10 TO: CLAYTON CITY COUNCIL
FROM: Jeremy Crone, Police Chief
DATE: October 21, 2025
SUBJECT: Consider Adopting Resolution 36-2025 of the City Council of the City of Clayton Amending the Effective Hours for Non-turn Signs near Mount Diablo Elementary School.

Agenda Item: 4.b

STAFF REPORT

RECOMMENDATION
Approve the attached resolution

BACKGROUND
In September of 2022, the City Council authorized the addition of U-Turn signs and time restrictions on Four Oaks Lane to address traffic flow issues that caused traffic to back-up during the school congested ingress/egress (drop-off/pick-up) periods surrounding Mt. Diablo Elementary. Council Resolution 68-2022 was adopted on September 20, 2022, which included the placement of turn restriction signage and corresponding signage designating the times in which the turn restriction would be enforced. Enforcement hours signs were also placed on the turn restriction signs on Mitchell Canyon Road, as per the recommendation in the September 2022 staff report, corresponding to the intersection of Four Oaks Lane.

Per the Police Department, the placement of the signage was and continues to be effective in reducing congestion during drop-off and pick-up times, increasing pedestrian and vehicle safety, and has enabled the Police Department to appropriately enforce violations.

It was recently brought to the attention of the Police Department that the times of enforcement for turning movements no longer accurately aligns with the drop-off and pick-up times at Mt.

Diablo Elementary. This has created an enforcement gap and confusion for drivers, the school, and residents.

ANALYSIS
Per Resolution 68-2022 the enforceable hours, during school days, were to be as follows:

Mondays, Tuesdays, Thursdays, and Fridays: 7:00 to 8:15 a.m. and 2:00 to 3:00 p.m. Wednesdays: 12:05 to 12:50 p.m.

The current turn restriction signs read as follows (see attached):
11 School Days
Mon, Tue, Th, Fri 7:00 AM to 8:00 AM and 2:00 PM to 3:00 PM Wed Only 7:00 AM to 8:00 AM and 12:15 PM to 1:15 PM
The current Mt. Diablo start and end times for Kindergarten – 5 th Grade (bell schedule) are as
follows:

Monday, Tuesday, Thursday, and Fridays: 8:00 a.m. Start and 2:30 p.m. Dismissal Wednesdays: 8:00 a.m. Start and 1:20 p.m. Dismissal
The Police Department consulted with Mt. Diablo Elementary and confirmed the school does not plan to adjust their bell schedule anytime in the near future and indicated having the turn restriction signage more accurately align with their bell schedule would be helpful.

The Police Department recommends the replacement of the existing time restriction portion of the signage with updated time restriction signage that appropriately and accurately covers the heavy congestion times that correspond to the current bell schedule at Mt. Diablo Elementary School as follows:

Monday, Tuesday, Thursday, and Friday: 7:15 a.m. to 8:15 a.m. and 2:00 p.m. and 3:00 p.m. Wednesday: 7:15 a.m. to 8:15 a.m. and 12:45 p.m. to 1:45 p.m.

The new time brackets would allow for minor changes made by the school to their bell schedule, should they do so in the future, without the need to purchase new signs.

The City Manager has evaluated the proposed amendments to the turn sign enforcement hours and concurs with the Police Department’s recommendations.

CEQA
This proposed action is not a project as defined by CEQA.

FISCAL IMPACT
If approved by the City Council, direction would be given to public works maintenance staff to procure the signs (ten signs – see attachment 4). The estimated cost of the signs and incidental materials is approximately $1,000 with City-provided labor for installation.

18 TO: CLAYTON CITY COUNCIL
FROM: Kraig Chalem, Senior Planner
DATE: October 21, 2025
SUBJECT: Consider Adopting Resolution 37-2025 of the City Council of the City of Clayton to Adopt 2024 Contra Costa County Local Hazard Mitigation Plan - City of Clayton Annex
Agenda Item: 4.c

STAFF REPORT

RECOMMENDATION
That the City Council adopt the attached Resolution approving the 2024 Contra Costa County Local Hazard Mitigation Plan – City of Clayton Annex.

BACKGROUND
The Hazard Mitigation Plan was prepared in response to the Disaster Mitigation Act of 2000 (DMA 2000). DMA 2000 requires state and local governments to prepare mitigation plans to document their mitigation planning process, and identify hazards, potential losses, mitigation needs, goals, and strategies. This type of planning supplements the City of Clayton emergency management planning programs.

Towards the later part of 2023 and in 2024, City’s Planning staff worked with Contra Costa County (County) and other local jurisdictions to update the 2018 Contra Costa County Local Hazard Mitigation Plan (LHMP) in accordance with 44 CFR § 201.6(a)(4) - Local Mitigation Plans - which allows for local governments to work together to create a multi-jurisdiction plan.

The purpose of the LHMP is to establish a partnership, pool resources in order to create a uniform hazard mitigation strategy that can be consistently applied throughout the County and ensure eligibility for specified grant funding sources to make the County more disaster-ready and resilient. City of Clayton’s last adopted LHMP was on April 20, 2021.

DISCUSSION
The Contra Costa County (County) Base Plan was approved by the Federal Emergency Management Agency (FEMA) and the California Office of Emergency Services (CalOES) on September 23, 2024. Adoption of Clayton’s Annex by the City Council demonstrates the City’s commitment to the hazard mitigation goals and actions outlined in the LHMP. Adoption legitimizes the plan and authorizes responsible agencies to perform their responsibilities. Without adoption, Clayton will not have completed the mitigation planning process and will not be eligible for consideration for project grants under FEMA’s Hazard Mitigation Assistance programs, including the Hazard Mitigation Grant Program, Building Resilient Infrastructure and Communities Program and the Flood Mitigation Assistance Program. Adoption of the Annex 19 does not guarantee the City will be awarded future grants.

City of Clayton stakeholders and the public were given opportunities to be involved and provide feedback throughout the planning process: a public survey, County in-person and virtual public meetings, as well as City meetings, and other public engagement activities to encourage the review of the LHMP draft during the public comment period. The public meetings allowed the County and City to introduce the Plan update, identify additional hazards of concern that should be included, if any, and to provide input for the various mitigation measures intended to eliminate or reduce the negative impact on those hazards.

As required by DMA 2000, City of Clayton’s Community Development Department involved the general public, and external agencies were invited to contribute to the mitigation plan during the workshop held on December 4, 2023. The comments period for the Mitigation Plan ended on May 31, 2024. The LHMP was presented to the City Council by the Community Development Director at their meeting on May 7, 2024, but the LHMP was not followed through for adoption by City Council.

FISCAL IMPACT
There are no immediate fiscal impacts to adopt the City of Clayton’s Annex. Not adopting the Annex makes the City ineligible for consideration for project grants under FEMA’s Hazard Mitigation Assistance programs, including the Hazard Mitigation Grant Program, Building Resilient Infrastructure and Communities Program and the Flood Mitigation Assistance Program.

ENVIRONMENTAL REVIEW
The project is Categorically Exempt from CEQA Guidelines Section 15378 as an administrative activity of the government that will not result in direct or indirect physical changes in the environment.

WHEREAS, City of Clayton’s Community Development Department involved the general public, and external agencies were invited to contribute to the mitigation plan during the workshop held on December 4, 2023; and
21 Resolution 37-2025 2 of 2
WHEREAS, the 2024 Contra Costa County Local Hazard Mitigation Plan – City of Clayton Annex was presented to the City Council by the Community Development Director at their meeting on May 7, 2024; and

3.2. Brief History
In 1853, Joel Clayton purchased 40 acres of land in the Diablo Valley, established a general store, cattle ranch, the first vineyards, and laid out the streets and most of the community. Mr. Clayton’s involvement as a civic leader in the region led to the naming of the City of Clayton in his honor in 1857.

Clayton prospered during the coal mining boom in eastern Contra Costa County. The post office opened in 1861. Following a previous incorporation attempt in 1960, the City of Clayton was incorporated in 1964 to stave off an attempt by nearby Concord to annex the Cardinet Glen neighborhood in 1963. After steady expansion during the 1970s to the east and west from its original boundaries, Clayton's land area more than doubled in 1987 to near its present day boundaries with the annexations of the Dana Hills/Dana Ridge and Clayton Wood subdivisions, as well as the former Keller Ranch property that was developed during the 1990s with the Oakhurst Country Club.

On September 8, 2013, a wildfire ignited in Mount Diablo. Called the Morgan Fire, it started at the mercury mine area of Morgan Territory Road. The wildfire quickly spread and threatened homes and livestock within the City. Evacuations were ordered for several areas, including Oak Hill Lane and Curry Canyon.

It took over 1,000 firefighters and eight (8) aircraft to extinguish the wildfire. Full containment was announced on September 14, 2013, after burning 3,100 acres

3.3. Governing Body Format
The City of Clayton has a Council/Manager form of government. Policy making and legislative authority is vested in a five (5) member City Council consisting of a Mayor and four (4) Council Members. The Council Members are elected to four (4) year overlapping terms. The City Council has a one-year rotating Mayoral position that is elected by the Council. The City Council assumes responsibility for the adoption of this Plan, and the City Manager will oversee its implementation.

The City Council presides over and adopts the City’s annual budget and financial affairs; appoints commissions and committees; and hires and supervises the City Manager. City Council members are directly responsible for service to the citizens, businesses, and policies of the City. The City Manager advises the City Council, supervises personnel and all City departments; enforces ordinances and programs approved by City Council; and oversees day-to-day city government operations.

4. DEVELOPMENT TRENDS
California Law requires counties and cities to prepare and adopt a General Pan, a comprehensive longrange plan to guide community development. The General Plan must contain seven (7) state-mandated elements – land use, housing, circulation, safety, open space, conservation, and noise – and may contain additional elements as a jurisdiction sees fit. Additionally, the General Plan must comprise an integrated and internally consistent set of goals, policies, and implementation measures. The City of Clayton 28 2024 Hazard Mitigation Plan
Contra Costa County, California
City of Clayton Annex 4
adopted its General Plan under this law and has updated it several times over the years, including most recently in January 2023.

The Bay Area is the fifth largest metropolitan area in the nation and has seen a steady increase in population since 1990, except for a decrease during the Great Recession that began in 2008. Many cities in the region have experienced significant growth in jobs and population. While these trends have led to a corresponding increase in demand for housing across the region, the regional production of housing has not kept pace with job and population growth.

From 1990 to 2000, the City’s population increased by 47.1%, with a much smaller increase of 1.3% during the first decade of the 2000s. This large increase between 1990 to 2000 can be explained by expansion and urbanization of the undeveloped lands to the north and east of the City center. These areas were developed into residential subdivisions and incorporated into the City. Between 2010 and 2020, the population increased by 1.6%.

Clayton is primarily a residential City with minimal industrial or commercial activity. Homes in Clayton are predominantly owner-occupied. The number of households in Clayton increased from 3,852 in 2010 to 4,232 in 2019 (380 new households). Renter-occupied households decreased by 86 households, from 385 in 2010. Specific development opportunity areas in and near the City include. • Town Center Specific Plan: The Town Center Specific Plan (TCSP) establishes goals and policies for development in the Town Center area. The purpose of the TCSP is to encourage appropriate commercial development while enhancing the area’s historic character. The TCSP identifies appropriate land uses in the Town Center and provides design guidelines for new buildings, walkways, parking lots, and landscaping. Land use regulations allow for a combination of commercial and multifamily residential development types. • Marsh Creek Road Specific Plan: The Marsh Creek Road Specific Plan (MCRSP) refers to an area of 475 acres south and east of Clayton in central Contra Costa County. This area is mostly undeveloped and is located at the edge of existing urban development. Several residential development proposals have been submitted within this area, but it is also viewed as an important natural resource by the local residents. The goal of the MCRSP is to maintain the unique rural character of the study area and designate appropriate sites for residential development. The policies in the MCRSP are intended to guide and regulate development in a manner that both protects the area’s natural amenities and affords recreational opportunities and public access.

Since 2018, none of the housing permits issued have been subject to these hazards categories. However, the potential development sites previously listed could be subject to the following hazards. • Special Flood Hazard Areas: 60 (some of the units in the 32 unit development on Oakhurst Drive are in the 500-year
floodplain, as are a portion of one (1) of the church-owned properties and some sites in the Town Center)
• Landslide: 0 (units have not been entitled, though sites on Clayton Road east of the Town Center would be adjacent to steep slopes that may have some landslide risk)
• High Liquefaction Areas: 0
• Dam Failure Inundation Area: 0
• Wildfire Risk Areas: 6 (approved houses at City’s southeastern boundary abut open grassland area; other sites near the golf course on Clayton Road are not entitled for a specific number of units but are also near open grasslands)

4.1. Changes in Priority
This Plan update prioritizes climate resilience (reducing greenhouse gas emissions from and energy demands of municipal operations, vehicles, and indoor space conditioning) as a means to reduce impacts of consequential hazards of climate change, including heat waves/extreme heat, drought, heavy rainfall, and flooding. Additionally, mitigation actions from the previous Plan were updated, and a more concerted effort on achieving equitable outcomes for all communities, including underserved communities and socially vulnerable populations, has been implemented.

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

A capability assessment was conducted for the City of Clayton and participating jurisdictions’ authorities, policies, programs, and resources. Goals and mitigation actions were developed using input from this assessment. This section also includes information regarding the City’s jurisdictions’ implementation of and continued participation in the National Flood Insurance Program (NFIP).

The Local Planning Team assessed the City’s capabilities that can contribute to the reduction of longterm vulnerabilities to hazards. The capabilities include the following categories:
• Planning and Regulatory Capabilities
• Administrative and Technical Capabilities
• Financial Capabilities
• Education and Outreach Capabilities
Additionally, ways to expand on and improve these existing policies and programs to integrate hazard mitigation into the day-to-day activities and programs of the City were considered. 31 2024 Hazard Mitigation Plan

6. HAZARD MITIGATION PLAN INTEGRATION
The information on hazards, risk, vulnerability, and mitigation contained in this Hazard Mitigation Plan is based on the best available data at the time of the Plan update. Plan integration consists of the incorporation of hazard mitigation into other relevant planning mechanisms (e.g., general planning and capital improvement planning). It includes the integration of natural hazard information and mitigation policies, principles, and actions into local planning mechanisms and vice versa. Additionally, plan integration is achieved through the involvement of key staff and community officials in collaborative 41 2024 Hazard Mitigation Plan

hazard mitigation planning. This section describes the City’s process for integrating information from this Hazard Mitigation Plan into other planning mechanisms.

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

Table 9. Past Plan Integration
Planning Initiative Description
Capital Improvement
Program
The Capital Improvement Plan should continue to utilize flexibility in the CIP to incorporate mitigation measures in planned projects and the project evaluation criteria which includes public health and safety, regulatory compliance, and grant funding requirements.

City General Plan
Upon each revision of the Hazard Mitigation Plan, the Safety Element is revised (no less than every eight (8) years). The Hazard Mitigation Plan is utilized to identify new information that was not available during the previous revision of the Safety Element, relating to hazards (i.e., flood and fire), and climate adaptation and resiliency strategies.

Emergency Operations Plan This Hazard Mitigation Plan is currently used as an essential tool to update the City EOP.

County Climate Action Plan
The strategies and actions in the County Climate Action Plan (CAP) integrate with the Hazard Mitigation Plan. For example, where possible, CAP and Hazard Mitigation Plan update cycles should be coordinated to ensure plan alignment of climate mitigation efforts.

6.2. Potential Future Integration
As the Hazard Mitigation Plan is implemented, the City of Clayton will use information from the Plan as the best available science and data on hazards. The capability assessment presented in Section 5 of this Annex identifies codes, plans, and programs that provide opportunities for integration. The citywide and local action plans developed for this Hazard Mitigation Plan are related to plan integration. The capability assessment identified plans and programs, listed in Table 10, that do not currently integrate goals and recommendations of this Plan but provide opportunities to do so in the future. 42 2024 Hazard Mitigation Plan

• Provides the following services – permit review, GIS, inspections, and engineering capability. • The City educates private owners and other stakeholders about the importance of flood insurance through public outreach events, workshops, and/or seminars. • Enforces local floodplain regulations and monitors compliance. • Floodplain management regulations meet or exceed FEMA or State minimum requirements.

8.2.1. Substantial Damage
Substantial damage, for the purpose of determining compliance with the flood provisions of the Municipal Code, means damage of any origin sustained by a structure by which the cost of restoring the structure to its before damaged condition would equal or exceed 50% of the market value of the structure before the damage occurred. (Municipal Code Title 15, Chapter 15.10 – Disaster Repair and Reconstruction)

8.2.2. Substantial Improvement
Substantial improvement, for the purpose of determining compliance with the flood provisions of the Municipal Code, means any repair, alteration, addition, or other improvement of a building or structure, whose cost equals or exceeds 50% of the market value of the structure before the improvement or repair started. If the structure has sustained substantial damage, any repairs are considered substantial improvement regardless of the actual repair work performed. The term does not, however, include either:
• Any project for improvement of a building required to correct existing health, sanitary, or safety code violations identified by the code official and that is the minimum necessary to assure safe living conditions.
• Any alteration of a historic structure, provided that the alteration would not preclude the structure’s continued designation as a historic structure. (Municipal Code Title 15, Chapter 15.10 – Disaster Repair and Reconstruction)

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

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

The Local Planning Team identified unique vulnerabilities and impacts to the following natural hazards, based on the hazards profiled in Volume 1 (Planning Area-wide Elements). • Earthquake
• Flood (riverine/creek, urban/flash flood)
• Landslide
• Severe Weather (heavy rainfall, severe thunderstorms, strong winds/damaging winds, heat wave/extreme heat, tornado)
• Wildfire
It was determined that the planning area did not have unique vulnerabilities and impacts to the following natural hazards; rather, its vulnerability and impacts are consistent with those experienced throughout the County.
• Climate Change
• Dam and Levee Failure
• Drought
• Sea Level Rise
• Tsunami
Note: Severe weather and flooding are profiled as the two (2) hazards. However, in an effort to have a more thorough risk assessment, the sub hazards (i.e., heavy rainfall, severe thunderstorms, strong winds/damaging winds, heat wave/extreme heat, tornado, riverine/creek flooding, and urban/flash flooding) were ranked individually. The hazard risk assessment methodology can be found in Appendix C of this Annex.

City of Clayton Annex 23
Hazards Vulnerabilities and Impacts
Earthquake
Clayton is located in a seismically active region and is not uniquely affected by earthquakes generally. There are no Alquist Priolo requirements in the City.

However, like other jurisdictions in the County, Clayton could be affected by movement along the Hayward Fault, which is a 45 mile long fault that runs through densely populated areas on the East Bay, parallel to the San Andreas Fault. The probability of experiencing a Magnitude 6.7 or greater earthquake along the Hayward Fault in the next 30 years is 33%. An earthquake of this magnitude has regional implications for the entire Bay Area, as the Hayward Fault crosses transportation and resource infrastructure, such as multiple highways and the Hetch-Hetchy Aqueduct. There are known active faults closer to Clayton, including the Concord Fault (under the adjacent City of Concord), which is considered to be under high stress and has a 16% probability of experiencing a Magnitude 6.7 or greater earthquake in the next 30 years; and the Mount Diablo thrust fault in the vicinity of Mount Diablo, which is just south of Clayton.

While the City is not uniquely vulnerable to seismic ground shaking, slopes (0% to 15%) found in the downtown Town Center area, and in the area immediately northeast of Clayton Road, contain alluvial soils that could amplify ground shaking in the event the Concord Fault shifts. The fault is not classified as active; however, there is preliminary evidence that the fault may have displaced recent landslide materials. Due to this, the fault should be treated as active unless evidence proves otherwise.

Additionally, the hilly terrain in and around the City makes Clayton uniquely vulnerable to landslides, which could be caused by ground movement. With a power transmission corridor spanning the City from southwest to northeast, and gas pipeline easements in the southeastern quadrant, the City has a unique risk for potential fire resulting from oil pipelines or power lines that are broken or downed during an earthquake.

Clayton's proximity to the Hayward Fault and the Concord Fault places several critical assets at risk. The densely populated areas along Marsh Creek Road and within the downtown area are especially vulnerable due to the concentration of older residential structures that may not meet current seismic standards.

Additionally, schools and community centers located near these fault lines are at risk of structural damage, potentially impacting vulnerable populations, including school children, elderly residents, and low-income households who may have limited resources for recovery and relocation. Due to limited mobility, the elderly population may have difficulty evacuating, especially those living alone. Furthermore, if an earthquake occurs during school hours, younger children may have heightened stress and fear as they are away from their families and may not fully understand how to respond.

Underserved populations, particularly low-income households and renters living in older, less structurally sound buildings, are at heightened risk during a major earthquake due to limited access to financial resources for retrofitting, insurance, and rebuilding. The City's emergency response systems should prioritize these populations to ensure swift aid and recovery. 48 2024 Hazard Mitigation Plan
Contra Costa County, California
City of Clayton Annex 24
Hazards Vulnerabilities and Impacts
Flood
(urban/flash flood, riverine/creek)
Clayton has a variety of creeks and streams within its boundaries, which could be subject to flooding. The principal stream running through Clayton is Mount Diablo Creek which originates on the steep north slopes of the 3,849 foot Mount Diablo and drains a watershed of approximately 30 square miles. It flows northerly and westerly through the cities of Clayton and Concord, the Concord Naval Weapons Station and eventually empties into Suisun Bay. In Clayton, Mount Diablo Creek is joined by Donner and Mitchell creeks, both of which originate on the slopes of Mount Diablo and by Peacock Creek, which flows from the Keller Ridge.

Some portions of the Clayton downtown Town Center are located within 100- year flood zones originating from Mount Diablo Creek.

Flooding has occurred from Mount Diablo Creek in the Town Center area of Clayton and in the floodplain between Clayton Road and Kirker Pass Road. The major floods affecting this area occurred in 1938, 1952, 1955 and 1963. The 1955 and 1963 floods both were estimated as 25-year floods. More recent storm events in 2023 greatly increased flows within the channel and caused notable bank erosion in some areas; however, no structures were damaged during that storm event. Despite these occurrences, Mount Diablo Creek is not considered a creek with a high flood history. The long floodplain between Mount Diablo and the City boundaries slows velocity and delays peak flows. As the Mount Diablo Creek watershed continues to develop, the potential for serious flooding and flood-related damage increases.

Low-lying residential areas along Main Street and surrounding neighborhoods, particularly those with an older housing stock, are highly vulnerable. Structures in these areas may lack proper flood defenses, such as raised foundations or waterproofing, making them vulnerable to severe damage in the event of significant flooding. Furthermore, underserved populations, including lowincome households in flood-prone areas, are at risk due to limited access to flood insurance and resources for recovery. Additionally, those with access and functional needs may be unable to evacuate in a timely manner and if isolated, emergency services may be delayed.

Efforts should be made to strengthen community outreach and flood preparedness programs in these areas, ensuring that vulnerable residents have access to early warnings and evacuation plans.

Hazards Vulnerabilities and Impacts
Landslides
The undeveloped regions of Clayton contain a number of potential geological hazards. These include slopes with unstable expansive soil, high erosion potential, evidence of springs, mudflow potential, rockslide potential and evidence of significant creep. While landslides may occur on slopes of 15% or less in unstable areas, the risk increases with steepness of slopes.

Areas of old slide deposits are most subject to continued failure. Grading without engineered requirements tends to reduce slope stability so that road cuts and the cut and fill pads typically prepared for hillside housing carry a greater risk of slope failure than undisturbed hillsides. However, fill slopes engineered to today's standards may result in a more stable situation than in nature, particularly where smaller slide deposits are improved or arrested.

Foothill areas of Clayton contain slope stability problems, which may be triggered by improper grading. In addition, foothill areas may experience local slope erosion, sedimentation or drainage problems, expansive soil reaction and other development limitations requiring corrective measures prior to any grading or construction. Ground rupture or slides along existing or suspected fault lines is also a possibility.

Homes and infrastructure along Marsh Creek Road and areas bordering Mount Diablo State Park are particularly vulnerable because there is a higher number of older residential structures that may not have been built with modern slope stability considerations. Low-income households in these areas may face significant challenges if their homes are damaged or destroyed in a landslide, as they may lack the financial resources necessary for repairs and rebuilding.

The elderly that live within these areas may become isolated from the community as they may have mobility issues that prohibit them from evacuating and may lack social connections and community support before, during, and after an emergency, such as a landslide.

Planning efforts should focus on bolstering slope stabilization and creating community evacuation plans tailored to these vulnerable populations.

Sea Level Rise

Hazards Vulnerabilities and Impacts
Severe Weather
(heavy rainfall, severe
thunderstorms, strong
winds/damaging winds, heat
wave/extreme heat, tornado)
Clayton is uniquely vulnerable to severe weather, and in particular, the effects of extended heat waves on older residents. Although the number of high school and college age residents (15 to 24 years old) saw a 4% increase from 2010 to 2019, the number of 55 to 64 year old residents also increased in the same timeframe. Overall, Clayton's population is aging, with residents' median age increasing from 39.5 years in 2000 to 46 years in 2019.

With several creeks within the City’s boundaries, Clayton is also uniquely vulnerable to heavy rainfall events, as discussed under the flooding hazard.

Clayton's vulnerability to severe weather is linked primarily to the impacts of heat waves/extreme heat and heavy rainfall. The aging population (approximately

38.9% is 65 years old and over) is particularly vulnerable to heat-related illnesses during heat wave/extreme heat events, especially those without access to cooling systems. Additionally, low-income households may struggle with the financial burden of cooling their homes during prolonged heatwaves.

Residential structures without sufficient insulation or cooling systems are at increased risk during these periods. Public buildings, such as the Clayton Library and community centers, could serve as cooling centers to support vulnerable populations. However, the elderly population and those with access and functional needs may have difficulty evacuating to a cooling center on their own.

Heavy rainfall may cause localized flooding, especially in areas with inadequate stormwater management infrastructure. Older buildings and homes that were not constructed with modern stormwater drainage systems or built to current flood-resistant building codes may be more susceptible to water damage during severe weather. Roadways, particularly near Marsh Creek Road, could be impacted by debris flow and minor flooding, affecting access to emergency services. The elderly and those with access and functional needs may face greater challenges in evacuating during severe weather events due to mobility limitations.

Tsunami
The Local Planning Team determined that the City does not have unique vulnerabilities and impacts to tsunamis; rather, the City’s vulnerability and impacts are consistent with those experienced throughout the County. 51 2024 Hazard Mitigation Plan

City of Clayton Annex 27
Hazards Vulnerabilities and Impacts
Wildfire
Clayton is identified as a Non-Very High Fire Severity Zone; however, it is surrounded to the north, east, and south by High and Very High Fire Severity Zones. Because the natural vegetation in the trail system and adjacent parklands is extremely flammable during the dry summer and fall seasons, wildfire is a serious hazard in the City of Clayton. Slopes, high winds, and difficulty in access increases the hazards. Traffic congestion in the case of fire can hinder firefighting. Isolated homes set in wooded canyons or on ridge tops with only one (1) narrow, winding, or steep road are subject to a high fire hazard, and burned slopes are highly subject to erosion and gullying from subsequent rains.

Clayton’s proximity to Mount Diablo State Park and the surrounding wildland urban interface (WUI) puts several assets at risk from wildfires. Residential developments along Marsh Creek Road and Oakhurst Drive, including the Oakhurst Country Club, are particularly vulnerable due to their proximity to open grasslands and forested areas that serve as fuel for wildfires. Older homes and structures not built to current fire-resistant standards are at greater risk for damage during wildfire events.

The City’s emergency response capacity, particularly for evacuation routes and shelters, may be strained in the event of a large wildfire. Vulnerable populations, including low-income households and elderly residents, may face challenges in evacuation due to mobility issues or lack of resources. Community outreach programs should prioritize fire prevention education and evacuation planning, particularly for underserved populations.

Fire mitigation efforts such as defensible space requirements around homes, especially in the WUI, are essential to reduce risk. However, due to financial limitations, low-income households may not be able to maintain wildfire mitigation efforts, such as defensible space. Addititionally, critical infrastructure, including water supply lines and electrical grids, is also at risk, which could hinder firefighting efforts and the provision of essential services during an emergency.

City of Clayton Annex 28
The City evaluated whether vulnerability and impact in hazard prone areas had increased, decreased, or remained the same for each natural hazard identified in this Hazard Mitigation Plan. Climate change, changes in population, infrastructure expansion, and economic shifts that can affect vulnerability were considered. For example, if planned development is in an identified hazard areas or is not built to the updated building codes, it may increase the community’s vulnerability to future hazards and disasters.

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

Table 16 outlines if climate change has increased or decreased the City’s vulnerability (i.e., exposure) and impact to each natural hazard over the past five (5) years, and the effect of climate change in the future probability of occurrence and impacts from each natural hazard.

9.1. FEMA National Risk Index
In the National Risk Index (NRI), risk is defined as the potential for negative impacts as a result of a natural hazard. The Risk Index is based on three (3) components – a natural hazards component (Expected Annual Loss), a consequence enhancing component (Social Vulnerability), and a consequence reduction component (Community Resilience). Using these components, the composite and hazard type Risk Index values are calculated for each community (county and Census Tract). Risk Index values form an absolute basis for measuring Risk within the NRI and are used to generate Risk Index percentiles and ratings across communities.4 Table 20 illustrates the Risk Index rating and score for the City of Clayton.

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

Table 20. Risk Index Score (FEMA National Risk Index)
Jurisdiction Rating Score
City of Clayton Very High 80.1
Risk Index scores are calculated using an equation that combines scores for Expected Annual Loss due to natural hazards, Social Vulnerability and Community Resilience (Expected Annual Loss x Social Vulnerability / Community Resilience = Risk Index).

9.1.1. Expected Annual Loss
The FEMA NRI Expected Annual Loss (EAL), the natural hazards component of the NRI, represents the average economic loss in dollars resulting from natural hazards each year. It is calculated for each hazard type and quantifies loss for relevant consequence types – buildings, people, and agriculture. The EAL score and rating represent a community's relative level of expected losses each year when compared to all other communities at the same level. Since the score is associated to a community’s risk; the higher EAL score results in a higher Risk Index score.5 Table 21 illustrates each hazard EAL for the City of Clayton.

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

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

9.1.2. Social Vulnerability
Social vulnerability, the consequence enhancing risk component of the NRI, measures the susceptibility of social groups to the adverse impacts of natural hazards, including disproportionate death, injury, loss, or disruption of livelihood. The Social Vulnerability score and rating represent the relative level of a community’s social vulnerability compared to all other communities at the same level. A higher Social Vulnerability score results in a higher Risk Index score.6 Table 22 illustrates the Social Vulnerability rating and score for City of Clayton.

Table 22. Social Vulnerability (FEMA National Risk Index) Jurisdiction Rating Score
City of Clayton Relatively Low 21.0
Social Vulnerability is measured using the Social Vulnerability Index (SoVI) published by the University of South Carolina’s Hazards and Vulnerability Research Institute (HVRI).

9.1.3. Community Resilience
Community resilience, the consequence reduction risk component, measures the ability of a community to prepare for anticipated natural hazards, adapt to changing conditions, and withstand and recover rapidly from disruptions. The Community Resilience score and rating represent the relative level of a community’s resilience compared to all other communities at the same level. Since the score is inversely proportional to a community’s risk; the higher Community Resilience score results in a lower Risk Index score.7 Table 23 illustrates the Community Resilience rating and score for the City of Clayton.

Table 23. Community Resilience (FEMA National Risk Index) Jurisdiction Rating Score
City of Clayton Relatively High 66.4
Community Resilience is measured using the Baseline Resilience Indicators for Communities (HVRI BRIC) published by the University of South Carolina's Hazards and Vulnerability Research Institute (HVRI).

9.1.4. Annualized Frequency
Annualized frequency is defined as the expected frequency or probability of a hazard occurrence per year. It is a natural hazard incidence factor for Expected Annual Loss, the natural hazards component of the National Risk Index. A higher annualized frequency value results in higher Expected Annual Loss and Risk Index scores. The annualized frequency is derived from either the number of recorded hazard occurrences each year over a given period or the modeled probability of a hazard occurrence each year (e.g., earthquake).
8 Table 24 outlines the annualized frequency for each hazard, based on FEMA NRI data, for the City of Clayton.

10. HAZARD RISK RANKING
Table 25 presents the local hazard ranking for the City of Clayton of all hazards of concern listed in Volume 1 (Planning Area-wide Elements) of this Plan. This ranking summarizes how hazards vary for this jurisdiction. As described in detail in Volume 1 (Planning Area-wide Elements) and Appendix C of this Annex, the ranking process involves an assessment of the likelihood of occurrence for each hazard, along with its potential impacts on people, property, and the economy. For further details on how the probability, extent, vulnerability, and impact factors in Table 25 were calculated, please refer to Appendix D of this Annex.

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

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

The City of Clayton agreed upon 32 mitigation actions that apply to the jurisdiction’s properties where they have jurisdictional responsibility and authority. Two (2) mitigation actions were completed. According to the City’s Hazard Vulnerability and Impact Assessment, the City is not vulnerable to sea level rise and tsunamis. Therefore, mitigation actions for these hazards are not required. A summary of the City’s mitigation actions status is listed in Table 26.

Table 26. City of Clayton Mitigation Actions Summary

Mitigation Actions per Hazard
Climate Change 8 Landslide 7
Dam and Levee Failure 1 Sea Level Rise 1
Drought 8 Severe Weather 10
Earthquake 5 Tsunami 1
Flood 13 Wildfire 8
These shared actions, some of which address all hazards, help to meet the following requirements:
• Does the Plan identify and analyze a comprehensive range of specific mitigation actions and projects for each jurisdiction being considered to reduce the effects of hazards, with emphasis on new and existing buildings and infrastructure?
• Does the Plan include one (1) or more action(s) per jurisdiction for each hazard identified within the risk assessment?
A detailed explanation of the Mitigation Strategy can be found in Chapter 5 of Volume 1 (Planning Areawide Elements). 61 2024 Hazard Mitigation Plan

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

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

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

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

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

The public meetings allowed the County to introduce the Plan update, identify additional hazards of concern that should be included, if any, and to provide input for the various mitigation measures intended to eliminate or reduce the negative impact to those hazards. Language translation assistance in Spanish was available in all public meetings. The public survey asked community representatives and members of the public to rate each of the hazards in terms of perceived risk. Furthermore, they were asked to rate “mitigation importance” for each of the identified hazards in the Plan. The information gathered from this survey was used to inform the hazard risk prioritization process, and to ensure the Plan adequately addressed the public’s concerns and priorities. The survey was available in English, Spanish, Tagalog, Traditional Chinese, and Simplified Chinese. A total of 17 respondents that lived in the City and three (3) that worked in the City participated in the survey. Please refer to Volume 1 (Planning Area-wide Elements) for further information and supporting documentation of the public meetings and public survey.

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

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

After the public comment period ended, no public feedback was received for the City of Clayton Annex.

However, in order to keep the Plan current after it is approved, the City will ensure that the public continues to be involved in the Plan and how it is carried out. Refer to Section B.2 of this Annex for further details on continued public engagement.

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

The City of Clayton Local Planning Team coordinated with its stakeholders to ensure that the public had an opportunity to learn about the Plan, mitigation actions planned for their community, and ways to get involved in the planning process. Outreach to the Clayton community involved a combination of in person, printed, and digital media starting on April 20, 2024, through the end of the public comment period on May 31, 2024. To ensure equitable outreach a calendar was created to strategize and map all events.

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

However, each plan participant was required to cross-reference the countywide list and identify the stakeholders that applied specifically to their jurisdiction. Not only did this help ensure that a comprehensive list was compiled as part of the stakeholder engagement, but it assisted each plan participant identify any additional stakeholders that may have not been on the list. Table 27 outlines the stakeholders the City of Clayton identified and provided an opportunity to review and provide feedback on the draft Plan and Annex, via the countywide stakeholders e-mail.

APPENDIX C. HAZARD RISK ASSESSMENT METHODOLOGY
As part of the Contra Costa County Office of Emergency Services (OES), the risk assessment identifies the natural, human-caused, and technological hazards that have potential impacts on all or portions of the County. Hazard identification, historical occurrences, and risk modeling (where applicable and available for specific hazards) information was collected from multiple sources including, but not limited to:
• Environmental Systems Research Institute (Esri)
• Federal Emergency Management Agency (FEMA)
• National Centers for Environmental Information (NCEI) • National Weather Services (NWS)
• United States Geological Survey (USGS)
• Local repositories
This information was analyzed to assess the risk and vulnerability of people, property, the environment, and the jurisdiction’s essential operations from these hazards. Furthermore, a risk ranking was performed for the hazards of concern described in this Plan. The risk ranking is an important step in developing an action plan, as it allows jurisdictions to compare the risk factors from one hazard to another. That comparison provides critical information to use in selecting hazard mitigation actions and their priorities.

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

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

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

At the fundamental level, consequence is an assessment of the potential impact(s) if the hazard incident actually occurs. In this assessment, the consequence of an event (or the impact) will be interdependent on the following factors:
• Vulnerabilities (i.e., social, physical, and community conditions) • Capabilities and capacities
• Mitigation
Extent + Vulnerability + Impact = Consequence
Consequence x Probability = Total Risk Score
118
2024 Hazard Mitigation Plan
Contra Costa County, California
City of Clayton Annex 94
• Characteristics of the hazard event (i.e., magnitude, scale) The frequency/probability of the hazard is not included in assessing the consequence because without the event, there is no consequence or impact.

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

Table 28 outlines the probability of occurrence factors used in the risk assessment calculations for this Plan. A significant hazard event is defined as any hazard occurrence that directly or indirectly damages structures or infrastructure, impedes normal business operations, and/or is likely to cause serious or fatal injuries.

Table 28. Probability of Occurrence
Probability Description Probability
Factor
High Significant hazard event is likely to occur annually. 3 Medium Significant hazard event is likely to occur within 25 years. 2 Low Significant hazard event is likely to occur within 100 years. 1 Unlikely There is little to no probability of significant occurrence, or the recurrence interval is greater than every 100 years. 0
The assessment of hazard frequency is generally based on past hazard events in the area and professional judgment of local subject matter experts.

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

C.2.1. Extent/Intensity Factor
Extent is defined as the range of anticipated intensities of the identified hazards. This category is most commonly expressed using various scientific scales (e.g., Saffir-Simpson, Enhanced Fujita, Modified Mercalli). Extent/Intensity Factors are hazard-specific and are detailed in each hazard profile. Table 29 outlines the extent/intensity factors used in the risk assessment calculations for this Plan.

Table 29. Extent/Intensity Factor
Probability Description Extent
Factor
High Historical and/or probabilistic models/studies for this hazard indicate the possibility of a high-intensity incident. 3
Medium Historical and/or probabilistic models/studies for this hazard indicate the possibility of a medium-intensity incident. 2
Low Historical and/or probabilistic models/studies for this hazard indicate the possibility of a low-intensity incident. 1
Unlikely Historical and/or probabilistic models/studies for this hazard indicate the possibility of little to no intensity. 0

C.2.2. Catastrophic Factor
The probability that a hazard could be catastrophic. Catastrophes are defined as significant incidents that cause sudden and great harm or destruction. Table 30 outlines the catastrophic factors used in the risk assessment calculations for this Plan.

Table 30. Catastrophic Factor
Probability Description Extent
Factor
High Catastrophic hazard event is likely to occur at least once in 10 years. 3 Medium Catastrophic hazard event is likely to occur at least once between 11 and 50 years. 2
Low Catastrophic hazard event is likely to occur at least once in 51 or more years.
1 No Impact Virtually no probability that this hazard could be catastrophic. 0 Each category was assigned a weighting factor to reflect its significance, consistent with this typically used for measuring the benefits of hazard mitigation actions – a weighting factor of three (3) was assigned for Extent/Intensity and its potential for Catastrophe.

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

C.3.1. Population Exposure Factor
Population exposure values were assigned based on the percentage of the total population exposed to the hazard event. Table 31 outlines the population exposure factors used in the risk assessment calculations for this Plan.

Table 31. Population Exposure Factor
Probability Description Vulnerability
Factor
High 30% or more of the population is exposed to the hazard. 3 Medium 15% to 29% of the population is exposed to the hazard. 2 Low 14% or less of the population is exposed to the hazard. 1 No Vulnerability None of the population is exposed to the hazard. 0 C.3.2. Property Exposure Factor
Property exposure values were assigned based on the percentage of the total property value exposed to the hazard event. Table 32 outlines the property exposure factors used in the risk assessment calculations for this Plan.

Low 9% or less of the total assessed property value is exposed to a hazard. 1
No Vulnerability None of the total assessed property value is exposed to a hazard. 0 C.3.3. Changes in Development
Changes in development in the past five (5) years have increased or decreased the community’s vulnerability/exposure to the hazard. Table 33 outlines the changes in development factors used in the risk assessment calculations for this Plan.

Table 33. Changes in Development Factor
Probability Description Vulnerability
Factor
High Changes in development have increased the vulnerability/exposure of the community to the hazard by 10% or more. 3
Medium Changes in development have increased the vulnerability/exposure of the community to the hazard between 5% and 9%. 2
Low Changes in development have increased the vulnerability/exposure of the community to the hazard by 4% or less. 1
No Vulnerability Changes in development had no effect and/or have decreased the vulnerability/exposure of the community to the hazard. 0 Each category was assigned a weighting factor to reflect the significance, consistent with those typically used for measuring the benefits of hazard mitigation actions – a weighting factor of three (3) was assigned for Population Exposure, and a weighting factor of one (1) was assigned for Property Exposed and Changes in Development.

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

C.4.1. Population and Life Safety Factor
Population and life safety values were assigned based on the best available data (historical and probabilistic) for people vulnerable to the hazard event and whether the affected population is likely to experience adverse impacts from the hazard incident. Table 34 outlines the population and life safety factors used in the risk assessment calculations for this Plan. 121

No Impact Populations exposed to this hazard are not likely to experience significant adverse impacts. 0
C.4.2. Underserved/Equity Factor
Underserved/equity values were assigned based on the best available data for underserved populations vulnerable to the hazard event and whether the affected population is likely to experience adverse/disproportionate impacts from the hazard incident resulting in greater disparity in equity. Table 35 outlines the underserved/equity factors used in the risk assessment calculations for this Plan.

2 Low
Underserved populations exposed to the hazard are likely to experience minimal adverse/disproportionate impacts, such as ambulatory injuries.
1 No Impact Underserved populations exposed to the hazard are not likely to experience significant adverse/disproportionate impacts. 0 C.4.3. Property Damage Factor
Property damage values were assigned based on the expected total property damage incurred from a hazard incident. It is important to note that values represent estimates of the loss from a major incident based on historical data or probabilistic models/studies. Table 36 outlines the property damage factors used in the risk assessment calculations for this Plan.

APPENDIX E. PLAN ADOPTION
[Placeholder for adoption documentation after State and FEMA Approval] 146
TO: CLAYTON CITY COUNCIL
FROM: Dennis Bozanich
DATE: October 21, 2025
SUBJECT: Consider Adopting Resolution 38-2025 of the City Council of the City of Clayton Appointing Both a Board Member and an Alternative Board Member to the Municipal Pooling Authority of Northern California Board of Directors Agenda Item: 4.d

STAFF REPORT

RECOMMENDATION
Adopt a Resolution appointing both a Board Member and an Alternative Board Member to the Municipal Pooling Authority (MPA) of Northern California Board of Directors.

BACKGROUND
On December 5, 1995, the City of Clayton adopted a resolution repealing resolution 72-91, reaffirming designation of a Board Member and designating an alternative board member to what was formally known as the Contra Costa Municipal Risk Management Authority, now known as the Municipal Pooling Authority of Northern California (MPA).

On June 4, 2024, the City of Clayton removed the title “Assistant to the City Manager/Human Resources Director” from their position list and replaced the position with “Assistant City Manager/Administrative Services Director”.

DISCUSSION
The current MPA agreement states that the Board Member appointed for the City of Clayton is the City’s City Manager and the alternate is listed as the Assistant City Manager. Earlier this year the city eliminated the position of Assistant City Manager and created the Administrative Services Director. The “Administrative Services Director”, will be the Board Member representing the City of Clayton and the alternate Board Member shall be the position of “City Manager."
CEQA
Adopting this resolution is an administrative action that is exempt from CEQA.

FISCAL IMPACT
By approving this action, there is no fiscal impact.

TO: CLAYTON CITY COUNCIL
FROM: Dennis Bozanich
DATE: October 21, 2025
SUBJECT: Report on the Annual Update of the Master Fee Schedule and Improvement Plan
Agenda Item: 4.f

STAFF REPORT

RECOMMENDATION
Staff recommend that the Council receive this report on the update to the City’s Master Fee Schedule for new permits, use fees and facility reservations.

BACKGROUND
The City of Clayton’s Master Fee Schedule was adopted on August 15, 2023 (Resolution 49- 2023.) The Master Fee Schedule includes various fees for Administrative, Police Service, Zoning and Building Permits, Special Event and Facility Use Fees. The adopted Master Fee Schedule includes a provision to update the fees annually based on the Consumer Price Index.

DISCUSSION
Current Fee Increase:

The adopted Master Fee Schedule includes a provision to update all the included fees on an annual basis. The updates are to be made, “based on the annual Consumer Price Index (CPI) Change for ‘All Items’ April to April year, San Francisco Bay Area Average CPI.

Earlier this year, fees were increased by 3.8% for April 2023 to April 2024.

Staff referred to the Bureau of Labor Statistics report dated September 11, 2025, and identified that the Index had increased by 1.3% from April 2024 to April 2025.

Future Updates to the Master Fee Schedule
In the coming year, staff will perform various analysis to determine if fees need to be raised beyond CPI to cover costs of performing work and maintaining the facilities.

Some staff assumptions and actions so far for your information:

Staff have rounded up the draft fees to the next whole dollar Staff have not changed the salaries of staff.

Staff have changed deposit amounts to include credit card fees Staff have added a column to show credit card fees. Those items that are exempt from 154
credit card fees have a note in the credit card column stating their exemption Staff will make organizational updates that will make the fee schedule more user friendly and will include previously excluded items.

Staff will continue to analyze the cost of performing various work, and will propose future changes if the findings show the need for significant increase Staff is working with the police department and the planning department on how to best implement administrative citations that are already included in the municipal code (Municipal Codes Chapters 1.14 – General Provisions, 1.18 – Administrative Citations,

1.20 – General Penalty, 1.22 - Enforcement Officers and 11.04 – Parks provide for the issuing of permits)
CEQA
Updating the Master Fee Schedule is an administrative action that is exempt from CEQA.

FISCAL IMPACT
The increase due to CPI is minimal at this time. Once the cost analysis is completed, the fiscal impact will be included in a future staff report. We anticipate presenting our findings February 9th to the budget and audit committee, and February 17th to City Council. 155

TO: CLAYTON CITY COUNCIL
FROM: Kris Lofthus, City Manager
DATE: October 21, 2025
SUBJECT: Consider Adopting Resolution 39-2025 Approving the Job Description of Community Services Coordinator, Resolution 40-2025 Amending the Miscellaneous Memorandum of Understanding (MOU) related to the Community Services Coordinator, and Resolution 41-2025 Amending Clayton’s Salary Schedule Effective October 21, 2025 to include the Community Services Coordinator, in Conformance with CalPERS Requirements to Provide a Publicly Available Salary Schedule Agenda Item: 8.a

STAFF REPORT

RECOMMENDATION
Staff recommends that the City Council adopt three Resolutions for:

1. Approving the job description of the Community Services Coordinator (Resolution 39- 2025)

2. Approving an amendment to the Memorandum of Understanding for the Miscellaneous Employees Bargaining Unit (Resolution 40-2025)

3. Adopting the City of Clayton’s Salary Schedule Effective October 21, 2025, in Conformance with CalPERS requirements to provide a publicly available salary (Resolution 41-2025)

BACKGROUND
At the January 21, 2025 City Council meeting, the City Council authorized the addition of an Administrative Clerk position. While the position was subsequently filled, it became vacant in September of this year. Upon review, the City Manager has determined that the Administrative Clerk role is not the most critical operational need at this time.

Instead, there is an identified need for a Community Services Coordinator to support the planning and execution of special events, collaborate with community-based organizations, and expand opportunities for additional City-sponsored programming. The responsibilities previously assigned to the Administrative Clerk can be effectively absorbed by existing staff and the newly proposed Community Services Coordinator position. 168

ANALYSIS
The establishment of the Community Services Coordinator position represents a strategic and forward-thinking step in supporting and enhancing the City of Clayton’s commitment to community engagement. This role is designed to provide dedicated leadership and coordination for the City's current calendar of community events, ensuring they are executed efficiently, inclusively, and with a high level of quality.

In addition to managing existing events, the Community Services Coordinator will be responsible for identifying opportunities to expand and diversify the City's events in alignment with community interests and emerging needs. By proactively assessing gaps in programming and exploring innovative event concepts, this role will help to broaden Clayton’s appeal, strengthen neighborhood connections, and enhance the overall quality of life for residents.

A key function of the position will be to serve as a central point of contact for collaboration with existing community-based organizations. The Coordinator will support these partners in the planning and execution of their events, offering resources, guidance, and logistical support as needed. Furthermore, the role will actively seek to build relationships with new and diverse community groups that may be interested in organizing events, helping to foster a more inclusive and vibrant community culture.

Ultimately, the Community Services Coordinator will play a vital role in shaping the City’s public programming, ensuring that community events are not only well-organized and impactful, but also reflective of the diverse voices and interests of Clayton's residents.

This change will result in significant improvements in operational efficiency and customer service, especially for residents, developers, and business owners who interact frequently with the city. The Community Services Coordinator will also be the central figure to communicate with the various departments to ensure readiness for the day of the event. goals are accomplished in a timely and consistent manner.

Community events do more than bring people together, they fuel local economies and spark lasting growth. Whether it’s a street fair, cultural festival, or farmers market, these gatherings generate spending, create jobs, and attract new opportunities to a city. Visitors spend money on food, shopping, boosting revenue for local restaurants, hotels, and shops. At the same time, events create temporary opportunities for jobs, from security to setup, and clean up positions.

Local businesses benefit from increased foot traffic and exposure. Community events provide entrepreneurs and home-based businesses and opportunity to launch or test new products, reach new audiences, which lead to business growth and innovation. In some cases, events 169
even inspire new business models, like food trucks or pop-up shops. Larger events can also put a city on the map, attracting tourists and building a lasting reputation.

Perhaps most importantly, community events build civic pride. They make people feel more connected to their city, encouraging them to spend locally and support community development. In short, community events are powerful economic engines sparking spending, attracting visitors, creating jobs, and building a stronger, more vibrant city for everyone.

Approval of this operational structure will leave the Administrative Clerk on the salary scale and Miscellaneous Employee MOU, but this position would be unfunded. The Community Services Coordinator will be added to both the salary schedule and the Miscellaneous Employee MOU. The updated positions within the MOU would be:

Administrative Clerk
Community Development Technician
Community Services Coordinator
Senior Maintenance Worker
Maintenance Worker II
Maintenance Worker I
Police Administrative Clerk
Police Office Coordinator
This action will also cause a need for an amendment to the currently adopted salary schedule. When amendments are made to the salary schedule, the City Council must adopt those amendments by resolution to keep aligning with requirements set by the California Public Employees’ Retirement System (CalPERS), the City must ensure that employee compensation data, including base salaries and any forms of special compensation, is formally recognized and publicly accessible. This is a critical step in ensuring that earnable income is accurately reported and used in the calculation of retirement benefits. To this end, the City of Clayton’s Salary Schedule must be formally adopted by the City Council during a publicly noticed meeting. In addition to the adoption of the salary schedule itself, all relevant documentation, including individual pay rates and special compensation details, must be made available to the public to satisfy transparency and compliance obligations under CalPERS regulations.

CEQA
Adopting these resolutions is an administrative action that is exempt from CEQA.

FISCAL IMPACT
The funding for this position will be the transfer of funds from the existing Administrative Clerk and will show cost savings of $20,000 with the Community Services Coordinator in the current year. In 2026/2027 the increased cost would be a maximum of $13,000 annually based on top step of the Clayton Salary Schedule.

ARTICLE 10: OVERTIME
Section 10.1 Regular Overtime
The City will compensate eligible non-exempt employees for each one-quarter hour (0.25) of overtime worked at the rate of one and one-half times (1.5) the employee's regular rate of 192
pay including applicable FLSA-required compensation. Overtime is defined as hours worked in excess of 40 hours per 7-day work period or hours worked in excess of regularlyscheduled shift (double counting not permitted). Employee working partial or reduced schedules will not be eligible for overtime until their hours worked exceed the regular work hours noted in Article 4. Authorization of the employee's supervisor must be obtained prior to the working of overtime hours, except in emergency situations. Compensation for overtime shall be in the form of cash payment, or if requested by the employee and approved by their supervisor, in the form of compensatory time off (CTO) that shall also accrue at the rate of one and one-half (1.5) times the actual overtime hours worked.

For purposes of calculating overtime and compensatory time, all City-paid vacation, sick, and or CTO leave shall be considered as hours worked.

Section 10.2 Compensatory Time Off
A maximum of one hundred (100) hours of compensatory time off (CTO) may be accrued by each non-exempt employee of this Unit. Compensatory time off may be approved upon written request of the employee filed at least three (3) days in advance with the appropriate supervisor. Employee request to utilize accrued CTO time will be granted within a reasonable time of the request unless granting it would unduly disrupt operations. Accrued unused CTO is compensable on separation of City employment.

ARTICLE 11: BILINGUAL PAY
The City has the sole and exclusive right to determine and designate which Employees, and how many Employees, are eligible to receive bilingual pay of $75.00 per month.

Designated Employees will be required to demonstrate conversational fluency in a language (e.g., Spanish) as determined by the City Manager based on community/public needs and organizational usage. The City may administer a competency test to certify fluency of the Employee in the designated language. Any such certification shall be a condition prior to Employee qualifying for monthly bilingual pay.

TO: CLAYTON CITY COUNCIL
FROM: Dennis Bozanich
DATE: October 21, 2025
SUBJECT: Receive a Report and Provide Direction to Staff on Future Revenue Options – Financial and Service Needs Impacting the City’s Long-Term Budget Deficit - Part Three
Agenda Item: 8.b

STAFF REPORT

RECOMMENDATION
Staff recommends that the City Council:

1. Receive this report and presentation regarding future revenue options to address identified long-term fiscal needs.

2. Provide direction to staff on preferred revenue mechanisms for further analysis and potential placement on a future ballot measure.

3. Direct staff to return to the City Council on November 18, 2025, with additional information and refined options consistent with Council feedback.

BACKGROUND
On August 19, 2025, the City Council received an initial overview of Clayton’s short- and longterm financial needs and potential revenue sources to sustain essential municipal operations.

At that time, staff identified four major areas of need and six possible revenue mechanisms for Council consideration.

On September 21, 2025, staff returned with additional detail on three specific areas of need:

Closing the structural budget gap, estimated at $700,000 in FY 2027 and rising to $1.1 million annually by FY 2036–37.

Maintaining and improving infrastructure, including pavement condition, sidewalk repairs, and facility improvements, with an estimated annual cost of $2.3 million to $2.94 million over the forecast period.

Supporting employee recruitment and retention, with compensation levels currently averaging 85% of the median for comparable Bay Area cities, requiring an estimated $99,000 in FY 2027 increasing to $128,000 in FY 2036–37. 197
Council directed staff to integrate these fiscal and operational needs with previously identified aspirational goals and to provide a more detailed evaluation of potential revenue mechanisms.

ANALYSIS
Fiscal Outlook
Clayton’s ten-year financial projection demonstrates a widening structural gap between General Fund revenues and expenditures under current conditions. Even with moderate economic growth assumptions, expenditures are projected to outpace revenues by over $1 million annually by FY 2036–37, primarily due to increased personnel, contract, and infrastructure maintenance costs. Without new revenue, service levels, infrastructure quality, and staffing competitiveness will continue to decline.

Identified Financial Needs
Staff’s projection analysis applies a 2.5% annual inflation factor to reflect standard cost escalation. The estimated cumulative annual need—including infrastructure investment, competitive compensation, and operational enhancements—ranges from $3.2 million in FY 2027 to over $4.1 million by FY 2037.

Priority areas include:

Street and sidewalk maintenance (maintaining PCI of ~73 with routine sealing, patching, and replacement).

Public facility and park improvements beyond Landscape Maintenance District boundaries.

Technology and operational efficiency projects, such as records digitization, ecommerce, and website accessibility.

Potential Revenue Options
Six primary mechanisms were reviewed for feasibility and potential yield:

Parcel Tax – Estimated $1.7M to $3.9M annually depending on rate ($400–$800 per parcel). Requires two-thirds voter approval.

Citywide Parcel Assessment – Could generate comparable revenues if supported by a property-owner weighted vote; must meet benefit nexus requirements.

Documentary Transfer Tax – Would generate $60,000 to $825,000 annually depending on transaction volume; requires majority voter approval.

Sales Tax (Transactions & Use Tax) – A 1.0% add-on could yield approximately $1.0M annually based on HdL estimates; requires majority approval for a general tax or two-thirds for a special tax.

Utility Users Tax (UUT) – A 3% UUT on telecommunications, electricity, gas, and water use would generate approximately $1.0M annually; voter approval required. 198
Cannabis Development Agreement (DA) – Could produce $500,000 to $750,000 annually through negotiated revenue-sharing terms; requires lifting the City’s existing prohibition and entering a formal agreement.

Next Steps
If the Council wishes to pursue one or more revenue options for a November 2026 ballot, staff will prepare detailed timelines and procedural steps for Council consideration. Public engagement, fiscal modeling, and legal review would need to begin in early 2026 to stay on schedule.

Clayton faces long-term structural fiscal challenges that cannot be resolved through expenditure reductions alone. Establishing a stable, locally controlled revenue source is essential to maintaining public safety, infrastructure, and community quality of life.

infrastructure maintenance and
development that they can afford
• Reframing the aspirational goal as
X number of dollars to invest in
infrastructure may be a benefit

TO: CLAYTON CITY COUNCIL
FROM: Kris Lofthus, City Manager
DATE: October 21, 2025
SUBJECT: Consider Adopting Resolution 42-2025 Approving the Selected Updated City of Clayton Logo
Agenda Item: 8.c

STAFF REPORT

RECOMMENDATION
Staff recommends that the City Council adopt a Resolution a pproving the selected updated City of Clayton logo.

BACKGROUND
The current City of Clayton logo is difficult to see clearly, especially in digital formats and smaller sizes, which makes it less effective for modern communication needs. Its intricate design and lack of contrast can make it hard to distinguish, particularly on websites, social media, and mobile devices. In an era where clear, recognizable branding is essential, the logo should be updated to reflect a more modern, simplified, and visually accessible design. A refreshed logo would not only enhance visibility but also better represent the city's growth and forward-thinking identity.

ANALYSIS
City logos play a vital role in shaping the identity and perception of a place like Clayton. A strong, well-designed logo serves as a visual symbol of Clayton’s values, character, and community spirit. It helps establish a clear and recognizable brand that reflects what makes Clayton unique — whether that's its rich history, welcoming neighborhoods, thriving local economy, or commitment to growth and innovation. A thoughtful city logo can boost tourism, attract new residents and businesses, and strengthen civic pride among the people who call Clayton home. It also ensures visual consistency across city communications — from websites and signage to social media and official documents — reinforcing a sense of professionalism and unity. Ultimately, a city logo for Clayton is more than just a design; it’s a powerful tool for telling the city’s story, promoting its strengths, and building a connected, forward-looking.

CEQA
Adopting these resolutions is an administrative action that is exempt from CEQA. 217

FISCAL IMPACT
The cost for implementing a change from the current logo would be the applied expenses in new marketing materials such as banners, table coverings, and light pole displays. This is estimated to be approximately $7,500.
