There are currently two addendums to the 2009 Arboretum Specific Plan that evaluated individual Specific Plan amendments, one from 2016 and one from 2024. The currently proposed Resort Village Amendment (project) is a new amendment to the Arboretum Specific Plan that would convert a portion of the Resort Village planning area from residential to commercial use to allow for a small shopping center. The amendment would maintain the 3,532 dwelling units previously approved for buildout of the Specific Plan by transferring the residential development potential of the subject property to other portions of the Specific Plan planning area in Fontana, California. This analysis was prepared using methods and assumptions recommended in the air quality impact assessment guidelines of the South Coast Air Quality Management District (SCAQMD) in its CEQA Air Quality Handbook (1993) and associated updates. This analysis includes an assessment of criteria pollutant emissions, an assessment of carbon monoxide (CO) hot-spot impacts, and an assessment of the project’s GHG emissions. Project Location The project site, within the Arboretum Specific Plan area, is located north of Casa Grande Avenue, east of Citrus Avenue, west of Sierra Avenue, and south of Grapeland Street in the northern portion of Fontana, in southwestern San Bernardino County, California. The Resort Village planning area is a square-shaped, undeveloped property that consists of 18 parcels (Assessor’s Parcel Numbers [APNs] 1 City of Fontana. 2009. Arboretum Specific Plan.

Figure 1 shows the regional and project location (all figures are provided in Attachment A). Approved Project The Arboretum Specific Plan (referenced as the “approved project” throughout this document) is a master-planned development comprising four primary Planning Area villages (The Meadows, The Gardens, The Resort, and The Arboretum) on 531.3 gross acres within which a total of 3,532 residential units, 8.8 acres of commercial activity center, 46.4 acres of school, and 42.4 acres of parks/recreation were previously approved. Local street uses are proposed, and a network of pedestrian trails and bike paths occur throughout the site. Infrastructure to support the site includes water, sewer, electric, gas, telephone, cable television, drainage, and roadway extensions. In the approved project, the Resort Village planning area covers 159.6 acres on the northeastern quadrant of the overall Specific Plan area. As approved, this village would feature a mix of single- family lots, medium and high-density residential units, an elementary school, and a commercial activity center area. The commercial activity center would be located at the southeastern corner at the Sierra Avenue and Duncan Canyon Road intersection. Scattered parks would be provided within the village, connected by streets and walking trails. The high-density units would be clustered in the central and southeastern sections. Lower density units would be located around the elementary school site to be located in the southwestern corner of the village. Residential density would be 11.2 units per gross acre. The proposed project would update the Resort Village planning area development, as further described in the following section. Proposed Project Description The proposed project would convert approximately 9.3 acres of the Resort Village planning area from R-MF (Residential Multi-Family, 8.0-16.0 dwelling units per acre) to C-1 (Community Commercial) and would develop the 9.3-acre property with approximately 73,558 square feet of commercial uses. The 8.8-acre community activity center, currently designated C-1 with an Activity Center overlay, would remain as previously approved. As proposed, the village would continue to feature a mix of single-family lots, medium and high-density residential units, parks, and an elementary school, but would add community commercial areas. As previously approved, one 8.8- acre commercial area would be located at the southeastern corner of the planning area, at the Sierra Avenue and Duncan Canyon Road intersection, and as currently proposed the second 9.3-acre commercial area would be located along the eastern border of the site, northwest of the current intersection of Sierra Avenue and Terra Vista Drive. Scattered parks would be provided within the village, connected by streets and walking trails. The high-density units would be clustered with parks, commercial, and school uses, and lower-density units would be clustered in the northeastern section. Residential density would be reduced to 10.5 units per gross acre. Table A shows the changes from the approved project within the Resort Village planning area, which include an increase from 8.8 acres of commercial uses to 18.1 acres of commercial uses, a decrease in acreage of residential uses with density ranges between 8 and 16 du/ac, an increase in residential uses with density ranges between 16 and 20 du/ac, and a decrease in Collector Street acreage. There would be no change in the proposed acreage of residential uses with density ranges between 6 and 8 du/ac. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» Table A: The Resort Village Proposed Land Use Changes PA Land Use Acreage Target Density PA Land Use Acreage Target Density R-1 RM-F 10.1 8-12 10.0 R-1 RM-F 7.7 16-20 17.0 R-2 RM-F 9.5 8-12 10.0 R-2 RM-F 9.1 16-20 19.0 R-3 RM-F 11.7 10-15 12.0 R-3 RM-F 5.8 10-15 10.0 R-4 RM-F 8.3 16-20 20.0 R-4 RM-F 8.0 16-20 19.0 R-5 RM-F 5.5 16-20 18.0 R-5 RM-F 9.0 8-12 12.0 R-6 RM-F 5.6 6-8 7.0 R-6 RM-F 7.5 16-20 20.0 R-7 RM-F 6.6 6-8 7.0 R-7 RM-F 9.0 16-20 17.0 R-8 RM-F 8.1 14-16 16.0 R-8 RM-F 8.7 16-20 18.0 R-9 RM-F 9.0 14-16 14.0 R-9 RM-F 12.2 5-10 7.0 R-10 RM-F 7.7 16-20 18.0 R-10 RM-F 5.1 8-12 10.0 R-11 RM-F 7.5 16-20 19.0 R-11 RM-F 9.6 10-15 14.0 R-12 RM-F 6.0 16-20 20.0 R-12 RM-F 4.4 16-20 20.0 R-13 RM-F 6.0 16-20 20.0 NAP RM-F 3.8 8-12 10.0 - - - - C-1 Community Commercial 9.3 - - - - - - C-2 Community Commercial 8.8 - - Elementary School 12.1 - - Elementary School 12.1 - - Neighborhood Park 2.6 - - Neighborhood Park 2.8 - - Community Parks 5.9 - - Community Parks 5.7 - - Activity Center 8.8 - - - - - - Perimeter Streets 14.0 - - Perimeter Streets 14.0 - - Collector Streets 14.6 - - Collector Streets 7.01 - - Source: Lewis Management Corporation Notes: 1 Per Section 8.2 of the Specific Plan, up to 10 percent of the R-MF 3.0-8.0 units in a particular residential planning area may be transferred to another R-MF 3.0-8.0 planning area, provided the maximum unit count for the Specific Plan as a whole does not exceed 3,532 units.

Additionally, the proposed project would reduce community parks acreage from 5.9 to 5.7 acres, while increasing neighborhood parks from 2.6 to 2.8 acres. Collector streets within the Resort Village planning area would be reconfigured and reduced in acreage from 14.6 acres to 7.01 acres under the proposed project. Primary gated entries would remain on Duncan Canyon Road and Cypress Avenue, and secondary gates would remain on Grapeland Street and Sierra Avenue. Construction of the proposed project is anticipated to commence in March 2026 and be completed in late 2032. Construction activities for the proposed project would include site preparation, grading, building construction, paving, and architectural coating activities. Construction hours would conform to City of Fontana (City) standards and be limited to 7:00 a.m. to 6:00 p.m. Monday through Friday. According to the approved project, grading is expected to be balanced on-site, and no import or export of materials would be required. Figure 2 shows the Resort Village land use plan. Existing Land Uses in the Project Area For the purposes of this analysis, sensitive receptors are areas of the population that have an increased sensitivity to air pollution or environmental contaminants. Sensitive receptor locations include residences, schools, daycare centers, hospitals, parks, and similar uses that are sensitive to air quality. Impacts on sensitive receptors are of particular concern because those receptors are the population most vulnerable to the effects of air pollution. Existing land uses near the project area include residences, a school, and undeveloped land. The existing residences are south and east of the project site, with new residential construction occurring to the south of the project site. The Kordyak Elementary School is east of the project site, across Sierra Avenue. Undeveloped land is immediately north and west. As the project is planned to be built in four phases, with the latter three phases including new residential uses, these new sensitive receptors would potentially be impacted by construction of latter phases. ENVIRONMENTAL SETTING Air Quality Background Air quality is primarily a function of local climate, local sources of air pollution, and regional pollution transport. The amount of a given pollutant in the atmosphere is determined by the amount of the pollutant released and the atmosphere’s ability to transport and dilute the pollutant. The major determinants of transport and dilution are wind, atmospheric stability, terrain and, for photochemical pollutants, sunshine. A region’s topographic features have a direct correlation with air pollution flow and therefore are used to determine the boundary of air basins. The proposed project is in Riverside County, and is within the jurisdiction of SCAQMD, which regulates air quality in the South Coast Air Basin (Basin). The Basin comprises approximately 10,000 square miles and covers all of Orange County and the urban parts of Los Angeles, Riverside, and San Bernardino Counties. The Basin is on a coastal plain 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» with connecting broad valleys and low hills to the east. Regionally, the Basin is bounded by the Pacific Ocean to the southwest and high mountains to the east, forming the inland perimeter. Both State and federal governments have established health-based Ambient Air Quality Standards for six criteria air pollutants: CO, ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), lead (Pb), and suspended particulate matter. In addition, the State has set standards for sulfates, hydrogen sulfide, vinyl chloride and visibility-reducing particles. These standards are designed to protect the health and welfare of the populace with a reasonable margin of safety. Two criteria pollutants, O3 and NO2, are considered regional pollutants because they (or their precursors) affect air quality on a regional scale. Pollutants such as CO, SO2, and Pb are considered local pollutants that tend to accumulate in the air locally. Air quality monitoring stations are located throughout the nation and are maintained by the local air districts and State air quality regulating agencies. Data collected at permanent monitoring stations are used by the United State Environmental Protection Agency (USEPA) to identify regions as “attainment” or “nonattainment” depending on whether the regions meet the requirements stated in the applicable National Ambient Air Quality Standards (NAAQS). Nonattainment areas are imposed with additional restrictions as required by the USEPA. In addition, different classifications of attainment (e.g., marginal, moderate, serious, severe, and extreme) are used to classify each air basin in the State on a pollutant-by-pollutant basis. The classifications are used as a foundation to create air quality management strategies to improve air quality and to comply with the NAAQS. As shown in Table B, the Basin is designated as nonattainment by federal standards for O3 and particulate matter less than 2.5 microns in diameter (PM2.5) and nonattainment by State standards for O3, particulate matter less than 10 microns in diameter (PM10), and PM2.5.

The reduction of peak concentrations represents progress in improving public health; however, the Basin still exceeds the State standard for 1-hour and 8-hour O3 levels. The USEPA lowered the 1997 0.80 parts per million (ppm) national 8-hour ozone standard to 0.75 ppm in 2008 and then to 0.70 ppm on October 1, 2015. The Basin is classified as nonattainment for the 1-hour and 8-hour ozone standards at the State and federal level. During the 2020–2022 period, the Fontana Monitoring Station located at 14360 Arrow Boulevard (the closest monitoring station to the project site) recorded the following exceedances of the State and federal 1-hour and 8-hour O3 standards:1 • The federal 8-hour ozone standard had 81 exceedances in 2021, 68 exceedances in 2022, and 74 exceedances in 2023. • The State 8-hour ozone standard had 81 exceedances in 2021, 68 exceedances in 2022, and 74 exceedances in 2023. • The federal 1-hour ozone standard had 1 exceedance in each of 2021 and 2022 and 2 exceedances in 2023. • The State 1-hour ozone standard had 44 exceedances in each of 2021 and 2022 and 56 exceedances in 2023. National and State standards have also been established for PM2.5 over 24-hour and yearly averaging periods. PM2.5, because of the small size of individual particles, can be especially harmful to human health. PM2.5 is emitted by common combustion sources such as cars, trucks, buses, and power plants, in addition to ground-disturbing activities. On December 17, 2006, the USEPA strengthened the 24-hour PM2.5 NAAQS from 65 micrograms per cubic meter (µg/m3) to 35 µg/m3, and the Basin was subsequently designated “moderate” nonattainment for 2006 24-hour PM2.5 NAAQS on December 14, 2009. The Basin is also considered a nonattainment area for the PM2.5 standard at the State level. During the 2020–2022 time period, the Fontana Monitoring Station recorded the following exceedances of the federal 24-hour PM2.5 standards. The State 24-hour PM2.5 standards had no exceedances in the 3-year period: • The federal 24-hour PM2.5 standard had 2 exceedances in 2021, 1 exceedance in each of 2022 and 2023. The Basin is classified as a PM10 nonattainment area at the State level and was redesignated from serious nonattainment to attainment of the federal PM10 standard on July 26, 2013. Because the Basin was redesignated from nonattainment to attainment, a PM10 maintenance plan was adopted in 2013 and is required to be updated every 10 years.

The federal 24-hour PM10 standard had no exceedances in the 3-year period: • The federal 24-hour PM10 standard had no exceedances in 2021, 2022, or 2023. • The State 24-hour PM10 standard had 3 exceedances in 2021, 6 exceedances in 2022, and 8 exceedances in 2023. All areas of the Basin have continued to remain below the federal CO standards (35 ppm 1-hour and 9 ppm 8-hour) since 2003. The EPA redesignated the Basin to attainment of the federal CO standards, effective June 11, 2017. The Basin is also well below the State CO standards (20 ppm 1-hour CO and 9 ppm 8-hour CO). Greenhouse Gas Background GHGs are present in the atmosphere naturally, are released by natural sources, or form from secondary reactions taking place in the atmosphere. Over the last 200 years, humans have caused substantial quantities of GHGs to be released into the atmosphere. These extra emissions are increasing GHG concentrations in the atmosphere and enhancing the natural greenhouse effect, which is believed to be causing global warming. Although manmade GHGs include naturally occurring GHGs such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), some gases like hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), nitrogen trifluoride (NF3), and sulfur hexafluoride (SF6) are completely new to the atmosphere. Certain gases, such as water vapor, are short-lived in the atmosphere. Others remain in the atmosphere for significant periods of time, contributing to climate change in the long term. Water vapor is excluded from the list of GHGs above because it is short-lived in the atmosphere and its atmospheric concentrations are largely determined by natural processes, such as oceanic evaporation. These gases vary considerably in terms of Global Warming Potential (GWP), which is a concept developed to compare the ability of each GHG to trap heat in the atmosphere relative to another gas. The GWP is based on several factors, including the relative effectiveness of a gas to absorb infrared radiation and length of time that the gas remains in the atmosphere (“atmospheric lifetime”). The GWP of each gas is measured relative to CO2, the most abundant GHG; the definition of GWP for a particular GHG is the ratio of heat trapped by one unit mass of the GHG to the ratio of heat trapped by one unit mass of CO2 over a specified time period. GHG emissions are typically measured in terms of pounds or tons of “CO2 equivalents” (CO2e). REGULATORY SETTING This section provides regulatory background information for air quality and GHGs. Air Quality Applicable federal, State, regional, and local air quality regulations are discussed below. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» Federal Regulations The 1970 federal Clean Air Act (CAA) authorized the establishment of national health-based air quality standards and set deadlines for their attainment. The CAA Amendments of 1990 changed deadlines for attaining national standards as well as the remedial actions required for areas of the nation that exceed the standards. Under the CAA, State and local agencies in areas that exceed the national standards are required to develop State Implementation Plans to demonstrate how they will achieve the national standards by specified dates. State Regulations In 1988, the California Clean Air Act (CCAA) required that all air districts in the State endeavor to achieve and maintain California Ambient Air Quality Standards (CAAQS) for CO, O3, SO2, and NO2 by the earliest practical date. The CCAA provides districts with the authority to regulate indirect sources and mandates that air quality districts focus particular attention on reducing emissions from transportation and area-wide emission sources. Each nonattainment district is required to adopt a plan to achieve a 5 percent annual reduction, averaged over consecutive 3-year periods, in district- wide emissions of each nonattainment pollutant or its precursors. A Clean Air Plan shows how a district would reduce emissions to achieve air quality standards. Generally, the State standards for these pollutants are more stringent than the national standards. The California Air Resources Board (CARB) is the State’s “clean air agency.” CARB’s goals are to attain and maintain healthy air quality, protect the public from exposure to toxic air contaminants, and oversee compliance with air pollution rules and regulations. Regional Regulations The SCAQMD is the agency principally responsible for comprehensive air pollution control in the Basin. To that end, the SCAQMD, a regional agency, works directly with SCAG, CTCs, and local governments and cooperates actively with State and federal government agencies. The SCAQMD develops air quality-related rules and regulations, establishes permitting requirements, inspects emissions sources, and provides regulatory enforcement through such measures as educational programs or fines, when necessary. Regional Air Quality Management Plan. SCAQMD and SCAG are responsible for formulating and implementing the Air Quality Management Plan (AQMP) for the Basin. The main purpose of an AQMP is to bring the area into compliance with federal and State air quality standards. SCAQMD prepares a new AQMP every 3 years, updating the previous plan and a 20-year horizon. The latest plan is the 2022 AQMP, adopted December 2, 2022.1 On October 1, 2015, the EPA strengthened the NAAQS for ground-level O3, lowering the primary and secondary O3 standard levels to 70 parts per billion (ppb). The Basin is classified as an “extreme” nonattainment area for 1 South Coast Air Quality Management District (SCAQMD). 2022. 2022 Air Quality Management Plan. December.

The 2022 AQMP was developed to address the requirements for meeting this standard. SCAQMD adopts rules and regulations to implement portions of the AQMP. SCAQMD Guidance Documents. Although SCAQMD is responsible for regional air quality planning efforts, it does not have the authority to directly regulate the air quality issues associated with new development projects within the Basin, such as the proposed project. Instead, SCAQMD published the CEQA Air Quality Handbook 1 to assist lead agencies, as well as consultants, project proponents, and other interested parties, in evaluating potential air quality impacts of projects proposed in the Basin. The CEQA Air Quality Handbook provides standards, methodologies, and procedures for conducting air quality analyses in Environmental Impact Reports (EIRs). SCAQMD is currently in the process of replacing the CEQA Air Quality Handbook with the Air Quality Analysis Guidance Handbook.2 To assist the CEQA practitioner in conducting an air quality analysis in the interim while the replacement Air Quality Analysis Guidance Handbook is being prepared, supplemental guidance/ information is provided on the SCAQMD website. This guidance includes: (1) on-road vehicle emission factors, (2) background CO concentrations, (3) localized significance thresholds (LSTs), (4) mitigation measures and control efficiencies, (5) mobile-source toxics analysis, (6) off-road mobile- source emission factors, (7) PM2.5 significance thresholds and calculation methodology, and (8) updated SCAQMD Air Quality Significance Thresholds. SCAQMD also recommends using approved models to calculate emissions from land use projects, such as the California Emissions Estimator Model (CalEEMod). These recommendations were followed in the preparation of this analysis. SCAQMD Rules. The proposed project would be required to comply with regional rules that assist in reducing short-term air pollutant emissions. SCAQMD Rule 403 requires that fugitive dust be controlled with best available control measures so the presence of such dust does not remain visible in the atmosphere beyond the property line of the emissions source. In addition, SCAQMD Rule 403 requires implementation of dust suppression techniques to prevent fugitive dust from creating a nuisance off site. SCAQMD Rule 1113 limits the volatile organic compound (VOC) content of architectural coatings. Applicable dust suppression techniques from SCAQMD Rule 403 and low VOC content in paints under SCAQMD Rule 1113 are summarized below. Implementation of these dust suppression techniques can reduce the fugitive dust generation (and thus the PM10 component). Compliance with these rules would reduce impacts on nearby sensitive receptors.

South Coast Air Quality Management District Rule 1113 Measures. SCAQMD Rule 1113 governs the sale, use, and manufacture of architectural coating and limits the VOC content in paints and paint solvents. This rule regulates the VOC content of paints available during construction and operation of the proposed project. Therefore, all paints and solvents used during construction and operation of the proposed project must comply with SCAQMD Rule 1113. Local Regulations City of Fontana General Plan Update 2015-2035. The City of Fontana addresses air quality and GHG emissions in Chapter 12, Sustainability and Resilience, of the General Plan.1 The Sustainability and Resilience Chapter includes goals and policies that work to pursue sustainability and resilience by making resource-efficient choices to conserve water, energy, and materials, improve air quality, and adjust to changing conditions. The following policies are applicable to the proposed project: • Create a sustainable Fontana program that promotes green practices in government and in the community. • Incorporate goals into the City Code for resource efficiency in municipal facilities and operations. • Continue organizational and operational improvements to maximize energy and resource efficiency and reduce waste. • Promote renewable energy programs for government, Fontana businesses, and Fontana residences. Arboretum Specific Plan. As identified above, the project site is within the Arboretum Specific Plan area. The standard conditions and measures from The Arboretum Specific Plan EIR are listed below. All are applicable to the proposed project and would be implemented to reduce and avoid potential impacts related to air quality and GHGs.

Greenhouse Gas Emissions This section describes regulations related to global climate change at the federal, State, and local levels. Federal Regulations The United States has historically had a voluntary approach to reducing GHG emissions. However, on April 2, 2007, the United States Supreme Court ruled that the USEPA has the authority to regulate CO2 emissions under the CAA. Although there currently are no adopted federal regulations for the control or reduction of GHG emissions, the USEPA commenced several actions in 2009 to implement a regulatory approach to global climate change, including the 2009 USEPA final rule for mandatory reporting of GHGs from large GHG emission sources in the United States. Additionally, the USEPA Administrator signed an endangerment finding action in 2009 under the CAA, finding that seven GHGs (CO2, CH4, N2O, HFCs, NF3, PFCs, and SF6) constitute a threat to public health and welfare, and that the combined emissions from motor vehicles cause and contribute to global climate change, leading to national GHG emission standards. State Regulations CARB is the lead agency for implementing climate change regulations in the State. Since its formation, CARB has worked with the public, the business sector, and local governments to find solutions to California’s air pollution problems. Key efforts by the State are described below. Assembly Bill 32 (2006), California Global Warming Solutions Act. California’s major initiative for reducing GHG emissions is Assembly Bill (AB) 32, passed by the State legislature on August 31, 2006. This effort set a GHG emission reduction target to reduce GHG emissions to 1990 levels by 2020. CARB has established the level of GHG emissions in 1990 at 427 million metric tons (MMT) of CO2e. The emissions target of 427 MMT requires the reduction of 169 MMT from the State’s projected business-as-usual 2020 emissions of 596 MMT. AB 32 requires CARB to prepare a Scoping Plan that outlines the main State strategies for meeting the 2020 deadline and to reduce GHGs that contribute to global climate change. CARB approved the Scoping Plan on December 11, 2008. It contains the main strategies California will implement to achieve the reduction of approximately 169 MMT of CO2e, or approximately 30 percent, from the State’s projected 2020 emission level of 596 MMT of CO2e under a business-as-usual scenario (this is a reduction of 42 MMT of CO2e, or almost 10 percent from 2002–2004 average emissions). The Scoping Plan also includes CARB recommended GHG reductions for each emissions sector of the State’s GHG inventory. The Scoping Plan calls for the largest reductions in GHG emissions to be achieved by implementing the following measures and standards: 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» • Improved emissions standards for light-duty vehicles (estimated reduction of 31.7 MMT CO2e); • The Low-Carbon Fuel Standard (15.0 MMT CO2e); • Energy efficiency measures in buildings and appliances and the widespread development of combined heat and power systems (26.3 MMT CO2e); and • A renewable portfolio standard for electricity production (21.3 MMT CO2e). The Scoping Plan identifies 18 emission reduction measures that address cap-and-trade programs, vehicle gas standards, energy efficiency, low carbon fuel standards, renewable energy, regional transportation-related GHG targets, vehicle efficiency measures, goods movement, solar roof programs, industrial emissions, high-speed rail, green building strategies, recycling, sustainable forests, water, and air. The measures would result in a total reduction of 174 MMT of CO2e by 2020. The Scoping Plan identifies 18 emission reduction measures that address cap-and-trade programs, vehicle gas standards, energy efficiency, low carbon fuel standards, renewable energy, regional transportation-related GHG targets, vehicle efficiency measures, goods movement, solar roof programs, industrial emissions, high-speed rail, green building strategies, recycling, sustainable forests, water, and air. The measures would result in a total reduction of 174 MMT CO2e by 2020. On August 24, 2011, the CARB unanimously approved both the new supplemental assessment and reapproved its Scoping Plan, which provides the overall roadmap and rule measures to carry out AB 32. The CARB approved the First Update to the Climate Change Scoping Plan on May 22, 2014. The CARB released a second update to the Scoping Plan, the 2017 Scoping Plan,1 to reflect the 2030 target set by EO B-30-15 and codified by Senate Bill (SB) 32. Most recently, the 2022 Scoping Plan2 was approved in December 2022 and assesses progress toward the statutory 2030 target, while laying out a path to achieving carbon neutrality no later than 2045. The 2022 Scoping Plan Update focuses on outcomes needed to achieve carbon neutrality by assessing paths for clean technology, energy deployment, natural and working lands, and others, and is designed to meet the State’s long- term climate objectives and support a range of economic, environmental, energy security, environmental justice, and public health priorities. Assembly Bill 1279 (2022), California Climate Crisis Act. Approved by Governor Newsom on September 16, 2022, AB 1279 would declare the policy of the State both to achieve net zero GHG emissions as soon as possible, but no later than 2045, and achieve and maintain net negative GHG emissions thereafter. AB 1279 would ensure that by 2045, Statewide anthropogenic GHG emissions are reduced to at least 85 percent below the 1990 levels. In addition, AB 1279 would require the State board to work with relevant State agencies to ensure that updates to the Scoping Plan identify 1 California Air Resources Board (CARB). 2017.

Senate Bill 375 (2008). Signed into law on October 1, 2008, SB 375 supplements GHG reductions from new vehicle technology and fuel standards with reductions from more efficient land use patterns and improved transportation. Under the law, CARB-approved GHG reduction targets in February 2011 for California’s 18 federally designated regional planning bodies, known as Metropolitan Planning Organizations (MPOs). CARB may update the targets every 4 years and must update them every 8 years. MPOs, in turn, must demonstrate how their plans, policies and transportation investments meet the targets set by CARB through Sustainable Community Strategies (SCS). The SCSs are included with the Regional Transportation Plan, a report required by State law. However, if an MPO finds that its SCS will not meet the GHG reduction targets, it may prepare an Alternative Planning Strategy. The Alternative Planning Strategy identifies the impediments to achieving the targets. Executive Order B-30-15 (2015). Governor Jerry Brown signed EO B-30-15 on April 29, 2015, which added the immediate target of: • GHG emissions should be reduced to 40 percent below 1990 levels by 2030. All State agencies with jurisdiction over sources of GHG emissions were directed to implement measures to achieve reductions of GHG emissions to meet the 2030 and 2050 targets. CARB was directed to update the AB 32 Scoping Plan to reflect the 2030 target, and, therefore, is moving forward with the update process. The mid-term target is critical to help frame the suite of policy measures, regulations, planning efforts, and investments in clean technologies and infrastructure needed to continue reducing emissions. Senate Bill 350 (2015) Clean Energy and Pollution Reduction Act. SB 350, signed by Governor Jerry Brown on October 7, 2015, updates and enhances AB 32 by introducing the following set of objectives in clean energy, clean air, and pollution reduction for 2030: • Raise California’s renewable portfolio standard from 33 percent to 50 percent; and • Increase energy efficiency in buildings by 50 percent by the year 2030. The 50 percent renewable energy standard will be implemented by the California Public Utilities Commission (CPUC) for the private utilities and by the California Energy Commission (CEC) for municipal utilities. Each utility must submit a procurement plan showing it will purchase clean energy to displace other nonrenewable resources. The 50 percent increase in energy efficiency in buildings must be achieved through the use of existing energy efficiency retrofit funding and regulatory tools already available to State energy agencies under existing law. The addition made by this legislation requires State energy agencies to plan for and implement those programs in a manner that achieves the energy efficiency target. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» Senate Bill 32, California Global Warming Solutions Act of 2016, and Assembly Bill 197. In summer 2016 the Legislature passed, and the Governor signed, SB 32 and AB 197. SB 32 affirms the importance of addressing climate change by codifying into statute the GHG emissions reductions target of at least 40 percent below 1990 levels by 2030 contained in Governor Brown’s April 2015 EO B-30-15. SB 32 builds on AB 32 and keeps us on the path toward achieving the State’s 2050 objective of reducing emissions to 80 percent below 1990 levels, consistent with an Intergovernmental Panel on Climate Change (IPCC) analysis of the emission trajectory that would stabilize atmospheric GHG concentrations at 450 ppm CO2e and reduce the likelihood of catastrophic impacts from climate change. The companion bill to SB 32, AB 197, provides additional direction to CARB related to the adoption of strategies to reduce GHG emissions. Additional direction in AB 197 meant to provide easier public access to air emissions data that are collected by CARB was posted in December 2016. Senate Bill 100. On September 10, 2018, Governor Brown signed SB 100, which raises California’s renewable portfolio standard requirements to 60 percent by 2030, with interim targets, and 100 percent by 2045. The bill also establishes a State policy that eligible renewable energy resources and zero-carbon resources supply 100 percent of all retail sales of electricity to California end-use customers and 100 percent of electricity procured to serve all State agencies by December 31, 2045. Under the bill, the State cannot increase carbon emissions elsewhere in the Western grid or allow resource shuffling to achieve the 100 percent carbon-free electricity target. Executive Order B-55-18. EO B-55-18, signed September 10, 2018, sets a goal “to achieve carbon neutrality as soon as possible, and no later than 2045, and achieve and maintain net negative emissions thereafter.” EO B-55-18 directs CARB to work with relevant State agencies to ensure future Scoping Plans identify and recommend measures to achieve the carbon neutrality goal. The goal of carbon neutrality by 2045 is in addition to other statewide goals, meaning not only should emissions be reduced to 80 percent below 1990 levels by 2050, but that, by no later than 2045, the remaining emissions be offset by equivalent net removals of CO2e from the atmosphere, including through sequestration in forests, soils, and other natural landscapes. Title 24, Building Efficiencies Standards and the California Green Building Standards Code. In November 2008, the California Building Standards Commission established the California Green Building Standards Code (CALGreen Code) (California Code of Regulations, Title 24, Part 11), which sets performance standards for residential and nonresidential development to reduce environmental impacts and to encourage sustainable construction practices. The CALGreen Code addresses energy efficiency, water conservation, material conservation, planning and design, and overall environmental quality. The CALGreen Code was most recently updated in 2022 to include new mandatory measures for residential and nonresidential uses. These measures took effect January 1, 2023. Regional Regulations Southern California Association of Governments. The Southern California Association of Governments (SCAG) is a regional council consisting of the following six counties: Imperial, Los 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» Angeles, Orange, Riverside, San Bernardino, and Ventura. In total, the SCAG region encompasses 191 cities and over 38,000 square miles within Southern California. SCAG is the MPO serving the region under federal law and serves as the Joint Powers Authority, the Regional Transportation Planning Agency, and the Council of Governments under State law. As the Regional Transportation Planning Agency, SCAG prepares long-range transportation plans for the Southern California region, including the Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) and the 2008 Regional Comprehensive Plan (RCP). On April 4, 2024, the Regional Council of SCAG adopted Connect SoCal A Plan for Navigating to a Brighter Future, also known as the 2024–2050 Regional Transportation Plan/Sustainable Communities Strategy (2024–2050 RTP/SCS)1. The 2024–2050 RTP/SCS is a long-range visioning plan that balances future mobility and housing needs with economic, environmental, and public health goals. The 2024–2050 RTP/SCS embodies a collective vision for the region’s future and is developed with input from local governments, county transportation commissions (CTCs), tribal governments, nonprofit organizations, businesses, and local stakeholders within Imperial, Los Angeles, Orange, Riverside, San Bernardino, and Ventura counties. South Coast Air Quality Management District. In 2008, SCAQMD formed a Working Group to identify GHG emissions thresholds for land use projects that could be used by local lead agencies in the Basin. The Working Group developed several different options that are contained in the SCAQMD 2008 draft guidance document titled Interim CEQA GHG Significance Threshold for Stationary Sources, Rules and Plans (2008) that could be applied by lead agencies. On September 28, 2010, SCAQMD Working Group Meeting No.15 provided further guidance, including a tiered approach for evaluating GHG emissions for development projects where SCAQMD is not the lead agency. SCAQMD has not presented a finalized version of these thresholds to the governing board. SCAQMD identifies the emissions level for which a project would not be expected to substantially conflict with any State legislation adopted to reduce statewide GHG emissions. As such, the utilization of a service population represents the rates of emissions needed to achieve a fair share of the State’s mandated emissions reductions. Overall, SCAQMD identifies a GHG efficiency level that, when applied statewide or to a defined geographic area, would meet the 2020 and post-2020 emission targets as required by AB 32 and SB 32. If projects are able to achieve targeted rates of emissions per the service population, the State would be able to accommodate expected population growth and achieve economic development objectives while also abiding by AB 32’s emissions target and future post-2020 targets. The SCAQMD has established a flow chart for evaluating GHG significance and indicates that when a project is exempt from CEQA, no further analysis is required. 1 Southern California Association of Governments (SCAG). 2024.

METHODOLOGY Construction Emissions Construction activities can generate a substantial amount of air pollution. Construction activities are considered temporary; however, short-term impacts can contribute to exceedances of air quality standards. Construction activities include site preparation, earthmoving, and general construction. The emissions generated from these common construction activities include fugitive dust from soil disturbance, fuel combustion from mobile heavy-duty, diesel- and gasoline-powered equipment, portable auxiliary equipment, and worker commute trips. The California Emissions Estimator Model version 2022.1 (CalEEMod) computer program was used to calculate emissions from on-site construction equipment and emissions from worker and vehicle trips to the site. Construction of the proposed project is anticipated to begin in early 2026 and end in late 2032. This analysis assumes that the proposed project would comply with the 2009 EIR Mitigation Measure 4.5.1 for dust control (see the Mitigation Measures section). Grading and building activities would involve the use of standard earthmoving equipment such as large excavators, cranes, and other related equipment. The Arboretum Specific Plan EIR Mitigation Measure 4.5.3a specifies that all construction equipment having more than 100 horsepower shall meet or exceed the EPA Tier 3 standards. Therefore, equipment having 100 horsepower or more was adjusted to meet Tier 3 standards. The rest of the equipment was assumed to meet Tier 2 standards. The 2009 EIR Mitigation Measure 4.5.3b specifies sub-measures to reduce ROG emissions. CalEEMod does not have provision for the first two 4.5.3b sub-measures, the third sub- measure was included. The proposed project would be assumed to be balanced, thus no soil import or export would be required. All other construction details are not yet known; therefore, default assumptions (e.g., construction worker and truck trips and fleet activities) from CalEEMod were used. Operational Emissions This air quality analysis includes estimating emissions associated with long-term operation of the project. Indirect emissions of criteria pollutants with regional impacts would be emitted by project- generated vehicle trips. In addition, localized air quality impacts (i.e., higher carbon monoxide 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» concentrations or “hot-spots”) near intersections or roadway segments in the project vicinity would also potentially occur due to project-generated vehicle trips. Consistent with SCAQMD guidance for estimating emissions associated with land use development projects, the CalEEMod computer program was used to calculate the long-term operational emissions associated with the project. As previously discussed in the Project Location and Description section, the proposed project would include the construction of single family and multifamily residential, retail uses and an elementary school. Full buildout of the proposed project was assumed to occur in 2032. Since the analysis of the approved project was prepared, CalEEMod version 2022.1 was approved and serves as the most up-to-date version of CalEEMod. As such, CalEEMod version 2022.1 was used to quantify the criteria pollutant emissions associated with operation of the approved project to provide a consistent comparison of changes between the approved project and the proposed project. The proposed project analysis was conducted using land use codes Single Family Housing, Apartments Low Rise, Supermarket, Strip Mall, Fast Food Restaurant with Drive Thru, City Park, Other Asphalt Surfaces, and Elementary School. Similarly, the approved project analysis was conducted using land use codes Single Family Housing, Apartments Low Rise, Strip Mall, City Park, Other Asphalt Surfaces and Elementary School. The approved project analysis assumes an operational year of 2026. To provide a consistent comparison of changes between the approved project and the proposed project, the trip rates used for the proposed project are consistent with the trip rates used for the approved project analysis, which uses the 7th edition of the Institute of Transportation Engineer (ITE) rates. When project-specific data were not available, default assumptions from CalEEMod were used to estimate project emissions. Greenhouse Gas Emissions GHG emissions associated with the project would occur over the short-term from construction activities, consisting primarily of emissions from equipment exhaust. There would also be long-term GHG emissions associated with project-related vehicular trips. Recognizing that the field of global climate change analysis is rapidly evolving, the approaches advocated most recently indicate that, for determining a project’s contribution to GHG emissions, lead agencies should calculate, or estimate, emissions from vehicular traffic, energy consumption, water conveyance and treatment, waste generation, construction activities, and any other significant source of emissions within the project area. The CalEEMod results were used to quantify GHG emissions generated by the project. THRESHOLDS OF SIGNIFICANCE The State CEQA Guidelines indicate that a project would normally have a significant adverse air quality impact if project-generated pollutant emissions would do any of the following: • Conflict with or obstruct implementation of the applicable air quality plan; • Result in a cumulatively considerable net increase of any criteria pollutant for which the project is nonattainment under applicable federal or State ambient air quality standards; • Expose sensitive receptors to substantial pollutant concentrations; or 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» • Result in other emissions (such as those leading to odors) affecting a substantial number of people. Certain air districts (e.g., SCAQMD) have created guidelines and requirements to conduct air quality analysis. The SCAQMD’s current guidelines, the CEQA Air Quality Handbook 1 with associated updates, were followed in this assessment of air quality impacts for the proposed project. Local Microscale Concentration Standards The significance of localized project impacts under CEQA depends on whether ambient CO levels in the vicinity of the project are above or below State and federal CO standards. Because ambient CO levels are below the standards throughout the Basin, a project would be considered to have a significant CO impact if project emissions result in an exceedance of one or more of the 1-hour or 8-hour standards. The following are applicable local emission concentration standards for CO: • California State 1-hour CO standard of 20 ppm; and • California State 8-hour CO standard of 9 ppm. Regional Emissions Thresholds SCAQMD has established daily emission thresholds for construction and operation of proposed projects in the Basin. The emission thresholds were established based on the attainment status of the Basin with regard to air quality standards for specific criteria pollutants. Because the concentration standards were set at a level that protects public health with an adequate margin of safety, these emission thresholds are regarded as conservative and would overstate an individual project’s contribution to health risks.

These thresholds, which the SCAQMD developed and that apply throughout the Basin, apply as both project and cumulative thresholds. If a project exceeds these standards, it is considered to have a project-specific and cumulative impact. Localized Impacts Analysis SCAQMD published its Final Localized Significance Threshold Methodology in July 2008, recommending that all air quality analyses include an assessment of air quality impacts to nearby sensitive receptors.1 This guidance was used to analyze potential localized air quality impacts associated with construction of the proposed project. Localized significance thresholds (LSTs) are developed based on the size or total area of the emission source, the ambient air quality in the source receptor area, and the distance to a sensitive receptors. Sensitive receptors include residences, schools, hospitals, and similar uses that are sensitive to adverse air quality. LSTs are based on the ambient concentrations of that pollutant within the project Source Receptor Area (SRA) and the distance to the nearest sensitive receptor. For the proposed project, the appropriate SRA for the LST is the Central San Bernardino Valley area (SRA 34). SCAQMD provides LST screening tables for 25-, 50-, 100-, 200-, and 500-meter source-receptor distances. As identified above, the closest existing sensitive receptors to the project site include single-family homes located to the east across Sierra Avenue at approximately 145 feet from the site boundary. As the project is planned to be built in four phases, with the latter three phases including new residential uses, the new sensitive receptors would potentially be impacted by construction of latter phases. By design, SCAQMD specifies that the minimum source-receptor distance to be considered in LST analyses is approximately 80 feet. An LST analysis was completed to show the construction and operational impacts at a distance of 25 meters (82 feet) to the nearest sensitive receptors. Based on the anticipated construction equipment, it is assumed that the maximum daily disturbed acreage for the proposed project would be 5 acres or less. Table D lists the emissions thresholds that apply during project construction and operation.

A project would normally have a significant effect on the environment if it would do either of the following: • Generate GHG emissions, either directly or indirectly, that may have a significant impact on the environment • Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs State CEQA Guidelines Section 15064(b) provides that the “determination of whether a project may have a significant effect on the environment calls for careful judgment on the part of the public agency involved, based to the extent possible on scientific and factual data,” and further states that an “ironclad definition of significant effect is not always possible because the significance of an activity may vary with the setting.” Currently, there is no Statewide GHG emissions threshold that has been used to determine the potential GHG emissions impacts of a project. Threshold methodology and thresholds are currently developed and revised by air districts in California. To provide guidance to local lead agencies on determining significance for GHG emissions in their CEQA documents, the SCAQMD convened a GHG CEQA Significance Threshold Working Group (Working Group).1 The Working Group has identified a tiered approach for evaluating GHG emissions for development projects where SCAQMD is not the lead agency: • Tier 1. If a project is exempt from CEQA, project-level and cumulative GHG emissions are less than significant. • Tier 2. If the project complies with a GHG emissions reduction plan or mitigation program that avoids or substantially reduces GHG emissions in the project’s geographic area (i.e., city or county), project-level and cumulative GHG emissions are less than significant. • Tier 3. If GHG emissions are less than the screening-level threshold, project-level and cumulative GHG emissions are less than significant. • For projects that are not exempt or where no qualifying GHG reduction plans are directly applicable, SCAQMD requires an assessment of GHG emissions. SCAQMD, under Option 1, is 1 South Coast Air Quality Management District (SCAQMD). Greenhouse Gases (GHG) CEQA Significance Thresholds.

This bright-line threshold is based on a review of the Office of Planning and Research (OPR) database of CEQA projects. Based on their review of 711 CEQA projects, 90 percent of CEQA projects would exceed the bright-line thresholds identified above. Therefore, projects that do not exceed the bright-line threshold would have a nominal and therefore less than cumulatively considerable impact on GHG emissions. • Tier 4. If emissions exceed the numerical screening threshold, a more detailed review of the project’s GHG emissions is warranted. The SCAQMD has proposed an efficiency target for projects that exceed the bright-line threshold. The current recommended approach is per-capita efficiency targets. The SCAQMD is not recommending use of a percentage emissions reduction target. Instead, the SCAQMD proposes proposed a 2020 efficiency target of 4.8 MT CO2e/year per service population for project-level analyses and 6.6 MT CO2e/year per service population for plan-level projects (e.g., program-level projects such as General Plans). For the purpose of this analysis, the proposed project will be compared to the threshold of 3,000 MT CO2e/year for all land use types. The project is also evaluated for compliance with the 2022 Scoping Plan and SCAG’s RTP/SCS. IMPACT ANALYSIS This section identifies potential air quality and GHG impacts associated with implementation of the proposed project. Air Quality Impacts Air pollutant emissions associated with the project would occur over the short term from construction activities and over the long term from project-related vehicular trips and due to energy consumption (e.g., electricity and natural gas usage) by the proposed land uses. Consistency with Applicable Air Quality Plans A consistency determination plays an essential role in local agency project review by linking local planning and unique individual projects to the air quality plans. A consistency determination fulfills the CEQA goal of fully informing local agency decision-makers of the environmental costs of the project under consideration at a stage early enough to ensure that air quality concerns are addressed. Only new or amended General Plan elements, Specific Plans, and significantly unique projects need to undergo a consistency review due to the air quality plan strategy being based on projections from local General Plans. The approved project is included in the Arboretum Specific Plan. The 2009 EIR for the Arboretum Specific Plan analyzed the approved project for consistency with the applicable Clean Air Plan and determined that the approved project was consistent with the SCAQMD 2007 Air Quality 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» Management Plan, and that impacts related to consistency with applicable air quality plans would be less than significant with no significant adverse impacts expected. The proposed project would change the land use designations originally analyzed under the approved project. The primary change is within the Resort Village planning area and consists of updating the land use zoning designation of a 9.25-acre parcel from residential to commercial. Additionally, residential land use designations are revised to absorb the dwelling units initially attributed to the 9.25-acre parcel and accommodate the same maximum total dwelling unit count per the current Specific Plan. On November 13, 2018, the City of Fontana adopted their General Plan Update 2015 – 2035 1 which was last updated July 2023. The 2021 Amended Arboretum Specific Plan demonstrated that the approved project is consistent with the Fontana General Plan Update 2015- 2035. Fontana General Plan Amendment No. GPA 23-000002 would update the General Plan land use designations included as part of the proposed project. The development density proposed on the site is different than what is allowed under the land use designations for the site. Both the approved project and the proposed project would increase residential development on the site and decrease commercial and light industrial development over those planned under the Fontana General Plan. Thus, neither are consistent with projections used in the 2007 AQMP. However, neither the approved project or the proposed project would exceed population and employment projections for the City. Both the approved project and the proposed project would also meet the demand for housing in the area and would provide schools, parks, goods, services, and jobs in proximity to housing. Future development on the site would be required to comply with applicable regulations of the SCAQMD regarding fugitive dust control, pollutant reductions, architectural coatings, toxic emissions, and other stationary equipment controls. Thus, it would comply with the regulations that have been developed to help meet air quality objectives for the region. The adopted AQMP contains a number of land use measures and goals that would benefit regional air quality. These include intensification of land uses near points of multiple transportation system access, mixed land uses to encourage non-vehicular mobility between homes, jobs and goods/services, and economic revitalization of depressed and blighted urban core areas. The proposed project meets these objectives through the development of residential uses, with on-site schools and parks and a commercial activity center. The City of Fontana promotes development that provides revenue for needed infrastructure; that provides commercial uses to serve residential neighborhoods and the community as a whole; and that provides employment opportunities to City residents. The proposed project would provide both housing and employment opportunities for the City’s residents. 1 City of Fontana, General Plan Update 2015 – 2035.

The creation of job opportunities at the project site and the provision of goods and services to serve the residential uses within the project and adjacent to the site would result in a reduction in vehicle trips and VMT. Both the approved project and the proposed project include development of the elementary school and combined elementary and middle school at the site that would reduce off-site travel by students and their parents/guardians. Both would provide on-site trails, bikeways and pedestrian walkways to encourage the use of alternatives to the automobile. Thus, both the approved project and the proposed project are consistent with air quality planning objectives and therefore are consistent with job and housing goals for the region. Also, a secondary consistency criterion from SCAQMD relates to violations of localized significance thresholds (LST). As discussed below, neither the approved project nor the proposed project would lead to violations of LSTs for the Western San Bernardino Valley. No significant adverse impacts were identified in the 2009 EIR nor are expected for the proposed project. Therefore, the proposed project would not result in new or worsening impacts than those identified in the 2009 EIR. Criteria Pollutant Analysis The South Coast Air Basin is currently designated as nonattainment for the federal and State standards for O3 and PM2.5. In addition, the Basin is in nonattainment for the PM10 standard. The Basin’s nonattainment status is attributed to the region’s development history. Past, present, and future development projects contribute to the region’s adverse air quality impacts on a cumulative basis. By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size to, by itself, result in nonattainment of an ambient air quality standard. Instead, a project’s individual emissions contribute to existing cumulatively significant adverse air quality impacts. If a project’s contribution to the cumulative impact is considerable, then the project’s impact on air quality would be considered significant. In developing thresholds of significance for air pollutants, SCAQMD considered the emissions levels for which a project’s individual emissions would be cumulatively considerable. If a project exceeds the identified significance thresholds, its emissions would be cumulatively considerable, resulting in significant adverse air quality impacts to the region’s existing air quality conditions. Therefore, additional analysis to assess cumulative impacts is not necessary. The following analysis assesses the potential project-level air quality impacts associated with construction and operation of the proposed project. Construction Emissions. The 2009 EIR identified under Impact 4.5.3 that construction activities associated with the proposed project would exceed SCAQMD thresholds for ROG (VOCs), NOx, CO, PM10 and PM2.5 and would result in a significant and unavoidable impact, even with implementation of Mitigation Measures 4.5.1, 4.5.2, 4.5.3a, 4.5.3.b, and 4.5.3c. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» During construction, short-term degradation of air quality may occur due to the release of particulate matter emissions (i.e., fugitive dust) generated by demolition, grading, building construction, paving, and other activities. Emissions from construction equipment are also anticipated and would include CO, nitrogen oxides (NOx), VOCs, directly emitted PM2.5 or PM10, and toxic air contaminants such as diesel exhaust particulate matter. Project construction activities would include grading, site preparation, building construction, architectural coating, and paving activities. Construction-related effects on air quality from the proposed project would be greatest during the site preparation phase due to the disturbance of soils. If not properly controlled, these activities would temporarily generate particulate emissions. Sources of fugitive dust would include disturbed soils at the construction site. Unless properly controlled, vehicles leaving the site would deposit dirt and mud on local streets, which could be an additional source of airborne dust after it dries. PM10 emissions would vary from day to day, depending on the nature and magnitude of construction activity and local weather conditions. PM10 emissions would depend on soil moisture, silt content of soil, wind speed, and amount of operating equipment. Larger dust particles would settle near the source, whereas fine particles would be dispersed over greater distances from the construction site. Water or other soil stabilizers can be used to control dust, resulting in emission reductions of 50 percent or more. SCAQMD has established Rule 403: Fugitive Dust, which would require the applicant to implement measures that would reduce the amount of particulate matter generated during the construction period. The Rule 403 measures that were incorporated in this analysis include: • Water active sites at least twice daily (locations where grading is to occur shall be thoroughly watered prior to earthmoving). • Cover all trucks hauling dirt, sand, soil, or other loose materials, or maintain at least 2 feet (0.6 meter) of freeboard (vertical space between the top of the load and the top of the trailer) in accordance with the requirements of California Vehicle Code Section 23114. • Reduce traffic speeds on all unpaved roads to 15 miles per hour or less. In addition to dust-related PM10 emissions, heavy trucks and construction equipment powered by gasoline and diesel engines would generate CO, sulfur oxides (SOx), NOx, VOCs, and some soot particulate (PM2.5 and PM10) in exhaust emissions. If construction activities were to increase traffic congestion in the area, CO and other emissions from traffic would increase slightly while those vehicles idle in traffic. These emissions would be temporary in nature and limited to the immediate area surrounding the construction site. Construction emissions were estimated for each phase of the project using CalEEMod and summarized in Table E. Emissions shown include all applicable EIR Mitigation Measures (described in the Mitigation Measures section). Attachment B provides CalEEMod output sheets. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» As noted above, the 2009 EIR found that construction activities associated with the approved project would exceed SCAQMD thresholds for VOCs, NOx, CO, PM10 and PM2.5 and would result in a significant and unavoidable impact, even with implementation of all feasible mitigation measures.

Therefore, construction of the proposed project would not result in any new air quality impacts not identified in the Arboretum Specific Plan EIR with implementation of Mitigation Measures 4.5.1, 4.5.2, 4.5.3a, 4.5.3.b, and 4.5.3c, and would result in potentially lower emissions than those estimated for the approved project. Therefore, the proposed project would not result in new or worsening impacts than those identified in the 2009 EIR. Operational Air Quality Impacts. Impact 4.5.4 of the 2009 EIR identified that vehicle emissions associated with the proposed project would exceed SCAQMD thresholds for ROG (VOCs), NOx, CO, and PM10, resulting in a significant and unavoidable impact, even with implementation of Mitigation Measures 4.5.4 and 4.5.5. Long-term air pollutant emissions associated with operation of the proposed project include emissions from area, energy, and mobile sources. Area-source emissions include architectural coatings, consumer products, and landscaping. Energy-source emissions result from activities in buildings that use natural gas. Mobile-source emissions are from vehicle trips associated with operation of the project. Area-source emissions consist of direct sources of air emissions at the project site, including architectural coatings, consumer products, and use of landscape maintenance equipment. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» PM10 emissions result from running exhaust, tire and brake wear, and the entrainment of dust into the atmosphere from vehicles traveling on paved roadways. Entrainment of PM10 occurs when vehicle tires pulverize small rocks and pavement, and the vehicle wakes generate airborne dust. The contribution of tire and brake wear is small compared to the other particulate matter emissions processes. Gasoline-powered engines have small rates of particulate matter emissions compared with diesel-powered vehicles. Energy-source emissions result from activities in buildings that use natural gas. The quantity of emissions is the product of usage intensity (i.e., the amount of natural gas) and the emissions factor of the fuel source. The primary sources of energy demand for the proposed project would include building mechanical systems such as water and space heating. Greater building or appliance efficiency reduces the amount of energy for a given activity and thus lowers the resultant emissions. Long-term operational emissions associated with the proposed project were calculated using CalEEMod. Table F provides the proposed project’s estimated operational emissions. Table F also shows the comparison to the approved project operational emissions. Attachment B provides CalEEMod output sheets.

Daily emissions of SOx and PM2.5 would not be expected to exceed applicable thresholds during the operational phases of the project. Comparing these emissions to the Resort Village portion of the 2009 EIR, at full project buildout, NOX and CO would be less than those estimated to occur under the approved project However, the proposed project would slightly increase emissions of VOCs, PM10, and PM2.5. In all cases where the proposed project daily emissions would be more than the estimated emissions expected to result from the operation of the Resort Village portion of the approved project, those emissions increases would be minimal as demonstrated by being less than the applicable SCAQMD thresholds. As shown in Table F, the mobile source emissions for the proposed project continue to be the vast majority of the total project emissions. Implementation of Mitigation Measures 4.5.4 and 4.5.5 would serve to reduce emissions associated with the proposed project. However, there are no measures that are feasible to reduce emissions for the proposed project below the applicable significance thresholds. Therefore, this impact would be significant and unavoidable. The 2009 EIR identified a significant and unavoidable impact related to operational emissions due to exceedances of established SCAQMD thresholds for criteria air pollutant emissions of VOC, NOx, CO, PM10, and PM2.5. Although there would be a slight increase in some emission categories, the increase would not be substantial. Therefore, operation of the proposed project would not result in any new or worsening air quality impacts not previously identified in the 2009 EIR. Long-Term Microscale (CO Hot Spot) Analysis. Vehicular trips associated with the proposed project would contribute to congestion at intersections and along roadway segments in the vicinity of the proposed project site. Localized air quality impacts would occur when emissions from vehicular traffic increase as a result of the proposed project. The primary mobile-source pollutant of local concern is CO, a direct function of vehicle idling time and, thus, of traffic flow conditions. CO transport is extremely limited; under normal meteorological conditions, it disperses rapidly with distance from the source. However, under certain extreme meteorological conditions, CO concentrations near a congested roadway or intersection may reach unhealthful levels, affecting local sensitive receptors (e.g., residents, schoolchildren, the elderly, and hospital patients). The 2009 EIR conducted a CO screening analysis at intersections near the project site, concluding that there would not be any CO Hot Spots from traffic from the entire Arboretum Specific Plan. As the CO impacts from the traffic from the proposed project would be a subset of the full Arboretum Specific Plan EIR CO screening analysis and the lack of traffic impacts at any intersections, project- related vehicles are not expected to result in CO concentrations exceeding the State or federal CO standards. No CO hot spots would occur, and the proposed project would not result in any project- related impacts on CO concentrations. Therefore, the proposed project would not result in any new or worsening impacts not identified in the 2009 EIR. Health Risk on Nearby Sensitive Receptors Sensitive receptors are defined as people who have an increased sensitivity to air pollution or environmental contaminants. Sensitive receptor locations include schools, parks and playgrounds, 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» daycare centers, nursing homes, hospitals, and residential dwelling units. As discussed above, the closest sensitive receptors during construction include the new residential land uses that are part of the project. The LST analysis was completed to show the construction impacts at the SCAQMD- recommended minimum distance of 25 meters (80 feet) to a sensitive receptor. By design, the localized impacts analysis only includes on-site sources, the CalEEMod output lists all emissions by location. Table G shows the results of the LST analysis for construction. As shown, the onsite construction emissions would all be less than their respective LST thresholds, meaning that the concentrations of the pollutants would not exceed their respective AAQS, which are set at levels that protect human health. Thus, the health risks to all sensitive receptors from construction would be less than thresholds. Table G: Project Localized Construction Emissions Source Pollutant Emissions (lbs/day) NOX CO PM10 PM2.5 Proposed Project Localized Significance Threshold 270 1,746 14 8 Significant? No No No No Note: Source Receptor Area 34, based on a 5-acre construction disturbance daily area, at a distance of 80 feet from the project lbs/day = pounds per day 2.5 PM10 = particulate matter less than 10 microns in size The 2009 EIR found that, because the prevailing wind direction would result in few residences being downwind of the project site, no LST analysis was required and therefore neither a construction nor an operational LST analysis was completed. Due to subsequent buildout of the area surrounding the proposed project area, this analysis includes an LST analysis for both construction and operations. For the construction LST analysis, as illustrated in Table G, the proposed project would not result in an exceedance of the SCAQMD recommended LSTs. . This impact would be less than significant, and there would be no new or worsening impacts related to localized construction emissions from the proposed project than were analyzed in the 2009 EIR. Similar to the construction LST analysis, for the proposed project, the emissions that would occur onsite during operations were estimated and compared to the LSTs to determine the health risk levels to sensitive receptors from operations. To estimate the portion of regional emissions shown in Table F (the maximum operational emissions occurs when the entire project is complete) that would occur onsite, it was assumed that all area and energy source emissions would occur on site. However, given that the average vehicle trip length included in the CalEEMod analysis is 12 miles, it was estimated that 1 percent of the project-related mobile emissions would occur on site. The 2009 EIR did not distinguish which operational emissions would occur onsite, so similar to the technique used for the proposed project’s operational emissions (assuming one percent of the total vehicle emissions would occur onsite), Table H shows the approved project’s estimated onsite 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» operational emissions, as included in the 2009 EIR, as well as the proposed project estimated onsite operational emissions as compared to the LST thresholds established by SCAQMD.

Note: Source Receptor Area 34, based on a 5-acre operational daily area, distance of 80 feet from project boundary. CO = carbon monoxide lbs/day = pounds per day 2.5 PM10 = particulate matter less than 10 microns in size As shown, the estimated onsite operational emissions would all be less than applicable LST thresholds, meaning that the concentrations of the pollutants would not exceed the respective AAQS, which are set at levels that protect human health. Thus, the health risks to all sensitive receptors from operations would be less than thresholds. The 2009 EIR did not include an operational LST analysis, but based on the emissions shown in Table H the Resort Village portion of the approved project onsite operational emissions would be less than the LSTs, thus the proposed project would not result in a new significant LST impact from project operations. Therefore, there would not be a new or worsening impact related to localized operational emissions from the proposed project than those analyzed in the 2009 EIR. As detailed in Tables G and H, the emissions levels indicate that the project would not exceed SCAQMD LSTs during project construction or operation. The project’s peak operational on-site NOx emissions are approximately 31.2 pounds per day (lbs/day). Due to the small size of the proposed project in relation to the overall Basin, the level of emissions is not sufficiently high to use a regional modeling program to correlate health effects on a Basin-wide level. On a regional scale, the quantity of emissions from the project is incrementally minor. Because the SCAQMD has not identified any other methods to quantify health impacts from small projects and due to the size of the project, it is speculative to assign any specific health effects to small project-related emissions. However, based on this localized analysis, the proposed project would not expose sensitive receptors to substantial pollutant concentrations. Therefore, the project would not expose sensitive receptors to substantial levels of pollutant concentrations. There would not be a new or worsening impact related to sensitive receptors than those included in the 2009 EIR. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» Odors The 2009 EIR found that there would be a less than significant impact related to objectionable odors due to implementation of the approved project during both construction and operation. Heavy-duty equipment on the project site during construction would emit odors, primarily from equipment exhaust. However, the construction activity would cease after individual construction is completed. No other sources of objectionable odors have been identified for the proposed project. The 2009 EIR concluded that adverse impact in terms of objectionable odors during construction would be less than significant, thus the proposed project would not result in a new significant impact. SCAQMD Rule 402 regarding nuisances states: “A person shall not discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health or safety of any such persons or the public, or which cause, or have a natural tendency to cause, injury or damage to business or property.” The proposed uses are not anticipated to emit any objectionable odors. Therefore, the proposed project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people. There would not be a new or worsening impact related to odors than those analyzed in the 2009 EIR. Greenhouse Gas Emission Impacts The following sections describe the proposed project’s construction- and operation-related GHG impacts and consistency with applicable GHG reduction plans. Generation of Greenhouse Gas Emissions This section describes the proposed project’s construction- and operational-related GHG emissions and contribution to global climate change. SCAQMD has not addressed emission thresholds for construction in its CEQA Air Quality Handbook; however, SCAQMD requires quantification and disclosure. Thus, this section discusses construction emissions. Construction Greenhouse Gas Emissions. The 2009 EIR concluded that GHG emissions released due to construction activities from the approved project would be less than significant. Construction activities associated with the proposed project would produce combustion emissions from various sources. Construction would emit GHGs through the operation of construction equipment and from worker and builder supply vendor vehicles for the duration of the approximately 6-year construction period. The combustion of fossil-based fuels creates GHGs such as CO2, CH4, and N2O. Furthermore, the fueling of construction equipment emits CH4. Exhaust emissions from on-site construction activities would vary daily as construction activity levels change. The implementation of air quality mitigation measures required under the Arboretum Specific Plan 2009 EIR, including Mitigation Measures 4.5.3a, 4.5.3c. and 4.5.6 would also support the reduction of construction related GHG emissions. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» As indicated above, SCAQMD does not have an adopted threshold of significance for construction- related GHG emissions. Instead, the construction GHG emissions should be amortized over the life of the project, defined as 30 years, added to the operational emissions, and that total compared to the applicable interim GHG significance threshold tier. Using CalEEMod, it is estimated that the proposed project would generate approximately 21,032 MT CO2e during construction of the proposed project. When annualized over the 30-year life of the project, annual construction emissions would be 701.1 MT CO2e per year. The 2009 EIR estimated that construction of the approved project would generate approximately 4,071 MT CO2e per year over approximately 7 to 8 years. Using 7 years, the total construction CO2e emissions from the approved project would be 28,497 MT CO2e. When annualized over the 30-year life of the project, annual construction emissions of the approved project are estimated to be 949.9 MT CO2e per year. Thus, construction of the proposed project would emit less CO2e than the Resort Village portion of the approved project. The 2009 EIR concluded that construction GHG emissions would be less than significant, thus the proposed project would not result in a new or worsening GHG emissions impacts from construction activities than those included in the 2009 EIR. Operational Greenhouse Gas Emissions. The 2009 EIR found that the impacts of the approved project related to global warming were considered less than significant with the implementation of energy conservation measures included as Mitigation Measure 4.5.4, and trip reduction measures included as Mitigation Measures 4.5.5 and 4.5.6. Long-term operation of the proposed project would generate GHG emissions from mobile, area, waste, water, and refrigerant sources as well as indirect emissions from sources associated with energy consumption. Mobile-source GHG emissions would include project-generated vehicle trips associated with trips to and from the proposed project. Area-source emissions would be associated with activities such as landscaping and maintenance on the project site and other sources. Waste source emissions generated by the proposed project include energy generated by landfilling and other methods of disposal related to transporting and managing project-generated waste. In addition, water source emissions associated with the proposed project are generated by water supply and conveyance, water treatment, water distribution, and wastewater treatment. GHG emissions for the proposed project were estimated using CalEEMod. Table I shows the estimated amortized construction and operational GHG emissions for the completed proposed project compared to the Resort Village portion of the approved project. As shown in Table I, the proposed project would generate 32,420.1 MT CO2e/yr, which is above the SCAQMD’s 3,000 MT CO2e per year threshold. The 2009 EIR concluded that since the SCAQMD and the CARB have no proposed or adopted significance criteria or methodologies for estimating a project’s contribution of greenhouse gases or evaluating its significance related to global climate change, no significance determination could be made at that time. The 2009 EIR then demonstrated that future development under the proposed Specific Plan would comply with the majority of 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» existing strategies, policies, and regulations to reduce potential GHG emissions. Thus, the impacts of the project related to global warming were considered less than significant with implementation of Mitigation Measures 4.5.4, 4.5.5, and 4.5.6. Table I: Approved Project and Proposed Greenhouse Gas Emissions Mobile Sources 23,842 1.0 1.1 24,228 Area Sources 326.8 <0.1 <0.1 327.2 Energy Sources 5,414.4 0.4 <0.1 5,432.6 Water Sources 156.0 2.6 0.1 239.6 Waste Sources 170.6 17.0 0.0 596.8 Refrigerant Sources 1,596.4 Amortized Construction GHG Emissions 701.1 Source: LSA (October 2025). CH4 = methane CO2 = carbon dioxide GHG = greenhouse gas N2O = nitrous oxide As shown in Table I, the estimated emissions for the Approved Project are 30,458.9 MT CO2e per year; thus, when compared to the approved project emissions, the proposed project would result in an increase of 2,662.2 MT CO2e per year. While the proposed project would result in slightly more emissions than those estimated to occur under the previously approved project, the increase in emissions would be below the SCAQMD recommended thresholds of significance for GHG emissions. Furthermore, implementation of Mitigation Measures 4.5.4, 4.5.5, and 4.5.6 would serve to reduce emissions associated with the proposed project. Since the increase in emissions associated with the proposed project would be below the SCAQMD’s 3,000 MT CO2e per year threshold, the proposed project would result in a less than significance impact with implementation of Mitigation Measures 4.5.4, 4.5.5, and 4.5.6. Therefore, the proposed project would also not result in new or worsening impacts related to GHG emissions from operational activities than those disclosed in the 2009 EIR. The following section analyzed the proposed project’s consistency with current GHG emissions reduction plans. Consistency with Greenhouse Gas Emissions Reduction Plans The proposed project was analyzed for consistency with the goals of the City General Plan, 2022 Scoping Plan, and the 2024–2050 RTP/SCS. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» Fontana General Plan The proposed project includes a Specific Plan Amendment (SPA) and General Plan Amendment (GPA), an amendment to the Development Agreement, and a revised Tentative Parcel Map. Each of these are described below: • General Plan Amendment No. 23-002 – would amend the General Plan to allow development of a proposed community retail site in the Resort Village, including changing the land use designation of the proposed 9.3-acre retail site from R-PC to C-G. • Specific Plan Amendment No. 23-002 – would amend the Arboretum Specific Plan to add approximately 9.3 acres of proposed community retail within the Resort Village at the northwest corner of Sierra and Terra Vista. The proposed community retail site would be anchored by a grocery store. The overall unit count in the Specific Plan would remain the same as originally approved. Within the Resort Village, residential planning areas and park sites have been relocated to accommodate the proposed community retail site. • Development Agreement No. 23-012 – would amend the development agreement, allowing the proposed community retail site to use existing excess fee credits. • Tentative Parcel Map No. 23-008 - Tentative Map 20646 includes 13 residential lots, one commercial lot, and a lettered lot for park purposes; this allows for the development of a 9.3 acre proposed community retail site. As described above, the project includes an amendment to the Arboretum Specific Plan to convert approximately 9.3 acres of the Resort Village planning area from R-MF (Residential Multi-Family, 8.0-16.0 du/ac) to C-1 (Community Commercial) and develop the 9.3-acre property with approximately 73,558 square feet of commercial uses. Additionally, residential land use designations within the Resort Village planning area would be revised to absorb the dwelling units initially attributed to the 9.3-acre parcel, in order to maintain the overall 3,532 dwelling units previously approved for buildout of the Specific Plan in the City of Fontana (City). The redistribution of units across the Resort Village planning area would preserve the acreage of lower density (6-8 du/ac) residential uses, decrease the acreage of middle density (8-16 du/ac) residential uses, and increase the acreage of higher density (16-20 du/ac) residential uses to make space for the proposed commercial uses in planning area C-1 The programmatic GHG reduction goals designed for City-wide implementation inherently reduce the GHG contribution of the proposed project because it is consistent with the City General Plan, zoning ordinance, and City growth projections and shall be developed in accordance with the latest edition of Title 24/CBC and CALGreen Code pursuant to Article XVIII (California Green Building Standards Code) of the City Municipal Code. Compliance with the latest edition of Title 24/CBC and CALGreen Code for energy and water conservation is required for all development projects as a matter of City and State policy. Through implementation of Title 24/CBC and CALGreen Code, the project would be developed in accordance with Goal 5 (Policy 1), Goal 6 (Policy 1 and Policy 2), and Goal 7 (Policy 1) outlined in Chapter 12, 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» Sustainability and Resilience of the City General Plan Update for purposes of reducing GHG emissions. Scoping Plan. Executive Order (EO) B-30-15 added the immediate target of reducing GHG emissions to 40 percent below 1990 levels by 2030. Senate Bill 32 affirms the importance of addressing climate change by codifying into statute the GHG emissions reductions target of at least 40 percent below 1990 levels by 2030 contained in EO B-30-15. The 2022 Scoping Plan assesses progress toward the statutory 2030 target, while laying out a path to achieving carbon neutrality no later than 2045. The 2022 Scoping Plan focuses on outcomes needed to achieve carbon neutrality by assessing paths for clean technology, energy deployment, natural and working lands, and others, and is designed to meet the State’s long-term climate objectives and support a range of economic, environmental, energy security, environmental justice, and public health priorities. The measures applicable to the proposed project include energy efficiency measures, water conservation and efficiency measures, and transportation and motor vehicle measures, as discussed below. The project would not impede the State’s progress towards carbon neutrality by 2045 under the 2022 Scoping Plan. The project would be required to comply with applicable current and future regulatory requirements promulgated through the 2022 Scoping Plan and is subject to applicable provisions of the California Energy Code and California Green Building Code, which identify minimum standards related to various building features, including electric vehicle charging capacity; appliances; water and space heating/cooling equipment; building insulation and roofing; and lighting. These measures are designed to expand the use of green building practices to reduce the carbon footprint of California’s new and existing inventory of buildings. With implementation of these green building practices, the project would not impede the State’s progress towards carbon neutrality by 2045 under the 2022 Scoping Plan. Water conservation and efficiency measures are intended to continue efficiency programs and use cleaner energy sources to move and treat water. Increasing the efficiency of water transport and reducing water use would reduce GHG emissions. As noted above, the proposed project would be required to comply with the latest Title 24 standards of the CCR, which include a variety of different measures, including reduction of wastewater and water use. Therefore, the proposed project would not conflict with water conservation and efficiency measures. The goal of transportation and motor vehicle measures is to develop regional GHG emissions reduction targets for passenger vehicles. Vehicles traveling to the project site would comply with the Pavley II (LEV III) Advanced Clean Cars Program. The project would also comply with the following additional transportation sector policies (through vehicle manufacturer compliance): Advanced Clean Cars II, Advanced Clean Trucks, Advanced Clean Fleets, Zero Emission Forklifts, the Off-Road Zero-Emission Targeted Manufacturer rule, Clean Off-Road Fleet Recognition Program, In-use Off- Road Diesel-Fueled Fleets Regulation, Off-Road Zero-Emission Targeted Manufacturer rule, Clean Off-Road Fleet Recognition Program, Amendments to the In-use Off-Road Diesel-Fueled Fleets Regulation, carbon pricing through the Cap-and-Trade Program, and the Low Carbon Fuel Standard. Therefore, the proposed project would not conflict with the identified transportation and motor vehicle measures. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» As such, the project would not conflict with implementation of the State’s Scoping Plan. SCAG’s Regional Transportation Plan/Sustainable Communities Strategy. SCAG’s 2024–2050 RTP/SCS identifies land use strategies that focus on new housing and job growth in areas served by high-quality transit and other opportunity areas would be consistent with a land use development pattern that supports and complements the proposed transportation network. The core vision in the 2024–2050 RTP/SCS is to better manage the existing transportation system through design management strategies, integrate land use decisions and technological advancements, create complete streets that are safe for all roadway users, preserve the transportation system, and expand transit and foster development in transit-oriented communities. The 2024–2050 RTP/SCS contains transportation projects to help more efficiently distribute population, housing, and employment growth, as well as a forecasted development pattern that is generally consistent with regional-level General Plan data. The forecasted development pattern, when integrated with the financially constrained transportation investments identified in the 2024–2050 RTP/SCS, would reach the regional target of reducing GHG emissions from autos and light-duty trucks by 8 percent per capita by 2020 and 19 percent by 2035 (compared to 2005 levels). The 2024–2050 RTP/SCS does not require that local General Plans, Specific Plans, or zoning be consistent with the 2024–2050 RTP/SCS, but it provides incentives for consistency for governments and developers. Implementing SCAG’s RTP/SCS would greatly reduce the regional GHG emissions from transportation, helping to achieve statewide emissions reduction targets. The proposed project is not regionally significant per State CEQA Guidelines Section 15206 and as such, it would not conflict with the SCAG RTP/SCS targets since those targets were established and are applicable on a regional level. In addition, the proposed project would not conflict with growth forecasts and is not expected to alter the demographic projections of SCAG; therefore, the proposed project is already reflected in SCAG’s 2024-2050 RTP/SCS and would not interfere with SCAG’s ability to achieve the region’s GHG reduction target of 19 percent below 2005 per capita emissions levels by 2035. Furthermore, the proposed project is not regionally significant per State CEQA Guidelines Section 15206 and as such, it would not conflict with the SCAG RTP/SCS targets since those targets were established and are applicable on a regional level. The 2009 EIR concluded that the approved project would comply with the majority of existing strategies, policies, and regulations to reduce potential GHG emissions and thus, the operational GHG emissions were less than significant with implementation of Mitigation Measure 4.5.6. Similar to the approved project, the proposed project would have a less than significant individual and cumulative impact related to GHG emissions. Therefore, the proposed project would not generate GHG emissions that would have a significant impact on the environment, nor would the project conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs. Associated impacts would be less than significant. Thus, the proposed project would not result in a new or worsening impact related to consistency with GHG emissions reductions plans, policies, or regulations than those analyzed in the 2009 EIR. 12/18/25 «P:\2023\20231028-Arboretum\Product\AQ-GHG\20231028 Arboretum Specific Plan Amendment AQ-GHG Memo 11-2025.docx» STANDARD CONDITIONS AND MITIGATION MEASURES The following standard conditions and measures from The Arboretum Specific Plan EIR are applicable to the proposed project and would be implemented to reduce and avoid potential impacts related to air quality and GHGs: Standard Condition 4.5.1 and Mitigation Measures 4.5.1, 4.5.2, 4.5.3a, 4.5.3b, 4.5.3c, 4.5.4, 4.5.5, and 4.5.6. CONCLUSION Construction of the proposed project would not exceed any SCAQMD emissions thresholds. While emissions from project operations would exceed some of the SCAQMD thresholds, based on the analysis presented above, neither construction nor operation of the proposed project would result in any new air quality or GHG emissions impacts as compared to those identified in the 2009 Arboretum Specific Plan EIR. The project would also be consistent with the 2022 AQMP. The proposed project is not expected to produce significant emissions that would affect nearby sensitive receptors. The project would also not result in objectionable odors affecting a substantial number of people. GHG emissions released during construction and operation of the project would be consistent with the City of Fontana’s, and other regional GHG reduction measures. When compared to the approved project emissions, the proposed project would result in an increase in operational GHG emissions. However, the increase in emissions associated with the proposed project would be below the SCAQMD’s 3,000 MT CO2e per year threshold. Therefore, the proposed project would result in a less than significant impact with implementation of Mitigation Measures 4.5.4, 4.5.5, and 4.5.6. As such, the proposed project would also not result in new or worsening impacts related to GHG emissions from operational activities than those disclosed in the 2009 EIR. Furthermore, the proposed project would be consistent with both the CARB Scoping Plan and the SCAG RTP/SCS.
