2025 Urban Water Management Plan
Section 1: Introduction and Lay Description

1.01 Background and Purpose
The California Urban Water Planning Act (Act) requires urban water suppliers that have 3,000 or more service connections or supply 3,000 or more acre-feet (AF) of water per year to develop an Urban Water Management Plan (UWMP or Plan), which is submitted to the California Department of Water Resources (DWR) every five years. No significant changes were made to the Act since the previous UWMP was prepared in 2020, only definitions have been added or updated.

This 2025 UWMP Update has been prepared in accordance with the January 2026 “Urban Water Management Plan Guidebook” (Guidebook) prepared by DWR. The format of the Plan generally follows the recommended organization in Chapter 1.3 of the Guidebook and incorporates the required standardized tables as numbered and shown in the Guidebook and as appropriate for the City’s wholesale and retail operations. Some of the tables are not applicable to the respective systems and are not included as noted in the text.

As noted in the Guidebook, the focus of a UWMP requires addressing the following water planning fundamentals:
 Preparing a detailed look at current and future water use, including assessing available baseline data and examining long-term planning documents like General Plans and Specific Plans.  Analyzing potable and non-potable water supplies, including reviewing water rights and contracts, assessing water deliveries, ascertaining restrictions on water availability under certain regulatory and hydrological conditions, and other opportunities or limitations for each water supply.  Analyzing water supply reliability by integrating the water-use analyses with the water supply analyses to provide a water service reliability picture under normal conditions, single dry year conditions, and five consecutive dry years through at least 2045.  Preparing a realistic Drought Risk Assessment (DRA) by including integrated water supplies and projected water use in a hypothetical five-year drought condition.  Developing an effective Water Shortage Contingency Plan (WSCP) that specifies opportunities to reduce demand and augment supplies under numerous, and even unpredictable, water shortage conditions.

This 2025 UWMP includes both the City of Bakersfield’s (City’s) Municipal Water System (retail) and Wholesale Water System (wholesale). The 2025 UWMP is an update to the 2020 UWMP adopted by the City. However, the 2025 UWMP is considered a stand-alone document.

This 2025 UWMP does not directly address the City’s urban water use objectives (UWUOs) established under the State Water Board’s Making Conservation a California Way of Life Regulation on Urban Water- Use Efficiency Standards, Objectives, and Performance Measures (Making Conservation a California Way of Life regulation) since UWUO compliance is not part of UWMP content requirements. However, continued implementation of demand management measures are anticipated as the City works to achieve compliance with its UWUOs which will result in a reduction in per capita water usage.

1.03 Lay Description - Fundamental Determinations of the UWMP ______________________________________________________________________________________ California Water Code
Each plan shall include a simple lay description of how much water the agency has on a reliable basis, how much it needs for the foreseeable future, what the agency’s strategy is for meeting its water needs, the challenges facing the agency, and any other information necessary to provide a general understanding of the agency’s plan (10630.5). ______________________________________________________________________________________ As detailed in the following sections of this UWMP, the City of Bakersfield’s (City) Municipal Water System and Wholesale Water System have sufficient water supplies to meet the needs of their customers for the next twenty years and beyond. Fundamental determinations in this UWMP are summarized as follows.

Water System Description
The Municipal Water System is a retail water supplier managed by the City’s Water Department and operated under a service contract with California Water Service Company (Cal Water). The service area boundaries for the Municipal Water System include only a portion of the City of Bakersfield. Remaining areas of the City are served by other retail water suppliers. The primary source of supply for the Municipal Water System is groundwater and recharged surface water supplies pumped from City owned wells. This is supplemented by water from surface water treatment plants owned by Cal Water and Kern County Water Agency Improvement District No. 4 (KCWA ID4). In 2025, the City’s Municipal Water System service area consisted of 51,559 municipal connections and it supplied a volume of 46,149 acre-feet of water to its service area.

The City’s Wholesale Water System is operated by the City’s Water Department which oversees the City’s Kern River water rights and water supplies. Kern River water supplies are either delivered to surface water treatment plants for subsequent use by retail water suppliers within the City area or are replenished to the groundwater basin for the benefit of the City and other retail water suppliers through their respective groundwater wells. A volume of 56,406 acre-feet of Kern River surface water was delivered through the Wholesale Water System during 2025.

Water Use Projections
The City has adopted General Plan and Zoning Ordinances which include land use goals, policies, and implementation measures for development. Proposed land uses within the City’s Municipal Water Service Area per the General Plan are similar to current land uses within the City. These primarily consist of City of Bakersfield 1-3
2025 Urban Water Management Plan
residential uses with some commercial, light industrial, schools, and parks. Population growth is anticipated to be about 1.4 percent annually based on historic growth rates and population projections developed by Kern Council of Governments.

The continued implementation of demand management measures to meet the UWUOs established by the State’s Making Conservation a California Way of Life regulation will result in decreasing per capita water use in the future. Water demands in the Municipal Water System service area are projected to total approximately 47,555 acre-feet annually in 2045, which is nearly the same as 2025 water usage. Water demands in the Wholesale Water System for delivery to surface water treatment plants and groundwater recharge are projected to total 100,000 acre-feet annually. The City’s projected water usage estimates are expected to adequately address climate change impacts during the period covered by this UWMP.

Water Supplies and Reliability
The City pumps groundwater and recharged surface water from the Kern County Subbasin of the San Joaquin Valley Groundwater Basin (Groundwater Basin No. 5-22.14) which is currently non-adjudicated. The Kern County Subbasin is designated as critically overdrafted and identified as a high-priority basin in the latest version of Bulletin 118 published by the DWR.

The City is a member of the Kern River Groundwater Sustainability Agency (KRGSA) which was formed in compliance with the Sustainable Groundwater Management Act (SGMA) to cooperatively manage local groundwater in a sustainable manner. The KRGSA subsequently became a participant in the Kern County Subbasin Groundwater Sustainability Plan (KCSGSP), with the intent to coordinate groundwater management throughout the entire 2,800 square mile Subbasin. An Amended KCSGSP was adopted in August 2025 and submitted to the State Water Board and DWR for review.

The KCSGSP includes management actions and proposes projects to maintain the groundwater resource in a sustainable condition under future climate change conditions through the year 2070. As a result of the ongoing management of the groundwater basin, the City’s groundwater and recharged surface water supplies are anticipated to be sufficient to meet its demands for the next 50 years and beyond. The City’s groundwater operations are subject to conformance with the requirements of the KCSGSP.

The Municipal Water System has sufficient redundancy to allow wells and other facilities to be taken offline as needed for maintenance or repairs. The City has installed standby generators at its well facilities so that it can continue to provide water supplies in the event of an electrical power outage. Wellhead groundwater treatment facilities have been installed where necessary to continue providing water supplies that meet current potable water standards. The City will construct new wells or rehabilitate existing wells as required to meet water demands. Groundwater wells will be equipped with wellhead treatment as necessary to remove contaminants that exceed water quality standards. When SWP supplies are not available from KCWA ID4, the City can deliver its Kern River supplies to KCWA ID4 for treatment in place of SWP supplies.

The Wholesale Water System provides groundwater recharge of Kern River water supplies both by transportation through the Kern River and unlined portions of the Carrier Canal and within groundwater replenishment areas such as the City’s 2800 Acres recharge facility, Truxtun Lakes, Aera Park, and the Park at Riverwalk. The Environmental Impact Report (EIR) for the Kern River Flow and Municipal Water Program estimated the City’s Kern River water supplies for both urban use and the City’s fulfillment of various contractual obligations average about 135,000 acre-feet per year. Approximately 100,000 acre-feet of the 135,000 acre-feet is designated for urban use The City has storage rights in Lake Isabella that allows for flexibility in the management of its Kern River supplies.

Water Shortage Contingency Planning
The City’s adopted its 2020 Water Shortage Contingency Plan (WSCP) as a part of its 2020 UWMP. The adopted WSCP provides measures, referred to as response actions, to be implemented in the event of water City of Bakersfield 1-4
2025 Urban Water Management Plan
shortages. The intent of the water conservation measures and progressive restrictions on water use identified in the City’s WSCP are to provide guidance to the City in managing and mitigating anticipated water supply shortages. The structured steps are designed to allow the City to assess its available water supplies and implement appropriate measures in response to actual conditions so that water shortages can be managed efficiently, predictably, and with accountability.

A water shortage condition is defined as when available water supplies are insufficient to meet the normally expected customer demands. Water shortage conditions may be a result of population growth, climate change, drought, catastrophic events, or other water shortage emergencies declared by either the City, State or Federal government.

In accordance with Water Code requirements, there are six standard water shortage levels and response actions defined in the City’s WSCP that increase restrictions on water use in response to increasing levels of water shortage conditions ranging from 10 percent to greater than 50 percent.

The City’s WSCP is a stand-alone document. The response actions and other considerations in the City’s WSCP will be reviewed on a periodic basis to determine the effectiveness of the implementation of the various measures to achieve the desired water demand reductions. Proposed revisions to the WSCP will be submitted to the City Council for adoption.

Demand Management Measures
The City has implemented demand management measures (DMMs) to achieve its water conservation targets. The City partners with Cal Water for the implementation of its Water Conservation Program. Cal Water maintains a Water Conservation Program Coordinator that oversees the water conservation programs available to the City’s Municipal Water System service area customers. The City will continue with the implementation of its existing DMMs and look for ways to improve water use efficiency as it works toward compliance with its established UWUOs.

Section 3: System Description

3.01 General Description
______________________________________________________________________________________ California Water Code
Describe the service area of the supplier (10631(a)).
______________________________________________________________________________________ The City of Bakersfield is located at the southern end of the San Joaquin Valley approximately 100 miles north of the City of Los Angeles. The City is the largest metropolitan area in Kern County and serves as the county seat. The Sierra Nevada mountains are located to the northeast of the City and the Tehachapi Mountains are located to the south.

The City of Bakersfield purchased Kern River assets, including a majority of its water rights, along with canals, land, and the physical water distribution systems for the Ashe Domestic Water Service Area from Tenneco West (Tenneco) on December 22, 1976. The Kern River water rights, canals, and land now comprise the City’s Wholesale Water System. The Ashe Domestic Water Service Area has been expanded over time and now functions as the City’s Municipal Water System.

The boundaries of the City’s Municipal Water System Service Area and the other retail water suppliers serving lands within the City limits are shown on Plate 1. The City’s Municipal Water System Service Area covers approximately 58.62 square miles in the westerly portion of the City limits, as shown on Plates 2 and 3, and provided water service to 51,559 connections in 2025. Service connections within the Municipal Water System are primarily residential with some commercial, light industrial, and public uses. Cal Water operates and maintains the City’s Municipal Water System under contract.

The City’s Wholesale Water System service area includes all lands within the City’s boundaries. The City’s Kern River water rights provide water supplies to the Wholesale Water System. These supplies are transported though the Kern River channel and canal systems for delivery to water treatment plants owned and operated by Cal Water and KCWA’s ID4 and to surface water recharge areas such as the City’s 2800 Acre recharge facility. The City’s surface water recharge operations with Kern River water are for the benefit of the retail water suppliers providing service to City area through their respective groundwater wells. The location of City wells, water treatment plants, and water facilities used for recharge of Kern River supplies within the Wholesale Water System service area are shown on Plate 4.

3.02 Service Area Climate
______________________________________________________________________________________ California Water Code
Describe the climate of the supplier (10631(a)).
______________________________________________________________________________________ The City is located in the southern San Joaquin Valley with elevations ranging from about 300 feet to about 800 feet. Precipitation mainly occurs during the months of October through April. Winter months are generally mild, with frequent fog occurring during December and January at times when cooler air is trapped in the valley by a high pressure system. Summer months are typically hot and dry. Table 3-0 presents the monthly average rates of evapo-transpiration (Eto), minimum and maximum temperatures, and precipitation within the service area.

3.03 Service Area Population and Demographics
______________________________________________________________________________________ California Water Code
Describe the service area of the supplier, including current and projected population . . .

The projected population estimates shall be based upon data from the state, regional, or local service agency population projections within the service area of the urban water supplier and shall be in five-year increments to 20 years or as far as data is available (10631(a)).

Describe the service area of the supplier, including . . . other social, economic and demographic factors affecting the supplier's water management planning (10631(a)). ______________________________________________________________________________________ Since data from the DWR’s Population Tool for census year 2020 was not available at the time of preparation of this UWMP, the 2025 population for the Municipal Water System Service Area was determined using an estimated population per household for the 2020-2024 period from the US Census website1 and the estimated number of households associated with the residential connections in the service area from Cal Water (developed as part of their 2025 eAR to the SWRCB-DDW).

The estimated 2025 population is therefore calculated as 3.14 persons per household multiplied by 54,493 households or about 171,100 persons. Population projections for the years 2030 through 2045 were calculated based on a population growth rate for the Metro Bakersfield Area of 1.4 percent per year per the 2022 Regional Transportation Plan (RTP) prepared by the Kern Council of Governments (Kern COG) 2. This is consistent with the growth rate in the City’s residential water service connections over the past 5 years.

See Table 3-1 Retail.

The population per household in the City has increased from about 2.77 persons per household in 2000 to 1 https://www.census.gov/quickfacts/fact/table/bakersfieldcitycalifornia/PST045224 accessed 6/18/2026. 2 2020-2046 Forecast Growth Average Annual Rate for Metro Bakersfield Population per Table 3-2: Growth Trends for Kern County and Selected Communities

3.14 persons per household in 2020-2024 based on US Census estimates. Construction of Accessory Dwelling Units (ADUs) will likely continue this trend. ADUs represented about 9% of total single family residential building permits based on 2024-2025 building permit records from the City.

The State of California Department of Finance (DOF) prepares reports with population estimates for Cities and Counties on an annual basis. The DOF report was used for the 2025 population estimate for the wholesale service area, which is assumed to be the same as the City of Bakersfield City boundary.

Population projections for the years 2030 through 2045 were estimated using the same 1.4 percent annual growth rate as used for the Municipal Water System Service Area. See Table 3-1 Wholesale.

There are a few Census Block Groups within the Municipal Water Service Area that qualify as Low-Moderate Income per the City of Bakersfield Planning Division. These areas are estimated to comprise approximately 3 percent of the City’s retail service area. The City is in the process of updating its General Plan, and the current Housing Element was adopted in September 2025. Data provided in the Housing Needs Assessment3 indicates that approximately 48 percent of the overall City population is identified as low or very low income. The City continues to have a relatively high number of persons per household as reflected in its population estimates.

City of Bakersfield 4-3
2025 Urban Water Management Plan
The “Making Conservation a California Way of Life” regulation went into effect on January 1, 2025 which provides methodology whereby urban water use objectives (UWUOs) are calculated for each urban water supplier based on residential water use criteria (both indoor and outdoor), Commercial, Institutional, and Industrial (CII) performance measures including dedicated irrigation metering, and water system real losses.

The continued implementation of demand management measures to meet these UWUOs will result in decreasing per capita water use in the future. Estimates prepared by SWRCB staff indicate that the City’s water use would exceed its UWUO by approximately 39% in 2040 based on current indoor and outdoor water usage data. The breakdown of water deliveries to the various water use types in 2025 was found to be similar to that in 2020.

Future total residential water use is estimated based on the projected population data from Table 3-1 Retail and assumes compliance with UWUOs would result in a 2 percent annual reduction in future per capita residential water use from 2025 through 2040. Future water use for other than single family residential connections is projected to increase based on the 1.4% annual growth factor. Single-family residential water use is then calculated as the estimated total residential water use less the projected multi-family residential water use. Other water use and losses are estimated at 8% of total water use, which covers system losses as well as non-revenue water used for backwash, operational flushing, and fire department usage.

Table 4-2 Retail includes projections of the City’s Municipal Water Service Area water use for the years 2030 through 2045 in five-year increments.

4.04 Climate Change Considerations
______________________________________________________________________________________ California Water Code
It is the intention of the Legislature, in enacting this part, to permit levels of water management planning … while accounting for impacts of climate change (10630). ______________________________________________________________________________________ Climate Change impacts were modeled for the Kern County Subbasin Groundwater Sustainability Plan (KCSGSP). Considerations included increases in water demands using DWR climate change factors and guidance. DWR climate change guidance referenced in the KCSGSP indicates that a change in timing of Kern River flows is anticipated, with more flows in the winter and early spring and less in the summer.

However, the total Kern River flow volume is not expected to change significantly. Section 9.6 Projected Future Subbasin Water Budget from the KCSGSP is included as Appendix C.

The Kern River is the primary water source for the City of Bakersfield. The City’s water use projections are expected to adequately consider climate change impacts during the period covered by this UWMP.

______________________________________________________________________________________ The City pumps groundwater and recharged surface water from the Kern County Subbasin of the San Joaquin Valley Groundwater Basin (Groundwater Basin No. 5-22.14) which is currently non-adjudicated. The Kern County Subbasin is designated as critically overdrafted and identified as a high-priority basin in the latest version of Bulletin 118 published by the DWR. The City is a member of the Kern River Groundwater Sustainability Agency (KRGSA) which covers approximately 361 square miles overlying the Kern County Subbasin. Other member agencies include the Kern Delta Water District and KCWA’s ID4. The KRGSA was formed in compliance with the Sustainable Groundwater Management Act (SGMA) to cooperatively manage local groundwater in a sustainable manner.

In response to deficiencies identified in the GSPs initially submitted to DWR, primary regulatory oversight of the Kern County Subbasin was temporarily shifted to the State Water Board in March 2023. The KRGSA subsequently became a participant in the Kern County Subbasin Groundwater Sustainability Plan (KCSGSP), with the intent to coordinate groundwater management throughout the entire 2,800 square mile Subbasin. An Amended KCSGSP was adopted in August 2025 and submitted to the State Water Board and DWR for review. State Water Board staff completed review of the adopted KCSGSP and returned the Kern County Subbasin to the DWR’s jurisdiction in December 2025.

Kern River water supplies are recharged to the groundwater basin by the Wholesale Water System for the benefit of retail water suppliers throughout the City, including the City’s Municipal Water System. Historic groundwater and recharged surface water pumping volumes within the Municipal Water System service area for the years 2021 through 2025 are provided in Table 6-1 Retail. The Wholesale Water System does not pump groundwater. Therefore, Table 6-1 Wholesale does not apply and is not included in this UWMP.

NOTES:

The Municipal Water System has sufficient redundancy to allow for wells and other facilities to be taken offline as needed for maintenance or repairs. The City has installed standby generators at its well facilities so that it can continue to provide water supply in the event of an electrical power outage. Wellhead groundwater treatment facilities have been installed where necessary in order to continue providing water supplies that meet current potable water standards.

City of Bakersfield 6-3
2025 Urban Water Management Plan

6.03 Surface Water
The Municipal Water System receives treated surface water supplies from Cal Water’s North Garden (Northwest) Treatment Plant and Kern County Water Agency ID4’s Henry C. Garnett Water Purification Plant. The Wholesale Water System provides Kern River supplies to the Cal Water Northwest and Northeast Treatment Plant. The Henry C. Garnett Water Purification Plant treats SWP supplies. When SWP supplies are not available from KCWA’s ID4, the City is able to deliver its Kern River supplies to KCWA’s ID4 for treatment in place of SWP supplies.

The Wholesale Water System provides groundwater recharge of Kern River water supplies both by transportation through the Kern River and unlined portions of City canals, including the Carrier Canal, and within groundwater replenishment areas such as the City’s 2800 Acres recharge facility, Truxtun Lakes, Aera Park, and the Park at Riverwalk. The Environmental Impact Report (EIR) for the Kern River Flow and Municipal Water Program estimated the City’s Kern River water supplies for both urban use and agricultural use to average about 135,000 acre-feet per year (see Appendix D). Approximately 100,000 acre-feet of the 135,000 acre-feet is designated for urban use The City has storage rights in Lake Isabella that allows for flexibility in the management of its Kern River supplies.

6.04 Stormwater
The City maintains almost 400 stormwater basins that capture precipitation and recharge the groundwater basin. As noted in the City’s 2020 UWMP, these stormwater basins are estimated to capture and recharge approximately 16,000 acre-feet per year of stormwater runoff on average, and approximately 4,272 acre-feet per year of additional stormwater runoff is estimated to be captured and diverted into the Kern River and unlined canals on an average annual basis. This captured stormwater becomes part of the City’s groundwater and recharged water supplies as described in Section 6.02.

6.05 Wastewater and Recycled Water
______________________________________________________________________________________ California Water Code
The plan shall provide, to the extent available, information on recycled water and its potential for use as a water source in the service area of the urban water supplier. The preparation of the plan shall be coordinated with local water, wastewater, groundwater, and planning agencies that operate within the supplier’s service area, and shall include the following:
a) A description of the wastewater collection and treatment systems in the supplier’s service area, including a quantification of the amount of wastewater collected and treated and the methods of wastewater disposal.
b) A description of the quantity of treated wastewater that meets recycled water standards, is being discharged, and is otherwise available for use in a recycled water project. c) A description of the recycled water currently being used in the supplier’s service area, including, but not limited to, the type, place, and quantity of use. d) A description and quantification of the potential uses of recycled water, including, but not limited to, agricultural irrigation, landscape irrigation, wildlife habitat enhancement, wetlands, industrial reuse, groundwater recharge, indirect potable reuse, and other appropriate uses, and a determination with regard to the technical and economic feasibility of serving those uses.

6.11 Summary of Existing and Planned Sources of Water
______________________________________________________________________________________ California Water Code
Identify and quantify, to the extent practicable, the existing and planned sources of water available to the supplier over the same five-year increments described in subdivision (a), providing supporting and related information, including all of the following… (2) When multiple sources of water supply are identified, a description of the management of each supply in correlation with the other identified supplies. (10631 (b)) A detailed description and analysis of the amount, and location of groundwater that is projected to be pumped by the urban water supplier. The description and analysis shall be based on information that is reasonably available, including, but not limited to, historic use records (10631(b)(4)(E)).
______________________________________________________________________________________ The Municipal Water System service area relies significantly on pumped groundwater and recharged surface water supplies to meet its demands. The City’s groundwater and recharged surface water supplies are expected to be sustainable and available to meet the projected demands of its service area for the next 50 years and beyond, especially with the reduction in demands anticipated due to compliance with UWUOs.

The City’s proposed expansion of its recycled water use will provide additional water supplies for the benefit of the groundwater basin. Purchases of treated surface water supplies from Cal Water Northwest Treatment Plant (treated Kern River supplies) and Henry C. Garnett Water Purification Plant (treated SWP supplies from KCWA ID4) are anticipated to be available to meet demands as projected in this Plan. When SWP supplies are not available from KCWA’s ID4, the City can deliver Kern River supplies to KCWA’s ID4 for treatment in place of SWP supplies.

Actual supplies for 2025 for the Municipal Water System service area are summarized in Tables 6-8 Retail.

Projections for water supplies are provided in Table 6-9 Retail. Projections of groundwater and recharged water pumping are estimated as the difference between the projected demands from Table 4-2 Retail and estimated purchases of treated surface water supplies.

6.12 Energy Use
______________________________________________________________________________________ California Water Code
In addition to the requirements of Section 10631, an urban water management plan shall include any of the following information that the urban water supplier can readily obtain:
(1) An estimate of the amount of energy used to extract or divert water supplies. (2) An estimate of the amount of energy used to convey water supplies to the water treatment plants or distribution systems.
(3) An estimate of the amount of energy used to treat water supplies. (4) An estimate of the amount of energy used to distribute water supplies through its distribution systems.
(5) An estimate of the amount of energy used for treated water supplies in comparison to the amount used for nontreated water supplies.
(6) An estimate of the amount of energy used to place water into or withdraw from storage. (7) Any other energy-related information the urban water supplier deems appropriate (10631.2(a)).
______________________________________________________________________________________ The estimated energy used to extract, divert, convey, treat, and distribute water for the City’s Municipal Water System was determined from the energy utility invoices received during 2025 for its various water system facilities. The City does not use significant amounts of self-generated energy in its Municipal Water System. Energy is used primarily for groundwater wells and booster pumps. Data is not readily available to provide separate estimates of the amount of energy used for each component of the City’s Municipal Water System operations or to determine the amount used for treated water supplies in comparison to the amount used for nontreated water supplies.

The Municipal Water System’s estimated energy intensity for 2025 is calculated based on the Total Utility Approach as described in Appendix O of the Guidebook and shown in Table O-1B. The estimated energy use of 19,244,230 kilowatt-hours (kWh) for 2025 does not include recycled and wastewater related energy use. Therefore, the volume of water entering the process is the total municipal water use of 46,149 AF from Table 4-1 Retail.

Section 7: Water Service Reliability and Drought
Risk Assessment

7.01 Water Service Reliability Assessment
______________________________________________________________________________________ California Water Code
Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the long-term total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier (10635(a)).

A detailed discussion of anticipated supply availability under a normal water year, single dry year, and droughts lasting at least five years, as well as more frequent and severe periods of drought, as described in the drought risk assessment. For each source of water supply, consider any information pertinent to the reliability analysis conducted pursuant to Section 10635, including changes in supply due to climate change (10631(b)(1)).
______________________________________________________________________________________ The City anticipates that its sources of supplies will be available to meet demands on a consistent basis for all year types throughout the planning horizon of this UWMP. The City’s Wholesale Water System replenishes its Kern River supplies to the groundwater basin for the benefit of retail water suppliers providing service to City areas through their respective groundwater wells. The KCSGSP includes management actions and proposes projects to maintain the groundwater resource in a sustainable condition under future climate change conditions through the year 2070. The City and other retail water suppliers within the Wholesale Water System service area are able to increase use of their groundwater wells during years of reduced Kern River supplies.

The Municipal Water System service area relies significantly on pumping of groundwater and recharged surface water supplies to meet its demands. With implementation of the projects and management actions identified in the KCSGSP, the City’s groundwater and recharged surface water supplies are anticipated to be sustainable and available to meet the projected demands of its Municipal Water System service area.

The City will construct new wells or rehabilitate existing wells as required to meet projected water demands.

Groundwater wells will be equipped with wellhead treatment as necessary to remove contaminants such as arsenic, 1,2,3-Trichloropropane, and Perfluorooctane Sulfonate (PFOS) that exceed water quality standards.

When SWP supplies are not available from KCWA ID4, the City is able to deliver its Kern River supplies to KCWA’s ID4 for treatment in place of SWP supplies.

The anticipated reliability of the City’s water supplies to meet the needs of the Municipal Water System service area for the various water year types is summarized in Table 7-1 Retail. The historic dry period of 2012 through 2016 is shown as the basis of water year data for the multiple dry year scenarios with 2015 shown as the basis of water year data for the single dry year.

2025 Urban Water Management Plan

7.02 Description of Management Tools and Options
______________________________________________________________________________________ California Water Code
An urban water supplier shall describe in the plan water management tools and options used by that entity that will maximize resources and minimize the need to import water from other regions (10620(f)).
______________________________________________________________________________________ The tools and options used by the City to maximize resources and minimize the need to import water from other regions include the following, which are described more fully in other sections of the Plan.  Kern River Optimized Conjunctive Use -The City plans to use its full entitlement, less current obligations, to mitigate undesirable results for water levels and water quality in the Urban MA.

Expected benefit is 67,930 acre-feet per year.
 Expand Recycled Water Use in the KRGSA - The City will increase recycled water use inside of the KRGSA from its WWTP No. 3 in 2026 when a contract for use outside of the KRGSA expires (about 72% is currently used outside of the KRGSA). Expected benefit is 13,407 acre-feet per year.  Additional Urban Conservation Measures - To reduce urban demand, additional conservation measures could be considered by the City and other urban retail water purveyors. Such actions are documented in the UWMPs and strict adherence to permanent reductions in urban demand by 2020 are underway. A decrease in the long-term per capita water use is provided in UWMPs and embedded in the projected water budgets for the KRGSA.

7.03 Drought Risk Assessment
______________________________________________________________________________________ California Water Code
Every urban water supplier shall include, as part of its urban water management plan, a drought risk assessment for its water service to its customers as part of information considered in developing the demand management measures and water supply projects and programs to be included in the urban water management plan. The urban water supplier may conduct an interim update or updates to this drought risk assessment within the five-year cycle of its urban water management plan update. The drought risk assessment shall include each of the following:
(1) A description of the data, methodology, and basis for one or more supply shortage conditions that are necessary to conduct a drought risk assessment for a drought period that lasts five consecutive water years, starting from the year following when the assessment is conducted.
(2) A determination of the reliability of each source of supply under a variety of water shortage conditions. This may include a determination that a particular source of water supply is fully reliable under most, if not all, conditions. (3) A comparison of the total water supply sources available to the water supplier with the total projected water use for the drought period (4) Considerations of the historical drought hydrology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria (10635(b)). ______________________________________________________________________________________ City of Bakersfield 7-7
2025 Urban Water Management Plan
The water supplies for the Municipal Water System are projected to be adequate to meet demands during the years of the Drought Risk Assessment. The City’s Kern River supplies have been replenished to the groundwater basin and provide reliability of groundwater supplies for a five-year drought. When SWP supplies are not available from KCWA’s ID4, the City is able to deliver its Kern River water to KCWA’s ID4 for treatment in place of SWP supplies. The Five-Year Drought Risk Assessment for the Municipal Water System is presented in Table 7-5 Retail.

Although the City anticipates no reduction in its available supplies, it is assumed that water supplies and water use are reduced by 10 percent in the third through fifth dry years as a result of water conservation measures expected to be implemented during an extended drought period. Since groundwater pumping is limited to the amount needed to meet use, the water use is shown to be equal to supplies for 2026 and 2027.

In years 2028 through 2030, the reduction in use will be accomplished by implementation of appropriate measures from the Water Shortage Contingency Plan (See Section 8). Recycled water supplies and the corresponding landscape irrigation use are not included in Table 7-5 Retail as these do not impact dry year water supply planning for the Municipal Water System.

The Five-Year Drought Risk Assessment for the Wholesale Water System is presented in Table 7-5 Wholesale. Water supplies are based on the five-year drought period from Table 7-1 Wholesale. The Wholesale Water System use of 100,000 AF annually includes water supplies used for groundwater recharge. Total water use in Table 7-5 Wholesale is shown to be equal to total supplies in each year since the Wholesale Water System replenishes its Kern River supplies to the groundwater basin for the benefit of retail water suppliers providing service to City areas through their respective groundwater wells.

Water supplies are stored within the groundwater basin in wet years and extracted by the various retail water agencies to meet their water use when surface water supplies are reduced. Wholesale Water System groundwater recharge in future drought years will be reduced to match available supplies. Water use within the retail water agencies is also anticipated to be reduced due to implementation of measures from their respective Water Shortage Contingency Plans (see Section 8 for information on the City’s WSCP).

9.01.5 Programs to Assess and Manage Distribution System Real Loss (Municipal Water System)
The City’s Municipal Water System conducts the required annual water audits for the Municipal Water System using the AWWA Water Audit software. Water production and consumption are monitored to identify possible areas of leakage. Customer billing records are monitored for unusually high water use. A leak detection and repair program is implemented through Cal Water, which provides maintenance of the Municipal Water System under contract and makes repairs as needed.

The City partners with Cal Water to provide water efficiency inspections and landscape water surveys as requested by customers to identify problems and recommend repairs or improvements. Large City owned landscaped areas include master control systems that monitor the irrigation system and alert staff to potential water line leaks or sprinkler head breaks.

9.01.6 Water Conservation Program Coordination and Staffing Support The City partners with Cal Water for the implementation of its Water Conservation Program. Cal Water maintains a Water Conservation Program Coordinator that oversees the water conservation programs available to the City’s Municipal Water System service area customers. The Wholesale Water System does not have a water conservation program coordinator.

Kern County Subbasin
Groundwater Sustainability Plan 9-64

9.6 Projected Future Subbasin Water Budget

Projected (future) water budgets for the Kern Subbasin were developed using the C2VSimFG-Kern. These projected water budgets establish expected Baseline conditions to evaluate the impacts of GSP implementation. Three projected scenarios, each representing a different expected future hydrologic condition, were developed for the Kern Subbasin by adapting C2VSimFG-Kern as follows:
• Future Baseline Conditions: Repeat historical hydrology with expected future water supply.

Projected future water budgets were developed for the three scenarios listed above over a 50-year planning and implementation horizon. To assess the sustainability of the proposed Plan, the C2VSimFG-Kern model future scenario input files were then modified to create three additional scenarios that incorporate all the P/MAs. The six total scenario models provide a basis of comparison for evaluating proposed P/MAs over the SGMA planning and implementation horizon with varying degrees of climate change impacts.

9.6.1 Projected Water Budget Methods and Data Sources

C2VSimFG-Kern was modified to incorporate projected future hydrology and land use using analog data from the historical C2VSimFG-Kern model. This approach meets GSP requirements using:
• A 50-year time-series of historical precipitation, evapotranspiration, and stream flow information as the future Baseline hydrology conditions. • The most recent land use, satellite-based evapotranspiration, crop coefficient and urban population growth information as the Baseline condition for estimating future water demands.
• The most recent water supply projections as the Baseline condition for estimating future surface water supply.
• DWR (2018a) Climate Change Guidance and Data Sets to incorporate estimated climate change conditions for the Kern Subbasin. • Specialized analysis of the Kern River watershed and estimated runoff volumes under climate change conditions.
• Specialized analysis of CVP deliveries to Kern County under climate change conditions incorporating implementation of the San Joaquin River Restoration Program.
• Specialized analysis of SWP deliveries to Kern County under climate change conditions incorporating implementation of the Operations, Criteria, and Plan (OCAP) Biological Opinion and recent changes in Table A and Article 21 allocations.

9.6.2 Development of Projected Water Budget Scenarios

Projected water budgets for the Kern Subbasin were developed using the C2VSimFG-Kern to evaluate the performance of P/MAs with respect to achieving  23 CCR § 354.18(c)(3)

groundwater sustainability. Participating agencies provided a list of projected future P/MAs to be implemented between WY2021 and WY2040. Projected future conditions under Baseline conditions, 2030 Climate Conditions, and 2070 Climate Conditions were simulated both with and without these projects through WY2070 using the C2VSimFG- Kern model, for a total of six projected scenarios.

Proposed future P/MAs were provided by GSAs. The types of P/MAs are summarized as follows:
• “Demand Reduction” P/MAs involve reducing the volume of water use, typically through changes in land use, including:
o Agricultural demand reduction projects through incentives or actions to reduce crop water use.
o Agricultural land retirement and conversion of agricultural land to recharge basins.
o Conversion of agricultural land to urban land.
• “Supplemental Water Supply” P/MAs involve increasing water supplies, including:
o Increased surface water imports generally resulting from projected, or already contracted, water purchases.
o New water conveyance facilities including pipelines and reservoirs to increase flexibility.
o Expansion of surface water delivery areas to reduce groundwater usage. • “Other Local Water Supply” P/MAs involve increasing local water supplies, including:
o Utilizing treated wastewater derived from both urban areas and oil production operations; increased utilization occurs in both existing and new locations. o Increased stream flow diversions: these include exercising riparian water rights and diverting flood flows.
o Reallocation of water; generally reducing sales of surface water and stored surface water in some GSAs and using this water within the agency. o Augmenting surface water supplies with treated brackish water.

Some P/MAs are implemented gradually over many years, with savings increasing each year over the implementation period. Some are implemented only in certain years (wet years, for example). The anticipated average-annual water supply benefit of the proposed P/MAs steadily increases over the 20-year period from WY2021 to WY2040 to represent the implementation of the Kern Subbasin Plan. This increasing trend, as shown as the average-annual water supply benefit over five-year increments shown in Figure 9-17, is summarized as follows:

Kern County Subbasin
Groundwater Sustainability Plan 9-67
• About 116,000 AFY over the first five-year period (WY2021 to WY2025). • About 216,000 AFY over the second five-year period (WY2026 to WY2030). • About 343,000 AFY over the third five-year period (WY2031 to WY2035). • About 361,000 AFY over the fourth five-year period (WY2036 to WY2040).

The anticipated water supply benefit of the proposed P/MAs included in the C2VSimFG-Kern projected future simulations is 422,000 AFY over the period from WY2041 to WY2070. Benefits of implementing these P/MAs over the 20-year implementation period are summarized in Figure 9-17.

9.6.2.1 Projected Future Baseline Development
Projected water budgets are required by SGMA Regulations to represent future conditions over a 50-year planning and implementation horizon. A Baseline condition was developed that projects water supply, demand and operations based on current land use and expected water supply availability over 50 years. The Baseline then serves as a basis of comparison for evaluating proposed P/MAs for achieving sustainability over the planning and implementation horizon. Each predictive scenario model simulates the 50-year planning and implementation period WY2021 to WY2070.

Development of the projected future Baseline conditions is summarized below.

9.6.2.2 Projected Future Time Period Development
WY1995 to WY2014 is used as a historical hydrology period because detailed demand and supply data are available for this period, and because most Kern Subbasin water delivery infrastructure was fully developed by the middle of this period. The average Kern River inflow for this period is also very close to the long-term average Kern River inflow.

The projected future simulation period is based on repeating the WY1995 to WY2014 historical study period. Since the historical period is only 20 years long, the 50-year sequence of hydrology was developed by repeating data from the historical period as shown in Appendix H-1, Table 18, and summarized below:
• Simulation period WY2021 to WY2032 uses the historical period WY2003 to WY2014.
• Simulation period WY2033 to WY2052 uses the historical period WY1995 to WY2014.
• Simulation period WY2053 to WY2070 uses the historical period WY1995 to WY2012.

This sequence is used to match long-term average flows on the Kern River, and to ensure that the 50-year simulation period does not end in an extreme drought or extreme wet year. By starting the projected 50-year future simulation period with

Kern County Subbasin
Groundwater Sustainability Plan 9-68
WY2003, the period has approximately 100 percent of the long-term average streamflow conditions on the Kern River, as indicated by an average annual Kern River Index of 100 percent. The sequence includes the appropriate range of hydrologic conditions including extremely wet years and extended periods of drought.

9.6.2.3 Development of Key Baseline Data Sets
Key required components for the Projected Future Baseline, as summarized in the DWR Water Budget Best Management Practices (DWR, 2016B) include the following:
• The projected Baseline hydrology conditions use 50-years of historical precipitation and streamflow following the sequence outlined in Section 6.1. • Surface water supplies are based on available information from DWR and others to project future water imports from the SWP, CVP, and Kern River diversions. For the Kern River, recent diversion practices based on entitlements are used to develop water use consistent with the Baseline hydrology. • WY2013 land use is used as current land use as representative of land use prior to implementation of SGMA in 2015. Drought conditions in WY2014 and WY2015 resulted in reduced agricultural production, and more recent land use begins to include changes as a result of SGMA.
• Consumptive use for agriculture and undeveloped lands is based on the current land use and ITRC METRIC-based evapotranspiration. Following DWR guidance, ITRC METRIC data over the Baseline period is varied according to varying hydrologic conditions (e.g., water year type).
• Urban water demand is based on projections from recent urban water management plans to meet regulations for future water use. Urban demand is estimated in the model based on projected urban population growth and per capita water demand information (including recent regulatory guidance). • Small watershed inflows use the same parameters as the historical C2VSimFG-Kern model; however, volumes varied based on changes in the precipitation and ET under the 2030 and 2070 climate change conditions.

Time-series input data were first developed for the Baseline scenario model for WY2021 to WY2070. Development of this time-series input data generally involved repeating time-series data from the historical C2VSimFG-Kern in the appropriate sequence. The following time-series data were developed for each scenario:
• Precipitation rates
• Evapotranspiration rates
• Surface water inflow rates
• Surface water diversion and delivery rates
• Specified groundwater pumping rates
Baseline scenario model time-series data files were then modified following DWR guidelines to produce time-series input data for the 2030 Climate Conditions and 2070 Climate Conditions scenarios. C2VSimFG-Kern input data were modified only in Kern

Kern County Subbasin
Groundwater Sustainability Plan 9-71
County. C2VSimFG-Kern input data for areas outside of Kern County were not modified.

These baseline data sets are incorporated into the model files to develop the projected future water demand and supply under Baseline, 2030 Climate and 2070 Climate conditions. A summary of the development of the projected future water demand and supply is discussed below.

9.6.2.4 Projected Future Water Demand
The projected future water demand uses fixed WY2013 land use areas with historical evapotranspiration rates for the Baseline and modified evapotranspiration rates for the 2030 and 2070 Climate Scenarios. An increasing urban population was projected based on urban water management plans and other information to develop projected-future water demand for the Baseline, 2030 and 2070 Climate Scenarios.

9.6.2.5 Agricultural Water Demand
Evapotranspiration rates for the Baseline scenario model use repeating input evapotranspiration rates from C2VSimFG-Kern in the appropriate sequence. DWR provided monthly change factors for ETo values under 2030 and 2070 central tendency climatic conditions on a 6 km x 6 km Variable Infiltration Capacity Model (VIC) grid for calendar years 1915 through 2011 (DWR 2018A). The VIC grid IDs for each C2VSim subregion in the Kern Subbasin were identified and area weighted monthly ETo change factors were calculated for each subregion. Baseline scenario ETc rates for each subregion were then multiplied by the appropriate area-weighted ETo change factors to produce time-series ETc rates for the 2030 Climate and 2070 Climate scenarios.

Factors for calendar years 1959 to 1961 are used as analogs for calendar years 2012 to 2014.

9.6.2.6 Urban Water Demand
Urban water demand calculations include an indoor component and an outdoor component. Indoor urban water demands are based on the urban population and monthly per capita water demand. Future urban populations for Kern County urban areas are estimated using California Department of Finance population projections.

Future per capita urban water demands are estimated using projections from urban water management plans and California urban water conservation regulations, including SB 606 and AB 1668. Future outdoor urban water demands are based on ETc rates, which were modified as described in the Agricultural Water Demand section above.

9.6.2.7 Water Banking Recovery
Future water banking recovery rates use repeating historical recovery rates in the appropriate sequence. No adjustments were made to Baseline rates or to rates for 2030 and 2070 climatic conditions.

Kern County Subbasin
Groundwater Sustainability Plan 9-72

9.6.2.8 Projected Future Water Supply
Projected future precipitation, stream inflow and surface water imports time series were developed following DWR guidelines.

9.6.2.9 Precipitation Rates
Precipitation rates for the Baseline scenario model use repeating input precipitation rates from C2VSimFG-Kern in the appropriate sequence. DWR provided monthly change factors for precipitation under 2030 and 2070 central tendency climatic conditions on a 6 km x 6 km VIC grid for calendar years 1915 through 2011 (DWR 2018A). The VIC grid ID for each C2VSim element in the Kern Subbasin was identified and the Baseline scenario precipitation rates were multiplied by the appropriate factors to produce time-series precipitation rates for the 2030 Climate and 2070 Climate scenarios. Factors for calendar years 1959 to 1961 are used as analogs for calendar years 2012 to 2014.

9.6.2.10 Surface Water Inflow Rates
Surface water inflow rates for Poso Creek and the White River for the Baseline scenario model use repeating input inflow rates from C2VSimFG-Kern in the appropriate sequence. DWR (2018a) provided unimpaired streamflow change factor datasets for Central Valley streams, and an Excel spreadsheet tool to modify basin unimpaired streamflow using these change factors. The unimpaired streamflow change factors and spreadsheet were used to modify Baseline inflows to produce 2030 Climate and 2070 Climate scenario time series inflows for Poso Creek and White River.

Surface water inflow rates for the Kern River at First Point for the Baseline scenario model use repeating historical inflow rates from C2VSimFG-Kern in the appropriate sequence. Flows on the Kern River are regulated, so the unimpaired streamflow method is not appropriate for estimating future flows under 2030 and 2070 climatic conditions.

Projected Kern River flows at First Point under 2030 and 2070 central tendency conditions were estimated by GEI (2018) using calendar years 1956 to 2010 hydrology.

The analysis considered the impacts of changed runoff in each sub-watershed contributing to the Kern River to develop revised streamflow estimates for Kern River at First Point. Projected scenario flows for the Kern River at First Point for calendar years 2011 to 2014 are estimated using flows for analog years with similar annual flows and monthly flow pattern. Analog years 1986, 1991, 1990 and 1961 are used for calendar years 2011 to 2014 in the projected scenarios. Figure 9-18 graphically summarizes the changes in Kern River water supplies relative to historical data. The lower graph shown in Figure 9-18 shows the average monthly shift in Kern River inflows after applying 2030 and 2070 climate change guidance to historical flows. In general, the annual Kern River flows remain similar; however, the peak flows shift in time. The monthly shifts show an increase in flow during December through February and a decrease in flow during May, June, and July.

Kern County Subbasin
Groundwater Sustainability Plan 9-73

9.6.2.11 Surface Water Deliveries
Surface water delivery rates for the Baseline scenario model were developed by first repeating input surface water delivery rates from the C2VSimFG-Kern in the appropriate sequence and then modifying selected data sets. Surface water deliveries from local imported sources such as recycled produced water are held constant at WY2015 rates for all projected scenarios.

The Kern Subbasin is served by both the CVP and the SWP. Recent changes in CVP and SWP operations and their impacts on future surface water supplies are reflected in surface water diversion rates for the three scenarios.

Future CVP deliveries will be affected by implementation of the San Joaquin River Restoration Program (SJRRP) that includes the 2008 U.S. Fish & Wildlife Service biological opinion (BO) on the Long-Term Operational Criteria and Plan (OCAP) for coordination of the CVP and SWP.

Future CVP delivery projections developed by the Friant Water Authority (FWA) were used in place of DWR’s CVP projections. FWA (2018) used CalSim-II to develop projected surface water deliveries with SJRRP implementation under hydrological conditions representing the Baseline, 2030 Climate, and 2070 Climate conditions by delivery class for WY1922 to WY2003, and estimated allocations to each CVP contractor. The 2015.c data set is used for Baseline scenario CVP deliveries, the 2030.c data set is used for the 2030 Climate scenario CVP deliveries, and the 2070.c data set is used for the 2070 Climate scenario CVP deliveries. A summary of each of these data sets from FWA (2018) is provided below:
• “2015.c” was designed to represent current conditions, where implementation of the San Joaquin River Restoration Settlement (SJRRS) is limited by downstream capacity limitations and the climate and hydrology are assumed to be most similar to historical hydrologic conditions.
• “2030.c” was designed to represent near future climate conditions centered around 2030 and uses DWR’s central tendency climate projection. This scenario assumes implementation of the SJRRS.
• “2070.c” was designed to represent far-future climate conditions centered around 2070 and uses DWR’s central tendency climate projection. This scenario assumes implementation of the SJRRS.

CVP deliveries for WY2004 to WY2014 are estimated using deliveries for analog years WY1951 to WY1961; these analog years have a similar distribution of water availability.

Figure 9-19 graphically presents the average annual CVP deliveries to the Kern Subbasin based on the FWA (2018) guidance. The monthly values show a general decrease in deliveries but not a temporal shift. The net result of the climate change modifications is that CVP deliveries to the Kern Subbasin for the 2030 Climate scenario

Kern County Subbasin
Groundwater Sustainability Plan 9-74
are 80 percent of the Baseline scenario and CVP deliveries for the 2070 scenario are 68 percent of the Baseline scenario.

Future SWP deliveries will be affected by operational changes implemented between 2004 and 2008 including the OCAP BO, reduced Table A contract amounts and reduced Article 21 deliveries. DWR provided projected future deliveries from the CVP and SWP for WY1922 to WY2003, derived from CalSim-II modeling conducted for the Water Supply Investment Program (WSIP) (California Water Commission, 2016).

The SWP projections provided by DWR for WY1995 to WY2003 and historical deliveries for WY2004 to WY2014 were modified to incorporate the impacts of SWP operational changes in the three projected scenarios. A summary of the modifications to historical SWP deliveries to develop an equivalent projected-future SWP delivery schedule are summarized below:
• Baseline Hydrologic Conditions:
o WY1995 to WY2003 conditions are based on 2030-Level CALSIM increased by 3.03 percent.
o WY2004 to WY2007 conditions are based on historical data adjusted for OCAP BO.
o WY2008 to WY2014 conditions are based on historical data with the assumption that OCAP BO adjustments are already factored into the data. • 2030 Climate Conditions:
o WY1995 to WY2003 conditions are based on the 2030-Level CALSIM Projection.
o WY2004 to WY2007 conditions are based on OCAP BO adjustment reduced by 3.03 percent.
o WY2008 to WY2014 conditions are based on historical data reduced by 3.03 percent.
• 2070 Climate Conditions:
o WY1995 to WY2003 conditions are based on the 2070-Level CALSIM Projection.
o WY2004 to WY2007 conditions are based on OCAP BO adjustment reduced by 8.09 percent.
o WY2008 to WY2014 conditions are based on historical data reduced by 8.09 percent.

Kern County Subbasin
Groundwater Sustainability Plan 9-75
Figure 9-20 graphically illustrates the total changes in SWP deliveries to the Kern Subbasin. The net result of the climate change modifications is that SWP deliveries to the Kern Subbasin for the Baseline scenario are 83 percent of historical; for the 2030 Climate scenario are 80 percent of historical; and for the 2070 scenario are 76 percent of historical.

Figure 9-21 shows the composite changes in total surface water supplies from the Kern River, CVP, and SWP. The net result of the climate change modifications is that Kern River, CVP, and SWP deliveries to the Kern Subbasin for the Baseline scenario are 93 percent of historical; for the 2030 Climate scenario are 88 percent of historical; and for the 2070 Climate scenario are 85 percent of historical.

9.6.3 Additional Surface Water Supply Adjustments

Within the Kern Subbasin, water users engage in complex real-time water trading and wheeling activities to maximize water utilization, minimize waste and energy consumption, and meet immediate water needs. It would be difficult to project future surface water deliveries in the Kern Subbasin without the use of a surface water allocation model that simulates these water trading and wheeling activities. Therefore, for this modeling effort, monthly future-scenario agricultural, urban and recharge deliveries from sources originating outside the Kern Subbasin have been estimated by adjusting historical deliveries by the ratio of (total scenario inflows)/(total historical inflows) for each month, where total inflows are the sum of CVP deliveries, SWP deliveries and Kern River at First Point. In addition, Kern River flows at First Point flows above historical flows under the 2030 Climate and 2070 Climate scenarios have been proportionally added to selected recharge deliveries. This method is deemed adequate for the Subbasin-level future scenario analyses.

Some future scenario data sets do not cover the entire historical water budget period from WY1995 through WY2014. In these cases, data from an analog historical period with similar water availability has been used to fill in the missing data. The analog years for each data type are summarized as:
• For CVP deliveries (CalSim-II data), WY1951 to WY1961 have been used as analogs for missing WY2004 to WY2014 data; these analog years have a similar distribution of water availability.
• Projected future Kern River at First Point flows for calendar years 1986, 1991, 1990, and 1961 have been used as analogs for missing calendar years 2011 through 2014; each of these analog years had a similar historical annual flow volume and monthly distribution.
• For climatic data adjustment factors, calendar years 1959 to 1961 have been used as analogs to missing calendar years 2012 to 2014.

9.6.4 Projected Water Budget Results

The C2VSimFG-Kern was run for three scenarios representing Baseline, 2030 Climate and 2070 Climate conditions, both with and without the proposed P/MAs for a total of six projected future scenarios.

C2VSimFG-Kern calculates water budget components each month of the simulation period for each future scenario. Projected future water budgets developed based on the C2VSimFG-Kern simulation results with the proposed P/MAs are then compared to  23 CCR § 354.18(c)(3)
 23 CCR § 354.18(d)(3)

 23 CCR § 354.18(d)(3)

Kern County Subbasin
Groundwater Sustainability Plan 9-81
results for the future scenarios without the P/MAs to assess how these changes enhance groundwater sustainability within the Kern Subbasin.

The average annual value of each water budget component summarizes the impacts over 50 years with current water demands. The water budget results for the six Projected scenarios are presented in Appendix H-1, Table 19 through 24, and include averages over three different periods, which include:
• WY2021 to WY2040 – Implementation Period representing the 20-year period required by the SGMA Regulations to implement P/MAs to achieve sustainability.
• WY2041 to WY2070 – Sustainability Period representing the 30-year hydrologic period following the Implementation Period to assess the long-term sustainability of the proposed P/MAs with variable climatic conditions including periods with above average rainfall and extended droughts. • WY2021 to WY2070 – Simulation Period representing the entire 50-year projected future hydrologic conditions.

Changes to surface water diversions under the proposed P/MAs include monthly increases or reductions to 37 model diversions and the addition of seven new diversions. Ten new groundwater pumping wells have been added to simulate a new groundwater pumping program. Agricultural land use has been converted to native vegetation in ten GSAs, and to urban land use in three GSAs. The P/MAs included in the C2VSimFG-Kern scenarios are described in Section 14.

Baseline simulation results indicate that the Kern Subbasin has an average annual overdraft over the Sustainability Period (WY2041 to WY2070) of 324,326 AFY. By implementing the proposed P/MAs, the Kern Subbasin is forecasted to achieve sustainability by 2040 with an estimated 42,144 AFY of annual surplus over the Sustainability Period. With adjustments to account for limitations in the simulation (discussed in Section 9.8.2), the adjusted change in storage increases to 85,578 AFY.

Hydrographs of the simulated groundwater levels showing the projected future change in groundwater levels relative to the MO and MT for each monitoring well are provided in Appendix H-3. A regional model such as C2VSimFG-Kern does not perfectly represent local groundwater levels; however, it does represent long-term changes in groundwater levels. Therefore, the hydrographs are presented showing the projected future change in groundwater levels for each monitoring well. This was done using the superposition method where the simulated groundwater elevation change is calculated relative to the simulated March 2015 groundwater levels from the model. This simulated change in groundwater levels is then applied to the measured March 2015 groundwater level at that monitoring location. The result was to superimpose the simulated change in groundwater levels from the projected future C2VSimFG-Kern scenarios relative to the measured March 2015 groundwater level. The superposition process provided a more

Kern County Subbasin
Groundwater Sustainability Plan 9-82
realistic projection of future groundwater elevations relative to the MO and MT to aid sustainability planning including the development of Projects and Management Actions (P/MAs).

Collectively, the C2VSimFG-Kern simulation results indicate that the currently proposed P/MAs, once fully implemented, provide a reasonable approach to achieve sustainable management of the Kern Subbasin and can be adaptively managed to meet future challenges, as necessary. A summary of each of the six projected future water budgets from C2VSimFG-Kern is provided below.

9.6.4.1 Baseline Condition Water Budgets
For the Baseline Scenario without SGMA Projects, the groundwater budget for WY2021 to WY2040 (Appendix H-1, Table 19) repeats the 20-year historical hydrologic period so it provides a direct comparison of the differences between the projected future Baseline without SGMA Projects and the historical condition. The primary difference between historical conditions and the projected future Baseline is a nearly 20 percent decrease in imported surface water deliveries primarily from the SWP due to the OCAP BO. Over this period, the average groundwater pumping is 1,581,000 AFY, which includes agricultural pumping, urban pumping, and exported water. This results in an additional loss of groundwater storage of about 50,000 AFY over the 50-year projected future Baseline period.

The Baseline Scenario with SGMA Projects simulates the P/MAs applied to the Baseline Scenario. No other changes were made except for the addition of the P/MAs to provide a direct comparison of the relative benefits of about 422,000 AFY of proposed P/MAs. The groundwater budget for the Baseline Scenario with SGMA Projects is provided in Appendix H-1, Table 20.

Comparing the groundwater budget for WY2041 to WY2070 (Appendix H-1, Table 20) with the same period from the Baseline Scenario (Appendix H-1, Table 19) provides an evaluation of groundwater conditions after the P/MAs have been fully implemented. As a result of implementing the P/MAs, total net aquifer inflows increase about 135,400 AFY. The total net aquifer outflows decrease about 231,100 AFY due mostly to decreased groundwater pumping with agricultural demand reduction management actions.

The change in groundwater storage for the Baseline Scenario with SGMA Projects improves by about 360,000 AFY compared to the Baseline Scenario without SGMA Projects. This change results in a net gain in groundwater in aquifer storage for WY2041 to WY2070 of about 42,100 AFY. A comparison of the annual change in groundwater storage over the 50-year hydrologic period is shown in Figure 9-22. The time series shows that change in groundwater storage has stabilized to slightly increasing over the period from WY2041 to WY2070.

Kern County Subbasin
Groundwater Sustainability Plan 9-83
A comparison of the average annual water budget components for the two different Baseline Scenarios is shown in Figure 9-23. Over WY2041 to WY2070, the average groundwater pumping of 1,354,000 AFY for the Baseline Scenario with SGMA Projects (which includes agricultural pumping, urban pumping, and exported water) is over 270,000 AFY less than in the Baseline Scenario.

9.6.4.2 2030 Climate Change Water Budgets
The 2030 Climate scenarios simulate how the Kern Subbasin responds assuming hydrologic conditions representing a potentially drier climate and are based on the DWR Climate Change Guidance and Resource Guide (DWR, 2018A and 2018B). The 2030 Climate scenarios were run both with and without SGMA projects. Results for these 2030 Climate scenarios are shown in Figure 9-24.

The groundwater budget for the 2030 Climate Scenario without SGMA Projects for WY2041 to WY2070 (Appendix H-1, Table 21) is compared the same period for the Baseline Scenario without SGMA Projects to assess the relative change due to the climate change assumptions. The results show a net increase in aquifer inflows of about 44,700 AFY, however, the aquifer net outflows increase by about 101,200 AFY. This is mostly attributed to the climate shift to earlier rainfall making more surface water available for water banking and conjunctive use projects during the winter but less available for irrigation in the summer, resulting in higher groundwater pumping. The net change in groundwater storage is an additional decline of about 56,600 AFY due to the climate change impacts.

The 2030 Climate Scenario with SGMA Projects simulates the proposed P/MAs (Section 14) applied to the 2030 climate change conditions. No other changes were made to this scenario. The groundwater budget for the 2030 Climate Scenario with SGMA Projects is provided in Appendix H-1, Table 22.

Comparing the groundwater budget for WY2041 to WY2070 (Appendix H-1, Table 21) between the two 2030 Climate Scenarios, the total net aquifer inflows increase about 118,700 AFY due to increased water banking and conjunctive use projects and deep percolation. The total net aquifer outflows decrease about 249,300 AFY due mostly to decreased groundwater pumping with agricultural demand reduction management actions.

The change in groundwater storage for the 2030 Climate Scenario with SGMA Projects improves by about 368,000 AFY. This change results in a net decline in groundwater in aquifer storage over WY2041 to WY2070 of about 12,900 AFY. A comparison of the annual change in groundwater storage over the 50-year hydrologic period is shown in Figure 9-27. The time series shows that change in groundwater storage has stabilized to slightly increasing over the period from WY2041 to WY2070, but at a level below the results for the Baseline Scenario with SGMA Projects.

A comparison of the average annual water budget components for the two 2030 Climate Scenarios is shown in Figure 9-24. Over this period, the average groundwater pumping of 1,444,000 AFY for the 2030 Climate Scenario with SGMA Projects, which includes agricultural pumping, urban pumping and exported water, is over 290,000 AFY less than in the 2030 Climate Scenario without SGMA Projects.

9.6.4.3 2070 Climate Change Water Budgets
The 2070 Scenarios simulate how the Kern Subbasin aquifer would respond assuming hydrologic conditions representing a potentially very dry climate and are based on the DWR Climate Change Guidance (DWR, 2018A and 2018B). The 2070 Climate Change Scenarios were run both with and without SGMA Projects.

The groundwater budget for the 2070 Climate Scenario without SGMA Projects over WY2041 to WY2070 (Appendix H-1, Table 23) is compared the same period for the Baseline Scenario without SGMA Projects to assess the relative change due to the climate change assumptions. The results show a net increase in aquifer inflows of about 66,100 AFY, however, the net aquifer outflows increase by about 231,600 AFY. This is mostly attributed to an even greater climate shift to earlier rainfall making more surface water available for water banking and conjunctive use projects during the winter but less available for irrigation in the summer resulting in higher groundwater pumping. The net change in groundwater storage is an additional decline of about 165,500 AFY due to the climate change assumptions.

The 2070 Climate Scenario with SGMA Projects simulates the proposed P/MAs (Section 14) applied to the 2070 climate change conditions. No other changes were made to this scenario. The groundwater budget for the 2070 Climate Scenario with SGMA Projects is provided in Appendix H-1, Table 24. Comparing the groundwater budget for WY2041 to WY2070 (Appendix H-1, Table 23) between the two 2070 Climate Scenarios, the total net aquifer inflows increase about 106,300 AFY due to increased water banking and conjunctive use projects and deep percolation. The total net aquifer outflows decrease about 265,300 AFY due mostly to decreased groundwater pumping due to agricultural demand reduction management actions.

The change in groundwater storage for 2070 Climate Scenario with SGMA Projects improves by about 371,600 AFY. This change results in a net decline of groundwater in aquifer storage over WY2041 to WY2070 of about 118,300 AFY. A comparison of the annual change in groundwater storage over the 50-year hydrologic period is shown in

Figure 9-26. The time series shows that change in groundwater storage has stabilized to slightly increasing over the period from WY2041 to WY2070, but at a level below the results for the Baseline and 2030 Scenarios with SGMA Projects.

A comparison of the average annual water budget components for the two different 2070 Climate Scenarios is shown in Figure 9-25. Over this period, the average groundwater pumping of 1,559,000 AFY for the 2070 Climate Scenario with SGMA Projects, which includes agricultural pumping, urban pumping and exported water, is over 307,000 AFY less than in the 2070 Climate Scenario without SGMA Projects.

9.6.5 Change in Groundwater Storage

Groundwater sustainability for the Kern Subbasin was assessed using annual changes in groundwater storage. As discussed above, the decline in groundwater storage of the three future scenarios without P/MAs is significantly mitigated by the implementation of the proposed P/MAs. An assessment of the projected future groundwater storage change for the six projected future scenarios is summarized in Appendix H-1, Table 25.

The results of these simulations are summarized in Table 9-12.

These adjustments resulted in an overall improvement in the change in groundwater storage for the projected future water budgets. For the scenarios that include the SGMA Projects, the change in groundwater storage improves by 43,400 AFY (Baseline), 59,700 AFY (2030 Climate), and 72,300 AFY (2070 Climate). As a result of these adjustments, the adjusted change in groundwater storage for the three scenarios with SGMA Projects varied as follows:
• The Baseline Scenario with SGMA Projects changes from an increase of 42,100 AFY to an increase of 85,600 AFY.
• The 2030 Climate Scenario with SGMA Projects changes from a decline of 12,900 AFY to an increase of 46,800 AFY.
• The 2070 Climate Scenario with SGMA Projects changes from a decline of 118,000 AFY to a decline of 46,000 AFY.

These adjustments indicate areas of future improvement for C2VSimFG-Kern. Future updates to the model will address how to better simulate these conditions directly to limit the use of post-simulation adjustments.

9.7 Subbasin Sustainability Assessment

As defined by SGMA, the sustainable yield of a basin is the amount of groundwater that can be withdrawn annually without causing undesirable results. Although the SGMA Regulations require that a single value of sustainable yield must be calculated basin- wide, it should be noted that the sustainable yield can be changed with implementation of recharge projects, variations in climate, or changes in stream flow conditions. For the projected future scenarios, both the climate and the managed water supply operations are significantly affected which would lead to a change in the sustainable yield for the Kern Subbasin.

9.7.1 Sustainability Assessment
For the sustainability assessment, the sustainable yield was recalculated using the method described above, and the results are presented in Appendix H-1, Table 26.

Without the P/MAs, the percentage by which the total groundwater pumping exceeds the sustainable yield provides context to compare the significance of the level of groundwater pumping for the Kern Subbasin. For the scenarios without P/MAs, the groundwater pumping exceeds the sustainable yield on the order of 25 percent to 34 percent Appendix H-1, Table 26. However, with the proposed P/MAs, the groundwater pumping is less than the sustainable yield of the Kern Subbasin for the Baseline and 2030 climate scenarios and is within three percent of the sustainable yield for the 2070 Climate Scenario Appendix H-1, Table 23. This assessment indicates that the proposed P/MAs for the Kern Subbasin are of sufficient magnitude that, if fully  23 CCR § 354.18(d)(3)

Water Shortage Contingency Plan

Final Draft 2025 Bakersfield WSCP Page 1 of 10
City of Bakersfield
Water Shortage Contingency Plan
Final Draft – August 2026

Introduction
This Water Shortage Contingency Plan (WSCP) for the City of Bakersfield (City) has been prepared in accordance with current Water Code requirements and outlines a program for responding to water supply limitations. The intent of the water conservation measures and progressive restrictions on water use identified in this WSCP is to provide guidance to the City in managing and mitigating anticipated water supply shortages. The structured steps are designed to allow the City to assess its available water supplies and implement appropriate measures in response to actual conditions so that water shortages can be managed efficiently, predictably, and with accountability.

This WSCP includes the following elements as required by the Water Code:

1. Water Supply Reliability Analysis

2. Annual Water Supply and Demand Assessment Procedures

3. Six Standard Water Shortage Levels

4. Shortage Response Actions

5. Communication Protocols

6. Compliance and Enforcement (Municipal Water System service area only)

7. Legal Authorities

8. Financial Consequences of WSCP

9. Monitoring and Reporting (Municipal Water System service area only)

10. WSCP Refinement Procedures (Municipal Water System service area only)

11. Special Water Feature Distinction (Municipal Water System service area only)

12. Plan Adoption, Submittal and Availability

All of the above elements apply to the Municipal Water System service area. The elements shown as “Municipal Water System service area only” are not applicable to the Wholesale Water System service area.

The six standard water shortage levels and response actions defined in this WSCP increase restrictions on water use in response to the increasing levels of water shortage conditions. Other than response actions specified as applicable to the Wholesale Water System service area, t he implementation of response actions within this WSCP apply directly to the Municipal Water System service area. The retail agencies within the City’s Wholesale Water System service area are responsible for the implementation and enforcement of restrictions and prohibitions at the retail level within their respective service areas.

Each of the required elements is addressed in the following sections.

Final Draft 2025 Bakersfield WSCP Page 2 of 10

1. Water Supply Reliability Analysis
The City’s 2025 Urban Water Management Plan (2025 UWMP) update includes a water supply reliability analysis and drought risk assessment which are summarized herein. The City’s Wholesale Water System replenishes its Kern River supplies to the groundwater basin for the benefit of retail water suppliers providing service to City areas through their respective groundwater wells. The Kern River Groundwater Sustainability Agency (KRGSA) Groundwater Sustainability Plan (GSP) includes implementation of projects and management actions including the City’s conjunctive use optimization project and proposed expansion of its recycled water use which are anticipated to provide additional water supplies for the benefit of the groundwater basin. The Municipal Water System and other retail water suppliers within the Wholesale Water System service area are able to increase use of their groundwater wells during years of reduced Kern River supplies.

The Municipal Water System service area relies significantly on groundwater pumping to meet its demands. With implementation of the projects and management actions identified in the KRGSA GSP, the City’s groundwater supplies are anticipated to be sustainable and available to meet the projected demands of its Municipal Water System service area. The KRGSA GSP identifies sustainable management criteria for water levels based on the historic low water levels experienced in 2015- 2016.

Maintaining water levels above the Minimum Threshold levels identified in the KRGSA GSP is anticipated to allow the City’s wells to meet the demands of the Municipal Water System while minimizing undesirable results such as declining pump capacity, well inefficiency, water levels falling below pump intakes and pump screens, and degraded water quality.

As population and water demands increase with the Municipal Water System service area, the City will construct new wells required to meet the increased demands. Groundwater wells will be equipped with wellhead treatment as necessary to remove contaminants such as arsenic, 1,2,3-Trichloropropane (TCP), and Perfluorooctane Sulfonate (PFOS) that exceed water quality standards. When State Water Project (SWP) supplies are not available from Kern County Water Agency (KCWA) Improvement District No. 4 (ID4), the City is able to deliver its Kern River water to KCWA ID4 for treatment in place of SWP supplies.

The Drought Risk Assessment in the 2025 UWMP update evaluates the reliability of the Municipal Water System’s water supplies to meet drought conditions for 2025 and a subsequent five year period. The Drought Risk Assessment indicates that although the Municipal Water System’s water supplies are anticipated to be adequate to meet drought conditions during this period, it is assumed that water supplies and water use are reduced by 10 percent in the third through fifth dry years as a result of water conservation measures expected to be implemented during an extended drought period. T he reduction in demands will be accomplished by implementation of the appropriate Shortage Level and associated response actions in this WSCP.

A catastrophic event may result in a significant loss of City water supplies for a temporary period lasting from a day to a week or more. Examples of catastrophic events include earthquake, widespread power outage or other disaster. The WSCP shortage levels and response actions are intended to be implemented as appropriate to any future water shortage condition.

2. Annual Water Supply and Demand Assessment Procedures The Water Department Director will conduct an annual assessment of the City’s water supplies and demands and prepare an Annual Water Shortage Assessment Report (Annual Assessment Report) for both the Municipal Water System and Wholesale Water System considering the following:

Final Draft 2025 Bakersfield WSCP Page 3 of 10
• Current year unconstrained demand (considering weather, growth, and other influencing factors, such as policies to manage current supplies to meet demand objectives in future years, as applicable),
• Current year available supply (considering hydrological and regulatory conditions in the current year and one dry year),
• Existing infrastructure capabilities and plausible constraints, • A defined set of locally applicable evaluation criteria that are consistently relied upon for each annual water supply and demand assessment, and
• A description and quantification of each source of water supply.

The Annual Water Supply and Demand Assessment (AWSDA) will be completed and submitted to Department of Water Resources (DWR) prior to July 1 of each year per Water Code requirements.

If water shortage conditions requiring declaration of a Water Shortage Level 2 or higher are anticipated, the Annual Assessment Reports shall be submitted to the City Council for approval. The Annual Assessment Report for Water Shortage Level 2 or higher water shortage conditions will set for the criteria for determining when the particular Water Shortage Level is to be implemented and terminated as well as the appropriate shortage response actions, compliance and enforcement actions, and communications protocols consistent with the WSCP.

3. Six Standard Water Shortage Levels
As the water purveyor, the City must provide the minimum health and safety water needs of the Municipal Water System service area at all times. Implementation of this WSCP prioritizes water use as follows:

1. Health and safety – interior residential water use and fire suppression.

2. Commercial, Industrial, and Governmental – jobs and economic base.

3. Landscaping – residential, business/commercial, parks.

4. New Demand – all projects.

The six standard water shortage levels are defined by the State to allow for increasing levels of water conservation measures in response increasing severity of water shortage.

The applicable water shortage Level and response actions will depend on the causes, severity, and anticipated duration of the water supply shortage. The Six Standard Water Shortage Levels for both the Municipal Water System and the Wholesale Water System are summarized in Table 1.

4. Shortage Response Actions
The City has established the following shortage response actions within the Municipal Water System service area for the six standard water shortage levels defined above. The City will expand its public information campaign to encourage water conservation to achieve the appropriate decrease in demand for each shortage level. Water meter data will be monitored to determine the effectiveness of the shortage response actions in achieving the desired water demand reduction.

The Demand Reduction Actions to be implemented at each Shortage Level and the associated reduction in the shortage gap anticipated to be achieved due to implementation are summarized in Table 2 .

NOTES:

1. Target demand reduction for all measures for Shortage Level 1 is up to 10%.

2. Target demand reduction for all measures for Shortage Level 2 is up to 20%.

3. Target demand reduction for all measures for Shortage Level 3 is up to 30%.

4. Target demand reduction for all measures for Shortage Level 4 is up to 40%.

5. Target demand reduction for all measures for Shortage Level 5 is up to 50%.

6. Target demand reduction for all measures through Shortage Level 6 is greater than 50% up to the anticipated shortage gap.

The City Council shall have the authority to take any other action available to further reduce demands within the Municipal Water System service area to meet available supplies.

The Wholesale Water System will communicate with its retail water system customers regarding the anticipated shortage level and corresponding reductions in available water supplies. The Wholesale Water System will participate in public awareness campaigns and may implement measures to increase available supplies such as short-term water purchases or exchanges depending on the anticipated shortage gap.

Catastrophic Events:

Catastrophic events shall be evaluated as to their impact on the respective City Water System’s ability to deliver water supplies so that the appropriate water shortage level can be identified. The Water Department Director may immediately implement the appropriate shortage response actions due to a catastrophic event.

A seismic risk analysis was completed as a part of the Kern County Multi-Jurisdiction Hazard Mitigation Plan. Earthquake hazard was determined to be a high priority issue county wide. An earthquake can impact water delivery systems through damage to canal systems, water mains, and other water system facilities.

5. Communication Protocols
Table 3 provides the anticipated communication protocols for the various water shortage levels. The degree of communication increases with the water shortage level.

Final Draft 2025 Bakersfield WSCP Page 8 of 10
Table 3 – Communication Protocol by Shortage Level
Shortage Level Description
1 • Public information campaign to encourage water
conservation due to water shortage level.
• Communication with Wholesale Water System
customers regarding anticipated shortage conditions.
2 • Continue with Shortage Level 1 actions as appropriate for Shortage Level 2 conditions.
• Newsletter or bill insert to notify customers of declared water shortage level and implementation of mandatory
water use restrictions in the Municipal Water System
service area.
3 through 6
• Continue with Shortage Level 2 actions as appropriate for the declared Shortage Level condition.
• Press release notifying the public of declared water
shortage level and implementation of mandatory water
use restrictions and enforcement actions in the
Municipal Water System service area.

Emergency
Conditions
• Coordination with Kern County Emergency Operations
Center.
• Communication with Wholesale Water System
customers regarding anticipated shortage conditions.
• Notifications per Emergency Response Plan.
• Public information campaign to notify customers and
public of declared water shortage emergency and
implementation of mandatory water use restrictions in
the Municipal Water System service area.

6. Compliance and Enforcement (Municipal Water System Service Area) As required by Water Code Section 366, excessive water use by metered single-family residential customers and customers in multiunit housing complexes in which each unit is individually metered or submetered is prohibited during water shortage conditions of Level 3 or higher. Customers with excessive water use will be identified through meter data in comparison to the declared water shortage condition and reasonable water use based on factors such as the full-time occupancy of the household, amount of landscaped area, seasonal weather conditions, and the rate of evapotranspiration. The City will establish procedures to monitor compliance with the water use restrictions defined in this WSCP.

Enforcement of the WSCP shall be in accordance with Bakersfield Municipal Code Chapter 14.02 Water Use Regulations which addresses water use restrictions (14.02.010), penalties (14.02.020), administrative citations (14.02.030), administrative fines (14.02.035), administrative citation review process (14.02.040), and administrative hearing officer (14.02.045).

Final Draft 2025 Bakersfield WSCP Page 9 of 10

7. Legal Authorities
The City has the legal authority to declare water shortages through adoption of resolutions or ordinances.

The City shall declare a water shortage emergency in accordance with Chapter 3 (commencing with Section 350) of Division 1 general provision regarding water shortage emergencies in the California Water Code. The City shall coordinate with Kern County for the possible proclamation of a local emergency, as defined in Section 8558 of the Government Code.

Per Bakersfield Municipal Code Section 14.02.020, failure to comply with water use regulations may be punishable as an infraction, or misdemeanor pursuant to Bakersfield Municipal Code Section 1.40.010 , an administrative citation pursuant to Bakersfield Municipal Code Section 14.02.030, or any other available remedies allowed by law.

8. Financial Consequences of WSCP
The City reviews and revises its water rates for its Wholesale Water System and its Municipal Water System on a periodic basis. The projected costs of compliance with declared shortage levels will be considered as contingencies within future rate studies so that adequate reserves will be available to cover the additional expenses and shortfalls in revenue caused by periodic water shortages. The City may also defer planned maintenance or capital improvements until revenues recover. If expenses are found to exceed revenues, the City may implement other measures such as drought rate surcharges or increases in water rates to its customers.

9. Monitoring and Reporting (Municipal Water System Service Area) The City’s Municipal Water System is operated under a service contract with Cal Water. Under normal circumstances, water production is monitored daily. Total water production is reported monthly to the City’s Water Department and incorporated into the water supply report.

During a Level 1 through Level 2 water shortage, monthly production figures will be compared to the target monthly production to verify if the water use reduction goal is being met. If reduction goals are not being met, the Water Department Director will be notified so that corrective action can be taken.

During a Level 3 through Level 6 water shortage, the procedure listed above will be followed, with the addition of a weekly production report to the Water Department Director. During emergency shortages, production figures will be reported to the Water Department Director daily.

10. WSCP Refinement Procedures (Municipal Water System Service Area) The response actions and other considerations in this WSCP shall be reviewed on a periodic basis to determine the effectiveness of the implementation of the various measures to achieve the desired water demand reductions. Proposed revisions to the WSCP will be submitted to the City Council for adoption.

11. Special Water Feature Distinction (Municipal Water System Service Area) Special water features are defined as ponds, lakes, waterfall, fountains, or other water features that may be able to use recycled water or other non-potable supplies. The City may adopt measures that are specific to special water features that do not rely on potable water as a source of supply.

12. Plan Adoption, Submittal, and Availability
This WSCP was adopted by the City as a part of the adoption process for the 2025 UWMP at the Regular Meeting of the City Council on September 16, 2026. A public hearing was held on August 19, 2026. The

Final Draft 2025 Bakersfield WSCP Page 10 of 10
intent of the Public Hearing was to gather input from the public that is served by the City’s Municipal and Wholesale Water Systems as well as other interested entities. Written and verbal comments received during the public hearing process have been addressed as appropriate in the final WSCP document. A copy of the resolution adopting the WSCP is attached as Exhibit A.

The 2025 UWMP update and WSCP will be submitted to the California Department of Water Resources, the California State Library, and Kern County within 30 days of adoption by the City.

Commencing no later than 30 days after adoption, the City will have a copy of the 2025 UWMP update and WSCP available for public review at City Hall and posted on the City’s website.

For updates to the WSCP outside of the UMWP update cycle, the City shall make the revised WSCP available as follows:
• To its customers and Kern County no later than 30 days after adoption, • To Department of Water Resources in accordance with protocols for submission and using electronic reporting tools no later than 30 days after adoption, • For public review during normal business not later than 30 days after filing a copy of the WSCP with the Department of Water Resources.

Success Story , New Backup
Generators for Stormwater Pumps :

The City installed two new backup
generators for critical stormwater
facilities in 2018. The project was
funded through FEMA’s Hazard
Mitigation Grant Program.

Generators were installed at the
water pump stations at Beach Park
and the police pistol range. These
generators are a critical element for
flood protection needed to ensure the
reliability of two stormwater pump
stations that protect portio ns of the
Westchester and downtown areas.

Success Story , Talisman Sump: The
City is nearing completion of replacement of the Talisman Storm Pump Station (ma-FL-BK-112). COVID-19 substantially delayed this project due to availability of submersible and vertical turbine pumps used in high volume storm pump stations. The project is projected to be completed in winter of 2021.

Success Story, Seismic Retrofits: The City has undertaken a comprehensive seismic retrofit program for City-owned bridges. The City is currently completing construction of the final bridge that qualifies under the retrofit program at Manor Street.

1.4 Risk Assessment
The intent of this section is to profile the City of Bakersfield’s hazards and assess the City’s vulnerabilities, distinct from that of the County wide planning area. The hazard profiles in Vol ume 1 discuss overall impacts to the planning area and describes the hazard problem description, hazard extent, magnitude/severity, previous occurrences of hazard events and the likelihood of future occurrences. For more information on Risk Assessment Methodologies, see Vol. 1 and Appendix A.

1.4.1 Hazard Screening Criteria
Planning Team members from each participating jurisdiction collectively discussed which hazards should be profiled in the Plan and which should not. The results of that discussion can be found in Table 1-4.

Detailed hazard profiles of the most significant County wide hazards are described in Section 4 of Volume 1. The Planning Team reviewed previously-prepared hazard mitigation plans and other relevant documents to determine the realm of natural hazards that have the potential to affect the City of Bakersfield. Table 1-5 provides a crosswalk of hazards identified in Vol. 1 of this plan, the City of Bakersfield General Plan, and 2018 California State Hazard Mitigation Plan. The crosswalk was used to develop a preliminary hazards list, providing a framework for the Planning Team members to evaluate wh ich hazards were truly relevant to the City of Bakersfield and which ones were not. Section 1.4.2 below describes the hazard risk ranking process that was performed by the planning team which prioritized hazards that are specifically relevant to the City of Bakersfield.

Drought High priority county wide, profiled hazard
Dust Storms High priority county wide; profiled as part of Severe Weather Earthquake/ Geologic Hazards High priority county wide, profiled hazard Extreme Heat Profiled as part of Severe Weather hazard
Extreme Cold Extreme cold is rare in Kern County and not profiled in this plan Flood High priority county wide, profiled hazard
Hail Hail events are rare in Kern County and not profiled in this plan Fog While fog events do occur within Kern County, they are rare and are not considered a priority
Hazardous Material While hazardous materials can release and impact the County, there are better avenues to address this hazard outside this Plan.

High Winds/ Straight Line Winds High priority county wide, profiled as part of Severe Weather Insect Hazards While insects including Africanized honey bee and pine bark beetle exist in Kern County, this was not considered a priority and pests are not profiled in this plan
Levee Failure High priority county wide, profiled as part of Dam Failure Lightning Lightning was not identified as a priority for this plan.

Pandemic Disease While pandemic disease can impact the County, there are better avenues to address this hazard outside this plan.

Radon This hazard was not identified as a priority
Severe Thunderstorm Severe thunderstorms are rare in Kern County and not profiled in this plan.

Slope Failure High priority county wide, profiled hazard Soil Hazards High priority county wide, profiled hazard Terrorism/Human Caused Threats While terrorism is certainly a threat to the County and participating jurisdictions, it is best addressed in other plans as this HMP does not address human caused threats.

Tornado Impacts to the County from tornados are extremely unlikely, if any.

Volcanic Activity Due to distance from volcanoes and the limited chance of an eruption, this hazard was not identified as a priority.

Wildfire High priority county wide, profiled hazard
Winter Storm / Freeze Events Profiled as part of Severe Weather hazard

1.4.2 Hazard Risk Ranking
The City of Bakersfield’s Planning Team used the same hazard prioritization process as the Kern County Planning Committee. This process is described in detail in Section 4.3.1 of Vol . 1. Figure 1-3 displays the results of the hazard risk ranking exercise that was performed by the Planning Team. The Planning Team chose to assess the City of Bakersfield’s vulnerability to the following hazards:
▪ flood ▪ wildfire ▪ drought
▪ earthquake ▪ soil stability

All of these hazards have been profiled in Vol. 1 of this document. The purpose of this annex to address the City of Bakersfield’s vulnerability to these specifically-identified hazards.

1.4.3 Vulnerability Assessment
Assessing vulnerabilities exposes the unique characteristics of individual hazards and begins the process of narrowing down which areas within the City of Bakersfield are vulnerable to specific hazard events. The vulnerability assessment considered unique local knowledge of hazards and impacts and a GIS overlaying method for examining such vulnerabilities more in depth. Using these methods, participating jurisdictions estimated vulnerable populations, infrastructure, and potential losses from hazards.

1.4.3.1 Risk Assessment
Each participating jurisdiction developed a risk matrix that assessed the probability and impact of various hazards within the jurisdiction. Figure 1-3 is the jurisdiction’s risk assessment, which was completed in part using the web based and interactive Risk Assessment Mapping Platform (RAMP), accessed via the project website at www.mitigatehazards.com. RAMP allows interactive discovery of robust risk, vulnerability, and exposure data developed especially for Kern County. RAMP is a mapping platform built specifically for mitigation planning. It displays County/jurisdiction facilities and buildings overlaid with natural hazards layers to bring interactivity and individual discovery to the GIS analysis performed for the MJHMP. See Vol. 1 for a detailed description of RAMP. The Planning Team used RAMP in meetings and as needed to understand vulnerabilities to the City of Bakersfield. Users interactively filter facilities and buildings by natural hazard zones and/or construction characteristics.

1.4.3.2 Snapshot Exposure Maps
The included snapshot maps, displayed below in Figure 1-4 through Figure 1-10, illustrates the City of Bakersfield’s vulnerability to specific hazards. Figures include:

1.4.3.3 Past and Future Development
The City of Bakersfield is a charter city that crafts its own laws related to municipal affairs, including future development. If the City has not regulated, or the issue is not municipal in nature, the City is subject to State law. Future development may be subject to compliance with State of California planning, zoning, subdivision, and architecture laws.

The City of Bakersfield’s General Plan (GP) establishes long-range development policies. The GP is designed to help the City address issues related to land use, circulation (traffic), housing, open space, conservation, noise, and safety. The Land Use portion of the plan helps guide the City in determining the location of future development(s), including possible future annexation. In addition to the GP, the City has other plans that guide development in specific areas, including specific plans, policy plans, and ma ster plans. These plans help to shape future development and dictate the City’s Sphere of Influence (SOI). One of the central functions in these planning documents is to decrease risk of impact from natural hazards.

Development since Previous HMP
The City considered its growth since the last HMP and determined it had completed a central mitigation action and substantially decreased its vulnerability to hazards. The City installed new back-up generators for stormwater pumps, they have also implemented a seismic retrofit program of local bridges. This HMP Annex has been revised to reflect this substantial change in past development and continues to focus on avenues to better mitigate impacts from problematic past development. This is especially important as the District does not regulate future development and instead provides services and infrastructure to such development.

Future Development
City of Bakersfield is required to update building codes to meet the minimum standards to those required in the California Building Code last updated in 2019. California Building Codes provide some of the safest construction standards in the world and are meant to reduce risk t o occupants from high wind, seismic activity, landslides, flood, wildfire, and other natural hazards. In addition to California minimum develop standards, all jurisdictions belong to the NFIP, as such, all development must meet minimum flood protection standards set forth by FEMA. See Section 4.3.5 of Volume 1 for more information about past and future development in Kern County.

As the General Plan is updated and incorporates information from this HMP, City of Bakersfield staff are continually improving hazard information through these hazard mitigation plan updates. With this 2020 update, improved online mapping about natural hazards available on RAMP will inform those responsible for future development to make better decisions where and how future development occurs.

City of Bakersfield reviewed its general plans under the capability assessments undertaken for this hazard mitigation plan. See Section 1.5.1. Deficiencies revealed by these reviews are identified as mitigation actions to decrease risks to move beyond past trends.

FEMA/Cal OES Submission 05-19-2021
Kern Multi-Jurisdiction 2020 MJHMP Update

COUNTY OF KERN

1-18
The City’s municipal codes includes regulations to mitigate the impact of hazards on new and existing development, including:
▪ Drainage and stormwater retention requirements,
▪ Steep slope restrictions for new development,
▪ Waterbody buffer requirements,
▪ Floodplain management regulations,
▪ Zoning that prevents development in hazardous areas of the community such as floodplains, landslide areas, the wildland-urban interface (WUI), or other known hazard areas, and ▪ Building codes that include the most up-to-date California Fire Code, seismic standards, and many other provisions crafted to protect new construction from hazard events.

The City of Bakersfield’s current General Plan was adopted in 2002, with amendments occurring at various points since that time. Since the adoption of the General Plan and its amendments, there have been significant changes in demographics, existing conditions, land use, and economic and social trends in Bakersfield and the larger region. The beginning of a comprehensive update to the General Plan acknowledges the significant changes of the past and plans for the significant changes that will occur in the future. In addition to changes to the existing set ting, changes in data gathering and modeling capabilities have dramatically improved in the past 20 years, allowing more accurate analysis of future impacts and to better predict potential hazard impacts on the city. The comprehensive update of the General Plan will strengthen the HCP, acting as a policy tool in identifying hazards and assisting the HCP in providing guidance in hazard mitigation into the future.

Even in the event that limited development did occur within a hazard area, the municipal code sh ould ensure impacts from a hazard event are mitigated and losses are minimal. If development does occur in hazard areas, evacuation and emergency planning should take into consideration the anticipated local impacts of the hazard event, including potential interrupted services or the elimination of access.

The anticipated growth in the City will not cause significant change in vulnerability to the City for identified priority hazards.

National Flood Insurance Program (NFIP)
The NFIP makes federally backed flood insurance available to homeowners, renters, and business owners in participating communities. FEMA has prepared a detailed Flood Insurance Study (FIS) for Kern County and municipalities. The study presents water surface elevations for floods of va rious magnitudes, including the 1-percent annual chance flood and the 0.2-percent annual chance flood (the 500-YR flood).

Base flood elevations and the boundaries of the 100- and 500-YR floodplains are shown on Flood Insurance Rate Maps (FIRMs), which are the principle tool for identifying the extent and location of the flood hazard.

FIRMs are the most detailed and consistent data source available, and for many communities they represent the minimum area of oversight under their floodplain management progra m. See Section 4 of Volume 1 for general information on the NFIP.

The City of Bakersfield has participated in the NFIP since 1985. The City of Bakersfield is currently in good standing with the provisions of the NFIP. Compliance is monitored by FEMA regional staff and by the California Department of Wa ter Resources under a contract with FEMA. Maintaining compliance under the NFIP is an important component of flood risk reduction. See Table 1-6 for more information on the City’s policies and historic flood insurance claims.

1.4.4 Identify Hazard Problem Statements
As part of the mitigation action identification process, the Planning Committee for each jurisdiction identified areas of concern (aka problem statements) for their respective facilities based on the risk assessment and vulnerability analysis, utilizing the RAMP mapping and static snapshot maps . Problem statements focused on the impact, victim, or threat that the hazard could create in the jurisdiction, as described in Figure 1-11. Identifying common issues and weaknesses through these problem statements assisted the Planning Committee in understanding the realm of resources needed for mitigation.

Jurisdiction problem statements are listed in Table 1-7.

The goal is to have at least one mitigation action for every problem statement. Projects or actions have been developed to mitigate each problem identified. See Table 1-12 for a full list of mitigation actions and corresponding problem statements that they address. Each problem statement is coded with a problem number for cross-referencing between Table 1-7 and Table 1-12.

1.4.4.1 Mitigation Action Support Tool (MAST)
As a living document, hazard problem statements and mitigation activities will be updated through a web interface application developed specifically for participating jurisdictions. The Mitigation Action Support Tool (MAST) is accessible through http://mitigatehazards.com/county-of-kern/.

MAST is a web -based interactive tool that enables multiple users to search, view, enter, and update mitigation actions, ideas or projects, and other information. MAST provides participating jurisdictions and plan reviewers (Cal OES/FEMA) access to valuable mitigation information that can be leveraged by future planning or other risk reduction efforts within the County. Participating jurisdictions can update the status of their mitigation projects throughout the planning lifecycle, and this web -based tool will improve participating jurisdiction’s ability to apply for FEMA’s Hazard Mitigation Assistance (HMA) grant programs including initial grant application processes through Cal OES.

1.5 Mitigation Strategy
The mitigation strategy is the guidebook to future hazard mitigation administration, capturing the key outcomes of the MJHMP planning process. The mitigation strategy is intended to reduce vulnerabilities outlined in the previous section (a.k.a. problem statements) with a prescription of policies and physical projects. These mitigation actions should be compatible with existing planning mechanisms and should outline specific roles and resources for implementation success.

1.5.1 Capabilities Assessment
This section examines the planning and regulatory, administrative, technical, financial, educational, and outreach capabilities to augment known issues and weaknesses from identified natural hazards.

The tables in this section explore various local planning mechanisms, administrative capacity, financial capabilities, and education and outreach initiatives. The columns in each table represent deeper dives into the following questions:
▪ Is the existing planning or regulatory mechanism used currently? (Column 1, Status) ▪ Has the HMP been integrated into the planning mechanism currently so that the named mechanism is currently used in HMP planning? (Column 2, Current Mitigation Use) ▪ Is there a future opportunity to expand, improve upon, and incorporate this 2020 HMP Update into the planning or regulatory mechanism? (Column 3, Future Opportunity) The capabilities assessment is easily-digestible and based on color coding to indicate which policies and plans are adequate, need impr ovement or in which the HMP could be integrated. Each table includes a legend that explain how each one of these questions are being answered according to the color indicated:
green, yellow, and orange.

For more information on the regulatory environment su rrounding each hazard, see hazard -specific sections of Volume 1. Volume 1, Section 5.3.5 includes an extensive list of federal and state funding opportunities as well.

1.5.2 Mitigation Actions
Mitigation actions were developed based upon the
jurisdiction’s priorities, risk assessment results, and mitigation alternatives. The mitigation action
prioritization method used by all participating
jurisdictions is described in Section 5.5.1 of Volume 1.

Table 1-12 lists each priority mitigation action,
responsible party, time frame, potential funding source, implementation steps, and resources need to
implement based upon the Planning Co mmittee
consensus.

Each participating jurisdiction , including the City of Bakersfield, considered ongoing relevancy of
mitigation actions from the existing MJHMP and
retained or removed such actions while adding new
relevant actions as well. Mitigation actions were
examined for relevancy and the potential for future
implementation and then evaluated for potential
follow-up. Some mitigation actions developed during
the previous HMP effort were not included because
they were an inherent part of the HMP update process
or were not d etailed enough for implementation at a
local Jurisdiction level. the City of Bakersfield has
made significant changes to other mitigation actions
because of the updated risk assessment and
implementation strategy, to include more detail, or to
update based on current mitigation practices. Volume 1, Section 5.5.2 provides a record of County wide mitigation actions, the status, and additional notes for each action.

Table 1-12 lists each mitigation action for the City of Bakersfield. Each participating jurisdiction developed unique mitigation actions, targeted at their own unique priorities and vulnerabilities . Each mitigation action identifies the responsible party, time frame, potential funding source, implementation steps and resources needed to implement these priority mitigation actions. As a living document, hazard problem statements and mitigation activities will be updated through MAST. The detail in Table 1-12 meets the regulatory requirements of FEMA and DMA 2000.
