TECHNICAL MEMORANDUM
To: Richard Grunow, Director, Community Development, Redevelopment Services and Housing, City of Coronado
From: Sharon Toland, Senior Technical Specialist
RE: Air Quality Technical Memorandum for the 6th Cycle 2021–2029 Housing Element Update Date: February 16, 2024
CC: Ryan Binns, Senior Director, Environmental + Planning Consulting, Harris & Associates Att: 1, CalEEMod Results
Introduction
This memorandum provides the results of Harris & Associates’ analysis of the potential air quality impacts from implementation of the 6th Cycle 2021–2029 Housing Element Update (HEU or project). The effort would include amendments to the Coronado General Plan land use designations and City of Coronado (City) zoning designation for consistency with the HEU. The HEU would be consistent with existing state law and outlines the implementation plan of the City’s goals, policies, quantified objectives, and programs for the preservation, improvement, and development of housing for a sustainable future. Potential impacts of the Coronado General Plan land use designation and zoning changes have not yet been evaluated. Therefore, this analysis focuses on the land use designation and zoning changes in the HEU.

The City is on a narrow peninsula of land at the southwestern edge of the San Diego region. It is bounded by the Pacific Ocean to the west and the San Diego Bay to the east. The City is accessible by the 2-mile-long San Diego– Coronado Bridge from the east and State Route 75 from the south. The project area includes 10 opportunity sites throughout the City. Each opportunity site is assigned a number (e.g., Opportunity Site 1). Opportunity Sites 1 through 9 are generally bounded by Naval Air Station North Island to the west, Ocean Boulevard to the south, Glorietta Boulevard and Pomona Avenue to the east, and 1st Street to the north. Opportunity Site 10 is just south of the other opportunity sites on Naval Amphibious Base Coronado at Tulagi Road and, therefore, is under the jurisdiction of the U.S. Navy. The 10 opportunity sites are composed of 27 parcels of land and total approximately 199 acres. Currently, all 10 opportunity sites are at least partially developed and within approximately 0.5 mile of schools and commercial areas. This analysis focuses on the potential net increase in criteria pollutant emissions attributable to the net increase of an additional 538 dwelling units compared to existing development in the City.

Air Quality Analysis Background
Air quality laws and regulations have historically divided air pollutants into two broad categories: criteria air pollutants and non-criteria pollutants, or toxic air contaminants. The purpose of this memorandum is to evaluate the potential criteria air pollutant impacts of the project. Criteria air pollutants are a group of common air pollutants regulated by federal and state governments through ambient air quality standards based on criteria regarding the health and environmental effects of pollution. The criteria air pollutants pertinent to the analysis in this memorandum are carbon monoxide (CO), nitrogen oxides (NOx), ozone (O3), particulate matter (particulate matter measuring no more than 10 microns in diameter [PM10] and particulate matter measuring no more than Attachment 9
2 2.5 microns in diameter [PM2.5]), and sulfur dioxide (SO2). The following describes the health effects of these criteria air pollutants.

Carbon Monoxide
CO is a colorless, odorless, poisonous gas produced by combustion processes, primarily mobile sources. When CO gets into the body, it combines with chemicals in the blood and prevents blood from providing oxygen to cells, tissues, and organs. Because the body requires oxygen for energy, high-level exposure to CO can cause serious health effects, including death (USEPA 2023a).

Nitrogen Oxides
NOx is a general term pertaining to compounds including nitric oxide (NO), nitrogen dioxide (NO2), and other NOx. NOx is produced from burning fuels, including gasoline, diesel, and coal. NOx reacts with volatile organic compounds(VOCs) to form ground-level O3 (smog). NOx is linked to a number of adverse respiratory system effects (USEPA 2023b).

Ozone
Ground-level O3 is not emitted directly into the air but is formed by chemical reactions of “precursor” pollutants (NOx and VOCs) in the presence of sunlight. Major emissions sources include NOx and VOC emissions from industrial facilities and electric utilities, motor vehicle exhaust, gasoline vapors, and chemical solvents. O3 can trigger a variety of health problems, particularly for sensitive receptors, including children, older adults, and people of all ages who have lung diseases, such as asthma (USEPA 2023c).

Particulate Matter
Particulate matter includes dust, metals, organic compounds, and other tiny particles of solid materials that are released into and move around in the air. Particulates are produced by many sources, including the burning of diesel fuel by trucks and buses, industrial processes, and fires. Particulate pollution can cause nose and throat irritation and heart and lung problems. Particulate matter is measured in microns, which are 1 millionth of 1 meter in length (or 1 thousandth of 1 millimeter). PM10 is small (i.e., respirable) particulate matter measuring no more than 10 microns in diameter, while PM2.5 is fine particulate matter measuring no more than 2.5 microns in diameter (CARB 2024a).

Sulfur Dioxide
SO2 is formed primarily by the combustion of sulfur-containing fossil fuels, especially at power plants and industrial facilities. SO2 is linked to a number of adverse effects on the respiratory system (USEPA 2023d).

Existing Ambient Air Quality
The project is within the San Diego Air Basin (SDAB). The San Diego County Air Pollution Control District (SDAPCD) manages air quality in the SDAB. The SDAPCD operates a network of ambient air monitoring stations throughout the SDAB. The purpose of the monitoring stations is to measure ambient concentrations of pollutants and determine whether ambient air quality meets the California Ambient Air Quality Standards (CAAQS) and the National Ambient Air Quality Standards (NAAQS). The City does not have its own monitoring station. The closest monitoring station to the City is the Sherman Elementary School monitoring station, which measures O3, NO2, PM10, and PM2.5 concentrations on 24th Street in the City of San Diego. Concentrations of pollutants for O3, NO2, and PM2.5 are presented in Table 1, Monitored Ambient Air Quality at the Sherman Elementary School Monitoring Station. However, data is not available past 2019 for PM10. Therefore, concentrations of pollutants from the next closest monitoring station, the Chula Vista monitoring station, are presented in Table 2, Monitored Ambient PM10 at the Chula Vista Monitoring Station, for 2019, the most recent year available. Concentrations of 1‐hour O3 did not exceed CAAQS in 2020, 2021, or 2022. The 8‐hour O3 exceeded the CAAQS and NAAQS in 2020. The CAAQS for PM10 was exceeded once in 2019. The monitored 24‐hour PM2.5 values were exceeded in 2020. The 1-hour and annual NAAQS and CAAQS for NO2 were not exceeded.

Attachment 9
3 No CO data is available from monitoring sites in the SDAB after 2012, and no data is available for SO2 after 2013.

However, with one exception for CO during the October 2003 firestorms, the SDAB has not violated the NAAQS and CAAQS for CO or SO2 in the last 20 years (SDAPCD 2017).

Federal and State
The Clean Air Act (CAA) of 1970 required the U.S. Environmental Protection Agency (USEPA) to establish the NAAQS while retaining the option for states to adopt more stringent standards or to include other specific pollutants. The NAAQS were developed for six criteria pollutants: O3, NO2, CO, SO2, particulate matter, and lead.

The 1990 CAA Amendments require each state to have an Air Pollution Control Plan called a State Implementation Plan. A State Implementation Plan includes strategies and control measures to attain the NAAQS by deadlines Attachment 9
4 established by the CAA. The 1990 CAA Amendments dictate that states containing areas violating the NAAQS revise their State Implementation Plans to include extra control measures to reduce air pollution. The USEPA reviews the State Implementation Plans to determine whether the plans conform to the 1990 CAA Amendments and achieve the established air quality goals.

The USEPA has classified air basins (or portions thereof) as being in “attainment,” in “non-attainment,” or “unclassified” for each criteria air pollutant based on whether the NAAQS have been achieved. If an area is designated unclassified, it is because inadequate air quality data was available as a basis for a non-attainment or attainment designation. Table 3, San Diego Air Basin Attainment Status, lists the attainment status of the SDAB for the criteria pollutants. The USEPA classifies the SDAB as in non-attainment for O3 (8-hour) with respect to federal air quality standards. The State of California, under the California CAA, established standards for criteria pollutants that are generally stricter than federal standards. As shown in Table 3, the SDAB is currently in state non-attainment status for PM10, PM2.5, and O3 (1-hour and 8-hour).

Local
San Diego County Air Pollution Control District
The SDAPCD has jurisdiction over air quality programs in the County of San Diego. State and local government projects, as well as projects proposed by the private sector, are subject to SDAPCD requirements if the sources are regulated by the SDAPCD.

The SDAPCD is also responsible for establishing and enforcing local air quality rules and regulations that address the requirements of federal and state air quality laws. Development projects in the City are typically subject to the following SDAPCD rules; other rules may apply depending on the proposed specific operations:
• Rule 51, Nuisance. Prohibits emissions that cause injury, detriment, nuisance, or annoyance to any considerable number of people or to the public; endanger the comfort, repose, health, or safety of any such people or the public; or cause injury or damage to business or property. • Rule 52, Particulate Matter. Establishes limits to the discharge of any particulate matter from non‐stationary sources. • Rule 54, Dust and Fumes. Establishes limits to the amount of dust or fume discharged into the atmosphere in any 1 hour.
• Rule 55, Fugitive Dust Control. Sets restrictions on visible fugitive dust from construction and demolition projects. • Rule 67, Architectural Coatings. Establishes limits to the VOC content for coatings applied in the SDAPCD.

Attachment 9
5 Coronado General Plan
Multiple chapters in the Coronado General Plan include various goals and policies designed to improve and maintain air quality in the City. The Coronado General Plan goals and policies for improving air quality are as follows (City of Coronado 2003):
• Chapter A, Land Use
• Goal 2: Sufficient alternative land use opportunities should be allowed within the City to permit Coronado to be a viable, healthy, and nearly self-contained community. • Chapter B, Public Facilities
• Goal 1: Assure that public services are provided in a manner to minimize negative environmental impacts when possible.
• Chapter E, Circulation Element
• Goal 9: Reduce the adverse environmental and safety impacts and ameliorate the unpleasant side effects of traffic circulation (bulk, noise, fumes, clutter, cross traffic barrier and the physical isolation of areas from each other).

Significance Thresholds
Appendix G of the CEQA Guidelines states that significance criteria established by the applicable air quality management or air pollution control district may be relied on to make impact determinations. The City has not adopted significance thresholds to evaluate the significance of air quality impacts once a report has been deemed necessary. In lieu of any set quantitative air quality significance thresholds, the Air Quality Impact Analysis trigger levels in the SDAPCD’s Regulation II, Rule 20.2, Table 20.2-1, Air Quality Impact Analysis (AQIA) Trigger Levels, are used to determine the potential significance of air quality impacts. These Air Quality Impact Analysis trigger levels generally apply to new or modified stationary sources of air pollutants, which include only one source of air pollutant emissions. For CEQA purposes, the thresholds can be used to demonstrate that a project’s total emissions from all sources do not result in a significant impact to air quality (County of San Diego 2007). For VOC, the threshold established by the County of San Diego is used as the significance threshold. The thresholds are listed in Table 4, Screening Level Criteria Thresholds for Air Quality Impacts.

Table 4. Screening Level Criteria Thresholds for Air Quality Impacts Pollutant Emission Rate (pounds/day)
PM10 100
PM2.5 67
NOX 250
SOX 250
CO 550
VOC 75
Sources: CAPCOA 2022; County of San Diego 2007.

Notes: CO = carbon monoxide; NOX = nitrogen oxides; PM10 = particulate matter less than 10 microns; PM2.5 = particulate matter less than

2.5 microns; SOX = oxides of sulfur oxides; VOC = volatile organic compounds The thresholds listed in Table 4 represent screening level thresholds that can be used to evaluate if project-related emissions cause a significant impact on air quality. Emissions below the screening level thresholds do not cause a significant impact. For non-attainment pollutants (O3, with O3 precursors NOX and VOCs, and PM10), if emissions exceed the thresholds in Table 4, the HEU would result in a cumulatively considerable net increase in these pollutants and, thus, would have a significant impact on ambient air quality.

Construction Impact Analysis
Construction of future projects under the HEU would result in temporary air pollutants associated with soil disturbance, dust emissions, employee and material delivery vehicle exhaust, off-gassing from paving and coating Attachment 9
6 activities, and combustion pollutants from off-road construction equipment. Construction-related air pollution emissions can vary from day to day, depending on the level of activity, type of activity, and prevailing weather conditions. The primary air pollutants of concern from construction activities are particulate matter (including both PM10 and PM2.5), CO, and O3 precursors (including NOx and VOCs).

Maximum daily construction emissions were estimated using the California Emissions Estimator Model (CalEEMod), Version 2022.1. The projectis a land use plan and does not propose any specific construction projects, and the details of future construction under the HEU are currently unknown. Therefore, estimated maximum daily construction emissions were estimated using CalEEMod default assumptions. Construction of approximately 374 units on Opportunity Site 10 (Navy housing) would potentially overlap with construction of 538 residential units in the City.

Therefore, Opportunity Site 10 was included as a cumulative project in construction modeling for a total of 912 constructed units. Modeling assumes a buildout year of 2029. The recommended default assumption of 600 tons of export material per acre was used to estimate total earthwork and demolition export for the project (Ramboll 2023).

This is because the existing area is largely built out, reducing earthwork compared to an undisturbed site, but demolition and redevelopment would be necessary to accommodate the planned growth. Detailed assumptions and modeling datasheets are provided in Attachment 1, CalEEMod Results. Estimated maximum daily construction emissions are provided in Table 5, Estimated Maximum Daily Construction Emissions (pounds/day).

Notes: CO = carbon monoxide; NOx = oxides of nitrogen; PM10 = particulate matter less than 10 microns in diameter; PM2.5 = particulate matter less than 2.5 microns in diameter; SOx = sulfur oxides; VOC = volatile organic compounds As shown in Table 5, the construction emissions estimate indicates that development allowed under the HEU would not result in significant air emissions during construction. However, it should be noted that these results reflect default modeling assumptions for the amount of growth accommodated by the HEU rather than a proposed construction project. Realistically, construction emissions for all pollutants may be greater or lower depending on how development is implemented. It is assumed that future construction would include site watering twice per day in compliance with SDAPCD Rule 55, Fugitive Dust Rule, and low-VOC architectural coatings in compliance with SDAPCD Rule 67, Architectural Coatings.

Construction of future development consistent with the project would not result in significant criteria pollutant emissions during construction, and impacts would be less than significant.

Operational Impact Analysis
Long-term air pollutant emissions impacts are those associated with stationary sources and mobile sources involving any project-related changes. Stationary sources of emissions include the use of architectural coatings, consumer products, landscape equipment, and energy use. Area sources of air pollutant emissions associated with future development under the HEU include fuel combustion emissions from space and water heating, fuel combustion emissions from landscape maintenance equipment, VOC emissions from periodic repainting of Attachment 9
7 interior and exterior surfaces, and natural gas use. Increased traffic volumes also contribute to regional emissions of criteria pollutants.

The net increase in estimated operational emissions from implementation of the HEU was calculated using CalEEMod (Version 2022.1) using default assumptionsfor residential development. Operational emissions include the net increase of 538 residential units on opportunity sites under the jurisdiction of the City, consistent with the methodology of the project traffic impact analysis. Total daily vehicle miles traveled was provided by Linscott, Law & Greenspan, Engineers (LLG 2024). It is assumed that the new units would not include hearths or wood-burning stoves. Table 6, Net Change in Project Operational Emissions, provides calculated operational emissions for HEU buildout.

As shown in Table 6, operational emissions for HEU buildout would not exceed the SDAPCD thresholds for VOC, NOx, CO, SOx, PM10, and PM2.5. Development under the project would not contribute to the potentially existing significant cumulative impacts related criteria pollutant emissions. Therefore, impacts would be less than significant.

Mitigation Measures
No mitigation measures are required.

Summary
Construction and buildout operation of the HEU would not exceed the SDAPCD significance thresholds for criteria pollutants. Future development under the project would be required to comply with the California Air Resources Board motor vehicle standards, the SDAPCD regulations from stationary sources and architectural coatings, and the Coronado General Plan goals and policies. Therefore, impacts from construction and operation of the project would be less than significant.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 6.59 annual days of extreme heat Extreme Precipitation 2.55 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 1.66 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events.

Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Attachment 9
Coronado HEU - Unit Net Increase Detailed Report, 1/2/2024 88 / 93
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

The sensitivity score reflects the extent to which a project would be adversely affected by exposure to a climate hazard. Exposure is rated on a scale of 1 to 5, with a score of 5 representing the greatest exposure.

The adaptive capacity of a project refers to its ability to manage and reduce vulnerabilities from projected climate hazards. Adaptive capacity is rated on a scale of 1 to 5, with a score of 5 representing the greatest ability to adapt.

The overall vulnerability scores are calculated based on the potential impacts and adaptive capacity assessments for each hazard. Scores do not include implementation of climate risk reduction measures.

GHG EMISSIONS

TECHNICAL MEMORANDUM
To: Richard Grunow, Director, Community Development, Redevelopment Services and Housing, City of Coronado
From: Sharon Toland, Senior Technical Specialist, Harris & Associates RE: Greenhouse Gas Emissions Technical Memorandum for the 6th Cycle 2021–2029 Housing Element Update Date: February 12, 2024
CC: Ryan Binns, Senior Director, Environmental + Planning Consulting, Harris & Associates Att: 1, CalEEMod Results
Introduction
This memorandum presents the results of Harris & Associates’ analysis of the potential impacts to greenhouse gas (GHG) emissions from implementation of the 6th Cycle 2021–2029 Housing Element Update (HEU or project). The effort would include amendments to the Coronado General Plan land use designations and City of Coronado (City) zoning designation for consistency with the HEU. The HEU would be consistent with existing state law and outlines the implementation plan of the City’s goals, policies, quantified objectives, and programs for the preservation, improvement, and development of housing for a sustainable future. Potential impacts of the Coronado General Plan land use designation and zoning changes have not yet been evaluated. Therefore, this analysis focuses on the land use designation and zoning changes in the HEU.

The City is on a narrow peninsula of land at the southwestern edge of the San Diego region. It is bounded by the Pacific Ocean to the west and the San Diego Bay to the east. The City is accessible by the 2-mile-long San Diego– Coronado Bridge from the east and State Route 75 from the south. The project area includes 10 opportunity sites throughout the City. Each opportunity site is assigned a number (e.g., Opportunity Site 1). Opportunity Sites 1 through 9 are generally bounded by Naval Air Station North Island to the west, Ocean Boulevard to the south, Glorietta Boulevard and Pomona Avenue to the east, and First Street to the north. Opportunity Site 10 is just south of the other opportunity sites on Naval Amphibious Base Coronado at Tulagi Road and, therefore, is under the jurisdiction of the U.S. Navy. The 10 opportunity sites are composed of 27 parcels of land and total approximately 199 acres. Currently, all 10 opportunity sites are at least partially developed and within approximately 0.5 mile of schools and commercial areas. This analysis focuses on the potential net increase in GHG emissions attributable to the net increase of an additional 538 units compared to existing development in the City.

Greenhouse Gas Analysis Background
A GHG is any gas that absorbs infrared radiation and traps heat in the atmosphere. GHGs are produced from natural processes and human activities. The accumulation of GHGs in the atmosphere influences the long-term atmospheric temperatures and contributes to global climate change. Carbon dioxide (CO2) accounts for the largest amount of GHG emissions, and collectively, CO2, methane (CH4), and nitrous oxide (N2O) amount to approximately 97 percent of total GHG emissions in the United States (USEPA 2023).

Attachment 9
2 For each GHG, a global warming potential has been calculated to reflect how long emissions remain in the atmosphere and how strongly each GHG absorbs energy on a per-kilogram basis relative to CO2. For example, 1 pound of CH4 has 25 times more heat-capturing potential than 1 pound of CO2. To simplify reporting and analysis, GHG emissions are typically reported in metric tons of carbon dioxide equivalent (MT CO2e). Global warming potential is a metric that indicates the relative climate forcing of 1 kilogram of emissions when averaged over the period of interest. Table 1, Global Warming Potential for Select Greenhouse Gases, identifies the CO2e and atmospheric lifetimes of basic GHGs.

Table 1. Global Warming Potential for Select Greenhouse Gases Pollutant Atmospheric Lifetime (years) Global Warming Potential (100-year)b CH4 12 25

Notes: CH4 = methane; CO2 = carbon dioxide; N2O = nitrous oxide a CO2 has a variable atmospheric lifetime and cannot be readily approximated as a single number. b The warming effects over a 100-year period relative to other GHGs.

Regulatory Setting
Federal
The U.S. Environmental Protection Agency is responsible for implementing federal policy to address global climate change. In 2009, the U.S. Environmental Protection Agency issued a final rule for mandatory reporting of GHG emissions, which applies to fossil fuel and industrial gas suppliers, direct GHG emitters, and manufacturers of heavyduty and off-road vehicles and requires annual reporting of emissions. This final rule does not regulate the emissions of GHGs; it only requires the monitoring and reporting of GHGs for the specified sources above certain thresholds.

State
California has enacted a variety of legislation related to climate change, much of which has set aggressive goals for GHG emissions reductions throughout the state. Executive Order S-03-05 (2005) established the goal of reducing GHG emissions to 2000 levels by 2010, 1990 levels by 2020, and 80 percent below 1990 levels by 2050.

In September 2006, Governor Arnold Schwarzenegger signed California’s Global Warming Solutions Act of 2006 (Assembly Bill [AB] 32), requiring the California Air Resources Board to establish a statewide GHG emissions cap for 2020 based on 1990 emissions and to adopt mandatory reporting rules for significant sources of GHG emissions. In April 2015, Governor Jerry Brown signed Executive Order B-30-15, which established the goal of reducing GHG emissions to 40 percent below 1990 levels by 2030. This goal was set into law in Senate Bill 32.

AB 1279, the California Climate Crisis Act, enacted in September 2022, updated the goals of AB 32. The bill established a statewide goal to achieve net-zero GHG emissions by 2045 and to achieve and maintain net-negative GHG emissions thereafter. Additionally, the bill established a specific target for statewide anthropogenic GHG emissions to be reduced to at least 85 percent below 1990 levels by 2045.

Local
The City adopted a Climate Action Plan (CAP) in March 2022 (City of Coronado 2022). The Coronado CAP represents a roadmap by which the City can reduce its contributions of GHG emissions through the development and implementation of strategies that mirror the City’s goals, values, and priorities in support of the state’s efforts under Senate Bill 32. In summer 2020, a GHG emissions inventory was completed using a 2016 baseline year to identify existing emissions sources and the magnitude of their emissions. The results of the inventory indicate that, in 2016, activities in the City resulted in approximately 113,000 MT CO2e, or approximately 6.3 MT CO2e per City resident. The transportation sector represents the largest single source of community emissions at approximately 43 percent of the 2016 inventory. The Coronado CAP establishes a goal of reducing emissions by Attachment 9
3 39.4 percent compared to 2016 levels by 2030 to be consistent with the Senate Bill 32 efforts to reduce emissions by 40 percent compared to 1990 levels by 2030. A 39.4 percent reduction would result in a 2030 reduction goal of 68,333 MT CO2e, or 3.7 MT CO2e per capita. The Coronado CAP identifies 17 voluntary strategies to meet the reduced target related to increased use of electric vehicles (EVs) and alternative transportation, solar energy, and recycled water and increased waste diversion.

Significance Thresholds
The Coronado CAP is a voluntary CAP that does not meet the requirements for tiering in accordance with the California Environmental Quality Act (CEQA) Guidelines, Section 15183.5. Additionally, the San Diego County Air Pollution Control District has not adopted a numeric GHG threshold. The California Air Resources Board’s 2022 Scoping Plan for Achieving Carbon Neutrality (2022 Scoping Plan) outlines a statewide path to achieving the net-zero statewide emissions goal of AB 1279. The 2022 Scoping Plan outlines key strategies for land use plans for consistency with the goals of the plan. In the absence of an adopted local plan, the 2022 Scoping Plan has been determined to be the appropriate tool for determining the significance of project GHG emissions. The project would result in a potentially significant impact related to GHG emissions if it conflicted with implementation of the 2022 Scoping Plan. Additionally, although the Coronado CAP is not qualified to determine the significance of GHG emissions, it is an applicable plan to reduce GHGs, and the project is evaluated for CAP consistency.

Project Emissions Inventory
Construction
Project construction emissions were estimated using the California Emissions Estimator Model (CalEEMod), Version 2022.1. The project is a land use plan and does not propose any specific construction projects, and the details of future construction under the HEU are currently unknown. Therefore, estimated maximum daily construction emissions were estimated using CalEEMod default assumptions for construction of 538 residential units. Modeling assumes a buildout year of 2029. The recommended default assumption of 600 tons of export material per acre was used to estimate total earthwork and demolition export for the project (Ramboll 2023). This is because the existing area is largely built out, reducing earthwork compared to an undisturbed site, but demolition and redevelopment would be necessary to accommodate the planned growth. Detailed assumptions and modeling datasheets are provided in Attachment 1, CalEEMod Results. Construction of 538 residential units is estimated to result in average annual construction emissions of 678 MT CO2e per year between 2024 and 2029.

Operation
During operation, business-as-usual (BAU) buildout1 under the HEU would result in area and indirect emissions sources from electricity and natural gas consumption, water and wastewater transport, and solid waste generation. GHG emissions from electricity consumed on site by the project would be generated off site by fuel combustion at the electricity provider. GHG emissions from water and wastewater transport would be indirect emissions resulting from the energy required to transport water from its source and the energy required to treat wastewater and transport it to its treated discharge point. Development would also generate mobile source emissions from motor vehicle trips. The project does not propose any specific future development projects.

Operational GHG emissions associated with the net increase in residential units accommodated by the project are shown in Table 2, Estimated Project-Related Operational Greenhouse Gas Emissions. This net increase in annual operational emissions from HEU buildout conditions are based on CalEEMod default utility use estimates and vehicle miles traveled (VMT) data from the Transportation Analysis (LLG 2024). 1 A BAU scenario is one that assumes no additional GHG reduction efforts (e.g., CAP reduction strategies) beyond what have already been adopted and accounted for in CalEEMod. For example, CalEEMod estimates energy use based on 2019 consumption rates and projected 2025 San Diego Gas & Electric energy emissions factors (CAPCOA 2022). It does not account for the 2022 Title 24 energy efficiency standards and future standards that have not yet been adopted or selection of San Diego Community Power as an energy provider.

As shown in Table 2, buildout of new residential units under the HEU would result in a net increase in GHG emissions compared to existing conditions. Additionally, the project would require a General Plan Amendment and Zoning Designation Amendment to reflect the HEU. However, the HEU is intended to address projected housing needs to accommodate anticipated future growth, consistent with local and regional planning. It would not induce growth in the City or region. Additionally, the estimated GHG emissions in Table 2 are conservative and do not take into account that the project would increase housing in an existing developed area within proximity to existing schools and commercial development or that new and redeveloped housing units would be subject to increasingly strict building standards that would reduce GHG emissions. The project would accommodate the City’s Regional Housing Needs Assessment allocation issued by the San Diego Association of Governments and consistent with state housing goals. Because the project addresses identified statewide housing needs to meet projected growth, it would not result in unplanned forecasted GHG emissions. Project consistency with the key strategies of these plans is addressed below.
2022 Scoping Plan
The primary plan for determining the significance of project emissions in line with current state emissions reduction goals is the 2022 Scoping Plan, which outlines a path for achieving carbon neutrality in accordance with AB 1279. The 2022 Scoping Plan recommends that local governments prioritize transportation electrification, VMT reduction, and building decarbonization (CARB 2022). Specifically, Appendix D, Local Actions, of the 2022 Scoping Plan outlines recommendations for local government action to be implemented at the plan level to facilitate 2022 Scoping Plan implementation. A key local action for 2022 Scoping Plan implementation is a local CAP. As described previously, the City has an adopted voluntary CAP. Project consistency with the City’s current CAP is evaluated below. However, the Coronado CAP does not specifically address the City’s fair share of GHG reductions under AB 1279, and the HEU is further evaluated for consistency with the 2022 Scoping Plan Appendix D discussion of the role of land use plans, such as supporting state emissions reduction goals. Increased housing availability is a key focus of this discussion. The discussion highlights the opportunity for land use plans to eliminate barriers to facilitate infill development. The proposed HEU would accommodate additional housing in a primarily developed area near existing schools and commercial uses, which would be consistent with this goal. The plan also identifies key project attributes for new residential projects. An individual residential development project may be considered to have a less than significant impact related to GHG emissions if it:
• Would include EV charging infrastructure that meets the most ambitious voluntary standards in the California Green Building Standards Code
• Would be located on an infill or under-developed site surrounded by existing urban uses • Does not result in the loss or conversion of natural and working lands • Satisfies regional-specific VMT reduction criteria
• Reduces parking requirements
Attachment 9
5 • Includes at least 20 percent of units that are affordable to lower-income households • Results in no net loss of existing affordable housing • Uses all-electric appliances without any natural gas connections and does not use propane or other fossil fuels for space heating, water heating, or indoor cooking
New residential development under the HEU would be on infill sites and would not result in the loss or conversion of natural and working lands. The Transportation Analysis for the project determined that project VMT per resident would be 14.98 miles per resident, which is below the 85 percent regional average VMT threshold of 16.1 miles (LLG 2024). Additionally, a key component of the HEU is to expand the availability of affordable dwelling units. As such, the HEU would be consistent with 2022 Scoping Plan criteria for residential development that may be implemented at the planning level as appropriate for a Housing Element. The remaining criteria, including EV charging infrastructure and use of electric appliances, are project-specific design requirements. These requirements may be incorporated into future applicable local or state regulations, such as the Coronado Zoning Ordinance or the California Green Building Standards, or the next update to the Coronado CAP. Changesto parking requirements would occur as updates to the Coronado Municipal Code and would be beyond the HEU’s scope.

Until these design elements are codified or the Coronado CAP has been updated to a qualified CAP consistent with the most recent state emissions reduction goals, future residential development under the HEU would need to demonstrate consistency with the 2022 Scoping Plan key project attributes for residential development to have a less than significant impact related to GHG emissions. Alternatively, the 2022 Scoping Plan notes that projects that result in net-zero GHG emissions may also be considered to have a less than significant impact related to GHG emissions. However, this also cannot be demonstrated at the programmatic level. This impact would be potentially significant.

Coronado Climate Action Plan
The Coronado CAP includes local strategies that would contribute to GHG reductions in the City to achieve reductions through 2030 and beyond. Local strategies cover sources within the on-road transportation, energy, water, and waste sectors. Local strategies include new programs that would be implemented City-wide, such as an EV carshare program, a neighborhood EV infrastructure program, increased transit frequency, reduced transit fares, electrification and expansion of shuttle and ferry service, implementation of an Active Transportation Plan, electrification of City fleet vehicles, public outdoor lighting upgrades, increases in the City’s renewable energy portfolio, recycled water use expansion, and increased solid waste diversion. Measures also encourage new EV infrastructure, consistent with key project attributes identified in the 2022 Scoping Plan, and new solar residential projects. The HEU would not include any components that would conflict with implementation of these programs or preclude the installation of EV or solar infrastructure at new residential units. Future development would be required to comply with any local or state regulations adopted to implement GHG reduction strategies, such as waste diversion requirements or California Green Building Standards related to solar panel installation at new residential development. The HEU does not included any components that would conflict with the City’s CAP. This impact would be less than significant.

Mitigation Measures
In the absence of a local qualified CAP, future residential projects would need to demonstrate consistency with the state emissions reductions goals to demonstrate a less than significant impact related to GHG emissions.

The purpose of the HEU is to provide opportunities for much needed housing in the City, consistent with state mandates. Consistent with standard industry practice (CAPCOA 2008; Sacramento Metropolitan Air Quality Management District 2014; SCAQMD 2008), a capture rate of approximately 90 percent of emissions has been identified as a screening level for GHG mitigation. A 90 percent emissions capture rate means that 90 percent of total emissions from new residential projects would be subject to additional GHG analysis and mitigation consistent with the 2022 Scoping Plan. The intent of the screening level is to capture a substantial fraction of future projects while setting the emissions threshold high enough to exclude small projects that will in aggregate contribute a relatively small fraction of the cumulative local statewide GHG emissions. Implementation of Attachment 9
6 mitigation beyond state requirements may present a disproportionate barrier to development for small projects that would provide a meaningful contribution to local housing needs.

A screening level of 20 units was determined to be the appropriate screening level to capture a significant portion of project GHG emissions. Based on the results on the City’s Sites Inventory for each opportunity site, opportunity sites that would accommodate 20 units or less would result in total annual GHG emissions of approximately 675 MT CO2e.
2 These emissions account for less than 10 percent of the 7,251 MT CO2e estimated for HEU implementation and would also represent less than 1 percent of the City’s 2030 target emissions of 68,333 MT CO2e identified in the Coronado CAP (City of Coronado 2022).

Additionally, although the 2022 Scoping Plan encourages eliminating parking minimums, this project attribute potentially conflicts with the 2022 Scoping Plan and Coronado CAP priority to provide new EV charging stations.

Therefore, it is more appropriate to encourage transportation electrification in the City for projects to not exceed existing parking minimums and provide ample EV infrastructure within these requirements.

Implementation of Mitigation Measure GHG-1 would reduce impacts related to future development under the HEU to a less than significant level.

GHG-1: Scoping Plan Consistency. Future residential development projects that include more than 20 units and that would be subject to a discretionary permitshall demonstrate consistency with the 2022 Scoping Plan.

This measure shall be superseded by consistency with a qualified Coronado Climate Action Plan, if adopted. Prior to obtaining a building permit, development projects shall demonstrate 2022 Scoping Plan consistency by showing consistency with the following project attributes or identifying and quantifying project features that would result in equal greenhouse gas emissions reductions:
• Project provides electric vehicle charging infrastructure that, at minimum, meets the most ambitious voluntary standard in the California Green Building Standards Code at the time of project approval. • Project would result in a less than significant impact related to vehicle miles traveled. • Project does not provide parking beyond minimum required parking. • For multi-unit projects, at least 20 percent of units are affordable to lower-income households. • Project results in no net loss of existing affordable housing. • Project uses all-electric appliances without any natural gas connections and does not use propane or other fossil fuels for space heating, water heating, or indoor cooking.

Summary
Implementation of the project would have the potential to result in a net increase in GHG emissions. The HEU would be consistent with the Coronado CAP and implement all appropriate plan-level recommendations of the 2022 Scoping Plan. However, future residential development would need to implement key project-specific design attributes to demonstrate consistency with statewide emissions reductions goals as outlined in the 2022 Scoping Plan. Mitigation Measure GHG-1 would reduce impacts related to GHG emissions to a less than significant level.
