3.1.1. Underserved Population
The 2023 California State Hazard Mitigation Plan identifies the Centers for Disease Control and Prevention (CDC) Social Vulnerability Index (SVI) as the most appropriate and authoritative dataset to identify areas where efforts can be prioritized to ensure equitable outcomes from mitigation planning and actions.

CDC’s SVI combines 16 social factors, within four (4) themes (i.e., socioeconomic status, household characteristics, racial and ethnic minority status, and housing type and transportation), to identify areas of social vulnerability. Table 3 outlines the SVI information for the City of San Pablo.

Note: ArcGIS mapping analysis was performed utilizing Census Tract data by overlaying Census Tracts with the City of San Pablo planning area boundary. The information outlined in this section includes data from the Census Tracts that intersect the jurisdiction.

3.2. Brief History
The Ohlone (also known as Costanoan) Indians resided in the Bay Area, living in villages along the East Bay of San Francisco for thousands of years. One (1) village, between the two (2) creeks now named Wildcat and San Pablo, is the site of what is now known as the City of San Pablo. Food was plentiful with two (2) creeks providing fresh water, nourishing plants, and attracting animals, and the Bay was a source of fish and shellfish. In the late 1700s, the Spanish government in Mexico sent explorers into the area, followed by missionaries and settlers. Mission Dolores in San Francisco was founded in 1776. The ground in the area was not fertile for planting, and by 1815 the Indians had established Rancho San Pablo on the opposite coast of the bay (contra cost a in Spanish) to raise cattle and food for the mission. Rancho San Pablo was the first permanent non- Indian settlement in all of what is now Contra Costa County.

Mexico gained independence from Spain and began to divide up land owned by the missions. The overseer of Rancho San Pablo requested permission to claim the rancho as his own and in 1823, Francisco Castro was granted 17,000 acres of land. The rancho covered land that is now Richmond, El Sobrante, and Pinole, and extended all the way out to what is today called San Pablo Bay.

The Gold Rush and the annexation of California by the United States brought drastic changes to San Pablo. A stage route was established from San Francisco and Oakland to Sacramento and saloons lined the main street, which was wide enough to accommodate the movement of cattle herds. The Castro descendants began to sell off portions of their Rancho to American ranchers and farmers. A Post Office was established, a school was built, and churches were founded. Many of the new ranchers were immigrants to the Uni ted States from Azores Island Portuguese, Chile, Germany, France, China and African Americans lived in the area. It is assumed that a number of Mexicans, such as the Castro’s and Alvarado’s, continued to live in the area. San Pablo was the home of Governor Juan Bautista Alvarado, the first native-born governor of the State of California, who had married one of the Castro daughters.

World War II changed the City of San Pablo into a suburban city. In just a few years, the population boomed from 2,000 to 25,000 people, due to job availability at the Richmond Shipyard. People came from all over the United States to get jobs as welders and many African Americans came from the South and established the first sizable Black community in the area. Housing was built in small lots as quickly as possible to accommodate these new workers. These tiny homes built during the war characterize San Pablo. There were nightclubs and dance halls featuring country bands, including the Lighthouse Inn San Pablo, which contributed to the City’s reputation as a party town. Swing bands were popular among the young shipyard workers and the clubs were often open 24 hours to accommodate all three (3) work shifts at the shipyard. The last dairy ranchers sold out to giant corporations, and the last farmers divided and sold their land for housing tracts.

Post-wartime, the community settled down to raise families. In the 1950s public works projects paved the streets, added sidewalks, and installed streetlights. Furthermore, playgrounds were opened, a hospital was built, Contra Costa College opened, and shopping centers replaced wartime housing.

Today, San Pablo is an innovative city with many community programs. The City has nine (9) facilities available to the community, including a commercial kitchen, and four (4) city-maintained parks with soccer fields, baseball fields, and a senior center. Wildcat Canyon Park and Hilltop Lake Park are in close proximity to the City. I n recent years, the City developed and adopted a bicycle and pedestrian master plan to create an enjoyable place for walking and bicycling. Furthermore, the City is dedicated to protecting the environment through clean water, energy conservation, climate action, and waste recycling programs. San Pablo conserves natural resources by providing programs and resources to reduce waste, recycle products that can be made into new products, and safely dispose of hazardous waste. The City also has a food scrap composting program for residents. 2024 Hazard Mitigation Plan

3.3. Governing Body Format
The City of San Pablo is a General Law City, operating under the City Council/City Manager form of government. Under this form of government, the Council establishes the policies under which the City operates and appoints a trained and experienced City Manager to admi nister City affairs. The City Manager’s responsibilities include hiring of City staff, preparation of the Annual Budget, administration and coordination of the City’s operations, general supervision over all property under the control of the City, and enforcement of City ordinances and applicable State laws.

The City Council is comprised of five (5) members elected at large to overlapping terms of four (4) years and annually select two (2) of their members to serve as Mayor and Vice Mayor. The Mayor represents the City at community functions, serves as the Cit y’s liaison with other governmental agencies, and serves as the presiding officer at council meetings.

The Council is the legislative body, and its members are the community’s decision makers. The Council approves the budget and determines the public services to be provided and the taxes, fees, and assessments to pay for these public services. The City Council is responsible for adopting this Plan and the City Manager is responsible for overseeing its implementation.

4. DEVELOPMENT TRENDS
California Law requires counties and cities to prepare and adopt a General Pan, a comprehensive long- range plan to guide community development. The General Plan must contain seven (7) state-mandated elements – land use, housing, circulation, safety, open space, conservation, and noise – and may contain additional elements as a jurisdiction sees fit. Additionally, the General Plan must comprise an integrated and internally consistent set of goals, policies, and implementation measures. The City of San Pablo adopted its General Plan under this law and has updated it several times over the years, including most recently in April 2011.

San Pablo is a highly urbanized City within its 2.8 square miles planning area, which includes the corporate limits and adjacent unincorporated areas in Rollingwood and Hasford Heights. The existing City limits include residential, commercial, and industri al developments, as well as public facilities, including parks and schools. San Pablo’s Economic Development Program is administered through the San Pablo Economic Development Corporation, has short and long range economic development strategies to encourage the growth of new businesses, attraction of new business, enhancement of existing businesses as well as the creation and retention of jobs. According to California Department of Finance estimates, San Pablo had a total of 9,941 housing units as of December 2020, which is a 6.8% increase since 2000 when there were 9,307 housing units in San Pablo. Slightly less than half the homes in San Pablo are in single family detached buildings. Another 16% of the households live in large, multi- unit buildings of 20 units or more, while the rest live in smaller multi-unit buildings.

The City has considered the housing needs of seniors, people living with a disability, large families, female headed households, extremely low income households and people, homeless population, and farmworkers. There are 12 affordable housing developments in San Pablo, in which seven (7) provide housing for lower income families and five (5) provide housing for seniors. In total, including all rental assistance vouchers, there are 901 subsidized households/housing units in San Pablo, which represents 10% of the households in the City. Other methods of assistance include (subsidized) rents, handicapped accessible homes, and buildings near public transportation. The City has also conducted an assessment to identify vacant sites for possible housing development.

City of San Pablo Annex 5
During the 2010 to 2020 period, San Pablo saw very little housing development activity and moderate commercial improvements. Since 2020, development activity has increased with several pipeline housing and commercial projects. With a few exceptions, this development has represented redevelopment of previously developed sites. These development changes have not affected the jurisdiction’s overall vulnerability in the last five (5) years.

Table 4 summarizes development trends in the performance period since development of the previous hazard mitigation plan and expected future development trends.

Other than development regulated by the City’s Flood Damage Prevention Ordinance, the City does not track development by hazard zones. The City cites development restrictions on a case- by-case basis.

4.1. Changes in Priority
The overall hazard mitigation priorities have not significantly changed for the City of San Pablo since the last Plan update. However, mitigation actions from the previous Plan were updated, and a more concerted 2024 Hazard Mitigation Plan
Contra Costa County, California

City of San Pablo Annex 6
effort on achieving equitable outcomes for all communities, including underserved communities and socially vulnerable populations, has been implemented.

5. CAPABILITY ASSESSMENT
Federal regulations require hazard mitigation plans to identify goals for reducing long-term vulnerabilities to the identified hazards in the planning area (Section 201.6(c)(3)(i)). A critical step in the development of specific hazard mitigation actions and projects is assessing existing authorities, policies, program s, and resources and capabilities to use or modify local tools to reduce losses and vulnerability from profiled hazards.

A capability assessment was conducted for the City of San Pablo and participating jurisdictions’ authorities, policies, programs, and resources. Goals and mitigation actions were developed using input from this assessment. Information regarding the City’s implementation of and continued participation in the National Flood Insurance Program (NFIP) can be found in Section 8 of this Annex.

The Local Planning Team assessed the City’s capabilities that can contribute to the reduction of long- term vulnerabilities to hazards. The capabilities include the following categories:

• Planning and Regulatory Capabilities
• Administrative and Technical Capabilities
• Financial Capabilities
• Education and Outreach Capabilities

Additionally, ways to expand on and improve these existing policies and programs to integrate hazard mitigation into the day-to-day activities and programs of the City were considered.

5.1. Planning and Regulatory Capabilities
These include local ordinances, policies, and laws to manage growth and development (e.g., land use plans, capital improvement plans, transportation plans, emergency preparedness and response plans, building codes, and zoning ordinances ). The City of San Pablo will adopt the approved 2024 Contra Costa County Hazard Mitigation Plan into the City’s General Plan Safety Element for AB 2140 compliance. Table 5 contains a list of legal and regulatory capabilities. The d escription section of each Planning and Regulatory Capability includes a paragraph on expansion, implementation, and improvement.

6. HAZARD MITIGATION PLAN INTEGRATION
The information on hazards, risk, vulnerability, and mitigation contained in this Hazard Mitigation Plan is based on the best available data at the time of the Plan update. Plan integration consists of the incorporation of hazard mitigation into other relevant planning mechanisms (e.g., general planning and capital improvement planning). It includes the integration of natural hazard information and mitigation policies, principles, and actions into local planning mechanisms and vice versa. Additionally, plan integration is achieved though the involvement of key staff and community officials in collaborative hazard mitigation planning. This section describes the City’s process for integrating information from this Hazard Mitigation Plan into other planning mechanisms.

6.1. Past Plan Integration
In the performance period since the adoption of the previous Hazard Mitigation Plan, City of San Pablo made progress on integrating components of the hazard mitigation strategy (e.g., goals, objectives, and actions) into the planning initiatives listed in Table 9.

Table 9. Past Plan Integration
Planning Initiative Description
City General Plan
The City’s General Plan references and incorporated hazards risk information from this Hazard Mitigation Plan which guides development within the City of San Pablo.

Building and Construction
Code
Mitigation actions and the hazard risk assessment in this Hazard Mitigation Plan can inform updates and revisions to the Building and Construction Code (Title 15, Chapter15-28).

The City’s adoption of the 2022 California Building and Fire codes incorporated local modifications to account for the climatic, topographic, and geographic conditions that exist in the City. Specifically, the adopted C ode reflects risks related to seismicity and soils, as well as the City’s risk of drought and wildfire.

As a result of these specific conditions, the approved code in 2016 modified the State Code by adding more restrictions for concrete foundations and gypsum wallboard to better withstand earthquakes by requiring fire treatment for wood shakes or shingles, installation of a smoke detector when flat roofs are pitched, and electric vehicle charging stations for multifamily and non- residential buildings. Additional changes added in 2022 included
adoption of the 2021
International Property Maintenance Code
Community Rating System
Program
Portions of the County Hazard Mitigation Plan support the o ngoing public outreach and education conducted on flood risk, as part of the City’s participation in the Community Rating System (CRS) Program.

Storm Drain Maintenance
Plan
Flood vulnerability and risk information has been enhanced by conducting studies and surveys of “hot spots” to help develop City projects and improve efficiency. This Hazard Mitigation Plan has been referenced for the studies and surveys. Additionally, the City has a storm drain systems (e.g., pipes, ditches, swales, etc.) maintenance program designed to ensure maximum capacity and mitigate flooding. Mitigation actions in this Hazard Mitigation Plan can inform updates and revisions to the Storm Drain Maintenance Plan.

Public Utility Agencies
Coordination
City of San Pablo coordinates with other public utility agencies to gain knowledge from each agency’s hazard mitigation projects and new system developments to better prepare in an event of a flood.
2024 Hazard Mitigation Plan
Contra Costa County, California

City of San Pablo Annex 17
Planning Initiative Description
Public Outreach Program
City staff provides information based on the Hazard Mitigation Plan to real estate agents and property owners related to flood, wildfire, earthquake, and landslide hazard zones. Additionally, information on sandbag locations is provided in the City newsletter and website to residents.

Construction Measures
Portions of th e Hazard Mitigation Plan with the associated mapping were considered when enhancing the City’s construction measures. The City ensures that erosion and stormwater control measures are in place for construction activities prior to and during rainfall events. Additionally, annual inspections and documentation of construction sites occur prior to the rainy season. Due to the geologic formation of the area, geotechnical reports are required for new home construction, most remodels, and new development projects.

6.2. Potential Future Integration
As the Hazard Mitigation Plan is implemented, the City of San Pablo will use information from the Plan as the best available science and data on hazards. The capability assessment presented in Section 5 of this Annex identifies codes, plans, and programs that provide opportunities for integration. The Citywide and local action plans developed for this Hazard Mitigation Plan are related to plan integration. The capability assessment identified plans and programs, listed in Table 10, that do not currently integrate goals and recommendations of this Plan but provide opportunities to do so in the future.

Table 10. Potential Future Integration
Planning Initiative Description
City General Plan
Future update s to the City’s General Plan pursuant to the requirements of Senate Bill 379 will refer to this Hazard Mitigation Plan and incorporate, as appropriate, hazard mitigation related to flood control, urban watershed management, habitat conservation, and growth control.

Community Rating System
Program
The City will request credit for this Hazard Mitigation Plan under future CRS Program verification audits and is committed to maintaining this Plan pursuant to the Plan Maintenance strategy identified in Volume 1 of this Plan.

City Climate Action Plan
Future updates to the City’s Climate Action Plan will refer to this Hazard Mitigation Plan for appropriate information on risk associated with natural hazards to inform climate action policies and programs.

Storm Drain Development
and Modeling Plan
Upon completion, grant eligible projects identified by the Storm Drain Development and Modeling Plan will be incorporated into this Hazard Mitigation Plan.

The City’s Local Planning Team will identify all relevant planning initiatives that are scheduled to be updated in the next year and during the annual update process of the Hazard Mitigation Plan. Additionally, opportunities to integrate key elements of the Hazard Mitigation Plan, specifically any relevant strategies, into the planning initiatives will be identified by the Local Planning Team. Mitigation actions were identified to promote plan integration in future revisions of this Plan.

8.2.1. Substantial Damage and Substantial Improvement Determination Applications for building permits to improve structures, including alterations, movement, repair, additions, rehabilitations, renovations, substantial improvements, repairs of substantial damage, and any other improvement of or work on such structures that occurs within a 10-year cumulative period, the floodplain administrator, in coordination with the building official, must:

• Estimate the market value or require the applicant to obtain a professional appraisal prepared by a qualified independent appraiser of the market value of the structure before the start of construction of the proposed work . In the case of repair, the market value of the building or structure shall be the market value before the damage occurred and before any repairs are made. • Compare the cost to perform the improvement, the cost to repair the damaged building to its pre- damaged condition, or the combined costs of improvements and repairs, where applicable, to the market value of the structure.
2024 Hazard Mitigation Plan
Contra Costa County, California

City of San Pablo Annex 19
• Determine and document whether the proposed work constitutes substantial improvement or repair of substantial damage.
• Notify the applicant when it is determined that the work constitutes substantial improvement or repair of substantial damage and that compliance with the flood resistant construction requirements of the building code is required and notify the applicant when it is determined that work does not constitute substantial improvement or repair of substantial damage. (Municipal Code Title 15, Chapter 15.28 – Floodplain Management and Flood Damage Prevention)

8.3. Repetitive Loss and Severe Repetitive Loss Properties The Federal Emergency Management Agency (FEMA) defines a Repetitive Loss property as an NFIP insured structure with two (2) or more claims of more than $1,000 each within any rolling 10-year period, since 1978.2

A Severe Repetitive Loss property is defined by FEMA as any NFIP insured structure for which either of the following is true when at least two (2) of the claims are within 10 years of each other (claims made within 10 days will be counted as one (1) claim):3

• That has incurred flood related damage for which four (4) or more separate claims payments have been made, with the amount of each claim (including buildings and contents payments) exceeding $5,000, and with the cumulative amount of such claims exceeding $20,000. • For which at least two (2) separate claims payments (building payments only) have been made under such coverage, with the cumulative amount of such claims exceeding the market value of the building.

Repetitive loss records from the City of San Pablo are listed in Table 13.

9. H AZARD VULNERABILITY AND IMPACT ASSESSMENT
Exposure and vulnerability to certain hazards affect the entire County and others are geographically defined. Although the entire County may be vulnerable to these hazards, their impacts may vary based on existing community conditions (e.g., underserved, or functional access needs populations may be more susceptible based on certain conditions, vulnerabilities, or needs).

The Local Planning Team identified unique vulnerabilities and impacts to the following natural hazards, based on the hazards profiled in Volume 1 (Planning Area-wide Elements).

• Dam and Levee Failure
• Earthquake

• Flood (riverine/creek, urban/flash flood)
• Landslide
• Severe Weather (heavy rainfall, severe thunderstorms, strong winds/damaging winds, heat wave/extreme heat, tornado)
• Wildfire

It was determined that the planning area did not have unique vulnerabilities and impacts to the following natural hazards; rather, its vulnerability and impacts are consistent with those experienced throughout the County.

• Climate Change
• Drought
• Sea Level Rise
• Tsunami

Note: Severe weather and flooding are profiled as the two (2) hazards. However, in an effort to have a more thorough risk assessment, the sub hazards (i.e., heavy rainfall, severe thunderstorms, strong winds/damaging winds, heat wave/extreme heat, tornado, riverine/creek flooding, and urban/flash flooding) were ranked individually. The hazard risk assessment methodology can be found in Appendix C of this Annex.

Table 14 provides information on several key vulnerabilities and impacts for the City of San Pablo and only addresses the hazards that are relevant and unique to the jurisdiction. A complete risk assessment for each identified hazard of concern is in Volume 1 (Planning Area-wide Elements) of this Plan. Hazard mapping can be found in Appendix A of this Annex.

Table 14. Hazard Vulnerability and Impact Assessment
Hazards Vulnerabilities and Impacts
Climate Change
The Local Planning Team determined that the City does not have unique vulnerabilities and impacts to climate change; rather, the City’s vulnerability and impacts are consistent with those experienced throughout the County.

Dam and Levee Failure
The City of San Pablo is downstream of the San Pablo Dam and in the event of a dam failure, much of the City would be affected.

According to the East Bay Municipal Utility District (EBMUD) Summit Reservoir Replacement Project , 51 miles of roadway and almost all schools and government buildings within the City would be inundated in the event of a dam failure. Additionally, numerous vulnerable populations would be impacted, including at least four (4) mobile home parks, a supportive housing facility, and multiple senior housing complexes that may be inundated in the event of a dam failure. Low -income populations in the area may not have the resources to evacuate or prepare their properties for water rise prior to evacuation and may face greater financial barriers to rebuilding post -disaster. The flood insurance required for this type of disaster may increase the financial burden on low - income families that may be affected by this type of disaster.

Drought
The Local Planning Team determined that the City does not have unique vulnerabilities and impacts to droughts ; rather, the City’s vulnerability and impacts are consistent with those experienced throughout the County. 2024 Hazard Mitigation Plan
Contra Costa County, California

City of San Pablo Annex 21
Hazards Vulnerabilities and Impacts
Earthquake
The North Hayward Fault Zone passes directly underneath the eastern portion of the C ity and is considered a high earthquake hazard because any large movements would cause ground shaking and surface rupture in the area.

Impacts would be especially acute in areas directly over the fault line, including vulnerable low-income populations in the 34-unit Frontier Mobile Home Park and 141 units of public housing in the Kidd Manor and Vista del Camino housing projects. Additiona
lly, the North Hayward Fault runs through Contra Costa
College, where at least seven (7) academic and support buildings are outside of the habitable structure zone in the event of an earthquake. Homes in the hillside area on the east side of I nterstate 80 and in the Leona Heights neighborhood would likely be acutely affected by ground movement and landslides in the area.

Furthermore, portions of the C ity are at risk for liquefaction, which can cause further damage to homes and businesses in low -lying areas near the C ity’s creeks. Altogether, the potential damages from earthquakes would have significant Citywide impacts on low-income residents, who may struggle to bear the financial burden of repairing damage to their property and belongings , and may struggle to find alternative sources of basic necessities in the event that utility grids and supply chains are disrupted from an earthquake.

Flood
(urban/flash flood, riverine/creek)
Areas along the San Pablo Creek and Wildcat Creek are in 0.2% or 1% annual flood hazard zones, as well as nearby low -lying areas. Vulnerable structures in these areas include the San Pablo Senior Center, the San Pablo First Five Center, the Creekside nursing home, two (2) grocery stores, a post office, and hundreds of single-family homes, multifamily units, and businesses. Most of the impacted residential areas are low-income, Hispanic-majority neighborhoods.

Additionally, t he following intersections have experienced repeated flooding issues:

• Market Avenue and Rumrill Boulevard
• Market Avenue and 21st Street
• Sanford Avenue (west of Rumrill Boulevard)
• Manor Drive and Rumrill Boulevard
• Sutter Avenue (between 16th Street and Rumrill Boulevard) • 19th Street and Rivers Street
• Regina Avenue and Rumrill Boulevard
• 17th Street and Dover Avenue

All of the above intersections are located in areas with low socioeconomic conditions, and severe flooding at these locations may impact single- family homes and small multifamily buildings, as well as neighborhood-serving grocery stores and small businesses in the vicinity.

Landslides
Hillside areas east of Interstate 80 have known landslide risks and a history of slide activity, on both developed and undeveloped parcels. A number of single- family homes, particularly in the vicinity of Hillcrest Drive, several multifamily complexes, the Frontier Mobile Home Park, and the Princeton Plaza shopping center are in areas of particularly high landslide risk. Vulnerable populations in low-income groups residing in the mobile home park and apartment complexes may be uniquely impacted in the event of a landslide.

Sea Level Rise
The Local Planning Team determined that the City does not have unique vulnerabilities and impacts to sea level rise; rather, the City’s vulnerability and impacts are consistent with those experienced throughout the County. 2024 Hazard Mitigation Plan
Contra Costa County, California

City of San Pablo Annex 22
Hazards Vulnerabilities and Impacts
Severe Weather
(heavy rainfall, severe
thunderstorms, strong
winds/damaging winds, heat
wave/extreme heat, tornado)
A portion of the City is within a flood zone, including many older buildings in low- income neighborhoods, and several intersections are known to flood during heavy rainfall events. Additionally, the City has seven (7) manufactured home communities, which house vulnerable low -income populations and are particularly vulnerable to severe weather , as strong winds/damaging winds , heavy rainfall , and flooding may damage mobile homes more easily than a traditionally built home.

Additionally, the effects of heat wave/extreme heat events will be more acute in San Pablo due to the lack of green space and street trees in many of the City’s densest low-income neighborhoods (i.e., urban heat island effect). Low-income communities may lack access to air conditioning, alternative water sources, and other extreme hea t proofing
measures, and they may have greater difficulty
managing increased costs of essentials (e.g., water and electricity ) that may result during a heat wave/extreme heat event . This population may have more difficulty accessing cooling centers and live in areas more vulnerable to extreme heat. This lack of access to resources and increased likelihood of exposure to extreme heat and other climate- related disasters
makes these communities,
who are prevalent in San Pablo, uniquely vulnerable to the impacts of extreme heat events.

Tsunami
The Local Planning Team determined that the City does not have unique vulnerabilities and impacts to tsunamis; rather, the City’s vulnerability and impacts are consistent with those experienced throughout the County.

Wildfire
Hillside areas east of Interstate 80 are at the edges of wildfire risk areas, and further areas may be vulnerable due to the unpredictable nature of wildfires.

While no structures are identified as being within high wildfire risk zones, areas on the east side of Interstate 80, including numerous single- family homes,
apartment complexes, and the commercial strip on San Pablo Dam Road (i.e., Princeton Plaza and Sobrante Plaza shopping centers ) may be particularly at risk due to their proximity to the wildfire risk zone and undeveloped hillside areas.

Active Shooter Incidents
The Local Planning Team determined that the City does not have unique vulnerabilities and impacts to active shooter incidents ; rather, the City’s vulnerability and impacts are consistent with those experienced throughout the County.

Cybersecurity Threats
The Local Planning Team determined that the City does not have unique vulnerabilities and impacts to cybersecurity threats ; rather, the City’s vulnerability and impacts are consistent with those experienced throughout the County.

Hazardous Materials
Incidents
San Pablo is located near several heavy industrial uses in neighboring Richmond, including the Richmond Refinery. A hazardous materials incident in these areas would likely affect San Pablo due to their proximity. Truck routes and train tracks that bring traffic and cargo to and from these industrial areas run close to the residential areas in the City,
compounding the risk of a
hazardous materials incident that could affect the City.

Terrorism (Weapons of
Mass Destruction)
The Local Planning Team determined that the City does not have unique vulnerabilities and impacts to terrorism ; rather, the City’s vulnerability and impacts are consistent with those experienced throughout the County.

Utility Interruptions
The Local Planning Team determined that the City does not have unique vulnerabilities and impacts to utility interruptions ; rather, the City’s vulnerability and impacts are consistent with those experienced throughout the County.

2024 Hazard Mitigation Plan
Contra Costa County, California

City of San Pablo Annex 23
The City evaluated whether vulnerability and impact in hazard prone areas had increased, decreased, or remained the same for each natural hazard identified in this Hazard Mitigation Plan. Climate change, changes in population, infrastructure expansion, and economic shifts that can affect vulnerability were considered. For example, if planned development is in an identified hazard areas or is not built to the updated building codes, it may increase the community’s vulnerability to future hazards and disaster s.

On the other hand, if development occurred with mitigation practices in place, the vulnerability may have remained the same or decreased. Additionally, shifting demographics (e.g., underserved population) were taken into consideration.

Table 15 outlines if climate change has increased or decreased the City’s vulnerability (i.e., exposure) and impact to each natural hazard over the past five (5) years, and the effect of climate change in the future probability of occurrence and impacts from each natural hazard.

See Table 4 for anticipated future major assets that may be exposed or vulnerable to any of the natural hazards identified in this Hazard Mitigation Plan. Any new assets (e.g., new construction in hazard prone areas) will be constructed to adhere to the latest building codes and standards, and mitigation to protect them from identified and anticipated hazards, especially those that are expected to increase due to climate change.

Refer to Appendix C and Appendix D of this Annex for the hazard risk assessment methodology and jurisdiction specific details, which includes the vulnerability and impacts to population and life safety, underserved/equity, property damage, future development, and climate change.

9.1. FEMA National Risk Index
In the National Risk Index (NRI), risk is defined as the potential for negative impacts as a result of a natural hazard. The Risk Index is based on three (3) components – a natural hazards component (Expected Annual Loss), a consequence enhancing component (Social Vulnerability), and a consequence reduction component (Community Resilience). Using these components, the composite and hazard type Risk Index values are calculated for each community (county and Census Tract). Risk 2024 Hazard Mitigation Plan
Contra Costa County, California

City of San Pablo Annex 26
Index values form an absolute basis for measuring Risk within the NRI and are used to generate Risk Index percentiles and ratings across communities.4 Table 18 illustrates the Risk Index rating and score for the City of San Pablo.

Note: ArcGIS mapping analysis was performed utilizing Census Tract data by overlaying Census Tracts with the City of San Pablo planning area boundary. The information outlined in this section includes data from the Census Tracts that intersect the jurisdiction.

Table 18. Risk Index Score (FEMA National Risk Index)
Jurisdiction Rating Score
City of San Pablo Very High 90.2
Risk Index scores are calculated using an equation that combines scores for Expected Annual Loss due to natural hazards, Social Vulnerability and Community Resilience (Expected Annual Loss x Social Vulnerability / Community Resilience = Risk Index).

9.1.1. Expected Annual Loss
The FEMA NRI Expected Annual Loss (EAL), the natural hazards component of the NRI, represents the average economic loss in dollars resulting from natural hazards each year. It is calculated for each hazard type and quantifies loss for relevant consequence types – buildings, people, and agriculture. The EAL score and rating represent a community's relative level of expected losses each year when compared to all other communities at the same level. Since the score is associated to a community’s risk; the higher EAL score results in a higher Risk Index score.5 Table 19 illustrates each hazard EAL for the City of San Pablo.

Expected annual loss scores are calculated utilizing an equation that combines values for exposure, annualized frequency, and historic loss ratios (Expected Annual Loss = Exposure x Annualized Frequency x Historic Loss Ratio).

An EAL score and rating is calculated independently for each consequence type (i.e., buildings, population, and agriculture) for each county and Census Tract. The population EAL is measured in fatalities and injuries while the building and agriculture values are measured in dollars. However, for consistency in the unit of measurement, the population EAL was monetized into population equivalence using a value of statistical life (VSL) approach where each fatality or 10 injuries is treated as $11.6 Million of economic loss.

9.1.2. Social Vulnerability
Social vulnerability, the consequence enhancing risk component of the NRI, measures the susceptibility of social groups to the adverse impacts of natural hazards, including disproportionate death, injury, loss, or disruption of livelihood. The Social Vulnerability score and rating represent the relative level of a community’s social vulnerability compared to all other communities at the same level. A higher Social Vulnerability score results in a higher Risk Index score. 6 Table 20 illustrates the Social Vulnerability rating
and score for City of San Pablo.

Table 20. Social Vulnerability (FEMA National Risk Index) Jurisdiction Rating Score
City of San Pablo Very High 84.0
Social Vulnerability is measured using the Social Vulnerability Index (SoVI) published by the University of South Carolina’s Hazards and Vulnerability Research Institute (HVRI).

9.1.3. Community Resilience
Community resilience, the consequence reduction risk component, measures the ability of a community to prepare for anticipated natural hazards, adapt to changing conditions, and withstand and recover rapidly from disruptions. The Community Resilience score and rating represent the relative level of a community’s resilience compared to all other communities at the same level. Since the score is inversely

proportional to a community’s risk; the higher Community Resilience score results in a lower Risk Index score.7 Table 21 illustrates the Community Resilience rating and score for the City of San Pablo.

Table 21. Community Resilience (FEMA National Risk Index) Jurisdiction Rating Score
City of San Pablo Relatively High 66.4
Community Resilience is measured using the Baseline Resilience Indicators for Communities (HVRI BRIC) published by the University of South Carolina's Hazards and Vulnerability Research Institute (HVRI).

9.1.4. Annualized Frequency
Annualized frequency is defined as the expected frequency or probability of a hazard occurrence per year. It is a natural hazard incidence factor for Expected Annual Loss, the natural hazards component of the National Risk Index. A higher annualized frequency value results in higher Expected Annual Loss and Risk Index scores. The annualized frequency is derived from either the number of recorded hazard occurrences each year over a given period or the modeled probability of a hazard occurrence each year (e.g., earthquake).
8 Table 22 outlines the annualized frequency for each hazard, based on FEMA NRI data, for the City of San Pablo.

of this Annex , the ranking process involves an assessment of the likelihood of occurrence for each hazard, along with its potential impacts on people, property, and the economy. For further details on how the probability, extent, vulnerability, and impact factors in Table 23 were calculated, please refer to Appendix D of this Annex.

It is important to note that the sub hazards for severe weather hazards (i.e., heavy rainfall, severe thunderstorms, strong winds/damaging winds, heat wave/extreme heat, and tornado) and flood hazards (i.e., riverine/creek flooding and urban/flash flooding) were individually ranked in the hazard risk ranking; however, flood and severe weather are each considered as the main hazard throughout this Annex and Volume 1 (Planning Area-wide Elements).

11. MITIGATION ACTIONS
This section includes the mitigation actions that were developed to address identified risks and vulnerabilities to hazards identified in this Plan. This Plan serves only to recommend mitigation measures based on the potential for risk reduction and available funding. Implementation of mitigation actions is dependent on risk reduction priorities, feasibility, and available funding. It is also dependent on the cooperation and support of the jurisdiction and/or department responsible for each action item.

The City of San Pablo agreed upon 20 mitigation actions that apply to the jurisdiction’s properties where they have jurisdictional responsibility and authority. One (1) mitigation action was completed. A summary of the City’s mitigation actions status is listed in Table 24.

Flood 17 Wildfire 12

These shared actions, some of which address all hazards, help to meet the following requirements:

• Does the Plan identify and analyze a comprehensive range of specific mitigation actions and projects for each jurisdiction being considered to reduce the effects of hazards, with emphasis on new and existing buildings and infrastructure?
• Does the Plan include one (1) or more action(s) per jurisdiction for each hazard identified within the risk assessment?

A detailed explanation of the Mitigation Strategy can be found in Chapter 5 of Volume 1 (Planning Area- wide Elements).

APPENDIX A. HAZARD MAPS
The following hazards were mapped for the City of San Pablo – earthquakes, floods, landslides, and wildfires.

• Figure 1 illustrates the liquefaction susceptibility, which helps assess potential damage from earthquakes in the City.
• Figure 2 illustrates the City of San Pablo Special Flood Hazard Area (SFHZ), including each Flood Zone, and the 500- year floodplain. Flood Insurance Rate Maps (FIRMs) show the flood zones, floodplain boundaries, and Base Floor Elevation (BFE) and are used for floodplain management, flood insurance ratings, and to determine flood insurance requirements. FIRMs show areas with a 1% chance of flooding each year, commonly known as the 100- year floodplains, and are illustrated as the SFHA.
9 The 500-year floodplains show areas with a 0.2%
chance of flooding each year.
• Figure 3 illustrates landslide susceptibility in the City. Landslide susceptibility maps describe the relative likelihood of future land sliding based solely on the intrinsic properties of a location or site.

There are three (3) site factors that most determine susceptibility – prior failure, rock or soil strength, and steepness of slope.10
• Figure 4 illustrates the California Fire Hazard Severity Zones (FHSZ) in the State Responsibility Area (SRA) within the City.

APPENDIX B. STAKEHOLDER AND PUBLIC ENGAGEMENT
The mitigation planning process promotes awareness of hazard risks and continues the conversation about the community’s safety and resilience. A hazard mitigation plan generates additional community support when it accurately reflects the values and priori ties of the community which will lead to successfully implementing the mitigation actions and projects identified in this Plan.

Federal regulations for mitigation plan approval require that stakeholders and the general public are given opportunities to be involved in the plan’s development and update process. Input from community members can strengthen the content and outcomes of the hazard mitigation plan. Furthermore, the Plan must state continued public engagement as the Plan is carried out during its lifetime. A public outreach strategy outlines what the community intends to achieve throughout the outreach efforts. Additionally, it identifies who to involve in the process, and how and when to effectively engage the community. Contra Costa County and the City of San Pablo worked together to ensure that the stakeholder and public engagement was meaningful and productive. Refer to Volume 1 (Planning Area -wide Elements) for further information on how stakeholders and the general public were given opportunities to be involved throughout the planning process. However, every plan participant employed a slightly tailored engagement strategy that suits the community’s demographics, including the underserved population, and needs in addition to the lead jurisdiction’s engagement strategy.

City of San Pablo stakeholders and the public were given a number of opportunities to be involved throughout the planning process. Opportunities were provided via a public survey, in person and virtual public meetings, and public engagement activities to review the Plan draft (i.e., public comment period).

The public meetings allowed the County to introduce the Plan update, identify additional hazards of concern that should be included, if any, and to provide input for the various mitigation measures intended to eliminate or reduce the negative impact to those hazards. Language translation assistance in Spanish was available in all public meetings. The public survey asked community representatives and members of the public to rate each of the hazards in terms of perceived risk. Furthermore, they were asked to rate “mitigation importance” for each of the identified hazards in the Plan. The information gathered from this survey was used to inform the hazard risk prioritization process, and to ensure the Plan adequately addressed the public’s concerns and priorities. The survey was available in English, Spanish, Tagalog, Traditional Chinese, and Simplified Chinese. A total of 16 respondents that lived in the City and three (3) that worked in the City participated in the survey. Please refer to Volume 1 (Planning Area -wide Elements) for further information and supporting documentation of the public meetings and public survey.

How Public Input was Incorporated into the Plan
Information and feedback gained through the public survey, public meetings, and public comment period provided valuable data to validate and confirm the risk assessment findings and potential mitigation strategies. Specifically, feedback from the public offered during the public meetings offered greater insights into the public’s concerns regarding specific hazards and their impacts. The public also offered specific initiatives they felt would create greater resiliency for the City and its residents.

Survey results helped validate the hazards included in the Plan, the hazard ranking process, and areas where the County and jurisdictions could further improve outreach and education efforts. Open -ended responses, specifically regarding their experience wi th damages from past hazards, helped to validate hazard-specific impact data in Chapter 4 (Hazard Identification and Risk Assessment) of Volume 1 (Planning Area-wide Elements). These, and related findings, helped the County and City Core Planning Teams determine meaningful mitigation projects.

Contra Costa County, California

City of San Pablo Annex 59
After the public comment period ended, o ne (1) public feedback form was received for the City of San Pablo Annex. The Local Planning Team reviewed the comment and will implement mitigation and preparedness efforts moving forward, if deemed appropriate. However, in order to keep the Plan current after it is approved, the City will ensure that the public continues to be involved in the Plan and how it is carried out. Refer to Section B.2 of this Annex for further details on continued public engagement.

B.1. Public Comment Period
Once the draft Plan was completed, the public was given an opportunity to review and provide comments on the County Hazard Mitigation Plan, including the City of San Pablo’s Annex, prior to submitting the Plan to the State and FEMA. The countywide public comment period began on April 22, 2024, and went on through May 31, 2024. Prior to the public comment period, the Contra Costa County Core Planning Team conducted a strategy meeting with all plan participants (i.e., City of San Pablo) that served as a brainstorming session and helped determine the public outreach goals and proper outreach methods for the public comment period. Subsequently, the City of San Pablo Core Planning Team developed a public outreach strategy that meets the City’s unique needs of the community to engage stakeholders and the public during the public comment period. The City ensured equitable outreach by targeting Contra Costa County’s vulnerable communities, including the younger (under 18 years old) and elderly (over 65 years old) population, individuals with limited English proficiency, those with access and functional needs, and race and ethnic minorities (e.g., Hispanic or Latino).

The City of San Pablo Local Planning Team coordinated with its stakeholders to ensure that the public had an opportunity to learn about the Plan, mitigation actions planned for their community, and ways to get involved in the planning process. Outreach to the San Pablo community involved a combination of in person, printed, and digital media starting on April 22, 2024, through the end of the public comment period on May 31, 2024. To ensure equitable outreach a calendar was created to strategize and map all events.

Printed Materials
Two (2) different types of materials were created specifically for the public comment period. The trifold (Figure B-1) contains information on the planning process, the top three (3) hazards in the County, ways to prepare, and ways to get involved in the planning process. A full-page flyer (Figure B-2) was created with information on the planning process, ways to get involved, and ways to prepare. Printed materials were distributed in English and Spanish outreach events. Having the materials available in multiple languages allowed more of the community to receive information about the Hazard Mitigation Plan, ways to comment, and how to prepare for disasters. Printed materials are especially helpful to communities with limited English proficiency as the materials include a visual component.

Stakeholder Engagement
Due to the size of the Plan (the Base Plan and 40 annexes), some stakeholders would receive the same invitation a significant amount of times. For a more productive outreach and to avoid overwhelming stakeholders, Contra Costa County sent a single invitation to all the countywide stakeholders via e-mail.

However, each plan participant was required to cross -reference the countywide list and identify the stakeholders that applied specifically to their jurisdiction. Not only did this help ensure that a comprehensive list was compiled as part of the stakeholder engagement, but it assisted each plan participant identify any additional stakeholders that may have not been on the list. Table 25 outlines the stakeholders the City of San Pablo identified and provided an opportunity to review and provide feedback on the draft Plan and Annex, via the countywide stakeholders e-mail.

APPENDIX C. HAZARD RISK ASSESSMENT METHODOLOGY
As part of the Contra Costa County Office of Emergency Services (OES), the risk assessment identifies the natural, human-caused, and technological hazards that have potential impacts on all or portions of the County. Hazard identification, historical occurrences, and risk modeling (where applicable and available for specific hazards) information was collected from multiple sources including, but not limited to:

• Environmental Systems Research Institute (Esri)
• Federal Emergency Management Agency (FEMA)
• National Centers for Environmental Information (NCEI) • National Weather Services (NWS)
• United States Geological Survey (USGS)
• Local repositories
This information was analyzed to assess the risk and vulnerability of people, property, the environment, and the jurisdiction’s essential operations from these hazards. Furthermore, a risk ranking was performed for the hazards of concern described in this Plan. The risk ranking is an important step in developing an action plan, as it allows jurisdic tions to compare the risk factors from one hazard to another. That comparison provides critical information to use in selecting hazard mitigation actions and their priorities.

This process is not only intended to help focus actions on the hazards with the highest ranking, but also to ensure that jurisdictions are aware of the hazards that ranked low yet still pose significant risk.

In order to provide an informed and comprehensive ranking of the hazards addressed in this Plan, a number of factors were considered: probability, extent, vulnerability, and impact. The sum of all the weighted factors for the extent, vulnerability, and impact categories was combined into a final consequence score. Probability multiplied by consequence resulted in a total risk score for each hazard.

These results were determined by following a data driven quantitative assessment, reviewing, and ranking local knowledge from local subject matter experts, and developing other risk elements by the Core Planning Team based on the data collected. These elem ents were then aggregated to inform the analysis.

At the fundamental level, consequence is an assessment of the potential impact(s) if the hazard incident actually occurs. In this assessment, the consequence of an event (or the impact) will be interdependent on the following factors:

• Vulnerabilities (i.e., social, physical, and community conditions) • Capabilities and capacities
• Mitigation
Extent + Vulnerability + Impact = Consequence

Consequence x Probability = Total Risk Score
2024 Hazard Mitigation Plan
Contra Costa County, California

City of San Pablo Annex 74
• Characteristics of the hazard event (i.e., magnitude, scale) The frequency/probability of the hazard is not included in assessing the consequence because without the event, there is no consequence or impact.

C.1. Probability of Occurrence
The probability of occurrence of a hazard is indicated by a probability factor based on the likelihood of annual occurrence. Numerical probability factors were assigned as follows.

Table 26 outlines the probability of occurrence factors used in the risk assessment calculations for this Plan. A significant hazard event is defined as any hazard occurrence that directly or indirectly damages structures or infrastructure, impedes normal business operations, and/or is likely to cause serious or fatal injuries.

Table 26. Probability of Occurrence
Probability Description Probability
Factor
High Significant hazard event is likely to occur annually. 3 Medium Significant hazard event is likely to occur within 25 years. 2 Low Significant hazard event is likely to occur within 100 years. 1 Unlikely There is little to no probability of significant occurrence, or the recurrence interval is greater than every 100 years. 0

The assessment of hazard frequency is generally based on past hazard events in the area and professional judgment of local subject matter experts.

C.2. Extent Factors
Extent was assessed in two (2) categories – extent/intensity potential and catastrophic probability of the hazard. Numerical extent factors were assigned as follows.

C.2.1. Extent/Intensity Factor
Extent is defined as the range of anticipated intensities of the identified hazards. This category is most commonly expressed using various scientific scales (e.g., Saffir -Simpson, Enhanced Fujita, Modified Mercalli). Extent/Intensity Factors are hazard-specific and are detailed in each hazard profile. Table 27 outlines the extent/intensity factors used in the risk assessment calculations for this Plan.

Table 27. Extent/Intensity Factor
Probability Description Extent
Factor
High Historical and/or probabilistic models/studies for this hazard indicate the possibility of a high-intensity incident. 3
Medium Historical and/or probabilistic models/studies for this hazard indicate the possibility of a medium-intensity incident. 2
Low Historical and/or probabilistic models/studies for this hazard indicate the possibility of a low-intensity incident. 1
Unlikely Historical and/or probabilistic models/studies for this hazard indicate the possibility of little to no intensity. 0

City of San Pablo Annex 75
C.2.2. Catastrophic Factor
The probability that a hazard could be catastrophic. Catastrophes are defined as significant incidents that cause sudden and great harm or destruction. Table 28 outlines the catastrophic factors used in the risk assessment calculations for this Plan.

Table 28. Catastrophic Factor
Probability Description Extent
Factor
High Catastrophic hazard event is likely to occur at least once in 10 years. 3 Medium Catastrophic hazard event is likely to occur at least once between 11 and 50 years. 2
Low Catastrophic hazard event is likely to occur at least once in 51 or more years. 1
No Impact Virtually no probability that this hazard could be catastrophic. 0

Each category was assigned a weighting factor to reflect its significance, consistent with this typically used for measuring the benefits of hazard mitigation actions – a weighting factor of three (3) was assigned for Extent/Intensity and its potential for Catastrophe.

C.3. Vulnerability Factors
Vulnerabilities were assessed in three (3) categories – population exposure, property exposure, and exposure based on changes in development. Numerical vulnerability factors were assigned as follows.

C.3.1. Population Exposure Factor
Population exposure values were assigned based on the percentage of the total population exposed to the hazard event. Table 29 outlines the population exposure factors used in the risk assessment calculations for this Plan.

Table 29. Population Exposure Factor
Probability Description Vulnerability
Factor
High 30% or more of the population is exposed to the hazard. 3 Medium 15% to 29% of the population is exposed to the hazard. 2 Low 14% or less of the population is exposed to the hazard. 1 No Vulnerability None of the population is exposed to the hazard. 0 C.3.2. Property Exposure Factor
Property exposure values were assigned based on the percentage of the total property value exposed to the hazard event. Table 30 outlines the property exposure factors used in the risk assessment calculations for this Plan.

Low 9% or less of the total assessed property value is exposed to a hazard. 1
No Vulnerability None of the total assessed property value is exposed to a hazard. 0 C.3.3. Changes in Development
Changes in development in the past five (5) years have increased or decreased the community’s vulnerability/exposure to the hazard. Table 31 outlines the changes in development factors used in the risk assessment calculations for this Plan.

Table 31. Changes in Development Factor
Probability Description Vulnerability
Factor
High Changes in development have increased the vulnerability/exposure of the community to the hazard by 10% or more. 3
Medium Changes in development have increased the vulnerability/exposure of the community to the hazard between 5% and 9%. 2
Low Changes in development have increased the vulnerability/exposure of the community to the hazard by 4% or less. 1
No Vulnerability Changes in development had no effect and/or have decreased the vulnerability/exposure of the community to the hazard. 0

Each category was assigned a weighting factor to reflect the significance, consistent with those typically used for measuring the benefits of hazard mitigation actions – a weighting factor of three (3) was assigned for Population Exposure, and a weighting factor of one (1) was assigned for Property Exposed and Changes in Development.

C.4. Impact Factors
Hazard impacts were assessed in eight (8) categories – population and life/safety, underserved/equity, property damages, economic, environmental, essential operations, future development, and climate change. Numerical impact factors were assigned as follows.

C.4.1. Population and Life Safety Factor
Population and life safety values were assigned based on the best available data (historical and probabilistic) for people vulnerable to the hazard event and whether the affected population is likely to experience adverse impacts from the hazard incident. Table 32 outlines the population and life safety factors used in the risk assessment calculations for this Plan.

No Impact Populations exposed to this hazard are not likely to experience significant adverse impacts. 0
C.4.2. Underserved/Equity Factor
Underserved/equity values were assigned based on the best available data for underserved populations vulnerable to the hazard event and whether the affected population is likely to experience adverse/disproportionate impacts from the hazard incident resulting in greater disparity in equity. Table 33 outlines the underserved/equity factors used in the risk assessment calculations for this Plan.

Table 33. Underserved/Equity Factor
