2. Project Description
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 2-32 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 Adaptation and Resilience Strategies and Measures
The Adaptation and Resilience measures were developed through a process of integrating community priorities with technical analysis. Extensive community engagement with residents, youth, and local organizations was crucial, as it helped identify the most pressing climate concerns in the area, such as extreme heat, poor air quality, flooding, and challenges with access to safe transportation. These direct insights from the community about how they experience climate risks were used to inform potential solutions.

This qualitative input was then paired with technical data on local hazards, existing assets, and factors such as feasibility and equity. The goal was to create a set of measures that are not only practical and coordinated but also address multiple hazards simultaneously. This integrated approach ensured that the final measures effectively reflect the community's understanding of climate risks while providing a practical framework for the City's coordinated response.

Measures were screened and prioritized using the following criteria:

1. Community engagement findings. Strategies were grounded in the priorities and lived experiences of Maywood residents, as identified through two phases of community engagement led by the City and the Institute for Local Government (ILG). Surveys, youth focus groups, advisory committee meetings, and stakeholder interviews helped identify key local concerns such as extreme heat, air quality, clean transportation, and water reliability. These findings guided the design and emphasis of each adaptation measure to reflect community-identified needs and values.

2. Alignment with the City’s Hazard Mitigation Plan. Measures were cross-referenced with actions in the City’s Hazard Mitigation Plan (HMP) to ensure consistency and to leverage existing commitments and funding pathways. Strategies indicated as High or Medium priority in the HMP were considered foundational to the CAARP’s adaptation framework, particularly for hazards such as flooding, extreme heat, and seismic events.

3. Multi-hazard resilience benefits. Preference was given to actions that improve resilience across multiple hazard types. For example, measures that address both heat and air quality (such as urban tree planting or green infrastructure) were prioritized because they provide overlapping public health and environmental benefits.

4. Focus on high-risk hazards. Results from the qualitative risk matrix were used to identify which climate hazards pose the greatest combined threat in terms of likelihood, exposure, and consequence.

Measures that directly reduce vulnerability to these highest-rated hazards—such as extreme heat, flooding, and drought—were given greater emphasis.

5. Equity and feasibility considerations. Informed by community engagement, the prioritization process also accounted for social equity—ensuring that measures address the needs of renters, lowincome households, youth, and linguistically isolated residents. Feasibility, including cost, ease of implementation, and potential for partnerships, was also evaluated to ensure measures are both impactful and achievable within Maywood’s resources and institutional capacity.

6. Avoid duplication. Adaptation options were reviewed to ensure that they add value and do not duplicate measures already addressed elsewhere in the plan. For example, many of the actions in the Water Conservation and Reuse measures in Chapter 4 of the CAARP help to address drought. Where needed, the Adaptation and Resilience measures include additional actions that address drought (e.g., Measures A3 and A4).

Table 5, Maywood CAARP Adaptation and Resilience Strategy and Measures, provides a summary of all of the CAARP's Adaptation and Resilience measures and how each will help the City prepare for and respond to the impacts of climate change. Key implementing actions for each measure outline the specific steps to achieve the City's climate preparedness goals, including developing programs, hosting outreach and education activities, coordinating with community partners, conducting studies, and exploring incentives and regulatory updates. These actions identify what must be done within both the community and municipal operations, when applicable, to ensure successful implementation.

Integrating Climate Vulnerability, VMT Reduction, and
Adaptation Strategies
The CAARP establishes a comprehensive framework for climate action by deeply integrating GHG reduction goals with its dedicated Adaptation and Resilience strategies (detailed in Chapters 5 and 6 of the CAARP). To ensure that the CAARP’s mobility measures actively support resilience, a specific alignment matrix was developed to coordinate various actions, as shown in Table 6, Maywood CAARP VMT Reduction Strategies, Vulnerability, and Adaptation Matrix. This matrix serves as a critical technical tool, providing a high-level summary of how the City's identified five key climate vulnerabilities— including 1) Extreme Heat, 2) Air Pollution, 3) Extreme Storms and Stormwater Flooding, 4) Drought, and 5) Vector-borne Diseases—relate to the proposed measures designed to reduce VMT.

This integration ensures that transportation and land use decisions are viewed not just through an emissions lens, but also through the lens of community safety and climate preparedness, particularly for vulnerable populations. This integrated matrix is organized around each specific climate vulnerability to clearly show the interconnectivity of the CAARP’s policies, highlighting which adaptation strategies are supported by which VMT reduction efforts.

The VMT reduction measures summarized and referenced in the matrix of Table 6 fall into five key, actionable categories, as shown in Table 7, CAARP Reduction Measures by Category, below.

By connecting the reduction of vehicle use (and its associated air pollution) to specific resilience goals (like mitigating extreme heat impacts or improving public health outcomes), the CAARP ensures that the policies are mutually reinforcing. This coordinated approach maximizes the environmental, equity, and public health benefits for the Maywood community.

MAYWOOD CAARP VMT REDUCTION STRATEGIES, VULNERABILITY, AND ADAPTATION MATRIX Measure/ Impact Vulnerable Populations Adaptation Strategies Extreme Heat
Increasing frequency of extreme heat days worsens urban heat island effects, impacting vulnerable populations and non-driving modes of transportation High:

Extreme heat strains transportation infrastructure and is heightened by pavement and concrete. Extreme heat
discourages active transportation and public transit usage.

Land Use:

Increased densities in Maywood could contribute to heat island effect depending on materials used.

Trip Reduction Programs:

Extreme heat makes alternatives to driving less desirable for choice riders.

Parking or Road Pricing/Management:

Increased temperatures makes driving more appealing than transit, contributing to increased vehicle ownership and parking demand.

Neighborhood Design:

Active transportation infrastructure becomes less
accessible and harder to use with increased temperatures.

Transit:

Transit usage becomes less desirable and a health risk if stops are not close by, lack shade and amenities, and have low frequency routes.
• Children
• Seniors
• Homeless Individuals
• Lacking Vehicle Access
• Lacking Health Insurance
• People with Disabilities
• Linguistically isolated individuals
• Renters
• Lower Income
Individuals who are vulnerable to health risks, whether financially or physically, are at an amplified risk for heat related illness. Exposure is further exacerbated for
populations who rely on transit and active modes of
transportation without access to a car or home. Lower
income households and renters may face additional burdens from the increased costs associated with high temperatures.

When combined, the intersection of these vulnerable
populations leaves individuals at a higher exposure to heat related illness.

Land Use:
• Climate-resilient building designs
• Incorporate permeable and reflective pavements
• Incorporate reflective roofs and materials
Trip Reduction Programs:
• Consider heat protection as part of travel planning
and infrastructure design (paths, transit stops)
Neighborhood Design:
• Consider shade and heat exposure when
planning active transportation infrastructure
• Incorporate cooling center with mobility hub
Transit:
• Develop transit shelters and shade
• Increase frequency and reliability to reduce heat
exposure
• Provide multilingual materials regarding service
changes and resilience/adaptation strategies
• Coordinate transit routes and stops with cooling
center locations, open space with landscaping
and shade, and essential services like schools,
medical offices, civic facilities, and grocery stores
Air Pollution
Air pollution from traffic, exacerbated by single occupancy vehicles, leads to respiratory and cardiovascular health risks.

High:

Vehicle trips within in and passing through Maywood
heavily exposes residents to pollutants at an increased health risk. Air pollution exposes residents and nonmotorized modes of transportation to greater levels of pollutants.

Land Use:

Increased land use quantities can lead to an increase of vehicles and thus air pollutants, while with mixed-use and • Children

• Lacking Health Insurance
• People with Disabilities
• Homeless Individuals
• Lacking Vehicle Access
• Lower Income
Individuals who are vulnerable to health risks, whether financially or physically, are at an amplified risk for air All measures reduce VMT and therefore air
pollutants
Land Use:
• Develop mixed-use housing to encourage active
transportation for short trips
• Develop transit-oriented developments to
encourage public transit usage
• Incorporate air filtration in new developments

Trip Reduction Programs:

Reduces air pollution by encouraging other modes of
transportation.

Parking or Road Pricing/Management:

Reduces air pollution by discouraging driving.

Neighborhood Design:

Encourages non-motorized modes of transportation but can expose users to higher levels of air pollution.

Transit:

Transit usage may leave users exposed to greater levels of pollutants. Buses can expose users to pollutants depending on the fuel used.
pollution related illness. Exposure is further exacerbated for populations who rely on transit and active modes of
transportation without access to a car or home. When
combined, the intersection of these identities leaves these individuals at a higher exposure to respiratory and
cardiovascular related illness. There is generally a
disproportionate impact on vulnerable communities.

Transit:
• Electrify Maywood Express and other public
services (schools, LA County)
Extreme Storms and Stormwater Flooding
Aging stormwater infrastructure is insufficient to handle extreme rainfall, causing localized flooding and impacting transit services Medium:

Flooding disrupts travel and transit while damaging
infrastructure. Lack of drainage and pavement contribute to flood susceptible conditions. Rain water also contributed to hazardous driving conditions. Although the City is not in a designated flood hazard zone, flooding can still occur and impact emergency evacuation routes.

Neighborhood Design:

Active transportation infrastructure becomes inaccessible during floods and may be damaged.

Transit:

Transit services may be unavailable during floods leaving vulnerable populations without transportation options.
• Children
• Seniors
• Homeless Individuals
• Lacking Vehicle Access
• People with Disabilities
• Renters
• Lower Income
Individuals who rely on transit and active modes of
transportation without access to a car or home are
vulnerable to disruptions from flooding. Lower income
households and renters may face additional burdens from the increased costs from damage, mold, and even
displacement. Disruption of transportation services and infrastructure impacts workers and people who need to travel in emergency situations.
• Improve stormwater infrastructure to allow better
drainage along streets
• Incorporate green infrastructure and permeable
materials when possible
Transit:
• Develop transit shelters to provide protections
from storms
• Provide multilingual materials regarding service
changes and resilience/adaptation strategies

2. Project Description
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 2-39 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 Measure/ Impact Vulnerable Populations Adaptation Strategies Drought
Reduced groundwater and imported water reliability threaten long-term water supply, increasing costs for residents.

Medium-High:

Drought has minimal impacts directly on the transportation system. Drought can have secondary affects on
developments that encourage other modes of travel by
increasing costs.

Land Use:

Increasing density increasing strain on the water supply which is exacerbated during a drought. Concerns over
water may limit higher densities or mixed-use and transit oriented developments.
• Lower Income
Vulnerable populations include those who are lower income and cannot pay for higher water prices. Water conservation may leave vulnerable populations at risk.
• Improve stormwater infrastructure to allow better
drainage along streets
• Incorporate green infrastructure and permeable
materials when possible
Transit:
• Continued efforts to reduce VMT and vehicle trips
can help reduce water consumption, vehicle
pollution, and impermeable services
Vector-Borne Diseases
Reduced groundwater and imported water reliability threaten long-term water supply, increasing costs for residents.

Medium:

Vector-borne diseases has minimal connection to
transportation. Impacts may include greater exposure risk to active transportation and public transit users.

Neighborhood Design:

Active transportation usage may contribute to greater
exposure to vector borne diseases.

Transit:

Transit usage may contribute to greater exposure to vectorborne diseases. • Children
• Seniors
• Homeless Individuals
• Lacking Vehicle Access
• Lacking Health Insurance
• People with Disabilities
Active transportation and public transit usage may contribute to greater exposure to vector-borne diseases. Transit
dependent population or health vulnerable populations may be impacted more.

Adaptation strategies are generally unrelated to
transportation systems

The CAARP, is a policy document designed to reduce GHG emissions and enhance community resilience to climate change. The CAARP itself does not propose land use, zoning changes, or any specific physical development. The incorporation of the CAARP’s Adaptation and Resilience Measures are designed to contribute positively to the urban environment, effectively creating new, valued scenic/aesthetic resources such as tree planting, urban greening, and shade structures which is a top priority for resilience to extreme heat. Measure A3 will increase the tree canopy and shade coverage citywide and along active transportation corridors. Similarly, Measure A4 would involve integrating features like bioswales, permeable paving, and landscaping into the urban environment. Measures A3 and A4 would directly enhance the quality and visual appeal of public spaces in the City.

While future physical projects would be implemented under the CAARP’s various strategies, such as the expansion of the bicycle and pedestrian network (Measure M3), these future CAARPrelated projects would be limited to existing developed/urbanized areas. Furthermore, such future individual projects implemented under the CAARP would be subject to a separate environmental review under CEQA, ensuring consistency with the City’s existing zoning and design regulations relative to visual quality, character, and overall compatibility. Because the CAARP is a policy document and does not propose specific physical developments, and any assessment of impacts of future projects consistent with the CAARP would be speculative at this time, the Project would not have a substantial adverse effect on a scenic vista or damage scenic resources. Therefore, the Project would result in a less than significant impact and no mitigation measures would be required.

City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-5 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 c) Less Than Significant Impact. The CAARP's implementation would be consistent with the City’s General Plan, which guides long-term planning and development. The CAARP would encourage sustainable urban development, such as infill and mixed-use projects, which are also supported by the Housing and Land Use Elements of the General Plan. By promoting development in existing neighborhoods and along transit corridors, the CAARP aligns with policies that ensure new housing is sensitive to existing neighborhood character. The CAARP’s focus on a vibrant, walkable City contributes to a desirable urban character. Specifically, the CAARP’s GHG Reduction strategy, Smart Mobility and Active Transportation (M), would include measures to improve street connectivity, provide pedestrian network improvements, and expand bicycle facilities. The CAARP’s Adaptation and Resilience strategies further reinforce this positive contribution to urban character, making the Project highly beneficial to the City’s visual quality. Specifically, Measure A3 ensures that improvements to the pedestrian and bicycle network (Measure M3) are accompanied by increased shading and landscaping, directly enhancing the aesthetic experience of public views along these corridors. The integration of Measure A3 addresses the community’s priority regarding safe and shaded public spaces and ensures that new infrastructure is designed not only for function but also for durability and quality, supporting the Land Use Element’s policy of establishing and enforcing development standards.

The proposed CAARP measures would enhance the health, safety, and general welfare of the community by improving air quality and creating a more visually appealing environment, which helps maintain neighborhood character. The Project itself does not propose or authorize specific physical development projects. Any individual projects implemented as part of the CAARP would be required to undergo a separate environmental review and would be evaluated for consistency with the City’s General Plan and zoning ordinances. Therefore, the Project would not conflict with these regulations and would result in a less than significant impact related to a conflict with applicable zoning and other regulations governing scenic quality, and no mitigation measures would be required.
d) Less Than Significant Impact. The CAARP is a policy document that outlines a strategic roadmap for reducing GHG emissions and enhancing community resilience. The CAARP would not create new sources of light or glare as no specific development changes are proposed.

However, its implementation would lead to CAARP-related projects that would include physical changes, such as the installation of solar panels on rooftops and public spaces (Measure E2) or EV charging infrastructure (Measure V1). These individual projects would be subject to a separate environmental review under CEQA and would be expected to comply with existing City regulations and standards, including those related to light and glare. For example, the installation of solar panels on rooftops and public spaces (Measure E2) would be required to comply with the City’s existing regulations regarding lighting and reflective materials.

In addition, the CAARP’s Adaptation and Resilience strategies recognize that improving lighting quality is necessary to increase the usability and safety of public spaces and critical facilities, especially during extreme weather events or at night. The implementation of active transportation projects (Measure M3) would involve strategic installation of new, high-quality and well-shielded exterior lighting to improve safety and access, directly addressing the community’s concerns

The incorporation of the adaptation and resilience strategies ensures that while new lighting may be installed, it is done intentionally to improve safety and in compliance to existing City standards to prevent adverse light or glare impacts. Therefore, the Project would not create a new source of substantial light or glare which would adversely affect day or nighttime views in the area and Project impacts would be less than significant and no mitigation measures would be required.

II. AGRICULTURE AND FORESTRY RESOURCES —
In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. In determining whether impacts to forest resources, including timberland, are significant environmental effects, lead agencies may refer to information compiled by the California Department of Forestry and Fire Protection regarding the state’s inventory of forest land, including the Forest and Range Assessment Project and the Forest Legacy Assessment project; and forest carbon measurement methodology provided in Forest Protocols adopted by the California Air Resources Board. Would the project:
a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps
prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to nonagricultural use? ☐ ☐ ☐ ☒
b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? ☐ ☐ ☐ ☒

e) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use?
☐ ☐ ☐ ☒
Discussion
a) No Impact. Based on a review of the California Department of Conservation (DOC) Farmland Mapping and Monitoring Program (FMMP), the City is designated as Urban and Built-Up Land.9 There is no Prime Farmland, Unique Farmland, or Farmland of Statewide Importance in the City.

Further, the CAARP does not propose physical changes that would affect agricultural land.

Therefore, the Project would not result in the conversion of Prime Farmland, Unique Farmland, or Farmland of statewide importance to non-agricultural use and no impact would occur, and no mitigation measures would be required.
b) No Impact. The City does not contain any agricultural land uses within a Williamson Act Contract.10,11 The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City. Thus, the Project would not conflict with existing zoning for 9 DOC. 2025. California Important Farmland Finder. Available at: https://maps.conservation.ca.gov/dlrp/ciff/, accessed July 31, 2025.

c) No Impact. There is no land zoned for forest land, timberland, or timberland production in the City.12 Thus, the Project would not conflict with existing zoning for or cause rezoning of forest land, timberland, or timberland production and no impact would occur, and no mitigation measures would be required.
d) No Impact. As mentioned above, the City does not have any land designated or zoned for forest use.13 Thus, the Project would not result in the loss of forest land or conversion of forest land to non-forest use and no impact would occur, and no mitigation measures would be required. e) No Impact. As mentioned above, the City is urbanized and built up.14 There are no forest lands within the City, as defined by Public Resources Code (PRC) Section 12220(g), nor are there any timberlands defined by PRC Section 4526.15 Thus, the CAARP does not propose land use, zoning, or physical changes in the City, which due to their location or nature, would result in conversion of Farmland to non-agriculture use or conversion of forest land to non-forest use, and no impact would occur, and no mitigation measures would be required.

III. AIR QUALITY —
Where available, the significance criteria established by the applicable air quality management district or air pollution control district may be relied upon to make the following determinations. Would the project:
a) Conflict with or obstruct implementation of the applicable air quality plan? ☐ ☐ ☒ ☐
b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable federal or state ambient air quality standard?
☐ ☐ ☒ ☐
c) Expose sensitive receptors to substantial pollutant
concentrations? ☐ ☐ ☒ ☐
d) Result in other emissions (such as those leading to
odors) adversely affecting a substantial number of
people?
☐ ☐ ☒ ☐
Discussion
a) Less Than Significant Impact. The City is located within the South Coast Air Basin (Basin). Air quality planning for the Basin is under the jurisdiction of the South Coast Air Quality Management District (SCAQMD). The SCAQMD adopts Air Quality Management Plans (AQMPs) that serve as a regional blueprint to develop and implement emissions reduction strategies and that demonstrate attainment of the National Ambient Air Quality Standards by the timelines specified in the Clean Air Act (CAA). The SCAQMD adopted the 2022 Air Quality Management Plan (2022 AQMP)16 on December 2, 2022. On January 26, 2023, the California Air Resources Board (CARB) adopted Resolution 23-4, which directs the CARB Executive Officer to submit the 2022 AQMP to the United States Environmental Protection Agency (USEPA) for inclusion in the California State Implementation Plan (SIP) to be effective, for purposes of federal law, after notice and public hearing as required by Section 110(l) of the CAA and 40 Code of Federal Regulations Section 51.102 and approval by the USEPA. USEPA approval has not yet occurred.

The goal of the 2022 AQMP is to provide a regional roadmap for the Basin to achieve the 2015 8- hour ozone level established by the National Ambient Air Quality Standards (NAAQS) (70 parts per billion [ppb]). The 2022 AQMP builds upon measures in place from previous AQMPs and also includes additional strategies, including the regulation and accelerated deployment of cleaner technologies (e.g., zero emissions technologies and low nitrogen oxides [NOx] technologies in other applications), best management practices (BMPs), co-benefits from existing programs (e.g., climate and energy efficiency), incentives, and other CAA measures.

The AQMP strategies are developed, in part, based on regional population, housing, and employment projections prepared by the Southern California Association of Governments (SCAG). The 2022 AQMP was prepared to accommodate growth, reduce the high levels of 16 SCAQMD, 2022 Air Quality Management Plan, 2022.

City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-10 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 pollutants within the areas under the jurisdiction of SCAQMD, return clean air to the region, and minimize the impact on the economy. Projects that are consistent with the assumptions used in the AQMP do not interfere with attainment because the growth is included in the projections utilized in the formulation of the AQMP. Thus, a projects use and activities that would not conflict with the applicable growth projections and control strategies used in the development of the AQMP would not jeopardize attainment of the air quality levels identified in the AQMP, even if a project, use, or activity would individually exceed the SCAQMD’s numeric significance thresholds.

The CAARP is a policy document and does not propose the construction and operation of physical development that would generate criteria or ozone precursor air pollutant emissions. The purpose of the CAARP is to reduce the City’s community-wide GHG emissions and to enhance the community’s resilience to the anticipated impacts of climate change. Specifically, Measure A1 would directly support the CAARP’s vehicle miles traveled (VMT) reduction goal (Measure M1). By improving transit reliability and accessibility, the CAARP further accelerates the reduction of vehicle trips, which minimizes criteria and ozone precursor air pollutant emissions, directly benefiting the AQMP’s attainment goals. Further, while future physical projects would be implemented to achieve the CAARP’s various strategies, the individual projects requiring discretionary approval would be required to undergo an environmental review pursuant to CEQA in accordance with SCAQMD guidance for evaluating air quality impacts, on a case-by-case basis.

Construction activities that would occur with future CAARP-related projects would comply with applicable CARB requirements, such as those required to minimize short-term emissions from on-road and off-road diesel equipment. Future CAARP-related projects would also be required to comply with applicable SCAQMD regulations for controlling fugitive dust pursuant to SCAQMD Rule 403 (e.g., application of water spray/mists at least three times per day on active areas of disturbance and unpaved roads, limiting truck speed to 15 miles per hour or less on unpaved roads to minimize fugitive dust generation at and around construction sites, etc.). Further, the CAARP includes strategies and measures that would minimize criteria and ozone precursor air pollutant emissions during construction activities that would occur with future CAARP-related projects, such as supporting electrification of off-road equipment (Measure O1), expanding access to public transit for construction workers (Measure M1), and promoting active transportation (Measure M3). These strategies would be consistent with and would not conflict with AQMP control strategies intended to reduce emissions from construction equipment and activities. As the CAARP would not conflict with the control strategies intended to reduce emissions from construction equipment, the CAARP would not conflict with or obstruct implementation of the AQMP, and construction impacts would be less than significant and no mitigation measures would be required.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-11 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 The CAARP includes measures and implementing actions that would result in operational changes in the City to enhance climate resilience that would minimize criteria and ozone precursor air pollutant emissions, including:
• Clean Energy (Measure E1–E4), which would reduce emissions from electricity used by buildings by increasing the percentage of power being supplied by renewable (zero-carbon) electricity and transitioning away from nonrenewable energy sources; • Zero-Emission Vehicles (Measure V1–V3), which supports the shift to zero-emission vehicles (ZEVs);
• Green Buildings and Infrastructure (Measure B1–B4), which reduce the amount of energy buildings consume by improving energy efficiency and promoting all-electric buildings; • Smart Mobility and Active Transportation (Measure M1–M5), which reduce vehicle trips and increasing active transportation modes;
• Off-Road Equipment Electrification (Measure O1), which promote the use of low-emission or electric equipment;
• Recycling and Organic Waste Diversion (Measure R1-R2), which reduce the amount of waste sent to landfills through recycling and diversion programs; and • Water Conservation and Reuse (Measure W1-W2), which reduce emissions associated with the energy needed to treat, transport and deliver water.

In addition, the CAARP focuses on encouraging alternative transportation modes and reducing VMT. These strategies and measures, such as extending transit network coverage (Measure M1), providing end-of-trip bicycle facilities (Measure M3), and expanding bikeway networks (Measure M3) would directly benefit alternative transportation, which would reduce vehicle trips and VMT within the City with a goal of achieving a 5 percent reduction in VMT.

As described in Chapter III, Environmental Checklist, Section XIV, Population and Housing, the CAARP does not propose land use, zoning, or physical changes in the City that would result in new housing or jobs or that would displace existing residents or housing. In addition, the CAARP does not propose new infrastructure, such as roadways or utilities, which would indirectly lead to new population growth or development. Therefore, the CAARP would not conflict with the growth projections identified in the AQMP and would not conflict with or obstruct implementation of the AQMP’s or the City’s strategies and polices intended to reduce air pollutant emissions. Impacts from implementation of the CAARP would be less than significant, and no mitigation measures would be required.
b) Less Than Significant Impact. A significant impact may occur if a project would add a cumulatively considerable contribution of a federal or state non-attainment pollutant. The Air Basin is currently in non-attainment for ozone, particulate matter 10 (PM10), and PM2.5.

As discussed above, the CAARP is a policy document and does not propose the construction or operation of development that would generate criteria pollutant emissions. However, with the adoption and implementation of the CAARP, future CAARP-related projects would have the

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-12 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 potential to generate temporary criteria pollutants from construction activities through the use of heavy-duty construction equipment and vehicle trips. Additionally, there is also a potential for CAARP-related projects to generate fugitive dust emissions resulting from construction activity and operational emissions through vehicle trips energy sources, area sources, such as operation of landscaping equipment and use of consumer products.

The CAARP includes measures and implementing actions that would minimize criteria and ozone precursor air pollutant emissions. Measures A3 and A5 would provide key co-benefits that actively reduce these non-attainment pollutants. Specifically, Measure A3 directly improves air quality by increasing the urban forest, which filters PM10 and PM2.5 and absorbs NOX and VOCs. Similarly, Measure A5 targets improved building systems and includes a focus on enhancing indoor air quality through filtration, which reduces the public’s exposure to both indoor and outdoor pollutants, especially during health-hazardous events like heatwaves or wildfires.

Furthermore, future CAARP-related projects would also be required to comply with applicable SCAQMD regulations for controlling fugitive dust pursuant to SCAQMD Rule 403 (e.g., application of water spray/mists at least three times per day on active areas of disturbance and unpaved roads, limiting truck speed to 15 miles per hour or less on unpaved roads to minimize fugitive dust generation at and around construction sites, etc.). Although the goal of the CAARP is to reduce GHG emissions in the City, adoption and implementation of the CAARP would have co-benefits of reducing air pollutant emissions compared to existing conditions. While future physical improvement projects would be implemented as part of the CAARP’s various strategies, individual projects implemented under the CAARP requiring discretionary approval would be subject to a separate environmental review as required by CEQA, evaluating emissions with respect to the applicable SCAQMD’s regional emissions thresholds, on a case-by-case basis.

Therefore, since the CAARP is a policy document and does not propose specific physical developments, adoption and implementation of the CAARP would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard during construction or operations and impacts would be less than significant, and no mitigation measures would be required. c) Less Than Significant Impact. Certain population groups are especially sensitive to air pollution and should be given special consideration when evaluating potential air quality impacts. As defined in the SCAQMD CEQA Air Quality Handbook, a sensitive receptor to air quality is defined as any of the following land use categories: (1) long-term health care facilities; (2) rehabilitation centers; (3) convalescent centers; (4) retirement homes; (5) residences; (6) schools; (7) parks and playgrounds; (8) child care centers; and (9) athletic fields. Potential impacts from exposure of sensitive receptors to substantial pollutant concentrations is evaluated below.

Construction and Operation
The SCAQMD adopted the Final Localized Significance Thresholds Methodology (2003; revised 2008) for evaluating impacts to sensitive receptors from localized emissions, which utilizes onsite mass emission rate screening levels and project-specific dispersion modeling. The SCAQMD Final Localized Significance Thresholds Methodology establishes screening criteria that can be

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-13 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 used to determine the maximum allowable daily emissions that a project may generate without causing or contributing to an exceedance of the applicable NAAQS without project-specific dispersion modeling. The screening criteria depend on: (1) the area in the South Coast Air Basin in which the project is located, (2) the size of the project area, and (3) the distance between the project’s emission sources and the nearest sensitive receptor. The localized significance thresholds are applicable to NOX, carbon monoxide (CO), PM10, and PM2.5.

As discussed above in Items III.a and III.b, the CAARP is a policy document and does not propose the construction or development that would expose sensitive receptors to substantial pollutant concentrations. Future CAARP-related projects would have the potential to generate localized criteria pollutant emissions. However, CAARP-related projects requiring discretionary approval would be required to undergo an environmental review pursuant to CEQA and in accordance with SCAQMD air quality guidance for the emissions of localized air pollutant thresholds for construction and operations, on a case-by-case basis.

As listed in Item III.a, the CAARP includes measures and implementing actions that would minimize criteria and ozone precursor air pollutant emissions. Future CAARP-related projects would also be required to comply with applicable SCAQMD regulations for controlling fugitive dust pursuant to SCAQMD Rule 403 (e.g., application of water spray/mists at least three times per day on active areas of disturbance and unpaved roads, limiting truck speed to 15 miles per hour or less on unpaved roads to minimize fugitive dust generation at and around construction sites, etc.). Furthermore, implementation of future CAARP-related projects would not include substantial sources of on-site stationary source emissions. Typically, land uses associated with industrial operations, such as chemical processing and warehousing operations with on-site idling trucks have the potential to generate substantial on-site stationary source emissions. Future physical improvement projects that would be implemented with adoption of the CAARP would not be anticipated to include uses that would require stationary sources.

The CAARP’s overall impact on sensitive receptors is net beneficial due to the integration of Adaptation and Resilience strategies, which are designed to actively reduce exposure to climate and pollution hazards. Measure A5 addresses community-identified vulnerabilities regarding air quality and extreme heat. This measure prioritizes improving indoor air quality and thermal safety through enhancements like the installation of air filtration systems in sensitive receptor locations, including residences, schools, and critical public facilities. By upgrading buildings, this measure reduces the exposure of sensitive receptors to outdoor air contaminants that might infiltrate indoor spaces. In addition, Measure A3 would reduce localized outdoor pollutant concentrations and heat exposure in areas used by sensitive receptors by increasing the urban tree canopy, which is known to absorb criteria pollutants and particulate matter. These Adaptation and Resilience measures would work simultaneously with the CAARP’s GHG Reduction measures (Measures V1-V3 and M1-M5) to further reduce pollutants in the City.

Therefore, since the CAARP is a policy document and does not propose specific physical developments, the Project would not result in localized air quality impacts related to construction and operation-related emissions and localized impacts would be less than significant, and no mitigation measures would be required.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-14 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 Carbon Monoxide Hotspot
The potential for projects facilitated by adoption of the CAARP to cause or contribute to CO hotspots is evaluated by comparing project-related traffic volumes on affected roadway intersections (both intersection geometry and traffic volumes) with prior studies conducted by the SCAQMD in support of their AQMPs and considering existing background CO concentrations.

The CAARP is a policy document and does not propose the construction or operation of development that would expose sensitive receptors to CO hotspots. Adoption and implementation of the CAARP would include strategies and measures that would reduce the City’s GHG emissions as well as vehicular CO emissions through strategies such as Zero-Emission Vehicles (Measure V1–V3), which supports the shift to zero-emission vehicles (ZEVs), and Smart Mobility and Active Transportation (Measure M1–M5), which reduces vehicle trips and increasing active transportation modes. Implementation of the CAARP strategies and measures would reduce vehicle trips and VMT within the City with a goal of achieving a 5 percent reduction in VMT. Nonetheless, while CO hotspot impacts are not expected, individual future CAARP-related projects that would occur with adoption of the CAARP requiring discretionary approval would be required to undergo an environmental review pursuant to CEQA, on a caseby-case basis. As a result, impacts related to CO hotspots would be less than significant with implementation of the CAARP, and no mitigation measures would be required.

Toxic Air Contaminants
Construction and operation of future CAARP-related projects may result in emissions of toxic air contaminants (TACs), from diesel particulate matter (DPM) emissions from on- and off-road vehicles during construction. Since the exact nature, location, and operation of the future developments are unknown, and because health risk impacts from TACs are assessed over an extended period of time for proximate sensitive receptors, quantification of potential health risks would be speculative at this time. Implementation of future CAARP-related projects would not include substantial sources of on-site stationary source emissions. Typically, land uses associated with industrial operations, such as chemical processing and warehousing operations with on-site idling trucks have the potential to generate substantial on-site stationary source emissions. Future physical improvement projects that would be implemented with adoption of the CAARP would not be anticipated to include uses that would require stationary sources.

Construction associated with future CAARP-related projects would also be required to comply with CARB and SCAQMD rules and regulations that limit TAC emissions such as the CARB Airborne Toxic Control Measure (ATCM) limiting heavy-duty diesel motor vehicle idling to reduce public exposure to DPM and other TACs (California Code of Regulations Title 13, Section 2485). Nonetheless, these future CAARP-related projects that may occur with adoption of the CAARP would be required to undergo an environmental review pursuant to CEQA and in accordance with applicable SCAQMD guidance for evaluating TAC emissions and associated health risk impacts, on a case-by-case basis. In addition to the regulatory compliance, the CAARP’s long-term implementation of Measure V1 through V3 and the prioritization of sensitive receptor protection through Measure A5 would further reduce the primary source of TAC emissions from mobile sources and the subsequent exposure of sensitive populations to these pollutants.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-15 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 Therefore, as the CAARP is a policy document and does not propose specific physical developments the Project would not result in TAC emissions and impacts related to construction and operation-related TAC emissions would be less than significant, and no mitigation measures would be required.
d) Less Than Significant Impact. According to the SCAQMD CEQA Air Quality Handbook, land uses associated with odor complaints typically include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting, refineries, landfills, dairies, and fiberglass molding. Adoption of the CAARP would not result in the future development of uses identified by SCAQMD as being associated with substantial odors. The CAARP’s waste reduction and diversion strategies (Measure R1-R2) are expected to reduce waste sent to landfills, thereby decreasing the potential for long-term odor generation related to waste decomposition.

As a result, the Project would not discharge other emissions, such as those leading to odors, in quantities that would cause a nuisance, injury, or annoyance to the public or property pursuant to SCAQMD Rule 402. Individual future projects that may be implemented with adoption of the CAARP would also be required to comply with SCAQMD rules that limit operational sources of odors such as Rule 1133 et.seq. that limits odorous emissions from composting and green waste operations and Rules 1113 and 1171 that limit volatile organic compounds (VOC) emissions from architectural coatings and solvents.

Project-specific CAARP-related development may emit odors during temporary construction activities such as from the application of architectural coatings and solvents and the combustion of diesel fuel in on- and off-road equipment. However, these individual future projects would be required to comply with CARB and SCAQMD rules and regulations that limit emissions that would lead to odors such as the CARB anti-idling ATCM (California Code of Regulations Title 13, Section 2485) and SCAQMD Rules 1113 and 1171. Therefore, the Project would not create adverse odors affecting a substantial number of people and impacts would be less than significant, and no mitigation measures are required.

Cumulative Impacts
For purposes of the cumulative air quality analysis with respect to CEQA Guidelines Section 15064(h)(3), the Project’s cumulative air quality impacts are determined not to be significant based on its consistency with the SCAQMD’s adopted 2022 AQMP, as discussed above. With adoption of the CAARP, the Project’s increase in population, housing and employment would not conflict with Connect SoCal 2024 growth projections, upon which the 2022 AQMP is based. Related projects would also be required to assess consistency with the 2022 AQMP transportation control strategies, as well as with population, housing, and employment growth projections in Connect SoCal 2024 and provide mitigation measures if significant impacts are identified. As discussed above, the Project is a policy document and does not itself propose development within the City and would therefore not increase the frequency or severity of an existing violation or cause or contribute to new violations for ozone. Therefore, the Project would be consistent with and would not conflict with or obstruct implementation of the applicable AQMP.

Accordingly, Project air quality impacts are not cumulatively considerable and cumulative impacts are less than significant.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-16 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 The SCAQMD recommends evaluating cumulative impacts for individual projects based on whether the project exceeds the SCAQMD’s recommended daily thresholds for project-specific impacts for those pollutants for which the Air Basin is in non-attainment. Thus, the cumulative analysis of air quality impacts follows SCAQMD’s guidance such that construction or operational Project emissions would be considered cumulatively considerable if Project-specific emissions exceed an applicable SCAQMD recommended significance threshold.

The City relies on thresholds established by the SCAQMD (refer to CEQA Guidelines Section 15064.7) to assess the Project’s cumulative impacts. Regional emissions from a project have the potential to affect the Basin as a whole, and, unlike other environmental issues areas, such as aesthetics or noise, it is not possible to establish a geographical radius from a specific project site where potential cumulative impacts from regional emissions would be limited. Meteorological factors, such as wind, can disperse pollutants, often tens of miles downwind from a project site. Therefore, consistent with accepted and established SCAQMD cumulative impact evaluation methodologies, the potential for the Project to result in cumulative impacts from regional emissions is assessed based on the SCAQMD thresholds.

As described above, the CAARP is a policy document and does not propose the construction or operation of development. The purpose of the CAARP is to reduce the City’s community-wide GHG emissions and to enhance the community’s resilience to the anticipated impacts of climate change. The incorporation of the Adaptation and Resilience measures, such as Measure A3 and A5, ensures that the CAARP provides long-term, structural benefits to air quality and public health. Therefore, cumulative impacts related to health risk, regional, and localized emissions would be less than significant. While future physical projects may be implemented under the CAARP’s various strategies, as well as additional related cumulative projects, individual future projects requiring discretionary approval would be required to undergo an environmental review pursuant to CEQA in accordance with SCAQMD guidance, on a caseby-case basis.

☐ ☐ ☐ ☒
Discussion
a) Less Than Significant Impact. The City is located in an urbanized area with a high-density environment. The City is particularly vulnerable to climate change due to its landscape, which is prone to localized flooding and extreme heat, and its proximity to industrial facilities, pollution sources, and major freeways. Migratory and nesting birds protected by Sections 3503, 3503.5, and 3513 of the California Fish and Game Code (CFGC) and the Migratory Bird Treaty Act (MBTA) may utilize trees, landscaping, and structures throughout the City for nesting habitat.

Special-status species are those plants and animals listed, proposed for listing, or candidates for listing as Threatened or Endangered by the United States Fish and Wildlife Service (USFWS) under the Federal Endangered Species Act (ESA). The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City and would instead promote sustainable infrastructure development and strategies to reduce GHG emissions in the City. The measures proposed in the CAARP would apply to the urbanized areas of the City with low potential for sensitive species or habitat. The CAARP would not have a substantial adverse effect on candidate, threatened, or endangered wildlife species either directly through individual take or indirectly through species habitat modification.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-18 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 Implementation of the CAARP would result in CAARP-related projects which would involve infrastructure development within the urbanized portions of the City and would result in impacts to migratory and nesting birds protected under Sections 3503, 3503.5, and 3513 of the CFGC and under the MBTA through construction activities.

The CAARP measures involve increased energy efficiency and building decarbonization, improving active transportation and public transit facilities, and upgrading water and stormwater facilities. These actions have the potential to disturb nesting habitat for protected birds and raptors. However, the CAARP’s overall effect is beneficial to urban wildlife, particularly birds, through the implementation of Measure A3 which targets a significant increase in the City’s tree canopy, which directly expands the amount of available nesting and foraging habitat for protected birds and raptors, improving the quality and quantity of urban biological resources in the longterm.

Further, construction activities for future CAARP projects would be required to comply with the provisions of the MBTA and CFGC Sections 3503, 3503.5, and 3513 in order to avoid impacts to protected migratory and nesting birds and would be reviewed for consistency with City, state, and federal policies related to protected species on a case-by-case basis. Therefore, the Project would result in a less than significant impact related to special-status wildlife species, and no mitigation measures would be required.
b) No Impact. The City is located in an urbanized area with a high-density urban environment. The City's landscape is identified as being prone to localized flooding, extreme heat, and climate change. There are no riparian habitats within the City.17 The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City and would instead promote sustainable infrastructure development and strategies to reduce GHG emissions in the City.

However, the CAARP includes Measure A4, which would promote the use of bioswales, permeable paving and other green infrastructure and thus improve the quality of stormwater runoff entering the adjacent Los Angeles River. This action is beneficial, as it reduces pollutant loading into the downstream environment, which can indirectly support the ecological health of the regional river system.

Furthermore, the location and details of future CAARP-related projects would be reviewed for consistency with relevant regulations prior to approval on a case-by-case basis. Therefore, the Project would not have a substantial adverse effect on riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the CDFW and USFWS, thus no impact would occur, and no mitigation measures would be required. c) Less Than Significant Impact. According to the USFWS National Wetlands Inventory, the City is immediately adjacent to the Los Angeles River, which consist of 149.59 and 236.92 acres of 17 USFW. 2025.

City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-19 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 riverine habitat, classified as a Riverine (R) Lower Perennial (2) Unconsolidated Shore (US), Seasonally Flooded (C), Artificial Substrate (r) (R2USCr).18,19 The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City and would instead promote sustainable infrastructure development and strategies to reduce GHG emissions in the City. The incorporation of Measure A4 would be beneficial to the adjacent protected riverine habitat/wetland area. By prioritizing infiltration and filtering of stormwater runoff before it enters the Los Angeles River, Measure A4 would reduce pollutant transport and improve hydrological quality, thus minimizing indirect adverse effects on the federally protected wetlands.

As mentioned above, the location and details of future CAARP-related projects would be reviewed for consistency with relevant regulations prior to approval on a case-by-case basis.

Therefore, the Project would not have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (CWA) through direct removal, filling, hydrological interruption, or other means, and impacts would be less than significant, and no mitigation measures would be required.
d) No Impact. As mentioned above, the City is located in an urbanized area with a high-density urban environment. The CAARP is a policy document focused on reducing GHG emissions in the City and creating measures to address climate change impacts in the community. The CAARP does not propose land use, zoning, or physical changes in the City that would impede the movement of any native resident or migratory fish or wildlife species. However, the CAARP measures involve increased energy efficiency and building decarbonization, improving active transportation and public transit facilities, and upgrading water and stormwater facilities. These actions have the potential to disturb nesting birds and migratory species. In addition, the CAARP’s long-term effect is beneficial to these species, as Measure A3 is designed to increase the density and quality of urban habitat, thus expanding nesting sites and urban wildlife corridors within the City.

Furthermore, construction activities for future CAARP projects would be required to comply with the provisions of the MBTA and CFGC Sections 3503, 3503.5, and 3513 in order to avoid impacts to protected migratory and nesting birds and would be reviewed for consistency with City, state, and federal policies related to protected species on a case-by-case basis. As such, the CAARP would not have a substantial adverse effect on nesting and migratory birds. Therefore, the Project would not interfere with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites, thus no impact would occur, and no mitigation measures would be required.

City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-20 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 e) Less Than Significant Impact. The City’s General Plan Open Space and Conservation Elements incorporate policies to protect biological resources such as plants, trees, wildlife habitats, and the species that utilize these habitats. 20,21 The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City and would instead promote sustainable infrastructure development and strategies to reduce GHG emissions in the City. The purpose and intended effect of the CAARP is to reduce GHG emissions generated in the City to help reduce the effects of climate change. Implementation of the Project strategies would align with the General Plan Open Space and Conservation Elements and would be beneficial by helping the City meet applicable local policies and ordinances for protecting biological resources and reducing GHG emissions simultaneously. In addition, implementation of Measure A3 would directly implement the General Plan’s goals for protecting and increasing the City’s urban forest, which is the primary biological resource within the City. Thus, the Project would not conflict with or obstruct implementation of the applicable policies for preserving biological resources and would not affect the City’s ability to attain goals and policies that protect biological resources.

Therefore, the Project would not conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance and impacts would be less than significant, and no mitigation measures would be required. f) No Impact. The purpose and intended effect of the CAARP is to reduce GHG emissions generated and help reduce the effects of climate change within the City. The CAARP does not propose land use, zoning, or physical changes in the City. In addition, the City is not located within a conservation plan.22 Therefore, the Project would not include any physical change that would conflict with an adopted Habitat Conservation Plan (HCP), Natural Community Conservation Plan (NCCP), or other approved local, regional, or state habitat conservation plant thus no impact would occur, and no mitigation measures would be required.

b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to §15064.5? ☐ ☒ ☐ ☐ c) Disturb any human remains, including those interred
outside of dedicated cemeteries? ☐ ☒ ☐ ☐
Discussion
CEQA defines historic resources as those that are listed on, or determined to be eligible for listing on, the California Register of Historical Resources (CRHR) or a local register, or are otherwise determined to be historical pursuant to CEQA (PRC Section 21084.1) or CEQA Guidelines (CCR Title 14, Section 15064.5). The CRHR also includes properties formally determined eligible or listed in the National Register of Historic Places (PRC Section 5024.1). A historic resource may be an object, building, structure, site, area, place, record, or manuscript that is historically significant or significant in terms of California’s architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural records (PRC Section 5020.1(j)). Typically, historic resources are more than 50 years old.

Archaeological resources may be considered historic resources or, if not, they may be determined to be “unique” as defined by CEQA (PRC Section 21083.2(g)). A “unique archaeological resource” is an archaeological artifact, object, or site about which it can be clearly demonstrated that, without merely adding to the current body of knowledge, there is a high probability that it meets any of the following criteria: (1) contains information needed to answer important scientific research questions and that there is a demonstrable public interest in that information; (2) has a special and particular quality such as being the oldest of its type or the best available example of its type; or (3) is directly associated with a scientifically recognized important prehistoric or historic event or person.

When an initial study identifies the existence of, or the probable likelihood, of Native American human remains within the project, a lead agency shall work with the appropriate Native Americans as identified by the Native American Heritage Commission as provided in Public Resources Code section 5097.98.

The applicant may develop an agreement 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 Native American Heritage Commission." a) Less Than Significant Impact with Mitigation Incorporated.

City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-23 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 could, depending on their location, result in direct or indirect adverse changes to the significance of historical resources. For example, such changes could result from construction of natural gas equipment and appliances at City buildings and facilities, installment of publicly accessible charging infrastructure (electrical vehicles), freeway improvements, expansion of public transit, and dense residential construction. These activities have the potential to cause significant and unavoidable impacts on historical resources. However, future projects would be required to comply with existing federal, State, and local regulations that protect historical resources and undergo the City’s discretionary review process, where applicable, including completion of subsequent project-level planning and environmental review under CEQA. Implementation of Mitigation Measure CR-1 would further reduce impacts by requiring projects with the potential to impact historic or archaeological resources to undergo expert evaluation, documentation, and impact analysis by qualified professionals. Refer to Appendix D, Mitigation Monitoring and Reporting Program, of this ISMND. Therefore, the Project would result in a less than significant impact with mitigation incorporated.

Refer to Appendix D, Mitigation Monitoring and Reporting Program, of this ISMND. Therefore, the Project would result in a less than significant impact with mitigation incorporated.

Mitigation Measures
Mitigation Measure CR-1: Future Study – Historical and Unique Archaeological Resources.

New projects under the plan that could have a potential direct or indirect impact to historic and archaeological resources and are within or adjacent to (within 100 feet of) structures that are more than 45 years old, or have been recorded as historic resources or that require ground disturbance that could impact archaeological resources that might be found to be significant historical resources under CEQA.

The City shall retain a qualified architectural historian, defined as meeting the Secretary of the Interior’s Professional Qualification Standards for architectural history and a Qualified Archaeologist under the Secretary of the Interior Standards. The architectural historian will conduct a historic resources assessment including: a records search, at the South Central Coastal Information Center (SCCIC); a review of pertinent archives and sources; a pedestrian field survey; updates or full recordation of all identified historic resources on California Department of Parks and Recreation 523 forms; and preparation of a technical memo documenting the methods and results of the assessment. All identified historic resources shall be assessed for the project’s potential to result in direct and/or indirect effects to those resources and any historic resource that may be affected shall be evaluated for its potential significance (i.e., listing in the CRHR) prior to the City’s approval of project plans and publication of subsequent CEQA documents. The qualified architectural historian shall provide recommendations regarding avoidance or minimizing impacts, or treatment for historical resources (i.e., resources found eligible for listing in the CRHR) that will be affected by the project.

The qualified archaeologist shall review the SCCIC record search, historic maps, soil maps, and aerial photographs along with any other relevant information to determine land use history and archaeological sensitivity. Areas of medium to high sensitivity will be assessed for the project’s potential to result in direct effects to those resources and any archaeological resource that may be affected shall be evaluated for its potential significance (i.e., listing in the CRHR) prior to the City’s approval of project plans and publication of subsequent CEQA documents. The qualified archaeologist shall provide recommendations regarding avoidance or minimizing impacts, or treatment for historical resources or unique archaeological resources (i.e., resources found eligible for listing in the CRHR) that will be affected by the project.

Mitigation Measure CR-2: Inadvertent Discovery of Human Remains. If human skeletal remains are uncovered during ground disturbance the City shall immediately halt work, contact the Los Angeles County coroner to determine whether the remains are human, and follow the procedures and protocols set forth in Section 15064.5 (e)(1) of the CEQA Guidelines. If the County Coroner determines that the remains are Native American, they shall contact the Native American Heritage Commission (NAHC), in accordance with Health and Safety Code Section 7050.5, subdivision (c), and Public Resources Code Section (PRC) 5097.98 (as amended by AB 2641). The NAHC shall then identify the person(s) thought to be the Most Likely Descendant

Per PRC 5097.98, the landowner shall ensure that the immediate vicinity, according to generally accepted cultural or archaeological standards or practices, where the Native American human remains are located, is not damaged or disturbed by further development activity until the landowner has discussed and conferred, as prescribed in this section (PRC 5097.98), with the MLD regarding their recommendations, if applicable, taking into account the possibility of multiple human remains.

Significance Determination
Less Than Significant Impact with Mitigation Incorporated Cumulative Impacts
The CAARP is a policy document that guides future development in the City toward GHG reduction and climate adaptation, and it does not authorize any specific physical construction that would cause a direct significant impact to cultural resources. However, when viewed cumulatively with other foreseeable developments in the City, the CAARP-related projects would involve ground disturbance and structural modifications that could potentially impact cultural resources. This cumulative scenario is due to the fact that all future CAARP-related projects must adhere to federal, state, and local regulations, as well as mitigation measure CR-1. Therefore, because the CAARP itself is consistent with all required projectlevel compliance with federal, state, and local laws, the Project’s incremental contribution to cumulative impacts on historical resources is not cumulatively considerable, resulting in a less than cumulatively considerable impact.

Regarding subsurface resources, including archaeological resources and human remains, the cumulative impact of future City development could be cumulatively considerable given the unknown location of future CAARP-related projects. However, the CARRP would adhere to all federal, state, and local laws as well as mitigation measures CR-1 and CR-2. Therefore, because the CAARP itself is consistent with all required project-level compliance with federal, state, and local laws, the Project’s incremental contribution to cumulative impacts on archeological resources and human remains is not cumulatively considerable, resulting in a less than cumulatively considerable impact.

VI. ENERGY — Would the project:
a) Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary consumption of energy resources, during project construction or
operation?
☐ ☐ ☒ ☐
b) Conflict with or obstruct a state or local plan for
renewable energy or energy efficiency? ☐ ☐ ☒ ☐
Discussion
a) Less Than Significant Impact. The CAARP is a policy document and does not propose the construction or operation of development that would directly consume energy resources, such as electricity, natural gas, and transportation fuels. The purpose of the CAARP is to reduce the City’s community-wide GHG emissions and to enhance the community’s resilience to the anticipated impacts of climate change. While future CAARP-related projects would be implemented under CAARP’s various strategies, the individual projects requiring discretionary approval would be required to undergo an environmental review pursuant to CEQA, on a caseby-case basis.

Although adoption and implementation of the CAARP would not directly result in the consumption of energy resources through construction or operational activities or development, the CAARP includes strategies and measures that would reduce energy consumption in future project-specific CAARP-related projects. These strategies and measures include the following:
• Clean Energy (Measure E1–E4), which reduce emissions from electricity used by buildings by increasing the percentage of power being supplied by renewable (zero-carbon) electricity and transitioning away from nonrenewable energy sources; • Zero-Emission Vehicles (Measure V1–V3), which supports the shift to zero-emission vehicles (ZEVs);
• Green Buildings and Infrastructure (Measure B1–B4), which reduce the amount of energy buildings consume by improving energy efficiency and promoting all-electric buildings; • Smart Mobility and Active Transportation (Measure M1–M5), which reduce vehicle trips and increasing active transportation modes;
• Off-Road Equipment Electrification (Measure O1), which promote the use of low-emission or electric equipment;
• Recycling and Organic Waste Diversion (Measure R1-R2), which reduce the amount of waste sent to landfills through recycling and diversion programs; and • Water Conservation and Reuse (Measure W1-W2), which reduce emissions associated with the energy needed to treat, transport and deliver water.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-27 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 In addition to these GHG reduction strategies, the CAARP’s Adaptation and Resilience measures directly and proactively reduce energy demand, particularly during high-stress conditions like extreme heat. Measure A3 directly reducing the urban heat island effect and solar heat gain on buildings. By increasing shade and tree canopy, the demand for high-energy consuming mechanical air conditioning in adjacent buildings is decreased, resulting in a permanent reduction in energy consumption for cooling. Similarly, Measure A5 focuses on improving building energy performance and thermal safety, specifically through retrofits that increase insulation and efficiency. By reducing the thermal load on buildings, Measure A5 ensures that new or existing cooling equipment operates more efficiently, further lowering net energy consumption.

The CAARP focuses on encouraging alternative transportation modes and reducing VMT. These strategies and measures, such as extending transit network coverage (Measure M1), providing end-of-trip bicycle facilities (Measure M3), and expanding bikeway networks (Measure M3) would directly benefit alternative transportation, which would reduce vehicle trips and VMT within the City with a goal of achieving a 5 percent reduction in VMT. The reduction in vehicle trips and VMT within the City would reduce demand on transportation fuels from those who travel within the City. Therefore, based on the strategies in the CAARP that would reduce energy consumption, including transportation fuels, and the inclusion of Measures A3 and A5 that reduce energy demand, impacts due to wasteful, inefficient, or unnecessary consumption of energy resources would be less than significant, and no mitigation measures are required. b) Less Than Significant Impact. The CAARP is a policy document and does not propose the construction or operation of development that would conflict with or obstruct a state or local plans for renewable energy or energy efficiency. While future physical projects may be implemented under CAARP’s various strategies, the individual projects requiring discretionary approval would be required to undergo an environmental review pursuant to CEQA, on a caseby-case basis. Future CAARP-related projects would be required to comply with applicable federal, state, and local regulations pertaining to energy consumption, including utilization of vehicles that comply with the Pavley Regulation (AB 1493), Advanced Clean Cars (ACC), and the California Mobile Source Strategy; utilization of electric utility providers that comply with the Renewables Portfolio Standard (RPS) and Clean Energy and Pollution Reduction Act (SB 350); building designs that comply with the California Code of Regulations Title 24 (California Building Standards Code), and other applicable regulations administered through the USEPA, National Highway Traffic Safety Administration (NHSTA), and the CARB regarding building energy and transportation fuel efficiency.

Adoption of the CAARP would also support federal, state, and local energy goals through the implementation of strategies and measures that reduce energy consumption and promote the adoption of renewable energy resources beyond regulatory requirements. These strategies and measures include those previously listed above in Item VI.a. The CAARP’s Adaptation and Resilience measures are also in alignment with and advance state and local energy efficiency goals. Specifically, Measure A5 supports the core objective of Title 24 and other state efficiency programs by targeting energy-saving retrofits and building improvements, ensuring that energy is conserved. In addition, Measure A3 provides a natural, passive cooling mechanism that

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-28 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 complements state and local efforts to reduce peak electricity demand and avoid stressing the grid during extreme heat events.

In summary, these strategies and measures would reduce energy and transportation fuel consumption through targeted improvements across multiple sectors. Building energy efficiency would be enhanced by transitioning to renewable electricity sources and implementing allelectric, high-efficiency building designs. Water energy efficiency would improve through conservation and reuse initiatives that lower the energy required for water treatment and distribution. Solid waste reduction would be achieved by diverting organic and recyclable materials from landfills, thereby decreasing energy use and emissions associated with waste processing. Transportation fuel demand would decline through the promotion of zero-emission vehicles, electrification of off-road equipment, and expanded support for smart mobility and active transportation, all of which reduce reliance on fossil fuels and vehicle trips. As such, the CAARP would support plans for reducing the consumption of energy sources such as electricity, natural gas, and transportation fuels within the City, deploying renewable and zero emissions technologies, and improving energy efficiency. Therefore, the Project would not conflict with or obstruct a state or local plan for renewable energy or energy efficiency, and impacts would be less than significant, and no mitigation measures are required.

Cumulative Impacts
Cumulative impacts occur when the incremental effects of a Project are significant when combined with similar impacts from other past, present, or reasonably foreseeable projects in a similar geographic area.

The geographic context for the analysis of cumulative impacts on electricity is Southern California Edison’s (SCE) service area, and the geographic context for the analysis of cumulative impacts on natural gas is Southern California Gas Company (SoCalGas) service area. While the geographic context for transportation-related energy use is more difficult to define, the Project is considered in the context of Los Angeles County-wide consumption given the tendency for vehicles to travel within and through the Los Angeles County and the availability of Los Angeles County-level data. Growth within these geographies is anticipated to increase the demand for electricity, natural gas, and transportation energy, as well as the need for energy infrastructure, such as new or expanded energy facilities.

As mentioned above, the CAARP is a policy document and does not propose the construction or operation of development. The purpose of the CAARP is to reduce the City’s community-wide GHG emissions and to enhance the community’s resilience to the anticipated impacts of climate change. The CAARP includes strategies and measures that reduce the consumption of energy sources such as electricity, natural gas, and transportation fuels within the City. The incorporation of Measures A3 and A5 ensures that the CAARP’s beneficial impacts regarding energy are reduced. Therefore, cumulative energy impacts would not result in the inefficient use of energy consumption nor conflict with any state or local plan for renewable energy or energy efficiency. Cumulative impacts would be less than significant, and no mitigation measures are required.

Discussion
a.i) No Impact. The City is in a seismically active region, with several active and potentially active faults capable of affecting the City, including the San Andreas, Newport-Inglewood, San Fernando, Sierra Madre, and Whittier faults.23 Potentially active faults in the immediate vicinity of the City include the Norwalk, Raymond Hill, Malibu Coast-Santa Monica-Hollywood, and Verdugo.24 Although the City is located in a seismically active region, there are no Alquist-Priolo Earthquake Fault Zones within the City.25 The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City that would increase seismic risk.

Therefore, the Project would not directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving a rupture of a known earthquake fault, as 23 City of Maywood, 2023. 2023 Safety Element. Available at:

The CAARP proposed measures focus on transportation, electricity, natural gas, solid waste, wastewater treatment, and energy use for water conveyance. The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City and instead proposes measures focused on reducing GHG emissions in the City. Any individual construction projects that would result from the adoption of the CAARP, such as installing EV charging stations (Measure V1) would be required to adhere to seismic standards of the California Building Code (CBC), which are designed to avoid safety and property risk associated with ground shaking. Furthermore, Measure A5 prioritizes the upgrade and protection of critical facilities and infrastructure following a seismic event to ensure that they withstand strong ground shaking and remain operational. Therefore, the Project would not directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving strong seismic ground shaking, and no impact would occur.
a.iii) Less Than Significant Impact. Liquefaction susceptibility is influenced by the physical properties of soil, such as grain-size distribution, compaction, cementation, saturation, and depth.

In the City, the underlying geologic materials are firm and dense, with a substantial proportion of clay.26 The potential for liquefaction is considered to be very low for most of the City north of Slauson Avenue.
27 However, ground water levels and soil characteristics increase the liquefaction potential for the portion of the City south of Slauson Avenue, with a small area in the extreme southeast corner of the City having a high liquefaction potential.28 According to the California Geologic Survey (CGS), the City is located within a Liquefaction Zone.29 The Safety Element of the City’s General Plan suggest that further investigation may be required to understand the degree and extent of the liquefaction risk in the City. The CAARP’s incorporation of Measure A5 would be beneficial, as it ensures that the critical facilities most essential for public safety and recovery are prioritized against seismic hazards, including liquefaction risk, thereby reducing the impacts during such events. Any future CAARP-related project would be required to adhere to the seismic standards of the CBC, which are designed to avoid safety and property risk associated with ground shaking. Therefore, the Project would not directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving liquefaction and impacts would be less than significant, and no mitigation measures would be required a.iv) No Impact. The geologic and topographic characteristics of an area often determine its potential for landslides. Landslides (or slope failure) refer to the dislodging and failing of a mass of soil or rocks along a sloped surface.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-31 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 City is not located in the path of any potential landslides.30 Therefore, the Project would not directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death involving landslides thus no impact would occur, and no mitigation measures would be required.
b) No Impact. As mentioned above, the CAARP is a policy document and does not propose land use, zoning, or physical changes in the City and would instead promote sustainable infrastructure development and strategies to reduce GHG emissions in the City. The CAARP proposed measures that would involve minor ground disturbance, such as installing bioswales along streets (Measure W2), promoting transit oriented development (Measure M2), or improving street design (Measure M3), would be subject to existing City regulations to prevent erosion and would occur on previously disturbed urban land. Any future CAARP-related project would be required to comply with the CBC and would also be subject to a separate environmental review under CEQA. The CAARP would not involve construction that would result in the loss of topsoil; thus, no impact would occur, and no mitigation measures would be required. c) Less Than Significant Impact. Unstable geologic units or soils commonly occur when there are landslides, lateral spreading, subsidence/collapse, or liquefaction.

Landslides
The geologic and topographic characteristics of an area often determine its potential for landslides. Landslides (or slope failure) refer to the dislodging and falling of a mass of soil or rocks along a sloped surface. Since the CAARP is a policy document and does not propose physical changes to the environment and given the City’s flat topography, the potential for geologic hazards such as landslides are considered low. Therefore, the Project would not be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the Project, and potentially result in on- or off-site landslide, thus no impact would occur, and no mitigation measures would be required.

Lateral Spreading
Lateral spreading movement occurs when a soil mass slides laterally on liquefied soil layers, moving downslope or towards a free face. As mentioned above, the City is located within a liquefaction hazard zone and therefore, there is potential for lateral spreading to occur within the City.31 However, since the CAARP is a policy document and does not propose land use, zoning, or physical changes in the City and would instead promote sustainable infrastructure development and strategies to reduce GHG emissions in the City, the Project would not result in a potentially significant impact and would not expose people or structures to substantial adverse effects associated with lateral spreading such as liquefaction, thus impacts would be less than significant, and no mitigation measures would be required.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-32 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 Subsidence/Collapse
The City is located in the Los Angeles basin, an alluvial lowland underlain by a structural depression that has experienced periodic and continuous subsidence over millions of years.32 The natural topography of the City is level, with local relief ranging from 140 to 175 feet above sea level. The City is in a seismically active region, with several active and potentially active faults capable of affecting the City, including the San Andreas, Newport-Inglewood, San Fernando, Sierra Madre, and Whittier faults. The City is located on relatively flat-lying ground that has no slope stability problems for lurching, and no large-scale extraction of groundwater, gas, oil, or geothermal energy is occurring or planned within the City or in the general site vicinity.33 As such, the potential for ground subsidence due to withdrawal of fluids or gasses within the City is considered low. Therefore, the Project would not result in a significant impact and would not expose people or structures to substantial adverse effects associated with subsidence or collapse thus no impact would occur, and no mitigation measures would be required.

Liquefaction
As discussed above, the City is located within a liquefaction zone.34 As stated in the Safety Element of the City’s General Plan, it is suggested that further investigation may be required to understand the degree and extent of the liquefaction risk in the City. Any future CAARP-related project would be required to adhere to the seismic standards of the CBC, which are designed to avoid safety and property risk associated with ground shaking. As noted above, the incorporation of Measure A5 further mitigates the consequences of these seismic-related ground failures by ensuring that facilities essential to community safety are protected against these risks. Therefore, the Project would not result in a potentially significant impact and would not expose people or structures to substantial adverse effects associated with liquefaction thus impacts would be less than significant, and no mitigation measures would be required. d) Less Than Significant Impact. As discussed above, the CAARP is a policy document and does not propose land use, zoning, or physical changes in the City and would instead promote sustainable infrastructure development and strategies to reduce GHG emissions in the City. Any future CAARP-related project would be required to adhere to seismic standards of the CBC, which is designed to avoid hazards related to soil constraints and geologic conditions. Therefore, the Project would not be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code35, creating substantial direct or indirect risks to life or property, thus impacts would be less than significant, and no mitigation measures would be required. e) No Impact. The CAARP would outline a strategic roadmap with clear goals, innovative strategies, and actionable measures across various sectors. These include transportation, electricity, natural gas, solid waste, wastewater treatment, and energy use for water conveyance. 32 City of Maywood, 2023. 2023 Safety Element. Available at:

City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-33 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 However, the CAARP is a policy document and does not propose land use, zoning, or physical changes in the City. Therefore, the Project would not involve the use of septic tanks of alternative wastewater disposal systems thus no impact would occur, and no mitigation measures would be required.
f) Less Than Significant Impact with Mitigation Incorporated. The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City and would instead promote sustainable infrastructure development and strategies to reduce GHG emissions in the City. As a policy document, the CAARP itself would not result in direct impacts to paleontological resources. However, future projects implementing GHG reduction measures that would involve ground disturbing activities could have the potential to damage or destroy a unique paleontological resource or site or unique geologic feature. Implementation of Mitigation Measure PR-1 would further reduce impacts by requiring projects with the potential to impact paleontological resources to undergo expert evaluation, documentation, and impact analysis by qualified professionals. Refer to Appendix D, Mitigation Monitoring and Reporting Program, of this ISMND. Therefore, the Project would result in a less than significant impact with mitigation incorporated
Mitigation Measures
Mitigation Measure PR-1: Future Study – Paleontological Resources. New projects under the plan that could have a potential direct impact to paleontological resources and are within sensitive geological formations, and that require ground disturbance that could impact paleontological resources.

The City shall retain a qualified paleontologist under the specifications of the Society of Vertebrate Paleontology (SVP). The paleontologist will request a records search from the Los Angeles County Museum of Natural History; conduct a review of pertinent geological maps and literature; and prepare a technical memo documenting the methods and results of the assessment.

All identified sensitive formations shall be assessed for the project’s potential to result in direct effects to those resources prior to the City’s approval of project plans and publication of subsequent CEQA documents. The qualified paleontologist shall provide recommendations regarding avoidance or minimizing impacts, or treatment for significant paleontological resources.

greenhouse gases?
☐ ☐ ☒ ☐
Discussion
a) Less Than Significant Impact. State regulated GHGs include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3). CO2 is the most abundant GHG in the atmosphere. Emissions of CO2, CH4, and N2O are of principal concern for development projects as they are associated with the combustion of fossil fuels such as diesel, gasoline, and natural gas.

Emissions of CH4 are also associated with wastewater treatment and solid waste decomposition.

Impacts of GHGs are borne globally, as opposed to localized air quality effects of air pollutants and toxic air contaminants. The quantity of GHGs that it takes to result in climate change is not precisely known; however, it is clear that the quantity is enormous, and no single project would measurably contribute to a noticeable incremental change in the global average temperature, or to global, local, or micro climates. From the standpoint of CEQA, GHG impacts to global climate change are inherently cumulative.

The City’s CAARP, is a policy document designed to reduce GHG emissions and enhance community resilience to climate change. Chapter 3 of the CAARP identifies two GHG emissions reduction targets – a near-term target for 2035 and a long-term target for 2045 – that align with state and regional targets. These targets represent emissions levels that the City can achieve, based on quantitative emissions modeling, through the implementation of the CAARP’s strategies, measures, and actions. The CAARP does not propose land use changes, zoning changes, or any specific physical development. Future individual projects requiring discretionary approval would be required to undergo an environmental review pursuant to CEQA in accordance with SCAQMD guidance, on a case-by-case basis. The adoption and implementation of the CAARP would not result in the construction or operation of physical development, GHG emissions are not quantified and are qualitatively discussed.

Although approval of the Project would not result in the direct construction of physical development, the CAARP includes strategies and measures that would minimize GHG emissions during construction of future CAARP-related projects, such as supporting electrification of offroad equipment (Measure O1), expanding access to public transit (Measure M1), and promoting active transportation (Measure M3). Additionally, Future CAARP-related projects construction are required to comply with applicable federal, state, and local rules and regulations pertaining to the minimizing GHG emissions.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-36 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 Adoption of the CAARP would establish strategies and measures that would reduce, either directly or indirectly, operational community-wide GHG emissions in the City, including the following:
• Clean Energy (Measure E1–E4), which reduce emissions from electricity used by buildings by increasing the percentage of power being supplied by renewable (zero-carbon) electricity and transitioning away from nonrenewable energy sources; • Zero-Emission Vehicles (Measure V1–V3), which supports the shift to zero-emission vehicles (ZEVs);
• Green Buildings and Infrastructure (Measure B1–B4), which reduce the amount of energy buildings consume by improving energy efficiency and promoting all-electric buildings; • Smart Mobility and Active Transportation (Measure M1–M5), reducing vehicle trips and increasing active transportation modes;
• Off-Road Equipment Electrification (Measure O1), which promote the use of low-emission or electric equipment;
• Recycling and Organic Waste Diversion (Measure R1-R2), which reduce the amount of waste sent to landfills through recycling and diversion programs; and • Water Conservation and Reuse (Measure W1-W2), which reduce emissions associated with the energy needed to treat, transport and deliver water.

The CAARP also incorporates climate Measures A3, A4, and A5, that provide co-benefits by reducing energy demand and associated GHG emissions. Measure A3 provides permanent passive cooling to the built environment, which directly reduces electricity consumption for air conditioning. Measure A4 increases local water infiltration and reduces the volume of stormwater requiring distant conveyance and treatment, thereby reducing the energy-related emissions associated with water management. Lastly, Measure A5 improves building envelopes and thermal performance, which supports the Green Buildings and Infrastructure strategy by reducing heating, cooling needs, and increasing energy efficiency.

City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-37 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 b) Less Than Significant Impact. Adoption and implementation of the CAARP would not conflict with an applicable plan, policy or regulation adopted for the purpose of reducing GHG emissions.

A consistency analysis is provided below and describes the Project’s general conformance with the applicable strategies and measures in the CARB 2022 Scoping Plan and Connect SoCal 2024 RTP/SCS.
2022 Climate Change Scoping Plan
The CARB 2022 Scoping Plan was approved in December 2022 and expands on prior scoping plans and recent legislation, such as AB 1279, by outlining a technologically feasible, costeffective, and equity-focused path to achieve the state’s climate target of reducing anthropogenic GHG emissions to 85 percent below 1990 levels and achieving carbon neutrality by 2045 or sooner. AB 1279, The California Climate Crisis Act, establishes that the State would be required to achieve net zero GHG emissions as soon as possible but no later than 2045, and to achieve and maintain net negative GHG emissions thereafter.

Table 8, Project Compliance with Applicable 2022 Scoping Plan Actions and Strategies, contains a list of GHG-reducing strategies as they relate to the Project. The analysis describes the consistency of the Project with these strategies that support the State’s strategies in the 2022 Scoping Plan to reduce GHG emissions. The 2022 Scoping Plan relies on a broad array of GHG reduction actions, which include direct regulations, alternative compliance mechanisms, incentives, voluntary actions, and market-based mechanisms such as the Cap-and-Trade program.

The Project would not conflict with applicable 2022 Scoping Plan actions and strategies to reduce GHG emissions.

Consistent. Adoption of the CAARP would establish strategies and measures that would increase renewable energy and decrease reliance on oil and gas resources by transitioning to zero emissions technologies, whereas the purpose of the CAARP is to reduce the City’s community-wide GHG emissions and to enhance the community’s resilience to the anticipated impacts of climate change. The CAARP incorporates strategies and measures that would be consistent with this action, including the following: Clean Energy (Measure E1–E4), which reduce emissions from electricity used by buildings by increasing the percentage of power being supplied by renewable (zero-carbon) electricity and transitioning away from nonrenewable energy sources; Zero-Emission Vehicles (Measure V1–V3), which supports the shift to zero-emission vehicles (ZEVs); Green Buildings and Infrastructure (Measure B1–B4), which reduce the amount of energy buildings consume by improving energy efficiency and promoting all-electric buildings; Smart Mobility and Active Transportation (Measure M1–M5), reducing vehicle trips and increasing active transportation modes; and OffRoad Equipment Electrification (Measure O1), which promote the use of low-emission or electric equipment. The above strategies and measures would also align with and support SCE’s compliance with the State RPS and electricity-related GHG emissions would decline in successive years as grid-generated electricity is generated from increased percentages of renewable energy sources. Therefore, the Project would not conflict with this action.

Adoption of the CAARP would establish strategies and measures that would increase transportation fuel efficiency through zero emission technologies or low-emission equipment, as well as reduce VMT in the City with a goal of a 5 percent reduction. The CAARP incorporates strategies and measures that would be consistent with this action, including the following: Zero-Emission Vehicles (Measure V1–V3), which supports the shift to zero-emission vehicles (ZEVs); Smart Mobility and Active Transportation Strategy (Measure M1–M5), reducing vehicle trips and increasing active transportation modes; and Off-Road Equipment Electrification (Measure O1), which promote the use of low-emission or electric equipment. Thus, the Project would not conflict with the State’s ability to implement the low carbon fuel standard.

Expansion of Electrical Infrastructure
Actions
Consistent. Adoption of the CAARP would establish strategies and measures that would support the decarbonization of the electricity sector by encouraging the replacement of fossil fuel-derived electricity with renewable and zero emission technologies. The CAARP incorporates strategies and measures that would be consistent with this action, including the following: Clean Energy (Measure E1–E4), which reduce emissions from electricity used by buildings by increasing the percentage of power being supplied by renewable (zero-carbon) electricity and transitioning away from nonrenewable energy sources; and Green Buildings and Infrastructure (Measure B1–B4), which reduce the amount of energy buildings consume by improving energy efficiency and promoting all-electric buildings. The above strategies and measures would also align with and support SCE’s compliance with the State RPS and electricity-related GHG emissions would decline in successive years as grid-generated electricity is generated from increased percentages of renewable energy sources. Therefore, the Project would not conflict with this action.

Climate Ready and Climate-Friendly
Buildings
Consistent. Adoption and implementation of the CAARP would align building standards in the City to support zero-emission new construction and develop building performance standards for existing buildings. The CAARP incorporates strategies and measures that would be consistent with this action, including the following: Clean Energy (Measure E1–E4), which reduce emissions from electricity used by buildings by increasing the percentage of power being supplied by renewable (zero-carbon) electricity and transitioning away from nonrenewable energy sources; Zero-Emission Vehicles (Measure V1), which supports the shift to zero-emission vehicles (ZEVs); and Green Buildings and Infrastructure (Measure B1–B4), which reduce the amount of energy buildings consume by improving energy efficiency and promoting all-electric buildings. These strategies and measures would enable new construction and existing buildings to maximize energy efficiency and support climate-friendly infrastructure.

Therefore, the Project would not conflict with this action.

Expanded Use of Zero-Emission
Mobile Source Technology Actions
Consistent. Adoption of the CAARP would expand the use of zero-emission mobile source technology within the City.

Local Jurisdictions Consistent. Adoption of the CAARP would not conflict with this strategy. The CAARP would enhance the community’s resilience to the anticipated impacts of climate change. The CAARP incorporates strategies and measures that would be consistent with this action, including Smart Mobility and Active Transportation (Measure M1– M5), reducing vehicle trips and increasing active transportation modes. The Project would not offer any jobs or educational resources. The Project would aid in the accessibility to nearby jobs our resources associated with the potential employment locations surrounding the Project Area.

Advance a resilient and efficient
goods movement system that
supports the economic vitality of the
region, attainment of clean air and
quality of life for our communities.

Local Jurisdictions Consistent. Adoption of the CAARP would not conflict with this strategy. The Project includes strategies and measures aimed at accelerating freight decarbonization (Measure V3), which would directly impact goods movement, specifically supporting the attainment of clean air and quality of life for communities. Therefore, the Project would not conflict with the goods movements strategies in Connect SoCal 2024.

Source: ESA, 2025; SCAG’s 2024-2050 Regional Transportation Plan/Sustainable Communities Strategy, 2024 As discussed in Table 9, the Project would not conflict with SCAG’s Connect SoCal 2024 and would be supportive of the actions and strategies contained therein. Therefore, GHG impacts would be less than significant with respect to the Connect SoCal 2024.

Overall, the Project would not conflict with an applicable plan, policy, or regulation to reduce GHG emissions as the CAARP would be consistent with applicable plans, policies and regulations and implementation of the CAARP would reduce the City of Maywood’s community-wide GHG emissions.

As such, impacts would be less than significant, and no mitigation measures are required.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-42 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 Cumulative Impacts
As discussed above, the CAARP is a policy document, the approval of which would not directly result in the development of land uses and would not directly result in GHG emissions. The purpose of the CAARP is to reduce the City’s community-wide GHG emissions and to enhance the community’s resilience to the anticipated impacts of climate change. GHG emissions may result from future CAARPrelated projects and would be required to undergo an environmental review pursuant to CEQA, on a caseby-case basis.

Analysis of GHG emissions is cumulative in nature because impacts are caused by cumulative global emissions and additionally, climate change impacts related to GHG emissions do not necessarily occur in the same area as a project is located. The emission of GHGs by a single development project into the atmosphere is not necessarily an adverse environmental effect. Rather, it is the increased accumulation of GHGs from more than one project and many sources in the atmosphere that may result in global climate change. The resultant consequences of that climate change can cause adverse environmental effects. A project’s GHG emissions typically would be very small in comparison to state or global GHG emissions and, consequently, they would, in isolation, have no significant direct impact on climate change.

The state has mandated a GHG emissions target of reducing statewide emissions to 40 percent below 1990 levels by 2030, and 80 percent below 1990 levels by 2050 even while statewide population and commerce are predicted to continue to expand. In order to achieve this goal, CARB has established and is implementing regulations to reduce GHG emissions statewide. Currently, there are no adopted CARB, SCAQMD, or County significance thresholds or specific numeric reduction targets applicable to the CAARP, and no approved policy or guidance to assist in determining significance at the cumulative level.

Additionally, there is currently no generally accepted methodology to determine whether GHG emissions associated with a specific project represent new emissions or existing, displaced emissions. In addition, the CAARP’s incorporation of Adaptation and Resilience measures provides a significant, long-term cumulative benefit that further supports state and regional GHG reduction efforts.

Therefore, consistent with CEQA Guidelines Section 15064(h)(3),36 the City, as lead agency, has determined that the CAARP’s contribution to cumulative GHG emissions and global climate change would be less than significant if the CAARP is consistent with the applicable regulatory plans and policies to reduce GHG emissions: 2022 Scoping Plan and SCAG’s Connect SoCal 2024. As evaluated above, given that the Project would not conflict with applicable GHG reduction plans, policies, and regulations, adoption of the CAARP would result in less than signfiicant cumulatively considerable impacts and no mitigation measures are required.
36 As discussed, the CEQA Guidelines were amended in response to SB 97. In particular, the CEQA Guidelines were amended to specify that compliance with a GHG emissions reduction program renders a cumulative impact insignificant. Per CEQA Guidelines Section 15064(h)(3), a proposed project’s incremental contribution to a cumulative impact can be found not cumulatively considerable if a proposed project will comply with an approved plan or mitigation program that provides specific requirements that will avoid or substantially lessen the cumulative problem within the geographic area of a project. To qualify, such a plan or program must be specified in law or adopted by the public agency with jurisdiction over the affected resources through a public review process to implement, interpret, or make specific the law enforced or administered by the public agency. Examples of such programs include a “water quality control plan, air quality attainment or maintenance plan, integrated waste management plan, habitat conservation plan, natural community conservation plan, [and] plans or regulations for the reduction of greenhouse gas emissions.”

Discussion
a) Less Than Significant Impact. The CAARP is a policy document and does not propose any actions that would create a hazard through the routine transport, use, or disposal of hazardous materials. It is possible that any future CAARP-related project would result in construction activities that would require the use of materials that include on-site fueling/servicing of construction equipment and the transport of fuels, lubricating fluids, and solvents. The CAARP’s Clean Energy (E) strategy, Green Buildings and Infrastructure (B) strategy, and Zero-Emission Vehicles (V) strategy would also involve the use of materials like refrigerants or battery components, but these would be handled according to existing safety regulations. These materials are not acutely hazardous, and all storage, handling, and disposal of these materials are regulated by the California Department of Toxic Substances Control (DTSC), United States Environmental Protection Agency (EPA), Occupational Safety & Health Administration (OSHA) and City policies. The transport, use, and disposal of construction-related hazardous materials associated with any CAARP-related project would occur in conformance with applicable local, state, and federal regulations governing such activities. Therefore, the Project would not create a significant hazard to the public or the environment through the routine transport, use, or disposal of

City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-44 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 hazardous materials thus impacts would be less than significant, and no mitigation measures would be required.
b) Less Than Significant Impact. As discussed above, the CAARP is a policy document and does not propose land use, zoning, or physical changes in the City and would instead promote sustainable infrastructure development and strategies to reduce GHG emissions in the City. The CAARP does not propose new development that would involve the routine use of hazardous materials. However, any CAARP-related project would involve the temporary use of hazardous materials such as vehicle fuels and fluids that would be released should an accidental leak or spill occur. However, these types of materials are not considered acutely hazardous, and storage, handling, and disposal of these materials are regulated by the DTSC, the USEPA, and the OSHA.

Any use of potentially hazardous materials during construction of any CAARP-related project would comply with all local, state, and federal regulations regarding the handling of potentially hazardous materials, including Title 49 of the Code of Federal Regulations, Title 22, Division 4.5 of the CCR, and the National Pollutant Discharge Elimination System (NPDES) permitting program.

In addition, the CAARP’s Measure A5 would enhance the City’s ability to respond to and mitigate upset conditions by improving the City’s emergency response capabilities and protecting critical infrastructure, which would minimize the impact of any accidental hazardous material release. Therefore, the Project would not create a significant hazard to the public or the environment through foreseeable upset or accident conditions involving the release of hazardous materials into the environment thus impacts would be less than significant, and no mitigation measures would be required.
c) Less Than Significant Impact. There are four elementary schools, a high school, a magnet school, and a charter kindergarten program within the City.37 The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City that would involve hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school. The types of physical change that would be associated with the CAARP do not involve emissions of hazardous material, and in fact, some aspects of implementation of the CAARP would help to reduce toxic air contaminants through the Clean Energy (E) strategy and the Zero-Emissions Vehicles (V) strategies. Any CAARP-related project with the potential for hazardous emissions or waste would be subject to environmental review as a case-by-case basis. Therefore, the Project would not emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within onequarter mile of an existing or proposed school, thus impacts would be less than significant, and no mitigation measures would be required.

City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-45 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 d) No Impact. According to the State Water Resources Control Board (SWRCB) Geotracker database, there are no active hazardous material sites within the City. 38 Since the CAARP would
serve as a policy document guiding GHG emission reduction in the City, any CAARP-related project would be required to comply with relevant federal and state regulations designed to avoid public health and environmental impacts. Therefore, the Project would not be located on a site which is included on a list of hazardous material sites compiled pursuant to Government Code Section 65962.5 and, as a result, would not create a significant hazard to the public or the environment, thus no impact would occur, and no mitigation measures would be required. e) No Impact. The City is not located within an airport land use plan, or where such a plan has not been adopted, within two miles of a public airport or public use airport. As mentioned above, the CAARP is a policy document which proposes measures to reduce GHG emissions in the City.

The CAARP does not propose any land use, zoning, or physical changes in the City. Therefore, the Project would not be located in an airport land use plan, or where such a plan has not been adopted, within two miles of a public airport or public use airport, which would result in a safety hazard or excessive noise for people residing or working in the area, thus no impact would occur, and no mitigation measures would be required.
f) No Impact. The CAARP is a policy document intended to reduce GHG emissions in the City.

The CAARP does not propose land use, zoning, or physical changes in the City nor would it facilitate new development that would interfere with adopted emergency plans. Any future CAARP-related projects would have the potential to require lane closures (i.e., Smart Mobility and Active Transportation (M) strategy improvements) and may impact traffic and vehicle speeds on the affected roadways; however, these impacts would be temporary and safe access to roadways would be maintained throughout project construction. Furthermore, CAARP-related projects involving work in the public right-of-way would be required to coordinate with the City through the street use permits, encroachment permit review and construction permitting processes to confirm appropriate construction staging and adequate vehicular and pedestrian access on adjacent roadways and that emergency evacuation routes would not be impacted. In addition, the CAARP’s Measure A5 would support and enhance the implementation of adopted emergency response and evacuation plans by identifying, prioritizing, and upgrading critical infrastructure and improving coordination. Therefore, the Project would not impact implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan, thus no impact would occur, and no mitigation measures would be required. g) No Impact. The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City that would be subject to wildland fire, nor would it result in other physical changes to the environment that would increase the risk of wildfires.

Cumulative Impacts
The CAARP is intended to facilitate GHG reductions within the City of Maywood by implementing various strategies and actions that are consistent with the CAARP as part of future development. The only other related projects in the region with the potential to contribute to cumulative effects in conjunction with the CAARP are other CAPs and similar GHG reduction plans. Hazards and hazardous materials impacts are typically site-specific in nature. Future CAARP-related projects, in combination with other cumulative projects that occur to accommodate the City’s anticipated population, employment, and housing growth, are not anticipated to contribute to cumulative hazards and hazardous materials impacts with adherence to applicable City General Plan policies and local, state, and federal regulatory requirements related to the handling, storage, use, disposal, and cleanup of hazardous materials. The CAARP is a policy document and does not propose any land use, zoning, or physical changes in the City that would be subject to wildfire. The CAARP also does not propose new development and would not interfere with an emergency response plans. The CAARP’s inclusion of Measure A5 would act to proactively manage and mitigate the cumulative risk of all hazards by strengthening community preparedness, improving response capabilities, and protecting essential public services. Any construction activities associated with the CAARP would require the use of materials that are not acutely hazardous and all handling, storage, and disposal would be regulated by the DTSC, the EPA, the OSHA, and City policies. The CAARP also does not propose actions that would involve hazardous emissions or handle hazardous materials within one-quarter mile of a school. Implementation of the CAARP would not create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials or through upset or accident conditions. Therefore, implementation of the CAARP would result in a less-than-significant cumulative impact related to hazards and hazardous materials. 39 CALFIRE, 2025.

Discussion
a) Less Than Significant Impact. The CAARP is a policy document and does not propose land use or zoning changes in the City that would increase urban runoff in areas where pollutants would be carried into stormwater systems. The CAARP does propose actions that, depending on their implementation, would have benefits for surface or groundwater quality. The Water Conservation and Reuse (W) strategy, which promotes green infrastructure, water reuse, and efficiency, would have long-term benefits for water quality in the City. However, any future CAARP-related project would result in some earth disturbance that would have the potential to result in the increase amount of runoff or pollutants in runoff. Thus, any future CAARP-related project would be required to obtain and comply with an NPDES to control stormwater discharges. If appropriate, any CAARP-related project would be subject to a Stormwater Pollution Prevention Plan (SWPPP) and/or be required to incorporate Best Management Practices (BMPs) during construction activities to reduce potential impacts to water quality. Therefore, the Project would not violate any water quality standards or waste discharge requirements or otherwise substantially degrade surface or groundwater quality thus impacts would be less than significant, and no mitigation measures would be required.

City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-48 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 b) No Impact. The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City, which would not result in an increase demand for groundwater. The CAARP does not propose development that would require large expanses of impervious surfaces, including areas that are important for groundwater recharge. The CAARP would instead promote sustainable infrastructure development and strategies to reduce GHG emissions in the City.

Therefore, the Project would not decrease groundwater supplies or interfere with groundwater recharge such that the Project may impede sustainable groundwater management of the basin thus no impact would occur, and no mitigation measures would be required. c.i) No Impact. The CAARP does not propose land use, zoning, or physical changes in the City or large expanses of impervious surfaces or other actions that would generate substantial erosion or siltation on-or off-site. Any future CAARP-related projects would have the potential to result in substantial erosion or siltation on- or off-site but these individual projects would be required to undergo an environmental review pursuant to CEQA, on a case-by-case basis. The CAARP is supportive of actions to manage runoff, such as Measure A4, which would help to mitigate potential erosion. Therefore, the CAARP, serving as a policy document, does not propose development that would substantially alter the existing drainage pattern of a site or area, including through the alteration of the course of a stream or river or through the addition of impervious services, in a manner which would result in substantial erosion or siltation on- or offsite, thus no impact would occur, and no mitigation measures would be required. c.ii) No Impact. As mentioned above, the CAARP is a policy document and does not propose land use, zoning, or physical changes in the City or large expanses of impervious surfaces or other actions that would generate increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site. Any future CAARP-related project would have the potential to result in substantial increase or amount of surface runoff but these individual projects would be required to undergo an environmental review pursuant to CEQA, on a case-by-case basis. Furthermore, policies with the CAARP, such as promoting Measure A4, would work to increase infiltration and reduce the rate and amount of surface runoff, which has a beneficial effect on mitigating potential flooding. Therefore, the CAARP, serving as a policy document, does not propose development that would substantially alter the existing drainage pattern of a site or area, including through the alteration of the course of a stream or river or through the addition of impervious services, in a manner which would substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site thus no impact would occur, and no mitigation measures would be required.
c.iii) No Impact. The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City or large expanses of impervious surfaces or other actions that would create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff. Any future CAARP-related project would have the potential to create or contribute runoff water that would exceed existing or planned stormwater drainage systems but these individual projects would be required to undergo an environmental review pursuant to CEQA, on a case-by-case basis.

The CAARP does not propose development that would alter the existing drainage pattern of a site or area, including through the alteration of the course of a stream or river or through the addition of impervious services, in a manner which impede or redirect flood flows thus no impact would occur, and no mitigation measures would be required. d) No Impact. According to the Safety Element, the City of Maywood is not at risk of flooding per the current Federal Emergency Management Agency (FEMA) flooding map. 41 There are also no mapped floodplains in the City, and no land uses within the City are considered at risk of flooding.42 The City is immediately adjacent to the Los Angeles River, and while the southeast portion of the City is within an area of reduced flood risk due to levee failure, the CAARP is a policy document and does not propose land use, zoning, or physical changes to the City. Any future CAARP-related project would be subject to review against current FEMA maps, and the risk of pollutant release due to inundation would undergo a separate, project-specific environmental review. Therefore, the CAARP would not release pollutants due to project inundation within a flood hazard, tsunami, or seiche zone, thus no impact would occur, and no mitigation measures would be required.
e) No Impact. The CAARP measures focus on GHG reduction efforts and sustainability. The CAARP would not interfere with or obstruct the implementation of water quality standards, waste discharge requirements, or otherwise substantially degrade surface or groundwater quality, thus no impact would occur, and no mitigation measures would be required.

XI. LAND USE AND PLANNING — Would the project:
a) Physically divide an established community? ☐ ☐ ☐ ☒
b) Cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental
effect?
☐ ☐ ☐ ☒
Discussion
a) No Impact. The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City that would divide an established community. The CAARP outlines a strategic roadmap with clear goals, innovative strategies, and actionable measures across various sections including transportation, electricity, natural gas, solid waste, wastewater treatment, and energy use for water conveyance. The CAARP’s objective is also to enhance the City’s resilience to climate change impacts through engaging planning practices. Therefore, the Project would not physically divide an established community thus no impact would occur, and no mitigation measures would be required.
b) No Impact. The CAARP is a policy document containing measures that are consistent with the City’s General Plan and that are designed to reduce adverse environmental impacts associated with climate change. Nonetheless, implementing the CAARP would require some modification of existing policies, including developing and implementing new programs, projects, or modifying existing ones. To implement these policies and measures, the City’s Municipal Code and other applicable City policies would need to be amended to reflect new or modified requirements.

However, where modifications of existing policies are implemented, the CAARP measures would result in greater avoidance or reduction of environmental effects caused by climate change.

Therefore, the Project would not cause a significant impact due to a conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an environmental effect thus no impact would occur, and no mitigation measures would be required.

Cumulative Impacts
The CAARP would establish measures and actions to reduce GHG emissions within the City and reduce vulnerability to the effects of climate change. The CAARP does not propose specific development and would not involve land use, zoning, or physical changes to implement its proposed measures or incorporate them into future projects. The CAARP is a policy document containing measures that are consistent with the City’s General Plan and other existing policy documents. However, any policy change proposed as a result of the CAARP would be consistent with the intent of the goals and policies already established within the City’s General Plan and the Municipal Code and would not cumulatively contribute to the division of communities or conflict with land use policies related to environmental protection.

Cumulative projects, including those implemented under the CAARP, would be required to adhere to City development regulations and the General Plan policies to minimize environmental impacts. Therefore, the Project would result in no cumulative impact related to land use and planning.

Discussion
a-b) No Impact. There are no mapped mineral resource zones in the City of statewide or regional significance.43 In addition, no areas in the City are designated as mineral resource extraction areas by the State and no mineral extraction operations occur within the City. Furthermore, the CAARP is a policy document focused on GHG reduction and climate resilience measures (such as clean energy, green buildings, zero-emission vehicles, and water conservation) and does not propose land use, zoning, or physical developments. The CAARP would also not facilitate additional urban growth or infrastructure development projects within the City that would result in the loss of availability of a known mineral resource that would be of value to the region and the residents of the state or locally-important mineral resource recovery site delineated on a local general plan, specific plan, or other land use plan. Therefore, the Project would result in no impact related to mineral resources, and no mitigation measures would be required.

☐ ☐ ☒ ☐
b) Generation of excessive groundborne vibration or
groundborne noise levels? ☐ ☐ ☒ ☐
c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?
☐ ☐ ☒ ☐
Discussion
a) Less Than Significant Impact. The City is located in southeastern Los Angeles County. The City’s CAARP is a policy document designed to reduce GHG emissions and enhance community resilience to climate change. Adoption and implementation of the CAARP would not result in land use changes, zoning changes, or result in the approval of any specific physical development.

While future CAARP-related projects would be implemented under CAARP’s various strategies, such as improvements to pedestrian and bicycle infrastructure (Measure M3), these projects would be limited to existing developed areas. Future projects would be required to comply with City noise control requirements in the Municipal Code Title 5, Chapter 23 (Noise Control) including time of day restrictions, noise level requirements, variance procedures, and abatement orders, as applicable. Future projects implemented under the CAARP requiring discretionary approval would also be subject to separate environmental review under the CEQA, ensuring consistency with the City’s noise thresholds for construction and operations, if applicable.

Because CAARP is a policy document and does not propose specific physical developments, the Project would not have a substantial adverse effect on the ambient noise within the vicinity of any project under CAARP and construction and operational noise would be less than significant, and no mitigation measures are required.
b) Less Than Significant Impact. The CAARP is a policy document that outlines a strategic roadmap for reducing GHG emissions and enhancing community resilience. As a policy document, the CAARP would not create new sources of vibration. However, adoption and implementation of the CAARP would lead to future CAARP-related projects that would include physical changes, such as the installation of solar panels (Measure E2) or electric vehicle (EV) charging infrastructure (Zero-Emission Vehicles Strategy (V)). The individual projects requiring discretionary approval would be subject to a separate environmental review under CEQA. Future infrastructure development or redevelopment resulting from the CAARP would be required to comply with applicable City regulations and standards, including those related to vibration.

Because the CAARP is a policy document and does not propose specific physical developments,

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-54 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 the Project would not cause the generation of excessive groundborne vibration or groundborne noise levels and impacts would be less than significant, and no mitigation measures are required. c) Less Than Significant Impact. The City is not located within the vicinity of a private airstrip, or heliport or helistop. The Compton/Woodley Airport is located approximately 6.8 miles southwest of the City, the Hawthorne Airport is located approximately 8.8 miles southwest of the City, the San Gabriel Valley Airport is located approximately 10.1 miles northeast of the City, the Los Angeles International Airport is approximately 10.7 miles southwest of the City, and the Hollywood Burbank Airport is located approximately 15.7 miles to the northwest of the City.

Therefore, implementation of the CAARP would not expose people residing or working in the project area to excessive noise levels and impacts would be less than significant, and no mitigation measures are required.

The CAARP is intended to facilitate GHG reductions within the City of Maywood by implementing various strategies and actions that are consistent with the CAARP as part of future development. The only other related projects in the region with the potential to contribute to cumulative effects in conjunction with the CAARP are other CAPs and similar GHG reduction plans. The CAARP would establish measures and actions to reduce GHG emissions within the City and reduce vulnerability to the effects of climate change. The CAARP does not propose specific development and would not result in the implementation of land use, zoning, or physical changes. Future implementing CAARP-related projects, in combination with other cumulative projects, requiring discretionary approval would be subject to a separate environmental review under CEQA, ensuring consistency with the City’s existing zoning and design regulations in addition to noise and vibration thresholds for construction and operations if applicable. Therefore, the Project would result in a less than significant cumulative impact related to noise and vibration.

As discussed above, City is not located within the vicinity of a private airstrip, land use plan, or public or public use airport. Since future projects developed under the CAARP would result in a less than significant impact, even if other projects were to be developed within the vicinity of an airport, impacts would still be less than significant because future development facilitated by adoption of the CAARP would not in construction or operational impact within the vicinity of an airport and would not increase noise impacts. Therefore, cumulative noise impacts would not expose people residing or working in the project area to excessive noise levels in the vicinity of an airport. Cumulative impacts would be less than significant and no mitigation measures are required.

XIV. POPULATION AND HOUSING — Would the project:
a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new
homes and businesses) or indirectly (for example,
through extension of roads or other infrastructure)?
☐ ☐ ☒ ☐
b) Displace substantial numbers of existing people or
housing, necessitating the construction of replacement
housing elsewhere?
☐ ☐ ☒ ☐
Discussion
a-b) Less Than Significant Impact. As mentioned above, the CAARP is designed primarily to reduce GHG emissions and enhance the community’s resilience to climate change by incorporating measures and strategies focused on sustainable growth. The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City that would result in new housing or jobs or that would displace existing residents or housing. In addition, the CAARP does not propose new infrastructure, such as roadways or utilities, which would indirectly lead to new population growth or development.

However, the CAARP identifies the unintentional risk of displacement for tenants as an equity concern. Building improvements and solar upgrades proposed in the CAARP aimed at reducing emissions could indirectly increase displacement risks in the City if landlords pass the costs of building upgrades onto tenants through rent increases or vacate units and later provide those same units at a higher market rate. To address this potential displacement, the CAARP incorporates specific actions to address displacement risks within the Green Buildings and Infrastructure (Measures B1 and B2) and Clean Energy (Measure E2) strategies. Therefore, the Project would not have the potential to indirectly displace substantial numbers of existing people or housing, as the CAARP addresses displacement risks through integrated equity measures and actions. Thus, impacts would be less than significant, and no mitigation measures would be required.

Future CAARP-related projects, in combination with other cumulative projects that occur to accommodate the City’s anticipated population, employment, and housing growth, are not anticipated to displace people or housing nor induce substantial unplanned population growth within the City. The CAARP, however, includes measures/actions within its strategies to address the equity concerns that

ii) Police protection? ☐ ☐ ☐ ☒
iii) Schools? ☐ ☐ ☐ ☒
iv) Parks? ☐ ☐ ☐ ☒
v) Other public facilities? ☐ ☐ ☐ ☒
Discussion
a.i-v) No Impact. The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City that would result in increases in population or new employment opportunities that would induce population growth. The CAARP would not require the construction of new or physically altered governmental facilities to serve additional residents, the construction of which would cause significant environmental impacts. The CAARP focuses on creating clear goals, innovative strategies, and actional measures across various sectors including transportation, electricity, natural gas, solid wastewater treatment, and energy use for water conveyance. The CAARP would serve as a strategic roadmap to reduce GHG emissions in the City and address environmental impacts as a result of climate change.

However, the CAARP does include measures and implementing actions that would encourage future physical changes in the City, more specifically, upgrades to existing public facilities and infrastructure to enhance climate resilience. These upgrades would be prioritized phased investments such as the City Hall, the Teen Center, YMCA, and Cesar Chavez Library for phased investments in energy efficiency, solar, battery storage, and EV infrastructure. Other measures that would result in physical changes to governmental facilities include cool roofs and pavements, and the expansion of bicycle and pedestrian facilities which are also aimed at reducing GHG emissions in the City. However, these targeted physical alternations proposed in the CAARP are not intended to increase service capacity for a new population. Therefore, the Project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new of physically altered government facilities, the construction of which would cause significant environmental impacts, in order to maintain acceptable service ratios, response times, or other performance objectives for fire protection, police protection, schools, parks, and other public facilities, thus no impacts would occur, and no mitigation measures would be required.

Therefore, implementation of the CAARP would not result in substantial cumulative need to expand public services facilities. Rather, the CAARP includes measures to reduce GHG emissions and address environmental impacts as a result of climate change by improving the resilience and efficiency of existing public facilities and infrastructure. Therefore, the Project would not result in a cumulative impact related to public services.

facilities such that substantial physical deterioration of the facility would occur or be accelerated?
☐ ☐ ☐ ☒
b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the
environment?
☐ ☐ ☐ ☒
Discussion
a-b) No Impact. The City has two major parks (Maywood Park and the Riverfront Park) and three pocket parks (Pixley Park, Pine Avenue Park, and Benito Juarez Park), which provide recreational facilities and opportunities in the City. 44,45 As a policy document, the CAARP does not propose land use, zoning, or physical changes to the City which would increase population, employment, or housing, and therefore would not induce substantial population growth that would increase the use of existing neighborhood and regional parks or other recreational facility or require the construction or expansion of recreational facilities, which would lead to physical deterioration.

In addition, the CAARP is consistent with and complementary to the City’s General Plan Open Space Element policies, which aim to increase tree canopy in the City. The CAARP promotes active transportation and improvements to sidewalks with more greenery (Measure M3), which has a direct positive impact on park quality and urban green spaces in the City by mitigating extreme heat and improving air quality. The CAARP proposed measures and actions are beneficial and are not considered an adverse physical effect on the environment. Therefore, the Project would not increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated nor would it increase recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment, thus no impact would occur, and no mitigation measures would be required.

XVII. TRANSPORTATION — Would the project:
a) Conflict with a program plan, ordinance or policy
addressing the circulation system, including transit,
roadway, bicycle and pedestrian facilities?
☐ ☐ ☒ ☐
b) Would the project conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? ☐ ☐ ☐ ☒
c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)?
☐ ☐ ☒ ☐
d) Result in inadequate emergency access? ☐ ☐ ☐ ☒
Discussion
a) Less Than Significant Impact. The City has adopted several plans and policies addressing the circulation system, including the City’s General Plan Circulation Element, which establishes the overarching vision for the circulation system in the City. The CAARP would be consistent with these policies by promoting sustainable, multimodal transportation, and alternative modes of transportation. The CAARP measures would advance active transportation and public transit and reduce vehicle miles traveled (VMT), along with associated air pollutants and GHG emissions.

Specifically, the CAARP would provide pedestrian network improvements to increase sidewalk coverage and improve pedestrian amenities to encourage walking instead of driving (Measure M3). The CAARP also encourages the expansion of bike facilities to encourage a mode shift from vehicles to bicycles by providing safe bike infrastructure, such as bike paths and lanes (Measure M3). Also, the CAARP encourages end-of-trip bicycle facilities by installing bicycle parking and lockers at key destinations, providing a secure place for cyclists to store their bikes (Measure M3). Lately but not lease, the CAARP would expand bikeway network to create an extensive network of bike paths and lanes to provide more options for cyclists (Measure M3).

Furthermore, the CAARP would also be thoughtfully integrated within existing state planning and funding efforts that connect land use and transportation, consistent with Senate Bill (SB) 375, which promotes sustainable communities by linking regional transportation plans with land-use decisions, and SB 379, which requires local governments to incorporate climate adaptation and resiliency strategies into their general plans. Therefore, the Project would not conflict with a program, plan, ordinance, or policy addressing the circulation system, including transit roadway, bicycle and pedestrian facilities and impacts would be less than significant, and no mitigation measures would be required.
b) No Impact. The CEQA Guidelines Section 15064.3 suggests that VMT is the most appropriate measure of impact on travel demand. The CAARP focuses on encouraging alternative transportation modes and reducing VMT. These measures, such as extending transit network coverage (Measure M1), provide end-of-trip bicycle facilities (Measure M3), and expand the bikeway network (Measure M3), would directly benefit alternative transportation, and would be consistent with CEQA Guidelines, Section 15064.3(b). Therefore, the Project would not conflict

c) Less Than Significant Impact. Any CAARP-related projects would primarily be constructed in developed areas or along existing roadways and would not change the existing configuration of the major roadways in a manner that would create hazards. The CAARP proposes actions and supporting measures in an effort to provide alternative modes of transportation and reduce the number of VMT throughout the City. The GHG measures that encourage a shift in transportation modes and reduction in travel demand would result in minor changes to the existing streetscape.

Streetscape improvements, which would include the addition of pedestrian and bicycle facilities would be required to comply with City public improvement and street standards, which are designed to avoid any increase in hazards due to geometric design features or incompatible uses.

Therefore, the Project would not increase hazards due to a geometric design feature or incompatible uses thus impacts would be less than significant, and no mitigation measures would be required.
d) No Impact. As previously mentioned, the CAARP does not include any land use or zoning changes in the City that would result in changes to the access provided by the City’s transportation network. Any CAARP-related project requiring discretionary approval would be required to comply with applicable local policies and undergo project-specific environmental review. The CAARP also includes Measure A5, which enhances the City’s overall emergency response capabilities. Therefore, the Project would not result in inadequate emergency access thus no impact would occur, and no mitigation measures would be required.

agency shall consider the significance of the resource
to a California Native American tribe.
☐ ☐ ☒ ☐
Discussion
a.i & a.ii) Less Than Significant Impact.

On November 18, 2025, the City submitted notification and request to consult letters to eleven (11) individuals and organizations pursuant to AB 52. In particular, AB 52 letters were sent to the following California Native American tribes and individuals:
• Andrew Salas, Gabrieleño Band of Mission Indians ‒ Kizh Nation • Christina Swindall Martinez, Gabrieleño Band of Mission Indians ‒ Kizh Nation • Anthony Morales, Gabrieleño Tongva San Gabriel Band of Mission Indians • Charles Alvarez, Gabrielino ‒ Tongva Tribe
• Robert Dorame, Gabrielino Tongva Indians of California Tribal Council • Christina Conley, Gabrielino Tongva Indians of California Tribal Council • Sandonne Goad, Gabrielino/Tongva Nation
• Jessica Valdez, Soboba Band of Luiseño Indians
• Joseph Ontiveros, Soboba Band of Luiseño Indians
• Lovina Redner, Santa Rosa Band of Cahuilla Indians
• Sam Dunlap, Gabrielino-Tongva Tribe
No responses were received from any of these individuals pursuant to AB 52. Therefore, AB 52 tribal consultation is concluded pursuant to Public Resources Code Section 21080.3.2(b).

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-64 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 Future projects would be required to comply with existing federal, State, and local regulations, and undergo the City’s discretionary review process, where applicable, including completion of subsequent project-level planning and environmental review under CEQA. These projects would similarly require compliance with AB 52 to ensure that tribal cultural resources are properly identified. Therefore, the Project would result in a less than significant impact and no mitigation measures would be required.

Cumulative Impacts
The CAARP is a policy document intended to reduce GHG emissions and enhance community resilience, which is cumulatively beneficial to the region. However, implementation of the CAARP would result in future CAARP-related projects which may involve ground-disturbing activities. When viewed in connection with other probable future development projects in the City—which also require grading and excavation—the CAARP's incremental effect could contribute to a cumulatively considerable impact on tribal cultural resources, as these sites, features, and sacred places may be unearthed and damaged across the City. Since the exact location and scope of future CAARP-related projects is unknown at the time of this Initial Study/Mitigated Negative Declaration, the potential for unidentified tribal cultural resources to be disturbed across the City remains a concern under the cumulative scenario.

Despite this potential for cumulative impact, the CAARP ensures that its incremental contribution is reduced to a less-than-significant level by complying with existing federal, State, and local regulations, and undergoing the City’s discretionary review process, where applicable, including completion of subsequent project-level planning and environmental review under CEQA. By requiring that all CAARPrelated projects adhere to federal, State, and local regulations and the City’s discretionary review process, and consultation with tribes under AB-52, the Project ensures that its contribution to cumulative impacts on tribal cultural resources is minimized. Therefore, the Project’s incremental contribution to cumulative impacts on tribal cultural resources is not cumulatively considerable, resulting in a less than cumulatively considerable impact.

Discussion
a) Less Than Significant Impact. The CAARP is a policy document and does not propose land use or zoning changes to the City which would induce population, employment, or housing growth in the City requiring the relocation or construction of new or expanded water, wastewater treatment, stormwater drainage, natural gas, or telecommunication facilities and impacts would not occur.

However, CAARP-related projects would lead to small-scale construction associated with clean energy and EV infrastructure. Specifically, the CAARP’s Zero-Emission Vehicles (V) strategy, which aims to provide EV infrastructure in the City and which has the potential to result in the relocation or construction of new or expanded electric power of which would cause significant environmental effects. Furthermore, the CAARP’s Adaptation and Resilience measures such as the implementation of backup power for critical facilities, including solar and battery storage systems, and the construction of green infrastructure for enhanced stormwater management will also involve minor construction activities.

Any future CAARP-related projects would involve minor construction, installation, and connection to the existing electric power grid. However, these CAARP-related projects would not require the construction of new or expanded major electric utility infrastructure outside of existing infrastructure or service capacities. These projects would be consistent with the City’s General Plan Circulation Element goals and policies, addressing VMT and supporting alternatives modes of transportation. Since the CAARP does not propose land use or physical development changes in the City which would result in the relocation or construction or new or expanded electric power, of which would cause significant environmental effects, thus impacts would be less than significant, and no mitigation measures would be required.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-66 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 b) No Impact. The CAARP is a policy document that does not include site-specific infrastructure designs or project proposals, nor does it grant entitlements for development that would have the potential to increase water demand. The CAARP contains measures and actions to reduce GHG emissions associated with water distribution, treatment, and transportation, indirectly promoting water use efficiency (Measures W1 and W2). In addition, Measure A4 promotes the use of permeable surfaces and bioswales, which would serve to increase local groundwater recharge and reduce reliance on imported water supplies, further ensuring water sufficiency. Therefore, the Project would have sufficient water available to serve the project and foreseeable development during normal, dry, and multiple dry years, thus no impact would occur, and no mitigation measures would be required.
c) No Impact. The CAARP would not result in new land uses that would generate sanitary wastewater or otherwise contribute to an increase in wastewater treatment requirements. Rather, the CAARP includes measures to reduce energy use and associated GHG emissions for water treatment, transportation, and distribution, which would result in beneficial impacts in the City.

Therefore, the Project would have adequate capacity to serve the Project’s demand in addition to the providers’ existing commitments, thus no impact would occur, and no mitigation measures would be required.
d) No Impact. The CAARP is a policy document focused on GHG reductions and does not propose measures or actions that would result in the construction of new water or wastewater facilities or the expansion of existing facilities. The CAARP includes measures to direct waste from landfills, which supports and helps attain solid waste reduction goals. Any construction waste generated by CAARP-related projects, including building upgrades (Measure A5), would be temporary and managed in accordance with state and local diversion requirements. Therefore, the Project would not generate solid waste in excess of state or local standards or exceed the capacity of local infrastructure or otherwise impact the attainment of solid waste reduction goals, thus no impact would occur, and no mitigation measures would be required. e) No Impact. The CAARP does not recommend any measure or actions that does not comply with applicable solid waste regulations. Instead, the CAARP’s measures are designed to promote compliance and enhance waste reduction efforts, specifically by reducing organic waste through composting and other direction methods (Measure R1). Therefore, the Project would comply with federal, state, and local management and reduction statutes and regulations related to solid waste thus no impact would occur, and no mitigation measures would be required.

XX. WILDFIRE — If located in or near state responsibility areas or lands classified as very high fire hazard severity zones, would the project:
a) Substantially impair an adopted emergency response
plan or emergency evacuation plan? ☐ ☐ ☐ ☒
b) Due to slope, prevailing winds, and other factors,
exacerbate wildfire risks, and thereby expose project
occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire?
☐ ☐ ☐ ☒
c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency
water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment?
☐ ☐ ☐ ☒
d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a
result of runoff, post-fire slope instability, or drainage changes?
☐ ☐ ☐ ☒
Discussion
a-d) No Impact. According to the CALFIRE, the City is located outside a VHFSZ, a LRA, and a SRA.46,47 The CAARP serves as a strategic roadmap for the City to address and reduce GHG emissions. The CAARP is also a policy document and does not propose land use, zoning, or physical changes in the City. As a policy document, the CAARP would implement measures across various sectors including transportation, electricity, natural gas, solid waste, wastewater treatment, and energy use for water conveyance. Since the CAARP does not propose land use, zoning, or physical changes nor would it be located within a high fire hazard zone, the CAARP would have no impacts related to wildfires. Thus, the Project would not be located in or near state responsibility areas or lands classified as VHFSZ, and would not substantially impact an adopted emergency response plan or emergency evacuation plan; due to slope, prevailing winds, or other factors, exacerbate wildfire risks exposing project occupants, to pollutant concentrations from a wildfire or uncontrolled spread of wildfire; require the installation or maintenance of associated infrastructure that may exacerbate fire risk; nor would it expose people or structures to significant risks, including downslope or downstream flooding or landslides. Furthermore, the CAARP’s incorporation of Measure A5 would enhance the City’s overall resilience to disasters, including those related to fire, by upgrading critical facilities. Therefore, no impact would occur, and no mitigation measures would be required.

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-69 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 Cumulative Impacts
The CAARP is intended to facilitate GHG reductions within the City of Maywood by implementing various strategies and actions that are consistent with the CAARP as part of future development. The only other related projects in the region with the potential to contribute to cumulative effects in conjunction with the CAARP are other CAPs and similar GHG reduction plans. Cumulative development anticipated to occur in the City would not result in cumulative impacts related to wildfire because the City is not located within a LRA or SRA fire hazard severity zone. The CAARP is a policy document and does not propose land use, zoning, or physical changes in the City. Any CAARP-related project would also not be located within a LRA or SRA fire hazard severity zone and thus would not generate cumulative impacts regarding wildfire risks. Therefore, the Project would result in no cumulative impact related to wildfire.

XXI. MANDATORY FINDINGS OF SIGNIFICANCE —
a) Does the project have the potential to substantially degrade the quality of the environment, substantially
reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or
prehistory?
☐ ☐ ☒ ☐
b) Does the project have impacts that are individually
limited, but cumulatively considerable? (“Cumulatively
considerable” means that the incremental effects of a
project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? ☐ ☐ ☒ ☐
c) Does the project have environmental effects which will cause substantial adverse effects on human beings,
either directly or indirectly?
☐ ☐ ☒ ☐
Discussion
a) Less Than Significant Impact. The CAARPs purpose is to reduce GHG emissions and enhance community resilience to climate change through various measures and actions related to several sectors, including transportation, electricity, natural gas, wastewater treatment, and energy use for water conveyance. These measures and actions would encourage residents, businesses, and municipal operations to reduce energy and water use, vehicle fuel consumption, VMT, and solid waste generation, and to implement the proposed CAARP strategies to prepare for climate-related hazards in the City. The CAARP also aims to address environmental justice and climate equity, especially for its high-density urban environment and significant Latino population. Key community priorities identified through outreach included improving health, saving money, and enhancing resilience and safety. Specific measures, such as providing electric vehicle charging infrastructure (Measure V1); improving pedestrian networks and bike facilities (Measure M3); and extending transit network coverage (Measure M1), to list a few, are all designed to generate environmental benefits and reduce GHG emissions in the City. Furthermore, Measure A4 promotes urban greening and tree planting, which would enhance ecological function in the City.

As analyzed in this IS/MND, the CAARP does not propose development that would degrade the quality of the environment, eliminate or threaten wildlife habitats or protected species, or eliminate important examples of the major periods of California history or prehistory. Therefore, the Project would have a less than significant impact, and no mitigation measures would be required.
b) Less Than Significant Impact. As discussed in this IS/MND, the CAARP is a policy document and would not result in significant individual or cumulative adverse impacts. Rather, implementation of the CAARP would produce cumulative benefits related to GHG emissions, air quality, the transportation system, energy use, utility demands, and community resiliency. The

3. Initial Study/Environmental Checklist
City of Maywood Climate Action, Adaptation, and Resilience Plan Project 3-71 D202500378.00 Initial Study/Mitigated Negative Declaration January 2026 CAARP would also be consistent with regional efforts such as SCAG Connect SoCal 2024, reinforcing its positive cumulative effect in the City and regionally. The CAARP would achieve these benefits through the seven strategies that target emissions associated with energy, buildings, transportation, water consumption, and waste, and associated measures and actions. The incorporation of the Adaptation and Resilience Chapter of the CAARP ensures the Project’s effects are beneficial when viewed in connection with the effects of climate change, as it proactively incorporates strategies to protect human health and critical infrastructure from future climate hazards, such as extreme heat and flooding. As addressed above, the CAARP would result in an overall less than significant cumulative impact related to aesthetics, agriculture and forestry resources, air quality, cultural resources, energy, GHG emissions, hazards and hazardous materials, hydrology and water quality, land use and planning, mineral resources, noise, population and housing, public services, recreation, transportation, tribal cultural resources, utilities and service systems, and wildfire.
c) Less Than Significant Impact. As detailed above, the CAARP would not result, either directly or indirectly, to substantial adverse effects on human beings. The CAARP’s GHG Reduction Strategies implements seven strategies that target emissions associated with energy, buildings, transportation, water consumption, and waste, and associated measures and actions. In fact, the primary focus of the CAARP’s Adaptation and Resilience Chapter is to reduce substantial adverse effects on human beings by addressing key community priorities. Furthermore, implementation of CAARP-related projects and actions may require additional CEQA review once project specifications, such as site location are identified, and potential environmental impacts would be determined on case-by-case basis. The CAARP would serve as a pathway to reduce operational GHG emissions and would result in other positive environmental and sustainability benefits. These benefits include a reduction in building energy and water consumption, VMT, as well as improved air quality and resiliency to the effects of climate change and natural disasters. Specifically, the CAARP promotes measures like establishing public cooling centers, implementing home cooling efficiency incentives, and enhancing urban greening, all of which directly improve human health and safety by mitigating the effects of climate change. Therefore, the Project would result in a less than significant impact related to potential adverse effects on human beings.

Climate Action, Adaptation, and Resilience Plan Assessment September 2023 Phase 1 – Final
SECTION 1
Overview

1.1 Background
In response to policy initiatives from federal and state leadership, local governments have been developing programs to address the impacts of climate change on communities. These efforts play a vital role in mitigating climate change and equipping communities to adapt to anticipated changes. The City of Maywood, due to its unique environmental factors—such as its geographic location, vulnerability to flooding and extreme heat, proximity to industrial facilities and pollution sources, and closeness to freeways—is considered to be more susceptible to climate change than other communities in the state. As a high-density city with a significant Latino population, a 25% poverty rate, and high exposure to pollution, Maywood recognizes the importance of environmental justice and climate equity.

To address these concerns, the City is pursuing development of a Climate Action, Adaptation, and Resiliency Plan (CAARP) that would provide a comprehensive framework to emphasize the social, environmental, and economic benefits of reducing community greenhouse gas (GHG) emissions while increasing resilience to climate change impacts. This assessment builds a foundation for building the CAARP for the City of Maywood.

1.2 Purpose of this Assessment
This assessment serves as “Phase 1” for the development of the CAARP for the City of Maywood. It establishes the fundamental policy and technical groundwork for the comprehensive plan to be completed (“Phase 2”). As part of Phase 1, this assessment offers a detailed examination of current conditions, the impacts of climate change, community vulnerabilities, baseline GHG emissions, and trend analyses. Additionally, the document presents GHG projections and proposes reduction targets. The concluding section of the assessment presents recommendations for Phase 2 of the project, including the CAARP's organization, next steps for strategy development, areas for further analysis, and potential funding opportunities to support Maywood's journey towards a sustainable, equitable, and resilient future.

The development of the CAARP through this Phase 1 assessment aligns with significant state planning priorities, which guide investments and funding in climate action and adaptation. These priorities encompass a wide range of areas, including climate change resilience and adaptation, energy conservation and renewable sources, water and water systems, waste and recycling, green infrastructure, parks, urban forestry, and agriculture, as well as green business and industry. Phase 2 will build on this work to have a completed CAARP, to serve as a roadmap for the City of Maywood and its residents, detailing how to reduce GHG emissions (climate action) throughout the community and enhance the city's capacity to prepare for and mitigate the impacts of climate change (climate adaptation). By implementing this plan, Maywood aims to create a more sustainable, equitable, and resilient community for current and future generations.

SECTION 2
Community Outreach and Engagement

2.1 Summary of Approach
Meaningful climate planning and action is grounded in the needs and priorities of community members. The City of Maywood partnered with the Institute for Local Government (ILG) to develop a community engagement approach that meets the unique needs of Maywood’s community.

Public engagement methods included a combination of in-person and online surveying and virtual focus groups. Designed to facilitate participation from diverse community members, the project team prioritized community education to inform residents about the CAARP, the planning process, and the reasons for asking for their input. All materials were also translated into Spanish.

The survey was made available on the City’s CAARP webpage and social media accounts, in both English and Spanish, and asked participants for input on climate action priorities and challenges related to clean water, air quality, clean transportation, energy, and more. In addition to online distribution, the project team went to the community by exploring opportunities to connect in person, including the city’s Trunk or Treat Halloween event, tree-planting events, food distribution events at the YMCA, and Maywood Workforce Program events.

Additionally, the project team held a focus group with high school students from the Maywood Center for Enriched Studies (MaCES) Roots and Shoots Club. MaCES Roots and Shoots Club is a school environmental club focused on environmental and humanitarian work. This involves educating others, tree plantings, and gardening projects.

Through the engagement process, the city built and strengthened connections to the YMCA, Amigos de los Rios, MaCES, and with other community leaders. The project team thanks participants for their time and contributions to this project. The City of Maywood looks forward to the opportunity to more deeply engage with and learn from the community on climate action planning in the future, through educational workshops and trainings for Phase 2 of the CAARP.

2.2 Key Takeaways
Both the survey and focus group served as tools to shape the direction and policies of the Climate Action Adaptation and Resilience Plan. Just as all cities in California are very different, the ways that we can reduce our greenhouse gas emissions can also be different in every community. The City of Maywood is considered more vulnerable to climate change than other communities in the state due to environmental factors, including geographic location and a landscape that is prone to flooding and extreme heat, proximity to industrial facilities that contribute to pollution, and proximity to freeways, among other factors. But there are also a lot of opportunities because of the people who live in Maywood. The community’s values, efforts, and choices help the City

decide how to fund and prioritize projects and programs that help to reduce greenhouse gas emissions in our community.

The engagement not only helped to identify community priorities and needs around climate planning; they also illuminated the opportunity for increased and ongoing engagement, education, and action with the community on climate and sustainability topics. The survey received 110 responses, with 24 responses being submitted in Spanish. 93.5% of survey respondents stated that it is very important that Maywood is environmentally responsible. As co-benefits to greenhouse gas reduction strategies, respondents ranked improving health (81%) as the most important, followed by saving money (53%), improving resilience/safety (51%), create jobs/improve economy (49%), and improving equity (32%). These results are shown in Figure 1.

Air quality, extreme heat, and drought and water supply are among the community’s top areas of concern, shown in Figure 2. Respondents ranked water-saving projects, park improvements, energy efficiency/renewable energy projects, and projects to mitigate heat as priorities they would like to see Maywood take on through its climate action efforts.

SECTION 3
GHG Emissions Analysis

3.1 Background
The City of Maywood’s 2015 community greenhouse gas (GHG) inventory represents an update to the City’s baseline community GHG Inventory for the calendar year 2010, which was prepared as a component of the CAP Framework developed by the GCCOG.1 The City’s community inventory quantifies the GHG emissions that occur throughout a calendar year from activities within the City by residents, businesses, and the City government. The community inventory provides an understanding of where GHG emissions originate and informs the development of effective strategies and actions to reduce emissions. In response to country- and state-specific goals for reducing GHG emissions, myriad strategies for monitoring and addressing emissions have emerged. These have included regulatory approaches such as mandatory reporting for significant sources of GHG emissions and caps on emission levels, as well as market-based mechanisms, such as cap-and-trade. Voluntary actions are also increasing, such as conducting emissions inventories, implementing practices to reduce emissions, and purchasing offsets and renewable energy certificates. As state and federal policies regulating GHG emissions continue to emerge, more requirements to reduce emissions are expected.

Given the increasing regulation of GHG emissions and rising interest from the public and the City’s stakeholders, it is in the local government’s best interest to understand and manage the GHG emissions being generated by the community. Having knowledge of its GHG emissions better prepares the City for future national and/or regional climate change policies and informs strategies for achieving numerous sustainability goals.

The GHG emissions inventory provides the following:
• Identifies sources of GHG emissions across the sectors of energy, transportation, solid waste disposal, wastewater treatment, water conveyance, and refrigeration; • Quantifies levels of emissions in carbon dioxide equivalents (CO2e), using standard accounting protocols;
• Establishes a baseline level of emissions from which to set reduction goals and emission targets for the future;
• Identifies opportunities and strategies for emissions reduction. 1 The 2010 GHG inventory report is available on the GCCOG website: https://www.gatewaycog.org/initiatives-andprojects/air-quality/climate-action-planning-framework.

3.2 GHG Inventory Results for 2015
Table 1 summarizes the City of Maywood’s 2015 Community GHG Inventory. On-road transportation was the prominent contributor in 2015, making up 50.4 percent of the City’s emissions. Total energy (electricity and natural gas) used by residential buildings was the second substantial contributor to the inventory (17.9 percent), followed by the total energy used by nonresidential (i.e., commercial, industrial, municipal) buildings (12.4 percent).

3.3 Emissions Trends and Forecast
In the calendar year 2015, total emissions generated by community activities in Maywood were 85,792 metric tons of CO2e (MTCO2e), compared to 88,721 in 2010.2 Table 2 summarizes the inventory results for these two years and indicates the contribution by sector. The results indicate that total emissions decreased by approximately 3.3 percent from 2010 to 2015. Additional key takeaways include:
• Despite a slight increase in vehicle miles traveled from 2010 to 2015, on-road transportation emissions dropped significantly (approximately 5.5 percent from 2010 to 2015). The decrease is largely attributable to cleaner, more fuel-efficient vehicles on the road in 2015 than in 2 Note that this is a slight revision from the 2010 inventory (88,447 MT CO2e) developed by the Gateway Cities COG CAP Framework project, reflecting updated modeling, emissions factors, and data sources that are consistent with those used by the 2015 inventory.

2010. On-road transportation remains the largest contributor to overall emissions at approximately 50.4 percent, similar to its 51.5 percent contribution in 2010. • Despite an approximate 13.1 percent increase in total building electricity use from 2010 to 2015, emissions associated with that use of electricity (residential + non-residential) dropped approximately 5.5 percent. Electricity use by buildings remains a significant contributor to overall emissions, at approximately 16.4 percent of the 2015 inventory, compared to 16.8 percent of the 2010 inventory.
• Emissions from all other sources were little changed in 2015 compared to 2010. This includes natural gas emissions, which in total (residential and non-residential) are the third biggest contributor to the 2010 and 2015 inventories, at approximately 13.7 percent and 13.9 percent, respectively.

3.3.1 Business as Usual Forecast
The business-as-usual (BAU) community GHG emissions forecast for the City of Maywood is based on the effect that local growth (population, jobs, and housing) is expected to have on community emissions after 2015 in the absence of GHG reduction programs. BAU forecasts are useful in climate action planning because they provide the basis against which GHG reduction programs can be quantified in terms of their ability to reduce emissions at key planning horizons (e.g., the City’s General Plan horizon).

Using socioeconomic growth forecasts provided by Fehr & Peers, BAU forecasts were developed for the years 2030 and 2045. As shown in Table 3, Figure 6, and Figure 7, the BAU forecasts of community GHG emissions are 85,073 MTCO2e, and 85,551 MTCO2e, respectively for 2030 and 2045. The results indicate that total emissions under BAU conditions would decrease slightly in 2030 and 2045, as compared to 2010.

It is important to note that the BAU forecast assumes no change to the vehicle efficiency standards, building energy standards (i.e., Title 24, Part 6), and grid electricity emission factors that were in place as of 2015. Since 2015, vehicles have become more fuel efficient, Title 24 building standards have become more stringent, and grid electricity has generally become less carbon intensive. Thus, the BAU forecast presented here represents a conservative estimate of future emissions. An adjustment to the BAU forecast that accounts for these factors is presented in the next section.
