Costa
County
Subject:Temporary Hire of a County Retiree and Waiver of the 180-Day "Sit-Out Period" for the Assessor's Office
BACKGROUND: (CONT'D)
retirement before returning to work as a temporary employee. The Act also allows the Board, based on a finding that the appointment is
necessary to fill a critically needed position, to waive the 180 day "sit-out" period.
Mr. Sueoka retired from County service on March 31, 2022. He was hired in the Assessor's Office 26 years ago and when he retired, he had
over 15 years of experience as an Associate Appraiser, with nearly all of his experience in the Residential Division. As an Associate Appraiser,
Mr. Sueoka was responsible for the more complex appraisals, resolving assessment appeals and challenging valuation issues, making change in
ownership determinations, analyzing ownership issues, and investigating and researching property tax matters for the Alamo and Diablo areas.
The Division’s current workload is greater than prior roll years due to an increase in sales and new construction throughout the County. In
addition to the increase of work, the Division was required to allocate staff to assist with increased workloads in other Divisions and suffered a
sudden and unexpected loss of staff due to a resignation and two retirements.
Mr. Sueoka is experienced and qualified to perform the necessary tasks to ensure the Department meets the State's requirement to deliver the
assessment roll by July 1, 2022. Due to staff shortages and an increased workload, the Department would like to hire Mr. Sueoka as a temporary
employee from April 27, 2022 through June 30, 2022 to assist in the close of the assessment roll.
CONSEQUENCE OF NEGATIVE ACTION:
Failure to receive Board approval will create additional strain on existing staff in the Residential Division and could increase the risk that the
Department will be unable to certify the assessment roll by the State’s deadline of July 1, 2022.
RECOMMENDATION(S):
1. CONSIDER waiving the 180-day 'sit-out period' for Mr. Dave Duet, Facilities Manager, in the Health Services Department;
2. FIND that the appointment of Mr. Duet is necessary to fill a critically needed position; and
3. APPROVE and AUTHORIZE the hiring of retiree Mr. Dave Duet as a temporary employee effective May 1, 2022, through April 30, 2023 as
recommended by the Health Services Director.
FISCAL IMPACT:
Upon approval, this action will have an annual cost of $59,558 which is already included in the Department's operating budget. (100% Hospital
Enterprise Fund I)
BACKGROUND:
Dave Duet retired from County service on March 30, 2022. Mr. Duet has been with Health Services' Contra Costa Regional Medical Center
(CCRMC) for almost 22 years, with the majority of his time serving as the CCRMC Facilities Manager. It is essential that he return as a retiree
to provide continuity of services until his replacement is hired. The Department is in preparation of the recruitment process in order to establish
an employment list and permanantly fill the position.
The Department has determined that it is necessary for Mr. Duet to return as the Facilities Manager. In or about August 2022, CCRMC is
scheduled for two major inspections from the Joint Commission and the California Department of Health Care Services (DHCS) facility
relicensing inspection. Both inspections are heavily focused on the environment of care which includes safety, security, and plant operations. As
a retiree, Mr. Duet will continue to serve as CCMRC's Facilities Manager and play a central role in both inspections. Mr. Duet will serve as the
Safety Officer for the hospital and health centers, maintain the Emergency Operations Plan, and oversee the emergency management disaster
drills. In addition, he will continue to oversee the environmental services (EVS) units at CCRMC and Health Centers; monitor the Public Works
and DoIT work orders and projects; review and submit capital projects; and serve as liaison with Public Works and the various trades and
contractors.
CONSEQUENCE OF NEGATIVE ACTION:
Failure to receive Board approval may adversely impact CCRMCs regulatory and facility licensing inspections from CDPH and the Joint
Commission.

practice and HIV clinics.
The department requests to hire Dr. Farnitano as a retiree to staff the family practice and HIV clinics in the County's Pittsburg
Health Center.

B. General Plan: The subject property’s General Plan land use designation is PS. The PS designation includes properties owned by
public governmental agencies such as libraries, fire stations, schools, etc., and privately-owned transportation and utility corridors (e.g.,
railroads, pipelines).
C. Zoning: The subject property is located in the Rodeo Planned Unit District (P-1). Land uses in the Rodeo P-1 are dictated by the
property’s General Plan land use designation.
County Planning Commission Hearing
On February 9, 2022, the County Planning Commission (CPC) conducted a hearing on the proposed General Plan amendment. The CPC
voted unanimously (7-0) to recommend adoption of the GPA to the Board of Supervisors, with a modification that the new land use
designation be Multiple-Family Residential-Medium Density (MM) instead of the applicant's requested MH. This would reduce the
maximum unit yield of the property from four units down to three. The CPC was concerned with neighborhood compatibility, specifically
that future development of a four-unit building would be too tall and inconsistent with the surrounding community, as the height limit for
properties designated MH is 45 feet in the Rodeo P-1 zoning district. The topic of height limits and other applicable Rodeo P-1
development standards is discussed further under the "Staff Analysis" section below.
Environmental Review
The proposed GPA is exempt from the provisions of the California Environmental Quality Act. Per section 15061(b)(3) of the CEQA
Guidelines, a project is exempt from CEQA if the activity is covered by the "common sense" exemption that CEQA applies only to projects
which have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility
that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA.
The potential development allowed by the GPA would not result in significant environmental impacts because of its location within a fully
developed existing neighborhood, low unit yield, and infill characteristics. For example, air quality, greenhouse gas, and traffic impacts
would be typical of a small multi-family project in an urbanized area, i.e., negligible. Noise impacts would also be negligible, as the
surrounding area is a built-out residential and commercial environment and potential development would be consistent with that kind of
development.
Being a developed neighborhood, there also is no sensitive habitat that could be disturbed by development. Additionally, the property
receives public utilities and is not the type of development associated with hazardous materials. Therefore, it can be seen with certainty that
there is no possibility that the activity in question may have a significant effect on the environment.
Furthermore, under CEQA Guidelines Section 15303(b), multi-family buildings that include up to six dwelling units and are located in
urbanized areas are categorically exempt from environmental review.
Staff Analysis
The proposed project involves a GPA to change the General Plan land use designation from PS to MH for a 5,750 square-foot (0.13-acre)
vacant parcel. The subject property was previously owned by the County and was purchased at auction by the current owners.
The new property owner is interested in developing the site with a small multi-family project. It is noted that adjacent parcels are developed
as single-family residences, a four-plex, offices, and commercial shops. The applicant has stated their intention to develop the property to its
maximum potential while still maintaining compatibility with the development pattern in the community. As such, the applicant is
requesting the MH land use designation, which has a density range of 22.0-29.9 units per net acre. This density translates to a range of three
to four units on the subject property. The MH land use designation is consistent with the overall residential character of the community and
numerous other examples of MH designations with multi-family development are present nearby.
Rodeo P-1 zoning requires a minimum lot size of 10,000 square feet for multi-family development, 6,000 square feet for a duplex, and
2,800 square feet for a single-family residence. Although it does not meet the minimum lot size for the P-1, the size of the property would
not preclude development of up to four units. This is evidenced by multiple properties within the vicinity having similarly sized lots with
multi-family buildings on them, including a four-plex directly adjacent to the south.
The height limit for properties designated MH in the Rodeo P-1 is 45 feet, which allows significant vertical room to accommodate potential
units, off-street parking, and outdoor space for the tenants. As indicated above, the CPC's recommendation for modifying the GPA from
MH to MM was in response to the potential for future development of four units to be built up to the 45-foot height limit of the Rodeo P-1.
Since the MM designation has the same height limit of 45 feet, the reduction of units does not necessarily achieve the intended height
reductions; it may simply reduce the chances of a taller building being constructed. A multi-family project adhering to the P-1 development
standards can be developed on the subject property if designed properly.
Staff notes that the adjacent four-unit building to the south is less than 30 feet tall. Staff also notes that the subject property is at a lower
base elevation than the adjacent single-family neighborhood to the west, so while the height limit for a property designated MH or MM is 10
feet taller than the adjacent single-family neighborhood, the difference is largely offset by topography.
Considering Contra Costa County's 6th Cycle Regional Housing Needs Allocation (RHNA) of 7,610 units, 58.8 percent of which must be
below market rate, changing the land use designation to MH is, from staff's perspective, preferable to MM. While none of the units
resulting from the GPA are required by ordinance to be affordable, they will be more affordable by design. The reduction in density from
MH to MM would not necessarily achieve the intended height reduction and would only serve to eliminate a housing opportunity when the
County needs a substantial influx of housing.
Conclusion
Changing the land use designation to MH is consistent with the goals and policies of the General Plan, and the overall development pattern
of the Rodeo community. Therefore, staff recommends that the Board of Supervisors adopt the requested GPA pursuant to the
recommendations listed above in this staff report.
CONSEQUENCE OF NEGATIVE ACTION:
The subject property will retain its PS land use designation if the proposed GPA is not adopted. The PS designation is intended for land
owned by public agencies and other entities serving the public, but the property is now under private ownership. Retaining the PS
designation would severely limit opportunities for future development and preclude the project applicant from realizing their ultimate goal
of constructing housing.

Resolution No. 2022/116
IN THE MATTER OF approving a General Plan Amendment (County File #GP20-0003) for the 343 Rodeo Avenue General
Plan Amendment project.
WHEREAS, the Contra Costa County Board of Supervisors held a public hearing on April 26, 2022, to consider the 343 Rodeo
Avenue General Plan Amendment project, proposed for the Rodeo area. The project includes adoption a California
Environmental Quality Act (CEQA) finding that the project is exempt from CEQA pursuant to CEQA Guidelines sections
10561(b)(3) and 15303(b), and adoption of a General Plan Amendment (County File #GP20-0003).
WHEREAS, the General Plan Amendment changes the subject property's General Plan Land Use Element Map designation from
Public and Semi-Public (PS) to Multiple-Family Residential-High Density (MH).
WHEREAS, a resolution is required under Government Code Section 65356 to amend a General Plan.
NOW, THEREFORE, the Contra Costa County Board of supervisors resolves as follows:
A. The Board of Supervisors makes the following General Plan Amendment (GPA) findings:
The subject site is located inside the County’s Urban Limit Line (ULL), and therefore may be developed with “urban” or
“non-urban” uses, as defined in the 2005-2020 Contra Costa County General Plan. The proposed land use designation,
Multiple-Family Residential-High Density (MH), is urban. Furthermore, the project does not involve expansion of the
ULL or extension of urban services beyond the ULL boundary, thereby being consistent with General Plan Land Use
Element Policy 3-10, which discourages such extensions.
1.
Adoption of the proposed GPA will not cause a violation of the 65/35 Land Preservation Standard (the “65/35 Standard”),
originally approved by County voters through adoption of Measure C-1990 and reaffirmed through adoption of Measure
L-2006. Under the 65/35 Standard, no more than 35 percent of the land in the County may be developed with urban uses
and at least 65 percent of the land must be preserved for non-urban uses such as agriculture, open space, parks, wetlands,
etc. The existing land use designation for the subject site, Public and Semi-Public (PS), is a non-urban designation. As the
proposed MH land use designation is an urban designation, there will be a fractional increase in the percentage of land
devoted to urban uses. The increase will not result in exceedance of the 35 percent limit.
2.
The project complies with the objectives and requirements of Measure J-2004, the Contra Costa Transportation Authority
(CCTA) Growth Management Program, and related CCTA resolutions. Adoption of the proposed GPA would increase the
subject site’s maximum development potential from a variety of public and semi-public land uses, excluding residential
development, to up to four multiple-family residential units. The increase is below the threshold for triggering the Growth
Management Program GPA Review Process or studying the proposed GPA’s potential impacts on Routes of Regional
Significance.
3.
The General Plan comprises an integrated, internally consistent, and compatible statement of policies governing
development in the unincorporated area of the county. The proposed GPA affects only the Land Use Element Map. The
proposed GPA involves an increase in density at the subject site that is consistent with the goals and policies for the Rodeo
area, as well as the overarching goals and policies of the General Plan related to land use, growth management,
transportation, housing, noise, conservation, open space, and safety. Adoption of the proposed GPA will not cause the
General Plan to become internally inconsistent.
4.
General Plan to become internally inconsistent.
Pursuant to Government Code Section 65358(a), the General Plan may be amended if such amendment is deemed to be “in
the public interest.” The General Plan contains policies related to providing an adequate housing supply and encouraging
infill development on under-utilized sites within urbanized areas where necessary utilities already are installed. It is in the
public interest to adopt the proposed GPA because the project is consistent with these policies and will allow for an
increase in housing supply with insignificant environmental impacts. Not only would adoption of the GPA allow for
additional housing units, but development of under-utilized sites also serves to prevent blight, as the vacant lot will no
longer be available for illegal dumping or other potential neglect.
5.
Pursuant to Government Code Section 65358(b), no mandatory element of the General Plan may be amended more than
four times per calendar year. The proposed GPA affects the Land Use Element, a mandatory element, and is part of the first
consolidated amendment of the Land Use Element for 2022.
6.
B. The Board of Supervisors hereby ADOPTS the General Plan Amendment, County File #GP20-0003, to change the land use designation of the subject property from Public and
Semi-Public (PS) to Multiple-Family Residential-High Density (MH) as part of the first consolidated General Plan Amendment for calendar year 2022, as permitted by State Planning
Law.

FINDINGS AND CONDITIONS OF APPROVAL FOR ASHUR ABBASI (APPLICANT & OWNER);
COUNTY FILE #GP20-0003
FINDINGS
A. General Plan Amendment
1. Required Finding: Adoption of the proposed General Plan Amendment will not violate
the County Urban Limit Line.
Project Finding: The subject site is located inside the County’s Urban Limit Line (ULL),
and therefore may be developed with “urban” or “non-urban” uses, as defined in the
2005-2020 Contra Costa County General Plan. The proposed land use designation,
Multiple-Family Residential-High Density (MH), is urban. Furthermore, the project does
not involve expansion of the ULL or extension of urban services beyond the ULL
boundary.
2. Required Finding: Adoption of the proposed General Plan Amendment is consistent
with the 65/35 Land Preservation Standard.
Project Finding: Adoption of the proposed General Plan Amendment (GPA) will not
cause a violation of the 65/35 Land Preservation Standard (the “65/35 Standard”),
originally approved by County voters through adoption of Measure C-1990 and
reaffirmed through adoption of Measure L-2006. Under the 65/35 Standard, no more
than 35 percent of the land in the County may be developed with urban uses and at
least 65 percent of the land must be preserved for non-urban uses such as agriculture,
open space, parks, wetlands, etc. The existing land use designation for the subject site,
Public and Semi-Public (PS), is a non-urban designation. As the proposed MH land use
designation is an urban designation, there will be a fractional increase in the
percentage of land devoted to urban uses. The increase will not result in exceedance
of the 35 percent limit.
3. Required Finding: The proposed General Plan Amendment is consistent with the
Contra Costa Transportation Authority Growth Management Program.
Project Finding: The project complies with the objectives and requirements of
Measure J-2004, the Contra Costa Transportation Authority (CCTA) Growth
Management Program, and related CCTA resolutions. Adoption of the proposed GPA
would increase the subject site’s maximum development potential from a variety of
public and semi-public land uses, excluding residential development, to a range of
three-to-four multiple-family residential units. The increase is below the threshold for
triggering the Growth Management Program GPA Review Process or studying the
proposed GPA’s potential impacts on Routes of Regional Significance.
4. Required Finding: Following adoption of the proposed General Plan Amendment, the
General Plan will remain internally consistent, as required under Government Code
Section 65300.5.
CPC – February 9, 2022
County File #GP20-0003
Findings & COAs Page 2 of 4
Project Finding: The General Plan comprises an integrated, internally consistent, and
compatible statement of policies governing development in the unincorporated areas.
The proposed GPA affects only the Land Use Element Map. The proposed GPA involves
an increase in density at the subject site that is consistent with the goals and policies
for the Rodeo Area, as well as the overarching goals and policies of the General Plan
related to land use, growth management, transportation, housing, noise, conservation,
open space, and safety. Adoption of the proposed GPA will not cause the General Plan
to become internally inconsistent.
5. Required Finding: Adoption of the proposed General Plan Amendment is in the public
interest, as required under Government Code Section 65358(a).
Project Finding: Pursuant to Government Code Section 65358(a), the General Plan
may be amended if such amendment is deemed to be “in the public interest.” The
General Plan contains policies related to providing an adequate supply of housing and
encouraging infill development on under-utilized sites within urbanized areas where
necessary utilities already are installed. It is in the public interest to adopt the proposed
GPA because the project is consistent with these policies and will allow for an increase
to the supply of housing units. Not only would this allow for additional housing units,
development of under-utilized sites also serves to prevent blight, as the vacant lot will
no longer be available for illegal dumping or potentially neglected by a property
owner.
6. Required Finding: Adoption of the proposed General Plan Amendment would not
exceed the limit on such amendments specified under Government Code Section
65358(b).
Project Finding: Pursuant to Government Code Section 65358(b), no mandatory
element of the General Plan may be amended more than four times per calendar year.
The proposed GPA affects the Land Use Element, a mandatory element, and is the first
consolidated amendment of the Land Use Element for 2022.
B. Growth Management Performance Standards
1. Traffic: Implementation Measure 4-c of the Growth Management Element of the
General Plan requires a traffic impact analysis of any project that is estimated to
generate 100 or more additional AM or PM peak-hour trips. The proposed land use
designation would allow for three-to-four new multi-family residential units on the
subject property, and the property is accessed directly from Rodeo Avenue. The new
density of up to four units would not generate an increase in AM or PM peak-hour
trips in excess of the 100-trip threshold. Thus, there would be no impact to area streets
or intersections and no traffic report is required.
2. Water: The project site currently receives water service from the East Bay Municipal
Utility District (EBMUD). Any future development shall be submitted to and reviewed
CPC – February 9, 2022
County File #GP20-0003
Findings & COAs Page 3 of 4
by EBMUD, and, by meeting their development standards, the site is expected to be
accommodated by existing water facilities and supplies without expansion of the
existing system. Accordingly, the impact of providing water service to the proposed
project would be less than significant.
3. Sewage: The project site is served by the Rodeo Sanitation District (RSD). Any future
development shall be submitted to and reviewed by RSD. By meeting their
development standards, the proposed project is expected to be accommodated by
existing RSD facilities without expansion of the wastewater treatment system. Thus, no
significant impacts related to the wastewater treatment requirements of the Regional
Water Quality Control Board for the San Francisco Bay Region would be expected.
4. Fire Protection: Fire protection and emergency medical response services for the
project vicinity are provided by the Rodeo-Hercules Fire Protection District (RHFPD).
The closest fire station to the subject property is Station #75 located approximately 0.2
miles away at 326 3rd Street, in Rodeo. Any future development shall be submitted to
and reviewed by RHFPD. As a result of compliance with RHFPD development
standards, there would be no significant increase in demand for fire services expected
as a result of the project.
5. Public Protection: Law enforcement services in the project vicinity are provided by the
Contra Costa County Sheriff’s Office, through the Bay Station, located approximately
8.1 miles driving distance to the southwest of the project site. Public protection
standards under Policy 4-6 of the Growth Management Program (GMP) of the County
General Plan require a Sheriff facility standard of 155 square feet of station area and
support facilities per 1,000 in population shall be maintained within the
unincorporated area of the county. The proposed project would not induce a
significant population increase within the county that would equal or exceed 1,000
persons. The new MH land use designation would allow for the future development of
up to four multi-family units, which would directly increase the Rodeo area population
by an estimated 11-12 people, based on the Census 2020 estimate of 2.87people per
household for Contra Costa County. Therefore, there would not be a significant
increase in need for police services.
6. Parks and Recreation: As the project will add to the County’s population if
development occurs, the future development would be required to pay applicable park
fees per unit. The Park Impact fee collected will be used for acquisition of parkland and
development of parks and recreational facilities. The Park Dedication ordinance allows
the developer of land for residential use to dedicate land, pay an in-lieu fee, or a
combination of both for neighborhood and community park or recreational purposes.
7. Flood Control and Drainage: The site is located in FEMA-designated Flood Zone AE. If
development occurs in the future, the project would be reviewed by the Public Works
Department to ensure compliance with all flood control and drainage ordinances and
requirements.

FISCAL IMPACT:
The Mariposa Energy Project Community Benefit Fund (Mariposa Fund) has covered consultant costs and most Department of
Conservation and Development (DCD) staff cost associated with this project. Originally, $349,270 from the Mariposa Fund was allocated to
this project. As amended, the contract with Dudek, the County's CEQA consultant, is for $272,586, to be paid out of the Mariposa Fund. The
remaining amount of $76,684 was intended to cover staff time; however, on July 13, 2021, the Board of Supervisors allocated an additional
$140,000 from the Mariposa Fund to this project to cover the significant cost of staff time invested into this project, resulting in a new total
allocation of $489,270. The Land Development Fund covered a small portion of DCD staff costs.
BACKGROUND:
Summary
The proposed project is a County-initiated General Plan Amendment (GPA), Development Plan Modification (DPM), Rezone, and Airport
Land Use Compatibility Plan (ALUCP) Amendment for the Byron Airport to expand the range of uses allowed on the airport property to
improve the airport's economic viability. The proposed GPA would include revised policies that update and clarify the range of land uses
and activities allowed at Byron Airport, similar to those already adopted for the County’s other general aviation airport, Buchanan Field in
Concord, as well as redesignation of an 11.7-acre parcel to be acquired by the County from AL to PS. The current Development Plan for
the airport would be modified to permit all of the new uses either by-right or with approval of a land use (conditional) permit. The DPM
would also establish certain development standards, such as maximum building heights, maximum floor area, landscaping requirements,
etc. The rezone would change the 11.7-acre parcel from A-3 to P-1 to be part of the Byron Airport Development Program. The ALUCP
would be updated with new policies and maps specific to Byron Airport, which would reflect the 2016 Airport Layout Plan for Byron
Airport, the 2005 Byron Airport Master Plan, and guidance set forth in the most recent version of the Caltrans California Airport
Land Use Planning Handbook.
Site/Area Information
A. General Plan: The subject site’s General Plan land use designations include Public and Semi-Public (PS), Open Space (OS), and
Agricultural Lands (AL). The PS designation includes properties owned by public governmental agencies such as libraries, fire stations,
schools, etc. The OS designation includes publicly-owned open space lands which are not designated as Public and Semi-Public,
Watershed, or Parks and Recreation. Lands designated Open Space include, without limitation, wetlands and tidelands and other areas of
significant ecological resources, or geologic hazards. OS also includes privately-owned properties for which future development rights have
been deeded to a public agency or private entity, such as a land trust. The primary purpose of the AL designation is to preserve and protect
lands capable of and generally used for the production of food, fiber, and plant materials.
The proposed project is located primarily within the PS designation, in which public airports are a compatible use. The existing aviation
facilities and the master-planned development areas are designated as PS. The proposed project includes redesignation of the 11.7-acre
parcel from AL to PS, which, after its redesignation, would result in the entire project being located within the PS designation. The
remainder of the airport property is designated OS, consistent with the habitat management use for the non-developable airport property.
B. Zoning: Byron Airport is zoned Planned Unit District (P-1); the 11.7-acre parcel is zoned Heavy Agricultural District (A-3).
C. Existing Site Condition: Byron Airport is located in southeastern Contra Costa County. The airport property consists of 1,427
acres, including 1,307 acres south of Armstrong Road and 120 acres north of Armstrong Road. The proposed Byron Airport Development
Program site excludes the 120 acres north of Armstrong Road, but includes an 11.7-acre parcel located between the airport property and the
Bethany Irrigation District Canal, for a total of approximately 1,319 acres. The project site includes the existing airport facilities and areas
proposed for development (referred to as the development area). However, most of the project site is reserved for habitat management.
Byron Airport's existing development footprint is small compared to the County's other airport, Buchanan Field. The facility has two
nonintersecting runways, each with a parallel taxiway and several connector taxiways. General aviation facilities are generally concentrated
in the west-facing “V” formed by the two runways and include aircraft surface storage, runway apron, hangars, and office space. Byron
Airport does not have a control tower. Significant buildings include the 2,400-square-foot administration building (500 Eagle Court), a
7,500-square-foot maintenance hangar (505 Eagle Court), the Byron Jet Center (760 Osprey Court), and two executive hangars. Other
aircraft storage consists of T-hangars and tie-downs. Accessory facilities include a wash rack, fuel farm, and 300-square-foot pump house
for fire protection. A small building on the north side of the airport (6900 Falcon Way) was part of the original Byron Airpark and is
currently leased to Bay Area Sky Diving.
Electrical power is supplied by Pacific Gas & Electric Company via Holey Road. There is no natural gas service at the airport. The on-site
water system consists of a domestic well with a 4,000-gallon holding tank, booster pump, and chlorinator; however, this water supply is
non-potable. Drinking water is provided by bottled water deliveries. The sanitary system consists of a 3,000-gallon septic tank and lift
station that pumps to a leach field located southwest of the aircraft apron.
D. Surrounding Land Use: Byron Airport is located on the western edge of the Central Valley. Byron Hot Springs, a now abandoned
resort and former World War II prisoner-of-war camp, is located north of the airport. Agricultural and rural residential uses border the east
and west sides of the airport property. To the south are agricultural lands and property owned by East Bay Regional Park District. Nearby
communities include Byron, approximately 2.5 miles north, Discovery Bay 4 miles to the northeast, and Mountain House, approximately 4
miles southeast.
Background
The original Byron Airport Master Plan (Airport Master Plan) was adopted in 1986, and the airport opened in 1994. The Airport Master
Plan was updated in 2005 and identifies a 20-year plan to support aviation activities at the airport. The 2005 Airport Master Plan also
identifies potential development opportunities on airport property to increase airport revenue and achieve economic self-sufficiency. In
2015, the County identified a suite of proposed land uses for development on airport property, building on the framework of the 2005
Airport Master Plan. The uses included aviation reserve land uses, which would be directly associated with aircraft operations (e.g., hangar
development, aircraft repair and maintenance), and airport-related land uses, which would not be aeronautical uses but would be compatible
with on-going aircraft operations.
The County’s existing General Plan policies, zoning regulations, and ALUCP policies specific to the airport do not accommodate many of
the proposed land uses. Therefore, the County’s Department of Conservation and Development and Public Works Department – Airports
Division are working collaboratively to amend the General Plan, zoning, Development Plan, and ALUCP to enable on-site development in
accordance with the Airport Master Plan.
The project would provide for both aviation development and non-aviation (airport-related) development. Aviation uses include aircraft
storage, administrative facilities, instructional facilities, fixed base operators, pilot and passenger terminal improvements, cargo facilities,
and aircraft repair and service. Non-aviation development includes a wide range of industrial, commercial, and office uses that benefit from
proximity to the airport and the regional roadway network. These uses may include warehousing and distribution; light manufacturing;
research and development; regional retail, including construction materials and home goods; service commercial; and offices. Local retail
and food service may also be provided to serve the airport and local residents.
Project Description
A. Objectives: The County identified the following project objectives:
1. Develop airport facilities to support the types of development envisioned in the 2005 Airport Master Plan.
2. Achieve economic self-sufficiency of the airport through development of airport-related land uses.
3. Protect current and future airport operations from incompatible land uses.
4. Provide a streamlined planning framework for future development consistent with the General Plan and ALUCP.
B. General Plan Amendment: The County General Plan designates the existing aviation facilities and the master-planned development
areas as Public and Semi-Public (PS). The remainder of the airport property is designated as Open Space (consistent with the habitat
management use for the non-developable airport property). The General Plan designation for the existing airport property will not change.
The 11.7-acre acquisition parcel would be redesignated from Agricultural Lands (AL) to PS to be consistent with the rest of the developable
airport property (see Attachment D, General Plan Amendment Map).
General Plan Policy 5-66 states, “Establishment of commercial, industrial, or residential development around the planned airport shall not
be allowed.” This policy would be amended to specify that commercial or industrial development would be allowed on airport property if it
is consistent with the ALUCP and the Airport Master Plan for Byron Airport. Policy 5-77, relatd to the ALUCP for Byron Airport, would
be updated to reflect the new compatibility zone designations (Zone B-1 would become Safety Zone 2) and the additional uses at the airport
that may be found compatible under the updated ALUCP. See Attachment E for the full text of the General Plan policy changes.
C. Airport Land Use Compatibility Plan Update: Every county in California that contains at least one public airport must prepare
an Airport Land Use Plan (also known as an Airport Land Use Compatibility Plan), per the State Aeronautics Act (Public Utilities Code
Section 21001 et seq.). The purpose of ALUCPs is to minimize the public’s exposure to excessive noise and safety hazards while providing
for the orderly expansion of airports. ALUCPs achieve this by identifying land use types and intensities that are compatible with four key
factors: safety, noise, airspace protection, and overflight. The Caltrans Division of Aeronautics,provides guidance on airport land use
planning in its California Airport Land Use Planning Handbook.
The ALUCP for Byron Airport was adopted in 2000, with minor modifications in 2006 and 2016. The current ALUCP reflects the original
1986 Airport Master Plan for the East Contra Costa County Airport (now Byron Airport). The Byron Airport Master Plan was updated in
2005. In addition, the Airport Layout Plan—required by the Federal Aviation Administration and a main component of the Airport Master
Plan—was updated in 2016. The standards used in the current ALUCP for Byron Airport are based on the 1993 edition of the Airport
Land Use Planning Handbook. Caltrans has updated this guidance document twice since that time, in 2002 and 2011. Thus, the
current ALUCP for Byron Airport does not reflect the latest planning and forecasts for the airport, and is based on dated compatibility
planning guidance. The 2016 Airport Layout Plan update also is not reflected in the current ALUCP for Byron Airport. The effect is an
ALUCP that does not allow the type of development envisioned in the Airport Master Plan, which would provide for the economic
development and fiscal self-sufficiency of Byron Airport.
The proposed ALUCP update for Byron Airport would revise the policies for Byron Airport, consistent with current Caltrans guidance and
the policy framework in effect at Buchanan Airport. The countywide policies in the ALUCP affecting Byron Airport would not change.
Key changes for Byron Airport policies are described below by category: safety, noise, airspace protection, and overflight.
1. Safety: Several important changes would be made to Byron Airport’s safety policies. These are driven primarily by applying the
latest Caltrans guidance to the airport. The current ALUCP for Byron Airport uses six “composite” zones known as zones A, B1,
B2, C1, C2, and D. These zones combine noise and safety criteria to determine compatible land uses. The proposed ALUCP update
would identify six safety zones (1 through 6) consistent with the current Airport Land Use Planning Handbook. By using
more carefully defined safety zones and by addressing noise compatibility separately, a greater range of development types would
be allowed. In addition, applying current Airport Land Use Planning Handbook standards for non-residential development
would increase the intensity of development allowed, and thereby support the County’s goals for economic development at the
airport.
2. Noise: The proposed ALUCP update for Byron Airport separates the noise criteria from the safety criteria when determining
compatible use. Noise compatibility is based on noise contours developed from forecasted aviation activity. The aviation forecasts
for the airport remain valid and would not be revised as part of the proposed ALUCP update. Therefore, the noise contours would
not change. The commercial and light industrial uses planned for the airport are not considered to be noise-sensitive uses.
Therefore, separating the noise criteria from the safety zones would increase the range and intensity of non-residential land uses.
3. Airspace Protection: Airspace protection policies regulate development that may interfere with the safe navigation of aircraft,
including physical structures or potential hazards such as dust, smoke, light/glare, and wildlife. Minor changes would be made to
airspace policies to reflect the 2016 Airport Layout Plan, including runway approach profiles. However, no significant changes
would be made to the policies, and there would be no effect on allowable land uses.
4. Overflight: Overflight policies do not regulate land use but identify the areas subject to noise from overflight (as compared to
noise from aircraft approaches and departures). The overflight area, along with airspace protection discussed above, helps to define
the airport influence area, in which home buyers must be notified of the presence of the airport. Overflight policies also identify
areas where aviation easements (dedicating airspace rights to the airport) should be acquired. The notification area would be slightly
larger in the proposed ALUCP update for Byron Airport to reflect the 2017 Airport Layout Plan, but there would be no change to
policies that would affect allowable land uses or future development.
The ALUCP update will be adopted by the Airport Land Use Commission subsequent to the Board of Supervisors certifying the Byron
Airport Development Program Final EIR. Adoption of the ALUCP update is anticipated for May or June 2022.
D. Development Plan Modification and Rezone: The airport property is currently zoned P-1. The P-1 zoning is intended to allow
diversification in the relationship of various uses, buildings, structures, lot sizes, and open space areas while ensuring compliance with the
General Plan and the intent of the County Code in requiring adequate standards necessary to satisfy the requirements of public health,
safety, and general welfare. Currently, the Byron Airport P-1 zoning only allows aviation-related uses, agriculture, and open space. The
amended Planned Unit District will identify four separate development areas: Aviation, Airport Related, Low-Intensity Use, and Habitat
Management (see Attachment G, Site Plan). These areas are further described below. The most important change would be to the
airport-related uses, which would allow non-residential development that is compatible with the ALUCP for Byron Airport. These uses
would include light industry, warehousing and logistics, commercial, and low-intensity office. In addition, the 11.7-acre parcel to be
acquired by the County would be rezoned from A-3 to P-1 in order to be included as part of the Byron Airport Development Program (see
Attachment F, Rezone Ordinance 2022-13). The Byron Airport Development Program also includes the following modifications to the P-1:
1. Aviation: A total of 23.5 acres is designated for aviation uses, located adjacent to the taxiways and runways. The aviation area is
adjacent to a developed 10.5-acre aircraft storage area and 9.7-acre aircraft parking area south of the main runway (Runway 12-30).
Proposed land uses in the aviation area include airport infrastructure (e.g., control tower, terminals), hangars, fixed-base operators,
businesses that directly support aviation and travel (e.g., aircraft service and fuel, rental car facilities, pilots lounge, meeting
facilities), and businesses that directly rely on aviation (e.g., agricultural aviation, aerial surveys and photography, air charter
businesses, air cargo, just-in-time delivery).
2. Non-Aviation (Airport-Related): Approximately 46.6 acres of Byron Airport is designated for non-aviation uses. This
includes 34.9 acres east of the main runway on the existing airport property, and 11.7 acres in the adjacent parcel. The 46.6 acres
would support commercial and light-industrial uses that are compatible with airport operations and would benefit from being
located at an airport, with access to Highway 4, Interstate 205, and Interstate 580. A variety of retail, service, warehouse and
distribution, light manufacturing, and low-density office uses would be allowed.
3. Low-Intensity Use: The areas adjacent to the ends of the primary runway and within the “no build” area adjacent to the
runway, approximately 31 acres, are designated as low-intensity use. No structures would be allowed within this area. Infrastructure
improvements may be allowed within this area.
4. Habitat Management Lands: Most of the project site, approximately 814 acres, is owned and managed by the County as
wildlife habitat, consistent with permit conditions imposed when the airport was constructed. The proposed project does not propose
any changes to habitat management lands.
5. Development Reserve: The 2005 Airport Master Plan identified a potential development area larger than the one currently
under consideration. The areas that have been removed from the aviation and non-aviation development area are identified as
“development reserve” in the proposed site plan. There are no land uses assigned to this category, it merely denotes an area that was
previously identified for potential development in the 2005 Airport Master Plan but is no longer considered part of the proposed
development program.
6. Development Scenario: Taking into account the land use areas described above and the proposed safety zones, DCD and
Airports Division staff developed a preferred development scenario. This scenario represents a reasonable distribution of compatible
land uses on the airport property and forms the basis of the impacts analysis in the EIR. The Development Scenario (Attachment H)
assigns a percentage of available acreage to the various uses (e.g., light industry), and estimates the potential building area as
increments of 1,000 square feet for those uses based on floor-to-area ratio. The number of people who may occupy the site at any
given time was then calculated using intensity factors from the Airport Land Use Planning Handbook and the County’s
General Plan. The percentages assigned to each non-aviation land use are estimated, but future land use demand would drive the
actual development scenario. As long as the overall building area is not exceeded, the impacts of development are not anticipated to
exceed the environmental analysis conducted as part of this project. Ongoing monitoring of land uses would ensure that incoming
land uses do not exceed the impacts analysis of this proposed program.
Environmental Review
DCD determined that the project required preparation of an environmental impact report (EIR) and, in accordance with CEQA, distributed a
Notice of Preparation (NOP) on September 21, 2017. The Draft EIR was released for public review on July 1, 2021, with the 60-day public
comment period ending on August 30, 2021. The Final EIR is attached for the Board of Supervisors' consideration.
The EIR identified potentially significant environmental impacts that would occur if the project was implemented and recommended
mitigation measures that would reduce most, but not all, of the potentially significant impacts to less-than-significant levels; some impacts
would remain significant and unavoidable. The attached CEQA Findings contain a statement of overriding considerations for the significant
and unavoidable impacts. All impacts and mitigation measures are spelled out in the attached Mitigation Monitoring and Reporting Program
(MMRP). All mitigation measures are also included in the attached conditions of approval.
A. Public Consultation & Comments on the EIR: DCD conferred with a number of federal, State, and local agencies and other
County departments prior to and during preparation of the EIR. Correspondence was received in response to the NOP, and written
comments were received from the following agencies and organizations during the public comment period for the Draft EIR:
1. Wilton Rancheria
2. California Department of Conservation – Geologic Energy Management Division
3. Delta Stewardship Council
4. Contra Costa Water District
All correspondence received during and after the 60-day public comment period for the Draft EIR and all responses to those comments are
included in the Final EIR.
B. Summary of Environmental Impacts: The Draft EIR identifies environmental impacts which would occur if the project was
implemented. Potentially significant and/or significant and unavoidable impacts were identified in the following Draft EIR topic areas:
1. Aesthetics: Discussed in detail in Draft EIR Section 3.1 (pages 3.1-1 to 3.1-53) and in the Final EIR. The DEIR identified
potentially significant impacts to views from surrounding roadways, including Armstrong Road and Byron Hot Springs Road.
However, all potentially significant impacts can be mitigated to less-than-significant levels.
2. Air Quality: Discussed in detail in Draft EIR Section 3.2 (pages 3.2-1 to 3.2-42) and in the Final EIR. Significant and
unavoidable impacts would occur during both construction and operation.
3. Biology: Discussed in detail in Draft EIR Section 3.3 (pages 3.3-1 to 3.1-38) and in the Final EIR. The DEIR identified
potentially significant impacts to a variety of special-status plant and animal species and their habitats. However, all potentially
significant impacts can be mitigated to less-than-significant levels.
4. Cultural Resources: Discussed in detail in Draft EIR Section 3.4 (pages 3.4-1 to 3.4-22) and in the Final EIR. The project site
is in the vicinity of Northern Valley Yokut territory, and the surrounding area is known to contain numerous archeological and
historical resources. The Draft EIR identified potentially significant impacts to cultural resources. However, all potentially
significant impacts can be mitigated to less-than-significant levels.
5. Geology, Soils and Minerals: Discussed in detail in Draft EIR Section 3.5 (pages 3.5-1 to 3.5-22) and in the Final EIR. The
Draft EIR identified potentially significant impacts related to expansive soil and liquefaction, as well as paleontological resources.
However, all potentially significant impacts can be mitigated to less-than-significant levels.
6. Greenhouse Gas Emissions: Discussed in detail in Draft EIR Section 3.6 (pages 3.6-1 to 3.6-40) and in the Final EIR.
Significant and unavoidable impacts would occur during operation and the implementation of individual development
projects under the scope of this development program.
7. Hazards and Hazardous Materials: Discussed in detail in Draft EIR Section 3.7 (pages 3.7-1 to 3.5-24) and in the Final
EIR. The Draft EIR identified potentially significant impacts related to hazardous material storage, use, and release sites. However,
all potentially significant impacts can be mitigated to less-than-significant levels.
8. Hydrology and Water Quality: Discussed in detail in Draft EIR Section 3.8 (pages 3.8-1 to 3.8-37) and in the Final EIR.
The Draft EIR identified potentially significant impacts related to land disturbance, creation of impervious surfaces, and/or release
or discharge of pollutants to groundwater or regional waters. However, all potentially significant impacts can be mitigated to
less-than-significant levels.
9. Noise: Discussed in detail in Draft EIR Section 3.10 (pages 3.10-1 to 3.10-28) and in the Final EIR. Significant and
unavoidable impacts would occur as a result of traffic generated by operation of individual development projects under the
scope of this development program.
10. Transportation and Traffic: Discussed in detail in Draft EIR Section 3.13 (pages 3.13-1 to 3.13-54) and in the Final EIR.
Significant and unavoidable impacts would occur as a result of traffic generated by operation of individual development
projects under the scope of this development program.
11. Utilities: Discussed in detail in Draft EIR Section 3.14 (pages 3.14-1 to 3.14-26) and in the Final EIR. The Draft EIR identified
potentially significant impacts related to exceeding the capacity of on-site utility systems, including water and wastewater.
However, all potentially significant impacts can be mitigated to less-than-significant levels.
County Planning Commission Hearing
The County Planning Commission (CPC) reviewed the Byron Airport Development Program at its March 9, 2022, hearing. The CPC took
public testimony and voted 6-0 to adopt a motion recommending that the Board of Supervisors approve the project as recommended by
staff. No significant issues were raised during the hearing.
Staff Discussion
A. Economic Development : Byron Airport currently operates at an annual net deficit. In order to develop economically beneficial
uses on the airport, development intensities must be increased to a level more consistent with current California Airport Land Use
Planning Handbook guidance. In addition, by de-coupling the noise and safety criteria in the ALUCP, a greater range of industrial and
commercial uses could be allowed at the airport. This approach would also create consistency with Buchanan Field, which does not use
composite compatibility zones.
The proposed project would help implement General Plan Goal 5-Q, to encourage the development and operation of two general purpose
public airports in the county, by providing for the economic development and financial self-sufficiency of Byron Airport. The General Plan
policies regarding the airport would be amended to clarify that compatible non-aviation uses would be allowed on airport property. General
Plan Policy 5-77 would be amended to specify that commercial or industrial development would be allowed on-airport if it is consistent
with the ALUCP and the Byron Airport Master Plan.
The P-1 zoning for Byron Airport would also be revised to identify the land use categories used in the ALUCP: aviation, non-aviation, low
intensity, and habitat management. Additional land uses that could be allowed within the aviation and non-aviation areas would be
identified, as discussed above and in Draft EIR Section 2.6, Proposed Land Uses and Zoning. The P-1 modification would specify that all
proposed land uses must be reviewed by County staff for consistency with the current ALUCP. The zoning would also implement the
ALUCP and General Plan standards for compatible land use, including height restrictions.
Not only would increasing the economic viability of Byron Airport help it operate in a financially beneficial way to the County, but it
would also help support the jobs/housing balance in East Contra Costa County. According to General Plan Table 2-4, the projected
jobs/hosing ratio for East County in 2020 was 0.45 jobs per resident. This low ratio results in a large population of East County residents
commuting out of the county for work, rather than commuting locally. This mass exodus from East County communities creates significant
traffic along local roads and highways, among other negative impacts to the environment and quality of life. Providing new, high quality
economic opportunities for residents in East County would help to improve in the jobs/housing ratio.
B. Transportation and Traffic: As discussed in detail in Draft EIR Section 3.13 (pages 3.13-1 to 3.13-54) and in the Final EIR,
significant and unavoidable impacts would occur as a result of traffic generated by operation of individual development projects under the
scope of this development program. The Vehicle Miles Traveled (VMT) per employee for the project is 21.2, compared to 14.0 for the
county and 14.9 for the Bay Area. A slight decrease in VMT per employee under the “with project” conditions compared to the “without
project” conditions indicates that the project would improve VMT efficiency in the region. However, the VMT “significance of impact”
threshold requires comparison of the project VMT with the regional average (i.e., Bay Area Average), and not a comparison of with project
and no project scenarios. The County threshold for Employment Projects (office, industrial, and institutional projects) is that the project
VMT should be 15% below Bay Area average commute VMT per employee (i.e., home-based work VMT per employee). The project’s
VMT per employee (21.2) is higher than the Bay Area VMT per employee (14.9). To meet the threshold of 15% below Bay Area Average
and have a less than significant VMT impact, the HBW VMT per employee for the project should be approximately 12.7, which would
require a 40% reduction. Therefore, the Draft EIR identified this as a potentially significant VMT impact. Transportation demand
management strategies and mitigation measures that can potentially achieve VMT reductions are provided in Draft EIR Section 3.13.5 and
the MMRP.
The project also has the potential to increase the volume of truck traffic on the roadway network to serve warehousing and light industrial
development. Although regional roadways, such as Byron Highway and State Route (SR-4), already safely handle significant volumes of
truck traffic, the rural roads providing access to Byron Airport may not support the increase in truck traffic. Existing traffic volumes can be
handled on these roads, but they may be inadequate for increased volumes of project-related traffic, including increased truck traffic. As
such, the Draft EIR identified this as a potentially significant impact. Therefore, the County or future developers would construct the street
improvements along Armstrong Road, Byron Hot Springs Road, and Holey Road described in Mitigation Measure (MM)-TRAF-9 to reduce
access impacts related to heavy truck traffic.
Finally, due to the potential for the proposed project to add traffic to Caltrans facilities within the traffic impact study area, the Caltrans
Mountain House Parkway/I-205 westbound ramps and Mountain House Parkway/I-205 eastbound ramps were analyzed for queuing
impacts. When comparing the Future Year 2040 scenario with the addition of the proposed project, queueing is forecasted to increase for all
vehicle movements during the AM peak hour at the Mountain House Parkway/I-205 westbound ramps; vehicle traffic would continue to
spill into the mainline lanes in Future Year 2040 “no Project” and “plus Project” conditions. No current funded or planned improvements
are identified at the I-205 westbound ramps with Mountain House Parkway. The SR-239 Feasibility Study Final Report identifies potential
alignments for the proposed SR-239 corridor between SR-4 to the north and I-580 and/or I-205 to the south, which would reduce traffic
volumes on I-580, Vasco Road, and Byron Highway (SR-239 is a proposed roadway connecting Vasco Road in Contra Costa County to the
I-580/I-205 interchange in Alameda County or I-205 in San Joaquin County). As such, shifts in regional traffic patterns could also reduce
congestion and queuing at the Mountain House Parkway/I-205 westbound ramps. However, as the SR-239 Feasibility Study does not
identify specific improvements, nor are specific improvements planned or funded in the area, hazards related to queuing at this off-ramp
would remain significant and unavoidable.
C. Utilities: The project site is not connected to public water services; instead, the airport relies on existing on-site water wells and a
4,000-gallon on-site water tank for its domestic, non-potable water. Bottled water is used for drinking water. Development of the proposed
project would exceed the capacity of the existing system, resulting in a potentially significant impact. According to the Water Supply
Assessment completed for the project, at the programmatic level of analysis, sufficient water supplies are available to serve its water
demand under normal and dry conditions, including existing and planned land uses, over the 20-year projection period (Draft EIR
Appendix I). This would be accomplished through the use of one or more of the proposed options, including on-site expansion of wells for
extraction and treatment of additional groundwater, importation of treated water from Discovery Bay Community Services District (CSD),
or importation and on-site treatment of additional water from Byron-Bethany Irrigation District (BBID). However, as development under
the proposed project proceeds, each of the potential supplies considered would require additional feasibility analysis to determine the actual
potential for project implementation, and would require appropriate agreements (e.g., will-serve letter) from the off-site suppliers before any
development requiring potable water could be permitted. This process is incorporated into MM-UTIL-1. Connection to either Discovery
Bay CSD or BBID may also conflict with the County’s Urban Limit Line policy, so on-site expansion of groundwater systems would be
the preferred method.
The project site is not connected to public sewer services; instead, the airport relies on an existing on-site septic system and leach field for
its sanitary service. The 2013 Byron Airport Infrastructure Study considered two potential wastewater generation rates for bulk
warehousing and industrial development: the Central Contra Costa Sanitary District’s Collection System Master Plan rate of 1,000 gallon
per day (gpd) per gross acre, and the City of Oakland rate of 25 gpd per 1,000 square feet of building square footage. The Infrastructure
Study used the Oakland rate of 25 gpd per 1,000 square feet, resulting in an estimated 96,000 gpd build-out demand. The development
assumptions in the Infrastructure Study are greater than for the proposed project (146.9 acres and 3,840,000 square feet of building space,
compared to 70.9 acres and 941,000 square feet of building space for the proposed project). Applying the Oakland rate to the proposed
project would result in an estimated wastewater flow of 23,525 gpd. However, the Town of Discovery Bay, which contains the nearest
wastewater treatment plant, uses a wastewater generation rate of 2,000 gpd per acre of industrial development and 1,600 gpd per acre of
commercial development. Using these flow rates, wastewater flow would be 89,920 gpd for non-aviation uses.
MM-UTIL-2 requires implementation of a wastewater system, per the recommendations of the Byron Airport Infrastructure Study (Mead &
Hunt 2013), which studied several options for expansion of the on-site sewer system. The options include requiring each new use or
development to provide for its own wastewater disposal, in effect distributing wastewater treatment to smaller leach fields throughout the
site, or development of centralized treatment though use of an on-site package wastewater treatment plant and establishment of collection
pipelines. For an on-site treatment plant, effluent disposal may be accomplished through landscape irrigation if the effluent is treated to a
level to meet Title 22 CCR standards. A third option is connection to an existing sewer system: either the Discovery Bay CSD or the Byron
Sanitary District. Connection to Discovery Bay would involve off-site construction of a force main and likely modifications to the existing
sewage lift station (or a new lift station). Connection to Byron Sanitary District would likely require an expansion of Byron Sanitary
District’s wastewater treatment facility. Connection to either Discovery Bay or Byron Sanitary District may also conflict with the County’s
Urban Limit Line policy, so on-site expansion of septic systems and leach fields would be the ideal method.
The proposed project’s requirements would exceed existing water and wastewater infrastructure, which would have a potentially significant
impact without mitigation. The construction impacts associated with expansion of required infrastructure are addressed in the Draft and
Final EIR and do not represent new significant impacts.
Conclusion
The record demonstrates that the Byron Airport Development Program warrants approval. The project would not threaten the health, safety,
and general welfare of the public; it would improve the economic viability of Byron Airport; it would expand economic opportunities in
East County; and most potentially significant impacts can be mitigated to less-than-significant levels. Staff therefore recommends that the
Board of Supervisors adopt a motion to approve the Byron Airport Development Program, as outlined at the beginning of this report.
CONSEQUENCE OF NEGATIVE ACTION:
If the Byron Airport Developmet Program is not approved, then the airport will remain in its current state. The General Plan Transportation
Element policies will not be amended, the 11.7-acre parcel will retain its AL designation, the P-1 zoning and Development Plan will remain
unchanged, and the ALUCP will not be updated because that update relies on Board certification of the Final EIR. The project's overarching
goal, economic self-sufficiency for Byron Airport, will not be realized.

THE BOARD OF SUPERVISORS OF CONTRA COSTA COUNTY, CALIFORNIA
and for Special Districts, Agencies and Authorities Governed by the Board
Adopted this Resolution on 04/26/2022 by the following vote:
AYE:
NO:
ABSENT:
ABSTAIN:
RECUSE:
Resolution No. 2022/128
IN THE MATTER of approving a General Plan Amendment for the Byron Airport Development Program.
WHEREAS, the Contra Costa County Board of Supervisors held a public hearing on April 26, 2022, to consider the Byron
Airport Development Program, proposed for the unincorporated Byron area. The Project includes certification of an
environmental impact report and adoption of the mitigation monitoring and reporting program prepared for the Project, adoption
of a General Plan Amendment (County File #GP12-0003) and rezoning ordinance (County File #21-3262), and approval of a
development plan modification (County File #DP14-3008).
WHEREAS, the General Plan Amendment for the Project amends the Land Use Element Map to redesignate approximately 11.7
acres of land from Agricultural Lands (AL) to Public and Semi-Public (PS).
WHEREAS, the General Plan Amendment for the Project amends the Transportation and Circulation Element of the 2005-2020
Contra Costa County General Plan to revise policies 5-66 and 5-77 to expand the range of land uses and activities allowed at
Byron Airport and modify the Airport Land Use Compatibility Plan (ALUCP) compatibility zone designations.
WHEREAS, a resolution is required under Government Code Section 65356 to amend a general plan.
NOW, THEREFORE, the Contra Costa County Board of Supervisors resolves as follows:
A. The Board of Supervisors makes the following General Plan Amendment findings:
1. No change to the County's Urban Limit Line (ULL) is proposed, and no extension of urban services outside the ULL is
proposed. The portion of the subject property where development may occur is fully inside the ULL and therefore may be
developed with “urban” or “non-urban” uses, as defined in the 2005-2020 Contra Costa County General Plan. The Public
and Semi-Public (PS) land use designation for Byron Airport is non-urban. All proposed land uses, both aviation-related
and non-aviation-related, will be located on land designated PS and within the ULL.
2. Adoption of the proposed General Plan Amendment (GPA) will not cause a violation of the 65/35 Land Preservation
Standard (the “65/35 Standard”), originally approved by County voters through adoption of Measure C-1990 and
reaffirmed through adoption of Measure L-2006. Under the 65/35 Standard, no more than 35 percent of the land in the
County may be developed with urban uses and at least 65 percent of the land must be preserved for non-urban uses such as
agriculture, open space, parks, wetlands, and public facilities. The existing land use designations for the subject site, Public
and Semi-Public (PS) and Agricultural Lands (AL), are non-urban land use designations. Changing the land use
designation for 11.7 acres from AL to PS does not change the percentage of land devoted to urban and non-urban uses.
3. The project complies with the objectives and requirements of Measure J-2004, the Contra Costa Transit Authority
(CCTA) Growth Management Program (GMP), and related CCTA resolutions. The CCTA GMP Implementation Guide
(2021) sets forth procedures for local agency consultation and evaluation of impacts of proposed General Plan
Amendments. The Byron Airport Development Program EIR was evaluated according to the CCTA GMP GPA Review
Process and Technical Procedures for evaluating transportation impacts. Therefore, the project complies with the objectives
and requirements of Measure J-2004, the Contra Costa Growth Management Program, and related CCTA resolutions.
4. The General Plan comprises an integrated, internally consistent, and compatible statement of policies governing
development in the unincorporated areas. The GPA involves revising Transportation and Circulation Element policies 5-66
and 5-77 to allow additional uses at Byron Airport and integrate updates to the Airport Land Use Compatibility Plan,
respectively, and redesignating 11.7 acres from AL to PS. The two policies are very specific to Byron Airport and do not
affect County policy unrelated to that facility. Redesignating 11.7 acres for acquisition by the County is consistent with the
General Plan's policies for the Southeast County/Byron area and compatible with surrounding land use designations.
Therefore, adoption of the proposed GPA will not cause the General Plan to become internally inconsistent.
5. Pursuant to Government Code Section 65358(a), the General Plan may be amended if such amendment is deemed to be
“in the public interest.” The Project helps the County achieve General Plan Goal 5-Q, to encourage development and
operation of two general purpose public airports, by supporting Byron Airport's fiscal self-sufficiency. The Project
achieves this by allowing additional aviation and non-aviation development on airport property, which in turn allows for
revenue increases from ground leases, user fees, and other revenue streams. The Project also serves to improve the severe
jobs/housing imbalance in East County by adding employment opportunities at the airport.
6. Pursuant to Government Code Section 65358(b), no mandatory element of the General Plan may be amended more than
four times per calendar year. The proposed GPA affects the Land Use and Transportation and Circulation elements, both
mandatory elements, and is part of the first consolidated General Plan Amendment for 2022.
B. The Board of Supervisors hereby ADOPTS the General Plan Amendment (County File #GP12-0003) to redesignate an
11.7-acre portion of the subject property from Agricultural Lands (AL) to Public and Semi-Public (PS), and revise Transportation
and Circulation Element policies 5-66 and 5-77, and ADOPTS said General Plan Amendment as part of the first consolidated
General Plan Amendment to the Land Use and Transportation and Circulation elements for calendar year 2022, as permitted by
State Planning Law.

CALIFORNIA ENVIRONMENTAL QUALITY ACT FINDINGS OF FACT AND
STATEMENT OF OVERRIDING CONSIDERATIONS FOR THE
BYRON AIRPORT DEVLOPMENT PROGRAM (PROJECT)
I. Introduction
No public agency shall approve or carry out a project for which an environmental impact report
has been certified which identifies one or more significant effects on the environment that would
occur if the project is approved or carried unless one or more written findings is made for each of
those significant effects. Public Resources Code 21081 and Section 15091 of the CEQA
Guidelines require that the lead agency prepare written findings for identified significant impacts,
accompanied by a brief explanation for the rationale for each finding. Contra Costa County
(County) is the lead agency responsible for preparation of the EIR in compliance with CEQA and
the CEQA Guidelines.
Section 15091 of the CEQA Guidelines states, in part, that:
a) No public agency shall approve or carry out a project for which an EIR has been certified
which identifies one or more significant environmental effects of the project unless the
public agency makes one or more written findings for each of those significant effects,
accompanied by a brief explanation of the rationale for each finding. The possible findings
are:
1) Changes or alterations have been required in, or incorporated into, the project which
avoid or substantially lessen the significant environmental effect as identified in the
Final EIR.
2) Such changes or alterations are within the responsibility and jurisdiction of another
public agency and not the agency making the finding. Such changes have been adopted
by such other agency or can and should be adopted by such other agency.
3) Specific economic, legal, social, technological, or other considerations, including
provision of employment opportunities for highly trained workers, make infeasible the
mitigation measures or project alternatives identified in the Final EIR.
In accordance with Public Resource Code 21081 and Section 15093 of the CEQA Guidelines,
whenever significant impacts cannot be mitigated to below a level of significance, the decision-
making agency is required to balance, as applicable, the benefits of the proposed project against
its unavoidable environmental risks when determining whether to approve the project. If the
benefits of a proposed project outweigh the unavoidable adverse environmental effects, the adverse
effects may be considered "acceptable." In that case, the decision-making agency may prepare and
adopt a Statement of Overriding Considerations, pursuant to the CEQA Guidelines.
2
The County proposed to approve the Byron Airport Development Program (project). The County
has certified an Environmental Impact Report (EIR) for the project which identifies significant
effects on the environment (SCH# 2017092059). These findings, as well as the accompanying
statement of overriding considerations in Section VIII, infra, have been prepared in accordance
with the California Environmental Quality Act (CEQA) (Public Resources Code, Section 21000
et seq.) and its implementing guidelines, the CEQA Guidelines (California Code of Regulations
Title 14, Section 15000 et seq.)
The Final EIR for the proposed project identified potentially significant effects that could result
from implementation. However, the County Board of Supervisors (Board) finds that the inclusion
of certain mitigation measures as part of the project approval would reduce most, but not all, of
those effects to less than significant levels. Those impacts that are not reduced to less-than-
significant levels are identified and overridden due to specific project benefits in a Statement of
Overriding Considerations.
In accordance with CEQA and the CEQA Guidelines, the Board adopts these Findings as part of
its certification of the Final EIR and approval of the proposed project. Pursuant to Section
21082.1(c)(3) of the Public Resources Code, the Board also finds that the Final EIR reflects the
Board's independent judgment as the lead agency for the project. As required by CEQA, the Board,
in adopting these Findings, also adopts a Mitigation Monitoring and Reporting Program (MMRP)
for the proposed project. The Board finds that the MMRP, which is incorporated by reference and
made a part of these Findings, meets the requirements of Section 21081.6 of the Public Resources
Code by providing for the implementation and monitoring of measures intended to mitigate
potentially significant effects of the project.
II. Project Overview
The County intends to amend its Airport Land Use Compatibility Plan (ALUCP), General Plan,
and Planned Unit District zoning to broaden the range of uses allowed on airport property. These
amendments will include a variety of aviation uses (terminal, hangers, fixed-base operators,
aircraft sales, aviation supporting businesses, etc.) and airport-compatible uses (light industry,
warehousing and distribution, general commercial and retail, offices, etc.). Approximately 941,000
square feet of new development may be constructed under the project. The project is further
described in Chapter 2, Project Description, of the EIR (incorporated here by reference).
III. Project Objectives
CEQA requires the statement of a project’s objectives to be clearly written so as to define the
underlying purpose of a project in order to permit development of a reasonable range of
alternatives and aid the lead agency in making findings when considering a project for approval.
The objectives and goals of the proposed project are as follows:
3
• Develop airport facilities to support the types of development envisioned in the Airport
Master Plan and subsequent airport planning efforts.
• Achieve economic self-sufficiency of the airport through the development of airport-
related land uses.
• Protect current and future airport operations from incompatible land uses.
• Provide a streamlined planning framework for future development consistent with the
General Plan and the ALUCP.
IV. Environmental Review Process
Notice of Preparation
In accordance with CEQA Guidelines Section 15082, a Notice of Preparation (NOP) was
circulated for public and agency review from September 20, 2017, through October 20, 2017
(included as Appendix A of the EIR). The purpose of the NOP was to provide notification that an
EIR for the proposed project was being prepared and to solicit guidance on the scope and content
of the document.
Pursuant to CEQA Guidelines Section 15082, the lead agency held a public scoping meeting on
October 16, 2017. Responsible agencies and members of the public were invited to attend and
provide input on the scope of the EIR. Comments from agencies and the public in response to the
NOP are provided in Appendix B of the EIR. General concerns and issues raised in response to
the NOP are summarized in the Executive Summary of the EIR and are addressed in the technical
sections in Chapter 3 of the EIR.
Draft EIR and Public Review
The Draft EIR was circulated for public review and comment for a period of 60 days, between July
1, 2021 and August 30, 2021. All comment letters received in response to the Draft EIR were
reviewed and included in the Final EIR, and responses to these comments relevant to CEQA were
addressed in the Final EIR in compliance with the CEQA Guidelines (Sections 15088, 15132).
Final EIR
Upon completion of the Draft EIR public review period, a Final EIR was prepared that includes
written comments on the Draft EIR received during the public review period and the County’s
responses to those comments. The intent of the Final EIR is to provide a forum to address
comments pertaining to the information and analysis contained within the Draft EIR, and to
provide an opportunity for clarifications, corrections, or revisions to the Draft EIR as needed and
as appropriate. The Final EIR also includes the MMRP prepared in accordance with Section
21081.6 of the Public Resource Code. The Final EIR includes revisions to the Draft EIR made in
4
response to agency or public comments. The Draft EIR and Final EIR together comprise the EIR
for the proposed project.
V. Record of Proceedings
The record of proceedings, including the Final EIR and supporting documents is available during
normal business hours (Monday through Friday, 8 a.m. to 4 p.m.) at:
Contra Costa County
Department of Conservation and Development
30 Muir Road
Martinez, California 94533
VI. Significant Effects and Mitigation Measures
The EIR identifies significant environmental effects (or impacts) resulting from implementation
of the project.
The County’s findings with respect to the project’s significant effects and mitigation measures are
set forth below for each significant impact. The following statement of findings does not attempt
to describe the full analysis of each environmental impact contained in the EIR. Instead, it provides
a summary description of each impact, describes the applicable mitigation measures identified in
the EIR and adopted by the County, and states the County’s findings on the significance of each
impact after imposition of the adopted mitigation measures, accompanied by a brief explanation.
Full explanations of these environmental findings and conclusions can be found in the EIR. These
findings hereby incorporate by reference the discussion and analysis in those documents
supporting the EIR’s determinations regarding mitigation measures and the project’s impacts and
mitigation measures designed to address those impacts. In making these findings, the Board
ratifies, adopts, and incorporates into these findings the analysis and explanation in the EIR and
ratifies, adopts, and incorporates in these findings the determinations and conclusions of the EIR
relating to environmental impacts and mitigation measures, except to the extent any such
determinations and conclusions are specifically and expressly modified by these findings.
Significant Impacts That Can Be Mitigated to a Less-Than-Significant Level
Pursuant to Section 21081(a) of the Public Resources Code and Section 15091(a)(1) of the CEQA
Guidelines, the County Board of Supervisors finds that, for each of the following significant effects
identified in the Final EIR, changes or alterations have been required in, or incorporated into, the
proposed project which mitigate or avoid the identified significant effects on the environment to
less than significant levels. These findings are explained below and are supported by substantial
evidence in the record of proceedings.
5
Aesthetics
Visual character or quality of public views of the site and its surroundings (Impact 3.1-2).
Depending on the massing of these buildings, the impact to public views (public road adjacent to
the airport) would be potentially significant.
Mitigation Measure
MM-AES-1: Non-aviation development shall be subject to the following design requirements:
• Long facades should be designed with building articulation and landscaping to
break them up into smaller visual elements, avoiding public views of
uninterrupted blank walls.
• For industrial and warehouse buildings, bright reflective colors and materials
shall not be allowed. Paint colors should be earth tones. Natural finishes such
as brick or stone facades may also be incorporated into the design.
• Project lighting shall comply with the policies of the Airport Land Use
Compatibility Plan.
• Loading areas should be located and designed to minimize direct exposure to
public views.
• Structures and parking lots located on the eastern edge of the airport property
shall incorporate landscaping to screen public views. The type, quantity and
placement of plant material should be selected for its compatibility with airport
uses (tree heights, plants that are not wildlife attractants), as well as structure,
texture, color and compatibility with the building design and materials.
The design of non-aviation development shall be reviewed by both Department of
Conservation and Development and Airports Division staff prior to issuance of
building permits for conformance with these standards. Aviation uses shall be
reviewed by Airports Division staff.
Finding
The County Board of Supervisors finds that the above mitigation measure is feasible, will reduce
the potential aesthetic impact (Impact 3.1-2) of the project to a less-than-significant level, and is
adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors finds,
that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines Section
15091(a)(1), changes or alterations have been required in, or incorporated into, the project, which
avoid or substantially lessen the significant environmental effect as identified in the Final EIR.
6
Rationale
The proposed mitigation measure includes design requirements and design review procedures to
ensure that future structures would be visually compatible and properly screened from views from
public roads. With implementation of the mitigation measure, the potential impact to aesthetics
would be reduced to less than significant.
Air Quality
Expose sensitive receptors to substantial pollutant concentrations (Impact 3.2-4). Operation of
the project could result in exceedances of the Bay Area Air Quality Management District
(BAAQMD) significance thresholds for NO x and PM 10 and the project would potentially result in
health effects associated with those pollutants; the potential health effects associated with criteria
air pollutants are potentially significant.
Mitigation Measures
MM-AQ-3: For non-aviation facilities with construction proposed within 1,000 feet of off-site
residential receptors, a construction health risk assessment shall be prepared to
assess exposure of existing sensitive receptors to toxic air contaminants (TACs)
during project construction. If the health risk assessment determines that cancer and
non-cancer impacts would be less than significant, no additional measures are
needed. Alternatively, the results of the health risk assessment may necessitate
implementation of TAC exposure reduction strategies in order to reduce potential
risk to less-than-significant levels, which could include, but are not limited to, the
following:
• Portable equipment used during construction shall be powered by electricity
from the grid instead of diesel-powered generators, to the maximum amount
feasible.
• Equip heavy-duty diesel-powered construction equipment with Tier 4 Interim
or better diesel engines, except where Tier 4 Interim or better engines are not
available for specific construction equipment. Contra Costa County shall verify
and approve all pieces within the construction fleet that would not meet Tier 4
Interim standards. At a minimum, Tier 3 engines will be required if Tier 4
engines are not available.
• All conditions of approval/mitigations shall be placed on construction drawings
and part of any construction contract. Physical copies of the plans shall be
available at the on-site job trailer.
7
MM-AQ-4: For non-aviation uses, a health risk assessment of long-term operations shall be
prepared if the proposed facility is within 1,000 feet of off-site residential receptors
and would result in any of the following:
• Accommodate more than 100 trucks per day, or
• Accommodate more than 40 trucks with operating transport refrigeration units
(TRUs) per day, or
• Where TRU operations exceed 300 hours per week.
Results of the health risk assessment may necessitate implementation of TAC
exposure reduction strategies in order to reduce potential risk to less-than-
significant levels, which could include, but are not limited to, the following:
• Idling of diesel equipment of any type shall be strictly prohibited at the
premises. The property owner/tenant/lessee shall inform all business partners,
visitors, etc., of the Zero-Idling Rule in effect for the subject property and area
streets. Highly visible signs prohibiting idling shall be posted at each entrance
and exits. Violators of this zero-idling rule are subject to fines and or criminal
charges.
• Within 90 days of occupying the space, the facility operator shall submit to the
Airports Division and the Department of Conservation and Development
(DCD) the first of an annual inventory of all equipment that generates criteria
pollutant, TACs, and GHG emissions operated at the subject location
throughout the life of the project up to year 2035. The equipment inventory
shall include the year, make, and model of the equipment that was used in the
previous year, including annual hours of operation for each piece of equipment,
including but not limited to heavy-duty drayage and non-drayage trucks, yard
equipment, bulk material handling equipment (forklifts, etc.), and any other
type of material handling equipment. The purpose of the inventory is to track
emissions/equipment and to assist in technology reviews.
• The facility operator shall purchase/lease or otherwise acquire zero-emission
vehicles/equipment (including: light/heavy duty trucks, drayage equipment,
forklifts, and generators) when commercially available as the attrition of
gasoline/diesel equipment occurs. The property owner/tenant/lessee is
encouraged to utilize any and all funding opportunities offered by CARB and
other available programs. The availability of zero-emission equipment shall be
determined in a joint effort between the Airports Division and the facility
operator as part of an annual technology review.
• The facility operator shall adhere to the findings of the annual technologies
review for reducing air emissions as part of the County Climate Action Plan
and long-range sustainability goals, which encourage property owners and
8
tenants to use cleaner technologies over time as they become available. A
priority goal of the review will be the replacement of older equipment in
operation at the subject site that generates the highest levels of criteria pollutant,
TAC, and GHG emissions. The equipment to be replaced will be determined
based on the level of emissions and cost-effectiveness of the emissions
reduction (e.g., biggest reduction per dollar), and identify implementation
mechanisms including, but not limited to, tenant-based improvements, grant
programs, or a combination thereof, based on regulatory requirements and the
feasibility analysis performed by the Airports Division. The Carl Moyer
Program, or similar cost-effectiveness criteria, shall be used to assess the
economic feasibility (e.g., cost effectiveness) of the identified new
technologies. Zero-emission equipment employed pursuant to this mitigation
may be replaced by other technologies or other types of equipment as long as
the replacement equipment achieves the same or greater criteria pollutant, TAC,
and GHG emission reductions as compared to the equipment identified as part
of the technology review.
• Every California based TRU and electronic-TRU (E-TRU) operational at the
site must be registered with the Air Resource Board Equipment Registration
and shall be labeled with a CARB Identification Number. Business operations
handling TRUs shall install charging infrastructure and encourage E-TRUs on
site, and require those non-E-TRUs to plug in while stationary at the facility.
• Prior to occupancy the facility operator shall demonstrate compliance with all
newly adopted Ordinances/Statutes/Plans and requirements passed by all
responsible agencies in relation to traffic, diesel emissions and air quality
improvement measures.
Finding
The County Board of Supervisors finds that the above mitigation measures are feasible, will reduce
the potential air quality impact (Impact 3.2-4) of the project to a less-than-significant level, and is
adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors finds,
that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines Section
15091(a)(1), changes or alterations have been required in, or incorporated into, the project, which
avoid or substantially lessen the significant environmental effect as identified in the Final EIR.
Rationale
Emissions of toxic air contaminants (TACs) may adversely affect sensitive residential receptors.
The impact is based on the type and amount of emissions, and the proximity and exposure of the
sensitive receptors. The proposed mitigation measures would assess the construction and operation
of future developments under the project, and require emission reductions to a level that is
9
considered a less-than-significant health risk by the BAAQMD and the State of California. As
described in the mitigation measures, feasible methods are available to reduce TAC exposure.
With implementation of the mitigation measures, the potential impact would be reduced to less
than significant.
Biological Resources
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. (Impact 3.3-1). Three special-status wildlife species were detected during the surveys
conducted for the project site, as discussed in Section 3.3.1.3. These species include loggerhead
shrike, golden eagle, and tricolored blackbird. Several other special-status species have the
potential to utilize the project site for nesting, foraging, cover and/or local migration routes.
Although the study area has few mature trees, the project site and adjacent lands have potential
nesting habitat for Swainson’s hawk and several common raptor species found in California, such
as northern harrier and red-tailed hawk (Buteo jamaicensis), and common passerine species such
as western meadowlark. Increased noise, light, and vibration associated with construction activities
could negatively affect nesting success if such activities occur during the nesting season. Annual
grassland within the study area provides suitable nesting habitat for Burrowing owl. Ground-
disturbing activities in grassland habitat has potential to cause direct impacts to suitable nesting
and upland refuge habitat for burrowing owl, California red-legged frog, and California tiger
salamander. While no special status plants were identified within the project area, there are nine
species with potential to occur in the project area.
Mitigation Measures
MM-BIO-1: a. Swainson’s Hawk Pre-Construction Survey, Avoidance, Minimization and
Construction Monitoring. Prior to any ground disturbance related to covered
activities that occurs during the nesting season (March 15–September 15), a
qualified biologist shall conduct a preconstruction survey no more than 1 month
prior to construction to establish whether Swainson’s hawk nests within 1,000 feet
of the project site are occupied. If potentially occupied nests within 1,000 feet are
off the project site, then their occupancy shall be determined by observation from
public roads or by observations of Swainson’s hawk activity (e.g., foraging) near
the project site. If nests are occupied, minimization measures and construction
monitoring are required (see below).
During the nesting season (March 15–September 15), covered activities within
1,000 feet of occupied nests or nests under construction shall be prohibited to
prevent nest abandonment. If site-specific conditions or the nature of the covered
activity (e.g., steep topography, dense vegetation, limited activities) indicate that a
10
smaller buffer could be used, the East Contra Costa County Habitat Conservancy
shall coordinate with the California Department of Fish and Wildlife (CDFW)/U.S.
Fish and Wildlife Service (USFWS) to determine the appropriate buffer size.
If young fledge prior to September 15, covered activities can proceed normally. If
the active nest site is shielded from view and noise from the project site by other
development, topography, or other features, the project proponent can apply to the
East Contra Costa County Habitat Conservancy for a waiver of this avoidance
measure. Any waiver must also be approved by USFWS and CDFW. While the
nest is occupied, activities outside the buffer can take place.
All active nest trees shall be preserved on site, if feasible. Nest trees, including non-
native trees, lost to covered activities shall be mitigated by planting 15 saplings for
every tree lost with the objective of having at least 5 mature trees established for
every tree lost according. Preference shall be to provide on-site mitigation if
feasible. Planting of replacement trees must be reviewed by the Airports Division
for compatibility with airport operations. The project proponent shall either pay the
East Contra Costa County Habitat Conservancy (Habitat Conservancy) an
additional fee to purchase, plant, maintain, and monitor 15 saplings on the East
Contra Costa County Habitat Conservation Plan (HCP)/Natural Community
Conservation Plan (NCCP) Preserve System for every tree lost, or the project
proponent shall plant, maintain, and monitor 15 saplings for every tree lost at a site
to be approved by the Habitat Conservancy and per the requirements of the
HCP/NCCP.
b. Migratory Bird Treaty Act Nesting Bird Avoidance. As part of the pre-
construction survey for Swainson’s Hawk, the qualified biologist approved by
Contra Costa County shall also survey for native nesting birds protected by the
Migratory Bird Treaty Act. If any active nests are observed during surveys, a
suitable avoidance buffer from the nests shall be determined and flagged by the
qualified biologist based on species, location and planned construction activity.
Consultation with CDFW may be required to determine appropriate buffer
distances. These nests shall be avoided until the chicks have fledged and the nests
are no longer active, as determined by the qualified biologist. Any habitat (i.e., trees
and brush) would be removed outside of the breeding bird season.
MM-BIO-2: Western Burrowing Owl Pre-Construction Survey, Avoidance, Minimization,
and Construction Monitoring. In accordance with Conditions on Covered
Activities described in the East Contra Costa County Habitat Conservation
Plan/Natural Community Conservation Plan, prior to any ground disturbance
related to covered activities, a U.S. Fish and Wildlife Service (USFWS)/California
11
Department of Fish and Wildlife (CDFW)-approved biologist shall conduct a
preconstruction survey in grassland areas identified as having potential burrowing
owl habitat. The surveys shall establish the presence or absence of western
burrowing owl and/or habitat features and evaluate use by owls in accordance with
CDFW survey guidelines (CDFG 1995).
On the parcel where the activity is proposed, the biologist shall survey the proposed
disturbance footprint and a 500-foot radius from the perimeter of the proposed
footprint to identify burrows and owls. Adjacent parcels under different land
ownership shall not be surveyed. Surveys should take place near sunrise or sunset
in accordance with CDFW guidelines. All burrows or burrowing owls shall be
identified and mapped. Surveys shall take place no more than 30 days prior to
construction. During the breeding season (February 1–August 31), surveys shall
document whether burrowing owls are nesting in or directly adjacent to disturbance
areas. During the nonbreeding season (September 1–January 31), surveys shall
document whether burrowing owls are using habitat in or directly adjacent to any
disturbance area. Survey results shall be valid only for the season (breeding or
nonbreeding) during which the survey is conducted.
This measure incorporates avoidance and minimization guidelines from CDFW’s
Staff Report on Burrowing Owl Mitigation (California Department of Fish and
Game 1995).
If burrowing owls are found during the breeding season (February 1–August 31),
the project proponent shall avoid all nest sites that could be disturbed by project
construction during the remainder of the breeding season or while the nest is
occupied by adults or young. Avoidance shall include establishment of a non-
disturbance buffer zone (described below). Construction may occur during the
breeding season if a qualified biologist monitors the nest and determines that the
birds have not begun egg-laying and incubation or that the juveniles from the
occupied burrows have fledged. During the nonbreeding season (September 1–
January 31), the project proponent should avoid the owls and the burrows they are
using, if possible. Avoidance shall include the establishment of a buffer zone
(described below).
During the breeding season, buffer zones of at least 250 feet in which no
construction activities can occur shall be established around each occupied burrow
(nest site). Buffer zones of 160 feet shall be established around each burrow being
used during the nonbreeding season. The buffers shall be delineated by highly
visible, temporary construction fencing.
12
If occupied burrows for burrowing owls are not avoided, passive relocation shall
be implemented. Owls should be excluded from burrows in the immediate impact
zone and within a 160-foot buffer zone by installing one-way doors in burrow
entrances. These doors should be in place for 48 hours prior to excavation. The
project area should be monitored daily for 1 week to confirm that the owl has
abandoned the burrow. Whenever possible, burrows should be excavated using
hand tools and refilled to prevent reoccupation (CDFG 1995). Plastic tubing or a
similar structure should be inserted in the tunnels during excavation to maintain an
escape route for any owls inside the burrow.
MM-BIO-3: California Red-Legged Frog Avoidance. Written notification to U.S. Fish and
Wildlife Service (USFWS), California Department of Fish and Wildlife (CDFW),
and the East Contra Costa County Habitat Conservancy, including, photos and
habitat assessment, is required prior to disturbance of any suitable breeding habitat.
The project proponent shall also notify these parties of the approximate date of
removal of the breeding habitat at least 30 days prior to this removal to allow
USFWS or CDFW staff to translocate individuals, if requested. USFWS or CDFW
must notify the project proponent of their intent to translocate California red-legged
frog within 14 days of receiving notice from the project proponent. The project
proponent must allow USFWS or CDFW access to the site prior to construction if
they request it.
There are no restrictions under the East Contra Costa County Habitat Conservation
Plan/Natural Community Conservation Plan on the nature of the disturbance or the
date of the disturbance unless CDFW or USFWS notify the project proponent of
their intent to translocate individuals within the required time period. In this case,
the project proponent must coordinate the timing of disturbance of the breeding
habitat to allow USFWS or CDFW to translocate the individuals.
USFWS and CDFW shall be allowed 45 days to translocate individuals from the
date the first written notification was submitted by the project proponent (or a
longer period agreed to by the project proponent, USFWS, and CDFW).
MM-BIO-4: California Tiger Salamander Minimization. Written notification to USFWS,
CDFW, and the Implementing Entity, including photos and breeding habitat
assessment, is required prior to disturbance of any suitable breeding habitat. The
project proponent will also notify these parties of the approximate date of removal
of the breeding habitat at least 30 days prior to this removal to allow USFWS or
CDFW staff to translocate individuals, if requested. USFWS or CDFW must notify
the project proponent of their intent to translocate California tiger salamanders
13
within 14 days of receiving notice from the project proponent. The applicant must
allow USFWS or CDFW access to the site prior to construction if they request it.
There are no restrictions under the East Contra Costa County Habitat Conservation
Plan/Natural Community Conservation Plan on the nature of the disturbance or the
date of the disturbance unless CDFW or USFWS notify the project proponent of
their intent to translocate individual California tiger salamanders within the
required time period. In this case, the project proponent must coordinate the timing
of disturbance of the breeding habitat to allow USFWS or CDFW to translocate the
individuals. USFWS and CDFW shall be allowed 45 days to translocate individuals
from the date the first written notification was submitted by the project proponent
(or a longer period agreed to by the project proponent, USFWS, and CDFW).
MM-BIO-5: Rare Plant Surveys and Mitigation. Prior to commencement of any project-related
construction activity, Contra Costa County shall retain a qualified biologist/botanist
to conduct protocol-level special-status plant surveys of the undisturbed areas of
the project site for alkali milk-vetch (Astragalus tener var. tener), brittlescale
(Atriplex depressa), big tarplant (Blepharizonia plumosa), round-leaved filaree
(California macrophylla), Congdon’s tarplant (Centromadia parryi ssp.
congdonii), recurved larkspur (Delphinium recurvatum), spiny-sepaled button-
celery (Eryngium spinosepalum), diamond-petaled poppy (Eschscholzia
rhombipetala), and Contra Costa goldfields (Lasthenia conjugens).
As part of the East Contra Costa County Habitat Conservation Plan (HCP)/Natural
Community Conservation Plan (NCCP) application for coverage, the surveys shall
be conducted during the appropriate blooming periods. The surveys shall be
conducted by a qualified biologist knowledgeable of the plant species in the region.
These plant surveys shall be conducted in accordance with 2009 California
Department of Fish and Wildlife (CDFW) rare plant survey protocols.
If any special-status plant species are observed during surveys, the project
proponent shall notify the HCP/NCCP Implementing Entity (i.e., East Contra Costa
County Habitat Conservancy) of the construction schedule so as to allow the
HCP/NCCP Implementing Entity the option to salvage the population(s) in
accordance with HCP/NCCP Conservation Measure 3.10 (Plant Salvage when
Impacts are Unavoidable) described below. Additionally, the project proponent
shall confirm with the HCP/NCCP Implementing Entity that the take limits of the
HCP/NCCP for the species identified have not been reached.
The following special-status plant species with potential to occur on the project site
are covered by the HCP/NCCP: brittlescale, big tarplant, round-leaved filaree, and
14
recurved larkspur. Alkali milk-vetch, diamond-petaled poppy, and Contra Costa
goldfields are analyzed in the HCP/NCCP but are “no take” species, and avoidance
is the only acceptable mitigation measure.
Congdon’s tarplant and spiny-sepaled button-celery are not addressed in the
HCP/NCCP. For these plants, mitigation shall consist of, in order of preference, (1)
avoidance, (2) salvage and transplant as described below, or (3) off-site habitat
enhancement or restoration in consultation with CDFW.
Plant Salvage when Impacts are Unavoidable (Covered Species)
Perennial Covered Plants
Where impacts to covered plant species cannot be avoided and plants will be
removed by approved covered activities, the HCP/NCCP Implementing Entity has
the option of salvaging the covered plants. Salvage methods for perennial species
shall be tested for whole individuals, cuttings, and seeds. Salvage measures shall
include the evaluation of techniques for transplanting as well as germinating seed
in garden or greenhouse and then transplanting to suitable habitat sites in the field.
Techniques shall be tested for each species, and appropriate methods shall be
identified through research and adaptive management. Where plants are
transplanted or seeds distributed to the field they shall be located in preserves in
suitable habitat to establish new populations. Field trials shall be conducted to
evaluate the efficacy of different methods and determine the best methods to
establish new populations. New populations shall be located such that they
constitute separate populations and do not become part of an existing population of
the species, as measured by the potential for genetic exchange among individuals
through pollen or propagule (e.g., seed, fruit) dispersal.
Transplanting within the preserves shall only minimally disturb existing native
vegetation and soils. Supplemental watering may be provided as necessary to
increase the chances of successful establishment, but must be removed following
initial population establishment. See also All Covered Plants, below.
Annual Covered Plants
For annual covered plants, mature seeds shall be collected from all individuals for
which impacts cannot be avoided (or if the population is large, a representative
sample of individuals). If storage is necessary, seed storage studies shall be
conducted to determine the best storage techniques for each species. If needed,
studies shall be conducted on seed germinated and plants grown to maturity in
15
garden or greenhouse to propagate larger numbers of seed. Seed propagation
methods shall ensure that genetic variation is not substantially affected by
propagation (i.e., selection for plants best adapted to cultivated conditions). Field
studies shall be conducted through the Adaptive Management Program to
determine the efficacy and best approach to dispersal of seed into suitable habitat.
Where seeds are distributed to the field, they shall be located in preserves in suitable
habitat to establish new populations. If seed collection methods fail (e.g., due to
excessive seed predation by insects), alternative propagation techniques shall be
necessary. See also All Covered Plants, below.
All Covered Plants
All salvage operations shall be conducted by the HCP/NCCP Implementing Entity.
To ensure enough time to plan salvage operations, project proponents shall notify
the HCP/NCCP Implementing Entity of their schedule for removing the covered
plant population.
The HCP/NCCP Implementing Entity may conduct investigations into the efficacy
of salvaging seeds from the soil seed bank for both perennial and annual species.
The soil seed bank may add to the genetic variability of the population. Covered
species may be separated from the soil though garden/greenhouse germination or
other appropriate means. Topsoil taken from impact sites shall not be distributed
into preserves because of the risk of spreading new non-native and invasive plants
to preserves.
The HCP/NCCP Implementing Entity will transplant new populations such that
they constitute separate populations and do not become part of an existing
population of the species, as measured by the potential for genetic exchange among
individuals through pollen or propagule (e.g., seed, fruit) dispersal. Transplanting
or seeding “receptor” sites (i.e., habitat suitable for establishing a new population)
should be carefully selected on the basis of physical, biological, and logistical
considerations (Fiedler and Laven 1996); some examples of these are listed below:
• Historic range of the species.
• Soil type.
• Soil moisture.
• Topographic position, including slope and aspect.
• Site hydrology.
• Mycorrhizal associates (this may be important for Mount Diablo manzanita).
• Presence or absence of typical associated plant species.
• Presence or absence of herbivores or plant competitors.
16
• Site accessibility for establishment, monitoring, and protection from trampling
by cattle or trail users.
Finding
The County Board of Supervisors finds that the above mitigation measures are feasible, will reduce
the potential biological resource impact (Impact 3.3-1) of the project to a less-than-significant
level, and is adopted by the County Board of Supervisors. Accordingly, the County Board of
Supervisors finds, that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA
Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into,
the project, which avoid or substantially lessen the significant environmental effect as identified
in the Final EIR.
Rationale
While only three special status wildlife species, and no special status plants, were detected in the
project area, there is potential habitat on or directly adjacent to the project site. Therefore, the
proposed mitigation measures would require pre-construction surveys. If species are detected,
avoidance measures and monitoring would be implemented to reduce the potential impacts to
special-status wildlife. For nesting Swainson’s hawk, mitigation may include replacement of
nesting trees. For burrowing owls, if occupied burrows cannot be avoided, passive relocation
(exclusion) may be utilized outside of the breeding season. For California red-legged frog and
California tiger salamander, individuals may be translocated in coordination with USFWS and
CDFW. Mitigation for special status plants includes avoidance and replanting protocols. With
implementation of the mitigation measures, the potential impact would be reduced to less than
significant.
Substantial adverse effect on riparian habitat or other sensitive natural community identified in
local or regional plans, policies, regulations or by the California Department of Fish and
Wildlife or U.S. Fish and Wildlife Service. (Impact 3.3-2). Most areas directly adjacent to the
existing airport and to the north and east of the existing runways consist of non-native annual
grassland. Sensitive vegetation communities, including wetlands and alkali grasslands, occur
within the project site and, under the HCP/NCCP, would require either avoidance or other
mitigation. Sensitive resources and habitats include vernal pools, seasonal wetlands, alkali
wetlands, and drainages, all of which are potentially jurisdictional features regulated by CDFW,
USFWS, and ACOE. Construction of the proposed project could result in direct habitat destruction
or modification, which is a potentially significant impact.
Mitigation Measures
MM-BIO-6: a. Wetlands and Waters of the United States or State. Prior to commencement of
any project-related construction activity, Contra Costa County (County) shall retain
17
a qualified biologist or wetland scientist to prepare a jurisdictional delineation of
the project site to determine the extent of potentially jurisdictional features within
the project disturbance area. Impacts to wetlands and other waters of the United
States or waters of the state shall require authorization from the U.S. Army Corps
of Engineers in the form of a Clean Water Act (CWA) Section 404 Permit, from
the Regional Water Quality Control Board in the form of a CWA Section 401 Water
Quality Certification, and the California Department of Fish and Wildlife in the
form of a California Fish and Game Code Section 1602 Streambed Alteration
Agreement. Such permits typically include measures to avoid and minimize or
mitigate impacts. Where avoidance of jurisdictional wetlands or waters is not
feasible, replacement of resources is required in the form of restoration or creation.
The project shall seek coverage under the East Contra Costa County Habitat
Conservation Plan (HCP)/Natural Community Conservation Plan (NCCP) for
impacts to jurisdictional waters or wetlands. If neither avoidance nor coverage
under the HCP/NCCP is feasible, the County shall comply with the requirements
of the 404 permit coverage for on- or off-site mitigation, at a replacement ration of
no less than 1:1.
b. Brushy Creek Setback. Per the requirements of the HCP/NCCP and Contra
Costa County General Plan policy, a development setback of 75 feet from Brushy
Creek (measured from top of bank) is required. Note that a lesser setback (for an
area less than 300 linear feet) may be approved in consultation with the East Contra
Costa Habitat Conservancy.
MM-BIO-7: Alkali Grassland Avoidance and Mitigation. A portion of the aviation
development area, adjacent to the existing facilities, includes alkali grassland.
Ultimate development of this site shall require either avoidance, or establishment
of like alkali grassland outside of the development area, which shall be made under
consultation with the East Contra Costa County Habitat Conservancy. Because this
area is relatively disturbed, is isolated from similar habitat, and is maintained on an
on-going basis by airport staff, it does not represent an exemplary patch of alkali
grassland. Mitigation ratios for impacts to alkali grassland will be determined in
consultation with the East Contra Costa County Habitat Conservancy.
MM-BIO-8: San Joaquin Kit Fox Preconstruction Surveys, Avoidance and Minimization,
and Construction Monitoring. Prior to any ground disturbance related to covered
activities, a USFWS/CDFW– approved biologist shall conduct a preconstruction
survey in areas identified in the planning surveys as supporting suitable breeding
or denning habitat for San Joaquin kit fox. The surveys shall establish the presence
or absence of San Joaquin kit foxes and/or suitable dens and evaluate use by kit
foxes in accordance with USFWS survey guidelines.
18
Preconstruction surveys shall be conducted within 30 days of ground disturbance.
On the parcel where the activity is proposed, the biologist shall survey the proposed
disturbance footprint and a 250-foot radius from the perimeter of the proposed
footprint to identify San Joaquin kit foxes and/or suitable dens. Adjacent parcels
under different land ownership shall not be surveyed. The status of all dens shall be
determined and mapped. Written results of preconstruction surveys shall be
submitted to USFWS within 5 working days after survey completion and before the
start of ground disturbance. Concurrence is not required prior to initiation of
covered activities.
If San Joaquin kit foxes and/or suitable dens are identified in the survey area, the
measures described below shall be implemented.
• If a San Joaquin kit fox den is discovered in the proposed development
footprint, the den shall be monitored for 3 days by a USFWS/CDFW– approved
biologist using a tracking medium or an infrared beam camera to determine if
the den is currently being used.
• Unoccupied dens should be destroyed immediately to prevent subsequent use.
• If a natal or pupping den is found, USFWS and CDFW shall be notified
immediately. The den shall not be destroyed until the pups and adults have
vacated and then only after further consultation with USFWS and CDFW.
• If kit fox activity is observed at the den during the initial monitoring period, the
den shall be monitored for an additional 5 consecutive days from the time of
the first observation to allow any resident animals to move to another den while
den use is actively discouraged. For dens other than natal or pupping dens, use
of the den can be discouraged by partially plugging the entrance with soil such
that any resident animal can easily escape. Once the den is determined to be
unoccupied it may be excavated under the direction of the biologist.
Alternatively, if the animal is still present after 5 or more consecutive days of
plugging and monitoring, the den may have to be excavated when, in the
judgment of a biologist, it is temporarily vacant (i.e., during the animal’s normal
foraging activities).
If dens are identified in the survey area outside the proposed disturbance footprint,
exclusion zones around each den entrance or cluster of entrances shall be
demarcated. The configuration of exclusion zones should be circular, with a radius
measured outward from the den entrance(s). No covered activities shall occur
within the exclusion zones. Exclusion zone radii for potential dens shall be at least
50 feet and shall be demarcated with four to five flagged stakes. Exclusion zone
radii for known dens shall be at least 100 feet and shall be demarcated with staking
19
and flagging that encircles each den or cluster of dens but does not prevent access
to the den by kit fox.
MM-BIO-9: East Contra Costa County HCP/NCCP Covered Shrimp Preconstruction
Survey, Avoidance and Minimization, and Construction Monitoring. Prior to
any ground disturbance related to covered activities, a USFWS-approved biologist
shall conduct a preconstruction survey in areas identified in the planning surveys
as having suitable shrimp habitat. The surveys shall establish the presence or
absence of covered shrimp and/or habitat features and evaluate use by listed shrimp
in accordance with modified USFWS survey guidelines (USFWS 1996a). Project
proponents are required to conduct USFWS protocol surveys in 1 year (rather than
2) to determine presence or absence of listed shrimp species. If covered shrimp are
absent from the site, there are no further requirements related to covered shrimp. If
covered shrimp are present, the following avoidance and minimization and
construction monitoring measures are required.
• To the maximum extent practicable, impacts on occupied habitat of covered
shrimp shall be avoided by implementing the following measures based on
existing mitigation standards (USFWS 1996b).
• If suitable habitat for covered shrimp will be retained on site, establish a buffer
(described below) from the outer edge of all hydric vegetation associated with
seasonal wetlands occupied by covered shrimp. Alternatively, at the request of
the project proponent, representatives of the East Contra Costa County Habitat
Conservancy and USFWS may conduct site visits to inspect the particular
characteristics of specific project sites and may approve reductions of the
buffer. Buffer reductions may be approved for all or portions of the site
whenever reduced setbacks will maintain the hydrology of the seasonal wetland
and achieve the same or greater habitat values as would be achieved by the
original buffer.
• Activities inconsistent with the maintenance of seasonal wetlands within the
buffers and disturbance of the on-site watershed shall be prohibited.
Inconsistent activities include altering existing topography; placing new
structures within the buffers; dumping, burning, and/or burying garbage or any
other wastes or fill materials; building new roads or trails; removing or
disturbing existing native vegetation; installing storm drains; and using
pesticides or other toxic chemicals.
• Filling of seasonal wetlands, if unavoidable, shall be delayed until pools are dry
and samples from the top 4 inches of wetland soils are collected. Soil collection
will shall be sufficient to include a representative sample of plant and animal
life present in the wetland by incorporating seeds, cysts, eggs, spores, and
similar inocula. The amount of soil collected shall be determined by the size of

the wetland filled and the variation in physical and biological conditions within
the wetland. The number and size of samples shall be sufficient to capture this
variation. For very small wetlands it may be most cost effective to simply
collect all topsoil. These samples shall be provided to the East Contra Costa
County Habitat Conservancy so that the soil can be translocated to suitable
habitat within the inventory area unoccupied by covered shrimp or used to
inoculate newly created seasonal wetlands on preserve lands.
• Seasonal wetlands occupied by covered shrimp that are filled shall be offset by
preserving or acquiring seasonal wetlands occupied by the covered shrimp
species and restoring habitat suitable for the covered shrimp species in
accordance with Conservation Measure 3.8. Such mitigation shall supersede
requirements for mitigation of impacts on wetland habitat when covered species
are present.
If suitable habitat for covered shrimp shall be retained on site, project proponents
shall establish a buffer from the outer edge of all hydric vegetation associated with
seasonal wetlands occupied (or assumed to be occupied) by covered shrimp. This
buffer zone shall be determined in the field by the biologists as the immediate
watershed feeding the seasonal wetland or a minimum of 50 feet, whichever is
greater. Buffers shall be marked by brightly colored fencing or flagging throughout
the construction process. Activities shall be prohibited within this buffer in
accordance with the minimization measure above.
Construction personnel shall be trained to avoid affecting shrimp. A qualified
biologist approved by USFWS shall inform all construction personnel about the life
history of covered shrimp, the importance of avoiding their habitat, and the terms
and conditions of the Eastern Contra Costa County Habitat Conservation
Plan/Natural Community Conservation Plan related to avoiding and minimizing
impacts on covered shrimp
Finding
The County Board of Supervisors finds that the above mitigation measures are feasible, will reduce
the potential biological resource impact (Impact 3.3-2) of the project to a less-than-significant
level, and is adopted by the County Board of Supervisors. Accordingly, the County Board of
Supervisors finds that, pursuant to Public Resources Code Section 21081(a)(1) and the CEQA
Guidelines Section 15091(a)(1), changes or alterations have been required in or incorporated into
the project, which avoid or substantially lessen the significant environmental effect as identified
in the Final EIR.
21
Rationale
The proposed mitigation measures would require that a wetlands delineation is performed and
avoidance buffers around potentially jurisdictional resources are established prior to construction,
and also implements a setback from Brushy Creek. Mitigation measures would also require that
alkali grassland on site is avoided and would reduce impacts to sensitive natural communities.
Surveys for San Joaquin kit fox would be required and, if detected, avoidance measures and
monitoring would be implemented. If wetlands containing covered shrimp species, including
longhorn fairy shrimp, vernal pool fairy shrimp, conservancy fairy shrimp, and vernal pool tadpole
shrimp, cannot be avoided, samples of wetland soils provided to the East Contra Costa County
Habitat Conservancy for translocation. In addition, compensation for wetlands habitat would be
provided, either on or off-site. With implementation of the above discussed mitigation measures,
the potential impact would be reduced to less than significant.
Substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean
Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct
removal, filling, hydrological interruption, or other means. (Impact 3.3-3). Potential impacts
from the project could occur through the construction of the proposed project involving the
removal, filing, and/or hydrological interruption of protected wetlands.
Mitigation Measure
MM-BIO-6: See above.
Finding
The County Board of Supervisors finds that the above mitigation measure is feasible, will reduce
the potential biological resource impact (Impact 3.3-3) of the project to a less-than-significant
level, and is adopted by the County Board of Supervisors. Accordingly, the County Board of
Supervisors finds, that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA
Guidelines Section 15091(a)(1), changes or alterations have been required in, or incorporated into,
the project, which avoid or substantially lessen the significant environmental effect as identified
in the Final EIR.
Rationale
The proposed mitigation measures require a detailed jurisdictional delineation to be performed by
a qualified biologist or wetland scientist prior to project development activities. If jurisdictional
features would be impacted by the project, authorization from the resource agencies listed above
would be required in the form of wetland permits (e.g., 404 Nationwide Permit, 401 Water Quality
Certification, and 1602 Streambed Alteration Agreement respectively). Required compensatory
22
mitigation would provide no net loss of jurisdictional habitats. With implementation of the
mitigation measure, the potential impact would be reduced to less than significant.
Cultural Resources
Substantial adverse change in the significance of a historic resource as defined in CEQA
Guidelines Section 15064.5. (Impact 3.4-1). Due to the presence of cultural resources within the
eastern portion of the project site, it is possible that historical resources would inadvertently be
discovered during construction.
Mitigation Measure
MM-CUL-1: Accidental Discovery of Archaeological Resources. Prior to commencement of
any construction activities involving ground disturbance, Contra Costa County, a
qualified archaeologist, representatives from interested Native American Tribes,
and the construction contractor shall be invited to meet or otherwise discuss by
conference call the project site’s archaeological sensitivity and determine the
duration and extent of monitoring for archaeological deposits that may be
uncovered during construction. Given the present disturbed condition in some
locations surrounding existing airport facilities, areas of elevated potential for
encountering unanticipated resources should be considered those within 500 feet of
the historic-era corral and Brushy Creek, and no deeper than 4 feet below the
present ground surface. An archaeological monitor and a monitor from a culturally
affiliated Native American Tribe shall be present for initial ground-disturbing work
in these areas, after which the monitoring frequency shall be reduced to periodic
spot-checks elsewhere. The monitoring strategy shall be adjusted (increased,
decreased, or discontinued) based on the results of monitoring within areas of
elevated archaeological sensitivity and as recommended by a qualified
archaeologist meeting the Secretary of the Interior’s Professional Qualification
Standards, in consultation with culturally affiliated Native American Tribes. In the
event that archaeological resources are exposed, work within 100 feet of the find
shall be halted or directed to another location until a qualified archaeologist can
evaluate the significance of the find. If the resources are determined to be historical
resources or unique (pursuant to Section 15064.5 of the CEQA Guidelines), the
qualified archaeologist shall make recommendations prioritizing resource
avoidance, or, where avoidance is infeasible, data recovery.
Finding
The County Board of Supervisors finds that the above mitigation measure is feasible, will reduce
the potential cultural resource impact (Impact 3.4-1) of the project to a less-than-significant level,
and is adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors
23
finds, that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines
Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project,
which avoid or substantially lessen the significant environmental effect as identified in the Final
EIR.
Rationale
No identified historic resources would be affected by the project. However, the project site includes
areas of cultural sensitivity, which results in potential for accidental discovery of previously
unidentified resources. The proposed mitigation measure requires a qualified archaeologist
determine the duration and extent of monitoring for archaeological deposits that may be uncovered
during construction. An archaeological monitor shall be present for initial ground-disturbing work
in sensitive areas and if resources are found, work shall be halted and the historic significance of
the find evaluated. If the resource is determined to be historically significant, avoidance measures
would be implemented or, if avoidance is infeasible, data recovery.
Substantial adverse change in the significance of an archaeological resource as defined in
CEQA Guidelines Section 15064.5. (Impact 3.4-2). The Cultural Resources Inventory Report
performed for the project suggests that there is moderate potential for inadvertent discovery of
intact cultural deposits during earth moving activities. Because of this, the project would have a
potentially significant impact on archaeological resources.
Mitigation Measures
MM-CUL-1: See above.
Finding
The County Board of Supervisors finds that the above mitigation measure is feasible, will reduce
the potential cultural resource impact (Impact 3.4-2) of the project to a less-than-significant level,
and is adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors
finds, that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines
Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project,
which avoid or substantially lessen the significant environmental effect as identified in the Final
EIR.
Rationale
No identified significant archaeological resources would be affected by the project. However, the
project site includes areas of cultural sensitivity, which results in potential for accidental discovery
of previously unidentified resources. The proposed mitigation measure requires a qualified
archaeologist determine the duration and extent of monitoring for archaeological deposits that may
24
be uncovered during construction. An archaeological monitor shall be present for initial ground-
disturbing work in sensitive areas and if resources are found, work shall be halted and the cultural
significance of the find evaluated. If the resource is determined to be significant, avoidance
measures would be implemented or, if avoidance is infeasible, data recovery.
Disturbance of human remains, including those interred outside of dedicated cemeteries.
(Impact 3.4-3). It is possible that human remains would inadvertently be discovered during
construction. Disturbance of previously unidentified human remains would be a potentially
significant impact.
Mitigation Measure
MM-CUL-2: Accidental Discovery of Human Remains. Pursuant to Section 5097.98 of the
California Public Resources Code and Section 7050.5 of the California Health and
Safety Code, as well as California Environmental Quality Act Guidelines Section
15064.5(e), in the event of the discovery of human remains, work shall be
suspended within 100 feet of the find, and the Contra Costa County (County)
Coroner/Sheriff shall be immediately notified. The County Coroner/Sheriff shall
determine if an investigation is necessary. If the remains are determined to be
Native American:
1. The Coroner shall contact the Native American Heritage Commission (NAHC)
within 24 hours.
2. The NAHC shall identify the person or persons it believes to be the most likely
descendant (MLD) from the deceased Native American.
3. The MLD shall have an opportunity to make a recommendation to the County for
means of treating or disposing of, with appropriate dignity, the human remains and
any associated grave goods as provided in California Public Resources Code
Section 5097.98.
Finding
The County Board of Supervisors finds that the above mitigation measure is feasible, will reduce
the potential cultural resource impact (Impact 3.4-3) of the project to a less-than-significant level,
and is adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors
finds, that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines
Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project,
which avoid or substantially lessen the significant environmental effect as identified in the Final
EIR.
25
Rationale
While no sites containing human remains have been identified, accidental discovery of human
remains is a potential impact of project construction. The proposed mitigation measure requires
that in the event of the discovery of human remains that construction be suspended and the County
and NAHC be notified to determine appropriate treatment. With implementation of the mitigation
measure, the potential impact would be reduced to less than significant.
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.. (Impact 3.4-4). One prehistoric
resource has been previously located on the project site. The presence of this resource and the
proximity of Byron Hot Springs to the project site indicates there is the potential to inadvertently
encounter tribal cultural resources during construction.
Mitigation Measure
MM-CUL-3: Should a potential tribal cultural resource (TCR) be inadvertently encountered,
construction activities within 100 feet of the TCR shall be halted and Contra Costa
County Department of Conservation and Development (Department) notified. The
Department shall notify Native American tribes that have been identified by the
Native American Heritage Commission to be traditionally and culturally affiliated
with the geographic area of the project. Any affected tribe shall be provided a
reasonable period of time to conduct a site visit and make recommendations
regarding future ground disturbance activities as well as the treatment and
disposition of any discovered TCR. Depending on the nature of the potential
resource and tribal recommendations, review by a qualified archaeologist may be
required. Implementation of proposed recommendations shall be made based on the
determination of the County that the approach is reasonable and feasible. All
activities shall be conducted in accordance with regulatory requirements.
MM-CUL-4: Worker Environmental Awareness Program (WEAP).
The County shall require the contractor to provide a cultural resources and tribal
cultural resources sensitivity and awareness training program (Worker
Environmental Awareness Program [WEAP]) for all personnel involved in project
construction, including field consultants and construction workers. The WEAP
shall be developed in coordination with an archaeologist meeting the Secretary of
the Interior’s Professional Qualifications Standards for Archeology, as well as
culturally affiliated Native American tribes. The County will invite Native
American representatives from interested culturally affiliated Native American
26
tribes to participate. The WEAP shall be conducted before any ground-disturbing
construction activities begin at the project site. The WEAP shall include relevant
information regarding sensitive cultural resources and tribal cultural resources,
including applicable regulations, protocols for avoidance, and consequences of
violating State laws and regulations.
The WEAP shall also describe appropriate avoidance and impact minimization
measures for cultural resources and tribal cultural resources that could be located
at the project site and shall outline what to do and who to contact if any potential
cultural resources or tribal cultural resources are encountered. The WEAP shall
emphasize the requirement for confidentiality and culturally appropriate treatment
of any discovery of significance to Native Americans and shall discuss appropriate
behaviors and responsive actions, consistent with Native American tribal values.
Finding
The County Board of Supervisors finds that the above mitigation measure is feasible, will reduce
the potential cultural resource impact (Impact 3.4-4) of the project to a less-than-significant level,
and is adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors
finds, that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines
Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project,
which avoid or substantially lessen the significant environmental effect as identified in the Final
EIR.
Rationale
No tribal cultural resources have been identified within the project development areas. However,
the project site includes areas of cultural sensitivity, which results in potential for accidental
discovery of previously unidentified resources. The County notified California Native American
tribes culturally affiliated with the project area, per Assembly Bill (AB) 52 and Senate Bill 18. A
request for consultation was received from Wilton Rancheria on August 30, 2017. The County
responded within the required 30-day period on September 7, 2017, and again on February 22,
2018, but no response was received from the tribe. During the public comment period for the Draft
EIR, an additional consultation request letter was received by the County from the Wilton
Rancheria on July 14, 2021. The County re-opened consultation on September 22, 2021. Although
no tribal cultural resources were identified within the project site, minor modifications were made
to the mitigation measures addressing accidental discovery of tribal cultural resources.
Consultation was again closed on January 21, 2022.
The proposed mitigation measures, as revised through the AB 52 consultation process, require that
in the event of the discovery of potential tribal cultural resources that construction be halted and
the County, NAHC, and Native American tribes be notified to determine if further investigation is
27
required. The mitigation measures also require that workers operating within the project area
receive environmental awareness training on identification of potential resources and procedures
if a potential resource is discovered. With implementation of the mitigation measures, the potential
impact would be mitigated to less than significant.
Geology, Soils, and Minerals
The project would be located on expansive soils as defined in Table 18-1-B of the Uniform
Building Code (Impact 3.5-4). The Quaternary Alluvium underlying the project site possesses the
potential for expansive clays. Building damage due to volume changes associated with expansive
soils can be reduced by placing building slabs on select, granular fill and by use of rigid mat or
post-tensioned slabs. The project could be subject to substantial direct or indirect risks to life or
property.
Mitigation Measure
MM-GEO-1: Prior to the approval of any building or improvement plans, a geotechnical report
shall be prepared by a registered civil or geotechnical engineer and submitted to the
County Department of Conservation and Development. The report shall address the
specific approach to development. This report shall: (A) provide specific criteria
and standards for identifying suitable imported fill materials; (B) if import fills may
be expansive or corrosive, provisions shall be made for the import fill materials;
(B) if import fills may be expansive or corrosive, provisions shall be made for
testing of soils on rough-graded pads and providing design measures to
avoid/control damage to foundations and buried utilities; (C) provide criteria for
placement of engineered fill; (D) provide further evaluation of seismic settlement
and other types of seismically induced ground failure by recognized methods
appropriate to soil conditions discovered during subsurface investigation; (E)
provide detailed evaluation of the compressibility of the alluvial soils and forecast
the anticipated amount of total settlement and timing of settlement to occur or
placing a surcharge on the site to speed settlement; (F) provide California Building
Code seismic parameters; and (G) outline recommendations for geotechnical
observation and testing services during site preparation-, grading-and foundation-
related work. Improvement, grading, and building plans shall carry out the
recommendations of the approved report.
Finding
The County Board of Supervisors finds that the above mitigation measure is feasible, will reduce
the potential geological impact (Impact 3.5-4) of the project to a less-than-significant level, and is
adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors finds,
that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines Section
28
15091(a)(1), changes or alterations have been required in, or incorporated into, the project, which
avoid or substantially lessen the significant environmental effect as identified in the Final EIR.
Rationale
The proposed mitigation measure requires the preparation of a geotechnical report specific to
project development that would include recommendations on foundation designs and provide
recommendation to prevent damage from expansive soils. These recommendations would be
incorporated into the project design prior to the approval of building or improvement plans. The
geotechnical study would be required to comply with applicable building codes and engineering
standards, including any applicable amendments to the CBC contained in the County’s municipal
code. With implementation of the mitigation measure, the potential impact would be reduced to
less than significant.
The project may 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 (Impact 3.5-6). The project site is currently serviced by a 3,000-gallon septic tank and
lift station that pumps to a leach field. Under proposed project conditions, one or a combination of
the following scenarios may occur: the existing septic tank would be expanded to support the
additional development areas on the project site, the existing septic system would be converted to
a package wastewater treatment plant, and/or the project site would connect to the Byron Sanitary
District system. The underlying soils possess expansive potential, which pose a potentially
significant impact.
Mitigation Measures
MM-GEO-1: See above.
Finding
The County Board of Supervisors finds that the above mitigation measure is feasible, will reduce
the potential geological impact (Impact 3.5-5) of the project to a less-than-significant level, and is
adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors finds,
that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines Section
15091(a)(1), changes or alterations have been required in, or incorporated into, the project, which
avoid or substantially lessen the significant environmental effect as identified in the Final EIR.
Rationale
A septic system is currently operating onsite. However, potential soil limitations could affect the
operation of new or expanded facilities. The proposed mitigation measure requires the preparation
of a geotechnical report specific to project development that would include recommendations on
foundation designs and provide recommendation to prevent damage from expansive soils. These
29
recommendations would be incorporated into the project design prior to the approval of building
or improvement plans. The geotechnical study would be required to comply with applicable
building codes and engineering standards, including any applicable amendments to the CBC
contained in the County’s municipal code. With implementation of the above discussed mitigation
measure, the potential impact would be reduced to less than significant.
The project would not directly or indirectly destroy a unique paleontological resource or site or
unique geologic feature (Impact 3.5-4). The project site contains sedimentary units with moderate
to high paleontological resources sensitivity. Therefore, it is possible that paleontological
resources would inadvertently be discovered during construction.
Mitigation Measure
MM-GEO-2: If paleontological resources (i.e., fossil bones, teeth, shells, plants, or trace fossils)
are exposed during construction activities for the project, all construction work
occurring within 100 feet of the find shall immediately stop until a qualified
paleontologist, meeting the Society of Vertebrate Paleontology standards, can
evaluate the significance of the find and determine whether or not additional study
is warranted. The paleontologist shall be empowered to temporarily stop or redirect
grading activities to allow removal of abundant or large paleontological resources.
Depending upon the significance of the find, the qualified paleontologist may
simply remove and record the find and allow work to continue. If the discovery
proves significant under the California Environmental Quality Act, additional
work, such as data recovery and extended specimen removal, may be warranted.
The qualified paleontologist shall prepare a Paleontological Resources Impact
Mitigation Program for the project, which outlines where paleontological
monitoring is required based on the location of the discovery, geotechnical reports,
and construction plans. The qualified paleontologist shall also be required to curate
specimens in a repository with permanent retrievable storage and submit a final
written report to the repository and lead agency for review.
Finding
The County Board of Supervisors finds that the above mitigation measure is feasible, will reduce
the potential paleontological impact (Impact 3.5-6) of the project to a less-than-significant level,
and is adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors
finds, that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines
Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project,
which avoid or substantially lessen the significant environmental effect as identified in the Final
EIR.
30
Rationale
While no significant paleontological resources have been identified, the proposed mitigation
measure requires that in the event that scientifically important paleontological resources are
unearthed during grading activities, a paleontologist should be retained to evaluate the discovery
and make a significance determination, and if significant, make recommendations for
conservation. With implementation of the above discussed mitigation measure, the potential
impact would be reduced to less than significant.
Hazards and Hazardous Materials
The project has the potential to 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 (Impact 3.7-2). While there have been no known
releases to the subsurface causing contamination (there have been minor releases from drums and
a fuel release to the surface that was cleaned up), it is possible that subsurface
releases/contamination have occurred in areas of fuel/oil storage and use. Construction activities
in these areas could result in encountering contaminated soil and/or groundwater. Exposure of
contaminated soils to workers and the surrounding environment would result in potentially
significant impacts. Also, an area in the eastern portion of the project site was used for agriculture
from the 1960s until the 1980s. Pesticides may have been used at the project site during this time.
Exposure of pesticide-contaminated soils to workers and the surrounding environment during
grading and construction would result in potentially significant impacts.
Mitigation Measures
MM-HAZ-1: Prior to initiation of grading and construction, a Hazardous Materials Contingency
Plan shall be in-place and consist of the following:
• Identification of areas of potential fuel- or oil-impacted soils on a site plan.
• Protocol for identifying suspected contaminated soils (e.g., discoloring, odor,
positive photoionization detector readings), utilizing personnel trained in
recognition of contaminated soils/groundwater and certified with respect to
Occupational Safety and Health Administration Hazardous Waste Operations
and Emergency Response (i.e., OSHA HAZWOPER training).
• Procedures for notification and reporting, including internal management and
to Contra Costa Environmental Health Department and local agencies, as
needed.
• Procedures for temporary cessation of construction activity and evaluation of
the level of environmental concern.
• Procedures for limiting access to the contaminated area to personnel with
OSHA HAZWOPER training.
31
• A worker health and safety plan for excavation of contaminated soil and/or
groundwater.
• Procedures for characterizing, managing, and disposing of potentially
contaminated soils.
MM-HAZ-2: Prior to development of the former agricultural areas identified in Figure 3.7-1,
Hazards Site Map, soil samples shall be collected and tested for pesticides. Shallow
soil samples shall be collected from the upper 0.5 to –1.0 foot of ground surface
from the site soils and analyzed for organochlorine pesticides by U.S.
Environmental Protection Agency (EPA) Method 8081A and arsenic by EPA
Method 6010B. The soil samples shall be analyzed by a California Environmental
Laboratory Accreditation Program-certified laboratory.
The pesticide sampling data shall be compared to applicable regulatory threshold
levels such as the EPA Regional Screening Levels and the Department of Toxic
Substances Control Human and Ecological Risk Office Note 3 screening levels.
The arsenic sampling data shall be compared to California typical background
levels, such as those in the 1996 Kearney Foundation Special Report on
Background Concentrations of Trace and Major Elements in California Soils.
If the soil sampling concentrations, using the 95% upper confidence level or other
statistical evaluation, exceed the screening level, mitigation shall include removal
of impacted soil for off-site disposal prior to or during construction grading. A soil
management plan, including a health and safety plan, shall be prepared to properly
manage the excavated soil and protect worker and public health and safety.
Finding
The County Board of Supervisors finds that the above mitigation measures are feasible, will reduce
the potential hazards impact (Impact 3.7-2) of the project to a less-than-significant level, and is
adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors finds,
that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines Section
15091(a)(1), changes or alterations have been required in, or incorporated into, the project, which
avoid or substantially lessen the significant environmental effect as identified in the Final EIR.
Rationale
While there have been no known releases to the subsurface causing contamination, it is possible
that unidentified contamination is present due to the historical activities of the site. The proposed
mitigation measures require the preparation of a Hazardous Materials Contingency Plan and soil
sampling, analysis, and potential remediation of soils in the identified former agricultural area.
These measures would protect on-site workers and visitors and would require adequate clean-up
32
based on the proposed uses. With implementation of the above discussed mitigation measures, the
potential impact would be reduced to less than significant.
Hydrology and Water Quality
The project has the potential to substantially alter the existing drainage pattern of the site or
area, including through the alteration of the course of a stream or river or through the addition
of impervious surfaces, in a manner which would: (a) result in substantial erosion or siltation
on or off site; (b) substantially increase the rate or amount of surface runoff in a manner which
would result in flooding on- or off-site; (c)create or contribute runoff water which would exceed
the capacity of existing or planned stormwater drainage systems or provide substantial
additional sources of polluted runoff; or (d) impede or redirect flood flows (Impact 3.8-3). The
project would involve substantial increases in the amount of impervious surfaces, which has the
potential to substantially increase the rate and volume of storm runoff during peak storm events
without adequate measures to detain, retain, or slow the increased flows.
Mitigation Measures
MM-HYD-1: Hydrology and Drainage Study. Prior to approval of individual development
plans, a Hydrology and Drainage Study shall be prepared for the project to refine
the size and hydrologic characteristics of drainage areas that intersect the project
site, to estimate pre- and post-project flow rates and volumes under 10- 25-, 50-
and 100-year storm events, and to provide recommendations for needed
improvements. The Hydrology and Drainage Study shall quantify the capacity of
the existing detention basin; determine whether or not it will be sufficient to serve
future land uses; and establish the hydrology performance criteria and design
standards applicable to potential future tenants, based on the destination of runoff
(i.e., detention basin or Bushy Creek) and the degree of impervious surface
coverage. The study shall be consistent with the hydrology performance criteria and
design standards contained within the Contra Costa County Drainage Ordinance
(Division 914), which include but are not limited to:
• Drainage facilities shall be designed to convey a minimum (with sufficient
freeboard) of the runoff produced by a) a 10-year storm event for facilities
draining an area of less than 1 square mile, b) a 25-year storm event for facilities
draining an area of between 1 and 4 square miles, and c) a 50-year storm event
(and 100-year event without freeboard) for facilities draining an area of more
than 4 square mile.
• Finished floors shall be elevated above the base flood elevation of the one-
hundred-year frequency storm runoff, as determined using the maximum
potential development of the drainage basin or watershed shall.
33
• Storm flows shall be collected and conveyed in a manner that avoids damage to
any improvement, building site or dwelling which may be constructed as part
of the project.
• Detention basins shall be sized to contain without freeboard a one-hundred-year
average recurrence interval runoff, unless it can be shown that a one- hundred-
year average recurrence interval runoff can be safely passed through the
detention basin without damage to the detention basin or any other property.
• Drainage capacity shall be provided that accounts for the full build-out of uses
anticipated with the drainage area.
The study shall be submitted to the Contra Costa County Public Works Department
(Flood Control District) for review and approval prior to finalizing individual
development plans. In addition, the Hydrology and Drainage Study shall be
reviewed by Airports Division staff to ensure any drainage basins proposed are
consistent with Federal Aviation Administration aviation obstruction standards for
avian attractants (e.g., requirement to drain ponded water within 48 hours of a major
storm event).
MM-HYD-2: Drainage Protection and Flood Control. For all areas of the project within the
Federal Emergency Management Agency (FEMA) 100-year floodplain (Special
Flood Hazard Area [SFHA]), Contra Costa County shall ensure that development
proposals are consistent with the requirements of the Contra Costa County
Floodplain Management Ordinance (Municipal Code Chapter 82-28), Contra Costa
County Flood Control Ordinance, and FEMA National Flood Insurance Program.
Development proposals in this area shall be submitted to the Contra Costa County
Public Works Department for review and approval, and all requirements imposed
by the department shall be satisfied. Such requirements may include floodproofing
measures (such as elevating structures above the base flood elevation and providing
the required freeboard). In the event development proposals involve encroachment
onto or undergrounding of Brushy Creek, a Clean Water Act Section 404 Permit
from the U.S. Army Corps of Engineers shall be obtained, per MM-BIO-6, and the
Contra Costa County Public Works Department shall be provided with drainage
studies and engineering reports sufficient to demonstrate that flood flows on Brushy
Creek would not be impeded or redirected. For all development planned within the
FEMA 100-year floodplain, subject to approval of the Contra Costa County Public
Works Department, the developer would be required to file a Conditional Letter of
Map Revision to process the change and shall obtain a FEMA modification of the
SFHA as shown on the Flood Insurance Rate Map.
34
Finding
The County Board of Supervisors finds that the above mitigation measures are feasible, will reduce
the potential hydrological impact (Impact 3.8-3) of the project to a less-than-significant level, and
is adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors
finds, that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines
Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project,
which avoid or substantially lessen the significant environmental effect as identified in the Final
EIR.
Rationale
Mitigation Measure HYD-1 would require the preparation of a drainage and hydrology study to
evaluate the difference between pre- and post-project storm flows, and establish drainage designs
necessary to mitigate the increase and adequately collect and convey flood flows. Implementation
of this mitigation measure would ensure that the capacity of the detention basin is adequate to
accommodate the project. Mitigation Measure HYD-2 would require compliance with existing
floodplain management regulations, studies to determine and demonstrate the capacity of the creek
corridor would be maintained, coordination with FEMA if the depth or boundaries of the
floodplain would be changed as a result, and review and approval by the County Public Works
Department. With implementation of the above discussed mitigation measures, the potential
impact would be reduced to less than significant.
Utilities
Result in the construction of new or expanded water, wastewater treatment, storm drainage,
electric power, natural gas, or telecommunications facilities, the construction or relocation of
which could cause significant environmental effects (Impact 3.14-1). The proposed project’s
utility requirements would exceed the capacity of existing water and wastewater facilities, which
would have a potentially significant impact.
Mitigation Measures
MM-UTIL-1: Prior to (1) the development of non-aviation uses, or (2) the expansion of aviation
uses that would increase water demand in excess of the current airport well system,
Contra Costa County (County) shall take one of the following actions:
a. Construct additional on-airport wells and water treatment facilities to support
the proposed development. The project Water Supply Assessment estimates
that up to four wells may be required to support buildout of the development
program. The County shall obtain a water supply permit from the State Water
Resource Control Board Division of Drinking Water, a well drilling permit
35
from Contra Costa County Environmental Health Division, and all other
applicable permits and approvals prior to development.
b. Obtain an off-site potable water supply from the Byron-Bethany Irrigation
District or the Town of Discovery Bay. The County shall not permit
development to proceed until the appropriate agreements or will-serve letters
have been obtained from the chosen supplier(s) and plans for construction of
necessary transmission lines have been approved by the County.
MM-UTIL-2: Prior to (1) the development of non-aviation uses or (2) the expansion of aviation
uses that involve additional human occupancy, Contra Costa County shall take one
of the following actions:
a. Expand the on-site septic system to accommodate forecasted development
wastewater flows. A permit from Contra Costa County Environmental Health
Division (CCCEHD) shall be obtained prior to development.
b. Construct an on-site package wastewater plant. The plant design, which
demonstrates adequate capacity for the development program, must be approved
by the CCCEHD. Prior to approval of development, Water Discharge Requirements
(WDR) must be approved by the Regional Water Quality Control Board.
c. Obtain service from the Town of Discovery Bay or Byron Sanitary District. The
County must confirm with the provider that there is adequate service capacity, and
obtain a will serve letter for airport development. Plans for construction of a sewer
transmission line to the off-site provider must be approved by all responsible
County agencies.
MM-HYD-1: See above.
Finding
The County Board of Supervisors finds that the above mitigation measures are feasible, will reduce
the potential project impact on utilities (Impact 3.14-1) to a less-than-significant level, and is
adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors finds,
that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines Section
15091(a)(1), changes or alterations have been required in, or incorporated into, the project, which
avoid or substantially lessen the significant environmental effect as identified in the Final EIR.
Rationale
Implementation of MM-UTIL-1 and MM-UTIL-2 would require construction of water and
wastewater facilities and limit project development until adequate capacity is available.
Implementation of MM-UTIL-1 and MM-UTIL-2, which require construction of additional on-
site and/or off-site infrastructure, may result in secondary impacts to the environment. These
36
secondary effects would be reduced to less than significant through implementation of MM-BIO-
1, MM-BIO-6, MM-CUL-1, MM-CUL-2, MM-CUL-3, and MM-NOI-1.
With implementation of the above discussed mitigation measures, the potential impact would be
reduced to less than significant.
Sufficient water supplies available to serve the project from existing entitlements and resources
(Impact 3.14-2). Currently, the well serving the airport property is insufficient to serve additional
project development. According to the Water Supply Assessment completed for the proposed
project, at the programmatic level of analysis, sufficient water supplies are available to serve its
water demand under normal and dry conditions, including existing and planned land uses, over the
20-year projection period. Because a definitive source of water has not yet been identified, and
additional facilities would be required to serve the project, this impact is potentially significant.
Mitigation Measure
MM-UTIL-1: see above.
Finding
The County Board of Supervisors finds that the above mitigation measures are feasible, will reduce
the potential impact on utilities (Impact 3.14-2) of the project to a less-than-significant level, and
is adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors
finds, that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines
Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project,
which avoid or substantially lessen the significant environmental effect as identified in the Final
EIR.
Rationale
As development under the proposed project proceeds, each of the potential supplies considered
would require additional feasibility analysis to determine the actual potential for project
implementation, and would require appropriate permits (e.g. new/expanded well construction) or
agreements (e.g., will-serve letter) from the off-site suppliers before any development requiring
potable water could be permitted. Additional infrastructure to serve the project site would be
constructed consistent with the water supply ultimately selected. This process is incorporated into
MM-UTIL-1. With implementation of the above discussed mitigation measure, the potential
impact would be reduced to less than significant.
Exceed the current wastewater treatment capacity to serve the project’s projected demand in
addition to the provider’s existing commitments (Impact 3.14-3). The project site is not currently
served by a wastewater treatment provider. The airport is currently served by a septic system which
does not have capacity for the proposed project.
37
Mitigation Measure
MM-UTIL-2: See above.
Finding
The County Board of Supervisors finds that the above mitigation measures are feasible, will reduce
the potential impact on utilities (Impact 3.14-3) of the project to a less-than-significant level, and
is adopted by the County Board of Supervisors. Accordingly, the County Board of Supervisors
finds, that pursuant to Public Resources Code Section 21081(a)(1), and the CEQA Guidelines
Section 15091(a)(1), changes or alterations have been required in, or incorporated into, the project,
which avoid or substantially lessen the significant environmental effect as identified in the Final
EIR.
Rationale
Through the implementation of MM-UTIL-2, and subsequently applicable biological, cultural
resource, and noise mitigation measures, the proposed project would not cause significant
environmental effects due to construction of new wastewater treatment facilities. With
implementation of the above discussed mitigation measure, the potential impact would be reduced
to less than significant.
Significant Unavoidable Impacts
The County finds that for the following impacts, changes or alterations have been required in, or
incorporated into, the project. However, specific economic, legal, social, technological, or other
considerations, make infeasible for the mitigation measures or alternatives identified in the EIR to
reduce the potential impacts to a less than significant level. For the reasons set forth in the
Statement of Overriding Considerations below, the County has determined that overriding
considerations, including economic, legal, social, technological, or other benefits, outweigh the
unavoidable adverse environmental effects associated with the project.
Air Quality
Conflict or obstruction with the implementation of the applicable air quality plan (Impact 3.2-
1). The project would lead to a substantial increase in operational emissions of NO x and PM 10,
and therefore potentially conflict with or obstruct implementation of the 2017 Clean Air Plan.
Mitigation Measure
MM-AQ-2: The project shall implement the following measures for all facilities in order to
reduce operational air pollutant emissions to the extent feasible. To the extent that
38
the measures below are addressed by MM-AQ-4 as part of any health risk
assessment that is prepared, the measures in MM-AQ-4 shall take precedence.
• Only haul trucks meeting model year 2010 engine emission standards shall be
used for the on-road transport of materials to and from the project site.
• Legible, durable, weather-proof signs shall be placed at truck access gates,
loading docks, and truck parking areas that identify applicable anti-idling
regulations. At a minimum, each sign shall include: 1) instructions for truck
drivers to shut off engines when not in use; 2) instructions for drivers of diesel
trucks to restrict idling to no more than 5 minutes once the vehicle is stopped,
the transmission is set to "neutral" or "park," and the parking brake is engaged;
and 3) telephone numbers of the building facilities manager and the CARB to
report violations.
• Prior to tenant occupancy, the facility operator shall provide documentation to
Contra Costa County demonstrating that occupants/tenants of the project site
have been provided documentation on funding opportunities, such as the Carl
Moyer Program, that provide incentives for using cleaner-than-required engines
and equipment.
• The minimum number of automobile electric vehicle (EV) charging stations
required by the California Code of Regulations Title 24 shall be provided. In
addition, the buildings shall include electrical infrastructure sufficiently sized
to accommodate the potential installation of additional auto and truck EV
charging stations in the future.
• Conduit shall be installed to tractor trailer parking areas in logical locations
determined by the facility operator during construction document plan check,
for the purpose of accommodating the future installation of EV truck charging
stations at such time this technology becomes commercially available.
Finding
The County Board of Supervisors finds that despite implementation of the feasible mitigation
measure, described above, the project would conflict with the 2017 Clean Air Plan and Impact 3.2-
1 would be significant and unavoidable.
Rationale
The significant impact is primarily caused by NO x and PM 10 emissions from mobile emissions,
particularly trucks to serve the proposed light industrial and warehouse uses. The County has
required all feasible emission controls within their jurisdiction. However, due to the need to
account for long haul trucking to serve future project development, no additional feasible
mitigation measures are available that would reduce this impact to less than significant.
39
Result in cumulatively considerable net increase of criteria pollutants for which the project
region is in nonattainment under an applicable Federal or State ambient air quality standard
(Impact 3.2-2). Project-related emissions of NO x and PM 10 , primarily from mobile sources, would
exceed the BAAQMD significance thresholds. As such, the project would have a potentially
significant impact in relation to regional operational emissions.
Mitigation Measures
MM-AQ-1: The project contractor would be required as conditions of approval to implement
the following best management practices that are required of all projects:
• All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas,
and unpaved access roads) shall be watered two times per day.
• All haul trucks transporting soil, sand, or other loose material off site shall be
covered.
• 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.
• All vehicle speeds on unpaved roads shall be limited to 15 mph.
• 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.
• 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, 13 CCR 2485). Clear signage
shall be provided for construction workers at all access points.
• All construction equipment shall be maintained and properly tuned in
accordance with manufacturer’s specifications. All equipment shall be checked
by a certified mechanic and determined to be running in proper condition prior
to operation.
• 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 BAAQMD’s phone number shall also be
visible to ensure compliance with applicable regulations.
MM-AQ-2: See above.
Finding
The County Board of Supervisors finds that despite implementation of the feasible mitigation
measures, described above, the project would lead to long-term impacts associated with a
40
cumulatively considerable net increase of criteria pollutants for which the project region is non-
attainment; therefore, the County Board of Supervisors finds that Impact 3.2-1 would be significant
and unavoidable.
Greenhouse Gas Emissions
Generation of greenhouse gas emissions, either directly or indirectly, that may have a significant
impact on the environment (Impact 3.6-1). Because the project would not meet the applicable
Climate Action Plan (CAP) consistency checklist criteria, it would be considered inconsistent with
the County’s CAP without mitigation. As such, the project would have a potentially significant
impact on climate change.
Mitigation Measures
MM-GHG-1: The individual development projects shall include the following transit-oriented
and alternative transportation development design features to reduce the use of
single-occupancy fossil fueled vehicles and vehicle miles traveled:
• Provide preferred parking for zero/low emission vehicles. Bicycle parking and
only the minimum amount of auto parking shall be provided to encourage
alternative forms of travel.
• Install conduits from the building(s) to the parking lot(s), to allow for
installation of EV charging stations for vehicles. The proportion of EV parking
spaces shall comply with the applicable CALGreen standards.
• The proposed project shall promote ridesharing programs through a
multifaceted approach, such as designating a certain percentage of parking
spaces for ridesharing vehicles; designating adequate passenger loading and
unloading and waiting areas for ridesharing vehicles; or providing a website or
message board for coordinating rides.
• The proposed project shall implement marketing strategies to reduce commute
trips. Information sharing and marketing are important components to
successful commute trip-reduction strategies. Implementing commute trip-
reduction strategies without a complementary marketing strategy would result
in lower vehicle miles traveled reductions. Marketing strategies may include:
new employee orientation of trip reduction and alternative mode options; event
promotions; or publications.
MM-GHG-2: The individual development projects shall include the following design features to
reduce the demand for energy use and greenhouse gas emissions:
• Obtain Leadership in Energy and Environmental Design (LEED) Certification
for building construction, where feasible.
41
• Provide the maximum amount of skylights to reduce electricity use associated
with interior lighting.
• All facility lighting shall meet or exceed the applicable Title 24 requirements.
• All installed appliances (e.g., washer/dryers, refrigerators, dishwashers) shall
be Energy Star rated or equivalent.
• Design proposed buildings with:
o Roof structure with additional load (defined as 1 to 2 pounds per square
foot) capacity to allow the future installation of solar panels without
retrofitting. The installation of solar panels would comply with the policy
and procedures set forth in the Interim Policy for FAA Review of Solar
Energy System Projects on Federally Obligated Airports (78 FR 63276).
o Installation of an above market sized electrical infrastructure system (larger
electrical room for future expansion, underground conduits (car, truck and
loading dock) for future electrical charging systems, as well as additional
conduits into the grid system for future expand-ability.
MM-GHG-3: The individual development projects shall incorporate the following design features
to conserve water:
• Install low flow plumbing fixtures, such as faucets, toilets, and showers.
• Utilize water efficient landscaping to reduce the usage of outdoor water on the
premises.
• Construct dual plumbing for both potable and recycled water for exterior
landscape irrigation, unless determined infeasible by Department of
Conservation and Development, Current Planning Division.
Finding
The County Board of Supervisors finds that despite implementation of the feasible mitigation
measures, described above, the project would not comply with the County CAP and the cumulative
GHG impact would remain; therefore, the County Board of Supervisors finds that Impact 3.6-1
would be significant and unavoidable.
Rationale
The primary source of project GHG emissions are mobile (truck trips associated with light
industrial and warehouse uses). As discussed in Air Quality, above, the County is limited in its
ability to enforce additional feasible mitigation measures to reduce emissions from long haul
trucking. The GHG significance finding is based on consistency with the County CAP. With
implementation of mitigation measures, the project would be consistent with the CAP checklist
items EE 1 (high efficiency appliances and insulation), RE 1 (solar ready), and LUT 2 (EV
42
charging stations). However, based on the rural location of Byron Airport, the project would not
comply with LUT 4 (located within one half-mile of a Bay Area Rapid Transit or Amtrak station
or within one quarter-mile of a bus station). Therefore, the project GHG impact cannot be reduced
to less than significant.
Conflict with an applicable plan, policy, or regulation for the purpose of reducing the emissions
of greenhouse gases (Impact 3.6-2). The project would not be consistent with the County’s CAP,
which is considered a qualified GHG reduction plan pursuant to CEQA, and established based on
the goal of AB 32 to reduce statewide emissions to 1990 levels by 2020. Therefore, the project
would also be considered inconsistent with implementation of any of the above-described GHG
reduction goals for 2030 or 2050. As such, the project would conflict with an applicable plan,
policy, or regulation adopted for the purpose of reducing the emissions of GHGs. This impact
would be potentially significant.
Mitigation Measures
MM-GHG-1: See above.
MM-GHG-2: See above.
MM-GHG-3: See above.
Finding
The County Board of Supervisors finds that despite implementation of the feasible mitigation
measures, described above, the project would not comply with the County CAP and the cumulative
GHG impact would remain; therefore, the County Board of Supervisors finds that Impact 3.6-2
would be significant and unavoidable.
Rationale
The primary source of project GHG emissions are mobile (truck trips associated with light
industrial and warehouse uses). As discussed in Air Quality, above, the County is limited in its
ability to enforce additional feasible mitigation measures to reduce emissions from long haul
trucking. The GHG significance finding is based on consistency with the County CAP. With
implementation of mitigation measures, the project would be consistent with the CAP checklist
items EE 1 (high efficiency appliances and insulation), RE 1 (solar ready), and LUT 2 (EV
charging stations). However, based on the rural location of Byron Airport, the project would not
comply with LUT 4 (located within one half-mile of a Bay Area Rapid Transit or Amtrak station
or within one quarter-mile of a bus station). Therefore, the project GHG impact cannot be reduced
to less than significant.
43
Noise
Generation of a substantial permanent increase in ambient noise levels in the vicinity of the
project area in excess of standards established in the local general (Impact 3.10-1). Project
operations would result in substantial traffic-related increases in outdoor ambient noise levels at
three residential locations. This impact would be potentially significant.
Finding
The County Board of Supervisors finds that Impact 3.10-1 would be significant and unavoidable,
and that there are no feasible mitigation measures to reduce this impact. Residential uses (sensitive
receptors) would be exposed to significant traffic noise due to the project.
Rationale
Project operations would result in substantial traffic-related increases in outdoor ambient noise
levels at three residential locations. Noise walls in the vicinity of the impacted sensitive receptors
could potentially reduce noise impacts to these receptors. However, such noise walls are infeasible
for the following reasons: inadequate public right-of-way that may require acquiring private
property to construct; access to the properties would require gaps in the noise walls that would
reduce their effectiveness; the noise walls would introduce potentially significant visual impacts
into the area which would particularly impact residents. Therefore, this impact cannot be reduced
to less than significant.
Transportation
The project would potentially conflict or be inconsistent with CEQA Guidelines Section
15064.3(b) (Impact 3.13-2). The project would have a potentially significant impact on VMT.
Because the Countywide VMT would increase with the proposed project relative to the total VMT
generated by the County under year 2040 conditions, the project’s cumulative impacts would be
considered significant.
Mitigation Measures
MM-TRAF-1: Project Site Design. The project shall provide site design features that facilitate
pedestrian amenities and promote accessibility for on-site pedestrian movement
and connectivity to various buildings or project components. As shown Table 3.13-
10, this measure would result in a range of reduction in VMT.
MM-TRAF-2: Bicycling Facilities. The project shall provide adequate bike parking, change, and
shower facilities on-site and improve accessibility for on-site bicycle movement as
well as connections to immediate proposed off-site bike lanes along Byron Hot
Springs Road and Holey Road. As shown in Table 3.13-10, this measure would
44
result in a 0.63% reduction in VMT. Low stress bikeway proposed along Byron
Highway can be made accessible to bicyclists from the project if bike routes can be
planned along Holey Road and Byron Hot Springs Road.
MM-TRAF-3: Access to Transit and Expansion of Transit Network. The project shall provide
access to transit and expand transit network. The project should work with Tri Delta
Transit to add transit service in the project vicinity and provide connections with
the cities of Antioch, Brentwood, Pittsburg and Oakley and other unincorporated
areas. As shown Table 3.13-10, this measure was assumed to result in a
conservative 0.1% reduction in VMT since there are no known transit service
improvement or expansion projects near the project site. However, once transit
coverage is increased, this VMT reduction could increase, however it would not
reduce the Project’s VMT to a less than significant level.
MM-TRAF-4: Ridesharing and Car-Sharing Programs for Employees. The project shall
provide/promote/subsidize ride-sharing programs to the employees by utilizing
approaches such as designating a certain percentage of parking spaces for ride
sharing vehicles, designating adequate passenger loading/unloading and waiting
areas for ride-sharing vehicles, and providing a website or message boards for
coordinating rides. Increasing the vehicle occupancy by utilizing ride sharing will
result in fewer cars driving the same trip, thereby decreasing the VMT. As shown
in Table 3.13-10, providing ridesharing and car-sharing programs to approximately
50% of the employees would result in a 2.5% and 0.4% reduction in VMT.
MM-TRAF-5: Employer-Sponsored Vanpool/Shuttle. The project shall provide an employer-
sponsored vanpool and shuttle for use by employees for commutes to work, and
bus/transit station. The vanpool and shuttle will be available to all employees;
however, the calculations conservatively assume the program would be offered
to/utilized by 50 percent of employees. As shown in Table 3.13-10, providing
employer-sponsored vanpool/shuttle to approximately 50% of the employees,
would result in a 6.7% reduction in VMT.
MM-TRAF-6: Encourage Telecommuting and Alternative Work Schedules for Employees.
According to CAPCOA, encouraging telecommuting and alternative work
schedules would reduce the number of commute trips, thereby reducing the
project’s VMT. Staggered start times, flexible schedules, or compressed work
weeks are examples of alternative work schedules. Because retail and
industrial/warehouse operations may require most of the employees to be on-site
24-hours per day, alternative work schedules may be feasible for a majority of the
employees. The project shall implement a 4-day/40-hour work schedule for
approximately 25% of the employees. As shown in Table 3.13-10, with 25%
45
employee participation in an alternate work schedule consisting of a 4-day/40- hour
work week, a VMT reduction of 3.75% would result.
MM-TRA-7: Implement Commute Trip Reduction Marketing. The project shall implement
marketing strategies to reduce commute trips. The marketing strategies would
include new employee orientation of trip reduction and alternative mode options,
event promotions and publications. Although the marketing would target all
employees, a conservative assumption of marketing to only 50 percent of the
employees was utilized in the calculation. As shown in Table 3.13-10,
implementing/promoting commute trip reduction marketing to approximately 50%
of the employees, would result in a 2.0% reduction in VMT.
MM-TRAF-8: Implement Subsidized or Discounted Transit Program for Employees. The
project shall provide subsidized or discounted daily or monthly public transit passes
to the employees. Although subsidized or discounted transit program would be
available to all employees, the VMT reduction calculation conservatively assumes
that the program would be available to and utilized by a maximum of 50% of
employees. As shown in Table 3.13-10, implementing subsidized or discounted
transit program to approximately 50% of the employees, would result in a 1.0%
reduction in VMT.
Finding
The County Board of Supervisors finds that despite implementation of the feasible mitigation
measures, described above, VMT impacts would remain; therefore, the County Board of
Supervisors finds that Impact 3.13-2 would be significant and unavoidable.
Rationale
Mitigation measures have been required that will encourage use of alternative transportation and
reduce single occupancy vehicle trips. However, VMT is primarily driven by existing land use
patterns. Introducing additional employment uses within a rural area will result in above average
(as compared to Bay Area) commute trip lengths. Due to the rural nature of the project vicinity,
transit is of limited effectiveness. The introduction of residential (mixed-use) development into the
project may reduce VMT but is not feasible, as the project site is an airport and therefore
incompatible with residential uses.
The project would substantially increase hazards due to a geometric design feature (e.g., sharp
curves, or dangerous intersections) or incompatible uses (e.g., farm equipment) (Impact 13.3-
3). The project has the potential to increase the volume of truck traffic on the roadway network to
serve warehousing and light industrial development and existing roads may be inadequate for
increased volumes of project-related traffic, including increased truck traffic.
46
Mitigation Measures
MM-TRAF-9: Prior to the completion of the first non-aviation development project that would
serve heavy trucks, the project proponent shall construct street improvements
related to the project site, as follows:
• Widen Byron Hot Springs Road to provide two 12-foot travel lanes and 5 to 8-
foot-wide shoulders (based on design ADT approved by Public Works
Department per County Standard Plan document and to include bike lanes and
sidewalk) from Byron Highway to Holey Road.
• Widen Holey Road to provide two 12-foot travel lanes and 5 to 8-foot-wide
shoulders (based on design ADT approved by Public Works Department per
County Standard Plan document and to include bike lanes and sidewalk) from
the Airport property line to Byron Highway.
• Ensure an adequate paved turn-radius at the intersection of Byron Hot Springs
Road and Armstrong Road to facilitate appropriate truck movement.
• Ensure an adequate paved turn-radius at the intersection of Byron Hot Springs
Road and Holey Road to facilitate appropriate truck movement.
Finding
The County Board of Supervisors finds that implementation of feasible mitigation measures would
reduce the potential impact of truck traffic on roadways which provide access to the project site.
However, the feasibility of improvements to improve vehicle queues at the Mountain House
Parkway/I-205 westbound ramps is uncertain. Impact 13.3-3 would be significant and
unavoidable.
Rationale
The proposed SR-239 TriLink project would likely reduce this impact to less than significant.
However, SR-239 Feasibility Study does not identify specific improvements, nor are specific
improvements planned or funded in the area. Therefore, this impact cannot be reduced to less than
significant.
VII. Alternatives
Public Resources Code section 21002 provides that “public agencies should not approve projects
as proposed if there are feasible alternatives or feasible mitigation measures available which would
substantially lessen the significant environmental effects of such projects[.]” The CEQA
Guidelines state that an EIR shall describe a reasonable range of alternatives that would avoid or
substantially lessen any significant effects of the project, but need not consider every conceivable
47
alternative. The CEQA Guidelines further state that “the discussion of alternatives shall focus on
alternatives to the project or its location which are capable of avoiding or substantially lessening
any significant effects of the project, even if these alternatives would impede to some degree the
attainment of the project objectives, or would be more costly” (CEQA Guidelines Section
15126.6[b]). Therefore, an EIR must describe a range of reasonable alternatives to the proposed
project (or to its location) that could feasibly attain most of the basic objectives of the project. The
feasibility of an alternative may be determined based on a variety of factors, including, but not
limited to, site suitability, economic viability, availability of infrastructure, general plan
consistency, other plans or regulatory limitations, jurisdictional boundaries, and site accessibility
and control (CEQA Guidelines Section 15126.6[f][1]).
Alternatives in an EIR must be potentially feasible (CEQA Guidelines, Section 15126.6[a]).
Agency decision makers ultimately decide what is “actually feasible.” (California Native Plant
Society v. City of Santa Cruz (2009) 177 Cal. App. 4th 957, 981 (CNPS).) Under CEQA, “feasible”
is defined as capable of being accomplished in a successful manner within a reasonable period of
time, taking into account economic, environmental, legal, social, and technological factors (CEQA
Guidelines Section 15364). The concept of “feasibility” also encompasses the question of whether
a particular alternative or mitigation measure promotes the underlying goals and objectives of a
project. (Sierra Club v. County of Napa (2004) 121 Cal.App.4th 1490, 1506-1509; CNPS, supra,
177 Cal. App. 4th at p. 1001; In re Bay-Delta Programmatic Environmental Impact Report
Coordinated Proceedings (2008) 43 Cal.4th 1143, 1165, 1166.) Moreover, “‘feasibility’ under
CEQA encompasses ‘desirability’ to the extent that desirability is based on a reasonable balancing
of the relevant economic, environmental, social, legal, and technological factors.” (City of Del Mar
v. City of San Diego (1982) 133 Cal.App.3d 410, 417.)
The EIR discussed and found the following alternative infeasible.
• Off-site alternative
The EIR analyzes three alternatives:
• No Project/Aviation Only
• Aviation Expansion
• Reduced Density
Alternative 1: No Project Alternative
Basis for Consideration
An EIR alternatives analysis must include the “no project” alternative to allow decision makers to
compare the impacts of approving the proposed project with the impacts of not approving the
proposed project (CEQA Guidelines Section 15126.6[e][1]). The no project discussion follows
48
one of two lines of analysis: (1) where the project includes a change to a land use plan or policy
(including zoning), what kind of development would reasonably be expected to occur under
existing plans and considering available infrastructure and services, or (2) if no development
would occur (the “no build” alternative), what would the effects be of the project site remaining in
its existing state compared to the circumstances if the proposed project were approved.
The approved Byron Airport Master Plan and Airport Layout Plan (Appendix D to the Airport
Master Plan) identify additional aviation development to support the anticipated growth in airport
operations. These include aircraft storage, cargo facilities, maintenance and repair, corporate
hangars and fixed-base operators, and expanded pilot and passenger facilities (Contra Costa
County 2005b, 2016). Aviation uses are consistent with the existing P-1 zoning and the ALUCP
for Byron Airport and were evaluated in the 1985 EIR prepared for the siting and development of
Byron Airport. Therefore, some level of development should be considered in the “no project”
scenario, consistent with the CEQA Guidelines. However, existing infrastructure is inadequate to
serve even the build-out of the current master planned aviation uses. It is, therefore, assumed that
aircraft storage could accommodate the additional 62 based aircraft. Supporting facilities would
be limited to 20,000 to 40,000 square feet—the estimated amount of development that could be
supported by the septic system based on existing use and capacity (Mead & Hunt 2013).
Description
It is assumed that based aircraft and operations would increase, consistent with the Airport Master
Plan. This alternative assumes that 167 aircraft would be based at the airport within 10 years
(compared to the current estimate of 105). Airport storage, including hangars and tie-downs, would
be constructed to accommodate additional aircraft. New structures would be limited to 20,000 to
40,000 square feet due to limitations in water, sewer, and stormwater infrastructure. Development
would occur in the aviation area, adjacent to existing airport facilities, as identified in Chapter 2,
Project Description. No development would occur in the non-aviation area east of the main
runway. Acquisition of the residence in the northeast corner of the project site would not occur.
Comparative Analysis of Environmental Effects
The No Project/Aviation Only Alternative would avoid all significant and unavoidable impacts
associated with the proposed project. This alternative would include some construction activities
and additional facilities, so certain construction-related impacts would be potentially significant,
but these would be mitigated through implementation of feasible mitigation measures identified
for that project. These measures would be for impacts to biology, cultural resources, geology,
hazards, and hydrology.
49
Findings
The No Project/Aviation Only Alternative would, for the most part, achieve the aviation-related
objectives of the project, as follows:
• Develop airport facilities to support the types of development envisioned in the Airport
Master Plan and subsequent airport planning efforts.
• Protect current and future airport operations from incompatible land uses.
However, this alternative would not achieve the objectives related to economic development or
financial self-sufficiency. The airport would continue to operate at a deficit under this alternative.
Therefore, the County finds this alternative to be infeasible.
Alternative 2: Aviation Expansion Alternative
Basis for Consideration
The Aviation Expansion Alternative is similar to the No Project/Aviation Only Alternative (see
above) but assumes that additional infrastructure would be constructed for full build-out of the
aviation area. This alternative would reduce significant impacts related to transportation and related
health risks, greenhouse gas emissions, and noise. Since traffic generation from new development
east of the main runway (including vendors, employees, and visitors) would not occur, this
alternative is expected to substantially reduce those impacts.
Description
It is assumed that based aircraft and operations would increase consistent with the Airport Master
Plan. A total of 11.8 acres would be dedicated to future airport storage (including hangars and tie-
downs). Up to 154,000 square feet of aviation-related buildings would be constructed within an
area of 11.8 acres. No development would occur in the airport-related area east of the main runway.
Acquisition of the residence in the northeast corner of the project site would not occur.
Comparative Analysis of Environmental Effects
Since no development would occur east of the main runway, the three houses near the airport
would not be affected, avoiding impacts related to health risk and noise (due to increased traffic).
Transportation impacts would be substantially reduced (because of reduced number of truck
traffic, vendors, employees, and visitors). The potentially significant (but mitigatable) aesthetics
impact of large structures east of the airport would also be avoided. Associated greenhouse gas
emissions would also be substantially reduced. Construction impacts related to expansion of the
aviation uses, including impacts to biology, cultural resources, geology, hazards, hydrology, and
public utilities, would still occur, but would be mitigated by feasible mitigation measures, as
described throughout this EIR.
50
Findings
The Aviation Expansion Alternative would achieve the aviation-related objectives of the project,
as follows:
• Develop airport facilities to support the types of development envisioned in the Airport
Master Plan and subsequent airport planning efforts.
• Protect current and future airport operations from incompatible land uses.
However, this alternative would not achieve the objectives related to economic development or
financial self-sufficiency. The airport would continue to operate at a deficit under this alternative.
Therefore, the County finds this alternative to be infeasible.
Alternative 3: Reduced Intensity
Basis for Consideration
The Reduced Intensity Alternative is based on the initial development scenario for the proposed
project. This scenario did not include an update of the ALUCP, so the intensity of proposed
development was constrained. Since several of the significant project impacts are related to the
intensity of development, particularly in proximity to residential uses east of the airport, this reduced-
intensity alternative provides a useful comparison. This alternative would use the same development
footprint as the proposed project, but would not include acquisition of the 11.7-acre parcel. Due to the
reduced amount of acreage, and the reduction in allowable floor area ratio (FAR), office and
commercial uses would be considered infeasible in this development scenario, and the available non-
aviation development area would consist of logistics/warehouse/distribution and light/industry
business park uses.
Description
Based aircraft and operations would increase consistent with the Airport Master Plan because
aviation expansion would still occur on the 23.5 acres designated for aviation uses. The
development footprint would be similar to the proposed project, but the intensity would be
reduced. The floor-to-area ratio of logistics/warehouse/distribution would be reduced to 0.25 (from
0.30 for the proposed project). Office and commercial development would be eliminated under
this alternative, and the potential acreage for those uses would be used for
logistics/warehouse/distribution and light industry/business park. The 11.7-acre parcel adjacent to
the airport-related development would not be acquired.
Total building area would be reduced to 723,000 square feet, as opposed to the proposed project
amount of 941,000 square feet (see Chapter 4 of the Final EIR for complete description). Total
51
employees and visitors would not exceed 636 at any given time, as opposed to 1,528 for the
proposed project.
Comparative Analysis of Environmental Effects
Transportation impacts would be reduced by eliminating commercial and office uses. However,
truck traffic would be similar to the proposed project, since this alternative could result in 484,000
square feet of warehouse/light industrial uses compared to 487,000 for the proposed project. Traffic
impacts would still likely be significant but reduced, with a corresponding decrease in the amount of
mitigation required. Associated greenhouse gas emissions would also be reduced, but likely not to a
less-than-significant level. Since warehousing and light industrial uses would still be constructed
east of the airport, impacts related to health risk would still potentially occur, but could be mitigated.
The potentially significant (but mitigatable) aesthetics impact of large structures east of the airport
would also be avoided, since warehousing would be less dense and farther from existing homes.
Construction impacts related to expansion of the aviation uses, including impacts to biology, cultural
resources, geology, hazards, hydrology, and public utilities, would still occur, but would be mitigated
by feasible mitigation measures described throughout this EIR.
Findings
The Reduced Intensity Alternative would achieve the aviation-related objectives of the
project, as follows:
• Develop airport facilities to support the types of development envisioned in the Airport
Master Plan and subsequent airport planning efforts.
• Protect current and future airport operations from incompatible land uses.
This alternative would not fully achieve the economic objectives:
• Achieve economic self-sufficiency of the airport through the development of airport-
related land uses.
• Provide a streamlined planning framework for development consistent with the General
Plan and the ALUCP.
This alternative would reduce but not fully mitigate the significant and unavoidable impacts of the
project. In addition, the economic development and fiscal objectives of the County would not be
fully realized. For these reasons, the County finds this alternative to be infeasible.
VIII. Statement of Overriding Considerations
As set forth in the preceding sections, approving the project will result in some significant adverse
environmental effects that cannot be avoided even with the adoption of all feasible mitigation
measures. There are no feasible alternatives to the project that would fully mitigate or substantially
52
lessen the impacts. Despite these effects, the County, in accordance with CEQA Guidelines section
15093, chooses to approve the project because, in its judgment, the following economic, social,
and other benefits that the project will produce will render the significant effects acceptable.
1. The Airport Land Use Compatibility Plan (ALUCP) for Byron Airport is inconsistent with
both the current version of the California Airport Land Use Planning Handbook (2011)
and the ALUCP for Buchanan Field Airport. Updating the ALUCP would provide for
consistent implementation of development standards throughout the County. This is a
benefit both to private landowners and to County planning.
2. The project would provide economic development opportunities in east Contra Costa
County. The east County has traditionally had a much higher unemployment rate relative
to the County as a whole. For example, in September 2021, the County unemployment rate
was 5.5%, while the unemployment rate in the Byron Census Designated Place was 11%
(California Economic Development Department, 2021).
3. The project would provide for economic self-sufficiency for Byron Airport. The Airport
currently operates a loss. This shortfall is compensated by revenues at Buchanan Field
Airport. The proposed project would eliminate a budget deficit that would improve the
fiscal health of the County.
IX. Conclusion
The County Board of Supervisors has balanced these benefits and considerations against the
significant unavoidable environmental effects of the project. After balancing the environmental
costs against the project’s benefits, the Board concludes that the benefits outweigh the adverse
environmental impacts. The Board finds that the project’s benefits outlined above, and each of
them individually, override the significant unavoidable environmental costs associated with the
project.
FINDINGS AND CONDITIONS OF APPROVAL FOR COUNTY FILE #GP12-0003, DP14-3008 &
RZ21-3262; CONTRA COSTA COUNTY (APPLICANT & OWNER)
PROJECT FINDINGS
A. General Plan Amendment
1. Required Finding: Adoption of the proposed General Plan Amendment will not
violate the County Urban Limit Line.
Project Finding: The portion of the project site where development may occur is
fully located inside the County’s Urban Limit Line (ULL), and therefore may be
developed with “urban” or “non-urban” uses, as defined in the 2005-2020 Contra
Costa County General Plan. The Public and Semi-Public (PS) land use designation
for Byron Airport, including the General Plan Amendment to the 11.7-acre parcel,
is non-urban. All proposed land uses, both aviation-related and non-aviation-
related, will be located on land designated PS and within the ULL.
2. Required Finding: Adoption of the proposed General Plan Amendment is
consistent with the 65/35 Land Preservation Standard.
Project Finding: Adoption of the proposed General Plan Amendment (GPA) will
not cause a violation of the 65/35 Land Preservation Standard (the “65/35
Standard”), originally approved by County voters through adoption of Measure C-
1990 and reaffirmed through adoption of Measure L-2006. Under the 65/35
Standard, no more than 35 percent of the land in the County may be developed
with urban uses and at least 65 percent of the land must be preserved for non-
urban uses such as agriculture, open space, parks, wetlands, and public facilities.
The existing land use designations for the subject site, Public and Semi-Public (PS)
and Agricultural Lands (AL), are non-urban land use designation. Changing the land
use designation for 11.7 acres from AL to PS does not change the percentage of
land devoted to urban and non-urban uses.
3. Required Finding: The proposed General Plan Amendment is consistent with the
Contra Costa Transportation Authority Growth Management Program.
Project Finding: The project complies with the objectives and requirements of
Measure J-2004, the Contra Costa Transit Authority (CCTA) Growth Management
Program (GMP), and related CCTA resolutions. The CCTA GMP Implementation
Guide (2021) sets forth procedures for local agency consultation and evaluation of
impacts of proposed General Plan Amendments. The Byron Airport Development
Program EIR was evaluated according to the CCTA GMP GPA Review Process and
Technical Procedures for evaluating transportation impacts. Therefore, the project
complies with the objectives and requirements of Measure J-2004, the Contra Costa
Growth Management Program, and related CCTA resolutions.
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 2 of 36
4. Required Finding: Following adoption of the proposed General Plan Amendment,
the General Plan will remain internally consistent, as required under Government
Code Section 65300.5.
Project Finding: The General Plan comprises an integrated, internally consistent,
and compatible statement of policies governing development in the
unincorporated areas. Although the proposed GPA involves revising policies to
expand the allowed uses at Byron Airport and redesignating the 11.7-acre parcel
to PS to be included as part of the Byron Airport Development Program, the
expanded aviation and non-aviation uses are consistent with the PS designation of
the land inside the ULL and will support the General Plan goal of operating two
airports in the County, among other goals and policies. The two amended policies
will also not cause inconsistencies, as they are very specific to Byron Airport and
do not affect County policy unrelated to that facility. Therefore, adoption of the
proposed GPA will not cause the General Plan to become internally inconsistent.
5. Required Finding: Adoption of the proposed General Plan Amendment is in the
public interest, as required under Government Code Section 65358(a).
Project Finding: Pursuant to Government Code Section 65358(a), the General Plan
may be amended if such amendment is deemed to be “in the public interest.” The
proposed project would help implement General Plan Goal 5-Q, to encourage the
development and operation of two general purpose public airports in the county,
by supporting the financial self-sufficiency of Byron Airport. The project will
support this through economic development around the airport, which will also
serve to improve the severe jobs/housing imbalance in East County by adding
high-quality employment opportunities at the airport.
6. Required Finding: Adoption of the proposed General Plan Amendment would not
exceed the limit on such amendments specified under Government Code Section
65358(b).
Project Finding: Pursuant to Government Code Section 65358(b), no mandatory
element of the General Plan may be amended more than four times per calendar
year. The proposed GPA affects the Land Use and Transportation and Circulation
element, both mandatory elements, and is the third consolidated amendment for
2022.
B. Growth Management Performance Standards
1. Traffic: Implementation Measure 4-c under the Growth Management Program
(GMP) of the County’s General Plan requires a traffic impact analysis be conducted
for any project that is estimated to generate 100 or more AM or PM peak-hour
trips. The project involves a County-initiated General Plan Amendment (GPA),
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 3 of 36
Development Plan Modification (DPM), Rezone, and Airport Land Use
Compatibility Plan (ALUCP) Amendment for the Byron Airport to expand the range
of uses allowed on the airport property. As part of the EIR, a Traffic Impact Analysis
(TIA) was prepared. The Draft EIR identified several impacts and mitigation measure
based primarily on the results of the TIA. The project has the potential to increase
the volume of truck traffic on the roadway network to serve warehousing and light
industrial development. Although regional roadways, such as Byron Highway and
SR-4, already safely handle significant volumes of truck traffic, the rural roads
providing access to Byron Airport may not support the increase in truck traffic.
Existing traffic volumes can be handled on these roads, but they may be inadequate
for increased volumes of project-related traffic, including increased truck traffic. As
such, the Draft EIR identified this as a potentially significant impact. Therefore, the
project proponent would construct the street improvements along Armstrong
Road, Byron Hot Springs Road, and Holey Road described in Draft EIR mitigation
measure TRAF-9 to reduce access impacts related to heavy truck traffic.
2. Water: The project site is not connected to public water services; instead, the
project site relies on existing on-site water wells and a 4,000-gallon on-site water
tank for its domestic, non-potable water. Bottled water is used for drinking water.
Currently, the well serving the airport property is insufficient to serve additional
project development. According to the Water Supply Assessment completed for
the proposed project, at the programmatic level of analysis, sufficient water
supplies are available to serve its water demand under normal and dry conditions,
including existing and planned land uses, over the 20-year projection period (Draft
EIR Appendix I). This would be accomplished through the use of one or more of
the proposed options, including on-site expansion of wells for extraction and
treatment of additional groundwater, importation of treated water from Discovery
Bay Community Services District (CSD), or importation and on-site treatment of
additional water from Byron-Bethany Irrigation District (BBID). However, as
development under the proposed project proceeds, each of the potential supplies
considered would require additional feasibility analysis to determine the actual
potential for project implementation, and would require appropriate agreements
(e.g., will-serve letter) from the off-site suppliers before any development requiring
potable water could be permitted. This process is incorporated into MM-UTIL-1.
Connection to either Discovery Bay CSD or BBID may also conflict with the County’s
Urban Limit Line policy, so on-site expansion of groundwater systems would be
the ideal method.
3. Sanitary Sewer: The project site is not connected to public sewer services; instead,
the airport relies on an existing on-site septic system and leach field for its sanitary
service. The Byron Airport Infrastructure Study considered two potential wastewater
generation rates (Mead & Hunt 2013). The Infrastructure Study compared two
generation rates for bulk warehousing and industrial development: the Central
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 4 of 36
Contra Costa Sanitary District’s Collection System Master Plan rate of 1,000 gpd per
gross acre, and the City of Oakland rate of 25 gpd per 1,000 square feet of building
square footage. The Infrastructure Study used the Oakland rate of 25 gpd per 1,000
square feet, resulting in an estimated 96,000 gpd build-out demand. The
development assumptions in the Infrastructure Study are greater than for the
proposed project (146.9 acres and 3,840,000 square feet of building space,
compared to 70 acres and 941,000 square feet of building space for the proposed
project). Applying the Oakland rate to the proposed project would result in an
estimated wastewater flow of 23,525 gpd. However, the Town of Discovery Bay,
which contains the nearest wastewater treatment plant, uses a wastewater
generation rate of 2,000 gpd per acre of industrial development and 1,600 gpd per
acre of commercial development. Using these flow rates, wastewater flow would be
89,920 gpd for non-aviation uses. Therefore, the project’s wastewater requirements
would exceed existing infrastructure.
MM-UTIL-2 requires implementation of a wastewater system, per the
recommendations of the Byron Airport Infrastructure Study (Mead & Hunt 2013),
which studied several options for expansion of the on-site sewer system. The
options include requiring each new use or development to provide for its own
wastewater disposal, in effect distributing wastewater treatment to smaller leach
fields throughout the site, or development of centralized treatment though use of
an on-site package wastewater treatment plant and establishment of collection
pipelines. For an on-site treatment plant, effluent disposal may be accomplished
through landscape irrigation if the effluent is treated to a level to meet Title 22 CCR
standards. A third option is connection to an existing sewer system: either the
Discovery Bay Community Services District or the Byron Sanitary District.
Connection to Discovery Bay would involve off-site construction of a force main
and likely modifications to the existing sewage lift station (or a new lift station).
Connection to Byron Sanitary District would likely require an expansion of Byron
Sanitary District’s wastewater treatment facility. Connection to either Discovery Bay
or Byron Sanitary District may also conflict with the County’s Urban Limit Line
policy, so on-site expansion of septic systems and leach fields would be the ideal
method.
4. Fire Protection: The nearest fire station to the project site is Station 59, which is
located approximately 8 miles to the north. Project elements would comply with
federal, state, and local requirements regarding fire protection, including the California
Building Code and California Fire Code, and California Government Code Section
51182 and Public Resources Code Section 4291, which would reduce fire hazards to
buildings and structures. Byron Airport maintains its own water system for fire
suppression, which would be expanded prior to any airport-related industrial or
commercial development.
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 5 of 36
5. Public Protection: The County Sheriff’s Office provides law enforcement services
within the county. The nearest County Sheriff’s station to the project site is Delta
Station, located approximately 12.2 miles northwest in Oakley. Although the
project would expand aviation and non-aviation uses at the site, which would
increase the number of people on the site, the project would not include residential
uses that would cause substantial population growth in the county. Furthermore,
the project would primarily employ people residing in the region and would not
substantially increase demand for housing or result in population growth (see
Section 3.11 of the Draft EIR). Population is used by the Sheriff’s Office to determine
the need for new or expanded facilities (General Plan Policy 7-57). The project is
not expected to increase demand for police protection services such that new or
expanded facilities would be required.
6. Parks and Recreation: The County Public Works Department provides park and
recreational services to the unincorporated County, including the project site. The
project would not involve development of residential uses or result in a direct or
indirect population growth that would, in turn, increase demand on regional parks
and open spaces. Therefore, impacts related to parks and recreational resources
would be less than significant.
7. Flood Control and Drainage: Flood zones identified on Federal Emergency
Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs) are identified as
a Special Flood Hazard Area (SFHA). An SFHA is defined as the area that will be
inundated by the flood event having a 1% chance of being equaled or exceeded in
any given year. The 1%-annual-chance flood is also referred to as the base flood
or 100-year flood. . FEMA has mapped SFHAs on the project site, which are labeled
flood zones A, AE, and B. The flood zone widens significantly along Brushy Creek
in an area located west of Runway 12-30 and west of Falcon Way, and spreads over
low-lying areas between the two runways and south of Runway 5-23. The flood
zone crosses Falcon Way near its intersection with Armstrong Road and crosses
the northeastern end of Runway 5-23. Review of the flood zone shows that it is
largely confined to areas of the project site that would be designated as habitat
management or low intensity use. However, the flood zone intersects an area
designated for airport-related uses just south of Armstrong Road, northwest of
Runway 12-30. There is also a regulatory floodway along Brushy Creek, which
intersects the northern edge of the proposed development area for airport-related
uses. In addition, the 100-year flood hazard area terminates at the airport’s 15-acre
detention basin located southeast of Runway 12-30 and east of Runway 5-23. East
of the detention basin, a 500-year hazard area (also referred to as a 0.2%-annual-
chance flood hazard) is mapped by FEMA.
Prior to and at full build-out, the project would involve substantial increases in the
amount of impervious surfaces, which has the potential to substantially increase
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 6 of 36
the rate and volume of storm runoff during peak storm events without adequate
measures to detain, retain, or slow the increased flows. The distribution and extent
of impervious surfaces to be constructed is not known precisely at this time but
would occur in a 70-acre area planned for non-aviation uses (46.6 acres) and the
aviation area (23.5 acres). At full build-out, the total building footprint for all new
uses is anticipated to be approximately 914,000 square feet (or 21 acres). Though
some of this area may consist of landscaping or water quality control BMPs (e.g.,
swales, gravel, or pervious pavement), most of the building footprint is expected
to consist of impervious surfaces, given the anticipated uses (e.g., typically 80% to
90% of the building footprint). The following subsections examine the impacts that
altered flow regimes would have on erosion or siltation, on- or off-site flooding,
the capacity of existing or planned stormwater drainage systems, and the
impedance or redirection of flood flows. Due to the increases in impervious
surfaces, could result in increases in runoff to the on-site detention basin and to
Brushy Creek, which is a natural waterway. If not properly controlled, such increases
in runoff could exacerbate on- or off-site flooding that already occurs as part of
the existing conditions.
As discussed in Draft EIR Section 3.8.2, a drainage permit would be required to
comply with Division 914 of the County Ordinance Code. Among other things, the
ordinance prohibits the impairment or impedance of the natural flow of
stormwaters; direct physical impacts to watercourses (e.g., through grading,
excavation, filling, and/or development); or the construction, alteration or repair of
a drainage structure, facility, or channel without first obtaining a permit from the
public works department. Division 914 establishes on-site and off-site collect and
convey requirements that must be met before development approvals are granted.
Applicants are required to substantiate that both on-site and off-site drainage
facilities have adequate capacity to convey specified design storm events, that the
capacity and stability of natural watercourses are adequately protected, and that
environmentally sensitive flow velocity attenuation techniques approved by the
Public Works Department are implemented.
C. Rezone Findings
1. Required Finding: The change proposed will substantially comply with the
General Plan.
Project Finding: The proposed project is located primarily within the PS
designation, in which public airports are a compatible use. The existing aviation
facilities and the master-planned development areas are designated as PS. The
proposed project also includes the redesignation of the 11.7-acre parcel from AL
to PS, which, after its redesignation, would result in the entire project being located
within the PS designation. The remainder of the airport property is designated OS,
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 7 of 36
consistent with the habitat management use for the non-developable airport
property. The portion of the project site where development may occur is fully
located inside the County’s Urban Limit Line (ULL). All proposed land uses, both
aviation-related and non-aviation-related, will be located on land designated PS
and within the ULL.
The proposed GPA involves revising policies to expand the allowed uses at Byron
Airport and redesignate the 11.7-acre parcel to PS to be included as part of the
Byron Airport Development Program. The expanded aviation and non-aviation
uses allowed under the P-1 zoning are consistent with the PS designation of the
land inside the ULL and will support the General Plan goal of operating two airports
in the county, among other goals and policies.
2. Required Finding: The uses authorized or proposed in the land use district are
compatible within the district and with uses authorized in adjacent districts.
Project Finding: The airport property is currently zoned P-1. The P-1 zoning is
intended to allow diversification in the relationship of various uses, buildings,
structures, lot sizes, and open space areas while ensuring compliance with the
General Plan and the intent of the County Code in requiring adequate standards
necessary to satisfy the requirements of public health, safety, and general welfare.
Currently, the Byron Airport P-1 zoning only allows aviation-related uses,
agriculture, and open space. The amended Planned Unit District will identify four
separate development areas: Aviation, Airport Related, Low-Intensity Use, and
Habitat Management (see Attachment 7, Proposed Site Plan). The most important
change would be to the airport-related uses, which would allow non-residential
development that is compatible with the ALUCP for Byron Airport. These uses
would include light industry, warehousing and logistics, commercial, and low-
intensity office. In addition, the 11.7-acre parcel to be acquired by the County
would be rezoned from A-3 to P-1 in order to be included as part of the Byron
Airport Development Program.
Byron Airport is surrounded by low-intensity uses. Byron Hot Springs, a now
abandoned resort and former World War II prisoner-of-war camp, is located north
of the airport, agricultural and rural residential uses border the east and west sides
of the airport property, and agricultural lands and property owned by East Bay
Regional Park District are located to the south. The airport is the most developed
property in the area. The proposed higher-intensity land uses are commonly
located adjacent to airports and are compatible with the existing airport uses.
While the surrounding properties have not been developed with higher intensity
uses, the agricultural zoning allows uses of an industrial nature, such as packing
plants, granaries, and warehouses, by right. The proposed uses are therefore
compatible with the adjacent zoning.
CPC – March 9, 2022

Findings & COAs Page 8 of 36
3. Required Finding: Community need has been demonstrated for the use proposed,
but this does not require demonstration of future financial success.
Project Finding: Byon Airport currently operates at an annual net deficit. Allowing
for more land uses and increased intensities within the Byron Airport planning area
will increase revenue for the airport and County.
Allowing for more land uses also helps improve the Jobs/Housing balance in East
Contra Costa County. According to General Plan Table 2-4, the projected
jobs/hosing ratio for East County in 2020 was 0.45 jobs per resident. This low ratio
results in a large population of East County residents commuting out of the county
for work, rather than commuting locally. This mass exodus from East County
communities creates significant traffic along local roads and highways, among
other negative impacts to the environment and quality of life. Providing new, high
quality economic opportunities for residents in East County would help make a
dent in the jobs/housing ratio.
D. Findings of Approval of P-1 Zoning District and Final Development Plan
1. Required Finding: The applicant intends to start construction within two and one-
half years from the effective date of the zoning change and plan approval.
Project Finding: The applicant has indicated that they intend to commence
construction within 2 ½ years of the effective date of the zoning change and plan
approval.
2. Required Finding: The proposed planned unit development is consistent with the
County General Plan.
Project Finding: The County General Plan designates the existing aviation facilities
and the master-planned development areas as Public/Semi-Public (PS). The
remainder of the airport property is designated as Open Space (consistent with the
habitat management use for the non-developable airport property) (Contra Costa
County 2017). The General Plan designation for the existing airport property will
not change. The 11.7-acre acquisition parcel would be redesignated from
Agricultural Lands (AL) to PS. General Plan Policy 5-66 states, “Establishment of
commercial, industrial or residential development around the planned airport shall not
be allowed” (Contra Costa County 2005b). This policy would be amended to specify
that commercial or industrial development would be allowed on airport property if it
is consistent with the ALUCP and the Airport Master Plan for Byron Airport. Policy 5-
77 would be updated to reflect the new compatibility zone designations (Zone B-
1 would become Safety Zone 2) and the additional uses at the airport that may be
found compatible under the updated ALUCP for Byron Airport.
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 9 of 36
The project would help implement General Plan Goal 5-Q, to encourage the
development and operation of two general purpose public airports in the county,
by providing for the economic development and financial self-sufficiency of Byron
Airport. The General Plan policies regarding the airport would be amended to
clarify that compatible non-aviation uses would be allowed on airport property.
General Plan Policy 5-66 would be amended to specify that commercial or
industrial development would be allowed on-airport if it is consistent with the
ALUCP and the Byron Airport Master Plan. Not only would increasing the economic
viability of Byron Airport help it operate in a financially beneficial way to the
County, but it would also help support the Jobs/Housing balance in East Contra
Costa County. According to General Plan Table 2-4, the projected jobs/hosing ratio
for East County in 2020 was 0.45 jobs per resident. This low ratio results in a large
population of East County residents commuting westward for work, rather than
commuting locally or eastward. This mass exodus from East County communities
creates significant traffic along local roads and highways, among other negative
impacts to the environment and quality of life. Providing new, high quality
economic opportunities for residents in East County would help make a dent in the
jobs/housing ratio, especially with the rapidly increasing population growth in East
County. With the included amendments, the proposed project would be consistent
with the County General Plan.
3. Required Finding: In the case of residential development, it will constitute a
residential environment of sustained desirability and stability and will be in
harmony with the character of the surrounding neighborhood and community.
Project Finding: The project does not include any residential development.
4. Required Finding: The development of a harmonious integrated plan justifies
exceptions from the normal application of this code.
Project Finding: The airport property is currently zoned Planned Unit District (P-
1). The P-1 zoning is intended to allow diversification in the relationship of various
uses, buildings, structures, lot sizes, and open space areas while ensuring
substantial compliance with the General Plan and the intent of the County Code in
requiring adequate standards necessary to satisfy the requirements of public
health, safety, and general welfare. Currently, the Byron Airport P-1 zoning only
allows aviation-related uses, agriculture, and open space. The amended Planned
Unit District will identify four separate development areas: Aviation, Airport
Related, Low-Intensity Use, and Habitat Management. The most important change
would be to the airport-related uses, which would allow non-residential
development that is compatible with the ALUCP for Byron Airport. These uses
would include light industry, warehousing and logistics, commercial, and low-
intensity office.

The P-1 district for Byron Airport would also be revised to identify the land use
categories used in the ALUCP: aviation, non-aviation, low intensity, and habitat
management. Additional land uses that could be allowed within the aviation and
non-aviation areas would be identified, as discussed in Section 2.6, Proposed Land
Uses and Zoning, of the Draft EIR. The P-1 modification would specify that all
proposed land uses must be reviewed by County staff for consistency with the
current ALUCP. The zoning would also implement the ALUCP and General Plan
standards for compatible land use, including height restrictions.

b. Legible, durable, weather-proof signs shall be placed at truck access gates, loading
docks, and truck parking areas that identify applicable anti-idling regulations. At a
minimum, each sign shall include: 1) instructions for truck drivers to shut off
engines when not in use; 2) instructions for drivers of diesel trucks to restrict idling
to no more than 5 minutes once the vehicle is stopped, the transmission is set to
"neutral" or "park," and the parking brake is engaged; and 3) telephone numbers
of the building facilities manager and the CARB to report violations.
c. Prior to tenant occupancy, the facility operator shall provide documentation to
Contra Costa County demonstrating that occupants/tenants of the project site
have been provided documentation on funding opportunities, such as the Carl
Moyer Program, that provide incentives for using cleaner-than-required engines
and equipment.
d. The minimum number of automobile electric vehicle (EV) charging stations
required by the California Code of Regulations Title 24 shall be provided. In
addition, the buildings shall include electrical infrastructure sufficiently sized to
accommodate the potential installation of additional auto and truck EV charging
stations in the future.
e. Conduit shall be installed to tractor trailer parking areas in logical locations
determined by the facility operator during construction document plan check, for
the purpose of accommodating the future installation of EV truck charging stations
at such time this technology becomes commercially available.
10. For non-aviation facilities with construction proposed within 1,000 feet of off-site
residential receptors, a construction health risk assessment shall be prepared to assess
exposure of existing sensitive receptors to toxic air contaminants (TACs) during project
construction. If the health risk assessment determines that cancer and non-cancer impacts
would be less than significant, no additional measures are needed. Alternatively, the results
of the health risk assessment may necessitate implementation of TAC exposure reduction
strategies in order to reduce potential risk to less-than-significant levels, which could
include, but are not limited to, the following (MM-AQ-3):
a. Portable equipment used during construction shall be powered by electricity from
the grid instead of diesel-powered generators, to the maximum amount feasible.
b. Equip heavy-duty diesel-powered construction equipment with Tier 4 Interim or
better diesel engines, except where Tier 4 Interim or better engines are not

c. All conditions of approval/mitigations shall be placed on construction drawings
and part of any construction contract. Physical copies of the plans shall be available
at the on-site job trailer.
11. For non-aviation uses, a health risk assessment of long-term operations shall be prepared
if the proposed facility is within 1,000 feet of off-site residential receptors and would result
in any of the following (MM-AQ-4):
a. Accommodate more than 100 trucks per day, or
b. Accommodate more than 40 trucks with operating TRUs per day, or
c. Where TRU operations exceed 300 hours per week.
Results of the health risk assessment may necessitate implementation of TAC exposure
reduction strategies in order to reduce potential risk to less-than-significant levels, which
could include, but are not limited to, the following:
d. Idling of diesel equipment of any type shall be strictly prohibited at the premises.
The property owner/tenant/lessee shall inform all business partners, visitors, etc.,
of the Zero-Idling Rule in effect for the subject property and area streets. Highly
visible signs prohibiting idling shall be posted at each entrance and exist. Violators
of this zero-idling rule are subject to fines and or criminal charges.
e. Within 90 days of occupying the space, the facility operator shall submit to the
Airports Division and the Department of Conservation and Development (DCD) the
first of an annual inventory of all equipment that generates criteria pollutant, TACs,
and GHG emissions operated at the subject location throughout the life of the
project up to year 2035. The equipment inventory shall include the year, make, and
model of the equipment that was used in the previous year, including annual hours
of operation for each piece of equipment, including but not limited to heavy-duty
drayage and non-drayage trucks, yard equipment, bulk material handling
equipment (forklifts, etc.), and any other type of material handling equipment. The
purpose of the inventory is to track emissions/equipment and to assist in
technology reviews.
f. The facility operator shall purchase/lease or otherwise acquire zero-emission
vehicles/equipment (including: light/heavy duty trucks, drayage equipment,
forklifts and generators) when commercially available as the attrition of
gasoline/diesel equipment occurs. The property owner/tenant/lessee is
encouraged to utilize any or all funding opportunities offered by CARB and other
available programs. The availability of zero- emission equipment shall be

determined in a joint effort between the Airports Division and the facility operator
as part of an annual technology review.
g. The facility operator shall adhere to the findings of the annual technologies review
for reducing air emissions as part of the County Climate Action Plan and long-
range sustainability goals, which encourage property owners and tenants to use
cleaner technologies over time as they become available. A priority goal of the
review will be the replacement of older equipment in operation at the subject site
that generates the highest levels of criteria pollutant, TAC, and GHG emissions. The
equipment to be replaced will be determined based on the level of emissions and
cost-effectiveness of the emissions reduction (e.g., biggest reduction per dollar),
and identify implementation mechanisms including, but not limited to, tenant-
based improvements, grant programs, or a combination thereof, based on
regulatory requirements and the feasibility analysis performed by the Airports
Division. The Carl Moyer Program, or similar cost-effectiveness criteria, shall be
used to assess the economic feasibility (e.g., cost effectiveness) of the identified
new technologies. Zero-emission equipment employed pursuant to this mitigation
may be replaced by other technologies or other types of equipment as long as the
replacement equipment achieves the same or greater criteria pollutant, TAC, and
GHG emission reductions as compared to the equipment identified as part of the
technology review.
h. Every California based TRU and electronic-TRU (E-TRU) operational at the site must
be registered with the Air Resource Board Equipment Registration and shall be
labeled with a CARB Identification Number. Business operations handling TRUs
shall install charging infrastructure and encourage E-TRUs on site and require those
non-E-TRUs to plug in while stationary at the facility.
i. Prior to occupancy the facility operator shall demonstrate compliance with all
newly adopted Ordinances/Statutes/Plans and requirements passed by all
responsible agencies in relation to traffic, diesel emissions and air quality
improvement measures.
Biological Resources
12. Swainson’s Hawk Pre-Construction Survey, Avoidance, Minimization and Construction
Monitoring & Migratory Bird Treaty Act Nesting Bird Avoidance (MM-BIO-1):
a. Prior to any ground disturbance related to covered activities that occurs during the
nesting season (March 15–September 15), a qualified biologist shall conduct a
preconstruction survey no more than 1 month prior to construction to establish
whether Swainson’s hawk nests within 1,000 feet of the project site are occupied.
If potentially occupied nests within 1,000 feet are off the project site, then their
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 16 of 36
occupancy shall be determined by observation from public roads or by
observations of Swainson’s hawk activity (e.g., foraging) near the project site. If
nests are occupied, minimization measures and construction monitoring are
required (see below).
During the nesting season (March 15–September 15), covered activities within
1,000 feet of occupied nests or nests under construction shall be prohibited to
prevent nest abandonment. If site-specific conditions or the nature of the covered
activity (e.g., steep topography, dense vegetation, limited activities) indicate that a
smaller buffer could be used, the East Contra Costa County Habitat Conservancy
shall coordinate with the California Department of Fish and Wildlife (CDFW)/U.S.
Fish and Wildlife Service (USFWS) to determine the appropriate buffer size.
If young fledge prior to September 15, covered activities can proceed normally. If
the active nest site is shielded from view and noise from the project site by other
development, topography, or other features, the project proponent can apply to
the East Contra Costa County Habitat Conservancy for a waiver of this avoidance
measure. Any waiver must also be approved by USFWS and CDFW. While the nest
is occupied, activities outside the buffer can take place.
All active nest trees shall be preserved on site, if feasible. Nest trees, including non-
native trees, lost to covered activities shall be mitigated by planting 15 saplings for
every tree lost with the objective of having at least 5 mature trees established for
every tree lost according. Preference shall be to provide on-site mitigation if
feasible. Planting of replacement trees must be reviewed by the Airports Division
for compatibility with airport operations. The project proponent shall either pay
the East Contra Costa County Habitat Conservancy (Habitat Conservancy) an
additional fee to purchase, plant, maintain, and monitor 15 saplings on the East
Contra Costa County Habitat Conservation Plan (HCP)/Natural Community
Conservation Plan (NCCP) Preserve System for every tree lost, or the project
proponent shall plant, maintain, and monitor 15 saplings for every tree lost at a
site to be approved by the Habitat Conservancy and per the requirements of the
HCP/NCCP.
b. As part of the pre-construction survey for Swainson’s Hawk, the qualified biologist
approved by Contra Costa County shall also survey for native nesting birds
protected by the Migratory Bird Treaty Act. If any active nests are observed during
surveys, a suitable avoidance buffer from the nests shall be determined and
flagged by the qualified biologist based on species, location and planned
construction activity. Consultation with CDFW may be required to determine
appropriate buffer distances. These nests shall be avoided until the chicks have
fledged and the nests are no longer active, as determined by the qualified biologist.
Any habitat (i.e., trees and brush) would be removed outside of the breeding bird
season.

13. Western Burrowing Owl Pre-Construction Survey, Avoidance, Minimization, and
Construction Monitoring (MM-BIO-2):
a. In accordance with Conditions on Covered Activities described in the East Contra
Costa County Habitat Conservation Plan/Natural Community Conservation Plan,
prior to any ground disturbance related to covered activities, a U.S. Fish and
Wildlife Service (USFWS)/California Department of Fish and Wildlife (CDFW)-
approved biologist shall conduct a preconstruction survey in grassland areas
identified as having potential burrowing owl habitat. The surveys shall establish the
presence or absence of western burrowing owl and/or habitat features and
evaluate use by owls in accordance with CDFW survey guidelines (CDFG 1995).
b. On the parcel where the activity is proposed, the biologist shall survey the
proposed disturbance footprint and a 500-foot radius from the perimeter of the
proposed footprint to identify burrows and owls. Adjacent parcels under different
land ownership shall not be surveyed. Surveys should take place near sunrise or
sunset in accordance with CDFW guidelines. All burrows or burrowing owls shall
be identified and mapped. Surveys shall take place no more than 30 days prior to
construction. During the breeding season (February 1–August 31), surveys shall
document whether burrowing owls are nesting in or directly adjacent to
disturbance areas. During the nonbreeding season (September 1–January 31),
surveys shall document whether burrowing owls are using habitat in or directly
adjacent to any disturbance area. Survey results shall be valid only for the season
(breeding or nonbreeding) during which the survey is conducted.
c. This measure incorporates avoidance and minimization guidelines from CDFW’s
Staff Report on Burrowing Owl Mitigation (California Department of Fish and Game
1995).
d. If burrowing owls are found during the breeding season (February 1–August 31),
the project proponent shall avoid all nest sites that could be disturbed by project
construction during the remainder of the breeding season or while the nest is
occupied by adults or young. Avoidance shall include establishment of a non-
disturbance buffer zone (described below). Construction may occur during the
breeding season if a qualified biologist monitors the nest and determines that the
birds have not begun egg-laying and incubation or that the juveniles from the
occupied burrows have fledged. During the nonbreeding season (September 1–
January 31), the project proponent should avoid the owls and the burrows they are
using, if possible. Avoidance shall include the establishment of a buffer zone
(described below).
e. During the breeding season, buffer zones of at least 250 feet in which no
construction activities can occur shall be established around each occupied burrow
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 18 of 36
(nest site). Buffer zones of 160 feet shall be established around each burrow being
used during the nonbreeding season. The buffers shall be delineated by highly
visible, temporary construction fencing.
f. If occupied burrows for burrowing owls are not avoided, passive relocation shall
be implemented. Owls should be excluded from burrows in the immediate impact
zone and within a 160-foot buffer zone by installing one-way doors in burrow
entrances. These doors should be in place for 48 hours prior to excavation. The
project area should be monitored daily for 1 week to confirm that the owl has
abandoned the burrow. Whenever possible, burrows should be excavated using
hand tools and refilled to prevent reoccupation (CDFG 1995). Plastic tubing or a
similar structure should be inserted in the tunnels during excavation to maintain
an escape route for any owls inside the burrow.
14. California Red-Legged Frog Avoidance (MM-BIO-3):
a. Written notification to U.S. Fish and Wildlife Service (USFWS), California
Department of Fish and Wildlife (CDFW), and the East Contra Costa County Habitat
Conservancy, including, photos and habitat assessment, is required prior to
disturbance of any suitable breeding habitat. The project proponent shall also
notify these parties of the approximate date of removal of the breeding habitat at
least 30 days prior to this removal to allow USFWS or CDFW staff to translocate
individuals, if requested. USFWS or CDFW must notify the project proponent of
their intent to translocate California red-legged frog within 14 days of receiving
notice from the project proponent. The project proponent must allow USFWS or
CDFW access to the site prior to construction if they request it.
b. There are no restrictions under the East Contra Costa County Habitat Conservation
Plan/Natural Community Conservation Plan on the nature of the disturbance or the
date of the disturbance unless CDFW or USFWS notify the project proponent of
their intent to translocate individuals within the required time period. In this case,
the project proponent must coordinate the timing of disturbance of the breeding
habitat to allow USFWS or CDFW to translocate the individuals.
c. USFWS and CDFW shall be allowed 45 days to translocate individuals from the date
the first written notification was submitted by the project proponent (or a longer
period agreed to by the project proponent, USFWS, and CDFW).
15. California Tiger Salamander Minimization (MM-BIO-4):
a. Written notification to USFWS, CDFW, and the Implementing Entity, including
photos and breeding habitat assessment, is required prior to disturbance of any
suitable breeding habitat. The project proponent will also notify these parties of
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 19 of 36
the approximate date of removal of the breeding habitat at least 30 days prior to
this removal to allow USFWS or CDFW staff to translocate individuals, if requested.
USFWS or CDFW must notify the project proponent of their intent to translocate
California tiger salamanders within 14 days of receiving notice from the project
proponent. The applicant must allow USFWS or CDFW access to the site prior to
construction if they request it.
b. There are no restrictions under the East Contra Costa County Habitat Conservation
Plan/Natural Community Conservation Plan on the nature of the disturbance or the
date of the disturbance unless CDFW or USFWS notify the project proponent of
their intent to translocate individual California tiger salamanders within the
required time period. In this case, the project proponent must coordinate the
timing of disturbance of the breeding habitat to allow USFWS or CDFW to
translocate the individuals. USFWS and CDFW shall be allowed 45 days to
translocate individuals from the date the first written notification was submitted by
the project proponent (or a longer period agreed to by the project proponent,
USFWS, and CDFW).
16. Rare Plant Surveys and Mitigation (MM-BIO-5):
a. Prior to commencement of any project-related construction activity, Contra Costa
County shall retain a qualified biologist/botanist to conduct protocol-level special-
status plant surveys of the undisturbed areas of the project site for alkali milk-vetch
(Astragalus tener var. tener), brittlescale (Atriplex depressa), big tarplant
(Blepharizonia plumosa), round-leaved filaree (California macrophylla), Congdon’s
tarplant (Centromadia parryi ssp. congdonii), recurved larkspur (Delphinium
recurvatum), spiny-sepaled button-celery (Eryngium spinosepalum), diamond-
petaled poppy (Eschscholzia rhombipetala), and Contra Costa goldfields (Lasthenia
conjugens).
b. As part of the East Contra Costa County Habitat Conservation Plan (HCP)/Natural
Community Conservation Plan (NCCP) application for coverage, the surveys shall
be conducted during the appropriate blooming periods. The surveys shall be
conducted by a qualified biologist knowledgeable of the plant species in the
region. These plant surveys shall be conducted in accordance with 2009 California
Department of Fish and Wildlife (CDFW) rare plant survey protocols.
c. If any special-status plant species are observed during surveys, the project
proponent shall notify the HCP/NCCP Implementing Entity (i.e., East Contra Costa
County Habitat Conservancy) of the construction schedule so as to allow the
HCP/NCCP Implementing Entity the option to salvage the population(s) in
accordance with HCP/NCCP Conservation Measure 3.10 (Plant Salvage when
Impacts are Unavoidable) described below. Additionally, the project proponent
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 20 of 36
shall confirm with the HCP/NCCP Implementing Entity that the take limits of the
HCP/NCCP for the species identified have not been reached.
d. The following special-status plant species with potential to occur on the project
site are covered by the HCP/NCCP: brittlescale, big tarplant, round-leaved filaree,
and recurved larkspur. Alkali milk-vetch, diamond-petaled poppy, and Contra
Costa goldfields are analyzed in the HCP/NCCP but are “no take” species, and
avoidance is the only acceptable mitigation measure.
e. Congdon’s tarplant and spiny-sepaled button-celery are not addressed in the
HCP/NCCP. For these plants, mitigation shall consist of, in order of preference, (1)
avoidance, (2) salvage and transplant as described below, or (3) off-site habitat
enhancement or restoration in consultation with CDFW.
17. Plant Salvage when Impacts are Unavoidable (Covered Species) (MM-BIO-5):
a. Perennial Covered Plants: Where impacts to covered plant species cannot be
avoided and plants will be removed by approved covered activities, the HCP/NCCP
Implementing Entity has the option of salvaging the covered plants. Salvage
methods for perennial species shall be tested for whole individuals, cuttings, and
seeds. Salvage measures shall include the evaluation of techniques for
transplanting as well as germinating seed in garden or greenhouse and then
transplanting to suitable habitat sites in the field.
Techniques shall be tested for each species, and appropriate methods shall be
identified through research and adaptive management. Where plants are
transplanted or seeds distributed to the field they shall be located in preserves in
suitable habitat to establish new populations. Field trials shall be conducted to
evaluate the efficacy of different methods and determine the best methods to
establish new populations. New populations shall be located such that they
constitute separate populations and do not become part of an existing population
of the species, as measured by the potential for genetic exchange among
individuals through pollen or propagule (e.g., seed, fruit) dispersal.
Transplanting within the preserves shall only minimally disturb existing native
vegetation and soils. Supplemental watering may be provided as necessary to
increase the chances of successful establishment, but must be removed following
initial population establishment. See also All Covered Plants, below.
b. Annual Covered Plants: For annual covered plants, mature seeds shall be collected
from all individuals for which impacts cannot be avoided (or if the population is
large, a representative sample of individuals). If storage is necessary, seed storage
studies shall be conducted to determine the best storage techniques for each
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 21 of 36
species. If needed, studies shall be conducted on seed germinated and plants
grown to maturity in garden or greenhouse to propagate larger numbers of seed.
Seed propagation methods shall ensure that genetic variation is not substantially
affected by propagation (i.e., selection for plants best adapted to cultivated
conditions). Field studies shall be conducted through the Adaptive Management
Program to determine the efficacy and best approach to dispersal of seed into
suitable habitat. Where seeds are distributed to the field, they shall be located in
preserves in suitable habitat to establish new populations. If seed collection
methods fail (e.g., due to excessive seed predation by insects), alternative
propagation techniques shall be necessary. See also All Covered Plants, below.
c. All Covered Plants: All salvage operations shall be conducted by the HCP/NCCP
Implementing Entity. To ensure enough time to plan salvage operations, project
proponents shall notify the HCP/NCCP Implementing Entity of their schedule for
removing the covered plant population.
The HCP/NCCP Implementing Entity may conduct investigations into the efficacy
of salvaging seeds from the soil seed bank for both perennial and annual species.
The soil seed bank may add to the genetic variability of the population. Covered
species may be separated from the soil though garden/greenhouse germination
or other appropriate means. Topsoil taken from impact sites shall not be
distributed into preserves because of the risk of spreading new non-native and
invasive plants to preserves.
The HCP/NCCP Implementing Entity will transplant new populations such that they
constitute separate populations and do not become part of an existing population
of the species, as measured by the potential for genetic exchange among
individuals through pollen or propagule (e.g., seed, fruit) dispersal. Transplanting
or seeding “receptor” sites (i.e., habitat suitable for establishing a new population)
should be carefully selected on the basis of physical, biological, and logistical
considerations (Fiedler and Laven 1996); some examples of these are listed below:
i. Historic range of the species.
ii. Soil type.
iii. Soil moisture.
iv. Topographic position, including slope and aspect.
v. Site hydrology.
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 22 of 36
vi. Mycorrhizal associates (this may be important for Mount Diablo
manzanita).
vii. Presence or absence of typical associated plant species.
viii. Presence or absence of herbivores or plant competitors.
ix. Site accessibility for establishment, monitoring, and protection from
trampling by cattle or trail users.
18. Wetlands and Waters of the United States or State (MM-BIO-6.a): Prior to
commencement of any project-related construction activity, Contra Costa County (County)
shall retain a qualified biologist or wetland scientist to prepare a jurisdictional delineation
of the project site to determine the extent of potentially jurisdictional features within the
project disturbance area. Impacts to wetlands and other waters of the United States or
waters of the state shall require authorization from the U.S. Army Corps of Engineers in
the form of a Clean Water Act (CWA) Section 404 Permit, from the Regional Water Quality
Control Board in the form of a CWA Section 401 Water Quality Certification, and the
California Department of Fish and Wildlife in the form of a California Fish and Game Code
Section 1602 Streambed Alteration Agreement. Such permits typically include measures
to avoid and minimize or mitigate impacts. Where avoidance of jurisdictional wetlands or
waters is not feasible, replacement of resources is required in the form of restoration or
creation. The project shall seek coverage under the East Contra Costa County Habitat
Conservation Plan (HCP)/Natural Community Conservation Plan (NCCP) for impacts to
jurisdictional waters or wetlands. If neither avoidance nor coverage under the HCP/NCCP
is feasible, the County shall comply with the requirements of the 404 permit coverage for
on- or off-site mitigation, at a replacement ration of no less than 1:1.
19. Brushy Creek Setback (MM-BIO-6.b): Per the requirements of the HCP/NCCP and Contra
Costa County General Plan policy, a development setback of 75 feet from Brushy Creek
(measured from top of bank) is required. Note that a lesser setback (for an area less than
300 linear feet) may be approved in consultation with the East Contra Costa Habitat
Conservancy.
20. Alkali Grassland Avoidance and Mitigation (MM-BIO-7): A portion of the aviation
development area, adjacent to the existing facilities, includes alkali grassland. Ultimate
development of this site shall require either avoidance, or establishment of like alkali
grassland outside of the development area, which shall be made under consultation with
the East Contra Costa County Habitat Conservancy. Because this area is relatively
disturbed, is isolated from similar habitat, and is maintained on an on-going basis by
airport staff, it does not represent an exemplary patch of alkali grassland. Mitigation ratios
for impacts to alkali grassland will be determined in consultation with the East Contra
Costa County Habitat Conservancy

21. San Joaquin Kit Fox Preconstruction Surveys, Avoidance and Minimization, and
Construction Monitoring (MM-BIO-8):
a. Prior to any ground disturbance related to covered activities, a USFWS/CDFW–
approved biologist shall conduct a preconstruction survey in areas identified in the
planning surveys as supporting suitable breeding or denning habitat for San
Joaquin kit fox. The surveys shall establish the presence or absence of San Joaquin
kit foxes and/or suitable dens and evaluate use by kit foxes in accordance with
USFWS survey guidelines (U.S. Fish and Wildlife Service 1999).
b. Preconstruction surveys shall be conducted within 30 days of ground disturbance.
On the parcel where the activity is proposed, the biologist shall survey the
proposed disturbance footprint and a 250-foot radius from the perimeter of the
proposed footprint to identify San Joaquin kit foxes and/or suitable dens. Adjacent
parcels under different land ownership shall not be surveyed. The status of all dens
shall be determined and mapped. Written results of preconstruction surveys shall
be submitted to USFWS within 5 working days after survey completion and before
the start of ground disturbance. Concurrence is not required prior to initiation of
covered activities.
c. If San Joaquin kit foxes and/or suitable dens are identified in the survey area, the
measures described below shall be implemented:
i. If a San Joaquin kit fox den is discovered in the proposed development
footprint, the den shall be monitored for 3 days by a USFWS/CDFW–
approved biologist using a tracking medium or an infrared beam camera
to determine if the den is currently being used.
ii. Unoccupied dens should be destroyed immediately to prevent subsequent
use.
iii. If a natal or pupping den is found, USFWS and CDFW shall be notified
immediately. The den shall not be destroyed until the pups and adults have
vacated and then only after further consultation with USFWS and CDFW.
iv. If kit fox activity is observed at the den during the initial monitoring period,
the den shall be monitored for an additional 5 consecutive days from the
time of the first observation to allow any resident animals to move to
another den while den use is actively discouraged. For dens other than natal
or pupping dens, use of the den can be discouraged by partially plugging
the entrance with soil such that any resident animal can easily escape. Once
the den is determined to be unoccupied it may be excavated under the
direction of the biologist. Alternatively, if the animal is still present after 5
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 24 of 36
or more consecutive days of plugging and monitoring, the den may have
to be excavated when, in the judgment of a biologist, it is temporarily
vacant (i.e., during the animal’s normal foraging activities).
d. If dens are identified in the survey area outside the proposed disturbance footprint,
exclusion zones around each den entrance or cluster of entrances shall be
demarcated. The configuration of exclusion zones should be circular, with a radius
measured outward from the den entrance(s). No covered activities shall occur
within the exclusion zones. Exclusion zone radii for potential dens shall be at least
50 feet and shall be demarcated with four to five flagged stakes. Exclusion zone
radii for known dens shall be at least 100 feet and shall be demarcated with staking
and flagging that encircles each den or cluster of dens but does not prevent access
to the den by kit fox.
22. East Contra Costa County HCP/NCCP Covered Shrimp Preconstruction Survey, Avoidance
and Minimization, and Construction Monitoring (MM-BIO-9):
a. Prior to any ground disturbance related to covered activities, a USFWS-approved
biologist shall conduct a preconstruction survey in areas identified in the planning
surveys as having suitable shrimp habitat. The surveys shall establish the presence
or absence of covered shrimp and/or habitat features and evaluate use by listed
shrimp in accordance with modified USFWS survey guidelines (USFWS 1996a).
Project proponents are required to conduct USFWS protocol surveys in 1 year
(rather than 2) to determine presence or absence of listed shrimp species. If
covered shrimp are absent from the site, there are no further requirements related
to covered shrimp. If covered shrimp are present, the following avoidance and
minimization and construction monitoring measures are required:
i. To the maximum extent practicable, impacts on occupied habitat of
covered shrimp shall be avoided by implementing the following measures
based on existing mitigation standards (USFWS 1996b).
ii. If suitable habitat for covered shrimp will be retained on site, establish a
buffer (described below) from the outer edge of all hydric vegetation
associated with seasonal wetlands occupied by covered shrimp.
Alternatively, at the request of the project proponent, representatives of
the East Contra Costa County Habitat Conservancy and USFWS may
conduct site visits to inspect the particular characteristics of specific project
sites and may approve reductions of the buffer. Buffer reductions may be
approved for all or portions of the site whenever reduced setbacks will
maintain the hydrology of the seasonal wetland and achieve the same or
greater habitat values as would be achieved by the original buffer.
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 25 of 36
iii. Activities inconsistent with the maintenance of seasonal wetlands within
the buffers and disturbance of the on-site watershed shall be prohibited.
Inconsistent activities include altering existing topography; placing new
structures within the buffers; dumping, burning, and/or burying garbage or
any other wastes or fill materials; building new roads or trails; removing or
disturbing existing native vegetation; installing storm drains; and using
pesticides or other toxic chemicals.
iv. Filling of seasonal wetlands, if unavoidable, shall be delayed until pools are
dry and samples from the top 4 inches of wetland soils are collected. Soil
collection will shall be sufficient to include a representative sample of plant
and animal life present in the wetland by incorporating seeds, cysts, eggs,
spores, and similar inocula. The amount of soil collected shall be
determined by the size of the wetland filled and the variation in physical
and biological conditions within the wetland. The number and size of
samples shall be sufficient to capture this variation. For very small wetlands
it may be most cost effective to simply collect all topsoil. These samples
shall be provided to the East Contra Costa County Habitat Conservancy so
that the soil can be translocated to suitable habitat within the inventory
area unoccupied by covered shrimp or used to inoculate newly created
seasonal wetlands on preserve lands.
v. Seasonal wetlands occupied by covered shrimp that are filled shall be offset
by preserving or acquiring seasonal wetlands occupied by the covered
shrimp species and restoring habitat suitable for the covered shrimp
species in accordance with Conservation Measure 3.8. Such mitigation shall
supersede requirements for mitigation of impacts on wetland habitat when
covered species are present.
b. If suitable habitat for covered shrimp shall be retained on site, project proponents
shall establish a buffer from the outer edge of all hydric vegetation associated with
seasonal wetlands occupied (or assumed to be occupied) by covered shrimp. This
buffer zone shall be determined in the field by the biologists as the immediate
watershed feeding the seasonal wetland or a minimum of 50 feet, whichever is
greater. Buffers shall be marked by brightly colored fencing or flagging throughout
the construction process. Activities shall be prohibited within this buffer in
accordance with the minimization measure above.
c. Construction personnel shall be trained to avoid affecting shrimp. A qualified
biologist approved by USFWS shall inform all construction personnel about the life
history of covered shrimp, the importance of avoiding their habitat, and the terms
and conditions of the Eastern Contra Costa County Habitat Conservation

Plan/Natural Community Conservation Plan related to avoiding and minimizing
impacts on covered shrimp.
Cultural Resources
23. Accidental Discovery of Archaeological Resources (MM-CUL-1): Prior to commencement
of any construction activities involving ground disturbance, Contra Costa County, a
qualified archaeologist, representatives from interested Native American Tribes, and the
construction contractor shall be invited to meet or otherwise discuss by conference call
the project site’s archaeological sensitivity and determine the duration and extent of
monitoring for archaeological deposits that may be uncovered during construction. Given
the present disturbed condition in some locations surrounding existing airport facilities,
areas of elevated potential for encountering unanticipated resources should be considered
those within 500 feet of the historic-era corral and Brushy Creek, and no deeper than 4
feet below the present ground surface. An archaeological monitor and a monitor from a
culturally affiliated Native American Tribe shall be present for initial ground-disturbing
work in these areas, after which the monitoring frequency shall be reduced to periodic
spot-checks elsewhere. The monitoring strategy shall be adjusted (increased, decreased,
or discontinued) based on the results of monitoring within areas of elevated
archaeological sensitivity and as recommended by a qualified archaeologist meeting the
Secretary of the Interior’s Professional Qualification Standards, in consultation with
culturally affiliated Native American Tribes. In the event that archaeological resources are
exposed, work within 100 feet of the find shall be halted or directed to another location
until a qualified archaeologist can evaluate the significance of the find. If the resources are
determined to be historical resources or unique (pursuant to Section 15064.5 of the CEQA
Guidelines), the qualified archaeologist shall make recommendations prioritizing resource
avoidance, or, where avoidance is infeasible, data recovery.
24. Accidental Discovery of Human Remains (MM-CUL-2): Pursuant to Section 5097.98 of the
California Public Resources Code and Section 7050.5 of the California Health and Safety
Code, as well as California Environmental Quality Act Guidelines Section 15064.5(e), in the
event of the discovery of human remains, work shall be suspended within 100 feet of the
find, and the Contra Costa County (County) Coroner/Sheriff shall be immediately notified.
The County Coroner/Sheriff shall determine if an investigation is necessary. If the remains
are determined to be Native American:
a. The Coroner shall contact the Native American Heritage Commission (NAHC)
within 24 hours.
b. The NAHC shall identify the person or persons it believes to be the most likely
descendant (MLD) from the deceased Native American.
CPC – March 9, 2022

Findings & COAs Page 27 of 36
c. The MLD shall have an opportunity to make a recommendation to the County for
means of treating or disposing of, with appropriate dignity, the human remains
and any associated grave goods as provided in California Public Resources Code
Section 5097.98.
25. Should a potential tribal cultural resource (TCR) be inadvertently encountered,
construction activities within 100 feet of the TCR shall be halted and Contra Costa County
Department of Conservation and Development (Department) notified. The Department
shall notify Native American tribes that have been identified by the Native American
Heritage Commission to be traditionally and culturally affiliated with the geographic area
of the project. Any affected tribe shall be provided a reasonable period of time to conduct
a site visit and make recommendations regarding future ground disturbance activities as
well as the treatment and disposition of any discovered TCR. Depending on the nature of
the potential resource and tribal recommendations, review by a qualified archaeologist
may be required. Implementation of proposed recommendations shall be made based on
the determination of the County that the approach is reasonable and feasible. All activities
shall be conducted in accordance with regulatory requirements. (MM-CUL-3)
26. Worker Environmental Awareness Program (WEAP) (MM-CUL-4): The County shall require
the contractor to provide a cultural resources and tribal cultural resources sensitivity and
awareness training program (Worker Environmental Awareness Program [WEAP]) for all
personnel involved in project construction, including field consultants and construction
workers. The WEAP shall be developed in coordination with an archaeologist meeting the
Secretary of the Interior’s Professional Qualifications Standards for Archeology, as well as
culturally affiliated Native American tribes. The County will invite Native American
representatives from interested culturally affiliated Native American tribes to participate.
The WEAP shall be conducted before any ground-disturbing construction activities begin
at the project site. The WEAP shall include relevant information regarding sensitive cultural
resources and tribal cultural resources, including applicable regulations, protocols for
avoidance, and consequences of violating State laws and regulations.
The WEAP shall also describe appropriate avoidance and impact minimization measures
for cultural resources and tribal cultural resources that could be located at the project site
and shall outline what to do and who to contact if any potential cultural resources or tribal
cultural resources are encountered. The WEAP shall emphasize the requirement for
confidentiality and culturally appropriate treatment of any discovery of significance to
Native Americans and shall discuss appropriate behaviors and responsive actions,
consistent with Native American tribal values.
Geology, Soils, and Minerals
27. Prior to the approval of any building or improvement plans, a geotechnical report shall be
prepared by a registered civil or geotechnical engineer and submitted to the County
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Findings & COAs Page 28 of 36
Department of Conservation and Development. The report shall address the specific
approach to development. This report shall include the following (MM-GEO-1):
a. Provide specific criteria and standards for identifying suitable imported fill
materials;
b. If import fills may be expansive or corrosive, provisions shall be made for the
import fill materials;
c. If import fills may be expansive or corrosive, provisions shall be made for testing
of soils on rough-graded pads and providing design measures to avoid/control
damage to foundations and buried utilities;
d. Provide criteria for placement of engineered fill;
e. Provide further evaluation of seismic settlement and other types of seismically
induced ground failure by recognized methods appropriate to soil conditions
discovered during subsurface investigation;
f. Provide detailed evaluation of the compressibility of the alluvial soils and forecast
the anticipated amount of total settlement and timing of settlement to occur or
placing a surcharge on the site to speed settlement;
g. Provide California Building Code seismic parameters;
h. Outline recommendations for geotechnical observation and testing services during
site preparation-, grading-and foundation-related work. Improvement, grading,
and building plans shall carry out the recommendations of the approved report.
28. If paleontological resources (i.e., fossil bones, teeth, shells, plants, or trace fossils) are
exposed during construction activities for the project, all construction work occurring
within 100 feet of the find shall immediately stop until a qualified paleontologist, meeting
the Society of Vertebrate Paleontology standards, can evaluate the significance of the find
and determine whether or not additional study is warranted. The paleontologist shall be
empowered to temporarily stop or redirect grading activities to allow removal of abundant
or large paleontological resources. Depending upon the significance of the find, the
qualified paleontologist may simply remove and record the find and allow work to
continue. If the discovery proves significant under the California Environmental Quality
Act, additional work, such as data recovery and extended specimen removal, may be
warranted. The qualified paleontologist shall prepare a Paleontological Resources Impact
Mitigation Program for the project, which outlines where paleontological monitoring is
required based on the location of the discovery, geotechnical reports, and construction
plans. The qualified paleontologist shall also be required to curate specimens in a

the minimum amount of auto parking shall be provided to encourage alternative
forms of travel.
b. Install conduits from the building(s) to the parking lot(s), to allow for installation of
EV charging stations for vehicles. The proportion of EV parking spaces shall comply
with the applicable CALGreen standards.
c. The proposed project shall promote ridesharing programs through a multifaceted
approach, such as designating a certain percentage of parking spaces for
ridesharing vehicles; designating adequate passenger loading and unloading and
waiting areas for ridesharing vehicles; or providing a website or message board for
coordinating rides.
d. The proposed project shall implement marketing strategies to reduce commute
trips. Information sharing and marketing are important components to successful
commute trip-reduction strategies. Implementing commute trip-reduction
strategies without a complementary marketing strategy would result in lower
vehicle miles traveled reductions. Marketing strategies may include: new employee
orientation of trip reduction and alternative mode options; event promotions; or
publications.
30. The individual development projects shall include the following design features to reduce
the demand for energy use and greenhouse gas emissions (MM-GHG-2):
a. Obtain Leadership in Energy and Environmental Design (LEED) Certification for
building construction, where feasible.
b. Provide the maximum amount of skylights to reduce electricity use associated with
interior lighting.
c. All facility lighting shall meet or exceed the applicable Title 24 requirements.

d. All installed appliances (e.g., washer/dryers, refrigerators, dishwashers) shall be
Energy Star rated or equivalent.
e. Design proposed buildings with:
i. Roof structure with additional load (defined as 1 to 2 pounds per square
foot) capacity to allow the future installation of solar panels without
retrofitting. The installation of solar panels would comply with the policy
and procedures set forth in the Interim Policy for FAA Review of Solar
Energy System Projects on Federally Obligated Airports (78 FR 63276).
ii. Installation of an above market sized electrical infrastructure system (larger
electrical room for future expansion, underground conduits (car, truck and

conduits into the grid system for future expand-ability.
31. The individual development projects shall incorporate the following design features to
conserve water (MM-GHG-3):
a. Install low flow plumbing fixtures, such as faucets, toilets, and showers.
b. Utilize water efficient landscaping to reduce the usage of outdoor water on the
premises.
c. Construct dual plumbing for both potable and recycled water for exterior
landscape irrigation, unless determined infeasible by Department of Conservation
and Development, Current Planning Division
Hazards and Hazardous Materials
32. Prior to initiation of grading and construction, a Hazardous Materials Contingency Plan
shall be in-place and consist of the following (MM-HAZ-1):
a. Identification of areas of potential fuel- or oil-impacted soils on a site plan.
b. Protocol for identifying suspected contaminated soils (e.g., discoloring, odor,
positive photoionization detector readings), utilizing personnel trained in
recognition of contaminated soils/groundwater and certified with respect to
Occupational Safety and Health Administration Hazardous Waste Operations and

33. Prior to development of the former agricultural areas identified ion Figure 3.7-1, Hazards
Site Map, soil samples shall be collected and tested for pesticides. Shallow soil samples
shall be collected from the upper 0.5 to –1.0 foot of ground surface from the site soils and
analyzed for organochlorine pesticides by U.S. Environmental Protection Agency (EPA)
Method 8081A and arsenic by EPA Method 6010B. The soil samples shall be analyzed by
a California Environmental Laboratory Accreditation Program-certified laboratory.
The pesticide sampling data shall be compared to applicable regulatory threshold levels
such as the EPA Regional Screening Levels and the Department of Toxic Substances
Control Human and Ecological Risk Office Note 3 screening levels. The arsenic sampling
data shall be compared to California typical background levels, such as those in the 1996
Kearney Foundation Special Report on Background Concentrations of Trace and Major
Elements in California Soils.
If the soil sampling concentrations, using the 95% upper confidence level or other
statistical evaluation, exceed the screening level, mitigation shall include removal of
impacted soil for off-site disposal prior to or during construction grading. A soil
management plan, including a health and safety plan, shall be prepared to properly
manage the excavated soil and protect worker and public health and safety.

rates and volumes under 10- 25-, 50- and 100-year storm events, and to provide
recommendations for needed improvements. The Hydrology and Drainage Study
shall quantify the capacity of the existing detention basin; determine whether or
not it will be sufficient to serve future land uses; and establish the hydrology
performance criteria and design standards applicable to potential future tenants,
based on the destination of runoff (i.e., detention basin or Bushy Creek) and the
degree of impervious surface coverage. The study shall be consistent with the
hydrology performance criteria and design standards contained within the Contra
Costa County Drainage Ordinance (Division 914), which include but are not limited
to:
i. Drainage facilities shall be designed to convey a minimum (with sufficient
freeboard) of the runoff produced by a) a 10-year storm event for facilities
draining an area of less than 1 square mile, b) a 25-year storm event for
facilities draining an area of between 1 and 4 square miles, and c) a 50-year
storm event (and 100-year event without freeboard) for facilities draining
an area of more than 4 square mile.
ii. Finished floors shall be elevated above the base flood elevation of the one-
hundred-year frequency storm runoff, as determined using the maximum
potential development of the drainage basin or watershed shall.
iii. Storm flows shall be collected and conveyed in a manner that avoids
damage to any improvement, building site or dwelling which may be
constructed as part of the project.
iv. Detention basins shall be sized to contain without freeboard a one-
hundred-year average recurrence interval runoff, unless it can be shown
that a one- hundred-year average recurrence interval runoff can be safely
passed through the detention basin without damage to the detention basin
or any other property.
v. Drainage capacity shall be provided that accounts for the full build-out of
uses anticipated with the drainage area.
b. The study shall be submitted to the Contra Costa County Public Works Department
(Flood Control District) for review and approval prior to finalizing individual
development plans. In addition, the Hydrology and Drainage Study shall be
reviewed by Airports Division staff to ensure any drainage basins proposed are
consistent with Federal Aviation Administration aviation obstruction standards for
avian attractants (e.g., requirement to drain ponded water within 48 hours of a
major storm event).

35. Drainage Protection and Flood Control (MM-HYD-2): For all areas of the project within
the Federal Emergency Management Agency (FEMA) 100-year floodplain (Special Flood
Hazard Area [SFHA]), Contra Costa County shall ensure that development proposals are
consistent with the requirements of the Contra Costa County Floodplain Management
Ordinance (Municipal Code Chapter 82-28), Contra Costa County Flood Control Ordinance,
and FEMA National Flood Insurance Program. Development proposals in this area shall be
submitted to the Contra Costa County Public Works Department for review and approval,
and all requirements imposed by the department shall be satisfied. Such requirements
may include floodproofing measures (such as elevating structures above the base flood
elevation and providing the required freeboard). In the event development proposals
involve encroachment onto or undergrounding of Brushy Creek, a Clean Water Act Section
404 Permit from the U.S. Army Corps of Engineers shall be obtained, per MM-BIO-6, and
the Contra Costa County Public Works Department shall be provided with drainage studies
and engineering reports sufficient to demonstrate that flood flows on Brushy Creek would
not be impeded or redirected. For all development planned within the FEMA 100-year
floodplain, subject to approval of the Contra Costa County Public Works Department, the
developer would be required to file a Conditional Letter of Map Revision to process the
change and shall obtain a FEMA modification of the SFHA as shown on the Flood Insurance

Utilities
49. Prior to (1) the development of non-aviation uses, or (2) the expansion of aviation uses
that would increase water demand in excess of the current well system, Contra Costa
County (County) shall conduct a feasibility study of the water supply sources identified in
the proposed project’s Water Supply Assessment. If the water supply is to consist of
connection to the Byron-Bethany Irrigation District or the Town of Discovery Bay, the
County shall not permit development to proceed until the feasibility of the water supply
has been confirmed, and appropriate agreements or will-serve letters have been obtained
from the chosen supplier(s). If part or all of the supply is to come from on-site
groundwater, the County shall obtain a water supply permit from the State Water Resource
Control Board Division of Drinking Water, a well drilling permit from Contra Costa County
Public Works, and all other applicable permits and approvals prior to development. The
feasibility study, will-serve letters, and water supply permit(s) approvals shall be required
prior to the start of construction of any uses that involve human occupancy or demand
water in excess of currently available supply. (MM-UTIL-1)
50. Prior to (1) the development of non-aviation uses, or (2) the expansion of aviation uses
that involve additional human occupancy, Contra Costa County shall prepare a study for
the provision of adequate wastewater disposal. Options for disposal to be studied may
include expansion of the on-site septic system, construction of an on-site package
wastewater plant, and connection to the Town of Discovery Bay or Byron-Bethany
Irrigation District sewer systems. The study shall demonstrate feasibility of the proposed

EXECUTIVE SUMMARY
ES.1 INTRODUCTION
Contra Costa County (County) has prepared this Draft Final Environmental Impact Report (EIR)
to inform the community, responsible agencies, trustee agencies, and other interested agencies and
organizations, of the potential significant environmental effects resulting from implementation of
the proposed Byron Airport Development Program (project) and the mitigation measures or project
alternatives that would avoid or substantially reduce those effects. This Draft Final EIR was
prepared in compliance with the California Environmental Quality Act (CEQA) (California Public
Resources Code, Section 21000 et seq.) and the CEQA Guidelines (14 CCR 15000 et seq.).
ES.2 SUMMARY OF IMPACTS
Table ES-1 presents a summary of the potentially significant environmental impacts that could result
from the project, proposed mitigation measures, and the level of significance of the impact after the
implementation of the mitigation measures.

views of the site and its surroundings
MM-AES-1: Non-aviation development shall be subject to the following design requirements:
• Long facades should be designed with building articulation and landscaping to break
them up into smaller visual elements, avoiding public views of uninterrupted blank walls.
• For industrial and warehouse buildings, bright reflective colors and materials shall not be
allowed. Paint colors should be earth tones. Natural finishes such as brick or stone
facades may also be incorporated into the design.
• Project lighting shall comply with the policies of the Airport Land Use Compatibility Plan.
• Loading areas should be located and designed to minimize direct exposure to public
views.
• Structures and parking lots located on the eastern edge of the airport property shall
incorporate landscaping to screen public views. The type, quantity and placement of plant
material should be selected for its compatibility with airport uses (tree heights, plants that
are not wildlife attractants), as well as structure, texture, color and compatibility with the
building design and materials.
The design of non-aviation development shall be reviewed by both Department of
Conservation and Development and Airports Division staff prior to issuance of building
permits for conformance with these standards. Aviation uses shall be reviewed by Airports
Division staff.

• 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.
• All vehicle speeds on unpaved roads shall be limited to 15 mph.
• 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.
• 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, 13 CCR 2485). Clear signage shall be provided for construction
workers at all access points.
• All construction equipment shall be maintained and properly tuned in accordance with
manufacturer’s specifications. All equipment shall be checked by a certified mechanic
and determined to be running in proper condition prior to operation.
• 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 BAAQMD’s phone number shall also be visible to ensure
compliance with applicable regulations.
MM-AQ-2: The project shall implement the following measures for all facilities in order to
reduce operational air pollutant emissions to the extent feasible. To the extent that the
measures below are addressed by MM-AQ-4 as part of any health risk assessment that is
prepared, the measures in MM-AQ-4 shall take precedence.
• Only haul trucks meeting model year 2010 engine emission standards shall be used for
the on-road transport of materials to and from the project site.
• Legible, durable, weather-proof signs shall be placed at truck access gates, loading
docks, and truck parking areas that identify applicable anti-idling regulations. At a
minimum, each sign shall include: 1) instructions for truck drivers to shut off engines

manager and the CARB to report violations.
• Prior to tenant occupancy, the facility operator shall provide documentation to Contra
Costa County demonstrating that occupants/tenants of the project site have been
provided documentation on funding opportunities, such as the Carl Moyer Program, that
provide incentives for using cleaner-than-required engines and equipment.
• The minimum number of automobile electric vehicle (EV) charging stations required by
the California Code of Regulations Title 24 shall be provided. In addition, the buildings
shall include electrical infrastructure sufficiently sized to accommodate the potential
installation of additional auto and truck EV charging stations in the future.
• Conduit shall be installed to tractor trailer parking areas in logical locations determined by
the facility operator during construction document plan check, for the purpose of
accommodating the future installation of EV truck charging stations at such time this
technology becomes commercially available.
Impact 3.2-3: The project could expose sensitive
receptors to substantial pollutant concentrations.
MM-AQ-3: For non-aviation facilities with construction proposed within 1,000 feet of off-site
residential receptors, a construction health risk assessment shall be prepared to assess
exposure of existing sensitive receptors to toxic air contaminants (TACs) during project
construction. If the health risk assessment determines that cancer and non-cancer impacts
would be less than significant, no additional measures are needed. Alternatively, the results
of the health risk assessment may necessitate implementation of TAC exposure reduction
strategies in order to reduce potential risk to less-than-significant levels, which could include,
but are not limited to, the following:
• Portable equipment used during construction shall be powered by electricity from the grid
instead of diesel-powered generators, to the maximum amount feasible.
• Equip heavy-duty diesel-powered construction equipment with Tier 4 Interim or better
diesel engines, except where Tier 4 Interim or better engines are not available for specific
construction equipment. Contra Costa County shall verify and approve all pieces within
the construction fleet that would not meet Tier 4 Interim standards. At a minimum, Tier 3
engines will be required if Tier 4 engines are not available.

MM-AQ-4: For non-aviation uses, a health risk assessment of long-term operations shall be
prepared if the proposed facility is within 1,000 feet of off-site residential receptors and would
result in any of the following:
• Accommodate more than 100 trucks per day, or
• Accommodate more than 40 trucks with operating TRUs per day, or
• Where TRU operations exceed 300 hours per week.
Results of the health risk assessment may necessitate implementation of TAC exposure
reduction strategies in order to reduce potential risk to less-than-significant levels, which
could include, but are not limited to, the following:
• Idling of diesel equipment of any type shall be strictly prohibited at the premises. The
property facility operator shall inform all business partners, visitors, etc., of the Zero-Idling
Rule in effect for the subject property and area streets. Highly visible signs prohibiting
idling shall be posted at each entrance and exist. Violators of this zero-idling rule are
subject to fines and or criminal charges.
• Within 90 days of occupying the space, the facility operator shall submit to the Airports
Division and the Department of Conservation and Development (DCD) the first of an
annual inventory of all equipment that generates criteria pollutant, TACs, and GHG
emissions operated at the subject location throughout the life of the project up to year
2035. The equipment inventory shall include the year, make, and model of the equipment
that was used in the previous year, including annual hours of operation for each piece of
equipment, including but not limited to heavy-duty drayage and non-drayage trucks, yard
equipment, bulk material handling equipment (forklifts, etc.), and any other type of
material handling equipment. The purpose of the inventory is to track
emissions/equipment and to assist in technology reviews.
• The facility operator shall purchase/lease or otherwise acquire zero-emission
vehicles/equipment (including: light/heavy duty trucks, drayage equipment, forklifts and
generators) when commercially available as the attrition of gasoline/diesel equipment

opportunities offered by CARB and other available programs. The availability of zero-
emission equipment shall be determined in a joint effort between the Airports Division and
the facility operator as part of an annual technology review.
• The facility operator shall adhere to the findings of the annual technologies review for
reducing air emissions as part of the County Climate Action Plan and long-range
sustainability goals, which encourage property owners and tenants to use cleaner
technologies over time as they become available. A priority goal of the review shall be the
replacement of older equipment in operation at the subject site that generates the highest
levels of criteria pollutant, TAC, and GHG emissions. The equipment to be replaced shall
be determined based on the level of emissions and cost-effectiveness of the emissions
reduction (e.g., biggest reduction per dollar), and identify implementation mechanisms
including, but not limited to, tenant-based improvements, grant programs, or a
combination thereof, based on regulatory requirements and the feasibility analysis
performed by the Airports Division. The Carl Moyer Program, or similar cost-effectiveness
criteria, shall be used to assess the economic feasibility (e.g., cost effectiveness) of the
identified new technologies. Zero-emission equipment employed pursuant to this
mitigation may be replaced by other technologies or other types of equipment as long as
the replacement equipment achieves the same or greater criteria pollutant, TAC, and
GHG emission reductions as compared to the equipment identified as part of the
technology review.
• Every California based TRU and electronic-TRU (E-TRU) operational at the site must be
registered with the Air Resource Board Equipment Registration and shall be labeled with
a CARB Identification Number. Facility operators handling TRUs shall install charging
infrastructure and encourage E-TRUs on site, and require those non-E-TRUs to plug in
while stationary at the facility.
• Prior to occupancy the facility operator shall demonstrate compliance with all newly
adopted Ordinances/Statutes/Plans and requirements passed by all responsible agencies
in relation to traffic, diesel emissions and air quality improvement measures.

Impact 3.3-1: The project would not 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.
MM-BIO-1: a. Swainson’s Hawk Pre-Construction Survey, Avoidance, Minimization and
Construction Monitoring. Prior to any ground disturbance related to covered activities that
occurs during the nesting season (March 15–September 15), a qualified biologist shall
conduct a preconstruction survey no more than 1 month prior to construction to establish
whether Swainson’s hawk nests within 1,000 feet of the project site are occupied. If
potentially occupied nests within 1,000 feet are off the project site, then their occupancy shall
be determined by observation from public roads or by observations of Swainson’s hawk
activity (e.g., foraging) near the project site. If nests are occupied, minimization measures
and construction monitoring are required (see below).
During the nesting season (March 15–September 15), covered activities within 1,000 feet of
occupied nests or nests under construction shall be prohibited to prevent nest abandonment.
If site-specific conditions or the nature of the covered activity (e.g., steep topography, dense
vegetation, limited activities) indicate that a smaller buffer could be used, the East Contra
Costa County Habitat Conservancy shall coordinate with the California Department of Fish
and Wildlife (CDFW)/U.S. Fish and Wildlife Service (USFWS) to determine the appropriate
buffer size.
If young fledge prior to September 15, covered activities can proceed normally. If the active
nest site is shielded from view and noise from the project site by other development,
topography, or other features, the project proponent can apply to the East Contra Costa
County Habitat Conservancy for a waiver of this avoidance measure. Any waiver must also
be approved by USFWS and CDFW. While the nest is occupied, activities outside the buffer
can take place.
All active nest trees shall be preserved on site, if feasible. Nest trees, including non-native
trees, lost to covered activities will be mitigated by the project proponent according to the
requirements below.
Mitigation for Loss of Nest Trees

• If feasible on-site, planting 15 saplings for every tree lost with the objective of
having at least 5 mature trees established for every tree lost according to the
requirements listed below.
AND either
1. Pay the Implementing Entity an additional fee to purchase, plant, maintain, and
monitor 15 saplings on the HCP/NCCP Preserve System for every tree lost according to the
requirements listed below, OR
2. The project proponent will plant, maintain, and monitor 15 saplings for every tree
lost at a site to be approved by the Implementing Entity (e.g., within an HCP/NCCP Preserve
or existing open space linked to HCP/NCCP preserves), according to the requirements listed
below.
The following requirements will be met for all planting options:
• Tree survival shall be monitored at least annually for 5 years, then every other year
until year 12. All trees lost during the first 5 years will be replaced. Success will be
reached at the end of 12 years if at least 5 trees per tree lost survive without
supplemental irrigation or protection from herbivory. Trees must also survive for at
least three years without irrigation.
• Irrigation and fencing to protect from deer and other herbivores may be needed for
the first several years to ensure maximum tree survival.
• Native trees suitable for this site should be planted. When site conditions permit, a
variety of native trees will be planted for each tree lost to provide trees with different
growth rates, maturation, and life span, and to provide a variety of tree canopy
structures for Swainson’s hawk. This variety will help to ensure that nest trees will
be available in the short term (5-10 years for cottonwoods and willows) and in the
long term (e.g., Valley oak, sycamore). This will also minimize the temporal loss of
nest trees.
• Riparian woodland restoration conducted as a result of covered activities (i.e., loss
of riparian woodland) can be used to offset the nest tree planting requirement
above, if the nest trees are riparian species.

• Whenever feasible and when site conditions permit, trees should be planted in
clumps together or with existing trees to provide larger areas of suitable nesting
habitat and to create a natural buffer between nest trees and adjacent development
(if plantings occur on the development site).
• Whenever feasible, plantings on the site should occur closest to suitable foraging
habitat outside the UDA.
• Trees planted in the HCP/NCCP preserves or other approved offsite location will
occur within the known range of Swainson’s hawk in the inventory area and as
close as possible to high-quality foraging habitat.
b. Migratory Bird Treaty Act Nesting Bird Avoidance. As part of the pre-construction
survey for Swainson’s Hawk, the qualified biologist approved by USFWS/CDFW shall also
survey for native nesting birds protected by the Migratory Bird Treaty Act. If any active nests
are observed during surveys, a suitable avoidance buffer from the nests shall be determined
and flagged by the qualified biologist based on species, location and planned construction
activity. Consultation with CDFW may be required to determine appropriate buffer distances.
These nests shall be avoided until the chicks have fledged and the nests are no longer
active, as determined by the qualified biologist. Habitat (i.e., trees and brush) may not be
removed during the breeding bird season.
MM-BIO-2: Western Burrowing Owl Pre-Construction Survey, Avoidance, Minimization,
and Construction Monitoring. In accordance with Conditions on Covered Activities
described in the East Contra Costa County HCP/NCCP, prior to any ground disturbance
related to covered activities, a U.S. Fish and Wildlife Service (USFWS)/California Department
of Fish and Wildlife (CDFW)-approved biologist shall conduct a preconstruction survey in
areas identified as having potential burrowing owl habitat. The surveys will establish the
presence or absence of western burrowing owl and/or habitat features and evaluate use by
owls in accordance with CDFW survey guidelines (CDFG 1995).
On the parcel where the activity is proposed, the biologist will survey the proposed
disturbance footprint and a 500-foot radius from the perimeter of the proposed footprint to
identify burrows and owls. Adjacent parcels under different land ownership will not be
surveyed. Surveys should take place near sunrise or sunset in accordance with CDFW

guidelines. All burrows or burrowing owls will be identified and mapped. Surveys will take
place no more than 30 days prior to construction. During the breeding season (February 1–
August 31), surveys will document whether burrowing owls are nesting in or directly adjacent
to disturbance areas. During the nonbreeding season (September 1–January 31), surveys
will document whether burrowing owls are using habitat in or directly adjacent to any
disturbance area. Survey results will be valid only for the season (breeding or nonbreeding)
during which the survey is conducted.
This measure incorporates avoidance and minimization guidelines from CDFW’s Staff Report
on Burrowing Owl Mitigation (California Department of Fish and Game 1995).
If burrowing owls are found during the breeding season (February 1–August 31), the project
proponent will avoid all nest sites that could be disturbed by project construction during the
remainder of the breeding season or while the nest is occupied by adults or young.
Avoidance will include establishment of a non-disturbance buffer zone (described below).
Construction may occur during the breeding season if a qualified biologist monitors the nest
and determines that the birds have not begun egg-laying and incubation or that the juveniles
from the occupied burrows have fledged. During the nonbreeding season (September 1–
January 31), the project proponent should avoid the owls and the burrows they are using, if
possible. Avoidance will include the establishment of a buffer zone (described below).
During the breeding season, buffer zones of at least 250 feet in which no construction
activities can occur will be established around each occupied burrow (nest site). Buffer zones
of 160 feet will be established around each burrow being used during the nonbreeding
season. The buffers will be delineated by highly visible, temporary construction fencing.
If occupied burrows for burrowing owls are not avoided, passive relocation will be
implemented. Owls should be excluded from burrows in the immediate impact zone and
within a 160-foot buffer zone by installing one-way doors in burrow entrances. These doors
should be in place for 48 hours prior to excavation. The project area should be monitored
daily for 1 week to confirm that the owl has abandoned the burrow. Whenever possible,
burrows should be excavated using hand tools and refilled to prevent reoccupation (CDFG
1995). Plastic tubing or a similar structure should be inserted in the tunnels during excavation
to maintain an escape route for any owls inside the burrow.

MM-BIO-5: Rare Plant Surveys and Mitigation. Prior to commencement of any project-
related construction activity, Contra Costa County shall retain a qualified biologist/botanist to
conduct protocol-level special-status plant surveys of the undisturbed areas of the project site
for alkali milk-vetch (Astragalus tener var. tener), brittlescale (Atriplex depressa), big tarplant
(Blepharizonia plumosa), round-leaved filaree (California macrophylla), Congdon’s tarplant
(Centromadia parryi ssp. congdonii), recurved larkspur (Delphinium recurvatum), spiny-
sepaled button-celery (Eryngium spinosepalum), diamond-petaled poppy (Eschscholzia
rhombipetala), and Contra Costa goldfields (Lasthenia conjugens).
As part of the East Contra Costa County Habitat Conservation Plan (HCP)/Natural
Community Conservation Plan (NCCP) application for coverage, the surveys shall be
conducted during the appropriate blooming periods. The surveys shall be conducted by a
qualified biologist knowledgeable of the plant species in the region. These plant surveys shall
be conducted in accordance with 2009 California Department of Fish and Wildlife (CDFW)
rare plant survey protocols.
If any special-status plant species are observed during surveys, the project proponent shall
notify the HCP/NCCP Implementing Entity (i.e., East Contra Costa County Habitat
Conservancy) of the construction schedule so as to allow the HCP/NCCP Implementing
Entity the option to salvage the population(s) in accordance with HCP/NCCP Conservation
Measure 3.10 (Plant Salvage when Impacts are Unavoidable) described below. Additionally,
the project proponent shall confirm with the HCP/NCCP Implementing Entity that the take

in the HCP/NCCP but are “no take” species, and avoidance is the only acceptable mitigation
measure.
Congdon’s tarplant and spiny-sepaled button-celery are not addressed in the HCP/NCCP.
For these plants, mitigation shall consist of, in order of preference, (1) avoidance, (2) salvage
and transplant as described below, or (3) off-site habitat enhancement or restoration in
consultation with CDFW.
Plant Salvage when Impacts are Unavoidable (Covered Species)
Perennial Covered Plants
Where impacts to covered plant species cannot be avoided and plants will be removed by
approved covered activities, the HCP/NCCP Implementing Entity has the option of salvaging
the covered plants. Salvage methods for perennial species shall be tested for whole
individuals, cuttings, and seeds. Salvage measures shall include the evaluation of techniques
for transplanting as well as germinating seed in garden or greenhouse and then transplanting
to suitable habitat sites in the field.
Techniques shall be tested for each species, and appropriate methods shall be identified
through research and adaptive management. Where plants are transplanted or seeds
distributed to the field they shall be located in preserves in suitable habitat to establish new
populations. Field trials shall be conducted to evaluate the efficacy of different methods and
determine the best methods to establish new populations. New populations shall be located
such that they constitute separate populations and do not become part of an existing
population of the species, as measured by the potential for genetic exchange among
individuals through pollen or propagule (e.g., seed, fruit) dispersal.
Transplanting within the preserves shall only minimally disturb existing native vegetation and
soils. Supplemental watering may be provided as necessary to increase the chances of
successful establishment, but must be removed following initial population establishment.
See also All Covered Plants, below.
Annual Covered Plants
For annual covered plants, mature seeds shall be collected from all individuals for which
impacts cannot be avoided (or if the population is large, a representative sample of
individuals). If storage is necessary, seed storage studies shall be conducted to determine
ES – EXECUTIVE SUMMARY

the best storage techniques for each species. If needed, studies shall be conducted on seed
germinated and plants grown to maturity in garden or greenhouse to propagate larger
numbers of seed. Seed propagation methods shall ensure that genetic variation is not
substantially affected by propagation (i.e., selection for plants best adapted to cultivated
conditions). Field studies shall be conducted through the Adaptive Management Program to
determine the efficacy and best approach to dispersal of seed into suitable habitat. Where
seeds are distributed to the field, they shall be located in preserves in suitable habitat to
establish new populations. If seed collection methods fail (e.g., due to excessive seed
predation by insects), alternative propagation techniques shall be necessary. See also All
Covered Plants, below.
All Covered Plants
All salvage operations shall be conducted by the HCP/NCCP Implementing Entity. To ensure
enough time to plan salvage operations, project proponents shall notify the HCP/NCCP
Implementing Entity of their schedule for removing the covered plant population.
The HCP/NCCP Implementing Entity may conduct investigations into the efficacy of
salvaging seeds from the soil seed bank for both perennial and annual species. The soil seed
bank may add to the genetic variability of the population. Covered species may be separated
from the soil though garden/greenhouse germination or other appropriate means. Topsoil
taken from impact sites shall not be distributed into preserves because of the risk of
spreading new non-native and invasive plants to preserves.
The HCP/NCCP Implementing Entity will transplant new populations such that they constitute
separate populations and do not become part of an existing population of the species, as
measured by the potential for genetic exchange among individuals through pollen or
propagule (e.g., seed, fruit) dispersal. Transplanting or seeding “receptor” sites (i.e., habitat
suitable for establishing a new population) should be carefully selected on the basis of
physical, biological, and logistical considerations (Fiedler and Laven 1996); some examples
of these are listed below:
• Historic range of the species.
• Soil type.
• Soil moisture.

MM-BIO-8: San Joaquin Kit Fox Preconstruction Surveys, Avoidance and Minimization,
and Construction Monitoring. Prior to any ground disturbance related to covered activities,
a USFWS/ CDFW-approved biologist will conduct a preconstruction survey in areas identified
in the planning surveys as supporting suitable breeding or denning habitat for San Joaquin kit
fox. The surveys will establish the presence or absence of San Joaquin kit foxes and/or
suitable dens and evaluate use by kit foxes in accordance with USFWS survey guidelines
(USFWS 1999).
Preconstruction surveys will be conducted within 30 days of ground disturbance. On the
parcel where the activity is proposed, the biologist will survey the proposed disturbance
footprint and a 250-foot radius from the perimeter of the proposed footprint to identify San
Joaquin kit foxes and/or suitable dens. Adjacent parcels under different land ownership will
not be surveyed. The status of all dens will be determined and mapped. Written results of
preconstruction surveys will be submitted to USFWS within 5 working days after survey
completion and before the start of ground disturbance. Concurrence is not required prior to
initiation of covered activities.
If San Joaquin kit foxes and/or suitable dens are identified in the survey area, the measures
described below will be implemented.
• If a San Joaquin kit fox den is discovered in the proposed development footprint,
the den will be monitored for 3 days by a USFWS/CDFW– approved biologist using
a tracking medium or an infrared beam camera to determine if the den is currently
being used.
• Unoccupied dens should be destroyed immediately to prevent subsequent use.

• If a natal or pupping den is found, USFWS and CDFW will be notified immediately.
The den will not be destroyed until the pups and adults have vacated and then only
after further consultation with USFWS and CDFW.
• If kit fox activity is observed at the den during the initial monitoring period, the den
will be monitored for an additional 5 consecutive days from the time of the first
observation to allow any resident animals to move to another den while den use is
actively discouraged. For dens other than natal or pupping dens, use of the den can
be discouraged by partially plugging the entrance with soil such that any resident
animal can easily escape. Once the den is determined to be unoccupied it may be
excavated under the direction of the biologist. Alternatively, if the animal is still
present after 5 or more consecutive days of plugging and monitoring, the den may
have to be excavated when, in the judgment of a biologist, it is temporarily vacant
(i.e., during the animal’s normal foraging activities).
If dens are identified in the survey area outside the proposed disturbance footprint, exclusion
zones around each den entrance or cluster of entrances will be demarcated. The
configuration of exclusion zones should be circular, with a radius measured outward from the
den entrance(s). No covered activities will occur within the exclusion zones. Exclusion zone
radii for potential dens will be at least 50 feet and will be demarcated with four to five flagged
stakes. Exclusion zone radii for known dens will be at least 100 feet and will be demarcated
with staking and flagging that encircles each den or cluster of dens but does not prevent
access to the den by kit fox.

CWA Section 401 Water Quality Certification, and the California Department of Fish and
Wildlife in the form of a California Fish and Game Code Section 1602 Streambed Alteration
Agreement. Such permits typically include measures to avoid and minimize or mitigate
impacts. Where avoidance of jurisdictional wetlands or waters is not feasible, replacement of
resources is required in the form of restoration or creation. The project shall seek coverage
under the East Contra Costa County Habitat Conservation Plan (HCP)/Natural Community
Conservation Plan (NCCP) for impacts to jurisdictional waters or wetlands. If neither
avoidance nor coverage under the HCP/NCCP is feasible, the County shall comply with the
requirements of the 404 permit coverage for on- or off-site mitigation, at a replacement ration
of no less than 1:1.
b. Brushy Creek Setback. Per the requirements of the HCP/NCCP and Contra Costa
County General Plan policy, a development setback of 75 feet from Brushy Creek (measured
from top of bank) is required. Note that a lesser setback (for an area less than 300 linear feet)
may be approved in consultation with the East Contra Costa Habitat Conservancy.
MM-BIO-7: Alkali Grassland Avoidance and Mitigation. A portion of the aviation
development area, adjacent to the existing facilities, includes alkali grassland. Ultimate
development of this site shall require either avoidance, or establishment of like alkali
grassland outside of the development area, which shall be made under consultation with the
East Contra Costa County Habitat Conservancy. Because this area is relatively disturbed, is
isolated from similar habitat, and is maintained on an on-going basis by airport staff, it does
not represent an exemplary patch of alkali grassland. Mitigation ratios for impacts to alkali
grassland will be determined in consultation with the East Contra Costa County Habitat
Conservancy.

disturbance related to covered activities, a U.S. Fish and Wildlife Service (USFWS)-approved
biologist will conduct a preconstruction survey in areas identified in the planning surveys as
having suitable shrimp habitat. The surveys will establish the presence or absence of covered
shrimp and/or habitat features and evaluate use by listed shrimp in accordance with modified
USFWS survey guidelines (USFWS 1996b). Project proponents are required to conduct

USFWS protocol surveys in 1 year (rather than 2) to determine presence or absence of listed
shrimp species. If covered shrimp are absent from the site, there are no further requirements
related to covered shrimp. If covered shrimp are present, the following avoidance and
minimization and construction monitoring measures are required.
To the maximum extent practicable, impacts on occupied habitat of covered shrimp will be
avoided by implementing the following measures based on existing mitigation standards
(USFWS 1996a).
• If suitable habitat for covered shrimp will be retained on site, establish a buffer
(described below) from the outer edge of all hydric vegetation associated with
seasonal wetlands occupied by covered shrimp. Alternatively, at the request of the
project proponent, representatives of the East Contra Costa County Habitat
Conservancy and USFWS may conduct site visits to inspect the particular
characteristics of specific project sites and may approve reductions of the buffer.
Buffer reductions may be approved for all or portions of the site whenever reduced
setbacks will maintain the hydrology of the seasonal wetland and achieve the same
or greater habitat values as would be achieved by the original buffer.
• Activities inconsistent with the maintenance of seasonal wetlands within the buffers
and disturbance of the on-site watershed will be prohibited. Inconsistent activities
include altering existing topography; placing new structures within the buffers;
dumping, burning, and/or burying garbage or any other wastes or fill materials;
building new roads or trails; removing or disturbing existing native vegetation;
installing storm drains; and using pesticides or other toxic chemicals.
• Filling of seasonal wetlands, if unavoidable, will be delayed until pools are dry and
samples from the top 4 inches of wetland soils are collected. Soil collection will be
sufficient to include a representative sample of plant and animal life present in the
wetland by incorporating seeds, cysts, eggs, spores, and similar inocula. The
amount of soil collected will be determined by the size of the wetland filled and the
variation in physical and biological conditions within the wetland. The number and
size of samples will be sufficient to capture this variation. For very small wetlands it
may be most cost effective to simply collect all topsoil. These samples will be

provided to the East Contra Costa County Habitat Conservancy so that the soil can
be translocated to suitable habitat within the inventory area unoccupied by covered
shrimp or used to inoculate newly created seasonal wetlands on preserve lands.
• Seasonal wetlands occupied by covered shrimp that are filled will be offset by
preserving or acquiring seasonal wetlands occupied by the covered shrimp species
and restoring habitat suitable for the covered shrimp species in accordance with
Conservation Measure 3.8. Such mitigation will supersede requirements for
mitigation of impacts on wetland habitat when covered species are present.
If suitable habitat for covered shrimp will be retained on site, project proponents will establish
a buffer from the outer edge of all hydric vegetation associated with seasonal wetlands
occupied (or assumed to be occupied) by covered shrimp. This buffer zone will be
determined in the field by the biologists as the immediate watershed feeding the seasonal
wetland or a minimum of 50 feet, whichever is greater. Buffers will be marked by brightly
colored fencing or flagging throughout the construction process. Activities will be prohibited
within this buffer in accordance with the minimization measure above.
Construction personnel will be trained to avoid affecting shrimp. A qualified biologist
approved by USFWS will inform all construction personnel about the life history of covered
shrimp, the importance of avoiding their habitat, and the terms and conditions of the
HCP/NCCP related to avoiding and minimizing impacts on covered shrimp.
MM-BIO-10. Eastern Contra Costa County Habitat Conservation Plan (HCP)/Natural
Community Conservation Plan (NCCP) Permit Coverage and Take Authorization. Prior

drainage systems or provide substantial additional
sources of polluted runoff; or (d) impede or redirect
flood flows.
MM-HYD-1: Hydrology and Drainage Study. Prior to approval of individual development
plans, a Hydrology and Drainage Study shall be prepared for the project to refine the size and
hydrologic characteristics of drainage areas that intersect the project site, to estimate pre-
and post-project flow rates and volumes under 10- 25-, 50- and 100-year storm events, and
to provide recommendations for needed improvements. The Hydrology and Drainage Study
shall quantify the capacity of the existing detention basin; determine whether or not it will be
sufficient to serve future land uses; and establish the hydrology performance criteria and
design standards applicable to potential future tenants, based on the destination of runoff
(i.e., detention basin or Bushy Creek) and the degree of impervious surface coverage. The
study shall be consistent with the hydrology performance criteria and design standards
contained within the Contra Costa County Drainage Ordinance (Division 914), which include
but are not limited to:
• Drainage facilities shall be designed to convey a minimum (with sufficient freeboard) of
the runoff produced by a) a 10-year storm event for facilities draining an area of less than
1 square mile, b) a 25-year storm event for facilities draining an area of between 1 and 4
square miles, and c) a 50-year storm event (and 100-year event without freeboard) for
facilities draining an area of more than 4 square mile.
• Finished floors shall be elevated above the base flood elevation of the one-hundred-year
frequency storm runoff, as determined using the maximum potential development of the
drainage basin or watershed shall.
• Storm flows shall be collected and conveyed in a manner that avoids damage to any
improvement, building site or dwelling which may be constructed as part of the project.
• Detention basins shall be sized to contain without freeboard a one-hundred-year average
recurrence interval runoff, unless it can be shown that a one- hundred-year average
recurrence interval runoff can be safely passed through the detention basin without
damage to the detention basin or any other property.

U.S. Army Corps of Engineers shall be obtained, per MM-BIO-6, and the Contra Costa
County Public Works Department shall be provided with drainage studies and engineering
reports sufficient to demonstrate that flood flows on Brushy Creek would not be impeded or
redirected. For all development planned within the FEMA 100-year floodplain, subject to
approval of the Contra Costa County Public Works Department, the developer would be
required to file a Conditional Letter of Map Revision to process the change and shall obtain a
FEMA modification of the SFHA as shown on the Flood Insurance Rate Map.

Transportation and Traffic
Impact 3.13-2. The project would potentially conflict or
be inconsistent with CEQA Guidelines Section
15064.3(b).
MM-TRAF-1: Project Site Design. The project shall provide site design features that
facilitate pedestrian amenities and promote accessibility for on-site pedestrian movement and
connectivity to various buildings or project components. As shown Table 3.13-10, this
measure would result in a range of reduction in VMT.
MM-TRAF-2: Bicycling Facilities. The project shall provide adequate bike parking, change,
and shower facilities on-site and improve accessibility for on-site bicycle movement as well as
connections to immediate proposed off-site bike lanes along Byron Hot Springs Road and
Holey Road. As shown in Table 3.13-10, this measure would result in a 0.63% reduction in
VMT. Low stress bikeway proposed along Byron Highway can be made accessible to
bicyclists from the project if bike routes can be planned along Holey Road and Byron Hot
Springs Road.
MM-TRAF-3: Access to Transit and Expansion of Transit Network. The project shall
provide access to transit and expand transit network. The project should work with Tri Delta
Transit to add transit service in the project vicinity and provide connections with the cities of
Antioch, Brentwood, Pittsburg and Oakley and other unincorporated areas. As shown Table
3.13-10, this measure was assumed to result in a conservative 0.1% reduction in VMT since
there are no known transit service improvement or expansion projects near the project site.
However, once transit coverage is increased, this VMT reduction could increase, however it
would not reduce the Project’s VMT to a less than significant level.
MM-TRAF-4: Ridesharing and Car-Sharing Programs for Employees. The project shall
provide/promote/subsidize ride-sharing programs to the employees by utilizing approaches
such as designating a certain percentage of parking spaces for ride sharing vehicles,
designating adequate passenger loading/unloading and waiting areas for ride-sharing
vehicles, and providing a website or message boards for coordinating rides. Increasing the
vehicle occupancy by utilizing ride sharing will result in fewer cars driving the same trip,
thereby decreasing the VMT. As shown in Table 3.13-10, providing ridesharing and car-
sharing programs to approximately 50% of the employees would result in a 2.5% and 0.4%
reduction in VMT.

MM-TRAF-5: Employer-Sponsored Vanpool/Shuttle. The project shall provide an
employer-sponsored vanpool and shuttle for use by employees for commutes to work, and
bus/transit station. The vanpool and shuttle will be available to all employees; however, the
calculations conservatively assume the program would be offered to/utilized by 50 percent of
employees. As shown in Table 3.13-10, providing employer-sponsored vanpool/shuttle to
approximately 50% of the employees, would result in a 6.7% reduction in VMT.
MM-TRAF-6: Encourage Telecommuting and Alternative Work Schedules for
Employees. According to CAPCOA, encouraging telecommuting and alternative work
schedules would reduce the number of commute trips, thereby reducing the project’s VMT.
Staggered start times, flexible schedules, or compressed work weeks are examples of
alternative work schedules. Because retail and industrial/warehouse operations may require
most of the employees to be on-site 24-hours per day, alternative work schedules may be
feasible for a majority of the employees. The project shall implement a 4-day/40-hour work
schedule for approximately 25% of the employees. As shown in Table 3.13-10, with 25%
employee participation in an alternate work schedule consisting of a 4-day/40- hour work
week, a VMT reduction of 3.75% would result.
MM-TRA-7: Implement Commute Trip Reduction Marketing. The project shall implement
marketing strategies to reduce commute trips. The marketing strategies would include new
employee orientation of trip reduction and alternative mode options, event promotions and
publications. Although the marketing would target all employees, a conservative assumption
of marketing to only 50 percent of the employees was utilized in the calculation. As shown in
Table 3.13-10, implementing/promoting commute trip reduction marketing to approximately
50% of the employees, would result in a 2.0% reduction in VMT.
MM-TRAF-8: Implement Subsidized or Discounted Transit Program for Employees. The
project shall provide subsidized or discounted daily or monthly public transit passes to the
employees. Although subsidized or discounted transit program would be available to all
employees, the VMT reduction calculation conservatively assumes that the program would be
available to and utilized by a maximum of 50% of employees. As shown in Table 3.13-10,
implementing subsidized or discounted transit program to approximately 50% of the
employees, would result in a 1.0% reduction in VMT.

ES.3 ANALYSIS OF ALTERNATIVES
ES.3.1 Alternatives Considered
Three alternatives to the proposed project, including the No Project/Aviation Only Alternative,
were considered in Chapter 4, Alternatives. The No Project Alternative is a required element of an
EIR pursuant to Section 15126.6(e) of the CEQA Guidelines that examines the environmental
effects that would occur if the project were not to proceed. The other alternatives are discussed as
part of the “range of reasonable alternatives” selected by the County. The alternatives addressed
in Chapter 4 are listed below, followed by a description of each:
• No Project/Aviation Only Alternative: This alternative assumes that 167 aircraft would be
based at the airport within 10 years (compared to the current estimate of 105). Airport
storage, including hangars and tie-downs, would be constructed to accommodate additional
aircraft. New structures would be limited to 20,000 to 40,000 square feet due to limitations
in water, sewer, and stormwater infrastructure. Development would occur on the “aviation
reserve” site south of the main runway, as identified in the Project Description. No
development would occur in the non-aviation area east of the main runway. Acquisition of
the residence in the northeast corner of the project site would not occur.
• Aviation Expansion: Under this Alternative, 11.8 acres would be dedicated to future
airport storage (including hangars and tie downs). Up to 154,000 square feet of aviation
related buildings would be constructed, within a project area of 11.8 acres. No development
would occur in the non-aviation area east of the main runway. Acquisition of the residence
in the northeast corner of the project site would not occur.
• Reduced Intensity: The development footprint under the Reduced Intensity Alternative
would be similar to the proposed project, but the intensity would be reduced. The floor-to-
area ratio of logistics/warehouse/distribution would be reduced to 0.25 (from 0.30 in the
proposed project). Office and commercial development would be eliminated and the
potential acreage for those uses would be used for logistics/warehouse/distribution. The
11.7-acre parcel adjacent to the non-aviation development would not be acquired. The
development scenario is shown in the Table ES-2, below.

Total building area would be reduced to 723,000 square feet, as opposed to the proposed project
amount of 941,000 square feet. Total employees and visitors would not exceed 636 at any given
time, as opposed to 1,528 for the proposed project.
ES.3.2 Environmentally Superior Alternative
The No Project/Aviation Only Alternative would result in the least environmental impacts and
would be the environmentally superior alternative. However, none of the project objectives would
be achieved by the No Project/Aviation Only Alternative. Section 15126.6(e)(2) of the CEQA
Guidelines states that if the environmentally superior alternative is the No Project Alternative, the
EIR shall also identify an environmentally superior alternative among the other alternatives. In
this case, the environmentally superior alternative is the Aviation Expansion Alternative, which
would reduce potentially significant impacts related to greenhouse gas emissions and traffic and
circulation. By reducing the number of truck traffic, vendors, employees and visitors, the Aviation
Expansion Alternative would reduce impacts related to transportation, GHG emissions, and noise.
This alternative would achieve the aviation-related objectives of the project, but would not achieve
objectives related to economic development and financial self-sufficiency.
ES.4 AREAS OF CONTROVERSY
Section 15123 (b)(2) of the CEQA Guidelines requires the executive summary of an EIR to
disclose areas of controversy known to the lead agency that have been raised by the agencies and
the public. The County circulated a Notice of Preparation (NOP) to solicit agency and public
comments on the scope and environmental analysis to be included in the EIR. A total of three
comment letters were received during the NOP public review period. Copies of the NOP and the
NOP comment letters received by the County are included in Appendix A to this EIR. The
following issues were raised in the written responses to the NOP:

ES.5 ISSUES TO BE RESOLVED BY LEAD AGENCY
Section 15123(b)(3) of the CEQA Guidelines requires that an EIR contain a discussion of issues
to be resolved. With respect to the proposed project, the key issues to be resolved include decisions
by the County, as lead agency, as to:
Selection of proposed project or feasible project alternatives.
Feasibility of the recommended mitigation measures.
Whether or not to proceed with the proposed project.

CHAPTER 1
INTRODUCTION
1.1 PURPOSE AND INTENDED USE OF THIS EIR
Contra Costa County (County) has prepared this Draft Final Environmental Impact Report (EIR)
to inform the community, responsible agencies, trustee agencies, and other interested agencies and
organizations of the potential significant environmental effects resulting from implementation of
the proposed Byron Airport Development Program (project) and the mitigation measures or project
alternatives that would avoid or substantially reduce those effects. This Draft EIR was prepared in
compliance with the California Environmental Quality Act (CEQA) (California Public Resources
Code, Section 21000 et seq.) and the CEQA Guidelines (14 CCR 15000 et seq.).1
As described in CEQA Guidelines Section 15121(a), an EIR is an informational document that
assesses the potential environmental impacts of a proposed project and identifies mitigation
measures and alternatives to a proposed project that could reduce or avoid adverse environmental
impacts. As the CEQA lead agency for this project, the County is required to consider the
information in the EIR along with any other available information in deciding whether to approve
the project. The basic requirements for an EIR include providing information that establishes the
environmental setting (or project baseline) and identifying environmental impacts, mitigation
measures, project alternatives, growth-inducing impacts, and cumulative impacts. In a practical
sense, an EIR functions as a method of fact finding, allowing an applicant, the public, other public
agencies, and agency staff an opportunity to collectively review and evaluate baseline conditions
and project impacts through a process of full disclosure. Additionally, this EIR represents the
primary source of environmental information for the lead agency to consider when exercising any
permitting authority or approval power directly related to implementation of this project. It is not
the intent of an EIR to recommend either approval or denial of a project.
This Draft EIR is a Program EIR, pursuant to CEQA Guidelines Section 15168. A Program EIR
examines the environmental impacts of a series of actions that can be characterized as one large
project. In this instance, there are multiple individual projects that may be approved by the County
in the further development of Byron Airport. However, it is the intent of this program EIR to
describe the project site and the potential development in sufficient detail that subsequent activities
can be found to be within the scope of this Program EIR, and no additional environmental
1 The California Resources Agency, in conjunction with the Governor’s Office of Planning and Research, recently
prepared the 2018 Update to the CEQA Guidelines. The amended guidelines were approved by the Office of
Administrative Law on December 28, 2019. Per Section 15007(d), a lead agency shall comply with new
requirements in amendments to the guidelines no later than the 120th day after the effective date of the
amendments, unless the lead agency amends their local procedures to comply earlier. Per Section 15007(c), a
document sent out for public review shall conform to the guidelines in effect at this time. Therefore, this Draft
EIR reflects the amendments approved on December 28, 2018.

documents need be prepared, per Section 15168(c)(5). Please see Chapter 2, Project Description,
for information on the development program and the anticipated subsequent activities.
1.2 PROJECT BACKGROUND AND OVERVIEW
The original Byron Airport Master Plan (Airport Master Plan) was adopted in 1986, and the airport
was opened in 1994. The Airport Master Plan was updated in 2005 and identifies a 20-year plan
to support aviation activities at the airport. The 2005 Airport Master Plan also identifies potential
development opportunities on airport property to increase airport revenue and achieve economic
self-sufficiency.
In 2015, the County identified a suite of proposed land uses for development on airport property,
building on the framework of the 2005 Airport Master Plan. The uses included aviation reserve
land uses, which would be directly associated with aircraft operations (e.g., hangar development,
aircraft repair and maintenance), and aviation-related land uses, which would not be aeronautical
uses but would be compatible with on-going aircraft operations (i.e., aviation-compatible uses).
Examples of aviation-compatible uses include warehouse use and light industry.
The County’s current General Plan policies, zoning regulations, and airport land use compatibility
plan policies specific to the airport would not accommodate many of the proposed land uses.
Therefore, the County’s Department of Conservation and Development, Department of Public
Works, and Airports Division are working collaboratively to amend the General Plan, Zoning
Code, and Airport Land Use Compatibility Plan to enable on-site development in accordance with
the proposed Airport Master Plan. Ultimately, the Byron Airport Planned Unit District (P-1)
identified in the Zoning Code will be amended to identify additional aviation-reserve uses and
aviation-compatible uses that would be permitted by right.
The project would provide for both aviation development and non-aviation (airport-related)
development. Aviation uses include aircraft storage, administrative facilities, instructional
facilities, fixed base operators, pilot and passenger terminal improvements, cargo facilities, and
aircraft repair and service. Non-aviation development includes a wide range of industrial,
commercial, and office uses that benefit from proximity to the airport and the regional roadway
network. These uses may include warehousing and distribution; light manufacturing; research and
development; regional retail, including construction materials and home goods; service
commercial; and offices. Local retail and food service may also be provided to serve the airport
and local residents.

it was determined that the project would have no potential for significant environmental effects.
This is further discussed in Chapter 5, Other CEQA Considerations.
This EIR evaluates the direct impacts, reasonably foreseeable indirect impacts, and cumulative
impacts resulting from planning, construction, and operation of the proposed project using the
most current information available and in accordance with the provisions set forth in CEQA and
the CEQA Guidelines. In addition, the EIR recommends potentially feasible mitigation measures,
where possible, and project alternatives that would reduce or eliminate significant adverse
environmental effects.
The alternatives chapter of this EIR (Chapter 4, Alternatives) was prepared in accordance with
Section 15126.6 of the CEQA Guidelines. CEQA requires that the lead agency adopt mitigation
measures or alternatives, where feasible, to substantially lessen or avoid significant environmental
impacts that would otherwise occur. Project modification or alternatives are not required, however,
where significant environmental impacts would not occur.

CHAPTER 2
PROJECT DESCRIPTION
2.1 PROJECT BACKGROUND AND OVERVIEW
Studies carried out in the late 1970s and early 1980s identified the need for one or more airports
in Contra Costa County (County) to relieve the aircraft parking and operational pressures on
Buchanan Field Airport in Concord, California. Continued urbanization in the western and central
sections of the county made it impossible to develop a new airport in those areas.
The County focused its attention on finding a site for a new airport in the less-populated eastern
portion of the county. A site evaluation led the County Board of Supervisors to select Byron
Airpark to provide aviation facilities for the residents in the eastern part of the County. An Airport
Master Plan and Environmental Impact Report (EIR) were adopted in 1986. The intent of the
Airport Master Plan was to guide development of the airport over a 20-year planning period. Byron
Airpark was purchased in 1986 and a new airfield was constructed in the early 1990s. Byron
Airport opened to the public in 1994.
In 2005, the County adopted an updated Byron Airport Master Plan. In keeping with Federal
Aviation Administration guidelines, the 2005 Airport Master Plan involves a 20-year planning
period, with 2003 as the base year. Individual airport improvement recommendations are oriented
to 5- (2008), 10- (2013), and 20-year (2023) planning horizons (Contra Costa County 2005a).
The 2005 Airport Master Plan identifies several potential development areas within the airport’s
boundary. Existing aircraft storage and parking occupies approximately 20 acres on the south side
of the main runway. The 2005 Airport Master Plan identifies 35 acres for future aviation uses,
generally located west of the intersection of the two runways, which is reserved for uses directly
associated with the function of the airport, such as a terminal, hangars, fixed-base operator, aircraft
maintenance, fueling facilities, and administrative offices. Approximately 86 acres is designated
for non-aviation (airport-related) uses and is generally located east of the runways. This area is
planned for airport compatible uses, such as light industry. This area may include leases to private
entities, thereby providing a revenue stream for the airport. The remaining development area,
approximately 30 acres, is reserved for low-intensity uses, including infrastructure and/or
protection of the airfield. The 2005 Airport Master Plan identifies 814 acres as a biologically
sensitive area for habitat management (Contra Costa County 2005a).
The County identified a range of potential land uses that could be developed in the aviation and
non-aviation areas, including commercial and industrial land uses. Many of these land uses (those
not directly related to aviation activities) are not compatible with the current zoning or General
Plan designation. In addition, development of these land uses is constrained by the current Airport
Land Use Compatibility Plan (ALUCP) (Contra Costa County 2000). The County proposes to
2 – PROJECT DESCRIPTION
Byron Airport Development Program EIR 9269
February 2022 2-2
update the zoning for the airport property and associated General Plan policies. The update of the
ALUCP must be approved by the Contra Costa County Airport Land Use Commission, which
must then determine that the updated zoning ordinance and General Plan are consistent with the
approved ALUCP update.
As part of this process, the County refined the proposed development areas on the airport property
at this time, eliminating 11 acres of aviation development north of the crosswind runway and
approximately 40 acres of non-aviation development east of the runways. An isolated 10.4 acres
designated for non-aviation development on Armstrong Road was also eliminated from the
proposed development area. The proposed development area is discussed further in Section 2.6,
Proposed Land Use and Zoning.
2.2 PROJECT LOCATION
Byron Airport is located in southeastern Contra Costa County (Figure 2-1, Project Location). The
airport property consists of 1,427 acres, including 1,307 acres south of Armstrong Road and 120
acres north of Armstrong Road. The center of the main runway is located at latitude 37°49'52'' N
and longitude 121°37'34'' W. The proposed Byron Airport Development Program (project) site
excludes the 120 acres north of Armstrong Road but includes an 11.7-acre parcel located next to
the northwest corner of the airport (Figure 2-2, Project Site).
2.2.1 Setting
Byron Airport is located on the western edge of the flat Sacramento–San Joaquin Delta agricultural
lands, giving way to rolling hills and grasslands west of the airport. Byron Hot Springs, a now
abandoned resort and former World War II prisoner-of-war camp, is located north of the airport.
Several rural residential uses are on the east and west sides of the airport. Nearby unincorporated
communities include Byron, approximately 2.5 miles north; Discovery Bay 4 miles to the
northeast; and Mountain House, approximately 4 miles southeast. Clifton Court Forebay is located
less than 2 miles east, Bethany Reservoir is approximately 3 miles south, and Los Vaqueros
Reservoir is 5 miles west of the project site.
2.2.2 Project Site
The project site consists of the approximately 1,307-acre Byron Airport property south of
Armstrong Road, and the 11.7-acre parcel located between the airport property and the Bethany
Irrigation District Canal, for a total of 1,319 acres. Byron Airport also owns an additional 120 acres
north of Armstrong Road that is not part of the project site. The airport reference elevation (the
highest point of the main runway) is 78.5 feet above mean sea level (AMSL). The project site
elevation varies between 30 to 100 feet AMSL. The project site includes the existing airport
facilities and areas proposed for development (referred to as the development area). Most of the
2 – PROJECT DESCRIPTION
Byron Airport Development Program EIR 9269
February 2022 2-3
project site is reserved for habitat management. See Section 2.6 below for a description of the
project site land uses.
Byron Airport has two nonintersecting runways, each with a parallel taxiway and several connector
taxiways. General aviation facilities are generally concentrated in the west-facing “V” formed by
the two runways and include aircraft surface storage, runway apron, hangars, and office space (see
Figure 2-2). The majority of these facilities were constructed when the airport was built in the
early 1990s.
Existing Airport Facilities and Structures
The primary runway, Runway 12-30 (northwest–southeast), is 4,500 feet long and 100 feet wide.
The crosswind runway, Runway 5-23, is 3,000 feet long and 75 feet wide. Both runways have 20-
foot-wide unpaved shoulders on both sides of the runways. Byron Airport can accommodate
aircraft with wingspans of up to (but not including) 79 feet, and approach speeds of up to (but not
including) 121 knots, and meets the Federal Aviation Administration’s Air Reference Code criteria
for all aircraft currently using the airport. The runways are equipped with runway lighting, and
Runway 12-30 is also equipped with runway end-identifier lights.
There are three taxiways. Two are parallel to the runways, and the third connects the aircraft
parking apron to the other two taxiways. The aircraft parking apron is approximately 4 acres.
Byron Airport does not have a control tower. Buildings include the 2,400-square-foot
administration building (500 Eagle Court) and a 7,500-square-foot maintenance hangar (505 Eagle
Court). The administration building is served by 18 parking spaces. A fuel farm is located southeast
of the maintenance hangar. Accessory structures include a 300-square-foot pump house for fire
protection, east of the intersection of the two runways. A small building on the north side of the
airport (6900 Falcon Way) was part of the original Byron Airpark and is currently leased to Bay
Area Sky Diving.
Hangars are arranged in rows, starting northwest of the administration building. There is a 28-unit
T-hangar constructed in 1996, two rows of portable T-hangars (39 units), and two executive
hangars (10 and 12 units). The Byron Jet Center (760 Osprey Court) is located northwest of the
executive hangars. Tie downs for based aircraft and transient aircraft are located between the
hangars and the taxiways. A wash rack is located at the east side of the executive hangar row.
Wastewater from the wash rack drains though an oil–water separator to a leach field located to the
east, between the wash rack and Taxiway A.

February 2022 2-4
Utilities
Electrical power is supplied by Pacific Gas & Electric Company via Holey Road. There is no
natural gas service at the airport. The water system consists of a domestic well with a 4,000-gallon
holding tank, booster pump, and chlorinator. The on-site water supply is non-potable. Drinking
water is provided by bottled water deliveries to the airport. The sewer system consists of a 3,000-
gallon septic tank and lift station that pumps to a leach field located southwest of the aircraft apron.
Telephone service is provided by SBC Communications.
2.3 PROJECT OBJECTIVES
Pursuant to California Environmental Quality Act (CEQA) Guidelines Section 15124(b), the
project description must include a clear statement of project objectives. The County has identified
the following project objectives:
• Develop airport facilities to support the types of development envisioned in the Airport
Master Plan and subsequent airport planning efforts.
• Achieve economic self-sufficiency of the airport through the development of airport-
related land uses.
• Protect current and future airport operations from incompatible land uses.
• Provide a streamlined planning framework for future development consistent with the
General Plan and the ALUCP.
2.4 PROPOSED AIRPORT LAND USE PLAN UPDATE
Every county in California that contains at least one public airport must prepare an Airport Land
Use Plan (also known as an Airport Land Use Compatibility Plan), per the State Aeronautics Act
(Public Utilities Code Section 21001 et seq.). The purpose of ALUCPs is to minimize the public’s
exposure to excessive noise and safety hazards while providing for the orderly expansion of
airports. ALUCPs achieve this by identifying land use types and intensities that are compatible
with four key factors: safety, noise, airspace protection, and overflight. The California Department
of Transportation (Caltrans), Division of Aeronautics, provides guidance on airport land use
planning in its California Airport Land Use Planning Handbook (Caltrans 2011).
The ALUCP for Byron Airport was adopted in 2000, with minor modifications in 2006 and 2016
(Contra Costa County 2000). The current ALUCP reflects the original 1986 Airport Master Plan
for the East Contra Costa County Airport (now Byron Airport). The Byron Airport Master Plan
was updated in 2005 (Contra Costa County 2005a). In addition, the Airport Layout Plan—required
by the Federal Aviation Administration and a main component of the Airport Master Plan—was
updated in 2016 (Contra Costa County 2016). The standards used in the current ALUCP for Byron
2 – PROJECT DESCRIPTION
Byron Airport Development Program EIR 9269
February 2022 2-5
Airport are based on the 1993 edition of the Airport Land Use Planning Handbook. Caltrans has
updated this guidance document twice since that time, in 2002 and 2011 (Caltrans 2011). Thus,
the current ALUCP for Byron Airport does not reflect the latest planning and forecasts for the
airport, and is based on dated compatibility planning guidance. The Airport Layout Plan was
updated in 2016, and this is not reflected in the current ALUCP for Byron Airport. The effect is
an ALUCP that does not allow the type of development envisioned in the Airport Master Plan,
which would provide for the economic development and fiscal self-sufficiency of Byron Airport.
The proposed ALUCP update for Byron Airport would revise the policies for Byron Airport,
consistent with current Caltrans California Airport Land Use Planning Handbook and the policy
framework in effect at Buchanan Airport (Contra Costa County 2000). The Countywide policies
in the ALUCP for Byron Airport would not change. Key changes for Byron Airport policies are
described below by category: safety, noise, airspace protection, and overflight.
Safety
Several important changes would be made to Byron Airport’s safety policies. These are driven
primarily by applying the latest Caltrans guidance to the airport. The current ALUCP for Byron
Airport uses six “composite” zones known as zones A, B1, B2, C1, C2, and D. These zones
combine noise and safety criteria to determine compatible land uses (Contra Costa County 2000).
The proposed ALUCP update would identify six safety zones (1 through 6) consistent with the
current Airport Land Use Planning Handbook. By using more carefully defined safety zones and
by addressing noise compatibility separately, a greater range of development types would be
allowed. In addition, applying current Airport Land Use Planning Handbook standards for non-
residential development would increase the level of development that would be allowed, and
thereby support the County’s goals for economic development at the airport.
Noise
The proposed ALUCP update for Byron Airport would separate the noise criteria from the safety
criteria when determining compatible use. Noise compatibility is based on noise contours
developed from forecasted aviation activity. The aviation forecasts for the airport remain valid and
would not be revised as part of the proposed ALUCP update. Therefore, the noise contours would
not change. The commercial and light industrial uses planned for the airport are not considered to
be noise-sensitive uses. Therefore, separating the noise criteria from the safety zones would
increase the range and intensity of non-residential land uses.
Airspace Protection
Airspace protection policies regulate development that may interfere with the safe navigation of
aircraft, including physical structures or potential hazards such as dust, smoke, light/glare, and
2 – PROJECT DESCRIPTION
Byron Airport Development Program EIR 9269
February 2022 2-6
wildlife. Minor changes would be made to airspace policies to reflect the 2016 Airport Layout
Plan, including runway approach profiles. However, no significant changes would be made to the
policies, and there would be no effect on allowable land uses.
Overflight
Overflight policies do not regulate land use but identify the areas subject to noise from overflight
(as compared to noise from aircraft approaches and departures). The overflight area, along with
airspace protection, discussed above, helps to define the airport influence area. The airport
influence area includes a notification area (the area where home buyers must be notified of the
presence of the airport), which is related to overflight. Overflight policies also identify areas where
avigation easements (dedicating airspace rights to the airport) should be acquired. The notification
area would be slightly larger in the proposed ALUCP update for Byron Airport to reflect the 2016
Airport Layout Plan, but there would be no change to policies that would affect allowable land
uses or future development.
2.5 GENERAL PLAN AMENDMENT
The County General Plan designates the existing aviation facilities and the master-planned
development areas as Public/Semi-Public (PS). The remainder of the airport property is designated
as Open Space (consistent with the habitat management use for the non-developable airport
property) (Contra Costa County 2017). The General Plan designation for the existing airport
property will not change. The 11.7-acre acquisition parcel would be redesignated from
Agricultural Lands to PS.
General Plan Policy 5-66 states, “Establishment of commercial, industrial or residential development
around the planned airport shall not be allowed” (Contra Costa County 2005b). This policy would be
amended to specify that commercial or industrial development would be allowed on airport property
if it is consistent with the ALUCP and the Airport Master Plan for Byron Airport.
Policy 5-77 would be updated to reflect the new compatibility zone designations (Zone B-1 would
become Safety Zone 2) and the additional uses at the airport that may be found compatible under
the updated ALUCP for Byron Airport.
2.6 PROPOSED LAND USES AND ZONING
The airport property is currently zoned Planned Unit District (P-1) (Contra Costa County 2005c).
The P-1 zoning is intended to allow diversification in the relationship of various uses, buildings,
structures, lot sizes, and open space areas while ensuring substantial compliance with the General
Plan and the intent of the County Code in requiring adequate standards necessary to satisfy the
2 – PROJECT DESCRIPTION
Byron Airport Development Program EIR 9269
February 2022 2-7
requirements of public health, safety, and general welfare. Currently, the Byron Airport P-1 zoning
only allows aviation-related uses, agriculture, and open space.
The amended Planned Unit District will identify four separate development areas: Aviation,
Airport Related, Low-Intensity Use, and Habitat Management. These zones are further described
below and are shown in Figure 2-3, Development Area and Safety Zones (which includes an
overlay of the proposed ALUCP safety zones). The most important change would be to the airport-
related uses, which would allow non-residential development that is compatible with the ALUCP
for Byron Airport. These uses would include light industry, warehousing and logistics,
commercial, and low-intensity office.
In addition, the 11.7-acre parcel to be acquired by the County would be rezoned from Agriculture
(A-3) to P-1.
Aviation
A total of 23.5 acres is designated for aviation uses, located adjacent to the taxiways and runways. The
aviation area is adjacent to a developed 10.5-acre aircraft storage area and 9.7-acre aircraft parking
area south of the main runway (Runway 12-30). Proposed land uses in the aviation area include airport
infrastructure (e.g., control tower, terminals), hangars, fixed-base operators, businesses that directly
support aviation and travel (e.g., aircraft service and fuel, rental car facilities, pilots lounge, meeting
facilities), and businesses that directly rely on aviation (e.g., agricultural aviation, aerial surveys and
photography, air charter businesses, air cargo, just-in-time delivery).
Non-Aviation (Airport Related)
Approximately 46.6 acres of Byron Airport is designated for non-aviation. This includes 34.9 acres
east of the main runway on the existing airport property, and 11.7 acres in the adjacent parcel.1
The 46.6 acres would support commercial and light-industrial uses that are compatible with airport
operations and would benefit from being located at an airport, with access to Highway 4, Interstate
205, and Interstate 580. A variety of retail, service, warehouse and distribution, light
manufacturing, and low-density office uses would be allowed.
Low-Intensity Use
The areas adjacent to the ends of the primary runway and within the “no build” area adjacent to
the runway, approximately 31 acres, are designated as low-intensity use. No structures would be
allowed within this area. Infrastructure improvements may be allowed within this area.
1 As shown in Figure 2-3, the total development area east of the main runway is 51.6 acres. However, 5 acres are
constrained for stormwater infrastructure, for a net of 4 6.6 acres.
2 – PROJECT DESCRIPTION
Byron Airport Development Program EIR 9269
February 2022 2-8
Habitat Management Lands
The majority of the project site, approximately 814 acres, is owned and managed by the County
as wildlife habitat, consistent with the East Contra Costa County Habitat Conservation Plan
(ECCC HCP 2006).2 The proposed project does not propose changes to habitat management lands.
Development Reserve
As noted above, the 2005 Airport Master Plan identified a potential development area larger than
the one currently under consideration. The areas that have been removed from the aviation and
non-aviation development area are identified as “development reserve” in Figure 2-3. There are
no land uses assigned to this category, it merely denotes an area that was previously identified for
potential development in the 2005 Airport Master Plan, but is no longer considered part of the
proposed development program.
Development Scenario
Taking into account the land use areas described above and the proposed safety zones (see Section
2.4, Proposed Airport Land Use Plan Update), a preferred development scenario was developed.
This scenario represents a reasonable distribution of compatible land uses on the airport property
and forms the basis of the impacts analysis in Chapter 3, Environmental Setting and Impacts. The
development scenario, presented in Table 2-1, assigns a percentage of available acreage to the
various uses (e.g., light industry), and estimates the potential building area as increments of 1,000
square feet for those uses based on floor-to-area ratio. The number of people who may the site at
any given time was then calculated using intensity factors from the Airport Land Use Planning
Handbook and the County’s General Plan.

2.8 FUTURE DEVELOPMENT AND ENVIRONMENTAL REVIEW
This Program EIR prepared for the General Plan Amendment, Zoning Amendment, and ALUCP
update is intended to streamline future development at Byron Airport. The County Airports
Division retains discretion over all new development at Byron Airport, and reviews subsequent
projects for consistency with the ALUCP and the Airport Master Plan. Certain non-aviation
development proposals may also be reviewed by the Department of Conservation and
Development. It is intended that this Program EIR would provide the basis for approval of those
land uses permitted in the Planned Unit District. Per CEQA Guidelines Section 15168(c)(2), a
subsequent project that is consistent with the use, overall building intensity, and geographic area
analyzed in a Program EIR may be found to be within the scope of that EIR, and no new
environmental document would be required. If a subsequent project would, due to the nature of
the project or its location, potentially result in impacts that were not addressed in the Program EIR
as significant, or would be substantially greater than those identified in the Program EIR, a tiered
CEQA document may be prepared, per CEQA Guidelines Section 15152, based on the Program
EIR. A subsequent tiered document should analyze only those project or site-specific issues that
were not addressed in the Program EIR. The “Development Scenario” presented in Section 2.6,
Proposed Land Uses and Zoning, is not meant to be a regulatory limit on the types or distribution
of allowed development, but to provide a reasonably foreseeable project condition and to assist
the County in determining if subsequent implementing projects would be adequately addressed by
this Program EIR.

CHAPTER 3
ENVIRONMENTAL SETTING AND IMPACTS
Chapter 3 discusses the environmental resources potentially impacted by the proposed Byron
Airport Development Program (project). Each resource section includes an environmental and
regulatory setting, the standards of significance, the potential project impacts (e.g., direct, indirect,
and cumulative impacts), and mitigation measures that would avoid or substantially reduce
potentially significant impacts. To the extent that mitigation measures would themselves result in
secondary impacts, those impacts are discussed, although not at the level of detail required for
project impacts.
3.0 ENVIRONMENTAL SETTING
3.0.1 Project Baseline
According to Section 15125(a) of the California Environmental Quality Act (CEQA) Guidelines,
an Environmental Impact Report (EIR) must include a description of the existing physical
environmental conditions in the vicinity of the project as they exist at the time when the Notice of
Preparation was published. This “environmental setting” will normally constitute the “baseline
condition” against which project-related impacts are compared. Therefore, the baseline conditions
for this Draft Final EIR, unless noted otherwise, are based on conditions that existed in September
2017, when the Notice of Preparation was published. The exact date of baseline information may
vary based on the availability of data and the timing of certain studies. CEQA follows a rule of
reason regarding data collection, and to the extent feasible, data will reflect conditions closest to
September 2017 for the proposed project.
3.0.2 Cumulative Setting
CEQA requires that an EIR assess the cumulative effects that could be associated with the
incremental effects of a proposed project. Cumulative effects are defined as two or more individual
effects that, when considered together are considerable or that would compound or increase other
environmental effects. The cumulative impact of a project results from the incremental impact of the
project when added to other closely related past, present, and reasonably foreseeable future projects.
As indicated in the CEQA Guidelines, the discussion of cumulative impacts need not provide the
same level of detail as project-related impacts. The discussion should be guided by “standards of
practicality and reasonableness” (CEQA Guidelines, Section 15130[b]). Although project-related
impacts can be individually minor, the cumulative effects of these impacts, in combination with the
impacts of other projects, could be significant under CEQA and must be addressed (14 CCR
15130[a]). Where a lead agency concludes that the cumulative environmental impacts of a project,
taken together with the impacts of other closely related past, present, and reasonably foreseeable
probable future projects are significant, the lead agency then must determine whether the proposed
3.0 – ENVIRONMENTAL SETTING AND IMPACTS
Byron Airport Development Program EIR 9269
February 2022 3-2
project’s incremental contribution to such significant cumulative impacts is “cumulatively
considerable” (and thus significant in and of itself).
Cumulative Context
To ensure that an adequate discussion of cumulative impacts is included in an EIR, CEQA allows
the lead agency to use one of two methods. The first method consists of a list of past, present, and
probable future projects, including those projects outside of the control of the lead agency. The
second method consists of projections included in adopted local, regional, and/or statewide plans,
such as a General Plan (CEQA Guidelines Section 15130[b][1]). There are no currently proposed
projects in the immediate project vicinity. In fact, as an airport, the location of
Byron Airport is surrounded by agricultural land and scattered rural and light industrial
development, and not urban development. Therefore, this EIR relies upon the projection method
from adopted plans. The Contra Costa County General Plan 2005–2020 is relied upon as the overall
source for future development, but individual resource areas may rely upon other projections. For
example, the cumulative traffic analysis relies upon estimates of regional traffic growth from the
Contra Costa Countywide Travel Demand Model.
The geographic setting of cumulative impacts may also vary with the resource. Cumulative air
impacts related to criteria air pollutants, for example, consider the entire air basin for a regional
context. Aesthetic impacts consider the viewshed that includes the project site, and water quality
and hydrology consider the entire water basin. Each impact section discusses the method and
geography used to assess cumulative impacts (see Sections 3.1 through 3.15).
Since the publication of the NOP, the Costa Water District has approved the Phase 2 Expansion of
the Los Vaqueros Reservoir, which will increase the capacity of the existing reservoir to 275 TAF
and, among other conveyance facilities, will construct the Transfer-Bethany Pipeline. The
approximately 8-mile pipeline would connect the Los Vaqueros Transfer Facility (located between
Camino Diablo and Vasco Road, northeast of the Los Vaqueros Reservoir) to the California
Aqueduct (north of Bethany Reservoir). The proposed alignment is identified in the 2020 Final
Supplement to the EIS/EIR for the Los Vaqueros Expansion Project (State Clearinghouse No.
2006012037). The proposed alignment would parallel Vasco Road and follow Armstrong Road
along the west edge of Byron Airport, past the southerly property line of the Airport, before turning
east and then south to connect to the California Aqueduct.

3.1 AESTHETICS
This section describes the existing visual setting of the project site and vicinity, identifies
associated regulatory requirements, evaluates potential impacts, and identifies mitigation measures
related to implementation of the proposed Byron Airport Development Program (project).
3.1.1 Existing Conditions
3.1.1.1 Overview
The project site is located in southeastern Contra Costa County (County), approximately 2.5 miles
south of the community of Byron. The County General Plan recognizes scenic ridges, hillsides,
rock outcroppings and the San Francisco Bay/Delta estuary system as important scenic resources
within the County (Contra Costa County 2005a). The County General Plan designates scenic
ridgelines that contribute to the rural feeling of the County’s communities and provide a scenic
backdrop for the County’s developed areas. The nearest County-designated scenic ridgeway is
approximately 7.2 miles west of the project site near the Los Vaqueros Reservoir. Additionally,
scenic waterways are designated by the County to ensure that preservation of the scenic character
of these waterways is considered in the project review process. The nearest County-designated
scenic waterway to the project site is the Clifton Court Forebay, approximately 1.9 miles east of
the project site.
The Byron Airport is situated in a rural area. The area has numerous wind turbines on the hill
ridges to the west, some within 1 mile of the airport. The Clifton Court Forebay is located less than
2 miles east of the site, Bethany Reservoir is approximately 3 miles to the south, and the Los
Vaqueros Reservoir is 5 miles to the west. Byron Hot Springs, a now abandoned resort and former
World War II prisoner-of-war camp, is located north of the airport. Rural residential uses surround
the airport on the east and west sides. Other significant development in the immediate vicinity
includes several high-voltage transmission lines within 3 miles to the east, west, and south of the
project site and a railroad line running parallel to the Byron Highway. The community of Byron is
located approximately 2.5 miles north of the airport. This small community is surrounded by
agricultural lands and contains concentrated areas of single-family residential development,
commercial development centralized along the Byron Highway, schools, churches, and wineries.
Nearby residences are composed of large buildings with neutral exteriors that are located on large
lots. Development is primarily located along Camino Diablo, Byron Highway, and Holway Drive.
3.1.1.2 Existing Project Site
The project site consists of the Byron Airport property south of Armstrong Road, which is
approximately 1,307 acres, and the 11.7-acre parcel located between the airport property and the
Bethany Irrigation District Canal, for a total of 1,319 acres. The airport owns an additional 120
3.1 – AESTHETICS
Byron Airport Development Program EIR 9269
February 2022 3.1-2
acres north of Armstrong Road that is not considered part of the project site. Most of the site is
open grassland, and 814 acres of the project site are reserved for habitat management and are
therefore maintained in a natural condition. The airport is located on the western edge of the flat
Sacramento-San Joaquin Delta agricultural lands and on the eastern edge of the Diablo Range. The
site’s topography consists of low rolling hills, leveling out into flat, irrigated pastures on the east
side. Two hills occupy the center of the site, extending up to 125 feet above mean sea level, 30 to
50 feet higher than most of the project site. The remainder of the site is mostly flat, and the
elevation of the property is 30 to 80 feet above mean sea level. Hills surround the project site on
all but the east and northeast sides. The hills located approximately 2.5 miles to the west of the site
range from 400 feet to above 900 feet in elevation.
The airport contains two asphalt concrete nonintersecting runways, each with a parallel taxiway and
several connector taxiways. The primary runway, Runway 12-30 (northwest–southeast), is 4,500 feet
long and 100 feet wide. The crosswind runway, Runway 5-23, is 3,000 feet long and 75 feet wide.
Both runways have 20-foot unpaved shoulders. General aviation facilities are generally concentrated
within the “V” formed by the two runways. These facilities include the administration building, the
maintenance hangar, a pump house, the 6900 Falcon Way building, and aircraft hangars.
The administration building comprises approximately 2,400 square feet. It is located at 500 Eagle
Court, adjacent to the general aviation apron. This 60-foot by 40-foot double-wide modular
building has a tan exterior and metal roof. The maintenance hangar, 505 Eagle Court, is a 75-foot
by 100-foot two-bay hangar with a simple tan exterior and metal roof.
A pump house (a 15-foot by 20-foot building) is located on the northeast side of Runway 12-30
(by Holey Road) together with a fire protection pond that serves as water supply for the airport.
There is also an emergency pump station located southeast of the runway intersection that provides
water from an underground 960-inch diameter pipe to supplement the fire protection pond. The
pump house is a gray rectangular building with a flat roof.
The 6900 Falcon Way building is located along Falcon Way towards the north side of the airport.
It is one of the original buildings from Byron Airpark, making it one of the oldest at the airport. It
is a tan building with a flat roof and an outdoor area with picnic tables. It contains a shaded open
storage area on its southern side and is presently leased to Bay Area Sky Diving.
The aircraft hangars are described by rows, starting northwest of the administration building. The
first two rows, A and B, are vacant land reserved for future development. Existing buildings start
with Row C. Row C is a 28-unit T-hangar constructed in 1996. Rows D and E are portable T-
hangars that were relocated from the original airpark in 1994. Row F has two privately owned
buildings on ground leases—a 12-unit executive hangar and a 10-unit executive hangar (which
includes an owner maintenance hangar at the eastern end). The Byron Jet Center is located north
3.1 – AESTHETICS
Byron Airport Development Program EIR 9269
February 2022 3.1-3
of the executive hangars. Hangars consist of tan rectangular buildings with metal roofs. A wash
rack is located at the east side of the Row F buildings. Wastewater from the wash rack drains
though an oil–water separator to a leach field located to the east, between the wash rack and
Taxiway A.
The majority of the project site, approximately 814 acres, is owned and managed by the County
as habitat, consistent with the East Contra Costa County Habitat Conservation Plan (HCP). The
HCP details the implementation of an avoidance and preservation program and identifies the land
that would be impacted, avoided, and preserved in perpetuity. This habitat preserve area is located
to the south and west of the airfield. Seven land cover types exist on the project site. The majority
of the site is made up of annual grassland habitat with urban areas that include the buildings, paved
areas, and ornamental landscaping associated with operation of the airport. Annual grassland
within the site is dominated by a dense to sparse cover of annual, non-native grasses and forbs.
The remaining portion of the project site consists of annual and alkali grasslands interspersed with
seasonal and alkali wetlands, as well as vernal pools. Seasonal wetlands are prevalent in the annual
grassland in the northwestern and western areas of the project site. Alkali wetlands consist of
seasonal wetlands within alkali grassland. The alkali wetlands generally consist of barren areas
where water remains inundated for prolonged periods of time during the growing season.
Several drainages also cross through the project site. These drainages appear to be intermittent in
nature, carrying water only during the wet season. The banks of the drainages are generally
dominated by non-native grasses. Brushy Creek travels through the project site from the southwest
and exits the site at the northern end of the project site. This feature holds more water than the
other drainages; however, it is still considered intermittent because it appears to dry during dry
periods. Aquatic features within the site include numerous seasonal wetlands, alkali wetlands,
swales, vernal pools, and drainages that are scattered throughout the site. Most of these features
occur in the northern and western portions of the site. Within the project site, urban areas consist
of roadways, runways, hangars, and other airport buildings. In addition, a major irrigation canal
flows northward across the eastern portion of the site, and high-pressure gas and petroleum
pipelines run diagonally through the middle of the site. Vegetation in these areas is sparse to absent,
consisting primarily of cultivated plants in planters.
3.1.1.3 Views of the Project Site from the Surrounding Area
The project site is visible from Armstrong Road to the north and west, Byron Hot Springs Road
to the east, and Holey Road to the northeast. Views of the project site can also be seen from
the Byro n Highway, approximately 0.4 miles east of the project site, and from Vasco Road to
the west. Views from the north along Armstrong Road primarily consist of short -range views
of annual grasslands, and minor long -range views of airport buildings and facilit ies. Views
along Byron Hot Springs Road to the east consist of rural residences and grasslands in the
3.1 – AESTHETICS
Byron Airport Development Program EIR 9269
February 2022 3.1-4
foreground, with minor views of airport buildings and facilities in the background. From the
west of the project site along Armstrong Road, buildings on t he project site are barely visible,
as they are blocked by small hills and grassland vegetation. Views from the west largely consist
of grassy hillsides, flat grasslands, utility poles lining Armstrong Road, and open -wire fencing.
Mature trees are scattere d across the landscape. From Vasco Road, minor views of airport
hangar buildings are available to passersby when not obscured by the rolling hills.
Key Viewpoints
Key viewpoints are shown on Figure 3.1-1. The key viewpoints were determined based on publicly
accessible areas that afford views of the project site and that may have a substantial number of
viewers. As discussed in Section 3.1.2, Relevant Plans, Policies, and Ordinances, there are no
identified scenic routes or scenic vistas with a view of the project site.
3.1.1.4 Light and Glare
Nighttime lighting is necessary to provide and maintain safe, secure, and attractive environments.
Light that falls beyond the intended area of illumination is referred to as “light trespass.” Types of
light trespass include spillover light and glare. Spillover light, which is light that illuminates
surfaces beyond the intended area, is typically caused by artificial lighting sources, such as from
building security lighting, signs, parking lot lights, roadway lights, and stadium lights on playing
fields. Spillover light can adversely affect light-sensitive uses, such as residential neighborhoods
at nighttime. Because light dissipates as it moves farther from its source, the intensity of the
lighting source is often increased to compensate for dissipating light, which can increase the
amount of light that illuminates adjacent uses. The type of light fixture determines the extent to
which light will spill over onto adjacent properties and/or be visible from far away. Modern,
energy-efficient fixtures that face downward, such as cutoff-type fixtures and shielded light
fixtures, are less obtrusive than light fixtures that have been used in the past.
The second type of light trespass is glare, which results when a light source in the field of vision
is brighter than the eye can comfortably accept. Glare can result from sunlight or from artificial
light reflecting off building exteriors, such as glass windows, metal roofs, or other highly reflective
surface materials. Squinting or turning away from a light source is an indication of glare. Cutoff-
type light fixtures minimize glare because they emit relatively low-intensity light at these angles.
Glare resulting from sunlight reflecting off building exteriors can be reduced with design features
that use low-reflective glass and exterior materials and colors that absorb, rather than reflect, light.
The project site currently supports aviation uses. Existing lighting on the airfield includes medium-
intensity runway lights, runway end identifier lights, and precision approach path indicators.
Runways 5, 12, 23, and 30 are equipped with medium-intensity runway lights and Runway 30 is
also equipped with runway end identifier lights. All runway lighting is pilot controlled by
3.1 – AESTHETICS
Byron Airport Development Program EIR 9269
February 2022 3.1-5
activating the local airport radio frequency. Runways 30 and 23 are equipped with two-light
precision approach path indicators on the left (3.5° glide path). Runways 5 and 12 currently do not
have approach lighting systems. The airport apron, parking, and hangar area is illuminated with
ramp floodlights that are photocell controlled. Existing buildings, parking areas, passenger
boarding areas, and maintenance areas on the project site are illuminated with safety and security
lighting. As the project site is located in a rural area, surrounding lighting is minimal.
3.1.2 Relevant Plans, Policies, and Ordinances
Federal
There are no federal regulations pertaining to visual resources that would apply to the proposed project.
State
California Scenic Highway Program
California’s Scenic Highway Program was created by the legislature in 1963 to preserve and protect
scenic highway corridors from change that would diminish the aesthetic value of lands adjacent to
highways. The state laws governing the Scenic Highway Program are found in the Streets and
Highways Code, Section 260 et seq. The Scenic Highway System includes a list of highways that are
either eligible for designation as scenic highways or have been so designated. County roads can also
become part of the Scenic Highway System. To receive official designation, the County must follow
the same process required for official designation of State Scenic Highways.
The nearest designated state scenic highway is State Route (SR) 680 from the Alameda County
boundary to SR-24, approximately 19.8 miles west of the project site. The nearest portion of an
eligible scenic highway is the segment of SR-4 from SR-160 near Antioch to SR-84 near
Brentwood, which is located approximately 6.4 miles northwest of the project site (Caltrans 2017).
Local
Contra Costa County General Plan
The Open Space Element of the County General Plan provides objectives, policies, and programs
regarding aesthetics, including the following (Contra Costa County 2005b):
Goal 9-A To preserve and protect the ecological, scenic, cultural/historic, and recreational
resource lands of the county.
3.1 – AESTHETICS
Byron Airport Development Program EIR 9269
February 2022 3.1-6
Goal 9-2 Historic and scenic features, watersheds, natural waterways, and areas important
for the maintenance of natural vegetation and wildlife populations shall be
preserved and enhanced.
Goal 9-D To preserve and protect areas of identified high scenic value, where practical, and
in accordance with the Land Use Element Map.
Goal 9-F To preserve the scenic qualities of the San Francisco Bay/Delta estuary system and
the Sacramento-San Joaquin River/Delta shoreline.
Policy 9-10 In areas designated for urban development, the principles outlined
below shall be applied in the review of development proposals.
Policy 9-11 High-quality engineering of slopes shall be required to avoid soil
erosion, downstream flooding, slope failure, loss of vegetative
cover, high maintenance costs, property damage, and damage to
visual quality. Particularly vulnerable areas should be avoided for
urban development. Slopes of 26% or more should generally be
protected and are generally not desirable for conventional cut-and-
fill pad development. Development on open hillsides and significant
ridgelines shall be restricted.
Policy 9-12 In order to conserve the scenic beauty of the county, developers shall
generally be required to restore the natural contours and vegetation
of the land after grading and other land disturbances. Public and
private projects shall be designed to minimize damage to significant
trees and other visual landmarks.
Policy 9-14 Extreme topographic modification, such as filling in canyons or
removing hilltops, shall be avoided. Clustering and planned unit
development approaches to development shall be encouraged. All
future development plans, whether large- or small-scale, shall be
based on identifying safe and suitable sites for buildings, roads, and
driveways. Exemptions to this policy are appropriate for mining,
landfill, and public projects in open space areas.
Policy 9-24 The appearance of the county shall be improved by eliminating
negative features such as non-conforming signs and overhead utility
lines, and by encouraging aesthetically designed facilities with
adequate setbacks and landscaping.
3.1 – AESTHETICS
Byron Airport Development Program EIR 9269
February 2022 3.1-7
Policy 9-25 Maintenance of the scenic waterways of the county shall be ensured
through public protection of the marshes and riparian vegetation along
the shorelines and delta levees, as otherwise specified in this Plan.
Policy 9-27 Physical and visual public access to established scenic routes shall
be protected.
Contra Costa County Zoning
The airport’s current zoning is P-1, for planned development. This zoning is intended to foster a
diversification of land uses, buildings, structures, lot sizes, and open space while complying with
the General Plan and County code standards (Contra Costa County Zoning Ordinance, Division
84, Chapter 66). Within the overall airport zone are four separate zones, aviation, airport related,
low intensity use, and habitat management. Parcels surrounding the project site are primarily zoned
for agricultural uses, including General Agriculture (A-2), Heavy Agriculture (A-3), and
Agricultural Preserve (A-4) (Contra Costa County 2015). The County General Plan designates the
project site’s land use as Public/Semi-Public (PS), with the area immediately surrounding the
project site being designated Open Space (OS) on the west and Agricultural Lands (AL) on the
east (Contra Costa County 2014).
While the zoning ordinance does not specifically regulate visual quality, it provides a basis for lot
coverage, setbacks, and building mass that affects the visual qualities of development.
3.1.3 Thresholds of Significance
The significance criteria used to evaluate the project impacts to aesthetics are based on Appendix
G of the CEQA Guidelines. According to Appendix G of the CEQA Guidelines, a significant
impact related to aesthetics would occur if the project would:
1. Have a substantial adverse effect on a scenic vista.
2. Substantially damage scenic resources, including, but not limited to trees, rock
outcroppings, and historic buildings within a state scenic highway.
3. 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?
4. Create a new source of substantial light or glare which would adversely affect day or
nighttime views in the area.
The project site is not visible from a state scenic highway and this impact is not considered further.
3.1 – AESTHETICS
Byron Airport Development Program EIR 9269
February 2022 3.1-8
The project is located in a largely rural, agricultural area. Therefore, the approach to changes in
visual character and quality is based generally on a simplified version of the Federal Highway
Administration’s methodology for visual impact assessment (FHWA 2015). This methodology
focuses on the character and quality of existing resources, the degree of potential change, and the
sensitivity and exposure of view groups. Visual simulations are used to demonstrate the degree of
change in the existing environment from the key viewpoints.
Light and glare impacts are considered in the context of existing regulations regarding lighting,
and, similar to visual character, the degree of change experienced by the public.
3.1.4 Impacts Analysis
Impact 3.1-1. The project would not have a substantial adverse effect on a scenic vista.
(Less than Significant)
The project site includes areas planned for aviation, non-aviation , low-intensity, and habitat
management uses. The 23.5-acre area identified for aviation uses is generally located west of
the intersection of the two runways . The 46.6-acre area designated for non-aviation is generally
located east of the runways . These two areas could be developed with aviation and aviation -
compatible uses , respectively . The low-intensity area, approximately 31 acres, is reserved by
the County for infrastructure and/or protection of the airfield. The habitat management lands
are not subject to development.
Proposed land uses in the aviation area include airport infrastructure (e.g., control tower,
terminals), hangars, fixed-base operators, businesses that directly support aviation and travel (e.g.,
aircraft service and fuel, rental car facilities, pilots lounge, meeting facilities), and businesses that
directly rely on aviation (e.g., agricultural aviation, aerial surveys and photography, air charter
businesses, air cargo, just-in-time delivery). These uses would operate within buildings and
structures that would be visually consistent with the existing buildings and structures on the project
site and would support or be attached to the existing aviation uses on the site. Buildings would
generally be low to the ground (typically 30 to 40 feet in height) and not very visible except from
the immediate vicinity. Proposed land uses in the non-aviation area would include industrial,
commercial, and office uses. These land uses would be subject to County zoning controls for height
and bulk.
As described above, the nearest County-designated scenic ridgeway is approximately 7.2 miles
west of the project site and the nearest County-designated scenic waterway to the project site is
located approximately 1.9 miles east of the project site. Due to distance and topography, the project
site is not visible from these areas, and would not obstruct public views of these visual resources.
The majority of the project site would continue to be preserved as a habitat management area or
low-intensity use. Therefore, this area would remain as open grassland. New buildings and
3.1 – AESTHETICS
Byron Airport Development Program EIR 9269
February 2022 3.1-9
structures would only be placed within the 70 acres designated for aviation and non-aviation uses
near the existing airport development. The aviation uses and airport compatible uses that would be
developed within this area would be consistent with the existing aviation facilities on the project
site, including administration buildings, aircraft hangars, and aviation support buildings.
Because the proposed project would not obstruct or interfere with views from or to a designated
scenic vista, this impact would be less than significant.
Impact 3.1-2. The project would not substantially degrade the existing visual character or
quality of public views of the site and its surroundings. (Potentially Significant)
The project site predominantly consists of annual grassland habitat with urban areas that include
the buildings, paved areas and ornamental landscaping associated with operation of the airport.
The Byron Airport Master Plan designates areas within the airport property for aviation, airport-
related, low-intensity, and habitat management uses. The project would add 11.7 acres to the
airport site and allow development in two areas on the airport: a 23.5-acre area identified for
aviation uses, generally located west of the primary runway, and 46.6 acres designated for non-
aviation uses, generally located east of the primary runway. The remaining areas would not be
developed in the foreseeable future, including the habitat management lands.
Proposed land uses in the aviation area include airport infrastructure (e.g., control tower,
terminals), hangars, fixed-base operators, businesses that directly support aviation and travel, (e.g.,
aircraft service and fuel, rental car facilities, pilots lounge, meeting facilities), and businesses that
rely on aviation (e.g., agricultural aviation, aerial surveys and photography, air charter businesses,
air cargo, just-in-time delivery). These uses would operate within buildings and structures that
would be visually consistent with the existing buildings and structures on the project site and would
support or be attached to the existing aviation uses on the site.
Development of non-aviation uses would predominantly occur along the eastern border of the site.
These uses may include warehousing, light industrial, office, and commercial uses. The buildings
would be generally consistent with the existing visual character of the site—large single-story
buildings—and would not significantly change the visual character of the area.
Visual simulations of potential building massing for the airport-related land uses are shown in
Figure 3.1-2a, Figure 3.1-2b, and Figure 3.1-2c. The building mass is based on a 35-acre
warehousing and logistics project (a development that is considered within the scope of this
Environmental Impact Report). The potential building mass is shown from the three key
viewpoints shown in Figure 3.1-1. Airport development would not substantially change the visual
character and quality of the project site from key viewpoints 2 and 3. Viewpoint 1, at Armstrong
Road and Byron Hot Springs Road, could be affected by the construction of large warehouses in
the northeast area of the project site. The modeled height of the warehouses is 35 to 40 feet.
3.1 – AESTHETICS
Byron Airport Development Program EIR 9269
February 2022 3.1-10
Depending on the massing of these buildings, the impact to public views (public road adjacent to
the airport) would be potentially significant.
Impact 3.1-3. The project would not create a new source of substantial light or glare which
would adversely affect day or nighttime views in the area. (Less than Significant)
Existing lighting sources on the project site include medium-intensity runway lights, runway end
identifier lights, and precision approach path indicators as navigation aids on the airfield, along
with lighting associated with existing buildings, parking areas, passenger boarding areas, and
aircraft maintenance areas on site. The airport apron, parking, and hangar area is illuminated with
ramp floodlights that are photocell controlled. The project site is located in a rural area with
minimal lighting sources. Introduction of proposed land uses, including airport infrastructure,
hangars, fixed-based operators, and businesses that support aviation and travel or that rely on
aviation would increase lighting at the project site. Proposed industrial and commercial uses would
include additional lighting sources, including parking lot and building lighting.
The Federal Aviation Administration has established requirements for aeronautical ground lighting
systems such as runway, taxiway, and approach lighting. Light spillage and glare from non-
aviation land uses are hazards to pilots and tower personnel. Glare can impact the visibility of
important aircraft navigation aids such as ground lighting, directional signs, and painted markings
on the airfield. Furthermore, tower personnel can be impacted by directed glare, backscatter, and
reflections that make it difficult to observe the area beyond the apron into the active airfield area.
Light and glare impacts are addressed in the land use consistency policies of the Airport Land Use
Compatibility Plan. All proposed on-airport land uses are subject to review by County staff for
consistency with the Airport Land Use Compatibility Plan and Federal Aviation Administration
criteria. Compliance with existing Airport Land Use Compatibility Plan policies would ensure that
potential impacts would be less than significant.
3.1.5 Mitigation Measures
To reduce the effects of changes to public views, the following mitigation measure (MM) should
be implemented.
MM-AES-1 Non-aviation development shall be subject to the following design requirements:
• Long facades should be designed with building articulation and landscaping to
break them up into smaller visual elements, avoiding public views of
uninterrupted blank walls.
3.1 – AESTHETICS
Byron Airport Development Program EIR 9269
February 2022 3.1-11
• For industrial and warehouse buildings, bright reflective colors and materials
shall not be allowed. Paint colors should be earth tones. Natural finishes such
as brick or stone facades may also be incorporated into the design.
• Project lighting shall comply with the policies of the Airport Land Use
Compatibility Plan.
• Loading areas should be located and designed to minimize direct exposure to
public views.
• Structures and parking lots located on the eastern edge of the airport property
shall incorporate landscaping to screen public views. The type, quantity and
placement of plant material should be selected for its compatibility with airport
uses (tree heights, plants that are not wildlife attractants), as well as structure,
texture, color and compatibility with the building design and materials.
The design of non-aviation development shall be reviewed by both the Department of
Conservation and Development and Airports Division staff prior to issuance of building permits
for conformance with these standards. Aviation uses shall be reviewed by Byron Airports Division
staff.
3.1.6 Level of Significance After Mitigation
Implementation of MM-AES-1 would reduce Impact 3.1-2 to a less-than-significant level.
3.1.7 Cumulative Impacts
The cumulative context for the project consists of the surrounding areas visible from the key
viewpoints. These areas include agricultural lands, wind energy development, and scattered rural
and light industrial development. No other development is proposed within the key viewpoints.
Although single-family homes and agricultural structures are allowed by right in the agricultural
zones near the airport, this area has relatively little growth and these structures would be consistent
with the existing visual character.

3.2 AIR QUALITY
This section describes the impacts on air quality and contribution to regional air quality conditions,
identifies associated regulatory requirements, evaluates potential impacts, and identifies mitigation
measures related to implementation of the proposed Byron Airport Development Program (project).
3.2.1 Existing Conditions
The project site is located in Contra Costa County (County), within the boundaries of the San
Francisco Bay Area Air Basin (SFBAAB). The SFBAAB encompasses all of Alameda, Contra
Costa, Marin, Napa, San Francisco, San Mateo, and Santa Clara Counties and the southern portions
of Solano and Sonoma Counties.
Air pollutants are emitted by a variety of sources, including mobile sources (vehicles), area sources
(hearths, consumer product use, architectural coatings, and landscape maintenance equipment),
energy sources (natural gas), and stationary sources (generators or other stationary equipment).
Some air pollutants need to be examined at the local level, and others are predominantly an issue
at the regional level. For instance, ozone (O3) is formed in the atmosphere in the presence of
sunlight by a series of chemical reactions involving oxides of nitrogen (NOx) and reactive organic
gas (ROG) (also termed volatile organic compounds). Because these reactions have broad-scale
effects, O3 is typically analyzed at the regional level (i.e., in the air basin) rather than the local
level. On the other hand, air pollutants such as coarse particulate matter (PM10), fine particulate
matter (PM2.5), carbon monoxide (CO), and toxic air contaminants (TACs) are a potential concern
in the immediate vicinity of the pollutant source because the pollutants are emitted directly by or
are formed close to the source. Therefore, the study area for emissions of PM10, PM2.5, CO, and
TACs is the local area near the source, such as in the vicinity of the project site, and the study area
for regional pollutants such as NOx and ROGs is the entire SFBAAB.
3.2.1.1 Regional Climatology
Air quality is a function of the rate and location of pollutant emissions under the influence of
meteorological conditions and topographic features that influence pollutant movement and
dispersal. Atmospheric conditions such as wind speed, wind direction, atmospheric stability, and
air temperature gradients interact with the physical features of the landscape to determine the
movement and dispersal of air pollutants, and consequently affect air quality.
The climate of the SFBAAB is determined largely by a high-pressure system that is almost always
present over the eastern Pacific Ocean off the west coast of North America. During winter, the
Pacific high-pressure system shifts southward, allowing more storms to pass through the region.
During summer and early fall, when few storms pass through the region, emissions generated
within the Bay Area can combine with abundant sunshine under the restraining influences of
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-2
topography and subsidence inversions to create conditions that are conducive to the formation of
photochemical pollutants, such as O3, and secondary particulates, such as nitrates and sulfates.
In the SFBAAB, temperature inversions can often occur during the summer and winter months.
An inversion is a layer of warmer air over a layer of cooler air that traps and concentrates pollutants
near the ground. As such, the highest air pollutant concentrations in the SFBAAB generally occur
during inversions (BAAQMD 2017a).
The project site is located in the southeastern border of the County, at the edge of the Livermore
Valley climatological subregion. Specific conditions for the subregion are described in the Bay
Area Air Quality Management District (BAAQMD) California Environmental Quality Act Air
Quality Guidelines (BAAQMD 2017a). Maximum summer temperatures in the Livermore Valley
range from the high-80s°F to the low-90s°F, with extremes in the 100s°F. Average winter
maximum temperatures range from the high-50s°F to the low-60s°F, while minimum temperatures
are from the mid-to-high-30s°F, with extremes in the high-10s°F and low-20s°F (BAAQMD
2017a). On the eastern side of the valley, such as where the project is located, the prevailing winds
blow from north, northeast, and east. At times during the summer, a strong Pacific high-pressure
cell from the west, coupled with hot inland temperatures, causes a strong onshore pressure gradient
which produces a strong, afternoon wind (BAAQMD 2017a). During the winter, winds are
typically light during the late night and early morning hours, and daytime winds sometimes flow
from the south through the Altamont Pass to the San Joaquin Valley (BAAQMD 2017a).
3.2.1.2 Pollutants and Effects
Criteria Air Pollutants
Criteria air pollutants are defined as pollutants for which the federal and state governments have
established ambient air quality standards, or criteria, for outdoor concentrations to protect public health.
The federal and state standards have been set, with an adequate margin of safety, at levels above which
concentrations could be harmful to human health and welfare. These standards are designed to protect
the most sensitive persons from illness or discomfort. Pollutants of concern include O3, nitrogen
dioxide (NO2), CO, sulfur dioxide (SO2), PM10, PM2.5, and lead. These pollutants, as well as TACs,
are discussed in the following paragraphs.1 In California, sulfates, vinyl chloride, hydrogen sulfide,
and visibility-reducing particles are also regulated as criteria air pollutants.
1 The descriptions of the criteria air pollutants and associated health effects are based on the U.S. Environmental
Protection Agency’s Criteria Air Pollutants (EPA 2018a) and the California Air Resources Board’s Glossary
(CARB n.d.) and Fact Sheet: Air Pollution Sources, Effects and Control (CARB 2009).
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-3
Ozone
O3 is a strong-smelling, pale blue, reactive, toxic chemical gas consisting of three oxygen atoms.
It is a secondary pollutant formed in the atmosphere by a photochemical process involving the
sun’s energy and O3 precursors. These precursors are mainly NOx and ROGs. The maximum
effects of precursor emissions on O3 concentrations usually occur several hours after they are
emitted and many miles from the source. Meteorology and terrain play major roles in O3 formation,
and ideal conditions occur during summer and early autumn on days with low wind speeds or
stagnant air, warm temperatures, and cloudless skies. O3 exists in the upper atmosphere O3 layer
(stratospheric ozone) and at the Earth’s surface in the troposphere (tropospheric ozone).2 The O3
that the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board
(CARB) regulate as a criteria air pollutant is produced close to ground level, where people live,
exercise, and breathe. Ground-level O3 is a harmful air pollutant that causes numerous adverse
health effects and is thus considered bad O3. Stratospheric, or good, O3 occurs naturally in the
upper atmosphere, where it reduces the amount of ultraviolet light (i.e., solar radiation) entering
the Earth’s atmosphere. Without the protection of the beneficial stratospheric O3 layer, plant and
animal life would be seriously harmed.
O3 in the troposphere causes numerous adverse health effects; short-term exposures (lasting for a
few hours) to O3 can result in breathing pattern changes, reduction of breathing capacity, increased
susceptibility to infections, inflammation of the lung tissue, and some immunological changes
(EPA 2013). These health problems are particularly acute in sensitive receptors such as the sick,
the elderly, and young children.
Nitrogen Dioxide
NO2 is a brownish, highly reactive gas that is present in all urban atmospheres. The major
mechanism for the formation of NO2 in the atmosphere is the oxidation of the primary air pollutant
nitric oxide, which is a colorless, odorless gas. NOx plays a major role, together with ROGs, in the
atmospheric reactions that produce O3. NOx is formed from fuel combustion under high
temperature or pressure. In addition, NOx is an important precursor to acid rain and may affect
both terrestrial and aquatic ecosystems. The two major emissions sources are transportation and
stationary fuel combustion sources such as electric utility and industrial boilers.
NO2 can irritate the lungs, cause bronchitis and pneumonia, and lower resistance to respiratory
infections (EPA 2016).
2 The troposphere is the layer of the Earth’s atmosphere nearest to the surface of the Earth. The troposphere extends
outward about 5 miles at the poles and about 10 miles at the equator.
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-4
Carbon Monoxide
CO is a colorless, odorless gas formed by the incomplete combustion of hydrocarbon, or fossil
fuels. CO is emitted almost exclusively from motor vehicles, power plants, refineries, industrial
boilers, ships, aircraft, and trains. In urban areas, automobile exhaust accounts for the majority of
CO emissions. CO is a nonreactive air pollutant that dissipates relatively quickly; therefore,
ambient CO concentrations generally follow the spatial and temporal distributions of vehicular
traffic. CO concentrations are influenced by local meteorological conditions—primarily wind
speed, topography, and atmospheric stability. CO from motor vehicle exhaust can become locally
concentrated when surface-based temperature inversions are combined with calm atmospheric
conditions, which is a typical situation at dusk in urban areas from November to February. The
highest levels of CO typically occur during the colder months of the year, when inversion
conditions are more frequent.
In terms of adverse health effects, CO competes with oxygen, often replacing it in the blood,
reducing the blood’s ability to transport oxygen to vital organs. The results of excess CO exposure
can include dizziness, fatigue, and impairment of central nervous system functions.
Sulfur Dioxide
SO2 is a colorless, pungent gas formed primarily from incomplete combustion of sulfur-containing
fossil fuels. The main sources of SO2 are coal and oil used in power plants and industries; as such,
the highest levels of SO2 are generally found near large industrial complexes. In recent years, SO2
concentrations have been reduced by the increasingly stringent controls placed on stationary
source emissions of SO2 and limits on the sulfur content of fuels.
SO2 is an irritant gas that attacks the throat and lungs and can cause acute respiratory symptoms
and diminished ventilator function in children. When combined with particulate matter, SO2 can
injure lung tissue and reduce visibility and the level of sunlight. SO2 can also yellow plant leaves
and erode iron and steel.
Particulate Matter
Particulate matter pollution consists of very small liquid and solid particles floating in the air,
which can include smoke, soot, dust, salts, acids, and metals. Particulate matter can form when
gases emitted from industries and motor vehicles undergo chemical reactions in the atmosphere.
PM2.5 and PM10 represent fractions of particulate matter. Coarse particulate matter (PM10) consists
of particulate matter that is 10 microns or less in diameter and is about 1/7 the thickness of a human
hair. Major sources of PM10 include crushing or grinding operations; dust stirred up by vehicles
traveling on roads; wood-burning stoves and fireplaces; dust from construction, landfills, and
agriculture; wildfires and brush/waste burning; industrial sources; windblown dust from open
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-5
lands; and atmospheric chemical and photochemical reactions. Fine particulate matter (PM2.5)
consists of particulate matter that is 2.5 microns or less in diameter and is roughly 1/28 the diameter
of a human hair. PM2.5 results from fuel combustion (e.g., from motor vehicles and power
generation and industrial facilities), residential fireplaces, and woodstoves. In addition, PM2.5 can
be formed in the atmosphere from gases such as sulfur oxides, NOx, and ROGs.
PM2.5 and PM10 pose a greater health risk than larger-size particles. When inhaled, these tiny particles
can penetrate the human respiratory system’s natural defenses and damage the respiratory tract. PM2.5
and PM10 can increase the number and severity of asthma attacks, cause or aggravate bronchitis and
other lung diseases, and reduce the body’s ability to fight infections. Very small particles of substances
such as lead, sulfates, and nitrates can cause lung damage directly or be absorbed into the bloodstream,
causing damage elsewhere in the body. Additionally, these substances can transport adsorbed gases
such as chlorides or ammonium into the lungs, also causing injury. Whereas PM10 tends to collect in
the upper portion of the respiratory system, PM2.5 is so tiny that it can penetrate deeper into the lungs
and damage lung tissue. Suspended particulates also damage and discolor surfaces on which they settle
and produce haze and reduce regional visibility.
People with influenza, people with chronic respiratory and cardiovascular diseases, and the elderly
may suffer worsening illness and premature death as a result of breathing particulate matter. People
with bronchitis can expect aggravated symptoms from breathing in particulate matter. Children
may experience a decline in lung function due to breathing in PM10 and PM2.5 (EPA 2009).
Lead
Lead in the atmosphere occurs as particulate matter. Sources of lead include leaded gasoline; the
manufacturing of batteries, paints, ink, ceramics, and ammunition; and secondary lead s melters.
Prior to 1978, mobile emissions were the primary source of atmospheric lead. Between 1978 and
1987, the phaseout of leaded gasoline reduced the overall inventory of airborne lead by nearly
95%. With the phaseout of leaded gasoline, secondary lead smelters, battery recycling, and
manufacturing facilities are becoming lead-emissions sources of greater concern.
Prolonged exposure to atmospheric lead poses a serious threat to human health. Health effects
associated with exposure to lead include gastrointestinal disturbances, anemia, kidney disease, and
in severe cases, neuromuscular and neurological dysfunction. Of particular concern are low -level
lead exposures during infancy and childhood. Such exposures are associated with decrements in
neurobehavioral performance, including intelligence quotient performance, psychomotor
performance, reaction time, and growth. Children are highly susceptible to the effects of lead.
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-6
Sulfates
Sulfates are the fully oxidized form of sulfur, which typically occur in combination with metals or
hydrogen ions. Sulfates are produced from reactions of SO2 in the atmosphere and can result in
respiratory impairment, as well as reduced visibility.
Vinyl Chloride
Vinyl chloride is a colorless gas with a mild, sweet odor, which has been detected near landfills,
sewage plants, and hazardous waste sites, due to the microbial breakdown of chlorinated solvents.
Short-term exposure to high levels of vinyl chloride in air can cause nervous system effects, such
as dizziness, drowsiness, and headaches. Long-term exposure through inhalation can cause liver
damage, including liver cancer.
Hydrogen Sulfide
Hydrogen sulfide is a colorless and flammable gas that has a characteristic odor of rotten eggs.
Sources of hydrogen sulfide include geothermal power plants, petroleum refineries, sewers, and
sewage treatment plants. Exposure to hydrogen sulfide can result in nuisance odors, as well as
headaches and breathing difficulties at higher concentrations.
Visibility-Reducing Particles
Visibility-reducing particles are any particles in the air that obstruct the range of visibility. Effects
of reduced visibility can include obscuring the viewshed of natural scenery, reducing airport safety,
and discouraging tourism. Sources of visibility-reducing particles are the same as for PM2.5
described above.
Reactive Organic Gases
Hydrocarbons are organic gases that are formed from hydrogen and carbon and sometimes other
elements. Hydrocarbons that contribute to formation of O3 are referred to and regulated as ROGs
(also referred to as volatile organic compounds). Combustion engine exhaust, oil refineries, and
fossil-fueled power plants are the sources of hydrocarbons. Other sources of hydrocarbons include
evaporation from petroleum fuels, solvents, dry cleaning solutions, and paint.
The primary health effects of ROGs result from the formation of O3 and its related health effects.
High levels of ROGs in the atmosphere can interfere with oxygen intake by reducing the amount
of available oxygen through displacement. Carcinogenic forms of hydrocarbons, such as benzene,
are considered TACs. There are no separate health standards for ROGs as a group.

Non-Criteria Air Pollutants
Toxic Air Contaminants
A substance is considered toxic if it has the potential to cause adverse health effects in humans,
including increasing the risk of cancer upon exposure, or acute and/or chronic noncancer health
effects. A toxic substance released into the air is considered a TAC. TACs are identified by federal
and state agencies based on a review of available scientific evidence. In the State of California,
TACs are identified through a two-step process that was established in 1983 under the Toxic Air
Contaminant Identification and Control Act. This two-step process of risk identification and risk
management and reduction was designed to protect residents from the health effects of toxic
substances in the air. In addition, the California Air Toxics “Hot Spots” Information and
Assessment Act, Assembly Bill (AB) 2588, was enacted by the legislature in 1987 to address
public concern over the release of TACs into the atmosphere. The law requires facilities emitting
toxic substances to provide local air pollution control districts with information that will allow an
assessment of the air toxics problem, identification of air toxics emissions sources, location of
resulting hotspots, notification of the public exposed to significant risk, and development of
effective strategies to reduce potential risks to the public over 5 years.
Examples include certain aromatic and chlorinated hydrocarbons, certain metals, and asbestos.
TACs are generated by a number of sources, including stationary sources, such as dry cleaners,
gas stations, combustion sources, and laboratories; mobile sources, such as automobiles; and area
sources, such as landfills. Adverse health effects associated with exposure to TACs may include
carcinogenic (i.e., cancer-causing) and noncarcinogenic effects. Noncarcinogenic effects typically
affect one or more target organ systems and may be experienced on either short -term (acute) or
long-term (chronic) exposure to a given TAC.
Diesel Particulate Matter
Diesel particulate matter (DPM) is part of a complex mixture that makes up diesel exhaust. Diesel
exhaust is composed of two phases, gas and particle, both of which contribute to health risks. More
than 90% of DPM is less than 1 micrometer in diameter (about 1/70th the diameter of a human
hair), and thus is a subset of PM2.5 (CARB n.d.). DPM is typically composed of carbon particles
(soot, also called black carbon) and numerous organic compounds, including over 40 known
cancer-causing organic substances. Examples of these chemicals include polycyclic aromatic
hydrocarbons, benzene, formaldehyde, acetaldehyde, acrolein, and 1,3-butadiene (CARB n.d.).
CARB classified “particulate emissions from diesel-fueled engines” (i.e., DPM) (17 CCR 93000)
as a TAC in August 1998. DPM is emitted from a broad range of diesel engines: on -road diesel
engines of trucks, buses, and cars and off-road diesel engines including locomotives, marine
vessels, and heavy-duty construction equipment, among others.
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-8
Approximately 70% of all airborne cancer risk in California is associated with DPM (CARB 2000).
To reduce the cancer risk associated with DPM, CARB adopted a diesel risk reduction plan in
2000 (CARB 2000). Because it is part of PM2.5, DPM also contributes to the same non-cancer
health effects as PM2.5 exposure. These effects include premature death; hospitalizations and
emergency department visits for exacerbated chronic heart and lung disease, including asthma;
increased respiratory symptoms; and decreased lung function in children. Several studies suggest
that exposure to DPM may also facilitate development of new allergies (CARB n.d.). Those most
vulnerable to non-cancer health effects are children, whose lungs are still developing, and the
elderly, who often have chronic health problems.
Odorous Compounds
Odors are generally regarded as an annoyance rather than a health hazard. Manifestations of a
person’s reaction to odors can range from psychological (e.g., irritation, anger, or anxiety) to
physiological (e.g., circulatory and respiratory effects, nausea, vomiting, and headache). The
ability to detect odors varies considerably among the population and overall is quite subjective.
People may have different reactions to the same odor. An odor that is offensive to one person may
be perfectly acceptable to another (e.g., coffee roaster). An unfamiliar odor is more easily detected
and is more likely to cause complaints than a familiar one. In a phenomenon known as odor fatigue,
a person can become desensitized to almost any odor, and recognition may only occur with an
alteration in the intensity. The occurrence and severity of odor impacts depend on the nature,
frequency, and intensity of the source; wind speed and direction; and the sensitivity of receptors.
3.2.1.3 Regional and Local Air Quality
CARB, air districts, and other agencies monitor ambient air quality at approximately 250 air
quality monitoring stations across the state. Air quality monitoring stations usually measure
pollutant concentrations 10 feet above ground level; therefore, air quality is often referred to in
terms of ground-level concentrations. The most recent background ambient air quality data from
2015 to 2017 are presented in Table 3.2-1. The Livermore–Patterson Pass monitoring station,
located at 13224 Patterson Pass Road, Livermore, California 94550, is the nearest air quality
monitoring station to the project site, located approximately 10 miles south of the project site. Air
quality data for O3 and NO2 from this monitoring station are provided in Table 3.2-1. Because the
Livermore–Patterson Pass monitoring station does not measure all pollutants, CO, PM10, and SO2
measurements were taken from the Bethel Island monitoring station (5551 Bethel Island Road,
Bethel Island, California 94511, approximately 12 miles north of the project site), and PM2.5
measurements were taken from the Livermore–Rincon Avenue monitoring station (793 Rincon
Avenue, Livermore, California 94550, approximately 13 miles southwest of the project site). The
data collected at these stations are considered generally representative of the air quality
experienced in the project vicinity. The number of days exceeding the ambient air quality standards
is also shown in Table 3.2-1.

Exceedances of federal and state standards are only shown for O3 and particulate matter. Daily exceedances for particulate matter are estimated
days because PM10 and PM2.5 are not monitored daily. All other criteria pollutants did not exceed federal or state standards during the years
shown. There is no federal standard for 1-hour ozone, annual PM10, or 24-hour SO2, nor is there a state 24-hour standard for PM2.5.
Livermore Monitoring Stations are located at 13224 Patterson Pass Road and 793 Rincon Avenue, Livermore, California 94550.
Bethel Island Monitoring Station is located at 5551 Bethel Island Road, Bethel Island, California 94511.
a Measurements of PM10 and PM2.5 are usually collected every 6 days and every 1 to 3 days, respectively. Number of days exceeding the
standards is a mathematical estimate of the number of days concentrations would have been greater than the level of the stand ard had
each day been monitored. The numbers in parentheses are the measured number of samples that exceeded the standard.
3.2.1.4 Sensitive Receptors
Some land uses are considered more sensitive to changes in air quality than others, depending on
the population groups and the activities involved. People most likely to be affected by air pollution
include children, the elderly, athletes, and people with cardiovascular and chronic respiratory
diseases. Facilities and structures where these air pollution–sensitive people live or spend
considerable amounts of time are known as sensitive receptors. Land uses where air pollution–
sensitive individuals are most likely to spend time include schools and schoolyards, parks and
playgrounds, daycare centers, nursing homes, hospitals, and residential communities (sensitive
sites or sensitive land uses) (CARB 2005). Proximate sensitive receptors to the project site include
several residences along Byron Hot Springs Road, the nearest of which is located approximately
300 feet to the east of the project site.
3.2.2 Relevant Plans, Policies, and Ordinances
Federal
Criteria Air Pollutants
The federal Clean Air Act, passed in 1970 and last amended in 1990, forms the basis for the
national air pollution control effort. The EPA is responsible for implementing most aspects of the
Clean Air Act, including setting National Ambient Air Quality Standards (NAAQS) for major air
pollutants; setting hazardous air pollutant (HAP) standards; approving state attainment plans;
setting motor vehicle emission standards; issuing stationary source emission standards and
permits; and establishing acid rain control measures, stratospheric O3 protection measures, and
enforcement provisions. Under the Clean Air Act, NAAQS are established for the following
criteria pollutants: O3, CO, NO2, SO2, PM10, PM2.5, and lead.
The NAAQS describe acceptable air quality conditions designed to protect the health and welfare
of the citizens of the nation. The NAAQS (other than for O3, NO2, SO2, PM10, PM2.5, and those
based on annual averages or arithmetic mean) are not to be exceeded more than once per year.
NAAQS for O3, NO2, SO2, PM10, and PM2.5 are based on statistical calculations over 1- to 3-year
periods, depending on the pollutant. The Clean Air Act requires the EPA to reassess the NAAQS
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-11
at least every 5 years to determine whether adopted standards are adequate to protect public health
based on current scientific evidence. States with areas that exceed the NAAQS must prepare state
implementation plans that demonstrate how those areas will attain the standards within mandated
time frames.
Pursuant to the 1990 federal Clean Air Act amendments, the EPA classifies air basins (or portions
thereof) as “attainment” or “nonattainment” for each criteria air pollutant, based on whether the
NAAQS have been achieved. Generally, if the recorded concentrations of a pollutant are lower
than the standard, the area is classified as attainment for that pollutant. If an area exceeds the
standard, the area is classified as nonattainment for that pollutant. If there is not enough data
available to determine whether the standard is exceeded in an area, the area is designated as
“unclassified” or “unclassifiable.” The designation of “unclassifiable/attainment” means that the
area meets the standard or is expected to meet the standard despite a lack of monitoring data. Areas
that achieve the standards after a nonattainment designation are redesignated as maintenance areas
and must have approved maintenance plans to ensure continued attainment of the standards.
Hazardous Air Pollutants
The 1977 federal Clean Air Act amendments required the EPA to identify national emission
standards for HAPs to protect public health and welfare. HAPs include certain volatile organic
chemicals, pesticides, herbicides, and radionuclides that present a tangible hazard, based on
scientific studies of exposure to humans and other mammals. Under the 1990 federal Clean Air
Act amendments, which expanded the control program for HAPs, 189 substances and chemical
families were identified as HAPs.
State
Criteria Air Pollutants
The federal Clean Air Act delegates the regulation of air pollution control and the enforcement of
the NAAQS to the states. In California, the task of air quality management and regulation has been
legislatively granted to CARB, with subsidiary responsibilities assigned to air quality management
districts and air pollution control districts at the regional and county levels. CARB, which became
part of the California Environmental Protection Agency in 1991, is responsible for ensuring
implementation of the California Clean Air Act of 1988, responding to the federal Clean Air Act,
and regulating emissions from motor vehicles and consumer products.
CARB has established California Ambient Air Quality Standards (CAAQS), which are generally
more restrictive than the NAAQS. The CAAQS describe adverse conditions; that is, pollution
levels must be below these standards before a basin can attain the standard. Air quality is
considered in attainment if pollutant levels are continuously below the CAAQS and violate the
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-12
standards no more than once each year. The CAAQS for O3, CO, SO2 (1-hour and 24-hour), NO2,
PM10, and PM2.5 and visibility-reducing particles are values that are not to be exceeded. All others
are not to be equaled or exceeded.
The California Clean Air Act, like its federal counterpart, called for the designation of areas as
attainment or nonattainment, but based on CAAQS rather than the NAAQS. The NAAQS,
CAAQS, and attainment classifications for the criteria pollutants are outlined in Table 3.2-2.

a California standards for O3, CO, SO2 (1-hour and 24-hour), NO2, suspended particulate matter (PM10, PM2.5), and visibility-reducing particles
are values that are not to be exceeded. All others are not to be equaled or exceeded. CAAQS are listed in the Table of Standards in Section
70200 of Title 17 of the California Code of Regulations.
b National standards shown are the “primary standards” designed to protect public health. NAAQS (other than O3, NO2, SO2, particulate
matter, and those based on annual averages or annual arithmetic mean) are not to be exceeded more than once per year. The O3 standard
is attained when the fourth highest 8-hour concentration measured at each site in a year, averaged over 3 years, is equal to or less than
3.2 – AIR QUALITY

the standard. For PM10, the 24-hour standard is attained when the expected number of days per calendar year with a 24-hour average
concentration above 150 µg/m3 is equal to or less than 1. For PM2.5, the 24-hour standard is attained when 98% of the daily concentrations,
averaged over 3 years, are equal to or less than the standard.
c On October 1, 2015, the national 8-hour ozone primary and secondary standards were lowered from 0.075 to 0.070 ppm. An area will meet
the standard if the fourth-highest maximum daily 8-hour ozone concentration per year, averaged over three years, is equal to or less than
0.070 ppm. The U.S. Environmental Protection Agency (EPA) will make recommendations on attainment designations by October 1, 2016,
and issue final designations October 1, 2017. Nonattainment areas will have until 2020 to late 2037 to meet the health standard, with
attainment dates varying based on the ozone level in the area.
d On January 9, 2013, the EPA issued a final rule to determine that the Bay Area attains the 24-hour PM2.5 national standard. This EPA rule
suspends key SIP requirements as long as monitoring data continues to show that the Bay Area attains the standard. Despite t his EPA
action, the Bay Area will continue to be designated as “nonattainment” for the national 24-hour PM2.5 standard until such time as the Bay
Area Air Quality Management District (BAAQMD) submits a “redesignation request” and a “maintenance plan” to the EPA, and the EPA
approves the proposed redesignation.
e In December 2012, the EPA strengthened the annual PM2.5 NAAQS from 15.0 to 12.0 μg/m3. In December 2014, the EPA issued final area
designations for the 2012 primary annual PM2.5 NAAQS. Areas designated “unclassifiable/attainment” must continue to take steps to prevent
their air quality from deteriorating to unhealthy levels. The effective date of this standard is April 15, 2015.
f Statewide visibility reducing particle standard (except Lake Tahoe Air Basin): Particles in sufficient amount to produce an extinction
coefficient of 0.23 per kilometer when the relative humidity is less than 70%. This standard is intended to limit the frequency and severity of
visibility impairment due to regional haze and is equivalent to a 10-mile nominal visual range.
Toxic Air Contaminants
The state Air Toxics Program was established in 1983 under AB 1807 (Tanner). The California TAC
list identifies more than 700 pollutants, of which carcinogenic and noncarcinogenic toxicity criteria
have been established for a subset of these pollutants pursuant to the California Health and Safety
Code. In accordance with AB 2728, the state list includes the (federal) HAPs. In 1987, the legislature
enacted the Air Toxics “Hot Spots” Information and Assessment Act of 1987 (AB 2588) to address
public concern over the release of TACs into the atmosphere. AB 2588 requires facilities emitting
toxic substances to provide local air pollution control districts with information that will allow an
assessment of the air toxics problem, identification of air toxics emissions sources, location of
resulting hotspots, notification of the public exposed to significant risk, and development of effective
strategies to reduce potential risks to the public over 5 years. TAC emissions from individual
facilities are quantified and prioritized. High-priority facilities are required to perform health risk
assessments, and if specific thresholds are exceeded, facility operators are required to communicate
the results to the public in the form of notices and public meetings.
In 2000, CARB approved a comprehensive diesel risk reduction plan to reduce diesel emissions from
both new and existing diesel-fueled vehicles and engines (CARB 2000). The regulation is anticipated
to result in an 80% decrease in statewide diesel health risk in 2020 compared with the diesel risk in
2000. Additional regulations apply to new trucks and diesel fuel, including the On-Road Heavy Duty
Diesel Vehicle (In-Use) Regulation, the On-Road Heavy Duty (New) Vehicle Program, the In-Use
Off-Road Diesel Vehicle Regulation, and the New Off-Road Compression-Ignition (Diesel) Engines
and Equipment Program. These regulations and programs have timetables by which manufacturers
must comply and existing operators must upgrade their diesel-powered equipment. There are several
Airborne Toxic Control Measures that reduce diesel emissions, including General Requirements for
In-Use Off-Road Diesel-Fueled Fleets (13 CCR 2449 et seq.) and the Regulation to Reduce

The SFBAAB is designated as a nonattainment area for federal and state O3 and PM2.5 standards.
The SFBAAB is also designated as a nonattainment area for the state PM10 standards. The
SFBAAB is designated as unclassified or attainment for all other criteria air pollutants. Notably,
unclassified areas cannot be classified based on available information as meeting or not meeting
the ambient air quality standard for the pollutant.
Local
Bay Area Air Quality Management District
The BAAQMD is the regional agency responsible for the regulation and enforcement of federal,
state, and local air pollution control regulations in the SFBAAB, where the project site is located.
The clean air strategy of the BAAQMD includes the preparation of plans for the attainment of
ambient air quality standards, adoption and enforcement of rules and regulations concerning
sources of air pollution, issuance of permits for stationary sources of air pollution, inspection of
stationary sources of air pollution and response to citizen complaints, monitoring of ambient air
quality and meteorological conditions, and implementation of programs and regulations required
by the federal and California Clean Air Acts.
On April 19, 2017, the BAAQMD adopted the Spare the Air: Cool the Climate Final 2017 Clean
Air Plan (BAAQMD 2017c). The 2017 Clean Air Plan provides a regional strategy to protect
public health and protect the climate. To protect public health, the 2017 Clean Air Plan includes
all feasible measures to reduce emissions of O3 precursors (ROG and NOx) and reduce O3
transport to neighboring air basins. In addition, the 2017 Clean Air Plan builds on BAAQMD
efforts to reduce PM2.5 and TACs. To protect the climate, the 2017 Clean Air Plan defines a vision
for transitioning the region to a post-carbon economy needed to achieve ambitious greenhouse gas
(GHG) reduction targets for 2030 and 2050 and provides a regional climate protection strategy
that will put the Bay Area on a pathway to achieve those GHG reduction targets.
BAAQMD establishes and administers a program of rules and regulations to attain and maintain
state and national air quality standards and regulations related to TACs. The rules and regulations
that may apply to the project include the following:
• Regulation 2, Rule 1 – Permits. This rule specifies the requirements for authorities to
construct and permits.
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-15
• Regulation 6, Rule 1 – Particulate Matter. This rule limits the quantity of particulate
matter in the atmosphere through the establishment of limitations on emission rates,
concentration, visible emissions, and opacity.
• Regulation 8, Rule 1 – General Provisions. This rule limits the emission of organic
compounds into the atmosphere.
Contra Costa County
The Conservation Element of the Contra Costa County General Plan contains the following air
quality goals and policies that would apply to the project (Contra Costa County 2005):
Goal 8-AA To meet Federal Air Quality Standards for all air pollutants.
Goal 8-AB To continue to support Federal, State, and regional efforts to reduce air pollution in
order to protect human and environmental health.
Goal 8-AC To restore air quality in the area to a more healthful level.

3.2.3 Thresholds of Significance and Methodology
The significance criteria used to evaluate the project impacts to air quality are based on Appendix
G of the California Environmental Quality Act (CEQA) Guidelines. According to Appendix G of
the CEQA Guidelines, a significant impact related to air quality would occur if the project would:
1. Conflict with or obstruct implementation of the applicable air quality plan.
2. Result in a cumulatively considerable new increase of any criteria pollutant for which the project
region is nonattainment under an applicable federal or state ambient air quality standard.
3. Expose sensitive receptors to substantial pollutant concentrations.
4. Result in other emissions (such as those leading to odors) adversely affecting a substantial
number of people.
The BAAQMD adopted updated CEQA Air Quality Guidelines, including new thresholds of
significance, in June 2010 (BAAQMD 2010), and revised them in May 2011. The CEQA Air
Quality Guidelines advise lead agencies on how to evaluate potential air quality impacts, including
establishing quantitative and qualitative thresholds of significance. The BAAQMD resolutions
adopting and revising the significance thresholds in 2011 were set aside by a judicial writ of
mandate on March 5, 2012. In May 2012, the BAAQMD updated its CEQA Air Quality Guidelines
to continue to provide direction on recommended analysis methodologies, but without
recommended quantitative significance thresholds (BAAQMD 2012). On August 13, 2013, the
First District Court of Appeal ordered the trial court to reverse the judgment and upheld the
BAAQMD’s CEQA thresholds. The BAAQMD CEQA Air Quality Guidelines were recently re-
released in May 2017 and include the same thresholds as in the 2010 and 2011 guidelines for
criteria air pollutants, TACs, and GHGs (BAAQMD 2017a). The guidelines also address the
Supreme Court’s December 2015 opinion (California Building Industry Association v. Bay Area
Air Quality Management District [2015] 62 Cal. 4th 369). BAAQMD significance thresholds are
summarized in Table 3.2-3.
In general, the BAAQMD significance thresholds for ROG, NOx, PM10, PM2.5, and CO address
the first two air quality significance criteria. The BAAQMD maintains that these thresholds are
intended to maintain ambient air quality concentrations of these criteria air pollutants below state
and federal standards and to prevent a cumulatively considerable contribution to regional
3.2 – AIR QUALITY

nonattainment with ambient air quality standards. The TAC thresholds (cancer and noncancer
risks) and local CO thresholds address the third significance criterion, and the BAAQMD odors
threshold addresses the fourth significance criterion.

3.2.3.1 Methodology
Construction
Non-Aviation and Aviation-Related Uses
For the land use development component of the project (i.e., aviation and non-aviation uses),
emissions from construction activities were estimated using the California Emissions Estimator
Model (CalEEMod) Version 2016.3.2. CalEEMod is a statewide computer model developed in
cooperation with air districts throughout the state to quantify criteria air pollutant and GHG
emissions (discussed in Section 3.6, Greenhouse Gas Emissions) associated with the construction
and operational activities from a variety of land use projects, such as residential, commercial, and
industrial facilities. CalEEMod input parameters, including the project land use type and size and
construction schedule were based on information provided by the project proponent, or default
model assumptions if project specifics were unavailable.
To estimate project emissions, it was assumed that construction of the project would take
approximately 10 years until build-out, from 2019 through 2028.3 It is assumed that the non-
aviation-related uses would be constructed during the first 5 years, and that non-aviation-related
uses would be constructed during the final 5 years. The analysis contained herein is based on the
following assumptions (duration of phases is approximate):
Non-Aviation Uses
• Site preparation: 2 months (January 2019–February 2019)
• Grading: 5 months (February 2019–July 2019)
• Building construction: 47 months (July 2019–June 2023)
• Paving: 3 months (June 2023–September 2023)
• Architectural coating: 3 months (September 2023–December 2023)
Aviation Uses
• Site preparation: 1 month (January 2024–February 2024)
• Grading: 5 months (February 2024–June 2024)
• Building construction: 48 months (June 2024–July 2028)
3 Note that this is a conservative estimate, as air quality modelling assumes that emissions generally improve over
time. Therefore, estimated emissions would not increase due to delays in the start of construction and may actually
be reduced.
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-19
• Paving: 3 months (July 2028–October 2028)
• Architectural coating: 3 months (October 2028–December 2028)
For the analysis, it was generally assumed that heavy construction equipment would be operating
at the site 5 days per week (22 days per month) during project construction. In addition to
construction equipment operation, emissions from worker trips and vendor trucks (i.e., delivery
trucks) were estimated based on CalEEMod defaults. Vendor trucks transporting building
materials were assumed for building construction. No haul trucks were assumed since demolition
would not be required, and soils would be balanced on site.
Average daily emissions were computed by dividing the total construction emissions by the
number of active construction days. The construction equipment mix and estimated hours of
equipment operation per day used for the air emissions modeling of the project are based on model
defaults, except that a trencher was adding during the grading activity to account for utility
installation. Assumptions are summarized in Table 3.2-4, with additional details regarding
construction assumptions are provided in the modeling output (Appendix C).

Roadway Expansion and Water Infrastructure
Emissions from the roadway expansion and water infrastructure construction activities were
estimated using the Road Construction Emissions Model Version 9.0.0 (SMAQMD 2018). These
construction activities are related to the implementation of mitigation measures for transportation
and utilities (see Section 3.13, Transportation, and Section 3.14, Utilities).
For the purposes of modeling, it was assumed that the roadway expansion and water infrastructure
activities would both commence in January 2019 for durations of 15 days and 35 days,
respectively. In regards to the 0.89-mile roadway expansion, it was estimated that approximately
1 acre total would be disturbed, and that approximately 2,030 cubic yards of asphalt mix would be
imported for paving. In regards to the 2.6-mile pipeline installation, it was estimated that
approximately 1.5 acres total would be disturbed, that approximately 2,974 cubic yards of
demolition debris would be exported, and that 2,965 cubic yards of asphalt mix would be imported
for paving. The analysis contained herein is based on the following assumptions (duration of
phases is approximate):

For the analysis, it was assumed that heavy construction equipment would be operating for 8 hours
per day, 5 days per week (22 days per month) during project construction.
Operations
Emissions from the operational phase of the project were estimated using CalEEMod. Operational year
2029 was assumed based on the first full year of operations. During long-term operations, the project
would generate air pollutants from mobile, energy, and area sources. Traffic trips were estimated based
on the land uses specified in Chapter 2, Project Description, of this Environmental Impact Report
(EIR), and by adjusting default weekday trip rates in CalEEMod to match those included in the
Transportation Impact Analysis Report (GHD 2019) for the land use types.4 The same adjustment
factors used for the weekday trip generation were applied to the default Saturday and Sunday trip rates
in CalEEMod. Increased trip lengths for potential customers based on the rural location of the project,
as well as the project specific vehicle-miles-traveled (VMT) for employees, as described in Chapter
3.13, Transportation, of this EIR. Non-work trip lengths were increased to account for potentially
greater travel distance for deliveries. Project-related traffic was assumed to include a mixture of
vehicles in accordance with the model outputs for traffic. Default CalEEMod assumptions were used
for natural gas combustion and area sources (i.e., landscaping, consumer products, and architectural
coatings for building maintenance). Notably, energy use associated with the airport storage facilities
was assumed to be equivalent to an unrefrigerated warehouse.
In addition, per the CEC Impact Analysis for the 2019 Update to the California Energy Efficiency
Standards for Residential and Non-Residential Buildings, the first-year savings for newly
constructed nonresidential buildings are 197 gigawatt hours of electricity, 76.6 megawatt of
demand, and 0.27 million therms of gas, representing reductions from the 2016 Title 24 standard
of 10.7%, 9%, and 1%, respectively (CEC 2018a). To take into account energy reductions
associated with compliance with 2019 Title 24, the CalEEMod Title 24 electricity and natural gas
values were reduced by 10.7% and 1%, respectively, for all project buildings. The applied
reductions are anticipated to be conservative as in general, nonresidential buildings built to the
2019 standards are anticipated to use an estimated 30% less energy than those built to the 2016
standards (CEC 2018b).

An area is designated as in attainment when it is in compliance with the federal and/or state
standards. These standards are set by the EPA or CARB for the maximum level of a given air
pollutant that can exist in the outdoor air without unacceptable effects on human health or public
welfare with a margin of safety. The project site is located within the SFBAAB, which is
designated non-attainment for the federal 8-hour O3 and 24-hour PM2.5 standards. The area is in
attainment or unclassified for all other federal standards. The area is designated non-attainment for
state standards for 1-hour and 8-hour O3, 24-hour PM10, annual PM10, and annual PM2.5.
On April 19, 2017, the BAAQMD adopted the Spare the Air: Cool the Climate Final 2017 Clean
Air Plan (BAAQMD 2017c). The BAAQMD CEQA Air Quality Guidelines identify a three-step
methodology for determining a project’s consistency with the current Clean Air Plan. If the
responses to these three questions can be concluded in the affirmative and those conclusions are
supported by substantial evidence, then the BAAQMD considers the project to be consistent with
air quality plans prepared for the Bay Area.
The first question to be assessed in this methodology is “does the project support the goals of the
Air Quality Plan?” The BAAQMD-recommended measure for determining project support for
these goals is consistency with BAAQMD thresholds of significance. If a project would not result
in significant and unavoidable air quality impacts, after the application of all feasible mitigation
measures, the project would be consistent with the goals of the 2017 Clean Air Plan. As indicated
in the following discussion with regard to air quality Impact 3.2-2 and Impact 3.2-3, the project
would result in potentially significant operational emission impacts associated with NOx and PM10,
primarily from mobile sources. Therefore, the project would be considered to potentially conflict
with or obstruct implementation of the current Clean Air Plan.
The second question to be assessed in this consistency methodology is “does the project include
applicable control measures from the Clean Air Plan?” The 2017 Clean Air Plan contains 85
control measures aimed at reducing air pollution in the Bay Area. Projects that incorporate all
feasible air quality plan control measures are considered consistent with the Clean Air Plan. The
control strategies of the 2017 Clean Air Plan include measures in the categories of stationary
sources, the transportation sector, the buildings sector, the energy sector, the agriculture sector,
natural and working lands, the waste sector, the water sector, and super-GHG pollutant measures.
Depending on the control measure, the tools for implementation include leveraging the BAAQMD
rules and permitting authority, regional coordination and funding, working with local governments
to facilitate best policies in building codes, outreach and education, and advocacy strategies. The
project would comply with all applicable BAAQMD rules and would meet state standards and/or
local building codes and would not conflict with any applicable control measures from the 2017
Clean Air Plan.
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-25
The third question to be assessed in this consistency methodology is “does the project disrupt or
hinder implementation of any control measures from the Clean Air Plan?” Examples of how a
project may cause the disruption or delay of control measures include a project that precludes an
extension of a transit line or bike path or proposes excessive parking beyond parking requirements.
The project would not create any barriers or impediments to planned or future improvements to
transit or bicycle facilities in the area, nor would it include excessive parking. Therefore, the
project would not hinder implementation of 2017 Clean Air Plan control measures.
In summary, based on the substantial increase in operational emissions of NOx and PM10, the
project would potentially conflict with or obstruct implementation of the 2017 Clean Air Plan.
This is a potentially significant impact.
Impact 3.2-2. The project would result in a cumulatively considerable net increase of criteria
pollutants for which the project region is in nonattainment under an applicable
Federal or State ambient air quality standard. (Potentially Significant)
Past, present, and future development projects may contribute to the SFBAAB adverse air quality
impacts on a cumulative basis. Per BAAQMD’s CEQA Air Quality Guidelines, by its nature air
pollution is largely a cumulative impact; no single project is sufficient in size to, by itself, result
in nonattainment of ambient air quality standards. In developing thresholds of significance for air
pollutants, BAAQMD considered the emission levels for which a project’s individual emissions
would be cumulatively considerable. If a project exceeds the identified significance thresholds, its
emissions would be considered cumulatively considerable, resulting in a significant adverse air
quality impact to the region’s existing air quality conditions. Therefore, if the project’s emissions
are below the BAAQMD thresholds or screening criteria, then the project would not result in a
cumulatively considerable net increase of any criteria air pollutant.
Construction
The project would potentially involve the construction and operation of up to 274,000 square feet of
logistics/warehouse/distribution buildings, 213,000 square feet of light industry/business park, 81,000
square feet of office uses, 91,000 square feet of commercial uses, 128,000 square feet of airport storage,
154,000 square feet of aviation use buildings, and associated parking. In addition, the project would
require 0.89 miles of roadway expansion and 2.6 miles of water infrastructure installation. Construction
is anticipated to begin in 2019 and take approximately 10 years to complete. Sources of emissions
would include off-road construction equipment exhaust, on-road vehicle exhaust and entrained road
dust (i.e., material delivery trucks and worker vehicles), fugitive dust associated with site preparation
and grading activities, and paving and architectural coating activities. Detailed assumptions associated
with project construction are included in Appendix C.

Average daily emissions were computed by dividing the total construction emissions by the
number of active construction days, which were then compared to the BAAQMD construction

The values shown are average daily emissions based on total overall tons of construction emissions associated with the development of the non-
aviation and aviation uses, roadway expansion, and water infrastructure installation, converted to pounds, and divided by 2,609 active workdays.
As shown in Table 3.2-6, construction of the project would not exceed BAAQMD significance
thresholds. Criteria air pollutant emissions during construction would be less than significant.6
Although the BAAQMD does not have a quantitative significance threshold for fugitive dust, the
BAAQMD’s CEQA Guidelines recommend that projects determine the significance of fugitive
dust through application of best management practices. Without adequate controls, fugitive dust
during construction could be a short-term, but potentially significant impact.
Operations
Operation of the project would generate criteria pollutant (including ROG, NOx, PM10, and PM2.5)
emissions from mobile sources (vehicular traffic), area sources (consumer products, architectural
coatings, landscaping equipment), and energy sources (natural gas appliances, space and water
heating). CalEEMod was used to estimate daily emissions from project-related operational
sources, as previously described in Section 3.2.3, Thresholds of Significance and Methodology.
5 Fuel combustion during construction and operations would also result in the generation of sulfur dioxide (SO 2)
and CO. These values are included in Appendix C. However, since the SFBAAB is in attainment of these
pollutants, the BAAQMD has not established a quantitative mass-significance threshold for comparison and are
not included in the project-generated emissions tables in this document. Notably, the BAAQMD does have
screening criteria for operational localized CO, which are discussed in more detail below.
6 Construction emissions are based on the assumption of a five -year construction period for all non-aviation uses.
It should be noted that the buildout of the warehousing component, approximately 274,000 square feet of building
space, could be accomplished in a two-year period without exceeding the significance thresholds. The estimated
unmitigated construction emissions for the warehousing component would be ROG 10.6 lbs./day, NOx 48.2
lbs./day, PM10 1.4 lbs./day, and PM2.5 1.3 lbs./day.

As indicated in Table 3.2-7, project-related operational emissions of ROG and PM2.5 would not
exceed the BAAQMD significance thresholds during operations. However, project-related
emissions of NOx and PM10, primarily from mobile sources, would exceed the BAAQMD
significance thresholds. As such, the project would have a potentially significant impact in
relation to regional operational emissions.
Impact 3.2-3. The project could expose sensitive receptors to substantial pollutant
concentrations. (Potentially Significant)
Toxic Air Contaminants
The BAAQMD has adopted project and cumulative thresholds for three risk-related air quality
indicators to sensitive receptors: cancer risks, noncancer health effects, and increases in ambient
air concentrations of PM2.5. These impacts are addressed on a localized, rather than regional,
basis in relation to sensitive receptors identified for the project. Sensitive receptors are groups of
individuals, including children, older adults, the acutely ill, and the chronically ill, that may be
more susceptible to health risks due to chemical exposure. Sensitive-receptor population groups
are likely to be located at hospitals, medical clinics, schools, playgrounds, childcare centers,
residences, and retirement homes. Proximate sensitive receptors to the project include several
residences along Byron Hot Springs Road, the nearest of which is located approximately 300 feet
to the east of the project.

TACs and PM2.5 can cause cancer and noncancer chronic and acute health impacts such as birth
defects, neurological damage, asthma, bronchitis, and genetic damage, and short-term acute
affects such as eye watering, respiratory irritation, running nose, throat pain, and headaches.
State law has established the framework for California’s TAC identification and control
program, which is generally more stringent than the federal program and aimed at TACs that are
a problem in California. The state currently regulates hundreds of compounds as TACs,
including the federal HAPs, and continues to adopt control measures for sources of these TACs.
CARB has classified DPM as a TAC. The following measures are required by state law to reduce
DPM emissions:
• Fleet owners of mobile construction equipment are subject to the CARB Regulation for In-
Use Off-Road Diesel Vehicles (13 CCR 2449) to reduce DPM and criteria pollutant
emissions from in-use (existing) off-road diesel-fueled vehicles.
• All commercial diesel vehicles are subject to Title 13 of the California Code of
Regulations, Section 2485, limiting engine idling time. Idling of heavy-duty diesel
construction equipment and trucks during loading and unloading must be limited to 5
minutes; electric auxiliary power units should be used whenever possible.
The greatest potential for TAC emissions during construction would be DPM emissions from
heavy equipment operations and heavy-duty trucks. Since the project construction would be
phased based on market conditions, with activities in multiple areas across the project site, the
project would not require the extensive use of heavy-duty construction equipment or diesel
trucks in any one location over the duration of development, which would limit the exposure of
any proximate individual sensitive receptor to TACs. However, based on the proximity of
existing sensitive receptors to project construction, this impact would be potentially significant.
Regarding long-term operations, the project would include uses that would likely generate
substantial diesel truck traffic, including the logistics/warehouse/distribution buildings. In
regards to distribution centers, the CARB Air Quality and Land Use Handbook (CARB 2005)
has the following recommendations:
• Avoid siting new sensitive land uses within 1,000 feet of a distribution center that:
o Accommodates more than 100 trucks per day, or
o Accommodates more than 40 trucks with operating transport refrigeration units (TRUs)
per day, or
o Where TRU operations exceed 300 hours per week.
Based on preliminary site plans, it is possible that the project would result in distribution (or
similar) facilities within 1,000 feet of existing off-site residential receptors. Since operational

parameters, such as truck trip generation and TRU usage, are unknown at this time, the potential
health risk from exposure to DPM would be speculative. However, based on the proposed land
uses and the proximity to sensitive receptors, this impact would be potentially significant.
Carbon Monoxide Hotspots
According to the BAAQMD, a proposed project would result in a less-than-significant impact to
localized CO concentrations if the following screening criteria are met (BAAQMD 2017a):
1. The project is consistent with an applicable congestion management program established
by the county congestion management agency for designated roads or highways, regional
transportation plan, and local congestion management agency plans.
2. The project traffic would not increase traffic volumes at affected intersections to more than
44,000 vehicles per hour.
3. The project traffic would not increase traffic volumes at affected intersections to more than
24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited (e.g.,
tunnel, parking garage, bridge underpass, natural or urban street canyon, below-grade roadway).
The project would generate new traffic trips, but not to a level that would result in an exceedance
of the BAAQMD screening criteria. Accordingly, project-related traffic would not exceed CO
standards and therefore, no further analysis was conducted for CO impacts. This CO emissions
impact would be less than significant on a project-level and cumulative basis.
Health Impacts of Other Criteria Air Pollutants
Construction and operation of the project would not result in emissions that exceed the BAAQMD
emission thresholds for any criteria air pollutants.
ROG and NOx are precursors to O3, for which the SFBAAB is designated as nonattainment with
respect to the NAAQS and CAAQS. The health effects associated with O3 are generally associated
with reduced lung function. The contribution of ROG and NOx to regional ambient O3
concentrations is the result of complex photochemistry. The increases in O3 concentrations in the
SFBAAB due to O3 precursor emissions tend to be found downwind from the source locations to
allow time for the photochemical reactions to occur. However, the potential for exacerbating
excessive O3 concentrations would also depend on the time of year that the ROG emissions would
occur because exceedances of the O3 NAAQS and CAAQS tend to occur between April and
October when solar radiation is highest. The holistic effect of a single project’s emissions of O3
precursors is speculative due to the lack of quantitative methods to assess this impact. That being
said, because the project would exceed the BAAQMD NOx threshold during operations, the project
could contribute to health effects associated with O3.
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-30
Health effects associated with NOx and NO2 include lung irritation and enhanced allergic responses
(see Section 3.2.1.2) (CARB 2019a). Although Project-related NOx emissions would exceed the
BAAQMD mass daily thresholds during operations, because the SFBAAB is a designated attainment
area for NO2 (and NO2 is a constituent of NOx) and the existing NO2 concentrations in the area are
well below the NAAQS and CAAQS standards,7 it is not anticipated that the project would cause an
exceedance of the NAAQS and CAAQS for NO2 or result in potential health effects associated with
NO2 and NOx. Nonetheless, because the project would exceed the BAAQMD NOx threshold during
operations, the project could contribute to health effects associated with NOx and NO2.
Health effects associated with CO include chest pain in patients with heart disease, headache, light-
headedness, and reduced mental alertness (see Section 3.2.1.2) (CARB 2019b). CO tends to be a
localized impact associated with congested intersections. The potential for CO hotspots was
discussed above and determined to be less than significant. Thus, the project’s CO emissions
would not contribute to significant health effects associated with CO.
Health effects associated with PM10 include premature death and hospitalization, primarily for
worsening of respiratory disease (see Section 3.2.1.2) (CARB 2017). Operation of the project would
exceed the BAAMQD threshold for PM10. As such, the project would potentially contribute to
exceedances of the NAAQS and CAAQS for particulate matter and obstruct the SFBAAB from
coming into attainment for this pollutant. Because the project has the potential to contribute substantial
particulate matter during operation, the project could result in associated health effects.
The California Supreme Court’s Sierra Club v. County of Fresno (2018) 6 Cal. 5th 502 decision
(referred to herein as the Friant Ranch decision) (issued on December 24, 2018), addresses the need to
correlate mass emission values for criteria air pollutants to specific health consequences, and contains
the following direction from the California Supreme Court: “The Environmental Impact Report (EIR)
must provide an adequate analysis to inform the public how its bare numbers translate to create
potential adverse impacts or it must explain what the agency does know and why, given existing
scientific constraints, it cannot translate potential health impacts further” (Italics original). Currently,
BAAQMD, CARB, and EPA have not approved a quantitative method to reliably, meaningfully,
and consistently translate the mass emission estimates for the criteria air pollutants resulting from
the project to specific health effects. In addition, there are numerous scientific and technological
complexities associated with correlating criteria air pollutant emissions from an individual project
to specific health effects or potential additional nonattainment days.
In connection with the judicial proceedings culminating in issuance of the Friant Ranch decision,
the South Coast Air Quality Management District (SCAQMD) and the San Joaquin Valley Air
Pollution Control District (SJVAPCD) filed amicus briefs attesting to the extreme difficulty of
7 See Table 3.2-1, which shows that ambient concentrations of NO2 at the Livermore-Patterson Pass Road
monitoring station have not exceeded the NAAQS or CAAQS between 2015 and 2017.
3.2 – AIR QUALITY

correlating an individual project’s criteria air pollutant emissions to specific health impacts. Both
the SJVAPCD and the SCAQMD have among the most sophisticated air quality modeling and
health impact evaluation capabilities of the air districts in the state. The key, relevant points from
the SCAQMD and SJVAPCD briefs is summarized herein.
In requiring a health impact type of analysis for criteria air pollutants, it is important to understand how
O3 and PM is formed, dispersed, and regulated. The formation of O3 and PM in the atmosphere, as
secondary pollutants,8 involves complex chemical and physical interactions of multiple pollutants
from natural and anthropogenic sources. The O3 reaction is self-perpetuating (or catalytic) in the
presence of sunlight because NO2 is photochemically reformed from nitric oxide (NO). In this
way, O3 is controlled by both NOx and VOC emissions (NRC 2005). The complexity of these
interacting cycles of pollutants means that incremental decreases in one emission may not result
in proportional decreases in O3 (NRC 2005). Although these reactions and interactions are well
understood, variability in emission source operations and meteorology creates uncertainty in the
modeled O3 concentrations to which downwind populations may be exposed (NRC 2005). Once
formed, O3 can be transported long distances by wind and due to atmospheric transport,
contributions of precursors from the surrounding region can also be important (EPA 2008).
Because of the complexity of O3 formation, a specific tonnage amount of VOCs or NOX emitted
in a particular area does not equate to a particular concentration of O3 in that area (SJVAPCD
2015). PM can be divided into two categories: directly emitted PM and secondary PM. Secondary
PM, like O3, is formed via complex chemical reactions in the atmosphere between precursor
chemicals such as SOx and NOx (SJVAPCD 2015). Because of the complexity of secondary PM
formation, including the potential to be transported long distances by wind, the tonnage of PM-
forming precursor emissions in an area does not necessarily result in an equivalent concentration
of secondary PM in that area (SJVAPCD 2015). This is especially true for individual projects, like
the project, where project-generated criteria air pollutant emissions are not derived from a single
"point source," but from construction equipment and mobile sources (passenger cars and trucks)
driving to, from and around the project site.
Another important technical nuance is that health effects from air pollutants are related to the
concentration of the air pollutant that an individual is exposed to, not necessarily the individual
mass quantity of emissions associated with an individual project. For example, health effects from
O3 are correlated with increases in the ambient level of O3 in the air a person breathes (SCAQMD
2015). However, it takes a large amount of additional precursor emissions to cause a modeled
increase in ambient O3 levels over an entire region (SCAQMD 2015). The lack of link between
the tonnage of precursor pollutants and the concentration of O3 and PM2.5 formed is important
because it is not necessarily the tonnage of precursor pollutants that causes human health effects;
rather, it is the concentration of resulting O3 that causes these effects (SJVAPCD 2015). Indeed,
8 Air pollutants formed through chemical reactions in the atmosphere are referred to as secondary pollutants.
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-32
the ambient air quality standards, which are statutorily required to be set by EPA at levels that are
requisite to protect the public health, are established as concentrations of O3 and PM2.5 and not as
tonnages of their precursor pollutants (EPA 2018c). Because the ambient air quality standards are
focused on achieving a particular concentration region-wide, the tools and plans for attaining the
ambient air quality standards are regional in nature. For CEQA analyses, project-generated
emissions are typically estimated in pounds per day or tons per year and compared to mass daily
or annual emission thresholds. While CEQA thresholds are established at levels that the air basin
can accommodate without affecting the attainment date for the AAQS, even if a project exceeds
established CEQA significance thresholds, this does not mean that one can easily determine the
concentration of O3 or PM that will be created at or near the project site on a particular day or
month of the year, or what specific health impacts will occur (SJVAPCD 2015).
In regard to regional concentrations and air basin attainment, the SJVAPCD emphasized that
attempting to identify a change in background pollutant concentrations that can be attributed to a single
project, even one as large as the entire Friant Ranch Specific Plan, is a theoretical exercise. The
SJVAPCD brief noted that it “would be extremely difficult to model the impact on NAAQS attainment
that the emissions from the Friant Ranch project may have” (SJVAPCD 2015). The situation is further
complicated by the fact that background concentrations of regional pollutants are not uniform either
temporally or geographically throughout an air basin but are constantly fluctuating based upon
meteorology and other environmental factors. SJVAPCD noted that the currently available modeling
tools are equipped to model the impact of all emission sources in the San Joaquin Valley Air Basin on
attainment (SJVAPCD 2015). The SJVAPCD brief then indicated that, “Running the photochemical
grid model used for predicting O3 attainment with the emissions solely from the Friant Ranch project
(which equate to less than one-tenth of one percent of the total NOx and VOC in the Valley) is not
likely to yield valid information given the relative scale involved” (SJVAPCD 2015).
SCAQMD and SJVAPCD have indicated that it is not feasible to quantify project-level health
impacts based on existing modeling (SCAQMD 2015; SJVAPCD 2015). Even if a metric could
be calculated, it would not be reliable because the models are equipped to model the impact of all
emission sources in an air basin on attainment and would likely not yield valid information or a
measurable increase in O3 concentrations sufficient to accurately quantify O3-related health
impacts for an individual project.
Nonetheless, following the Supreme Court’s Friant Ranch decision, some EIRs where estimated
criteria air pollutant emissions exceeded applicable air district thresholds have included a quantitative
analysis of potential project-generated health effects using a combination of a regional photochemical
grid model (PGM)9 and the EPA Benefits Mapping and Analysis Program (BenMAP or BenMAP–
9 The first step in the publicly available HIAs includes running a regional PGM, such as the Community Multiscale
Air Quality (CMAQ) model or the Comprehensive Air Quality M odel with extensions (CAMx) to estimate the

Community Edition [CE]).10 To date, the publicly available health impact assessments (HIAs)
typically present results in terms of an increase in health incidences and/or the increase in
background health incidence for various health outcomes resulting from the project’s estimated
increase in concentrations of O3 and PM2.5, and have each concluded that the potential health
impacts are negligible and potentially within the models’ margin of error.11
As explained in the SJVAPCD brief and noted previously, running the PGM used for predicting O3
attainment with the emissions solely from an individual project like the Friant Ranch project or the
proposed project is not likely to yield valid information given the relative scale involved. The
publicly available HIAs support the SJVAPCD’s brief contention that consistent, reliable, and
meaningful results may not be provided by methods applied at this time. Accordingly, additional
work in the industry and more importantly, air district participation, is needed to develop a more
meaningful analysis to correlate project-level mass criteria air pollutant emissions and health effects
for decision makers and the public. Furthermore, at the time of writing, no HIA has concluded that
health effects estimated using the PGM and BenMAP approach are substantial provided that the
estimated project-generated incidences represent a very small percentage of the number of
background incidences, potentially within the models’ margin of error.
In summary, operation of the project could result in exceedances of the BAAQMD significance
thresholds for NOx and PM10 and the project would potentially result in health effects associated
with those pollutants. Because construction of the project would not exceed any BAAQMD
thresholds, and operation of the project would not exceed the MDAQMD thresholds for ROG or
PM2.5, and because the BAAQMD thresholds are based on levels that the SFBAAB can
accommodate without affecting the attainment date for the AAQS and the AAQS are established
to protect public health and welfare, the project is not anticipated to result in health effects
associated with ROG or PM2.5.
pollutants. Air districts use photochemical air quality models for regional air quality planning. These
photochemical models are large-scale air quality models that simulate the changes of pollutant concentrations in
the atmosphere using a set of mathematical equations characterizing the chemical and physical processes in the
atmosphere (EPA 2017).
10 After estimating the increase in concentrations of O3 and PM2.5, the second step in the five examples includes use
of BenMAP or BenMAP-CE to estimate the resulting associated health effects. BenMAP estimates the number
of health incidences resulting from changes in air pollution concentrations (EPA 2018d). The health impact
function in BenMAP-CE incorporates four key sources of data: (i) modeled or monitored air quality changes, (ii)
population, (iii) baseline incidence rates, and (iv) an effect estimate. All of the five example HIAs focused on O3
and PM2.5.

Notably, there are numerous scientific and technological complexities associated with correlating
criteria air pollutant emissions from an individual project to specific health effects or potential
additional nonattainment days, and methods available to quantitatively evaluate health effects may
not be appropriate to apply to emissions associated with the project, which cannot be estimated
with a high-level of accuracy. Notwithstanding, because operation of the project could result in
exceedances of BAAQMD significance thresholds for NOx and PM10, even after implementation
of MM-AQ-3, the potential health effects associated with criteria air pollutants are conservatively
considered significant and unavoidable.
Impact 3.2-4. The project would not result in other emissions (such as those leading to odors)
adversely affecting a substantial number of people. (Less than Significant)
BAAQMD has identified typical sources of odor in the CEQA Air Quality Guidelines, a few
examples of which include manufacturing plants, rendering plants, coffee roasters, wastewater
treatment plants, sanitary landfills, and solid waste transfer stations. While sources that generate
objectionable odors must comply with air quality regulations, the public’s sensitivity to locally
produced odors often exceeds regulatory thresholds.
Odors would be potentially generated from vehicles and equipment exhaust emissions during
construction of the project. Potential odors produced during construction would be attributable to
concentrations of unburned hydrocarbons from tailpipes of construction equipment. Such odors would
disperse rapidly from the project site and generally occur at magnitudes that would not affect
substantial numbers of people. In regards to long-term operations, the project uses are not among the
land uses that the BAAQMD has identified as a prime source of odors discussed above. Therefore,
project-related odor impacts during construction and operations would be less than significant.
3.2.5 Mitigation Measures
MM-AQ-1 The project contractor would be required as conditions of approval to implement
the following best management practices that are required of all projects:
• All exposed surfaces (e.g., parking areas, staging areas, soil piles,
graded areas, and unpaved acces s roads) shall be watered two times per
day.
• All haul trucks transporting soil, sand, or other loose material off site
shall be covered.
• All visible mud or dirt track -out onto adjacent public roads shall be

• All construction equipment shall be maintained and properly tuned in
accordance with manufacturer’s specifications. All equipment shall be
checked by a certi fied mechanic and determined to be running in proper
condition prior to operation.
• 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 BAAQMD’s
phone number shall also be visible to ensure compliance with
applicable regulations.
MM-AQ-2 The project shall implement the following measures for all facilities in order to
reduce operational air pollutant emissions to the extent feasible. To the extent that
the measures below are addressed by MM-AQ-4 as part of any health risk
assessment that is prepared, the measures in MM-AQ-4 shall take precedence.
• Only haul trucks meeting model year 2010 engine emission standards shall
be used for the on-road transport of materials to and from the project site.
• Legible, durable, weather-proof signs shall be placed at truck access gates,
loading docks, and truck parking areas that identify applicable anti-idling
regulations. At a minimum, each sign shall include: 1) instructions for truck
drivers to shut off engines when not in use; 2) instructions for drivers of

• Conduit shall be installed to tractor trailer parking areas in logical locations
determined by the facility operator during construction document plan check,
for the purpose of accommodating the future installation of EV truck charging
stations at such time this technology becomes commercially available.
MM-AQ-3 For non-aviation facilities with construction proposed within 1,000 feet of off-site
residential receptors, a construction health risk assessment shall be prepared to assess
exposure of existing sensitive receptors to toxic air contaminants (TACs) during
project construction. If the health risk assessment determines that cancer and non-
cancer impacts would be less than significant, no additional measures are needed.
Alternatively, the results of the health risk assessment may necessitate implementation
of TAC exposure reduction strategies in order to reduce potential risk to less-than-
significant levels, which could include, but are not limited to, the following:
• Portable equipment used during construction shall be powered by
electricity from the grid instead of diesel -powered generators, to the
maximum amount feasible.
• Equip heavy-duty diesel-powered construction equipment with Tier 4
Interim or better diesel engines, except where Tier 4 Interim or better
engines are not available for specific construction equipment. Contra Costa
County shall verify and approve all pieces within the construction fleet that
would not meet Tier 4 Interim standards. At a minimum, Tier 3 engines
shall be required if Tier 4 engines are not available.
• All conditions of approval/mitigations shall be placed on construction
drawings and part of any construction contract. Physical copies of the plans
shall be available at the on-site job trailer.
MM-AQ-4 For non-aviation uses, a health risk assessment of long-term operations shall be
prepared if the proposed facility is within 1,000 feet of off-site residential receptors
and would result in any of the following:
• Accommodate more than 100 trucks per day, or
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-37
• Accommodate more than 40 trucks with operating transport refrigeration
units (TRUs) per day, or
• Where TRU operations exceed 300 hours per week.
Results of the health risk assessment may necessitate implementation of toxic
air contaminant (TAC ) exposure reduction strategies in order to reduce
potential risk to less -than -significant levels , which could include , but are not
limited to , the following:
• Idling of diesel equipment of any type shall be strictly prohibited at the
premises. The facility operator shall inform all business partners, visitors,
etc., of the Zero-Idling Rule in effect for the subject property and area
streets. Highly visible signs prohibiting idling shall be posted at each
entrance and exist. Violators of this zero-idling rule are subject to fines and
or criminal charges.
• Within 90 days of occupying the space, the facility operator shall submit to
the Airports Division and the Department of Conservation and
Development (DCD) the first of an annual inventory of all equipment that
generates criteria pollutant, TACs, and greenhouse gas (GHG) emissions
operated at the subject location throughout the life of the project up to year
2035. The equipment inventory shall include the year, make, and model of
the equipment that was used in the previous year, including annual hours of
operation for each piece of equipment, including but not limited to heavy-
duty drayage and non-drayage trucks, yard equipment, bulk material
handling equipment (forklifts, etc.), and any other type of material handling
equipment. The purpose of the inventory is to track emissions/equipment
and to assist in technology reviews.
• The facility operator shall purchase/lease or otherwise acquire zero-
emission vehicles/equipment (including: light/heavy duty trucks, drayage
equipment, forklifts, and generators) when commercially available as the
attrition of gasoline/diesel equipment occurs. The facility operator is
encouraged to utilize any or all of the funding opportunities offered by
California Air Resources Board (CARB) and other available programs. The
availability of zero-emission equipment shall be determined in a joint effort
between the Airports Division and the facility operator as part of an annual
technology review.
• The facility operator shall adhere to the findings of the annual technologies
review for reducing air emissions as part of the County Climate Action Plan
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-38
and long-range sustainability goals, which encourage property owners and
tenants to use cleaner technologies over time as they become available. A
priority goal of the review shall be the replacement of older equipment in
operation at the subject site that generates the highest levels of criteria
pollutant, TAC, and GHG emissions. The equipment to be replaced shall be
determined based on the level of emissions and cost-effectiveness of the
emissions reduction (e.g., biggest reduction per dollar), and identify
implementation mechanisms including, but not limited to, tenant-based
improvements, grant programs, or a combination thereof, based on
regulatory requirements and the feasibility analysis performed by the
Airports Division. The Carl Moyer Program, or similar cost-effectiveness
criteria, shall be used to assess the economic feasibility (e.g., cos t
effectiveness) of the identified new technologies. Zero-emission equipment
employed pursuant to this mitigation may be replaced by other technologies
or other types of equipment as long as the replacement equipment achieves
the same or greater criteria pollutant, TAC, and GHG emission reductions
as compared to the equipment identified as part of the technology review.
• Every California-based TRU and electronic-TRU (E-TRU) operational at
the site must be registered with the Air Resource Board Equipment
Registration and shall be labeled with a CARB Identification Number.
Facility operators handling TRUs shall install charging infrastructure and
encourage E-TRUs on site and require those non-E-TRUs to plug in while
stationary at the facility.
• Prior to occupancy the facility operator shall demonstrate compliance with
all newly adopted Ordinances/Statutes/Plans and requirements passed by all
responsible agencies in relation to traffic, diesel emissions and air quality
improvement measures.
3.2.6 Level of Significance After Mitigation
By exceeding the BAAQMD operational thresholds for NOx and PM10, despite implementation of
feasible mitigation measures, described below, the project would conflict with the 2017 Clean Air
Plan and Impact 3.2-1 would be significant and unavoidable.
Implementation of MM-AQ-1 would reduce the effect of fugitive dust to less than significant.
Although mitigation measures have been recommended to minimize operational-related air quality
impacts, per MM-AQ-2, no feasible mitigation measures or project design features beyond those
already identified exist that would reduce these emissions to levels that are less than significant.
The majority of the project’s NOX and PM10 emissions are derived from vehicle usage, which
3.2 – AIR QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.2-39
neither the project applicant nor the County can substantively or materially affect reductions in
project mobile source emissions beyond what is already required. Therefore, even with the
incorporation of mitigation, long-term impacts associated with a cumulatively considerable net
increase of criteria pollutants for which the project region is non-attainment remain significant.
Therefore Impact 3.2-2 would be significant and unavoidable.
Implementation of MM-AQ-3 and MM-AQ-4 would reduce the potential exposure of existing
sensitive residential receptors to TACs from project construction and operations and would ensure
that health risk levels would be below the BAAQMD thresholds. Thus, Impact 3.2-3 would be less
than significant after mitigation.
3.2.7 Cumulative Impacts
Cumulative air quality impacts are addressed in Impact 3.2-2, above. The project would result in
a cumulatively considerable impact to air quality.

3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269

3.3 BIOLOGICAL RESOURCES
This section describes the existing biological resources of the Byron Airport Development
Program (project) site, identifies associated regulatory requirements, evaluates potential impacts,
and identifies mitigation measures to reduce the project’s potentially significant impacts to less-
than-significant levels. This section is based on the Biological Resources Assessment for the Byron
Airport Project prepared by Dudek in December 2018 (Appendix D).
3.3.1 Existing Conditions
This section describes the existing conditions in the project site and also identifies the resources
that could be affected by construction and/or operation of the project.
3.3.1.1 Project Location
The project site is located in southeastern Contra Costa County (County), approximately 2.5 miles
south of the community of Byron, California. The project site consists of the Byron Airport
property south of Armstrong Road, which is approximately 1,307 acres, and the 11.7-acre parcel
located between the airport property and the Bethany Irrigation District Canal, for a total of 1,319
acres. The airport also owns an additional 120 acres north of Armstrong Road that is not considered
part of the project site. The project site is relatively flat land that contains several buildings, two
nonintersecting runways each with a parallel taxiway, several connector taxiways, and aircraft
storage areas. The airport is located on the western edge of the flat Central Valley agricultural
lands, giving way to rolling hills and grasslands west of the airport. Clifton Court Forebay is
located less than 2 miles east of the site, Bethany Reservoir is approximately 3 miles to the south,
and Los Vaqueros Reservoir is 5 miles to the west. The project site is characterized as open
grassland combined with developed/disturbed areas. Vegetation surrounding the site consists of
ruderal ornamental landscaping, ruderal grassland adjacent to runways, annual grassland with
scattered vernal pools and seasonal wetlands, and alkali grasslands. The project site historically
supported agricultural fields from at least 1949 until 1966, when a portion of it was graded to
establish a smaller airfield. Approximately 814 acres of airport property to the south and west of
the airfield (south of Armstrong Road) are set aside as for habitat management/conservation
(Conservation lands).
The following sections consider the biological study area, which is based on the potential development
area identified in the Byron Airport Master Plan (Contra Costa County 2005a). Within this larger study
area, the proposed project considers development in two areas: a 46.6-acre non-aviation area east of
the main runway, and a 23.5-acre aviation area adjacent to the existing aviation facilities west of the
main runway (Figure 3.3-1, Field-Verified Land Cover Map). The areas shown as “Development
Reserve” on Figure 3.3-1 were considered for potential development in the Byron Airport Master Plan
but have since been removed from the proposed project.

3.3.1.2 Vegetation Communities and Land Cover Types
Four terrestrial, and four aquatic land cover types exist in the study area, as shown in Figure 3.3-1
and Table 3.3-1. The majority of the area is made up of annual grassland habitat with urban areas
that include the buildings, paved areas, and ornamental landscaping associated with operation of
the airport. The remaining portion of the project site consists of annual and alkali grasslands
interspersed with seasonal and alkali wetlands, as well as vernal pools. Seasonal wetlands are
prevalent in the annual grassland in the northwestern and western areas of the project site. Several
drainages also cross through the project site. These drainages appear to be intermittent in nature,
carrying water only during the wet season. These land cover types are described in detail below.

Grasslands
Annual Grasslands
Annual grassland is the predominant vegetation community mapped during the surveys and is
present throughout the site. Annual grassland within the site is dominated by a dense to sparse
cover of annual, non-native grasses and forbs. Common species include soft brome (Bromus
hordeaceus and B. diandrus), wild oat (Avena fatua), mouse barley (Hordeum murinum), filaree
(Erodium spp.), and others. However, native species are also present in this grassland, including
bulbs (Dichelostemma spp. and Brodiaea spp.), legumes such lupines (Lupinus nanus and L.
succulentus), and some grasses such as blue wildrye (Elymus glaucus). Ruderal species are also
often present in grasslands, especially along the margins of grasslands and in areas that have been
historically disturbed.
Dominant species observed on site within the grassland community included slender oat (Avena
barbata), ripgut brome (Bromus diandrus), and soft brome. Several ruderal and other non-native
species were also present, including curly dock (Rumex crispus) and garden vetch (Vicia sativa).
Alkali Grasslands
Alkali grasslands were similar in species composition to annual grasslands except for the decreased
cover of non-native grasses and increased cover of species with an affinity for alkaline soils.
Species adapted for greater alkalinity observed in alkali grasslands on site included salt grass
(Distichlis spicata), alkali heath (Frankenia salina), wild barley (Hordeum spp.), and a few
scattered stands of iodine bushes (Allenrolfea occidentalis).
Ruderal Grasslands
Ruderal grasslands were mapped in association with the airport facilities. These areas appear to be
maintained on an annual or semi-annual basis to control wildlife and weeds within the airport
enclosure. Dominant species in the ruderal grassland are similar to those in the annual grassland;
however, the occurrence of native grasses and forbs is much reduced. Black mustard (Brassica
nigra), field mustard (B. rapa), wild radish (Raphanus sativa), and Russian thistle (Salsola tragus)
were common amongst the wild oats in this habitat type.
Developed
Urban
Urban areas are those dominated by human-made structures. In the project site, urban areas consist
of roadways, runways, hangars, other airport buildings, and a residence and shop. Vegetation in
these areas is sparse to absent, consisting primarily of cultivated plants in planters.
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-4
Wetlands
Seasonal Wetlands
Seasonal wetlands were prevalent in the annual grassland in the northwestern and western areas of
the project site. Species commonly noted within the seasonal wetlands included Italian rye grass
(Festuca perennis), seaside barley (Hordeum marinum), small fescue (Festuca microstachys), and
perennial pepperweed (Lepidium latifolium). Several small stands of red willow (Salix laevigata)
were also noted along the margins of the seasonal wetlands in the western portion of the site.
Alkali Wetlands
Alkali wetlands consisted of seasonal wetlands within alkali grassland. The alkali wetlands
generally consisted of barren areas where water remains inundated for prolonged periods of time
during the growing season. Species similar to those found in seasonal wetlands occur along the
margins of the alkali wetlands in addition to salt grass, silverscale saltbush (Atriplex argentea),
and spikeweed (Centromadia ssp.).
Streams
Intermittent Drainages
Several drainages cross the project site. These drainages appear to be intermittent in nature,
carrying water only during the wet season. The banks of the drainages are generally dominated by
non-native grasses similar to those described in annual grassland, above. The top of banks are
dominated by black mustard and Italian thistle (Carduus pycnocephalus).
Brushy Creek travels through the project site from the southwest and exits on the northern end at
Armstrong Road. The creek holds more water than the other drainages; however, it is considered
intermittent because it maintains flows only when rainwater provides adequate surface and subsurface
flow. An unnamed tributary to Brushy Creek flows through the eastern portion of the project site,
draining rainwater runoff from the hills south of the project site north to eventually meet with Brushy
Creek northeast of the project site. These features maintain flow only when there is adequate water in
the system from rainfall or groundwater and are typically dry during dry periods.
3.3.1.3 Special-Status Species
A total of 33 species of vascular plants were recorded during site surveys (see Appendix D). Of these
33 species, 13 are native to California. The remainders are non-native species which have become
adapted to annual grasslands in California. It should be noted that the first site survey was conducted
very early in the growing season, at a time when most plants are not evident and identifiable, and the
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-5
second survey was performed in winter; as such, floristic surveys conducted at the appropriate time of
the growing season would likely yield a greater number of identifiable species.
During the field surveys, 17 wildlife species or signs of such were observed: red-winged blackbird
(Agelaius phoeniceus), tricolored blackbird (Agelaius tricolor), western meadowlark (Sturnella

For the purposes of this Environmental Impact Report (EIR), special-status wildlife species are
those listed as threatened or endangered under the federal Endangered Species Act (FESA) or
California Endangered Species Act (CESA), listed as Fully Protected or a Species of Special
Concern by the California Department of Fish and Wildlife (CDFW), or listed by the California
Native Plant Society as rare, threatened, or endangered (California Rare Plant Ranks 1B.1 and
1B.2). A search of the California Natural Diversity Database (CDFW 2019), the IPaC report
(USFWS 2016), and the California Native Plant Society Inventory of Rare and Endangered Plants
(CNPS 2018) was conducted for the Byron Hot Springs U.S. Geological Survey 7.5-minute
quadrangle and the surrounding eight quadrangles in 2016 and again in 2018 to determine special-
status species within the project area (Appendix D).
Special-Status Wildlife
Results of the California Natural Diversity Database and U.S. Fish and Wildlife Service (USFWS)
searches revealed 25 listed or special-status wildlife species, or species proposed for listing as rare,
threatened, or endangered by either the CDFW or the USFWS. Of these, 14 were removed from
consideration due to lack of suitable habitat within or adja cent to the project site, or due to the
project site being outside of the species’ known range. Of the 11 remaining species, three were
observed during the field visit. These were loggerhead shrike, golden eagle, and tricolored
blackbird. Suitable nesting and foraging habitat exists for these species on or adjacent to the site.
The eight remaining species have a moderate to high potential to occur on the site due to the
availability of suitable habitat on the site or due to the site occurring within the species’ known
range. These include California red-legged frog (Rana draytonii), California tiger salamander
(Ambystoma californiense), longhorn fairy shrimp (Branchinecta longiantenna), vernal pool fairy
shrimp (Branchinecta lynchi), conservancy fairy shrimp (Branchinecta conservatio), vernal pool
tadpole shrimp (Lepidurus packardi), Swainson’s hawk, and burrowing owl (Athene cunicularia).

All raptor species found in California are protected by California Fish and Game Code Section
3503.5 and may use the study area for nesting or foraging. Several raptors were observed on or
flying over the project site during the surveys. Although raptor species have the potential to nest
and forage on the project site and adjacent to the site, the study area does not provide substantially
important habitat, due to its small size, that would affect raptor species from continuing to exist
within the area.
Special-Status Plants
Results of the California Natural Diversity Database and California Native Plant Society searches
revealed 44 special-status plant species that have potential to occur in the vicinity of the project
site. Of these, 27 were removed from consideration due to lack of suitable habitat within the project
site, or due to the project site being outside of the species’ known range (refer to Appendix D).
Eight special-status plant species have low potential to occur at the project site due to lack of
appropriate soil substrates or have no documented occurrences in the vicinity. Nine special-status
plant species have moderate to high potential to occur at the project site. These include alkali milk-
vetch (Astragalus tener var. tener), brittlescale (Atriplex depressa), big tarplant (Blepharizonia
plumosa), round-leaved filaree (California macrophylla), Congdon’s tarplant (Centromadia parryi
ssp. congdonii), recurved larkspur (Delphinium recurvatum), spiny-sepaled button-celery
(Eryngium spinosepalum), diamond-petaled California poppy (Eschscholzia rhombipetala), and
Contra Costa goldfields (Lasthenia conjugens).
Spiny-sepaled button-celery, recurved larkspur, brittlescale, and alkali milk-vetch have been
previously documented at the Byron Airport Habitat Management Lands within the project site.
There is a high level of continuity between the wetlands where these species have been previously
documented and the wetlands present on the site; thus, there is a high likelihood these special-
status plant species occur within suitable habitat on the project site. No special-status plants were
observed during the field survey; however, the site survey was conducted at a time when special -
status plants would not be evident and identifiable.
3.3.1.4 Sensitive Resources and/or Habitats
Five sensitive resources or habitats occur within the study area, including vernal pools, seasonal
wetlands, alkali wetlands, alkali grassland, and drainages, all of which are described above in
Section 3.3.1.2. The study area is located directly adjacent to the Byron Airport Habitat
Management Lands, which are an approximately 814-acre conservation easement. Numerous
sensitive resources have been documented within the Byron Airport Habitat Management Lands.

3.3.1.5 Wildlife Corridors and Habitat Linkages
Wildlife corridors are landscape features, usually linear in shape, that facilitate movement of animals
(or plants) over time between two or more patches of otherwise disjunct habitat. Corridors can be
small and even human-made (e.g., highway underpasses, culverts, bridges), narrow linear habitat
areas (e.g., riparian strips, hedgerows), or wider landscape-level extensions of habitat that ultimately
connect even larger core habitat areas. Depending on the size and extent, wildlife corridors can be
used during animal migration, foraging events, and juvenile dispersal, and ultimately serve to
facilitate genetic exchange between core populations, provide avenues for plant seed dispersal,
enable increased biodiversity and maintenance of ecosystem integrity within habitat patches, and
help offset the negative impacts of habitat fragmentation. Although the site is a non-linear feature, it
has value as a potential wildlife corridor or habitat linkage between areas of open grassland and
agricultural habitat. Brushy Creek flows from the uplands southwest of the site, through the site, and
eventually drains to the San Joaquin River Delta to the northeast of project site, providing important
aquatic linkages between upland and aquatic habitat. Habitat management lands on the project site
have interconnected vernal pool and wetland complexes that extend onto the study area.
3.3.1.6 Aquatic Habitats and Jurisdictional Wetlands and Waters
The project site is located in the Lower Sacramento River watershed, within the San Joaquin Delta
hydrologic unit (Hydrologic Unit Code 1804003). Aquatic features within the site include
numerous seasonal wetlands, alkali wetlands, swales, and drainages that are scattered throughout
the site. Brushy Creek passes through the site from the southwest and exits the site at the northern
extent where it eventually flows into Italian Slough which in turn flows into Old River and the San
Joaquin River Delta to the northeast of the project site. Most of these features occur in the northern
and western portions of the site (Figure 3.3-1). Based on historic aerial photography and visual
inspection during the site surveys, these features are only periodically inundated and tend to remain
inundated for short periods, depending on the amount of rainfall in a given year.
A current wetland delineation has not been completed for the site. However, based on the site
assessments, several potentially jurisdictional areas were identified and are discussed above. These
features are most likely considered waters of the United States and the State of California, and
would therefore require permits from the CDFW, U.S. Army Corps of Engineers (ACOE), and
Regional Water Quality Control Board (RWQCB) if impacts to these features from development
of the property are unavoidable.

3.3.2 Relevant Plans, Policies, and Ordinances
Federal
Federal Endangered Species Act
The FESA prohibits the taking, possession, sale, or transport of endangered species. Pursuant to
the requirements of FESA, a federal agency reviewing a project within its jurisdiction must
determine whether any federally listed threatened or endangered species could be present in the
project site and determine whether the project would have a potentially significant impact on such
species. In addition, federal agencies are required to determine whether the project is likely to
jeopardize the continued existence of any species proposed to be listed under FESA or result in
the destruction or adverse modification of critical habitat proposed to be designated for such
species (16 USC 1536[3], 1536[4]). Projects that would result in “take” of any federally listed
threatened or endangered species are required to obtain authorization from the National Marine
Fisheries Service and/or USFWS through either Section 7 (interagency consultation) or Section
10(a) (incidental take permit) of FESA, depending on whether the federal government is involved
in permitting or funding the project.
Migratory Bird Treaty Act
The Migratory Bird Treaty Act (MBTA) regulates or prohibits taking, killing, possession of, or
harm to migratory bird species listed in Title 50 of the Code of Federal Regulations, Section 10.13.
The MBTA is an international treaty for the conservation and management of bird species that
migrate through more than one country, and is enforced in the United States by the USFWS.
Hunting of specific migratory game birds is permitted under the regulations listed in Title 50 of
the Code of Federal Regulations, Section 20. The MBTA was amended in 1972 to include
protection for migratory birds of prey (raptors).
Federal Clean Water Act (Section 404)
The objective of the federal Clean Water Act (CWA) is to restore and maintain the chemical,
physical, and biological integrity of the nation's waters. Under Section 404 of the CWA, the ACOE
has the authority to regulate activity that could discharge fill or dredge material or otherwise
adversely modify wetlands or other waters of the United States. The ACOE implements the federal
policy embodied in Executive Order 11990, which, when implemented, is intended to result in no
net loss of wetland values or function.
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-9
Federal Clean Water Act (Section 401)
The State Water Resources Control Board (SWRCB) has authority over wetlands through Section
401 of the CWA, the Porter-Cologne Act, California Code of Regulations Section 3831(k), and
California Wetlands Conservation Policy. The CWA requires that an applicant for a Section 404
permit (to discharge dredged or fill material into waters of the United States) first obtain a
certificate from the appropriate state agency stating that the fill is consistent with the state’s water
quality standards and criteria. In California, the authority to either grant certification or waive the
requirement for permits is delegated by the SWRCB to the nine regional boards. The Central
Valley RWQCB is the appointed authority for Section 401 compliance in the project area. A
request for certification or waiver is submitted to the regional board at the same time that an
application is filed with the ACOE.
State
California Endangered Species Act
Under the CESA, the California Fish and Game Commission has the responsibility of maintaining
a list of threatened species and endangered species. The CDFW also maintains lists of species of
special concern. A Species of Special Concern is a species, subspecies, or distinct population of
an animal native to California that currently satisfies one or more of the following (not necessarily
mutually exclusive) criteria:
• is extirpated (extinct) from the state or, in the case of birds, is in its primary seasonal or
breeding role;
• is federally listed, but not state-listed, as threatened or endangered;
• meets the state definition of threatened or endangered but has not formally been listed;
• is experiencing, or formerly experienced, serious (noncyclical) population declines or
range retractions (not reversed) that, if continued or resumed, could qualify it for state
threatened or endangered status; or
• has naturally small populations exhibiting high susceptibility to risk from any factor(s),
that if realized, could lead to declines that would qualify it for state threatened or
endangered status.
CESA prohibits the take of California-listed animals and plants in most cases, but CDFW may
issue incidental take permits under special conditions. Pursuant to the requirements of CESA, a
state agency reviewing a project within its jurisdiction must determine whether any state-listed
endangered or threatened species could be present in the project site and determine whether the
project would have a potentially significant impact on such species.
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-10
California Fish and Game Code Sections 3503, 3511, 3513
California Fish and Game Code Section 3503 states that it is unlawful to take, possess, or
needlessly destroy the nests or eggs of any bird, except as otherwise provided by this code or any
regulation made pursuant thereto. California Fish and Game Code Section 3503.5 protects all birds
of prey (raptors) and their eggs and nests. Section 3511 states fully protected birds or parts thereof
may not be taken or possessed at any time. Section 3513 states that it is unlawful to take or possess
any migratory non-game bird as designated in the MBTA.
Streambed Alteration Agreement
Under Sections 1600-1616 of the California Fish and Game Code, the CDFW regulates activities
that would alter the flow, bed, channel, or bank of streams and lakes. The limits of CDFW’s
jurisdiction are defined in the code as the “bed, channel or bank of any river, stream, or lake
designated by the department in which there is at any time an existing fish or wildlife resource or
from which these resources derive benefit” (California Fish and Game Code Section 1601). In
practice, the CDFW usually marks its jurisdictional limit at the top of the stream or bank, or at the
outer edge of the riparian vegetation, whichever is wider.
Wetlands Protection Regulations
CDFW derives its authority to oversee activities that affect wetlands from state legislation. This
authority includes Sections 1600–1616 of the California Fish and Game Code (lake and streambed
alteration agreements), CESA (protection of state-listed species and their habitats, which could
include wetlands), and the Keene-Nejedly California Wetlands Preservation Act of 1976 (states a
need for an affirmative and sustained public policy program directed at wetlands preservation,
restoration, and enhancement). In general, the CDFW asserts authority over wetlands within the
state either through review and comment on ACOE Section 404 permits, review and comment on
California Environmental Quality Act (CEQA) documents, preservation of state-listed species, or
through stream and lakebed alteration agreements.
Porter-Cologne Water Quality Control Act
The Porter-Cologne Water Quality Control Act established the SWRCB and each RWQCB as the
principal state agencies for coordinating and controlling water quality in California. Responsibility
for the protection of water quality in California rests with the SWRCB and nine RWQCBs. The
Central Valley RWQCB has regulatory authority over the project area.
The Porter-Cologne Water Quality Control Act provides that “all discharges of waste into the
waters of the State are privileges, not rights.” Waters of the state are defined in Section 13050(e)
of the Porter-Cologne Water Quality Control Act as “any surface water or groundwater, including
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-11
saline waters, within the boundaries of the state.” All dischargers are subject to regulation under
the Porter-Cologne Water Quality Control Act, including both point and nonpoint source
dischargers. The Central Valley RWQCB has authority to implement water quality protection
standards through issuance of permits for discharges to waters at locations within its juris diction,
which would include the project site. As noted above, the Central Valley RWQCB is the appointed
authority for Section 401 compliance in the project area. If the ACOE determines that they have
no regulatory authority in the project area and also that a CWA Section 404 permit is not required,
the project proponent could still be responsible for obtaining the appropriate CWA Section 401
permit or waiver from Central Valley RWQCB for impacts to waters of the state.
California Environmental Quality Act
Although threatened and endangered species are protected by specific federal and state statutes,
CEQA Guidelines Section 15380(b) provides that a species not listed on the federal or state list of
protected species may be considered rare or endangered if the species can be shown to meet certain
criteria. These criteria have been modeled after the definition in FESA and the section of the
California Fish and Game Code dealing with rare or endangered plants and animals, and allows a
public agency to undertake a review to determine if a significant effect on a species that has not
yet been listed by either the USFWS or CDFW (i.e., species of concern) would occur. Whether a
species is rare, threatened, or endangered can be legally significant because, under CEQA
Guidelines Section 15065, an agency must find an impact to be significant if a project would
“substantially reduce the number or restrict the range of an endangered, rare, or threatened
species.” Thus, CEQA provides an agency with the ability to protect a species from a project’s
potential impacts until the respective government agencies have an opportunity to designate the
species as protected, if warranted.

Contra Costa County General Plan
The 2005–2020 Contra Costa County General Plan was adopted in 2005. The General Plan Land
Use Element Map (Contra Costa County 2005b) designates the project site as a combination of
Public-Semi-Public and Open Space (indicating the habitat management lands). The private

require a biotic resources evaluation based upon field reconnaissance performed at the
appropriate time of year to determine the presence or absence of rare, threatened or
endangered species of plants or animals. Such evaluation will consider the potential for
significant impact on these resources, and measures proposed to mitigate such impacts,
where feasible, or indicate why mitigation if not feasible.
Measure 8-g Require the environmental impact analysis of all significant grassland land sites
proposed for development to include an early spring site reconnaissance to
determine the presence of vernal pools and rare species associated with vernal
pools, and document the use of any seasonal wetlands by water bird species. A

insufficient for environmental review. Significant grasslands include generally
parcels of more than 40 acres which are located in an area dominated by native or
introduced grass species.
Measure 8-j A setback from the edge of any wetland area may be required for any new structure.
The breadth of any such setback shall be determined by the County after
environmental review examining (a) the size and habitat value of the potentially
affected wetland, and (b) potential impacts on the wetland, and adjacent uplands,
arising out of the development and operation of the new structure. Unless
environmental review indicates that greater or lesser protection is necessary or
adequate, setbacks generally will be between 50 and 100 feet in breadth.
Expansions or other modifications of non-habitable agriculturally-related structures
existing as of 1990 shall be exempt from this setback requirement. Parcels which
would be rendered un-buildable by application of this standard shall also be exempt.
Measure 8-l The County shall require avoidance, minimization and/or compensatory mitigation
techniques to be employed with respect to specific development projects having a
potential to affect a wetland. In evaluating the level of compensation to be required
with respect to any given project, (a) on-site mitigation shall be preferred to off site
and in-kind mitigation shall be preferred to out-of-kind, (b) functional replacement
ratios may vary to the extent necessary to incorporate a margin of safety reflecting
the expected degree of success associated with the mitigation plan, and (c) acreage
replacement ratios may vary depending on the relative functions and values of those
wetlands being lost and those being supplied. To the extent permitted by law, the
County may require 3:1 compensatory mitigation of any project affecting a
“Significant Wetland.”

Contra Costa County Tree Protection and Preservation Ordinance
Division 816 of the Contra Costa County Ordinance Code defines protected trees and outlines
measures that must be implemented if these trees are to be adversely affected or removed. The
ordinance requires site plans for development projects to accurately depict the location, species,
tree dripline, and trunk circumference of all trees with a trunk circumference of 20 inches (50
centimeters) or more, measured 4.5 feet (1.37 meters) above the ground, whose tree trunks lie
within 50 feet (15.2 meters) of proposed grading or other proposed improvements or other
proposed development activity (e.g., stockpiling of construction materials, fill). The ordinance also
requires the site plan to clearly indicate whether individual trees are proposed to be removed,
altered, or otherwise affected. Trees proposed for preservation on a site are to be fenced during
construction activities. The Tree Protection Ordinance requires a tree permit for removal of 6.5-
inch-diameter at breast height trees in or adjacent to riparian, foothill woodland, or oak savanna
areas, or that are part of a stand of four or more trees (protected trees). Furthermore, the ordinance
requires a tree permit to trench, grade, or fill within the dripline of protected trees. Accidental
destruction requires adequate restitution.
East Contra Costa County Habitat Conservation Plan/Natural Community Conservation Plan
The East Contra Costa County Habitat Conservation Plan (HCP)/Natural Community
Conservation Plan (NCCP) was adopted in August 2007. The HCP/NCCP offers a framework for
regional conservation and development, providing for the protection of natural resources while
streamlining the permitting process for take of federally and state-listed species and for mitigating
impacts on sensitive habitats and resources. The County is a co-permittee of the HCP/NCCP,
which is overseen by the East Contra Costa County Habitat Conservancy. The HCP/NCCP
provides 30-year species permits for urban development and rural infrastructure projects in eastern
Contra Costa County. Impacts from these projects are offset by contributions to a Preserve System
that will be managed for the benefit of 28 covered species and their habitats (ECCCHCPA 2006).
The land surrounding the project site is in the HCP/NCCP’s Acquisition Analysis Zone 5
(ECCCHCPA 2006). These lands provide conservation benefits, and acquisition of these lands for
the Preserve System would achieve the biological goals and objectives of the HCP/NCCP.
The approximately 300-acre development of Byron Airport is a covered activity under the
HCP/NCCP. Permits issued in 1992 and 1993 by the USFWS and the CDFW, respectively,
authorized take of San Joaquin kit fox (Vulpes macrotis mutica) resulting from construction of the
Byron Airport (ECCCHCPA 2006). These permits covered approximately 200 acres of impacts to
natural land cover types. Approximately 112 acres of land were developed at that time and
approximately 88 acres of take coverage for San Joaquin kit fox remains for the airport under these
earlier permits. Chapter 5 of the HCP/NCCP notes that future development at Byron Airport may
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269

be mitigated through the implementation of an avoidance and preservation program in and around
the airport property (rather than the County paying the mitigation fees) due to the habitat values of
lands at Byron Airport (ECCCHCPA 2006). These lands are an important part of the connectivity
of the HCP/NCCP Preserve System, and provide an important connection between habitat in
Contra Costa County and Alameda County.
3.3.3 Thresholds of Significance
The significance criteria used to evaluate the project impacts to biological resources are based on
Appendix G of the CEQA Guidelines. According to Appendix G, a significant impact related to
biological resources would occur if the project would:
1. Have a substantial adverse effect, either directly or through habitat modifications, on any
species identified as a candidate, sensitive, or special status species in local or regional
plans, policies, or regulations, or by the California Department of Fish and Wildlife
[formerly California Department of Fish and Game] or U.S. Fish and Wildlife Service.
2. Have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies, regulations or by the California
Department of Fish and Wildlife or U.S. Fish and Wildlife Service.
3. 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.
4. 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 native wildlife nursery sites.
5. Conflict with any local policies or ordinances protecting biological resources, such as a
tree preservation policy or ordinance.
6. Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community
Conservation Plan, or other approved local, regional, or state habitat conservation plan.
3.3.4 Impacts Analysis
Impact 3.3-1. The project may have a substantial adverse effect, either directly or through
habitat modifications, on species identified as a candidate, sensitive, or special
status species in local or regional plans, policies, or regulations, or by the
California Department of Fish and Wildlife or U.S. Fish and Wildlife Service.

Impacts to Special-Status Wildlife from Construction
Three special-status wildlife species were detected during the surveys conducted for the project
site, as discussed in Section 3.3.1.3. These species include loggerhead shrike, golden eagle, and
tricolored blackbird. Several other special-status species have the potential to utilize the project
site for nesting, foraging, cover and/or local migration routes. Although the study area has few
mature trees, the project site and adjacent lands have potential nesting habitat for Swainson’s hawk
and several common raptor species found in California, such as northern harrier and red -tailed
hawk (Buteo jamaicensis), and also common passerine species such as western meadowlark.
Annual grassland within the study area provides suitable nesting habitat for Burrowing owl.
While no suitable nesting trees were identified in the proposed development areas, project
construction could affect nesting raptors up to 1,000 feet away from project activities. Mature
eucalyptus trees along the eastern border of the project site provide suitable nesting habitat for
raptors and are within direct line of sight of the proposed project activities. Increased noise, light,
and vibration associated with construction activities could negatively affect nesting success if such
activities occur during the nesting season (generally March 15 through September 15, depending
on species). This is a potentially significant impact. Mitigation Measure (MM) BIO-1 requires
that a nesting bird survey be conducted and nests be avoided during construction.
Additionally, six remaining special-status wildlife species have a moderate to high potential to
occur on site due to the availability of suitable habitat or because the site is located within the
species’ known range. These include California red-legged frog, California tiger salamander,
longhorn fairy shrimp, vernal pool fairy shrimp, conservancy fairy shrimp, and vernal pool tadpole
shrimp. While seasonal wetland habitat suitable for longhorn fairy shrimp, venal pool fairy shrimp,
conservancy fairy shrimp, and vernal pool tadpole shrimp is located outside the proposed aviation
and non-aviation Areas, there is potential for indirect impacts to suitable habitat through sediment
and water runoff into wetlands. This is a potentially significant impact.
Ground-disturbing activities in grassland habitat has potential to cause direct impacts to suitable
nesting and upland refuge habitat for burrowing owl, California red-legged frog, and California
tiger salamander. This is a potentially significant impact. MM-BIO-2, MM-BIO-3, and MM-
BIO-4 would require focused surveys to be conducted prior to project construction for burrowing
owl, California red-legged frog, and California tiger salamander, respectively. Avoidance
measures would be implemented if these species are detected.
Impacts to Special-Status Wildlife from Operation
While the proposed build-out of the project would result in removal of habitat for resident and
migratory wildlife, proposed operational activities would be consistent with current aviation
activities at the Byron Airport. Potential commercial and industrial activities would occur on the
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-19
eastern edge of the project site, near Runway 12/30 and existing agricultural and residential uses.
There would be no significant increase in effects on wildlife on surrounding lands, including lands
managed for habitat. Following any disruptions caused by construction, project operations would
not further affect the amphibian species discussed above, while special status bird species may
continue to utilize the majority of the project site for nesting, foraging, cover and/or local migration
routes. Thus, impacts associated with the operation of the airport on special-status wildlife would
be less than significant.
Impacts to Special-Status Plant Species from Construction
No special-status plant species were observed on the project site during the surveys; however, the
site surveys was conducted when the plants were not evident or identifiable. Because there is
suitable habitat for special-status plant species at the project site, and four special-status plant
species have been previously documented on the adjacent Byron Airport Habitat Management
Lands, there is potential for these species to be present. These include alkali milk-vetch,
brittlescale, big tarplant, round-leaved filaree, Congdon’s tarplant, recurved larkspur, spiny-
sepaled button-celery, diamond-petaled poppy, and Contra Costa goldfields. Grading activity and
heavy machinery could potentially trample, damage, and/or remove special-status plant species
and their associated seed banks. Destruction of aquatic habitat such as wetlands and vernal pools
that support special-status plant species would also remove seed banks and individual plants, and
altered hydrology due to project activities could affect the health of plants in the future. Thus,
project-related impacts on special status plant populations would be potentially significant.
Impacts to Special-Status Plant Species from Operations
Operational activities associated with the build-out of the proposed project would be consistent
with current activities at Byron Airport and would include maintenance of grassland habitat in
airport-related areas through mowing. Operation of the proposed project is anticipated to result in
no impact to special-status plant species.
Impact 3.3-2. The project would have a substantial adverse effect on riparian habitat or
other sensitive natural community identified in local or regional plans,
policies, regulations or by the California Department of Fish and Wildlife or
U.S. Fish and Wildlife Service. (Potentially Significant)
Potential impacts from the project would occur to all land cover types present on site. Most areas
directly adjacent to the existing airport and to the north and east of the existing runways consist of
non-native annual grassland. While grasslands are not a sensitive natural community, the
HCP/NCCP considers certain types of grassland, such as alkali grassland, to be sensitive. As
described further in Impact 3.3-6, below, expansion of Byron Airport is a covered activity. As
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-20
such, participation in the HCP/NCCP would provide for the mitigation of grassland conversion
(MM-BIO-10).
Sensitive vegetation communities, including wetlands and alkali grasslands, occur within the
project site and, under the HCP/NCCP, would require either avoidance or other mitigation.
Sensitive resources and habitats include vernal pools, seasonal wetlands, alkali wetlands, and
drainages, all of which are potentially jurisdictional features regulated by CDFW, USFWS, and
ACOE. Construction of the proposed project could result in direct habitat destruction or
modification, which is a potentially significant impact. MM-BIO-6 requires that a wetlands
delineation is performed and avoidance buffers around potentially jurisdictional resources are
established prior to construction, and also implements a setback from Brushy Creek. MM-BIO-7
requires that alkali grassland on site is avoided to the extent feasible. Implementation of MM-BIO-
6, and MM-BIO-7, and MM-BIO-10 would reduce impacts to sensitive natural communities to a
less-than-significant level.
Impact 3.3-3. The project would 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.
(Potentially Significant)
Although a current wetland delineation has not been completed for the project site, the Biological
Constraints Report completed for the project indicates that all of the seasonal wetlands, swales,
drainages, and vernal pools on the site are most likely under the joint regulation of the ACOE,
RWQCB, and CDFW (Appendix D). In consideration of this, MM-BIO-6 requires a detailed
jurisdictional delineation to be performed by a qualified biologist or wetland scientist prior to
project development activities. If jurisdictional features would be impacted by the project,
authorization from the resource agencies listed above would be required in the form of wetland
permits (e.g., 404 Nationwide Permit, 401 Water Quality Certification, and 1602 Streambed
Alteration Agreement respectively). Required compensatory mitigation would provide no net loss
of jurisdictional habitats. With implementation of MM-BIO-6 and necessary permitting, impacts
to protected wetlands would be reduced to a less-than-significant level.
Impact 3.3-4. The project would not interfere substantially with the movement of any native
resident or migratory fish or wildlife species or with established native
resident or migratory wildlife corridors, or impede the use of native wildlife
nursery sites. (Less than Significant)
As described previously in Section 3.3.1.5, Brushy Creek provides a corridor from the uplands
southwest of the project site to Italian Slough, Old River, and the greater San Joaquin River Delta
to the northeast of the site. Adjacent conservation lands have interconnected vernal pool and
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-21
wetland complexes that extend onto the site. Additionally, the project site offers a habitat linkage
between areas of open grassland and agricultural habitat. The mitigation lands on airport property
are included in the HCP/NCCP to provide a corridor between habitat in Alameda and Contra Costa
counties. The development areas on the airport were considered in the development of the
acquisition areas, including on-airport mitigation lands. Therefore, development of the airport
consistent with the Byron Airport Master Plan and the HCP/NCCP would not substantially
interfere with a wildlife corridor. The impact would be less than significant.
Impact 3.3-5. The project would not conflict with any local policies or ordinances protecting
biological resources, such as a tree preservation policy or ordinance. (Less
than Significant)
As discussed in Section 3.3.2, the County maintains ordinances, policies, and codes protecting
sensitive species, habitats, and trees. The proposed project is not likely to affect trees protected by
County policy. Scattered trees are present on the 11.7-acre acquisition parcel, but their potential
removal would occur after acquisition by the County and would not require a permit under the
County tree protection and preservation ordinance. Impacts to special-status species, wetlands, and
vegetation communities would be avoided or mitigated as described in MM-BIO-1 through MM-
BIO-9. Thus, the project would comply with County General Plan goals and policies to analyze
and protect biological resources. The project would not conflict with any local policies or
ordinances protecting biological resources, and impacts would be less than significant.
Impact 3.3-6. The project would not conflict with the provisions of an adopted Habitat
Conservation Plan, Natural Community Conservation Plan, or other approved
local, regional, or state habitat conservation plan. (Less than Significant)
The project site is within the area covered by the HCP/NCCP. The majority of the County-owned
property at Byron Airport, approximately 934 acres, is managed by the County Airports Division
as habitat. The conservation easements for the airport predate the HCP/NCCP, but are generally
consistent with the HCP/NCCP’s guiding principles. The project would not affect the adjacent
lands preserved under the conservation easement.
Additional build-out and development of Byron Airport is identified as a covered activity in the
HCP/NCCP. Permits issued in 1992 and 1993 by the USFWS and the CDFW, respectively,
authorized take of San Joaquin kit fox resulting from construction of the Byron Airport
(ECCCHCPA 2006). These permits covered approximately 200 acres of impacts to natural land
cover types. Approximately 112 acres of land was developed at that time and approximately 88 acres
of take coverage for San Joaquin kit fox remains for the airport under these earlier permits. The
HCP/NCCP details that development above 66 acres of the aforementioned 88 acres would be
mitigated at a level of 2.4 acres per acre developed. The HCP/NCCP details the implementation of
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-22
an avoidance and preservation program and identifies the land that would be impacted, avoided, and
preserved in perpetuity. In addition to conservation of land occurring within airport property, the
avoidance and preservation program requires conservation of land off-site as well. In addition, the
proposed construction and operational activities analyzed in this EIR would comply with the
conditions of the HCP/NCCP. Therefore, the potential for conflict with an approved HCP/NCCP is
less than significant.
3.3.5 Mitigation Measures
Coverage under the HCP/NCCP is the primary mechanism for mitigating impacts to species and
habitats covered by the HCP/NCCP. MM-BIO-1a, MM-BIO-2, MM-BIO-3, MM-BIO-4, MM-
BIO-5, MM-BIO-8, and MM-BIO-9 conform to the avoidance and minimization measures in the
HCP/NCCP. Other project-specific mitigation measures have been developed consistent with state
and federal regulations and standards.
MM-BIO-1
a. Swainson’s Hawk Pre-Construction Survey, Avoidance, Minimization, and
Construction Monitoring. Prior to any ground disturbance related to covered
activities that occurs during the nesting season (March 15–September 15), a
qualified biologist will conduct a preconstruction survey no more than 1 month
prior to construction to establish whether Swainson’s hawk nests within 1,000 feet
of the project site are occupied. If potentially occupied nests within 1,000 feet are
off the project site, then their occupancy will be determined by observation from
public roads or by observations of Swainson’s hawk activity (e.g., foraging) near
the project site. If nests are occupied, minimization measures and construction
monitoring are required (see below).
During the nesting season (March 15–September 15), covered activities within
1,000 feet of occupied nests or nests under construction will be prohibited to
prevent nest abandonment. If site-specific conditions or the nature of the covered
activity (e.g., steep topography, dense vegetation, limited activities) indicate that a
smaller buffer could be used, the East Contra Costa County Habitat Conservancy
will coordinate with the California Department of Fish and Wildlife (CDFW)/U.S.
Fish and Wildlife Service (USFWS) to determine the appropriate buffer size.
If young fledge prior to September 15, covered activities can proceed normally. If
the active nest site is shielded from view and noise from the project site by other
development, topography, or other features, the project proponent can apply to the
East Contra Costa County Habitat Conservancy for a waiver of this avoidance
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-23
measure. Any waiver must also be approved by USFWS and CDFW. While the
nest is occupied, activities outside the buffer can take place.
All active nest trees will be preserved on site, if feasible. Nest trees, including non-
native trees, lost to covered activities will be mitigated by the project proponent
according to the requirements below.
Mitigation for Loss of Nest Trees
The loss of non-riparian Swainson’s hawk nest trees will be mitigated by the project
proponent by:
• If feasible on-site, planting 15 saplings for every tree lost with the objective
of having at least 5 mature trees established for every tree lost according to
the requirements listed below.
AND either
1. Pay the Implementing Entity an additional fee to purchase, plant,
maintain, and monitor 15 saplings on the HCP/NCCP Preserve System
for every tree lost according to the requirements listed below, OR
2. The project proponent will plant, maintain, and monitor 15 saplings for
every tree lost at a site to be approved by the Implementing Entity (e.g.,
within an HCP/NCCP Preserve or existing open space linked to
HCP/NCCP preserves), according to the requirements listed below.
The following requirements will be met for all planting options:
• Tree survival shall be monitored at least annually for 5 years, then every
other year until year 12. All trees lost during the first 5 years will be
replaced. Success will be reached at the end of 12 years if at least 5 trees
per tree lost survive without supplemental irrigation or protection from
herbivory. Trees must also survive for at least three years without irrigation.
• Irrigation and fencing to protect from deer and other herbivores may be
needed for the first several years to ensure maximum tree survival.
• Native trees suitable for this site should be planted. When site conditions
permit, a variety of native trees will be planted for each tree lost to provide
trees with different growth rates, maturation, and life span, and to provide a
variety of tree canopy structures for Swainson’s hawk. This variety will help
to ensure that nest trees will be available in the short term (5-10 years for
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-24
cottonwoods and willows) and in the long term (e.g., Valley oak, sycamore).
This will also minimize the temporal loss of nest trees.
• Riparian woodland restoration conducted as a result of covered activities
(i.e., loss of riparian woodland) can be used to offset the nest tree planting
requirement above, if the nest trees are riparian species.
• Whenever feasible and when site conditions permit, trees should be planted
in clumps together or with existing trees to provide larger areas of suitable
nesting habitat and to create a natural buffer between nest trees and adjacent
development (if plantings occur on the development site).
• Whenever feasible, plantings on the site should occur closest to suitable
foraging habitat outside the UDA.
• Trees planted in the HCP/NCCP preserves or other approved offsite
location will occur within the known range of Swainson’s hawk in the
inventory area and as close as possible to high-quality foraging habitat.
b. Migratory Bird Treaty Act Nesting Bird Avoidance. As part of the pre-construction
survey for Swainson’s hawk, the qualified biologist approved by USFWS/CDFW
shall also survey for native nesting birds protected by the Migratory Bird Treaty
Act. If any active nests are observed during surveys, a suitable avoidance buffer
from the nests shall be determined and flagged by the qualified biologist based on
species, location, and planned construction activity. Consultation with CDFW may
be required to determine appropriate buffer distances. These nests shall be avoided
until the chicks have fledged and the nests are no longer active, as determined by
the qualified biologist. Habitat (i.e., trees and brush) may not be removed during
the breeding bird season.
MM-BIO-2 Western Burrowing Owl Pre-Construction Survey, Avoidance, Minimization,
and Construction Monitoring. In accordance with Conditions on Covered
Activities described in the East Contra Costa County HCP/NCCP, prior to any
ground disturbance related to covered activities, a U.S. Fish and Wildlife Service
(USFWS)/California Department of Fish and Wildlife (CDFW)-approved biologist
shall conduct a preconstruction survey in areas identified as having potential
burrowing owl habitat. The surveys will establish the presence or absence of
western burrowing owl and/or habitat features and evaluate use by owls in
accordance with CDFW survey guidelines (CDFG 1995).
On the parcel where the activity is proposed, the biologist will survey the proposed
disturbance footprint and a 500-foot radius from the perimeter of the proposed
footprint to identify burrows and owls. Adjacent parcels under different land
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-25
ownership will not be surveyed. Surveys should take place near sunrise or sunset
in accordance with CDFW guidelines. All burrows or burrowing owls will be
identified and mapped. Surveys will take place no more than 30 days prior to
construction. During the breeding season (February 1–August 31), surveys will
document whether burrowing owls are nesting in or directly adjacent to disturbance
areas. During the nonbreeding season (September 1–January 31), surveys will
document whether burrowing owls are using habitat in or directly adjacent to any
disturbance area. Survey results will be valid only for the season (breeding or
nonbreeding) during which the survey is conducted.
This measure incorporates avoidance and minimization guidelines from CDFW’s
Staff Report on Burrowing Owl Mitigation (California Department of Fish and
Game 1995).
If burrowing owls are found during the breeding season (February 1–August 31),
the project proponent will avoid all nest sites that could be disturbed by project
construction during the remainder of the breeding season or while the nest is
occupied by adults or young. Avoidance will include establishment of a non-
disturbance buffer zone (described below). Construction may occur during the
breeding season if a qualified biologist monitors the nest and determines that the
birds have not begun egg-laying and incubation or that the juveniles from the
occupied burrows have fledged. During the nonbreeding season (September 1–
January 31), the project proponent should avoid the owls and the burrows they are
using, if possible. Avoidance will include the establishment of a buffer zone
(described below).
During the breeding season, buffer zones of at least 250 feet in which no
construction activities can occur will be established around each occupied burrow
(nest site). Buffer zones of 160 feet will be established around each burrow being
used during the nonbreeding season. The buffers will be delineated by highly
visible, temporary construction fencing.
If occupied burrows for burrowing owls are not avoided, passive relocation will be
implemented. Owls should be excluded from burrows in the immediate impact zone
and within a 160-foot buffer zone by installing one-way doors in burrow entrances.
These doors should be in place for 48 hours prior to excavation. The project area
should be monitored daily for 1 week to confirm that the owl has abandoned the
burrow. Whenever possible, burrows should be excavated using hand tools and
refilled to prevent reoccupation (CDFG 1995). Plastic tubing or a similar structure
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-26
should be inserted in the tunnels during excavation to maintain an escape route for
any owls inside the burrow.
MM-BIO-3 California Red-Legged Frog Minimization. Written notification to U.S. Fish and
Wildlife Service (USFWS), California Department of Fish and Wildlife (CDFW),
and the East Contra Costa County Habitat Conservancy, including, photos and a
breeding habitat assessment, is required prior to disturbance of any suitable
breeding habitat. The project proponent shall also notify these parties of the
approximate date of removal of the breeding habitat at least 30 days prior to this
removal to allow USFWS or CDFW staff to translocate individuals, if requested.
USFWS or CDFW must notify the project proponent of their intent to translocate
California red-legged frog within 14 days of receiving notice from the project
proponent. The project proponent must allow USFWS or CDFW access to the site
prior to construction if they request it.
There are no restrictions under the East Contra Costa County Habitat Conservation
Plan/Natural Community Conservation Plan on the nature of the disturbance or the
date of the disturbance unless CDFW or USFWS notify the project proponent of
their intent to translocate individual California red-legged frogs within the required
time period. In this case, the project proponent must coordinate the timing of
disturbance of the breeding habitat to allow USFWS or CDFW to translocate the
individual California red-legged frogs.
USFWS and CDFW shall be allowed 45 days to translocate individual California
red-legged frogs from the date the first written notification was submitted by the
project proponent (or a longer period agreed to by the project proponent, USFWS,
and CDFW).
MM-BIO-4 California Tiger Salamander Minimization. Written notification to U.S. Fish and
Wildlife Service (USFWS), California Department of Fish and Wildlife (CDFW),
and the East Contra Costa County Habitat Conservancy, including photos and
breeding habitat assessment, is required prior to disturbance of any suitable
breeding habitat. The project proponent will also notify these parties of the
approximate date of removal of the breeding habitat at least 30 days prior to this
removal to allow USFWS or CDFW staff to translocate individual California Tiger
Salamander, if requested. USFWS or CDFW must notify the project proponent of
their intent to translocate California tiger salamanders within 14 days of receiving
notice from the project proponent. The project proponent must allow USFWS or
CDFW access to the site prior to construction if they request it.
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-27
There are no restrictions under the HCP/NCCP on the nature of the disturbance or
the date of the disturbance unless CDFW or USFWS notify the project proponent
of their intent to translocate individual California tiger salamanders within the
required time period. In this case, the project proponent must coordinate the timing
of disturbance of the breeding habitat to allow USFWS or CDFW to translocate the
individuals. USFWS and CDFW shall be allowed 45 days to translocate individuals
from the date the first written notification was submitted by the project proponent
(or a longer period agreed to by the project proponent, USFWS, and CDFW).
MM-BIO-5 Rare Plant Surveys and Mitigation. Prior to commencement of any project-related
construction activity, Contra Costa County shall retain a qualified biologist/botanist
to conduct protocol-level special-status plant surveys of the undisturbed areas of
the project site for alkali milk-vetch (Astragalus tener var. tener), brittlescale
(Atriplex depressa), big tarplant (Blepharizonia plumosa), round-leaved filaree
(California macrophylla), Congdon’s tarplant (Centromadia parryi ssp.
congdonii), recurved larkspur (Delphinium recurvatum), spiny-sepaled button-
celery (Eryngium spinosepalum), diamond-petaled poppy (Eschscholzia
rhombipetala), and Contra Costa goldfields (Lasthenia conjugens), and any other
required surveys from the HCP/NCCP application for coverage
As part of the East Contra Costa County Habitat Conservation Plan (HCP)/Natural
Community Conservation Plan (NCCP) application for coverage, the surveys shall
be conducted during the appropriate blooming periods. The surveys shall be
conducted by a qualified biologist knowledgeable of the plant species in the region.
These plant surveys shall be conducted in accordance with 2009 California
Department of Fish and Wildlife (CDFW) rare plant survey protocols.
If any special-status plant species are observed during surveys, the project
proponent shall notify the HCP/NCCP Implementing Entity (i.e., East Contra Costa
County Habitat Conservancy) of the construction schedule so as to allow the
HCP/NCCP Implementing Entity the option to salvage the population(s) in
accordance with HCP/NCCP Conservation Measure 3.10 (Plant Salvage when
Impacts are Unavoidable) described below. Additionally, the project proponent
shall confirm with the HCP/NCCP Implementing Entity that the take limits of the
HCP/NCCP for the species identified have not been reached.
The following special-status plant species with potential to occur on the project site
are covered by the HCP/NCCP: brittlescale, big tarplant, round-leaved filaree, and
recurved larkspur. Alkali milk-vetch, diamond-petaled poppy, and Contra Costa
goldfields are analyzed in the HCP/NCCP but are “no take” species, and avoidance
is the only acceptable mitigation measure.
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-28
Congdon’s tarplant and spiny-sepaled button-celery are not addressed in the
HCP/NCCP. For these plants, mitigation shall consist of, in order of preference, (1)
avoidance, (2) salvage and transplant as described below, or (3) off-site habitat
enhancement or restoration in consultation with CDFW.
Plant Salvage when Impacts are Unavoidable (Covered Species)
Perennial Covered Plants
Where impacts to covered plant species cannot be avoided and plants will be
removed by approved covered activities, the HCP/NCCP Implementing Entity has
the option of salvaging the covered plants. Salvage methods for perennial species
will be tested for whole individuals, cuttings, and seeds. Salvage measures will
include the evaluation of techniques for transplanting as well as germinating seed
in garden or greenhouse and then transplanting to suitable habitat sites in the field.
Techniques will be tested for each species, and appropriate methods will be
identified through research and adaptive management. Where plants are
transplanted or seeds distributed to the field they shall be located in preserves in
suitable habitat to establish new populations. Field trials will be conducted to
evaluate the efficacy of different methods and determine the best methods to
establish new populations. New populations will be located such that they
constitute separate populations and do not become part of an existing population of
the species, as measured by the potential for genetic exchange among individuals
through pollen or propagule (e.g., seed, fruit) dispersal.
Transplanting within the preserves will only minimally disturb existing native
vegetation and soils. Supplemental watering may be provided as necessary to
increase the chances of successful establishment, but must be removed following
initial population establishment. See also “All Covered Plants,” below.
Annual Covered Plants
For annual covered plants, mature seeds will be collected from all individuals for
which impacts cannot be avoided (or if the population is large, a representative
sample of individuals). If storage is necessary, seed storage studies shall be
conducted to determine the best storage techniques for each species. If needed,
studies will be conducted on seed germinated and plants grown to maturity in
garden or greenhouse to propagate larger numbers of seed. Seed propagation
methods will ensure that genetic variation is not substantially affected by
propagation (i.e., selection for plants best adapted to cultivated conditions). Field
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-29
studies will be conducted through the Adaptive Management Program to determine
the efficacy and best approach to dispersal of seed into suitable habitat. Where
seeds are distributed to the field, they will be located in preserves in suitable habitat
to establish new populations. If seed collection methods fail (e.g., due to excessive
seed predation by insects), alternative propagation techniques shall be necessary.
See also “All Covered Plants,” below.
All Covered Plants
All salvage operations will be conducted by the East Contra Costa County Habitat
Conservancy. To ensure enough time to plan salvage operations, project proponents
will notify the East Contra Costa County Habitat Conservancy of their schedule for
removing the covered plant population.
The East Contra Costa County Habitat Conservancy may conduct investigations
into the efficacy of salvaging seeds from the soil seed bank for both perennial and
annual species. The soil seed bank may add to the genetic variability of the
population. Covered species may be separated from the soil though
garden/greenhouse germination or other appropriate means. Topsoil taken from
impact sites will not be distributed into preserves because of the risk of spreading
new non-native and invasive plants to preserves.
The HCP/NCCP Implementing Entity will transplant new populations such that
they constitute separate populations and do not become part of an existing
population of the species, as measured by the potential for genetic exchange among
individuals through pollen or propagule (e.g., seed, fruit) dispersal. Transplanting
or seeding “receptor” sites (i.e., habitat suitable for establishing a new population)
should be carefully selected on the basis of physical, biological, and logistical
considerations (Fiedler and Laven 1996); some examples of these are listed below:
• Historic range of the species.
• Soil type.
• Soil moisture.
• Topographic position, including slope and aspect.
• Site hydrology.
• Mycorrhizal associates (this may be important for Mount Diablo
manzanita).
• Presence or absence of typical associated plant species.
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-30
• Presence or absence of herbivores or plant competitors.
• Site accessibility for establishment, monitoring, and protection from
trampling by cattle or trail users.
MM-BIO-6
a. Wetlands and Waters of the United States or State. Prior to commencement of any
project-related construction activity, Contra Costa County (County) shall retain a
qualified biologist or wetland scientist to prepare a jurisdictional delineation of the
project site to determine the extent of potentially jurisdictional features within the
project disturbance area. Impacts to wetlands and other waters of the United States
or waters of the state shall require authorization from the U.S. Army Corps of
Engineers in the form of a Clean Water Act (CWA) Section 404 Permit, from the
Regional Water Quality Control Board in the form of a CWA Section 401 Water
Quality Certification, and the California Department of Fish and Wildlife in the
form of a California Fish and Game Code Section 1602 Streambed Alteration
Agreement. Such permits typically include measures to avoid and minimize or
mitigate impacts. Where avoidance of jurisdictional wetlands or waters is not
feasible, replacement of resources is required in the form of restoration or creation.
The project shall seek coverage under the East Contra Costa County HCP/ NCCP
and will mitigate for impacts to jurisdictional waters or wetlands. If neither
avoidance nor coverage under the HCP/NCCP is feasible, the County shall comply
with the requirements of the 404 permit coverage for on- or off-site mitigation, at a
replacement ration of no less than 1:1.
b. Brushy Creek Setback. Per the requirements of the HCP/NCCP and Contra Costa
County General Plan policy, a development setback of 75 feet from Brushy Creek
(measured from top of bank) is required. Note that a lesser setback (for an area less
than 300 linear feet) may be approved in consultation with the East Contra Costa
County Habitat Conservancy.
MM-BIO-7 Alkali Grassland Avoidance and Mitigation. A portion of the aviation development
area, adjacent to the existing facilities, includes alkali grassland. Ultimate development
of this site shall require either avoidance, or establishment of like alkali grassland
outside of the development area, which shall be made under consultation with the East
Contra Costa County Habitat Conservancy. Because this area is relatively disturbed, is
isolated from similar habitat, and is maintained on an on-going basis by airport staff, it
does not represent an exemplary patch of alkali grassland. Thus, mitigation ratios shall
not exceed 1:0.5 (acres disturbed, acres restored/created). Mitigation ratios for
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-31
impacts to alkali grassland will be determined in consultation with the East Contra
Costa County Habitat Conservancy.
MM-BIO-8 San Joaquin Kit Fox Preconstruction Surveys, Avoidance and Minimization, and
Construction Monitoring. Prior to any ground disturbance related to covered
activities, a USFWS/ CDFW-approved biologist will conduct a preconstruction
survey in areas identified in the planning surveys as supporting suitable breeding
or denning habitat for San Joaquin kit fox. The surveys will establish the presence
or absence of San Joaquin kit foxes and/or suitable dens and evaluate use by kit
foxes in accordance with USFWS survey guidelines (USFWS 1999).
Preconstruction surveys will be conducted within 30 days of ground disturbance.
On the parcel where the activity is proposed, the biologist will survey the proposed
disturbance footprint and a 250-foot radius from the perimeter of the proposed
footprint to identify San Joaquin kit foxes and/or suitable dens. Adjacent parcels
under different land ownership will not be surveyed. The status of all dens will be
determined and mapped. Written results of preconstruction surveys will be
submitted to USFWS within 5 working days after survey completion and before the
start of ground disturbance. Concurrence is not required prior to initiation of
covered activities.
If San Joaquin kit foxes and/or suitable dens are identified in the survey area, the
measures described below will be implemented.
• If a San Joaquin kit fox den is discovered in the proposed development
footprint, the den will be monitored for 3 days by a USFWS/CDFW–
approved biologist using a tracking medium or an infrared beam camera to
determine if the den is currently being used.
• Unoccupied dens should be destroyed immediately to pre vent
subsequent use.
• If a natal or pupping den is found, USFWS and CDFW will be notified
immediately. The den will not be destroyed until the pups and adults have
vacated and then only after further consultation with USFWS and CDFW.
• If kit fox activity is observed at the den during the initial monitoring period,
the den will be monitored for an additional 5 consecutive days from the time
of the first observation to allow any resident animals to move to another den
while den use is actively discouraged. For dens other than natal or pupping
dens, use of the den can be discouraged by partially plugging the entrance
with soil such that any resident animal can easily escape. Once the den is
determined to be unoccupied it may be excavated under the direction of the
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-32
biologist. Alternatively, if the animal is still present after 5 or more
consecutive days of plugging and monitoring, the den may have to be
excavated when, in the judgment of a biologist, it is temporarily vacant (i.e.,
during the animal’s normal foraging activities).
If dens are identified in the survey area outside the proposed disturbance footprint,
exclusion zones around each den entrance or cluster of entrances will be
demarcated. The configuration of exclusion zones should be circular, with a radius
measured outward from the den entrance(s). No covered activities will occur within
the exclusion zones. Exclusion zone radii for potential dens will be at least 50 feet
and will be demarcated with four to five flagged stakes. Exclusion zone radii for
known dens will be at least 100 feet and will be demarcated with staking and
flagging that encircles each den or cluster of dens but does not prevent access to
the den by kit fox.
MM-BIO-9 Eastern Contra Costa County Habitat Conservation Plan (HCP)/Natural
Community Conservation Plan (NCCP) Covered Shrimp Preconstruction Survey,
Avoidance and Minimization, and Construction Monitoring. Prior to any ground
disturbance related to covered activities, a U.S. Fish and Wildlife Service (USFWS)-
approved biologist will conduct a preconstruction survey in areas identified in the
planning surveys as having suitable shrimp habitat. The surveys will establish the
presence or absence of covered shrimp and/or habitat features and evaluate use by
listed shrimp in accordance with modified USFWS survey guidelines (USFWS
1996b). Project proponents are required to conduct USFWS protocol surveys in 1 year
(rather than 2) to determine presence or absence of listed shrimp species. If covered
shrimp are absent from the site, there are no further requirements related to covered
shrimp. If covered shrimp are present, the following avoidance and minimization and
construction monitoring measures are required.
To the maximum extent practicable, impacts on occupied habitat of covered shrimp
will be avoided by implementing the following measures based on existing
mitigation standards (USFWS 1996a).
• If suitable habitat for covered shrimp will be retained on site, establish a
buffer (described below) from the outer edge of all hydric vegetation
associated with seasonal wetlands occupied by covered shrimp.
Alternatively, at the request of the project proponent, representatives of the
East Contra Costa County Habitat Conservancy and USFWS may conduct
site visits to inspect the particular characteristics of specific project sites and
may approve reductions of the buffer. Buffer reductions may be approved
for all or portions of the site whenever reduced setbacks will maintain the
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-33
hydrology of the seasonal wetland and achieve the same or greater habitat
values as would be achieved by the original buffer.
• Activities inconsistent with the maintenance of seasonal wetlands within the
buffers and disturbance of the on-site watershed will be prohibited.
Inconsistent activities include altering existing topography; placing new
structures within the buffers; dumping, burning, and/or burying garbage or
any other wastes or fill materials; building new roads or trails; removing or
disturbing existing native vegetation; installing storm drains; and using
pesticides or other toxic chemicals.
• Filling of seasonal wetlands, if unavoidable, will be delayed until pools are
dry and samples from the top 4 inches of wetland soils are collected. Soil
collection will be sufficient to include a representative sample of plant and
animal life present in the wetland by incorporating seeds, cysts, eggs,
spores, and similar inocula. The amount of soil collected will be determined
by the size of the wetland filled and the variation in physical and biological
conditions within the wetland. The number and size of samples will be
sufficient to capture this variation. For very small wetlands it may be most
cost effective to simply collect all topsoil. These samples will be provided
to the East Contra Costa County Habitat Conservancy so that the soil can
be translocated to suitable habitat within the inventory area unoccupied by
covered shrimp or used to inoculate newly created seasonal wetlands on
preserve lands.
• Seasonal wetlands occupied by covered shrimp that are filled will be offset
by preserving or acquiring seasonal wetlands occupied by the covered
shrimp species and restoring habitat suitable for the covered shrimp species
in accordance with Conservation Measure 3.8. Such mitigation will
supersede requirements for mitigation of impacts on wetland habitat when
covered species are present.
If suitable habitat for covered shrimp will be retained on site, project proponents
will establish a buffer from the outer edge of all hydric vegetation associated with
seasonal wetlands occupied (or assumed to be occupied) by covered shrimp. This
buffer zone will be determined in the field by the biologists as the immediate
watershed feeding the seasonal wetland or a minimum of 50 feet, whichever is
greater. Buffers will be marked by brightly colored fencing or flagging throughout
the construction process. Activities will be prohibited within this buffer in
accordance with the minimization measure above.
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-34
Construction personnel will be trained to avoid affecting shrimp. A qualified biologist
approved by USFWS will inform all construction personnel about the life history of
covered shrimp, the importance of avoiding their habitat, and the terms and conditions
of the HCP/NCCP related to avoiding and minimizing impacts on covered shrimp.
MM-BIO-10 Eastern Contra Costa County Habitat Conservation Plan (HCP)/Natural
Community Conservation Plan (NCCP) Permit Coverage and Take Authorization.
Prior to construction or any ground disturbance, the project proponent shall obtain
permit coverage under the HCP/NCCP. The applicant will receive take
authorization under the County’s incidental take permit from the United States Fish
and Wildlife Service (USFWS) issued pursuant to Section 10(a)(1)(B) of the
Federal Endangered Species Act (permit number: TE 160958-0) and the County’s
incidental take permit from the California Department of Fish and Wildlife
(CDFW) issued pursuant to California Fish and Wildlife Code Section 2835 (permit
number 2835-2007-01-03). The project proponent shall comply with all applicable
HCP/NCCP requirements, including, but not limited to, submitting a complete
HCP/NCCP application package (see Chapter 6.2 of the HCP/NCCP), complying
with applicable avoidance, minimization and mitigation measures (see Chapter 6.4
of the HCP/NCCP), and paying the HCP/NCCP development fee (see Chapter 9.3.1
of the HCP/NCCP).
Prior to construction or any ground disturbance, the HCP/NCCP mitigation fees as
detailed in the approved HCP/NCCP application package will be paid. However, rather
than pay applicable fees, the County may choose to mitigate impacts from future
development at the Byron Airport by implementing an avoidance and preservation
program in and around the airport property as detailed in the HCP/NCCP.
Prior to construction or any ground disturbance, and in accordance with the
approved HCP/NCCP application package, a construction monitoring plan shall be
submitted to CDD and the East Contra Costa County Habitat Conservancy for
review and approval in accordance with the HCP/NCCP.
3.3.6 Level of Significance After Mitigation
Implementation of MM-BIO-1 through MM-BIO-5, and MM-BIO-8, and MM-BIO-9 through MM-
BIO-10 would reduce Impact 3.3-1 to less than significant. Implementation of MM- BIO-6, and MM-
BIO-7, and MM-BIOI-10 would reduce Impact 3.3-2 to less than significant. Implementation of MM-
BIO-6 would reduce Impact 3.3-3 to less than significant. Overall, with implementation of mitigation
measures, project impacts to special-status species, sensitive natural communities, and wetlands would
be less than significant.
3.3 – BIOLOGICAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.3-35
3.3.7 Cumulative Impacts
Development of the proposed project would result in the potential removal of, conversion of, or
other impacts to 137.35 acres of annual grassland, 1.45 acres of alkali grassland, 16.66 acres of
ruderal grassland, 2.33 acres of seasonal wetland, 2.05 acres of alkali wetland, 1.65 acres of urban
habitat, and 1.27 acres of stream habitat.
Uses of the additional build-out at the airport would be consistent with on-going activities at the
current airport and would not significantly increase operational noise, light, or other indirect
factors that may affect local and migratory wildlife.
In conclusion, the proposed project would not result in significant or unavoidable cumulative
impacts when considered on a regional scale.

3.4 CULTURAL RESOURCES
This section describes the existing cultural resources of the Byron Airport Development Program
(project) site, identifies associated regulatory requirements, evaluates potential impacts, and
identifies mitigation measures to reduce the proposed project’s potentially significant impacts to
less-than-significant levels. Prehistoric resources include sites and artifacts associated with the
indigenous, non-Euro-American population, generally prior to contact with people of European
descent. Historical resources consist of structures, features, artifacts, and sites that date from Euro-
American settlement of the region.
This section is based on the Cultural Resources Inventory Report prepared for the project by Dudek
in May 2019 (Appendix E).
3.4.1 Existing Conditions
The 1,319-acre project site is located in southeastern Contra Costa County, approximately 2.5
miles south of the community of Byron, California. Byron Airport is located on the western edge
of the flat Sacramento–San Joaquin Delta agricultural lands, giving way to rolling hills and
grasslands west of the airport. The project site is relatively flat land that contains two
nonintersecting runways, each with a parallel taxiway and several connector taxiways. Aviation
facilities are generally concentrated in the “V” formed by the two runways, with approximately 10
acres of aircraft storage area, 4 acres of apron, 125,000 square feet of hangars, and 2,400 square
feet of office space. The majority of these facilities were constructed when the airport was built in
the early 1990s. The project site historically supported agricultural fields from at least 1949 until
1966, when the project site was graded for roads and runways for a previous private airport facility.
On-site elevations range from 30 to 100 feet above mean sea level. Approximately 814 acres of
airport property south and west of the airfield are set aside as a wildlife preserve. An existing
residence is located within the northeast corner of the project site, between the existing airport
property and the Byron Bethany Irrigation District Canal. The airport owns an additional 120 acres
north of Armstrong Road that is not considered part of the project site or the cultural resources
study area.
3.4.1.1 Prehistory Background
In general, the archaeology and prehistory of the Central Valley are not well understood. In
addition, much of the archaeological material from the valley area has not been found in context,
having been scavenged from the surface and placed in private collections. Early and widespread
agricultural use of the valley floor has destroyed much of the bottomland archaeology, and siltation
has most likely buried many resources well below the surface sediments. On the valley floor, in
the southern Central Valley, fluted projectile points were found at the Witt Site, suggesting
possible Clovis occupation in the region earlier than 11,000 years ago, during the Pleistocene.
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-2
Other evidence for Early Holocene occupation around valley lakes has been recovered from Buena
Vista Lake (Appendix E).
More than two decades ago, a general chronological framework was provided by Moratto (1984) that
encompasses the Central Valley. Since then, numerous additional studies have provided data to
supplement and refine this framework. Building on this previous research, the following chronology
contains four general time frames with associated periods, dates, and marker traits: Paleoindian
(Paleoindian Period), Early Archaic (Early Period), Middle Archaic (Middle Period), and Late Archaic
(Late Period). A description of each of these periods is presented in Appendix E.
The region surrounding the project site would have been at the southern extent of Northern Valley
Yokut tribal territory during the ethnohistoric period. This group inhabited the lower San Joaquin
River watershed and its tributaries extending from Calaveras River in the north to approximately
the large bend of the San Joaquin River eastward near Mendota. The lower San Joaquin River
meanders through the territory making bends, sloughs, and marshes full of tule reeds as it
meanders. Farther from the rivers and marshes, the valley floor would have been dry and sparsely
vegetated (Appendix E).
Northern Valley Yokut habitation areas were most commonly situated in close proximity to the San
Joaquin River and its major tributaries, more often on the east side of the river. West of the river
populations were much sparser and concentrated in the foothills on minor waterways. This focus on
waterways can also be seen in their dietary resources, which included various fish, waterfowl,
antelope, elk, acorns, tule roots, and various seeds. In particular, and in contrast to their San Joaquin
Valley Yokut neighbors, salmon was an abundant food during the fall spawning and in springtime.
The focus on fishing is also seen in the material culture consisting of net sinkers and harpoons, likely
used from rafts constructed from tule reed bundles (Appendix E).
Traditional village were perched on top of low mounds on or near riverbanks. Northern Valley
Yokut dwellings were constructed of tule reed woven mats placed over a pole frame oval or round
structure. They were usually 25–40 feet in diameter and would belong to a single family. This is
in contrast to the larger multifamily dwellings erected sometimes by the Southern Yokuts. In
addition to dwellings, earth covered ceremonial sweat lodges were constructed. There was a high
level of sedentism due to abundant riverine resources, though there were times of seasonal
disbandment for harvesting wild plant resources such as acorns and seeds (Appendix E).
The Northern Valley Yokuts saw sharp and devastating decline from disease and relocation to
coastal missions nearly immediately after Spanish contact. This only increased with the large
influx of cattle ranching and Anglos Americans after the gold rush.

3.4.1.2 History of the Project Area
The following sections describe the relevant history of California, the region, and the project vicinity.
Spanish Period (1769–1822)
Gaspar de Portolá entered San Francisco Bay in 1769. Additional explorations of San Francisco
Bay and the plains to the east were conducted by Captain Pedro Fages in 1772 and Juan Bautista
De Anza in 1776. In 1808, Lieutenant Gabriel Moragain led the first Spanish expedition into the
Sacramento Valley. This group explored areas in the American, Calaveras, Cosumnes, Feather,
Merced, Mokelumne, Sacramento, and Stanislaus river watersheds. The most recent Spanish
expedition into this region was conducted by Luis Arguello in 1817. This group traveled up the
Sacramento River to the mouth of the Feather River.
Spanish missionization of Alta California was initiated at San Diego in 1769. A total of 21 missions
were constructed by the Dominican and Franciscan orders between 1769 and 1823. Missions in
the region included San Francisco de Asís (1776), Santa Clara de Asís (1776), San José de
Guadalupe (1797 in Alameda County), San Rafael Arcángel (1817 in Marin County), and San
Francisco Solano (1823 in Sonoma County) (Grunsky 1989). While missionization had a
detrimental effect on tribes throughout the region, there is no record of forcible transport of
Nisenan communities by the Spanish to the missions.
Mexican Period (1822–1848)
Mexico’s separation from the Spanish empire in 1821 and the secularization of the California
missions in the 1830s caused further disruptions to native populations. Following establishment of
the Mexican republic, the government seized many of the lands belonging to Native Americans,
providing them as parts of larger land grants to affluent Mexican citizens and rancheros. Captain
John Sutter was granted the two largest areas of land in the Sacramento Valley area. Sutter founded
New Helvetia, a trading and agricultural empire, in 1839. The headqu arters was located within
Valley Nisenan territory at the confluence of the Sacramento and American rivers. The 1833
Secularization Act passed by the Mexican Congress ordered half of all mission lands to be
transferred to the Native Americans, and the other half to remain in trust and managed by an
appointed administrator. These orders were never implemented due to several factors that
conspired to prevent the Native Americans from regaining their patrimony.
American fur trappers and traders conducted a number of exploratory intrusions into west Sierra
Nevada Mexican territory. Notably, in 1826, Jedediah Smith led a small party of trappers in an
expedition along the Sierra Nevada range, eventually entering the Sacramento Valley in 1827. This
group covered the area along the American and Cosumnes rivers. From these travels, maps of this
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-4
inhospitable terrain were created and disseminated, providing for the waves of European
prospectors, ranchers, and settlers who would come in the following decades.
American Period (Post-1848)
California has been inexorably shaped by the mining of precious metals and other minerals. The
discovery of gold in January of 1848 at Sutter’s Mill in Coloma, on the South Fork of the American
River, led to extensive and enduring changes to California’s physical and cultural landscapes. The
California gold rush, prompted by news of the find at Sutter’s Mill, led to what has been
characterized as the greatest mass migration in American history. Within months of the initial
discovery, gold was being collected in the gravel bars of the North, Middle, and South Forks of
the American River, and extensive placer mining was occurring in nearly every adjacent gulch and
ravine. The effects of these activities are still evident in the form of tailin gs, ditches, and other
mining features scattered throughout these areas. Mining can also be credited for the location and
names of most of the towns and communities in the region, the placement of early transportation
and communication corridors between the western Sierra Nevada, Sacramento, and San Francisco,
and the subsequent development of agriculture and ranching throughout the foothills and valley
(Appendix E).
As the allure of gold mining declined, agriculture and ranching in the Central Valley became more
prominent and productive economic pursuits in the region (Davis 1975). Stockton, located
approximately 20 miles from the project site, turned into the valley’s major agricultural shipping
point. With the grain exporting opportunities of World War II, the city accelerated in growth
(Haslam et al. 1993) to become the prominent urban center in the vicinity of the project site. In
1868, Orange Risdon Jr. and Lewis Risdon Mead took initial steps to develop and market the
Byron Hot Springs into a rural health resort. The town of Byron was founded in 1878, concurrently
with the introduction of track laid through the area by the San Pablo and Tulare Railroad Company
(East County Historical Society). A hotel, which remarkably for the time had hot and cold water,
was constructed at the site of the hot springs in 1888. This initial hotel burned down in 1901 and,
again, a re-built hotel burned in 1912 (Kyle 2002). The third hotel, having enjoyed decades of
popularity, closed in 1938 following broader trends of diminished public interest in mineral springs
as health destinations. In 1969, 2,200 acres of land were inundated next to the project site to create
a temporary storage pool and regulating reservoir within the tidally influenced region of the
Sacramento-San Joaquin Delta for the California Aqueduct, creating the Clifton Court Forebay
(Kano 1990).
3.4.1.3 Records Search
A records search was completed for a 0.5-mile radius around the project site by staff at the
Northwest Information Center at Sonoma State University, California, on March 22, 2016. The
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-5
records search indicated that 55 previous cultural resources technical investigations have been
conducted in this area. Of these studies, nine cover all or a portion of the project site. The records
search identified one cultural resource, P-07-002547 (Byron Bethany Irrigation District Main
Canal No. 9), within the project development area; four cultural resources (P-07-000320, P-07-
000321, P-07- 002707, and P-07-002708) located within the Byron Airport parcel boundary; and
an additional seven cultural resources occur within the 0.5-mile search radius of the project site.
Of the 12 previously recorded resources, there is one prehistoric artifact scatter, seven historic-age
canals/aqueducts, one historic railroad segment, one historic road segment, one historic rock
foundation, and one unknown resource due to missing record. Two (P-07-002547 and P-07-
000813) of the 12 cultural resources have been evaluated and were determined not eligible for
National Register of Historic Places (NRHP) and California Register of Historical Resources
(CRHR) listing.
P-07-000320/CA-CCO-550
This historic site was originally recorded by L.K. Napton and E.A. Greathouse in 1987 as part of
the cultural resource investigation of the East Contra Costa County Airport Five-Year
Development Plan Project. The site consists of a rock foundation composed of 54 large sandstone
rocks with associated historic refuse. The crew reported site disturbance and attributed the
disturbances to rodent bioturbation activities. In 2005, Sean Dexter and Armando Cuellar revisited
the site as part of the cultural resources reconnaissance for the Byron Airport Master Plan. The
crew observed that the site had been entirely destroyed by construction of a Byron Airport runway
and taxiway. No evidence of the site remains.
P-07-000321/CA-CCO-551
This prehistoric site was originally recorded by L.K. Napton and E.A. Greathouse in 1987 as part
of the cultural resource investigation of the East Contra Costa County Airport Five-Year
Development Plan Project. The site consists of a hammerstone, core, hand stone fragment, and
lithic flakes. The crew noted that the site had been disturbed by washes, drainage overflow, and
possibly impacted from previous gas line construction for the airport. Miller, Crabtree, Oshins,
and Chavez revisited the site in 1990. They did not relocate the original lithic flakes or core;
however, the crew did observe a hammerstone fragment, possible hand stone, and fire-affected
rock fragments with charcoal. In 2005, Sean Dexter and Armando Cuellar revisited the site as part
of the cultural resources reconnaissance for the Byron Airport Master Plan. It was observed that
the site had been disturbed by construction of Falcon Way and construction activities associated
with the gas line found within the site boundary. Despite the disturbances, there is still potential
for the site to contain an undisturbed component that could be significant. The archaeologists
recommended archaeological testing for this site to determine if the site is eligible for listing on
the CRHR.
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-6
P-07-002547/CA-CCO-738
This historic resource was first recorded by Tracy Bakic and Cinder Baker in 2001. This resource
consists of the Byron Bethany Irrigation District Main Canal No. 9. This segment of the canal is
located on the southeast side of the California Aqueduct. Baker, of Par Environmental, conducted
an evaluation of the canal to determine if the historic resource was significant. The Byron Bethany
Irrigation District site was determined not eligible for listing on the CRHR or under California
Environmental Quality Act (CEQA) criteria. Sean Dexter and Armando Cueller also conducted a
cultural reconnaissance in 2005 for three segments of the canal located within Contra Costa County
(Assessor’s Parcel Numbers 001-011-011, 001-031-014, 001-031-013, and 001-031-016) as part
of the cultural resources reconnaissance for the Byron Airport Master Plan. The crew observed
that Segment 2 appears to have been completely rebuilt circa 1990 for construction of the main
Byron Airport runway; Segment 3 is a short segment that has been abandoned since 1990; and
Segment 4 showed evidence of being partially rebuilt in 1968 and around 1990 for construction of
Byron Airport. The 2005 study determined that the three segments are not eligible for listing on
the CRHR or under CEQA criteria.
P-07-002707
This historic feature was recorded by Sean Dexter and Armando Cueller in 2005, as part of the
cultural resources reconnaissance for the Byron Airport Master Plan. The resource consists of an
exposed 8.5-inch diameter steel pipe aqueduct which is supported on concrete cradles. This
aqueduct pipe may date back to the original 1917 Byron Bethany Irrigation District system as it is
depicted as emerging from the Irrigation District Main Canal No. 9 on the U.S. Geological Survey
topographic map. The archaeologists recommended archaeological investigations to determine if
this resource is eligible on the CRHR.
P-07-002708
This historic resource was recorded in 2005 by Sean Dexter and Armando Cueller, as part of the
cultural resources reconnaissance for the Byron Airport Master Plan. This resource consists of an
abandoned segment of Byron Hot Springs Road. The crew observed that the road has been stripped
of all pavement and was abandoned during the construction of Byron Airport in the early 1990s.
South of Runway 5-23, within the airport fencing area, a remnant of the road is still visible. The
archaeologists recommended archaeological investigations to determine if this resource is eligible
on the CRHR.
3.4.1.4 Sacred Lands File Search and Tribal Consultation
A search of the Native American Heritage Commission (NAHC) Sacred Lands File (SLF) was
requested on February 22, 2016, for the project site. The NAHC results, received March 1, 2016,
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-7
did not indicate the presence of Native American cultural resources in or near the project site. The
NAHC also provided a contact list of Native American individuals and/or tribal organizations who
may have direct knowledge of cultural resources in or near the project site. Following the NAHC
response, letters were sent on April 8, 2016, to the listed tribal representatives to solicit
information, opinions, or concerns relating to potential project impacts. These letters contain a
brief description of the project, reference maps, and a summary of the NAHC SLF search results.
No response to these outreach attempts has been received to date.
In addition, the County sent letters to all Native American tribes that have requested notification,
per Assembly Bill (AB) 52 and Senate Bill 18. A request for consultation was received from
Wilton Rancheria on August 30, 2017. The County emailed the tribal contact on September 7,
2017, and again on February 22, 2018, attempting to coordinate consultation. No response was
received at that time. Consultation is considered closed. During the public comment period for the
Draft EIR, an additional consultation request letter was received by the County from the Wilton
Rancheria on July 14, 2021. The County re-opened consultation on September 22, 2021. Although
no tribal cultural resources were identified within the project site, minor modifications were made
to the mitigation measures addressing accidental discovery of tribal cultural resources.
Consultation was again closed on January 21, 2022.
3.4.1.5 Pedestrian Survey
An intensive-level pedestrian survey of most of the entire project site was conducted on May 10,
2016, using standard archaeological procedures and techniques. One previously recorded resource,
P-07-002547, was observed during the field survey. This resource occurs within the aviation
development area. One newly identified built environment feature (temporarily designated as BA-
KL-1) was identified within the project development area, located north of the intersection of
Byron Hot Springs Road and Holey Road. BA-KL-1 consists of a historic wooden corral that is
possibly associated with the ranch/agricultural property located directly north (outside of Byron
Airport parcel boundary) of the corral.
Documentation of BA-KL-1 complied with the Office of Historic Preservation and Secretary of
the Interior’s Standards and Guidelines for Archaeology and Historic Preservation (48 FR 44716-
44740) and the California Office of Historic Preservation Planning Bulletin Number 4(a). Newly
identified BA-KL-1 was recorded on California Department of Parks and Recreation Form DPR
523L (Series 1/95) Continuation Sheet, using the Instructions for Recording Historical Resources
(Office of Historic Preservation 1995). Dudek determined that data potential for BA-KL-1 has
been exhausted through field-level recordation. The resource does not have the potential to further
yield information locally, regionally, or nationally beyond field level. BA-KL-1 is not eligible for
listing on the CRHR or the local register and is not significant under CEQA. The Department of
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-8
Parks and Recreation form will be submitted to the Northwest Information Center. No other
cultural resources, historical resources, or historic properties were identified in the project site.
A subsequent pedestrian survey was conducted on November 28, 2018, of the 11.7-acre parcel for
potential acquisition, and the potential off-site infrastructure locations (the seven study
intersections discussed in Section 3.13, Transportation, and the roadway segments of Armstrong
Road, Byron Hot Springs Road, and Holey Road between the airport and Byron Highway). No
additional cultural resources were observed in this additional area.
3.4.2 Relevant Plans, Policies, and Ordinances
The treatment of cultural resources is governed by federal, state, and local laws and guidelines.
There are specific criteria for determining whether prehistoric and historic sites or objects are
significant and/or protected by law. Federal and state significance criteria generally focus on the
resource’s integrity and uniqueness, its relationship to similar resources, and its potent ial to
contribute important information to scholarly research. Some resources that do not meet federal
significance criteria may be considered significant by state criteria. The laws and regulations seek
to mitigate impacts on significant prehistoric or historic resources. The federal, state, and local
laws and guidelines for protecting historic resources are summarized below.
Federal
National Historic Preservation Act
The National Historic Preservation Act of 1966 established the NRHP as the official federal list of
cultural resources that have been nominated by state offices for their historical significance at the
local, state, or national level. Properties listed in the NRHP, or determined eligible for listing, must
meet certain criteria for historical significance and possess integrity of form, location, and setting.
Under Section 106 of the act and its implementing regulations, federal agencies are required to
consider the effects of their actions, or those they fund or permit, on properties that may be eligible
for listing or that are listed in the NRHP. The regulations in Title 36 of the Code of Federal
Regulations, Section 60.4, describe the criteria to evaluate cultural resources for inclusion in the
NRHP. Properties may be listed in the NRHP if they possess integrity of location, design, setting,
materials, workmanship, feeling, and association, and they:
A. Are associated with events that have made a significant contribution to the broad patterns
of our history;
B. Are associated with the lives of persons significant in our past;
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-9
C. Embody the distinctive characteristics of a type, period, or method of construction, or
represent the work of a master, or possess high artistic values, or represent a significant
and distinguishable entity whose components may lack individual distinction; or
D. Have yielded, or may be likely to yield, information important in prehistory or history.
These factors are known as Criteria A, B, C, and D.
In addition, the resource must be at least 50 years old, except in exceptional circumstances. Eligible
properties must meet at least one of the criteria and exhibit integrity, which is measured by the
degree to which the resource retains its historical properties and conveys its historical character,
the degree to which the original fabric has been retained, and the reversibility of the changes to the
property. Archaeological sites are generally evaluated under Criterion D, which concerns the
potential to yield information important in prehistory or history.
The Section 106 review process, typically undertaken between the U.S. Army Corps of Engineers
as part of issuing a Section 404 permit and the State Historic Preservation Officer, involves a four-
step procedure:
• Initiate the Section 106 process by establishing the undertaking, developing a plan for
public involvement, and identifying other consulting parties.
• Identify historic properties by determining the scope of efforts, identifying cultural
resources, and evaluating their eligibility for inclusion in the NRHP.
• Assess adverse effects by applying the criteria of adverse effect on historic properties
(resources that are eligible for inclusion in the NRHP).
• Resolve adverse effects by consulting with the State Historic Preservation Officer and other
consulting agencies, including the Advisory Council on Historic Preservation, if necessary,
to develop an agreement that addresses the treatment of historic properties.
The Department of the Interior has set forth Standards and Guidelines for Archaeology and
Historic Preservation. These standards and guidelines are not regulatory and do not set or interpret
agency policy. A project that follows the standards and guidelines generally shall be considered
mitigated to a less-than-significant level, according to Section 15064.5(b)(3) of the CEQA
Guidelines (14 CCR 15000 et seq.). Because it is not a federal agency, Contra Costa County is not
subject to the National Historical Preservation Act, including Section 106.
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-10
State
California Environmental Quality Act
Under CEQA, public agencies must consider the effects of their actions on both historical
resources and unique archaeological resources. Pursuant to California Public Resources Code
(PRC), Section 21084.1, a “project that may cause a substantial adverse change in the significance
of an historical resource is a project that may have a significant effect on the environment.” PRC,
Section 21083.2, requires agencies to determine whether proposed projects would have effects on
“unique archaeological resources.”
“Historical resource” is a term of art with a defined statutory meaning (PRC 21084.1; 14 CCR
15064.5[a], 15064.5[b]). The term embraces any resource listed in or determined to be eligible for
listing in the CRHR. The CRHR includes resources listed in or formally determined eligible for listing
in the NRHP, as well as some California State Landmarks and Points of Historical Interest.
Properties of local significance that have been designated under a local preservation ordinance
(local landmarks or landmark districts) or that have been identified in a local historical resources
inventory may be eligible for listing in the CRHR and are presumed to be historical resources for
purposes of CEQA unless a preponderance of evidence indicates otherwise (PRC 5024.1; 14 CCR
4850). Unless a resource listed in a survey has been demolished or has lost substantial integrity,
or there is a preponderance of evidence indicating that it is otherwise not eligible for listing, a lead
agency should consider the resource potentially eligible for the CRHR.
In addition to assessing whether historical resources potentially impacted by a proposed project
are listed or have been identified in a survey process, lead agencies have a responsibility to evaluate
them against the CRHR criteria prior to making a finding as to a proposed project’s impacts to
historical resources (PRC 21084.1; 14 CCR 15064.5[a][3]). In general, a historical resource, under
this approach, is defined as any object, building, structure, site, area, place, record, or manuscript
that:
A. Is historically or archaeologically significant, or is significant in the architectural,
engineering, scientific, economic, agricultural, educational, social, political, or cultural
annals of California; and
B. Meets any of the following criteria:
1. Is associated with events that have made a significant contribution to the broad patterns
of California’s history and cultural heritage;
2. Is associated with the lives of persons important in our past;
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-11
3. Embodies the distinctive characteristics of a type, period, region, or method of
construction, or represents the work of an important creative individual, or possesses
high artistic values; or
4. Has yielded, or may be likely to yield, information important in prehistory or history
(CEQA Guidelines, Section 15064.5[a][3]).
These factors are known as Criteria 1, 2, 3, and 4 and parallel Criteria A, B, C, and D under the
National Historic Preservation Act. The fact that a resource is not listed or determined to be eligible
for listing does not preclude a lead agency from determining that it may be a historical resource
(PRC 21084.1; 14 CCR 15064.5[a][4]).
CEQA also distinguishes between two classes of archaeological resources: archaeological sites
that meet the definition of a historical resource, as described above, and unique archaeological
resources. Under CEQA, an archaeological resource is considered “unique” if it:
• Contains information needed to answer important scientific research questions and there is
a demonstrable public interest in that information;
• Has a special and particular quality such as being the oldest of its type or the best available
example of its type; or
• Is directly associated with a scientifically recognized important prehistoric or historic event
or person (PRC 21083.2[g]).
CEQA states that if a proposed project would result in an impact that might cause a substantial
adverse change in the significance of a historical resource, then an environmental impact report
(EIR) must be prepared, and mitigation measures and alternatives must be considered. A
“substantial adverse change” in the significance of a historical resource means physical demolition,
destruction, relocation, or alteration of the resource or its immediate surroundings such that the
significance of a historical resource would be materially impaired (14 CCR 15064.5[b][1]).
The CEQA Guidelines Section 15064.5(c) also provides specific guidance on the treatment of
archaeological resources, depending on whether they meet the definition of a historical resource
or a unique archaeological resource. If the site meets the definition of a unique archaeological
resource, it must be treated in accordance with the provisions of PRC 21083.2.
CEQA Guidelines Section 15126.4(b) sets forth principles relevant to means of mitigating impacts
on historical resources. It provides as follows:
(1) Where maintenance, repair, stabilization, rehabilitation, restoration, preservation,
conservation or reconstruction of the historical resource will be conducted in a
manner consistent with the Secretary of the Interior's Standards for the Treatment
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-12
of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring,
and Reconstructing Historic Buildings (1995), Weeks and Grimmer, the project’s
impact on the historical resource shall generally be considered mitigated below a
level of significance and thus is not significant.
(2) In some circumstances, documentation of an historical resource, by way of
historic narrative, photographs, or architectural drawings, as mitigation for the
effects of demolition of the resource will not mitigate the effects to a point
where clearly no significant effect on the environment would occur.
(3) Public agencies should, whenever feasible, seek to avoid damaging effects
on any historical resource of an archaeological nature. The following factors
shall be considered and discussed in an EIR for a project involving such an
archaeological site:
(A) Preservation in place is the preferred manner of mitigating impacts to
archaeological sites. Preservation in place maintains the relationship
between artifacts and the archaeological context. Preservation may also
avoid con flict with religious or cultural values of groups associated with
the site.
(B) Preservation in place may be accomplished by, but is not limited to,
the following:
1. Planning construction to avoid archaeological sites;
2. Incorporation of sites within parks, greenspace, or other open space;
3. Covering the archaeological sites with a layer of chemically stable
soil before building tennis courts, parking lots, or similar facilities
on the site.
4. Deeding the site into a permanent conservation easement.
(C) When data recovery through excavation is the only feasible mitigation, a data
recovery plan, which makes provision for adequately recovering the
scientifically consequential information from and about the historical resource,
shall be prepared and adopted prior to any excavation being undertaken. Such
studies shall be deposited with the California Historical Resources Regional
Information Center. Archaeological sites known to contain human remains
shall be treated in accordance with the provisions of Section 7050.5 Health and
Safety Code. If an artifact must be removed during project excavation or
testing, curation may be an appropriate mitigation.
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-13
(D) Data recovery shall not be required for an historical resource if the lead
agency determines that testing or studies already completed have
adequately recovered the scientifically consequential information from and
about the archaeological or historical resource, provided that the
determination is documented in the EIR and that the studies are deposited
with the California Historical Resources Regional Information Center.
CEQA and the California Public Records Act restrict the amount of information regarding cultural
resources that can be disclosed in an EIR in order to avoid the possibility that such resources could
be subject to vandalism or other damage (Clover Valley Foundation v. City of Rocklin [2011] 197
Cal.App.4th 200, 219). The state CEQA Guidelines prohibit an EIR from including “information
about the location of archaeological sites and sacred lands, or any other information that is subject
to the disclosure restrictions of Section 6254 of the Government Code.” (14 CCR 15120[d]). In
turn, California Government Code (GC) Section 6254 of the California Public Records Act lists
as exempt from public disclosure any records “of Native American graves, cemeteries, and sacred
places and records of Native American places, features, and objects described in Sections 5097.9
and 5097.933 of the [California] Public Resources Code maintained by, or in the possession of,
the Native American Heritage Commission, another state agency, or a local agency” (GC Section
6254[r]). The Public Records Act also generally prohibits disclosure of archaeological records.
GC Section 6254.10 provides: “Nothing in [the California Public Records Act] requires disclosure
of records that relate to archaeological site information and reports maintained by, or in the
possession of…a local agency, including the records that the agency obtains through a consultation
process between a California Native American tribe and a state or local agency.”
PRC, Sections 5097.9 and 5097.993, list the Native American places, features, and objects, the
records of which are not to be publicly disclosed under the California P ublic Records Act: “any
Native American sanctified cemetery, places of worship, religious or ceremonial site, or sacred
shrine located on public property” (Section 5097.9) and any “Native American historic, cultural,
or sacred site, that is listed or may be eligible for listing in the California Register of Historic
Resources…, including any historic or prehistoric ruins, any burial ground, any archaeological or
historic site, any inscriptions made by Native Americans at such a site, any archaeological or
historic Native American rock art, or any archaeological or historic feature of a Native American
historic, cultural, or sacred site” (Section 5097.993[a][1]).
CEQA Guidelines Section 15064.5(e) requires that excavation activities be stopped whenever
human remains are uncovered and that the county coroner be called in to assess the remains. If the
county coroner determines that the remains are those of Native Americans, the NAHC must be
contacted within 24 hours. At that time, the lead agency must consult with the appropriate Native
Americans, if any, as identified in a timely manner by the NAHC. Section 15064.5 of the CEQA
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-14
Guidelines directs the lead agency (or applicant), under certain circumstances, to develop an
agreement with the Native Americans for the treatment and disposition of the remains.
Senate Bill 297
This law addresses the disposition of Native American burials in archaeological sites and protects
such remains from disturbance, vandalism, or inadvertent destruction; establishes procedures to be
implemented if Native American skeletal remains are discovered during construction; and
establishes the NAHC to resolve disputes regarding the disposition of such remains. Senate Bill
297 has been incorporated into Section 15064.5(e) of the CEQA Guidelines.
Senate Bill 18
Senate Bill 18 requires local governments to consult with tribes prior to making certain planning
decisions and to provide notice to tribes at certain key points in the planning process. These
consultation and notice requirements apply to adoption and amendment of general plans (defined
in GC Section 65300 et seq.) and specific plans (defined in GC Section 65450 et seq.).
Assembly Bill 52
AB 52 requires consultation with Native American tribes traditionally and culturally affiliated with
the geographic area in which a project requiring CEQA review is proposed if those tribes have
requested to be informed of such proposed projects. The intention of such consultation is to avoid
adverse impacts to tribal cultural resources (TCRs). This law is in addition to legislation protecting
archaeological resources associated with California Native American tribes. In addition, AB 52
defines TCRs as a significant environmental issue under CEQA. AB 52 applies to all projects
initiating environmental review in or after July 2015.
California Health and Safety Code
Section 7050.5(b) of the California Health and Safety Code specifies protocols to address any
human remains that may be discovered. The code states the following:
In the event of discovery or recognition of any human remains in any location other
than a dedicated cemetery, there shall be no further excavation or disturbance of
the site or any nearby area reasonably suspected to overlie adjacent remains until
the coroner of the county in which the human remains are discovered has
determined, in accordance with Chapter 10 (commencing with section 27460) of
Part 3 of Division 2 of Title 3 of the Government Code, that the remains are not
subject to the provisions of section 27492 of the Government Code or any other
related provisions of law concerning investigation of the circumstances, manner
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-15
and cause of death, and the recommendations concerning treatment and disposition
of the human remains have been made to the person responsible for the excavation,
or to his or her authorized representative, in the manner provided in section 5097.98
of the Public Resources Code.
California Environmental Quality Act
Under CEQA, state and public agencies are required to investigate mitigation measures that would
reduce significant environmental effects of proposed projects. If paleontological resources are
identified during an environmental assessment of a project, then the sponsoring agency must take
the resources into consideration when evaluating project effects.
California Public Resources Code Section 5097.5
Section 5097.5 of the PRC protects historic or prehistoric ruins, burial grounds, archaeological or
vertebrate paleontological sites, or any other archaeological, paleontological, or historical feature
that is situated on land owned by, or in the jurisdiction of, the State of California, or any city,
county, district, authority, or public corporation, or any agency thereof.
Local
Contra Costa County General Plan
The Open Space Element of the Contra Costa County General Plan contains the following goal
and policies pertaining to archaeological and historic cultural resources (Contra Costa County
2005):
Goal 9-G To identify and preserve important archaeological and historic resources within the
county.
Policy 9-28 Areas which have identifiable and important archaeologic or historic
significance shall be preserved for such uses, preferably in public
ownership.
Policy 9-29 Buildings or structures that have visual merit and historic value shall
be protected.
Policy 9-30 Development surrounding areas of historic significance shall have
compatible and high-quality design in order to protect and enhance
the historic quality of the area.
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-16
Policy 9-31 Within the Southeast County area, applicants for subdivision or land
use permits to allow non-residential uses shall provide information
to the County on the nature and extent of the archaeological
resources that exist in the area. The County Planning Agency shall
be responsible for determining the balance between multiple use of
the land and protection of resources.
3.4.3 Thresholds of Significance
The significance criteria used to evaluate the project’s impacts to cultural resources and tribal
cultural resources are based on Appendix G of the CEQA Guidelines. According to Appendix G,
a significant impact would occur if the project would:
1. Cause a substantial adverse change in the significance of a historical resource as defined
in CEQA Guidelines Section 15064.5.
2. Cause a substantial adverse change in the significance of an archaeological resource
pursuant to CEQA Guidelines Section 15064.5.
3. Disturb any human remains, including those interred outside of dedicated cemeteries.
4. 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), or
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. In applying the criteria set forth in subdivision (c) of
Public Resource Code Section 5024.1, the lead agency shall consider the significance
of the resource to a California Native American tribe.
3.4.4 Impacts Analysis
Impact 3.4-1. The project may cause a substantial adverse change in the significance of a
historical resource as defined in CEQA Guidelines Section 15064.5.
(Potentially Significant)
The CEQA Guidelines provide that a project that demolishes or alters those physical characteristics
of a historical resource that convey its historical significance (i.e., its character-defining features)
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-17
can be considered to materially impair the resource’s significance. In order to best mitigate the
effects of the project on cultural resources, a reasonable, good-faith effort must be applied to
determining their historical character and eligibility for listing in the CRHR (PRC Section 5024.1;
14 CCR 4852).
Based on existing records (records search and historic aerials), the eastern portion of the project
site was used for agriculture from approximately the early 1900s to 1993. The majority of the
Byron Airport property, except for the northwestern portion where a smaller airport was located
from 1966 to 1993, was left as open grasslands until Byron Airport was built. The newly recorded
historic-age resource, BA-KL-1, consists of a wooden corral. The records indicate that the corral
is associated with the property located just north of the resource. According to historic topographic
maps, the property served as a school from 1914 to 1948. By 1955, and on, the school was no
longer being used as such. Only a building location is shown on the maps. The earliest hist oric
aerial for the property is 1949. This photograph shows the property as being an agricultural
residence/private property with the wooden corral located just south of the property. Photographs
from 1949, 1959, 1966, 1968, 1979, 1993, 2005, 2009, and 2010 do not reveal any changes to the
property and corral locations. The residence is outside of the project site and would not be impacted
by the project.
CEQA Guidelines were used in determining the significance of BA-KL-1. It was found that BA-
KL-1, while speaking to the presence and types of activities that occurred historically concerning
agriculture, is not associated with any known significant events locally, regionally, or nationally
(Criterion 1); the wooden corral, on its own, does not provide information that would be associated
with the lives of any important people locally, regionally, or nationally (Criterion 2); it does not
contain intact or individual distinction (Criterion 3); and since all data potential for BA-KL-1 has
been exhausted through field-level recordation, this resource does not have the potential to further
yield information locally, regionally, or nationally (Criterion 4). The resource is not eligible for
listing on the CRHR or the local register and is not significant under CEQA. California Department
of Parks and Recreation 523 series forms were completed for the site (confidential appendix to the
Cultural Resources Study). As such, no further work is recommended for this resource.
Byron Bethany Irrigation District Main Canal No. 9 was evaluated by Par Environmental in 2001
and Condor Country Consulting in 2005 as not being eligible for listing under the NRHP or CRHR.
The canal does not retain sufficient integrity after being impacted by construction of Byron Airport
in the early 1990s. The canal also lacks association with any significant important people locally,
regionally, or nationally. In addition to the wooden corral and Byron Bethany Irrigation District
Main Canal No. 9, which were found in the project site, four cultural resources (P-07-000320, P-
07-000321, P-07-002707, and P-07-002708) are recorded within the Byron Airport parcel
boundary, and an additional seven cultural resources are recorded within the 0.5-mile search radius
of the project site. Of the 11 previously recorded resources outside of the project site, six are
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-18
historic age canals/aqueducts, one is a historic railroad segment, one is a historic road segment,
one is a historic rock foundation, and one is an unknown resource due to missing record. Two (P-
07-002547 and P-07-000813) of the 12 cultural resources have been evaluated and were
determined not eligible for NRHP and CRHR listing. The project is not expected to impact these
historic age resources as they are located outside of the project site.
Based on available information, it appears that no historical resources, as defined under CEQA,
would be impacted by the project. However, due to the presence of cultural resources within the
eastern portion of the project site, it is possible that additional historical resources would
inadvertently be discovered during construction. This is a potentially significant impact.
Impact 3.4-2. The project may cause a substantial adverse change in the significance of an
archaeological resource pursuant to CEQA Guidelines Section 15064.5.
(Potentially Significant)
The Cultural Resources Inventory Report prepared for the project found that, although no
previously recorded archaeological resources were found in the project site, four cultural resources
were recorded within the Byron Airport parcel boundary, and an additional seven cultural
resources were identified within the 0.5-mile search radius of the project site (Appendix E). Of
these resources, one is a prehistoric artifact scatter, and another is an unknown resource due to
missing record. The remaining resources are historic-age, and therefore are not considered
archaeological. The NAHC SLF search did not identify cultural resources within the project site.
Because the project would not impact areas outside of the project site, it would not cause a
substantial adverse change to a known archaeological resource. However, the Cultural Resources
Inventory Report suggests that there is moderate potential for inadvertent discovery of intact
cultural deposits during earth moving activities (Appendix E). Because of this, the project would
have a potentially significant impact on archaeological resources.
Impact 3.4-3. The project may disturb human remains, including those interred outside of
dedicated cemeteries. (Potentially Significant)
No previously recorded human remains were identified during the records search or Native
American consultation. The pedestrian survey also found no indication of human remains.
Nevertheless, it is possible that human remains would inadvertently be discovered during
construction. Disturbance of previously unidentified human remains would be a potentially
significant impact.
Impact 3.4-4. The project would not 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
3.4 – CULTURAL RESOURCES
Byron Airport Development Program EIR 9269
February 2022 3.4-19
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); or
b. A resource determined by the lead agency, in its discretion and supported by su bstantial
evidence, to be significant pursuant to criteria set forth in subdivision (c) of Public
Resources Code Section 5024.1. In applying the criteria set forth in subdivision (c) of
Public Resource Code Section 5024.1, the lead agency shall consider the significance of
the resource to a California Native American tribe. (Potentially Significant)
Dudek contacted the NAHC to request a review of the SLF. The NAHC responded to Dudek’s request,
stating that the SLF search was conducted with negative results. The County sent letters to all California
Native American tribes traditionally and culturally affiliated with the project site requesting notification
pursuant to AB 52. As discussed in Section 3.4.1.4, Wilton Rancheria requested consultation in 2017,
but two attempts by the County to schedule consultation were not answered by the tribal contact. No
information regarding the potential presence of a TCR was provided. During the public comment
period for the Draft EIR, an additional consultation request letter was received by the County from
the Wilton Rancheria on July 14, 2021. The County re-opened consultation. Although no tribal
cultural resources were identified within the project site, minor modifications were made to the
mitigation measures addressing accidental discovery of tribal cultural resources.
As described previously, the CHRIS records search conducted for the proposed project identified
one prehistoric resource located on the project site. The presence of this resource and the proximity
of Byron Hot Springs to the project site indicates there is the potential to inadvertently encounter
TCRs during construction. This is a potentially significant impact.
3.4.5 Mitigation Measures
No historical or unique archaeological resources eligible for listing under the NRHP or CRHR
have been identified on the project site. The following mitigation measures would reduce the
potential for impacts on previously unidentified cultural resources or human remains.
MM-CUL-1 Accidental Discovery of Archaeological Resources. Prior to commencement
of any construction activities involving ground disturbance, Contra Costa
County, a qualified archaeologist, representatives from interested Native
American Tribes, and the construction contractor shall be invited to meet or
otherwise discuss by conference call the project site’s archaeological sensitivity
and determine the duration and extent of monitoring for archaeological deposits

condition in some locations surrounding existing airport facilities, areas of
elevated potential for encountering unanticipated resources should be
considered those within 500 feet of the historic-era corral and Brushy Creek,
and no deeper than 4 feet below the present ground surface. An archaeological
monitor and a monitor from a culturally affiliated Native American Tribe shall
be present for initial ground-disturbing work in these areas, after which the
monitoring frequency shall be reduced to periodic spot-checks elsewhere. The
monitoring strategy shall be adjusted (increased, decreased, or discontinued)
based on the results of monitoring within areas of elevated archaeological
sensitivity and as recommended by a qualified archaeologist meeting the
Secretary of the Interior’s Professional Qualification Standards, in consultation
with culturally affiliated Native American Tribes. In the event that
archaeological resources are exposed, work within 100 feet of the find shall be
halted or directed to another location until a qualified archaeologist can evaluate
the significance of the find. If the resources are determined to be historical
resources or unique (pursuant to Section 15064.5 of the CEQA Guidelines), the
qualified archaeologist shall make recommendations prioritizing resource
avoidance, or, where avoidance is infeasible, data recovery.
MM-CUL-2 Accidental Discovery of Human Remains. Pursuant to Section 5097.98 of the
California Public Resources Code and Section 7050.5 of the California Health
and Safety Code, as well as California Environmental Quality Act Guidelines
Section 15064.5(e), in the event of the discovery of human remains, work shall
be suspended within 100 feet of the find, and the Contra Costa County (County)
Coroner/Sheriff shall be immediately notified. The County Coroner/Sheriff
shall determine if an investigation is necessary. If the remains are determined
to be Native American:
1. The Coroner shall contact the Native American Heritage Commission
(NAHC) within 24 hours.
2. The NAHC shall identify the person or persons it believes to be the most
likely descendant (MLD) from the deceased Native American.
3. The MLD shall have an opportunity to make a recommendation to the
County for means of treating or disposing of, with appropriate dignity, the
human remains and any associated grave goods as provided in California
Public Resources Code, Section 5097.98.
MM-CUL-3 Should a potential tribal cultural resource (TCR) be inadvertently encountered,
construction activities within 100 feet of the TCR shall be halted and Contra

notified. The Department shall notify Native American tribes that have been
identified by the Native American Heritage Commission to be traditionally and
culturally affiliated with the geographic area of the project. Any affected tribe
shall be provided a reasonable period of time to conduct a site visit and make
recommendations regarding future ground disturbance activities as well as the
treatment and disposition of any discovered TCR. Depending on the nature of
the potential resource and tribal recommendations, review by a qualified
archaeologist may be required. Implementation of proposed recommendations
shall be made based on the determination of the County that the approach is
reasonable and feasible. All activities shall be conducted in accordance with
regulatory requirements.
MM-CUL-4 Worker Environmental Awareness Program (WEAP). The County shall
require the contractor to provide a cultural resources and tribal cultural resources
sensitivity and awareness training program (Worker Environmental Awareness
Program [WEAP]) for all personnel involved in project construction, including
field consultants and construction workers. The WEAP shall be developed in
coordination with an archaeologist meeting the Secretary of the Interior’s
Professional Qualifications Standards for Archeology, as well as culturally
affiliated Native American tribes. The County will invite Native American
representatives from interested culturally affiliated Native American tribes to
participate. The WEAP shall be conducted before any ground-disturbing
construction activities begin at the project site. The WEAP shall include relevant
information regarding sensitive cultural resources and tribal cultural resources,
including applicable regulations, protocols for avoidance, and consequences of
violating State laws and regulations.
The WEAP shall also describe appropriate avoidance and impact minimization
measures for cultural resources and tribal cultural resources that could be located
at the project site and shall outline what to do and who to contact if any potential
cultural resources or tribal cultural resources are encountered. The WEAP shall
emphasize the requirement for confidentiality and culturally appropriate
treatment of any discovery of significance to Native Americans and shall discuss
appropriate behaviors and responsive actions, consistent with Native American
tribal values.

3.4.6 Level of Significance After Mitigation
Implementation of MM-CUL-1 would reduce Impact 3.4-1 and Impact 3.4-2 to less than
significant. Implementation of MM-CUL-2 would reduce Impact 3.4-3 to less than significant.
Implementation of MM-CUL-3 would reduce Impact 3.4-4 to less than significant.
3.4.7 Cumulative Impacts
The geographic scope of the cumulative impact analysis for the evaluation of potential cumulative
impacts on cultural resources is southeastern Contra Costa County (the area which reasonably
relates to the historical development of the community of Byron and exceeds the normal survey
area for an archaeological records search).
Subsurface prehistoric resources are expected to be confined to the territory of the Northern Valley
Yokut, which includes the lower San Joaquin River watershed and its tributaries extending from
Calaveras River in the north to approximately the large bend of the San Joaquin River eastward
near Mendota. Historic resources and prehistoric sites have been recorded in the vicinity of Byron
and could occur elsewhere in southeastern Contra Costa County. Development in the region could
result in the damage or destruction of known and unknown archaeological and historical resources,
as well as any existing undiscovered subsurface artifacts. The cumulative impact from past,
present, and probable future projects, as well as the proposed project, is potentially significant.
As described in Section 3.4.4, Impacts Analysis, the proposed project would not impact any known
historical or archaeological resources. However, the inadvertent destruction of resources during
site preparation and construction of the proposed project, if not properly treated, would result in
the project incrementally contributing to a significant cumulative impact.
Numerous laws, regulations, and statutes, on both the federal and state levels, seek to protect
cultural resources. These would apply to development within and outside Byron. In addition, the
County General Plan provides local policies that safeguard cultural resources from unnecessary
impacts (Contra Costa County 2005). These policies include identification and preservation of
important archaeological and historical resources and balancing land uses with protection of
cultural resources. Because the project site contains a moderate likelihood for the discovery of
unknown subsurface historical or prehistoric resources, the project’s contribution to the cumulative
loss of cultural resources is potentially significant. However, with implementation of MM-CUL-
1 through MM-CUL-3, described above, impacts would be less than significant.

3.5 GEOLOGY, SOILS, AND MINERALS
This section describes the existing geological setting of the Byron Airport Development Program
(project) site, identifies associated regulatory requirements, evaluates potential impacts, and
identifies mitigation measures related to implementation of the proposed project.
3.5.1 Existing Conditions
The project site consists of the Byron Airport, approximately 1,307 acres south of Armstrong
Road, and the approximately 12-acre parcel located between the airport property and the Bethany
Irrigation District Canal, for a total of 1,319 acres. The airport reference elevation is 76 feet above
mean sea level. The project site is relatively flat land that contains two nonintersecting runways,
each with a parallel taxiway and several connector taxiways. The project site is located in
southeastern Contra Costa County (County), approximately 2.5 miles south of the community of
Byron, California. The airport is located on the western edge of the flat Sacramento-San Joaquin
Delta agricultural lands, giving way to rolling hills and grasslands west of the airport. General
aviation facilities are generally concentrated in the “V” formed by the two runways, with
approximately 10 acres of aircraft storage area, 4 acres of apron, 125,000 square feet of hangars,
and 2,400 square feet of office space. The majority of these facilities were constructed when the
airport was built in the early 1990s. The project site historically supported agricultural fields from
at least 1949 until 1966, when the project site was graded for roads and airport runways. On-site
elevations range from 30 to 100 feet above mean sea level. Approximately 814 acres of airport
property to the south and west of the airfield are set aside as a wildlife preserve.
3.5.1.1 Seismic Hazards
Faults
The project lies within a region of California that contains many active and potentially active faults
and is considered an area of high seismic activity. Earthquakes are recorded by a seismographic
network. Each seismic station in the network measures the movement of the ground at the site.
The slip of one block of rock over another in an earthquake releases energy that makes the ground
vibrate. That vibration pushes the adjoining piece of ground and causes it to vibrate, and thus the
energy travels out from the earthquake in a wave. There are many different ways to measure
different aspects of an earthquake. Magnitude is the most common measure of an earthquake's
size. It is a measure of the size of the earthquake source and is the same number no matter where
you are or what the shaking feels like. The Richter scale is an outdated method that is no longer
used that measured the largest wiggle on the recording; other magnitude scales measure different
parts of the earthquake (USGS 2018).
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-2
Ground movement during an earthquake can vary depending on the overall magnitude, distance to
the fault, focus of earthquake energy, and type of geologic material. The composition of underlying
soils, even those relatively distant from faults, can intensify ground shaking. For this reason,
earthquake intensities are also measured in terms of their observed effects at a given locality. The
Modified Mercalli intensity scale is commonly used to measure earthquake damage due to ground
shaking. The Modified Mercalli values for intensity range from I (earthquake not felt) to XII
(damage nearly total) and intensities ranging from IV to X could cause moderate to significant
structural damage. The intensity of an earthquake will vary over the region of a fault and generally
decrease with distance from the epicenter of the earthquake.
The California Geological Survey (CGS) Probabilistic Seismic Hazard Assessment calculates
earthquake shaking hazards through historic seismic activity and fault slip rates. Shaking from
faults is expressed as the peak ground acceleration (PGA) measured as a percentage (or fraction)
of acceleration due to gravity from ground motion that has a 10% probability of being exceeded
in 50 years. The project site is located in an area with a PGA of 40%–50% (0.40g) (DOC 2018).
Regional Faults
The San Andreas, Hayward, and Calaveras faults pose the greatest threats of significant damage
in the Bay Area according to the U.S. Geological Survey (USGS) Working Group on California
Earthquake Probabilities (USGS 2003a). These three faults exhibit strike-slip orientation and have
experienced movement within the last 150 years. Other principal faults capable of producing
significant ground shaking in the Bay Area include the Concord–Green Valley, Marsh Creek–
Greenville, and Rodgers Creek faults. Table 3.5-1 provides historic earthquake and surface
faulting, known micro seismic activity, and estimated maximum probable earthquake information
for the regional faults.
San Andreas Fault
The San Andreas fault zone is a major structural feature that forms at the boundary between the
North American and Pacific tectonic plates, extending from the Salton Sea in Southern California
near the border with Mexico to north of Point Arena, where the fault trace extends out into the
Pacific Ocean. The main trace of the San Andreas fault through the Bay Area trends northwest
through the Santa Cruz Mountains and the eastern side of the San Francisco Peninsula. As the
principal strike-slip boundary between the Pacific plate to the west and the North American plate
to the east, the San Andreas is often a highly visible topographic feature, such as between Pacifica
and San Mateo, where Crystal Springs Reservoir and San Andreas Lake clearly mark the rupture
zone. Near San Francisco, the San Andreas fault trace is located immediately offshore near Daly
City and continues northwest through the Pacific Ocean approximately 6 miles due west of the
Golden Gate Bridge. In the San Francisco Bay Area, the San Andreas fault zone was the source of
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-3
the two major seismic events in recent history that affected the San Francisco Bay region. The
1906 San Francisco earthquake was estimated at moment magnitude (Mw) 7.9 and resulted in
approximately 290 miles of surface fault rupture, the longest of any known continental strike slip
fault. Horizontal displacement along the fault approached 17 feet near the epicenter. The more
recent 1989 Loma Prieta earthquake, with a magnitude of Mw 6.9, resulted in widespread damage
throughout the Bay Area.
Hayward Fault
The Hayward fault zone is the southern extension of a fracture zone that includes the Rodgers
Creek fault (north of San Pablo Bay), the Healdsburg fault (Sonoma County) and the Maacama
fault (Mendocino County). The Hayward fault trends to the northwest within the East Bay,
extending from San Pablo Bay in Richmond, 60 miles south to San Jose. The Hayward fault in
San Jose converges with the Calaveras fault, a similar type of fault that extends north to Suisun
Bay. The Hayward fault is designated by the Alquist-Priolo Earthquake Fault Zoning Act as an
active fault. Historically, the Hayward fault generated one sizable earthquake in the 1800s. In 1868,
a Richter magnitude 7 earthquake on the southern segment of the Hayward fault ruptured the
ground for a distance of about 30 miles. Recent analysis of geodetic data indicates surface
deformation may have extended as far north as Berkeley. Lateral ground surface displacement
during these events was at least 3 feet (USGS 2003a).
A characteristic feature of the Hayward fault is its well-expressed and relatively consistent fault
creep. Although large earthquakes on the Hayward fault have been rare since 1868, slow fault
creep has continued to occur and has caused measurable offset. Fault creep on the East Bay
segment of the Hayward fault is estimated at 9 millimeters per year (Peterson et al. 1996).
However, a large earthquake could occur on the Hayward fault with an estimated Mw of about 7.1.
The USGS Working Group includes the Hayward–Rodgers Creek fault systems in the list of those
faults that have the highest probability of generating earthquakes of magnitude 6.7 or greater in
the Bay Area (USGS 2003b).
Calaveras Fault
The Calaveras fault is a major right-lateral strike-slip fault that has been active during the last 11,000
years. The Calaveras fault is located in the eastern San Francisco Bay region and generally trends along
the eastern side of the East Bay Hills, west of San Ramon Valley, and extends into the western Diablo
Range and eventually joins the San Andreas fault zone south of Hollister. The northern extent of the
fault zone is somewhat conjectural and could be linked with the Concord fault.
The fault separates rocks of different ages, with older rocks west of the fault and younger
sedimentary rocks to the east. The location of the main, active fault trace is defined by youthful
geomorphic features (linear scarps and troughs, right-laterally deflected drainage, sag ponds) and
3.5 – GEOLOGY, SOILS, AND MINERALS

local groundwater barriers. The Calaveras fault is designated as an Alquist-Priolo Earthquake
Hazard Zone (see discussion on this zone designation below). There is a distinct change in slip
rate and fault behavior north and south of the vicinity of Calaveras Reservoir. North of Calaveras
Reservoir, the fault is characterized by a relatively low slip rate of 5–6 millimeters per year and
sparse seismicity. South of Calaveras Reservoir, the fault zone is characterized by a higher rate of
surface fault creep that has been evidenced in historic times. The Calaveras fault has been the
source of numerous moderate magnitude earthquakes and the probability of a large earthquake
(greater than magnitude 6.7) is much lower than on the San Andreas or Hayward faults (USGS
2003b). However, this fault is considered capable of generating earthquakes with upper bound
magnitudes ranging from Mw 6.6 to Mw 6.8.
Concord–Green Valley Fault
The Concord–Green Valley fault extends from Walnut Creek north to Wooden Valley (east of
Napa Valley). Historical record indicates that no large earthquakes have occurred on the Concord
or Green Valley faults (USGS 2003a). However, a moderate earthquake of magnitude 5.4 occurred
on the Concord fault segment in 1955. The Concord and Green Valley faults exhibit active fault
creep and are considered to have a small (4%) probability of causing a significant (greater than
magnitude 6.7) earthquake according to the USGS.
Greenville Fault
The Greenville fault, also known as the Marsh Creek–Greenville fault, extends along the base of
the Altamont Hills, which form the eastern margin of the Livermore Valley. The fault is recognized
as a major structural feature and has demonstrated activity in the last 11,000 years. A magnitude
5.6 earthquake on the Greenville fault in 1980 produced a small amount of surface rupture
(approximately 3 centimeters) on the fault near Vasco Road.

Ground Shaking
Ground shaking may affect areas hundreds of miles distant from the earthquake’s epicenter.
Historic earthquakes have caused strong ground shaking and damage in the San Francisco Bay
Area, the most recent being the magnitude 6.9 Loma Prieta earthquake in October 1989. The
epicenter was more than 60 miles south of the project area, but this earthquake nevertheless caused
strong ground shaking for about 20 seconds and resulted in varying degrees of structural damage
throughout the Bay Area. The 1906 San Franci sco earthquake, with an estimated Mw of 7.9,
produced moderate shaking intensities in the project area. The 1989 Loma Prieta earthquake, with
an Mw of 6.9, produced light shaking intensities in the project area (ABAG 2018).
The common way to describe ground motion during an earthquake is with the motion parameters
of acceleration and velocity in addition to the duration of the shaking. A common measure of
ground motion is the PGA. The PGA for a given component of motion is the largest value of
horizontal acceleration obtained from a seismograph. The potential hazards related to ground
shaking are discussed further in Section 3.5.4, Impacts Analysis.
Liquefaction and Landslide
Liquefaction is a specialized form of ground failure caused by earthquake ground motion. It is a
quicksand condition occurring in water-saturated, unconsolidated, relatively clay-free sands and
silts caused by hydraulic pressure (from ground motion) forcing apart soil particles and forcing
them into quicksand-like liquid suspension. In the process, normally firm, but wet, ground
materials take on the characteristics of liquids. Liquefaction is a transformation of soil from a solid
to a liquefied state during which saturated soil temporarily loses strength resulting from the buildup
of excess pore water pressure, especially during earthquake-induced cyclic loading. Soil
susceptible to liquefaction includes loose to medium dense sand and gravel, low-plasticity silt and
some low-plasticity clay deposits.
Four kinds of ground failure commonly result from liquefaction: lateral spread, flow failure, ground
oscillation, and loss of bearing strength. Liquefaction and associated failures could damage
foundations, roads, underground cables, and pipelines and disrupt utility service. In addition,
liquefaction can occur in unconsolidated or artificial fill sediments and other reclaimed areas along the
margin of San Francisco Bay. Geologically young and water-saturated sandy sediments, such as those
found in the extensive shoreline areas in western and northeastern county locations and the delta, are
highly susceptible to liquefaction. Based on the County General Plan Safety Element, the project site
has an estimated liquefaction potential of moderate to low (Contra Costa County 2005a).
Catastrophic ground failures may result from liquefaction, which pose a major threat to the safety
of engineered structures. Major landslides, settling and tilting of buildings on level ground, and
failure of water retaining structures have all been observed as a result of this type of ground failure.
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-6
It should be emphasized that great earthquakes anywhere in the Bay Area are capable of triggering
liquefaction in the County.
Landslides are the downslope movement of geologic materials. Typically, such movement occurs
as block glide (in which slope failure occurs along a planar surface and the mass of materials slides
as a single block) or as a slump (in which slope failure occurs along single or multiple surfaces
and the mass of materials slides in a rotational motion). Areas that are subject to slides and
slippages from other natural causes may be very hazardous under earthquake conditions.
Therefore, earthquake effects will be more extensive if a major earthquake occurs during the rainy
season when ground conditions are favorable to landslides and ground slippage. According to the
County General Plan Safety Element, the project site is not located in an area with landslide
deposits, reclaimed area, or filled reclaimed area, nor is the site in an area in over 26% slope
(Contra Costa County 2005a). The potential hazards related to liquefaction and landslides are
discussed further in Section 3.5.4.
3.5.1.2 Site Geology
Regional Geology
The project site lies within the geologically complex region of California referred to as the Coast
Ranges geomorphic province. The Coast Ranges province lies between the Pacific Ocean and the
Great Valley and stretches from the Oregon border to the Santa Ynez Mountains near Santa
Barbara. Much of the Coast Ranges province is composed of marine sedimentary deposits and
volcanic rocks that form northwest-trending mountain ridges and valleys, running roughly parallel
to the San Andreas fault zone. These older consolidated rocks are characteristically exposed in the
mountains but are buried beneath younger, unconsolidated alluvial fan and fluvial sediments in the
valleys and lowlands. In coastal and bay margins, these younger sediments commonly interfinger
with a variety of marine deposits (e.g., bay mud). The geology of the County is dominated by
several northwest trending fault systems which divide the County into large blocks of rock.
Site Geology
The project site is underlain by Pliocene Bedrock and Older (Pleistocene) Alluvium, which is
characterized by consolidated and unconsolidated sediments and possesses potential for expansive
clays, hillside earthflows, and unstable cut slopes. Soils of the project site are classified under the
lowland soils classification, which means these soils are slowly to very slowly permeable, highly
expansive, and corrosive, with slight erosion hazards (Contra Costa County 2005a). The project
site contains soils within the C and D hydrologic soil groups. Hydrologic soil group C is typically
comprised of 20%–40% clay and less than 50% sand, and group D soils have typically greater than
40% clay, less than 50% sand, and clayey textures.
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-7
Soil types located within the project site include the following (USDA 1977):
• Altamont clay 9%–15% slopes (AbD): The Altamont series consists of well-drained soils
underlain by shale and soft, fine-grained sandstone. Permeability is slow, and the available
water capacity is 6.5–10 inches. Roots can penetrate to a depth of 40–60 inches. This soil
is well drained, with a moderate to low erosion potential. Runoff is slow to medium where
the soil is tilled and exposed.
• Altamont clay 15%–30% slopes (AbE): This soil is on rolling hills, along narrow
drainageways, and in depressions. Runoff is medium, and the hazard of erosion is moderate
where the soil is bare.
• Fontana-Altamont complex (Fd): The Fontana series consists of well-drained soils
underlain by calcareous, fine-grained sandstone. These soils are on uplands. Permeability
is moderately slow, and the available water capacity is 3.5–6.5 inches. Roots can penetrate
to a depth of 20–36 inches. This complex is on foothills in the eastern uplands of the
County. It consists of about 55% Fontana silty clay loam and 30% Altamont clay. Runoff
is slow to medium where the soils are tilled and exposed, and the hazard of erosion is slight
to moderate.
• Linne clay loam, 5%–15% slopes (LbD): The Linne series consists of well-drained soils
underlain by calcareous, interbedded shale and soft sandstone. Permeability is moderately
slow, and the available water capacity is 4–8 inches. Roots can penetrate to a depth of 20–40
inches. This gently rolling to rolling soil is on foothills in the uplands. Runoff is slow to
medium, and the hazard of erosion is slight to moderate where the soil is tilled and exposed.
• Linne clay loam, 15%–30% slopes (LbE): This soil is moderately steep with a runoff
classification of medium, and the hazard of erosion is moderate where the soil is bare.
• Rincon clay loam 2%–9% slopes (RbC): The Rincon series consists of well-drained
soils, formed in alluvial valley fill from sedimentary rock. This gently sloping and
moderately sloping soil is on benches. These soils have a surface layer of dark reddish-
brown, neutral sandy loam, and a subsoil or reddish-brown, neutral clay loam. Runoff is
medium and the hazard of erosion is slight where the soil is tilled and exposed. Permeability
is show and the available water capacity is 9–10 inches. Roots can penetrate to a depth of
more than 60 inches.
• San Ysidro loam 0%–5% slopes (Sc): The San Ysidro series consists of moderately well
drained soils. Permeability is very slow, and the available water capacity is 3.5–5 inches.
Runoff is slow and the hazard of erosion is slight. The depth to which roots can penetrate
is limited to 10–20 inches by the clay subsoil.
• Solana loam (Sh): The Solana series consists of somewhat poorly drained soils that formed
in alluvium from sedimentary rock. Slopes are 0%–2%. Runoff is slow and the hazard of
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-8
erosion is slight. Permeability is very slow, and the available water capacity is 4–6 inches.
Roots of salt-tolerant plants can penetrate to a depth of 36–48 inches.
• Solana loam, strongly alkali (Sk): This soil is in old valley fill near rims of basins. Slopes
are 0%–2%. Runoff is slow, and the hazard of erosion is moderate.
3.5.1.3 Geologic Hazards
Expansive or Unstable Soils
Expansive soils are clay- or adobe-based soils that absorb large quantities of water and, as a result,
expand. This expansion can cause building slabs to crack and buckle. Structural damage may occur
over a long period of time, usually as the result of inadequate soil and foundation engineering or
the placement of structures directly on expansive soils. The Quaternary Alluvium underlying the
project site possesses the potential for expansive clays (Contra Costa County 2005a).
Soil Erosion
Erosion is the wearing away of soil and rock by processes such as mechanical or chemical
weathering, mass wasting, and the action of waves, wind, and underground water. Excessive soil
erosion can eventually lead to damage of building foundations and roadways. At the project site,
areas that are most susceptible to erosion are any disturbed soils located on steeper terrain.
Typically, the soil erosion potential is reduced once the soil is graded and vegetated, or covered
with concrete, structures, asphalt, or slope protection. When erosion occurs, topsoil is lost,
resulting in reduced crop productivity and sedimentation problems downstream. In turn,
sedimentation can fill waterways, diminish water quality, and damage sensitive habitats. Erosion
occurs when high rainfall, lack of cover, fragile soils, and steep slopes combine. Urbanization,
development activities, recreation, agricultural, and logging practices increase erosion (Contra
Costa County 2005a).
According to the soil survey of the County, the project site is underlain by soils characterized by
well-drained, moderately well drained, and somewhat poorly drained soils. Runoff is of the
underlying soils are characterized as, medium, slow to medium, and slow, and the soil’s potential
for erosion is slight, slight to moderate, moderate, and moderate to low (USDA 1977).
3.5.1.4 Paleontological Resources
There are nearly 15,000 Middle Miocene to Late Pleistocene vertebrate records from the County
in the University of California Museum of Paleontology specimens database. The University of
California Museum of Paleontology localities database did not indicate any recorded sites within
the vicinity of the project site (UCMP 2018). The project site is underlain by Late Cretaceous
bedrock and Older (Pleistocene) Alluvium, which is characterized by consolidated and
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-9
unconsolidated sediments. Both Alluvial fan deposits of Pleistocene age and Late Cretaceous age
bedrock are considered to have a high potential to yield paleontological resources. Numerous
stratigraphically important vertebrate fossils have been found within California’s Pleistocene
nonmarine strata, including the assemblages that define both the Rancholabrean and Irvingtonian
North American Land Mammal Ages, which are used as a reference by paleontologists and
stratigraphers across the country. Due to this, continental Pleistocene-age deposits are almost
universally considered to be of high sensitivity for paleontological resources within California
(Caltrans 2010). Late Cretaceous marine reptiles have also been discovered from the Great Valley,
and the corresponding bedrock is considered to have a high potential to yield significant
paleontological resources.
3.5.1.5 Mineral Resources
The CGS, formerly the California Division of Mines and Geology, has classified lands within the
San Francisco Bay Region into mineral resource zones (MRZs). The classification of MRZs is
based on guidelines adopted by the California State Mining and Geology Board, as mandated by
the Surface Mining and Reclamation Act of 1975. The project site is mapped by the CGS as not
containing MRZs. The County General Plan Conservation Element identifies the significant
mineral resources areas that are found within the County. The project site is not located within one
of these mineral resource areas (Contra Costa County 2005b).
3.5.2 Relevant Plans, Policies, and Ordinances
Federal
Occupational Safety and Health Administration Regulations
Excavation and trenching are among the most hazardous construction operations. The
Occupational Safety and Health Administration (OSHA) Excavation and Trenching Standard,
Title 29 of the Code of Federal Regulations, Part 1926.650, covers requirements for excavation
and trenching operations. OSHA requires that all excavations in which employees could
potentially be exposed to cave-ins be protected by sloping or benching the sides of the excavation,
supporting the sides of the excavation, or placing a shield between the side of the excavation and
the work area. In California, California OSHA has responsibility for implementing federal rules
relevant to worker safety, including slope protection during construction excavations. California
OSHA’s requirements are more restrictive and protective than federal OSHA standards.
U.S. Geological Survey Landslide Hazard Program
In fulfillment of the requirements of Public Law 106-113, the USGS created the Landslide Hazards
Program in the mid-1970s. According to the USGS, the primary objective of the National
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-10
Landslide Hazards Program is to reduce long-term losses from landslide hazards by improving
understanding of the causes of ground failure and suggesting mitigation strategies. The federal
government takes the lead role in funding and conducting this research, whereas the reduction of
losses due to geologic hazards is primarily a state and local responsibility.
State
Alquist-Priolo Earthquake Fault Zoning Act
The Alquist-Priolo Earthquake Fault Zoning Act was passed in 1972 to mitigate the hazard of
surface faulting to structures for human occupancy. In accordance with this act, the State Geologist
established regulatory zones, called “earthquake fault zones,” around the surface traces of active
faults, and published maps showing these zones. Earthquake fault zones are designated by the CGS
and are delineated along traces of faults where mapping demonstrates surface fault rupture has
occurred within the past 11,000 years. Construction within these zones cannot be permitted until
a geologic exploration has been conducted to prove that a building planned for human occupancy
would not be constructed across an active fault. These types of site evaluations address the precise
location and recency of rupture along traces of the faults, and are typically based on observations
made in trenches excavated across fault traces.
Seismic Hazards Mapping Act
The Seismic Hazards Mapping Act of 1990 (California Public Resources Code, Chapter 7.8, Section
2690 et seq.) directs the CGS to protect the public from earthquake-induced liquefaction and landslide
hazards (these hazards are distinct from fault surface rupture hazard regulated by the Alquist-Priolo
Act). This act requires the State Geologist to delineate various seismic hazard zones and requires cities,
counties, and other local permitting agencies to regulate certain development projects within these
zones (i.e., zones of required investigation). Before a development permit may be granted for a site
within a seismic hazard zone, a geotechnical exploration of the site must be conducted and appropriate
mitigation measures incorporated into project design. Evaluation and mitigation of potential risks from
seismic hazards within zones of required investigation must be conducted in accordance with the CGS
Special Publication 117A, adopted March 13, 1997, by the State Mining and Geology Board (as
updated in 2008).
As of 2012, Seismic Hazard Zone Maps have been prepared for portions of populated areas of
Southern California and the San Francisco Bay Area; however, no seismic hazard zones have yet
been delineated for the project site. As a result, the provisions of the Seismic Hazards Mapping
Act would not apply to the proposed project.

California Building Code
The California Building Code (CBC) has been codified in the California Code of Regulations as
Title 24, Part 2. Title 24 is administered by the California Building Standards Commission, which
is responsible for coordinating all building standards. Under state law, all building standards must
be centralized in Title 24 or they are not enforceable. The purpose of the CBC is to est ablish
minimum standards to safeguard the public health, safety, and general welfare through structural
strength, means of egress facilities, and general stability by regulating and controlling the design,
construction, quality of materials, use and occupancy, location, and maintenance of all building
and structures within its jurisdiction. The CBC is based on the International Building Code
published by the International Code Conference. The CBC contains California amendments based
on the American Society of Civil Engineers Minimum Design Standards 7-05. American Society
of Civil Engineers 7-05 provides requirements for general structural design and includes means
for determining earthquake loads and other loads (such as wind loads) for inclusion into building
codes. The provisions of the CBC apply to the construction, alteration, movement, replacement,
and demolition of every building or structure or any appurtenances connected or attached to such
buildings or structures throughout California.
Paleontological Resources
Paleontological resources are afforded consideration under CEQA. Appendix G of the CEQA
Guidelines (14 CCR 15000 et seq.) includes as one of the questions to be answered in the
Environmental Checklist (Appendix G, Section V, Part c) the following: “Would the project
directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?”
California Public Resources Code, Section 5097.5, specifies that any unauthorized removal of
paleontological remains is a misdemeanor. Further, California Penal Code Section 622.5 sets the
penalties for damage to or removal of paleontological resources.
Local
Contra Costa County General Plan
The County General Plan Safety Element (Safety Element) contains goals and policies related to geology,
soils, and seismicity that apply to development projects throughout the unincorporated County, including
project. These goals and policies include the following (Contra Costa County 2005a):
Goal 10-B To reduce to a practical minimum injuries and health risks resulting from the effects
of earthquake ground shaking on structures, facilities, and utilities.
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-12
Goal 10-C To protect persons and property from the life-threatening, structurally and financially
disastrous effects of ground rupture and fault creep on active faults, and to reduce
structural distress caused by soil and rock weakness due to geologic faults.
Policy 10-2 Significant land use decisions (General Plan amendment, rezoning,
etc.) shall be based on a thorough evaluation of geologic-seismic
and soils conditions and risk.
Liquefaction
The Safety Element contains a map, Estimated Liquefaction Potential, that divides the County into
three categories: “generally high,” “generally moderate to low,” and “generally low” (Contra Costa
County 2005a). This map is used as screening criteria by the County during the processing of land
development applications. The County requires rigorous evaluation of liquefaction potential in
areas of high potential, and less comprehensive investigations are demanded in areas falling within
the moderate or low category. The classification of generally high liquefaction potential does not
guarantee the presence of liquefiable sands on a parcel. The map attempts to be conservative on
the side of safety, and where geologically recent alluvial and estuarine deposits are shown on soil
maps of the County, the map depicts such properties within the generally high category. Site
specific investigations are needed to determine if liquefiable sands are present and to provide
stabilization measures where liquefiable sands are confirmed.
The Safety Element includes a number of policies indicating that at-risk areas require evaluation
of liquefaction potential and effective mitigation of the hazard posed to new development (Contra
Costa County 2005a). Where improvements are proposed in even the generally moderate to low
category, investigation of the hazard is routinely required. Where liquefiable sands are confirmed
to be present, effective measures to avoid/control damage are a prerequisite to obtaining project
approvals. Because the windswept ridge crests within the project site are in the generally low
category, quantitative evaluation of liquefaction potential is not required.
Ground Failure and Landslides
In 1975, the USGS issued photo-interpretation maps of landslides and other surficial deposits of
the County (scale: 1 inch = 2000 feet). That mapping is presented on pages 10–24 of the Safety
Element (Contra Costa County 2005a). According to the map, there are landslides within the
project site.
It should be recognized that the USGS slides are mapped solely on the basis of photointerpretation,
without the benefit of a site visit or any subsurface data. The landslides are not classified on the
basis of the activity status (i.e., active or dormant), depth of slide plane (shallow or deep seated),
or type of landslide deposit. Nevertheless, the map fulfills its function, which is to red flag sites
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-13
that may be at risk of landslide damage, where detailed geologic and geotechnical investigations
are required to evaluate risks and develop measures to reduce risks to a practical minimum. The
Safety Element includes a number of policies that require evaluation of geologic hazards for land
development projects proposed in areas of potential hazards. The Safety Element states that
geologic conditions should be a primary determinant of land use (Contra Costa County 2005a).
3.5.3 Thresholds of Significance
The significance criteria used to evaluate the project impacts to geology and soils are based on
Appendix G of the CEQA Guidelines. According to Appendix G of the CEQA Guidelines, a
significant impact related to geology, soils, and minerals would occur if the project would:
1. Directly or indirectly cause potential substantial adverse effects, including the risk of loss,
injury, or death involving:
a. Rupture of a known earthquake fault, as delineated on the most recent Alquist -
Priolo Earthquake Fault Zoning Map issued by th e State Geologist for the area based
on other substantial evidence of as known fault. Refer to Division of Mines and
Geology Special Publication 42.
b. Strong seismic ground shaking.
c. Seismic-related ground failure, including liquefaction.
d. Landslides.
2. Result in substantial soil erosion or the loss of topsoil.
3. 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.
4. 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.
5. 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.
6. Directly or indirectly destroy a unique paleontological resource or site or unique
geologic feature.
7. 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?
8. 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?
3.5 – GEOLOGY, SOILS, AND MINERALS

3.5.4 Impacts Analysis
Impact 3.5-1. The project would not directly or indirectly cause potential substantial adverse
effects, including the risk of loss, injury, or death involving:
a) 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 based on other
substantial evidence of as known fault. (Refer to Division of Mines and Geology Special
Publication 42) (Less than Significant)
The proposed project site is not within an Alquist-Priolo Fault Rupture Hazard Zone, as designated
through the Alquist-Priolo Earthquake Fault Zoning Act, and no mapped active faults are known
to pass through the immediate project region. Therefore, the risk of ground rupture at the site is
very low. The nearest Alquist-Priolo zone encompasses traces of the Greenville fault. The
Greenville fault is mapped approximately 8 miles southwest of the proposed project site; the
Concord and Calaveras faults pass approximately 21–24 miles west and northwest of the project
site, respectively. These faults are considered capable of generating an earthquake of magnitude
6.5 to 7.0. Additionally, a seismically active blind thrust belt underlies the Coast Range–Great
Valley geomorphic boundary, and passes through the eastern portion of the County. The precise
location of the Great Valley fault system and associated blind-thrust faults are not well known
because the earthquakes on this fault system do not result in fault rupture at the ground surface.
Earthquakes associated with the Great Valley fault system include the 1983 Coalinga earthquake
and 1985 Kettleman Hills earthquake, of magnitudes 6.7 and 6.1, respectively. Additionally, two
greater than 6.0 magnitude earthquakes are believed to have occurred on the fault system in 1892
near Winters and Dixon.
The active faults may produce a range of ground shaking intensities at the project site which creates
a risk of structural damage. However, County building inspectors would review the proposed
project plans to ensure compliance with the existing and regularly amended seismic design
provisions of the 2016 CBC, in order to reduce potential impacts from seismic ground shaking,
including liquefaction. Considering there are no mapped active faults on the project site, the
potential for surface fault rupture to affect the project and pose a hazard to nearby structures or
people would be minimal. Therefore, the potential impact of the project to expose persons or
structures to risk of ground rupture along a fault line is less than significant.
b) strong seismic ground shaking; (Less than Significant)
As stated in Section 3.5.1, Existing Conditions, the project site is underlain by Pliocene Bedrock
and Older (Pleistocene) Alluvium, which according to the Safety Element, is considered to possess
“moderately low damage susceptibility” (Contra Costa County 2005a). The risk of structural
damage from ground shaking is regulated by the building codes and County Grading Ordinance.
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-15
The 2016 CBC requires uses of seismic parameters that allow structural engineering analysis for
buildings to be based on soil profiles types and proximity to known active faults. Compliance with
building and grading regulations can be expected to keep risks within generally acceptable limits,
and thus people or structures would not be exposed to potential substantial adverse effects from
seismic ground shaking. Therefore, impacts associated with the proposed project would be less
than significant.
c) seismic-related ground failure, including liquefaction; (Less than Significant)
Liquefaction potential is discussed in the Safety Element. Areas with deep water tables and those
underlain by well-consolidated ground materials typically have low or moderate liquefaction
potentials. The Safety Element identifies the project site as “generally moderate to low” (Figure
10-5 in Contra Costa County 2005a). As discussed under Section 3.5.1, geologically young and
water-saturated sandy sediments, such as those found in the extensive shoreline areas in western
and northeastern County locations and the delta, are highly susceptible to liquefaction. The project
site is underlain by primarily quaternary alluvium that is sometimes considered to be expansive.
The County provides liquefaction potential based on geologic conditions, and a review of soils
data from a number of sources (Contra Costa County 2005a).
As previously discussed, the project is required to comply with the CBC, which outlines specific
design, engineering, and development standards for structures proposed in areas with unstable
soils. Additionally, all new buildings and renovations would be subject to review and plan approval
by the County Conservation and Development Department, prior to construction. The County
building inspectors would also review project plans to ensure compliance with the seismic design
provisions of the CBC. Compliance with the current regulations would ensure that all structures
are designed and built to current standards to minimize impacts associated with seismic-related
ground failure, including liquefaction. Therefore, impacts would be less than significant.
d) landslides. (Less than Significant)
Areas at risk from landslides include areas on or close to steep hills and steep road cuts or
excavations, or areas where existing landslides have occurred. The existing topography of the site
is relatively level, as the site is used for aircraft runways, which require little to no slope. The
overall topography of the project site has a slight downward trend to the west in the northern
portion of the site and a downward trend to the east in the southern portion of the site. The County
does not recognize the project site to have landslide deposits, reclaimed areas, or filled reclaimed
areas, nor to have slope areas over 26% (Contra Costa County 2005a). The project site is underlain
by the Pliocene Bedrock and Older (Pleistocene) Alluvium, which is not considered prone to slope
failure. As such, the project site is not in an area susceptible to landslides.
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269

As previously discussed, the project is required to comply with the CBC, which outlines specific
design, engineering, and development standards for structures proposed in areas with unstable
soils. Additionally, all new buildings and renovations would be subject to review and plan approval
by the County Conservation and Development Department, prior to construction. The County
building inspectors would also review project plans to ensure compliance with the seismic design
provisions of the CBC. Compliance with the current regulations would ensure that all structures
are designed and built to current standards to minimize impacts associated with seismic-related
ground failure, including liquefaction. Therefore, impacts would be less than significant.
Impact 3.5-2. The project would not result in substantial soil erosion or the loss of topsoil.
(Less than Significant)
As discussed in Section 3.5.1.2, Site Geology, the project site is underlain by soils that are
characterized as well-drained, moderately well drained, and somewhat poorly drained soils (USDA
1977). Runoff potential of the underlying soils are characterized as, medium, slow to medium, and
slow, and the soil’s potential for erosion is slight, slight to moderate, moderate, and moderate to
low (USDA 1977). Demolition and construction activities associated with the proposed project,
including vegetation removal, excavations, and grading, would temporarily expose underlying
soils, thereby increasing the potential to cause soil erosion or the loss of topsoil. The effects of
erosion are intensified with an increase in slope (as water moves faster, it gains momentum to carry
more debris) and the narrowing of runoff channels (which increases the velocity of water).
During demolition, new construction, or renovation activities, the County would be required to
implement erosion control measures stipulated in a Stormwater Pollution Prevention Plan,
pursuant to the National Pollutant Discharge Elimination System discharge requirements (see
Section 3.8, Hydrology and Water Quality, for details regarding Stormwater Pollution Prevention
Plans). Therefore, during future demolition, new construction, and renovation activities, erosion
induced stormwater discharges would be reduced to levels that are less than significant.
Upon completion of project construction, structures, roadways, and landscaping or revegetated
areas would eventually cover any soils exposed during construction, thus minimizing the
potential for erosion -induced siltation of adjacent waterways. As a result, impacts would be
less than significant.
Impact 3.5-3. The project would not 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.
(Less than Significant)
Landslides and other ground failures occur during earthquakes when triggered by the strain
induced in soil and rock by the ground-shaking vibrations, and during non-earthquake conditions
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-17
most frequently during the rainy season. Slopes may suffer landslides, slumping, soil slips, and
rockslides. As previously discussed, the proposed project site is underlain by Pliocene Bedrock
and Older (Pleistocene) Alluvium, which possess the potential for expansive clays, hillside
earthflows and unstable cut slopes that range from soft sandstone and silty clay loam to firm. Soils
of this type, even if saturated, are too cohesive to liquefy during earthquake shaking.
Ground failure, such as lateral spreading and subsidence, occurs when stresses in the ground
exceed the resistance of earth materials to deformation or rupture. This instability can be triggered
by earthquake shaking or human-made changes, such as grading a steep slope or unstable soils.
Considering the soil types do not possess high liquefaction susceptibility and the relatively low
slope of the site, ground failure such as lateral spreading, subsidence, and liquefaction is not
deemed to be a hazard for the proposed project site. The implication of the preliminary analysis is
that the proposed project would not be located on a geologic unit or soil that is unstable potentially
resulting in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse.
In accordance with the County General Plan, further more detailed future investigations is required
for project development. The geotechnical study would be required to comply with applicable
building codes and engineering standards, including any applicable amendments to the CBC
contained in the County’s Municipal Code. The project structures would be designed to either
avoid or accommodate without issues small-scale instabilities such as shrink/swell behavior and
load-induced and long-term soil settlement, among other issues.
Impact 3.5-4. The project would 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. (Potentially Significant)
The Quaternary Alluvium underlying the project site possesses the potential for expansive clays
(Contra Costa County 2005a). Expansive soils shrink and swell as a result of moisture changes
that can cause pavements and structures founded on shallow foundations. This impact would be
potentially significant. Building damage due to volume changes associated with expansive soils
can be reduced by placing building slabs on select, granular fill and by use of rigid mat or post-
tensioned slabs. Therefore, MM-GEO-1 would require the preparation and submittal of a
geotechnical study, which would include more detailed information based on final designs that
identify soil conditions, recommend foundation designs, and provide recommendation to mitigate
for expansive soils.
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-18
Impact 3.5-5. The project may 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. (Potentially Significant)
The project site is currently serviced by a 3,000-gallon septic tank and lift station that pumps to a
leach field located southwest of the aircraft apron. Under proposed project conditions, one or a
combination of the following scenarios may occur: the existing septic tank would be expanded to
support the additional development areas on the project site, the existing septic system would be
converted to a package wastewater treatment plant, and/or the project site would connect to the
Byron Sanitary District system. Please refer to Chapter 3.14, Utilities, for additional information
on alternatives for wastewater treatment.
As previously discussed under Impact 3.5-4, the underlying soils possesses expansive potential,
which would be potentially significant. However, the project would not generally represent a
significant hazard to life or safety, and hazards would be addressed through application of modern
building codes and generally accepted professional engineering geologic principles and practice.
As stated in MM-GEO-1, prior to the approval of any building or improvement plans, a
geotechnical study would be prepared by a registered civil or geotechnical engineer, and submitted
for review and approval to the County. The geotechnical study would include more detailed
information based on final designs that identify soil conditions, recommend foundation designs,
and provide recommendation to mitigate for expansive soils. The geotechnical study would be
required to comply with applicable building codes and engineering standards, including any
applicable amendments to the CBC contained in the County’s municipal code. The project
structures would be designed to either avoid or accommodate without issues small-scale
instabilities such as shrink/swell behavior and load-induced and long-term soil settlement, among
other issues.
Impact 3.5-6. The project would not directly or indirectly destroy a unique paleontological
resource or site or unique geologic feature. (Potentially Significant)
No unique geologic features have been identified through investigation of the geology and soils
(see Section 3.5.1). Additionally, as discussed in Section 3.5.1.4, Paleontological Resources, no
paleontological records or sites have been identified on the project site. The project site contains
sedimentary units with moderate to high paleontological resources sensitivity; resources in
previously undisturbed areas may be found as shallow as 5 to 10 feet. It is possible that
paleontological resources would inadvertently be discovered during construction, which would be
potentially significant. In the event that scientifically important paleontological are unearthed
during grading activities, a paleontologist should be retained to evaluate the discovery and make a
significance determination, and if significant, make recommendations for conservation, in
accordance with MM GEO-2.
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-19
Impact 3.5-7. 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. (No Impact)
As discussed in Section 3.5.1.4, the project site is mapped by the CGS as not containing MRZs.
Therefore, there would be no significant impacts related to known mineral resources of value to
the region and the residents of the state. No impact would occur.
Impact 3.5-8. The project would not 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. (No Impact)
As discussed in Section 3.5.1.4, the project site is not located within a County-designated mineral
resource area. Therefore, there would be no significant impacts related to locally important mineral
resources. No impact would occur.
3.5.5 Mitigation Measures
The following mitigation measure would reduce potentially significant impacts to levels
below significance.
MM-GEO-1 Prior to the approval of any building or improvement plans, a geotechnical report
shall be prepared by a registered civil or geotechnical engineer and submitted to the
County Department of Conservation and Development by the applicant for that
project. The report shall address the specific approach to development. This report
shall: (A) provide specific criteria and standards for identifying suitable imported
fill materials; (B) if import fills may be expansive or corrosive, provisions shall be
made for the import of fill materials; (C) if import fills may be expansive or
corrosive, provisions shall be made for testing of soils on rough-graded pads and
providing design measures to avoid/control damage to foundations and buried
utilities; (D) provide criteria for placement of engineered fill; (E) provide further
evaluation of seismic settlement and other types of seismically induced ground
failure by recognized methods appropriate to soil conditions discovered during
subsurface investigation; (F) provide detailed evaluation of the compressibility of
the alluvial soils and forecast the anticipated amount of total settlement and timing
of settlement to occur or placing a surcharge on the site to speed settlement; (G)
provide California Building Code seismic parameters; and (H) outline
recommendations for geotechnical observation and testing services during site
preparation-, grading-and foundation-related work. Improvement, grading, and
building plans shall carry out the recommendations of the approved report.
3.5 – GEOLOGY, SOILS, AND MINERALS
Byron Airport Development Program EIR 9269
February 2022 3.5-20
MM-GEO-2 If paleontological resources (i.e., fossil bones, teeth, shells, plants, or trace fossils)
are exposed during construction activities for the project, all construction work
occurring within 100 feet of the find shall immediately stop until a qualified
paleontologist, meeting the Society of Vertebrate Paleontology standards, can
evaluate the significance of the find and determine whether or not additional study
is warranted. The paleontologist shall be empowered to temporarily stop or redirect
grading activities to allow removal of abundant or large paleontological resources.
Depending upon the significance of the find, the qualified paleontologist may
simply remove and record the find and allow work to continue. If the discovery
proves significant under the California Environmental Quality Act, additional
work, such as data recovery and extended specimen removal, may be warranted.
The qualified paleontologist shall prepare a Paleontological Resources Impact
Mitigation Program for the project, which outlines where paleontological
monitoring is required based on the location of the discovery, geotechnical reports,
and construction plans. The qualified paleontologist shall also be required to curate
specimens in a repository with permanent retrievable storage and submit a final
written report to the repository and lead agency for review.
3.5.6 Level of Significance After Mitigation
Implementation of MM-GEO-1, which requires the preparation and approval of a geotechnical
report, would reduce Impact 3.5-4 and Impact 3.5-5 to less than significant. Implementation of
MM-GEO-2 would reduce Impact 3.5-6 to less than significant.
3.5.7 Cumulative Impacts
As discussed above, the proposed project would not affect any known seismic or other geological
hazards. There may be site-specific occurrences of soil that is expansive or prone to liquefaction,
but the impact of these potential soil conditions would be reduced to less than significant with the
implementation of MM-GEO-1. There are no projects anticipated under the County General Plan
that would combine or interact with the proposed project to create a cumulative impact. Similarly,
as there are no known paleontological resources in or near the project site, the potential for
cumulative impacts would be less than significant.

3.6.1 Existing Conditions
3.6.1.1 Climate Change Overview
Climate change refers to any significant change in measures of climate, such as temperature,
precipitation, or wind patterns, lasting for an extended period of time (decades or longer). Earth’s
temperature depends on the balance between energy entering and leaving the planet’s system.
Many factors, both natural and human, can cause changes in Earth’s energy balance, including
variations in the sun's energy reaching Earth, changes in the reflectivity of Earth’s atmosphere and
surface, and changes in the greenhouse effect, which affects the amount of heat retained by Earth’s
atmosphere (EPA 2017).
The greenhouse effect is the trapping and build-up of heat in the atmosphere (troposphere) near
the Earth’s surface. The greenhouse effect traps heat in the troposphere through a threefold process
as follows: Short-wave radiation emitted by the Sun is absorbed by the Earth, the Earth emits a
portion of this energy in the form of long-wave radiation, and GHGs in the upper atmosphere
absorb this long-wave radiation and emit it into space and toward the Earth. The greenhouse effect
is a natural process that contributes to regulating Earth’s temperature and creates a pleasant, livable
environment on Earth. Human activities that emit additional GHGs to the atmosphere increase the
amount of infrared radiation that gets absorbed before escaping into space, thus enhancing the
greenhouse effect and causing the Earth’s surface temperature to rise.
The scientific record of the Earth’s climate shows that the climate system varies naturally over a
wide range of time scales and that, in general, climate changes prior to the Industrial Revolution
in the 1700s can be explained by natural causes, such as changes in solar energy, volcanic
eruptions, and natural changes in GHG concentrations. Recent climate changes, in particular the
warming observed over the past century, however, cannot be explained by natural causes alone.
Rather, it is extremely likely that human activities have been the dominant cause of that warming
since the mid-twentieth century and are the most significant driver of observed climate change
(IPCC 2013; EPA 2017). Human influence on the climate system is evident from the increasing
GHG concentrations in the atmosphere, positive radiative forcing, observed warming, and
improved understanding of the climate system (IPCC 2013). The atmospheric concentrations of
GHGs have increased to levels unprecedented in the last 800,000 years, primarily from fossil fuel
emissions and secondarily from emissions associated with land use changes (IPCC 2013).

Continued emissions of GHGs will cause further warming and changes in all components of the
climate system, which is discussed further in Section 3.6.3, Thresholds of Significance and
Methodology, below.
3.6.1.2 Greenhouse Gases
A GHG is any gas that absorbs infrared radiation in the atmosphere; in other words, GHGs trap
heat in the atmosphere. As defined in California Health and Safety Code Section 38505(g) for
purposes of administering many of the state’s primary GHG emissions reduction programs, GHGs
include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs),
perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (see also 14 CCR
15364.5).1 Some GHGs, such as CO2, CH4, and N2O, occur naturally and are emitted into the
atmosphere through natural processes and human activities. Of these gases, CO2 and CH4 are
emitted in the greatest quantities from human activities. Manufactured GHGs, which have a much
greater heat-absorption potential than CO2, include fluorinated gases, such as HFCs, PFCs, and
SF6, which are associated with certain industrial products and processes. The following paragraphs
provide a summary of the most common GHGs and their sources.2
Carbon Dioxide
CO2 is a naturally occurring gas and a byproduct of human activities and is the principal
anthropogenic GHG that affects Earth’s radiative balance. Natural sources of CO2 include
respiration of bacteria, plants, animals, and fungus; evaporation from oceans; volcanic out-gassing;
and decomposition of dead organic matter. Human activities that generate CO2 include the
combustion of fuels such as coal, oil, natural gas, and wood and changes in land use.
Methane
CH4 is produced through both natural and human activities. CH4 is a flammable gas and is the
main component of natural gas. CH4 is produced through anaerobic (without oxygen)
decomposition of waste in landfills, flooded rice fields, animal digestion, decomposition of animal
wastes, production and distribution of natural gas and petroleum, coal production, and incomplete
fossil fuel combustion.
1 Climate forcing substances include GHGs and other substances such as black carbon and aerosols. This discussion
focuses on the seven GHGs identified in the California Health and Safety Code 38505 as impacts associated with
other climate forcing substances are not evaluated herein.
2 The descriptions of GHGs are summarized from the Intergovernmental Panel on Climate Change (IPCC) Second
Assessment Report (IPCC 1995), IPCC Fourth Assessment Report (2007), California Air Resources Board’s
Glossary of Terms Used in GHG Inventories (2018a), and EPA’s Climate Change (2017).
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-3
Nitrous Oxide
N2O is produced through natural and human activities, mainly through agricultural activities and
natural biological processes, although fuel burning and other processes also create N2O. Sources
of N2O include soil cultivation practices (microbial processes in soil and water), especially the use
of commercial and organic fertilizers; manure management; industrial processes (such as in nitric
acid production, nylon production, and fossil-fuel-fired power plants); vehicle emissions; and
using N2O as a propellant (such as in rockets, racecars, and aerosol sprays).
Fluorinated Gases
Fluorinated gases are powerful synthetic GHGs emitted from many industrial processes.
Fluorinated gases are commonly used as substitutes for stratospheric ozone (O3) depleting
substances (e.g., chlorofluorocarbons [CFCs], hydrochlorofluorocarbons [HCFCs], and halons).
The most prevalent fluorinated gases include the following:
• Hydrofluorocarbons: HFCs are compounds containing only hydrogen, fluorine, and
carbon atoms. HFCs are synthetic chemicals used as alternatives to O3 depleting substances
in serving many industrial, commercial, and personal needs. HFCs are emitted as
byproducts of industrial processes and are used in manufacturing.
• Perfluorocarbons: PFCs are a group of human-made chemicals composed of carbon and
fluorine only. These chemicals were introduced as alternatives, with HFCs, to the O3
depleting substances. The two main sources of PFCs are primary aluminum production and
semiconductor manufacturing. Since PFCs have stable molecular structures and do not
break down through the chemical processes in the lower atmosphere, these chemicals have
long lifetimes, ranging between 10,000 and 50,000 years.
• Sulfur Hexafluoride: SF6 is a colorless gas soluble in alcohol and ether and slightly
soluble in water. SF6 is used for insulation in electric power transmission and distribution
equipment, semiconductor manufacturing, the magnesium industry, and as a tracer gas for
leak detection.
• Nitrogen Trifluoride: Nitrogen trifluoride is used in the manufacture of a variety of
electronics, including semiconductors and flat panel displays.
Chlorofluorocarbons
CFCs are synthetic chemicals that have been used as cleaning solvents, refrigerants, and aerosol
propellants. CFCs are chemically unreactive in the lower atmosphere (troposphere), and the
production of CFCs was prohibited in 1987 due to the chemical destruction of stratospheric O3.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-4
Hydrochlorofluorocarbons
HCFCs are a large group of compounds, whose structure is very close to that of CFCs—containing
hydrogen, fluorine, chlorine, and carbon atoms—but including one or more hydrogen atoms. Like
HFCs, HCFCs are used in refrigerants and propellants. HCFCs were also used in place of CFCs
for some applications; however, their use in general is being phased out.
Black Carbon
Black carbon is a component of fine particulate matter, which has been identified as a leading
environmental risk factor for premature death. It is produced from the incomplete combustion of
fossil fuels and biomass burning, particularly from older diesel engines and forest fires. Black
carbon warms the atmosphere by absorbing solar radiation, influences cloud formation, and
darkens the surface of snow and ice, which accelerates heat absorption and melting. Black carbon
is a short-lived substance that varies spatially, which makes it difficult to quantify the global
warming potential (GWP). Diesel particulate matter (DPM) emissions are a major source of black
carbon and are toxic air contaminants that have been regulated and controlled in California for
several decades to protect public health. In relation to declining DPM as a result of the California
Air Resources Board (CARB) regulations pertaining to diesel engines, diesel fuels, and burning
activities, CARB estimates that annual black carbon emissions in California have reduced by 70%
between 1990 and 2010, with 95% control expected by 2020 (CARB 2014).
Water Vapor
The primary source of water vapor is evaporation from the ocean, with additional vapor generated
by sublimation (change from solid to gas) from ice and snow, evaporation from other water bodies,
and transpiration from plant leaves. Water vapor is the most important, abundant, and variable
GHG in the atmosphere and maintains a climate necessary for life.
Ozone
Tropospheric O3, which is created by photochemical reactions involving gases from both natural
sources and human activities, acts as a GHG. Stratospheric O3, which is created by the interaction
between solar ultraviolet radiation and molecular oxygen, plays a decisive role in the stratospheric
radiative balance. Depletion of stratospheric O3, due to chemical reactions that may be enhanced
by climate change, results in an increased ground-level flux of ultraviolet-B radiation.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-5
Aerosols
Aerosols are suspensions of particulate matter in a gas emitted into the air through burning biomass
(plant material) and fossil fuels. Aerosols can warm the atmosphere by absorbing and emitting
heat and can cool the atmosphere by reflecting light.
3.6.1.3 Global Warming Potential
Gases in the atmosphere can contribute to climate change both directly and indirectly. Direct
effects occur when the gas itself absorbs radiation. Indirect radiative forcing occurs when chemical
transformations of the substance produce other GHGs, when a gas influences the atmospheric
lifetimes of other gases, and/or when a gas affects atmospheric processes that alter the radiative
balance of the Earth (e.g., affect cloud formation or albedo) (EPA 2017). The Intergovernmental
Panel on Climate Change developed the GWP concept to compare the ability of each GHG to trap
heat in the atmosphere relative to another gas. The GWP of a GHG is defined as the ratio of the
time-integrated radiative forcing from the instantaneous release of 1 kilogram of a trace substance
relative to that of 1 kilogram of a reference gas (IPCC 2014). The reference gas used is CO2;
therefore, GWP-weighted emissions are measured in metric tons (MT) of CO2 equivalent (CO2e).
The California Emissions Estimator Model (CalEEMod), Version 2016.3.2, assumes that the GWP
for CH4 is 25 (so emissions of 1 MT of CH4 are equivalent to emissions of 25 MT of CO2), and
the GWP for N2O is 298, based on the Intergovernmental Panel on Climate Change Fourth
Assessment Report (IPCC 2007).
3.6.1.4 Greenhouse Gas Inventories and Climate Change Conditions
Global Inventory
Anthropogenic GHG emissions worldwide in 2016 (the most recent year for which data is
available) totaled approximately 49,300 million metric tons (MMT) of CO2e, excluding land use
change and forestry (PBL 2017). Six countries—China, the United States, the Russian
Federation, India, Japan, and Brazil—and the European community accounted for approximately
65% of the total global emissions, or approximately 32,255 MMT CO2e (PBL 2017). Table 3.6-1
presents the top GHG-emissions-producing countries.

National and State Inventories
Per the U.S. Environmental Protection Agency (EPA) Inventory of U.S. Greenhouse Gas Emissions
and Sinks: 1990–2016 (EPA 2018), total United States GHG emissions were approximately 6,511.3
MMT CO2e in 2016. The primary GHG emitted by human activities in the United States was CO2,
which represented approximately 81.6% of total GHG emissions (5,310.9 MMT CO2e). The largest
source of CO2, and of overall GHG emissions, was fossil-fuel combustion, which accounted for
approximately 93.5% of CO2 emissions in 2016 (4,966.0 MMT CO2e). Relative to 1990, gross United
States GHG emissions in 2016 are higher by 2.4%; down from a high of 15.7% above 1990 levels in
2007. GHG emissions decreased from 2015 to 2016 by 1.9% (126.8 MMT CO2e) and overall, net
emissions in 2016 were 11.1% below 2005 levels (EPA 2018).
According to California’s 2000–2016 GHG emissions inventory (2018 edition), California emitted
429.4 MMT CO2e in 2016, including emissions resulting from out-of-state electrical generation
(CARB 2018b). The sources of GHG emissions in California include transportation, industrial
uses, electric power production from both in-state and out-of-state sources, commercial and
residential uses, agriculture, high GWP substances, and recycling and waste. The California GHG
emission source categories (as defined in CARB’s 2008 Scoping Plan) and their relative
contributions in 2016 are presented in Table 3.6-2.

a Percentage of total has been rounded and total may not sum due to rounding.
b The Aliso Canyon natural gas leak event released 1.96 MMT CO2e of unanticipated emissions in 2015 and 0.53 MMT CO2e in 2016. These
leak emissions will be fully mitigated according to legal settlement and are tracked separately from routine inventory emissions.
c Includes emissions associated with imported electricity, which account for 26.28 MMT CO2e.
Between 2000 and 2016, per capita GHG emissions in California have dropped from a peak of
14.0 MT per person in 2001 to 10.8 MT per person in 2016, representing a 23% decrease. In
addition, total GHG emissions in 2016 were approximately 12 MMT CO2e less than 2015
emissions. The declining trend in GHG emissions, coupled with programs that will continue to
provide additional GHG reductions going forward, demonstrates that California will continue to
reduce emissions below the 2020 target of 431 MT CO2e (CARB 2018b).
Contra Costa County Inventory
Total GHG emissions for the unincorporated areas of Contra Costa County (County) in 2005 and
2013 were estimated at approximately 1,403,610 MT CO2e and 1,392,450 MT CO2e, respectively.
The 2013 inventory represents the most recent year of data, with the transportation sector as the
primary contributor, generating 47% of GHG emissions. Other sources (with percentage of total
GHG emissions) include residential energy (19%), landfills (14%), nonresidential energy (9%),
off-road equipment (5%), agriculture (4%), solid waste (2%), water and wastewater (1%), and Bay
Area Rapid Transit (less than 1%) (Contra Costa County 2015).
Potential Effects of Climate Change
Globally, climate change has the potential to affect numerous environmental resources through
uncertain impacts related to future air temperatures and precipitation patterns. The 2014
Intergovernmental Panel on Climate Change Synthesis Report (IPCC 2014) indicated that
warming of the climate system is unequivocal, and since the 1950s, many of the observed changes
are unprecedented over decades to millennia. Signs that global climate change has occurred
include warming of the atmosphere and ocean, diminished amounts of snow and ice, and rising
sea levels (IPCC 2014).
In California, climate change impacts have the potential to affect sea level rise, agriculture,
snowpack and water supply, forestry, wildfire risk, public health, and electricity demand and
supply (CCCC 2006). The primary effect of global climate change has been a 0.2°C rise in average
global tropospheric temperature per decade, determined from meteorological measurements
worldwide between 1990 and 2005. Scientific modeling predicts that continued emissions of
GHGs at or above current rates would induce more extreme climate changes during the twenty-
first century than were observed during the twentieth century. A warming of about 0.2°C (0.36°F)
per decade is projected, and there are identifiable signs that global warming could be taking place.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-8
Although climate change is driven by global atmospheric conditions, climate change impacts are
felt locally. A scientific consensus confirms that climate change is already affecting California.
The average temperatures in California have increased, leading to more extreme hot days and
fewer cold nights. Shifts in the water cycle have been observed, with less winter precipitation
falling as snow, and both snowmelt and rainwater running off earlier in the year. Sea levels have
risen, and wildland fires are becoming more frequent and intense due to dry seasons that start
earlier and end later (CAT 2010).
An increase in annual average temperature is a reasonably foreseeable effect of climate change.
Observed changes over the last several decades across the western United States reveal clear
signals of climate change. Statewide average temperatures increased by about 1.7°F from 1895 to
2011, and warming has been greatest in the Sierra Nevada (CCCC 2012). By 2050, California is
projected to warm by approximately 2.7°F above 2000 averages, a threefold increase in the rate of
warming over the last century. By 2100, average temperatures could increase by 4.1°F to 8.6°F,
depending on emissions levels. Springtime warming—a critical influence on snowmelt—will be
particularly pronounced. Summer temperatures will rise more than winter temperatures, and the
increases will be greater in inland California, compared to the coast. Heat waves will be more
frequent, hotter, and longer. There will be fewer extremely cold nights (CCCC 2012). A de cline
of Sierra Nevada snowpack, which accounts for approximately half of the surface water storage in
California, by 30% to as much as 90% is predicted over the next 100 years (CAT 2006).
Model projections for precipitation over California continue to show the Mediterranean pattern of
wet winters and dry summers with seasonal, year-to-year, and decade-to-decade variability. For
the first time, however, several of the improved climate models shift toward drier conditions by
the mid-to-late twenty-first century in central, and most notably, Southern California. By the late
century, all projections show drying, and half of them suggest 30-year average precipitation will
decline by more than 10% below the historical average (CCCC 2012).
A summary of current and future climate change impacts to resource areas in California, as
discussed in Safeguarding California: Reducing Climate Risk (CNRA 2014), is provided below.
Agriculture
Some of the specific challenges faced by the agricultural sector and farmers include more drastic
and unpredictable precipitation and weather patterns; extreme weather events that range from
severe flooding to extreme drought and destructive storm events; significant shifts in water
availably and water quality; changes in pollinator lifecycles; temperature fluctuations, including
extreme heat stress and decreased chill hours; increased risks from invasive species, weeds,
agricultural pests, and plant diseases; and disruptions to the transportation and energy
infrastructure supporting agricultural production.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-9
Biodiversity and Habitat
Specific climate change challenges to biodiversity and habitat include species migration in
response to climatic changes; range shift and novel combinations of species; pathogens, parasites
and disease; invasive species; extinction risks; changes in the timing of seasonal life-cycle events;
food web disruptions; and threshold effects (i.e., a change in the ecosystem that results in a “tipping
point” beyond which irreversible damage or loss has occurs).
Energy
Specific climate change challenges for the energy sector include temperature, fluctuating
precipitation patterns, increasing extreme weather events, and sea level rise.
Forestry
The most significant climate change related risk to forests is accelerated risk of wildfire and more
frequent and severe droughts. Droughts have resulted in more large scale mortalities and,
combined with increasing temperatures, have led to an overall increase in wildfire risks. Increased
wildfire intensity subsequently increases public safety risks, property damage, fire suppression and
emergency response costs, watershed and water quality impacts, and vegetation conversions.
Ocean and Coastal Ecosystems and Resources
Sea level rise, changing ocean conditions and other climate change stressors are likely to
exacerbate long-standing challenges related to ocean and coastal ecosystems in addition to
threatening people and infrastructure located along the California coastline and in coastal
communities. Sea level rise in addition to more frequent and severe coastal storms and erosion are
threatening vital infrastructure such as roads, bridges, power plants, ports and airports, gasoline
pipes, and emergency facilities as well as negatively impacting the coastal recreational assets such
as beaches and tidal wetlands.
Public Health
Climate change can impact public health through various environmental changes and is the largest
threat to human health in the twenty-first century. Changes in precipitation patterns affect public health
primarily through potential for altered water supplies and extreme events such as heat, floods, droughts,
and wildfires. Increased frequency, intensity, and duration of extreme heat and heat waves are likely
to increase the risk of mortality due to heat-related illness as well as exacerbate existing chronic health
conditions. Other extreme weather events are likely to negatively impact air quality and increase or
intensify respiratory illness such as asthma and allergies.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-10
Transportation
While the transportation industry is a source of GHG emissions, it is also vulnerable to climate
change risks. Increasing temperatures and extended periods of extreme heat threaten the integrity
of the roadways and rail lines. High temperatures cause the road surfaces to expand which leads
to increased pressure and pavement buckling. High temperatures can also cause rail breakages,
which could lead to train derailment. Other forms of extreme weather events, such as extreme
storm events, can negatively impact infrastructure, which can impair movement of peoples and
goods, or potentially block evacuation routes and emergency access roads. Increased wildfires,
flooding, erosion risks, landslides, mudslides, and rockslides can all profoundly impact the
transportation system and pose a serious risk to public safety.
Water
Climate change could seriously impact the timing, form, amount of precipitation, runoff patterns,
and frequency and severity of precipitation events. Higher temperatures reduce the amount of
snowpack and lead to earlier snowmelt, which can impact water supply availability, natural
ecosystems, and winter recreation. Water supply availability during the intense dry summer
months is heavily dependent on the snowpack accumulated during the winter time. Increased risk
of flooding has a variety of public health concerns including water quality, public safety, property
damage, displacement, and post-disaster mental health problems. Prolonged and intensified
droughts can also negatively affect groundwater reserves and result in increased overdraft and
subsidence. The higher risk of wildfires can lead to increased erosion, which can negatively impact
watersheds and result in poor water quality.
In March 2016, the California Natural Resources Agency (CNRA) released Safeguarding
California: Implementation Action Plans, a document that shows how California is acting to
convert the recommendations contained in the 2014 Safeguarding California plan into action
(CNRA 2016). Additionally, the CNRA released Safeguarding California Plan: 2018 Update in
January 2018, which provides a roadmap for state agencies to protect communities, infrastructure,
services, and the natural environment from climate change impacts. The 2018 Safeguarding
California Plan includes 69 recommendations across 11 sectors and more than 1,000 on-going
actions and next steps developed by scientific and policy experts across 38 state agencies (CNRA
2018). As with previous state adaptation plans, the 2018 Update addresses the following:
acceleration of warming across the state, more intense and frequent heat waves, greater riverine
flows, accelerating sea level rise, more intense and frequent drought, more severe and frequent
wildfires, more severe storms and extreme weather events, shrinking snowpack and less overall
precipitation, and ocean acidification, hypoxia, and warming.

3.6.2 Relevant Plans, Policies, and Ordinances
Federal
Massachusetts v. EPA
In Massachusetts v. EPA (April 2007), the U.S. Supreme Court directed the EPA administrator
to determine whether GHG emissions from new motor vehicles cause or contribute to air
pollution that may reasonably be anticipated to endanger public health or welfare, or whether
the science is too uncertain to make a reasoned decision. In D ecember 2009, the administrator
signed a final rule with the following two distinct findings regarding GHGs under Section
202(a) of the federal Clean Air Act:
• The Administrator found that elevated concentrations of GHGs—CO2, CH4, N2O, HFCs,
PFCs, and SF6—in the atmosphere threaten the public health and welfare of current and
future generations. This is the “endangerment finding.”
• The Administrator further found the combined emissions of GHGs—CO2, CH4, N2O, and
HFCs—from new motor vehicles and new motor vehicle engines contribute to the GHG air
pollution that endangers public health and welfare. This is the “cause or contribute finding.”
These two findings were necessary to establish the foundation for regulation of GHGs from new
motor vehicles as air pollutants under the Clean Air Act.
Energy Independence and Security Act of 2007
The Energy Independence and Security Act of 2007 (December 2007), among other key measures,
would do the following, which would aid in the reduction of national GHG emissions:
• Increase the supply of alternative fuel sources by setting a mandatory Renewable Fuel
Standard requiring fuel producers to use at least 36 billion gallons of biofuel in 2022.
• Set a target of 35 miles per gallon for the combined fleet of cars and light trucks by model
year 2020, and direct National Highway Traffic Safety Administration (NHTSA) to
establish a fuel economy program for medium- and heavy-duty trucks and create a separate
fuel economy standard for work trucks.
• Prescribe or revise standards affecting regional efficiency for heating and cooling products
and procedures for new or amended standards, energy conservation, energy-efficiency
labeling for consumer electronic products, residential boiler efficiency, electric motor
efficiency, and home appliances.

Byron Airport Development Program EIR 9269
February 2022 3.6-12
Federal Vehicle Standards
In 2007, in response to the Massachusetts v. EPA U.S. Supreme Court ruling, the Bush
administration issued Executive Order (EO) 13432 directing the EPA, the Department of
Transportation, and the Department of Energy to establish regulations that reduce GHG emissions
from motor vehicles, non-road vehicles, and non-road engines by 2008. In 2009, the NHTSA
issued a final rule regulating fuel efficiency and GHG emissions from cars and light-duty trucks
for model year 2011, and in 2010, the EPA and NHTSA issued a final rule regulating cars and
light-duty trucks for model years 2012–2016 (75 FR 25324–25728).
In 2010, President Obama issued a memorandum directing the Department of Transportation,
Department of Energy, EPA, and NHTSA to establish additional standards regarding fuel
efficiency and GHG reduction, clean fuels, and advanced vehicle infrastructure. In response to this
directive, the EPA and NHTSA proposed stringent, coordinated federal GHG and fuel economy
standards for model years 2017–2025 light-duty vehicles. The proposed standards projected to
achieve 163 grams/mile of CO2 in model year 2025, on an average industry fleet-wide basis, which
is equivalent to 54.5 miles per gallon if this level were achieved solely through fuel efficiency.
The final rule was adopted in 2012 for model years 2017–2021 (77 FR 62624–63200), and NHTSA
intends to set standards for model years 2022–2025 in a future rulemaking.
In addition to the regulations applicable to cars and light-duty trucks described above, in 2011, the
EPA and NHTSA announced fuel economy and GHG standards for medium- and heavy-duty trucks
for model years 2014–2018. The standards for CO2 emissions and fuel consumption are tailored to
three main vehicle categories: combination tractors, heavy-duty pickup trucks and vans, and vocational
vehicles. According to the EPA, this regulatory program will reduce GHG emissions and fuel
consumption for the affected vehicles by 6%–23% over the 2010 baselines (76 FR 57106–57513).
In August 2016, the EPA and NHTSA announced the adoption of the phase two program related
to the fuel economy and GHG standards for medium- and heavy-duty trucks. The phase two
program will apply to vehicles with model year 2018 through 2027 for certain trailers, and model
years 2021 through 2027 for semi-trucks, large pickup trucks, vans, and all types of sizes of buses
and work trucks. The final standards are expected to lower CO2 emissions by approximately 1.1
billion MT and reduce oil consumption by up to 2 billion barrels over the lifetime of the vehicles
sold under the program (EPA and NHTSA 2016).
State
The statewide GHG emissions regulatory framework is summarized below by category: state
climate change targets, building energy, renewable energy and energy procurement, mobile
sources, solid waste, water, and other state regulations and goals. The following text describes
EOs, Assembly Bills (ABs), Senate Bills (SBs), and other plans and policies that would directly
or indirectly reduce GHG emissions and/or address climate change issues.

State Climate Change Targets
The state has taken a number of actions to address climate change. These include EOs, legislation,
and CARB plans and requirements. These are summarized below.
Executive Order S-3-05
EO S-3-05 (June 2005) established California’s GHG emissions reduction targets and laid out
responsibilities among the state agencies for implementing the EO and for reporting on progress
toward the targets. This EO established the following targets:
• By 2010, reduce GHG emissions to 2000 levels
• By 2020, reduce GHG emissions to 1990 levels
• By 2050, reduce GHG emissions to 80% below 1990 levels
EO S-3-05 also directed the California Environmental Protection Agency to report biannually on
progress made toward meeting the GHG targets and the impacts to California due to global
warming, including impacts to water supply, public health, agriculture, the coastline, and forestry.
The Climate Action Team was formed, which subsequently issued reports from 2006 to 2010.
Assembly Bill 32
In furtherance of the goals established in EO S-3-05, the legislature enacted AB 32. The bill is
referred to as the California Global Warming Solutions Act of 2006 (September 2006). AB 32
provided initial direction on creating a comprehensive multiyear program to limit California’s
GHG emissions at 1990 levels by 2020 and initiate the transformations required to achieve the
state’s long-range climate objectives.
Senate Bill 32 and Assembly Bill 197
SB 32 and AB 197 (enacted in 2016) are companion bills. SB 32 codified the 2030 emissions
reduction goal of EO B-30-15 by requiring CARB to ensure that statewide GHG emissions are
reduced to 40% below 1990 levels by 2030. AB 197 established the Joint Legislative Committee
on Climate Change Policies, consisting of at least three members of the senate and three members
of the assembly, in order to provide on-going oversight over implementation of the state’s climate
policies. AB 197 also added two members of the legislature to the state board as nonvoting
members; requires CARB to make available and update (at least annually via its website)
emissions data for GHGs, criteria air pollutants, and toxic air contaminants from reporting
facilities; and requires CARB to identify specific information for GHG emissions reduction
measures when updating the scoping plan.

California Air Resources Board’s 2007 Statewide Limit
In 2007, in accordance with California Health and Safety Code, Section 38550, CARB approved
a statewide limit on the GHG emissions level for year 2020 consistent with the determined 1990
baseline (427 MMT CO2e).
California Air Resources Board’s Climate Change Scoping Plan
One specific requirement of AB 32 is for CARB to prepare a scoping plan for achieving the
maximum technologically feasible and cost-effective GHG emission reductions by 2020
(California Health and Safety Code, Section 38561[a]), and to update the plan at least once every
5 years. In 2008, CARB approved the first scoping plan. The Climate Change Proposed Scoping
Plan: A Framework for Change (Scoping Plan) included a mix of recommended strategies that
combined direct regulations, market-based approaches, voluntary measures, policies, and other
emission reduction programs calculated to meet the 2020 statewide GHG emission limit and
initiate the transformations needed to achieve the state’s long-range climate objectives. The key
elements of the Scoping Plan include the following (CARB 2008):
1. Expanding and strengthening existing energy efficiency programs as well as building and
appliance standards
2. Achieving a statewide renewables energy mix of 33%
3. Developing a California cap-and-trade program that links with other Western Climate
Initiative partner programs to create a regional market system and caps sources
contributing 85% of California’s GHG emissions
4. Establishing targets for transportation-related GHG emissions for regions throughout
California, and pursuing policies and incentives to achieve those targets
5. Adopting and implementing measures pursuant to existing state laws and policies,
including California’s clean car standards, goods movement measures, and the Low Carbon
Fuel Standard (LCFS) (17 CCR Section 95480 et seq.)
6. Creating targeted fees, including a public goods charge on water use, fees on high GWP
gases, and a fee to fund the administrative costs of the State of California’s long-term
commitment to AB 32 implementation
The Scoping Plan also identified local governments as essential partners in achieving California’s
goals to reduce GHG emissions because they have broad influence and, in some cases, exclusive
authority over activities that contribute to significant direct and indirect GHG emissions through
their planning and permitting processes, local ordinances, outreach and education efforts, and
municipal operations. Specifically, the Scoping Plan encouraged local governments to adopt a
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-15
reduction goal for municipal operations and for community emissions to reduce GHGs by
approximately 15% from then levels (2008) by 2020. Many local governments developed
community-scale local GHG reduction plans based on this Scoping Plan recommendation.
In 2014, CARB approved the first update to the Scoping Plan. The First Update to the Climate
Change Scoping Plan: Building on the Framework (First Update) defined the state’s GHG
emission reduction priorities for the next 5 years and laid the groundwork to start the transition to
the post-2020 goals set forth in EOs S-3-05 and B-16-2012 (CARB 2014). The First Update
concluded that California is on track to meet the 2020 target but recommended a 2030 mid-term
GHG reduction target be established to ensure a continuum of action to reduce emissions. The
First Update recommended a mix of technologies in key economic sectors to reduce emissions
through 2050, including energy demand reduction through efficiency and activity changes; large-
scale electrification of on-road vehicles, buildings, and industrial machinery; decarbonizing
electricity and fuel supplies; and the rapid market penetration of efficient and clean energy
technologies. As part of the First Update, CARB recalculated the state’s 1990 emissions level,
using more recent GWPs identified by the Intergovernmental Panel on Climate Change, from 427
MMT CO2e to 431 MMT CO2e.
In 2015, as directed by EO B-30-15, CARB began working on an update to the Scoping Plan to
incorporate the 2030 target of 40% below 1990 levels by 2030 to keep California on its trajectory
toward meeting or exceeding the long-term goal of reducing GHG emissions to 80% below 1990
levels by 2050 as set forth in S-3-05. The governor called on California to pursue a new and
ambitious set of strategies, in line with the five climate change pillars from his inaugural address,
to reduce GHG emissions and prepare for the unavoidable impacts of climate change. In summer
2016, the legislature affirmed the importance of addressing climate change through passage of SB
32 (Pavley, Chapter 249, Statutes of 2016).
In January 2017, CARB released the 2017 Climate Change Scoping Plan Update (Second Update)
for public review and comment (CARB 2017a). The Second Update builds on the successful
framework established in the initial Scoping Plan and First Update, while identifying new,
technologically feasible and cost-effective strategies that will serve as the framework to achieve
the 2030 GHG target and define the state’s climate change priorities to 2030 and beyond. The
strategies’ known commitments include implementing renewable energy and energy efficiency
(including the mandates of SB 350), increased stringency of the LCFS, measures identified in the
Mobile Source and Freight Strategies, measures identified in the proposed Short-Lived Climate
Pollutant Plan, and increased stringency of SB 375 targets. To fill the gap in additional reductions
needed to achieve the 2030 target, it recommends continuing the cap-and-trade program and a
measure to reduce GHGs from refineries by 20%.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-16
For local governments, the Second Update replaced the initial Scoping Plan’s 15% reduction goal
with a recommendation to aim for a community-wide goal of no more than 6 MT CO2e per capita
by 2030 and no more than 2 MT CO2e per capita by 2050, which are developed around the
scientifically based levels necessary to limit global warming below 2℃. The Second Update
recognized the benefits of local government GHG planning (e.g., through climate action plans
[CAPs]) and provided more information regarding tools CARB is working on to support those
efforts. It also recognizes the California Environmental Quality Act (CEQA) streamlining
provisions for project-level review where there is a legally adequate CAP. The Second Update was
approved by CARB’s Governing Board on December 14, 2017.
The Scoping Plan recommends strategies for implementation at the statewide level to meet the
goals of AB 32, SB 32, and the EOs and establishes an overall framework for the measures that
will be adopted to reduce California’s GHG emissions. A project is considered consistent with the
statutes and EOs if it meets the general policies in reducing GHG emissions in order to facilitate
the achievement of the state’s goals and does not impede attainment of those goals. As discussed
in several cases, a given project need not be in perfect conformity with each and every planning
policy or goal to be consistent. A project would be consistent if it would further the objectives and
not obstruct their attainment.
California Air Resources Board’s Regulations for the Mandatory Reporting of Greenhouse
Gas Emissions
CARB’s Regulation for the Mandatory Reporting of Greenhouse Gas Emissions (17 CCR 95100–
95157) incorporated by reference certain requirements that EPA promulgated in its Final Rule on
Mandatory Reporting of Greenhouse Gases (Title 40, CFR Part 98). Specifically, Section 95100(c)
of the Mandatory Reporting Regulation incorporated those requirements that EPA promulgated in
the Federal Register on October 30, 2009; July 12, 2010; September 22, 2010; October 28, 2010;
November 30, 2010; December 17, 2010; and April 25, 2011. In general, entities subject to the
Mandatory Reporting Regulation that emit over 10,000 MT CO2e per year are required to report
annual GHGs through the California Electronic GHG Reporting Tool. Certain sectors, such as
refineries and cement plants, are required to report regardless of emission levels. Entities that emit
more than the 25,000 MT CO2e per year threshold are required to have their GHG emission report
verified by a CARB-accredited third-party.
Executive Order B-18-12
EO B-18-12 (April 2012) directed state agencies, departments, and other entities under the
governor’s executive authority to take action to reduce entity-wide GHG emissions by at least 10%
by 2015 and 20% by 2020, as measured against a 2010 baseline. EO B-18-12 also established
goals for existing state buildings for reducing grid-based energy purchases and water use.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-17
Executive Order B-30-15
EO B-30-15 (April 2015) identified an interim GHG reduction target in support of targets
previously identified under S-3-05 and AB 32. EO B-30-15 set an interim target goal of reducing
GHG emissions to 40% below 1990 levels by 2030 to keep California on its trajectory toward
meeting or exceeding the long-term goal of reducing GHG emissions to 80% below 1990 levels
by 2050 as set forth in S-3-05. To facilitate achieving this goal, EO B-30-15 called for CARB to
update the Scoping Plan to express the 2030 target in terms of MMT CO2e. The EO also called for
state agencies to continue to develop and implement GHG emission reduction programs in support
of the reduction targets.
Senate Bill 605 and Senate Bill 1383
SB 605 (2014) requires CARB to complete a comprehensive strategy to reduce emissions of short-
lived climate pollutants in the state, and SB 1383 (2016) requires CARB to approve and implement
that strategy by January 1, 2018. SB 1383 also establishes specific targets for the reduction of
short-lived climate pollutants (40% below 2013 levels by 2030 for CH4 and HFCs, and 50% below
2013 levels by 2030 for anthropogenic black carbon), and provides direction for reductions from
dairy and livestock operations and landfills. Accordingly, and as mentioned above, CARB adopted
its Short-Lived Climate Pollutant Reduction Strategy in March 2017. The Short-Lived Climate
Pollutant Reduction Strategy establishes a framework for the statewide reduction of emissions of
black carbon, CH4, and fluorinated gases (CARB 2017b).
Building Energy
Title 24, Part 6
Title 24 of the California Code of Regulations was established in 1978 and serves to enhance and
regulate California’s building standards. While not initially promulgated to reduce GHG
emissions, Part 6 of Title 24 specifically established Building Energy Efficiency Standards that
are designed to ensure new and existing buildings in California achieve energy efficiency and
preserve outdoor and indoor environmental quality. These energy efficiency standards are
reviewed every few years by the Building Standards Commission and the California Energy
Commission (CEC) (and revised if necessary) (California Public Resources Code [PRC], Section
25402[b][1]). The regulations receive input from members of industry, as well as the public, in
order to “reduce the wasteful, uneconomic, inefficient, or unnecessary consumption of energy”
(California PRC, Section 25402). These regulations are carefully scrutinized and analyzed for
technological and economic feasibility (California PRC, Section 25402[d]) and cost effectiveness
(California PRC, Sections 25402[b][2] and [b][3]). As a result, these standards save energy,
increase electricity supply reliability, increase indoor comfort, avoid the need to construct new
power plants, and help preserve the environment. The current Title 24 standards are the 2019 Title
24 building energy efficiency standards, which became effective January 1, 2020.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-18
Title 24, Part 11
In addition to the CEC’s efforts, in 2008, the California Building Standards Commission adopted
the nation’s first green building standards. The California Green Building Standards Code (Part 11
of Title 24) is commonly referred to as CALGreen, and establishes minimum mandatory standards
as well as voluntary standards pertaining to the planning and design of sustainable site
development, energy efficiency (in excess of the California Energy Code requirements), water
conservation, material conservation, and interior air quality. The CALGreen standards took effect
in January 2011 and instituted mandatory minimum environmental performance standards for all
ground-up, new construction of commercial, low-rise residential and state-owned buildings and
schools and hospitals. The 2019 CALGreen standards are the current applicable standards. For
nonresidential projects, some of the key mandatory CALGreen 2019 standards involve
requirements related to bicycle parking, designated parking for clean air vehicles, electric vehicle
(EV) charging stations, shade trees, water conserving plumbing fixtures and fittings, outdoor
potable water use in landscaped areas, recycled water supply systems, construction waste
management, excavated soil and land clearing debris, and commissioning (24 CCR Part 11).
Title 20
Title 20 of the California Code of Regulations requires manufacturers of appliances to meet state
and federal standards for energy and water efficiency. The CEC certifies an appliance based on a
manufacturer’s demonstration that the appliance meets the standards. New appliances regulated
under Title 20 include refrigerators, refrigerator-freezers, and freezers; room air conditioners and
room air-conditioning heat pumps; central air conditioners; spot air conditioners; vented gas space
heaters; gas pool heaters; plumbing fittings and plumbing fixtures; fluorescent lamp ballasts;
lamps; emergency lighting; traffic signal modules; dishwaters; clothes washers and dryers;
cooking products; electric motors; low voltage dry-type distribution transformers; power supplies;
televisions and consumer audio and video equipment; and battery charger systems. Title 20
presents protocols for testing each type of appliance covered under the regulations and appliances
must meet the standards for energy performance, energy design, water performance, and water
design. Title 20 contains three types of standards for appliances: federal and state standards for
federally regulated appliances, state standards for federally regulated appliances, and state
standards for non-federally regulated appliances.
Senate Bill 1
SB 1 (August 2006) established a $3 billion rebate program to support the goal of the state to
install rooftop solar energy systems with a generation capacity of 3,000 megawatts through 2016.
SB 1 added sections to the PRC, including Chapter 8.8 (California Solar Initiative), that require
building projects applying for ratepayer-funded incentives for photovoltaic systems to meet
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-19
minimum energy efficiency levels and performance requirements. Section 25780 established that
it is a goal of the state to establish a self-sufficient solar industry. The goals included establishing
solar energy systems as a viable mainstream option for both homes and businesses within 10 years
of adoption, and placing solar energy systems on 50% of new homes within 13 years of adoption.
SB 1, also termed Go Solar California, was previously titled Million Solar Roofs.
Assembly Bill 1470 (Solar Water Heating)
This bill established the Solar Water Heating and Efficiency Act of 2007. The bill makes findings
and declarations of the legislature relating to the promotion of solar water heating systems and
other technologies that reduce natural gas demand.
Renewable Energy and Energy Procurement
Senate Bill 1078
SB 1078 (September 2002) established the Renewables Portfolio Standard program, which required
an annual increase in renewable generation by the utilities equivalent to at least 1% of sales, with an
aggregate goal of 20% by 2017. This goal was subsequently accelerated, requiring utilities to obtain
20% of their power from renewable sources by 2010 (see SB 107, EO S-14-08, and S-21-09).
Senate Bill 1368
SB 1368 (September 2006) required the CEC to develop and adopt regulations for GHG emission
performance standards for the long-term procurement of electricity by local publicly owned
utilities. These standards must be consistent with the standards adopted by the California Public
Utilities Commission (CPUC).
Assembly Bill 1109
Enacted in 2007, AB 1109 required the CEC to adopt minimum energy efficiency standards for
general-purpose lighting and to reduce electricity consumption 50% for indoor residential lighting
and 25% for indoor commercial lighting.
Executive Order S-14-08
EO S-14-08 (November 2008) focused on the contribution of renewable energy sources to meet
the electrical needs of California while reducing the GHG emissions from the electrical sector.
This EO required that all retail suppliers of electricity in California serve 33% of their load with
renewable energy by 2020. Furthermore, the EO directed state agencies to take appropriate actions
to facilitate reaching this target. The CNRA, through collaboration with CEC and the California
Department of Fish and Wildlife (formerly the California Department of Fish and Game), was
directed to lead this effort.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-20
Executive Order S-21-09 and Senate Bill X1-2
EO S-21-09 (September 2009) directed CARB to adopt a regulation consistent with the goal of
EO S-14-08 by July 31, 2010. CARB was further directed to work with CPUC and CEC to ensure
that the regulation built upon the Renewables Portfolio Standard program and was applicable to
investor-owned utilities, publicly owned utilities, direct access providers, and community choice
providers. Under this order, CARB was to give the highest priority to those renewable resources
that provide the greatest environmental benefits with the least environmental costs and impacts on
public health and can be developed the most quickly in support of reliable, efficient, cost-effective
electricity system operations. On September 23, 2010, CARB initially approved regulations to
implement a Renewable Electricity Standard. However, this regulation was not finalized because
of subsequent legislation (SB X1-2) signed by Governor Brown in April 2011.
SB X1-2 expanded the Renewables Portfolio Standard by establishing a renewable energy target
of 20% of the total electricity sold to retail customers in California per year by December 31, 2013,
and 33% by December 31, 2020, and in subsequent years. Under the bill, a renewable electrical
generation facility is one that uses biomass, solar thermal, photovoltaic, wind, geothermal, fuel
cells using renewable fuels, small hydroelectric generation (30 megawatts or less), digester gas,
municipal solid waste conversion, landfill gas, ocean wave, ocean thermal, or tidal current, and
that meets other specified requirements with respect to its location.
SB X1-2 applies to all electricity retailers in the state, including publicly owned utilities, investor-
owned utilities, electricity service providers, and community choice aggregators. All of these
entities must meet the renewable energy goals listed above.
Senate Bill 350
SB 350 (October 2015) further expanded the Renewables Portfolio Standard by establishing a goal
of 50% of the total electricity sold to retail customers in California per year by December 31, 2030.
In addition, SB 350 included the goal to double the energy efficiency savings in electricity and
natural gas final end uses (such as heating, cooling, lighting, or class of energy uses on which an
energy-efficiency program is focused) of retail customers through energy conservation and
efficiency. The bill also requires the CPUC, in consultation with the CEC, to establish efficiency
targets for electrical and gas corporations consistent with this goal.
Senate Bill 100
SB 100 (2018) increased the standards set forth in SB 350 establishing that 44% of the total
electricity sold to retail customers in California per year by December 31, 2024, 52% by December
31, 2027, and 60% by December 31, 2030, be secured from qualifying renewable energy sources.
SB 100 states that it is the policy of the state that eligible renewable energy resources and zero -
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-21
carbon resources supply 100% of the retail sales of electricity to California. This bill requires that
the achievement of 100% zero-carbon electricity resources does not increase the carbon emissions
elsewhere in the western grid and that the achievement not be achieved through resource shuffling.
Mobile Sources
Assembly Bill 1493
AB 1493 (July 2002) was enacted in response to the transportation sector accounting for more than
half of California’s CO2 emissions. AB 1493 required CARB to set GHG emission standards for
passenger vehicles, light-duty trucks, and other vehicles determined by the state board to be
vehicles that are primarily used for noncommercial personal transportation in the state. The bill
required that CARB set GHG emission standards for motor vehicles manufactured in 2009 and all
subsequent model years. CARB adopted the standards in September 2004. When fully phased in,
the near-term (2009–2012) standards will result in a reduction of about 22% in GHG emissions
compared to the emissions from the 2002 fleet, while the mid-term (2013–2016) standards will
result in a reduction of about 30%.
Heavy Duty Diesel Truck and Bus Regulation
CARB adopted the final Heavy Duty Truck and Bus Regulation, Title 13, Division 3, Chapter 1,
Section 2025, on December 31, 2014, to reduce DPM and oxides of nitrogen emissions from
heavy-duty diesel vehicles. The rule requires DPM filters be applied to newer heavier trucks and
buses by January 1, 2012, with older vehicles required to comply by January 1, 2015. The rule will
require nearly all diesel trucks and buses to be compliant with the 2010 model year engine
requirement by January 1, 2023. CARB also adopted an Airborne Toxic Control Measure to limit
idling of diesel-fueled commercial vehicles on December 12, 2013. This rule requires diesel-fueled
vehicles with gross vehicle weights greater than 10,000 pounds to idle no more than 5 minutes at
any location (13 CCR 2485).
Executive Order S-1-07
EO S-1-07 (January 2007, implementing regulation adopted in April 2009) sets a declining LCFS
for GHG emissions measured in CO2e grams per unit of fuel energy sold in California. The target
of the LCFS is to reduce the carbon intensity of California passenger vehicle fuels by at least 10%
by 2020 (17 CCR 95480 et seq.). The carbon intensity measures the amount of GHG emissions in
the lifecycle of a fuel, including extraction/feedstock production, processing, transportation, and
final consumption, per unit of energy delivered.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-22
Senate Bill 375
SB 375 (Steinberg) (September 2008) addresses GHG emissions associated with the transportation
sector through regional transportation and sustainability plans. SB 375 requires CARB to adopt
regional GHG reduction targets for the automobile and light-truck sector for 2020 and 2035 and
to update those targets every 8 years. SB 375 requires the state’s 18 regional Metropolitan Planning
Organizations (MPOs) to prepare a Sustainable Communities Strategy as part of their Regional
Transportation Plan that will achieve the GHG reduction targets set by CARB. If an MPO is unable
to devise a Sustainable Communities Strategy to achieve the GHG reduction target, the MPO must
prepare an Alternative Planning Strategy demonstrating how the GHG reduction target would be
achieved through alternative development patterns, infrastructure, or additional transportation
measures or policies.
Pursuant to Government Code, Section 65080(b)(2)(K), a Sustainable Communities Strategy does
not (i) regulate the use of land; (ii) supersede the land use authority of cities and counties; or (iii)
require that a city’s or county’s land use policies and regulations, including those in a general plan,
be consistent with it. Nonetheless, SB 375 makes regional and local planning agencies responsible
for developing those strategies as part of the federally required metropolitan transportation
planning process and the state-mandated housing element process.
In September 2010, CARB adopted the SB 375 targets for the regional MPOs. CARB set a target
of 7% per capita reduction by 2020 and a 15% per capita reduction by 2035 for the Bay Area. The
Association of Bay Area Governments and the Metropolitan Transportation Commission, which
is the MPO for the Bay Area, adopted the Plan Bay Area: Regional Transportation Plan and
Sustainable Communities Strategy for the San Francisco Bay Area 2017– 2040 (Plan Bay Area)
in July 2017 (ABAG and MTC 2017). The Plan Bay Area is a long-range plan for transportation
projects within the planning area and established 13 performance targets covering three broad areas
(the environment, equity, and the economy) to achieve the following goals/outcomes: climate
protection, adequate housing, healthy and safe communities, open space and agricultural
preservation, equitable access, economic vitality, and transportation system effectiveness. Two of
these targets are mandatory to comply with SB 375, and the Plan Bay Area establishes strategies
to achieve 16% reduction per capita in GHG emissions from light-trucks and cars by 2035 (climate
protection goal), and plans to house 100% of the region’s projected growth (from a 2010 baseline
year) by income level without displacing current low-income residents (adequate housing goal).
Advanced Clean Cars Program and Zero-Emissions Vehicle Program
The Advanced Clean Cars Program (January 2012) is a new emissions-control program for model
years 2015 through 2025. The program combines the control of smog- and soot-causing pollutants
and GHG emissions into a single coordinated package. The package includes elements to reduce
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-23
smog-forming pollution, reduce GHG emissions, promote clean cars, and provide the fuels for
clean cars (CARB 2012). To improve air quality, CARB has implemented new emission standards
to reduce smog-forming emissions beginning with 2015 model year vehicles. It is estimated that
in 2025 cars will emit 75% less smog-forming pollution than the average new car sold today. To
reduce GHG emissions, CARB, in conjunction with the EPA and the NHTSA, adopted new GHG
standards for model year 2017 to 2025 vehicles; the new standards are estimated to reduce GHG
emissions by 34% in 2025. The Zero-Emissions Vehicle Program will act as the focused
technology of the Advanced Clean Cars Program by requiring manufacturers to produce increasing
numbers of zero-emissions vehicles and plug-in hybrid EVs in the 2018 to 2025 model years.
Executive Order B-16-12
EO B-16-12 (March 2012) required that state entities under the governor’s direction and control
support and facilitate the rapid commercialization of zero-emissions vehicles. It ordered CARB,
CEC, CPUC, and other relevant agencies to work with the Plug-in Electric Vehicle Collaborative
and the California Fuel Cell Partnership to establish benchmarks to help achieve benchmark goals
by 2015, 2020, and 2025. On a statewide basis, EO B-16-12 established a target reduction of GHG
emissions from the transportation sector equaling 80% less than 1990 levels by 2050. This
directive did not apply to vehicles that have special performance requirements necessary for the
protection of the public safety and welfare.
Assembly Bill 1236
AB 1236 (October 2015) (Chiu) required a city, county, or city and county to approve an
application for the installation of EV charging stations, as defined, through the issuance of
specified permits, unless the city or county makes specified written findings based upon substantial
evidence in the record that the proposed installation would have a specific, adverse impact upon
the public health or safety, and there is no feasible method to satisfactorily mitigate or avoid the
specific, adverse impact. The bill provided for appeal of that decision to the planning commission,
as specified. The bill provided that the implementation of consistent statewide standards to achieve
the timely and cost-effective installation of EV charging stations is a matter of statewide concern.
The bill required EV charging stations to meet specified standards. The bill required a city, county,
or city and county with a population of 200,000 or more residents to adopt an ordinance, by
September 30, 2016, that created an expedited and streamlined permitting process for EV charging
stations, as specified. The bill also required a city, county, or city and county with a population of
less than 200,000 residents to adopt this ordinance by September 30, 2017.

Water
Executive Order B-29-15
In response to the on-going drought in California, EO B-29-15 (April 2015) set a goal of achieving
a statewide reduction in potable urban water usage of 25% relative to water use in 2013. The term
of the EO extended through February 28, 2016, although many of the directives have become
permanent water-efficiency standards and requirements. The EO includes specific directives that
set strict limits on water usage in the state. In response to EO B-29-15, the California Department
of Water Resources has modified and adopted a revised version of the Model Water Efficient
Landscape Ordinance that, among other changes, significantly increases the requirements for
landscape water use efficiency and broadens its applicability to include new development projects
with smaller landscape areas.
Solid Waste
California Integrated Solid Waste Management Act – Assembly Bill 939
Assembly Bill 939, passed in 1989, mandated a focus on the conservation of natural resources.
Cities and counties were required to create comprehensive source reduction, recycling, and
composting programs (Public Resources Code Section 40000 et seq.). The goal of these programs
is to reduce the amount of waste sent to landfills by 50%. The focus of this bill was a major change,
shifting the emphasis from landfill disposal toward waste reduction, recycling, and composting
whenever possible. This approach aims to conserve natural resources, save energy, decrease
pollution, and provide new jobs in the waste industry.
Assembly Bill 939 established the following priorities for waste management:
• Waste reduction
• Recycling and composting
• Controlled combustion of waste to generate electricity
• Landfilling
Mandatory Commercial Recycling— AB 341
AB 341 was adopted as part of the AB 32 Scoping Plan by the Air Resources Board pursuant to
the California Global Warming Solutions Act on January 17, 2012. The legislation declares as a
policy goal of the state that not less than 75% of solid waste generated be source reduced, recycled,
or composted by the year 2020. The regulation requires businesses that generate 4 cubic yards or
more of commercial solid waste per week and multifamily residential dwellings of five units or
more to arrange for recycling services. The measure focuses on increasing commercial waste
diversion to reduce greenhouse gas emissions.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-25
Mandatory Commercial Organics Recycling—AB 1826
AB 1826 was enacted in October 2014 in order to divert commercial organic waste from landfills.
The measure requires businesses and multifamily residential dwellings of five or more units to
recycle organic waste on and after April 1, 2016 depending on how much solid waste they generate
per week. The law includes phasing of requirements over time to ensure that the minimum
threshold of organic waste generation by businesses decreases gradually.
Mandatory Organics Recycling—SB 1383
Senate Bill 1383 was passed in September 2016, which established methane emissions reduction
targets to reduce emissions from short-lived climate pollutants. SB 1383 aims to achieve a 50
percent reduction in the 2014 level of statewide organic waste disposal by 2020 and a 75 percent
reduction by 2025. Cities and Counties are required to implement comprehensive organic waste
diversion programs that focus on recovering edible food for human consumption and diverting
organic material from the landfill. The goal is to reduce greenhouse gas emissions, increase organic
waste diversion from landfills, feed people, and maximize use of existing resources. SB 1383
established the following requirements for Jurisdictions:
• Mandatory organics collection program
• Container contamination minimization
• Container color requirement
• Container labeling requirement
• Edible Food Recovery Program
• Organic waste recycling capacity planning
• Procurement of recovered organic waste products
• Enforcement Program
Other State Actions
Senate Bill 97
SB 97 (Dutton) (August 2007) directed the Governor’s Office of Planning and Research to develop
guidelines under CEQA for the mitigation of GHG emissions. In 2008, the Governor’s Office of
Planning and Research issued a technical advisory as interim guidance regarding the analysis of GHG
emissions in CEQA documents. The advisory indicated that the lead agency should identify and
estimate a project’s GHG emissions, including those associated with vehicular traffic, energy
consumption, water usage, and construction activities (OPR 2008). The advisory further recommended
that the lead agency determine significance of the impacts and impose all mitigation measures
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-26
necessary to reduce GHG emissions to a level that is less than significant. The CNRA adopted the
CEQA Guidelines amendments in December 2009, which became effective in March 2010.
Under the amended Guidelines, a lead agency has the discretion to determine whether to use a
quantitative or qualitative analysis or apply performance standards to determine the significance
of GHG emissions resulting from a particular project (14 CCR 15064.4[a]). The Guidelines require
a lead agency to consider the extent to which the project complies with regulations or requirements
adopted to implement a statewide, regional, or local plan for the reduction or mitigation of GHG
emissions (14 CCR 15064.4[b]). The Guidelines also allow a lead agency to consider feasible
means of mitigating the significant effects of GHG emissions, including reductions in emissions
through the implementation of project features or off-site measures. The adopted amendments do
not establish a GHG emission threshold, instead allowing a lead agency to develop, adopt, and
apply its own thresholds of significance or those developed by other agencies or experts. The
CNRA also acknowledges that a lead agency may consider compliance with regulations or
requirements implementing AB 32 in determining the significance of a project’s GHG emissions
(CNRA 2009).
With respect to GHG emissions, the CEQA Guidelines state in Section 15064.4(a) that lead
agencies “should make a good-faith effort, based to the extent possible on scientific and factual
data, to describe, calculate or estimate” GHG emissions. The CEQA Guidelines note that an
agency may identify emissions by either selecting a “model or methodology” to quantify the
emissions or by relying on “qualitative analysis or performance based standards” (14 CCR
15064.4[a]). Section 15064.4(b) states that the lead agency should consider the following when
assessing the significance of impacts from GHG emissions on the environment: (1) the extent a
project may increase or reduce GHG emissions as compared to the existing environmental setting,
(2) whether the project emissions exceed a threshold of significance that the lead agency
determines applies to the project, and (3) the extent to which the project complies with regulations
or requirements adopted to implement a statewide, regional, or local plan for the reduction or
mitigation of GHG emissions (14 CCR 15064.4[b]).
Executive Order S-13-08
EO S-13-08 (November 2008) is intended to hasten California’s response to the impacts of global
climate change, particularly sea level rise. Therefore, the EO directs state agencies to take specified
actions to assess and plan for such impacts. The final 2009 California Climate Adaptation Strategy
report was issued in December 2009 (CNRA 2009), and an update, Safeguarding California:
Reducing Climate Risk, followed in July 2014 (CNRA 2014). To assess the state’s vulnerability,
the report summarizes key climate change impacts to the state for the following areas: agriculture,
biodiversity and habitat, emergency management, energy, forestry, ocean and coastal ecosystems
and resources, public health, transportation, and water. Issuance of Safeguarding California:
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-27
Implementation Action Plans followed in March 2016 (CNRA 2016). In January 2018, the CNRA
released Safeguarding California Plan: 2018 Update, which communicates current and needed
actions that state government should take to build climate change resiliency (CNRA 2018).
Local
Contra Costa County
Contra Costa County General Plan.
The Conservation Element of the Contra Costa County General Plan (Contra Costa County 2005)
contains the following goals and policies that would apply to the project.
Goal 8-K To encourage the use of renewable resources where they are compatible with the
maintenance of environmental quality.
Goal 8-L To reduce energy use in the County to avoid risks of air pollution and energy
shortages which could prevent orderly development.
Goal 8-AB To continue to support Federal, State and regional efforts to reduce air pollution in
order to protect human and environmental health.
Policy 8-49 Commercial wind farms shall be restricted to the south Byron Hills
portion of the County.
Policy 8-51 All new wind turbine applications shall comply, at a minimum, with
the site-specific criteria included in the wind energy conversion
systems regulations in the County Ordinance Code.
Policy 8-100 Vehicular emissions shall be reduced throughout the County.
Policy 8-101 A safe, convenient and effective bicycle and trail system shall be created
and maintained to encourage increased bicycle use and walking as
alternatives to driving.
Policy 8-102 A safe and convenient pedestrian system shall be created and
maintained in order to encourage walking as an alternative to driving.
Contra Costa County Climate Action Plan.
In 2015, the County adopted the Contra Costa County CAP, which provides a GHG emissions
inventory, GHG forecast, GHG reduction target, and a set of strategies to respond to local
contributions to climate change. Based on both the state CEQA Guidelines and Bay Area Air
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-28
Quality Management District (BAAQMD) criteria, the CAP is considered a qualified GHG
reduction strategy (Contra Costa County 2015). The CAP establishes the County GHG reduction
goal of reducing GHGs by 15% below year 2005 levels by 2020, consistent with AB 32. In
addition, the CAP forecasts the potential GHG emissions and potential GHG reductions from
proposed measures through year 2035. The CAP outlines the reduction efforts in six major GHG
source areas, including energy efficiency and conservation, renewable energy, land use and
transportation, solid waste, water conservation, and government operations. In addition, Appendix
E of the County’s CAP includes a consistency checklist through which projects can demonstrate
consistency and thereby conclude that their impacts related to GHG emissions would be less than
significant under CEQA (Appendix F of this Environmental Impact Report).
3.6.3 Thresholds of Significance and Methodology
The significance criteria used to evaluate the project impacts to GHGs/climate change are based
on Appendix G of the CEQA Guidelines. According to Appendix G of the CEQA Guidelines, a
significant impact related to greenhouse gas emissions would occur if the project would:
1. Generate greenhouse gas emissions, either directly or indirectly, that may have a significant
impact on the environment.
2. Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing
the emissions of greenhouse gases.
Global climate change is a cumulative impact; a project participates in this potential impact
through its incremental contribution combined with the cumulative increase of all other sources of
GHGs. There are currently no established thresholds for assessing whether the GHG emissions of
a project, such as the project, would be considered a cumulatively considerable contribution to
global climate change; however, all reasonable efforts should be made to minimize a project’s
contribution to global climate change. In addition, while GHG impacts are recognized exclusively
as cumulative impacts (CAPCOA 2008), GHG emissions impacts must also be evaluated on a
project level under CEQA.
The CEQA Guidelines do not prescribe specific methodologies for performing an assessment, do
not establish specific thresholds of significance, and do not mandate specific mitigation measures.
Rather, the CEQA Guidelines emphasize the lead agency’s discretion to determine the appropriate
methodologies and thresholds of significance consistent with the manner in which other impact
areas are handled in CEQA (CNRA 2009). The State of California has not adopted emission-based
thresholds for GHG emissions under CEQA. The Governor’s Office of Planning and Research’s
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-29
Technical Advisory titled CEQA and Climate Change: Addressing Climate Change through
California Environmental Quality Act (CEQA) Review (OPR 2008) states the following:
Public agencies are encouraged but not required to adopt thresholds of significance
for environmental impacts. Even in the absence of clearly defined thresholds for
GHG emissions, the law requires that such emissions from CEQA projects must be
disclosed and mitigated to the extent feasible whenever the lead agency determines
that the project contributes to a significant, cumulative climate change impact.
Furthermore, the advisory document indicates that “[i]n the absence of regulatory standards for GHG
emissions or other scientific data to clearly define what constitutes a ‘significant impact’, individual
lead agencies may undertake a project-by-project analysis, consistent with available guidance and
current CEQA practice.” Section 15064.7(c) of the CEQA Guidelines specifies that “[w]hen adopting
thresholds of significance, a lead agency may consider thresholds of significance previously adopted
or recommended by other public agencies or recommended by experts, provided the decision of the
lead agency to adopt such thresholds is supported by substantial evidence.”
Separate thresholds of significance have been established by the BAAQMD for operational
emissions from stationary sources (e.g., generators, furnaces, boilers) and nonstationary sources
(e.g., on-road vehicles) (BAAQMD 2017). The threshold for stationary sources is 10,000 MT
CO2e per year (i.e., emissions above this level may be significant). For nonstationary sources, the
following three separate thresholds have been established:
• Compliance with a Qualified Greenhouse Gas Reduction Strategy (i.e., if a project is
found to be out of compliance with a Qualified Greenhouse Gas Reduction Strategy, its
GHG emissions may be significant).
• 1,100 MT CO2e per year (i.e., emissions above this level may be significant).
• 4.6 MT CO2e per service population per year (i.e., emissions above this level may be
significant). (Service population is the sum of residents plus employees expected for a
development project.)
As discussed previously, the County CAP is considered a qualified GHG reduction strategy based
on both the state CEQA Guidelines and BAAQMD criteria (Contra Costa County 2015). Using
the County’s current CAP consistency review checklist (Appendix E of the CAP, Appendix F of
this document) as a guide, this analysis evaluates whether the proposed project would comply with
the County’s CAP. A “yes” or “not applicable” response to each of the CAP Consistency Review
Checklist questions would result in a determination that the proposed project complies with the
County’s CAP. A “no” response demonstrates the project is not fully compliant with the County’s
CAP and additional analysis would be required.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-30
3.6.3.1 Methodology
Construction
Emissions from project construction activities were estimated using the CalEEMod Version
2016.3.2. Construction of the project would result in GHG emissions primarily associated with use
of off-road construction equipment, on-road vendor (material delivery) trucks, and worker
vehicles. All details for construction criteria air pollutants discussed in Section 3.2, Air Quality,
are also applicable for the estimation of construction-related GHG emissions. As such, see Section
3.2 for a discussion of construction emissions calculation methodology and assumptions.
Operations
Emissions from the operational phase of the project were estimated using CalEEMod Version
2016.3.2. Operational year 2029 was assumed based on the first full year of operations. During
long-term operations, the project would generate air pollutants from mobile, energy, and area
sources. Traffic trips were estimated based on the land uses specified in Chapter 2, Project
Description, of this Environmental Impact Report (EIR), and by adjusting default weekday trip
rates in CalEEMod to match those included in the Transportation Impact Analysis Report
(Appendix H) for the land use types.3 The same adjustment factors used for the weekday trip
generation were applied to the default Saturday and Sunday trip rates in CalEEMod. Increased trip
lengths for potential customers based on the rural location of the project, as well as the project
specific vehicle-miles-traveled (VMT) for employees, as described in Chapter 3.13,
Transportation, of this EIR. Non-work trip lengths were increased to account for potentially greater
travel distance for deliveries. Project-related traffic was assumed to include a mixture of vehicles
in accordance with the model outputs for traffic. Default CalEEMod assumptions were used for
building and lighting electricity use, generation of electricity associated with water supply,
treatment, distribution and wastewater treatment, natural gas combustion, and area sources (i.e.,
landscaping, consumer products, and architectural coatings for building maintenance). Solid waste
disposal was adjusted to account for a 50% solid waste diversion rate consistent with AB 939
compliance. Energy use associated with the airport storage facilities was assumed to be equivalent
to a warehouse.
In addition, per the CEC Impact Analysis for the 2019 Update to the California Energy Efficiency
Standards for Residential and Non-Residential Buildings, the first-year savings for newly
constructed nonresidential buildings are 197 gigawatt hours of electricity, 76.6 megawatt of
demand, and 0.27 million therms of gas, representing reductions from the 2016 Title 24 standard
3 The Logistics/ Warehouse/ Distribution land use was modeled in CalEEMod with “Unrefrigerated Warehouse – No
Rail” and “Unrefrigerated Warehouse – With Rail” in order to delineate fleet mix and trip lengths for employees versus
haul trucks, with 69% of trips assumed to be employees and 31% assumed to be trucks, based on the “Warehouse Truck
Trip Study Data Results and Usage” (South Coast Air Quality Management District 2014).
3.6 – GREENHOUSE GAS EMISSIONS

of 10.7%, 9%, and 1%, respectively (CEC 2018a). To take into account energy reductions
associated with compliance with 2019 Title 24, the CalEEMod Title 24 electricity and natural gas
values were reduced by 10.7% and 1%, respectively, for all project buildings. The applied
reductions are anticipated to be conservative as in general, nonresidential buildings built to the
2019 standards are anticipated to use an estimated 30% less energy than those built to the 2016
standards (CEC 2018b).
3.6.4 Impacts Analysis
Impact 3.6-1. The project would generate greenhouse gas emissions, either directly or indirectly,
that may have a significant impact on the environment. (Potentially Significant)
The project would involve the construction and operation of approximately 274,000 square feet of
logistics/warehouse/distribution buildings, 213,000 square feet of light industry/business park,
81,000 square feet of office uses, 91,000 square feet of commercial uses, 128,000 square feet of
airport storage, 154,000 square feet of aviation-related buildings, and associated parking. In
addition, the project would require 0.89 miles of roadway expansion and 2.6 miles of water
infrastructure installation. Construction is anticipated to take approximately 10 years to complete.
Total construction GHG emissions were estimated for all project components, including roadway
improvements and water infrastructure, and amortized assuming a 30-year project lifetime. Long-
term operational emissions would occur over the life of the project, with complete project build-
out operations beginning in year 2029. CalEEMod was used to estimate GHG emissions from
motor vehicle trips, grid electricity usage, solid waste, and other sources (including area sources
and water/wastewater conveyance). These emissions are depicted in Table 3.6-3 for disclosure,
with detailed model outputs and assumptions included in Appendix C.

incorporate the 50% solid waste diversion rate consistent with AB 939 compliance, even though this measure is not considered a separate
mitigation measure.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-32
As depicted in Table 3.6-3 above, the project would result in an increase of GHG emissions,
primarily associated with vehicular traffic (mobile sources) and energy use. However, in order to
determine significance, the project was compared to the County’s CAP consistency checklist. The
County’s CAP consistency checklist includes criteria against which a project must be evaluated.
Projects that are consistent with the applicable criteria are considered consistent with the County’s
CAP and would not have a significant GHG impact. As shown in the completed CAP Checklist in
Appendix F, the project would not meet the following County CAP requirements:
• EE 1: New nonresidential development will install high efficiency appliances and insulation.
• RE 1: New residential and nonresidential development will meet the standards to be solar
ready as defined by the California Building Standards Code.
• LUT 2: New multifamily (greater than five units) and nonresidential (greater than 10,000
square feet) developments will provide EV charging stations in designated parking spots.
• LUT 4: New residential and nonresidential development will be located within one half-mile
of a Bay Area Rapid Transit or Amtrak station, or within one quarter-mile of a bus station.
Since the project would not meet the applicable CAP consistency checklist criteria, it would be
considered inconsistent with the County’s CAP without mitigation. As such, the project would
have a potentially significant impact on climate change.
Impact 3.6-2. The project would conflict with an applicable plan, policy, or regulation
adopted for the purpose of reducing the emissions of greenhouse gases .
(Potentially Significant)
The Scoping Plan, approved by CARB on December 12, 2008, provides a framework for actions
to reduce California’s GHG emissions and requires CARB and other state agencies to adopt
regulations and other initiatives to reduce GHGs. As such, the Scoping Plan is not directly
applicable to specific projects. Relatedly, in the Final Statement of Reasons for the Amendments
to the CEQA Guidelines, the CNRA observed that “the [Scoping Plan] may not be appropriate for
use in determining the significance of individual projects because it is conceptual at this stage and
relies on the future development of regulations to implement the strategies identified in the
Scoping Plan” (CNRA 2009). Under the Scoping Plan, however, there are several state regulatory
measures aimed at the identification and reduction of GHG emissions. CARB and other state
agencies have adopted many of the measures identified in the Scoping Plan. Most of these
measures focus on area source emissions (e.g., energy usage, high -GWP GHGs in consumer
products) and changes to the vehicle fleet (i.e., hybrid, electric, and more fuel-efficient vehicles)
and associated fuels (e.g., LCFS), among others. To the extent that these regulations are applicable
to the project, the project would comply with all regulations adopted in furtherance of the Scoping
Plan to the extent required by law.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-33
Regarding consistency with SB 32 (goal of reducing GHG emissions to 40% below 1990 levels
by 2030) and EO S-3-05 (goal of reducing GHG emissions to 80% below 1990 levels by 2050),
there are no established protocols or thresholds of significance for that future-year analysis.
However, CARB has expressed optimism with regard to both the 2030 and 2050 goals. It states in
the First Update that “California is on track to meet the near-term 2020 GHG emissions limit and
is well positioned to maintain and continue reductions beyond 2020 as required by AB 32” (CARB
2014). With regard to the 2050 target for reducing GHG emissions to 80% below 1990 levels, the
First Update states the following (CARB 2014):
This level of reduction is achievable in California. In fact, if California realizes the
expected benefits of existing policy goals (such as 12,000 megawatts of renewable
distributed generation by 2020, net zero energy homes after 2020, existing building
retrofits under Assembly Bill 758, and others) it could reduce emissions by 2030 to
levels squarely in line with those needed in the developed world and to stay on track
to reduce emissions to 80% below 1990 levels by 2050. Additional measures,
including locally driven measures and those necessary to meet federal air quality
standards in 2032, could lead to even greater emission reductions.
In other words, CARB believes that the state is on a trajectory to meet the 2030 and 2050 GHG
reduction targets set forth in AB 32, SB 32, and EO S-3-05. This is confirmed in the Second
Update, which states (CARB 2017a),
This Plan draws from the experiences in developing and implementing previous
plans to present a path to reaching California’s 2030 GHG reduction target. The
Plan is a package of economically viable and technologically feasible actions to not
just keep California on track to achieve its 2030 target, but stay on track for a low-
to zero-carbon economy by involving every part of the state.
The 2017 Scoping Plan also states that although “the Scoping Plan charts the path to achieving the
2030 GHG emissions reduction target, we also need momentum to propel us to the 2050 statewide
GHG target (80% below 1990 levels). In developing this Scoping Plan, we considered what
policies are needed to meet our mid-term and long-term goals” (CARB 2017a).
With respect to future GHG targets under SB 32 and EO S-3-05, CARB has made clear its legal
interpretation that it has the requisite authority to adopt whatever regulations are necessary, beyond
the AB 32 horizon year of 2020, to meet SB 32’s 40% reduction target by 2030 and EO S-3-05’s
80% reduction target by 2050; this legal interpretation by an expert agency provides evidence that
future regulations will be adopted to continue the state on its trajectory toward meeting these future
GHG targets. However, as described in Impact 3.6-1, the project would not be consistent with the
County’s CAP, which is considered a qualified GHG reduction plan pursuant to CEQA, and
established based on the goal of AB 32 to reduce statewide emissions to 1990 levels by 2020.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-34
Therefore, the project would also be considered inconsistent with implementation of any of the
above-described GHG reduction goals for 2030 or 2050.
Based on the above considerations, the project would conflict with an applicable plan, policy, or
regulation adopted for the purpose of reducing the emissions of GHGs. This impact would be
potentially significant.
3.6.5 Mitigation Measures
The following mitigation measures would reduce potentially significant impacts during operation.
These measures would be applied to individual development projects implemented under the
Byron Airport Development Program. As a conservative approach, the reductions from Mitigation
Measure (MM) GHG-1, MM-GHG-2, and MM-GHG-3 were not quantified due to the lack of
clarity on the quantity of reductions associated with these mitigation measures.
MM-GHG-1 The individual development projects shall include the following transit-oriented
and alternative transportation development design features to reduce the use of
single-occupancy fossil fueled vehicles and vehicle miles traveled:
• Provide preferred parking for zero/low emission vehicles. Bicycle parking
and only the minimum amount of auto parking shall be provided to
encourage alternative forms of travel.
• Install conduits from the building(s) to the parking lot(s), to allow for
installation of electric vehicle charging stations for vehicles. The proportion
of electric vehicle parking spaces shall comply with the applicable
California Green Building Standards Code.
• The proposed project shall promote ridesharing programs through a
multifaceted approach, such as designating a certain percentage of parking
spaces for ridesharing vehicles; designating adequate passenger loading and
unloading and waiting areas for ridesharing vehicles; or providing a website
or message board for coordinating rides.
• The proposed project shall implement marketing strategies to reduce
commute trips. Information sharing and marketing are important
components to successful commute trip-reduction strategies. Implementing
commute trip-reduction strategies without a complementary marketing
strategy would result in lower vehicle miles traveled reductions. Marketing
strategies may include: new employee orientation of trip reduction and
alternative mode options; event promotions; or publications.
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-35
MM-GHG-2 The individual development projects shall include the following design features to
reduce the demand for energy use and greenhouse gas emissions:
• Obtain Leadership in Energy and Environmental Design (LEED)
Certification for building construction, where feasible.
• Provide the maximum amount of skylights to reduce electricity use
associated with interior lighting.
• All facility lighting shall meet or exceed the applicable Title 24 requirements.
• All installed appliances (e.g., washer/dryers, refrigerators, dishwashers)
shall be Energy Star rated or equivalent.
• Design proposed buildings with:
o Roof structure with additional load (defined as 1 to 2 pounds per square
foot) capacity to allow the future installation of solar panels without
retrofitting. The installation of solar panels would comply with the policy
and procedures set forth in the Interim Policy for FAA Review of Solar
Energy System Projects on Federally Obligated Airports (78 FR 63276).
o Installation of an above market sized electrical infrastructure system
(larger electrical room for future expansion, underground conduits (car,
truck and loading dock) for future electrical charging systems, as well
as additional conduits into the grid system for future expand-ability.
MM-GHG-3 The individual development projects shall incorporate the following design features
to conserve water:
• Install low flow plumbing fixtures, such as faucets, toilets, and showers.
• Utilize water efficient landscaping to reduce the usage of outdoor water on
the premises.
• Construct dual plumbing for both potable and recycled water for exterior
landscape irrigation, unless determined infeasible by Department of
Conservation and Development, Current Planning Division.
3.6.6 Level of Significance After Mitigation
With implementation of MM-GHG-1, MM-GHG-2, and MM-GHG-3 the project would be
consistent with the CAP checklist items EE 1 (high efficiency appliances and insulation), RE 1
(solar ready), and LUT 2 (EV charging stations). However, based on the rural location of Byron
Airport, the project would not comply with LUT 4 (located within one half-mile of a Bay Area
Rapid Transit or Amtrak station or within one quarter-mile of a bus station). Therefore, the project
3.6 – GREENHOUSE GAS EMISSIONS
Byron Airport Development Program EIR 9269
February 2022 3.6-36
would not comply with the County CAP and the cumulative GHG impact would remain
significant and unavoidable.
3.6.7 Cumulative Impacts
As discussed in Section 3.6.3, GHG emissions and climate change are by their very nature
considered to be cumulative impacts. Therefore, cumulative impacts are taken into account in the
impact analysis in Section 3.6.4.

Byron Airport Development Program EIR 9269
February 2022 3.7-1
3.7 HAZARDS AND HAZARDOUS MATERIALS
This section describes the existing hazardous materials within the vicinity of the Byron Airport
Development Program (project) site, identifies associated regulatory requirements, evaluates
potential impacts, and identifies mitigation measures related to implementation of the proposed
project. This impact analysis in this section is based on the Hazards Assessment prepared by Dudek
(2018), attached as Appendix G to this Environmental Impact Report (EIR).
3.7.1 Existing Conditions
The project site is located south of Armstrong Road at Byron Hot Springs Road near Byron,
California (Figure 2-1, Project Location, of Chapter 2, Project Description). The project site
consists of 1,319 acres, which includes airport property south of Armstrong Road and an adjacent
11.7-acre parcel with an existing single-family residence located between the airport property and
the Bethany Irrigation District Canal (Figure 2-2, Project Site, of Chapter 2). The study area for
hazardous conditions/materials includes all areas identified for development in the Byron Airport
Master Plan and the 11.7-acre potential acquisition parcel (Figure 3.7-1, Hazards Site Map). It
should be noted that the proposed project includes development on only 70 acres (Figure 2-3,
Development Area and Safety Zones, of Chapter 2).
The Byron Airport was opened to the public in 1994. Prior to the development of the airport, the
project site appeared to include the smaller Byron Airpark in the northwestern portion of the
project site, an agricultural area in the eastern portion of the project site, and two residences in the
central portion of the project site. Some of the surrounding land was developed for agriculture and
residences as early as 1949. The project site currently contains structures associated with the
function of the airport such as a terminal, hangars, aircraft maintenance, fueling facilities, and
airport administrative offices. The majority of the project site is vacant land, including land
managed for habitat. A single-family house is located on the 11.7-acre parcel in the northeast
corner of the project site. The surrounding area consists of agricultural land, vacant land, and some
residential development.
The existing conditions were assessed using the following sources: (1) regulatory files searched
by Environmental Data Resources (EDR), (2) regulatory files available from Contra Costa Health
Services Hazardous Materials Programs, (3) historical aerial photographs and topographic maps,
(4) mapped pipeline information, and (5) additional site documents (see Appendix G of this EIR).
The project site was identified in the EDR report as being listed in databases associated with
aboveground petroleum storage tanks and generation and off-site disposal of hazardous materials.
The site was also listed in the Statewide Environmental Evaluation and Planning System
underground storage tank (UST) database, which may be associated with a possible UST on the
former Byron Airpark site. It is not known if the potential UST was removed or where it was
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-2
located. No information about a UST was included in the Contra Costa County (County) files
reviewed. However, an additional site document reviewed indicated the former presence of two
fuel islands, one of which appears to have been located in the northern portion of the project site.
Information regarding the use of hazardous materials at the project site was obtained from the
Contra Costa Health Services Department and other records reviewed. The files indicate the
following fuel and oil storage, use, and releases at the project site:
• 10,000-gallon aviation fuel aboveground storage tank (AST)
• 1,000-gallon gasoline AST
• 200-gallon diesel AST (adjacent)
• 250-gallon waste oil AST
• 100-gallon aviation fuel release (remediated)
• Potential presence of USTs or an additional fuel AST (indicated by former fuel islands);
UST present on or near the project site in 1991 (per EDR report)
• Minor releases from waste oil drums
• At least one oil/water separator near the 250-gallon waste oil AST (Figure 3.7-1);
additional oil/water separator potentially located near the aviation fuel AST
• Water from the oil/water separator(s) running to the leach field
• A hazardous liquid (crude oil) pipeline located in the western portion of the project site
(Figure 3.7-1)
Based on a review of the EDR report, it is not likely that operations or releases at surrounding sites
have impacted environmental conditions at the project site. Additionally, based on review of
historical aerial photographs, it appears that an area in the eastern portion of the project site was
used for agriculture from the 1960s until the 1980s. Pesticides may have been used at the project
site during this time.
Three abandoned oil and gas wells are located within the Airport Boundary, south-southeast of the
airport near Byron Hot Springs Road. Based on information provided by CalGEM, these wells
have been abandoned, but not to current requirements prescribed by law (CalGEM 2021). These
wells are identified by CalGEM as ‘Hannum Trust #1’, ‘Hannum Trust #2’, and ‘ROCO-Hannum
Trust #2’. These wells are located within the area proposed for Habitat Management (see Figure
2-3).
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-3
3.7.1.1 Wildland Fire Severity Zone
The project site is located in a Moderate Fire Hazard Severity Zone within the Local Responsibility
Area based on the California Department of Forestry and Fire Protection (CAL FIRE) Fire Hazard
Severity Zoning map (CAL FIRE 2007). The project site is not within a High or Very High Fire
Hazard Severity Zone (Figure 3.7-2, Wildfire Hazards).
3.7.2 Relevant Plans, Policies, and Ordinances
This section includes applicable federal, state, and local laws; regulatory guidance; and General
Plan goals and policies that govern environmental hazards and hazardous materials in the County.
Federal
Federal Fire Prevention and Control Act of 1974/Federal Fire Safety Act of 1992
The Federal Fire Prevention and Control Act of 1974 was created to provide federal assistance to
states and communities for research and development, education, and training on fire problems,
setting priorities, and identifying possible solutions to problems. The 1974 act was amended in the
Federal Fire Safety Act of 1992 to require, among other things, automatic sprinkler systems or an
equivalent level of safety on buildings having more than 25 employees that have been purchased,
constructed, or renovated with federal funds.
Aviation and Transportation Security Act
On November 19, 2001, the Aviation and Transportation Security Act was enacted, which created the
Transportation Security Administration (TSA) and transferred authority for enforcement of civil aviation
security requirements (Title 49 Code of Federal Regulations [CFR] Part 1542) from the Federal Aviation
Administration (FAA) to TSA. TSA has operated its civil enforcement program utilizing many of the
FAA procedures and policies already in place. TSA’s stated mission is to “protect the nation’s
transportation systems to ensure freedom of movement for people and commerce”. The TSA’s Office of
Security Operations provides “risk‐based, adaptive security” that includes airport checkpoint and
baggage screening operations, regulatory compliance, cargo inspections, and other specialized programs
designed to secure transportation (14 CFR 139). The airport is a federally regulated facility under 14 CFR
139. The airport is required to have an Airport Operating Certificate per 14 CFR 139, in addition to
meeting numerous federal regulations. These regulations include standards for aircraft rescue and
firefighting equipment and services, including response times and personnel training, the handling and
storing of hazardous materials, and safety inspection and reporting procedures.
Federal Aviation Administration Advisory Circulars
FAA advisory circulars (ACs) include specific guidance on a number of topics related to airport design,
operation, and maintenance. The use of FAA ACs is mandatory for those airport construction projects
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-4
receiving funds under the Airport Improvements Program (see FAA Grant Assurance No. 34, Policies,
Standards, and Specifications). The following ACs are pertinent to fire/emergency services:
• FAA AC 150/5210‐15A, Aircraft Rescue and Firefighting Station Building Design.
Provides additional guidance on the design of the aircraft rescue and firefighting building.
• FAA AC 150/5370‐2G, Operational Safety on Airports During Construction. Sets forth
guidelines for operational safety on airports during construction.
National Fire Protection Association Codes and Standards
The National Fire Protection Association (NFPA) is a membership organization that develops and
monitors the use of over 300 fire codes and standards that have been widely incorporated into state
and local fire codes. There are no legislative enforcement mechanisms in place.
By working through numerous technical committees, the NFPA uses a consensus approach to
solve many safety‐related issues. According to the NFPA website, the standards are updated every
3–5 years (NFPA 2018).
Comprehensive Environmental Response, Compensation, and Liability Act
The Comprehensive Environmental Response, Compensation, and Liability Act, commonly
known as Superfund, was enacted by congress on December 11, 1980. It established prohibitions
and requirements concerning closed and abandoned hazardous waste sites, provided for liability
of persons responsible for releases of hazardous waste at these sites, and established a trust fund
to provide for cleanup when no responsible party could be identified. Amended in 1986, the act
establishes two primary actions: (1) to coordinate short-term removal of hazardous materials and
(2) to coordinate and manage the long-term remedial response actions associated with sites
identified on the U.S. Environmental Protection Agency (EPA) National Priorities List. The
National Priorities List lists known or threatened releases of hazardous substances, pollutants, or
contaminants. The Comprehensive Environmental Response, Compensation, and Liability
Information System is a national database and management system used by the EPA to track
cleanup activities at Comprehensive Environmental Response, Compensation, and Liability Act
hazardous waste sites.
Resource Conservation and Recovery Act
The Resource Conservation and Recovery Act (RCRA) of 1976 (42 USC 6901–6992) established
a program administered by the EPA for regulation of the generation, transportation, treatment,
storage, and disposal of hazardous waste. RCRA was amended in 1984 by the Hazardous and Solid
Waste Act (PL 98-616), which affirmed and extended the “cradle-to-grave” system of regulating
hazardous wastes. The use of certain techniques for the disposal of some hazardous wastes was
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-5
specifically prohibited by the Hazardous and Solid Waste Act. Under the authority of RCRA, the
regulatory framework for managing hazardous waste, including requirements for entities that
generate, store, transport, treat, and dispose of hazardous waste is found in 40 CFR, Parts 260 –
299. California is delegated authority from the EPA to enforce RCRA and its own Hazardous
Waste Control Act (see following sections) in California. The EPA retains enforcement authority.
RCRA also set forth a framework for the management of non-hazardous solid wastes. The 1986
amendments to RCRA enabled the EPA to address environmental problems that could result from
underground tanks storing petroleum and other hazardous substances. The 1984 federal Hazardous
and Solid Waste Amendments to RCRA are focused on waste minimization and phasing out land
disposal of hazardous waste, as well as corrective action for releases. Some of the other mandates
of this law include increased enforcement authority for EPA, more stringent hazardous waste
management standards, and a comprehensive UST program.
Hazardous Materials Transportation Act
The U.S. Department of Transportation regulates hazardous materials transportation under Title
49 of the United States Code. State agencies with primary responsibility for enforcing federal and
state regulations and responding to hazardous materials transportation emergencies are the
California Highway Patrol and the California Department of Transportation. These agencies also
govern permitting for hazardous materials transportation.
State
California Accidental Release Prevention Program
The California Accidental Release Prevention (CalARP) Program (19 CCR 2735.1 et seq.)
regulates facilities that use or store regulated substances, such as toxic or flammable chemicals, in
quantities that exceed established thresholds. The overall purpose of CalARP is to prevent
accidental releases of regulated substances and reduce the severity of releases that may occur. The
CalARP Program meets the requirements of the EPA Risk Management Program, which was
established pursuant to the Clean Air Act Amendments.
California Hazardous Materials Release Response Plans and Inventory
In California, the handling and storage of hazardous materials is regulated by Division 20, Chapter
6.95, of the California Health and Safety Code (Section 25500 et seq.). Under Sections 25500–
25543.3, facilities handling hazardous materials are required to prepare a Hazardous Materials
Business Plan (HMBP). HMBPs contain basic information about the location, type, quantity, and
health risks of hazardous materials stored, used, or disposed of in the state.
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-6
Chapter 6.95 of the California Health and Safety Code establishes minimum statewide standards for
HMBPs. Each business shall prepare an HMBP if that business uses, handles, or stores a hazardous
material (including hazardous waste) or an extremely hazardous material in disclosable quantities
greater than or equal to the following (California Health and Safety Code, Section 25503.5):
• 500 pounds of a solid substance
• 55 gallons of a liquid
• 200 cubic feet of compressed gas
• A hazardous compressed gas in any amount (highly toxic with a Threshold Limit Value of
10 parts per million or less)
• Extremely hazardous substances in threshold planning quantities
In addition, in the event that a facility stores quantities of specific acutely hazardous materials
above the thresholds set forth by California code, facilities are also required to prepare a risk
management plan and CalARP plan. The risk management plan and accidental release prevention
plan provide information about the potential impact zone of a worst-case release and require plans
and programs designed to minimize the probability of a release and mitigate potential impacts.
California Hazardous Waste Control Act
The Department of Toxic Substances Control is responsible for the enforcement of the Hazardous
Waste Control Act (California Health and Safety Code, Section 25100 et seq.), which creates the
framework under which hazardous wastes are managed in California. The law provides for the
development of a state hazardous waste program that administers and implements the provisions
of the federal RCRA cradle-to-grave waste management system in California. It also provides for
the designation of California-only hazardous waste and development of standards that are equal to
or, in some cases, more stringent than federal requirements. The Hazardous Waste Control Act
lists 791 chemicals and approximately 300 common materials that may be hazardous; establishes
criteria for identifying, packaging, and labeling hazardous wastes; prescribes management
controls; establishes permit requirements for treatment, storage, disposal, and transportation; and
identifies some wastes that cannot be disposed of in landfills.
According to Title 22 of the California Code of Regulations, Sections 66001 et seq., substances having
a characteristic of toxicity, ignitability, corrosivity, or reactivity are considered hazardous. Hazardous
wastes are hazardous substances that no longer have a practical use, such as material that has been
abandoned, discarded, spilled, contaminated, or are being stored prior to proper disposal.
Toxic substances may cause short-term or long-lasting health effects ranging from temporary effects
to permanent disability or death. For example, toxic substances can cause eye or skin irritation,
disorientation, headache, nausea, allergic reactions, acute poisoning, chronic illness, or other adverse
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-7
health effects if human exposure exceeds certain levels (the level depends on the substance
involved). Carcinogens (substances known to cause cancer) are a special class of toxic substances.
Examples of toxic substances include most heavy metals, pesticides, and benzene (a carcinogenic
component of gasoline). Ignitable substances (e.g., gasoline, hexane, and natural gas) are hazardous
because of their flammable properties. Corrosive substances (e.g., strong acids and bases such as
sulfuric [battery] acid or lye) are chemically active and can damage other materials or cause severe
burns upon contact. Reactive substances (e.g., explosives, pressurized canisters, and pure sodium
metal, which react violently with water) may cause explosions or generate gases or fumes.
Other types of hazardous materials include radioactive and biohazardous materials. Radioactive
materials and wastes contain radioisotopes, which are atoms with unstable nuclei that emit ionizing
radiation to increase their stability. Radioactive waste mixed with chemical hazardous waste is
referred to as “mixed wastes.” Biohazardous materials and wastes include anything derived from
living organisms. They may be contaminated with disease-causing agents, such as bacteria or
viruses (22 CCR 66261.1 et seq.).
California Occupational Safety and Health Administration
The California Occupational Safety and Health Administration is the primary agency responsible
for worker safety in the handling and use of chemicals in the workplace. California Occupational
Safety and Health Administration standards are generally more stringent than federal regulations.
The employer is required to monitor worker exposure to listed hazardous substances and notify
workers of exposure (8 CCR 330 et seq.). The regulations specify requirements for employee
training, availability of safety equipment, accident prevention programs, and hazardous substance
exposure warnings. The employer is also required, among other things, to have an Illness and
Injury Prevention Program.
Certified Unified Program
The California EPA implements and enforces a statewide hazardous materials program known as
the Certified Unified Program, established by Senate Bill 1802 to consolidate, co ordinate, and
make consistent the administrative requirements, permits, inspections, and enforcement activities
for the following environmental and emergency management programs for hazardous materials:
• Hazardous Materials Release Response Plans and Inventories (Business Plans)
• CalARP Program
• UST Program
• Aboveground Petroleum Storage Act Requirements for Spill Prevention, Control, and
Countermeasure Plans
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-8
• Hazardous Waste Generator and On-Site Hazardous Waste Treatment Programs
• California Uniform Fire Code, Hazardous Materials Management Plans, and Hazardous
Material Inventory Statements
To ensure consistency in the administrative requirements, permits, inspections, and enforcement
related to the handling and storage of hazardous wastes and materials, California EPA oversees
the Certified Unified Program and certifies local government agencies as Certified Unified
Program Agencies to implement hazardous waste and materials standards. In the County, the
Contra Costa County Health Services Department is the Certified Unified Program Agency.
Cortese List
The Hazardous Wastes and Substances Site (Cortese) List, maintained by California EPA, is a list
of data resources used by state and local agencies and developers to provide information about the
location of hazardous materials release sites, per Government Code Section 65962.5. The
Department of Toxic Substances Control, State Water Board, and California Department of
Resources Recycling and Recovery all contribute data related to hazardous waste and substances
sites, leaking USTs, solid waste disposal sites with waste constituents above hazardous waste
levels, active Cease and Desist Orders and Cleanup and Abatement Orders, and hazardous waste
facilities subject to corrective action.
General National Pollutant Discharge Elimination System Permits and Waste
Discharge Requirements
To enable efficient permitting under both the Clean Water Act and the Porter-Cologne Act, the
State Water Resources Control Board and the Regional Water Quality Control Board run permit
programs that group similar types of activities that have similar threats to water quality. These
general permit programs include the Phase I Municipal Separate Storm Sewer System1 Permit, the
construction general permit, the industrial general permit, and other general permits for low-threat
discharges. The construction and industrial stormwater programs are administered by the State
Water Resources Control Board, while the Phase I Municipal Separate Storm Sewer System Permit
and other general Waste Discharge Requirements are administered by the Central Valley Regional
Water Quality Control Board. Point source discharges or other activities that threaten water quality
that are not covered under a general permit must seek individual National Pollutant Discharge
Elimination System permits and/or Waste Discharge Requirements, depending on the type,
location, and destination of the discharge. For these types of discharges, the initial step in the
1 A Municipal Separate Storm Sewer System is defined in as a conveyance or system of conveyances (including
roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, human -made channels, or
storm drains) that serve medium and large cities or certain counties with populations of 100,000 or more.
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-9
process is to submit a Report of Waste Discharge to the Central Valley Regional Water Quality
Control Board, who then determines the appropriate permitting pathway.
Applicable National Pollutant Discharge Elimination System requirements for the proposed
project are discussed in Section 3.8, Hydrology and Water Quality, of this EIR.
California Building Standards Code
The 2016 California Building Standards Code (24 CCR) was published July 1, 2016, with an
effective date of January 1, 2017. A supplement was published January 1, 2017, with an effective
date of July 1, 2018. The California Building Standards Code is a compilation of three types of
building criteria from three different origins: (1) building standards that have been adopted by state
agencies without change from building standards contained in national model codes; (2) building
standards that have been adopted and adapted from the national model code standards to meet
California conditions; and (3) building standards, authorized by the California legislature, that
constitute extensive additions not covered by the model codes that have been adopted to address
particular California concerns.
State Fire Regulations
The California Fire Code (CFC) is Part 9 of Title 24 of the California Code of Regulations, which
includes regulations concerning building standards (as also set forth in the California Building
Code), fire protection and notification systems, fire protection devices such as extinguishers and
smoke alarms, high-rise building and childcare facility standards, and fire suppression training. It
was created by the California Building Standards Commission and is based on the International
Fire Code created by the International Code Council. It is the primary means for authorizing and
enforcing procedures and mechanisms to ensure the safe handling and storage of any substance
that may pose a threat to public health and safety. The CFC regulates the use, handling, and storage
requirements for hazardous materials at fixed facilities. The CFC and the California Building Code
use a hazard classification system to determine what protective measures are required to protect
fire and life safety (24 CCR Part 9). These measures may include construction standards,
separations from property lines, and specialized equipment. To ensure that these safety measures
are met, the CFC employs a permit system based on hazard classification. The CFC is updated
every 3 years and was most recently updated in 2016, with an effective date of January 1, 2017.
Wildfire Protection
Fire safety is regulated throughout the state through a variety of fire protection laws, including the
designation of fire hazard areas. California Public Resources Code, Sections 4251–4299, provide for
permitted activities and procedures for development within fire hazard areas, including the
establishment and management of defensible space (buffers managed to ensure fuel reduction around
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-10
structures). CAL FIRE regulates State Responsibility Areas (SRAs), which are areas where the state
has primary responsibility for fire prevention and protection services (as opposed to local and/or federal
agencies). Within SRAs, developers must provide for emergency access, signs and building
numbering, private water supply reserves for emergency fire use, and vegetation modifications.
The majority of the project site (excluding a portion south of Holey Road) is located within an
SRA and is identified as a Moderate Fire Hazard Severity Zone (CAL FIRE 2007). The project
site is within CAL FIRE’s Santa Clara Unit.
California Public Resources Code, Section 4290, required CAL FIRE to adopt regulations
regarding minimum requirements for road access to land uses within SRAs and high fire hazard
areas. These regulations are now contained within the SRA Fire Safe Regulations, California Code
of Regulations, Title 14, Section 1270 et seq. To provide for two-way traffic flow to support
emergency vehicle and civilian egress, all roads within an SRA shall be constructed to provide a
minimum of two 10-foot traffic lanes, not including shoulder and striping.
California Government Code Section 51182 and Public Resources Code, Section 4291, require
fire risk reduction measures to be enforced by local agencies and CAL FIRE for occupied
dwellings or structures. These measures require the following:
• Maintaining a fire break made by removing and clearing away, for a distance of not less
than 100 feet on each side of a dwelling or structure, or to the property line whichever is
nearer, all flammable vegetation or other combustible growth. This does not apply to single
specimen trees, ornamental shrubbery, or similar plants that are used as ground cover, if
they do not form a means of rapidly transmitting fire from the native growth to any dwelling
or structure.
• Maintaining additional fire protection or firebreaks made by removing all brush, flammable
vegetation, or combustible growth that is located within 100 feet from an occupied
dwelling or occupied structure or to the property line, or at a greater distance if required by
state law, or local ordinance, rule, or regulation.
• Removal of that portion of any tree that extends within 10 feet of the outlet of any chimney
or stovepipe.
• Maintaining any tree adjacent to or overhanging any building free of dead or dying wood.
• Maintaining the roof of any structure free of leaves, needles, or other dead vegetative material.

transportation of hazardous materials review regulations and procedures, in
cooperation with the County, to determine means of mitigating the public safety
hazard in urbanized areas.
Contra Costa County Health Services Department
The implementation of the Unified Hazardous Waste and Hazardous Materials Management
Regulatory Program (California Health and Safety Code Chapter 6.11) is managed by the County
Health Services Department, which is certified by the California Secretary of Environmental
Protection. The County Health Services Department manages the regulatory programs for HMBPs,
USTs, hazardous waste generators, and CalARP. The Contra Costa County Hazardous Materials
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-13
Area Plan, adopted by the County in 2009, provides the framework for the coordination of
management, monitoring, containment, and removal of hazardous materials for County regulatory
and response agencies.
Contra Costa County Office of the Sheriff
The Sheriff’s Office of Emergency Services has overall responsibility for implementation of the
Emergency Operations Plan (EOP), under the direction of the County Administrator. The purpose of
the EOP is to provide the basis for a coordinated response before, during and after an emergency
affecting the County (Contra Costa County 2015). The EOP applies to all emergencies in
unincorporated areas of the County and that generate situations requiring planned, coordinated
responses. The EOP also applies to emergencies that occur within incorporated areas, to the extent that
those emergencies require multi-agency coordination at the operational area level. Potential
emergencies include hazardous materials spills and wildfire.
Contra Costa County Hazard Mitigation Plan Update
The federal Disaster Mitigation Act of 2000 required state and local governments to develop
Hazard Mitigation Plans (HMPs) as a condition for federal disaster grant assistance. The County
participated in an effort led by the Association of Bay Area Governments in 2004 to meet this
requirement. The County adopted an update of that HMP in 2011 that completely restructured the
plan as a countywide plan focused on the County (as opposed to the previous multicounty plan).
The plan, in compliance with federal requirements, includes a description of the planning process,
a risk assessment, a mitigation strategy (goals, alternatives, and a prioritized action plan), a plan
maintenance section, and documentation of plan adoption (Contra Costa County 2011). The
County HMP also includes a second volume that includes the various special districts within the
County as planning partners.
3.7.3 Thresholds of Significance
The significance criteria used to evaluate the project impacts related to hazards and hazardous
materials are based on Appendix G of the CEQA Guidelines. According to Appendix G of the
CEQA Guidelines, a significant impact related to hazards and hazardous material would occur if
the project would:
1. Create a significant hazard to the public or the environment through the routine transport,
use, or disposal of hazardous materials.
2. 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.
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-14
3. Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances,
or waste within one-quarter mile of an existing or proposed school.
4. 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 result, would it create a significant
hazard to the public or the environment.
5. 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.
6. Impair implementation of or physically interfere with an adopted emergency response plan
or emergency evacuation plan.
In addition, this chapter addresses the wildfire issues in Appendix G of the CEQA Guidelines. A
significant effect may result if the project is located in or near SRAs or lands classified as very
high fire hazard severity zones, and would:
7. 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.
8. 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.
9. 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?
Regarding item 5, the project site is located on public airport land with an airport land use plan.
As part of the proposed project, the airport land use plan would be updated to reflect recent
regulatory guidance and the most recent airport layout plan. The project incorporates safety
considerations for people working on the airport and residing or working in the airport vicinity.
See Chapter 2 and Section 3.9, Land Use and Planning, for discussion of this issue.
3.7.4 Impacts Analysis
Impact 3.7-1. The project would not create a significant hazard to the public or the
environment through the routine transport, use, or disposal of hazardous
materials. (Less than Significant)
Hazardous materials used and stored on the project site include aviation fuel, gasoline, diesel,
waste oil, and detergents. While the number of airport operations is forecast to increase, the type
of activities would be similar to existing uses. Future aviation operations at the project site would
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-15
therefore involve similar storage, use, and disposal of fuel and oil. These hazardous materials
would be safely managed in accordance with local, state, and federal regulations.
As the quantities of hazardous materials handled by the airport currently and would likely still
equal or exceed 55 gallons of liquid, 500 pounds of solids, and/or 200 cubic feet of a compressed
gas at any time, an HMBP would be prepared/updated for the project site and submitted to the
Certified Unified Program Agency via the California Environmental Reporting System. The
HMBP would include an inventory of hazardous materials, present a site map identifying locations
of hazardous materials and safety equipment, and address preparedness for emergency response to
incidents involving hazardous materials.
Likewise, as the project site involves the aboveground storage of an aggregate quantity of 1,320
gallons or more of petroleum or petroleum products, a Spill Prevention Control and
Countermeasure Plan would be prepared/updated and implemented.
Accumulation, management, and disposal of hazardous waste is regulated by the California
Department of Toxic Substances Control and the EPA. Under federal regulation (RCRA), waste is
classified as hazardous based on the process that generated the listed waste or its characteristics of
ignitibility, reactivity, corrosion and/or toxicity. California mandates further criteria for hazardous
waste in addition to those established under the RCRA. Waste accumulation is regulated based on the
quantities produced and the distance to the nearest treatment, storage, and disposal facility.
Once classified as hazardous, waste would not accumulate longer than 90 days for large quantity
generators and 180 days (or 270 days if the distance to the treatment, storage, and disposal facility
is more than 200 miles) for small quantity generators. These accumulation times begin as soon as
the waste begins accumulating. For a Conditionally Exempt Small Quantity Generator, hazardous
waste can accumulate for 180 days (or 270 days if the distance to the treatment, storage, and
disposal facility is more than 200 miles) once 100 kg of hazardous waste has accumulated. Waste
considered acutely or extremely hazardous must be removed within 90 days for small quantity
generators and Conditionally Exempt Small Quantity Generators. Hazardous and non-hazardous
waste would be stored, labeled, and manifested in accordance with state and federal regulations,
including those summarized in the Hazardous Waste Generator Requirements. Waste oil, which is
currently generated at the airport and would likely continue to be generated, is the only California-
hazardous waste anticipated for the project site.
Airport fueling would be completed in accordance with general standards for airport fueling
operations, as presented in the 2015 Airport Cooperative Research Program Synthesis 63,
Overview of Airport Fueling System Operations.
Development of non-aviation uses, including light industrial, warehousing, commercial, and office
uses, may also result in the routine use and storage of hazardous materials. These materials may
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-16
include solvents, paints, waste oil, and other petroleum products. As described above, if these
materials are stored in sufficient quantities on site, an HMBP and/or Spill Prevention Control and
Countermeasure Plan would be completed.
In conclusion, routine transport, use, and disposal of hazardous materials associated with the
proposed project would be completed in accordance with applicable federal, state, and local
regulations. Therefore, impacts would be less than significant.
Impact 3.7-2. The project has the potential to create a significant hazard to the public
or the environment thro ugh reasonably foreseeable upset and accident
conditions involving the release of hazardous materials into the
environment . (Potentially Significant)
As described in the Existing Conditions, Section 3.7-1, there are three abandoned oil and gas wells
located within the Airport Boundary, near Byron Hot Springs Road. These wells are located within
the proposed Habitat Management Area; development is not anticipated or proposed within this
area. The closest well to a proposed development area is approximately 0.4 miles to the southeast;
the other two wells are approximately 0.5 miles southeast of the development area. While the wells
have not been abandoned in accordance with current rules and regulations, development is not
proposed in this area, and the wells will therefore not be impacted by the project. Therefore the
impact to the existing wells would be less than significant. If, in the future, non-project activities
disturb or otherwise impact these wells, abandonment would be required in accordance with Public
Resources Code (PRC) Section 3208.1. As defined in PRC 3208.1, either the property owner or
the party building over or otherwise disturbing the integrity of the abandoned well would be
responsible for the abandonment. Compliance with applicable rules and regulations would avoid
any adverse environmental effects.
While there have been no known releases to the subsurface causing contamination (there have
been minor releases from drums and a fuel release to the surface that was cleaned up), it is possible
that subsurface releases/contamination have occurred in areas of fuel/oil storage and use (areas
near the ASTs, wash rack, oil/water separator[s], crude oil pipeline, leach field, former fuel islands,
and potential USTs) (Figure 3.7-1). Construction activities in these areas could result in
encountering contaminated soil and/or groundwater. Exposure of contaminated soils to workers
and the surrounding environment would result in potentially significant impacts. Mitigation
Measure (MM) HAZ-1 would require the preparation of a Hazardous Materials Contingency Plan.
While potential oil and fuel releases can be identified during construction using visual and odor
indicators and air monitoring, potential pesticide impacts are not easily identified during
construction. As discussed in the Section 3.7.1, Existing Conditions, based on a review of historical
aerial photographs, it appears that an area in the eastern portion of the project site was used for
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-17
agriculture from the 1960s until the 1980s. Pesticides may have been used at the project site during
this time. Exposure of pesticide-contaminated soils to workers and the surrounding environment
during grading and construction would result in potentially significant impacts. MM HAZ-2
requires soil sampling, analysis, and potential remediation of soils in this former agricultural area.
Impact 3.7-3. The project would not emit hazardous emissions or handle hazardous or
acutely hazardous materials, substances, or waste within one-quarter mile of
an existing or proposed school. (No Impact)
All existing nearby schools are more than 0.25 miles from the project site. The closest schools to
the project site (at the closest point) include Byron Elementary (3.2 miles north), Vista Oaks
Charter (3.3 miles north), Delta Vista High School (3.1 miles north), Mountain House Elementary
(4.1 miles southeast), Altamont Elementary (5.4 miles southeast), Bethany Elementary (5.9 miles
southeast), Wicklund Elementary (6.3 miles southeast), Julius Cordes School (6.7 miles southeast),
Hansen Elementary (6.3 miles southeast), and Mountain House High School (6.4 miles southeast).
The proposed project would not include any operations that would emit hazardous emissions or
handle hazardous or acutely hazardous materials, substances, or waste within 0.25 miles of an
existing or proposed school. Therefore, the proposed project would have no impact.
Impact 3.7-4. The project would not be located on a site included on a list of hazardous
materials sites compiled pursuant to Government Code Section 65962.5 that
would potentially result in a significant hazard to the public or the
environment. (No Impact).
The EDR search conducted for the project site did not identify the presence of sites compiled
pursuant to Government Code Section 65962.5 (also known as the Cortese List). The disturbance
of previously unlisted contaminated areas from project activities is addressed in Impact 3.7-2.
There would be no impact related to hazardous materials sites included on the Cortese List.
Impact 3.7-5. The project would not impair implementation of or physically interfere with
an adopted emergency response plan or emergency evacuation plan. (Less
than Significant)
The project would not interfere with an adopted emergency response or evacuation plan. The EOP
and HMP do not identify specific criteria or evacuation routes that apply to the airport. Local roads
serving the airport currently meet the minimum requirements for two-way access (10-foot travel
lanes). However, expansion of airport-related uses at the airport would require roadway
improvements (Section 3.13, Transportation). This would result in long-term access
improvements. Construction activities may result in short-term lane closures, but any lane closures
due to construction activity would be coordinated with emergency service providers to maintain
access. Access to the airport and surrounding properties would be maintained throughout
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-18
construction. The project impact associated with impairing implementation of or physically
interfering with the adopted emergency evacuation plan would be less than significant.
Impact 3.7-6. The project would not, due to slope, prevailing winds, and other factors,
exacerbate wildfire risks, and thereby expose project occupants to, pollutant
concentrations from a wildfire or the uncontrolled spread of a wildfire. (Less
than Significant)
As discussed in Section 3.12, Public Services, fire protection for the project vicinity is provided
by the East Contra Costa Fire Protection District and the airport provides fire protection for
aviation activities. The closest fire station to the project site is East Contra Costa Fire Station 59
located approximately 5.7 miles north of the site. The East Contra Costa Fire Protection District
enforces the County’s current Fire Code, which provides strict requirements for fire suppression
systems, use of fire-resistant building materials, and visible address signage.
The project area is not located in a High or Very High Fire Hazard Severity Zone. The project site
is partially located within an SRA, with a moderate fire hazard severity risk. The project would
not introduce residential uses. Non-residential structures at the project, due to being within an
SRA, would comply with state requirements for access/egress, signage, and defensible space
(including fuel management).
The project would not exacerbate wildfire risks due to slope, prevailing winds, and other factors,
and thereby expose project occupants to pollutant concentrations from a wildfire or the
uncontrolled spread of a wildfire. The project site is relatively flat, with hills rising to the west.
The development areas within the project site are primarily agricultural or vacant/ruderal
grasslands. The prevailing wind direction varies. During the summer, strong afternoon winds from
the west may occur (see Section 3.2, Air Quality). For these reasons, the project site is identified
as moderate for fire hazard severity. The project would not introduce residences or vegetation that
would exacerbate this risk. This impact would be less than significant.
Impact 3.7-7. The project would not require the installation or maintenance of associated
infrastructure (such as roads, fuel breaks, emergency water sources, power
lines or other utilities) that may exacerbate fire risk or that may result in
temporary or ongoing impacts to the environment. (Less than Significant)
The project would require the installation of infrastructure (e.g., roadway improvements, water
supply improvements, sewer facilities). These facilities would not exacerbate fire risk, and
improved roadways and water infrastructure may be a beneficial impact for wildfire risk. This
impact would be less than significant.
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-19
Impact 3.7-8. The project would not expose people or structures to significant risks,
including downslope or downstream flooding or landslides, as a result of
runoff, post-fire slope instability, or drainage changes. (Less than Significant)
The project would not expose people or structures to secondary impacts of wildfire, including
downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or
drainage changes. As discussed, the project site is relatively flat and not subject to landslides. Flooding
risk is limited to a small area in the northeast corner of the project associated with Brushy Creek. This
impact would be less than significant.
3.7.5 Mitigation Measures
MM-HAZ-1 Prior to initiation of grading and construction, a Hazardous Materials Contingency
Plan shall be in-place and consist of the following:
• Identification of areas of potential fuel- or oil-impacted soils on a site plan.
• Protocol for identifying suspected contaminated soils (e.g., discoloring,
odor, positive photoionization detector readings), utilizing personnel
trained in recognition of contaminated soils/groundwater and certified with
respect to Occupational Safety and Health Administration Hazardous Waste
Operations and Emergency Response (i.e., OSHA HAZWOPER training).
• Procedures for notification and reporting, including internal management and
to Contra Costa Environmental Health Division and local agencies, as needed.
• Procedures for temporary cessation of construction activity and evaluation
of the level of environmental concern.
• Procedures for limiting access to the contaminated area to personnel with
OSHA HAZWOPER training.
• A worker health and safety plan for excavation of contaminated soil
and/or groundwater.
• Procedures for characterizing, managing, and disposing of potentially
contaminated soils.
MM-HAZ-2 Prior to development of the former agricultural areas identified in Figure 3.7-1,
Hazards Site Map, soil samples shall be collected and tested for pesticides. Shallow
soil samples shall be collected from the upper 0.5 to 1.0 foot of ground surface and
analyzed for organochlorine pesticides by U.S. Environmental Protection Agency
(EPA) Method 8081A and arsenic by EPA Method 6010B. The soil samples shall
3.7 – HAZARDS AND HAZARDOUS MATERIALS
Byron Airport Development Program EIR 9269
February 2022 3.7-20
be analyzed by a California Environmental Laboratory Accreditation Program-
certified laboratory.
The pesticide sampling data shall be compared to applicable regulatory threshold
levels such as the EPA Regional Screening Levels and the Department of Toxic
Substances Control Human and Ecological Risk Office Note 3 screening levels.
The arsenic sampling data shall be compared to California typical background
levels, such as those in the 1996 Kearney Foundation Special Report on
Background Concentrations of Trace and Major Elements in California Soils.
If the soil sampling concentrations, using the 95% upper confidence level or other
statistical evaluation, exceed the screening level, mitigation shall include removal
of impacted soil for off-site disposal prior to or during construction grading. A soil
management plan, including a health and safety plan, shall be prepared to properly
manage the excavated soil and protect worker and public health and safety.
3.7.6 Level of Significance After Mitigation
MM-HAZ-1 would require a Hazardous Materials Contingency Plan to address any accidental
discovery of contaminated soils or groundwater during project construction. The procedures would
protect workers and members of the public from hazardous materials impacts. A related mitigation
measure, MM-HAZ-2, would require sampling of soils in former agricultural areas, and if pesticide
levels exceed health standards, remediation would be required. With implementation of the
identified mitigation measures, Impact 3.7-2 would be reduced to less than significant.
3.7.7 Cumulative Impacts
The cumulative analysis for hazards and hazardous materials is based on development considered
in the County General Plan. The vicinity of the project site is primarily designated for agricultural
use. Although agricultural operations may involve the use of pesticides and petroleum products
(for vehicles and equipment), such uses would not be of a type or quantity that would interact with
the proposed project to produce cumulative effects. The Hazards Assessment prepared in support
of this EIR (Appendix G) identifies hazardous materials storage, use, and release sites on and near
the project site. The potential project–related effects related to these sites are addressed in the
impact analysis, Section 3.7.4. No future development identified in the General Plan would affect
these sites in a manner that would create a cumulative impact. In addition, compliance with
existing regulations and with MM-HAZ-1 and MM-HAZ-2 would reduce any project contribution
to potential cumulative impacts to less than significant.

3.8 HYDROLOGY AND WATER QUALITY
This section describes the existing hydrology and water quality of the Byron Airport Development
Program (project) site, identifies associated regulatory requirements, evaluates potential impacts,
and identifies mitigation measures to reduce the proposed project’s potentially significant impacts
to less-than-significant levels. In response to the Notice of Preparation, the Central Valley
Regional Water Quality Control Board (RWQCB) sent a letter listing the regulatory framework
potentially applicable to the site; applicable regulations are described in Section 3.8.2, Relevant
Plans, Policies, and Ordinances.
3.8.1 Existing Conditions
3.8.1.1 Watersheds
Regionally, watersheds within the project site are identified based on the U.S. Geological Survey
(USGS) Watershed Boundary Dataset (USGS 2018). The Watershed Boundary Dataset delineates
watersheds according to hydrologic units (HUs), which are nested within one another according
to the scale of interest. USGS identifies HUs by name and by hydrologic unit code (HUC), which
gets longer as the watershed boundaries are delineated at a finer scale (i.e., more detailed). For
example, at a statewide scale, HUs consist of large regions and subregions draining to a common
outlet. At this scale, the project site is within the 1,232-square-mile San Joaquin Delta Subbasin
(HUC 18040003), whose outlet point is the Sacramento-San Joaquin Delta and the San Francisco
Bay. These watershed areas are listed in Table 3.8-1.

The project site crosses several subwatershed boundaries within the 243-square-mile Old River
Watershed (HUC 1804000306) (USGS 2018). Figure 3.8-1 shows the creeks and subwatersheds that
occur within the Byron Airport property and the proposed development area (i.e., aviation and non-
aviation uses). The development area boundary is largely within the 16-square-mile Brushy Creek
subwatershed (HUC 180400030603), although a small part of the southeastern portion of the
development area is within the 104-square-mile Lower Old River subwatershed. The southeastern part
of the airport property lies within the 25-square-mile Clifton Court Forebay subwatershed.

In managing water resources, the State Water Resources Control Board (SWRCB) classifies
watersheds in a hierarchical system similar to the USGS Watershed Boundary Dataset, but with
watershed names and boundaries that are designated by the California Department of Water
Resources (DWR). These geographic boundaries are likewise watershed based, but are typically
referred to as hydrologic basins and are defined in the Water Quality Control Plan for the California
Regional Water Quality Control Board, Central Valley: Sacramento River Basin and San Joaquin
River Basin (Basin Plan) (Central Valley RWQCB 2015).1 These generally constitute the
geographic basis around which many surface water quality problems and goals/objectives are
defined, and consist of surface water HUs, hydrologic areas, and hydrologic subareas. The project
site is partially within the North Diablo Range HU (HU 543.00) and partially within San Joaquin
Delta HU (HU 544.00) (Central Valley RWQCB 2015). The Basin Plan does not designate
hydrologic areas or subareas for the project site (Central Valley RWQCB 2015).
3.8.1.2 Surface Water Features and Drainage Patterns
The project site ranges in elevation from 30 feet above mean sea level near the intersection of
Holey Road and Byron Hot Springs Road to 125 feet above mean sea level in the middle part of
the site’s western boundary (Google Earth 2018). The airport reference elevation is 76 feet above
mean sea level. Elevations on site generally decrease from southwest to northeast. Stormwater
drainage is generally expected to flow in a similar direction, and/or toward Brushy Creek in the
central, northern, and western portions of the site and toward the unnamed ephemeral drainage in
the southeastern part of the site.
Brushy Creek is the primary natural waterway that crosses the project site (Figure 3.8-1). Brushy
Creek starts in Alameda County near the eastern flank of Brushy Peak and flows to the north.
Several unnamed spring-fed streams converge with Brushy Creek north of the Contra
Costa/Alameda County line. The lower reach of Brushy Creek enters the alluvial plain near the
Byron Airport. East of the northern border of the airport, Brushy Creek confluences with Indian
Slough, which in turn confluences with Old River, before joining the Sacramento-San Joaquin
Delta (USGS 2018).
Brushy Creek enters the southwestern part of the airport property where it under-crosses
Armstrong Road, flows north-northeast to a marshy flat area south of the airport’s main access
road (Falcon Way), under-crosses Falcon Way through a culvert, snakes between the skydiving
operation to the west and the western end of Runway 12-30 to the east, and exits the northern
border of the site under Armstrong Road. Brushy Creek is classified by the USGS as a perennial
stream upstream of its first crossing of Armstrong Road, and an intermittent (i.e., seasonal) stream
1 The Basin Plan for each region serves as the regulatory reference for meeting both state and federal requirements
for water quality control. It designates beneficial uses to be protected, water quality objectives to pr otect those
uses, and a program of implementation needed for achieving those objectives.

downstream of Armstrong Road (within the project site) (USGS 2018). Flow in Brushy Creek
slows to a trickle or subsurface flow during the late summer and early fall seasons. Based on review
of aerial photography and topography, Brushy Creek appears to be quite deeply entrenched within
the alluvial plain. East of the airport, Brushy Creek enters Italian Slough, which meanders north
along the western perimeter of Clifton Court Forebay, toward Old River.
Although Brushy Creek crosses the airport property, the primary receiving water for the existing
and proposed development footprint of the project is an approximately 15-acre detention basin
located southeast of Runway 12-30 and east of Runway 5-23 (Google Earth 2018; LFA 2005).
This basin, along with a system of drainage ditches and stormwater pipes designed for a 10 -year
storm, collects runoff from the majority of the developed portions of the project site (Figure 3.8-
2, Site Drainage) (Mead and Hunt 2013). The existing aviation uses (administration building,
aircraft and vehicle parking, hangar spaces, maintenance warehouses, pump house, wash rack, and
other ancillary structures) are graded to drain northeast toward Runway 12-30 and its taxiway,
which, through pipes and ditches, direct storm flows to the southeast and eventually to the
detention basin (Figure 3.8-2) (LFA 2005). Runway 5-23 and its taxiway direct storm flows to the
east-northeast, also to the detention basin (LFA 2005). Aside from the northern edge of the
proposed airport related uses adjacent to Brushy Creek, drainage for the proposed aviation and
non-aviation uses would be similarly directed toward the detention basin (Figure 3.8-2). Under
normal circumstances, storm flow that is collected by the detention basin is either lost to
evaporation and/or percolates into the underlying groundwater table. During extreme storm events
(e.g., greater than a 10-year storm), when the detention basin reaches its holding capacity, it is
designed to overflow into a ditch that flows north under Holey Road and then northeast to the
lower-most reach of Brushy Creek near Byron Highway approximately 0.5 miles upstream of its
confluence with Indian Slough (Google Earth 2018; LFA 2005; USGS 2018).
Besides the detention basin and Brushy Creek, there are several other surface water features within
the project site. A minor ephemeral drainage ditch flows northeasterly in the southeast corner of
the site between Byron Hot Springs Road and North Bruns Way, appearing to terminate at a 4-
acre irrigation and/or cattle pond (USGS 2018; Google Earth 2018). This area would remain as
habitat management land. In addition, Canal 45 crosses the project site along the northeastern edge
of Runway 12-30 (BBID 2017). Canal 45 is the northern extension of the Byron-Bethany Irrigation
District and is supplied with water during the irrigation season through a pump station on the north
side of the California Aqueduct (BBID 2017). A portion of this canal northwest of Byron Hot
Springs Road to north of the airport detention basin is routed underground (LFA 2005; Google
Earth 2018). In addition, a small 0.4-acre pond with an estimated 750,000-gallon capacity was
constructed southeast of the intersection of Holey Road and Byron Hot Springs Road for the
purpose of storing water for fire protection (Mead and Hunt 2013). Water for this pond is supplied
by the Byron-Bethany Irrigation District through a pump located above the underground portion
of Canal 45 (Mead and Hunt 2013; LFA 2005).

Clifton Court Forebay is located less than 2 miles east of the site, Bethany Reservoir is
approximately 3 miles to the south, and Los Vaqueros Reservoir is 5 miles to the west.
3.8.1.3 Flood Hazard
Flood zones identified on Federal Emergency Management Agency (FEMA) Flood Insurance Rate
Maps (FIRMs) are identified as a Special Flood Hazard Area (SFHA). An SFHA is defined as the
area that will be inundated by the flood event having a 1% chance of being equaled or exceeded
in any given year. The 1%-annual-chance flood is also referred to as the base flood or 100-year
flood. “Floodways” are areas within the SFHA that include the channel of a river/watercourse and
adjacent land areas which in an unobstructed condition can discharge a 100-year flood/base flood
without any increase in water surface elevations. The area outside the floodway but still within the
100-year floodplain can be obstructed without increasing the water surface elevation of a 100-year
flood event more than 1 foot at any point.
According to the FEMA, there is an SFHA associated with Brushy Creek (FEMA 2017). FEMA
has mapped SFHAs on the project site on FIRM panel numbers 06013C0510G and 06013C0530G
(effective March 21, 2017), shown in Figure 3.8-2. The flood zone widens significantly along
Brushy Creek in an area located west of Runway 12-30 and west of Falcon Way, and spreads over
low-lying areas between the two runways and south of Runway 5-23. The flood zone crosses
Falcon Way near its intersection with Armstrong Road and crosses the northeastern end of Runway
5-23. Review of the flood zone shows that it is largely confined to areas of the project site that
would be designated as habitat management or low intensity use. However, the flood zone
intersects an area designated for airport-related uses just south of Armstrong Road, northwest of
Runway 12-30 (FEMA 2017). Also shown in Figure 3.8-2 is a regulatory floodway2 along Brushy
Creek, which intersects the northern edge of the proposed development area for airport-related
uses. In addition, the 100-year flood hazard area terminates at the airport’s 15-acre detention basin
located southeast of Runway 12-30 and east of Runway 5-23. East of the detention basin, a 500-
year hazard area (also referred to as a 0.2%-annual-chance flood hazard) is mapped by FEMA.
3.8.1.4 Groundwater Resources
The entire project site is located within the Tracy Groundwater Subbasin3 of the San Joaquin
Valley Groundwater Basin (DWR Basin No. 5-022.15), as defined by DWR (DWR 2003). The
Great Valley is a broad structural trough bounded by the tilted block of the Sierra Nevada on the
east and the complexly folded and faulted Coast Ranges on the west. The Tracy Subbasin is defined
by the areal extent of unconsolidated to semi-consolidated sedimentary deposits that are bounded
2 FEMA regulates filling and construction in floodways to allow flood waters to be discharged without raising
surface water levels beyond a designated height.
3 The California Department of Water Resources is currently reviewing a request to rename the Subbasin to the
“East Contra Costa County Subbasin.”
3.8 – HYDROLOGY AND WATER QUALITY

February 2022 3.8-5
by the Diablo Range on the west, Mokelumne and San Joaquin Rivers on the north, San Joaquin
River to the east, and San Joaquin/Stanislaus County line on the south (DWR 2003). Water-bearing
formations consist of continental deposits of Late Tertiary to Quaternary age, and the cumulative
thickness of these deposits increases from a few hundred feet near the Coast Range foothills on
the west to about 3,000 feet along the eastern margin of the basin (DWR 2003). Given the project
site is on the western edge of the subbasin, it is likely that basin deposits are on the low end of the
range of thickness. Annual precipitation within the subbasin ranges from about 11 inches in the
south to about 16 inches in the north (DWR 200 3). DWR reports that groundwater yields in the
Tracy Subbasin range from 500 to 3,000 gallons per minute when isolating the yields obtained by
municipal wells.
Limited current information is available regarding groundwater levels and quality on site and in
the project area. However, DWR well completion reports and the USGS national water information
system were reviewed for groundwater level information pertaining to the project site and its
vicinity. Table 3.8-2 shows well completion report records available for each township and range
section that intersects or shares a border with Byron Airport, including information on the average
depth of wells and the range of depths. The well types are primarily domestic wells but include
three larger production and/or irrigation wells. Based on review of well completion reports,
groundwater levels in the local vicinity, as reported when the wells were first drilled, have
historically varied between 10 and 100 feet below ground surface (DWR 2018a). However, the
majority of records reviewed reported a groundwater level of between 10 and 30 feet below ground
surface (DWR 2018a). Well yields, where recorded in well completion reports, were generally
low. The on-site well used to supply the project site is reported to yield 1 gallon per minute or less
(40–60 gallons per hour) (Mead and Hunt 2013).
Except for seasonal variation resulting from recharge and pumping, the majority of water levels in
wells have remained relatively stable over at least the last 10 years (DWR 2003). Long-term water
level records for two off-site wells are available, one located 1 mile east of the site’s southeastern
boundary adjacent to the California Aqueduct (State Well No. 01S03E25M999M), and one located
about 0.75 miles north of the site’s northern boundary (State Well No. 01S03E15A001M) (DWR
2018b). Groundwater levels recorded at State Well No. 01S03E25M999M have generally been
stable within the period of record from July 2014 to March 2018, and have ranged from 5 to 14
feet below ground surface (DWR 2018b). Groundwater levels recorded at State Well No.
01S03E15A001M have also been fairly stable within the period of record from October 1974 to
April 2018, and have ranged from 2 to 12 feet below ground surface (DWR 2018b). As these wells
are at lower elevations and located further away from the east flank of the Diablo Range, they have
somewhat shallower groundwater levels than are likely to be encountered on the project site but
are still likely to be representative of overall trends in groundwater table elevation. The
groundwater elevation may fluctuate due to seasonal variation in rainfall, irrigation, tidal action,
pumping rates, or other factors not evident at the time of exploration.

3.8.1.5 Water Quality
Perhaps due to the intermittent and ephemeral nature of the waterways located on site, very limited
surface water quality data are available for the project site and its vicinity. Brushy Creek is not
included in the Clean Water Act (CWA) Section 303(d) list of water quality impaired segments
for California (SWRCB 2018) (Table 3.8-3). Being impaired (also known as “water quality-
limited”) means that a water body is “not reasonably expected to attain or maintain water quality
standards” without additional regulation. The CWA requires that the U.S. Environmental
Protection Agency (EPA) develop total maximum daily loads (TMDLs) for each impaired water
body in the nation (described further below in Section 3.8.2). The TMDLs specify the maximum
amount of a pollutant a water body can receive and still meet water quality standards. A TMDL
may also include a plan for bringing an impaired water body within standards.
Substantial water quality data are available for the Sacramento-San Joaquin Delta, of which
Brushy Creek and Old River are tributaries. Old River has the following impairments: low
dissolved oxygen, chlorpyrifos, total dissolved solids (TDS), and electrical conductivity (SWRCB
2018). Sacramento-San Joaquin Delta waters are included on the CWA Section 303(d) list for the
following constituents: toxicity, diazinon, DDT, Group A pesticides, electrical conductivity, TDS,
mercury, and chlorpyrifos (SWRCB 2018). TMDLs have been approved for chlorpyrifos and
diazinon, both of which are pesticides that are no longer used, as well as for mercury, which is
present in waterways as a result of the state’s history with hydraulic gold mining.

Groundwater quality is reported from several sources to be generally poor or undesirable. In
general, the northern part of the Tracy Groundwater Subbasin, in which the project site is located,
is characterized by a sodium water type and a wide range of anionic water types including
bicarbonate, chloride, and mixed bicarbonate-chloride types (DWR 2003). Based on analyses of
36 water supply wells in the subbasin, TDS range from 210 to 7,800 milligram per liter and
averages about 1,190 milligram per liter (DWR 2003). TDS is a general measure of water quality
and high levels, generally above 500 milligram per liter, are considered undesirable and exceed
secondary maximum contaminant levels. In addition, elevated levels of chloride, nitrate, and boron
have been measured in the subbasin (DWR 2003). Mead and Hunt (2013) report that the on-site
groundwater well was tested when originally constructed, prior to development, and had a TDS
concentration of 13,000 milligram per liter, which is not suitable for potable use.
This information indicates that groundwater for potable (drinking) use would require treatment to
meet potable water quality standards. The on-site well used by the airport does not produce raw
water of suitable quality for drinking, and currently can only be used for non-potable purposes
(e.g., aircraft wash water and grounds maintenance).
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-8
3.8.1.6 Tsunamis and Seiches
Tsunamis are earthquake-generated displacements of water resulting in a rise or mounding at the
ocean surface that moves away from the center as a sea wave. All portions of the project site are
located at least several hundred feet above sea level, within landlocked areas that are not adjacent
to the ocean or other water bodies that would support the propagation of a tsunami.
Seiches are large-scale waves of long wave length in a closed body of water such as a lake or
reservoir. They can be caused by earthquake shaking or a landslide along the shore of a lake or
reservoir. There are no lakes or reservoirs on or directly adjacent to the project site. As these water
bodies are 2 to 5 miles from the project site, the project site is not subject to risk from a seiche.
3.8.1.7 Dam Inundation
As identified in Section 3.8.1.6, above, there are essentially three reservoirs in the project vicinity:
Clifton Court Forebay less than 2 miles east of the site, Bethany Reservoir approximately 3 miles
to the south, and Los Vaqueros Reservoir 5 miles to the west. The Department of Water Resources,
Division of Dam Safety, maintains dam inundation maps that show areas that would be impacted
by a dam failure. Los Vaqueros has the largest inundation of the three and would affect the
communities of Byron and Discovery Bay. However, the project site is not within the inundation
area (DWR 2021a). Clifton Forebay and Bethany Reservoir have smaller inundation areas which
would not affect the project site (DWR 2021b).
3.8.2 Relevant Plans, Policies, and Ordinances
The regulatory framework related to hydrology and water quality is extensive because it addresses
issues related to the environment (i.e., maintaining high quality waters for water-dependent species
and activities), public health (e.g., ensuring adequate drinking water quality), and public safety (e.g.,
avoiding flood damage). Impacts pertaining to provision of potable and non-potable water supplies,
including applicable regulations, are addressed in Section 3.14, Utilities. Additional background and
details on water supply, specifically compliance with Senate Bill (SB) 610, is provided in the Water
Supply Assessment, included as Appendix I of this Environmental Impact Report.
Federal
Clean Water Act
The CWA, as amended by the Water Quality Act of 1987, is the major federal legislation governing
water quality (33 USC 1251 et seq.). The objective of the CWA is “to restore and maintain the
chemical, physical, and biological integrity of the Nation’s waters.” The CWA establishes basic
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-9
guidelines for regulating discharges of both point and non-point sources4 of pollutants into the
waters of the United States. The CWA requires that states adopt water quality standards to protect
public health, enhance the quality of water resources, and ensure implementation of the CWA.
Relevant sections of the act are as follows:
• Sections 303 and 304 provide for water quality standards, criteria, and guidelines. Under
Section 303(d) of the CWA, the State of California is required to develop a list of impaired
water bodies that do not meet water quality standards and objectives. California is required
to establish TMDLs for each pollutant/stressor. A TMDL defines how much of a specific
pollutant/stressor a given water body can tolerate and still meet relevant water quality
standards. Once a water body is placed on the Section 303(d) List of Water Quality Limited
Segments, it remains on the list until a TMDL is adopted and the water quality standards
are attained, or there is sufficient data to demonstrate that water quality standards have
been met and delisting from the Section 303(d) list should take place. The water quality
impairments relevant to the project are shown in Table 3.8-3, and the basin planning
process that establishes beneficial uses and associated water quality objectives are further
described under the heading Water Quality Control Plan for the Sacramento River Basin
and San Joaquin River Basin below.
• Section 401 (Water Quality Certification) requires an applicant for any federal permit
that proposes an activity which may result in a discharge to waters of the United States to
obtain certification from the state that the discharge will comply with other provisions of
the CWA. This process is known as the Water Quality Certification/waste discharge
requirements (WDRs) process. For projects in southeastern Contra Costa County (County),
the Central Valley RWQCB issues CWA Section 401 permits.
• Section 402 (National Pollutant Discharge Elimination System) establishes the National
Pollutant Discharge Elimination System (NPDES), a permitting system for the discharge
of any pollutant (except for dredged or fill material) into waters of the United States. This
permit program is administered by the SWRCB and the nine RWQCBs, who have several
programs that implement individual and general permits related to construction activit ies,
stormwater runoff quality, and various kinds of non-stormwater discharges.
• Section 404 (Discharge of Dredged or Fill Material into Waters of the United States)
establishes a permit program for the discharge of dredged or fill material into waters of the
United States. This permit program is jointly administered by the U.S. Army Corps of
Engineers and EPA. Environmental Impact Report Section 3.3, Biological Resources,
addresses this impact/requirement in greater detail.
4 Point source discharges are those emanating from a pipe or discrete location/process, such as an industrial proce ss
or wastewater discharge. Non-point source pollutants are those that originate from numerous diffuse sources and
land uses, and which can accumulate in stormwater runoff or in groundwater.
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-10
Numerous agencies have responsib ilities for administration and enforcement of the CWA. At
the federal level this includes the EPA, U.S. Army Corps of Engineers, Bureau of Reclamation,
and the major federal land management agencies such as the U.S. Forest Service and Bureau
of Land Management. At the state level, with the exception of tribal lands, the California EPA
and its sub -agencies, including the SWRCB, have been delegated primary responsibility for
administering and enforcing the certain provisions of the CWA in California. At the l ocal level,
the Central Valley RWQCB and the County have both enforcement and implementation
responsibilities under the CWA.
Federal Antidegradation Policy
The federal Antidegradation Policy (40 CFR 131.12) is designed to protect water quality and water
resources. The policy requires states to develop statewide antidegradation policies and identify
methods for implementing them. State antidegradation policies and implementation measures must
include the following provisions: (1) existing instream uses and the water quality necessary to
protect those uses shall be maintained and protected; (2) where existing water quality is better than
necessary to support fishing and swimming conditions, that quality shall be maintained and
protected unless the state finds that allowing lower water quality is necessary for important local
economic or social development; and (3) where high-quality waters constitute an outstanding
national resource, such as waters of national and state parks, wildlife refuges, and waters of
exceptional recreational or ecological significance, that water quality shall be maintained and
protected. State permitting actions must be consistent with the federal Antidegradation Policy.
National Flood Insurance Act
The National Flood Insurance Act of 1968 established the National Flood Insurance Program to
provide flood insurance within communities that would adopt floodplain management programs
to mitigate future flood losses. The act also required the identification of all floodplain areas within
the United States and establishment of flood-risk zones within those areas. FEMA is the primary
agency responsible for administering programs and coordinating with communities to establish
effective floodplain management standards. FEMA is responsible for preparing FIRMs that
delineate the areas of known special flood hazards and their risk applicable to the community.
FEMA FIRMs are used as part of state and community floodplain management regulations, as well
as for insurers to calculate flood insurance premiums. They are also used for emergency
management, land use and water resources planning, and by federal agencies. It is the
responsibility of state and local agencies to implement regulations, ordinances, and policies in
compliance with FEMA requirements to adequately address floodplain management issues and
attempt to prevent loss of life and property, health and safety hazards, and other adverse effects
due to flooding.

The National Flood Insurance Reform Act of 1994 resulted in major changes to the National
Flood Insurance Program . The act provides tools to make the National Flood Insurance
Program more effective in achieving its goals of reducing the risk of flood damag e to properties
and reducing federal expenditures for uninsured properties damaged by flood. The act requires
mitigation insurance and establishes a grant program for state and community flood mitigation
planning projects.
State
Porter–Cologne Water Quality Control Act
The Porter–Cologne Water Quality Control Act (codified in the California Water Code, Section
13000 et seq.) is the primary water quality control law for California. Whereas the CWA applies
to all waters of the United States, the Porter–Cologne Act applies to waters of the state,5 which
includes isolated wetlands and groundwater in addition to federal waters. The act requires a Report
of Waste Discharge for any discharge of waste (liquid, solid, or otherwise) to land or surface waters
that may impair a beneficial use of surface or groundwater of the state. California Water Code
Section 13260(a) requires that any person discharging waste or proposing to discharge waste, other
than to a community sewer system, that could affect the quality of the waters of the state, file a
Report of Waste Discharge with the applicable RWQCB. For discharges directly to surface water
(waters of the United States), an NPDES permit is requir ed, which is issued under both state and
federal law; for other types of discharges, such as waste discharges to land (e.g., spoils disposal
and storage), erosion from soil disturbance, or discharges to waters of the state (e.g., groundwater
and isolated wetlands), WDRs are required and are issued exclusively under state law. WDRs
typically require many of the same best management practices (BMPs) and pollution control
technologies as are required by NPDES-derived permits.
California Antidegradation Policy
The California Antidegradation Policy, otherwise known as the Statement of Policy with Respect
to Maintaining High Quality Water in California, was adopted by the SWRCB (State Board
Resolution No. 68-16) in 1968. Unlike the federal Antidegradation Policy, the California
Antidegradation Policy applies to all waters of the state, not just surface waters. The policy requires
that, with limited exceptions, whenever the existing quality of a water body is better than the
quality established in individual basin plans, such high-quality water must be maintained and
discharges to that water body must not unreasonably affect any present or anticipated beneficial
use of the water resource. As stated in the Basin Plan, “discharge of waste to high quality waters
must apply best practicable treatment or control not only to prevent a condition of pollution or
5 “Waters of the state” are defined in the Porter–Cologne Act as “any surface water or groundwater, including
saline waters, within the boundaries of the state” (California Water Code Section 13050[e]).

the maximum benefit to the people of the State” (Central Valley RWQCB 2015).
Water Quality Control Plan for the Sacramento River Basin and San Joaquin River Basin
The Central Valley RWQCB is responsible for protection of the beneficial uses of waters draining
to the Sacramento-San Joaquin Delta. The Basin Plan designates beneficial uses, establishes water
quality objectives, and contains implementation programs and policies to achieve those objectives
for all waters addressed through the plan (California Water Code Sections 13240–13247) (Central
Valley RWQCB 2015). The most water quality–sensitive beneficial uses applicable to the
Sacramento-San Joaquin Delta include water contact recreation, warm freshwater habitat, cold
freshwater habitat, wildlife habitat, and migration and spawning. The beneficial uses that have the
potential to be affected by the project are shown in Table 3.8-4, and definitions for acronyms are
provided in Table 3.8-5. The Basin Plan also lists groundwater quality objectives for bacteria,
chemical constituents, pesticides, radioactivity, salinity, tastes and odors, and toxicity.

General National Pollutant Discharge Elimination System Permits and Waste
Discharge Requirements
To enable efficient permitting under both the CWA and the Porter–Cologne Act, the SWRCB and
the RWQCBs run permit programs that group similar types of activities that have similar threats
to water quality. These general permit programs include the Phase I Municipal Separate Storm
Sewer System (MS4)6 Permit, the construction general permit, the industrial general permit (IGP),
and other general permits for low-threat discharges. The construction and industrial stormwater
programs are administered by the SWRCB, while the Phase I MS4 Permit and other general WDRs
are administered by the Central Valley RWQCB. Point-source discharges or other activities that
threaten water quality that are not covered under a general permit must seek individual NPDES
permits and/or WDRs, depending on the type, location, and destination of the discharge. For these
types of discharges, the initial step in the process is to submit a Report of Waste Discharge to the
Central Valley RWQCB, who then determines the appropriate permitting pathway.
Table 3.8-6 lists the permits related to water quality that would apply to certain actions conducted
under the project, each of which is further described below.

Construction General Permit (SWRCB Order No. 2009-0009-DWQ, as Amended).
For stormwater discharges associated with construction activity in the State of California, the
SWRCB has adopted the General Permit for Storm Water Discharges Associated with
Construction and Land Disturbance Activities (Construction General Permit) to avoid and
minimize water quality impacts attributable to such activities. The Construction General Permit
applies to all projects in which construction activity disturbs 1 acre or more of soil. Construction
activity subject to this permit includes clearing, grading, and disturbances to the ground, such as
stockpiling and excavation. The Construction General Permit requires development and
implementation of a stormwater pollution prevention plan (SWPPP), which would specify water
quality BMPs designed to reduce or eliminate pollutants in stormwater discharges and authorized
non-stormwater discharges from the construction site. Routine inspection of all BMPs is required
under the provisions of the Construction General Permit, and the SWPPP must be prepared and
implemented by qualified individuals as defined by the SWRCB.
To receive coverage under the Construction General Permit, the project proponent must submit a
Notice of Intent and permit registration documents to the SWRCB. Permit registration documents
include completing a construction site risk assessment to determine appropriate coverage level;
detailed site maps showing disturbance area, drainage area, and BMP types/locations; the SWPPP;
and, where applicable, post-construction water balance calculations and active treatment systems
design documentation.
East Contra Costa County MS4 Permit, Provision C.3 Requirements
(SWRCB Order No. R5-2010-0102, as Amended).
Pursuant to Section 402 of the CWA and the Porter–Cologne Water Quality Control Act, municipal
stormwater discharges in eastern Contra Costa County are regulated under the East Contra Costa
County Municipal NPDES Permit (MS4 Permit), Order No. R5-2010-0102, NPDES Permit No.
CAS083313, adopted September 23, 2010. The most relevant requirement that pertains to the
project is Provision C.3. It should also be noted that the neighboring MS4 permit covering all Bay
Area counties within the boundaries of the San Francisco Bay RWQCB is expected to be amended
in the near future to include the portions of eastern Contra Costa County currently within the
administrative boundaries of the Central Valley RWQCB (Contra Costa Clean Water Program
2018). The current east Contra Costa County MS4 Permit remains in effect until that occurs.
Provision C.3 addresses post-construction stormwater management requirements for new
development and redevelopment projects. This provision applies to a development or
redevelopment project that would create or replace more than 10,000 square feet of impervious
surface or 5,000 square feet for auto service facilities, gas stations, restaurants, and uncovered
parking lots. Currently, the County requires project proponents regulated under the MS4 Permit to
install hydrodynamic devices, or other BMPs, to remove pollutants such as floating liquids and
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-16
solids, trash and debris, and coarse sediment from stormwater runoff, and to show the locations of
such controls on plans submitted with the building permit application. In addition, the County
requires implementation of low-impact development (LID) strategies, preventive source controls,
and additional stormwater treatment measures to minimize the discharge of pollutants in
stormwater runoff and non-stormwater discharge of certain industrial projects, as well as
prevention of increase in runoff flows. The MS4 Permit requires that LID methods shall be the
primary mechanism for implementing such controls.
The required stormwater treatment systems must be designed according to the following hydraulic
sizing criteria:
• Volume Hydraulic Design Basis – Treatment systems whose primary mode of action depends
on volume capacity shall be designed to treat stormwater runoff equal to (a) the maximized
stormwater capture volume for the area, on the basis of historical rainfall records, determined
using the formula and volume capture coefficients set forth in Urban Runoff Quality
Management, Water Environment Federation Manual of Practice No. 23/American Society of
Civil Engineers Manual of Practice No. 87, (1998), pages 175–178 (e.g., approximately the
85th percentile 24-hour storm runoff event); or (b) the volume of annual runoff required to
achieve 80% or more capture, determined in accordance with the methodology set forth in
Section 5 of the California Stormwater Quality Association’s Stormwater Best Management
Practice Handbook, New Development and Redevelopment (2003), using local rainfall data;
• Flow Hydraulic Design Basis – Treatment systems whose primary mode of action depends on
flow capacity shall be sized to treat (a) 10% of the 50-year peak flow rate; (b) the flow of runoff
produced by a rain event equal to at least two times the 85th percentile hourly rainfall intensity
for the applicable area, based on historical records of hourly rainfall depths; or (c) the flow of
runoff resulting from a rain event equal to at least 0.2 inches per hour intensity; or
• Combination Flow and Volume Design Basis – Treatment systems that use a combination
of flow and volume capacity shall be sized to treat at least 80% of the total runoff over the
life of the project, using local rainfall data.
Projects must treat 100% of runoff (based on the selected calculation described above) with LID
treatment measures that include harvesting and reuse, infiltration, evapotranspiration, or
biotreatment (biotreatment may only be used if the other options are infeasible). Biotreatment areas
shall be designed to have a long-term infiltration rate of 5 to 10 inches per hour. The County also
requires development projects to incorporate the following source control and site design measures:
• Minimize stormwater pollutants of concern through measures that may include plumbing
dumpster drips from covered trash, food waste, and compactor enclosures to the sanitary sewer;
• Properly design covers, drains, and storage precautions for outdoor material storage areas
and loading docks;
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-17
• Properly design trash storage areas;
• Minimize stormwater runoff by implementing one or more site design measures, which
include directing roof runoff into cisterns or rain barrels for reuse, or directing roof runoff
to vegetated areas.
The County enforces the requirements of the MS4 Permit through its development review and
permitting process, and thus requires regulated projects to submit a Storm Water Control Plan for
review and approval by the Public Works Department. The Storm Water Control Plan is a separate
document from the SWPPP.
Industrial General Permit (SWRCB Order 2014-0057-DWQ, as Amended).
In California, stormwater discharges from industrial facilities are covered under the NPDES
General Permit for Stormwater Discharges Associated with Industrial Activities (i.e., the IGP).
The IGP is issued by the SWRCB and implemented and enforced by the nine RWQCBs. The IGP
requires implementation of management measures that will achieve the performance standard of
best available technology economically achievable and best conventional pollutant control
technology. The most recent IGP (SWRCB Order No. 2014-0057-DWQ) was adopted April 1,
2014, and became effective on July 1, 2015; it replaces the previous 1997 statewide permit for
industrial stormwater (SWRCB Order No. 2014-0057-DWQ).
The IGP requires stormwater dischargers to eliminate unauthorized non -stormwater discharges,
develop and implement SWPPPs , implement BMPs, conduct monitoring, compare monitoring
results to numeric action levels , perform appropriate exceedance response actions when numeric
action levels are exceeded , and certify and submit all permit registration documents. Changes
under the new IGP compared to the IGP issue d in 1997 are that stormwater dischargers are
required to implement minimum BMPs , electronically file all permit registration documents via
the SWRCB’s Storm Water Multiple Application and Report Tracking System , comply with new
training expectations and roles for qualified industrial stormwater practitioners , sample to detect
exceedance of annual and instantaneous numeric action levels , develop and implement
exceedance response actions if annual or instantaneous numeric action levels are exceeded ,
monitor for parameters listed under CWA Section 303(d), design treatment control BMPs for
flow- and volume-based criteria, and understand new criteria, sampling protocols, and sampling
frequency for qualifying storm events. The new general order also defines desig n storm
standards for treatment control BMPs, qualifying storm events, and sampling protocols to follow
during a design storm event.
As a covered facility, Byron Airport is currently enrolled in the IGP, under waste discharge
identification number 5S07I002606. It is currently operating under an industrial SWPPP and
submits reports to the SWRCB on an annual basis documenting its compliance activities (ACMG
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-18
2016). The airport’s SWPPP is a living document and is updated as needed in concert with
RWQCB requirements and/or changes to facility activities and operations (ACMG 2016). During
qualifying storm events, when discharges are made to the site’s outfall, the airport collects samples
of the flow for testing so that it can verify to the SWRCB that it is not contributing to water quality
impairments or violations of Basin Plan objectives. The annual report also serves to continually
update descriptions of industrial materials and storage/containment devices, and documents
activities undertaken by the airport to keep stormwater facilities and pollution controls working
effectively. Review of the SWRCB’s Storm Water Multiple Application and Report Tracking
System indicates that the facility has never been in violation of permit conditions since adoption
of the 2014 IGP (SWRCB 2019).
General Order for Dewatering and Other Low-Threat Discharges to Surface Waters (Central
Valley RWQCB Order R5-2013-0074, as Amended).
The Central Valley RWQCB has adopted a general NPDES permit for short-term discharges of
small volumes of wastewater from certain construction-related activities. Discharges may be
covered by the permit provided they are either (1) 4 months or less in duration or (2) the average
dry weather discharge does not exceed 0.25 million gallons per day. Construction dewatering and
miscellaneous dewatering/low-threat discharges are among the types of discharges that may be
covered by the permit. To receive coverage under this general permit, the discharger must submit
a Notice of Intent to the RWQCB and describe the activity with sufficient detail to demonstrate
that discharge would comply with the discharge prohibitions, effluent limitations, and receiving
water limitations outlined in the order. In no case shall the discharge impair beneficial uses or
violate water quality standards or cause a possible nuisance condition. This permit would be
required in the event dewatering discharges would be made to a creek, such as might be necessary
during foundation excavations, utility trenching, or other site construction activities. If the
discharge is made to land (e.g., to a temporary infiltration/percolation basin on site) the project
proponent would need to apply for coverage under the Statewide General Waste Discharge
Requirements for Discharges to Land with a Low Threat to Water Quality (SWRCB Order No.
2003-0003-DWQ) or equivalent. The intent and procedures for coverage under this permit are
similar as described above.
California Sustainable Groundwater Act
The Sustainable Groundwater Management Act (SGMA) is a package of three bills (Assembly Bill
[AB] 1739, SB 1168, and SB 1319) that provides local agencies with a framework for managing
groundwater basins in a sustainable manner. The SGMA establishes minimum standards for
sustainable groundwater management, roles and responsibilities for local agencies that manage
groundwater resources, and priorities and timelines to achieve sustainable groundwater management
within 20 years of adoption of a Groundwater Sustainability Plan (GSP). Central to the SGMA are
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-19
the identification of critically over-drafted basins, prioritization of groundwater basins,
establishment of Groundwater Sustainability Agencies (GSAs), and preparation and implementation
of GSPs for medium-priority, high-priority, and critically over-drafted basins. GSAs must be formed
by June 30, 2017. GSPs must consider all beneficial uses and users of groundwater in the basin, as
well as include measurable objectives and interim milestones that ensure basin sustainability. A basin
may be managed by a single GSP or multiple coordinated GSPs.
At the state level, DWR has the primary role in the implementation, administration, and oversight
of the SGMA, with the SWRCB stepping in should a local agency be found to not be managing
groundwater in a sustainable manner. DWR recently approved regulations and guidelines for
implementation of the SGMA.
The project site intersects the Tracy Groundwater Subbasin (DWR Basin No. 5-22.15), which is a
medium priority basin and will eventually be managed under a GSP. The County, the Cities of
Antioch and Brentwood, Byron-Bethany Irrigation District, Diablo Water District, Discovery Bay
Community Services District, and East Contra Costa Irrigation District are the GSAs within the
Contra Costa County portion of the Tracy Groundwater Subbasin. All seven GSAs have signed a
memorandum of understanding agreeing to prepare a single GSP for the groundwater basin within
the County. The GSP must be submitted to DWR by January 31, 2022.
Groundwater Management Act
Groundwater management is outlined in the California Water Code, Division 6, Part 2.75, Chapters
1–5, Sections 10750 through 10755.4. The Groundwater Management Act was first introduced in
1992 as AB 3030 and has since been modified by SB 1938 in 2002 and AB 359 in 2011. These
significant pieces of legislation establish, among other things, specific procedures on how
Groundwater Management Plans (GWMPs) are to be developed and adopted by local agencies.
The intent of the Groundwater Management Act is to encourage local agencies to work
cooperatively to manage groundwater resources within their jurisdictions and to provide a
methodology for developing a GWMP.
• Assembly Bill 3030: AB 3030 was signed into law in 1992 and provides a systematic
procedure for a local agency to develop a GWMP.
• Senate Bill 1938: SB 1938, signed into law in 2002, modified the Groundwater
Management Act by requiring any public agency seeking state funds administered through
DWR for the construction of groundwater projects to prepare and implement a GWMP
with specified required components. The SB 1938 requirements apply not just to
management areas that overlie Bulletin 118–defined groundwater basins, but to those
agencies that have groundwater management outside of those basins.
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-20
• Assembly Bill 359: AB 359, signed into law in 2011, modified the Groundwater Management
Act by requiring public agencies to prepare and implement a GWMP with an additional
required component that is focused on identifying groundwater recharge areas. The AB 359
legislation also includes several plan adoption procedural changes, requires GWMPs to be
submitted to DWR, and requires DWR to provide public access to this information.
There are no AB 359, SB 1938, or AB 3030 GWMPs applicable to the project site.

Contra Costa County Municipal Code Section 1014 – Stormwater M anagement and
Discharge Control
The purpose of County Municipal Code Section 1014 is to eliminate, to the maximum extent
practicable, the discharge of pollutants into local watercourses and municipal storm drain systems.
Section 1014 requires that all projects creating and/or redeveloping at least 10,000 square feet of
impervious surface, or 5,000 square feet for auto service facilities, gas stations, restaurants, and
uncovered parking lots, provide treatment of stormwater runoff generated by the project. Projects
creating and/or redeveloping impervious surface in excess of 1 acre are required to not only treat
stormwater runoff, but also provide hydrograph modification management (resulting in post-
project stormwater runoff flow rates and durations effectively matching the estimated pre-project
levels). This section of the County Municipal Code, as well as the County’s Stormwater
Management and Discharge Control Ordinance (Section 1014), is intended to achieve compliance
with Provision C.3 of the County’s MS4 NPDES Permit issued by the Central Valley RWQCB, as
described in detail above.
Contra Costa County Municipal Code Chapter 82-28 – Floodplain Management Ordinance
The Floodplain Management Ordinance applies to all FEMA-designated SFHAs within the
County’s jurisdiction. The purpose of the ordinance is to promote public health and safety and
minimize public and private losses due to flood conditions. This is accomplished through
provisions designed to protect human life and property; minimize damage to public facilities and
utilities such as water and gas mains, electric, telephone, and sewer lines, and streets and bridges
located in areas of special flood hazard; minimize the need for rescue and relief efforts associated
with flooding and generally undertaken at the expense of the general public; minimize public
expenditure on flood projects; and provide information to the public regarding SFHAs. The
ordinance establishes the requirement for a floodplain permit, which must be obtained prior to
issuance of a grading permit or building permit, or commencement of development, on any
3.8 – HYDROLOGY AND WATER QUALITY

property within any area of special flood hazards, and also establishes construction standards
pertaining to structure anchoring, construction materials and methods, elevation above the base
flood height, and flood proofing.
Contra Costa County Drainage Ordinances
A drainage permit under Division 914 and/or Division 1010, Drainage, of the County Ordinance
Code would be required for installation of culverts proposed as part of the project, and within
existing drainage ditches and tributaries to Brushy Creek. Among other things, the ordinance
prohibits the impairment or impedance of the natural flow of stormwaters; direct physical impacts
to watercourses (e.g., through grading, excavation, filling, and/or development); or the
construction, alteration, or repair of a drainage structure, facility, or channel without first obtaining
a permit from the public works department. Furthermore, Division 914 establishes on-site and off-
site collect and convey requirements that must be met before development approvals are granted.
Applicants are required to substantiate that both on-site and off-site drainage facilities have
adequate capacity to convey specified design storm events, that the capacity and stability of natural
watercourses are adequately protected, and that environmentally sensitive flow velocity
attenuation techniques approved by the public works department are implemented. Detention
basins must be approved by the public works department and are required to detain the 100 -year
storm runoff.
3.8.3 Thresholds of Significance
The significance criteria used to evaluate the project’s impacts to hydrology and water quality are
based on Appendix G of the CEQA Guidelines. A significant impact related to hydrology and
water quality would occur if a project would:
1. Violate any water quality standards or waste discharge requirements or otherwise
substantially degrade surface or ground water quality.
2. Substantially decrease groundwater supplies or interfere substantially with groundwater
recharge such that the project may impede sustainable groundwater management of the basin.
3. Substantially alter the existing drainage pattern of the site or area, including through the
alteration of the course of a stream or river or through the addition of impervious surfaces,
in a manner which would:
(a) result in substantial erosion or siltation on or off site;
(b) substantially increase the rate or amount of surface runoff in a manner which would
result in flooding on- or off-site;
3.8 – HYDROLOGY AND WATER QUALITY

February 2022 3.8-24
(c) create or contribute runoff water which would exceed the capacity of existing or
planned stormwater drainage systems or provide substantial additional sources of
polluted runoff; or
(d) impede or redirect flood flows.
4. In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation.
5. Conflict with or obstruct implementation of a water quality control plan or sustainable
groundwater management plan.
3.8.4 Impacts Analysis
Impact 3.8-1. The project would not violate water quality standards or waste discharge
requirements or otherwise substantially degrade surface or ground water
quality. (Less than Significant)
Impacts to water quality through exceedance of water quality standards, non-conformance with
WDRs, or by other means can potentially result from the short-term effects of construction activity
(e.g., erosion and sedimentation due to land disturbances, uncontained material and equipment
storage areas, improper handling of hazardous materials) and the long-term effects of landscaping,
circulation improvements, utility infrastructure, and structural designs (e.g., alteration of drainage
patterns, use/handling of hazardous materials, and/or increases in impervious surfaces).
Construction Impacts
Construction period activities could generate stormwater runoff that could cause or contribute to a
violation of water quality standards or WDRs, provide substantial additional sources of polluted
runoff, or otherwise substantially degrade the water quality of receiving waters, which in most
cases consist of the underlying groundwater, but in extreme cases such as a 10-year flood or
greater, could consist of Brushy Creek and downstream waters. In areas of active construction, soil
erosion may result in discharges of sediment-laden stormwater runoff into the existing or proposed
stormwater drainage system, if not properly controlled. Without proper controls, this could
contribute to degradation of downstream water quality and impairment of the beneficial uses
identified in Section 3.8.2. Sediment can also be a carrier for other pollutants, such as heavy metals,
nutrients, pathogens, oil and grease, fuels, and other petroleum products. In addition to sediment,
other pollutants associated with the various phases of construction, such as trash, paint, solvents,
sanitary waste from portable restrooms, and concrete curing compounds, can discharge into and
impair receiving waters if released during construction.
As part of the permitting and approval of individual uses proposed by the project, project proponents
would be required to develop and implement a SWPPP in accordance with SWRCB and Central Valley
RWQCB requirements (as described in Section 3.8.2). The SWPPP must specify the location, type,
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-25
and maintenance requirements for BMPs necessary to prevent stormwater runoff from carrying
construction-related pollutants into nearby receiving waters (in this case, the southern part of the
Sacramento–San Joaquin Delta). BMPs must be implemented to address potential release of fuels, oil,
and/or lubricants from construction vehicles and equipment (e.g., drip pans, secondary containment,
washing stations); release of sediment from material stockpiles and other construction-related
excavations (e.g., sediment barriers, soil binders); and other construction-related activities with the
potential to adversely affect water quality. The number, type, location, and maintenance requirements
of BMPs to be implemented as part of the SWPPP depend on site-specific risk factors such as soil
erosivity factors, construction season/duration, and receiving water sensitivity.
SWPPPs must be developed and implemented by a Construction General Permit Qualified SWPPP
Developer/Qualified SWPPP Practitioner. The Qualified SWPPP Developer/Qualified SWPPP
Practitioner is tasked with determining the receiving water risks (including beneficial uses and
CWA Section 303d impairments), monitoring site activities that could pose risks to water quality,
and developing a comprehensive strategy to control construction-related pollutant loads in site
runoff. Minimum standard BMPs include erosion and sediment controls; site
management/housekeeping/waste management; management of non-stormwater discharges; run-
on and runoff controls; and BMP inspection, maintenance, and repair activities. A rain event action
plan must also be prepared by the Qualified SWPPP Developer/Qualified SWPPP Practitioner to
outline the procedures to prepare the construction site for rain events and minimize the potential
release of construction-related contaminants.
The following list includes examples of treatment control BMPs to employ during construction,
although these would vary based on the nature of construction activities, the characteristics of the
site, and the existing impairments applicable to receiving waters (these features would appear as
notes on final design plans):
• Silt fences installed along limits of work and/or the construction site
• Stockpile containment (e.g., visqueen, fiber rolls, gravel bags)
• Exposed soil stabilization structures (e.g., fiber matrix on slopes and construction access
stabilization mechanisms)
• Street sweeping
• Tire washes for equipment
• Runoff control devices (e.g., drainage swales, gravel bag barriers/chevrons, velocity check
dams) shall be used during construction phases conducted during the rainy season.
• Drainage system inlet protection
• Wind erosion (dust) controls
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-26
• Tracking controls
• Prevention of fluid leaks (inspections and drip pans) from vehicles
• Dewatering operations best practices
• Materials pollution management
• Proper waste management
• Regular inspections and maintenance of BMPs
The standard requirements contained in a SWPPP are sufficient to address a project’s potential to
violate water quality standards or WDRs. Implementation of SWRCB and Central Valley RWQCB
requirements (CWA NPDES Program and Porter–Cologne Water Quality Control Act WDRs) are
enforced by the County through Division 1014 (Stormwater Management and Discharge Control)
of the County Ordinance Code. In addition to stormwater runoff, construction activities can
generate fugitive dust, which, if not properly controlled, can be deposited in nearby waters. Note
that this potential impact is addressed in Section 3.2, Air Quality; actions to mitigate adverse
effects on air quality would likewise mitigate potential adverse effects on water quality from
atmospheric deposition. Therefore, the construction-related impact of the project on water quality
would be less than significant because existing permitting requirements are sufficient to meet
Basin Plan objectives and prevent adverse effects on beneficial uses.
Operational Impacts
The project would involve construction of impervious surfaces such as roofs, driveways, and
parking lots, upon which pollutants such as dust/sediment, vehicle and aircraft fluids, oil, and
grease could accumulate and come into contact with rain and stormwater runoff, which could
discharge into the airport’s stormwater drainage system. The aviation and non-aviation uses (e.g.,
retail, service, warehouse and distribution, and light manufacturing uses) proposed are typically
associated with a high coverage of impervious surfaces and can involve the storage/management
of hazardous materials. Pollutants could be generated from loading, delivery, and trash pick-up
areas and/or the use of open storage areas to store bulk materials, depending on the specific uses
ultimately developed in the aviation and non-aviation areas. If not properly controlled, the
discharge of polluted stormwater runoff could adversely affect water quality and the beneficial
uses of receiving waters.
Byron Airport is currently enrolled in the IGP (SWRCB Order No. 2014 -0057-DWQ) under
waste discharge identification number 5S07I002606. “Aircraft and aircraft -related activities”
and “transportation with vehicle maintenance” facilities are two of the many categories of
industrial activities covered by the IGP, which is designed to require project proponents to
address industry- and site-specific threats to water quality. The IGP requires permittees to
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-27
identify, describe, and assess project -specific pollutant sources; implement minimum and
advanced BMPs designed for those pollutant sources and protective of receiving wat ers; and
conduct long -term monitoring and reporting to demonstrate the objectives of the IGP are being
met and the quality of receiving waters is not being degraded. Performance standards for BMPs
specified in the IGP include use of best available technolo gy economically achievable and best
conventional pollutant control technology to reduce or prevent pollutants in stormwater
discharges and authorized non -stormwater discharges; the BMPs must be designed to meet
discharge prohibitions, effluent and receivin g water limitations, TMDLs, and water quality
objectives in the Basin Plan. BMPs could include active treatment systems (e.g., pre -settlement
tank and multiple filtration systems, as necessary) that target industry - and site-specific
pollutants prior to di scharge, as well as stormwater effluent testing during each qualifying
rainfall event.
Byron Airport is currently operating under an industrial SWPPP and submits reports to the
SWRCB on an annual basis documenting its compliance activities (ACMG 2016). The airport’s
SWPPP is a living document and is updated as needed in concert with RWQCB requirements
and/or changes to facility activities and operations (ACMG 2016). During qualifying storm events,
when discharges are made to the site’s outfall, the airport collects samples of the flow for testing
so that it can verify to the SWRCB that it is not contributing to water quality impairments or
violations of Basin Plan objectives. The annual report also serves to continually update
descriptions of industrial materials and storage/containment devices, and documents activities
undertaken by the airport to keep stormwater facilities and pollution controls working effectively.
Review of the SWRCB’s Storm Water Multiple Application and Report Tracking System indicates
that the facility has never been in violation of permit conditions since adoption of the 2014 IGP
(SWRCB 2019).
The existing uses would continue to operate under the industrial SWPPP in effect for the Byron
Airport, which would continue to be amended as required. Future aviation uses or non-aviation uses
that are covered facilities under the IGP would either be folded into the existing IGP coverage
through a SWPPP amendment or would be required to obtain coverage under a separate waste
discharge identification number, depending on arrangement between landowner and lessee. For
leases that would qualify as an industrial facility under the general permit, the project proponent
would not be authorized to construct and operate the facility without first obtaining coverage under
the IGP, which is accomplished by submitting to the Central Valley RWQCB all required permit
registration documents, including a Notice of Intent and an Industrial SWPPP. The Industrial
SWPPP would contain, at a minimum, (1) the facility name and contact information, (2) a site map,
(3) a list of industrial materials handled, (4/5) a description and assessment of pollutant sources, (6)
minimum BMPs, (7) advanced BMPs, where applicable, (8) a monitoring and implementation plan,
(9) an annual comprehensive facility compliance evaluation, and (10) the date that the SWPPP was
initially prepared and the date of each SWPPP amendment, where applicable.
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-28
Future development of airport-related uses not defined as a covered facility under the IGP would
require compliance with the east Contra Costa County MS4 Permit (Order No. R5-2010-0102), as
described in Section 3.8.2. Provision C.3 of the MS4 Permit addresses post-construction stormwater
management requirements for new development and redevelopment projects. Currently, the County
requires project proponents to install hydrodynamic devices or incorporate other BMPs to remove
pollutants, such as floating liquids and solids, trash and debris, and coarse sediment, from stormwater
runoff and to show the locations of such controls on plans submitted with the development
application (when a discretionary permit is required) and/or building permit application. In addition,
the County requires implementation of LID strategies, preventative source controls, and additional
stormwater treatment measures to minimize the discharge of pollutants in stormwater runoff and
non-stormwater discharge of certain industrial projects, as well as to prevent of an increase in runoff
flows. Additional details on these requirements are provided in Section 3.8.2.
Required compliance with the IGP and the east Contra Costa County MS4 Permit, as
applicable, would effectively avoid or substantially reduce the project’s potential to violate
water quality standards or WDRs or otherwise substantially degrade surface or groundwater
quality . Therefore, the impact of operation and maintenance of the project on water quality
would be less than significant . Impacts of the project regarding drainage and runoff alterations
are addressed under Impact 3.8 -3.
Impact 3.8-2. The project would not substantially decrease groundwater supplies or interfere
substantially with groundwater recharge such that the project may impede
sustainable groundwater management of the basin. (Less than Significant)
As discussed in Section 3.8.1, Existing Conditions, the proposed project is located in the Tracy
Groundwater Subbasin of the San Joaquin Valley Groundwater Basin (DWR Basin No. 5-022.15),
as defined by the DWR (2003). The Tracy Groundwater Subbasin is a medium priority basin and
will eventually be managed under a GSP. DWR’s priority rating is based on estimates of population
density, anticipated growth, well density, the amount of irrigated agriculture, the degree to which
water demands are met from wells (versus surface water), and the existence of documented impacts
(e.g., overdraft) (DWR 2014). More than 80% of the municipal and agricultural water demands
within the subbasin are served by surface water supplies, primarily from the California Aqueduct,
and, as discussed in Section 3.8.1, groundwater levels have been generally stable in the past several
decades (DWR 2014). The Byron-Bethany Irrigation District and the County, as part of the GSA for
the Tracy Groundwater Subbasin, will have joint responsibility for preparing and implementing a
GSP for the basin by 2022. However, there is currently no GWMP currently adopted for the part of
the basin which the proposed project overlies (e.g., AB 359, SB 1938, or AB 3030 GWMPs).
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-29
The Water Supply Assessment completed for the proposed project estimates that the construction
water demand for the proposed project is 31 acre-feet spread out over a 10-year build-out period,
equivalent to an average of 3.1 acre-feet per year (Appendix I). Operations and maintenance
activities for the proposed project would require a water demand that would ramp up to
approximately 36 acre-feet per year by the end of the 10-year build-out period (Appendix I). Due
to low yield and poor water quality, groundwater is unlikely to be utilized to meet the water
demands of the project; instead, the water demands are anticipated to be met by surface water
imports from the Byron-Bethany Irrigation District and/or the Town of Discovery Bay (Appendix
I). However, the proposed project would retain the capability to either construct a new well or
redevelop its existing well for a backup or emergency source of water.
Should groundwater be utilized to meet some or all of the proposed project’s water demands, the
impacts on aquifer depletion and/or the local lowering of the groundwater table would be minimal.
This is because there are no municipal water wells in the region surrounding the proposed project,
and the existing domestic and irrigation wells in the area surrounding the project are a sufficient
distance away to avoid experiencing pumping interference (DWR 2018a, 2018b). Average
groundwater use in the Tracy Subbasin is estimated to be between 0.03 and 0.1 acre-feet/acre
(DWR 2014). Given the Byron Airport is approximately 1,319 acres in size, the maximum water
demand of the proposed project, if it were to come entirely from the groundwater aquifer (which
is not anticipated), would represent a water use of 0.03 acre-feet/acre, which is consistent with the
lower end of the range of the average groundwater use in the Tracy Subbasin. Given this level of
groundwater pumping has not produced declining groundwater levels, it would not have
substantial adverse impacts with regard to aquifer depletion.
Furthermore, the proposed project would have minimal impacts with respect to groundwater
recharge. Although planned uses are likely to include a substantial amount of impervious surfaces,
which would locally prevent infiltration, stormflows would be diverted to the site’s stormwater
detention basin, where the accumulated flow would be available for infiltration. Under existing
conditions, as described in Section 3.5, Geology and Soils, the project site contains soils that are
not naturally conducive to recharge, since they contain significant amount of clay and therefore
have hydrologic soil group ratings of C and D (i.e., slowly to very slowly permeable). Furthermore,
compliance with the IGP and MS4 Permit (described under Impact 3.8-1) would include BMPs
and LID strategies to manage runoff and water quality, which could include swales and/or
infiltration basins which would collect runoff from impervious areas. While impervious surfaces
would result in localized decreases in infiltration, the runoff volume from impervious surfaces
would be directed to locations (e.g., water quality BMPs and/or detention basin) where it could
infiltrate into the underlying groundwater aquifer. Therefore, the project would not significantly
change the overall volume of the recharge to the Tracy Groundwater Subbasin.
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-30
For these reasons, the impacts of the proposed project on the sustainable management of
groundwater (e.g., aquifer depletion, well interference, and groundwater recharge) would be less
than significant.
Impact 3.8-3. The project would not substantially alter the existing drainage pattern of the
site or area, including through the alteration of the course of a stream or river
or through the addition of impervious surfaces, in a manner which would: (a)
result in substantial erosion or siltation on or off site; (b) substantially increase
the rate or amount of surface runoff in a manner which would result in
flooding on- or off-site; (c)create or contribute runoff water which would
exceed the capacity of existing or planned stormwater drainage systems or
provide substantial additional sources of polluted runoff; or (d) impede or
redirect flood flows. (Potentially Significant)
Drainage patterns of the site can be altered through several means, including significant grading
(i.e., alteration of topography), whereby the natural drainage areas of the site are altered, or through
addition of impervious surfaces, which can increase the rate and volume of storm runoff, thereby
increasing the magnitude and accelerating the arrival time of peak flows in downstream
waterways. The project would not substantially alter the site’s topography because the areas
planned for the aviation and non-aviation uses are located on previously graded pads or are
otherwise on land that is already relatively flat. Currently undeveloped areas planned for the
aviation and non-aviation uses have average slopes of 1.5% or less (Google Earth 2018). Minor,
localized changes in topography may occur as development of these areas proceeds; however,
these changes would not be substantial enough to alter the pre-existing watershed boundaries or
the general drainage pattern shown in Figure 3.8-2.
Prior to and at full build-out, the project would involve substantial increases in the amount of
impervious surfaces, which has the potential to substantially increase the rate and volume of storm
runoff during peak storm events without adequate measures to detain, retain, or slow the increased
flows. The distribution and extent of impervious surfaces to be constructed is not known precisely
at this time but would occur in a 70-acre area planned for non-aviation uses (46.6 acres) and the
aviation area (23.5 acres). At full build-out, the total building footprint for all new uses is
anticipated to be approximately 914,000 square feet (or 21 acres). Though some of this area may
consist of landscaping or water quality control BMPs (e.g., swales, gravel, or pervious pavement),
the majority of the building footprint is expected to consist of impervious surfaces, given the
anticipated uses (e.g., typically 80% to 90% of the building footprint). The following subsections
examine the impacts that altered flow regimes would have on erosion or siltation, on- or off-site
flooding, the capacity of existing or planned stormwater drainage systems, and the impedance or
redirection of flood flows.
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-31
Erosion and Siltation
Alteration in the flow regime (i.e., increases in the volume and rate of stormwater runoff) can
increase erosion and siltation beyond naturally occurring levels within receiving waters. The
primary receiving waters for the project site consist of Brushy Creek (shown in Figure 3.8-1) and
the existing detention basin (shown in Figure 3.8-2). The majority of the project site drains to the
detention basin, which means these areas would not have an impact on sedimentation and siltation
within Brushy Creek, except under an extreme storm scenario when the detention basin reaches its
holding capacity. At that point, the basin as currently constructed would release excess storm flow
into a ditch that flows north under Holey Road and then northeast to the lower-most reach of
Brushy Creek near Byron Highway, about 0.5 miles upstream of its confluence with Indian Slough.
Erosion and siltation are water quality concerns that are addressed comprehensively under Impact
3.8-1. As discussed therein, compliance with the Construction General Permit (SWRCB Order
2009-0009-DWQ, as amended), the IGP, and the East Contra Costa County MS4 Permit would
ensure that erosion and siltation are minimized through centralized and/or distributed
implementation of both temporary (construction) and permanent (operation and maintenance)
water quality BMPs. Compliance with state and federal water quality regulations and permits are
enforced through Division 1014 (Stormwater Management and Discharge Control) of the County
Ordinance Code. For the same reasons discussed under Impact 3.8-1, the impact of the project on
water quality (including erosion and siltation) would be less than significant.
Under the Construction General Permit, MS4 Permit, and IGP, water quality BMPs are typically
focused on the capture and treatment of the more typical (frequent) peak storm events. The exact
performance standard varies between regulations and permit programs, but typically require water
quality BMPs to be designed to the amount of runoff produced in a storm with a 2-year recurrence
interval (e.g., 85th percentile 24-hour storm runoff event). Project-related increase in runoff
produced by more extreme events must be addressed with conveyance, detention, and flood control
improvements necessary to avoid flood-related damage to structures and the environment,
addressed below under On-Site and Off-Site Flooding.
On-Site or Off-Site Flooding
The project, due to the aforementioned increases in impervious surfaces, could result in increases
in runoff to the on-site detention basin and to Brushy Creek, which is a natural waterway. If not
properly controlled, such increases in runoff could exacerbate on- or off-site flooding that already
occurs as part of the existing conditions. This impact would be potentially significant.
As discussed in Section 3.8.2, a drainage permit would be required to comply with Division 914
of the County Ordinance Code. Among other things, the ordinance prohibits the impairment or
impedance of the natural flow of stormwaters; direct physical impacts to watercourses (e.g.,
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-32
through grading, excavation, filling, and/or development); or the construction, alteration or repair
of a drainage structure, facility, or channel without first obtaining a permit from the public works
department. Division 914 establishes on-site and off-site collect and convey requirements that must
be met before development approvals are granted. Applicants are required to substantiate that both
on-site and off-site drainage facilities have adequate capacity to convey specified design storm
events, that the capacity and stability of natural watercourses are adequately protected, and that
environmentally sensitive flow velocity attenuation techniques approved by the public works
department are implemented.
Brushy Creek is a major drainage facility and natural watercourse with a 16-square-mile
watershed, whereas the on-site detention basin is estimated to serve a watershed area of under 1
square mile. The majority of the planned development is anticipated to drain to the existing
detention basin, based on the drainage pattern shown in Figure 3.8-2 and described in Section
3.8.1. Because the northern edge of the area planned for airport-related uses is close to Brushy
Creek, some developed uses may direct drainage to Brushy Creek. Because a hydrology and
drainage study has not been completed, it is assumed that the impacts associated with increased
runoff during storm events in excess of the 2-year flow are potentially significant. Mitigation
Measure (MM) HYD-1 would require the preparation of a drainage and hydrology study to
evaluate the difference between pre- and post-project storm flows, and establish drainage designs
necessary to mitigate the increase and adequately collect and convey flood flows.
Existing or Planned Stormwater Drainage Systems
It is possible the existing detention basin that serves the airport would not be sufficient to meet the
volume and/or water quality requirements of the full build-out scenario for future development.
As discussed under Impact 3.8-1, it is expected that LID controls and parcel/project-specific flow
control BMPs required under the IGP or MS4 Permit would result in no net increase in runoff from
individual developments for more frequent peak flow events. Impact 3.8-1 also describes how
parcel-specific stormwater systems would be planned, designed, constructed, and maintained
adequately in accordance with applicable water quality regulations. However, sufficient detail is
not available to know with certainty whether or not the capacity of the existing stormwater system
would be exceeded under a full build-out scenario. Sufficient land is available (designated for
airport-related or low intensity uses on the Byron Airport Master Plan) to accommodate
modifications or additions to the site’s existing stormwater system or detention basin.
Implementation of MM-HYD-1 would ensure that the capacity of the detention basin is adequate
to accommodate the project.
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-33
Impedance or Redirection of Flood Flows
According to FEMA, there is an SFHA (100-year flood hazard area, or a 1% annual chance flood
hazard) associated with Brushy Creek (FEMA 2017). The flood zone widens significantly along
Brushy Creek in an area located west of Runway 12-30 and west of Falcon Way, and spreads over
low-lying areas between the two runways and south of Runway 5-23 (Figure 3.8-3, FEMA Flood
Hazard Zones). The majority of the flood zone shown is largely confined to areas of the project site
that would be designated as habitat management or low intensity use, which would not have
development to impede or redirect flood flows. However, the flood zone intersects the northern end
of the proposed airport-related uses south of Armstrong Road and north-northeast of Runway 12-30
(FEMA 2017). In this area, the 100-year flood hazard area overlaps approximately 11.5 acres of area
zoned for airport-related uses to a width of up to 800 feet. Also shown in Figure 3.8-3 is a regulatory
floodway along Brushy Creek, which ranges between 80 and 255 feet in width, and occupies
approximately 2.2 acres out of the 11.5 acres area in which planned development and the flood
hazard area overlap. Without proper design, proposed uses could impede or redirect flood flows.
Airport-related uses proposed on either side of Brushy Creek, especially those within the
regulatory floodway, could constrict the cross-sectional area of the creek and lead to flooding
concerns. Creek and habitat conservation buffers would prevent planned development from
encroaching of the creek corridor itself and would likewise limit encroachment onto the regulatory
floodway. However, considering up to 11.5 acres of the area zoned for airport-related uses is within
the FEMA SFHA, the impact of the project on the impedance or redirection of flood flows is
potentially significant. MM-HYD-2 would require compliance with existing floodplain
management regulations, studies to determine and demonstrate the capacity of the creek corridor
would be maintained, coordination with FEMA if the depth or boundaries of the floodplain would
be changed as a result, and review and approval by the County Public Works Department.
Impact 3.8-4. The project would not risk release of pollutants due to project inundation in
flood hazard, tsunami, or seiche zones. (Less than Significant)
There are three large bodies of water in the project vicinity: Clifton Court Forebay less than 2
miles east of the site, Bethany Reservoir approximately 3 miles to the south, and Los Vaqueros
Reservoir 5 miles to the west. The project site is outside the mapped inundation area for Clifton
Court Forebay, Bethany Reservoir, and Los Vaqueros Reservoir. As these water bodies are 2 to 5
miles from the project site, the project site is not subject to risk from a seiche. The project is not at
risk of tsunami inundation due to its distance away from any coastline. This impact would be less
than significant.
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-34
Impact 3.8-5. The project would not conflict with or obstruct implementation of a water quality
control plan or sustainable groundwater management plan. (Less than Significant)
As discussed under Impact 3.8-1, the project would comply with applicable regulations and permits
designed to comply with the Water Quality Control Plan for the Sacramento River Basin and San
Joaquin River Basin. As discussed under Impact 3.8-2, there is no sustainable GWMP currently
adopted for the Tracy Groundwater Subbasin of the San Joaquin Valley Groundwater Basin (DWR
Basin No. 5-022.15). It is expected that a GSP will be adopted by 2022; however, for the reasons
discussed in Impact 3.8-2, the impacts of the project on the sustainable management of groundwater
(e.g., aquifer depletion, well interference, and groundwater recharge) would be less than significant.
3.8.5 Mitigation Measures
Implementation of the following mitigation measures would reduce Impact 3.8-3 to a less-than-
significant level.
MM-HYD-1 Hydrology and Drainage Study. Prior to approval of individual development
plans, a Hydrology and Drainage Study shall be prepared for the project to refine
the size and hydrologic characteristics of drainage areas that intersect the project
site, to estimate pre- and post-project flow rates and volumes under 10- 25-, 50-
and 100-year storm events, and to provide recommendations for needed
improvements. The Hydrology and Drainage Study shall quantify the capacity of
the existing detention basin; determine whether or not it will be sufficient to serve
future land uses; and establish the hydrology performance criteria and design
standards applicable to potential future tenants, based on the destination of runoff
(i.e., detention basin or Brushy Creek) and the degree of impervious surface
coverage. The study shall be consistent with the hydrology performance criteria and
design standards contained within the Contra Costa County Drainage Ordinance
(Division 914), which include but are not limited to:
• Drainage facilities shall be designed to convey a minimum (with sufficient
freeboard) of the runoff produced by a) a 10-year storm event for facilities
draining an area of less than 1 square mile, b) a 25-year storm event for
facilities draining an area of between 1 and 4 square miles, and c) a 50-year
storm event (and 100-year event without freeboard) for facilities draining
an area of more than 4 square mile.
• Finished floors shall be elevated above the base flood elevation of the one-
hundred-year frequency storm runoff, as determined using the maximum
potential development of the drainage basin or watershed shall.
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-35
• Storm flows shall be collected and conveyed in a manner that avoids
damage to any improvement, building site or dwelling which may be
constructed as part of the project.
• Detention basins shall be sized to contain without freeboard a one-hundred-
year average recurrence interval runoff, unless it can be shown that a one-
hundred-year average recurrence interval runoff can be safely passed
through the detention basin without damage to the detention basin or any
other property.
• Drainage capacity shall be provided that accounts for the full build-out of
uses anticipated with the drainage area.
The study shall be submitted to the Contra Costa County Public Works Department
(Flood Control District) for review and approval prior to finalizing individual
development plans. In addition, the Hydrology and Drainage Study shall be
reviewed by Airports Division staff to ensure any drainage basins proposed are
consistent with Federal Aviation Administration aviation obstruction standards for
avian attractants (e.g., requirement to drain ponded water within 48 hours of a major
storm event).
MM-HYD-2 Drainage Protection and Flood Control. For all areas of the project within the
Federal Emergency Management Agency (FEMA) 100-year floodplain (Special
Flood Hazard Area [SFHA]), Contra Costa County shall ensure that development
proposals are consistent with the requirements of the Contra Costa County
Floodplain Management Ordinance (Municipal Code Chapter 82-28), Contra Costa
County Flood Control Ordinance, and FEMA National Flood Insurance Program.
Development proposals in this area shall be submitted to the Contra Costa County
Public Works Department for review and approval, and all requirements imposed
by the department shall be satisfied. Such requirements may include floodproofing
measures (such as elevating structures above the base flood elevation and providing
the required freeboard). In the event development proposals involve encroachment
onto or undergrounding of Brushy Creek, a Clean Water Act Section 404 Permit
from the U.S. Army Corps of Engineers shall be obtained, per MM-BIO-6, and the
Contra Costa County Public Works Department shall be provided with drainage
studies and engineering reports sufficient to demonstrate that flood flows on Brushy
Creek would not be impeded or redirected. For all development planned within the
FEMA 100-year floodplain, subject to approval of the Contra Costa County Public
Works Department, the developer would be required to file a Conditional Letter of
Map Revision to process the change and shall obtain a FEMA modification of the
SFHA as shown on the Flood Insurance Rate Map.
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-36
3.8.6 Level of Significance After Mitigation
With implementation of MM-HYD-1 and MM-HYD-2, the impacts of the project on hydrology
and water quality (Impact 3.8-3) would be less than significant.
3.8.7 Cumulative Impacts
The setting for the cumulative analysis for surface water is the 243-square-mile Old River
Watershed (HUC 1804000306), shown in Figure 3.8-1. The setting for the cumulative analysis for
groundwater is the Tracy Groundwater Subbasin (DWR Basin No. 5-022.15). The cumulative
effects of past and current projects in the cumulative scenario have resulted in water quality
problems in the region’s major waterways, which are described in Section 3.8.1 and are reflected
in the plans and policies contained in the Basin Plan. Cumulatively considerable water quality
issues are identified as water quality limited segments (or impaired water bodies) under CWA
Section 303(d). As described in Table 3.8-3, impairments related to low dissolved oxygen,
chlorpyrifos, TDS, and electrical conductivity are identified for Old River and its tributaries.
Though CWA Section 303(d) does not apply to groundwater, the Basin Plan addresses
groundwater through the establishment of water quality objectives for bacteria, chemical
constituents, pesticides, radioactivity, salinity, tastes and odors, and toxicity. The groundwater
basin is known to have elevated levels of TDS, chloride, nitrate, and boron. In many ways, the
analysis of each impact in Section 3.8.4 is also a cumulative analysis, because the thresholds of
significance considers even minor, localized, and temporary contributions of pollutants potentially
significant, due to the cumulative effects of multiple projects within the watershed. The analysis
of groundwater (Impact 3.8-2) considers the cumulative context of the whole basin.
The projects in the cumulative scenario that may result in contributions to water quality issues
include all development projects that either result in land disturbance, creation of impervious
surfaces, and/or release or discharge of pollutants to regional waters. This includes development
identified in the County General Plan. Note that most of the land within the watershed is designated
for agriculture, public use, open space, and delta recreation (see Figure 3.9-2, Existing General
Plan, in Section 3.9, Land Use and Planning).
The NPDES permits relevant to the proposed project (e.g., Construction General Permit, MS4
Permit, and IGP) are aimed at maintaining the beneficial uses of the water bodies in the Basin Plan
and meeting water quality objectives associated with specific pollutants of concern. Because
adverse water quality and major hydrologic alterations are linked to the large-scale, cumulative
effects of development projects and to commercial and/or agricultural land uses, the provisions
within the NPDES permits, by their nature, seek to address cumulative conditions. The project,
along with all other projects over 1 acre in size, would be required to obtain coverage under the
NPDES Construction General Permit, which requires project proponents to identify and implement
3.8 – HYDROLOGY AND WATER QUALITY
Byron Airport Development Program EIR 9269
February 2022 3.8-37
stormwater BMPs that effectively control erosion and sedimentation and other construction-related
pollutants. For cumulative projects under the jurisdiction of the surrounding County and
municipalities, stormwater control ordinances and grading permit approval processes also require
smaller projects (less than 1 acre) to implement a standard/minimum set of water quality BMPs.
Furthermore, all development and redevelopment projects that create or replace impervious
surfaces must comply with the regional MS4 Permit and ensure that they meet applicable water
quality standards and performance criteria through source control measures, low -impact
development BMPs, and other means.
Therefore, without compliance with existing regulations, and where required, implementation of
mitigation measures, regional impacts on water quality from all projects in the cumulative scenario
are potentially significant. With the project’s compliance with the Construction General Permit ,
MS4 Permit, and IGP, and implementation of MM-HYD-1 and MM-HYD-2, the project’s
contributions to cumulatively significant water quality impacts are reduced to less than significant
with mitigation.

3.9 LAND USE AND PLANNING
This section describes the existing land use and planning setting of the Byron Airport Development
Program (project) site, including applicable federal, state, and regional regulations. This section
considers the proposed amendments to the General Plan and zoning, the proposed update to the
Airport Land Use Compatibility Plan (ALUCP) for Byron Airport, and the potential development
that would result from these changes.
3.9.1 Existing Conditions
3.9.1.1 Regional
Byron Airport is located in southeastern Contra Costa County (County) (see Figure 2-1, Project
Location, of Chapter 2, Project Description, of this Environmental Impact Report [EIR]). Uses
around the airport primarily include agriculture (cattle grazing, vineyards, tree crops, and row
crops); additionally, rural residential uses are located to the east and west of the project site. This
small community is surrounded by agricultural lands and contains concentrated areas of single-
family residential development, commercial and light industrial development centralized along
Byron Highway, schools, churches, and wineries. Development is primarily located along Camino
Diablo, Byron Highway, and Holway Drive. There are several industrial uses on Byron Hot
Springs Road, including cement ready-mix and a recycling yard, between central Byron and the
airport. Byron Hot Springs, a now abandoned resort and former World War II prisoner of war
camp, is located north of the airport to the west of Byron Hot Springs Road.
Byron Highway is the primary regional access, located to the north and east of the project site. Byron
Highway provides access to the community of Byron, and further north, Highway 4 and the City of
Brentwood. To the south, Byron Highway provides access to the community of Mountain House, an
unincorporated planned community in San Joaquin County, and Interstate 580.
The Byron-Bethany Irrigation Canal crosses the eastern portion of the project site. The Clifton
Court Forebay is located less than 2 miles east of the site, Bethany Reservoir is approximately 3
miles to the south, and the Los Vaqueros Reservoir is 5 miles to the west. The area has numerous
wind energy turbines located in the rolling hills of the Diablo Range west of the project site—
some within 1 mile of the airport property. Byron Highway is located north and west of the project
site. Other significant development in the immediate vicinity includes several high-voltage
transmission lines within 3 miles east, west, and south, as well as a railroad line running parallel
to Byron Highway.
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-2
3.9.1.2 Project Site
The project site consists of the airport property south of Armstrong Road, which is approximately 1,307
acres, and the 11.7-acre parcel located between the airport property and the Bethany Irrigation District
Canal, for a total of 1,319 acres (see Figure 2-2, Project Site, of Chapter 2 of this EIR). The airport owns
an additional 120 acres north of Armstrong Road that is not considered part of the project site.
The airport has two runways. The primary runway, Runway 12-30 (northwest–southeast), is 4,500
feet long and 100 feet wide. The crosswind runway, Runway 5-23, is 3,000 feet long and 75 feet
wide. Both runways have 20-foot unpaved shoulders. General aviation facilities are generally
concentrated in the “V” formed by the two runways, with approximately 10 acres of aircraft storage
area, 4 acres of apron, 125,000 square feet of hangars, and 2,400 square feet of office space. The
majority of these facilities were constructed when the airport was built in the early 1990s.
Infrastructure is limited, with a detention basin located east of the crosswind runway, in the corner
formed by Holey Road and Byron Hot Springs Road. The water system consists of a domestic well
with a 4,000-gallon holding tank and a booster pump with a chlorinator. The sewer system consists
of a 3,000-gallon underground septic tank and lift station pumping to a leach field located
southwest of the main aircraft ramp.
Approximately 814 acres of the property are reserved for habitat management, consisting of open
grassland with scattered vernal pools and season wetlands and alkali grasslands.
3.9.2 Relevant Plans, Policies, and Ordinances
Federal
Federal Aviation Administration
The primary role of the Federal Aviation Administration (FAA) is to promote aviation safety and
control the use of airspace. The FAA enforces safety standards and investigates and corrects
violations as appropriate. Federal regulations applicable to compatible land use include Federal
Aviation Regulation Part 77: Safe, Efficient Use, and Preservation of the Navigable Airspace, and
Code of Federal Regulations, Title 14, Part 150, Airport Noise Compatibility Planning.
Land use at airports is guided by an FAA‐approved Airport Layout Plan (ALP), a technical set of
drawings that is a graphical representation of the long‐term development plan for the airport. Per
FAA Advisory Circular 150/5070‐6B, Airport Master Plans, an update of the ALP drawing set
should be an element of an airport master plan. Per FAA Advisory Circular 150/5070‐6B, FAA
only approves the following elements:
• Forecasts of demand
• ALPs
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-3
The Byron Airport ALP was recently updated in 2016. The approved forecasts were not changed,
and the forecasts in the 2005 Airport Master Plan remain in effect.
Code of Federal Regulations, Title 14, Part 77 (Part 77), establishes standards and notification
requirements for objects affecting navigable airspace. Part 77 regulations allow the FAA to
identify potential aeronautical hazards to prevent or minimize adverse impacts to the safe and
efficient use of navigable airspace. As a part of this process, FAA reviews buildings (aeronautical
and non‐aeronautical) on a case-by‐case basis through its Obstruction Evaluation/Airport Airspace
Analysis program review (i.e., Form 7460). If approved, the subject building receives Form 7460
clearance, which indicates that the building conforms to maximum permissible height standards
and would not create a hazard to aircraft.
State
California State Aeronautics Act
The purpose of the California State Aeronautics Act pursuant to Public Utilities Code (PUC),
Section 21001 et seq., “is to protect the public interest in aeronautics and aeronautical progress.”
The State Aeronautics Act provides for the creation of an Airport Land Use Commission (ALUC)
for every county that contains a public use airport. The purpose of an ALUC, per the State
Aeronautics Act, is to conduct airport land use compatibility planning. ALUCs protect public
health, safety, and welfare by ensuring the orderly expansion of airports and the adoption of land
use measures that minimize the public's exposure to excessive noise and safety hazards within
areas around public airports to the extent that these areas are not already devoted to incompatible
uses (PUC Sections 21670–21679.5). The primary mechanism used to accomplish airport land use
compatibility planning is the adoption of an ALUCP (PUC Sections 21674[c] and 21675).
The California Department of Transportation is involved in state aviation system planning and
research through its Division of Aeronautics and its Office of Research and New Technology.
California Department of Transportation prepares and regularly updates the California Aviation
System Plan, the vehicle by which California Department of Transportation conducts continuous
aviation system planning and guides aviation infrastructure investment priorities. The Division of
Aeronautics also prepares the state’s official guidance for preparing and implementing an ALUCP,
known as the California Airport Land Use Planning Handbook (Handbook). The Handbook was first
published in 1993 and updated in 2002. The latest edition of the Handbook was adopted in 2011.
Delta Plan
The Delta Reform Act of 2009 created the Delta Stewardship Council and required that the Council
adopt a legally enforceable Delta Plan to further the achievement of the state’s coequal goals for
the Delta - a more reliable statewide water supply and a healthy and protected ecosystem, both
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-4
achieved in a manner that protects and enhances the unique characteristics of the Delta as an
evolving place.
The Delta Plan include Policy DP P1 (Title 23 CCR Section 5010):
(a) New residential, commercial, and industrial development must be limited to the following
areas, as shown in Appendix 6 and Appendix 7:
(1) Areas that city or county general plans, as of May 16, 2013, designate for residential,
commercial, and industrial development in cities or their spheres of influence;
(2) Areas within Contra Costa County's 2006 voter-approved urban limit line, except no
new residential, commercial, and industrial development may occur on Bethel Island
unless it is consistent with the Contra Costa County general plan effective as of May
16, 2013;
(3) Areas within the Mountain House General Plan Community Boundary in San
Joaquin County; or
(4) The unincorporated Delta towns of Clarksburg, Courtland, Hood, Locke, Ryde, and
Walnut Grove.
(b) Notwithstanding subsection (a), new residential, commercial, and industrial development is
permitted outside the areas described in subsection (a) if it is consistent with the land uses
designated in county general plans as of May 16, 2013, and is otherwise consistent with this
Chapter.
(c) For purposes of Water Code section 85057.5(a)(3) and section 5001(j)(1)(E) of this Chapter,
this policy covers proposed actions that involve new residential, commercial, and industrial
development that is not located within the areas described in subsection (a). In addition, this
policy covers any such action on Bethel Island that is inconsistent with the Contra Costa
County general plan effective as of May 16, 2013. This policy does not cover commercial
recreational visitor-serving uses or facilities for processing of local crops or that provide
essential services to local farms, which are otherwise consistent with this Chapter.
(d) This policy is not intended in any way to alter the concurrent authority of the Delta Protection
Commission to separately regulate development in the Delta's Primary Zone.
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-5
Local
Airport Land Use Compatibility Plan
The ALUC with jurisdiction over the airport is the Contra Costa ALUC. The current ALUCP was
adopted in 2000 (Contra Costa County 2000). The ALUCP includes countywide policies, policies
specific to Buchanan Field and Byron Airport, and supporting information. Each airport has an
Airport Influence Area (AIA), which is the area within which airport compatibility should be
considered for land use decisions. The ALUCP considers four compatibility factors: noise, safety,
airspace protection, and overflight. Land use plans, including codes, specific plans, and zoning
ordinances, should be consistent with the ALUCP. Where the relevant land use plan has not been
found consistent with the ALUCP, or a change is proposed to that land use plan, the ALUC will
consider if the plan or land use action is consistent with the ALUCP. Note that the local land u se
agency may override the ALUC’s decision, but in so doing removes any responsibility from the
airport operator for land use conflicts.
The Byron ALUCP uses “composite zones,” which integrate noise and safety criteria when
determining the compatibility of a land use in any given area within the AIA. The 2000 ALUCP
was developed under the 1993 version of the Handbook. The current Byron Airport AIA and
compatibility zones are shown in Figure 3.9-1.
Contra Costa County General Plan
The current General Plan is the 2005–2020 General Plan, adopted in 2005. The General Plan Land
Use Map identifies the project area as a combination of Public Service and Open Space (indicating
the habitat management lands). The acquisition parcel is classified as Agriculture. See Figure 3.9-
2 for the existing General Plan land use designations for the project site.
The General Plan Transportation and Circulation Element includes numerous policies that apply
to airports and compatible development (Contra Costa County 2005).
Airports and Heliports Goals
Goal 5-Q To encourage the development and operation of two general purpose public airports
in the county.
Goal 5-R To allow heliports, restricted to appropriate locations, which would add to the
economic well-being and safety of the county.

Overall Airports Policies
Policy 5-58 Protect the Byron Airport environs from urban encroachment
through a combination of land acquisition, easement acquisitions
and land use regulations.
Policy 5-60 Work with the FAA and helicopter operators to minimize conflicts
with residential areas and sensitive land uses, such as schools,
hospitals, residences, and other sensitive noise receptors.
Special Policies that Apply to the East County Airport [Byron]
Policy 5-64 The County shall acquire fee title and/or conservation (development
rights) easements to an appropriate amount of buffer land around the
planned East County Airport.
Policy 5-65 The buffer land or conservation easements acquired around the
airport shall ensure that incompatible uses will not be allowed to
locate within the safety zone.
Policy 5-66 Establishment of commercial, industrial, or residential development
around the planned airport shall not be allowed.
Policy 5-67 Water and sewer services to the airport will be limited to serve only the
airport property; utilities will not serve growth on the adjacent properties.
Policy 5-68 No residential development or sensitive receptors, e.g. hospitals,
schools, etc., shall be allowed within the projected 60 CNEL noise
contours for the new airport.
Special Policies Regarding the Airport Land Use Commission
Policy 5-69 Structural heights shall be designated by the Federal Aviation
Regulations (FAR) Part 77 surfaces associated with the various
runway designations shown on the latest Airport Layout Plan.
Policy 5-70 The Structural Height Limits defines maximum structural height.
Height limits will be placed on new buildings, appurtenances to
buildings, all other structures and lands caping in accordance with
the Airport Layout Plan except in special instances when for
reasons of safety the Commission may impose a more restrictive
structural height.
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-7
An applicant for any structure within the Airport Land Use
Commission Planning Area proposed to penetrate any height limit
surface shall submit an aeronautical analysis which specifies the
proposed project's effect on airport instrument procedures for all
runways, the effect on airport utility, and the effect on overall
aviation safety. If, after reviewing the aeronautical study and other
related information, it is determined that the proposed project would
not have an adverse effect on safety and airport utility then, the
project may be approved for heights other than those indicated by
the FAR, Part 77, Structural Height Limits.
Policy 5-71 All major land use actions within the Buchanan Field and Byron
Airport Influence Areas as shown upon Figure 5-5 shall be referred
to the Contra Costa County Airport Land Use Commission for
comment. The definition of what constitutes a major land use action
is found on pages 2-6 through 2-8 of the Contra Costa County
Airport Land Use Compatibility Plan adopted in December of 2000.
If it is unclear whether or not an action falls within this listing, the
County should err on the side of caution and refer the matter to the
ALUC staff.
Policy 5-72 New construction or building exterior alterations located in areas of
terrain penetration as defined by the ALUC Airspace Protection
Surfaces will be reviewed on a case-by-case basis with
consideration given to topography, flight patterns, existing
vegetation and other factors which might affect airspace and safety.
The County will rely on ALUC land use compatibility guidance and
programs for considering airspace safety analysis issues and height
limitations of structures.
Policy 5-73 Temporary structures, such as construction cranes or antennae,
which would penetrate any adopted height limit surface, may be
allowed after a case-by-case review, provided that obstruction
lighting and marking is installed, and a two week notice of
temporary structure emplacement is provided by the proponent to
the County Manager of Airports. Temporary structure emplacement
shall be subject to reasonable time limit.
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-8
Policy 5-74 The County may require an exterior building materials reflectivity
analysis upon review of the proposed types of building materials,
building height, and building location and use on site. Such analyses
should be required for development of any structures on or adjacent to
public airports which would be over three stories in height and utilize
reflective surfaces. Reflectivity studies shall address the potential for
pilot and airport operation interference, proposed mitigation to any
identified potential interference resulting from reflected sunlight, and
any other subject areas related to reflectivity which the County may
deem appropriate. The County may include some or all of the proposed
mitigation in its project approval process.
Policy 5-75 Within each safety zone designated by the ALUC, the following are
incompatible uses (The ALUC Airport Influence Area Maps for
Buchanan Field Byron Airports are shown on Figure 5-5.):
1. Any light source which would direct a steady light or flashing light of red,
white, green, or amber color associated with airport operations toward an
aircraft engaged in an initial straight climb following takeoff or toward an
aircraft engaged in a straight final approach toward a landing at an airport,
other than an FAA approved facility.
2. Any construction which would cause sunlight to be reflected toward an aircraft
engaged in an initial straight climb following takeoff or toward an aircraft
engaged in a straight final approach toward a landing at the airport.
3. Any use which would generate smoke, attract large concentrations of birds, or
may otherwise adversely affect safe air navigation within a safety zone.
4. Any use which would generate electrical interference that would be
detrimental to the operation of aircraft and/or aircraft instrumentation.
5. Any use which would utilize or cause to be stored highly toxic, inflammable
or otherwise hazardous materials which, in the event of an aircraft accident,
could be released into the surrounding environment to threaten human life
or property.
6. Within the safety zone clear area, any use which involves the erection of a
permanent above ground structure other than FAA approved facilities.
7. Within the safety zones, excluding the clear areas, any use which on a
regular basis would result in a density (excluding streets) in excess of 30
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-9
persons per acre or one person/500 square feet of gross building flood area,
whichever is less.
8. Any of the following uses: new single and multiple family residences,
shopping centers, restaurants, schools, hospitals, arenas, and other places of
public assembly.
Policy 5-77 Within the ALUC Compatibility Zone B-1, no new lot splits shall
be allowed and buildings on existing lots of record shall be located
as far as practical from the extended runway centerline and shall be
limited to two stories in height.
The following are suggested uses within the ALUC Compatibility
Zones for the East Contra Costa Airport:
1. agriculture;
2. open space;
3. low intensity park and recreation uses;
4. low occupant density public uses; and
5. parking of automobiles.
Implementation Measures
Measure 5-bk Create a new zoning district for County-operated airports similar to the Planned
Unit (P-1) District zone which provides for public review of on-site projects, and
rezone both airports to that district.
Measure 5-bn Create a new zoning district to regulate private land use on the two public airports.
Zoning
The airport property south of Armstrong Road is zoned P-1 (Planned Unit District). The acquisition
parcel is zoned A-3 (Heavy Agriculture). The remainder of the airport property north of Armstrong
Road is zoned A-3. Figure 3.9-3 shows the existing zoning districts on and near the project site.
The Planned Unit District designation is intended to allow diversification in the relationship of
various uses, buildings, structures, lot sizes and open space while ensuring substantial compliance
with the General Plan and the intent of the Municipal Code in requiring adequate standards
necessary to satisfy the requirements of public health, safety, and general welfare. Currently, the
Byron Airport P-1 zoning only allows aviation-related uses, agriculture, and open space.
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-10
Chapter 86-4 of the County Zoning Ordinance, Airport Zoning, addresses land use compatibility
for airports. However, this chapter refers only to Buchanan Field by name.
3.9.3 Thresholds of Significance
The significance criteria used to evaluate the project impacts to land use and planning are based
on Appendix G of the CEQA Guidelines. According to Appendix G of the CEQA Guidelines, a
significant impact related to land use and planning would occur if the project would:
1. Physically divide an established community.
2. Cause a significant environmental impact due to a conflict with any land use plan, policy,
or regulation adopted for the purpose of avoiding or mitigating an environmental effect.
3. Conflict with any applicable habitat conservation plan or natural community conservation plan.
The project site is within the jurisdiction of the East Contra Costa Habitat Conservation Plan/Natural
Community Conservation Plan. This is discussed in Section 3.3, Biological Resources.
3.9.4 Impacts Analysis
Impact 3.9-1. The project would not physically divide an established community. (No Impact)
The nearest community is Byron, located 2.5 miles north of the project site. There are some rural
residences located near the airport. These scattered residences do not form a concentration that
could be recognized as a distinct community. The project would be contained to airport property
and the acquisition parcel adjacent to the airport property. Therefore, the project would not
physically divide an established community. There would be no impact.
Impact 3.9-2. The project would not cause a significant environmental impact due to a
conflict with any land use plan, policy, or regulation adopted for the purpose
of avoiding or mitigating an environmental effect. (Less than Significant)
Implementation of the proposed project, specifically the airport-related development, would
require amendments to the Byron ALUCP, the County General Plan, and the zoning for the airport.
ALUCP Update
As discussed above, the current ALUCP for the airport limits not only off-airport development,
but on-airport development. The 2000 ALUCP is based on older guidance (the 1993 Handbook)
and is also based on a previous Byron Airport Master Plan. As such, the ALUCP is no longer
consistent with either current compatibility guidance from the State of California or the objectives
of the airport. The proposed ALUCP update would bring the Byron Airport compatibility policies
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-11
into conformance with these plans without allowing incompatible land uses that could affect either
surrounding residents or the future operations of the airport.
In order to develop economically beneficial uses on the airport, development intensities would be
increased to a level more consistent with current Handbook guidance (Table 3.9-1). In addition,
by de-coupling the noise and safety criteria, a greater range of industrial and commercial uses
could be allowed at the airport. This approach would also create consistency with Buchanan Field,
which does not use composite compatibility zones. However, the noise contours used to establish
potential exposure to aircraft noise would not be revised. Airspace protection would not change,
as the imaginary surfaces used to analyze navigation hazards would remain the same. In addition,
the AIA would not change, although a larger notification area would be implemented (the area
within which potential homebuyers must be notified of the presence of the airport and the potential
for aircraft noise). As discussed below, the General Plan policies and zoning would only affect
airport property, and no new land uses would be allowed near the airport that are not currently
allowed. The airport environs would remain largely agricultural.

Delta Plan
The Delta Plan includes policies that are considered essential to achieving the coequal goals, and
the project is consistent with policy DP P1. Delta Plan Policy DP P1(a)(2) states, “New residential,
commercial, and industrial development must be limited to the following areas, as shown in
Appendix 6 and Appendix 7…Areas within Contra Costa County’s 2006 voter-approved urban
limit line, except no new residential, commercial, and industrial development may occur on Bethel
Island unless it is consistent with the Contra Costa County General Plan effective as of May 16,
2013.” Stated simply, projects located within Contra Costa County’s 2006 voter-approved Urban
Limit Line are not considered a covered action, as urban development is allowed within the County
ULL. Since the development that would occur as a result of the proposed project is wholly
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-12
contained within the County ULL, the proposed project is consistent with policy DP P1, which
would then result in the project supporting the achievement of the coequal goals. As it would
support the achievement of the coequal goals, the proposed project would not have a significant
impact on achievement of one or both of the coequal goals, and, therefore, the proposed project is
not a covered action under the Delta Plan.
General Plan Update
The proposed project would help implement Goal 5-Q, to encourage the development and
operation of two general purpose public airports in the county, by providing for the economic
development and financial self-sufficiency of Byron Airport.
The General Plan policies regarding the airport would be amended to clarify that compatible non-
aviation uses would be allowed on airport property. General Plan Policy 5-66 would be amended
to specify that commercial or industrial development would be allowed on-airport if it is consistent
with the ALUCP and the Byron Airport Master Plan.
The incompatible uses listed in policy 5-75 would not change, to ensure the protection of airport
operations. Policy 5-77 would be updated to reflect the new compatibility zone designations (Zone
B-1 would become Safety Zone 2) and the additional on-airport uses that may be found compatible
under the updated ALUCP. Policies protective of the future operation of the airport, and the health,
safety, and welfare of the surrounding residents would not be changed.
Zoning Amendment
The P-1 district for Byron Airport would be revised to identify the land use categories used in the
ALP: aviation, non-aviation, low intensity, and habitat management. Additional land uses that
could be allowed within the aviation and non-aviation areas would be identified, as discussed in
Section 2.6, Proposed Land Uses and Zoning, of this EIR. The Zoning Amendment would specify
that all proposed land uses must be reviewed by County staff for consistency with the current
ALUCP. The zoning would also implement the ALUCP and General Plan standards for compatible
land use, including height restrictions.
As described above, the development of aviation and non-aviation land uses on the airport would
not cause conflicts with the applicable land use plans. The impact would be less than significant.
3.9.5 Mitigation Measures
No mitigation measures are required.
3.9 – LAND USE AND PLANNING
Byron Airport Development Program EIR 9269
February 2022 3.9-13
3.9.6 Level of Significance After Mitigation
No mitigation measures are required. Land use impacts would be less than significant
without mitigation.
3.9.7 Cumulative Impacts
Cumulative impacts for land use may occur if the proposed project, in conjunction with other
projects, would have the potential to create land use conflicts that would not be significant on an
individual basis. More specifically, multiple amendments to the General Plan, ALUCP, or Zoning
Ordinance may create additional conflicts. No projects are proposed that would affect the airport
General Plan designation, ALUCP, or Planned Unit District zoning. Therefore, no cumulative
impacts would occur.

3.10 – NOISE
Byron Airport Development Program EIR 9269
February 2022 3.10-1
3.10 NOISE
This section describes the noise present in the proposed Byron Airport Development Program
(project) area, and discusses applicable federal, state, and regional regulations pertaining to noise.
This section also evaluates the potential effects related to noise associated with development of
the proposed project.
3.10.1 Existing Conditions
This section describes the existing noise conditions in the project area, and also identifies the
existing sensitive receptors that could be affected by the project.
3.10.1.1 Transportation Noise Sources
Aviation
Aircraft operations are the primary noise source emanating from Byron Airport. The most current
airport noise contours are available in the Airport Land Use Compatibility Plan (ALUCP) (Contra
Costa County 2000). Three noise-sensitive residential lots are located in the immediate vicinity of
the airport, and based on the ALUCP, two residences are located within the 55 to 60 A-weighted
decibels (dBA) Community Noise Equivalent Level (CNEL) noise contour. No residential uses
are located within the 60 dBA CNEL contour line. Figure 3.10-1, Noise Contours, shows the Byron
Airport noise contours.
Roadways
Vehicular traffic along Byron Highway is a principal contributor to the existing noise environment
in the vicinity of the project site. Other roads in the vicinity of the project site, including Holey
Road and Byron Hot Springs Road, are existing secondary contributors. Regional access to the
project site is provided by Byron Highway. Access to the main portion of the project site is
provided by Holey Road or Armstrong Road. Noise-sensitive receptors located along these
roadways would experience traffic noise increases due to the proposed project.
3.10.1.2 Other Noise Sources
The project site is mostly undeveloped land that is relatively flat. Surrounding land uses include
rural residential and agricultural/grazing land.
3.10.1.3 Noise-Sensitive Land Uses
Noise-sensitive land uses (NSLUs) are land uses that may be subject to stress and/or interference
from excessive noise. The Noise Element of the Contra Costa General Plan (Contra Costa County
3.10 – NOISE
Byron Airport Development Program EIR 9269
February 2022 3.10-2
2005a) identifies residential areas as one type of NSLU. Industrial and commercial land uses are
generally not considered sensitive to noise, with the exception of commercial lodging facilities.
NSLUs in the immediate vicinity of the project site are as follows:
• Residences located immediately east of the project site along Byron Hot Springs Road and
Holey Road
• Residences along other roadways studied in the Traffic Impact Analysis Report for the
proposed project (Appendix H of this Environmental Impact Report)
3.10.1.4 Vibration-Sensitive Land Uses
Land uses where groundborne vibration could potentially interfere with operations or equipment,
such as research, manufacturing, hospitals, and university research operations (FTA 2006), are
considered “vibration sensitive.” The degree of sensitivity depends on the specific equipment that
would be affected by the groundborne vibration. Excessive levels of groundborne vibration of
either a regular or an intermittent nature can also result in annoyance to occupants of residential
land uses and the structures they inhabit.
3.10.1.5 Existing Noise Levels
Existing (pre-project) noise conditions present in the vicinity of the project site were inventoried
by Dudek in April 2016. Four short-term (varying from 2- to 20-minute durations) measurements
were performed along existing roadways to quantify and help characterize the outdoor ambient
sound environment, likely dominated by roadway traffic, and support calibration of the traffic
noise prediction model. The noise measurement locations are shown in Figure 3.10-2. The results
of the traffic noise measurements are presented in Table 3.10-1. The highest measured average
noise level was associated with traffic on Byron Highway, and was 77 dBA equivalent continuous
sound level (Leq) at a distance of approximately 10 feet from the edge of the pavement. The
measured noise level along Holey Road was 67 dBA Leq at a distance of approximately 23.5 feet
from the centerline of the road on April 12, 2016, and 57 dBA Leq at a distance of approximately
21 feet from the centerline of the road on April 16, 2016. These levels varied based on the duration
of the measurement and the traffic volumes on the road during the measurement. The noise level
along Falcon Way was 64 dBA Leq at approximately 15.5 feet from the road centerline. The noise
level along Armstrong Road was 58 dBA Leq at approximately 23 feet from the road centerline.

a Measurement times varied within the time ranges specified based on traffic.
3.10.2 Relevant Plans, Policies, and Ordinances
Federal
The following federal regulations pertaining to noise would apply to the proposed project.
Federal Aviation Administration Standards
Enforced by the Federal Aviation Administration, Code of Federal Regulations Title 14, Part 150
prescribes the procedures, standards, and methodology governing the development, submission,
and review of airport noise exposure maps and airport noise compatibility programs, including the
process for evaluating and approving or disapproving those programs. Title 14 also identifies those
land uses that are normally compatible with various levels of exposure to noise by individuals. The
Federal Aviation Administration has determined that interior sound levels up to 45 dBA Ldn (or
CNEL) are acceptable within residential buildings. The Federal Aviation Administration also
considers residential land uses to be compatible with exterior noise levels at or less than 65 dBA
Ldn (or CNEL) (49 U.S.C. § 47501et seq, 1979).
Federal Transit Administration and Federal Railroad Administration Standards
Although the Federal Transit Administration (FTA) standards are intended for federally funded
mass transit projects, the impact assessment procedures and criteria included in the FTA Transit
Noise and Vibration Impact Assessment Manual (FTA 2006) are routinely used for projects
proposed by local jurisdictions. The FTA has published guidelines for assessing the impacts of
groundborne vibration associated with transit projects, which have been applied by other
jurisdictions to other types of projects. For example, the FTA guidance threshold for architectural
damage risk pertaining to “engineered concrete and masonry (no plaster)” is 0.3 inches per second
peak particle velocity (ppv), which can be applied when assessing construction-related vibration
impacts upon proximate existing buildings

State
The following state regulations pertaining to noise would apply to the proposed project.
California Noise Control Act of 1973
Sections 46000 through 46080 of the California Health and Safety Code, known as the California
Noise Control Act of 1973, states that excessive noise is a serious hazard to the public health and
welfare, and that exposure to certain levels of noise can result in physiological, psychological, and
economic damage. The California Noise Control Act also identifies a continuous and increasing
bombardment of noise in urban, suburban, and rural areas. The California Noise Control Act states
that the State of California has a responsibility to protect the health and welfare of its citizens by
the control, prevention, and abatement of noise. It is the policy of the state to provide an
environment for all Californians free from noise that jeopardizes their health or welfare.
State Model Community Noise Control Ordinance
Contra Costa County (County) does not have a quantitative noise ordinance for regulating noise
from mechanical equipment or construction. However, a Model Noise Control Ordinance was
created by the State of California to provide guidance for communities to develop their own noise
ordinances. The Model Noise Ordinance has not been adopted by the County and is not enforced
by the state, but it is discussed in this analysis to help provide context for the potential noise
impacts of the proposed project.
The exterior noise level limits recommended by the Model Community Noise Control Ordinance
are shown in Table 3.10-2, Traffic Noise Level Measurements (Existing), and correspond to the
median noise level (L50). The L50 is the sound level in dBA that is met or exceeded 50% of time.
These limits are not to be exceeded at the receiving land use for more than 30 minutes in 1 hour.
The limits are to be adjusted based on the duration of the source, the level of the ambient noise,
the character of the sound, and the location of the measurement.

In addition, the Model Community Noise Control Ordinance provides a noise limit of Ldn 80 dBA
for short-term or intermittent construction activities adjacent to multi-family residential properties,

and a noise limit of Ldn 85 dBA at commercial properties.1 Although the Model Community Noise
Control Ordinance has not been adopted by the County, this reference is provided as context for
assessing the proposed project’s noise levels. Some activity or equipment noise cannot meet this
standard (such as back-up alarms, which are required by state safety regulations).
Local
Contra Costa County Noise Element
The Noise Element of the County General Plan (Contra Costa County 2005a) sets various goals
and policies that apply to all development projects in the County. Most of these policies address
land use compatibility standards for evaluating new projects. Applicable noise goals, policies, and
implementation measures of the Noise Element are as follows (Contra Costa County 2005a):
Goal 11-B To maintain appropriate noise conditions in all areas of the County.
Goal 11-C To ensure the new developments will be constructed so as to limit the effects of
exterior noise on the residents.
Policy 11-1 New projects shall be required to meet acceptable exterior noise
level standards as established in the Noise and Land Use
Compatibility Guidelines contained in Figure 11-6.
Policy 11-2 The standard for outdoor noise levels in residential areas is a DNL
of 60 dB [decibels]. However, a DNL of 60 dB or less may not be
achievable in all residential areas due to economic or aesthetic
constraints. One example is small balconies associated with multi-
family housing. In this case, second and third story balconies may
be difficult to control to the goal. A common outdoor use area that
meets the goal can be provided as an alternative.
Policy 11-6 If an area is currently below the maximum “normally acceptable”
noise level, an increase in noise up to the maximum should not be
allowed necessarily.
1 Ldn stands for day/night level. The Ldn is the average equivalent sound level over a 24-hour period, with a penalty
added for noise during the nighttime hours of 10 p.m. to 7 a.m. During the nighttime period, 10 dB is added to
reflect the impact of the noise.
3.10 – NOISE
Byron Airport Development Program EIR 9269
February 2022 3.10-6
Policy 11-8 Construction activities shall be concentrated during the hours of the
day that are not noise-sensitive for adjacent land uses and should be
commissioned to occur during normal work hours of the day to
provide relative quiet during the more sensitive evening and early
morning periods.
Policy 11-11 Noise impacts upon the natural environment, including impacts
on wildlife, shall be evaluated and considered in review of
development projects.
Figure 3.10-3, Land Use Compatibility Criteria, presents the ranges for acceptable, conditionally
acceptable, and unacceptable noise exposure levels for different land uses in the County pursuant
to General Plan Noise Element Policy 11.1 and Figure 11-6 (Contra Costa County 2005).
The Noise Element also discusses how noise increases are perceived by people (Contra Costa
County 2005a), as follows:
An important factor in assessing a person’s subjective reaction is to compare the
new noise environment to the existing noise environment. In general, the more a
new noise level exceeds the prior existing level, the less acceptable it is. Therefore,
a new noise source will be judged more annoying in a quiet area than it would be
in a noisier location. Knowledge of the following relationships is helpful in
understand how changes to noise and noise exposure are perceived.
• Except under special conditions, a change in sound level of 1 dB cannot be
perceived;
• Outside a laboratory, a 3 dB change is considered a just-noticeable difference;
• A change in level of at least 5 dB is required before any noticeable change
in community response would be expected; and
• A 10 dB change is subjectively heard as an approximate doubling in
loudness and almost always causes an adverse community response.
The following implementation measures related to development review are included in the Noise
Element (Contra Costa County 2005a):
Measure 11-a Continue to require a review and analysis of noise-related impacts as part of the
existing project development review procedures of the County.
3.10 – NOISE
Byron Airport Development Program EIR 9269
February 2022 3.10-7
Measure 11-b Evaluate the noise impacts of a proposed project upon existing land uses in terms
of the applicable Federal, State, and local codes, and the potential for adverse
community response, based on a significant increase in existing noise levels.
Contra Costa County Transportation Element
The following policy related to noise is included in the County General Plan Transportation and
Circulation Element (Contra Costa County 2005b):
Policy 5-68 No residential development or sensitive receptors, e.g. hospitals,
schools, etc., shall be allowed within the projected 60 CNEL noise
contours for the new airport [Byron].
Contra Costa County Municipal Code
The County’s Municipal Code does not contain quantitative standards for regulating noise from
mechanical equipment. However, Section 716-8.1004 of the Municipal Code addresses hours of
operation for excavation and grading activities. If operations under the permit are within 500 feet
of residential or commercial occupancies, except as otherwise provided by conditions of approval
for the project, grading operations are limited to weekdays and to the hours of between 7:30 a.m.
and 5:30 p.m., except that maintenance and service work on equipment may be performed at any
time (Contra Costa County 2018).
Contra Costa County Airport Land Use Compatibility Plan
Chapter 4 of the County ALUCP addresses noise and states that “from a community land use
planning stand-point, noise contours are most appropriately applied at the general plan, specific plan,
or other broad-scale level” (Contra Costa County 2000). Table 4A of the ALUCP describes the
compatibility of various land uses with the different airport noise contours (Figure 3.10-4, Airport
Compatibility Criteria, of the ALUCP). The ALUCP also sets 45 dBA CNEL as the maximum
acceptable interior noise level from aircraft-related activities (Contra Costa County 2000).
3.10.3 Thresholds of Significance
The significance criteria used to evaluate the proposed project’s impacts related to noise are based
on Appendix G of the California Environmental Quality Act (CEQA) Guidelines. According to
Appendix G of the CEQA Guidelines, a significant impact related to noise would occur if the
project would result in:
1. 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.
3.10 – NOISE
Byron Airport Development Program EIR 9269
February 2022 3.10-8
2. Generation of excessive groundborne vibration or groundborne noise levels.
3. 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, and if so, the project would expose people residing or working in the project area
to excessive noise levels.
Contra Costa County Significance Criteria
Noise Significance Criteria
As summarized in Section 3.10.2, Relevant Plans, Policies, and Ordinances, standards established
by the County General Plan Noise Element were used to establish quantitative significance
thresholds with respect to airborne noise. The Noise Element defines noise sensitive areas as
residential areas (Contra Costa County 2005a).
Figure 3.10-3 (corresponding to Figure 11-6 of the Noise Element) identifies the noise
compatibility criteria for various land uses. In addition, Noise Element Policy 11-2 identifies 60
dBA Ldn as the level normally compatible with residential uses. According to the Noise Element,
an increase in outdoor sound level of greater than 10 dB would be expected to cause an adverse
community response. Policy 11-6 states that if an area is currently below the normally acceptable
noise level, an increase up to the maximum should not necessarily be allowed (Contra Costa
County 2005a). Therefore, for assessment of operational noise impacts to the exterior of residential
receptors due to the proposed project, which includes separate consideration of transportation noise
sources and stationary noise sources (e.g., operating heating, ventilation, and air conditioning
[HVAC] systems featured on newly proposed project structures), a project-related increase above
60 dB Ldn or a change of 10 dB in outdoor ambient levels would be a potentially significant impact.
For noise levels inside residences, a threshold of 45 dBA Ldn would be used and would be
compatible with the California Building Code.
For construction activity, per Noise Element Policy 11-8 and County Code Section 716-8.1004,
an expected outdoor ambient level increase of greater than 10 dB or exceeding 60 dBA Ldn would
be a significant impact if occurring outside of the allowable hours of 7:30 a.m. to 5:30 p.m.,
Monday through Friday.
Groundborne Vibration Significance Criteria
In the absence of local regulatory significance thresholds for vibration from construction
equipment, the proposed project uses guidance from the California Department of Transportation
to assess vibration -related impact significance, which includes a vibration limit of 0.3 inches per
second (in/sec) ppv with respect to building damage risk for “older residential structures ,” and
3.10 – NOISE
Byron Airport Development Program EIR 9269
February 2022 3.10-9
0.5 in/sec ppv for “new residential structures” and “modern industrial/commercial buildings”
when continuous or frequent vibration sources are anticipated (Caltrans 2013). For adverse
human reaction, the proposed projected used a “strongly perceptible” annoyance criterion of 0.1
in/sec ppv (Caltrans 2013), consistent with nuisance prevention per Sect ion 716-8.1008 of the
County Municipal Code.
3.10.4 Impacts Analysis
3.10.4.1 Methods of Analysis
The project setting was developed by reviewing available information on noise and sensitive
receptors in the project vicinity. This review was supplemented with noise measurements. Sound
level measurements were performed using a Rion NL-62 integrating sound level meter, which is
classified by the American National Standards Institute as a Type I (precision-grade) device. The
sound level meter was calibrated before each measurement using a Rion NC-74 calibrator.
To evaluate existing and future noise levels from traffic, the CadnaA noise modeling software was
used. CadnaA includes traffic noise algorithms based on the Federal Highway Administration’s
Transportation Noise Model (TNM Version 2.5). The model was first calibrated. Traffic counts
were made during the noise measurements. To calibrate the noise model, the same traffic volume
and vehicle composition ratios counted during the noise measurements were used, along with the
observed vehicle speed (which may differ from the posted speed limit for the roadway). Using
vehicle counts and observed speeds, the modeled noise values were within 2 dB of the measured
noise levels, which confirms the accuracy of the inputs used in the noise model. The proposed
project’s traffic engineers (GHD 2019) provided trip generation data and resulting roadway traffic
volumes for each of the major roadways in the project area for the existing, proposed project, and
cumulative scenarios. The representative existing and proposed future modeled receivers are
shown in Figure 3.10-3. As part of the CNEL calculation process, it was assumed that the average
hourly traffic volume was approximately equal to 10% of the average daily trips.
To assess noise exposure for NSLUs situated along roadways, the analysis used the greatest
anticipated future roadway traffic volume. This is the scenario associated with the cumulative-
plus-project traffic forecast. Using the existing roadway location data and identified future traffic
volumes (from project development and cumulative traffic), traffic noise along each of the main
project-related roadways was modeled with CadnaA. Receptor points in the noise model were
placed at representative existing NSLUs.

Roadway Noise
Off-Site Impacts
Project-generated traffic would have the potential to affect off-site existing NSLUs. Using the
Traffic Impact Analysis Report prepared by the project’s traffic engineers (GHD 2019 [Appendix
H]), the roadway segments with the most project-related traffic trips and with adjacent existing
NSLUs were identified and modeled in CadnaA. These modeling locations are shown in Figure
3.10-5, Noise Modeling Locations. Table 3.10-3, Existing and Cumulative Off-Site Traffic Noise,
summarizes the traffic-related noise levels at the representative off-site NSLUs for existing,
existing plus project, cumulative, and cumulative plus project traffic scenarios. As shown in Table
3.10-3, project-related traffic noise increases would be less than 3 dB (the normal level of
perception) at 10 of the modeled receivers, but not at M1, M2, or M3. At M1, M2, and M3, project-
related traffic noise increases would be 10 dB or greater. For M1, the existing plus project traffic
noise level is predicted to be 60 dBA CNEL, and the existing traffic noise level is 46 dBA CNEL.
For M2, the existing plus project traffic noise level is predicted to be 54 dBA CNEL, and the
existing traffic noise level is 44 dBA CNEL. For M3, the existing plus project traffic noise level
is predicted to be 57 dBA CNEL, and the existing traffic noise level is 47 dBA CNEL.
Per the significance thresholds, an increase of 10 dB or more is significant when ambient noise
levels without the project are less than 60 dBA. Since M1, M2, and M3 would experience an
increase of 10 dB or greater when the project-related traffic is added, the threshold would be
exceeded. These receivers are indicated in Table 3.10-3 in bold. Off-site impacts would be
potentially significant.

Noise from Proposed On-Site Land Uses
Implementation of the project would result in changes to existing noise levels on the project site
by developing new stationary sources of noise and by increasing human activity throughout the
project site. These sources may affect NSLUs adjacent to the project site. Potential noise-
generating land uses on site include commercial and industrial uses.
Commercial
Potential operational noise sources associated with commercial development within the project site
would consist of HVAC equipment, commercial truck deliveries, and noise at surface parking lots.
Mechanical HVAC equipment located on the ground or on rooftops of buildings have the potential
to generate noise levels that average 71 dBA CNEL at a distance of 50 feet when equipment is
operating continuously for 24 hours. Depending on where it is located, HVAC equipment could
have the potential to disrupt nearby residents. For a single point source, such as a piece of
mechanical equipment, the sound level typically decreases by approximately 6 dB for each
doubling of distance from the source under “hard-surface” conditions typical of a developed
commercial site. Therefore, it was assumed that HVAC equipment would generate noise levels
that would exceed 60 dBA Ldn CNEL within approximately 150 feet of the equipment.
Consequently, any proposed HVAC equipment within 150 feet of an existing off-site residence
could result in a potentially significant impact. The nearest off-site residences are located east of
the project site approximately 160 feet or more from proposed project buildings. Therefore,
impacts to off-site receptors related to on-site HVAC equipment would be less than significant.
When back-up alarms are used on site, reference sound pressure levels are anticipated to be 75
dBA at 50 feet (based on Federal Signal Model 252 or similar). The corresponding hourly Leq
would depend on how often such an alarm may be used. Assuming not more than 1 minute per
hour, the resulting sound level would be 57 dBA at 50 feet. Since the closest residences are more
than 100 feet away from the project site, the hourly Leq would less than 51 dBA. Due to the short
duration, the noise impact of back-up alarm operations would be less than significant.
Noise sources from parking lots and storage facilities include car alarms, door slams, radios, and tire
squeals. A noise assessment for the Historic Town Center in the City of San Juan Capistrano provides
typical noise levels for different parking lot events. This source indicates that car door slams and
engine start-ups usually are 60 to 70 dBA at 50 feet, a car alarm noise is between 65 and 70 dBA at
50 feet, and car pass-bys range from 55 to 70 dBA at 50 feet (Mestre Greve Associates 2011). These
sources are generally short-term and intermittent. Noise levels from these typical parking lot noise
sources would be less than 64 dBA at NSLUs located more than 100 feet away. These operations
would result in noise levels less 60 dBA Ldn CNEL due to the short duration and intermittent nature
expected on the project site. Thus, parking lot noise impacts would be less than significant.
3.10 – NOISE
Byron Airport Development Program EIR 9269
February 2022 3.10-13
Construction
Construction of the proposed development would generate noise that could expose nearby
receptors to elevated noise levels that may disrupt communication and routine activities. The
magnitude of the impact would depend on the type of construction activity and equipment, duration
of the construction phase, distance between the noise source and receiver, and intervening
structures. Noise from construction equipment generally exhibits point-source acoustical
characteristics. A point-source sound is attenuated (i.e., reduced) at a rate of 6 dB per doubling of
distance from the source for “hard site” conditions, and 7.5 dB per doubling of distance for “soft
site” conditions. These rules apply to the propagation of sound waves with no obstacles between
source and receivers, such as topography (ridges or berms) or structures. The range of maximum
noise levels for various types of construction equipment is depicted in Table 3.10-4.

equipment (e.g., dozers, loaders, scrapers, miscellaneous trucks) would be used for construction.
Typical operating cycles may involve 2 minutes of full power, followed by 3 or 4 minutes at lower
levels. Special construction techniques such as blasting or pile driving are not anticipated.
The nearest off-site NSLUs to the project site are the residences located immediately adjacent to the
project site on the northeastern site boundary. Although the adjacent residences could be exposed to
elevated construction noise levels, the exposure would be short term and would cease upon
construction completion. It is anticipated that project construction would comply with the County
ordinance limiting noise-generating construction activities to between 7:30 a.m. and 5:30 p.m.,
Monday through Friday. Construction noise impacts would, therefore, be less than significant.
Summary
Project operations would result in substantial traffic-related increases in outdoor ambient noise
levels at three residential locations. This impact would be potentially significant.
Impact 3.10-2. The project would not result in exposure of persons to or generation of excessive
groundborne vibration or groundborne noise levels. (Less than Significant)
Construction of new on-site facilities, such as the proposed warehousing structures located
adjacent to private properties along Armstrong Road, Byron Hot Springs Road, and Holey Road,
would involve operation of heavy construction equipment during allowable daytime hours. The
shortest apparent distance between these construction activities and the nearest inhabited buildings
would be approximately 125 feet (e.g., the apparent farm house associated with the private parcel
at 3773 Armstrong Road). At this distance and per FTA general assessment estimation techniques
that include a reference vibration level of 0.21 in/sec ppv at 25 feet, groundborne vibration from a
vibratory roller operating as close as the project property line would propagate to a level of 0.02
in/sec at the façade of this nearest receptor position. This vibration velocity magnitude does not
exceed the aforementioned 0.3 in/sec ppv for building damage risk or the more stringent 0.1 in/sec
California Department of Transportation-based guidance threshold for human annoyance; thus,
construction activity vibration impacts from the proposed project would be less than significant.
The same vibration-sensitive residential buildings and their occupants discussed above with
respect to proposed project construction vibration are already exposed to potential sources of
groundborne vibration associated with the airport’s existing and on-going general aviation
operations. However, general aviation takeoffs, landings, and taxiing are unlikely to cause
perceptible levels of groundborne vibration velocity impacts due to the relatively long distances
between the runway and taxiways and the nearest inhabited structures on adjoining private
properties. For this reason, groundborne vibration velocity level impacts (and noise due to
excitation of building structural surfaces from this groundborne vibration) associated with
proposed project operation would be less than significant.
3.10 – NOISE
Byron Airport Development Program EIR 9269
February 2022 3.10-15
Impact 3.10-3. The project is located within an airport land use plan and would not expose
people residing or working in the project area to excessive noise levels.
(Less than Significant)
Airport Noise Contours
The noise-sensitive receptors (i.e., residential land uses) that surround the project site are already
exposed to noise levels due to operation of Byron Airport (refer to Figure 3.10-1 for the existing
airport noise contours). The proposed project would not affect general aviation activities or
forecasts. The proposed ALUCP update would not change the Byron Airport noise contours (as
shown in Figure 3.10-6, Proposed ALUCP Noise Policy Map), nor would it change the
compatibility criteria for NSLUs. Additionally, no new noise-sensitive receptors would be
established in the vicinity of the proposed project: the development considered in this project
consists of aviation facilities per the Byron Airport Master Plan, and a potential range of non-
aviation uses, including industrial and commercial uses. Therefore, aircraft noise impacts would
be less than significant.
3.10.5 Mitigation Measures
No feasible mitigation measures have been identified for Impact 3.10-1. Installation of noise walls
is not a feasible mitigation measure in these locations due to the position of the residences and
driveway access.
3.10.6 Level of Significance After Mitigation
Impact 3.10-1 would remain potentially significant, since there are no feasible mitigation
measures to reduce this impact. Residential uses (sensitive receptors) would be exposed to
significant traffic noise due to the project. Traffic noise walls in the vicinity of the impacted
sensitive receptors, while potentially effective, are not feasible due to the location of the receptors.
Thus, traffic noise impacts would be significant and unavoidable. Other operational impacts,
such as commercial activities, would be less than significant.
3.10.7 Cumulative Impacts
Impact 3.10-1 incorporates cumulative traffic volumes to determine the significance of potential
noise impacts. The cumulative effect of traffic noise is potentially significant. Noise walls are not
a feasible mitigation measure in the locations where potentially significant impacts would occur.
Thus, this cumulative traffic noise impact is potentially significant. No other reasonably
foreseeable development would affect temporary or permanent ambient noise levels in the project
vicinity. Aircraft operations at Byron Airport are expected to be consistent with the aviation
3.10 – NOISE
Byron Airport Development Program EIR 9269
February 2022 3.10-16
forecasts relied upon in the ALUCP update. Therefore, all non-traffic cumulative noise impacts
would be less than significant.

3.11 POPULATION, HOUSING, AND GROWTH
This section describes the existing setting of the Byron Airport Development Program (project)
site as it relates to population, housing, and growth; identifies associated regulatory requirements;
and evaluates potential impacts. No mitigation measures are included in this section because no
potentially significant impacts were identified.
3.11.1 Existing Conditions
3.11.1.1 Regional Setting
The project site is located in eastern Contra Costa County (County), which includes the cities of
Pittsburg, Antioch, Oakley, and Brentwood. The southeastern area where Byron Airport is located
includes the unincorporated communities of Byron and Discovery Bay. The unincorporated
eastern part of the County is mainly rural, with the exception of the Town of Discovery Bay
(Discovery Bay). The nearest community to the project site is Byron, which had a 2010 population
of 1,277 (U.S. Census Bureau 2010). Population trends for the County, including the eastern
County subarea, are shown in Table 3.11-1, Population Growth Trends.

Source: Contra Costa County 2014.
Since 2000, the cities in the eastern part of the County have experienced massive population
growth. This is particularly true for Brentwood, whose population grew 251% from 2000 to 2017.
Most growth in the unincorporated east County area has occurred in Discovery Bay, where
subdivisions approved in the 1990s are still being built (Contra Costa County 2014).
3.11 – POPULATION, HOUSING, AND GROWTH
Byron Airport Development Program EIR 9269
February 2022 3.11-2
Unemployment for the communities of Byron and Discovery Bay is shown in Table 3.11-2,
Unemployment Rate. Note the available Census data likely overstates the unemployment rate, due
to the recession of 2008. Employment opportunities in the unincorporated east County area exist
mainly in the agriculture, service, and construction sectors.

3.11.1.2 Project Site
One single-family residence is located within the project site, on the parcel proposed for
acquisition at 3790 Armstrong Road. Properties adjacent to Byron Airport are used for agriculture
or open space, with scattered rural residences.
3.11.2 Relevant Plans, Policies, and Ordinances
3.11.2.1 Federal
There are no federal laws or regulations addressing population, employment, or housing that are
relevant to the proposed project.
3.11.2.2 State
California State Aeronautics Act
The purpose of the California State Aeronautics Act pursuant to Public Utilities Code (PUC)
Section 21001 et seq. “is to protect the public interest in aeronautics and aeronautical progress.”
The California State Aeronautics Act provides for the creation of an Airport Land Use Commission
(ALUC) for every county that contains a public-use airport. The purpose of an ALUC, per the
California State Aeronautics Act, is to conduct airport land use compatibility planning. ALUCs
protect public health, safety, and welfare by ensuring the orderly growth of airports and adoption
of land use measures that minimize the public’s exposure to excessive noise and safety hazards
within areas around public airports to the extent that these areas are not already devoted to
incompatible uses (PUC Sections 21670–21679.5). The primary mechanism used to accomplish
airport land use compatibility planning is adoption of an Airport Land Use Compatibility Plan
(ALUCP) (PUC Sections 21674[c] and 21675).

Byron Airport Development Program EIR 9269
February 2022 3.11-3
3.11.2.3 Local
Airport Land Use Compatibility Plan
The Contra Costa County Airport Land Use Compatibility Plan, adopted in 2000, is discussed in
Section 3.9, Land Use and Planning. The Airport Land Use Compatibility Plan restricts residential
development within the Airport Influence Area.
Contra Costa County General Plan
The County General Plan contains goals, policies, and implementation measures applicable to
development projects in the unincorporated areas of the County. The Housing Element contains
nine goals and 29 policies related to production of new housing, maintenance of existing housing
stock, and expansion of housing opportunities (Contra Costa County 2014). Since residential
development is not considered a compatible land use on the project site, these goals and poli cies
are not applicable to the project or Byron Airport.
The County General Plan Land Use Element contains the following goals and policies that relate
to economic development and are applicable to the proposed project (Contra Costa County 2005a):
Goal 3-D To provide for a range and distribution of land uses that serve all social and
economic segments of the county and its subregions.
Goal 3-K To develop a balance between job availability and housing availability with
consideration given to wage levels, commute distance, and housing affordability.
Policy 3-2 Job infill shall be supported and stimulated where the jobs/housing
ratio shows an overabundance of housing to jobs.
Policy 3-3 As feasible, areas experiencing rapid urban growth shall be
developed so as to provide a balance of new residential and
employment opportunities.
Policy 3-30 A variety of appropriately sized, well-located employment areas
shall be planned in order that industrial and commercial activities
can contribute to the continued economic welfare of the people of
the county and to the stable economic and tax bases of the county
and the various cities.
Policy 3-41 The continuing orderly development of research facilities, regional
offices, and light industrial uses shall be encouraged in designated areas
in order to improve the economic base and provide local employment.
3.11 – POPULATION, HOUSING, AND GROWTH
Byron Airport Development Program EIR 9269
February 2022 3.11-4
Policy 3-42 Industrial development shall be concentrated in select locations
adjacent to existing major transportation corridors and facilities.
Policy 3-44 Industries which employ the skills of county residents shall be
encouraged to locate within the county.
The County General Plan Transportation and Circulation Element contains the following policies
regarding growth around Byron Airport that are applicable to the proposed project (Contra Costa
County 2005b):
Policy 5-64 The County shall acquire fee title and/or conservation (development
rights) easements to an appropriate amount of buffer land around
Byron Airport.
Policy 5-65 The buffer land or conservation easements acquired around the
airport shall ensure that incompatible uses will not be allowed to
locate within the safety zone.
Policy 5-66 Establishment of commercial, industrial, or residential development
around the planned airport shall not be allowed.
Policy 5-67 Water and sewer services to the airport will be limited to serve only the
airport property; utilities will not serve growth on the adjacent properties.
Policy 5-68 No residential development or sensitive receptors, e.g., hospitals,
schools, shall be allowed within the projected 60 CNEL noise
contours for the airport.
Policy 5-77 The following are suggested uses within the ALUC Compatibility
Zones for Byron Airport: agriculture; open space; low-intensity park
and recreation uses; low occupant density public uses; and parking
of automobiles.
3.11.3 Thresholds of Significance
The significance criteria used to evaluate the project’s impacts are based on Appendix G of the
California Environmental Quality Act Guidelines. According to Appendix G, a significant impact
related to population and housing would occur if a project would:
1. Induce substantial unplanned population growth in an area, either directly (for example, by
proposing new homes and businesses) or indirectly (for example, through extension of
roads or other infrastructure).
3.11 – POPULATION, HOUSING, AND GROWTH
Byron Airport Development Program EIR 9269
February 2022 3.11-5
2. Displace substantial numbers of existing people or housing, necessitating the construction
of replacement housing elsewhere.
The project would include an update to the ALU CP. Therefore, the following additional issue
is considered:
3. Would the project result in the substantial displacement of planned housi ng that would
necessitate the construction of additional housing elsewhere?
3.11.4 Impacts Analysis
Impact 3.11-1. The project would not induce substantial unplanned population growth in
the area, either directly or indirectly. (Less than Significant)
The project does not propose new residential land uses. The current and proposed General Plan
policies and zoning do not permit residential land uses on the airport property. The project would
expand aviation uses and airport-related industrial and commercial development consistent with
the Airport Master Plan. Additional employment opportunities at the project site could slightly
increase the demand for housing in the region. However, it is anticipated that most of the jobs
would be filled by people living in the area, since the eastern County area has a large workforce.
As noted in the County General Plan Housing Element, the County provides “bedroom
communities” for the workforce of other Bay Area counties (Contra Costa County 2014). New
employment opportunities at Byron Airport would help to address the imbalance of jobs and
housing in the County, and particularly in the eastern County subregion. Overall, the impact on
housing and population growth would be less than significant.
Impact 3.11-2. The project would not displace substantial numbers of existing people or
housing, necessitating the construction of replacement housing elsewhere.
(Less than Significant)
No residential uses are located on the airport property. The project would include potential
acquisition and demolition of one single-family residence on an adjacent property. This would be
a willing sale by the owner and would not displace a substantial number of people. The impact
would be less than significant.
Impact 3.11-3. The project would not result in the substantial displacement of planned
housing that would necessitate the construction of additional housing
elsewhere. (No Impact)
Consistent with state guidance, ALUCPs generally discourage or prohibit residential units within
certain safety zones in Airport Influence Areas. This planning principle is based on the goal of
3.11 – POPULATION, HOUSING, AND GROWTH
Byron Airport Development Program EIR 9269
February 2022 3.11-6
protecting the safety of people living near airports and the airplane passengers and crew (by
avoiding dense residential areas near air traffic patterns). Local general plans, specific plans, and
zoning ordinances are required by the California State Aeronautics Act to be consistent with the
ALUCP. Therefore, planned residential uses and densities should be consistent with the ALUCP.
When an ALUCP is amended or updated to reduce allowed residential uses, these changes should
be reflected in local plans and ordinances, which could reduce the number of future residential
units within the Airport Influence Area. The regional need for housing would then increase demand
in areas where residential density is not constrained by the ALUCP. This is commonly referred to
as “displacement.” Potential unplanned growth in areas where displacement occurs could result in
significant effects to the environment.
The current ALUCP for Byron Airport restricts residential development, with no residential uses
allowed within the runway protection zone and allowable density increasing as distance from the
approach/departure zone increases. The proposed ALUCP update would revise the safety zones to
be more consistent with current state guidance, including minor changes in the shape of the zones,
and a relaxation of commercial and industrial use restrictions. Residential density standards,
however, would not be relaxed. Table 3.11-3 shows the current and proposed residential standards.

a One residential unit may be developed on an existing lot. No residential subdivisions are permitted.
As shown, no additional limitations would be placed on residential units in the proposed ALUCP.
In addition, no changes to the General Plan land use designations or zoning designations for the
properties surrounding Byron Airport are proposed. The areas around the airport are designated
“Agricultural Lands” in the General Plan and zoned primarily for agricultural use (see Figure 3.9-
3, Existing Zoning, of Section 3.9 of this Environmental Impact Report). The minimum parcel
sizes for agricultural districts are 5 acres (A-2 Zone), 10 acres (A-3 Zone), or 40 acres (A-4 Zone).
These zones are as, or more, restrictive than the recommended densities in the ALUCP update.
3.11 – POPULATION, HOUSING, AND GROWTH
Byron Airport Development Program EIR 9269
February 2022 3.11-7
Therefore, planned residential densities would not be reduced, and no displacement would occur.
There would be no impact related to housing displacement.
3.11.5 Mitigation Measures
No mitigation is required.
3.11.6 Level of Significance After Mitigation
The proposed project’s impacts related to population, housing, and growth would be less than
significant without mitigation.
3.11.7 Cumulative Impacts
Cumulative impacts to population and housing would result from a combination of projects that
induce population growth. As described in Section 3.11.4, Impacts Analysis, for Impact 3.11-1,
the project does not propose residential land uses, and these uses are not permitted on airport
property by the current or proposed General Plan policies and zoning. Additional employment
opportunities at the project site could slightly increase the demand for housing in the region.
However, it is anticipated that most of the jobs produced by the project would be filled by people
living in the area, since the eastern part of the County has a large workforce. Residential
development within the County has the highest potential to result in population growth in the area.
Section 6.2, Housing Needs Assessment, of the County’s General Plan Housing Element identifies
the nature and extent of housing needs for current and future residents of the County. This section
of the General Plan quantifies the share of the region’s housing growth that has been allocated to
the County. This estimate is based on projected household growth, the amount of units needed to
account for the normal and appropriate level of vacancies, and the replacement of units lost to
conversion or demolition (Contra Costa County 2014). In 2013, the Association of Bay Area
Governments completed a Regional Housing Needs Assessment (RHNA) for 2015–2023, which
provides a breakdown of the County’s share of future regional housing needs by four income
categories: very low, low, moderate, and above moderate. The RHNA determined that over the
2015–2023 period, the total housing need within the County would be 20,630 new units. Of this,
1,367 new units would be needed within the unincorporated areas of the County (ABAG 2013).
The County has already planned for required new units in the County, and is required to identify
sites available for new housing development to meet the RHNA. There are no planned
developments in the eastern part of the County in excess of the County’s RHNA goals (ABAG
2013; Contra Costa County 2014). Therefore, there would be no cumulative impact related to
substantial unplanned population growth.
Because the project site would not displace substantial numbers of existing people or housing
necessitating the construction of replacement housing elsewhere, the project would not result in
3.11 – POPULATION, HOUSING, AND GROWTH
Byron Airport Development Program EIR 9269
February 2022 3.11-8
cumulative impacts related to displacement (see Impact 3.11-2). Additionally, the project would
not result in changes to the General Plan land use designations or zoning designations for the
properties surrounding Byron Airport. Therefore, the project would not change planned residential
densities surrounding the site, and no displacement would occur (see Impact 3.11-3). The proposed
project would have no cumulative impacts related to displacement of housing or people.

February 2022 3.12-1
3.12 PUBLIC SERVICES
This section describes the existing setting of the Byron Airport Development Program (project)
site as it relates to public services, identifies associated regulatory requirements, and evaluates
potential impacts. No mitigation measures are included in this section because no potentially
significant impacts were identified.
3.12.1 Existing Conditions
3.12.1.1 Fire Protection and Emergency Medical Services
Fire protection for the project site and its vicinity is provided by the East Contra Costa Fire
Protection District (ECCFPD). The ECCFPD serves approximately 249 square miles with three
fire stations staffed by three firefighters each, for a total district staffing of nine firefighters per
day (ECCFPD 2019a). The closest fire station to the project site is Station 59 located
approximately 8 miles (driving distance) north on Bixler Road in the Town of Discovery Bay
(Discovery Bay) (Aubert 2019). The other two stations are located in Brentwood and Oakley.
ECCFPD’s divisions, which include the Fire Suppression/Operations Division,
Training/EMS/Safety Division, Public Education Division, Fire Prevention Division, and
Hazardous Waste Management Division, are supervised by one fire chief. The largest division
within the ECCFPD is the Fire Suppression/Operations Division, which provides emergency
medical services, fire suppression, rescue, hazardous conditions response, and all other emergency
and non-emergency calls for service. In January 2019, the ECCFPD received 689 calls for service,
with an average response time of 8 minutes. Notably, only two of these calls were for major calls
for commercial structural fires (ECCFPD 2019b). At this time, the ECCFPD is budgeted for 36
personnel, and 35 of these positions are filled. ECCFPD personnel include one fire chief, three
administration personnel, four battalion chiefs, nine captains, nine engineers, and nine firefighters
(ECCFPD 2019a, 2019b). The Contra Costa County (County) Airports Division also maintains an
aircraft rescue and firefighting truck at Byron Airport.
3.12.1.2 Law Enforcement
Law enforcement services at the project site are provided by the County Sheriff’s Office. The
Sheriff’s Patrol Division provides uniformed law enforcement services to greater than 1 million
residents over 715 miles in the County. The station house closest to the project site is Delta Station,
located at 210 O’Hara Avenue in Oakley. The Delta Station serves the eastern part of the County,
including the unincorporated areas around Antioch, Oakley, and Brentwood, and the communities
of Bethel Island, Knightsen, Byron, and Discovery Bay. The station includes 23 sworn staff
positions, including one lieutenant (station house commander), five sergeants; 15 beat deputies,
and two special district deputies. The station also has non-sworn staff consisting of two community
services officers and one crime prevention specialist. Non-sworn staff consists of two community
3.12 – PUBLIC SERVICES
Byron Airport Development Program EIR 9269
February 2022 3.12-2
services officers and one crime prevention specialist (Contra Costa County Sheriff’s Office 2019).
The Sheriff’s Office also operates the Discovery Bay Annex, staffed by two deputies and one crime
prevention specialist, located on Discovery Bay Boulevard. Local funding for the Sheriff’s Office
comes from the County’s general fund and special tax assessment areas.
3.12.1.3 Schools
The project site is served by the Byron Union School District and Liberty Union High School
District. The closest schools to the project site are Byron Elementary and Excelsior Middle, which
share a campus approximately 3 miles north (BUSD 2019).
3.12.1.4 Parks and Recreation Facilities
The County Public Works Department manages numerous parks and recreation facilities within
the County. The County’s parks system also consists of several regional park districts, including
the East Bay Regional Park District. The County also includes more than 1,200 miles of hiking
trails (Contra Costa County 2019). The East Bay Regional Park District spans Alameda and Contra
Costa Counties and contains approximately 121,397 acres in 73 regional parks, including more
than 1,250 miles of trails. Recreational opportunities offered in these parks include hiking, biking,
picnicking, horseback riding, camping, fishing, boating, golfing, and nature study (EBRPD 2019).
There are no general recreation parks in the unincorporated community of Byron, but several
general recreation parks are located in Discovery Bay to the north. Additionally, the Bethany
Reservoir State Recreation Area is 2.5 miles south of the project site.
3.12.1.5 Library Services
The County Library provides 26 library branches throughout the County. The project site is served
by the Discovery Bay Library Connection, which is a service of the County Library. The library
branch closest to the project site is the Brentwood Library, located approximately 7.5 miles north.
3.12.2 Relevant Plans, Policies, and Ordinances
This section describes applicable federal, state, and local laws, regulatory guidance, and policies
that govern public services in the County.

Federal
Federal Fire Prevention and Control Act of 1974/Federal Fire Safety Act of 1992
The Federal Fire Prevention and Control Act of 1974 was created to provide federal assistance to
states and communities for research and development, education, and training on fire problems ;
setting priorities; and identifying possible solutions to problems. The 1974 act was amended in
1992 by the Federal Fire Safety Act of 1992 to require, among other things, automatic sprinkler
systems or an equivalent level of safety on buildings having more than 25 employees that have
been purchased, constructed, or renovated with federal funds.
National Fire Protection Association Codes and Standards
The National Fire Protection Association is a membership organization that develops and monitors
the use of more than 300 fire codes and standards that have been widely incorporated into state
and local fire codes. There are no legislative enforcement mechanisms in place. By working
through numerous technical committees, the National Fire Protection Association uses a consensus
approach to solve many safety-related issues. The National Fire Protection Association standards
are updated every 3 to 5 years (NFPA 2018).
State
State Fire Regulations
The California Fire Code (CFC) is Part 9 of Title 24 of the California Code of Regulations, which
includes regulations concerning building standards (as also set forth in the California Building
Code), fire protection and notification systems, fire protection devices such as extinguishers and
smoke alarms, high-rise building and childcare facility standards, and fire suppression training. It
was created by the California Building Standards Commission and is based on the International
Fire Code created by the International Code Council. It is the primary means for authorizing and
enforcing procedures and mechanisms to ensure the safe handling and storage of any substance
that may pose a threat to public health and safety. The CFC regulates the use, handling, and storage
requirements for hazardous materials at fixed facilities. The CFC and the California Building Code
use a hazard classification system to determine what protective measures are required to protect
fire and life safety (24 CCR Part 9). These measures may include construction standards,
separations from property lines, and specialized equipment. To ensure that these safety measures
are met, the CFC employs a permit system based on hazard classification. The CFC is updated
every 3 years and was most recently updated in 2016, with an effective date of January 1, 2017.

California Senate Bill 50, the School Facilities Act of 1998, and the bond procedures under
Proposition 1A of 1998 amended state law to reform school facilities financing and to set the
California Environmental Quality Act (CEQA) standards for mitigation for school facilities. As
amended by Senate Bill 50, California Education Code Section 17620 authorizes school districts
to levy a fee against new development, including residential and non-residential, within the school
district to fund construction, reconstruction, and/or modernization of school facilities. The school
district must demonstrate the need for school construction or reconstruction, and demonstrate that
the fee does not exceed the cost of construction or reconstruction necessary to meet this need.
Senate Bill 50 also amended California Government Code Sections 65966–65968 to prohibit a
local agency from either denying approval of a land use project because of inadequate school
facilities or imposing school impact mitigation measures other than the designated fees provided
for in the Education Code. However, in any year that a proposed statewide bond measure for K–
12 school facilities fails, Senate Bill 50 would permit a local agency to deny a development project
requiring legislative approval on the basis of inadequate school facilities.

Quimby Act
In 1975, the Quimby Act (California Government Code Section 66477, as amended in 1982)
granted cities and counties authority to pass ordinances requiring developers to set aside land,
donate conservation easements, or pay in-lieu fees for park improvements. The goal of the Quimby
Act was to require developers to help mitigate the impacts of their developments. Special districts
must work with cities and counties to receive parkland dedication and/or in-lieu fees. The fees
must be paid and land conveyed directly to the local public agencies that provide park and
recreation services to the affected community. Revenues generated through the Quimby Act cannot
be used for operation and maintenance of park facilities.

Goal 9-H To develop a sufficient amount of conveniently located, properly designed, park
and recreational facilities to serve the needs of all residents.
Goal 9-I To develop a system of interconnected bicycle, pedestrian, and riding trails and
paths suitable for both active recreational use and transportation/circulation.
Goal 9-J To promote active and passive recreational enjoyment of the County’s physical
amenities for the continued health, safety, and welfare of the citizens of the County.
Goal 9-K To achieve a level of park facilities of four acres per 1,000 population.

library service standards are not being met.
3.12.3 Thresholds of Significance
The significance criteria used to evaluate impacts to public services are based on Appendix G of the
CEQA Guidelines. A significant impact related to public services would occur if a project would:
1. Result in substantial adverse physical impacts associated with the provision of new or
physically altered governmental facilities, or 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.
3.12 – PUBLIC SERVICES
Byron Airport Development Program EIR 9269
February 2022 3.12-9
b. Police protection.
c. Schools.
d. Parks.
e. Other public facilities.
3.12.4 Impacts Analysis
Impact 3.12-1 The project would not result in substantial adverse physical impacts
associated with the provision of new or physically altered governmental
facilities, or the 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. (Less than Significant)
Fire Protection
The ECCFPD provides fire protection services and emergency medical services to approximately
249 square miles within the County, including the project site. The ECCFPD has three fire stations
staffed by three firefighters, for a total district staffing of nine firefighters per day. In addition, the
ECCFPD is served by one fire chief, three administration personnel, four battalion chiefs, nine
captains, and nine engineers (ECCFPD 2019a, 2019b). ECCFPD’s Master Plan estimates that nine
stations would be needed to provide coverage to ECCFPD’s citizens and businesses in the long
term (ECCFPD 2016). Additionally, the ECCFPD strictly enforces the County Fire Code (the
California Fire Code with County-specific amendments), which provides strict requirements for
fire suppression systems, use of fire-resistant building materials, and use of visible address
signage. The nearest fire station to the project site is Station 59, which is located approximately 8
miles to the north.
The project site consists of four separate development areas: aviation, non-aviation, low-intensity use,
and habitat management. Proposed land uses in the aviation area include airport infrastructure, hangars,
fixed-base operators, businesses that directly support aviation and travel, and businesses that rely on
aviation. Approximately 46.6 acres would support non-aviation uses, which includes commercial and
light-industrial uses that are compatible with airport operations and would benefit from being located
at an airport. Low-intensity-use areas and habitat management lands would not include any buildings
or structures. Section 3.11, Population, Housing, and Growth, of this Environmental Impact Report
(EIR) determined that the proposed project would not cause substantial population growth within the
area, since the project would not include new residential land uses and would not increase demand for
housing in the region. Most calls for service are residential calls, including emergency medical service
(ECCFPD 2019b). Project elements would comply with federal, state, and local requirements
3.12 – PUBLIC SERVICES
Byron Airport Development Program EIR 9269
February 2022 3.12-10
regarding fire protection, including California Government Code Section 51182 and Public Resources
Code Section 4291, which would reduce fire hazards to buildings and structures. Byron Airport
maintains its own water system for fire suppression, which would be expanded prior to any airport-
related industrial or commercial development.
An ECCFPD study concluded that to adequately provide service to eastern Contra Costa County,
additional staff and facilities would be required (ECCFPD 2016). In particular, additional stations
should be located in Discovery Bay and Brentwood. The most recent Municipal Service Review
prepared by the County Local Agency Formation Commission noted that the primary hurdles to
achieving better levels of service were a lack of an adequate property tax base and a lack of
alternative funding sources (Contra Costa County LAFCO 2016). The proposed project would
provide needed tax revenue (with private airport-related development on County property). New
development on site would also meet current fire codes, reducing additional demand for fire
protection services. Additional tax revenues would assist with funding of ECCFPD staff and
facilities. The potential construction and expansion of ECCFPD facilities would occur within the
urban areas of Discovery Bay and Brentwood. Impacts of such development would be consistent
with the County General Plan and Brentwood General Plan. There is no substantial evidence that
the construction of future planned fire facilities would have a significant effect on the environment.
Impacts related to fire protection would be less than significant.
Police Protection
The County Sheriff’s Office provides law enforcement services within the County. The nearest
County Sheriff’s station to the project site is Delta Station, located approximately 12.2 miles
northwest in Oakley. Although the project would expand aviation and non-aviation uses at the site,
which would increase the number of people on the site, the project would not include residential
uses that would cause substantial population growth in the County. Furthermore, the project would
primarily employ people residing in the region and would not substantially increase demand for
housing or result in population growth (see Section 3.11 of this EIR). Population is used by the
Sheriff’s Office to determine the need for new or expanded facilities (General Plan Policy 7-57;
Contra Costa County 2005a). The project is not expected to increase demand for police protection
services such that new or expanded facilities would be required. Impacts related to police
protection would be less than significant.
Schools
The project would not include residential uses. Although additional employment opportunities at
the project site could induce slight population growth in the eastern part of the County, it is
anticipated that most of the jobs would be filled by people already living in the area, since the
region has a large workforce. Nevertheless, private development at the project site would pay
3.12 – PUBLIC SERVICES
Byron Airport Development Program EIR 9269
February 2022 3.12-11
impact fees to the Byron Union School District and Liberty Union High School District. These
fees are intended to mitigate for this type of development. Impacts related to school facilities would
be less than significant.
Parks
The County Public Works Department provides park and recreational services to the
unincorporated County, including the project site. The project would not involve development of
residential uses or result in a direct or indirect population growth that would, in turn, increase
demand on regional parks and open spaces. Therefore, impacts related to parks and recreational
resources would be less than significant.
Library Facilities
The County Library provides library services to the project site. The proposed project would not
involve development of residential uses, and would not result in a direct or indirect population
growth that would, in turn, increase demand on regional libraries. Therefore, impacts related to
libraries facilities would be less than significant.
3.12.5 Mitigation Measures
No mitigation is required.
3.12.6 Level of Significance After Mitigation
The project’s impacts related to public services would be less than significant without mitigation.
3.12.7 Cumulative Impacts
The context for cumulative service impacts is the eastern part of the County and growth evaluated
in the County General Plan. The project would not include residential uses, and would therefore
not contribute to a substantial increase in population that would increase demands for schools,
parks and recreation facilities, or library facilities. The project would allow for aviation and non-
aviation uses that would require fire and police protection for property and employees. The County
General Plan states that new stations would be required in the County and additional equipment
would be required at existing stations to maintain an acceptable level of service for fire protection
(Contra Costa County 2005a). Furthermore, the County General Plan EIR concluded that build-
out of the General Plan would result in the need for increased police protection staff and equipment
to maintain acceptable service ratios (Contra Costa County 2005c). The County General Plan
includes policies to address the effects of growth, including a requirement that new development
pay its fair share of costs for new fire and police protection facilities and services. The General
Plan EIR concluded that, with implementation of the General Plan policies, the impacts of
3.12 – PUBLIC SERVICES
Byron Airport Development Program EIR 9269
February 2022 3.12-12
expanded fire and police protection facilities would be less than significant (Contra Costa County
2005c). The proposed project would not contribute to growth inconsistent with the General Plan,
and would not contribute to a cumulative impact that is not addressed by existing policies.
Therefore, cumulative impacts would be less than significant.

3.13 TRANSPORTATION
This section describes the existing transportation setting of the Byron Airport Development
Program (project) site, identifies associated regulatory requirements, evaluates potential impacts,
and identifies mitigation measures related to implementation of the proposed project.
This section is based on the Transportation Impact Analysis (TIA) Report prepared by Dudek for
the proposed project (April 2021). A complete copy of the Transportation Impact Analysis Report
is included as Appendix H of this Environmental Impact Report (EIR). The TIA for the project
has been prepared per Contra Costa County Transportation Analysis Guidelines (TAG) (June
2020) which establishes the approach and methodology to evaluate project impacts on the
County’s transportation system using vehicle miles traveled (VMT) for CEQA and the level of
service (LOS) metric for General Plan consistency requirements. This section uses VMT as the
basis for evaluating transportation impacts under CEQA, consistent with CEQA Guidelines
Section 15064.3. The project’s effects on LOS are included in the TIA (Appendix H) for the
proposed project.
3.13.1 Transportation Setting
This section describes the existing transportation network in the vicinity of the project site,

Transit System
Eastern Contra Costa Transit Authority (Tri Delta) Tri Delta Transit serves the eastern parts
of Contra Costa County (CCTA 2019). However, there are no transit systems near the project site.
The nearest Tri Delta Transit bus service is located north of the project area in the City of
Brentwood. Routes 385, 391 and 393 operate and provide service at the nearest bus stop.
Route 385 operates between Brentwood Park and Ride and Antioch BART Station via Slatten
Ranch Shopping Center. The service is currently available on weekdays only at a frequency of
approximately an hour throughout the day.
Route 391 operates between Brentwood Park & Ride and Pittsburg Center Station. The service is
currently available on weekdays only at a variable frequency between 25 minutes to an hour
throughout the day.
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-4
Route 393 operates between Brentwood Park & Ride and Antioch BART Station. The service is
currently available on weekends only at a frequency of approximately an hour throughout the day.
TRACER The City of Tracy offers seven fixed bus routes. Routes A, B, and F operate along Grant
Line road; however, no routes extend past the City limits to service areas near the project site.
The nearest passenger train service, including Bay Area Rapid Transit (BART) and Amtrak, is
located in the City of Antioch to the north.
There are no other transit system facilities that service the project area. Figure 3.13.2 identifies the
nearest transit facilities within the study area.
Bicycle and Pedestrian Facilities
The Contra Costa Countywide Bicycle & Pedestrian Plan (CBPP) (CCTA 2018) identifies the
following bicycle facility classifications and descriptions:
• Shared-Use Path (Class I Bikeway) – Bike paths provide a completely separate right of
way that is designated for the exclusive use of people riding bicycles and walking with
minimal crossflow traffic.
• Bike Lane (Class II Bikeway) – Using special lane markings, pavement legends, and
signage, bike lanes provide designated street space for bicyclists, typically adjacent to the
outer vehicle travel lanes.
• Buffered Bike Lanes (Class II Bikeway) – Increase separations through painted buffers
between vehicle lanes and/or parking, and green paint at conflict zones (such as driveways
or intersections).
• Bike Route (Class III bikeway) – Provide enhanced mixed-traffic conditions for
bicyclists through signage, sharrow striping, and/or traffic calming treatments, and provide
continuity to a bikeway network.
• Bicycle Boulevards (Class III Bikeway) – Further enhanced bike routes by encouraging
slower speeds and discouraging non-local vehicle traffic using traffic diverters, chicanes,
traffic circles, and speed tables.
• Protected Bikeway (Class IV Bikeway) – Referred to as cycle tracks or separated
bikeways, these are set aside for the exclusive use of bicycles and physically separated
from vehicle traffic with vertical separation, including grade separation, flexible posts,
physical barriers, or on-street parking.
In addition to the above classifications, the CBPP further categorizes existing and proposed bicycle
facilities through a Level of Traffic Stress (LTS) analysis, which assigns a LTS score to the bicycle
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-5
facility depending on the perceived stress of the cyclist. A brief description of each LTS score is
provided below, as defined in the CBPP. Low traffic stress correlates with a LTS score of 1 or 2,
and high traffic stress correlates with a LTS score of 3 or 4.
• LTS 1 – Physically separated from traffic or low-volume, mixed-flow traffic at 25 mph or
less; bike lanes are six-feet wide or more;
• LTS 2 – Bicycle lanes are 5.5-feet wide or less, next to 30 mph auto traffic; unsignalized
crossings of up to five lanes at 30 mph;
• LTS 3 – Bicycle lanes next to 35 mph auto traffic, or mixed-flow traffic at 30 mph or less;
• LTS 4 – No dedicated bicycle facilities; traffic speeds 40 mph or more.
In the study area, Marsh Creek Trail, a shared-use path (Class I Bikeway), runs north of Concord
Avenue from Creek Road to Central Boulevard, and is approximately 10 miles northwest from the
project site. Marsh Creek Trail bikeway can be accessed via Marsh Creek Road, south of Concord
Avenue. Currently, there are no bicycle facilities along Marsh Creek Road; however, the CBPP
has planned bicycle facilities for Byron Highway, Camino Diablo, Bixler Road, Byer Road, and
SR-4. Currently, these roadways do not have designated bicycle facilities. Figure 3.13-2, identifies
existing and planned regional bicycle facilities in the project vicinity.
Local Bicycle Network in the County is shown on Figure 3.13-3. Per CBPP, Class II bicycle lanes
are proposed along Byron Hot Springs Road and Holey Road from project site to Byron Highway.
The local bicycle network would connect to the low-stress bikeway (Class II) proposed along
Byron Highway.
The San Joaquin County Bicycle Master Plan also identifies similar bicycle facilities to those noted
above, including Class I Shared Use Paths, Class II Bicycle Lanes, Class II Buffered Bicycle
Lanes, and Class III Bicycle Routes (San Joaquin County 2020). The Mountain House community
area includes several Class III Bicycles Routes; however, no other San Joaquin County bicycle or
pedestrian facilities are located near the project site.
Currently, there are no pedestrian facilities within the project vicinity. Due to the lack of
connectivity and significant development in the immediate project vicinity, pedestrian activity is
very light. Long-range planning for Byron Highway includes possible pedestrian facilities in terms
of sidewalks and a Class I multi-use path (Appendix H).

The Federal Aviation Administration’s primary role is to promote aviation safety and control the use
of airspace. The Federal Aviation Administration enforces safety standards and investigates and
corrects violations as appropriate. Federal regulations applicable to compatible land use include
Federal Aviation Regulation Part 77: Safe, Efficient Use, and Preservation of the Navigable
Airspace, and 14 Code of Federal Regulations Part 150 Airport Noise Compatibility Planning.
State
Senate Bill 743
On September 27, 2013, Governor Brown signed SB 743, which became effective on January 1,
2014. The purpose of SB 743 is to streamline the review under the CEQA process for several
categories of development projects including the development of infill projects in transit priority
areas and to balance the needs of congestion management with statewide goals related to infill
development, promotion of public health through active transportation, and reduction of
greenhouse gas emissions. SB 743 adds Chapter 2.7: Modernization of Transportation Analysis
for Transit Oriented Infill Projects to the CEQA Statute (Public Resources Code Section 21099).
Section 21099(d)(1) provides that aesthetic and parking impacts of a residential, mixed-use
residential, or employment center project on an infill site within a transit priority area shall not be
considered significant impacts on the environment. In addition, SB 743 mandates that alternative
metric(s) for determining impacts relative to transportation shall be developed to replace the use
of LOS in CEQA documents.
In the past, environmental review of transportation impacts focused on the delay that vehicles
experience at intersections and on roadway segments, which is often measured using LOS.
Mitigation for impacts on vehicular delay often involves increasing capacity such as widening a
roadway or the size of an intersection, which in turn encourages more vehicular travel and greater
pollutant emissions. Additionally, improvements to increase vehicular capacity can often
discourage alternative forms of transportation such as biking and walking. SB 743 directed the
OPR to develop an alternative metric(s) for analyzing transportation impacts in CEQA document.
The alternative shall promote the state’s goals of reducing greenhouse gas emissions and traffic-
related air pollution, promoting the development of multimodal transportation system, and
providing clean, efficient access to destinations. Under SB 743, it was anticipated that the focus
of transportation analysis will shift from vehicle delay to VMT within transit-priority areas (i.e.,
areas well served by transit).
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-7
Pursuant to SB 743, OPR released the draft revised CEQA Guidelines in November 2017,
recommending the use of VMT for analyzing transportation impacts for all projects. Additionally,
OPR released Updates to Technical Advisory on Evaluating Transportation Impacts in CEQA, to
provide guidance on VMT analysis. In this Technical Advisory, OPR provides its
recommendations to assist lead agencies in screening out projects from VMT analysis and
selecting a significance threshold that may be appropriate for their particular jurisdictions. While
OPR’s Technical Advisory is not binding on public agencies, CEQA allows lead agencies to
“consider thresholds of significance ... recommended by other public agencies, provided the
decision to adopt those thresholds is supported by substantial evidence” (CEQA Guidelines
Section 15064.7[c]).
In December 2018, the CEQA Guidelines were updated to add new Section 15064.3, Determining
the Significance of Transportation Impacts, that describes specific considerations for evaluating a
project’s transportation impacts using the VMT methodology.
CEQA Guidelines Section 15064.3(b) is divided into four subdivisions as follows:
1. Land Use Projects. Vehicle miles traveled exceeding an applicable threshold of
significance may indicate a significant impact. Generally, projects within one-half mile of
either an existing major transit stop or a stop along an existing high quality transit corridor
should be presumed to cause a less than significant transportation impact. Projects that
decrease vehicle miles traveled in the project area compared to existing conditions should
be presumed to have a less than significant transportation impact.
2. Transportation Projects. Transportation projects that reduce, or have no impact on,
vehicle miles traveled should be presumed to cause a less than significant transportation
impact. For roadway capacity projects, agencies have discretion to determine the
appropriate measure of transportation impact consistent with CEQA and other applicable
requirements. To the extent that such impacts have already been adequately addressed at a
programmatic level, such as in a regional transportation plan EIR, a lead agency may tier
from that analysis as provided in Section 15152.
3. Qualitative Analysis. If existing models or methods are not available to estimate the
vehicle miles traveled for the particular project being considered, a lead agency may
analyze the project’s vehicle miles traveled qualitatively. Such a qualitative analysis would
evaluate factors such as the availability of transit, proximity to other destinations, etc. For
many projects, a qualitative analysis of construction traffic may be appropriate.
4. Methodology. A lead agency has discretion to choose the most appropriate methodology
to evaluate a project’s vehicle miles traveled, including whether to express the change in
absolute terms, per capita, per household or in any other measure. A lead agency may use
models to estimate a project’s vehicle miles traveled and may revise those estimates to
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-8
reflect professional judgment based on substantial evidence. Any assumptions used to
estimate vehicle miles traveled and any revisions to model outputs should be documented
and explained in the environmental document prepared for the project.
The OPR’s regulatory text indicated that a public agency may immediately commence
implementation of the new transportation impact guidelines, and that the guidelines must be
implemented statewide by July 1, 2020. However, the OPR Technical Advisory allows local
agencies to retain their congestion-based LOS standards in general plans and for project planning
purposes. As mentioned in the County’s TAG, use of both metrics is required in a project’s
transportation analyses.
Therefore, this EIR relies on VMT as the basis for evaluating transportation impacts under CEQA. The
project’s LOS effects have been documented in the TIA prepared by Dudek for the proposed project.
California Department of Transportation
As the owner and operator of the State Highway System, the State of California Department of
Transportation (Caltrans) implements established state planning priorities in all functional plans,
programs, and activities. Caltrans has the responsibility to coordinate and consult with local
jurisdictions when proposed local land use planning and development may impact state highway
facilities. To comply with SB 743 implementation, the Caltrans Transportation Impact Study Guide
(May 2020), replaced the Guide for the Preparation of Traffic Impact Studies (Caltrans 2002). Per the
2020 Transportation Impact Study Guide, Caltrans’ primary review focus is VMT, replacing LOS as
the metric used in CEQA transportation analyses. Caltrans recommends use of OPR’s recommended
thresholds and guidance on methods of VMT assessment found in OPR’s Technical Advisory (OPR
2018). In addition to VMT, Caltrans has developed an Interim Land Development and
Intergovernmental Review (LDIGR) Safety Review Practitioners Guidance (July 2020) which may
request a targeted operational and safety analysis to address a specific geometric or operational issue
related to the State Highway System and connections with the State Highway System (Caltrans 2020).
To comply with this requirement, an assessment of off-ramp queuing at freeway ramps serving the
project has been included in the EIR.

Local
Contra Costa County General Plan
The purpose of the Contra Costa County General Plan is to express the broad goals and policies,
and specific implementation measures, which will guide decisions on future growth, development,
and the conservation of resources. The various elements or chapters of the plan are intended to
provide objectives, principles, and standards to decision-making bodies in the County, as well as
numerous other public agencies, that will be making decisions about the development of private
and public lands and the locations and extent of improvements such as transportation infrastructure
(CCTA TAG 2020). The Growth Management Element and the Transportation and Circulation
Element of the General Plan are described below.
i. Growth Management Element
In November 2004, Contra Costa voters renewed the original Measure C, Transportation
Improvement and Growth Management Program (GMP), a 0.5% sales tax to fund transportation
projects and programs, with a new ballot measure called Measure J. Measure J funds the County’s
GMP, which plans for cooperative growth management among jurisdictions within the County and
sets performance standards. Measure J requires local jurisdictions to be in compliance with the
GMP by adopting a Growth Management Element (GME); adopting a local and regional
Development Mitigation Program; participating in an on-going cooperative, multijurisdictional
planning process; addressing housing options; developing a 5-year capital improvement program;
adopting a Transportation Systems Management Ordinance or Resolution; and adopting a voter-
approved urban limit line.
A key principle for the GMP is that growth-inducing development within the County should be
required to pay for transportation facilities to meet the demands resulting from that growth. To
ensure this, the CCTA has created a regional Development Mitigation Program that requires
transportation fees to be paid by growth-inducing development to fund transportation
improvements. Furthermore, the Growth Management Implementation Guide of the GMP
establishes guidelines for review of General Plan amendments to ensure compliance with the
cooperative planning requirements of Measure J. The GMP also provides performance standards
to evaluate streets and public services associated with projects and General Plan amendments.
ii. Transportation and Circulation Element
The County’s Transportation and Circulation Element (“TCE”) establishes transportation goals,
policies, and specific implementation measures to assure that the transportation system of the County
will have adequate capacity to efficiently serve planned growth in Contra Costa County. The
intention of the TCE is to provide a plan and implementing measures for an integrated, multi-modal
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-10
transportation system that will safely and efficiently meet the transportation needs of all economic
and social segments of the County and provide for the transport of goods and services throughout
Contra Costa County (CCTA TAG 2020).
Relevant General Plan policies were considered in the establishment of thresholds of significance
(Section 3.13.3, Thresholds of Significance) for the proposed project. These policies are as follows:
Circulation Phasing and Coordination
5-2 Appropriately planned circulation system components shall be provided to accommodate
development compatible with policies identified in the Land Use Element.
5-3 Transportation facilities serving new urban development shall be linked to and compatible
with existing and planned roads, bicycle facilities, pedestrian facilities and pathways of
adjoining areas, and such facilities shall use presently available public and semi-public
rights of way where feasible.
5-4 Development shall be allowed only when transportation performance criteria are met and
necessary facilities and/or programs are in place or committed to be developed within a
specified period of time.
5-5 Right of way shall be preserved to meet requirements of the Circulation Element and to
serve future urban areas indicated in the Land Use Element.
Circulation Safety, Convenience and Efficiency
5-7 Through-traffic along arterials shall be improved by minimizing the number of new
intersecting streets and driveways; and, when feasible, by consolidating existing street and
driveway intersections.
5-8 Access points on arterials and collectors shall be minimized.
5-9 Existing circulation facilities shall be improved and maintained by eliminating structural
and geometric design deficiencies.
5-11 The use of freeways for community circulation shall be minimized by prioritizing
transit circulation, safe, direct non -motorized routes, and secondarily by additional
arterials and expressways.
5-13 The use of pedestrian and bicycle facilities shall be encouraged. Proper facilities shall be
designed to accommodate bikes, pedestrians, and transit.
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-11
5-14 Physical conflicts between pedestrians, bicyclists, and vehicular traffic, bicyclists, and
pedestrians shall be minimized.
5-16 Curbs and sidewalks shall be provided in appropriate areas.
5-17 Emergency response vehicles shall be accommodated in development project design.
5-20 New development (including redevelopment and rehabilitation projects) shall contribute
funds and/or institute programs to reduce parking demand and/or provide adequate parking.
5-21 New development shall contribute funds and/or institute programs to provide adequate
bicycle and pedestrian facilities where feasible.
Alternative Transportation/Circulation Systems
5-23 All efforts to develop alternative transportation systems to reduce peak period traffic
congestion shall be encouraged.
5-24 Use of alternative forms of transportation, such as transit, bike, and pedestrian modes, shall
be encouraged in order to provide basic accessibility to those without access to a personal
automobile and to help minimize automobile congestion and air pollution.
5-n Enforce County TDM (Transportation Demand Management) Ordinances consistent with
State law and encourage neighboring jurisdictions to adopt similar ordinances.
5-ak Provide safe and convenient pedestrian and bike ways in the vicinity of schools and other
public facilities and in commercial areas and provide convenient access to bus routes.
5-al Ensure that pedestrian connectivity is preserved or enhanced in new developments by
providing short, direct pedestrian connections between land uses and to building entrances.
5-as Provide sidewalks with a clear path wide enough to accommodate anticipated pedestrian
use and wheelchairs, baby strollers or similar devices. This area clear zone must be free of
street furniture, signposts, utility poles or any other obstruction.
5-at Traffic calming measures should be designed so they improve pedestrian and bicycle
movement in residential neighborhoods and commercial districts as well as strategic
corridors between them that help form the comprehensive bicycle network.
5-39 Reduce conflicts among motorists, pedestrians, and bicyclists.
5-aw Use curb extensions and pedestrian islands and other strategies to reduce pedestrian
crossing distances.
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-12
5-ax Use traffic control devices such as signs, signals, or lights to warn motorists that
pedestrians or bicyclists are in the roadway.
5-ay Provide buffers between roads and sidewalks utilizing planter strips or buffer zones that
provide streetscape improvements.
5-be Incorporate sidewalks, bike paths, bike lanes, crosswalks, pedestrian cut-throughs, or other
bicycle pedestrian improvements into new projects.
Capital Road Improvement and Preservation Program
The Capital Road Improvement & Preservation Program (“CRIPP”) is a programming document for
the funding of capital road improvement projects within Contra Costa County. It includes estimated
project costs, funding source information, and scheduling information for known potential projects
within the next seven fiscal years. It also includes revenue projections and a summary of estimated
project-related expenditures for each funding source (CCTA TAG 2020). County of Contra Costa
has identified several proposed (funded and unfunded) projects in the CRIPP for funding year (FY)
2020/21 and FY 2026/27 and some of those improvements have been referenced as potential
improvements in the proposed project’s TIA.
Complete Streets
On July 12, 2016, the Board of Supervisors (BOS) adopted Resolution No. 2016/374 approving the
Complete Streets Policy of Contra Costa County. This Policy expanded on a 2008 General Plan
amendment to support Complete Streets policies (CCTA TAG 2020). The County has established
Complete Streets Principles, Implementation measures, and Exceptions that may apply to plans or
projects from incorporating Complete Streets design elements.
Vision Zero Contra Costa County
The County is developing a Vision Zero Plan (Plan) to address severe and fatal collisions on County-
owned roadways. The Plan, to be adopted by the BOS this year or next, would include strategies
moving the County towards the goal of zero fatalities and major injury collisions on its roadway
network. The strategies outlined in the Plan include engineering, education, and/or enforcement
measures, which implement the primary goals such as meeting requirements for developing a Local
Road Safety Program, to eliminate fatal and serious injury collisions, prioritize infrastructure projects
that are in alignment with the Vision Zero Program, developing Vision Zero campaign, eliminate
high-risk behavior through Education and Enforcement, and fostering relationship among various
agencies related to the Vision Zero Program.

County Ordinance Code
The County Ordinance Code is the implementation tool of the General Plan and contains specific
provisions that address on and off-site circulation with the intent of preserving and improving the
quality and efficiency of the County transportation system. All land development proposals must
demonstrate compliance with these provisions.
i. Section 74-04.006 – Electric Vehicle (EV) Charging
In 2015, the Board of Supervisors adopted Ordinance No. 2015-22 amending the 2013 California
Green Building Standards Code to establish electric vehicle parking and charging station building
standards for the unincorporated County. County Code Section 74-4.006 - Amendments to
CGBSC – Electric Vehicle Charging standards apply to residential (single and multi-family) and
non-residential development.
ii. Chapter 82-16 – Off-Street Parking
The County’s Off-Street Parking Ordinance provides a unified set of standards for off-street vehicle
and bicycle parking to meet the needs of persons employed at, or making use of, each land use during
peak hours of parking needs. It is intended to encourage the use of features, design strategies,
materials, products, and best construction practices that preserve natural resources, conserve water
and energy, and maximize energy efficiency in the design of parking facilities and also intended to
balance the needs of pedestrians, vehicles, bicycles, and public transportation.
iii. Chapter 82-32 – Transportation Demand Management
The County’s Transportation Demand Management Ordinance intends to further the transportation
goals of the County General Plan, the Measure J Growth Management Program, Contra Costa
County's Congestion Management Program, and the Bay Area Clean Air Plan. Its purpose is to
implement the provisions of the General Plan to promote a more balanced transportation system that
takes advantage of all modes of transportation by:
• Incorporating pedestrian, bicycle, and transit access into improvements proposed in
development applications;
• Incorporating the overall intent and purpose of this chapter into the land use review and
planning process;
• Allowing requests for reductions in the off-street parking requirements for residential or
nonresidential projects that have a conceptual TDM Program;
• Providing information to residents on opportunities for walking, bicycling,
ridesharing and transit.
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-14
The County TDM Ordinance applies to:
• Residential projects containing thirteen or more dwelling units; and
• Any non-residential or mixed-use development proposal.
Contra Costa Transportation Authority
CCTA comprises of representation from all 19 cities, the unincorporated County, and the transit
agencies, and is responsible for ensuring the completion of a wide variety of projects that were
included in the original Measure C Expenditure Plan and the Measure J (approved by Contra Costa
voters in November 2004) Expenditure Plan. CCTA works cooperatively with local agencies on
funding and implementation of transportation projects.
i. Final 2017 Countywide Transportation Plan
On September 20, 2017, the CCTA adopted the Final 2017 Countywide Transportation Plan
Update, which provides goals, strategies, projects, and actions for achieving and maintaining a
balanced and functional transportation system within the County while considering land use
(CCTA 2017c). In addition, as part of the Countywide Transportation Plan, the regional
transportation planning committees updated their Action Plans for Routes of Regional Significance
(Action Plans). These Action Plans establish quantitative service objectives to assess the
conditions of the transportation system and impacts of land use decisions. The Action Plans help
local jurisdictions meet the requirement of the Measure J GMP that requires local jurisdictions to
participate in a cooperative, multijurisdictional planning process.
ii. CCTA Countywide Bicycle and Pedestrian Plan
The Countywide Bicycle and Pedestrian Plan (CBPP) builds on and expands the goals, policies and
strategies of the Countywide Transportation Plan. Both plans set goals for increasing walking and
bicycling and identify actions the Authority and its partners should take to achieve them. Within the
project vicinity, the County has goals for bicycle and pedestrian facilities that are contained in the
CBPP. The CBPP was originally adopted in 2003 and most recently updated in 2018. The CBPP
supports the Countywide Transportation Plan by adding goals, policies, and strategies specifically
focused on increasing walking and bicycling in the County (CCTA 2018). Facilities planned within
the CBPP that are located near the project site are shown in Figure 3.13-2 and Figure 3.13-3.
iii. CCTA Action Plans for Routes of Regional Significance
East County Action Plan for Routes of Regional Significance: In accordance with Measure J
requirements, the most recent update of the East County Action Plan for Routes of Regional
Significance (ECAP) was adopted in September 2017. The ECAP identifies routes of regional
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-15
significance within eastern Contra Costa County, establishes multimodal transportation service
objectives for these routes, and establishes actions for achieving those objectives (TRANSPLAN
2017). The purpose of the ECAP is to work cooperatively with local jurisdictions to establish
overarching goals; set integrated performance measures (i.e., multimodal transportation service
objectives) for designated “Routes of Regional Significance”; and outline a set of projects,
programs, measures, and actions that will support achievement of the multimodal transportation
service objectives. Furthermore, the ECAP creates a Development Mitigation Program to reduce
the impacts of projects on the transportation system.
Within the project vicinity, Routes of Regional Significance are Byron Highway south of SR-4,
Camino Diablo Road west of Vasco Road, SR-4, and Vasco Road. In addition, the planned TriLink
(see subheading below) is designated as a Route of Regional Significance.
iv. 2017 Contra Costa County Priority Development Area Strategy
The 2017 Contra Costa County PDA Strategy was adopted on May 17, 2017. The PDA Strategy
defines the criteria for selecting projects that support Plan Bay Area, the Regional Transportation
Plan developed by the Metropolitan Transportation Commission (CCTA 2017b). PDAs are
prioritized for development by local city or county governments. The PDA Strategy assists the
CCTA by providing guidelines for how the CCTA will support the development of PDAs in the
County. The PDA Strategy provides strategies to encourage and support development within PDAs
in the County. Along with this, the PDA Strategy identifies transportation and non-transportation
infrastructure needed to support development of designated PDAs, and coordinates investment in
projects that support and encourage development of PDAs for the maintenance and improvement
of the broader transportation system. Each update of the PDA Strategy documents progress made
since the previous update and includes transportation investments that are currently being targeted
to promote housing and job growth in areas with multimodal transportation options.
v. TriLink (SR-239) Feasibility Study Final Report
SR-239 was first identified in 1959 as a legislatively approved, but unconstructed, route in the
California state highway system. SR-239 would act as a potential multimodal link between SR-4
near Brentwood and I-205 west of Tracy in San Joaquin County. Although the route has not been
adopted by the California Transportation Commission, the County completed the TriLink
Feasibility Study Final Report on May 30, 2014, to evaluate the feasibility of the corridor (CCTA
2014). In August 2015, a Project Study Report was prepared to establish the range of potential
alternatives, and gain approval for formal studies and environmental documentation. SR-239 could
potentially improve access for those who live and work in the region and could support inter-
regional goods movement that would create jobs locally (Caltrans 2015b). The TriLink proposal
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-16
includes the Vasco–Byron Connector, which would connect Vasco Road to Byron Highway along
the Armstrong Road alignment north of Byron Airport.
Since the alignment and funding of the TriLink project has not been finalized, the transportation
analysis provided in the Project’s TIA (VMT and LOS) do not assume any of the roadway facilities
or improvements associated with the TriLink project.
vi. Travel Demand Model
Both the Measure C Growth Management Program (GMP) and the State congestion management
legislation require CCTA to develop and maintain a travel demand model. These models use
information on current and future population and employment, transit ridership, expected roadway
improvements, and observed travel behavior to forecast traffic on the regional transportation
system. The travel demand model is used to analyze the effects of new development and changes
in their general plans, analyze the effects on new transportation improvements and to analyze the
effects of its plans and programs, including the CTP and the Congestion Management Program
(CMP). Consistent with these requirements, the CCTA model was used in the proposed project’s
VMT and LOS analyses.
3.13.3 Thresholds of Significance
The significance criteria used to evaluate the project’s impacts to traffic and circulation are based
on Appendix G of the CEQA Guidelines. According to Appendix G of the CEQA Guidelines, a
significant impact related to traffic and circulation would occur if the project would:
1. Conflict with a program, plan, ordinance, or policy addressing the circulation system,
including transit, roadway, bicycle, and pedestrian facilities.
2. Conflict or be inconsistent with CEQA Guidelines Section 15064.3(b).
3. Substantially increase hazards due to a geometric design feature (e.g., sharp curves, or
dangerous intersections) or incompatible uses (e.g., farm equipment).
4. Result in inadequate emergency access.
Program, Plan, Ordinance and Policy
The programs, plans, ordinance, and policies listed in Section 3.13.1 were analyzed for their
applicability to the proposed project under Threshold 1.
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-17
Vehicle Miles Traveled
The Updated CEQA Guidelines state that “…generally, vehicle miles traveled (VMT) is the most
appropriate measure of transportation impacts…” and define VMT as “…the amount and distance
of automobile travel attributable to a project…”. It should be noted that “automobile” refers to on-
road passenger vehicles, specifically cars and light trucks. Heavy-duty truck VMT could be
included for modeling convenience and ease of calculation (for example, where models or data
provide combined auto and heavy truck VMT). Other relevant considerations may include the
effects of the project on transit and non-motorized travel.
Consistent with the OPR guidelines and CEQA Guidelines Section 15064.3 (b), the following
specific VMT metrics are recommended by the County to complete a VMT impact assessment:
• Residential Projects: VMT per resident for all home-based trips.
• Employment Projects: VMT per employee for only the home-based-work trip purpose
and would apply to office, industrial, and institutional projects.
• Regional Retail (>50,000 square feet): Total VMT per service population for trips taken
by both workers and visitors.
• Mixed-Use: Total VMT per service population.
• Other: Total VMT per service population for trips taken by both workers and visitors.
The project proposes a mix of office, warehousing and commercial land uses and therefore is
considered to be an employment project. Therefore, home -based work VMT per employee
metric was chosen for the project’s VMT analysis.
A proposed project should be considered to have a significant impact if the project VMT is greater than:
• Employment Projects (office, industrial and institutional projects): 15% below the Bay
Area average commute VMT per employee.
The project’s detailed VMT analysis was conducted using the Contra Costa Countywide Travel
Demand Model and is provided under Threshold 2. For significant VMT impacts found,
appropriate VMT reduction strategies such as the implementation of Transportation Demand
Management (TDM) measures, or other VMT-reducing measures, have been provided to mitigate
project impacts.
Hazardous Features (Project Access and Off-ramp Queuing)
The analysis evaluates whether the project would result in hazards due to design features by
determining whether the 95th percentile queuing at the Project access intersections and Caltrans
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-18
off-ramp intersections would exceed the storage pockets lengths. The following intersections were
analyzed for queuing impacts under Threshold 3:
• Byron Highway/Holey Road;
• Byron Highway/Byron Hot Springs Road;
• Mountain House Parkway/ I-205 westbound ramps; and
• Mountain House Parkway/I-205 eastbound ramps.
Emergency Access
The emergency access analysis evaluates whether the project would comply with County’s emergency
access and/or evacuation requirements including those imposed by the Fire Department.
Project Trip Generation
Trip generation estimates for the proposed project are based on daily and AM and PM peak hour
trip generation rates and fitted curve equations obtained from the Institute of Transportation
Engineers (ITE) Trip Generation Manual, 9th and 10th Editions (ITE 2012; 2017).
As the proposed project contains warehousing, industrial, general commercial, and office land
uses, this project is considered a multi-use development. The ITE rate for General Aviation Airport
(022) from the ITE Trip General Manual, 9th Edition was used for the proposed aviation land use
as rates provided in the 10th Edition. For the proposed general commercial land use, the ITE rate
for Shopping Center (820) is the most reflective of trip generation and pass-by for this use. Pass-
by trips were calculated using the average pass-by trip percentage presented within the ITE Trip
Generation Manual, 10th Edition, for the Shopping Center land use. Internal trip capture is
anticipated between the warehouse, industrial, general commercial, and office land uses.
Trip generation rates and the resulting trip generation estimates for the project are summarized in
Table 3.13-1.

As shown in Table 3.13-1, the proposed project would generate 8,617 daily trips, 486 AM peak hour
trips (348 inbound and 138 outbound), and 776 PM peak hour trips (300 inbound and 476 outbound).
When accounting for shopping center pass-by trip reductions, the proposed project would generate
8,617 net new daily trips, 413 AM net new peak hour trips (296 inbound and 117 outbound), and 660
PM net new peak hour trips (255 inbound and 405 outbound).
While trip generation is not used in the EIR for the purpose of determining impacts based on traffic
delay or congestion, it is helpful in assessing issues such as access and traffic hazards. Trip
generation also plays an important role in evaluating mobile emissions and noise impacts.

3.13.4 Impacts Analysis
Impact 3.13-1. The project would conflict with a program, plan, ordinance, or policy
addressing the circulation system, including transit, roadway, bicycle, and
pedestrian facilities.
The Contra Costa General Plan including GME and TCE, CRIPP, Complete Streets, Vison Zero
Contra Costa, County Ordinance Code and CCTA include plans, programs and policies that
address the circulation system in the County. If the proposed project does not implement a
particular program, plan, or policy, it would not necessarily result in a conflict as some of these
programs must be implemented by the County or other related agencies, over time and a broad
area. Rather, the proposed project would result in a conflict if it would preclude the County from
implementing adopted transportation-related programs, plans and policies.
The proposed project has the potential to conflict with the plans, programs, ordinances, and
policies described in the Section 3.13.1 that focus on policies or standards adopted to protect the
environment and support multimodal transportation options and reduce VMT. However, as shown
below the proposed project has taken the following measures to address any potential conflicts
with the circulation system:
• Consistent with the County’s General Plan which establishes policies and standards for safe
and efficient performance of the transportation system and the CCTA TAG 2020 guidelines
that requires land development projects be evaluated against operational and efficiency
standards of LOS and VMT, the proposed project has prepared a TIA report (Appendix H).
Based on the analysis provided in the TIA of the proposed project, mitigation measures for
CEQA impacts (as described in Section 3.13.4 and shown in Appendix H) and transportation
improvement measures for General Plan consistency (or Non CEQA) requirements (shown in
Appendix H) have been identified for the proposed project.
• The proposed project would comply with the County’s Ordinance Code to include required
EV charging stations and parking as well as the off-street parking standards. The details of
parking requirements would be addressed at the Design Review stage of the proposed
project. The proposed project would comply with the County’s TDM ordinance (described
in detail in Section 3.13.5).
• As discussed in Section 3.13.2, Transportation Setting, there is currently no transit service
to the project site or within the vicinity of the project site. The proposed project would
result in an increase in population and employment in the County, increasing the number
of people who may use public transit services. However, the project site is not directly
served by any transit routes. The closest existing transit stop is approximately 7 miles
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-21
northwest of the project site in the City of Brentwood. No planned public transit facilities
or services are planned for the project vicinity.
• There are no bicycle facilities that serve the project site. However, the Contra Costa CBPP
(CCTA 2018) has planned bicycle facilities for Byron Highway, Camino Diablo, Bixler
Road, Byer Road, and SR-4 (Figure 3.13-2). Per CBPP, as shown on Figure 3.13-3, Class
II bicycle lanes are proposed along Byron Hot Springs Road and Holey Road from project
site to Byron Highway. The local bicycle network would connect to the low-stress bikeway
(Class II) proposed along Byron Highway. The proposed project shall provide adequate
bike parking, change, and shower facilities on-site and improve accessibility for on-site
bicycle movement as well connections to immediate off-site locations by facilitating
connections with Class II bike lanes along Holey Road and Byron Hot Springs Road.
• In addition, there are no existing pedestrian facilities within the project vicinity. Due to the
lack of connectivity and significant development in the immediate project vicinity,
pedestrian activity is very light at present. However, with development of the proposed
project, pedestrian traffic is expected to increase due to the general commercial and office
components of the proposed project. Long-range planning for Byron Highway includes
possible pedestrian facilities in terms of sidewalks and a Class I multi-use path. Consistent
with County General Plan policies and Complete Street Policy, the proposed project is
expected to provide continuous sidewalks along the project frontage (where development
fronts a public street). Internally, pedestrian sidewalks, crosswalks, and accessible paths of
travel should be provided within the project site, as follows:
o Within the developed core to allow easy access to each building
o Between public street and the developed core
Where feasible, sidewalks would be configured to channel pedestrians to crosswalks.
The proposed project would comply with the County’s Complete Streets Policy, which requires
the needs of all users (including pedestrians, cyclists, motorists, and transit riders) to be met during
street design. The County’s Complete Streets Policy was adopted by Resolution No. 2016-374 by
the Board of Supervisors of Contra Costa County on July 12, 2016 (Contra Costa County 2016).
There is limited availability of alternative transportation facilities in the vicinity of the project site.
The proposed project would not disrupt or interfere with existing or planned bicycle or pedestrian
facilities, conflict with adopted pedestrian or bicycle system plans or policies, create a substantial
demand for mass transit services above existing or planned capacity, or interfere with existing or
planned transit facilities. However, the proposed project would not preclude the County or CCTA
from implementing any programs, plans and policies that would improve accessibility to transit,
bicycle, and pedestrian facilities in its vicinity.
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-22
Therefore, with the implementation of project-related actions described above, the proposed project
would not conflict with a program, plan, ordinance, or policy addressing the circulation system,
including transit, roadway, bicycle, and pedestrian facilities. Impacts would be less than significant.
Impact 3.13-2. The project would potentially conflict or be inconsistent with CEQA
Guidelines Section 15064.3(b). (Potentially Significant)
The following discusses the Proposed Project’s VMT impacts and its consistency with CEQA
Guidelines section 15064.3, subdivision (b).
Per the County’s guidelines, if a project meets any one of the following criteria it would not require a
detailed VMT analysis:
• Projects that:
o Generate or attract fewer than 110 daily vehicle trips1: or,
o Projects of 10,000 square feet or less of non-residential space or 20 residential units or
less, or otherwise generating less than 836 VMT per day.
As shown in project trip generation, the project would generate 8,617 daily trips and therefore
would not meet the small project screening criteria.
• Residential, retail, office projects, or mixed-use projects proposed within ½ mile of an
existing major transit stop2 or an existing stop along a high-quality transit corridor3.
The project is not located within ½ mile of an existing major transit stop or an existing stop along
a high-quality transit corridor per Public Resources Code Section 21155 and therefore, would not
meet the transit proximity screening.
• Residential projects (home-based VMT) at 15% or below the baseline County-wide home-
based average VMT per capita, or employment projects (employee VMT) at 15% or below
1 CEQA provides a categorical exemption for existing facilities, including additions to existing structures of up
to 10,000 square feet, so long as the project is in an area where public infrastructure is availabl e to allow for
maximum planned development and the project is not in an environmentally sensitive area. (CEQA Guidelines,
§ 15301, subd. (e)(2).). Typical project types for which trip generation increases relatively linearly with
building footprint (i.e., general office building, single tenant office building, office park, and business park)
generate or attract an additional 110 -124 trips per 10,000 square feet. Therefore, absent substantial evidence
otherwise, it is reasonable to conclude that the addition of 110 or fewer trips could be considered not to lead
to a significant impact.
2 Pub. Resources Code, § 21064.3 (“‘Major transit stop’ means a site containing an existing rail transit station, a ferry
terminal served by either a bus or rail transit service, or the intersection of two or more major bus routes with a
frequency of service interval of 15 minutes or less during the morning and afternoon peak commute periods.”).
3 Pub. Resources Code, § 21155 (“For purposes of this section, a high-quality transit corridor means a corridor with
fixed route bus service with service intervals no longer than 15 minutes during peak commute hours.”).
3.13 – TRANSPORTATION

the baseline Bay Area average commute VMT per employee in areas with low VMT that
incorporate similar VMT reducing features (i.e., density, mix of uses, transit accessibility)
As shown in the following VMT analysis, the project is not located within an area with low VMT
and the project’s employee VMT is above the baseline Bay Area average commute VMT per
employee. Therefore, the project does not meet the low VMT screening.
• Public facilities (e.g., emergency services, passive parks (low-intensity recreation, open
space), libraries, community centers, public utilities) and government buildings.
• The project proposes warehouse, office, and commercial uses which would complement
the existing airport use. Since it is not proposing public facilities and government buildings,
therefore, the project type screening would not apply.
The proposed project does not meet the screening criteria identified above; therefore, further
assessment of project’s VMT impact under base year conditions (year 2018) and cumulative
conditions (year 2040) is provided below using available significance thresholds and guidance
from the County.
Project Level Analysis
The 2010 CCTA model was utilized for VMT analysis of the proposed project. The CCTA is a
trip-based model that has been developed using Metropolitan Transportation Commission (MTC)
travel demand model. The 2010 Decennial update of the CCTA Model was a major update in
which the land use, network assumptions and model processes were updated to reflect the most
recent MTC travel demand model. The CCTA model uses TransCAD Version 5.0 (Build 1515)
software and generally follows the processes of the MTC trip-based model while providing
additional detail within Contra Costa. The model network is updated to reflect the MTC
transportation 2035 (T-2035) RTP network. The traffic analysis zones (TAZs) in the Countywide
Model began with MTC’s 1,099-zone model for the Bay Area that existed at the time the
Countywide Model was first developed. Later, approximately 1,700 TAZs were added in the
Contra Costa/Tri-Valley Study Area.
The current MTC model consists of 3,120 TAZs, of which 1,495 are located within Contra Costa.
Land use and demographic data are required for each TAZ. The demographic data provides the
basis for estimating trip generation. Both the demographic and transportation network data are
used in predicting trip distribution patterns and mode of travel. The land use data for the model is
updated every two to four years. The model land use and demographic inputs for traffic zones
within Contra Costa consist of variables such as number of households, residents, employment,
household income, high school, and college enrollment, etc. The highway and transit networks for
the Countywide Model are based on the existing and planned transportation system, including
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-24
freeways, arterials, major collectors, and selected minor collectors and include virtually all
signalized intersections in the study area. The transit network is based on MTC’s transit networks
with refinements based upon local review by the transit operators. For both highway and transit
networks, detailed networks within Contra Costa are combined with MTC networks outside the
county. The CCTA Model uses the auto ownership, trip generation, trip distribution and mode
choice modules within MTC’s BAYCAST-90 model. The model is used to generate highway and
transit outputs such as link volumes, intersection turn movements, volume to capacity ratios and
vehicle miles traveled as standard outputs.
Consistent with standard modeling practice, to identify VMT from the project, a traffic analysis
zone (TAZ) for the project was included in the CCTA model and select zone runs were conducted
for year 2018 and 2040. Since the primary purpose of SB 743 is to reduce home-based automobile
travel, only the employee VMT related to home-based work (HBW) passenger vehicle travel are
reported from the model for the project, the County, and the Bay Area. The findings of the project’s
VMT analysis for the base year (Year 2018) with and without the project are shown in Table 3.13-
2 below. Appendix A includes the VMT output from the CCTA model for year 2018 and 2040.

Source: Contra Costa Countywide Travel Demand Model
The HBW VMT per employee for the project is 21.2, for the County is 14.0 and for the Bay Area
is 14.9. As shown in Table 3.13-2, the HBW VMT per employee under with Project scenario,
decreases (from 22.7 to 21.2) nominally compared to the no project scenario. HBW VMT per
employee is an efficiency metric which is the ratio of total HBW employee VMT and number of
employees. Although the HBW VMT and number of employees in the airport zone increase under
with project scenario compared to the no project scenario, the ratio of total HBW employee VMT
and number of employees decreases nominally. A slight decrease in VMT per employee under
with project conditions compared to the without project conditions indicates that the project would
improve VMT efficiency in the region. However, it should be noted that the VMT significance of
threshold requires comparison of the project VMT with the regional average (i.e., Bay Area
Average), and not a comparison of with project and no project scenarios. The County threshold
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-25
for Employment Projects (office, industrial, and institutional projects) is that the project VMT
should be 15% below Bay Area average commute VMT per employee (i.e., home-based work
VMT per employee). The project’s HBW VMT per employee (21.2) is higher than the Bay Area
VMT per employee (14.9). To meet the threshold of 15% below Bay Area Average and have a
less than significant VMT impact, the HBW VMT per employee for the project should be
approximately 12.7, which would require a 40% reduction. Therefore, the proposed project would
have a potentially significant VMT impact. Transportation demand management strategies and
mitigation measures that can potentially achieve VMT reductions are provided in Section 3.13.5.
Cumulative Analysis
Per the County’s guidelines, cumulative impacts should be evaluated for consistency with the
County General Plan. If a project is consistent with the County General Plan (Envision 2040) and
the General Plan remains consistent with its VMT projections as originally analyzed, the project’s
cumulative impacts shall be less-than significant. However, if the project is inconsistent with the
adopted County General Plan, then the analysis should evaluate the project’s cumulative VMT
impacts and determine if the Countywide VMT increases or decreases with the proposed project
relative to the VMT generated by full General Plan buildout.
It should be noted that the County is currently updating its General Plan (Envision 2040) and as
mentioned in the project description, the project is proposing to update the ALUCP which would
allow non-residential development that are compatible with the land use plan for Byron Airport.
Therefore, the project would be increasing jobs and hence employment-related VMT compared to
the current General Plan and ALUCP. Table 3.13-3 provides the total employment VMT estimate
from the CCTA model for the Contra Costa County and the Byron Airport zone for the year 2040.
It should be noted that for VMT analysis, the cumulative analysis is based on comparing the total
VMT with and without project for the Byron Airport Zone with the County, whereas the project
analysis is based on comparing the efficiency metric i.e., the HBW VMT per employee of the
project zone with the regional average (i.e., Bay Area Average).

Since the Countywide VMT would increase with the proposed project relative to the total VMT
generated by the County under year 2040 conditions, the project’s cumulative impacts would be
considered significant.
Impact 3.13-3. The project would substantially increase hazards due to a geometric design
feature (e.g., sharp curves, or dangerous intersections) or incompatible
uses (e.g., farm equipment). (Potentially Significant)
The following discussion describes the potential for increased hazards as a result of geometric
design features of the project, and/or as a result of the addition of project traffic to adjacent
roadway facilities.
Project Site Access
Regional access to Byron Airport and the project site is provided via SR -4 to the north, I-205 to
the south, and Byron Highway to the east. Direct access to the project site is provided via Holey
Road and Byron Hot Springs Road from Byron Highway. Both Holey Road and Byron Hot Springs
Road are two-lane collector roads, with minor street stop control at their intersections with Byron
Highway. Additionally, Armstrong Road provides a connection to Falcon Way and the western
portion of the project site from Byron Hot Springs Road.
The levels of service at the two project access roads from Byron Highway (intersections #1 and #2) is
provided in the following chapters and summarized in Table 3.13-4 below for all analysis scenarios.

Both intersections were analyzed as two-way stop controlled (TWSC) intersections. As such, the turning
movement with the highest delay is reported. As shown in Table 3.13-4, both project access study
intersections are forecast to operate at LOS F during the PM peak hour at Intersection 1, and during both
peak hours at intersection 2 in both study scenarios. The western leg of the intersection is stop controlled
at both intersections, and the eastbound left-turning movement is the primary cause for the deficient LOS
during all scenarios. All other movements at the intersection operate at LOS A or B.
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-27
A queuing analysis was prepared at the intersections of Holey Road and Byron Hot Springs Road
with Byron Highway to determine the potential for queuing hazards both on the minor streets and
along Byron Highway. Queuing summaries for Existing and Future Year 2040 conditions are
provided in Tables 3.13-5 and 3.13-6, respectively.
As shown in Tables 3.13-5 and 3.13-6 the calculated 95th percentile (design) queues for the Existing
and Future Year plus Project conditions, respectively, exceed available vehicle storage capacities at
both intersections. As no turning pockets or two-way-left-turn (TWLTL) facilities are provided along
Byron Highway at the project access study intersections, storage capacity does not exist and therefore
has been assumed to be zero. For stop-controlled side-street movements, storage capacity is measured
from the study intersection to the nearest paved intersecting roadway for the purpose of this analysis.
Queuing on Byron Highway, specifically at the northbound left turning movements onto Byron
Hot Springs Road and Holey Road, could lead to increased delays and degradation of Byron
Highway traffic operations. Although the project would directly not add northbound left-turning
movements to the intersection of Byron Highway/Byron Hot Springs Road, increased project
traffic at other movements (i.e., eastbound left-turning movement from Byron Hot Springs Road)
would impact queueing of the northbound travel lane. Both intersections operate at deficient levels
of service, therefore improvement measures are identified for both intersections in the project’s TIA.
Implementation of these improvement measures would reduce queuing at both intersections with
improvements to the delay and therefore impact would be less than significant.
The project has the potential to increase the volume of truck traffic on the roadway network to
serve warehousing and light industrial development. Although regional roadways, such as Byron
Highway and SR-4, already safely handle significant volumes of truck traffic, the rural roads
providing access to Byron Airport may not support the increase in truck traffic. For example,
Byron Hot Springs Road south of Armstrong Road narrows to 20 feet wide with 3-foot-wide gravel
shoulders (providing 10-foot-wide travel lanes for two-way traffic). Armstrong Road has adequate
width (16-foot-wide travel lanes), although the turn radius at Armstrong Road and Byron Hot
Springs may require large trucks to travel off of the paved street section (onto a soft shoulder).
Holey Road, which would provide an important southerly access to the airport-related
development area, narrows to 21 feet of paved road width with narrow shoulders. Although
existing traffic volumes can be handled on these roads, they may be inadequate for increased
volumes of project-related traffic, including increased truck traffic. Therefore, this impact would
be potentially significant. Therefore, the project proponent would construct the street
improvements along Armstrong Road, Byron Hot Springs Road, and Holey Road described in MM-
TRAF-9 to reduce access impacts related to heavy truck traffic.

Freeway Ramp Queuing
Due to the potential for the proposed project to add traffic to Caltrans facilities within the study
area, the following Caltrans freeway off-ramps were analyzed for queuing impacts:
• Mountain House Parkway/ I-205
westbound ramps
• Mountain House Parkway/I-205
eastbound ramps
As shown in Table 3.13-7, no peak 95th percentile queues are expected to exceed the storage
pocket lengths in the Existing plus Project conditions. However, as shown in Table 3.13 -8,
peak 95th percentile queues are expected to exceed storage pocket lengths in the Future Year
2040 plus Project , AM peak hour conditions at the Mountain House Parkway/I -205 westbound
ramp intersection and for the following turning movements:
• Westbound left-thru lane (WBLT): This is a storage lane that extends from the intersection to
approximately 700 feet from the stop bar. It is expected that forecast queues would extend past
the available pocket length and contribute to queuing in the adjacent westbound right turn lane
(WBR1 and WBR2), which serve as the primary off-ramp lanes from the freeway mainline.
• Westbound right-turn lane 1 (WBR1): This is a primary off-ramp lane that extends from
the intersection to approximately 1,515 feet to the gore line at the I-205 mainline. It is
expected that forecast queues would extend past the available storage length and contribute
to existing queueing into the mainline.
• Westbound right-turn lane 2 (WBR2): This is a primary off-ramp lane that extends from
the intersection to approximately 1,515 feet to the gore line at the I-205 mainline and serves
as an exit-only lane from the 11th Street on-ramp, approximately 1-mile upstream. It is
expected that forecast queues would extend past the available storage length and contribute
to existing queueing into the mainline within this exit-only lane.
When comparing the Future Year 2040 scenario with the addition of the proposed project,
queueing is forecast to increase for all movements during the AM peak hour at the Mountain House
Parkway/I-205 westbound ramps; vehicle traffic would continue to spill into the mainline lanes in
Future Year 2040 no Project and plus Project conditions.
No current funded or planned improvements are identified at the I-205 westbound ramps with
Mountain House Parkway. The TriLink (SR-239) Feasibility Study Final Report identifies
potential alignments for the proposed SR-239 corridor between SR-4 to the north and I-580 and/or
I-205 to the south, which would reduce traffic volumes on I-580, Vasco Road, and Byron Highway
(CCTA 2014). As such, shifts in regional traffic patterns could also reduce congestion and queuing
at the Mountain House Parkway/I-205 westbound ramps. However, as the SR-239 Feasibility
Study does not identify specific improvements, nor are specific improvements planned or funded
in the area, hazards related to queuing at this off-ramp would remain significant and unavoidable.

Impact 3.13-4. The project would not result in inadequate emergency access. (Less
Than Significant)
The project would not interfere with an adopted emergency response or evacuation plan. Internal
airport roadways would be designed in accordance with Uniform Fire Code standards, and prior
to the issuance of building permits, adequate emergency access would be ensured through the plan
check process and fire review. Implementation of the project would increase the number of access
points to Byron Airport (for example, from Holey Road). Construction activities may result in
short-term lane closures. Any lane closures due to construction activity would be coordinated with
emergency service providers to maintain access. Access to Byron Airport and surrounding
properties would be maintained throughout construction. Therefore, the proposed project would
have a less-than-significant impact associated with inadequate emergency access.
3.13.5 Mitigation Measures
As shown in Section 3.13.4, the project would have a significant VMT impact. The following section
provides a summary of measures that can be implemented to mitigate the project’s VMT impact. In
addition, mitigation is identified to address the width of Armstrong Road, Byron Hot Springs Road,
and Holey Road.
Transportation Demand Management (TDM) measures can be implemented as project design
features and/or mitigation measures for reducing VMT. The California Air Pollution Control
Officers Association (CAPCOA) Quantifying Greenhouse Gas Mitigation Measures, 2010 report
has identified actions and changes to project features that reduce VMT. Additionally, the County’s
Transportation Demand Management Ordinance Guide published in December 2009 by the
Department of Conservation & Development has outlined effective ways to reduce vehicle trips
(hence VMT) added by new development projects.
Table 3.13-9 describes strategies from the County’s TDM Ordinance Guide and CAPCOA as
sample options that would be most effective in areas like the community of Byron and are
appropriate for the project to avoid or reduce the significant impact. VMT reductions for each of
the strategy (using the applicable range of effectiveness) that can be applied to the project have
been estimated per CAPCOA’s mitigation measure calculation provided in Fact Sheets of the
document. Only the strategies that would be applicable to suburban locations such as the project’s
location were used. Further, high-level assumptions regarding project’s site design were made
since the project’s site plan was not available at the time of preparation of the TIS. A conservative
estimate of employee participation was applied to the VMT reduction calculation.

Project Site Design Features (including Pedestrian
Facilities)
A comprehensive design that features pedestrian
amenities, covered bus stops and adequate
accessibility, benches, passenger loading zones, etc.
To encourage walking, safe, and convenient pedestrian
access and movement need to ensure as part of the
project site design, the proposed project would include
the following design elements:
1. Minimize walking distances along the internal
street/path network to provide convenient
connections between the different buildings,
services, etc.
2. Design gathering areas where enhanced
landscaping, adequate lighting, signage, and street
furniture are provided so that walking can be
naturally encouraged with the provision of such
design elements.
3. Establish traffic calming devices where feasible on
the internal street system.
4. Other design considerations that are safety related
include the provision of adequate sight triangles at
project driveways and internal intersections, as
well as preventing parking encroachment within
pedestrian sidewalks and walkways.
5. Give a priority to establishing and maintaining
pedestrian facilities such as sidewalks, marked
crosswalks and stop bars, in-pavement lighted
crossing, bulb-outs, and other traffic calming
devices, street, and pedestrian lighting, sheltered
seating areas, and landscaping.
LUT-9/3.1.9 Improve Design of Development – Project
design elements that enhance walkability and connectivity
can be measured in terms of sidewalk coverage, building
setbacks, street widths, pedestrian crossings, presence of
street trees, and a host of other physical variables that
differentiate pedestrian-oriented environments from auto-
oriented environments.
SDT-1/3.2.1 Provide Pedestrian Network Improvements -
Providing a pedestrian access network to link areas of the
Project site encourages people to walk instead of drive. This
mode shift results in people driving less and thus a reduction
in VMT. A project should provide a pedestrian access
network that internally links all uses and connects to all
existing or planned external streets and pedestrian facilities
contiguous with the project site. A project should minimize
barriers to pedestrian access and interconnectivity. Physical
barriers such as walls, landscaping, and slopes that impede
pedestrian circulation will be eliminated.
SDT-2/3.2.2 Provide Traffic Calming Measures -
Providing traffic calming measures encourages people to
walk or bike instead of using a vehicle. This mode shift
results in a decrease in VMT. Project design should include
pedestrian/bicycle safety and traffic calming measures in
excess of jurisdiction requirements. Roadways should be
designed to reduce motor vehicle speeds and encourage
pedestrian and bicycle trips with traffic calming features.
Traffic calming features may include: marked crosswalks,
count-down signal timers, curb extensions, speed tables,
raised crosswalks, raised intersections, median islands, tight
corner radii, roundabouts or mini-circles, on-street parking,
planter strips with street trees, chicanes/chokers, and
others.
3.0% - 21.3% VMT reduction
% VMT Reduction = Intersections * B
Where
Intersections = Percentage increase in intersections
versus a typical ITE suburban development;
B = Elasticity of VMT with respect to % of
intersections (0.12 from CAPCOA).
Since the project’s site plan was not available at
time of the preparation of this document, it was
conservatively assumed that a 3% VMT reduction
would be achieved using this measure.
0 – 2% VMT reduction
1% VMT reduction is allowed for pedestrian
accommodations within project site in urban and
sub-urban context.
0.25 – 1% VMT reduction
The reduction is based on % of streets within project
with traffic calming improvements and % of
intersections within project with traffic calming
improvements. Since the project’s site plan was not
available at time of the preparation of this
document, it was conservatively assumed 50% of
project’s on-site streets and 50% of project’s on-site
intersections would be designed with these
considerations. This would allow 0.5% VMT
reduction.

Bicycling Facilities:
The design measures listed below can be established
by the project and approved as part of the development
application review process:
1. Provide secure short- and long-term bicycle
parking (i.e., bicycle racks and lockers,
respectively) at prime locations of the development
sites.
2. Provide showers, change facilities, and clothes
lockers at convenient locations within business
buildings in order to encourage cycling for longer
distances.
3. Ensure safe and convenient access and
movements of cyclists within development sites.
SDT-5/3.2.5 Incorporate Bike Lane Street Design (on-
site) - A project should incorporate bicycle lanes, routes,
and shared-use paths into street systems, new subdivisions,
and large developments. These on-street bike
accommodations can provide a continuous network of
routes, facilitated with markings and signage. These
improvements can help reduce peak-hour vehicle trips by
making commuting by bike easier and more convenient for
more people.
SDT-6/ 3.2.6 Provide Bike Parking in Non-Residential
Projects- A non-residential project should provide short-
term and long-term bicycle parking facilities to meet peak
season maximum demand. Bike Parking in Non-Residential
Projects has minimal impacts as a standalone strategy and
should be grouped with the Improve Design of Development
strategy to encourage bicycling by providing strengthened
street network characteristics and bicycle facilities.
SDT-9/3.2.9 Dedicate Land for Bike Trails - Larger
projects may be required to provide for, contribute to, or
dedicate land for the provision of off-site bicycle trails linking
the project to designated bicycle commuting routes in
accordance with an adopted citywide or countywide bikeway
plan. The benefits of Land Dedication for Bike Trails have
not been quantified and should be grouped with the Improve
Design of Development strategy to strengthen street
network characteristics and improve connectivity to off-site
bicycle networks.

Transit Facilities:
1. Provide safe and direct site access to the public
streets where transit services are provided.
2. Provide necessary transit facilities in the vicinity of
project site (such as bus shelter, bus turnout,
concrete pad, seating, lighting, etc.), in order to
support transit use.
3. Establish an on-site information kiosk where
information on transit routes, schedules, and fares
can be provided.
4. Intersection geometry and road structure should
be capable of supporting the length and weight of
buses, including internal project circulation roads if
bus or shuttle service is anticipated to enter the
project site.
5. Communicate with the local transit agency (Tri
Delta Transit) to seek changes/addition to bus
route to support transit ridership for the project.
6. Provide shuttle service to main transit station
during the commute periods.
TST-2/3.5.2 Implement Transit Access Improvements
This project should improve access to transit facilities
through sidewalk/ crosswalk safety enhancements and bus
shelter improvements. The benefits of Transit Access
Improvements alone have not been quantified and need to
be grouped with Transit Network Expansion (TST-3) and
Transit Service Frequency and Speed (TST-4).
TST-3/3.5.3 Expand Transit Network –A project should
expand the local transit network by adding or modifying
existing transit service to enhance the service near the
project site. This will encourage the use of transit and
therefore reduce VMT.
Grouped Strategy (TST-3 and TST-4)
0– 8.2% VMT reduction
% VMT Reduction = Coverage * B * Mode * D
Where
Coverage = % increase in transit network coverage;
B = elasticity of transit ridership with respect to
service coverage (value from CAPCOA);
Mode = existing transit mode share;
D = adjustments from transit ridership increase to
VMT (0.67, from Appendix D of CAPCOA)
Since the project is located in a sub-urban area with
no existing transit service, a low range % VMT
reduction (10% expansion, sub-urban) was
assumed. Therefore, 0.1% VMT reduction would
be achieved using this measure.
Commute Trip Reduction Strategies:
1. Rideshare/Carshare Initiatives
a. Designate a number of on-site parking spaces at
prime locations (i.e., close to buildings access,
well lit, etc.) for carpools and vanpools privately
operated by tenants. Short-term parking spaces
or passenger loading areas are also needed for
taxi and outside shuttle services. Establishing
carpool/vanpool initiatives can reduce the overall
demand for on-site parking.
TRT-3/3.4.2 Provide Ride-sharing Programs - Increasing
the vehicle occupancy by ride sharing will result in fewer
cars driving the same trip, and thus a decrease in VMT.
Ride-sharing program and a permanent transportation
management association membership and funding
requirement. Funding may be provided by Community
Facilities, District, or County Service Area, or other non-
revocable funding mechanism. Ride-sharing programs can
be promoted through a multi-faceted approach such as:
Designating a certain percentage of parking spaces for ride
sharing vehicles
0– 15% commute VMT reduction
% VMT Reduction = Commute *Employee
Where
Commute = % reduction in commute VMT (from
CAPCOA);
Employee = % employees eligible;
For the project, commute = 5% (low density suburb
annual reduction); 50% of the employees were
assumed to be eligible for participation in the

2. Establish on-site car rental or carshare services so
that tenants do not need to rely on personal cars
for work-related purposes.
3. Employer Sponsored Vanpool/Shuttle
Designating adequate passenger loading and unloading and
waiting areas for ride-sharing vehicles
Providing a web site or message board for coordinating
rides
TRT-9/3.4.9 Implement Car-Sharing Program- A car-
sharing project allows people to have on-demand access to
a shared fleet of vehicles on an as-needed basis. User costs
are typically determined through mileage or hourly rates,
with deposits and/or annual membership fees. The car-
sharing program could be created through a local
partnership or through one of many existing car-share
companies. Employer-based car-sharing programs provide
a means for business/day trips for alternative mode
commuters and provide a guaranteed ride home option.
TRT-11/3.4.11 Provide Employer-Sponsored
Vanpool/Shuttle- Implementing an employer-sponsored
vanpool or shuttle will usually service employees’ commute
to work while a shuttle will service nearby transit stations
and surrounding commercial centers. Employer-sponsored
vanpool programs entail an employer purchasing or leasing
vans for employee use, and often subsidizing the cost of at
least program administration, if not more. The driver usually
receives personal use of the van, often for a mileage fee.

4. Flexible Work Schedules and Telecommuting
a. Flexible Work Schedule programs established by
employers govern the time period in which
employees travel to and from work. Such
programs influence employees’ propensity to
consider using transit, carpooling, and other
alternatives to driving alone to work.
b. Telecommuting exists in several forms, such as
working at home, working at a satellite center
with shorter commuting distance, and working at
neighboring work centers that can be leased to
several employees and where office equipment
is provided.
5. TDM Coordinator and/or Marketing Strategies.
a. A TDM Coordinator is typically responsible for
developing, marketing strategies, implementing
and evaluating the TDM programs. The TDM
Coordinator can be a designated on-site staff
person (half- to full-time) with specific TDM
responsibilities and authority. The Coordinator’s
responsibilities can also be contracted out with a
commute company. Since educational and
Scheduling is within the employer’s purview, and rider
charges are normally set on the basis of vehicle and
operating cost.
TRT-6/ 3.4.6 Encourage Telecommuting and Alternative
Work Schedules- Encouraging telecommuting and
alternative work schedules reduces the number of commute
trips and therefore VMT traveled by employees. Alternative
work schedules could take the form of staggered starting
times, flexible schedules, or compressed work weeks.
TRT-7/ 3.4.8 Implement Commute Trip (CTR) Reduction
Marketing/ Launch Targeted Behavioral Interventions
Implementing marketing strategies to reduce commute trips
and information sharing are important components to
successful commute trip reduction strategies. Implementing
commute trip reduction strategies without a complementary
marketing strategy will result in lower VMT reductions.
Marketing strategies may include:
C = adjustments from vanpool mode share to
commute VMT;
For the project, A =20% for larger employer; B =
50%; C = 0.676 (See CAPCOA Appendix C)
% VMT Reduction = 20%*50%*0.67= 6.7%

promotional activities are needed to launch TDM
program, the TDM coordinator plays a key role in
coordinating with transportation service
providers (such as 511 Contra Costa), hosting
various event and providing pertinent information
to all tenets and employees regarding the
facilities, programs, and services available at the
project site.
6. Transit Incentive
a. Employees can be provided with incentives to
take transit to commute to work by providing
subsidized transit passes/fares, participating in
the regional transportation programs.
• New employee orientation of trip reduction and
alternative mode options
• Event promotions
• Publications
TRT-4/3.4.4 Implement Subsidized or Discounted Transit
Program - Providing subsidized/discounted daily or monthly
public transit passes may also provide free transfers
between all shuttles and transit to participants. These
passes can be partially or wholly subsidized by the employer
or development.

Parking Supply and Demand Management
Strategies - Establishing fees for on-site parking
combined with a strong TDM program can help shift
driver’s behavior to the use of alternative modes of
transportation and higher occupancy vehicles.
However, there are no existing transit or alternative
transportation facilities near the project that employees
can use to access the project. Therefore, only selective
parking management strategies that have been
included previously such as preferential parking for
ridesharing/carpooling programs and design of
development to limit on-site conflict locations between
vehicular parking and pedestrian/cyclists movements
would be applicable to the project.

3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-41
Based on Table 3.13-9, following mitigation measures and VMT reduction percentage has been
summarized for the proposed project.
MM-TRAF-1 Project Site Design: The project shall provide site design features that facilitate
pedestrian amenities and promote accessibility for on-site pedestrian movement and connectivity
to various buildings or project components.. As shown Table 3.13-10, this measure would result
in a range of reduction in VMT.
MM-TRAF-2 Bicycling Facilities: The project shall provide adequate bike parking, change, and
shower facilities on-site and improve accessibility for on-site bicycle movement as well as
connections to immediate proposed off-site bike lanes along Byron Hot Springs Road and Holey
Road. As shown in Table 3.13-10, this measure would result in a 0.63% reduction in VMT. Low
stress bikeway proposed along Byron Highway can be made accessible to bicyclists from the
project if bike routes can be planned along Holey Road and Byron Hot Springs Road.
MM-TRAF-3 Access to Transit and Expansion of Transit Network: The project shall provide
access to transit and expand transit network. The project should work with Tri Delta Transit to add
transit service in the project vicinity and provide connections with the cities of Antioch,
Brentwood, Pittsburg and Oakley and other unincorporated areas. As shown Table 3.13-10, this
measure was assumed to result in a conservative 0.1% reduction in VMT since there are no known
transit service improvement or expansion projects near the project site. However, once transit
coverage is increased, this VMT reduction could increase, however it would not reduce the
Project’s VMT to a less than significant level.
MM-TRAF-4 Ridesharing and Car-Sharing Programs for Employees: The project shall
provide/promote/subsidize ride-sharing programs to the employees by utilizing approaches such
as designating a certain percentage of parking spaces for ride sharing vehicles, designating
adequate passenger loading/unloading and waiting areas for ride-sharing vehicles, and providing
a website or message boards for coordinating rides. Increasing the vehicle occupancy by utilizing
ride sharing will result in fewer cars driving the same trip, thereby decreasing the VMT. As shown
in Table 3.13-10, providing ridesharing and car-sharing programs to approximately 50% of the
employees would result in a 2.5% and 0.4% reduction in VMT.
MM-TRAF-5 Employer-Sponsored Vanpool/Shuttle: The project shall provide an employer-
sponsored vanpool and shuttle for use by employees for commutes to work, and bus/transit station.
The vanpool and shuttle will be available to all employees; however, the calculations
conservatively assume the program would be offered to/utilized by 50 percent of employees. As
shown in Table 3.13-10, providing employer-sponsored vanpool/shuttle to approximately 50% of
the employees, would result in a 6.7% reduction in VMT.
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-42
MM-TRAF-6 Encourage Telecommuting and Alternative Work Schedules for Employees:
According to CAPCOA, encouraging telecommuting and alternative work schedules would reduce
the number of commute trips, thereby reducing the project’s VMT. Staggered start times, flexible
schedules, or compressed work weeks are examples of alternative work schedules. Because retail
and industrial/warehouse operations may require most of the employees to be on-site 24-hours per
day, alternative work schedules may be feasible for a majority of the employees. The project shall
implement a 4-day/40-hour work schedule for approximately 25% of the employees. As shown in
Table 3.13-10, with 25% employee participation in an alternate work schedule consisting of a 4-
day/40- hour work week, a VMT reduction of 3.75% would result.
MM-TRA-7 Implement Commute Trip Reduction Marketing: The project shall implement
marketing strategies to reduce commute trips. The marketing strategies would include new
employee orientation of trip reduction and alternative mode options, event promotions and
publications. Although the marketing would target all employees, a conservative assumption of
marketing to only 50 percent of the employees was utilized in the calculation. As shown in Table
3.13-10, implementing/promoting commute trip reduction marketing to approximately 50% of the
employees, would result in a 2.0% reduction in VMT.
MM-TRAF-8 Implement Subsidized or Discounted Transit Program for Employees: The
project shall provide subsidized or discounted daily or monthly public transit passes to the
employees. Although subsidized or discounted transit program would be available to all
employees, the VMT reduction calculation conservatively assumes that the program would be
available to and utilized by a maximum of 50% of employees. As shown in Table 3.13-10,
implementing subsidized or discounted transit program to approximately 50% of th e
employees, would result in a 1.0% reduction in VMT.

1. The calculated reductions do not sum to a total since the effect of individual strategy reductions are multiplicative not additive. Total % VMT
Reduction = 1-(1-A)*(1-B)*(1-C) where A, B, C equals reductions for individual strategies.
The proposed project’s VMT with mitigation is summarized in Table 3.13-11. The VMT
reductions associated with the above mitigation measures are applied incrementally, resulting in a
lower net reduction in comparison to the sum of the numbers. The 19.7 % reduction in VMT is
applied to the Project’s HBW VMT per employee and results in 17.0 HBW VMT per employee,
which is still above the 15% below the Bay Area average threshold of 12.7 HBW VMT per
employee. Even with the implementation of the mitigation measures, the proposed project’s
significant impact cannot be fully mitigated. Therefore, the proposed project would result in a
significant and unavoidable impact.
Per preliminary estimates based on building square footage proposed for each use, the buildout of
the project comprises of approximately 800 employees. Therefore, the County may require that as
a condition of approval, the individual project tenants prepare TDM or CTR Program that establish
performance standards (i.e., trip reduction requirements) which can be m onitored on a regular
basis. Or the County may require the TDM program to be developed comprehensively for the
entire project with flexibility to adjust to changing conditions (i.e. lower or higher VMT generating
tenants), innovation and technological advancements.
The project applicant/tenants should also work with 511 Contra Costa and use their county-wide
program to reduce commuter trips by providing information, resources, and tools that promote
mobility options such as biking, using transit, walk, micro mobility, carpool, van pool, working
from home and guaranteed ride home.

related to the project site, as follows:
• Widen Byron Hot Springs Road to provide two 12-foot travel lanes and 5
to 8-foot-wide shoulders (based on design ADT approved by Public Works
Department per County Standard Plan document and to include bike lanes
and sidewalk) from Byron Highway to Holey Road.
• Widen Holey Road to provide two 12-foot travel lanes and 5 to 8-foot-wide
shoulders (based on design ADT approved by Public Works Department

from the Airport property line to Byron Highway.
• Ensure an adequate paved turn-radius at the intersection of Byron Hot Springs
Road and Armstrong Road to facilitate appropriate truck movement.
• Ensure an adequate paved turn-radius at the intersection of Byron Hot
Springs Road and Holey Road to facilitate appropriate truck movement.
3.13.6 Level of Significance After Mitigation
As shown 3.13.5 Mitigation Measures, even with the implementation of measures MM-TRAF-1 through
MM-TRAF-8, the project’s VMT impacts (Threshold 2) would remain significant and unavoidable.
Implementation of MM-TRAF-9 would reduce access impacts related to heavy truck traffic to a
less-than-significant level. However, as discussed in 3.13.4, under analysis of Threshold 3, no
feasible improvements have been identified at the Mountain House Parkway/ I-205 westbound
ramps that would have a queuing-related impact, therefore hazards related to queuing would
remain significant and unavoidable.
3.13 – TRANSPORTATION
Byron Airport Development Program EIR 9269
February 2022 3.13-45
3.13.7 Indirect Impacts
The proposed project is located within a high VMT TAZ and as shown in the analysis of
Threshold 2, the HBW VMT per employee of the propo sed project is significantly above the
regional average. It should be noted that the project area is served primarily by vehicular modes
and does not have transit, pedestrian, and bike accessibility under existing or buildout conditions.
Additionally, even though level of service and delay is not considered a CEQA impact , the
improvements identified to improve traffic operations in the project’s TIA which would require
construction of additional on -site and off-site roadway improvements, can have indirect e ffects
such as induced travel to the environment. Implementation of the on-site improvements such as
internal roadways would be required and this EIR assumes full buildout of the aviation and
airport -related development areas. Off -site improvements identi fied in the project’s TIA would
require funding from additional sources such as CRIPP and County’s Development Mitigation
Program. At the time of this writing, some of the improvement measures identified in the TIA
are not funded. However, the project’s fair-share contribution towards these improvement
measures has been identified in the TIA.
Improving road infrastructure (i.e., adding lanes, signalization at intersections) may induce travel
demand, resulting in an increase in VMT. However, until final impr ovements are identified and
added to the CCTA model, quantifying the effects of induced travel would lack accuracy.
Qualitatively, the construction of additional roadway capacity may increase the effects of Impact
3.13-2. The improvements have been identif ied based on regional traffic projections and are
required to maintain an acceptable level of traffic operations per County’s LOS standards .
3.13.8 Cumulative Analysis
Cumulative impacts, including future traffic volumes, are incorporated into Impact Section 3.13.4,
Impacts Analysis for each of the threshold. The impact statements therefore reflect both direct and
cumulative conditions.

3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-1
3.14 UTILITIES
This section describes the existing utilities setting of the Byron Airport Development Program
(project) site, identifies associated regulatory requirements, evaluates potential impacts, and
identifies mitigation measures related to implementation of the proposed project.
3.14.1 Existing Conditions
3.14.1.1 Water Supply
The project site is not currently served by a public water system (PWS). The water system on site
consists of a domestic well with a 4,000-gallon holding tank, booster pump, and chlorinator. The
water supply is for domestic purposes and not drinking water. Water is currently supplied to serve
the site’s fire protection system, on-site bathrooms, and aircraft wash rack. Bottled water is used
to provide drinking water at the project site.
The existing fire suppression system consists of 11,000 feet of pipeline and 20 hydrants connected
to a 100-horsepower pump located in a pump house on the northeast side of Runway 12-30. The
pump has a design capacity of 3,000 gallons per minute and would draw from a 750,000-gallon
on-site pond dedicated for fire protection, if necessary. Water for this pond is supplied by the
Byron Bethany Irrigation District (BBID) through a pump located above the underground portion
of Canal 45 (LFA 2005; Mead & Hunt 2013).
The site’s water system is permitted as a transient non-community water system (Water System
No. CA0706110), which means that the water system regularly serves at least 25 non-residential
individuals (transient) during 60 or more days per year (CA Drinking Water Watch 2016).
However, this classification is no longer accurate, because the water supplied is non-potable and
thus does not serve individuals (and thus not a public water system). Drinking water available on
site is purchased from commercial suppliers, and the water system is used for non-potable purposes
(e.g., aircraft wash rack).
The site’s non-potable water system consists of a 200-foot-deep groundwater well connected to a
4,000-gallon holding tank. The yield of the well is estimated to be between 40 and 60 gallons per
hour, or up to 1 gallon per minute. The water is distributed through a 2-inch-diameter pipeline
extending from the groundwater well to the northwest, parallel to the taxiway and past the hangars
to the Byron Jet Center. The main water uses at the site are seven sinks, five toilets, three urinals,
and the aircraft wash rack. Based on California Waterworks Standards, the existing domestic water
system is estimated to be at 48% capacity, and can provide an additional 2,080 gallons of water over
a 4-hour period of peak hourly demand, or approximately 560 gallons per hour (Mead & Hunt 2013).
3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-2
3.14.1.2 Wastewater
Although there are several municipalities and service districts that provide sewer service in Contra
Costa County (County), rural areas typically use and maintain privately owned septic tanks and
leachfields where no public sewer service is available.
Byron Airport’s sewer service is currently provided by approximately 2,500 linear feet of sanitary
sewer collection lines and an underground septic tank with a lift station to a leach field that is
located southwest of the main aircraft camp (Mead & Hunt 2013). The lift station contains two 2-
horsepower pumps that each have a 46-gallons-per-minute maximum capacity. The leach field has
a current capacity of 1,720 gallons per day (gpd). Current septic system demand is low due to low
usage at Byron Airport, which include seven sinks, five toilets, three urinals, and the aircraft wash
rack (Mead & Hunt 2013). There are no restrooms located within the Byron Jet Center, but
restrooms are “stubbed” for future connection to water and sewer service. The peak daily sewage
flow was estimated by Mead & Hunt (2013) as being 672 gallons, or approximately 39% of system
capacity, which is 1,720 gpd. A more recent inspection indicates that the system is operating
properly, but the septic tank is only 2,000 gallons, and the system is operating at close to capacity
(Williams 2019).
3.14.1.3 Stormwater Drainage
The County Flood Control and Water Conservation District is responsible for the construction and
maintenance of regional drainage and flood control facilities. Typically, the County Public Works
Department maintains public drainage facilities in the unincorporated County, such as roadway
culverts and ditches, and storm drains within a public right-of-way.
Stormwater drainage at the project site primarily runs through natural drainage swales, ditches,
and watercourses. Please refer to Section 3.8, Hydrology and Water Quality, for more detail
regarding the on-site drainage.
The primary receiving water for the existing and proposed development footprint of the proposed
project is an approximately 15-acre detention basin located southeast of Runway 12-30 and east
of Runway 5-23 (Google Earth 2018; LFA 2005). This basin, along with a system of drainage
ditches and stormwater pipes designed for a 10-year storm, collects runoff from the majority of
the developed portions of the project site (Mead & Hunt 2013). The existing aviation uses
(administration building, aircraft and vehicle parking, hangar spaces, maintenance warehouses,
pump house, wash rack, and other ancillary structures) are graded to drain northeast toward
Runway 12-30 and its taxiway, which, through pipes and ditches, directs storm flows to the
southeast and eventually to the detention basin (LFA 2005). Runway 5-23 and its taxiway direct
storm flows to the east–northeast, also to the detention basin (LFA 2005). Under normal
circumstances, storm flow that is collected by the detention basin is either lost to evaporation,
3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-3
and/or percolates into the underlying groundwater table. During extreme storm events (i.e., greater
than a 10-year storm), when the detention basin reaches its holding capacity, it is designed to
overflow into a ditch that flows north under Holey Road and then northeast to the lower-most reach
of Brushy Creek near Highway 14, approximately 0.5 miles upstream of its confluence with Indian
Slough (Mead & Hunt 2013).
3.14.1.4 Dry Utilities
Information on energy and telecommunications is based on the Byron Airport Infrastructure Study
(Mead & Hunt 2013). Energy is further discussed in Section 3.15, Energy Consumption.
Electricity
Electric service is provided by Pacific Gas & Electric Company (PG&E). Electrical power is
supplied to the project site by PG&E by a 12-kilovolt line from Holey Road. PG&E’s services are
provided in accordance with California Public Utilities Commission rules and regulations.
Natural Gas
Byron Airport is not serviced by natural gas. However, a PG&E high-pressure transmission line is
located on the project site (crossing under Runway 5-23).
Telecommunications
Communications service to Byron Airport is currently provided by AT&T via underground lines.
There is an existing AT&T fiber-optic line on the Byron Highway corridor that could be extended
to Byron Airport.
3.14.1.5 Solid Waste
Solid waste collection services in the County are generally provided by private haulers through
either a contract or franchise. The County Health Services Department, Environmental Health
Division, certified by the California Department of Resources Recycling and Recovery
(CalRecycle), currently monitors and maintains residential solid waste collection and recycling
services in the County. The Airports Division contracts with Mount Diablo Resource Recovery
(MDRR) to handle solid waste generated by the County operations at the airport. Individual tenants
are responsible for making their own arrangements with a solid waste collection service.
Throughout the County, there are seven solid waste and recycling facilities and transfer centers:
West Contra Costa Sanitary Landfill, West County Integrated Resource Recovery Facility –
Central Processing Facility, Contra Costa Transfer and Recovery Station (CCTRS), ACME
Landfill, Keller Canyon Landfill, Brentwood Transfer Station, and Pittsburg Recycling Center and
3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-4
Transfer Station (Contra Costa County 2005a). Keller Canyon Landfill is a large-volume landfill,
which serves the County, as well as the surrounding Bay Area counties. Keller Canyon Landfill is
28 miles from the project site. CalRecycle currently estimates the capacity will last another 49
years (CalReycle 2019a). Potrero Hills Landfill is located approximately 50 miles from the project
site and could also possibly be used to dispose of wastes generated by the proposed project.
Altamont Landfill, in Alameda County, is 15 miles away from the project site. The Altamont
Landfill has sufficient capacity through 2045 (Waste Management 2019). Altamont Landfill and
CCTRS accept construction debris in addition to commercial waste. Three additional construction
and demolition waste management facilities have capacity to serve the project. These facilities
include Byron Crushing & Grinding Services and Woodmill Recycling Company, both of which
are located in Byron, and the MDRR Transfer Station facility in Pittsburg. MDRR provides
commercial waste collection services for Byron that will be utilized by the project.
3.14.2 Relevant Plans, Policies, and Ordinances
This section includes applicable federal, state, and local laws, regulatory guidance, and general
plan goals and policies that govern public utilities in the County.
3.14.2.1 Water
Federal Regulations
The Safe Drinking Water Act (SDWA) is the main federal law that regulates the quality of potable
water for the public. The SDWA authorizes the U.S. Environmental Protection Agency (EPA) to
establish national health-based standards for drinking water quality. These standards may apply to
naturally occurring and human-caused constituents in drinking water. The national standards are
established using scientific methods to evaluate health risks and consider available technology and
costs to achieve the standards. The National Primary Drinking Water Regulations establish
maximum contaminant levels (MCLs) or mandated methods for water treatment to remove
contaminants, and requirements for regular water quality testing to make sure standards are achieved.
In addition to setting these standards, the EPA provides guidance, assistance, and public information
about drinking water; collects drinking water data; and oversees state drinking water programs.
States can apply to the EPA for authority to implement the SDWA within their jurisdiction by
showing that they will adopt standards at least as stringent as the national standards and adequately
enforce these standards. California has been granted this authority, and the California Department of
Public Health establishes and enforces statewide drinking water standards.
3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-5
State Regulations
California Safe Drinking Water Act
The California Department of Public Health administers the state’s SDWA through the Drinking
Water Program. This program implements the regulatory authority of the Department of Public
Health over PWSs in the state. PWS operators are required to regularly monitor their drinking
water sources and supplies for microbiological, chemical, and radiological contaminants to
demonstrate that the water meets the regulatory requirements regarding primary MCLs listed in
Title 22 of the California Code of Regulations (CCR). MCLs have been established for ±80
inorganic and organic contaminants and six radiological contaminants. Monitoring is also required
for a number of other contaminants and characteristics that deal with the aesthetic properties of
drinking water, such as taste, odor, and appearance. These are known as secondary MCLs.
The Drinking Water Program is implemented by the Department of Public Health in cooperation
with the EPA, the State Water Resources Control Board (SWRCB), Regional Water Quality
Control Boards (RWQCBs), and other state and local agencies, including county health
departments, planning departments, and boards of supervisors.
San Joaquin Basin Plan
The Water Quality Control Plan (Basin Plan) for the project region was adopted by the Central
Valley RWQCB in 1998 and amended in 2015 (Central Valley RWQCB 2015). The Basin Plan
establishes water quality objectives for the Sacramento River Basin to protect the beneficial uses
of these waters, which include providing drinking water supplies.
Beneficial uses of the surface waters include municipal and domestic supply; agricultural supply;
industrial service, process, and power supply; contact and non-contact recreation; freshwater,
migration, spawning, and wildlife habitat; and navigation. Beneficial uses for groundwater include
municipal and domestic supply, agricultural supply, and industrial service and process supply
(Central Valley RWQCB 2015).
To protect the beneficial uses, the Basin Plan establishes objectives for surface water and
groundwater. Surface water objectives cover the following characteristics and qualities: bacteria,
bio-stimulatory substances, chemical constituents, color, dissolved oxygen, pesticides,
radioactivity, salinity, sediment, settleable material, suspended material, tastes and odors,
temperature, toxicity, and turbidity. Groundwater quality objectives cover the topics of bacteria,
chemical constituents, radioactivity, tastes and odors, and toxicity (Central Valley RWQCB 2015).

Drinking Water Quality Regulations and Standards
The principal state regulatory agency involved in drinking water quality and potable reuse in
California is the SWRCB Division of Drinking Water (DDW). The SWRCB receives the majority
of its statutory authority related to public health and potable water from the California SDWA, as
defined in the California Health and Safety Code and in Titles 17 and 22 of the CCR. In addition,
the SWRCB DDW has the primary enforcement authority (primacy) to enforce the federal SDWA,
and is responsible for the regulatory oversight of approximately 8,000 PWSs1 throughout the state.
The SWRCB also administers and enforces regulations pertaining to protection of water qua lity
and beneficial uses of water (including surface water and groundwater) under the Porter -Cologne
Water Quality Control Act, aspects of the federal Clean Water Act, and other statutes.
The California SDWA prescribes enforceable primary standards for five major categories of
drinking water contaminants: microorganisms, disinfectants and disinfection byproducts,
inorganic chemicals, organic chemicals, and radionuclides. Primary drinking water standards
established by the SWRCB under the California SDWA are equivalent or more stringent than those
set by the EPA under the aforementioned federal SDWA. The SWRCB DDW has adopted new or
more stringent drinking water standards for at least 16 inorganic and 33 organic contaminants, two
groups of disinfection byproducts, two individual disinfection byproducts, and two treatment
technique requirements. Domestic Water Quality and Monitoring Regulations (22 CCR Section
64400 et seq.) include MCLs for chemicals, monitoring requirements, compliance determination
procedures, and requirements for public notification in case of failure. Monitoring requirements
were also established in 2001 for nine unregulated organic and inorganic chemical contaminants,
which allowed collection of information on their presence in drinking water supplies. In addition,
secondary MCLs have been established for non-health concerns based on aesthetic issues, such as
taste, odor, or color in the water. The SWRCB and EPA have established secondary MCLs for at
least 15 contaminants.
The Surface Water Treatment Rule (22 CCR Section 64650 et seq.) is a set of regulations intended
to control the pathogenic microorganisms found in surface sources by setting treatment
requirements in lieu of MCLs. The regulations establish source sanitary survey, multibarrier
treatment, treatment design, operation, reliability, monitoring, reporting, and failure notification
requirements. The regulation requires that the source be an approved surface water (i.e., a surface
water or groundwater under the direct influence of surface water) that has received permit approval
from the SWRCB in accordance with Sections 116525 through 116550 of the California Health
and Safety Code.
1 Public water systems are systems that either have 15 or more service connections or serve at least 25 individuals
daily at least 60 days out of the year.
3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-7
Public Water System Permitting
PWS permits are issued to each producer or purveyor of drinking water serving a specified
minimum number of connections as required by the California Health and Safety Code. The permit
covers each source of water used by the system. These permits and their accompanying
engineering reports identify the source site, construction, and contaminant threats, and establish
the treatment, operational, and monitoring requirements for each source. Almost all permits
include special provisions established specifically for the individual water system, setting forth
operating requirements that, if not met, could result in a formal enforcement action. Permits do not
have expiration dates, but whenever a water system adds a new water source, adds or changes
treatment, has a change in ownership, or makes changes that are not in compliance with SWRCB
DDW drinking water regulations, then an amendment to the water permit is required. The proposed
project will likely need to expand or modify the current water system, and newly provide for
potable drinking water service. As such, the project proponent will be required to undergo the
permitting process with SWRCB DDW to obtain a PWS permit prior to leasing new facilities.
A Consumer Confidence Report is required annually for each PWS (22 CCR 64481). Each report
must contain information on the source of the water delivered, including the following:
• The type of water delivered by the water system (e.g., surface water, groundwater, and the
commonly used name [if any] and location of the body of water).
• If a source water assessment has been complet ed, notification that the assessment is
available, how to obtain it, the date it was completed or last updated, and a brief summary
of the system's vulnerability to potential sources of contamination.
The Consumer Confidence Report is intended to clearly communicate to the public the source of the
water, threats to the source, and any water quality problems. Should Byron Airport develop a water
system to provide drinking water, the project proponent may be required to obtain a PWS permit and
publicize its annual drinking water quality reports (Consumer Confidence Report) online.

Water Well and Small Water System Permitting
Contra Costa Environmental Health works with 125 small water systems to make sure that the
cleanest, safest, and most reliable drinking water possible is delivered to approximately 12,000
users (Contra Costa County 2018a). A small water system has less than 200 service connections
(Contra Costa County 2018a). Those operating small water systems in the County must possess a
valid water supply permit from Contra Costa Environmental Health, provide an emergency
notification plan in case of a health emergency, and perform required monitoring and reporting of
water quality as specified by state regulations (County Municipal Code 414-4.401–417, Small
Water Systems).
The Contra Costa Environmental Health Land Use Program protects the groundwater of the County
by reviewing the plans for well designs, issuing permits for the construction and destruction of wells
and soil borings, and conducting inspections during drilling to make sure wells and soil borings will
be installed or destroyed in a way that does not contaminate the County’s groundwater (Contra Costa
County 2018b). Wells and soil borings that require permits from Contra Costa Environmental Health
include water wells, dewatering wells, monitoring wells, cathodic protection wells, geothermal
wells, piezometers, inclinometers, soil vapor probes, CPTs, and soil borings (including geotechnical
borings) (Contra Costa County 2018b). Any work on wells (e.g., installation, modification,
destruction) must be performed by California-licensed well contractor (C-57 license) approved by

California Integrated Solid Waste Management Act – Assembly Bill 939
Assembly Bill 939, passed in 1989, mandated a focus on the conservation of natural resources.
Cities and counties were required to create comprehensive source reduction, recycling, and
composting programs (Public Resources Code Section 40000 et seq.). The goal of these programs
is to reduce the amount of waste sent to landfills by 50%. The focus of this bill was a major change,
shifting the emphasis from landfill disposal toward waste reduction, recycling, and composting
whenever possible. This approach aims to conserve natural resources, save energy, decrease
pollution, and provide new jobs in the waste industry.
Assembly Bill 939 established the following priorities for waste management:
• Waste reduction
• Recycling and composting
• Controlled combustion of waste to generate electricity
• Landfilling
Mandatory Commercial Recycling— AB 341
AB 341 was adopted as part of the AB 32 Scoping Plan by the Air Resources Board pursuant to
the California Global Warming Solutions Act on January 17, 2012. The legislation declares as a
policy goal of the state that not less than 75% of solid waste generated be source reduced, recycled,
or composted by the year 2020. The regulation requires businesses that generate 4 cubic yards or
more of commercial solid waste per week and multifamily residential dwellings of five units or
more to arrange for recycling services. The measure focuses on increasing commercial waste
diversion to reduce greenhouse gas emissions.
Mandatory Commercial Organics Recycling—AB 1826
AB 1826 was enacted in October 2014 in order to divert commercial organic waste from landfills.
The measure requires businesses and multifamily residential dwellings of five or more units to
recycle organic waste on and after April 1, 2016 depending on how much solid waste they generate
per week. The law includes phasing of requirements over time to ensure that the minimum
threshold of organic waste generation by businesses decreases gradually.
Mandatory Organics Recycling—SB 1383
Senate Bill 1383 was passed in September 2016, which established methane emissions reduction
targets to reduce emissions from short-lived climate pollutants. SB 1383 aims to achieve a 50

reduction by 2025. Cities and Counties are required to implement comprehensive organic waste
diversion programs that focus on recovering edible food for human consumption and diverting
organic material from the landfill. The goal is to reduce greenhouse gas emissions, increase organic
waste diversion from landfills, feed people, and maximize use of existing resources. SB 1383

3.14.3 Thresholds of Significance
The significance criteria used to evaluate the project’s impacts to utilities and service systems are
based on Appendix G of the California Environmental Quality Act (CEQA) Guidelines. A
significant impact related to utilities and service systems would occur if a project would:
1. Require or result in the relocation or construction of new or expanded water, wastewater
treatment or storm drainage, electric power, natural gas, or telecommunications facilities,
the construction or relocation of which could cause significant environmental effects.
2. Not have sufficient water supplies available to serve the project and reasonably foreseeable
future development during normal, dry, and multiple dry years.
3. 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.
4. 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.
5. Not comply with federal, State, and local management and reduction statutes and
regulations related to solid waste.
3.14.4 Impacts Analysis
Impact 3.14-1. The project would result in the construction of new or expanded water,
wastewater treatment, storm drainage, electric power, natural gas, or
telecommunications facilities, the construction or relocation of which could
cause significant environmental effects. (Potentially Significant)
Water
The project site is not connected to public water services; instead, the project site relies on existing
on-site water wells and a 4,000-gallon on-site water tank for its domestic, non-potable water.
Bottled water is used for drinking water. Development of the proposed project would exceed the
capacity of the existing system, resulting in a potentially significant impact.
3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-16
Development of the proposed project would require additional water sources. The discussion of
water supply is found in Impact 3.14-2, below. This analysis is based on the Water Supply
Assessment prepared for the project (included as Appendix I of this EIR). The water supply for
development of the proposed project would be from one of three potentially feasible sources:
• On-site development and treatment of additional groundwater
• Importation of treated water from Discovery Bay
• Importation and on-site treatment of additional water from BBID
The project could use groundwater, but additional well development would be required, and on-
site treatment would be needed for potable water. Potential impacts to groundwater are discussed
in Section 3.8 of this EIR.
Importation of treated water from Discovery Bay would require the construction of a water main
and would likely require a booster pump and water storage tank on the airport property (Mead &
Hunt 2013).
Importation of BBID water would require construction of a transmission line. A BBID canal
carrying untreated water, Canal 45, crosses the project site along the northeastern edge of Runway
12-30. However, it is not clear that a direct connection to Canal 45 would be allowed, in which
case a transmission line would be constructed to Byron Airport (Mead & Hunt 2013). In addition,
BBID water is untreated, and a treatment facility would need to be constructed on the project site.
Mitigation Measure (MM) UTIL-1 describes the process to identify and develop the preferred
water source prior to project implementation. MM-UTIL-1 requires that the applicant secure
appropriate agreements and entitlements with off-site providers prior to allowing development
with new human occupancies to occur.
Construction of on-site water facilities would have impacts similar to the development of the
proposed aviation and non-aviation land uses described in this EIR. Off-site impacts would be
similar to the proposed project, including impacts to air quality, biological resources, cultural
resources, geology, greenhouse gas emissions, hazardous materials, hydrology, noise, and
transportation. The indirect impacts and applicable mitigation are discussed in Section 3.14.6,
Level of Significance After Mitigation.
Wastewater
The increase in wastewater production associated with the proposed project would exceed the
capacity of the existing septic system and leach field. The Byron Airport Infrastructure Study
estimated that an additional 42,000 square feet could be developed at Byron Airport and be served
3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-17
by existing infrastructure (Mead & Hunt 2013). At this time, however, the septic system is near
capacity and would not support additional uses as currently configured (Williams 2019).
The Byron Airport Infrastructure Study considered two potential wastewater generation rates (Mead
& Hunt 2013). The Infrastructure Study compared two generation rates for bulk warehousing and
industrial development: the Central Contra Costa Sanitary District’s Collection System Master Plan
rate of 1,000 gpd per gross acre, and the City of Oakland rate of 25 gpd per 1,000 square feet of
building square footage. The Infrastructure Study used the Oakland rate of 25 gpd per 1,000 square
feet, resulting in an estimated 96,000 gpd build-out demand. The development assumptions in the
Infrastructure Study are greater than for the proposed project (146.9 acres and 3,840,000 square feet
of building space, compared to 70 acres and 941,000 square feet of building space for the proposed
project). Applying the Oakland rate to the proposed project would result in an estimated wastewater
flow of 23,525 gpd. However, the Town of Discovery Bay, which contains the nearest wastewater
treatment plant, uses a wastewater generation rate of 2,000 gpd per acre of industrial development
and 1,600 gpd per acre of commercial development (Discovery Bay Community Services District
2012). Using these flow rates, wastewater flow would be 89,920 gpd for non-aviation uses.2
Development of the proposed project would, therefore, exceed septic system capacity, resulting in a
potentially significant impact to water quality.
MM-UTIL-2 would require implementation of a wastewater system, per the recommendations of
the Byron Airport Infrastructure Study (Mead & Hunt 2013), which studied several options for
expansion of the on-site sewer system. The options include requiring each new use or development
to provide for its own wastewater disposal, in effect distributing wastewater treatment to smaller
leach fields throughout the site, or development of centralized treatment though use of an on-site
package wastewater treatment plant and establishment of collection pipelines. For an on-site
treatment plant, effluent disposal may be accomplished through landscape irrigation if the effluent
is treated to a level to meet Title 22 CCR standards. A third option is connection to an existing
sewer system: either the Discovery Bay Community Services District or the Byron Sanitary
District. Connection to Discovery Bay would involve off-site construction of a force main and
likely modifications to the existing sewage lift station (or a new lift station). Connection to Byron
Sanitary District would likely require an expansion of Byron Sanitary District’s wastewater
treatment facility. Connection to either Discovery Bay or Byron Sanitary District may also conflict
with the County’s Urban Limit Line policy.
A potential scenario would be the expansion of the septic system to accommodate aviation
development (which tends to have very low flows), and construction of a package wastewater
treatment plant for the non-aviation uses. The location of the runway would likely make sewer
connections between the aviation and non-aviation areas infeasible. Whichever option for on-site
2 35.6 acres of warehousing and light industrial development at 2,000 gpd per acre, plus 11.7 acres of commercial
development at 1,600 gpd per acre would yield 89,920 gpd .
3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-18
wastewater treatment is selected, it would be required to comply with applicable local, RWQCB,
and SWRCB permitting requirements meant to protect the beneficial uses of receiving waters, and
to comply with Basin Plan water quality objectives. Depending on the type, location, and
destination of the wastewater discharge, future facilities may be required to conform with the
County Sewage Collection and Disposal Ordinance (Chapter 420-6), the Water Quality Control
Policy for Siting, Design, Operation and Maintenance of On-Site Wastewater Treatment Systems
(OWTS Policy, Resolution No. 2012-0032), and/or waste discharge requirements.
Given the constraints on the existing wastewater disposal system and the engineering/permitting
constraints of various options, the development of non-aviation uses would likely require
construction of a package sewage treatment plant requiring a NPDES Permit and/or Waste
Discharge Requirements from the Central Valley RWQCB. Wastewater system permitting would
include effluent limitations, discharge specifications, and receiving water limitations designed
specifically for the location and type of discharge, and waste discharge requirements would include
monitoring and reporting program requirements meant to verify that the objectives of the waste
discharge requirement permit are being met. Furthermore, because on-site wastewater treatment
would occur within the development footprint of the project, its potentially significant
environmental effects with regard to other issue areas have been addressed in this EIR. For these
reasons, the proposed project would have a less-than-significant impact on water quality.
Construction of on-site facilities would occur in one of the areas identified for development, and
would have impacts similar to the development of the proposed aviation and non-aviation land
uses, including impacts to air quality, biological resources, cultural resources, geology, greenhouse
gas emissions, hazardous materials, hydrology, noise, and transportation (see Section 3.14.6). Any
proposed facility must comply with federal and state water quality requirements, as permitted
through the Central Valley RWQCB, in addition to approvals by the County Public Works Director
and Health Officer. Connection to existing off-site facilities would require construction of a sewer
line. The impacts of off-site mitigation are discussed in Section 3.14.6.
Stormwater
The project would not require or result in the construction or expansion of off-site stormwater
drainage facilities. However, construction of new stormwater drainage facilities would be required
within the development footprint of the proposed project. Because all such facilities would be
located on site, they are included in the environmental analysis for each issue area addressed by
this EIR. Impacts related to the expansion of the existing on-site drainage system would be less
than significant.
Please refer to Section 3.8 of this EIR for additional discussion of drainage and water quality. MM-
HYD-1, through implementation of a Master/Conceptual Stormwater Control Plan, is designed to
3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-19
avoid or substantially minimize water quality impacts and would require individual facilities to
develop project-specific Stormwater Control Plans.
Dry Utilities
As discussed in Section 3.14.1, energy and communications infrastructure is available on or near
Byron Airport. Electrical power is supplied to the project site by PG&E by a 12-kilovolt line from
Holey Road. This connection is adequate to serve proposed development at the project site (Mead &
Hunt 2013). Individual service connections would be constructed as part of the overall development
of the proposed project. Natural gas is not currently used at Byron Airport, but is available. AT&T
provides telecommunications service. A fiber-optic connection is available. Construction of service
connections for dry utilities is assumed in the overall development of the proposed project and is
considered within this impact analysis. The impact would be less than significant.
Conclusion
The proposed project’s requirements would exceed existing water and wastewater infrastructure,
which would have a potentially significant impact without mitigation. The construction impacts
associated with expansion of water, wastewater and stormwater infrastructure are addressed
elsewhere in this EIR and do not represent new significant impacts. Adequate energy and
telecommunications capacity is available to the project site.
Impact 3.14-2. The project would not have sufficient water supplies available to serve the
project from existing entitlements and resources. (Potentially Significant)
The expansion of Byron Airport would result in a substantial increase in on-site water use. The
estimated construction water demand for the proposed project is 31 acre-feet spread out over a 10-
year build-out period, equivalent to an average of 3.1 acre-feet per year (Appendix I). Operations
and maintenance activities for the proposed project would require a water demand that would
increase to approximately 36 acre-feet per year by the end of the 10-year build-out period. Because
a definitive source of water for the proposed project has not yet been identified, three sources are
examined as potential supplies: on-site groundwater, imported water from the Town of Discovery
Bay (Discovery Bay), and additional imported water from the BBID. On-site groundwater was
determined to be the supply with the least potential, as there is evidence of low yields and poor
groundwater quality from existing wells. However, extraction of on-site groundwater may
potentially be used to provide redundancy and backup for another supply. The Discovery Bay
water supply is exclusively from groundwater, and the analysis indicates that Discovery Bay could
reliably support the proposed project currently and through the 20-year planning period. The BBID
service area includes part of the project site, and the BBID supplies to the area are mainly surface
water diverted from State Water Project facilities. The BBID supply would likely support the
proposed project’s water demand through the planning period (Appendix I).

Byron Airport Development Program EIR 9269
February 2022 3.14-20
Currently, the well serving the airport property is insufficient to serve additional project
development. This impact is potentially significant. According to the Water Supply Assessment
completed for the proposed project, at the programmatic level of analysis, sufficient water supplies
are available to serve its water demand under normal and dry conditions, including existing and
planned land uses, over the 20-year projection period (Appendix I). This would be accomplished
through the use of one or more of the aforementioned options. However, as development under
the proposed project proceeds, each of the potential supplies considered would require additional
feasibility analysis to determine the actual potential for project implementation, and would require
appropriate agreements (e.g., will-serve letter) from the off-site suppliers before any development
requiring potable water could be permitted. This process is incorporated into MM-UTIL-1.
Impact 3.14-3. The project would exceed the current wastewater treatment capacity to
serve the project’s projected demand in addition to the provider’s existing
commitments. (Potentially Significant)
The project site is not currently served by a wastewater treatment provider. The airport is currently
served by a septic system which does not have capacity for the proposed project. This impact is
potentially significant. As discussed for Impact 3.14-1, Byron Airport may seek to connect with
the Discovery Bay Community Services District or the Byron Sanitary District or could require
developers to incorporate on-site wastewater disposal systems into their development plans.
Implementation of MM-UTIL-2 would ensure that, should an off-site wastewater treatment
provider be used, the feasibility of using it would be evaluated, including a determination of
adequate capacity for current and future users. Therefore, the impact would be less than
significant.
Impact 3.14-4. The project would not generate solid waste in excess of State or local
standards, or in excess of the capacity of local infrastructure, or otherwise
impair the attainment of solid waste reduction goals. (Less than Significant)

Landfill has an estimated remaining lifespan of approximately 49 years, and the Altamont Landfill
has capacity through 2045. Keller Canyon Landfill has a maximum permitted daily throughput of
3,500 tons, while Altamont has 11,150 tons. Assuming a total waste generation of 7.2 tons per day
at project buildout (see Table 3.14-1), this would represent 0.2% and 0.06% of the maximum
throughput, respectively. Construction waste cannot be disposed of at these facilities. However,
facilities located in Byron (Byron Crushing & Grinding Services and Woodmill Recycling
Company) and the Mt. Diablo Recycling Center & Transfer Station in Pittsburg can accept
construction and demolition material for proper recycling.
State and local diversion requirements (further described in Impact 3.14-5) for construction
materials and operational waste would apply to the proposed project, significantly reducing the
amount of daily waste. Therefore, the proposed project can be adequately served by existing
landfills and solid waste facilities with sufficient permitted capacity to accommodate its solid
waste disposal needs, so impacts would be less than significant.
Impact 3.14-5. The Project would comply with federal, state, and local statutes and
regulations related to solid waste. (Less than Significant)
The proposed project would be required to comply with the California Integrated Solid Waste
Management Act (AB 939) as well as state goals for recycling (AB 341) and organics diversion (AB
1826 and SB 1383). The project is also subject to County General Plan Policy 7-91, which encourages
solid waste resource recovery, and Policy 7-92, which encourages the diversion of waste from landfills
to extend the life of existing landfills; and Division 418 of the County Municipal Code. The proposed
project would dispose of all solid, non-recyclable waste at authorized sites, such as landfills (see Impact
3.14-4). All contractors hauling waste for construction of the proposed project would be required to
comply with County Ordinance 2004-16, which requires the reduction of construction and demolition
debris to landfills. Airport tenants are required to contract with qualified waste management services.

The proposed project would have a less-than-significant impact regarding compliance with all
applicable solid waste regulations.
3.14.5 Mitigation Measures
MM-UTIL-1 Prior to (1) the development of non-aviation uses, or (2) the expansion of aviation
uses that would increase water demand in excess of the current airport well system,
Contra Costa County (County) shall take one of the following actions:
a. Construct additional on-airport wells and water treatment facilities to
support the proposed development. The project Water Supply Assessment
estimates that up to four wells may be required to support buildout of the
development program. The County shall obtain a water supply permit from
the State Water Resource Control Board Division of Drinking Water, a well
drilling permit from Contra Costa County Environmental Health Division,
and all other applicable permits and approvals prior to development.
b. Obtain an off-site potable water supply from the Byron-Bethany Irrigation
District or the Town of Discovery Bay. The County shall not permit
development to proceed until the appropriate agreements or will-serve letters
have been obtained from the chosen supplier(s) and plans for construction of
necessary transmission lines have been approved by the County.
MM-UTIL-2 Prior to (1) the development of non-aviation uses or (2) the expansion of aviation
uses that involve additional human occupancy, Contra Costa County shall take one
of the following actions:
a. Expand the on-site septic system to accommodate forecasted development
wastewater flows. A permit from Contra Costa County Environmental
Health Division (CCCEHD)shall be obtained prior to development.
b. Construct an on-site package wastewater plant. The plant design, which
demonstrates adequate capacity for the development program, must be
approved by the CCCEHD. Prior to approval of development, Water
Discharge Requirements (WDR) must be approved by the Regional Water
Quality Control Board.
c. Obtain service from the Town of Discovery Bay or Byron Sanitary District.
The County must confirm with the provider that there is adequate service
capacity, and obtain a will serve letter for airport development. Plans for
construction of a sewer transmission line to the off-site provider must be
approved by all responsible County agencies.

3.14.6 Level of Significance After Mitigation
With implementation of MM-UTIL-1, MM-UTIL-2, and MM-HYD-1 (see Section 3.8), Impact
3.14-1 would be reduced to less than significant. Impact 3.14-2 would be reduced to less than
significant with implementation of MM-UTIL-1. Impact 3.14-3 would be reduced to less than
significant with implementation of MM-UTIL-2.
Indirect Impacts
Implementation of MM-UTIL-1 and MM-UTIL-2 may result in secondary impacts to the environment.
Implementation of these mitigation measures would require construction of additional on-site and/or
off-site infrastructure. To the extent that additional on-site infrastructure, such as on-site water or
wastewater treatment facilities, pump stations, and water storage facilities, would be required, this EIR
assumes full build-out of the aviation and airport-related development areas, including supportive
infrastructure. Off-site provision of water or wastewater service would require construction of
transmission lines. The most likely pipeline route from Byron Airport to the community of Byron
(Armstrong Road to Byron Highway) were considered, and no substantial environmental constraints
were noted. The construction of water and sewer transmission lines were included in the air quality
and greenhouse gas analyses assumptions (see Sections 3.2 and 3.6 of this EIR). Only unusual project
or site circumstances, per CEQA Guidelines Sections 15152(d) and 15168(c), would require additional
environmental review of this project-supportive infrastructure.
The following mitigation measures would apply to the construction of off-site infrastructure that
may be built in compliance with MM-UTIL-1 and MM-UTIL-2:
• MM-BIO-1 and MM-BIO-6 (see Section 3.3)
• MM-CUL-1, MM-CUL-2, and MM-CUL-3 (see Section 3.4)
• MM-NOI-1 (see Section 3.10)
The impact of providing utilities to the proposed project would be less than significant with
implementation of all applicable mitigation measures.
3.14.7 Cumulative
Cumulative impacts to utilities may occur when project demand, in addition to existing and future
users, exceeds the capacity of utility systems, resulting in the need for new or expanded facilities,
the construction of which may have a significant effect on the environment.
Construction of on-site utility systems, including water, wastewater, and stormwater, would serve
only Byron Airport. No off-site users would contribute to demand for these utilities. Therefore, no
cumulative impact would occur for on-site utilities. The proposed project may receive water and
3.14 – UTILITIES
Byron Airport Development Program EIR 9269
February 2022 3.14-24
wastewater service from off-site providers, including the BBID, Byron Sanitary District, and Town
of Discovery Bay. These providers develop plans, including Urban Water Master Plans and Sewer
Master Plans, consistent with growth assumptions used by the County to plan for future service
demands. MM-UTIL-1 and MM-UTIL-2 provide that any water or wastewater system that
provides service to the proposed project would only be used if feasibility studies demonstrate that
adequate cumulative capacity exists. Therefore, no cumulative impact would occur for provision
of off-site utilities.

3.15 ENERGY CONSUMPTION
The California Environmental Quality Act (CEQA) provides that an Environmental Impact Report
(EIR) must include a detailed statement identifying all significant effects on the environment of a
proposed project, and mitigation measures proposed to minimize significant effects on the
environment, including “measures to reduce the wasteful, inefficient, and unnecessary
consumption of energy” (California Public Resources Code Section 21100[b][1],[3]).
Appendix F of the CEQA Guidelines, Energy Conservation, provides recommendations for
information that should be included in an EIR to ensure that “energy implications are considered
in project decisions” (14 California Code of Regulations [CCR] 15000 et seq.). Appendix F directs
that EIRs should include “discussion of the potential energy impacts of proposed projects, with
particular emphasis on avoiding or reducing inefficient, wasteful and unnecessary consumption of
energy (California Public Resources Code Section 21100[b][3]) (14 CCR 15000 et seq.).”
Appendix F of the CEQA Guidelines lists potential energy impacts that may be relevant to the
energy conservation analysis in an EIR. Where a listed item is applicable or relevant to a project,
the EIR should consider it. This analysis for the proposed Byron Airport Development Program
(project) applied the following relevant listed items from Appendix F, subdivision (II)(F)(C), to
the discussion of impacts: energy requirements and energy use efficiencies of the proposed project
by fuel type and amount for each stage of the project, the effects of the project on local and regional
energy supplies and on requirements for additional capacity, the effects of the project on peak and
base period demands for electricity and other forms of energy, compliance with existing energy
standards, the effects of the project on energy resources, and the project’s projected transportation
energy use requirements and overall use of efficient transportation alternatives.
The 2018 update to the CEQA Guidelines includes Section 15126.2(b), which considers impacts
resulting from project energy use. The updated guidelines specify that an EIR must analyze project
energy use and mitigate energy use if a project may result in significant impacts due to wasteful,
inefficient, or unnecessary energy consumption, or wasteful use of energy resources. The analysis
should include energy consumption for all project phases and components, and include
transportation-related energy use. In addition to compliance with the California Building Code,
other project features such as project size, location, orientation, equipment use, and renewable
energy features should be considered in the analysis.
In accordance with Section 15126.2(b) of the updated CEQA Guidelines and with Appendix F of
the CEQA Guidelines, this EIR provides relevant information and analyses that address the energy
implications of the proposed project. This section presents a summary of the proposed project’s
anticipated energy needs, impacts, and conservation measures. The proposed project’s energy
needs were estimated using California Emissions Estimator Model (CalEEMod) outputs (see
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-2
Appendix C of this EIR). This emissions model contains typical electricity use and natural gas use
for a range of land uses, and estimates for the number of vehicle trips that may be associated with
construction and operation of the proposed project. This section summarizes the energy use
estimates of the proposed project and compares them to those of the existing on-site land uses, to
regional and local supply and demand under existing conditions, and to regional and local supply
and demand that has been forecasted for the future.
3.15.1 Existing Conditions
The proposed project, including vehicular trips to and from the project site, would result in the
consumption of energy in a variety of forms, namely electricity, natural gas, and petroleum.
Appendix F of the CEQA Guidelines, Part II, Section B, states that the “Environmental Setting
may include existing energy supplies and energy use patterns in the region and locality.”
Consistent with this recommendation, this subsection characterizes existing energy supplies and
energy use patterns for electricity, natural gas, and petroleum.
3.15.1.1 Electricity
According to the California Energy Commission (CEC) California Energy Demand Revised
Forecast 2018–2030, California used approximately 285,701 gigawatts per hour (GWh) of
electricity in 2016 (CEC 2018a). CEC’s Energy Consumption Database states that in 2017,
electricity consumption in California totaled approximately 288,614 GWh (CEC 2018b).
Electricity usage in California for different land uses varies substantially by the types of uses in a
building, type of construction materials used in a building, and the efficiency of all electricity-
consuming devices within a building. Due to the state’s energy efficiency standards and efficiency
and conservation programs, California’s per-capita electricity use has remained stable for more
than 40 years, while the national average has steadily increased (CEC 2018c).
Pacific Gas & Electric Company (PG&E) provides electricity to the community of Byron,
including the project site. PG&E, a subsidiary of PG&E Corporation, provides natural gas and
electric service to approximately 16 million customers across a 70,000-square-mile service area
(PG&E 2017). According to the CEC, approximately 104,148 GWh of electricity was used in
PG&E’s service area in 2017 (CEC 2018d). Demand forecasts anticipate that approximately
124,805 GWh of electricity will be used in PG&E’s service area in 2029, the estimated year of
project operation (CEC 2018a).
PG&E receives electric power from a variety of sources. According to PG&E’s 2017 Annual
Report, 33.1% of PG&E’s power came from eligible renewables in 2017, such as solar, wind,
geothermal, biomass power, and Renewables Portfolio Standard (RPS)-eligible hydroelectric
(PG&E 2017). This is an increase from the 28% that PG&E maintained for the 2014–2016
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-3
compliance period (CPUC 2016). The CEC estimates that approximately 29% of the state’s
electricity generation in 2017 came from renewable energy (CEC 2018e).
The RPS Program establishes a goal for California to increase the amount of electricity generated
from renewable energy resources to 20% by 2010 and to 33% by 2020. Recent legislation revised
the current RPS target for California to obtain 50% of total retail electricity sales from renewable
sources by 2030, with interim targets of 40% by 2024 and 45% by 2027.
Within Contra Costa County (County), annual non-residential electricity use is approximately 6,809
GWh per year, as reported by the state’s Energy Consumption Database for 2017 (CEC 2018f).
Electrical power is currently supplied to the project site by PG&E via a 12-kilovolt line in Holey
Road. It is anticipated that the proposed project would obtain electrical service from this existing
conduit and that this line is sufficient to supply power to the proposed project.
3.15.1.2 Natural Gas
According to the CEC, California used approximately 12,571 million therms1 of natural gas in
2017 (CEC 2018g). By sector, industrial uses utilize 35.9% of the state’s natural gas, followed by
35.5% for electric power, 16.9% for residential uses, 10.1% for commercial uses, and 1.6% fo r
transportation uses (EIA 2019a). Although the supply of natural gas in the United States and
production in the lower 48 states has increased greatly since 2008, California produces little, and
imports 90% of its supply of natural gas (CEC 2019). Gas supplies are generally imported via
pipelines from the Southwest, the Rocky Mountains, and Canada.
PG&E provides the community of Byron and the County with natural gas service. During the
winter, most natural gas resources are imported from Canada on a supply-and-demand basis, and
the balance is supplied from California production wells. During the summer, this ratio is reversed.
During the summer, when gas prices are lower, gas is stored in underground holders for use during
winter peak-use periods. In 2017, PG&E purchased approximately 291,000 million cubic feet2 of
natural gas, the majority of which was purchased under contracts with a term of 1 year or less
(PG&E 2017).
In the California mid-energy demand scenario, natural gas demand is projected to have an annual
growth rate of 0.43% in PG&E’s service territory from 2016 to 2030. As of 2017, approximately
4,743 million therms was used in PG&E’s service area per year (CEC 2018h). Around the time of
project operation in 2029, natural gas demand is anticipated to be approximately 4,865 million
therms per year in PG&E’s service area (CEC 2018i).
1 One therm is equal to 100,000 British thermal units (BTUs) or 100 kBTU.
2 One cubic foot of natural gas has approximately 1,020 BTUs of natural gas or 1.02 kBTUs of natural gas.
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-4
The total capacity of natural gas available to PG&E in 2018 is estimated to be 5,200 million cubic
feet per day. In 2020, the total capacity available is estimated to be 4,317 million cubic feet per
day (California Gas and Electric Utilities 2018). This amount is approximately equivalent to 44
million therms per day, or 4,398,950 mBritish thermal units (mmBTU). Over a year, the available
capacity would, therefore, be approximately 17 billion therms per year, which is well above the
existing and future anticipated natural gas demand in PG&E’s service area. Within the County,
annual natural gas consumption is approximately 946 million therms for non-residential uses, and
1,118 million therms in total (CEC 2018j).
Currently, there is no natural gas service provided to the project site. However, there is a PG&E
high-pressure natural gas transmission line that crosses Runway 5-23.
3.15.1.3 Petroleum
Transportation accounts for nearly 40% of California’s energy consumption according to the CEC
(2013). In California, petroleum fuels refined from crude oil are the dominant source of energy for
transportation sources. According to the U.S. Energy Information Administration, California used
approximately 672 million barrels of petroleum in 2016 (EIA 2019b). This equates to a daily use
of approximately 1.8 million barrels of petroleum. There are 42 U.S. gallons in a barrel, so
California consumes approximately 76 million gallons of petroleum per day, adding up to an
annual consumption of 28 billion gallons of petroleum.
By sector, transportation accounts for 85.5% of California’s petroleum consumption, followed by
11.1% for industrial uses, 2.5% for commercial, 1% for residential, and 0.01% for electric power
uses (EIA 2019b). Petroleum usage in California includes petroleum products such as motor
gasoline, distillate fuel, liquefied petroleum gases, and jet fuel. Production of petroleum in the
United States was 20 million barrels per day in 2016, which equates to 840 million gallons per
year (EIA 2019b). California has implemented policies to improve vehicle efficiency and to
support use of alternative transportation, which are described in Section 3.15.2, Relevant Plan,
Policies, and Ordinances. As such, the CEC anticipates an overall decrease of gasoline demand in
the state over the next decade (CEC 2018a).
3.15.2 Relevant Plan, Policies, and Ordinances
3.15.2.1 Federal
Federal Energy Policy and Conservation Act
In 1975, Congress enacted the Federal Energy Policy and Conservation Act, which established the
first fuel economy standards for on-road motor vehicles in the United States. Pursuant to the act,
the National Highway Traffic Safety Administration is responsible for establishing additional
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-5
vehicle standards. In 2010, fuel economy standards were set at 27.5 miles per gallon for new
passenger cars and 23.5 miles per gallon for new light trucks. Fuel economy is determined based
on each manufacturer’s average fuel economy for the fleet of vehicles available for sale in the
United States.
Energy Independence and Security Act of 2007
On December 19, 2007, the Energy Independence and Security Act of 2007 (EISA) was signed
into law. In addition to setting increased Corporate Average Fuel Economy (CAFE) standards for
motor vehicles, the act includes other provisions related to energy efficiency:
• Renewable Fuel Standard (RFS) (Section 202)
• Appliance and Lighting Efficiency Standards (Sections 301–325)
• Building Energy Efficiency (Sections 411–441)
This federal legislation requires ever-increasing levels of renewable fuels to replace petroleum
(Section 202, Renewable Fuel Standard). The U.S. Environmental Protection Agency (EPA) is
responsible for developing and implementing regulations to ensure that transportation fuel sold in
the United States contains a minimum volume of renewable fuel. The RFS Program regulations were
developed in collaboration with refiners, renewable fuel producers, and many other stakeholders.
The RFS Program was created under the Energy Policy Act of 2005 and established the first
renewable fuel volume mandate in the United States. As required under the act, the original RFS
Program (RFS1) required 7.5 billion gallons of renewable fuel to be blended into gasoline by 2012.
Under the EISA, the RFS Program was expanded in several key ways that laid the foundation for
achieving significant reductions of greenhouse gas (GHG) emissions through the use of renewable
fuels, for reducing imported petroleum, and for encouraging the development and expansion of the
renewable fuels sector in the United States. The updated program is referred to as RFS2 and
includes the following:
• EISA expanded the RFS Program to include diesel, in addition to gasoline.
• EISA increased the volume of renewable fuel required to be blended into transportation
fuel from 9 billion gallons in 2008 to 36 billion gallons by 2022.
• EISA established new categories of renewable fuel and set separate volume requirements
for each one.
• EISA required the EPA to apply lifecycle GHG performance threshold standards to ensure
that each category of renewable fuel emits fewer GHGs than the petroleum fuel it replaces
(EPA 2015).

Additional provisions of the EISA address energy savings in government and public institutions,
promoting research for alternative energy, additional research in carbon capture, international
energy programs, and the creation of “green jobs.”
Clean Power Plan and New Source Performance Standards for Electric Generating Units
On October 23, 2015, the EPA published a final rule (effective December 22, 2015) establishing
Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Utility Generating
Units (80 Federal Register [FR] 64510–64660), also known as the Clean Power Plan. These
guidelines prescribe how states must develop plans to reduce GHG emissions from existing fossil-
fuel-fired electric generating units. The guidelines establish carbon dioxide (CO2) emission
performance rates representing the best system of emissions reduction for two subcategories of
existing fossil-fuel-fired electric generating units: (1) fossil-fuel-fired electric utility steam-
generating units and (2) stationary combustion turbines. The rule includes state-specific CO2 goals
reflecting the CO2 emission performance rates and guidelines for the development, submittal, and
implementation of state plans that establish emission standards or other measures to implement
the CO2 emission performance rates. Initial plan compliance with state emissions goals begins in
2022, with full compliance with final goals required by 2030. The goals are established by state in
units of pounds of CO2 per net megawatt-hour or total short tons of CO2. For California, the goals
for 2030 are 828 pounds of CO2 per net megawatt-hour, or 96.8 million short tons of CO2. The
California Air Resources Board (CARB) anticipates that the state’s plan will rely heavily on
existing programs such as the Cap-and-Trade Program, RPS, energy efficiency standards, and the
Mandatory GHG Reporting Regulation (for compliance determinations) (CARB 2015).
Concurrently, the EPA published a final rule (effective October 23, 2015) establishing Standards
of Performance for Greenhouse Gas Emissions from New, Modified, and Reconstructed Stationary
Sources: Electric Utility Generating Units (80 FR 64661–65120). The rule prescribes CO2
emissions standards for newly constructed, modified, and reconstructed affected fossil-fuel-fired
electric utility generating units. Separate standards of performance were set for fossil-fuel-fired
electric utility steam-generating units and fossil-fuel-fired stationary combustion turbines. The
standards apply to new units commencing construction after January 8, 2014, or existing units
commencing modification or reconstruction after June 18, 2014. The rule applies only to units
with a base load rating greater than 250 million BTUs of fossil fuel per hour and serving a generator
or generators capable of selling greater than 25 megawatts of electricity to a utility power
distribution system. Implementation of the Clean Power Plan has been stayed by the U.S. Supreme
Court pending resolution of several lawsuits.

Byron Airport Development Program EIR 9269
February 2022 3.15-7
EPA and NHTSA Joint Rule for Vehicle Standards
On April 1, 2010, the EPA and the National Highway Traffic Safety Administration (NHTSA)
announced a joint final rule to establish a national program consisting of new standards for light -
duty vehicles model years 2012 through 2016. The joint rule is intended to reduce GHG emissions
and improve fuel economy. The EPA promulgated the first-ever national GHG emissions standards
under the Clean Air Act, and NHTSA promulgated CAFE standards under the Energy Policy and
Conservation Act. This final rule follows the EPA and Department of Transportation’s joint
proposal on September 15, 2009, and is the result of the President Obama’s May 2009
announcement of a national program to reduce GHGs and improve fuel economy. The final rule
became effective on July 6, 2010 (EPA and NHTSA 2010).
The EPA GHG standards required new passenger cars, light-duty trucks, and medium-duty passenger
vehicles to meet an estimated combined average emissions level of 250 grams of CO2 per mile by
model year 2016, equivalent to 35.5 miles per gallon (mpg) if the automotive industry were to meet
this CO2 level through fuel economy improvements alone. The CAFE standards for passenger cars and
light trucks were phased in from 2012 to 2016, with the final standards equivalent to 37.8 mpg for
passenger cars and 28.8 mpg for light trucks, resulting in an estimated combined average of 34.1 mpg.
Together, these standards will cut GHG emissions by an estimated 960 million metric tons and 1.8
billion barrels of oil over the lifetime of the vehicles sold under the program. The rules will
simultaneously reduce GHG emissions, improve energy security, increase fuel savings, and provide
clarity and predictability for manufacturers (EPA and NHTSA 2010).
In August 2012, the EPA and NHTSA approved a second round of GHG and CAFE standards for
model years 2017 and beyond (EPA and NHTSA 2012). These standards will reduce motor vehicle
GHG emissions to 163 grams of CO2 per mile, which is equivalent to 54.5 mpg if this level were
achieved solely through improvements in fuel efficiency, for cars and light-duty trucks by model
year 2025. A portion of these improvements, however, will likely be made through improvements
in air-conditioning leakage and through use of alternative refrigerants, which would not contribute
to fuel economy. The first phase of the CAFE standards (for model years 2017 to 2021) require,
on an average industry fleet-wide basis, a range from 40.3 to 41.0 mpg by model year 2021. The
second phase of the CAFE program (for model years 2022 to 2025) is projected to require, on an
average industry fleet-wide basis, a range from 48.7 to 49.7 mpg by model year 2025. The second
phase of standards has not been finalized due to the statutory requirement that NHTSA set average
fuel economy standards not more than five model years at a time. The regulations also include
targeted incentives to encourage early adoption and introduction into the marketplace of advanced
technologies to dramatically improve vehicle performance, including the following:
• Incentives for electric vehicles, plug-in hybrid electric vehicles, and fuel cell vehicles
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269

• Incentives for hybrid technologies for large pickups and for other technologies that achieve
high fuel economy levels on large pickups
• Incentives for natural gas vehicles
• Credits for technologies with potential to achieve real -world GHG reductions and fuel
economy improvements that are not captured by the standards’ test procedures
3.15.2.2 State
Title 24 of the California Code of Regulations
Title 24 of the California Code of Regulations was established in 1978 and serves to enhance and
regulate California’s building standards. Energy consumption by new buildings in California is
regulated by the state Building Energy Efficiency Standards, included in Title 24. The efficiency
standards apply to new construction of residential and non-residential buildings, and regulate energy
consumed for heating, cooling, ventilation, water heating, and lighting. The building efficiency
standards are enforced through the local building permit process. Local government agencies may
adopt and enforce energy standards for new buildings, provided these standards meet or exceed those
provided in Title 24 guidelines. The standards are updated periodically to allow consideration and
possible incorporation of new energy-efficiency technologies and methods. The current Title 24
standards are the 2019 Title 24 Building Energy Efficiency Standards, which became effective
January 1, 2020. Title 24 also includes Part 11, California’s Green Building Standards
(CALGreen). CALGreen establishes minimum mandatory standards as well as voluntary standards
pertaining to the planning and design of sustainable site development, energy efficiency (in excess
of the California Energy Code requi rements), water conservation, material conservation, and
interior air quality. The 2019 CALGreen standards are the current applicable standards. For
nonresidential projects, some of the key mandatory CALGreen 2019 standards involve
requirements related to bicycle parking, designated parking for clean air vehicles, electric vehicle
(EV) charging stations, shade trees, water conserving plumbing fixtures and fittings, outdoor
potable water use in landscaped areas, recycled water supply systems, construction waste
management, excavated soil and land clearing debris, and commissioning (24 CCR Part 11).
Senate Bill 1368
On September 29, 2006, Governor Arnold Schwarzenegger signed into law Senate Bill (SB) 1368
(Perata, Chapter 598, Statutes of 2006). The law limits long-term investments in baseload
generation by the state’s utilities to those power plants that meet an emissions performance
standard jointly established by the CEC and the California Public Utilities Commission.
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269

The CEC has designed regulations that do the following (Perata, Chapter 598, Statutes of 2006):
• Establish a standard for baseload generation owned by, or under long-term contract to,
publicly owned utilities of 1,100 pounds CO2 per megawatt-hour. This would encourage
the development of power plants that meet California’s growing energy needs while
minimizing their emissions of GHGs.
• Require posting of notices of public deliberations by publicly owned utilities on long-term
investments on the CEC website. This would facilitate public awareness of utility efforts
to meet customer needs for energy over the long-term while meeting the state’s standards
for environmental impact.
• Establish a public process for determining the compliance of proposed investments with
the emissions performance standard.
Assembly Bill 1493
Adopted in 2002 by the state legislature, AB 1493 (“Pavley” regulations) required that CARB
develop and adopt, no later than January 1, 2005, regulations to achieve the maximum feasible and
cost-effective reduction of GHG emissions from motor vehicles.
The first California request to implement GHG standards for passenger vehicles, known as a
waiver request, was made in December 2005 and was denied by the EPA in March 2008. That
decision was based on a finding that California’s request to reduce GHG emissions from passenger
vehicles did not meet the Clean Air Act requirement of showing that the waiver was needed to
meet “compelling and extraordinary conditions.”
The EPA granted California the authority to implement GHG emissions reduction standards for
new passenger cars, pickup trucks, and sport utility vehicles on June 30, 2009. On September 24,
2009, CARB adopted amendments to the Pavley regulations that reduce GHG emiss ions in new
passenger vehicles from 2009 through 2016. These amendments are part of California’s
commitment to a nationwide program to reduce new passenger-vehicle GHGs from 2012 through
2016. CARB’s September 2009 amendments will allow for California’s enforcement of the Pavley
rule while providing vehicle manufacturers with new compliance flexibility. The amendments also
prepare California to harmonize its rules with the federal rules for passenger vehicles.
It is expected that the Pavley regulations will reduce GHG emissions from California passenger
vehicles by approximately 22% in 2012 and 30% in 2016 while also improving fuel efficiency and
reducing motorists’ costs.

Executive Order S-1-07
Issued on January 18, 2007, Executive Order S-1-07 set a declining Low Carbon Fuel Standard
for GHG emissions measured in CO2 equivalent grams per unit of fuel energy sold in California.
The target of the Low Carbon Fuel Standard is to reduce the carbon intensity of California
passenger vehicle fuels by at least 10% by 2020. The carbon intensity measures the amount of
GHG emissions in the lifecycle of a fuel, including extraction/feedstock production, processing,
transportation, and final consumption, per unit of energy delivered. CARB adopted the
implementing regulation in April 2009. The regulation is expected to increase production of
biofuels, including those from alternative sources, such as algae, wood, and agricultural waste. In
addition, the Low Carbon Fuel Standard would drive the availability of plug-in hybrid, battery
electric, and fuel-cell power motor vehicles. The Low Carbon Fuel Standard is anticipated to lead
to the replacement of 20% of the fuel used in motor vehicles with alternative fuels by 2020.
Senate Bill 375
In August 2008, the legislature passed, and on September 30, 2008, Governor Schwarzenegger
signed, SB 375 (Steinberg), which addresses GHG emissions associated with the transportation
sector through regional transportation and sustainability plans. Regional GHG reduction targets
for the automobile and light-truck sector for 2020 and 2035, as determined by CARB, are required
to consider the emissions reductions associated with vehicle emissions standards (see SB 1493),
the composition of fuels (see Executive Order S-1-07), and other CARB-approved measures to
reduce GHG emissions. Regional Metropolitan Planning Organizations (MPOs) are responsible
for preparing a Sustainable Communities Strategy (SCS) within their Regional Transportation
Plan. The goal of the SCS is to establish a development plan for the region, which, after considering
transportation measures and policies, will achieve, if feasible, the GHG reduction targets. If an
SCS is unable to achieve the GHG reduction target, an MPO must prepare an alternative planning
strategy demonstrating how the GHG reduction target would be achieved through alternative
development patterns, infrastructure, or additional transportation measures or policies. SB 375
provides incentives for streamlining CEQA requirements by substantially reducing the
requirements for “transit priority projects,” as specified in SB 375, and eliminating the analysis of
the impacts of certain residential projects on global warming and the growth-inducing impacts of
those projects when the projects are consistent with the SCS or alternative planning strategy.
In September 2010, CARB adopted the SB 375 targets for the regional MPOs. The Metropolitan
Transportation Commission is the MPO for nine counties within the San Francisco Bay Area,
including the County. The targets for the Metropolitan Transportation Commission are a per-capita
reduction of GHG emissions by 7% by 2020 and by 15% by 2035. Achieving these goals through
adoption of an SCS is the responsibility of the MPOs. The Metropolitan Transportation
Commission prepared its original Regional Transportation Plan/SCS, titled Plan Bay Area, in July

2013. The region’s current Regional Transportation Plan/SCS covers 2017–2030 and was adopted
on July 26, 2017.
Truck and Bus Regulation, On-Road Heavy-Duty Diesel Vehicles (In-Use) Regulation
On December 12, 2008, CARB approved the Truck and Bus Regulation to significantly reduce
particulate matter and nitrogen oxide emissions from existing diesel vehicles operating in
California. Amendments to this regulation were approved by CARB on April 25, 2014.
The regulation applies to nearly all diesel-fueled, dual-fueled, or alternative diesel-fueled trucks
and buses with a gross vehicle weight rating greater than 14,000 pounds that are privately or
federally owned, and to privately and publicly owned school buses. The purpose of this regulation
is to reduce emissions of diesel particulate matter, nitrogen oxides, and other criteria pollutants
from in-use diesel-fueled vehicles.
Heavier trucks and buses with a gross vehicle weight rating greater than 26,000 pounds must
comply with a schedule by engine model year, or owners can report to show compliance with more
flexible options. Starting January 1, 2012, heavier trucks were required to meet the engine model
year schedule shown in Table 3.15-1. Fleets that comply with the schedule must install the best
available particulate matter filter on 1996 model year and newer engines, and replace the vehicle
8 years later. Trucks with 1995 model year and older engines must be replaced starting in 2015.
Replacements with a 2010 model year or newer engines meet the final requirements, but owners
can also replace with used trucks that have a future compliance date on the schedule. For example,
a replacement with a 2007 model year engine complies until 2023. By 2023, all trucks and buses
must have 2010 model year engines with few exceptions. No reporting is required if complying
with this schedule (CARB 2014).

Advanced Clean Cars Program
In January 2012, CARB approved the Advanced Clean Cars program, a new emissions-control
program for model years 2015 through 2025. The program combines the control of smog- and
soot-causing pollutants and GHG emissions into a single coordinated package. The package
includes elements to reduce smog-forming pollution, reduce GHG emissions, promote clean cars,
and provide the fuels for clean cars (CARB 2011). To improve air quality, CARB created
emissions standards to reduce smog-forming emissions beginning with 2015 model year vehicles.
It is estimated that by 2025, cars will emit 75% less smog-forming pollution than the average new
car sold in 2011 (CARB 2011). To reduce GHG emissions, CARB, in conjunction with the EPA
and NHTSA, adopted GHG standards for model year 2017 to 2025 vehicles; these standards are
estimated to reduce GHG emissions by 34% by 2025. The Zero-Emissions Vehicles Program will
act as the focused technology of the Advanced Clean Cars program by requiring manufacturers to
produce increasing numbers of zero-emissions vehicles (ZEVs) and plug-in hybrid electric
vehicles in the 2018 to 2025 model years. The Clean Fuels Outlet regulation will ensure that fuels
such as electricity and hydrogen are available to meet the fueling needs of the advanced technology
vehicles as they come to the market.
Executive Order B-16-12
Governor Brown issued Executive Order S-16-12 on March 23, 2012. The executive order requires
that state entities under the governor’s direction and control support and facilitate the rapid
commercialization of ZEVs. It ordered CARB, the CEC, the California Public Utilities Commission,
and other relevant agencies to work with the Plug-in Electric Vehicle Collaborative and the California
Fuel Cell Partnership to establish benchmarks to help achieve the following by 2015:
• The state’s major metropolitan areas will be able to accommodate ZEVs, each with
infrastructure plans and streamlined permitting
• The state’s manufacturing sector will be expanding ZEV and component manufacturing
• The private sector’s investment in ZEV infrastructure will be growing
• The state’s academic and research institutions will be contributing to ZEV research,
innovation and education
CARB, the CEC, and the California Public Utilities Commission, are also directed to establish
benchmarks to help achieve the following goals by 2020:
• The state’s ZEV infrastructure will be able to support up to 1 million vehicles
• The costs of ZEV will be competitive with conventional combustion vehicles
• ZEVs will be accessible to mainstream consumers
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-13
• There will be widespread use of ZEVs for public transportation and freight transport
• Transportation sector GHG emissions will be falling as a result of the switch to ZEVs
• Electric vehicle charging will be integrated into the electricity grid
• The private sector’s role in the supply chain for ZEV component development and
manufacturing will be expanding
Benchmarks are also to be established to help achieve the following goals by 2025:
• More than 1.5 million ZEVs will be on California roads and their market share will be expanding
• Californians will have easy access to ZEV infrastructure
• The ZEV industry will be a strong and sustainable part of California’s economy
• California’s clean, efficient vehicles will annually displace at least 1.5 billion gallons of
petroleum fuels
On a statewide basis, Executive Order S-16-12 establishes a target reduction of GHG emissions
from the transportation sector equaling 80% less than 1990 levels by 2050.
Cap-and-Trade Program
To achieve the goals of AB 32, the Climate Change Scoping Plan: A Framework for Change
included an early action to develop a California cap-and-trade program that links with other
Western Climate Initiative partner programs to create a regional market system (CARB 2008). The
cap-and-trade program, which is a key element of California’s climate plan, took effect in January
2012, and compliance obligation began in January 2013. The cap-and-trade program sets a
statewide limit on sources responsible for 85% of California’s GHG emissions, and establishes a
price signal needed to drive long-term investment in cleaner fuels and more efficient use of energy.
The cap-and-trade program is designed to provide covered entities the flexibility to seek out and
implement the lowest-cost options to reduce emissions. The first phase of the cap-and-trade
regulation included electricity generated in and imported into California, large combustion sources
(i.e., generally those emitting more than 25,000 metric tons of CO2 equivalent per year), and certain
industrial sectors. The second phase added providers of transportation fuels and other combustion
fuels (e.g., natural gas, propane) to the cap-and-trade program. The regulation requires that
emissions generated by these facilities and combustion of fuels be reduced over time under a
declining “cap.”
Renewable Energy Sources
Established in 2002 under SB 1078 and accelerated by SB 107 (2006) and SB 2 (2011),
California’s RPS obligates investor-owned utilities, energy service providers, and community
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-14
choice aggregators to procure 33% of their electricity from renewable energy sources by 2020.
Eligible renewable resources are defined in the 2013 RPS to include biodiesel; biomass;
hydroelectric and small hydro (30 megawatts or less); Los Angeles Aqueduct hydro power plants;
digester gas; fuel cells; geothermal; landfill gas; municipal solid waste; ocean thermal, ocean wave,
and tidal current technologies; renewable-derived biogas; multifuel facilities using renewable
fuels; solar photovoltaic; solar thermal electric; wind; and other renewables that may be defined
later. Governor Jerry Brown signed SB 350 on October 7, 2015, which expanded the RPS by
establishing a goal of 50% of the total electricity sold to retail customers in California per year by
December 31, 2030. In addition, SB 350 includes the goal to double the energy efficiency savings
in electricity and natural gas final end uses (such as heating, cooling, lighting, or class of energy
uses upon which an energy efficiency program is focused) of retail customers through energy
conservation and efficiency. The bill also requires the California Public Utilities Commission, in
consultation with the CEC, to establish efficiency targets for electrical and gas corporations
consistent with this goal. SB 350 also provides for the transformation of the California Independent
System Operator into a regional organization to promote the development of regional electricity
transmission markets in the western states, and to improve the access of consumers served by the
California Independent System Operator to those markets, pursuant to a specified process.
SB 100 (2018) increased the standards set forth in SB 350 establishing that 44% of the total
electricity sold to retail customers in California per year by December 31, 2024, 52% by December
31, 2027, and 60% by December 31, 2030, be secured from qualifying renewable energy sources.
SB 100 states that it is the policy of the state that eligible renewable energy resources and zero -
carbon resources supply 100% of the retail sales of electricity to California by 2045. This bill
requires that the achievement of 100% zero-carbon electricity resources do not increase the carbon
emissions elsewhere in the western grid, and that the achievement not be achieved through
resource shuffling.
According to PG&E’s 2017 Annual Report, 33.1% of PG&E’s power came from eligible
renewables in 2017 (PG&E 2017). This means that PG&E has already met the 33% renewable
source requirement before 2020. This represents the off-site renewable sources available to the
project through electricity provided by PG&E.

energy consumption, increasing on-site energy generation, reducing
fugitive dust emissions, and contributing toward development of
renewable energy projects in impacted communities.
Contra Costa County Climate Action Plan
In 2015, the County adopted the Contra Costa County Climate Action Plan (CAP), which provides
a GHG emissions inventory, a GHG forecast, a GHG reduction target, and a set of strategies to
respond to local contributions to climate change. Based on the state CEQA Guidelines and Bay
Area Air Quality Management District criteria, the CAP is considered a qualified GHG reduction
strategy (Contra Costa County 2015). The CAP establishes the County GHG reduction goal of
reducing GHGs by 15% below 2005 levels by 2020, consistent with AB 32. In addition, the CAP
forecasts the potential GHG emissions and potential GHG reductions from proposed measures
through 2035. The CAP outlines the reduction efforts in six major GHG source areas: energy
efficiency and conservation, renewable energy, land use and transportation, solid waste, water
conservation, and government operations. In addition, Appendix E of the County’s CAP provides
a consistency checklist through which projects can demonstrate consistency and thereby conclude
that their impacts related to GHG emissions would be less than significant under CEQA.
Contra Costa County Green Building
The County adopted the 2016 California Green Building Standards Code (CCR, Title 24, Part 11)
as part of its building code, and set forth changes, additions, and deletions to the 2016 California
Green Building Standards Code in Chapter 74-4, Division 72, of its Municipal Code. Amended
elements include Section 5.106.5.3, which sets forth requirements for the number of fully
operational electric vehicles for new non-residential construction, and Section 5.408.1.3, which
sets forth construction waste stream reduction requirements. The proposed project would be
required to comply with these provisions.
Contra Costa Countywide Bicycle and Pedestrian Plan
In 2003, the Contra Costa Transportation Authority adopted the Contra Costa Countywide Bicycle
and Pedestrian Plan (CBPP). The CBPP was updated in 2009 to address changes since the adoption
of the original CBPP, and again in 2018. The 2018 CBPP sets forth goals, objectives, and policy
actions to improve and facilitate bicycle and pedestrian transportation. The CBPP assessed the
needs of bicyclists and pedestrians in the County, and identified a set of Countywide improvements
that would encourage more people to walk and bicycle. The CBPP lays out the policy framework
for the implementation of an overall vision for the County that consists of the following
overarching goals (Contra Costa County 2018b):
• Encourage more people to walk and bicycle
• Increase safety and security for pedestrians and bicyclists
3.15 – ENERGY CONSUMPTION

• Create a safe, connected, and comfortable network of bikeways and walkways for all ages
and abilities
• Increase the livability and attractiveness of Contra Costa’s communities and districts
• Equitably serve all of Contra Costa’s communities while ensuring that public investments
are focused on projects with the greatest benefits
3.15.3 Thresholds of Significance
Section 15126.2(b) and Appendix F of the CEQA Guidelines provide guidance for evaluating
whether a development project may result in significant impacts with regard to energy. Based on
Section 15126.2(b) and Appendix F of the CEQA Guidelines, a project could have a significant
impact on energy consumption if the project would:
a. Result in wasteful, inefficient, or unnecessary consumption of energy, or wasteful use of
energy resources.
b. Conflict with existing energy standards and regulations.
c. Place a significant demand on local and regional energy supplies or require a substantial
amount of additional capacity.
Methodology
A brief overview of the methodology applied to assess the proposed project’s potential impacts is
provided below:
Electricity. Proposed project electricity usage data was determined using CalEEMod Version
2016.3.2. Electricity demand within PG&E’s service area was obtained from CEC reports
(specifically, the California Energy Demand 2018–2030 Revised Forecast and 2017 Integrated
Energy Policy Report [CEC 2018a, 2018c]) and the CEC Energy Consumption Database.
Electricity demand within the County was obtained from the CEC Energy Consumption Database.
Natural Gas. Proposed project on-site natural gas usage data was estimated using CalEEMod.
Regional natural gas demand data was obtained from the California Energy Demand Forecast and
CEC Energy Consumption Database. Natural gas demand within the County was obtained from
the CEC Energy Consumption Database. Information on natural gas supply was obtained from the
2018 California Gas Report.
Petroleum. Potential impacts were assessed through projected traffic trip generation during
construction and operation, as provided by the CalEEMod outputs (Appendix C of this EIR) and
the Traffic Impact Analysis Report that was prepared for the project (Appendix H). Fuel
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-19
consumption factors were obtained using CalEEMod assumptions. Detailed model outputs and
assumptions are included in Appendix C of this EIR.
3.15.4 Impacts Analysis
Impact 3.15-1. The project would not result in wasteful, inefficient, or unnecessary
consumption of energy, or wasteful use of energy resources. (Less
than Significant)
Implementation of the project would increase the demand for electricity and natural gas at the
project site and petroleum consumption in the project area during construction and operation
relative to existing uses.
Electricity
Construction Use
Temporary electric power for as-necessary lighting and electronic equipment such as computers
would be provided by PG&E. The electricity used for such activities would be temporary, would
be substantially less than that required for project operation, and would have a negligible
contribution to the project’s overall energy consumption.
Operational Use
The project would involve construction and operation of airport-related and aviation uses at Byron
Airport. The potential development may include up to 274,000 square feet of
logistics/warehouse/distribution buildings, 213,000 square feet of light industry/business park,
81,000 square feet of office uses, 91,000 square feet of commercial uses, 128,000 square feet of
airport storage, 154,000 square feet of aviation-related buildings, and associated parking. Existing
aviation facilities within Byron Airport include 10 acres of aircraft storage area, 4 acres of apron,
125,000 square feet of hangars, and 2,400 square feet of office space. The majority of these existing
facilities were constructed when the airport was built in the early 1990s.
The operational phase of the proposed project would require electricity for multiple purposes,
including building heating and cooling, lighting, appliances, and electronics. Additionally, the
supply, conveyance, treatment, and distribution of water, and the conveyance and/or disposal of
wastewater would indirectly result in electricity usage. CalEEMod was used to estimate project
emissions from electricity uses (see Appendix C for calculations). Default electricity generation
rates in CalEEMod were used (based on the proposed land use and climate zone) and adjusted
based on compliance with Title 24 standards for 2019. According to these estimations, the project
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-20
would consume approximately 8,741,078 kilowatt hours of electricity per year. This would be a
considerable increase in electricity use on the project site.
The electricity demand calculation for the proposed project assumes compliance with Title 24
standards for 2019, which aim to improve the energy efficiency of non-residential buildings.
The project’s impacts in the category of GHG emissions was determined to be potentially
significant because the proposed project would increase GHG emissions and would not meet the
following County CAP requirements (see Section 3.6, Greenhouse Gas Emissions, of this EIR)
(Contra Costa County 2015):
• EE 1: New nonresidential development will install high efficiency appliances and insulation.
• RE 1: New residential and nonresidential development will meet the standards to be solar
ready as defined by the California Building Standards Code.
• LUT 2: New multifamily (greater than five units) and nonresidential (greater than 10,000
square feet) developments will provide EV charging stations in designated parking spots.
• LUT 4: New residential and nonresidential development will be located within one half-mile
of a Bay Area Rapid Transit or Amtrak station, or within one quarter-mile of a bus station.
For the proposed project to meet the applicable CAP consistency checklist criteria, Mitigation
Measures (MM) GHG-1, MM-GHG-2, and MM-GHG-3 are proposed. MM-GHG-2 requires
implementation of design features that would reduce demand for energy use. This includes
obtaining Leadership in Energy and Environmental Design (LEED) Certification for building
construction where feasible, providing skylights to reduce electricity use, using energy-efficient
appliances, and designing proposed buildings to be solar-ready. Furthermore, MM-GHG-3
requires water conservation design features to be incorporated into the proposed project. These
measures address and reduce operational electricity usage from the proposed project (see Section
3.6 of this EIR for details).
Additionally, the proposed project would comply with County General Plan Policy 8-113, which
requires new commercial and industrial projects exceeding 10,000 square feet of gross floor area to
incorporate measures to reduce GHG emissions (Contra Costa County 2018a). County policy also
requires County-owned buildings to meet LEED Silver standards or higher. The aviation buildings
other than the hangars, which do not have heating or cooling, would meet County requirements. The
proposed project’s compliance with Title 24 standards, the County’s General Plan policies, and MM-
GHG-1 and MM-GHG-2 would reduce operational electricity usage resulting from the proposed
project. Therefore, the electricity consumption of the proposed project would not be considered
inefficient or wasteful, and impacts would be less than significant.

Natural Gas
Construction Use
Natural gas is not anticipated to be required during construction of the proposed project. Fuels
used for construction would primarily consist of diesel and gasoline, which are discussed below
under the “Petroleum” subheading. Any minor amounts of natural gas that may be consumed as a
result of project construction would be substantially less than that required for project operation
and would have a negligible contribution to the project’s overall energy consumption.
Operational Use
Operation of the proposed project would require natural gas for various purposes, including
building heating and cooling and service water heating. Default natural gas usage rates in
CalEEMod for the proposed land use and climate zone were used and adjusted based on
compliance with 2019 Title 24 standards (see Appendix C for calculations). According to these
estimations, the project would consume approximately 10,568,394 kBTU per year. The project
site does not currently use natural gas. Therefore, natural gas consumption at the project site would
substantially increase with the proposed project.
For the proposed project to meet the applicable CAP consistency checklist criteria, MM -GHG-1,
MM-GHG-2, and MM-GHG-3 are proposed (see Section 3.6 of this EIR). MM-GHG-2 requires
implementation of design features that would reduce demand for energy use. MM-GHG-3 requires
water conservation design features to be incorporated into the proposed project that would reduce
energy required for water heating. These measures would address and reduce operational natural
gas usage from the proposed project (see Section 3.6 of this EIR for details).
Additionally, the proposed project would comply with County General Plan Policy 8-113, which
requires new commercial and industrial projects exceeding 10,000 square feet of gross floor area
to incorporate measures to reduce GHG emissions (Contra Costa County 2018a). The proposed
project’s compliance with Title 24 standards, the County’s General Plan policies, and MM-GHG-
2 and MM-GHG-3 would reduce operational natural gas usage related to the proposed project.
Therefore, the natural gas consumption of the proposed project would not be considered inefficient
or wasteful, and impacts would be less than significant.
Petroleum
Construction Use
Heavy-duty construction equipment associated with construction activities for the proposed
project would rely on diesel fuel, as would haul trucks involved in removing the materials from
3.15 – ENERGY CONSUMPTION

February 2022 3.15-22
excavation. Construction workers would travel to and from the project site throughout
construction. It is assumed in this analysis that construction workers would travel to and from the
site in gasoline-powered passenger vehicles.
Heavy-duty construction equipment of various types would be used during each phase of project
construction. The CalEEMod analysis discussed in Section 3.2, Air Quality, and included in
Appendix C of this EIR lists the assumed equipment usage for each phase of construction. Based
on that analysis, over all phases of construction, diesel-fueled construction equipment would run
for an estimated 173,178 hours, as summarized in Table 3.15-2.

Fuel consumption from construction equipment was estimated by converting the total CO2
emissions from each construction phase to gallons using the conversion factors for CO2 to gallons
of gasoline or diesel. The conversion factor for gasoline is 8.78 kilograms per metric ton CO2 per
gallon, and the conversion factor for diesel is 10.21 kilograms per metric ton CO2 per gallon (The
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-23
Climate Registry 2019). The total estimated diesel fuel consumption from construction equipment
for development of the project would be 332,870 gallons.
The estimated GHGs from on-road vehicles were back-calculated based on carbon content (i.e.,
kilograms of CO2 per gallon) in order to estimate fuel usage during project construction. The
conversion factor for gasoline is 8.78 kilograms per metric ton CO2 per gallon, and the conversion
factor for diesel is 10.21 kilograms per metric ton CO2 per gallon (The Climate Registry 2019).
Based on CalEEMod estimates, approximately 1,160 one-way haul trips would be required over
the course of the construction period. The vehicle miles traveled (VMT) per trip is assumed to be
approximately 20 miles, equating to 23,200 VMT. Based on the carbon content of diesel, hauling
would consume approximately 3,998 gallons of petroleum.
In addition to haul trucks, vendor trucks would travel to and from the project site to deliver
materials. Based on CalEEMod estimates, approximately 336,672 one-way vendor truck trips
would occur over the construction period. VMT per trip is assumed to be approximately 13 miles,
equating to 4,376,736 VMT total (Appendix C). Based on the carbon content of diesel, vendor
trucks would consume approximately 674,392 gallons of petroleum during project construction.
Fuel would also be consumed by construction workers traveling to and from the project site
throughout the construction period. The number of construction workers required would vary based
on the construction phase and activity. Using CalEEMod estimates, construction would result in
865,088 one-way worker trips, and each trip would be 13 miles in length. As such, construction
worker commute trips would result in 11,246,144 VMT. Based on the carbon content of gasoline,
workers would consume approximately 362,308 gallons of petroleum during project construction.
This estimate is conservative given that it does not account for carpooling or use of public transit by
construction workers.
In summary, the proposed project is conservatively anticipated to consume approximately
1,373,567 gallons of petroleum during the construction phase, which would last approximately 10
years (extending approximately from January 2019 through December 2028). By comparison,
California’s consumption of petroleum is approximately 76 million gallons per day and
approximately 28 billion gallons of petroleum per year (EIA 2019b). Based on these assumptions,
approximately 280 billion gallons of petroleum would be consumed in California over the course
of the construction period. Construction of the proposed project would, therefore, equate to
0.0005% of the total amount of petroleum that would be used statewide during the course of the
construction period. Although construction activities would consume petroleum-based fuels,
consumption of such resources would be temporary and would cease upon completion of
construction. Further, the petroleum consumed related to project construction would be typical of
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-24
construction projects of similar types and sizes, and would not necessitate new petroleum resources
beyond what is typically required for California.
Operational Use
During operations, the majority of fuel consumption resulting from the proposed project would
involve the use of vehicles traveling to and from the project site. Traffic trips were estimated based
on the land uses specified in Chapter 2, Project Description, of this EIR, and by adjusting default
weekday trip rates in CalEEMod to match those included in the Transportation Impact Analysis
Report (Appendix H) for the land use types. The same adjustment factors used for the weekday
trip generation were applied to the default Saturday and Sunday trip rates in CalEEMod. Increased
trip lengths for potential customers based on the rural location of the project, as well as the project
specific vehicle-miles-traveled (VMT) for employees, are described in Chapter 3.13,
Transportation, of this EIR. Non-work trip lengths were increased to account for potentially greater
travel distance for deliveries. Project-related traffic was assumed to include a mixture of vehicles
in accordance with the model outputs for traffic. Annual operational gasoline demand and diesel
demand were quantified.
Gas fuel consumption associated with motor vehicles traveling to and from the project site is a
function of VMT as a result of project operation. As shown in Appendix C (CalEEMod outputs),
the annual VMT attributable to the proposed project is expected to be 39,193,242 (Appendix C).
Total estimated gasoline demand during project operation is approximately 1,131,713 gallons per
year, and total estimated diesel demand is approximately 297,758 gallons per year. By comparison,
California as a whole consumes approximately 28 billion gallons of petroleum per year (EIA
2019b). The anticipated increase in consumption associated with 1 year of project operation is
0.005% of the statewide use.
Over the lifetime of the project, the fuel efficiency of the vehicles visiting the project site is
expected to increase. As such, the amount of petroleum consumed as a result of vehicular trips to
and from the project site during operation would decrease over time. As discussed under Section
3.15.2, Relevant Plan, Policies, and Ordinances, numerous regulations are in place that require and
encourage increased fuel efficiency. For example, CARB has adopted an approach to passenger
vehicles by combining the control of smog-causing pollutants and GHG emissions into a single
package of standards. This approach also includes efforts to support and accelerate the number of
plug-in hybrids and ZEVs in California (CARB 2013). Additionally, in response to SB 375, CARB
adopted the goal of reducing per-capita GHG emissions from 2005 levels by 107% by 2020, and
18% by 2035 for light-duty passenger vehicles in the Association of Bay Area Governments
planning area, which includes the County (CARB 2018). As such, operation of the project is
expected to use decreasing amounts of petroleum over time due to advances in fuel economy. In
addition, for the proposed project to meet the applicable CAP consistency checklist criteria, MM-
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-25
GHG-1, MM-GHG-2, and MM-GHG-3 are proposed. MM-GHG-1 requires implementation of
transit-oriented and alternative transportation development design features into the project to
reduce the use of single-occupancy fossil-fueled vehicles and VMT. This measure addresses and
reduces operational GHG emissions resulting from the proposed project (see Section 3.6 of this
EIR for details).
The project site is located and the proposed project was designed to take advantage of the airport
and several nearby highways. By efficiently using County-owned land with access to multiple
transportation modes, the project, despite lacking transit access, is locationally efficient. In
addition, creating employment opportunities for the largely residential communities in the eastern
part of the County would be beneficial in terms of transportation energy by shortening commute
times (instead of going to job-rich areas such as the Bay Area). Given the restraints on residential
development related to airport operations, industrial, commercial, and aviation uses at this location
would not be a wasteful or inefficient use of energy resources.
In summary, although the proposed project would cause an increase in petroleum use during
construction and operation, vehicles would use less petroleum due to advances in fuel economy
over time. Furthermore, MM-GHG-1 would require implementation of design features that would
encourage electric vehicle and zero/low-emission vehicle use and promote ridesharing and
commute trip-reduction strategies. Given these considerations, the petroleum consumption
associated with the proposed project would not be considered inefficient or wasteful, and impacts
would be less than significant.
Impact 3.15-2. The project would not conflict with existing energy standards and
regulations. (Less than Significant Impact)
The proposed project would be subject to and would comply with the California Building Energy
Efficiency Standards (24 CCR, Part 6). Part 6 of Title 24 establishes energy efficiency standards
for residential and non-residential buildings constructed in California to reduce energy demand
and consumption. Part 11 of Title 24 sets forth voluntary and mandatory energy measures that are
applicable to the proposed project under the CALGreen. As discussed for Impact 3.15-1, the
project would result in an increased demand for electricity, natural gas, and petroleum. In
accordance with Title 24 Part 11 mandatory compliance, the proposed project would have (a) at
least 50% of its construction and demolition waste diverted from landfills; (b) mandatory
inspections of energy systems to ensure optimal working efficiency; (c) low-pollutant emitting
exterior and interior finish materials, such as paints, carpets, vinyl flooring and particle boards;
and (d) a 20% reduction in indoor water use. Furthermore, the proposed project would comply
with the County General Plan, including General Plan Policy 8-113, which requires new
commercial and industrial projects exceeding 10,000 square feet of gross floor area to incorporate
measures to reduce GHG emissions (Contra Costa County 2018a). County-owned buildings are
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-26
designed to meet a standard of LEED Silver or greater. Because the project would comply with
and exceed the existing energy standards and regulations, a less than significant impact would
result due to conflicts with energy standards and regulations.
Impact 3.15-3. The project would not place a significant demand on local and regional
energy supplies or require a substantial amount of additional capacity.
(Less than Significant)
Electricity
As described in Section 3.15.1, Existing Conditions, electricity is supplied to the project site by
PG&E. As of 2017, approximately 104,148 GWh of electricity was used in PG&E’s service area
annually (CEC 2018d). Annual retail sales of electricity in PG&E’s service area are forecasted to
be approximately 124,805 GWh in 2029 (CEC 2018a). Upon implementation of the proposed
project, the amount of electricity used at the project site is anticipated to increase by 8,741,078
kilowatt hours per year (Appendix C). This increase represents 0.008% of PG&E’s existing
demand and approximately 0.007% of PG&E’s total forecasted electricity sales in 2029 (near the
time of project buildout). As such, under both existing and future conditions, the increase in
electricity demand at the project site would be negligible relative to the electricity use in PG&E’s
service area. Furthermore, the increase in electricity demand at the project site would be
accommodated within the amount of electricity that PG&E is anticipated to provide in its service
area in 2029. Within the County, annual non-residential electricity use is approximately 6,809
GWh per year, as reported by the state’s Energy Consumption Database for 2017 (CEC 2018f).
The increase in electricity consumption associated with the proposed project represents
approximately 0.1% of the County’s total annual demand for non-residential uses. As such, the
increase in electricity usage in the County attributable to the proposed project would not constitute
a substantial amount that would place a significant demand on local and regional energy supplies,
or require a substantial amount of additional capacity.
Natural Gas
As described in Section 3.15.1, natural gas would be supplied to the project site by PG&E. As of
2017, approximately 4,743 million therms of natural gas were used in PG&E’s service area per
year (CEC 2018h). Around the time of project buildout in 2029, natural gas demand is anticipated
to be approximately 4,865 million therms per year in PG&E’s service area (CEC 2018i). The total
capacity available is anticipated to be 44 million therms per day. This equates to 17 billion therms
per year, which is well above both existing and future anticipated demand.
Upon implementation of the proposed project, the amount of natural gas used at the project site
per year is anticipated to increase by 10,463,756 kBTU relative to existing conditions. This amount
3.15 – ENERGY CONSUMPTION
Byron Airport Development Program EIR 9269
February 2022 3.15-27
of natural gas is equivalent to 104,638 therms.3 The expected increase in use represents
approximately 0.002% of PG&E’s existing 2017 demand and 0.002% of PG&E’s future 2029
demand. The increase in natural gas consumption attributable to the proposed project is
approximately 0.01% of the County’s annual natural gas demand for non-residential uses. As such,
the increase in natural gas usage in the County attributable to the proposed project would not
constitute a substantial amount that would place a significant demand on local and regional energy
supplies, or require a substantial amount of additional capacity.
Petroleum
The proposed project would increase the use of petroleum relative to existing conditions at the
project site. During the construction phase, it is anticipated that approximately 1,373,567 gallons
of petroleum would be used. This amount is approximately 0.0005% of the total amount of
petroleum that would be used statewide during the course of the construction period. During
operation, the increase in number of vehicles traveling to and from the project site would result in
petroleum consumption of 1,429,471 gallons per year. This equates to 0.005% of yearly gasoline
use throughout the state. As described in Section 3.15.1, the United States produces approximately
840 million gallons per year (EIA 2019b). The increase in petroleum use attributable to the
proposed project would be negligible relative to petroleum production in the United States.
Additionally, policies are in place at the state and federal levels to increase fuel efficiency over
time. Increasing efficiency of vehicles over the lifetime of the project is also anticipated to result
in incremental reductions in the project’s operational fuel use.
For the reasons described above, the proposed project’s energy use falls well within local and
regional energy supplies. The proposed project’s anticipated energy consumption would be
minimal relative to both existing energy consumption and future consumption at both the local and
regional scale. Further, as substantiated in the calculations above, the increase in electricity and
natural gas usage attributable to the proposed project falls within anticipated increases in PG&E’s
electricity and natural gas demands, and the proposed project would not create a significant
demand on supplies or require substantial additional capacity to provide electricity or natural gas
services. Regarding petroleum, fuel economy is expected to increase over time, and even without
such reductions in future petroleum use, petroleum use associated with the proposed project would
be negligible relative to current use and production. Therefore the proposed project would not
create a significant demand on petroleum supplies or require substantial additional petroleum
services capacity. Impacts would be less than significant.

3.15.5 Mitigation Measures
As discussed above, energy impacts related to the proposed project would be less than significant.
The project would comply with federal, state, and local policies and standards for conservation of
energy. County GHG reduction policies, which also serve to reduce energy demand, would be
ensured through implementation of MM-GHG-1, MM-GHG-2, and MM-GHG-3. No additional
mitigation measures are required.
3.15.6 Level of Significance After Mitigation
Impacts would be less than significant without implementation of additional mitigation measures.
3.15.7 Cumulative Impacts
Impact 3.15-3 considers future demand by energy uses. Impacts 3.15-1 and 3.15-2 would not be
affected by other projects, since the interaction with future development identified in the General
Plan would not affect the efficiency of the project or consistency with applicable plans.

ALTERNATIVES
4.1 INTRODUCTION
The purpose of the alternatives evaluation in an Environmental Impact Report (EIR), as stated in
Section 15126.6(c) of the California Environmental Quality Act (CEQA) Guidelines, is to ensure
that the range of potential alternatives to the proposed Byron Airport Development Program
(project) includes those that could feasibly accomplish most of the basic objectives of the project
and could avoid or substantially lessen one or more of the significant effects identified by the
proposed project. Pursuant to CEQA Guidelines Section 15126.6, an analysis of alternatives to the
proposed project is presented in this Draft EIR to provide the public and decision makers with a
range of possible alternatives. The CEQA Guidelines state that an EIR must describe a reasonable
range of alternatives that would avoid or substantially lessen any significant effects of the project,
but need not consider every conceivable alternative. The CEQA Guidelines further state that “the
discussion of alternatives shall focus on alternatives to the project or its location [that] are capable
of avoiding or substantially lessening any significant effects of the project, even if these
alternatives would impede to some degree the attainment of the project objectives, or would be
more costly” (CEQA Guidelines, Section 15126.6[b]). Therefore, an EIR must describe a range of
reasonable alternatives to a proposed project (or to its location) that could feasibly attain most of
the basic objectives of the project. The feasibility of an alternative may be determined based on a
variety of factors, including, but not limited to, site suitability, economic viability, availability of
infrastructure, general plan consistency, other plans or regulatory limitations, jurisdictional
boundaries, and site accessibility and control (CEQA Guidelines, Section 15126.6[f][1]).
Alternatives in an EIR must be potentially feasible (CEQA Guidelines, Section 15126.6([a]).
Agency decision makers ultimately decide what is “actually feasible” (California Native Plant
Society [CNPS] v. City of Santa Cruz [2009] 177 Cal. App. 4th 957, 981). Under CEQA, “feasible”
is defined as capable of being accomplished in a successful manner within a reasonable period of
time, taking into account economic, environmental, legal, social, and technological factors (CEQA
Guidelines Section 15364). The concept of “feasibility” also encompasses the question of whether
a particular alternative or mitigation measure promotes the underlying goals and objectives of a
project (Sierra Club v. County of Napa [2004] 121 Cal.App.4th 1490, 1506-1509; CNPS, supra,
177 Cal. App. 4th at p. 1001; In re Bay-Delta Programmatic Environmental Impact Report
Coordinated Proceedings [2008] 43 Cal.4th 1143, 1165, 1166). Moreover, “‘feasibility’ under
CEQA encompasses ‘desirability’ to the extent that desirability is based on a reasonable balancing
of the relevant economic, environmental, social, legal, and technological factors” (City of Del Mar
v. City of San Diego [1982] 133 Cal.App.3d 410, 417).

An EIR need not evaluate the environmental effects of alternatives in the same level of detail as the
proposed project, but must include enough information to allow meaningful evaluation, analysis, and
comparison with the proposed project. The alternatives discussion is intended to focus on alternatives
to the proposed project or its location that are capable of avoiding or substantially lessening any
significant effects of the project, even if these alternatives would impede, to some degree, the
attainment of the project objectives (see Section 4.1.1, Project Objectives).
The lead agency’s decision-making body, in this case the Contra Costa County Board of
Supervisors, has the discretion to select a project alternative in lieu of the proposed project. If this
were to occur, the County Board of Supervisors would need to ensure that the level of detail
included in the alternatives analysis is adequate and that there would not be any new or significant
impacts as a result of selecting the alternative. The required Findings of Fact and Mitigation
Monitoring and Reporting Plan would need to be prepared that identifies the alternative as the
project selected for approval. It is anticipated that if one of the project alternatives is selected, the
mitigation measures identified for the proposed project would not change and would still be
required; depending on the alternative selected, that alternative may require additional mitigation
measures where impacts are more severe than the proposed project.
This chapter identifies the project objectives, describes the project alternatives, and evaluates the
comparative effects of the alternatives relative to the proposed project. As required under Section
15126.6(e) of the CEQA Guidelines, the environmentally superior alternative is identified and
included at the end of this chapter.
4.1.1 Project Objectives
Pursuant to CEQA Guidelines, Section 15126.6(a), an alternative should feasibly attain most of
the basic objectives of the project. The project objectives are stated in Section 2.3, Project
Objectives, and repeated below:
• Develop airport facilities to support the types of development envisioned in the Airport
Master Plan and subsequent airport planning efforts.
• Achieve economic self-sufficiency of the airport through the development of airport-
related land uses.
• Protect current and future airport operations from incompatible land uses.
• Provide a streamlined planning framework for development consistent with the General
Plan and the Airport Land Use Compatibility Plan (ALUCP).

4.1.2 Alternatives Considered but Dismissed from
Further Consideration
CEQA Guidelines Section 15126.6(c) requires an EIR to identify and briefly discuss any
alternatives that were considered by the lead agency but were rejected as infeasible during the
scoping process. Alternatives that would have the same or greater impacts as the proposed project,
that would not meet most of the project objectives, or that were otherwise infeasible were
dismissed from further consideration. This alternative considered but rejected is described below.
Off-Site Alternative
CEQA Guidelines Section 15126.6(f)(2) states than an EIR should consider whether any of the
significant effects of a proposed project would be avoided or substantially reduced by putting the
project in another location. In addition, the lead agency must determine the feasibility of an off-
site alternative.
Where a project is consistent with an approved General Plan, consideration of an off-site
alternative is not required, per Citizens of Goleta Valley v. Board of Supervisors (1990) 52 Cal.3d
553 (Goleta II). The EIR “is not ordinarily an occasion for the reconsideration or overhaul of
fundamental land-use policy” (Goleta II, supra, 52 Cal.3d at p. 573). In approving a General Plan,
the local agency has already identified and analyzed suitable alternative sites for particular types
of development and has selected a feasible land use plan. “Informed and enlightened regional
planning does not demand a project EIR dedicated to defining alternative sites without regard to
feasibility. Such ad hoc reconsideration of basic planning policy is not only unnecessary, but would
be in contravention of the legislative goal of long-term, comprehensive planning” (Goleta II,
supra, 52 Cal.3d at pp. 572–573).
There are two airport locations identified in the Contra Costa General Plan: Buchanan Field Airport
and Byron Airport. No other airport locations are considered. It is a basic objective of the proposed
project to locate development on airport property that would economically benefit the airport and create
economic self-sufficiency. The types of development envisioned at the project site would benefit from
the proximity of the airport. Furthermore, the Contra Costa County General Plan prohibits industrial
and commercial development adjacent to airports to prevent future land conflicts from restricting the
operations of the airport (Contra Costa County 2005a). Therefore, off-site development would not meet
a basic project objective. Furthermore, additional development at Buchanan Field Airport would not
meet the project objectives. Buchanan Field Airport is located adjacent to an urban area, the City of
Concord, and has a higher level of development on and around the airport. This development supports
Buchanan Field Airport economically. Additional development there would only widen the disparity
between the two airports in terms of supportive development.

4.2 ALTERNATIVES CONSIDERED
This section provides a description of the alternatives to the proposed proje ct analyzed in this
Draft Final EIR, and evaluates how specific impacts differ in severity from those associated
with the proposed project.
The alternatives to the proposed project analyzed in this Draft Final EIR are as follows:
Alternative 1: No Project/Aviation Only
Alternative 2: Aviation Expansion
Alternative 3: Reduced Intensity
4.2.1 Alternative 1: No Project/Aviation Only
Basis for Consideration
An EIR alternatives analysis must include the “no project” alternative to allow decision makers to
compare the impacts of approving the proposed project with the impacts of not approving the
proposed project (CEQA Guidelines Section 15126.6[e][1]). The no project discussion follows
one of two lines of analysis: (1) where the project includes a change to a land use plan or policy
(including zoning), what kind of development would reasonably be expected to occur under
existing plans and considering available infrastructure and services, or (2) if no development
would occur (the “no build” alternative), what would the effects be of the project site remaining in
its existing state compared to the circumstances if the proposed project were approved.
The approved Byron Airport Master Plan and Airport Layout Plan (Appendix D to the Airport
Master Plan) identify additional aviation development to support the anticipated growth in airport
operations. These include aircraft storage, cargo facilities, maintenance and repair, corporate
hangars and fixed-base operators, and expanded pilot and passenger facilities (Contra Costa
County 2005b, 2016). Aviation uses are consistent with the existing P-1 zoning and the ALUCP
for Byron Airport, and were evaluated in the 1985 EIR prepared for the siting and development of
Byron Airport. Therefore, some level of development should be considered in the “no project”
scenario, consistent with the CEQA Guidelines. However, existing infrastructure is inadequate to
serve even the build-out of the current master planned aviation uses. It is, therefore, assumed that
aircraft storage could accommodate the additional 62 based aircraft. Supporting facilities would
be limited to 20,000 to 40,000 square feet—the estimated amount of development that could be
supported by the septic system based on existing use and capacity (Mead & Hunt 2013).
4 – ALTERNATIVES
Byron Airport Development Program EIR 9269
February 2022 4-5
Description
It is assumed that based aircraft and operations would increase, consistent with the Airport Master
Plan. This alternative assumes that 167 aircraft would be based at the airport within 10 years
(compared to the current estimate of 105). Airport storage, including hangars and tie-downs, would
be constructed to accommodate additional aircraft. New structures would be limited to 20,000 to
40,000 square feet due to limitations in water, sewer, and stormwater infrastructure. Development
would occur in the aviation area, adjacent to existing airport facilities, as identified in Chapter 2,
Project Description. No development would occur in the non-aviation area east of the main
runway. Acquisition of the residence in the northeast corner of the project site would not occur.
Comparative Analysis of Environmental Effects
The No Project/Aviation Only Alternative would avoid all significant and unavoidable impacts
associated with the proposed project (see Table 4-1). This alternative would include some
construction activities and additional facilities, so certain construction-related impacts would be
potentially significant, but these would be mitigated through implementation of feasible mitigation
measures identified for that project. These measures would be for impacts to biology, cultural
resources, geology, hazards, and hydrology.
Relationship to Proposed Project Objectives
The No Project/Aviation Only Alternative would, for the most part, achieve the aviation-related
objectives of the project, as follows:
• Develop airport facilities to support the types of development envisioned in the Airport
Master Plan and subsequent airport planning efforts.
• Protect current and future airport operations from incompatible land uses.
This alternative would not achieve the objectives related to economic development or financial
self-sufficiency.
4.2.2 Alternative 2: Aviation Expansion
Basis for Consideration
The Aviation Expansion Alternative is similar to the No Project/Aviation Only Alternative (see
above), but assumes that additional infrastructure would be constructed for full build-out of the
aviation area. This alternative would reduce significant impacts related to transportation and related
health risks, greenhouse gas emissions, and noise. Since traffic generation from new development
east of the main runway (including vendors, employees, and visitors) would not occur, this
alternative is expected to substantially reduce those impacts.
4 – ALTERNATIVES
Byron Airport Development Program EIR 9269
February 2022 4-6
Description
It is assumed that based aircraft and operations would increase consistent with the Airport Master
Plan. A total of 11.8 acres would be dedicated to future airport storage (including hangars and tie-
downs). Up to 154,000 square feet of aviation-related buildings would be constructed within an
area of 11.8 acres. No development would occur in the airport-related area east of the main runway.
Acquisition of the residence in the northeast corner of the project site would not occur.
Comparative Analysis of Environmental Effects
Since no development would occur east of the main runway, the three houses near the airport
would not be affected, avoiding impacts related to health risk and noise (due to increased traffic).
Transportation impacts would be substantially reduced (because of reduced number of truck
traffic, vendors, employees, and visitors). The potentially significant (but mitigatable) aesthetics
impact of large structures east of the airport would also be avoided. Associated greenhouse gas
emissions would also be substantially reduced. Construction impacts related to expansion of the
aviation uses, including impacts to biology, cultural resources, geology, hazards, hydrology, and
public utilities, would still occur, but would be mitigated by feasible mitigation measures, as
described throughout this EIR.
Relationship to Proposed Project Objectives
The Aviation Expansion Alternative would achieve the aviation-related objectives of the project,
as follows:
• Develop airport facilities to support the types of development envisioned in the Airport
Master Plan and subsequent airport planning efforts.
• Protect current and future airport operations from incompatible land uses.
This alternative would not achieve the objectives related to economic development or financial
self-sufficiency.
4.2.3 Alternative 3: Reduced Intensity
Basis for Consideration
The Reduced Intensity Alternative is based on the initial development scenario for the proposed
project. This scenario did not include an update of the ALUCP, so the intensity of proposed
development was constrained. Since several of the significant project impacts are related to the
intensity of development, particularly in proximity to residential uses east of the airport, this reduced-
intensity alternative provides a useful comparison. This alternative would use the same development
footprint as the proposed project, but would not include acquisition of the 11.7-acre parcel. Due to the
4 – ALTERNATIVES
Byron Airport Development Program EIR 9269
February 2022 4-7
reduced amount of acreage, potential office and commercial uses would be eliminated from the
development scenario, and that acreage would be added to the warehousing uses.
Description
Based aircraft and operations would increase consistent with the Airport Master Plan because
aviation expansion would still occur on the 23.5 acres designated for aviation uses. The
development footprint would be similar to the proposed project, but the intensity would be
reduced. The floor-to-area ratio of logistics/warehouse/distribution would be reduced to 0.25 (from
0.30 for the proposed project). Office and commercial development would be eliminated, and the
potential acreage for those uses would be used for logistics/warehouse/distribution. The 11.7-acre
parcel adjacent to the airport-related development would not be acquired. The development
scenario is shown in Table 4-1, Reduced Intensity Alternative.

TOTAL 58 — 723 — 636 —
FAR = floor-to-area ratio; KSF = thousand square feet
Total building area would be reduced to 723,000 square feet, as opposed to the proposed project
amount of 941,000 square feet. Total employees and visitors would not exceed 636 at any given
time, as opposed to 1,528 for the proposed project.
Comparative Analysis of Environmental Effects
Transportation impacts would be reduced by eliminating commercial and office uses. However,
truck traffic would be similar to the proposed project, since this alternative could result in 484,000
square feet of warehouse/light industrial uses compared to 487,000 for the proposed project. Traffic
impacts would still likely be significant but reduced, with a corresponding decrease in the amount of
mitigation required. Associated greenhouse gas emissions would also be reduced, but likely not to a

less-than-significant level. Since warehousing and light industrial uses would still be constructed
east of the airport, impacts related to health risk would still potentially occur, but could be mitigated.
The potentially significant (but mitigatable) aesthetics impact of large structures east of the airport
would also be avoided, since warehousing would be less dense and farther from existing homes.
Construction impacts related to expansion of the aviation uses, including impacts to biology, cultural
resources, geology, hazards, hydrology, and public utilities, would still occur, but would be mitigated
by feasible mitigation measures described throughout this EIR.
Relationship to Proposed Project Objectives
The Reduced Intensity Alternative would achieve the avi ation-related objectives of the
project , as follows :
• Develop airport facilities to support the types of development envisioned in the Airport
Master Plan and subsequent airport planning efforts.
• Protect current and future airport operations from incompatible land uses.
This alternative would not fully achieve the economic objectives:
• Achieve economic self-sufficiency of the airport through the development of airport-
related land uses.
• Provide a streamlined planning framework for development consistent with the General
Plan and the ALUCP.

4.4 ENVIRONMENTALLY SUPERIOR ALTERNATIVE
CEQA Guidelines require that an EIR identify the environmentally superior alternative (Section
15126.6 [e][2]). If the environmentally superior alternative is the No Project Alternative, the EIR
must identify an environmentally superior alternative from among the other alternatives. As shown
in Table 4-2, the No Project Alternative is the environmentally superior alternative, so the Aviation
Expansion Alternative is considered the environmentally superior alternative per CEQA. The lead
agency must still consider the ability of the environmentally superior alternative to achieve the
project objectives.

CHAPTER 5
OTHER CEQA CONSIDERATIONS
5.1 EFFECTS FOUND NOT TO BE SIGNIFICANT
Section 15128 of the California Environmental Quality Act (CEQA) Guidelines requires that an
Environmental Impact Report (EIR) briefly describe potential environmental effects that were
determined not to be significant and therefore were not discussed in detail in the EIR. The
following environmental issues are not considered potentially significant for the reasons discussed.
5.1.1 Agriculture and Forestry Resources
The following environmental issues to agricultural and forestry resources, per Appendix G of the
CEQA Guidelines, were considered but were determined to have no potential for significant effects
related to the proposed Byron Airport Development Program (project) for the reasons stated below.
a) Would the project 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?
Per the California Department of Conservation Farmland Mapping and Monitoring Program, the
project site, including the airport property and the acquisition parcel, are classified as grazing land,
farmland of local importance, and urban (FMMP 2016). Therefore, there is are no lands that would
be affected by the project that meet the definition of important farmland under CEQA.
b) Would the project conflict with existing zoning for agricultural use, or a
Williamson Act contract?
The airport property is zoned P-1, Planned Development (Contra Costa County 2005). The P-1
zone does allow for agricultural uses, but is not an exclusive agricultural zoning under the Contra
Costa County Zoning Ordinance. In addition, no active farming operations are present on the
airport property.
The acquisition parcel is zoned A-3, Heavy Agriculture. However, land use of the parcel is a
single-family home and is not actively used for agriculture.
There are no Williamson Act contracts on the project site. There are two contracts, No. 21-73 and
No. 4-78, east of Byron Airport. These contracted lands would not be affected by project
construction or operation.
5 – OTHER CEQA CONSIDERATIONS
Byron Airport Development Program EIR 9269
February 2022 5-2
c) Would the project 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))?
There are no timberland zoning districts on or adjacent to the project site, and there are no forest
land resources on the project site.
d) Would the project result in the loss of forest land or conversion of forest land to non-
forest use?
The project site and project vicinity do not contain forest lands.
e) Would the project involve other changes in the existing environment which, due to their
location or nature, could result in conversion of Farmland, to non-agricultural use or
conversion of forest land to non-forest use?
The proposed project is the expansion of aviation uses and the development of airport-related
commercial and industrial land uses. The project would not introduce residences or other sensitive
land uses that could create conflicts with agricultural operations. Agriculture is generally
considered a compatible use with a public-use airport.
5.2 SIGNIFICANT AND UNAVOIDABLE ENVIRONMENTAL IMPACTS
Section 15126.2(b) of the CEQA Guidelines requires that an EIR describe any significant impacts
that cannot be avoided, even with implementation of feasible mitigation measures. The
environmental impacts of the proposed project, including significant and unavoidable impacts, are
discussed in the technical sections contained in Chapter 3, Environmental Setting and Impacts, of
this EIR. Significant and unavoidable impacts are also listed below:
Impact 3.2-1. The project would conflict with or obstruct implementation of the
applicable air quality plan.
Impact 3.2-2. The project would result in a cumulatively considerable net increase of
criteria pollutants for which the project region is in nonattainment under
an applicable Federal or State ambient air quality standard.
Impact 3.6-1. The project would generate greenhouse gas emissions, either directly or
indirectly, that may have a significant impact on the environment.
Impact 3.6-2. The project would conflict with an applicable plan, poli cy, or regulation
adopted for the purpose of reducing the emissions of greenhouse gases.
5 – OTHER CEQA CONSIDERATIONS
Byron Airport Development Program EIR 9269
February 2022 5-3
Impact 3.10-1. The project would result in exposure of persons to or generation of noise
levels in excess of standards established in the local general plan or noise
ordinance, or applicable standards of other agencies.
Impact 3.13-1. The project would conflict with an applicable plan, ordinance or policy
establishing measures of effectiveness for the performance or the
circulation system.
5.3 SIGNIFICANT IRREVERSIBLE ENVIRONMENTAL IMPACTS
Section 15126.2(c) of the CEQA Guidelines requires a discussion of any significant irreversible
environmental change that would be caused by a proposed project. Generally, a project would
result in significant irreversible changes if:
• The primary and secondary impacts would generally commit future generations to similar
uses (such as highway improvement that provides access to a previously inaccessible area);
• The project would involve a large commitment of nonrenewable resources (CEQA
Guidelines Section 15126.2[c]);
• The primary and secondary impacts would generally commit future generations to similar uses;
• The project would involve uses in which irreversible damage could result from any
potential environmental accidents associated with the project;
• The project would involve a large commitment of nonrenewable resources; or
• The proposed consumption of resources is not justified (e.g., the project involves the
wasteful use of energy).
Implementation of the proposed project would result in the long-term commitment of resources of
the project site to the operation of Byron Airport and supportive development. The location of
Byron Airport was selected to minimize land use impacts and to provide on-site mitigation for
biological resources affected by development of the airport.
Ongoing resource use by the project would include water, electricity, natural gas, and fossil fuels.
With respect to operational activities, compliance with all applicable state and local building codes,
as well as mitigation measures described in the EIR, would ensure that resources are conserved to
the maximum extent possible. Energy usage and conservation related to the project are discussed
in Section 3.15, Energy Consumption.
The CEQA Guidelines also require a discussion of the potential for irreversible environmental
damage caused by environmental accidents associated with a project. Although the project would
result in the use, transport, storage, and disposal of minor amounts of hazardous materials during
5 – OTHER CEQA CONSIDERATIONS
Byron Airport Development Program EIR 9269
February 2022 5-4
project construction and operation, as described Section 3.7, Hazards and Hazardous Materials, all
such activities would comply with applicable local, state, and federal laws related to the use,
storage, and transport hazardous materials, which would significantly reduce the likelihood and
severity of accidents that could result in irreversible environmental damage. The project itself does
not propose any uniquely hazardous uses that would require any special handling or storage.
5.4 GROWTH-INDUCING IMPACTS
As required by Section 15126.2(d) of the CEQA Guidelines, an EIR must discuss ways in which
a proposed project could foster economic or population growth or the construction of additional
housing, either directly or indirectly, in the surrounding environment.
The proposed project would involve activities at Byron Airport consistent with the Airport Master
Plan, which would foster planned economic growth. Aviation uses would be expanded to
accommodate the growth in airport operations and planned growth consistent with Federal
Aviation Administration forecasts. Development of airport-related commercial and industrial uses
would support economic self-sufficiency at the airport while promoting a jobs/housing balance in
eastern Contra Costa County. The environmental effects of economic growth (project activities)
are discussed within this EIR.
The potential for population growth or housing construction is discussed in Section 3.11,
Population, Housing, and Growth, which concludes that the proposed project would not result in
unplanned population or housing growth.

Project Title: Byron Airport Development Program
Public Resources Code (PRC) § 3208.1 establishes well reabandonment responsibility when a
previously plugged and abandoned well will be impacted by planned property development or
construction activities. Local permitting agencies, property owners, and/or developers should be aware
of, and fully understand, that significant and potentially dangerous issues may be associated with
development near oil, gas, and geothermal wells.
The California Geologic Energy Mangagement Division (CalGEM) has received and reviewed the above
referenced project dated 8/2/2021. To assist local permitting agencies, property owners, and developers
in making wise land use decisions regarding potential development near oil, gas, or geothermal wells,
the Division provides the following well evaluation.
The project is located in Contra Costa County, within the boundaries of the following fields:
Any Field
Our records indicate there are 3 known oil or gas wells located within the project boundary as identified
in the application.

• Number of wells Not Abandoned to Current Division Requirements as Prescribed by Law and
Projected to Be Built Over or Have Future Access Impeded by this project: 0
• Number of wells Not Abandoned to Current Division Requirements as Prescribed by Law and
Not Projected to Be Built Over or Have Future Access Impeded by this project: 3
• Number of wells Abandoned to Current Division Requirements as Prescribed by Law and
Projected to Be Built Over or Have Future Access Impeded by this project: 0
• Number of wells Abandoned to Current Division Requirements as Prescribed by Law and Not
Projected to Be Built Over or Have Future Access Impeded by this project: 0
The Division categorically advices against building over, or in any way impeding access to, oil, gas, or
geothermal wells. Impeding access to a well could result in the need to remove any structure or
obstacle that prevents or impedes access including, but not limited to, buildings, housing, fencing,
landscaping, trees, pools, patios, sidewalks, roadways, and decking. Maintaining sufficient access is
considered the ability for a well servicing unit and associated necessary equipment to reach a well from
a public street or access way, solely over the parcel on which the well is located. A well servicing unit,
and any necessary equipment, should be able to pass unimpeded along and over the route, and should
be able to access the well without disturbing the integrity of surrounding infrastructure.
There are no guarantees a well abandoned in compliance with current Division requirements as
prescribed by law will not start leaking in the future. It always remains a possibility that any well may
start to leak oil, gas, and/or water after abandonment, no matter how thoroughly the well was plugged
and abandoned. The Division acknowledges wells plugged and abandoned to the most current Division
requirements as prescribed by law have a lower probability of leaking in the future, however there is no
guarantees that such abandonments will not leak.
The Division advises that all wells identified on the development parcel prior to, or during, development
activities be tested for liquid and gas leakage. Surveyed locations should be provided to the Division in
Latitude and Longitude, NAD 83 decimal format. The Division expects any wells found leaking to be
reported to it immediately.
Failure to plug and reabandon the well may result in enforcement action, including an order to perform
reabandonment well work, pursuant to PRC § 3208.1, and 3224.
PRC § 3208.1 give the Division the authority to order or permit the re-abandonment of any well where it
has reason to question the integrity of the previous abandonment, or if the well is not accessible or
visible. Responsibility for re-abandonment costs may be affected by the choices made by the local
Page 2

permitting agency, property owner, and/or developer in considering the general advice set forth in this
letter. The PRC continues to define the person or entity responsible for reabandonment as:
1. The property owner - If the well was plugged and abandoned in conformance with Division
requirements at the time of abandonment, and in its current condition does not pose an immediate
danger to life, health, and property, but requires additional work solely because the owner of the
property on which the well is located proposes construction on the property that would prevent or
impede access to the well for purposes of remedying a currently perceived future problem, then the
owner of the property on which the well is located shall obtain all rights necessary to reabandon the
well and be responsible for the reabandonment.
2. The person or entity causing construction over or near the well - If the well was plugged and
abandoned in conformance with Division requirements at the time of plugging and abandonment,
and the property owner, developer, or local agency permitting the construction failed either to obtain
an opinion from the supervisor or district deputy as to whether the previously abandoned well is
required to be reabandoned, or to follow the advice of the supervisor or district deputy not to
undertake the construction, then the person or entity causing the construction over or near the well
shall obtain all rights necessary to reabandon the well and be responsible for the reabandonment.
3. The party or parties responsible for disturbing the integrity of the abandonment - If the well was
plugged and abandoned in conformance with Division requirements at the time of plugging and
abandonment, and after that time someone other than the operator or an affiliate of the operator
disturbed the integrity of the abandonment in the course of developing the property, then the party
or parties responsible for disturbing the integrity of the abandonment shall be responsible for the
reabandonment.
No well work may be performed on any oil, gas, or geothermal well without written approval from the
Division. Well work requiring approval includes, but is not limited to, mitigating leaking gas or other
fluids from abandoned wells, modifications to well casings, and/or any other re-abandonment work. The
Division also regulates the top of a plugged and abandoned well's minimum and maximum depth below
final grade. CCR §1723.5 states well casings shall be cut off at least 5 feet but no more than 10 feet
below grade. If any well needs to be lowered or raised (i.e. casing cut down or casing riser added) to
meet this regulation, a permit from the Division is required before work can start.
The Division makes the following additional recommendations to the local permitting agency, property
owner, and developer:
1. To ensure that present and future property owners are aware of (a) the existence of all wells
located on the property, and (b) potentially significant issues associated with any improvements
Page 3

near oil or gas wells, the Division recommends that information regarding the above identified
well(s), and any other pertinent information obtained after the issuance of this letter, be
communicated to the appropriate county recorder for inclusion in the title information of the subject
real property.
2. The Division recommends that any soil containing hydrocarbons be disposed of in accordance
with local, state, and federal laws. Please notify the appropriate authorities if soil containing
significant amounts of hydrocarbons is discovered during development.
As indicated in PRC § 3106, the Division has statutory authority over the drilling, operation,
maintenance, and abandonment of oil, gas, and geothermal wells, and attendant facilities, to prevent,
as far as possible, damage to life, health, property, and natural resources; damage to underground oil,
gas, and geothermal deposits; and damage to underground and surface waters suitable for irrigation or
domestic purposes. In addition to the Division's authority to order work on wells pursuant to PRC §§
3208.1 and 3224, it has authority to issue civil and criminal penalties under PRC §§ 3236, 3236.5, and
3359 for violations within the Division's jurisdictional authority. The Division does not regulate grading,
excavations, or other land use issues.
If during development activities, any wells are encountered that were not part of this review, the
property owner is expected to immediately notify the Division's construction site well review engineer in
the Northern district office, and file for Division review an amended site plan with well casing diagrams.
The District office will send a follow-up well evaluation letter to the property owner and local permitting
agency.
Should you have any questions, please contact me at (661) 334-3665 or via email at

LETTER P1
COMMENTER: California Department of Conservation, Geologic Energy Management Division
DATE: August 2, 2021
Response P1-1
The comment is acknowledged.
Response P1-2
The three wells described in the attachment to the comment letter are designated as Hannum Trust 1,
Hannum Trust 2, and ROCO-Hannum Trust 2. The wells are located in the Habitat Management lands
within the Airport property and, as acknowledged in the comment letter, would not be affected by the
proposed project. This information has been added to Section 3.7.1, Existing Conditions, of the Hazards
chapter of the Final EIR.
Response P1-3
The wells are located in the Habitat Management lands within the Airport property. No development will
occur over the wells, nor will access be impeded in any way as a result of this project.
Response P1-4
The comment is acknowledged.
Response P1-5
As discussed in Section 3.7, there are three abandoned oil and gas wells located within the Airport
Boundary, near Byron Hot Springs Road. These wells are located within the proposed Habitat
Management Area; development is not anticipated or proposed within this area. The closest well to a
proposed development area is approximately 0.4 miles to the southeast; the other two wells are
approximately 0.5 miles southeast of the development area. While not anticipated, should future
construction or airport development disturb or otherwise impact these wells, reabandonment would be
required in accordance with Public Resources Code (PRC) Section 3208.1. As defined in PRC 3208.1,
either the property owner or the party building over or otherwise disturbing the integrity of the abandoned
well would be responsible for the reabandonment. Compliance with applicable rules and regulations
would avoid any potentially significant impacts related to existing oil and gas wells.
This information has been added to the analysis in Impact 3.7-2 of the Final EIR.

Re: Byron Airport Development Program, County File Numbers: GP12-0003, DP14-3008, State Clearinghouse
Number: 2017092059
Mr. Barrios,
The Contra Costa Water District (District) appreciates the opportunity to comment on the Byron Airport
Development Program EIR (EIR) dated June 2021. The project is located in southeastern Contra Costa County,
south of Byron Hot Springs, west of the Clifton Court Forebay, north of the Harvey O. Banks Pumping Plan and
east of Armstrong Road.
The District is submitting comments in relation to the Phase 2 Los Vaqueros Reservoir Expansion (Phase 2
Expansion), a project of state-wide importance. The Phase 2 Expansion is a collaborative regional project that
will improve Bay Area water supply reliability and water quality while protecting Delta fisheries. The Phase 2
Expansion will also provide additional Delta ecosystem benefits as well as be able to deliver water to wildlife
refuges through its regional intertie (Transfer-Bethany Pipeline).
The EIR states on page 3-2, Cumulative Context, that “There are no currently proposed projects in the
immediate project vicinity” and for this reason the County relied on the project method from adopted plans
for its cumulative effect’s analysis. However, the District is in the permitting phase of the Phase 2 Expansion
which will increase the capacity of the existing 160-thousand acre foot (TAF) Los Vaqueros Reservoir to 275
TAF and, among other conveyance facilities, will construct the Transfer-Bethany Pipeline, an approximately
8.0 mile pipeline from the existing Transfer Facility, traversing the Byron Airport Property in the vicinity of
Armstrong Road, and continuing south to terminate at the California Aqueduct. Accordingly, the District
request that the Phase 2 Expansion, specifically the Transfer-Bethany Pipeline, be included in the cumulative
context and effects analysis of the EIR (i.e., construction, operation and maintenance effects of the Transfer-
Bethany Pipeline in the vicinity of the Byron Airport for resources areas where a cumulative condition is
reasonably foreseeable).
On background, the U.S. Department of the Interior, Bureau of Reclamation, California – Great Basin Region
(Reclamation) as the lead agency under the National Environmental Policy Act (NEPA) and the District as the
lead agency under California Environmental Quality Act (CEQA) previously released a joint Draft EIS/EIR in
Letter P2

February 2009. The Draft EIS/EIR included analysis of four action alternatives: two that include a reservoir
expansion to 275 TAF and a Transfer-Bethany Pipeline that traversed along Armstrong Road. Multiple County
departments including the Department of Conservation and Development, Flood Control and Water
Conservation District, and Public Works Department provided comments on the Draft EIS/EIR. The Final
EIS/EIR (certified March 31, 2010), was later modified by the August 2013 EIR Addendum #1 (together, the Final
EIS/EIR). The Final EIS/EIR analyzed, among other alternatives, a Timing Variant under which Los Vaqueros
Reservoir would be expanded first to 160 TAF (Phase 1 Expansion) and later to 275 TAF (Phase 2 Expansion).
Ultimately, the Phase 1 Expansion, which did not include the Transfer-Bethany Pipeline, was approved and
completed in 2012.
On June 29, 2017, Reclamation and the District published the Draft Supplement to the Final EIS/EIR which
disclosed that the Transfer-Bethany Pipeline would start at the same place on the north end and travel along
the same alignment as proposed in the Final EIS/EIR for the first 7.1 miles to an area south of the Byron
Airport. Beyond the 7.1-mile marker, the Transfer-Bethany Pipeline was modified, consistent with the
Reclamation 2016 Value Planning Study, to fully avoid tunneling and terminate at the California Aqueduct
rather than the Bethany Reservoir. The County Flood Control and Water Conservation District commented on
the document. On March 8, 2018, in response to concern raised about the Transfer-Bethany Pipeline, the
District and Reclamation held a meeting with the Department of Conservation and Development, Department
of Public Works and Airports division.
On February 28, 2020, Reclamation and the District published the Final Supplement to the Final EIS/EIR. On
May 13, 2020, the Final Supplement to the Final EIS/EIR was certified and the Phase 2 Expansion, including the
Transfer-Bethany Pipeline, was adopted by the District’ Board (Resolution-No-20-006-PDF (ccwater.com).
Reclamation plans to execute it’s Record of Decision in early 2022. All environmental documents related to
the Los Vaqueros Reservoir Expansion Project are available here: Environmental Documents | Contra Costa
Water District, CA (ccwater.com).
Thank you for your consideration of District comments to include the Phase 2 Expansion in the cumulative
context and effects analysis. The District looks forward to continued coordination with the various
department at the County on the Transfer-Bethany Pipeline. If you have any questions about this letter or the
Phase 2 Expansion please do not hesitate to contact me.
Respectfully,
Jennifer Johnson

COMMENTER: Contra Costa Water District
DATE: August 27, 2021
Response P2-1
The comment is acknowledged.
Response P2-2
The Phase 2 Los Vaqueros Reservoir Expansion, specifically the Transfer-Bethany Pipeline, has been
added to Section 3.0.2, Cumulative Setting, of the Final EIR. The Transfer-Bethany Pipeline involves the
construction of an approximately 8-mile pipeline that connects the Los Vaqueros Transfer Facility (located
between Camino Diablo and Vasco Road, northeast of the Los Vaqueros Reservoir) to the California
Aqueduct (north of Bethany Reservoir). The proposed alignment is identified in the 2020 Final
Supplement to the EIS/EIR for the Los Vaqueros Expansion Project. Th e proposed alignment would
parallel Vasco Road and follow Armstrong Road along the west edge of Byron Airport, past the southerly
property line of the Airport, before turning east and then south to connect to the California Aqueduct.
While the alignment is adjacent to, and may encroach on, Airport property, the proposed alignment is not
located near the proposed development area on Byron Airport, and would not overlap or conflict with any
offsite improvements included in the proposed project. Construction impacts for the proposed Transfer-
Bethany Pipeline, as discussed in the Los Vaqueros Expansion Project EIS/EIR, would be similar to those
associated with construction of the proposed project, including short-term air emissions, potential
disturbance of biological resources, soil erosion, hazardous materials, water quality impacts, and
temporary disruptions of utilities or traffic. The construction impacts of the Transfer-Bethany Pipeline
and the proposed project would not occur within the same project site (although, as discussed below,
would occur within the same cumulative setting) and construction schedules are unlikely to substantially
overlap (the pipeline is scheduled to be constructed in 2022 or 2023, while the Airport Development
Program would be developed over several years in response to market demand and growth in aviation
traffic). The Los Vaqueros Expansion Project EIS/EIR did not find that construction of the pipeline would
contribute to a cumulative impact. While the Byron Airport Development Program Draft EIR did not
identify the Transfer-Bethany Pipeline, it does assume a certain amount of regional growth, and
considered the cumulative effects of such growth. Based on the above factors, the construction of the
Transfer-Bethany Pipeline would not result in a new, or a substantial increase in a previously identified,
cumulative impact.

RE: Comments on the Draft Environmental Impact Report for the Byron
Airport Development Program, SCH# 2017092059
Dear Daniel Barrios:
Thank you for the opportunity to review and comment on the Byron Airport
Development Program Draft Environmental Impact Report (Draft EIR) prepared by
the Contra Costa County Department of Conservation and Development (DCD). The
Delta Stewardship Council (Council) recognizes the objectives of the Byron Airport
Development Program (project), as described in the Draft EIR: Contra Costa County
intends to amend its Airport Land Use Compatibility Plan (ALUCP), Contra Costa
County General Plan (General Plan), and Planned Unit District zoning to
substantially broaden the range of uses allowed “by-right” on airport property. Of
interest to the Council are areas located outside of the 2006 voter-approved urban
limit line, including portions of the new safety/compatibility zones, specifically, B1
and B3 (new Safety Zone 2), and B2 (new Safety Zone 3).
The Council is an independent state agency established by the Sacramento-San
Joaquin Delta Reform Act of 2009, codified in Division 35 of the California Water
Letter P3
1
Contra Costa County, Department of Conservation and Development
Attn: Daniel Barrios
August 30, 2021
Page 2
Code, sections 85000-85350 (Delta Reform Act). The Delta Reform Act charges the
Council with furthering California’s coequal goals of providing a more reliable water
supply and protecting, restoring, and enhancing the Sacramento-San Joaquin River
Delta (Delta) ecosystem. (Water Code, § 85054.) The Delta Reform Act further states
that the coequal goals are to be achieved in a manner that protects and enhances
the unique cultural, recreational, natural resource, and agricultural values of the
Delta as an evolving place. The Council is charged with furthering California’s
coequal goals for the Delta through the adoption and implementation of the Delta
Plan. (Wat. Code, § 85300.)
Pursuant to the Delta Reform Act, the Council has adopted the Delta Plan, a
comprehensive long-term management plan for the Delta and Suisun Marsh that
furthers the coequal goals. The Delta Plan contains regulatory policies, which are
set forth in California Code of Regulations, Title 23, sections 5001-5015. A state or
local agency that proposes to carry out, approve, or fund a qualifying action in
whole or in part in the Delta, called a "covered action," is required to prepare a
written certification of consistency with detailed findings as to whether the covered
action is consistent with the Delta Plan and submit that certification to the Council
prior to implementation of the covered action. (Wat. Code, § 85225.) Water Code
section 85057.5, subdivision (a), defines a covered action as a plan, program, or
project as defined pursuant to Section 21065 of the Public Resources Code that
meets all the following conditions:
1. Will occur in whole or in part within the boundaries of the legal Delta
(Water Code, §12220) or Suisun Marsh (Pub. Resources Code, §
29101). The approximate boundaries of these areas are publicly
available on the Open Data Portal at
https://data.ca.gov/dataset/legal-delta-boundary and
https://data.ca.gov/dataset/suisun-marsh-boundary. The eastern
portion of Byron Airport is located within the Delta.
2. Will be carried out, approved, or funded by the State or a local public agency.
Contra Costa County is the local public agency that will approve and carry out
the project.
3. Will have a significant impact on the achievement of one or both of the
coequal goals or the implementation of a government-sponsored flood
control program to reduce risks to people, property, and State interests in

the Delta. The project would have a significant impact on the achievement of
the coequal goal to protect, restore, and enhance the Delta ecosystem.
4. Is covered by one or more of the regulatory policies contained in the Delta
Plan (Cal. Code Regs., tit. 23, §§ 5003-5015). Delta Plan regulatory policies
that may apply to the project are discussed below.
The State or local agency approving, funding, or carrying out the project must
determine if the project is a covered action and, if so, submit a Certification of
Consistency to the Council prior to project implementation. (Wat. Code, § 85225;
Cal. Code Regs., tit. 23, § 5001(j)(3).)
COMMENTS REGARDING DELTA PLAN POLICIES AND POTENTIAL
CONSISTENCY CERTIFICATION
The following section describes the Delta Plan regulatory policies that may apply to
the proposed project based on the available information in the Draft EIR. This
information is offered to assist DCD to prepare environmental documents that
could be used to support a future Certification of Consistency for the project. This
information may also assist DCD to describe the relationship between the project
and the Delta Plan in the Final EIR.
General Policy 1: Detailed Findings to Establish Consistency with the Delta
Plan
Delta Plan Policy G P1 (Cal. Code Regs., tit. 23, § 5002) specifies what must be
addressed in a Certification of Consistency for a covered action. The following is a
subset of policy requirements which a project shall fulfill to be considered
consistent with the Delta Plan:
Mitigation Measures
Delta Plan Policy G P1(b)(2) (Cal. Code Regs., tit. 23, § 5002(b)(2)) requires
covered actions not exempt from the California Environmental Quality Act
(CEQA) must include all applicable feasible mitigation measures adopted and
incorporated into the Delta Plan as amended April 26, 2018 (unless the
measures are within the exclusive jurisdiction of an agency other than the

mitigation measures are identified in Delta Plan Appendix O and are
available at: https://deltacouncil.ca.gov/pdf/delta-plan/2018-appendix-o-
mitigation-monitoring-and-reporting-program.pdf.
The Draft EIR proposes project mitigation measures for potentially significant
impacts to aesthetics; air quality; biological resources; cultural resources;
geology, soils, and minerals; greenhouse gas emissions; hazards and
hazardous materials; hydrology and water quality; and transportation and
traffic. The mitigation measures adopted in the Final EIR must be equally or
more effective than applicable feasible Delta Plan mitigation measures. In a
future Certification of Consistency for the project, DCD should document
how the adopted mitigation measures are equally or more effective than the
applicable mitigation measures contained in Delta Plan Appendix O.
Best Available Science
Delta Plan Policy G P1(b)(3) (Cal. Code Regs., tit. 23, § 5002(b)(3)) states that
actions subject to Delta Plan regulations must document use of best
available science as relevant to the purpose and nature of the project. The
Delta Plan defines best available science as “the best scientific information
and data for informing management and policy decisions.” (Cal. Code Regs,
tit. 23, § 5001 (f).) Best available science is also required to be consistent with
the guidelines and criteria in Appendix 1A of the Delta Plan
(https://deltacouncil.ca.gov/pdf/delta-plan/2015-appendix-1a.pdf).
Delta as Place Policy 1: Locate New Urban Development Wisely
Delta Plan Policy DP P1 (Cal. Code Regs., tit. 23, § 5010) places certain limits
on new urban development within the Delta. New residential, commercial,
or industrial development must be limited to areas that city or county
general plans designate for such development as of the date of the Delta
Plan’s adoption (May 16, 2013). In Contra Costa County, new residential,
commercial, and industrial development within the Delta must be limited to
areas within the 2006 voter-approved urban limit line (ULL) (Cal. Code
Regs., tit. 23, § 5010(a)(2)). This policy is intended to strengthen existing
Delta communities while protecting farmland and open space, providing
land for ecosystem restoration needs, and reducing flood risk.

According to the Draft EIR, the General Plan designations for the Byron Airport
property are Public/Semi-Public (PS) and Open Space (OS) (Draft EIR, p. 2-6).
Although most of the Byron Airport is located within the ULL, the portion of the
Airport designated as Open Space is outside the ULL. This area is subject to Delta
Plan Policy DP P1 (Cal. Code Regs., tit. 23, § 5010). Although the Draft EIR states
that the General Plan designation for the existing airport property will not change,
ALUCP Policy 5-77 would be amended to reflect the new compatibility zone (Zone B-
1 would become Safety Zone 2) designations and additional uses at the airport that
may be found compatible under the updated ALUCP for Byron Airport (Draft EIR p.
2-6).
The project proposes acquisition of an 11.7-acre property on Armstrong Road that
is currently designated for Agricultural use and update the general plan designation
to PS (Draft EIR, p. 2-6). This proposed acquisition is located within the ULL, and is
therefore not subject to DP P1.
Based on review of the Draft EIR, the locations of the project site and the ULL, and
the existing and proposed General Plan designations, the project may be consistent
with DP P1, although DCD must identify this in a Certification of Consistency for the
project. DCD should revise the Final EIR to identify DP P1 requirements in the
regulatory setting of the Land Use and Planning section.
CLOSING COMMENTS
The Council will continue to track the Byron Airport Development Program’s
progress and invites DCD to engage in early consultation as future program
updates are considered, in order to discuss project features and mitigation
measures that would promote consistency with the Delta Plan.
More information on covered actions, early consultation, and the certification
process can be found on the Council website,
https://coveredactions.deltacouncil.ca.gov. Please contact

Byron Airport Development Program EIR 9269
February 2022 7-19
LETTER P3
COMMENTER: Delta Stewardship Council
DATE: August 30, 2021
Response P3-1
The proposed project would update the Airport Land Use Compatibility Plan (ALUCP), which currently
is not consistent with the recommendations of the most recent California Airport Land Use Planning
Handbook, published by the Department of Transportation, Division of Aeronautics, nor with similar
policies applicable to the County’s other public airport, Buchanan Field. The amendments to the General
Plan and Planned Unit District zoning would allow for a greater variety of land uses on airport property
that are consistent with the updated ALUCP. It should be noted that changes to the safety/compatibility
zones outside of the airport property, and therefore outside of the ULL, would not allow for additional
land uses not otherwise allowed by the existing agricultural zoning.
Response P3-2
The proposed project is a County-initiated General Plan Amendment (GPA), Development Plan
Modification (DPM), Rezone, and ALUCP Amendment for the Byron Airport to expand the range of uses
allowed on the airport property. The proposed GPA includes new policies that update and clarify the range
of land uses and activities allowed at Byron Airport, similar to those already adopted for the County’s
other general aviation airport, Buchanan Field in Concord, as well as a redesignation of an 11.7-acre parcel
from Agricultural Lands (AL) to Public and Semi-Public (PS). The current Development Plan for the
airport would be modified to permit all of the new uses either by-right or with approval of a land use
(conditional) permit. The DPM would also establish certain development standards, such as maximum
building heights, maximum lot coverage, landscaping requirements, etc. The rezone is requested for the
11.7-acre parcel to be acquired by the County and rezoned from Agriculture (A-3) to P-1 to be part of the
Byron Airport Development Program. The ALUCP would be updated with new policies and maps specific
to Byron Airport. The updated policies and maps would reflect the 2017 Airport Layout Plan for Byron
Airport, the 2005 Byron Airport Master Plan, and guidance set forth in the most recent version of the
Caltrans California Airport Land Use Planning Handbook. It should be noted that changes to the
safety/compatibility zones outside of the airport property are outside of the ULL and would not allow for
additional land uses not otherwise allowed by the existing agricultural zoning.
Pursuant to the definition of a “covered action,” as defined in Water Code Section 85057.5(a), the proposed
project must meet all listed criteria in order to be considered a covered action under the Delta Plan. The third
criterion in this list requires that the project “Will have a significant impact on the achievement of one of both
of the coequal goals or the implementation of a government-sponsored flood control program to reduce risks
to people, property, and State interests in the Delta.” However, the project does not meet this criterion, as it
will not have a significant impact on the achievement of the coequal goals.
7 – COMMENTS AND RESPONSES TO COMMENTS
Byron Airport Development Program EIR 9269
February 2022 7-20
The Delta Plan includes policies that are considered essential to achieving the coequal goals, and the project is
consistent with policy DP P1. Delta Plan Policy DP P1(a)(2) states, “New residential, commercial, and
industrial development must be limited to the following areas, as shown in Appendix 6 and Appendix 7…
Areas within Contra Costa County’s 2006 voter-approved urban limit line, except no new residential,
commercial, and industrial development may occur on Bethel Island unless it is consistent with the Contra
Costa County General Plan effective as of May 16, 2013.” Stated simply, projects located within Contra Costa
County’s 2006 voter-approved Urban Limit Line are not considered a covered action, as urban development
is allowed within the County ULL. Since the development that would occur as a result of the proposed project
is wholly contained within the County ULL, the proposed project is consistent with policy DP P1, which would
then result in the project supporting the achievement of the coequal goals. As it would support the achievement
of the coequal goals, the proposed project would not have a significant impact on achievement of one or both
of the coequal goals, and, therefore, the proposed project is not a covered action under the Delta Plan.
Response P3-3
As described in Response P3-2, the proposed project is not a covered action under the Delta Plan, as it is
consistent with policy DP P1 and supports the achievement of the Delta Plan’s coequal goals. As the
comments identified in this section of the comment letter pertain to a situation where the project is, in fact,
a covered action, these comments are not applicable to the proposed project.
Response P3-4
The comment is acknowledged.

unrecorded cultural resources are in the potential APE or surrounding the APE; and
▪ If a survey is recommended by the Information Center to determine whether
previously unrecorded cultural resources are present.
The Tribe requests to be present at any survey conducted on the
Applicants behalf.
2. The results of any archaeological inventory survey that was conducted, including:
▪ Any reports that may contain site forms, site significance, and suggested
mitigation measures.
▪ Any reports or inventories found under the Native American Graves Protection
and Repatriation Act.
All information regarding site locations, Native American human remains,
and associated funerary objects should be in a separate confidential
addendum, and not be made available for public disclosure in accordance with

The information gathered will provide us with a better understanding of the project and will
allow the Tribe to compare your records with our database.
We would like to remind your agency that CEQA Guidelines section 15126.4, subdivision (b)(3)
states that preservation in place is the preferred manner of mitigating impacts to archaeological
sites. Section 15126.4, subd. (b)(3) of the CEQA Guidelines has been interpreted by the
California Court of Appeal to mean that “feasible preservation in place must be adopted to
mitigate impacts to historical resources of an archaeological nature unless the lead agency
determines that another form of mitigation is available and provides superior mitigation of
impacts.” Madera Oversight Coalition v. County of Madera (2011) 199 Cal.App.4th 48,
disapproved on other grounds, Neighbors for Smart Rail v. Exposition Metro Line Construction
Authority (2013) 57 Cal.4th 439.

LETTER T1
COMMENTER: Wilton Rancheria
DATE: July 14, 2021
Response T1-1
Wilton Rancheria requests formal consultation with the County under both Senate Bill 18 and Assembly
Bill 52. The County had previously contacted Wilton Rancheria on August 15, 2017, regarding
consultation on the proposed project. A response was received from Wilton Rancheria requesting
consultation on August 25, 2017. The County responded on September 7, 2017, and February 22, 2018,
but no further communication was received until this Draft EIR comment letter dated July 14, 2021.
Based on this comment letter, the County re-entered consultation with Wilton Rancheria regarding the
proposed project on September 22, 2021. As described in the responses below, information was provided
by the County and revisions made to the EIR mitigation measures that address the discovery of previously
identified resources. Having received no further communication regarding the revised mitigation measures
as presented in this Final EIR, consultation was closed by the County on January 21, 2022.
Response T1-2
Per the request, the County has provided all available information regarding cultural resources and tribal
cultural resources within the project site to Wilton Rancheria.
Response T1-3
The County agrees that preservation in place is the preferred method of mitigation for archaeological sites
whenever feasible. To date, the analysis conducted has not identified a historic or unique archaeological
site, or a tribal cultural resource, that would be impacted by the proposed project. The County has
consulted with Wilton Rancheria on improving the mitigation measures included in the Draft EIR for the
discovery of previously identified resources. The proposed revisions are reflected in this Final EIR,
specifically mitigation measures MM-CUL-1 (procedures for construction monitoring and accidental
discovery) and newly added MM-CUL-4 (environmental awareness training for construction workers).
The revisions to the Draft EIR are shown below.
MM-CUL-1 Accidental Discovery of Archaeological Resources. Prior to commencement of any
construction activities involving ground disturbance, Contra Costa County, a qualified
archaeologist, representatives from interested Native American Tribes, and the
construction contractor shall be invited to meet or otherwise discuss by conference call the
project site’s archaeological sensitivity and determine the duration and extent of
monitoring for archaeological deposits that may be uncovered during construction. Given
the present disturbed condition in some locations surrounding existing airport facilities,
7 – COMMENTS AND RESPONSES TO COMMENTS

February 2022 7-25
areas of elevated potential for encountering unanticipated resources should be considered
those within 500 feet of the historic-era corral and Brushy Creek, and no deeper than 4 feet
below the present ground surface. An archaeological monitor and a monitor from a
culturally affiliated Native American Tribe shall be present for initial ground-disturbing
work in these areas, after which the monitoring frequency shall be reduced to periodic spot-
checks elsewhere. The monitoring strategy shall be adjusted (increased, decreased, or
discontinued) based on the results of monitoring within areas of elevat ed archaeological
sensitivity and as recommended by a qualified archaeologist meeting the Secretary of the
Interior’s Professional Qualification Standards, in consultation with culturally affiliated
Native American Tribes. In the event that archaeological resources are exposed, work
within 100 feet of the find shall be halted or directed to another location until a qualified
archaeologist can evaluate the significance of the find. If the resources are determined to
be historical resources or unique (pursuant to Section 15064.5 of the CEQA Guidelines),
the qualified archaeologist shall make recommendations prioritizing resource avoidance,
or, where avoidance is infeasible, data recovery.
MM-CUL-4 Worker Environmental Awareness Program (WEAP). The County shall require the
contractor to provide a cultural resources and tribal cultural resources sensitivity and
awareness training program (Worker Environmental Awareness Program [WEAP]) for all
personnel involved in project construction, including field consultants and construction
workers. The WEAP shall be developed in coordination with an archaeologist meeting the
Secretary of the Interior’s Professional Qualifications Standards for Archeology, as well as
culturally affiliated Native American tribes. The County will invite Native American
representatives from interested culturally affiliated Native American tribes to participate.
The WEAP shall be conducted before any ground-disturbing construction activities begin
at the project site. The WEAP shall include relevant information regarding sensitive
cultural resources and tribal cultural resources, including applicable regulations, protocols
for avoidance, and consequences of violating State laws and regulations.
The WEAP shall also describe appropriate avoidance and impact minimization measures
for cultural resources and tribal cultural resources that could be located at the project site
and shall outline what to do and who to contact if any potential cultural resources or tribal
cultural resources are encountered. The WEAP shall emphasize the requirement for
confidentiality and culturally appropriate treatment of any discovery of significance to
Native Americans and shall discuss appropriate behaviors and responsive actions,
consistent with Native American tribal values.

Property Owner(s): Keith Freitas
Project Location Address: 5698 Armstrong Road Byron, California 94514
Project Title: Byron Airport Development Program
Public Resources Code (PRC) § 3208.1 establishes well reabandonment responsibility when a
previously plugged and abandoned well will be impacted by planned property development or
construction activities. Local permitting agencies, property owners, and/or developers should be aware
of, and fully understand, that significant and potentially dangerous issues may be associated with
development near oil, gas, and geothermal wells.
The California Geologic Energy Mangagement Division (CalGEM) has received and reviewed the above
referenced project dated 8/2/2021. To assist local permitting agencies, property owners, and developers
in making wise land use decisions regarding potential development near oil, gas, or geothermal wells,
the Division provides the following well evaluation.
The project is located in Contra Costa County, within the boundaries of the following fields:
Any Field
Our records indicate there are 3 known oil or gas wells located within the project boundary as identified
in the application.
Page 1
• Number of wells Not Abandoned to Current Division Requirements as Prescribed by Law and
Projected to Be Built Over or Have Future Access Impeded by this project: 0
• Number of wells Not Abandoned to Current Division Requirements as Prescribed by Law and
Not Projected to Be Built Over or Have Future Access Impeded by this project: 3
• Number of wells Abandoned to Current Division Requirements as Prescribed by Law and
Projected to Be Built Over or Have Future Access Impeded by this project: 0
• Number of wells Abandoned to Current Division Requirements as Prescribed by Law and Not
Projected to Be Built Over or Have Future Access Impeded by this project: 0
The Division categorically advices against building over, or in any way impeding access to, oil, gas, or
geothermal wells. Impeding access to a well could result in the need to remove any structure or
obstacle that prevents or impedes access including, but not limited to, buildings, housing, fencing,
landscaping, trees, pools, patios, sidewalks, roadways, and decking. Maintaining sufficient access is
considered the ability for a well servicing unit and associated necessary equipment to reach a well from
a public street or access way, solely over the parcel on which the well is located. A well servicing unit,
and any necessary equipment, should be able to pass unimpeded along and over the route, and should
be able to access the well without disturbing the integrity of surrounding infrastructure.
There are no guarantees a well abandoned in compliance with current Division requirements as
prescribed by law will not start leaking in the future. It always remains a possibility that any well may
start to leak oil, gas, and/or water after abandonment, no matter how thoroughly the well was plugged
and abandoned. The Division acknowledges wells plugged and abandoned to the most current Division
requirements as prescribed by law have a lower probability of leaking in the future, however there is no
guarantees that such abandonments will not leak.
The Division advises that all wells identified on the development parcel prior to, or during, development
activities be tested for liquid and gas leakage. Surveyed locations should be provided to the Division in
Latitude and Longitude, NAD 83 decimal format. The Division expects any wells found leaking to be
reported to it immediately.
Failure to plug and reabandon the well may result in enforcement action, including an order to perform
reabandonment well work, pursuant to PRC § 3208.1, and 3224.
PRC § 3208.1 give the Division the authority to order or permit the re-abandonment of any well where it
has reason to question the integrity of the previous abandonment, or if the well is not accessible or
visible. Responsibility for re-abandonment costs may be affected by the choices made by the local
Page 2
permitting agency, property owner, and/or developer in considering the general advice set forth in this
letter. The PRC continues to define the person or entity responsible for reabandonment as:
1. The property owner - If the well was plugged and abandoned in conformance with Division
requirements at the time of abandonment, and in its current condition does not pose an immediate
danger to life, health, and property, but requires additional work solely because the owner of the
property on which the well is located proposes construction on the property that would prevent or
impede access to the well for purposes of remedying a currently perceived future problem, then the
owner of the property on which the well is located shall obtain all rights necessary to reabandon the
well and be responsible for the reabandonment.
2. The person or entity causing construction over or near the well - If the well was plugged and
abandoned in conformance with Division requirements at the time of plugging and abandonment,
and the property owner, developer, or local agency permitting the construction failed either to obtain
an opinion from the supervisor or district deputy as to whether the previously abandoned well is
required to be reabandoned, or to follow the advice of the supervisor or district deputy not to
undertake the construction, then the person or entity causing the construction over or near the well
shall obtain all rights necessary to reabandon the well and be responsible for the reabandonment.
3. The party or parties responsible for disturbing the integrity of the abandonment - If the well was
plugged and abandoned in conformance with Division requirements at the time of plugging and
abandonment, and after that time someone other than the operator or an affiliate of the operator
disturbed the integrity of the abandonment in the course of developing the property, then the party
or parties responsible for disturbing the integrity of the abandonment shall be responsible for the
reabandonment.
No well work may be performed on any oil, gas, or geothermal well without written approval from the
Division. Well work requiring approval includes, but is not limited to, mitigating leaking gas or other
fluids from abandoned wells, modifications to well casings, and/or any other re-abandonment work. The
Division also regulates the top of a plugged and abandoned well's minimum and maximum depth below
final grade. CCR §1723.5 states well casings shall be cut off at least 5 feet but no more than 10 feet
below grade. If any well needs to be lowered or raised (i.e. casing cut down or casing riser added) to
meet this regulation, a permit from the Division is required before work can start.
The Division makes the following additional recommendations to the local permitting agency, property
owner, and developer:
1. To ensure that present and future property owners are aware of (a) the existence of all wells
located on the property, and (b) potentially significant issues associated with any improvements
Page 3
near oil or gas wells, the Division recommends that information regarding the above identified
well(s), and any other pertinent information obtained after the issuance of this letter, be
communicated to the appropriate county recorder for inclusion in the title information of the subject
real property.
2. The Division recommends that any soil containing hydrocarbons be disposed of in accordance
with local, state, and federal laws. Please notify the appropriate authorities if soil containing
significant amounts of hydrocarbons is discovered during development.
As indicated in PRC § 3106, the Division has statutory authority over the drilling, operation,
maintenance, and abandonment of oil, gas, and geothermal wells, and attendant facilities, to prevent,
as far as possible, damage to life, health, property, and natural resources; damage to underground oil,
gas, and geothermal deposits; and damage to underground and surface waters suitable for irrigation or
domestic purposes. In addition to the Division's authority to order work on wells pursuant to PRC §§
3208.1 and 3224, it has authority to issue civil and criminal penalties under PRC §§ 3236, 3236.5, and
3359 for violations within the Division's jurisdictional authority. The Division does not regulate grading,
excavations, or other land use issues.
If during development activities, any wells are encountered that were not part of this review, the
property owner is expected to immediately notify the Division's construction site well review engineer in
the Northern district office, and file for Division review an amended site plan with well casing diagrams.
The District office will send a follow-up well evaluation letter to the property owner and local permitting
agency.
Should you have any questions, please contact me at (661) 334-3665 or via email at

Rohit Sharma

Re: Byron Airport Development Program, County File Numbers: GP12-0003, DP14-3008, State Clearinghouse
Number: 2017092059
Mr. Barrios,
The Contra Costa Water District (District) appreciates the opportunity to comment on the Byron Airport
Development Program EIR (EIR) dated June 2021. The project is located in southeastern Contra Costa County,
south of Byron Hot Springs, west of the Clifton Court Forebay, north of the Harvey O. Banks Pumping Plan and
east of Armstrong Road.
The District is submitting comments in relation to the Phase 2 Los Vaqueros Reservoir Expansion (Phase 2
Expansion), a project of state-wide importance. The Phase 2 Expansion is a collaborative regional project that
will improve Bay Area water supply reliability and water quality while protecting Delta fisheries. The Phase 2
Expansion will also provide additional Delta ecosystem benefits as well as be able to deliver water to wildlife
refuges through its regional intertie (Transfer-Bethany Pipeline).
The EIR states on page 3-2, Cumulative Context, that “There are no currently proposed projects in the
immediate project vicinity” and for this reason the County relied on the project method from adopted plans
for its cumulative effect’s analysis. However, the District is in the permitting phase of the Phase 2 Expansion
which will increase the capacity of the existing 160-thousand acre foot (TAF) Los Vaqueros Reservoir to 275
TAF and, among other conveyance facilities, will construct the Transfer-Bethany Pipeline, an approximately
8.0 mile pipeline from the existing Transfer Facility, traversing the Byron Airport Property in the vicinity of
Armstrong Road, and continuing south to terminate at the California Aqueduct. Accordingly, the District
request that the Phase 2 Expansion, specifically the Transfer-Bethany Pipeline, be included in the cumulative
context and effects analysis of the EIR (i.e., construction, operation and maintenance effects of the Transfer-
Bethany Pipeline in the vicinity of the Byron Airport for resources areas where a cumulative condition is
reasonably foreseeable).
On background, the U.S. Department of the Interior, Bureau of Reclamation, California – Great Basin Region
(Reclamation) as the lead agency under the National Environmental Policy Act (NEPA) and the District as the
lead agency under California Environmental Quality Act (CEQA) previously released a joint Draft EIS/EIR in

Number: 2017092059

February 2009. The Draft EIS/EIR included analysis of four action alternatives: two that include a reservoir
expansion to 275 TAF and a Transfer-Bethany Pipeline that traversed along Armstrong Road. Multiple County
departments including the Department of Conservation and Development, Flood Control and Water
Conservation District, and Public Works Department provided comments on the Draft EIS/EIR. The Final
EIS/EIR (certified March 31, 2010), was later modified by the August 2013 EIR Addendum #1 (together, the Final
EIS/EIR). The Final EIS/EIR analyzed, among other alternatives, a Timing Variant under which Los Vaqueros
Reservoir would be expanded first to 160 TAF (Phase 1 Expansion) and later to 275 TAF (Phase 2 Expansion).
Ultimately, the Phase 1 Expansion, which did not include the Transfer-Bethany Pipeline, was approved and
completed in 2012.
On June 29, 2017, Reclamation and the District published the Draft Supplement to the Final EIS/EIR which
disclosed that the Transfer-Bethany Pipeline would start at the same place on the north end and travel along
the same alignment as proposed in the Final EIS/EIR for the first 7.1 miles to an area south of the Byron
Airport. Beyond the 7.1-mile marker, the Transfer-Bethany Pipeline was modified, consistent with the
Reclamation 2016 Value Planning Study, to fully avoid tunneling and terminate at the California Aqueduct
rather than the Bethany Reservoir. The County Flood Control and Water Conservation District commented on
the document. On March 8, 2018, in response to concern raised about the Transfer-Bethany Pipeline, the
District and Reclamation held a meeting with the Department of Conservation and Development, Department
of Public Works and Airports division.
On February 28, 2020, Reclamation and the District published the Final Supplement to the Final EIS/EIR. On
May 13, 2020, the Final Supplement to the Final EIS/EIR was certified and the Phase 2 Expansion, including the
Transfer-Bethany Pipeline, was adopted by the District’ Board (Resolution-No-20-006-PDF (ccwater.com).
Reclamation plans to execute it’s Record of Decision in early 2022. All environmental documents related to
the Los Vaqueros Reservoir Expansion Project are available here: Environmental Documents | Contra Costa
Water District, CA (ccwater.com).
Thank you for your consideration of District comments to include the Phase 2 Expansion in the cumulative
context and effects analysis. The District looks forward to continued coordination with the various
department at the County on the Transfer-Bethany Pipeline. If you have any questions about this letter or the
Phase 2 Expansion please do not hesitate to contact me.
Respectfully,

RE: Comments on the Draft Environmental Impact Report for the Byron
Airport Development Program, SCH# 2017092059
Dear Daniel Barrios:
Thank you for the opportunity to review and comment on the Byron Airport
Development Program Draft Environmental Impact Report (Draft EIR) prepared by
the Contra Costa County Department of Conservation and Development (DCD). The
Delta Stewardship Council (Council) recognizes the objectives of the Byron Airport
Development Program (project), as described in the Draft EIR: Contra Costa County
intends to amend its Airport Land Use Compatibility Plan (ALUCP), Contra Costa
County General Plan (General Plan), and Planned Unit District zoning to
substantially broaden the range of uses allowed “by-right” on airport property. Of
interest to the Council are areas located outside of the 2006 voter-approved urban
limit line, including portions of the new safety/compatibility zones, specifically, B1
and B3 (new Safety Zone 2), and B2 (new Safety Zone 3).
The Council is an independent state agency established by the Sacramento-San
Joaquin Delta Reform Act of 2009, codified in Division 35 of the California Water
Contra Costa County, Department of Conservation and Development
Attn: Daniel Barrios
August 30, 2021
Page 2
Code, sections 85000-85350 (Delta Reform Act). The Delta Reform Act charges the
Council with furthering California’s coequal goals of providing a more reliable water
supply and protecting, restoring, and enhancing the Sacramento-San Joaquin River
Delta (Delta) ecosystem. (Water Code, § 85054.) The Delta Reform Act further states
that the coequal goals are to be achieved in a manner that protects and enhances
the unique cultural, recreational, natural resource, and agricultural values of the
Delta as an evolving place. The Council is charged with furthering California’s
coequal goals for the Delta through the adoption and implementation of the Delta
Plan. (Wat. Code, § 85300.)
Pursuant to the Delta Reform Act, the Council has adopted the Delta Plan, a
comprehensive long-term management plan for the Delta and Suisun Marsh that
furthers the coequal goals. The Delta Plan contains regulatory policies, which are
set forth in California Code of Regulations, Title 23, sections 5001-5015. A state or
local agency that proposes to carry out, approve, or fund a qualifying action in
whole or in part in the Delta, called a "covered action," is required to prepare a
written certification of consistency with detailed findings as to whether the covered
action is consistent with the Delta Plan and submit that certification to the Council
prior to implementation of the covered action. (Wat. Code, § 85225.) Water Code
section 85057.5, subdivision (a), defines a covered action as a plan, program, or
project as defined pursuant to Section 21065 of the Public Resources Code that
meets all the following conditions:
1. Will occur in whole or in part within the boundaries of the legal Delta
(Water Code, §12220) or Suisun Marsh (Pub. Resources Code, §
29101). The approximate boundaries of these areas are publicly
available on the Open Data Portal at
https://data.ca.gov/dataset/legal-delta-boundary and
https://data.ca.gov/dataset/suisun-marsh-boundary. The eastern
portion of Byron Airport is located within the Delta.
2. Will be carried out, approved, or funded by the State or a local public agency.
Contra Costa County is the local public agency that will approve and carry out
the project.
3. Will have a significant impact on the achievement of one or both of the
coequal goals or the implementation of a government-sponsored flood
control program to reduce risks to people, property, and State interests in
Contra Costa County, Department of Conservation and Development
Attn: Daniel Barrios

the Delta. The project would have a significant impact on the achievement of
the coequal goal to protect, restore, and enhance the Delta ecosystem.
4. Is covered by one or more of the regulatory policies contained in the Delta
Plan (Cal. Code Regs., tit. 23, §§ 5003-5015). Delta Plan regulatory policies
that may apply to the project are discussed below.
The State or local agency approving, funding, or carrying out the project must
determine if the project is a covered action and, if so, submit a Certification of
Consistency to the Council prior to project implementation. (Wat. Code, § 85225;
Cal. Code Regs., tit. 23, § 5001(j)(3).)
COMMENTS REGARDING DELTA PLAN POLICIES AND POTENTIAL
CONSISTENCY CERTIFICATION
The following section describes the Delta Plan regulatory policies that may apply to
the proposed project based on the available information in the Draft EIR. This
information is offered to assist DCD to prepare environmental documents that
could be used to support a future Certification of Consistency for the project. This
information may also assist DCD to describe the relationship between the project
and the Delta Plan in the Final EIR.
General Policy 1: Detailed Findings to Establish Consistency with the Delta
Plan
Delta Plan Policy G P1 (Cal. Code Regs., tit. 23, § 5002) specifies what must be
addressed in a Certification of Consistency for a covered action. The following is a
subset of policy requirements which a project shall fulfill to be considered
consistent with the Delta Plan:
Mitigation Measures
Delta Plan Policy G P1(b)(2) (Cal. Code Regs., tit. 23, § 5002(b)(2)) requires
covered actions not exempt from the California Environmental Quality Act
(CEQA) must include all applicable feasible mitigation measures adopted and
incorporated into the Delta Plan as amended April 26, 2018 (unless the
measures are within the exclusive jurisdiction of an agency other than the
agency that files the Certification of Consistency), or substitute mitigation
measures that the agency finds are equally or more effective. These
Contra Costa County, Department of Conservation and Development
Attn: Daniel Barrios
August 30, 2021
Page 4
mitigation measures are identified in Delta Plan Appendix O and are
available at: https://deltacouncil.ca.gov/pdf/delta-plan/2018-appendix-o-
mitigation-monitoring-and-reporting-program.pdf.
The Draft EIR proposes project mitigation measures for potentially significant
impacts to aesthetics; air quality; biological resources; cultural resources;
geology, soils, and minerals; greenhouse gas emissions; hazards and
hazardous materials; hydrology and water quality; and transportation and
traffic. The mitigation measures adopted in the Final EIR must be equally or
more effective than applicable feasible Delta Plan mitigation measures. In a
future Certification of Consistency for the project, DCD should document
how the adopted mitigation measures are equally or more effective than the
applicable mitigation measures contained in Delta Plan Appendix O.
Best Available Science
Delta Plan Policy G P1(b)(3) (Cal. Code Regs., tit. 23, § 5002(b)(3)) states that
actions subject to Delta Plan regulations must document use of best
available science as relevant to the purpose and nature of the project. The
Delta Plan defines best available science as “the best scientific information
and data for informing management and policy decisions.” (Cal. Code Regs,
tit. 23, § 5001 (f).) Best available science is also required to be consistent with
the guidelines and criteria in Appendix 1A of the Delta Plan
(https://deltacouncil.ca.gov/pdf/delta-plan/2015-appendix-1a.pdf).
Delta as Place Policy 1: Locate New Urban Development Wisely
Delta Plan Policy DP P1 (Cal. Code Regs., tit. 23, § 5010) places certain limits
on new urban development within the Delta. New residential, commercial,
or industrial development must be limited to areas that city or county
general plans designate for such development as of the date of the Delta
Plan’s adoption (May 16, 2013). In Contra Costa County, new residential,
commercial, and industrial development within the Delta must be limited to
areas within the 2006 voter-approved urban limit line (ULL) (Cal. Code
Regs., tit. 23, § 5010(a)(2)). This policy is intended to strengthen existing
Delta communities while protecting farmland and open space, providing
land for ecosystem restoration needs, and reducing flood risk.
Contra Costa County, Department of Conservation and Development
Attn: Daniel Barrios
August 30, 2021
Page 5
According to the Draft EIR, the General Plan designations for the Byron Airport
property are Public/Semi-Public (PS) and Open Space (OS) (Draft EIR, p. 2-6).
Although most of the Byron Airport is located within the ULL, the portion of the
Airport designated as Open Space is outside the ULL. This area is subject to Delta
Plan Policy DP P1 (Cal. Code Regs., tit. 23, § 5010). Although the Draft EIR states
that the General Plan designation for the existing airport property will not change,
ALUCP Policy 5-77 would be amended to reflect the new compatibility zone (Zone B-
1 would become Safety Zone 2) designations and additional uses at the airport that
may be found compatible under the updated ALUCP for Byron Airport (Draft EIR p.
2-6).
The project proposes acquisition of an 11.7-acre property on Armstrong Road that
is currently designated for Agricultural use and update the general plan designation
to PS (Draft EIR, p. 2-6). This proposed acquisition is located within the ULL, and is
therefore not subject to DP P1.
Based on review of the Draft EIR, the locations of the project site and the ULL, and
the existing and proposed General Plan designations, the project may be consistent
with DP P1, although DCD must identify this in a Certification of Consistency for the
project. DCD should revise the Final EIR to identify DP P1 requirements in the
regulatory setting of the Land Use and Planning section.
CLOSING COMMENTS
The Council will continue to track the Byron Airport Development Program’s
progress and invites DCD to engage in early consultation as future program
updates are considered, in order to discuss project features and mitigation
measures that would promote consistency with the Delta Plan.
More information on covered actions, early consultation, and the certification
process can be found on the Council website,
https://coveredactions.deltacouncil.ca.gov. Please contact
Avery.Livengood@deltacouncil.ca.gov, Environmental Program Manager, with any

states that preservation in place is the preferred manner of mitigating impacts to archaeological
sites. Section 15126.4, subd. (b)(3) of the CEQA Guidelines has been interpreted by the
California Court of Appeal to mean that “feasible preservation in place must be adopted to
mitigate impacts to historical resources of an archaeological nature unless the lead agency
determines that another form of mitigation is available and provides superior mitigation of
impacts.” Madera Oversight Coalition v. County of Madera (2011) 199 Cal.App.4th 48,

I. PROJECT SUMMARY
The proposed project is a County-initiated General Plan Amendment (GPA), Development
Plan Modification (DPM), Rezone, and Airport Land Use Compatibility Plan (ALUCP)
Amendment for the Byron Airport to expand the range of uses allowed on the airport
property. The proposed GPA would include revised policies that update and clarify the range
of land uses and activities allowed at Byron Airport, similar to those already adopted for the
County’s other general aviation airport, Buchanan Field in Concord, as well as redesignation
of an 11.7-acre parcel to be acquired by the County from AL to PS. The current Development
Plan for the airport would be modified to permit all of the new uses either by-right or with
approval of a land use (conditional) permit. The DPM would also establish certain
development standards, such as maximum building heights, maximum floor area,
landscaping requirements, etc. The rezone would change the 11.7-acre parcel from A-3 to
P-1 to be part of the Byron Airport Development Program. The ALUCP would be updated
with new policies and maps specific to Byron Airport, which would reflect the 2017 Airport
Layout Plan for Byron Airport, the 2005 Byron Airport Master Plan, and guidance set forth in
the most recent version of the Caltrans California Airport Land Use Planning Handbook.

III. GENERAL INFORMATION
A. General Plan: The subject site’s General Plan land use designations include Public and
Semi-Public (PS), Open Space (OS), and Agricultural Lands (AL). The PS designation
includes properties owned by public governmental agencies such as libraries, fire
stations, schools, etc., The OS designation includes publicly owned open space lands
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262

which are not designated as Public and Semi-Public, Watershed, or Parks and Recreation.
Lands designated Open Space include, without limitation, wetlands and tidelands and
other areas of significant ecological resources, or geologic hazards. OS also includes
privately-owned properties for which future development rights have been deeded to a
public agency or private entity, such as a land trust. The primary purpose of the AL
designation is to preserve and protect lands capable of and generally used for the
production of food, fiber, and plant materials.
The proposed project is located primarily within the PS designation, in which public
airports are a compatible use. The existing aviation facilities and the master-planned
development areas are designated as PS. The proposed project includes the
redesignation of the 11.7-acre parcel from AL to PS, which, after its redesignation, would
result in the entire project being located within the PS designation. The remainder of the
airport property is designated OS, consistent with the habitat management use for the
non-developable airport property.
B. Zoning: Byron Airport is zoned Planned Unit District (P-1); the 11.7-acre parcel is zoned
Heavy Agricultural District (A-3).
C. California Environmental Quality Act (CEQA) Status: The Department of Conservation
and Development determined that the project required preparation of an EIR and, in
accordance with CEQA, distributed a Notice of Preparation (NOP) on September 21,
2017. The Draft EIR was released for public review on July 1, 2021, with the 60-day public
comment period ending on August 30, 2021. The Final EIR is included in this staff report
for the County Planning Commission’s consideration.
The EIR identified potentially significant environmental impacts that would occur if the
project was implemented and recommended mitigation measures that would reduce
most, but not all, of the potentially significant impacts to less-than-significant levels;
some impacts would remain significant and unavoidable. The attached CEQA Findings
contain a statement of overriding considerations for the significant and unavoidable
impacts. All impacts and mitigation measures are spelled out in the attached Mitigation
Monitoring and Reporting Program (MMRP). All mitigation measures are also included
in the attached conditions of approval. Further discussion of the project’s environmental
impacts is provided in Section VII below.
IV. SITE/AREA DESCRIPTION
Existing Site Condition: Byron Airport is located in southeastern Contra Costa County. The
airport property consists of 1,427 acres, including 1,307 acres south of Armstrong Road and
120 acres north of Armstrong Road. The proposed Byron Airport Development Program
(project) site excludes the 120 acres north of Armstrong Road but includes an 11.7-acre
parcel located between the airport property and the Bethany Irrigation District Canal, for a
total of approximately 1,319 acres. The project site includes the existing airport facilities and
areas proposed for development (referred to as the development area). However, most of
the project site is reserved for habitat management.
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262

Byron Airport has two nonintersecting runways, each with a parallel taxiway and several
connector taxiways. General aviation facilities are generally concentrated in the west-facing
“V” formed by the two runways and include aircraft surface storage, runway apron, hangars,
and office space. The majority of these facilities were constructed when the airport was built
in the early 1990s.
Byron Airport does not have a control tower. Buildings include the 2,400-square-foot
administration building (500 Eagle Court) and a 7,500-square-foot maintenance hangar (505
Eagle Court). The administration building is served by 18 parking spaces. A fuel farm is
located southeast of the maintenance hangar. Accessory structures include a 300-square-
foot pump house for fire protection, east of the intersection of the two runways. A small
building on the north side of the airport (6900 Falcon Way) was part of the original Byron
Airpark and is currently leased to Bay Area Sky Diving.
Hangars are arranged in rows, starting northwest of the administration building. There is a
28-unit T-hangar constructed in 1996, two rows of portable T-hangars (39 units), and two
executive hangars (10 and 12 units). The Byron Jet Center (760 Osprey Court) is located
northwest of the executive hangars. Tie downs for based aircraft and transient aircraft are
located between the hangars and the taxiways. A wash rack is located at the east side of the
executive hangar row. Wastewater from the wash rack drains though an oil–water separator
to a leach field located to the east, between the wash rack and Taxiway A.
Electrical power is supplied by Pacific Gas & Electric Company via Holey Road. There is no
natural gas service at the airport. The on-site water system consists of a domestic well with
a 4,000-gallon holding tank, booster pump, and chlorinator; however, this water supply is
non-potable. Drinking water is provided by bottled water deliveries to the airport. The
sanitary system consists of a 3,000-gallon septic tank and lift station that pumps to a leach
field located southwest of the aircraft apron.
Surrounding Land Use: Byron Airport is located on the western edge of the Central Valley.
Byron Hot Springs, a now abandoned resort and former World War II prisoner-of-war camp,
is located north of the airport. Agricultural and rural residential uses border the east and
west sides of the airport property. To the south are agricultural lands and property owned
by East Bay Regional Park District. Nearby communities include Byron, approximately 2.5
miles north, Discovery Bay 4 miles to the northeast, and Mountain House, approximately 4
miles southeast.
IV. BACKGROUND
The original Byron Airport Master Plan (Airport Master Plan) was adopted in 1986, and the
airport was opened in 1994. The Airport Master Plan was updated in 2005 and identifies a
20-year plan to support aviation activities at the airport. The 2005 Airport Master Plan also
identifies potential development opportunities on airport property to increase airport
revenue and achieve economic self-sufficiency. In 2015, the County identified a suite of
proposed land uses for development on airport property, building on the framework of the
2005 Airport Master Plan. The uses included aviation reserve land uses, which would be
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Page 5 of 15
directly associated with aircraft operations (e.g., hangar development, aircraft repair and
maintenance), and aviation-related land uses, which would not be aeronautical uses but
would be compatible with on-going aircraft operations (i.e., aviation-compatible uses).
Examples of aviation-compatible uses include warehouse use and light industry.
The County’s current General Plan policies, zoning regulations, and ALUCP policies specific
to the airport would not accommodate many of the proposed land uses. Therefore, the
County’s Department of Conservation and Development and Public Works Department –
Airports Division are working collaboratively to amend the General Plan, zoning, and ALUCP
to enable on-site development in accordance with the proposed Airport Master Plan, as well
as the Byron Airport Planned Unit District (P-1) is being amended to identify additional
aviation-reserve uses and aviation-compatible uses that would be permitted by right.
The project would provide for both aviation development and non-aviation (airport-related)
development. Aviation uses include aircraft storage, administrative facilities, instructional
facilities, fixed base operators, pilot and passenger terminal improvements, cargo facilities,
and aircraft repair and service. Non-aviation development includes a wide range of
industrial, commercial, and office uses that benefit from proximity to the airport and the
regional roadway network. These uses may include warehousing and distribution; light
manufacturing; research and development; regional retail, including construction materials
and home goods; service commercial; and offices. Local retail and food service may also be
provided to serve the airport and local residents.
V. PROJECT DESCRIPTION
A. Objectives: The County identified the following project objectives:
1. Develop airport facilities to support the types of development envisioned in the
Airport Master Plan and subsequent airport planning efforts.
2. Achieve economic self-sufficiency of the airport through the development of
airport-related land uses.
3. Protect current and future airport operations from incompatible land uses.
4. Provide a streamlined planning framework for future development consistent
with the General Plan and the ALUCP.
B. General Plan Amendment: The County General Plan designates the existing aviation
facilities and the master-planned development areas as Public/Semi-Public (PS). The
remainder of the airport property is designated as Open Space (consistent with the
habitat management use for the non-developable airport property). The General Plan
designation for the existing airport property will not change. The 11.7-acre acquisition
parcel would be redesignated from Agricultural Lands (AL) to PS to be consistent with
the rest of the developable airport property (see Attachment 4, Proposed General Plan
Amendment Map).
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Page 6 of 15
General Plan Policy 5-66 states, “Establishment of commercial, industrial or residential
development around the planned airport shall not be allowed.” This policy would be
amended to specify that commercial or industrial development would be allowed on
airport property if it is consistent with the ALUCP and the Airport Master Plan for Byron
Airport. Policy 5-77 would be updated to reflect the new compatibility zone designations
(Zone B-1 would become Safety Zone 2) and the additional uses at the airport that may
be found compatible under the updated ALUCP for Byron Airport. See Attachment 5 for
the full text of the General Plan policy changes.
C. Airport Land Use Compatibility Plan Update: Every county in California that contains at
least one public airport must prepare an Airport Land Use Plan (also known as an Airport
Land Use Compatibility Plan), per the State Aeronautics Act (Public Utilities Code Section
21001 et seq.). The purpose of ALUCPs is to minimize the public’s exposure to excessive
noise and safety hazards while providing for the orderly expansion of airports. ALUCPs
achieve this by identifying land use types and intensities that are compatible with four
key factors: safety, noise, airspace protection, and overflight. The California Department
of Transportation (Caltrans), Division of Aeronautics, provides guidance on airport land
use planning in its California Airport Land Use Planning Handbook.
The ALUCP for Byron Airport was adopted in 2000, with minor modifications in 2006 and
2016. The current ALUCP reflects the original 1986 Airport Master Plan for the East
Contra Costa County Airport (now Byron Airport). The Byron Airport Master Plan was
updated in 2005. In addition, the Airport Layout Plan—required by the Federal Aviation
Administration and a main component of the Airport Master Plan—was updated in 2016.
The standards used in the current ALUCP for Byron Airport are based on the 1993 edition
of the Airport Land Use Planning Handbook. Caltrans has updated this guidance
document twice since that time, in 2002 and 2011. Thus, the current ALUCP for Byron
Airport does not reflect the latest planning and forecasts for the airport, and is based on
dated compatibility planning guidance. The 2016 Airport Layout Plan was update is not
reflected in the current ALUCP for Byron Airport. The effect is an ALUCP that does not
allow the type of development envisioned in the Airport Master Plan, which would
provide for the economic development and fiscal self-sufficiency of Byron Airport.
The proposed ALUCP update for Byron Airport would revise the policies for Byron
Airport, consistent with current Caltrans California Airport Land Use Planning Handbook
and the policy framework in effect at Buchanan Airport. The Countywide policies in the
ALUCP affecting Byron Airport would not change. Key changes for Byron Airport policies
are described below by category: safety, noise, airspace protection, and overflight.
1. Safety: Several important changes would be made to Byron Airport’s safety
policies. These are driven primarily by applying the latest Caltrans guidance to
the airport. The current ALUCP for Byron Airport uses six “composite” zones
known as zones A, B1, B2, C1, C2, and D. These zones combine noise and safety
criteria to determine compatible land uses. The proposed ALUCP update would
identify six safety zones (1 through 6) consistent with the current Airport Land
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Page 7 of 15
Use Planning Handbook. By using more carefully defined safety zones and by
addressing noise compatibility separately, a greater range of development types
would be allowed. In addition, applying current Airport Land Use Planning
Handbook standards for non-residential development would increase the
intensity of development that would be allowed, and thereby support the
County’s goals for economic development at the airport.
2. Noise: The proposed ALUCP update for Byron Airport would separate the noise
criteria from the safety criteria when determining compatible use. Noise
compatibility is based on noise contours developed from forecasted aviation
activity. The aviation forecasts for the airport remain valid and would not be
revised as part of the proposed ALUCP update. Therefore, the noise contours
would not change. The commercial and light industrial uses planned for the
airport are not considered to be noise-sensitive uses. Therefore, separating the
noise criteria from the safety zones would increase the range and intensity of
non-residential land uses.
3. Airspace Protection: Airspace protection policies regulate development that may
interfere with the safe navigation of aircraft, including physical structures or
potential hazards such as dust, smoke, light/glare, and wildlife. Minor changes
would be made to airspace policies to reflect the 2016 Airport Layout Plan,
including runway approach profiles. However, no significant changes would be
made to the policies, and there would be no effect on allowable land uses.
4. Overflight: Overflight policies do not regulate land use but identify the areas
subject to noise from overflight (as compared to noise from aircraft approaches
and departures). The overflight area, along with airspace protection discussed
above, helps to define the airport influence area, in which home buyers must be
notified of the presence of the airport. Overflight policies also identify areas
where aviation easements (dedicating airspace rights to the airport) should be
acquired. The notification area would be slightly larger in the proposed ALUCP
update for Byron Airport to reflect the 2016 Airport Layout Plan, but there would
be no change to policies that would affect allowable land uses or future
development.
D. Development Plan Modification and Rezone: The airport property is currently zoned P-
1. The P-1 zoning is intended to allow diversification in the relationship of various uses,
buildings, structures, lot sizes, and open space areas while ensuring compliance with the
General Plan and the intent of the County Code in requiring adequate standards
necessary to satisfy the requirements of public health, safety, and general welfare.
Currently, the Byron Airport P-1 zoning only allows aviation-related uses, agriculture,
and open space. The amended Planned Unit District will identify four separate
development areas: Aviation, Airport Related, Low-Intensity Use, and Habitat
Management (see Attachment 7, Proposed Site Plan). These areas are further described
below. The most important change would be to the airport-related uses, which would
allow non-residential development that is compatible with the ALUCP for Byron Airport.
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Page 8 of 15
These uses would include light industry, warehousing and logistics, commercial, and low-
intensity office. In addition, the 11.7-acre parcel to be acquired by the County would be
rezoned from A-3 to P-1 in order to be included as part of the Byron Airport
Development Program (see Attachment 6, Proposed Rezone Ordinance Map). The Byron
Airport Development Program also includes the following modifications to the P-1:
1. Aviation: A total of 23.5 acres is designated for aviation uses, located adjacent to
the taxiways and runways. The aviation area is adjacent to a developed 10.5-acre
aircraft storage area and 9.7-acre aircraft parking area south of the main runway
(Runway 12-30). Proposed land uses in the aviation area include airport
infrastructure (e.g., control tower, terminals), hangars, fixed-base operators,
businesses that directly support aviation and travel (e.g., aircraft service and fuel,
rental car facilities, pilots lounge, meeting facilities), and businesses that directly
rely on aviation (e.g., agricultural aviation, aerial surveys and photography, air
charter businesses, air cargo, just-in-time delivery).
2. Non-Aviation (Airport Related): Approximately 46.6 acres of Byron Airport is
designated for non-aviation uses. This includes 34.9 acres east of the main
runway on the existing airport property, and 11.7 acres in the adjacent parcel.
The 46.6 acres would support commercial and light-industrial uses that are
compatible with airport operations and would benefit from being located at an
airport, with access to Highway 4, Interstate 205, and Interstate 580. A variety of
retail, service, warehouse and distribution, light manufacturing, and low-density
office uses would be allowed.
3. Low-Intensity Use: The areas adjacent to the ends of the primary runway and
within the “no build” area adjacent to the runway, approximately 31 acres, are
designated as low-intensity use. No structures would be allowed within this area.
Infrastructure improvements may be allowed within this area.
4. Habitat Management Lands: Most of the project site, approximately 814 acres, is
owned and managed by the County as wildlife habitat, consistent with the East
Contra Costa County Habitat Conservation Plan. The proposed project does not
propose any changes to habitat management lands.
5. Development Reserve: The 2005 Airport Master Plan identified a potential
development area larger than the one currently under consideration. The areas
that have been removed from the aviation and non-aviation development area
are identified as “development reserve” in the proposed site plan. There are no
land uses assigned to this category, it merely denotes an area that was previously
identified for potential development in the 2005 Airport Master Plan but is no
longer considered part of the proposed development program.
6. Development Scenario: Taking into account the land use areas described above
and the proposed safety zones, DCD and Airports Division staff developed a
preferred development scenario. This scenario represents a reasonable
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Page 9 of 15
distribution of compatible land uses on the airport property and forms the basis
of the impacts analysis in the EIR. The development scenario, presented in Table
1, assigns a percentage of available acreage to the various uses (e.g., light
industry), and estimates the potential building area as increments of 1,000 square
feet for those uses based on floor-to-area ratio. The number of people who may
occupy the site at any given time was then calculated using intensity factors from
the Airport Land Use Planning Handbook and the County’s General Plan. The
percentages assigned to each non-aviation land use are estimated, but future
land use demand would drive the actual development scenario. As long as the
overall building area is not exceeded, the impacts of development is not
anticipated to exceed the analysis conducted as part of this project. Ongoing
monitoring of land uses would ensure that incoming land uses do not exceed the
impacts analysis of this proposed program.

VI. PUBLIC CONSULTATION & COMMENTS ON THE EIR
The Department conferred with a number of federal, State, and local agencies and other
County departments prior to and during preparation of the EIR. Correspondence was
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Page 10 of 15
received in response to the NOP, and written comments were received from the following
agencies and organizations during the public comment period for the Draft EIR:
• Wilton Rancheria
• California Department of Conservation – Geologic Energy Management Division
• Delta Stewardship Council
• Contra Costa Water District
All correspondence received during and after the 60-day public comment period for the
Draft EIR and all responses to those comments are included in the Final EIR.
VII. SUMMARY OF ENVIRONMENTAL IMPACTS
The Draft EIR identifies environmental impacts which would occur if the project was
implemented. Potentially significant and/or significant and unavoidable impacts were
identified in the following Draft EIR topic areas:
A. Aesthetics: Discussed in detail in Draft EIR Section 3.1 (pages 3.1-1 to 3.1-53) and in the
Final EIR. The DEIR identified potentially significant impacts to views from surrounding
roadways, including Armstrong Road and Byron Hot Springs Road. However, all
potentially significant impacts can be mitigated to less-than-significant levels.
B. Air Quality: Discussed in detail in Draft EIR Section 3.2 (pages 3.2-1 to 3.2-42) and in the
Final EIR. Significant and unavoidable impacts would occur during both construction
and operation.
C. Biology: Discussed in detail in Draft EIR Section 3.3 (pages 3.3-1 to 3.1-38) and in the
Final EIR. The DEIR identified potentially significant impacts to a variety of special-status
plant and animal species and their habitats. However, all potentially significant impacts
can be mitigated to less-than-significant levels.
D. Cultural Resources: Discussed in detail in Draft EIR Section 3.4 (pages 3.4-1 to 3.4-22)
and in the Final EIR. The project site is in the vicinity of Northern Valley Yokut territory,
and the surrounding area is known to contain numerous archeological and historical
resources. The Draft EIR identified potentially significant impacts to cultural resources.

Reporting Program.
VIII. STAFF DISCUSSION
A. Economic Development: Byon Airport currently operates at an annual net deficit. In order
to develop economically beneficial uses on the airport, development intensities would
be increased to a level more consistent with current California Airport Land Use Planning
Handbook guidance. In addition, by de-coupling the noise and safety criteria, a greater
range of industrial and commercial uses could be allowed at the airport. This approach
would also create consistency with Buchanan Field, which does not use composite
compatibility zones.
The proposed project would help implement General Plan Goal 5-Q, to encourage the
development and operation of two general purpose public airports in the county, by
providing for the economic development and financial self-sufficiency of Byron Airport.
The General Plan policies regarding the airport would be amended to clarify that
compatible non-aviation uses would be allowed on airport property. General Plan Policy
5-66 would be amended to specify that commercial or industrial development would be
allowed on-airport if it is consistent with the ALUCP and the Byron Airport Master Plan.
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Page 12 of 15
The P-1 district for Byron Airport would also be revised to identify the land use categories
used in the ALUCP: aviation, non-aviation, low intensity, and habitat management.
Additional land uses that could be allowed within the aviation and non-aviation areas
would be identified, as discussed in Draft EIR Section 2.6, Proposed Land Uses and
Zoning. The P-1 modification would specify that all proposed land uses must be
reviewed by County staff for consistency with the current ALUCP. The zoning would also
implement the ALUCP and General Plan standards for compatible land use, including
height restrictions. Allowing for more land uses and increased intensities within the
Byron Airport planning area would increase revenue for the airport and County and, with
the types of aviation-related uses included in the project, potentially make Contra Costa
County a hub of aviation technology and innovation in the Bay Area.
Not only would increasing the economic viability of Byron Airport help it operate in a
financially beneficial way to the County, but it would also help support the Jobs/Housing
balance in East Contra Costa County. According to General Plan Table 2-4, the projected
jobs/hosing ratio for East County in 2020 was 0.45 jobs per resident. This low ratio results
in a large population of East County residents commuting out of the county for work,
rather than commuting locally. This mass exodus from East County communities creates
significant traffic along local roads and highways, among other negative impacts to the
environment and quality of life. Providing new, high quality economic opportunities for
residents in East County would help make a dent in the jobs/housing ratio, especially
with the rapidly increasing population growth in East County.
B. Transportation and Traffic: As discussed in detail in Draft EIR Section 3.13 (pages 3.13-1
to 3.13-54) and in the Final EIR, significant and unavoidable impacts would occur as a
result of traffic generated by operation of individual development projects under the
scope of this development program. The Vehicle Miles Traveled (VMT) per employee for
the project is 21.2, compared to 14.0 for the county and 14.9 for the Bay Area. A slight
decrease in VMT per employee under the “with project” conditions compared to the
“without project” conditions indicates that the project would improve VMT efficiency in
the region. However, it should be noted that the VMT “significance of impact” threshold
requires comparison of the project VMT with the regional average (i.e., Bay Area
Average), and not a comparison of with project and no project scenarios. The County
threshold for Employment Projects (office, industrial, and institutional projects) is that
the project VMT should be 15% below Bay Area average commute VMT per employee
(i.e., home-based work VMT per employee). The project’s VMT per employee (21.2) is
higher than the Bay Area VMT per employee (14.9). To meet the threshold of 15% below
Bay Area Average and have a less than significant VMT impact, the HBW VMT per
employee for the project should be approximately 12.7, which would require a 40%
reduction. Therefore, the Draft EIR identified this as a potentially significant VMT impact.
Transportation demand management strategies and mitigation measures that can
potentially achieve VMT reductions are provided in Draft EIR Section 3.13.5 and the
MMRP.

The project also has the potential to increase the volume of truck traffic on the roadway
network to serve warehousing and light industrial development. Although regional
roadways, such as Byron Highway and State Route (SR-4), already safely handle
significant volumes of truck traffic, the rural roads providing access to Byron Airport may
not support the increase in truck traffic. Existing traffic volumes can be handled on these
roads, but they may be inadequate for increased volumes of project-related traffic,
including increased truck traffic. As such, the Draft EIR identified this as a potentially
significant impact. Therefore, the County or future developers would construct the street
improvements along Armstrong Road, Byron Hot Springs Road, and Holey Road
described in MM-TRAF-9 to reduce access impacts related to heavy truck traffic.
Finally, due to the potential for the proposed project to add traffic to Caltrans facilities
within the traffic impact study area, the Caltrans Mountain House Parkway/I-205
westbound ramps and Mountain House Parkway/I-205 eastbound ramps were analyzed
for queuing impacts. When comparing the Future Year 2040 scenario with the addition
of the proposed project, queueing is forecasted to increase for all vehicle movements
during the AM peak hour at the Mountain House Parkway/I-205 westbound ramps;
vehicle traffic would continue to spill into the mainline lanes in Future Year 2040 “no
Project” and “plus Project” conditions. No current funded or planned improvements are
identified at the I-205 westbound ramps with Mountain House Parkway. The SR-239
Feasibility Study Final Report identifies potential alignments for the proposed SR-239
corridor between SR-4 to the north and I-580 and/or I-205 to the south, which would
reduce traffic volumes on I-580, Vasco Road, and Byron Highway (SR-239 is a proposed
roadway connecting Vasco Road in Contra Costa County to the I-580/I-205 interchange
in Alameda County or I-205 in San Joaquin County). As such, shifts in regional traffic
patterns could also reduce congestion and queuing at the Mountain House Parkway/I-
205 westbound ramps. However, as the SR-239 Feasibility Study does not identify
specific improvements, nor are specific improvements planned or funded in the area,
hazards related to queuing at this off-ramp would remain significant and unavoidable.
C. Utilities: The project site is not connected to public water services; instead, the airport
relies on existing on-site water wells and a 4,000-gallon on-site water tank for its
domestic, non-potable water. Bottled water is used for drinking water. Development of
the proposed project would exceed the capacity of the existing system, resulting in a
potentially significant impact. Currently, the well serving the airport property is
insufficient to serve additional project development. This impact is potentially significant.
According to the Water Supply Assessment completed for the proposed project, at the
programmatic level of analysis, sufficient water supplies are available to serve its water
demand under normal and dry conditions, including existing and planned land uses, over
the 20-year projection period (Draft EIR Appendix I). This would be accomplished
through the use of one or more of the proposed options, including on-site expansion of
wells for extraction and treatment of additional groundwater, importation of treated
water from Discovery Bay Community Services District (CSD), or importation and on-site
treatment of additional water from Byron-Bethany Irrigation District (BBID). However, as
development under the proposed project proceeds, each of the potential supplies
CPC – March 9, 2022
County File #GP12-0003, DP14-3008 & RZ21-3262
Page 14 of 15
considered would require additional feasibility analysis to determine the actual potential
for project implementation, and would require appropriate agreements (e.g., will-serve
letter) from the off-site suppliers before any development requiring potable water could
be permitted. This process is incorporated into MM-UTIL-1. Connection to either
Discovery Bay CSD or BBID may also conflict with the County’s Urban Limit Line policy,
so on-site expansion of groundwater systems would be the ideal method.
The project site is not connected to public sewer services; instead, the airport relies on
an existing on-site septic system and leach field for its sanitary service. The 2013 Byron
Airport Infrastructure Study considered two potential wastewater generation rates for
bulk warehousing and industrial development: the Central Contra Costa Sanitary
District’s Collection System Master Plan rate of 1,000 gallon per day (gpd) per gross acre,
and the City of Oakland rate of 25 gpd per 1,000 square feet of building square footage.
The Infrastructure Study used the Oakland rate of 25 gpd per 1,000 square feet, resulting
in an estimated 96,000 gpd build-out demand. The development assumptions in the
Infrastructure Study are greater than for the proposed project (146.9 acres and 3,840,000
square feet of building space, compared to 70.9 acres and 941,000 square feet of
building space for the proposed project). Applying the Oakland rate to the proposed
project would result in an estimated wastewater flow of 23,525 gpd. However, the Town
of Discovery Bay, which contains the nearest wastewater treatment plant, uses a
wastewater generation rate of 2,000 gpd per acre of industrial development and 1,600
gpd per acre of commercial development. Using these flow rates, wastewater flow would
be 89,920 gpd for non-aviation uses.
MM-UTIL-2 would require implementation of a wastewater system, per the
recommendations of the Byron Airport Infrastructure Study (Mead & Hunt 2013), which
studied several options for expansion of the on-site sewer system. The options include
requiring each new use or development to provide for its own wastewater disposal, in
effect distributing wastewater treatment to smaller leach fields throughout the site, or
development of centralized treatment though use of an on-site package wastewater
treatment plant and establishment of collection pipelines. For an on-site treatment plant,
effluent disposal may be accomplished through landscape irrigation if the effluent is
treated to a level to meet Title 22 CCR standards. A third option is connection to an
existing sewer system: either the Discovery Bay CSD or the Byron Sanitary District.
Connection to Discovery Bay would involve off-site construction of a force main and
likely modifications to the existing sewage lift station (or a new lift station). Connection
to Byron Sanitary District would likely require an expansion of Byron Sanitary District’s
wastewater treatment facility. Connection to either Discovery Bay or Byron Sanitary
District may also conflict with the County’s Urban Limit Line policy, so on-site expansion
of septic systems and leach fields would be the ideal method.
The proposed project’s requirements would exceed existing water and wastewater
infrastructure, which would have a potentially significant impact without mitigation. The
construction impacts associated with expansion of required infrastructure are addressed
in the Draft and Final EIR and do not represent new significant impacts.

IX. CONCLUSION
The record demonstrates that the Byron Airport Development Program warrants approval.
The project would not threaten the health, safety, and general welfare of the public; it would
improve the economic viability of Byron Airport; it would expand economic opportunities in
East County; and most potentially significant impacts can be mitigated to less-than-
significant levels. Therefore, staff recommends that the County Planning Commission adopt
a motion to make the recommendations listed above in Section II.

Byron Airport opened in 1994
Airport Master Plan updated in 2005
20-year plan to support aviation activities
Identified potential development opportunities on airport property to increase revenue and achieve economic self-sufficiency
Current General Plan policies, zoning regulation, and Airport Land Use Compatibility Plan policies specific to Byron Airport preclude many of the identified land uses.
This proposed project would provide for both additional aviation and new non-aviation development at Byron Airport
Aviation: aircraft storage, admin facilities, instructional facilities, fixed base operators, pilot and passenger terminal improvements, cargo facilities, aircraft service, etc.
Non-aviation: industrial, commercial, and office uses that benefit from proximity to the airport and regional roadway network, such as warehousing, distribution, light manufacturing, research & development, office space, regional retail, commercial service, and local retail and food service.
Objectives
Develop airport facilities to support the types of development
envisioned in the Airport Master Plan and subsequent airport planning
efforts.
Achieve economic self-sufficiency of the airport through the
development of airport-related land uses.
Protect current and future airport operations from incompatible land
uses.
Provide a streamlined planning framework for future development
consistent with the General Plan and the ALUCP.
Proposed Project
General Plan Amendment:
Revise Policies 5-66 and 5-77
Redesignate 11.7-acre parcel from AL to PS
Development Plan Modification:
Current Development Plan would be modified to permit all new uses either by-right or with approval of a land use permit
Also establishes certain development standards, such as maximum building heights, maximum floor area, setbacks, etc.
Rezone
Rezone 11.7-acre parcel from A-3 to P-1
ALUCP Update:
Updated with new policies and maps specific to Byron Airport, which would reflect the 2017 Airport Layout Plan for Byron Airport, the 2005 Byron Airport Master Plan, and guidance set forth in the most recent version of the Caltrans California Airport Land Use Planning Handbook.

PROJECT DESCRIPTION
The project sponsor proposes to develop a phased 144-unit residential subdivision on approximately 78.2-acres of vacant land in the
Martinez/Vine Hill area of unincorporated Contra Costa County. The proposed project includes the following major components on and
adjacent to the project site:
1 A Vesting Tentative Map (VTM) for development of up to 144 detached single-family homes and associated new internal roadways on
approximately 31.8 acres of the project site;
2. Approximately 42 acres of open space, marshes and undeveloped land, including: a) the preservation of approximately 20.1 acres of the
upper hill area shown as “Parcel A” on the VTM; b) the preservation of approximately 19.8 acres of the lower site areas (containing
wetlands, coastal salt marsh, freshwater marsh, open water, and alkali meadow) shown as “Parcel B” on the VTM; c) the development of a
new 2.0-acre stormwater treatment basin, in accordance with the County’s C.3 Guidebook, and shown as “Parcel F” on the VTM;
3. Development of an approximately 4.5-acre private neighborhood park in proximity to “Parcel B” and “Parcel F”;
4. A grading permit for onsite grading of approximately 900,000 cubic yards of earth material for residential subdivision development,
including substantial grading of the lower hill area and limited grading of the upper hill area in order to balance overall project cut and fill
earthwork volumes;
5. Extension of new utility lines to and throughout the project site, and the repair and upgrade of existing off-site utility lines;
6. Improvement of two existing off-site roadways, Central Avenue and Palms Drive, to better accommodate two lanes of moving vehicular
traffic to/from the project site;
7. A tree permit to remove up to 30 code-protected trees;
8. The project also includes requests for exceptions to Title 9 relating to roadway and detention basin standards.
CALIFORNIA ENVIRONMENTAL QUALITY ACT (CEQA)
The Department of Conservation and Development prepared an Environmental Impact Report (EIR) for the project (State Clearinghouse#
2008032074). The project EIR is composed of both a Draft EIR and Final EIR. The Notice of Preparation (NOP) of the EIR was posted on
June 7, 2017 and a public Scoping Meeting was held on July 17, 2017. Both written and oral comments were received during the NOP
public comment period and the Scoping Meeting; the comments were responded to in the Draft EIR, which was released for public review
on May 13, 2021 with a Notice of Availability. A 45-day comment period for the Draft EIR began on May 13, 2021 through June 28, 2021
and was extended at the request of the public for an additional 2 weeks until July 12, 2021. During the comment period, the County
received 21 comment letters on the Draft EIR for the proposed project. The comment topics included concerns about traffic congestion,
views, tree removal, impacts to wildlife, adequacy of emergency services, sanitary and water service, and petroleum pipelines. The County’s
responses to the comments received are provided in the Final EIR that has been prepared for certification by the Board of Supervisors.
The EIR for the proposed project identified two significant and unavoidable effects related to vehicle miles traveled (VMT) for the project,
including:
1. Total Home Based VMT per resident generated by the project would be greater than 15 percent below the regional VMT for similar uses
in Contra Costa County, resulting in a significant impact for the project.
2. The project with a General Plan amendment would increase the Countywide VMT, resulting in a significant impact for the project.
When a public agency determines that a project will have significant and unavoidable effects, Public Resources Code section 21081(b)
requires that the public agency make findings of overriding considerations to demonstrate that economic, legal, social, technological, or
other benefits of the project outweigh the significant environmental effects of the project. Accordingly, the County has made the requisite
findings of overriding consideration and has found that the potential benefits of the project do in fact outweigh the environmental impacts.
The project’s benefits include, Jobs-housing balance, provision of parks and open spaces, new housing inventory, street improvements for
Palms Drive and Central Avenue, and upgraded water and sanitary services, and public nuisance abatement of illegal uses of the project
site. The County’s findings of overriding consideration are attached to this staff report in the project’s findings and proposed conditions of
approval.
STAFF ANALYSIS OF PROJECT
GENERAL PLAN CONSISTENCY
The proposed Bayview Estates Residential Project is consistent with the General Plan. The project sponsor proposes to develop a 144-lot
residential subdivision on approximately 78.3-acres of vacant land. To support the proposed land use and density, the project proposes to
amend the existing Contra Costa County General Plan land use map to change the existing Heavy Industry (HI) land use designation to the
Single-Family Residential-High Density (SH)(5.0-7.2 units/net acre) and Open Space (OS) land use designations. The proposed change of
the land use designation of the project site from HI to SH is compatible with the contiguous existing residential neighborhood to the north
along Palms Drive and Central Avenue, which the General Plan also designates as SH.
The SH designation allows between 5.0 and 7.2 units per net acre. 144 detached single-family homes and associated new internal roadways
and a neighborhood park will be developed on approximately 36.3 acres, and the remaining acreage will comprise open space, wetlands, and
undeveloped land. Subdivision CDSD04-08809, as proposed, includes 144 units on 27.2 net developable acres of the project site. The
density range of the SH land use designation in the General Plan is 5.0 to 7.2 units per net acre, which allows the project site a minimum of
136 units and a maximum of 196 units, which translates to 5.3 units per net acre, and is therefore within the allowable SH density range.
Thus, the proposed project with 144 single-family units is consistent with the SH General Plan designation.
a) General Plan Policies: The application is subject to the General Plan’s “Policies for the Vine Hill/Pacheco Area” (policies 3-105
through 3-107). These policies are highlighted below:
3-105. The scenic assets and unstable slopes of the Vine Hill Ridge are to be protected for open space/agricultural use.
3-106. The residential neighborhood east of I-680 shall be buffered from the industrial/landfill-related uses.
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.
b) Housing Element: The project is also consistent with the following General Plan Housing Element goals and policies.
Goal 1. Maintain and improve the quality of the existing housing stock and residential neighborhoods in Contra Costa County.
Goal 6. Provide adequate sites through appropriate land use and zoning designations to accommodate the County’s share of regional
housing needs.
Goal 9. Promote energy efficient retrofits of existing dwellings and exceeding building code requirements in new construction.
The project site is listed in the housing site inventory that is maintained by the Housing and Community Improvement Division, as a site
suitable for residential development. The project would allow for additional housing opportunities on a vacant underutilized property that
may be developed to meet the housing demands and needs of the County and region. The development of 144 market-rate units on the
property is expected to contribute towards meeting the County’s future 6th Cycle Housing Element Regional Housing Needs Allocation
(RHNA). The 6th Cycle Housing Element covers the planning period from 2023 to 2031 and includes a RHNA of 7,610 housing units as
determined by ABAG/MTC as the unincorporated County’s fair share of development towards the regional housing need. The subject
property is listed in the current 5th Cycle Housing Element sites inventory as available land for the potential development of housing. The
total number of market rate units that the County is responsible for development is 3,133, and this project would provide a significant
contribution towards meeting that goal.
c) Noise Element: The General Plan Noise Element includes the following goals and policies that are applicable to the proposed project:
Goal 11-A. To improve the overall environment in the County by reducing annoying and physically harmful effects of noise for existing
and future residents and for all land uses.
Goal 11-C. To ensure that new developments will be constructed so as to limit the effects of exterior noise on the residents.
Policy 11-1. New projects shall be required to meet acceptable exterior noise level standards as established in the Noise and Land Use
Compatibility Guidelines contained in Figure 11-6. These guidelines, along with the future noise levels shown in the future noise contour
maps, should be used by the County as a guide for evaluating the compatibility of “noise sensitive” projects in potentially noisy areas.
Policy 11-8. Construction activities shall be concentrated during the hours of the day that are not noise-sensitive for adjacent land uses and
should be commissioned to occur during normal work hours of the day to provide relative quiet during the more sensitive evening and early
morning hours.
The Community Noise Exposure Levels on Figure 11-6 of the General Plan Noise Element show that levels of 60 dB or less are normally
acceptable and 70 dB or less are conditionally acceptable for single-family residential land uses. Due to the proximity of Interstate 680
immediately to the east of the project site and the Burlington Northern Santa Fe rail corridor on the southern boundary, future noise levels on
the project site would exceed the 60 dB normally acceptable level for single-family residents and could result in noise impacts on project
residents. Modern construction materials and design techniques generally mitigate such “environment-on-project” impacts to
non-significant levels; therefore, the new residences should not experience excessive noise issues.
With respect to project construction, the project EIR included mitigation measures for avoiding excessive groundborne vibration and
construction noise, by requiring the applicant to create and implement a development-specific noise-reduction plan to reduce noise at
sensitive receptors along Central Avenue to below 75 dBA Lmax. Contractors may elect any combination of legal, non-polluting methods to
maintain or reduce construction-related noise to threshold levels or lower, as long as those methods do not result in other significant
environmental impacts or create a substantial public nuisance. Examples of measures that can effectively reduce noise impacts include
locating equipment in shielded and/or less noise-sensitive areas, selection of equipment that emits low noise levels, and/or installation of
noise barriers such as enclosures to block the line of sight between the noise source and the nearest receptors. Other feasible controls could
include, but shall not be limited to, fan silencers, enclosures, and mechanical equipment screen walls. In addition, the project has been
conditioned to limit construction activities to daytime hours between 8:00 am and 5:00 pm Monday through Friday. The aforementioned
development-specific noise-reduction plan for attenuating construction-related noises shall be implemented prior to the initiation of any
work that triggers the need for such a plan. As conditioned, the proposed project would be consistent with the applicable goals and policies
of the Noise Element.
d) Transportation and Circulation Element:
The Transportation and Circulation Element of the General Plan shows designated arterials and expressways that are part of the County
roadway network. Arthur Road is a southwest-northeast oriented collector and extends from Pacheco Boulevard to a residential area north
of the project site. West of the project site, the roadway has one travel lane in each direction. The I-680/Arthur Road interchanges provides
access to/from points north along I-680.
Central Avenue is a local road with one travel lane in each direction north of the project site. This roadway is maintained by the County
between Arthur Road and Darcie Way and becomes an unpaved private road as it extends to the project site and CCCSD Maltby pump
station. This road would be widened and paved as part of the project, serving as the main access roadway to the project site. The posted
speed limit between Arthur Road and Darcie Way is 25 miles-per hour and has a suggested speed limit of 5 miles-per-hour on the privately
owned segment. Central Avenue currently is not a through street and would serve as a main access roadway to the project site. Palms Drive
is a local road with one travel lane in each direction north of the project site. The surface pavement conditions are poor with uneven and
missing pavement. The road is not a through street and would be extended to the project site as a secondary access. The speed limit is not
posted.
Analysis in the project EIR indicates that the project’s projected trip generation of 1,360 additional daily trips with 107 AM peak hour
vehicle trips and 143 PM peak hour trips would increase traffic volumes on residential roadway segments near the project site resulting in
obstacles (or hazards) for project vehicle traffic. Therefore, in accordance with County requirements and design standards, the project has
been conditioned to mitigate these impacts by providing even surface pavement, appropriate signage, delineation, and other features on
Palms Drive (and Central Avenue if it becomes a public street) to improve vehicle transportation conditions and eliminate obstacles (or
hazards). The project EIR did not find that the project’s traffic volumes would have any substantial congestive effect on the area arterials.
The project EIR did identify that the project would have significant impacts on VMT (“Vehicle Miles Traveled”) for the project. CEQA
Guidelines §15064.3(a) states that VMT “refers to the amount and distance of automobile travel attributable to a project.” These impacts
were analyzed in the EIR based on the project’s effect on VMT and its effects on the pedestrian, bicycle, and transit modes of travel, and it
was found that the total Home-Based VMT per resident generated by the project would be greater than 15 percent below the regional VMT
for similar uses in Contra Costa County, and that the cumulative Countywide VMT would also increase as a result of the project. These
VMT impacts were identified as significant and unavoidable in the EIR. Notwithstanding the significant and unavoidable level of the
project’s impacts on VMT, the project has nonetheless been conditioned to mitigate these impacts the maximum extent feasible by requiring
prior to issuance of building permits for the project applicant to develop a transportation and parking demand management plan (TDM). The
applicant shall submit the TDM program to the County Department of Conservation and Development for review and approval. The TDM
program shall identify trip reduction strategies as well as mechanisms for funding and overseeing the delivery of trip reduction programs
and strategies. The TDM program shall be designed to achieve the trip reduction, as required to reduce the VMT per resident from 20.6 to
16.5, to the extent feasible, consistent with a 20 percent reduction in the near-term. Thus, the project would be consistent with General Plan
transportation policies.
e) Open Space Element:
The Open Space Element of the General Plan contains goals and policies pertinent to the preservation and management of open spaces
within the County. Approximately 44.5 acres of the 78.3-acre project site will be designated open space, natural wetlands, and park areas.
Therefore, the project is consistent with the following goals and policies of the Open Space Element.
Goal 9-A. To preserve and protect the ecological, scenic, cultural/historic, and recreational resource lands of the county.
Goal 9-B. To conserve the open space and natural resources of the county through control of the direction, extent, and timing of urban
growth.
Goal 9-C. To achieve a balance of open space and urban areas to meet the social, environmental, and economic needs of the county now
and for the future.
Policy 9-1. Permanent open space shall be provided within the county for a variety of open space uses.
Policy 9-2. Historic and scenic features, watersheds, natural waterways, and areas important for the maintenance of natural vegetation and
wildlife populations shall be preserved and enhanced.
Policy 9-13. Providing public facilities for outdoor recreation should remain an important land use objective in the county, as a method of
promoting high scenic quality, for air quality maintenance, and to enhance outdoor recreation opportunities of all residents.
Policy 9-21. Any new development shall be encouraged to generally conform with natural contours to avoid excessive grading.
REZONE / ZONING CONSISTENCY
The project site is currently zoned Heavy Industrial District (H-I), which allows heavy industrial manufacturing uses of all kinds, including,
but not limited to, lumber, steel, chemicals, explosives, fertilizers, gas, rubber, paper, cement, sugar, and all other industrial or
manufacturing products including the processing of petroleum and the manufacturing of petroleum products (i.e. crude oil refinery). No
such industrial uses, or other uses of any kind, exist on the subject property which is entirely vacant land. The proposed 144-lot Bay View
Estates Residential Project is incompatible with the current heavy industrial zoning designation. In order to implement the subdivision, the
project includes an application to rezone the subject property (File# CDRZ04-03148) from Heavy Industrial District (H-I) to the Bay View
Estates Planned Unit District (P-1). The P-1 zoning designation will allow single-family homes while setting aside land for hillside open
space, storm drainage management, a neighborhood park, and protected wetlands. Compared to the largely unrestricted development
standards of the Heavy Industrial District, the proposed P-1 district would have reduced lot area, lot width, lot depth, and building height
requirements. The proposed development standards are cited in condition of approval #89.
PLANNING COMMISSION HEARING
PLANNING COMMISSION HEARING
On February 23, 2022, the project was heard by the County Planning Commission (CPC). The CPC opened the hearing, received testimony
from the public and closed the hearing. Comments heard during the CPC hearing included traffic and emergency access concerns. Similar
comments were also previously addressed and responded to in the project EIR. The CPC, with a (6-1) motion, approved the Vesting
Tentative Map (County File# CDSD04-08809) and recommended that the Board of Supervisors approve the General Plan Amendment,
Rezoning, and Preliminary and Final Development Plan for the project. The CPC also certified the project EIR and recommended that the
Board of Supervisors also certify the EIR. There was a 10-day appeal period for the approval of the Vesting Tentative Map, during which
time, one appeal was filed with the County.
APPEAL OF THE PLANNING COMMISSION DECISION
On March 7, 2022, Burt Kallander and Alma Johnson filed a joint appeal (attached) of the Planning Commission's February 23, 2022
decision to approve the Vesting Tentative Map for the project. Enumerated below are the appeal points and staff responses.
Appeal Subject #1
The appellants objected to the remote hearing format, stating that Zoom meetings limit free speech because of technical limitations and the
inability of attendees to interact in-person on the same premises.
Staff Response #1: The remote hearing was held in conformance with all public hearing and Brown Act
requirements. Members of the public were provided the appropriate opportunity to speak on the project
applications and were not restricted in their comments. All public comments were heard and considered by
the Planning Commission.
Appeal Subject #2
The appellants assert that traffic volumes and impacts on Palms Drive were not adequately addressed during project review.
Staff Response #2: The project will be accessed by both Palms Drive and Centra Avenue. Central Avenue would be the main access
roadway to the project site, and Palms Drive would be a secondary access. Palms Drive is a local road with one travel lane in each direction
north of the project site. The road is not a through street and would be extended to the project site as a secondary access. Traffic volumes
were analyzed and it was determined that the project would increase traffic on Palms Drive. Palms Drive could carry an additional 1,360
daily vehicles generated by the project if Central Avenue between Darcie Way and the project site were to remain privately owned. The poor
pavement conditions and narrow travel-way widths on Palms Drive and the private ownership and unpaved condition on Central Avenue
represent obstacles or hazards for project vehicle traffic using Palms Drive and Central Avenue. The project EIR determined that if Central
Avenue remains private, a single public access point on Palms Drive would still operate well for general traffic use when it is improved to
better accommodate two-way traffic movements. The EIR also provided mitigation measures that will reduce traffic impacts on Palms
Drive to less-than-significant levels. Specifically, Mitigation Measure TRF-4 incorporates County requirements and design standards to
provide even surface pavement, appropriate signage, delineation, and other features on Palms Drive (and Central Avenue if it becomes a
public street) that will improve vehicle transportation conditions and eliminate obstacles or hazards.
Appeal Subject #3
The appellants state concerns regarding the adequacy of emergency access to the site.
Staff Response #3: The project would correct existing life-safety deficiencies due to non-compliant emergency vehicle access (EVA),
based on requirements pursuant to the California Fire Code (Fire Code) as amended and adopted by the Contra Costa County Fire
Protection District (Fire District). Currently, Arthur Road is the only road to this Vine Hill neighborhood with over 400 existing homes. The
Fire Code requires two separate fire apparatus access roads. The project would provide a secondary EVA from the south side of the project
site to meet code requirements. Currently, Arthur Road extends into the Vine Hill neighborhood with Central Avenue and Palms Drive
branching off Arthur Road. Both Central Avenue and Palms Drive dead end at the project site. These dead-end roads exceed the maximum
code-prescribed length without a code-prescribed turnaround. The project would extend both Centra Avenue and Palms Drive into the
project site and provide connection between the two roads, as well as provide code-prescribed turnarounds for all in-tract dead-end roads,
all to Fire Code requirements. Currently, segments of the existing Palms Drive have pavement width of less than 20’, and segments of both
Centra Avenue and Palms Drive have damaged and missing pavement. Fire Code requires a minimum clear width of 20’ with pavement
structural section sufficient to sustain fire truck wheel loads. The project would repair and replace existing deficient pavement to meet Fire
Code requirements and, where open space exists, provide for homes with sprinklers and other fire-safety improvements. Accordingly, by
improving Central Avenue and Palms Drive and turning both streets into through streets, by providing a third access road into the
neighborhood, and by replacing open space with residential development equipped with sprinklers, the project will provide a greater level of
emergency vehicle access than the Fire Code requires,and will improve emergency vehicle access for surrounding developments. It should
also be noted that, separately from this project, the adjacent approved Palms 10 subdivision (Tract 8744) would also improve a segment of
Palms Drive adjacent to the project site.
MODIFICATIONS TO FINDINGS AND CONDITIONS OF APPROVAL SUBSEQUENT TO THE
FEBRUARY 23, 2022 CPC HEARING FOR CONSIDERATION BY THE BOARD
FINDINGS
Subsequent to the February 23, 2022 Planning Commission hearing, clarifying edits and additions have been made to the project findings.
These edits were primarily made to the CEQA findings in order provide updated references to direct the reader to the pertinent sections of
the project EIR. No new or substantial project information has been provided that would require public review and comment under CEQA.
Similar clarifying edits have been made to other sections of the findings as well. The revisions are reflected in the final findings in support
of the project attached to this board order.
CONDITIONS OF APPROVAL
Inclusionary Housing
At the February 23, 2022 hearing of the Planning Commission, the Commission requested that the applicants provide affordable housing at
the site. It is important to note that the effective date of the inclusionary unit requirement was November 23, 2006, and the project
applications were deemed complete on October 17, 2006. Because the applications were deemed complete before the effective date of the
ordinance, the project is not subject to the County's Affordable Housing Ordinance that requires at least fifteen percent of the for-sale units
be constructed and sold as inclusionary units (i.e. units that are required to be sold at an affordable sales price to lower and moderate
income households). Staff has engaged the applicant on this issue and the applicant has agreed to provide 5 on-site inclusionary units
affordable to moderate income households, or pay an in-lieu fee, as reflected in the following added condition of approval.
(Condition #114) Inclusionary Housing
(A.) Inclusionary Housing Agreement: Prior to recording the first Final Map or issuance of the first building or grading permit,
whichever occurs first, the developer shall enter into an Inclusionary Housing Agreement for the on-site development and sale of five (5)
inclusionary housing units affordable to moderate income households. Alternatively, the developer may satisfy this condition of approval,
in whole or in part, by payment to the County of an in-lieu fee equal to $100,000 per inclusionary housing unit that the developer elects not
to develop and sell on-site.
(B.) Inclusionary Housing Plan: At least 120 days prior to filing the first Final Map for recordation or submitting an application for
the first building or grading permit, whichever occurs first, the developer shall submit to the County an Inclusionary Housing Plan that
includes the information identified in County Ordinance Code Section 822-4.414. The Inclusionary Housing Plan shall include whether the
developer will satisfy this condition of approval in whole or in part by payment of an in-lieu fee.
(C.) Inclusionary Housing Unit Standards:
1. The project is a phased residential development. The Inclusionary Housing Units shall be constructed in proportion to the construction of
the market-rate units. The parties agree that the phasing schedule for construction of the Inclusionary Housing Units will be as described in
the plan.
2. The Inclusionary Housing Units must be dispersed throughout the residential project. The parties agree that the Inclusionary Housing
Units will be located within the residential project as described in the plan.
3. The Inclusionary Housing Units must have access to all on-site amenities that are available to the market-rate units.
4. The construction quality and exterior design of the Inclusionary Housing Units must be comparable to the market-rate units. However,
the Inclusionary Housing Units may be smaller in size, developed on smaller lots, and have alternative interior finishes.
(D.) Sale of Inclusionary Housing Units:
1. The developer will sell five (5) Inclusionary Housing Units in a condition meeting the reasonable satisfaction of the County and in
accordance with the approved Inclusionary Housing Agreement.
2. The project is a phased residential development. The Inclusionary Housing Units shall be made available for sale in proportion to the sale
of the market rate units. The developer may revise the phasing with the written consent of the County.
3. The initial sale of each Inclusionary Housing Unit must be at a price that does not exceed the affordable sales price to a buyer that is a
moderate-income household. Notwithstanding the foregoing, the maximum affordable sales price may not exceed the appraised value of the
unit.
4. The initial sale of an Inclusionary Housing Unit may occur only to a household that meets the following criteria: a) The household is a
Moderate Income Household; b) The household has not owned a residence within the previous three years; and c) The household has no
more than $250,000 in assets. This amount excludes assets reserved for a down payment and closing costs, assets in retirement savings
accounts, and assets in medical savings accounts.
5. Based on the information provided to the developer by the buyers of the Inclusionary Housing Units, the developer or its third-party
designee will determine the income-eligibility of each buyer of an Inclusionary Housing Unit prior to permitting the buyer to purchase and
occupy the Inclusionary Housing Unit. The developer will submit a completed Income Certification Form to the County not later than 30
days prior to the close of escrow. The developer will retain all records related to income eligibility for at least five years.
6. Developer may independently source qualified buyers for the Inclusionary Housing Units, determine income-eligibility of such buyers,
and complete the Income Certification Form, and/or developer may also hire or utilize one or more third party vendors or brokers to source
qualified buyers for the Inclusionary Housing Units, determine income-eligibility of such buyers, and complete the Income Certification
Form. If necessary, the County agrees to cooperate with such third parties hired by the developer.
7. Prior to the close of escrow for the initial sale of each Inclusionary Housing Unit, Developer shall ensure that the following
documentation is entered into and/or obtained:
a) Appraisal. Developer shall require the buyer to obtain and deliver to developer a third party appraisal obtained by the buyer in connection
with its financing of the purchase of the Inclusionary Housing Unit (or if no appraisal is required, the buyer shall nevertheless obtain a third
party appraisal from a third party appraiser who regularly appraises residential real estate in Contra Costa County for institutional lenders),
which appraisal shall set forth the market value of the Inclusionary Housing Unit as if the Inclusionary Housing Unit were unencumbered
by this Agreement (the "Appraised Market Value"). The Appraised Market Value shall be used in connection with the calculation of
amounts payable to the County under the resale restriction and memorialized by a promissory note and secured by a deed of trust;
b) Resale Restriction. Developer shall ensure that the County and the buyer execute, acknowledge, and deposit into escrow for recordation
against the Inclusionary Housing Unit a resale restriction. The resale restriction shall record immediately after the grant deed conveying the
Inclusionary Housing Unit and before any deed of trust or other instrument securing any financing to the buyer;
c) Promissory Note. Developer shall require the buyer to execute a promissory note in favor of the County that obligates the buyer to pay
the County the amount required under Section 822-4.410(b)(3) of the Ordinance. The promissory note will be subject to County's
reasonable review and approval; and
d) Deed of Trust. Developer shall ensure that the County and the buyer execute, acknowledge, and deposit into escrow for recordation
d) Deed of Trust. Developer shall ensure that the County and the buyer execute, acknowledge, and deposit into escrow for recordation
against the Inclusionary Housing Unit a deed of trust to secure performance of the buyer's covenants under the resale restriction and
payment of the amounts due under the promissory note. The deed of trust shall record immediately after the grant deed conveying the
Inclusionary Housing Unit and concurrent with the resale restriction, subordinate only to the lien for the first mortgage loan obtained by the
buyer to finance the purchase of the Inclusionary Housing Unit.
(E.) Inclusionary Housing Unit Restrictions:
1. In accordance with County Ordinance Code section 822-4.410(b), Inclusionary Housing Units must remain affordable to moderate
income households for the term of affordability. Upon the initial sale of each Inclusionary Housing Unit, the developer will cause
agreements to be recorded in the official records against the Inclusionary Housing Unit. The agreements will stipulate that the Inclusionary
Housing Units are to remain affordable to moderate income households for the term of affordability of not less than 55 years. Each
recorded agreement will be a covenant running with the land, binding on the assigns, heirs, and successors of the developer during the term
of the resale restriction.
2. The buyer's first mortgage amount may not exceed the amount needed to finance the purchase of the Inclusionary Housing Unit and the
buyer's closing costs. The buyer may not refinance any other debt or receive funds at the close of escrow, except to reimburse the buyer for
overpayment of estimated buyer closing costs.
3. The initial purchaser of each Inclusionary Housing Unit must agree to occupy the unit as their principal residence for at least three years
unless an emergency requires the earlier sale of the unit."
The General Plan Amendment findings have also been updated to reflect the voluntary provision by the applicant of inclusionary housing
incentives as being in the public interest and are therefore recommended for approval by the Board of Supervisors.
Community Benefits Agreement (CBA)
The applicant has agreed to enter into the attached CBA with the County. The CBA enhances the project's beneficial contributions to the
community, which supports the County's findings that the proposed General Plan Amendment will be in the public interest. The following
condition of approval has been added by staff:
(Condition #110) CBA The applicant has agreed to enter into a Community Benefits Agreement with the County to fund projects
benefiting the community near the project. The agreement will detail the timing and amount of the agreed-upon community benefit
payments. Prior to filing of the first final map for the project, the applicant shall provide Department of Conservation and Development
staff with evidence that the applicant and County have entered into a Community Benefits Agreement." The General Plan Amendment
findings have also been updated to reflect the community benefits agreement as being in the public interest and are therefore recommended
for approval by the Board of Supervisors.
Trail Access
The applicant has agreed to provide, at the request of the Planning Commission on February 23, 2022, regional and internal trail access as
part of the Bayview Estates Residential Project. The following conditions of approval has been added by staff:
(Condition #111) Regional Trial Easement. The applicant shall record an easement in favor of the County, or other public agency
named by the County, granting public bicycle and pedestrian access on Central Avenue. The purpose is to enable the public to access a
potential future connection to the Iron Horse Trail through a roadway and sidewalk that will be maintained by the HOA. The easement shall
be granted before the first Final Map is recorded.
(Condition #112) Internal Trails. The applicant shall provide internal walking/hiking trail access for Bayview residents for the purpose
of accessing the hill within the development for recreational purposes. Hill access trails will be incorporated into the grading design of the
drainage/erosion control benches. The applicant shall show the trail access on the grading plans and the plans shall be submitted to the
Community Development Division for review prior to approval of site grading permits.
Off-Site Street and Sidewalk Improvements
The applicant has agreed to provide additional off-site street and sidewalk improvements as part of the Bayview Estates Residential Project.
Staff and the appplicant have developed the following condition of approval:
(Condition #113) Enhanced Pedestrian Improvements Along Arthur Road Connecting to Las Juntas Elementary . The
applicant shall design and construct sidewalk and path improvements and enhanced pedestrian crosswalks along Arthur Road and Karen
Lane from the intersection of Arthur Road, Leabig Lane and Palms Drive to and including the pathway from Karen Lane to Las Juntas
Elementary School (collectively, “Enhanced Pedestrian Improvements”). A more precise description of the scope of the Enhanced
Pedestrian improvements is provided in Attachment A to the conditions of approval for the project. The County will review and approve the
project plans to be provided by the applicant. The County will provide the applicant with encroachment permits and all other authorizations
necessary for applicant to construct at no charge to the applicant. The applicant will not have to obtain any Right-of-Way, or permits, or any
regulatory approvals. Applicant will not have to pay for inspections or secure bonds for these improvements. Applicant will assist the
County’s pursuit of any necessary authorizations from Caltrans. The Enhanced Pedestrian Improvements shall be completed prior to the
issuance of the building permit for the 49th home in the project. However, the Director of Conservation and Development may authorize the
issuance of additional building permits pending completion of the Enhanced Pedestrian Improvements if the Director determines, in his or
her sole discretion, that the applicant has made and continues to make a good faith effort towards completion of the Enhanced Pedestrian
Improvements and that the delay in completion is not due to fault of the applicant (e.g., delay in County approvals or required Caltrans
authorizations).
The General Plan Amendment findings have also been updated to reflect that these Off-Street Improvements are in the public interest and
are therefore recommended for approval by the Board of Supervisors. Each of the described conditions of approval are reflected in the final
conditions of approval for the project, attached to this board order.
CONSEQUENCE OF NEGATIVE ACTION:
In the event that the proposed project is not approved, the applicant will not obtain approval of the required General Plan Amendment,
Rezoning, Major Subdivision, and Development Plan entitlements needed to allow development of the proposed 144-unit subdivision
development in the unincorporated Martinez area.
CHILDREN'S IMPACT STATEMENT:

Resolution No. 2022/139
IN THE MATTER OF Approving a General Plan Amendment (County File# CDGP04-00013) for the Bayview Estates Residential Project (144 Lots)
WHEREAS, the Contra Costa County Board of Supervisors held a public hearing on April 26, 2022, to consider the Bayview
Estates Residential Project, proposed in the unincorporated Martinez area. The project includes the certification of the project's
Environmental Impact Report (EIR) and adoption of the mitigation monitoring and reporting program prepared for the project; a
General Plan Amendment (County File# CDGP04-00013); a Rezoning Ordinance (County File# CDRZ04-03148); a Vesting
Tentative Map (County File# CDSD04-08809); and a Preliminary and Final Development Plan (County File# CDDP04-03080).
WHEREAS, the General Plan Amendment for the project reclassifies the site's land use designation from Heavy Industry (HI) to
Single-Family Residential-High Density (SH) and Open Space (OS).
WHEREAS, a resolution is required under Government Code Section 65356 to amend a General Plan.
NOW, THEREFORE, the Contra Costa County Board of Supervisors resolves as follows:
1. The Board of Supervisors makes the following General Plan Amendment (GPA) findings:
a) No change to the County Urban Limit Line (ULL) is proposed. No extension of urban services beyond the ULL is proposed.
The subject site is located entirely within the ULL, and therefore may be designated for “urban” or “non-urban” development, as
defined in the 2005-2020 Contra Costa County General Plan. The proposed land use designations, Single-Family
Residential-High Density (SH) and Open Space (OS) are all allowed;
b) Adoption of the proposed General Plan Amendment will not violate the 65/35 Land Preservation Standard (the “65/35
Standard”), established by county voters through adoption of Measure C-1990 and reaffirmed through adoption of Measure
L-2006. Under the 65/35 Standard, no more than 35 percent of the land in the county may be designated for development with
urban uses and at least 65 percent of the land must be designated for non-urban uses such as agriculture, open space, parks, etc.
The subject site’s existing land use designation is HI. The proposed designations are SH and OS. SH is an urban designation,
while the OS is non-urban, and thus, is consistent with and supports the 65/35 Standard;
c) The current iteration of the Contra Costa County Growth Management Program was established by county voters through
adoption of Measure J-2004. The project complies with the objectives and requirements of the Growth Management Program and
related Contra Costa Transportation Authority (CCTA) resolutions;
d) The County General Plan comprises an integrated, internally consistent, and compatible statement of policies governing land
use in the unincorporated areas of the county. The proposed GPA affects only the Land Use Element Map. Open space would
increase by approximately 46 acres. The proposed change is consistent and compatible with the General Plan’s policies for the
Martinez/Vine Hill area as well as the overarching goals and policies of the General Plan related to land use, growth
management, transportation, housing, noise, conservation, open space, and safety. In no way does amending the project’s land
use plan interfere with the County’s ability to otherwise implement the General Plan. Adoption of the proposed GPA will not
result in an internal inconsistency within the General Plan;
e) Adoption of the proposed GPA is in the public interest. The Bay Area suffers from a severe housing shortage. The proposed
plan for 144 single-family homes avoids many of those impacts and has a higher likelihood of being constructed, thus adding to
the housing stock and helping to alleviate the housing shortage. The project includes the following additional components that
also are in the public interest: 1) the project will contribute to the county's Regional Housing Needs Allocation (RHNA), 2) the
provision of new homes is desirable and will assist to improve the balance between housing and jobs, 3) the project will provide
approximately 46 acres of openspace, parks, and trails, 4) the project would upgrade water and sewer utilities on the area of the
project site, 5) the project will improve street conditions and provide pedestrian facilities on Arthur Road, Palms Avenue, and
Centras Avenue, 6) the project will include a $2,000,000 community benefits agreement, and 7) will provide 5 on-site
inclusionary units affordable to moderate income households, or pay an in-lieu fee.
2. The Board of Supervisors hereby ADOPTS the General Plan Amendment (County File# CDGP04-00013) to reclassify the
land use designation of the subject property from Heavy Industry (HI) to Single-Family Residential-High Density (SH) and
Open Space (OS), and ADOPTS the General Plan Amendment, County File# CDGP04-00013, as part of the first consolidated
General Plan amendment for calendar year 2022, as permitted by State Planning Law.

FINDINGS AND CONDITIONS OF APPROVAL FOR THE BAYVIEW ESTATES
RESIDENTIAL PROJECT; DISCOVERY BUILDERS (APPLICANT & OWNER); COUNTY
FILE #s CDGP04-00013, CDRZ04-03148, CDSD04-08809, CDDP04-03080
A. Growth Management Findings
1. Traffic: The project site is accessed from Palms Drive, an existing private paved
road that links to Arthur Road, a public street 1400 feet to the west; and Central
Avenue, which is a mostly paved public street, but terminates to a private gravel
road some 475 feet west of the project site. Both Palms Drive and Central
Avenue west of the project site currently provide two-way passage but are
generally too narrow to meet current County Public Works standards.
Central Avenue is a local road with one travel lane in each direction north of the
project site. This roadway is maintained by the County between Arthur Road and
Darcie Way and becomes an unpaved private road as it extends to the project
site and CCCSD Maltby pump station. This road would be widened and paved as
part of the project, serving as the main access roadway to the project site. The
posted speed limit between Arthur Road and Darcie Way is 25 miles-per hour
and has a suggested speed limit of 5 miles-per-hour on the privately owned
segment. Central Avenue currently is not a through street and would serve as a
main access roadway to the project site. Palms Drive is a local road with one
travel lane in each direction north of the project site. The surface pavement
conditions are poor with uneven and missing pavement. The road is not a
through street and would be extended to the project site as a secondary access.
Off-site road improvements to Palms Drive and Central Avenue are part of the
overall project scope. The applicant proposes to improve these off-site roadways
to meet the minimum standards necessary to have them accepted by the County
as public streets, and to meet Contra Costa Fire Protection District Code
standards for emergency vehicle accessibility. Analysis in the project EIR indicates
that the project’s projected trip generation of 1,360 additional daily trips with 107
AM peak hour vehicle trips and 143 PM peak hour trips would increase traffic
volumes on residential roadway segments near the project site resulting in
obstacles (or hazards) for project vehicle traffic. Therefore, in accordance with
County requirements and design standards, the project has been conditioned to
mitigate these impacts by providing even surface pavement, appropriate signage,
delineation, and other features on Palms Drive (and Central Avenue if it becomes
a public street) to improve vehicle transportation conditions and eliminate
obstacles (or hazards). The Board of Supervisors incorporates by reference the
findings regarding emergency access and roadways in the Statement of
Overriding Considerations (section H(6)(B) of these Findings). The project EIR did
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 2 of 98
not find that the project’s traffic volumes would have any substantial congestive
effect on the area roadway arterials, and the Transportation Impact Analysis
(Appendix E to the Draft EIR) found that any cumulative congestion effects of the
project in combination with planned local and regional growth is addressed by
the applicant's payment of the County's traffic impact fees.
2. Water: With 144 new residential units, the project would increase demand for
potable water. The project would be served by the Contra Costa Water District
(CCWD). Since the site is undeveloped, the current water demand is zero. For
purposes of sizing water distribution infrastructure and estimating potential
effects to the CCWD’s water supplies, the estimated water demand rate is 148
gallons per capita per day (GPCD), which is the 2020 target in CCWD’s 2015
UWMP. This estimated demand rate is conservative compared to CCWD’s 2015
actual demand rate of 114 GPCD. The project’s 356 new residents would result in
a total water demand of 59 AFY. While this water demand would be an increase
over no existing water usage, it would be offset by the anticipated water demand
if the site were to be developed based on its current land use designation of
Heavy Industrial District.
The CCWD holds entitlements to approximately 213,700 AFY of water. As of 2015,
CCWD’s demand was 119,420 AFY. The project, at approximately 59 AFY, would
represent a 0.05 percent increase over 2015 demand levels. While water demand
would increase as a result of the project, based on the CCWD’s available water
rights and the current level of water demand, it is expected that existing water
supplies would be sufficient to serve the project, and no new or expanded
entitlements would be needed. Also as noted above, the CCWD’s water supply
reliability goal is to meet 100 percent of demand in normal years and a minimum
of 85 percent of demand during a drought. Any potential supply shortfalls
experienced during dry year conditions will be met through a combination of a
short-term conservation program or short-term water purchases (Draft EIR pp.
4.14-12; 2015 CCWD Urban Water Management Plan, p. 1-13; 2020 CCWD Urban
Water Management Plan, p. 1-11). Consistent with the CCWD’s Future Water
Supply Study, a planned purchase of up to 1,700 AF of additional water supply by
2040 is necessary to meet the water supply reliability goal. Although the project
would add to demand in drought years, the increase of the project’s demand on
CCWD’s water supply is negligible and would not be considerable.
3. Sanitary Sewer: The Mt. View Sanitary District (MVSD) has reviewed the
preliminary subdivision and approved of the proposed subdivision as well as the
request to annex the project site to be wholly within the MVSD sphere of
influence, subject to the approval by the LAFCO. MVSD issued a “Will Serve”
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 3 of 98
letter confirming its plan to provide wastewater utility service to the project site.
MVSD is in the process of preparing an updated capacity study that will include
the Bayview project site; the study is expected to be available sometime in 2022.
Final project improvement plans will have to be prepared in accordance with
current MVSD standards and will be evaluated against the updated capacity
study and models. In light of the Will Serve letter issued by MVSD, it is presumed
that the District has sufficient existing capacity to serve the project’s anticipated
wastewater demands, and the project would not result in the construction of new
or expanded wastewater treatment facilities. In-tract wastewater will be
conveyed via gravity sewer lines to the low point at northeast corner of the
development. Sewer will be pumped via a private pump station and through a
force main to the existing sewer in Palms Drive.
4. Fire Protection: According to County General Plan, Fire Protection Policies, the
Fire Department shall strive to reach a maximum running time of 3 minutes
and/or 1.5 miles from the nearest fire station, and new development shall pay its
fair share of costs for new fire protection facilities and services; thus, the project
will pay its fair share for fire protection services.
The project site is located within the service area of the Contra Costa County Fire
Protection District (CCCFPD), one of seven fire protection districts serving the
unincorporated County area. The CCCFPD provides fire and emergency medical
services to a population of nearly one million people in a 304 square-mile District
area, and through mutual aid, in and around the 19 cities and unincorporated
communities of Contra Costa County. including nine cities and unincorporated
areas with 24 fire stations, as well as full service to business and industry,
including several petroleum refineries and chemical manufacturing plants.
The CCCFPD’s service area covers the majority of the central part of the County
and extends from Oakley on the east, Moraga on the south and the cities of
Richmond, Pinole and Hercules on the west. The northern limits of the service
area are defined by the shorelines of Suisun Bay and the Sacramento and San
Joaquin rivers (Contra Costa County, 2020b. The Division maintains 24 fully
staffed stations and more than 400 employees, and 2 more stations staffed with
paid-on-call Reserve Firefighters. Minimum daily staffing is 77 personnel. The 24
on-duty companies are trained and regularly cross-staff numerous specialty
response units including 18 wildland fire apparatus, 3 rescue units, a trench
rescue unit, a fire rescue boat, and a mobile breathing air support unit (CCCFPD,
2020).
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 4 of 98
The CCCFPD provides fire protection and emergency medical aid to the project
site from Fire Stations 9, 13 and 14. Station 9 is located approximately 3 miles
south of the project site at 209 Center Avenue in Pacheco. Station 13 is located
at 251 Church Street in Martinez, and Station 14 is located at 521 Jones Street in
Martinez. Furthermore, the project applicant shall equip all dwelling units with
residential automatic fire sprinkler systems, complying with the 2019 California
Fire Code as adopted by the Contra Costa County Fire Protection District, or
otherwise most current edition, subject to the review and approval of the Contra
Costa County Fire Protection District.
5. Public Protection: The project site would be generally served by Muir Station,
located at 1980 Muir Road in Martinez, approximately 2.5 miles south of the
project site, although calls for Sheriff response may be responded to by
personnel in other Stations within the County. The addition of 144 new residential
dwelling units would result in approximately 356 new residents or approximately
0.04 percent of the Sheriff’s Office countywide service population. Given existing
resources available to service the new development and population on the
project site, it is not anticipated that the project would result in the need for new
physical facilities.
6. Parks and Recreation: The County General Plan Growth Management Element
requires new development to provide 3 acres of neighborhood parkland per 1000
people. The project would result in approximately 356 new residents, which
could increase the demand for existing parks and recreational facilities. The
project includes development of an approximately 4.5-acre private neighborhood
park on the project site, adjacent to the existing freshwater pond and marsh
areas on the site. The proposed park would offer passive activities; no sport
courts, sports fields, or programmed event features would be provided. Bicycle
racks would be provided; however, no vehicular parking is proposed. Moreover,
numerous existing neighborhood and regional parks or other recreational
facilities exist near the project site. Close to the project site are the multi-purpose
trail loop in the Waterbird Regional Preserve (0.5 miles away), the 5-acre Morello
Park (one mile southwest), the 2-acre Holiday Highlands Park (1.1 miles
southwest), and the 4.5-acre Mountain View Park 1.9 acres west – all of which
have a wide range of recreation facilities. Because the proposed new
neighborhood park would be included as part of the project, and given the
existing available facilities, the project would not warrant the construction of
additional new facilities off-site. Additionally, the applicant will be paying the
current park impact and dedication fees for each of the 144 dwelling units.

7. Flood Control and Drainage: Runoff from roofs and paved areas on each of
the 144 lots and the proposed streets would be collected and conveyed directly,
or collected and discharged via the storm drain systems, into the bioretention
treatment facility. The orifice within the outflow structure (located within the most
downstream pond) would slowly meter outflows. After treatment and
hydromodification, outflow from the bioretention area would be directed towards
Pacheco Creek. Overflow would exit the bioretention area through an overflow
outlet structure and, again, be directed towards Pacheco Creek. There is adequate
hydraulic head to allow drainage into, and overflow away from the bioretention
area without need for pumps. The discharge pipe from the outlet structure within
the lowest pond (located in the future park area) would discharge to a dissipator
pad just downstream of the pond to reduce flow energy and then meander its
way to Pacheco Creek. The bioretention area as a whole would be sized,
designed and constructed according to the criteria set in the most current
CCCWP Stormwater C.3 Guidebook.
B. General Plan Amendment Findings
1. Required Finding: Adoption of the proposed General Plan Amendment will
not violate the County Urban Limit Line.
Project Finding: No change to the County Urban Limit Line (ULL) is proposed.
No extension of urban services beyond the ULL is proposed. The subject site is
located entirely within the ULL, and therefore may be designated for “urban” or
“non-urban” development, as defined in the Contra Costa County General Plan.
The proposed land use designations, Single-Family Residential-High Density
(SH) and Open Space (OS), are allowed.
2. Required Finding: Adoption of the proposed General Plan Amendment is
consistent with the 65/35 Land Preservation Standard.
Project Finding: Adoption of the proposed General Plan Amendment (GPA)
will not violate the 65/35 Land Preservation Standard (the “65/35 Standard”),
established by county voters through adoption of Measure C-1990 and
reaffirmed through adoption of Measure L-2006. Under the 65/35 Standard, no
more than 35 percent of the land in the county may be designated for
development with urban uses and at least 65 percent of the land must be
designated for non-urban uses such as agriculture, open space, parks, etc. The
subject site’s existing land use designations is Heavy Industry (HI). The
proposed designations are Single-Family Residential-High Density (SH) and
Open Space (OS). SH is an urban designation, while OS is non-urban.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 6 of 98
Redesignating approximately 44.5 acres from HI to OS will slightly reduce the
percentage of land countywide designated for urban uses.
3. Required Finding: The proposed General Plan Amendment is consistent with
the Contra Costa Transportation Authority Growth Management Program.
Project Finding: The current iteration of the Contra Costa Transportation
Authority (CCTA) Growth Management Program was established by county
voters through adoption of Measure J-2004. The project complies with the
objectives and requirements of the Growth Management Program and related
CCTA resolutions. Analysis of the project’s transportation impacts were
conducted consistent with Measure J growth management guidelines. In
addition, the project Environmental Impact Report was provided to the CCTA
and the Regional Transportation Planning Committee for their review; no
comments or objections to the project were received.
4. Required Finding: Following adoption of the proposed General Plan
Amendment, the General Plan will remain internally consistent, as required
under Government Code Section 65300.5.
Project Finding: The County General Plan comprises an integrated, internally
consistent, and compatible statement of policies governing land use in the
unincorporated areas of the county. The proposed GPA affects only the Land
Use Element Map. The proposed land use designation changes are consistent
and compatible with the General Plan’s policies for the Vine Hill/Pacheco area
as well as the overarching goals and policies of the General Plan related to land
use, growth management, transportation, housing, noise, conservation, open
space, and safety. Amending the Land Use Element Map as proposed does not
interfere with the County’s ability to otherwise implement the General Plan.
Adoption of the proposed GPA will not result in an internal inconsistency within
the General Plan.
5. Required Finding: Adoption of the proposed General Plan Amendment is in
the public interest, as required under Government Code Section 65358(a).
Project Finding: Adoption of the proposed GPA is in the public interest. The
Bay Area suffers from a severe housing shortage. The proposed plan for 144
new single-family homes will add to the housing stock and help to alleviate the
housing shortage in the County. The Housing Element identifies housing quality
as an issue with the County's housing market. More than 60 percent of the
housing stock in unincorporated areas is more than 30 years old, the age when
most homes begin to have major repair or updating needs. (Housing Element,
pp. 6-3 to 6-4.) The project will add 144 new dwelling units to the County's
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 7 of 98
housing market. The project will include a mix of single-story and two-story
houses ranging from 3-5 bedrooms. These homes would be constructed to
modern building codes with enhanced life safety and energy efficiency
components, consistent with County policies and goals. Furthermore, the
current Heavy Industrial zoning and General Plan designations are no longer
practical for the site, since the likelihood of heavy industrial uses being
established on the site, which is immediately adjacent to residential uses, is not
foreseeable given the steepness of the terrain and the access to the site
through the residential areas. Thus, the General Plan Amendment to a
residential designation is in the public interest.
The project includes the following additional components that also are in the
public interest:
• Jobs-Housing Balance. The Housing Element identifies housing quality
as an issue with the County's housing market. More than 60 percent of
the housing stock in unincorporated areas is more than 30 years old,
the age when most homes begin to have major repair or updating
needs. (Housing Element, pp. 6-3 to 6-4.) The project will add 144 new
dwelling units to the County's housing market. The project will include
a mix of single-story and two-story houses ranging from 3-5
bedrooms. These homes would be constructed to modern building
codes with enhanced life safety and energy efficiency components,
consistent with County policies and goals. Furthermore, since there is a
large housing demand in Contra Costa County, and the San Francisco
Bay Area generally, the provision of new homes is desirable and will
assist to improve the balance between housing and jobs. The project
will provide 144 dwelling units near significant employment centers
resulting in public benefits including, reduced congestion, community
identity, and alleviation of pressure to develop less desirable sites since
the project can be considered and in-fill development.
• Contribute to the County's Regional Housing Needs Allocation (RHNA).
The adoption of the GPA is found to be in the public interest as it
would allow for additional housing opportunities on a vacant
underutilized property that may be developed to meet the housing
demands and needs of the County and region. The development of
144 market rate units on the property is expected to contribute
towards meeting the County’s future 6th Cycle Housing Element RHNA.
The 6th Cycle Housing Element covers the planning period from 2023
to 2031 and includes a RHNA of 7,610 housing units as determined by
ABAG/MTC as the unincorporated County’s fair share of development
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 8 of 98
towards the regional housing need. The subject property is listed in the
current 5th Cycle Housing Element sites inventory as available land for
the potential development of housing. The total number of market-rate
units that the County is responsible for development is 3,133, and this
project would provide a significant contribution towards meeting that
goal.
• Parks and Open Spaces. The project will limit the effect of new
residents on existing public park facilities through construction of an
approximately 4.5-acre private neighborhood park (Parcel F). (See
Open Space Element, p. 9-20.) The project includes preservation of
more than 46 acres (approximately 60% of the total project site) as
open space, including hillside meadow open space and wetland, salt
marsh, freshwater marsh, open water, and alkali meadow thereby
preserving the natural beauty as well as habitat value for plants and
wildlife of land that would otherwise be designated for heavy industry
use. In doing so the project contributes to achieving a balance of open
space and urban areas to meet the social, environmental, and
economic needs of the county as envisioned in the General Plan. (Open
Space Element, p. 9-3 [Goal 9-C].) The presence of a local park for
project residents will accommodate inevitable population growth
without significantly impacting demand on public park and recreational
facilities. The project will also include internal walking/hiking trail
access for Bayview residents for the purpose of accessing the hill within
the development for recreational purposes. Additionally, the project
includes the provision of a recorded easement in favor of the County
granting public bicycle and pedestrian access on Central Avenue for
the purpose of enabling the public to access a potential future
connection to the Iron Horse Trail.
• Public Utilities. The project would provide a new 12-inch water
transmission main in off-site locations. As part of this configuration,
the project would extend Contra Costa Water District's ("CCWD")
existing 12-inch transmission main and connect this infrastructure to
CCWD’s existing 6-inch water mains in Central Avenue and Palms Drive.
This infrastructure and these connections will benefit the over 400
homes in the adjacent Vine Hill neighborhoods in the Vine Hill area
and address serious fire flow deficiency (i.e., water flow and pressure
needed for fighting fires) identified by CCWD. The typical fire flow, as
required by the California Fire Code, for a neighborhood of this size is
1500 gallons per minute (gpm) at 20 psi (from two fire hydrants).
CCWD has indicated that existing fire flows of 945 gpm at the current
Bayview Estates Residential Project

terminus of Central Avenue (at the north end of the project site) and
718 gpm at the current terminus of Palm Drive. As a result, the project
will correct a serious existing life-safety deficiency by providing fire
flows of 2,554 gpm and 1,781 gpm at Central Avenue and Palms Drive,
respectively, thereby meeting (or exceeding) minimum required fire
flow requirements.
Mt. View Sanitary District ("MVSD") is the sanitary sewer service
provided for the Vine Hill neighborhoods, and has issued a "Will Serve"
letter for the project. The sanitary sewer from the project will connect
to the existing MVSD sewer system at the existing terminus of Palms
Drive near the north end of the project site. MVSD has indicated that
the existing sewer main (old 6” vitrified clay pipe) in Palms Drive is
deficient because existing pipe material, size, and/or slope do not meet
current MVSD standards. These deficiencies allow for excessive
groundwater and stormwater infiltration and inflows, and also have to
potential to cause blockages and overflows, which could result in
public health issues. The project will replace the Palms Drive sewer
main with 8" polyvinyl chloride pipe meeting current MVSD standards.
As a result, the new sewer main provided by this project will alleviate
the existing sewer problems discussed above.
• Emergency Access. The existing Central Avenue and Palms Drive both
dead end just before the project site and do not provide for emergency
vehicle turnarounds required by the California Fire Code. Additionally,
Arthur Road is the only road to this Vine Hill neighborhood with over
400 existing homes. The project will provide a secondary emergency
vehicle access (EVA) through the south side of the project site,
connecting to the proposed in-tract streets, which then connect to
existing Central Avenue and Palms Drive. The proposed in-tract streets
will also connect Central Avenue and Palms Drive at two locations. As a
result, the project will correct an existing life-safety deficiency by
providing improved EVA access and circulation through a secondary
EVA and Fire Code required emergency vehicle turnarounds. The Board
of Supervisors incorporates by reference the findings regarding
emergency access and roadways in the Statement of Overriding
Considerations (section H(6)(B) of these Findings).
• Roadways. Central Avenue and Palms Drive provide access to the
project site. Central Avenue lacks a continuous sidewalk and its
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 10 of 98
pavement condition over segments not maintained by the County is
poor. Palms Drive is generally a private road. It does not have any
sidewalk and the pavement over its entire length is poor. Palms Drive
at certain locations also does not have a minimum of 20’ of pavement
required by code for fire access. The lack of sidewalk is an existing
hazard for pedestrians. The poor pavement condition is an existing
hazard for motorists, especially emergency vehicles. The project will
construct a continuous sidewalk for Central Avenue and Palms Drive
and repair the deteriorated pavement and widen the pavement where
needed, all to meet current standards and Fire Code. As a result, the
improved Central Avenue and Palms Drive will correct the existing road
hazards.
• Alleviate Public Nuisance. The project site is currently vacant property
with a gate at the Central Avenue entrance. Adjacent residents have
expressed concern about unauthorized activities at or near the site
including dirt bikers trespassing on the vacant site and trash dumping.
These are public nuisance concerns. The project will convert unused
industrial land into needed housing compatible with the adjacent Vine
Hill residential neighborhood. As the project is developed, the existing
public nuisance issues will be abated once the currently vacant site
becomes occupied by homes.
• Community Benefits Agreement. The applicant will enter into a
Community Benefits Agreement and will provide up to $2,000,000 in
financial support to be used for projects within Contra Costa County,
including but not limited to capital, operations and maintenance,
inclusionary housing, open space and parks, streets and utilities, flood
control, etc. This agreement directly supports the general welfare and
interest of the County and its residents through the commitment of
applicant-provided funding.
• Voluntary Provision of Inclusionary Housing. The project has been
conditioned to provide five (5) moderate-income units, or pay an in-
lieu fee of $100,000 per unit.
• Enhanced Pedestrian Improvements Along Arthur Road
Connecting to Las Juntas Elementary. As a condition of the project
intended to augment benefits to the neighboring community, the
applicant will provide sidewalk and path improvements and enhanced
pedestrian crosswalks along Arthur Road and Karen Lane from the
intersection of Arthur Road, Leabig Lane and Palms Drive to and
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 11 of 98
including the pathway from Karen Lane to Las Juntas Elementary
School.
6. Required Finding: Adoption of the proposed General Plan Amendment would
not exceed the limit on such amendments specified under Government Code
Section 65358(b).
Project Finding: Pursuant to Government Code Section 65358(b), no
mandatory element of the General Plan may be amended more than four times
per calendar year. The proposed GPA affects the Land Use Element, a
mandatory element, and is part of the first consolidated amendment of the
Land Use Element for 2022.
C. Rezoning Findings
1. Required Finding: The change proposed will substantially comply with the
general plan.
Project Finding: The project site is currently zoned Heavy Industrial District (H-
I) and is proposed to be rezoned to Planned Unit District (P-1). The proposed
zoning designation (P-1) for the subdivision will be consistent with the new
General Plan land use designations of Single-Family Residential-High Density
(SH) and Open Space (OS). The project sponsor proposes to develop a 144-lot
residential subdivision on approximately 78.3-acres of vacant land. To support
the proposed land use and density, the project proposes to amend the existing
Contra Costa County General Plan land use map to change the existing Heavy
Industry (HI) land use designation to the Single-Family Residential-High Density
(SH)(5.0-7.2 units/net acre) and Open Space (OS) land use designations. The
proposed change of the land use designation of the project site from HI to SH
is compatible with the contiguous existing residential neighborhood to the
north along Palms Drive and Central Avenue, which the General Plan also
designates as SH. The proposal includes 144 units on 27.2 net developable
acres of the project site. The density range of the SH land use designation in the
General Plan is 5.0 to 7.2 units per net acre, which allows the project site a
minimum of 136 units and a maximum of 196 units, which translates to 5.3 units
per net acre, and is therefore within the allowable SH density range. Thus, the
proposed project with 144 single-family units is consistent with the SH General
Plan designation.
2. Required Finding: The uses authorized or proposed in the land use district are
compatible within the district and to uses authorized in adjacent district.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 12 of 98
Project Finding: The project is a residential Planned Unit Development P-1
compatible with and generally and substantially based on the standards
contained under the R-6 Single-Family Residential zoning district, and it
includes open space areas with recreational uses. The project is consistent with
the adjacent residential developments immediately north and contiguous with
the project site, which are predominately R-6 single-family residential
neighborhoods of comparable residential densities.
3. Required Finding: Community need has been demonstrated for the use
proposed, but this does not require demonstration of future financial success.
Project Finding: The project use will provide 144 new housing units that assist
in meeting the housing supply needs identified in the Housing Element of the
General Plan.
D. Findings Required For Approval Of The Tentative Map
The Planning Commission made the following required findings to approve the
Tentative Map on February 23, 2022. The Board of Supervisors concurs with the
following findings.
1. Required Finding: The advisory agency shall not approve a tentative map
unless it finds that the proposed subdivision, together with the provisions for its
design and improvement, is consistent with the applicable general plan
required by law.
Project Finding: The project is consistent with the various elements of the
General Plan, which provides 144 residential units with common and open
space areas. The project is consistent with the new General Plan land use
designations of Single-Family Residential-High Density (SH) and Open Space
(OS) for the project site. The General Plan density range for properties
designated by the SH land use designation is 5.0 to 7.2 units per net acre, which
allows the project site a minimum of 136 units and a maximum of 196 units,
which translates to 5.3 units per net acre, which is consistent with the allowable
SH density range. Furthermore, the project is consistent with the respective
Goals and Policies of the County’s General Plan.
2. Required Finding: The advisory agency shall not approve a tentative map
unless it shall find that the proposed subdivision fulfills construction
requirements.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 13 of 98
Project Finding: As required by the conditions of approval and the Mitigation
Monitoring Reporting Program, the Vesting Tentative Map shall fulfill all
applicable county-imposed construction requirements. The applicant will be
required to comply with all requirements for access and drainage
improvements that have been provided by the Public Works Department as
conditions of approval for the project. Additionally, the applicant will also need
to comply with any construction/development requirements imposed by the
San Ramon Valley Fire Protection District, the Building Inspection Division and
all applicable building codes, the Environmental Health Division, the East Bay
Municipal Utility District, and the Central Contra Costa Sanitary District at the
time of building permit issuance. These agencies were all solicited for their
comments on the proposed subdivision and none has responded indicating an
inability to serve and/or meet the demand. The county geologist determined
that the site is feasible for construction from a geologic standpoint.
On March 7, 2022, two members of the public submitted a joint appeal of the
Planning Commission's February 23, 2022 approval of the Tentative Map. The
appeal objected to the Planning Commission's characterization of the project's
emergency vehicle access and congestion effects. The Board of Supervisors
upholds the Planning Commission's required findings to approve the Tentative
Map and incorporates by reference Finding 1 of the Growth Management
Findings, addressing traffic (section A(1) of these Findings), the findings
regarding zoning (section E(3) of these Findings, the findings regarding
emergency access and roadways in the Statement of Overriding Considerations
(section H(6)(B) of these Findings), and information in the Board of Supervisors'
staff report.
E. Findings of Approval of P-1 Zoning District and Final Development Plan
1. Required Finding: The applicant intends to start construction within two and
one-half years from the effective date of the zoning change and plan approval.
Project Finding: The applicant has indicated that they intend to commence
construction within 2 ½ years off the effective date of the zoning change and
plan approval.
2. Required Finding: The proposed planned unit development is consistent with
the County General Plan.
Project Finding: (See Project Finding C(1) above.)
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 14 of 98
3. Required Finding: In the case of residential development, it will constitute a
residential environment of sustained desirability and stability and will be in
harmony with the character of the surrounding neighborhood and community.
Project Finding: The neighboring residential area consists of single-family
residences, and the project will provide 144 residential units, which is consistent
with the area. According to the Development Plan, the residences will consist of
one or two-story elements with 3-5 bedrooms, and have setbacks similar to the
surrounding properties in the area. Accessory dwelling units and secondary
dwelling units are not part of the Development Plan. The design of the
residences will be reviewed by staff prior to issuance of a building permit.
Overall, the project is similar to the single-family development established in
the surrounding area, although the neighboring residential community has an
older, more varied collection of architectural styles.
4. Required Finding: The development of a harmonious integrated plan justifies
exceptions from the normal application of this code.
Project Finding: The project site has varying terrain consisting of a steep hill in
the northern area of the property, and significant wetland areas that will have to
be avoided and preserved. As a result, residential development on the project
site involves substantial constraints, and these constraints significantly reduce
the buildable portion of the site. Development of the site will involve significant
grading of the hillside, as well as installation of substantial infrastructure to
minimize possible geotechnical issues related to the grading required to
develop 144 residences. In addition, the residential project will need to handle
project-related increases in stormwater runoff.
F. Tree Permit Findings
Required Finding: The Board of Supervisors is satisfied that the following factors as
provided by County Code Section 816-6.8010 for granting a tree permit have been
satisfied:
1. Reasonable development of the property will require the removal of up to 30
trees. Replanting of trees is required, including a restitution for the replanted
trees. All feasible efforts have been made to retain the maximum number of
trees, as well as, to preserve those trees, which are exceptional due to their
visual prominence on the site.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 15 of 98
2. Development of this project cannot be reasonably accommodated on other
parts of the property due to the size of the project site.
G. Findings for Exceptions to Title 9 of the County Ordinance Code for Subdivisions
1. The Public Works Department recommends exceptions to the standards
cited in Sections 98-4.002 (Minimum Requirements) and 92-4.012 (Collector
Streets) and 92-4.056 (Minor Streets).
(1) Required Finding: That there are unusual circumstances or conditions
affecting the property.
Project Finding: The proposed Bayview Estates Subdivision is a 78-acre
144-lot single-family detached residential development. It is on steep terrain
with a hill on the west side and wetlands on the east side. To minimize the
project's environmental impacts by maximizing the preservation of open
space (the hill and wetlands), minimizing grading of the hill and grading into
wetlands, minimizing the development footprint, and implementing Low
Impact Development principles (e.g. minimize impervious surface) per
County's C.3 Guidebook, Applicant has reduced the number of lots from 163
in the original project application to 144 in the current application, and
reduced the development footprint to 32 acres (i.e. 41% of total project
area). The gross density is 1.8 dwelling units per acre (DU/AC). The net
density is 4.5 DU/AC.
(2) Required Finding: The exception is necessary for the preservation and
enjoyment of a substantial property right of the Applicant.
Project Finding: Although Applicant could have enlarged the development
impact footprint beyond the current 32 acres (and thus required more
grading into the hill and wetlands), which would have accommodated more
lots and wider streets, Applicant believes that the currently proposed
project, with fewer lots and narrower right of way widths, strikes a balance
between property rights and protection of environment.
(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: The proposed 50' R/W for in-tract Central Ave. connects
to and is consistent with the off-tract Central Ave., which also has a 50' R/W,
near the northwesterly corner of Bayview. The proposed 50' R/W for in-tract
Palms Dr. connects to and is consistent with the existing off-tract Palms Dr.,
which also has a 50' R/W, near the northwesterly corner of Bayview. The
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 16 of 98
expected Average Daily Traffic (ADT) for each of the in-tract Central Ave.
and Palms Dr. is 680 vehicle trips per day (based on 9.44 per single-family
dwelling, per Institute of Transportation Engineer’s Trip Generation, 10th
Edition). This ADT estimate is conservatively high since vehicle miles traveled
has decreased by approximately 12 percent in California due to COVID
(based on Caltrans Performance Measurement System data for August 2019
and August 2020). Regardless of the actual ADT, 36’ pavement width is too
wide for any two-lane street with fronting homes. Based on other East Bay
communities, residents living on such streets will complain about speeding
when the 85th percentile speed reaches 32 mph or higher. Therefore, from a
traffic engineering perspective, it is suggested a 34’ pavement width for all
through streets within Bayview that are expected to have an ADT of 2,000 or
less. However, it is recognized that 36’ pavement width is needed to
accommodate 20’ fire access with parking on both sides. Cul-de-sac streets
typically don’t have the same speeding issues and can remain at 36’
pavement. On streets that are single loaded such as C Dr., the elimination of
parking on one side due to less parking demand and to allow for the down
sloping bank away from the street to start sooner is acceptable thus
reducing the pavement width to 32’. The proposed 36' pavement width
would provide the required fire access of 20' with parking on both sides
which matches Contra Costa County standard collector pavement
configuration. Given that the proposed R/W width matches existing, the
light traffic volume, and adequate fire access, the proposed exception will
not be detrimental to public welfare.
The proposed 50' R/W for in-tract Minor streets would be consistent with or
wider than similar residential streets in the vicinity. The in-tract Minor streets
would have lighter traffic volumes than the in-tract Collectors.
The proposed 36' pavement width would provide the required fire access of
20' with parking on both sides and be wider than the County Minor Street
required pavement configuration. Given that the proposed R/W width is the
same as the width for an in-tract Collector, the light traffic volumes,
adequate fire access and exceeds County Minor Street pavement width
standard, the proposed exception will not be detrimental to public welfare.
The proposed 44' R/W for C Dr., a collector, would be narrower than the
other two in-tract Collectors (Central Ave. and Palms Dr.). However, C Dr.
with no parking on one side would still provide the required fire access of
20'. This stretch is single loaded with homes on only one side and therefore
won’t require driveway access or public utility service boxes on the side
without the homes which minimize the need to have as much width
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 17 of 98
between the face of curb to the right of way. Given this, the proposed
exception will not be detrimental to public welfare.
With respect to properties in the vicinity of Bayview, no adjacent residents
will need to travel through the Bayview Estates as the project is at the dead-
ends of Central Ave. and Palms Dr. Bayview's in-tract streets will have no
negative effects on properties in the vicinity. Bayview will in fact enhance fire
safety for all residents in the vicinity by extending a 12" watermain from the
south, through Bayview, and connecting to the existing waterlines in Central
Ave. and Palms Dr. This would enhance fire flow capacity for the existing
hydrants and homes in a currently deficient area.
2. The Public Works Department recommends exceptions to the standards
cited in Section 914-12.010 pertaining to the requirement for a detention
basin to be maintained by a public entity in order to allow for the detention
basin in Bayview Estates to be privately maintained by a Homeowners
Association or equivalent private entity with property lien authority.
(1) Required Finding: That there are unusual circumstances or conditions
affecting the property.
Project Finding: The County lacks funding to maintain this detention basin.
(2) Required Finding: The exception is necessary for the preservation and
enjoyment of a substantial property right of the Applicant.
Project Finding: The detention basin is integral to the project and is
required to in order to comply with County drainage and C.3 requirements.
Applicant would not be able to exercise its property rights to develop the
property without the detention basin.
(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: The detention basin is needed to comply with County
drainage and C.3 requirements, which requirements are protective of public
welfare.
H. CEQA FINDINGS
In accordance with CEQA and the CEQA Guidelines, and having received, reviewed,
and considered the environmental impact report (EIR) and other information in the
Record of Proceedings, the County adopts the below findings as part of the project
approval. Pursuant to Public Resources Code Section 21082.1(c)(3), the County also
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 18 of 98
finds that the EIR reflects the County’s independent judgment as the lead agency for
the project.
1. Project Description. The description of the project is described in Chapter 3 of the
environmental impact report for the project. Applicant has also entered into a
Community Benefits Agreement (CBA), attached hereto, and described further in
the Statement of Overriding Considerations. The County has sole discretion on
the use of the CBA funds, including the funding of improvements, which are
separate and independent of the Project approval. The Board of Supervisors
incorporates by reference Finding 3 of the Findings of Approval of P-1 Zoning
District and Final Development Plan regarding the scope of the Project
Development Plan.
3. Environmental Impact Report. The project proposes, a General Plan Amendment
(GPA), and to rezone a vacant 78.2-acre industrially zoned property for single-
family-residential use. The project also includes a phased 144-lot Subdivision
including a Vesting Tentative Map, a Final Development Plan for 144 single-
family residences, a Tree Permit to remove up to 30 code-protected trees, and a
grading permit to grade 900,000 cubic yards of earth material. The Department
of Conservation and Development determined that an environmental impact
report (EIR) was required for the project. Accordingly, the County prepared an EIR
for the project (State Clearinghouse# 2008032074). The project EIR is composed
of both a Draft EIR and Final EIR. The Notice of Preparation of the EIR was posted
on June 7, 2017 and a public Scoping Meeting was held on July 17, 2017. Both
written and oral comments were received during public comment period and the
Scoping Meeting; the comments were responded to in the Draft EIR, which was
released for public review on May 13, 2021 with a Notice of Availability. A 45-day
comment period for the Draft EIR began on May 13, 2021 through June 28, 2021
and extended at the request of the public for an additional 2 weeks until July 12,
2021. During the comment period, the County received 21 comment letters on
the Draft EIR for the proposed project. The comment topics included concerns
about traffic congestion, views, tree removal, impacts to wildlife, adequacy of
emergency services, sanitary and water service, and petroleum pipelines. The
County’s Reponses to the comments received are provided in the Final EIR that
has been prepared for the project.
The Final EIR also includes County-initiated updates and errata to the Draft EIR.
These errata constitute minor text changes to the Draft EIR and occurred in
Section 4.3: Biological Resources, Section 4.6: Greenhouse Gas Emissions and
Energy, Section 4.12: Public Services and Recreation, Section 4.13: Transportation
and Circulation, and Section 4.14: Utilities and Service Systems (see chapter 4 in
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 19 of 98
the Final EIR). The changes were made primarily to correct grammatical and
typographical errors, as well as to improve accuracy and readability of certain
passages. The text changes are not the result of any new significant adverse
environmental impact, and do not alter the effectiveness of any mitigation
included in the pertinent section, and do not alter any findings in the Draft EIR.
The Planning Commission conducted a hearing and certified the EIR for purposes
of the tentative map and recommended approval of the General Plan
Amendment to the Board of Supervisors on February 23, 2022.
For all potentially significant impacts discussed in these findings, the County finds
that the inclusion of certain mitigation measures as part of project approval will
reduce all impacts to a less than significant level. For vehicle miles traveled (VMT)
effects in particular, the County finds that there are two significant and
unavoidable impacts requiring overriding considerations. Therefore, with respect
to the aforementioned VMT impacts only, these CEQA Findings contain a
Statement of Overriding Considerations.
As required by CEQA, the County, concurrent with adopting these CEQA Findings,
also adopts a Mitigation Monitoring and Reporting Program (MMRP) for the
project, included as Appendix A to the Final EIR, and further incorporated as part
of the Condition of Approval for the project. The County finds that this MMRP,
meets the requirements of Public Resources Code Section 21081.6 by providing
for the implementation and monitoring of measures intended to mitigate
potentially significant effects of the project.
For each of the environmental topic areas below, cumulative impacts were
analyzed in the Draft EIR. For all environmental topics discussed in these findings,
any impacts, including cumulative impacts, which were determined to have a less
than significant effect without mitigation are either not discussed or not
discussed at length in these findings, consistent with applicable law. A full
discussion and analysis of all environment impacts, including those found to be
less than significant, are located in Chapter 4 of the Draft EIR and the Final EIR,
and the associated facts and conclusions are incorporated herein by this
reference.
3. Effects Determined to be Less Than Significant. The County finds that, based
upon substantial evidence in the record, the project will not have any significant
effect on Land Use, Plans and Policies or Population and Housing, as detailed in
Chapter 4.9 and Chapter 4.11 of the Draft EIR.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 20 of 98
4. Effects Determined to be Mitigated to Less-Than-Significant Levels. For certain
environmental topics, the Draft EIR identified certain potentially significant effects
that could be mitigated to less-than-significant-levels. These topics are Aesthetics
(detailed in Chapter 4.1 of the Draft EIR), Air Quality (detailed in Chapter 4.2 of
the Draft EIR), Biological Resources (detailed in Chapter 4.3 of the Draft EIR),
Cultural Resources and Tribal Cultural Resources (detailed in Chapter 4.4 of the
Draft EIR), Geology and Soils (detailed in Chapter 4.5 of the Draft EIR),
Greenhouse Gas Emissions and Energy (detailed in Chapter 4.6 of the Draft EIR),
Hazards and Hazardous Materials (detailed in Chapter 4.7 of the Draft EIR),
Hydrology and Water Quality (detailed in Chapter 4.8 of the Draft EIR), Noise
(detailed in Chapter 4.10 of the Draft EIR), Public Service and Recreation (detailed
in Chapter 4.12 of the Draft EIR), Transportation (detailed in Chapter 4.13 of the
Draft EIR), and Utilities and Service Systems (detailed in Chapter 4.14 of the Draft
EIR).
For each of the significant or potentially significant impacts identified in the
above listed sections, changes or alterations have been required or incorporated
into the project, as mitigation measures, which avoid or substantially lessen the
significant effects as identified, with the exception of two significant and
unavoidable Transportation impacts resulting from project VMT, which are
discussed in the next section of these findings. Each of the mitigation measures is
included as part of the Project's MMRP for the project, included as Appendix A to
the Final EIR, and incorporated as part of the Condition of Approval for the
Bayview Estates Residential Project.
Therefore, the County finds that based upon substantial evidence in the record,
mitigations have been required or incorporated into the project which avoid or
substantially lessen the significant effects as identified in the Draft EIR and the
Final EIR, and that no further mitigation is warranted as a matter of fact and as a
matter of law.
The County also makes the following findings regarding certain environmental
topics and mitigation measures in support of the foregoing:
• Aesthetics. The County Board of Supervisors find that there was sufficient
analysis of the impacts of the project on scenic vistas and the visual character
of public views of the site and its surroundings. (Final EIR, pp. 3-332, 19-6,
Draft EIR Chapter 4.1) The views and simulations included in the Draft EIR are
accurate and represent a reasonable depiction of impacts from public
viewpoints, and constitutes substantial evidence to support the Draft EIR's
conclusions. The Draft EIR concluded that the project would not substantially
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 21 of 98
alter the visual character of the site, as viewed from vantage points accessible
by the public, and included photos showing the visual character of the project
site that were representative of public views, as determined by the County’s
professional environmental consultant. (Final EIR, pp. 3-32, 19-9; Draft EIR
Figures 4.1-2, 4.1-3, 4.1-4, 4.1-5.) The County finds, based upon substantial
evidence in the record, that the project as a whole, including the proposed
changes to the existing topography, would not degrade the existing visual
quality of the site or surrounding area, nor would it adversely affect a scenic
view or valuable community resource.
• Biological Resources. The Draft EIR identifies potentially significant impacts to
Creeping Wildrye Grassland. Moore Biological Consultants observed the
grasslands and noted they were of poor quality, having been interspersed
with ruderal grasses and subject to a host of disturbances, and this conclusion
was peer-reviewed by the County's environmental consulting team and
determined to be accurate. Consistent with the Response to Comment No. 2-
6, which is incorporated herein by this reference, the County Board of
Supervisors Finds that Mitigation Measure BIO-5a, developed by the County
based on the evidence and conducted surveys, and is sufficient to mitigate
any potential impacts to the creeping Wildrye Grassland. Use of a significantly
higher mitigation ratio would have no proportion to the potential impacts of
the project.
The Draft EIR also evaluates all direct and indirect impacts on biological
resources from construction and operation of the project, evaluates
cumulative impacts in conjunction with cumulative development in the region,
and identifies and discusses feasible mitigation measures for all potentially
significant impacts. (Final EIR pp. 3-30, 3-110, 3-132-171; Draft EIR pp. 4.3-1 to
4.3-64) The Final EIR adequately addresses, moreover, concerns about
biological species and habitat. (See Final EIR at pp. 3-13 to 3-21) The EIR’s
analysis and conclusions, which were prepared by the County’s expert
consultant, and concurred with by Moore Biological Consultants, determined
the project's operation is unlikely to impact burrowing owls, California black
rails, California Ridgeway’s rails, or salt-marsh harvest mice, since their
presence was not detected on the project site, (Final EIR pp. 3-17; Draft EIR
pp. 4.3-19) and none of the species have a high likelihood of occurrence on
the project site. (Final EIR pp. 3-17; Draft EIR Appendix D, D-14; March 17,
2021, Biological Assessment, pp. 20) The evidence underlying the Final EIR’s
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 22 of 98
project impact analysis on biological resources is adequate, according to the
County's consultants and Moore Biological Consultants; separately and
independently, the project's biological analysis was conducted in compliance
with the California Department of Fish and Wildlife 2012 Staff Report on
Burrowing Owl Mitigation on the subject, incorporated herein by this
reference. (See Final EIR at pp. 3-8)
Based on the concurrence of multiple experts on biological resources, the
conclusions of these consultants, guidance documents from regulatory
agencies, and other evidence in the administrative record of proceedings, the
County finds the conclusions in the Draft EIR and Final EIR are accurate and
supported by substantial evidence.
• Hazards and Hazardous Materials. The Draft EIR identifies a potentially
significant impact resulting from project development where existing crude oil
and natural gas pipelines transect the project site. In analyzing impacts due to
accidental upset of crude oil and natural gas pipelines, the Draft EIR includes a
geotechnical evaluation (the “Milstone report”) that preliminarily concludes
that proposed grading would not damage the pipelines and a risk assessment
of gas pipelines (the “Quest Report”), which concludes the ratio of site
casualties to societal risk and risk of unintentional release to be substantially
less than the significant threshold. (Draft EIR pp. 4.7-6, 4.7-15 to 4.7-17, 4.7-
20; Final EIR pp. 3-4) The Milstone and Quest Reports are incorporated herein
by this reference. In accordance with this evidence, Mitigation Measure HAZ-2
requires accurate mapping of the location of pipelines prior to
commencement of any grading activities and will reduce the risk of damage
to any pipelines in the area. (Draft EIR pp. 4.7-16 to 4.7-17) Furthermore,
Mitigation Measure GEO-2 requires design-level geotechnical report that
would include the engineering analysis for pipeline safety. Both Mitigation
Measure HAZ-2 and Mitigation Measure GEO-2 will reduce potential impacts
resulting from accidental upset to a less than significant level. (Draft EIR, pp.
4.7-16 to 4.7-17; Final EIR pp. 3-4). As a clarification, Mitigation Measure HAZ-
2 will apply to all pipelines on the project site, and shall be clarified as follows:
- Maximum fill heights over all pipelines, including without limitation the
Santa Fe Pacific Partners L.P. (SFPP); Kinder Morgan Energy Partners, L.P
(KMP); and Crimson-Chevron KLM (KLM) and Chevron pipelines shall
not exert a calculated stress of more than what the pipelines can safely

tolerate, as determined by a professional engineer in accord with
applicable industry standards and safety regulations based on
observed pipe material and other factors.
• Transportation. Due to the suppressed travel conditions occurring because of
the COVID-19 pandemic, traditional intersection counts were not used as a
source of data. Instead, Streetlight Data was used to provide a technically
robust baseline of traffic volumes for analysis. (Draft EIR, Appendix E pp. 25)
Trip generation for the Project was based on data published by the Institute
of Transportation Engineers (ITE) Trip Generation Manual (10th Edition), land
use code 210 (single-family detached housing). As shown in the Draft EIR at
Table 4.13-1, the project is estimated to generate 1,360 daily vehicle trip ends
(680 inbound and outbound daily vehicle trips), with about 107 trips during
a.m. peak hour and 143 trips during the p.m. peak hour. (Draft EIR pp. 4.13-6 –
4.13-7) Cameras were not used to estimate existing traffic or predict future
traffic.
• Utilities and Service Systems. The Draft EIR indicates the Mt. View Sanitary
District (MVSD) has sufficient existing capacity to serve the project’s
anticipated wastewater demands and the project would not result in the
construction of new or expanded wastewater treatment facilities. (Draft EIR
pp. 4.14-15 to 4.14-16; Final EIR pp. 3-59, 6-3 to 3-61, 6-10) This is confirmed
by MVSD's issuance of a will-serve letter, that it approved of the proposed
subdivision as well as the request to annex the project site to be within the
MVSD sphere of influence, subject to the approval by the LAFCO (Final EIR pp.
3-59), as well as two reports: a Sanitary Sewer Flow Monitoring & Hydraulic
Modeling Report prepared by Carollo (Final EIR pp. 3-59 to 3-60) and a Sewer
Capacity Study conducted by Aliquot (Final EIR pp. 3-59 to 3-61), which are
part of the EIR and administrative record and incorporated herein by this
reference. These reports and analyses constitute substantial evidence
supporting the conclusion that no impacts to any wastewater treatment plant
would be expected from the project.
5. Project Alternatives. The County hereby concludes that the Draft EIR and Final
EIR set forth a reasonable range of alternatives to the project that address the
significant impacts of the project, so as to foster informed public participation
and informed decision making. The County finds that the alternatives identified
and described in the Draft EIR and Final EIR, the analyses and determinations of
which are incorporated herein by this reference, were considered and further
finds them to be infeasible for the specific economic, social, or other
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 24 of 98
considerations set forth in the EIR and below pursuant to Public Resources Code
section 21081(c).
1) Alternative 1: No Project/ Existing Conditions. Under Alternative 1, the project
would not be constructed, and the 78.3-acre property would remain in its
existing condition: mostly open and undeveloped land. Alternative 1 would
eliminate all project-related impacts. (Draft EIR, pp. 5-3) Full analysis of
Alternative 1 can be found in Chapter 5 of the Draft EIR.
The County rejects Alternative 1 because Alternative 1 would fail to achieve
project objectives, as it would not maximize the development of new
residential projects in the County to help fulfill regional and local (Contra
Costa County) planning goals for the development of housing and would not
introduce new residential uses in areas near employment centers in the Cities
of Martinez, Concord, and Walnut Creek, near existing or planned urban
development, and in areas near regional transportation. (Draft EIR pp. 3-4)
2) Alternative 2: Reduced Grading / 50 percent Development. Alternative 2
considers a reduced impact scenario that would develop the land for less
intense use. In this scenario, the proposed number of housing units would be
reduced by approximately 50 percent to yield a total of 72 new single-family
units, which would be reconfigured on the project site, and would result in a
50% reduction in developable area.
Alternative 2 would not result in any new impacts not identified with the
project, but also would not avoid any of the significant and unavoidable VMT
impacts identified in the project as impacts are calculated on a per capita
basis, as explained in the Draft EIR's Alternatives Chapter. Alternative 2 would
avoid potentially significant greenhouse gas emissions impacts identified for
the project, however, these impacts are already mitigated to a less than
significant level with mitigation measure GHG-1 included in the Mitigation
Monitoring and Reporting Program. (Draft EIR pp. 5-3 to 5-6) Full analysis of
Alternative 2 can be found in Chapter 5 of the Draft EIR.
The County rejects Alternative 2 because Alternative 2 would not avoid any
identified impacts of the project that are not already mitigated to a less than
significant level under the project's Mitigation Monitoring and Reporting
Program.
Moreover, the need for new housing, and the Reduced Density Alternative
would result in the construction of only 72 homes. Pursuant to Government
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 25 of 98
Code section 65583, the County has identified the project site as one of the
specific sites suitable for residential development to fulfill the County's share
of regional housing needs. (Housing Element, pp. 6-71, Table 6-36 [Bayview
Estates to provide 144 above moderate homes toward County RHNA
allocations]; 2014 Land Inventory Appendix A, p. A-4 and Figure 4)
Construction of the project therefore serves important housing policy goals of
increasing housing stock of all types, from lower income to above moderate
income households, and satisfies the County's specific goal of establishing
almost 150 homes on the project site that are necessary to satisfy RHNA
allocations. Critical project objectives here concern the maximization of new
residential projects to fulfill regional and local planning goals for the
development of housing, and to do so near employment centers in the Cities
of Martinez, Concord, and Walnut Creek. (Draft EIR pp. 3-4) Failure to meet
these objectives also signifies a failure to meet important public policies,
including Goal 6 of the County's General Plan Housing Element: "Provide
adequate sites through appropriate land use and zoning designations to
accommodate the County’s share of regional housing needs." (See also
Housing Element Goal 3 and Policy 3.2) Thus, the County rejects Alternative 2
since it would fail to achieve all the project objectives, as it would not achieve
the objective of maximizing the development of new residential projects in
the County to help fulfill regional and local (Contra Costa County) planning
goals for the development of housing. (Draft EIR pp. 3-4)
3) Alternative 3: Reduced Grading/ Light Industrial. Alternative 3 considers
development of light industrial uses, rather than residential and open space
uses, which would not require a zoning reclassification or a change to the
current General Plan land use designation, since light industrial uses are
permitted within existing designations on the project site.
Alternative 3 would involve a wholly different land use necessitating
approximately three on-site employees assumed to reside in the project area,
resulting in a relatively low VMT per weekday. Alternative 3 would still be
expected to result in a significant and unavoidable project VMT impact, but
may avoid the significant and unavoidable contribution to the cumulative
VMT impact identified for the project. (Draft EIR pp. 5-6 to 5-9) Full analysis of
Alternative 3 can be found in Chapter 5 of the DEIR.
The County rejects Alternative 3 because Alternative 3 would fail to achieve
project objectives, as it would not maximize the development of new
residential projects in the County to help fulfill regional and local (Contra
Costa County) planning goals for the development of housing and would not
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 26 of 98
introduce new residential uses in areas near employment centers in the Cities
of Martinez, Concord, and Walnut Creek, near existing or planned urban
development, and in areas near regional transportation. (Draft EIR pp. 3-4)
4) Commercial, Mixed-Use Alternative. The Commercial, Mixed-Use Alternative
would result in fewer homes and fail to meet the project objectives, including
the County's specific goal of establishing almost 150 homes on the project
site that are necessary to satisfy RHNA allocations. At present, the demand for
housing exceeds the demand for commercial uses, and there is the positive
jobs balance in the Martinez sphere of influence. Thus, the County rejects the
Commercial, Mixed-Use Alternative since it would fail to achieve all the
project objectives, as it would not achieve the objective of maximizing the
development of new residential projects in the County to help fulfill region al
and local (Contra Costa County) planning goals for the development of
housing. (DEIR pp. 3-4) This project objective concerns separate and
independent planning policies; this alternative is not feasible.
5) Trail Alternative. Trails will be incorporated into the project's grading, and is
included in the conditions of approval for the project. The hillside already was
intended to include benches for erosion control and drainage along with
access, and therefore incorporation of a trail does not substantially alter the
nature or scope of grading, and thus environmental impacts would be the
same or similar.
6) Environmentally Superior Alternative. The Draft EIR identifies Alternative 3 as
the environmental superior alternative because it avoids a significant and
unavoidable impact of the project that no other analyzed alternative would
avoid (except for the No Project Alternative, which avoids all impacts). As
stated above, the County rejects Alternative 3 because Alternative 3 would fail
to achieve project objectives.
6. Statement of Overriding Considerations. The EIR for the proposed project
identified two significant and unavoidable effects related to vehicle miles traveled
(VMT) for the project, including:
1) Total Home Based VMT per resident generated by the project would be
greater than 15 percent below the regional VMT for similar uses in Contra
Costa County, resulting in a significant impact for the project.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 27 of 98
2) Total Home Based VMT per resident generated by the project would be
greater than 15 percent below the regional VMT for similar uses in Contra
Costa County, resulting in a significant impact for the project.
Contra Costa County is the lead agency under the California Environmental
Quality Act (CEQA) for preparation, review, and certification of the Environmental
Impact Report (EIR) for the Bayview Estates Residential Project. As the lead
agency, the County is also responsible for determining the potential
environmental impacts of the proposed action, which of those impacts are
significant, and which impacts can be mitigated through imposition of feasible
mitigation measures to avoid or minimize such impacts to a level of "less than
significant." When a public agency determines that a project will have significant
and unavoidable effects, Public Resources Code section 21081(b) requires that
the public agency make findings of overriding considerations to demonstrate
that economic, legal, social, technological, or other benefits of the project
outweigh the significant environmental effects of the project. Accordingly, the
County has made the requisite findings of overriding consideration and has
found that the potential benefits of the project do in fact outweigh the
environmental impacts. CEQA requires the lead agency to balance the benefits of
a proposed project against its significant and unavoidable adverse environmental
impacts when determining whether to approve the project. In particular, Public
Resources Code section 21081(a) provides that no public agency may approve or
carry out a project for which an EIR has been certified that identifies one or more
significant effects on the environment that would occur if the project is approved
or carried out, unless the public agency makes one more of three findings with
respect to each significant effect.
When the lead agency approves a project which will result in the occurrence of
significant effects which are identified in the Final EIR, but are not avoided or
substantially lessened, the agency shall state in writing the specific reasons to
support its action based on the Final EIR and/or other information in the record.
The statement of overriding considerations shall be supported by substantial
evidence in the record.
If a lead agency makes a statement of overriding considerations, the statement
should be included in the record of the project approval and should be
mentioned in the notice of determination. The statement of overriding
considerations does not substitute for, and is in addition to, findings required by
CEQA Guidelines section 15091.
A. Summary of Significant Unavoidable Environmental Impacts
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 28 of 98
The Final EIR identified two significant and unavoidable effects related to vehicle
miles traveled ("VMT") for the project, including:
• Impact TRF-3: Total Home Based VMT per resident generated by the
project would be greater than 15 percent below the regional VMT for
similar uses in Contra Costa County, resulting in a significant impact for
the project.
• Impact C-TRF-8: The project with a General Plan amendment would
increase the Countywide VMT, resulting in a significant cumulative impact
for the project.
The following findings and statement of overriding considerations outlines the
specific reasons to support the County's approval of the project.
While the positive jobs balance in the Martinez sphere of influence provides
opportunities for reduced commute distances for the project residents, the Final
EIR discloses that the project's total home-based VMT per resident is 20.6, which
is 4.1 VMT per resident greater than 15 percent below the Contra Costa County
average for residential uses. The County average rate for residential uses is 19.4
VMT per resident, and therefore the pertinent threshold here is 16.5 VMT per
resident. Mitigation Measure TRF-3: Transportation and Parking Demand
Management is proposed to reduce the VMT per resident from 20.6 to 16.5
consistent with a 20 percent reduction in the near-term. Nevertheless, the
requirement to reduce VMT by 20 percent in the near-term using TDM strategies
exceeds the expected level of VMT reduction supported by research, which is
approximately 10 percent. (Final EIR pp. 3-29; July 16, 2021 Response to
Comments Matrix pp. 12-13) Therefore, the level of VMT reduction associated
with TDM measures is unlikely to mitigate the project's impact to a less-than-
significant level, and impacts would be significant and unavoidable.
The Final EIR also discloses that the change in General Plan designation from
Heavy Industry to a Single-Family Residential-High Density (SH) would increase
VMT by 2,731. This comparison is based on the use of a conservative assumption
that heavy industrial uses at the project site would observe a floor area ratio
maximum of 0.1, whereas the General Plan allows up to 0.4 FAR for heavy
industrial uses. Mitigation Measure TRF-3: Transportation and Parking Demand
Management is proposed to reduce the VMT per resident by as much as 10
percent (or about 810 VMT), per the Final EIR. Therefore, the level of VMT
reduction associated with TDM measures is unlikely to mitigate the project's
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 29 of 98
impact to a less-than-significant level, and impacts would be significant and
unavoidable.
The Final DEIR also discloses that an increase in the number of affordable units in
the project would not decrease the project’s significant VMT impact. (Final EIR pp.
3-29) Even with the inclusion of Below Market Rate housing, the maximum
amount of VMT reduction associated with implementation of TDM strategies
available to the project is 10 percent, which is already accomplished by Mitigation
Measure TRF-3: Transportation and Parking Demand Management. (Final EIR pp.
3-29; July 16, 2021 Response to Comments Matrix, pp. 13-14)
The Final EIR also discloses that participation in a Transportation Management
Association or a VMT Banking or Exchange Program to mitigate Project VMT is
not feasible. (Final EIR pp. 3-27 to 3-29; July 16, 2021 Response to Comments
Matrix, pp. 13) Contra Costa County has no Transportation Management
Association, and without such an existing, County-run organization or a County-
wide mandate that other developments must participate in such a program, it is it
is not viable to require the project to participate in a Transportation Management
Association. (Final EIR p. 3-27) CCTA does not currently operate a VMT Banking
or Exchange program and is not expected to operate such a program in the near
future. (Final EIR pp. 3-29)
B. Overriding Considerations
As required under Public Resources Code section 21081 and CEQA Guidelines
section 15093, the County Planning Commission, having reviewed and considered
the project EIR, all other written materials within the administrative record, and all
oral testimony presented at public hearings and other public meetings on the
project EIR, has balanced the benefits of the proposed project against the
identified unavoidable adverse impacts associated with the project, and hereby
adopts all feasible mitigation measures with respect to such impact, certifies the
project EIR, and approves this project.
After balancing the specific economic, legal, social, technological, and other
benefits of the proposed project, the County Planning Commission has
determined that the significant and unavoidable adverse impact related to
project VMT identified above is acceptable due to the following specific
considerations in the record, which outweigh the unavoidable, adverse
environmental impacts of the project. Each of the considerations in the record,
standing alone, is sufficient to support approval of the project, in accordance with
CEQA.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 30 of 98
The project will have the following direct public benefits:
Jobs-housing balance. The Housing Element identifies housing quality as an
issue with the County's housing market. More than 60 percent of the housing
stock in unincorporated areas is more than 30 years old, the age when most
homes begin to have major repair or updating needs. (Housing Element, pp. 6-3
to 6-4.) The project will add 144 new dwelling units to the County's housing
market. The project will include a mix of single-story and two-story houses
ranging from 3-5 bedrooms. These homes would be constructed to modern
building codes with enhanced life safety and energy efficiency components,
consistent with County policies and goals. Furthermore, since there is a large
housing demand in Contra Costa County, and the San Francisco Bay Area
generally, the provision of new homes is desirable and will assist to improve the
balance between housing and jobs. The project will provide 144 dwelling units
near significant employment centers resulting in public benefits including,
reduced congestion, community identity, and alleviation of pressure to develop
less desirable sites since the project can be considered and in-fill development.
• Reduced Congestion: Congestion results in loss of time and productivity,
accidents, personal frustration, increase in pollution, adverse community
reaction and additional adverse safety impacts due to use of residential
streets for commuting purposes. (Transportation and Circulation Element, p.
5-8.) While average VMT for the project would remain above the pertinent
threshold, given that certain project residents will have to commute to San
Francisco and other distant locations, construction of the project means
potentially shorter commute times for a significant portion of the project's
residential population and a corresponding reduction in regional highway
congestion due to nearby employment centers in Martinez, Walnut Creek
and Concord. For example, the project is located in the sphere of influence
of the City of Martinez. Major employers in Martinez include, the County,
Contra-Costa Regional Medical Center, Department of Veterans Affairs,
Kaiser Permanente, Shell Oil Products, and the VA Outpatient Clinic.
(Housing Element, p. 6-14 [Table 6-6].)
• Community Identity: Situating residential development in proximity to
employment centers such as Martinez and other locations where there are
large employers creates the opportunity for common experiences among
project residents, promoting community building and a sense of identity.
• Alleviation of Pressure to Develop Less Desirable Sites: Establishment of a
residential development in an infill location near a major highway, as well as
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 31 of 98
near job centers, alleviates pressure to accommodate homes for the
County's increasing population in less desirable locations, including open
space areas where urban development does not presently exist, and which
are not located in close proximity to major transportation corridors.
Contribute to the County's Regional Housing Needs Allocation (RHNA). The
project would allow for additional housing opportunities on a vacant
underutilized property that may be developed to meet the housing demands and
needs of the County and region. The development of 144 market rate units on
the property is expected to contribute towards meeting the County’s future 6th
Cycle Housing Element RHNA. The 6th Cycle Housing Element covers the
planning period from 2023 to 2031 and includes a RHNA of 7,610 housing units
as determined by ABAG/MTC as the unincorporated County’s fair share of
development towards the regional housing need. The subject property is listed in
the current 5th Cycle Housing Element sites inventory as available land for the
potential development of housing. The total number of market-rate units that the
County is responsible for development is 3,133, and this project would provide a
significant contribution towards meeting that goal.
Community Benefits Agreement. The applicant and County agree to enter into a
Community Benefits Agreement (“CBA”, see attached), which requires funds to be
provided by applicant to the County. County, at its sole discretion, may use these
funds for, among other improvements, sidewalk repairs and related pedestrian
improvements from the intersection of Arthur Road and Palms Drive and Leabig
Lane, to the Las Juntas Elementary School. Said pedestrian improvements are not
a part of the project; would occur separately and independently from the project;
and are exempt from CEQA pursuant to California Code of Regulations Sections
15301 and 15302 (“Class 1 exemption” and “Class 2 exemption”, respectively),
and California Public Resources Code Section 21080.25.
Parks and open spaces. The project will limit the effect of new residents on
existing public park facilities through construction of an approximately 4.5-acre
private neighborhood park (Parcel F). (See Open Space Element, p. 9-20.) The
project includes preservation of more than 46 acres (approximately 60% of the
total project site) as open space, including hillside meadow open space and
wetland, salt marsh, freshwater marsh, open water, and alkali meadow thereby
preserving the natural beauty as well as habitat value for plants and wildlife of
land that would otherwise be designated for heavy industry use. In doing so the
project contributes achieving a balance of open space and urban areas to meet
the social, environmental, and economic needs of the county as envisioned in the
General Plan. (Open Space Element, p. 9-3 [Goal 9-C].) The present of a local park
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 32 of 98
for project residents will accommodate inevitable population growth without
significantly impacting demand on public park and recreational facilities.
Correct Existing Life-Safety Deficiency – Fire Flow. The project would provide a
new 12-inch water transmission main in off-site locations. As part of this
configuration, the project would extend Contra Costa Water District's ("CCWD")
existing 12-inch transmission main and connect this infrastructure to CCWD’s
existing 6-inch water mains in Central Avenue and Palms Drive. This infrastructure
and these connections will benefit the over 400 homes in the adjacent Vine Hill
neighborhoods in the Vine Hill area and address serious fire flow deficiencies (i.e.,
water flow and pressure needed for fighting fires) identified by CCWD. The typical
fire flow, as required by the California Fire Code, as adopted by the Contra Costa
Fire Protection District, for a neighborhood of this size is 1500 gallons per minute
(gpm) at 20 psi (from two fire hydrants). CCWD has indicated that existing fire
flows are of 945 gpm at the current terminus of Central Avenue (at the north end
of the project site) and 718 gpm at the current terminus of Palm Drive. As a
result, the project will correct a serious existing life-safety deficiency by providing
fire flows of 2,554 gpm and 1,781 gpm at Central Avenue and Palms Drive,
respectively according to CCWD's analysis, thereby meeting (or exceeding)
minimum required fire flow requirements.
Sanitary Sewer. Mt. View Sanitary District ("MVSD") is the sanitary sewer service
provided for the Vine Hill neighborhoods, and has issued a "Will Serve" letter for
the project. The sanitary sewer from the project will connect to the existing MVSD
sewer system at the existing terminus of Palms Drive near the north end of the
project site. MVSD has indicated that the existing sewer main (old 6” vitrified clay
pipe) in Palms Drive is deficient because existing pipe material, size, and/or slope
do not meet current MVSD standards. These deficiencies allow for excessive
groundwater and stormwater infiltration and inflows, and also have to potential
to cause blockages and overflows, which could result in public health issues. The
project will replace the Palms Drive sewer main with 8" polyvinyl chloride pipe
meeting current MVSD standards. As a result, the new sewer main provided by
this project will alleviate the existing sewer problems discussed above.
Emergency access. The project would correct existing life-safety deficiencies due
to non-compliant emergency vehicle access (EVA), based on requirements
pursuant to the California Fire Code (Fire Code) as amended and adopted by the
Contra Costa County Fire Protection District (Fire District). Currently, Arthur Road
is the only road to this Vine Hill neighborhood with over 400 existing homes. The
Fire Code requires two separate fire apparatus access roads. The project would
provide a secondary EVA from the south side of the project site to meet code
requirements. Currently, Arthur Road extends into the Vine Hill neighborhood
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 33 of 98
with Central Avenue and Palms Drive branching off Arthur Road. Both Central
Avenue and Palms Drive dead end at the project site. These dead-end roads
exceed the maximum code-prescribed length without a code-prescribed
turnaround. The project would extend both Centra Avenue and Palms Drive into
the project site and provide connection between the two roads, as well as
provide code-prescribed turnarounds for all in-tract dead-end roads, all to Fire
Code requirements. Currently, segments of the existing Palms Drive have
pavement width of less than 20’, and segments of both Centra Avenue and Palms
Drive have damaged and missing pavement. Fire Code requires a minimum clear
width of 20’ with pavement structural section sufficient to sustain fire truck wheel
loads. The project would repair and replace existing deficient pavement to meet
Fire Code requirements and, where open space exists, provide for homes with
sprinklers and other fire-safety improvements. Accordingly, by improving Central
Avenue and Palms Drive and turning both streets into through streets, by
providing a third access road into the neighborhood, and by replacing open
space with residential development equipped with sprinklers, the project will
provide a greater level of emergency vehicle access than the Fire Code requires
and will improve emergency vehicle access for surrounding developments. It
should also be noted that, separately from this project, the adjacent approved
Palms 10 subdivision (Tract 8744) would also improve a segment of Palms Drive
adjacent to the project site.
Roadways. Central Ave and Palms Drive provide access to the project site. Central
Avenue lacks a continuous sidewalk and its pavement condition over segments
not maintained by the County is poor. Palms Drive is generally a private road. It
does not have any sidewalk and the pavement over its entire length is poor.
Palms Drive at certain locations also does not have a minimum of 20’ of
pavement required by code for fire access. The lack of sidewalk is an existing
hazard for pedestrians. The poor pavement condition is an existing hazard for
motorists, especially emergency vehicles. The project will construct a continuous
sidewalk for Central Avenue and also Palms Drive repair the deteriorated
pavement, and widen the pavement where needed, all to meet current standards
and Fire Code. As a result, the improved Central Ave and Palms Drive will correct
the existing road hazards.
Elimination of Public Nuisance. The project site is currently vacant property with a
gate at the Central Avenue entrance. Adjacent residents have expressed concern
about unauthorized activities at or near the site including dirt bikers trespassing
on the vacant site and trash dumping. These are public nuisance concerns. The
project will the project will convert unused industrial land into needed housing
compatible with the adjacent Vine Hill residential neighborhood. As this project is
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080

developed, the existing public nuisance issues will be abated due to the currently
vacant site being occupied by homes.
7. Certification of EIR. On the basis of the whole record before it, including the
EIR, and in accordance with Section 15090, the Board of Supervisors finds that:
• The EIR has been completed in compliance with CEQA;
• The EIR reflects the County’s independent judgement and analysis;
• The EIR was presented to the decision-making body of the Lead Agency
and the decision-making body reviewed and considered the information
contained in the EIR prior to approving the project.
Pursuant to CEQA Section 15097, a Mitigation Monitoring Program has been
prepared, based on the identified impacts and mitigation measures in the EIR.
The Mitigation Monitoring Program is intended to ensure that the mitigation
measures identified in the EIR are implemented. All mitigation measures are
included in the Conditions of Approval for the project.
Recirculation is Not Required
Pursuant to CEQA Guidelines Section 15088.5(a), recirculation of a Draft EIR is
required only if:
“1) a new significant environmental impact would result from the project or
from a new mitigation measure proposed to be implemented;
2) a substantial increase in the severity of an environmental impact would
result unless mitigation measures are adopted that reduce the impact to
a level of insignificance;
3) a feasible project alternative or mitigation measure considerably
different from others previously analyzed would clearly lessen the
environmental impacts of the project, but the project’s proponents
decline to adopt it; or
4) the draft EIR was so fundamentally and basically inadequate and
conclusory in nature that meaningful public review and comment were
precluded.”
None of the text edits or changes to the Draft EIR meet any of the above
conditions. Therefore, recirculation of any part of the Draft EIR is not required.
The information presented in the project EIR support this determination by the
County.
Differences of Opinion Regarding Environmental Analysis
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 35 of 98
In making its determination to certify the EIR and to approve the project, the
Commission recognizes that the project involves controversial environmental
issues and that a range of technical and scientific opinion exists with respect to
those issues. The Commission has acquired an understanding of the range of this
technical and scientific opinion by its review of the Draft EIR, the comments
received on the Draft EIR and the responses to those comments in the Final EIR,
as well as other testimony, letters, and reports submitted for the record. The
Commission recognizes that some of the comments submitted on the EIR, and at
the hearing, disagree with the conclusions, analysis, methodology and factual
bases stated in the EIR. The EIR was prepared by experts, and that some of these
comments were from experts, thus creating a disagreement among experts. The
Commission has reviewed and considered, as a whole, the evidence and analysis
presented in the EIR and in the record, and has gained a comprehensive and
well-rounded understanding of the environmental issues presented by the
project. In turn, this understanding has enabled the Commission to make its
decisions after weighing and considering the various viewpoints on these
important issues.

emissions include the use of late model engines, low -emission
diesel products, alternative fuels, engine retrofit technology,
after-treatment products, add-on devices such as particulate
filters, and/or other options as such are available.
Biological Recourses (BIO-1a): Avoidance and Minimization for Impacts to Special-
Status Plants
23. A qualified botanist with a minimum of four years of academic training and
professional experience in botanical sciences and a minimum of two years of
experience conducting rare plant surveys shall conduct surveys (no more than 5
calendar days prior to construction activities) for special-status plant species with
a moderate or high potential to occur in the project site (i.e., Bolander’s water
hemlock, soft bird’s-beak, Mason’s lilaeopsis, Congdon’s tarplant, small spikerush,
fragrant fritillary, delta tule pea, delta mudwort, and Suisun Marsh aster) in all
suitable habitat that would be potentially disturbed by the project.
24. If no special-status plants are found during focused surveys, the botanist shall
document the findings of found species in a letter to CDFW and the County, and
no further mitigation will be required.
25. If special-status plants are found during focused surveys, the following measures
shall be implemented:
a) Information regarding the special-status plant populations shall be reported
to the CNDDB, mapped, and documented in a technical memorandum
provided to the County.
b) If federally or state listed species are identified during floristic preconstruction
surveys, the project proponent shall mark these plants for avoidance and
comply with applicable laws (i.e., the federal and State Endangered Species
Acts) including through coordination or consultation with regulatory agencies
(i.e., USFWS and/or CDFW), as appropriate, and as described in items d and e,
below.
c) If other special-status plant populations (i.e., California Rare Plant Ranked or
locally significant plants) are identified during floristic preconstruction surveys
and can be avoided during project implementation, they shall be clearly
marked in the field by a qualified botanist and avoided during construction
activities. If a Rank 3 or Rank 4 plant species is detected during the survey, the
survey report shall analyze species rarity consistent with CEQA Guidelines
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 44 of 98
(Section 15380) to determine if species protection is warranted. If the plants
do not warrant protection, then no further action is needed for these species.
d) If special-status plant populations are identified and cannot be avoided, the
project proponent shall coordinate or consult with the County and regulatory
agencies, as appropriate, on relocation of special-status plants. To the extent
feasible, special-status plants that would be impacted by the project shall be
relocated within local suitable habitat. This can be done either through
salvage and transplanting or by collection and propagation of seeds or other
vegetative material. Any plant relocation or reintroduction through seeds or
other vegetative material would be done under the supervision of a qualified
botanist or restoration ecologist.
e) If rare plants can be avoided, prior to vegetation removal, ground clearing or
ground disturbance, all on-site construction personnel shall be instructed as
to the species’ presence and the importance of avoiding impacts to rare plant
species and their habitat though the Worker Environmental Awareness
Program training as described in Mitigation Measure BIO-2a.
f) The project proponent shall prepare a Rare Plan Relocation/Reintroduction
and Monitoring Plan for relocated or reintroduced special-status plants which
shall detail relocation or reintroduction methods or appropriate replacement
ratios (e.g., at least 1:1 based on number of relocated plants or the area
occupied by rare plants, as appropriate for the species) and methods for
implementation (e.g., planting methods, need for supplemental irrigation, or
weed control), success criteria (e.g., greater than 70% survival or ground
coverage following 5 years), monitoring and reporting protocols, and
contingency measures that shall be implemented if the initial mitigation fails
(e.g., replanting to achieve success criteria). The plan shall be developed in
coordination with the appropriate agencies prior to the start of local
construction activities with the objective of providing equal or better habitat
and populations than the impacted area(s). The County shall approve the plan.
g) If special-status plants are relocated from the project or reintroduction of
plants or seed is implemented, the project proponent shall maintain and
monitor the relocation sites and/or restored areas for 5 years following the
completion of construction and restoration activities. The project proponent
shall submit monitoring reports to the County at the completion of
restoration and for 5 years following restoration implementation. Monitoring
reports shall include photo-documentation, planting specifications, a site

layout map, descriptions of materials used, and justification for any deviations
from the mitigation plan.
Biological Recourses (BIO-2a): Worker Environmental Awareness Program
Training
26. A project-specific Worker Environmental Awareness Program (WEAP) training
shall be developed and implemented by a qualified biologist for the project and
attended by all construction personnel prior to beginning work onsite. Typical
credentials for a qualified biologist include a minimum of four years of academic
training and professional experience in biological sciences and related resource
management activities, and a minimum of two years of experience conducting
surveys for each species that may be present within the project area. The training
could consist of a recorded presentation that could be reused for new personnel.
The WEAP training shall generally address but not be limited to the following:
a) Applicable State and federal laws, environmental regulations, project permit
conditions, and penalties for non-compliance.
b) Special-status plant and animal species with potential to occur at or in the
vicinity of the project site, their habitat, the importance of these species and
their habitat, the general measures that are being implemented to conserve
these species as they relate to the project, and the boundaries within which
the project construction shall occur, avoidance measures, and a protocol for
encountering such species including a communication chain.
c) Pre-construction surveys associated with each phase of work.
d) Known sensitive resource areas in the project vicinity that are to be avoided
and/or protected as well as approved project work areas.
e) Best management practices (BMPs) and their location on the project site for
erosion control and/or species exclusion.
Biological Recourses (BIO-2b): General Conservation Measures during Construction
The project proponent shall ensure that the following general measures are
implemented by the contractor during construction to prevent and minimize impacts on
special-status species and sensitive biological resources.
27. Ground disturbance and construction footprints will be minimized to the
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 46 of 98
greatest degree feasible.
28. Vehicles shall observe a 15 mile-per-hour speed limit within the project site.
29. The contractor shall provide closed garbage containers for the disposal of all
food-related trash items. All garbage shall be collected daily from the project site
and placed in a closed container from which garbage shall be removed weekly.
Construction personnel shall not feed or otherwise attract fish or wildlife to the
project site.
30. As necessary, erosion control measures shall be implemented to prevent any soil
or other materials from entering any nearby aquatic habitat. Erosion control
measures shall be installed at work site boundaries adjacent to aquatic habitat to
prevent soil from eroding or falling into the area.
31. Erosion control measures shall be implemented as described in the project
SWPPP. Sediment control measures shall be furnished, constructed, maintained,
and later removed. Plastic monofilament of any kind (including those labeled as
biodegradable, photodegradable, or UV-degradable) shall not be used. Only
natural burlap, coir, or jute wrapped fiber rolls that are certified weed-free shall
be used.
32. All fueling and maintenance of vehicles and equipment and the location of
project staging areas shall occur at least 100 feet from any aquatic habitat and
associated freshwater and saltmarsh vegetation. Spill kits containing cleanup
materials shall be available on-site.
33. No equipment used in support of project implementation (e.g. excavator) shall
enter or cross waters in the project area while water is flowing.
34. Project personnel shall be required to report immediately any harm, injury, or
mortality of a listed species (federal or state) during construction, including
entrapment, to the construction foreman, qualified biologist, or County staff. The
County or their consultant shall provide verbal notification to the USFWS
Endangered Species Office in Sacramento, California, and/or to the local CDFW
warden or biologist (as applicable) within 1 working day of the incident. The
County or their consultant shall follow up with written notification to the
appropriate agencies within 5 working days of the incident. All special-status
species observations shall be recorded on California Natural Diversity Data Base
(CNDDB) field sheets/IPaC and sent to the CDFW/USFWS and by County staff or
their consultant.

Biological Recourses (BIO-2c): Avoidance, Minimization, and Protection Measures
for Sensitive Amphibians and Reptiles
The following conservation measures shall be implemented to minimize or eliminate
potential adverse impacts on California red-legged frog (CRLF) and western pond turtle
(WPT) during project construction.
35. Consistent with the USFWS California Red-legged Frog Survey Protocol, a habitat
assessment shall be prepared and submitted to the USFWS to support their
determination of the species’ potential to occur on site. If the USFWS agrees that
the habitat assessment establishes species absence, or if subsequent protocol-
level surveys requested by the USFWS following their review of the habitat
assessment establish species absence, then no further action shall be needed to
protect this species. In the absence of USFWS coordination, CRLF shall be
presumed present within suitable aquatic habitat on the site and protective
measures described below shall be followed.
36. A qualified biologist shall survey the work sites within 5 calendar days prior to the
onset of construction for CRLF and WPT to determine presence (and life stage) of
these species on the project site. Additionally, a qualified biologist shall conduct a
pre-construction survey of project aquatic habitat for CRLF and WPT immediately
prior to the start of construction activities, beginning with installation of exclusion
fencing. The surveys will consist of walking the project work limits adjacent to
areas where natural habitat is present to ascertain presence of these species (e.g.,
grasslands adjacent to suitable aquatic habitat within the project site).
37. Prior to conducting preconstruction surveys, the qualified biologist shall prepare
a relocation plan that describes the appropriate survey and handling methods for
WPT and identifies nearby relocation sites where individuals would be relocated if
found during the preconstruction surveys. The relocation plan shall be submitted
to CDFW for review prior to the start of construction activities. The animal shall
be relocated to equivalent or better WPT habitat relative to where it was found.
38. A qualified biologist shall monitor installation of exclusion fencing to identify,
capture, and relocate WPT if found, and halt or observe work in the vicinity of
CRLF if encountered onsite. The qualified biologist shall have the authority to
stop construction activities proximate to these species and develop alternative
work practices, in consultation with construction personnel and resource agencies
(as appropriate), if construction activities are likely to affect special‐status species
or other sensitive biological resources. Unless explicitly authorized by the USFWS
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 48 of 98
(e.g., through issuance of a Biological Opinion), CRLF shall not be relocated if
encountered within the project site. Rather CRLF shall be allowed to disperse of
their own volition while all work is halted within 50 feet of individuals. If a CRLF is
not dispersing on its own volition, the qualified biologist shall monitor the frog
while exclusion fence installation or other work continues, as long as they can
ensure the safety of the frog. The qualified biologist shall immediately inform the
construction manager that work should be halted or modified (in the case of a
buffer or non-dispersing individual), if necessary, to avert avoidable take of listed
species. Should egg masses, metamorphs, or tadpoles of CRLF be identified
within project site aquatic habitat during these initial surveys or at any time
during project construction, the USFWS shall be contacted prior to continuation
of work near the discovery. If WPT and/or CRLF are not observed during pre-
construction surveys or installation of the exclusion fence, continued biological
monitoring during construction is not necessary. If either of these species are
observed onsite at any time, the project applicant shall coordinate with USFWS
and /or CDFW as necessary to determine the appropriate measures to avoid
species’ take.
39. The project proponent or its contractors shall install temporary exclusion fencing
around key project boundaries (i.e., at the work limit of aquatic habitat and
associated marsh vegetation to be preserved under the project) and around all
staging and laydown areas to exclude CRLF and WPT from project construction
activities:
• Fencing shall be installed immediately prior to the start of construction
activities under the supervision of a qualified biologist.
• The project applicant or their contractor shall ensure that the temporary
exclusion fencing is continuously maintained until all project construction
activities are completed. Daily fence inspections shall be conducted by the
qualified biologist during the first week of construction. Thereafter, the
qualified biologist may train the contractor to conduct regular inspections
and coordinate findings with the qualified biologist. Similarly, vehicles or
equipment parked overnight at the project staging areas or work areas
shall be inspected for harboring species each morning by the qualified
biologist (or the trained contractor) before they are moved.
• The wildlife exclusion fencing shall be a minimum height of 3 feet above
ground surface, with an additional 4 to 6 inches of fence material buried
such that animals cannot burrow under the fence.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 49 of 98
• The exclusion fence shall not cross the marsh associated with Pacheco
Creek along the south edge of the site or bisect marsh vegetation to allow
wildlife movement to continue through these areas when work is not
occurring.
40. All onsite excavations of a depth of 8 inches or greater shall be either backfilled
at the end of each workday, covered with heavy metal plates, or escape ramps
shall be installed at a 3:1 grade to allow wildlife that fall in a means to escape.
Biological Recourses (BIO-3a): Nesting Bird Protection Measures
41. Project staging, project construction, vegetation removal (e.g., clearing and
grubbing), vegetation management activities requiring heavy equipment, or tree
trimming shall be performed outside of the bird nesting season (February 1st
through August 31st) to avoid impacts to nesting birds; if these activities must be
performed during the nesting bird season, a qualified biologist shall be retained
to conduct a pre-construction survey in the project construction and staging
areas for nesting birds and verify the presence or absence of nesting birds no
more than 5 calendar days prior to construction activities or after any
construction breaks of 5 calendar days or more. Surveys shall be performed for
the project construction and staging areas and suitable habitat within 250 feet of
the project construction and staging areas in order to locate any active passerine
(perching bird) nests and within 500 feet of the project construction and staging
areas to locate any active raptor (birds of prey) nest. If nesting birds and raptors
do not occur within 250 and 500 feet of the project area, respectively, then no
further action is required if construction begins within 5 calendar days.
42. If active nests are located during the pre-construction bird nesting surveys, no-
disturbance buffer zones shall be established around nests, with a buffer size
established by the qualified biologist. Typically, these buffer distances are
between 50 feet and 250 feet for passerines and between 300 feet and 500 feet
for raptors. These distances may be adjusted depending on the level of
surrounding ambient activity and if an obstruction, such as a building or
structure, is within line-of-sight between the nest and construction. Reduced
buffers may be allowed if a full-time qualified biologist is present to monitor the
nest and has authority to halt construction if bird behavior indicates continued
activities could lead to nest failure. Buffered zones shall be avoided during
construction-related activities until young have fledged or the nest is otherwise
abandoned.

Biological Recourses (BIO-3b): Avoid and Minimize Impacts to California Black
Rail and Ridgway’s Rail
43. To minimize or avoid the loss of individual California black rail and Ridgway’s rail,
construction activities, including vegetation management activities requiring
heavy equipment, adjacent to tidal marsh areas (within 500 feet [150 meters] or a
distance determined in coordination with USFWS or CDFW, shall be avoided
during the breeding season from February 1 through August 31.
• If areas within or adjacent to rail habitat cannot be avoided during the breeding
season (February 1 through August 31), protocol-level surveys shall be conducted
no more than 5 calendar days prior to construction activities, or after any
construction breaks of 5 calendar days or more, to determine rail nesting
locations. The surveys will focus on potential habitat that could be disturbed by
construction activities during the breeding season to ensure that rails are not
breeding in these locations. Survey methods for rails will follow the Site-Specific
Protocol for Monitoring Marsh Birds, which was developed for use by USFWS and
partners to improve bay-wide monitoring accuracy by standardizing surveys and
increasing the ability to share data (Wood et al. 2017). Surveys are conducted
during the approximate period of peak detectability, January 15 to March 25 and
are structured to efficiently sample an area in three rounds of surveys by
broadcasting calls of target species during specific periods of each survey round.
Call broadcasting increases the probability of detection compared to passive
surveys when no call broadcasting is employed. This protocol has since been
adopted by Invasive Spartina project (ISP) and Point Blue Conservation Science
to survey Ridgway’s rails at sites throughout San Francisco Bay Estuary. The
survey protocol for Ridgway’s rail is summarized below.
− Previously used survey locations (points) should be used when available to
maintain consistency with past survey results. New survey points should be at
least 200 meters apart along transects in or adjacent to areas representative
of potentially suitable marsh habitat. Points should be located to minimize
disturbances to marsh vegetation. Up to 8 points can be located on a transect.
− At each transect, three surveys (rounds) are to be conducted, with the first
round of surveys initiated between January 15 and February 6, the second
round performed February 7 to February 28, and the third round March 1 to
March 25. Surveys should be spaced at least one week apart and the period
between March 25 to April 15 can be used to complete surveys delayed by
logistical or weather issues. A Federal Endangered Species Act Section
10(a)(1)(A) permit is required to conduct active surveys.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 51 of 98
− Each point on a transect will be surveyed for 10 minutes each round. A
recording of calls available from USFWS is broadcast at each point. The
recording consists of 5 minutes of silence, followed by a 30-second recording
of Ridgway’s rail vocalizations, followed by 30 seconds of silence, followed by
a 30-second recording of California black rail, followed by 3.5 minutes of
silence.
• If no breeding Ridgway’s rails or black rails are detected during surveys, or if their
breeding territories can be avoided by 500 feet (150 meters), then project
activities may proceed at that location.
• If protocol surveys determine that breeding Ridgway’s rails or black rails are
present in the project area, the following measures would apply to project
activities conducted during their breeding season (February 1- August 31):
− A USFWS- and CDFW-approved biologist with experience recognizing
Ridgway’s rail and black rail vocalizations will be on site during construction
activities occurring within 500 feet (150 meters) of suitable rail breeding
habitat.
− If a Ridgway’s rail or black rail vocalizes or flushes within 10 meters, it is
possible that a nest or young are nearby. If an alarmed bird or nest is
detected, work will be stopped, and workers will leave the immediate area
carefully and quickly. An alternate route will be selected that avoids this area,
and the location of the sighting will be recorded to inform future activities in
the area.
− All crews working within 500 feet of aquatic habitats during rail breeding
season will be trained and supervised by a USFWS- and CDFW-approved rail
biologist.
− If any activities will be conducted during the rail breeding season in Ridgway’s
rail- or black rail-occupied marshes, biologists will have maps or GPS locations
of the most current occurrences on the site and will proceed cautiously and
minimize time spent in areas where rails were detected.
• For vegetation management activities in suitable habitat for Ridgway’s rail or
black rail, the following measures will be implemented:
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 52 of 98
− Any herbicides to be used will be EPA-certified for use in/adjacent to aquatic
environments.
− Vegetation management activities will be limited to areas outside of tidal
marsh and non-tidal pickleweed marsh habitats.
Biological Recourses (BIO-4a): Avoidance and Minimization Measures for Salt
Marsh Harvest Mouse
44. A USFWS and CDFW-approved biologist, with knowledge of and experience with
salt marsh harvest mouse habitat requirements, will conduct pre-construction
surveys for the species and identify and mark suitable salt marsh harvest mouse
marsh habitat prior to project initiation.
45. Ground disturbance to suitable salt marsh harvest mouse habitat (including, but
not limited to pickleweed, and emergent salt marsh vegetation including bulrush
and cattails) will be avoided to the extent feasible. Where salt marsh harvest
mouse habitat cannot be avoided - such as for channel excavation, access routes
and grading, or anywhere else that vegetation could be trampled or crushed by
work activities - vegetation will be removed from the ground disturbance work
area plus a 10-foot buffer around the area, as well as any access routes within salt
marsh harvest mouse habitat, utilizing mechanized hand tools or by another
method approved by the USFWS and CDFW. Vegetation height shall be
maintained at or below 5 inches above ground. Vegetation removal in salt marsh
harvest mouse habitat will be conducted under the supervision of the USFWS-
and CDFW-approved biologist.
46. To protect salt marsh harvest mouse from construction-related traffic, access
roads, haul routes, and staging areas within 200 feet of salt marsh harvest mouse
habitat will be bordered by temporary exclusion fencing. The fence should be
made of a smooth material that does not allow salt marsh harvest mouse to
climb or pass through, of a minimum above-ground height of 30 inches, and the
bottom should be buried to a depth of at least 6 inches so that mice cannot crawl
under the fence. Any supports for the salt marsh harvest mouse exclusion fencing
(e.g., t-posts) will be placed on the inside of the project area. The last 5 feet of the
fence shall be angled away from the road to direct wildlife away from the road. A
USFWS- and CDFW-approved biologist with previous salt marsh harvest mouse
experience will be on site during fence installation and will check the fence
alignment prior to vegetation clearing and fence installation to ensure no salt
marsh harvest mice are present.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 53 of 98
47. All construction equipment and materials will be staged on existing roadways and
away from suitable wetland habitats when not in use.
48. Vegetation shall be removed from all non-marsh areas of disturbance (driving
roads, grading and stockpiling areas) to discourage presence of salt marsh
harvest mouse.
49. A USFWS- and CDFW-approved biologist with previous salt marsh harvest mouse
monitoring and/or surveying experience will be on site during construction
activities occurring in suitable habitat. The biologist will document compliance
with the project permit conditions and avoidance and conservation measures.
The USFWS-and CDFW-approved biologist has the authority to stop project
activities if any of the requirements associated with these measures is not being
fulfilled. If salt marsh harvest mouse is observed in the work area, construction
activities will cease in the immediate vicinity of the salt marsh harvest mouse. The
individual will be allowed to leave the area before work is resumed. If the
individual does not move on its own volition, the USFWS-approved biologist
would contact USFWS (and CDFW if appropriate) for further guidance on how to
proceed.
50. If the USFWS- and CDFW-approved biologist has requested work stoppage
because of take of any of the listed species, or if a dead or injured salt marsh
harvest mouse is observed, the USFWS and CDFW will be notified within one day
by email or telephone.
51. For vegetation management activities in suitable habitat for salt marsh harvest
mouse, the following measures shall be implemented:
− Any herbicides to be used will be EPA certified for use in/adjacent to aquatic
environments.
− Work in upland habitat within 100 feet of salt marsh harvest mouse habitat
will be scheduled to avoid extreme high tides when there is potential for salt
marsh harvest mouse to move to higher, drier grounds, such as ruderal and
grassland habitats.
Biological Recourses (BIO-4b): Avoidance and Minimization Measures for Bats
52. No more than 5 calendar days prior to construction activities, a qualified biologist
who is experienced with bat surveying techniques, behavior, roosting habitat, and
identification of local bat species shall conduct a pre-construction habitat
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 54 of 98
assessment of the project site to characterize potential bat habitat and identify
potentially active roost sites. No further action is required if the pre-construction
habitat assessment does not identify bat habitat or signs of potentially active bat
roosts within the project site (e.g., guano, urine staining, dead bats, etc.).
53. If the surveying biologist identifies potential roosting habitat or potentially active
bat roosts within or in the immediate vicinity of the project site, including trees
that could be trimmed or removed under the project, the following measures
shall be implemented:
1) Removal of or disturbance to trees identified as potential bat roosting
habitat or active roosts shall occur when bats are active, approximately
between the periods of March 1 to April 15 and August 15 to October 15, to
the extent feasible. These dates avoid bat maternity roosting season
(approximately April 15 to August 31) and period of winter torpor
(approximately October 15 to February 28).
a. If removal of- or disturbance to trees identified as potential bat
roosting habitat or active roosts during the periods when bats are
active is not feasible, a qualified biologist will conduct pre-construction
surveys within 5 calendar days prior to disturbance to further evaluate
bat activity within the potential habitat or roost site.
b. If active bat roosts are not identified in potential habitat during pre-
construction surveys, no further action is required prior to removal of-
or disturbance to trees within the pre-construction survey area.
c. If active bat roosts or evidence of roosting is identified during pre-
construction surveys, the qualified biologist shall determine, if possible,
the type of roost and species.
i) If special-status bat species or maternity or hibernation roosts are
detected during these surveys, appropriate species- and roost-
specific avoidance and protection measures shall be developed by
the qualified biologist. Such measures may include postponing
the removal of or disturbance to trees, or establishing
exclusionary work buffers while the roost is active. A minimum
100-foot no disturbance buffer shall be established around
special-status species, maternity, or hibernation roosts until the
qualified biologist determines they are no longer active. The size
of the no-disturbance buffer may be adjusted by the qualified
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 55 of 98
biologist, in coordination with CDFW, depending on the species
present, roost type, existing screening around the roost site (such
as dense vegetation), as well as the type of construction activity
that would occur around the roost site, and if construction would
not alter the behavior of the adult or young in a way that would
cause injury or death to those individuals. Active maternity roosts
shall not be disturbed without advance CDFW approval until the
roost disbands at the completion of the maternity roosting season
or otherwise becomes inactive, as determined by the qualified
biologist.
ii) If a common species, non-maternity or hibernation roost (e.g.,
bachelor daytime roost) is identified, disturbance to- or removal
of trees or structures may occur under the supervision of a
qualified biologist as described under 2) below.
2) The qualified biologist shall be present during tree di sturbance or removal if
active non-maternity or hibernation bat roosts or potential roosting habitat
are present. Trees with active non-maternity or hibernation roosts of
common species or potential habitat shall be disturbed or removed only
under clear weather conditions when precipitation is not forecast for three
days and when daytime temperatures are at least 50°F to ensure bats are
active and can abandon any potential roosts as disturbance from the
clearing activities occurs, and when wind speeds are less than 15 mph.
Trimming or removal of trees with active (non-maternity or hibernation) or
potentially active roost sites of common bat species shall follow a two-step
removal process:
a. On the first day of tree removal and under supervision of the qualified
biologist, branches and limbs not containing cavities or fissures in
which bats could roost, shall be cut only using hand tools (e.g.,
chainsaws).
b. On the following day and under the supervision of the qualified
biologist, the remainder of the tree may be removed, either using hand
tools or other equipment (e.g. excavator or backhoe).
c. All felled trees shall remain on the ground for at least 24 hours prior to
chipping, off-site removal, or other processing to allow any bats to
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 56 of 98
escape, or be inspected once felled by the qualified biologist to ensure
no bats remain within the tree and/or branches.
3) Bat roosts that begin during construction are presumed to be unaffected as
long as a similar type of construction activity continues, and no buffer would
be necessary. Direct impacts on bat roosts or take of individual bats will be
avoided.
Biological Recourses (BIO-5a): Salvage and Reintroduction of Creeping Wildrye
Grassland
The following measures shall be implemented prior to construction to avoid or minimize
impacts to creeping wildrye grassland within the project site.
54. A qualified botanist shall identify the boundaries of creeping wildrye grassland
within the project site during the flowering season (between June and July) and
prior to site grading. Boundaries of this sensitive natural community shall be
mapped and flagged for avoidance, if feasible.
55. Where avoidance of this community is infeasible, the perennial grasses shall be
harvested at the appropriate time and under the direction of the qualified
botanist from locations where grading and/or ground disturbance will occur
within the project site.
56. Harvested grasses shall be stored for reintroduction into suitable habitat within
upland portions of the project site that will be preserved as open space.
57. The project applicant shall contract a qualified restoration ecologist to prepare a
Monitoring Plan for relocated / transplanted creeping wildrye grasses within the
project site. The plan shall detail methods and location for relocating or
reintroducing the grasses, success criteria, monitoring methods and maintenance
for successful establishment, reporting protocols, and contingency measures to
be implemented if the initial mitigation fails. The plan shall be developed in
coordination with the appropriate agencies prior to the start of local construction
activities, with the objective of providing equal or better habitat and populations
than the impacted area(s). The recommended success criteria for relocated plants
shall be 1:1 ratio [number of plants established: number of plants impacted] after
two years, unless otherwise specified by CDFW. The plan shall be submitted to
the County and CDFW prior to the start of local construction activities within the
creeping wildrye grassland.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 57 of 98
58. Monitoring reports shall include photo-documentation, planting specifications, a
site layout map, descriptions of materials used, and justification for any
deviations from the monitoring plan.
Biological Recourses (BIO-5b): Enhancement and Creation of Valley Oak Woodland
59. The project applicant shall mitigate for temporary disturbance of oak woodland
in support of the project through restoration or preservation / enhancement /
creation of oak woodland at a ratio of 1:1 (restored/enhanced/preserved area:
impacted area) through one of the following options:
1) Planting replacement trees within the project site on areas of the hill that
will be preserved as open space following development. The project sponsor
shall contract with a qualified restoration ecologist to prepare a Habitat
Mitigation and Monitoring Plan (HMMP) for oak woodland habitat to be
restored as part of the project. The HMMP would be subject to approval by
Contra Costa County. The HMMP shall include a detailed description of
restoration/ enhancement/preservation actions proposed such as a planting
plan, a weed control plan to prevent the spread of invasive and non-native
species within restored areas, and erosion control measures to be installed
around the restored area following mitigation planting to avoid or minimize
sediment runoff throughout the project site; restoration performance criteria
for the restored area that establish success thresholds over a period of 5
years; and proposed monitoring/maintenance program to evaluate the
restoration performance criteria, under which progress of restored areas are
tracked to ensure survival of the mitigation plantings. The program shall
document overall health and vigor of mitigation plantings throughout the
monitoring period and provide recommendations for adaptive management
as needed to ensure the site is successful, according to the established
performance criteria. An annual report documenting the results and
providing recommendations for improvements throughout the year shall be
provided to the County.
In designing the Tree Replacement Plan, the arborist shall review the final
project grading plans to ensure that adequate tree preservation methods,
guidelines, and conditions are in place. The project arborist shall host pre-
demolition meetings with the general contractor and demolition contractor
to determine clearance pruning, stump removal techniques, fencing
placement and, timing to establish a Tree Protection Zone (TPZ). The
arborist shall conduct post-demolition meetings to review and confirm tree
protection fencing for grading and construction. All vehicles, equipment,
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 58 of 98
and storage of job site materials and debris, shall be kept outside of the
TPZ. The arborist shall incorporate standard protocols set forth in the
American National Standards Institute (ANSI) A300 Construction
Management Standard, Part 5 and the International Society of
Arboriculture’s Best Management Practices: Managing Trees During
Construction.
2) Paying an in-lieu fee to a natural resource agency or a non-profit
organization that would use the fees to protect or enhance oak woodland
habitat of the region. If an in-lieu fee is used for mitigation, the amount of
the in-lieu fee shall be determined either by calculating the value of the land
with oak woodland habitat proposed for removal, or by some other
calculation. An alternate calculation shall reflect differences in the quality of
habitat proposed for removal, and may consider the cost of comparable
habitat (fee title or easement) in nearby areas. The amount of the in-lieu fee
and entity receiving the funds shall be subject to review and approval by
Contra Costa County.
Biological Recourses (BIO-6a): Protection of Jurisdictional Wetlands and Other Waters
For project development within or adjacent to state and federal jurisdictional wetlands and
waters, protection measures shall be applied to protect these features. These measures shall
be implemented prior to and throughout all site disturbance and construction activities and
shall include the following:
60. An updated wetland delineation shall be submitted to USACE for verification to
establish the boundaries and current jurisdictional status of the aquatic features
in the site. The verified wetland delineation shall be used to quantify the project
impacts to aquatic resources for permitting purposes.
61. To the maximum extent feasible, project construction activities within or adjacent
to wetlands or waters shall be conducted during the dry season (between June 15
and October 15) and the disturbance footprint shall be minimized in these areas.
62. Stabilize disturbed, exposed slopes immediately upon completion of construction
activities (e.g., following cut and fill activities and installation of bioretention pond
infrastructure) to prevent any soil or other materials from entering aquatic
habitat. Plastic monofilament of any kind (including those labeled as
biodegradable, photodegradable, or UV-degradable) shall not be used. Only
natural burlap, coir, coconut or jute wrapped fiber rolls and mats shall be used.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 59 of 98
63. A protective barrier (fence) shall be erected around any wetlands or waters
designated for complete avoidance in project construction plans and regulatory
permits to isolate it from construction or other ground-disturbing activities.
64. A fencing material meeting the requirements of both water quality protection
and wildlife exclusion may be used. Fences must be properly installed with final
approval by a County representative, including adequate supports or wire
backing for use if windy conditions are anticipated, and with the lower edge
keyed in to the soil to ensure a proper barrier. Signage shall be installed on the
fencing to identify sensitive habitat areas and restrict construction activities.
65. No equipment mobilization, grading, clearing, or storage of vehicles, equipment
or machinery, or similar activity shall occur until a County representative has
inspected and approved the wetland protection fence.
66. The project proponent shall ensure that the temporary fence is continuously
maintained until all construction or other ground-disturbing activities are
completed.
67. Drip pans and/or liners shall be stationed beneath all equipment staged nearby
jurisdictional features overnight to minimize spill of deleterious materials into
jurisdictional waters. Equipment maintenance and refueling in support of project
implementation shall be performed in designated upland staging areas and work
areas, and spill kits shall be available on-site. Maintenance activity and fueling
must occur at least 100 feet from jurisdictional wetlands and other waters or
farther as specified in the project permits and authorizations.
Biological Recourses (BIO-6b): Permits and Compensation for Impacts to Wetlands and
Waters
68. Prior to and throughout site disturbance and construction activities, to offset
unavoidable permanent impacts to approximately 0.02 acres of the side-hill seep
and the fill of less than 0.1 acres for construction of the storm drain outfall along
the bank of Pacheco Creek, the project applicant shall secure the appropriate
permits and provide compensatory mitigation as determined by the regulatory
agencies with jurisdiction over the impacted aquatic resources during the
permitting process. To establish the jurisdictional status of the various aquatic
features in the site, the updated wetland delineation will be submitted to USACE
for verification. The necessary permits will depend on the jurisdictional status of
the features. While the outfall in Pacheco Creek is expected to require permits
from USACE (Nationwide 7), CDFW (1602 Streambed Alteration Agreement), and
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 60 of 98
RWQCB (401 Certification), the permitting scenario of the side-hill seep is less
predictable. It is possible USACE will verify this feature as outside Clean Water Act
jurisdiction due to spatial and hydrological isolation from other Waters of the U.S.
If the seep is verified as non-jurisdictional, the Regional Water Quality Control
Board Water would be expected to issue a Notice of Applicability to authorize its
fill pursuant to Water Quality Order No. 2004-0004-DWQ.
At a minimum, or as determined by the USACE, compensation acreage for
impacted wetlands and waters would meet a 1:1 ratio
(created/restored/enhanced: impacted) to achieve no net loss of aquatic
resources. Compensation may include on-site or off-site creation, restoration, or
enhancement of jurisdictional resources, as determined by the permitting
agencies. On-site or off-site creation/restoration/enhancement plans must be
prepared by a qualified biologist prior to construction, include a planting plan
and planting methods, monitoring and reporting requirements, performance
criteria (e.g., species diversity and vegetative cover thresholds), and maintenance
requirements, and is subject to review and modification by resource agency
permits. Implementation of creation/restoration/enhancement activities by the
project applicant (or permittee) shall occur prior to project impacts, whenever
possible, to avoid temporal loss. On- or off-site
creation/restoration/enhancement sites shall be monitored by the applicant for at
least five years to ensure their success, or as otherwise required by resource
agencies.
Cultural Recourses (CUL-1a): Prehistoric and/or Historic-Period Archaeological
Resources
69. If prehistoric or historic-period archaeological resources are encountered during
project implementation, including ground disturbance associated with project
construction, all construction activities within 100 feet shall halt, and a qualified
archaeologist, defined as an archaeologist meeting the U.S. Secretary of the
Interior’s Professional Qualification Standards for Archeology, shall inspect the
find within 24 hours of discovery and notify the County of their initial assessment.
Prehistoric archaeological materials might include obsidian and chert flaked-
stone tools (e.g., projectile points, knives, scrapers) or toolmaking debris;
culturally darkened soil (“midden”) containing heat-affected rocks, artifacts, or
shellfish remains; and stone milling equipment (e.g., mortars, pestles, handstones,
or milling slabs); and battered stone tools, such as hammerstones and pitted
stones. Historic-period materials might include building or structure footings and
walls, and deposits of metal, glass, and/or ceramic refuse.
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 61 of 98
If the County determines, based on recommendations from a qualified
archaeologist and a Native American representative (if the resource is Native
American-related), that the resource may qualify as a historical resource or
unique archaeological resource (as defined in CEQA Guidelines Section 15064.5)
or a tribal cultural resource (as defined in PRC Section 21080.3), the resource shall
be avoided if feasible. If avoidance is not feasible, the County shall consult with
appropriate Native American tribes (if the resource is Native American-related),
and other appropriate interested parties to determine treatment measures to
avoid, minimize, or mitigate any potential impacts to the resource pursuant to
PRC Section 21083.2, and CEQA Guidelines Section 15126.4. This shall include
documentation of the resource and may include data recovery (according to PRC
Section 21083.2), if deemed appropriate, or other actions such as treating the
resource with culturally appropriate dignity and protecting the cultural character
and integrity of the resource, determined by a qualified professional or California
Native American tribe, as is appropriate (according to PRC Section 21084.3). All
significant cultural materials recovered shall, at the discretion of the consulting
professional, be subject to scientific analysis, professional museum curation, and
documentation according to current professional standards.
In considering any suggested mitigation proposed by the consulting professional
to mitigate impacts to cultural resources, the County shall determine whether
avoidance is feasible in light of factors such as the nature of the find, project
design, costs, and other considerations. If avoidance is infeasible, other
appropriate measures, such as data recovery, shall be instituted. The resource
shall be treated with the appropriate dignity, taking into account the resource’s
historical or cultural value, meaning, and traditional use, as determined by a
qualified professional or California Native American tribe, as is appropriate. Work
may proceed on other parts of the project site while mitigation for cultural
resources is carried out. All significant cultural materials recovered shall, at the
discretion of the consulting professional, be subject to scientific analysis,
professional museum curation, and documentation according to current
professional standards. At the County’s discretion, all work performed by the
consulting professional shall be paid for by the proponent and at the County’s
discretion, the professional may work under contract with the County.
Cultural Recourses (CUL-1b): Discovery or Recognition Human Remains During
Construction Activities
In the event of discovery or recognition of any human remains during construction
activities, the following steps shall be taken:
Bayview Estates Residential Project
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080

(D.) Sale of Inclusionary Housing Units:
1) The developer will sell five (5) Inclusionary Housing Units in a condition
meeting the reasonable satisfaction of the County and in accordance
with the approved Inclusionary Housing Agreement.
2) The project is a phased residential development. The Inclusionary
Housing Units shall be made available for sale in proportion to the sale
of the market rate units. The developer may revise the phasing with the
written consent of the County.
3) The initial sale of each Inclusionary Housing Unit must be at a price that
does not exceed the affordable sales price to a buyer that is a moderate-
income household. Notwithstanding the foregoing, the maximum
affordable sales price may not exceed the appraised value of the unit.

the close of escrow. The developer will retain all records related to
income eligibility for at least five years.
6) Developer may independently source qualified buyers for the
Inclusionary Housing Units, determine income-eligibility of such buyers,
and complete the Income Certification Form, and/or developer may also
hire or utilize one or more third party vendors or brokers to source
qualified buyers for the Inclusionary Housing Units, determine income-
eligibility of such buyers, and complete the Income Certification Form. If
necessary, the County agrees to cooperate with such third parties hired
by the developer.

Housing Unit, Developer shall ensure that the following documentation
is entered into and/or obtained:
i. Appraisal. Developer shall require the buyer to obtain and deliver to
developer a third party appraisal obtained by the buyer in
connection with its financing of the purchase of the Inclusionary
Housing Unit (or if no appraisal is required, the buyer shall
nevertheless obtain a third party appraisal from a third party
appraiser who regularly appraises residential real estate in Contra
Costa County for institutional lenders), which appraisal shall set forth
the market value of the Inclusionary Housing Unit as if the
Inclusionary Housing Unit were unencumbered by this Agreement
(the "Appraised Market Value"). The Appraised Market Value shall be
used in connection with the calculation of amounts payable to the
County under the resale restriction and memorialized by a
promissory note and secured by a deed of trust.
ii. Resale Restriction. Developer shall ensure that the County and the
buyer execute, acknowledge, and deposit into escrow for
recordation against the Inclusionary Housing Unit a resale
restriction. The resale restriction shall record immediately after the
grant deed conveying the Inclusionary Housing Unit and before any
deed of trust or other instrument securing any financing to the
buyer.

deed of trust shall record immediately after the grant deed
conveying the Inclusionary Housing Unit and concurrent with the
resale restriction, subordinate only to the lien for the first mortgage
loan obtained by the buyer to finance the purchase of the
Inclusionary Housing Unit.
(E.) Inclusionary Housing Unit Restrictions:
1) In accordance with County Ordinance Code section 822-4.410(b),
Inclusionary Housing Units must remain affordable to moderate income
households for the term of affordability. Upon the initial sale of each
Inclusionary Housing Unit, the developer will cause agreements to be
recorded in the official records against the Inclusionary Housing Unit.
The agreements will stipulate that the Inclusionary Housing Units are to
remain affordable to moderate income households for the term of
affordability of not less than 55 years. Each recorded agreement will be a
covenant running with the land, binding on the assigns, heirs, and
successors of the developer during the term of the resale restriction.
2) The buyer's first mortgage amount may not exceed the amount needed
to finance the purchase of the Inclusionary Housing Unit and the buyer's
closing costs. The buyer may not refinance any other debt or receive
funds at the close of escrow, except to reimburse the buyer for
overpayment of estimated buyer closing costs.
3) The initial purchaser of each Inclusionary Housing Unit must agree to
occupy the unit as their principal residence for at least three years unless
an emergency requires the earlier sale of the unit.

memorandum provided to the County.
b) If federally or state listed species are identified during floristic
preconstruction surveys, the Project proponent shall mark these
plants for avoidance and comply with applicable laws (i.e., the federal
and State Endangered Species Acts) including through coordination
or consultation with regulatory agencies (i.e., USFWS and/or CDFW),
as appropriate, and as described in items d and e, below.
c) If other special-status plant populations (i.e., California Rare Plant
Ranked or locally significant plants) are identified during floristic
preconstruction surveys and can be avoided during project
implementation, they shall be clearly marked in the field by a qualified
botanist and avoided during construction activities. If a Rank 3 or
Rank 4 plant species is detected during the survey, the survey report
shall analyze species rarity consistent with CEQA Guidelines
(Section 15380) to determine if species protection is warranted. If the
plants do not warrant protection, then no further action is needed for
these species.
d) If special-status plant populations are identified and cannot be
avoided, the Project proponent shall coordinate or consult with the
County and regulatory agencies, as appropriate, on relocation of
special-status plants. To the extent feasible, special-status plants that
would be impacted by the Project shall be relocated within local
suitable habitat. This can be done either through salvage and
transplanting or by collection and propagation of seeds or other
vegetative material. Any plant relocation or reintroduction through
seeds or other vegetative material would be done under the
supervision of a qualified botanist or restoration ecologist.
e) If rare plants can be avoided, prior to vegetation removal, ground
clearing or ground disturbance, all on-site construction personnel
shall be instructed as to the species’ presence and the importance of
avoiding impacts to rare plant species and their habitat though the
Worker Environmental Awareness Program training (see Mitigation
Measure BIO-2a, below).

Mitigation Measure BIO-2b: General Conservation Measures during
Construction. The County shall ensure that the following general measures
are implemented by the contractor during construction to prevent and minimize
impacts on special-status species and sensitive biological resources:
1) Ground disturbance and construction footprints will be minimized to
the greatest degree feasible.
2) Project-related Vehicles shall observe a 15 mile-per-hour speed limit
within the Project site.
3) The contractor shall provide closed garbage containers for the
disposal of all food-related trash items. All garbage shall be collected
daily from the Project site and placed in a closed container from
which garbage shall be removed weekly. Construction personnel
shall not feed or otherwise attract fish or wildlife to the Project site.
4) As necessary, erosion control measures shall be implemented to
prevent any soil or other materials from entering any nearby aquatic
habitat. Erosion control measures shall be installed at work site
boundaries adjacent to aquatic habitat to prevent soil from eroding or
falling into the area.
5) Erosion control measures shall be implemented as described in the
Project SWPPP. Sediment control measures shall be furnished,

qualified biologist, or County staff. The County or their consultant
shall provide verbal notification to the USFWS Endangered Species
Office in Sacramento, California, and/or to the local CDFW warden or
biologist (as applicable) within 1 working day of the incident. The
County or their consultant shall follow up with written notification to
the appropriate agencies within 5 working days of the incident. All
special-status species observations shall be recorded on California
Natural Diversity Data Base (CNDDB) field sheets/IPaC and sent to
the CDFW/USFWS and by County staff or their consultant.
Mitigation Measure BIO-2c: Avoidance, Minimization, and Protection
Measures for Sensitive Amphibians and Reptiles. The following
conservation measures shall be implemented to minimize or eliminate potential
adverse impacts on California red-legged frog (CRLF)and western pond turtle
(WPT) during Project construction:
1) Consistent with the USFWS California Red-legged Frog Survey
Protocol, a habitat assessment shall be prepared and submitted to
the USFWS to support their determination of the species’ potential to
occur on site. If the USFWS agrees that the habitat assessment
establishes species absence, or if subsequent protocol-level surveys
requested by the USFWS following their review of the habitat
assessment establish species absence, then no further action shall
be needed to protect this species. In the absence of USFWS
coordination, CRLF shall be presumed present within suitable aquatic
habitat on the site and protective measures described below shall be
followed.
2) A qualified biologist shall survey the work sites within 5 calendar days
prior to the onset of construction for CRLF and WPT to determine
presence (and life stage) of these species on the Project site.
Additionally, a qualified biologist shall conduct a pre-construction
survey of Project aquatic habitat for CRLF and WPT immediately
prior to the start of construction activities, beginning with installation
of exclusion fencing (see 3, below). The surveys will consist of
walking the Project work limits adjacent to areas where natural
habitat is present to ascertain presence of these species (e.g.,

site).
3) Prior to conducting preconstruction surveys, the qualified biologist
shall prepare a relocation plan that describes the appropriate survey
and handling methods for WPT and identifies nearby relocation sites
where individuals would be relocated if found during the
preconstruction surveys. The relocation plan shall be submitted to
CDFW for review prior to the start of construction activities. The
animal shall be relocated to equivalent or better WPT habitat relative
to where it was found.
4) A qualified biologist shall monitor installation of exclusion fencing
(see 4, below) to identify, capture, and relocate WPT if found, and
halt or observe work in the vicinity of CRLF if encountered onsite.
The qualified biologist shall have the authority to stop construction
activities proximate to these species and develop alternative work
practices, in consultation with construction personnel and resource
agencies (as appropriate), if construction activities are likely to affect
special‐status species or other sensitive biological resources.
Unless explicitly authorized by the USFWS (e.g., through issuance of
a Biological Opinion, CRLF shall not be relocated if encountered
within the Project site. Rather CRLF shall be allowed to disperse of
their own volition while all work is halted within 50 feet of individuals.
If a CRLF is not dispersing on its own volition, the qualified biologist
shall monitor the frog while exclusion fence installation or other work
continues, as long as they can ensure the safety of the frog. The
qualified biologist shall immediately inform the construction manager
that work should be halted or modified (in the case of a buffer or non-
dispersing individual), if necessary, to avert avoidable take of listed
species. Should egg masses, metamorphs, or tadpoles of CRLF be
identified within Project site aquatic habitat during these initial
surveys or at any time during Project construction, the USFWS shall
be contacted prior to continuation of work near the discovery.
If WPT and/or CRLF are not observed during pre-construction
surveys or installation of the exclusion fence, continued biological
monitoring during construction is not necessary. If either of these
species are observed onsite at any time, the Project Applicant shall
coordinate with USFWS and /or CDFW as necessary to determine
the appropriate measures to avoid species’ take.
5) The Project Applicant or its contractors shall install temporary
exclusion fencing around key project boundaries (i.e., at the work

areas to exclude CRLF and WPT from Project construction activities.
• Fencing shall be installed immediately prior to the start of
construction activities under the supervision of a qualified
biologist.
• The Project Applicant or their contractor shall ensure that the
temporary exclusion fencing is continuously maintained until all
Project construction activities are completed. Daily fence
inspections shall be conducted by the qualified biologist during
the first week of construction. Thereafter, the qualified biologist
may train the contractor to conduct regular inspections and
coordinate findings with the qualified biologist. Similarly, vehicles
or equipment parked overnight at the Project staging areas or
work areas shall be inspected for harboring species each
morning by the qualified biologist (or the trained contractor)
before they are moved.
• The wildlife exclusion fencing shall be a minimum height of 3
feet above ground surface, with an additional 4 to 6 inches of
fence material buried such that animals cannot burrow under the
fence.
• The exclusion fence shall not cross the marsh associated with
Pacheco Creek along the south edge of the site or bisect marsh
vegetation to allow wildlife movement to continue through these
areas when work is not occurring.
6) All onsite excavations of a depth of 8 inches or greater shall be either
backfilled at the end of each workday, covered with heavy metal
plates, or escape ramps shall be installed at a 3:1 grade to allow
wildlife that fall in a means to escape.

Mitigation Measure BIO-3a: Nesting Bird Protection Measures.
1) Project staging, project construction, vegetation removal (e.g.,
clearing and grubbing), vegetation management activities requiring
heavy equipment, or tree trimming shall be performed outside of
the bird nesting season (February 1st through August 31st) to avoid
impacts to nesting birds; if these activities must be performed
during the nesting bird season, a qualified biologist shall be
retained to conduct a pre-construction survey in the project
construction and staging areas for nesting birds and verify the
presence or absence of nesting birds no more than 5 calendar
days prior to construction activities or after any construction breaks
of 5 calendar days or more. Surveys shall be performed for the
project construction and staging areas and suitable habitat within
250 feet of the project construction and staging areas in order to
locate any active passerine (perching bird) nests and within 500
feet of the project construction and staging areas to locate any
active raptor (birds of prey) nest. If nesting birds and raptors do not
occur within 250 and 500 feet of the Project area, respectively, then
no further action is required if construction begins within 5 calendar
days.
2) If active nests are located during the pre-construction bird nesting
surveys, no- disturbance buffer zones shall be established around
nests, with a buffer size established by the qualified biologist.
Typically, these buffer distances are between 50 feet and 250 feet
for passerines and between 300 feet and 500 feet for raptors.
These distances may be adjusted depending on the level of
surrounding ambient activity and if an obstruction, such as a
building or structure, is within line-of-sight between the nest and
construction. Reduced buffers may be allowed if a full-time
qualified biologist is present to monitor the nest and has authority
to halt construction if bird behavior indicates continued activities
could lead to nest failure. Buffered zones shall be avoided during
construction-related activities until young have fledged or the nest
is otherwise abandoned.

• If areas within or adjacent to rail habitat cannot be avoided during the
breeding season (February 1 through August 31), protocol-level
surveys shall be conducted to determine rail nesting locations. The
surveys will focus on potential habitat that could be disturbed by
construction activities during the breeding season to ensure that rails
are not breeding in these locations.
Survey methods for rails will follow the Site-Specific Protocol for
Monitoring Marsh Birds, which was developed for use by USFWS and
partners to improve bay-wide monitoring accuracy by standardizing
surveys and increasing the ability to share data (Wood et al. 2017).
Surveys are conducted during the approximate period of peak
detectability, January 15 to March 25 and are structured to efficiently
sample an area in three rounds of surveys by broadcasting calls of
target species during specific periods of each survey round. Call
broadcasting increases the probability of detection compared to
passive surveys when no call broadcasting is employed. This protocol
has since been adopted by Invasive Spartina Project (ISP) and Point
Blue Conservation Science to survey Ridgway’s rails at sites
throughout San Francisco Bay Estuary. The survey protocol for
Ridgway’s rail is summarized below.
− Previously used survey locations (points) should be used
when available to maintain consistency with past survey
results. New survey points should be at least 200 meters
apart along transects in or adjacent to areas representative
of potentially suitable marsh habitat. Points should be
located to minimize disturbances to marsh vegetation. Up to
8 points can be located on a transect.
− At each transect, three surveys (rounds) are to be
conducted, with the first round of surveys initiated between
January 15 and February 6, the second round performed
February 7 to February 28, and the third round March 1 to
March 25. Surveys should be spaced at least one week
apart and the period between March 25 to April 15 can be
used to complete surveys delayed by logistical or weather
issues. A Federal Endangered Species Act Section
10(a)(1)(A) permit is required to conduct active surveys.
− Each point on a transect will be surveyed for 10 minutes
each round. A recording of calls available from USFWS is
broadcast at each point. The recording consists of 5 minutes
of silence, followed by a 30-second recording of Ridgway’s
rail vocalizations, followed by 30 seconds of silence, followed

by a 30-second recording of California black rail, followed by
3.5 minutes of silence.
• If no breeding Ridgway’s rails or black rails are detected during
surveys, or if their breeding territories can be avoided by 500 feet (150
meters), then Project activities may proceed at that location.
• If protocol surveys determine that breeding Ridgway’s rails or black
rails are present in the Project area, the following measures would
apply to project activities conducted during their breeding season
(February 1- August 31):
− A USFWS- and CDFW-approved biologist with experience
recognizing Ridgway’s rail and black rail vocalizations will be
on site during construction activities occurring within 500 feet
(150 meters) of suitable rail breeding habitat.
− If a Ridgway’s rail or black rail vocalizes or flushes within 10
meters, it is possible that a nest or young are nearby. If an
alarmed bird or nest is detected, work will be stopped, and
workers will leave the immediate area carefully and quickly.
An alternate route will be selected that avoids this area, and
the location of the sighting will be recorded to inform future
activities in the area.
− All crews working within 500 feet of aquatic habitats during
rail breeding season will be trained and supervised by a
USFWS- and CDFW-approved rail biologist.
− If any activities will be conducted during the rail breeding
season in Ridgway’s rail- or black rail-occupied marshes,
biologists will have maps or GPS locations of the most
current occurrences on the site and will proceed cautiously
and minimize time spent in areas where rails were detected.
• For vegetation management activities in suitable habitat for Ridgway’s
rail or black rail, the following measures will be implemented:
− Any herbicides to be used will be EPA-certified for use
in/adjacent to aquatic environments.
− Vegetation management activities will be limited to areas
outside of tidal marsh and non-tidal pickleweed marsh
habitats.

Mitigation Measure BIO-4a: Avoidance and Minimization Measures for Salt
Marsh Harvest Mouse.
• A USFWS and CDFW-approved biologist, with knowledge of and
experience with salt marsh harvest mouse habitat requirements, will
conduct pre-construction surveys for the species and identify and mark
suitable salt marsh harvest mouse marsh habitat prior to Project
initiation.
• Ground disturbance to suitable salt marsh harvest mouse habitat
(including, but not limited to pickleweed, and emergent salt marsh
vegetation including bulrush and cattails) will be avoided to the extent
feasible. Where salt marsh harvest mouse habitat cannot be avoided -
such as for channel excavation, access routes and grading, or
anywhere else that vegetation could be trampled or crushed by work
activities - vegetation will be removed from the ground disturbance
work area plus a 10-foot buffer around the area, as well as any access
routes within salt marsh harvest mouse habitat, utilizing mechanized
hand tools or by another method approved by the USFWS and CDFW.
Vegetation height shall be maintained at or below 5 inches above
ground. Vegetation removal in salt marsh harvest mouse habitat will be
conducted under the supervision of the USFWS- and CDFW-approved
biologist.
• To protect salt marsh harvest mouse from construction-related traffic,
access roads, haul routes, and staging areas within 200 feet of salt
marsh harvest mouse habitat will be bordered by temporary exclusion
fencing. The fence should be made of a smooth material that does not
allow salt marsh harvest mouse to climb or pass through, of a minimum
above-ground height of 30 inches, and the bottom should be buried to
a depth of at least 6 inches so that mice cannot crawl under the fence.
Any supports for the salt marsh harvest mouse exclusion fencing (e.g.,
t-posts) will be placed on the inside of the project area. The last 5 feet
of the fence shall be angled away from the road to direct wildlife away
from the road. A USFWS- and CDFW-approved biologist with previous
salt marsh harvest mouse experience will be on site during fence
installation and will check the fence alignment prior to vegetation
clearing and fence installation to ensure no salt marsh harvest mice
are present.
• All construction equipment and materials will be staged on existing
roadways and away from suitable wetland habitats when not in use.
• Vegetation shall be removed from all non-marsh areas of disturbance
(driving roads, grading and stockpiling areas) to discourage presence

of salt marsh harvest mouse.
• A USFWS- and CDFW-approved biologist with previous salt marsh
harvest mouse monitoring and/or surveying experience will be on site
during construction activities occurring in suitable habitat. The biologist
will document compliance with the project permit conditions and
avoidance and conservation measures. The USFWS-and CDFW-
approved biologist has the authority to stop project activities if any of
the requirements associated with these measures is not being fulfilled.
If salt marsh harvest mouse is observed in the work area, construction
activities will cease in the immediate vicinity of the salt marsh harvest
mouse. The individual will be allowed to leave the area before work is
resumed. If the individual does not move on its own volition, the
USFWS-approved biologist would contact USFWS (and CDFW if
appropriate) for further guidance on how to proceed.
• If the USFWS- and CDFW-approved biologist has requested work
stoppage because of take of any of the listed species, or if a dead or
injured salt marsh harvest mouse is observed, the USFWS and CDFW
will be notified within one day by email or telephone.
• For vegetation management activities in suitable habitat for salt marsh
harvest mouse, the following measures shall be implemented:
− Any herbicides to be used will be EPA certified for use
in/adjacent to aquatic environments.
− Work in upland habitat within 100 feet of salt marsh harvest
mouse habitat will be scheduled to avoid extreme high tides
when there is potential for salt marsh harvest mouse to move
to higher, drier grounds, such as ruderal and grassland
habitats.

habitat assessment of the Project site to characterize potential bat habitat and
identify potentially active roost sites. No further action is required if the pre-
construction habitat assessment does not identify bat habitat or signs of
potentially active bat roosts within the Project site (e.g., guano, urine staining,
dead bats, etc.).

that could be trimmed or removed under the Project, the following measures
shall be implemented:
1) Removal of- or disturbance to trees identified as potential bat roosting
habitat or active roosts shall occur when bats are active,
approximately between the periods of March 1 to April 15 and August
15 to October 15, to the extent feasible. These dates avoid bat
maternity roosting season (approximately April 15 to August 31) and
period of winter torpor (approximately October 15 to February 28).
a. If removal of- or disturbance to trees identified as potential
bat roosting habitat or active roosts during the periods
when bats are active is not feasible, a qualified biologist will
conduct pre-construction surveys within 5 calendar days
prior to disturbance to further evaluate bat activity within
the potential habitat or roost site.
b. If active bat roosts are not identified in potential habitat
during pre-construction surveys, no further action is
required prior to removal of- or disturbance to trees within
the pre-construction survey area.
c. If active bat roosts or evidence of roosting is identified
during pre-construction surveys, the qualified biologist shall
determine, if possible, the type of roost and species.
i) If special-status bat species or maternity or
hibernation roosts are detected during these surveys,
appropriate species- and roost-specific avoidance and
protection measures shall be developed by the
qualified biologist. Such measures may include
postponing the removal of or disturbance to trees, or
establishing exclusionary work buffers while the roost
is active. A minimum 100-foot no disturbance buffer
shall be established around special-status species,
maternity, or hibernation roosts until the qualified
biologist determines they are no longer active. The
size of the no-disturbance buffer may be adjusted by
the qualified biologist, in coordination with CDFW,
depending on the species present, roost type, existing
screening around the roost site (such as dense
vegetation), as well as the type of construction activity
that would occur around the roost site, and if
construction would not alter the behavior of the adult
or young in a way that would cause injury or death to
those individuals.
Active maternity roosts shall not be disturbed without

advance CDFW approval until the roost disbands at
the completion of the maternity roosting season or
otherwise becomes inactive, as determined by the
qualified biologist.
ii) If a common species, non-maternity or hibernation
roost (e.g., bachelor daytime roost) is identified,
disturbance to- or removal of trees or structures may
occur under the supervision of a qualified biologist as
described under 3).
2) The qualified biologist shall be present during tree disturbance or
removal if active non-maternity or hibernation bat roosts or potential
roosting habitat are present. Trees with active non-maternity or
hibernation roosts of common species or potential habitat shall be
disturbed or removed only under clear weather conditions when
precipitation is not forecast for three days and when daytime
temperatures are at least 50°F to ensure bats are active and can
abandon any potential roosts as disturbance from the clearing
activities occurs, and when wind speeds are less than 15 mph.
Trimming or removal of trees with active (non-maternity or
hibernation) or potentially active roost sites of common bat species
shall follow a two-step removal process:
a. On the first day of tree removal and under supervision of
the qualified biologist, branches and limbs not containing
cavities or fissures in which bats could roost, shall be cut
only using hand tools (e.g., chainsaws).
b. On the following day and under the supervision of the
qualified biologist, the remainder of the tree may be
removed, either using hand tools or other equipment (e.g.
excavator or backhoe).
c. All felled trees shall remain on the ground for at least 24
hours prior to chipping, off-site removal, or other
processing to allow any bats to escape, or be inspected
once felled by the qualified biologist to ensure no bats
remain within the tree and/or branches.
3) Bat roosts that begin during construction are presumed to be
unaffected as long as a similar type of construction activity continues,
and no buffer would be necessary. Direct impacts on bat roosts or
take of individual bats will be avoided.

Wildrye Grassland. The following measures shall be implemented prior to
construction to avoid or minimize impacts to creeping wildrye grassland within
the Project site.
1) A qualified botanist shall identify the boundaries of creeping wildrye
grassland within the Project site during the flowering season
(between June and July) and prior to site grading. Boundaries of this
sensitive natural community shall be mapped and flagged for
avoidance, if feasible.
2) Where avoidance of this community is infeasible, the perennial
grasses shall be harvested at the appropriate time and under the
direction of the qualified botanist from locations where grading and/or
ground disturbance will occur within the Project site.
3) Harvested grasses shall be stored for reintroduction into suitable
habitat within upland portions of the Project site that will be preserved
as open space.
4) The Project applicant shall contract a qualified restoration ecologist to
prepare a Monitoring Plan for relocated / transplanted creeping
wildrye grasses within the Project site. The plan shall detail methods
and location for relocating or reintroducing the grasses, success
criteria, monitoring methods and maintenance for successful
establishment, reporting protocols, and contingency measures to be
implemented if the initial mitigation fails. The plan shall be developed
in coordination with the appropriate agencies prior to the start of local
construction activities, with the objective of providing equal or better
habitat and populations than the impacted area(s). The
recommended success criteria for relocated plants shall be 1:1 ratio
[number of plants established: number of plants impacted] after two
years, unless otherwise specified by CDFW.
5) The plan shall be submitted to the County and CDFW prior to the
start of local construction activities within the boundaries of the

that will be preserved as open space following development.
The Project sponsor shall contract with a qualified restoration ecologist
to prepare a Habitat Mitigation and Monitoring Plan (HMMP) for oak
woodland habitat to be restored as part of the Project. The HMMP
would be subject to approval by Contra Costa County. The HMMP shall
include a detailed description of restoration/enhancement/preservation
actions proposed such as a planting plan, a weed control plan to
prevent the spread of invasive and non-native species within restored
areas, and erosion control measures to be installed around the restored
area following mitigation planting to avoid or minimize sediment runoff
throughout the Project site; restoration performance criteria for the
restored area that establish success thresholds over a period of 5
years; and proposed monitoring/maintenance program to evaluate the
restoration performance criteria, under which progress of restored
areas are tracked to ensure survival of the mitigation plantings. The
program shall document overall health and vigor of mitigation plantings
throughout the monitoring period and provide recommendations for
adaptive management as needed to ensure the site is successful,
according to the established performance criteria. An annual report
documenting the results and providing recommendations for
improvements throughout the year shall be provided to the County.
In designing the Tree Replacement Plan, the arborist shall review the
final project grading plans to ensure that adequate tree preservation
methods, guidelines, and conditions are in place. The project arborist
shall host pre-demolition meetings with the general contractor and
demolition contractor to determine clearance pruning, stump removal
techniques, fencing placement and, timing to establish a Tree
Protection Zone (TPZ). The arborist shall conduct post-demolition
meetings to review and confirm tree protection fencing for grading
and construction. All vehicles, equipment, and storage of job site
materials and debris, shall be kept outside of the TPZ. The arborist
shall incorporate standard protocols set forth in the American

Mitigation Measure BIO-6a: Protection of Jurisdictional Wetlands and
Other Waters. For Project development within or adjacent to state and federal
jurisdictional wetlands and waters, protection measures shall be applied to
protect these features. These measures shall include the following:
1) An updated wetland delineation shall be submitted to USACE for
verification to establish the boundaries and current jurisdictional status
of the aquatic features in the site. The verified wetland delineation shall
be used to quantify the Project impacts to aquatic resources for
permitting purposes.
2) To the maximum extent feasible, Project construction activities within
or adjacent to wetlands or waters shall be conducted during the dry
season (between June 15 and October 15) and the disturbance
footprint shall be minimized in these areas.
3) Stabilize disturbed, exposed slopes immediately upon completion of
construction activities (e.g., following cut and fill activities and
installation of bioretention pond infrastructure) to prevent any soil or
other materials from entering aquatic habitat. Plastic monofilament of
any kind (including those labeled as biodegradable, photodegradable,
or UV-degradable) shall not be used. Only natural burlap, coir,
coconut or jute wrapped fiber rolls and mats shall be used.
4) A protective barrier (fence) shall be erected around any wetlands or
waters designated for complete avoidance in Project construction
plans and regulatory permits to isolate it from construction or other
ground-disturbing activities.
5) A fencing material meeting the requirements of both water quality
protection and wildlife exclusion may be used. Fences must be
properly installed with final approval by a County representative,
including adequate supports or wire backing for use if windy
conditions are anticipated, and with the lower edge keyed in to the
soil to ensure a proper barrier. Signage shall be installed on the
fencing to identify sensitive habitat areas and restrict construction
activities;
6) No equipment mobilization, grading, clearing, or storage of vehicles,
equipment or machinery, or similar activity shall occur until a County
representative has inspected and approved the wetland protection

7) The Project proponent shall ensure that the temporary fence is
continuously maintained until all construction or other ground-
disturbing activities are completed; and
8) Drip pans and/or liners shall be stationed beneath all equipment
staged nearby jurisdictional features overnight to minimize spill of
deleterious materials into jurisdictional waters. Equipment
maintenance and refueling in support of project implementation shall
be performed in designated upland staging areas and work areas,
and spill kits shall be available on-site. Maintenance activity and
fueling must occur at least 100 feet from jurisdictional wetlands and
other waters or farther as specified in the Project permits and
authorizations.
Mitigation Measure BIO-6b: Permits and Compensation for Impacts to
Wetlands and Waters.
To offset unavoidable permanent impacts to approximately 0.02 acres of the
side-hill seep and the fill of less than 0.1 acres for construction of the storm
drain outfall along the bank of Pacheco Creek, the Project applicant shall
secure the appropriate permits and provide compensatory mitigation as
determined by the regulatory agencies with jurisdiction over the impacted
aquatic resources during the permitting process. To establish the jurisdictional
status of the various aquatic features in the site, the updated wetland delineation
will be submitted to USACE for verification. The necessary permits will depend on
the jurisdictional status of the features. While the outfall in Pacheco Creek is
expected to require permits from USACE (Nationwide 7), CDFW (1602
Streambed Alteration Agreement), and RWQCB (401 Certification), the
permitting scenario of the side-hill seep is less predictable. It is possible
USACE will verify this feature as outside Clean Water Act jurisdiction due to
spatial and hydrological isolation from other Waters of the U.S. If the seep is
verified as non-jurisdictional, the Regional Water Quality Control Board Water
would be expected to issue a Notice of Applicability to authorize its fill pursuant
to Water Quality Order No. 2004-0004-DWQ.
At a minimum, or as determined by the USACE, compensation acreage for
impacted wetlands and waters would meet a 1:1 ratio
(created/restored/enhanced: impacted) to achieve no net loss of aquatic
resources. Compensation may be accomplished through the purchase of
credits at an agency-approved mitigation bank or in-lieu fee program.
Alternatively, compensation may be accomplished through on-site or off-site
creation, restoration, or enhancement of jurisdictional resources, subject to the
approval of the permitting agencies. On-site or off-site
creation/restoration/enhancement plans must be prepared by a qualified
biologist prior to construction, include a planting plan and planting methods,

4.4 Cultural Resources and Tribal Cultural Resources
Mitigation Measure CUL-1a: If prehistoric or historic-period archaeological
resources are encountered during Project implementation, including ground
disturbance associated with project construction, all construction activities
within 100 feet shall halt, and a qualified archaeologist, defined as an
archaeologist meeting the U.S. Secretary of the Interior’s Professional
Qualification Standards for Archeology, shall inspect the find within 24 hours of
discovery and notify the County of their initial assessment. Prehistoric
archaeological materials might include obsidian and chert flaked-stone tools
(e.g., projectile points, knives, scrapers) or toolmaking debris; culturally
darkened soil (“midden”) containing heat-affected rocks, artifacts, or shellfish
remains; and stone milling equipment (e.g., mortars, pestles, handstones, or
milling slabs); and battered stone tools, such as hammerstones and pitted
stones. Historic-period materials might include building or structure footings and
walls, and deposits of metal, glass, and/or ceramic refuse.
If the County determines, based on recommendations from a qualified
archaeologist and a Native American representative (if the resource is Native
American-related), that the resource may qualify as a historical resource or
unique archaeological resource (as defined in CEQA Guidelines Section
15064.5) or a tribal cultural resource (as defined in PRC Section 21080.3), the
resource shall be avoided if feasible. If avoidance is not feasible, the County
shall consult with appropriate Native American tribes (if the resource is Native
American-related), and other appropriate interested parties to determine
treatment measures to avoid, minimize, or mitigate any potential impacts to the
resource pursuant to PRC Section 21083.2, and CEQA Guidelines
Section 15126.4. This shall include documentation of the resource and may
include data recovery (according to PRC Section 21083.2), if deemed
appropriate, or other actions such as treating the resource with culturally
appropriate dignity and protecting the cultural character and integrity of the
resource, determined by a qualified professional or California Native American
tribe, as is appropriate (according to PRC Section 21084.3), All significant
cultural materials recovered shall, at the discretion of the consulting
professional, be subject to scientific analysis, professional museum curation,
and documentation according to current professional standards.

In considering any suggested mitigation proposed by the consulting
professional to mitigate impacts to cultural resources, the County shall
determine whether avoidance is feasible in light of factors such as the nature of
the find, project design, costs, and other considerations.
If avoidance is infeasible, other appropriate measures, such as data recovery,
shall be instituted. The resource shall be treated with the appropriate dignity,
taking into account the resource’s historical or cultural value, meaning, and
traditional use, as determined by a qualified professional or California Native
American tribe, as is appropriate. Work may proceed on other parts of the
project site while mitigation for cultural resources is carried out. All significant
cultural materials recovered shall, at the discretion of the consulting
professional, be subject to scientific analysis, professional museum curation,
and documentation according to current professional standards. At the County’s
discretion, all work performed by the consulting professional shall be paid for by

III. BACKGROUND
In 2004, the applicant (Discovery Builders) submitted applications for the Bayview
Estates Residential Project. Initially, the applicant proposed a 163-lot subdivision
development. The County analyzed the 163-lot proposal in a 2008 Draft EIR. In
response to comments received on the Draft EIR, in November 2010, the applicant
submitted a “Lesser Intensity Project Alternative” to the project analyzed in the
2008 Draft EIR. The Lesser Intensity Project Alternative consisted of the current
144-lot revised layout and a revised grading plan that retained the existing top
elevation of Vine Hill. This 144-lot alternative project proposal was also designed
to alleviate potential water pressure issues identified in the original project by
lowering the elevation of residential development on the project site. The project
applicant continued to coordinate with the County to further refine the project’s
stormwater plan, grading in certain development areas and wetlands on the
project site, as well as utility infrastructure alignments; and accordingly in 2017, the
County reinitiated the CEQA process based on the currently proposed 144-lot
subdivision and issued a new Notice of Preparation. The currently proposed
project analyzed in the new Draft EIR incorporates the aforementioned refinements
to the original proposal. The new Draft EIR presents an independent, stand-alone
analysis of the project; it is not a recirculation of the 2008 Draft EIR, nor is the

recent EIR analysis a comparative assessment of the current project and the
original proposal.
IV. GENERAL INFORMATION
1. General Plan: Heavy Industry (HI)
2. Zoning: Heavy Industrial District (H-I)
3. California Environmental Quality Act: An Environmental Impact Report (EIR) was
prepared and published for the project (State Clearinghouse# 2008032074). The
45-day public review period for the Draft EIR started on May 13, 2021 and was
scheduled to close on June 28, 2021, but was extended an additional 14 days
until July 12, 2021. The County received 21 comment letters during the
comment period on the Draft EIR for the proposed project. A Final EIR has
been prepared that includes the comments received on the Draft EIR and the
County’s responses to those comments. The Final EIR also includes associated
text changes relating to the comment responses. A Mitigation Monitoring
Reporting Program has also been prepared. (See also Section VIII. of this
report.)
4. Tribal Cultural Resources: In 2017, pursuant to the requirements of Public
Resources Code (PRC) Section 21084.3, the County solicited tribal consultation.
The County sent letters to the Native American tribes provided by the Native
American Heritage Commission as having an interest in the proposed project
vicinity. The letter included a project description and a map of the project site.
The County also sent previous cultural analyses to the Wilton Rancheria, who
requested by letter (dated June 16, 2017) information regarding cultural
resources studies completed for the project. At that point, no response was
received requesting further consultation.
5. Previous Applications:
174-64. Application for a land use permit to establish a cement products
manufacturing plant and contractors yard. The application was denied by the
Board of Supervisors on September 17, 1964.

V. SITE/AREA DESCRIPTION
The project site is located along the northern I-680 corridor in Contra Costa
County. It is within the Vine Hill/Pacheco Boulevard Area, of the County’s
unincorporated communities, as shown in the General Plan. The Vine Hill/Pacheco
Boulevard Area is located in North Central Contra Costa County, east of the City of
Martinez and northwest of the City of Concord. The project site is a single 78.2-acre
parcel and is bounded by the Contra Costa Canal and Burlington Northern Santa Fe
Railroad (BNSF) Railway tracks to the southwest and south, residential
development to the northwest, Pacheco Creek to the east, and Central Avenue to
the northeast. The project site is currently undeveloped and consists of relatively
flat wetland and marsh areas in the east, rising sharply to the summit of the
prominent hill (Vine Hill) in the western part of the site. Elevations on the site range
from 4 to 283 feet above mean sea level (msl). The property supports permanent
and seasonal wetlands and an extensive band of freshwater marsh in the eastern
and southern part of the site. A Valley Oak woodland grove of 34 native oak trees
covers a small area mid-slope on the north-facing side of the hill.
The immediate surrounding area is developed with roads, trails and residential
communities, as well as industrial uses including gas pipelines, a landfill and
wastewater treatment facilities, and also includes areas of open space. The vicinity
of the project site is characterized by a variety of land uses. I-680 extends in a
northwest-southeast direction west and south of the project site.
To the West: The area directly west of the freeway supports a mix of residential,
commercial, and light industrial uses, including a self-storage facility. Further west
the uses are primarily residential development, including the County’s
unincorporated Mountain View neighborhood and suburban areas of the City of
Martinez.
To the Northwest: Parcels to the northwest of the site and east of the freeway are
characterized by single-family homes within the General Plan land use designation
Single Family High Density (SH). Further northwest is the Waterbird Regional
Preserve, which is an approximately 198-acre wetland and associated upland area
managed jointly by the East Bay Regional Park District (EBRPD), the Mountain View
Sanitary District (MVSD), the Contra Costa County Mosquito and Vector Control
District and the California Department of Fish and Wildlife (CDFW).

Page 6 of 24
To the Northeast, East and South: Lands to the northeast, east and south are
mostly undeveloped properties zoned for heavy industrial purposes. Undeveloped
lands and recreational vehicle storage occupy areas immediately south of the
railroad tracks. The Maltby sanitary sewer pumping station, operated by the Central
Contra Costa Sanitary District (CCCSD), is directly adjacent to the project site to the
east. The Conco construction and trucking yard is also located east of the site and
Pacheco Creek. The majority of the land to the north and northeast of the project
site is property of the Acme Landfill. While the landfill is currently mostly inactive, a
fully operational refuse transfer station is located approximately 0.3 miles north of
the project site. In addition, heavily industrialized land areas supporting Shell
Martinez Refinery and the Marathon Refinery (previously Tesoro Golden Eagle and
Tosco) are located approximately one mile northwest and east respectively.
Underground pipelines carrying crude oil and refined petroleum products
(gasoline, diesel fuel, and jet fuel) run under Central Avenue and the project site
along a wetland area on the northeastern boundary of the site.
VI. PROJECT DESCRIPTION
The project sponsor proposes to develop a phased 144-unit residential subdivision
on approximately 78.2-acres of vacant land in the Vine Hill/Pacheco Boulevard area
of unincorporated Contra Costa County. The proposed project includes the
following major components on and adjacent to the project site:
1. A Vesting Tentative Map (VTM) for development of up to 144 detached
single-family homes and associated new internal roadways on
approximately 31.8 acres of the project site;
2. Approximately 42 acres of open space, marshes and undeveloped land,
including:
• The preservation of approximately 20.1 acres of the upper hill area
shown as “Parcel A” on the VTM;
• The preservation of approximately 19.8 acres of the lower site areas
(containing wetlands, coastal salt marsh, freshwater marsh, open water,
and alkali meadow) shown as “Parcel B” on the VTM;
• The development of a new 2.0-acre stormwater treatment basin, in
accordance with the County’s C.3 Guidebook, and shown as “Parcel F” on
the VTM;

Page 7 of 24
3. Development of an approximately 4.5-acre private neighborhood park in
proximity to “Parcel B” and “Parcel F”;
4. A grading permit for onsite grading of approximately 900,000 cubic yards of
earth material for residential subdivision development, including substantial
grading of the lower hill area and limited grading of the upper hill area in
order to balance overall project cut and fill earthwork volumes;
5. Extension of new utility lines to and throughout the project site, and the
repair and upgrade of existing off-site utility lines;
6. Improvement of two existing off-site roadways, Central Avenue and Palms
Drive, to better accommodate two lanes of moving vehicular traffic to/from
the project site;
7. A tree permit to remove up to 30 code-protected trees; and
8. The project also includes requests for exceptions to Title 9 relating to
roadway and detention basin standards.
To support the proposed land use and density, the project proposes to amend the
existing Contra Costa County General Plan land use map to change the existing
Heavy Industrial (HI) land use designation to the Single Family Residential High
Density (SH)(5.0-7.2 units/acre) and Open Space (OS) land use designations. Also,
the project proposes to rezone the existing Heavy Industrial (H-I) zoning
designation on the project site to the Planned Unit District (P-1) designation. The
applicant is also requesting exceptions to Division 98 (Streets) and Division 914
(Drainage) of Title 9 of the County Ordnance Code. The project includes the
following applications:
1) CDGP04-00013. Proposal for a General Plan Amendment to change the
General Plan land use designation from Heavy Industry (HI) to Single Family
Residential-High Density (SH)(5.0-7.2 units/acre) and Open Space (OS) land
use designations.
2) CDRZ04-03148. Proposal to rezone a vacant 78.2-acre property currently
zoned Heavy Industrial District (H-I) to Planed Unit District (P-1) for
predominantly single-family-residential use. The rezoning would allow

development of single-family homes on the site, which currently allows only
heavy industrial uses under the existing zoning designation.
3) CDSD04-08809. A phased Major Subdivision application, including a
Vesting Tentative Map, to subdivide the property into 144 lots and four (4)
open space parcels including a private park, one hillside open space parcel,
one storm drainage parcel, and a roadway parcel. The subdivisions streets
will be private but would be constructed to public road standards. This
application also includes requests for exceptions to Sections 98-4.002, 92-
4.012, and 914-12.010 of Title 9 relating to roadway and detention basin
standards.
4) CDDP04-03080. A proposal for a Preliminary and Final Development Plan
for the development of 144 single-family residences to be accessed by way
of southern portions of Palms Drive and Central Avenue. The project
proposes open space parcels, one of which is proposed as a private
neighborhood park. This application also includes requests for a Tree
Permit to remove up to 30 code-protected trees, and a Grading Permit for
proposed onsite grading of approximately 900,000 cubic yards of earth
material for residential subdivision development, including grading of the
lower hill area and limited grading of the upper hill area in order to balance
overall project cut and fill earthwork volumes.
VII. AGENCY COMMENTS
The project applications were filed in 2004. Comments were initially received at
that time from the Public Works Department, the Fire District, the Transportation
Planning Section, the Flood Control District, the California Historical Resources
Information System, the Mt. View Sanitary District, the Central Contra Costa
Sanitary District, the Contra Costa Water District, and the California Department of
Fish & Wildlife. Due to the age of the initial agency comments on the original
project applications, they are considered outdated. Therefore, only key comments
relating to aspects of the project that have been ongoing priorities for particular
agencies throughout the process are cited here.
1. Public Works Department (PWD): The PWD has provided several project
comment letters since 2004 relating to project access, required public road
standards, traffic and circulation, drainage, and stormwater control and
CPC – February 23, 2022
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080

water quality. The final PWD staff report and conditions of approval for the
project was submitted on November 17, 2021.
2. Mt. View Sanitary District (MVSD): The MVSD has provided several project
comments since 2004. The comments have generally related to information
requests to confirm the capacity of the project’s proposed sewer system,
plan submittal for engineering and design review by MVSD of the proposed
sanitary system, hydraulic analysis relating to sewer pumps sanitary pump
stations that will service the project, and upgrade requirements to existing
abandoned upstream sewer pipes and manholes that will be put back into
service in order to implement the project. MVSD issued a “Will Serve” letter
confirming its plan to provide wastewater utility service to the project site.
MVSD is in the process of preparing an updated capacity study that will
include the Bayview project site; the study is expected to be available
sometime in 2022. Final project improvement plans will have to be prepared
in accordance with current MVSD standards and will be evaluated against
the updated capacity study and models.
3. Contra Costa Water District (CCWD): The CCWD has also provided several
project comments since 2004. These comments have pertained to potential
project impacts on CCWD property and Contra Costa Canal right-of-way,
CCWD regulations and requirements relating to project water service,
proposed locations of water lines, and the design elevations of development
potentially affecting water pressure.
VIII. ENVIRONMENTAL REVIEW
The County prepared an Environmental Impact Report (EIR) for the project (State
Clearinghouse# 2008032074). The project EIR is composed of both a Draft EIR and
Final EIR. The Notice of Preparation (NOP) of the EIR was posted on June 7, 2017
and a public Scoping Meeting was held on July 17, 2017. Both written and oral
comments were received during the NOP public comment period and the Scoping
Meeting; the comments were responded to in the Draft EIR, which was released for
public review on May 13, 2021 with a Notice of Availability. A 45-day comment
period for the Draft EIR began on May 13, 2021 through June 28, 2021 and was
extended at the request of the public for an additional 2 weeks until July 12, 2021.
During the comment period, the County received 21 comment letters on the Draft
EIR for the proposed project. The comment topics included concerns about traffic
CPC – February 23, 2022
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 10 of 24
congestion, views, tree removal, impacts to wildlife, adequacy of emergency
services, sanitary and water service, and petroleum pipelines. The County’s
Reponses to the comments received are provided in the Final EIR that has been
prepared for certification by the County Planning Commission.
The EIR for the proposed project identified two significant and unavoidable effects
related to vehicle miles traveled (VMT) for the project, including:
1) Total Home Based VMT per resident generated by the project would be
greater than 15 percent below the regional VMT for similar uses in Contra
Costa County, resulting in a significant impact for the project.
2) Total Home Based VMT per resident generated by the project would be
greater than 15 percent below the regional VMT for similar uses in Contra
Costa County, resulting in a significant impact for the project.
When a public agency determines that a project will have significant and
unavoidable effects, Public Resources Code section 21081(b) requires that the
public agency make findings of overriding considerations to demonstrate that
economic, legal, social, technological, or other benefits of the project outweigh the
significant environmental effects of the project. Accordingly, the County has made
the requisite findings of overriding consideration and has found that the potential
benefits of the project do in fact outweigh the environmental impacts. The
project’s benefits include, Jobs-housing balance, provision of parks and open
spaces, new housing inventory, street improvements for Palms Drive and Central
Avenue, and upgraded water and sanitary services, and public nuisance abatement
of illegal uses of the project site. The County’s findings of overriding
consideration are attached to this staff report in the project’s findings and
proposed conditions of approval (Exhibit #1).
In addition, other potentially significant impacts were also identified, all of which
can be mitigated to a less-than-significant level. These impacts affect the
environmental topics of:
• aesthetics,
• air quality,
• biological resources,
• cultural & tribal cultural resources,
• geology & soils,
CPC – February 23, 2022
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 11 of 24
• GHG emissions,
• hazards & hazardous materials,
• hydrology/water quality,
• noise,
• public services,
• transportation,
• and utilities/service systems.
Environmental analysis contained in the EIR determined that measures were
available to mitigate these potential adverse impacts to less-than-significant levels.
As discussed previously, a Final EIR has been prepared that includes the written
comments received on the Draft EIR and the County’s responses to the comments
received. The Final EIR also includes County-initiated updates and errata to the
Draft EIR. These errata constitute minor text changes to the Draft EIR and occurred
in Section 4.3: Biological Resources, Section 4.6: Greenhouse Gas Emissions and
Energy, Section 4.12: Public Services and Recreation, Section 4.13: Transportation
and Circulation, and Section 4.14: Utilities and Service Systems (see chapter 4 in the
Final EIR). The changes were made primarily to correct grammatical and
typographical errors, as well as to improve accuracy and readability of certain
passages. The text changes are not the result of any new significant adverse
environmental impact, and do not alter the effectiveness of any mitigation included
in the pertinent section, and do not alter any findings in the Draft EIR. Pursuant to
CEQA Guidelines Section 15088.5(a), recirculation of a Draft EIR is required only if:
“1) a new significant environmental impact would result from the project or
from a new mitigation measure proposed to be implemented;
2) a substantial increase in the severity of an environmental impact would
result unless mitigation measures are adopted that reduce the impact to a
level of insignificance;
3) a feasible project alternative or mitigation measure considerably different
from others previously analyzed would clearly lessen the environmental
impacts of the project, but the project’s proponents decline to adopt it; or
4) the draft EIR was so fundamentally and basically inadequate and
conclusory in nature that meaningful public review and comment were
precluded.”
None of the text edits or changes to the Draft EIR meet any of the above conditions;
CPC – February 23, 2022
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 12 of 24
therefore, recirculation of any part of the Draft EIR is not required. The information
presented in the project EIR supports this determination by the County.
Pursuant to CEQA Guidelines Section 15097, a Mitigation Monitoring Program has
been prepared, based on the identified significant impacts and mitigation
measures in the project EIR. The Mitigation Monitoring Program is intended to
ensure that the mitigation measures identified in the EIR are implemented. The
Mitigation Monitoring Program is attached to this staff report (Exhibit #6). All
mitigation measures are included in the Conditions of Approval and Advisory
Notes.
IX. STAFF ANALYSIS
1. General Plan Consistency: The proposed Bayview Estates Residential Project is
consistent with the General Plan. The project sponsor proposes to develop a
144-lot residential subdivision on approximately 78.3-acres of vacant land. To
support the proposed land use and density, the project proposes to amend the
existing Contra Costa County General Plan land use map to change the existing
Heavy Industry (HI) land use designation to the Single-Family Residential-High
Density (SH)(5.0-7.2 units/net acre) and Open Space (OS) land use designations.
The proposed change of the land use designation of the project site from HI to
SH is compatible with the contiguous existing residential neighborhood to the
north along Palms Drive and Central Avenue, which the General Plan also
designates as SH.
The SH designation allows between 5.0 and 7.2 units per net acre. 144 detached
single-family homes and associated new internal roadways and a neighborhood
park will be developed on approximately 36.3 acres, and the remaining acreage
will comprise open space, wetlands, and undeveloped land. Subdivision
CDSD04-08809, as proposed, includes 144 units on 27.2 net developable acres
of the project site. The density range of the SH land use designation in the
General Plan is 5.0 to 7.2 units per net acre, which allows the project site a
minimum of 136 units and a maximum of 196 units, which translates to 5.3 units
per net acre, and is therefore within the allowable SH density range. Thus, the
proposed project with 144 single-family units is consistent with the SH General
Plan designation.
A. General Plan Policies: The application is subject to the General Plan’s
CPC – February 23, 2022
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 13 of 24
“Policies for the Vine Hill/Pacheco Area” (policies 3-105 through 3-107).
These policies are highlighted below:
• 3-105. The scenic assets and unstable slopes of the Vine Hill Ridge are to
be protected for open space/agricultural use.
• 3-106. The residential neighborhood east of I-680 shall be buffered from
the industrial/landfill-related uses.
• 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.
B. Housing Element: The project is also consistent with the following General
Plan Housing Element goals and policies.
Goal 1. Maintain and improve the quality of the existing housing stock and
residential neighborhoods in Contra Costa County.
Goal 6. Provide adequate sites through appropriate land use and zoning
designations to accommodate the County’s share of regional housing
needs.
Goal 9. Promote energy efficient retrofits of existing dwellings and
exceeding building code requirements in new construction.
The project site is listed in the housing site inventory that is maintained by
the Housing and Community Improvement Division, as a site suitable for
residential development. The project would allow for additional housing
opportunities on a vacant underutilized property that may be developed to
meet the housing demands and needs of the County and region. The
development of 144 market-rate units on the property is expected to
contribute towards meeting the County’s future 6th Cycle Housing Element
Regional Housing Needs Allocation (RHNA). The 6th Cycle Housing Element
covers the planning period from 2023 to 2031 and includes a RHNA of 7,610
housing units as determined by ABAG/MTC as the unincorporated County’s
fair share of development towards the regional housing need. The subject

CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 14 of 24
property is listed in the current 5th Cycle Housing Element sites inventory as
available land for the potential development of housing. The total number
of market rate units that the County is responsible for development is 3,133,
and this project would provide a significant contribution towards meeting
that goal.
C. Noise Element: The General Plan Noise Element includes the following goals
and policies that are applicable to the proposed project:
Goal 11-A. To improve the overall environment in the County by reducing
annoying and physically harmful effects of noise for existing and future
residents and for all land uses.
Goal 11-C. To ensure that new developments will be constructed so as to
limit the effects of exterior noise on the residents.
Policy 11-1. New projects shall be required to meet acceptable exterior
noise level standards as established in the Noise and Land Use Compatibility
Guidelines contained in Figure 11-6. These guidelines, along with the future
noise levels shown in the future noise contour maps, should be used by the
County as a guide for evaluating the compatibility of “noise sensitive”
projects in potentially noisy areas.
Policy 11-8. Construction activities shall be concentrated during the hours of
the day that are not noise-sensitive for adjacent land uses and should be
commissioned to occur during normal work hours of the day to provide
relative quiet during the more sensitive evening and early morning hours.
The Community Noise Exposure Levels on Figure 11-6 of the General Plan
Noise Element show that levels of 60 dB or less are normally acceptable and
70 dB or less are conditionally acceptable for single-family residential land
uses. Due to the proximity of Interstate 680 immediately to the east of the
project site and the Burlington Northern Santa Fe rail corridor on the
southern boundary, future noise levels on the project site would exceed the
60 dB normally acceptable level for single-family residents and could result
in noise impacts on project residents. Modern construction materials and
design techniques generally mitigate such “environment-on-project”
impacts to non-significant levels; therefore, the new residences should not

experience excessive noise issues.
With respect to project construction, the project EIR included mitigation
measures for avoiding excessive groundborne vibration and construction
noise, by requiring the applicant to create and implement a development-
specific noise-reduction plan to reduce noise at sensitive receptors along
Central Avenue to below 75 dBA Lmax. Contractors may elect any
combination of legal, non-polluting methods to maintain or reduce
construction-related noise to threshold levels or lower, as long as those
methods do not result in other significant environmental impacts or create a
substantial public nuisance. Examples of measures that can effectively
reduce noise impacts include locating equipment in shielded and/or less
noise-sensitive areas, selection of equipment that emits low noise levels,
and/or installation of noise barriers such as enclosures to block the line of
sight between the noise source and the nearest receptors. Other feasible
controls could include, but shall not be limited to, fan silencers, enclosures,
and mechanical equipment screen walls.
In addition, the project has been conditioned to limit construction activities
to daytime hours between 8:00 am and 5:00 pm Monday through Friday.
The aforementioned development-specific noise-reduction plan for
attenuating construction-related noises shall be implemented prior to the
initiation of any work that triggers the need for such a plan. These
mitigation measures are included in the conditions of approval #s 78, 96, 97,
and 98. As conditioned, the proposed project would be consistent with the
applicable goals and policies of the Noise Element.
D. Transportation and Circulation Element: The Transportation and Circulation
Element of the General Plan shows designated arterials and expressways
that are part of the County roadway network. Arthur Road is a southwest-
northeast oriented collector and extends from Pacheco Boulevard to a
residential area north of the project site. West of the project site, the
roadway has one travel lane in each direction. The I-680/Arthur Road
interchanges provides access to/from points north along I-680.
Central Avenue is a local road with one travel lane in each direction north of
the project site. This roadway is maintained by the County between Arthur
Road and Darcie Way and becomes an unpaved private road as it extends to
CPC – February 23, 2022
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 16 of 24
the project site and CCCSD Maltby pump station. This road would be
widened and paved as part of the project, serving as the main access
roadway to the project site. The posted speed limit between Arthur Road
and Darcie Way is 25 miles-per hour and has a suggested speed limit of 5
miles-per-hour on the privately owned segment. Central Avenue currently is
not a through street and would serve as a main access roadway to the
project site. Palms Drive is a local road with one travel lane in each direction
north of the project site. The surface pavement conditions are poor with
uneven and missing pavement. The road is not a through street and would
be extended to the project site as a secondary access. The speed limit is not
posted.
Analysis in the project EIR indicates that the project’s projected trip
generation of 1,360 additional daily trips with 107 AM peak hour vehicle
trips and 143 PM peak hour trips would increase traffic volumes on
residential roadway segments near the project site resulting in obstacles (or
hazards) for project vehicle traffic. Therefore, in accordance with County
requirements and design standards, the project has been conditioned to
mitigate these impacts by providing even surface pavement, appropriate
signage, delineation, and other features on Palms Drive (and Central Avenue
if it becomes a public street) to improve vehicle transportation conditions
and eliminate obstacles (or hazards). The project EIR did not find that the
project’s traffic volumes would have any substantial congestive effect on the
area arterials.
The project EIR did identify that the project would have significant impacts
on VMT (“Vehicle Miles Traveled”) for the project. CEQA Guidelines
§15064.3(a) states that VMT “refers to the amount and distance of
automobile travel attributable to a project.” These impacts were analyzed in
the EIR based on the project’s effect on VMT and its effects on the
pedestrian, bicycle, and transit modes of travel, and it was found that the
total Home-Based VMT per resident generated by the project would be
greater than 15 percent below the regional VMT for similar uses in Contra
Costa County, and that the cumulative Countywide VMT would also increase
as a result of the project. These VMT impacts were identified as significant
and unavoidable in the EIR. Notwithstanding the significant and unavoidable
level of the project’s impacts on VMT, the project has nonetheless been
conditioned to mitigate these impacts the maximum extent feasible by
CPC – February 23, 2022

requiring prior to issuance of building permits for the project applicant to
develop a transportation and parking demand management plan (TDM).
The applicant shall submit the TDM program to the County Department of
Conservation and Development for review and approval. The TDM program
shall identify trip reduction strategies as well as mechanisms for funding and
overseeing the delivery of trip reduction programs and strategies. The TDM
program shall be designed to achieve the trip reduction, as required to
reduce the VMT per resident from 20.6 to 16.5, to the extent feasible,
consistent with a 20 percent reduction in the near-term. Thus, the project
would be consistent with General Plan transportation policies.
E. Open Space Element: The Open Space Element of the General Plan contains
goals and policies pertinent to the preservation and management of open
spaces within the County. Approximately 44.5 acres of the 78.3-acre project
site will be designated open space, natural wetlands, and park areas.
Therefore, the project is consistent with the following goals and policies of
the Open Space Element.
Goal 9-A. To preserve and protect the ecological, scenic, cultural/historic,
and recreational resource lands of the county.
Goal 9-B. To conserve the open space and natural resources of the county
through control of the direction, extent, and timing of urban growth.
Goal 9-C. To achieve a balance of open space and urban areas to meet the
social, environmental, and economic needs of the county now and for the
future.
Policy 9-1. Permanent open space shall be provided within the county for a
variety of open space uses.
Policy 9-2. Historic and scenic features, watersheds, natural waterways, and
areas important for the maintenance of natural vegetation and wildlife
populations shall be preserved and enhanced.
Policy 9-13. Providing public facilities for outdoor recreation should remain
an important land use objective in the county, as a method of promoting
high scenic quality, for air quality maintenance, and to enhance outdoor
CPC – February 23, 2022
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 18 of 24
recreation opportunities of all residents.
Policy 9-21. Any new development shall be encouraged to generally
conform with natural contours to avoid excessive grading.
2. Zoning Consistency: The project site is currently zoned Heavy Industrial
District (H-I), which allows heavy industrial manufacturing uses of all kinds,
including, but not limited to, lumber, steel, chemicals, explosives, fertilizers, gas,
rubber, paper, cement, sugar, and all other industrial or manufacturing products
including the processing of petroleum and the manufacturing of petroleum
products (i.e. crude oil refinery). No such industrial uses, or other uses of any
kind, exist on the subject property which is entirely vacant land. The proposed
144-lot Bay View Estates Residential Project is incompatible with the current
heavy industrial zoning designation. In order to implement the subdivision, the
project includes an application to rezone the subject property (File# CDRZ04-
03148) from Heavy Industrial District (H-I) to the Bay View Estates Planned Unit
District (P-1).
3. Development Standards: The P-1 zoning designation will allow single-family
homes while setting aside land for hillside open space, storm drainage
management, a neighborhood park, and protected wetlands. Compared to the
largely unrestricted development standards of the Heavy Industrial District, the
proposed P-1 district would have reduced lot area, lot width, lot depth, and
building height requirements. The proposed development standards are
presented below in Table 1:
4. Development Plan: The proposed Preliminary and Final Development Plan
(File# CDDP04-03080) for Bayview Estates includes 144 single-family residences

that will be constructed in five basic architectural plans with four 2-story
designs and one 1-story design (Exhibit #4). Each of the five plans has three
themes (i.e. Tuscan, French Country, and Traditional), which allows for 15
different home-design variations in the subdivision.
• Plan 1 proposes approximately 2,137-square-foot, 4-bedroom, 2½ bath,
1-story homes with integrated 2-car garages.
• Plan 2 proposes approximately 2,378-square-foot, 5-bedroom plus loft,
2½ bath, 2-story homes with integrated 2-car garages.
• Plan 3 proposes approximately 2,678-square-foot, 5-bedroom (or 4-
bedroom plus loft), 2½ bath, 2-story homes with integrated 2-car
garages.
• Plan 4 proposes approximately 2,745-square-foot, 4-bedroom plus loft,
2½ bath, 2-story homes with integrated 2-car garages.
• Plan 5 proposes approximately 3,101-square-foot, 5-bedroom (or 4-
bedroom plus loft), 3½ bath, 2-story homes with integrated 2-car
garages.
A Planned Unit District (P-1) must be a residential environment of sustained
desirability and stability, and be in harmony with the character of the
surrounding neighborhood. Further, the P-1 district is intended to provide
flexibility of site design, building massing, setbacks, and height. The proposed
Bayview Estates Residential Project will set aside permanently protected open
space and wetlands that will provide potential wildlife habitat, filter and retain
stormwater runoff, and maintain and enhance the overall character of the Vine
Hill neighborhood. Thus, the proposed project would be consistent with the
surrounding neighborhood.
5. Inclusionary Housing: The inclusionary unit requirement found in Section
822-4.402 of the Affordable Housing Ordinance requires at least fifteen percent
of the for-sale units are required to be inclusionary units (i.e. units that are
required to be sold at an affordable sales price to lower and moderate income
households). The effective date of the inclusionary unit requirement was
November 23, 2006, and the project applications were deemed complete on
October 17, 2006; therefore, the project is not subject to the inclusionary unit
CPC – February 23, 2022
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 20 of 24
requirement of the Affordable Housing Ordinance.
6. Off-Street Parking: As described above in Section IX.4, each single-family
residence would have an integrated 2-car garage. Thus, resident parking would
be 2 parking spaces per lot, as shown on the proposed Preliminary and Final
Development Plan. The 2-parking space requirement is consistent with the
County’s off-street parking requirements for new single-family residences.
7. Traffic and Circulation: The project site is accessed from Palms Drive, an
existing private paved road that links to Arthur Road, a public street 1400 feet
to the west; and Central Avenue, which is a mostly paved public street, but
terminates to a private gravel road some 475 feet west of the Project site. Both
Palms Drive and Central Avenue west of the Project site currently provide two-
way passage but are generally too narrow to meet current County Public Works
standards. Off-site road improvements to Palms Drive and Central Avenue are
part of the overall project scope. Mitigation measures were identified in the
project EIR to mitigate the project’s traffic and circulation impacts. These
measures include:
• Provide continuous sidewalks on at least one side of Palms Drive to
connect the project site to the existing pedestrian facilities on Arthur
Road and to improve pedestrian transportation conditions.
• Provide continuous sidewalks on at least one side of Central Avenue to
connect the project site to the existing pedestrian facilities that terminate
approximately 100 feet east of Darcie Way to improve pedestrian
transportation conditions.
• Provide even surface pavement, appropriate signage, delineation, and
other features on Palms Drive and Central Avenue to improve bicycle
transportation conditions.
• Provide even surface pavement, appropriate signage, delineation, and
other features on Palms Drive and Central Avenue to accommodate
emergency vehicles.
• Provide sidewalks for all streets within the project site including facilities
on both sides of each street and curb ramps at each street intersection.
The applicant intends to improve these off-site roadways to meet the minimum
standards necessary to have them accepted by the County as public streets.
However, in addition to improvement of the streets, the underlying property
CPC – February 23, 2022
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 21 of 24
would have to be dedicated to the County by the fee title owner, which is an
action outside of the control of the applicant. Public Works has no objection to
the roads remaining private, but emphasizes that they should be improved to
public street standards to satisfy the project EIR mitigation requirements and
allow for the possibility of future acceptance by the County in the event that the
right of way is dedicated. It should be noted that the internal subdivision
streets shall remain private and cannot be accepted by the County as public
streets until improvement and dedication of the private road portions of Palms
Drive or Central Avenue are accepted by the County.
Exceptions to the County Ordinance Code’s street design requirements were
requested by the applicant. The exception requests were from Section 98-4.002
(Minimum Requirements) and by reference, 92-4.012 (Collector Street) and 92-
4.056 (Minor Street). Public Works has reviewed these requests relative to the
specific streets cited in the applicant’s request and have found them to be
comparable with the most recently approved project in the area, the Vinehill
Meadows subdivision adjacent to I-680. The Public Works Department has no
objection to these street configurations, with one minor exception. The
applicant requested a 44-foot wide right of way for portions of C Drive whereas
prior tentative maps (e.g. VTM dated March 26, 2020) indicated 46 feet. The 44-
foot right of way only provides 1-foot from the back of sidewalk to the top or
toe of the embankment slope, whereas the rest of the streets have 2 feet. The
additional foot will provide additional buffer to prevent undermining of the
sidewalk or sloughing of embankment material onto the sidewalk, depending
on the applicable cut or fill situation at the roadway section. The findings for
these exceptions are attached to this staff report in the project’s findings and
proposed conditions of approval.
8. Drainage: Pursuant to the County Ordinance Code, the applicant shall collect
and convey all stormwater entering and/or originating on this property,
without diversion and within an adequate storm drainage facility, to a natural
watercourse having definable bed and banks, or to an existing adequate public
storm drainage system which conveys the stormwater to a natural watercourse.
Furthermore, the applicant shall verify the adequacy of any downstream
drainage facility accepting stormwater from this project prior to discharging
runoff. The drainage plan for the project essentially collects the runoff from the
developed portions of the site into a combined detention and treatment basin
then discharges the runoff to the creek. The detention elements of the basin

CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 22 of 24
will reduce project runoff rates below the current undeveloped rates.
The applicant has requested an exception to Section 914-12.010 (Detention
Basins – Maintenance). This section requires detention basins to be maintained
by a public entity such as a Geological Hazard Abatement District (GHAD) or
Community Services District. Similar exceptions have been granted in the recent
past for these smaller detention basins. Public Works has no objection to the
granting of this exception request and the findings for these exceptions are
attached to this staff report in the project’s findings and proposed conditions of
approval.
9. Stormwater Management and Discharge Control: In compliance with
Provision C.3 of the National Pollutant Discharge Elimination System (NPDES)
Permit and the County’s Stormwater Management and Discharge Control
Ordinance (§1014), the applicant submitted a Stormwater Control Plan (SWCP)
prepared by Balance Hydrologics, dated May 29, 2020, which has been deemed
to be “preliminarily complete”. Note that the SWCP remains subject to future
revision based on any changes made during the preparation of improvement
plans to better address compliance with C.3 stormwater requirements. There
are also certain aspects of the stormwater treatment basin, such as geotechnical
stability, outlet works, maintenance access, controlled emergency overflow, etc.
that will need to be resolved as the project proceeds through final design prior
to construction. Specifically:
• The Flood Control District does not recommend construction of
bioretention basins next to creeks or other water facilities subject to
inundation as depicted on the revised Tentative Map. Due to the
potential impacts of over saturation of the creek embankment (basin
levee) and possible failure where groundwater gradients exit the creek-
bank slope, this basin location is not recommended. Therefore, prior to
allowing this configuration, a geotechnical report signed and stamped by
a registered geotechnical engineer should be provided to the County for
review. The geotechnical report should demonstrate that the through
seepage, under seepage, oversaturated soil conditions, and steep levee
side slope will not impact the basin embankment stability.
• The stability of the steep 2:1 slope embankment on the eastern side of
the development, along Drive “C” (and bioretention basin), and adjacent
to wetlands in an area prone to flooding, remains a concern to the Flood
CPC – February 23, 2022
CDGP04-00013/CDRZ04-03148/CDSD04-08809/CDDP04-03080
Page 23 of 24
Control District. Due to the impacts a failure of the proposed
embankment would have on the Pacheco Creek flood control channel
and adjacent wetlands, it is recommended that a geotechnical report
substantiating the steep embankment’s stability, signed and stamped by
a registered geotechnical engineer, be submitted to the County for
review.
10. Tree Permit: As described in Section VI. (Project Description) of this report, a
tree permit to remove up to 30 code-protected trees will be required to
accommodate the development. A valley oak woodland occurs on the north-
facing slope of the hill within the project site. Disturbance to this valley oak
woodland may be necessary during grading and may require removal of
approximately 30 trees. The oak woodland is considered a sensitive natural
community by California Department of Fish & Wildlife for its local rarity.
Additionally, valley oak, coast live oak, and California bay trees on the hill are
protected under the Contra Costa County Tree Protection and Preservation
Ordinance. Permanent impact to this valley oak woodland community as a
result of the project through removal of protected trees is potentially
significant. Accordingly, the project EIR identified measures to mitigate the
project’s impact on trees to a less-than-significant level that include the
following:
• Planting replacement trees within the project site on areas of the hill that
will be preserved as open space following development. The project
sponsor shall contract with a qualified restoration ecologist to prepare a
Habitat Mitigation and Monitoring Plan (HMMP) for oak woodland
habitat to be restored as part of the project. The HMMP would be
subject to approval by Contra Costa County.
• Paying an in-lieu fee to a natural resource agency or a non-profit
organization that would use the fees to protect or enhance oak woodland
habitat of the region. The amount of an in-lieu fee will be determined
either by calculating the value of the land with oak woodland habitat
proposed for removal, or by some other calculation. An alternate
calculation shall reflect differences in the quality of habitat proposed for
removal and may consider the cost of comparable habitat (fee title or
easement) in nearby areas. The amount of the in-lieu fee and the entity
receiving the funds shall be subject to review and approval by the County.

The full mitigation measures cited in the project EIR for tree removal and
restitution are included as conditions of approval for the project. Staff
recommends approval of the tree permit and the findings for approval of a tree
permit are attached to this staff report in the project’s findings and proposed
conditions of approval.
X. CONCLUSION
The proposed Bayview Estates Residential Project would be consistent with the
proposed Single-Family Residential-High Density (SH) General Plan land use
designation (File# CDGP04-00013), and as conditioned, would be consistent with
the applicable goals and policies of the General Plan. The Subdivision (File#
CDSD04-08809) would provide 144 single-family-residential home sites on the
subject property and set aside permanently protected open space and wetlands
that would provide potential wildlife habitat, filter and retain stormwater runoff.
The proposed Rezoning (File# CDRZ04-03148) would establish a P-1 Planned Unit
District that would facilitate development of the 144 single-family residences. The
proposed residences would be constructed pursuant to the proposed Preliminary
and Final Development Plan (File# CDDP04-03080), which reflects the proposed
development standards for the Bayview Estates Planned Unit District. As such, the
proposed project would be consistent with the surrounding neighborhood. Staff
therefore recommends that the County Planning Commission approve Subdivision
CDSD04-08809 and the proposed Preliminary and Final Development Plan
CDDP04-03080. Staff also requests that the Planning Commission recommend
approval by the Board of Supervisors of the proposed General Plan Amendment
CDGP04-00013 and Rezoning CDRZ04-03148.

COMMUNITY BENEFITS AGREEMENT
between
CONTRA COSTA COUNTY and
DISCOVERY BUILDERS INC.
(County File Nos. CDGP04-00013, CDRZ04-03148, CDSD04-08809, CDDP04-03080)
This Community Benefits Agreement (“Agreement”) is entered into as of _____________, 2022
(“Effective Date”) by and between Contra Costa County (“County”), a political subdivision of the
State of California, and Discovery Builders Inc. (“Developer”), a California corporation.
RECITALS
A. On_________, 2022, the County Board of Supervisors certified the environmental impact
report and approved Developer’s Bayview Estates Residential Project (the “Project”), a 144-unit
single-family residential development located in the unincorporated Vine Hill/Pacheco area, including
a General Plan amendment (CDGP04-00013), a rezoning (CDRZ04-03148), a vesting tentative map
(CDSD04-08809), and a preliminary and final development plan (CDDP04-03080).
B. In addition to the discretionary land use approvals already obtained from the County,
Developer intends to obtain County building permits necessary to construct the Project.
C. The County seeks to repair its sidewalks and related pedestrian improvements from the
intersection of Arthur Road, Palms Drive, and Leabig Lane to and including the pathway from Karen
Lane to Las Juntas Elementary School, which will facilitate implementation of polices set forth in the
County's Safe Route to School Program.
D. The Project approval contains Condition of Approval No. ___ that requires Developer to
design and construct sidewalk and path improvements and enhanced pedestrian crosswalks along
Arthur Road and Karen Lane from the intersection of Arthur Road, Leabig Lane, and Palms Drive to
and including the pathway from Karen Lane to Las Juntas Elementary School (collectively, the
“Enhanced Pedestrian Improvements”). Construction of the Enhanced Pedestrian Improvements is
required to be completed prior to issuance of a building permit for the Project’s 49th residential unit.
However, the Director of Conservation and Development (the “Director”) may authorize the issuance
of additional building permits before the Enhanced Pedestrian Improvements are completed.
E. Due to its location and surrounding uses, the Project is a unique residential development
with unique impacts on the community.
AGREEMENT
NOW THEREFORE, Contra Costa County and Developer agree as follows:
1. Purpose. The purpose of this Agreement is to memorialize Developer’s commitment to making
2
a community benefits contribution to the County on a per-residential unit basis as building
permits are issued for residential units of the Project. The foregoing recitals are correct and
incorporated by reference into the Agreement terms.
2. Community Benefits Payments.
a. Developer shall pay $2,000,000 to the County, less the actual design, construction,
and other costs incurred by Developer to complete the Enhanced Pedestrian Improvements (in
total, the “CB Amount”).
b. Developer shall pay the CB Amount, including all CPI increases to the CB Amount,
on a per-residential unit basis as follows:
i. For each building permit issued by the County for the Project, up to and
including the building permit for the Project’s 48th residential unit, Developer shall make a
payment of $10,417, plus the applicable CPI increase (each an “Initial CB Payment”). The
parties acknowledge that this calculation of the Initial CB Payment assumes that the actual
costs incurred by Developer to complete the Enhanced Pedestrian Improvements will be
$500,000, and that the true actual costs (whether greater or less than $500,000) will be
accounted for in the calculation of the Recalculated CB Payment below.
ii. If the Director authorizes the issuance of additional building permits after
the building permit for the Project’s 48th residential unit is issued but before the Enhanced
Pedestrian Improvements are completed (each, an “Additional Building Permit”), Developer
shall pay an Initial CB Payment to the County for each Additional Building Permit issued by
the County.
iii. Beginning with the building permit issued for the Project’s 49th residential
unit, or the first building permit issued after the Enhanced Pedestrian Improvements are
completed, whichever occurs later, and for each subsequent building permit, Developer shall
make a payment equal to the following (each a “Recalculated CB Payment”):
��Principal amount of the CBA Amount remaining unpaid�−�Actual cost incurred by Developer to completethe Enhanced Pedestrian Improvements ���96 − �Number of Additional Building Permitsissued by the County,if any ��
c. Beginning on January 1, 2024, and on each January 1 thereafter, the principal
amount of the CB Amount remaining unpaid, if any, shall increase by any increase in the
Consumer Price Index for the San Francisco-Oakland-Hayward Combined Statistical Area
(U.S. Bureau of Labor Statistics) for the 12-month period ending on the October 31
immediately preceding the January 1 when the increase takes effect.
d. Developer may pre-pay all or any portion of the CB Amount, plus the applicable
CPI increase, without penalty.
3
3. Verification of Developer’s Actual Costs. When the Enhanced Pedestrian Improvements are
completed, Developer shall provide the County with documentation of the actual costs incurred
by Developer, including but not limited to, an accounting of contracts executed, purchases
made, and developer’s staff time spent to design, construct, and otherwise complete of the
Enhanced Pedestrian Improvements. At the County’s request, Developer shall provide
additional documentation or information necessary for the County to calculate the Recalculated
CB Payment amount.
4. Use of Payments. The County shall, in its sole discretion, allocate funds received pursuant to
this Agreement to benefit the local community.
5. Notices. All payments, notices, demands, and other communications made under this
Agreement shall be in writing and personally delivered, sent by overnight carrier with delivery
charges prepaid for next business day delivery, or sent by First Class U.S. Mail with postage
prepaid, and addressed as follows:

County
Subject:Contra Costa County Active Transportation Plan Final Report, Countywide.
BACKGROUND:
The Active Transportation Plan (ATP) demonstrates that Contra Costa County is committed to enhancing active transportation by
promoting access and connectivity for all modes of travel besides automobile travel. By definition, active transportation comprises any
self-propelled, human-powered travel, such as walking and bicycling. The purpose of Contra Costa County’s ATP is to serve as a roadmap
to enhance active transportation safety and mode share for unincorporated areas in Contra Costa County by providing a comprehensive look
at the County’s active transportation needs and opportunities. The plan outlines investments in new bicycle facilities, upgraded crossings,
enhanced trail connections, and improved walkways. These investments prioritize improvements within historically underserved and
impacted communities. The ATP Final Report is the culmination of three years of effort by County staff and their consultants.
The process of developing this ATP began with documenting community needs and input and builds off the County’s efforts in the recently
adopted Vision Zero Action Plan. The Vision Zero Action Plan includes a systemic look at safety and collision history within the County,
including improvements for bicyclists and pedestrians. This ATP is intended to serve as an implementing action of the Vision Zero Action
Plan, as well as guide future grant applications and funding for active transportation projects that support mode shift to walking and
bicycling. Additionally, this ATP is consistent with other documents such as the County’s General Plan, the County’s Complete Streets
Policy, Plan Bay Area 2050, Contra Costa Transportation Authority’s (CCTA) Countywide Bicycle and Pedestrian Plan, and the County’s
Climate Action Plan.
The ATP’s vision statement is as follows: Contra Costa County will have an equitable transportation system that supports active
transportation for users of all ages and abilities, allowing all to travel conveniently, reliably, and free from harm.
The goals and objectives for the ATP were developed in support of this vision and with consideration of other local and State plans and
policies, desires of local residents, and emerging trends and opportunities in active transportation. This ATP was created to facilitate the
following goals:
Prioritize active transportation investments based on factors such as collision history or systemic risk,
location in an impacted community, location near key destinations, and funding opportunities.
1.
Shift trip modes by Contra Costa County residents and visitors from motor vehicles to active modes such as
walking and biking to create a more sustainable community and reduce greenhouse gas emissions.
2.
Provide a vision for arterials and collectors within the unincorporated County roadway network to assist
County departments in planning for private development, capital projects, and maintenance efforts.
3.
Obtaining input from Contra Costa County residents was an important component of the ATP development process. A project website was
created and a number of community engagement tools were utilized to gather feedback from a wide range of residents with an emphasis on
high-priority areas within the County. Community participation was solicited via targeted social media ads, community meetings, pop-up
engagement events, sidewalk decals directing residents to the project website, virtual community workshops, online survey, and interactive
web map.
The projects proposed in the ATP were developed and prioritized based on a variety of factors such as: fatal or severely injured collision
history, projects within CCTA’s Pedestrian Priority Areas, projects along CCTA’s Bicycle Backbone Network, recommendations from
previous regional efforts, feedback from key stakeholders and the community, proximity to key destinations (e.g., schools, hospitals,
affordable housing, transit stops, parks), projects within impacted areas as defined by multiple resources (i.e. Metropolitan Transportation
Commission’s Equity Priority Areas, Healthy Places Index, CalEnviroScreen, American Community Survey data, Community Air Risk
Evaluation Program, and the California Department of Education), and ease of constructability.
Given the scope of projects within this ATP, implementation will take many years to complete. Implementation of each project is dependent
upon the availability and acquisition of funding. The County will periodically update this plan, ideally on a five-year timeline, to reflect
evolving needs and progress toward completion.
On March 14, 2022, the Transportation Water and Infrastructure Committee (TWIC) accepted the draft of the Active Transportation Plan
Report, dated March 2022, and directed Public Works staff to incorporate comments and present to the full Board of Supervisors for
adoption. Since then this report has been updated and the Final Report is dated April 2022.
CONSEQUENCE OF NEGATIVE ACTION:
Failure to adopt the Active Transportation Plan Final Report will impact the competitiveness of the County in securing granting funding
from multiple grant programs such as the Active Transportation Program and One Bay Area Grant Program.

EXECUTIVE SUMMARY
2 Contra Costa County Active Transportation Plan
The Contra Costa County Active
Transportation Plan (ATP)
provides a comprehensive look
at the needs and opportunities
to improve bicycling and
walking throughout the
unincorporated areas of the
County. The plan outlines
investments in new bicycle
facilities, upgraded crossings,
enhanced trail connections,
and improved walkways.
These investments prioritize
improvements within historically
underserved and impacted
communities.
The process of developing this
Plan began with documenting
community needs and input,
and builds off the County’s
efforts in the recently adopted
Vision Zero Action Plan. The
Action Plan included a systemic
look at safety and collision
history within the County,
including improvements for
bicyclists and pedestrians.
This Plan is intended to serve
as an implementing action of
the Vision Zero Action Plan, as
well as guide future grant and
funding applications for active
transportation projects that
support mode shift to walking
and bicycling.
The Plan includes:
• An introduction to the
project and overview of
unincorporated Contra Costa
County (Chapter 1)
• A guiding vision statement
with associated goals and
actions (Chapter 2)
• A review of the existing
conditions for bicycling and
walking within the County
(Chapter 3)
• Detailed feedback from
multiple phases of public
outreach and engagement
(Chapter 4)
• An overview of projects
and programs designed to
respond to community input
and prioritize investments
where they’re needed most
(Chapter 5)
• A set of seven project
groupings for priority
implementation, along
with cost, construction,
and funding implications
(Chapter 6)
In support of the County’s goals
for sustainability, safety for all
road users, economic vitality,
and equitable investment, the
projects and programs in this
Plan represent an exciting and
critical set of opportunities for
the County’s first-ever Active
Transportation Plan.

INTRODUCTION
7Contra Costa County Active Transportation Plan
Purpose of this Plan
The Contra Costa County Active
Transportation Plan (ATP )
will serve as a roadmap to
enhance active transportation
safety and mode share for
the unincorporated areas in
Contra Costa County. Active
transportation is any self-
propelled, human-powered
travel, such as walking and
bicycling. By prioritizing active
transportation, Contra Costa
County hopes to create a
more sustainable and healthy
community and reduce
greenhouse gas emissions.
Parallel to this Plan is the
development of the County’s
Vision Zero Action Plan (CCC
Vision Zero Plan). By embracing
Vision Zero, the County is
committed to the elimination
of severe injuries and fatalities
resulting from traffic collisions
on County roadways. The CCC
Vision Zero Plan focuses on a
range of policies, programs, and
practices that support the Safe
System approach.
Embracing the Safe System
approach as part of this ATP
aligns with the 2022 National
Safety Strategy released by the
US DOT1, and Caltrans’ pivot
in their safety philosophy and
commitment with the most
recent Strategic Highway
Safety Plan. Committing to
and providing a Safe System,

Brochure_V9_508_200717.pdf
especially for vulnerable road
users, is a foundational need for
the County. This Plan reinforces
this notion and adds additional
opportunities for mode shift
to active uses building on that
baseline of safe mobility.
8 Contra Costa County Active Transportation Plan
What Are Complete Streets?
Complete Streets are designed to prioritize safety, comfort, and
access to destinations for all users and modes of travel. Complete
Streets are unique to a community’s context and the needs of
the surrounding area. A complete street design often balances
benefits for those walking, biking, and taking transit, including
improvements such as safety enhancements at crosswalks, better
bus stop waiting areas, and enhanced bicycle facilities.
This Plan, the first of its kind for
the County, presents a major
opportunity for the County to
enhance the existing multimodal
transportation network by
integrating bicycle, pedestrian,
safe routes to school, and
accessibility improvements using
a Complete Streets approach.
The County ATP builds upon
many elements that help
make the County an exciting
destination for residents and
businesses, as well as the many
visitors to the region.
Just as many factors influence
how travelers behave, numerous
factors influence what actions
an agency can take. While this
effort is focused on bicycle,
pedestrian, ADA, and safe
routes to school planning,
considerations have been made
related to economic vitality,
efficient movement of goods/
people, public health, and
ecological challenges.
Facilitating an increase in
walking and biking can confer
a variety of benefits such as
reduced congestion, improved
safety, comfort, health, air
quality, economic vitality, and
quality of life. Increased walking
and bicycling will also support
the County’s requirements under
new regulatory frameworks,
including mandates to reduce
greenhouse gases and vehicle
miles traveled (VMT).
Benefits of Active
Transportation
Walking, biking, and rolling are
transportation methods integral
to the health of individuals and
communities. The benefits of
active transportation include
the following:
• Connects families to schools,
parks, work, shopping,
restaurants, and bus stops,
as well as other members of
the community
• Improves health and reduces
the incidence of disease and
obesity
• Reduces air pollution and
greenhouse gas production
• Supports local businesses
and economic vitality
• Creates more vibrant and
lively streets
• Saves money on gas and car
maintenance
9Contra Costa County Active Transportation Plan
Environment
By enabling people to make
short trips on foot or bicycle
instead of a car, active
transportation can help
communities address several
environmental challenges. The
most discussed, and perhaps
most critical, environmental
benefits of active transportation
are reduced air pollution and
emissions of greenhouse
gases. Current data show that
the transportation system is
responsible for approximately
40% of the greenhouse gas
emissions in California.2 Other
environmental benefits include
energy savings, less noise
pollution, less water pollution,
and even reduced pressure to
develop agricultural and open
space.

Vol-1.2017.10.05.pdf, pg ES-6.
Mobility
Active transportation gives
people who cannot or
choose not to drive more
and affordable options for
getting around independently
to meet their daily needs.
Those who benefit most from
improvements to walking
and biking include children
(particularly for going to
school); many seniors and
people with disabilities; and
low-income families, for
whom the cost of owning
and operating a car can be
prohibitive.
Transportation options are
also important for drivers who
would like to spend less time
behind the wheel shuttling
themselves or others around.
Drivers also benefit from less
congestion, less demand for
parking, and fewer vehicle miles
traveled (VMT) when more
people walk and bicycle. Even a
small number of people shifting
their mode choice to walking
and biking can have a positive
impact on reducing traffic
congestion.
Health
Active transportation allows
people to build physical activity
into everyday life by enabling
them to walk or bike to their
destination(s). Even a moderate
amount of daily exercise
offers an impressive range of
benefits to both physical and
mental health. These benefits
range from lower risk of heart
disease, adult-onset diabetes,
high-blood pressure, and stress
to more energy, flexibility,
and muscle strength. Physical
activity can also help combat
obesity and lower asthma rates.
Livability
Promoting active transportation
leads people to walk and bike
more and to drive less, which
can improve quality of life in
important ways. When residents
are out on foot or on bike, they
interact more with neighbors.
Residential streets become
calmer and quieter, encouraging
community interaction. Streets
become not only safer, but
also livelier with an increased
presence of pedestrian and
bicycle traffic.
10 Contra Costa County Active Transportation Plan
Equity
Active transportation can
benefit the bottom line of
households, businesses, and
cities. The economic benefits
of walking and biking include
lower transportation costs
for individuals and families,
increased property values in
traffic-calmed neighborhoods,
savings to cities from less
wear and tear on streets,
less demand for roadway
improvements and parking
lots, and a greater ability for
communities to attract new
residents and employers.

Public
Participation
Obtaining input from Contra
Costa County residents was
an important piece of the ATP
development process. A project
website was created and
community workshops were
held to solicit feedback on high
priority areas within the County.
Community participation was
solicited through the following:
• An interactive project
website to promote outreach
and educational materials,
document workshops and
events, host the online
survey and interactive map,
and allow the public to
provide feedback on the
draft plan
• A Public Engagement Plan
with trusted community
organizations to engage
on the County’s impacted
communities, non-English
speaking households, people
without Internet access,
and other hard-to-reach
populations
• Targeted community
meetings to discuss key
issues around active
transportation relevant to
each organization or group’s
mission
• Pop-up engagement
events that included
engagement toolboxes
on educational materials,
project information, event
flyers, and culturally relevant
engagement activities, along
with mobile workshops to
understand community-
specific needs and increase
public visibility and
understanding of the Plan
• Four community workshops
to receive feedback on the
Plan at all stages of analysis
and recommendations
Full details on the public
participation process and
outcomes can be found in
Chapter 4.

About Contra
Costa County
Unincorporated Contra Costa
County is a dispersed set of
urban, suburban, and rural
communities spread throughout
Contra Costa County. Contra
Costa County is broadly divided
into three sub-regions, and the
unincorporated areas include
the following communities, as
shown on Figure 2:
• West County — Kensington,
El Sobrante, North
Richmond, Rodeo, Crockett,
Port Costa, Bayview-
Montalvin, East Richmond
Heights, Rollingwood,
Tara Hills
• Central County — Canyon,
Pacheco, Vine Hill, Clyde,
Contra Costa Centre

Mountain View
• East County — Bay Point,
Bethel Island, Knightsen,
Discovery Bay, Byron
Contra Costa County’s
landscape is widely varied,
and in most places generally
suburban and rural in character.
The estimated countywide
population is 1,165,927,
according to the U.S. Census
Bureau (2020). Of this total
population, approximately
174,000 residents live in
unincorporated areas. A
demographic assessment
reveals the following:
• Contra Costa County is
racially diverse: About
26% of the population
identifies as Hispanic or
Latinx, 9% as Black, and
18% as Asian. Communities
with populations of over
70% people of color include
North Richmond, Bay Point,
and Tara Hills.
• Contra Costa County is
linguistically diverse: Large
Hispanic/Latinx populations
are located in both North
Richmond (54%) and Bay
Point (58%), where more
than 20% of people have
limited English proficiency.3
• Contra Costa County has
high income inequality:
The median income in
unincorporated Contra Costa
is $132,600, which is higher
than Contra Costa County
as a whole ($99,716).4
However, 16% of people
in unincorporated Contra
Costa are low income, with
38% of those low-income
residents living in low-
income communities where
more than 28% of people
are below 200% of the
3 The Metropolitan Transportation
Commission defines Limited English
Proficiency as a person above the age
of five years, who do not speak English
at least “well” as their primary language
or had a limited ability to read, speak,
write, or understand English at least
“well,” as defined by the U.S. Census.

federal poverty level.5 The
highest concentrations of
poverty in Contra Costa
County are located in just
a few neighborhoods,
including North Richmond,
Rodeo, and Bay Point. The
median incomes in these
communities are all less than
the threshold of 80% of the
state median income, or
$60,200.
5 MTC defines low income as a person
living in a household with incomes less
than 200% of the federal poverty level
established by the Census Bureau. A
community is considered low income
when 28% or more of people in the
census tract meet this definition.

• Many Contra Costa County
residents get around
by car: In Contra Costa
County overall, 98% of
households have access to
an automobile. However,
in a few neighborhoods
in unincorporated Contra
Costa County, that number
is much lower. In Bay Point
and Rodeo, for example,
9-10% of households have
no vehicle access. These
numbers are significantly
above countywide and Bay
Area region-wide averages
and indicates a high need
for active transportation
and public transportation to
facilitate equitable mobility.
Key Destinations
and Land Uses

Impacted
Communities
Service to historically
marginalized and underserved
communities is a key factor in
many grant funding programs
such as California’s Active
Transportation Program. This
plan presents four different
indicators of impacted
communities6, often referred
to as environmental justice
communities.
• Household median income
– census tracts with median
household income less than
80% of the statewide median,
of $60,188 (American
Community Survey (ACS)
2015-2019) (Figure 4)
• Free or reduced-price meal
eligibility – the share of
students at a school who
are eligible for subsidized
meals. Schools with at least
75% eligible students are
considered disadvantaged
by the Active Transportation
Program’s guidelines (Figure
5)
• CalEnviroScreen 4.0 score
percentile – a measure of
environmental health by
census tract. Inputs include
socioeconomic factors,
population characteristics,
pollution factors, and
environmental factors. Tracts
with higher percentiles
are more disadvantaged.
The worst scoring 25% are
considered disadvantaged

VISION AND
GOALS
23Contra Costa County Active Transportation Plan
Vision Statement
Contra Costa County will have an
equitable transportation system
that supports active transportation
for users of all ages and abilities,
allowing all to travel conveniently,
reliably, and free from harm.
The goals and objectives for this plan
were developed in support of this
Vision and with consideration of other
local and state plans and policies,
desires of local residents, and emerging
best practices and opportunities in
active transportation. The County’s
General Plan, Vision Zero Plan, the
Contra Costa Transportation Authority’s
(CCTA) 2018 Countywide Bicycle
and Pedestrian Plan (2018 CBPP),
and CCTA’s Vision Zero Framework
& Systemic Safety Approach (Vision
Zero Framework) each have goals
supporting increases in bicycling and
walking. Other statewide plans include
the California Transportation Plan
and the California State Bicycle and
Pedestrian Plan. The MTC Regional
Active Transportation Plan is currently
under development, and will be an
additional resource once published.
Goals and Actions
This plan was created to help facilitate the
following goals and actions. 1 Prioritize active transportation investments based
on factors such as collision history or systemic risk,
location in an impacted community, location near key
destinations, and funding opportunities.
Action 1-1: Use the High-Injury Network (HIN) to
identify hot spots and systemic risks to apply for grant
funding to implement projects prioritizing impacted
communities’ access to key destinations
Action 1-2: Enhance equity for communities that
have seen less infrastructure investment and are
disproportionately impacted by collisions
Action 1-3: Support neighborhood retail and local
business vitality through projects that connect to and
through key destinations
24 Contra Costa County Active Transportation Plan
Shift trip modes by Contra Costa County
residents and visitors from motor vehicles to
active modes such as walking and biking to
create a more sustainable community and
reduce greenhouse gas emissions.
Action 2-1: Enable children to walk and bike
to school by providing safe and accessible
routes to school
Action 2-2: Fill key gaps in the network by
providing first/last mile connections and
reducing the stress level at crossings and
interchanges
Action 2-3: Implement Class IV bike lanes,
also known as protected or separated
bicycle facilities. This physical separation of
bicyclists from motor vehicles can reduce the
level of stress, improve comfort for all users,
and contribute to an increase in mode shift.
2 Provide a vision for arterials and collectors
within the unincorporated County roadway
network to assist County departments in
planning for private development, capital
projects, and maintenance efforts.
Action 3-1: Commit to Complete Streets and
Safe System approaches and clarify how
existing County procedures, policies, and
plans may conflict
Action 3-2: Collaborate with key County
stakeholders, neighboring jurisdictions,
and Caltrans for larger funding efforts
to complement infrastructure with non-
infrastructure projects and create regionally
significant projects

Bicycle and
Pedestrian
Networks
Currently, Contra Costa County
has 25.1 miles of shared-use,
off-street paths, 56.4 miles of
roadway with designated bicycle
facilities, and 440.6 miles of
sidewalks in unincorporated
areas. These networks are
summarized in Table 1 and
mapped in Figure 8.

modes are employed and
enjoyed by the community and
visitors to Contra Costa County.
Throughout this document,
all references to pedestrians
are inclusive of persons with
disabilities who use mobility
aids (scooters, manual and
powered wheelchairs) to access
public pedestrian walkways.
The County’s existing roadway
network primarily serves
vehicular traffic for regional
routes of significance. Bicycle
and pedestrian networks
often have gaps where
unincorporated Contra
Costa County meets various
incorporated jurisdictions.

Existing Bicycle
Facilities
Cities and counties around the
Bay Area and nationwide are
using a “level of traffic stress”
(LTS) analysis to help determine
the comfort of bicycling in
their communities. An LTS
analysis takes different travel
corridor characteristics into
consideration, including the
number of travel lanes; speed
of traffic; number of vehicles;
presence of bike lanes; width
of bike lanes; and presence
of physical barriers providing
protection from traffic. Based
on these variables, a bicycle
facility can be rated with an LTS
ranging from 1 to 4.
The least stressful (most
comfortable) facilities are given
an LTS 1 rating. Facilities with
this rating are typically shared-
use paths; separated bikeways;
low-volume and low-speed bike
routes; and bike lanes on calm
and narrow streets. The most
stressful (least comfortable)
facilities are given an LTS 4
rating. Facilities with this rating
are typically major arterials with
multiple lanes of traffic (with or
without bicycle lanes in some
cases, depending on speeds)
or narrower streets with higher
speed limits.
The 2018 CBPP7 further details
a low-stress Countywide
Bikeway Network (CBN), that
when implemented, will provide
connected facilities to serve
all ages and abilities, address
the barriers created by high-
stress arterials and collectors,
and provide key connections
between destinations and
infrastructure for local bikeways.
Furthermore, the 2018 CBPP
also includes an LTS analysis of
how the implementation of the
CBN would increase the existing
149 miles of low-stress facilities
to 513 miles of low-stress
facilities countywide.

Contra Costa County’s existing
and proposed bikeway network
consists of four primary
bikeway types, as classified in
Chapter 1000 of the Caltrans
Highway Design Manual (2015).
• Bike Paths and Shared-Use
Paths (Class I)
• Standard Bike Lanes and
Buffered Bike Lanes (Class II)

Bike Paths and Shared-Use
Paths (Class I)
Bike paths and shared-use
paths provide a separate right-
of-way for the exclusive use
of bicyclists and pedestrians.
They tend to have minimal
cross-traffic and are often
located along creeks, canals,
and former rail lines. Bike paths
are considered the lowest stress
facilities for bicyclists.
The Iron Horse Trail, the
Delta de Anza Trail, and the
Bay Trail are major regional
shared-use paths that link
unincorporated Contra Costa
County communities with
neighboring cities, recreation
areas, and regional transit. In
several locations, like the Iron
Horse Trail crossing of Treat
Boulevard, grade-separated
crossings provide access across
barriers. Other smaller trail
segments like the Wildcat Creek
Trail and the Rodeo Creek Trail
provide access and connectivity
within neighborhoods.

32 Contra Costa County Active Transportation Plan
Standard Bike Lanes (Class II)
Standard bike lanes designate
an exclusive space for bicyclists
using pavement markings and
signage. The bike lane is located
adjacent to motor vehicle travel
lanes and flows in the same
direction as motor vehicle
traffic. Bike lanes are typically
on the right side of the street,
between the adjacent travel
lane and curb, road edge, or
travel lane.
Within Contra Costa County
bike lanes are striped on
many streets, such as Fred
Jackson Way, Willow Pass
Road, Pacheco Boulevard, and
Danville Boulevard.

33Contra Costa County Active Transportation Plan
Buffered Bike Lanes (Class IIB)
Buffered bike lanes are
standard bike lanes paired with
a designated buffer space,
separating the bicycle lane
from the adjacent motor vehicle
travel lane and/or parking lane.
This type of bikeway provides
greater distance between
vehicles and bicycles; provides
space for bicyclists to pass each
other; provides greater space
for bicycling without making
the bike lane appear so wide
that it might be mistaken for
a travel lane; and encourages
bicycling by contributing to the
perception of safety.
Contra Costa County currently
installs bike lanes with buffers
where space allows, for instance
along Oak Road, Pacheco
Boulevard in front of Las Juntas
Elementary, and Bailey Road.
Class IIB buffered bike

Elementary School on
Pacheco Boulevard
34 Contra Costa County Active Transportation Plan
Bike Routes and Boulevards
(Class III and Class IIIB)
Bike routes are designated
streets where bicyclists
and automobile drivers are
encouraged to share the
road. The routes are typically
designated with signage,
but some streets also use
sharrows to indicate where
bicyclists should position
themselves on the road.
Bike routes are typically used
where there is not enough
right-of-way to provide a
standard bike lane, or along
low-volume, low-speed
streets where bicyclists can
comfortably share the road
with automobile drivers. The
County has installed Class III
bike routes as appropriate
throughout the County, for
instance Oak Road, Blackhawk
Road, and Rollingwood Drive.
Class IIIB bicycle boulevards
are similar to Class III bike
routes, in that they are
routes shared with auto
traffic. Bicycle boulevards
are primarily on low-speed
and low-volume streets
and can close important
gaps in the bicycle network
with insufficient space for
dedicated lanes. Bicycle
boulevards provide further
enhancements to bike routes
to encourage slow speeds and
discourage non-local vehicle
traffic via traffic diverters,
chicanes, traffic circles, and/
or speed tables. Bicycle
boulevards can also feature
special wayfinding signage to
nearby destinations or other
bikeways.
In Contra Costa, rural
roads that are popular for
recreational cycling are
designated as Class III bicycle
routes. No routes are currently
designated and designed as
bicycle boulevards, but many
neighborhoods streets in the
County are good candidates,
where traffic calming and
wayfinding could help
encourage bicycling for local
trips.

Separated Bikeways/Cycletrack
(Class IV)
Separated bikeways are often referred
to as “cycle tracks” and they are
a relatively newer class of bicycle
facility. They have different forms but
all share common elements—they
provide space that is intended to
be exclusively or primarily used for
bicycles, and are physically separated
from motor vehicle travel lanes,
parking lanes, and sidewalks with a
vertical element.
Separated bikeways may be one-way
or two-way and may be at street level
or at sidewalk level. If at sidewalk level,
a curb or median separates it from
motor traffic, while different pavement
color/ texture separates it from the
sidewalk. If at street level, it can be
separated from motor traffic by raised
medians, on-street parking, or bollards.
Separated bikeways provide dedicated
and protected space for bicycling
making them an attractive facility
for riders of all ages and abilities. No
Class IV bike lanes currently exist in
unincorporated Contra Costa County,
but future opportunities are being
considered where it is contextually
appropriate.

Bicycle Parking
Bicycle parking encourages
bicycling by supporting
the final stage of the trip.
Locations with high ridership
are excellent candidates
for bicycle parking: these
destinations include civic,
residential, commercial,
and office spaces. At these
locations, both short-term
and long-term parking should
be accommodated.
Short-term bicycle parking
is temporary bicycle parking
intended for visitors. Bicycle
racks are a common form
of short-term parking and
are typically located in front
of stores and other well-lit
locations to discourage theft.
Installing permanent bicycle
racks near main entrances
also helps bicyclists feel
welcome and encourages
them to ride their bicycle
again on a return trip. Bicycle
racks that allow at least two
points of contact, such as the
wheel and frame, provide the
most protection against theft
and accidental damage.
Long-term bicycle parking
is intended for employees,
students, commuters, and
residents to protect bicycles for
extended periods. Long-term
facilities are more secure and
provide protection from weather
elements. Long-term bicycle
parking includes bike lockers,
bike cages, and bike rooms. These
facilities would likely require a
third party to install and maintain.
• Bike cages are fully enclosed,
roofed shelters that house
racks of bicycle parking,
typically found at schools.
• Bike lockers are outdoor
enclosures that accommodate
one or two bicycles and are
usually leased monthly or paid
short-term use.
• Bicycle rooms are commonly
found inside office or
residential buildings and
provide secure indoor parking.
They may feature amenities
such as bike pumps and quick-
fix tools for employees and
residents.

Attitudes Towards Bicycling
People typically fall into one
of the following categories as
bicyclists:
• Strong and Fearless People
in this group are highly
skilled and have the most
riding experience. They will
use their bicycles on arterials
even when there are no
bikeways present. Studies
suggest that “strong and
fearless” riders represent
less than 1% of people in a
community. This group of
riders will feel comfortable
using facilities with any LTS
rating.
• Enthused and Confident
This group consists of
skilled riders who are also
comfortable sharing the road
but prefer using bikeways
when they are available.
“Enthused and confident”
riders make up about 7% of
people in a community. They
typically feel comfortable
using facilities with an LTS
rating of 1, 2, or 3.
• Interested but Concerned
This group of people is
curious about bicycling
and enjoys riding, but are
concerned about safety
and therefore do not ride
regularly. They typically
avoid riding their bicycles on
major arterials unless there
are facilities that provide a
high degree of protection.
“Interested but concerned”
riders represent the majority
in a community (around
60%). Riders in this group
may only feel comfortable
using facilities with an LTS
rating of 1 or 2.
• No Way No How People
in this group are simply
not interested in riding a
bicycle. Riding a bicycle
may not appeal to them for
several reasons. It may be
inconvenient, or they may
not be physically able to
ride. This group represents
approximately 33% of people
in a community.

“Revisiting the Four Types of Cyclists:
Findings from a National Survey,”
Transportation Research Record:
Journal of the Transportation Research
Board, 2587: 90-99, 2016.
These categories are explored
further in Figure 10.
Addressing comfort is one
of the most important things
any community can do
to create a more bicycle-
friendly environment. Several
studies have shown that a
community’s interest in biking
can be increased by providing
comfortable streets with lower-
stress environments.8

Existing Pedestrian
Facilities
Pedestrian facilities include
shared-use facilities, sidewalks,
and crosswalks.
Shared-Use Facilities
Class I bikeways, frequently
known as shared-use paths
or trails, are shared by both
pedestrians and cyclists. These
facilities are described earlier in
this chapter.
Sidewalks
Sidewalks are paved areas
immediately adjacent to the
vehicular right-of-way for the
exclusive use of pedestrians and
may be used by people riding
bicycles unless prohibited.
Existing sidewalks in the
county may include concrete,
asphalt, or decomposed granite
surfaces. Unlike shared-use
paths, they are directly adjacent
to the main right-of-way.
include adding pedestrian
countdowns during the
“Flash Don’t Walk” signal
phase; providing the walk
phase during each signal
cycle without having to
press the push button (also
referred to as “pedestrian
recall”); prohibiting right turn
on red; and automatically
giving pedestrians a leading
pedestrian interval (LPI) at
crossings.
• Uncontrolled: This is a type
of crosswalk that is not
located at stop-signs or
traffic signals. In some cases,
uncontrolled crosswalks are
also found in the middle of
a larger block to provide
quicker access between
streets.
• Sharks teeth, or yield
markings, are typically
installed before a marked
crossing to notify motorists
to stop and yield to
pedestrians
Crosswalks
A legal crosswalk, whether
marked or unmarked, in
California is designed as the
extension of the sidewalk as a
desire line across the road at an
intersection. Marked crosswalks
feature striping and other
enhancements to delineate a
street crossing for pedestrians.
Two types of marked crosswalks
include:
• Controlled: This type of
crosswalk is located at stop-
signs and traffic signals.
They provide the most
protection for pedestrians
since they require drivers
to come to a complete
stop for to people in the
crosswalk. Opportunities
for enhancement may

• Pleasant Hill/Contra Costa
Centre Station The Pleasant
Hill/Contra Costa Centre
Station is located in a pocket
of unincorporated County,
just north of Walnut Creek
and east of Pleasant Hill.
This station is within a half-
mile of Interstate 680 and
the regional Iron Horse Trail
and serves as a hub for
various transit providers
serving the Bay Area. The
various apartments, retail
spaces, and commercial
spaces provide continuous
sidewalks to access the
station. To the east of the
station along Jones Road,
the pedestrian bridge and
Iron Horse Trail provide a
Class I path to access the
station. Roadways near the
station due to receive new
bicycle facilities include Treat
Boulevard to the south and
Las Juntas Way to the north.
• Pittsburg/Bay Point Station
Pittsburg/Bay Point Station
is a major commuter station
located at the intersection of
Highway 4 and Bailey Road.
Pittsburg/Bay Point has a
large park and ride facility
and is accessible on foot via
Bailey Road and W Leland
Road in the City of Pittsburg.
Both streets have Class II
bike lanes and sidewalks.
The Delta de Anza Trail
comes very near the station
entrance. However, due to
the large parking lot, long
driveways, and proximity to
highway off-ramps, station
access on foot and by bike
can be challenging.

Mode Share
American Community Survey:
Means of Transportation to Work
The American Community
Survey (ACS) collects statistics
on Means of Transportation
to Work for every Census
geography level larger than a
block. This dataset estimates
the local share of home-
based work travel for workers
16 years and older by foot
and bike as well as other
modes. Because the ACS
only polls a representative
sample of residents in each
geography level per year (on

average, about 1% of the local

constrained by a margin of
error. This existing conditions
analysis only refers to the ACS
mode share metrics at the
unincorporated community
(“Census-designated place”, or
CDP) level, where sample sizes
are large enough and margins
of error small enough for
reasonably precise analysis. The
ACS Means of Transportation
to Work dataset is undoubtedly
useful for understanding home-
based work commute mode
share in residential areas,
but it is less appropriate for
estimating active mode share
for all trip types and beyond
residential areas. For example,
the ACS metrics will fail to
reflect recreational active travel
in rural areas, active travel
by students from homes to
schools, and work-related active
travel to residential areas by
domestic workers. See Table
2 for the active transportation
mode shares for home-based
work trips in CDPs countywide.
This information will contribute
to an assessment of active
transportation needs in each
unincorporated community.
47Contra Costa County Active Transportation Plan
California Household Survey:
Countywide Mode Split
The 2018 CBPP included
countywide analysis of travel
patterns by trip type and
length. Contra Costa residents
drive alone or carpool for
most of the trips they take;
of all trips, only 15% are made
by walking, biking or transit11
(see Table 3). For commute
trips only, most Contra Costa
residents drive alone, with
about 20 percent of residents
using non-auto transportation
(transit, walking, biking).
Contra Costans, however, are
more likely to walk for shorter
trips, less than one mile in
length, and are more likely to
bike for trips less than three
miles long (see Table 3). For the
majority of short trips, however,
residents still primarily drive,
along or in a carpool. Some of
these trips less than one-mile-
long have the potential to be
converted to walking or biking
trips, and those less than three-
miles-long could potential be
converted to bicycle trips.
The 2018 CBPP bicycle
backbone network along with
the recommendations included
in Chapter 6, will help to create
barrier connections (freeways,
waterways, etc.), improve
safety, reduce modal conflicts,
link to transit, and support
bicycling. By creating safe and
connected networks, additional
trips may be converted to those
of active transportation modes,
rather than drive-alone trips.

Strava Data
The County Public Works
Department has access
to Strava data through an
agreement with the Strava
Metro platform. Strava is an
app and Internet service used
for tracking bicycling, walking,
and running trips through GPS
data. The Metro tool aggregates
and anonymizes this data at
a countywide scale and can
provide a perspective on where
and how frequently users are
riding within a given region.
Historically, Strava data can
overrepresent recreational
trips, particularly bicycle trips
done by “Strong and Fearless”
style riders. However, it can still
provide a useful perspective on
where people choose to walk or
ride and increases or decreases
in trips over time.

Data is provided at a
countywide scale for the
entirety of Contra Costa
County, included incorporated
areas. Figures 12 and 13 show
the number of total trips and
individual users who used
Strava within the County for
each month from 2018 through
2021. The significant uptick
of trips taken in 2020 as
compared to prior years is likely
due to the impact of COVID-19,
with many residents seeking
ways to recreate and exercise
within their communities during
statewide travel restrictions.
VMT Reduction
Senate Bill 743 (SB 743)
changes how the impacts of
land use and transportation
projects and plans are
measured under the California
Environmental Quality
Act (CEQA). The state has
determined that vehicle miles
traveled (VMT) will be the
metric used to determine
these impacts. Projects and
plans that increase VMT will
have impacts under CEQA.
Active transportation can be an
alternative to decrease vehicle
travel to reduce or offset
increases in VMT, and thus
mitigate impacts.

Annual Collision
Trends
Annual collision trends show
a rise in collisions since 2014.
The total number of collisions
across all modes rose from
413 in 2014 to 486 in 2018.
Fatal and severe injury (KSI)
collisions dipped in 2016, but
show an upward trajectory.
Fatal collisions peaked in
2015 and 2018, with 17 and 19
fatalities, respectively.
Motor vehicle KSI collisions
experienced a dip in 2016
but have increased since
then. Bicycle-involved KSI
collisions decreased from
2015 to 2016, remained
constant between 2016 and
2017, and peaked in 2018
with eight KSI collisions.
Pedestrian-involved KSI
collisions saw a spike
between 2016 and 2017,
with KSI collisions jumping
from four in 2016 to ten in
2017. Pedestrian and bicycle-
involved collisions account
for 23% of all KSI collisions.

Collision Severity
Vulnerable road users,
including bicyclists and
pedestrians, are more
susceptible to fatal or severe
injury collisions. In terms of
collision mode, pedestrian-
involved collisions led to the
highest percentage of KSI
collisions at 30%, with 10% of
those collisions being fatal.
KSI collisions comprised 10%
of motor vehicle collisions
and 15% of bicycle-involved
collisions.

High-Injury Network
A high-injury network (HIN),
as mapped in Figure 25, was
created to highlight roadways
with a high concentration of
severe injuries and fatalities
across all modes within the
County. This HIN accounts
for 143 miles of roadway,
representing 22% of the 651
miles of roadways the County
maintains, and 12% of the 1,150
miles of non-freeway roads in
unincorporated Contra Costa
County. The number of non-
freeway collisions that occurred
in the study area between 2014
and 2018 was 2,174. The high-
injury network captures 70%, or
1,528, of these collisions: 252 of
the 2,174 non-freeway collisions
were either killed or severely
injured (KSI), and 73% of these
collisions, or 184, are captured
on the HIN.
Building on the HIN, a series
of collision systemic profiles
were developed to summarize
the notable trends across the
HIN and extrapolate to similar
locations within the County.
These profiles supported the
development of the County’s
Safety Action Plan. The bicycle
and pedestrian profiles are
further detailed in Appendix
C, and were also used to
develop the project list and
recommendations as part of
this ATP.

64 Contra Costa County Active Transportation Plan
Relationship to Other Plans &
Programs
This ATP builds on various existing Plans
and Programs. Key takeaways including
supporting goals, policies, and projects are
included below.
Contra Costa County General Plan
Contra Costa County’s current General Plan
was adopted in 2005 and includes goals,
policies, and implementation measures
to guide decisions on future growth,
development, and the conservation of
resources through 2020. The General Plan
is currently undergoing an update that will
provide an overview of the County’s plans
to address land use, transportation, housing,
climate change, environmental justice, and
other prominent issues over the next 20
years.
The 2020 General Plan’s Transportation and
Circulation Element includes the following
Fundamental Concept and specific goals
and policies related to active transportation.
When the County’s 2040 General Plan is
adopted, goals and policies from that plan
shall supersede those that follow.
Fundamental Concept
Streets should be designed, maintained according to the
“Complete Streets” philosophy, which accomplishes the
following:
• Specifies that ‘all users’ includes pedestrians,
bicyclists, transit vehicles and users, and motorists, of
all ages and abilities.
• Aims to create a comprehensive, integrated,
connected network.
• Recognizes the need for flexibility: that all streets are
different and user needs will be balanced.
• Is adoptable by all agencies to cover all roads.
• Applies to both new and retrofit projects, including
design, planning, maintenance, and operations, for the
entire right of way.
• Makes any exceptions specific and sets a clear
procedure that requires high-level approval of
exceptions.
• Directs the use of the latest and best design standards.
• Directs that complete streets solutions fit in with
context of the community.
• Establishes performance standards with measurable
outcomes.
65Contra Costa County Active Transportation Plan
Goals
5-A: To provide a safe, efficient, and integrated
multimodal transportation system.
5-G: To provide access to new development while
minimizing conflict between circulation facilities
and land uses.
5-I: To encourage use of transit.
5-J: To reduce single-occupant auto commuting
and encourage walking and bicycling.
5-K: To provide basic accessibility to all residents,
which includes access to emergency services,
public services and utilities, health care, food and
clothing, education and employment, mail and
package distribution, freight delivery, and a certain
amount of social and recreational activities.
5-L: To reduce greenhouse gas emissions from
transportation sources through provision of transit,
bicycle, and pedestrian facilities.
Policies
Circulation Phasing and Coordination
5-3: Transportation facilities serving new urban
development shall be linked to and compatible
with existing and planned roads, bicycle facilities,
pedestrian facilities and pathways of adjoining
areas, and such facilities shall use presently
available public and semi-public rights of way
where feasible.
66 Contra Costa County Active Transportation Plan
Circulation Safety, Convenience and Efficiency
5-11: The use of freeways for community circulation
shall be minimized by prioritizing transit circulation,
safe, direct non-motorized routes, and secondarily
by additional arterials and expressways.
5-13: The use of pedestrian and bicycle facilities
shall be encouraged. Proper facilities shall be
designed to accommodate bikes, pedestrians, and
transit.
5-14: Physical conflicts between pedestrians,
bicyclists, and vehicular traffic, bicyclists, and
pedestrians shall be minimized.
5-15: Adequate lighting shall be provided for
pedestrian, bicyclist, and vehicular, safety,
consistent with neighborhood desires.
5-16: Curbs and sidewalks shall be provided in
appropriate areas.
5-21: New development shall contribute funds and/
or institute programs to provide adequate bicycle
and pedestrian facilities where feasible.
5-22: New subdivisions should be designed to
permit convenient pedestrian access to bus transit
and efficient bus circulation patterns.
Alternative Transportation/Circulation Systems
5-23: All efforts to develop alternative
transportation systems to reduce peak period
traffic congestion shall be encouraged.
5-24: Use of alternative forms of transportation,
such as transit, bike, and pedestrian modes,
shall be encouraged in order to provide basic
accessibility to those without access to a personal
automobile and to help minimize automobile
congestion and air pollution.
5-25: Improvement of public transit shall be
encouraged to provide for increased use of local,
commuter and intercity public transportation.
5-30: Street systems shall be designed and/or
modified to discourage additional through traffic in
existing residential areas, but not at the expense of
efficient bus transit or bikeways.
67Contra Costa County Active Transportation Plan
Climate Action Plan
The County’s Board of
Supervisors adopted the
Climate Action Plan (CAP)
in December 2015. The CAP
is comprised of polices
and measures that, when
implemented, will enable the
County to meet its target
for greenhouse gas emission
reductions. The CAP includes
the following transportation
and land use strategies for
implementing the bicycling
and walking network as a
strategy to reduce greenhouse
gas emissions from what
would otherwise have been
trips in private automobiles.
The following, included in the
2015 CAP, relate directly to the
Active Transportation Plan.The
County is currently updating its
CAP, expected to be complete
in late 2022.
Goal: Reduce transportation emissions
Action Items
• Improve transit services to help alter long-term patterns of
automobile dependence
Goal: Reduce vehicle miles traveled
Action Items
• Collaborate with BART and other transit providers to increase
ridership in the County
• Prioritize alternative mode access to BART and other transit
stations
68 Contra Costa County Active Transportation Plan
Action Items
• Collaborate with local
transportation, land use
agencies, nonprofits, and
other stakeholders to expand
bicycle and pedestrian
facilities and existing public
transportation (BART,
Amtrak, AC Transit, County
Connection, and Tri Delta
Transit)
• Work with the Contra Costa
Transportation Authority,
local school districts, and
advocacy organizations
such as the East Bay Bicycle
Coalition to encourage
bicycle safety classes in all
schools
• Update County road
standards, as opportunities
arise, to accommodate all
modes of transportation
in local street designs
(i.e., complete streets).
Implement standards as part
of routine maintenance and
striping.
• Through periodic updates
to the Contra Costa
Transportation Authority’s
Countywide Bicycle and
Pedestrian Plan, identify
opportunities to improve
access to community-wide
bicycle and pedestrian
networks by closing gaps
in the network, removing
barriers, and providing
additional bike- and
pedestrian-oriented
infrastructure
Goal: Maintain and expand access to goods, services, and other destinations through increased
transportation alternatives (mobility improvements) and improved proximity (land use improvements).
• Establish a 2020 mode share
goal for bicycling by a Board
of Supervisors resolution,

Ordinance Code
The County’s Ordinance
Code includes ordinances
that address how
development should
occur within the County.
Multiple sections are
relevant to this plan, as
they provide guidance and
requirements on topics
such as the installation of
sidewalks, bicycle parking,
and the implementation
of transportation demand
management (TDM)
programs. Guidance on
TDM is intended to further
the transportation goals of
the County General Plan,

The purpose of this chapter is
to implement the provisions of
the general plan to promote a
more balanced transportation
system that takes advantage of
all modes of transportation by:
• Incorporating pedestrian,
bicycle, and transit access
into improvements proposed
in development applications;
• Incorporating the overall
intent and purpose of this
chapter into the land use
review and planning process;
• Allowing requests for
reductions in the off-street
parking requirements for
residential or nonresidential
projects that have a
conceptual TDM Program;
• Providing information to
residents on opportunities
for walking, bicycling,
ridesharing and transit.
MTC Regional Active
Transportation Plan
MTC’s Regional Active
Transportation Plan,
currently underway, will
help guide investments in
infrastructure and regional
policy development and
implementation supporting Plan
Bay Area 2050.
The key elements of the Active
Transportation Plan include:
• Development of a regional
active transportation
network, a Plan Bay Area
Blueprint strategy, that
builds off adopted state,
regional, county, and local
bicycle / pedestrian / trail
plans;
• Stakeholder engagement
through a Technical Advisory
Committee and community-
based organizations;
• Policy and program analysis,
updated with an equity and
Vision Zero focus, including
the review and update of
MTC’s Complete Streets
Policy (MTC Resolution
3765);
• Funding analysis to identify
the constraints and potential
future funding scenarios to
build-out a regional active
transportation network and
implement the Plan Bay Area
2050 strategies; and
• Creation of a prioritized
5-Year Implementation Plan,
in coordination with Plan Bay
Area 2050’s Implementation
Plan, that will include
actions to support active
transportation in response
to the COVID-19 pandemic’s
transportation-related needs.
71Contra Costa County Active Transportation Plan
Contra Costa County Safety
Action and Vision Zero Plans
In 2020, the County kick-started
a safety planning process for
unincorporated areas of Contra
Costa County, which began as
a Safety Action Plan (funded
as a Systemic Safety Analysis
Report, SSAR, from Caltrans)
and evolved into a Vision Zero
Action Plan. CCTA’s Vision Zero
Framework served as the base
for the CCC Vision Zero Plan’s
HIN, also used for this report. To
provide the latest information,
five years of the most recent
collision data were analyzed
to create a collision landscape
analysis, high-injury network
(HIN), and collision profiles,
which was then matched with
countermeasures to reduce
these types of collisions
on County roadways. This
analysis was presented to a
stakeholder advisory group to
solicit feedback and identify an
engineering-focused project
list for the County to use when
applying for grant funding.
Community feedback was also
collected as part of the Safety
Action Plan, where feedback
was gathered around safety
when walking, biking, and
driving in the County.
The Vision Zero Plan focused
on implementation strategies
that fall under the Vision Zero
Core Elements: Leadership and
Commitment, Safe Roadways
and Safe Speeds, and Data-
Driver Approach, Transparency,
and Accountability. Additional
safety countermeasures were
identified to include road
users and post-crash care,
supplementing the Safety
Action Plan’s engineering-
focused countermeasures on
roadway design and speed
reduction. The countermeasures
were organized under five
categories: safe road users,
safe speeds, post-crash care,
equity considerations, and
emerging technologies. The
Vision Zero Plan also included
a list of existing programs,
funding sources, and an action
plan for the County. The Action
Plan strategies to reduce KSI
collisions on County roadways
identified the party/parties
responsible for leading the
action and supporting agencies.
The Safety Action and Vision
Zero Plans identified locations
throughout the County
with high concentrations of
collisions, including a special
emphasis on bicycle- and
pedestrian-involved collisions.
The findings from these plans
allowed the ATP team to
identify key issues and risk
factors associated with these
locations and take a systemic
approach to identify other
locations throughout the
County with similar risk profiles.
72 Contra Costa County Active Transportation Plan
CCTA Bicycle and
Pedestrian Plan
CCTA’s Bicycle and Pedestrian
Plan, adopted in 2018, focused
on creating a plan to encourage
and support walking and
biking in Contra Costa County.
Elements of this Plan included
a County Baseline Report to
better understand the on-the-
ground conditions in each sub-
region along with webmaps
that allow local jurisdictions to
edit their bicycle and pedestrian
networks and coordinate
regionally significant facilities.
The Plan covers topics such as
low-stress bikeway networks,
connectivity to transit, bicycle
super highways, advanced
treatments for pedestrian and
bicycle design, and a level of
traffic stress (LTS) analysis
for the highest ranked priority
projects. The proposed bicycle
and pedestrian backbone
network and pedestrian priority
areas were used as a starting
point for many of the projects
outlined in this plan.
Caltrans District 4 Bicycle
and Pedestrian Plans
Caltrans District 4’s Active
Transportation Plan identifies
and prioritizes pedestrian
needs along and across the
State Highway System (SHS)
to guide future infrastructure
investments. The Plan includes
maps and charts that describe
the walking conditions and
connections to transit along the
SHS in District 4. A prioritized
list and map of location-based
pedestrian needs is provided,
accompanied by a toolkit and
implementation strategy to
address these needs with local
partners and the public. The
list of recommended projects
in the Plan will overlap with
active transportation projects
to be constructed through the
State Highway Operation and
Protection Program (SHOPP).
While the Caltrans plans focus
on state-owned facilities,
the District 4 Plan has some
overlap with projects in this
ATP, and close coordination and
collaboration will be needed
for successful implementation.
Examples include: additional
Class I trail improvements
at Bailey Rd and Highway 4,
reconstruction of the Hilltop
Drive/I-80 interchange to
improve bicycle and pedestrian
access, and a trail connection
along Highway 4 between
Concord and Bay Point.

COMMUNITY
INPUT AND
COLLABORATION
75Contra Costa County Active Transportation Plan
and advertising methods
are detailed in the following
sections. The ATP included
a two-phase engagement
process:
Phase 1
Phase 1 focused on listening to
the community and soliciting
feedback on existing conditions,
access to key destinations, and
community concerns about
accessibility and comfort for
people walking, biking, and
rolling. This phase of the project
lasted from March through
July 2021, to accomplish the
following goals:
• Develop a shared vision
and goals for active
transportation in Contra
Costa County
• Identify key corridors
and destinations, active
transportation infrastructure
gaps, and opportunities for
improvement
Engagement
Strategy
This section provides an
overview of the public outreach
process that was central
to the development of the
recommendations in this plan.
Hearing from a diverse and
representative group of County
residents and stakeholders
was vital for the development
of this Active Transportation
Plan (ATP). Using in-person
and virtual engagement
methods the project team
made reasonable efforts to
reach a diverse group of Contra
Costa County residents and
stakeholders while following
appropriate health and
safety protocols in relation
to the COVID-19 pandemic.
An example of this effort
includes installing temporary
decals throughout the County
that included a QR code to
the Plan’s website. Digital
engagement materials were
made available in English and
Spanish. Specific engagement
Phase 2
Phase 2 presented draft
infrastructure recommendations
to the community. Draft
recommended improvements
were presented to the
community for review and
comment. Phase 2 was
completed between the months
of September 2021 and January
2022. Phase 2 had the following
goals:
• Ensuring all stakeholders
were provided with
information about the draft
project recommendations
• Receiving feedback on
desired adjustments to draft
project recommendations
76 Contra Costa County Active Transportation Plan
Engagement Events
and Activities
A multi-pronged approach
of events and activities was
used to increase participation
from the community at large
with a focus on historically
underserved communities.
Phase 1 of community
engagement included two
virtual community workshops,
an interactive webmap on
the project website, an
online survey, and three
virtual stakeholder meetings.
Phase 2 included one virtual
community workshop, an
interactive webmap containing
project recommendations, five
community pop-up events, and
presentations at six targeted
community meetings.
Community Engagement
Themes
Throughout both phases of the
ATP’s community engagement
process, several key themes
emerged from County residents
and stakeholders:
• Need to improve safety,
especially for safe routes to
schools
• Need to improve access to
essential destinations like
parks, trails, and grocery
stores
• Desire to use trails as low-
stress connectors between
unincorporated areas and
cities
• Need to prioritize transit
access, especially walking
improvements (sidewalks
and crossings) around bus
stops
• Need to provide more
separated bikeways and
trails throughout the County
because they provide
the most separation from
vehicles
• Need to provide traffic
calming and more direct
walking and biking options
• Need to provide secure
bike parking at community
destinations across the
County
• Need to improve walking-
and bicycle-focused
wayfinding signs, especially
along trails
• Need to provide more
amenities (benches, water
fountains, lighting, etc.)
along trails
• Need to provide educational
programs and opportunities,
including driver education
• Desire from cities and other
jurisdictions to coordinate
with the County on
maintenance (capital and
scheduling)
• Need to address large or
asymmetrical intersections,
multilane roadways, and
high-speed traffic on local
and mountain roads, which
can be mental and physical
barriers for walking, biking,
and rolling.

Phase 1 Outreach
Community Workshops
Two virtual community workshops were hosted
during the month of May 2021. The workshops
were held virtually under strict COVID-19 health
and safety protocols. The project team promoted
the workshops using Contra Costa County Public
Works social media and through community
partners.
During the workshops, attendees shared their
thoughts on walking, bicycling, and rolling in
unincorporated Contra Costa County, places they
walk and roll to, and what their priorities and vision
for the future are. Workshop attendees highlighted
the need for better connections to destinations,
including the following:
• Parks, recreational centers, and community
centers
• Transit including BART and bus stops
• Schools
• Retail areas, including grocery stores
• The Bay Trail, the shoreline, and other open
space areas
Other high priorities for residents included the
need for traffic calming, especially on residential
streets and cross-county corridors (e.g., San Pablo
Dam Road), and the need for more separated and
off-street facilities for users of all ages and abilities.

Project Website and Interactive Webmap
A project website (www.activecontracosta.org)
and interactive webmap were created to provide a
central location where the community could review
the goals of the project, learn about upcoming
events, and provide input on specific issues found
throughout the County roadways. The interactive
webmap allowed users to drop points at specific
locations where they found safety and connectivity
concerns, as well as draw current or potential
routes that they would consider walking, biking, or
rolling. To provide additional context, the existing
bicycle and pedestrian networks were included
in the map showcasing the network throughout
unincorporated areas. The community provided 97
comments; fellow website users liked/disliked those
comments 170 times. The community provided
ten narrative comments via the “contact us” form.
Within unincorporated areas, comments focused on
the following key themes:
• Cross-county corridors like San Pablo Avenue,
San Pablo Dam Road, Alhambra Valley Road,
and Appian Way are, in some cases, the only
practical way to move between destinations.
However, these corridors prioritize cars and are
stressful for bicyclists and pedestrians
• The County should complete sidewalks and
improve intersection safety around schools
• Gaps in the Bay Trail should be closed, and with
better access provided to the Bay Trail, canal
trails, and other separated facilities

81Contra Costa County Active Transportation Plan
Stakeholder Meetings
The County facilitated three
virtual stakeholder meetings.
Each meeting included
stakeholders around three
thematic groups: community-
based organizations (CBOs),
schools, and partner agencies.
The following organizations
and agencies participated in
stakeholder meetings:
• City of San Ramon
• City of Orinda
• City of San Pablo
• City of Antioch
• City of Richmond
• City of Walnut Creek
• BART
• AC Transit
• CCTA
• John Swett Unified School
District
• District 1 Supervisor’s Office
• Bike East Bay
• WCCTAC
• 511 Contra Costa County
• Mobility Matters
Online Survey
The community survey was
available on the project website
from April through August 2021.
It requested information from
residents about their current
travel behavior, comfort levels
walking and biking, and allowed
the general public to provide
additional feedback about
general active transportation
issues in Contra Costa County.
The survey was completed by
226 community members.
A high percentage (76%) of
respondents indicated they
walk multiple times a week, and
54% said they bike numerous
times a week. Respondents
used public transit occasionally,
with only 14% regularly
riding public transit, but 69%
reported riding the bus or train
occasionally. 84% percent of
respondents said they walk
or bike for their health and
“enjoy walking/biking.” 75% of
respondents said they currently
walk or bike “for fun/exercise”
and to parks and stores.
Respondents also provided
information about their comfort
while walking, biking, or rolling
around Contra Costa County.
Currently, 71% of respondents
feel comfortable walking
around their community, and
43% feel comfortable biking
in their community. 53% of all
respondents felt that more/
better bike lanes, greater
separation from vehicles,
more sidewalks, and safer
ways to cross the street would
encourage them to walk, bike,
and roll more around their
communities.
82 Contra Costa County Active Transportation Plan
Takeaways from stakeholder
meetings included the
following:
• Need to improve access to
community destinations
like parks, schools, and
community centers (for all
ages and abilities)
• Need to build better first-last
mile connections to major
transit stops and stations
• Need to improve the existing
walking and bicycling
facilities to help increase the
number of active and shared
trips across the County
• Need for the County to
partner with community
organizations and other
County agencies to promote
and educate the community
about walking and biking
options
• Need to slow vehicle speeds
to make walking, rolling, and
bicycling more comfortable

Interactive Webmap
In October 2021, the interactive webmap was
updated to include the draft recommendations for
the pedestrian and bicycle networks. Users were
able to like, dislike, and leave comments on draft
proposed projects. The webmap also allowed users
to trace additional recommendations along roadways
in need of sidewalk and/or improved bicycle facilities
for the project team to consider. The Contra Costa
County Public Works Facebook and Instagram pages
as well as complementary social media ads were
used to promote the project website. The County ran
focused ads, in English and Spanish, on Facebook
and Instagram in unincorporated areas of the County
to increase participation and reach a larger share of
the community. The County also ran targeted ads
in disadvantaged communities and communities
with lower exposure to other engagement methods.
Ads were shown to over 32,000 people, resulting
in almost 800 website visits from ads alone.
Between September and December 2021, about
1,400 stakeholders visited the project website (over
2,100 visits over the project’s life). Users provided
over 150 likes/dislikes and 23 comments on project
recommendations. Users also added 35 different
roadway segments for the project team to consider
for additional project recommendations. The top three
community-liked projects included:
• Danville Boulevard Buffered Bike Lanes
• Stone Valley Road Buffered Bike Lanes
• San Pablo Dam Road Separated Bikeway

PROJECT
DEVELOPMENT
AND SUPPORT
PROGRAMS
93Contra Costa County Active Transportation Plan
This Chapter discusses the
planned bicycle and pedestrian
projects, as well as supporting
programs for unincorporated
Contra Costa County.
Project Development
The plan was developed to
implement the goals outlined in
Chapter 2; namely, to promote
mode shift by improving
the safety and comfort of
pedestrians and bicyclists,
increase connectivity and
close gaps in the network,
improve access to schools and
community facilities, enhance
equity for communities that are
disproportionately impacted
by collisions and have seen
less infrastructure investment,
and foster collaboration
between key stakeholders and
neighboring jurisdictions to
create regionally significant
projects. Projects included in
this plan were developed and
prioritized based on a variety of
factors including:
• Killed or Severely Injured
(KSI) collision history
• Location within a CCTA
Pedestrian Priority Area
or along the CCTA Bicycle
Backbone Network
• Recommendations from
previous regional efforts
identified in plans from
Contra Costa County, CCTA,
and Caltrans
• Feedback from key
stakeholders and the
community
• Proximity to key destinations
such as schools, affordable
housing, senior centers,
post offices, libraries, parks,
transit stops, etc.
• Location within impacted
communities as identified by
MTC’s Equity Priority Areas,
the Healthy Places Index,
CalEnviroScreen, ACS data,
the Community Air Risk
Evaluation Program, and the
California Department of
Education
• Ease of constructability of
project
Each of these factors were
identified by the project team,
key stakeholders, and the public
as criteria needing to be met
when identify a robust project
list, that includes 6 near-term
priority projects.
The planned bicycle and
pedestrian networks and
associated projects were shared
for public review during Phase
2 outreach activities (detailed
in Chapter 2) and subsequently
updated based on the
community feedback received.

Walk Audits
A series of walk audits were conducted to assess
bicycling and walking facilities within impacted
communities of unincorporated Contra Costa
County. The audits focused on identifying existing
issues and concerns and identifying potential
improvements. Each audit involved touring
roadways around at least one school, existing trail,
and/or community amenity, as well as locations
flagged as challenging for bicycling or walking by
community members and key stakeholders. Audits
were conducted by the project team, with support
from advocacy groups, community members, and
County staff from the Public Works, Public Health,
and Conservation and Development Departments.
• Bay Point: Riverview Middle School, Pacifica
Avenue, Port Chicago Highway, Delta de Anza
Trail, Bella Vista Avenue, and Hanlon Way
• North Richmond: Shields-Reid Community
Center, Verde Elementary School, Wildcat Creek
Trail, and Richmond Parkway
• Rodeo: Rodeo Hills Elementary School, Lefty
Gomez Recreation Center, Rodeo Creek Trail,
and the Bay Trail
Observations from the walk audits directly
informed the development of the project
recommendations.

Planned Bicycle and
Pedestrian Networks
Planned bicycle and pedestrian
facilities are shown in Figures
26-32. The build out of these
networks is a long-term vision
for active transportation facilities
within the unincorporated County.
The network includes accessibility
and sidewalk improvements for
pedestrians; bike lanes, bicycle
boulevards, and separated
bikeways for bicyclists; and
crossing improvements, shared-
use paths, and trails to benefit
both bicyclists and pedestrians.
The proposed networks are
designed to provide connection
within and between communities,
to key destinations, and to
serve as recreational assets. A
complete list of the projects that
constitute this plan can be found
in Appendix A.

104 Contra Costa County Active Transportation Plan
Overview of Improvements
Future walking and bicycling trips will depend
on a number of factors such as the availability of
well connected facilities, appropriate education
and promotion programs designed to encourage
walking and bicycling, and location, density,
and type of future land development. With
appropriate bicycling and walking facilities in place
and implementation of employer trip reduction
programs, the number of people walking or biking
to work, school, or to shop could increase above its
current rate.
CCTA’s 2018 Countywide Bicycle and Pedestrian
Plan12 provides guidance on corridor improvements
with context sensitive design in Appendix C, Best
Practices: Pedestrian and Bicycle Treatments
and acknowledges a need for trade-offs across
competing modal demands. A layered network
approach balances tradeoffs by prioritizing certain
modes on identified streets and providing continuity
for the chosen mode while accommodating other
modes or encouraging use on parallel streets. In
planning for a countywide plan such as this one, this
approach was taken for project recommendations
by providing select treatments for a prioritized
mode while ensuring increased safety for all modes.
Once recommendations are implemented, the
active transportation network will provide safer and
more direct travel paths throughout the County.
Improvements are in line with the following criteria:
• Connection to Activity Centers: Schools,
community facilities, the library, the community
center, parks, open space, and neighborhood
commercial districts should be accessible by
foot or bicycle. Residents should be able to walk
or bike from home to both local and regional
destinations.
• Comfort & Access: The system should provide
safe and equitable access from all areas of
the County to both commute and recreation
destinations and should be designed for people
of all levels of ability.
• Purpose: Each link in the system should serve
one or a combination of these purposes:
encourage bicycling for recreation, improve
facilities for commuting, and provide a
connection to the Countywide bike network. On
street facilities should be continuous and direct,
and off-street facilities should have a minimal
number of arterial crossings and uncontrolled
intersections.
• Connection to Regional Networks: The
system should provide access to regional
bikeways, regional trails, and routes in adjacent
communities.

105Contra Costa County Active Transportation Plan
Crossing and Intersection
Improvements
Several crossing improvements
are recommended, either as
standalone spot improvements
or as part of broader projects to
increase safety and comfort for
pedestrians, as well as bicyclists
at certain trail crossings. The
decision to install a marked
crosswalk at an uncontrolled
location should be based
on engineering judgement,
engineering study, or other
considerations as appropriate
for each individual case. Some
of these considerations may
include the following:
• Pedestrian travel demand,
typically 20 pedestrians per
hour or more
• Service of a facility or
use that generates higher
pedestrian travel or serves
a vulnerable population
(for example children,
elderly, or persons with
disabilities). This may
include schools, hospitals,
senior centers, recreation/
community centers, libraries,
parks, and trails. Service of
such facilities can justify
pedestrian improvements to
areas of less demand than
20 pedestrians per hour.
• Sight distance requirements,
using appropriate stopping
sight distance guidance
from AASHTO’s A Policy
on Geometric Design for
Highways and Streets or
Caltrans’ Highway Design
Manual
• Delay to pedestrian
movements
• Distance to nearest crossing
• Guidance of the California
Manual on Uniform Traffic
Control Devices (MUTCD)
Additional improvements
for crossings at uncontrolled
locations, such as the use of
high visibility markings, median
refuges, and curb extensions,
should be considered as
appropriate. Further design
guidance on the determination
of crossing treatments can
be found in Appendix C, Best
Practices: Pedestrian and
Bicycle Treatments of the 2018
CCTA Countywide Bicycle and
Pedestrian Plan and the FHWA
STEP Guide.13
Signalized intersections are
typically large with multiple
lanes of traffic in each direction,
especially where arterial and/
or collectors roadways meet.
At these locations, crosswalks
are typically marked, but
have long crossing distances.
In some cases, intersections
may have slip lanes, further
lengthening crossing distances
for pedestrians and bicyclists;
these lanes are not signalized,
allowing vehicles to make
these turns at higher speeds.
At all-way stop controlled
intersections, vehicles stop
and give the right-of-way
13 Federal Highway Administration.
Safe Transportation for Every
Pedestrian (STEP). https://safety.fhwa.
dot.gov/ped_bike/step/resources/
106 Contra Costa County Active Transportation Plan
to pedestrians and bicycle
crossing the street.
Some all-way stop controlled
intersections do not have
marked crosswalks. Vehicles
may encroach into the
intersection at these locations,
impeding the pedestrian travel
way and cause sight distance
issues for those crossing.
Recommendations to enhance
safety for pedestrians and
bicyclists at controlled
crossings include:
• Ensuring pedestrian walk
speeds of 3.5 feet/second
at signalized crossings
and walk speeds as low as
2.5 feet/second at select
locations, such as near
schools, parks, and senior
centers.
• Installing countdown signals
at signalized intersections
where missing
• Installing advanced stop bars
in advance of each crosswalk
• Enhance accessibility with
directional curb ramps
(two per corner) instead of
diagonal ramps and ensuring
that all are ADA compliant
• Marked crosswalks on all
legs of the intersection that
serve a key desire line
• Median refuge islands and
thumbnails, as width and
path of turn maneuvers allow
• Good and unobstructed
sightlines
• Slip lane removal, where
feasible, and mitigation for
pedestrian safety where
they remain with a raised
crosswalk or protected right-
turns
• Far-side bus stops, instead
of locations on the near-side
of the intersection or in front
of mid-block crossings
• Minimized cycle lengths at
signalized intersections
• Protected turn phasing
instead of permitted across
marked crosswalks
• Installing pedestrian and
traffic preemption
• Installing bike boxes at
signalized intersections,
cohesive with surrounding
bicycle facilities
107Contra Costa County Active Transportation Plan
Intersection Redesign
In some cases, full intersection
reconstruction is needed to
address safety and access
issues for people walking
and biking. Examples may
include skewed intersections,
intersections that need slip
lane removal, or locations that
are significantly overbuilt and
require re-purposing of space
for walking and biking. With
Complete Streets corridor
projects like road diets,
intersection re-design can also
support speed management
and access to intersecting
bicycle and pedestrian facilities.
Intersection design in these
cases can include:
• Roundabout The types
of conflicts that occur at
roundabouts are different
from those occurring at
conventional intersections;
namely, conflicts from
crossing and left-turn
movements are not present
in a roundabout. The
geometry of a roundabout
keeps the range of vehicle
speed narrow, which helps
reduce the severity of
crashes when they do occur.
Pedestrians only have to
cross one direction of traffic
at a time at roundabouts,
thus reducing their
potential for conflicts. When
considering roundabouts,
designers should assess
opportunities to include
bikeways and consider
pedestrian desire lines.
• Protected Intersections
Protected intersections
use corner islands, curb
extensions, and colored
paint to delineate bicycle
and pedestrian movements
across an intersection.
Slower driving speeds
and shorter crossing
distance increase safety for
pedestrians. This intersection
design separates bicycles
from pedestrians and should
be considered at signalized
intersections with separated
Class IV bikeways or Class I
paths.
Supportive
Infrastructure
and Programs
To ensure comfortable trips
for bicyclists and pedestrians,
supporting infrastructure is
needed at intersections and
along roadways to make the
trip safe and comfortable for
all users, wayfinding is needed
to help users reach and identify
destinations, and for bicyclists,
secure bicycle parking is
needed at destinations.
Wayfinding
Wayfinding signage can be
used on both bicycle and
pedestrian facilities to guide
users to connecting facilities and
destinations. Good wayfinding
signs can also encourage
bicyclists and pedestrians to
visit local businesses. These
signs provide the most value
when installed at trail junctions,
intersections of key bicycling
and walking routes, and at
navigation decision points.
Chapter 9B of the California
108 Contra Costa County Active Transportation Plan
MUTCD provides guidance on
sign design and installation.
A limited number of wayfinding
signage has been installed
in conjunction with regional
trails, such as the Bay Trail. The
County will be adopting an
updated signage program that
includes directional/wayfinding
signs. Working in conjunction
with the operators of regional
trails, the County will install
additional signage directing
users to businesses districts,
schools, and community
facilities. Including the distance
in miles to nearby destinations
on signs can encourage
additional walking and
bicycling to those destinations.
Because the County has many
boundaries with neighboring
cities, the wayfinding program
should ideally collaborate with
cities on design and format
of signage. This will improve
legibility and consistency
of the bike and pedestrian
network as a whole. This
collaboration should also
include regional entities like
CCTA, the East Bay Regional
Park District and Bay Trail.
Bicycle Parking
Having a secure location to
store your bike once you
reach your destination is an
important part of making
a bike trip feasible. Bicycle
parking is typically installed
by developers as part of
residential and commercial
projects. The County’s Municipal
Ordinance Code outlines long-
term and short-term bicycle
parking requirements for
residential, cultural/educational,
commercial, and industrial/
manufacturing land uses. The
Code does not currently outline
requirements for County-owned
facilities, such as hospitals,
clinics, parks, libraries, and
community centers. Bicycle
parking should be installed
as appropriate at all these
locations.
Near bicycle parking locations,
installing fix-it stations allows
bicyclists to quickly repair
their bicycle if needed. Repair
stations promote bicycle
commuting and provide cyclists
with amenities to make their
experience better and safer.
Street Amenities
Sidewalk amenities such as
benches, shade structures
(manmade or street trees),
parklets, public art, and other
landscaping feature make a
location more inviting and
comfortable. These amenities
allow pedestrians and bicyclists
to take breaks throughout
their journey, provide shade
throughout the trip, and create a
welcoming space.
Pilot Projects
When planning new pedestrian
and bicycle facilities, the County
could coordinate with community
advocates and nonprofits to
consider, if funds are available,
temporary infrastructure
improvements on a pilot basis.
These pilot projects, also known
as “living previews” or “tactical
urbanism,” can be built using
inexpensive materials, and may be
short-term or for specific events.
Pilot projects provide hands-on
experience new ways to use public
space. can help test concepts
and built support for active
transportation investments.
109Contra Costa County Active Transportation Plan
Maintenance
The County has an informal
maintenance policy in place
for bicycle and pedestrian
facilities, and often relies on
citizen reports for issues,
including through the County’s
Mobile Citizen app.14 While
this is acceptable for some
maintenance issues such as
pedestrian signals and other
facilities that need infrequent
maintenance, more formal
policies would provide
benefits for other issues.
Additionally, responsibility
for maintenance of sidewalks
fall on the owners of fronting
property, as opposed to the
County. Thus, implementation
of a formal maintenance policy
that addresses both incidental
and periodic maintenance of
frequently used facilities would
encourage good practices
and address other ongoing or
14 https://www.contracosta.ca.gov/7875/Mobile-Citizen
periodic maintenance issues.
Multiple public comments spoke
to concerns about debris, glass,
and overgrown vegetation
on County facilities, including
existing shared-use paths. This
can be particularly problematic
for wheelchair and mobility
device users, who may be unable
to use some facilities or be
forced to travel in the roadway
due to these obstructions.
Bicyclists may be required to
move into vehicle traffic or be
deterred from riding.
To address these concerns, the
County could add policies for
regular shoulder or bike lane
sweeping on corridors frequently
used by bicyclists or other
users, especially where there
are no sidewalks, and incidental
sweeping policies to address
debris that may accumulate.
Similarly, a regular program of
vegetation maintenance along
shared-use paths under the
County’s purview would reduce
these concerns.
The addition of new facilities
within the County, including
Class IV Separated Bikeways,
may necessitate investments in
street sweeping vehicles that
can navigate the smaller widths
of these bikeways. The County
could also consider entering into
a cooperative agreement with
other jurisdictions throughout
the county to share costs or the
usage of such vehicles.
110 Contra Costa County Active Transportation Plan
Speed Limit
Policies & Programs
Crossing and Intersection
Improvements
In October 2021, California
Assembly Bill (AB) 43 was
approved by the Governor. This
bill highlights methodology
to lower speed limits on
additional corridors. AB 43
features the following five
major components, focused
on providing local jurisdictions
more flexibility in setting speed
limits, especially regarding
vulnerable road users:
• Engineering & Traffic Survey
(E&TS) option to extend
how long an E&TS remains
valid to 14 years
• Post E&TS agency can elect
to retain current or the most
recent past speed limit.
• Speed Limit Reduction
reduction of additional
5 mph based on several
factors, including
designation of local “Safety
Corridors”
• Prima Facie Speed Limits
options for 15 or 20 mph in
certain zones
• Business Activity Districts
option for 25 mph in any
business or residence district
The County should look for
opportunities to reduce speed
limits with this methodology,
prioritizing locations on the
high-injury network and/or
those with high activity levels
and vulnerable communities.
Data-Driven Speed
Management
To identify and prioritize
locations that could benefit
from speed limit reductions
and/or design changes, a
holistic analysis of speed
differentials between prevailing
speed and target speed could
be instructive. Wejo Travel
Speed and Driving Events Data
allows users to understand
travel speeds of vehicles on
roadways. This data, combined
with the development of target
speeds based on context, is a
mapping exercise that could
be moved forward to assist
the county with prioritizing
locations for speed limit
modifications.
111Contra Costa County Active Transportation Plan
Non-Infrastructure
Programs
To build public support and
use of active transportation
infrastructure investments,
the County will support and
collaborate with partners
on outreach, engagement,
and education activities.
Public Works can use existing
programs as venues for project
outreach and to educate
community members about
new and planned facilities.
Non-infrastructure programs
also need ongoing support
and funding. Because many
infrastructure grant programs
also include opportunities for
non-infrastructure or supportive
program components, Public
Works will coordinate with
staff from existing programs to
identify opportunities for joint
funding.
Existing programs that present
opportunities for collaboration
include:
• Safe Routes to School
programs are led through
partnerships including Street
Smarts Diablo, 511 Contra
Costa, and Contra Costa
Health Services. Public
Works can coordinate with
Safe Routes to Schools
programs to identify and
refine plans for school safety
infrastructure projects.
• Bicycle Education programs
provided by Bike East Bay
are encouragement classes
for adults, youth, and
families. Programs may take
the form of on- or off-the-
bike safety trainings, bike
mechanics classes, theft
prevention workshops, social
rides, learn-to-ride classes,
and more. The County can
partner with Bike East Bay
to seek funding to provide
or support free classes in
tandem with infrastructure
plans and projects. Bike East
Bay also provides driver-
focused education classes
about operating safely
around people bicycling
and walking. Classes
may be targeted toward
transit, delivery, or other
professional drivers, or for
teen learners.
• The Concord Bike Kitchen is
a community bike shop and
youth education program
led by Bike Concord located
at Olympic High School in
Concord. Because Olympic
High serves students from
a large area including
unincorporated areas, it is an
excellent venue for outreach
and collaboration on funding
opportunities.
• Bay Area Bike Mobile is
a regional program that
provides mobile bicycle
repair for schools and
communities. Community
events where the Bike Mobile
is in attendance are good
venues for local outreach on
infrastructure projects.
112 Contra Costa County Active Transportation Plan
Other non-infrastructure
programs that Public Works will
take a lead role in include:
Walking and Bicycling Audits
Walking and bicycling audits
identify barriers for travel
between home and key
destinations. They generally
include a tour of a school
area or neighborhood where
participants identify issues
related to walking and biking,
followed by a debriefing and
brainstorming session to
rank concerns and identify
potential solutions. Audits
are typically completed by
planners, engineers, and
other staff with experience in
pedestrian and bicycle issues.
They often include input from
stakeholders like school faculty
and/ or administrators, district
or community program staff,
parents, and students. The
stakeholders systematically
document conditions that
impact people walking or
bicycling to and from school
or other destinations and note
specific locations on a map. The
County will routinely conduct
walk and bike audits when
planning infrastructure projects
in school zones, business
districts, and near other key
destinations.
Bay Area Bike to Work Day
(BTWD)
Bay Area BTWD, recently
renamed to “Bike to Wherever
Day” during the COVID-19
shelter in place orders, is a
celebration of bicycles as a fun
and healthy way to get to work.
The County will participate in
BTWD by hosting energizer
stations on various trails or at
BART Stations. The energizer
stations provide participants
with refreshments, giveaways,
and bicycle information during
the morning and evening
commutes. BTWD is part of
National Bike Month in May.

CHAPTER 6
114 Contra Costa County Active Transportation Plan
IMPLEMENTATION
115Contra Costa County Active Transportation Plan
Given the scope of projects
within this plan, implementation
will take many years to
complete. Implementation
of each project is dependent
upon the availability and
acquisition of funding.
Improvements associated with
work on adjacent roadways
or maintenance projects can
be undertaken in a relatively
easier and lower cost fashion
than if implemented separately.
In these cases, some lower
priority improvements may
be implemented before
higher-priority improvements,
depending on the location.
Projects requiring land
acquisition, utility relocation,
or substantial drainage
modifications may require extra
time to implement. Detailed
feasibility and design studies
based on local conditions
will also be necessary for
the implementation of many
projects.
Implementation of this plan is
expected to occur:
• through active
transportation projects and
grants pursued to implement
this plan
• in conjunction with
maintenance and
improvement projects, such
as slurry seals, pavement
reconstruction, roadway
widening, or sidewalk
rehabilitation projects
• in conjunction with adjacent
land development projects
Completion of projects in
this plan will be reported by
staff to the County Board of
Supervisors and on the County’s
website. The County will
periodically update this plan,
ideally on a five-year timeline,
to reflect evolving needs and
progress toward completion.
Costs and Funding
This plan includes a wide range
of projects with varying degrees
of cost. Project cost estimations
were developed to give a
general idea of the anticipated
cost for each proposed project.
The cost estimates were based
solely on construction costs and
do not include other typical soft
costs associated with projects.
These include but are not
limited to design, environmental,
and permitting costs, traffic
control, mobilization, SWPP
(Stormwater Pollution
Prevention), construction
management, and inspection.
Projects were divided into
categories based on similar
project descriptions. For
corridor projects, a detailed
cost estimate was prepared
for one “guiding” project in
each category. This analysis
yielded a low-end and high-
end total project cost and per
linear foot cost for the guide
projects. The guide project
low/high-end per linear foot
estimates were averaged and
then applied to the similar
116 Contra Costa County Active Transportation Plan
projects in their corresponding
categories. For intersection and
spot improvement projects,
estimations were calculated
from recent project cost data.
Each project was grouped
into one of four cost range
categories denoted by one-to-
four-dollar signs as shown in
Appendix A.
The categories are listed as
follows:
• “$” for projects costing less
than $500,000
• “$$” for projects between
$500,000 and $1,500,000
• “$$$” for projects between
$1,500,000 and $5,000,000
• “$$$$” for projects over
$5,000,000.
Multiple federal, state, regional,
county, and local organizations
provide funding for pedestrian
and bicycle projects and
programs. A summary of
funding sources is provided in
Appendix B, Funding Sources.Pedestrian using

117Contra Costa County Active Transportation Plan
Construction
Considerations
During a development’s
construction period,
construction zones may
encroach on sidewalks,
crosswalks, or bicycle lanes.
Both pedestrians and bicyclists
may find themselves having
to make detours that may feel
unsafe, difficult to navigate,
or both. This can be especially
dangerous for children, the
elderly, those with disabilities,
and others who rely on a well-
maintained and well-marked
path for safe mobility or for
bicyclists who may encounter
sudden pavement changes or
construction debris in their
path.
FHWA provided guidance on
pedestrian and bicycle safety in
work zones in a webinar hosted
by the Pedestrian and Bicycle
Information Center.15
Alternative access routes should
include the following:
• Route located on the same
side of street if feasible
• Smooth, continuous surface
– no abrupt changes in curb
or grade of roadway
• Maintain existing width of
sidewalk or bike lane
• Work zone communications
should be audible and/or
detectable
• Protect and separate
pedestrians and bicyclists
with devices that maintain
accessibility and protect
users from equipment
• Install temporary traffic
control devices with
wayfinding messaging, and
provide workers with high-
visibility apparel
• Provide a temporary bus
stop location if a project
impedes access
• Avoid or remove obstacles
on sidewalks, paths, and
bicycle lanes
Through a project’s review
process, County staff should
also review site plans and
traffic control plans to ensure
adequate access and safety
are maintained through the
duration of construction.

Potential Outcomes
Following implementation
of the planned networks
and supporting programs,
substantial improvements may
be achieved in the number of
active transportation users
within the County. Table 8
presents a comparison of
bicycle, walk, and transit trips
by commuters for counties with
similar populations, land use, or
geographic traits. By increasing
Priority Projects
Through the prioritization
process noted in Chapter
5, seven projects were
identified as near-term
priorities for further study and
implementation. Each group
of projects will contribute to
growing the backbone network
of facilities for low-stress
bicycling and walking, and/or
remedy important deficiencies
or needs in the network.
An overview of each project
group, including a discussion
on challenges and project
features, is provided in the
following pages. Although these
projects were identified as top
priority, it is important to note
that additional feasibility and
design studies may be needed
prior to implementation.
Further community input and
engagement is anticipated
as these projects come to be
developed.
the facilities available to users,
mode share may increase to
levels seen in other comparable
counties, which could easily
result in doubling the number
of commute trips made on
bicycle or by walking. Because
these numbers do not include
shopping, school, recreational,
or other non-work trips, the
actual number of trips may be
higher than these comparisons.

Project Background
North Richmond is a small neighborhood
with two key destinations for pedestrians
and bicyclists: Verde K-8 School, located at
the northern terminus of Giaramita Street,
and Shields-Reid Park and Community
Center, located at the southern end of the
neighborhood in the City of Richmond
and bounded by Chesley Avenue, Kelsey
Street, Cherry Street, and Alamo Avenue.
In particular, students walk and bicycle
each day from school to after school
programs, and to/from their homes in the
neighborhood.
The North Richmond Neighborhood Network
project focuses on providing traffic calming,
sidewalks, safer crossings, and bicycle access
for people walking and biking between
Verde K-8 School, Shields-Reid, and other
community destinations on Giaramita Street,
Market Avenue, Chesley Avenue.
$8,500,000
ESTIMATED COST
There is an additional $2,100,000 in estimated
project development costs for a total estimated
project cost of $10,600,000.
121Contra Costa County Active Transportation Plan
Project Features
• On Market Avenue, narrow overall curb to curb
width and widen sidewalk on one side to 10 feet
to provide a multi-use path.
• On Market Avenue, build curb extensions at all
intersections, and provide mini roundabouts or
neighborhood traffic circles at the intersections
at 1st Street and 2nd Street for speed reduction.
• On Giaramita Street and Chesley Avenue,
construct bicycle boulevards with traffic
calming and pedestrian access improvements.
The design will include neighborhood traffic
circles and/or speed humps, as well as curb
extensions to provide a gateway to the
neighborhood street.
• Build crosswalks across Chesley Avenue at
Giaramita Street
• Construct complete sidewalks, closing all gaps
in access on both sides of all three streets.
Key Challenges
• Children biking to Verde K-8 School lack a low-
stress bicycle facility.
• No bicycle facilities exist on Market Avenue or
Chesley Avenue, two key corridors for access in
and out of North Richmond.
• Existing crosswalks at uncontrolled locations
lack safety enhancements and do not
correspond with pedestrian desire lines
between Shields-Reid Community Center and
Verde Elementary.
• Long stretches of neighborhood streets without
traffic controls allow vehicles to pick up speed
and do not support a comfortable walking and
biking environment. Grove Avenue and Silver
Avenue lack stop controls in all directions.
• Many existing sidewalks are narrow and do not
provide a comfortable walking experience for
pedestrians.

Project Background
A key north-south corridor in Bay Point,
Port Chicago Highway connects Willow
Pass Road with Pacifica Avenue, providing
access to multiple schools, neighborhood
food shopping at Shore Acres Shopping
Center, and from the Delta de Anza Trail to
homes on either side of the corridor. With
five vehicle lanes, narrow bike lanes, long
stretches with no crosswalks, Port Chicago
Highway is an uncomfortable place to walk
and bike.
The Port Chicago Highway Complete Streets
project would study and implement a road
diet to reduce the roadway to one lane in
each direction, provide separated Class IV
bikeways or a shared use path to improve
bike connections to the Delta de Anza Trail,
and upgrade pedestrian crossings to improve
access between residential neighborhoods in
Bay Point.
$3,600,000
ESTIMATED COST
There is an additional $900,000 in estimated
project development costs for a total estimated
project cost of $4,500,000.
125Contra Costa County Active Transportation Plan
Project Features
• Study and implement five lane to three lane
road diet and construct Class IV separated bike
lanes or a Class I shared use path.
• Upgrade signalized intersections to include
ADA-compliant curb ramps and signals,
protected left turn phasing, leading pedestrian
intervals, and high-visibility crosswalks.
• Study the potential addition of a marked
crosswalk across the northern leg at Kevin Drive,
with high-visibility striping and enhancements
for visibility. Depending on ultimate speed limit
of the segment, a treatment such as an RRFB
may be considered.
• Reconstruct the intersection of Port Chicago
Highway, Willow Pass Road, and the Delta de
Anza Trail. Provide a high-visibility multi-use
trail crossing on the west leg, and provide
a pedestrian crosswalk at all legs of the
intersection. The southbound slip lane should
be closed, but if this is not feasible, a raised
crosswalk can be provided to slow down traffic,
although this may impact heavy truck traffic.
• Provide shade trees and landscaping to mitigate
summer heat.
Key Challenges
• Long stretches of roadway without traffic
control encourage speeding and limit
pedestrian crossing opportunities between
neighborhoods.
• Existing narrow bike lanes alongside high-
speed traffic are uncomfortable and present
safety concerns, especially for children and
less experienced bike riders. A high level of
exposure to vehicle traffic results in a harsh and
challenging environment for people walking and
biking to neighborhood destinations.
• Incomplete crosswalks and long crossing
distances at Willow Pass Road impede access to
and from the Delta de Anza Trail

Project Background
Willow Pass Road is the main east-west
arterial connection between Bay Point and
the City of Pittsburg. It is the main transit and
commercial corridor in Bay Point and home
to Anuta Park and Ambrose Community
Center and Garden. Willow Pass Road is also
a difficult place to walk and bike, despite a
high need for access. With five vehicle lanes,
people using the narrow bike lanes and
exposed sidewalks need to navigate long
distances between crossings and walk or bike
alongside fast-moving traffic. It is a high-injury
corridor for both pedestrians and bicyclists,
with a history of fatal and severe injury
collisions.
The Willow Pass Road Complete Streets
Corridor project will include a feasibility study
for a road diet, with the goal of reimagining
this multi-modal corridor as a place that is
safe and comfortable to walk, bike, take the
bus, and drive. With potential to reduce the
number of travel or turn lanes or narrow the
travel lanes, the project will take a holistic
approach to the corridor, aiming to upgrade
existing bike lanes to a low stress bicycle
facility, provide improved pedestrian crossings,
and create a comfortable environment for
access to transit. The project will also create
a connection to the future Class IV facility on
Bailey Road to the Bay Point BART Station.
$7,600,000
ESTIMATED CONSTRUCTION COST
There is an additional $1,900,000 in estimated
project development costs for a total estimated
project cost of $9,500,000.
129Contra Costa County Active Transportation Plan
Project Features
• Road diet feasibility study along the corridor
with the goal of constructing a Class IV
separated bikeway.
• Enhance existing uncontrolled marked
crosswalk locations, including Clearland Drive,
Solano Avenue, Madison Avenue, and Bella Vista
Avenue. These could include rapid rectangular
flashing beacons or pedestrian hybrid beacons
based on speed and yielding conditions.16 The
outcome of the road diet study will determine
the final crosswalk enhancements.
• Enhance signalized intersections. Stripe high-
visibility crosswalks at all legs of intersections
with pedestrian destinations. Signal updates
should include northbound and southbound
protected or split left turn phasing at Kevin
Drive, upgraded clearance intervals at all
signals, and leading pedestrian intervals at
Bailey Road and Kevin Drive. Pedestrian safety
countermeasures should be implemented along
with potential protected intersections with Class
IV bikeway design and construction.
16 Use the FHWA Guide for Improving Pedestrian Safety at
Uncontrolled Crossing Locations to determine final design.
Key Challenges
• Willow Pass Road is on the high-injury network
for bicycle and pedestrian collisions, with
hot spots at intersections and uncontrolled
crosswalk locations.
• Narrow bike lanes are stressful for bicycling and
are not appropriate for children or new bike
riders to access neighborhood destinations.
• Previous outreach efforts have indicated area
residents and businesses have concerns about
the potential loss of street parking.
• There are a high number of existing driveways
along the corridor.

Project Background
With a new segment of the Bay Trail now
open from Hercules to Lone Tree Point
in Rodeo, just a few gaps still impede a
seamless, low stress bike ride from the
Alameda County-Contra Costa County border
to the Carquinez Bridge and destinations
beyond in Sonoma and Napa Counties. One
such gap is a three-mile stretch of San Pablo
Avenue between Crockett and Rodeo, where
bicyclists climb past refineries and alongside
semi-trucks to access the continuation of the
Bay Trail.
In 2016, Contra Costa County conducted a
feasibility study and community outreach
to identify a preferred design alternative
for providing bicycle and pedestrian access
along this section of San Pablo Avenue.17
The result was a recommendation for a road
diet and installation of a two-way shared
use path along one side of the roadway.
This high priority project for funding and
implementation will improve safety and
connectivity on this critical connector.

use path on the west side, upgrading and
continuing the existing path.
• Design and construct a protected intersection
at Richmond Parkway, providing high visibility
crosswalks, direct connection to the Bay Trail
segment on Richmond Parkway, and signal
timing to facilitate bicycle and pedestrian
access.
• Upgrade all curb ramps for ADA accessibility
• Stripe high-visibility crosswalks and add
advance stop bars at all legs of signalized
intersections for more direct access to bus
stops and neighborhood destinations.
• In addition to providing shared-use path, close
Class II bike lane gaps for more confident
cyclists. Study a road diet for traffic calming
and upgrades to buffered or Class IV bike lanes
in addition to a complete shared-use path on
the west side.
• For speed management, study a road diet,

discourage speeding.
Key Challenges
• Class II bike lanes are discontinuous.
• Sidewalks are narrow and deteriorating, with
non-compliant ADA ramps.
• Long crossing distances and significant
conflicts with turning vehicles exist at signalized
crosswalks, presenting safety concerns.
• There is currently no wayfinding or direct,
low-stress connection to the existing shared-
use path on Richmond Parkway from
neighborhoods along San Pablo Avenue.

Regional Corridors
Because Contra Costa County’s
unincorporated areas have
unusual borders interspersed
with neighboring cities and
towns, close coordination with
partner agencies is critical
for the implementation and
maintenance of a continuous
bikeway and trail network.
Regional arterial and trail
corridors are critical for
connectivity across barriers and
for access to destinations.
The following set of projects
represents these key
connections. Some are existing
bike lane or trail corridors, while
others are new. All are part of
CCTA’s low-stress backbone
network and have significant
opportunity for cross-
jurisdictional collaboration.
Arterial Corridors
• San Pablo Avenue As the
key north-south arterial
corridor in West Contra
Costa, San Pablo Avenue
provides multi-modal
access from Alameda
County up to the Carquinez
Bridge in Crockett. Priority

Projects will close network
gaps with upgraded Class
IV bike lanes and a critical
safety project at Appian Way
and Valley View Road.
• Pacheco Boulevard As
a main route between
Martinez, Pacheco, and
Concord, Pacheco Boulevard
is an important connection
to destinations in Central
Contra Costa County.
Projects will study and aim
to close gaps with Class
IV separated bikeways
and provide pedestrian
safety and connectivity
improvements.
• Concord Avenue A top
priority project from the
County’s Vision Zero
program, Concord Avenue is
a key connection and there
is currently a significant gap
in bicycle and pedestrian
access between Downtown
Concord and major
destinations like Diablo
Valley College and the Sun
Valley Shopping Center.
The recommended project
will study a road diet in
collaboration with the City
of Concord and provide
crossing enhancements, a

Regional Park District)
and local trail crossing
enhancements. All Iron
Horse Trail crossings of local
streets should be considered
for raised crossings and
visibility enhancements will
all routine paving projects.
• Contra Costa Canal Trail In
a large horseshoe shape,
the Contra Costa Canal Trail
serves Central County and
intersects many local parks
and other trails, including the
Iron Horse Trail. The County
can support and coordinate
with the East Bay Regional
Park District on the long-
term plan to connect the
Contra Costa Canal Trail
with the Delta de Anza
Trail, connecting Concord
with Bay Point through the
Concord Naval Weapons
Station.
• Delta de Anza Trail An
east-west trail spanning
most of East Contra Costa,
the Delta de Anza Trail
forms the backbone of
the bicycle network for
Bay Point, Pittsburg, and
Antioch. Recommended
projects include trail crossing
enhancements at key
152 Contra Costa County Active Transportation Plan
locations like Bailey Road
and Willow Pass Road. The
County can support and
collaborate with the East
Bay Regional Park District in
extending the Delta de Anza
Trail to the west to connect
with the future extension of
the Iron Horse Trail along
Walnut Creek to Waterbird
Way.
• Bay Trail With over 350
miles already open, the
vision for the Bay Trail is
a complete 500-mile trail
corridor ringing the Bay.
Contra Costa County can
support the complete vision
with key trail connections
along Richmond Parkway
and San Pablo Avenue, and
by moving forward local
projects that provide access
to the Bay Trail.
Potential new trail corridors that
are associated with projects in
this plan include:
• Marsh Creek Trail Along
Marsh Creek Road in
eastern Contra Costa
County, a feasibility study
is currently underway to
evaluate options for a new
trail that roughly follows
the alignment of Marsh
Creek Road. The study area
stretches from Clayton city
limits at the western end, to
the Round Valley Regional
Preserve at the eastern end.
Due to topographical and
environmental constraints
within the area, along with
adjacent private property
limitations, it is anticipated
that the proposed alignment
would include a mix of on-
and off-street separated
facilities. Collaboration
with EBRPD, Save Mount
Diablo, and local property
owners will be required for
implementation.
• Great California Delta Trail
The California Delta
Protection Commission
is leading the planning
and development of the
Great California Delta Trail,
a continuous regional
recreation corridor extending
around the Delta, including
the shorelines of five Delta
counties, and linking trail
systems from Sacramento
to the San Francisco Bay.
In Contra Costa County,
the completed trail would
connect the existing
Lafayette-Moraga and Marsh
Creek Trails with the Bay Trail
at Carquinez Strait Regional
Shoreline. Projects along
Carquinez Scenic Drive in
Port Costa and in Bay Point
will support and connect to
the future Great California
Delta Trail. The County can
proactively engage with the
Delta Protection Commission
and the East Bay Regional
Park District to collaborate
on opportunities to move the
long-term plans forward.

FUNDING
SOURCES
This appendix provides an overview of funding sources available
for project implementation from federal, state, and local sources.
163Contra Costa County Active Transportation Plan
SB 1 Funding
California’s Senate Bill 1 (SB 1),
also known as the Road Repair
and Accountability Act of 2017,
is a landmark transportation
investment to rebuild California
by fixing neighborhood streets,
freeways, and bridges in
communities across California
and targeting funding toward
transit and congested trade
and commute corridor
improvements.
The largest portion of SB 1
funding goes to California’s
state-maintained transportation
infrastructure. With this
funding, Caltrans has a goal of
repairing or replacing 17,000
miles of pavement in 10 years,
spending $250 million annually
for congestion solutions, over
$700 million for better transit
commutes, and supporting
freight improvements. The other
portion of SB 1 funding will go to
local roads, transit agencies, and
expanding the state’s pedestrian
and cycle routes. SB 1 funds
various grant programs.
Local Partnership Program
(LPP)
The Local Partnership Program’s
purpose is to provide local
and regional transportation
agencies that have passed sales
tax measures, developer fees,
or other imposed transportation
fees, with a funding of
$200 million annually from
the Road Maintenance and
Rehabilitation Account to
fund aging infrastructure,
road conditions, active
transportation, and health
and safety benefits projects.
LPP funds are distributed
through a 50% statewide
competitive component and
a 50% formulaic component.
Both programs are eligible
to jurisdictions with voter
approved taxes, tolls, and
fees dedicated solely to
transportation and the
competitive program.
Local Streets and Roads
Program (LSRP)
California has dedicated
approximately $1.5 billion per
year appointed by the State
Controller (Controller) to cities
and counties for basic road
maintenance, rehabilitation, and
critical safety projects on the
local streets and roads system.
Cities and counties must
submit a proposed projects list
adopted at a regular meeting
by their board or council that is
then submitted to the California
Transportation Commission
(Commission). Once
reviewed and adopted by the
Commission, eligible cities and
counties receive funding from
the Controller and an Annual
Project Expenditure Report
is sent to the Commission to
be transparent with program
funding received and expended.
164 Contra Costa County Active Transportation Plan
Active Transportation Program
(ATP) Funding
The Active Transportation
Program (ATP) was created
by Senate Bill 99 to encourage
increased use of active modes
of transportation such as
walking and biking. The goals
of the ATP include, but are
not limited to, increasing
the proportion of trips
accomplished by walking
and biking, increasing the
safety and mobility of non-
motorized users, advancing
efforts of regional agencies
to achieve greenhouse gas
reduction goals, enhancing
public health, and providing a
broad spectrum of projects to
benefit many types of users,
including disadvantaged
communities. SB 1 directs $100
million annually to the ATP, with
more than 400 of the funded
projects being Safe Routes to
School projects and programs
that encourage a healthy and
active lifestyle throughout
students’ lives.
Caltrans Sustainable
Transportation Planning Grants
The Sustainable Transportation
Planning Grants include
two parts: Sustainable
Communities Grants and
Strategic Partnerships Grants.
The Sustainable Communities
Grants have $29.5 million
set aside to encourage local
and regional planning goals
and best practices cited in
the Regional Transportation
Plan Guidelines. The Strategic
Partnerships Grants set aside
$4.5 million to identify and
address statewide, interregional,
or regional transportation
deficiencies on the state
highway system in partnership
with Caltrans. These grants
were released for Fiscal Year
2020-21 and applications were
due October 17, 2019. Grant
award announcements were
made in June 2020. There is
the possibility of another grant
on the horizon, but Caltrans
has not released any new
information yet.
Safe Routes to School
(SRTS) Funding
Safe Routes to School (SRTS) is
a program promoting walking
and bicycling to school through
infrastructure improvements,
tools, safety education, and
incentives to encourage these
modes of travel. Nationally,
10% to 14% of car trips during
the morning rush hour are
for school travel. SRTS can
be implemented at the state,
community, or local school
district level. Competitive
federal funding is available
through the Fixing America’s
Surface Transportation Act
(FAST Act). Depending on the
existing infrastructure, SRTS
may require that education,
transportation, public safety,
and city planning agencies
coordinate their effort.
165Contra Costa County Active Transportation Plan
California Office of
Traffic Safety (OTS)
Grant Programs
OTS administers traffic safety
grants in the following areas:
alcohol impaired driving,
distracted driving, drug-
impaired driving, emergency
medical services, motorcycle
safety, occupant protection,
pedestrian and bicycle
safety, police traffic services,
public relations, advertising,
and roadway safety and
traffic records.
Transportation
Development Act
(TDA)
Article 3 TDA Article 3 is
perhaps the most readily
available source of local funding
for bicycle projects. TDA funds
are derived from a statewide
quarter-cent retail sales tax.
This tax is returned to the
county of origin and distributed
to the cities and county on
a population basis. Under
TDA Article 3, two percent of
each entity’s TDA allocation
is set aside for pedestrian and
bicycle projects; this generates
approximately $3 million in
the Bay Area annually. Eligible
projects include the design
and construction of walkways,
bicycle paths and bicycle
lanes, and safety education
programs. According to MTC
Resolution 875, these projects
must be included in an adopted
general plan or bicycle plan
and must have been reviewed
by County’s bicycle advisory
committee.
California Cap-and-
Trade Funding
The Global Warming Solutions
Act of 2006 (AB 32) directed
the California Air Resources
Board (ARB) to institute
programs to reduce greenhouse
gas (GHG) emissions. The
Cap-and-Trade Program, a
key element of the ARB’s plan
to reduce emissions, funds
several programs that support
the goals of AB 32. Several
of these programs relate to
transportation and mode
shift. The Affordable Housing
and Sustainable Communities
Program (AHSC), for one,
provides funding to support
active transportation and
complete streets initiatives,
among other project types.
166 Contra Costa County Active Transportation Plan
Transformative
Climate
Communities (TCC)
Program
The TCC Program funds
community-led development
and infrastructure projects
that strive to make major
advances in environmental,
health, and economic
benefits in California’s most
disadvantages communities.
Eligible improvements for
this funding source include
active transportation and
public transit projects, transit
ridership programs and passes
for low-income riders, and
encouraging education and
planning activities to promote
increased use of active modes
of transportation.
California State
Parks Recreational
Trails Program (RTP)
The Recreational Trails Program
(RTP) provides funds for
recreational trails and trails-
related projects, including Class
I Bicycle Paths. The program is
administered at the state level
by the California Department
of Parks and Recreation
(DPR) and the Caltrans Active
Transportation Program
(ATP). The County would be
responsible for obtaining a
match amount that is at least
12% of the total project cost.
Transportation for
Livable Communities
MTC created the Transportation
for Livable Communities
(TLC) program in 1998. MTC
uses this program to finance
pedestrian, bicycle and
streetscape improvements near
public transit in cities around
the Bay Area. The purpose of
TLC is to support community-
based transportation projects
that bring new vibrancy to
downtown areas, commercial
cores, neighborhoods and
transit corridors, making
them places where people
want to live, work and visit.
Pedestrian- and transit-friendly
developments are hallmarks of
the program. The TLC program
has been incorporated into the
One Bay Area Grant (OBAG)
program.

One Bay Area Grants
(OBAG)
Currently preparing for
January 2022 adoption of its
third funding round, OBAG
uses federal STBG and CMAQ
funds to maintain MTC’s
commitments to regional
transportation priorities while
also advancing the Bay Area’s
land-use and housing goals.
Cities and counties can use
these OBAG funds to invest
in bicycle and pedestrian
improvements, Safe Routes to
School projects, TLC projects
and planning for Priority
Development Areas among
other uses. MTC distributes
OBAG funds to county
Congestion Management
Agencies in each Bay Area
County. The CMAs are then
responsible for selecting
eligible projects within each
county.
Bay Trail Grants
The San Francisco Bay
Trail Project—a non-profit
organization administered by
the Association of Bay Area
Governments—provides grants
to plan, design, and construct
segments of the Bay Trail. The
amount, and even availability,
of Bay Trail grants vary from
year to year, depending on
whether the Bay Trail Project
has identified a source of funds
for the program. As of 2016,
the Bay Trail Project is not
currently offering grants, but
may in the future.
Transportation Fund
for Clean Air (TFCA)
TFCA is a grant program
administered by the Bay Area
Air Quality Management District
(BAAQMD) and funded through
a surcharge on motor vehicles
registered in the Bay Area.
The Air District offers funding
to public agencies for trip
reduction, bikeways and bicycle
parking, and clean air vehicle
projects. A subprogram of the
TFCA is the Bikeways, Roads,
Lanes and Paths program, which
offers funding for bicycle parking
and bikeway projects (Class I-IV).
Funding will be offered on a first-
come, first-served basis until the
funds are spent. Bicycle projects
may also be funded through the
TFCA’s County Program Manager
Fund. Under this subprogram,
40% of TFCA revenues collected
in each Bay Area county is
returned to that county’s
congestion management
agency (CMA) for allocation.
Applications are made directly
to the CMAs, but must also be
approved by the BAAQMD.
169Contra Costa County Active Transportation Plan
return to-source funds. Measure
J also requires local jurisdictions
comply with the County’s
Growth Management Program
(GMP), which is described
below, to be eligible for funding
through two of the measure’s
programs.
Measure J requires that local
jurisdictions comply with
CCTA’s Growth Management
Program (GMP) to be eligible
for funding through two of the
Measure’s programs. Among the
requirements of the GMP is that
each jurisdiction “incorporate
policies and standards into its
development approval process
that support transit, bicycle
and pedestrian access in new
developments.” The Authority
has been implementing the
GMP since the adoption
of Measure C in 1988. The
GMP requires jurisdictions
to work together to address
regional and countywide
transportation issues. CCTA
works with RTPCs to implement
a Regional Transportation
Mitigation Program, which
is built from the fees and
impact programs adopted
by individual RTPCs. CCTA
requires jurisdictions to adopt
standards for evaluating the
impacts of new development
on walking, bicycling and
transit and also develops and
maintains computer models
and develops methodologies
for analyzing the effects of land
use changes and transportation
improvements.
Measure J
In November 2004, Contra
Costa voters approved Measure
J, which extended Measure C
(approved 1988), the county’s
half-percent sales tax for
transportation, until 2034. The
most explicit source of funding
for pedestrian and bicycle
projects is through Measure
J’s Pedestrian, Bicycle and
Trail Facilities (PBTF) program,
which funds projects identified
in the CBPP. The Measure J
Transportation for Livable
Communities (TLC) program
also supports mixed-use,
walkable and transit-accessible
development and projects
that encourage walking and
bicycling as its primary goals.
The measure also encourages
jurisdictions to fund bicycle and
pedestrian facilities through
other Measure J programs
including their shares of the 18%
170 Contra Costa County Active Transportation Plan
VMT Mitigation Fees
Robust and safe active
transportation networks
are necessary to increase
walking and bicycling to
existing destinations and
new development. A VMT
impact fee is an option to
ensure new developments
are paying their fair share
for improvements needed to
create these networks. This fee
could be based on vehicle trip
generation, trip length, and the
share of new trips per land use
type. This fee could provide
a local source of funding and
contribute to the local match
required for various funding
sources. For some projects,
alternatives to reducing VMT
may be limited, and a fee
benefiting active transportation
projects may be a viable option
to offset VMT increases.

Bicycle-Involved Collisions Along Rural
Roadways Where Bicycle Facilities Do Not Exist
Recreational bicyclists commonly travel on rural roadways throughout the County, especially on
weekends, and many of these roadways do not provide dedicated bicycle facilities. This profile
highlights these rural roadways where 13 bicycle KSI collisions occurred, accounting for 45% of
all bicycle KSI collisions. Installing dedicated bicycle facilities is the primary focus of the profile,
which may include Class II bike lanes, or widened shoulders. Countermeasures to consider
include bike signage, shoulder maintenance, and a need to implement traffic calming and speed
reduction treatments along rural roadways.

On rural roads where no sidewalk or marked crosswalks are present, pedestrians must walk
along the roadway and cross when they see a gap in oncoming traffic. Four rural KSI collisions
fit this profile, which comprises all of the rural pedestrian KSI collisions in unincorporated
Contra Costa County. Three collisions occurred at night. Recommendations for this profile
include an evaluation to assess why pedestrians are walking along these roadways, where
they are going, and how to increase the visibility of pedestrians. Countermeasures to consider
include installing pedestrian paths (which may include shoulder widening along with installing
delineator posts, bollards, or landscaping for physical protection), installing enhanced
crosswalks, and pedestrian-scale lighting.

Introduction
•Contra Costa County’s first Active Transportation Plan will serve as a
roadmap to enhance active transportation safety and mode share for
the unincorporated areas in Contra Costa County.
•Active transportation is any self-propelled, human-powered travel,
such as walking and bicycling.
•By prioritizing active transportation, Contra Costa County hopes to
create a more sustainable and healthy community and reduce
greenhouse gas emissions.
•The Active Transportation Plan works alongside the recently adopted
Vision Zero Plan to better serve the needs of our communities
countywide.
2
Vision and Goals
•Vision Statement
Contra Costa County will have an equitable transportation system that
supports active transportation for users of all ages and abilities, allowing
all to travel conveniently, reliably, and free from harm.
•Goals
1.Prioritize active transportation investments based on factors such as
collision history or systemic risk, location in an impacted community,
location near key destinations, and funding opportunities.
2.Shift trip modes by Contra Costa County residents and visitors from motor
vehicles to active modes such as walking and biking to create a more
sustainable community and reduce greenhouse gas emissions.
3.Provide a vision for arterials and collectors within the unincorporated
County roadway network to assist County departments in planning for
private development, capital projects, and maintenance efforts.

RECOMMENDATION(S):
ACCEPT update on the Sacramento-San Joaquin Delta water policy issues and the activities of the Delta Counties Coalition and PROVIDE
direction to staff.
FISCAL IMPACT:
Administrative report with no specific fiscal impact.
BACKGROUND:
A healthy, vibrant Sacramento-San Joaquin Delta Estuary (Delta) is closely tied to the physical, societal and economic health of those who live,
work and recreate in the San Francisco Bay-Delta region and throughout much of the state. The eastern portion of Contra Costa County is
located within the Delta and the County’s entire northern border is bounded by waterfront that flows from the Delta to the Bay. Thus, Contra
Costa County lies at the heart of the Bay-Delta region and the future of this nationally significant resource substantially influences the future of
the County. Restoring the health of the Delta protects the Bay which is linked to the long term success of the County as a whole.
Contra Costa County is a part of the Delta Counties Coalition (DCC). The DCC is a consortium of five Delta Counties, including Contra Costa,
Sacramento, San Joaquin, Solano, and Yolo, that work collaboratively to give one voice to the Sacramento-San Joaquin River Delta System and
its four million area-wide residents. The DCC advocates to (1) protect and enhance Delta communities, and (2) improve water quality and the
Delta ecosystem, while also being practical about the responsibility to provide a more reliable water supply for the State.
The attached presentation will cover the priorities and advocacy of the DCC, provide an update on the tunnel project describing the Bethany
Alternative, and briefly review the current conditions of water quality and salinity in the Delta in light of the third year of drought.
Staff recommends the Board accept the update on the Delta and provide direction as appropriate.

Power Point Presentation
RECOMMENDATION(S):
1. FIND that the Board of Supervisors has reconsidered the circumstances of the Statewide state of emergency proclaimed by the Governor on
March 4, 2020, and the Countywide local emergency proclaimed by the Board of Supervisors on March 10, 2020.
2. FIND that the following circumstances exist: (a) the Statewide state of emergency and the Countywide local emergency continue to directly
impact the ability of the Board of Supervisors in all its capacities, its committees, and its advisory bodies to meet safely in person because the
highly transmissible Omicron and BA.2 variants of COVID 19 are present in the County, and while the local COVID 19 case rate is stable,
wastewater surveillance data reflecting the presence of COVID-19 and COVID-19 test positivity numbers are increasing; and (b) the County
Health Officer's recommendations for safely holding public meetings, which recommend virtual meetings and other measures to promote social
distancing, are still in effect.
3. AUTHORIZE the Board of Supervisors, in its capacity as the governing board of the County, the Contra Costa County Fire Protection
District, the Housing Authority of the County of Contra Costa, the Contra Costa County Flood Control and Water Conservation District, and the
Contra Costa County In-Home Supportive Services Public Authority, and its subcommittees, to continue teleconference meetings under
Government Code section 54953(e) for the next 30 days.
4. AUTHORIZE all advisory bodies, committees, and commissions established by the Board in all its capacities, including but not limited to

Subject:Continuing Teleconference Meetings (AB 361, Government Code § 54953(e))
RECOMMENDATION(S): (CONT'D)
6. DIRECT the County Administrator/Clerk of the Board and staff to the various Board advisory bodies to take all actions necessary to
implement the intent and purpose of this Board order, including conducting open and public meetings in accordance with Government Code
section 54953(e) and all other applicable provisions of the Brown Act.
7. DIRECT the County Administrator/Clerk of the Board to return to the Board acting in all its capacities, no later than 30 days after this
Board order is adopted, with an item to reconsider the state of emergency and whether to continue authorizing virtual meetings under the
provisions of Government Code section 54953(e) and to make required findings as to all bodies covered by this Board order.
FISCAL IMPACT:
This is an administrative action with no direct fiscal impact.
BACKGROUND:
On October 5, 2021, the Board adopted Resolution No. 2021/327, which authorized the Board, in all its capacities, and certain
subcommittees and advisory bodies, to conduct teleconferencing meetings under Government Code section 54953(e). This section of the
Brown Act, which was added by Assembly Bill 361, allows a local agency to use special teleconferencing rules during a State declared state
of emergency. When a legislative body uses the emergency teleconferencing provisions under Government code section 54953(e), the
following rules apply:
The agency must provide notice of the meeting and post an agenda as required by the Brown Act and Better
Government Ordinance, but the agenda does not need to list each teleconference location or be physically
posted at each teleconference location.
The agenda must state how members of the public can access the meeting and provide public comment.
The agenda must include an option for all persons to attend via a call-in or internet-based service option.
The body must conduct the meeting in a manner that protects the constitutional and statutory rights of the
public.
If there is a disruption in the public broadcast of the meeting, or of the public's ability to comment virtually
for reasons within the body's control, the legislative body must stop the meeting and take no further action
on agenda items until public access and/or ability to comment is restored.
Local agencies may not require public comments to be submitted in advance of the meeting and must allow
virtual comments to be submitted in real time.
The body must allow a reasonable amount of time per agenda item to permit members of the public to
comment, including time to register or otherwise be recognized for the purposes of comment.
If the body provides a timed period for all public comment on an item, it may not close that period before
the time has elapsed.
AB 361 sunsets on January 1, 2024.
Under Government Code section 54953(e), if the local agency wishes to continue using these special teleconferencing rules after adopting
an initial resolution, the legislative body must reconsider the circumstances of the state of emergency every 30 days and make certain
findings. The agency must find that the state declared emergency continues to exist and either that it continues to directly impact the ability
of officials and members of the public to meet safely in person, or that state or local officials continue to impose or recommend measures to
promote social distancing.
The Board last considered these matters on March 29, 2022, made the required findings and authorized continued use of special
teleconferencing rules. The Board can again find that the Statewide state of emergency continues to exist, that the state and Countywide
local emergencies continue to directly impact the ability of the Board of Supervisors in all its capacities, and its subcommittees, and
advisory bodies to meet safely in person, and that state or local officials continue to impose or recommend measures to promote social
distancing.
The Public Health Officer has advised that the highly transmissible Omicron and BA.2 variants of COVID 19 are present in the County, and
wastewater surveillance data reflecting the presence of COVID-19 and COVID-19 test positivity numbers are increasing. In addition, on
April 15, 2022, the County Health Officer again issued recommendations for safely holding public meetings that included recommended
measures to promote social distancing. (See Attachment A, Health Officer’s Recommendations). Among the Health Officer's
recommendations: (1) on-line meetings (teleconferencing meetings) are encouraged as those meetings present the lowest risk of
transmission of SARS-CoV-2, the virus that causes COVID-19; (2) if a local agency determines to hold in-person meetings, offering the
public the opportunity to attend via a call-in option or an internet-based service option is recommended when possible to give those at
higher risk of and/or higher concern about COVID-19 an alternative to participating in person; (3) a written safety protocol should be
developed and followed, and it is recommended that the protocol require social distancing - i.e., six feet of separation between attendees; (4)
seating arrangements should allow for staff and members of the public to easily maintain at least six-foot distance from one another at all
practicable times.
CONSEQUENCE OF NEGATIVE ACTION:
The Board, in all its capacities, and its subcommittees and advisory bodies, would no longer conduct teleconferencing meetings under
Government Code section 54953(e).

Attachment A, Health Officer's Recommendations
Recommendations for safely holding public meetings
Each local government agency is authorized to determine whether to hold public meetings in person,
on-line (teleconferencing only), or via a combination of methods. The following are recommendations
from the Contra Costa County Health Officer to minimize the risk of COVID 19 transmission during a
public meeting.
1. Online meetings (i.e. teleconferencing meetings) are encouraged, where practical, as these
meetings present the lowest risk of transmission of SARS CoV-2, the virus that causes COVID 19. This is
particularly important when community prevalence rates are high. Our current trends as of April 15,
2022 in Covid-19 case rate and Covid-19 hospitalizations have plateaued at this time, but wastewater
surveillance data and COVID-19 test positivity has been increasing. In addition to this, the predominant
variant of Covid-19 being identified continues to be the Omicron variant, the impact of which on the
spread of Covid-19 has shown to dramatically increase COVID-19 transmission.
2. If a local agency determines to hold in-person meetings, offering the public the opportunity to
attend via a call-in option or an internet-based service option is recommended, when possible, to give
those at higher risk of and/or higher concern about COVID-19 an alternative to participating in person.
3. A written safety protocol should be developed and followed. It is recommended that the
protocol require social distancing, where feasible – i.e. six feet of separation between attendees; and
consider requiring or strongly encouraging face masking of all attendees and encouraging attendees to
be up-to-date on their COVID-19 vaccine.
4. Seating arrangements should allow for staff and members of the public to easily maintain at
least six-foot distance from one another at all practicable times.
5. Consider holding public meetings outdoors. Increasing scientific consensus is that outdoor
airflow reduces the risk of COVID-19 transmission compared to indoor spaces. Hosting events outdoors
also may make it easier to space staff and members of the public at least 6 feet apart.
6. Current evidence is unclear as to the added benefit of temperature checks in addition to
symptom checks. We encourage focus on symptom checks as they may screen out individuals with other
Covid-19 symptoms besides fever and help reinforce the message to not go out in public if you are not
feeling well.
7. Consider a voluntary attendance sheet with names and contact information to assist in contact
tracing of any cases linked to a public meeting.

Deputy Health Officer, Contra Costa County
RECOMMENDATION(S):
APPROVE and AUTHORIZE the Purchasing Agent, or designee, to execute on behalf of the Public Works Director, a blanket purchase order
with Syar Industries, Inc., in an amount not to exceed $1,250,000, for asphalt concrete of various types for road maintenance work, for the
period April 26, 2022 through April 25, 2025, Countywide.
FISCAL IMPACT:
The cost of purchasing asphalt concrete is funded 100% by Local Road Funds.
BACKGROUND:
On January 21, 2022, the County issued Invitation for Bid (IFB) 2201-553 for four asphalt concrete vendors, one each located in north, south,
east, and west County to ensure close proximity to the various job sites to maintain asphalt temperature and manage transportation costs. When
IFB 2201-553 closed on February 11, 2022, only one bidder had responded. On March 2, 2022, the County issued a second IFB, BID 2202-542,
and when it closed, no one had bid.
Having no bids to evaluate, and in an effort to establish unit costs, the Public Works Maintenance Division requested direct quotes from
historical vendors who had previously complied with the specifications in the bid documents. Only one vendor responded, with high unit costs
caused by the recent volatility in oil markets.

RECOMMENDATION(S):
APPROVE and AUTHORIZE the Director of Airports, or designee, to execute an amendment to the Consulting Services Agreement between
the County and the KPA Group dated March 12, 2019, for the Buchanan Field terminal project, to increase the payment limit by $10,200, from
$1,054,209 to a new limit of $1,064,409.
FISCAL IMPACT:
The increase in the contract amount will be paid by the Airport Enterprise Fund.
BACKGROUND:
During the construction of the Buchanan Field Airport Rescue Fire Fighting (ARFF) Terminal Building, the KPA Group is performing
architectural and construction administration support services. Those services include preparing architect’s supplemental instructions and
providing quality control. To provide the required quality control, the KPA Group must perform additional geotechnical services. The cost of
these additional services necessitates an increase in the contract limit by $10,200, from $1,054,209 to a new limit of $1,064,409. No other
changes are being made to the original contract.
CONSEQUENCE OF NEGATIVE ACTION:
If the increase in the payment limit is not approved, the KPA Group will not be able to perform the necessary additional geotechnical services.

Costa
County
Subject:Approve the Fifth Amendment to the Marsh Creek Recreational Trail License Agreement, Brentwood area.
BACKGROUND: (CONT'D)
In 2021, the District began its Three Creeks Parkway Restoration Project (“Project”). As part of the Project, a portion of the Trail operated
by EBRPD was removed from District-owned property. A parallel trail segment now exists on property owned by the City of Brentwood.
The Fifth Amendment to the License Agreement will remove the portion of the Trail no longer located on District-owned property, include
new trail segments, and authorize EBRPD to install interpretive signs. The remaining obligations under the License Agreement, as
previously amended, remain unchanged.
District staff recommend approving the Fifth Amendment to the License Agreement to ensure the License Agreement accurately describes
the Trail located on District property, and allows uses benefitting members of the public who will use the Trail.
CONSEQUENCE OF NEGATIVE ACTION:
EBRPD will not have the necessary rights over the new Trail segments and interpretive signs located on District property, and the License
Agreement’s description of the Trail will be incorrect.

opportunity to renew our commitment to crime victims by strengthening our partnerships and creating new ones, upholding the constitutional
mandates of Marsy's Law and mobilizing organizations and their leaders to continue the commitment to crime victims and the safety of our
community.
This year’s theme is “Enforcing victims’ rights. Expanding access to services. Ensuring equity and inclusion for all.” Victims’ Rights Week
recognizes prosecutors, support staff, law enforcement, crime victims and community members who have overcome so much to make our
community safer.

In the matter of:Resolution No. 2022/145
Proclaiming April 2022 as Child Abuse Prevention Month
WHEREAS, as a community, we have a responsibility to nurture and protect our children and help ensure
they become healthy and productive adults; and
WHEREAS, child abuse and neglect affect children of all ages, races, and income, and is 100 percent
preventable; and
WHEREAS, in Contra Costa County, the Child Abuse Prevention Council (CAPC) and Child Protective
Services (CPS), a program of Children & Family Services within the Employment and Human Services
Department, collaborate to continue protecting children through preventive services, response, intervention,
and investigation; and
WHEREAS, despite outreach and community efforts, the rising number of reported child abuse cases
remains a great concern and highlights the need for individuals and communities to work together to
increase protection and improve services for children who are abused or neglected; and
WHEREAS, more than 4 million cases of child abuse per year are reported across the country, and two of
the major risk factors leading to child abuse and neglect are family isolation and stress; and
WHEREAS, experiencing physical abuse or witnessing violence early in life can become a cycle, passed
down through generations, and children exposed to violence may consider it acceptable. Therefore, the
cycle of violence continues and can lead to other violent or dangerous actions; and
WHEREAS, children who have experienced abuse are nine times more likely to become involved in criminal
activities; and
WHEREAS, we cannot put a dollar value on the life of a child; however, we can work together to help end
the tragedy of child abuse by supporting children and families. The benefits of implementing prevention
programs greatly outweigh the substantial economic costs of maltreatment; and
WHEREAS, in 2020, the cumulative financial impact to Contra Costa County for the 720 verified survivors
of maltreatment is $338,000,000.
WHEREAS, these costs accrue over the course of survivors’ lives, yet the community will continue to incur
the same cost each year until we are able to reduce and ultimately end child abuse; and
WHEREAS, most experts believe the number of incidents of abuse are far greater than what is reported, and
early intervention is critical for preventing abuse and can positively impact at-risk families, protecting
children; and
WHEREAS, in Contra Costa County there are numerous committed agencies, parents, relatives, community
volunteers, public policymakers, and professionals who collaborate to eliminate child abuse and give our
children hope, security, and safety; and
WHEREAS, CAPC is a child abuse prevention service provider to Contra Costa County and urges
community members to report suspected child abuse to law enforcement, child welfare agencies or other
community hotlines;
NOW, THEREFORE, BE IT RESOLVED that the Contra Costa County Board of Supervisors joins in proclaiming April 2022
to be Child Abuse Prevention Month; recognizes the efforts of the Child Abuse Prevention Council and Children & Family
Services of the Employment and Human Services Department; and acknowledges both agencies for their dedication to preventing
child abuse in Contra Costa County.

April is Alcohol Awareness Month
WHEREAS, according to the Centers for Disease Control and Prevention, excessive drinking is responsible
for more than 4,300 deaths among underage youth each year, and cost the U.S. $24 billion in 2010: and
WHEREAS Alcohol Awareness Month provides an opportunity to increase outreach and education
regarding the dangers of alcoholism and issues related to alcohol; and
WHEREAS, to protect the health and safety of California residents a shelter in place order was issued at the
onset of the COVID-19 pandemic. Individuals and families experienced isolation and increased stress,
along with fear and anxiety. Concurrently, many States including California relaxed alcohol related laws to
provide economic support to bars and restaurants leading to a substantial increase of alcohol sales purchased
off premises, consequently increasing in the use of alcohol and other drugs; and
WHEREAS the National Survey on Drug Use and Health (NSDUH) of the Substance Abuse and Mental
Health Administration (SAMHSA) reported that by the end of 2020, 25.9 million past year users of alcohol
and 10.9 million past year users of drugs other than alcohol perceived that they were using these substances
“a little more or much more” than they did before the COVID-19 pandemic began; and,
WHEREAS people aged 12 to 20 years drink 11% of all alcohol consumed in the United States and more
than 90% of this alcohol is consumed in the form of binge drinking; and
WHEREAS research indicates that alcohol use during the teenage years could interfere with normal
adolescent brain development and increase the risk of developing Alcohol Use Disorder; and
WHEREAS youth who drink alcohol are more likely to experience changes in brain development that may
have life-long effects including, physical and sexual violence, school and social problems, increased risk of
suicide and homicide, and alcohol related vehicle crashes; and
WHEREAS research shows that parents are the number one reason why youth choose not to drink, and a
supportive family environment is associated with lower rates of alcohol use among adolescents; and
WHEREAS statewide prevention, treatment, and recovery efforts surrounding alcohol and substance use
can help individuals, families, and children coping with alcoholism and alcohol-related problems.
NOW, THEREFORE BE IT RESOLVED, that the Board of Supervisors declares April 2022 as Alcohol Awareness Month in
Contra Costa County. BE IT FURTHER RESOLVED that the Board of Supervisors call upon all citizens, parents, youth,
governmental agencies, public and private institutions, businesses and workplaces, hospitals, and schools in the County to
support efforts that will provide Hope, Help, and Healing for those families in our communities who are facing challenges with
alcohol use and abuse. PASSED AND ADOPTED by the Board of Supervisors of the County of Contra Costa, State of
California, at a regular meeting of the Board held on May 3, 2022.

RECOMMENDATION(S):
ADOPT Ordinance No. 2022-16, to increase fines and administrative penalty amounts for violations of the County Ordinance Code.
FISCAL IMPACT:
None. The costs of preparing this Ordinance were covered by the Land Development Fund.
BACKGROUND:
The County Ordinance Code includes several enforcement mechanisms to deter violations of the Code, including fines and administrative
penalties. Fines and administrative penalty amounts that may be imposed for a violation of a County ordinance are limited by State law. Recent
State legislation increased the authorized monetary penalties for violations of County ordinances, specifically for violations of building and
safety codes, short-term rental ordinances, and event permit requirements. The proposed ordinance would update the County Ordinance Code to
conform with the statutory limitations for fines and administrative penalties.
The County Ordinance Code includes the County’s Temporary Events Ordinance (Chapter 82-44, regulating events conducted on private
property) and Short-term Rental Ordinance (Chapter 88-32, authorizing the operation of a short-term rental with a permit and establishing
operational standards). County staff's experience is that most operators and property owners adhere to the permitting requirements and
operational standards of these ordinances. Additionally, the County's code enforcement approach for zoning and building code violations
emphasizes achieving compliance through notification and education. However, County staff has also encountered clearly intentional violations
of these ordinances that pose significant community safety risks. Examples include the increasing occurrence of large, unpermitted pop-up
events in rural areas that pose significant noise and safety impacts, and unpermitted short-term rentals used for parties. Operators that are
knowingly violating these ordinances are often commercially benefiting from the violations. Thus, monetary penalties must be significant to
deter violations or risk being viewed as the cost of doing business for these operators.

Subject:Increasing Fines for Violations of the Building and Safety Codes and Temporary Events and Short-Term Rental Ordinances
BACKGROUND: (CONT'D)
The proposed ordinance would also increase the fines and administrative penalty amounts for violations of building and safety codes,
including violations of Title 7 (Building Code) and Title 8 (Zoning) where the violation is associated with an unlawful building or structure.
The County has generally set fine amounts for violations of these types to be the maximum allowed under State law, due to the safety risk
these violations pose. The proposed increases would conform with the updated statutory limitations for fines and administrative penalties
imposed for violations of building and safety codes.
The proposed fine and administrative penalty amounts are listed below:
Revised Fine and Administrative Penalty Amounts
General Code Violations
$100 for a first violation (unchanged)1.
$200 for a second violation of the same ordinance within one year (unchanged)2.
$500 for each additional violation of the same ordinance within one year (unchanged)3.
Violations of Building and Safety Codes
$130 for a first violation ($100 currently)1.
$700 for a second violation within one year ($500 currently)2.
$1,300 for each additional violation of the same ordinance within one year ($1,000 currently)3.
$2,500 for each additional violation of the same ordinance within two years for certain violations related to
commercial properties (NEW)
4.
Violation of Event Permit Requirements (NEW)
$150 for a first violation of an event permit requirement1.
$700 for a second occurrence of the same violation of an event permit requirement by the same owner or
operator within three years of the first violation
2.
$2,500 for each additional occurrence of the same violation of an event permit requirement by the same
owner or operator within three years of the first violation
3.
Violation of the County’s Short-term Rental Ordinance (Ordinance Code Chapter 88-32) (NEW)
$100 for a first violation for failure to register or pay a business license fee1.
$1,500 for a first violation of Chapter 88-32, except for failure to register or pay a business license fee2.
$3,000 for a second violation of Chapter 88-32 within one year of the first violation3.
$5,000 for each additional violation of Chapter 88-32 within one year of the first violation4.
In accordance with State law, the proposed ordinance also provides a responsible party the opportunity to file a request for a hardship waiver
for certain increased penalties imposed for multiple violations. The responsible party must show that he or she has made a bona fide effort
to comply after the first violation and that payment of the full amount of the fine would impose an undue financial burden on their part. The
request for a hardship waiver must be accompanied by an affidavit and support documents or materials demonstrating that payment of the
full amount of the fine would impose an undue financial burden on the party.
CONSEQUENCE OF NEGATIVE ACTION:
If the Board does not adopt Ordinance No. 2022-16, County Code Enforcement staff will have less effective tools to require Code
compliance by property owners and operators that do not conform to regulations aimed at protecting the public health, safety, and general
welfare of county residents.

Subject:AB 2295 (Bloom) Local educational agencies: housing development projects - Oppose Unless Amended
BACKGROUND: (CONT'D)
House Location:Assembly
Last Amended Date:3/29/2022
Committee Location:Assembly Housing and Community Development
Committee Hearing Date:4/20/2022
The bill provides that a housing development project must be deemed an authorized use on any real property owned by a local
educational agency (LEA) if it meets specified affordability criteria and planning standards. (From the 4/1/2022 bill analysis)
LEA's currently have well known exemptions from local regulations for constructing educational facilities. The subject bill would
effectively extend those exemptions to cover the construction of housing (with restricted occupancy and income criteria as defined
in the bill). This would allow school districts, the County Office of Education, or charter schools to develop property as housing
outside the County's voter approved (Measure L-2006) urban limit line (ULL), "...even if that is inconsistent with any provision of a
city’s or county’s general plan, specific plan, zoning ordinance, or regulation." (From the 4/1/2022 bill analysis)
This is in conflict with the Board's adopted legislative platform which includes, "MAINTAIN local agency land use authority." and
a central component of the County's growth management strategy which is the Urban Limit Line (originally passed in 1990 and
reaffirmed in 2006). In addition to the conflicts with local regulation, the bill is in conflict with the State's greenhouse gas reduction
legislation (AB 32 [2006], SB 375 [2008], SB 743 [2013], et al), which have a goal of more compact development to reduce
vehicle miles traveled and land consumption.
While the limitations on extending services to any parcels outside the ULL will ultimately be a significant constraining factor, staff
believes that asserting local land use authority through the ULL is preferable to relying on these other constraints that are outside of
the County's direct control.
The following is an inventory of school district owned land outside the ULL:
Parcel #Owner ACREAGE

018310014 LIBERTY UNION HIGH SCHOOL DIST 18.57
011210028 LIBERTY UNION SCHOOL DIST 14.1
In considering this potential expansion of land use authority for school districts it is useful to consider the related issue of
incorporating land use planning principles and interagency coordination into school siting.
In 2012, the Department of Education (DOE) launched a significant process to reform their school siting guidelines in
response to AB32 (2006), and SB375 (2008). There was a "summit" at the start of the process that stressed the need for the
DOE to have policies consistent with the new, GHG reduction paradigm. The DOE subsequently conducted hearings and
initiated public outreach. The process stopped several years later with no explanation or announcement. Inquiries to the state
have either gone unanswered or were responded to with limited information. The school siting guidelines were never updated.
At the local level, the County has engaged on local school district issues on several occasions to ensure that transportation
safety, access, land use compatibility, and environmental law were adequately addressed with the purchase of and
development of new school sites.
Considering the challenges experienced with the development of land central to their core mission, educating youth, expanding
authority to include housing development raises concerns.
Staff recommends that the Board of Supervisors send a letter to the author (attached) expresssing support for the concept due to the
acute housing crisis but also requesting an amendment that would exclude areas outside a local jurisdiction's voter-approved or
Board/Council-adopted urban limit line, urban growth boundary, urban service area, urban development boundary, urban/rural
Board/Council-adopted urban limit line, urban growth boundary, urban service area, urban development boundary, urban/rural
boundary, or the equivalent and to engage like-minded organizations in order to build a coalition in support of this position.

CONSEQUENCE OF NEGATIVE ACTION: There is currently no opposition to AB 2295 that cites loss of local land use
authority or the undermining of coherent land development patterns as a concern. If the recommended action is not taken, the bill
could pass, undermining the County's decades long growth management effort. In addition, it would be reasonable to expect
secondary, unintended consequences of the bill related to longer term land speculation and development through the formation of
developer/school district partnerships to proactively use this new authority.

OPPOSE Unless Amended
Dear Assemblymember Bloom,
On behalf of the Contra Costa County Board of Supervisors, I am writing regarding the
subject bill which would require that a housing development project be deemed an
authorized use on any real property owned by a local educational agency (LEA) if it
meets specified occupancy, affordability, and planning criteria. The Board is currently
opposed to the bill unless it is amended consistent with revisions described below.
In its current state the bill conflicts with several significant policies, local and state. At the
local level, Contra Costa and many other jurisdictions have enacted an Urban Limit Line
(ULL), Urban Growth Boundary (UGB), or the equivalent. Contra Costa’s ULL has been
in place for over 30 years and has twice been reaffirmed by voters countywide. The line
was placed strategically to delineate adequate developable land to accommodate growth
within the ULL and preserve farmland and habitat outside the line. Our ULL policy
includes a review requirement to ensure an adequate supply of developable land over
time. Contra Costa’s most recent review included representatives of the building industry
who did not take issue with the ULL. The finding that there was an adequate supply of
developable land was uncontested during the review process.
Further policy conflict can be found relative to the State’s own greenhouse gas (GHG)
reduction legislation (AB32 [2006], SB 375 [2008], SB 743 [2013]). Local jurisdictions
faithfully responded to these legislative directives by implementing policy changes and
modifying land development patterns to reduce GHGs. The subject bill would contradict
this prior direction and upend recent gains.
California deserves a more coherent approach to land development regulations.

We support efforts to increase the housing supply and believe that school districts should
have an enhanced ability to develop homes on their property so long as the land is
within an urban limit line. The Board respectfully requests that the subject bill remove
the exemptions established in AB 2295 for land outside an adopted ULL/UGB or the
equivalent.
If you have any questions regarding this letter, please contact the County’s legislative
advocate, Jim Gross (JGross@nmgovlaw.com), or the County’s Principal Planner, John

RECOMMENDATION(S):
ADOPT Position Adjustment Resolution No. 25709 to reallocate the salary on the salary schedule for the classification of Hazardous Materials
Technician (V4WF) (represented) at salary plan and grade T35-1409 from ($5,257 - $5,796) to salary plan and grade T35-1409 ($5,257 -
$6,390) in the Health Services Department.
FISCAL IMPACT:
Upon approval, this action has an annual cost of approximately $21,054 with pension costs of $8,164 already included. Since the Hazardous
Materials Program is 100% fee based, there will not be an impact to the County' s General Fund. The cost will be offset entirely with Certified
Unified Program Agency Permit Fees.
BACKGROUND:
This classification handles more technical and advanced tasks such as performing research to determine the chemical compatibility of personal
protective equipment and participates in the Incident Response Administrative Team and the CCHMP Health & Safety Committee, calibrate and
maintain instruments, maintain the County’s Hazardous Materials trucks and response vehicles and find cost effective methods of proper
disposal. Therefore, the department is requesting

Subject:Reallocate the Salary of the Classification of Hazardous Materials Technician on the Salary Schedule in the Health Services

BACKGROUND: (CONT'D)
for two additional steps in the salary structure. While conducting a salary survey to determine if adding pay steps in the salary structure is
appropriate, Santa Clara County was the only comparable classification found within the Bay Area. To retain competent and highly skilled
Hazardous Materials Technicians, the recommendation to add two additional pay steps to this classification is fair and appropriate. Adding
these two additional pay steps will promote upward mobility towards the Hazardous Materials Specialist classification series, prevent
retention issues, and have a competitive salary structure.
CONSEQUENCE OF NEGATIVE ACTION:
If this action is not approved, the Hazardous Materials Program will not be able to retain qualified staff which will adversely impact the
services of the program.

RECOMMENDATION(S):
ADOPT Position Adjustment Resolution No. 25853 to reallocate the salary of the Assistant Agricultural Commissioner and Sealer of Weights
and Measures-Exempt (BAB1) classification from salary plan and grade level B85 1923 ($9,099 - $11,060) to salary plan and grade level
B85-1923 ($9,509 - $11,558) in the Agriculture, Weights and Measures Department.
FISCAL IMPACT:
Upon approval, this action will result in an additional annual General Fund cost of approximately $8,000.
BACKGROUND:
The Agriculture, Weights and Measures Department has had difficulty recruiting for the Assistant Agricultural Commissioner and Sealer of
Weights and Measures position since it has been vacated. The person whom previously held the position left the County for a higher paying
salary and position. A salary study concluded the current salary was 4.5% below the mean. Since this position requires two State licenses, it has
been difficult to attract competitive candidates with the current salary. The most recent recruitment didn't yield a large pool of candidates, and
thus increasing the salary would make Contra Costa's Agricultural Department more competitive with other counties.

RECOMMENDATION(S):
ADOPT Position Adjustment Resolution No. 25932 to cancel one (1) vacant Clerical Supervisor (JWHF) position #14950 at salary plan and
grade K6X-1290 ($4,848 - $6,191), and add one (1) Account Clerk Supervisor (JDHD) position at salary plan and grade K6X-1340 ($5,094 -
$6,505) in the Finance division of the Health Services Department. (Represented)
FISCAL IMPACT:
Upon approval, this action will result in an annual cost increase of approximately $5,734, with pension costs of $1,462 already included. The
increased salary and benefit cost will be fully funded by Hospital Enterprise Fund I revenues.
BACKGROUND:
The majority (95%) of staff in the Patient Accounting unit of the Health Services department are Account Clerks, who have been receiving
supervision from a Clerical Supervisor -- due to the nature of the work, Health Services is requesting to add an Account Clerk Supervisor
position to replace the vacant Clerical Supervisor position in overseeing the day-to-day work of the Account Clerks. This would also provide
potential growth opportunity for our Account Clerk staff, encouraging career progression and retention within the department.
CONSEQUENCE OF NEGATIVE ACTION:
If not approved, this unit will not have a supervisor with the knowledge and background needed to appropriately support the functions of the
Patient Accounting Unit.

BACKGROUND: (CONT'D)
specialization in talent searches within the airport industry. Not only did outreach efforts include traditional recruitment brochures, but also
electronic recruiting ads placed on specifically targeted websites and direct sourcing efforts to recruit the best qualified candidates.
Recruitment efforts resulted in twelve (12) applications for further consideration. Applications were screened and six (6) candidates were
invited to participate in the final interviews that took place in early March 2022. The interview panel was composed of key stakeholders from
the Public Works Department, the Aviation Advisory Committee and County Administration. Based on the recommendations of the review
panel and of the County Administrator, Greg Baer was selected for the position of Director of Airports – Exempt.
Mr. Baer holds a Master’s Degree in Public Administration from Sonoma State University, a Bachelor’s of Science Degree in Aviation, with an
option in Management, a Business Minor from San Jose State University and a Certificate in Construction Management from UC Davis. Since
November 2016, Mr. Baer has served in multiple capacities with Napa County, with his most recent assignment as Airport Manager beginning
May 2018. In addition to overall responsibility for airport operations, he was also responsible for supervising and directing $18 million in
Capital Improvement projects. Mr. Baer is an active member of both the American Association of Airport Executives (AAAE) and the
Southwest Chapter of the American Association of Airport Executives (SWAAAE). As a successful applicant, Mr. Baer is qualified to serve as
the County’s Director of Airports-Exempt.
CONSEQUENCE OF NEGATIVE ACTION:
The Director of Airports-Exempt position will remain vacant, leaving a critical management vacancy within the Airports Division of the Public
Works Department.
RECOMMENDATION(S):
APPROVE and AUTHORIZE the Health Services Director, or designee, to execute on behalf of the County Grant Agreement #28-882-6 with
Sutter Bay Hospitals, including indemnification, to pay the County an amount not to exceed $100,000 for the County’s Coordinated Outreach,
Referral and Engagement (C.O.R.E.) program to provide homeless outreach services for the period from January 1, 2022 through December 31,
2022.
FISCAL IMPACT:
Approval of this grant agreement will result in an amount of $100,000 for the County’s C.O.R.E. program for homeless outreach. No County
match required.
BACKGROUND:
The Concord Shelter in conjunction with the County’s C.O.R.E. program is part of a comprehensive strategy to provide outreach and housing
and services to the homeless in Contra Costa County. The C.O.R.E. program will dedicate three beds within the Concord Shelter for Sutter Bay
Hospital patients who are homeless, identified to be too low acuity to access the Respite Shelter program, capable of self-care and are
appropriate for placement in regular shelter programs. These homeless residents are allowed stay up to 120 days.
On June 8, 2021, the Board of Supervisors approved Grant Agreement #28-882-5 with Sutter Bay Hospitals in an amount not to exceed
$75,000 to provide funding to support the County’s C.O.R.E. program to provide homeless outreach services for homeless residents for the
period from January 1, 2021 through December 31, 2021.
Approval of Grant Agreement #28-882-6 will allow the County to receive funds for the County’s C.O.R.E. program through December 31,
2022. The County is agreeing to indemnify and hold harmless the contractor for claims arising out of the County’s performance under this
contract.
CONSEQUENCE OF NEGATIVE ACTION:
If this grant agreement is not approved, the County will not receive funding to support homeless residents being discharged from Sutter Bay
Hospitals in Concord.

Subject:Bringing Families Homes Program Allocation
BACKGROUND: (CONT'D)
an All County Welfare Directors Letter announcing the FY 2021-2022 noncompetitive allocation for all fifty-eight (58) counties and one (1)
continuing tribe in the amount of $82.875 million based on a local need methodology. Contra Costa County Employment and Human Services
Department (EHSD) Children & Family Services (CFS) Bureau has been allocated $1,079,500.
Funds will be used to help eligible families receiving child welfare services to secure and maintain housing through BFH, including, but not
limited to, Rapid Rehousing, Supportive Housing, Housing Navigation and Targeted Prevention Services. EHSD CFS will coordinate with
Contra Costa County Health, Housing, and Homeless Services (H3) as the local Continuum of Care to help implement the program and
collaborate with the greater homelessness response system and partners to link families to necessary services.
CONSEQUENCE OF NEGATIVE ACTION:
Without funding, the County will face an increased number of children brought into foster care due to inadequate and/or lack of housing and
homeless prevention services for biological families.
CHILDREN'S IMPACT STATEMENT:
Funding resulting from this grant will support three of the five community outcomes established in the Children’s Report Card: 2) "Children and
Youth Healthy and Preparing for Productive Adulthood"; 3) “Families that are Economically Self Sufficient”; and 4) “Families that are Safe,
Stable and Nurturing”. This is accomplished by providing safe housing and housing supports to assist families and their children.
RECOMMENDATION(S):
APPROVE and AUTHORIZE the Clerk-Recorder, or designee, to execute a grant amendment with the California Secretary of State to extend
the term from June 30, 2022 through December 31, 2024 with no change to the reimbursement limit of $6,038,436 for the purchase of
replacement voting systems and technology.
FISCAL IMPACT:
Under the contract, the State matches the County's spending 3:1 on voting systems and technology replacement.
BACKGROUND:
In 2018, State funding became available for counties to replace voting systems and technology. In 2019, the County entered into a grant
agreement with the State for such monies in the amount of $3,647,000 with an expiration date of June 30, 2021. In 2020, the County entered
into a grant amendment with the State that increased the grant amount to $6,038,436 and extended the expiration date to June 30, 2022. Under
the proposed contract amendment, the grant agreement term would be extended through December 31, 2024 with no change to the
reimbursement limit. Monies provided to the County by the State under the grant agreement may be used by the County both retroactively for
reimbursement of allowable costs and for reimbursement of future purchases of voting equipment.
CONSEQUENCE OF NEGATIVE ACTION:
Should the County chose not to execute the grant contract, the County will not be reimbursed with State funds for 75% of any voting system
and equipment purchases made during the term extension period.

Subject:Receive Funding from the California Commission on the Status of Women and Girls Women’s Recovery Response Grant
BACKGROUND: (CONT'D)
On February 1, 2022, the Board of Supervisors approved and authorized the CCCWG to apply for the Women’s Recovery Response Grant
from the California Commission on the Status of Women and Girls (CCSWG) (C. 47 ). On March 15, 2022, CCSWG notified CCCWG that
the Contra Costa Commission has been selected for funding in the amount of $25,000 as part of the Women’s Recovery Response Grant
Program under the Communications Funding Category.
The grant funding will support CCCWG’s strategic communications efforts through the development and implementation of a
comprehensive communication plan. In order to connect more authentically with the community, CCCWG will utilize multiple levels of
engagement with the public, both digitally and via print media. By having a stronger social and traditional media presence, the CCCWG will
engage more effectively with the community and educate and inform women and girls of resources and support services available to them
throughout the County.
The funding will be deposited into the County Treasury and administered through Budget Unit 0135, org. 1151.
CONSEQUENCE OF NEGATIVE ACTION:
The Contra Costa Commission for Women and Girls will not receive California State Women’s Recovery Response Grant funding,
reducing local services to women and girls who have been disproportionately affected economically by the ongoing pandemic.

RECOMMENDATION(S):
APPROVE and AUTHORIZE the Human Resources Director, or designee, to execute a contract amendment with SmartERP Solutions, Inc., to
extend the term from April 30, 2022 through June 30, 2024 and increase the payment limit by $100,000 to a new payment limit of $460,000 for
the implementation,license and support of the SmartERP software.
FISCAL IMPACT:
The administrative cost of this contract extension for the annual fee is funded through the Benefits Administrative Fee which is charged out to
departments.
BACKGROUND:
The Human Resources Department is continually looking for ways to make processes and procedures more efficient and effective for County
departments and employees. One of these priorities is the creation of a centralized onboarding experience with foundational information
pertinent to all new hires as they begin working for Contra Costa County. In addition to these core materials, departments with specific
requirements will be able to add customized content. This will allow departments to provide a convenient and consistent process for new hire
onboarding.
In addition, improvement is needed in the merit step review process. Currently, each department runs a report to obtain a list of employees
scheduled for merit step review, which is then forwarded to the appropriate supervisor or manager to approve for each eligible employee. The
goal is to create an automated monthly process where managers/supervisors will receive an email listing all employees eligible for merit step
review which will be processed as a batch rather than individually. This will allow timely merit reviews and mitigate payroll errors due to late
review and approval.
Human Resources Information Systems (HRIS) staff will work with Smart ERP Solutions on these two improvement projects as well as gaining
the knowledge and skills necessary to pursue future projects independently. Smart ERP Solutions will provide professional services to the
County for implementation of the Smart Toolkits solution software which includes HR Automation functionality for Smart Onboarding and the
ability to build a workflow and approval path for merit increases. Smart ERP Solutions will add software into the County’s PeopleSoft
Development environment in order to automate HR forms for Smart Onboarding and merit increases including:

#74-535-7 with R.E.A.C.H. Project, a non-profit corporation, effective January 1, 2022, to amend Contract #74-535-6, to increase the payment
limit by $40,000, from $200,000 to a new payment limit of $240,000, with no change in the original term of July 1, 2021 through June 30, 2022.
FISCAL IMPACT:
Approval of this amendment will result in additional annual expenditures of up to $40,000 and will be funded 100% CalWORKS Alcohol and

BACKGROUND:
The County has been contracting with R.E.A.C.H. Project, since January 2017 to provide mental health services and substance abuse prevention

Medi-Cal eligible County residents, for the period July 1, 2021 through June 30, 2022.
The delay with brining this amendment request to the Board is due to the resurgence of COVID-19 earlier in the year, which has created service
interruptions, productivity declines and cash flow issues with the community based behavioral health service providers. Approval of this
amendment allows the need to maintain a viable service delivery network to ensure access to needed behavioral health services with the
County.

abuse prevention treatment services, through June 30, 2022.

BACKGROUND: (CONT'D)
On November 9, 2021, the Board of Supervisors approved a one-time payment for services requested by the Division and provided by the
Contractor in the amount of $150,569.30. The Division requested temporary specialty locum tenens physician services during the contract
period August 1, 2020 through July 31, 2021 that exceeded the contract payment limit of $1,600,000. The total contract expenditures of

was shifted to the contractor from a former temporary physician provider.
Approval of Contract #76-662-4 will allow the contractor to continue providing temporary physician staffing services and recruitment
services through July 31, 2022. The contract request to the Board was delayed due to the contractor not providing all of the required
documents to the department in a timely manner.

RECOMMENDATION(S):
1. RECEIVE the attached report from Sustainability Commission recommending the County consider establishing standards for low-carbon
concrete;
2. REFER the topic of low-carbon concrete standards to the Sustainability Committee.
FISCAL IMPACT:
At this time, the fiscal impact would be costs associated with staff time required to conduct a study on the adoption of low-carbon concrete
standards. Such staff costs are already budgeted.
BACKGROUND:
The responsibilities of the Contra Costa County Sustainability Commission include: (1) Provide advice to staff and the Board on successful
implementation of the Climate Action Plan, including suggestions on how that work can be performed more efficiently and effectively; (2)
Advise the Board on opportunities to realize equity and fairness across the diverse communities of Contra Costa County in sustainability
programs that support the Climate Action Plan; and (3) Provide suggestions to staff and the Board on how to better engage Contra Costa County
residents and businesses on sustainability issues and implementation of the Climate Action Plan.
The Sustainability Commission at its April 26, 2021 meeting received a report from Wes Sullens in his role as Director, Leadership in Energy
and Environmental Design (LEED), at the U.S. Green Building Council (USGBC). The report focused on USGBC’s green building rating
system and opportunities to integrate LEED principles into the County’s Climate Action Plan.
The Commission formed a working group to explore ideas and develop recommendations. At the June 28, 2021 meeting of the Sustainability
Commission, the Commission unanimously adopted four of the five recommendations brought forward by the working group. Those
recommendations were provided to the Board on August 3, 2021, and referred to and considered by the Sustainability Committee at its

Subject:Refer Topic of Low-Carbon Concrete Standards to the Sustainability Committee
BACKGROUND: (CONT'D)
At its February 28, 2022, meeting, the Sustainability Commission received a report from the working group on its final recommendation
regarding the use of low-carbon concrete in County construction projects, as well as in projects approved by the County. The attached
report describes that concrete accounts for approximately 8% of the world's manmade carbon dioxide (CO2) emissions, and that the
concrete industry has available low-carbon concrete mixes. The report states that Marin County and several Bay Area cities have adopted
building codes that require the use of low-carbon concrete mixes. It describes different strategies that could be used to reduce the amount of
carbon embodied, or captured, in concrete.
The Sustainability Commission recommends that the Board of Supervisors direct staff to study adoption of low-carbon concrete standards.
It further recommends that low-carbon concrete standards be implemented through reach codes that would apply to all new construction in
unincorporated Contra Costa County. Staff recommends this proposal be more thoroughly examined by the Sustainability Committee.
CONSEQUENCE OF NEGATIVE ACTION:
Failure to take action on the recommendations in the letter means the Board would be disregarding the advice of the Sustainability
Commission.

The problem
Concrete accounts for approximately 8% of the world’s manmade CO2 emissions.1 For
comparison, that is more than three times the global carbon emissions of the aviation industry
(2.5%).2 But unlike aviation, technologies for mitigating the climate impact of concrete are
currently available and economically competitive.
The concrete industry has been able to provide low-carbon concrete mixes for more than a
decade.3 What’s more, a cursory Internet search reveals that industry and publicly-funded
research is sharply focused on bringing lower-carbon and carbon-neutral products to the
market as rapidly as possible.4
The opportunity
Any local government strongly committed to reducing embodied carbon in our built
environment can start by adopting building codes that require the use of low-carbon
concrete mixes.5 Marin County and several Bay Area cities have already done so.6
The concrete industry is already responding to growing demand for less carbon-intensive
products. In September 2021, an industry -wide coalition, Concrete Action for Climate, formed
with the objective of delivering net-zero concrete to the world by 2050.7
Because public agencies buy up to a third of the concrete manufactured annually 8, local
governments have the market leverage that can accelerate the research and development of
low-carbon concrete.

reducing EC must tackle concrete use generally. That includes alternate structural methods (e.g. tall timber
construction) and engineering that minimizes concrete volume without any loss of strength or durability.

The obstacle
As we will show, delays in governments’ adoption of low-carbon concrete standards cannot
be attributed to lack of practical alternatives. Instead, the obstacle appears to be institutional
inertia. In June 2019, a University of California research group published a best practices
paper which offered its wide-angle perspective: “ Many local governments have not revised
their concrete specifications in years—leaving in place minimum cement content
requirements and other elements that are out of step with modern practices.”9
Multiple pathways to net-zero
Concrete is a mixture of cement, aggregate, sand, and water. It is the second-most used
substance in the world after water.10 Its global climate impact should compel regulatory
agencies, as it already has industry scientists and engineers, to explore every possible
approach to reducing concrete’s environmental costs.
There are four ways to reduce the embodied carbon 11 of concrete:
1. Reduce and decarbonize the heat energy required in the manufacturing of cement.
2. Reduce the amount of cement in concrete by replacing a portion of it with a less
carbon-intensive material that preserves or improves its strength and durability.
3. Substitute limestone aggregate with a synthetic, carbon-sequestering aggregate that
uses locally-sourced stone or recycled concrete rubble.
4. Blend captured CO2 into fresh concrete during mixing, thereby sequestering it from
the atmosphere.
The first approach focuses on the manufacturing of concrete, and can be implemented at
plants and quarries around the county. The following three approaches address the
composition and design of concrete mixes for specific applications, and generally take place
at ready-mix facilities. Local building codes can regulate those practices.
Reducing cement in concrete
Cement accounts for only 10-15% of concrete by weight but more than 90% of its CO2
emissions. Therefore, the most effective approach to reducing concrete’s global warming
potential is to substitute a portion of cement with less carbon-intensive materials that
perform as well or better. They are called substitute cementitious materials, or SCMs.
The most commonly used SCMs, or pozzolans, are fly ash and slag. They are products of fossil
fuel industries (coal-fired power plants and steel production, respectively). These materials are

Davis and Berkeley. June 2019.
10 Gagg, Colin R. "Cement and concrete as an engineering material: An historic appraisal and case study
analysis". Engineering Failure Analysis. 40: 114–140
11 The major sources of embodied carbon in concrete are the fossil fuel energy expended for the quarrying of
limestone, heating the limestone to extremely high temperatures, and the long-distance transportation of cement
and aggregate. A second major source of emissions is the CO2 and heat released during the curing process.

cheap, abundant, and meet engineering requirements for most applications. However, fly ash
and slag are not without potential challenges.
In a 2021 paper 12, the Sierra Club stated two concerns about fly ash and slag. First, they may
present health risks to workers and nearby residents from air-borne dispersion at or near
concrete mixing facilities. Secondly, their use monetizes a product of fossil fuel industries.
Based on conversations with a professor of public health 13 and the sustainability director for a
major concrete supplier 14, we believe that these concerns have not been sufficiently
documented to warrant a delay in the adoption of low-carbon concrete standards, given the
overwhelming health and environmental benefits of rapid greenhouse gas reductions. We
must not allow the perfect to be the enemy of the good.
Alternatives SCMs
The supply of fly ash will dwindle as coal-fired power plants are phased out. But other SCMs
that are not by-products of fossil fuel industries are available. A few examples are volcanic ash,
calcined clay (mentioned in the Sierra Club paper); silica fume and rice hull ash (Berkeley
Municipal Code, chapter 19.37.04).
Recycled glass may be the most environmentally positive SCM. If its use becomes widespread,
the practice will divert thousands of tons of waste glass from landfills—a significant step
toward achieving a circular economy in a key industrial sector.15 Last year a Connecticut plant
began manufacturing a concrete-grade pozzolan from post-consumer glass.16 We are not
aware of plans to launch a similar facility on the West Coast.
Owing to the growing importance that investors place on Environmental, Social and
Governance (ESG) factors, business and environmental considerations are coming into closer
alignment. 17 Concrete companies will choose SCMs with lower carbon footprints as long as
their supply is reliable, their performance meets engineering requirements, and their price is
competitive.
12 “Sierra Club Guidance: Cement Manufacturing,” June 2021.
13 Professor Emeritus Thomas McKone of the UC Berkeley School of Public Health stated that the most significant
pollutant from grinding and handling fly ash is PM2.5. But, he said, other SCMs, such as volcanic ash or limestone,
pose similar risks so proper handling practices must be followed in any case.
Embedded in concrete, fly ash and slag are not “bio-available.” Professor McKone said their use as SCMs is,
therefore, a safer “disposal” method than heaping the material on the ground, where their toxic components can
contaminate soil and leach into groundwater. Phone conversation.

Two promising technologies sequester CO2. obtained from current industrial operations. Blue
Planet’s synthetic carbon-sequestering aggregate replaces limestone gravel, transported by
rail thousands of miles from quarry sites. The company has applied for a permit to open a
plant in Pittsburg. The Blue Planet technology combines captured CO2 with calcium sourced
from waste. Its website states “[Its] aggregate is so carbon negative that it offsets all the
emissions from the cement in the concrete, making the mix carbon negative.”18
CarbonCure is another proprietary technology for sequestering carbon. The method involves
injection of captured CO₂ into fresh concrete during mixing. This technique can also be used
in production of precast concrete and concrete block. According its website, CarbonCure
improves concrete’s compressive strength and significantly reduces its carbon footprint.19
A number of other technologies for reducing the global warming potential of concrete are
emerging, but these two are locally available and ready for use.20
Approach to regulation
These methods are not stand-alone mitigations. Used together, they can produce concrete
that is carbon-negative.21 In other words, they can offset more carbon through carbon
capture, sequestration, or avoidance, than they emit.
Given the ongoing, rapid development of new technologies, the most practical approach to
regulating embodied carbon must be flexible: establish standards that limit total embodied
carbon, or global warming potential, of a project. Project applicants will then choose the most
appropriate way to meet to meet those standards, based on technical requirements, design
considerations, cost, and availability.
The low-carbon concrete requirements developed by the County of Marin 22 as “model code”
under a BAAQMD grant, take this approach. In partnership with stakeholders across the
region, the County established codes that provide for two alternative compliance pathways:23
1.Limit the maximum allowable amount of cement (specified in lbs/yd3) necessary to
achieve the compressive strength required for specific applications; or,
2.Limit the maximum embodied carbon (kg CO2e/m3) of the total concrete usage within
a project. This value is calculated using the Environmental Product Declarations (EPDs)
for particular concrete mix designs.

Low-Carbon Concrete Recommendation
February 2022

Compliance under the first pathway is achieved, in essence, by following a recipe. Because it
is simple, most contractors follow this pathway.
The second pathway, though more complex, leaves the door open for meeting the standards
through any combination of SCMs, synthetic aggregate, CO2 injection, or even cement
substitutes that may be on the horizon. It seems that the Marin low-carbon requirement is
future-proofed.
Our recommendation
Consider the landscape before us. We see:
• A growing number of jurisdictions adopting low-carbon concrete standards;
• An industry that already offers lower-carbon products and is incentivized to deliver
still lower-carbon materials and technologies;
• Practical and flexible low-carbon concrete building codes currently in effect;
• And especially, a rise of more than 6% in global greenhouse gas emissions in 2021,
compared to the previous year.24
Against that background, we urge the Sustainability Commission to recommend that the
Board of Supervisors direct staff to study adoption of low-carbon concrete standards.
We further recommend that these standards be implemented through reach codes that
would apply to all new construction in unincorporated Contra Costa.

Emissions Bounced Back Sharply in 2021,” New York Times, January 10, 2022.
RECOMMENDATION(S):
ACCEPT the February 2022 update of the operations of the Employment and Human Services Department, Community Services Bureau, as
recommended by the Employment and Human Services Director.
FISCAL IMPACT:
There is no fiscal impact.
BACKGROUND:
The Employment and Human Services Department submits a monthly report to the Contra Costa County Board of Supervisors (BOS) to ensure
ongoing communication and updates to the County Administrator and BOS regarding any and all issues pertaining to the Head Start Program
and Community Services Bureau.

News /Accomplishments
On February 23, 2022, all preschool teaching staff and Site Supervisors attended a
refresher training on “Project Approach” conducted by Michelle Grant -Groves from i3
Institute. The purpose of this refresher training was to provide participants with
practical information and an overview of inquiry project -based learning and strategies
for teachers to implement in their classrooms. The presenter provided the connection
to California Preschool Learning Foundations, including observation, documentation,
and refle ction. She also demonstrated the webbing process and introduction to
provocations and projects. Participants were engaged in reflection and discussion to
support their learning. We provided this refresher training to empower teachers to feel
more motivated to conduct more project-based learning with their preschoolers and to
balance with teacher-directed learning.
The Community Services Bureau (CSB) celebrated World Read Aloud Day on
Wednesday, February 2, 2022, by virtually reading to children i n the classrooms! Staff
also recorded themselves reading their favorite children’s book and shared the
recording on our CSB YouTube channel and on social media sites. For young children,
being read to for 20 minutes a day makes a big difference as they are exposed to a vast
quantity of words! We hope this inspires everyone to take time out of their hectic days
to enjoy a bit of reading.
Allocations for the remaining Measure X funds will be awarded to chil dcare and
childcare providers. This is such wonderful news and a great success, as funds were not
previously allocated for childcare. Congratulations to the Community members, and
families who advocated and spoke on the importance of funding childcare in Contra
Costa.
CSB re -designed its CPR and First Aid class to a hybrid model where the instru ctional
portion will be on Zoom, and the practicum will be in -person. This will minimize time
away from the classroom, providing greater flexibility.
CSB conducted its Semi -Annual Monitoring report for the period of July 2021 through
December 2021. Monitoring activities included directly operated centers, partner
centers, and the delegate agency. The report highlights strengths and areas needing
improvement in the areas of file review, family childcare homes, and environment rating
scale. Please refer to attachment 09_CSB 2021-2022 Semi-Annual Monitoring Report

with support from EHSD Personnel and HR.
II. Emerging Issues and Hot Topics:
The Office of Head Start (OHS) conducted a hybrid virtual/onsite monitoring
review of CSB the week of February 22, 2022. This Special Review was
conducted to assess the program and fiscal compliance of CSB’s Head Start and
Early Head Start program as the OHS Regional Office is aware of multiple
conce rns regarding CSB’s Delegate Agency , First Baptist Head Start. The review
team consisted of five on -site and two off -site monitors who conducted a series
of interviews, document reviews, and center observations to determine CSB’s
compliance with Head Start Program Performance Standards and relevant fiscal
regulations. With a focus on health and safety, ten Head Start/Early Head Start
centers were monitored, including directly operated, partners, and delegate
sites.
Although a final report is not anticipated for up to 60 days, the review team
provided informal feedback to conclude the review. The reviewers were very
impressed with the centers; not only with cleanliness but especially with the
passion shown by the teaching staff. It has been communicated that some
improvement is needed in the areas of governance, health/safety and

supervision, and fiscal. CSB has already begun to strengthen these areas. The
review team acknowledged CSB’s many strengths as a program and that any
potential concerns were correctable.
Effective as of February 2022, the Administration For Children and Families
(ACF) consolidated the grant for the Early Head Start -Child Care Partnership
Program (CCP) with the regular Early Head Start Program (EHS) to streamline
the monitoring of program objectives, grant budget application, and program
measures. Please refer to attachment 04_CSB EHS Financial Report – January
2022 to review the consolidated report .
*EHS and EHS-CCP are now reported as one combined enrollment percentage effective January 2022 as
grants have been consolidated
** ARPA LIHEAP is a new contract that was executed in October for clients impacted by COVID -19 wi th
large past due energy bills.

EXECUTIVE SUMMARY
The Contra Costa County Area Agency on Aging (AAA) is pleased to present its Area
Plan Update for Fiscal Year 2022-2023 (APU 2022-23). Contra Costa County is
designated as Planning and Service Area #7 (PSA 7) in the State of California,
overseen by a local AAA responsible for planning, coordinating, implementing, and
funding programs and services for older persons, adults with disabilities, and family
caregivers. APU 2022-23 is the AAA’s annual update to its current four-year Area Plan
(2020-2024) that describes changes in the needs of its client population and the
priorities, strategies, and activities planned in the coming year to address these
concerns.
Conforming to the California Department of Aging’s (CDA) guidelines on the
development of updates to the Area Plan, only the sections that have changes from
prior submissions are included in APU 2022-23. In addition to the required updates on
objectives, service unit plans, disaster preparedness, etc., new information is presented
in the APU 2022-23 that includes the following:
• New demographic data from the 2020 Census and 2022 CDA demographic
projections (Section 2)
• Data on low-income populations age 60 years and older by race and location
(section 2)
• Implementation of the Master Plan for Aging in Contra Costa County (Section 4)
• Analysis of need during the pandemic years using Information and Assistance
and 2-1-1 calls data (Section 5)
• Prioritization of services procured for the Older Americans Act Title IIIB
Supportive Services (Section 5)
The disruption of the pandemic on the lives of every individual has been enormous, yet
it revealed our resilience, ingenuity, and ability to come together as a community of
service providers and neighbors to support those who are most vulnerable among us.
The pandemic exposed the fissures and inequities in our system, which had been there
all along, but now has a platform to discuss and create meaningful change.
The Master Plan for Aging (MPA) provides opportunities to make aging for all
Californians equitable, inclusive, affordable, and effective. As the coordinator of the
local implementation of the MPA, the Area Agency on Aging, with support from the
Board of Supervisors through Measure X funding, the County demonstrates its
commitment and leadership in ensuring that Contra Costa County residents of all ages
and abilities feel safe, healthy, and purposeful.

SECTION 2. DESCRIPTION OF THE PLANNING AND SERVICE AREA PSA 7
The 2020 Census ranks Contra Costa as the ninth most populous county in California,
numbering 1,165,927 residents, which represents an eleven percent increase from
2010. Contra Costa is a diverse community and has increasingly become more so in the
last decade, registering a diversity index of 73% in 2020, which measures the
probability that two people chosen at random will be from different racial and ethnicity
groups. Contra Costa’s diversity ranking moved up from eighth place out of 58 counties
in California in 2010 to fourth place in 2020.
According to the 2022 California Department of Aging (CDA) Population Demographic
Projections, a data set used by the State to establish the Intrastate Funding Formula
and calculate funding allocations for each county, Contra Costa County’s residents age
60 and older show the following characteristics:
CHARACTERISTIC TOTAL % of 60+
Population
Total Population age 60 and over 304,792 100%
Non-Minority 137,714 45%
Minority 167,078 55%
Non-English-Speaking 6,315 2%
Low-Income 21,465 7%
Geographically Isolated 1,769 1%
Lives Alone 48,180 16%
Central to the role of the AAA, and as required by the State, is the prioritization of
programs and services to targeted groups, including older adults who are low-income
and/or are from communities of color. The Census Bureau defines household income
that is at or below 100% of the Federal Poverty Level as “in poverty.”
An exploration of CalWIN data1 found 45,230 Contra Costa residents aged 60 and over
currently active in Medi-Cal, CalFresh, or both programs. Due to the limited data
available through the U.S. Census for the population of interest, Medi-Cal and CalFresh
recipient data was used as a proxy to determine low-income status by race among
individuals age 60 and older. It is important to note that both Medi-Cal and CalFresh
eligibility rules may allow specific individuals to qualify even if their income exceeds
100% of the Federal Poverty Level. The presence of these eligibility rules may explain
the higher number of persons age 60+ (45,230 people) presently enrolled in Medi-Cal
and CalFresh, compared to the Census estimates of 16,066 individuals in this cohort
(+/- 1,082 margin of error) who are “below the poverty level.” The following table shows
the recipients of Medi-Cal and CalFresh in PSA 7 age 60 years and older broken down
by primary race and ethnicity categories. The data suggests a slight overrepresentation
of Black/African American and Asian recipients of Medi-Cal and CalFresh who are age
60+, compared to the county population.

Critical to planning and targeting of programs and services is knowing where to direct
efforts to maximize impact and outcomes. The map below shows that Richmond,
Antioch, Concord, and Pittsburg have the highest counts of age 60 and over Medi-Cal
and CalFresh recipients in the county. These hot spots deserve special attention, and
outreach should be directed in these areas.

The increasing diversity of Contra Costa County is a source of pride and a reminder of
the criticality of foregrounding equity, inclusion, and cultural and language competency
in serving the community. The data on older residents presented in this section also
draws attention to older adults who are at-risk because they live alone, have lower
incomes, possess limited-English speaking abilities, and reside in geographically
isolated areas. Governor Gavin Newsom’s passage of Executive Order N-14-19 in
June 2019 that catalyzed the development of the Master Plan for Aging (MPA) validates
the importance of addressing these issues and activates local communities to take
action.

SECTION 4. PLANNING PROCESS/ESTABLISHING PRIORITIES PSA 7
The Master Plan for Aging is a 10-year blueprint to prepare California for its rapidly
graying population and to maintain its leadership in promoting a healthy and equitable
aging for all Californians. This vision will be accomplished through the MPA’s five bold
goals:
• Housing for all ages and stages
• Health reimagined
• Equity and inclusion, not isolation
• Caregiving that works
• Affording aging
On June 24, 2021, the MPA was introduced in Contra Costa at a forum that drew more
than 150 stakeholders representing public, private, nonprofit, and elected office. Fifteen
local priorities in support of the MPA’s five bold goals were identified by stakeholders.
Key themes that emerged from the identified priorities are as follows:
• Address affordability, availability, and accessibility of housing, supportive
services, food and nutrition, transportation, and other resources for older adults,
persons with disabilities, and family caregivers.
• Develop the workforce by providing equitable living wage for paid caregivers,
developing geriatric training, and creating certificate programs for professionals.
• Expand choices and options for various housing types, alternative living
arrangements, in-home/out-of-home homecare, end-of-life care, and community
development/City planning, permitting and building.
• Reframe attitudes, beliefs, and behaviors through anti-ageism, anti-ableism,
and caregiver awareness campaigns that also examine intersecting issues.
• Prioritize at-risk and hidden populations including low- to very-low income
seniors, persons with disabilities, and middle-income individuals who do not
qualify for public programs yet cannot afford to pay out-of-pocket for services.
• Develop data infrastructure and systems to cross-share information among
providers working with clients and consumers.
Contra Costa is in a unique position to successfully implement the MPA. On November
16, 2021, the Board of Supervisors adopted the Measure X policy and funding allocation
expenditure plan, which includes $1.25 million in the first year and $2 million annually
thereafter to support the local implementation of the MPA. Measure X is a half-cent
sales tax approved by Contra Costa County voters in November 2020 to generate
revenue for essential services and to support vulnerable populations.
The AAA has been delegated to coordinate the implementation of the MPA locally.
Measure X funding will be used to develop the Contra Costa County MPA Local
Playbook, which involves: (1) engaging in a year-long planning process to set the
9
groundwork for the local implementation of the MPA and develop a plan; (2)
strengthening the capacity of the service provider network through organizational
development trainings and direct funding of programs and services; and (3) identifying,
funding, and implementing initiatives to provide a viable and sustainable path forward
for older adults and persons with disabilities in the community.
A Contra Costa County IMPACT Steering Committee, comprised of leaders and
decision makers from various County departments, community-based agencies, elected
offices, and advocacy groups, had been established. Subcommittees are currently
forming to address specific priority areas and establish approaches and initiatives to
enable Contra Costa residents of all abilities to reach their full potential as they age.
10
SECTION 5. NEEDS ASSESSMENT PSA 7
At least once every four years, the AAA is required to release an open invitation to
solicit proposals from qualified community-based agencies to procure goods and
services funded under the Older Americans Act (OAA). Supportive Services funded
under the OAA Title IIIB came due for solicitation, and the AAA issued a Request for
Proposal (RFP) in March 2022.
To ensure that services procured in the Title IIIB Supportive Services RFP are relevant
and responsive to current needs, the AAA conducted an analysis of calls data from the
AAA’s Information and Assistance (I&A) program and 2-1-1 to determine the services
and resources community members inquired most about since the AAA’s last
countywide needs assessment in 2019. Of special interest is the pandemic’s impact on
the needs of residents in the last two years. Table 1 shows the most sought after
services prior to and during the pandemic.
Table 1. Top Service Needs Based on I&A and 2-1-1 Calls Data
Services Sought 2018-19 2019-20 2020-21
Homeless Services 12,145 9,011 6,852

Legal Services 1,671 1,598 1,861
Substance Use Services 1,340 1,293 1,145
Senior Services (general) 752 1,922 1,026
Disability Services (general) 404 405 883
Transportation 1,342 804 471
Caregiver Support 722 529 432
Homecare/Home Health 260 141 210
Case Management 231 96 141
Highlights of calls data results presented in Table 1 are as follows:
• The predominance of calls for homeless services may be skewed by 2-1-1 data,
which serves as the Coordinated Entry System for the unhoused population in
the county.
• The need for financial assistance and housing support have increased in the last
two years, possibly due to the impact of COVID-19 on the economic security of
many Contra Costa residents.
• Calls for food assistance more than doubled during the first year of the pandemic
and has since stabilized to pre-COVID levels. Nutrition services, particularly for
home-delivered meals, received major funding boost from federal and state
11
sources during the pandemic, including the CARES Act, Family First Coronavirus
Response Act, and the Great Plates Delivered program.
• Legal services remain a critical need.
• Persons with disabilities needed a lot of support this past year, registering a
doubling of calls compared to the last two years.
• The reduction of calls for transportation during the pandemic years may be
deceiving. COVID-19 has immobilized seniors’ participation in community
activities. Places frequented by seniors, including senior centers and congregate
meal sites, have remained closed.
• The reduction of calls for family caregiver support during the pandemic should
also be interpreted with caution. Community-based supportive services for
caregivers all but ceased during the pandemic. Some family members shifted to
remote work, providing extra support for their loved ones in need of care at
home, but this came at a great cost to their physical and mental health.
• The AAA’s 2019 needs assessment identified case management and homecare
support as a need, and calls data from the last two years have confirmed
continued demand for these services.
The stresses of the pandemic on older adults, family caregivers, and persons with
disabilities are clearly visible from the calls for resources and supports people have
made in the last two years. The disproportionality of the impact of the pandemic on
communities of color, caregivers, older adults, and persons with disabilities exposed the
vulnerabilities of a system plagued by chronic underfunding and the entrenched
institutional biases that have marginalized certain populations for decades.
Using the results of the calls data, the AAA established priorities for the procurement of
the following OAA Title IIIB Supportive Services:
• Adult Day Care
• Adult Day Health
• Assisted Transportation
• Case Management
• Homecare
• Legal Assistance
• Telephone Reassurance
• Visiting
Lessons learned from the pandemic reaffirmed the need for continued targeting of
services for low-income, geographically isolated, limited English-proficient, and racial
and ethnic minority populations. These considerations were stressed in the RFP. The
AAA also reassessed the reimbursement rates for these services by gathering
information from other counties to inform the current procurement and help set equitable
compensation rates that supports the viability of providers.

The following must be discussed at each Public Hearing conducted during the
planning cycle:
1. Summarize the outreach efforts used in seeking input into the Area Plan from
institutionalized, homebound, and/or disabled older individuals.
Notice of the public hearing was posted in various social media outlets 30 days prior to
the event. The AAA also sent an e-mail blast to all service providers on its master list
and encouraged them to promote to their clients. The AAA reached out to Empowered
Aging, the Long-Term Care Ombudsman provider in PSA 7, to help promote the public
hearing at facilities throughout the county and encourage participation from residents.
AAA staff has been announcing the public hearing at various community meetings,
including the West County Senior Coalition, East County Senior Coalition, and Seniors
and Adults with Disabilities Network.

5. Summarize the comments received concerning minimum percentages of Title IIIB funds
to meet the adequate proportion of funding for priority services.
Title IIIB adequate proportion of funding for priority services was discussed. No
comments were received.
6. List any other issues discussed or raised at the public hearing.
Questions raised at the public hearing and the responses provided are as follows:
• How is low-income defined, as it applies to Contra Costa County?
o The federal Older Americans Act governs the work of the AAA. As
such, the federal definition of low-income is used, which is at or below
100% of the federal poverty level. Given the higher cost of living in
Contra Costa County, the inadequacy of using the federal definition
was acknowledged.
• What are the biggest changes from last year to this year?
o Last year was a bit chaotic due to the pandemic. The AAA received
increases in funding with few guidance and unclear reporting
requirements. There was an urgency to release the funding to assist
our client population immediately while trying to figure out how to
implement these new programs we’ve never done before, such as
Great Plates. Thank you to the AAA staff for trying their best under
the circumstances, even though they were stretched to the limit.
Kudos to everything they did.
• How do we get involved with the Master Plan for Aging subcommittees?
o The Contra Costa County IMPACT Steering Committee has
established some subcommittees and will finalize them at the next
meeting and identify players to serve on the subcommittees. Will soon
announce a launch event to tell folks about this work and seek
community participation.
• How is innovative defined?
o Anything that is new. Outside of the box thinking. Promising practices
that were successful in other communities that can be replicated in
Contra Costa.
14
Other comments provided at the public hearing include the following:
o Thank you for using “persons of color” vs. minority.
o Equity is addressed throughout the document. The tragic lessons learned from the pandemic are clearly documented. Thank you to AAA.
o The Master Plan for Aging implementation process is inclusive, thoughtful,
and grassroots. It is a time for hope. We are starting from behind, so we
are starting from broken. We will get to a stage of working, then to
thriving. The AAA director’s leadership and Aging and Adult Services
Bureau director’s commitment make this feel doable.
o Disappointing to still have such a little amount from Older Americans Act
funding from the federal level.
o We are not without challenges, but we are in a better place than we have
been. Thank you to the AAA team.
o Kudos to the AAA.
7. Note any changes to the Area Plan which were a result of input by attendees.
No changes were made to the Area Plan Update FY 2022-23 as a result of input from
attendees at the public hearing.

Goal #2
Goal: The AAA will promote the development for age-friendly communities, ensure
that community infrastructure fully and meaningfully includes older adults and

Rationale: AAA needs assessment, community forums, key informant results, and caller identified need
through the Information and Referral line indicate that access to affordable housing and transportation are
the highest priorities for older adults to remain living in their home communities. Contra Costa residents
will have access to the help they need to live in the homes and communities they choose as they age.

LONG-TERM CARE (LTC) OMBUDSMAN PROGRAM OUTCOMES
2020-2024 Four-Year Planning Cycle
As mandated by the Older Americans Act Reauthorization Act of 2016, the mission of the
LTC Ombudsman Program is to seek resolution of problems and advocate for the rights of
residents of LTC facilities with the goal of ensuring their dignity, quality of life, and quality of
care.
Each year during the four-year cycle, analysts from the Office of the State Long-Term Care
Ombudsman (OSLTCO) will forward baseline numbers to the AAA from the prior fiscal year
National Ombudsman Reporting System (NORS) data as entered into the Statewide
Ombudsman Program database by the local LTC Ombudsman Program and reported by the
OSTLCO in the State Annual Report to the Administration on Aging (AoA).
The AAA will establish targets each year in consultation with the local LTC Ombudsman
Program Coordinator. Use the yearly baseline data as the benchmark for determining yearly
targets. Refer to your local LTC Ombudsman Program’s last three years of AoA data for
historical trends. Targets should be reasonable and attainable based on current program
resources.
Complete all Measures and Targets for Outcomes 1-3;
Outcome 1. The problems and concerns of long-term care residents are solved
through complaint resolution and other services of the Ombudsman Program. Older

PSA 7
HEALTH INSURANCE COUNSELING AND ADVOCACY PROGRAM (HICAP)
SERVICE UNIT PLAN
CCR Article 3, Section 7300(d)
MULTIPLE PSA HICAPs: If you are a part of a multiple-PSA HICAP where two or more AAAs
enter into an agreement with one “Managing AAA,” to deliver HICAP services on their behalf to
eligible persons in their AAA, then each AAA is responsible for providing HICAP services in the
covered PSAs in a way that is agreed upon and equitable among the participating parties.
HICAP PAID LEGAL SERVICES: Complete this section if your Master Contract contains a
provision for using HICAP funds to provide HICAP Legal Services.
STATE & FEDERAL PERFORMANCE TARGETS: The Administration for Community Living
(ACL) establishes targets for the State Health Insurance Assistance Program (SHIP)/HICAP
performance measures (PMs). ACL introduced revisions to the SHIP PMs in late 2016 in
conjunction with the original funding announcement (ref HHS-2017-ACL-CIP-SAPG-0184) for
implementation with the release of the Notice of Award (Grant No. 90SAPG0052-01-01 issued
July 2017).
Using ACL’s approach, CDA HICAP provides State and Federal Performance Measures with
goal-oriented targets for each AAA’s Planning and Service Area (PSA). One change to all PMs
is the shift to county-level data. In general, the State and Federal Performance Measures
include the following:
PM 1.1 Clients Counseled ~ Number of finalized Intakes for clients/ beneficiaries that
received HICAP services
PM 1.2 Public and Media Events (PAM) ~ Number of completed PAM forms categorized
as “interactive” events
PM 2.1 Client Contacts ~ Percentage of one-on-one interactions with any Medicare
beneficiaries
PM 2.2 PAM Outreach Contacts ~ Percentage of persons reached through events
categorized as “interactive”
PM 2.3 Medicare Beneficiaries Under 65 ~ Percentage of one-on-one interactions with
Medicare beneficiaries under the age of 65
PM 2.4 Hard-to-Reach Contacts ~ Percentage of one-on-one interactions with “hard-to-
reach” Medicare beneficiaries designated as:
o PM 2.4a Low-income (LIS)
o PM 2.4b Rural
o PM 2.4c English Second Language (ESL)
PM 2.5 Enrollment Contacts ~ Percentage of contacts with one or more qualifying
enrollment topics discussed
41
AAA’s should demonstrate progress toward meeting or improving on the Performance
requirements established by CDA and ACL as is displayed annually on the HICAP State and
Federal Performance Measures tool located online at:
https://www.aging.ca.gov/Providers_and_Partners/Area_Agencies_on_Aging/#pp-planning.
(Reference CDA PM 17-11 for further discussion, including current HICAP Performance
Measures and Definitions).
For current and future planning, CDA requires each AAA ensure that HICAP service units and
related federal Annual Resource Report data are documented and verified complete/ finalized
in CDA’s Statewide HICAP Automated Reporting Program (SHARP) system per the existing
contractual reporting requirements. HICAP Service Units do not need to be input in the Area
Plan (with the exception of HICAP Paid Legal Services, where applicable).

SECTION 12. DISASTER PREPAREDNESS PSA 7
Disaster Preparation Planning Conducted for the 2020-2024 Planning Cycle Older
Americans Act Reauthorization Act of 2016, Section 306(a)(17); 310, CCR Title 22,
Sections 7529 (a)(4) and 7547, W&I Code Division 8.5, Sections 9625 and 9716,
CDAStandard Agreement, Exhibit E, Article 1, 22-25, Program Memo 10-29(P)
1. Describe how the AAA coordinates its disaster preparedness plans and activities with
local emergency response agencies, relief organizations, state and local governments,
and other organizations responsible for emergency preparedness and response as
required in OAA, Title III Section 310.
The AAA ensures the preparedness of its organization and staff to meet the
challenges of a disaster. The main responsibility of the AAA is to support the
emergency management community to ensure that the disaster-related needs of older
adults and persons with disabilities receive access to overall community disaster
planning services. The AAA is part of the Contra Costa County structure and therefore
conforms to the County’s overall plan for disaster response and preparedness. One
element of the County’s plan enforces the requirement of County staff, including AAA
staff, to serve as official disaster preparedness workers in accordance with Section
3100 of the California Government Code.
In response to COVID-19, the AAA partnered with the Family Caregiver Alliance and
the John Muir Community Health Fund to co-create and co-facilitate the Seniors and
Disabled Adults Network to ensure that older individuals, persons with disabilities, and
family caregivers continue to receive support and information during the pandemic.
The Network meets monthly to share information, problem-solve, and to support one
another as service providers during this challenging time. The County’s Public Health
Officer and staff attend the meetings to provide updates and share information about
cases, vaccine rollout, and public education campaigns to protect the community’s
most vulnerable populations. The Network continues to meet and is committed to
continuing efforts to share information and collaborate to address the needs of its
shared population post-pandemic. The AAA also partnered with the California
Department of Aging, Community Care Licensing, County Public Health, and the local
Ombudsman program to coordinate the distribution of over 26,000 test kits to more
than 600 long-term care, adult residential care, and mental health facilities in Contra
Costa County.
The AAA recognizes emergency preparedness and protection of older adults is a
priority given the PG&E power shut- offs/outages, high heat in parts of the county and
most recently, the COVID-19 pandemic. The pandemic disproportionality affected
olderadults, who were asked to shelter in place in mid-March. This affected their
ability to obtain and access supportive programs and services, including the ability to
purchase and obtain meals. Our organization serves as main point of access for
Meals on Wheels as a resource for meals and nutrition.
2. Identify each of the local Office of Emergency Services (OES) contact person(s) within
the PSA that the AAA will coordinate with in the event of a disaster (add additional
43
information as needed for each OES within the PSA):
Name Title Telephone email
Rick Kovar OES Manager Office: 925-655-0123 jcava001@so.cccounty.us
Julie Cavallero Senior Emergency
Planning Coordinator
Office: 925-655-0116 jcava001@so.cccounty.us
3. Identify the Disaster Response Coordinator within the AAA:
Name Title Telephone email
Anthony Macias Senior Staff Assistant Office: 925-602-4175 amacias@ehsd.cccounty.us
4. List critical services the AAA will continue to provide after a disaster and describe how
these services will be delivered:
Critical Services How Delivered?
a. Emergency shelters a. County staff will staff shelters
b. Meals on Wheels b. AAA staff will assist with meal delivery
c. I&A c. Services will continue to provider services
after a disaster. The program’s platform is
online and can be accessed remotely by
Social Workers (call center staff). Clients can
continue to call the central intake phone
number, and staff can pick-up the call from
any location.
d. Long-Term Care Ombudsman d. AAA to ensure that contractor continues
to provide services to residents during a
disaster. AAA to provide support to
contractor.
5. List any agencies with which the AAA has formal emergency preparation or response
agreements.
The AAA is housed within the Contra Costa County Employment and Human Services
Department which is responsible for care and shelter in the event of a major disaster.
It has formal agreements with the American Red Cross, The ContraCosta County
Office of Emergency Services, the Contra Costa County Health Department, and the
Contra Costa Sherriff’s Department.
6. Describe how the AAA will:
• Identify vulnerable populations - The AAA utilizes information obtained from the In-
Home Support Services program and the aging network in Contra Costa County to
identify vulnerable at-risk individuals. The aging network consists of a collaboration of
Ombudsman Services, AAA contractors, and non-profit organizations whose purposes is
to serve and advocate for older adults.
44
• Follow-up with these vulnerable populations after a disaster event - Protocols are in
place to identify at risk populations and arrange for shelter care for those with special
needs. AAA works with the Ombudsman Program to ensure skilled nursing facilities,
assisted living facilities, and residential care homes provide for their clients, residents,
and patients during and after a disaster.
45
SECTION 13. PRIORITY SERVICES PSA 7
2020-2024 Four-Year Planning Cycle
Funding for Access, In-Home Services, and Legal Assistance
The CCR, Article 3, Section 7312, requires the AAA to allocate an “adequate proportion”
of federal funds to provide Access, In-Home Services, and Legal Assistance in the PSA.
The annual minimum allocation is determined by the AAA through the planning process.
The minimum percentages of applicable Title III B funds5 listed below have been
identified for annual expenditure throughout the four-year planning period. These
percentages are based on needs assessment findings, resources available within the
PSA, and discussions at public hearings on the Area Plan.
Category of Service and the Percentage of Title III B Funds expended in/or to be
expended in FY 2020-21 through FY 2023-2024
Access:
Transportation, Assisted Transportation, Case Management, Information and
Assistance, Outreach, Comprehensive Assessment, Health, Mental Health, and Public
Information
2020-21 20 % 21-22 20 % 22-23 20 % 23-24 %

Legal Advice, Representation, Assistance to the Ombudsman Program and Involvement
in the Private Bar
2020-21 11 % 21-22 11 % 22-23 11 % 23-24 %
Explain how allocations are justified and how they are determined to be sufficient to meet the
need for the service within the PSA. 7
The AAA conducted an analysis of calls to I&A and 2-1-1 for the last two years during the pandemic to
inform the prioritization of services for the Title IIIB RFP issued in March 2022. Based on the analysis,
Case Management and Homemaker services were added as new services funded through Title IIIB.
Though ARPA funds were used to augment available funds and increase services units procured
through the RFP, units were not included in this Area Plan Update, as instructed by CDA.
2 Minimum percentages of applicable funds are calculated on the annual Title IIIB baseline allocation, minus Title IIIB administration and minus
Ombudsman. At least one percent of the final Title IIIB calculation must be allocated for each “Priority Service” category or a waiver must be
requested for the Priority Service category(s) that the AAA does not intend to fund.
3 Legal Assistance must include all the following activities: Legal Advice, Representation, Assistance to the Ombudsman Program and
Involvement in the Private Bar.

Briefly describe the local governing board’s process to appoint Advisory Council
members:
Each new vacancy occurring on the Council is declared by Board Order. The Clerk of the Board’s
Office is then instructed to advertise each vacancy for a period of 20 days prior to the filling of
each seat to encourage and permit interested members of the public to apply. Vacancies are
identified on the County’s website. Member at Large applicants are interviewed by the Council’s
Membership Committee; Local Committee Seats are selected by the cities (usually the City
Councils). All new appointments to the Council are made by Board Order. New members are
given an orientation and advised of their duty to file FORM 700 and to complete ethics training for
public officials as required by the Fair Political Practices Commission. Members are also
provided video training on the Brown Act and the County’s own Better Governance Ordinance.
Expired terms are renewed by mutual agreement.

SECTION 18 - LEGAL ASSISTANCE PSA 7
2020-2024 Four-Year Area Planning Cycle
This section must be completed and submitted annually. The Older Americans Act
Reauthorization Act of 2016 designates legal assistance as a priority service under Title III B [42
USC §3026(a)(2)] 12 CDA developed California Statewide Guidelines for Legal Assistance
(Guidelines), which are to be used as best practices by CDA, AAAs and LSPs in the contracting
and monitoring processes for legal services, and located at:
https://aging.ca.gov/Providers_and_Partners/Legal_Services/#pp-gg
1. Specific to Legal Services, what is your AAA’s Mission Statement or Purpose Statement?
Statement must include Title IIIB requirements:
• For the provision of Legal Services, the AAA contracts with Contra Costa Senior Legal
Services (CCSLS). The mission is to ensure justice, dignity, health, security,
maximum autonomy and independence to older residents of Contra Costa, with a
particular emphasis on those with the greatest economic and social need. It provides
free legal advice, representation and education to elderly residents of Contra Costa
County. The most urgent objective is to resolve legal problems that are adversely
affecting basic needs of the elderly such as food, shelter, health care, and freedom
from physical, psychological or economic abuse.
2. Based on your local needs assessment, what percentage of Title IIIB funding is allocated to
Legal Services? Discuss:
• 11 % of adequate proportion of Title IIIB funding is directed to Legal Services.
3. Specific to Legal Services, has there been a change in your local needs in the past four
years? If so, please identify the change (include whether the change affected the level of
funding and the difference in funding levels in the past four years).
• Prior to the COVID-19 pandemic, there was a steady increase in clients seen (over 10%
increase in the four years pre-pandemic). Housing matters have increased.
Approximately 40% of cases are housing related, up from 27%, primarily landlord/tenant
disputes and eviction defense. Prior to the Omicron outbreak of the Coronavirus, the
most urgent trends concerned threats to housing and economic stability. These issues
are likely to become even more pronounced in the wake of the health crisis affecting our
community.
• With the closure of the senior centers, the legal services provider shifted to offering virtual
clinics telephonically or through videoconferencing. This has proven challenging, as
many clients do not have access to technology or the comfort level to use the online tools
to take up this opportunity. As a result, the provider is serving fewer seniors at clinics,
although the number of clients assisted directly remained stable. The pivot to remote
work resulted in added expenses (e.g. remote secure access to client database, ongoing
special cleaning, transcription of voice messages, increased support staff hours) that
may not be covered by the contract.
53
• The uncertainty and continued threat of the pandemic challenged the program this past
year. As cases started to decrease in the summer of 2021, Legal Services cautiously
and modestly re-opened services for in-person appointments, then a new surge hit in the
winter and forced the program to retreat back to remote work. Legal clinics at senior
centers halted once again. The pandemic resulted in increased expenses for the
organization, including higher cleaning costs, IT expenses to support remote work, salary
increases to stay competitive as an employer, etc. The provider worked diligently in
raising funds to cover these additional costs, including conducting a Spring Peer to Peer
Fundraiser, a Giving Tuesday Campaign, and a Year End Appeal. The provider also
increased their grant writing efforts to support the program.
4. Specific to Legal Services, does the AAA’s contract/agreement with the Legal Services
Provider(s) (LSPs) specify that the LSPs are expected to use the California Statewide
Guidelines in the provision of OAA legal services?
Yes, the agreement includes expectations to use the California Statewide Guidelines
in the provision of OAA legal services.
5. Does the AAA collaborate with the Legal Services Provider(s) to jointly establish specific
priorities issues for legal services? If so what are the top four (4) priority legal issues in
your PSA?
• Prevention of Elder Abuse
• Housing Preservation
• Access to Benefits
• Access to health care
6. Specific to Legal Services, does the AAA collaborate with the Legal Services Provider(s) to
jointly identify the target population? If so, what is the targeted senior population in your
PSA AND what mechanism is used for reaching the target population? Discuss:
Yes, the AAA collaborates with our legal service provider, CCSLS, to identify our target
population. The target population is older adults with the greatest social and economic
need. The mechanism for reaching them is through outreach and education at senior
centers, nutrition sites, senior housing complexes, community events, and gathering
places with diverse racial/ethnic populations, such as San Pablo and Bay Point. CCSLS
distributes brochures about its services in English, Spanish, and several Asian languages.
CCSLS recently began outreach at dialysis clinics to advertise free health care directive
services. CCSLS employs Spanish speaking staff and provides outreach to immigration
fairs. Website can be accessed in many different languages (via Google translate); use of
a language line for other languages (recently Farsi and Hindi).
Additionally, CCSLS collaborates with Ombudsman Services to reach those confined in
long-term care facilities.
7. Specific to Legal Services, what is the targeted senior population and mechanism for
reaching targeted groups in your PSA? Discuss:
54
The targeted senior population are those with the Greatest Social Need: isolated,
disabled, low-income, and limited-English speaking ability are all risk factors.
Social factors, including sexual orientation, rural status, racial and ethnic minority
background, and HIV/AIDS status are also prioritized. The Legal Services
Provider reaches them through a website that is accessible and includes a video
describing their services as well as a blog. It also relies on frequent in-person
outreach (over 35 events since the start of the pandemic through the end of 2021),
ongoing Google ads campaigns, distribute flyers in senior centers, food bank
distribution sites and to Meals on Wheel clients. In addition, it receives referrals
from Adult Protective Services, Family Justice Centers, Ombudsman Services,
Contra Costa Bar Assn., local Senior Centers, Information & Assistance, etc.
8. How many legal assistance service providers are in your PSA? Complete table below.
Fiscal Year # of Legal
Assistance
2020-2021 1
2021-2022 1
2022-2023 1
2023-2024 Leave Blank until 2023
9. Does your PSA have a hotline for legal services? Discuss:
There is no senior specific hotline. There was a statewide Senior Legal Hotline that was
funded by a Model Grant. It no longer exists, but Bay Area Legal Services does offer a
Help Line for eligible clients. With the support of trained volunteers, the Legal Services
Provider strives to answer calls as they come in during business hours.
10. What methods of outreach are Legal Services providers using? Discuss:
The Legal Services Provider conducts outreach through a website that is accessible
and includes a video describing its services. The provider also has a blog. The
Legal Service Provider relies on frequent in-person and virtual outreach (over 35
events since the pandemic started through the end of 2021), ongoing Google Ads
campaigns, flyer distribution in senior centers, food bank distribution sites, and
Meals on Wheel clients. In addition, referrals are received from Adult Protective

12. Discuss how older adults access Legal Services in your PSA: Discuss:
Older Adults can access the Legal Service provider at senior centers and at the agency’s
office in person or by telephone. It also conducts virtual and in-person clinics at senior
housing sites, assisted living facilities, and has staff who can travel to the home of an older
adult who is homebound and in need of urgent services.
13. Identify the major types of legal issues that are handled by the Title IIIB legal provider(s) in
your PSA. Discuss (please include new trends of legal problems in your area): Discuss:
The majority of cases handled by Contra Costa Senior Legal Services have to do with
eviction and other housing issues. Other issues include debtors’ rights and planning for
incapacity.
• Housing: The title III Legal provider assists seniors with problems relating to
housing, including assistance with publicly subsidized housing, eviction defense,
improving housing conditions, lockouts and utility shut offs.
• Elder Abuse: The title III Legal provider assists victims of abuse to enforce their
rights against their abusers. Services include advising seniors about financial
elder abuse, fraud and senior scams; assisting seniors in obtaining Elder Abuse
Restraining Orders; and, advising and assisting clients victimized by identity theft
or fraud.
• Consumer and Individual Rights: The Title III legal provider advises debtors about
their rights, assist with debt collector lawsuits, and with resolution of some
contract disputes. It also drafts powers of attorney and Advance Health Care
Directives.
• Public Benefits: The Title III legal advisor assists with waivers and
reconsiderations in SSI overpayment matters.
• It also engages in planning for incapacity (Advance Health Care Directives and
Durable Powers of Attorney) for older residents of the County
56
Prior to the recent outbreak of the coronavirus, the most urgent trends concerned threats to
housing and economic stability. These issues are likely to become even more pronounced
in light of the health crisis affecting our community.
14. In the past four years, has there been a change in the types of legal issues handled by the
Title IIIBlegal provider(s) in your PSA? Discuss:
The legal provider is now able to handle a limited number of Social Security, SSI and
Medi-Cal matters as well as expanding services for incapacity planning thanks to the pro
bono volunteers.
15. What are the barriers to accessing legal assistance in your PSA? Include proposed
strategies for overcoming such barriers. Discuss:
The Legal Services Provider is small and has a limited ability to conduct outreach in
languages other than Spanish and English. The Legal Services Provider is launching a
survey to better understand awareness of services based on language and other
demographics to improve its outreach efforts. It is also endeavoring to use volunteers to
address this barrier. Seniors also have difficulty with transportation. While services are
offered by telephone, many legal issues require review of documents or in person
assessment of capacity. The legal services provider is collaborating with other agencies
such as the Family Justice Center to provide services in the western and eastern portions
of the county.
16. What other organizations or groups does your legal service provider coordinate services
with? Discuss:
The Legal Service Provider coordinates services with Adult Protective Services, Family
Justice Centers, Ombudsman Services, Contra Costa Bar Association, local Senior
Centers, Information & Assistance, Meals on Wheels Diablo Region, etc. In addition, it
collaborates on many projects including the Elder Abuse Prevention Project and Abuse
in Later Life Program (multiple agencies), East County Senior Resource Initiative (Meals
on Wheels & others), the Resident Empowerment Program (Empowered Aging), and
Pop up Legal Clinics (the Food Bank), etc.

RECOMMENDATION(S):
APPROVE and AUTHORIZE the Purchasing Agent, on behalf of the Health Services Director, to execute a Purchase Order with Arthrex, Inc in
an amount not to exceed $900,000 to procure instruments, implants, and supplies for the orthopedic department for the period from April 1,
2022, through January 31, 2024.
FISCAL IMPACT:
This purchase order will result in expenditures of up to $900,000 and will be funded 100% by Hospital Enterprise Fund I revenues.
BACKGROUND:
Arthrex, Inc. is a global medical device company and leader in new product development and medical education in orthopedics. Arthrex
provides instruments, implants, supplies and biologics that are necessary for arthroscopic surgeries for better outcomes for our patients. There
are currently no other products on the market that can achieve the same surgical outcomes in the same amount of time and the same patient and
surgeon satisfaction. By having a lower footprint, and an ease of use, surgery times are shortened, patients’ recovery times are shortened, and
the risk of infections are decreased.
CONSEQUENCE OF NEGATIVE ACTION:
If this purchase order request is not approved, Contra Costa Regional Medical Center (CCRMC) will not be able to provide the surgical needs
of the general population of Contra Costa County. This can lead to delays or cancellation of surgeries, and lead to detrimental outcomes for our
patients.

RECOMMENDATION(S):
1. ADOPT Resolution No. 2022/137, initiating proceedings for the formation of a new zone, Zone 2608, within County Service Area P-6, in the
Unincorporated Martinez area of the County.
2. FIX a public hearing for May 24, 2022, at 9:00 a.m., on the formation of Zone 2608 within County Service Area P-6.
3. FIX a public hearing for May 24, 2022, at 9:00 a.m., to consider the adoption of Ordinance 2022-15, which would authorize the levy of a
special tax to augment funding for police protection services in proposed Zone 2608, and to authorize submission of the ordinance to the voters
for approval at the July 26, 2022, election.
FISCAL IMPACT:
The cost of establishing the proposed Police Services Special Tax District is paid for by the developer of the subdivision.
BACKGROUND:
Pursuant to the conditions of approval for Subdivision 9545 (County File #SD20-9545), the developer of the property located at 197 Midhill
Road in the Martinez area is required to establish a Special Police Services Tax District for the 38-lot subdivision prior to recording the final
map for the subdivision. The proposed special tax district would fund an increase in the level of police protection services that is provided in the
unincorporated Martinez area.
Adoption of a resolution of intent to form a new tax district (Resolution No. 2022/137) is required by Government Code Section 25217,
subdivision (b), as the first step in forming the proposed zone, which will serve as the vehicle to collect special taxes within the proposed zone if
the tax measure is approved by the voters on the July 26, 2022, ballot. The resolution includes information regarding the name and boundaries
of the zone, the different level of services to be provided, and the method by which the increased level of service is to be funded. The resolution
also directs the Clerk of the Board to publish and mail notice of a public hearing regarding the proposed zone formation. It is recommended that
the Board set this hearing for 9:00 a.m. on May 24, 2022. If at the conclusion of that public hearing the Board determines that more than 50%

proposed police service district currently consists of a single 9.92-acre property owned by the Brent and Kathleen Echols, who per the
conditions of approval for the subdivision are required to establish the police service district prior to recording the final map.
If there is no majority protest and the Board elects to proceed with the formation of the zone, a second public hearing would be required to
consider the approval of Ordinance No. 2022-15, pertaining to the proposed levy of a special tax on the subject parcel within Zone 2608 for
police protection services and submission of the measure to the voters, pursuant to Government Code Section 50077, subdivision (a). It is
recommended that this hearing be set at 9:00 a.m. on May 24, 2022, immediately following the hearing on the zone formation. If the Board
thereafter adopts Ordinance No. 2022-15, then the tax measure would be submitted for placement on the July 26, 2022, ballot.
CONSEQUENCE OF NEGATIVE ACTION:
If not approved, Ordinance No. 2022-15 will not be adopted, formation of Special Tax Zone 2608 will not occur, and the Special Tax
District will not be established at the May 24, 2022, hearing.

RESOLUTION OF INTENTION TO FORM ZONE 2608 OF COUNTY SERVICE AREA P-6 IN THE UNINCORPORATED
MARTINEZ AREA
The Board of Supervisors of Contra Costa County RESOLVES:
1. The Board of Supervisors of Contra Costa County proposes the formation of new zone in the unincorporated Martinez area of
County Service Area (CSA) P-6, pursuant to Article 8 of Chapter 2.3 of Part 2 of Division 2 of Title 3 of the California
Government Code.
2. The boundaries of the territory to be included in the zone area are described in 'Exhibit A' and shown in 'Exhibit B', both of
which are attached hereto and incorporated herein by this reference.
3. The formation of Zone 2608 is proposed to provide the County of Contra Costa with a method of financing an increased level
of police protection services to the area within the zone.
4. The proposed zone would provide a level of police protection services that exceeds the level of service outside the zone, and if
approved by the voters, the proposed zone would generate additional revenue in the form of special taxes to fund the increase in
this level of service.
5. The increase in the level of service would be financed through the levy of a voter-approved special tax on all taxable parcels
within the zone.
6. The name proposed for the zone is "Zone 2608" of CSA P-6.
NOW, THEREFORE, BE IT RESOLVED THAT at 9:00 a.m. on May 24, 2022, in the Chamber of the Board of Supervisors,
County Administration Building, 1025 Escobar Street, Martinez, CA 94553, this Board will conduct a public hearing upon the
proposed formation of Zone 2608 of CSA P-6. The Clerk of the Board is hereby directed to give notice of the public hearing by
(1) publishing a notice that complies with Government Code Section 25217, subdivision (d)(1), pursuant to Government Code
Section 6061; (2) mailing the notice to all owners of property within the proposed zone; (3) mailing the notice to each city and
special district that contains, or whose sphere of influence contains the proposed zone; and (4) verifying that the notice is posted
in at least three public places within the territory of the proposed zone.

Subject:Memorandum of Agreement Amendment #28-975-2 with City of Brentwood
RECOMMENDATION(S):
APPROVE recommendations from the Fish and Wildlife Committee (FWC) for the allocation of 2022 Fish and Wildlife Propagation funding
for ten projects totaling $50,325.
FISCAL IMPACT:
The recommendation will have no impact on the County General Fund. The FWC is proposing to allocate $50,325 or about 35% of the
$145,874 propagation funds available as of January 12, 2022. Fish and wildlife propagation funds are restricted to costs for the protection,
conservation, propagation, and preservation of fish and wildlife, pursuant to Fish and Game Code section 13100, and are budgeted in the Fish
and Game Fund (110200).
BACKGROUND:
On November 22, 2010, the IOC received a status report from Department of Conservation and Development (DCD) regarding the allocation
of propagation funds by the Fish and Wildlife Committee (FWC). The IOC accepted the report along with the recommended modifications to
improve the grant process in the future. The modifications included (1) updating the FWC Conflict of Interest Code, which was accomplished,
and; (2) having the IOC conduct a preliminary review of annual FWC grant recommendations prior to Board of Supervisors review, which has
since been a standing referral to the IOC.
Attached is a memo describing the outreach and selection process and criteria, and transmitting the grant funding recommendations of the
County's Fish & Wildlife Committee for full or partial funding of ten projects. The Fish & Wildlife Committee exercised care in limiting
allocations to the direct costs of each project for activities that protect, conserve, propagate, and preserve fish and wildlife. The grant matrix
attached to the transmittal shows each project in summary form, including the amount requested vs. the proposed allocation, the rationale for the
FWC's decision, and any limitations on the use of the funds.
The recommendations would allocate only 35% of the current fund balance in an effort to conserve a balance for future years. As shown on the
next page, annual receipts have declined during the last three fiscal years.

The IOC, at its regular meeting on April 11, 2022, considered the FWC recommendations. A member of the public commented at the IOC
meeting that a Bay Area city was grappling with a geese overpopulation problem and wondered if Contra Costa County had such a problem
that could be addressed with these funds. IOC Vice Chair Andersen identified that the city in question is Santa Clara. She noted that geese
have sometimes been a problem in some south Contra Costa communities and that a program called "Goosebusters" has served to
successfully relocate geese within fish and game guidelines. Staff clarified that such an activity would likely fall under the permitted uses
of restricted fish and game funds, should such application for them be made.
The IOC recommends approval of the FWC recommendations for funding.

SUBJECT: Grant Funding Recommendations from the Contra Costa County Fish and
Wildlife Committee
The Contra Costa County Fish and Wildlife Committee (FWC) has completed its review of grant requests
for funding from the Fish and Wildlife Propagation Fund (Fund) and is forwarding its grant award
recommendations to the Internal Operations Committee (IO). The FWC reviewed 16 grant applications and
recommends 10 of them for full or partial funding. The FWC is requesting that the IO Committee consider
these recommendations and make their own recommendation for consideration by the full Board of
Supervisors (Board). This memo provides background on the grant program, explains the review process
performed by the FWC and documents the FWC’s recommendations on grant funding.
I. Background
Fish and Wildlife Propagation Fund
The Fish and Wildlife Propagation Fund was established in accordance with the California Fish and Game
Code (Code) 13100 as a repository for fines collected for certain violations of the Code and other
regulations related to fish and game. The most common fines are small ($25-$150) and are processed
through the four Superior Courts in Contra Costa County. The fines typically stem from hunting or fishing
violations (e.g. not possessing a valid license) and illegal dumping. Occasionally there are larger fines that
result from violations, including failure to obtain appropriate permits for activities such as streambed
alteration or illegal take of a special status species. A portion of the fines are deposited into the Fish and
Wildlife Propagation Fund. As of January 12, 2022, the Fund had an available balance of $146,925.30.
Page 2 of 4
FWC Grant Program
The Board has charged the FWC with coordinating a process by which fine money could be appropriately
“expended for the protection, conservation, propagation, and preservation of fish and wildlife” [Fish and
Game Code 13100]. Since 1996, the FWC has implemented a structured process for reviewing funding
requests. The FWC developed a grant application packet (attached), which includes a cover letter to
explain the grant process and funding priorities, an application to solicit relevant information about the
project, and a copy of the expenditure criteria established by California law for the Fish and Wildlife
Propagation Fund.
Public Outreach to Advertise the Grant Program
In October 2021, the application packet was sent to the Fish and Wildlife Committee mailing list,
Contra Costa Watershed Forum mailing list, and to teachers and programs that could benefit from the
grant program including Contra Costa College, Diablo Valley College, Los Medanos College, UC
Berkeley, Cal State University - East Bay, University of California Agriculture and Natural Resources,
Mills College and St. Mary’s College. The CCC Office of Communications and Media distributed a
press release to local and regional media outlets regarding the availability of the grant application
packet. CCTV publicized it on the CountyNet Bulletin Board which reaches 400,000+ homes in the
County. It was also made available on the Committee’s website and to anyone who requested a copy.
FWC Grant Review Process in 2022
16 applications requesting a total of $145,873.79 were reviewed.
The Fish and Wildlife Committee members considered the funding of the applications at their January and
February meetings. Some applicants attended FWC meetings to make themselves available to answer
questions regarding their applications.
II. Recommendation of Funding on Grants for 2022
At its February 16, 2022 meeting, the FWC recommended full or partial funding for 10 of the proposed
projects. Projects recommended for funding total $50,324.27 and are geographically located across the
County. More details are provided on the attached grant recommendations chart, which provides
information on all of the applications. The specific FWC recommendations and vote are listed on Pages 2
– 4 of this memo. Members in attendance and voting on these items were: Nicole Balbas (At-large),
Clark Dawson (District III), Roni Gehlke (At-large), Susan Heckly (District II), Kathleen Jennings (At-
large), Brett Morris (District IV), Daniel Pellegrini (District V), and Cass Rogers (At-large).
The following recommendations are for full funding of the project as proposed unless noted otherwise.
FWC Recommendations:
1) Appropriate $6,455.00 to Friends of Orinda Creek for their “San Pablo Creek Restoration Project:
Phase I” project. The project will restore a degraded section of San Pablo Creek that runs through
the downtown area of Orinda. Partial funding is recommended and will be used for boulders and
fill for step pools and native plants for revegetation (recommendation is to reduce native plant
funding from $2,000 to $1,455).
2) Purchase a drone and manual telephoto zoom lens for a Canon DSLR camera for the California
Department of Fish and Wildlife (CDFW) in the amount of $998.70 to be used in a study that will

assist in the inventory of potential roost sites for bat species throughout the County and provide
insight into the ecological importance of specific bridges or locations for bats.
3) Appropriate $1,050.00 to Worth a Dam for their “Beaver Festival XIII: The Case of the Missing
Salmon” project. Children will be ‘nature detectives’ and solve a mystery at a beaver pond,
learning to identify the habits and tracks of various riparian wildlife. Funds will be used for cards,
envelopes, magnifying glasses, exhibit location map festival brochures, artist pastels, children's
pastels, printing of signs and quizzes given to the children after they complete the activity.
4) Appropriate $3,390.00 to SPAWNERS for their “Communities for Creeks” project. The project is
mid-length feature documentary and accompanying curriculum guide for students grades 7 – 12
that will educate them about watershed ecology, human impact on watersheds, and scientific
principles of fish and wildlife conservation. Partial funding is recommended for documentary
production and post-production items, and curriculum materials; and may not be used for drone
operator, rental insurance, sound mix, music licensing, festival entry fees and educational fee.
5) Appropriate $7,669.87 to Contra Costa Resource Conservation District (CCRCD) for their “Zero-
Emissions Habitat Restoration Tools” project. The purchase of battery-powered tools will allow
CCRCD to reduce air and noise pollution from necessary tool use and increase the EcoStewards
Program's capacity to benefit wildlife through habitat restoration. Partial funding is recommended
and may be used for battery trimmers, backpack batteries, battery hedge trimmer, batteries and
chargers; and may not be used on a shipping container or railroad ties.
6) Appropriate $2,692.70 to Contra Costa Resource Conservation District for their “Improving and
developing the Contra Costa Resource Conservation District's Richmond Greenway adopted spot.”
project. The project will improve CCRCD's adopted spot on the Richmond Greenway through the
implementation of an irrigation system, planting of native vegetation, and putting up an educational
sign. Funds will be used for irrigation material and equipment, native plants, cement and signage
materials.
7) Appropriate $2,400.00 to Friends of Alhambra Creek for their “Martinez Educational Mural
Featuring Local Flora and Fauna” project. The mural will offer a free and accessible outdoor
educational opportunity for people of all ages, serve as a destination for local school field trips and
as a site for teachers to encourage children to visit and interact with to earn extra credit. Partial
funding is recommended for paint, various supplies, protectant coating, prep work and final
coating; and may not be used for insurance, design fee, mural painting fee or CCRCD fiscal
sponsor fee.
8) Appropriate $9,949.00 to Friends of San Ramon Creek for their “Arundo Removal and
Replacement in San Ramon Creek subwatershed” project. The project will remove Arundo from
the creek bank and replanting the area with native plants which will provide a healthier, more
biodiverse habitat for the fish living in the water and the wildlife that utilize the riparian area.
Partial funding is recommended for tools, supplies, rental equipment, and plants; and may not be
used for RCD handling cost or the water quality measuring items.
9) Appropriate $6,249.00 to Lindsay Wildlife Experience for their “Native California Aquatic
Ecosystems Exhibit and Educational Programs” project. The project will upgrade the Creekwall
section of the museum's exhibit floor into an engaging and interactive exhibit which will provide
associated programming. Partial funding is recommended and may be used for interpretive signage
with infographics, and interactive rail; signage and backdrop for: tiger salamander, western pond
turtle, rattlesnake and garter snake enclosures; and may not be used for the environmental wall
mural or installation.
10) Appropriate $9,470.00 to Mt. View Sanitary District for their “Moorhen Marsh and the MVSD
Wetlands Education Program” project. The project will reduce nutrient pollution through the
sustainment of native vegetation and the floating island system within Moorhen Marsh, which
hosts the MVSD Wetlands Education Program. Partial funding is recommended for wetlands

student booklets (recommendation is to reduce from $7,000 to $3,000), pencils, field trip supplies,
native plants for floating islands, worm casting, soil, coir, myselia, and planting equipment; and
may not be used on stickers.
11) Further, the FWC also recommended that within a year of grant funding approval, or within one
month of project completion, whichever comes sooner, recipients must submit a final project report
which includes invoices and receipts documenting how funds were spent and the results of the
project. Details will be outlined in the grant award packet provided to all successful applicants.

funding this year because the intern
position was primarily to assist the
Conservation chair and other Board
members.

Dear Fish and Wildlife Propagation Fund Grant Applicants:
The Contra Costa County Fish and Wildlife Committee is pleased to announce that completed funding applications are
now being accepted for consideration for the Contra Costa County Fish and Wildlife Propagation Fund (Fund). All
application materials and guidelines are attached. Proposals must be received by 5:00 p.m. on Wednesday, January 5, 2022
(a postmark of January 5, 2022, does not satisfy the submission deadline). Proposals may be emailed or mailed. Any
applications that are received after the due date or without a signature will not be considered. Staff will acknowledge
receipt of each grant application. If you do not receive a confirmation of receipt contact Maureen Parkes at 925-655-2909
prior to the deadline. The recommendations of the Fish and Wildlife Committee will be forwarded to the Contra Costa
County Board of Supervisors, which maintains final decision-making authority for expenditures from the Fund.
The Contra Costa County Fish and Wildlife Propagation Fund is entirely supported by fine revenues resulting from
violations of the Fish and Game Code and Title 14 of the California Code of Regulations in Contra Costa County
(County). Projects awarded from the Fund must benefit the fish and wildlife resources of the County and must meet the
requirements of Section 13103 of the Fish and Game Code (attached). If your project is eligible under Section 13103 (d),
(h), (i), or (m) please send a copy of your draft proposal to Maureen Parkes at maureen.parkes@dcd.cccounty.us by
November 4, 2021. Staff will coordinate with the California Department of Fish and Wildlife to confirm the project’s
eligibility to receive funds. See Instructions for more details. All applications that satisfy the requirements listed in the
funding application instructions will be considered.
The Fish and Wildlife Committee strongly encourages applications related to:
improving habitat
scientific research
public education
threatened and endangered species
resolving human/wildlife interaction issues
In addition to the above areas of interest, the Fish and Wildlife Committee wishes to fund one or more projects that
increase collaboration with law enforcement agencies and community cultural organizations on enforcement issues and
education focusing on communities that may be unaware of local fish and game laws. Projects that provide multilingual
signage and educational materials are encouraged.
The Fish and Wildlife Committee considers grant awards for prospective expenditures from non-profit organizations,
schools, and government agencies. The Committee generally does not recommend funding for operating costs and
overhead, such as staff salaries, benefits, or utilities. The Committee generally gives preference to funding material
expenses (e.g. purchase of equipment and materials). Organizations, schools, and government agencies that have received
previous Fish and Wildlife Propagation Fund grants should have a positive track record of completing projects and
submitting final reports in an efficient, timely and clear manner.

The Committee expects to recommend awards to several applicants. However, it is possible that a particularly excellent
proposal will be recommended to receive a large portion of the total available funds. During the 2021 grant cycle a total
of $60,830.71 was awarded to seven projects. The awards ranged from $4,973.00 to $16,000.00. Available funds vary
from year to year and the Fish and Wildlife Committee cannot commit to multi-year or recurring funding. The Board of
Supervisors will make the final decision on the grant awards and successful applicants may anticipate receiving
notification by May 2022. Project expenditures eligible for reimbursement must be made subsequent to Board of
Supervisors approval of grant funding.
The grant award funds will be disbursed on a cost reimbursement basis.* (See below for exceptions.) Within a year
of grant funding approval, or within one month of project completion, whichever comes sooner, recipients must submit
a final project report which includes invoices and receipts documenting how funds were spent and the results of the
project. Any expenses not listed on the original grant application should be requested ahead of time. Unapproved
expenses may not be reimbursable. Fish and Wildlife Propagation fund grants will be disbursed after receipt and approval
of the final project report. Details will be outlined in the grant award letter that is sent to all successful applicants.
*Exception For Non-Profit Organizations That Can Demonstrate Financial Hardship: Private, non-profit entities
that can demonstrate that providing Fish and Wildlife Propagation grant funding on a cost reimbursement basis will
create a financial hardship and be detrimental to the operation of the program will be eligible to receive up to ½ of the
grant amount after the grant is awarded. The remaining amount of the grant will be disbursed after the entity has
submitted information including invoices and receipts documenting how the initial disbursement was spent. Within a year
of initial notification of the grant funding award (May 2023), or within one month of project completion, whichever
comes sooner, the entity will be required to submit information including invoices and receipts documenting how the
second disbursement was spent, and provide a final project report documenting the results of the project.
*Exception For Small Projects Under $1,000: Grant funding may be disbursed to private, non-profit entities prior to
the beginning of the project if the award is under $1,000 and the entity has provided documentation that the project
could only be initiated with advance funding. Within a year of grant funding, or within one month of project completion,
whichever comes sooner, recipients must submit a final project report which includes invoices and receipts documenting
how funds were spent and the results of the project.
The Committee appreciates your interest in this opportunity to improve the fish and wildlife resources in Contra Costa
County. Should you have any questions about the Fish and Wildlife Committee or this funding program, please contact
me at 925-655-2909 or maureen.parkes@dcd.cccounty.us.
Sincerely,
Maureen Parkes

$100,000 or less; and (3) professional/personal service contracts of $100,000 or less.
The objective of the program is to award at least 50% or more of the total eligible dollar base amounts to SBEs. A Small Business Enterprise, as
defined by the California Government Code, Section 14837, Chapter 3.5 must be:
Independently owned and operated business, which is not dominant in its field of operation;
The principal office of which is located in California, the officers of which are domiciled in California, and which together with
affiliates, has 100 or fewer employees;

Subject:Small Business Enterprise, Outreach, and Local Program Report for the Period July through December 2021
BACKGROUND: (CONT'D)
Reporting Requirements
It is the responsibility of each County department to track and compile the data for purchasing activities in order to provide a countywide report
to the Board of Supervisors.
The Internal Operations Committee has responsibility for evaluating the semi-annual reports and making recommendations to the Board on
program policies and reporting. The Board receives reports in six-month increments, with the last report submitted to the Board for the period
ending June 2021. Attachment A constitutes the report due for the period of July 1 – December 31, 2021.
Summary Findings
The following table summarizes the attached department activity on a countywide basis.

Construction Contracts 3 3 100%$150,000 $150,000 100%
While the County did not achieve the 50% goal, this information shows the County directed more than $12.8 million in qualifying transactions
to SBE firms during the six-month reporting period, achieving a 46.4% award rate for professional/personal services transactions and a 21.2%
award rate for purchasing transactions. There were 3 construction contracts reported in this period.
It is worth noting that the SBE participation goals of surrounding agencies are typically in the 20-25% range. By that measure, Contra Costa
County’s reported activity is above that threshold for professional/personal services, and within the range for purchasing transactions. The
following departments are to be commended for achieving 50% or more program compliance this reporting period:
Professional/Personal Services: Animal Services, Clerk of the Board, Fire Protection District, and Public Works
Purchases: Agriculture, Clerk of the Board, Communications Media, County Counsel, and Treasurer – Tax Collector
Of particular note, Clerk of the Board, and the Fire Protection District are to be commended for achieving a 100% award rate for qualifying
professional services contracts. Clerk of the Board is also commended for achieving a 100% award rate for qualifying purchasing transactions.
Public Works is commended for achieving a 100% award rate for construction contracts.

E-Outreach Report
In order to encourage the use of small, local, and disadvantaged businesses, the County's E-Outreach Program requires bids and Request for
Proposals greater than $10,000 to be solicited online. For this period, there were 34 bids totaling $20,072,078 that fell within the parameters of
the program.
The data specific to electronic solicitations is developed and provided by the Purchasing Division of the Public Works Department, and reflects
outreach to small, women-owned, minority-owned, local, disabled veteran-owned, and disadvantaged business enterprises. During this reporting
period, 34 bids were conducted using the BidSync e-outreach site. Notifications were sent to 267,328 businesses, of which 31.6% are considered
small, local, or disadvantaged business enterprises.

Conclusion
The County has demonstrated continued commitment to achieving the 50% goal for participation by SBE firms in contract and purchasing
activities. While the data for some departments is below this threshold, departments are showing some interest in increasing the percentage of
awarded contracts. Instruction is being provided on the search features of the purchasing system, to assist in identifying businesses in the small,
local, women, minority, veteran and disadvantaged business categories.
RECOMMENDATION(S):
APPROVE and AUTHORIZE the Auditor-Controller, to pay up to $135,432 to Agiliti Health, Inc. for the rental of medical devices and
equipment provided to Contra Costa Regional Medical Center (CCRMC), for the period of October 1, 2021 through December 31, 2021.
FISCAL IMPACT:
Approval of this action would result in a one-time expenditure not to exceed $135,432 and will be funded by American Rescue Plan Act
(ARPA) revenues.
BACKGROUND:
CCRMC has rented hospital beds, infusion pumps, and other medical equipment and devices from Agiliti Health, Inc. since 2007. They have
provided competitive pricing through the Vizient Group Purchasing Organization (GPO) Contracts. Agiliti Health Inc. has demonstrated their
reliability for providing fast, on-site medical equipment deliveries, which has minimized disruptions to the delivery of patient care, leading to
better clinical outcomes for our patients.
As a direct result of treating COVID patients, the hospital experienced higher acuity levels and an increased length of stay. The Sterile
Processing Department (SPD) did not anticipate the higher demand for equipment and specialty bed rentals and had exhausted their budget. To
avoid this situation from occurring again, SPD has a resource in place that is accountable for monitoring the budget to ensure the department
stays on target or proactively provides the business case when additional funding is required.
Due to the aforementioned increased number of patients and budget exhaustion, the vendor was not paid by CCRMC for supplies provided in
good faith for the period of October 1, 2021 through December 31, 2021. Therefore, CCRMC has determined that Agiliti Health, Inc. is entitled
to payment for the value of the supplies provided under the equitable relief theory of quantum meruit. The theory provides that where a vendor
has been asked to provide products or services without a valid purchase order, and the vendor does so to the benefit of the recipient, the vendor is
entitled to recover the reasonable value of those products or services.
CONSEQUENCE OF NEGATIVE ACTION:
If this request is not approved, CCRMC will be unable to pay Agiliti Health, Inc. for services provided in good faith, and clinicians will no
longer be able to place physician orders for equipment essential to the patient’s treatment plan, placing the patient’s health and safety at risk.

RECOMMENDATION(S):
APPROVE and AUTHORIZE the Conservation and Development Director, or designee, to execute an amendment to extend a tolling agreement
with Discovery Builders, Inc., West Coast Home Builders, Inc., and the East Contra Costa Fire Protection District to toll the limitations period
for potential litigation related to fire protection facilities fees through December 31, 2022.
FISCAL IMPACT:
None.
BACKGROUND:
On November 3, 2020, the Board of Supervisors adopted Ordinance No. 2020-27, an ordinance that establishes fire protection facilities fees for
that portion of the county that is located within the boundaries of the East Contra Costa Fire Protection District. The ordinance authorizes the
County to impose the fees and authorizes the Fire District to collect, retain, and expend the fees. Fee amounts are specified in the ordinance and
must be paid before a building permit is issued for new residential or commercial construction. At the same meeting, the Board also approved a
fee administration agreement between the County and the Fire District that establishes the terms and conditions for the Fire District to collect,
retain, and expend the fees. Under the fee administration agreement, the Fire District is required to indemnify the County against all lawsuits
related to the fees and the fee ordinance, including any challenge to the validity of the fees, any challenge to the Fire District’s use of the fees,
and any challenge related to compliance with the Mitigation Fee Act.
The Fire District, Discovery Builders, Inc., and West Coast Home Builders, Inc., are currently in a dispute over the fee amounts in the ordinance.
These parties are engaged in discussions to try to resolve their differences without incurring the cost and expense of litigation. At the request of
the parties, the County previously entered into a tolling agreement to toll (suspend) the statutory limitations period for filing a lawsuit related to
fire protection facilities fees from February 24, 2021, through April 30, 2021. The parties and the County subsequently agreed to amend the
tolling agreement to extend the tolling period through April 30, 2022. The parties have since requested that the County agree to amend the
tolling agreement again to extend the tolling period through December 31, 2022.
CONSEQUENCE OF NEGATIVE ACTION:
The tolling agreement between the County and the parties would not be extended and would terminate after April 30, 2022.

SECOND AMENDMENT TO TOLLING AGREEMENT
This Second Amendment to Tolling Agreement (“Second Amendment”) is entered into
by and between Discovery Builders, Inc. (“Discovery”) and West Coast Home Builders, Inc.
(“WCHB”), on the one hand, and the County of Contra Costa and the Contra Costa County
Board of Supervisors (collectively “County”), and the East Contra Costa Fire Protection District
and Board of Directors of the East Contra Costa Fire Protection District (collectively “Fire
District”), on the other hand. Discovery, WCHB, County and Fire District will sometimes be
collectively referred to herein as “Parties” and individually as “Party.”
WHEREAS, on February 24 and 25, 2021, the Parties entered into a Tolling Agreement
(“Tolling Agreement”) relating to claims arising from actions taken by the Contra Costa County
Board of Supervisors during its November 3, 2020 meeting, wherein the Contra Costa County
Board of Supervisors held a public hearing, concurred with findings in a Fire District Notice of
Findings Report, and adopted Ordinance No. 2020-27, an ordinance that establishes fire facility
development impact fees for that portion of the County that is located within the boundaries of
the Fire District, and authorizes the County to impose the fees and the Fire District to collect,
retain, and expend the fees.
WHEREAS, on or about April 30, 2021 to May 4, 2021, the Parties entered into an
Amendment to Tolling Agreement (“First Amendment”) wherein the Parties amended Paragraph
1 of the Tolling Agreement to change the Tolling Period therein to read “from February 24, 2021
through and including April 30, 2022.
WHEREAS, on September 14, 2021 and on September 16, 2021, the Contra Costa
County Fire Protection District (“Con Fire”) and the Fire District, respectively, adopted
substantially similar resolutions (Con Fire Resolution No. 2021/8 [as amended by Con Fire
Resolution No. 2022/3] and Fire District Resolution No. 2021-32) to annex the Fire District to
Con Fire, dissolve the Fire District and name Con Fire as successor agency pursuant to the
Cortese-Knox-Hertzberg Local Government Reorganization Act of 2000, Government Code
Section 56000, et seq. Pursuant to Con Fire Resolution No. 2021/8, as amended by Resolution
No. 2022/3, Con Fire confirmed that certain categories of contracts, including the Tolling
Agreement and all amendments thereto, entered into by the Fire District would, upon annexation,
be transferred to Con Fire as the successor to the Fire District.
WHEREAS, on March 9, 2022, the Contra Costa Local Agency Formation Commission
adopted Resolution No. 21-11 approving the annexation of the Fire District to Con Fire and the
dissolution of the Fire District, effective June 30, 2022.
WHEREAS, the Parties wish to confirm that, since the Tolling Period contained in this
Tolling Agreement extends beyond the June 30, 2022 date on which the Fire District is dissolved
and on which Con Fire becomes the Fire District’s successor, Con Fire will succeed to and
become bound by the obligations of the Fire District in this Tolling Agreement.
WHEREAS, the Tolling Agreement and First Amendment were entered into in
recognition that it would be productive for some or all of the Parties to engage in discussions to
2
try to resolve their differences without having to simultaneously incur the cost and expense of
litigation while these discussions occurred.
WHEREAS, the Parties have continued to make progress in their discussions and believe
that they may be able to avoid litigation by amending the Tolling Agreement to extend the
Tolling Period.
WHEREAS, the Parties wish to enter into this Second Amendment to toll the applicable
statutes of limitations and other time-related rules, doctrines, claims or defenses identified in the
Tolling Agreement for an additional period of time.
NOW, THEREFORE, to minimize the cost and expense of potentially avoidable
litigation, and in consideration of the mutual promises, representations, terms and conditions
contained herein, and of other good and valuable consideration, the reasonableness and
sufficiency of which the Parties hereby acknowledge, the Parties agree as follows:
1. The Parties hereby amend Paragraph 1 of the Tolling Agreement to change the
Tolling Period therein to hereinafter read: “from February 24, 2021 through and including
December 31, 2022 (“Tolling Period”).”
2. The Parties hereby add a new paragraph 9 to the Tolling Agreement that states as
follows:
“The Parties acknowledge that the Fire District is dissolving on June 30, 2022 and
that the Tolling Period extends beyond that date. The Parties hereby confirm their
understanding that the Contra Costa County Fire Protection District (“Con Fire”)
will become the successor agency of the Fire District as of that date and, in that
capacity, Con Fire will succeed to all of the rights and obligations of the Fire
District, including the Fire District’s agreement herein to the Tolling Period set
forth in Paragraph 1 of the Tolling Agreement.”
3. All other terms, conditions and provisions of the Tolling Agreement, as amended
by the First Amendment, shall remain the same.
