Agenda packet — American Canyon City Council, April 15, 2025 (part 4 of 6)

as the Napa River Bay Trail, Napa County Parks and Open Space District, and Wetlands Edge Park. At this time, specifics on the routes of active transportation facilities such as trails through open spaces are not defined. The creation of any active transportation facilities would be subject to environmental review separate of the Draft EIR. No revisions to the Draft EIR are necessary in response to this comment.

Response 9-6
The commenter requests the language in the Napa Valley Transportation Authority discussion on page 4.5-14 is revised to replace “county transportation plan” with “countywide transportation plan”.

In response to this comment, the following revision has been made to the Draft EIR Sub-Section 4.5.2, Regulatory Setting, in Section 4.5, Greenhouse Gas Emissions. The revision would not alter the impact analysis or findings of the Draft EIR and, as such, would not warrant recirculation of the Draft EIR.

NVTA also develops the long-range countywide transportation plan, which (along with similar plans from the other eight Bay Area counties) forms the “primary basis” for the RTP/SCS adopted by the Metropolitan Transportation Commission. In turn, the countywide transportation plan must consider the most recently adopted RTP/SCS to assure that both plans employ a common planning framework.

Response 9-7
The commenter requests the language in the leading paragraph on page 4.6-4 is revised to state “would allow the region” to “would support regional efforts”. The commenter requests a discussion of the regional transportation plan/sustainable communities strategy is updated to reflect Plan Bay Area 2050+.

CEQA Guidelines 15125(a) state, generally, a lead agency should describe physical environmental conditions as they exist at the time the notice of preparation if published. The notice of preparation for the Draft EIR was released in July 2022 for public review. As of March 2025, Plan Bay Area 2050+ has not yet been adopted by the Association of Bay Area Governments and therefore did not represent baseline conditions used for evaluation of environmental impacts within the Draft EIR. No revisions to the Draft EIR are necessary in response to this comment.

In response to the commenter’s request regarding language revisions, the following revision has been made to the Draft EIR Sub-Section 4.6.2, Regulatory Setting, in Section 4.6, Land Use and Planning. The revision would not alter the impact analysis or findings of the Draft EIR and, as such, would not warrant recirculation of the Draft EIR.

Each of the regions must prepare a Sustainable Communities Strategy (SCS), as an integral part of its regional transportation plan, that contains land use, housing, and transportation strategies that, if implemented, would allow the region support regional efforts to meet CARB’s targets.

Response 9-8
The commenter requests that on Page 4.7-19 Program C as well as prior references to Policy MOB1.20 is updated in the General Plan to reflect City coordination with Napa Valley Transportation Authority in developing a locally-adopted Active Transportation Plan.

This comment pertains to the preparation of the 2040 General Plan Update but does not pertain directly to the Draft EIR. No revisions to the Draft EIR are necessary in response to this comment.

Response 9-9
The commenter requests the distances in the last paragraph on page 4.11-1 are updated to reflect updated methodologies provided from Napa Valley Transportation Authority in January 2025. In addition, the commenter requests the double comma on the 3rd line of the paragraph is corrected.

In response to the commenter’s request regarding grammar revisions, the following revision has been made to the Draft EIR Section 4.11.1(b), Pedestrian and Bicycle Facilities. The revision would not alter the impact analysis or findings of the Draft EIR and, as such, would not warrant recirculation of the Draft EIR.

While most of the City has sidewalks, , several older neighborhoods of the City have limited or lack pedestrian infrastructure.

In response to the commenter’s request, the following revision has been made to the Draft EIR Section 4.11.1(c), Transit Services. The revision would not alter the impact analysis or findings of the Draft EIR and, as such, would not warrant recirculation of the Draft EIR.

Vine Transit’s Route 29 (Napa-BART) Express connects the BART Station in El Cerrito to the Redwood Park-n-Ride in the City of Napa and stops in American Canyon at the Post Office on Crawford Way. In addition, Transit Route 11 (the Napa Vallejo Connector) and 11x (Napa Vallejo Express), provides public transit services north to the city of Napa and south to the Vallejo Ferry Terminal.

Response 9-11
The commenter requests the Americans with Disabilities Act of 1990 discussion on page 4.11-2 is updated to reflect the 2023 Final Rule addressing access improvements within the public right-ofway.

In response to the commenter’s request, the following revision has been made to the Draft EIR SubSection 4.11.2, Regulatory Setting, Page 4.11-2 of Section 4.11, Transportation. The revision would not alter the impact analysis or findings of the Draft EIR and, as such, would not warrant recirculation of the Draft EIR.

Americans with Disabilities Act of 1990
The Americans with Disabilities Act (ADA) of 1990 provides comprehensive rights and protections to individuals with disabilities. The goal of the ADA is to assure equality of opportunity, full participation, independent living, and economic self-sufficiency for people with disabilities. To implement this goal, the United States Access Board, an independent Federal agency created in 1973 to ensure accessibility for people with disabilities, has created accessibility guidelines for public rights-of-way. While these guidelines have not been formally adopted, they have been widely followed by jurisdictions and agencies nationwide in the last decade. The guidelines, last revised in July 2011, address various issues, including roadway design practices, slope and terrain issues, pedestrian access to streets, sidewalks, curb ramps, street furnishings, pedestrian signals, parking, and other components of public rights-of-way.

The guidelines were updated in August 2023 to address accessibility guidelines for pedestrian facilities in the public right-of-way. These guidelines inform federal, state, and local government agencies on how to make their pedestrian facilities, such as sidewalks, crosswalks, shared use paths, and on-street parking, accessible to people with disabilities. The guidelines cover the minimum scoping and technical requirements for various spaces and elements in the public right-of-way, such as pedestrian access routes, accessible pedestrian signals, curb ramps, detectable warning surfaces, crosswalks at roundabouts, on-street parking, transit stops. The guidelines apply to all proposed roadways in the City.

Minor Revisions to the Draft EIR
This chapter presents specific text changes made to the DEIR since its publication and public review.

The changes are presented in the order in which they appear in the original Draft EIR and are identified by the Draft EIR page number. Text deletions are shown in strikethrough, and text additions are shown in underline. The information contained within this chapter clarifies and expands on information in the Draft EIR and does not constitute “significant new information” requiring recirculation, as described in Section 4, Recirculation Not Warranted.

3.1 Revisions to the Draft EIR
Project Description
The following text has been revised on page 2-10 of Sub-Section 2.6.5, Mobility Updates, of Section 2, Project Description.

The City is in partnership with the Napa Valley Transportation Authority to identify improvements to SR 29, including landscaping improvements, pedestrian improvements, safety and transit movements, and multimodal features.

Environmental Setting
The following text has been revised on page 3-2 of Sub-Section 3.3, Cumulative Development, of Section 3, Environmental Setting.

By its nature, a general plan considers cumulative impacts insofar as it considers cumulative development that could occur within the Planning Area, including implementation of programs and policies included in regional planning documents.

Biological Resources
The following text has been revised on pages 4.3-3 and 4.3-14 of Section 4.4, Biological Resources.

Caltrans District 4 Pedestrian Plan
The Caltrans District 4 Pedestrian Plan, released in 2021, is a comprehensive guide aimed at improving pedestrian infrastructure across the nine-county Bay Area. This plan identifies existing conditions and prioritizes location-based needs to enhance pedestrian safety and accessibility. Developed in collaboration with local agencies, advocates, and the public, the plan serves as a crucial reference for planners and project designers. It promotes alternatives to driving, aiming to reduce congestion, lower greenhouse gas emissions, and encourage healthier lifestyles. The plan is part of the broader Bay Area Active Transportation Plan, which integrates pedestrian and bicycle needs into a cohesive strategy.

Caltrans District 4 Bike Plan
The Caltrans District 4 Bike Plan, finalized in 2018, evaluates the bicycling needs across the Bay Area's state transportation network. This plan identifies and prioritizes infrastructure improvements to enhance bicycle safety, mobility, and accessibility. It builds on the 2017 California State Bicycle and Pedestrian Plan and aims to create an integrated bicycle network that supports safe and convenient cycling for all ages and abilities. The plan was developed with input from the public and collaboration with local and regional partners, ensuring that proposed improvements align with local networks and address barriers to cycling.

Complete Streets Act
The California Complete Streets Act (AB 1358) adopted in 2008, requires that cities and other public agencies incorporate “Complete Street” policies when updating their General Plan Circulation Element. The term “Complete Streets” refers to a balanced, multimodal transportation network that meets the needs of all users of streets, including bicyclists, children, persons with disabilities, motorists, movers of commercial goods, pedestrians, public transportation, and seniors. A “Complete Street” is one that provides safe and convenient travel 567
City of American Canyon
American Canyon 2040 General Plan Update

in a manner that is suitable to the local context. Complete Streets make travel safe for all users, including bicyclists, pedestrians, motorists, transit vehicles, and people of all ages and abilities.

Each street does not need to provide dedicated space to all users, but the network must accommodate the needs of all users.

In 2021, Caltrans adopted Director’s Policy 37, a policy directive related to nonmotorized travel throughout the State. Director’s Policy 37 states:

The California Department of Transportation (Caltrans) recognizes that walking, biking, transit, and passenger rail are integral to our vision of delivering a brighter future for all through a world-class transportation network. Additionally, Caltrans recognizes that streets are not only used for transportation but are also valuable community spaces.

Accordingly, in locations with current and/or future pedestrian, bicycle, or transit needs, all transportation projects funded or overseen by Caltrans will provide comfortable, convenient, and connected complete streets facilities for people walking, biking, and taking transit or passenger rail unless an exception is documented and approved. When decisions are made not to include complete streets elements in capital and maintenance projects, the justification will be documented with final approval by the responsible District Director. Opportunities for complete streets exist in all phases of project development from planning and design to construction, operations, and maintenance. Complete streets projects should prioritize underserved communities that have been historically harmed and segmented by the transportation network and should serve people of all ages and abilities. Furthermore, Caltrans commits to removing unnecessary policy and procedural barriers and partnering with communities and agencies to ensure projects on local and state transportation systems improve the connectivity to existing and planned pedestrian, bicycle, and transit facilities, and accessibility to existing and planned destinations, where possible.

The following text has been revised within Sub-Section 4.11.2, Regulatory Setting, Page 4.11-4 of Section 4.11, Transportation.

In December 2018, Office of Planning and Research (OPR; now known as Office of Land Use and Climate Innovation) released the final update to CEQA Guidelines consistent with SB 743 that went into effect statewide on July 1, 2020, which state that vehicle miles traveled (VMT) is “generally” the most appropriate metric of transportation impacts to align local environmental review under CEQA with California’s long-term greenhouse gas emissions reduction goals. 568
Recirculation Not Warranted
Final Environmental Impact Report 4-1
Recirculation Not Warranted
As presented in Chapter 3, Minor Revisions to the Draft EIR, minor revisions to the Draft EIR would not result in new significant impacts or a substantial increase in the severity of previously identified significant impacts. The Minor Revisions (Chapter 3) identifies textual modifications to the Final EIR.

The revised text serves to amplify, correct, supplement or clarify, information in the public review Draft EIR. It does not substantively affect the level of impact nor the conclusions presented.

Therefore, recirculation of the Draft EIR is not warranted.

CEQA requires recirculation of a Draft EIR only when “significant new information” is added to a Draft EIR after public notice of the availability of the Draft EIR has occurred but before the EIR is certified (Public Resources Code Section 21092.1; CEQA Guidelines Section 15088.5). Recirculation is not required where the new information added to the EIR merely clarifies or amplifies or makes insignificant modifications in an adequate EIR (CEQA Guidelines Section 15088.5(b)).

The relevant portions of CEQA Guidelines Section 15088.5 (items a, b and e) read as follows:
(a) A lead agency is required to recirculate an EIR when significant new information is added to the EIR after public notice is given of the availability of the draft EIR for public review under Section 15087 but before certification. As used in this section, the term “information” can include changes in the project or environmental setting as well as additional data or other information. New information added to an EIR is not “significant” unless the EIR is changed in a way that deprives the public of a meaningful opportunity to comment upon a substantial adverse environmental effect of the project or a feasible way to mitigate or avoid such an effect (including a feasible project alternative) that the project’s proponents have declined to implement. “Significant new information” requiring recirculation include, for example, a disclosure showing that:
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.
4) The draft EIR was so fundamentally and basically inadequate and conclusory in nature that meaningful public review and comment were precluded. (b) Recirculation is not required where the new information added to the EIR merely clarifies or amplifies or makes insignificant modifications in an adequate EIR. (e) A decision not to recirculate an EIR must be supported by substantial evidence in the administrative record.

The revisions to Section 4.3, Biological Resources, refine Impact BIO-1 by clarifying its inclusion of mitigation measures BIO-1 through BIO-9. These mitigation measures were already included within the impact analysis and these revisions correct a typographical error. Recirculation is not required where new information added to the EIR merely clarifies or amplifies or makes minor modifications in an EIR (CEQA Guidelines Section 15088.5(b)). Additionally, the Revised Appendix Item B of the 569
City of American Canyon
American Canyon 2040 General Plan Update

Draft EIR to update the special status species table would not result in new significant impacts to special status species or require updated mitigation, as the current EIR sufficiently covers these revisions. Revisions to Section 4.3, Biological Resources, clarify and amplify the standards established by these measures and they would not result in any secondary or otherwise undisclosed effect.

Revisions to Section 4.11, Transportation, clarify and amplify the established standards for project oversight and compliance. These edits would not result in any secondary or otherwise undisclosed effect. As discussed above, recirculation is not required where new information added to the EIR merely makes minor modifications in an EIR (CEQA Guidelines Section 15088.5(b)). Therefore, the revisions to the regulatory setting of Section 4.11, Transportation, consistent of minor modifications to the EIR.

The information and revised wording of Mitigation Measure BIO-1 added to this Final EIR would not result in a substantial increase in the severity of an environmental impact, nor a new significant environmental impact that would result from the revised mitigation. The addition of an updated special status species table in Section 4.3, Biological Resources, and updated language in Section 4.11, Transportation, would not result in an impact that deprives the public of a meaningful opportunity to comment upon a substantial adverse environmental effect of the project or a feasible way to mitigate or avoid such an effect. Finally, additional information provided in this Final EIR does not present a feasible project alternative or mitigation measure considerably different from others previously analyzed in the EIR that the City has declined to adopt and that would lessen an environmental impact.

The information added to this Final EIR supplements, clarifies, amplifies, and corrects information in the Draft EIR. The City has reviewed the information in the Minor Revisions and has determined that it does not change any of the basic findings or conclusions of the EIR, does not constitute “significant new information” pursuant to CEQA Guidelines Section 15088.5, and does not require recirculation of the Draft EIR. This decision is supported by substantial evidence provided in this EIR. 570

BIO-1: Biological Resources Screening and Assessment
For projects proposed within undeveloped parcels, the City shall require project applicants to engage a qualified
biologist (having the appropriate education and experience level) to perform a baseline Biological Resources Screening and Assessment to determine whether projects proposed
within undeveloped parcels have any potential to impact special-status biological resources, inclusive of special-status plants and animals, sensitive vegetation communities
(including vernal pools and other wetlands), and critical habitat. If it is determined that the project has no potential to impact biological resources, no further action is required.

If the project would have the potential to impact biological resources, prior to construction, a qualified biologist shall conduct a project-specific biological analysis to document the existing biological resources within a project footprint plus a minimum buffer of 500 feet around the project
footprint, as is feasible, and to determine the potential impacts to those resources. The project-specific biological analysis shall evaluate the potential for impacts to all biological resources including, but not limited to specialstatus species, nesting birds, wildlife movement, sensitive plant communities, critical habitats, and other resources judged to be sensitive by local, state, and/or federal

• When possible, removal of trees/structures identified as suitable roosting habitat shall be conducted during
seasonal periods of bat activity, including the following:
o Between September 1 and about October
15, or before evening temperatures fall
below 45 degrees Fahrenheit and/or more
than 0.5 inch of rainfall within 24 hours
occurs.
o Between March 1 and April 15, or after
evening temperatures rise above 45
degrees Fahrenheit and/or no more than

• If a tree/structure must be removed during the
breeding season and is identified as potentially
containing a colonial maternity roost, then a qualified biologist shall conduct acoustic emergence surveys or
implement other appropriate methods to further
evaluate if the roost is an active maternity roost. Under the biologist’s guidance, the contractor shall
implement measures similar to or exceeding the

one. The noise and vibration disturbance, together with the visible alteration of the tree, is very effective in causing bats that emerge nightly to feed to not return
to the roost that night. The remainder of the tree is
removed on day two.
• Prior to the demolition of vacant structures within the project site, a qualified biologist shall conduct a
focused habitat assessment of all structures to be
demolished. The habitat assessment shall be conducted
enough in advance to ensure the commencement of
building demolition can be scheduled during seasonal
periods of bat activity (see above), if required. If no signs of day roosting activity are observed, no further actions will be required. If bats or signs of day roosting by bats are observed, a qualified biologist will prepare specific recommendations such as partial dismantling
to cause bats to abandon the roost, or humane
eviction, both to be conducted during seasonal periods
of bat activity, if required.

shall be installed near the project site. The number of bat boxes installed will depend on the size of the
hibernaculum and shall be determined through
consultation with CDFW. If a maternity colony has

A Phase I pedestrian survey shall be undertaken in future project areas that are undeveloped to locate any surface cultural materials. By performing a records search, a SLF search, and a Phase I survey, a qualified archaeologist shall be able to classify the future project area as having high, medium, or low sensitivity for archaeological resources.

If the Phase I archaeological survey identifies resources that may be affected by the future project, the archaeological resources assessment shall also include Phase II testing and evaluation. If resources are determined significant or unique through Phase II testing and site avoidance is not possible, appropriate site-specific mitigation measures shall be
identified in the Phase II evaluation. These measures may include, but would not be limited to, a Phase III data
recovery program, avoidance, or other appropriate actions to be determined by a qualified archaeologist. If significant archaeological resources cannot be avoided, impacts may be reduced to less than significant level by filling on top of the sites rather than cutting into the cultural deposits.

Alternatively, and/or in addition, a data collection program may be warranted, including mapping the location of
artifacts, surface collection of artifacts, or excavation of the cultural deposit, to characterize the nature of the buried portions of sites. Curation of the excavated artifacts or samples would occur as specified by the archaeologist. The archaeological resources assessment shall be reviewed and approved by the City prior to project approval.

The City shall review and approve the
archeological resources assessment
submitted by the applicant and
prepared by a qualified archaeologist.

If site-specific archaeological
mitigation is identified, the City shall
ensure that such measures are
implemented or archaeological
resources are avoided to the extend
feasible.

CUL-3: Unanticipated Discoveries
An Archaeologist who meets the Secretary of the Interior’s Professional Qualification Standards for archaeology shall be present on-site during all earth disturbing activities. If cultural resources are encountered during ground-disturbing activities, work within 100 feet of the area shall be halted and the contractor shall contact an archaeologist meeting the Secretary of the Interior’s Professional Qualification Standards for archaeology in either prehistoric or historic archaeology immediately to evaluate the find. If necessary, the evaluation may require preparation of a treatment plan and archaeological testing for CRHR eligibility. If the discovery proves to be significant under CEQA and cannot be avoided by the project, additional work, such as excavating the cultural deposit to fully characterize its extent and collecting and curating artifacts may be warranted to
mitigate any significant impacts to cultural resources. If archaeological resources of Native American origin are
identified during construction, a qualified archaeologist will consult with the City to begin Native American consultation procedures. Periodic reports of the find and subsequent evaluations shall be submitted to the City during
construction.

The City shall review reports of any
unanticipated findings and

Introduction
Findings of Fact and Statement of Overriding Considerations 1 1 Introduction
A Draft Environmental Impact Report (Draft EIR) was prepared for the American Canyon 2040 General Plan Update (project), and the City of American Canyon (City) filed a notice of completion (NOC) with the Governor’s Office of Planning and Research to begin the 45-day public review period (Public Resources Code [PRC] Section 21161), which began on September 27, 2024, and ended on December 27, 2024. The Draft EIR was made available on the City’s website.1 In addition, the Draft EIR was made available for review at the City’s offices at 4381 Broadway Street, Suite 201; the City Library at 300 Crawford Way; and the Active Adults Center at 2185 Elliot Drive. As a result of these notification efforts, the City received eight written comments on the content of the Draft EIR.

After close of the Draft EIR public review and comment period, a Final EIR consisting of responses to comments and minor revisions to the Draft EIR was prepared for City Council. On May 20, 2025, the City Council, at a public hearing, is expected to decide on the certification of the Final EIR and approval of the project. The public hearing will be simultaneously held virtually and in person.

The Findings of Fact (Findings) and Statement of Overriding Considerations (SOC) presented herein address the environmental effects associated with the project that are described and analyzed within the Final EIR, reflect the Council’s determinations about feasible mitigation measures, and the adequacy of the Final EIR. These Findings have been made pursuant to the California Environmental Quality Act (CEQA; California Public Resources Code Section 21000 et seq.), specifically Public Resources Code Sections 21081 and 21081.6, as well as the CEQA Guidelines (14 CCR 15000 et seq.) Sections 15091 and 15093.

Public Resources Code Section 21081 and CEQA Guidelines Section 15091 require that the City, as the Lead Agency for this project, prepare written findings for any identified significant environmental effects along with a brief explanation of the rationale for each finding. Specific findings under CEQA Guidelines Section 15091(a) are:
(1) Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effects 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.

Furthermore, in accordance with Public Resources Code Section 21081 and CEQA Guidelines Section 15093, whenever significant effects cannot be mitigated to below a level of significance, the City as the decision-making agency is required to balance, as applicable, the benefits of the project against its unavoidable environmental risks when determining whether to approve the project. If the benefits of a project outweigh the unavoidable adverse environmental effects, the adverse effects may be considered “acceptable,” in which case the lead agency must adopt a formal SOC. 1 Draft EIR for the project is available here: https://portal.laserfiche.com/Portal/DocView.aspx?id=232476&repo=r-f53bdda4 611
City of American Canyon
American Canyon 2040 General Plan Update
2 The Final EIR identified potentially significant environmental effects that could result from the project but could be reduced to a less than significant level through implementation of mitigation measures. Those effects were related to aesthetics (impacts related to anticipated construction and operational lighting from development between now and the 2040 plan horizon year), air quality (impacts related to exposing sensitive receptors to pollutant concentrations and odors), biological resources (impacts to special status species), cultural resources (impacts related to historical structures, archaeological resources, and human remains), noise (impacts related to groundborne vibration), paleontological resources, and wildfire (impacts related to exposing people and structures to wildfire risk).

Significant and unavoidable impacts associated with greenhouse gas (GHG) emissions (impacts related to conflicts with state GHG reduction goals), noise (impacts related to construction noise and operational traffic noise), and transportation (impacts related to vehicle miles traveled [VMT]) were identified because mitigation measures would not reduce impacts to a less than significant level, and thus a statement of overriding considerations is required. 612
Project Description
Findings of Fact and Statement of Overriding Considerations 3 2 Project Description
The project is an update to the City’s current General Plan, which includes the following chapters:

Introduction, Land Use Element, Housing Element, Economic Development Element, Mobility (Circulation) Element, Utilities Element, Public Services and Facilities Element, Parks and Recreation Element, Natural and Historic & Cultural Resources Element, Geology Element, Flood Hazards Element, and Noise Element.

The General Plan (project) establishes the City’s vision for future development through the horizon year of 2040. The General Plan will serve as the City’s primary guide for future land use and development decisions in a way that meets the community needs and priorities while serving as a key tool for influencing and improving the quality of life for residents and businesses. As such, it serves as the “blueprint” for future development and conservation of a community. The 2040 General Plan Update will help the City plan for important community issues, such as community growth; health, housing, mobility, and infrastructure needs; climate change; and environmental protection. It will also set the stage for future social, physical, and economic development of the City.

The project would change some of the land use designations; however, these changes primarily resolve inconsistences between existing uses and the General Plan land use designations. As a part of the project, the City would consider an update to the Urban Limit Line to include the Hess/Laird Property and two parcels located in the vicinity of S. Kelly Road and State Route (SR) 29.

Consideration of an expansion of the Urban Limit Line is an administrative process that would not result in an environmental impacts and is not discussed in the Final EIR. Overall, compared to existing conditions, the project could add 3,379 residential units and approximately 5,704,000 square feet of commercial, retail, hotel, industrial, warehouse, and research and development (R&D) uses.

The project includes a Mobility Element, which provides a vision and guiding principles for the transportation system. The Mobility Element identifies the following proposed major circulation improvements in American Canyon:
 The City partnership with the Napa Valley Transportation Authority to identify improvements to SR 29, including landscaping improvements, pedestrian improvements, and multimodal features.
 Newell Drive extension from Watson Ranch to Highway 29 at Green Island Road (2-Lane Major Collector Road and 4-Lane Arterial)
 Green Island Road reconstruction from a 2-lane Arterial to a 3-Lane Arterial  West Side Connector (2-Lane Major Collector)
 Eucalyptus Drive extension from Theresa Avenue to Broadway (2-Lane Major Collector)  Rio Del Mar or South Napa Junction Road, including new at-grade crossing from Broadway to Newell Drive (2-Lane Major Collector)
 Napa Junction Road from Theresa Avenue to Hess Road (2-Lane Minor Collector)  Newell Drive Railroad Overcrossing
 American Canyon Road Pedestrian Crossing
 Donaldson Way Pedestrian Crossing
 Napa Junction Road Pedestrian Crossing

City of American Canyon
American Canyon 2040 General Plan Update
4 3 Project Objectives
The Technical 2040 General Plan will serve as a long-term framework for future growth and development, represents the community’s view of its future, and contains the goals and policies upon with the City Council, Planning Commission, and the entire community will base land use and resource decisions. The Technical 2040 General Plan will provide a contemporary plan that will guide American Canyon though the next 20 years and comply with State General Plan guidelines and law.

The Technical 2040 General Plan identifies the following three fundamental roles of the City:

1. The City should be home for a residential population, internally accommodating a sufficient range of uses to support the needs of residents (including a mix of housing types, commercial services, entertainment, employment, recreation, education, health, religious, cultural facilities, transportation services, and open space). At the present time, many of these uses are located outside the City, which necessitates extensive travel by residents to access these services.

2. The City should be a center of employment and commerce for regional, as well as local residents.

This will provide an opportunity to capitalize upon: (1) the cluster of uses which have developed in the Green Island Industrial Park; (2) the proximity of the City to the Napa County Airport and Southern Pacific railroad, and (3) the relationship of the City to the agricultural and vineyard industries of Napa County.

3. The City can capture visitors to the Napa Valley by providing uses which capitalize on the unique environmental setting of the foothills, river valleys, and agriculture. Environmental educational facilities, such as wetlands interpretative centers, overnight camping and recreational vehicle facilities, river recreational facilities such as boating, golf courses, and hotel/motels and restaurants are representative of the range of uses which may be considered. 614

Having received, reviewed, and considered the information in the Final EIR for this project, as well as the supporting administrative record, the City of American Canyon makes findings pursuant to, and in accordance with, Sections 21081, 21081.5, and 21081.6 of the Public Resources Code.

Environmental Effects Found Not to be Significant
Through project scoping and the environmental analysis contained within the Final EIR, it was determined that the project would not result in potentially significant effects on the environment for all CEQA Appendix G checklist questions related to land use and planning, population and housing, public services and recreation, utilities and service systems, and tribal cultural resources. In addition, it was determined that the project would not result in potentially significant effects on the environment for CEQA Appendix G checklist questions within the following issue areas:
 Aesthetics (impacts to scenic vistas, state scenic highways, and conflicts with zoning)  Air quality (impacts related to consistency with the Bay Area Air Quality Management District’s 2017 Clean Air Plan and net increases in criteria pollutants)  Biological resources (impacts to riparian habitat and sensitive natural communities, fish and wildlife migration, conflicts with policies designed to protect biological resources, and conflicts with an adopted habitat conservation plan)
 Noise (impacts related to airport noise)
 Transportation (impacts related to conflicts with policies addressing the circulation system, increasing transportation hazards, and resulting in inadequate emergency access)  Wildfire (impacts related to emergency access, installation of utilities, and risks associated with post-fire instability).

No further findings are required for these subject areas.

Findings for Significant but Mitigated Effects
The following findings are hereby made by the City of American Canyon for the significant but mitigable environmental effects identified in the EIR related to aesthetics (impacts related to additional construction and operational lighting), air quality (impacts related to exposing sensitive receptors to pollutant concentrations and odors), biological resources (impacts to special status species), cultural resources (impacts related to historical structures, archaeological resources, and human remains), noise (impacts related to groundborne vibration), paleontological resources, and wildfire (impacts related to exposing people and structures to wildfire risk).

4.2.1 Aesthetics – Impact AES-4
Construction and operation of future development facilitated by the project could create new sources of light or glare that could adversely affect the visual environment. Impacts would be less than significant with mitigation.

6 Finding
Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effects as identified in the Final EIR (CEQA Guidelines Section 15091[a][1]). Implementation of Mitigation Measures AES-1 and AES-2 would reduce potential impacts related to additional construction and operational lighting to a less than significant level.

Explanation
Implementation of Mitigation Measure AES-1 would require a construction lighting plan for projects that would require nighttime construction and Mitigation Measure AES-2 would require the preparation of a photometric plan. Implementation of Mitigation Measures AES-1 and AES-2 would ensure that lighting and glare is minimized during construction and operation of future development. With implementation of Mitigation Measures AES-1 and AES-2, impacts would be less than significant.

Mitigation Measure
Pursuant to CEQA Guidelines Section 15091, the following mitigation measures have been included in a MMRP that is to be adopted concurrently with these findings.

AES-1 Construction Lighting Plan
Prior to nighttime construction, if needed for a particular project, project applicants shall submit a construction lighting plan to the City for review and approval. The construction lighting plan shall ensure that the minimum amount of lighting is used to meet safety requirements and ensure no spillover occurs to nearby sensitive uses. All lighting shall be directed downward and away from surrounding land uses.

AES-2 Operational Lighting Plan
Prior to discretionary project approval, the project applicant shall prepare and submit a photometric plan to the City for review and approval which demonstrates that all exterior light fixtures will be directed downward or employ full cut-off fixtures to prevent light spillage. The approved plan shall be incorporated into project design plans.

4.2.2 Air Quality – Impact AQ-3
Construction activities for projects lasting longer than two months or located within 1,000 feet of sensitive receptors could expose sensitive receptors to substantial pollutant concentrations.

Implementation of the project may also expose sensitive receptors to operational sources of toxic air contaminants. Impacts would be less than significant with mitigation.

Finding
Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effects as identified in the Final EIR (CEQA Guidelines Section 15091[a][1]). Implementation of Mitigation Measures AQ-1 through AQ-3 would reduce potential impacts related to exposing sensitive receptors to substantial pollutant concentrations to a less than significant level.
616
Findings of Fact
Findings of Fact and Statement of Overriding Considerations 7 Explanation
Implementation of Mitigation Measure AQ-1 requires the preparation of construction health risk assessments for developments that meet specific criteria and implementation of measures to reduce construction emissions. Mitigation Measures AQ-2 requires the preparation of operational health risk assessments for development that places sensitive receptors within 500 feet of a major source of toxic air contaminants and implementation of measures to reduce exposure to toxic air contaminants. Mitigation Measures AQ-3 requires the preparation of operational health risk assessments for industrial, warehousing, and commercial land uses that meet specific criteria and implementation of measures to reduce operational emissions.

Mitigation Measure
Pursuant to CEQA Guidelines Section 15091, the following mitigation measures have been included in a MMRP that is to be adopted concurrently with these findings.

AQ-1 Conduct Construction Health Risk Assessment
Prior to issuance of a grading or building permit, whichever occurs first, the applicant shall submit to the City a construction health risk assessment (HRA) in accordance with BAAQMD recommendations for any development project that has at least one the following characteristics:
 The project is located within 1,000 feet of sensitive receptors.  Project construction would last longer than two months.  Project construction would not utilize equipment rated USEPA Tier 4 (for equipment of 50 horsepower or more); construction equipment fitted with Level 3 Diesel Particulate Filters (for all equipment of 50 horsepower or more); or alternative fuel construction equipment.

If the HRA determines that construction will exceed BAAQMD significance thresholds, the HRA shall provide mitigation measures to reduce the impact to less than significant, including but not limited to requiring the use of Tier 4 engines, Level 3 Diesel Particulate Filters, and/or alternative fuel construction equipment.

AQ-2 Reduce operational Toxic Air Contaminants Near Sensitive Receptors For new sensitive receptors proposed within 500 feet of a major source of TAC (high-volume roadways with 10,000 vehicles or more per day), the project applicant shall prepare an operational health risk assessment for the City’s review and approval. If TAC exposure at new sensitive receptor sites would exceed BAAQMD health risk thresholds, the project applicant shall include mechanical air filtration or other measures to reduce health risk exposure to acceptable levels.

AQ-3 Conduct Operational Health Risk Assessment
Prior to permit approval for industrial, warehousing, or commercial land uses that would generate at least 100 diesel trucks per day or 40 or more trucks with diesel-powered transport refrigeration units per day, the applicant shall submit an operational health risk assessment (HRA) or submit proof that an HRA is not required in accordance with BAAQMD thresholds to the City for review and approval. If required by the City, the operational HRA shall be prepared in accordance with the Office of Environmental Health Hazard Assessment and BAAQMD requirements, and impacts shall be mitigated to an acceptable level. Typical measures to reduce risk impacts may include, but are not limited to:
617

8  Restricting idling on-site beyond Air Toxic Control Measures idling restrictions, as feasible.  Electrifying warehousing docks.
 Truck Electric Vehicle (EV) Capable trailer spaces.
 Requiring use of newer equipment and/or vehicles.
 Restricting off-site truck travel through the creation of truck routes.

The operational HRA shall be provided to the City for review and concurrence prior to project approval.

4.2.3 Air Quality – Impact AQ-4
The project would not create objectionable odors that could adversely affect a substantial number of people. Impacts related to odors would be less than significant with mitigation.

Explanation
Implementation of Mitigation Measure AQ-4 requires the preparation of an odor management plan for projects with potential to emit nuisance odors beyond the project’s property line. Odor impacts would be less than significant with implementation of Mitigation Measure AQ-4.

Mitigation Measure
Pursuant to CEQA Guidelines Section 15091, the following mitigation measures have been included in a MMRP that is to be adopted concurrently with these findings.

AQ-4 Reduce Operational Odor Impacts
Prior to discretionary approval by the City, if it is determined by the City that a development project has the potential to emit nuisance odors beyond the property line, the project applicant shall prepare an odor management plan and submit it to the City for review and approval. Facilities that have the potential to generate nuisance odors include, but are not limited to:
 Wastewater treatment plants
 Composting, green waste, or recycling facilities
 Fiberglass manufacturing facilities
 Painting/coating operations
 Large-capacity coffee roasters
 Food-processing facilities
The odor management plan shall demonstrate compliance with the latest BAAQMD screening distances and guidelines. The odor management plan shall identify the best available control technologies for toxics (T-BACTs) that will be utilized to reduce potential odors to acceptable levels, 618
Findings of Fact
Findings of Fact and Statement of Overriding Considerations 9 including appropriate enforcement mechanisms. T-BACTs may include but are not limited to scrubbers (i.e., air pollution control devices) at the industrial facility. T-BACTs identified in the odor management plan shall be identified as mitigation measures in the documents prepared for the development project and/or incorporated into the project’s site plan.

4.2.4 Biological Resources – Impact BIO-1
The project could have the potential to have an adverse impact on special status species.

Implementation of federal, state, and local regulations and policies, as well as Mitigation Measures BIO-1 through BIO-9, would ensure development facilitated by the project would not have a substantial adverse effect on candidate, sensitive, or special status species. This impact would be less than significant with mitigation.

Explanation
Implementation of Mitigation Measure BIO-1 through BIO-9 would reduce potential impacts to special-status species, nesting birds, and roosting bats to a less than significant level by requiring Biological Resources Screening and Assessments, avoidance and minimization, habitat restoration, and preconstruction surveys.

Mitigation Measure
Pursuant to CEQA Guidelines Section 15091, the following mitigation measures have been included in a MMRP that is to be adopted concurrently with these findings.

BIO-1 Biological Resources Screening and Assessment
For projects proposed within undeveloped parcels, the City shall require project applicants to engage a qualified biologist (having the appropriate education and experience level) to perform a baseline Biological Resources Screening and Assessment to determine whether projects proposed within undeveloped parcels have any potential to impact special-status biological resources, inclusive of special-status plants and animals, sensitive vegetation communities (including vernal pools and other wetlands), and critical habitat. If it is determined that the project has no potential to impact biological resources, no further action is required. If the project would have the potential to impact biological resources, prior to construction, a qualified biologist shall conduct a projectspecific biological analysis to document the existing biological resources within a project footprint plus a minimum buffer of 500 feet around the project footprint, as is feasible, and to determine the potential impacts to those resources. The project-specific biological analysis shall evaluate the potential for impacts to all biological resources including, but not limited to special-status species, nesting birds, wildlife movement, sensitive plant communities, critical habitats, and other resources judged to be sensitive by local, state, and/or federal agencies. If the project would have the potential to impact these resources, the following mitigation measures (mitigation measures BIO-2 through BIO-8) shall be incorporated, as applicable, to reduce impacts to a less than significant level. 619
City of American Canyon
American Canyon 2040 General Plan Update
10 Pending the results of the project-specific biological analysis, design alterations, further technical studies (e.g., protocol surveys) and consultations with the USFWS, CDFW, and/or other local, state, and federal agencies may be required. Note that specific surveys described in the mitigation measures below may be completed as part of the project-specific biological analysis where suitable habitat is present.

BIO-2 Special-status Plant Species Surveys
If the project-specific Biological Resources Screening and Assessment (Mitigation Measure BIO-1) determines that there is potential for significant impacts to federally or state-listed plants or regional population level impacts to species with a CRPR of 1B or 2B from project development, a qualified biologist shall complete surveys for special-status plants prior to any vegetation removal, grubbing, or other construction activity (including staging and mobilization). The surveys shall be floristic in nature and shall be seasonally timed to coincide with the target species. All plant surveys shall be conducted by a qualified biologist during the blooming season prior to development permit approval. All special-status plant species identified on site shall be mapped onto a site-specific aerial photograph or topographic map with the use of Global Positioning System unit. Surveys shall be conducted in accordance with the most current protocols established by the CDFW, USFWS, and the local jurisdictions if said protocols exist. A report of the survey results shall be submitted to the City, and the CDFW and/or USFWS, as appropriate, for review and/or approval.

BIO-3 Special-status Plant Species Avoidance, Minimization, and Mitigation If federally and/or state-listed or CRPR 1B or 2 species are found during special-status plant surveys (pursuant to Mitigation Measure BIO-2), and would be directly impacted, or there would be a population-level impact to non-listed sensitive species, then the project shall be re-designed to avoid impacting those plant species, where feasible. Rare and listed plant occurrences that are not within the immediate disturbance footprint but are located within 50 feet of disturbance limits shall have bright orange protective fencing installed at least 30 feet beyond their extent, or other distance as approved by a qualified biologist, to protect them from harm.

BIO-4 Habitat Restoration Plan
If federally or state-listed plants or non-listed special-status CRPR 1B and 2 plant populations identified during special status plant surveys (pursuant to Mitigation Measure BIO-2), cannot be avoided, and will be impacted by development, all impacts shall be mitigated by the applicant at a ratio not lower than 1:1 per acre of impact (and 1:1 per tree), and to be determined by the City (in coordination with CDFW and USFWS as and if applicable) for each species as a component of habitat restoration. A qualified biologist shall prepare and submit a restoration plan to the City for review and approval prior to City approval of project plans. (Note: if a federally and/or state-listed plant species will be impacted, the restoration plan shall be submitted to the USFWS and/or CDFW for review, and federal and/or state take authorization may be required by these agencies.) The restoration plan shall include, at a minimum, the following components:

1. Description of the project/impact site (i.e., location, responsible parties, areas to be impacted by habitat type).

2. Goal(s) of the compensatory mitigation project (type[s] and area[s]) of habitat to be established, restored, enhanced, and/or preserved; specific functions and values of habitat type[s] to be established, restored, enhanced, and/or preserved).
620
Findings of Fact

3. Description of the proposed compensatory mitigation site (location and size, ownership status, existing functions, and values).

4. Implementation plan for the compensatory mitigation site (rationale for expecting implementation success, responsible parties, schedule, site preparation, planting plan).

5. Maintenance activities during the monitoring period, including weed removal as appropriate (activities, responsible parties, schedule).

7. Success criteria based on the goals and measurable objectives; said criteria to be, at a minimum, at least 80 percent survival of container plants and 30 percent relative cover by vegetation type or other industry standards as determined by a qualified restoration specialist.

8. An adaptive management program and remedial measures to address any shortcomings in meeting success criteria.

9. Notification of completion of compensatory mitigation and agency confirmation.

10. Contingency measures(initiating procedures, alternative locationsfor contingency compensatory mitigation, funding mechanism).

11. All nursery plants used in restoration shall be inspected for sudden oak death.

BIO-5 Endangered/Threatened Special-status Species Habitat Assessments and Protocol Surveys
If the results of the project-specific biological analysis (Mitigation Measure BIO-1) determine that suitable habitat may be present for federal or state listed, candidate, or proposed species, protocol habitat assessments/surveys shall be completed in accordance with current CDFW and/or USFWS protocols prior to issuance of any construction permits. If, through consultation with the CDFW and/or USFWS, it is determined that protocol habitat assessments/surveys are not required, the applicant shall complete and document this consultation and submit it to the City prior to issuance of any construction permits. Each protocol has different survey and timing requirements. The applicant shall be responsible for ensuring they understand the protocol requirements and shall hire a qualified biologist to conduct protocol surveys. (Note: if a federally and/or state-listed wildlife species will be impacted, federal and/or state take authorization may be required by USFWS and CDFW.)
BIO-6 Endangered/Threatened Animal Species Avoidance and Minimization The following measures shall be applied to impacted aquatic and/or terrestrial animal species identified by the project-specific Biological Resources Screening and Assessment required under Mitigation Measure BIO-1.

1. Ground disturbance shall be limited to the minimum necessary to complete the project. A qualified biologist shall flag the project limits of disturbance. Areas of special biological concern within or adjacent to the limits of disturbance shall have highly visible orange construction fencing installed between said area and the limits of disturbance.

2. All projects occurring within/adjacent to aquatic habitats (including riparian habitats and wetlands) shall be completed between April 1 and October 31, if feasible, to avoid impacts to sensitive aquatic species. Any work outside these dates would require project-specific approval from the City and may be subject to regulatory agency approval. 621
City of American Canyon
American Canyon 2040 General Plan Update
12 3. All projects occurring within or adjacent to sensitive habitats that may support federally and/or state-listed endangered/threatened species shall have a CDFW- and/or USFWS-approved biologist present during all initial ground disturbing/vegetation clearing activities. Once initial ground disturbing/vegetation clearing activities have been completed,said biologistshall conduct daily pre-activity clearance surveys for endangered/threatened species. Alternatively, and upon approval of the CDFW and/or USFWS, said biologist may conduct site inspections at a minimum of once per week to ensure all prescribed avoidance and minimization measures are fully implemented.

4. No endangered/threatened species shall be captured and relocated without express permission from the CDFW and/or USFWS.

5. If at any time during project construction an endangered/threatened species enters the construction site or otherwise may be impacted by the project, all project activities shall cease. A CDFW/USFWS-approved biologist shall document the occurrence and consult with the CDFW and USFWS, as appropriate, to determine whether it was safe for project activities to resume.

The placement of the fence shall be at the discretion of the CDFW/USFWS-approved biologist.

This fence shall consist of solid silt fencing placed at a minimum of three feet above grade and two feet below grade and shall be attached to wooden stakes placed at intervals of not more than five feet. The applicant shall inspect the fence weekly and following rain events and high wind events and shall be maintained in good working condition until all construction activities are complete.

7. All vehicle maintenance/fueling/staging shall occur not less than 100 feet from any riparian habitat or water body, including seasonal wetland features. Suitable containment procedures shall be implemented to prevent spills. A minimum of one spill kit shall be available at each work location near riparian habitat or water bodies.

8. No equipment shall be permitted to enter wetted portions of any affected drainage channel or wetland.

9. At the end of each workday, excavations shall be secured with a cover or a ramp provided to prevent wildlife entrapment.

10. All trenches, pipes, culverts, or similar structures shall be inspected for animals prior to burying, capping, moving, or filling.

11. Considering the potential for the project to impact federally and state-listed species and their habitat, the City shall contact CDFW and USFWS to identify mitigation banks within Napa County during project development. If the results of the project-specific biological analysis (Mitigation Measure BIO-1) determine that impacts to federally and state threatened or endangered species habitat are expected, City and/or applicant shall explore species-appropriate mitigation bank(s) servicing the region for purchase of mitigation credits.

12. Prior to grading and construction in natural areas of containing suitable upland habitat, a qualified biologist shall conduct a preconstruction survey as determined necessary during the biological analysis (Mitigation Measure BIO-1). The survey should include a transect survey over the entire project disturbance footprint (including access and staging areas), and mapping ofsuitable habitat features, such as burrows, that are potentially suitable for listed species. If any listed species are detected, no work shall be conducted until the individual(s) leaves the site of their own accord, unless federal and/or state “take” authorization has been issued for relocation. Typical 622
Findings of Fact
Findings of Fact and Statement of Overriding Considerations 13 preconstruction survey procedures, such as burrow scoping and burrow collapse, cannot be conducted without federal and state permits. If any life stage of listed species are found within the survey area, the City and/or applicant shall consult with the USFWS and CDFW to determine the appropriate course of action to comply with the FESA and CESA, if permits are not already in place at the time of construction.

BIO-7 Pre-Construction Bird Surveys, Avoidance, and Notification For all future development under the 2040 General Plan, construction activities initiated during the bird nesting season (February 1 – September 15), involving removal of vegetation (e.g. trees and shrubs), abandoned structures, or other nesting bird habitat, a pre-construction nesting bird survey shall be conducted no more than 5 days prior to initiation of ground disturbance and vegetation removal. The nesting bird pre-construction survey shall be conducted on foot and shall include a buffer around the construction site at a distance determined by a qualified biologist, including staging and storage areas. The minimum survey radii surrounding the work area shall be the following: 250 feet for non-raptors and 1,000 feet for raptors. The survey shall be conducted by a qualified biologist familiar with the identification of avian species known to occur in the American Canyon region. If construction lapses for seven days or longer, the qualified biologist shall conduct another focused survey before project activities are reinitiated. If nests are found, an avoidance buffer shall be determined by the biologist dependent upon the species, the proposed work activity, and existing disturbances associated with land uses outside of the site. The qualified biologist shall observe the active nest to establish a behavioral baseline of the adults and nestlings, if present. The qualified biologist shall continuously monitor the active nests to detect signs of disturbance and behavioral change as a result of construction impacts, such as noise, vibration, odors, or worker/equipment motion. If signs of disturbance and behavioral changes are observed, the qualified biologist shall cease work causing those changes and may contact CDFW or USFWS for guidance. The buffer shall be demarcated by the biologist with bright orange construction fencing, flagging, construction lathe, or other means to demarcate the boundary. All construction personnel shall be notified of the buffer zone as an “Ecologically Sensitive Area” and to avoid entering the buffer zone during the nesting season. No ground disturbing activities shall occur within the buffer until the biologist has confirmed that breeding/nesting is completed and the young have fledged the nest. Encroachment into the buffer shall occur only at the discretion of the qualified biologist on the basis that the encroachment will not be detrimental to an active nest. A report summarizing the pre-construction survey(s) shall be prepared by a qualified biologist and shall be submitted to the City prior to the commencement of construction activities.

Project site plans shall include a statement acknowledging compliance with the federal MBTA and California Fish and Game Code that includes avoidance of active bird nests and identification of Best Management Practices to avoid impacts to active nests, including checking for nests prior to construction activities during February 1 to September 15, and what to do if an active nest is found so that the nest is not inadvertently impacted during grading or construction activities.

BIO-8 Roosting Bat Surveys and Avoidance Prior to Removal For all future development under the 2040 General Plan that will require the removal of large trees (greater than 20 inches in diameter at five feet from the ground), abandoned buildings, bridges, or other suitable roosting structure identified during the Biological Resources Screening and Assessment (Mitigation Measure BIO-1), prior to tree and/or structure removal, a qualified biologist shall conduct a focused survey of all trees and structures to be removed or impacted by construction activities to determine whether active roosts of special-status bats are present on site. 623
City of American Canyon
American Canyon 2040 General Plan Update
14 Tree or structure removal shall be planned for either the spring or the fall, and timed to ensure both suitable conditions for the detection of bats and adequate time for tree and/or structure removal to occur during seasonal periods of bat activity exclusive of the breeding season, as described below.

If roosts are present, the biologist shall prepare a site-specific roosting bat protection plan to be implemented by the contractor following the City’s approval. Additionally, the qualified biologist shall determine compensatory mitigation for temporary or permanent habitat loss due to tree removal, in conjunction with CDFW. The plan shall incorporate the following guidance as appropriate:
 When possible, removal of trees/structures identified as suitable roosting habitat shall be conducted during seasonal periods of bat activity, including the following:
 Between September 1 and about October 15, or before evening temperatures fall below 45 degrees Fahrenheit and/or more than 0.5 inch of rainfall within 24 hours occurs.  Between March 1 and April 15, or after evening temperatures rise above 45 degrees Fahrenheit and/or no more than 0.5 inch of rainfall within 24 hours occurs.  If a tree/structure must be removed during the breeding season and is identified as potentially containing a colonial maternity roost, then a qualified biologist shall conduct acoustic emergence surveys or implement other appropriate methods to further evaluate if the roost is an active maternity roost. Under the biologist’s guidance, the contractor shall implement measures similar to or exceeding the following:
 If it is determined that the roost is not an active maternity roost, then the roost may be removed in accordance with the other requirements of this measure.  If it is found that an active maternity roost of a colonial roosting species is present, the roost shall not be disturbed during the breeding season (April 15 to August 31).  Tree removal procedures shall be implemented using a two-step tree removal process. This method is conducted over two consecutive days and works by creating noise and vibration by cutting non-habitat branches and limbs from habitat trees using chainsaws only (no excavators or other heavy machinery) on day one. The noise and vibration disturbance, together with the visible alteration of the tree, is very effective in causing bats that emerge nightly to feed to not return to the roost that night. The remainder of the tree is removed on day two.  Prior to the demolition of vacant structures within the project site, a qualified biologist shall conduct a focused habitat assessment of all structures to be demolished. The habitat assessment shall be conducted enough in advance to ensure the commencement of building demolition can be scheduled during seasonal periods of bat activity (see above), if required. If no signs of day roosting activity are observed, no further action will be required. If bats or signs of day roosting by bats are observed, a qualified biologist will prepare specific recommendations such as partial dismantling to cause bats to abandon the roost, or humane eviction, both to be conducted during seasonal periods of bat activity, if required.  If the qualified biologist determines a roost is used by a large number of bats (large hibernaculum), bat boxes shall be installed near the project site. The number of bat boxes installed will depend on the size of the hibernaculum and shall be determined through consultation with CDFW. If a maternity colony has become established, all construction 624
Findings of Fact
Findings of Fact and Statement of Overriding Considerations 15 activities shall be postponed within a 500-foot buffer around the maternity colony until it is determined by a qualified biologist that the young have dispersed. Once it has been determined that the roost is clear of bats, the roost shall be removed immediately.

BIO-9 Conduct Pre-construction Crotch’s Bumblebee surveys and Implement Avoidance Measures
If the results of the project-specific biological analysis (Mitigation Measure BIO-1) determine that suitable habitat may be present for Crotch’s bumble bee, a habitat assessment shall be performed by a qualified biologist knowledgeable and experienced with Crotch’s bumblebee and the habitat in which they occur. If the biologist determines that suitable habitat for Crotch’s bumblebee is present, a focused survey shall be performed during the species’ active flight period for Crotch’s bumblebee and peak blooming period of nectar and pollen sources (May 1 through July 31). The Crotch’s bumblebee survey shall be conducted on foot and shall encompass the entirety of a project site and focus on areas that allow for the highest probability of detection, such as high abundance nectar or pollen sources and rodent burrows that may be used for breeding and nesting. If Crotch’s bumblebee is determined to be present, the project proponent shall map the locations of the observed bumblebee, areas of abundant nectar or pollen sources, and any active nesting sites. A report summarizing the results of the habitat assessment and focused survey (if required) shall be prepared by the qualified biologist and shall be submitted to the City prior to the commencement of construction activities. Further, consultation with the CDFW will be necessary in the event Crotch’s bumblebee was observed within a project site and an Incidental Take Permit, in accordance with the California Endangered Species Act, may be required prior to initiating any ground disturbance on the site. If Crotch’s bumble bees are not listed and no longer candidates for listing at the time of project implementation, this mitigation measure would not be required.

4.2.5 Cultural Resources – Impact CUL-1
Development facilitated by the project could adversely affect previously unidentified historic-period resources. Impacts to historic-period resources would be less than significant with mitigation.

Explanation
Mitigation Measure CUL-1 would ensure a historical resource evaluation is conducted for sites with age-eligible resources within the Planning Area and require measures to reduce impacts to historical resources to less than significant.

Mitigation Measures
Pursuant to CEQA Guidelines Section 15091, the following mitigation measure have been included in a MMRP that is to be adopted concurrently with these findings. 625
City of American Canyon
American Canyon 2040 General Plan Update
16 CUL-1 Historical Built Environment
Prior to project approval, the applicant shall submit a report to the City that identifies any historicage features (i.e., structures over 45 years of age) proposed to be altered or demolished. If historical-age features are present, the applicant shall submit a historical resources evaluation to the City prepared in areas that contains buildings, structures, objects, sites, landscape/site plans, or other features that are 45 years of age or older, by a qualified architectural historian or historian who meets the Secretary of the Interior’s Professional Qualifications Standards (PQS) in architectural history or history (36 CFR Part 61). The evaluation shall include an intensive-level evaluation, in accordance with the guidelines and best practices meeting the State Office of Historic Preservation guidelines. All evaluated properties shall be documented on Department of Parks and Recreation Series 523 Forms. The report shall be submitted to the City for review and approval.

The applicant shall submit a report to the City that identifies and specifies the treatment of character-defining features and construction activities, and demonstrates how the project complies with the Standards and avoids the substantial adverse change in the significance of the historical resource as defined by CEQA Guidelines Section 15064.5(b). The report shall be prepared by an architectural historian or historical architect meeting the PQS as defined by 36 CFR Part 61 and provided to the City for review and concurrence prior to project approval.

4.2.6 Cultural Resources – Impact CUL-2
Development facilitated by the project could adversely affect previously unidentified archaeological resources. Impacts would be less than significant with mitigation.

Explanation
Mitigation Measures CUL-2 and CUL-3 would reduce potential impacts to a less than significant level by requiring the identification and evaluation of any archaeological resources that may be present prior to construction and by providing steps for the evaluation and protection of unanticipated finds encountered during construction.

Mitigation Measures
Pursuant to CEQA Guidelines Section 15091, the following mitigation measure has been included in a MMRP that is to be adopted concurrently with these findings.

CUL-2 Archaeological Resources Assessment
Prior to project approval of a project that involves ground disturbance activities (that may include but are not limited to, pavement removal, potholing, grubbing, tree removal, and grading), the applicant shall submit to the City an archaeological resources assessment prepared by a qualified 626
Findings of Fact
Findings of Fact and Statement of Overriding Considerations 17 archaeologist who meets the Secretary of the Interior’s Professional Qualifications Standards in either prehistoric or historic archaeology. Assessments shall include a CHRIS records search at the NWIC and a SLF Search from the NAHC. The records searches shall characterize the results of previous cultural resource surveys and disclose any cultural resources that have been recorded and/or evaluated in and around the development site. A qualified professional shall conduct a Phase I pedestrian survey for those projects that include undeveloped areas to locate any surface cultural materials.

If the Phase I archaeological survey identifies resources that may be affected, the applicant shall also conduct Phase II testing and evaluation. If resources are determined significant or unique through Phase II testing and site avoidance is not possible, the qualified professional shall identify appropriate site-specific mitigation measures in the Phase II evaluation. These measures may include, but would not be limited to, a Phase III data recovery program, avoidance, or other appropriate actions to be determined by a qualified archaeologist. If significant archaeological resources cannot be avoided, impacts may be reduced to less than significant level by filling on top of the sites rather than cutting into the cultural deposits. Alternatively, and/or in addition, a data collection program may be warranted, including mapping the location of artifacts, surface collection of artifacts, or excavation of the cultural deposit, to characterize the nature of the buried portions of sites. Curation of the excavated artifacts or samples would occur as specified by the archaeologist.

The City shall review and approve the archaeological resources assessment prior to project approval.

CUL-3 Unanticipated Discoveries
For projects whose Phase I archaeological survey identifies archaeological resources that may be affected, the applicant shall retain a qualified cultural resource specialist to monitor construction activities that involve ground-disturbing activities greater than 12 inches in depth and occur within 60 feet of a potentially significant cultural resource. If archaeological resources are encountered during ground-disturbing activities, work in the immediate area must halt and an archaeologist meeting the Secretary of the Interior’s Professional Qualifications Standards for Archaeology should be contacted immediately to evaluate the find. If necessary, the evaluation may require preparation of a treatment plan and archaeological testing for CRHR eligibility. If the discovery proves to be significant under CEQA and cannot be avoided by the project, additional work, such as excavating the cultural deposit to fully characterize its extent and collecting and curating artifacts may be warranted to mitigate any significant impacts to cultural resources. If archaeological resources of Native American origin are identified during construction, a qualified archaeologist will consult with the City to begin Native American consultation procedures. Periodic reports of the find and subsequent evaluations shall be submitted to the City during construction.

4.2.7 Cultural Resources – Impact CUL-3
Development facilitated by the project could result in damage to or destruction of human burials.

Impacts would be less than significant through adherence to existing regulations and with mitigation.

Finding
Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effects as identified in the Final EIR (CEQA 627
City of American Canyon
American Canyon 2040 General Plan Update
18 Guidelines Section 15091[a][1]). Implementation of Mitigation Measure CUL-4 would reduce potential impacts related to human remains to a less than significant level.

Explanation
Mitigation Measure CUL-4 would reduce potential impacts on human remains to a less than significant level by requiring the implementation of the appropriate protocols in the event of discovery of human remains.

Mitigation Measures
Pursuant to CEQA Guidelines Section 15091, the following mitigation measure has been included in an MMRP that is to be adopted concurrently with these findings.

CUL-4 Human Remains
In the event of an accidental discovery or recognition of any human remains, CEQA Guidelines Section 15064.5, Health and Safety Code Section 7050.5, and Public Resources Code Sections 5097.94 and Section 5097.98 shall be followed. If during construction, there is accidental discovery or recognition of any human remains, the following steps shall be taken:

1. There shall be no further excavation or disturbance within 100 feet of the remains until the County Coroner is contacted to determine whether the remains are Native American and if an investigation of the cause of death is required. If the Coroner determines the remains to be Native American, the Coroner shall contact the Native American Heritage Commission (NAHC) within 24 hours, and the NAHC shall identify the person or persons it believes to be the Most Likely Descendant (MLD) of the deceased Native American. The MLD may make recommendations to the landowner or the person responsible for the excavation work within 48 hours, for means of treating or disposing of, with appropriate dignity, the human remains, and any associated grave goods as provided in Public Resources Code Section 5097.98.

2. Where the following conditions occur, the landowner or authorized representative shall rebury the Native American human remains and associated grave goods with appropriate dignity either in accordance with the recommendations of the MLD or on the project site in a location not subject to further subsurface disturbance:
 The NAHC is unable to identify an MLD or the MLD failed to make a recommendation within 48 hours after being notified by the commission.
 The descendant identified fails to make a recommendation.  The landowner or authorized representative rejects the recommendation of the descendant, and mediation by the NAHC fails to provide measures acceptable to the landowner.

Additionally, California Public Resources Code Section 15064.5 requires the following relative to Native American Remains:
 When an initial study identifies the existence of, or the probable likelihood of, Native American Remains within a project, a lead agency shall work with the appropriate Native Americans as identified by the NAHC as provided in Public Resources Code Section 5097.98. The applicant may each develop a plan with respect to their respective individual development proposals for treating or disposing of, with appropriate dignity, the human remains, and any items associated with Native American Burials with the appropriate Native Americans as identified by the NAHC. 628

4.2.8 Noise – Impact NOI-2
Construction of development facilitated by the project would temporarily generate groundborne vibration and noise, potentially affecting nearby land uses. This impact would be less than significant with mitigation. Operation of development facilitated by the project would not result in substantial groundborne vibration and noise and this impact would be less than significant.

Explanation
Implementation of Mitigation Measure requires preparation of groundborne noise and vibration analysis prior to construction and use of alternative construction equipment and construction monitoring if vibration levels would exceed Federal Transit Administration thresholds. NOI-3 Construction vibration impacts would be less than significant with implementation of Mitigation Measure NOI-3, which requires measures to reduce construction vibration.

Mitigation Measures
Pursuant to CEQA Guidelines Section 15091, the following mitigation measure has been included in a MMRP that is to be adopted concurrently with these findings.

NOI-3 Construction Vibration Control Plan
Prior to issuance of a building permit for a project that includes the following, the project applicant shall prepare a groundborne noise and vibration analysis to assess and mitigate potential noise and vibration impacts related to these construction activities:
 Pile driving within:
 135 feet of fragile structures such as historical resources;  100 feet of non-engineered timber and masonry buildings (e.g., most residential buildings); or
 75 feet of engineered concrete and masonry (no plaster);  A vibratory roller within:
 40 feet of fragile historical resources; or
 25 feet of any other structure
 A dozer or other large earthmoving equipment within:
 20 feet for a fragile historical structure; or
 15 feet of any other structure
The noise and vibration analysis shall be conducted by a qualified and experienced acoustical consultant or engineer. The vibration levels shall not exceed FTA architectural damage thresholds (e.g., 0.12 in/sec PPV for fragile or historical resources, 0.2 in/sec PPV for non-engineered timber 629
City of American Canyon
American Canyon 2040 General Plan Update
20 and masonry buildings, and 0.3 in/sec PPV for engineered concrete and masonry). If vibration levels would exceed this threshold, alternative uses such as drilling piles as opposed to pile driving, static rollers as opposed to vibratory rollers, and lower horsepower earthmoving equipment shall be used.

If necessary, construction vibration monitoring shall be conducted to ensure FTA vibration thresholds are not exceeded.

4.2.9 Paleontolgoical Resources – Impact PAL-1
The project has the potential to result in impacts to paleontological resources. Impacts would be less than significant with mitigation incorporated.

Explanation
Mitigation Measure PAL-1 requires a Qualified Professional Paleontologist to determine a project’s potential to disturb paleontological resources for projects in an area underlain by high or undetermined geological sensitivities. The project applicant must implement the Qualified Professional Paleontologist’s recommendations. Implementation of Mitigation Measure PAL-1 would reduce adverse effects to paleontological resources and impacts would be less than significant with mitigation.

Mitigation Measures
Pursuant to CEQA Guidelines Section 15091, the following mitigation measures have been included in a MMRP that is to be adopted concurrently with these findings.

PAL-1 Retention of Qualified Professional Paleontologist Prior to submittal of a discretionary development application in areas underlain by high or undetermined sensitivity geologic units (i.e., Pleistocene alluvial fan deposits; Markley Sandstone; Jameson Shale Member of Markley Sandstone; Domengine Sandstone; and sandstone and shale of the Great Valley Complex), the City shall require a Qualified Professional Paleontologist [as defined by the Society of Vertebrate Paleontology (SVP) (2010)] be retained to determine the project’s potential to significantly impact paleontological resources according to SVP (2010) standards. If necessary, the Qualified Professional Paleontologist shall recommend mitigation measures to reduce potential impacts to paleontological resources to a less than significant level. The City shall review and approve the Qualified Professional Paleontologist’s findings and recommendations. All recommendations shall be incorporated into the project plans prior to issuance of a grading permit.

4.2.10 Wildfire – Impact W-2
The project could expose people and structures to wildfire risk; however, wildfire risks would be reduced with mitigation and impacts would be less than significant. 630
Findings of Fact
Findings of Fact and Statement of Overriding Considerations 21 Finding
Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effects as identified in the Final EIR (CEQA Guidelines Section 15091[a][1]). Implementation of Mitigation Measures WF-1 and WF-2 would reduce potential impacts related to the risk of loss of structures and the risk of injury or death due to wildfires to a less than significant level.

Explanation
With implementation of Mitigation Measures WF-1 and WF-2 the risk of loss of structures and the risk of injury or death due to wildfires would be reduced. These measures would make structures more fire resistant and less vulnerable to loss in the event of a wildfire. These mitigation measures would also reduce the potential for construction to inadvertently ignite a wildfire and require the use of fire-resistant native vegetation. Given the risk of wildfires in the Planning Area and that mitigation would be implemented to reduce the risk, impacts would be less than significant.

Mitigation Measure
WF-1 Wildfire Risk Reduction During Construction
For projects located in proximity to agricultural or undeveloped areas (including hillside areas) with flammable vegetation, prior to issuance of a grading or building permit, whichever occurs first, the applicant shall submit documentation that they will implement the following measures to reduce risk of loss, injury, or death from wildfire during construction:

1. Construction equipment powered by internal combustion engines shall be equipped with spark arresters. The spark arresters shall be maintained pursuant to manufacturer recommendations to ensure adequate performance.

2. Certain project construction activities with potential to ignite wildfires during red-flag warnings issued by the National Weather Service for the project site location shall be prohibited. Example activities that shall be prohibited during red-flag warnings include welding and grinding outside of enclosed buildings, mowing, chain sawing, chipping, and the use of any equipment with the potential to introduce sparks.

3. Fire extinguishers shall be required to be onsite during construction. Construction vehicles shall be equipped with at least one (1) functioning fire extinguisher and one (1) shovel or McLeod firefighting tool. Heavy machinery or equipment (e.g., tractors, grinders, tree chippers, excavators, bulldozers) shall be equipped with one (1) shovel, McLeod firefighting tool, or Pulaski; one (1) functioning fire extinguisher; and at least one 5-gallon backpack pump or larger capacity water (or CAFS) pump/delivery system. Fire extinguishers shall be maintained to function according to manufacturer specifications. Construction personnel shall receive training on the proper methods of using a fire extinguisher.

WF-2 Fire Resistant Vegetation and Landscaping
For projects located in proximity to agricultural or undeveloped areas (including hillside areas) with flammable vegetation, prior to issuance of a building permit for development located within or adjacent to a VHFHSZ, the applicant shall submit landscape plans prepared by a registered Landscape Architect that are consistent with applicable Building and Fire Codes. 631

22 Findings for Significant and Unavoidable Effects
Public Resources Code 21081 and 21081.5, and CEQA Guidelines Section 15093, require that the City of American Canyon balance the economic, legal, social, technological, or other benefits of a proposed project against its unavoidable environmental effects when determining to approve a project. If specific economic, legal, social, technological, or other benefits outweigh the unavoidable adverse environmental effects, the adverse effects may be considered “acceptable.” The Final EIR identifies the following significant and unavoidable impacts that would be caused by implementation of the project: impacts associated with GHG emissions (impacts related to conflicts with state GHG reduction goals), noise (impacts related to construction noise and operational traffic noise), and transportation (impacts related to VMT). The following findings and statement of overriding considerations outline the specific reasons to support the City of American Canyon Community Development Department recommendation for approval.

4.3.1 Greenhouse Gas Emissions – Impact GHG 1
Development facilitated by the project would make progress towards achieving state goals but would not necessarily meet state 2030 or 2045 goals. Mitigation Measures GHG-1 through GHG-3 would require implementation of CEQA GHG thresholds and a Climate Action Plan (CAP); however, development facilitated by the project would not meet the 2030 or 2045 goals until the CAP is updated and adopted. This impact would be significant and unavoidable.

Mitigation Measures
GHG-1 Construction GHG BMPs
Prior to the issuance of any grading permits, the project applicant shall provide the City of American Canyon with documentation (e.g., site plans) demonstrating implementation of construction Best Management Practices (BMPs). Measures may include but are not limited to:
 At least 15 percent of the construction fleet for each project phase shall be alternatively fueled or electric.
 At least 10 percent of building materials used for project construction shall be sourced from local suppliers.
 At least 65 percent of construction and demolition waste materials shall be recycled or reused.  At least one contractor that has a business location in American Canyon shall be contracted for project construction.
 All construction contracts shall include language that requires all off-road equipment with a power rating below 19 kilowatts (e.g., plate compactors, pressure washers) using during construction be electrically powered.
 Architectural coatings used for project construction shall be “Low-VOC,” containing no greater than 50 grams of volatile organic compounds (VOC) per liter of product.  Project construction shall prohibit the use of generators and shall establish grid power connection to electrical equipment needs.
 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 632
Findings of Fact
Findings of Fact and Statement of Overriding Considerations 23 Measure [ATCM] Title 13, Section 2485 of California Code of Regulations). Clear signage regarding idling restrictions 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.  The prime construction contractor shall post a publicly visible sign with their telephone number and contractor to contact. The construction contractor shall take corrective action within 48 hours. The BAAQMD’s phone number shall also be identified and visible to ensure compliance with applicable regulations.

GHG-2 Adopt and Implement a CEQA GHG Emissions Threshold The City shall include and implement a new 2040 General Plan policy under the Environment Element to prepare, adopt, and implement a CEQA GHG Emissions threshold of significance. The City shall adopt the CEQA GHG Emissions threshold of significance by the end of 2025 for use in future CEQA GHG emissions analyses through 2030. In addition, upon completion of future CAP updates and as necessary, the City shall update the CEQA GHG Emissions threshold of significance and American Canyon CEQA GHG Checklist to be consistent with each CAP update.

GHG-3 Adopt American Canyon CAP to Meet the State’s 2030 and 2045 GHG Emissions Goals
The City shall draft and adopt the American Canyon qualified CAP by the end of 2025 to outline how American Canyon will meet the State’s 2030 goal of 40 percent below 1990 emissions levels and 2045 goal of carbon neutrality. Implementation measures in the updated qualified CAP to achieve the 2030 and 2045 goals may include, but are not limited to, the following: Develop and adopt Zero Net Energy requirements for new and remodeled residential and non-residential development;  Develop and adopt a building electrification ordinance for existing and proposed structures;  Expand charging infrastructure and parking for electric vehicles;  Implement carbon sequestration by expanding the urban forest, participating in soil-based or compost application sequestration initiatives, supporting regional open space protection, and/or incentivizing rooftop gardens; and
 Implement policies and measures included in the California 2022 Climate Change Scoping Plan, such as mobile source strategies for increasing clean transit options and zero emissions vehicles by providing electric vehicle charging stations.

Finding and Rationale
Implementation of Mitigation Measure GHG-1 would ensure that construction related GHG impacts would be less than significant. Implementation of Mitigation Measures GHG-2 and GHG-3 would ensure that development facilitated by the project after 2026 would be consistent with State emissions goals. However, individual projects that may occur prior to 2026 would not be guaranteed to be consistent with State emissions goals, nor are exact emissions reductions known at the time of adoption of the 2040 General Plan. Until the CEQA GHG thresholds and the CAP are prepared and adopted, implementation of the project would not be consistent with BAAQMD GHG thresholds nor would it be consistent with State GHG reduction plans. Therefore, the project’s impact related to GHG emissions would be significant and unavoidable.

24 4.3.2 Noise – Impact NOI-1
Construction of development facilitated by the project would temporarily increase noise levels, potentially affecting nearby noise-sensitive land uses. Development facilitated by the project would also introduce new noise sources and contribute to increases in operational noise. The continued regulation of noise, consistent with the City Municipal Code and implementation of proposed policies in the 2040 General Plan would minimize impacts to adjacent land uses. However, construction and operational traffic noise could exceed standards even after implementation of mitigation. This impact would be significant and unavoidable.

Mitigation Measure
NOI-1 Conduct Construction Noise Analysis
The City shall review future developments within 1,000 feet of a sensitive receiver, and where applicable, require the following feasible measures as standard conditions of approval to reduce construction noise levels below a level of significance:
 Mufflers. During excavation and grading construction phases, all construction equipment, fixed or mobile, shall be operated with closed engine doors and shall be equipped with properly operating and maintained mufflers consistent with manufacturers’ standards.  Stationary Equipment. All stationary construction equipment shall be placed so that emitted noise is directed away from the nearest sensitive receivers.  Equipment Staging Areas. Equipment staging shall be located in areas that will create the greatest distance feasible between construction-related noise sources and noise sensitive receivers.
 Smart Back-up Alarms. Mobile construction equipment shall have smart back-up alarms that automatically adjust the sound level of the alarm in response to ambient noise levels.

Alternatively, back-up alarms shall be disabled and replaced with human spotters to ensure safety when mobile construction equipment is moving in the reverse direction in compliance with applicable safety laws and regulations.
 Electrically-Powered Tools and Facilities. Electrical power shall be used to run air compressors and similar power tools and to power any temporary structures, such as construction trailers or caretaker facilities, where feasible.
 Noise Disturbance Coordinator. The project applicant shall designate a “noise disturbance coordinator” responsible for responding to any local complaints about construction noise. The disturbance coordinator shall determine the cause of any noise complaint and shall require that reasonable measures be implemented to correct the problem. A telephone number for the disturbance coordinator and the City shall be posted at the construction site.  Temporary Noise Barriers. Erect temporary noise barriers, where feasible, when construction noise is predicted to exceed the City’s construction standards and when the anticipated construction duration is greater than is typical (e.g., two years or greater). Temporary noise barriers shall be constructed with solid materials (e.g., wood) with a density of at least 1.5 pounds per square foot with no gaps from the ground to the top of the barrier. If a sound blanket is used, barriers shall be constructed with solid material with a density of at least 1 pound per square foot with no gaps from the ground to the top of the barrier and be lined on the construction side with acoustical blanket, curtain or equivalent absorptive material rated sound transmission class (STC) 32 or higher.
634
Findings of Fact
Findings of Fact and Statement of Overriding Considerations 25 NOI-2 Implement Roadway Vehicle Noise Reduction Measures The City shall install “quiet pavement” roadway improvements, such as rubberized asphalt or opengrade asphalt concrete overlays along impacted roadway segments (American Canyon Road west of I-80 and Newell Drive north of American Canyon Road). The program may be funded by “fair share” developer contributions for proposed projects along impacted roadways to pay for the “quiet pavement” roadway improvements.

Finding and Rationale
Construction of individual projects facilitated by the project would temporarily increase noise levels, potentially affecting nearby noise-sensitive land uses. Development facilitated by the project would also introduce new noise sources and contribute to increases in operational noise. Construction and operational traffic noise could exceed standards. The continued regulation of noise, consistent with the City Municipal Code and implementation of proposed policies in the 2040 General Plan would minimize impacts to adjacent land uses. However, construction noise impacts would be significant and unavoidable even with implementation of Mitigation Measure NOI-1. Operational traffic noise impact would be significant and unavoidable even with implementation of Mitigation Measure NOI-2.

4.3.3 Transportation – Impact TRA-2
The future (2040) Citywide rate of Residential VMT per Capita with the proposed 2040 General Plan would be higher than the significance threshold. The project would therefore conflict with or be inconsistent with CEQA Guidelines Section 15064.3(b) and impacts would be significant.

Mitigation Measure
There are no feasible mitigation measures beyond policies included in the Mobility Element of the General Plan.

Finding and Rationale
The 2040 General Plan includes policies which would reduce VMT. However, because there is no specific mitigation to reduce VMT per resident and the General Plan policies cannot realistically enforce mitigation programs or policies that might reduce VMT below the threshold, impacts would remain significant and unavoidable.

American Canyon 2040 General Plan Update
26 5 Project Alternatives
Section 15126.6 of the CEQA Guidelines states the following:

An EIR shall describe a range of reasonable alternatives to the project, or to the location of the project, which would feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project, and evaluate the comparative merits of the alternatives. An EIR need not consider every conceivable alternative to a project.

Rather it must consider a reasonable range of potentially feasible alternatives that will foster informed decision making and public participation. An EIR is not required to consider alternatives which are infeasible. The lead agency is responsible for selecting a range of project alternatives for examination and must publicly disclose its reasoning for selecting those alternatives. There is no ironclad rule governing the nature or scope of the alternatives to be discussed other than the rule of reason.

As described in Section 4.3, Findings for Significant and Unavoidable Effects, above, the City of American Canyon has determined that, even after the adoption of all feasible mitigation measures, the project would still cause one or more significant environmental impacts that cannot be avoided or lessened to below a level of significance. Therefore, the City of American Canyon must determine if there is a project alternative that is both environmentally superior and feasible. An alternative may be “infeasible” if it fails to achieve the most basic project objectives identified within the EIR.

Further, “feasibility” under CEQA encompasses the desirability of the project “based on a reasonable balancing of the relevant economic, environmental, social, and technological factors” of a project (City of Del Mar v. City of San Diego [1982], 133 Cal.App.3d at p. 417; see also Sequoyah Hills Homeowners Assn. v. City of Oakland [1993], 23 Cal.App.4th at p. 715).

The Final EIR identifies the following significant and unavoidable impacts that would be caused by implementation of the project: impacts associated with GHG emissions (impacts related to conflicts with state GHG reduction goals), noise (impacts related to construction noise and operational traffic noise), and transportation (impacts related to VMT). The alternatives analyzed in the Final EIR and described below are therefore discussed below in terms of their potential ability to avoid or reduce these impacts.

Alternative 1: No Project Alternative
The No Project Alternative represents the continuation of existing zoning and General Plan designations within the City. Assuming a maximum buildout scenario, buildout for the No Project Alternative would allow for 3,204 housing units and approximately 5.7 million square feet of additional non-residential land uses. Compared to the proposed project, the No Project Alternative would not include updated General Plan policies.

Finding
The No Project Alternative would have a significant and unavoidable effect on GHG emissions and would not implement Mitigation Measures GHG-2 or GHG-3 which would require the adoption of a GHG threshold and CAP to meet the State’s 2030 and 2045 GHG emissions goals. The No Project Alternative would not implement policies in the 2040 General Plan Update, including policies related to noise compatibility in site design (policies S-8.1, S-8.2, and S-8.3), which would result in 636
Project Alternatives
Findings of Fact and Statement of Overriding Considerations 27 greater stationary source noise impacts than the proposed project. The No Project Alternative would result in an increase in VMT compared to the proposed project because the No Project Alternative would not implement 2040 General Plan Update policies MOB-1.17 or MOB-6.1 that support VMT reduction. Therefore, the No Project Alternative would result in worse significant and unavoidable traffic noise impacts and VMT impacts compared to the proposed project. In addition, the No Project Alternative would not reduce the impact of any other issue area analyzed within the Final EIR.

The No Project Alternative would not accomplish the primary objective of the project, which is to update the existing American Canyon General Plan for it to be compliant with State law. In addition, the No Project Alternative would not include the updated 2040 General Plan policies and programs pertaining to community development, preservation of natural resources, sustainability, and improvement of American Canyon’s circulation network.

The No Project Alternative would not reduce the proposed project’s environmental impacts, would not fulfill any project objectives, and would be inconsistent with State law. Therefore, the City rejects the No Project Alternative as infeasible because it would not achieve the project objectives.

Alternative 2: Watson Ranch Natural Alternative
Alternative 2 would assume maximum density on the Watson Ranch property which would result in an additional 596 dwelling units. Alternative 2 assumes that the General Plan would be updated like for the proposed project, (including the updated policies that make the General Plan consistent with State law). Overall Alternative 2 assumes increased residential densities when compared to the proposed project (3,975 total units). In addition, because Alternative 2 would maintain the same designations as the General Plans for non-residential spaces, the buildout of non-residential space would be the same as the proposed project. Buildout under Alternative 2, assuming a maximum buildout scenario, would allow for 3,975 housing units and approximately 5,704,000 square feet of additional non-residential land uses.

Finding
Alternative 2 would meet the objectives of the proposed project as it would increase residential buildout while accommodating the same amount of non-residential buildout as the proposed project. However, due to the increased residential buildout, Alternative 2 would increase GHG emissions, construction noise and traffic noise, and VMT per capita in comparison to the proposed project and these impacts would remain significant and unavoidable, similar to the proposed project. In addition, Alternative 2 would result in similar, though slightly increased, impacts to aesthetics, air quality, biological resources, cultural resources, paleontological resources, population and housing, public services and recreation, tribal cultural resources, and utilities and service systems due to the increased residential buildout.

Although Alternative 2 would fulfill the project objectives, due to the increased environmental impacts associated with Alternative 2 in comparison to the proposed project, Alternative 2 is less 637
City of American Canyon
American Canyon 2040 General Plan Update
28 desirable than the proposed project. Therefore, the City rejects Alternative 2 as undesirable as it fails to reduce any of the proposed project’s environmental effects.

Alternative 3: Limited Growth Alternative
Alternative 3 assumes that the General Plan would be updated to include the updated policies that make the General Plan consistent with State law. However, under Alternative 3, buildout would be limited to pipeline projects (i.e., project already identified by the City to be constructed in the future) and other projects that have already been approved or for which General Plan amendments have already been approved (e.g., Watson Ranch Specific Plan, Broadway District Specific Plan). As such, buildout would be reduced in the following ways:
 Residential buildout would be reduced by 408 dwelling units compared to the proposed project because: (1) the land use designations for the two NVUSD would remain as Recreation and Public and would not be changed to Residential Medium, reducing the number of residential units by 175 units and (2) the buildout identified in the City’s Traffic Impact Fee (TIF) Nexus Study would be reduced by 233 residential units.
 Non-residential land use area would be reduced by 65,000 square feet based on the buildout identified in the City’s TIF Nexus Study.

Overall Alternative 3 assumes decreased residential densities (2,971 units total) when compared to the proposed project (3,379 total units), as well as decreased non-residential area (5,639,000 square feet) when compared to the proposed project (5,704,000 square feet).

Finding
Alternative 3 would require the City to limit growth to those projects that have already been approved by the City or identified as planned projects. Alternative 3 would not reduce the proposed project’s significant and unavoidable impact related to GHG emissions, construction noise, and traffic noise. However, Alternative 3’s reduced buildout would result in reduced construction impacts related to air quality construction emissions, biological resources, cultural resources, temporary noise, tribal cultural resources, and paleontological resources due to less area being affected (i.e., excavated, graded, etc.) and due to less use of construction equipment. In addition, Alternative 3 would result in reduced aesthetic impacts because there would be fewer buildings; less air quality emissions because there would be less overall VMT; less operational noise because there would be less traffic and fewer HVAC units; and less demand for public services, recreation, and utilities.

Alternative 3 would require the City to limit growth to those projects that have already been approved by the City or identified as planned projects. Alternative 3 would reduce the residential and non-residential buildout; therefore, compared to the proposed project, this alternative would reduce the ability for the City to meet its vision of accommodating a residential population with a range of uses; creating a center of employment and commerce; and capturing visitors to the Napa Valley. While Alternative 3 would meet the objective of updating the General Plan so that it’s consistent with State law, this alternative would not help meet the vision of American Canyon to the 638
Project Alternatives

The findings for the proposed project set forth in this document and the overriding social, economic and other considerations set forth in the Statement of Overriding Considerations provide support for selection of the proposed project and the elimination of this alternative from further consideration.

30 6 Statement of Overriding Considerations
As described in the Final EIR for the American Canyon 2040 General Plan Update, the EIR finds that all potential impacts from adoption of the project and from physical changes that could potentially occur due to adoption of the project can be feasibly mitigated to a level that is less than significant, with the following exceptions: Impact GHG-1, conflicts with applicable plan, policy, or regulation adopted for the purpose of reducing GHG emissions; Impact NOI-1, construction noise and operational traffic noise impacts from new development; and Impact TRA-2, conflicts with CEQA Guidelines Section 15064.3(b).

In accordance with CEQA Guidelines Section 15093, the City Council has, in determining whether to approve the project, balanced the economic, legal, social, technological, and other benefits of the project against the potentially unavoidable environmental impacts, and has found that the benefits of the project outweigh the potentially unavoidable environmental effects, for the reasons set forth below. The following statements specify the reasons why, in the City Council’s judgement, the benefits of the project outweigh any of the significant and unavoidable consequences described in the EIR. The City Council also finds that any one of the following reasons cited below is sufficient to justify approval of the project. Thus, even if it were to be determined that not every reason cited below is supported by substantial evidence, the City Council determines that each individual reason is sufficient justification of approval of the project. The substantial evidence supporting the City Council’s findings and the benefits described below can be found in the record of proceedings.  The adoption of the project would update outdated policies in a manner that meets current State legal requirements for General Plans.
 The adoption of the project would set forth a plan for ensuring the residents of American Canyon are accommodated with a sufficient range of uses to support the needs of residents (including a mix of housing types, commercial services, entertainment, employment, recreation, education, health, religious, cultural facilities, transportation services, and open space).  The adoption of the project would set forth a plan for the City to be a center of employment and commerce for regional, as well as local residents.
 The adoption of the project would set forth a plan to capture visitors to the Napa Valley by providing uses which capitalize on the unique environmental setting of the foothills, river valleys, and agriculture.
 The adoption of the project would implement policies designed to support the enhancement of utility infrastructure to sustain households, businesses, and future population increases and employment growth in American Canyon.
 The adoption of the project would implement policies designed to maintain a safe and efficient transportation system that includes roadway, transit, bicycle, pedestrian, rail transport, and aviation.
 The adoption of the project would implement strategies for preserving and enhancing human and natural environments, including sensitive habitats, waterways, cultural resources, open space, parks, and scenic areas.
 The adoption of the project would implement policies designed to achieve GHG emissions reduction targets set forth in Executive Order B-55-18. 640
Statement of Overriding Considerations
Findings of Fact and Statement of Overriding Considerations 31  The adoption of the project would implement strategies for providing a safe community through public safety services, resilient infrastructure, public awareness, preparedness, and action plans for both human-caused and natural disasters.
 The adoption of the project would establish a basis for judging whether specific development proposals and public projects are in harmony with the General Plan policies and standards.

Any one of these reasons is sufficient to support adoption of the American Canyon 2040 General Plan Update, and to outweigh the identified significant and unavoidable environmental effects that might occur due to adoption of the project. In light of the benefits to the City and the local community identified above, pursuant to CEQA Guidelines Section 15903, the City Council finds that these overriding considerations, as identified in conjunction with the environmental review of impacts stemming from adoption of the American Canyon 2040 General Plan Update, outweigh the potentially significant and unavoidable environmental impacts identified in the Final EIR, rendering those impacts acceptable under the circumstances.

Public Review Draft Introduction | March 2025 | INT-3
Introduction
Purpose and Use of the General Plan
What is a General Plan?
Every city and county in California must have a General Plan, which is the local government’s long-term framework or “constitution” for future growth and development. The General Plan represents the product of extensive community engagement that expresses the community’s vision for its future.

This General Plan is designed to address the issues facing the jurisdiction for the next 20 years. The General Plan typically has four defining features:
• General. A General Plan provides general policy guidance that will be used to direct future land use and resource decisions.
• Comprehensive. A General Plan is comprehensive, covering topics such as land use; housing; economic development; environmental justice; sustainability and resiliency; mobility; public safety; recreation; natural resources; and much more.
• Long-Range. A General Plan provides guidance on reaching a future envisioned 20 or more years in the future. To achieve the vision, a General Plan includes goals, policies, and implementation programs that address both immediate and long-term needs.
• Integrated and Coherent. The goals, policies, and implementation programs in a General Plan present a comprehensive, unified program for development, resource conservation, and other issues that impact the community. A General Plan uses assumptions and projections to assess future demands for housing, employment, and public facilities (e.g., infrastructure). A General Plan has goals, policies, and implementation programs that enable citizens to understand the vision of the General Plan, and landowners, businesses, and industry to be more certain about how the Plan will be implemented.

A General Plan is made up of “elements” that cover mandatory and optional topics important to the community. Eight elements are required to be included in the General Plan by the State. These are: Land Use, Circulation, Housing, Conservation, Open Space, Noise, Safety, and Environmental Justice.

Though the required topics must be addressed in the General Plan, communities can organize their General Plan anyway they choose. 652
INT-4 | Public Review Draft Introduction | March 2025
Communities may also include other optional elements that address issues of local interest, such as Economic Development, Health, or Education.

Zoning is an important implementation tool of the General Plan. Although the General Plan and zoning code designate how land may be developed, they do so in different ways. The General Plan identifies allowable land uses, spatial land use relationships, and general pattern of future development.

Land uses shown on the General Plan diagram will be reflected in the local zoning maps, as required per State law. Zoning refines and implements the General Plan land uses by providing specific development standards such as lot size, building setbacks, and allowable uses. Development must not only meet the specific requirements of the zoning code, but also the broader policies set forth in the General Plan.

The American Canyon General Plan meets the requirements of State law by including required elements and one optional element as described in more detail later in this chapter under “Organization of the General Plan.” Some of the required elements address additional issues of local interest. Each element contains goals and policies that will guide future decisions within the City. They each also identify implementation programs that will be used to ensure the goals and policies in the General Plan are carried out.

The American Canyon Community
American Canyon is located in Southern Napa County close to the worldfamous Napa Valley wine growing region and in close proximity to the San Francisco Bay. Beginning with the McKnight Acres subdivision in the 1940s and the Rancho Del Mar subdivision in the 1950s, American Canyon began a period of initial growth. With McKnight Acres’ 150 residential sites and Rancho Del Mar’s 600 homes, schools, businesses, and the area’s first fire and sewer districts quickly emerged. By 1963 the area supported 27 businesses and was the largest industrial zone in the county. Despite this growth, the area would remain an unincorporated area of Napa County through the 1980s.

In 1991, American Canyon residents overwhelmingly voted to incorporate the City. At the heart of incorporation is the resident’s ability to gain local control over land use and other important decisions that affect their everyday life.

The City operates under a council-manager form of government and is a general law city. The City provides a full range of municipal services including police and fire protection services; construction and maintenance of City 653

1. INTRODUCTION
Public Review Draft Introduction | March 2025 | INT-5
streets, storm drains, bridges and similar infrastructure type assets; park maintenance and community recreation activities; short and long-range community planning; operation of water, wastewater, and recycled water utilities; and more.

Since becoming a City on January 1, 1992, the City has grown to more than 21,000 residents., American Canyon is home to three elementary schools, one middle school and one high school and dozens of businesses. In addition to the tourism related economic benefits of proximity to the Napa Valley, American Canyon benefits tremendously as a wine processing hub. Because of our strategic location at the southern end of Napa County and with easy access to state and interstate highways, American Canyon's industrial district is home to millions of square feet of wine processing, bottling, storage, and shipping space. Demand for space in this area is very high, with very little vacancy and there is new development underway.

Regional Setting
Located 35 miles northeast of San Francisco, the City of American Canyon covers an area approximately 6.5 square miles as shown in Figure INT-1. The City is bounded geographically by the Napa River to the west, the Eastern Foothills of the Sulphur Springs Mountain Range to the east, the City of Vallejo to the south, and the Napa Airport to the north.

American Canyon Boundaries
The General Plan uses several terms to describe the City and planning boundaries, as shown on Figure 2.
• City Limits. The boundary within the incorporated city limits.

American Canyon has land use authority over all land within its city limits.
• Sphere of Influence. The Napa Local Agency Formation Commission (LAFCo) establishes the Sphere of Influence (SOI), which defines the probable physical boundary and service area of a local agency. The SOI includes incorporated and unincorporated areas where the City has or plans to have responsibility to provide public facilities and services.

The City’s SOI was approved by the Napa Local Agency Formation Commission (LAFCo) at the time of incorporation in 1992 and updated in 2003 2015 in association with the Canyon Estates annexation.

Justification: Updated the most recent SOI amendment.
654
INT-6 | Public Review Draft Introduction | March 2025
• City Urban Limit Line. The City Council adopted a 2008 voter-initiated Urban Limit Line (ULL) around the city. This ULL was negotiated with Napa County to be consistent with the county’s general plan and agricultural protection ordinances. The boundary helps preserve agriculture and open spaces, prevent urban sprawl, and implements the planned development of the city. The ULL also fosters sustainable growth and maintains a balance between housing and jobs. According to the initiative, the ULL will expire in 2030. The General Plan extends the existing ULL indefinitely and includes an addition of the Hess/Laird Property northeast of the city’s current ULL.
• General Plan Planning Area. A General Plan, pursuant to State law, must address all areas within the jurisdiction’s Planning Area that bears a physical relationship to the long-term planning of the city. The General Plan Planning Area encompasses the City of American Canyon Water and Sewer Service area. This area includes the City, SOI, ULL, and Extraterritorial Water and Sewer Service area. Unincorporated Napa County has land use authority outside the City limits, within the Extraterritorial Water and Sewer Service area, however, as the Water and Sewer Service provider, the City’s Extraterritorial Water and Sewer has authority over these services. For this reason, the Water and Sewer Service area bears relation to the City’s planning consistent with Gov. Code §65300.

Justification: The revised language is intended to explain the Water and Sewer Service area’s relationship to the General Plan in clearer terms. 655

Public Review Draft Introduction | March 2025 | INT-9
Using the General Plan
The General Plan is an important reference document used by the City Council, Planning Commission, and City staff to make recommendations and decisions with direct or indirect land use implications. It also provides a framework for inter-jurisdictional planning coordination among officials and staff of the City and other Federal, State, and local agencies. City residents, property owners, and businesses use the General Plan for guidance on City policies for geographic areas or to be informed of policies on particular subjects of interest.

As the constitution of development, the General Plan provides the basis for a broad range of development-related regulatory measures and administrative procedures. California planning law requires consistency between the General Plan and implementing programs, such as zoning and subdivision ordinances, capital improvement programs, specific plans, environmental impact procedures, and building and housing codes. The specific roles of the City Council, Planning Commission, and City departments with respect to the approval and use of the General Plan are described below.

City Council
The City Council is the political body which formulates and implements policies in American Canyon. It is the City Council, through its decision-making authority, that affirms the policy direction and priorities contained within this General Plan. The City Council is responsible for adoption of the General Plan, as well as the regulations, capital improvement programs, and financing mechanisms that implement the General Plan.

Planning Commission
The Planning Commission is a 5-member body responsible for offering insights into the General Plan policies, conducting public hearings on the General Plan and Zoning Code modifications, considering public input on development applications and policy changes, and making recommendations to the City Council on these matters. After the General Plan is adopted, the Planning Commission through findings included in the administrative record, verifies that all subsequent land use ordinances, policies, guidelines, and development applications are consistent with the goals, objectives, and policies in the General Plan.
658
INT-10 | Public Review Draft Introduction | March 2025
Parks and Community Services Commission
The Parks and Community Services Commission is a 5-member body responsible for advising the City Council on matters pertaining to park development, park and recreation facility use issues, recreation programming and related issues.

Open Space, Active Transportation, and Sustainability Commission The Open Space, Active Transportation, and Sustainability Commission is a 5- member body responsible for advising the City Council on open space, active transportation, and sustainability efforts in and around American Canyon.

City Departments
The General Plan is a resource for all City services and provides an internally consistent checkpoint for assessing alternatives for the City’s future. For this reason, all City departments use the General Plan for policy guidance as it pertains to their operations, service delivery, and planning for future capital projects and potential service level changes. The City’s planning staff ensure that the General Plan is implemented on a day-to-day basis so that appropriate land uses are proposed in the proper locations, appropriate levels of service are provided, proposed land uses conform to development regulations, and the environment has been adequately protected.

Preparing the General Plan
In early 2020, the City kicked off the General Plan Update process. This Update ensures the City grows according to current community needs and priorities.

New issues, such as community health and climate change, housing, shared mobility, and online shopping, is also included in the updated General Plan.

The update process involved multiple opportunities for the public to engage in the development of the Plan (see Community Engagement section below).

Community Engagement
The General Plan was shaped through robust public engagement program that provided an opportunity for all community members to be involved in the General Plan update process. The City gathered community input through the following methods:

1. In-person and virtual community workshops;
659

1. INTRODUCTION
Public Review Draft Introduction | March 2025 | INT-11

2. General Plan Update website –
www.cityofamericancanyon.org/government/communitydevelopment/planning-zoning/general-plan-update;

3. eBlasts;

4. Circulation Element Advisory Committee meetings;

5. Education and Lifelong Learning Element Advisory Committee meetings;

6. Parks and Recreation Element Working Group meetings; and

7. Planning Commission and City Council meetings, study sessions, and public hearings.

Community Workshops
The update process involved multiple opportunities for the public to engage in the development of the 2040 General Plan. The City gathered community input through the following methods:
• On February 18, 2020, the City held their annual State of the City at the Boys and Girls Club Clubhouse. The event led with a presentation and was followed by an open house to discuss the General Plan Update. The purpose of the open house was to provide an overview of the General Plan Update, relay opportunities to get involved in the process, collect input on issues and opportunities that should be addressed through the Plan, and receive initial feedback on a citywide vision for American Canyon.
• On April 13 and 27, 2022, the City hosted (via Zoom) two, separate, yet identical workshops. The purpose of this workshop was to introduce the Housing Element and new State requirements, as well as an opportunity for the public to provide comments on housing concerns in the community.

General Plan Update Website
To help expand the outreach efforts of the General Plan, this project included a project website (www.cityofamericancanyon.org/government/communitydevelopment/planning-zoning/general-plan-update) to provide information on the process including information on the General Plan, meeting dates and locations, and related documents. The City used regular updates to the project website throughout the update process to keep community members informed and involved.
660
INT-12 | Public Review Draft Introduction | March 2025
eBlasts
Throughout the update process, the City sent timely eBlasts to the General Plan contact list, which included elected and appointed officials, City Staff, stakeholders, and engaged community members. People could join the contact list through a link on the project website, by signing-in at a General Plan community workshop or public meeting, or by directly contacting the City of American Canyon.

Circulation Element Advisory Committee Meetings
The Circulation Element Advisory Committee recommended a road alignment for the “West Side Connector,” along with programs and policies for multimodal transportation solutions throughout the City.

Education and Lifelong Learning Element Advisory Committee Meetings
The Education and Lifelong Learning Element Advisory Committee provided recommendations for educational needs for all residents, including children younger than public school age and adults of post-secondary education age and seniors.

Parks and Recreation Element Working Group meetings
The Parks and Recreation Element Working Group will provide recommendations to meet the parks and recreation needs of all residents and it is anticipated that this effort will effectively result in a new Parks and Community Services Master Plan.

Planning Commission and City Council Meetings, Study Sessions, and Public Hearings
The City held various Planning Commission and City Council meetings, study sessions, and public hearings throughout the update process to inform decision-makers and the public, discuss key milestones, and provide direction for the next steps.

Goals and Policies
Each element contains the goals and policies that the City will use to guide future land use, development, resource management, and environmental protection decisions. Figure I-3 explains the standard format for goals and policies, using a sample goal and policy.

INT-Figure 3: How to Read Goals and Policies
665

1. INTRODUCTION
Public Review Draft Introduction | March 2025 | INT-17
Goal
A goal is a statement that describes in general terms a desired future condition or “end” state. Goals describe ideal future conditions for a topic and tend to be very general and broad.

Policy
A policy is a clear and unambiguous statement that guides a specific course of action for decision-makers to achieve a desired goal.
“Shall” vs. “Should”
Policies and implementation measures throughout the General Plan use terms such as “shall” and “should” to define the intentions of the City relative to these components. These modifiers are used as follows in the General Plan:
“Must” or “shall” or “required” are used to signify a mandatory requirement that the City will follow. For example, Policy U-4.4 says: “Continue to participate in the National Flood Insurance Program. To this end, the City shall ensure that local regulations are in full compliance with standards adopted by the Federal Emergency Management Agency (FEMA).”
Words such as “should” or “may” are used to signify a less rigid directive, that will be honored in the absence of compelling or contravening considerations.

For example, Policy U-2.5 says: “Subject to State regulations and organizational capacity, consider new ways that recycled water can replace potable water. ” This provides flexibility in addressing the policy in the context of the project or proposal.

Implementation Programs
Many policies will be implemented as part of routine City operations, and some policies require specific actions. The final section of each Element includes a table of implementation programs in a format illustrated on Figure I-4. Each implementation program will be evaluated in light of City resources, such as financial, staffing, and technology over the 20-year planning period. 666
INT-18 | Public Review Draft Introduction | March 2025
INT-Figure 4: How to Read Implementation Programs
Maintaining the General Plan
Over time, the City’s population will likely increase, its goals will evolve, and the physical environment will change. In order for the General Plan to remain relevant to current needs, it must be monitored and periodically revised to respond to changing conditions and needs over time.

The General Plan should be reviewed annually, with a more comprehensive and thorough review and revision done every ten years to reflect changes in local conditions, new local priorities, or State law. Though not required, many cities and counties will undertake a technical review of their general plan five years after adoption. State law permits the General Plan to be amended up to four times in any calendar year unless special conditions apply as defined by 667

1. INTRODUCTION
Public Review Draft Introduction | March 2025 | INT-19
Government Code Sections 65358(c) and (d). Each amendment may contain more than one change to the General Plan.

General Plan Amendments can be initiated by the City or at the request of a property owner. Each General Plan Amendment is subject to review under the California Environmental Quality Act (CEQA) and goes through a public review process, including hearings with the Planning Commission and City Council.

While specific findings may be applied on a project-by-project basis, at a minimum the following standard findings shall be made for each proposed General Plan amendment:

1. The amendment is deemed to be in the public interest;

2. The amendment is consistent and/or compatible with the rest of the General Plan and any implementation programs that may be affected; Justification: As a matter of State law, the City Council should be free to amend the general plan even if it would affect any implementation programs. Implementation programs should be made consistent with any general plan amendments, not the other way around, to assure vertical consistency.

3. The potential impacts of the amendment have been assessed and have been determined not to be detrimental to the public health, safety, or welfare; and

4. The amendment has been processed in accordance with the applicable provisions of the California Government Code, the California Environmental Quality Act (CEQA), and the City’s Municipal Code.

City-initiated amendments, as well as amendments requested by other public agencies, are subject to the same basic process described above to ensure consistency and compatibility with the General Plan. This includes appropriate environmental review, public notice, and public hearings, leading to an official action by the City Council.

2. LAND USE
Public Review Draft Land Use Element | March 2025 | LU-3 Land Use Diagram and
Designations
The Land Use Element designates land uses that achieve the development vision for the city through the 2040 planning horizon year.

The core of the Land Use Element is the land use diagram and land use designations that distinguish the various land uses in the City. Corresponding levels of intensity, density, and allowable uses are defined in this section, as required by Government Code Section 65302(a).

The General Plan development projections were determined by analyzing vacant and underutilized parcels within the city and the realistic level of development potential based on what is allowed under the applicable land use designation factoring for known physical constraints and/or regulatory requirements.

Planning Boundaries
The following planning boundaries are recognized as part of the American Canyon General Plan:
• City Limit. The political boundary within the incorporated city limits.

American Canyon has land use authority over all land within its city limits.
• Sphere of Influence. The Local Agency Formation Commission (LAFCo) establishes the Sphere of Influence (SOI), which defines the probable future incorporated City boundary. An SOI typically includes areas where the City already has or plans to have responsibility to provide municipal facilities and services.
• Urban Limit Line. The City’s Urban Limit Line was adopted by the City Council in response to a 2008 voter initiative (Resolution 2008-106).

This Urban Limit Line was coordinated with Napa County to be consistent with the County’s General Plan and City-centered urban growth policies. The 2040 General Plan extends the existing ULL indefinitely from a 2030 expiration date and includes consideration of an addition of the Hess/Laird Property northeast of the city’s current Important Note

LU-4 | Public Review Draft Land Use Element | March 2025 ULL which addition will occur concurrently with the indefinite extension of the ULL. Justification: The CEQA NOP includes the Hess/Laird property as Future Study area, not an outright addition to the ULL.
• General Plan Planning Area. A General Plan, pursuant to State law, must address all areas within the jurisdiction’s Planning Area that bears a physical relationship to the long-term planning of the city.

Consistent with this principle, the General Plan Planning Area includes the City of American Canyon Water and Sewer Service area, City, SOI, and ULL. Unincorporated Napa County has land use authority within the Extraterritorial Water and Sewer Service area, however, as the Water and Sewer Service provider, the City’s Extraterritorial Water and Sewer Service area bears relation to the City’s planning consistent with Gov. Code §65300.

Figure LU-1, the General Plan Planning Area Diagram, shows the planning boundaries that make up the General Plan Planning Area. 673

674
LU-6 | Public Review Draft Land Use Element | March 2025 Land Use Diagram
Figure LU-1, the General Plan Land Use Diagram, shows the distribution of the land use designations within the City’s Planning Area. There are 14 residential, commercial, mixed-use, and public/quasi-public uses land use designations within the City’s Planning Area.

The Land Use Diagram is intended to be more general than the Zoning Map.

While the Land Use Diagram guides zoning, it is not the same as the City’s Zoning Map. Each land use designation has one or more corresponding compatible zoning districts. Whereas the land use designations are intentionally broad, the zoning designations are more detailed and provide specific development standards, including permitted and conditional uses, building heights, setbacks, lot coverage, and parking requirements.

Land Use Designations
Table LU-1 describes the land use designations along with their corresponding density/intensity standards:
• Designation. This provides the name of each land use designation and the acronym used when referring to the designation.
• Color. Each land use designation has an assigned color used in the Land Use Diagram (Figure LU-2).
• Description. This describes the purpose and application of each land use designation. The City’s Zoning regulations provide further detail about uses allowed and permitted in zoning districts that implement the land use designations.
• Density/Intensity Standards. This describes development density or intensity. Designations allowing residential uses include a minimum and maximum density, expressed as dwelling units per acre (du/ac).

Non-residential uses include maximum building intensity standards, expressed as Floor Area Ratio (FAR), which is defined below. Most non-residential land use designations also allow residential uses and include density standards as well.
675

2. LAND USE
Public Review Draft Land Use Element | March 2025 | LU-7 Residential Density
Development is defined by allowed density (minimum
and maximum) measured in dwelling units per acre
(du/ac). Residential density is calculated by dividing the number of dwelling units on a site (excluding accessory dwelling units) by the gross acreage of the site. The
image to the right shows prototypical examples of
different residential densities for one-acre properties.

State planning law requires general plans to include
standards for measuring population density. Population
density is determined by multiplying the maximum
number of dwelling units allowed in a given land use
designation by the average number of persons per household (as determined by the California Department of Finance). Standards of density for residential uses are stated as the allowable range (i.e., minimum and maximum) of dwelling units per gross acre (du/ac).

Floor Area Ratio (FAR)
Standards of building intensity for nonresidential uses such as office, commercial, industrial, and institutional development are defined in terms of floor area ratio (FAR). FAR is an indicator of how much building space is permitted on a given site. In the case of mixed-use developments that include residential uses, density standards are applied to the residential component while FAR standards are applied to the nonresidential component. A site includes all contiguous parcels that will share parking or access. 676
LU-8 | Public Review Draft Land Use Element | March 2025 While FAR provides overall development intensity, it does not specify the form or character of the building. Different configurations of the same FAR can result in buildings of different character. To encourage building configurations of allowed FARs consistent with community vision, zoning regulations identify height limits, building setbacks, lot coverage, or open space requirements to guide the form of buildings with a given FAR.

Future Study Area
As part of the General Plan Update the City identified a future study area (Figure LU-3) that has the potential for additional growth. This future study area encompasses the Hess/Laird property which is currently located within the jurisdiction of Napa County and was recently general planned and rezoned for industrial uses. As a Future Study Area, the general plan does not identify specific uses for the Hess/Laird property under CEQA at this time. Thus, it would be speculative to evaluate any such uses at this time.

When the City evaluates this Study Area for inclusion in the City’s Urban Limit Line, the process will evaluate future uses as part of a subsequent CEQA 681

At this time the General Plan does not anticipate growth for this future study area within the horizon year of this Plan but is highlighting it for future potential if and when the City decides to expand. Justification: The new language further explains the reason for not identifying a land use in the Hess/Laird Future Study Area.

2. LAND USE
Public Review Draft Land Use Element | March 2025 | LU-15 Goals and Policies
Growth Management and Phasing
The City of American Canyon was incorporated on January 1, 1992. Since then, the City has grown to a population of more than 21,000. American Canyon is home to three elementary schools, one middle school and one high school and dozens of businesses. Positioned along Highway 29 in Southern Napa County, the City is the SF Bay Area’s entry point to the Napa and Sonoma Valley wineries.

The City’s focus is on strengthening the local economy and increasing job opportunities in American Canyon to enable more residents to work closer to home and sustain and enhance the long-term economic viability of the City.

The City is also focused on capitalizing on tourism and preserving the unique environmental resources and character of the area. Revitalization of vacant and underutilized properties and quality new development are key to the city’s future. Policies in this section give American Canyon the tools to grow and change through 2040. They provide structure and guidance, while allowing flexibility to adapt to economic, environmental, and social change.

Goal LU-1:

Establish American Canyon as a "complete city” with a diversity of distinct land uses that serve the needs of residents, businesses, and visitors. (Source:

Existing Goals 1.1A and 1.1C, modified)

2. LAND USE
Public Review Draft Land Use Element | March 2025 | LU-25 Airport Compatibility
Napa County Airport abuts the City Urban Limit Line. This represents both an opportunity and a constraint. The airport provides an economic stimulus for the development of industries and commercial businesses in American Canyon. Airport operations result in noise and the potential risk of accidents that impact nearby land uses. The goals and policies in this section are intended to mitigate any potential hazards and assure compatibility of new development with the airport.

The Napa County Airport Land Use Compatibility Plan (NALUCP) was adopted by the Napa County Airport Land Use Commission (ALUC) on December 4, 2024. The NALUCP is incorporated into the General Plan as a standalone document identified as Appendix 3 Napa County Airport Land Use Compatibility Plan.

Public Review Draft Mobility Element | March 2025 | M-3 Mobility Vision
The City of American Canyon is a community that embraces mobility through all transportation modes. The core value of the Mobility Element is to provide safe and easy travel for pedestrians, bicyclists, transit riders and motor vehicles correlated with the Land Use Element.

This community mobility value is based on enhancing the City’s " sense of place" with a strong emphasis on all forms of mobility safety and environmental protection. An efficient multi-modal plan will improve our sense of place, provide greater mobility choice for all residents, and help the environment. 710
M-4 | Public Review Draft Mobility Element | March 2025 Introduction
The Mobility Element provides a vision and guiding principles for the transportation system, and detailed goals and policies which implement a compete streets approach to mobility in the future.

Local transportation planning is a coordinated effort involving local and regional agencies. The goals and policies set forth in this document are intended to promote local planning, but also foster cooperation between jurisdictional partners such as the Napa Valley Transportation Authority (NVTA), the Metropolitan Transportation Commission (MTC) and the California Department of Transportation (Caltrans).

The transportation planning and policy in the Mobility Element includes a critical component of the City's responsibility towards supporting regional efforts to meet greenhouse gas reduction targets, through coordinating planning for land use, transportation, and housing. The Regional Transportation Plan and Sustainable Community Strategy (RTP/SCS) for the San Francisco Bay Area, Plan Bay Area 2050, was jointly produced and adopted by the Metropolitan Transportation Commission (MTC) and Association of Bay Area Governments (ABAG) on October 21, 2021. Plan Bay Area 2050 is the strategic update to Plan 711

4. MOBILITY
Public Review Draft Mobility Element | March 2025 | M-5 Bay Area 2040, and it connects the elements of housing, the economy, transportation, and the environment through 35 strategies that will make the Bay Area more equitable for all residents and more resilient in the face of unexpected challenges. It is a roadmap to help Bay Area cities and counties preserve the character of our diverse communities while adapting to the challenges of future population growth.

A portion of the Planning Area - the Broadway District (SR 29) corridor - has been designated by MTC and ABAG as a Priority Development Area (PDA), meaning that it is recognized as an area with substantial opportunity for infill development near transit. PDAs play a critical role in accommodating future growth in the regional agencies' SCS plans.

California Planning Requirements
Required General Plan Element. California law mandates a “Mobility Element” or “Circulation Element” that contains the “general location and extent of existing and proposed major thoroughfares, transportation routes, and other local public utilities and facilities, all correlated with the land use element” of the General Plan per Government Code Section 65302 (b).

Complete Streets Act. The term “complete streets” refers to a balanced, multimodal transportation network that meets the needs of all users of streets -- including bicyclists, children, persons with disabilities, motorists, movers of commercial goods, pedestrians, public transportation, and seniors. A complete street is one that provides safe and convenient travel in a manner that is suitable to the local context. In 2012, the City adopted a Complete Streets Policy (Resolution 2012-72).

The Mobility Element is consistent with the California Complete Streets Act (AB 1358), which requires cities and counties incorporate “Complete Street” policies when updating their General Plan Mobility Element. Complete streets make travel safe for all users, including bicyclists, pedestrians, motorists, transit vehicles, and people of all ages and abilities. While every street does not need to provide dedicated space to all users, the street network must accommodate the needs of all users.

Economically, complete streets help lower transportation costs by enabling people to use transit, walking, or bicycling rather than driving to reach their destinations. Caltrans is actively engaged in implementing its complete streets policy in all planning, programming, design, construction, operations, and maintenance activities for the State Highway System.
712
M-6 | Public Review Draft Mobility Element | March 2025 Provision of safe mobility for all users contributes to the Caltrans’s vision:
"improving mobility across California.” The successful long-term implementation of this vision will provide more options for people to travel from one place to another, less traffic congestion, fewer greenhouse gas emissions, more walkable communities (with healthier, more active people), and fewer barriers for older adults, children, and people with disabilities.

Local Roadway Safety Plan. American Canyon is currently preparing a Local Roadway Safety Plan (LRSP). Required for an agency to apply for federal Highway Safety Improvement Program (HSIP) funding, the LRSP will proactively correct high collision or problem locations and prevent local road fatalities and injuries. The final plan will recommend proven countermeasures, provide a structure and realistic set of responses that implement changes over time, will integrate the “4 E’s” approach (Education, Enforcement, Emergency Service, and Engineering) in its proposed solution strategies, and identify road safety partners that could sustain a long-term effort.

Traffic Calming Program. The American Canyon “We ❤ Safe Streets” Traffic Calming Program provides a framework for the community to submit concerns of problem areas to our Traffic Calming Team for evaluation. The Program includes criteria to assess the magnitude of the need to modify a street or roadway, and probable effectiveness of a potential traffic calming measure installation.

Capital Improvement Programs. California Government Code Section 65401 specifies public works projects must conform to the General Plan. In practice, this requires the Five-Year Capital Improvement Program (CIP) adoption include findings that the proposed City of American Canyon Five-Year CIP conforms with the General Plan, which includes the Mobility Element.

Vehicle Miles Traveled. The Mobility Element is consistent with Senate Bill (SB) 743 directing changes to the California Environmental Quality Act (CEQA) guidelines that established Vehicle Miles Traveled (VMT) as the transportation metric analyzed under CEQA, effective July 1, 2020. Using VMT as the transpor713

4. MOBILITY
Public Review Draft Mobility Element | March 2025 | M-7 tation CEQA metric is intended to emphasize statewide goals related to infill development, transit investments, promotion of public health through active transportation, and reduction of GHG emissions over local needs to manage traffic congestion on local road networks.

Transportation impact analysis under CEQA is no longer based on level of service (LOS), which focused on motor vehicle delay. The new CEQA standards require transportation impacts associated with development be assessed primarily on the effects of VMT.

While LOS is no longer related to CEQA, LOS-based performance goals remain relevant for non-CEQA planning purposes and as a tool for the City to ensure its roadway system meets the expectations of the community on criticallyimportant roadways. 714
M-8 | Public Review Draft Mobility Element | March 2025 Transportation Setting
The city of American Canyon is located in southern Napa County, about 35 miles northeast of San Francisco. Adjacent and south of the city limits is the city of Vallejo in Solano County. North of the city limits, the cities of Napa, , St. Helena, Calistoga, and the Town of Yountville are located along State Route 29 (SR 29) which is a main route to wine country destinations. As with American Canyon, these jurisdictions are bisected by SR 29.

American Canyon had an estimated population of 21,800 in 2020, an increase from 19,454 in 2010 and 9,774 in 2000. It is the second most populated city in the County after the city of Napa. With its recreational options, local wineries, and proximity to Napa Valley, Sonoma County, the East Bay, San Francisco, and easy access to Sacramento, American Canyon sees many different types of roadway users each day.

State Route 29 runs through the city mostly at-grade and serves as a main thoroughfare for local and pass-through traffic. In addition, American Canyon roadways serve a variety of users including pedestrians, bicyclists, transit riders, passenger cars, and heavy trucks for freight, with a mix of local, recreational, and regional trips.

MOB-Figure 1 shows the existing mobility system map. Traffic to and from the I80 corridor is served by American Canyon Road and Jameson Canyon Road (SR 12). Access to and from Vallejo and the East Bay, including the Counties of Contra Costa and Alameda, is provided via Flosden Road and SR 29. To and from the north, access is provided via SR 29 and SR 12, which also collects traffic from the rest of Napa County. Marin and Sonoma counties to the west and northwest may also access the city using SR 29 via SR 37.

Rail transportation in the City is currently limited to freight service only. No commuter rail service exists in the city or county. The main rail line in the city is owned by Union Pacific Railroad Company and enters the city parallel to and on the east side of SR 29 at the Solano County line.

During the five-year period between 2017 and 2021, there were two fatal and five severe injury collisions recorded for the roadways under the City of American Canyon’s jurisdiction. There were two fatal and 10 severe injury collisions on SR 29. MOB Figure -3 shows the locations of fatal and severe injuries.

Active Transportation
There are currently over 13 miles of bicycle network within American Canyon, including over 8 miles of Class I multiuse paths, 2.8 miles of Class II bike lanes, and over 2 miles of Class III designated bicycle routes on public roadways. While most of the city has sidewalks, given the rural character of many older neighborhoods and the lack of a centralized downtown area, several areas of the city have limited or lacking pedestrian infrastructure. There is minimal sidewalk coverage along SR 29, which serves as the main commercial corridor through the center of American Canyon. MOB-Figure 4 shows the locations of collisions involving bicyclists from 2017-21, which are concentrated on American Canyon Boulevard. MOB-Figure 5 shows the locations of collisions involving pedestrians from 2017-21 which primarily occurred on SR 29 and American Canyon Boulevard.

Public Transit Service
Public transportation within the city is provided by American Canyon Transit, which is a part of the Napa Valley Transportation Authority (NVTA) Vine Transit system. American Canyon Transit is a fixed route and on-demand, door-to-door, transit service within specific areas of the city. Vine’s Route 29 (Napa-BART) Express connects the BART Station in El Cerrito to the Redwood Park-n-Ride in 718

M-16 | Public Review Draft Mobility Element | March 2025 Airport
The Napa County Airport is just northwest of the city limits in unincorporated territory. It is a General Aviation airport with charter flights available, but no scheduled commercial flights. The airport can accommodate most private aircraft including jets, up to 120,000 pounds. The airport was built by the United States Army Air Force in 1942 and was deeded to Napa County after World War II for civilian use. The nearest general passenger airports are in Oakland, San Francisco, and Sacramento.

Land use planning in the airport area is subject to the Napa Airport Land Use Compatibility Plan which was adopted by the Napa County Airport Land Use Commission in December 2024. In 2010, the Napa County Airport Land Use Commission deemed the American Canyon General Plan in conformance with the Napa Airport Land Use Compatibility Plan (#P109-0002-ALUC).

Justification: Updates the status of the Napa County Airport Land Use Plan and the evolving capacity to accommodate aircraft.

Street System Plan
The planned street network will provide an efficient transportation system that includes a citywide network of complete streets. A commitment to providing complete streets is a key to effective transportation planning and will maximize the effectiveness of the existing street network.

Street Classifications
American Canyon consists of a network of complete streets. These streets play an integral role in connecting the city to other destinations in Napa County, the adjacent city of Vallejo, Solano County, and the San Francisco Bay Area. MOBFigure 6 shows the planned buildout street network based on the following classifications:
• Arterial Streets. Arterial facilities serve all travel modes and connect areas of major activity within the urban area. Arterials also distribute motor vehicle traffic from freeways/highways to collector streets.

Within the city, arterial streets provide four motor vehicle lanes with bicycle lanes and sidewalks, and maximum operating speeds currently ranging from 30 to 45 mph, including American Canyon Road, Flosden 723

4. MOBILITY
Public Review Draft Mobility Element | March 2025 | M-17 Road, and Newell Drive. State Route (SR) 29 is a Regional Arterial that bisects the city and provides interregional access to the city of Vallejo in the south, and the rest of Napa County to the north. SR 29 serves a dual purpose of providing local cross-town circulation for all travel modes, as well as serving significant regional travel primarily by motor vehicle, including public transportation. The regional travel contains two components - regional "through" traffic that does not originate or terminate in the city, and regional-local "commute" traffic that originates in the city but terminates outside, or vice-versa. • Collectors. Collector streets serve all travel modes and function as connector routes between local and arterial streets and provide access to residential, commercial, and industrial property. Collector streets within the city typically provide two motor vehicle lanes (one per direction) with current maximum operating speeds of 30 mph and include Broadway Street, Eucalyptus Drive, Green Island Road, Rio Del Mar, and Donaldson Way, Commerce Boulevard, among others. • Local Streets. Local streets provide direct access for all travel modes to abutting properties and allow for localized movement of traffic. Local streets are characterized by low daily traffic volumes and current operating speeds of 25 to 30 mph.

SR 29 Corridor Planning
724
M-18 | Public Review Draft Mobility Element | March 2025 Broadway (SR 29) is a four-lane highway through American Canyon. Between Napa Junction Road and American Canyon Road, Broadway defines the City’s character to our residents, business community, and thousands of drivers that pass through our City each day. Local planning efforts have resulted in the development of preliminary concepts for SR 29 that have been presented to the public through workshops for input and comment.

Planning for the State Route 29 (SR 29) corridor is an issue of significant importance not only for the city, but for the entire region. Both Solano County to the south and Napa County to the north rely on SR 29 for mobility-for work, school, shopping, and recreation.

As a State facility, Caltrans plays an important part in approving and funding improvements to SR 29. State funding for improvements is provided through Caltrans, and planning efforts require approval from Caltrans prior to implementation.

Currently, the Napa Valley Transportation Authority (NVTA) in partnership with the City, is preparing the American Canyon Multimodal Improvement Project.

This effort is considering two Options for improving Broadway between Napa Junction Road and American Canyon Road. Both Options contemplate landscape and pedestrian improvements, and multimodal features. Option 2 would maintain the existing 4-lane roadway configuration with roundabouts at major intersections.

Public Review Draft Mobility Element | March 2025 | M-19 MOB-Figure 7:American Canyon Multimodal Improvement Project Option 2 Newell Drive Extension
The Mobility Element street network includes extension of Newell Drive north from its current terminus concurrent with future development. MOB-Figure 8 shows the planned conceptual future alignment of Newell Drive. The precise alignment will be determined through future planning processes. As envisioned, Newell Drive would eventually connect American Canyon Boulevard in the south with SR 29 at Green Island Road and would also connect with North Kelly Road to the north of American Canyon. The future extension would be a 2- lane collector with one motor vehicle lane in each direction, bicycle lanes and sidewalks.

Justification: The modified language clarifies that the future Newell Drive alignment will be known when precise engineering occurs.

Vision Zero
The Mobility Element includes Vision Zero goals and policies. Vision Zero aims to eliminate all traffic fatalities and severe injuries, while increasing safe, healthy, and equitable mobility for all. Traffic deaths and injuries can be reduced over time by prioritizing traffic safety as a public health issue. The City of American Canyon Local Roadway Safety Plan (LRSP) identifies safety countermeasures to improve safety.

Public Review Draft Mobility Element | March 2025 | M-21 Bikeway Network Plan
American Canyon is ideally situated for bicycle and pedestrian mobility, with a generally flat topography, scenic landscapes in the Newell Open Space and Napa River Wetlands a short distance to the east, west, and north. Combined with the Napa Valley Vine Trail, the goal is to interconnect American Canyon as well as the surrounding communities in the County with a seamless bicycle network for recreational and commuter use. The plan includes proposed bicycle and pedestrian trails, as well as on-street bicycle facilities to complete the partial network already in place in the city and county.

Types of Bikeways
Four classes of bikeways are defined by Caltrans:
• Class I Multi Use Path. Typically known as bike paths, Class I facilities are multi-use facilities that provide a completely separated right-of-way for the exclusive use of bicycles and pedestrians with cross flows of motorized traffic minimized.
• Class II Bike Lane. Known as bike lanes, Class II facilities provide a striped and signed lane for one-way bicycle travel on each side of a street or highway. The minimum width for bike lanes ranges between four and five feet depending upon the edge of roadway conditions (curbs). Bike lanes are demarcated by a six-inch white stripe, signage and pavement legends.
728
M-22 | Public Review Draft Mobility Element | March 2025 • Class Ill Bike Route. Known as bike routes, Class Ill facilities provide signs for shared use with motor vehicles within the same travel lane on a street or highway. Bike routes may be enhanced with warning or guide signs and shared lane marking pavement stencils. While Class Ill routes do not provide measures of separation, they have an important function in providing continuity to the bikeway network.
• Class IV Separated Bikeway. A Class IV Bikeway is for the exclusive use of bicycles and includes a separation between the bikeway and adjacent vehicle traffic. The physical separation may include flexible posts, grade separation, inflexible physical barriers or on-street parking. Separated bikeways generally operate in the same direction as vehicle traffic on the same side of the roadway. However, two-way separation bikeways can also be used, usually in lower speed environments (35 miles per hour or less).

Currently, bikeway facilities separated from vehicular traffic in American Canyon include a network of recreational pathways located throughout the community in City parks and on the American Canyon Creek corridor, a north-south ClassI Multi-use Path along Flosden Road and Newell Drive, and a Bay Trail pathway on Wetlands Edge Road. Class II bike lanes are provided on ElliotDrive, Broadway Street, Benton Way, Donaldson Way,American Canyon Road, and Kimberly Drive. Connecting gaps in the planned trail network is a high priority for the City.

Bicycle Plan
The City adopted a Bicycle Plan in 2020 (Resolution 2020-11) which is incorporated into the General Plan as Appendix 4-1. The Bicycle Plan was prepared by the NVTA in accordance with the California Bicycle Transportation Act as part of the Napa Countywide Bicycle Plan.

American Canyon has a variety of public transportation options including fixed route systems and demand-responsive systems as well as local systems and regional systems.

American Canyon Transit
American Canyon Transit (ACT) is a part of the Napa County Transit (VINE) family of services operated by the NVTA. ACT is a bus service that provides a 90-minute round trip route through the city on weekdays between 7:30 AM and 6:00 PM.

ACT provides one main route served by two buses, ACT-1 and ACT-2, as well as a Peak Service route during the morning. The ACT buses will deviate from routes and provide on-demand service as time permits for disabled and senior citizens.

Route ACT-1 Southbound starts at 6 am weekdays from the ACT bus stop on Main Street next to Wal-Mart. ACT-1 travels southbound via Rio Del Mar to Donaldson Way and continues (blue route on Figure 5) Route ACT-2 Northbound starts at 10 am weekdays from the ACT bus stop on James Street at Crawford Way. ACT-2 travels easterly via Donaldson Way to southbound Shenandoah and continues (blue route on Figure 6).

The AM Peak Service makes two loops in the AM. The first loop is from the WalMart bus stop at 7:25 am, and the second loop is from the Rio Del Mar/Eucalyptus intersection (7-Eleven) bus stop (green route on Figure 6). This route is designated as the "American Canyon High School" route, as depicted on the bus front signs.

VINE
VINE provides services outside the ACT routes between several cities in Napa County. Within the City, Route 10, and VINE 29 offer bus stops within the city limits. Route 10 (purple route on Figure 6) runs from Napa Valley College in the city of Napa to the city of Vallejo and stops at SR 29/Rio Del Mar and at the American Canyon Senior Center on Elliot Drive between Knightsbridge Way and Kimberly Drive.

VINE 29 (yellow route on Figure 6) is a commuter express route from Calistoga to El Cerrito Del Norte BART and the Ferry Terminal in Vallejo.

Goods Movement
Truck Routes
Truck routes are intended to carry heavyweight commercial, industrial, and agricultural vehicles through and around the community with minimum disruption to local auto traffic and minimum annoyance to residential areas. Due to the high level of existing and expected future light industrial activity in the northwest quadrant of the City, truck routes should be clearly designated so that intrusion of heavy vehicle traffic into residential areas can be avoided.

Green Island Road, and SR 29 are the City's designated truck routes. Currently, SR 29 carries significant truck traffic and is designated as a Surface Transportation Assistance Act (STAA) terminal access route. The 1982 Surface Transportation Assistance Act set standards for large trucks, known as STAA trucks, and set minimum truck sizes that states allow on the National Network including the Interstate System and other defined routes, such as SR 29.

Rail Transport
Rail transportation in the American Canyon is limited to freight service only. The main rail line is owned by Union Pacific Railroad Company and enters the city from the City of Vallejo parallel to and on the east side of SR 29.

The rail line continues on this trajectory diverting from the SR 29 alignment north of American Canyon Road. North of Napa Junction Road, the railroad line splits into three segments:
• One segment heads northeast parallel to Jameson Canyon Road towards the city of Fairfield.
• Another segment heads northwest under SR 29 and across Green Island Road toward the city of Sonoma.
• The third leg heads north past Napa County Airport, terminating just north of Kennedy Park in the city of Napa. This leg connectsto the Napa Valley Wine Train.

Public Review Draft Mobility Element | March 2025 | M-41 The Napa Valley Railroad operates a tourist-oriented passenger train service between the City of Napa and St. Helena. The Wine Train makes multiple round trips per day between the two cities.

In 2003, the NVTA studied potential passenger rail service from the Vallejo Ferry Terminal north to St. Helena or Calistoga. The Napa/Solano Passenger/Freight Rail Study concluded that passenger rail service could be feasible. However, the service would require a significant subsidy with no current funding source.

In 2019, Sonoma-Marin Area Rail Transit (SMART) completed a Passenger Rail Service Feasibility Study for a 41-mile Novato to Suisun City corridor. This study determined that this corridor is feasible for passenger rail including a potential rail station in American Canyon.

Supply
A reliable source of water sustains our population, economy, and ensures long term growth. This section focuses on American Canyon’s existing potable water system, including water sources, treatment capabilities, and conservation practices.

Water/Wastewater Service Area
At the time of City incorporation in 1992, the City acquired the water and wastewater services provided by the American Canyon County Water District.

As a subsidiary agency, the water system is owned and operated by the City and governed by a five-member City Council.
• The City’s water service area is approximately 30 square miles (see Figure 3-1) and comprises of the following areas:
• The City itself, which is approximately 6 square miles and includes residential, commercial, industrial and agricultural users; • The commercial/industrial areas in and around the Napa County Airport located north of the City (unincorporated Napa County), which covers approximately 5 square miles; and
• The largely open space/agricultural areas to the west, east and north of the City limits (unincorporated Napa County), which include agricultural users and a small number of single-family residential customers who represent “legacy” accounts that were originally connected and served by the American Canyon County Water District.

A graphic depicting the historical water service area is shown on the figure below.

5. UTILITIES
Public Review Draft Utilities Element | March 2025 | U-5 Water Supply
The City’s water supply primarily comes from the State Water Project. The State Water Project is designed, constructed, operated, and maintained by the California department of Water Resources and supplies water for 25 million Californians.

Lake Oroville is the largest State Water Project reservoir, one of 21 reservoirs that collects water for distribution. The water travels to American Canyon through several miles of the North Bay Aqueduct (NBA) and is delivered to tanks near the Jameson Canyon Road water treatment plant.

The City also receives supplemental water purchased from the Cities of Napa and Vallejo.

In 2017, the City became a partner in the Sites Reservoir Project, an environmentally beneficial, off-river reservoir that will capture excess water from major storms and save it for drier periods. This Project will help California’s farms, businesses, and cities continue to supply reliable water when other sources are low.

The City also produces and delivers recycled water to meet demand to private customers for agriculture, industrial, toilet flushing in apartment and commercial uses, and landscape irrigation.

According to the draft 2020 Urban Water Management Plan, the City anticipates it can meet water demands through the planning horizon year of 2045.

Potable Water Treatment
Raw water received through the North Bay Aqueduct system must be treated before potable use. American Canyon owns and operates a water treatment plant located at 250 Kirkland Ranch Road. The plant uses two processes to treat water, a conventional sedimentation and filtration process and a membrane filtration process. In total, the plant produces up to 5.5 million gallons of potable water each day within the water service area across 5,621 connections. The plant consistently meets the highest quality standards set forth by State and Federal regulations.
759
U-6 | Public Review Draft Utilities Element | March 2025 Water Conservation
Climate change is causing higher average temperatures, a decrease in precipitation, and longer and more frequent heat waves and droughts. These climatic conditions overall increase water demand. A key component to water reliability and adaptation to climate change is conservation. The City’s Zero Water Footprint directs that conservation offset new potable water demand.

These and other measures will be implemented to ensure adequate water supply and responsible water usage. The following are some of the water conservation programs the City is implementing to further conservation efforts.

Water Conservation Ordinances
American Canyon has adopted three ordinances to help further its conservation efforts. The first aims to reduce the amount of wasted water and the second and third require new developments to use water efficient landscaping techniques.

Water Metering
All potable and recycled water customers are metered and billed on a monthly basis. City staff reads meters on a monthly basis, utilizing meter reading to both document demand reductions from conservation and high-water use.

Conservation Pricing
American Canyon uses a tiered rate structure method to encourage water conservation. The tiered rate structure incentivizes conservation by reducing rates for low water users, while progressively increasing the cost per gallon for high water users. Since 2007, American Canyon has applied tiered water rates to all single-family residential users.

Public Education and Outreach
American Canyon is actively involved in water conservation through public outreach and education. City programs include distributing free water saving devices (i.e., shower heads, faucet aerators, shower timers), rebates for high efficiency toilets and clothes washing machines, public outreach through the City website, and the “Cash for Grass” program, which pays homeowners to replace turf with water efficient landscaping.

Wastewater
Wastewater collection and treatment is essential. American Canyon ensures wastewater is properly handled and reused for beneficial purposes. This section provides an overview of the City’s wastewater collection and treatment systems.

Infrastructure and Collection
Wastewater collection and treatment services are provided by the City’s Maintenance and Utilities Department. The Sewer Collection responds to reports of sewer spills and back-ups and monitors environmental compliance and water quality regulations. The City’s sewer infrastructure consists of 53 miles of gravity pipelines, five pump stations, five miles of sewer force mains, and the American Canyon Water Reclamation Facility (WRF). This infrastructure collects and treats wastewater from both domestic and industrial customers.

The City has plans to further develop this infrastructure to address population growth.

Treatment
The American Canyon Water Reclamation Facility (WRF) treats domestic and industrial wastewater flows from the city. The treatment plant discharges treated wastewater it to the Napa River, via wetlands ponds, or to the City’s recycled water distribution system. The WRF was designed to treat an average flow of 2.5 million gallon per day (mgd) and has a wet weather capacity of 5.0 mgd. Average treatments flows in 2018 ranged from 1.54 to 1.62 mgd, which is well below the facility treatment capacity.

U-10 | Public Review Draft Utilities Element | March 2025 Recycled Water
American Canyon supplements its water supply with recycled water. (Source:

American Canyon StoryMaps) The City adopted a Recycled Water Implementation Plan in 2005, and has been working to expand its recycled water system in order to further reduce the City’s reliance on imported water supply.

The City’s Water Reclamation Facility (WRF) has the ability to produce recycled water that meets the Title 22 standards for disinfected tertiary water, which is suitable for a wide range of uses such as landscape irrigation in residential and commercial areas, school yards, parks and playgrounds. Title 22 (California Code of Regulations, Division 4, Chapter 3, §60301 et seq.) is the regulation that establishes the level of treatment, water quality standards and the types of uses for recycled water for the purpose of protecting public health.

Napa Sanitation District (NSD) also provides wastewater collection/treatment and recycled water services for northern portions of the City’s potable water service area. In addition, some users in the northern part of the City’s water service area receive recycled water from Napa Sanitation District (NSD).

NSD provides wastewater collection/treatment and recycled water services for the City of Napa and portions of unincorporated Napa County. In 2015, NSD provided approximately 210 acre-feet of recycled water for landscape and agricultural irrigation to customers located within the City of American Canyon’s potable water service area. NSD is also planning to expand its recycled water distribution, including to agricultural and commercial landscape irrigation users within the City’s potable water service area.

American Canyon operates a Residential Recycled Water Fill Station open to residents on a drop-in basis. The station is located at the City’s Corporation Yard, 205 Wetlands Edge Road. After a brief training on the applicable uses for the water, residents are provided up to 300 gallons free of charge. Recycled water taps are purple to easily distinguish them from standard potable water pipes.

This is an example of recycled water and

U-12 | Public Review Draft Utilities Element | March 2025 Flood Control and Storm Drainage
Stormwater is rainwater that does not quickly soak into the ground. Stormwater flows from rooftops, over impervious paved areas, and through lawns and fields.

As it flows, runoff collects into streams and rivers that transport soil, pesticides, fertilizer, oil and grease, leaves, litter, and other potential pollutants into local waterbodies. Due to its geographical location near sensitive watersheds, American Canyon plays a vital role in collecting stormwater runoff and preventing pollution that could be distributed in the surrounding sensitive environments.

Stormwater Infrastructure
The City of American Canyon Maintenance and Utilities Department oversees municipal storm drainage facilities within the city limits. The City’s storm drainage system collects stormwater runoff and discharges the water to the Napa River through a system of on-street storm drain inlets, ditches, detention basins, ponds, and bio-swales designed to increase groundwater infiltration and reduce sediment and pollutants.

Flooding and Flood Control
Seasonal flooding along the Napa River Watershed is a regular occurrence. In fact, there have been at least 22 serious floods on the river since 1865. During heavy rain, low-lying areas of American Canyon are subject to flooding along natural creeks and low-lying areas around the city.

According to the San Francisco Bay Conservation & Development Commission (BCDC), sea level rise from global warming has risen water levels in San Francisco Bay nearly eight inches over the past century, and the rate of sea level rise is accelerating. Since 2008, the BCDC has served as the State agency responsible for leading the Bay Area’s preparedness for, and resilience to, rising sea level, tides, and storm surge due to climate change.

Rising sea levels (SLR) will have widespread impacts on the Bay Area. Adapting to this hazard will cost billions of dollars over the next several decades. 766

U-16 | Public Review Draft Utilities Element | March 2025 Solid Waste Disposal and Recycling
Waste collection and management is important to protect the environment and health of the population. Proper collection and disposal of waste is a large task that involves logistical planning and scientific understanding to balance environmental impacts and cost effectiveness. This section describes American Canyons current sold waste collection and disposal efforts.

Collection
Solid Waste collection is provided by Recology American Canyon under the Napa-Vallejo Waste Management Authority (NVWMA). NVWMA contracts collection, hauling, and disposal of solid waste from the cities of Napa, Vallejo, and unincorporated areas in southern Napa County. Recology provides residents with regular garbage, recycling, and green waste/compost pickup. Waste collected from American Canyon is sorted at the Devlin Road Recycling and Transfer Facility, located at 889 Devlin Road in American Canyon before it is sent to nearby landfills.

Disposal
Solid waste from American Canyon is directed to the Solano County Potrero Hills Landfill, located at 3675 Potrero Hills Lane, Suisun City. The Potrero Hills Landfill is a Class III landfill that accepts a variety of waste types, including mixed municipal, construction/demolition waste, agricultural, sludge (biosolids), industrial, and other designated wastes.

As of 2014, Potrero Hills Landfill accepted 97 percent of the City’s total solid waste (i.e.: 12,896 tons). The Potrero Hills Landfill is expected to be in operation until 2048 with a remaining capacity of approximately 13 million cubic yards with up to 4,330 tons of waste per day.

On November 16, 2021, City Council adopted Ordinance No. 2021-08 modifying Title 8 (Health and Safety) of the American Canyon Municipal Code to add “Chapter 8.20 Mandatory Municipal Solid Waste, Recycling and Compost Material Disposal Reduction.” A requirement of State Senate Bill 1383 (SB 1383), the Ordinance will:
• Divert 50 percent of organic waste from landfills below 2014 levels by 2020 and 75 percent by 2025;
The Potrero Hills Landfill located in
Solano County.

Public Review Draft Utilities Element | March 2025 | U-19 Energy Utilities
Energy in many forms is an essential public service. As energy demand increases it may strain existing energy systems and resources. A shift toward alternative energy resources can supplement future demands sustainably.

Shift to Renewable Energy
Since 2016, the City has been enrolled in the Light Green program, Marin Clean Energy (MCE)’s default energy plan that offers 60% renewable energy. In 2021, American Canyon City Council voted to supply the City's facilities with MCE Deep Green 100% renewable energy. The change to Deep Green will remove approximately 247,000 pounds of carbon dioxide from American Canyon’s carbon footprint per year. (Source: Media Release - American Canyon Opts Into 100% Renewable Energy for Its City Facilities, 2021)
The City’s switch to Deep Green adds to a growing list of American Canyon’s clean energy initiatives, including the Citywide Energy Efficiency and Resiliency Project (CEERP). The City joined MCE in 2016 and has since been enrolled in the electricity provider’s 60% renewable energy option. Before switching to MCE, the City was enrolled in Pacific Gas and Electric's (PG&E) 29% renewable option.

MCE is an alternative to PG&E for energy generation; all residents and local businesses were automatically enrolled in Light Green also have the option to opt up to Deep Green. Customers pay higher rates for Deep Green but do not have to pay any upfront fees to upgrade. (Source: Media Release - American Canyon Opts Into 100% Renewable Energy for Its City Facilities, 2021) In addition to the City’s association with a greener electric source from MCE, residents have installed solar energy at their homes with rooftop photovoltaic panels (PVEs). The Residential PVE permit activity trends show increasing onsite, carbon free energy generation. Changes in building codes that call for greater energy efficiency in all new construction will increase this trend for the foreseeable future.

7. ENVIRONMENT, PARKS & RECREATION
Public Review Draft Environment, Parks & Recreation Element | March 2025 | ENV-3 Introduction
American Canyon’s environmental resources are critical features that define our character and quality of life. In our community, environmental resources include:
• Biological Resources
• Water Resources
• Soil Resources
• Cultural and Historic Resources
• Regional and Local Open Space
• Parks and Recreation
• Scenic Resources
• Air Quality and Climate Change
Why Is Protecting the Environment and enhancing Recreation and Open Space Important?
Our natural environment, combined with recreation and open space are central features of our community’s quality of life. Preserving the environment retains important ecosystems that life itself depends. For American Canyon residents, our environment defines American Canyon as our home – a place with familiar physical features that endure for generations.

The City’s open space system provides places for recreation, activity, and engagement, for peace and enjoyment, and for freedom and relief from the built world. Physical recreation reduces obesity and risk of cardiovascular disease, diabetes, and other health ailments. Public open spaces, whether playgrounds, picnic fields or even just engaging streets, can help build community by giving neighbors a realm in which to get to know each other, and giving children a safe place to play.
783
ENV-4 | Public Review Draft Environment, Parks & Recreation Element | March 2025 Biological Resources
American Canyon has rich habitat areas in and around the community. The Napa River tidal wetland area lies at the western city boundary. Smaller wetlands are located within the city boundaries, including rivers and streams that traverse the city from east to west. These important ecosystems provide habitat for special-status species that rely on wetland or riparian habitats.

American Canyon is also located alongside critical habitat for a variety of natural species, including the California red-legged frog (Rana draytonii) to the east of the city, and vernal pool fairy shrimp. (Branchinecta lynchi) to the northwest. (Source: New Text)
Justification: The biological resources of any particular development site would be characterized by qualified biologists during the CEQA review process.

What is critical habitat?
Critical habitat, as defined by the
Endangered Species Act, are
specific geographic areas that are
important for the protection
and/or recovery of an endangered
or threatened species.

There are six primary watercourses within the Planning Area: American Canyon Creek, North Slough Creek, Rio Del Mar Creek, Rio Del Mar Creek, No Name Creek, and Fagan Creek. These watercourses have well-defined channels upstream with sparse vegetation due to the streams being dry most of the year. The downstream reaches of the creeks have significant vegetation along banks because of year-round flows mostly generated from development runoff.

Most of the city’s precipitation falls as rain during the months of November through April with the most rainfall in December and January. The mean annual precipitation is between 22 and 23 inches.

Open Space
American Canyon maintains approximately 1,168 acres of open space, including the 642-acre Newell Open Space Preserve, the 24-acre Clarke Ranch open space area, and 513 acres of protected wetlands on the western side of the city (Figure 1). Figure 2 shows land designated as open space in and surrounding the city.

Open Space is managed by several agencies and private individuals within the city and Planning Area. Some of these are listed below:

The City of American Canyon
The City of American Canyon owns and manages several open space resources within the city and Planning Area.

Newell Open Space Preserve
The Newell Open Space Reserve (Newell Open Space) is located east of the city limits. Consisting of 642 acres of steep hills, Newell Open Space is also a working ranch with free-range cattle. The preserve was donated to the City in 1999 by Jack and Bernice Newell. The Land Trust of Napa County holds a conservation easement over the property. The preserve consists primarily of non-native grassland with pockets of oak-bay woodlands and eucalyptus trees and provides habitat for federally listed threatened and endangered plant and animal species including golden eagles, red-legged tree frogs and Tiburon paintbrush. In addition to providing natural habitat and grazing lands, Newell 791
ENV-12 | Public Review Draft Environment, Parks & Recreation Element | March 2025 Open Space is used for recreation by the public and has a system of trails that the City intends to improve and expand.

Clarke Ranch
Acquired by the City in 1999 from the Port of Oakland through CalFed grant funds, Clarke Ranch is a 24-acre parcel of open space adjacent to the Wetlands Viewing Area and Napa River Bay Trail. Today, the property is home to the American Canyon branch of the 4-H Club and a Spirit Horse Riding Center facility. Spirit Horse is an all-inclusive riding program open to riders of all abilities who are facing developmental, emotional, social, and physical challenges. In 2017, the City Council adopted a Master Plan for future improvements at Clarke Ranch.

Napa River Wetlands
The Napa River Wetlands are located on
lands outside the city limits, but owned by
the City of American Canyon and the State
of California. The Wetlands features ten
miles of trails jointly managed by the City of
American Canyon, the California State Fish
and Wildlife Department, and the Napa
County Parks and Open Space District,
including segments of the San Francisco Bay Trail. The Napa River Bay Trail, which opened the first segment in 2010 provides great views of the wetlands and constructed ponds, as well as public access to the Napa River. You can view a video that describes the wetlands HERE.

Watercourses in American Canyon
Major watercourses in American Canyon have been set aside as open space as part of development approvals. These watercourses and uplands are shown on Figure 1.

Golden State Land Conservancy
Canyon Estates Homes is a residentialsubdivision situated east of Newell Drive north of the American Canyon High School. The Canyon Estates project set aside 67 acres to Golden State Land Conservancy for wildlife and habitat conservation.

Napa Logistics Park is an industrial park located south of Napa Airport, east of Devlin Road. In 2013, the Napa Logistics Park set aside a 34-acre wetland 792

ENV-14 | Public Review Draft Environment, Parks & Recreation Element | March 2025 Trail Networks
Napa County and American Canyon enjoys a network of regional trail systems that showcase many of the unique environments and spectacular scenery throughout the valley. From paved riverwalk trails to hikes along the ridge, the combined trail systems listed below provide views, exercise and adventures for everyone.

The City of American Canyon supports trail networks with several regional partners. These include the Napa County Regional Park and Open Space District, the Napa Valley Vine Trail Coalition, the San Francisco Bay Trail, and the Bay Area Ridge Trail Council.

Napa Valley Vine Trail
The Napa Valley Vine Trail is spearheaded by the nonprofit Napa Valley Vine Trail Coalition to construct a 47-mile walking and biking trail system connecting the entire Napa Valley from the Vallejo Ferry terminal to Calistoga. The City of American Canyon adopted the Vine Trail into the General Plan as part of the Bicycle Master Plan in 2012 with minor updates since that time. A total of 47 miles are envisioned when the trail network is complete. As of 2022, 20 miles have been completed within American Canyon.

The Bay Trail
The Bay Trail is spearheaded by the nonprofit San Francisco Bay Trail Coalition to construct over a 500-mile walking and biking trail system to circle the San Francisco Bay. In American Canyon, a Bay Trail segment is located adjacent to Meadow Bay Drive and Wetlands Edge Road. From there, the Bay Trail continues north along the Napa River to the eastern side of the Brazos Railroad Bridge.

Ridge Trail
The Bay Area Ridge Trail Council, a nonprofit organization encompassing representatives from public and private organizations, has sponsored planning for a 550-mile Ridge Trail that would traverse the ridgelines surrounding the San Francisco Bay. The closest Ridge Trail to American Canyon traverses Hiddenbrooke in Vallejo, north to Lynch Canyon, then to Skyline Wilderness Park in the City of Napa.

Parks and
Recreation
The City of American Canyon’s natural beauty makes
outdoor recreation that much more special. The park
system in the Planning Area is comprised of a diverse range of outdoor parks and recreation facilities that serve every segment of our community. The General Plan will guide the City’s future parks and recreation decisions, so they improve over the next 20 years for the benefit of everyone.

Policy Framework
American Canyon Subdivision Ordinance
The Subdivision Ordinance is included in the American Canyon Municipal Code under Title 18. The subdivision ordinance requires parkland to be dedicated or in-lieu fees paid in conjunction with approval of residential subdivisions.

Parks and Community Services Master Plan
This plan is intended to guide the vision and direction and natural amenities and services provided by the Parks and Recreation Department in American Canyon.
799
ENV-20 | Public Review Draft Environment, Parks & Recreation Element | March 2025 Parks and Recreation Needs Assessment
The Parks and Recreation needs Assessment was completed in 2015. The assessment used a statistically valid survey to predict trends and patterns of use and how to address unmet needs in American Canyon and recommended Level of Service Standards to develop appropriate actions regarding recreation programs, parks, trails, open space, building and other amenities.

Quimby Act
The Quimby Act (Government Code Section 66477) allows local governments to require developers to dedicate land, donate conservation easements, or pay fees to fund parkland development. The Quimby Act has a standard of 3.5 acres of parkland per 1,000 residents. The American Canyon General Plan and Parks and Community Services Master Plan identify a local standard for American Canyon at 5.0 acres per 1,000 residents.

American Canyon Bicycle Master Plan
This plan was developed as a component of the Napa Valley Transportation Authority’s Countywide Bicycle Plan Update. The Bicycle Plan is intended to help make American Canyon more safe, convenient and accessible for bicycles within and traveling through American Canyon. American Canyon adopted the Bicycle Plan into the General Plan in 2012.

American Canyon Pedestrian Master Plan
This plan was developed as a component of the Napa Valley Transportation Authority’s Countywide Pedestrian Plan Update. The pedestrian plan is intended to make walking in Napa County more safe, comfortable, convenient and enjoyable for all pedestrians. It strives to improve accessibility for the disabled but does not intend to replace an existing Americans with Disabilities Act (ADA) Transition Plan. American Canyon adopted the Pedestrian Plan into the General Plan in 2017.

Park Classifications:

Mini-Parks are less than one acre in size and not designed for active recreational uses. They do, however, provide passive open space and buffering from adjacent urban development and typically include elements such as walking paths and benches. The City has three Mini-Parks listed below:

Climate Change and Air
Quality
Greenhouse Gas Emissions
Greenhouse gases (GHG) are gases that trap heat in the Earth’s atmosphere and cause changes to the Earth’s climate, including changes to weather and precipitation patterns and increasing global temperatures. The main sources of GHG emissions are the combustion of fossil fuels for transportation and energy. California is a leader in GHG emissions reductions efforts and has adopted aggressive targets for GHG reduction. Primary GHG reduction legislation driving State and city climate action plans include Assembly Bill (AB) 32, Senate Bill (SB) 32, and Executive Order (EO) B-55-18. California has also passed legislation to increase energy efficiency in buildings (Title 24), improve fuel efficiency in vehicles (Advanced Clean Cars Program), and establish the goal of 100 percent carbon neutral electricity by 2045 (SB 100). 809
ENV-30 | Public Review Draft Environment, Parks & Recreation Element | March 2025 Major California Climate Change Legislation
• Assembly Bill (AB) 32 – AB 32 was adopted in 2014 and sets a statewide goal of reducing GHG emissions to 1990 levels by 2020 and requires for the California Air Resources Board (CARB) to prepare a Scoping Plan that outlines the main strategies the State will employ to meet the 2020 target.
• Senate Bill (SB) 32 – SB 32 was adopted in 2017 and is the successor to AB 32. SB 32 requires the State of California to achieve a statewide reduction in GHG emissions of 40% below 1990 levels by 2030. • Executive Order (EO) B-55-18 – EO B-55-18 establishes a new statewide goal of achieving and maintaining carbon neutrality as soon as possible and no later than 2045. Executive orders have not been codified by the State but are binding for State agencies and therefore, must be addressed by qualified GHG reduction plans.
• Executive Order N-79-20 - (EO N-79-20) issued in September 2020 established a statewide goal that 100 percent of in-state sales of new passenger cars and trucks will be zero-emission by 2035, that 100 percent of medium and heavy-duty vehicles in the State be zeroemission by 2045 for all operations where feasible, and that 100 percent of all drayage trucks will be zero-emission by 2035 where feasible. EO N-79-20 also establishes a goal to transition to 100 percent zero-emission off-road vehicles and equipment by 2035 where feasible. EO N-79-20 directs CARB to develop regulations that will help achieve these goals.
• Senate Bill 100 – SB 100 requires 100 percent of retail sales of electricity to California end-use customer by sourced from eligible renewable energy resources and zero-carbon resources by 2045. SB 100 targets the reduction of GHG emissions associated with electrical generation.
• Bay Area Air Quality Management District (BAAQMD) CEQA GHG Emissions Thresholds – thresholds adopted in April 2022 by BAAQMD require a change to the way CEQA GHG thresholds are analyzed in CEQA documents. In summary, a proposed plan or project within BAAQMD jurisdiction should either 1) be consistent with GHG reduction measures of a local qualified Climate Action Plan (CAP), or 2) include and show proof of all the following: all electric buildings, 15 percent vehicle miles traveled (VMT) reduction, and electric vehicle 810

The City of American Canyon has begun a path towards electrification and decarbonization by adopting the Energy Efficiency Climate Action Plan (EECAP) to outline the City’s approach to reduce energy use and energy-related GHG emissions and through joining Marin Clean Energy (MCE).

In 2019, the City Council issued a Proclamation to join with Napa County Jurisdictions dedicated to working together to address climate change through comprehensive, immediate, and sustained action with community organizations, businesses, schools, and regional partners and jurisdictions to educate, mobilize, expand, and accelerate local, regional, and statewide support.

In 2022, the City Council approved a Climate Emergency Resolution (Resolution 2022-07) recognizing that a Climate Emergency exists, and that it threatens our city, state, country, and the planet. The Resolution recognizes the need to provide leadership and services in working with community organizations, businesses, schools, and regional partners and jurisdictions to educate, mobilize, expand, and accelerate local, regional and statewide support for comprehensive, immediate, and sustained action to achieve its goal of net zero climate pollution by or before 2030.

Gaining a nearly carbon-free power mix through MCE makes the transition to a fully carbon-free economy feasible through a shift to electric vehicles and buses, adopting electric appliances, and shifting buildings away from natural gas usage. The goals and policies listed below are intended to move the City further along the path to decarbonization, allowing it to meet the 2045 carbon neutrality goal set by the State.

Air Quality
American Canyon is located in the San Francisco Bay Area Air Basin (SFBAAB) which includes the nine counties surrounding San Francisco Bay. The Bay Area Air Quality Management District (BAAQMD) monitors regional air quality, oversees policies, and adopts regulations to maintain air quality standards for criteria air pollutants and reduce air pollution and GHG emissions for the SFBAAB.

Air quality in American Canyon is generally good. Monitoring in Napa County from 2016 to March 2020 shows particulate matter of less than 2.5 microns exceeds national standard for a few days in the fall some years but is generally within the national and State standards. The area is within State and national standards for concentrations of other criteria air pollutants, such as, nitrogen dioxide, and particulate matter of 10 microns or less.

Introduction
Public Safety in American Canyon includes both natural and manmade hazards and the emergency response to them. The goals and policies of this element are organized around the following topics:
• Emergency Operations
• Fire Safety
• Flooding
• Geologic Hazards and Seismic
• Hazardous Waste and Materials
• Airport and Military Operations
• Climate Change
• Noise
Emergency Response
and Preparedness
There are several guiding documents that help the City of American Canyon prepare for and respond to natural and manmade disasters. The Emergency Operations Plan (EOP) and community emergency preparedness program helps minimize the risk of loss of life or property in the event of a disaster.

In 2020, the American Canyon Fire Protection District and County adopted The Napa County Multijurisdictional Hazard Mitigation Plan (MJHMP), developed in accordance with the Disaster Mitigation Act of 2000 (DMA 2000) and following FEMA’s Local Hazard Mitigation Plan guidance. The MJHMP uses a process where hazards are identified and profiled, the people and facilities at risk are analyzed, and mitigation actions are developed to reduce or eliminate hazard risk. The implementation of these mitigation actions, which include both short and long-term strategies, involve planning, policy changes, programs, projects, and other activities. The MJHMP evaluates hazards such as drought, 826
S-4 | Public Review Draft Safety Element | March 2025
earthquakes and geologic hazards, wildfire, and flood for the City of American Canyon, and assesses how those hazards may change in the future due to climate change.

Emergency Operations Plan
The City of American Canyon Emergency Operations Plan was adopted in 2009 and covers the government responsibilities, initial and long-term response and operations, mutual aid agreements, and funding options for emergency response in American Canyon.

Community Emergency Preparedness
The City manages a comprehensive website containing information, guidance, and instruction on preparing and responding to each type of emergency the residents of American Canyon may anticipate in the future. General preparedness tips and checklists are included on the main page of the website, with links to more specific guidance, in English and Spanish, for earthquakes, flooding, wildfires, power outages, evacuation procedures, and COVID-19 safety practices.

Emergency Communications
Napa County Jurisdictions’ emergency management is organized within the Standardized Emergency Management System (SEMS) and National Incident Management System (NIMS). (Source: Napa County Office of Emergency Services) The Napa County EOP complies with SEMS and NIMS to coordinate with the State Emergency Plan and National Response Framework. Additionally, the City has an established system for warning and alerting the public of an emergency, and for needed coordination with other departments, agencies, organizations, and levels of government. To notify residents of emergencies, the Police and Fire Departments use the Emergency Alert System (NIXLE), integrated public alert & warning system (IPAWS), special broadcasts, the public address system, City website, City Manager’s updates, Nextdoor, Facebook, nonelectronic communications, and sirens. To alert and activate emergency response personnel, American Canyon uses an Emergency Operations Center (EOC) Notification List, which can only be activated by the City Manager, Police Chief, Fire Chief, or Incident Manager when a disaster occurs or threatens to occur in the city.

Emergency Operations Center (EOC)
The Napa County EOC, located at 1535 Airport Blvd, Napa, CA 94558, within the Napa County Sheriff’s Office, is the central coordination point for multi-agency emergency management coordination. The purpose of a multi-agency coordination point is to provide a location to collect and disseminate information, provide a common operating picture of operational area response activities, and facilitate actions necessary to protect residents and property of Napa County during an event. Napa County has developed an EOC Plan as an annex to the County’s EOP, which includes more specific operational guidance and position description for EOC roles. The American Canyon EOC is located at 911 Donaldson Way East.

The EOC exchanges information with governmental and nongovernmental agencies to maintain a comprehensive situational analysis. The EOC provides space and facilities for the centralized coordination of emergency functions (e.g., emergency operations, communications, damage assessment, public information). It is staffed with specially trained personnel and is equipped with a variety of systems and tools that aid in data collection and sharing, resource allocation, and other critical functions. (Source: Napa County Office of Emergency Services)
Evacuation Procedures
Evacuation may be required if a wildfire or earthquake takes place in the vicinity of homes, businesses, or gathering places. American Canyon generally operates using three levels of evacuation alerts: (Source: New Text) • Evacuation Advisory: This is a precautionary notice designed to give residents time to prepare for a possible evacuation.
• Voluntary Evacuation: Those in the evacuation area are strongly urged to leave the area. If they choose to remain, they should be prepared to take action immediately if danger approaches.
• Mandatory Evacuation: Danger is imminent. Those in the evacuation area should find their Emergency Supply Kit and leave the area immediately.

Should they choose to remain, they may be on their own as emergency personnel will not likely be able to help them.

Napa County and incorporated municipalities have partnered with Zonehaven to establish standardized evacuation zones for the entire county. In the past, evacuation zones were different for each incident;zones now remain consistent.

American Canyon consists of eight evacuation zones, as shown in Figure 1. 828

8. SAFETY
Public Review Draft
Safety Element | March 2025| S-7
SB 99 Evacuation Analysis
Evacuation zones have been designated using Zonehaven to facilitate the movement of residents away from impacted areas before or during a disaster or hazard event. In 2019, the State adopted Senate Bill (SB) 99 which requires cities to identify residential developments in any hazard area identified in the Safety Element that do not have at least two emergency evacuation access roads. This allows the City to identify opportunities to improve evacuation capacity and connectivity for vulnerable neighborhoods. Figure 2 identifies residential neighborhoods that have a single access road for entry and exit (i.e., roads that connect to a collector or arterial road by only a single route).

There are currently eight neighborhoods in the city that have been identified as having only a single access road. Residents of these neighborhoods may be at risk during evacuation scenarios and these neighborhoods may pose significant logistical challenges. As a result, policy and implementing actions have been developed to minimize evacuation challenges for these specific neighborhoods. 830

Wildfire Hazards
Wildfires are a common risk for Californians, and Napa County and American Canyon have had several nearby fires in recent history. The combination of highly flammable fuel, long dry summers and steep slopes creates a significant natural hazard for large wildland fires in many areas of Napa County. Wildland fire behavior is based on three primary factors: weather, topography, and fuel.

Similarly, fires that start in urbanized areas can grow into wildland fires.

Wildland/urban interface (WUI) fire hazards are especially pronounced in areas of high structure densities adjacent to undeveloped open space areas or narrow roads with dense vegetation. A WUI fire may result in death, injury, economic loss, and a large public investment in firefighting activities.

From 2000 to 2020, there were 12 wildfires that burned over 1,000 acres in Napa County. In October 2019, the American Fire caused 526 acres of open space in the eastern hills to burn, threatening the city and prompting evacuation advisories. The Atlas Fire and Nuns Fire, both in 2017, burned approximately ten miles north of American Canyon and were part of a series of destructive wildfires that occurred in the same season. Numerous other fires have caused health issues in the community from smoke, and such fire hazards are expected to continue and worsen in the future due to climate change.

The American Canyon Wildfire District provides fire protection services for the City of American Canyon. Direct wildfire risks for American Canyon are mostly on the eastern side of the city, as shown in Figure 3. As of 2020, American Canyon High School and the American Canyon Water Treatment Plant are located in high wildfire intensity zones, and approximately 1,460 people live in moderate to high wildfire intensity zones. While the urbanized areas of the city are not directly susceptible to wildland fires, development on hillsides has increased the number of homes in the wildland-urban interface (WUI) and fire could spread from the hillside area to urbanized areas. 836

Flood Hazards
The Napa River is prone to seasonal flooding from November through April each year, which most severely impacts low-lying properties near the Napa River and its feeder streams. Recorded history indicates there has been recurrent flooding on the Napa River, with the most serious recent floods occurring in 2005, 1997, 1995, and 1986.

Most areas in the 100- and 500-year FEMA flood zones are located on the west side of the city and along the canal that runs east to west across the city, as shown in Figure 4. Flooding may also occur throughout the city during extreme storms, when the stormwater system is overwhelmed and cannot convey water away quickly enough. Most flooding in the city, whether from the flood zones or stormwater system, occurs during extreme storm events and is limited to localized flooding of a few inches to a few feet at most.

Sea Level Rise
Sea level rise is the increase in ocean levels caused by climate change. Rising global temperatures are melting glaciers and ice caps and causing an expansion of sea water. This phenomenon will lead to more extensive coastal flooding during storms and increased coastal erosion. A small area adjacent to the city’s western border is projected to be affected by future sea level rise due to increased flooding from the Napa River. This area includes the American Canyon Wastewater Treatment Plant, Public Works Yard, and pump stations located along Wetlands Edge Road. This flooding would be minimal, mostly exacerbating any issues already present, with expected flooding depths of less than two feet in most storm events.

Dam Inundation
The Napa County MJHMP includes Figure 1-5: Dam Failure Exposure Summary showing the extent of potential inundation risk for American Canyon in the event of dam failure. While the City does have areas within potential inundation areas should a dam fail, the MJHMP has mitigation measures in place to cooperate with other participating jurisdictions in the assessment of local dams and coordination of warning systems if and when necessary. 840

Geologic and Seismic
Hazards
American Canyon is located near several active or potentially active earthquake faults, including the Northern Hayward/Rodgers Creek, Mayacamas, Hunting Creek-Berryessa, West Napa, and Green Valley faults. Numerous earthquakes have occurred in and near Napa County over the last twenty years. Two largescale earthquakes in Napa County caused damage, death, and injuries over the last twenty years. In September 2000, Napa County residents experienced a 5.2 earthquake on the West Napa Fault. Damages were estimated at $30-50 million. 843

8. SAFETY
Public Review Draft Safety Element | March 2025| S-21
American Canyon is in a severe earthquake probability zone. Figure 5 shows fault lines in American Canyon. Seventy-nine critical facilities are located in earthquake hazard areas, and the water and utility distribution systems are vulnerable in the event of a severe earthquake.

Risk of landslides in American Canyon is primarily located in the eastern hills just outside of the city limits. A moderate earthquake could trigger landslides that impact development on the eastern side of the city, especially in the area south of American Canyon Road and east of Flosden Road and along Newell Drive.

Figure 6 shows areas susceptible to landslide in American Canyon.

The 2014 South Napa Earthquake
The South Napa earthquake hit at approximately 3:30 a.m. on August 24, 2014, at a 6.0 on the moment magnitude scale and a maximum Mercalli intensity of VIII (severe), making it the largest bay area earthquake since the 1989 Loma Prieta earthquake. The earthquake was centered four miles northwest of American Canyon and resulted in over 200 people being injured and significant damages to buildings and infrastructure.

Hazardous Materials
A hazardous material is any substance that may be explosive, flammable, poisonous, corrosive, reactive, radioactive, or any combination thereof because of its quantity, concentration, or characteristics. These substances have a variety of uses and are frequently stored and transported but require special care in handling and disposal because of their hazardous nature.

Hazardous material concerns are most likely to occur as part of certain land uses, such as oil and gas, agriculture, or industrial businesses, or through the transport or storage of hazardous materials. Hazardous materials are most often transported along Highways 29, 12, and 37, and on the California Northern railway. The city’s rail yard also has bulk hazardous material storage, and several permitted underground storage tanks are located throughout the city that could potentially cause concern if leaks occur. There are no State or Federally listed hazardous material cleanup sites in American Canyon, but there are five locations that are considered hazardous waste sites due to the materials or uses on the site.

Airport Hazards and
Military Compatibility
The northern city boundary is just south of the Napa County Airport, with industrial buildings closest to the airport and residences located approximately four miles south. The airport was first constructed in 1942 by the Army Corps of Engineers on County-owned land. The airport does not support commercial flights and mostly serves single-engine aircraft, with a 2021 projection of between 210,000 and 260,000 total aircraft operations for the airport. The airport serves general aviation flight activity from small single-engine aircraft to large business jets. Total aircraft operations in 2023 and 2024 were between 65,500 and 68,000 each year. Federal Aviation Administration (FAA) forecasts project this same, steady level of annual aircraft activity through 20491.

Justification: Revised language updates the status of the Napa Airport.

Potential dangers from the airport are mostly limited to the obstruction of airspace near the airport and the risk of aircraft accidents. The airport and surrounding communities adhere to several practices that minimize these risks.

Open Land Requirements
Maintaining open land to be used in the event of an emergency landing is important to maintain the safety of communities surrounding the airport. The Airport Land Use Plan (ALUP) and land use plans of surrounding communities ensure adequate open space is maintained for emergency landings if necessary.

Limiting Surrounding Development
Residential uses are not allowed in areas that may be impacted by significant noise or safety issues from the airport. Maintaining a buffer around the airport where homes are not allowed to be built mitigates potential hazards. 1 Federal Aviation Administration, Terminal Area Forecast, issued January 2024. 851

Climate Change and
Adaptation
Climate change is affecting the bay area in many ways, some obvious and some more subtle. While climate change occurs on a global scale, the effects are felt locally, and local communities do their part to reduce emissions of the greenhouse gases that cause climate change. Rising average temperatures, more days of extreme heat, more occurrences of drought, more risk of severe wildfires, and rising sea levels are already affecting California cities as a result of climate change.

According to models developed by the State of California and the University of Berkeley, increases in temperature will be the most intense effect of climate change. By 2040, the average maximum temperature is expected rise by 2.5°F to 77.7°F, and by 2050, the average maximum temperature will rise by 3.4°F to

74.8°F, and by 2100 it will rise 4.5°F to 75.9°F. Days where temperatures reach

99.0°F or more are likely to occur twice as often each year by 2040, and more than triple to 12 days a year by 2060.

Regional risks such as wildfire and drought will also increase in American Canyon and in the surrounding Napa and Solano Counties. Changes in weather patterns throughout California could occur, leading to times of extreme drought when rainfall and snowfall is reduced, or instances of extreme storms and flooding.

The California Department of Water Resources projects that the Sierra snowpack will decrease by 25 to 40 percent by 2050, reducing available water supplies throughout California and the surrounding states. The increased temperatures and potential for extreme drought will also increase the risk and intensity of wildfires because of dry vegetation and an increased chance of ignition.

Noise
Noise is recurring or ongoing unwanted or intrusive sound, usually generated by vehicular, railroad, or airplane traffic, construction or industrial activity, or disturbances, such as barking dogs, construction, home maintenance activities, or special events and parties. (Source: Story Maps) To manage unwanted noise, the American Canyon Municipal Code Title 8, Chapter 8.12, Community Noise establishes a noise control program that designates the community development director as the City’s noise control officer (NCO) who, along with the police chief, can enforce noise restrictions within the city. Chapter 8.12 prohibits the making of noise that disturbs the peace and quiet of the community or that causes discomfort or annoyance and outlines procedures for measuring problematic noises. The ordinance also sets limits for interior and exterior noise levels near residential uses and for construction activity and lists specific noises that are prohibited in the city. In addition, the Noise Ordinance specifies procedures for obtaining a variance for noise sources restricted by the ordinance. (Source: New Text)
Noise Sources
Many noise issues are managed by careful planning of land use and circulation patterns, ensuring that noise-generators are located away from noise sensitive areas such as homes, schools, and hospitals. The biggest source of noise in American Canyon is vehicular traffic. Other noise sources include aircraft and railroad operations. (Source: New Text)
Most noise issues in American Canyon are from vehicle traffic, especially along Highway 29 and American Canyon Road. The railroad is another source of noise, running north to south parallel to Highway 29. Much of Highway 29 within the city is developed with commercial uses, and many areas with residential or other noise sensitive uses on both roads have fences to buffer roadway noise. (Source: New Text)
Construction activity also typically generates substantial short-term increases in ambient noise levels in the immediate vicinity of construction sites, which can be disruptive to nearby noise-sensitive uses. Figure 7 shows the projected future noise contour map for American Canyon. (Source: Story Maps) 857

Noise Measurement
Noise is generally described in terms of the loudness (amplitude) of the sound and frequency (pitch) of the sound. Noise loudness is measured in decibels (dB). which are based on a logarithmic scale that condenses the range in sound pressure levels to a more usable number range. A weighted decibel (dBA) is an additional measure of sound that adjusts the sound rating scale to levels consistent with the sensitivity range of the human ear. For example, people perceive a sound 10 dBA higher than another sound as being twice as loud, and 20 dBA higher as being four times as loud. Everyday sounds normally range from 30 dBA (very quiet) to 100 dBA (very loud). (Source: New Text) Noise Sensitive Uses
There are some land uses that are more sensitive to noise than others. Noisesensitive land-uses include residential, residential care, child/elder care facilities, schools, places of worship, and hospitals. Consideration of sensitive land use location relative to noise sources is required to make sure noise levels are not disruptive. Residential neighborhoods are the most common noise sensitive areas in American Canyon. Homes are located on the western and eastern sides of the city, mostly away from Highway 29 and the noise-generating areas of the airport and commercial area to the north. Schools, daycares, and assisted living facilities are located within these quieter residential areas, ensuring they are also located away from major noise sources.

Airport Noise
The Napa County Airport is located north of American Canyon, and the Napa County Land Use Commission oversees the expansion and compatibility of the airport with surrounding jurisdictions to ensure noise mitigation and public safety related to airport activities.

The Napa Airport Land Use Compatibility Plan (NALUCP) outlines compatibility criteria to evaluate and coordinate compatible land use planning and decisionmaking at the local, regional, and State levels. The Napa Airport Land Use Compatibility Plan includes guidance on compatible land uses for designated compatibility zones. (Figure 8, Tables 1 and 2).

The NALUCP is incorporated into the General Plan as a standalone document identified as Appendix 3 Napa County Airport Land Use Compatibility Plan. (Source: NALUCP Section 1.4.2, bullet option #3)

9. ENVIRONMENTAL JUSTICE
Public Review Draft Environmental Justice Element | March 2025 | EJ-3 Environmental Justice
The State of California defines Environmental Justice as “the fair treatment of people of all races, cultures, and incomes with respect to the development, adoption, implementation, and enforcement of environmental laws, regulations, and policies.” Fair treatment means that no group of people should bear a disproportionate share of the negative environmental consequences resulting from industrial, governmental, and commercial operations, and policies.

Today, and throughout much of California and United States history, communities with lower incomes, lower levels of education, and higher proportions of minority residents often bear a disproportionately large burden of exposure to environmental hazards. These environmental inequities are largely a result of land use policy and zoning regulations (e.g., residential uses located adjacent to industrial uses). The environmental justice goals, polices, and implementation programs in this Element seek to address these systemic inequities.

The Planning for Healthy Communities Act of 2016 (Senate Bill 1000) was established to address the role of environmental justice in local and regional planning practice. Through Senate Bill 1000, cities and counties are required to identify environmental justice communities (called “disadvantaged communities”) within their planning area and incorporate environmental justice related goals and policies into their general plans. According to the Bill, environmental justice goals and policies could be integrated into several sections of a general plan or created as a standalone element. The City of American Canyon created this standalone element to address environmental justice goals, policies, and objectives for the community consistent with State law. As of 2022, there are no disadvantaged communities within the City of American Canyon.

Additionally, Government Code Section 65302.10 requires that all general plans identify and analyze Disadvantaged Unincorporated Communities (DUCs) outside of a city’s boundaries but within or adjacent to a city’s sphere of influence (SOI). DUCs are defined as inhabited unincorporated areas with 10 or more housing units and a median household income that is less than 80 percent Racial and Ethnic Diversity
The city is home to a variety of
races and cultures. Diversity is the
representation of different
groups, and in American Canyon
no single US Census-reported race
category makes up more than 40
percent of the local population
total. About four in ten residents
are Asian, three in ten are White,
and almost one in ten are Black.

About one quarter of residents’
report being ethnically Hispanic.

Relationship to Other General Plan Goals, Policies,
and Implementation Programs
State law requires the General Plan, and all individual elements collectively form an “integrated, internally consistent, and compatible statement of policies.” The goals, policies, and programs of this Justice Element are consistent with and build upon the goals, policies, and programs contained in other elements of the General Plan. The goals, policies, and programs established in this Element seek to reduce health risks in American Canyon through strategies such as reducing pollution exposure, improving air quality, and promoting public facilities, food access, safe and sanitary homes, and physical activity; promote civil engagement in the public decision-making process; and prioritize improvements and programs that address the needs of today and the future.

Many policies that address environmental justice impacts and improve the quality of life for American Canyon residents are already present in other General Plan elements. EJ-Table 1, below, provides a list of these policies. The goals, policies, and programs in the Environmental Justice Element aim to fill gaps and ensure the General Plan fully addresses community member needs.

Background
California law defines “disadvantaged communities” as areas most afflicted with a combination of economic, health, and environmental burdens. As a result, they are more likely to suffer a lower quality of life and increased health problems. To identify local disadvantaged communities, the Governor’s Office of Planning and Research (OPR) recommends utilizing the California Communities Environmental Health Screening Tool (CalEnviroScreen) to identify designated disadvantaged communities.

CalEnviroScreen 4.0Methodology
Developed by the Office of Environmental Health Hazard Assessment (OEHHA), the CalEnviroScreen tool identifies disadvantaged communities throughout California. In October 2021, OEHHA released CalEnviroScreen 4.0 which was used to prepare this Element. CalEnviroScreen 4.0 uses existing environmental, health, and socioeconomic data to rank census tracts based on 20 distinct indicators. The 20 indicators are grouped into four indicator categories which are summed into two primary data groupings (see EJ-Table 2):

EJ-8 | Public Review Draft Environmental Justice Element | March 2025 To identify potential disadvantaged communities, CalEnviroScreen produces a percentile ranking of each census tract to demonstrate burdens present in that tract relative to the rest of the State. The percentile ranking is calculated by combining the indicator scores for each census tract in EJ-Table 2. In general, the higher the CalEnviroScreen score, the more impacted a community is by pollution burdens and population vulnerabilities. For example, a 80th percentile ranking for a census tract would mean that the census tract is in the top 20 percent of all CalEnviroScreen scores statewide. Designated disadvantaged communities are those communities that scored within the highest 25 percent of census tracts across California (overall CalEnviroScreen percentile scores of 75 or higher).

Census Tractsin American Canyon
The American Canyon planning area is comprised of five census tracts. A census tract is a geographical region defined for the purpose of documenting population data. Sometimes census tracts coincide with a city limit, whereas others exist entirely within an unincorporated county. Occasionally a census tract will exist in both the unincorporated county and city limits. Three of the five American Canyon planning area census tracts include unincorporated Napa County areas. See EJ-Table 3, below, and EJ-Figure 1.

Based on 2019 data, American Canyon has no census tracts that are at or below the statewide median income1. Fortunately, as shown in EJ-Table 4, and EJFigure 2, no census tracts within the American Canyon planning area received an overall CalEnviroScreen percentile score at or above the 75th percentile. This means there are no identified disadvantaged communities within the city or Planning Area. Census tracts 6055201003 and 6055201005 received the highest CalEnviroScreen scores of 62 and 63, respectively. As shown on Figure EJ-1, Census tracts 6055201003 and 6055201005 encompass very large areas outside the City Limits and include industrial uses in the northern areas of the city, around Napa Airport, and vineyards northeast of the city. In contrast, census tracts 6055201004, 6055201006, and 6055201007 which are limited to American Canyon city limits and the open space hill immediately east of the La Vigne neighborhood received the lowest scores with an average overall CalEnviroScreen score of 31.

Public Review Draft Environmental Justice Element | March 2025 | EJ-11 by measuring a range of pollution exposure and environmental indicators that people may encounter within their environment (see EJ-Table 2 for a list of indicators).

Fortunately, no census tracts in American Canyon received a pollution burden percentile score in or above the 75th percentile. Census tracts with the lowest pollution burden are primarily located in American Canyon, while census tracts with the highest pollution burden percentiles are located in the northern census tracts that extend well beyond the city limits into Napa County (see EJ-Figure 2).

Population Characteristics
Table EJ-Table 4 presents the CalEnviroScreen population characteristics burden scores for all associated tracts in American Canyon. The population characteristics burden score is calculated using a range of sensitive population and socioeconomic factor indicators. Certain population characteristics and socioeconomic factors are often related to health conditions such as asthma, low-birth weight, and cardiovascular disease. Socioeconomic factors such as lower educational attainment, linguistic isolation, poverty, unemployment, and housing burden are often found in populations that also have a higher risk of health conditions (see EJ-Table 2 for a list of indicators). No census tracts in American Canyon received a population characteristics burden percentile score in or above the 75th percentile.

S-Table 1: Compatibility Zone Definitions
Zone A Runway Protection Zone: Dimensioned to encompass the current and future Runway Protection Zones for the runways of the Napa County Airport, as defined under FAA regulations and shown on Figure 8. The zones also include areas lateral to the runway. These areas are regularly overflown by aircraft below 50 feet above the ground. For this reason, these areas are considered high risk with regard to accident potential and any structures, buildings, trees or obstacles may create a flight hazard. These areas are also affected by high noise levels.

Zone B Approach/Departure Zone: This zone is defined as the areas where aircraft will be below 100 feet above ground level as determined by the type of approach anticipated for that runway.

Approach slopes are designated on the Airport Compatibility Zones map, Figure 8. These areas are affected by substantial risk of accident potential due to the frequency of overflights at low altitudes. Noise levels are generally high with frequent loud single-events.

Zone C Extended Approach/Departure Zone: This zone is defined as the area where aircraft will be below 300 feet above ground level as determined by the type of approach. The low altitude of the aircraft in these areas indicates moderate to high risk of accident potential. Properties in this zone will be affected by substantial noise.

Zone D Common Traffic Pattern: This area is defined by the flight pattern for the Napa County Airport as illustrated on Figure 8. These areas are routinely overflown by aircraft operating to and from the airport with frequent single-event noise intrusion. Overflights in these areas can range from near the traffic pattern altitude (about 1,000 feet above the ground) to as low as 300 feet above the ground. Accident risk varies from low to moderate. Areas where aircraft are near pattern altitude (e.g., downwind leg) have the lowest risk. In areas where aircraft are at lower altitudes (especially on circle-to-land instrument approaches) a moderate level of risk exists.

Zone E Other Airport Environs: An airport’s influence area often extends beyond the typically defined compatibility zones during busy traffic hours and when larger aircraft are in the pattern. Aircraft overflights can occur anywhere in these areas when aircraft are departing or approaching an airport. Overflight annoyance is the 883

1. Residential land use and zoning designations are considered incompatible uses within the traffic pattern area (Zones A, B, C, and D) where aircraft overflights are frequent and at low altitude. The residential restrictions do not apply to residential uses allowable under agricultural land use and zoning designations.

2. The use should not attract more than the indicated number of persons per net acre.

Net acreage is the total site area inclusive of parking areas and landscaping, less the area dedicated for streets. These densities are intended as general planning guidelines 885

8. SAFETY
Public Review Draft Safety Element | March 2025| S-43
to aid in determining the acceptability of proposed land uses. Clustering of development within the density parameters should be encouraged to protect and provide open land/safety areas. However, in Zones A, B, and C the density of any one acre of a parcel should not exceed twice the indicated number of people per acre.

3. Dedication of an avigation or overflight easement or deed notice is required as a condition of new development within all zones. Also, height limit restrictions are applicable to structures and trees in all zones in accordance with Federal Aviation Regulation Part 77 and local ordinances. Uses which may be hazardous to flight are prohibited in all zones.

4. These uses typically can be designed to meet the density requirements and other development conditions listed.

5. These uses typically do not meet the density requirements and other development conditions listed. They should be allowed only if a major community objective is served by their location in this zone and if mitigation measures (i.e., noise attenuation) are incorporated that will minimize potential conflicts.

6. NLR = Noise Level Reduction; I.e. the attenuation of sound level from outside to inside provided by the structure. Noise level reduction measures may be required in areas with high single-event noise levels and where noise-sensitive uses (schools, libraries, etc.) are proposed. Refer to Appendix C for criteria and noise attenuation measures.

7. Maximum residential densities in accordance with local adopted General Plans and zoning designations. Consideration should be given to the proximity of flight patterns, frequency of overflight, terrain conditions, and type of aircraft in determining acceptable locations of residential uses. Referral to the ALUC for review of development plans prior to approval is recommended.

8. The purpose of these criteria is to provide a basis for determining those land uses which are compatible with airport activities. Specific land uses will be allowed only in they are also consistent with applicable General Plan policies and zoning ordinances.

9. All lands in Zone A are either within the Airport’s boundaries or are designated for acquisition in the Airport Master Plan.

10. Includes objects that penetrate FAR Part 77 surfaces, uses that would attract large numbers of birds (e.g., landfills), and uses that would create smoke, glare, distracting lights, or electronic interference.

11. Avigation easements will be required in lieu of overflight easements or deed notices where there is an appropriate public agency to review them. 886

S-8.4: Sensitive Facilities. Ensure appropriate noise mitigation is incorporated into the design of noise- sensitive facilities. (Source: New Policy)
S-8.5: Site Design. Minimize noise impacts to adjacent noise-sensitive land uses in site planning and project design. (Source: New Policy)
S-8.6: Roadway Noise. Encourage nonmotorized transportation alternatives for local trips and decrease excessive motor vehicle noise by implementing traffic-calming road design, lateral separation, natural buffers, and setbacks. (Source: New Policy) S-8.7: Highway Noise. Continue to coordinate with California Department of Transportation (Caltrans) and the NVTA to complete the American Canyon SR 29 Corridor Improvement Project. (Source: New Policy)
S-8.8: Noise Complaints. The Noise Control Officer will continue to monitor and enforce noise complaints from residents, seek to resolve concerns where feasible, and make the enforcement process accessible to the general public. (Source: New Policy) S-8.9: Mobile Noise Sources. Minimize exposure of sensitive receptors to noise from roads through land use decisions, by encouraging the siting of sensitive noise receptors away from high traffic roadways. (Source: New Policy)
S-8.10: Noise Mitigation Measures. Require heavy trucks to use designated truck routes that avoid residential and other sensitive land uses to the maximum degree feasible. When not feasible, investigate noise mitigation strategies such as noise barriers or truck travel restrictions, especially in areas of concern such as along American Canyon Road. (Source: New Policy)
S-8.11: Railroad Noise. Minimize exposure of sensitive receivers to railroad-related noise and vibration through land use decisions 888

and, as appropriate, use of setbacks and/or noise insulation for new development. (Source: New Policy)
S-8.12: Construction Noise. Minimize exposure of sensitive receivers and enforce the limits in Section 8.12 of the municipal code for construction noise and vibration through methods such as restricting construction to daytime hours, use of sound barriers and/or other methods to dampen noise from construction
equipment, and public notification prior to construction activities. (Source: New Policy)
S-8.13: Cross-Jurisdictional Coordination. If noise concerns related to the California Northern Railroad (CFNR) or Napa County Airport arise, coordinate with those entities to develop and implement appropriate responses. (Source: New Policy)
S-8.14: Residential Outdoor Mechanical Equipment. Require air conditioning units and pool equipment within residential areas be designed and sited in a manner that does not intrude upon the peace and quiet of adjacent noise-sensitive uses. (Source:

Existing Policy 11.2.3)
S-8.15: Vibration Impacts. Require project specific vibration impact assessments for projects involving the use of vibration generating equipment such as pile drivers and vibratory rollers that could generate groundborne vibration levels. For projects with significant vibration impacts, require feasible mitigation measures to reduce ground vibration levels and exposure to sensitive receptors. (Source: New Policy)
