per household (between 2017-2021) for Martinez, the project would potentially increase the population by an estimated 89.28 people. Since the project would result in a relatively small change in population, the project would not impact the County’s ability to maintain a Sheriff facility standard of 155 square feet of station area and support facilities per 1,000 members of the population. Thus, the project would not significantly affect the provision of police services to the Martinez area. 6. Parks and Recreation: As the project will add to the County’s population, Condition of Approval (COA) #21 and #22 requires the project proponent to pay applicable Park Impact and Park Dedication in-lieu fees for the new units. These fees, in conjunction with all other Park Dedication fees collected for development within the County, will be used in part to purchase new park land and upgrade existing community parks as determined appropriate by the Board of Supervisors. 7. Flood Control and Drainage: The project is located in Zone X, as designated on the Federal Emergency Management Agency’s Flood Insurance Rate Maps. The project is required to meet collect and convey requirements of the County Subdivision Ordinance Title 9, by constructing the necessary drainage improvements, or obtaining necessary exceptions to the code. The applicant must also comply with the County’s National Pollutant Discharge Elimination System (NPDES) Permit and Stormwater Management and Discharge Control Ordinance, Title 10, for stormwater treatment. With the included exception to Title 9, the new drainage improvements will both meet stormwater discharge requirements for stormwater treatment, while also accommodating all rainwater runoff generated by the project, as required by Title 9. B. Development Plan Findings 1. Required Finding: The proposed project is consistent with the purpose of the zoning district: Project Finding: The purpose of the M-29 Multiple Family Residential (M-29) district is to allow multiple-family residential development to be compatible as much as possible with nearby single-family residential zoning. The project will largely conform to the M-29 District development standards related to setbacks, lot coverage, and other standards. Variances to the development standards meet the intent of the standards, as required by the Variance findings. The project also has submitted a Density Bonus Request and is requesting parking ratios pursuant to Government Code 65915(p) and multiple reduction to development pursuant to Government Code 65915(e). With these requests, the 199 CPC – August 9, 2023 County File #CDDP21-03031 Findings and COA Page 3 proposed project creates a multi-family apartment complex that is a permitted use under 84-26.402(3). 2. Required Finding: The proposed project is architecturally compatible with other uses in the vicinity, both inside and outside the zoning district. Project Finding: Given the density of housing development in the area (townhomes, duplexes, single-family residence), the proposed design does not conflict with the surroundings in building mass or height. The architectural style in this area of the County can be described as a diverse collection of Ranch, Mediterranean, Spanish Revival, and contemporary modern styles. The project’s contemporary design would be comprised of three segments separated by staircase breezeways, joined under one unified flat roof to minimize the overall bulk of the structure. Building design incorporates a rectangular shape with all exterior walls of each level at the same location to create one cohesive building from top to bottom while the open breezeway at each level adds depth and variation to the exterior of the building. The façade of the building will have variation with sandstone color stucco alternating with pearl gray shingle siding. The colors of the building will be designed to compliment the surrounding natural palette of the area. C. Variance Findings: 1. Required Finding: Any variance authorized shall not constitute a grant of special privilege inconsistent with the limitations on other properties in the vicinity and the respective land use district in which the subject property is located. Project Finding for Height: The variance request is to allow a 38’-6” tall building (where 30 feet is the maximum allowed). Given that the height is due to unique topographical characteristics and drainage restrictions, granting of the variance for the building height would not be considered a grant of special privilege. In order to meet drainage requirements that require stormwater to drain to adequate stormwater infrastructure at Windhover Way, the rear of the lot must be padded (i.e., filled with dirt to raise the grade). Currently, the rear of the lot is almost nine feet lower than the frontage (Windhover Way). The project will pad almost nine feet towards the rear to bring the site level and 4’-6” of padding under the building itself. This extensive amount of padding raises the finished grade under the rear of the building, resulting in a height that exceeds the 30-foot standard when measured from natural grade. Complying with the height restriction would present a practical difficulty because the project is required to have drainage improvements due to topography. Additionally, in order to meet the required density of the General Plan Land Use Designation for this site, the project was required to add more units, which prompted the height increase. Strict application of the zoning code would present an unnecessary burden on the site by reducing the amount of units 200 CPC – August 9, 2023 County File #CDDP21-03031 Findings and COA Page 4 on site by eight, which would result in a total of 16 units, which is on the lower end for the General Plan Land Use Designation. For these reasons, the height of the building is not a grant of special privilege inconsistent with the limitations of other properties in the vicinity and respective land use district. Project Finding for Driveway Aisle Width: The variance request is to allow for a 24.5’ driveway aisle width (where 25’ is the minimum required) for a driveway aisle with parking spaces of ninety degrees located on the eastern side of the multi-family apartment building. Granting the variance for the reduced driveway aisle width would not be a grant of special privilege. The irregular flag- shaped property has an approximately 48-foot-wide by 72-foot-long strip of land that extends access to Windhover way. The strip of land presents a unique restriction only applicable to this site. The unique shape unreasonably limits development on the property in a way that the required density is only feasible with reduced driveway aisle width. In order to facilitate and maintain circulation and to allow the site to provide adequate parking spaces, the driveway aisle width needs to be slightly reduced. Complying with the ordinance for driveway aisle width would present a practical difficulty because it would reduce the amount of parking on the site and limit the total developable area. For these reasons, the reduced driveway aisle width is not a grant of special privilege inconsistent with the limitations of other properties in the vicinity and respective land use district. 2. Required Finding: That because of special circumstances applicable to the subject property because of its size, shape, topography, location or surroundings, the strict application of the respective zoning regulations is found to deprive the subject property of rights enjoyed by other properties in the vicinity and within the identical land use district. Project Finding for Height: Given that the additional height is due to unique topographical characteristics and drainage restrictions, granting of the variance for the building height is based on special circumstances. In order to meet drainage requirements that require stormwater to drain to adequate stormwater infrastructure at Windhover Way, the rear of the lot must be raised by padding from approximately 9 feet at the rear property line to 4’-6” underneath the building. Given that the site slopes away from Windhover Way, the building is required to be raised to address drainage issues. Thus, due to these special circumstances, the strict application of zoning regulations would deprive the subject property of rights enjoyed by other properties developed as multiple-family projects. Project Finding for Driveway Aisle Width: The variance request is to allow for a 24.5’ driveway aisle width (where 25’ is the required minimum). The irregular flag-shaped 201 CPC – August 9, 2023 County File #CDDP21-03031 Findings and COA Page 5 property has a 48-foot-wide by 72-foot-long strip of land that extends access to Windhover Way. This unique shape limits the placement and development of a driveway aisle width on the property as there are already numerous other constraints. To provide a driveway aisle for parking spaces to be accessed, the only feasible location is between the parking spaces. The flagged driveway results in additional area on the lot that must be paved in order to reach the larger developable portion of the lot. Thus, a 25’ driveway aisle would not be feasible while also providing parking, open space, covered parking and space for the building. Thus, due to these special circumstances, the strict application of the zoning regulations would deprive the subject property of rights enjoyed by other properties developed as multiple-family projects. 3. Required Finding: That any variance authorized shall substantially meet the intent and purpose of the respective land use district in which the subject property is located. Project Finding for Height: Height limits are applied to provide an orderly residential development pattern and, adequate air and light between neighboring development. The 8’-6” of additional height (4’ if measured from finished grade) would substantially meet the intent and purpose of the respective 30-foot height maximum as all building setbacks are met and exceeded. The building would maintain separation from neighboring properties. The variance request will allow for the project to address drainage and topography issues without burdening the applicant. Therefore, it is reasonable to believe that the height would not have a detrimental effect on the adjoining properties and meet the intent and purpose of the respective land use district. Project Finding for Driveway Aisle Width: The variance request is to allow for a reduced 24.5’ driveway aisle width (where 25’ is the minimum required). The driveway aisle width allows for cars to maneuver in and out of parking spaces. The proposed driveway aisle width is only 0.5’ less than the minimum requirement. Due to site constraints, the project has balanced the need to provide the full driveway aisle width with the need to provide for adequate parking spots and landscaping requirements. The loss of 0.5’ les for a driveway aisle width will not have a detrimental effect on the adjoining properties and meet the intent and purpose of the respective land use district. 4. Findings for Granting an Exception Per Section 92-6.002: Request for an exception from Title 9 Offsite Collect and Convey Diversion requirements (Section 914-2.0040) 1. Required Finding: That there are unusual circumstances or conditions affecting the property. 202 CPC – August 9, 2023 County File #CDDP21-03031 Findings and COA Page 6 Project Finding: The property slopes from the northwest corner to the southeast corner, away and considerably below street grade. There is no storm drain or easement at the lowest corner of the site. On-site drainage facilities will be installed to tie into the existing storm drain on Windhover Way to the west. The storm drain is deep enough to allow for gravity drainage from the stormwater treatment facilities but was not originally intended to accept stormwater runoff from this site. Considering this site’s unusual circumstances and conditions, an exception from the County Ordinance Code’s prohibition regarding diversions would be required. 2. Required Finding: That the exception is necessary for the preservation and enjoyment of a substantial property right. Project Finding: The diversion of stormwater is necessary to connect the project to stormwater facilities in the area. A connection at the southeast corner of the property is not currently possible, meaning this infill project is not feasible unless the exception is granted. Additionally, as described above, the drainage infrastructure already exists within the Windhover Way right-of-way making this the most appropriate location. 3. Required Finding: That the granting of the exception will not be materially detrimental to the public welfare or injurious to other property in the territory in which the property is situated. Project Finding: Capacity of the downstream drainage system will be verified to ensure it is sufficient to accommodate the additional runoff. Additionally, stormwater would be directed to existing infrastructure used by other properties in the area. Therefore, the exception will not be materially detrimental to the public welfare or injurious to other properties in the territory in which the subject property is situated. The applicant will be required to provide a drainage report to verify the adequacy of the downstream drainage system. If the receiving system is found to be inadequate the applicant shall be required to improve the system to make it adequate. 5. Tree Protection and Preservation Findings: Required Factors for Granting Tree Permit: The Zoning Administrator is satisfied the following factors as provided by County Code Section 816-6.8010 for granting a tree permit have been satisfied: • 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. 203 CPC – August 9, 2023 County File #CDDP21-03031 Findings and COA Page 7 • Where the arborist or forester report has been required, and the director is satisfied that the issuance of a permit will not negatively affect the sustainability of the resource. The project proposes to remove tree #35, 36, 37 and 38. The project proposes to work within the dripline of tree # 40, 41 and 42. All feasible efforts have been made to retain the maximum number of trees and that development of this project cannot be reasonably accommodated on other parts of the property due to the shape and orientation of the property. The trees are required to be removed in order for the appropriate infrastructure to be built to support a project of this size. Development on this property can not occur without the removal of trees. An arborist report was provided which concluded that the trees to be removed are moderate to low health. California Environmental Quality Act (CEQA) Finding In accordance with CEQA Guidelines, Section 15071 and Section 15072, a Mitigated Negative Declaration/Initial Study (MND) was prepared and published for the project. The 20-day public review period for the MND started on July 11, 2023, and ended on July 31, 2023. Seven public comments were received during the public review period for the MND. The comments received did not specifically challenge the adequacy of the environmental document. Neither the comment nor the staff response to the comment result in any changes to the MND, and the impacts, mitigation measures, and findings of the MND are unchanged. On the basis of the whole record before it, including the MND, and in accordance with Section 15074, the County Planning Commission finds that: • There is no substantial evidence that the project with the proposed mitigation measures will have a significant effect on the environment; • The MND reflects the County’s independent judgement and analysis; • The MND is adequate and complete; and • The MND has been prepared in compliance with the California Environmental Quality Act (CEQA) and the State and County CEQA guidelines. Pursuant to CEQA Section 15097, a Mitigation Monitoring Program has been prepared, based on the identified impacts and mitigation measures in the MND. The Mitigation Monitoring Program is intended to ensure that the mitigation measures identified in the MND are implemented. All mitigation measures are included in the Conditions of Approval for the project. 204 CPC – August 9, 2023 County File #CDDP21-03031 Findings and COA Page 8 II.

This project is subject to Chapter 822-4, Inclusionary Housing Ordinance. Terms and definitions regarding the Inclusionary Housing Ordinance are pursuant to this chapter. Pursuant to Section 822-4.402(a) of the County Ordinance Code, in a residential development of 22 rental units, at least fifteen percent of the rental units shall be developed and rented as inclusionary units. The applicant, owner, and/or developer (Applicant) is required to construct 3.3 inclusionary units for the project. The Applicant has submitted a revised Inclusionary Housing Plan received December 27, 2022, which proposed to construct three inclusionary units within the housing development. Two units will be available to lower- income households (80% Area Median Income (AMI)), and one unit will be available to a very low-income household (50% AMI). The fractional unit of 0.3 would be satisfied with the payment of a partial in-lieu fee. The Applicant submitted a revised density bonus request with their revised inclusionary housing plan received December 27, 2022. As described in the HCI April 19, 2022, memo, the Applicant is eligible for a 24.5% density bonus as the Applicant proposed to build on-site three lower-income units or 13% of the units in the housing development as affordable to lower-income households. For this project, the inclusionary housing units are also the lower income units that qualify the project for a density bonus. The Applicant’s Inclusionary Housing Plan and density bonus request propose a density bonus of 2 units, or a 9% bonus, with one requested concession and various reductions in development standards, bringing the total number of units in the project from 22 to 24. Density Bonus – Concession/Incentive 207 CPC – August 9, 2023 County File #CDDP21-03031 Findings and COA Page 11 Pursuant to Government Code 65915, the Applicant has proposed a housing development that will contain units that comply with Government Code 65915(b)(1)(A) and may request one concession/incentive for providing 13 percent of the total units of a housing development for lower-income households within the development. For use of the one concession, the Applicant requested reduced open space requirement pursuant to Government Code 65915(d). Additionally, the Applicant has requested parking ratios based on Government Code 65915(p) for a reduced parking requirement. The request also includes reductions in development standards pursuant to Government Code 65915(e) for reduced parking stall sizes, reduced parking setbacks and reduced covered parking. The County accepted the Applicant’s request for reductions in development standards for the following: Density Bonus – Parking Ratio • Parking ratios pursuant to 65915 (p). • 1 Bedroom Units = 1 off-street parking space (where 1.5 spaces are required) 2 Bedroom Units = 1.5 off street parking space (where 2 spaces are required) Density Bonus – Reduction of Development Standards • Parking stall sizes of 9 feet x 18 feet and 9 feet x 17 feet (where 9 feet x 19 feet is required) • Front Parking setbacks of 17.5 feet (where 25 feet minimum is required). • Side Parking setbacks of 2 feet (where 20 feet minimum is required). • 16 total covered parking (where one-half of the required spaces shall be covered). The County accepted the Applicant’s request for one concession, as follows: • Open space requirement of 20% (where the open space requirement is 25% of land area, with 75% of that area landscaped) Inclusionary Housing and Density Bonus Developer Agreement 12. At least 90 days prior to CDD-stamp approval of plans for the issuance a building, demolition, or grading permit, whichever occurs first, and with the filing of a condition of approval compliance review, the Applicant shall initiate the County’s preparation and execution of an Inclusionary Housing and Density Bonus Housing Agreement (Agreement), form to be provided by the County, with the County pursuant 208 CPC – August 9, 2023 County File #CDDP21-03031 Findings and COA Page 12 to County Ordinance Chapter 822-4 - Inclusionary Housing, County Ordinance Chapter 822-2 - Density Bonus, and Government Code 65915 to ensure that two (2) of the approved units are affordable to and occupied by lower-income households, and one (1) of the approved units is affordable to and occupied by a very low-income household.

If deposits of prehistoric or historical archaeological materials are encountered during ground disturbance activities, all work within 50 feet of the discovery shall be redirected and a qualified archaeologist contacted to evaluate the finds and, if necessary, develop appropriate treatment measures in consultation with the County and other appropriate agencies. If the deposits are not eligible, avoidance is not necessary. If eligible, deposits will need to be avoided by impacts or such impacts must be mitigated. Upon completion of the archaeological assessment, a report should be prepared documenting the methods, results, and recommendations. The report should be submitted to the Northwest Information Center and appropriate Contra Costa County agencies. B. If human remains are encountered, work within 50 feet of the discovery shall be redirected and the County Coroner notified immediately. At the same time, an archaeologist shall be contacted to assess the situation. If the human remains are of a Native American origin, the Coroner must notify the Native American Heritage Commission within 24 hours of this identification. The Native American Heritage Commission will identify a Most Likely Descendant (MLD) to inspect the property and provide recommendations for the proper treatment of the remains and associated grave goods. Upon completion of the assessment by an archaeologist, the archaeologist should prepare a report documenting the methods and results and provide recommendations for the treatment of the human remains and any associated cultural materials, as appropriate and in coordination with the recommendations of the MLD. The report should be submitted to the Northwest Information Center and appropriate Contra Costa agencies.

Surrounding Land Uses and Setting: Surrounding Area: This area along Windhover Way is exclusively occupied by residential development. The adjacent parcels to the north and south host single family residences. To the east of the site is a 13- unit townhouse development. The two properties to the west both host duplexes. Approximately 316 feet northeast is a 12-unit apartment complex. Beyond the immediate neighborhood, along Pacheco Boulevard there are a variety of residential, commercial, and retail uses including multi-family housing, restaurants, schools, storage locations, gas stations, auto repair shops, and other retail services. Parcels within the City of Martinez jurisdiction are located approximately 1,100 feet to the east of the subject parcel. Subject Property: The subject lot is approximately 0.75-acres in size (approximately 32,820 square feet) rectangular shaped parcel (with the addition of a 52’ x 70’ strip which extends to the west and connects the parcel to Windhover Way as an access.) The parcel is located on the east side of Windhover Way, approximately 125 feet north of the Pacheco Boulevard and Windhover Way intersection in the in the Pacheco/Vine Hill area. The parcel is vacant and is largely covered with grass and dirt and has eight trees located around the perimeter of the parcel. There is existing curb, sidewalk, streetlights, and underground utilities along the frontage of Windhover Way. Public Works has reviewed the submittal and has indicated that the applicant will not be required to perform further widening or frontage improvements. The general topographic slope of the parcel trends downward from west to east. The elevation starts at 40 feet above mean sea level at Windhover Way and slopes down to 31 feet above mean sea level at the rear of the property. The site currently has access off of Windhover Way which will continue to remain as the access point. The site contains eight trees consisting of London Plane, Carolina Cherry Laurel, California Black Walnut, Glossy Privet, Olive and Siberian Elm. 238 3 10.

View Sanitary District 11. Have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code section 21080.3.1? If so, is there a plan for consultation that includes, for example, the determination of significance of impacts to tribal cultural resources, procedures regarding confidentiality, etc.? A Notice of Opportunity to Request Consultation was sent on May 24, 2023, in accordance with section 21080.3.1 of the California Resources Code to the Wilton Rancheria and Confederated Villages of Lisjan Nation, the two California Native American tribes that have requested notification of proposed projects. Pursuant to section 21080.3.1(d), there is a 30-day time period for the Confederated Villages of Lisjan and the Wilton Rancheria to either request or decline consultation in writing for this project. Staff did not receive a request for consultation in response. Therefore, consultation with Native American tribes has not occurred in relation to this project. Environmental Factors Potentially Affected Without mitigation, the environmental factors checked below would have been potentially affected by this project. Upon incorporation of the mitigation measures identified in the following pages it has been found that the project will not result in any impacts to the environment. Aesthetics Agriculture and Forestry Resources Air Quality Biological Resources Cultural Resources Energy Geology/Soils Greenhouse Gas Emissions Hazards & Hazardous Materials Hydrology/Water Quality Land Use/Planning Mineral Resources Noise Population/Housing Public Services Recreation Transportation Tribal Cultural Resources Utilities/Services Systems Wildfire Mandatory Findings of Significance Environmental Determination On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that, although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the 239 4 project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated" impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR, including revisions or mitigation measures that are imposed upon the proposed project. _____________________________ ____________________ Everett Louie Date Planner II Contra Costa County Department of Conservation & Development Everett Louie 7/11/2023 240 DRAFT ENVIRONMENTAL CHECKLIST 5 Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 1. AESTHETICS – Except as provided in Public Resources Code Section 21099, would the project: a) Have a substantial adverse effect on a scenic vista? b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic building within a state scenic highway? c) In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the site and its surroundings? (Public views are those that are experienced from publicly accessible vantage points.) 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? SUMMARY: a) Less Than Significant Impact: The Open Space Element of the County General Plan identifies major scenic ridges and waterways within the County as shown in Figure 9-1. The project site is located more than 3 miles to the east of the nearest scenic ridgeway. The subject property is not located near a major scenic resource and will therefore have a less than significant adverse effect on a scenic vista. b) Less Than Significant Impact: Figure 5-4 (Scenic Routes Plan) of the Contra Costa County Transportation and Circulation Element identifies the roadways which form the Countywide scenic routes plan. The project site is bounded by Pacheco Blvd to the south and Windhover Way to the west. The nearest scenic highway is Highway 4 which is approximately 1.30 miles to the south of the project site. Highway traffic is not visible from the site. Since the subject property is not visible from a state scenic highway and is void of any structures (the project site is vacant and covered in shrubs), the project would not substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway. c) Less Than Significant Impact: The vacant property site is located within the Multiple-Family Residential (M-29) zoning district. Generally speaking, the intent of the M-29 zoning district is to provide for residential infill development at a density which is supportive of the surrounding area. In general, the project has been designed pursuant to the guidelines for development within the M-29 zoning district. The project has been designed to be compatible with the existing residential development in the area, including orienting the main entrance towards the Windhover Way frontage. Surrounding uses include single-family residences to the north and south, a 13-unit townhouse development to the east and a 12-unit apartment complex to the northeast. The project has been reviewed for compliance with the M-29 zoning district 241 DRAFT 6 standards, which included the review of the preliminary landscape design that has been submitted with the application. The project proposes to enhance the scenic quality of the site, turning it from a vacant lot with overgrown vegetation to an urban use with landscaping. The final landscape plan must be reviewed by staff upon project approval and prior to applying for building and/or grading permits. Therefore, the project would not conflict with any applicable zoning and/or other regulations governing scenic quality. d) Less Than Significant Impact With Mitigation Incorporated: The project site is located in an urbanized area. However, the site itself is vacant and would introduce new lighting as part of the project design. As required by the Off-Street Parking ordinance, the proposed project will include the installation of four downward-oriented LED streetlight-style lights to be located near the carport to illuminate the parking areas and to allow for safe circulation around the subject property during times of low natural light. The applicant has submitted a preliminary lighting plan that details the location and type of proposed exterior lighting. The lighting plan indicates that the location of the lights will be minimally located near residences off-site. Additionally, the potential for light spillover is limited due to the proposed landscaping which includes trees, a new stone masonry fence and an existing wood fence. The following mitigation measure shall ensure that all outdoor lighting is directed downward and positioned away from adjacent properties and streets, reducing such impacts to a less than significant level. Potential Impact: Project lighting could spill off-site and result in a potentially significant adverse environmental impact due to substantial new light and glare on neighboring properties. Thus, the following mitigation measure would ensure such impacts from project lighting would have a less than significant impact on nighttime views. Mitigation Measure Aesthetics 1: Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, whichever occurs first, a lighting plan shall be submitted to the (CDD) for review and approval. The lighting plan shall provide the specifications of the proposed light post as shown on the approved plans. All outdoor lighting shall be directed down and screened away from adjacent properties and public/private right-of-way to prevent glare or excessive light spillover.

AGRICULTURAL AND FOREST RESOURCES – Would the project: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non- agricultural use? b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? c) Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g)? d) Result in the loss of forest land or conversion of forest land to non-forest use? e) Involve other changes in the existing environment, which due to their location or nature, could result in conversion of farmland, to non-agricultural use? SUMMARY: a-e) No Impact: The project site is located within the Multiple-Family Residential (M-29) zoning district. The parcel is within an “Urban and Built-Up Land” area as shown on the California Department of Conservation’s Contra Costa County Important Farmland 2018 map. Neither the subject property, nor those in the vicinity are zoned for agricultural use nor does the site contain farmland designated “Prime”, “Unique”, or of “Statewide Importance”. The site is not under a Williamson Act contract with the County. Additionally, the project site is not considered forest land as defined by California Public Resources Code Section 12220(g) or timberland as defined by California Public Resources Code Section 4526. Development of a vacant lot that is not being used for any agricultural use and turning it into a residential project would not involve substantial changes to the existing urban environment. Furthermore, the project site is located in an area of the County that is urbanized and contains uses which include residential, commercial and mixed use. Therefore, the project will have no impact on agricultural or forest resources, will not convert Prime Farmland, unique Farmland or Farmland of Statewide importance to a non-agricultural use, will not result in the conversion or loss of forest resources and will not contribute indirectly to the conversion of adjacent farmland.

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? SUMMARY: a) Less Than Significant Impact: Contra Costa County is within the San Francisco Bay air basin, which is regulated by the Bay Area Air Quality Management District (BAAQMD) pursuant to the Bay Area 2017 Clean Air Plan. The purpose of the Clean Air Plan is to bring the air basin into compliance with the requirements of Federal and State air quality standards and to protect the climate through the reduction of criteria pollutants and greenhouse gases. The CEQA Guidelines support lead agencies in analyzing air quality impacts. If, after analysis, the project’s air quality impacts are found to be below the significant thresholds, then the air quality impacts may be considered less than significant. The potential air quality impacts for this project were evaluated using the BAAQMD 2017 CEQA guidelines screening criteria. Pursuant to these guidelines, if a project does not exceed the screening criteria size it is expected to result in less than significant impacts to air quality. The operational criteria pollutant screening size for the land use type “Apartment, low-rise” is 240 dwelling units, and the construction-related screening size is 78 dwelling units. The proposed 24 dwelling unit apartment complex is below the residential screening criteria for the low-rise apartment complex for both operational (i.e., occupancy of the residential units) and construction-related pollutants. Furthermore, the screening criteria developed by BAAQMD generally represent new developments on greenfield sites. The proposed project is proximate to regional transit service and is considered an infill project in the otherwise developed, surrounding area of Martinez. The County’s Climate Action Plan (CAP) is designed to reduce local greenhouse gas (GHG) emissions while improving community health consistency with the BAAQMD’s guidance on preparing a qualified GHG reduction strategy and State assembly Bill (AB) 32 GHG reduction targets. To assist staff and developers with implementation of the GHG reduction strategy, the CAP includes a development checklist (Appendix E) with strategies for project consistency with the CAP. Such strategies include the installation of high-efficiency appliances, insulation, 244 DRAFT 9 electric vehicle (EV) charging stations, and locating new development within one half mile of a BART, Amtrak, or bus station. Staff will recommend conditions of approval to require verification by staff of the County Building Inspection (BID) and Community Development Division (CDD) of the project’s compliance with Appendix E standards prior to issuance of building permits. Therefore, the potential for the project to conflict with or obstruct implementation of BAAQMD’s Clean Air plan or the County’s Climate Action Plan is less than significant. b) Less Than Significant Impact: As discussed above, the proposed 24-unit apartment complex is less than the criteria pollutant screening size determined by the BAAQMD, and thus would not result in significant emissions of criteria air pollutants during the construction period or during project operation. In addition, by implementing the strategies of the County CAP to reduce GHG emissions, the proposed project would not cause a violation of any air quality standard and would not contribute substantially to any existing or projected air quality violation. Although the proposed project would contribute incrementally to the level of criteria air pollutants in the atmosphere, the project would have a less than significant impact on the level of any criteria pollutant. c) Less Than Significant Impact With Mitigation Incorporated: The project is not expected to cause any localized emissions that could expose sensitive receptors (e.g., nearby residences, schools) to unhealthy long-term air pollutant levels. Construction activities, however, would result in localized emissions of dust and diesel exhaust that could result in temporary impacts to nearby residences, schools, and businesses. Construction and grading activities would produce combustion emissions from various sources including heavy equipment engines, paving, and motor vehicles used by the construction workers. Dust would be generated during site clearing, grading, and construction activities, with the most dust occurring during grading activities. The amount of dust generated would be highly variable and would be dependent on the size of the area disturbed, amount of activity, soil conditions, and meteorological conditions. Although grading and construction activities would be temporary, such activities could have a potentially significant adverse environmental impact during project construction. Consequently, the applicant is required to implement the following mitigation measures, which the BAAQMD recommends to reduce construction dust and exhaust impacts to a less than significant impact. Potential Impact: Future grading and construction activities on the project site would result in localized emissions of dust, diesel exhaust, and combustion emissions that could result in potential, if temporary, air quality impacts to sensitive receptors (e.g., nearby residences, schools) from the project site during project construction. Mitigation Measure Air Quality 1: The following mitigations shall be included on all construction plans and implemented throughout the construction phase of the project: 1. All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day. 2. All haul trucks transporting soil, sand, or other loose material off-site shall be covered. 245 DRAFT 10 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. 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. Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations [CCR]). Clear signage shall be provided for construction workers at all access points. 7. All construction equipment shall be maintained and properly tuned in accordance with manufacturer’s specifications. All equipment shall be checked by a certified visible emissions evaluator. 8. The property owner or site contractor shall post a publicly visible sign with the telephone number and person to contact at the lead agency 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. 9. 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. 10. All contractors shall use equipment that meets the California Air Resources Board' s (CARB) most recent certification standard for off-road heavy duty diesel engines. Implementation of these mitigation measures would reduce the impact on the sensitive receptors during project construction to a less than significant level. d) Less Than Significant Impact With Mitigation Incorporated: The BAAQMD’s 2017 CEQA guidelines indicate that odor impacts can occur from two different situations: 1) siting a new odor source, or 2) siting a new sensitive receptor (e.g., residents). Although not absolute, screening level distances between sources and receptors are utilized by BAAQMD to identify potentially significant impacts from malodors. Depending on the type of land use, the identified screening distance is between one and two miles as shown on Table 3-3 of the CEQA Guidelines. These distances are to be used in conjunction with available complaint history. For example, any odor source with five or more confirmed complaints per year, averaged over three years, is considered to have a significant impact on receptors within the applicable screening distance. Examples of land uses which may potentially generate significant odors include wastewater treatment plants, landfills/composting stations, refineries, chemical plants, etc. The project is not expected to result in other emissions, such as objectionable odors, that would adversely affect a substantial number of people (objectionable odors are typically associated with agricultural or heavy industrial land uses such as refineries, chemical plants, landfills, sewage-treatment plants, etc.) during project operation. However, during construction and grading, diesel powered vehicles and equipment used on site could create localized odors. These odors would be temporary, but there could be a potentially significant adverse environmental impact during project construction due to the creation of objectionable odors. Consequently, the applicant is required to implement Mitigation Measure Air Quality 1 above. 246 DRAFT 11 Implementation of this mitigation would reduce the impact from the creation of objectionable odors to a less than significant level.

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 4. BIOLOGICAL RESOURCES – Would the project: a) 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 Game or U.S. Fish and Wildlife Service? b) 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 Game or U.S. Fish and Wildlife Service? c) 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? d) 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? e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? f) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? 247 DRAFT 12 SUMMARY: a) Less Than Significant Impact: The Conservation Element, Figure 8-1 indicates that the project site is not located in a significant ecological area and according to the California Fish and Wildlife Public Access Lands Map, the project site is not indicated to include an area of wildlife or ecological reserve. The location of the project site is surrounded by commercial and residential development and the site currently is vacant with weeds. The site lacks suitable habitat (there are no creeks, wetlands, or riparian habitats located on the subject parcel. Therefore, there will be a less than significant impact on any special status species. b) No Impact: According to the California Department of Fish and Wildlife (CDFW) Public Access Lands map, the project site is not located in or adjacent to an area identified as a wildlife or ecological reserve by the CDFW. According to the Significant Ecological Areas and Selected Locations of Protected Wildlife and Plant Species Areas map (Figure 8-1) of the County General Plan, the project site is not located in or adjacent to a significant ecological resource area. In addition, the property contains no perennial or intermittent streams, creeks or other riparian habitat – Vine Hill Creek is located approximately 900 feet southeast of the subject property. Therefore, the 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 U.S. Fish and Wildlife Service. c) No Impact: Wetlands are defined and identified under Section 404 of the Clean Water Act as “areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.” According to the U.S. Fish and Wildlife Service National Wetlands Inventory map, no wetlands are located at or adjacent to the project site. Therefore, no substantial adverse effects on federally protected wetlands are expected to occur as a result of this project. d) Less Than Significant Impact: The project site does not contain any creeks, wetlands, or riparian habitats located on the subject parcel. It is also not identified in Figure 8-1 of the Conservation Element as an area of significant ecological area or locations of protected wildlife and plant species. As previously mentioned, the project site is a vacant lot surrounded by multiple residential properties and commercial properties. The surrounding area has been disturbed and developed. Therefore, the proposed development is expected to have a less than significant impact on 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 nursery sites, based on existing site conditions and the surrounding land uses. e) Less Than Significant Impact: The project site has several trees that are located within the parcel boundaries. Because the lot is vacant, the trees are currently protected per Chapter 816-6, 248 DRAFT 13 Tree Protection and Preservation Ordinance. The project would remove four code protected trees and work within the dripline of three code protected trees for the construction of the 24- unit apartment building and other various improvements. The applicant is applying for a tree permit which is required prior to any work within the dripline of a code protected tree. The applicant will be required to comply with the conditions of approval which require a tree restitution bond and tree replanting plan. Therefore, as conditioned, the project will have a less than significant impact to tree resources in the County does not conflict with tree preservation policies for Contra Costa County. f) No Impact: The East Contra Costa County Habitat Conservation Plan/Natural Community Conservation Plan (ECCC HCP/NCCP) was adopted by the County in October of 2006. The purpose of this plan is to provide a framework to protect natural resources while streamlining the environmental permitting process for impacts to covered special status species within the rapidly expanding region of Eastern Contra Costa. The proposed project site is located outside of the HCP/NCCP urban development area and thus HCP ordinance no. 2007-53 does not apply to the project. Thus, the project would not conflict with any conservation plan.

CULTURAL RESOURCES – Would the project: a) Cause a substantial adverse change in the significance of a historical resource pursuant to §15064.5? b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? c) Disturb any human remains, including those interred outside of formal cemeteries? SUMMARY: a-c) Less Than Significant Impact with Mitigation Incorporated: The Vacant parcel is not a historical resource pursuant to Section 15065.5 of the CEQA Guidelines because: 249 DRAFT 14 1. It is not a resource listed in, or determined to be eligible by the State Historical Resources Commission, for listening in the California Register of Historical Resources; 2. It is not 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 section 5024.1(g) of the Public Resources Code; and 3. Has not been determined to be historically or culturally significant by a lead agency. In addition, the California Historical Resource Information System, Northwest Information Center (NWIC) has reviewed the project and determined that there is low possibility for the occurrence of unrecorded archeological resources at the site. Thus, no further study of archeological resources is recommended at this time. Additionally, figure 9-2 of the Open Space Element of the General Plan designates the site as “largely urbanized”, which generally means that there is a low probability for encountering archeological resources. The project site is vacant and as such, there are no existing buildings that would be more than 45 years old. The project consists of the construction of an apartment building. The construction work could include trenching, grading and other subsurface work. The proposed project was reviewed by the NWIC, Wilton Rancheria Cultural Preservation Department and Confederated Villages of Lisjan Nation who did not provide any comments of concern. While the project was reviewed by the NWIC and Tribes in the area, there is nevertheless a potential for previously unknown cultural resources to be uncovered during the construction phase of the project. Potential Impact: Although there is no evidence that there is any specific cultural resources known in in the project area, there is nevertheless a potential for previously unknown cultural resources to be uncovered during construction activities requiring excavation or earth movement. The following mitigation measure will ensure that in the event cultural resources are discovered, the proper actions are taken to reduce the adverse environmental impacts to cultural resources to a less than significant level. Mitigation Measure Cultural 1: The following measures shall be implemented during project- related ground disturbance and shall be included on all construction plans. Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the applicant shall provide evidence that the measures and requirements listed below are included on the construction plans. A. All construction personnel, including operators of equipment involved in grading, or trenching activities will be advised of the need to immediately stop work if they observe any indications of the presence of an unanticipated cultural resource discovery (e.g., wood, stone, foundations, and other structural remains; debris-filled wells or privies; deposits of wood, glass, ceramics). If deposits of prehistoric or historical archaeological materials are encountered during ground disturbance activities, all work within 50 feet of the discovery shall be redirected and a qualified archaeologist contacted to evaluate the finds and, if 250 DRAFT 15 necessary, develop appropriate treatment measures in consultation with the County and other appropriate agencies. If the deposits are not eligible, avoidance is not necessary. If eligible, deposits will need to be avoided by impacts or such impacts must be mitigated. Upon completion of the archaeological assessment, a report should be prepared documenting the methods, results, and recommendations. The report should be submitted to the Northwest Information Center and appropriate Contra Costa County agencies. B. If human remains are encountered, work within 50 feet of the discovery shall be redirected and the County Coroner notified immediately. At the same time, an archaeologist shall be contacted to assess the situation. If the human remains are of a Native American origin, the Coroner must notify the Native American Heritage Commission within 24 hours of this identification. The Native American Heritage Commission will identify a Most Likely Descendant (MLD) to inspect the property and provide recommendations for the proper treatment of the remains and associated grave goods. Upon completion of the assessment by an archaeologist, the archaeologist should prepare a report documenting the methods and results and provide recommendations for the treatment of the human remains and any associated cultural materials, as appropriate and in coordination with the recommendations of the MLD. The report should be submitted to the Northwest Information Center and appropriate Contra Costa agencies.

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 6. ENERGY – 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? SUMMARY: 251 DRAFT 16 a) Less Than Significant Impact: In December 2015, a Climate Action Plan (CAP) was adopted by the Contra Costa County Board of Supervisors in order to identify and achieve a reduction in greenhouse gas (GHG) emissions by the year 2020 as mandated by the State under AB32. The design and operation strategies set forth in the CAP for reducing GHG emissions include measures such as installing energy efficient appliances that would also reduce the project’s consumption of energy resources during operation. The residential project will be required to comply with all California Code Title 24 (CalGreen) building energy efficiency standards for an apartment residential building that are in effect at the time that building permit applications are submitted, including any standards regarding the provision of solar energy. If approved, the project will be reviewed under all current energy standards as part of the plan check process. During the plan check process, the proposed development would be subject to the 2022 California Building Standards Code which would include compliance with the energy conservation standards in the Energy Code Section and CalGreen Code Section of the 2022 California Building Standards Code. In addition, the project must also comply with the County’s Water Efficient Landscape Ordinance, which promotes efficient water use. Compliance with all applicable regulations will ensure this development will not have a significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy. During construction, the project may require temporary electrical power. The General Contractor would be required to apply for a temporary power permit from the County and to comply with all applicable building standards for a temporary power connection. Therefore, the impact of construction or operation on electrical energy resources is anticipated to be less than significant. b) Less Than Significant Impact: As mentioned in subsection-a above, the residential project will be required to comply with all California Code Title 24 (CalGreen) building energy efficiency standards for an apartment residential building that are in effect at the time that building permit applications are submitted, including any standards regarding the provision of solar energy. In addition, the design and operation strategies set forth in Table E.1 Standards for CAP Consistency – New Development (Appendix E of the County’s CAP) include measures such as installing energy efficient appliances that would also reduce the project’s consumption of energy resources. Therefore, the project will not conflict with a state or local plan for renewable energy or energy efficiency.

GEOLOGY AND SOILS – Would the 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? SUMMARY: a) i) Less Than Significant Impact: The California Division of Mines and Geology’s Special Publication 42 indicates that the State Geologist is required to delineate “Earthquake Fault Zones” (EFZs) along known active faults in California. The project site is not mapped within an EFZ, nor within an Alquist-Priolo Special Studies Zone. The nearest fault considered active by the CGS is the Concord fault, which passes more than 10.000 feet east of the site. Because the site is not within an official Earthquake Fault Zone, the risk of fault rupture is generally regarded as very low. ii) Less Than Significant Impact: The U.S. Geological Survey (2016) indicates that there is a 72 percent chance of at least one magnitude 6.7 or greater earthquake striking the San Francisco Bay region between 2014 and 2043. With that, the County General Plan Safety Element 253 DRAFT 18 identifies areas that are more or less susceptible to seismic damage as shown in Figure 10-4 Estimated seismic Ground Response. According to Figure 10-4 of the Safety Element, the property is located on Hard Bedrock which has the lowest damage susceptibility. The risk of structural damage from ground shaking is regulated by the building code and the County Grading Ordinance. Codes are intended to keep earthquake risks to an acceptable minimum, and they assume that the ground is stable. Ground failure can result in greater damage. Nevertheless, compliance with the operative provisions of the California Building Code (CBC) along with (i) compliance with the County Grading Ordinance (ii) conservative design and (iii) quality construction are the best means of controlling the life loss and damage potential of earthquakes. Current CBC (2022) requires the use of seismic parameters in the design of all structures requiring building permits. These parameters are based on soil profile types and proximity of faults deemed capable of generating strong/violent earthquake shaking. Design level geotechnical reports routinely provide CBC seismic design parameters, and upon implementation of the mitigations below, adverse effects due to strong seismic ground shaking would be reduced to a less than significant level. iii) Less Than Significant Impact With Mitigation Incorporated: The Safety Element (Figure 10-5 Estimated Liquefaction Potential) of the County General Plan divides lands within the County into three liquefaction potential categories: generally high, generally moderate to low, and generally low. It is used as a “screening criteria” during the processing of land development applications, on a project-by-project basis. By intent, the map is conservative on the side of safety. The project site is entirely or chiefly in an area classified as generally high liquefaction potential. As a result, the project applicant submitted a Geology study that was peer reviewed by the County geologist, Darwin Myers Associate (DMA). The Geology report prepared by GEC Consultants confirmed that the soils are known to be expansive and corrosive and identified undocumented fill on site as an issue of drainage. The County Peer Review Geologist (DMA) reviewed the report by GEC Consultants and concluded that the report of GEC Consultants sufficient to define the geotechnical hazards and to identify mitigation measures. DMA recommends that an updated report be provided prior to issuance of grading or building permits. The focus of the updated report shall be to address the following potential hazards, expansive soils, corrosive soils, siting and design of any required bio-retention facilities and/or other measures that may be recommended to achieve compliance with the clean water requirements of the RWQCB, possible presence of existing undocumented fills and provide seismic parameters based on the California Building Code. Thus, the applicant is required to implement the following mitigation measures: Potential Impact: The project site is within an area where soils are known to be expansive and may be corrosive. Additionally, the geotechnical report prepared by GEC Consultants identified the presence of undocumented fill on the site. Accordingly, staff recommends that the following mitigation measures be incorporated as part of the project to reduce the potential hazards resulting from corrosive soils and other onsite conditions to a less than significant level. 254 DRAFT 19 Mitigation Measure Geology 1: Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the project proponent shall submit a geotechnical report update with the geotechnical review fee in the amount of $3,000, referencing the proposed grading, drainage and foundation plans and providing specific criteria and standards for site grading, drainage and foundation design based on adequate subsurface data, laboratory testing of samples and engineering analysis. The scope of the geotechnical investigation shall address the following potential hazards: (i) expansive soils, (ii) corrosive soils, (iii) siting and design of any required bio-retention facilities and/or other measures that may be recommended to achieve compliance with the clean water requirements of the RWQCB, (iv) possible presence of existing undocumented fills and effective measures to control/ mitigate the settlement hazard, (v) provide seismic parameters based on the adopted California Building Code at the time that a residential building permit is requested. Mitigation Measure Geology 2: Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the geotechnical report update required by Geology 1, above, shall be subject to review by the County’s peer review geologist, and review/approval of the CDD. Improvement, grading and building plans shall carry out the recommendations of the approved report. iv) Less Than Significant Impact: In 1975, the USGS issued photo-interpretation maps of landslides and other surficial deposits in Contra Costa County (that mapping is presented on Page 10-6 in the Safety Element of the County’s General Plan). According to this map, which was prepared by an experienced USGS geologist, the project site is in an area that is not known to have landslides. The County GIS Accela tool also does not identify the site as an area with the possibility of having a landslide. Therefore, it can be concluded that there is a less than significant impact for potential of landslides for this site. b) Less Than Significant Impact: Any areas that are disturbed during construction of the project would be covered by the proposed improvements or landscaping. Since all areas of the property that will be disturbed will be covered by new structures, pervious and impervious surfaces, or landscaping, the potential for soil erosion or loss of topsoil is less than significant. Additionally, a routine provision for grading permits in Contra Costa County is a requirement for submittal of an erosion control plan. This plan is subject to technical review by inspectors of the County Grading Section. Normally there are refinements to erosion control plans as the winter rainy season approaches. Additional details are included in the refined erosion control plan, including such items as provisions for (a) storage of extra erosion control materials on site and (b) monitoring of the performance of disturbed areas on the site during/immediately following significant rainstorms. If erosion control facilities are damaged or failing to perform as intended, the erosion control measures being implemented on the site are refined to correct the deficiency. Implementation of an erosion control plan would further ensure that the project results in less than significant impacts due to erosion or the loss of topsoil. c) Less Than Significant Impact With Mitigation Incorporated: The geotechnical report prepared by GEC Consultants confirmed that the project site is within an area where the soils are known to be expansive and may be corrosive. Additionally, the report confirmed the presence of 255 DRAFT 20 undocumented fill on the site and they identified drainage as a concern. GEC recommended that the drainage should be carefully controlled in the vicinity of the proposed structures and that the undocumented fill must be over-excavated and either (i) incorporated into engineered fill or (ii) if the existing fill contains materials unsuitable for use in an engineered fill, that fill material shall be removed from the site and taken to a suitable facility for disposal. The County’s Peer Review Geologist is concerned that the report was not adequate for the issuance of construction permits without a report update. Potential Impact: The project contains soils that are known to be expansive and may be corrosive. With the addition of undocumented fill, there is potentially significant impact for the project to be located on unstable soil that is not suitable for supporting the proposed improvements. Accordingly, staff recommends that mitigation measures be incorporated as part of the project to reduce the potential hazards resulting from undocumented fill and to perform corrosion potential testing of the graded building pad. Mitigation Measure Geology 3: Following rough grading (but prior to commencement of foundation-related work) the project geotechnical engineer shall perform corrosion potential testing of the graded building pad to determine if special precautions shall be required to avoid damage to improvements that are in contact with the ground (concrete or steel). Mitigation Measure Geology 4: The geotechnical report required by Geology 1 routinely includes recommended geotechnical observation and testing services during construction. These services are essential to the success of the project. They allow the geotechnical engineer to (i) ensure geotechnical recommendations for the 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 BID approval), based on exposed conditions. The monitoring shall commence during clearing, and extend through grading, including testing services during placement of engineered fill, installation of recommended drainage facilities, and foundation related work. A hard 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 during grading, installation of drainage improvements. Similarly, a hard hold shall be placed on the final building inspection for the apartment building, pending submittal of a letter-report from the geotechnical engineer documenting the monitoring services associated with implementation of foundation-related geotechnical recommendations. The geotechnical monitoring shall include pier hole drilling/ foundation preparation work/ installation of drainage improvements (e.g. collection of roof gutter runoff in a closed conduit and conveying it to a suitable discharge point; and possibly installation of a subdrain system around the perimeter of the foundation to control moisture beneath the foundation). 256 DRAFT 21 d) Less Than Significant Impact With Mitigation Incorporated: The soil series that occurs at the site is known to be expansive and may be corrosive. Expansive soils expand when water is added and shrink when they dry out. This continuous change in soil volume can cause structures to move unevenly and crack. Corrosive soils tend to damage concrete and/or uncoated steel that is in contact with the ground. Geotechnical design criteria are needed to avoid/ minimize damage from these adverse soil conditions. A first step is to test the soils to confirm / modify the Soil Survey’s preliminary assessment. In the case of corrosion potential, the soil testing can determine if the soils are corrosive to either steel; or concrete; or to both steel and concrete. The results of that testing can serve to alert the developer and their development consultants (e.g., underground contractor, foundation contractor) of this hazard. The underground contactors can either consider the testing performed to be adequate and act on the results of testing; or they can perform supplemental testing to provide a more complete assessment of this hazard. Potential Impact: As discussed in Section 6(a)(iii) above, the available information indicates a significant risk of damage to structures / improvements due to these adverse soil conditions. Consequently, the applicant is required to implement the following mitigation measure. Mitigation Measure Geology 5: 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, unless additional grading is reviewed and specifically approved by the Building Inspection Division. e) No Impact: The subject property is within an area served by the Mt. View Sanitary District. The proposed development will be connected to the existing public sewer service. The Sanitary District has reviewed the project and has indicated that they would review the sewer improvement plans. There will be no septic system within the project. f) Less Than Significant Impact With Mitigation Incorporated: There are no known paleontological resources located at the project site nor have any unique geological features been identified. Nevertheless, there is always the potential for ground disturbing activity to reveal previously undocumented features. Implementing the mitigation below ensures the project will not significantly impact any such resource that may be uncovered by construction activity at the project site. Potential Impact: Ground disturbance during the project’s construction phase has the potential for disturbing previously unknown unique paleontological resources. In addition to the mitigation measures for Cultural Resources, the following mitigation measures will ensure that in the event unique paleontological resources are discovered, the proper actions are taken to reduce the adverse environmental impacts to unique paleontological resources to a less than significant level. Mitigation Measure Geology 6: Should unique paleontological materials be uncovered during grading, trenching, or other on-site excavation(s), all earthwork within 30 yards of the materials shall be stopped until the Community Development Division (CDD) has been notified, and a 257 DRAFT 22 qualified paleontologist contacted and retained to evaluate the significance of the find, and, if deemed necessary, suggest appropriate mitigation(s).

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 8. GREENHOUSE GAS EMISSIONS – Would the project: a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases? SUMMARY: a) Less Than Significant Impact: As discussed in the Air Quality section of this study, the Bay Area Air Quality Management District (BAAQMD) adopted the Bay Area 2017 Clean Air Plan that, in addition to various criteria air pollutants, addresses GHG emissions at a regional scale. The project includes a new 24-unit apartment building. The screening criteria are not thresholds of significance but were developed to provide a conservative indication of whether a proposed project could result in potentially significant air quality impacts. Pursuant to these guidelines, the potential for apartment style buildings would be 78 low-rise apartment dwellings. The project is much lower than the threshold as it proposes 24-units. While the project would generate some GHG emissions, the project’s global climate change is less than “cumulatively considerable’ because the project does not exceed applicable screening criteria, as described 258 DRAFT 23 above. Thus, it can be assumed that the project will have a less than significant impact on the environment regarding greenhouse gas emissions. b) Less Than Significant Impact: Within the 2017 Clean Air Plan is an ambitious GHG reduction target to reduce Bay Area GHG emissions to 80% below 1990 levels by the year 2050. The 2017 control strategy includes all feasible measures to reduce emissions of ozone precursors – reactive organic gases (ROG) and nitrogen oxides (NOx) – and reduce transport of ozone and its precursors to neighboring air basins. In addition, the plan builds upon and enhances BAAQMD’s efforts to reduce emissions of fine particulate matter and toxic air contaminants. BAAQMD’s approach to developing a threshold of significance for GHG emissions is to identify emissions level for which a project would not be expected to substantially conflict with existing California legislation adopted to reduce statewide GHG emissions. For land use development projects, the threshold is 1,100 metric tons per year (MT/yr) of CO2e. If a project would generate GHG levels above the threshold, it would be considered to contribute substantially to a cumulative impact and would be considered significant. The emissions generated as a result of the operational activities of the proposed 24-unit apartment complex will be far less than the significance threshold and will not result in significant levels of GHG that will conflict with any applicable plan, policy, or regulation pertaining to the reduction of GHG. There may be some increase in greenhouse gases as a result of the project, but they would be considered less than significant due to the temporary nature of the construction phase of the project as the project will be required to incorporate energy efficiency measures from the current Title 24 Building Energy Efficiency Standards Code and comply with the CalGreen / Construction & Demolition (C&D) Debris Recovery Program.

HAZARDS AND HAZARDOUS MATERIALS – Would the 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? d) 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 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 in 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? SUMMARY: a-b) Less Than Significant Impact: The proposed project consists of constructing a new 24-unit apartment complex. The proposed improvements and overall project site will be utilized for residential-related improvements and activities. Although small quantities of commercially available hazardous materials may be used for household or common-area cleaning or for landscape maintenance, these materials would not be used in sufficient quantities to pose a threat to human or environmental health. The use of fuels and lubricants, paints, and other construction materials would occur during the construction phase of the project. However, the use and handling of hazardous materials during construction would occur in accordance with applicable federal, state, and local laws, including California Occupational Health and Safety Administration (Cal/OSHA) requirements. With compliance with existing regulations, the project would result in a less than significant impact from construction activities. 260 DRAFT 25 Therefore, the potential for impacts associated with handling, storing, and dispensing of hazardous materials, or through reasonably foreseeable upset and accident conditions involving the likely release of hazardous materials into the environment from project construction or operation would be less than significant. Staff utilized EnviroStor from the Department of Toxic Substances Control’s data system and the tracking system determined that the site is not a site of hazardous waste. No evidence reviewed by staff suggests that the project would be located on a site with hazardous materials pursuant to Government Code Section 65962.5. Therefore, a less than significant impact is expected. c) Less Than Significant Impact: The Las Juntas Elementary School is located approximately 970 feet east while Morello Park Elementary School is located approximately 2684 feet south of the project site. However, due to the proposed use of the building (24-unit apartment), impacts on either school from hazardous substances emitting from the project site, post construction, would be less than significant. No evidence reviewed by staff suggests that the project would include foreseeable conditions involving the likely release of hazardous materials into the environment. The use of construction-related fuels and lubricants, paints, and other construction materials, during the construction period, would occur in accordance with applicable federal, state, and local laws, including California Occupational Health and Safety Administration (Cal/OSHA) requirements. Therefore, the potential impacts from the project to emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste, is considered to be less than significant. d) No Impact: The California Environmental Protection Agency maintains an updated list of Hazardous Waste and Substance Sites (Cortese List). The subject property is not listed on the Cortese List and is not categorized as a hazardous materials site. Therefore, the project will have no impact in this respect. e) No Impact: The project is not located within the vicinity of any public airport or public use airport and will not conflict with an airport land use plan. The nearest airport facility to the project site is the Buchanan Field airport, which is approximately 2 miles southeast of the project site. Thus, the proposed project would not present any safety hazard to airports or excessive noise for people residing or working in the project area. f) Less Than Significant Impact: The subject site fronts Windhover Way, which connects to Pacheco Boulevard, both are County maintained roads. Windhover Way along the project frontage is approximately 36-foot-wide street within a 56-foot right-of-way. There are existing curbs, sidewalk, streetlights, and underground utilities along the frontage. No further widening or frontage improvements are necessary with this development. The project will build a driveway that will connect to Windhover Way from the interior parking lot. The proposed project will not impact any existing communication/utility structures such as power poles or telecommunications towers which may be necessary for an existing emergency response or evacuation plan. Although project construction would primarily occur onsite, the required water main extensions may require temporary road closures or reduced lanes. Additionally, in the event that the alternative drainage plan would be necessary, extension of a new storm drain 261 DRAFT 26 pipe may require temporary or partial road closures. The nature and duration of those road closures would be subject to review by the County Public Works Department for compliance with applicable transportation regulations and require issuance of an encroachment permit. It should also be noted that the project was referred to the Contra Costa County Fire Protection District requesting comments. In a returned letter dated November 15, 2021, the Fire Protection District is requiring the applicant submit construction plans for review. All construction plans will be subject to the review of the Contra Costa County Fire Protection District for consistency with applicable Fire Code that is in effect at the time when the application for a building permit is submitted. Therefore, the routing review of construction plans will ensure that final construction plans will not result in a condition with inadequate emergency vehicle access. Accordingly, the project would have a less than significant impact on emergency response and emergency evacuation plans. g) Less Than Significant Impact: The project site is characterized as “urban unzoned” on the California Department of Forestry and Fire Protection’s Fire Hazard Severity Zone Map for local responsibility areas and thus, would not be considered to have a high hazard risk due to wildfires. The nearest High Fire Zone in Local Responsibility Area is over 2,000 feet north of the project site while the nearest High Fire Zone in State Responsibility Area is over 2 miles west. The project site is in a developed area within the service area of the Contra Costa County Fire Protection District (CCCFPD). Development projects are generally referred to the Fire District for review and comment to ensure that the proposal does not conflict with applicable fire codes. There was no indication from the CCCFPD review of the project that the proposed development poses a significant fire risk. Based on their review, the project proponent will be required to provide construction plans to the fire district for review and approval. The plans shall meet the 2022 California Building Code, 2022 California Residential Code and the applicable California Fire Code. Therefore, there is a less than significant impact of indirect risk of exposing people to loss, injury, or death involving wildland fire.

HYDROLOGY AND WATER QUALITY – Would the 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 project may impede sustainable groundwater management of the basin? c) Substantially alter the existing drainage pattern of 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? 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? SUMMARY: a) Less Than Significant Impact: The proposed development is residential in nature, and will not consist of any manufacturing, processing, industrial, or other commercial activities which would generate by-products or waste that would pose a significant risk for impacting water quality or waste discharge requirements within the County. The project site is located within the service of the MT. View Sanitary District service area and will have access to public sewage disposal services. A Stormwater Control Plan (SWCP) is required for applications that will create and/or redevelop impervious surface area exceeding 10,000 square feet (5,000 square feet for projects that include parking lots, restaurants, automotive service facilities and gas stations), 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 263 DRAFT 28 (NPDES) Permit. The proposed development is residential in nature, and will not consist of any manufacturing, processing, industrial, or other commercial activities which would generate by-products or waste that would pose a significant risk for impacting water quality or waste discharge requirements within the County. The project includes approximately 23,790 square feet of impervious surface (including the building and parking area), which is above the threshold for requiring submittal of a SWCP. The applicant submitted a preliminary Stormwater Control Plan (SWCP) for the proposed stormwater management facilities and controls as required by the County’s Stormwater Management and Discharge Control Ordinance. The SWCP submitted by the applicant has been deemed “preliminarily complete” by the County’s Public Works Department for the purposes of this phase of project review. Subsequent revisions and a final SWCP will be required as the project proceeds through the design and construction process. The project is not expected to violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality because the applicant shall be required to 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 II). Compliance shall include developing long-term best management practices (BMPs) for the reduction or elimination of stormwater pollutants. The project design shall incorporate, wherever feasible, long-term BMPs in accordance with the Contra Costa Clean Water Program for the site's stormwater drainage. b) Less Than Significant Impact: The project site is within the Contra Costa Water District (CCWD) service area. Since the project proposes to utilize a public water supply, no groundwater wells would be required. Pursuant to a letter from CCWD, the proposed development will require a fire service, a domestic service and an irrigation service for the landscaping. CCWD recommended that the applicant submit plans to the water district for review and approval. The project also plans to install up to four bioretention areas that would help facilitate groundwater recharge and help offset the increased impervious surface area on the project site. Therefore, there is less than significant potential for the project to substantially decrease groundwater supplies, interfere with groundwater recharge, or impede sustainable groundwater management of the basin. c) i, ii, iii Less Than Significant Impact: 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. A preliminary stormwater control plan was prepared by CALICHI Design Group which indicated that the storm drain improvements for this development would direct drainage to the frontage of Windhover Way. The applicant will construct retaining walls along the east and south property lines to eliminate 264 DRAFT 29 the current surface discharge of water to adjacent properties. The Contra Costa County Public Works Department has reviewed the drainage pattern at 98 Windhover Way and found no evidence that the property currently drains onto the vacant parcel at APN 380-220-066. The County elevation date contours imply that stormwater should natural drain southeast from 98 Winhover Way, avoiding the proposed project parcel. Additionally, the site proposed drainage upgrades to prevent any off-site drainage. The property slopes from the northwest corner to the southeast corner, away and considerably below street grade. The applicant proposes to install a bioretention facility onsite which discharges to an existing 18” storm drain in Windhover Way, effectively diverting the onsite flows. The applicant has requested an exception to Division 914 of the County Ordinance per section 92- 6.002 of the County Ordinance Code. Further, analysis of the project by the Contra Costa County Public Works Department determined that the applicant shall be permitted an exception from the collect and convey requirements of the County Ordinance Code and will be allowed to discharge to an existing storm drain provided that the applicant submit a drainage report to verify the adequacy of the downstream drainage system. The applicant will be required to submit a report verifying the adequacy of the stormwater facility or natural watercourse to which the stormwater shall be directed (and to ensure that the system is adequate). d) No Impact: Seiche, tsunami, and mudflow events are generally associated with large bodies or large flows of water. The project site is not located within a 100-year or 500-year flood plain as designated on the Federal Emergency Management Agency Flood Insurance Rate Map. According to the Safety Element of the County General Plan, the project site is not located in a hazard zone for mudflows. A seiche is a water wave in a standing body of water such as a large lake or reservoir that is caused by an earthquake, a major landslide, or strong winds. This hazard does not exist within the Martinez area as there are no large lakes or reservoirs in the area. As such, there would be no risk of pollutants being released from the site due to inundation through flooding, tsunamis, mudflows, or seiche, therefore, there would be no impact in this regard. e) Less Than Significant Impact: The project is not expected to violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or ground water quality because the applicant shall be required to 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 II). Compliance shall include developing long-term best management practices (BMPs) for the reduction or elimination of stormwater pollutants. The project design shall incorporate, wherever feasible, long term BMPs in accordance with the Contra Costa Clean Water Program for the site's stormwater drainage. Therefore, the project would have a less than significant impact on the implementation of an adopted water quality control plan or sustainable groundwater management plan.

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 11. LAND USE AND PLANNING – 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? SUMMARY: a) No Impact: The subject property is currently vacant lot within a developed, urban area of the Martinez area in unincorporated Contra Costa County. Existing land uses in the vicinity primary consists of single-family residential development and related uses such as churches, schools, convenience stores, apartment buildings and townhouses. The project site is approximately 0.75 acres in area and is not large enough to constitute an independent established “community” within its boundaries. Furthermore, the proposed project does not consist of a new roadway, wall structure, or other improvements that would physically divide, or impede or disrupt the manner in which people enter and exit the Martinez area and the Windhover/Pacheco area in general. Due to the mixed-use zoning of the project vicinity, the proposed development would not divide an established community. b) Less Than Significant Impact: The applicant is requesting approval of a of a Development Plan to construct an approximately 22,247-square-foot in size, 24-unit apartment building, construct a covered carport for 16 parking spaces, and to install of associated improvements (e.g., pavement, utilities, stormwater conveyance) on a vacant property. The project includes a Tree Permit for the removal of four code protected trees within the dripline of three code protected trees. The project includes two units for low-income households and one unit for very low- income households and a request for a Density Bonus of two units for a total of 24 units. Land Use Element The project site is located within the Multiple-Family Residential High Density (MH) General Plan Land Use designation. Generally speaking, the intent of the MH designation is to allow for 266 DRAFT 31 residential uses such as apartments, condominiums, town houses and auxiliary uses such as churches. The proposed project would construct a 24-unit apartment complex on a parcel intended for High Density residential uses. The proposed apartment development will be residential in nature, and as a result will be compatible with other residential uses that surround the site. Within this designation, the General Plan allows for 22.0 to 29.9 multiple-family units per net acre. Thus, as proposed the multi-family project is consistent with the Contra Costa County General Plan development guidelines for the MH land use designation. General Plan Policies for the Vine Hill/Pacheco Boulevard Area The project site is located within the Vine Hill/Pacheco Boulevard area. As such, the following general plan policies for this area are applicable to the project and the project is consistent with these policies. • Policy 3-105: The scenic assets and unstable slopes of the Vine Hill Ridge are to be protected for open space/agricultural use. The proposed project is not located on or near Vine Hill Ridge. Therefore, the project will not impact the open space/agricultural use of that area. • Policy 3-106: The residential neighborhood east of I-680 shall be buffered from the industrial/landfill-related uses. The project parcel is located west of I-680, therefore this policy does not apply to the project. • Policy 3-107: Approximately 40 acres of land south of the Burlington Northern Santa Fe tracks, between Morello and Pacheco, is designated Agricultural Lands, to encourage the continued operation of the Viano family vineyards and winery. The project parcel is not located within the land designated in the policy. The project parcel is over 1,500 feet northeast of the Viano family vineyards and winery. Therefore, the project will not conflict with this policy. Housing Element A component of preparing the County’s Housing Element for the General Plan is the identification of vacant and underutilized suits 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). In order to assess whether this residential development application is subject to requirements of California Government Code section 65863, staff reviewed the site inventory for the adopted 2014 Housing Element and determined that Assessor’s Parcel Number 380-220-066 is not among the parcels listed in the inventory of residential sites which were relied upon to meet the 267 DRAFT 32 County’s share of regional housing needs. Nevertheless, the project includes a total of 24 residential units. The project includes one-bedroom and two-bedroom units. These unit types will increase housing opportunities for different size households for different income categories. As previously stated, this project maximizes the housing density and development of the site and includes a density bonus of nine percent above the base unit density for the site. Therefore, the project will contribute towards the regional housing need for the County and provide needed housing units for the region. Zoning The subject property is within the M-29 Multiple Family Residential (M-29) Zoning district. County Code 84-26.402 – Uses – Permitted (3) states that Multiple family buildings, but not including motels or hotels, is permitted use. Therefore, the proposed project is a permitted use within the M-29 Zoning. With the included variances and concessions pursuant to Government Code Section 65915(e), the application is consistent with the districts’ development standards and the County Zoning Ordinance. The district’s zoning development standards dictate allowable development in the area. The project would require two variances from these standards, building height and reduced driveway aisle width and would utilize the Density Bonus Request to request a concession to reduce the open space requirement and a reduction for parking stall size, parking setback and total number of covered parking spaces. The variance request for increased building height and parking aisle width would be consistent with the intent of the zoning district and are necessary given the project site’s constraints. The variance for building height is a result of the necessary lot padding that is required for drainage to be directed to Windhover Way as the lot is lower by almost 6 feet at the rear of the property. The added fill raises the height of the building from 34’ to 38’-6”. The reduced parking isle widths allows for the project allow the project to have more parking spaces and an aisle for vehicles to navigate. The reduction in parking aisle space allows for more maneuverability and to accommodate additional parking spaces. With the project proposing to meet the minimum landscape coverage, the driveway aisle space had to be reduced to accommodate this feature. With just a small reduction in the driveway aisle width, the project can provide more parking spaces and landscape area. The project requests the following concessions, reduction in development standards, and exception: • A density bonus concession to reduce the Open Space requirement from 25% to 20.5%; • A reduction in development standards pursuant to Government Code 65915(p) for parking ratios; • A reduction in development standards pursuant to Government Code 65915(e) for reduced parking stall size, parking setbacks, and total number of covered parking spaces; • An exception to Division 914, Collect and Convey requirements. 268 DRAFT 33 The project is subject to Chapter 822-4, the Inclusionary Housing Ordinance, and the applicant is required to constrict 3.3 inclusionary units. The applicant has submitted an Inclusionary Housing Plan, which proposes to construct and rent three inclusionary units. Two units will be available to “lower-income households,” and one will be available to a “very low-income household.” Although the project consists of requests for variances to allow for an increased maximum height and driveway aisle width, reduction in development standards to allow for reduced parking stall size, parking setbacks and total number of covered parking spaces, concessions to reduce the Open Space requirement, and an exception to the collect and convey drainage requirements the project substantially conforms to the design guidelines and General Plan Policies for the Martinez area as well as other General Plan policies and goals for unincorporated Contra Costa County. Therefore, the project has a less than significant potential for conflicting with any applicable land use, policy, General Plan, Specific Plan, or zoning ordinance adopted for the purpose of avoiding or mitigating an environmental effect.

MINERAL RESOURCES – Would the project: a) Result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state? b) Result in the loss of availability of a locally- important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? SUMMARY: a-b) No Impact: Pursuant to Figure 8-4 (Mineral Resource Areas) of the County General Plan Conservation Element, the project site is not located within any area of the County identified as a significant mineral resource area. No known mineral resources have been identified in the project vicinity, and there is no reason to believe that they exist at the project site. Therefore, the project would not result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state and would not impact any mineral resource recovery site.

NOISE – Would the project: a) 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? b) Generation of excessive groundborne vibration or groundborne noise levels? c) 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? SUMMARY: a) Less Than Significant Impact With Mitigation Incorporated: The subject property fronts Windhover Way. The project site is within an area of Martinez that is generally used for mixed use including residential, commercial and light industrial. Figure 11-5C of the Noise Element of the Contra Costa County General Plan (2005-2020, identifies that the subject property is within an area of the County where 2005 DNL and CNEL Noise levels range above 60 decibels (dB). Although Contra Costa County’s threshold for residential uses is a DNL of 60dB as shown on Figure 11-6 (Land Use Compatibility for Community Noise Environments) of the County General Plan’s Noise Element, the County requires new multiple-family residential projects to have an interior standard of 45dBA DNL or less. To evaluate the noise levels of the proposed project, a noise study was prepared by Michael Thill of Illingworth & Rodkin, Inc. A noise monitoring survey was conducted to quantify the existing noise environment at the site between Wednesday, April 27, 2022 and Friday, April 29, 2022. The noise monitoring survey included two long-term noise measurements (LT-1 and LT-2) and three short-term noise measurements (ST-1, ST-2, and ST-3), as showing in Figure 1. All noise measurements were conducted with Larson Davis Laboratories Model LxT1 Sound Level Meters fitted with ½-inch pre-polarized condenser microphones and windscreens. The meters were calibrated with a Larson Davis Model CAL200 precision acoustic calibrator prior to and following the measurement survey. The internal clocks of the sound level meters were synchronized to ensure 270 DRAFT 35 both identical sound level response and simultaneous operation. As shown in Figure 1 below, noise level measurements were taken in five areas within the subject property to determine the difference in noise levels. The surveys were conducted at elevated positions (e.g., 12 feet above the existing grade) to simulate noise exposure levels at the ground floor and second floors of the proposed apartment building. According to the study, traffic along Pacheco Boulevard was the predominant noise source at these locations. Table 3 summarizes the noise measurement results. The future noise environment at the project site will continue to result primarily from vehicle traffic along Pacheco Boulevard. An increase in traffic volumes along Pacheco Boulevard would correlate to an increase in noise levels at the project site. The Martinez General Plan Update forecasts a traffic noise level increase of 1 dBA Ldn along the adjacent segment of Pacheco Boulevard by the year 2040, with the future Ldn projected to reach 71 dBA at 75 feet from the roadway centerline. 271 DRAFT 36 Common outdoor us areas are proposed along the south and east boundaries of the site. Existing noise levels measured in these areas ranged from 55 to 59 dBA Ldn. By 2040, the unmitigated noise level would be expected to increase by 1 dBA Ldn and would range from 56 to 60 dBA Ldn. The project also proposes the construction of a 6-foot masonry wall along the south boundary of the site that would provide additional noise reduction. Therefore, future exterior noise levels would be less than 60 dBA Ldn and within the “normally acceptable” noise and land use compatibility range identified for residential land uses. Potential Impact: As shown on Figure 11-5 O of the Noise Element, the subject property is within an area of the County that is identified as having nose levels range above 60 decibels. The introduction of a new residential apartment building could introduce new noise sources including temporary noise from construction activities. There may be periods of time where there would be loud noise generated from the construction equipment, vehicles, and tools that would impact nearby residences and businesses. Additionally, outdoor-to-indoor noise may also be present due to the location of the project in close proximity to residences and Pacheco boulevard. Thus, the following mitigation measures shall be implemented. Mitigation Measure Noise 1: All windows and doors shall have the minimum ratings STC 26 and mechanical ventilation installed for the building. Mitigation Measure Noise 2: The following construction restrictions shall be implemented during project construction and shall be included on all construction plans. Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, whichever occurs first, the applicant shall provide evidence that the construction restrictions and requirements are included on the face of the construction plans. 1. The applicant shall make a good faith effort to minimize project-related disruptions to adjacent properties, and to uses on the site. This shall be communicated to all project-related contractors. The applicant shall notify neighbors within 300 feet of the subject property at least one week in advance of demolition, grading, and construction activities. 2. The project site shall be maintained in an orderly fashion at all times. All random debris and trash shall be disposed of in a timely manner. The project site must maintain and keep dust down by watering the site by use of a water truck, water hose, street sweeping and other dust control and maintenance measures. 3. A publicly visible sign shall be posted on the property with the telephone number and person to contact regarding construction-related complaints. This person shall respond and take corrective action within 24 hours. The CDD phone number to call in complaints shall also be visible to ensure compliance with applicable regulations. 4. The applicant shall require their contractors and subcontractors to fit all internal combustion engines with mufflers which are in good condition and shall locate stationary noise- generating equipment such as air compressors as far away from existing residences as possible. 5. The construction contractor shall ensure that unnecessary idling of internal combustion engines (i.e., idling in excess of 5 minutes) is prohibited. 272 DRAFT 37 6. The construction contractor shall utilize “quiet” models of air compressors and other stationary noise sources where technology exists. 7. 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. 8. Large trucks and heavy equipment are subject to the same restrictions that are imposed on construction activities, except the hours are limited to 9:00 am to 4:00 pm. This condition applies to all heavy construction equipment that vibrates. 9. Unless specifically approved otherwise via prior authorization from the Zoning Administrator, all construction activities shall be limited to the hours of 8:00 A.M. to 5:00 P.M., Monday through Friday, and are prohibited on State and Federal holidays on the calendar dates that these holidays are observed by the State or Federal government as listed below: New Year’s Day (State and Federal) Birthday of Martin Luther King, Jr. (State and Federal) Washington’s Birthday (Federal) Lincoln’s Birthday (State) President’s Day (State) Cesar Chavez Day (State) Memorial Day (State and Federal) Juneteenth National Independence Holiday (Federal) Independence Day (State and Federal) Labor Day (State and Federal) Columbus Day (Federal) Veterans Day (State and Federal) Thanksgiving Day (State and Federal) Day after Thanksgiving (State) Christmas Day (State and Federal) For specific details on the actual day the State and Federal holidays occur, please visit the following websites: Federal Holidays: Federal Holidays (opm.gov) California Holidays: https://www.calhr.ca.gov/employees/pages/state-holidays.aspx Complying with Noise 1 and Noise 2 will reduce interior noise levels to a level below the County’s interior standard of 45 dBA DNL and will reduce the amount of construction generated noise during project construction stages. By incorporating mitigation measures Noise 1 and Noise 2, the project shall have a less than significant impact on temporary or permanent increases in ambient noise levels in the vicinity of the project site, and the project will substantially comply with the Noise Element of the County’s General Plan. b) Less Than Significant Impact With Mitigation Incorporated: The proposed project for a 24-unit is a type of use that will not consist of any manufacturing, processing, or other activities that would typically result in excessive groundborne vibrations or groundborne noise would be 273 DRAFT 38 temporary in nature and would be limited to the restricted construction hours as typically conditioned for development permits approved by the County. These groundborne vibrations would be temporary in duration, however, nearby residences, business, and/or schools may be affected. Nevertheless, implementation of mitigation measure Noise 2 will reduce potential project impacts (that would result in the generation of groundborne vibration or noise to less than significant levels. c) No Impact: The project site is not located within two miles of a public airport or private airstrip, nor is it located within an area covered by the County’s Airport Land Use Compatibility Plan. The nearest airport facility is the Buchanan Field, approximately 2.3 miles southeast of the project site. Thus, the proposed project would not expose people to excessive noise levels from either Buchanan Field or a private airstrip and there is no impact.

Received on May 12, 2022. Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 14. POPULATION AND HOUSING – Would the project: a) Induce substantial unplanned population growth in an area, either directly (e.g., by proposing new homes and businesses) or indirectly (e.g., through extension of roads or other infrastructure)? b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere? SUMMARY: a) Less Than Significant Impact: The project includes the construction of a three-story apartment building that proposes 24-units of residential (apartments) living spaces. Based on the United States Census Burau’s estimate of 2.48 persons per household (between 2017-2021) for Martinez, the project would potentially increase the population by an estimated 60 people. Since this project would result in a relatively small change in the population (per the United States Census Bureau date July 1, 2022, Martinez has an estimated population of 36,447), which means that the project would result in an approximately 0.16% percent increase in population for the area. This population increase would not require the extension of roads or other infrastructure. Therefore, the project would be less than significant. 274 DRAFT 39 b) No Impact: The proposed residential development will be constructed on a vacant lot that has been previously zoned for multi-family residential development. There is no need to alter or remove any of the surrounding residential units in order to establish the proposed development. Thus, the construction and establishment of the proposed 24-unit apartment complex would not displace any person, nor necessitate the construction of replacement housing elsewhere.

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 15. PUBLIC SERVICES – 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) Parks? e) Other public facilities? SUMMARY: a) Less Than Significant Impact: Fire protection and emergency medical response services for the project vicinity are provided by the Contra Costa County Fire Protection District. The project site is located within a 2.3 mile drive from Contra Costa County Fire Station 14, 2.7 mile drive from Contra Costa County Fire Station 9 and 3.3 mile drive from Contra Costa County Fire Station 13. The project is required to comply with the applicable provisions of the California Fire Code, the California Residential Code, and the Contra Costa County Ordinances that pertain to emergency access, fire suppression systems, and fire detection/warning systems. The proposed project has been reviewed by the Contra Costa County Fire Protection District. In a comment letter dated November 15, 2021, the fire district reviewed the project and did not indicate that a new fire protection facility would be needed as a result of the project. When it comes time to submit for building permits for the proposed project, the construction drawings would have to be reviewed and approved by the Contra Costa County Fire Protection District. As a result, the project’s potential impacts on fire protection would be less than significant. b) Less Than Significant Impact: Police protection and patrol services in the unincorporated Martinez area and the project vicinity are provided by the Contra Costa County Sheriff’s office. The Public Facilities/Services Element of the County General Plan requires 155 square feet of station area per 1,000 population in unincorporated Contra Costa County. As discussed earlier 275 DRAFT 40 in this study, the proposed project will create 24 residential (apartment units) which could potentially increase the population by an estimated 60 people (as discussed in the Population and Housing Section above.) This minimal population increase would not impact the County’s ability to maintain a Sheriff facility standard of 155 square feet of station area and support facilities per 1,000 members of the population. Thus, the project would not result in the need for new or expanded police protection facilities or services in the County. c) Less Than Significant Impact: The project site is located within the jurisdiction of the Martinez Unified School District and would induce a student increase to their classroom numbers. The project was referred to the Martinez Unified School District for comments. At the time of the completion of this study, no indication was received from the school district that expansion of existing school facilities would be necessary. However, to address student growth in school districts as a result of residential developments in the County, a per-square-foot school fee amount is determined by the school district. Prior to issuing building permits, the County Building Inspection Division collects the school fees on behalf of the respective school district as part of the overall building permit fees or requires a receipt showing payment of the applicable fee to the school district. Payment of the development fees pursuant to State regulations for school services would reduce impacts to neighborhood schools to less than significant levels. d) Less Than Significant Impact: The policy for Parks and Recreation in the Growth Management element of the County General Plan indicates that a standard of 3 acres of neighborhood parks per 1,000 persons should be maintained within the County. As stated previously, the project would not cause a significant population increase in the Martinez community. The applicant has proposed to landscape 20% of the project site as an outdoor area for use of future residents. While the project as proposed will not result in a significant increase in the County population, all residential projects are required to pay a Park Dedication and Park Impact fees which are adopted by the County Board of Supervisors to the County, which will be used to acquire park land and develop parks and recreation facilities to serve new residential development in the unincorporated County. Therefore, as the applicant has elected to pay an in-lieu fee instead of constructing new park areas in order to comply with the County Park Dedication Ordinance, there is no potential for the proposed project resulting in a substantial adverse environmental impact as a result of the construction of new or expanded parks. e) Less Than Significant Impact: During staff’s initial review of the proposed development and prior to deeming the project complete, project-specific comments were solicited from various local agencies and other interested parties in order to alert County staff and the applicant to any additional permitting, improvements, etc., that may be required as part of the project. Among the groups solicited for this project were the Contra Costa County Water District and MT. View Sanitary District. No indication of a need for new or expanded facilities was provided in the comments. The Contra Costa Library operates 28 facilities in Contra Costa County, including the Martine – Contra Costa County Library, located approximately 2.3 miles west of the project site. The Contra Costa Library system is primarily funded by local property taxes, with additional revenue from intergovernmental sources. A portion of the property taxes on the project site 276 DRAFT 41 would go to the Contra Costa Library system. Accordingly, the impact of the use of the public libraries by people living in the 60 residential (apartment) units would be less than significant. Contra Costa County Health Services District (CCCHSD) operates a regional medical center (hospital) and 10 health centers and clinics in the County. CCCHSD is primarily funded by federal and state funding programs, with additional revenue from local taxes. Since significant impacts to public facilities, such as hospitals are usually caused by substantial increases in population, the potential impact of the use of public health facilities by people living in the 60 residential (apartment) units would be less than significant.

Environmental Issues Potentially Significant Impact Less Than Significant With Mitigation Less Than Significant Impact No Impact 16. RECREATION a) Would the project 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) Does the project include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment? SUMMARY: a) Less Than Significant Impact: The proposed development will induce a small population increase in the area, and as a result, it is anticipated that the use of neighborhood and regional parks in the area will also increase. Pursuant to the Growth Management Element of the County General Plan, the standard is to have a minimum of 3 acres of neighborhood parks for every 1,000 members of the population. The project includes the construction of a new 24-unit apartment complex that will increase the population by approximately 60 persons. This potential increase in population would not be significant enough to warrant the need for a new park, or substantially accelerate the deterioration of any existing parks or other recreational facilities. Additionally, the applicant will be required to pay Park dedication in-lieu fees as part of the project. Therefore, the proposed project would not substantially deteriorate existing park facilities. 277 DRAFT 42 b) Less Than Significant Impact: As previously stated, the potential increase in population would not be significant enough to warrant the need to construct or expand recreational facilities. Additionally, the applicant will be required to pay the County mandated park impact fee for each apartment unit. Park fees are collected to fund the acquisition and development of parks in Contra Costa County to serve unincorporated County residents.

TRANSPORTATION – Would the project: a) Conflict with a program, plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle, and pedestrian facilities? b) Conflict or be inconsistent with CEQA Guidelines Section 15064.3(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? SUMMARY: a) Less Than Significant Impact: The subject property fronts Windhover Way. Windhover Way is 35 feet wide with two 10.5-foot travel lanes and parallel parking permitted on both sides. It has a prima facie speed limit of 25 mph. Windhover Way intersects with Pacheco Boulevard approximately 160 feet south of the proposed location for the project driveway. Pacheco Boulevard is classified as a Route of Significance and is oriented in the east-west direction. It has one travel lane and a bike lane in each direction together with a two-way left-turn lane. The posted speed limit is 45 mph. Parking is permitted on both sides where there is sufficient width. Policy 4-c of the Growth Management Element of the General Plan, and Chapter 82-32 (Transportation Demand Management) require a traffic impact analysis of any project that is estimated to generate 100 or more AM or PM peak-hour trips. In order to evaluate the project, a “Transportation Impact Analysis for the Apartments Residential Development Project,” study was prepared by W-Trans and received by the County on September 7, 2022. The anticipated trip generation for the proposed project was estimated using standard rates published by the Institute of Transportation Engineers (ITE) in Trip Generation Manual, 11th Edition, 2021 for “Multifamily Housing (Low-Rise)” (ITE LU #220). The site is currently undeveloped and therefore not generating any trips. For a conservative analysis, trip reductions resulting from 278 DRAFT 43 nearby transportation options were not applied. Further reductions attributable to internal capture, pass-by or any other trip reductions are not applicable and therefore have also not been applied. The expected trip generation potential for the proposed project is indicated in Table 1 below. The proposed project is expected to generate an average of 162 trips per day, including 10 trips during the a.m. peak hour and 12 during the p.m. peak hour; these new trips represent the increase in traffic associated with the project. Chapter 82-32 of the County Code requires the preparation of a “Transportation Demand Management” (TDM) program, for all residential projects with 13 or more dwelling units. The TDM Ordinance Guide encourages the use of creative and effective ways to reduce motor vehicle trips and their associated impacts created by new development projects. To minimize parking demand and reduce vehicle trips, the applicant may consider, but should not be limited to, reducing the number of parking spaces, providing bicycle and pedestrian infrastructure, providing transit passes, unbundling the price of parking from rent, providing emerging mobility options (e.g., electric scooters, bike share, etc.), and other strategies commonly used to minimize parking demand and automobile trips. Thus, W-Trans prepared a draft TDM program dated September 13, 2022 and received by the County on September 22, 2022 for the Apartment complex which recommends similar TDM measures. The draft TDM program concluded that the proposed pedestrian bicycle and transit facilities would be adequate to serve the project as proposed; the number of short and long term bicycle parking spaces proposed would be greater than the County’s requirement and that the implementation of the TDM program would reduce vehicle trips. Staff of the County’s Transportation Planning division further recommends that a final TDM Program and a TDM Coordinator be required as conditions of approval. Since the proposed project would generate less than 100 peak hour trips, a traffic impact analysis is not required in accordance with General Plan Policy 4-c. In addition, as recommended by County Transportation Planning staff, compliance with the County’s Electric Vehicle (EV) Ordinance and requiring a final TDM program and a TDM Coordinator as conditions of approval would ensure that the project results in a less than significant impact on programs, plans, ordinances or policies regarding transit, roadway, bicycle, and pedestrian facilities. b) Less Than Significant Impact: CEQA provides guidelines for analyzing transportation impacts relating to vehicle miles travelled (VMT) resulting from the project. The Governor’s Office of Planning and Research (OPR) established recommendations for identifying and mitigating transportation impacts within CEQA and published a final Technical Advisory in December of 2018 that advises lead agencies to conduct a screening process to “quickly identify when a project should be expected to cause a less-than-significant impact without conducting a detailed study.” As mentioned above, W-Trans prepared a “Vehicle Miles Traveled (VMT) Evaluation” 279 DRAFT 44 on behalf of the project applicant to identify whether the project would be expected to cause a significant impact and, thus, require a detailed VMT study. W-Trans identified the following project screening criteria as part of their assessment. Consideration was given to the project’s potential generation of Vehicle Miles Traveled (VMT). As a result of SB 743, the Board of Supervisors adopted a VMT policy on June 23, 2020, in their document Transportation Analysis Guidelines. Guidance provided in this document recommends the use of screening thresholds to identify when a proposed project is presumed to result in a less-than-significant impact without conducting a detailed study. According to the Contra Costa County Travel Demand Model estimates, the Countywide home- based average VMT per resident is 19.4 miles. Concurring with guidance provided by this document, a project located anywhere in the County which generates a VMT that is 15-percent or more below this value, or 16.5 miles per resident, should be expected to cause a less-than- significant VMT impact and would not require further VMT analysis. The project would be located within Traffic Analysis Zone (TAZ) 20034 of the Contra Costa Travel Demand Model which has a home-based VMT of 16.0 miles per resident. Because this per capita VMT rate of 16.0 is lower than the significance threshold of 16.5 miles, the project is presumed to have a less-than-significant VMT impact and does not require further VMT analysis. Further, adjacent TAZs west of I-680, including 20033 and 20038, also have a per capita VMT rate that is less than the significance threshold so are consistent with TAZ 20034. A summary of the VMT findings is provided in Table 4 below. As shown in the table above, the project will a lower VMT rate than the significance threshold. Per CEQA section 15064.3(b) – Determining the Significant of Transportation Impacts, a transportation project that does not exceed the significant threshold is considered to have a less than significant transportation impact. Therefore is determined to not be inconsistent with CEQA Guidelines Section 15064.2(b). c) Less Than Significant Impact: The subject property fronts Windhover Way, which is 35 feet wide with two 10.5-foot travel lanes and parallel parking permitted on both sides. It has a prima facie speed limit of 25 mph. As shown on Figure 5-2 (Roadway Network Plan) of the General Plan Transportation and Circulation Element, Windhover Way is not considered to be an existing or proposed arterial, expressway, or freeway. According to the project plans, the site will have access from a private driveway located on Windhover Way, approximately 160 feet north of Pacheco Boulevard. This will be the only access point to and from the proposed 280 DRAFT 45 project. The proposed apartment building will be setback approximately 100 feet from the roadway entrance, therefore, not creating any site obstructions or hazards in relation to the Windhover Way circulation. As part of the review process, the County referred the project out to the Contra Costa County Public Works Department for review. In a Staff Report dated December 19, 2022, the Public Works Department stated that there is no need to “further widening or frontage improvements are necessary with this development,” and provided a standard condition of approval that requires the applicant to adhere to Chapter 82-18, “Applicant shall provide sight distance at the intersection of the private driveway with Windover Way in accordance with Chapter 82-18 “Sight Obstructions at Intersections” of the County Ordinance Code. The applicant shall trim vegetation, as necessary, to provide sight distance at this intersection, and any new signage, landscaping, fencing, retaining walls, or other obstructions proposed at this intersection shall be setback to ensure that the sight line is clear of any obstructions.” No substantial changes to the existing transportation system are proposed with this application. Compliance with the Public Works conditions of approval will result in the project having a less than significant impact on the Windhover Way right-of-way and is not expected to substantially increase hazards due to geometric design features or incompatible uses. d) Less Than Significant Impact: The project was referred to the Contra Costa County Fire Protection District for agency comments. In a comment letter dated November 15, 2021, the Fire Protection District stated that the project shall comply with the applicable California Fire Code, the California Building Code, the California Residential Code and Local and County Ordinances and adopted standards. All construction plans will be subject to the applicable Fire Code that is in effect at the time when the application for a building permit is submitted. Additionally, the applicant will work with the Fire Protection District to submit construction plans for review and approval prior to building permit issuance. Therefore, the routine review of construction plans will ensure that the proposed project has no potential for adversely impacting existing emergency access to the subject property or other properties within the County.

TRIBAL CULTURAL RESOURCES – Would the project 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) 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)? b) 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? SUMMARY: a-b) Less than Significant Impact With Mitigation: As discussed in the Cultural Resources section 5of this study, there are no known existing structures located at the project site that are listed on the Contra Costa County’s Historic Resource Inventory, or the California’s Register of Historical Resources, or the National Register of Historic places, nor is there any building or structure that qualifies to be listed. The project site is vacant. In addition, the project was referred out to the California Historical Resources Information System (CHRIS) to which they responded in a letter dated November 22, 2021, stating that “the proposed project area has a low possibility of containing unrecorded archaeological sites.” Additionally, there is no evidence in the record at the time of completion of this study that indicates the presence of human remains at the project site. On May 23 and May 24, 2021, a Notice of Opportunity to Request Consultation for the proposed Apartment Building was sent to the Wilton Rancheria and the Confederated Villages of Lisjan Nation, two California Native American tribes that are traditionally and culturally affiliated with the geographic area. No requests for consultation or responses regarding tribal cultural resources have been received from California Native American tribes at the time of completion of this study. Potential Impact: As discussed previously in Section 5, subsurface construction activities have the potential to damage or destroy previously undiscovered historic and prehistoric resources. Therefore, the implementation of Mitigation Measure Cultural 1 and Mitigation Measure Geology 6 will ensure that project-related impacts to previously undiscovered and unknown cultural resources will be less than significant.

UTILITIES AND SERVICE SYSTEMS – Would the project: a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electric power, natural gas, or telecommunications facilities, the construction of which could cause significant environmental effects? b) Have sufficient water supplies available to serve the project and reasonably foreseeable 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 management and reduction statutes and regulations related to solid waste? SUMMARY: a) Less Than Significant Impact: The project site is located in a developed, urbanized area of Unincorporated Martinez, which is served by existing water, sewer, storm drain, electric power, natural gas and telecommunications services. There is no indication from any utility service provider that the proposed residential complex would result in a need to relocate, expand, or construct new facilities in such a way as to cause significant environmental effects. Water: The new development is located within the service area of the Contra Costa Water District. Project plans have been sent to the Water District as part of the initial review process. In a letter dated November 18, 2021, the Water District provided comments stating that the new development will require a fire service, a domestic service and an irrigation service. The letter also requested that the applicant work with the Water District engineering services to request water service for the site. The Contra Costa Water District staff has reviewed the project application documents regarding the provision of new water service pursuant to their water service regulations and there has been no indication from the water company that the proposed project would exceed the capacity of the existing public water infrastructure. Wastewater treatment: The project is within the MT. View Sanitary District service area, which is the agency responsible for ensuring that applicable wastewater treatment requirements of the Regional Water Quality Control Board are met and maintained. The wastewater generated by 24 new apartment dwelling units would incrementally increase wastewater flows in the MT. View Sanitary District system. Project plans have been sent to MT. View Sanitary District as 283 DRAFT 48 part of the initial review process, and there is no indication that the proposed project would exceed their ability to provide sewer services with the currently available facilities. In a returned comment letter dated November 17, 2021, MT. View Sanitary District requested that the applicant submit sewer improvement plans to the District and that a sewer permit application shall be required to be obtained from the District. Therefore, there is no indication that the project would require expansion of the wastewater treatment system. Storm water drainage: As discussed in the Hydrology and Water Quality section above, the applicant has submitted a preliminary Storm Water Control Plan (SWCP) designed with project storm water controls including permeable AC pavements to be used in the parking stalls, landscaping and bioretention facilities. The project proposes to capture stormwater runoff from the site into a bioretention facility onsite which will discharge to an existing 18” storm drain in Windhover Way. The applicant also is requesting an exception to Division 914 of the County Ordinance. The storm water and drainage facilities were reviewed by the Contra Costa County Public Works department and in a Staff Report and Recommended Conditions of Approval dated December 19, 2022, Public Works stated that they are not averse to granting the exception. Additionally, they deemed the applicant submitted Preliminary Stormwater Control Plan dated February 22, preliminary complete. Conditions of approval from Public Works is required a final Stormwater Control Plan which will be submitted prior to the applicant obtaining a building permit. The Final Storm Water Control Plan (SWCP) will be accompanied by a Stormwater Control operation and Maintenance Plan and will be required to be in compliance with the County’s National Pollutant Discharge Elimination System and shall be consistent with the County’s Stormwater Management and Discharge Control Ordinance. Based on the incorporation of a SWCP to control the increased runoff, the review by the County agency responsible for enforcing drainage standards, and upon implementation of the conditions of approval from the Contra Costa County Public Works Department, the proposed project would have a less than significant adverse environmental impact on stormwater or wastewater treatment facilities. Electric/Natural Gas: The project is within the service territory of PG&E for electric and natural gas service. It is anticipated that the project will connect to underground electric and/or natural gas connections. There is no indication that the construction of new or expanded electric or natural gas services is required for the ongoing operation of the project. Temporary power for construction activities would also be provided by PG&E. The applicant will be required to apply for temporary power and follow the permitting process for connecting to the electrical grid. Telecommunication Services: Existing telephone, cellular, internet, and cable television are available within the project site’s vicinity. The project site would connect to these services provided by several different providers, and there is no indication that the 24 new residential units would result in the need for expanded services such as new or larger wireless facilities. By following the processes required to connect to existing water, wastewater treatment, storm water drainage, electric power, natural gas, or telecommunications facilities, the impacts of the project concerning these utilities and services would be less than significant. 284 DRAFT 49 b) Less Than Significant Impact: The project site is presently served by municipal water supplies from the Contra Costa Water District. According to County records, the project parcel is not located in an area with a Groundwater Act. As discussed in subsection-a above, the new development will be required to work with the Contra Costa Water District. The Water District staff has reviewed the project application documents regarding the provision of new water service pursuant to their water service regulations and there has been no indication from the water company that the existing public water infrastructure would have insufficient water supplies to serve the project, or that the project would have a significant impact on the public water infrastructure during dry, and multiple dry years. c) Less Than Significant Impact: As discussed in subsection-a above, the new development is within the MT. View Sanitary District, which is the agency responsible for ensuring that applicable wastewater treatment requirements of the Regional Water Quality Control Board are net and maintained. Project plans were sent to the MT. View Sanitary District as part of the initial review process, and there has been no indication from them that the proposed project would exceed their ability to provide sewer services with the currently available facilities. Nor is there any indication that the project would require expansion of the wastewater treatment system. In a comment letter dated November 17, 2021, the District is requiring the applicant to submit sewer improvement plans for review and approval and to submit a sewer permit for the final District approval. The Sanitary District would connect the dwelling units to its facilities after processing the residential sewer service application and collecting the applicable connection fees, completing a building plan review, and issuing a permit for sewer work. By following this process, the impacts related to the wastewater treatment requirements of the Regional Water Quality Control Board for the San Francisco Bay Region or the Mt. View Sanitary facilities would be less than significant. d) Less Than Significant Impact: The proposed project would generate construction solid waste and post-construction residential solid waste. Construction on the project site would be subject to the CalGreen Construction and Demolition Debris Recovery Program administered by the Department of Conservation and Development at the time of application for a building permit. The Debris Recovery Program requires that at least 65% of construction job site debris (by weight) for all new residential buildings requiring permits that would otherwise be sent to landfills be recycled, reused, or otherwise diverted to appropriate recycling facilities. Thus, although future construction of the apartment buildings would incrementally add to the construction waste, the impact of the project-related increase would be considered to be less than significant. The proposed project would be comprised of residential apartment units, which would generate the type of solid waste similar to that of other medium density residential uses in the vicinity. The apartment building will be required to comply with the County Ordinance which requires solid waste collection for all three waste streams (garbage, recycling and organics.) The project plans indicate that there will be a proposed trash enclosure located behind the frontage, near the front of the building. Regular solid wase removal for households in the Martinez area is provided by Republic Services, which also provides recycling and green waste removal services. Household waste is ultimately destined for the Keller Canyon Landfill, which has enough approximate capacity to continue accepting waste for the next 50 years. Household 285 DRAFT 50 waste from the 24-unit apartment project would incrementally add to the household waste headed to the landfill. However, the potential for the proposed project to exceed the capacity of the currently utilized landfill is minimal, and the impact of the project-related waste would be considered to be less than significant. e) Less Than Significant Impact: As mentioned above, construction at the project site would be subject to the CalGreen Construction and Demolition Debris Recovery Program administered by the Department of Conservation and Development. The Debris Recovery Program requires that at least 65% of construction job site debris (by weight) for most construction types, that would otherwise be sent to landfills, be recycled, reused, or otherwise diverted to appropriate recycling facilities. The proposed project is not expected to produce significant amounts of waste that would present a greater conflict with laws and regulations regarding solid waste than similar multiple and single-family residences in the vicinity. Furthermore, the owner, construction contractor, and future tenants would be subject to applicable federal, state, and local laws related to solid waste. Therefore, the potential for conflict with Federal, State, and local management and reduction statutes and regulations related to solid waste is less than significant.

WILDFIRE – If located in or near the 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? SUMMARY: a) Less Than Significant Impact: The site is not located in an area of State Responsibility Area according to the Contra Costa County’s State Responsibility Area Fire Hazard Severity Zones on the California Department of Forestry and Fire Protection’s Fire Hazard Severity Map. The project site is not located near any state responsibility lands classified as a Very High Fire Hazard Severity Zone. The nearest State Responsibility Area High or Very High Fire zone is located more than 2.5 miles to the west. The project is located in a Local Responsibility Area classified as Urban Unzoned. The project site is in a developed area within the service area of the Contra Costa County Fire Protection District (CCCFPD). The project was routed to the CCFPD, who did not indicate any concerns with an elevated risk of wildfires for the site. The project will be required to comply with current fire codes, including those pertaining to fire sprinklers in new buildings, and driveway and roadway access for firefighting apparatus, and would not require the installation or maintenance of additional infrastructure such as roads or fuel breaks that may exacerbate fire risk. Additionally, the applicant will be required to submit construction plans to the fire department for review and approval before any building permits will be issued to ensure compliance with the applicable fire and building codes. Therefore, the routine review of construction plans will ensure that final construction plans will not result in a condition with inadequate emergency vehicle access. b) Less Than Significant Impact: The project site is not located in or near a state responsibility areas or lands classified as very high fire hazard severity zones. Therefore, the risk of exposing project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire is less than significant. The project is located on a lot with a slight slope, however, surrounding parcels are relatively flat and within an urbanized area and, thus, would not expose people or structures to significant risks as a result of post-fire slope instability or runoff. Development will be subject to review and approval by the Contra Costa County Fire 287 DRAFT 52 Protection District. It is expected that compliance with the California Fire Code, California Building Code, California Residential Code and Local and County Ordinances, will keep the project-related risks associated with wildfires at less than significant levels. c) Less Than Significant Impact: The project site is not located in or near a state responsibility areas or lands classified as very high fire hazard severity zones. The project does not require any road widening or frontage improvements. The project was reviewed by the CCCFPD and does not require the installation of emergency roads, fuel breaks, emergency water sources that may exacerbate fire risk. Additionally, Chapter 96-10 of the County Ordinance Code requires all new utility distribution services to be installed underground, thereby reducing fire risk in the area. Thus, project-related risks (regarding installation or maintenance of associated infrastructure associated with fire risks) shall have a less than significant impact on the environment. d) Less Than Significant Impact: The project site is not located in or near a state responsibility areas or lands classified as very high fire hazard severity zones. The project site contains a slight slope but does not contain any hills or steep topography. Moreover, the surrounding area is relatively flat and is not near a major body of water that would be susceptible to flooding. Therefore, the risk of exposing people or structures to significant risks, including downslope or downstream landslides, as a result of runoff, post-fire slope instability, or drainage changes is less than significant.

MANDATORY FINDINGS OF SIGNIFICANCE a) Does the project have the potential to substantially degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory? b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects.) c) Does the project have environmental effects, which will cause substantial adverse effects on human beings, either directly or indirectly? SUMMARY: a) Less Than Significant Impact With Mitigation: Although the development of the proposed multi-family residential complex would be contained within the 32,820 square foot project site, due to the undeveloped nature of the project site, it has the potential for impacting the environment. As stated in this Initial Study, the project is located in an area that is vacant and surrounding by urbanized uses. There is no evidence in the record that the site or surrounding area contains substantial habitat for fish or a wildlife species or will reduce a rare or endangered plant or eliminate an important period in California history. The project was referred to numerous agencies who provided comments on the project stating that impacts would be minimal. However, due to the undeveloped nature of the project, there is a potential for impacting the environment in relation to undiscovered resources. The project would not substantially degrade the quality of the natural environment because the potentially significant impacts regarding aesthetics, cultural/tribal resources, air quality, noise, geology/soils as identified throughout this initial study, can be mitigated to less than significant levels. Where mitigation measures are enforced as proposed in this Initial Study, the measures will be conditions of approval of the proposed project and the applicant will be responsible for implementation of the measures. Therefore, the potential for substantial impacts to the environment or other resources related to the environment as a result of the proposed project is reduced to a less than significant level. b) Less Than Significant Impact With Mitigation Incorporated: The project site is located within the Urban Limit Line in an area that has been designated for multiple-family high-density residential development. The number of housing units in the Martinez area would increase by 289 DRAFT 54 24-units with the proposed project. The project site is the only vacant parcel located on Windhover Way and is one of a few vacant parcels within a two-mile radius. Staff is aware of one substantial development project in the immediate vicinity within the Martinez area that is under review. Staff is unaware of any substantial development projects in the nearby Martinez area that have recently been approved. The project under review is as follows: 1. (County File #CDDP22-03036) The project includes a Development Plan modification to allow for a 33-unit multi-family residential project in four buildings on two lots with 78 on- site parking spaces. The application also includes a Vesting Tentative Map to allow a 33-unit multi-family residential subdivision. The development would be located on APN 380-220- 044, 3845 Pacheco Blvd, Martinez, CA 94553. The project is currently deemed incomplete during the 30-day application review. This area of the County is readily serviced by the public services and utilities such as water, power, sanitary, and fire protection. The Community Development Division (CDD) generally solicits project specific comments from these agencies as part of the application review process, and design modifications are made based on the advice of each respective agency. The consulted agencies are the governing bodies with proficient knowledge of the needs of their existing infrastructure, and no indication of potential impacts or the need for new or expanded services was noted for the project proposal. Therefore, County CDD staff’s consultation with outside agencies for each project and with implementation of the proposed mitigation measures for this proposed project reduces the potential for significant cumulative environmental impacts related to new or expanded utilities to a less than significant level. The proposed project will have temporary impacts that would occur as a result of construction activities that would be mitigated at the project level. No long-term adverse impacts are anticipated to occur, and as such, the incremental effects of the project would not be considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects. With the implementation of the mitigations described in the sections above, the proposed project would not result in cumulatively considerable impacts on the environment. c) Less Than Significant Impact With Mitigation Incorporated: This Initial Study has disclosed potential impacts on human beings that would be less than significant with the implementation of mitigation measures. All identified mitigation measures will be included as conditions of approval for the proposed project, and the applicant will be responsible for implementation of the measures. As a result, there would not be any environmental effects that will cause substantial adverse effects on human beings, either directly or indirectly. 290 REFERENCES In the process of preparing the Initial Study Checklist and conduction of the evaluation, the cited references were consulted.

Party Responsible for Verification: Project proponent, CDD staff. Compliance Verification: Review of Construction Drawings. Photographic evidence of posted sign. Onsite inspection and monitoring of construction vehicles, equipment, and project site. SECTION 5: CULTURAL RESOURCES Potentially Significant Impacts: Although there is no evidence that there is any specific cultural resources known in in the project area, there is nevertheless a potential for previously unknown 297 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 4 of 11 Building Inspection Division (BID) cultural resources to be uncovered during construction activities requiring excavation or earth movement. Mitigation Measure(s): CULTURAL-1: The following measures shall be implemented during project-related ground disturbance and shall be included on all construction plans. Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the applicant shall provide evidence that the measures and requirements listed below are included on the construction plans. If deposits of prehistoric or historical archaeological materials are encountered during ground disturbance activities, all work within 50 feet of the discovery shall be redirected. A qualified archaeologist certified by the Society for California Archaeology (SCA) and/or the Society of Professional Archaeology (SOPA), and the Native American Tribe that has requested consultation and/or demonstrated interest in the project shall be contacted to evaluate the significance of the finds and suggest appropriate mitigation(s) if deemed necessary. A. All construction personnel, including operators of equipment involved in grading, or trenching activities will be advised of the need to immediately stop work if they observe any indications of the presence of an unanticipated cultural resource discovery (e.g., wood, stone, foundations, and other structural remains; debris-filled wells or privies; deposits of wood, glass, ceramics). If deposits of prehistoric or historical archaeological materials are encountered during ground disturbance activities, all work within 50 feet of the discovery shall be redirected and a qualified archaeologist contacted to evaluate the finds and, if necessary, develop appropriate treatment measures in consultation with the County and other appropriate agencies. If the deposits are not eligible, avoidance is not necessary. If eligible, deposits will need to be avoided by impacts or such impacts must be mitigated. Upon completion of the archaeological assessment, a report should be prepared documenting the methods, results, and recommendations. The report should be submitted to the Northwest Information Center and appropriate Contra Costa County agencies. B. If human remains are encountered, work within 50 feet of the discovery shall be redirected and the County Coroner notified immediately. At the same time, an archaeologist shall be contacted to assess the situation. If the human remains are of a Native American origin, the Coroner must notify the Native American Heritage Commission within 24 hours of this identification. The Native American Heritage Commission will identify a Most Likely Descendant (MLD) to inspect the property and provide recommendations for the proper treatment of the remains and associated grave goods. 298 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 5 of 11 Building Inspection Division (BID) Upon completion of the assessment by an archaeologist, the archaeologist should prepare a report documenting the methods and results and provide recommendations for the treatment of the human remains and any associated cultural materials, as appropriate and in coordination with the recommendations of the MLD. The report should be submitted to the Northwest Information Center and appropriate Contra Costa agencies. Implementing Action: COA Timing of Verification: Upon discovery of archaeological materials or human remains Party Responsible for Verification: Project proponent, CDD staff, consulting Archaeologist Compliance Verification: Review of archaeologist’s report or other verification provided to CDD staff SECTION 7: GEOLOGY AND SOILS Potentially Significant Impacts: The consulting geotechnical engineer indicates potentially expansive and corrosive soils existing on the subject property which can be detrimental to concrete and buried metal such as those used for utilities or reinforcing steel. In addition, conditions in the field may vary from those expected based on field investigation, laboratory tests, and engineering analysis performed by the consulting engineer. Thus, it is critically important that adequate geotechnical review be provided. Additionally, ground disturbance during the project’s construction phase has the potential for disturbing previously unknown unique paleontological resources. In addition to the mitigation measures for Cultural Resources, the following mitigation measures will ensure that in the event unique paleontological resources are discovered, the proper actions are taken to reduce the adverse environmental impacts to unique paleontological resources to a less than significant level. Mitigation Measure(s): GEOLOGY-1: Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the project proponent shall submit a geotechnical report update with the geotechnical review fee in the amount of $3,000, referencing the proposed grading, drainage and foundation plans and providing specific criteria and standards for site grading, drainage and foundation design based on adequate subsurface data, laboratory testing of samples and engineering analysis. The scope of the geotechnical investigation shall address the following potential hazards: (i) expansive soils, (ii) corrosive soils, (iii) siting and design of any required bio-retention facilities and/or other measures that may be recommended to achieve compliance with the clean water requirements of the RWQCB, (iv) possible presence of existing undocumented fills and effective measures 299 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 6 of 11 Building Inspection Division (BID) to control/ mitigate the settlement hazard, (v) provide seismic parameters based on the adopted California Building Code at the time that a residential building permit is requested. GEOLOGY 2: Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the geotechnical report update required by Geology 1, above, shall be subject to review by the County’s peer review geologist, and review/approval of the CDD. Improvement, grading and building plans shall carry out the recommendations of the approved report. GEOLOGY 3: Following rough grading (but prior to commencement of foundation-related work) the project geotechnical engineer shall perform corrosion potential testing of the graded building pad to determine if special precautions shall be required to avoid damage to improvements that are in contact with the ground (concrete or steel). GEOLOGY 4: The geotechnical report required by Geology 1 routinely includes recommended geotechnical observation and testing services during construction. These services are essential to the success of the project. They allow the geotechnical engineer to (i) ensure geotechnical recommendations for the 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 BID approval), based on exposed conditions. The monitoring shall commence during clearing, and extend through grading, including testing services during placement of engineered fill, installation of recommended drainage facilities, and foundation related work. A hard 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 during grading, installation of drainage improvements. Similarly, a hard hold shall be placed on the final building inspection for the apartment building, pending submittal of a letter-report from the geotechnical engineer documenting the monitoring services associated with implementation of foundation-related geotechnical recommendations. The geotechnical monitoring shall include pier hole drilling/ foundation preparation work/ installation of drainage improvements (e.g. collection of roof gutter runoff in a closed conduit and conveying it to a suitable discharge point; and possibly installation of a subdrain system around the perimeter of the foundation to control moisture beneath the foundation). GEOLOGY 5: 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, unless additional grading is reviewed and specifically approved by the Building Inspection Division. 300 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 7 of 11 Building Inspection Division (BID) GEOLOGY 6: Should unique paleontological materials be uncovered during grading, trenching, or other on-site excavation(s), all earthwork within 30 yards of the materials shall be stopped until the Community Development Division (CDD) has been notified, and a qualified paleontologist contacted and retained to evaluate the significance of the find, and, if deemed necessary, suggest appropriate mitigation(s). Implementing Action: COA Timing of Verification: Prior to CDD approval of construction documents (GEOLOGY 1 , 2, 4); throughout construction-related activity, and prior to final inspections (GEOLOGY 3). In the event of paleontological materials being discovered (GEOLOGY 6) Party Responsible for Verification: Project proponent, CDD staff, Consulting Geotechnical Engineer, County Geologist Compliance Verification: Review of Geotechnical Engineer’s report; review of construction drawings; or other verification provided to CDD staff SECTION 13: NOISE Potentially Significant Impacts: As shown on Figure 11-5 O of the Noise Element, the subject property is within an area of the County that is identified as having nose levels range above 60 decibels. The introduction of a new residential apartment building could introduce new noise sources including temporary noise from construction activities. There may be periods of time where there would be loud noise generated from the construction equipment, vehicles, and tools that would impact nearby residences and businesses. Additionally, outdoor-to-indoor noise may also be present due to the location of the project in close proximity to residences and Pacheco boulevard. Mitigation Measure(s): NOISE-1: All windows and doors shall have the minimum ratings STC 26 and mechanical ventilation installed for the building. NOISE 2: The following construction restrictions shall be implemented during project construction and shall be included on all construction plans. Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, whichever occurs first, the applicant shall provide evidence that the construction restrictions and requirements are included on the face of the construction plans. 301 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 8 of 11 Building Inspection Division (BID) 1. The applicant shall make a good faith effort to minimize project-related disruptions to adjacent properties, and to uses on the site. This shall be communicated to all project- related contractors. The applicant shall notify neighbors within 300 feet of the subject property at least one week in advance of demolition, grading, and construction activities. 2. The project site shall be maintained in an orderly fashion at all times. All random debris and trash shall be disposed of in a timely manner. The project site must maintain and keep dust down by watering the site by use of a water truck, water hose, street sweeping and other dust control and maintenance measures. 3. A publicly visible sign shall be posted on the property with the telephone number and person to contact regarding construction-related complaints. This person shall respond and take corrective action within 24 hours. The CDD phone number to call in complaints shall also be visible to ensure compliance with applicable regulations. 4. The applicant shall require their contractors and subcontractors to fit all internal combustion engines with mufflers which are in good condition and shall locate stationary noise-generating equipment such as air compressors as far away from existing residences as possible. 5. The construction contractor shall ensure that unnecessary idling of internal combustion engines (i.e., idling in excess of 5 minutes) is prohibited. 6. The construction contractor shall utilize “quiet” models of air compressors and other stationary noise sources where technology exists. 7. 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. 8. Large trucks and heavy equipment are subject to the same restrictions that are imposed on construction activities, except the hours are limited to 9:00 am to 4:00 pm. This condition applies to all heavy construction equipment that vibrates. 9. Unless specifically approved otherwise via prior authorization from the Zoning Administrator, all construction activities shall be limited to the hours of 8:00 A.M. to 5:00 P.M., Monday through Friday, and are prohibited on State and Federal holidays on the calendar dates that these holidays are observed by the State or Federal government as listed below: New Year’s Day (State and Federal) Birthday of Martin Luther King, Jr. (State and Federal) Washington’s Birthday (Federal) 302 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 9 of 11 Building Inspection Division (BID) Lincoln’s Birthday (State) President’s Day (State) Cesar Chavez Day (State) Memorial Day (State and Federal) Juneteenth National Independence Holiday (Federal) Independence Day (State and Federal) Labor Day (State and Federal) Columbus Day (Federal) Veterans Day (State and Federal) Thanksgiving Day (State and Federal) Day after Thanksgiving (State) Christmas Day (State and Federal) For specific details on the actual day the State and Federal holidays occur, please visit the following websites: Federal Holidays: Federal Holidays (opm.gov) California Holidays: https://www.calhr.ca.gov/employees/pages/state-holidays.aspx Implementing Action: COA Timing of Verification: Prior to CDD approval of construction documents and throughout construction-related activity and prior to final inspections; upon receipt of noise complaint(s) Party Responsible for Verification: Project proponent, CDD staff Compliance Verification: Review of Construction Drawings; submittal of pre- construction meeting date to CDD staff; submittal of a copy of notice and distribution list to the CDD; field investigation (in the event of a noise complaint). SECTION 18: TRIBAL CULTURAL RESOURCES Potentially Significant Impacts: There is always a potential to damage or destroy previously undiscovered historic and prehistoric resources during construction related activities. Subsurface construction activities have the potential to damage or destroy undiscovered historic and prehistoric resources. Mitigation Measure(s): 303 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 10 of 11 Building Inspection Division (BID) CULTURAL 1: The following measures shall be implemented during project-related ground disturbance and shall be included on all construction plans. Prior to CDD-stamp approval of plans for the issuance of a building or grading permit, or tree removal, whichever occurs first, the applicant shall provide evidence that the measures and requirements listed below are included on the construction plans. If deposits of prehistoric or historical archaeological materials are encountered during ground disturbance activities, all work within 50 feet of the discovery shall be redirected. A qualified archaeologist certified by the Society for California Archaeology (SCA) and/or the Society of Professional Archaeology (SOPA), and the Native American Tribe that has requested consultation and/or demonstrated interest in the project shall be contacted to evaluate the significance of the finds and suggest appropriate mitigation(s) if deemed necessary. A. All construction personnel, including operators of equipment involved in grading, or trenching activities will be advised of the need to immediately stop work if they observe any indications of the presence of an unanticipated cultural resource discovery (e.g., wood, stone, foundations, and other structural remains; debris-filled wells or privies; deposits of wood, glass, ceramics). If deposits of prehistoric or historical archaeological materials are encountered during ground disturbance activities, all work within 50 feet of the discovery shall be redirected and a qualified archaeologist contacted to evaluate the finds and, if necessary, develop appropriate treatment measures in consultation with the County and other appropriate agencies. If the deposits are not eligible, avoidance is not necessary. If eligible, deposits will need to be avoided by impacts or such impacts must be mitigated. Upon completion of the archaeological assessment, a report should be prepared documenting the methods, results, and recommendations. The report should be submitted to the Northwest Information Center and appropriate Contra Costa County agencies. If human remains are encountered, work within 50 feet of the discovery shall be redirected and the County Coroner notified immediately. At the same time, an archaeologist shall be contacted to assess the situation. If the human remains are of a Native American origin, the Coroner must notify the Native American Heritage Commission within 24 hours of this identification. The Native American Heritage Commission will identify a Most Likely Descendant (MLD) to inspect the property and provide recommendations for the proper treatment of the remains and associated grave goods. Upon completion of the assessment by an archaeologist, the archaeologist should prepare a report documenting the methods and results and provide recommendations for the treatment of the human remains and any associated cultural materials, as appropriate and in coordination with the recommendations of the MLD. The report should be submitted to the Northwest Information Center and appropriate Contra Costa agencies. 304 Abbreviations: Mitigation Monitoring Program Condition of Approval (COA) CDDP21-03031 Community Development Division (CDD) Page 11 of 11 Building Inspection Division (BID) GEOLOGY 6: Should unique paleontological materials be uncovered during grading, trenching, or other on-site excavation(s), all earthwork within 30 yards of the materials shall be stopped until the Community Development Division (CDD) has been notified, and a qualified paleontologist contacted and retained to evaluate the significance of the find, and, if deemed necessary, suggest appropriate mitigation(s).

This proposed development would be 3 stories containing 24 units and would be approximately 22,247 square feet. The proposed project site is a vacant lot located north of Windhover Way and Pacheco Boulevard in unincorporated Martinez, CA 94553. The APN number of the site is 380-220-066 and is within an area where the District serves treated water. The District previously provided comments on the proposed development on November 18, 2021. Since then, the proposed development has changed from a 2- story, 16-unit apartment complex to a 3-story, 24-unit apartment complex. The District has reviewed the request and has the following comments: 1. The premise will require its own service connection, meter, fire service, and reduced pressure (RP) backflow prevention device. 2. RP backflow prevention devices are above ground devices, which, in some cases could reduce water pressure to below standard. Proper planning is necessary to ensure backflow prevention devices are located outside the footprint of the building either in the “right of way” or in an easement provided by applicant. A minimum of three-foot clearance is required around all above ground devices with no vertical impediment. Similarly, fire service will also need to be placed above ground and meet this clearance minimum. Previous plans from 2021 showed fire service placed in a vault located below grade. The District suggests that the applicant work with the District’s Engineering Services Coordinator, Cindy Sweeney, for more details. She can be reached at 925-688-8014 or at csweeney@ccwater.com. 306 Everett Louie, Project Planner Department of Conservation and Development Contra Costa County July 19, 2023 Page 2 Sincerely, Cody

I am one of the owners of a townhome adjacent to this development and have received the notice of public review for  the MND.    It appears the purpose for this notice is only for the review and approval of the environmental impacts and not the site  plan itself. While I have no issues with the MND, I do have some concerns regarding the site plan and proposed  variances.     Listed below are some of the items I noticed when reviewing the site plan which I'm sure the project civil engineer  should be aware of but I just wanted to point out coming from someone who works in land development:    1. Building height:   There's a variance proposal to increase the building heights from the maximum of 30'. I know a lot of my  neighbors have concerns regarding the blocking of natural light, especially since our development already sits  lower than the proposed building. From an engineering standpoint, the main issue I see and need clarification  on is how will the site address the required fire department aerial access with roads less than 26' wide? In  addition, the fire turnaround doesn't seem adequate for the site because the dead end drive aisle is greater  than 150' from the fire turnaround. In addition, the hose pull wouldn't reach the southern eastern corner of  the building.    2. overland and release:  Based on the project description, the site drains from west to east with a 9' differential. There seems to be stormwater  quality measures through out the site with a big basin in the rear. How does the site tackle the highflow storm events  without potentially releasing any runoff off into my townhome development? Based on the natural topography the  runoff will run on to our site.    3. Parking and site accessibility:  While I haven't seen the complete set of plans, it appears the proposed project provides EV and ADA stalls. It would  appear this site would fall under CBC 11B which requires one of the EV stalls to be Van accessibly. Based on the site plan,  it's not clear if this condition is satisfied. In addition, per the latest iteration of the code, EV and ada stalled need to be  provided for separate facilities (i.e. cover and uncovered stalls both need to have ADA and EV stalls), they shouldn't only  be in the covered carports. For the site accessibility, it's not clear if there's a path provided to Windhover Way which I  believe should be required.     Not sure if you would be the right person to reach out to for these site concerns as I know the public hearing is  really for the environmental impacts. But as an owner of one of the adjacent propertys, I wanted to voice out  my concerns: mainly with the building heights and stormwater overland and release as mentioned above.    Let me know your thoughts, thanks    Jesse Ma  311 312 1 Everett Louie From:Kevin Mulcahy

height, drive aisle widths and lot coverage you have to wonder where work trucks and delivery drivers park and turn  around.  They too will be looking for Item #8 on sheet C1.0, "Proposed Dead End Turnaround."    To be consistent with local multi‐unit sites this project should be no higher than 2‐stories, no more than twelve units of  600 s.f. each, with two (2) parking spots per unit.  If compared with all the homes beyond on Windhover Way and  Cormorant Ct. the density is 30 homes on ten times the area, with each house having parking for 2 covered. 2‐3 on  apron, and several more on the street.  As for height, I feel for immediate neighbors.  Can you imagine coming out  your back door, or even worse your front such as at Pineview Townhomes, and look up at a building the size of a cruise  ship looking down on you?  Clearly this development is out of place for this area.  No mitigations can lessen its overall  impact.    Regarding any potential County liability under SB‐10 and developer litigation, I believe the County and ALL local  governments need to resist sweeping mandates from remote State, Federal, and even Global governing bodies. Local  governments need to protect their citizens;  Populations have no other barriers to high‐level over‐reach.  It may SEEM  like the moral high ground is more high density housing and less accommodation for cars, but not if it degrades existing  quality of life.  The County should just be consistent with past standards and not encourage pack 'n' stack housing.  It is a  race to the bottom in quality of life for all, especially for the people who move into those new crowded units.    Per SB‐10,Ch. 65915(e)(1)#1, the County need not waive or reduce development standards (def.65589.5(d)(2)) if there is  a specific adverse impact.  Combined with the points made by my neighbors this project has so many adverse impacts it  is hard to single them out.    Thank you for the chance to comment.    Kevin Mulcahy  kvnmlch@gmail.com  70 cormorant Ct., Martinez,  CA   94553  Cell;   925‐708‐2810        314 From: Charlene Crisafulli-Mulcahy 70 Cormorant Court Martinez, CA 94553 925-708-1523 To: Everett Louie, Planner II Contra Costa County Department of Conservation and Development Dear Mr. Louie, Attached are my Concerns Regarding Windhover Terrace Apartment Project (Revised 7/26/23) County File #CDDP21-03031 Variance on Number of Parking Spaces/Parking Ratios-Only 34 spaces are being proposed for this project. If, as is estimated in the county development plan under the “Public Protection” section, the population will increase by 89.28 people when these apartments are rented, 34 parking spaces will not be adequate to accommodate all the vehicles that will need parking even if only half that number of people owns vehicles. If the parking plan is allowed to pass as is proposed, the extra traffic and parked cars will spill out onto Windhover Way and the adjacent courts which are already overly impacted by parked cars, trucks, and work vehicles. Public transit is not a viable option in this area right now (see current bus schedule for Pacheco Blvd.) so we must assume that most of the apartment residents will be relying on automobiles and trucks for their transportation needs. There are no spaces allowed in this plan for visitor parking. Spaces for disabled parking, car charging and visitor parking should not be included in the total number of proposed parking spaces as they are now. This leaves even less available parking for those who live in the apartment buildings but do not fit into these categories. Please visit the site early mornings, evenings or on weekends to see first-hand the impact this will have on the neighborhood and to see for yourselves that parking on Windhover Way and the adjacent courts is already at maximum capacity. Variance on Parking Stall Sizes-Compact spaces do not work for most modern vehicles. These units need full legal sized parking spaces. Tenants as well as delivery drivers have large pickups, SUVs and vans that need room to park and maneuver. Larger vehicle owners will have no choice but to park on the street. Please be realistic when planning for vehicle parking. 315 Variance on Building Height-The current proposal for a 24-unit three story apartment building conflicts with the surrounding buildings in mass and height even though the county development plan claims that it does not. There are no three-story apartment buildings or projects this large or tall in the surrounding area. Neighbors living in the single-family homes adjacent to the project will be negatively impacted by the tall apartment building overshadowing their back yards. Not only will the noise level increase but the privacy of their back yards will be eliminated. Additionally, views and sunlight will be impeded. Variance on Unit Density-The project approved previously in 2020 was for 16 units. Adding the additional 8 units adds extra burden to the neighborhood in traffic, parking, and noise levels. It is simply too large to squeeze onto a .75-acre parcel. Why not build a project that can accommodate a smaller number of residents but is suitable for this sized parcel and the neighborhood? Providing two apartment units of “affordable housing” should not be reason enough to allow the addition of 8 extra “market rate” apartments. Doing so will clearly make the project too large to be placed onto such a small parcel. Please be realistic and plan a more suitable project for the size of the lot and one that is appropriate for this neighborhood. Increase in Traffic-During peak traffic times, (morning commute, school start times, midday, after school, evening commute as well as the current extra traffic due to refinery change-over) it is already difficult to exit Windhover Way onto Pacheco Blvd. Jumping into the center lane on Pacheco Blvd. is often the only alternative for getting out and is dangerous. Adding this many vehicles to the current traffic level will only make it harder to exit. Please consider a traffic light at Windhover Way and Pacheco Boulevard when deciding on this project. Perhaps you might also consider an alternative or additional exit from the project besides the one on Windhover Way in consideration of safety. Again, please visit the site to observe the traffic flow at peak times so that you have a clear understanding of what current residents are experiencing. Trucked in Soil-Over the past few years owners of this site have trucked in soil from an unknown origin to raise the level of this lot by quite a bit. This is of concern to many of us living nearby as we are not sure where the soil originated from, if it might be contaminated in some way, why they felt the need to raise the lot level and if they even had permission to do so. Hopefully, you can shed some light on this issue and assure us that they had permits to dump this (possibly contaminated) soil near our homes. In general, this project needs a redesign with fewer and smaller units. Just because the zoning allows a certain number of units does not mean that it is a good design for this parcel or for the surrounding community. Tennant and neighborhood quality of life should count here, too. Please consider a redesign of this project on a much smaller scale. Thank you for your consideration in this matter.

The project includes two units for low-income households and one unit for very low-income households and is requesting a Density Bonus of 2 units for a total of 24 units and is requesting a concession to reduce the Open Space requirement from 25% to 20.5%. The applicant is requesting reduction in development standards pursuant to Government Code 65915(p) for parking 321 ZA – January 23, 2023 County File #CDDP21-03031 Page 2 of 15 ratios and 65915(e) for reduced parking stall size, parking setbacks, and total number of covered parking spaces. The project includes approximately seven cubic yards of cut and 3,803 cubic yards of fill. The project requests an exception to Division 914, Collect and Convey requirements. II. RECOMMENDATION A. FIND that the project is statutorily exempt from CEQA under Public Resources Code Section §21159.25 B. APPROVE the Development Plan County File #CDDP21-03031 which includes a Variance Permit, Tree Permit and Density Bonus Request, based on the attached findings and conditions of approval; C. APPROVE the exception from the “collect and convey” requirements of the County Ordinance Code by ADOPTING the attached findings and conditions of approval; D. DIRECT staff to file a Notice of Exemption with the County Clerk. III. GENERAL INFORMATION A. General Plan: The subject property is located within the Multiple-Family Residential – High Density (MH) General Plan land use designation. B. Zoning: The subject property is located within the M-29 Multiple Family Residential (M- 29) District. C. California Environmental Quality Act (CEQA) Compliance: The proposed project is statutorily exempt from CEQA under Public Resources Code Section §21159.25 – residential or mixed-use housing projects that are within an unincorporated area of a County. This exemption applies to multifamily residential housing projects that are consistent with the applicable General Plan Designation and Policies, and applicable Zoning designation and regulations and that are located on parcels no more than five acres. A project can qualify for this statutorily exemption as long as two-thirds of the square footage of the development is designated for residential use and if the project is greater than 6 dwelling units per acre. The proposed project is a 22,247-square-foot building. 100% of the building will be used for residential use which exceeds the two- thirds requirement. All development will either be incidental or primary to residential uses. The project site does not exceed five acres of size and proposing 24 units and is located within the unincorporated area of Contra Costa County. Therefore, the project qualifies under Public Resources Code Section §21159.25. D. Lot Creation: The project site is Parcel C of Parcel Map 143PM48, recorded December 5, 1989 and approved under County File #CDMS88-0115. 322 ZA – January 23, 2023 County File #CDDP21-03031 Page 3 of 15 E. Previous Applications: CDDP16-3009: A Development Plan to construct a 14,124-square-foot 16-unit apartment building. The project was approved by the Zoning Administrator on June 1, 2020, but was subsequently withdrawn. CDSD88-7246: A Condominium Subdivision for an 18-unit condominium project was approved by the Planning Commission on July 11, 1989. The 18-unit development was previously approved under County File #CDDP88-3044. Following multiple extensions, the tentative map expired on July 11, 1998. CDDP88-3044: A Development Plan to construct 18 residential units in two three-story buildings (17,730-square-feet gross floor area). The project was approved by the Zoning Administrator on April 3, 1989. The approved development was never constructed. CDMS88-0115: The project included a three-lot minor subdivision which established the subject property and the two adjacent properties to the south. This was approved by the Zoning Administrator on April 3, 1989. IV. SITE/AREA DESCRIPTION Site Description: The subject lot is approximately 0.77-acres in size (approximately 32,820 square feet) rectangular shaped parcel (with the addition of a 52’ x 70’ strip which extends to the west and connects the parcel to Windhover Way as an access.) The parcel is located on the west side of Windhover Way, approximately 125 feet north of the Pacheco Boulevard and Windhover Way intersection in the in the Pacheco/Vine Hill area. The parcel is vacant and is largely covered with grass and dirt and has eight trees located around the perimeter of the parcel. There is existing curb, sidewalk, streetlights, and underground utilities along the frontage of Windhover Way. Public Works has reviewed the submittal and has indicated that the applicant will not be required to perform further widening or frontage improvements. The general topographic slope of the parcel trends downward from west to east. The elevation starts at 40 feet above mean sea level at Windhover Way and slopes down to 31 feet above mean sea level at the rear of the property. The site currently has access off of Windhover Way which will continue to remain as the access point. The site contains eight trees consisting of London Plane, Carolina Cherry Laurel, California Black Walnut, Glossy Pivet, Olive and Siberian Elm. Surrounding Land Uses: This area along Windhover Way is exclusively occupied by residential development. The adjacent parcels to the north and south host single family residences. To the east of the site is a 13-unit townhouse development. The two properties to the west both host duplexes. Approximately 316 feet northeast is a 12-unit apartment complex. Beyond the immediate neighborhood, along Pacheco Boulevard there are a variety of residential, commercial, and retail uses including multi-family housing, restaurants, schools, storage locations, gas stations, auto repair shops, and other retail services. Parcels 323 ZA – January 23, 2023 County File #CDDP21-03031 Page 4 of 15 within the City of Martinez jurisdiction are located approximately 1,100 feet to the east of the subject parcel. V. PROJECT DESCRIPTION The applicant requests approval of a Development Plan to construct a three-story, 38’-6” tall, 24-unit apartment building. The unit breakdown for the apartment building is provided on the table below. Proposed Dwelling Unit Summary Floor Type of Apartment Number of Units Average Unit Size (gross rentable square feet) Building 1st Floor Two-bedroom unit One-bedroom unit 4 4 650 830 Building 2nd Floor Two-bedroom unit One-bedroom unit 4 4 650 830 Building 3rd Floor Two-bedroom unit One-bedroom unit 4 4 650 830 Total 24 22,247 square feet Building Design and Height The three-story apartment building will have a modern design with a flat roof with stucco siding in a sandstone color blended in with hard shingle siding in a pearl gray color around the proposed balconies. Window trim will be vinyl style in a sand color. Each level has similar floor plan layouts, with the two-bedroom units located on the outer portions of the building and the one-bedroom units located within the interior of the floor. The building would be comprised of three segments separated by staircase breezeways, joined under one unified flat roof to minimize the overall bulk of the structure. Building design incorporates a rectangular shape with all exterior walls of each level at the same location to create one cohesive building from top to bottom while the open breezeway at each level adds depth and variation to the exterior of the building. The overall height of the building will be 38’-6” from natural grade and will appear to be 34’ from finished grade. The project also includes various other improvements including: • Parking related improvements for 34 parking spaces with two ADA accessible spaces and four electric vehicle charging spaces. • Asphalt and permeable pavement. • Landscaping would include 25 trees and numerous shrubs throughout the property for a total of 6,600 square feet of landscaping. A new six-foot fence along the rear property line and a six-foot decorative wall along the side property lines. 324 ZA – January 23, 2023 County File #CDDP21-03031 Page 5 of 15 • Retaining walls along the rear of the property • Fire Hydrant • Six long-term bicycle storage lockers and two short-term bicycle storage spaces. • A 13’-7” tall carport that will cover 16 spaces located on the east side of the parcel. • A 8’-8”, Approx. 261 square foot trash enclosure structure. • Four downward-oriented LED streetlight-style light to be located near the carport to provide site security. • Bioretention Facilities. • Site preparation would include approximately seven cubic yards of cut and 3,803 cubic yards of fill for bioretention treatment facilities and to direct stormwater to off- site drainage infrastructure. • Curb, gutter, sidewalk improvements and driveway ramp would be constructed along the project frontage on Windhover Way. Parking In accordance with California Density Bonus Law, instead of utilizing the parking requirements of the County Zoning Code, the applicant is providing parking in accordance with Government Code Section 65915(p)(1), which states as follows: Upon the request of the developer, no city, county, or city and county shall require a vehicular ratio, inclusive of handicapped and guest parking, of a development meeting the criteria of subdivision (b) that exceeds the following ratios: Parking ratios pursuant to 65915(p) 1 Bedroom Units = 1 off-street parking space (where 1.5 spaces are required) 2 Bedroom Units = 1.5 off-street parking space (where 2 spaces are required) The project will provide a total of 34 parking spaces consisting of 9’ x 17’, 9’ x 18’, 7.5’ x 14.5’ dimensions. These will include compact, accessible and electric vehicle. The project proposes 17 parking spaces, (16 of which will be covered parking spaces) along the eastern property line 13 parking spaces along the northern property line and four compact parking spaces along the entrance. In addition, six long-term bicycle parking spaces and two short- term bicycle parking spaces will be provided. Density Bonus In accordance with California Density Bonus Law, pursuant to Government Code Section 65915(b), the applicant seeks a density bonus for the project. The project would provide 3 affordable units or 13% of the units in the housing development. The project has a maximum density of 22 units under the General Plan Land Use Designation (Multiple-Family Residential High Density (MH). The inclusionary housing requirement is calculated as Fifteen percent of 22 units which yields 3.3 units. Since fifteen percent of the proposed units is 3.3 units, the applicant has indicated that they will pay the full amount of the fractional (0.3) in-lieu fee. 325 ZA – January 23, 2023 County File #CDDP21-03031 Page 6 of 15 Of the required 3.3 units of inclusionary housing required, one unit will need to be available to very low-income families and two units to low-income families. The applicant has indicated that they will comply with this requirement by providing one very low-income unit and two low-income units. Therefore, the project would be eligible for the State density bonus of 13.6 percent, and the total allowable unit count under the MH designation would increase from 22 units to 24 units. By providing one unit to very low-income households, the project is eligible for one development incentive or concession. County Code Section 84-26.14 requires twenty-five percent of the area to not be covered by building, structures, or pavement, but shall be landscaped. Pursuant to Government Code Section 65915(e), the applicant is requesting a reduction of this development standard to allow a 20.5% open space area within the parcel. The applicant has sought relief from the following County standards as provide for in Section 65915(p) and Section 65915(e) of the Government Code: 1) The applicant is providing a total of 34 off-street parking spaces. The parking spaces are located along the north and east property lines and along the entrance to the property from Windhover way. Pursuant to Government Code 65915(p), zero to one-bedroom units shall have one (1) onsite parking space and two-bedroom units shall have one and a half (1.5) onsite parking spaces. In accordance with this standard, the applicant will need to provide 30 parking spaces (the applicant is proposing twelve (12) two-bedroom units and twelve (12) one-bedroom units). The applicant is providing 34 parking spaces. 2) Pursuant to Government Code 65915(e), the applicant is requesting a reduction of development standards to allow a reduced 2’ side yard setback (where 20’ minimum is required) for parking spaces, a reduced 17.5’ front yard setback (where 25’ minimum is required) for parking spaces, a reduced parking stall size to allow 9’ x 18 and 9’ x 17 parking stalls, (where 9’ x 19’ is required), and 16 covered parking where one-half of the required spaces shall be covered.) The covered parking area is located along the eastern property line of the site. Circulation and Access Primary vehicle access to the project site would be from Windhover Way via a driveway that intersects parallel with Windhover Way and the subject parcel. Windhover Way connects to Pacheco Boulevard. Both of these roads are County maintained roads. Windhover Way along the project frontage is approximately 36-foot-wide street within a 56-foot right-of-way. The driveway isle exiting Windhover Way and leading to the parking lot on site will be 26’ wide and will lead into an emergency vehicle hammerhead turnaround. Within the parking lot, the project site will maintain a 25’ parking isle width for the parking spaces along Windhover Way and a 24.5’ parking aisle width for the parking spaces on the east (side) property line. The project proposes to install retaining curbs along the edge of the driveway/parking lot area. VI. AGENCY COMMENTS 326 ZA – January 23, 2023 County File #CDDP21-03031 Page 7 of 15 A.

The table below demonstrates the project’s compliance with the MH General Plan designation. * Density Bonus Request pursuant to Government Code 65915(b)(1)(A) Total Gross Area= 0.75 Acres Total Net Area (80% of Gross) = (The project has no streets, highways and public rights-of-way – therefore gross acre is net) 0.75 Acres 0.6 Net Acres x MH 22 to 29.9 Units Per Acre = Units Per Net Acre 16 to 22 units allowed Proposed Development 24 units* 328 ZA – January 23, 2023 County File #CDDP21-03031 Page 9 of 15 Thus, as proposed the multi-family project is consistent with the Contra Costa County General Plan development guidelines for the MH land use designation. In addition to projects having to comply with the General Plan Density, a project has to comply with the General Plan Policies for development within the Vine Hill/Pacheco Boulevard Specific Geographic Area, as outlined below: Policies For The Vine Hill/Pacheco Boulevard Area: The project site is located within the Vine Hill/Pacheco Boulevard area. As such, the following general plan policies for this area are applicable to the project and the project is consistent with these policies. • Policy 3-105: The scenic assets and unstable slopes of the Vine Hill Ridge are to be protected for open space/agricultural use. The proposed project is not located on or near Vine Hill Ridge. Therefore, the project will not impact the open space/agricultural use of that area. • Policy 3-106: The residential neighborhood east of I-680 shall be buffered from the industrial/landfill-related uses. The project parcel is located west of I-680, therefore this policy does not apply to the project. • Policy 3-107: Approximately 40 acres of land south of the Burlington Northern Santa Fe tracks, between Morello and Pacheco, is designated Agricultural Lands, to encourage the continued operation of the Viano family vineyards and winery. The project parcel is not located within the land designated in the policy. The project parcel is over 1,500 feet northeast of the Viano family vineyards and winery. Therefore, the project will not conflict with this policy. Based on the consistency with the applicable policies and land use designation standards, the project would conform with the County’s General Plan. B. Housing Element Compliance: A component of preparing the County’s Housing Element for the General Plan is the identification of vacant and underutilized suits 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). In order to assess whether this residential development application is subject to requirements of California Government Code section 65863, staff reviewed the site inventory for the adopted 2014 Housing Element and determined that Assessor’s Parcel 329 ZA – January 23, 2023 County File #CDDP21-03031 Page 10 of 15 Number 380-220-066 is not among the parcels listed in the inventory of residential sites which were relied upon to meet the County’s share of regional housing needs. Nevertheless, the project includes a total of 24 residential units. The project includes one-bedroom and two-bedroom units. These unit types will increase housing opportunities for different size households for different income categories. As previously stated, this project maximizes the housing density and development of the site and includes a density bonus of nine percent above the base unit density for the site. Therefore, the project will contribute towards the regional housing need for the County and provide needed housing units for the region. C. Zoning Consistency: The subject property is within the M-29 Multiple Family Residential (M-29) Zoning district. County Code 84-26.402 – Uses – Permitted (3) states that Multiple family buildings, but not including motels or hotels, is permitted use. Therefore, the proposed project is a permitted use within the M-29 Zoning. With the included variances and concessions pursuant to Government Code Section 65915(e), the application is consistent with the districts’ development standards and the County Zoning Ordinance. The district’s zoning development standards dictate allowable development in the area. The project would require two variances from these standards, building height and reduced driveway aisle width and would utilize the Density Bonus Request to request a concession to reduce the open space requirement and a reduction for parking stall size, parking setback and total number of covered parking spaces. To build a structure of this size to accommodate the density bonus request, variances and reduction to development standards are required as stated below. Required Proposed Area 10,000 SF 32,830 SF Building Height: Maximum 30 Feet (20 Feet Within 50 Feet of SFR District) 38’-6” (Building Not Within 50 Feet of SFR District) (34’ from Finished Grade) Front Setback: Minimum 25 Feet 17.5’ for parking spaces** Approx. 71’ for building Side Setback: Minimum 20 Feet 3.8’ for parking spaces** 20’ for building Rear Setback: Minimum 20 Feet 21.4’ Unit Density 22 Units allowed 24 Units^ Parking Spaces: Government Code 65915(p) 1 Bedroom Units = 1 off-street parking 2 Bedroom Units = 2 off-street parking Total = 30 off-street parking 34 Spaces** 330 ZA – January 23, 2023 County File #CDDP21-03031 Page 11 of 15 *Variance Request **Government Code 65915 ^Density Bonus Request #Incentive/Concessions The variance request for increased building height and parking aisle width would be consistent with the intent of the zoning district and are necessary given the project site’s constraints. The variance for building height is a result of the necessary lot padding that is required for drainage to be directed to Windhover Way as the lot is lower by almost 6 feet at the rear of the property. The added fill raises the height of the building from 34’ to 38’-6”. The reduced parking isle widths allows for the project allow the project to have more parking spaces and an isle for vehicles to navigate. The reduction in parking isle space allows for more maneuverability and to accommodate additional parking spaces. With the project proposing to meet the minimum landscape coverage, the driveway isle space had to be reduced to accommodate this feature. With just a small reduction in the driveway isle width, the project can provide more parking spaces and landscape area. D. Appropriateness of Use: The proposed 22,247-square-foot, three-story, 24-unit apartment building, and associated improvements (e.g. pavement, utilities, carport, etc.) would be appropriate for the residential area. The new residential development would be consistent with the surrounding neighborhood along Windhover Way, which is comprised of single- and multi-family residential development. The project would both continue the residential development pattern in the immediate vicinity, and the infill development would create updated housing stock in the neighborhood. Furthermore, the project layout and access would provide for reasonable development with no significant or adverse effects to the surrounding community or environment. The applicant has submitted a Transportation Impact Analysis report prepared by W- Trans which concluded that the project would have a less than significant impact to existing traffic levels. Thus, the proposed use would be appropriate and harmonious with the area. E. Inclusionary Housing Ordinance: The project is subject to the Chapter 822-4. Inclusionary Housing Ordinance. Pursuant to Section 822-4.402 of the Inclusionary Housing Ordinance, a residential development of five or more units shall require at least fifteen precent of the rental units to be developed and sold as inclusionary units. The Covered Parking: 24 (50% of Required Parking Spaces) 16** Bike Parking Long Term Short Term 15% of Number of Bedrooms 15% x 36 Rooms = 6 5% of Number of Bedrooms 5% x 36 Rooms = 2 6 Long Term 2 Short Term Lot Coverage: 35% Maximum Per Building (11,490 SF) 10,619 SF Open Area: 25% Minimum 20.5%# Landscape Coverage: Minimum 6,100 (75% of Open Area) 6,600 SF 331 ZA – January 23, 2023 County File #CDDP21-03031 Page 12 of 15 applicant is therefore required to construct 3.3 inclusionary housing units for the project. An Inclusionary Housing Plan was received on December 20, 2022, which proposed to construct three inclusionary units. Of the affordable units, two 830 square-foot units will be available to “lower-income households”, and one 650 square-foot unit will be available to a “very low-income household.” The fractional unit would be satisfied with paying a partial in-lieu fee of $47,917.09. This fee is included as condition of approval #13 in the conditions of approval for this project. F. Parking: The project will provide a total of 34 parking spaces consisting of 9’ x 17’, 9’ x 18’, 7.5’ x 14.5’ dimensions. These will include compact, accessible and electric vehicle. The project proposes 17 parking spaces, (16 of which will be covered parking spaces) along the eastern property line 13 parking spaces along the northern property line and four compact parking spaces along the entrance. As part of the applicant’s Density Bonus request, which is discussed in this Staff Report, the applicant is requesting parking ratios pursuant to Government Code 69515(p). Pursuant to Government Code 65915(p), Upon the request of the developer, no city, county, or city and count shall require a vehicular ratio, inclusive of handicapped and guest parking, of a development meeting the criteria of subdivision (b) that exceeds the following ratios: (A) Zero to one bedrooms: 1 off-street parking space (B) Two to three bedrooms: 1.5 off-street parking space Based on the number of bedrooms proposed, 30 parking spaces would be required for the project. Thus, the project proposes 34 parking spaces, which meets this requirement. County Code 82-16.412- Bicycle Parking requires long-term and short-term bicycle parking to be provided. Multiple-family dwelling projects must provide the following: (A) Long Term – Spaces for 15 percent of the number of bedrooms, or two spaces, whichever is greater. 15% x 36 Rooms = 6 (B) Short Term- Spaces for five percent of the number of bedrooms, or two spaces, whichever is greater. 5% x 36 Rooms = 2 Based on the number of bedrooms proposed, the project would be required to provide six long-term bicycle parking and two short-term bicycle parking. The project has indicated that they will provide a bicycle locker that will allow for six bicycles to be stored and will provide a bike rack that will allow for two bicycles to be stored. Thus, the project proposes 8 total bicycle parking spaces, which meets this requirement. G. Trees: There are eight trees evaluated on the property, representing five different species. The existing trees are located along property boundaries. Eight trees are proposed to be removed to make room for site improvements. A condition of approval (COA # 26) will require a replanting of 13 trees, 24-inch boxed trees and a restitution for these replanted trees. The contingency bond will ensure that the applicant installs the 332 ZA – January 23, 2023 County File #CDDP21-03031 Page 13 of 15 trees according to the approved landscaping plan on sheet L-1. A final landscape plan will be required and the landscaping for the project will be required to comply with the County’s Water Efficient Landscapes Ordinance. H. Stormwater Management and Discharge Control Ordinance: A Stormwater Control Plan (SWCP) is required for applications 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. This project will create 23,790 square feet of impervious surface therefore a stormwater control plan is required. The applicant has provided a Preliminary Stormwater Control Plan, dated February 2022, which has been deemed preliminarily complete. However, it remains subject to future revision, as necessary, during preparation of improvement plans in order to bring it into full compliance with C.3 stormwater requirements. 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 be approved by Public Works Department. Additionally, the location must be approved by Public Works Department. I. 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 waters to an adequate natural watercourse. The property slopes from the northwest corner to the southeast corner, away and considerably below street grade. Stormwater runoff from the site will be captured into the bioretention facility onsite which discharges to an existing 18” storm drain in Windhover Way, effectively diverting the onsite flows. Section 914-2.004 of the County Ordinance prohibits the diversion of surface waters from any development. The applicant has requested an exception from the Advisory Agency (Contra Costa County Public Works Department) per section 92-6.002 of the County Ordinance Code. The Public Works Department reviewed the proposed project and is not opposed to granting the applicant an exception from the collect and convey requirements of the County Ordinance Code. If the off-site conveyance system, ultimate drainage facility or natural watercourse to which stormwater is proposed to be diverted is inadequate, the applicant shall be responsible for all costs related to the construction and/or right-of-way acquisition related to any necessary improvements to make the system adequate. J. Traffic and Circulation: Primary vehicle access to the project site would be from Windhover Way via a driveway that intersects parallelly with Windhover Way and the 333 ZA – January 23, 2023 County File #CDDP21-03031 Page 14 of 15 subject parcel. The subject site fronts Windhover Way, which connects to Pacheco Boulevard, both are County maintained roads. Windhover Way along the project frontage is approximately 36-foot-wide street within a 56-foot right-of-way. There is existing curb, sidewalk, streetlights, and underground utilities along the frontage. No further widening or frontage improvements are necessary with this development. Based on the Transportation Impact Analysis (TIA), the proposed project will not impact the Pacheco Blvd and Windhover Way as the report concluded that the intersection is expected to continue operation at the same Levels of Service with and without the project. The study also reviewed the projects potential generation of Vehicle Miles Traveled (VMT). According to the Contra Costa County Travel Demand Model estimates, the Countywide home-based average VMT per resident is 19.4 miles. Concurring with guidance provided in the TIA, a project located anywhere in the County which generates a VMT that is 15% or more below this value, or 16.5 miles per resident, should be expected to have very little VMT impact and would not require further VMT analysis. The TIA Table 4 states that the project VMT rate would be 16.0. Therefore, the project is expected to have a VMT per capita less than 15% below the countywide VMT per resident and no further VMT analysis is required. The Transportation Planning Section of the Department of Conservation and Development reviewed the TIA and determined that it was sufficient. Conditions of approval as recommended by the Transportation Planning Section are included as condition of approval #34 in the Findings and Conditions of approval for this project. K. Lighting District Annexation: The subject parcel is already annexed into the L-100 lighting district and will require no further annexation. L. Area of Benefit Fee: The applicant will need to comply with the requirements of the Bridge/Thoroughfare Fee Ordinance for the Martinez Areas of Benefit, as adopted by the Board of Supervisors. The fee shall be paid prior to issuance of building permits. M. Drainage Area Fee and Creek Mitigation: The applicant will be required to comply with the drainage fee requirements for Drainage Area 57, as adopted by the Board of Supervisors. This fee shall be paid prior to issuance of a building permit. N. Variance/Exceptions: The applicant is seeking a request for the following variances: • A 38’-6” building height (where 30’ is the maximum allowed) pursuant to County Code Section 84-26.803. • A reduced driveway aisle width of 24.5’ (where 25’ is the minimum required) pursuant to County Code Section 82-16.404(2). The applicant is also requesting an exception to Division 914 of the County Ordinance which requires 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 334 ZA – January 23, 2023 County File #CDDP21-03031 Page 15 of 15 existing adequate public storm drainage system which conveys the storm waters to an adequate natural watercourse. Findings to support approval of the variance requests and exceptions are discussed in the attached Findings and Conditions of Approval. VIII. 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 M-29 Zoning District. The project is consistent with the established area as muti-family residential units are a common occurrence. The design and use of the proposed apartments is consistent with the other uses in the immediate area. The project will also provide additional needed housing and affordable housing units. Therefore, Staff recommends the Zoning Administrator approved County File #CDDP21-03031, based on the attached findings and subject to the attached conditions of approval. Attachments: 1. Findings and Conditions of Approval 2. Maps 3. Agency Comments 4. Special Reports 5. Plans 335 FINDINGS AND CONDITIONS OF APPROVAL FOR COUNTY FILE #CDDP21-03031; WEST COAST LAND AND DEVELOPMENT, INC – PAMELA WEST (APPLICANT & OWNER). I. FINDINGS A. Growth Management Performance Standards 1. Traffic: Policy 4-c under Growth Management Program (GMP) requires a traffic impact analysis be conducted for any project that is estimated to generate 100 or more AM or PM peak-hour trips based upon the trip generation rates as presented in the Institute of Traffic Engineers (ITE). A project generating less than 100 peak-hour trips generally will not create or exacerbate any current traffic problems. The project provided a Transportation Impact Analysis prepared by W-Trans which concluded that the project would generate 10 AM trips and 12 PM trips. Since the proposed development would yield less than 100 peak-hour AM or PM trips, a project-specific traffic impact analysis is not required and the project is assumed to have a less than significant impact on the circulation system in the project vicinity. 2. Water: The GMP requires new development to demonstrate that adequate water quantity can be provided. The subject property currently receives water service from the Contra Costa Water District (CCWD), and the district has stated that water service is available for the project as the entire site is within the water districts service area. 3. Sanitary Sewer: The GMP requires new development to demonstrate that adequate sanitary sewer service is available. The project site currently receives sanitary sewer service from the Mountain View Sanitary District (MVSD) and MVSD sewer mains in the area are available for the project. The district provided a letter stating that the applicant shall submit a sewer permit application with the district for review and approval. 4. Fire Protection: The fire protection standards under the GMP require that a fire station be within one and one-half miles of development in urban, suburban, and central business district, or requires that an automatic fire sprinkler system be installed to satisfy this standard. The project site is within the Contra Costa County Fire Protection District jurisdiction and is located approximately six mins drive time from Contra Costa County Fire Station #14 located at 521 Jones Street in Martinez. The project is required to comply with the applicable provisions of the California Fire Code, the California Residential Code, and Contra Costa County Ordinances that pertain to emergency access, fire suppression systems, and fire detection/warning systems. When it comes time to submit for building permits, the construction drawings would have to be reviewed and approved by the Contra Costa County Fire Protection District. 5. Public Protection: Public protection standards under the GMP require that a Sheriff Facility standard of 155 square feet of station area and support facilities per 1,000 in 336 ZA – January 23, 2022 County File #CDDP21-03031 Findings and COA Page 2 population shall be maintained within the unincorporated area of the County. Based on the United States Census Bureau’s estimate of 2.48 persons per household (between 2017-2021) for Martinez, the project would potentially increase the population by an estimated 89.28 people. Since the project would result in a relatively small change in population, the project would not impact the County’s ability to maintain a Sheriff facility standard of 155 square feet of station area and support facilities per 1,000 members of the population. Thus, the project would not significantly affect the provision of police services to the Martinez area. 6. Parks and Recreation: As the project will add to the County’s population, Condition of Approval (COA) #21 and #22 requires the project proponent to pay applicable Park Impact and Park Dedication in-lieu fees for the new units. These fees, in conjunction with all other Park Dedication fees collected for development within the County, will be used in part to purchase new park land and upgrade existing community parks as determined appropriate by the Board of Supervisors. 7. Flood Control and Drainage: The project is located in Zone X, as designated on the Federal Emergency Management Agency’s Flood Insurance Rate Maps. The project is required to meet collect and convey requirements of the County Subdivision Ordinance Title 9, by constructing the necessary drainage improvements, or obtaining necessary exceptions to the code. The applicant must also comply with the County’s National Pollutant Discharge Elimination System (NPDES) Permit and Stormwater Management and Discharge Control Ordinance, Title 10, for stormwater treatment. With the included exception to Title 9, the new drainage improvements will both meet stormwater discharge requirements for stormwater treatment, while also accommodating all rainwater runoff generated by the project, as required by Title 9. B. Development Plan Findings 1. Required Finding: The proposed project is consistent with the purpose of the zoning district: Project Finding: The purpose of the M-29 Multiple Family Residential (M-29) district is to allow for multiple-family residential district development designed to provide as much compatibility as possible with nearby single-family residential zoning. The project will largely conform to the M-29 District development standards relating to setbacks, lot coverage, and other standards. Variances to the development standards meet the intent of the standards, as required by the Variance findings. The project also has submitted a Density Bonus Request and is requesting parking ratios pursuant to Government Code 65915(p) and multiple reduction to development pursuant to Government Code 337 ZA – January 23, 2022 County File #CDDP21-03031 Findings and COA Page 3 65915(e). With these requests, the proposed project creates a multi-family apartment complex that is a permitted use under 84-26.402(3). 2. Required Finding: The proposed project is architecturally compatible with other uses in the vicinity, both inside and outside the zoning district. Project Finding: Given the density of housing development in the area (townhomes, duplexes, single-family residence), the proposed design does not conflict with the surroundings in building mass or height. The architectural style in this area of the County can be described as a diverse collection of Ranch, Mediterranean, Spanish Revival, and contemporary modern styles. The projects contemporary design would be comprised of three segments separated by staircase breezeways, joined under one unified flat roof to minimize the overall bulk of the structure. Building design incorporates a rectangular shape with all exterior walls of each level at the same location to create one cohesive building from top to bottom while the open breezeway at each level adds depth and variation to the exterior of the building. The façade of the building will have variation with sandstone color stucco alternating with pearl gray shingle siding. C. Variance Findings: 1. Required Finding: Any variance authorized shall not constitute a grant of special privilege inconsistent with the limitations on other properties in the vicinity and the respective land use district in which the subject property is located. Project Finding (Height): The applicant requests a variance to allow a 38’-6” tall building (where 30 feet is the maximum allowed). Given that the height is due to unique topographical characteristics and drainage restrictions, granting of the variance for the building height would not be considered a grant of special privilege. In order to meet drainage requirements that require stormwater to drain to adequate stormwater infrastructure at Windhover Way, the rear of the lot must be padded. Currently, the rear of the lot is almost nine feet lower than the frontage (Windhover Way). The project will pad almost nine feet towards the rear to bring the site level and 4’-6” of padding under the building itself. This extensive amount of padding raises the finished grade under the rear of the building, resulting in a height that exceeds the 30-foot standard if measured from natural grade. Additionally, in order to meet the required density of the General Plan Land Use Designation for this site, the project was required to add more units, which prompted the height increase. Strict application of the zoning code would reduce the amount of units on site by eight, which would result in a total of 16 units which would be at the low end for the General Plan Land Use Designation. For these reasons, the height of the building is not a grant of special privilege inconsistent with the limitations of other properties in the vicinity and respective land use district. 338 ZA – January 23, 2022 County File #CDDP21-03031 Findings and COA Page 4 Project Finding (Driveway Aisle Width): The applicant requests a variance to allow for a 24.5’ driveway aisle width (where 25’ is the minimum required) for driveway aisles with parking of ninety degrees. Granting of the variance for the reduced driveway aisle width would not be a grant of special privilege. The irregular flag-shaped property has an approximately 48 foot-wide by 72 foot-long of strip of land that extends access to Windhover way. The strip of land presents a unique restriction only applicable to this site. The unique shape unreasonable limits development on the property in a way that requires the driveway aisle widths to be slightly reduced in order to maintain circulation and parking spaces. The shape of the lot limits reasonable development on the property. A reduction to the driveway aisle width is necessary to allow for the amount of parking spaces and site improvements. Otherwise, the project would not be feasible. For these reasons, the reduced driveway aisle width is not a grant of special privilege inconsistent with the limitations of other properties in the vicinity and respective land use district. 2. Required Finding: That because of special circumstances applicable to the subject property because of its size, shape, topography, location or surroundings, the strict application of the respective zoning regulations is found to deprive the subject property of rights enjoyed by other properties in the vicinity and within the identical land use district. Project Finding (Height): Given that the additional height is due to unique topographical characteristics and drainage restrictions, granting of the variance for the building height is based on special circumstances. In order to meet drainage requirements that require stormwater to drain to adequate stormwater infrastructure at Windhover Way, the rear of the lot must be padded. The padding ranges from approximately 9 feet at the rear property line to 4’-6” underneath the building. Given that the site slopes away from Windhover Way, the building is required to be raised to address drainage issues. Thus, due to these special circumstances, the strict application of zoning regulations would deprive the subject property of rights enjoyed by other properties developed as multiple-family projects. Project Finding (Driveway Aisle Width): The applicant requests a variance to allow a 24.5’ driveway aisle width (where 25’ is the required minimum). The irregular flag-shaped property has a 48 food-wide by 72-foot-long strip of land that extends access to Windhover way. This unique shape limits the placement and development of a driveway aisle width on the property as there are already numerous other constraints. To provide a driveway aisle for parking spaces to be accessed, the only feasible location is between the proposed parking spaces. The flagged driveway results in additional area on the lot that must be paved in order to reach the larger developable portion of the lot. Thus, a 25’ driveway aisle would not be feasible while also providing parking, open space, 339 ZA – January 23, 2022 County File #CDDP21-03031 Findings and COA Page 5 covered parking and space for the building. Thus, due to these special circumstances, the strict application of the zoning regulations would deprive the subject property of rights enjoyed by other properties developed as multiple-family projects. 3. Required Finding: That any variance authorized shall substantially meet the intent and purpose of the respective land use district in which the subject property is located. Project Finding: Height limits are applied to provide an orderly residential development pattern and, adequate air and light between neighboring development. The 8’-6” of additional height (4’ if measured from finished grade) would substantially meet the intent and purpose of the respective 30-foot height maximum as all building setbacks are met and exceeded. The building would maintain separation from neighboring properties. The variance request will allow for the project to address drainage and topography issues without burdening the applicant. Therefore, it is reasonable to believe that the height would not have a detrimental effect on the adjoining properties and meet the intent and purpose of the respective land use district. Project Finding (Driveway Aisle Width): The applicant requests a variance to allow a reduced 24.5’ driveway aisle width (where 25’ is the minimum required). The driveway aisle width allows for cars to maneuver in and out of parking spaces. The proposed driveway aisle width is only 0.5’ less than the minimum requirement. Due to site constraints, the project has balanced the need to provide the full driveway aisle width with the need to provide for adequate parking spots and landscaping requirements. The loss of 0.5’ les for a driveway aisle width will not have a detrimental effect on the adjoining properties and meet the intent and purpose of the respective land use district. 4. Findings for Granting an Exception Per Section 92-6.002: Request for an exception from Title 9 Offsite Collect and Convey Diversion requirements (Section 914-2.0040) 1. Required Finding: That there are unusual circumstances or conditions affecting the property. Project Finding: The property slopes from the northwest corner to the southeast corner, away and considerably below street grade. There is no storm drain or easement at the lowest corner of the site. On-site drainage facilities will be installed to tie into the existing storm drain on Windhover Way to the west. The storm drain is deep enough to allow for gravity drainage from the stormwater treatment facilities but was not originally intended to accept stormwater runoff from this site. Considering this site’s unusual 340 ZA – January 23, 2022 County File #CDDP21-03031 Findings and COA Page 6 circumstances and conditions, an exception from the County Ordinance Code’s prohibition regarding diversions would be required. 2. Required Finding: That the exception is necessary for the preservation and enjoyment of a substantial property right. Project Finding: The diversion of stormwater is necessary to connect the project to stormwater facilities in the area. A connection at the southeast corner of the property is not currently possible, meaning this infill project is not feasible unless the exception is granted. Additionally, as described above, the drainage infrastructure already exists within the Windhover Way right-of-way making this the most appropriate location. 3. Required Finding: That the granting of the exception will not be materially detrimental to the public welfare or injurious to other property in the territory in which the property is situated. Project Finding: Capacity of the downstream drainage system will be verified to ensure it is sufficient to accommodate the additional runoff. Additionally, stormwater would be directed to existing infrastructure used by other properties in the area. Therefore, the exception will not be materially detrimental to the public welfare or injurious to other properties in the territory in which the subject property is situated. The applicant will be required to provide a drainage report to verify the adequacy of the downstream drainage system. If the receiving system is found to be inadequate the applicant shall be required to improve the system to make it adequate. 5. Tree Protection and Preservation Findings: Required Factors for Granting Tree Permit: The Zoning Administrator is satisfied the following factors as provided by County Code Section 816-6.8010 for granting a tree permit have been satisfied: • 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. • Where the arborist or forester report has been required, and the director is satisfied that the issuance of a permit will not negatively affect the sustainability of the resource. All feasible efforts have been made to retain the maximum number of trees and that development of this project cannot be reasonably accommodated on other parts of 341 ZA – January 23, 2022 County File #CDDP21-03031 Findings and COA Page 7 the property due to the shape and orientation of the property. The trees are required to be removed in order for the appropriate infrastructure can be built to support a project of this size. Development on this property can not occur without the removal of trees. An arborist report was provided which concluded that the trees to be removed are moderate to low health. California Environmental Quality Act (CEQA) Finding The project is statutorily exempt from CEQA environmental review pursuant to Public Resources Code section §21159.25 which exempts certain multi-family housing projects in urbanized unincorporated county areas. This exemption applies to multifamily residential housing projects that are consistent with the applicable General Plan designation and policies, and applicable zoning designation and regulations. Since the project is multifamily residential, conforms to the applicable General Plan designation and policies, and zoning designation and regulations and the project is served by all required utilities and public services, the project is exempt from CEQA. There is no substantial evidence that the project involves unusual circumstances, including future activities, resulting in, or which might reasonably result in, significant impacts which threaten the environment.

Inclusionary Housing and Density Bonus 11. This project is subject to Chapter 822-4, Inclusionary Housing Ordinance. Terms and definitions regarding the Inclusionary Housing Ordinance are pursuant to this chapter. Pursuant to Section 822-4.402(a) of the County Ordinance Code, in a residential development of 22 rental units, at least fifteen percent of the rental units shall be developed and rented as inclusionary units. The applicant, owner, and/or developer (Applicant) is required to construct 3.3 inclusionary units for the project. The Applicant has submitted a revised Inclusionary Housing Plan received December 27, 2022, which proposed to construct three inclusionary units within the housing development. Two units will be available to lower- 344 ZA – January 23, 2022 County File #CDDP21-03031 Findings and COA Page 10 income households (80% Area Median Income (AMI)), and one unit will be available to a very low-income household (50% AMI). The fractional unit of 0.3 would be satisfied with the payment of a partial in-lieu fee. The Applicant submitted a revised density bonus request with their revised inclusionary housing plan received December 27, 2022. As described in the HCI April 19, 2022, memo, the Applicant is eligible for a 24.5% density bonus as the Applicant proposed to build on-site three lower-income units or 13% of the units in the housing development as affordable to lower-income households. For this project, the inclusionary housing units are also the lower income units that qualify the project for a density bonus. The Applicant’s Inclusionary Housing Plan and density bonus request propose a density bonus of 2 units, or a 9% bonus, with one requested concession and various reductions in development standards, bringing the total number of units in the project from 22 to 24. Density Bonus – Concession/Incentive Pursuant to Government Code 65915, the Applicant has proposed a housing development that will contain units that comply with Government Code 65915(b)(1)(A) and may request one concession/incentive for providing 13 percent of the total units of a housing development for lower-income households within the development. For use of the one concession, the Applicant requested reduced open space requirement pursuant to Government Code 65915(d). Additionally, the Applicant has requested parking ratios based on Government Code 65915(p) for a reduced parking requirement. The request also includes reductions in development standards pursuant to Government Code 65915(e) for reduced parking stall sizes, reduced parking setbacks and reduced covered parking. The County accepted the Applicant’s request for reductions in development standards for the following: Density Bonus – Parking Ratio • Parking ratios pursuant to 65915 (p). 1 Bedroom Units = 1 off-street parking space (where 1.5 spaces are required) 2 Bedroom Units = 1.5 off street parking space (where 2 spaces are required) Density Bonus – Reduction of Development Standards • Parking stall sizes of 9 feet x 18 feet and 9 feet x 17 feet (where 9 feet x 19 feet is required) • Front Parking setbacks of 17.5 feet (where 25 feet minimum is required). 345 ZA – January 23, 2022 County File #CDDP21-03031 Findings and COA Page 11 • Side Parking setbacks of 2 feet (where 20 feet minimum is required). • 16 total covered parking (where one-half of the required spaces shall be covered). The County accepted the Applicant’s request for one concession, as follows: • Open space requirement of 20% (where the open space requirement is 25% of land area, with 75% of that area landscaped) Inclusionary Housing and Density Bonus Developer Agreement 12. At least 90 days prior to CDD0-stamp approval of plans for the issuance a building, demolition, or grading permit, whichever occurs first, and with the filing of a condition of approval compliance review, the Applicant shall initiate the County’s preparation and execution of an Inclusionary Housing and Density Bonus Housing Agreement (Agreement), form to be provided by the County, with the County pursuant to County Ordinance Chapter 822-4 - Inclusionary Housing, County Ordinance Chapter 822-2 - Density Bonus, and Government Code 65915 to ensure that two (2) of the approved units are affordable to and occupied by lower-income households, and one (1) of the approved units is affordable to and occupied by a very low-income household. The Agreement shall be submitted to the Board of Supervisors for approval on behalf of the County. Following the execution of the Agreement, the completed Agreement will be filed and recorded on the subject property. The three (3) on-site inclusionary units identified will include: 1 Studio unit at Very Low Income (50% AMI) 2 Two-bedroom units at Lower Income (80% AMI) Maximum affordable rents shall be determined annually by the County and adjusted for family size appropriate for the unit. The continued affordability of all lower-income rental units and very low-income rental units shall remain restricted and affordable to the designated income categories for fifty- five (55) years or a longer period of time if required by the construction or mortgage financing assistance program, mortgage insurance program, or rental subsidy program.

If deposits of prehistoric or historical archaeological materials are encountered during ground disturbance activities, all work within 50 feet of the discovery shall be redirected and a qualified archaeologist contacted to evaluate the finds and, if necessary, develop appropriate treatment measures in consultation with the County and other appropriate agencies. If the deposits are not eligible, avoidance is not necessary. 352 ZA – January 23, 2022 County File #CDDP21-03031 Findings and COA Page 18 If eligible, deposits will need to be avoided by impacts or such impacts must be mitigated. Upon completion of the archaeological assessment, a report should be prepared documenting the methods, results, and recommendations. The report should be submitted to the Northwest Information Center and appropriate Contra Costa County agencies. B. If human remains are encountered, work within 50 feet of the discovery shall be redirected and the County Coroner notified immediately. At the same time, an archaeologist shall be contacted to assess the situation. If the human remains are of a Native American origin, the Coroner must notify the Native American Heritage Commission within 24 hours of this identification. The Native American Heritage Commission will identify a Most Likely Descendant (MLD) to inspect the property and provide recommendations for the proper treatment of the remains and associated grave goods. Upon completion of the assessment by an archaeologist, the archaeologist should prepare a report documenting the methods and results, and provide recommendations for the treatment of the human remains and any associated cultural materials, as appropriate and in coordination with the recommendations of the MLD. The report should be submitted to the Northwest Information Center and appropriate Contra Costa agencies. Geology and Soils 29. Prior to removal of trees or CDD stamp-approval of plans for issuance of building permits (e.g. demolition, grading or building, whichever occurs first, the project proponent shall submit a geotechnical report update referencing the proposed grading, drainage and foundation plans and providing specific criteria and standards for site grading, drainage and foundation design based on adequate subsurface data, laboratory testing of samples and engineering analysis. The scope of the geotechnical investigation shall address the following potential hazards: (i) expansive soils, (ii) corrosive soils, (iii) siting and design of any required bio-retention facilities and/or other measures that may be recommended to achieve compliance with the clean water requirements of the RWQCB, (iv) possible presence of existing undocumented fills and effective measures to control/ mitigate the settlement hazard, (v) provide seismic parameters based on the adopted California Building Code at the time that a residential building permit is requested. 30. Prior to removal of trees or CDD stamp-approval of plans for issuance of building permits (e.g. demolition, grading or building, whichever occurs first, the geotechnical report update required by Condition of Approval #29, above, shall be subject to review by the County’s peer review geologist, and review/approval of the CDD. Improvement, grading and building plans shall carry out the recommendations of the approved report. 353 ZA – January 23, 2022 County File #CDDP21-03031 Findings and COA Page 19 31.

The geotechnical report required by Condition of Approval #29 routinely includes recommended geotechnical observation and testing services during construction. These services are essential to the success of the project. They allow the geotechnical engineer to (i) ensure geotechnical recommendations for the 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 BID approval), based on exposed conditions. The monitoring shall commence during clearing, and extend through grading, including testing services during placement of engineered fill, installation of recommended drainage facilities, and foundation related work. A hard 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 during grading, installation of drainage improvements. Similarly, a hard hold shall be placed on the final building inspection for the apartment building, pending submittal of a letter-report from the geotechnical engineer documenting the monitoring services associated with implementation of foundation- related geotechnical recommendations. The geotechnical monitoring shall include pier hole drilling/ foundation preparation work/ installation of drainage improvements (e.g. collection of roof gutter runoff in a closed conduit and conveying it to a suitable discharge point; and possibly installation of a subdrain system around the perimeter of the foundation to control moisture beneath the foundation). 33. 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, unless additional grading is reviewed and specifically approved by the Building Inspection Division.

This project is subject to Chapter 822-4, Inclusionary Housing Ordinance. Terms and definitions regarding the Inclusionary Housing Ordinance are pursuant to this chapter. Pursuant to Section 822- 4.402(a) of the County Ordinance Code, in a residential development of 22 rental units, at least fifteen percent of the rental units shall be developed and rented as inclusionary units. The applicant, owner, and/or developer (Applicant) is required to construct 3.3 inclusionary units for the project. The Applicant has submitted a revised Inclusionary Housing Plan received December 27, 2022, which proposed to construct three inclusionary units within the housing development. Two units will be available to lower-income households (80% Area Median Income (AMI)), and one unit will be available to a very low-income household (50% AMI). The fractional unit of 0.3 would be satisfied with the payment of a partial in-lieu fee. The Applicant submitted a revised density bonus request with their revised inclusionary housing plan received December 27, 2022. As described in the HCI April 19, 2022, memo, the Applicant is eligible for a 24.5% density bonus as the Applicant proposed to build on-site three lower-income units or 13% of the units in the housing development as affordable to lower-income households. For this project, the inclusionary housing units are also the lower income units that qualify the project for a density bonus. The Applicant’s Inclusionary Housing Plan and density bonus request propose a density bonus of 2 units, or a 9% bonus, with one requested concession and various reductions in development standards, bringing the total number of units in the project from 22 to 24. Density Bonus – Concession/Incentive Pursuant to Government Code 65915, the Applicant has proposed a housing development that will contain units that comply with Government Code 65915(b)(1)(A) and may request one concession/incentive for providing 13 percent of the total units of a housing development for lower- income households within the development. For use of the one concession, the Applicant requested reduced open space requirement pursuant to Government Code 65915(d). Additionally, the Applicant has requested parking ratios based on Government Code 65915(p) for a reduced parking requirement. The request also includes reductions in development standards pursuant to Government Code 65915(e) for reduced parking stall sizes, reduced parking setbacks and reduced covered parking. The County accepted the Applicant’s request for reductions in development standards for the following: • Parking ratios pursuant to 65915 (p). 1 Bedroom Units = 1 off-street parking space (where 1.5 spaces are required) 2 Bedroom Units = 1.5 off street parking space (where 2 spaces are required) 369 • Parking stall sizes of 9 feet x 18 feet and 9 feet x 17 feet (where 9 feet x 19 feet is required) • Front Parking setbacks of 17.5 feet (where 25 feet minimum is required). • Side Parking setbacks of 2 feet (where 20 feet minimum is required). • 16 total covered parking (where one-half of the required spaces shall be covered). The County accepted the Applicant’s request for one concession, as follows: • Open space requirement of 20% (where the open space requirement is 25% of land area, with 75% of that area landscaped) Inclusionary Housing and Density Bonus Developer Agreement 2. At least 90 days prior to the Community Development Division’s (CDD) approval of a building, demolition, or grading permit application, whichever occurs first, and with the filing of a condition of approval compliance review, the Applicant shall initiate the County’s preparation and execution of an Inclusionary Housing and Density Bonus Housing Agreement (Agreement), form to be provided by the County, with the County pursuant to County Ordinance Chapter 822- 4 - Inclusionary Housing, County Ordinance Chapter 822-2 - Density Bonus, and Government Code 65915 to ensure that two (2) of the approved units are affordable to and occupied by lower-income households, and one (1) of the approved units is affordable to and occupied by a very low-income household. The Agreement shall be submitted to the Board of Supervisors for approval on behalf of the County. Following the execution of the Agreement, the completed Agreement will be filed and recorded on the subject property. The 3 on-site inclusionary units identified will include: 1 One-bedroom unit for Very Low-Income (50% AMI) 2 Two-bedroom units for Lower-Income (80% AMI) Maximum affordable rents shall be determined annually by the County and adjusted for family size appropriate for the unit. The continued affordability of all lower-income rental units and very low-income rental units shall remain restricted and affordable to the designated income categories for fifty-five (55) years or a longer period of time if required by the construction or mortgage financing assistance program, mortgage insurance program, or rental subsidy program. Definitions Terms and definitions used in these conditions of approval may be found in the above- referenced County Ordinance Codes and Government Code. 370 A.

Balbas, Director Deputy Directors Stephen Kowalewski, Chief Allison Knapp Warren Lai Carrie Ricci Joe Yee Memo December 19, 2022 TO: Everett Louie, Project Planner, Department of Conservation and Development FROM: Larry Gossett, Senior Civil Engineer, Engineering Services SUBJECT: DEVELOPMENT PERMIT DP21-3031 STAFF REPORT AND RECOMMENDED CONDITIONS OF APPROVAL (West Coast Land Development, Inc./Windhover Way/Martinez/APN 380-220- 066) FILE: DP21-3031 We have reviewed the revised site plan dated March 15, 2022, along with supplemental documents and submit the following comments and recommendations: Background The applicant requests a development permit to construct a 24-unit apartment complex on a vacant 0.75-acre parcel on the east side of Windhover Way in unincorporated Martinez area. A prior application was submitted on the subject property (DP16-3009) for a 16-unit apartment complex, but the previous application was withdrawn. The site lies north of Pacheco Boulevard along Windhover Way. Single family residences lie along the north and south property lines. A townhouse development lies along the east side of the site. Traffic and Circulation The subject site fronts Windhover Way, which connects to Pacheco Boulevard, both are County maintained roads. Windhover Way along the project frontage is approximately 36-foot-wide street within a 56-foot right-of-way. There is existing curb, sidewalk, streetlights, and underground utilities along the frontage. No further widening or frontage improvements are necessary with this development. 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 waters to an adequate natural watercourse. 380 Everett Louie December 19, 2022 Page 2 of 3 The property slopes from the northwest corner to the southeast corner, away and considerably below street grade. Stormwater runoff from the site will be captured into the bioretention facility onsite which discharges to an existing 18” storm drain in Windhover Way, effectively diverting the onsite flows. Section 914-2.004 of the County Ordinance prohibits the diversion of surface waters from any development. The applicant is seeking an exception to Division 914 of the County Ordinance and has provided the following finding in accordance with Section 92-6.002 of the County Ordinance: 1. Required Finding: That there are unusual circumstances or conditions affecting the property. Project Applicability: The property slopes from the northwest corner to the southeast corner, away and considerably below street grade. There is no storm drain or easement at the lowest corner of the site. On-site drainage facilities will be installed to tie into the existing storm drain in Windhover Way to the west. The storm drain is deep enough to allow for gravity drainage from the stormwater treatment facilities but was not originally intended to accept stormwater runoff from this site. Considering this site’s unusual circumstances and conditions, an exception from the County Ordinance Code’s prohibition regarding diversions would be required. 2. Required Finding: That the exception is necessary for the preservation and enjoyment of a substantial property right. Project Applicability: The diversion of stormwater is necessary to connect the project to stormwater facilities in the area. A connection at the southeast corner of the property is not currently possible, meaning this infill project is not feasible unless the exception is granted. Additionally, as described above, the drainage infrastructure already exists within the Windhover Way right-of-way making this the most appropriate 3. Required Finding: That the granting of the exception will not be materially detrimental to the public welfare or injurious to other property in the territory in which the property is situated. Project Applicability: Capacity of the downstream drainage system will be verified to ensure it is sufficient to accommodate the additional runoff. Additionally, stormwater would be directed to existing infrastructure used by other properties in the area. Therefore, the exception will not be materially detrimental to the public welfare or injurious to other properties in the territory in which the subject property is situated. Public Works is not averse to granting the exception as the applicant will be required to provide a drainage report to verify the adequacy of the downstream drainage system. If the receiving system is found to be inadequate the applicant shall be required to improve the system to make it adequate.

Please note that use of the term cultural resources includes both archaeological sites and historical buildings and/or structures. The review for possible historic-era building/structures, however, was limited to references currently in our office and should not be considered comprehensive. Project Description: Request approval of a Development Plan application to allow the development of a multifamily residential project on a vacant lot that includes a 2-story, 16 unit apartment building (8 units per story), and a parking lot with some carport parking. Previous Studies: XX This office has no record of any previous cultural resource studies for the proposed project area (see recommendation below). Archaeological and Native American Resources Recommendations: The proposed project area has the possibility of containing unrecorded archaeological site(s). A study is recommended prior to commencement of project activities. XX We recommend the lead agency contact the local Native American tribe(s) regarding traditional, cultural, and religious heritage values. For a complete listing of tribes in the vicinity of the project, please contact the Native American Heritage Commission at (916)373-3710. XX The proposed project area has a low possibility of containing unrecorded archaeological site(s). Therefore, no further study for archaeological resources is recommended. 391 Built Environment Recommendations: XX Since the Office of Historic Preservation has determined that any building or structure 45 years or older may be of historical value, if the project area contains such properties, it is recommended that prior to commencement of project activities, a qualified professional familiar with the architecture and history of Contra Costa County conduct a formal CEQA evaluation. Due to processing delays and other factors, not all of the historical resource reports and resource records that have been submitted to the Office of Historic Preservation are available via this records search. Additional information may be available through the federal, state, and local agencies that produced or paid for historical resource management work in the search area. Additionally, Native American tribes have historical resource information not in the California Historical Resources Information System (CHRIS) Inventory, and you should contact the California Native American Heritage Commission for information on local/regional tribal contacts. The California Office of Historic Preservation (OHP) contracts with the California Historical Resources Information System’s (CHRIS) regional Information Centers (ICs) to maintain information in the CHRIS inventory and make it available to local, state, and federal agencies, cultural resource professionals, Native American tribes, researchers, and the public. Recommendations made by IC coordinators or their staff regarding the interpretation and application of this information are advisory only. Such recommendations do not necessarily represent the evaluation or opinion of the State Historic Preservation Officer in carrying out the OHP’s regulatory authority under federal and state law. For your reference, a list of qualified professionals in California that meet the Secretary of the Interior’s Standards can be found at http://www.chrisinfo.org. If archaeological resources are encountered during the project, work in the immediate vicinity of the finds should be halted until a qualified archaeologist has evaluated the situation. If you have any questions please give us a call (707) 588-8455.

The purpose of this letter is to document existing conditions and evaluate the project’s potential transportation impacts and effect on traffic operations. Existing Conditions The study area includes a portion of Windhover Way along the project site frontage and the intersection of Pacheco Boulevard/Windhover Way in unincorporated Contra Costa County. Windhover Way is classified as a local road and has a north-south orientation. Along the project site’s frontage Windhover Way is 35 feet wide with two 10.5-foot travel lanes and parallel parking permitted on both sides. It has a prima facie speed limit of 25 mph. Windhover Way intersects with Pacheco Boulevard approximately 160 feet south of the proposed location for the project driveway. Pacheco Boulevard is classified as a Route of Regional Significance according to the Central County Action Plan (September 2017) and is oriented in the east-west direction. It has one travel lane and a bike lane in each direction together with a two-way left-turn lane. The posted speed limit is 45 mph. Parking is permitted on both sides where there is sufficient width. Turning movement counts at the intersection of Pacheco Boulevard and Windhover Way indicate that Pacheco Boulevard carries about 1,600 vehicles during the peak hour and Windhover Way serves about 25 vehicles during the peak hour. Project Description The proposed project would result in the construction of 24 new dwelling units on Assessor’s Parcel Number (APN) 380-220-066. The 24 units would be composed of 12 one-bedroom units and 12 two-bedroom units. Three of the units would be affordable, with two two-bedroom low-income units and one one-bedroom very low-income unit. The site is currently vacant and undeveloped. The project site would be primarily served by the proposed driveway located on Windhover Way approximately 160 feet north of Pacheco Boulevard. Trip Generation The anticipated trip generation for the proposed project was estimated using standard rates published by the Institute of Transportation Engineers (ITE) in Trip Generation Manual, 11th Edition, 2021 for “Multifamily Housing (Low-Rise)” (ITE LU #220). The site is currently undeveloped and therefore not generating any trips. For a conservative analysis, trip reductions resulting from nearby transportation options were not applied. Further reductions attributable to internal capture, pass-by or any other trip reductions are not applicable and therefore have also not been applied. The expected trip generation potential for the proposed project is indicated in Table 1. The proposed project is expected to generate an average of 162 trips per day, including 10 trips during the a.m. peak hour and 12 during the p.m. peak hour; these new trips represent the increase in traffic associated with the project. 399 Ms. Pamela West Page 2 September 6, 2022 Table 1 – Trip Generation Summary Land Use Units Daily AM Peak Hour PM Peak Hour Rate Trips Rate Trips In Out Rate Trips In Out Multifamily Housing (Low-Rise) 24 du 6.74 162 0.40 10 2 8 0.51 12 8 4 Note: du = dwelling unit Trip Distribution The pattern used to allocate new project trips to the street network was based on a review of turning movements at the study intersection and knowledge of local circulation patterns. The applied distribution assumptions and resulting trips are shown in Table 2. Table 2 – Trip Distribution Assumptions Route Percent Daily AM Trips PM Trips To/From the west via Pacheco Blvd 53% 86 5 6 To/From the east via Pacheco Blvd 47% 76 5 6 TOTAL 100% 162 10 12 Collision Analysis The collision history for the study intersection was reviewed to identify any trends or patterns that may indicate a potential safety issue. Collision rates were calculated based on records available from the California Highway Patrol as published in their Statewide Integrated Traffic Records System (SWITRS) reports. The most current five- year period available is from January 1, 2017, to December 31, 2021. The calculated collision rate for the intersection of Pacheco Boulevard/Windhover Way was compared to the average collision rate for similar facilities statewide, as indicated in 2018 Collision Data on California State Highways, California Department of Transportation (Caltrans). These average rates statewide are for intersections in the same environment (urban, suburban, or rural), with the same number of approaches (three or four), and the same controls (all-way stop, two-way stop, or traffic signal). Six collisions were documented at the study intersection between January 2017 and December 2021. This equates to a collision rate of 0.20 crashes per million vehicles entering the intersection (c/mve). The statewide average collision rate for four-legged stop-controlled intersections in urban settings is 0.14 c/mve and therefore the study intersection has a higher collision rate than the statewide average. Of the six collisions that occurred during the study period, three were rear-end, one was sideswipe, one was broadside, and one was a collision with an object. No clear trend can be gathered from the collision sample given the distribution of different types of collisions. Further, the injury rate at the intersection was 33.3 percent, substantially lower than the Statewide average of 46.2 percent. As a result, there is no clear safety concern at this time. Intersection Level of Service Methodologies Level of Service (LOS) is used to rate traffic operation on various types of facilities based on traffic volumes and roadway capacity using a series of letter designations ranging from A to F. Generally, Level of Service A represents 400 Ms. Pamela West Page 3 September 6, 2022 free flow conditions and Level of Service F represents forced flow or breakdown conditions. A unit of measure that indicates a level of delay generally accompanies the LOS designation. The study intersection was analyzed using the "Two-Way Stop-Controlled” (TWSC) unsignalized methodology published in the Highway Capacity Manual (HCM), Transportation Research Board, 2010. This source contains methodologies for various types of intersection control, all of which are related to a measurement of delay in average number of seconds per vehicle. The TWSC methodology determines a level of service for each minor turning movement by estimating the level of average delay in seconds per vehicle. Results are presented for individual movements together with the weighted overall average delay for the intersection. Traffic Operation Standards Contra Costa County established a Level of Service (LOS) Standard of LOS E for roadway segments and intersections along a Route of Regional Significance in the Contra Costa County Transportation Analysis Guidelines, 2020. This document states that development projects are required to address operational deficiencies where the addition of project traffic to an intersection along a Route of Regional Significance results in the degradation of intersection operations from an acceptable level (LOS E or better) to an unacceptable level (LOS F). Similarly, development projects are required to address operational deficiencies where the addition of project traffic increases the worst movement delay (for unsignalized intersections) by more than five seconds at intersections that are already operating at unacceptable levels. Short-Term Conditions The Existing Conditions scenario provides an evaluation of current operation based on existing traffic volumes during the weekday a.m. and p.m. peak periods. This condition does not include project-generated traffic volumes. Traffic volume data was collected on March 8, 2022, while local schools were operating with in-person learning and indicates that the study intersection is operating at an overall LOS A during both the a.m. and p.m. peak hours. However, the side street approach operates at LOS F and E during the a.m. and p.m. peak hours, respectively. Upon the addition of project-related traffic to the existing volumes, the study intersection is expected to continue operating at an overall LOS A and the side street approach is expected to continue operating at LOS E or F. Additional volume-based analysis was conducted since this unsignalized intersection is projected to operate at LOS F during the a.m. peak hour and the addition of project traffic would increase delay by more than five seconds. The peak hour volume warrant indicating a potential need for a traffic signal would not be satisfied under the Existing plus Project traffic volumes. It is noted that the nearby upstream traffic signal at Pacheco Boulevard/Camino Del Sol meters vehicle arrivals, which effectively creates gaps in the westbound traffic stream along Pacheco Boulevard. These gaps in the traffic stream occur with suitable frequency and create a situation where vehicles exiting from Windhover Way likely experienced less average delay than what is calculated using standard HCM methodologies. Therefore, it can be assumed that the average delay per vehicle reported using the HCM methodology is higher and more conservative than what may be experienced in the field. These results are summarized in Table 33. Copies of the traffic count data sheets and Level of Service calculations are enclosed. 401 Ms. Pamela West Page 4 September 6, 2022 Table 3 – Existing and Existing plus Project Peak Hour Intersection Levels of Service Study Intersection Approach Existing Conditions Existing plus Project AM Peak PM Peak AM Peak PM Peak Delay LOS Delay LOS Delay LOS Delay LOS Pacheco Blvd/Windhover Wy 1.6 A 0.6 A 2.1 A 0.8 A Southbound (Windhover Wy) Approach 60.3 F 36.2 E 68.5 F 40.2 E Notes: Delay is measured in average seconds per vehicle; LOS = Level of Service. Bold text = deficient operation Traffic Signal Warrant A traffic signal warrant analysis was conducted to determine the potential need for a traffic signal at the intersection of Pacheco Boulevard/Windhover Way based on a.m. and p.m. peak hour volumes under Existing plus Project Conditions. Chapter 4C of the California Manual on Uniform Traffic Control Devices (CA-MUTCD) provides guidance on when a traffic signal should be considered. For the purposes of this study only Warrant 3, the peak hour warrant, was considered. Warrant 3 is satisfied when an engineering study finds that the criteria in either of the following two categories are met: A. If all three of the following conditions exist for the same one hour (any four consecutive 15-minute periods) of an average day: 1. The total stopped time delay experienced by the traffic on one minor-street approach (one direction only) controlled by a STOP sign equals or exceeds: four vehicle-hours for a one-lane approach; or five vehicle-hours for a two-lane approach, and 2. The volume on the same minor-street approach (one direction only) equals or exceeds 100 vehicles per hour for one moving lane of traffic or 150 vehicles per hour for two moving lanes, and 3. The total entering volume serviced during the hour equals or exceeds 650 vehicles per hour for intersections with three approaches or 800 vehicles per hour for intersections with four or more approaches. B. The plotted point representing the vehicles per hour on the major street (total of both approaches) and the corresponding vehicles per hour on the higher-volume minor-street approach (one direction only) for one hour (any four consecutive 15-minute periods) of an average day falls above the applicable curve in Figure 4C-3 for the existing combination of approach lanes. The peak hour warrant would not be satisfied during either the a.m. or p.m. peak hours by the traffic volumes at the intersection of Pacheco Boulevard/Windhover Way. A copy of the Warrant 3 worksheet is enclosed. Finding – The study intersection is expected to continue operating at the same Level of Service upon the addition of project-generated traffic to Existing Conditions as without it. According to the analysis, the project would increase delay on the Windhover Way southbound approach to Pacheco Boulevard by more than five seconds during the a.m. peak hour, which is considered an adverse effect on traffic operations. However, the peak hour traffic signal warrant would not be satisfied for this intersection and this level of delay is common where minor local streets intersect a Route of Regional Significance. Additionally, the analysis does not account for the effect of the adjacent signalized intersection and its metering of traffic and creation of gaps in the traffic flow, which may result in a higher calculated average delay per vehicle than what may actually be experienced at the intersection. 402 Ms. Pamela West Page 5 September 6, 2022 Recommendation – While delay on the minor Windhover Way approach to Pacheco Boulevard would be expected to increase by more than five seconds due to the project, the peak hour volumes on the stop-controlled approach would be insufficient to warrant signalization, and as this project would develop the last vacant parcel feeding into the intersection, volumes would not ever be expected to reach the level needed to warrant signalization. Given the lack of a safety concern that could be addressed through right-of-way controls and the low volumes, no further action is recommended. Site Circulation and Access Vehicular Site Access The proposed project includes a new driveway on Windhover Way located approximately 160 feet north of the intersection with Pacheco Boulevard. Both left and right turns would be permitted at the proposed driveway. Vehicular Sight Distance At driveways a substantially clear line of sight should be maintained between the driver of a vehicle waiting at the crossroad and the driver of an approaching vehicle. Adequate time must be provided for the waiting vehicle to either cross, turn left, or turn right, without requiring the through traffic to radically alter their speed. Sight distance along Windhover Way at the proposed project driveway was evaluated based on sight distance criteria contained in the Highway Design Manual published by Caltrans. The recommended sight distances for driveways are based on stopping sight distance, which uses the approach travel speeds as the basis for determining the recommended sight distance. Based on the prima facie speed of 25 mph along Windhover Way, the minimum stopping sight distance needed is 150 feet. Sight distances at the proposed driveway location were field measured so include consideration for the vegetation and topography along Windhover Way. The available sight distance at the proposed driveway along Windhover Way exceeds 150 feet in each direction. However, parked vehicles adjacent to the driveway opening would limit sight lines to less than the required 150 feet. Therefore, parking should be prohibited within 20 feet of both sides of the driveway to preserve adequate sight lines. Sight distance was also field measured at the southbound Windhover Way approach to the intersection with Pacheco Boulevard. At side-street approaches, the recommended sight distances are based on corner sight distance as published by Caltrans in the Highway Design Manual. To establish the critical 85th percentile speed for vehicles traveling on Pacheco Boulevard, a spot speed survey was conducted in the field. Vehicles were observed to have a critical speed of approximately 40 mph in both directions. Therefore, the required sight distance along Pacheco Boulevard is 385 feet to the east and 445 feet to the west for drivers exiting from Windhover Way. A copy of the speed survey is enclosed. The sight lines from Windhover Way were observed to be obstructed to the west by parked vehicles along the north side of Pacheco Boulevard. With the existing parking configurations, sight distance was field measured to be approximately 350 feet to the west, which is less than the minimum corner sight distance required in the Highway Design Manual. To the east, sight distance was field measured in excess of 385 feet and is therefore considered adequate. To achieve adequate sight distance, parking prohibitions along the north side of Pacheco Boulevard within 20 feet west of the intersection are recommended. Finding – Sight distances along Windhover Way at the proposed driveway are inadequate for the prima facie speed of 25 mph due to parking adjacent to the driveway location. Similarly, sight lines are also inadequate at the Windhover Way approach to Pacheco Boulevard to the west for the observed 85th percentile speed of 40 mph due to adjacent parking. 403 Ms. Pamela West Page 6 September 6, 2022 Recommendation – To achieve adequate sight lines at the project driveway, parking should be prohibited within 20 feet of the proposed driveway to ensure that adequate sight lines are maintained. On Pacheco Boulevard, it is recommended that parking restrictions within 20 feet west of the intersection with Windhover Way implemented to provide adequate sight lines at the Windhover Way approach. Vehicle Miles Traveled (VMT) Evaluation Consideration was given to the project’s potential generation of Vehicle Miles Traveled (VMT). The Contra Costa County Public Works Department adopted a VMT policy on June 23, 2020, in their document Transportation Analysis Guidelines. Guidance provided in this document recommends the use of screening thresholds to identify when a proposed project is presumed to result in a less-than-significant impact without conducting a detailed study. According to the Contra Costa County Travel Demand Model estimates, the Countywide home-based average VMT per resident is 19.4 miles. Concurring with guidance provided by this document, a project located anywhere in the County which generates a VMT that is 15-percent or more below this value, or 16.5 miles per resident, should be expected to cause a less-than-significant VMT impact and would not require further VMT analysis. The project would be located within Traffic Analysis Zone (TAZ) 20034 of the Contra Costa Travel Demand Model which has a home-based VMT of 16.0 miles per resident. Because this per capita VMT rate of 16.0 is lower than the significance threshold of 16.5 miles, the project is presumed to have a less-than-significant VMT impact and does not require further VMT analysis. Further, adjacent TAZs west of I-680, including 20033 and 20038, also have a per capita VMT rate that is less than the significance threshold so are consistent with TAZ 20034. A summary of the VMT findings is provided in Table 4. Table 4 – Vehicle Miles Traveled Analysis Summary VMT Metric Baseline VMT Rate Significance Threshold Project VMT Rate Resulting Significance Residential VMT per Capita (Countywide Baseline) 19.4 16.5 16.0 Less-Than-Significant Note: VMT Rate is measured in VMT per Capita, or the number of daily miles driven per resident Finding – The project would be expected to have a VMT per capita less than 15-percent below the countywide VMT per resident. Therefore, the project is presumed to have a less-than-significant VMT impact. Alternative Modes Pedestrian Facilities A network of sidewalks, crosswalks and curb ramps are generally provided along Windhover Way and Pacheco Boulevard within the study area. Project Summary – Internal pedestrian access within the site is provided via a network of sidewalks, curb ramps, and pathways. The project would also provide new sidewalks on the western side of the project driveway, connecting to the existing sidewalk on Windhover Way. All pedestrian facilities are presumed to be built to satisfy current Contra Costa County Public Works Department standards. Finding – Existing and proposed pedestrian facilities serving the project site would be adequate. 404 Ms. Pamela West Page 7 September 6, 2022 Bicycle Network A northbound Class II bike lane exists on Pacheco Boulevard within the study area. Bicyclists ride in the roadway and/or on sidewalks along all other streets within the project Study Area. Project Summary – The project does not propose to modify or construct new bicycle facilities within the study area. Finding – Existing bicycle facilities serving the project site would be adequate. Transit Facilities Development sites which are located within a one-half mile walk of a transit stop are generally considered to be adequately served by transit. County Connection County Connection provides fixed route bus service in Contra Costa County. Two bicycles can be carried on most buses. Bike rack space is on a first come, first served basis. Additional bicycles are allowed on buses at the discretion of the driver. The County Connection provides bus service to the immediate study area via four local routes. Line 18 provides weekday service between the Martinez Amtrak station and Pleasant Hill BART Station, via Pacheco Boulevard and Morello Avenue. Service is provided between 6:00 a.m. and 9:30 p.m. with an approximately 80-minute headway. The bus stop nearest the project site is near the intersection of Morello Avenue/Pacheco Boulevard, approximately one-quarter mile from the project site. Line 19 provides weekday service between the Martinez Amtrak station and Diablo Valley College via Pacheco Boulevard. Service is provided between 6:00 a.m. and 9:00 p.m. with 55-minute headways during the peak period and 110-minute headways during off-peak periods. The bus stop closest to the project site is near 4001 Pacheco Boulevard, approximately 0.1 mile from the project site. Line 99x provides peak period weekday service between the Martinez Amtrak Station and the North Concord BART Station via Pacheco Boulevard. On weekdays, service is provided from 6:00 a.m. to 9:00 a.m. and from 3:30 p.m. to 6:30 p.m. with a bus arriving every 20 to 30 minutes. The bus stop closest to the project site is near the intersection of Morello Avenue/Pacheco Boulevard, approximately one-quarter mile from the project site. Line 316 provides weekend service between the Martinez Amtrak Station and the Pleasant Hill BART Station via Pacheco Boulevard. Weekend service is provided between 7:30 a.m. and 8:00 p.m. with headways of 80 minutes. The closest bus stop to the project site is near the intersection of Morello Avenue/Pacheco Boulevard, approximately one-quarter mile from the project site. Amtrak Amtrak is a passenger railroad service that provides medium- and long-distance service between cities in the United States and Canada, with a station in Martinez approximately three miles from the project site at 601 Marina Vista Road. The Martinez Amtrak Station is served by the Capitol Corridor, California Zephyr, Coast Starlight, and San Joaquin passenger train services. Bay Area Rapid Transit (BART) The BART system provides regional rail service between San Mateo, San Francisco, Alameda, Contra Costa, and Santa Clara counties. The nearest BART station is the North Concord BART Station at 3700 Port Chicago Highway, which is approximately six miles from the project site. This station is served by the Antioch, Pittsburg, and San Francisco International Airport lines. On weekdays during peak commute periods trains have a 15-minute 405 Ms. Pamela West Page 8 September 6, 2022 headway. During all other times (off-peak periods and weekends), trains operate at 20-minute headways. Typical hours of operation for BART are between the hours of 5:00 a.m. and midnight during the weekday, 6:00 a.m. to midnight on Saturdays and 8:00 a.m. to midnight on Sundays. County Connection LINK Dial-a-ride, also known as paratransit, or door-to-door service, is available for those who are unable to independently use the transit system due to a physical or mental disability. The study area is served by the County Connection LINK that offers paratransit services. This service is designed to serve the needs of individuals with disabilities within Contra Costa County. On-Demand Transportation Services On-demand private vehicle services (e.g., taxi, Uber, Lyft, etc.) are available in Contra Costa County 24 hours a day. These vehicles can be used for trips within Contra Costa County and adjacent destinations. Project Summary – If 20 percent of peak hour trips were made by transit, there would be two and three additional transit riders during the a.m. and p.m. peak hours respectively, spread out over multiple routes and times. The volume of riders expected to be generated by the project would therefore be unlikely to exceed the carrying capacity of the existing bus service near the project site, especially when spread over several routes and times. Finding – The project site is adequately served by transit since there are existing transit stops within one-half mile and numerous routes and travel options. Parking Facilities The project was analyzed to determine whether the proposed parking supply would be enough to satisfy the County Code requirements for developments that fall under the M-29 (Multiple Family Residential District) zoning. The Contra Costa County Municipal Code, Article 84-26.12 Off-street parking requirements state that one and one- half off-street parking spaces shall be provided for each one-bedroom unit, and two spaces shall be provided for each two-bedroom unit. Additional guest parking spaces are also required at a rate of one-quarter space per unit. As there are 12 one-bedroom units and 12 two-bedroom units proposed, the project should provide at least 48 parking spaces based on County Code requirements. Table 5 summarizes the County’s parking requirements as they apply to the proposed project. Table 5 – County Parking Requirement Summary Unit Description Parking Requirement Number of Units Required Number of Parking Spaces One-Bedroom 1.5 parking spaces per unit 12 18 Two-Bedroom 2 parking spaces per unit 12 24 All Units 0.25 guest parking spaces per unit 24 6 TOTAL 48 Note: Parking Requirements per Contra Costa Municipal Code Article 84-26.12 However, California Government Code Chapter 4.3 Density Bonuses and Other Incentives §65915(p).3 states that a city or county shall not impose vehicular parking standards if the development is located within one-half mile of a major transit stop. Given that County Connection transit stops are within one-half mile of the project site as detailed previously, the on-site parking required by the project shall not be governed by County Code requirements. Instead, the project is permitted to meet the minimum requirements as specified by California 406 Ms. Pamela West Page 9 September 6, 2022 Government Code. Section 65915(o).6 of the California Government Code defines the total number of units as the number of units less those added by a density bonus. For this project, two of the units would be added by a density bonus. Further, parking requirements under §65915(p) require one parking space for every zero-bedroom or one- bedroom unit, and one and one-half parking spaces for every two or three-bedroom unit where a development provides affordable housing. Requirements for guest parking and parking for those with disabilities are specifically excluded under that same section. Based on these two Code sections, the project is required to provide at least 28 parking spaces, as summarized in Table 6. Table 6 – State Parking Requirement Summary Unit Description Parking Requirement Number of Units Required Number of Parking Spaces Density Bonus 0 parking spaces per unit 2 0 One-Bedroom 1 parking space per unit 11 11 Two-Bedroom 1.5 parking spaces per unit 11 17 TOTAL 24 28 Note: Parking Requirements per California Government Code Section 4.3 The site plan shows that 33 parking spaces would be provided. Based on California Government Code parking requirements, the proposed project provides more than the minimum number of parking spaces required to meet the state’s requirements. The projected parking demand was also estimated using standard rates published by ITE in Parking Generation, 5th Edition, 2019 for “Multifamily Housing (Low-Rise)” (ITE LU #220). According to the ITE estimates, 25 parking spaces would be required to accommodate the expected demand. Finding – The proposed parking supply of 33 spaces would not satisfy the County’s Code requirement of 48 spaces; however, it would exceed the minimum of 28 required parking spaces per California Government Code requirements and the anticipated parking demand of 25 spaces per the ITE Parking Generation Manual, 5th Edition, 2019. Electric Vehicle Parking Contra Costa County outlines specific electric vehicle (EV) parking requirements for multifamily residential projects. The Contra Costa Municipal Code Section 4.106.4.2 New Multifamily Dwellings of Article 74-4.006 states that ten percent of the on-site parking shall be EV charging spaces. At least half of the EV spaces shall be equipped with fully operational EV supply equipment of at least Level Two. The remaining EV parking spaces shall be capable of supporting future EV supply equipment. Since 33 parking spaces are proposed as part of the project, at least four spaces are required to be EV parking spaces. Of the four spaces, two must be equipped with Level Two EV supply equipment. The project would include four EV spaces with two having fully operational Level Two EV supply equipment, satisfying the County’s requirement for EV parking. Additionally, the project would also provide a number of “pre plumbed” conduits with supportive infrastructure for future EV use as needed. Finding – The project would include four EV parking spaces, of which two would include fully operational Level Two EV supply equipment. This meets the minimum requirements set forth by the County, and therefore the proposed EV parking is adequate. 407 Ms. Pamela West Page 10 September 6, 2022 Bicycle Parking Article 82-16.412, Bicycle Parking, of the Contra Costa County Municipal Code states that one long-term bicycle storage facility shall be provided for approximately every seven bedrooms (15 percent) and one short-term bicycle storage facility shall be provided for every 20 bedrooms (5 percent). Since 36 bedrooms are being proposed, the project is required to provide at least six long-term bicycle storage spaces and at least two short-term bicycle storage spaces. As part of the project, six long-term bicycle storage lockers would be provided as well as two short- term bicycle storage spaces. Therefore, the proposed project provides enough bicycle storage facilities to meet the County’s requirements. Finding – Proposed bicycle storage facilities exceed the minimum number of long-term and short-term requirements set by the County. Transportation Demand Management (TDM) Plan The following section describes the proposed TDM plan prepared in accordance with Chapter 82-32 of the Contra Costa County Municipal Code. A separate, more detailed TDM plan document will be prepared and submitted for County review as well. It should be noted that the project’s density (i.e., dwelling units per acre) and presence of affordable housing also reduce vehicle trips and vehicle miles traveled (VMT) but are not included here as they are considered inherent to the development. Education, Outreach & Marketing The HOA management company will provide customized transportation information to the community’s residents when a unit is leased or offered for rent. This information should be available in print and virtual format and should include elements such as:  County Connection bus and BART timetables;  The locations of the nearest bus and BART stops;   Information regarding transit passes;  Promotion of the 511 Contra Costa incentive programs;   Directions to and information on the Pacheco Transit Center;   Biking and walking maps, including highlighting existing and new pedestrian connections to key destinations;    Bike parking locations and instructions for proper use; and   Bicycle safety training literature with information on local bike safety/training programs. This information should be maintained in a readily accessible location for this community even though a resident may also locate this information on their own through various online sources. Implementation of an educational program dedicated to outreach and marketing as described above would result in an estimated reduction in VMT of 0.9-percent according to Quantifying Greenhouse Gas Mitigation Measures, California Air Pollution Control Officers Association (CAPCOA), 2010. Finding – Implementation of the Transportation Demand Management program as described above and as required under County Code would result in an estimated VMT reduction of 0.9 percent. Conclusions and Recommendations  The proposed project would generate an average of 162 net-new daily trips, including 10 new trips during the a.m. peak hour and 12 new trips during the p.m. peak hour. 408 Ms. Pamela West Page 11 September 6, 2022  The study intersection of Pacheco Boulevard and Windhover Way has a higher collision rate than the statewide average for similar facilities. However, as the injury rate was substantially lower than the statewide average, no remedial action is recommended.  The study intersection is expected to continue operating at the same Levels of Service with and without the project.  The peak hour traffic signal warrant is not satisfied for the unsignalized intersection of Pacheco Boulevard/Windhover Way under all conditions with and without the project. Given the low volume and lack of a demonstrated safety concern that could be addressed through signalization, no improvements are recommended.  The sight distances at the proposed new driveway access on Windhover Way and at the Windhover Way approach to Pacheco Boulevard are inadequate due to adjacent parking. To achieve adequate sight lines, it is recommended that parking be prohibited within 20 feet of both sides of the proposed project driveway, and within approximately 20 feet west of the Windhover Way approach to Pacheco Boulevard.  The proposed project would have a less-than-significant transportation impact on Vehicle Miles Traveled.  Pedestrian, bicycle, and transit facilities would be adequate to serve the project as proposed.  The proposed project would provide a parking supply of 33 spaces which is greater than what is required under the California Government Code and greater than the estimated demand based on standard ITE rates; however, it is less than the required parking per the County Code.  The proposed project would meet County Code requirements regarding EV parking since four EV spaces would be included, with two spaces having fully operational Level Two EV supply equipment.  The number of short- and long-term bicycle parking spaces proposed (two and six, respectively) would be greater than the County’s requirement for these types of bicycle storage facilities.  Implementation of the Transportation Demand Management program as proposed and as required under County Code would result in an estimated VMT reduction of 0.9 percent.

HortScience | Bartlett Consulting, Divisions of The F. A. Bartlett Tree Expert Company, was asked to prepare an Arborist Report for the trees within the project area as part of the application to Contra Costa County. This report responds to that request. Description of Trees I visited the site on December 21, 2021. Nine (9) trees representing seven (7) species were evaluated (Table 1), tagged as #35 - 43. All but one of the species were represented by a single tree. Trees assessed were typical of the area; California black walnut #37 and coast redwood #39 are native to California. Two of the trees assessed (#39 and #43) were off-site. Overall, five of the trees were in poor condition, three were in fair condition, and one (off-site coast redwood #39) was in good condition. Descriptions of each tree are found in the Tree Assessment, and approximate locations are plotted on the Tree Assessment Map (see Exhibits). Table 1.

It had multiple branch attachments and a vase-shaped crown (Photo 1).  Carolina cherry laurel #36 was a shrubby tree with stems ranging from 4 to 16 inches arising from its base. It was in poor condition with extensive branch dieback.  California black walnut #37 was growing at the east fence. It had stems of 3 and 8 inches at about 3 ft. above grade and was in poor condition with defective structure.  Glossy privet #38 was nearby, in shrub form. It had multiple stem attachments from 2 to 4 inches in diameter and was in poor condition.  Off-site coast redwood #39 was the largest tree assessed, with a diameter of 27 inches (Photo 2). It was in good condition, with form and structure typical of the species.  Olives #40, 41 and 42 had multiple stems rising from their bases with stem diameters ranging from 5 to 11 inches (Photo 2). Condition ranged from fair (#40 and 41) to poor (#43). The olives had a history of limb removal, and were growing close to the north property fence. Photo 1 (left). London plane #35 was growing near the southeast corner of the site. Photo 3. Off-site Siberian elm #43 was growing near Windhover Way. Photo 2. Off-site coast redwood (red arrow) and olives #42 – 40 (L to R, yellow arrows) were growing at the north end of the property. 418 Arborist Report. 0 Pacheco Blvd. Martinez, CA.

Bartlett Tree Expert Company 325 Ray St. Pleasanton, CA ● 925.484.0211 ● www.hortscience.com  Off-site Siberian elm #43 was growing near the sidewalk on Windhover Way. It was 16 inches in diameter and had codominant trunks. The elm had been repeatedly pruned back from a nearby light pole and was in poor condition (Photo 3). On properties in unincorporated areas, Contra Costa County protects certain indigenous tree species with a trunk diameter of 6.5 inches or greater. Based on this definition, California black walnut #37 and coast redwood #39 were considered Protected. Protected trees cannot be removed nor can construction occur within their driplines without a permit. Protected status of individual trees is identified in the Tree Assessment (see Exhibits). 419 Arborist Report. Windhover Way. Martinez, CA. Page 4 January 2022 HortScience│Bartlett Consulting ● Divisions of The F.A. Bartlett Tree Expert Company 325 Ray St. Pleasanton, CA ● 925.484.0211 ● www.hortscience.com Suitability for Preservation Before evaluating the impacts that will occur during development, it is important to consider the quality of the tree resource itself, and the potential for individual trees to function well over an extended length of time. 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. 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, coast redwood is tolerant of construction impacts if properly irrigated, while California black walnut is intolerant 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.  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 (http://www.cal-ipc.org/paf/) lists species identified as being invasive. Martinez is part of the Central West Floristic Province. Glossy privet and olive are listed as having limited invasiveness potential. Species with limited invasiveness potential are invasive but their ecological impacts are minor on a statewide level or there was not enough information to justify a higher score. Each tree was rated for suitability for preservation based upon its age, health, structural condition and ability to safely coexist within a development environment. Suitability ratings are provided for each tree in the Tree Assessment Forms (see Exhibits). Table 1: Tree Suitability for Preservation Windhover Way. Martinez, CA. High These are trees with good health and structural stability that have the potential for longevity at the site. Off-site coast redwood #39 had high suitability for preservation. Moderate Trees in this category have fair health and/or 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. Olives #40 and 41 and London plane #35 had moderate suitability for preservation. 420 Arborist Report. 0 Pacheco Blvd. Martinez, CA. Page 5 January 2022 HortScience│Bartlett Consulting ● Divisions of The F.A. Bartlett Tree Expert Company 325 Ray St. Pleasanton, CA ● 925.484.0211 ● www.hortscience.com Low Trees in this category are in poor health or have 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. Five trees had low suitability for preservation: Carolina cherry laurel #36, California black walnut #37, glossy privet #38, olive #42, and off-site Siberian elm #43. We consider trees with high suitability for preservation to be the best candidates for preservation. We do not 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 Appropriate tree retention requires a practical match between the location and intensity of construction activities and the quality and health of the trees. The Tree Assessment was the reference point for tree condition and quality. I used the Topographic Survey of Parcel C (Sousa Land Surveys, 7/22/2019) and the Gulway Apartments Site, Paving, and Horizontal Control Plan (Architectural Concepts, 10/8/2019) to determine the project area and evaluate impacts to trees. The plans propose construction of a two-story multi-residential building of approximately 7,470 square feet. A new driveway from Windhover Way and parking areas will be built around it, with new trees and landscaping planned along the perimeters. The site will be intensely re-developed from property line to property line and potential impacts to trees will be severe. Eight (8) trees will be removed (#35 – 38 and 40 – 42, as well as off-site tree #43, which appears to be within the limits of grading at the road). Of these trees, California black walnut #37 is Protected. Off-site redwood #39 will remain; this tree is also Protected. Due to its proximity to the property, the redwood may be impacted by grading and construction activities. Based on my assessment of the plans and evaluation of the trees, I recommend preservation of off-site redwood #39, provided recommendations included in the Tree Preservation Guidelines (following page) can be followed. Tree Preservation Guidelines The goal of tree preservation is not merely tree survival during development but maintenance of tree health and beauty for many years. Retained trees that are either subject to extensive injury during construction or are inadequately maintained become a liability rather than an asset. The response of individual trees will depend on the amount of excavation and grading and the construction methods. The following recommendations will help reduce impacts to trees from development and maintain and improve their health and vitality through the clearing, grading and construction phases. 421 Arborist Report. 0 Pacheco Blvd. Martinez, CA.

Where possible, include the location of all trees within 10 feet of the project limit. Include trunk locations on all project plans. 2. The project’s perimeter security fence will also serve as the TREE PROTECTION ZONE. No grading, excavation, construction or storage of materials should occur outside the project limit. 3. All plans affecting trees shall be reviewed by the Consulting Arborist with regard to tree impacts. These include, but are not limited to, demolition plans, grading plans, drainage plans, utility plans, and landscape and irrigation plans. 4. Irrigation systems must be designed so that no trenching severs roots larger than 2 in. in diameter will occur within the TREE PROTECTION ZONE. 5. Any herbicides placed under paving materials must be safe for use around trees and labeled for that use. Pre-construction treatments and recommendations 1. The project’s perimeter security fence will also serve as the TREE PROTECTION ZONE. No grading, excavation, construction or storage of materials should occur outside the project limit. 2. Off-site trees to be preserved may require pruning to provide clearance for demolition, grading and construction. Tree care firm providing the pruning shall be a State of California Licensed Tree Contractor (C61/D49). All pruning shall be done by Certified Arborist or Certified Tree Worker in accordance with the latest edition of the Best Management Practices for Pruning (International Society of Arboriculture) and the American National Standard for Tree Care Operations (Z133.1) and Pruning (A300). 3. Tree(s) to be removed that have branches extending into the canopy of tree(s) to remain shall be removed by a Certified Arborist or Certified Tree Worker and not by the demolition contractor. The Certified Arborist or Certified Tree Worker shall remove the trees in a manner that causes no damage to the tree(s) and understory to remain. 4. Trees to be removed shall be felled so as to fall away from TREE PROTECTION ZONE and avoid pulling and breaking of roots of off-site trees to remain. If roots are entwined, the Consulting Arborist may require first severing the major woody root mass before extracting the trees. 5. All tree work shall comply with the Migratory Bird Treaty Act as well as California Fish and Wildlife code 3503-3513 to not disturb nesting birds. To the extent feasible tree pruning and removal should be scheduled outside of the breeding season. Breeding bird surveys should be conducted prior to tree work. Qualified biologists should be involved in establishing work buffers for active nests. Recommendations for tree protection during construction 1. Any approved grading, construction, demolition or other work within 5 ft. of the Tree Protection Zone near tree #39 should be monitored by the Consulting Arborist. 422 Arborist Report. 0 Pacheco Blvd. Martinez, CA.

Any root pruning that will occur within 5 ft. of the Tree Protection Zone near tree #39 shall receive the prior approval of and may be supervised by the Consulting Arborist. Roots should be cut with a saw to provide a flat and smooth cut. Removal of roots larger than 2” in diameter should be avoided. 3. If roots 2” and greater in diameter are encountered during site work and must be cut to complete the construction, the Consulting Arborist must be consulted to evaluate effects on the health and stability of the tree and recommend treatment. 4. 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.

Thill Principal Consultant 429 E. Cotati Avenue Cotati, CA 94931 (707) 794-0400 Project: 22-058 439 1 INTRODUCTION This report summarizes the results of the noise assessment prepared for the Windhover Terrace Apartments project in Martinez, California. The analysis evaluates the compatibility of the proposed project with respect to the noise levels resulting from vehicular traffic along Pacheco Boulevard and other roadways serving the site. The report presents background information on environmental noise and definitions of the technical terms used in the assessment, the applicable regulatory criteria used in the assessment, a summary of existing noise levels, and our evaluation of the compatibility of the proposed project with the noise environment at the project site. Noise reduction measures are presented to provide an acceptable interior noise environment per City of Martinez guidelines and State Building Code requirements. SETTING Fundamentals of Environmental Noise Noise may be defined as unwanted sound. Noise is usually objectionable because it is disturbing or annoying. The objectionable nature of sound could be caused by its pitch or its loudness. Pitch is the height or depth of a tone or sound, depending on the relative rapidity (frequency) of the vibrations by which it is produced. Higher pitched signals sound louder to humans than sounds with a lower pitch. Loudness is intensity of sound waves combined with the reception characteristics of the ear. Intensity may be compared with the height of an ocean wave in that it is a measure of the amplitude of the sound wave. In addition to the concepts of pitch and loudness, there are several noise measurement scales which are used to describe noise in a particular location. A decibel (dB) is a unit of measurement which indicates the relative amplitude of a sound. The zero on the decibel scale is based on the lowest sound level that the healthy, unimpaired human ear can detect. Sound levels in decibels are calculated on a logarithmic basis. An increase of 10 decibels represents a ten-fold increase in acoustic energy, while 20 decibels is 100 times more intense, 30 decibels is 1,000 times more intense, etc. There is a relationship between the subjective noisiness or loudness of a sound and its intensity. Each 10 decibel increase in sound level is perceived as approximately a doubling of loudness over a fairly wide range of intensities. Technical terms are defined in Table 1. There are several methods of characterizing sound. The most common in California is the A- weighted sound level (dBA). This scale gives greater weight to the frequencies of sound to which the human ear is most sensitive. Representative outdoor and indoor noise levels in units of dBA are shown in Table 2. Because sound levels can vary markedly over a short period of time, a method for describing either the average character of the sound or the statistical behavior of the variations must be utilized. Most commonly, environmental sounds are described in terms of an average level that has the same acoustical energy as the summation of all the time-varying events. This energy-equivalent sound/noise descriptor is called Leq. The most common averaging period is hourly, but Leq can describe any series of noise events of arbitrary duration. 440 2 The scientific instrument used to measure noise is the sound level meter. Sound level meters can accurately measure environmental noise levels to within about plus or minus 1 dBA. Various computer models are used to predict environmental noise levels from sources, such as roadways and airports. The accuracy of the predicted models depends upon the distance the receptor is from the noise source. Close to the noise source, the models are accurate to within about plus or minus 1 to 2 dBA. Since the sensitivity to noise increases during the evening and at night -- because excessive noise interferes with the ability to sleep -- 24-hour descriptors have been developed that incorporate artificial noise penalties added to quiet-time noise events. The Community Noise Equivalent Level (CNEL) is a measure of the cumulative noise exposure in a community, with a 5 dB penalty added to evening (7:00 pm - 10:00 pm) and a 10 dB addition to nocturnal (10:00 pm - 7:00 am) noise levels. The Day/Night Average Sound Level (DNL or Ldn) is essentially the same as CNEL, with the exception that the evening time period is dropped and all occurrences during this three-hour period are grouped into the daytime period. Effects of Noise The thresholds for speech interference indoors are about 45 dBA if the noise is steady and above 55 dBA if the noise is fluctuating. Outdoors the thresholds are about 15 dBA higher. Steady noises of sufficient intensity (above 35 dBA) and fluctuating noise levels above about 45 dBA have been shown to affect sleep. Interior residential standards for multi-family dwellings are set by the State of California at 45 dBA Ldn. Typically, the highest steady traffic noise level during the daytime is about equal to the Ldn and nighttime levels are 10 dB lower. The standard is designed for sleep and speech protection and most jurisdictions apply the same criterion for all residential uses. Typical structural attenuation is 12 to 17 dB with open windows. With standard construction and closed windows in good condition, the noise attenuation factor is around 20 dB for an older structure and 25 dB for a newer dwelling. Sleep and speech interference is therefore of concern when exterior noise levels are about 57 to 62 dBA Ldn with open windows and 65 to 70 dBA Ldn if the windows are closed. Levels of 55 to 60 dBA are common along collector streets and secondary arterials, while 65 to 70 dBA is a typical value for a primary/major arterial. Levels of 75 to 80 dBA are normal noise levels at the first row of development outside a freeway right-of-way. In order to achieve an acceptable interior noise environment, bedrooms facing secondary roadways need to be able to have their windows closed, those facing major roadways and freeways typically need special glass windows. 441 3 TABLE 1 Definition of Acoustical Terms Used in this Report Term Definition Decibel, dB A unit describing, the amplitude of sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure. The reference pressure for air is 20 micro Pascals. Sound Pressure Level Sound pressure is the sound force per unit area, usually expressed in micro Pascals (or 20 micro Newtons per square meter), where 1 Pascal is the pressure resulting from a force of 1 Newton exerted over an area of 1 square meter. The sound pressure level is expressed in decibels as 20 times the logarithm to the base 10 of the ratio between the pressures exerted by the sound to a reference sound pressure (e. g., 20 micro Pascals). Sound pressure level is the quantity that is directly measured by a sound level meter. Frequency, Hz The number of complete pressure fluctuations per second above and below atmospheric pressure. Normal human hearing is between 20 Hz and 20,000 Hz. Infrasonic sound are below 20 Hz and Ultrasonic sounds are above 20,000 Hz. A-Weighted Sound Level, dBA The sound pressure level in decibels as measured on a sound level meter using the A-weighting filter network. The A-weighting filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the frequency response of the human ear and correlates well with subjective reactions to noise. Equivalent Noise Level, Leq The average A-weighted noise level during the measurement period. Lmax, Lmin The maximum and minimum A-weighted noise level during the measurement period. L01, L10, L50, L90 The A-weighted noise levels that are exceeded 1%, 10%, 50%, and 90% of the time during the measurement period. Day/Night Noise Level, DNL or Ldn The average A-weighted noise level during a 24-hour day, obtained after addition of 10 decibels to levels measured in the night between 10:00 pm and 7:00 am. Community Noise Equivalent Level, CNEL The average A-weighted noise level during a 24-hour day, obtained after addition of 5 decibels in the evening from 7:00 pm to 10:00 pm and after addition of 10 decibels to sound levels measured in the night between 10:00 pm and 7:00 am. Ambient Noise Level The composite of noise from all sources near and far. The normal or existing level of environmental noise at a given location. Intrusive That noise which intrudes over and above the existing ambient noise at a given location. The relative intrusiveness of a sound depends upon its amplitude, duration, frequency, and time of occurrence and tonal or informational content as well as the prevailing ambient noise level.

The current version of the California Building Code (CBC) requires interior noise levels attributable to exterior environmental noise sources to be limited to a level not exceeding 45 dBA Ldn/CNEL in any habitable room. City of Martinez 1985 Noise Element of the General Plan.1 The Noise Element of the City of Martinez General Plan establishes standards for noise and land use compatibility for new residential land uses. These standards consider noise levels of 60 dBA Ldn or less normally acceptable provided that buildings are of normal conventional construction, without any special noise insulation requirements. where the exterior noise exposure is between 60 dBA and 70 dBA Ldn residential use is considered ‘conditionally acceptable’ such that new construction should be undertaken only after detailed analysis of the noise reduction requirements and needed noise insulation features included in the design. Interior noise levels of 45 dBA Ldn or less are considered normally acceptable. Existing Noise Environment A noise monitoring survey was conducted to quantify the existing noise environment at the site between Wednesday, April 27, 2022 and Friday, April 29, 2022. The noise monitoring survey included two long-term noise measurements (LT-1 and LT-2) and three short-term noise measurements (ST-1, ST-2, and ST-3), as showing in Figure 1. All noise measurements were conducted with Larson Davis Laboratories Model LxT1 Sound Level Meters fitted with ½-inch pre-polarized condenser microphones and windscreens. The meters were calibrated with a Larson Davis Model CAL200 precision acoustic calibrator prior to and following the measurement survey. The internal clocks of the sound level meters were synchronized to ensure both identical sound level response and simultaneous operation. The noise monitor at location LT-1 was positioned at a height of 12 feet above the existing grade on a tree along the west boundary of the site. Vehicular traffic on Pacheco Boulevard and Windhover Way was the predominant noise source affecting the site. The measured noise levels at this location, including the energy equivalent noise level (Leq), maximum (Lmax), minimum (Lmin), and the noise levels exceeded 1, 10, 50 and 90 percent of the time (indicated as L1, L10, L50 and L90) are shown on Figures 2-4. A review of the data indicates that the noise levels at site LT- 1 follow a diurnal pattern characteristic of traffic noise, with the average daytime noise levels ranging from 54 to 66 dBA Leq and the average nighttime hourly noise levels ranging from 50 to 357 dBA Leq. The Day/Night Noise Level during on April 28, 2022 was 62 dBA Ldn. The noise monitor at location LT-2 was also positioned at a height of 12 feet above the existing grade on a tree along the north boundary of the site. Distant vehicular traffic was the predominant noise source affecting the site, with average daytime noise levels ranging from 49 to 57 dBA Leq and the average nighttime hourly noise levels ranging from 48 to 53 dBA Leq. The Day/Night 1 The City of Martinez in currently updating its General Plan Noise Element. The updated plan has not yet been adopted. As a result, the current noise standards and policies, adopted in November 1985 are used in this document. 444 6 Noise Level during on April 28, 2022 was 58 dBA Ldn. The measured noise levels at this location are shown on Figures 5-7. A series of short-term noise measurements were made concurrently with the long-term measurements at LT-1 and LT-2 on the morning of Wednesday, April 27, 2022. Traffic along Pacheco Boulevard was the predominant noise source at these locations. Table 3 summarizes the noise measurement results at ST-1, ST-2, and ST-3.

An increase in traffic volumes along Pacheco Boulevard would correlate to an increase in noise levels at the project site. The Martinez General Plan Update forecasts a traffic noise level increase of 1 dBA Ldn along the adjacent segment of Pacheco Boulevard by the year 2040, with the future Ldn projected to reach 71 dBA at 75 feet from the roadway centerline.2 Common outdoor us areas are proposed along the south and east boundaries of the site. Existing noise levels measured in these areas ranged from 55 to 59 dBA Ldn. By 2040, the unmitigated noise level would be expected to increase by 1 dBA Ldn and would range from 56 to 60 dBA Ldn. The project also proposes the construction of a 6-foot masonry wall along the south boundary of the site that would provide additional noise reduction. Therefore, future exterior noise levels would be less than 60 dBA Ldn and within the “normally acceptable” noise and land use compatibility range identified for residential land uses. 2 City of Martinez Revised Draft General Plan 2035, Noise and Air Quality Element, November 2021. Accessed May 10, 2022 via https://www.cityofmartinez.org/home/showpublisheddocument/2069/637816480405730000. 445 7 Future Interior Noise Environment The City of Martinez requires interior noise levels to be maintained at or below 45 dBA Ldn to be considered acceptable for residential development. In residential units of standard construction, interior noise levels are approximately 15 decibels lower than exterior noise levels with the windows partially open. Standard construction with forced air ventilation (allowing the occupant to control noise by maintaining the windows shut) provides approximately 20 to 25 dBA of noise reduction in interior spaces. This method of reducing interior noise levels is normally used in noise environments ranging from 60 to 65 dBA Ldn. Where noise levels exceed 65 dBA Ldn, forced-air mechanical ventilation systems and sound-rated construction methods are normally required. Unshielded second- and third-story façades of the apartment building would be exposed to future noise levels up to 69 dBA Ldn. Calculations were made to estimate the transmission loss provided by the proposed building elements to determine the expected interior noise levels resulting from traffic. Interior noise levels were calculated based on a review of the project’s site plan, exterior building elevations, and floor plans. The relative areas of walls, windows, and doors were input into an acoustical model to calculate interior noise levels within the proposed residential building. Based on typical California construction techniques, the analysis assumed that the proposed residences would have a three-coat stucco exterior siding (7/8-in.) over Tyvek, 1/2-in. CDX plywood, wood stud framing, R22 cavity insulation, and a single layer of 5/8-in.gypsum board at the interior face. The sound isolation rating of this exterior wall assembly would be STC 46. Windows and doors were then tested to determine the necessary sound transmission class ratings of these building elements in order to reduce interior noise levels due to traffic to acceptable levels. The calculations showed that standard thermal-pane residential windows/doors with a minimum rating of STC 26 would be required. All residential units should be mechanically ventilated by some form of forced-air mechanical ventilation, satisfactory to the local building official, to allow occupants the option of closing the windows and doors to control noise. 446 8 FIGURE 1 Aerial Image Showing Noise Measurement Locations Source: Google Earth 2022. 447 9 448 10 449 11 450 12 451 13 452 14 453 AERIAL MAP 0 PACHECO BLVD, MARTINEZ, CA ASSESSOR'S PARCEL MAP SUBJECT PROPERTY WINDHOVER TERRACE APARTMENTS APN: 380-220-066 G:\SHARED DRIVES\WCLD\AUTOCAD AND REVIT\CAD WCLD\WINDHOVER\00_WINDHOVER G1_GENERAL_TITLE SHT_11MAR2022.DWG 3/15/2022 3:03 PMCUSTOM APARTMENTSDRAWN BY: of Sheet Sheet JOB: SCALE: DATE:(925) 246-2870CONCORD, CA 94520145 JOHN GLENN DRIVEWEST COAST LAND ANDDEVELOPMENT, INC.WWW.WCLANDS.COM10-19-2021 G1GENERAL TITLE SHEET NONE ABBREVIATIONS FND AND& AT@ FLOORFLR CEILING TO BE VERIFIEDTBV VERTICALVERT WITHOUTW/O UNIFORM BUILDING CODE UNLESS OTHERWISE NOTED WITH WITHIN UBC UON W/ W/I ADDITIONALADDL CLG UNLESS OTHERWISE SHOWNUOS VERIFY IN FIELDVIF ABOVEABV ROOFRF DRAWING(S)DWG NEW NOT TO SCALE (N) NTS CNR CORNER CONT CONTINUOUS CONC CONCRETE DELETEDEL DOUBLEDBL DETAILDET / DTL EACHEA ELEVATIONELEV FINISH/FINISHINGFIN EXISTING(E) FOUNDATION HEIGHTHT HORIZONTALHORIZ INTERNATIONAL CONFERENCE OF BUILDING OFFICIALSICBO INTERIOR, INTERSECTIONINT MINIMUMMIN MAXIMUMMAX SQUARESQ STANDARDSTD EXTERIOREXT EXTENDETD CBC CALIFORNIA BUILDING CODE 14.

Staff Recommendation 522 QUESTIONS? 523 524 525 526 FINDINGS AND CONDITIONS OF APPROVAL FOR COUNTY FILE #CDDP23-03020; HARPREET HANSRA (APPLICANT & OWNER) I. FINDINGS A. Small Lot Design Review Findings In approving a Development Plan in the R-10 Single-Family Residential District (R-10), findings are required that the proposed project is consistent with the intent and purpose of the R-10 district and is compatible with other uses in the vicinity, both inside and outside the district. For applications that are Development Plans for a Small Lot Design Review, the Development Plan compatibility findings are the Small Lot Design Review findings for compatibility with the surrounding neighborhood, in terms of its location, size, height, and design. 1. Small Lot Design Review Findings: The proposed project is compatible with the surrounding neighborhood in terms of its (a) location, (b) size, (c) height, and (d) design. a. Location: The project involves a 1,400-square-foot second story addition and a rear porch extension. The proposed project meets all-setback requirements and the height requirements of the R-10 Single-Family Residential District. The location of the addition is compatible as it is a vertical addition and fits within the footprint of the existing house. The location of the rear porch extension is compatible as it is extending an existing covered porch located in the rear and will be fully located underneath the second story addition. The proposed addition and rear porch extension do not exacerbate existing setback distances and is located in an area that will not be heavily intrusive to surrounding neighbors. The addition is designed to be step back from the front and side first floor which allows for the mass to be broken up at the second level. Additionally, the addition is not over the garage portion of the existing residence which allows for views to continue to be maintained behind the house. As a result, the project would be compatible with the surrounding neighborhood in terms of setbacks and design. b. Size: Home sizes in this single-family residential neighborhood and immediate vicinity range between 2,500 square feet to over 5,000 square feet in size on lots that range between 7,000 to 15,000 square feet. The residence will have a total of 3,600 square feet of living space with the second story addition and an additional 85 square feet for the extension of the covered porch. This is well 527 BOS – March 26, 2024 CDDP23-03020 Page 2 of 7 between the range of size for surrounding residences who also have rear covered porches. The location of the addition will also be stepped back towards the rear of the house which will decrease the overall size and bulk. The extension of the rear porch will also be in the rear which will not increase the overall size and bulk of that area. Therefore, the addition would be compatible with the surrounding neighborhood. c. Height: The project meets the R-10 zoning height requirements. The project meets the maximum story requirement by proposing two stories (where two and one-half is the maximum) and the maximum height requirement by proposing a total height of 23’-8 ½” (where 35 feet is the maximum). Comparably, surrounding homes have heights starting from 15 feet to almost 33 feet tall. Staff has surveyed the surrounding streets including Freeman Road, Stanley Court, Melody Drive, Hilton Road, Hilton Court, Juanita Drive, Ponderosa Lane and Manzanita Court and identified numerous residences with second stories that reside on neighboring streets. Moreover, there are a few houses with design features that include a high roof pitch with large dormer windows at a higher roof height which give the impression of it being a two- story home. d. Design: The applicant has designed the project to match the overall characteristic of the neighborhood. The majority of the houses within this area are either simple craftsman/craftsman-adjacent or ranch style homes that incorporate various horizonal, vertical siding, shed and gable roofs with tapered and straight porch posts, wide trims and groupings of one, two or three window bays. Many homes in this area also incorporate composite shingle roofing while utilizing an earth rich/neutral color palette for the walls. Staff has reviewed the neighborhood and has identified that there is no one uniform or consistent design theme in the neighborhood, but rather houses share a few common design features with each other. The proposed project will match the roofing material of neighboring houses by using composite shingle roofing, will match the color scheme by using a white and blue paint with brown brick to match the earth rich/neutral color palette of this neighborhood and will incorporate the craftsman style such as utilizing horizontal lap sliding which is a common siding material in this area and will match the window bay groupings of two and three which is a common window grouping style in this area. The project also matches the vertical siding at the gable ends of the roof which can be found on several homes in the surrounding neighborhood on Hilton Drive, Stanley Court, Melody Drive and Freeman Road. Lastly, the project is designed to be minimally intrusive as it will also incorporate existing design features of 528 BOS – March 26, 2024 CDDP23-03020 Page 3 of 7 the single-story such as continuing the shake style siding on one portion of the walls, will incorporate the same gable roof pitch and is installing a short eave where the rear porch extension is to soften the bottom edge of the master suite so the view of the rear appears to be less blocky, thereby making it one cohesive design. CONDITIONS OF APPROVAL FOR COUNTY FILE #CDDP23-03020 Project Approval Development Plan for a Small Lot Design Review 1. This DEVELOPMENT PLAN for a SMALL LOT DESIGN REVIEW is APPROVED for the construction of a second story, approximately 1,400-square-foot residential addition and an approximately 85-square-foot rear porch extension to the existing single-family residence located at 3455 Freeman Road, Lafayette. 2. The Development Plan approval described above is granted as generally shown on: • The application and project plans received by the Department of Conservation and Development, Community Development Division (CDD) on July 3, 2023: • Supplemental application materials received on August 1, 2023. 3. Any change from the approved plans shall require review and approval by the CDD and may require the filing of an application to modify this Development Plan. 4. The applicant shall obtain a building permit for the work approved under this Development Plan permit. Payment of Fees 5.

III.BACKGROUND An application for the approval of a Small Lot Design Review application for the construction of an approximately 1,400-square-foot, second story addition was first submitted under County File CDSL23-00048 on May 31, 2023. A notice of opportunity to request a public hearing was sent on June 8, 2023, with a deadline of 5:00 pm on Monday, June 19, 2023, for any request for a public hearing. Three hearing requests were received during the required 10-day public hearing comment period for the Small Lot Design Review application. A required development plan application, in response to the three public hearing requests, was submitted on July 3, 2023 (County File #CDDP23-03020). The Development Plan #CDDP23-03020, was initially heard by the County Zoning Administrator on October 2, 2023, during which the County Zoning Administrator accepted testimony from the applicant and members of the public. After receiving testimony and considering the project analysis provided by County staff, the County Zoning Administrator approved the Development Plan. Staff received one letter appealing the Zoning Administrator’s October 2, 2023, decision from Jason & Iva Schwarz on October 12, 2023, which included a list of neighbors who signed the appeal letter. Staff’s analysis and response to the appeal letter is discussed in Section VII (Appeal of Zoning Administrator’s October 2, 2023, decision) of this Staff report. IV.SITE/AREA DESCRIPTION 558 County Planning Commission – January 24, 2024 County File #CDDP23-03020 Page 3 of 9 Site Description: The subject property is located at 3455 Freeman Road, in the unincorporated Lafayette area of Contra Costa County. The property is fronted by two public roads, Freeman Road to the North which accesses the existing driveway, and Olympic Boulevard to the south. The subject parcel is 8,118 square feet and contains an existing 2,200 square foot single-story residence. The site contains some vegetation and trees located in the front yard and the rear yard. The property does not have much topography and is very flat. Surrounding Land Uses: The subject parcel is approximately 300 feet east of the City of Lafayette jurisdiction border, is approximately 4500 feet southwest of the City of Walnut Creek jurisdiction border and is approximately 5200 feet southwest of Interstate 680. The parcel is located in an area of unincorporated Lafayette that is pre-dominantly single-family residences. All adjacent parcels in a 300-foot radius are zoned R-10. Further north are R-10 zoned parcels and further south is a patch of R-20 zoned parcels. Parcels along Freeman Road in the immediate vicinity typically range from 7,000 – 15,000 square feet in area. V. PROJECT DESCRIPTION The applicant requests approval of a Small Lot Design Review Development Plan to construct a second story, approximately 1,400-square-foot residential addition on to an existing single-family residence and will add approximately 85 square feet to extend an existing rear porch. The porch extension is due to the second story addition being placed directly above the porch and an existing walkway, enclosing it from the top. The second story addition will consist of the following: •Four Bedrooms •One Loft •Two Bathrooms •One Utility Closet •One Laundry Room The overall addition will bring the residence from its original 2,200 square feet of residential space to 3,600 square feet with an additional 85 square feet of covered rear porch. Other work that is not included in the Small Lot Design Review Development Plan application is an interior remodel to the exiting kitchen and a sliding glass door. VI.APPEAL OF ZONING ADMINISTRATOR’S OCTOBER 2, 2023, DECISION During the appeal period following approval by the Zoning Administrator, one appeal was received from Jason and Iva Schwarz. In the correspondence received on October 12, 2023, Jason and Iva Schwarz filed an appeal on behalf of the signed neighbors included on the 559 County Planning Commission – January 24, 2024 County File #CDDP23-03020 Page 4 of 9 letter, appealing the Zoning Administrator’s decision. The concerns raised in the letter of appeal, and staff’s responses, are summarized as follows: 1.Summary of Appeal Point #1: The appellant stated that the noticing for the public hearing was deficient because many neighbors did not receive the public hearing notice or received the notice too late. Staff Response: County Code Section 26-2.2004- Notice Requirements states that the “Planning Department shall schedule a hearing before the appropriate division and mail notice thereof pursuant to Government Code Section 65905.” California Code, Government Code §65091 states “that Notice of the hearing shall be mailed or delivered at least 10 days prior to the hearing to all owners of real property as shown on the latest equalized assessment roll within 300 feet of the real property that is the subject of the hearing.” For all projects that require a public hearing notification, County Staff prepares and reviews a 300-foot notification list which encompasses all addresses and property owners within the required noticing area. Staff reviewed the 300-foot notification list and identified all residents within the 300-foot noticing area who claim did not receive the notice in the appeal letter. Additionally, when the County mails out the public hearing notices, a signed affidavit is filled out as proof that the notice was mailed to the property owners identified in the 300-foot notification list which includes names and addresses of each neighbor and an actual map of the 300-foot list. Staff has a signed affidavit dated September 19, 2023, which declares that the public hearing notice was mailed to all addresses on the 300-foot list, 12 calendar days before the scheduled public hearing on October 2, 2023. A scanned copy of the signed affidavit is included as attachment #3 –Public Notice Affidavit. Therefore, County Staff followed the correct notification process as dictated by Government Code §65091 and County Code Section 26- 2.2004. 2.Summary of Appeal Point #2: The appellant expresses concern that the guidelines for a small lot review were not followed as the project was not compared to other substandard lots within the neighborhood for compatibility and that the project size is incompatible. Staff Response: County Code Section 82-10.002(c) – Small Lot Occupancy states that a building permit can be issued for a small lot if the Zoning Administrator determines that the proposed project us compatible with the surrounding neighborhood in terms of its location, size, height and design. The County Code specifically states that compatibility with the surrounding neighborhood must be made and does not require the County to only compare the project to other substandard lots. Rather, the intent of the code is to allow the Zoning Administrator to determine the 560 County Planning Commission – January 24, 2024 County File #CDDP23-03020 Page 5 of 9 compatibility of the project to the surrounding neighborhood which includes lots of various sizes and shapes. Moreover, the code does not distinguish what qualifies as the surrounding neighborhood as the County is not uniform and every neighborhood in the County is different. For the analysis of this project, Staff relied on the boundaries of the Community that the project is located in. The subject parcel is in the Saranap neighborhood. The Saranap area includes parcels and houses on streets that are on the subject street (Freeman Road), or streets that are directly accessed from Freeman Road including Melody Drive, Stanley Court, Freeman Court, Hilton Court, Hilton Road, Juanita Drive and Ponderosa Lane. All houses surveyed for compatibility are approximately within 1,000 feet from the subject parcel and Staff identified multiple two-story houses within this radius. The County cannot exclude parcels that are smaller or larger than the subject parcel from their review because the lot size is not exactly the same. The appellant states that the proposed square footage of the project would be double that of the surrounding neighborhood. The project size has been determined to be compatible with the surrounding neighborhood because this area of the County contains houses with a wide range of sizes. Moreover, development patterns in the Saranap area are showing that houses are growing as more homeowners improve the livability of their property. Therefore, when surveying nearby homes, the project which will have 3,600 is consistent with total square footage as shown in the below table. Address Square Footage 3454 Freeman Road 185-250-020 2,907 SF 3522 Freeman Road 185-250-030 4,433 SF 3514 Freeman Road 185-250-024 3,087 SF 24 Stanley Court 185-250-017 3,105 SF 3362 Freeman Road 185-220-016 3,668 SF 3351 Freeman Road 185-220-001 3,285 SF 3300 Freeman Road 185-220-008 3,608 SF 3506 Freeman Road 185-250-023 3,234 SF 561 County Planning Commission – January 24, 2024 County File #CDDP23-03020 Page 6 of 9 1015 El Curtola Blvd 185-270-025 4,336 SF 3565 Melody Drive 185-250-035 3,154 SF 3541 Melody Drive 185-250-037 3,398 SF 3547 Melody Drive 185-250-038 3,213 SF *Square footage is from Assessor’s Information and Zillow As shown in the table above, the proposed residence is well within the range of square footage for houses within the Saranap neighborhood. Therefore, because the Small Lot Design Review Findings can be made (See attachment 1 – Findings and Conditions of Approval) which determine that the project is compatible with the surrounding neighborhood with respect to the location, size, height and design. 3.Summary of Appeal Point #3: The appellant stated that County Staff relied exclusively on homes outside of the immediate neighborhood when reviewing the project for small lot design review compatibility and there are no two-story homes within 1,000 feet. Staff Response: As stated in Staff’s Response to appeal point #2, the County Ordinance does not specify a minimum or maximum distance when determining the boundaries of a neighborhood for references of compatibility. For the analysis of this project, Staff relied on the boundaries of the established Community that the project is located in. The subject parcel is within the Saranap neighborhood. Examining surrounding main roads and routes into the subject neighborhood, the significant entrances into the area include Bridgefield road on the south and Kinney Drive on the north. Freeman Road is bound to the south by Olympic Boulevard which acts as a natural barrier for the extent of the “neighborhood.” As delineated on County map (see attachment 4 – Saranap Compatibility Map), the Saranap neighborhood encompasses all of Freeman Road, Hilton Court and Road, Melody Drive, Stanley Court, Juanita Drive, Ponderosa Lane and many more streets. The appellant is stating that homes on Melody Drive should not have been used for compatibility when these homes are located less than 500 feet away are directly accessed from Freeman Road. When reviewing homes on these streets, Staff found numerous two-story homes or homes with two-story elements within 1,000 feet. The below table represents the location of a two-story home and the distance in a straight line from the subject parcel. 562 County Planning Commission – January 24, 2024 County File #CDDP23-03020 Page 7 of 9 Address of two-story house or house with two-story elements Location from Project 25 Hilton Court 185-250-029 Approx. 617 Feet North of Project 741 Hilton Road 185-260-004 Approx. 871 Feet North of Project 3514 Freeman Road 185-250-024 Approx. 468 Feet North of Project 3522 Freeman Road 185-250-030 Approx. 621 Feet North of Project 3448 Freeman Road 185-250-014 Approx. 57 Feet North of Project 835 Juanita Drive 185-270-005 Approx. 957 Feet North of Project 860 Juanita Drive 185-250-033 Approx. 715 Feet North of Project 865 Juanita Drive 185-250-033 Approx. 965 Feet North of Project 3565 Melody Drive 185-250-035 Approx. 750 Feet East of Project 3541 Melody Drive 185-250-039 Approx. 570 Feet East of Project 3559 Melody Drive 185-250-036 Approx. 750 Feet East of Project 3547 Melody Drive 185-250-038 Approx. 530 Feet East of Project 3553 Melody Drive 185-250-037 Approx. 615 Feet East of Project 144 Ponderosa Lane 185-241-019 Approx. 766 Feet North of Project As stated before, the size of a parcel does not disqualify that parcel from being included in a compatibility analysis. County Code 82-10.002(c) requires the Zoning Administrator to determine that the proposed project is compatible with the surrounding neighborhood. In this case, the neighborhood is the Saranap Area which allows Staff to survey all parcels within the boundaries. Therefore, Staff has reviewed all parcels within a reasonable radius of the subject parcel and has determined from the table above that there are multiple two-story homes within 1,000 feet of the subject parcel. 563 County Planning Commission – January 24, 2024 County File #CDDP23-03020 Page 8 of 9 4.Summary of Appeal Point #4: The appellant stated that two story homes in this neighborhood are only on larger parcel lots and that a two-story home on a substandard lot would negatively impact the neighborhood in regard to privacy. Staff Response: In determining compatibility with the surrounding neighborhood, County Staff relies on the R-10 Zoning Ordinance and the development patterns of the neighborhood. The size of a parcel does not disallow a two-story development. The project conforms to the development standards of the R-10 District. The project does not exceed the two and one-half stories or thirty-five feet in height requirement. The project meets and exceeds all setback requirements for the front, secondary frontage and side. Additionally, the project is designed to be less obtrusive by stepping back the addition and locating it towards the rear of the residence, with a height that is within the maximum allowance. Moreover, the applicant has designed the project to match the overall characteristic of the neighborhood including matching the styles and architecture patterns of surrounding houses and incorporating them into the project. The project which is residential in nature is consistent with the development pattern of this area in that smaller lots will build up instead of outwards as the small lot size restricts development due to the setback requirements. Moreover, because the project meets the required setbacks, there is the required space between parcels that is required to maintain privacy. The project has been designed to avoid any such privacy impacts. The bedroom windows for the second story have been designed to be facing away private places in neighboring residences. The windows that on the side of the addition that face the east and west toward the neighboring residences overlook the roofs of the neighboring residences and do not have a view into the rear yard. The rear bedroom on the second floor is designed to be located in the center of the lot to protect privacy with a minimum number of side windows that are setback 22 feet from the closest residence to the east and setback 25 feet from the closest residence from the west. This setback distance enhances privacy for the neighbors. Furthermore, the Small Lot Design Review findings related to the location, size, height and design of the project are supported (see attachment 1 – Findings and Conditions of Approval). Therefore, the project would not have a significant negative impact on the character of the neighborhood because the project meets and exceeds all requirements of the R-10 zoning code and is compatible with other surrounding developments that have two-story elements. 5. Summary of Appeal Point #5: The appellant expressed concerns that the property owner made no effort to contact the neighbors to discuss the project. Staff Response: The County Ordinance does not require an applicant to engage with surrounding neighbors in regard to their project. Furthermore, public hearings 564 County Planning Commission – January 24, 2024 County File #CDDP23-03020 Page 9 of 9 provide a forum for neighbors to bring their questions and concerns for discussion. VII.CONCLUSION The proposed project is consistent with applicable goals and policies of the General Plan, and also with the intent of the SM General Plan Designation and the R-10 Zoning District. The project is consistent with the established area as single-family residences with two-story elements are a common occurrence. The Small Lot Design Review findings are made which determines that the proposed second story addition is compatible with the Saranap community. Therefore, Staff recommends that the County Planning Commission deny the appeal and approve County File #CDDP23-03020, based on the attached findings and subject to the attached conditions of approval.

FINDINGS A. Small Lot Design Review Findings In approving a Development Plan in the R-10 Single-Family Residential District (R-10), findings are required that the proposed project is consistent with the intent and purpose of the R-10 district and is compatible with other uses in the vicinity, both inside and outside the district. For applications that are Development Plans for a Small Lot Design Review, the Development Plan compatibility findings are the Small Lot Design Review findings for compatibility with the surrounding neighborhood, in terms of its location, size, height, and design. 1. Small Lot Design Review Findings: The proposed project is compatible with the surrounding neighborhood in terms of its (a) location, (b) size, (c) height, and (d) design. a. Location: The project involves a 1,400-square-foot second story addition and a rear porch extension. The proposed project meets all-setback requirements and the height requirements of the R-10 Single-Family Residential District. The location of the addition is compatible as it is a vertical addition and fits within the footprint of the existing house. The location of the rear porch extension is compatible as it is extending an existing covered porch located in the rear and will be fully located underneath the second story addition. The proposed addition and rear porch extension do not exacerbate existing setback distances and is located in an area that will not be heavily intrusive to surrounding neighbors. The addition is designed to be step back from the front and side first floor which allows for the mass to be broken up at the second level. Additionally, the addition is not over the garage portion of the existing residence which allows for views to continue to be maintained behind the house. As a result, the project would be compatible with the surrounding neighborhood in terms of setbacks and design. b. Size: Home sizes in this single-family residential neighborhood and immediate vicinity range between 2,500 square feet to over 5,000 square feet in size on lots that range between 7,000 to 15,000 square feet. The residence will have a total of 3,600 square feet of living space with the second story addition and an additional 85 square feet for the extension of the covered porch. This is well 566 County Planning Commission – January 24, 2024 CDDP23-03020 Page 2 of 6 between the range of size for surrounding residences who also have rear covered porches. The location of the addition will also be stepped back towards the rear of the house which will decrease the overall size and bulk. The extension of the rear porch will also be in the rear which will not increase the overall size and bulk of that area. Therefore, the addition would be compatible with the surrounding neighborhood. c. Height: The project meets the R-10 zoning height requirements. The project meets the maximum story requirement by proposing two stories (where two and one-half is the maximum) and the maximum height requirement by proposing a total height of 23’-8 ½” (where 35 feet is the maximum). Comparably, surrounding homes have heights starting from 15 feet to almost 33 feet tall. Staff has surveyed the surrounding streets including Freeman Road, Stanley Court, Melody Drive, Hilton Road, Hilton Court, Juanita Drive, Ponderosa Lane and Manzanita Court and identified numerous residences with second stories that reside on neighboring streets. Moreover, there are a few houses with design features that include a high roof pitch with large dormer windows at a higher roof height which give the impression of it being a two- story home. d. Design: The applicant has designed the project to match the overall characteristic of the neighborhood. The majority of the houses within this area are either simple craftsman/craftsman-adjacent or ranch style homes that incorporate various horizonal, vertical siding, shed and gable roofs with tapered and straight porch posts, wide trims and groupings of one, two or three window bays. Many homes in this area also incorporate composite shingle roofing while utilizing an earth rich/neutral color palette for the walls. Staff has reviewed the neighborhood and has identified that there is no one uniform or consistent design theme in the neighborhood, but rather houses share a few common design features with each other. The proposed project will match the roofing material of neighboring houses by using composite shingle roofing, will match the color scheme by using a white and blue paint with brown brick to match the earth rich/neutral color palette of this neighborhood and will incorporate the craftsman style such as utilizing horizontal lap sliding which is a common siding material in this area and will match the window bay groupings of two and three which is a common window grouping style in this area. The project also matches the vertical siding at the gable ends of the roof which can be found on several homes in the surrounding neighborhood on Hilton Drive, Stanley Court, Melody Drive and Freeman Road. Lastly, the project is designed to be minimally intrusive as it will also incorporate existing design features of 567 County Planning Commission – January 24, 2024 CDDP23-03020 Page 3 of 6 the single-story such as continuing the shake style siding on one portion of the walls, will incorporate the same gable roof pitch and is installing a short eave where the rear porch extension is to soften the bottom edge of the master suite so the view of the rear appears to be less blocky, thereby making it one cohesive design.

STAFF REPORT Agenda Item #_____ Project Title: Small Lot Design Review Development Plan for a 2-story 1,400-square-foot residential addition and rear porch extension County File(s): #CDDP23-03020 Applicant: Harpreet Hansra Owner: Harpreet Hansra Zoning/General Plan: R-10 Single-Family Residential District (R-10) / Single-Family Residential-Medium Density (SM) Site Address/Location: 3455 Freeman Road, Lafayette, CA 94595 APN: 185-211-014 California Environmental Quality Act (CEQA) Status: The proposed project is exempt under CEQA Guidelines Section 15301(e)(2), Existing Facilities – Addition to Existing Structure Project Planner: Everett Louie, Planner II (925) 655-2873 Everett.Louie@dcd.cccounty.us Staff Recommendation: Approve (See section II for full recommendation) I. PROJECT SUMMARY The applicant requests approval of a Small Lot Design Review Development Plan to construct a second story, approximately 1,400-square-foot residential addition and an approximately 85-square-foot extension to an existing rear porch of an existing single-family residence. 583 Zoning Administrator – October 2, 2023 CDDP23-03020 Page 2 of 9 II. RECOMMENDATION A. Staff recommends the Zoning Administrator APPROVE County File #CDDP23- 03020, based on the attached findings and subject to the attached conditions of approval. B. DIRECT staff to file a Notice of Exemption with the County Clerk. III. BACKGROUND The small lot design review request is for the construction of an approximately 1,400- square-foot addition, two-story second story addition. The project was first submitted as County File CDSL23-00048 on May 31, 2023. A notice of opportunity to request a public hearing was sent on June 8, 2023, with a deadline of 5:00 pm on Monday, June 19, 2023, for any request for a public hearing. Three hearing requests were received during the required 10-day public comment period for the Small Lot Design Review. A required development plan application, in response to the three public hearing requests, was submitted on July 3, 2023 (County File #CDDP23- 03020). IV. GENERAL INFORMATION A. General Plan: The subject property is located within a Single-Family Residential - Medium Density (SM) General Plan Land Use Designation. B. Zoning: The subject property is located within a R-10 Single-Family Residential District (R-10). C. California Environmental Quality Act (CEQA) Compliance: The proposed project is exempt under CEQA Guidelines Section 15301. This CEQA section exempts existing facilities, and additions to existing structures of no more than 10,000 square feet in an area that is not environmentally sensitive and where all public services and facilities are available for the maximum development permissible in the General Plan. The proposed project is a 1,400-square-foot addition and an 85-square-foot extension to an existing rear porch of an existing single-family residence. The total square footage added to the proposed project does not exceed 10,000 square feet and the project is not in an area that is environmentally sensitive. The site is currently served by water, sanitary and fire and will continue to be served by public services as the parcel is located within the Urban Limit Line. Therefore, the project is exempt under CEQA Guidelines Section 15301(e)(2). 584 Zoning Administrator – October 2, 2023 CDDP23-03020 Page 3 of 9 D. Lot Creation: The parcel is Lot 7 Block B of the Bridgefield Tract recorded in 1946. The subdivision at that time created the lot. E. Previous Applications: a. CDVR23-01014: A variance and small lot design review application to construct an approximately 1,400-square-foot second story addition with a 10’ aggregate side yard (where 15’ is the minimum). This application was withdrawn as the residential lot was legally created before 1947 which allows for a sliding scale for side yards, and thus, a variance was not required. b. CDSL23-00048: A small lot design review application to construct an approximately 1,400-square-foot second story addition. Three hearing requests were received, and in response, the current development plan application was submitted. V. SITE/AREA DESCRIPTION The subject property is located at 3455 Freeman Road, in the unincorporated Lafayette area of Contra Costa County. The property is fronted by two public roads, Freeman Road to the North which accesses the existing driveway, and Olympic Boulevard to the south. The subject parcel is 8,118 square feet and contains an existing 2,200 square foot single-story residence. The site contains some vegetation and trees located in the front yard and the rear yard. The property does not have much topography and is very flat. The subject parcel is approximately 300 feet east of the City of Lafayette jurisdiction border, is approximately 4500 feet southwest of the City of Walnut Creek jurisdiction border and is approximately 5200 feet southwest of Interstate 680. The parcel is located in an area of unincorporated Lafayette that is pre-dominantly single-family residences. All adjacent parcels in a 300-foot radius are zoned R-10. Further north are R-10 zoned parcels and further south is a patch of R-20 zoned parcels. Parcels along Freeman Road in the immediate vicinity typically range from 7,000 – 15,000 square feet in area. VI. PROJECT DESCRIPTION The applicant requests approval of a Small Lot Design Review Development Plan to construct a second story, approximately 1,400-square-foot residential addition on to 585 Zoning Administrator – October 2, 2023 CDDP23-03020 Page 4 of 9 an existing single-family residence and will add approximately 85 square feet to extend an existing rear porch. The porch extension is due to the second story addition being placed directly above the porch, enclosing it from the top. The second story addition will consist of the following: • Four Bedrooms • One Loft • Two bathrooms • One Utility closet • One Laundry Room The overall addition will bring the residence from its original 2,200 square feet of residential space to 3,600 square feet with an additional 85 square feet of covered rear porch. Other work that is not included in the Small Lot Design Review Development Plan application is an interior remodel to the exiting kitchen and a sliding glass door. VII. AGENCY COMMENTS A. San Ramon Valley Fire Protection District: In a returned comment form dated November 21, 2022, Fire District staff indicated the project is to comply with current Fire code requirements at the time of submittals. No other comments were provided. B. Central Contra Costa Sanitary District: In an email response received on July 14, 2023, Central Contra Costa Sanitary District staff indicated that the project would not be expected to produce an unmanageable added capacity demand on the wastewater system, nor interfere with existing public facilities. C. East Bay Municipal Utility District (EBMUD): In a letter dated March 27, 2023, East Bay Municipal Utility District Staff indicated that the project applicant shall contact EBMUD’s new business office and request a water service estimate. D. Application and Permit Center, Public Works Staff: In a returned agency comment packet dated July 24, 2023, Staff indicated that a flood plain permit is not required. E. Contra Costa Mosquito and Vector Control District: In a returned agency comment packet dated July 18, 2023, Staff indicated that they had no comments on the project. 586 Zoning Administrator – October 2, 2023 CDDP23-03020 Page 5 of 9 No comments were received from the following agencies: Contra Costa County Environmental Health Department, City of Lafayette, and the Contra Costa County, Building Inspection Division. VIII. REQUEST FOR PUBLIC HEARING During the 10-day notice period for County File # CDSL23-03020, staff received three letters requesting a public hearing. The following contains the summarization of comments received and staff’s responses. A. Gayle Schiller: On June 14, 2023, staff received a request for public hearing from the neighbors residing in 20 Stanley Court, Lafayette, CA 94595. Comment: Gayle Schiller has concerns with trucks parking, turning around or using Stanley Court which could create congestion on Stanley Court. Staff Response: Stanley Court is located directly across the street from the project site. Freeman Road is a County maintained road; however, Stanley Court is not a County maintained road and therefore, the County can not impose parking restrictions on a private court. Moreover, the project site has an existing asphalt driveway and asphalt parking area in the front yard where construction vehicles can utilize existing off-street parking on-site. The site has a large enough driveway to allow construction vehicles to turn around on the existing driveway. Staff has included conditions of approval (COA #6-12) that limit the hours of construction to the hours of 8:00 AM to 5:00 PM, Monday through Friday and prohibiting work on State and Federal holidays and limit the use of trucks to weekdays between the hours of 9:00 AM to 4:00 PM and prohibiting work on Federal and State holidays and requiring a good faith effort to park vehicles on the project site. These conditions of approval will help address any construction related issues in regard to having too many vehicles on the site as the use of construction vehicles will be limited to specific hours of the day. B. Nicole Jones & Geoff Foster: On June 14, 2023, staff received a second letter from a neighbor residing at 3454 Freeman Road, Lafayette, CA 94595. Comment: Freeman Road is almost 100% single story homes, and a second story addition is not compatible with design, size and height of our neighborhood. Staff Response: The property is zoned R-10, which allows a maximum height of 587 Zoning Administrator – October 2, 2023 CDDP23-03020 Page 6 of 9 two and one-half stories or thirty-five feet in height. The proposed project is a second story addition that does not exceed thirty-five feet. The project meets the R-10 zoning district height requirement. Additionally, Staff has surveyed the neighboring properties located on the following roads: Freeman Road, Stanley Court, Meledy Court, Hilton Road, Hilton Court, Juanita Drive, Ponderosa Lane and Manzanita Court. These roads contain properties with single-family residences that have two stories. Moreover, there are a few single-story houses along Freeman Road (3448 Freeman Road for example) that incorporate a very high roof pitch with large dormer windows on the roof which give the appearance of a second story. Moreover, the design of the proposed addition utilizes a step back design as the second story addition is placed farther back from the front and is not on top of the garage. This design feature breaks up the massing and bulk of the project and also allows the residents of 3454 Freeman Road to still see over the proposed project as the addition is located on the southeast corner of the residence and will allow for a sight line over the western portion of the house (garage). The extension of the rear porch will be located behind the house which is a consistent location feature for houses along Freeman Road. As stated in the Small Lot Design Review Findings of this Staff report, the project is compatible with the location, size, height and design. The location of the addition is compatible as it is a vertical addition and fits within the footprint of the existing house. The project will not change the existing setbacks as the project will be building up. The bulk of the addition will be in the middle of the residence with part of the addition towards the east. The porch extension at the rear of the house is located in a location that is consistent with surrounding properties. Numerous properties along Freeman Road have porches behind the house. The size of the residence with the proposed addition will be 3,600 square feet while the porch extension will add 85 square feet. Staff has surveyed the surrounding area, and there are houses ranging in size from 2,500 to 5,000 square feet. Therefore, the proposed project is compatible in respect to size. As mentioned above, the project meets the R-10 zoning height requirements and is consistent with other two-story residences in this area of the County. The total height of the project will be approximately 23’-8 ½”. Comparably, surrounding homes have heights from 15 feet to almost 33 feet tall. The proposed project is well within the range of heights for this area of the County. The applicant has designed the project to match the overall characteristic of the neighborhood. Many of the houses within this area are either simple craftsman/craftsman-adjacent or ranch style homes that incorporate various horizonal, vertical siding, shed and gable roofs with tapered and straight porch posts, wide trims and groupings of one, two or three window bays. Many homes in this area also incorporate composite 588 Zoning Administrator – October 2, 2023 CDDP23-03020 Page 7 of 9 shingle roofing while utilizing a neutral color palette for the walls. The proposed project will match the roofing material of neighboring houses by using composite shingle roofing, will match the color scheme by using a white and blue paint with brown brick which is a style in this area and will incorporate the craftsman style such as utilizing horizontal lap sliding which is a common siding material in this area and will match the window bay groupings of two and three which is a common window grouping style in this area. To make the porch extension more cohesive, the applicant will place a small narrow extension of a short eave on the bottom plane of the master suite that extends past the footprint of the house to soften the bottom edge of the master suite so it’s not blocky. Lastly, the project is designed to be minimally intrusive as it will also incorporate existing design features of the single-story such as continuing the shake style siding on one portion of the walls and will incorporate the same gable roof pitch, thereby making it one cohesive design. C. Jason Schwarz: On June 14, 2023, staff received a third letter from a neighbor residing at 3471 Freeman Road, Lafayette, CA 94595 Comment: Jason Schwarz submitted a letter requesting a public hearing. Staff Response: In the request for a public hearing, Jason Schwarz did not specify any specific concerns or issues with the proposed project. IX. STAFF ANALYSIS A. Consistency with General Plan: The residence at 3455 Freeman Road is located within a Single-Family Residential – Medium Density (SM) General Plan Land Use designation. The SM designation is intended to promote the orderly development of residential neighborhoods at the density level of 3.0-4.9 units per net acre. The homes along Freeman Road, have been developed so that the residential development is consistent with the SM designation. Primary land uses permitted in this designation include single-family homes and accessory buildings and structures. The proposed project is to add a second story addition and extend and existing porch of an existing single-family residence. This is a consistent use with the General Plan Land Use designation. The proposed addition would not change the use of the site or the residential density, and therefore, would be consistent with the SM designation. Further, the single-family residence with the proposed addition would remain consistent with the residential character of the neighborhood, and thereby would not disrupt the orderly development of this neighborhood. 589 Zoning Administrator – October 2, 2023 CDDP23-03020 Page 8 of 9 B. Consistency with Zoning: The subject property is located within a R-10 Single- Family Residential District (R-10). The intent of the R-10 Zoning District is to provide orderly development of single-family residential uses, accessory structures and uses normally auxiliary to them. The proposed project involves a 1,400-square-foot, second story addition and an approximately 85-square-foot extension to the existing rear porch. The proposed addition and rear porch extension would conform to the development standards of the R-10 District as shown below due to the addition being placed directly on top of the existing single-family residence. The proposed project does not exacerbate the existing setback dimensions of the single-family residence as indicated in the table below. Project Development Standards Of The R-10 Single-Family Residential District Development Standard Required Proposed Lot-Area 10,000 sq ft 8,118 sq ft* Lot-Width 80’ 65.9’ Building Height Two and one-half stories or thirty-five feet in height 23’-8 1/2” and two stories Yard-Side Yard-Setback Yard – Sec. Frontage (Olympic) Yard-Rear 5’ min, 15’ agg (sliding scale)** 20’ 15’ 15’ 5’ min, 26’-6” agg 41’-8 ½” 27’-9” No rear yard, double frontage * Small Lot Design Review Required ** Lot was created in 1946, subject to sliding scale per 82-14.004. As stated in the above table, the proposed addition would conform to the development standards of the R-10 District, including maximum height, setback and yard requirements. The subject property is consistent with the lot requirements for property in the R-10 Single-Family Residential District except for the 65.9-foot lot width requirements (the lot is required to have 80 feet in average width), and therefore, the Small Lot Design Review was required. C. Compatibility with Surrounding Neighborhood: The proposed project must be found to be compatible with the surrounding neighborhood in terms of its location, size, height, and design in order to approve the Small Lot Design Review per County Code Section 82-10.002(c). Staff have made the required Small Lot Design Review findings. These findings are included in attachment 1 – Findings and Conditions of Approval, to this Staff Report. D. Appropriateness of the Use: The proposed project is a second story addition to an existing single-family residence with an extension of an existing porch attached to the house. As stated in the Staff Report, the project meets the R-10 590 Zoning Administrator – October 2, 2023 CDDP23-03020 Page 9 of 9 Zoning District guidelines and is consistent with the General Plan Single-Family Residential-Medium Density (SM) Land Use Designation and is consistent with the Small Lot Occupancy findings. The site and area surrounding this parcel are zoned for single-family uses and additions to single-family residences are common development projects in this area, therefore, the project is an appropriate use of the site. X. CONCLUSION The applicant proposes an approximately 1,400-square-foot second story addition and an approximately 85-square-foot rear covered porch extension. As mentioned in the Staff Report, the proposed project is consistent with the Single-Family Residential – Medium Density (SM) General Plan Designation and complies with the intent and purpose of the R-10 Single-Family Residential Zoning District. With respect to Small Lot Design Review, the proposed project is compatible with the surrounding neighborhood in terms of its location, size, height and design. Staff recommends approval of Development Plan #CDDP23-03020, subject to the attached findings and conditions of approval. Attachments: 1. Findings and Conditions of Approval 2. Maps – Parcel Map, General Plan, Zoning, and Aerial Photograph 3. Public Comments 4. Agency Comments 5. Project Plans 591 FINDINGS AND CONDITIONS OF APPROVAL FOR COUNTY FILE #CDDP23-03020; HARPREET HANSRA (APPLICANT & OWNER) I. FINDINGS A. Small Lot Design Review Findings In approving a Development Plan in the R-10 Single-Family Residential District (R-10), findings are required that the proposed project is consistent with the intent and purpose of the R-10 district and is compatible with other uses in the vicinity, both inside and outside the district. For applications that are Development Plans for a Small Lot Design Review, the Development Plan compatibility findings are the Small Lot Design Review findings for compatibility with the surrounding neighborhood, in terms of its location, size, height, and design. 1. Small Lot Design Review Findings: The proposed project is compatible with the surrounding neighborhood in terms of its (a) location, (b) size, (c) height, and (d) design. a. Location: The project involves a 1,400-square-foot second story addition and a rear porch extension. The proposed project meets all-setback requirements and the height requirements of the R-10 Single-Family Residential District. The location of the addition is compatible as it is a vertical addition and fits within the footprint of the existing house. The location of the rear porch extension is compatible as it is extending an existing covered porch located in the rear and will be fully located underneath the second story addition. The proposed addition and rear porch extension do not exacerbate existing setback distances and is located in an area that will not be heavily intrusive to surrounding neighbors. The addition is designed to be step back from the front and side first floor which allows for the mass to be broken up at the second level. Additionally, the addition is not over the garage portion of the existing residence which allows for views to continue to be maintained behind the house. As a result, the project would be compatible with the surrounding neighborhood in terms of setbacks and design. b. Size: Home sizes in this single-family residential neighborhood and immediate vicinity range between 2,500 square feet to over 5,000 square feet in size on lots that range between 7,000 to 15,000 square feet. The residence will have a total of 3,600 square feet of living space with the second story addition and an additional 85 square feet for the extension of the covered porch. This is well 592 Zoning Administrator – October 2, 2023 CDDP23-03020 Page 2 of 7 between the range of size for surrounding residences who also have rear covered porches. The location of the addition will also be stepped back towards the rear of the house which will decrease the overall size and bulk. The extension of the rear porch will also be in the rear which will not increase the overall size and bulk of that area. Therefore, the addition would be compatible with the surrounding neighborhood. c. Height: The project meets the R-10 zoning height requirements. The project meets the maximum story requirement by proposing two stories (where two and one-half is the maximum) and the maximum height requirement by proposing a total height of 23’-8 ½” (where 35 feet is the maximum). Comparably, surrounding homes have heights starting from 15 feet to almost 33 feet tall. Staff has surveyed the surrounding streets including Freeman Road, Stanley Court, Melody Drive, Hilton Road, Hilton Court, Juanita Drive, Ponderosa Lane and Manzanita Court and identified numerous residences with second stories that reside on neighboring streets. Moreover, there are a few houses with design features that include a high roof pitch with large dormer windows at a higher roof height which give the impression of it being a two- story home. d. Design: The applicant has designed the project to match the overall characteristic of the neighborhood. The majority of the houses within this area are either simple craftsman/craftsman-adjacent or ranch style homes that incorporate various horizonal, vertical siding, shed and gable roofs with tapered and straight porch posts, wide trims and groupings of one, two or three window bays. Many homes in this area also incorporate composite shingle roofing while utilizing an earth rich/neutral color palette for the walls. Staff has reviewed the neighborhood and has identified that there is no one uniform or consistent design theme in the neighborhood, but rather houses share a few common design features with each other. The proposed project will match the roofing material of neighboring houses by using composite shingle roofing, will match the color scheme by using a white and blue paint with brown brick to match the earth rich/neutral color palette of this neighborhood and will incorporate the craftsman style such as utilizing horizontal lap sliding which is a common siding material in this area and will match the window bay groupings of two and three which is a common window grouping style in this area. The project also matches the vertical siding at the gable ends of the roof which can be found on several homes in the surrounding neighborhood on Hilton Drive, Stanley Court, Melody Drive and Freeman Road. Lastly, the project is designed to be minimally intrusive as it will also incorporate existing design features of 593 Zoning Administrator – October 2, 2023 CDDP23-03020 Page 3 of 7 the single-story such as continuing the shake style siding on one portion of the walls, will incorporate the same gable roof pitch and is installing a short eave where the rear porch extension is to soften the bottom edge of the master suite so the view of the rear appears to be less blocky, thereby making it one cohesive design.

The proposed addition would not be expected to produce an unmanageable added capacity demand on the wastewater system, nor interfere with existing public facilities. The applicant should promptly submit full-size building plans for Central San to review and pay all appropriate fees, including for capping and abandoning or reusing the existing sewer lateral due to roof removal. For more information, the applicant should contact the Central San Permit Section at (925) 229- 7371. Thanks!

Engineering and installation of water mains and meters requires substantial lead time, which should be provided for in the project sponsor's development schedule. No water meters are allowed to be located in driveways. The project sponsor should be aware that Section 31 of EBMUD's Water Service Regulations requires that water service shall not be furnished for new or expanded service unless all the applicable water-efficiency measures described in the regulation are installed at the project sponsor's expense. Due to EBMUD's limited water supply, all customers should plan for shortages in time of drought. EBMUD owns and operates a 20-inch water distribution pipeline in an EBMUD right of way (R/W 1981) adjacent to the southern boundary of this property on Olympic Boulevard. This pipeline provides water service to the existing residential property. The integrity of this pipeline needs to be maintained at all times. Any proposed construction activity within the right of way would need to be coordinated with EBMUD and may require relocation of the pipeline and/or right of way, at the project sponsor's expense. No buildings or structures shall be constructed in EBMUD's right of way unless specific approval is given by EBMUD. LJ CC: M.

County Staff has a signed affidavit dated September 19, 2023, which declares that the County mailed the notices 12 calendar days before. ■County Code requires compatibility to be reviewed with respect to the entire surrounding neighborhood. The County does not omit certain lots due to lot size. The Saranap Community contains numerous homes within the project range. Public Hearing Notice Was Deficient Project should only be compared to other substandard lots andt he project size is incompatible 14 633 Appeal Points ■The County surveyed the Saranap neighborhood and identified many houses within 1,000 feet that are two- stories or have two-story elements. ■The project meets the R-10 zoning code development standards and the design of project reduces privacy infringement. The Small Lot Design Review findings support the project compatibility. ■This is not a requirement in the County Ordinance or Development Plan application. No two-story homes in the “neighborhood” Two -story homes on substandard lots negatively impact the neighborhood privacy. The applicant made no effort to discuss the project with neighbors. 15 634 Photos of Surrounding Compatible Homes 16 25 Hilton Court (617 FT North) 3522 Freeman Road 621 FT North) 3448 Freeman Road 57 FT North) 835 Juanita Drive (957 FT North) 3559 Melody Drive (750 FT East) 144 Ponderosa Lane (766 FT north) 635 Staff Conclusion ■The project is consistent with the applicable policies/standards of: –County General Plan –Zoning Consistency –Small Lot Design Review Findings ■The project is a residential addition and promotes residential development growth that is consistent with the Saranap neighborhood. 17 636 Staff Recommendation Staff recommends that the County Planning Commission: ■DENY the appeal by Jason and Iva Schwarz,et al ■APPROVE the project based on the findings and conditions of approval 18 637 QUESTIONS? 19 638 2727 SF 2914 SF 3087 SF 3234 SF 3608 SF 2649 SF 2036 SF 4354 SF 2733 SF 3015 SF 2347 SF 1794 SF 2746 SF 2697 SF 3227 SF 2884 SF 2282 SF2850 SF2674 SF 2079 SF 2358 SF 3427 SF 3668 SF 1453 SF 2693 SF 2224 SF 1680 SF 2056 SF 1651 SF 3573 SF1506 SF 2120 SF 3398 SF 2645 SF 1516 SF 2504 SF3325 SF1516 SF 3285 SF 3087 SF 2210 SF 1742 SF 2362 SF 1936 SF 2925 SF 2049 SF 2313 SF 1673 SF 2776 SF 2055 SF 1084 SF 2346 SF 1457 SF 2507 SF 2994 SF 2055 SF 1530 SF 1414 SF 2044 SF 2907 SF 2531 SF 2446 SF 1876 SF 1543 SF 2574 SF 1856 SF 1456 SF 2610 SF 4433 SF 2037 SF 1586 SF 1404 SF 1450 SF 3213 SF 1664 SF 2148 SF 2040 SF 1685 SF 1118 SF 1158 SF 2187 SF 1950 SF 2064 SF 1961 SF 1472 SF 1233 SF 1753 SF 3213 SF 1927 SF2856 SF 1921 SF 2210 SF 1641 SF 1713 SF 2082 SF 2688 SF 1889 SF 2827 SF 2882 SF 1652 SF 2657 SF1313 SF 2337 SF1664 SF 1619 SF 1967 SF 2984 SF 1855 SF2200 SF 1925 SF1530 SF 2209 SF 1524 SF 954 SF 1314 SF 1881 SF 2228 SF 1272 SF 1364 SF 1689 SF 1271 SF 1971 SF 1204 SF 1225 SF 2044 SF2106 SF 2034 SF 1815 SF 1514 SF 2082 SF 1855 SF 1447 SF 1529 SF 1780 SF 2843 SF 1225 SF 2028 SF 1225 SF 2341 SF 1657 SF 2039 SF 1333 SF 1345 SF 1263 SF 1718 SF1830 SF 1648 SF 927 SF 1314 SF 1330 SF 927 SF 2423 SF1921 SF1610 SF 1858 SF 1615 SF 2223 SF 2844 SF Lafayette Olympic B l v d Olympic B l v d Freeman Rd Juanita Dr Olympic B l v d Boulevard W ay W Newel l A v e WindtreeCt KinneyDrKing DrHilton Rd Newel l Ct Pon d e rosaLnSanfordLnFreeman Ct Hilton Ct u rt o l a Bl vdMelody DrC a r r o l P l Acac iaRdStanley Ctev a r d C t Evergreen CtM a n z a n i t a C t ElDoradoRdMap Created 10/31/2023 by Contra Costa County Department of Conservation and Development, GIS Group 30 Muir Road, Martinez, CA 94553 37:59:41.791N 122:07:03.756WI019038095 Feet This map was created by the Contra Costa County Department of Conservation and Development with data from the Contra Costa County GIS Program.

Diablo Resource Recovery Dear Ms. Dingman: This report provides results of Crowe LLP’s (Crowe) analysis of a rate application (Application) submitted by Garaventa Enterprises (dba Mt. Diablo Resource Recovery – Contra Costa County (“MDRR”)) to Contra Costa County (County) to cover new costs required to comply with Senate Bill 1383 (SB 1383). Garaventa provides refuse, organics, and recycling collection services to unincorporated Contra Costa County. This letter report is organized into eight (8) sections as follows: A. Purpose of Analysis B. Summary Results of Analysis C. Background of Analysis D. Goals and Objectives of Analysis E. Scope of Analysis F. History of Collection Rates G. SB 1383 Rate Application H. Results of Analysis. There are four (4) attachments to this report, as follows: A. SB 1383 Rate Application B. Initial SB 1383 Rate Application (2022) C. Adjusted SB 1383 Rate Model D. Summary Comparison of Other Jurisdictions’ SB 1383 Rate Changes. A. Purpose of Analysis The purpose of this analysis of the SB 1383 rate request submitted by MDRR (Analysis) is to assist the County with establishing rates for refuse and recycling collection to cover new costs required to comply with SB 1383 requirements. Effective January 1, 2022, SB 1383 requires all businesses and residents to separate organics and recyclable materials from trash and either subscribe to the required collection services or self-haul organics to an appropriate facility for diversion. Under SB 1383, organic waste haulers will need to monitor contamination of organic waste containers at the time of collection, and report contamination data to jurisdictions. This Analysis was conducted in accordance with the County’s Rate Setting Process and Methodology Manual Solid Waste Collection Charges (Manual), dated July 15, 2011. The information in this Analysis is based on estimates, assumptions and other data developed from information provided by MDRR, 728 Ms. Deidra Dingman Page 2 March 11, 2024 knowledge of and participation in other studies, data supplied by the County, and other sources deemed to be reliable. B. Summary In its Application, MDRR requested a rate increase of 22.05 percent. Based on the analysis of the Application, and applying the methodology contained in the Manual, we calculated a combined SB 1383 rate increase of 15.02 percent for 2024. Table 1 below shows the rate increase for typical residential customer service levels. For residential customers, this rate increase corresponds to an increase of between $5.14 and $8.86 per customer, per month, depending on the residential service level. Table 2 shows the calculated rate increase for typical commercial customers, depending on the commercial service level. Table 1 Mt.

Background of Analysis On October 12, 2023, MDRR submitted a rate request to the County to cover new costs associated with SB 1383 compliance related activities. MDRR’s 2024 projected SB 1383 compliance costs primarily include: • Capital costs for SB 1383 requirements – container labels, customer outreach, and regulatory compliance • An increase of three (3) additional residential drivers and trucks which is needed to shift from bi- weekly to weekly organics collection • Tipping fee increase at the CCWS/RCTS facility of $17.11 per ton for facility 1) recycling operations at MDR, 2) SB 1383 post collection processing costs, and 3) costs of new related buildings and infrastructure.2 MDRR operates under an exclusive franchise with the County to collect, and remove for disposal and recycling, residential, commercial, and light industrial solid waste, recyclable materials, and green waste (organics). On May 9, 1995, the County signed a twenty (20) year franchise agreement with MDRR. On August 9, 2011, the County approved the Third Amendment to the Franchise Agreement which extended the franchise term an additional ten (10) years through May 8, 2025 or until termination of the 3-cart system, whichever is shortest. The MDRR franchise includes the following six (6) service areas in unincorporated Contra Costa County (Exhibit 1 shows the location of each service area): 1. Bay Point 2. Brentwood, unincorporated 3. Byron 4. Discovery Bay 5. Bethel Island, Knightsen & Oakley, unincorporated 6. North Concord, unincorporated. MDRR consolidates refuse collected from unincorporated County areas at the Recycling Center and Transfer Station (RCTS) in Pittsburg, California. MDRR then transports the refuse to Keller Canyon Landfill (located in unincorporated Contra Costa County) for disposal. MDRR provides curbside recycling services to unincorporated County areas. Residential customers commingle their recyclable materials into one 96-gallon cart. MDRR collects residential curbside recyclables bi-weekly.3 MDRR takes recyclable materials to its RCTS facility where they are separated on a Materials Recovery Facility (MRF) sort line. MDRR also provides residential customers with bi-weekly green waste collection service. 2 Represents a $16.25 per ton increase in 2021 escalated by 1.59% in 2022 and 3.66% in 2023. 3 With the exception of customers located on Marsh Creek Road who currently place their recyclables out for weekly collection in special company issued blue bags. 730 Ms. Deidra Dingman Page 4 March 11, 2024 Exhibit 1 Unincorporated Contra Costa County Map of Mt. Diablo Resource Recovery Service Areas D. Goals and Objectives of Analysis The primary goal of this Analysis is to determine fair and equitable residential and commercial refuse charges that cover MDRR’s incremental new costs required to comply with SB 1383 requirements. MDRR’s Application is for an “extraordinary rate adjustment,” which the Manual describes as follows: “Special extraordinary rate applications are allowed outside of the annual schedules of the base year, interim year, and CPI adjustments. Both the County and the franchise hauler may initiate the extraordinary rate adjustment process. For these adjustments, the franchise hauler will provide necessary information and documentation so the County can make a judgment as to the reasonableness of such a rate adjustment. An extraordinary rate adjustment can only be implemented by the franchise hauler if approved by the Board of Supervisors and the required rate change notice has been provided to customers 30 days in advance. This extraordinary adjustment will only be considered in a case where the franchise hauler can demonstrate that a change in one of the cost line items specified in the Base Year Rate Change Application will exceed two (2) times the most recent change in the Consumer Price Index for the San Francisco-Oakland-San Jose area published by the Bureau of Labor Statistics.” Fairness is demonstrated through a detailed evaluation of MDRR actual revenues and projected expenses to comply with SB 1383 requirements. Residential charges also should be justifiable and 731 Ms. Deidra Dingman Page 5 March 11, 2024 supportable. Rate setting is prospective. The County sets rates in advance of when actual results occur. The County sets rates that are intended to cover MDRR’s costs of operations and allow a reasonable profit. The County uses the operating ratio (OR) method to project the profit level allowed to MDRR. The actual OR level, or profit, received by MDRR in a base year, and in subsequent interim years, is not however, guaranteed. E. Scope of Analysis The scope of work for this project is based on the Manual’s requirements for an “extraordinary rate adjustment,” within an interim year rate adjustment period. The scope of this Analysis included the following three (3) primary tasks: 1. Analyze MDRR’s SB 1383 Rate Request 2. Support County in discussions with MDRR 3. Prepare Draft and Final Reports. As part of this Analysis, we performed the following activities: • Determined whether the request and rate model is mathematically correct and complete • Assessed assumptions regarding incremental changes in routes, trucks, labor, operating costs, carts, profits, and franchise fees • Obtained documentation supporting baseline and incremental changes to MDRR’s costs (e.g., route data, number of drivers/laborers, truck and cart depreciation schedules, inventory reports, and purchase orders validating cost of new trucks/carts) • Evaluated changes in tipping fees at the RCTS required to process organics materials and to shift to including post-collection recyclables processing in the facility tip fee • Compared incremental SB 1383 implementation costs, provided by MDRR and others, experienced in similar jurisdictions • Identified adjustments to the company’s request, as necessary. F. History of Collection Rates Over the 24 years since the County implemented the Manual (1998 to 2021), County residential rate increases (shown in Table 3) averaged approximately 3.19 percent on a compounded basis (including rate increases for new programs). During this same timeframe the applicable CPI increased by approximately 2.91 percent on a compounded basis. 732 Ms. Deidra Dingman Page 6 March 11, 2024 Table 3 Unincorporated Contra Costa County Historical Mt.

SB 1383 Rate Application The County received MDRR’s SB 1383 Rate Change Application (Application) on October 13, 2023. A copy of the Application is provided in Attachment A at the end of this report.4 As shown in Table 4 this 4 Note that this application supersedes a prior SB 1383 application submitted in 2021 (provided in Attachment B). Additional time was needed to fully implement the associated SB 1383 facility and operational changes. 733 Ms. Deidra Dingman Page 7 March 11, 2024 request corresponds to a $10.93 per customer, per month, increase in the 64-gallon residential rate, the most common service level in the County franchise area.

Results of Analysis This section provides the analysis of MDRR’s Application. The impact of each adjustment is identified in terms of a dollar value increase or a decrease for each revenue and cost category shown in the Application. The adjusted rate model is provided in Attachment C. Revenue Requirement The revenue requirement is the amount of revenue that MDRR needs to collect, through rates charged to customers, to cover the costs of providing the service, plus a reasonable financial return. Increasing the revenue requirement results in an increase in rates and decreasing the revenue requirement results in a decrease in rates. The revenue requirement is equal to the sum of the following: • Total allowable costs • Allowable operating profits • Total pass through costs. MDRR’s requested incremental addition to the County revenue requirement for SB 1383, as submitted in the Application, was $1,814,294 (see Line 48 of the Application). The analysis of the Application resulted in an overall decrease of $514,173 to MDRR’s requested revenue requirement resulting in an adjusted 2024 revenue requirement of $1,300,121. The remainder of this subsection identifies and explains adjustments to MDRR’s 2024 projected revenues and costs. Revenues Residential Revenues (Line 1) MDRR projected 2024 residential revenues of $5,894,000. These revenues were adjusted from $5,894,000 to $6,302,987 based on annualizing ten months of actual MDRR provided 2021 residential revenue data and adjusting for approved rate changes in 2022 and 2023. • Net Impact: $408,987 increase in 2024 residential revenues. Commercial and Light Industrial Revenues (Lines 2 and 3) MDRR projected 2024 commercial and light industrial revenues of $2,335,000. These revenues were adjusted from $2,335,000 to $2,353,382 based on annualizing ten months of actual MDRR provided 2021 commercial and light industrial revenue data and adjusting for approved rate changes in 2022 and 2023. • Net Impact: $18,382 increase in 2024 commercial and light industrial revenues. 734 Ms. Deidra Dingman Page 8 March 11, 2024 Allowable Costs Residential and Commercial Drivers (Lines 6 and 7) MDRR projected an increase to its estimated incremental new driver costs of $517,000, reflective of: • An additional 3 residential drivers (equivalent to 3.0 FTEs) to support weekly versus bi-weekly organics hauling services, equal to an increase of $507,000 in salary, payroll taxes, and fringe benefits • An additional portion of a commercial driver (equivalent to a 0.06 FTEs) to support weekly versus bi- weekly organics hauling services, equal to a total of $10,000 in salary, payroll taxes, and fringe benefits. Driver labor was adjusted to reflect an incremental residential driver requirement of 2.0 FTEs rather than the 3.0 FTEs requested, which resulted in a decrease of $84,855. Assumptions related to the incremental 2.0 FTEs needed to move from residential bi-weekly to weekly service are provided in Table 5 below: Table 5 Mt. Diablo Resource Recovery Residential Organics Collection Changes from Current Bi-weekly to Weekly Service Area Current Number of Route Days (Every Other Week Service) Current Work Days (Every Other Week Service) New Work Days (Every Week Service) Incremental Change in Work Days (Every Week Service) Incremental Change in Full Time Equivalent Staff Bay Point 2 Drivers, 2 Days/ Every Other Week 104 Work Days5 208 Work Days 104 Work Days 0.5 FTE Brentwood 1 Driver, 4 Days/ Every Other Week 104 Work Days6 208 Work Days 104 Work Days 0.5 FTE Discovery Bay 3 Drivers, 2 Days/ Every Other Week 156 Work Days7 312 Work Days 156 Work Days 1.0 FTE Total 2.0 FTE • Net Impact: $84,723 decrease in 2024 direct labor costs.8 Depreciation and Other Operating Costs (Lines 9 to 14) MDRR projected an incremental increase in 2024 depreciation and other operating costs of $84,000 which reflects: • Projected annual outreach (cart labels) depreciation of $35,000 • Projected annual flyers and publications of $40,000 • Projected other compliance costs of $9,000. Net Impact: $397 decrease in 2024 depreciation and other operating costs (minor adjustment due to rounding). 5 Equals 2 drivers x 2 days per week x 26 weeks per year. 6 Equals 1 driver x 4 days per week x 26 weeks per year. 7 Equals 3 drivers x 2 days per week x 26 weeks per year. 8 Includes a $132 addition to commercial drivers (a minor rounding adjustment). 735 Ms. Deidra Dingman Page 9 March 11, 2024 Allowable Operating Profit (Line 26) MDRR’s projected 2024 allowable operating profit totaled $66,778, which reflects: • A 90 percent operating ratio, and • Projected $601,000 in total allowable costs. In accordance with the Manual, the calculation is based on a 90 percent operating ratio. MDRR’s projected 2024 operating profit was reduced from $66,778 to $57,320 based on the adjustments noted above to MDRR’s projected 2024 total allowable costs (i.e., from $601,000 to $515,880). • Net Impact: $9,458 decrease in 2024 allowable operating profit. Pass Through Costs Trucking and Equipment Costs MDRR’s projected incremental 2024 trucking and equipment costs totaled $897,000, which reflects: • An increase by 3.00 residential trucks totaling $880,000 • An increase by 0.06 commercial trucks totaling $17,000. MDRR’s assumption regarding the total number of new incremental residential trucks was reduced from 3.0 to 2.0 to align with the driver’s 2.0 FTE allocation to support weekly organics collection services (shown in Table 5). This change in MDRR’s allocation basis decreased the 2024 projected trucking and equipment costs from $897,000 to $604,107. • Net Impact: $292,893 decrease in 2024 trucking and equipment costs. Tipping Fees MDRR’s projected incremental new 2024 tipping fees (pass-through) costs totaled $352,000, which reflects: • Projected increase in the cost of recycling processing at the Recycling Center & Transfer Station (RCTS) of $141,0009 • Projected increase in SB 1383 post collection efforts at the RCTS of $92,000 • Projected increase to account for capitalizing the costs of an upgraded SEG mechanics shop at the RCTS of $16,000 • Projected increase to account for capitalizing the costs of a new organics processing facility (building and infrastructure) at the RCTS of $103,000. MDRR’s projection for these item was reduced to correct for an incorrect calculation. The Application incorrectly included costs for a different jurisdiction (a neighboring city) rather than those for the County- served areas. Additionally, we adjusted the operating ratio applied to these new tipping fees to 90 percent from the 85 percent level included by MDRR in the Application. These two adjustments resulted in an overall decrease of $90,710. • Net Impact: $90,710 decrease in 2024 tipping fee costs. Franchise Fees The County franchise agreement with MDRR specifies that the County can establish an amount equal to “a percentage of Contractor’s [MDRR’s] Gross Annual Revenues” with the “amount, time and frequency of 9 Note: this represents a change in how the company accounts for processing recycled materials at the MRF. As a consequence, this new cost item is offset by removing the cost of processing materials at the MRF under the current methodology which was equal to $246,757 (see Line 32 of the application where this is shown as an offset to the incremental new costs). 736 Ms. Deidra Dingman Page 10 March 11, 2024 payment of such fees established by the County.” The franchise fee paid by MDRR to the County is currently equal to seven (7) percent of gross revenues. Gross revenues include residential, commercial, and light industrial refuse and recycling revenues. Franchise fees are a pass-through expense, which do not earn profit. MDRR’s projected incremental 2024 franchise fees were reduced from $144,274 to $108,281 based on the adjustments to MDRRs projected 2024 costs noted above. • Net Impact: $35,992 decrease in 2024 franchise fees.

In the Application, MDRR proposed to increase unincorporated County collection rates by 22.05 percent in 2024. The Application modified MDRR’s original SB 1383 application submitted in 2022 (shown in Attachment B). The changes from the 2022 application to this 2024 Application include: • Adjusted for the impact of an approved rate increase of 3.15% residential/7.15% commercial in 2022 • Adjusted for the impact of an approved rate increase of 5.00% in 2023 • Removal of pail, lid, and cart depreciation • Adjusted for CPI based adjustments to applicable allowable and pass through costs in 2022 (5.90%) and 2023 (2.88% • Removal of the CPI based increase (Line 50, already granted through rate changes noted above). 740 Ms. Deidra Dingman Page 14 March 11, 2024 741 Ms. Deidra Dingman Page 15 March 11, 2024 Attachment B: Initial SB 1383 Rate Application (2022) 742 Ms. Deidra Dingman Page 16 March 11, 2024 Attachment B includes a 2022 application submitted by MDRR to the County. In this application, MDRR proposed to increase unincorporated County collection rates by 26.88 percent in 2024. MDRR used year- to-date information to estimate 2021 financial results. Year 2022 results were entirely projected in the Application. MDRR requested a 26.88 percent rate increase effective for 2022, inclusive of a 23.07 percent increase for SB 1383 requirements and a 3.81 percent CPI increase. The Application cited the following primary drivers for the rate increase request: • Capital costs for SB 1383 requirements – kitchen pails, replacement of commercial bin lids, new carts, container labels, customer outreach, and regulatory compliance - $910,598 ($178,133 annual costs) • An increase of three (3) additional residential drivers and trucks which is needed to shift from bi- weekly to weekly organics collection • Tipping fee increase at the CCWS/RCTS facility of $16.25 per ton to cover the following facility changes: 1) changes to recycling operations at MDRR, 2) SB 1383 post collection processing costs, and 3) new related buildings and infrastructure. 743 Ms. Deidra Dingman Page 17 March 11, 2024 744 Ms. Deidra Dingman Page 18 March 11, 2024 745 Ms. Deidra Dingman Page 19 March 11, 2024 746 Ms. Deidra Dingman Page 20 March 11, 2024 747 Ms. Deidra Dingman Page 21 March 11, 2024 748 Ms. Deidra Dingman Page 22 March 11, 2024 Attachment C: Adjusted SB1383 Rate Model 749 Ms. Deidra Dingman Page 23 March 11, 2024 Line Total MDRR Application Total Adjustments Total Adusted Residential Service 1 5,894,000$ 408,987$ 6,302,987$ Commercial Service 2 1,631,000 150,140 1,781,140 Debris Box 3 704,000 (131,758) 572,242 Total Commercial Revenue 4 2,335,000$ 18,382$ 2,353,382$ Total Revenue 5 8,229,000$ 427,369$ 8,656,369$ Additional Residential Drivers 6 507,000$ (84,855)$ 422,145$ Additional Commercial Drivers 7 10,000 132 10,132 Additional Drivers 8 517,000 (84,723) 432,277 Pail Depreciation 9 -$ -$ -$ Lid Depreciation 10 - - - Cart Deprecation 11 - - - Total Outreach - Label Depreciation 12 35,000 (297) 34,703 Total Outreach - Flyers & Publications 13 40,000 (224) 39,776 Total Compliance Costs 14 9,000 124 9,124 Total Other 1383 Costs 15 84,000$ (397)$ 83,603$ Total Allowable Costs 16 601,000$ (85,120)$ 515,880$ Operating Profit 17 66,778 (9,458) 57,320 Operating Ratio %18 90.0%0.0%90.0% Total Allowable Costs + Profit 19 667,778$ (94,578)$ 573,200$ Additional Residential Truck(s)20 880,000$ (293,083)$ 586,917$ Additional Commercial Truck(s)21 17,000 190 17,190 Total Trucks 22 897,000$ (292,893)$ 604,107$ Cost of Recycling 23 141,000$ (38,226)$ 102,774$ 1383 Post Collection 24 92,000 (23,484) 68,516 SEG - Mechanic Shop @ RCTS 25 16,000 (3,000) 13,000 Phase 2 - Organics Building & Infrastructure 26 103,000 (26,000) 77,000 Total Tip Fee Increase 27 352,000$ (90,710)$ 261,290$ -$ Total Pass Through Costs 28 1,249,000$ (383,603)$ 865,397$ - Total Costs + Profit 29 1,916,778$ (478,181)$ 1,438,597$ -$ Contra Costa County Franchise Fee @ 7%30 144,274$ (35,992)$ 108,281$ -$ -$ -$ Total Costs + Profits + Franchse Fees 31 2,061,051$ (514,173)$ 1,546,878$ -$ Minus 2019 Base Rate - Recycling Calculations 32 (246,757) - (246,757) -$ Total Additional Revenue 33 1,814,294$ (514,173)$ 1,300,121$ Total Revenue Based on CPI 34 -$ -$ -$ Total Addiitonal Revenue Requirement with CPI 35 1,814,294$ (514,173)$ 1,300,121$ Commercial & Residential Increase before CPI Adj 36 22.05%-7.03%15.02% 2021 CPI Increase 37 0.00%0.00%0.00% 38 0.00%0.00%0.00% Total Residential & Commercial Increase (Scenario 1)39 22.05%-7.03%15.02% Rate Increases 2021 RevenueAllowable CostsPass-Through CostsOther Adjustments750 Ms. Deidra Dingman Page 24 March 11, 2024 Attachment D: Summary Comparison of Other Jurisdictions’ SB 1383 Rate Changes 751 Ms. Deidra Dingman Page 25 March 11, 2024 Crowe did some research on the rate impacts of implementing SB 1383 in jurisdictions throughout California. The general expectation was for households to see a rate increase of between $3 and $5 per customer, per month with the average increase for businesses of between $70 and $90 per month. The League of California Cities reported a potential range of between 1 and 20 percent. The large range in rate changes is primarily driven by whether facility changes are required and to what degree collection routing/operations change. A total of nineteen (19) recent published examples of SB 1383 rate changes throughout California are listed below10: • City of Beaumont – 15.4% • City of Campbell – 9.9% • City of Claremont – 6.5% • City of Citrus Heights – 26% • City of Elk Grove – 23% • City of Encinitas - $3.88 per residential customer, per month • City of Folsom – 34.1% • City of Industry - $2.45 per residential customer, per month • City of Lake Forest – 25% • City of Los Gatos – 9.9% • City of Monte Sereno – 9.3% • City of Napa – 6% • City of Pacifica – 5.5% • City of Rolling Hills Estates – 6.3% • City of Santa Clara – 16% • City of Saratoga – 9.5% • City of Sacramento – 27% (implementation spread over 3 years) • City of Vacaville – 4.2% • City of Walnut – 9.36%. For the 17 jurisdictions with a percent change noted above, these rate changes ranged from 4.2 to 34.1 percent with an average of just over 14 percent. 10 These rate changes represent almost entirely the impacts of SB 1383, with some minor portions of these rate changes associated with other changes unrelated to SB 1383. 752 753
