APPENDIX A. HAZARD MAPS
The following hazards were mapped for the City of Pinole – earthquakes, floods, landslides, sea level rise, tsunamis, and wildfires.
• Figure 1 illustrates the liquefaction susceptibility, which helps assess potential damage from earthquakes in the City.
• Figure 2 illustrates the City of Pinole 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 sea level rise projections of one (1) foot within the City. • Figure 5 illustrates the California Tsunami Hazard Areas which represent areas within the City of Pinole that could be exposed to tsunami hazards during a tsunami event. Areas in yellow are advised to evacuate immediately after an earthquake that lasts for an extended period of time or if an official evacuation notification is received. Residents and visitors are advised to evacuate on foot to a green area.
• Figure 6 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 priorities 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 Pinole 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 Pinole 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 31 respondents that lived in the City and 10 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 with 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.
2024 Hazard Mitigation Plan
Contra Costa County, California
City of Pinole Annex 60
After the public comment period ended, five (5) public feedback forms were received for the City of Pinole Annex. The Local Planning Team reviewed the comments 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 Pinole’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 Pinole) 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 Pinole 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, and those with access and functional needs.
The City of Pinole 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 City of Pinole community involved a combination of in person, printed, and digital media starting on April 20, 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 at public meetings and 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 24 outlines the stakeholders the City of Pinole 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 jurisdictions 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 elements 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 Pinole Annex 77
• 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 25 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 25. 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 26 outlines the extent/intensity factors used in the risk assessment calculations for this Plan.
Table 26. 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
2024 Hazard Mitigation Plan
Contra Costa County, California
City of Pinole Annex 78
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 27 outlines the catastrophic factors used in the risk assessment calculations for this Plan.
Table 27. 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 28 outlines the population exposure factors used in the risk assessment calculations for this Plan.
Table 28. Population Exposure Factor
Probability Description Vulnerability

CITY COUNCIL
REPORT 10.C.
DATE: MAY 20, 2025
TO: MAYOR AND COUNCIL MEMBERS
FROM: David Hanham, Planning Manager, 510-724-9842, [email protected] SUBJECT: INTRODUCE AN ORDINANCE DESIGNATING FIRE HAZARD SEVERITY
ZONE MAPS
RECOMMENDATION
Staff recommends the City Council waive the first reading and introduce an Ordinance (Uncodified) (Attachment A) to approve the City of Pinole Fire and Resource Assessment Program (FRAP) Map to designate Fire Hazard Severity Zones and direct staff to assess local implications related to zoning, building codes, defensible space requirements, and public education.
BACKGROUND
In response to the growing risk of catastrophic wildfires, the California Department of Forestry and Fire Protection (CAL FIRE) has released updated Fire Hazard Severity Zone (FHSZ) maps for Local Responsibility Areas (LRAs), including areas within the City of Pinole (Attachment B). These updates, published on February 24, 2025, represent the first major revision since 2009 and reflect the latest wildfire behavior modeling, incorporating data on topography, vegetation, climate, and historical fire activity.
Under Government Code Section 51179 and Senate Bill 63 (Stern, 2021), local jurisdictions with fire protection responsibilities are required to adopt the updated FHSZ designations by ordinance. This adoption ensures alignment with statewide wildfire resilience strategies and provides the statutory basis for applying building code requirements, defensible space standards, and emergency preparedness measures in fire-prone areas.
As a jurisdiction that contracts with the Contra Costa County Fire Protection District (Con Fire) for fire protection services, the City of Pinole is independently responsible for adopting its own ordinance incorporating the updated maps. The County Board of Supervisors, acting as the governing body of Con Fire, must adopt the updated maps by June 24, 2025.
REVIEW AND ANALYSIS
The revised FHSZ maps categorize land within the City into one of three wildfire risk levels:
Moderate, High, or Very High. In the updated maps, all areas within Pinole are designated as Moderate. This marks a reduction from the previous 2009 map, which included areas in Pinole Valley classified as High or Very High.
The updated maps do not change zoning, property ownership, or land-use entitlements.
However, the Moderate designation may inform future planning and emergency preparedness efforts. Notably, adoption of enhanced wildfire building standards (Chapter 7A of the California Building Code) is not required in Moderate zones within Local Responsibility Areas (LRAs), such as Pinole, unless specifically adopted by the local jurisdiction.
Similarly, defensible space requirements are not automatically triggered by a Moderate designation in LRAs, but may be adopted locally to support wildfire mitigation goals. Real estate disclosure requirements, however, do apply in all designated FHSZs, including Moderate zones.
The maps were prepared pursuant to Government Code Section 51178, which directs CAL FIRE to identify and classify wildfire hazard areas, and Section 51178.5, which requires local agencies to make these maps available for public review and comment. In compliance with this requirement, public outreach was conducted by the Contra Costa County Fire Protection District (Con Fire), including a public town hall on April 1, 2025, and an online comment portal.
The District collected public input on the proposed maps, and those comments are included as a part of this report as Attachment C.
While public input is encouraged and must be made available to the governing body, comments cannot be used to alter, reduce, or remove fire hazard zone boundaries as established by the State. Local agencies may include additional areas not identified by CAL FIRE, but may not exclude any designated areas. Con Fire has opted not to expand the designated zones.
Government Code Section 51179 requires local agencies to adopt, by ordinance, the designated Moderate, High, and Very High FHSZs within 120 days of the State Fire Marshal's release of the maps. Adoption of the ordinance ensures legal compliance and alignment with the State’s wildfire planning framework. In Pinole’s case, as a city contracting with Con Fire for fire protection services, the City must independently adopt the ordinance approving CAL FIRE’s designated map.
To comply with state law and maintain consistency with regional wildfire mitigation efforts, adoption of the updated maps by ordinance is necessary. Failure to adopt the maps could result in non-compliance with state mandates and hinder local implementation of wildfire resilience programs.
FISCAL IMPACT
There is no direct fiscal impact associated with adopting the Ordinance.Failure to adopt the maps could result in non-compliance with state mandates and hinder local implementation of wildfire resilience programs.

ORDINANCE OF THE CITY COUNCIL OF THE CITY OF PINOLE
TO DESIGNATE FIRE HAZARD SEVERITY ZONES FOR THE CITY OF PINOLE
LOCAL RESPONSIBLE AREA (LRA)
WHEREAS, the California Department of Forestry and Fire Protection (CAL FIRE), through the Office of the State Fire Marshal, is authorized to identify areas of significant wildfire risk and classify lands within Local Responsibility Areas (LRAs) into Fire Hazard Severity Zones (FHSZs) pursuant to Government Code Section 51178; and WHEREAS, Government Code Section 51179 requires local agencies with fire protection responsibility to adopt CAL FIRE’s recommended LRA Fire Hazard Severity Zone maps by ordinance following public review; and
WHEREAS, on February 24, 2025, CAL FIRE released updated FHSZ maps for LRAs statewide, incorporating the latest scientific models related to topography, fire weather, fuel loads, and historical wildfire data; and
WHEREAS, the updated maps assign the entirety of the City of Pinole to the "Moderate" Fire Hazard Severity Zone designation, replacing prior maps that included areas identified as "High" and "Very High"; and
WHEREAS, adoption of these updated designations enables continued alignment with state wildfire mitigation efforts and supports implementation of risk reduction strategies such as defensible space and resilient development practices.
NOW THEREFORE, BE IT RESOLVED, pursuant to the findings stated herein, that the City Council of the City of Pinole does ordain as follows:
Section 1. Recitals. The above recitals are true and correct and made a part of this Ordinance.
Section 2. Summary. This ordinance is adopted to designate updated Fire Hazard Severity Zones within the jurisdictional boundaries of the City of Pinole, pursuant to Government Code Section 51179.
Section 3. Designation of Fire Hazard Severity Zones. The City of Pinole hereby designates the Fire Hazard Severity Zones shown on the map attached hereto as Exhibit A, as identified and recommended by the California Department of Forestry and Fire Protection, Office of the State Fire Marshal, pursuant to Government Code Section 51178. The map is hereby approved and incorporated by reference into this
ordinance. An electronic version of the adopted map shall be maintained and made publicly accessible via the City of Pinole’s official website.
Section 4. CEQA Determination. The City Council finds that this action is exempt from the requirements of the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15061(b)(3), the “Common Sense” exemption, because it can be seen with certainty that there is no possibility the adoption of the Fire Hazard Severity Zone map will have a significant effect on the environment.
Section 5. Severability. If any section, subsection, sentence, clause or phrase of this ordinance is for any reason held to be invalid or unconstitutional by a decision of any court of competent jurisdiction, such decision will not affect the validity of the remaining portions of this ordinance. The City Council hereby declares that it would have passed this ordinance and each of every section, subsection, sentence, clause, or phrase not declared invalid or unconstitutional without regard to whether any portion of the ordinance would be subsequently declared invalid or unconstitutional.
Section 6. Effective Date and Duration. This ordinance shall take effect thirty (30) days after its final adoption.
Section 7. Publication. The City Clerk is directed to cause this ordinance to be published in a manner required by law.
