Of the 27 buildings, 13 buildings would be dedicated to 83 tandem townhomes and 14 buildings would be dedicated to 108 row townhomes. The Project would comprise a total of 191 dwelling units. Each unit would include two garage spaces. The Project would provide 104 double-striped guest parking spaces. Additionally, the Project would provide public right of way improvements such as a 1,253 square foot of parkway and a 3,000 square foot improved sidewalk along Walnut Grove Avenue. The Project would provide 126,015 square foot of open space for residents, including 75,004 square foot of landscaping, 43,597 square foot of hardscape, 3,831 square foot of decomposed granite, 972 SF playground, 1,933 square foot pool, and 160 square foot spa. A dog park, bench seating, and picnic tables would be located in the northeast corner of the Project Site. On the southeast corner of the Project Site, the Project would include a bioretention basin and recreation center with a restroom facility, community pool, group spa, cabanas, gas barbeque grills, and a sundeck. A community garden with dwarf citrus trees would be located in the southwest corner of the Project Site. A central garden court with a shade structure, picnic tables, open lawn play area, and tot-lot with play equipment and rubber surfacing would be located between buildings 13, 14, 17, and 18. Project construction is anticipated to occur over one phase, lasting approximately 34 months, beginning as early as October 2026 and ending as early as August 2029. Project construction and architectural coating would occur over one phase. Construction would be consistent with the City of Rosemead Municipal Code (RMC) Chapter 8.36, including, without limitation, the City’s noise policies. Specifically, construction would be prohibited between the hours of 8 PM and 7 AM Monday through Saturday and prohibited on Sunday or any Federal holiday, in accordance with RMC Chapter 8.36.030, Exemptions. No nighttime construction activities are anticipated. Project Site preparation for the Project would require cutting and removal of approximately 22,457 tons of recycled concrete and 5,461 tons of recycled asphalt. Materials cut would remain on site and would not be hauled away. Approximately 7,500 cubic yards of import would be required. Environmental Setting Global climate change refers to changes in average climatic conditions on Earth as a whole, including temperature, wind patterns and precipitation. Global temperatures are moderated by naturally occurring atmospheric gases, including water vapor, carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as well as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). These “greenhouse” gases (GHGs) allow solar radiation (sunlight) into the Earth’s atmosphere but prevent radiative heat from escaping, thus warming the Earth’s atmosphere. GHGs are emitted by both natural processes and human activities. Concentrations of GHG have increased in the atmosphere since the industrial revolution. Human activities that generate GHG emissions include combustion of fossil fuels (CO2 and N2O); natural gas generated from landfills, fermentation of manure and cattle farming (CH4); and industrial processes such as nylon and nitric acid production (N2O). GHGs are global pollutants, unlike criteria air pollutants and toxic air contaminants, which are pollutants of regional and local concern. GHGs have varying global warming potential (GWP).

Environmental Setting Global climate change refers to changes in average climatic conditions on Earth as a whole, including temperature, wind patterns and precipitation. Global temperatures are moderated by naturally occurring atmospheric gases, including water vapor, carbon dioxide (CO;), methane (CHa), and nitrous oxide (N>0), as well as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SFe). These “greenhouse” gases (GHGs) allow solar radiation (sunlight) into the Earth’s atmosphere but prevent radiative heat from escaping, thus warming the Earth’s atmosphere. GHGs are emitted by both natural processes and human activities. Concentrations of GHG have increased in the atmosphere since the industrial revolution. Human activities that generate GHG emissions include combustion of fossil fuels (CO; and NO); natural gas generated from landfills, fermentation of manure and cattle farming (CHa); and industrial processes such as nylon and nitric acid production (NO). GHGs are global pollutants, unlike criteria air pollutants and toxic air contaminants, which are pollutants of regional and local concern. GHGs have varying global warming potential (GWP). The GWP kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 Page 5 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 is the potential of a gas or aerosol to trap heat in the atmosphere; it is the “cumulative radiative forcing effect of a gas over a specified time horizon resulting from the emission of a unit mass of gas relative to a reference gas.” The reference gas for GWP is CO2; therefore, CO2 has a GWP factor of 1. The other main GHGs that have been attributed to human activity include CH4, which has a GWP factor of 28, and N2O, which has a GWP factor of 265. When accounting for GHGs, all types of GHG emissions are expressed in terms of CO2 equivalents (CO2e) and are typically quantified in metric tons (MT) or million metric tons (MMT). Regulatory Setting Federal Energy Independence and Security Act of 2007 The Energy Independence and Security Act (EISA) of 2007, among other key measures, requires the following, which would aid in the reduction of national GHG emissions: • Increase the supply of alternative fuel sources by setting a mandatory Renewable Fuel Standard requiring fuel producers to use at least 36 billion gallons of biofuel in 2022. • Set a target of 35 miles per gallon (mpg) or the combined fleet of cars and light trucks by model year 2020 and direct the National Highway Traffic Safety Administration (NHTSA) to establish a fuel economy program for medium- and heavy-duty trucks and create a separate fuel economy standard for work trucks. • Prescribe or revise standards affecting regional efficiency for heating and cooling products and procedures for new or amended standards, energy conservation, energy efficiency labeling for consumer electronic products, residential boiler efficiency, electric motor efficiency, and home appliances. On April 9, 2025, President Trump signed an executive order calling for the sunset of various environmental regulations. The order affects pieces of several keystone energy and environmental legislation, including the Energy Independence and Security Act of 2007. United States Environmental Protection Agency Endangerment Finding The United States Environmental Protection Agency (U.S. EPA) authority to regulate GHG emissions stems from the United States Supreme Court decision in Massachusetts v. EPA (2007). The Supreme Court ruled that GHGs meet the definition of air pollutants under the existing Federal Clean Air Act (FCAA) and must be regulated if these gases could be reasonably anticipated to endanger public health or welfare. Responding to the Court’s ruling, the U.S. EPA finalized an endangerment finding in December 2009. Based on scientific evidence it found that six GHGs (CO2, CH4, N2O, HFCs, PFCs, and SF6) constitute a threat to public health and welfare. Thus, it is the Supreme Court’s interpretation of the existing FCAA and the U.S. EPA’s assessment of the scientific evidence that form the basis for the U.S. EPA’s regulatory actions. In response to President Trump’s “Unleashing American Energy” Executive Order, published on January 20, 2025, the U.S. EPA announced its intention to reconsider regulations and actions that rely Kimley»Horn Page is the potential of a gas or aerosol to trap heat in the atmosphere; it is the “cumulative radiative forcing effect of a gas over a specified time horizon resulting from the emission of a unit mass of gas relative to a reference gas.” The reference gas for GWP is CO;; therefore, CO; has a GWP factor of 1.

The March 12 announcement specifically targets the following: • Advanced Clean Trucks Plan, including: o Control of Air Pollution from New Motor Vehicles: Heavy-Duty Engine and Vehicle Standards o Multi-Pollutant Emissions Standards for Model Years 2027 and Later Light- and Medium-Duty Vehicles o Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles – Phase 3. • Corporate Average Fuel Economy (CAFE) Standards Federal Vehicle Standards In response to the United States Supreme Court ruling discussed above, Executive Order 13432 was issued in 2007 directing the U.S. EPA, the Department of Transportation, and the Department of Energy to establish regulations that reduce GHG emissions from motor vehicles, non-road vehicles, and non-road engines by 2008. In 2009, the NHTSA issued a final rule regulating fuel efficiency and GHG emissions from cars and light-duty trucks for model year 2011, and in 2010, the U.S. EPA and NHTSA issued a final rule regulating cars and light-duty trucks for model years 2012 through 2016. In 2010, an Executive Memorandum was issued directing the Department of Transportation, Department of Energy, U.S. EPA, and NHTSA to establish additional standards regarding fuel efficiency and GHG reduction, clean fuels, and advanced vehicle infrastructure. In response to this directive, the U.S. EPA and NHTSA proposed stringent, coordinated federal GHG and fuel economy standards for model years 2017 through 2025 light-duty vehicles. The proposed standard is projected to achieve 163 grams per mile of CO2 in model year 2025, on an average industry fleet-wide basis, which is equivalent to 54.5 mpg if this level were achieved solely through fuel efficiency. The final rule was adopted in 2012 for model years 2017 through 2021. On January 12, 2017, the U.S. EPA finalized its decision to maintain the current GHG emissions standards for model years 2022 through 2025 cars and light trucks. In addition to the regulations applicable to cars and light-duty trucks described above, in 2011, the U.S. EPA and NHTSA announced fuel economy and GHG standards for medium- and heavy-duty trucks for model years 2014 through 2018. The standards for CO2 emissions and fuel consumption are tailored to three main vehicle categories: combination tractors, heavy-duty pickup trucks and vans, and vocational vehicles. According to the U.S. EPA, this regulatory program will reduce GHG emissions and fuel consumption for the affected vehicles by six to 23 percent over the 2010 baselines. In August 2016, the U.S. EPA and NHTSA announced the adoption of the phase two program related to the fuel economy and GHG standards for medium- and heavy-duty trucks. The phase two program will apply to vehicles with model year 2018 through 2027 for certain trailers, and model years 2021 through 2027 for semi-trucks, large pickup trucks, vans, and all types and sizes of buses and work trucks. The final standards are expected to lower CO2 emissions by approximately 1.1 billion metric Kimley»Horn Pages on the 2009 Greenhouse Gas Endangerment Finding (Endangerment Finding) on March 12, 2025.

In 2018, the President and the U.S. EPA stated their intent to halt various federal regulatory activities to reduce GHG emissions, including the phase two program. California and other states have stated their intent to challenge federal actions that would delay or eliminate GHG reduction measures and have committed to cooperating with other countries to implement global climate change initiatives. On September 27, 2019, the U.S. EPA and the NHTSA published the “Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule Part One: One National Program.” (84 Fed. Reg. 51,310 (September 27, 2019.) The Part One Rule revokes California’s authority to set its own GHG emissions standards and set zero- emission vehicle (ZEV) mandates in California. On March 31, 2020, the U.S. EPA and NHTSA finalized rulemaking for SAFE Part Two which sets CO2 emissions standards and CAFE standards for passenger vehicles and light duty trucks, covering model years 2021 through 2026. The U.S. EPA repealed SAFE Rule Part One, effective January 28, 2022, and is reconsidering Part Two. In December 2021, the U.S. EPA finalized federal GHG emissions standards for passenger cars and light trucks for model years 2023 through 2026. These standards are the strongest vehicle emissions standards ever established for the light-duty vehicle sector and are based on an assessment of current and future technologies. The updated standards will result in avoiding more than 3 billion tons of GHG emissions through 20501 and are on track for the launch of U.S. EPA’s next phase of standards for model years 2027 and beyond. As of April 1, 2022, the CAFE standards require an industry-wide fleet average of approximately 49 mpg for passenger cars and light trucks in model year 2026. The new CAFE standards for model year 2024 through 2026 reduces fuel use by more than 200 billion gallons through 2050, as compared to continuing under the old standards.2 On June 7, 2024, the NHTSA announced the final rule for passenger cars and light trucks for model years 2027 through 2031, which strengthened previous emission standards and proposed an industry- wide fleet average of approximately 50.4 mpg in model year 2031. The new CAFE standards for model years 2027 through 2031 would reduce fuel use by 70 billion gallons through 2050.3 In response to President Trump’s “Unleashing American Energy” Executive Order, published on January 20, 2025, the U.S. EPA announced its intention to reconsider regulations and actions that rely on the Endangerment Finding on March 12, 2025. This includes the CAFE standards.

On March 31, 2020, the U.S. EPA and NHTSA finalized rulemaking for SAFE Part Two which sets CO, emissions standards and CAFE standards for passenger vehicles and light duty trucks, covering model years 2021 through 2026. The U.S. EPA repealed SAFE Rule Part One, effective January 28, 2022, and is reconsidering Part Two. In December 2021, the U.S. EPA finalized federal GHG emissions standards for passenger cars and light trucks for model years 2023 through 2026. These standards are the strongest vehicle emissions standards ever established for the light-duty vehicle sector and are based on an assessment of current and future technologies. The updated standards will result in avoiding more than 3 billion tons of GHG emissions through 2050? and are on track for the launch of U.S. EPA’s next phase of standards for model years 2027 and beyond. As of April 1, 2022, the CAFE standards require an industry-wide fleet average of approximately 49 mpg for passenger cars and light trucks in model year 2026. The new CAFE standards for model year 2024 through 2026 reduces fuel use by more than 200 billion gallons through 2050, as compared to continuing under the old standards.2 On June 7, 2024, the NHTSA announced the final rule for passenger cars and light trucks for model years 2027 through 2031, which strengthened previous emission standards and proposed an industry- wide fleet average of approximately 50.4 mpg in model year 2031. The new CAFE standards for model years 2027 through 2031 would reduce fuel use by 70 billion gallons through 2050.3 In response to President Trump’s “Unleashing American Energy” Executive Order, published on January 20, 2025, the U.S. EPA announced its intention to reconsider regulations and actions that rely on the Endangerment Finding on March 12, 2025. This includes the CAFE standards. On June 6, 2025, the NHTSA published an interpretive rule that establishes the NHTSA’s authority to revise the CAFE 1 United States Environmental Protection Agency, Final Rule to Revise Existing National GHG Emissions Standards for Passenger Cars and Light Trucks Through Model Year 2026, 2021, https://www.epa.gov/regulations-emissions-vehicles-and-engines/final-rule-revise- existing-national-ghg-emissions.

Therefore, implementation of these standards remains uncertain. State California Air Resources Board The California Air Resources Board (CARB) is responsible for the coordination and oversight of State and local air pollution control programs in California. Various statewide and local initiatives to reduce California’s contribution to GHG emissions have raised awareness about climate change and its potential for severe long-term adverse environmental, social, and economic effects. California is a significant emitter of CO2e in the world and produced 371.1 gross MMTCO2e in 2022.4 In the State, the transportation sector is the largest emitter of GHGs, followed by industrial operations such as manufacturing and oil and gas extraction. The State of California legislature has enacted a series of bills that constitute the most aggressive program to reduce GHGs of any state in the nation. Some legislation, such as the landmark Assembly Bill (AB) 32, California Global Warming Solutions Act of 2006, was specifically enacted to address GHG emissions. Other legislation, such as Title 24 Building Energy Efficiency Standards and Title 20 Appliance Energy Standards, were originally adopted for other purposes such as energy and water conservation, but also provide GHG reductions. Assembly Bill 32 AB 32, the California Global Warming Solutions Act of 2006, instructed CARB to develop and enforce regulations for the reporting and verification of statewide GHG emissions and established a State goal of reducing GHG emissions to 1990 levels by the year 2020. AB 32 additionally established a timeline for adopting a scoping plan for achieving GHG reductions in a technologically and economically feasible manner. The Scoping Plan was first approved by CARB in 2008 and is updated every five years. Climate Change Scoping Plan The Scoping Plan is a GHG emission reduction roadmap developed and updated by the CARB at least once every five years, as required by AB 32. It lays out the transformations needed across various sectors to reduce GHG emissions and reach the State’s climate targets. CARB published the Final 2022 Scoping Plan for Achieving Carbon Neutrality (2022 Scoping Plan) in November 2022, as the third update to the initial plan that was adopted in 2008. The initial 2008 Scoping Plan laid out a path to achieve the AB 32 target of returning to 1990 levels of GHG emissions by 2020, a reduction of approximately 15 percent below business as usual activities.5 The 2008 Scoping Plan included a mix of incentives, regulations, and carbon pricing, laying out the portfolio approach to addressing climate change and clearly making the case for using multiple tools to meet California’s GHG targets.

According to the 2022 Scoping Plan, the 2030 target is an interim but important stepping stone along the critical path to the broader goal of deep decarbonization by 2045. The relatively longer path assessed in the 2022 Scoping Plan incorporates, coordinates, and leverages many existing and ongoing efforts to reduce GHGs and air pollution, while identifying new clean technologies and energy. Given the focus on carbon neutrality, the 2022 Scoping Plan also includes discussion for the first time of the natural and working lands sectors as sources for both sequestration and carbon storage, and as sources of emissions as a result of wildfires.

Executive Order N-19-19 Governor Newsom signed Executive Order N-19-19 in September 2019 to direct state government to redouble its efforts to reduce GHG emissions and mitigate the impacts of climate change while building a sustainable, inclusive economy. This Executive Order instructs the Department of Finance to create a Climate Investment Framework that: • Includes a proactive strategy for the state’s pension funds that reflects the increased risks to the economy and physical environment due to climate change. • Provides a timeline and criteria to shift investments to companies and industry sectors with greater growth potential based on their focus of reducing carbon emissions and adapting to the impacts of climate change. • Aligns with the fiduciary responsibilities of the California Public Employees’ Retirement System, California State Teachers’ Retirement System, and the University of California Retirement Program. Executive Order N-19-19 directs the State Transportation Agency to leverage more than $5 billion in annual state transportation spending to help reverse the trend of increased fuel consumption and reduce GHG emissions associated with the transportation sector. It also calls on the Department of General Services to leverage its management and ownership of the state’s 19 million square feet in managed buildings, 51,000 vehicles, and other physical assets and goods to minimize state government’s carbon footprint. Finally, it tasks CARB with accelerating progress toward California’s goal of five million ZEV sales by 2030 by: • Developing new criteria for clean vehicle incentive programs to encourage manufacturers to produce clean, affordable cars. • Proposing new strategies to increase demand in the primary and secondary markets for ZEVs. • Considering strengthening existing regulations or adopting new ones to achieve the necessary GHG reductions from within the transportation sector.

Executive Order N-19-19 directs the State Transportation Agency to leverage more than $5 billion in annual state transportation spending to help reverse the trend of increased fuel consumption and reduce GHG emissions associated with the transportation sector. It also calls on the Department of General Services to leverage its management and ownership of the state’s 19 million square feet in managed buildings, 51,000 vehicles, and other physical assets and goods to minimize state government's carbon footprint. Finally, it tasks CARB with accelerating progress toward California's goal of five million ZEV sales by 2030 by: eo Developing new criteria for clean vehicle incentive programs to encourage manufacturers to produce clean, affordable cars. e Proposing new strategies to increase demand in the primary and secondary markets for ZEVs. eo Considering strengthening existing regulations or adopting new ones to achieve the necessary GHG reductions from within the transportation sector. kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 Page 13 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 Table 2: Climate Legislation and Executive Orders Enacted Since the 2017 Scoping Plan Legislation Summary The 2022 Scoping Plan modeling reflects efforts to accelerate ZEV deployment. AB 65: Coastal Protection: Climate Adaption: Project Prioritization: Natural Infrastructure: Local General Plans (Petrie-Norris, Chapter 347, Statutes of 2019) This bill requires the State Coastal Conservancy, when it allocates any funding appropriated pursuant to the California Drought, Water, Parks, Climate, Coastal Protection, and Outdoor Access For All Act of 2018, to prioritize projects that use natural infrastructure in coastal communities to help adapt to climate change. The bill requires the conservancy to provide information to the Office of Planning and Research on any projects funded pursuant to the above provision to be considered for inclusion into the clearinghouse for climate adaptation information. The bill authorizes the conservancy to provide technical assistance to coastal communities to better assist them with their projects that use natural infrastructure. Executive Order B-55-18 Governor Brown signed Executive Order B-55-18 in September 2018 to establish a statewide goal to achieve carbon neutrality as soon as possible, and no later than 2045, and to achieve and maintain net negative emissions thereafter. Policies and programs undertaken to achieve this goal shall: • Seek to improve air quality and support the health and economic resiliency of urban and rural communities, particularly low-income and disadvantaged communities. • Be implemented in a manner that supports climate adaptation and biodiversity, including protection of the state’s water supply, water quality, and native plants and animals. This Executive Order also calls for CARB to: • Develop a framework for implementation and accounting that tracks progress toward this goal. • Ensure future Scoping Plans identify and recommend measures to achieve the carbon neutrality goal. The 2022 Scoping Plan is designed to achieve carbon neutrality no later than 2045 and the modeling includes technology and fuel transitions to achieve that outcome.

California’s Legislature and state agencies will continue to collaborate to achieve the state’s climate, clean air, equity, and broader economic and environmental protection goals. It will be necessary to maintain and strengthen this collaborative effort, and to draw upon the assistance of the federal government, regional and local governments, tribes, communities, academic institutions, and the private sector to achieve the state’s near-term and longer-term emission reduction goals and a more equitable future for all Californians. The Scoping Plan acknowledges that the path forward is not dependent on one agency, one state, or even one country. However, the State can lead by engaging Californians and demonstrating how actions at the state, regional, and local levels of governments, as well as action at community and individual levels, can contribute to addressing the challenge. Aligning local jurisdiction action with State-level priorities to tackle climate change and the outcomes called for in the 2022 Scoping Plan are identified as critical to achieving the statutory targets for 2030 and 2045. The 2022 Scoping Plan discusses the role of local governments in meeting the State’s GHG reductions goals. Local governments have the primary authority to plan, zone, approve, and permit how and where land is developed to accommodate population growth, economic growth, and the changing needs of their jurisdictions. They also make critical decisions on how and when to deploy transportation infrastructure, and can choose to support transit, walking, bicycling, and neighborhoods that do not force people into cars. Local governments also have the option to adopt building ordinances that exceed statewide building code requirements and play a critical role in facilitating the rollout of ZEV infrastructure. As a result, local government decisions play a critical role in supporting state-level measures to contain the growth of GHG emissions associated with the transportation system and the built environment—the two largest GHG emissions sectors over which local governments have authority. Title 20 Appliance Efficiency Regulations The appliance efficiency regulations (California Code of Regulations [CCR] Title 20, Sections 1601- 1608) include standards for new appliances. Twenty-three categories of appliances are included in the scope of these regulations. These standards include minimum levels of operating efficiency, and other cost-effective measures, to promote the use of energy- and water-efficient appliances. Title 24 Building Energy Efficiency Standards California’s Energy Efficiency Standards for Residential and Nonresidential Buildings (CCR Title 24, Part 6) was first adopted in 1978 in response to a legislative mandate to reduce California’s energy consumption. The standards are updated periodically to allow consideration and possible incorporation of new energy efficient technologies and methods. Energy efficient buildings require less electricity; therefore, increased energy efficiency reduces fossil fuel consumption and decreases GHG emissions. In December 2024, the 2025 Energy Code was approved by the California Building Standards Commission for inclusion into the California Building Standards Code. The 2025 Energy Code encourages efficient electric heat pumps, establishes electric-ready requirements for new homes, expands solar photovoltaic and battery storage standards, strengthens ventilation standards, and Kimley»Horn page 15 and technical solutions to go further, faster.

Rather, CEQA Guidelines emphasize the lead agency’s discretion to determine the appropriate methodologies and thresholds of significance consistent with the manner in which other impact areas are handled in CEQA. CEQA Guidelines Section 15064.4 provides that a lead agency shall make a good-faith effort, based to the extent possible on scientific and factual data, to describe, calculate, or estimate the amount of GHG emissions resulting from a project. It also states that the lead agency shall have the discretion to determine, in the context of a particular project, whether to: (1) quantify GHG emissions resulting from a project; and/or (2) rely on a qualitative analysis or performance-based standards. Lead agencies should consider several factors when determining the significance of GHG emissions from a project: the extent to which the project may increase or reduce GHG emissions as compared to the existing environmental setting; whether a project exceeds a significance threshold that the lead agency determines applies to the project; and the extent to which the project complies with regulations or requirements adopted to implement a statewide, regional or local plan for the reduction or mitigation of GHG emissions. CEQA Guidelines Section 15064.4 does not establish a threshold of significance. Lead agencies have the discretion to establish significance thresholds for their respective jurisdictions, and in establishing those thresholds, a lead agency may appropriately look to thresholds developed by other public agencies, or suggested by other experts, such as the California Air Pollution Control Officers Association, as long as any threshold chosen is supported by substantial evidence (see CEQA Guidelines Section 15064.7(c)). The CEQA Guidelines also clarify that the effects of GHG emissions are cumulative and should be analyzed in the context of CEQA’s requirements for cumulative impact analysis (see CEQA Guidelines Section 15130(f)). The CEQA Guidelines were amended to specify that compliance with a GHG emissions reduction plan renders a cumulative impact insignificant. Per CEQA Guidelines Section 15064(h)(3), a project’s incremental contribution to a cumulative impact can be found not cumulatively considerable if the project would comply with an approved plan or mitigation program that provides specific requirements that would avoid or substantially lessen the cumulative problem within the geographic area of the project.11 To qualify, such plans or programs 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. CEQA Guidelines Section 15183.5(b) allows a lead agency to make a finding of less than significant for GHG emissions if a project complies with adopted programs and/or other regulatory schemes to reduce GHG emissions. The City has not adopted a numeric threshold for the analysis of GHG impacts. This analysis uses the SCAQMD proposed 3,000 MTCO2e threshold for new, non-industrial development as the significance criteria. Though not formally adopted by SCAQMD, the numeric target is supported by expert opinion and the evidence in the record of the proceedings of the SCAQMD GHG CEQA Significance Threshold 11 14 California Code of Regulations, Section 15064(h)(3). Kimley»Horn page 18 The Appendix G thresholds for GHG emissions do not prescribe specific methodologies for performing an assessment, do not establish specific thresholds of significance, and do not mandate specific mitigation measures. Rather, CEQA Guidelines emphasize the lead agency's discretion to determine the appropriate methodologies and thresholds of significance consistent with the manner in which other impact areas are handled in CEQA. CEQA Guidelines Section 15064.4 provides that a lead agency shall make a good-faith effort, based to the extent possible on scientific and factual data, to describe, calculate, or estimate the amount of GHG emissions resulting from a project. It also states that the lead agency shall have the discretion to determine, in the context of a particular project, whether to: (1) quantify GHG emissions resulting from a project; and/or (2) rely on a qualitative analysis or performance-based standards. Lead agencies should consider several factors when determining the significance of GHG emissions from a project: the extent to which the project may increase or reduce GHG emissions as compared to the existing environmental setting; whether a project exceeds a significance threshold that the lead agency determines applies to the project; and the extent to which the project complies with regulations or requirements adopted to implement a statewide, regional or local plan for the reduction or mitigation of GHG emissions. CEQA Guidelines Section 15064.4 does not establish a threshold of significance. Lead agencies have the discretion to establish significance thresholds for their respective jurisdictions, and in establishing those thresholds, a lead agency may appropriately look to thresholds developed by other public agencies, or suggested by other experts, such as the California Air Pollution Control Officers Association, as long as any threshold chosen is supported by substantial evidence (see CEQA Guidelines Section 15064.7(c)).

In addition, CEQA Guidelines Section 15064.4(b)(2) allows the City to determine a threshold of significance that applies to the Project, and accordingly the threshold of significance applied here is whether the Project complies with applicable plans, policies, regulations, and requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of GHG emissions. This analysis considers qualitative consistency with State GHG reduction goals as articulated in the 2022 Scoping Plan and SCAG 2024-2050 RTP/SCS. Methodology The Project’s construction and operational GHG emissions were calculated using the CARB-approved California Emissions Estimator Model (CalEEMod) version 2022.1. CalEEMod is a Statewide land use emissions computer model designed to quantify potential GHG emissions associated with construction and operations from a variety of land use projects. GHG impacts were assessed according to methodologies recommended by CARB and SCAQMD. Project construction of the on-site development and off-site improvements would generate emissions from off-road equipment usage and on-road vehicle travel associated with haul, delivery, and construction worker trips. Annual construction emissions are estimated by assuming construction occurs at the earliest feasible date (i.e., a conservative estimate of construction activities) and applying off-road, fugitive dust, and on-road emissions factors in CalEEMod. Project operations would result in emissions from mobile sources (motor vehicles from Project- generated vehicle trips), area sources (hearths, consumer products, architectural coatings, landscape maintenance equipment), electrical generation, natural gas combustion, water supply and wastewater treatment, solid waste generation, and water usage. The mobile source emissions were estimated in CalEEMod based on the Project vehicle trip generation from the Traffic Study prepared by Kimley-Horn.12 Other operational emissions were quantified in CalEEMod based on land use activity data. Greenhouse Gas Impacts Threshold (a) Would the project generate GHG emissions, either directly or indirectly, that could have a significant impact on the environment? Construction Emissions Project construction would result in direct GHG emissions from construction equipment and the transport of materials and construction workers to and from the Project Site. Construction-generated GHG emissions would be temporary and would cease with completion of construction. Project construction is anticipated to occur over approximately 34 months, beginning as early as October 2026 and ending as early as August 2029.

California Air Resource Board 2022 Scoping Plan The 2022 Scoping Plan sets a path to achieve targets for carbon neutrality and reduce anthropogenic GHG emissions by 85 percent below 1990 levels by 2045 in accordance with AB 1279. The 2022 Scoping Plan aims to achieve the AB 1279 targets primarily through ZE transportation (e.g., electrifying cars, buses, trains, and trucks) and decarbonizing the electricity and industrial sectors. The Project would be required to comply with applicable current and future regulatory requirements promulgated through the 2022 Scoping Plan. Statewide strategies to reduce GHG emissions in the latest 2022 Scoping Plan include implementing SB 100, which would achieve 100 percent clean electricity by 2045; achieving 100 percent ZEV in 2035 through Advanced Clean Cars II15; and implementing the Advanced Clean Fleets regulation to deploy ZEV buses and trucks.16 Additional transportation policies include the Potential Phased Advanced 15 On May 22, 2025, the United States Senate voted to revoke the waiver granted by the Biden administration for the Advanced Clean Cars II program.

The 2022 Scoping Plan would continue to implement SB 375. Project GHGs would be further reduced through the Cap-and-Trade Program carbon pricing and SB 905. SB 905 requires CARB to create the Carbon Capture, Removal, Utilization, and Storage Program to evaluate, demonstrate, and regulate carbon dioxide removal projects and technology. As shown in Table 4, approximately 93 percent of the Project’s emissions are from energy and mobile sources, which would be further reduced by the 2022 Scoping Plan actions described above. The City has no control over vehicle emissions (approximately 75 percent of the Project’s total emissions). However, these emissions would decline in the future due to Statewide measures, as well as cleaner technology and fleet turnover. Furthermore, the Project would not obstruct or interfere with efforts to increase ZEVs or State efforts to improve system efficiency. Compliance with applicable State standards (e.g., continuation of the Cap-and-Trade regulation; CARB’s Mobile Source Strategy, and Sustainable Freight Action Plan; Executive Order N-79-20; SB 100: renewable electricity portfolio improvements that require 60 percent renewable electricity by 2030 and 100 percent renewable by 2045, etc.) would ensure consistency with State and regional GHG reduction planning efforts. The Project would additionally comply with the Energy Code and CALGreen Code, which require energy conservation features in new construction (e.g., high-efficiency lighting, high-efficiency heating, ventilating, and air-conditioning systems, thermal insulation, double-glazed windows, water conserving plumbing fixtures). Conserving energy usage would indirectly regulate and reduce GHG emissions. It is also noted that the Project would not convert any Natural and Working Lands and/or decrease the State’s urban forest carbon stock, which are areas of emphasis in the 2022 Scoping Plan. Furthermore, the Project would develop residential land uses that would potentially reduce VMT and associated GHG emissions for some residents.17 Regarding the 2050 goals under Executive Order S-3-05, it is not possible at this time to quantify the emissions savings from future regulatory measures, as they have not yet been developed; nevertheless, it can be anticipated that Project operations would benefit from applicable measures enacted to meet State GHG reduction goals. Impacts would be less than significant, and no mitigation is required.

The Project would include a majority of the feasible operational measures listed in the 2022 Scoping Plan Appendix D as design features. Some of the recommended operational measures include requiring drought-tolerant landscaping and energy conserving appliances and fixtures. The 2022 Scoping Plan Appendix D states that project consistency with the Scoping Plan can be determined through consistency with a local Climate Action Plan that addresses the State’s largest sources of emissions and prioritize transportation electrification, VMT reduction, and building decarbonization. Project contributions to climate goals in relation to the largest sources of emissions are discussed further below: • Transportation Electrification. The 2022 Scoping Plan notes that to be clearly consistent with the State’s goals, projects should provide electric vehicle charging infrastructure that, at minimum, meets the most ambitious voluntary standard in the CALGreen Code. The Project would be consistent with the CALGreen Code. • VMT Reduction. The 2022 Scoping Plan includes strategies to increase access to public transit by increasing density of development near transit. The Project would increase residential density near transit options. The Project Site is located approximately 0.25-mile (1,342 feet) from the Los Angeles County Metropolitan Transportation Authority 287 bus stop and approximately 0.33-mile (1,772 feet) from the Montebello Transit 20 San Gabriel bus line. • Building Decarbonization. Building decarbonization refers to emissions reduction strategies including maximizing energy efficiency, use of low- and zero-carbon electricity, demand flexibility, energy storage, use of very low- or no-GWP refrigerants, and eliminating fuel combustion by electrifying appliances and equipment.18 The townhouses would be all-electric except for the pool and spa which would utilize natural gas for heating. The Project would include project features aimed at increasing transportation electrification, reducing VMT, and maximizing building decarbonization. Thus, the Project would not impede the State’s progress towards carbon neutrality by 2045 under the 2022 Scoping Plan. As such, impacts would be less than significant, and no mitigation is required. SCAG RTP/SCS Consistency Under SB 375, SCAG’s 2024-2050 RTP/SCS establishes GHG emissions goals to reduce GHG emissions in the region by eight percent from 2005 levels by 2020 and by 19 percent by 2035. The RTP/SCS is a long-range vision plan that balances future mobility and housing needs with economic, environmental, and public health goals.

The Project Site is located approximately 0.25-mile (1,342 feet) from the Los Angeles County Metropolitan Transportation Authority 287 bus stop and approximately 0.33-mile (1,772 feet) from the Montebello Transit 20 San Gabriel bus line. e Building Decarbonization. Building decarbonization refers to emissions reduction strategies including maximizing energy efficiency, use of low- and zero-carbon electricity, demand flexibility, energy storage, use of very low- or no-GWP refrigerants, and eliminating fuel combustion by electrifying appliances and equipment.® The townhouses would be all-electric except for the pool and spa which would utilize natural gas for heating. The Project would include project features aimed at increasing transportation electrification, reducing VMT, and maximizing building decarbonization. Thus, the Project would not impede the State’s progress towards carbon neutrality by 2045 under the 2022 Scoping Plan. As such, impacts would be less than significant, and no mitigation is required. SCAG RTP/SCS Consistency Under SB 375, SCAG’s 2024-2050 RTP/SCS establishes GHG emissions goals to reduce GHG emissions in the region by eight percent from 2005 levels by 2020 and by 19 percent by 2035. The RTP/SCS is a long-range vision plan that balances future mobility and housing needs with economic, environmental, and public health goals. The 2024-2050 RTP/SCS is supported by a combination of transportation and land use strategies that help the region achieve state GHG emissions reduction goals and FCAA requirements, increased 18 California Air Resources Board, 2022 Scoping Plan for Achieving Carbon Neutrality, Appendix F — Building Decarbonization, 2022. kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 Page 24 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 housing production, improved equity and resilience, the preservation of natural lands, improvement of public health, increased transportation safety, support for the region’s vital goods movement industries and more efficient use of resources.

The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi. Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi. Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi. 6.2.
