Ryan Kodama, Accounting Manager
Agenda Item Title
Accept the Expenditure Report for the Month of August 2026 Summary
The attached report shows disbursements by fund for the month of August 2026.

During the month, the City paid its annual premiums for FY2026-27 property, liability and workers compensation insurance totaling $899,546. Since this cost was paid in full at one time rather than spread out over the fiscal year, the budgeted expenditures coupled with the similar one-time payments for CalPERS UAL last month, have skewed the current percentages of budget for most departments in Fund 100 (General Fund) as well as Funds 501 (Cemeteries) and 510 (Water Utility) higher than if the costs were spread over 12 months.

A detailed list of disbursements is available at the web site indicated at the bottom of the report.

Public Education & Government (Fund 202): Special revenue fund accumulates fees from telecommunication operators to support public, educational and government telecommunications, including broadcasting public meetings. Costs associated with acquiring equipment, renovating and constructing PEG-related facilities and broadcasting are paid from this fund.

Strong Motion (Fund 203): Accounts for State of California "strong motion" fees paid by building permit applicants. Funds are paid regularly to State Department of Conservation.

Asset Forfeiture (Fund 211): Accounts for funds received from seizure and forfeiture of assets that represent the proceeds of, or were used to facilitate, crime. Funds are expended according to legal restrictions.

City of Sonoma
Gas Tax (Fund 302): The State of California imposes per-gallon excise taxes and sales taxes on gasoline and diesel fuel, and registration taxes on motor vehicles with allocations dedicated to transportation purposes. Gas taxes can be used for any street or road purpose; however, it is best practice to focus on maintenance and rehabilitation costs only.

SB-1 Road Maintenance (Fund 303): The Road Repair and Accountability Act of 2017 (SB1) increased pergallon excise taxes and sales taxes on gasoline and diesel fuel, and vehicle registration taxes, stabilized price-based fuel tax rates and provided for inflationary adjustments to rates in future years.

Parks & Facilities (Fund 304): This Capital Improvement Fund represents a transfer of funds from the General Fund to support improvements to the City's 17 parks encompassing nearly 40 acres, nine play structures, two public restrooms, Class I bike trails, hiking trails, a duck pond, and a rose garden. Park needs that exceed the capacity of City and contract workers are included in this fund.

Fire Measure H (Fund 312): Sonoma County measure uses a ½ cent countywide sales tax to improve fire services.

Transportation Measure M (Fund 313): The Traffic Relief Act for Sonoma County (Measure M) provides for a ¼ cent sales tax that is apportioned to local jurisdictions to maintain their streets, as well as other County-wide street, highway, transit, and safe bicycle and pedestrian routes.

Parks-In-Lieu/Quimby Act (Fund 314): The 1975 Quimby Act (California Government Code §66477) authorized the City to pass ordinances requiring developers set aside land, donate conservation easements, or pay fees, which can only be used for new and rehabilitating existing parks and recreational facilities and cannot be used for the operation and maintenance of park facilities. The City currently has a parkland dedication (exaction) requirement as a condition of approval for Tentative Subdivision Maps or Tentative Parcel Maps.

Parks Measure M (Fund 315): Sonoma County Parks Improvement, Water Quality and Fire Safety Measure (Measure M) is a one-eighth cent sales tax that supports Sonoma County’s regional and city parks Prop 68 Parks (Fund 316): Known as the California Clean Water and Safe Parks Act, Proposition 68 allocates funds to construct and rehabilitate parks, implement water improvements for safe drinking water, increase recycling and flood protection, and encourage climate change adaptation projects.

Successor Agency (Fund 391): The City of Sonoma has elected to serve as the Successor Agency to the Sonoma Redevelopment Agency, which was dissolved by the State through the Redevelopment Dissolution Act in 2012. The City as Successor Agency receives pass through revenue when property taxes are remitted to the City by the County via RPTTF (Redevelopment Property Tax Trust Fund). The City then makes authorized payments from Successor Agency for expenses, such as debt service costs, contract services for contracts issued before the dissolution of the development agency, and other expenses, including legal services.

Agenda Item Title
Adopt a Resolution Amending the City of Sonoma Conflict of Interest Code Summary
The Political Reform Act of 1974 requires local government agencies to review their Conflict of Interest Codes biennially. A local agency’s conflict of interest code must reflect the current structure of the organization and properly identify officials and employees who should be filing Statements of Economic Interests (Form 700s). A code tells public officials, governmental employees, and consultants what financial interests they must disclose on their Form 700s. It helps provide transparency in local government as required under the Political Reform Act.

Effective January 1, 2026, state law expanded the existing requirement for two hours of ethics training every two years to include department heads and other administrative or managerial employees serving in similar positions within local government agencies.

Also, effective January 1, 2026, state law established an additional requirement for two hours of financial and fiscal responsibility training every two years. This requirement applies to elected officials, appointed officials, and designated employees whose responsibilities include making decisions about public funds or providing recommendations concerning public finances.

The City Council approved the most recent Conflict of Interest Code in November 2025.

However, due to these recent legislation changes and a few staffing changes, additional amendments are required. These amendments are as follows:

1. The Assistant City Manager/Administrative Services Director position has been changed to Administrative Services Director.

2. The Finance Director position was removed as it is now considered a Government Code 87200 filer and is included with those positions in the footnotes.

3. Other positions were removed as they are no longer on the City Salary Scale.

4. The positions required to complete the Ethics and Fiscal & Financial Responsibility training are designated in Exhibits C and D for clarity.

The Conflict of Interest Code has been updated to reflect all of the above changes (Exhibit “A”).

Recommended Council Action
Adopt the resolution.

Adopt a Resolution Approving the Use of City Streets for the Sonoma Valley High School Homecoming Parade on October 9, 2026, and Permission to Up-Light City Hall from October 5, 2026, through October 11, 2026, with Green Flood Lights Summary
City Council approval is required for special event permits that include street closures.

Sonoma Valley High School has submitted an application for its annual Homecoming Parade, scheduled for Friday, October 9, 2026, from 1:00 p.m. to 1:30 p.m. The parade route will begin at Sonoma Valley High School, proceed north along Broadway (State Route 12), and conclude in the horseshoe of the Plaza. Because the route includes use of State Route 12, Caltrans approval and an encroachment permit may also be required.

This is a recurring event in the Plaza. In prior years, the City Council has approved the requested street closures, and the event has taken place without incident or controversy.

The application includes intermittent street closures along the parade route, which have been coordinated with City staff, Police, and Fire. The event is considered a community tradition that engages students, families, and the public in a safe and celebratory manner. For the past several years, the City of Sonoma has also shown support by illuminating City Hall in green for the days leading up to Sonoma Valley High School's Homecoming weekend.

The event and street use fee waivers were previously authorized under the Community Recreation and Community Service Program, which City Council adopted by Resolution #31- 2022 on June 1, 2022.

Recommended Council Action
Staff recommends that the City Council adopt a resolution approving the requested use of City streets for the Sonoma Valley High School Homecoming Parade and light installation on City Hall, subject to the following conditions:

1. Sonoma Valley High School must obtain an encroachment permit from Caltrans (State of California Division of Highways).

2. Sonoma Valley High School must submit to the City a valid insurance certificate in compliance with the City of Sonoma Facility Use Insurance Requirements prior to the event.

3. Sonoma Valley High School representatives must meet with the Police Chief, Parks Supervisor, and Streets Supervisor at least two weeks prior to the event to finalize traffic control plans and submit a written request for special barricading.

4. Sonoma Valley High School must provide adequate supervision to ensure the Plaza is returned to pre-event condition and that all Plaza Use conditions and restrictions are adhered to.

City of Sonoma
Agenda Item Summary
Meeting: City Council - 16 Sep 2026
Department
Administration
Staff Contact
Michael Berger, Public Works Director
Agenda Item Title
Adopt a Resolution of the City Council of the City of Sonoma Adopting Volume 1, Volume 2 - Section 10 (The City Of Sonoma Annex), and the Appendices of Volume 2, of the Sonoma County Multijurisdictional Hazard Mitigation Plan
Summary
Summary
The 2026 Sonoma County Multi-Jurisdictional Hazard Mitigation Plan (HMP) is a comprehensive, countywide effort to identify natural hazards, assess community vulnerabilities, and establish strategies to reduce or eliminate long-term risks to people, property, infrastructure, the environment, and the economy. The plan updates the 2021 HMP and was developed under the leadership of the Sonoma County Department of Emergency Management in partnership with 22 participating jurisdictions and special districts, including the City of Sonoma.

For the City, the value of the HMP process extends beyond maintaining eligibility for certain federal mitigation funding. The update provided a structured opportunity for staff across departments and disciplines to identify local vulnerabilities, evaluate the City's existing capabilities, review progress since the previous plan, and establish mitigation priorities that can help inform City planning and operations over the next five years.

Development of the City's annex was an interdepartmental effort involving staff with operational and subject-matter expertise from across the organization, together with Sonoma Valley Fire District and other partners. Staff reviewed existing vulnerabilities and capabilities, evaluated previous mitigation actions, and identified actions for the next five years with an emphasis on developing a mitigation strategy grounded in identified local vulnerabilities, existing City responsibilities, and opportunities to integrate mitigation into ongoing and future City work.

Some of the work identified in the updated HMP is already underway or builds upon existing City initiatives, demonstrating that the plan is intended to serve as a working framework for ongoing resilience efforts rather than simply a list of future projects.

Background
Hazard mitigation is the use of long- and short-term policies, programs, projects, and other activities to reduce the loss of life, injury, property damage, and other impacts that can result from disasters. Maintaining a current FEMA-approved Hazard Mitigation Plan also establishes eligibility for certain federal hazard mitigation grant programs.

Agenda Item #7.6:

Page 62 of 231 ends

Sonoma County Department of Emergency Management served as the lead agency for the 2026 multi-jurisdictional update, coordinating the participating jurisdictions and special districts, managing the consultant team, facilitating the regional planning process, and coordinating review by the California Governor's Office of Emergency Services (Cal OES) and Federal Emergency Management Agency (FEMA). The City appreciates the County's leadership and the significant technical and administrative resources it provided throughout this multi-year effort.

The regional nature of the HMP is particularly important for Sonoma. The City encompasses approximately 2.72 square miles within the larger Sonoma Valley, and many of the hazards facing the community do not stop at jurisdictional boundaries.

Fire protection, transportation, water supply, utilities, emergency response, and community services connect the City with surrounding unincorporated areas. Regional mitigation efforts therefore directly support the City's resilience, just as mitigation undertaken within the City can benefit the broader Sonoma Valley.

The HMP consists of a countywide plan in Volume I and jurisdiction-specific annexes in Volume II. Section 10 of Volume II is the City of Sonoma Annex. It describes Sonoma's community characteristics, local capabilities, hazard vulnerabilities, status of previous mitigation actions, and mitigation strategy for the next five-year planning period. The annex is intended to function as a living document and implementation tool.

City of Sonoma Planning Process
Development of the City annex was a collaborative, interdepartmental process involving Public Works, Administration, Community Development, Sonoma Valley Fire District, the City's emergency planning consultant, and staff with relevant technical and operational expertise. Staff from across the organization contributed their knowledge of City facilities, infrastructure, programs, operations, and community needs to help identify vulnerabilities and develop potential mitigation actions.

This broad participation was important to developing a mitigation strategy grounded in the City's actual responsibilities, capabilities, and ongoing work. Staff sought to identify actions that could realistically inform or be integrated into City programs, projects, plans, and operations over the five-year life of the HMP.

Staff reviewed the status of mitigation actions contained in the 2021 HMP and considered whether those actions had been completed, should continue, or should be modified. Actions that remain relevant but are incomplete or in progress were considered alongside newly identified actions.

What's New in the 2026 HMP
The 2026 HMP evaluates 11 hazards of concern: dam failure, drought, earthquake, extreme cold, extreme heat, extreme wind, flooding, landslide, sea level rise, tsunami, and wildfire.

The former severe weather category has been refined, with extreme wind evaluated Agenda Item #7.6:

Page 63 of 231 ends

as an individual hazard and extreme heat and extreme cold added as separate hazards of concern. For Sonoma, these changes reflect increasing attention to the impacts of temperature and weather extremes on vulnerable populations, infrastructure, emergency operations, and community services.

Climate change is also addressed differently in the updated plan. Rather than treating climate change as a separate hazard, the HMP considers how changing climate conditions may affect the frequency, severity, or consequences of individual hazards.

This allows climate impacts to be considered in the context of wildfire, drought, extreme heat, flooding, extreme weather, and other hazards where those effects occur.

The update also places greater emphasis on connecting hazard mitigation to existing plans, programs, regulations, capital projects, and City operations.

City Mitigation Strategy and Implementation
The City's updated mitigation strategy includes 33 potential mitigation actions spanning emergency preparedness, wildfire risk reduction, infrastructure resilience, water and energy reliability, community preparedness, and other areas. These potential mitigation actions are summarized in table 10-27, with the respective actions spelled out in the following pages of the report (pg. 10-53). These mitigation actions include both ongoing City activities and potential initiatives.

The City's mitigation actions were developed with an emphasis on identified needs, practical implementation, and alignment with existing City responsibilities and priorities. Some actions can be advanced through existing programs and work plans, while others may require future budget allocations, outside funding, regional partnerships, or additional staff capacity. Inclusion in the HMP does not guarantee that funding will be available or that an action will be implemented within the five-year planning period.

Maintaining an approved HMP does, however, preserve the City's eligibility to pursue certain hazard mitigation funding opportunities when they are available. Individual projects will continue to be evaluated based on need, feasibility, available resources, and applicable City approval processes.

Implementation of some mitigation activities is already underway. For example, the HMP identifies development of hazard-specific Emergency Operations Plan annexes for extreme heat, extreme cold, and extreme wind as a mitigation action. The City has already begun this work through development of an Extreme Cold Annex. Other mitigation activities documented in the HMP include ongoing wildfire vegetation management and defensible-space work and recently completed efforts such as the citywide tree inventory and canopy study.

The updated HMP also documents progress from the previous planning cycle. For example, replacement of the Chase Street Bridge was identified as a mitigation action in the previous HMP and is now listed as completed following replacement of the bridge in 2022, including increased hydraulic capacity to better accommodate storm events.

Agenda Item #7.6:

Page 64 of 231 ends

The resulting mitigation strategy is intended to inform existing City functions, including capital improvement planning, emergency preparedness, infrastructure maintenance, land-use and development planning, water system management, wildfire prevention, and public education and outreach.

Inclusion of an action in the HMP does not itself appropriate funding or constitute approval of an individual project. Future projects will remain subject to available resources and applicable City budgeting, procurement, environmental review, and approval requirements.

Public and Stakeholder Engagement
The County conducted broad regional public engagement during development of the HMP, including a bilingual hazard mitigation survey, public meetings, stakeholder outreach, and a formal public review period. The City supplemented the County's regional outreach through its own communications, including website and social media outreach, a dedicated HMP webpage, community partner engagement, and promotion of the public review process.

On November 6, 2025, the City, Sonoma County Department of Emergency Management, and Sonoma Valley Fire District co-hosted a Sonoma Valley-focused public meeting at Sonoma Valley Fire District Station No. 1 to provide information about the draft HMP, discuss the City of Sonoma annex, and provide an opportunity for community input. Spanish interpretation was available.

The City's planning process also considered community input received through related efforts occurring concurrently with the HMP update, including the General Plan and Safety Element update, Fire Hazard Severity Zone process, and evacuation planning.

Plan Adoption and FEMA Eligibility
Cal OES and FEMA have reviewed the HMP and determined it to be approvable pending adoption. Each participating jurisdiction must formally adopt the plan for its jurisdiction to receive final FEMA approval and maintain eligibility for applicable FEMA hazard mitigation funding.

Upon City Council adoption, the executed resolution will be transmitted as required to complete the approval process.

Recommended Council Action
Adopt the enclosed resolution adopting Volume 1, Volume 2 - Section 10 (The City of Sonoma Annex), and the Appendices of Volume 2 of the Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2026.

Alternative Actions
Agenda Item #7.6:

Page 65 of 231 ends

Financial Impact
There is no direct fiscal impact associated with adoption of the HMP. Adoption does not commit the City to funding or implementing individual mitigation actions.

Maintaining a current FEMA-approved HMP preserves the City's eligibility to apply for certain federal hazard mitigation funding. Potential future mitigation projects would be considered through the City's normal budget, capital improvement, grant, and project approval processes.

10. CITY OF SONOMA
This jurisdictional annex to the Sonoma County Hazard Mitigation Plan (HMP) provides information to assist public and private sectors in the City of Sonoma with reducing losses from future hazard events.

This annex is not guidance for what to do when a disaster occurs; the focus is actions that can be implemented prior to a disaster to reduce or eliminate damage to the people, property, environment, or economy of the City. The annex presents a general overview of Sonoma, describes who participated in the planning process, assesses local risk, vulnerability, and capabilities, and outlines a strategy for achieving a more resilient community.

10.1 HAZARD MITIGATION PLANNING TEAM
The City of Sonoma identified primary and alternate HMP points of contact and developed this plan over the course of several months, with input from many City departments. The Department of Public Works represented the community on the Sonoma County HMP Planning Partnership and Hazard Mitigation Working Group and supported the local planning process by securing input from persons with specific knowledge to enhance the plan. All departments were asked to contribute to the annex development through reviewing and contributing to the capability assessment, reporting on the status of previously identified actions, and participating in action identification and prioritization.

The City officials who participated in the development of the annex are listed below and shown in
Table 10-1. Additional documentation of the City’s planning activities through Planning Partnership meetings is included in Volume I.

10.2 COMMUNITY PROFILE
The City of Sonoma is a historic municipality in the heart of the Sonoma Valley wine region in Sonoma County, approximately 45 miles north of the Golden Gate Bridge. The city encompasses an area of

2.72 square miles. Its boundaries generally extend from Leveroni Road/Napa Road in the south to Verano Avenue/Brazil Street in the north, and from Sonoma Highway in the west to Sixth Street East/Knight Street in the east.

Sonoma was first incorporated on April 4, 1850, the year that California achieved statehood. The city was later unincorporated in 1862 and re-incorporated on September 3, 1883. The cornerstone of Sonoma City Hall was laid in 1906, marking a new era of civic development.

Sonoma’s cultural heritage is celebrated through several annual events. Pueblo Day, observed each June 24, commemorates the founding of the Pueblo de Sonoma in 1835. The Hispanic community celebrates Cinco de Mayo, honoring the 1862 victory at the Battle of Puebla, and the city also hosts a re-enactment each June 14 of the Bear Flag Revolt, the 1846 uprising that played a pivotal role in California’s path to statehood.

The City of Sonoma operates under a council/manager form of government. A five-member City Council, elected to overlapping four-year terms, provides policy leadership and legislative oversight.

Sonoma County Hazard Mitigation Plan
City of Sonoma 10-3
Law enforcement services are provided through a contract with the Sonoma County Sheriff’s Office.

Fire protection is provided by the Sonoma Valley Fire District. Educational services fall under the Sonoma Valley Unified School District. Sewer services are managed by the Sonoma Valley County Sanitation District, operated by Sonoma Water. The City operates its own water system, with Sonoma Water serving as the primary supplier. Health care services are provided by Sonoma Valley Hospital through the Sonoma Valley Health Care District.

According to the U.S. Census, the 2020 population for Sonoma was 10,739, a 0.85 percent increase from the 2010 Census. The 2023 American Community Survey estimated that the 2023 population of Sonoma was 10,726; this estimate is used throughout the HMP.

Some populations are at greater risk from hazard events because of decreased resources or physical abilities for responding during a hazard, and the location and construction quality of their housing. The 2023 American Community Survey indicates that 3.1 percent of the population is 5 years of age or younger, 32.6 percent is 65 years of age or older, 1.2 percent is non-English speaking, 8.3 percent is below the poverty threshold, 16.7 percent have disabilities, 2.0 percent live in a single parent household, and 0.6 percent have no vehicle access.

In 2024, the total homeless population in the City of Sonoma was reported as 13 individuals, all of them unsheltered (Sonoma County 2024).

10.3 PUBLIC ENGAGEMENT
Volume I of this HMP describes the outreach to the public that was undertaken on behalf of all participating jurisdictions to prepare this HMP update. In addition to that work, the City of Sonoma completed specific activities to collect input on hazards and vulnerability from the people the City serves. The public was invited to participate in the plan by responding to the public survey, attending a virtual Hazard Mitigation Working Group meeting, attending an in-person meeting, and reviewing the draft plan.

To ensure meaningful and inclusive participation, the City used a layered, multi-channel outreach strategy that included the following:
• Posts on the City website with multilingual translation tools and accessibility features • City newsletters and social media content tailored to different community segments • Water bill inserts reaching all utility customers, including renters • Flyers and printed materials distributed at the library, senior center, community markets, clinics, and service provider locations
• Collaboration with Community-Based Organizations (CBOs) serving unhoused individuals, agricultural workers, people over 65, non-English speakers, LGBTQ+ community members, and low-income households
• Outreach through local media, including newspapers, radio, and digital outlets Agenda Item #7.6:

Further outreach activities are documented in Appendix D (Outreach Documentation), including photos from a public meeting. Flyers provided for the campaign were printed and distributed at key community locations such as the Sonoma Valley Library, Vintage House Senior Center, Whole Foods community bulletin board, and the Sonoma Community Center, with additional placements planned as needed.

An email was sent to local community-based organizations and nonprofits with details about the public comment period and upcoming meetings. Flyers were also posted at the Sonoma Valley Community Health Center. Outreach extended to the Springs and North Valley Municipal Advisory Councils to ensure broad community engagement.

To ensure active involvement in the hazard mitigation planning process by underserved communities and vulnerable populations within the City of Sonoma and the Sonoma Valley Fire District, a multifaceted, accessible, and culturally sensitive outreach approach was implemented. This engagement strategy prioritized equity, transparency, and participation, ensuring that all voices were heard in shaping the community’s resilience efforts. The following targeted outreach was made to underserved communities and vulnerable populations:

Underserved Communities:
• Renters and low-income households who may face financial barriers to home retrofits or personal preparedness
• Agricultural workers (seasonal and year-round farmworkers) who may live or work in rural and hazard-prone areas such as wildfire interface zones
• Non-car-owning households who may face challenges in evacuating or reaching shelters during emergencies
• Single-parent households who may experience time and resource constraints in preparing for and responding to disasters
• LGBTQ+ community members, who may face barriers in accessing safe and inclusive shelter or services during emergency events
• Isolated rural residents living in areas with limited emergency services, transportation, or infrastructure support
• Residents in overcrowded or multi-family housing units who may face increased risks during pandemics, extreme heat events, or other disasters due to space constraints • Uninsured or Underinsured Individuals who may have limited access to healthcare, exacerbating their vulnerability during crises
Vulnerable Populations:
• Unhoused individuals, especially those in encampments near creeks and open spaces prone to flood and wildfire hazards
• Under-resourced households, particularly those in mobile home parks or older housing vulnerable to extreme heat or cold
• Seniors, who may have mobility limitations or require additional support during evacuations and hazard events

10.5 CHANGES IN COMMUNITY PRIORITIES
Since the 2021 plan, the City of Sonoma has experienced evolving conditions that have led to a shift in hazard mitigation priorities. The City has faced a growing frequency of extreme cold, heat, and wind events, alongside increasingly intense atmospheric river storms. These trends, coupled with regional homelessness and affordability challenges, have elevated the urgency to address vulnerabilities in both emergency response and community preparedness.

As a result, the 2026 update includes new stand-alone hazards—extreme cold, extreme heat, and extreme wind—reflecting their heightened impact on public safety and critical infrastructure. The City has also dedicated significant emergency coordination and administrative resources toward these hazards, prompting the development of new mitigation actions focused on resilience, shelter preparedness, and outreach to vulnerable populations.

While the City has expanded its focus on emerging hazards, it continues to prioritize actions to mitigate all hazards identified in the plan. Additionally, Sonoma remains committed to coordinating with neighboring jurisdictions and regional partners to support multi-jurisdictional responses to hazards, including those that may not directly impact city lands but affect nearby communities and key transportation corridors. This plan reflects a proactive, regional approach to hazard mitigation while continuing to protect the health, safety, and well-being of all Sonoma residents.

Since the previous plan, the City’s Public Works Department has adopted a more strategic approach to capital projects, emphasizing efficiency and risk reduction. Staff are conducting a comprehensive bridge inventory and assessing seismic and hydraulic vulnerabilities to ensure structural integrity.

Additionally, the City is advancing efforts to inspect and classify its storm line system, identifying weaknesses and informing future mitigation and improvement projects.

The Sonoma Valley Fire District has refined its priorities in response to escalating wildfire threats and climate-driven hazards. With fire behavior becoming more severe due to prolonged drought, increased Agenda Item #7.6:

fuel loads, and shifting climate patterns, the District has emphasized large-scale vegetation management and fuels reduction. It has also recognized the importance of infrastructure hardening to protect emergency response facilities and essential services. These efforts position the District to pursue funding opportunities and strengthen long-term hazard resilience.

10.6 JURISDICTIONAL CAPABILITY ASSESSMENT AND

INTEGRATION
The City of Sonoma performed an inventory and analysis of existing capabilities, plans, programs, and policies that enhance its ability to implement mitigation strategies. Volume I describes the components included in the capability assessment and their significance for hazard mitigation planning. The jurisdictional assessment for this annex includes analyses of the following:
• Planning and regulatory capabilities
• Development and permitting capabilities
• Administrative and technical capabilities
• Fiscal capabilities
• Education and outreach capabilities
• Classification under various community mitigation programs • Adaptive capacity to withstand hazard events
For a community to succeed in reducing long-term risk, hazard mitigation must be integrated into dayto-day local government operations. As part of the hazard mitigation analysis, planning and policy documents were reviewed and each jurisdiction was surveyed to obtain a better understanding of its progress toward plan integration. Development of an updated mitigation strategy provided an opportunity for Sonoma to identify opportunities for integrating mitigation concepts into ongoing City procedures.

10.6.1 Planning and Regulatory Capability and Integration Planning and regulatory capabilities include the plans, policies, codes, and ordinances that help prevent or reduce the impacts of hazards. The tables below outline the relevant planning documents, codes, and regulations that were reviewed and considered for updates based on new data or insights gained during the HMP update process. Additionally, the HMP Team evaluated existing plans against a comprehensive list of hazard mitigation-related capabilities. The absence of certain types of plans, policies, codes, or ordinances was not interpreted as a gap in local capabilities. For a comprehensive list of state codes relevant to hazard mitigation in California, please refer to the capability assessment in Volume I.

10.6.2 Integration
For a community to succeed in reducing long-term risk, hazard mitigation must be integrated into dayto-day local government operations. As part of the hazard mitigation analysis, planning and /policy documents were reviewed and each jurisdiction was surveyed to obtain a better understanding of their progress toward plan integration. Development of an updated mitigation strategy provided an Agenda Item #7.6:

Page 84 of 231 ends

Sonoma County Hazard Mitigation Plan
City of Sonoma 10-17
opportunity for the City of Sonoma to identify opportunities for integrating mitigation concepts into ongoing City procedures.

Table 10-2 through Table 10-4 list the local planning mechanisms currently in place for the City of Sonoma. This review revealed that the City has made significant progress in aligning its hazard mitigation goals with broader municipal functions. Key planning mechanisms, such as the General Plan, Capital Improvement Plan, and Emergency Operations Plan, already incorporate hazard-related policies and strategies. These documents address land use, infrastructure resilience, emergency response, and environmental protection, all of which are critical to reducing long-term risk.

The City of Sonoma is committed to institutionalizing hazard mitigation across all departments. Moving forward, the City will continue to incorporate HMP findings, such as risk assessments, vulnerability data, and prioritized mitigation actions, into updates of local plans and policies. This approach ensures that hazard mitigation is not treated as a standalone effort, but as a coordinated, ongoing component of governance, planning, and community development.

10.6.4 Administrative and Technical Capability
Table 10-6 summarizes the administrative bodies and programs available to support mitigation initiatives in the City. Due to the size of the City of Sonoma, the creation of a Zoning Board is not necessary. Decisions regarding zoning/development are made by the City’s robust and active Planning Commission, which meets regularly.

While there is no City committee tasked solely with mitigation planning, the City’s Emergency Management Working Group meets monthly to discuss issues related to emergency preparedness, response, and recovery, and collaborates on all of the hazard mitigation projects listed in this document. The City plans to expand on this capability by utilizing an outside consulting team to create hazard-specific annexes to address each specific medium- and high-risk hazard discussed in this HMP, each of which will be thoroughly discussed to ensure maximum effectiveness and implementability.

Table 10-9 summarizes the education and outreach resources available to Sonoma. While the City of Sonoma does not have a standalone citizen board to address hazard mitigation, the City has a robust cadre of boards and commissions—including Climate Action, Parks & Recreation, and Planning—all of whom are informed regarding the City’s emergency preparedness and response activities. The City also organizes semi-annual meetings of the Community Partners Emergency Preparedness & Response Network—a City-led group of community based organizations and community partners— to discuss various topics, including disaster planning, hazard mitigation, and emergency response, at which time the City receives important feedback to integrate into future planning strategies.

The City of Sonoma has long-standing partnerships with the Sonoma Valley Unified School District and community partners that provide youth programming and services, including the Boys & Girls Club of Sonoma Valley, Sonoma Community Center, and Sonoma Valley Health Center, all of whom the City supports in their efforts to provide emergency preparedness and response information. While the City represents an important part of the school district, many campuses serving Sonoma Valley students are located outside of city limits, making collaboration across jurisdictions especially important. Community partners help extend the reach of preparedness efforts, with programs such as youth-focused emergency preparedness classes offered by the Sonoma Community Center and the Sonoma Valley Health Center’s annual back-to-school and emergency preparedness fairs. The Sonoma Valley Fire District also maintains an ongoing relationship with local schools, including campus visits and outreach.

Collectively, these efforts help ensure that preparedness information reaches youth and families across the broader Sonoma Valley community, including underserved residents and those whose first language is not English.

10.6.8 Adaptive Capacity
Adaptive capacity is defined as “the ability of systems, institutions, humans and other organisms to adjust to potential damage, to take advantage of opportunities, or respond to consequences” (IPCC 2022). Each jurisdiction has a unique combination of capabilities to adjust to, protect from, and withstand a future hazard event, future conditions, and changing risk. Table 10-11 summarizes the adaptive capacity for each identified hazard of concern and the City’s capability to address related actions using the following classifications:
• Strong adaptive capacity means the jurisdiction does have the capability to effectively respond, plans/policies exceed minimum requirements; deployable resources all of which decreases vulnerability.
• Moderate adaptive capacity means minimum requirements are in place; moderate capabilities; mitigation measures are identified but not implemented widespread; jurisdiction can recover but needs outside resources.
• Weak adaptive capacity means the jurisdiction does not have the capability to effectively respond, which leads to an increase in vulnerability. Examples include weak, outdated, or inconsistent plans, policies, codes, or ordinances in place; no redundancies; limited to no deployable resources; limited capabilities to respond; long recovery.

10.7 NATIONAL FLOOD INSURANCE PROGRAM COMPLIANCE
This section provides specific information on the management and regulation of the regulatory floodplain, including current and future compliance with the National Flood Insurance Program (NFIP).

The floodplain administrator listed in Section 10.1 is responsible for maintaining this information.

The City has adopted the NFIP minimum floodplain management criteria via local regulation. The latest Flood Insurance Rate Map (FIRM) was adopted by the City on December 2, 2008. The Chief Building Agenda Item #7.6:

Page 90 of 231 ends

Sonoma County Hazard Mitigation Plan
City of Sonoma 10-23
Official is responsible for implementing the requirements of the NFIP by requiring permits for all development within special flood hazard areas (SFHAs) shown on the latest FIRM. The Chief Building Official reviews proposed development for compliance with applicable floodplain standards, including elevation or floodproofing, floodway restrictions, and certification requirements. Compliance is enforced through permit conditions, inspections, and documentation, with enforcement actions taken as necessary to address non-compliant development and maintain consistency with NFIP.

The City implements the substantial improvement/substantial damage provisions of its floodplain management regulations by requiring property owners, following a damaging event or proposed improvement, to submit a detailed cost estimate prepared by a licensed contractor, along with documentation of the structure’s pre-event market value, typically based on an appraisal or local taxassessed value. Cost estimates are reviewed and evaluated in accordance with FEMA P-758, which defines costs that must be included and excluded when determining substantial improvement or substantial damage. The Chief Building Official uses this documentation to determine whether the cost of repairs or improvements equals or exceeds 50 percent of the structure’s market value. If that threshold is met, the structure is classified as substantially damaged or substantially improved and must be brought into full compliance with current floodplain management standards as a condition of permit approval. The jurisdiction documents the determination and enforces compliance through its permitting authority.

While the City participates in the NFIP, it does not participate in the CRS. Table 10-12 provides a summary of NFIP compliance in Sonoma.

As noted above, one building permit was issued in SFHAs over the past five years and major development is not scheduled to occur in any known hazard areas over the next five years. The overall vulnerability has stayed the same since the previous plan was adopted.

10.9 JURISDICTIONAL RISK ASSESSMENT
The hazard profiles in Volume I provide detailed information regarding each planning partner’s vulnerability to the identified hazards, including summaries of the City’s risk assessment results and data used to determine the hazard ranking. Key local risk assessment information is presented below.

10.9.1 Hazard Area
Figure 10-4 and Figure 10-5 show the probable hazard areas within the City. These maps are based on the best available data at the time of the preparation of this plan and are adequate for planning purposes. Maps are provided only for hazards that can be identified clearly using mapping techniques and technologies and for which Sonoma has significant exposure. Figure 10-4 illustrates the FIRM for the 1 percent and 0.2 percent annual chance floodplains. The City is not located in a dam inundation hazard area, tsunami hazard area, or sea level rise hazard area. Figure 10-5 identifies the CAL FIRE wildfire severity zones, NEHRP Class D and E soils, and the USGS-defined landslide hazard areas.

About half of the City is located in a wildfire severity zone.

10.9.3 Hazard Ranking and Vulnerabilities
The hazard profiles in Volume I have detailed information regarding each planning partner’s vulnerability to the identified hazards. The following presents key risk assessment results for Sonoma.

Hazard Ranking
The participating jurisdictions have differing degrees of vulnerability to the hazards of concern, so each jurisdiction ranked its own degree of risk to each hazard. The community-specific hazard ranking is based on problems and impacts identified by the risk assessment presented in Volume I. The ranking process involves an assessment of the likelihood of occurrence for each hazard; the potential impacts of the hazard on people, property, and the economy; community capabilities to address the hazard; and changing future climate conditions.

The City of Sonoma reviewed the preliminary hazard ranking calculated as described in Volume I to assess the relative risk of the hazards of concern to the community. The revised rankings account for the changes in community priorities described in Section 10.5 of this annex and in Volume I of this HMP.

Agenda Item #7.6:

Page 99 of 231 ends

Sonoma County Hazard Mitigation Plan
City of Sonoma 10-32
Table 10-19 shows the City of Sonoma’s final hazard rankings for the identified planning area hazards of concern. Hazards ranked as “No exposure” are not considered to be hazards of local concern and are excluded from the vulnerability assessment, potential impacts assessment, and mitigation strategy.

Mitigation actions outlined below address all hazards of local concern, targeting high and medium hazards.

Table 10-19. Hazard Ranking
Hazard Rank
Dam Failure No exposure to this hazard
Drought Medium
Earthquake Medium
Extreme Cold Medium
Extreme Heat Medium
Extreme Wind Medium
Flooding Medium
Landslide Low
Sea Level Rise No exposure to this hazard
Tsunami No exposure to this hazard
Wildfire High
Note: The scale is based on the hazard rankings established in Volume I, modified as appropriate based on review by the jurisdiction.

The dam inundation for high and very high hazard dams described in Volume I does not occur within the City’s boundaries; therefore, there is no exposure to the dam failure hazard. Because the city is inland, tsunamis and sea level rise are not expected to have an impact on the people, buildings, or critical facilities in the city.

Vulnerability to Hazards of Local Concern
Based on the above jurisdiction-specific information, this section describes vulnerability of community assets to the hazards of local concern to the City of Sonoma.

Table 10-20 summarizes the percentage of the jurisdiction’s general buildings and community lifelines located in the mapped hazard areas for the hazards of local concern. Table 10-21 shows the percentage of the jurisdiction’s total population and socially vulnerable populations in each of these hazard areas. Additional details on these results are provided in the hazard profiles in Volume I. The sections below describe local vulnerability to each hazard of local concern.

Drought
As discussed in Volume I, drought is unlikely to cause physical changes to buildings, facilities, or infrastructure. However, certain community lifelines are vulnerable to collapse if water is unavailable, such as the water systems lifeline. Six city water tanks are identified as critical facilities vulnerable to drought.

The region and state have a history of prolonged dry, hot weather and have experienced extended periods of drought, which can have severe physical and economic impacts.

Populations most vulnerable to drought are those living in high fire-risk areas and those dependent on agricultural activities that dominate local land use. Extreme drought conditions could result in water shortages that could disproportionately impact unhoused individuals and others without access to clean drinking water. It could raise the cost of water usage, and economically disadvantaged communities may be unable to afford the increased cost for potable water.

The City of Sonoma is proactively planning for the potential of cascading impacts, including increased wildfire risk. To better prepare and respond to future drought events, the City is drafting a Drought Annex to the recently updated City of Sonoma Emergency Operations Plan, which outlines potential long-term impacts on the community and strategies for mitigating drought risk, including providing information on the importance of water conservation to residents and businesses.

Earthquake
As noted in Volume I, buildings on National Earthquake Hazards Reduction Program (NEHRP) Class D and E soils are more likely to be damaged during an earthquake. Almost one-fifth of the buildings in the City (19.9 percent) are on NEHRP Class D and E soils. In addition, 19 community lifeline facilities are on Class D and E soils. This includes daycares, food distribution sites, local bridges, the Sonoma Police Department, schools, shelters, skilled nursing facilities, and solar power facilities. The population living on Class D and E soils make up 20.3 percent of the city’s total population and includes 710 people over the age of 65.

While the risk of an earthquake within the city limits is relatively small, the City of Sonoma recognizes the potential strain on resources should such an event occur nearby, as during the 1989 Loma Prieta Earthquake and the 2014 South Napa Earthquake. In large-scale regional emergencies, areas with greater population and impact, such as Santa Rosa or Napa, may receive priority for outside assistance. As a result, the City of Sonoma may experience delays in mutual aid or resource Agenda Item #7.6:

deployment and should be prepared to rely on locally available personnel, equipment, and supplies in the immediate aftermath of an event.

Additionally, regional transportation corridors used to bring in emergency resources, medical support, and essential goods may be disrupted, further limiting access to outside assistance. These conditions underscore the importance of local preparedness, including continuity of operations planning, preidentified staging areas, and coordination with community partners to support response and short-term recovery.

An earthquake in a neighboring community could result in requests for city staff to provide mutual aid, for the city to serve as an evacuation center, or other cross-jurisdictional coordination activities.

Communication with residents, especially older adults and those with access and functional needs, is critical should an event occur anywhere in the region, as there is potential for panic and overburdening of 911 and other emergency communications systems. These populations would also require additional assistance should there be a need for evacuation, sheltering in place, or other emergency response activities.

Extreme Heat
Extreme heat is unlikely to cause physical damage to buildings, facilities, or infrastructure. The city has six municipal water tanks that are in the water systems community lifeline category. During an extreme heat event, the evaporation of water inside the tanks could increase.

The City of Sonoma has had multiple extended heatwaves in recent years as a result of a changing climate. These events disproportionately impact the City’s unhoused population, older adults, underresourced individuals who may be unable to afford air conditioning, outdoor workers, the medically fragile, and those with access and functional needs.

Sonoma is a close-knit community, and many residents participate in community events. The City is cognizant of providing timely information regarding potentially hazardous conditions around events such as the annual 4th of July Parade downtown, which many older adults and people with access and functional needs participate in.

To address these risks, the City of Sonoma is drafting an Extreme Heat Event Annex to inform staff and community partners of the City’s response plans and ongoing efforts to inform the public about resources available during times of intense heat. Special attention is being given to planning for the City’s more vulnerable populations listed above. The City is strategically coordinating with communitybased organizations to optimize available staff and services.

Extreme Cold
Extreme cold is unlikely to cause physical damage to buildings and facilities, although it has the potential to freeze and burst building infrastructure that contains liquids or gases. The City of Sonoma has experienced several extreme cold events in the last five years resulting in the activation of emergency warming centers. These activations were focused on the unhoused population, who are disproportionately impacted by freezing temperatures and most at risk from hypothermia and other lifeAgenda Item #7.6:

threatening conditions related to exposure to extreme or extended cold weather. The City of Sonoma, jointly with the County of Sonoma, is updating protocols to specify the unique differences between an emergency warming center activation for public health purposes and an activation in response to a broader extreme cold weather event response. This information will be included in the Extreme Cold Weather Event Annex to be completed this year. This annex will address populations that are most at risk from adverse impacts of prolonged extreme cold weather, including older adults, outdoor workers, individuals who lack resources to afford heat, and those who are medically fragile.

Extreme Wind
The City of Sonoma has experienced severe weather events that included strong winds as a result of its location in the Sonoma valley. Falling trees or branches can cause damage to buildings and infrastructure and can result in power outages. Transportation along the Highway 12 corridor can be interrupted due to downed trees or power lines, impacting evacuation efforts or emergency response.

The City’s unhoused population is especially vulnerable to the impacts of extreme wind, as they lack adequate shelter during such an event. In addition, the medically fragile are at increased risk due to the potential of power outages affecting critical medical equipment.

The City will be drafting an Extreme Wind Annex to address the city’s response, the cascading hazards that could happen as a result of such an event, and how to adequately plan to support at-risk populations to mitigate impacts from high and sustained wind events.

Flooding
The City has moderate exposure to flooding, mostly due to local creeks and the proximity to larger rivers that could flood during heavy rainfall events and impact homes, transportation corridors, and infrastructure. There are 44 buildings in the 1 percent annual chance floodplain and 1,310 buildings in the 0.2 percent annual chance floodplain. There are five critical bridges in the 1 percent annual chance floodplain and eight critical facilities (banks, daycares, and schools) in the 0.2 percent annual chance floodplain. Table 10-22 identifies critical facilities in the community located in the 1 percent and

0.2 percent annual chance floodplains.

Source: County of Sonoma; California Energy Commission; Caltrans; HIFLD; USACE NID People living in low-lying areas and those living in homes or apartments without proper drainage can be especially vulnerable to flooding, as well as those with access and functional needs that require additional assistance to evacuate.

There are 76 people living in the 1 percent annual chance floodplain, including 12 people living with a disability; 2,089 people live in the 0.2 percent annual chance floodplain, including 349 people living with a disability.

Landslide
The City has low exposure to landslide hazards, and no recent history of such an event within the city limits. However, there are 30 buildings in the moderate landslide susceptibility hazard area, 234 buildings in the high landslide susceptibility hazard area, six critical water tanks in the moderate landslide susceptibility hazard area, and one local bridge in the high landslide susceptibility hazard area. This means the City of Sonoma must plan for the potential of such an event as a result of prolonged heavy rain or nearby seismic activity.

Populations most vulnerable to landslides are those living in moderate to high landslide susceptibility areas and those living in moderate wildfire severity zones. There are 20 people living in the moderate landslide susceptibility hazard area and 364 people living in the high landslide susceptibility hazard area. People with limited communication options can be vulnerable as well, as alerts and requests for assistance may be delayed.

Wildfire
With the recently updated fire risk severity maps, a portion of the City of Sonoma is now in a high fire risk zone, due to the region’s amount of vegetation, risk of prolonged drought conditions, and exposure to high winds. Over the past decade, Sonoma County has experienced multiple presidentially declared wildfires that have threatened homes, prompted evacuations, degraded air quality, and impacted regional safety. While only one of these incidents resulted in evacuation warnings or potential structure impacts within city limits, the broader regional effects have significantly impacted the Sonoma community. These impacts have included poor air quality, disruptions to daily life and local services, increased demand on emergency resources, and heightened public concern. This regional context underscores the importance of continued coordination, preparedness, and public communication efforts within the City of Sonoma.

There are 974 buildings in the moderate fire hazard severity zone, 747 buildings in the high fire hazard severity zone, and 1,564 buildings in the very high fire hazard severity zone. There are 10 critical facilities in the moderate fire hazard severity zone (a bank, daycare, fire station, library, local bridge, Agenda Item #7.6:

Page 105 of 231 ends

Sonoma County Hazard Mitigation Plan
City of Sonoma 10-38
communications towers, school, and shelter), 10 critical facilities in the high fire hazard severity zone (banks, daycares, Coldwater Creek Plant, and communications towers), and 28 critical facilities in the very high fire hazard severity zone (banks, daycares, food distribution, local bridges, Sonoma Valley Community Health Center, municipal halls, Sonoma Police Department, shelters, and water tanks).

Unhoused individuals, people with access and functional needs, older adults, and medically fragile residents (especially those with respiratory conditions) are at increased risk during wildfire incidents.

Residents lacking transportation and those living near busy transportation corridors are also at elevated risk due to the challenges posed by evacuation and the risk of roadways becoming clogged during a large-scale evacuation.

There are 1,706 people living in the moderate fire hazard severity zone, 1,072 people living in the high fire hazard severity zone, and 2,279 people living in the very high fire hazard severity zone.

Potential Impacts from Hazards of Local Concern
Table 10-23 summarizes available quantitative estimates of potential impacts on community assets for dam failure, flood, and earthquake hazards. In the event of a 500‑year earthquake, as many as 164 households could be displaced, 66 people may require shelter, 6.8 percent of the buildings in the City could be damaged, and 84,484 tons of debris could be generated. In the event of a 2,500‑year earthquake, as many as 582 households could be displaced, 238 people may require shelter, 16.2 percent of the buildings in the City could be damaged, and 219,264 tons of debris could be generated.

In the event of a 1 percent annual chance flood, as many as 108 people could be displaced, 56 people may require shelter, and 305 tons of debris could be generated.

Table 10-24. Qualitative Assessment of Impacts for Hazards of Local Concern Hazard Qualitative Local Impacts
Dam Failure Per the above risk assessment findings, dam inundation is not expected to have a direct impact on the people, buildings, or critical facilities located in the City.

Drought Drought conditions can impact Sonoma by reducing water supply, affecting agriculture, and increasing the likelihood of wildfires.

Earthquake Located within an active seismic region, Sonoma is at risk of experiencing earthquakes that could cause disruption to services and structural damage specifically to older buildings constructed prior to current building standards.

Extreme Cold Extreme cold events are rare and typically have minimal impact on the City’s population and infrastructure.

Extreme Heat Periodic heat waves pose health risks, especially to vulnerable populations, and can strain energy and water resources.

Extreme Wind City of Sonoma may occasionally experience strong winds that can cause property damage, power outages, and hazardous conditions.

Flood Flooding from intense rainfall and overflow of nearby waterways can affect residential areas, infrastructure, and transportation.

Landslide Some areas, particularly those with steeper terrain, may be prone to landslides during heavy rain or seismic activity.

Wildfire The City faces significant wildfire risk, given the surrounding vegetation and climate, which can threaten homes, air quality, and safety.

10.9.4 Identified Issues
After review of hazard event history, hazard rankings, hazard location, and current capabilities, the City of Sonoma identified the following risk-related issues for the community:
• The City’s existing Emergency Operations Plan (EOP) lacks dedicated annexes that address the growing threat of extreme heat, extreme cold, and extreme wind events, which require distinct operational strategies.
• The City may need to shelter evacuees from a variety of hazards including dam failure, wildfires, floods, extreme heat or cold, earthquakes, and other emergencies, especially for vulnerable populations such as the unhoused.
• Extreme weather events—including heat waves, cold snaps, and high-wind storms—are becoming more frequent and severe due to climate change. Vulnerable populations, such as people over 65, low-income residents, and individuals with medical conditions, face increased health risks. Additionally, extreme weather can cause power outages, impacting heating and cooling access, and increasing emergency medical responses. • Public facilities that serve as community cooling, heating, or emergency shelters are vulnerable to power outages during multiple hazard events, limiting their effectiveness. • Critical facilities and infrastructure provide essential operations for City staff and the public but can experience power outages, limiting their effectiveness. • Vulnerable populations in mobile homes and older structures are at risk during extreme cold and heat events.

Agenda Item #7.6:

Page 107 of 231 ends

Sonoma County Hazard Mitigation Plan
City of Sonoma 10-40
• Vulnerable populations may not have access to cooling devices during extreme heat events.

Those who are homebound or without transportation may be put at risk attempting to access cooling centers or other public areas.
• Many residents are unaware of the full scope of hazards that pose a risk to the Sonoma Valley community, as well as the necessary preparedness and response measures. Without proper education, individuals may not take proactive steps to reduce their risks, leading to increased damage and potential loss of life during disasters. Vulnerable populations, such as people over 65, low-income families, and non-English-speaking communities, may face additional barriers to accessing life-saving information.
• Public lands near residential areas face increasing wildfire threats and are located within very high fire hazard severity zones. This is a good location for fire breaks, as it buffers the downtown area from wildland areas.
• Some homeowners lack resources or capacity to meet defensible space requirements and may unintentionally create new hazards such as erosion or landslide risk by removing vegetation indiscriminately. Inappropriate vegetation removal can also disrupt local ecosystems and reduce biodiversity, soil stability, and long-term ecological health. • Some of the City's critical infrastructure is in high fire zones, Infrastructure hardening will be required to make this infrastructure resistant to fires. • Evacuation routes in high-risk wildfire zones are vulnerable to road obstructions, downed power lines, and increased congestion during wildfire situations. • Many transportation routes lack proper fire-resistant buffers, thereby increasing the risk of road closures and preventing effective and quick re-population of the evacuated area after a major disaster event.
• Some critical water infrastructure requires seismic retrofit to ensure flow and delivery of potable water to connections.
• Some structures are located below flood elevations or unnecessarily located in high fire hazard areas.
• The City bridge inventory is currently being assessed to determine if the current number of bridges that are inspected by Caltrans every 2 years is adequate or should be increased. All City-owned vehicular and/or pedestrian bridges need to be assessed for seismic and scour vulnerabilities. • Heavy rainfall events are overwhelming existing drainage systems, leading to road closures, potential property damage, and limited access for emergency vehicles. Certain areas within the City of Sonoma are prone to this and a variety of issues arise, including the need for significant emergency response.
• Water courses must be maintained to remain free of obstructions and to protect drainage facilities to conform with the Regional Water Quality Control Board's best management practices. Multijurisdictional effort will be required to meet this goal. Many of these water courses are on private property.
• The City experiences aquifer depletion and reduced local production capacity (independent of Sonoma Water/wholesale aqueduct).

Agenda Item #7.6:

Page 108 of 231 ends

Sonoma County Hazard Mitigation Plan
City of Sonoma 10-41
• The City's wells are aging and with changing hazard risks there is a need for thorough assessment.
• If land movement severs the line to Thornsberry Tank, it is likely to cause severe damage to hillside and water outage to residents in Zone 2 (which is in a high fire hazard area). • City facilities currently have functional vulnerabilities that could lead to loss of staff capabilities in the event of a large scale disaster, power outage, etc. • Various planning documents and codes lack overall cohesion. • There are residential structures located within the 1 percent annual chance floodplain. • Historic resources are an economic and cultural value to the City and when they ae damaged the City prefers that they be repaired rather than demolished. • Some multifamily buildings are not built to current fire code requirements. • Changing risks require continuous evaluation and mitigation efforts. • Details that document significant events (e.g., high water marks, preliminary damage estimates, damage photos, etc.) need to be captured to support future mitigation efforts. • Limited local notification capabilities result in vehicles and residents entering dangerous areas during floods, landslides, extreme wind events that cause downed trees or power lines, and periods of post-earthquake disruptions.
• Limited adoption of rainwater and graywater systems hinders water conservation efforts. • Impervious surfaces reduce groundwater recharge and exacerbate drought and flood risks. • Traditional landscaping contributes to excessive water use and wildfire risk. • Areas of the city lack adequate tree canopy coverage, which exacerbates extreme heat impacts and increases erosion risk.
• Many privately owned residential buildings may have soft-story vulnerabilities, making them susceptible to collapse during seismic events. These structures pose a significant risk to life safety and property, especially in densely populated areas.

• Roadside vegetation projects
• Increased defensible space and vegetation management compliance inspections • Increased education in wildfire prevention and mitigation strategies • Fire District purchase of land for a new fire station facility outside city limits, increasing regional response capability
• Increased training and equipment capacity in swift water rescue

10.10.3 Proposed Hazard Mitigation Actions for the HMP Update The City of Sonoma participated in the mitigation strategy workshop for this HMP to identify appropriate actions to include in a local hazard mitigation strategy. Its comprehensive consideration of all possible activities to address hazards of concern included review of the following FEMA documents:
• FEMA 551 “Selecting Appropriate Mitigation Measures for Floodprone Structures” (March 2007) • FEMA “Mitigation Ideas—A Resource for Reducing Risk to Natural Hazards” (January 2013) • FEMA Hazard Mitigation Assistance Program and Policy Guide (July 2024) The action worksheets included at the end of this annex list the mitigation actions that the City would like to pursue in the future to reduce the effects of hazards. The actions are dependent upon available funding (grants and local match availability) and may be modified or omitted at any time based on the occurrence of new hazard events and changes in City priorities.

Action 2026-SonomaCity-16. Stormwater Management Improvements Lead Agency: City of Sonoma Public Works
Supporting Agencies: Sonoma Water, Sonoma County Public Works, Sonoma County Emergency Management
Hazard(s) of Concern: Flooding
Description of the Problem: Heavy rainfall events are overwhelming existing drainage systems, leading to road closures, potential property damage, and limited access for emergency vehicles. Certain areas within the City of Sonoma are prone to this and a variety of issues arise including the need for significant emergency response.

Description of the Solution: Improved drainage, reduced flood risk, enhanced emergency response.

Target hazard areas historically known to flood and work with internal and external stakeholders and property owners to improve infrastructure to mitigate frequency of events.

Assess repetitive flood hazard areas, complete video inspection of existing storm drains to accomplish condition assessment. Complete modifications as identified.

Estimated Cost: Medium
Potential Funding Sources: FEMA FMA, State Water Resources Control Board Grants Implementation Timeline: 1-5 years
Objectives Met: 1,2,4,6,9,10,12,13
Benefits: Less property damage, safer roads, faster response times, decrease in calls for service
Impact on Socially Vulnerable
Populations:

Reduces risk in low-income flood-prone areas.

Impact on Future Development: May require zoning adjustments.

Impact on Critical

Action 2026-SonomaCity-17. Ordinance Enforcement
Lead Agency: City of Sonoma Public Works
Supporting Agencies: Other Sonoma County Agencies
Hazard(s) of Concern: Flood, Landslide
Description of the Problem: Watercourses must be maintained to remain free of obstructions and to protect drainage facilities to conform with the Regional Water Quality Control Board's Best Management Practices. Multi-jurisdictional effort will be required to meet this goal. Many of these watercourses are on private property.

Description of the Solution: Hold multi-jurisdictional event whose goal is to define current issues with maintaining watercourses that will lead to fewer obstructions in critical drainage facilities.

Enforce provisions under creek protection, stormwater management, and discharge control ordinances designed to keep watercourses free of obstructions and to protect drainage facilities to conform with the Regional Water Quality Control Board's Best Management Practices.

Estimated Cost: Low
Potential Funding Sources: HMGP, PDM, FMA, FSR, County Zone 3A, Staff Time, General Funds Implementation Timeline: 1-5 years
Objectives Met: 1,2,6,8,10,11,13
Benefits: Conformance with Regional Water Quality Control Board bmps. Reduce risk of flooding due to clogged drainage.

Impact on Socially Vulnerable
Populations:

Reduces risk in low-income flood-prone areas.

Impact on Future Development: Future development subject to the enforced applicable creek protection and stormwater management provisions during design and constructions phases.

Impact on Critical
Facilities/Lifelines:

Prevents flooding in neighborhoods, around critical facilities, and across evacuation routes.
