CITY COUNCIL STAFF REPORT
TO: Honorable Mayor and City Council DATE: September 26, 2022 FROM: Matthew Bronson, City Manager
PREPARED BY: Bruce Buckingham, Community Development Director A. Rafael Castillo, AICP, Senior Planner
SUBJECT: Certification of a Negative Declaration and Adoption of Updated General Plan Safety Element
RECOMMENDATION
Adopt Resolutions to certify the Negative Declaration (SCH 2022080144) and adopt the update of the General Plan Safety Element.
BACKGROUND
A city’s General Plan is defined as a comprehensive, long-term plan for the physical development of a city. All cities in California are required to have a General Plan that includes the following seven elements shown below along with the year that the element was adopted or last updated:
• Land Use (2022)
• Circulation (2005)
• Housing (2020)
• Conservation and Open Space (2020)
• Safety (2000)
• Noise (1993)
In addition to the required elements, the City has a Parks and Recreation Element (2005), which is not a required element of the General Plan. The elements of a General Plan should be internally consistent and updated where needed. As part of the FY 2018-19 budget, the Council indicated the need to update the most outdated General Plan elements. The Conservation, Open Space, and Housing Elements were updated in 2020 and the Land Use Element was updated earlier this year as part of a major Development Code update. The City contracted with Rincon Consultants to prepare the Safety Element using the technical studies that were completed as part of the 2019 County of San Luis Obispo Local Hazard Mitigation Plan.
The purpose of the Safety Element is to include safety considerations in the planning and decision-making process by establishing policies related to future development that will minimize the risk of personal injury, loss of life, property damage, and environmental damage associated with natural and human-made hazards. The existing Safety Element covers the following topic areas: Seismic and Geological Hazards, Flood Hazards, Fire Hazards, Airport Hazards, Public Safety and Emergency Management, and Hazardous Materials.
Agenda Item No. 12
Staff Report: General Plan Amendment – 2022 Safety Element Update Page 2 September 26, 2022
The proposed Safety Element update brings the General Plan into compliance with current State law which requires the City to review, and update as needed, the Safety Element every eight years, concurrent with the City’s adoption of either the General Plan Housing Element or the Local Hazard Mitigation Plan. The City adopted its current Housing Element in 2020 with certification by the State Housing and Community Development, therefore, the Safety Element is required to be updated.
At its September 6, 2022 meeting, the Planning Commission recommended to the City Council approval of the General Plan Amendment to the Safety Element as presented on a 5-0 vote.
There were no comments received from the public.
New State Law Requirements
Government Code Section 65302(g) requires the City to identify and update information related to seismic and geologic hazards, evacuation routes, flood hazards, and fire hazards with each update. Senate Bill (SB) 379 (approved in 2015) requires that the 2022 Safety Element update include a set of goals, policies, and objectives based on a vulnerability assessment that identifies the risks that climate change poses to the local jurisdiction and the geographic areas at risk from climate change impacts. Assembly Bill (AB) 747 and SB 99 require local agencies to identify evacuation routes and evaluate their capacity, safety, and viability under a range of emergency scenarios and identify residential developments in hazard areas that do not have at least two emergency evacuation routes.
Vulnerability Assessment
Municipalities are required by law to conduct vulnerability assessments as part of their long-range public safety planning efforts and to prepare policies that will protect against harm caused by climate change. SB 379, Climate Adaptation and Resiliency Strategies (2015), requires the safety elements to be reviewed and updated to include climate adaptation and resiliency strategies. The vulnerability assessment is a technical study prepared in accordance with State guidelines, which identifies how the effects of climate change and related hazard events could be harmful to the community, including to the people, buildings and infrastructure, ecosystems, economic drivers, and key services. It also identifies the natural hazards climate change may exacerbate, the damage that these hazards may cause to people and community assets, and the ability of people and assets to effectively resist and recover from these hazards. The Safety Element update includes the required vulnerability assessment and addresses vulnerability related to temperature changes including extreme heat, precipitation events (drought/floods), coastal storms, coastal erosion, and sea level rise.
Overview of 2022 Safety Element Update
The 2022 Safety Element update addresses the following items:
Introduction/Setting/Regional Plans
This section outlines the setting of the city and includes a brief overview of other plans that have been created that work in tandem with the Safety Element including the Hazard Mitigation Plan, San Luis Obispo Urban Water Management Plan, and the County Emergency Operations Plan.
Critical Infrastructure
This section identifies critical infrastructure and facilities within the city including major highways such as State Highway 1, U.S. Highway 101, schools, and other buildings and infrastructure. In Staff Report: General Plan Amendment – 2022 Safety Element Update Page 3 September 26, 2022
addition to the mapping of these identified items, there is an overview of the current water demand within the city.
Public Safety and Emergency Preparedness
The Public Safety and Emergency Management section includes updates that meet the regulatory requirements for Government Code Section 65302(g)(1). Also included within the Public Safety and Emergency Management section is the identification and mapping of residential developments located in hazard-prone areas that lack at least two evacuation routes, pursuant to SB 99 (codified by Government Code Section 65302(g)(5)).
Hazards of Concern
This section details potential hazards for Grover Beach. Those include the following:
• Seismic Hazards
• Liquefaction
• Flooding
• Dam Inundation
• Tsunami and Seiche Hazards
• Wildland and Urban Fires
• Hazardous Materials
Each section includes a brief description of the hazard and how it may affect residents and businesses within the city. Previously completed maps have been updated with information from the City’s consultant for consistency with new state laws.
Climate Change Vulnerability Assessment
As mentioned earlier, SB 379 Climate Adaptation and Resiliency Strategies (2015) requires the Safety Elements of General Plans to include climate adaptation and resiliency strategies. The 2022 Safety Element update includes the following information to meet this requirement:
• Vulnerability assessment that identifies the risks that climate change poses to the local jurisdiction and the geographic areas at risk from climate change impacts. • Set of adaptation and resilience goals, policies, and objectives based on the information specified in the vulnerability assessment.
• Set of feasible implementation measures designed to carry out the goals, policies, and objectives.
The assessment includes projected climate impacts that may affect the city in the future including average temperature change, extreme heat events, drought, super storm events, erosion, sea level rise, and wildfires.
Based on the analysis, the Safety Element concludes that the City will experience higher average maximum temperatures, more severe storms, increases in extreme heat events, extended drought conditions, and increasing wildfire risk and associated air quality impacts. Extensive impacts from sea-level rise are not anticipated in the near future. In addition, the city is susceptible to the “heat island” effect, which relates to urbanized areas that experience higher temperatures than the edges of the city.
Goals, Policies and Implementation Measures
This section updates the previous goals, policies, and implementation measures for the Safety Element. Many of the implementation measures are carry overs that City staff is currently performing or will begin to perform such as outreach to neighborhoods for emergency preparedness (Five Cities Fire Authority) through grants that were recently received.
Staff Report: General Plan Amendment – 2022 Safety Element Update Page 4 September 26, 2022
Environmental Review
Rincon Consultants, the City’s consultant, has prepared a draft Initial Study and Negative Declaration in compliance with the California Environmental Quality Act (CEQA) and no comments have been received to date. The Negative Declaration concluded that the proposed General Plan Amendment (2022 Safety Element Update) would not have a significant impact on the environment (reference Attachment 1 Exhibit A).
Tribal Consultation
The City conducted Native American consultation consistent with Senate Bill 18 and Assembly Bill 52 for the project to identify potential concerns or issues associated with Native American cultural resources within the project vicinity. The City mailed consultation letters to nine Native American groups and individuals in June and received no comments requesting consultation from local Native American nations.

Government Code Section 65302 requires that a city’s general plan include the following elements:
land use, circulation, housing, conservation, open space, noise, safety, and environmental justice.
The goal of the safety element is to reduce the potential short and long-term risk of death, injuries, property damage, and economic and social dislocation resulting from fires, floods, droughts, earthquakes, landslides, climate change, and other hazards (Governor’s Office of Planning and City of Grover Beach
General Plan Safety Element Update
2 Research 2017). In 2019, City staff to begin updates of the City’s existing General Plan Safety Element for consistency with newly enacted State laws.
The Safety Element evaluates potential risks to Grover Beach by addressing the following topics:
▪ Critical Facilities and Infrastructure (refer to Figure 2) ▪ Peak Load Water Demand
▪ Public Safety Services, Emergency Preparedness, and Emergency Evacuation ▪ Seismic and Geologic Hazards
▪ Flood Hazards
▪ Wildland and Urban Fire Hazards
▪ Hazardous Materials
▪ Climate Change
The Safety Element update includes the following components:
▪ Hazards Assessment: A discussion of the city’s hazards and safety characteristics along with growth and climate change projection for Southern California, and current potential hazards in the city.
▪ Safety and Hazard Mapping: Mapping of unreasonable risks associated with the effects of seismically induced surface rupture, groundshaking, ground failure, tsunami, seiche, and dam failure, slope instability leading to the mudslides and landslides, subsidence; liquefaction, and other seismic hazards, flooding, and wildland and urban wildfires, and information and mapping related to evacuation routes, military installation, peak-load water supple requirements, and minimum road widths and clearances around structures, as those items relate to identified fire and geologic hazards.
▪ Climate Change Vulnerability Assessment: Information regarding flood hazards, wildfire hazards, climate change vulnerabilities, and potential related risks. ▪ Goals, Policies, and Implementation: A description of the goals and policies of the Safety Element, a list of programs that will help achieve these goals and policies, and summary of hazard mitigation, resiliency, adaptation, and emergency response and evacuation objectives, along with the agency responsible for implementing the program.
8. Surrounding Land Uses and Setting
The city includes a sandy beach backed by low sand dunes runs along the western border. The city is relatively flat with low rolling hills along the northern portion of the city boundary. The climate is similar to a Mediterranean climate, with long, dry, and mild summers followed by a modest wet season during the winter months.
Grover Beach is composed of a diverse collection of neighborhoods interconnected by a grid system of streets. Land use within the city is generally characterized by suburban residential uses, with retail and commercial uses along Grand Avenue. There are also limited industrial uses along Front Street and Fourth Street. The street pattern, the abundance of small neighborhood businesses, and the proximity of housing to the commercial corridor formed along Grand Avenue, make neighborhoods in the city walkable.

Scenic vistas are typically categorized as either panoramic views (which provide visual access to a large geographic area) or focal views (visual access to a particular object, scene, setting, or feature of interest). In Grover Beach, scenic resources and vistas include views of open spaces (i.e., beaches, coastal dunes, rolling hills, and wetlands). The Safety Element update includes goals, policies, and City of Grover Beach
General Plan Safety Element Update
10 programs intended to provide guidance on how to proactively minimize the effects of potential disaster events. The Safety Element update does not approve or facilitate any specific development, nor does it grant development entitlements. The Safety Element would not result in any change to the City’s existing development review policies, which enable the City to evaluate whether new development substantially degrades the visual environment of a particular site or its surroundings.
Moreover, individual developments would be subject to project-specific CEQA review, including review of a project’s effect on the visual character and quality of the area. The Safety Element update would not result in a physical change to the environment, and therefore, would not have a substantial adverse effect on a scenic vista, substantially damage scenic resources within a state scenic highway, substantially degrade the existing visual character or quality of public views of the site and its surroundings, nor create a new source of substantial light or glare. No impacts associated with aesthetics would occur.

One 40-acre property on the southern boundary of the city remains in agricultural operation. This property is zoned Urban Reserve. No other areas in the city contain soils that are suitable for productive agricultural uses. Grover Beach does not contain any forest land, timberland, or land under Williamson Act contract.
The Safety Element update includes goals, policies, and programs intended to provide guidance on how to proactively minimize the effects of potential disaster events. The Safety Element update does not approve or facilitate any specific development, nor does it grant development entitlements. The Safety Element update would not result in any changes to the single property in agricultural production. Moreover, individual developments would be subject to project-specific CEQA review, which would evaluate potential impacts related to the conversion of agricultural land to non-agricultural use. The Safety Element update would not result in a physical change to the environment, and therefore, would not result in conflicts with existing zoning for agricultural uses or existing Williamson Act contracts. The Safety Element update would not result in the loss or conversion of forest land, timberland, or agricultural resources. No impacts associated with agriculture and forestry resources would occur.

Grover Beach lies within the South Central Coast Air Basin, and air quality in the city is monitored by the San Luis Obispo County Air Pollution Control District (SLOCAPCD) and the California Air Resources Board (CARB). SLOCAPCD and CARB maintain ten air quality monitoring stations in San Luis Obispo County, including one station in Grover Beach. These monitoring stations record the ambient pollutant levels for ozone (O3), particulate matter (PM10), nitrogen oxides (NOX), sulfur oxides (SOX), and carbon monoxide (CO). The levels of each of these pollutants are compared to state and federal standards in order to determine compliance. SLOCAPCD reports all monitoring data to a comprehensive national database maintained by the United States Environmental Protection Agency (USEPA).
The Safety Element update includes goals, policies, and programs intended to provide guidance on how to proactively minimize the effects of potential disaster events. These goals, policies, and implementation programs of the Safety Element update would have no effect on the SLOCAPCD’s thresholds of significance for air quality. The Safety Element update does not approve or facilitate any specific development, nor does it grant development entitlements. The Safety Element update would not create physical growth and would not affect air quality beyond what is anticipated in the City of Grover Beach

14 existing General Plan; projects that are consistent with the General Plan would be consistent with applicable air quality management plans since the regional air quality impacts associated with implementation of the General Plan have already been considered in the formulation of the plan.
Moreover, individual developments would be subject to project-specific CEQA review, which would evaluate potential impacts related to air quality. The Safety Element update would not result in a physical change to the environment, and therefore, would not result in a cumulatively considerable net increase of any criteria pollutant, would not expose sensitive receptors to substantial pollutant concentrations, and would not result in other emissions, such as odors. No impacts associated with air quality would occur.

Grover Beach is home to riparian, wetland, coastal strand, coastal sage scrub, and central foredunes vegetation. While much of Grover Beach is developed with urban uses, some areas include sensitive plant and animal species. Existing undeveloped lands provide open space and support habitats that are considered sensitive to the region. Riparian and dune habitat in the city are related to proximity to the Pacific Ocean and Meadow Creek. The beach and Meadow Creek are dominated by native habitats, some of which are sensitive plant communities. The riparian corridor surrounding the eastern branch of Meadow Creek comprises the majority of the open space area in the northeastern portion of the city. The eastern branch of Meadow Creek feeds the Pismo Lake Ecological Reserve, and the western branch passes through Pismo State Beach before meeting Arroyo Grande Creek outside of the city. Native trees are located within the Meadow Creek area, including coast live oak (Quercus agrifolia), western sycamore (Platanus racemosa), black cottonwood (Populus trichocarpa), Fremont cottonwood (Populus fremontii), red willow (Salix laevigata), and arroyo willow (Salix lasiolepis).
The Safety Element update includes goals, policies, and programs intended to provide guidance on how to proactively minimize the effects of potential disaster events. The Safety Element update does not approve or facilitate any specific development, nor does it grant development entitlements. The Safety Element update would not create new residential growth that would result in biological resource impacts beyond that already anticipated by the existing General Plan. Impacts to plant and animal species, sensitive habitat, and other biological resources would be assessed on a project-by-project basis, and mitigation would be required, as appropriate, in conformance with City’s Local Coastal Program (LCP), Development Code, and General Plan, and all applicable U.S.
Army Corps of Engineers, California Department of Fish and Wildlife (CDFW), and U.S. Fish and Wildlife Service (USFWS) guidelines and policies.

The proposed Safety Element updates identifies geologic hazards of concern, including seismic and liquefactions hazards, and includes hazards maps that depict earthquake hazards and liquefaction risks in the city. Grover Beach is in a seismically active region on the central coast of California, and the city is vulnerable to various types of seismic hazards including fault rupture, ground-shaking, and liquefaction. There are several faults within proximity to the city including the Wilmar Avenue fault, the San Andreas fault, and the offshore Hosgri fault. The areas with the highest risk for liquefaction in the event of an earthquake include the western edge of the city along the coastline, including West Grand Avenue, Oceano Dunes Natural Preserve, and the Pismo Beach Golf Course. As noted in the Safety Element update, in most cases these natural processes cannot be prevented; however, the magnitude of destruction resulting from natural geologic hazards can be reduced through planning policies and measures.
The proposed Safety Element update includes goals, policies, and programs intended to provide guidance on how to proactively minimize the effects of potential disaster events related to geologic and seismic hazards, including ground shaking, fault rupture, liquefaction and seismic settlement, and slope instability. The Safety Element update does not approve or facilitate any specific development, nor does it grant development entitlements. As such, the Safety Element update would not facilitate development or other operations that could result in or exacerbate seismic or other risks. Similarly, the Safety Element update would not directly result in or indirectly induce any development or other activities in the city that could destroy unique paleontological or geologic resources. Moreover, individual developments would be subject to project-specific CEQA review, which would evaluate potential impacts related to geology and soils. Individual developments would also be subject to requirements of the California Building Code, which would minimize impacts Environmental Checklist

d. In flood hazard, tsunami, or seiche zones, would the project risk release of pollutants due to project inundation?
Flood hazards in the city are a result of its close proximity to bodies of water. Areas that would most likely be flooded during a major rain or tsunami event include the western boundary of the city limits near the Pacific Ocean and the northernmost city limits along Meadow Creek and Pismo Lake.
Stormwater infrastructure in the city does not always have the capacity to adequately handle stormwater flows, and stormwater flooding occurs in several locations that are associated with the historic Meadow Creek floodplain.
The proposed Safety Element update is a policy document that includes goals, policies, and programs intended to provide guidance on how to proactively minimize the effects of potential disaster events. The Safety Element update does not approve or facilitate any specific development, nor does it grant development entitlements. The Safety Element update would not introduce new development or uses that would alter drainage patterns, place people in a tsunami zone, or otherwise increase risks associated with flooding. Nevertheless, policies and associated implementation programs in the Safety Element update are aimed at minimizing the impacts of flooding hazards in the community and would provide for enhanced stormwater and floodwater management to avoid potential adverse effects of erosion, stormwater runoff, flooding, and inundation. Moreover, individual developments would be subject to project-specific CEQA review, which would evaluate potential impacts related to water quality.

Fire protection for the city is provided by the Five Cities Fire Authority, which also serves the City of Arroyo Grande and the Oceano Community Services District. The Five Cities Fire Authority operates three fire stations with one station located in each of the participating communities (the station in Grover Beach is located at 701 Rockaway Avenue). The City operates its own Police Department, and the police station is located at 711 Rockaway Avenue. The Lucia Mar Unified School District serves Grover Beach and other surrounding communities. Parks and recreation facilities in Grover Beach are operated and managed by the City’s Parks and Recreation Department.
The proposed Safety Element is a policy document that includes goals, policies, and programs intended to provide guidance on how to proactively minimize the effects of potential disaster events. Specifically, the Safety Element update establishes goals, policies, and associated implementation programs that are aimed at minimizing urban fire hazards and facilitating adequate emergency access. The Safety Element update does not approve or facilitate any specific development, nor does it grant development entitlements. The Safety Element update entails no land use changes, and would not add any demand for additional fire, police, school, park, or other public facilities. In addition, as future growth in the city occurs, any needs that arise would be addressed and met as each development is proposed and would be funded through the payment of development fees or project specific mitigation, as appropriate and in accordance with Section 65995(h) of the California Government Code (Senate Bill 50, August 27, 1998). Moreover, individual developments would be subject to project-specific CEQA review, which would evaluate potential impacts related to public services. Because the Safety Element update does not provide new sites for housing or businesses, nor alters existing land use and zoning designations to facilitate development, there would be no impacts associated with public services.

The City’s main water supplies are from groundwater and surface water. Grover Beach obtains its water from four groundwater wells in the Santa Maria Valley Groundwater Basin. Grover Beach receives surface water supply from Lopez Lake , which services as the main water supply for the cities of Arroyo Grande, Pismo Beach, Oceano Community Services District, and the County of San Luis Obispo Public Works Department County Service Area 12. Lopez Lake includes Lopez Reservoir and Dam, Lopez Terminal Reservoir, Lopez Water Treatment Plant, and associated water conveyance and distribution systems. Most of the water consumption in Grover Beach is associated with residential properties.
The San Luis Obispo County Flood Control and Water Conservation District Zone 3 is the wholesale water supplier for the Lopez Project. Zone 3 was created to fund, maintain, and operate Lopez Reservoir for municipal and agricultural water supplies and recreation. The Lopez Reservoir covers an area of about 918 acres and is located primarily within the Arroyo Grande Creek drainage area, consisting of a 67 square mile (43,000 acre) watershed that drains into Lopez Reservoir. According to the San Luis Obispo Council of Government (SLOCOG) report, 2050 Regional Growth Forecast for San Luis Obispo County (2017), the projected water demand in the city is not anticipated to increase over the next 20 to 30 years. The population growth for the city will continue at a modest pace for the next twenty years, growing from an estimated population of 13,550 in 2010 to about 15,000 in 2030, which represents an average annual growth rate of about 0.54 percent.
The City is currently allocated 1,407 Acre Feet per Year (AFY) from the Santa Maria Valley Groundwater Basin and 800 AFY of available imported water from Zone 3. The 2030 supply (a combined 2,207 AFY) is expected to remain the same. San Luis Obispo County’s 2020 UWMP finds that it can meet full service demands of its member agencies, including Grover Beach, with existing supplies from 2025 through 2045 during normal years, single dry year, and multiple dry years.
However, prolonged dry periods may affect the City's imported water supply capacities significantly due to reductions in Zone 3’s storage reservoirs resulting from increases in regional demand (County of San Luis Obispo 2020).
Grover Beach, along with other entities, are participating in the Central Coast Blue Project, a proposed regional recycled water project in the initial planning and design phase that is intended to develop a sustainable water supply and help protect the Santa Maria Groundwater Basin from the risk of seawater intrusion and extended periods of drought. This project aims to upgrade the Pismo Beach Wastewater Treatment Plant (WWTP) and the South San Luis Obispo County Sanitation District WWTPs with advanced methods of water treatment including microfiltration / ultrafiltration, reverse osmosis, and ultraviolet disinfection with advanced oxidation (County of San Luis Obispo 2019). The treated water will be used to replenish the Santa Maria Groundwater Basin.
The Safety Element update would establish a policy and an associated implementation program to provide educational materials and programs to support water conservation efforts. Another policy included in the Safety Element update calls for action to pursue diversifying the City’s water supply.
The proposed Safety Element update would not facilitate or allow future development of residential uses that would increase the population in the city, thereby increasing demand on City utilities and service systems. Moreover, individual developments would be subject to project-specific CEQA Environmental Checklist

2 INTRODUCTION
The Safety Element provides Grover Beach residents, decisionmakers, and staff members with knowledge and tools to prepare for natural and human hazards that have the potential to affect the city. Goals, policies, and programs provide guidance on how to proactively mitigate the worst effects of potential disaster events. The Safety Element evaluates potential risks to Grover Beach by addressing the following:
Critical Facilities and Infrastructure
Peak Load Water Demand
Public Safety Services, Emergency Preparedness, and Emergency Evacuation Seismic and Geologic Hazards
Flood Hazards
Wildland and Urban Fire Hazards
Hazardous Materials
Climate Change
SETTING
The city of Grover Beach is a coastal community nestled between the Cities of Arroyo Grande, Pismo Beach, and the community of Oceano. A sandy beach backed by low sand dunes runs along the western border. The city is relatively flat with low rolling hills along the northern portion of the city boundary. The climate is similar to a Mediterranean climate, with long, dry, and mild summers followed by a modest wet season during the winter months.
The city is vulnerable to coastal and urban flooding, dam flooding, earthquakes, liquefaction, wildfires, tsunamis, and hazardous material release. Climate change is anticipated to worsen existing hazards, including flooding and wildfires, and result in a higher frequency of extreme heat days and warm nights. The City of Grover Beach emergency response services consist of the Five Cities Fire Authority and the Grover Beach Police Department. The city obtains its water from Lake Lopez and groundwater wells in the Santa Maria Valley Groundwater Basin.
REGIONAL PLANS
SAN LUIS OBISPO COUNTY MULTI-JURISDICTIONAL HAZARD MITIGATION PLAN (MJHMP) The City of Grover Beach is one of the participating jurisdictions that develops the County of San Luis Obispo Multi-Jurisdictional Hazard Mitigation Plan (MJHMP). The goal of this plan is to arrive at practical, meaningful, attainable, and cost-effective mitigation solutions to reduce vulnerability to hazards and ultimately reduce both human and financial losses from hazard events. The Plan is updated every five years and is prepared in accordance with the Disaster Mitigation Act of 2000 and follows FEMA’s Local Hazard Mitigation Plan Guidance. The MJHMP addresses the following hazards: coastal storm/coastal erosion/sea level rise, dam incidents, drought and water shortage, earthquake, flood, tsunami and seiche, wildfire, and hazardous materials. Annex C of the 2019 MJHMP identifies information specific to Grover Beach.1
SAN LUIS OBISPO COUNTY URBAN WATER MANAGEMENT PLAN
The San Luis Obispo County Flood Control and Water Conservation District prepared the 2020 Urban Water Management Plan (UWMP) for the San Luis Obispo County Flood Control and Water Conservation District (District) Zone 3. Zone 3 funds the operations of the Lopez Project, which includes Lopez Reservoir and Dam, Lopez Terminal Reservoir, Lopez Water Treatment Plant, and the water transmission system, which conveys wholesale water to its contracting retail water agencies, including the City of Grover Beach. The UWMP identifies water supplies necessary to meet existing and future demands. It also evaluates water supply reliability under normal, dry-year, and multiple-dry year conditions. The UWMP includes a water shortage contingency plan that establishes steps the San Luis Obispo County Flood Control and Water Conservation District can take should there be a supply shortage of greater than 50 percent.2

The San Luis Obispo County Emergency Operations Plan (EOP) is the master planning document for emergency management preparedness, response, and recovery activities for the County of San Luis Obispo. Grover Beach is a participating member of the EOP. The EOP directs its participating members to have specific field response actions and other duties associated with responding to emergencies. This plan serves to coordinate participating agencies and ensure consistencies in member strategies to comply with national regulations. In addition to the EOP, the City of Grover Beach utilizes Pulsepoint Alerts for monitoring emergencies for the public and ReadySLO.org for sharing emergency preparedness resources with the public.3
CRITICAL FACILITIES AND INFRASTRUCTURE
The County of San Luis Obispo identified critical and transportation facilities present in Grover Beach in the MJHMP. Figure 1 below shows the Critical and Transportation Facilities in Grover Beach, which include major roadways, community centers, emergency response facilities, major infrastructure, schools, and transit facilities.

PEAK LOAD WATER DEMAND
The city of Grover Beach’s main water supplies are from groundwater and surface water.
Grover Beach obtains its water from four groundwater wells in the Santa Maria Valley Groundwater Basin. Grover Beach also receives surface water supply from Lopez Lake, which serves as the main water supply for the cities of Arroyo Grande, Pismo Beach, Oceano Community Services District, and the County of San Luis Obispo Public Works Department County Service Area 12. The Lopez Lake area includes Lopez Reservoir and Dam, Lopez Terminal Reservoir, Lopez Water Treatment Plant, and associated water conveyance and distribution systems. Most of the water consumption in Grover Beach is associated with residential properties.
The San Luis Obispo County Flood Control and Water Conservation District Zone 3 is the wholesale water supplier for the Lopez Lake and was created to fund, maintain, and operate Lopez Reservoir for municipal and agricultural water supplies and recreation. According to the San Luis Obispo Council of Governments (SLOCOG) report, 2050 Regional Growth Forecast for San Luis Obispo County (2017), the projected water demand in the city of Grover Beach is not anticipated to increase over the next 20 to 30 years.4 The population growth for the city will continue at a modest pace for the next twenty years, growing from an estimated population of 13,550 in 2010 to about 15,000 in 2030, which represents an average annual growth rate of about 0.54 percent.5
The City is currently allocated 1,407 Acre Feet per Year (AFY) from the Santa Maria Valley Groundwater Basin and 800 AFY of available imported water from Zone 3. The 2030 supply (a combined 2,207 AFY) is expected to remain the same. San Luis Obispo County’s 2020 UWMP finds that it can meet full service demands of its member agencies, including Grover Beach, with existing supplies from 2025 through 2045 during normal years, single dry year, and multiple dry years. However, prolonged dry periods may affect the city's imported water supply capacities significantly due to reductions in Zone 3’s storage reservoirs resulting from increases in regional demand.6
Grover Beach along with other entities are participating in the Central Coast Blue Project, a proposed regional recycled water project in the initial planning and design phase that is intended to develop a sustainable water supply and help protect the Santa Maria Groundwater Basin from the risk of seawater intrusion and extended periods of drought. This project aims to upgrade the Pismo Beach Wastewater Treatment Plant (WWTP) and the South San Luis Obispo County Sanitation District WWTPs with advanced methods of water treatment including microfiltration / ultrafiltration, reverse osmosis, and ultraviolet disinfection with advanced oxidation.7 The treated water will be used to replenish the Santa Maria Groundwater Basin. 4 County of San Luis Obispo Multi-Jurisdictional Hazard Mitigation Plan. 2019. https://www.slocounty.ca.gov/Departments/PlanningBuilding/Forms-Documents/Plans-and-Elements/Elements/Local-Hazard-Mitigation-Plan.aspx Accessed 3/4/2022. 5 City of Grover Beach Land Use Element. 2010. https://www.grover.org/380/Land-Use-Element Accessed 7/28/2022. 6 County of San Luis Obispo Urban Water Management Plan. 2020. https://www.slocounty.ca.gov/Departments/PublicWorks/Forms-Documents/Committees-Programs/Flood-Control-Zones/Zone-3-Lopez-Water-Project/Plans-Reports/2020-UrbanWater-Management-Plan.pdf Accessed 3/4/2022. 7 Central Coast Blue Project. https://centralcoastblue.com/our-project/ Accessed 3/14/2022. 6 PUBLIC SAFETY SERVICES AND EMERGENCY PREPAREDNESS

EMERGENCY EVACUATION
The City’s General Plan Safety Element, in accordance with California Government Code Section 65302(g), must identify residential neighborhoods that have fewer than two emergency evacuation routes. Two neighborhoods (see Figure 2 below) have been identified as residential development with fewer than two access points. The two neighborhoods include the Nacimiento neighborhood in the northern portion of the city adjacent to Highway 101 and Le Sage Riviera Mobile Home Park located along the coast and parallel to Highway 1. While the Le Sage Riviera Mobile Home Park has a secondary exit gate to Highway 1, it is considered a single access neighborhood because the unpaved road to the exit may result in a slower evacuation process, and mobile home residents are identified as vulnerable populations. 8 Figure 2 Residential Developments with Limited Evacuation Routes
HAZARDS OF CONCERN
Geologic Hazards
Geologic processes that pose a threat to life, health, property, or infrastructure are considered geologic hazards. Natural geologic hazards that have the potential to affect Grover Beach include seismic hazards and liquefaction. In most cases, these natural processes cannot be prevented; however, the magnitude of destruction resulting from natural geologic hazards can be reduced through planning policies and measures.
Seismic Hazards
Grover Beach is in a seismically active region on the central coast of California as shown in Figure 3. The city is vulnerable to various types of seismic hazards including fault rupture, ground-shaking, and liquefaction. There are several faults within proximity to the city including the Wilmar Avenue fault, which runs along the northern portion of the city limits. The fault is potentially active, with a moderate fault rupture hazard to the city of Grover Beach.9 In addition to the Wilmar Avenue fault several other active and potentially active faults in can produce strong ground-shaking within the city limits.10 The San Andreas fault and the offshore Hosgri fault present the most likely sources of ground-shaking for Grover Beach (located outside Figure 3 map limits).11
Liquefaction Hazards
Geologic hazards associated with ground shaking include liquefaction and ground failure.
Liquefaction takes place when loosely packed, water-logged sediments at or near the ground surface lose their strength in response to strong ground shaking. Liquefaction occurring beneath buildings and other structures can cause major damage during earthquakes.12 As a coastal community, portions of Grover Beach are underlain by layers of unconsolidated sand and young alluvium, which have a high potential to become liquefied during ground-shaking events. Shown in Figure 4 below, the areas with the highest risk for liquefaction in the event of an earthquake include the western edge of the city along the coastline. This area includes West Grand Avenue, Oceano Dunes Natural Preserve, and the Pismo Beach Golf Course. In addition, nearly the entire city is included in a moderate risk for liquefaction posing risks to critical facilities and residents.13

12 Flooding Hazards
Portions of Grover Beach are susceptible to regular flooding in isolated areas caused by heavy rainfall events in FEMA flood zones as shown in Figure 5. Climate change is affecting the behavior of precipitation patterns, resulting in more variable weather patterns and more intense precipitation events, which can increase flood occurrence and severity. A dam failure resulting from a significant earthquake could also cause an extreme flooding event in the city.
Recognizing and preparing for such occurrences allow the City to mitigate associated risks.
Flooding
Grover Beach participates in the Federal Emergency Management Agency’s (FEMA) National Flood Insurance Program. As shown in Figure 5 below, FEMA flood zones are mapped primarily along the coastal areas and northern portions of the city. The map references Flood Insurance Rate Map (FIRM) panels, which is FEMA’s official map that identifies risk premium zones applicable to flood insurance. Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA). SFHAs are defined as areas that will be inundated by a flood event with a 1 percent chance of being equaled or exceeded in any given year. The 1 percent annual chance flood is also referred to as the base flood or 100-year flood, and the areas between the limits of the base flood and the 0.2-percent-annual-chance (or 500- year) flood.14 As discussed in the projected climate impacts sections in this document, more extreme precipitation events are anticipated for Grover Beach. This combined with projected sea level rise will exacerbate flood risk in low-lying coastal areas.
The Arroyo Grande Creek, which splits from Meadow Creek, poses a risk of overtopping and causing Meadow Creek to flood along the western and northern portions of the city. Flooding along Meadow Creek has caused roads to be blocked by flood waters, causing difficulties in access to and egress from portions of the city. The northern and western portions of the city adjacent to Meadow Creek are at the greatest risk of being affected by the 1 percent-annualchance floodplain. The areas at risk of flooding in the northern portions of the city are isolated to an area south of U.S. 101 and north of Nacimiento Avenue where a mobile home subdivision is located. The South Grover Beach and West Grover Beach neighborhoods are also reported to experience flooding issues. Flooding in the western portion of the city is isolated to areas west of the Union Pacific Railroad tracks and areas just east of the railroad tracks in the southwest corner of the city where drainage is trapped by the railroad grade.15 14 FEMA. 2022. https://www.fema.gov/flood-insurance/work-with-nfip/community-status-book Accessed 3/8/2022. 15 County of San Luis Obispo Multi-Jurisdictional Hazard Mitigation Plan. 2019. https://www.slocounty.ca.gov/Departments/Planning-Building/Forms-Documents/Plans-and-Elements/Elements/Local-HazardMitigation-Plan.aspx Accessed 3/4/2022.
Figure 5 Flood Hazards in Grover Beach
14 Dam Inundation
According to the 2019 MJHMP, dam inundation risk from a failure of the Lopez Dam would inundate large portions of the city. The Lopez Dam, an earthen dam located upstream from the community, poses a great risk to Grover Beach if an incident was to occur. Lopez Dam has a capacity of approximately 51,000 acre-feet of water. Failure of the Lopez Dam would follow the Arroyo Grande Creek in a westerly direction approximately 3,000 feet in each direction of the centerline of the creek channel. As seen in Figure 6 below, nearly the entire city south of West Grand Avenue would be inundated in a dam failure event. A failure of the Lopez Dam would also affect Highway 101, impeding or reducing flows of goods, people, and resources into and out of Grover Beach and potentially causing flood damage throughout the entire region. There have been no past dam incidents or failures in Grover Beach. The San Luis Obispo County HMP has identified two critical facilities at risk to dam inundation in Grover Beach: the Train Station and the Front Street Sanitary Sewer Lift Station.
Tsunami and Seiche Hazards
Grover Beach is a coastal community that has the potential to be affected by tsunami hazards as shown in Figure 7 below. Offshore faults and related seismic activity could cause a tsunami event off the city’s coast, even if the faults are thousands of miles away. Grover Beach’s wide beaches and coastal dunes in general provide protection from coastal hazards, although the low-lying areas, including the Le Sage Riviera Mobile Home Park, where Meadow Creek meets the ocean is at moderate risk of tsunami hazards. There are no critical facilities at risk to tsunami inundation. As climate change, and resulting sea level rise continues, the tsunami hazard zone will increasingly extend further inland into the city.

18 Wildland and Urban Fires
California law requires the California Department of Forestry and Fire Protection (CAL FIRE) to assess and identify fire hazard severity zones (FHSZ) across the state and assigns responsibility for each zone to either the State or local jurisdictions16. CAL FIRE high FHSZs are primarily in the northern and western portions of the city, with a very high FHSZ at the northernmost edge parallel to Highway 101, as seen in Figure 8 below.
Regionally, Grover Beach is near other fire zones of high or very high wildfire severity. The city’s proximity to the hills to the north, which are classified as VHFHZs, pose a threat of wildfire spreading into the city. Windstorms can increase the risk of wildland fires in the wildland urban interface (WUI) spreading into the city when strong winds and wildland fires co-occur. Strong winds can increase the speed and reach of flames and carry embers to adjacent areas.
According to the MJHMP, wildfire is a limited hazard for the city of Grover Beach, although the city is vulnerable to worsening air quality and embers from nearby fire occurrences. Figure 9 below shows historical burn areas from previous fires including the Morretti, Gay, Las Pilitas, Campindonico, and SLU-730 fires. None of these fires reached Grover Beach. 16 CAL FIRE identified Fire Hazard Severity Zones are based on factors that influence the likelihood and behavior of fire. Such factors include fire history, existing and potential fuel, predicted flame height, slope of the land and fire weather. There are three levels of hazard: moderate, high, and very high. Urban and wildland areas are treated differently in the model, but it does recognize the influence of embers traveling into urban areas, which is a major cause of the spread of fire.

Hazardous Materials
The California Government Office of Emergency Services (Cal OES) Warning Center reports 21 hazardous materials incidents in Grover Beach from 1994 through October 24, 2018. This likely excludes a large number of unreported minor spills. This constitutes 1 percent of the hazardous materials incidents reported countywide during the same time frame and averages out to roughly 0.8 incidents per year. According to the GeoTracker, the city has no active clean-up sites and no significant hazardous materials facilities.17 However, Grover Beach sits within the Emergency Planning Zone for the Diablo Canyon Nuclear Power Plant.18
RADIATION HAZARDS
Diablo Canyon Power Plant, which is owned by Pacific Gas and Electric Company (PG&E), has been generating nuclear power since 1985. The plant currently provides electricity to more than
1.6 million homes through two 1,100 megawatt reactors. The plant is near Avila Beach and is surrounded by approximately 12,000 acres of land that are managed by PG&E. Grover Beach is approximately 13 miles from the plant. Although the construction and operation of nuclear power plants are closely monitored and regulated, the potential for accidents exists. Local, State, and Federal agencies, as well as PG&E, have emergency plans in place that will prevent, prepare for, or mitigate the consequences should an accident occur.19 The Diablo Canyon Emergency Planning Zone is divided into 12 Protective Action Zones (PAZ) and a 5 and 10 nautical mile safety zone. PAZs help organize emergency planning and response actions into areas that are familiar to emergency response agencies and the public. If there is a major emergency, residents in a PAZ may be directed to take protective actions, such as evacuation or shelter in place.20In the event of a nuclear incident, Grover Beach is identified as part of Zone 10 within the Diablo Canyon Nuclear Plant Evacuation. The Diablo Canyon Nuclear Plant is slated for decommissioning with operating licenses set to expire in November 2024 and August 2025.
ELECTROMAGNETIC FIELDS
The Diablo Canyon Power Plant has high voltage transmission lines that span out from the power plant across parts of the county. Electric and magnetic fields are created by high voltage electric transmission lines, distribution lines that bring electricity into structures, and from all common household appliances that use electricity. None of the high voltage transmission lines are located within Grover Beach.
RADON
Radon is a radioactive gas that has no smell, color, or taste. Radon is produced from the natural radioactive decay of uranium, which is found in all rocks and soils. Radon can also be found in water. Radon escapes from the ground into the air, where it decays and produces further 17 State Water Resources Control Board.

As we breathe, these particles are deposited on the cells lining the airways, where they can damage DNA and potentially cause lung cancer. Outdoors, radon quickly dilutes to very low concentrations and is generally not a problem. The average outdoor radon level varies from 5 Bq/m3 to 15 Bq/m3 (Becquerel per cubic meter). However, radon concentrations are higher indoors and in areas with minimal ventilation, with highest levels found in places like mines, caves, and water treatment facilities. In buildings such as homes, schools, offices, radon levels can vary substantially from 10 Bq/m3 to more than 10 000 Bq/m3.
Given the properties of radon, occupants of such buildings could unknowingly be living or working in very high radon levels.21 According to the Department of Conservation, there is low potential for indoor radon in Grover Beach.
HAZARDOUS TREES
Some trees species can be potentially hazardous due to a higher risk of tree damage.
Eucalyptus trees tend to be brittle and have shallow roots. Eucalyptus trees line parts of Highway 1, Front Street, and South 4th Street, and have the potential to succumb to strong winds losing large limbs or even toppling over, causing disruptions and the potential for injury and damages. In addition, pine pitch canker, a disease that can result in the death of pine trees, has been threatening pine tree health in the region.22
OIL PIPELINES
Two crude oil pipelines (12-inch summit line and 8-inch Orcutt line) are located within the city limits. The franchise agreement for these pipelines was continued in 2015 after the City Council adopted a franchise agreement with Phillips 66 Pipeline LLC. Historically, the lines were used to move Santa Maria Crude from the tank farm in Avila Beach to the refinery on the Nipomo Mesa.
AIRPORTS
The community of Oceano has an airport south of Grover Beach. The operating airport has designated hazard zones extending from the end of each active runway. Safety hazards associated with the County’s airport are principally related to the risk of an aircraft accident and are addressed by each airport's land use plan adopted in compliance with Section 21675 of the California Public Utilities Code. Noise occurring at these airports is addressed in the Noise Element.
CLIMATE CHANGE VULNERABILITY ASSESSMENT
Methodology
Climate change adaptation and resilience strategies must be included in the City’s General Plan via its Safety Element in accordance with California Government Code Section 65302(g) (as updated by SB 379). The review and update must consist of the following components:

Safety Element Update 23
1. A vulnerability assessment that identifies the risks climate change poses to the local jurisdiction and the geographic areas at risk from climate change impacts.
2. Set of adaptation and resilience goals, policies, and objectives based on the information specified in the vulnerability assessment.
3. Set of feasible implementation measures designed to carry out the goals, policies, and objectives.
Climate change is driven by the human contribution of certain gases like carbon dioxide and methane into the atmosphere. These gases, commonly known as greenhouse gases or GHGs, absorb and re-emit heat that has been discharged from the earth’s surface. This works to trap heat near the earth’s surface, increasing the natural greenhouse effect. Greenhouse gases from human activities have been collecting in the atmosphere since the 1800s and are warming the climate more and more every year. This rise in average temperatures across the globe affects precipitation patterns, temperature, and ocean water levels. Grover Beach is expected to experience increased temperatures, including longer and more frequent extreme heat events, extreme precipitation events, extended drought and water shortages, coastal storm and sea level rise-related flooding, accelerated rates of coastal erosion, and increased risk of wildfires and associated air quality degradation as a result of climate change.
The Intergovernmental Panel on Climate Change (IPCC), a United Nations subgroup responsible with global advancement and communication of climate change, has established several GHG emissions scenarios used to describe possible future GHG emissions and associated warming. Two of these scenarios are commonly used to compare possible future conditions and have been selected for this assessment, consistent with guidance from Cal OES California Adaptation Planning Guide.23
The Representative Concentration Pathway (RCP) 4.5 represents a “medium emissions” scenario in which emissions peak around 2040 and then decline at the end of the century. This scenario assumes global agreement and implementation of aggressive GHG reduction strategies.
RCP 8.5 represents a “high emissions” scenario in which emissions continue to rise throughout the 21st century.
The State provides the Cal-Adapt tool to local jurisdictions for climate adaptation and resilience planning. Cal-Adapt is a web-based platform that provides climate change projections and climate impact research that are downscaled to the local level based on different GHG scenarios. The projections are based on the extensive body of climate research described in California’s Fourth Climate Change Assessment.24 The Safety Element includes climate change projections for the RCP 4.5 and RCP 8.5 scenarios taken from Cal-Adapt for temperature, precipitation, and wildfire. These climate change projections provide an understanding of possible future climate change impacts and help to prioritize policies to increase community resilience to climate change.
The sea level rise data from Coastal Storm Modeling System (CoSMoS) was used to project sea level rise scenarios in the city. CoSMoS is a dynamic modeling tool developed by U.S. 23 California Office of Emergency Services (OES). 2020. https://www.caloes.ca.gov/HazardMitigationSite/Documents/CAAdaptation-Planning-Guide-FINAL-June-2020-Accessible.pdf Accessed 3/14/2022. 24 California’s Fourth Climate Change Assessment. 2018. https://www.energy.ca.gov/sites/default/files/2019-11/Reg_Report-SUMCCCA4-2018-006_CentralCoast_ADA.pdf Accessed 3/8/2022. 24 Geological Survey to allow more detailed predictions of coastal flooding due to both future sealevel rise and storms integrated with long-term coastal evolution.25 CoSMoS data provides detailed projections for tidal inundation and coastal flood hazards along San Luis Obispo County’s coastline. This data was used by the MJHMP to conduct a GIS analysis of potentially affected critical facilities from a variety of sea level rise scenarios. This modeling is used to illustrate coastal flooding hazardous events under both existing conditions and future sea level rise projections. In this case, three scenarios were used to evaluate the potential impacts on critical facilities as shown in Table 1 below.

Projected Climate Impacts
TEMPERATURE
According to California’s Fourth Climate Change Assessment, average temperatures, both minimum and maximum, are expected to increase in the central coast region. Since 1901, average temperatures across the country have increased, with eight of the top ten warmest years on record having occurred over the past 30 years.26 Average trends are increasing at both the local scale and the global scale.
Compared to the modeled historical 30-year average (1961-1990), the average maximum and minimum temperatures are expected to increase in the coming decades in Grover Beach. The average maximum temperatures under RCP 4.5 are projected to increase by 3.2 degrees Fahrenheit (°F) by mid-century and 4.2°F by the late century. Average maximum temperatures are expected to rise between 4.2°F (RCP 4.5) and 6.7°F (RCP 8.5) by the end of the century.27 In addition, average minimum temperatures are expected to rise similarly, between 4.1°F (RCP
4.5) and 6.7°F (RCP 8.5) by the end of the century as seen in Figure 10 and Figure 11.
Figure 10 shows average maximum temperatures in Grover Beach based on the RCP 4.5 (medium emissions) and RCP 8.5 (high emissions) emissions scenario. The purple line shows high emissions scenario (RCP 8.5), the blue line shows the medium emissions scenario (RCP

Extreme Heat
In addition to warming temperatures, the number of extreme heat days per year is also expected to increase. In Grover Beach an extreme heat day is when the maximum temperature exceeds 88.0°F, which is defined as the 98th percentile value of historical daily maximum/minimum temperatures (from 1961–1990, between April and October) observed at a location. 28 Compared to the modeled historical 30-year average (1961-1990), the annual number of extreme heat days may increase by 5 to 12 days by the end of the century depending on the emissions scenario.29 Figure 12 shows the number of extreme heat days in Grover Beach for the medium and high emissions scenarios.
Figure 12 Extreme Heat Days in Grover Beach
Precipitation
According to California’s Fourth Climate Change Assessment, the Central Coast Region Report (2018), is projected to experience an increase in the number of days each year for which atmospheric river precipitation events result in extreme precipitation. Along the central coast, atmospheric rivers (long and narrow regions in the atmosphere that transport most of the water vapor outside of the tropics) are the dominant drivers of locally extreme rainfall events and are 28 California Energy Commission.

28 associated with most major inland foods in California.30 Estimates project the wettest day of the year to increase up to 35 percent. Model projections suggest that potential changes in average precipitation range between an increase of 3 and 10 inches annually (see Figure 13). However, both wet and dry periods are expected to become more extreme and frequent, leading to overall increased variability in the region and in California. Currently, the region receives approximately 25 to 40 days of precipitation from atmospheric rivers each year. Late-century projections show an increase of approximately a third from current conditions to between 35 and 55 days each year.31
ANNUAL PRECIPITATION
Compared with modeled historical data (1961-1990), mid-century projections predict annual precipitation to increase between 0.1 inches and 0.2 inches by late-century (2070-2099). While average annual precipitation is not expected to change significantly, precipitation will likely fall in more intense storms within a shorter wet season. For much of the state, research suggests that wet years will become wetter and dry years will become drier and will extend for longer stretches of time, increasing the risk of extended drought.32 Annual projected precipitation in Grover Beach is shown in Figure 13 below. 30 California’s Fourth Climate Change Assessment. 2018. https://www.energy.ca.gov/sites/default/files/2019-11/Reg_Report-SUMCCCA4-2018-006_CentralCoast_ADA.pdf Accessed 3/8/2022. 31 County of San Luis Obispo Multi-Jurisdictional Hazard Mitigation Plan. 2019. https://www.slocounty.ca.gov/Departments/Planning-Building/Forms-Documents/Plans-and-Elements/Elements/Local-HazardMitigation-Plan.aspx Accessed 3/4/2022. 32 California’s Fourth Climate Change Assessment. 2018. https://www.energy.ca.gov/sites/default/files/2019-11/Reg_Report-SUMCCCA4-2018-006_CentralCoast_ADA.pdf Accessed 3/8/2022.

30 Figure 14 Maximum 1-day Precipitation in Grover Beach Drought and Water Shortage
According to California’s Climate Adaptation Strategy, climate change is likely to significantly alter California’s future water supply, and therefore, change the way water is managed because of a more limited and varied supply.34 Grover Beach experiences episodic weather and climate patterns resulting in long dry year to multi-year droughts followed by wet years. The 30-year modeled historical average for maximum length dry spells is 132 days. Like the patterns in future precipitation some of the annual variability is obscured within 30-year averages. It is projected that the maximum lengths of consecutive days without precipitation or dry spells, may increase through the end of century. Mid-century projections predict an increase of six days in the RCP4.5 scenario and seven days in the RCP8.5 scenario. By the end of the century, projections predict an increase of eight days (RCP4.5) to 13 days (RCP8.5) as seen in Figure

Coastal Storm, Coastal Erosion, and Sea Level Rise
Grover Beach is a coastal community with a long sandy beach backed by low sand dunes covered with dense vegetation. The sandy beaches provide moderate protection from storm waves. Active erosion of beaches and dunes currently affect low-lying coastal recreation uses, commercial and residential structures.
As part of the 2019 MJHMP planning effort, a sea level rise risk assessment was completed to determine how sea level rise may affect coastal jurisdictions and critical facilities and how coastal flooding might be exacerbated in the future. Shown in Figure 16 below, utilizing data and methods from CoSMos, projections for sea level rise are illustrated at 25cm sea level rise (SLR), 75cm SLR, and 300cm SLR. The city is projected to have minimal impact at 25cm and 75cm SLR scenarios. Once sea levels reach 300cm, according to the MJHMP, several critical facilities, commercial, residential, and industrial properties would experience daily flooding.
Additional properties would be affected or damaged during a 1 percent coastal storm event (See Figure 17).
32 Figure 16 Sea Level Rise (No Flood Event) in Grover Beach Safety Element Update 33
Figure 17 Sea Level Rise (1% Storm Event) in Grover Beach 34 Wildfire and Air Quality
Current scientific models project that California will be affected by increased numbers of forest fires with added intensity due to longer warmer seasons, reduced distribution of biodiversity, lack of moisture, changes in ecosystems, drought impacts (e.g. pest diseases and continued spread of invasive species), and other impacts in coming years. In addition to changes in wildfire behavior, urban development has expanded and is anticipated to grow more, which will increase the potential risk to wildfire exposure.36 Wildfire is a frequent occurrence within the Central Coast region. The last decade saw a series of dramatic fires, each with substantial impacts on ecosystems and human infrastructure. Several of the largest fires in California have occurred within the last 10 years including the Thomas Fire, one of the largest fires in California history. Future projections using statistical models indicate that central California may experience a larger number of wildfires and burned area by the mid-21st century under RCP
8.5. Overall burned area is projected to increase over 30 percent in the RCP 4.5 and more than 35 percent in RCP 8.5 scenarios by mid-century. Overall burned area is projected to increase over 40 percent in the RCP 4.5 and more than 35 percent in RCP 8.5 scenarios by endcentury.37 Many factors affect projected future occurrence of wildfire because of climate change.
There are significant uncertainties associated with the influence of climate change on the future occurrence of wildfire in or near the city.
In addition to the threat of wildfire, air quality can be greatly affected by nearby wildfires. Smoke can cause numerous health effects, from mild eye burning to irritated air ways and even cardiac issues. When smoke levels are high enough even healthy people may experience some of these symptoms.38
VULNERABLE POPULATIONS AND ASSETS
Community members will be affected by climate change to varying degrees depending on their sensitivity to its impacts including populations with access and functional needs, which is defined as community members who need assistance due to any condition (temporary or permanent) that limits their ability to act regardless of a formal diagnosis or specific evaluation.39 Social vulnerabilities can greatly inhibit the adaptive capacity of a community and can be remedied by implementing the Resilience Hubs concept, which are community-serving facilities that have been adapted to support residents before, during, and after a natural hazard event.40 On a larger scale, communities may be more vulnerable because of limited access to financial capital and resources, various institutional barriers, social network limitations, and compromised access to critical infrastructure. Adaptive capacity is largely influenced by governance, management, and institutions, thus making it imperative that adaptive capacity is 36 County of San Luis Obispo Multi-Jurisdictional Hazard Mitigation Plan. 2019. https://www.slocounty.ca.gov/Departments/Planning-Building/Forms-Documents/Plans-and-Elements/Elements/Local-HazardMitigation-Plan.aspx Accessed 3/4/2022. 37 California Energy Commission.

addressed through effective policy implementation. On a more local level, the sensitivity of a community depends more on the specific makeup of the community (i.e., specific populations and assets).
The most likely impacts of climate change that Grover Beach may experience include increases in average maximum temperatures, more severe storms, increases in extreme heat events, extended drought conditions, and increasing wildfire risk and associated air quality impacts.
Extensive impacts from sea-level rise are not anticipated in the near future. In addition, the city is susceptible to the heat island effect, which relates to urbanized areas that experience higher temperatures then the edges of the city.41
Populations
Certain population groups may be disproportionately harmed by the impacts of climate change.
As part of the 2019 MJHMP, San Luis Obispo County identified a social vulnerability index based on the Center for Disease Control’s (CDC) Agency Toxic Substances and Disease Registry (ATSDR) and their Geospatial Research, Analysis & Services Program teams. Grover Beach, along with Oceano, southwestern San Luis Obispo County, southeastern Atascadero, southeastern and western Paso Robles, San Miguel, and the Adelaida region, ranked highest for social vulnerability. The tool groups indicators by the following themes: socioeconomic status, household composition, race/ethnicity/language, and housing/transportation. Grover Beach was identified as high for overall social vulnerability, socioeconomic status, household composition & disability, and housing & transportation themes, and moderate for minority status & language theme.
The California Adaptation Planning Guide (APG) establishes a process for identifying populations groups that are vulnerable to climate change. Based on the APG, the populations most at-risk to climate change that are present in Grover Beach, include:
People experiencing homelessness
Children
Seniors
Outdoor workers
Low-income
Renters
Unemployed
Non-white communities
Non-English speakers
Individuals with impaired health/disabilities
Individuals with educational attainment less than 4 years of college Individuals with no healthcare
Veterans
41 U.S. Environmental Protection Agency (EPA). 2022. https://www.epa.gov/heatislands Accessed 3/22/2022. 36 Single female heads of households
Mobile home communities
These populations were identified using the Office of Environmental Health Hazard Assessment (OEHHA) CalEnviroScreen 4.0 Indicator Maps, California Healthy Places Index tool, and the U.S. Census.42 ,
External factors present in the community that also contribute to climate change vulnerability include high housing cost burden and exposure to poor air quality related to diesel particulate matter. The city experiences widespread housing cost burden. Housing-burdened low-income households are households that are both low income and highly burdened by housings costs.
The city is within the 60th and 80th percentile, which means that it experiences a higher housing cost burden than between 60 and 80 percent of the rest of the state. In addition to housing cost burden, the city experiences widespread exposure to diesel particulate matter. Diesel particulate matter comes from exhaust from trucks, buses, trains, ships and other equipment with diesel engines contains a mixture of gases and solid particles. These particulates are harmful to public health and the largest concentrations are along Highway 1 and Highway 101 in the city. Grover Beach has diesel particulate matter concentrations within the 45th and 52nd percentile, which means it is between 45 and 52 percent higher than the rest of state.43 Residents and businesses rely on various infrastructure and services such as water systems, electricity, natural gas, and roads. These systems and assets are vulnerable to the impacts of climate change, which in turn puts the wellbeing of community members at risk. Those with preexisting and chronic health conditions that rely on services and systems, are particularly vulnerable in situations where hazard events impact access to electricity, food, water supplies, healthcare, sanitary resources, transportation, and communication platforms. To help reduce negative impacts on vulnerable populations and increase adaptive capacity, it is vital that strategies and policies are implemented that ensure continuity of systems and services in the event of climate hazard events.
GOALS, POLICIES, AND IMPLEMENTATION PROGRAMS
Community safety is critical to fostering a healthy and livable environment for residents to thrive and enjoy a good quality of life. Adequate emergency response, hazardous material mitigation, and disaster preparedness are among the major contributors to community safety.
