Subject: Air Quality and Greenhouse Gas Analysis for the Del Valle Restaurant DriveThru Addition in Santa Rosa, CA Dear Mr. Navarro:

Yorke Engineering, LLC (Yorke) is pleased to provide this Air Quality (AQ) and Greenhouse Gas (GHG) Report. This AQ/GHG Report includes CalEEMod emissions estimates, criteria pollutant analysis, and GHG analysis for the proposed Del Valle Restaurant Drive-Thru addition in the City of Santa Rosa, California (the City), which is the county seat of Sonoma County and within the jurisdiction of the Bay Area Air Quality Management District (BAAQMD). The City Planner has requested an air quality and GHG study to determine if this project qualifies for CEQA Class 32 infill project exemption.

PROJECT DESCRIPTION AND LOCATION
The Del Valle Restaurant (Applicant) is proposing to construct a drive-thru as an extension of the existing restaurant located at 2000 Sebastopol Road, Santa Rosa, CA. The proposed drive-thru will consist of an 850-square-foot food service building on the western side of the property, and a 12- foot wide drive aisle with a 3-foot tall hedge/fence for screening of the aisle and associated car headlights from Sebastopol Road on the north. Additionally, the project will provide 14 standard parking spaces and one Americans with Disabilities Act (ADA) compliant space, for a total of 15 new paved parking spaces. A 120-square-foot trash bin enclosure will be located opposite the food service building on the eastern side of the property, adjacent to the drive-thru queue lane entrance.

Figure 1 shows the project location. The site plan is shown in Figure 2.

The site plan shows that vehicles will enter the drive-thru from Sebastopol Road. The City has requested from the Applicant a queue management plan in case the drive-thru queue lane approaches or exceeds design capacity, risking overflow onto Sebastopol Road. If that situation occurs, the Applicant plans on blocking off the drive-thru queue lane and diverting customers through the easement that provides access from the Rite Aid parking lot next door.

A traffic study was performed to evaluate the potential morning (a.m.), and evening (p.m.) peak hour impacts associated with operation of the proposed drive-thru (W-Trans 2022). The queue is designed to handle the peak traffic demand with no impact on the surrounding neighbors.

CalEEMod was used to estimate the average daily trip rates needed to calculate mobile source emissions impacts for the operational air quality and GHG analysis.

ENVIRONMENTAL SETTING
The project site is situated within the San Francisco Bay Area Air Basin (SFBAAB), which includes the counties of San Francisco, Alameda, Contra Costa, Marin, San Mateo, Santa Clara, and Napa, as well as the southern and southwestern portions of Sonoma and Solano counties. The BAAQMD is the regional air district responsible for managing air quality planning across this extensive area. The Project is within the jurisdiction of the BAAQMD, which provides the applicable California Environmental Quality Act (CEQA) thresholds of significance used for the evaluation of potential air quality and greenhouse gas impacts.

AIR POLLUTANTS
The U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) have set national and state air quality standards for seven key pollutants, known as criteria pollutants: ozone (O₃), particulate matter (PM10 and PM2.5), carbon monoxide (CO), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), and lead. Additionally, CARB has established state-specific ambient air quality standards for four more pollutants: visibility-reducing particles, sulfates, hydrogen sulfide, and vinyl chloride.

Below is a brief overview of each criteria pollutant and its associated health impacts:

O₃: Ozone is a nearly colorless gas created through a photochemical reaction, where nitrogen dioxide is broken down by sunlight. At ground level, ozone exposure can lead to various health issues, including lung irritation, wheezing, coughing, pain during deep breaths, and breathing difficulties during physical activities. It can also cause permanent lung damage, worsen asthma, and increase the risk of respiratory illnesses.

CO: Carbon monoxide is a colorless, odorless, and toxic gas primarily produced by the incomplete combustion of fossil fuels in vehicles. CO binds with hemoglobin in the blood, reducing the amount of oxygen that can be transported throughout the body. High concentrations of CO can result in headaches, exacerbate cardiovascular conditions, and impair central nervous system functions.

NOx: Nitrogen oxides are yellowish-brown gases that can cause breathing difficulties at elevated levels. They are formed when nitric oxide, a pollutant from internal combustion processes, reacts with oxygen.

SO₂: Sulfur dioxide is a colorless gas with a pungent odor, mainly produced by burning sulfur-containing fossil fuels. It can lead to acute respiratory symptoms and breathing difficulties, particularly in children.

PM10 and PM2.5: Particulate matter refers to tiny particles suspended in the air. PM10 includes particles with diameters of ten microns or smaller, while PM2.5 refers to particles with diameters of 2.5 microns or smaller. These fine particles pose a greater health risk than larger particles, as they can more easily cause irritation. Examples include fugitive dust. Short-term exposure to high levels of PM2.5 is linked to increased mortality rates and higher rates of hospital admissions and emergency visits. Long-term exposure to high PM2.5 levels is associated with premature mortality and chronic respiratory diseases. Shortterm exposure to high PM10 levels can lead to hospital admissions for cardiopulmonary conditions, increased respiratory symptoms, and potentially premature mortality.

ATTAINMENT STATUS
The federal Clean Air Act (CAA) mandates that EPA set health-based National Ambient Air Quality Standards (NAAQS) for six criteria pollutants, designate nonattainment areas, and establish planning requirements. In California, the state sets its own ambient air quality standards, known as California Ambient Air Quality Standards (CAAQS), which require gradual progress toward meeting these standards. The attainment status is shown in Table 1 for the SFBAAB.

To achieve the NAAQS, the District and CARB have developed several State Implementation Plans (SIPs). These plans, which build on the achievements of previous ones, outline strategies for continued air quality improvements in the Bay Area. After each SIP is adopted, the BAAQMD works to implement the plan’s strategies through regulatory development, outreach, research, and incentive programs.

GREENHOUSE GASES
GHG emissions play a critical role in determining the Earth’s surface temperature. A portion of the solar radiation that enters the Earth’s atmosphere is absorbed by the Earth’s surface, and a smaller portion of this radiation is reflected back toward space. Infrared radiation (i.e., thermal heat) is absorbed by GHGs. As a result, infrared radiation released from the Earth that otherwise would have escaped back into space is instead “trapped,” resulting in a warming of the atmosphere.

This phenomenon, known as the “greenhouse effect,” is responsible for maintaining a habitable climate on Earth. However, high atmospheric concentrations of GHG due to anthropogenic GHG emissions are thought to contribute to climate change (i.e., global warming).

GHGs are present in the atmosphere naturally, are released by natural sources, and are formed from secondary reactions taking place in the atmosphere. The following are GHGs that are widely seen as the principal contributors to human-induced global climate change: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur Del Valle Restaurant Drive-Thru Addition

hexafluoride (SF6), and nitrogen trifluoride (NF3). Common refrigerant GHGs (abbreviated as “R”) used in air conditioning and refrigeration equipment, some of which are HFCs are also included in this analysis.

Global warming potential (GWP) is a concept developed to evaluate the ability of each GHG to trap heat in the atmosphere in comparison to carbon dioxide. The GWP of a GHG is based on several factors, including the relative effectiveness of a gas to absorb infrared radiation and the length of time that the gas remains in the atmosphere (atmospheric lifetime). The GWP of each gas is measured relative to carbon dioxide. GHGs with lower emissions rates than carbon dioxide may still contribute to climate change because they are more effective than carbon dioxide at absorbing outgoing infrared radiation (i.e., high GWP). The concept of carbon dioxide equivalent (CO2e) is used to account for the different GWP potentials of GHGs to absorb infrared radiation.

REGULATORY SETTING
Criteria Air Pollutants
The BAAQMD has been delegated authority under the federal and California CAAs to implement measures to protect air quality within the SFBAAB. The BAAQMD regulates stationary sources (with respect to federal, state, and local regulations), monitors regional air pollutant levels, and develops air quality control strategies. The BAAQMD requires Permits to Operate (PTOs) for stationary equipment and operations that emit criteria pollutants and/or Toxic Air Contaminants (TACs) into the atmosphere unless excluded by exemption. Permits issued by the BAAQMD include an assessment of compliance with CEQA.

The most recent air quality plan developed by the BAAQMD is the 2017 Clean Air Plan that was adopted by the BAAQMD in April 2017. The 2017 Clean Air Plan provides a regional strategy to protect public health and the climate. To protect public health, the plan describes how the BAAQMD will continue making progress toward attaining all state and federal air quality standards and eliminating exposure to air pollution among Bay Area communities. The 2017 Clean Air Plan includes a wide range of control measures designed to decrease emissions of the air pollutants that are most harmful, such as PM, ozone precursors, and TACs, and to decrease emissions of CO2 by reducing fossil fuel combustion. The 2017 Clean Air Plan represents the Bay Area’s most recent assessment of the region’s strategy to attain the state and national O3 and PM2.5 standards.

On April 20, 2022, the BAAQMD’s Board of Directors adopted CEQA Thresholds for Evaluating the Significance of Climate Impacts from Land Use Projects and Plans (BAAQMD 2022) (CEQA Guidelines). The Air District’s CEQA Guidelines supports lead agencies in assessing air quality and climate impacts from proposed land use projects and plans in the air basin. These Guidelines provide nonbinding recommendations on how lead agencies can evaluate, measure, and mitigate air quality and climate impacts resulting from construction and operational activities associated with land use.

Greenhouse Gases
AB 32, signed into law by Governor Arnold Schwarzenegger in 2006, established regulatory, reporting, and market mechanisms to achieve quantifiable reductions in GHG emissions and established a cap on statewide GHG emissions. It required that statewide GHG emissions be reduced to 1990 levels by 2020. AB 32 identifies CARB as the state agency responsible for the Del Valle Restaurant Drive-Thru Addition

design and implementation of emission limits, regulations, and other measures to meet the targets.

In 2016, California’s GHG emissions dropped below the AB 32 limit and have remained below the 2020 GHG limit since that time. In 2020, emissions from GHG emitting activities statewide were 369.2 million metric tons (MMT) of CO2e, 35.3 MMTCO2e lower than 2019 levels and 61.8 MMTCO2e below the 2020 GHG limit of 431 MMTCO2e (CARB 2022).

The 2017 Clean Air Plan lays the groundwork for a long-term effort to reduce Bay Area GHG emissions to 40% below 1990 levels by 2030 and 80% below 1990 levels by 2050. In addition, the BAAQMD established a climate protection program to reduce pollutants that contribute to global climate change and affect air quality in the SFBAAB. The program includes GHGreduction measures that promote energy efficiency, reduce VMT, and develop alternative energy sources (BAAQMD 2017).

On a local level, the City of Santa Rosa’s Climate Action Plan (CAP) incorporates the BAAQMD’s expectations for a Qualified GHG Reduction Strategy and represents a comprehensive approach to addressing climate change and reducing GHG emissions within the city. This plan articulates Santa Rosa’s commitment to environmental stewardship and provides a roadmap for transitioning towards greater sustainability. At its core, the 2012 CAP sets ambitious GHG reduction targets. It aims to cut emissions by 25% below 1990 levels by the year 2020 and by 80% below 1990 levels by 2050. These targets align with broader regional and state climate goals, signaling Santa Rosa’s dedication to making a significant impact on climate change over the coming decades.

The plan outlines strategies tailored to various sectors that are major contributors to GHG emissions. In the energy sector, the CAP emphasizes improving energy efficiency and promoting the use of renewable energy sources. It includes initiatives for reducing energy consumption across residential, commercial, and municipal buildings. For transportation, the CAP focuses on expanding alternative modes of transport such as public transit, enhancing infrastructure for pedestrians and cyclists, and supporting the adoption of electric vehicles. This sector-specific approach aims to reduce emissions from one of the largest sources of GHGs.

Waste management is another critical area addressed in the CAP. The plan advocates for increased recycling and composting, aiming to minimize the amount of waste sent to landfills. By encouraging the use of sustainable materials and reducing waste, Santa Rosa seeks to cut down on emissions associated with waste processing.

Water conservation also features prominently in the plan. It highlights the need for efficient water use to lower the energy required for water treatment and distribution, thereby contributing to GHG reductions.

To ensure the effectiveness of these strategies, the CAP emphasizes the importance of both implementation and ongoing monitoring. Regular reviews and updates to the plan are intended to keep it aligned with new data, technological advancements, and evolving regulations. This adaptive approach helps maintain progress towards the city's climate goals.

Appendix E of the City of Santa Rosa’s 2012 Climate Action Plan is specifically focused on the "CAP New Development Checklist." This checklist is an essential tool designed to ensure that new development projects align with the city’s climate action goals and contribute to its GHG reduction targets.

The checklist serves as a practical guide for developers and city planners, outlining the key measures and best practices that new projects should incorporate to minimize their environmental impact. It provides a structured approach to integrating sustainability into the development process, helping to ensure that new projects are designed and implemented in a way that supports the city's overall climate objectives.

Key Components of the Checklist
The CAP New Development Checklist includes various criteria related to different aspects of a development project. These typically cover:

1. Energy Efficiency: The checklist emphasizes the importance of incorporating energyefficient design and technologies in new buildings. This may include measures such as high-performance insulation, energy-efficient windows, and advanced heating, ventilation, and air conditioning (HVAC) systems. By prioritizing energy efficiency, new developments can significantly reduce their energy consumption and associated GHG emissions.

2. Renewable Energy: Developers are encouraged to integrate renewable energy sources, such as solar panels, into their projects. This aligns with the CAP’s goals by promoting the use of clean energy and reducing reliance on fossil fuels.

3. Water Conservation: The checklist includes criteria for water-saving measures, such as low-flow fixtures and drought-tolerant landscaping. Efficient water use is crucial for reducing the energy needed for water treatment and distribution, thus lowering GHG emissions.

4. Sustainable Transportation: The checklist promotes transportation-related measures such as providing bicycle parking, access to public transit, and infrastructure that supports alternative transportation modes. These strategies help reduce the reliance on singleoccupancy vehicles, which is a significant source of GHG emissions.

5. Waste Reduction: Developers are encouraged to implement practices that minimize waste generation during construction and encourage recycling and reuse of materials. This not only reduces the environmental footprint of the project but also supports the city’s waste management goals.

6. Green Building Standards: The checklist may include recommendations or requirements for adhering to green building certifications, such as LEED (Leadership in Energy and Environmental Design). These standards provide a framework for designing and constructing buildings that are environmentally responsible and resource-efficient.

The CAP New Development Checklist is intended to guide developers in making environmentally conscious decisions and to ensure that new projects contribute positively to the city’s climate goals.

By providing clear guidelines and expectations, the checklist helps streamline the development review process and promotes consistency in how new developments are assessed for their climate impacts.

Moreover, the checklist supports the city’s broader climate action strategy by integrating sustainability into the early stages of project planning and design. This proactive approach helps Del Valle Restaurant Drive-Thru Addition

to embed GHG reduction measures into new developments, ultimately contributing to the city's overall emissions reduction targets.

In summary, Appendix E of the Santa Rosa 2012 Climate Action Plan, with its focus on the CAP New Development Checklist, plays a crucial role in guiding new development projects toward sustainability. By outlining specific criteria and best practices, the checklist ensures that new developments align with the city’s climate action goals, contributing to a more sustainable and resilient urban environment.

The air quality project-level thresholds of significance were adopted by the Air District’s Board of Directors on June 2, 2010. * The Air District recommends construction projects that require less than 1 year to complete; lead agencies should annualize impacts over the scope of actual days that peak impacts would occur rather than over the full year. Additionally, for phased projects that results in concurrent construction and operational emissions. Construction-related exhaust emissions should be combined with operational emissions for all phases where construction and operations overlap.
** PM10/PM2.5 (fugitive dust) is also recognized to impact local communities. The Air District strongly recommends implementing all feasible fugitive dust management practices especially when construction projects are located near sensitive communities, including schools, residential areas, or other sensitive land uses. These measures are detailed in Chapter 5, Section 5.2.2 Construction-Related Criteria Air Pollutant Emissions.

QUANTIFICATION METHODOLOGY
The construction and operation analyses were performed using the California Emissions Estimation Model® (CalEEMod) version 2022.1.1.28, the official statewide land use computer model designed to provide a uniform platform for estimating potential criteria pollutant and GHG emissions associated with both construction and operations of land use projects under CEQA. The model quantifies direct emissions from construction and operations (including vehicle use), as well as indirect emissions, such as GHG emissions from energy use, solid waste disposal, vegetation planting and/or removal, and water use. The mobile source emission factors used in the model – published by the California Air Resources Board (CARB) – include the Pavley standards and Low Carbon Fuel standards. The model also identifies project design features, regulatory measures, and Del Valle Restaurant Drive-Thru Addition

control measures to reduce criteria pollutant and GHG emissions along with calculating the benefits achieved from the selected measures. CalEEMod was developed by the California Air Pollution Control Officers Association (CAPCOA) in collaboration with the South Coast Air Quality Management District (SCAQMD), BAAQMD, the San Joaquin Valley Air Pollution Control District (SJVAPCD), and other California air districts. Default land use data (e.g., emission factors, trip lengths, meteorology, source inventory, etc.) were provided by the various California air districts to account for local requirements and conditions. As the official assessment methodology for land use projects in California, CalEEMod is relied upon herein for construction and operational emissions quantification, which forms the basis for the impact analysis.

ASSUMPTIONS
The following basic assumptions were used in developing the emission estimates for the proposed Project using CalEEMod:
 Project design features including parcel dimensions, grading quantities, parking spaces, and sizes of the proposed facility were defined by the Applicant.  Default construction equipment horsepower ratings and load factors contained in CalEEMod were applied to all phases of the project.
 Consumer product usage for maintenance during project operation are CalEEMod defaults.  Energy efficiency and water conservation measures are generally required by codes.  Use of low- reactive organic gases (ROG) architectural coatings (rule-compliant).

The CalEEMod output files for this analysis are contained in Attachment 1.

AIR QUALITY IMPACT ANALYSIS
The Project would result in air pollutant emissions from both the construction and operations phases. These emissions are evaluated against the CEQA significance thresholds adopted by the BAAQMD.

Criteria Pollutants from Project Construction
A project’s construction phase produces many types of emissions. Fugitive dust emissions can result from a variety of construction activities, including excavation, grading, demolition, vehicle travel on paved and unpaved surfaces, and vehicle exhaust. Construction-related emissions can cause substantial increases in localized concentrations of PM10, as well as affecting PM10 compliance with ambient air quality standards on a regional basis. Particulate emissions from construction activities can lead to adverse health effects as well as nuisance concerns such as reduced visibility and soiling of exposed surfaces. The use of diesel-powered construction equipment emits ozone precursors oxides of nitrogen (NOx) and reactive organic gases (ROG), and diesel particulate matter (DPM), the latter being a composite of TACs containing a variety of hazardous substances. Large construction projects using multiple large earthmoving equipment are evaluated to determine if operations may exceed the District’s daily threshold for NOx emissions and could temporarily expose area residents to hazardous levels of DPM. Use of architectural coatings and other materials associated with finishing buildings may also emit ROG and TACs.

CEQA significance thresholds address the impacts of construction activity emissions on local and Del Valle Restaurant Drive-Thru Addition

regional air quality. Thresholds are also provided for other potential impacts related to project construction, such as odors and TACs.

The BAAQMD’s approach to CEQA analyses of fugitive dust impacts is to require implementation of effective and comprehensive dust control measures rather than to require detailed quantification of emissions. PM10 emitted during construction can vary greatly depending on the level of activity, the specific operations taking place, the equipment being operated, local soils, weather conditions, and other factors, making quantification difficult. Despite this variability in emissions, experience has shown that there are several feasible control measures that can be reasonably implemented to significantly reduce fugitive dust emissions from construction. For larger projects, the BAAQMD has determined that compliance with an approved fugitive dust control plan comprising Best Management Practices (BMPs), primarily through frequent water application, constitutes sufficient control to limit PM10 impacts to a level considered less than significant.

Table 3 shows the air pollutant emissions attributable to the Project and evaluates the emissions against BAAQMD significance thresholds. As shown in this Table, Project related emissions are less than the significance thresholds adopted by the BAAQMD. As such, the Project would not result in excessive levels of regional criteria pollutants for the construction phase.

Criteria Pollutants from Project Operation
The term “project operations” refers to the full range of activities that can or may generate criteria pollutant, GHG, and TAC emissions when the project is functioning in its intended use. For projects such as office parks, shopping centers, apartment buildings, residential subdivisions, hotels, and other indirect sources, motor vehicles traveling to and from the project represents the primary source of air pollutant emissions. For industrial projects and some commercial projects, equipment operation and manufacturing processes, i.e., permitted stationary sources, can be of greatest concern from an emissions standpoint. CEQA significance thresholds address the impacts of operational emission sources on local and regional air quality. Thresholds are also provided for other potential impacts related to project operations, such as odors.

Table 5 shows criteria operational emissions associated with the Project and evaluates these emissions against BAAQMD significance thresholds. As shown in this Table, the operations phase of the Project would result in emissions which are less than the significance thresholds adopted by the BAAQMD for the operations phase. Consequently, the project would result in less than significant impacts from operations phase emissions.

Total PM2.5 0.3 54 0.5% No
Sources: BAAQMD 2022, CalEEMod version 2022.1.1.28
Notes:
lbs/day are daily average for planned land use
Total PM10 / PM2.5 comprises fugitive dust plus engine exhaust The operations phase of the Project would also result in vehicle queues at the proposed drivethrough. The Project’s Preliminary Focused Transportation Study for the Del Valle Restaurant Expansion Project (W-Trans 2022) estimates that for “Option D” there would be an additional 27 AM peak hour trips and 64 PM peak hour trips. The CalEEMod computer model estimates that there would be approximately 420 Average Daily Trips (ADT) on a weekly basis1 . These vehicle
trips would result in both travel and idling emissions. Traffic volumes provided within the City’s traffic counts (Santa Rosa 2019) show that Sebastopol Road west of Stony Point Road has over 18,000 ADT. At 420 ADT, the Project would represent about a 2.3% increase in daily traffic on Sebastopol Road. These emissions would not result in elevated concentrations of pollutants beyond the National and California ambient air quality standards due to the relatively small number of additional vehicles as well as the low emission rates associated with vehicles that are required to have catalytic converters. In addition, the State of California is in a state of attainment of ambient carbon monoxide concentrations emitted from roadway vehicles for more than two decades.

Construction and operational emissions from the proposed Project would not exceed the applicable thresholds. Further, construction emissions would permanently cease upon completion of the new facilities. Any proposed project that would individually have a significant air quality impact would also be considered to have a significant cumulative air quality impact. Therefore, because temporary construction emissions and projected changes in operational emissions would be less than significant, the resultant air quality impact is not considered by the BAAQMD to be cumulatively considerable and would result in a less than significant cumulative impact.

IMPACT: Less Than Significant
1 CalEEMod was used to estimate the 7-day weighted average daily trip rates (Weekdays, Saturdays, Sundays).

Notes:

Project Total comprises annual operational emissions plus construction emissions amortized over 30 years As mentioned above, the City of Santa Rosa has adopted a qualified CAP in 2012 to address the effects of climate change and minimize greenhouse gas emissions within the City. Through this framework, the Air District has identified key design elements that new land use projects and plans must incorporate to meet California's goal of carbon neutrality by 2045. When these elements are included in a project’s design and construction, the project fulfills its fair share of necessary reductions, allowing the lead agency to conclude that it does not significantly contribute to global climate change when evaluated under CEQA. As previously shown in Table 2, the BAAQMD’s Climate Impact Thresholds allows for projects to either include building and transportation design elements, which reduce GHG emissions, or projects must be consistent with a local GHG reduction strategy that meets the criteria under State CEQA Guidelines Section 15183.5(b). The City of Santa Rosa’s CAP meets the programmatic threshold of the BAAQMD guidelines.

The City of Santa Rosa has accounted for the City’s fair share of emissions within CAP. “To ensure new development projects are compliant with the City’s Climate Action Plan, the following checklist has been developed. This checklist should be filled out for each new project, subject to discretionary review, to allow new development to find a less than significant impact for greenhouse gas emissions in the environmental review process.” (City 2012). The project developer has filled out the CAP New Development Checklist and demonstrated consistency with the GHG reduction goals adopted by the City. Therefore, the Project would not directly or indirectly generate GHG emissions that would have a significant impact on the environment and the projected impact would be less than significant and no additional control measures would be required (BAAQMD 2022). The CAP New Development Checklist for the proposed Project can be found in Attachment 2.

IMPACT: 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 11.9 annual days of extreme heat Extreme Precipitation 11.2 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 6.06 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 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.
