Population and Property—Population and property exposure and vulnerability would be unlikely to increase as a direct result of climate change impacts on the severe storm hazard.
Severe winter storms and thunderstorms may occur more frequently, but exposure and vulnerability will remain the same. Secondary impacts, such as the extent of localized flooding, may increase, impacting greater numbers of people and structures.
Critical facilities—Critical facility exposure and vulnerability would be unlikely to increase as a result of climate change impacts on the severe storm hazard; however, critical facility owners and operators may experience more frequent disruption to service provision. For example, more frequent and intense storms may cause more frequent disruptions in power service.
Environment—Exposure and vulnerability of the environment would be unlikely to increase; however, more frequent storms and more intense rainfall may place additional stress on already stressed systems.
18.2.8 Severe Weather
According to the Fourth National Climate Change Assessment, over the past two decades, the number of high temperature records in the United States far exceed the number of low temperature records (U.S. Global Change Research Program 2018). The increase in average surface temperatures can lead to more intense heat waves. Evidence suggests that heat waves are already increasing, especially in western states.
Climate change impacts on winds are still not well understood. Until recently, scientists had predicted rapid inland warming would weaken one of the primary drivers for Santa Ana winds and reduce their frequency. But a 2021 study found that bouts of hot Santa Ana winds are not declining and could even be increasing (Science 2021).
The following summarizes changes in exposure and vulnerability to the severe weather hazard resulting from climate change:
Population and Property—Population and property exposure and vulnerability would be unlikely to increase as a direct result of climate change impacts on the severe weather hazard.
Severe weather events may occur more frequently, but exposure and vulnerability will remain the same.
Critical facilities—Critical facility exposure and vulnerability would be unlikely to increase as a result of climate change impacts on the severe weather hazard; however, critical facility owners and operators may experience more frequent disruption to service provision. For example, more frequent and intense windstorms may cause more frequent disruptions in power service.
Environment—Exposure and vulnerability of the environment would be unlikely to increase; however, more frequent wind and heat events may place additional stress on already stressed systems.

18.2.9 Tsunami
The impacts of global climate change on tsunami probability are unknown. However, even if climate change does not increase the frequency with which tsunamis occur, it may result in more destructive waves. As sea levels continue to rise, tsunami inundation areas would likely extend further inland.
The following summarizes changes in exposure and vulnerability to the tsunami hazard resulting from climate change:
Population, Property, and Critical Facility—Population, property, and critical facility exposure and vulnerability to the tsunami hazard may increase as a result of climate change-related sea- level rise. As sea levels rise, tsunami impact areas may reach into parts of the community that were previously outside the tsunami risk area. The extent of this change will depend on the size of the tsunami, the local topography, and the extent of sea-level rise in the area.
Environment—Exposure and vulnerability of the environment to tsunamis may be impacted by the effects of climate change. In particular, sea-level rise could alter the shape of the existing shoreline, placing different structures and ecosystems at risk from potential tsunami impacts.
Additionally, ice crust melt could lead to a rise of the earth’s crust, especially at higher latitudes, causing more submarine landslides and a greater vulnerability to tsunamis.
18.2.10 Wildfire
Climate change has the potential to affect multiple elements of the wildfire system: fire behavior, ignitions, fire management, and vegetation fuels. Hot dry spells create the highest fire risk. Increased temperatures may intensify wildfire danger by warming and drying out vegetation.
Climate change may increase winds or change the timing/seasonality of winds that spread fires. Most of California’s worst wildfires occur in the fall, when vegetation is driest and the Santa Ana winds start to pick up. Some research indicates a shift in the annual pattern of Santa Ana winds that would move the wildfire season later in the year (AGU 2019).
Changes in climate patterns may impact the distribution and perseverance of insect outbreaks that create dead trees (increase fuel). When climate alters fuel loads and fuel moisture, forest susceptibility to wildfires changes.
The following summarizes changes in exposure and vulnerability to the wildfire hazard resulting from climate change:
Population, Property and Critical facilities—According to Projected Changes in Ventura County Climate, wildfire risk in Ventura County is expected to increase, with wildfire season starting earlier and extending later in the year due to drought, increased temperatures, and greater evaporative demand. While the future frequency, size and intensity of wildfires is uncertain, it is likely that exposure and vulnerability to the wildfire hazard would increase.
Environment—It is likely that the exposure and vulnerability of the environment will be impacted by changes in wildfire risk due to climate change. Natural fire regimes may change, resulting in more frequent or higher intensity burns. These impacts may alter the composition of the ecosystems in areas in and surrounding planning area. Whether areas burn more frequently, or more acreage is burned in each fire, wildlife has the potential to become more stressed as suitable habitat is lost.

18.2.11 Other Hazards of Interest
Agricultural and Biological Hazards
The impacts of global climate change on agricultural and biological hazards are still being studied, however climate change is known to be influencing the spread of many invasive species. Increased temperatures, and both intense rainfall and drought can facilitate the spread and establishment of non- native species, creating new opportunities for them to become invasive (U.S. Department of Agriculture 2021b). Prolonged drought stresses trees and can result in higher susceptibility to detrimental pests.
Pandemic
Climate change will likely have significant indirect impacts on disease outbreaks. In California, injuries and premature deaths related to extreme weather events, changes in the prevalence and geographical distribution of food- and water-borne illnesses and other infectious diseases should be anticipated. The fourth Intergovernmental Panel on Climate Change report states that climate change has altered the distribution of some infectious disease vectors.

19. OTHER HAZARDS OF INTEREST
After reviewing the previous plan and considering options for other hazards of interest to address, the Steering Committee selected a limited number of hazards of interest to include in this update of the Ventura County Multi-Jurisdictional Hazard Mitigation Plan. The sections below provide short profiles of each hazard of interest, including a qualitative discussion of their potential impact in Ventura County.
No formal risk assessment was performed, no mitigation actions have been developed to address them, and the hazards are not included in the risk ranking. However, all planning partners for this plan should be aware of these hazards and take steps to reduce the risks they present whenever it is practical to do so.
19.1 AGRICULTURAL AND BIOLOGICAL
19.1.1 Overview
Agricultural infestation generally involves the artificial introduction of an insect, disease, vertebrate, or weed pest. These pests are particularly destructive to local agricultural crops because they have no natural enemies to keep them under control. The type and severity of an agricultural infestation will vary based on many factors, including weather, crop diversity, and proximity to urban areas.
The onset for an agricultural infestation can be rapid. Controlling its spread is critical to limiting the impacts of the infestation. Methods for detecting, limiting, and eradicating exotic pests include delimitation trapping, quarantining the area and preventing the shipment of products from the designated area, aerial and ground application of pesticides, and in extreme cases, premature harvest and/or crop destruction. Duration is largely affected by the degree to which the infestation is aggressively controlled but is commonly more than a week. The warning time needed to control infestation is typically more than 24 hours. Maximizing warning time is also critical for reducing damage from this hazard.
Ventura County’s agriculture industry provides a significant base to the County’s economy. The agricultural output of Ventura County in 2020 reached almost $2 billion and encompassed more than 96,500 acres of irrigated cropland (Ventura County Agricultural Commissioner 2020). Ventura County is one of the top 10 agricultural counties in California. The impact of infestation by a pest or disease can include economic losses due to crop losses from pest damage, limitations on the ability to export products from the area, and increased costs for pest control.
Many pests not only damage the agricultural economy but also affect residential areas and open space.
Damage to landscape plants and vegetable gardens can be significant. 268
Ventura County Multi-Jurisdictional Hazard Mitigation Plan 19-2
19.1.2 Identified Agricultural and Biological Hazards
The Ventura County Agricultural Commissioner and the USDA have identified agricultural and biological hazards that currently affect the County or have the potential to do so in the future. Many of these are listed in Table 19-1.
Table 19-1. Agricultural and Biological Hazards That Threaten Ventura County Type Description
Invertebrates
Quagga Mussels A mollusk that covers hard surfaces in waterways. It clogs water infrastructure, covers boats, disrupts the food chain for native species, and releases toxins that affect other species.
Insects
Asian Citrus Psyllid An insect that causes damage to citrus plants and is a carrier of Huanglongbing disease.
Glassy Winged Sharpshooter An insect that transmits a bacterial disease (Pierce’s Disease) that can seriously damage grapevines Light Brown Apple Moth A tortricid leafroller that affects over 2,000 types of plants.
Mediterranean Fruit Fly An insect that infests more than 300 varieties of fruits, vegetables, and nuts by laying eggs in the produce. The larvae feed on the produce, ruining it for human consumption.
Shot Hole Borer An invasive beetle that attacks over 110 kinds of trees. These tiny beetles tunnel into host trees and spread Fusarium Dieback.
Invasive Weeds
Artichoke Thistle An invasive weed with an aggressive root system.
Arundo Grass Tall perennial grass that forms dense growth, choking out other plants.
Dalmation Todflax Displaces native plants and may increase soil erosion and surface runoff.
Distaff Thistle Crowds out grasses and native species.
Geraldton Carnation Spurge Produces a toxic sap and has allelopathic properties that reduce germination of native plants.
Russian Knapweed Aggressive plant with allelopathic effects (releases a substance that does not allow other plants to grow).
Scotch Thistle Dense growths of the spiny plants interrupt grazing lands for livestock and wildlife.
Silverleaf Nightshade Noxious weed competes with crops, interferes with livestock, acts as a host for insects and plant diseases, and spreads by forming dense colonies from its extensive root system as well as by propagation of seeds.
Skeletonweed Deep rooted noxious weed with minimal feed value that crowds out native grasses and forage for livestock and wildlife.
Spotted Knapweed A highly invasive weed that can reduce the availability of desirable forage for livestock operations, degrade wildlife habitats, and hinder reforestation and landscape restoration efforts.
Stinkweed Rapidly spreading invasive weed.
Tree Spurge Small invasive shrub that has an economic impact on crop production in the County.
Diseases
Charcoal Rot A fungal disease that affects strawberries.
Fusarium Dieback A fungal disease that disrupts the transport of water and nutrients inside the tree, leading to branch dieback and overall decline
Huanglongbing A disease spread by the Asian citrus psyllid that kills citrus trees. It has no known cure.
Pierce’s Disease A bacteria-caused disease spread by the Glassy Winged Sharpshooter. Pierce’s Disease blocks the water-conducting system in grapevines.
Sudden Oak Death A tree disease caused by the fungus-like plant pathogen Phytophthora ramorum. It kills oaks, rhododendrons, camellias, and other common horticulture plants. 269
Other Hazards of Interest
19-3
19.1.3 Location, Extent and Magnitude
Ventura County’s agricultural areas are most susceptible to insect pests, agriculture biological diseases, and invasive weeds. Range land, open spaces, and areas affected by wildfire are also susceptible to many of the invasive weeds. Quagga mussels are found in Lake Piru and the Santa Clara River.
Injurious pests commonly enter Ventura County in a number of ways. They may, for example, be inadvertently shipped by a private individual in an infested plant, fruit, or vegetable. When the package is received and the article is found to contain pests, the recipient throws it out and the pests multiply and infest nearby agricultural crops, waterways, or urban properties. Pests can also travel easily on plants and plant parts shipped from uncertified and unlicensed nurseries; on plants offered for sale at swap meets and other open air markets; or in vehicles or luggage. Inspectors from the Agricultural Commissioner’s office inspect incoming plants at nurseries, farmer’s markets, and swap meets to check for the presence of pests not occurring in this area.
Future agricultural and waterway infestations in Ventura County are likely based on past occurrences.
Based on previous history, infestations causing widespread damage have occurred about once every 10 to 20 years. Another factor increasing the likelihood of future infestations is the mild climate in Ventura County, which increases the ability of pests to proliferate.
The extent of a devastating event would depend on many factors, including the specific pest introduced, climatic conditions at the time of introduction, fluctuations in funding for pest detection and eradication, and public pressure regarding aerial and ground applications of pesticides proximate to urban areas.
19.2 PANDEMIC
19.2.1 Overview
According to the World Health Organization, a pandemic involves the international spread of a new disease. While an epidemic remains limited to one city, region, or country, a pandemic spreads beyond national borders and possibly worldwide. Authorities consider a disease to be an epidemic when the number of people with the infection is higher than the forecast number within a specific region. A pandemic is an epidemic that becomes widespread in several countries at the same time. A pandemic affects a higher number of people and can be more deadly than an epidemic.
A new virus strain or subtype that easily transmits between humans can cause a pandemic. Bacteria that become resistant to antibiotic treatment may also be behind the rapid spread. Sometimes, pandemics occur when new diseases develop the ability to spread rapidly, such as COVID-19. Humans may have little or no immunity against a new virus. Often, a new virus cannot spread between animals and people. However, if the disease changes or mutates, it may start to spread easily, and a pandemic may result. Seasonal flu epidemics generally occur because of a viral subtype that is already circulating among people. Novel subtypes, such as COVID-19, generally cause pandemics. These subtypes will not previously have circulated among humans. A pandemic can lead to social disruption, economic loss, and general hardship on a wide scale (Felman 2020). 270

As this plan is being prepared, Ventura County, the State of California, and the rest of the world are still dealing with impacts of the global COVID-19 pandemic. In March 2020, Ventura County was included in the FEMA Major Disaster Declaration for the COVID-19 pandemic. As of December 2021, about 107,000 people, or 7.86 percent of the Ventura County population, have had the disease. More than 1,200 people, or 0.14 percent of the population, have died from the disease. Over 572,000 residents are fully vaccinated. Figure 19-1 shows the COVID-19 case rates among the fully vaccinated and unvaccinated populations for the last half of 2021.

19.2.3 Location, Extent and Magnitude
Health hazards that affect the residents of Ventura County may arise in a variety of situations, such as during a communicable disease outbreak or after a natural disaster. All populations in Ventura County are susceptible to pandemic events. Populations who are young or elderly or have compromised immune systems are likely to be more vulnerable. The relative ease of world-wide travel ensures that all countries are vulnerable to pandemic events at any time.

20. PLANNING AREA RISK RANKING
A risk ranking was performed for the hazards of concern described in this plan. This risk ranking assesses the probability of each hazard’s occurrence as well as its likely impact on the people, property, and economy of the planning area. The risk ranking was conducted via facilitated brainstorming sessions with the Steering Committee. Estimates of risk were generated with data from Hazus using methodologies promoted by FEMA. The results are used in establishing mitigation priorities. This chapter presents results for all of Ventura County. Results for individual municipalities are provided in Appendix D and in the Volume 2 annexes for individual planning partners.
20.1 PROBABILITY OF OCCURRENCE
The probability of occurrence of a hazard is indicated by a probability factor based on likelihood of annual occurrence:
High—Hazard event is likely to occur within 25 years (Probability Factor = 3) Medium—Hazard event is likely to occur within 100 years (Probability Factor =2) Low—Hazard event is not likely to occur within 100 years (Probability Factor =1) No exposure—There is no probability of occurrence (Probability Factor = 0) The assessment of hazard frequency is generally based on past hazard events in the area. Figure 20-1 summarizes the probability assessment for each hazard of concern for this plan.

20.2 IMPACT
Hazard impacts were assessed in three categories: impacts on people, impacts on property and impacts on the local economy. Numerical impact factors were assigned as follows:
People—Values were assigned based on the percentage of the total population exposed to the hazard event. The degree of impact on individuals will vary and is not measurable, so the calculation assumes for simplicity and consistency that all people exposed to a hazard because they live in a hazard zone will be equally impacted when a hazard event occurs. It should be noted that planners can use an element of subjectivity when assigning values for impacts on people. Impact factors were assigned as follows:
High—50 percent or more of the population is exposed to a hazard (Impact Factor = 3) Medium—25 percent to 49 percent of the population is exposed to a hazard (Impact Factor = 2)
Low—25 percent or less of the population is exposed to the hazard (Impact Factor = 1) No impact—None of the population is exposed to a hazard (Impact Factor = 0) Property—Values were assigned based on the percentage of the total property value exposed to the hazard event:
High—30 percent or more of the total assessed property value is exposed to a hazard (Impact Factor = 3)
Medium—15 percent to 29 percent of the total assessed property value is exposed to a hazard (Impact Factor = 2)
Low—14 percent or less of the total assessed property value is exposed to the hazard (Impact Factor = 1)
No impact—None of the total assessed property value is exposed to a hazard (Impact Factor = 0)
Economy—Values were assigned based on the percentage of the total property value vulnerable to the hazard event. Values represent estimates of the loss from a major event of each hazard in comparison to the total assessed value of the property exposed to the hazard.
For some hazards, such as wildfire, landslide and severe weather, vulnerability was considered to be the same as exposure due to the lack of loss estimation tools specific to those hazards.
Loss estimates separate from the exposure estimates were generated for the earthquake and flood hazards using Hazus.
High—Estimated loss from the hazard is 20 percent or more of the total assessed property value (Impact Factor = 3)
Medium—Estimated loss from the hazard is 10 percent to 19 percent of the total assessed property value (Impact Factor = 2)
Low—Estimated loss from the hazard is 9 percent or less of the total assessed property value (Impact Factor = 1)
No impact—No loss is estimated from the hazard (Impact Factor = 0) The impacts of each hazard category were assigned a weighting factor to reflect the significance of the impact. These weighting factors are consistent with those typically used for measuring the benefits of hazard mitigation actions: impact on people was given a weighting factor of 3; impact on property was given a weighting factor of 2; and impact on the operations was given a weighting factor of 1.
Figure 20-2 and Figure 20-3 summarize the unweighted and weighted impact factors, respectively, for each hazard.

20-3
Figure 20-2. Impact Factors for Hazards of Concern
Figure 20-3. Weighted Impact Factors for Hazards of Concern
20.3 RISK RATING AND RANKING
The risk rating for each hazard was determined by multiplying the probability factor by the sum of the weighted impact factors for people, property, and operations, as summarized in Figure 20-4.
Based on these ratings, a priority of high, medium, or low was assigned to each hazard. The hazards ranked as being of highest concern are dam failure, landslide, and earthquake. Hazards ranked as being of medium concern are flood, severe storms, severe weather, and wildfire. The hazards ranked as being of lowest concern are drought, sea-level rise/coastal erosion, and tsunami. Figure 20-5 shows the hazard risk ranking.

21-1
21. VISION STATEMENT, GOALS AND OBJECTIVES
Hazard mitigation plans must identify goals for reducing long-term vulnerabilities to identified hazards (44 CFR Section 201.6(c)(3)(i)). The Steering Committee reviewed the previous plan and noted that neither a vision statement nor a list of objectives was part of the plan. The goals in the previous plan needed to be expanded to better reflect the purpose of this plan update.
The vision statement, goals, objectives, and actions in this plan all support each other. Goals were selected to support the vision statement. Objectives were selected that meet multiple goals. Actions (presented in Chapter 23) were prioritized based on their ability to meet multiple objectives.
21.1 VISION STATEMENT
A vision statement focuses the range of objectives and actions to be considered. A vision statement is not a goal because it does not describe a hazard mitigation outcome and it is broader than a hazard- specific objective. The vision statement for this hazard mitigation plan is as follows:
The Ventura County Multi-Jurisdictional Hazard Mitigation Plan will establish and promote a comprehensive mitigation strategy and efforts to equitably reduce risk and increase the resiliency of the community and environment from natural hazards.
21.2 GOALS
The following are the mitigation goals for this plan:
1. Protect life, property, and the environment, and minimize displacement due to natural hazards events.
2. Effectively communicate natural hazard risks and mitigation strategies to the whole community.
3. Pursue development and implementation of feasible, cost-effective, and environmentally sound hazard mitigation measures.
4. Prioritize multi-objective hazard mitigation actions and those that reduce risk to vulnerable communities.
5. Coordinate with other plans and programs that can support or enhance hazard mitigation.
6. Enhance the County’s capability and capacity to prepare for, respond to, and recover from the impacts of natural hazards.
7. Proactively anticipate the risks of future impacts from hazards.
8. Increase the County’s adaptive capacity to reduce risk from hazard impacts. 280
Ventura County Multi-Jurisdictional Hazard Mitigation Plan 21-2
9. Promote proactive, self-sufficient mitigation and response abilities.
10. Reduce risk to and increase the resilience of critical infrastructure and community lifelines.
21.3 OBJECTIVES
Each selected objective meets multiple goals, serving as a stand-alone measurement of the effectiveness of a mitigation action, rather than as a subset of a goal. The objectives also are used to help establish priorities. The objectives are as follows:
1. Utilize the best available data, science, and technology to identify and communicate the risk exposure to hazards to state, regional, and local agencies, as well as the private sector and non-profit groups.
2. Support efforts to improve the resilience of community lifelines in socially vulnerable communities.
3. Enhance supply chain diversity and improved resilience by supporting local food and energy production and increased multi-modal transportation.
4. Research, develop, promote, adopt, and enforce codes and standards to preserve life and property that are affordable and feasible to implement.
5. Promote and implement measures to mitigate the risk of wildfires, such as greenbelts and fire breaks around communities and along roadways.
6. Support the protection of vital records, and strengthen or replace buildings, infrastructure, and lifelines to minimize post-disaster disruption and facilitate short-term and long-term recovery.
7. Improve and expand systems that provide warning and emergency communications to the whole community.
8. Continue developing and strengthening inter-jurisdictional coordination and cooperation in the area of emergency services.
9. Promote and implement the retrofit or replacement of at-risk structures and lifelines to increase community resilience.
10. Incentivize mitigation measures for high-risk and repetitive loss areas to address repairs, major alterations, development plans, and practices to increase community resilience.
11. Reduce repetitive property losses due to hazard impacts through acquisition, retrofitting, design, and updated construction and land use regulations.
12. Encourage and support leadership within the private sector, non-profit agencies, and community-based organizations to promote and implement local hazard mitigation activities.
13. Proactively manage and care for natural resources, including grasslands, forests, oak woodlands, riparian forests, stream channels, coastal wetlands, and beaches, to enhance their ability to withstand and recover from natural disasters and minimize public safety risks.
14. Support hazard mitigation measures that promote and enhance natural processes.
15. Support hazard mitigation measures, where feasible, that utilize nature-based practices and solutions (e.g., holistic watershed management and green belts) and support and enhance natural processes.
281
Vision Statement, Goals and Objectives
21-3
16. Encourage the creation of financial and regulatory incentives to motivate stakeholders such as homeowners, private sector businesses, and non-profit community organizations to mitigate hazards and risks.
17. Conduct public outreach activities that increase community awareness and understanding of hazard risk, mitigation options, and preparedness strategies.
18. Minimize impacts of hazard events on the economic drivers for the County.
19. Align the hazard mitigation plan with state mitigation plans; city and county general, community, capital improvement plans; special-purpose district plans; and climate action, resilience, and adaptation plans.
282
283
22-1
22. MITIGATION BEST PRACTICES
22.1 MITIGATION BEST PRACTICES
Catalogs of hazard mitigation best practices were developed that present a broad range of alternatives to be considered for use by the planning partners, in compliance with 44 CFR (Section 201.6(c)(3)(ii)).
One catalog was developed for each hazard of concern evaluated in this plan. The catalogs present alternatives that are categorized in two ways:
By who would have responsibility for implementation:
Individuals (personal scale)
Businesses (corporate scale)
Government (government scale).
By what the alternative would do:
Manipulate the hazard
Reduce exposure to the hazard
Reduce vulnerability to the hazard
Build local capacity to respond to or prepare for the hazard.
Hazard mitigation actions recommended in this plan were selected from an analysis of the alternatives presented in the catalogs. The catalogs provide a baseline of mitigation alternatives that are backed by a planning process, are consistent with the established goals and objectives, and are generally within the capabilities of the planning partners to implement. They provide a list of what could be considered to reduce risk from natural hazards. Not all actions listed are feasible for this plan. Planning partners selected actions based their ability to implement the action.

22.2 ADAPTIVE CAPACITY
Adaptive capacity is defined as “the ability of systems, institutions, humans and other organisms to adjust to potential damage, to take advantage of opportunities, or to respond to consequences” (Intergovernmental Panel on Climate Change 2021). In addition to hazard-specific capacity building, the following list provides general alternatives that planning partners considered to build capacity for adapting to both current and future risks (Cal OES 2020).
Incorporate climate change adaptation into relevant local and regional plans and projects.
Establish a climate change adaptation and hazard mitigation public outreach and education program.
Build collaborative relationships between regional entities, neighboring communities, and private and non-profit partners to promote complementary adaptation and mitigation strategy development and regional approaches.
Establish an ongoing monitoring program to track local and regional climate impacts and adaptation strategy effectiveness.
Increase participation of low-income, immigrant, non-English-speaking, racially and ethnically diverse, and special-needs residents in planning and implementation.
Ask local employers and business associations to participate in local efforts to address climate change and natural hazard risk reduction.
Conduct a communitywide assessment and develop a program to address health, socioeconomic, and equity vulnerabilities.
Focus planning and intervention programs on neighborhoods that currently experience social or environmental injustice or bear a disproportionate burden of potential public health impacts.
Use performance metrics and data to evaluate and monitor the impacts of climate change and natural hazard risk reduction strategies on public health and social equity.
Develop coordinated plans for mitigating future flood, landslide, and related impacts through concurrent adoption of updated general plan safety elements and local hazard mitigation plans.
Update safety elements to reflect existing hazards and projected climate change impacts on hazards.
Implement general plan safety elements through zoning and subdivision practices that restrict development in floodplains, landslide, and other natural hazard areas.
Identify and protect locations where native species may shift or lose habitat due to climate change impacts (sea-level rise, loss of wetlands, warmer temperatures, drought).
Collaborate with agencies managing public lands to identify, develop, or maintain corridors and linkages between undeveloped areas.
Promote economic diversity.
Incorporate consideration of climate change impacts as part of infrastructure planning and operations.
Conduct a climate impact assessment on community infrastructure. 294

23. RECOMMENDED PLANNING-AREA-WIDE ACTIONS
23.1 RECOMMENDED MITIGATION ACTIONS FOR ALL PARTNERS
The Steering Committee reviewed the catalogs of hazard mitigation alternatives and selected planning- area-wide actions to be included in a hazard mitigation action plan for all planning partners. The selection of area-wide actions was based on the risk assessment of identified hazards of concern and the defined hazard mitigation goals and objectives. Table-23-1 lists the recommended hazard mitigation actions that make up the action plan. The timeframe indicated in the table is defined as follows:
Short Term = to be completed in 1 to 5 years
Long Term = to be completed in greater than 5 years
Ongoing = currently being funded and implemented under existing programs.
Additional jurisdiction-specific action plans for each planning partner are included in the partner annexes in Volume 2 of this hazard mitigation plan.

23.2 AREA-WIDE 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
296
Ventura County Multi-Jurisdictional Hazard Mitigation Plan 23-2
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.
23.2.1 Benefit and Cost
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.
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.
23.2.2 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 297
Recommended Planning-Area-Wide Actions
23-3
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.
23.2.3 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.

23.3 CLASSIFICATION OF AREA-WIDE MITIGATION ACTIONS
Each recommended action was classified based on the hazard it addresses and the type of mitigation it involves. Table 23-3 shows these classifications. Mitigation types used for this categorization 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.

24. PLAN ADOPTION AND MAINTENANCE
24.1 PLAN ADOPTION
A hazard mitigation plan must document formal adoption by the governing body of the jurisdiction requesting federal approval of the plan (44 CFR, Section 201.6.c.5). For multi-jurisdictional plans, each jurisdiction requesting approval must document that is has been formally adopted. This plan will be submitted for a pre-adoption review to Cal OES and FEMA Region IX prior to adoption. Once pre- adoption approval has been provided, all planning partners will formally adopt the plan. DMA compliance and its benefits cannot be achieved until the plan is adopted. Copies of the FEMA approval and planning partner resolutions adopting this plan can be found in Appendix F of this volume.
24.2 PLAN MAINTENANCE STRATEGY
This section describes a formal plan maintenance process to ensure that the hazard mitigation plan remains an active and relevant document. It includes an explanation of the responsibilities of a hazard mitigation plan Project Management Team and the planning partners. It outlines steps to ensure that the plan remains an active and relevant document and that any improvements and revisions to the hazard mitigation plan occur in a well-managed, efficient, and coordinated manner. Requirements for monitoring, evaluating, and updating the hazard mitigation plan include the following:
44 CFR 201.6, Local Mitigation Plans (Element A)—Inclusion of a description of the method and schedule for keeping the plan current (monitoring, evaluating, and updating the mitigation plan within a 5-year cycle. (Requirement § 201.6(c)(4)(1))
CRS 510 Floodplain Management Planning, CRS Step 10:
A. Procedures to monitor and recommend revisions.
B. Same planning committee or successor committee that qualifies under Section 511.a.2 (a) does the evaluation.
A Project Management Team, composed of Ventura County staff members, will take the lead on monitoring, evaluating, and updating the hazard mitigation plan over the 5-year performance period.
Table 24-1 summarizes the plan maintenance strategy over the 5-year performance period of the plan.
The sections below further describe each element.

a. Responsible lead party may designate an alternate. Jurisdictional points of contact identified in Volume 2 have support responsibility.
24.2.1 Plan Monitoring
Ventura County Sheriff’s OES will be the lead agency responsible for oversight and the Project Management Team will support plan monitoring, evaluation, and the plan update schedule. Each planning partner will monitor plan implementation by tracking the status of mitigation actions in its action plan. Staff or departments with primary responsibility are identified in each jurisdictional annex (see Volume 2).
24.2.2 Plan Evaluation
Plan evaluation will be a shared responsibility among all planning partners identified as lead agencies in the area-wide and jurisdiction-specific action plans. The plan will be analyzed for which goals and objectives were achieved. Additionally, a review of any changes in risk over the performance period will be analyzed by the degree to which those changes may impact and require revision to the mitigation goals and objectives and how they are incorporated into jurisdictional plans, policies and programs.
Review of the hazard mitigation plan can include the following:
301
Plan Adoption and Maintenance
24-3
Discussion of hazard events that occurred during the prior year and their impact on the planning area
Impact of potential grant opportunities on the implementation of mitigation actions Re-evaluation of the action plans to determine if the timeline for identified actions needs to be amended (such as changing a long-term action to a short-term action because of funding availability)
Recommendations for new actions
Impact of any other planning programs or initiatives that involve hazard mitigation
24.2.3 Grant Monitoring and Coordination
Ventura County Sheriff’s OES, in consultation with the planning partners, will identify hazard mitigation grant funding opportunities and assume lead responsibility for planning and facilitating grant opportunity calls or meetings. The Project Management Team will communicate and coordinate with the planning partners to review the hazard mitigation plan and pursue a strategy to capture grant funding.
24.2.4 Plan Update
FEMA requires the hazard mitigation plan to be revised and resubmitted for review and approval by Cal OES and FEMA prior to the five-year anniversary date of the plan’s adoption in order to remain eligible for benefits under the DMA (44 CFR, Section 201.6(d)(3)). To meet this timeline, at the end of year 3 (2025), Ventura County Sheriff’s OES, with support from the Project Management Team, will coordinate with the planning partners to identify a grant funding opportunity for the update. Grant funding for the update will be obtained by the end of year 4 (2026). This cycle may be accelerated to less than five years based on the following triggers:
A federal disaster declaration that impacts Ventura County A hazard event that causes loss of life
A comprehensive update of the Ventura County General Plan The revision process may include the following elements, as required by FEMA at the time of the next update:
The revision process will be convened through a new steering committee The hazard risk assessment will be reviewed and, if necessary, revised using best available information and technologies
The action plan will be reviewed for any actions completed, ongoing, or withdrawn, and will be reconciled to account for changes in the risk assessment or new policies identified under other plans (such as the General Plan)
The draft plan revision will be sent to appropriate agency departments and divisions for comment
The public will be given an opportunity to comment on the revised plan prior to adoption The Ventura County Board of Supervisors will adopt the updated plan once the reviews by Cal OES and FEMA have been conducted
302
Ventura County Multi-Jurisdictional Hazard Mitigation Plan 24-4
24.2.5 Integration with Other Planning Mechanisms
The information on hazard, risk, vulnerability, and mitigation contained in this plan is based on the best science and technology available at the time this plan was prepared. The planning partners, through adoption of General Plans and zoning ordinances, have planned for the impact of natural hazards. The hazard mitigation plan development process provided them with an opportunity to review and expand on policies contained within these planning mechanisms. The planning partners used their general plans and the hazard mitigation plan as complementary documents that work together to achieve the goal of reducing risk exposure to the citizens of the planning area. An update to a General Plan may trigger an update to the hazard mitigation plan.
All municipal planning partners have committed to creating a linkage between the hazard mitigation plan and their individual General Plans within one of their identified mitigation actions. Other planning processes and programs to be coordinated with the recommendations of the hazard mitigation plan may include:
Climate action plans
Emergency operations plans
Resilience plans
Recovery plan
Emergency response plans
Training and exercise of emergency response plans
Capital improvement programs
Municipal codes
Community design guidelines
Stormwater management programs
Debris management plans
Water-efficient landscape design guidelines
Water system vulnerability assessments
Community wildfire protection plans
Comprehensive flood hazard management plans
Community development block grant-disaster recovery action plans Public information/education plans.
Some action items do not need to be implemented through regulation. Instead, these items can be implemented through the creation of new educational programs, continued interagency coordination, or improved public participation. As information becomes available from other planning mechanisms that can enhance this plan, that information can be incorporated via the next hazard mitigation plan update.
For the special purpose district planning partners to this plan, identified planning capabilities include capital facility plans, emergency operations plan, continuity of operations plans, and community wildfire 303
Plan Adoption and Maintenance
24-5
protection plans. Special purpose districts do not have land use authority, so integration with land use plans is not a capability for districts. However, for the planning capabilities that the districts do possess, they will integrate where appropriate relevant sections of this plan when those plans are scheduled for updates. This has already occurred for most of the district planning partners as indicated in Volume 2 of this plan.
24.2.6 Continuing Public Involvement
The public will continue to be apprised of the plan’s progress through the www.readyventuracounty.org website. The website will house the final plan and the StoryMap and will provide information regarding the plan, plan implementation, and plan update process. The website will continue to be updated as additional information becomes available. This may include examples of local mitigation in action, planning partner updates, resources, and public participation opportunities.
Upon initiation of future update processes, a new public involvement strategy will be developed. This strategy will be based on the needs and capabilities of Ventura County and its planning partners at the time of the update and will include web, social media, and the use of other local media outlets in the planning area.

B. FEDERAL AND STATE AGENCIES, PROGRAMS AND
REGULATIONS
Existing laws, ordinances, plans and programs at the federal and state level can support or impact hazard mitigation actions identified in this plan. Hazard mitigation plans are required to include a review and incorporation, if appropriate, of existing plans, studies, reports, and technical information as part of the planning process (44 CFR, Section 201.6(b)(3)). The following federal and state programs have been identified as programs that may interface with the actions identified in this plan. Each program enhances capabilities to implement mitigation actions or has a nexus with a mitigation action in this plan. Information presented in this section can be used to review local capabilities to implement the actions found in the jurisdictional annexes of Volume 2. Each planning partner has individually reviewed existing local plans, studies, reports, and technical information in its jurisdictional annex, presented in Volume 2.
FEDERAL
Americans with Disabilities Act
The Americans with Disabilities Act (ADA) seeks to prevent discrimination against people with disabilities in employment, transportation, public accommodation, communications, and government activities. Title II of the ADA deals with compliance with the Act in emergency management and disaster-related programs, services, and activities. It applies to state and local governments as well as third parties, including religious entities and private nonprofit organizations.
The ADA has implications for sheltering requirements and public notifications. During an emergency alert, officials must use a combination of warning methods to ensure that all residents have all necessary information. Those with hearing impairments may not hear radio, television, sirens, or other audible alerts, while those with visual impairments may not see flashing lights or other visual alerts.
Two technical documents for shelter operators address physical accessibility needs of people with disabilities, as well as medical needs and service animals.
The ADA intersects with disaster preparedness programs in regards to transportation, social services, temporary housing, and rebuilding. Persons with disabilities may require additional assistance in evacuation and transit (e.g., vehicles with wheelchair lifts or paratransit buses). Evacuation and other response plans should address the unique needs of residents. Local governments may be interested in implementing a special-needs registry to identify the home addresses, contact information, and needs for residents who may require more assistance.
354
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-2
FEMA hazard mitigation project grant applications require full compliance with applicable federal acts.
Any action identified in this plan that falls within the scope of this act will need to meet its requirements.
Bureau of Land Management
The U.S. Bureau of Land Management (BLM) funds and coordinates wildfire management programs and structural fire management and prevention on BLM lands. BLM works closely with the Forest Service and state and local governments to coordinate fire safety activities. The Interagency Fire Coordination Center in Boise, Idaho serves as the center for this effort.
Civil Rights Act
The Civil Rights Act of 1964 prohibits discrimination based on race, color, religion, sex or nation origin and requires equal access to public places and employment. The Act is relevant to emergency management and hazard mitigation in that it prohibits local governments from favoring the needs of one population group over another. Local government and emergency response must ensure the continued safety and well-being of all residents equally, to the extent possible. FEMA hazard mitigation project grant applications require full compliance with applicable federal acts. Any action identified in this plan that falls within the scope of this act will need to meet its requirements.
Clean Water Act
The federal Clean Water Act (CWA) employs regulatory and non-regulatory tools to reduce direct pollutant discharges into waterways, finance municipal wastewater treatment facilities, and manage polluted runoff. These tools are employed to achieve the broader goal of restoring and maintaining the chemical, physical, and biological integrity of the nation’s surface waters so that they can support “the protection and propagation of fish, shellfish, and wildlife and recreation in and on the water.” Evolution of CWA programs over the last decade has included a shift from a program-by-program, source-by-source, and pollutant-by-pollutant approach to more holistic watershed-based strategies.
Under the watershed approach, equal emphasis is placed on protecting healthy waters and restoring impaired ones. Numerous issues are addressed, not just those subject to CWA regulatory authority.
Involvement of stakeholder groups in the development and implementation of strategies for achieving and maintaining water quality and other environmental goals is a hallmark of this approach.
The CWA is important to hazard mitigation in several ways. There are often permitting requirements for any construction within 200 feet of water of the United States, which may have implications for mitigation projects identified by a local jurisdiction. Additionally, CWA requirements apply to wetlands, which serve important functions related to preserving and protecting the natural and beneficial functions of floodplains and are linked with a community’s floodplain management program. Finally, the National Pollutant Discharge Elimination System is part of the CWA and addresses local stormwater management programs. Stormwater management plays a critical role in hazard mitigation by addressing urban drainage or localized flooding issues within jurisdictions.
FEMA hazard mitigation project grant applications require full compliance with applicable federal acts.
Any action identified in this plan that falls within the scope of this act will need to meet its requirements. 355
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-3
Community Development Block Grant Disaster Resilience Program In response to disasters, Congress may appropriate additional funding for the U.S. Department of Housing and Urban Development Community Development Block Grant programs to be distributed as Disaster Recovery grants (CDBG-DR). These grants can be used to rebuild affected areas and provide seed money to start the recovery process. CDBG-DR assistance may fund a broad range of recovery activities, helping communities and neighborhoods that otherwise might not recover due to limited resources. CDBG-DR grants often supplement disaster programs of FEMA, the Small Business Administration, and the U.S. Army Corps of Engineers. Housing and Urban Development generally awards noncompetitive, nonrecurring CDBG-DR grants by a formula that considers disaster recovery needs unmet by other federal disaster assistance programs. To be eligible for CDBG-DR funds, projects must meet the following criteria:
Address a disaster-related impact (direct or indirect) in a presidentially declared county for the covered disaster
Be a CDBG-eligible activity (according to regulations and waivers) Meet a national objective.
Incorporating preparedness and mitigation into these actions is encouraged, as the goal is to rebuild in ways that are safer and stronger. CDBG-DR funding is a potential alternative source of funding for actions identified in this plan.
Community Rating System
The CRS is a voluntary program within the NFIP that encourages floodplain management activities that exceed the minimum NFIP requirements. Flood insurance premiums are discounted to reflect the reduced flood risk resulting from community actions meeting the following three goals of the CRS:
Reduce flood losses.
Facilitate accurate insurance rating.
Promote awareness of flood insurance.
For participating communities, flood insurance premium rates are discounted in increments of 5 percent. For example, a Class 1 community would receive a 45 percent premium discount, and a Class 9 community would receive a 5 percent discount. (Class 10 communities are those that do not participate in the CRS; they receive no discount.) The discount partially depends on location of the property. Properties outside the special flood hazard area receive smaller discounts: a 10-percent discount if the community is at Class 1 to 6 and a 5-percent discount if the community is at Class 7 to 9.
The CRS classes for local communities are based on 18 creditable activities in the following categories:
Public information
Mapping and regulations
Flood damage reduction
Flood preparedness.
356
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-4
CRS activities can help to save lives and reduce property damage. Communities participating in the CRS represent a significant portion of the nation’s flood risk; over 66 percent of the NFIP’s policy base is located in these communities. Communities receiving premium discounts through the CRS range from small to large and represent a broad mixture of flood risks, including both coastal and riverine flood risks.
Disaster Mitigation Act
The DMA is the current federal legislation addressing hazard mitigation planning. It emphasizes planning for disasters before they occur. It specifically addresses planning at the local level, requiring plans to be in place before Hazard Mitigation Assistance grant funds are available to communities. This plan is designed to meet the requirements of DMA, improving eligibility for future hazard mitigation funds.
Emergency Relief for Federally Owned Roads Program
The U.S. Forest Service’s Emergency Relief for Federally Owned Roads Program was established to assist federal agencies with repair or reconstruction of tribal transportation facilities, federal lands transportation facilities, and other federally owned roads that are open to public travel and have suffered serious damage by a natural disaster over a wide area or by a catastrophic failure. The program funds both emergency and permanent repairs. Eligible activities under this program meet some of the goals and objectives for this plan and the program is a possible funding source for actions identified in this plan.
Emergency Watershed Program
The USDA Natural Resources Conservation Service (NRCS) administers the Emergency Watershed Protection (EWP) Program, which responds to emergencies created by natural disasters. Eligibility for assistance is not dependent on a national emergency declaration. The program is designed to help people and conserve natural resources by relieving imminent hazards to life and property caused by floods, fires, windstorms, and other natural occurrences. EWP is an emergency recovery program.
Financial and technical assistance are available for the following activities:
Remove debris from stream channels, road culverts, and bridges Reshape and protect eroded banks
Correct damaged drainage facilities
Establish cover on critically eroding lands
Repair levees and structures
Repair conservation practices.
This federal program could be a possible funding source for actions identified in this plan. 357
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-5
Endangered Species Act
The federal Endangered Species Act (ESA) was enacted in 1973 to conserve species facing depletion or extinction and the ecosystems that support them. The act sets forth a process for determining which species are threatened and endangered and requires the conservation of the critical habitat in which those species live. The ESA provides broad protection for species of fish, wildlife and plants that are listed as threatened or endangered. Provisions are made for listing species, as well as for recovery plans and the designation of critical habitat for listed species. The ESA outlines procedures for federal agencies to follow when taking actions that may jeopardize listed species and contains exceptions and exemptions. It is the enabling legislation for the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Criminal and civil penalties are provided for violations of the ESA and the Convention.
Federal agencies must seek to conserve endangered and threatened species and use their authorities in furtherance of the ESA’s purposes. The ESA defines three fundamental terms:
Endangered means that a species of fish, animal or plant is “in danger of extinction throughout all or a significant portion of its range.” (For salmon and other vertebrate species, this may include subspecies and distinct population segments.)
Threatened means that a species “is likely to become endangered within the foreseeable future.” Regulations may be less restrictive for threatened species than for endangered species.
Critical habitat means “specific geographical areas that are…essential for the conservation and management of a listed species, whether occupied by the species or not.” Five sections of the ESA are of critical importance to understanding it:
Section 4: Listing of a Species—The National Oceanic and Atmospheric Administration Fisheries Service (NOAA Fisheries) is responsible for listing marine species; the U.S. Fish and Wildlife Service is responsible for listing terrestrial and freshwater aquatic species. The agencies may initiate reviews for listings, or residents may petition for them. A listing must be made “solely on the basis of the best scientific and commercial data available.” After a listing has been proposed, agencies receive comment and conduct further scientific reviews for 12 to 18 months, after which they must decide if the listing is warranted. Economic impacts cannot be considered in this decision, but it may include an evaluation of the adequacy of local and state protections. Critical habitat for the species may be designated at the time of listing.
Section 7: Consultation—Federal agencies must ensure that any action they authorize, fund, or carry out is not likely to jeopardize the continued existence of a listed or proposed species or adversely modify its critical habitat. This includes private and public actions that require a federal permit. Once a final listing is made, non-federal actions are subject to the same review, termed a “consultation.” If the listing agency finds that an action will “take” a species, it must propose mitigations or “reasonable and prudent” alternatives to the action; if the proponent rejects these, the action cannot proceed.
Section 9: Prohibition of Take—It is unlawful to “take” an endangered species, including killing or injuring it or modifying its habitat in a way that interferes with essential behavioral patterns, including breeding, feeding or sheltering.
Section 10: Permitted Take—Through voluntary agreements with the federal government that provide protections to an endangered species, a non-federal applicant may commit a take that 358
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-6
would otherwise be prohibited as long as it is incidental to an otherwise lawful activity (such as developing land or building a road). These agreements often take the form of a “Habitat Conservation Plan.”
Section 11: Citizen Lawsuits—Civil actions initiated by any citizen can require the listing agency to enforce the ESA’s prohibition of taking or to meet the requirements of the consultation process.
FEMA hazard mitigation project grant applications require full compliance with applicable federal acts.
Any action identified in this plan that falls within the scope of this act will need to meet its requirements.
Federal Energy Regulatory Commission Dam Safety Program The Federal Energy Regulatory Commission (FERC) cooperates with a large number of federal and state agencies to ensure and promote dam safety. More than 3,000 dams are part of regulated hydroelectric projects in the FERC program. Two-thirds of these are more than 50 years old. As dams age, concern about their safety and integrity grows, so oversight and regular inspection are important.
FERC inspects hydroelectric projects on an unscheduled basis to investigate the following:
Potential dam safety problems
Complaints about constructing and operating a project
Safety concerns related to natural disasters
Issues concerning compliance with the terms and conditions of a license.
Every five years, an independent engineer approved by the FERC must inspect and evaluate projects with dams higher than 32.8 feet (10 meters), or with a total storage capacity of more than 2,000 acre- feet.
FERC monitors seismic research and applies it in performing structural analyses of hydroelectric projects. FERC also evaluates the effects of potential and actual large floods on the safety of dams.
During and following floods, FERC visits dams and licensed projects, determines the extent of damage, if any, and directs any necessary studies or remedial measures the licensee must undertake. The FERC publication Engineering Guidelines for the Evaluation of Hydropower Projects guides the FERC engineering staff and licensees in evaluating dam safety. The publication is frequently revised to reflect current information and methodologies.
FERC requires licensees to prepare emergency action plans and conducts training sessions on how to develop and test these plans. The plans outline an early warning system if there is an actual or potential sudden release of water from a dam due to failure. The plans include operational procedures that may be used, such as reducing reservoir levels and reducing downstream flows, as well as procedures for notifying affected residents and agencies responsible for emergency management.
These plans are frequently updated and tested to ensure that everyone knows what to do in emergency situations.
359
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-7
Federal Wildfire Management Policy and Healthy Forests Restoration Act Federal Wildfire Management Policy and Healthy Forests Restoration Act (2003). These documents call for a single comprehensive federal fire policy for the Interior and Agriculture Departments (the agencies using federal fire management resources). They mandate community-based collaboration to reduce risks from wildfire.
National Dam Safety Act
Potential for catastrophic flooding due to dam failures led to passage of the National Dam Inspection Act in 1972, creation of the National Dam Safety Program in 1996, and reauthorization of the program through the Dam Safety Act in 2006. National Dam Safety Program, administered by FEMA requires a periodic engineering analysis of the majority of dams in the country; exceptions include the following:
Dams under jurisdiction of the Bureau of Reclamation, Tennessee Valley Authority, or International Boundary and Water Commission
Dams constructed pursuant to licenses issued under the Federal Power Act Dams that the Secretary of the Army determines do not pose any threat to human life or property.
The goal of this FEMA-monitored effort is to identify and mitigate the risk of dam failure so as to protect lives and property of the public. The National Dam Safety Program is a partnership among the states, federal agencies, and other stakeholders that encourages individual and community responsibility for dam safety. Under FEMA’s leadership, state assistance funds have allowed all participating states to improve their programs through increased inspections, emergency action planning, and purchases of needed equipment. FEMA has also expanded existing and initiated new training programs. Grant assistance from FEMA provides support for improvement of dam safety programs that regulate most of the dams in the United States.
National Environmental Policy Act
The National Environmental Policy Act requires federal agencies to consider the environmental impacts of proposed actions and reasonable alternatives to those actions, alongside technical and economic considerations. The National Environmental Policy Act established the Council on Environmental Quality, whose regulations (40 CFR Parts 1500-1508) set standards for compliance. Consideration and decision-making regarding environmental impacts must be documented in an environmental impact statement or environmental assessment. Environmental impact assessment requires the evaluation of reasonable alternatives to a proposed action, solicitation of input from organizations and individuals that could be affected, and an unbiased presentation of direct, indirect, and cumulative environmental impacts. FEMA hazard mitigation project grant applications require full compliance with applicable federal acts. Any action identified in this plan that falls within the scope of this act will need to meet its requirements.
National Fire Plan
The 2001 National Fire Plan was developed based on the National Fire Policy. A major aspect of the National Fire Plan is joint risk reduction planning and implementation carried out by federal, state and 360
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-8
local agencies and communities. The National Fire Plan presented a comprehensive strategy in five key initiatives:
Firefighting—Be adequately prepared to fight fires each fire season.
Rehabilitation and Restoration—Restore landscapes and rebuild communities damaged by wildfires.
Hazardous Fuel Reduction—Invest in projects to reduce fire risk.
Community Assistance—Work directly with communities to ensure adequate protection.
Accountability—Be accountable and establish adequate oversight, coordination, program development, and monitoring for performance.
National Flood Insurance Program
The National Flood Insurance Program (NFIP) makes federally backed flood insurance available to homeowners, renters, and business owners in participating communities that enact floodplain regulations. Participation and good standing under NFIP are prerequisites to grant funding eligibility under the Robert T. Stafford Act.
For most participating communities, FEMA has prepared a detailed Flood Insurance Study. The study presents water surface elevations for floods of various magnitudes, including the 1-percent-annual- chance flood and the 0.2-percent-annual-chance flood. Base flood elevations and the boundaries of the flood hazard areas are shown on Flood Insurance Rate Maps, which are the principle tool for identifying the extent and location of the flood hazard. Flood Insurance Rate Maps are the most detailed and consistent data source available, and for many communities they represent the minimum area of oversight under the local floodplain management program. In recent years, Flood Insurance Rate Maps have been digitized as Digital Flood Insurance Rate Maps, which are more accessible to residents, local governments and stakeholders.
NFIP participants must, at a minimum, regulate development in floodplain areas in accordance with NFIP criteria. Before issuing a permit to build in a floodplain, participating jurisdictions must ensure that three criteria are met:
New buildings and those undergoing substantial improvements must, at a minimum, be elevated to protect against damage by the 1-percent-annual-chance flood.
New floodplain development must not aggravate existing flood problems or increase damage to other properties.
New floodplain development must exercise a reasonable and prudent effort to reduce its adverse impacts on threatened salmonid species.
NFIP participation is limited to local governments that possess permit authority and have the ability to adopt and enforce regulations that govern land use. This does not typically apply to special purpose districts. None of the special purpose district planning partners covered by this plan are eligible to participate in the NFIP, so their action plans do not address NFIP participation. 361
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-9
National Incident Management System
The National Incident Management System (NIMS) is a systematic approach for government, nongovernmental organizations, and the private sector to work together to manage incidents involving hazards. The NIMS provides a flexible but standardized set of incident management practices.
Incidents typically begin and end locally, and they are managed at the lowest possible geographical, organizational, and jurisdictional level. In some cases, success depends on the involvement of multiple jurisdictions, levels of government, functional agencies, and emergency responder disciplines. These cases necessitate coordination across a spectrum of organizations. Communities using NIMS follow a comprehensive national approach that improves the effectiveness of emergency management and response personnel across the full spectrum of potential hazards (including natural hazards, technological hazards, and human-caused hazards) regardless of size or complexity.
Although participation is voluntary, federal departments and agencies are required to make adoption of NIMS by local and state jurisdictions a condition to receive federal preparedness grants and awards.
The content of this plan is considered to be a viable support tool for any phase of emergency management. The NIMS program is considered as a response function, and information in this hazard mitigation plan can support the implementation and update of all NIMS-compliant plans within the planning area.
National Landslide Preparedness Act
The 2021 National Landslide Preparedness Act authorized a national landslide hazards reduction program and a 3D elevation program within the USGS. This broadened the existing Landslide Hazards Program (under the Natural Hazards Mission Area) and the 3D Elevation Program (under the National Geospatial Program). The act required coordination among federal agencies through an Interagency Coordinating Committee on Landslide Hazards representing USGS and other agencies. The act calls for development of a national strategy for landslide loss reduction and a publicly accessible national landslide database of landslide hazard and risk.
Presidential Executive Order 11988, Floodplain Management Executive Order 11988 requires federal agencies to avoid to the extent possible the long and short- term adverse impacts associated with the occupancy and modification of floodplains and to avoid direct and indirect support of floodplain development wherever there is a practicable alternative. It requires federal agencies to provide leadership and take action to reduce the risk of flood loss, minimize the impact of floods on human safety, health, and welfare, and restore and preserve the natural and beneficial values of floodplains. The requirements apply to the following activities:
Acquiring, managing, and disposing of federal lands and facilities Providing federally undertaken, financed, or assisted construction and improvements Conducting federal activities and programs affecting land use, including but not limited to water and related land resources planning, regulation, and licensing. 362
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-10
Presidential Executive Order 11990, Protection of Wetlands Executive Order 11990 requires federal agencies to provide leadership and take action to minimize the destruction, loss or degradation of wetlands, and to preserve and enhance the natural and beneficial values of wetlands. The requirements apply to the following activities:
Acquiring, managing, and disposing of federal lands and facilities Providing federally undertaken, financed, or assisted construction and improvements Conducting federal activities and programs affecting land use, including but not limited to water and related land resources planning, regulation, and licensing.
All actions identified in this plan will seek full compliance with all applicable presidential executive orders.
Rural Development Program
The mission of the U.S. Department of Agriculture (USDA) Rural Development Program is to help improve the economy and quality of life in rural America. The program provides project financing and technical assistance to help rural communities provide the infrastructure needed by rural businesses, community facilities, and households. The program addresses rural America’s need for basic services, such as clean running water, sewage and waste disposal, electricity, and modern telecommunications and broadband. Loans and competitive grants are offered for various community and economic development projects and programs, such as the development of essential community facilities including fire stations. This program is a potential source of funding for actions identified in this plan.
U.S. Army Corps of Engineers Dam Safety Program
The U.S. Army Corps of Engineers operates and maintains approximately 700 dams nationwide. It is also responsible for safety inspections of some federal and non-federal dams in the United States that meet the size and storage limitations specified in the National Dam Safety Act. The Corps has inventoried dams; surveyed each state and federal agency’s capabilities, practices and regulations regarding design, construction, operation and maintenance of the dams; and developed guidelines for inspection and evaluation of dam safety. The Corps maintains the National Inventory of Dams, which contains information about a dam’s location, size, purpose, type, last inspection and regulatory status.
U.S. Army Corps of Engineers Flood Hazard Management
The following U.S. Army Corps of Engineers authorities and programs related to flood hazard management:
The Floodplain Management Services program offers 100-percent federally funded technical services such as development and interpretation of site-specific data related to the extent, duration and frequency of flooding. Special studies may be conducted to help a community understand and respond to flood risk. These may include flood hazard evaluation, flood warning and preparedness, or flood modeling.
363
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-11
For more extensive studies, the Corps of Engineers offers a cost-shared program called Planning Assistance to States and Tribes. Studies under this program generally range from $25,000 to $100,000 with the local jurisdiction providing 50 percent of the cost.
The Corps of Engineers has several cost-shared programs (typically 65 percent federal and 35 percent non-federal) aimed at developing, evaluating and implementing structural and non- structural capital projects to address flood risks at specific locations or within a specific watershed:
The Continuing Authorities Program for smaller-scale projects includes Section 205 for Flood Control, with a $7 million federal limit and Section 14 for Emergency Streambank Protection with a $1.5 million federal limit. These can be implemented without specific authorization from Congress.
Larger scale studies, referred to as General Investigations, and projects for flood risk management, for ecosystem restoration or to address other water resource issues, can be pursued through a specific authorization from Congress and are cost-shared, typically at 65 percent federal and 35 percent non-federal.
Watershed management planning studies can be specifically authorized and are cost- shared at 50 percent federal and 50 percent non-federal.
The Corps of Engineers provides emergency response assistance during and following natural disasters. Public Law 84-99 enables the Corps to assist state and local authorities in flood fight activities and cost share in the repair of flood protective structures. Assistance is provided in the flowing categories:
Preparedness—The Flood Control and Coastal Emergency Act establishes an emergency fund for preparedness for emergency response to natural disasters; for flood fighting and rescue operations; for rehabilitation of flood control and hurricane protection structures.
Funding for Corps of Engineers emergency response under this authority is provided by Congress through the annual Energy and Water Development Appropriation Act. Disaster preparedness activities include coordination, planning, training and conduct of response exercises with local, state and federal agencies.
Response Activities—Public Law 84-99 allows the Corps of Engineers to supplement state and local entities in flood fighting urban and other non-agricultural areas under certain conditions (Engineering Regulation 500-1-1 provides specific details). All flood fight efforts require a project cooperation agreement signed by the public sponsor and the sponsor must remove all flood fight material after the flood has receded. Public Law 84-99 also authorizes emergency water support and drought assistance in certain situations and allows for “advance measures” assistance to prevent or reduce flood damage conditions of imminent threat of unusual flooding.
Rehabilitation—Under Public Law 84-99, an eligible flood protection system can be rehabilitated if damaged by a flood event. The flood system would be restored to its pre- disaster status at no cost to the federal system owner, and at 20-percent cost to the eligible non-federal system owner. All systems considered eligible for Public Law 84-99 rehabilitation assistance have to be in the Rehabilitation and Inspection Program prior to the flood event. Acceptable operation and maintenance by the public levee sponsor are verified by levee inspections conducted by the Corps on a regular basis. The Corps has the responsibility to coordinate levee repair issues with interested federal, state, and local agencies following natural disaster events where flood control works are damaged.
These authorities and programs are all available to the planning partners to support any related mitigation actions.
364
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-12
U.S. Bureau of Reclamation Safety Evaluation of Existing Dams Program The U.S. Bureau of Reclamation’s Safety Evaluation of Existing Dams Program was officially implemented in 1978 with passage of the Reclamation Safety of Dams Act (Public Law 95-578). This act was amended in 1984 under Public Law 98-404, in 2000 under Public Law 106-377, in 2002 under Public Law 107-117, and in 2004 under Public Law 108-439. Program development and administration of dam safety activities is the responsibility of the Bureau of Reclamation’s Dam Safety Office located in Denver, Colorado.
Dams must be operated and maintained in a safe manner, ensured through inspections for safety deficiencies, analyses utilizing current technologies and designs, and corrective actions if needed based on current engineering practices. In addition, future evaluations should include assessments of benefits foregone with the loss of a dam. For example, a failed dam can no longer provide needed fish and wildlife benefits.
The primary emphasis of the Safety Evaluation of Existing Dams program is to perform site evaluations and to identify potential safety deficiencies on Bureau of Reclamation and other Interior Department dams. The basic objective is to quickly identify dams which pose an increased threat to the public, and to quickly complete the related analyses in order to expedite corrective action decisions and safeguard the public and associated resources. The selected course of action relies on assessments of risks and liabilities with environmental and public involvement input to the decision-making process.
U.S. Fire Administration
There are federal agencies that provide technical support to fire agencies/organizations. For example, the U.S. Fire Administration, which is a part of FEMA, provides leadership, advocacy, coordination, and support for fire agencies and organizations.
U.S. Fish and Wildlife Service
The U.S. Fish and Wildlife Service fire management strategy uses prescribed fire to maintain early successional fire-adapted grasslands and other ecological communities throughout the National Wildlife Refuge system.
STATE
AB 9: Fire safety: wildfires: fire adapted communities.
Establishes the Regional Forest and Fire Capacity Program to support regional leadership, build local and regional capacity, and develop, prioritize, and implement strategies and projects that create fire- adapted communities by improving watershed health, forest health, community wildfire preparedness, and fire resilience.
AB 32: The California Global Warming Solutions Act
This bill identifies the following potential adverse impacts of global warming:
365
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-13
“… the exacerbation of air quality problems, a reduction in the quality and supply of water to the state from the Sierra snowpack, a rise in sea levels resulting in the displacement of thousands of coastal businesses and residences, damage to marine ecosystems and the natural environment, and an increase in the incidences of infectious diseases, asthma, and other human health-related problems.”
AB 32 establishes a state goal of reducing greenhouse gas emissions to 1990 levels by 2020 (a reduction of approximately 25 percent from forecast emission levels), with further reductions to follow.
The law requires the state Air Resources Board to do the following:
Establish a program to track and report greenhouse gas emissions.
Approve a scoping plan for achieving the maximum technologically feasible and cost-effective reductions from sources of greenhouse gas emissions.
Adopt early reduction measures to begin moving forward.
Adopt, implement, and enforce regulations—including market mechanisms such as “cap and- trade” programs—to ensure that the required reductions occur.
The Air Resources Board has adopted a statewide greenhouse gas emissions limit and an emissions inventory, along with requirements to measure, track, and report greenhouse gas emissions by the industries it determined to be significant sources of greenhouse gas emissions.
AB 38: Fire safety: Low-Cost Retrofits: Regional Capacity Review: Wildfire Mitigation
Requires the seller of any real property located in a high or very fire hazard severity zone to provide a disclosure notice, as specified, to the buyer with information relating to fire hardening improvements on the property.
Requires the California Natural Resources Agency, in consultation with the State Fire Marshal and the Forest Management Task Force, to review the regional capacity of each county that contains a very high fire hazard severity zone to improve forest health, fire resilience, and safety.
Requires the California Office of Emergency Services to enter into a joint powers agreement with the Department of Forestry and Fire Protection to administer a comprehensive wildfire mitigation and assistance program to encourage cost-effective structure hardening and facilitate vegetation management, contingent upon appropriation by the Legislature.
AB 70: Flood Liability
This bill provides that a city or county may be required to contribute a fair and reasonable share to compensate for property damage caused by a flood to the extent that it has increased the state’s exposure to liability for property damage by unreasonably approving new development in a previously undeveloped area that is protected by a state flood control project, unless the city or county meets specified requirements.

AB 162: Flood Planning
This California State Assembly Bill passed in 2007 requires cities and counties to address flood-related matters in the land use, conservation, and safety and housing elements of their general plans. The land use element must identify and annually review the areas covered by the general plan that are subject to flooding as identified in floodplain mapping by either FEMA or the state Department of Water Resources (DWR). During the next revision of the housing element on or after January 1, 2009, the conservation element of the general plan must identify rivers, creeks, streams, flood corridors, riparian habitat, and land that may accommodate floodwater for the purpose of groundwater recharge and stormwater management. The safety element must identify information regarding flood hazards, including:
Flood hazard zones
Maps published by FEMA, DWR, the U.S. Army Corps of Engineers, the Central Valley Flood Protection Board, and the Governor’s Office of Emergency Services (Cal OES) Historical data on flooding
Existing and planned development in flood hazard zones.
The general plan must establish goals, policies and objectives related to flooding risks, including:
Avoiding or minimizing the risks of flooding new development Evaluating whether new development should be located in flood hazard zones Identifying construction methods to minimize damage.
AB 162 establishes goals, policies and objectives related to flooding risks. It establishes procedures for the determination of available land suitable for urban development, which may exclude lands where FEMA or DWR has concluded that the flood management infrastructure is not adequate to avoid the risk of flooding.
AB 267: California Environmental Quality Act: Exemption: Prescribed Fire, Thinning, and Fuel Reduction Projects
Current law, until January 1, 2023, exempts from the requirements of CEQA prescribed fire, thinning, or fuel reduction projects undertaken on federal lands to reduce the risk of high-severity wildfire that have been reviewed under the federal National Environmental Policy Act of 1969. Current law requires the Department of Forestry and Fire Protection, beginning December 31, 2019, and annually thereafter until January 1, 2023, to report to the relevant policy committees of the Legislature the number of times the exemption was used. This extends the exemption from CEQA and the requirement on the department to report to the relevant policy committees of the Legislature to January 1, 2026.
AB 380: Forestry: Priority Fuel Reduction Projects
On March 22, 2019, the Governor issued a proclamation of a state of emergency directing the Department of Forestry and Fire Protection to implement fuel reduction projects for communities at greatest risk of wildfire to reduce the risk of catastrophic wildfire. The proclamation of a state of emergency exempts the identified fuel reduction projects from various legal requirements, including, 367
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-15
among others, requirements regarding public contracting for those projects, requirements for environmental review under the California Environmental Quality Act for those projects, and licensure requirements for individuals conducting certain activities for those projects.
This bill requires the department, before December 31, 2022, and before December 31 of each year thereafter, to identify priority fuel reduction projects, as provided. The bill exempts the identified priority fuel reduction projects from legal requirements in a similar manner as provided in the proclamation of a state of emergency described above.
AB 431: Forestry: Timber Harvesting Plans: Defensible Space: Exemptions The Z’berg-Nejedly Forest Practice Act of 1973 prohibits a person from conducting timber operations, as defined, unless a timber harvesting plan prepared by a registered professional forester has been submitted to, and approved by, the Department of Forestry and Fire Protection. The act authorizes the State Board of Forestry and Fire Protection to exempt from some or all of those provisions of the act a person engaging in specified forest management activities, as prescribed, including, only until January 1, 2022, the cutting or removal of trees on the person’s property in compliance with specified defensible space requirements. This bill extends to January 1, 2026, the board’s authorization to exempt a person engaging in the cutting or removal of trees on the person’s property in compliance with the specified defensible space requirements.
AB 497: Forestry and Fire Protection: Local Assistance Grant Program: Fire Prevention Activities: Street and Road Vegetation Management Under existing law, the Department of Forestry and Fire Protection is required to develop, implement, and administer forest improvement and fire prevention programs in the state. Existing law requires the department to establish a local assistance grant program for fire prevention activities in California.
Existing law requires the department to prioritize, to the extent feasible, projects that are multiyear efforts and to prioritize grant applications from specified local agencies.
This bill appropriated $25,000,000 to provide the local assistance grants. It requires the department to prioritize projects that manage vegetation along streets and roads to prevent the ignition of wildfire and that require the funds for purposes of purchasing equipment necessary for the project.
AB 575: Civil Liability: Prescribed Burning Activities: Gross Negligence This bill provides that a private entity engaging in a prescribed burning activity that is supervised by a person certified as burn boss is liable for damages to a third party only if the prescribed burning activity was carried out in a grossly negligent manner.
AB 642: Wildfires
This omnibus fire prevention bill makes changes to support cultural and prescribed fire, including the creation of a Cultural Burning Liaison at the Department of Forestry and Fire Protection, and requires a proposal for creating a prescribed fire training center in California. The Act requires the Director of Forestry and Fire Protection to identify areas in the state as moderate and high fire hazard severity zones and to classify areas into fire hazard severity zones based on additional factors including 368
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-16
possible lightning caused ignition. The bill requires a local agency, within 30 days of receiving a transmittal from the director that identifies fire hazard severity zones, to make the information available for public comment.
AB 747: Required Information for General Plan Safety Elements This bill requires California communities with general plans to address evacuation routes in the safety element of the general plan. Information on the evacuation routes and their capacity, safety and viability under a range of emergency scenarios must be provided. For communities that have not adopted a local hazard mitigation plan, the safety element must be updated with this information by January 1, 2022. For those with a local hazard mitigation plan, the requirement applies upon the next revision of the hazard mitigation plan on or after January 1, 2022. Communities that have adopted a local hazard mitigation plan, emergency operations plan, or other document that fulfills the goals and objectives of this law may comply with this requirement by summarizing and incorporating by reference the other plan or document in the safety element.
In subsequent revisions to the safety element, communities also will be required to identify new information relating to flood and fire hazards and climate adaptation and resiliency strategies applicable to the city or county that was not available during the previous revision of the safety element. These subsequent updates must occur upon each revision of the general plan housing element or local hazard mitigation plan and not less than once every eight years.
AB 800: Wildfires: Local General Plans: Safety Elements: Fire Hazard Severity Zones
Existing law requires the Director of Forestry and Fire Protection to identify areas of the state as very high fire hazard severity zones, and requires each planning agency to prepare, and the legislative body of each county and city to adopt, a comprehensive, long-term general plan, including a safety element, for the physical development of the county or city. Existing law requires each city or county that contains a very high fire hazard severity zone to submit the draft element of, or draft amendment to the safety element its general plan to the State Board of Forestry and Fire Protection and to every local agency that provides fire protection to territory in the city or county at least 90 days before adoption or amendment.
This requires the director to also identify areas of the state as moderate and high fire hazard severity zones. It requires the draft element of, or draft amendment to, the safety element of a county or city’s general plan to be submitted to the state board and to every local agency that provides fire protection to territory in the city or county at least 90 days before the adoption or amendment to the safety element of its general plan for each city or county that contains a moderate or high fire hazard severity zone.
Existing law requires the state board and authorizes a local agency to review the draft or an existing safety element and recommend changes to the planning agency regarding uses of land and policies in state responsibility areas and very high fire hazard severity zones and regarding methods and strategies for wildland fire risk reduction and prevention within state responsibility areas and very high fire hazard severity zones.
369
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-17
This bill also requires the state board and authorizes a local agency to review the draft or an existing safety element and recommend changes to the planning agency regarding uses of land and policies in moderate and high fire hazard severity zones and regarding methods and strategies for wildland fire risk reduction and prevention within moderate and high fire hazard severity zones.
The existing Subdivision Map Act vests the authority to regulate and control the design and improvement of subdivisions in the legislative body of a local agency, and sets forth procedures governing the local agency’s processing, approval, conditional approval, or disapproval, and filing of tentative, final, and parcel maps, and the modification thereof. The act generally requires a subdivider to file a tentative map or vesting tentative map with the local agency, and requires the local agency to approve, conditionally approve, or disapprove the map within a specified time period. Before approving a tentative map, or a parcel map for which a tentative map was not required, for an area located in a state responsibility area or a very high fire hazard severity zone, existing law requires a legislative body of a county to make specified findings. Existing law requires a legislative body of a county to transmit these findings to the State Board of Forestry and Fire Protection.
This requires a legislative body of a county to make specified findings before approving a tentative map, or a parcel map for which a tentative map was not required, for areas located in moderate and high fire hazard severity zones, and requires these findings to be transmitted to the state board.
By requiring new duties on a county, the bill imposes a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill provides that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to statutory provisions.
AB 1255: Fire Prevention: Fire Risk Reduction Guidance: Local Assistance Grants
This bill requires the Department of Forestry and Fire Protection, in coordination with the Secretary of the Natural Resources Agency, to facilitate regional, habitat-specific, and area-specific approaches to fire risk reduction, prevention, and restoration of projects that improve community safety, protect sites and structures, restore burned habitat, reduce catastrophic wildfires, and protect natural resources. It requires the department to develop policies, funding programs for which the funding shall be contingent upon subsequent appropriation in the annual Budget Act or a similar statute for this purpose, and relevant program guidelines that promote specified objectives. The bill requires various state entities to establish grant programs, for which funding shall be contingent upon subsequent appropriation, to fulfill the specified objectives.
AB 1295: Residential Development Agreements: Very High Fire Risk Areas Current law requires the Director of Forestry and Fire Protection to identify areas in the state as very high fire hazard severity zones based on the severity of fire hazard that is expected to prevail in those areas and requires each local agency to designate, by ordinance, the very high fire hazard severity zones in its jurisdiction. Current law additionally requires the director to classify lands within state responsibility areas into fire hazard severity zones. This bill, prohibits the legislative body of a city or county from entering into a residential development agreement for property in a very high fire risk area. 370
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-18
The bill defines “very high fire risk area” for these purposes to mean a very high fire hazard severity zone designated by a local agency or a fire hazard severity zone classified by the director.
AB 1439: Property Insurance Discounts
This bill requires a residential property insurance policy to include a discount if a local government of the jurisdiction where the insured property is located funds a local wildfire protection or mitigation program. Because the bill mandates discounts for specified residential property insurance policies, thus affecting the Insurance Commissioner’s consideration of a rate, the bill would amend Proposition 103.
AB 1500: Safe Drinking Water, Wildfire Prevention, Drought Preparation, Flood Protection, Extreme Heat Mitigation, and Workforce Development Bond Act of 2022
If approved by the voters, this bill would authorize the issuance of bonds in the amount of $6,700,000,000 pursuant to the State General Obligation Bond Law to finance projects for safe drinking water, wildfire prevention, drought preparation, flood protection, extreme heat mitigation, and workforce development programs.
AB 2140: General Plans—Safety Element
This bill provides that the state may allow for more than 75 percent of public assistance funding under the California Disaster Assistance Act only if the local agency is in a jurisdiction that has adopted a local hazard mitigation plan as part of the safety element of its general plan. The local hazard mitigation plan needs to include elements specified in this legislation. In addition, this bill requires Cal OES to give preference for federal mitigation funding to cities and counties that have adopted local hazard mitigation plans. The intent of the bill is to encourage cities and counties to create and adopt hazard mitigation plans.
AB 2800: Climate Change—Infrastructure Planning
This California State Assembly bill passed in 2016 and until July 1, 2020, requires state agencies to take into account the current and future impacts of climate change when planning, designing, building, operating, maintaining, and investing in state infrastructure. The bill, by July 1, 2017, and until July 1, 2020, requires an agency to establish a Climate-Safe Infrastructure Working Group to examine how to integrate scientific data concerning projected climate change impacts into state infrastructure engineering.
Alquist-Priolo Earthquake Fault Zoning Act
The Alquist-Priolo Earthquake Fault Zoning Act was enacted in 1972 to mitigate the hazard of surface faulting to structures for human occupancy. The Alquist-Priolo Earthquake Fault Zoning Act’s main purpose is to prevent construction of buildings used for human occupancy on the surface trace of active faults. Before a new project is permitted, cities and counties require a geologic investigation to demonstrate that proposed buildings will not be constructed on active faults. The act addresses only the hazard of surface fault rupture and is not directed toward other earthquake hazards, such as 371
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-19
liquefaction or seismically induced landslides. The law requires the State of California Geologist to establish regulatory zones around the surface traces of active faults and to issue appropriate maps.
The maps are distributed to all affected cities, counties, and state agencies for their use in planning and controlling new or renewed construction. Local agencies must regulate most development projects within the zones. Projects include all land divisions and most structures for human occupancy. All seismic hazard mitigation actions identified in this plan will seek full compliance with the Alquist-Priolo Earthquake Fault Zoning Act.
Board of Forestry and Fire Protection Fire Safe Regulations California’s Board of Forestry and Fire Protection is authorized to adopt regulations to implement specified programs. To become effective, the Office of Administrative Law must approve these regulations. Once adopted, Board regulations are placed in Title 14 of the California Code of Regulations. The Department of Forestry and Fire Protection then implements the regulations.
Since 1991, the Board’s Fire Safe Regulations have set the floor for fire safety standards for perimeters and access to all residential, commercial, and industrial building construction in state responsibility areas. They address road standards for fire equipment access, standards for road and building signs, minimum private water supplies for emergency fire use, and fuel breaks and greenbelts. Starting on July 1, 2021, these requirements will also apply in the local responsibility areas and will address construction on ridgelines.
California Coastal Management Program
The California Coastal Management Program under the California Coastal Act requires each city or county lying wholly or partly within the coastal zone to prepare a local coastal plan. The specific contents of such plans are not specified by state law, but they must be certified by the Coastal Commission as consistent with policies of the Coastal Act (Public Resources Code, Division 20). The Coastal Act has provisions relating to geologic hazards, but does not mention tsunamis specifically.
Section 30253(1) of the Coastal Act states that new development shall minimize risks to life and property in areas of high geologic, flood, and fire hazard. Development should be prevented or limited in high hazard areas whenever possible. However, where development cannot be prevented or limited, land use density, building value, and occupancy should be kept at a minimum. Any mitigation project identified in this plan that intersects the mapped coastal zone will be consistent with the recommendations of the local coastal plan.
California Department of Forestry and Fire Protection
CAL FIRE has responsibility for wildfires in areas of the county that are not under the jurisdiction of the Forest Service or a local fire organization, including lands designated as State Responsibility Areas.
CAL FIRE also has fire protection responsibilities by contract and mutual aid agreements. For example, CAL FIRE provides year-round fire protection under Amador Plan agreements with certain local government agencies (Public Resources Code §4144). Through these agreements, CAL FIRE provides local structural and wildfire protection or dispatch services to a community and maintains a staffing level that otherwise would be available only during the fire season. The local entity pays the additional cost of the service.
372
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-20
California Department of Parks and Recreation
State Parks manages portions of the California coastline including coastal wetlands, estuaries, beaches, and dune systems. The State Parks Resources Management Division has limited wildfire protection resources available to suppress fires on State Park lands.
California Department of Water Resources
In California, the DWR is the coordinating agency for floodplain management. The DWR works with FEMA and local governments by providing grants and technical assistance, evaluating community floodplain management programs, reviewing local floodplain ordinances, participating in statewide flood hazard mitigation planning, and facilitating annual statewide workshops. Compliance is monitored by FEMA regional staff and by the DWR.
California Division of Safety of Dams
California’s Division of Safety of Dams (a division of the DWR) monitors the dam safety program at the state level and maintains a working list of dams in the state. When a new dam is proposed, Division engineers and geologists inspect the site and the subsurface. Upon submittal of an application, the Division reviews the plans and specifications prepared by the owner to ensure that the dam is designed to meet minimum requirements and that the design is appropriate for the known geologic conditions.
After approval of the application, the Division inspects all aspects of the construction to ensure that the work is done in accordance with the approved plans and specifications. After construction, the Division inspects each dam to ensure that it is performing as intended and is not developing problems. The Division periodically reviews the stability of dams and their major appurtenances in light of improved design approaches and requirements, as well as new findings regarding earthquake hazards and hydrologic estimates in California. Over 1,200 dams are inspected by Division engineers on a yearly schedule to ensure performance and maintenance of dams.
California Environmental Quality Act
The California Environmental Quality Act (CEQA) was passed in 1970, shortly after the federal government enacted the National Environmental Policy Act, to institute a statewide policy of environmental protection. CEQA requires state and local agencies in California to follow a protocol of analysis and public disclosure of the potential environmental impacts of development projects. CEQA makes environmental protection a mandatory part of every California state and local agency’s decision- making process.
CEQA establishes a statewide environmental policy and mandates actions all state and local agencies must take to advance the policy. Jurisdictions conduct analysis of the project to determine if there are potentially significant environmental impacts, identify mitigation measures, and possible project alternatives by preparing environmental reports for projects that requires CEQA review. This environmental review is required before an agency takes action on any policy, program, or project. Any project action identified in this plan will seek full CEQA compliance upon implementation. 373
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-21
California Fire Alliance
The California Fire Alliance (CFA) was established in response to directives from the 2001 National Fire Plan. The CFA pursues four strategies to deal with the National Fire Plan’s community assistance initiative:
Work with communities at risk from wildfires to develop community-based planning leadership and facilitate the development of community fire loss mitigation plans, which transcend jurisdiction and ownership boundaries.
Assist communities in development of fire loss mitigation planning, education and projects to reduce the threat of wildfire losses on public and private lands.
Develop an information and education outreach plan to increase awareness of wildfire protection program opportunities available to communities at risk.
Work collaboratively to develop, modify and maintain a comprehensive list of communities at risk.
California Fire Plan
The State Board of Forestry and CAL FIRE have prepared a comprehensive update of the California Fire Plan for wildfire protection. The planning process included defining a level of service measurement; considering assets at risk; incorporating the cooperative interdependent relationships of wildfire protection providers; providing for public stakeholder involvement; and creating a fiscal framework for policy analysis. The California Fire Plan’s overall goal is to reduce costs and losses from wildfire in the state by protecting assets at risk through pre-fire management and by reducing the spread of fire through more successful initial response.
California Fire Safe Council
In 1993, the statewide Fire Safe Council, consisting of private and public membership, was formed to educate and encourage Californians to plan and prepare for wildfires by reducing the risk of fire to property, communities, and natural/structural resources. In 2002, this group created a nonprofit organization and board of directors, called the California Fire Safe Council. The Council works with the California Fire Alliance to facilitate the distribution of National Fire Plan grants for wildfire risk reduction and education (www.grants.firesafecouncil.org). The Council also provides assistance to local Fire Safe Councils through its website (www.firesafecouncil.org), the distribution of educational materials, and technical assistance, primarily through regional representatives. More than 130 local Fire Safe Councils have formed in California to plan, coordinate, and implement fire prevention activities.
California Fire Service and Rescue Emergency Mutual Aid Plan The Governor’s Office of Emergency Services Fire and Rescue Branch administers the California Fire Service and Rescue Emergency Mutual Aid Plan. The agency provides guidance and procedures for agencies developing emergency operations plans, as well as training and technical support, primarily to overall emergency service organizations and urban search and rescue teams. 374
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-22
California General Planning Law
California state law requires that every county and city prepare and adopt a comprehensive long-range plan to serve as a guide for community development. The general plan expresses the community’s goals, visions, and policies relative to future land uses, both public and private. The general plan is mandated and prescribed by state law (Cal. Gov. Code §65300 et seq.), and forms the basis for most local government land use decision-making.
The plan must consist of an integrated, internally consistent set of goals, policies, and implementation measures. In addition, the plan must focus on issues of the greatest concern to the community and be written in a clear and concise manner. City and county actions, such as those relating to land use allocations, annexations, zoning, subdivision and design review, redevelopment, and capital improvements, must be consistent with the plan.
California Multi-Hazard Mitigation Plan
Under the DMA, California must adopt a federally approved state multi-hazard mitigation plan to be eligible for certain disaster assistance and mitigation funding. The intent of the State of California Multi- Hazard Mitigation Plan is to reduce or prevent injury and damage from hazards in the state through the following:
Documenting statewide hazard mitigation planning in California Describing strategies and priorities for future mitigation activities Facilitating the integration of local and tribal hazard mitigation planning activities into statewide efforts
Meeting state and federal statutory and regulatory requirements.
The plan is an annex to the State Emergency Plan, and it identifies past and present mitigation activities, current policies and programs, and mitigation strategies for the future. It also establishes hazard mitigation goals and objectives. The plan will be reviewed and updated annually to reflect changing conditions and new information, especially information on local planning activities.
Under 44 CFR Section 201.6, local hazard mitigation plans must be consistent with their state’s hazard mitigation plan. In updating this plan, the Steering Committee reviewed the California State Hazard Mitigation Plan to identify key relevant state plan elements (see Section 3.7).
California Residential Mitigation Program
The California Residential Mitigation Program was established in 2011 to help Californians strengthen their homes against damage from earthquakes. The program is a joint powers authority created by Cal OES and the California Earthquake Authority, which is a not-for-profit, publicly managed, privately funded provider of home earthquake insurance to California homeowners and renters.
Earthquake Brace + Bolt was developed to help homeowners lessen the potential for damage to their houses during an earthquake. A residential seismic retrofit strengthens an existing older house, making it more resistant to earthquake activity such as ground shaking and soil failure. The seismic retrofitting involves bolting the house to its foundation and adding bracing around the perimeter of the crawl space. 375
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-23
Most homeowners hire a contractor to do the retrofit work, and owners of houses in ZIP Codes with house characteristics suitable for this type of retrofit are eligible for up to $3,000 toward the cost. A typical retrofit by a contractor may cost between $3,000 and $7,000, depending on the location and size of the house, contractor fees, and the amount of materials and work involved. If the homeowner is an experienced do-it-yourselfer, a retrofit can cost less than $3,000.
California State Building Code
California Code of Regulations Title 24 (CCR Title 24), also known as the California Building Standards Code, is a compilation of building standards from three sources:
Building standards that have been adopted by state agencies without change from building standards contained in national model codes
Building standards that have been adopted and adapted from the national model code standards to meet California conditions
Building standards authorized by the California legislature that constitute extensive additions not covered by the model codes adopted to address particular California concerns.
The state Building Standards Commission is authorized by California Building Standards Law (Health and Safety Code Sections 18901 through 18949.6) to administer the processes related to the adoption, approval, publication, and implementation of California’s building codes. These building codes serve as the basis for the design and construction of buildings in California. The national model code standards adopted into Title 24 apply to all occupancies in California, except for modifications adopted by state agencies and local governing bodies. Since 1989, the Building Standards Commission has published new editions of Title 24 every three years.
On January 1, 2014, California Building Code Accessibility Standards found in Chapter 11B incorporated the 2010 Americans with Disabilities Act (ADA) Standards as the model accessibility code for California. The purpose was to ensure consistency with federal guidelines. As a result of this incorporation, the California standards will fully implement and include 2010 ADA Standards within the California Building Code while maintaining enhanced levels of accessibility already provided by existing California accessibility regulations.
Disadvantaged and Low-income Communities Investments
Senate Bill (SB) 535 directs state and local agencies to make investments that benefit California’s disadvantaged communities. It also directs the California Environmental Protection Agency to identify disadvantaged communities for the purposes of these investments based on geographic, socio- economic, public health, and environmental hazard criteria. Assembly Bill (AB) 1550 increased the percent of funds for projects located in disadvantaged communities from 10 to 25 percent and added a focus on investments in low-income communities and households. This program is a potential alternative source of funding for actions identified in this plan.
Division of the State Architect’s AB 300 List of Seismically At-Risk Schools In 2002, California’s Division of the State Architect completed an inventory of public school buildings built before 1978 that identifies buildings with characteristics that might make them unsafe in future 376
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-24
earthquakes. This inventory provides a list of potentially at-risk schools known as the AB 300 list (the inventory was authorized by Assembly Bill 300 in 1999). Using available information on school buildings’ dates of construction, seismic retrofits, and structural systems (wood-frame, concrete shear wall, or steel moment frame, etc.), the inventory categorized California public school buildings into one of two categories: those expected to perform well in future earthquakes; and those that are not expected to perform well and require more detailed seismic evaluation.
The Division of the State Architect recommends that public schools on this list undergo detailed seismic evaluations to determine if they pose life safety risks, but the state has neither required nor funded school districts to do this.
Governor’s Executive Order S-13-08
Governor’s Executive Order S-13-08 enhances the state’s management of climate impacts from sea- level rise, increased temperatures, shifting precipitation and extreme weather events. There are four key actions in the executive order:
Initiate California’s first statewide climate change adaptation strategy to assess expected climate change impacts, identify where California is most vulnerable, and recommend adaptation policies. This effort will improve coordination within state government so that better planning can more effectively address climate impacts on human health, the environment, the state’s water supply and the economy.
Request that the National Academy of Science establish an expert panel to report on sea-level rise impacts in California, to inform state planning and development efforts.
Issue interim guidance to state agencies for how to plan for sea-level rise in designated coastal and floodplain areas for new projects.
Initiate a report on critical infrastructure projects vulnerable to sea-level rise.
Office of the State Fire Marshal
The Office of the State Fire Marshal is a division of CAL FIRE that has a wide variety of fire safety and training responsibilities and provides technical support to fire agencies/organizations.
Senate Bill 12: Local Government: Planning and Zoning: Wildfires This bill imposes new planning requirements on local governments, as follows:
Defines “very high fire risk areas” to be the VHFHSZ in both the SRA and the Local Responsibility Area.
Requires each city or county, upon the next revision of the housing element or local hazard mitigation plan on or after July 1, 2024, whichever occurs first, to review and update its safety element to include a comprehensive retrofit strategy that includes specified contents.
Requires a city or county with VHFHSZ within its jurisdiction to amend the land use element of its general plan upon the next revision of the housing element on or after July 1, 2024. This amendment of the land use element must include the locations of all VHFHSZ within the city or county, the data and analysis described in the Office of Planning and Research’s publication 377
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-25
Fire Hazard Planning–General Plan Technical Advice Series, and other specified goals, objectives, and implementation measures.
Requires, after the initial amendment to the land use element, that a city or county review upon each revision of the housing element the implementation of the wildfire risk reduction standards within the jurisdiction and the designation of VHFHSZ.
Provides for review and comment on draft findings by the Board and local fire agencies on whether the city or county has implemented the standards or made adequate progress, as defined.
Requires, on or before January 1, 2023, to develop and post on its web site a clearinghouse of local ordinances, policies, and best practices relating to land use planning in VHFHSZ, wildfire risk reduction, and wildfire preparedness. The Office of Planning and Research must also regularly update the clearinghouse.
Senate Bill 92: Public Resources Portion of Biennial Budget Bill The State of California updated its requirements regarding emergency action plans (EAPs) via Senate Bill 92, which became effective in June 2017 as part of the state Legislature’s biennial budget process.
The bill required dam owners to submit EAPs to Cal OES and the Department of Water Resources for approval by January 1, 2018 (for extremely high hazard dams), January 1, 2019 (for high-hazard dams), and January 1, 2021 (for significant hazard dams). The EAPs were to include the following (California Government Code Section 8589.5):
Emergency notification flow charts
Information on a four-step response process
Description of agencies’ roles and actions in response to an emergency incident Description of actions to be taken in advance of an emergency Inundation maps
Additional information such as revision records and distribution lists.
After the EAPs are approved by the state, the law requires dam owners to send the approved EAPs to relevant stakeholders. Local public agencies can then adopt emergency procedures that incorporate the information in the EAP in a manner that conforms to local needs and includes methods and procedures for alerting and warning the public and other response and preparedness related items.
SB 92 also requires dams other than low-risk dams to have current inundation mapping, which must be updated every 10 years, or sooner if specific circumstances change. EAPs also must be updated every 10 years. It provides DWR with enforcement tools, including fines and operational restrictions for failure to comply. Cal OES is required by the law to work with state and federal agencies, dam owners, planners, and the public to make dam failure inundation maps available to citizens interested in learning their dam failure inundation risk.
Senate Bill 97: Guidelines for Greenhouse Gas Emissions Senate Bill 97, enacted in 2007, amends CEQA to clearly establish that greenhouse gas emissions and the effects of greenhouse gas emissions are appropriate subjects for CEQA analysis. It directs the 378
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-26
Governor’s Office of Planning and Research to develop draft CEQA guidelines for the mitigation of greenhouse gas emissions or their effects by July 1, 2009 and directs the California Natural Resources Agency to certify and adopt the CEQA Guidelines by January 1, 2010.
Senate Bill 99: Evacuation Route Planning
Senate Bill 99, enacted in 2019, requires that cities’ and counties’ general plans address evacuation routes from any hazard area identified in the safety element. Under this law, the safety element must include information to identify residential developments in hazard areas that do not have at least two emergency evacuation routes. Each city or county must update its safety element with the new information upon the next revision of its housing element on or after January 1, 2020.
Senate Bill 182 Local Government: Planning and Zoning: Wildfires California Senate Bill 182 made a number of changes to state law regarding planning for and permitting development in areas designated as very high fire risk areas. The bill requires a local jurisdiction to do the following:
Include a comprehensive retrofit strategy in its safety element to reduce the risk of property loss and damage during wildfires.
Amend its land use element to identify all very high fire risk areas and to establish measures to protect lives and property from unreasonable risk of wildfire.
Adopt a very high fire risk overlay zone for its zoning ordinance.
Allocate a lower portion of projected future housing to very high fire hazard severity zones This bill prohibits local governments from entering into a development agreement for property in a very high fire risk area, approving a permit for a project in a very high fire risk area, or approving a tentative map for a subdivision in a very high fire risk area, unless the jurisdiction makes specified findings based on substantial evidence.
Senate Bill 379: General Plans: Safety Element—Climate Adaptation Senate Bill 379 builds upon the flood planning inclusions into the safety and housing elements and the hazard mitigation planning safety element inclusions in general plans outlined in AB 162 and AB 2140, respectively. SB 379 focuses on a new requirement that cities and counties include climate adaptation and resiliency strategies in the safety element of their general plans beginning January 1, 2017. In addition, this bill requires general plans to include a set of goals, policies and objectives, and specified implementation measures based on the conclusions drawn from climate adaptation research and recommendations.
Senate Bill 1000: General Plan Amendments—Safety and Environmental Justice Elements
In 2016, Senate Bill 1000 amended California’s Planning and Zoning Law in two ways:
The original law established requirements for initial revisions of general plan safety elements to address flooding, fire, and climate adaptation and resilience. It also required subsequent review 379
Ventura County Multi-Jurisdictional Hazard Mitigation Plan B. Federal and State Agencies, Programs and Regulations B-27
and revision as necessary based on new information. Senate Bill 1000 specifies that the subsequent reviews and revision based on new information are required to address only flooding and fires (not climate adaptation and resilience).
Senate Bill 1000 adds a requirement that, upon adoption or revision of any two other general plan elements on or after January 1, 2018, an environmental justice element be adopted for the general plan or environmental justice goals, policies and objectives be incorporated into other elements of the plan.
Senate Bill 1035: Fire, Flood, and Adaptation Safety Element Updates Senate Bill 1035 clarifies that revisions to a community’s General Plan Safety Element—to address fire hazards, flood hazards, and climate adaptation and resilience strategies—must occur upon each revision to a Housing Element or Local Hazard Mitigation Program.
Senate Bill 1241: General Plans: Safety Element—Fire Hazard Impacts In 2012, Senate Bill 1241 passed requiring that the safety elements of all future general plans address fire risk in state responsibility areas and very high fire hazard severity zones. The bill requires cities and counties to make findings regarding available fire protection and suppression services before approving a tentative map or parcel map.
Standardized Emergency Management System
CCR Title 19 establishes the Standardized Emergency Management System (SEMS) to standardize the response to emergencies involving multiple jurisdictions. SEMS is intended to be flexible and adaptable to the needs of all emergency responders in California. It requires emergency response agencies to use basic principles and components of emergency management. Local governments must use SEMS by December 1, 1996, to be eligible for state funding of response-related personnel costs under CCR Title 19 (Sections 2920, 2925 and 2930). The roles and responsibilities of Individual agencies contained in existing laws or the state emergency plan are not superseded by these regulations. This hazard mitigation plan is considered to be a support document for all phases of emergency management, including those associated with SEMS.
Western Governors Association Ten-Year Comprehensive Strategy The Western Governors Association Ten-Year Comprehensive Strategy: A Collaborative Approach for Reducing Wildfire Risks to Communities and the Environment (August 2001) is strategy implementation plan prepared by federal and Western state agencies that outlines measures to restore fire-adapted ecosystems and reduce hazardous fuels.

DAM FAILURE INUNDATION MAPPING
Dam breach inundation maps, including inundation boundaries and depth grids, were downloaded from the California Department of Water Resources’ (DWR) website (https://fmds.water.ca.gov/maps/damim/). As required by California Water Code section 6161, the Division of Safety of Dams (DSOD) at DWR reviews and approves inundation maps prepared by licensed civil engineers and submitted by dam owners for extremely high, high, and significant hazard dams and their critical appurtenant structures.

EARTHQUAKE MAPPING
Liquefaction Zones
Seismic Hazard Zone Maps for Liquefaction dataset downloaded from the California Geological Survey’s geologic hazards data website (https://maps.conservation.ca.gov/geologichazards/). The seismic hazards zones datasets include areas where liquefaction may occur during a strong earthquake. Developers of properties falling within the zones may be required to investigate the potential hazard and mitigate its threat during the local permitting process. The data is used by cities and counties to regulate development and by property owners selling property within areas where seismic hazard zones have been identified. Local governments can withhold development permits until geologic or soils investigations are conducted for specific sites and mitigation measures are incorporated into development plans. Sellers of property use the data to check the location of their specific site and, if applicable, disclose to the buyer that the property lies within a seismic hazard zone as required by the Seismic Hazards Mapping Act of 1990 (Public Resources Code, Division 2, Chapter
7.8). This data may not show all areas that have potential for liquefaction. Also, a single earthquake capable of causing liquefaction will not uniformly affect the entire zone. The identification and location of liquefaction zones are based on the best available data. However, the quality of data used is varied.
Zone boundaries have been drawn as accurately as possible at the map scale (1:24,000). 385
Ventura County Multi-Jurisdictional Hazard Mitigation Plan C. Mapping Methods & Data Sources C-3
National Earthquake Hazard Reduction Program (NEHRP) Soils NEHRP soils information is derived from a shear wave velocity (Vs30) data produced by the California Geological Survey in 2015. The Vs30 data represents simplified geologic units that have been correlated to the time-averaged shear-wave velocity in the upper 30 meters of the earth’s surface. The geologic units were compiled from published maps that range in scale from 1:250,000 to 1:24,000. (Wills, et al., 2015)
Probabilistic Peak Ground Acceleration Maps
Probabilistic peak ground acceleration data, by Census tract, are generated by Hazus 4.2 SP03. In Hazus’ probabilistic analysis procedure, the ground shaking demand is characterized by spectral contour maps developed by the U.S. Geological Survey (USGS) as part of a 2018 update of the National Seismic Hazard Maps. USGS probabilistic seismic hazard maps are revised about every six years to reflect newly published or thoroughly reviewed earthquake science and to keep pace with regular updates of the building code. Hazus includes maps for eight probabilistic hazard levels: ranging from ground shaking with a 39 percent probability of being exceeded in 50 years (100-year return period) to the ground shaking with a 2 percent probability of being exceeded in 50 years (2,500-year return period).
Shake Maps
A shake map is designed as a rapid response tool to portray the extent and variation of ground shaking throughout the affected region immediately following significant earthquakes. Ground motion and intensity maps are derived from peak ground motion amplitudes recorded on seismic sensors (accelerometers), with interpolation based on estimated amplitudes where data are lacking, and site amplification corrections. Color-coded instrumental intensity maps are derived from empirical relations between peak ground motions and Modified Mercalli intensity. For this plan, shake maps were prepared by the USGS for four earthquake scenarios:
An earthquake on the Oak Ridge (Onshore) fault with the following characteristics:
Magnitude: 7.16
Epicenter: N 34.31 W 118.96
Depth: 12.8 km
An earthquake on the San Cayetano fault with the following characteristics:
Magnitude: 7.16
Epicenter: N 34.54 W 118.95
Depth: 10.2 km
An earthquake on the S. San Andreas fault with the following characteristics:
Magnitude: 8.03
Epicenter: N 34.80 W 118.85
Depth: 9.1 km
An earthquake on the Ventura-Pitas Point fault with the following characteristics:
Magnitude: 7.12
Epicenter: N 34.32 W 119.28
386
Ventura County Multi-Jurisdictional Hazard Mitigation Plan C. Mapping Methods & Data Sources C-4
Depth: 10.0 km
FLOOD MAPPING
Flood hazard areas are from the countywide effective FEMA Digital Flood Insurance Rate Map (DFIRM) dated January 29, 2021 with the latest incorporated Letter of Map Revision (LOMR) dated June 18, 2021.
LANDSLIDE MAPPING
Susceptibility to Deep-Seated Landslidesdata provided by the California Geological Survey. The map, and associated data, show the relative likelihood of deep-seated landsliding based on regional estimates of rock strength and steepness of slopes. On the most basic level, weak rocks and steep slopes are most likely to generate landslides. The map uses detailed information on the location of past landslides, the location and relative strength of rock units, and steepness of slope to estimate susceptibility to deep-seated landsliding (0 to X, low to high). The USGS 2009 National Elevation Dataset (NED) with 10-m grid size was used as the base map. This landslide susceptibility map is intended to provide infrastructure owners, emergency planners and the public with a general overview of where landslides are more likely to occur. (Wills, et al., 2011)
SEA-LEVEL RISE MAPPING
Projected sea level rise data are from the USGS Coastal Storm Modeling System (CoSMoS), accessed via the Our Coast Our Future web platform (Point Blue Conservation Science and USGS). The projections were generated using the latest downscaled climate projections and calibrated hydrodynamic models by the CoSMoS project team led by Patrick Barnard, at the USGS Pacific Coastal and Marine Science Center.
TSUNAMI MAPPING
Initial tsunami modeling was performed by the University of Southern California Tsunami Research Center funded through the California Emergency Management Agency by the National Tsunami Hazard Mitigation Program. The tsunami modeling process utilized the MOST (Method of Splitting Tsunamis) computational program (Version 0), which allows for wave evolution over a variable bathymetry and topography used for the inundation mapping (Titov and Gonzalez, 1997; Titov and Synolakis, 1998).
The bathymetric/topographic data that were used in the tsunami models consist of a series of nested grids. Near-shore grids with a 3 arc-second (75- to 90-meters) resolution or higher were adjusted to “mean high water” sea-level conditions, representing a conservative sea level for the intended use of the tsunami modeling and mapping. A suite of tsunami source events was selected for modeling, representing realistic local and distant earthquakes and hypothetical extreme undersea, near-shore landslides. Local tsunami sources that were considered include offshore reverse-thrust faults, restraining bends on strike-slip fault zones and large submarine landslides capable of significant seafloor displacement and tsunami generation. Distant tsunami sources that were considered include great subduction zone events that are known to have occurred historically (1960 Chile and 1964 Alaska earthquakes) and others that can occur around the Pacific Ocean “Ring of Fire.” 387
Ventura County Multi-Jurisdictional Hazard Mitigation Plan C. Mapping Methods & Data Sources C-5
In order to enhance the result from the 75- to 90-meter inundation grid data, a method was developed utilizing higher-resolution digital topographic data (3- to 10-meters resolution) that better defines the location of the maximum inundation line. The location of the enhanced inundation line was determined by using digital imagery and terrain data on a GIS platform with consideration given to historical inundation information (Lander, et al., 1993). This information was verified, where possible, by field work coordinated with local county personnel.
The accuracy of the inundation line shown on these maps is subject to limitations in the accuracy and completeness of available terrain and tsunami source information, and the current understanding of tsunami generation and propagation phenomena as expressed in the models. Thus, although an attempt has been made to identify a credible upper bound to inundation at any location along the coastline, it remains possible that actual inundation could be greater in a major tsunami event. This map does not represent inundation from a single scenario event. It was created by combining inundation results for an ensemble of source events affecting a given region. For this reason, all of the inundation region in a particular area will not likely be inundated during a single tsunami event. (State of California, 2009)
WILDFIRE MAPPING
PRC 4201 – 4204 and Govt. Code 51175-89 directed the California Department of Forestry and Fire Protection, Fire and Resource Assessment Program (CALFIRE - FRAP) to map areas of significant fire hazards based on fuels, terrain, weather, and other relevant factors. These zones, referred to as Fire Hazard Severity Zones (FHSZ), define the application of various mitigation strategies to reduce risk associated with wildland fires. CAL FIRE remapped Fire Hazard Severity Zones (FHSZ) for State Responsibility Areas (SRA) and Very High Fire Hazard Severity Zones (VHFHSZ) recommendations in Local Responsibility Areas (LRA) in 2005 – 2008 to provide updated map zones, based on new data, science, and technology.
Mapping of the areas referred to as Very High Fire Hazard Severity Zones (VHFHSZ) was based on data and models of potential fuels over a 30- to 50-year time horizon and their associated expected fire behavior, and expected burn probabilities to quantify the likelihood and nature of vegetation fire exposure (including firebrands) to buildings. The goal of the mapping effort was to create more accurate fire hazard zone designations such that mitigation strategies would be implemented in areas where hazards warrant these investments. The fire hazard zones provide specific designation for application of defensible space and building standards consistent with known mechanisms of fire risk to people, property, and natural resources.

INTRODUCTION
BACKGROUND
Ventura County’s hazard mitigation plan was developed and adopted in 2005 as a multi-jurisdictional process. Subsequent updates conducted in both 2010 and 2015 were also multi-jurisdictional efforts.
Multi-jurisdictional hazard mitigation planning can be an effective process to build partnerships between communities that face common hazard risks, leading to shared solutions. It can also help build a foundation to shift priorities as risks and vulnerabilities change. Multi-jurisdictional planning processes are encouraged by the Federal Emergency Management Agency (FEMA), and offer the following advantages:
Improves communication and coordination among jurisdictions and other regional entities Enables comprehensive mitigation approaches to reduce risks that affect multiple jurisdictions Maximizes economies of scale by leveraging individual capabilities and sharing costs and resources
Avoids duplication of efforts, and
Provides an organizational structure that local jurisdictions may find supportive.
For theVentura County Multi-Jurisdictional Hazard Mitigation Plan 2022 update, a planning partnership was formed that expanded the partnership established during the 2015 hazard mitigation plan update, leveraging resources and meeting 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 to the County, the jurisdictions participating in theMulti-Jurisdictional Hazard Mitigation Plan 2022 update include:
10 incorporated municipalities
14 special districts
All participating jurisdictions in a multi-jurisdictional plan must meet the requirements of Chapter 44 of the Code of Federal Regulations (44 CFR):
508
Ventura County Multi-Jurisdictional Hazard Mitigation Plan xvi
“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)).
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 Commitment
A planning team made up of Ventura County staff solicited the participation of eligible municipalities and special districts in June 2019, at the outset of this update effort. Emails were sent to the applicable points of contact for the 18 members of the 2015 plan and to additional interested parties. Local governments wishing to join the planning effort were asked to provide the California Office of Emergency Services and County with a “letter of commitment” as a participating jurisdiction in the County’s plan update process. In all, the planning team received formal commitment from 24 planning partners in addition to the County.

Introduction

Planning Partner Expectations
The planning team and consultant, Tetra Tech, developed the following list of planning partner expectations, which were provided and discussed at a formal kickoff meeting held in May 2021 (see Appendix A for details):
Re-confirm lead and primary points of contact for the update effort.
Support and participate in the Steering Committee meetings.
Provide support required to implement the public involvement strategy.
Participate in the planning process through:
Steering Committee meetings
Public meetings and outreach efforts
Workshops and planning partner-specific training sessions Public review and comment periods prior to adoption.
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.
Attend the mandatory Phase 3 jurisdictional annex workshop.
Review and determine if the mitigation recommendations chosen in Volume 1 will meet the needs of the jurisdiction.
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 the hazard mitigation plan, each planning partner also agrees to the plan implementation and maintenance protocol established in Volume 1. Failure to meet these criteria would result in a partner being dropped from the partnership by the Steering Committee, and thus losing eligibility under the scope of the plan. All planning partners met the planning partner expectations, including attendance at mandatory workshops.
Final Coverage
All of the above jurisdictions submitted letters of commitment to participate, completed an annex template, fully met the participation requirements for this update, and will be covered by the updated hazard mitigation plan upon FEMA’s approval of the plan and adoption of the plan by their individual governing bodies.
ANNEX DEVELOPMENT
Capability Assessment
A capability assessment creates an inventory of a jurisdiction’s mission, programs, and policies, and evaluates its capacity to carry them out. All participating jurisdictions compiled a capability assessment which helped to identify potential gaps in the jurisdictions’ capabilities. Specifically, if the capability 510
Ventura County Multi-Jurisdictional Hazard Mitigation Plan xviii
assessment identified an opportunity to add a missing core capability or expand an existing one, then doing so has been selected as an action in the jurisdiction’s action plan. The sections below describe 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 counties and municipalities is generally broader than that of special-purpose districts, the assessment of these capabilities is more detailed for those partners.
Development and Permitting Capability
The County and its municipalities 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 mitigate hazards. As special-purpose districts typically do not have the ability to regulate land use, this capability was assessed only for the County and municipalities.
Fiscal Capability
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 (fees charged to a development project).
Administrative and Technical Capability
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, scientists, and grant writers.
Education and Outreach Capability
Regular engagement with the public on hazard mitigation provides opportunities to open a two-way dialogue that can result in a more resilient community. Use of a jurisdictional website, social media outlets, and other outreach resources to communicate mitigation information are assessed for each planning partner. Assessing outreach and education capability illustrates the connection between the government and community members.
Compliance with National Flood Insurance Program Requirements Flooding is the costliest natural hazard in the United States and homeowners face increasingly high flood insurance premiums. Community participation in the National Flood Insurance Program (NFIP) opens up opportunities for additional grant funding associated specifically with flooding issues.
Assessment of a jurisdiction’s current NFIP status and compliance provides a greater understanding of 511
Introduction
xix
the local flood management program, opportunities for improvement, and available grant funding opportunities. The NFIP is not available to special-purpose districts, so this set of capabilities was assessed only for municipalities and the County.
Participation in Voluntary Programs
Participation in voluntary programs, such as FEMA’s Community Rating System (CRS), the National Weather Service’s StormReady and TsunamiReady programs, and the National Fire Protection Association’s Firewise USA, can enhance a jurisdiction’s ability to mitigate, prepare for, and respond to natural hazards. 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. Participation in these programs demonstrates a jurisdiction’s commitment to go beyond the minimum requirements set forth by local, state, and federal regulations in order to create a more resilient community. The programs reviewed here are only applicable to municipalities and the County, so were not included in the capability assessments for the special-purpose districts.
Adaptive Capacity
An adaptive capacity assessment evaluates a jurisdiction’s ability to anticipate impacts that may occur in the future. By looking at public support, technical adaptive capacity, and other factors, jurisdictions can identify their core capability for resilience against issues such as sea level rise and climate change.
The assessment provides jurisdictions with an opportunity to identify areas for improvement by ranking their adaptive capacity as high, medium, or low.
Mitigation Action Plan Development
Risk Ranking
The risk-ranking methodology for partner annexes was the same as that used for the countywide risk ranking described in Volume 1. Each planning partner was asked to review the ranked risk for its jurisdiction, based on the impact on its population and/or facilities. Municipalities and the County based this ranking on the probability of occurrence of each hazard, and its 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, vital facilities, and the facilities’ functionality after a hazard event.
The objectives of this exercise were to familiarize the planning partnership with how to use the risk ranking, part of the assessment results, 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 were considered to be priorities for identifying mitigation actions, although jurisdictions also identified actions to mitigate hazards ranked “low”, as appropriate.
Information Reviewed to Develop the Action Plan
In September 2021, each planning partner was provided with a tool kit of relevant documents to assist in developing their jurisdiction’s action plan and was required to attend a workshop that provided 512
Ventura County Multi-Jurisdictional Hazard Mitigation Plan xx
guidance to develop their action plans. The tool kits were used during the mandatory Phase 3 workshops and in follow-up work conducted by the planning partners. Planning partners reviewed the following information included in the tool kit to assist in the identification of proposed mitigation actions:
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.
National Flood Insurance Program compliance table—Reviewed to identify opportunities to increase floodplain management capabilities.
Adaptive capacity—Reviewed to identify ways to leverage or continue to improve existing capacities and to improve understanding of other capacities.
Future integration opportunities—Reviewed to identify specific integration actions to be included in the mitigation strategy.
Jurisdiction-specific vulnerabilities—Reviewed to identify actions that could reduce known vulnerabilities.
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 mitigation actions recommended in each jurisdiction’s 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 grant 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 benefit-cost analysis and the assignment of the two priority ratings.
Benefit/Cost Review
Pursuant to 44 CFR, Section 201.6(c)(3)(iii), the action plan must be prioritized according to a benefit- cost analysis (BCA) of the proposed actions. BCA is a method that determines the future risk reduction benefits of a hazard mitigation project and compares those benefits to its costs. For this hazard mitigation plan, a qualitative review was performed for each mitigation action by assigning ratings for benefit and cost as follows:
513
Introduction
xxi
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.
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. It is important to note that this qualitative review is not intended to substitute for the more detailed level of benefit-cost analysis required for some FEMA hazard-related grant programs.
More specific analysis would be performed at the time a given action is submitted for grant funding approval.
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, but 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.
514
Ventura County Multi-Jurisdictional Hazard Mitigation Plan xxii
Low Priority—An action that has not been identified as meeting any grant eligibility requirements.
Classification of Actions
Each recommended action was also 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 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 effects.
Community Capacity Building—Actions that increase or enhance local capabilities to adjust to potential damage, to take advantage of opportunities to build capacity, or to respond to consequences of insufficient capacity. Includes staff training, memorandums of understanding, development of plans and studies, and monitoring programs.

Templates were created for the two types of jurisdictions (municipalities and special districts) participating in this plan to help the planning partners prepare their jurisdiction-specific annexes. The templates were designed 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. The templates were deployed in three phases during the course of the plan update process as follows:

Workshop
All partners were required to attend and participate in a virtual technical assistance workshop held the week of September 20, 2021, where key elements of the annex template were discussed. The workshops focused on how the tool kit could be used to facilitate completion of the template and develop each jurisdiction’s mitigation action plan. The templates were subsequently completed by a designated point of contact for each partner and a member of the planning team. The workshop addressed the following topics:
The jurisdictional annex templates and the tool kit
Natural events history
Jurisdiction-specific issues
Risk ranking
Status of prior actions
Developing the action plan
Benefit-cost review
Prioritization protocol
Next steps
Following conclusion of the workshop, a copy of the presentation given at the workshop session was added to the tool kit provided to each of the planning partners. 517

1.2 JURISDICTION PROFILE
1.2.1 Location and Features
Ventura County is located on southern California’s Pacific coast, approximately 60 miles northwest of Los Angeles. The County is bordered to the north by Kern County; to the northwest and southwest by 520
Ventura County Multi-Jurisdictional Hazard Mitigation Plan 1-2
Santa Barbara County and the Pacific Ocean, respectively; and to the east and southeast by Los Angeles County.
Ventura County stretches across 2,208 square miles, of which 1,845 square miles is land and 363 square miles is water. The northern half of the county, comprising approximately 53 percent of the county’s total area is located within the Los Padres National Forest, and is mostly uninhabited. Two offshore islands, Anacapa and San Nicolas, are also included within the jurisdictional boundary for Ventura County. Anacapa Island is located approximately 11 miles offshore and is one of five islands that make up Channel Islands National Park. San Nicolas Island is located approximately 61 miles offshore and is operated by the United States Navy as a weapons testing and training facility. For the purposes of statistical analyses, the county is divided into 15 distinct planning areas. Within the County there are 10 cities and 18 unincorporated communities that are recognized census designated places (CDPs).
1.2.2 History
Ventura County was historically inhabited by the Chumash people, who also settled throughout much of Santa Barbara and San Luis Obispo Counties. The Chumash were originally hunters and gatherers, fisherman, traders, and are known for their rock paintings and basketry.
Spanish explorers began arriving in the area in the mid-1500s, although active occupation did not effectively occur until more than 200 years later. The Spanish encouraged settlement of the area with large land grants called ranchos, while the Catholic church established the Mission San Buenaventura in 1782 in what is now the City of Ventura.
On January 1, 1873, just 23 years after California’s statehood was attained in 1850, Ventura County was formally established. At this time, however, the area remained largely rural, consisting of a population of less than 5,000 individuals that engaged predominately in ranching and the cultivation of grain crops.
During the early 1900s, increased demand from new markets in the burgeoning Los Angeles area led to a significant expansion and diversification of agriculture in Ventura. Together with the discovery of vast oil reserves in the area, this resulted in an influx of immigrants, wealth, and substantial improvements to transportation infrastructure in the region.
A second, intense population boom (>5% annually) occurred beginning in the 1940s with the construction of Port Hueneme and the establishment of a military base at Point Mugu which brought numerous professionals and ancillary industries to the region. Ventura County, and the Oxnard area in particular, benefitted from the hiring of more than 10,000 civilian workers and 21,000 military personnel, thus providing jobs for local residents and reviving the economy following the Depression of the 1930s.
By 1950, the population of the county had increased to over 114,000 individuals, more than double its population in 1930.
The population continued to grow rapidly through the 1970s, assisted further by the completion of highway 101 in the mid-1964, which helped make the commute to Los Angeles easier. Although much of this growth was centered in incorporated communities, development also expanded in the unincorporated areas, particularly on the east side of the County. 521

1.2.3 Governing Body Format
Ventura County is administered by five elected supervisors who each serve four-year terms. The supervisors appoint department administrators who manage county functions.
The Board of Supervisors assumes responsibility for the adoption of this plan; Ventura County Sheriff’s Office of Emergency Services will oversee its implementation.
1.3 CURRENT TRENDS
1.3.1 Population
According to the California Department of Finance, as of January 2020 the unincorporated areas of the County had a population of 95,001. This represents a negligible increase from the 2010 census data (94,937 individuals).
Table 1-2 lists unincorporated communities in Ventura County that are recognized by the United States Census Bureau as census-designated places for the 2020 census:

The bulk of the population within the unincorporated county area is concentrated within four of these communities. Approximately 17,000 people reside in the adjoining communities of Oak View, Meiners Oaks and Mira Monte on the west end of the county. Meanwhile, nearly 14,000 people reside in the community of Oak Park on the east end of the county.
1.3.2 Development
Unincorporated Ventura County is a slow-growth, mostly rural land use jurisdiction with policies and initiatives that seek to focus growth and development in more urbanized areas. Developed areas include about 18 existing census-designated places listed in the previous section, most of which are 522
Ventura County Multi-Jurisdictional Hazard Mitigation Plan 1-4
governed by one of nine specific area plans. For the period between 2016-2020, single-family residences made up approximately half of the development activity in the unincorporated areas, while accessory dwelling units comprised an additional 35 percent of the development activity. Agricultural worker housing projects represented approximately 1 percent of development activity, while other multi- family projects and subdivisions were uncommon, representing less than 7 percent of the development in the unincorporated areas. Permits for commercial development constituted 9 percent of the development activity. For a more detailed description of development trends, see the 2020 Annual Progress Report available here:
https://vcrma.org/docs/images/pdf/planning/plans/2020_Ventura_County_Annual_Progress_Report.pdf Table 1-3 summarizes development trends in the unincorporated County in the period since the preparation of the previous (2015) Hazard Mitigation Plan update, as well as expected future development trends.
Table 1-3.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 theestimated area
annexed and estimated
number of parcels or
structures.
Is your jurisdiction expected to
annex any areas during the
performance period of this plan?
No
If yes, describe land areas and

these areas?
Provide the number of new
construction permits for each
hazard area or provide a
qualitative description of where
development has occurred.
Permitting activity in 2020 was concentrated in the areas around Piru, Oak View, and Meiners Oaks.
In particular, within the Piru area, the buildout of the Piru Gateway development (Tract Map 5553, recorded in 2017) has been under construction for the past several years. This development consists of 53 single-family homes, 4 duplex units, and 10 triplex units, for a total of 91 new residential units. Conversely, in the Oak View and Meiners Oaks areas, most new development consisted of legalization of existing, unpermitted accessory units, and construction of new accessory dwelling units. Much of this development is being driven by state-level regulation changes that went into effect on January 1, 2020 which limit local agency authority to regulate accessory dwelling units.
Much of the development is located in high fire hazard severity zones, including Piru, the Oak View and Meiners Oaks areas near Ojai, the hills north of Camarillo, and southeast of Simi Valley in Bell Canyon.
A small number of single-family permits have also been issued in coastal areas that are primarily for redevelopment of existing structures. Most of these coastal structures are vulnerable to tsunami and other coastal hazards.

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
In February 2021, the County approved a 360-unit farmworker housing project north of the city of Camarillo called “Somis Ranch”, which will be constructed in three phases over the next few years.
Five hundred, ninety-eight additional units are also planned to be constructed over the next four years as part of the continued development (Phase II) of the University Glenn area located adjacent to California State University Channel Islands. This master-planned, mixed-use residential community is proposed to be located on 32 acres south of the City of Camarillo, along the western edge of the Santa Monica Mountains, within a high-fire hazard area. Additional housing is also anticipated to be constructed south of Camarillo as part of the Rancho Sierra Senior Supportive Housing (50 units) on Lewis Road.
Finally, there are a total of 224 dwelling units anticipated to be constructed adjacent to Hwy 126 in the Piru Expansion Area as part of the development of two recorded tract maps: the Reider subdivision, comprising 49 townhomes, and the Finch subdivision, comprising 175 new dwelling units. The Piru Expansion area is partially located within FEMA’s A99 flood zone.
In addition to the new housing outlined above, there are a number of redevelopment projects related to fire rebuilds. Between 2017 and 2018, 337 residential dwelling units were destroyed by the Thomas and the Woolsey Fires, which together burned more than 377,000 acres, most of which were located within Ventura County. As of 2020, rebuilding efforts have included issuance of 122 Planning Permits, 87 Building Permits, and the rebuild of 40 residential units. Many of these units were located in high-fire hazard areas.
Efforts by the County Planning Division are ongoing to implement programs outlined for the disadvantaged communities within the El Rio/ Del Norte Area Plan and Saticoy Area Plan that would accommodate additional development in these areas through roadway, sewer, and water infrastructure improvements.
The County also continues to improve regulatory pathways that support the development of additional affordable housing and agricultural worker housing throughout the County via an update to the General Plan Housing Element, as well as zoning amendments for agricultural worker housing regulations and accessory dwelling units.

The 2040 Ventura County General Plan Background Report included an inventory of both residential holding capacity and residential development potential. The unincorporated residential development potential was estimated to be 1,361 units (Section 3.7, Table 3-19). The residential development potential accounted for parcels on vacant and underutilized land, as well as other constraints such as steep slopes and floodways. If second dwellings, farmworker housing, Channel Islands University housing, and vacant OS, AE, and RA zone parcels with single-family potential are included, the remaining residential development potential is 28,228 units (Section 3.7, Table 3-22).
The County of Ventura’s General Plan Annual Report details that Unincorporated Ventura County’s Regional Housing Needs Allocation (RHNA) for the period from 2014 to 2021 was 1,015 units. As of 2019 the County has authorized permits for 590 of the 1,015 RHNA units (Exhibit 1, page 7). The Ventura County 2040 General Plan, Chapter 3 Housing Element includes the final RHNA allocation for the period of 2021-2029 which is 1,262 units (Section 3.2, Table 3-1). 524

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 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 1-4.
Development and permitting capabilities are presented in Table 1-5.
An assessment of fiscal capabilities is presented in Table 1-6.
An assessment of administrative and technical capabilities is presented in Table 1-7.
An assessment of education and outreach capabilities is presented in Table 1-8.
Information on National Flood Insurance Program (NFIP) compliance is presented in Table 1-9.
Classifications under various community mitigation programs are presented in Table 1-10.
The community’s adaptive capacity for responding to the impacts of climate change is presented in Table 1-11.

Criterion Jurisdiction Rating
Financial resources devoted to climate change adaptation High Comment:The County funded the 2020 Climate Action Plan, which is a component of the 2040 General Plan, and has provided matching funds for sea level rise planning grants. The County Executive Office’s Sustainability Division has staff devoted to climate action and adaptation programs, including an additional fixed-term position focused on supporting Climate Action Plan implementation that was approved in June 2020. The County also contributes membership funds to BEACON.
Local authority over sectors likely to be negative impacted High Comment:The County exercises land use authority in the unincorporated County.
Public Capacity
Local residents’ knowledge of and understanding of climate change risk Medium Comment:Many residents have a general understanding of climate change risks, but ongoing outreach and education is needed for the broader community.
Local residents’ support of adaptation efforts Medium
Comment:While most residents support adaptation efforts, they may be resistant if new requirements impact them financially.
Local residents’ capacity to adapt to climate impacts Low Comment:Applications for new development and redevelopment have rarely included voluntary climate adaptation features, but some features are required to be included according to 2040 General Plan policies. The County has allowed redevelopment in areas impacted by wildfires.
Local economy’s current capacity to adapt to climate change impacts Medium Comment:The agricultural industry is a substantial contributor to the local economy, with an estimated gross value in 2020 of over 1.9 billion dollars, and employing over 40,000 individuals. The County (~8,000 employees) and Naval Base Ventura County (>16,000 employees) are the two largest local employers and both are planning for climate change impacts. Additionally, the City of Port Hueneme is conducting a General Plan update that will include a vulnerability assessment and planning for sea level rise impacts at the Port of Hueneme.
Adaptive capacity is highly dependent on the scope and severity of climate impacts. Rebuilding levees, managed retreat, and rebuilding/relocating buildings and infrastructure in the face of extreme flooding and sea level rise are costly adaptation measures and, in many cases, would require substantial public funding and a multi-jurisdictional approach to implement.
Local ecosystems’capacity to adapt to climate change impacts Low Comment:A 2019 report by the Western Regional Climate Center indicated that, as a result of climate change Ventura County will experience air temperature increases, a greater number of extreme heat days annually, and an increased number of annual dry days leading to fewer but more intense rainfall events. Based on these findings, it is anticipated that such changes will lead to challenges in evapotranspiration and crop cultivation, increased potential for flash flooding and/or debris flows, increased susceptibility to drought, and longer wildfire seasons. More work needs to be done to evaluate how ecosystems that often straddle jurisdictional boundaries can migrate and adapt. More community education and benefit-cost analysis is needed to demonstrate how ecosystem services can minimize or abate climate change impacts. https://wrcc.dri.edu/Climate/reports.php https://wrcc.dri.edu/Docs/VenturaClimate2019_bookmarked.pdf.

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. 532
Ventura County Multi-Jurisdictional Hazard Mitigation Plan 1-14
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:
TheVentura County 2040 General Plan, Hazards and Safety Element was updated in September, 2020. The update also included a Water Resources Element and a Climate Action Plan.
TheNon-Coastal Zoning Ordinance (NCZO)includes standards for hazard mitigation and abatement relative to high fire hazard areas, earthquakes, geology and floods. Recent updates to the NCZO added water efficient landscaping standards and a wildlife corridor overlay zone that includes new standards in fencing and lighting to promote the movement of wildlife.
TheCounty’s Local Coastal Program (LCP)is comprised of the Coastal Area Planand Coastal Zoning Ordinance (CZO). The CZO includes standards for hazard mitigation and abatement related to beach erosion, geology, earthquakes, and floods.
TheVentura County Subdivision Ordinancerequires consideration of both geologic and flood hazards during the siting and design of proposed lots. Additionally, it requires consideration of wildfire hazards when a proposed subdivision is located in a “state responsibility area” or a “very high fire hazard severity zone”.
Ventura County Emergency Operations Planaddresses the County’s planned response to hazard events.
Ventura County Building Codeis the local adoption of the State codes Title 24
1.5.2 Opportunities for Future Integration
The capability assessment 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 offer opportunities for future integration or expanded integration with this mitigation plan:
The Ventura County 2040 General Planincludes policies and programs for hazard mitigation and abatement relative to high-fire hazard areas, earthquakes, geology and floods, as well as climate change adaptation related to droughts, sea level rise and coastal erosion. The County will re-link the General Plan with this HMP once this HMP update is approved. This will enable compliance with AB 2140.
The County’sInitial Study Assessment Guidelines (ISAGs)are in the process of being updated and this may be an integration opportunity.
The County’sNCZOis periodically amended per Board of Supervisors directive or as required by state law. Updates per new fire codes related to brush clearance and fire prevention may be needed.
TheCounty’s LCPincludes standards for hazard mitigation and abatement relative to beach erosion, geology, earthquakes, and floods. The policies and standards related to environmentally sensitive habitat, coastal hazards, and sea level rise are being consolidated and updated, and this effort could present an opportunity for future integration. 533

A30-mile section of U.S. Route 101 (US 101) from Santa Barbara to Ventura was shut down for two weeks as sections filled with two feet (60 cm) of mud and debris, some of which also reached beaches 2.25 miles (3.6 km) from the mountains. Following the closure, access to Santa Barbara from the Los Angeles area was limited to a 260-mile (420 km) detour around the Los Padres National Forest or through the use of private ferries to Ventura. This closure severely impacted commerce throughout the county. Based on commuter surveys conducted by the U.S. Census Bureau (2013) and Department of Transportation estimates, in 2017 an average of 2,300 vehicles (2,400 workers) commuted daily from Santa Barbara to Ventura County, and approximately 10,000 vehicles (11,500 workers) commuted from Ventura, in addition to approximately 3,700 commercial trucks.

NA 12/11/2015Strongwaves (up to 15 ft.)from a large westerly swell event resulted inevacuation and closure of the Ventura and Port Hueneme piers. Heavy surf caused approximately 15 pylons to break off the sides of the Ventura pier—triggering an extended (four month) closure while repairs were made. Pier repairs cost $1.4 million. Localized flooding of beachfront homes in the Pierpont neighborhood and nearby streets also occurred Harbor Boulevard between Sanjon Road and California Street in the city of Ventura had to be closed due to flooding.
Erosion from this event substantially altered the beach profile along Ventura State Beach near the pier, including impacts to Surfer’s Point as well as other exposed coastline areas.
At Naval Base Ventura County, officials temporarily closed Family Beach and a nearby campground because of high surf. Farther east along Pacific Coast Highway, State Parks relocated campers inland from the beachside Thornhill Broome State Beach Campground after the combination of high tide and the swell flooded the east and west ends of the campground.

a. The risk category was increased to High, based on jurisdiction-specific vulnerabilities.
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 this 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: 63 Number of FEMA-identified Severe-Repetitive-Loss Properties: N/A Number of Repetitive-Loss or Severe-Repetitive-Loss Properties that have been mitigated: N/A 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:
Prioritization of Open Space / Natural Resource Areas—In 2015, the U.S. Department of Agriculture named Ventura County the most desirable place to live in America. Ventura’s mild climate, varied topography, bountiful open space and natural resources, and proximity to additional natural resource areas are a large part of its draw for residents and visitors. Vast tracts of the unincorporated County lie adjacent to, or within, the Los Padres National Forest, Santa Monica Mountains National Recreation Area, and the Pacific Ocean. Valuation of these resources, and of our interface with these open space areas is outside the scope of FEMA’s traditional risk analysis tools (e.g., property/structural damage estimates, loss of life, and critical infrastructure inventories, insurance claims), which can result in radical underestimation of disaster impacts to recreation, tourism, and the overall desirability of living and working here.
Santa Ana Winds and Planned/Unplanned Utility Outages—Warm, dry northeasterly winds are a local weather phenomenon in Southern California that can result in downed trees and power lines, blowing dust and air quality concerns. Although the winds themselves do not cause wildfires and rarely rise to the level of an area-wide disaster on their own, they exacerbate 537
1. Ventura County (Unincorporated Area)
1-19
critical fire weather conditions in our area and substantially complicate wildfire response and containment. These winds may occur throughout the year, but are typically most common from October to March. Nearly all of the region’s significant wildfires have occurred in conjunction with strong Santa Ana wind conditions. Local power outages have been enacted with increasing frequency by utility companies in response to high wind/low humidity conditions, both within Ventura County and adjacent counties. Supporting adaptation of local businesses and individual residents to sporadic utility outages triggered by potential wind events, as well as critical facilities (e.g., communications towers and other energy infrastructure) should be prioritized.
Localized Flooding—Many communities within the unincorporated County are located adjacent to rivers (e.g., Santa Clara River, Ventura River, Sespe Creek, Piru Creek, Lockwood Creek) that are prone to flood to varying degrees during periods of heavy rainfall. The effects of this flooding range from localized road closures to damage to property (e.g., flooded croplands), vehicles, and buildings.
Ventura County Public Works Agency – Watershed Protection’s (VCPWA-WP’s) Critical Facilities in the Unincorporated Areas—Based on the fact that virtually all of VCPWA-WP’s critical facility assets were constructed to provide flood protection and/or are geospatially located proximate to and/or in flood plains, and as documented in Table 1.8 Past Natural Hazard Events above, during the aforementioned 56-year period, VCPWA-WP’s critical facility flood protection assets experienced $81 Million in damage from flooding, severe storms and severe weather events, VCPWA-WP has ranked Flood risks as “High” in Table 1.9 above.
Matilija Dam Seismic Risk Vulnerability—Matilija Dam in the Ventura River watershed is vulnerable to seismic failure. Many communities are at risk of inundation. Implementation of the Matilija Dam Ecosystem Restoration Project (MDERP) would address this risk while also opening 17 miles of habitat for endangered steelhead trout. MDERP comprises several downstream flood protection and water supply reliability components that must precede removal of the dam, some of which have been completed or are at various stages of completion (alternatives analysis, design, or construction).
Levee Rehabilitation and Certification Projects in Unincorporated Areas—Ventura County Watershed Protection is engaged in preliminary design and CEQA work for levee retrofit and/or flood-protection enhancement projects required to certify all its levees in compliance with federal levee certification requirements. Major levee rehabilitation and ultimate certification projects in the unincorporated areas include: the Ventura River Levee (VR-2) located in the unincorporated community of Casitas Springs, and the Live Oak Acres Levee located in the near the unincorporated community of Oak View. VCPWA-WP is working with FEMA, the U.S. Army Corps of Engineers (USACE), as well as affected cities, residents, and property owners throughout Ventura County to marshal scarce Federal, State, and local funding resources necessary to complete five very important levee retrofit public safety and flood protection projects. Once all VCPWA-WP’s levee retrofit projects are completed, VCPWA-WP’s levees will fully comply with applicable Federal Levee Certification requirements found in 44 CFR 65.10. At best, full completion of VCPWA-WP’s five levee rehab projects will require a minimum of five to ten years, and could take longer, depending on final engineering design plan results, environmental considerations, and availability of project funding required to construct the rehab projects.
Unincorporated Area Pump Stations Vulnerable to Sea-Level Rise—San Nicholas, Santa Monica, and Santa Paula Pump Stations lift stormwater from low elevation coastal neighborhoods and discharge directly to the Pacific Ocean. The Santa Monica and Santa Paula Pump Station outlets are frequently clogged during high tide and heavy surf events, causing the 538
Ventura County Multi-Jurisdictional Hazard Mitigation Plan 1-20
pumps to shut off and requiring manual removal of sand to ensure the coastal communities do not flood. With sea level rise, the risk increases. While not currently afflicted with the propensity for sand to clog its outlet, San Nicholas Pump Station is vulnerable to failure as sea level rises.
The pumps in each facility are over 40 years old and do not have on site backup generators, making them vulnerable to power failures, which cause alarms to sound signaling the need for immediate emergency response. All three facilities need constant repair due to corrosive salt air and water. Upgrades are needed, but more land is required for truly effective solutions, and adjacent land is occupied by high value coastal residences.
Ormand Lagoon Coastal Estuary Vulnerable to Sea Level Rise—Ormond Lagoon is a coastal estuary open to the ocean only during rain events and for a variable period thereafter depending on time between rain events, tides, etc. Sea level rise may reduce the ability of storm runoff from Ormond Lagoon Waterway and Tšumaš Creek to breach the lagoon and flow into the Pacific Ocean. Without a Beach Elevation Management Plan, the following are vulnerable to flooding from storm water backed up in the lagoon: the adjacent Oxnard Wastewater Treatment Plant and Advanced Water Purification Facility, the New-Indy recycled containerboard mill, the Halaco Superfund Site, local residences and roads. Restoration of the Ormond Wetlands complex may help reduce flood potential.
Homeless Population—The size and distribution of the homeless population in the unincorporated area is not easily quantified, but has been increasing in recent years and exacerbates hazard risks and mitigation costs. During a January 2020 point-in-time survey coordinated by the County Executive Office, 128 homeless individuals were counted as residing within the unincorporated County area. Many homeless individuals within the unincorporated area inhabit encampments within the Ventura and Santa Clara river bottoms, where both wildfires and flooding risks are regular concerns. Unsheltered living locations have negative impacts on watershed viability and resilience in addition to posing risks to the broader community. The presence of unauthorized habitation within the watersheds increases wildfire risks (e.g., accidental starts from cooking/warmth fires and arson) as well as the cost of hazard mitigation actions (e.g., brush clearance for wildfire hazard abatement and trash and debris removal efforts prior to winter storm season). Communication barriers, fear of government officials and law enforcement, substance abuse issues, and mental health issues can complicate public outreach and hazard awareness efforts to homeless individuals, and confound accurate assessments of hazard risk and disaster damage.
Importance of Agriculture and Potential for Undervaluation of Drought and Ag/Biological Risks—Agriculture, in the forms of ranching and farming, has been a keystone of Ventura County’s economy since its inception. With fertile soils and a mild climate, Ventura remains one of the leading counties for agricultural production in the state. In addition to a variety of row crops and nursery products, the county is one of the top producers of citrus, avocados, and strawberries in the nation. Much of the cultivated land lies within the unincorporated County areas of the Oxnard Plain and Santa Clara River Valley. In addition to generating direct on-farm employment and revenue, agricultural production supports a wide range of other businesses, including packinghouses, equipment dealers, chemical applicators, pest-control firms, labor contractors, fertilizer and other supply dealers, trucking firms, fuel distributors, and repair and manufacturing facilities. Altogether, farming and farm-dependent businesses provide an estimated 43,000 jobs in Ventura County, more than any other sector of the economy except services. Agriculture and agriculture-related businesses account for about 4.4 percent of overall economic activity in Ventura County, generating $2.1 billion in revenue and $76 million in indirect business taxes annually. One in 10 county residents relies to some degree on income derived from farming. However, drought and agricultural/biological hazards (e.g., invasive crop 539
1. Ventura County (Unincorporated Area)

pests and disease) do not lend themselves to evaluation using FEMA’s traditional risk analysis tools (e.g. property, structural damage estimates, loss of life, critical infrastructure inventories), which results in underestimation of the disaster impacts/costs that these hazards can have on the local environment, economy, and area communities.
Unauthorized Immigrants—Ventura County’s farm bureau estimates there are about 36,000 immigrant workers in the county, many of them undocumented. Unauthorized immigrants may be disproportionately affected by disasters (e.g., wildfires, flooding, pandemics), particularly those that impact agricultural operations in the unincorporated county areas where many work as farm laborers. Language/ communication barriers and fear of government and law enforcement personnel can complicate public outreach and education efforts to these individuals.
Mitigation actions addressing these issues were prioritized for consideration in the action plan in this annex.

VUC-17
Comment:Ventura County Public Works Agency—Roads and Transportation Department (VCPWA-RT) is responsible for the operation and maintenance of County roads, bridges, ditches, and culverts in the unincorporated areas of Ventura County. VCPWA- RT conducts annual ditch cleaning and culvert cleaning before winter storm season to maintain the capacity of ditches and proper drainage flow to mitigate roadway flooding in rural areas of the county. In addition to the annual cleaning of ditches and culverts, the VCPWA-RT is actively working to rehabilitate Bridge Road Bridge (#442) which is currently in design and environmental permitting phase and is expected to be completed in 2023. Replacement of Catalina Drive Bridge (#384) was completed in May 2020 and replacement of Casitas Vista Road Bridge (#327) was completed in September 2020. Mupu Road Bridge and the Wheeler Canyon Road Bridge improvements projects were completed in 2016-2017. The VCPWA-RT is developing a Bridge Management Program to maintain County bridges. The program will identify and prioritize VCPWA- RT’s 158 bridge structures which include 81 bridges on the National Bridge Inventory and 77 other structures. This program will identify budget needs, and schedules for preventive maintenance as well as budget for required rehabilitation or replacement of VCPWA-RT maintained bridges for short and long-term planning needs. The Bridge Management Program is expected to be completed in calendar year 2021. In 2020-2021, VCPWA-WP continued to clean flood control channels and catch basins to prepare for winter storm seasons. VCPWA-WP also secured Proposition 1 grant funding for the Santa Ana Bridge and Camino Cielo Bridge replacement projects which are managed by VCPWA-RT (both are components of the MDERP). The design of Camino Cielo Bridge is progressing towards 30% millstone. For the Santa Ana Bridge project, a construction contract was awarded in March 2021 with an estimated completion date of December 2022.

2.2 JURISDICTION PROFILE
2.2.1 Location and Features
Camarillo encompasses 19.86 square miles in west Ventura County at the base of the Conejo Grade, within the Oxnard Plain. The City is some eight miles from the ocean and the Pt. Mugu entrance to Naval Base Ventura County. Homes along the City’s northern border are nestled among rolling hills and citrus groves; the northernmost boundary traverses the Las Posas Country Club. Pleasant Valley Road designates much of Camarillo’s southern border, though the southernmost point is on Howard Road, near the southeast corner of the City. The eastern edge of Camarillo is situated partially up the Conejo Grade, along the Ventura Freeway (Hwy 101). Camarillo’s furthest point west is at the end (cul-de-sac) of Del Norte Road, just north of Hwy 101.
552
Ventura County Multi-Jurisdictional Hazard Mitigation Plan 2-2
2.2.2 History
The City of Camarillo was incorporated in 1964. In 1837, a large expanse of what would be the Conejo and Pleasant Valleys was established though a Mexican land grant, which Juan Camarillo purchased in 1875. Juan’s sons, Adolfo and Juan, Jr., would govern the 10,000-acre Rancho Calleguas for many years. Adolfo oversaw the development of the Camarillo House and Ranch in 1892, and his brother would have a prominent role in the construction of the St. Mary Magdalen Chapel in 1913.
In 1899, a line of the Southern Pacific Railroad was extended from Somis to Oxnard. At the time, a businessman named John Sebastian relocated a store and post office that were displaced from an area called Springville by the new rail line. When asked to provide a name for the new location of the store and post office, Sebastian suggested Calleguas, though the post office representative felt that name was confusing. Sebastian then proposed calling the area Camarillo, and by 1901 it was the official name for the settlement.
For years, from horse-drawn wagons to early automobiles, the route from Thousand Oaks north down the Conejo Grade involved 24 switchbacks. The journey was quite a trek, especially during warmer days. As travelers looked down the grade toward present day Camarillo, they often commented on it being such a pleasant valley.
Eventually, the region from Somis south to Pt. Mugu became known as Pleasant Valley and would be an integral part of the larger farming industry in Ventura County.
In 1942, with America involved in World War II, Naval Base Ventura County was commissioned, and a military airfield was built near Camarillo. In 1945, the airfield was officially known as Oxnard Air Force Base. The County of Ventura purchased the site in 1976 and began the transformation of the base to what is now Camarillo Airport.
In the early 1960s, a movement by the City of Oxnard to annex Camarillo galvanized community leaders, who organized a push for cityhood. In September 1964, cityhood was approved by voters and the following month Camarillo was officially recognized as an incorporated city. At the time, the City had approximately 12,000 residents, and an area of 5.5 square miles.
2.2.3 Governing Body
Camarillo is a general law city. The five-member City Council is the governing body with the responsibility of adopting the HMP. The responsibility for implementing the plan is shared by the Office of the City Manager, and the Community Development and Public Works Departments.
2.3 CURRENT TRENDS
2.3.1 Population
Camarillo has an estimated population of 70,261 (California Department of Finance estimate 2020).
Camarillo is currently growing at a rate of 1.42% annually (https://worldpopulationreview.com). 553

2.3.2 Development
Table 2-2 summarizes development trends in the period since the preparation of the previous hazard mitigation plan, as well as expected future development trends.
Table 2-2.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.
Annexations since the County’s last HMPupdate included a 3-acre parcel, initiated by the City, for the Camarillo LDS Church (n/e corner of Las Posas Road and Camino Alvarez); also, properties near the n/w corner of Lewis (Hwy 34) and Las Posas Roads were annexed for the development of the City’s new desalter plant. Construction is underway, and the desalter could be operational by early 2022. The City annexed 7.81-acres for the project from the Ventura Co.
Resource Conservation District, 4.5-acres of which is under the purview of the Camarillo Sanitary District.
Is your jurisdiction expected to
annex any areas during the
performance period of this plan?
No
Are any areas targeted for
development or major
redevelopment in the next five
years?
Yes.Over the past five years Camarillo has had significant residential construction activity, which is expected to continue for several years. A prominent commercial development is also underway just south of the 101 Freeway, and a steady progression of reuse and new industrial projects is anticipated.
If yes, briefly describe, including
whether any of the areas are in
known hazard risk areas
The primary natural hazard concerns for Camarillo include earthquakes and liquefaction, and wildland fires. Ongoing drought and dry vegetation continue to pose an elevated risk for fires, though the main areas of concern are in existing hillside communities in the northern portions of the City. The main faults in/near Camarillo include the Bailey, Simi-Santa Rosa, and Wright Faults. While these faults have limited intersection with properties proposed for development, major ruptures along the state’s larger fault lines could generate substantial ground movement -- though to what extent is difficult to forecast. As is the case in much of Ventura County, liquefaction is a potential threat connected to earthquakes. Approximately 25% of Camarillo’s soil is identified as being in liquefaction zones, primarily in the southeast and southwest sections of the City.
Permits for new construction issued
since the preparation of the previous
hazard mitigation plan. (For single-
family, each residence equals one
permit; for multi-fam., the numbers are
total units. Multi-fam. refers to
apartments, townhomes, and duplexes.
A permit for one apartment building
may include 20 units.)

Criterion Response
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: 0
Landslide: 0
High Liquefaction Areas: 0
Tsunami Inundation Area: 0
Wildfire Risk Areas: Please see clarification below.
Of the considerable residential development in Camarillo over the past 5+ years, no units have been built, or are currently under construction within a 100-year flood zone. During this period, approximately 350 residences (low-medium-high density) have been built in 500-yr. areas, and another high-density project (385 units) is pending approval. There is a low-income project (75 units) proposed for a 2.5-acre site that is owned by the City; if these apartments are ultimately constructed, the project would likely require flood mitigation measures (100-yr.).
As noted, areas of greatest concern for wildland fire, and those most involved in PSPS events, are in the northwest section of Camarillo, and parts outside (north of) the City. A large project with 281 homes (single-family and duplexes) is under construction approximately 0.8-miles west of a high fire risk zone, with a very-high zone just beyond. This development, for persons 55 years and older, is located east of Hwy 34, on the north side of Upland Road. Another project that is currently under review would result in 248 low-medium density homes in a section of the Camarillo Springs Golf Course, which lies in a very-high fire risk zone.
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.
Under current zoning, and considering sites under construction or entitled for building, about 60- acres of land is under review for potential housing projects. Over 150-acres are proposed for changes in zoning for industrial projects. There are also 46-acres of commercially-zoned land just off (south of) the 101 Freeway, at Las Posas Road. This site has the potential for 325,000 sq. ft. of retail, though internet sales have changed the brick/mortar outlook for many retailers.
Additionally, another 25-acres of vacant land could be considered for recreational uses (ice rinks, bowling, etc.) in the future.
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 planning 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.

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:
City of Camarillo General Plan, Safety Plan, Policy SAF-1.1a– Incorporate new and updated hazards information relevant to the City of Camarillo into the Safety Element, Emergency Operations Plan, and/or Local Hazard Mitigation Plan, as appropriate.
City of Camarillo, Emergency Operations Plan (EOP), 2021 (pending approval)—Section Eight-Hazard Summary for City of Camarillo presents a summary of all the hazards the City is subject to and references the Ventura County Multi-Hazard Mitigation Plan for more specific information.
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, Title 16, Chapter 16.34.340, Hazard Mitigation Plan—Identifies that the planning commission shall consider whether proposed development is in or affects a known floodplain, practical alternatives to the proposed development if in a floodplain, impacts of the project on the floodplain and plans to mitigate the impact of the development on the floodplain. 561

2.5.2 Opportunities for Future Integration
The capability assessment 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:
Climate Action Plan—The Climate Action Plan is a comprehensive roadmap that outlines the specific activities that an agency will undertake to reduce greenhouse gas emissions. Currently, the City does not have a Climate Action Plan but is planning to develop one in the near future.
Capital Improvement Projects—Capital improvement project proposals may take into consideration hazard mitigation potential as a means of evaluating project prioritization.
Post-Disaster Recovery Plan—The City does not have a recovery plan but may consider developing one as a mitigation planning action if funds become available. The plan will build on the goals and objectives identified in the hazard mitigation plan.
Taking action to integrate each of these programs with the hazard mitigation plan was considered as a mitigation action to include in the action plan in this annex.
