INTRODUCTION

BACKGROUND
The Federal Emergency Management Agency (FEMA) encourages multi-jurisdictional planning for hazard mitigation. All participating jurisdictions must meet the requirements of Chapter 44 of the Code of Federal Regulations (44 CFR):
“Multi-jurisdictional plans (e.g. watershed plans) may be accepted, as appropriate, as long as each jurisdiction has participated in the process and has officially adopted the plan.” (Section 201.6(a)(4)).

For the Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021, a planning partnership was formed to leverage resources and to meet requirements of the federal Disaster Mitigation Act for as many eligible local governments as possible. The Disaster Mitigation Act defines a local government as follows:
“Any county, municipality, city, town, township, public authority, school district, special district, intrastate district, council of governments (regardless of whether the council of governments is incorporated as a nonprofit corporation under State law), regional or interstate government entity, or agency or instrumentality of a local government; any Indian tribe or authorized tribal organization, or Alaska Native village or organization; and any rural community, unincorporated town or village, or other public entity.”
In addition, federally recognized tribes may participate in local/tribal multi-jurisdictional plans as long as the requirements of Section 201.7 of 44 CFR are met for tribal components of the plan.

Two types of planning partners participated in this process for the Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021, with distinct needs and capabilities:
• Incorporated municipalities
• Special districts
Each participating planning partner prepared a jurisdiction-specific annex to this plan. These annexes, as well as information on the process by which they were created, are contained in this volume.

THE PLANNING PARTNERSHIP
Initial Solicitation and Letters of Intent
A planning team made up of Sonoma County and consultant staff solicited the participation of all eligible municipalities and special districts at the outset of this project. A kickoff meeting was held on June 10, 2020, to identify potential stakeholders and planning partners for this process. The purpose of the meeting was to introduce Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes xii
the planning process to jurisdictions in the County that could have a stake in the outcome of the planning effort.

All eligible local governments in the planning area were invited to attend. The goals of the meeting were as follows:
• Provide an overview of the Disaster Mitigation Act.
• Review the 2016 Sonoma County Operational Area Hazard Mitigation Plan and planning partnership • Outline the work plan for this hazard mitigation plan. • Describe the benefits of multi-jurisdictional planning. • Outline planning partner expectations.
• Solicit planning partners.
• Solicit volunteers/recommendations for the steering committee.

Local governments wishing to join the planning effort were asked to provide the planning team with a “letter of intent to participate” that agreed to the planning partner expectations (see Appendix A) and designated a point of contact for their jurisdiction. In all, the planning team received formal commitment from 13 planning partners in addition to the County. A map showing the location of participating special purpose districts is provided at the end of this introduction. Maps showing risk assessment results for participating cities are provided in the individual annexes for each city. Risk assessment maps for all planning areas countywide are provided in Volume 1 of this hazard mitigation plan.

Planning Partner Expectations
The planning team developed the following list of planning partner expectations, which were provided and discussed at the kickoff meeting (see Appendix A for details):
• Complete a “letter of intent to participate.”
• Designate a lead point of contact for this effort.
• Support and participate in the selection and function of the Steering Committee. • Provide support required to implement the public involvement strategy. • Participate in the process through opportunities such as:
 Steering Committee meetings
 Public meetings or open houses
 Workshops and planning partner specific training sessions  Public review and comment periods prior to adoption.
• Attend the mandatory jurisdictional annex workshop.
• Complete the jurisdictional annex.
• Perform a “consistency review” of all technical studies, plans and ordinances specific to hazards. • Review the risk assessment and identify hazards and vulnerabilities specific to the jurisdiction. • Review and determine if the mitigation recommendations chosen in Volume 1 will meet the needs of the jurisdiction.

Introduction
xiii
• Create an action plan that identifies each project, who will oversee the task, how it will be financed, and when it is estimated to occur.
• Formally adopt the hazard mitigation plan.

By adopting this plan, each planning partner also agrees to the plan implementation and maintenance protocol established in Volume 1. Failure to meet these criteria may result in a partner being dropped from the partnership by the Steering Committee, and thus losing eligibility under the scope of this plan.

Final Coverage
All of the following planning partners submitted letters of intent to participate fully met the participation requirements for this update, completed an annex template, and will be covered by the current hazard mitigation plan upon FEMA approval and adoption by their governing bodies:
• County of Sonoma
• City of Cotati
• City of Santa Rosa
• City of Sonoma
• Town of Windsor
• Cloverdale Fire Protection District
• North Sonoma Coast Fire Protection District
• Northern Sonoma County Fire Protection District
• Rancho Adobe Fire Protection District
• Sonoma Valley Fire Protection District
• Timber Cove Fire Protection District
• Gold Ridge Resource Conservation District
• Sonoma Resource Conservation District
• Sonoma County Agricultural Preservation & Open Space District Linkage Procedures
Eligible local jurisdictions that did not participate in development of this multi-jurisdictional plan may comply with Disaster Mitigation Act requirements by linking to this plan following procedures outlined in Appendix B.

PARTNER ANNEX DEVELOPMENT
Capability Assessment
All participating jurisdictions compiled an inventory and analysis of existing authorities and capabilities called a “capability assessment.” A capability assessment creates an inventory of a jurisdiction’s mission, programs, and policies, and evaluates its capacity to carry them out. This assessment identifies potential gaps in the jurisdiction’s capabilities. If the capability assessment identified an opportunity to add a missing core capability or expand an Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes xiv
existing one, then doing so has been selected as an action in the jurisdiction’s action plan. The sections below describe the specific capabilities evaluated under the assessment.

Planning and Regulatory Capabilities
Jurisdictions can develop policies and programs and implement rules and regulations to protect and serve residents. Local policies are typically identified in planning documents, implemented via a local ordinance, and enforced by a governmental body. Because the planning and regulatory authority of municipal partners is generally broader than that of special-purpose districts, the assessment of these capabilities is more detailed for the municipal partners.

Development and Permitting Capability
This set of capabilities is not applicable to special purpose districts and was assessed only for municipal partners (cities and the County). Municipal jurisdictions regulate land use through the adoption and enforcement of zoning, subdivision, and land development ordinances, building codes, building permit ordinances, floodplain, and stormwater management ordinances. When effectively prepared and administered, these regulations can lead to hazard mitigation.

Fiscal Capabilities
Assessing a jurisdiction’s fiscal capability provides an understanding of the ability to fulfill the financial needs associated with hazard mitigation projects. This assessment identifies both outside resources, such as grant- funding eligibility, and local jurisdictional authority to generate internal financial capability, such as through impact fees.

Administrative and Technical Capabilities
Without appropriate personnel, the mitigation strategy may not be implemented. Administrative and technical capabilities focus on the availability of personnel resources responsible for implementing all the facets of hazard mitigation. These resources include technical experts, such as engineers and scientists, as well as personnel with capabilities that may be found in multiple departments, such as grant writers.

Education and Outreach Capability
Regular engagement with the public on issues regarding hazard mitigation provides an opportunity to directly interface with community members. Assessing this outreach and education capability illustrates the connection between the government and community members, which opens a two-way dialogue that can result in a more resilient community based on education and public engagement.

Compliance with National Flood Insurance Program Requirements The National Flood Insurance Program (NFIP) is not available to special purpose districts, so this set of capabilities was assessed only for municipal partners (cities and the County). Flooding is the costliest natural hazard in the United States and homeowners face increasingly high flood insurance premiums. Community participation in the NFIP opens up opportunity for additional grant funding associated specifically with flooding issues. Assessment of a jurisdiction’s current NFIP status and compliance provides a greater understanding of the local flood management program, opportunities for improvement, and available grant funding opportunities.

Introduction
xv
Participation and Classification in Other Programs
Other programs, such as the Community Rating System, Storm/Tsunami Ready, and Firewise USA, can enhance a jurisdiction’s ability to mitigate, prepare for, and respond to natural hazards. These programs indicate a jurisdiction’s desire to go beyond minimum requirements set forth by local, state, and federal regulations in order to create a more resilient community. These programs complement each other by focusing on communication, mitigation, and community preparedness to save lives and minimize the impact of natural hazards on a community. The programs reviewed here are applicable to municipal partners only so they are not included in the capability assessments for special-purpose districts.

Adaptive Capacity
An adaptive capacity assessment evaluates a jurisdiction’s ability to anticipate impacts from future conditions. By looking at public support, technical adaptive capacity, and other factors, jurisdictions identify their core capability for resilience against issues such as sea level rise. The adaptive capacity assessment provides jurisdictions with an opportunity to identify areas for improvement by ranking their capacity high, medium, or low.

Mitigation Action Plan Development
Risk Ranking
In the risk-ranking exercise, each planning partner was asked to review the ranked risk specifically for its jurisdiction, based on the impact on its population and/or facilities. Municipalities based this ranking on probability of occurrence and the potential impact on people, property, and the economy. Special purpose districts based this ranking on probability of occurrence and the potential impact on their constituency, their vital facilities, and the facilities’ functionality after an event. The methodology followed that used for the countywide risk ranking presented in Volume 1. The objectives of this exercise were to familiarize the partnership with how to use the risk assessment as a tool to support other planning and hazard mitigation processes and to help prioritize types of mitigation actions that should be considered. Hazards that were ranked as “high” and “medium” for each jurisdiction as a result of this exercise were considered to be priorities for identifying mitigation actions, although jurisdictions also identified actions to mitigate “low” ranked hazards, as appropriate.

Information Reviewed to Develop Action Plan
The tool kits were used during the workshops and in follow-up work conducted by the planning partners. A large portion of the workshop focused on how the tool kit should be used to develop the mitigation action plan.

Planning partners were specifically asked to review the following to assist in the identification of actions:
• The Jurisdiction’s Capability Assessment—Reviewed to identify capabilities that the jurisdiction does not currently have but should consider pursuing or capabilities that should be revisited and updated to include best available information; also reviewed to determine how existing capabilities can be leveraged to increase or improve hazard mitigation in the jurisdiction. • The Jurisdiction’s National Flood Insurance Program Compliance Table—Reviewed to identify opportunities to increase floodplain management capabilities. • The Jurisdiction’s Review of Its Adaptive Capacity for Climate Change—Reviewed to identify ways to leverage or continue to improve existing capacities and to improve understanding of other capacities.

Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes xvi
• The Jurisdiction’s Identified Opportunities for Future Integration—Reviewed to identify specific integration actions to be included in the mitigation strategy. • Jurisdiction-Specific Vulnerabilities—Reviewed to identify actions that will help reduce known vulnerabilities.
• The Mitigation Best Practices Catalog—Reviewed to identify actions that the jurisdiction should consider including in its action plan.
• Public Input—Reviewed to identify potential actions and community priorities.

Action Plan Prioritization
The actions recommended in the action plan were prioritized based on the following factors:
• Cost and availability of funding
• Benefit, based on likely risk reduction to be achieved • Number of plan objectives achieved
• Timeframe for project implementation
• Eligibility for grand funding programs
Two priorities were assigned for each action:
• A high, medium or low priority for implementing the action • A high, medium or low priority for pursuing grant funding for the action.

The sections below describe the analysis of benefits and costs and the assignment of the two priority ratings.

Benefit/Cost Review
The action plan must be prioritized according to a benefit/cost analysis of the proposed actions (44 CFR, Section 201.6(c)(3)(iii)). For this hazard mitigation plan, a qualitative benefit-cost review was performed for each action by assigning ratings for benefit and cost as follows:
• Cost:
 High—Existing funding will not cover the cost of the action; implementation would require new revenue through an alternative source (for example, bonds, grants, and fee increases).  Medium—The action could be implemented with existing funding but would require a re- apportionment of the budget or a budget amendment, or the cost of the action would have to be spread over multiple years.
 Low—The action could be funded under the existing budget. The action is part of or can be part of an ongoing existing program.
• Benefit:
 High—Action will provide an immediate reduction of risk exposure for life and property.  Medium—Action will have a long-term impact on the reduction of risk exposure for life and property, or action will provide an immediate reduction in the risk exposure for property.  Low—Long-term benefits of the action are difficult to quantify in the short term.

Introduction
xvii
To assign priorities, each action with a benefit rating equal to or higher than its cost rating (such as high benefit/medium cost, medium benefit/medium cost, medium benefit/low cost, etc.) was considered to be cost- beneficial. This is not the detailed level of benefit/cost analysis required for some FEMA hazard-related grant programs. Such analysis would be performed at the time a given action is being submitted for grant funding.

Implementation Priority
Implementation priority ratings were assigned as follows:
• High Priority—An action that meets multiple objectives, has benefits that exceed costs, and has a secured source of funding. Action can be completed in the short term (1 to 5 years). • Medium Priority—An action that meets multiple objectives, has benefits that exceed costs, and is eligible for funding though no funding has yet been secured for it. Action can be completed in the short term (1 to 5 years), once funding is secured. Medium-priority actions become high-priority actions once funding is secured.
• Low Priority—An action that will mitigate the risk of a hazard, has benefits that do not exceed the costs or are difficult to quantify, has no secured source of funding, and is not eligible for any known grant funding. Action can be completed in the long term (1 to 10 years). Low-priority actions may be eligible for grant funding from programs that have not yet been identified.

Grant Pursuit Priority
Grant pursuit priority ratings were assigned as follows:
• High Priority—An action that meets identified grant eligibility requirements, has high benefits, and is listed as high or medium implementation priority; local funding options are unavailable or available local funds could be used instead for actions that are not eligible for grant funding. • Medium Priority—An action that meets identified grant eligibility requirements, has medium or low benefits, and is listed as medium or low implementation priority; local funding options are unavailable. • Low Priority—An action that has not been identified as meeting any grant eligibility requirements.

Classification of Actions
Each recommended action was classified based on the hazard it addresses and the type of mitigation it involves.

Mitigation types used for this classification are as follows:
• Prevention—Government, administrative or regulatory actions that influence the way land and buildings are developed to reduce hazard losses. Includes planning and zoning, floodplain laws, capital improvement programs, open space preservation, and stormwater management regulations. • Property Protection—Modification of buildings or structures to protect them from a hazard or removal of structures from a hazard area. Includes acquisition, elevation, relocation, structural retrofit, storm shutters, and shatter-resistant glass.
• Public Education and Awareness—Actions to inform residents and elected officials about hazards and ways to mitigate them. Includes outreach projects, real estate disclosure, hazard information centers, and school-age and adult education.
• Natural Resource Protection—Actions that minimize hazard loss and preserve or restore the functions of natural systems. Includes sediment and erosion control, stream corridor restoration, watershed Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes xviii
management, forest and vegetation management, wetland restoration and preservation, and green infrastructure.
• Emergency Services—Actions that protect people and property during and immediately after a hazard event. Includes warning systems, emergency response services, and the protection of essential facilities. • Structural Projects—Actions that involve the construction of structures to reduce the impact of a hazard.

Includes dams, setback levees, floodwalls, retaining walls, and safe rooms. • Climate Resiliency—Actions that incorporate methods to mitigate and/or adapt to the impacts of climate change. Includes aquifer storage and recovery activities, incorporating future conditions projections in project design or planning, or actions that specifically address jurisdiction-specific climate change risks, such as sea-level rise or urban heat island effect.
• Community Capacity Building—Actions that increase or enhance local capabilities to adjust to potential damage, to take advantage of opportunities, or to respond to consequences. Includes staff training, memorandums of understanding, development of plans and studies, and monitoring programs.

Annex-Preparation Process
Templates
Templates were created to help the planning partners prepare their jurisdiction-specific annexes. Separate templates were created for the two types of jurisdictions participating in this plan. The templates were created so that all criteria of Section 201.6 of 44 CFR for local governments would be met based on the partners’ capabilities and mode of operation. Separate templates were available for partners updating a previous hazard mitigation plan and those developing a first-time hazard mitigation plan. These templates were deployed in three phases during the course of this plan update process. These phases are described as follows:
• Phase 1—Profile, Trends, Previous Plan Status
 Deployed: November 26, 2020
 Due: December 31, 2020
• Phase 2—Capability Assessment and Information Sources  Deployed: February 19, 2021
 Due: March 29, 2021

1.2 JURISDICTION PROFILE

1.2.1 Location and Features
Sonoma County, the most northerly of the nine counties in the San Francisco Bay Region, is located along the Pacific coastline about 40 miles north of San Francisco and the Golden Gate Bridge. At just over 1,500 square miles, it is the largest of the nine Bay Area counties. Sonoma County is bordered by the Pacific Ocean on the west, Marin County and San Pablo Bay to the south, Solano, Napa and Lake Counties to the east, and Mendocino County to the north.

The climate of Sonoma County is determined by the marine (ocean) airflow and the effects of geography in diverting that airflow. During an average summer there are many days when fog maintains a band of cold air all along the coastline and cold breezes blow a fog bank in through the Petaluma gap northward toward Santa Rosa, and northwestward toward Sebastopol. It also moves around Sonoma Mountain, not quite reaching Glen Ellen.

This fog bank is accompanied by a rapid decrease in temperature which can be as much as 50 ºF. The time of day when this occurs and the duration of the fog designates three distinct major climatic zones: Marine, Coastal Cool, Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 1-2
and Coastal Warm. Several microclimates also exist especially near the borders of the three major zones.

Microclimates can be designated by elevation, air drainage, proximity to mountain peaks, and sun exposure.

Chilling hours (below 45 ºF) range from 700 to 1,850 hours and average 1,300 hours per year.

1.2.2 History
Sonoma County was incorporated in January 1850 as one of California’s original eighteen missions. Before the European settlement, what is today Sonoma County was inhabited by the Pomo, Miwok, and Kashia Indians. In 1812, the Russians established the short-lived Fort Ross along the coast north of the Russian River. Further east, the Sonoma Mission was established during the Mexican period in 1823. Shortly afterwards, Sonoma became the county’s first town, a pueblo, under General Mariano Vallejo. Around the turn of the century, the Russian River developed as a vacation resort, a destination for those in the San Francisco Bay Area. During this time, Santa Rosa also enjoyed an increase in population and importance as the center of finance and county government. Until World War II, the poultry industry, the processing of local fruit, and the production of hops sustained the economy throughout the county. In 1935, Sonoma County ranked tenth in the nation in overall agricultural production. Today the southwestern part of the county continues to support cattle grazing and dairy farms.

Toward the north many of the ranches and orchards have been replaced with acres of vineyards and thriving winery operations that rival Napa County. The Russian River area still caters to vacationers and the cities along the freeway continue to expand to provide housing and services with new subdivisions, business parks, and shopping centers (Sonoma County, 2020).

1.2.3 Governing Body Format
Sonoma County Board of Supervisors sits as the governing board of Sonoma County and of various special jurisdictions such as the Sonoma County Water Agency, the Agricultural Preservation and Open Space District, County Sanitation Districts, and the Community Development Commission. The Board is composed of five supervisors elected from supervisorial districts. Each supervisor serves a four-year term (Sonoma County, 2020).

The Sonoma County Board of Supervisors assumes responsibility for the adoption of this plan; Permit Sonoma and Sonoma County Department of Emergency Management will oversee its implementation.

1.3 CURRENT TRENDS

1.3.1 Population
According to the United States Census Bureau, the population of Sonoma County as of July 2019 was 494,336.

Since 2010, the population has grown at an average annual rate of 2.2 percent.

1.3.2 Development
Since the completion of the last Hazard Mitigation Plan in 2017, development has continued at a steady pace with an average of approximately 4,000 completed building permits per year. Much of this activity is improvements to existing structures and residences. The approximate number of completed new residential units has increased over time from 235 in 2017 to 550 in 2019. Reconstruction of residences destroyed by wildfires during the three-year time is well underway and is a significant percentage of development activity.

Table 1-2 summarizes development trends in the performance period since the preparation of the previous hazard mitigation plan, as well as expected future development trends.

Table 1-2. Recent and Expected Future Development Trends Criterion Response
Has your jurisdiction annexed any land since
the preparation of the previous hazard
mitigation plan?
No
If yes, give the estimated area annexed and
estimated number of parcels or structures.

In general, the county loses land to incorporated cities as a result of annexation

Is your jurisdiction expected to annex any
areas during the performance period of this
plan?
No
If yes, describe land areas and dominant uses. N/A
If yes, who currently has permitting authority
over these areas?
N/A
Are any areas targeted for development or
major redevelopment in the next five years?
Yes
If yes, briefly describe, including whether any
of the areas are in known hazard risk areas
The County is currently preparing a draft EIR to analyze the possible rezoning of 59 sites countywide for higher-density housing to add to the next Housing Element site inventory. The EIR identified potentially significant wildfire risk-related impacts due to the proximity of some of the potential sites to moderate, high, and very high fire hazard severity zones.

The County also has several specific plans in progress at the time of this plan’s preparation. An update of the Airport Industrial Area Specific Plan addresses the development of several opportunity sites within the urbanized area. Some sites within the planning area are subject to flood risks.

The Springs Specific Plan, in progress for a 180-acre area in the Sonoma Valley, contemplates future development in areas that may be subject to wildfire and landslide risk.

The area addressed by the Sonoma Developmental Center Specific Plan underway includes historic structures that may need seismic retrofitting.

How many permits for new construction were
issued in your jurisdiction since the
preparation of the previous hazard mitigation
plan?
2015 2016 2017 2018 2019
Single Family N/A N/A 230 193 506

Provide the number of new-construction
permits for each hazard area or provide a
qualitative description of where development
has occurred.

With the excepting of development permits within the FEMA designated Special Flood Hazard Area pursuant to the requirements for the National Flood Insurance program, Sonoma County does not currently track development permits by hazard area.

Describe the level of buildout in the
jurisdiction, based on your jurisdiction’s
buildable lands inventory. If no such inventory
exists, provide a qualitative description.

New residential and building potential is generally limited. The majority of the County is under agricultural or rural zoning without access to sewer and water services.

Limited residential potential exists within sanitation district boundaries. Periodically, the County will rezone sites with access to services as they become available to create more potential housing sites.

1.4 CAPABILITY ASSESSMENT
This section describes an assessment of existing capabilities for implementing hazard mitigation strategies. The introduction at the beginning of this volume of the hazard mitigation plan describes the components included in Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 1-4
the capability assessment and their significance for hazard mitigation planning. This section summarizes the following findings of the assessment:
• An assessment of planning and regulatory capabilities is presented in Table 1-3. • Development and permitting capabilities are presented in Table 1-4. • An assessment of fiscal capabilities is presented in Table 1-5. • An assessment of administrative and technical capabilities is presented in Table 1-6. • An assessment of education and outreach capabilities is presented in Table 1-7. • Information on National Flood Insurance Program (NFIP) compliance is presented in Table 1-8. • Classifications under various community mitigation programs are presented in Table 1-9. • The community’s adaptive capacity for the impacts of climate change is presented in Table 1-10.

Findings of the capability assessment were reviewed to identify opportunities to expand, initiate or integrate capabilities to further hazard mitigation goals and objectives. Where such opportunities were identified and determined to be feasible, they are included in the action plan. The “Analysis of Mitigation Actions” table in this annex identifies these as community capacity building mitigation actions.

1.5 INTEGRATION REVIEW
For hazard mitigation planning, “integration” means that hazard mitigation information is used in other relevant planning mechanisms, such as general planning and capital facilities planning, and that relevant information from those sources is used in hazard mitigation. This section identifies where such integration is already in place, and where there are opportunities for further integration in the future. Resources listed at the end of this annex were used to provide information on integration. The progress reporting process described in Volume 1 of the hazard mitigation plan will document the progress of hazard mitigation actions related to integration and identify new opportunities for integration.

1.5.1 Existing Integration
Some level of integration has already been established between local hazard mitigation planning and the following other local plans and programs:
• County’s Emergency Operation Plan

1. Sonoma County
1-11
• General Plan pursuant to AB2140
• Sonoma County Op Area Hazardous Material Incident Response Plan • Sonoma County Oil Spill Contingency Plan
• Dam Inundation Contingency Plan
• 2016 Sonoma County Community Wildfire Protection Plan • Sonoma County General Plan

1.5.2 Opportunities for Future Integration
The capability assessment presented in this annex identified the following plans and programs that do not currently integrate hazard mitigation information but provide opportunities to do so in the future:
• Future General Plan updates
• Future Specific or Area Plans or updates to existing plans • County Capital Facilities Planning
• Sonoma County Five-Year Strategic Plan
• Local Coastal Plan
• Update to the 2016 Sonoma County Community Wildfire Protection Plan which is occurring during preparation of this plan.

1.6.2 Hazard Risk Ranking
The Risk Assessment for the unincorporated area of the County has been segregated into 5 areas designated by County Supervisor District. Tables 1-12a, to 1-12e show the risk ranking results by Supervisorial District; Table 1-12f presents the aggregate ranking for the entire unincorporated of the County. These are hazard rankings of all hazards of concern for which this hazard mitigation plan provides complete risk assessments. As described in detail in Volume 1, the ranking process involves an assessment of the likelihood of occurrence for each hazard, along with its potential impacts on people, property, and the economy. Mitigation actions target hazards with high and medium rankings.

1.6.3 Jurisdiction-Specific Vulnerabilities
Volume 1 of this hazard mitigation plan provides complete risk assessments for each identified hazard of concern.

This section provides information on a few key vulnerabilities for the jurisdiction. Available jurisdiction-specific risk maps of the hazards are provided at the end of this annex.

Repetitive Loss Properties
Repetitive loss records are as follows:
• Number of FEMA-identified Repetitive-Loss Properties: 904 as of 3/28/2021 • Number of FEMA-identified Severe-Repetitive-Loss Properties: 261 as of 3/28/2021 • Number of Repetitive-Loss Properties or Severe-Repetitive-Loss Properties that have been mitigated:

Unknown at this time.

Other Noted Vulnerabilities
The following jurisdiction-specific issues have been identified based on a review of the results of the risk assessment, public involvement strategy, and other available resources:
• A lack of County facilities and resources outside of the central Santa Rosa area limits the capacity of the County to support and coordinate response efforts in locations that have been historically isolated by disaster events.
• Community disaster preparedness education and training efforts have not been completely successful in identifying and reaching individuals with access and functional needs or communities facing economic or cultural barrier challenges (ex. migrant farm laborers) Mitigation actions addressing these issues were prioritized for consideration in the action plan in this annex.

2.2 JURISDICTION PROFILE

2.2.1 Location and Features
The City of Cotati is an incorporated city in Sonoma County, California, U.S., located about 45 mi (70 km) north of San Francisco in the U.S. 101 corridor between the cities of Rohnert Park and Petaluma.

The city has a total area of 1.89 sq mi (4.9 km2), 0.53% of which is water.

The city is about 17 mi (27 km) from the Pacific Ocean. It lies entirely in the drainage basin of the Laguna de Santa Rosa (river). The Petaluma River watershed begins just south of town. To the west is the Stemple Creek watershed. The sources of all three watercourses lie in the hilly area between Stony Point Road and U.S. 101, just west of town.

A gap in the coastal ridges near Petaluma often allows coastal fog to reach Cotati in the summer, giving it a marine climate that is noticeably cooler and less sunny than the "coastal" climates of nearby Santa Rosa and Sebastopol. Cotati averages fewer than 800 hours per growing season in the 70–90°F range.

Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 2-2

2.2.2 History
The City of Cotati was incorporated July 2, 1963, less than a year after the incorporation of the lands north of town to form Rohnert Park; voters approved (by a 284 to 41 margin) incorporation of Cotati as a separate city.

2.2.3 Governing Body Format
The City of Cotati is governed by a five-member city council. The City consists of six departments:

Administrative Services, Community Development, Public Works/Engineering, Police, and the City Manager's Office. The City Council assumes responsibility for the adoption of this plan; the City Manager will oversee its implementation.

2.3 CURRENT TRENDS

2.3.1 Population
According to California Department of Finance, the 2021 estimate for City of Cotati was 7429, a drop of 1 percent from the previous year.

2.3.2 Development
Table 2-2 summarizes development trends in the performance period since the preparation of the previous hazard mitigation plan, as well as expected future development trends.

2.4 CAPABILITY ASSESSMENT
This section describes an assessment of existing capabilities for implementing hazard mitigation strategies. The introduction at the beginning of this volume of the hazard mitigation plan describes the components included in the capability assessment and their significance for hazard mitigation planning.

Findings of the capability assessment were reviewed to identify opportunities to expand, initiate or integrate capabilities to further hazard mitigation goals and objectives. Where such opportunities were identified and determined to be feasible, they are included in the action plan. The “Analysis of Mitigation Actions” table in this annex identifies these as community capacity building mitigation actions. The findings of the assessment are presented as follows:
• An assessment of legal and regulatory capabilities is presented in Table 2-3. • Development and permitting capabilities are presented in Table 2-4. • An assessment of fiscal capabilities is presented in Table 2-5. • An assessment of administrative and technical capabilities is presented in Table 2-6. • An assessment of education and outreach capabilities is presented in Table 2-7. • Information on National Flood Insurance Program (NFIP) compliance is presented in Table 2-8. • Classifications under various community mitigation programs are presented in Table 2-9. • The community’s adaptive capacity for the impacts of climate change is presented in Table 2-10.

A majority of the existing parcels within the City of Cotati have some level of development on them. The exception to this, is a few larger commercial and residential parcels on the west side of the City and some larger residential and agricultural properties toward the south end of the City. However, many of these previously developed properties are significantly under-developed based on their current land use designations, or the existing development is nearing the end of its functional life and is in need to significant investment to update the structures or re- develop the parcels. The City of Cotati General Plan does not include a buildable lands inventory.

2.5 INTEGRATION REVIEW
For hazard mitigation planning, “integration” means that hazard mitigation information is used in other relevant planning mechanisms, such as general planning and capital facilities planning, and that relevant information from those sources is used in hazard mitigation. This section identifies where such integration is already in place, and where there are opportunities for further integration in the future. Resources listed at the end of this annex were used to provide information on integration. The progress reporting process described in Volume 1 of the hazard mitigation plan will document the progress of hazard mitigation actions related to integration and identify new opportunities for integration.

2.5.1 Existing Integration
Some level of integration has already been established between local hazard mitigation planning and the following other local plans and programs:
• Sonoma County HMP
• Rohnert Park HMP
• Sonoma Water HMP
• City’s Capital Improvement Plan
• City’s General Plan

2.5.2 Opportunities for Future Integration
The capability assessment presented in this annex identified the following plans and programs that do not currently integrate hazard mitigation information but provide opportunities to do so in the future:
• Rancho Adobe Fire Strategic Plan
• Laguna Waste Water HMP
• Sonoma County HMP
• Location tracking of building development in specific hazard areas Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 2-10

3.2 JURISDICTION PROFILE

3.2.1 Location and Features
The City of Santa Rosa is in central Sonoma County, located approximately 55-miles north of San Francisco along US Highway 101 and 20 air miles from the Pacific Ocean. Santa Rosa is bisected by US Highway 101, which runs north to south through the City and State Route (SR) 12 which runs east to west across the City, Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 3-2
roughly dividing Santa Rosa into quadrants. Santa Rosa is bordered by unincorporated Sonoma County on most sides. Sebastopol is to the southwest of the City and Rohnert Park is located approximately eight-miles due south.

Prominent terrain features east of the City include Bennett Peak, Mount Hood, and Sonoma and Taylor Mountains. Santa Rosa is the largest city in Sonoma County with an urban growth boundary (UGB) that spans

42.81-square-miles.

Santa Rosa is in the California region known as the Coast Ranges geomorphic province and lies in the Santa Rosa Plain to the east of the Laguna de Santa Rosa catchment basin which is a major tributary of the Russian River watershed.

The City is home to the Santa Rosa Junior College, Keysight Technologies, La Tortilla Factory, Amy’s Kitchen, the Charles M. Schulz Museum, Luther Burbank Home & Gardens, the first Nissan green auto dealership in the United States, Medtronic’s Aortic and Peripheral Disease Management and Coronary and Structural Heart Disease Management business units, and many world-renowned wineries and breweries.

According to the Köppen climate classification, Santa Rosa has a warm-summer Mediterranean climate with cool, wet winters and warm, dry summers. Fog and low overcast often move in from the Pacific Ocean during the mornings and evenings usually clearing up to warm, sunny weather by late morning or noon. Santa Rosa’s average annual rainfall is 32.20-inches falling on 74 days annually.

3.2.2 History
Santa Rosa has a rich history and cultural heritage. Santa Rosa was a site of Native American habitation beginning approximately 7,000 years ago. The Pomo, Miwok, and Wappo Indians populated the area before Spanish settlement in the early 1800s. The first deeded land was held as the Rancho Cabeza de Santa Rosa and was given to Señora Maria Ignacia Lopez de Carrillo by Spanish authorities in 1841. The Gold Rush, along with California’s statehood, initially brought an influx of travelers along the roads past Santa Rosa. The region’s rich soils drew in numerous passersby creating a flourishing agricultural community. Commercial ventures followed to support the new economy creating the City’s town square in the early 1850s.

In 1867, the Sonoma County’s Board of Supervisors recognized Santa Rosa as an incorporated city and in 1868, the state officially confirmed the incorporation. Santa Rosa is the County seat.

According to the US Census, in 1870 Santa Rosa was the eighth largest city in California, and the county seat of one of the most populous counties in the state. Growth and development after that was generally steady but not rapid. The City continued to grow when other early population centers declined or stagnated, but by 1900, it was being overtaken by many of the other newer population centers in the San Francisco Bay Area and Southern California. The 1906 San Francisco Earthquake sent Santa Rosa into a period of economic downturn but had little effect on the population. Although the town reconstructed most decimated buildings, the Great Depression two decades later further stymied growth and economic development.

Santa Rosa grew substantially following World War II with wartime workers flocking to the Bay Area. The City was also a convenient location for San Francisco travelers bound for the Russian River, and population increased by two-thirds between 1950 and 1970. Between 1970 and 2000, Santa Rosa grew by approximately 3,000 residents a year—triple the average growth during the previous 20 years. Most of this growth was in new suburban neighborhoods to the north, west, and south of downtown, with additional suburban and rural growth along the hillsides and valleys to the east and northeast. Between 2000 and 2010, Santa Rosa grew at an average

3. City of Santa Rosa
3-3
of 2,000 residents a year, but growth slowed to an average of less than 900 new residents per year between 2010 and 2016. The population has decreased approximately two percent between 2017 and 2020.

In October 2017, approximately five percent of Santa Rosa’s homes were destroyed in the Tubbs and Nuns wildfires. Three years later approximately 50-percent of homes have been rebuilt and another 30-percent are in some phase of the rebuild process. Twenty percent, or roughly 500 parcels, are still inactive in the rebuild areas.

As of September 15, 2020, 31-percent of the inactive parcels had been sold. It is expected that most outstanding parcels will eventually submit a permit to rebuild, but due to a variety of circumstances, these may manifest at different times. In September 2020, the Glass Fire destroyed an additional 34 housing units and damaged 23 residential units in eastern Santa Rosa.

Santa Rosa has remained an economic and cultural center for Sonoma County in the more than 150 years since inception. The rich agricultural setting that initially drew settlers to the area has continued to flourish and is a center for the tourism economy surrounding the region’s world-renowned wineries and breweries.

3.2.3 Governing Body Format
The City of Santa Rosa is governed by a seven-person City Council (Council). The Council elects one of its members to serve as Mayor, the executive head of the City; and appoints a City Manager, the administrative head of the City. The City consists of 17 departments/divisions: the City Attorney’s Office, the City Manager’s Office, Communications &Intergovernmental Relations, Community Engagement, Finance, Fire, Housing & Community Services, Human Resources, Information Technology, Parking, Planning and Economic Development, Police, Real Estate Services, Recreation & Parks, Transportation and Public Works, and Water.

The City Council assumes responsibility for the adoption of this plan; and the City Manager will oversee its implementation.

3.3 CURRENT TRENDS

3.3.1 Population
According to the California Department of Finance, the population of Santa Rosa as of January 2020 was 173,628. The City experienced small but steady population gains between the years 2000 and 2016, growing under one percent per year on average. From January 2017 through January 2020, Santa Rosa experienced a two- percent overall population loss but remains the fifth most populous San Francisco Bay Area city.

3.3.2 Development
Anticipated development levels for Santa Rosa are in the lower-moderate to moderate range consisting primarily of residential development. Most recent development has been infill. The City does not have vast tracks of vacant land for residential or industrial subdivision development.

The City of Santa Rosa adopted its General Plan in November of 2009 and is currently working on a comprehensive update which will focus on issues of the greatest concern to the community including how to make the City even more sustainable, resilient, healthy, and inclusive. City actions, such as those relating to land use, annexations, zoning, and capital improvements, must be consistent with the plan. Future growth and development in the City will be managed as identified in the General Plan.

Residential and non-residential growth has occurred in each of the City’s four quadrants since the last Plan update. New residential development within the Wildland Urban Interface includes the Round Barn Village subdivision, a 237-unit multi-family residential development of which approximately 10-percent is currently in construction and Canyon Oaks, a 96-unit condominium project which has been completed. There has been no development in other hazard areas.

Describe the level of buildout in the
jurisdiction, based on your jurisdiction’s
buildable lands inventory. If no such inventory
exists, provide a qualitative description.

The City of Santa Rosa is relatively built out with well-established residential neighborhoods at lower densities than the greater San Francisco Bay Area. Low density, primarily single-family residential is the predominant land use in the city.

Commercial uses are generally located in the heart of Santa Rosa and along US Highway 101 (Highway 101), with 15 unique commercial districts in addition to Downtown Santa Rosa, which operates as a mixed-use district. Over half of all commercial in the City is strip retail. Industrial uses are generally situated in the northern and southern outskirts of Santa Rosa, often near Highway 101, and occupy only about four percent of the City’s land area.

3.5 INTEGRATION REVIEW
For hazard mitigation planning, “integration” means that hazard mitigation information is used in other relevant planning mechanisms, such as general planning and capital facilities planning, and that relevant information from those sources is used in hazard mitigation. This section identifies where such integration is already in place, and where there are opportunities for further integration in the future. Resources listed at the end of this annex were used to provide information on integration. The progress reporting process described in Volume 1 of the hazard mitigation plan will document the progress of hazard mitigation actions related to integration and identify new opportunities for integration.

3.5.1 Existing Integration
Some level of integration has already been established between local hazard mitigation planning and the following other local plans and programs:
• Capital Improvement Plan—The Capital Improvement Plan includes projects that can help mitigate potential hazards. The City will act to ensure consistency between the Hazard Mitigation Plan and the current and future capital improvement plans. The Hazard Mitigation Plan may identify new possible funding sources for capital improvement projects and may result in modifications to proposed projects based on results of the risk assessment.
• Building Code and Fire Code—The City’s adoption of the 2019 California Building and Fire Codes incorporated local modifications to account for the climatic, topographic, and geologic conditions that exist in the City.
• General Plan—The General Plan includes a “Noise and Safety” element to protect the community from unreasonable risk by establishing policies and actions to avoid or minimize the following hazards:

Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 3-12
 Geologic and seismic hazards
 Fire hazards
 Hazardous materials
 Flood control
The General Plan’s “Open Space and Conservation” element includes goals and policies related to air quality, use of sustainable energy sources, and other issues related to climate change. • Climate Action Plan—The City’s Climate Action Plan includes projects for reducing greenhouse gas emissions and adapting to likely impacts of climate change. These projects were reviewed to identify cross-planning initiates that serve both adaptation and mitigation objectives. • Community Wildfire Protection Plan—The Community Wildfire Protection Plan builds upon the October 2016 City of Santa Rosa Hazard Mitigation Plan providing more site-specific wildfire assessments and an action plan to address the wildfire threat to the City.

3.5.2 Opportunities for Future Integration
The capability assessment presented in this annex indicates opportunities to integrate this mitigation plan with other jurisdictional planning/regulatory capabilities. Capabilities were identified as integration opportunities if they can support or enhance the actions identified in this plan or be supported or enhanced by components of this plan. The capability assessment identified the following plans and programs that do not currently integrate hazard mitigation information but provide opportunities to do so in the future:
• Local Threat & Hazard Identification & Risk Assessment (THIRA) • Floodplain or Watershed Plan
• Post-Disaster Recovery Plan

3.6 RISK RANKING

3.6.1 Jurisdiction-Specific Natural Hazard Event History Table 3-11 lists past occurrences of natural hazards for which specific damage was recorded in Santa Rosa. Other hazard events that broadly affected the entire planning area, including Sonoma County, are listed in the risk assessments in Volume 1 of this hazard mitigation plan.

3.6.2 Hazard Risk Ranking
Table 3-12 presents a local ranking of all hazards of concern for which this hazard mitigation plan provides complete risk assessments. As described in detail in Volume 1, the ranking process involves an assessment of the likelihood of occurrence for each hazard, along with its potential impacts on people, property and the economy.

Mitigation actions target hazards with high and medium rankings. Note that the City of Santa Rosa has elevated Wildfire to a High ranking based on addition of the 2019 Kincade and 2020 Glass Fires to the Risk Assessment as well as information contained in the City’s Community Wildfire Protection Plan.

4.2 JURISDICTION PROFILE

4.2.1 Location and Features
The City of Sonoma is a historic city in northern California at the heart of the renowned Sonoma Valley winemaking region. The City is a small municipality, located in Sonoma County, 45 miles north of the San Francisco Golden Gate Bridge.

The current boundaries generally extend south to north from Leveroni Road/Napa Rd to Verano Avenue/Brazil Street and generally extend west to east from Sonoma Highway to Sixth Street East/Knight Street, encompassing an area of 2.72 square miles in size.

Sonoma has a typical lowland near-coastal Californian warm-summer Mediterranean climate (Köppen climate classification Csb) with hot, dry summers (although nights are comfortably cool) and cool, wet winters. In January, the normal high is 57.2°F and the typical low is 37.2°F.

Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 4-2

4.2.2 History
Sonoma was first incorporated as a city on April 4, 1850. When California achieved statehood on September 9, 1850, Sonoma County was one of the original counties. Sonoma's founder and leading citizen, General Vallejo, who had been elected as a state senator in the new state legislature, unsuccessfully lobbied to have Sonoma remain as the county seat of Sonoma County but it was moved to Santa Rosa in 1854 as the result of a disputed election. General Vallejo later had the city unincorporated on April 26, 1862, for the benefit of certain land owners such as himself. Then it was re-incorporated as a City on September 3, 1883, and the cornerstone of the Sonoma City Hall was laid on February 24, 1906.

Today, the citizens of Sonoma observe the founding of the Pueblo de Sonoma in 1835 on an annual Pueblo Day each June 24th. The Hispanic community of Sonoma Valley celebrates annually Cinco de Mayo on May 5th which is the date in 1862 that Mexico's army defeated French forces at the Battle of Puebla. The incursion of the Bear Flaggers in 1846 on June 14th is also observed annually with a re-enactment of the events of that day.

4.2.3 Governing Body Format
Sonoma operates under the Council/Manager form of government. The City Council is the elected body that oversees all municipal operations. The City Council provides policy leadership and acts as the legislative arm of City government. The five members of the City Council are elected to overlapping four-year terms, ensuring that there are Council Members with experience guiding the City at all times.

The City provides law enforcement services by contract with the Sonoma County Sherriff’s Office. Fire services are provided by contract with the Sonoma Valley Fire District. Schools are provided and operated by the Sonoma Valley Unified School District. Sewer service is provided by the Sonoma Valley County Sanitation District, managed and operated by Sonoma Water. Sonoma Valley Hospital services are provided through the Sonoma Valley Health Care District. The City of Sonoma operates its own water system, with the primary source of supply being provided by Sonoma Water (a County agency).

The Sonoma City Council assumes responsibility for the adoption of this plan and will oversee its implementation through its City Manager.

4.3 CURRENT TRENDS

4.3.1 Population
According to the State Department of Finance, Demographics Research Unit, the City of Sonoma had a population of 11,050 on January 1, 2020. This was a decrease of 1.0% from the year prior of 11,164.

4.3.2 Development
The City does not approve large subdivision tracts on a yearly basis or add large commercial projects. In fact, the City’s housing stock has only grown from 5,544 housing units in 2010 to 5,702 units in 2020 representing an increase in 158 housing units. Of these units, approximately 56% are single-family detached units. The City’s population per household is very low as compared to other jurisdictions in the State at 2.15 people per unit.

Since 2010, construction of new non-residential buildings within Sonoma has averaged 0.64 buildings per year.

Table 4-2 summarizes development trends in the performance period since the preparation of the previous hazard mitigation plan, as well as expected future development trends.

Table 4-2. Recent and Expected Future Development Trends Criterion Response
Has your jurisdiction annexed any land since
the preparation of the previous hazard
mitigation plan?
Yes
• If yes, give the estimated area annexed and
estimated number of parcels or structures.

The property is known as the “Montini Preserve” (approximately 60 acres) and is a hillside property dedicated as Open Space
Is your jurisdiction expected to annex any
areas during the performance period of this
plan?
No, however annexations of unincorporated islands within the City could occur. • If yes, describe land areas and dominant
uses.

• If yes, who currently has permitting
authority over these areas?

Are any areas targeted for development or
major redevelopment in the next five years?
Yes
• If yes, briefly describe, including whether
any of the areas are in known hazard risk
areas
Infill commercial, multi-family and single family that are not located within known hazard risk areas.

How many permits for new construction were
issued in your jurisdiction since the
preparation of the previous hazard mitigation
plan?
2015 2016 2017 2018 2019
Single Family 16 32 10 11 33
Multi-Family 0 8 5 24 24
Other (commercial, mixed use, etc.) 0 0 0 2 1
Total 16 40 15 37 58
Provide the number of new-construction
permits for each hazard area or provide a
qualitative description of where development
has occurred.
• Special Flood Hazard Areas: 1
• Landslide: 0
• High Liquefaction Areas: 0
• Tsunami Inundation Area: 0
• Wildfire Risk Areas: 2
Describe the level of buildout in the
jurisdiction, based on your jurisdiction’s
buildable lands inventory. If no such inventory
exists, provide a qualitative description.

The City has very few remaining parcels of vacant lands in which to develop. These lands are anticipated to develop with housing units for the most part consistent with the General Plan and Housing Element. Over the next 8 years, the City will need to provide zoning to accommodate approximately 330 new housing units

4.4 CAPABILITY ASSESSMENT
This section describes an assessment of existing capabilities for implementing hazard mitigation strategies. The introduction at the beginning of this volume of the hazard mitigation plan describes the components included in the capability assessment and their significance for hazard mitigation planning.

Findings of the capability assessment were reviewed to identify opportunities to expand, initiate or integrate capabilities to further hazard mitigation goals and objectives. Where such opportunities were identified and determined to be feasible, they are included in the action plan.

4.5 INTEGRATION REVIEW
For hazard mitigation planning, “integration” means that hazard mitigation information is used in other relevant planning mechanisms, such as general planning and capital facilities planning, and that relevant information from those sources is used in hazard mitigation. This section identifies where such integration is already in place, and where there are opportunities for further integration in the future. Resources listed at the end of this annex were used to provide information on integration. The progress reporting process described in Volume 1 of the hazard mitigation plan will document the progress of hazard mitigation actions related to integration and identify new opportunities for integration.

Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 4-10

4.5.1 Existing Integration
Some level of integration has already been established between local hazard mitigation planning and the following other local plans and programs:
• 2016 Urban Water Management Plan—This plan identifies measures to be implemented or projects to be undertaken to reduce water demands and address water supply shortfalls, and actions to be implemented in the event of a catastrophic interruption in water supplies. As required, the plan is being updated to include a drought risk assessment and a seismic risk assessment. The updated plan is scheduled for adoption before July 1, 2021. The 2020 Water Demand Analysis and Water Conservation Measure Update has been completed.
• 2018 Water Supply Strategies Action Plan (Sonoma Water)—Projects identified in the 2018 Water Supply Strategies Action Plan will help achieve supply reliability, well resilience, public safety, and cost- effective renewal and replacement of aging system components. • Southern Sonoma County Storm Water Resources Plan (2019)—This plan builds on local storm water management objectives and identifies and prioritizes projects that capture, treat or reuse storm water and dry weather runoff. These projects must provide at least two benefits which may include environmental enhancement, flood protection, groundwater recharge, water quality improvement and/or recreational opportunities. The plan provides a framework for submitting, quantifying, scoring, and ranking future projects in an objective and data driven format. Continued adaptation of the Storm Water Resources Plan will allow for productive stakeholder engagement and planning emphasizing a previously overlooked resource. This is an invaluable tool in the midst of changing climatic conditions that will continue to alter our local water supply resources and needs, contribute to water quality impairments, and exacerbate flood management challenges.
• 2008 Greenhouse Gas Emissions Reduction Action Plan—This plan was produced by a local non- profit with partial funding from the California Public Utilities Commission and direction by the city in response to the City Council’s adoption of a reduction target for internal operations of 20% below 2000 levels by 2010. It identified 15 actions (measures) to reduce greenhouse gas emissions primarily related to municipal operations. Between 2000 and 2018, GHG emissions from municipal operations decreased by

52.6%. In November 2020, a grant-funded consultant audited major city buildings to assess further GHG reductions through energy conservation, switching from natural gas to electricity, and to increase production via PV solar.
• 2020/21 Capital Improvement Program (CIP)—The CIP includes projects that can help mitigate potential hazards. These include projects identified in the 2018 Water Master Plan Update to achieve supply reliability, well resilience, public safety, and cost-effective renewal and replacement of aging system. Three creeks flow through the City: Nathanson Creek, Sonoma Creek, and Fryer Creek. Catch basins, roadside ditches, and storm drainage piping collect and convey storm water runoff to these creeks.

CIP projects can protect local creeks and the bay from pollutants associated with storm water runoff, and can provide flood prevention for the City's transportation network, residents, and businesses. The ongoing challenge for storm water projects is complying with the stringent and costly State and Federal mandates that are largely unfunded. The CIP proposes safety improvements, replacement of a degraded bridge, construction of a new pedestrian and bicycle bridge, parks/cemeteries/facilities upgrades and sidewalk repairs. The City will act to ensure consistency between the hazard mitigation plan and the current and future CIP. The hazard mitigation plan may identify new possible funding sources for CIP projects and may result in modifications to proposed projects based on results of the risk assessment. • Seismically Unsafe Building Regulations. The City’s regulations for the review, rehabilitation and abatement of existing seismically unsafe buildings (Sonoma Municipal Code Chapter 14.24) are

4. City of Sonoma
4-11
regulations designed to reduce the risk of death or injury resulting from earthquake hazards in existing masonry or concrete buildings in an economically feasible manner, while preserving the historic character of historic buildings.
• Flood Damage Prevention Regulations. The City’s Flood Damage Prevention Regulations (Sonoma Municipal Code Chapter 14.25) was updated in 2002. The provisions of the regulations are intended to minimize public and private losses due to flood conditions. • Building Code and Fire Code. The City’s adoption of the 2019 California Building Standards Code (Sonoma Municipal Code Chapter 14.10), incorporated local modifications to account for the climatic, topographic and geographic conditions that exist in the City as appropriate. • General Plan. This is a broad policy planning document guiding the City’s future development goals and provides policy statements to achieve those development goals. The City adopted the General Plan in 2006 and has updated the General Plan as recently as 2016 (in part) to guide the growth and land development of the community for both the current period and the long term. The General Plan is the foundation for establishing goals, purposes, zoning and activities allowed on each land parcel to provide compatibility and continuity to the entire region as well as each individual City neighborhood. • Sonoma Citizens Organized to Prepare for Emergencies—Training and organization of community members and groups designed to facilitate emergency preparation and response. • Staffing for Adequate Fire and Emergency Response Grants—Provides funding directly to fire departments and volunteer firefighter interest organizations to help them increase or maintain the number of trained, "front line" firefighters available in their communities. The goal of this grant program is to enhance the local fire departments' abilities to comply with staffing, response and operational standards established by the NFPA (NFPA 1710 and/or NFPA 1720).
• Community Risk Reduction Messaging Program—In collaboration with the Northern California Fire Prevention Officers Association and the National Fire Protection Agency our agency actively engages the community in Community Risk Reduction Messaging via in person training, social media outreach and engagement, website publications and through the press. • Creation of a newly formed fire district—The creation of the newly formed Fire District (Sonoma Valley Fire District) along with a contract for services with the City of Sonoma allows the fire department to take advantage of shared resources. These shared resources and realized cost savings allow the newly formed district to operate more effectively.

4.5.2 Opportunities for Future Integration
The capability assessment presented in this annex identified the following plans and programs that do not currently integrate hazard mitigation information but provide opportunities to do so in the future:
• Emergency Operations Plan—The City’s Emergency Operations Plan is in the process of being updated. The City will act to ensure consistency between the hazard mitigation plan and the emergency operations plan. Shortfalls identified in the EOP update may produce HMP action items to be addressed in future years.
• Capital Improvement Program—The updated HMP risk assessment may inform CIP projects to be addressed in future years.
• Urban Water Management Plan and Water Master Plan Update (2021)—The updated plans will include a drought risk assessment and a seismic risk assessment and may produce HMP actions to be addressed in future years.

Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 4-12
• Risk and Resilience Assessment and Emergency Response Plan (2021) required by America’s Water Infrastructure Act—Shortfalls identified in the assessment and plan may produce HMP actions to be addressed in future years.
• Climate Action Plan—The City’s Greenhouse Gas Emissions Reduction Action Plan (2008) is in need of updating into a Climate Action Plan (CAP). The City Council recently adopted a Climate Emergency Resolution and created a new joint standing Climate Action Subcommittee to address this issue. The HMP risk assessment and action items can help guide implementation goals of the CAP. • Sonoma Valley Fire Unmanned Aircraft Fire Prevention & Safety Unit—The Sonoma Valley Fire District has recently implemented a UAS (small unmanned aircraft system) program that may provide intelligence and information used to meet or identify future hazard mitigation goals.

4.6.2 Hazard Risk Ranking
Table 4-12 presents a local ranking of all hazards of concern for which this hazard mitigation plan provides complete risk assessments. As described in detail in Volume 1, the ranking process involves an assessment of the likelihood of occurrence for each hazard, along with its potential impacts on people, property, and the economy.

Mitigation actions target hazards with high and medium rankings.

4. City of Sonoma
4-13
NOTE: Landslide susceptibility was modified from Medium to Low risk (18 to 12) based on the landslide susceptibility map, probability, impact and the lack of recent observed or historical data to show that landslides will be a significant hazard within Sonoma city limits in other than very low populated areas. A landslide hazard event is not likely to occur within 100 years and 9 percent or less of the population is exposed to the hazard.

4.6.3 Jurisdiction-Specific Vulnerabilities
Volume 1 of this hazard mitigation plan provides complete risk assessments for each identified hazard of concern.

This section provides information on a few key vulnerabilities for the jurisdiction. Available jurisdiction-specific risk maps of the hazards are provided at the end of this annex.

Repetitive Loss Properties
Repetitive loss records are as follows:
• Number of FEMA-identified Repetitive-Loss Properties: Four (4) as of 3/28/2021 • Number of FEMA-identified Severe-Repetitive-Loss Properties: None as of 3/28/2021 • Number of Repetitive-Loss Properties or Severe-Repetitive-Loss Properties that have been mitigated:

None as of 3/28/2021
Other Noted Vulnerabilities
The following jurisdiction-specific issues have been identified based on a review of the results of the risk assessment, public involvement strategy, and other available resources:
• City administrative services may be impacted during power outages due to a lack of backup emergency generators for city administrative facilities.

Mitigation actions addressing these issues were prioritized for consideration in the action plan in this annex.

INFR – a-8: Pre-position emergency power generation capacity (or have rental/lease agreements for these generators) in critical buildings of cities, counties, and special districts to maintain continuity of government and services.

Yes
Comment: Emergency power generator in place for public safety & water system facilities. A permanent emergency generator is currently being installed at the Veterans Memorial Building (the City’s primary shelter location). No generators are currently installed for Schools or City Administrative offices but generators for the sites are available through rental/lease agreements on an as needed basis.

INFR – a-21: As an infrastructure operator, designate a back-up Emergency Operations Center with redundant communications systems.

Yes
Comment: Primary EOC is located at the City’s Police Station; The Backup EOC is located at Sonoma Valley Fire District Station #1.

Virtual EOC meeting capability has also been added as an EOC backup.

INFR – b-1: Expedite the funding and retrofit of seismically deficient city- and county-owned bridges and road structures by working with Caltrans and other appropriate governmental agencies.

No
Comment: The Chase Street bridge over Nathanson Creek has been identified as a structurally deficient bridge. The City’s request for funding to construct a replacement ridge has been approved but the funds have not yet been made available by Caltrans. The City is prepared to proceed with bridge construction as soon as Caltrans confirms that construction funds are available. No other bridges in Sonoma have been identified as structurally deficient at this time.

INFR – d-8: 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.

No
Comment: Part of the City's adopted storm water management plan. City hired an Environmental Compliance Analyst to enforce provisions. The City has not established a special statutory authority to keep watercourses free of obstructions in excess of nuisance abatement through civil action or through the acceptance of drainage easements. The City’s Stormwater Management Ordinance prohibits illicit discharges to the City’s storm drains, but does not create a positive duty upon private property owners to keep watercourses free of obstructions which are not released, added, or deposited by a person. Examples of obstructions of this type include obstructions formed by natural sediment aggradation, natural vegetative growth, accumulation of woody debris, or impoundments constructed by beavers.

INFR – d-17: Improve monitoring of creek and watercourse flows to predict potential for flooding downstream by working cooperatively with land owners and the cities and counties in the watershed.

Yes
Comment: Public Works Director sits on the Flood Control Zone 3A technical advisory committee. The City authorized Sonoma Water to install a rain gauge on the City’s Thornsberry water tank and a stream gauge at the Second Street East bridge over Nathanson Creek as part of the Sonoma One Rain network (https://sonoma.onerain.com/). The gauges improve monitoring and could be part of a system to predict potential for flooding downstream. The information provided by these gauges informs implementation of storm preparedness plans and public information and outreach.

INFR – d-18: Using criteria developed by EPA for asset management, inventory existing assets, the condition of those assets, and improvements needed to protect and maintain those assets. Capture this information in a Geographic Information System (GIS) and use it to select locations for creek monitoring gauges.

Yes
Comment: Sonoma Ecology Center and Sonoma County Water Agency provide information to County. As noted under d-17, a rain gauge and stream gauge have been installed. The City will continue to populate its asset inventory for storm drain infrastructure as capital improvements are constructed, or as-built surveys are performed. The City intends to continue to update its asset inventory and the information will likely be used to set inspection/maintenance schedules and potentially support updates and calibration of the hydraulic modeling detailed in the current Storm Drain Master Plan.

5.2 JURISDICTION PROFILE

5.2.1 Location and Features
Windsor is located approximately 58 miles north of San Francisco and 72 miles west of Sacramento, in Sonoma County, approximately five miles north of Santa Rosa and five miles south of Healdsburg. It is located on mostly flat land, bordered by hills to the north, east, and west. US Highway 101 runs through the middle of the Town along its north–south axis. Windsor is approximately 20 miles from the Pacific Ocean and two miles east of the Russian River, although a range of small hills divides the river from the Town itself.

The Town’s boundaries generally extend from Sotoyome Creek, Arata Lane, and Foothill Regional Park in the north, Windsor Road and Starr Road to the west, Shiloh Road to the South, encompassing an area of 7.4 square miles. An additional 0.1 square miles is located outside of Town limits and within the Town’s Urban Growth Boundary.

Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 5-2
climate of Windsor is semi-arid Mediterranean, characterized by dry, mild summers and moderately moist, cool winters. Over 90 percent of the rainfall occurs between October and May. Average summer temperatures are in the low 80s (degrees Fahrenheit) with highs in the upper 80s. Average temperatures in the winter are in the 50s.

Temperature variations between night and day tend to be relatively large during summer with a difference of up to 35 degrees and limited during winter with an average difference of 19 degrees. Precipitation generally occurs between October and May and the average rainfall is approximately 40 inches per year.

5.2.2 History
The area that is now Windsor was originally occupied by the Pomo people, who covered large sections of modern-day Sonoma, Mendocino, and Humboldt Counties. The Pomo hunted, fished, and foraged for a variety of food, including acorns, which were the primary plant staple. The Pomo lived in villages of grass-thatched homes during the winter and built temporary camps along streams in the summer. Prior to the arrival of Europeans in the area, the Pomo population is estimated at approximately 8,000.

The first known European expedition to the area occurred in 1810 by the Spanish army officer Gabriel Moraga. In 1812, Russia established Fort Ross as an outpost for fur hunting activities on the coast, approximately 24 miles from modern-day Windsor but ignored much of the interior. After the discovery of gold in 1848, California became part of the United States. Following the Mexican-American War, settlers began to arrive in the area in earnest. The first permanent settlers in modern-day Windsor came in 1851, when Henry Bell purchased 160 acres of land and founded a store that became the center of the new settlement. The first postmaster of the Town, Hiram Lewis, named the Town Windsor as it reminded him of the grounds around Windsor Castle in England. A rail line connected Windsor to San Francisco in 1872, spurring a rapid growth in agriculture. A U.S. Army air base (now Charles M. Schultz Sonoma County Airport) was established a short distance outside of the Town during World War II. New housing developments and the increasing popularity of Sonoma County’s wine industry brought growth to Windsor in the 1980s, leading to incorporation of the Town in July 1992.

5.2.3 The Governing Body Format
The Town of Windsor is governed by the Town Council, which is comprised of the mayor and four council members. Beginning with the November 3, 2020 election, Windsor began the transition to a district-based election system for Town council members and the mayor. The Town is divided into four council districts. The council member for each district is elected to serve a four-year term. The mayor is elected at large to serve a two- year term. The daily administration of the Town is overseen by the Town Manager, who is appointed by the Town Council.

The Windsor Town Council assumes responsibility for the adoption of this plan; the Town Manager will oversee its implementation.

5.3 CURRENT TRENDS

5.3.1 Population
According to the California Department of Finance, the population of Windsor as of January 2020 was 28,248.

Since 1995, the population has grown at an average annual rate of 1.9 percent.

5.3.2 Development
The primary land use in Windsor is single-family residential. Commercial uses include local-serving commercial uses located in the Town Green area and in small commercial centers. Regional-serving retail is located the southeast part of Windsor proximate to Highway 101. Larger single-family developments are planned for the northernmost part of Town, in the area north of Arata Lane that was annexed to the Town in 2018. Higher density multi-family development is located in the Station Area/Downtown Specific Plan area, which is close the SMART station which will open in 2021 and the bus depot. The Station Area/Downtown Specific Plan supports higher density mixed-use development in the downtown core. Additional mixed-use and higher density residential development is focused along Old Redwood Hwy and the eastern part of Shiloh Road, between Highway 101 and Old Redwood Hwy. Existing and new industrial development is located in the southwestern part of the Town, south of Shiloh Road and west of Highway 101 and in the Conde Lane/Mitchell Road/ Bell Road area.

Table 5-2 summarizes development trends in the performance period since the preparation of the previous hazard mitigation plan, as well as expected future development trends.

5.4 CAPABILITY ASSESSMENT
This section describes an assessment of existing capabilities for implementing hazard mitigation strategies. The introduction at the beginning of this volume of the hazard mitigation plan describes the components included in the capability assessment and their significance for hazard mitigation planning. This section summarizes the following findings of the assessment:
• An assessment of planning and regulatory capabilities is presented in Table 5-3. • Development and permitting capabilities are presented in Table 5-4. • An assessment of fiscal capabilities is presented in Table 5-5. • An assessment of administrative and technical capabilities is presented in Table 5-6. • An assessment of education and outreach capabilities is presented in Table 5-7. • Information on National Flood Insurance Program (NFIP) compliance is presented in Table 5-8. • Classifications under various community mitigation programs are presented in Table 5-9. • The community’s adaptive capacity for the impacts of climate change is presented in Table 5-10.

Findings of the capability assessment were reviewed to identify opportunities to expand, initiate or integrate capabilities to further hazard mitigation goals and objectives. Where such opportunities were identified and determined to be feasible, they are included in the action plan. The “Analysis of Mitigation Actions” table in this annex identifies these as community capacity building mitigation actions.

5.5 INTEGRATION REVIEW
For hazard mitigation planning, “integration” means that hazard mitigation information is used in other relevant planning mechanisms, such as general planning and capital facilities planning, and that relevant information from those sources is used in hazard mitigation. This section identifies where such integration is already in place, and where there are opportunities for further integration in the future. Resources listed at the end of this annex were used to provide information on integration. The progress reporting process described in Volume 1 of the hazard mitigation plan will document the progress of hazard mitigation actions related to integration and identify new opportunities for integration.

5.5.1 Existing Integration
Some level of integration has already been established between local hazard mitigation planning and the following other local plans and programs:
• 2040 Town of Windsor General Plan—The Windsor 2040 General Plan includes a Public Health and Safety Element that addresses hazards, as well as a GHG section and Climate Change and Resiliency section.
• 2019 Building Code—Windsor’s 2019 Building Code requires certain Fire (7A) building materials and methods for all new construction, including additions.
• Town of Windsor Capital Improvement Program—Four different Capital Improvement Programs (CIP) include hazard mitigation related projects: 1) Water (Potable) CIP, which includes projects for the treatment and delivery of water; 2) Water Reclamation CIP, which includes sewer, recycled water, and water treatment projects; 3) Drainage CIP, which includes projects for the conveyance and detention of Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 5-12
stormwater to prevent flooding; and 4) Traffic, which includes traffic and circulation improvements for pedestrians, bicycles, and vehicles, including sidewalks, trails, and roadways. • Water Master Plan –The latest plan was adopted in November 2019 • Riparian Corridor Wildfire Fuel Management Plan—The Plan was accepted by the Town Council in June 2020 and implements one of the actions listed in the Town’s local hazard mitigation plan.

5.5.2 Opportunities for Future Integration
The capability assessment presented in this annex identified the following plans and programs that do not currently integrate hazard mitigation information but provide opportunities to do so in the future:
• Zoning Ordinance—The Zoning Ordinance includes land uses and development standards for private property. The Town is in the process of preparing an update to the Zoning Ordinance. The intent is to include requirements related to reducing the spread of wildfire due to ember-cast by including landscaping, fencing, and porch/deck requirements.
• Regional Water Resiliency Plan—The Regional Water Resiliency Plan is expected to be completed in Spring 2022.
• Water Risk and Resiliency Assessment (As Required by The American Water Infrastructure Act/Plan)—The Water Risk and Resiliency Assessment is due June 30, 2021 (1st submittal due) and December 31, 2021 (2nd submittal due).
• Windsor Climate Adaptation Plan—The Windsor Climate Adaptation Plan (Windsor Ready) is currently being prepared and will include measures that Windsor can take to adapt to climate change and will assist in the implementation of the Hazard Mitigation Plan. The Plan is expected to be completed in January 2022.
• Water Shortage Contingency Plan Update –The Water Shortage contingency Plan Update is due June 30, 2021.
• Drought Contingency Ordinance Update –The Drought Contingency Ordinance update will begin after adoption of the Water Shortage Contingency Plan Update.

Table 5-12 presents a local ranking of all hazards of concern for which this hazard mitigation plan provides complete risk assessments. As described in detail in Volume 1, the ranking process involves an assessment of the likelihood of occurrence for each hazard, along with its potential impacts on people, property and the economy.

Mitigation actions target hazards with high and medium rankings.

Table 5-12. Hazard Risk Ranking
Rank Hazard Type Risk Rating Score (Probability x Impact) Category 1 Dam Failure 36 High
1 Earthquake 36 High
2 Wildfirea 35 High
3 Severe Weather 30 Medium
4 Flood 18 Medium
5 Droughta 18 Medium
6 Landslide 18 Low
7 Sea Level Rise 0 None
8 Tsunami 0 None
a. Quantitative rankings have been qualitatively adjusted based on local experience and knowledge.

Windsor’s Hazard Mitigation Planning Team modified the following rankings: Wildfire changed from “Medium” to “High”; Landslide changed from “Medium” to “Low,”; and Drought changed from “Low” to “Medium.”” The basis for the changing in the ranking of these hazards if provided below. • Wildfire. The ranking for Wildfire was changed from medium to high based on: (1) the Kincade Fire in October 2019 resulted in the evacuation of all of Windsor and was expected to engulf the entire Town.

The Town was spared due to a change in wind direction and the preparation, staging, and actions of firefighters; (2) the Walbridge Fire, which started on August 17, 2020, resulted the northwestern area of Windsor being under an evacuation warning; and (3) based on the risk assessment prepared for the Climate Adaptation Plan, there are two types of wildfire risk facing the Town, traditional wildfire risk Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 5-14
focused on buildings and people in the WUI, which creates a gradient of risk from the edges of Town and the emerging firestorm storm risk fueled by climate change that creates ember-cast that spreads wildfire to areas that not adjacent to the WUI. The map prepared for the Climate Adaptation Plan supports a risk ranking of High and is included as an attachment to this Annex. • Landslide. The ranking for Landslide was changed to low from medium based on: (1) Windsor’s topography being generally flat, with slopes limited to the northeastern hills which is less densely developed; (2) this hazard is less likely to occur than most of the other hazards; and (3) the extent and severity of the risk is more limited than the other hazards facing the Town. • Drought. The ranking for Drought was changed from Low to Medium is based on: (1) the Town is currently experiencing a drought; (2) the Town experienced a prolonged drought from 2012 to 2017; (2) the likelihood of droughts becoming more frequent, longer in duration, and more severe; and (3) the potential impact on people and businesses depending on the measures enacted at the State and local level to ensure adequate water quantity and quality.

5.6.3 Jurisdiction-Specific Vulnerabilities
Volume 1 of this hazard mitigation plan provides complete risk assessments for each identified hazard of concern.

This section provides information on a few key vulnerabilities for the jurisdiction. Available jurisdiction-specific risk maps of the hazards are provided at the end of this annex.

Windsor’s Hazard Mitigation Planning Team identified the following jurisdiction-specific vulnerabilities: (1) localized flooding; (2) spread of wildfire along riparian corridors; (3), narrow bridges that could impede emergency access and evacuation during hazard events; and (4) neighborhoods with one point of access. Each of these vulnerabilities is described in greater detail below. • Localized Flooding: During rain and storm events, localized flooding occurs in several areas throughout Windsor, including Pool Creek at Windsor Road, Dawn Way near the intersection with Old Redwood Hwy, and the intersections of Arata Lane/Highway 101, Shiloh Road/Caletti Avenue, and Shiloh Road/Hwy 101 southbound on-ramp.
• Wildfire Spread Along Riparian Corridors: Based on experience with recent fires in our area, riparian corridors have been identified as areas that can provide a pathway for the spread of wildfire through Windsor, especially if regular fuel management is not occurring in these areas. Windsor is in the process of developing a climate adaptation plan (Windsor Ready Plan), which identifies creek corridors as areas that could result in the spread of wildfire throughout the Windsor. Most of the creeks in Windsor are bordered by residential development on both sides, placing people and homes at risk. The Town and Sonoma County Fire District have prepared the Riparian Corridor Wildfire Management Plan and is currently seeking funding to implement the plan.
• Narrow Bridges: Narrow two-lane bridges are located in several areas in Windsor, including Caletti Lane, Hembree Lane, Conde Lane, and Old Redwood Hwy between Billington Lane and Deanna Place.

The bridge on Caletti Avenue is a wooden bridge that serves as the access point for the Town’s industrial area. Hembree Lane and Old Redwood Hwy are primary crosstown streets that provide access to Hwy 101. Impeded access in these areas would limit emergency access and evacuation. Conde Lane is also a crosstown street that provides access to Hwy 101 via Shiloh Road. • Single-Point of Access Areas: A climate adaptation plan is currently being developed for the Town, which has identified neighborhoods with a single-point of access. Much of Windsor was developed when it was standard practice to develop neighborhoods with a curvilinear street design with cul-de-sacs, rather than on a grid system that provides multiple points of access and better connectivity. For some areas, due

5. Town of Windsor
5-15
to the number of homes and served by the single-point of access, this could impede emergency access to these locations and evacuation if the access is blocked.

Repetitive Loss Properties
Repetitive loss records are as follows:
• Number of FEMA-identified Repetitive-Loss Properties: None as of 3/28/2021 • Number of FEMA-identified Severe-Repetitive-Loss Properties: None as of 3/28/2021 • Number of Repetitive-Loss Properties or Severe-Repetitive-Loss Properties that have been mitigated:

None as of 3/28/2021
Other Noted Vulnerabilities
No other jurisdiction-specific issues have been identified based on a review of the results of the risk assessment, public involvement strategy, and other available resources.

Drought 3.3
Expand use of xeriscaping or drought-tolerant native plants in Town-maintained landscaped areas to the extent possible. (Continue Current Practice) 
Comment: This is the Town’s practice and is implemented through the Parks and Recreation Department. It does not need to be included as a mitigation action, since it is already Town practice and the Town wants to focus on other actions.

Drought 3.4
Encourage all new landscaping projects to exceed minimum state water efficiency requirements.

Comment: The Town’s Water Efficiency Ordinance requires compliance with State requirements. The Town wants to focus on other actions that would better address drought.

Drought 3.5
Incorporate drought frequency (i.e., multiple-dry year hydrologic conditions) into Town’s urban water management planning efforts.

Comment: The Town’s Urban Water Management Plan (UWMP) is required to include this information. The Town is updating its UWMP at this time and the update includes this information as required.

Drought 3.6
Offer incentives for water efficiency retrofits to existing homes and businesses, and explore ways to expand incentive opportunities.

Earthquake 4.2
Develop incentives or requirements for property owners to retrofit seismically vulnerable structures.

Comment: Most buildings in Windsor were built in the mid-1980s or later, so the buildings are consistent with modern seismic requirements. The Building Code requires water heaters to be strapped down to address seismic hazards. Since water heaters last approximately 10 years, it is likely that water heaters in Windsor are consistent with this requirement. Due to the above, retrofits would likely be cost prohibitive.

Earthquake 4.3
Identify incentives to encourage residential project applicants to build new residential structures so they remain safely habitable following a substantial earthquake. 
Comment: Since the Town is in an area of seismic activity, the Building Code requires buildings to be constructed to meet specific seismic requirements.

Extreme Heat 5.1
Designate community facilities to operate as cooling centers when temperatures reach an established threshold, and ensure designated facilities are adequately stocked with necessary supplies. Widely distribute information about cooling centers to Windsor residents. Ensure that there is sufficient staffing and other resources to allow cooling centers to operate on all days, including weekends and holidays if needed. (Continue Current Practice and Preparedness Related Activity)

Comment: This item has been moved to the EOC team for ongoing implementation.

Extreme Heat 5.2
Encourage property owners to weatherize homes and businesses in Windsor, particularly older structures, including the planting of shade trees. 
Comment: Since this action does not include a project or program, the Town has decided it would like to focus on other actions.

Extreme Heat 5.3
Educate Town employees, particularly employees who frequently work outdoors, about extreme heat hazards. Encourage other employers in Windsor to provide extreme heat training to their employees. (Preparedness Related)

Comment: This is done by the Human Resources, which also provides alerts Town employees on extreme heat/weather days and days with unhealthy air quality.

Extreme Heat 5.4
Provide shade structures at bus stops, and in public parks and other landscaped areas.  WIN-29
Comment: The Parks and Recreation Department plants trees in public parks that provide shade. This action has been revised as action WIN-29 in Table 1.14 below.

Flooding 6.2
Conduct storm drain maintenance regularly to ensure systems are operating at peak capacity, especially in advance of and during the rainy season. (Preparedness Related)  WIN-25
Comment: This is ongoing standard practice for the Public Works Department before and during rain events. Included as Action WIN-25 in Table 1.14 below.

Flooding 6.3
Retrofit public surfaces and landscapes, including plazas, parking lots, and parks, to use low-impact development strategies such as permeable paving, rain gardens, and bioswales. (Continue Current Practice)

Comment: This action, since it implements low impact development (LID), has a nominal effect on flooding or severe weather events.

The use of LID is also a Town requirement and standard practice. Other actions have been included that better mitigate flooding and severe weather events.

Flooding 6.4
Restrict land uses in floodways to uses that are compatible with occasional flooding, including agricultural operations, open space, and natural conservation land. Discourage new development within the 100-year floodplain. (Continue Current Practice) 
Comment: The Town’s Floodplain Management Ordinance restricts development in the floodway and discourages development in the 100-year floodplain by requiring development to be elevated above the base flood level and allowing “no net runoff” from the site.

Flooding 6.5
Explore requiring all new development in the 100-year and 500-year floodplains to implement flood mitigation strategies, emphasizing the use of low-impact development and “soft” strategies.

Comment: This action has been determined to be infeasible. There are few areas in Windsor that are in the 500-year floodplain and they have already been developed.

Flooding 6.6
Require that new development projects, including infrastructure, will not change local hydrology and cause an increase in flood risks for surrounding properties.  WIN-26
Comment: This is required by the Town’s Municipal Code and Building Code. Continue current practice. Included as Action WIN-26 in Table 1.14 below.

Flooding 6.7
Develop passive detention basins to better collect and manage stormwater flows, designing and building the basins to be consistent with low-impact development strategies.  WIN-27
Comment: Low impact development and detention are different types of actions and should not have been included in the same action.

Revised this action to delete the reference to low impact development. See Action WIN-27 in Table 1.14 below.

6.4 CAPABILITY ASSESSMENT
This section describes an assessment of existing capabilities for implementing hazard mitigation strategies. The introduction at the beginning of this volume of the hazard mitigation plan describes the components included in the capability assessment and their significance for hazard mitigation planning.

Findings of the capability assessment were reviewed to identify opportunities to expand, initiate or integrate capabilities to further hazard mitigation goals and objectives. Where such opportunities were identified and determined to be feasible, they are included in the action plan. The “Analysis of Mitigation Actions” table in this annex identifies these as community capacity building mitigation actions. The findings of the assessment are presented as follows:
• An assessment of planning and regulatory capabilities is presented in Table 6-3. • An assessment of fiscal capabilities is presented in Table 6-4. • An assessment of administrative and technical capabilities is presented in Table 6-5. • An assessment of education and outreach capabilities is presented in Table 6-6. • Classifications under various community mitigation programs are presented in Table 6-7. • The community’s adaptive capacity for the impacts of climate change is presented in Table 6-8.

6.5 INTEGRATION REVIEW
For hazard mitigation planning, “integration” means that hazard mitigation information is used in other relevant planning mechanisms, such as capital facilities planning, and that relevant information from those sources is used in hazard mitigation. This section identifies where such integration is already in place, and where there are opportunities for further integration in the future. Resources listed at the end of this annex were used to provide information on integration. The progress reporting process described in Volume 1 of the hazard mitigation plan will document the progress of hazard mitigation actions related to integration and identify new opportunities for integration.

6.5.1 Existing Integration
Some level of integration has already been established between local hazard mitigation planning and the following other local plans and programs:
• Integration will occur with local CWPP plans in the development process once completed. • Implementation of Advanced Life Support Services—Cloverdale Health Care Ambulance District. provides ALS personnel and fire district help staff ambulances EMT positions. • Disaster Operations Policies and Procedures—Cloverdale Fire District, has standing policies and procedures dictating emergency operations preparing for, during, and after natural disasters. These policies include not only emergency operations but also assessment of District owned capital assets after such events.
• Department Social Media—Posts continuous message throughout the Fire District to educate and inform our populace on a wide variety of topics that include fire safety and disaster preparation. • Continuance of Community Risk Reduction Program—Cloverdale Fire District, maintains a prevention/community risk reduction program ranging from building inspections, construction plan review, community education.
• Continue to participate in general mutual aid agreements with adjoining jurisdictions and statewide—Cloverdale Fire District, participates in various mutual and automatic aid agreements with neighboring fire districts as well as is an active participant in the statewide mutual system, especially during wildfire season.
• North County Citizens Organized to Prepare for Emergencies (COPE)—Training and organization of community members and groups designed to facilitate emergency preparation and response. • North County Citizens Emergency Response Team (CERT) Training and organization of specifically trained community members to facilitate emergency preparation and response. • Staffing for Adequate Fire and Emergency Response Grants—Provide funding directly to fire departments and volunteer firefighter interest organizations to help them increase or maintain the number of trained, "front line" firefighters available in their communities. The goal of this grant program is to enhance the local fire departments' abilities to comply with staffing, response and operational standards established by the NFPA (NFPA 1710 and/or NFPA 1720).
• Community Risk Reduction Messaging Program—In collaboration with the Northern California Fire Prevention Officers Association and the National Fire Protection Agency our agency actively engages the community in Community Risk Reduction Messaging via in person training, social media outreach and engagement, website publications

6. Cloverdale Fire Protection District
6-7
• Hazardous Vegetation Inspection & Abatement Program—In cooperation with the Sonoma County PRMD Fire Prevention Office the Cloverdale Fire District inspects properties for compliance. Selected properties that are not within city limits (improved and unimproved) may be part of the inspection program. Critical to protect homes from wildfire, defensible space includes a "lean, clean and green" zone 30 feet (or to the property line) from buildings, and a "reduced fuels zone," which can have more natural vegetation, from 30 feet to 100 feet (or to the property line) from structures. • Creation of a newly formed Joint Powers Agreement—The creation of the newly formed North County Fire is a partnership with former Geyserville Fire District, Now North County Fire Protection District to provide coordinated services throughout the north county. This allows the fire department to standardize and provide shared resources.

Opportunities for Future Integration
The capability assessment presented in this annex identified the following plans and programs that do not currently integrate hazard mitigation information but provide opportunities to do so in the future:
• Continue to pursue grant funding opportunities for updating facilities and equipment • Help form, train, and participate in a county-wide incident management team, overhead incident requests. • Help further develop, train, and build relationships with both county and city EOCs. • Conduct on going risk assessments for the Cloverdale Fire District and the ability to focus on key risk factors identified therein.
• Collaborate with area fire agencies on preparedness, response, planning, recovery, and mitigation plans, strategies, and protocols.
• Integrate the Sonoma County Wildfire Mitigation Plan with this plan • Integrate any city or specific community CWPP plan with the plan.

6.6 RISK ASSESSMENT

6.6.1 Jurisdiction-Specific Natural Hazard Event History Table 6-9 lists past occurrences of natural hazards for which specific damage was recorded in the north county.

Other hazard events that broadly affected the entire planning area, including jurisdictions in Sonoma County are listed in the risk assessments in Volume 1 of this hazard mitigation plan.

6.6.2 Hazard Risk Ranking
Table 6-10 presents a local ranking of all hazards of concern for which this hazard mitigation plan provides complete risk assessments. As described in detail in Volume 1, the ranking process involves an assessment of the likelihood of occurrence for each hazard, along with its potential impacts on people, property and the economy.

Mitigation actions target hazards with high and medium rankings.

7.2 JURISDICTION PROFILE

7.2.1 Overview
The North Sonoma Coast Fire Protection District (NSCFPD) was formed on April 1, 2016. Previously, fire protection in the Sea Ranch / Annapolis / Stewart’s Point area was provided by the Sea Ranch Volunteer Fire Department, the Annapolis Volunteer Fire Department, and CAL FIRE. All funds supporting these operations were from property taxes, which were transferred to Sonoma County Service Area #40 (CSA40). CSA40 in turn contracted with The Sea Ranch Volunteer Fire Department, the Annapolis Volunteer Fire Department, and CAL FIRE to provide fire protection. The new district covers the areas previously served by The Sea Ranch and Annapolis Volunteer Fire Companies, with the continued support of CAL FIRE.

The highest density of population and structures within the district falls within the boundaries of The Sea Ranch Association (TSRA). TSRA and associated TSR Water Company provide facilities that are essential to the operations of NSCFPD. These include water service and hydrants throughout The Sea Ranch (TSR) as well as broadband communications for district facilities located in TSR.

Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 7-2
TSRA provides various support for the Fire District including but not limited to administrative services, maintenance, and emergency management services.

The climate in the Fire District ranges from 4 1°F to 80 °F to 100 °F inland—east of Annapolis. is 41 – 80 degrees at the coast to 100 degrees to the east in Annapolis.

7.3 CURRENT TRENDS
According to the 2010 Census, as noted in Wikipedia, the population of the Fire District was reported as 1,305 and for The Sea Ranch and Annapolis as 401. Records from our Design department reflect that there are currently 1,776 single-family homes with an additional 45 units under the Burbank (HUD). The population varies seasonally seeing more people relocating here full time as opposed to vacationing here from all over the country and Europe.

Trends in construction are generally low for the Sea Ranch area until this year where we have seen an uptick of building with 20 open builds in progress or newly completed. Less than 10 of newly developed properties in the Annapolis area and no significant development planned anywhere in the District. Table 7-3 summarizes development trends in the performance period since the preparation of the previous hazard mitigation plan, as well as expected future development trends.

7.5 INTEGRATION REVIEW
For hazard mitigation planning, “integration” means that hazard mitigation information is used in other relevant planning mechanisms, such as capital facilities planning, and that relevant information from those sources is used in hazard mitigation. This section identifies where such integration is already in place, and where there are opportunities for further integration in the future. Resources listed at the end of this annex were used to provide information on integration. The progress reporting process described in Volume 1 of the hazard mitigation plan will document the progress of hazard mitigation actions related to integration and identify new opportunities for integration.

7.5.1 Existing Integration
Some level of integration has already been established between local hazard mitigation planning and the following other local plans and programs:
• North Sonoma Coast Volunteer Firefighter Association—Support organization for district, raises funds for district’s expenditures on apparatus, equipment, and PPE, publishes district newsletter, sponsors community events.
• Horicon School—emergency evac zone for Annapolis area. Air medical evac landing zone. Venue for ongoing public education by the district for fire and hazard mitigation. • Coast Life Support District—Local ALS ambulance service. Provides EMS education and training.

Several district personnel are also part-time EMS providers with this EMS agency. • CalFire—Schedule A fire captain performs fire safety inspections and participates in community events to provide fire safety education
• General Mutual Aid—with adjoining jurisdictions, assistance given with IT and radio programming tasks
• Sea Ranch Community Wildfire Protection Plan—North Sonoma Coast Fire Protection District participated in the creation of the Sea Ranch CWPP.

7.5.2 Opportunities for Future Integration
The capability assessment presented in this annex identified the following plans and programs that do not currently integrate hazard mitigation information but provide opportunities to do so in the future:
• NSCVFA—Continue close cooperation for the use of the North Fire Station facilities and to raise funds for equipment and maintenance
• Creation of a district-wide CWPP—Current Community Wildfire Protection Plan covers TSR only. An opportunity exists to create a CWPP for the entire district, including Annapolis • County and state organizations—Continue working with county emergency organizations and Fire Safe Council, as well as CalFire.

8.2 JURISDICTION PROFILE

8.2.1 Overview
The Northern Sonoma County Fire Protection District was formed in 2020 after the Geyserville Fire Protection District annexed the Knights Valley Volunteer Fire Company service area. The Geyserville Fire Protection District was formed in 1996 and was previously the Geyserville Volunteer Fire Company which dates back to 1910 which serves the community of Geyserville and surrounding area.

The Northern Sonoma County Fire Protection District is located in a Mediterranean climate with a rainy, cool season lasting from November through April and dry, warm conditions the remainder of the year. The District receives less amount of coastal influence (cool weather and occasional fog) than other portions of the county in elevations less than 1,000 feet. The average monthly high temperature is between 90 and 58 degrees with the average monthly low temperature between 52 and 36 degrees. Rainfall averages between 25 and 30 inches.

Flooding and fire are becoming more common.

Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 8-2
The Northern Sonoma County Fire Protection District is an independent special district with a five member Board of Directors. The Board position include a president, vice president, and treasurer.

The Northern Sonoma County Fire Protection District Board of Directors assumes responsibility for the adoption of this plan; The Fire Chief will oversee its implementation.

8.2.2 Service Area
The Northern Sonoma County Fire Protection District is a rural jurisdiction located between Healdsburg and Cloverdale in northern Sonoma County encompassing 273 square miles. In the east the District stretches from Mt.

St. Helena where the Sonoma County line meets the Lake and Napa County Lines to West of Lake Sonoma where it meets the Mendocino County Line. The District encompasses the Dry Creek Valley, Alexander Valley, Knights Valley, and Franz Valley. The District provides services to Lake Sonoma, which provides water to 600,000 residents in Sonoma and Marin County, and covers a majority of the upper portion of the Russian River that is located in Sonoma County.

8.3 CURRENT TRENDS
Population has remained consistently due to lack of significant increase in housing. Population is estimated around 6,000 residents. The population can fluctuate due to recreation, tourism, seasonal agriculture, and occupancy of vacation rentals and second homes.

The Northern Sonoma County Fire Protection District encompasses a large area of rural undeveloped lands.

Residential, commercial, mixed use and agriculture land exist throughout the District with most structures being along US Highway 101, CA Highway 128, and in the Dry Creek Valley. Development in Geyserville is limited by water and sewer connections.

8.5 INTEGRATION REVIEW
For hazard mitigation planning, “integration” means that hazard mitigation information is used in other relevant planning mechanisms, such as capital facilities planning, and that relevant information from those sources is used in hazard mitigation. This section identifies where such integration is already in place, and where there are opportunities for further integration in the future. Resources listed at the end of this annex were used to provide information on integration. The progress reporting process described in Volume 1 of the hazard mitigation plan will document the progress of hazard mitigation actions related to integration and identify new opportunities for integration.

8.5.1 Existing Integration
Some level of integration has already been established between local hazard mitigation planning and the following other local plans and programs:
• Wildland Vegetation Management Program including a “fuels crew” which is performing vegetation management and modification to reduce the intensity of future fires. • Implementation of prescribed burning with a focus on burning near structures. • Defensible Space Inspections and Assessments to increase awareness, educate, and abate regarding vegetation management around structures and along roads. • Wildland pre-attack maps to assist with effective evacuations, structure defense, and wildfire perimeter control.
• Community meetings and educational videos to increase awareness for prevention and preparedness.

8.5.2 Opportunities for Future Integration
The capability assessment presented in this annex identified the following plans and programs that do not currently integrate hazard mitigation information but provide opportunities to do so in the future:
• Building life safety inspections to reduce structure fires and prevent the loss of life. • Increase coordination with US Army Corps for potential dam failure and associated response plan for the Warm Springs Dam.
• Expand the Lower Russian River Flood plan to the remaining portions of the Russian River in Sonoma County.
• Develop and implement FIREWISE USA (and/or CWPP) projects including vegetation management fuel reduction projects.
• Fire impact fees

10.2 JURISDICTION PROFILE

10.2.1 Overview
The Sonoma Valley Fire District (SVFD) is a newly formed special district created when the Valley of the Moon Fire District, Glen Ellen Fire Protection District and the Mayacamas Volunteer Fire Company joined as one to create the new district effective July 1, 2020. This new district also provides fire and emergency medical services under contract to the incorporated City of Sonoma.

The climate of the Sonoma Valley Fire District is heavily influenced by its close proximity to nearly 60 miles of Pacific Coast shoreline, and its cool nights and temperate days create the perfect conditions to draw in layers of oceanic fog to chill Sonoma’s warm interior valleys. Daytime temperatures average a comfortable 71˚F, with the warmest summer days rarely topping 84˚F. Nighttime temperatures stay mostly in the 40s, meaning hard frosts are a rarity, even during critical flowering time for grapes. At the start of fall harvest, the weather remains moderate with little to no rainfall. Sonoma County experiences no measurable snow or hail and normal rainfall measures between 25 and 30 inches a year.

The Sonoma Valley Fire District Board of Directors made up of seven elected board members, a president, vice president, treasurer and four directors.

The Sonoma Valley Fire District Board of Directors assumes responsibility for the adoption of this plan; the Sonoma Valley Fire District will oversee its implementation.

Sonoma County Multijurisdictional Hazard Mitigation Plan Update 2021; Volume 2—Planning Partner Annexes 10-2

10.2.2 Service Area
The Sonoma Valley Fire District is located within the Sonoma Valley.

The current boundaries generally extend from Leveroni Rd to the North to the southern border of Kenwood Community between the Sonoma mountain range to the Mayacamas mountain range. The Sonoma Valley Fire District encompasses a large area of lands including residential, commercial, mixed use and agriculture land in unincorporated Sonoma County lands. We also provide service to the incorporated City of Sonoma.

According to the 2019 Sonoma County Economic Development Board City Profile And Projections Report, the population of the City of Sonoma as of December of 2019 is estimated to be 11,253, an average annual population growth rate of 0.65% percent. While we are unable to find Census tract data to determine exact populations for the Sonoma Valley Fire District, we estimate that in addition to the City’s population, we serve an additional 37,000 residents within the Fire District.

10.3 CURRENT TRENDS
Development in all zoning areas occurs at a moderate level. The Springs redevelopment project is changing some local zoning regulations and is bringing in new opportunities.

10.4 CAPABILITY ASSESSMENT
This section describes an assessment of existing capabilities for implementing hazard mitigation strategies. The introduction at the beginning of this volume of the hazard mitigation plan describes the components included in the capability assessment and their significance for hazard mitigation planning.

Findings of the capability assessment were reviewed to identify opportunities to expand, initiate or integrate capabilities to further hazard mitigation goals and objectives. Where such opportunities were identified and determined to be feasible, they are included in the action plan. The “Analysis of Mitigation Actions” table in this annex identifies these as community capacity building mitigation actions. The findings of the assessment are presented as follows:
• An assessment of planning and regulatory capabilities is presented in Table 10-3. • An assessment of fiscal capabilities is presented in Table 10-4. • An assessment of administrative and technical capabilities is presented in Table 10-5. • An assessment of education and outreach capabilities is presented in Table 10-6. • Classifications under various community mitigation programs are presented in Table 10-7. • The community’s adaptive capacity for the impacts of climate change is presented in Table 10-8.
