2025 Urban Water Management Plan

City of Glendale

CHAPTER 1

URBAN WATER MANAGEMENT PLAN INTRODUCTION AND OVERVIEW

LAY DESCRIPTION - INTRODUCTION

An urban water supplier is defined (pursuant to Section 10617 of the California Water Code1) as “a supplier, either publicl y or privately owned, prov iding water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually. An urban water supplier includes a supplier or contractor for water, regardless of the basis of right, which distributes or sells for ultimate resale to customers.”

The City of Glendale (City), or Glendale Water and Power (GWP ), is classified as an urban water supplier because it serves more than 3,000 customers (i.e. individual metered accounts) and it supplies more than 3,000 acre-feet of water annually to its customers for municipal purposes.

In accordance with the “Urban Water Management Planning Act”, which was enacted by the California Legislature in 1983, every urban water supplier (including the City) is required to prepare and adopt an Urban Wate r Management Plan (UWMP), periodically review its UWMP, and incorporate updated and new information into an updated UWMP at least once every five years.

The City’s most recent update was its 2020 UWMP (or 2020 Plan) which was submitted to, and approved by, the California Department of Water Resources (DWR). Urban water suppliers (including the City) are required to complete and submit their 2025 UWMPs to DWR by July 1
st, 2026.

1 References to CWC Sections in this 2025 UWMP were obtained from https://leginfo.legislature.ca.gov/

2025 Urban Water Management Plan

City of Glendale

The current requirements for preparing the UWMP are included in California Water Code (CWC) Sections 10608 through 10657. The City’s 2025 UWMP (or 2025 Plan) was prepared consistent with the CWC and the recommended organization provided in DWR’s Final “Urban Water Managemen t Plan Guidebook 2025” (Final 2025 UWMP Guidebook), dated January 2026.

The UWMP provides urban water suppliers (including the City) with a reliable management action plan for long-term resour ce planning to ensure adequate water supplies are available to meet existing and future water supply needs. In addition, the 2025 Plan incorporates water supply reliabilit y determinations resulting from potential prolonged drought, regulatory revisions, and/or changing climatic conditions.

The City’s 2025 Plan consists of the following Chapters:

Chapter 1 Urban Water Management Plan Introduction and Overview Chapter 2 Plan Preparation
Chapter 3 Service Area Descriptions
Chapter 4 Water Use Characterization
Chapter 5 SB X7-7 Baselines, 2020 Targets, and 2025 Reporting Chapter 6 Normal Year Water Supply Characterization
Chapter 7 Water Service Reliability and Drought Risk Assessment Chapter 8 Water Shortage Contingency Plan
Chapter 9 Demand Management Measures
Chapter 10 Plan Adoption, Submittal, and Implementation

A lay description for each of these Chapters is presented below.

2025 Urban Water Management Plan

City of Glendale

LAY DESCRIPTION – CHAPTER 1

URBAN WATER MANAGEMENT PLAN INTRODUCTION AND OVERVIEW

Chapter 1 (Urban Water Management Plan Introduction and Overview) of the City’s 2025 Plan discusses and provides the following:

 An overall lay description of the 2025 Plan, including California Water Code and Urban Water Management Plan Act requirements, is provided. The City is required to prepare an Urban Water Management Plan.
 The City’s 2025 Plan was prepared consis tent with the recommended organization provided in DWR’s Final “Urban Wa ter Management Plan Guidebook 2025”, dated January 2026. A description regardi ng the organization of the 2025 Plan, including a summary of each Chapter, is provided. The City’s Water Shortage Contingency Plan (discussed in Chapter 8) is also included in the 2025 Plan.  The 2025 Plan incorporates DWR’s wate r use and supply tables (standardized Submittal Tables) for the reporting and submittal of UWMP data. Relevant Submittal Tables are included at the end of each Chapter in this 2025 Plan and in Appendix A.
 The City’s coordination efforts with other planning agencies are discussed, including coordination efforts with Me tropolitan Water District of Southern California (MWD) and the Los Angeles Department of Water and Power.  The City’s eligibility to receive grant s and loans administered by the State of California and/or DWR, as a result of preparing the 2025 Plan, is discussed.  Information is provided which demonstrates the City’s prior, continued, and projected reduction on imported water supplies obtained (either directly or indirectly) from the Sacramento-San Joaquin Delta (Delta). The City has reduced its reliance on the imported water suppl ies for Calendar Year 2020 and Calendar

2025 Urban Water Management Plan

City of Glendale

Year 2025. In addition, the City is projected to continue reducing its reliance on the imported water supplies through Calendar Year 2050.
 The checklist developed by DWR and used by the City to incorporate the specific UWMP requirements is discussed. The completed checklist is provided in Appendix B.

UPDATED GUIDANCE FOR 2025 URBA N WATER MANAGEMENT PLANS The City’s 2025 Plan was prepared consis tent with the recommended organization provided in DWR’s Final “Urban Wate r Management Plan Guidebook 2025”, dated January 2026. DWR provided the following updated guidance for the preparation of the 2025 Plans (in comparison to the preparation of the 2020 Plans):

 There have been minor changes to the Water Code since the 2020 Plans were submitted; primarily, several definitions have been added (none of these change the requirements for 2025 Plans).
 DWR and the State Water Re sources Control Board are using the same criteria to determine when a water supplier with multiple Public Water Systems is considered an Urban Water Supplier subject to UWMP requirements.  DWR has updated its submitta l tables to reflect the current reporting year, improve accuracy of reporting, and more clearly identify information required by Water Code and optional information.
 There has been no change to the Wa ter Code regarding water loss standard reporting since the 2020 Pl ans were submitted. Howe ver, water suppliers can report progress toward compliance with their 2028 Water Loss Standard in the 2025 Plans (see Table 4-6).
 The State Water Resources Control Board has adopted regulations for the use of direct potable reuse (DPR) since the 2020 Plan reporting. To allow for reporting

2025 Urban Water Management Plan

City of Glendale

of DPR, minor changes have been made to the supply and demand tables in the 2025 Plans.
 While projections for lower-income hous ing were required in the 2020 Plans, additional guidance has been provided for optional reporting of the method used to project water use for lower-income housing.
 In previous years, the guidance for repo rting water placed in to storage did not differentiate between long-term storage (i.e., water placed into storage one year but extracted in a future year) and short- term storage (i.e., water that is placed into storage and extracted the same year ). When a water s upplier reports water placed into storage and then reports it was retrieved in the same year (short-term storage) it can cause a double counting error. Additional guidance has been provided recommending that water suppliers do not report wate r into and out of short-term storage.

SUBMITTAL TABLES

OPTIONAL PLANNING TOOL

DWR has created an optional “Planning Tool Wo rksheet” for water suppliers to review and assess monthly water use trends. DW R has deemed the tool as optional and the City is not required by DWR to use the tool.

RECOMMENDED UWMP ORGANIZATION

The City’s 2025 Urban Water Management Pl an (2025 Plan) was prepared consistent with the recommended organization provided in DWR’s Final “Urban Water Management Plan Guidebook 2025” (Final 2025 UWMP Guidebook), dated January 2026. The City’s 2025 Plan consists of the following Chapters:

Chapter 1 Urban Water Management Plan Introduction and Overview Chapter 2 Plan Preparation
Chapter 3 Service Area Description
Chapter 4 Water Use Characterization
Chapter 5 SB X7-7 Baselines, 2020 Targets, and 2025 Reporting Chapter 6 Normal-Year Wate r Supply Characterization
Chapter 7 Water Service Reliab ility and Drought Risk Assessment Chapter 8 Water Shortage Contingency Plan
Chapter 9 Demand Management Measures
Chapter 10 Plan Adoption, Submittal, and Implementation

Pursuant to CWC requirements, the City’s 2025 Plan incorporates DWR’s water use and supply tables (standardized Submittal Tables ) for the reporting and submittal of UWMP data. DWR’s standardized Submittal Tables are provided within the body of the 2025 Plan text as well as in Appendix A.

2025 Urban Water Management Plan

City of Glendale

The City’s 2025 Plan also provides su pporting documents ( appendices) including notification letters of the Plan update, publ ic notice of the Pl an hearing, and adoption resolution from the City’s governing body. Further discussions regarding these supporting documents are provided within the individual Chapters of the City’s 2025 Plan.

UWMPS IN RELATION TO OTHER EFFORTS

The City’s 2025 Plan was prepared in coordination with planning agencies including the Los Angeles County Department of Regi onal Planning and the Southern California Association of Governments (SCAG). In addition, t he City’s 2025 Plan was prepared using management documents incl uding the County of Los Angeles 2025 “All- Hazards Mitigation Plan”.

The City is a sub-agency of MWD, a wholesale water agency. MWD prepared a 2025 Plan which is incorporated in the City’s 2025 UWMP by reference. In addition, the City provided its 2025 UWMP to MWD which includes water use projections in five-year increments for a normal year, a single dry year, and a five consecutive year drought over the next 25 years.

SPECIFIC CONSIDERATIONS

1.4.1.1 DEMONSTRATION OF CONSISTENCY WITH THE DELTA PLAN

FOR PARTICIPANTS IN COVERED ACTIONS
Pursuant to DWR, an urban water supplier that anticipates participat ing in or receiving water from a proposed project (or “covered action”) such as a multi-year water transfer, conveyance facility, or new diversion that involves transferring water through, exporting water from, or using water in the Sacrament o-San Joaquin Delta (Delta) should provide

2025 Urban Water Management Plan

City of Glendale

information in their Plans for use in demonstrating consistency with Delta Plan Policy WR P1, “Reduce Reliance on the Delta Through Improved Regional Water Self-Reliance”. In addition, pursuant to California Code of Regulations, Title 23, § 5003:

(c)(1) Water suppliers that have done all of the following ar e contributing to reduced reliance on the Delta and impr oved regional self-reliance and are therefore consistent with this policy:

(A) Completed a current Urban or Agricultural Water Management Plan (Plan) which has been reviewed by t he California Department of Water Resources for compliance with the applicable requirements of Water Code Division 6, Parts 2.55, 2.6, and 2.8;

(B) Identified, evaluated, and commenced implementation, consistent with the implementation schedule set forth in the Plan, of all programs and projects included in the Plan that are locally cost effective and technically feasible which reduce reliance on the Delta; and

(C) Included in the Plan, commencing in 2015, the expected outcome for measurable reduction in Delta reliance and improvement in regional self- reliance. The expected outcome for measurable reduction in Delta reliance and improvement in regional self-reli ance shall be reported in the Plan as the reduction in the amount of water used, or in the percentage of water used, from the Delta watershed. Fo r the purposes of reporting, water efficiency is considered a new source of water supply, consistent with Water Code section 1011(a).

The City has reduced its reliance on the impor ted water supplies for calendar year (CY) 2015, CY 2020, and CY 2025. In addi tion, the City is project ed to continue reducing its reliance on the imported water supplies th rough CY 2050. A further discussion which demonstrates the City’s measurable r eduction in imported water reliance and improvement in regional self-reliance is provided in Appendix C.

1.4.1.2 PERMITTING FOR OCEAN DESALINATION PROJECTS
The City is currently not c onsidering the develo pment of a desalinated water project.

However, as discussed in Section 6.2.6, there may be opportunities for use of desalinated

2025 Urban Water Management Plan

City of Glendale

ocean water as a potential water supply s ource in the future, if needed, through coordination with other agencies that have ocean desalination programs.

DEPARTMENT OF WATER RESOURCES’ REVIEW PROCESS
Section 10.5 discusses the process for a water supplier to submit the completed 2025 Plan to DWR, including electronic submittal through DWR’s online Water Use Efficiency Data (WUEdata) portal. DWR will subsequently re view the 2025 Plans to ensure that they address the California Water Code requir ements. Following DWR’s review, water suppliers will be notified of the results of the review via a formal review letter. These review letters will also be available to the public on DWR’s WUEdata portal. In cases where DWR finds that a Plan does not properly address item(s) in the Water Code, DWR will reach out to the water supplier to discuss needed corrections and correction procedures.

2025 Urban Water Management Plan

City of Glendale

 The City’s notification process to the cities and county within which the City provides water supplies to, is discussed.

As discussed in Section 1.3, the City’s 2025 Plan was prepared consistent with the recommended organization provided in DWR’s Final 2025 UWMP Guidebook.

Pursuant to CWC requirements, the City’s 2025 Plan incorporates DWR’s water use and supply tables (standardized Submittal Tables ) for the reporting and submittal of UWMP data.

BASIS FOR PREPARING A PLAN

CWC 10617.

"Urban water supplier" means a supplier, either publ icly or privately owned, providing water for municipal purposes either directly or indirect ly to more than 3,000 customers or supplying more than 3,000 acre-feet of water annually. An urban wate r supplier includes a supplier or contractor for water, regardless of the basis of right, which distributes or sells for ultimate resale to customers.

This part applies only to water supplied from public water systems subject to Chapter 4 (commencing with Section 116275) of Part 12 of Division 104 of the Health and Safety Code.

CWC 10618.12.

(t) “Urban retail water supplier” means a water supplie r, either publicly or privately owned, that directly provides potable municipal water to more than 3,000 end users or that supplies more than 3,000 acre-feet of potable water annually at retail for municipal purposes.

(w) “Urban wholesale water supplier” means a water supplier, either publicly or privately owned, that provides more than 3,000 acre- feet of wa ter annually at wholesale for potable municipal purposes.

CWC 10620.

(b) Every person that becomes an urban water su pplier shall adopt an urban water management plan within one year after it has become an urban water supplier.

CWC 10621.

(a) Each urban water supplier shall update its plan at least once every five years on or before July 1, in years ending in six and one, incorporat ing updated and new information from the five years preceding each update.

2025 Urban Water Management Plan

City of Glendale

The City’s 2025 Plan was prepared in a ccordance with the UWMP Act which was established in 1983. The UWMP Act requi res every “urban water supplier” to prepare and adopt a Plan, to periodically review its Plan at least once every five years and make any amendments or changes which are indica ted by the review. An “Urban Water Supplier” is defined as a supplier, either public ly or privately owned, providing water for municipal purposes either directly or indirectly to more than 3,000 customers or supplying more than 3,000 acre-feet (AF) of water annually.

Section 10621(a) of the CWC states, “Each urban water supplier shall update its plan at least once every five years on or before July 1, in years ending in six and one, incorporating updated and new information from the five years preceding each update”.

As a result, DWR requires the 2025 Plans be submitted by July 1, 2026.

The City is an “urban water supplier” pursuant to Section 10617 of the CWC and directly serves potable water to more than 3,000 cu stomers and supplies more than 3,000 acre- feet per year (AFY) at retail for municipal purposes. The City’s 2025 Plan is an update to the City’s 2020 Plan.

SUPPLIERS WITH BOTH WH OLESALE AND RETAIL SALES

The City is a retail water supplier (and not a wholesale water supplier). The City’s 2025 Plan was prepared based on the CWC requirements pertaining to retail water suppliers.

The City relies on water supplies from w holesale water suppliers which are discussed in Section 2.4.1.

2025 Urban Water Management Plan

PUBLIC WATER SYSTEMS

California Health and Safety Code 116275.

(h) "Public water system" means a system for the provision of water for human consumption through pipes or other construc ted conveyances that has 15 or more service connections or regularly serves at least 25 individuals daily at least 60 days out of the year.

Pursuant to CWC requirement s, the City’s 2025 Plan incorporates DWR’s standardized tables for the reporting and submittal of UWMP data. The standardized Submittal Tables are provided within the body of the 2025 Plan te xt as well as in Appendix A. The City also submitted the UWMP data (from the Submittal Tables) electronically through DWR’s Online Submittal Tool.

In addition, the City is a Public Water Sy stem and is regulated by the State Water Resources Control Board - Division of Drinking Water (SWRCB-DDW). The SWRCB- DDW requires water agencies provide the number of connections, water usage, and other information annually. The information provided to SWRCB-DDW indicates the City serves potable water to more than 3,000 customers and supplies more than 3,000 AFY. Table 2-1 provides the City’s Public Water System name and number. As indicated in Table 2- 1, the City serves only a single Public Water System.

INDIVIDUAL OR REGIONAL PLANS
As shown in Table 2-2, the City’s 2025 Plan is an “Individual UWMP”. The City has developed its 2025 Plan reporting solely on its service area to address all requirements of the California Water Code, including wate r use targets and baselines pursuant to SB X7-7 Water Conservation Act of 2009 reporting (discussed further in Chapter 5).

A discussion of the City’s sources of s upply, how those sources may be impacted by climate change, and the proac tive actions the City and other local/regional water managers may take to address the potential climate change on water supplies is provided in Section 4.5.

SERVICE AREA POPULA TION AND DEMOGRAPHICS

SERVICE AREA POPULATION

CWC 10631.

(a) 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.

The City provides water service to an area with a current population of 189,652. Table 3- 1 presents the current and proj ected population of the area encompassed by the City’s service area from CY 2025 to FY 2050. The City is projected to have a population of 204,765 by FY 2050.

A GIS analysis using census tracts was performed to estimate the current population (CY 2025) within the City’s service area. The City’s service area is comprised of individual census tracts which represent smaller st atistical areas for which population data is available. The smaller census tracts were combined to more accurately represent the total area within the City’s service area.

Current census tract information was obt ained in a GIS format from the advanced demographics dataset developed by Esri which includes source ma terial supplied by

2025 Urban Water Management Plan

City of Glendale

the U.S. Census Bureau and the U.S. Cens us Bureau's American Community Survey.

The City’s service area boundary in a GIS format was overlayed on the census tract GIS layer. Each census tract located within t he City’s service area was identified (including the entire census tract or a portion of). For a census tract located entirely within the service area, the entire population (i.e. 100 percent) associated with the census tract was incorporated. For a census tract located parti ally within the servic e area, the portion (or percentage) of the census tract located geographically within the service area was determined through GIS. The percentage wa s then applied to the census tract’s population in order to estimate the population of the census tract within the service area.

The total population within the City’s service area was then estimated based on the sum of the populations within these census tracts.

The projected total population within the Ci ty’s service area was based on growth rate projections included in the Southern Califo rnia Association of Governments (SCAG) “Connect SoCal 2024, Demographics and Growth Forecast” report dated April 2024. The SCAG report incorporates demographic trends, existing land use, general plan land use policies, and input and projections through the year 2050 from the Department of Finance (DOF) and the U.S. Census Bureau for countie s, cities and unincorporated areas within Southern California. Annual growth rate proj ections within the City’s service area were estimated based on the SCAG report and appli ed to the City’s current population to estimate projected populations through 2050.

The City’s service area is almost built out with predominantly si ngle and multi-family residential units and some co mmercial, institutional, and industrial establishments.

Moving forward, the City will continue planning for the Regional Housing Needs Assessment (RHNA) allocations and future planned developments including the addition of apartment units and accessory dwelling units (ADUs) as the means of affordable housing.

2025 Urban Water Management Plan

City of Glendale

Pursuant to the California State Housing Law, every jurisdiction (including the City of Glendale) is required to plan for its RHNA allocation in the Housing Element of its General Plan. RHNA is a representation of future housing needs for all income levels in a jurisdiction. SCAG’s “6th Cycle Final RHNA Allocation ” was adopted March 2021 (and modified in July 2021) and covers the planning period from October 2021 through October 2029. The total RHNA allocation of housing within the City of Glendale through 2029 is 13,425 units (including 3,439 “very-low” income units, 2,163 “low” income units, 2,249 “moderate” income units, and 5,574 “above moderate” income units). The City of Glendale must identify adequate sites and establish policies and programs that will accommodate the estimated growth; however the City of Glendale is not obligated to produce, construct, or develop these allocated units.

OTHER SOCIAL, ECONOMIC, AND DEMOGRAPHIC FACTORS

CWC 10631.

(a) Describe the service area of the supplie r, including… other social, economic, and demographic factors affecting the supplier’s water management planning.

No other demographic factors affect the City’s water management planning. However, increased population will have an impact on water demand.

The City reviewed the current and projected land uses within its service area during the preparation of this 2025 Plan. Information r egarding current and projected land uses is included in the City of Glendale’s General Plan. The existing la nd uses within the City’s service area include residential (single-family and multi-family), commercial, industrial, institutional, and open space. The projected land uses within the City’s service area are expected to remain similar to the existing land uses. In addition, although mostly built-out, the projected population within the City’s service area is anticipated to increase (as discussed in Section 3.4). A discussion of t he existing and projected water uses for the individual water use sectors within the City’s service area, which includes the different land uses, is provided in Sectio n 4.2. As discussed in Secti on 2.4, the City coordinated the preparation of the 2025 Plan with the Cities of Burbank, Los Angeles, and Pasadena, and other agencies.

As discussed in Section 3.4, the City obtained data from the Southern California Association of Governments document entitled “Connect SoCal 2024, Demographics and Growth Forecast”, dated April 2024. Projected populations in the City’s service area were based on growth rate projections developed by SCAG. The data provided by SCAG incorporates demographic trends, existing land use, general plan land use policies, and input and projections through the year 2050 from the Department of Finance and the U.S.

These water use sectors include single-family residential, multi-family, commercial, and institutional (and governmental), landscape, and industrial . Individual descriptions for these water use sectors are provided in Section 4.2.1.
 The City’s total water demands (including potable and recycled water) over the past 15 years have ranged from 21,311 AFY to 29,520 AFY, with an average of 25,164 AFY. The City currently measures its water use through meter data and billing records.
 The City conducts an annual water loss audit to identify distribution system water losses. Water losses can result from pipeline leaks and inaccurate metering due to faulty meters. Water loss estimates are incorporated into the City’s projected water demands.
 The City’s current and projected wa ter demands are provided in five-year increments over the next 25 years are pr ovided (through Calendar Year 2050) as shown on Table 4-3.
 The City’s water demand projections in corporate passive savings from water savings which are the result of implem entation of codes, water conservation standards, and/or ordinances.

2025 Urban Water Management Plan

City of Glendale

 The projected water demands for lower income households are identified and are included in the City’s total projected water demands
 The City’s sources of water supply and how those sources may be impacted by climate change are discussed. The proac tive actions the City and other local/regional water managers may take to address the potent ial climate change impacts on water supplies are also discussed.

NON-POTABLE VERSUS POTABLE WATER USE

The Water Code requires a description and quantific ation of water uses within the City’s service area, including both non-potable and potable water. Recycled water (non-potable) uses are addressed in Secti on 6.2.5; however, a summary is provided in Table 4-1 and Table 4-2. Furthermore, Chapter 4 addresses the City’s potable water demands.

OPTIONAL WATER-USE SECTORS IN ADDITION TO THOSE

LISTED IN WATER CODE

The City’s service area does not include other water demand sectors which are not listed in the California Water Code (including exchanges, transfers, wetlands or wildlife habitat, and surface water storage).

PAST WATER USE

Chapter 6 provides a discussion of the sources of water supply the City uses to meet its water demands. Section 6.1 provides a tabulat ion of the City’s historical annual water demands for each water supply source. Over th e past 15 years, the City’s total water demands have ranged from 21,311 AFY to 29,520 AFY, with an average of 25,164 AFY.

In addition, the City previously experienced a five consecutive year drought within its service area from CY 2011 to CY 2015. The Ci ty reviewed its historical water demands to determine the projected water demands and water supply reliability (discussed in Chapter 7). The City is able to provide sufficient water supplies to meet the projected water demands of its customers, including during a five consecutive year drought period.

DWR has created an optional “Planning Tool Wo rksheet” for water suppliers to review and assess monthly water use trends. DW R has deemed the tool as optional and the City is not required by DWR to use the tool. Section 6.1 provides a tabulation of the City’s historical annual water uses for each water supply source. During the past 15 years, the City experienced a five consecutive year drought within its service area from CY 2011 to CY 2015. Historical records indicate t he City’s annual water demands had been greater prior to CY 2011. The City has been able to provide sufficient water supplies to its customers, including during l ong-term droughts and years with historically high water demands. In addition, the City has been able to provide water service to meet maximum day water demands for these years, includi ng during the summer months. A further discussion regarding the reliabi lity of the City’s water s upply sources is provided in Chapter 7.

2025 Urban Water Management Plan

City of Glendale

The City’s projected water demands are provided in five-year increments over the next 25 years (through CY 2050 in Table 4-2. The City’s projected water demands and water supplies during a normal year, a single dry year, and a five consecutive year drought are provided in Chapter 7. The projected water demands for eac h of the City’s water use sectors are provided in Table 4-2. As discussed in the following Section, the City’s water demand projections incorporate “passive savings” which are the result of implementation of codes, standards, and/or ordinances.

4.2.5.4 RETAIL ONLY
The City’s total water demands were projected based on a review of the “2020 Water Use Target” pursuant to SB X7-7 calculations (d iscussed in Section 5. 2), current water use factors based on recent water demands , Urban Water Use Objective standards (discussed in Section 5.2.6), and the total population projections based on land use trends within the City (discussed in Section 3.4). The projected water demands for the water use sectors were based on the percentage breakdown of water demands from each individual water use sector in CY 2025 (the percentages were then applied to the projected total water demands). A discussion of the City’s water supplies from MWD, a wholesaler, are discussed in Section 6.2. As discussed in Section 2.4.1, the City has coordinated its water demand projections with MWD for each water use sector.

The City’s water demand projections incorpor ate water savings from “passive savings” which are the result of implementation of codes, standards, and/or ordinances. The City’s Municipal Code Chapter 13.36 “W ater Conservation” includes methods for current and ongoing reduction in water use and water wast e. The City’s Ordinance No. 5660 (2009) and Ordinance No. 5854 (2015) modified the City’s Municipal Code Chapter 13.36. Prior to adoption of Ordinance No. 5660, the City’s water use rate ranged from approximately 139 gallons per capita day to 149 gallons per capita day (from CY 2000 through CY 2008).

As identified in Section 5.2.2, the City’s actual water use rate during CY 2020 was 104

2025 Urban Water Management Plan

City of Glendale

gallons per capita per day which is a decrease of up to 45 gallons per capita per day from the recent historical water use and includes passive savings. The City’s projected water demands, incorporate water use targets less than its established SB X7-7 water use target for 2020 and incorporate ongoing water passive savi ngs and reduced water use.

As indicated in Table 4-3, estimated futu re water savings have been considered as part of the City’s water use projections.

4.2.5.5 LOWER-INCOME HOUSEHOLDS

CWC 10631.1.

(a) The water use projections required by Section 10631 shall include projected water use for single-family and multifamily residential housing needed for lower income households, as defined in Section 50079.5 of the Health and Safety Code, as identified in the housing element of any city, county, or city and county in the service area of the supplier.

(b) It is the intent of the Legislat ure that the identification of projected water use for single-family and multifamily residential housing for lower in come households will assist a supplier in complying with the requirement under Section 65589.7 of the Government Code to grant a priority for the provision of service to housing units affordable to lower income households.

California Health and Safety Code 50079.5.

(a) "Lower income households" means persons and families whos e income does not exceed the qualifying limits for lower income families… In the event the federal standards are discontinued, the department shall, by regulatio n, establish income limits for lower income households for all geographic areas of the state at 80 percent of area median income, adjusted for family size and revised annually.

The City’s water demands projections prov ided in Table 4-2 include projected water demands for lower income households as part of the single-family and multi-family water use categories. A lower income household is defined as a household with an income less than 80 percent of the “area median income”, adjusted for family size. For the purpose of this evaluation, the entire Los Angeles Coun ty was used for the “area median income”.

The total number of lower income households within the City’s service area was estimated

2025 Urban Water Management Plan

City of Glendale

based on billing records provided by the City, a review of the City of Glendale’s General Plan, a review of median household income range statistics provided by the US Census Bureau ( https://data.census.gov/cedsci/), and a review of GIS maps of Disadvantaged Communities2 (DACs), including block groups, tracts, and places, provided by DWR. The estimated number of lower inco me households located within the City’s service area is approximately 42.2 percent of the total number of households. As indicated in Table 4-2, the total projected residential (single family and multi-family) water demands within the City in CY 2050 is estimated at about 18,088 AFY. Based on a 42.2 percent use factor of total residential water demands, the proj ected water demand for lower income households will be about 7,629 AFY by CY 2050. The projected water demands for lower income households were included in the City’s total projected water demands, as indicated in Table 4-3.

4.2.5.6 CLIMATE CHANG E CONSIDERATIONS

CWC 10630.

It is the intention of the Legislatur e, in enacting this part, to permit levels of water management planning commensurate with the numbers of customers served and the volume of water supplied, while accounting for impacts from climate change.

CWC 10635.

(b) Every urban water supplier shall include, as part of its urban water management plan, a drought risk assessment… (and) shall include each of the following…

(4) Considerations of the historical drought hy drology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria.

2 GIS information for DACs is based on data from the US Census showing census block groups, tracts, and places identified as disadvantaged communities (less than 80 percent of the State's median household income) or severely disadvantaged communities (less than 60 percent of the State's median household income)

2025 Urban Water Management Plan

City of Glendale

Climate is defined as “the average course or condition of the weather at a place usually over a period of years as ex hibited by temperature, wi nd velocity and precipitation 3”. A change in the climate which produces a greate r amount of precipitation (i.e. more runoff and/or snowpack) and lower temperatures is generally a benefit to water supplies.

However, drought conditions which may result in decreased precip itation, decreased runoff, and increased temperature may adversely affect an urban water supplier’s ability to meet demands by potentia lly impacting supplies. Consequent ly, the focus of impacts of climate change is on these adverse consequences.

Section 6.2 of this Plan describes the Ci ty’s sources of water supply, management practices associated with those sources, and the long-term reliability of those sources.

Section 7.3 includes a Drought Risk Assessment which considers the potential impacts of climate change to the City’s water supply sources. C hapter 8 provides a detailed discussion of the City’s Water Shortage Cont ingency Plan, including but not limited to, the six standard water shortage levels in the event climate change results in a reduction to water supplies associated with a peri odic drought condition. The following is a discussion of the City’s sources of supply, how those sources may be impacted by climate change, and the proactive actions the City and other local/regional water managers may take to address the potential climate change impacts on water supplies.

Imported Water Supplies

The City is a sub-agency of MWD which deli vers State Water Project water supplies.

MWD has prepared a 2025 Urban Water Management Plan which includes a discussion of the reliability of its water supplies and the impacts of climate change, and is incorporated by reference in this Plan. The following is a brief summary of MWD’s efforts:

3 www.merriam-webster.com

2025 Urban Water Management Plan

City of Glendale

Resource Planning

 MWD has established the Robust Decision Making (RDM) approach to identify vulnerabilities to its water supplies. Climate change information was applied to MWD’s simulated water supply scenarios to demonstrate the vulnerability of water supplies to climate change.

 MWD altered the inflow hydrology sc enarios on the Colorado River simulation model to reflect modified inflow to MWD’s Colorado River aqueduct.

Knowledge Sharing and Research Support

 MWD is an active and founding member of the Water Utilit y Climate Alliance (WUCA) which includes 12 nationwide par tners collaborating on climate change considerations. As such, MWD shares agency actions on climate change and adaptation. WUCA has also released nu merous research papers on climate change.

Implementation of Programs and Policies

 MWD’s programs include the use of solar energy, use of ride share programs, and reduction of greenhouse emissions. Collecti vely these actions are intended to impact the effects of climate change.

Groundwater Supplies

The City relies on groundwater produced from the San Fernando and Verdugo Basins, part of the Upper Los Angeles River Area (ULARA) groundwater basins, as discussed in

2025 Urban Water Management Plan

City of Glendale

Section 6.2.2. The San Fernando and Verdugo Basins is actively managed by the ULARA Watermaster and those management activities are described in detail in Section 6.2.2.

Recognizing the potential im pacts of climate change on the San Fernando Basin and Verdugo Basin groundwater supplies (decreas ed local runoff and r eplenishment, along with increased groundwater production, may lead to decreased groundwater levels), the City reviewed the climate tools available on the California Energy Commission’s Cal- Adapt website (
https://cal-adapt.org/) to identify potential future climate change cycles for the San Fernando and Verdugo Basins. The Cal- Adapt website has been developed by the Geospatial Innovation Facility at the University of California, Berkeley with funding and advisory oversight by the California Energy Commission and California Strategic Growth Council.

To address the uncertainty in future greenhouse gas emissions, Cal-Adapt has developed a Representative Concentration Pathway 4. 5 (RCP 4.5) scenario and a Representative Concentration Pathway 8.5 (RCP 8.5) scenario. RCP 4.5 represents a scenario in which greenhouse gas emissions peak around 2040, t hen decline and stabilize. RCP 8.5 represents a scenario in which emissions continue to strongly rise through 2050 and plateau around 2100. RCP 4.5 is a “medium” emissions scenario that models a future in which there is an effort made by societies to reduce greenhouse gas emissions, whereas RCP 8.5 is a “business-as-usual” scenario. For the City’s climate change analysis, the RCP 4.5 scenario was selected.

The Cal-Adapt climate tools also incorporate several General Circulation Models (GCMs), which represent physical processes in the atmosphere, ocean, and land surface. These GCMs projected future climates under conditi ons such as warm/dry, cooler/wetter, and average simulations. For the City’s climate change analysis, the average condition GCM (CanESM2) was selected.

2025 Urban Water Management Plan

City of Glendale

The climate tools available on the Cal-Adapt website were used to simulate projected annual precipitation and annual average maximum temperature in the San Fernando and Verdugo Basins. An electronic boundary of the San Fernando and Verdugo Basins was submitted online through the Cal-Adapt website in a “KML” file format (i.e. Google Earth format) and data using several of the available climate tools was generated.

Based on the data generated by the Cal-Adapt simulations (see Appendix E), the average annual rainfall in the San Fe rnando and Verdugo Basins is pr ojected to be 25.1 inches through 2099, compared to historical aver age of 23.3 inches (from 1961 through 1990).

In addition, the average maximum temperature is projected to be 78.9 degrees Fahrenheit compared to a historical average of 72. 7 degrees Fahrenheit. Although there may be more precipitation in the future, it may be more likely to fall as rainfall compared to snowfall. The simulations do not denote the duration or intensity of storms contributing to the annual precipitation. Notwithstandi ng, the San Fernando and Verdugo Basins watershed includes an interconnected series of dams, reservoirs and replenishment basins to capture stormwater runoff. Consequent ly, most if not all precipitation (whether it is rain or snowfall) likely will be captured for use in the San Fernando Basin and Verdugo Basin area and not adversely impacted by a potentially higher average annual temperature.

DISTRIBUTION SYST EM WATER LOSS

CWC 10631.

(d)(3)(A) The distribution system water loss shall be quantified for each of the five years preceding the plan update, in accordance with rules adopted pursuant to Section 10608.34.

(B) The distribution system wate r loss quantification shall be reported in accordance with a worksheet approved or developed by the department through a public process. The water loss quantification worksheet shall be based on the water system balance methodology developed by the American Water Works Association.

2025 Urban Water Management Plan

City of Glendale

(C) In the plan due July 1, 2021, and in each updat e thereafter, data shall be included to show whether the urban retail water supplier met the distribution loss standards enacted by the board pursuant to Section 10608.34.

PREVIOUS FIVE YEARS DI STRIBUTION SYSTEM LOSSES

Distribution system water losses represent the potable water losses from the pressurized water distribution system and water storage facili ties, up to the point of delivery to the customers. Sources of distri bution system water loss can incl ude: inaccurate metering due to faulty meters; water us e not metered such as firefi ghting, flushing of the water system; and pipeline leaks.

The California Water Code Section 10608.34 requires “On or before October 1, 2017, and on or before October 1 of each year thereafter, each urban retail water supplier shall submit a completed and validated water loss audit report for the previous calendar year or the previous fiscal year...” The water loss audits must follow American Water Works Association (AWWA) guidance and be validated by a certified water audit validator. The City has completed the annual water loss audit process through January 1, 2026, as required by the California Water Code. As s hown in Table 4-5, the City has completed water loss audits for the past five years re presenting calendar years 2020, 2021, 2022, 2023, and 2024. The City’s water loss audits were prepared and validated pursuant to DWR requirements. The annual water loss audit reports submitted by retail water agencies in California, including the City , are available on DWR’s WUEdata website (
https://wuedata.water.ca.gov/awwa_plans).

The City’s annual water loss audits identify real water losses (e.g. leaks and main failures) and apparent water losses (e.g. customer me ter inaccuracies, systematic data handling errors in customer billing systems, and unauthorized consumption). The City’s distribution system water losses are based on the sum of the real and apparent water losses. Over the past five years, the City’s average distribution system water losses represent

2025 Urban Water Management Plan

City of Glendale

approximately 3.6 percent of its total water demands. This average water loss factor was incorporated into the City’s total potable water demand projections (Tables 4-2 and 4-3).

PROGRESS TOWARD MEETING TH E WATER LOSS PERFORMANCE

STANDARD

Consistent with the California Code of R egulations, Title 23, Sections 980 through 986, retail water suppliers are required to co mply with Real Water Loss Performance Standards by January 1, 2028 (pursuant to SWRCB requirements). Until then, a supplier may, when calculating its Urban Water Use Objective (discussed further in Section 5.2.6), use real losses reported in the water loss audits provided to the Department of Water Resources (discussed in Section 4.3. 1), rather than the standard-based budget calculated according to the equation described Section 970 of the California Code of Regulations.

Pursuant to the California Wa ter Code Section 10631(d)(3)(C), a retail water supplier is required to provide data in its 2025 Plan demonstrating whether the retail water supplier met its Water Loss Performance Standard. T he California Code of Regulations includes the following methods for compliance:

• Retail suppliers may have met their Real Water Loss Performance Standard if their 2025 or 2026 annual water loss audits (currently not available) show actual real water loss at or below the standard (California Code of Regulations Section 981[b]). • Retail suppliers may still meet the Real Water Loss Performance Standard if, by January 1, 2028, their 2027 annual water loss audit shows actual real water loss at or below the standard (California Code of Regulations Section 981[a] and [b]). • Apparent Water Loss Performance Standards are evaluated at the time compliance with the Real Water Loss Performance St andard is assessed (California Code of Regulations Section 981[d]).

2025 Urban Water Management Plan

City of Glendale

The City’s 2025 water loss audit is due by January 1, 2027 and was not available during the preparation, completion, and submittal of the City’s 2025 Plan. However, Table 4-6 presents the City’s Real and Apparent Water Loss Performance Standard, as well as the real and apparent water losses included in the City’s most recent 2024 water loss audit.

The City will continue to improve dat a collection for assessing and reducing water losses while performing proactive measures to minimize real losses. City field personnel are trained to spot leaks and verify if water fr om fire hydrants is metered, permitted, or if the water is taken without authorization.

LAY DESCRIPTION – CHAPTER 5

SB X7-7 BASELINES, TARGETS, AND 2025 REPORTING

Chapter 5 (SB X7-7 Baselines, 2020 Targets, and 2025 Reporting) of the City’s 2025 Plan discusses and provides the following:

 The Water Conservation Act of 2009 (or SB X7-7) required the State of California to achieve a 20 percent reduction in urban water use by the year 2020.  SB X7-7 required urban water suppliers, in cluding the City, to develop a “2020 Water Use Target” to assist the State of California to achieve the 20 percent reduction. The 2020 Water Use Target represents the amount of water each person should use per day (i.e . gallons per capita per day or GPCD) by the year 2020.
 The City previously determined its 2020 Water Use Target during the preparation of its 2015 Plan by completing standardized tables (or the SB X7-7 Verification Form) to demonstrate compliance with t he Water Conservation Act of 2009. The City’s 2020 Water Use Target was 137 GPCD.
 The City’s per-capita water use dur ing Calendar Year 2020 was 104 GPCD. The City’s confirmed 2020 Water Use Target was 137 GPCD. The City’s per-capita water use during Calendar Year 2020 met the 2020 Water Use Target.

As indicated in Section 5.2.2, the City pr eviously met its 2020 Water Use Target as part of the 2020 Plan.

NEXUS TO STATE WATER BOARD URBAN WATER-USE
OBJECTIVES (NOT REQUIRED FOR UWMPs

SWRCB’s “Making Conservation A Way of Life Regulation” (under the California Code of Regulations, Title 23, Section 965 et seq) requires urban retail water suppliers to annually calculate and comply with an Urban Water Use Objective (UWUO); carry out commercial, industrial, and institutional (CII) performance measures; and provide progress reports.

The regulation is expected to reduce inefficient water use and protect water supplies from the effects of rising temperatures and drier conditions due to climate change.

The Urban Water Use Objective is the sum of standard-based water use budgets for efficient residential indoor us e, residential outdoor use, C II landscapes with dedicated irrigation meters (DIMs), and real water losses. Each budget is the product of the applicable standard and the water supplier’s uni que characteristics (e.g., population).

Water suppliers will be assessed for complian ce with their overall objective, not each standards-based budget.

The residential indoor water use standard is based on 55 GPCD (until December 31, 2024), 47 GPCD (from January 1, 2025 to January 1, 2030), and 42 GPCD (beginning January 1, 2030). The residential outdoor wa ter standard is based on a landscape

2025 Urban Water Management Plan

City of Glendale

efficiency factor (representing plant factors and irrigation efficiency) of 0.80 (until June 30, 2035), 0.63 (from July 1, 2035 to June 30, 2040), and 0.55 (beginning July 1, 2040). The standard for commercial, industrial, and inst itutional (CII) landscapes is based on a landscape efficiency factor of 0.80 (until June 30, 2035), 0.63 (from July 1, 2035 to June 30, 2040), and 0.45 (beginning July 1, 2040). Urban retail water suppliers are also required to comply with real water loss standards by January 1, 2028.

DWR has indicated that compliance with the Urban Water Use Objective requirements are under the authority of the SWRCB and that the requirements are not part of Urban Water Management Plan content requirements. However, the SWRCB uses the 2020 Water Use Targets as a back stop for the Urban Water Use Objective calculations. The Urban Water Use Objectives, together with excluded demands, are to be more efficient than the 2020 Water Use Targets.

SPECIFIC ANALYSIS APPLICABLE TO ALL WATER SUPPLY

SOURCES

The section below provides a discussion of the following information to the extent practical:

 The City’s existing and planned sour ces of water supply are identified;  Each source of supply is quantified in five-year increments through CY 2050;

2025 Urban Water Management Plan

City of Glendale

 The anticipated supply availability under normal, single dry, and five consecutive dry years, and any other water year co nditions included in the Drought Risk Assessment (see Chapter 7) are described;
 The management of each water supply in co rrelation with other identified supplies is described.
 Information pertinent to the reliability analysis, including climate change effects, is considered.

The City historically has relied on gr oundwater pumped from the San Fernando and Verdugo Basins and treated, imported surface water purchased from MWD. The following descriptions summarize the City’s sources of supply (detai led descriptions are provided in Section 6.2).

Existing and Planned Sources of Supply

Purchased Treated Imported Water

The City has historically purchased treated imported water from MW D, as described in Section 6.2.1. In addition, Section 6.2.1 provides a detailed discussion of the existing and planned supply of the treated imported water, including a description of the management and reliability of those treated imported water supplies. Table 6-8 summarizes the actual treated imported water supply for CY 2025. In addition, Table 6-9 summarizes the projected water supply, in five-year incr ements, through CY 2025 under varying water supply conditions.

Groundwater

The City has historically pumped groundw ater from the San Fernando and Verdugo Basins as described in Section 6.2.2. In addition, Section 6.2. 2 provides a detailed

2025 Urban Water Management Plan

City of Glendale

discussion of the existing and planned supply of the groundwater, including a description of the management and reliability of those groundwater supplies. Table 6-8 summarizes the actual groundwater supplies for CY 2025. In addition, Table 6-9 summarizes the projected water supply, in five-year incr ements, through CY 2050 under varying water supply conditions.

Surface Water

The City does not use surface water supplies to meet its water demands.

Storm Water

The City has historically received gr oundwater from the San Fernando and Verdugo Basins . Management and use of the stormwater runoff from the watershed is crucial to groundwater management. However, the City currently does not have its own program to beneficially use stormwater runoff as a direct source of supply.

A description of the City’s water system along with a map of its service area is included in Chapter 3. In addition, the agencies which manage the water supplies used by the City are identified in Section 6.2.1 (imported water), 6.2.2 (groundwater), 6.2.3 (surface water),

6.2.4 (stormwater), and 6.2.5 (recycled water).

OPTIONAL PLANNING TOOL

As discussed in Section 4.2.4, DWR has created an optional “Planning Tool Worksheet” for water suppliers to review and assess monthly water use trends. However, DWR has deemed the tool as optional and the City is not required by DWR to use the tool. Section

6.1 provides a tabulation of the City’s historical annual water uses for each water supply source. During the past 15 y ears, the City exper ienced a five consecutive year drought within its service area from CY 2011 to CY 2015. In addition, historical records indicate

2025 Urban Water Management Plan

City of Glendale

the City’s annual water demands typically have been even greater prior to CY 2011. The City has been able to provide sufficient water supplies to its customers, including during long-term droughts and years with historically high water demands. In addition, the City has been able to provide water service to meet maximum day water demands for these years, including during the summer months. A further discussion regarding the reliability of the City’s water supply sources is provided in Chapter 7.

SPECIAL CONSIDERATIONS

The City considered the issues described below when developing its planned sources of water supply.

6.1.2.1 CLIMATE CHANGE EFFECTS

Climate change has the possibility of impacting the availability of planned water supplies, particularly during a drought period. Section 4. 2.5.6 of this Plan provides a discussion regarding climate change effects on the City’s various sources of supply.

6.1.2.2 REGULATORY CONDITIONS AND PROJECT DEVELOPMENT

The City has considered the implications of emerging regulatory conditions and project development on the availabilit y of planned water supplies. Section 1.4 provides a discussion the reduced reliance on Delta water supplies.

6.1.2.3 OTHER LOCALLY APPLICABLE CRITERIA

There are no locally applicable criteria which applies to the City.

6.1.2.4 WHOLESALE AND RETAIL SUPPLIERS COORDINATION

Because the City relies on wholesale water supplies, the City has provided its 2025 Plan to MWD as discussed in Section 2.4.1.

City of Glendale

NARRATIVE SECTIONS FOR SUPPLI ER’S UWMP WATER SUPPLY

CHARACTERIZATION

PURCHASED OR IMPORTED WATER

METROPOLITAN WATER DISTRICT OF SOUTHERN CALIFORNIA

The City can purchase treated, imported water from MWD. MWD imports water from the Colorado River through the Colorado River Aqueduct, owned and operated by MWD, and the State Water Project, which utilizes th e California Aqueduc t for transmission to Southern California.

MWD uses a tiered rate structure for water sales to its member agencies, including the City. Any water purchases in excess of the Ti er 1 allocation may incur Tier 2 rates. The City can purchase treated, imported water directly from its G1 (4,488 gallons per minute, or gpm), G2 (3,141 gpm), and G3 (9,000 gpm) connections. The City’s purchases of treated, imported water from MWD over the past five years has been tabulated in Section

6.1. Over the past five years, the City has purchased 12,831 AFY to 14,816 AFY, with an average of 14,080 AFY from MWD. The City’s projected purchases of treated, imported water from MWD, over the next 25 years in fi ve-year increments, is provided in Table 6-

9. The City‘s treated imported water supplies from MWD may be impacted during a multi- year drought or other conditions which limi ts MWD from delivering sufficient water supplies to all of its member agencies, and consequently to the City. In anticipation of such a reduction in supplies, MWD devel oped a Water Supply Allocation Plan (WSAP) which is briefly described below. The WSAP provides a means of equitably providing

2025 Urban Water Management Plan

City of Glendale

reduced water supplies to each of MWD’s member agencies for up to 10 levels of reduction representing up to a 50 percent reduction.

During calendar year 2007, critically dr y conditions impacted MWD’s water supply sources. In addition, a ruling in the Federal Courts in August 2007 provided protective measures for the Delta Sm elt (and subsequently other aquatic species) in the Sacramento-San Joaquin River Delta resulting in restrictions on the availability of State Water Project water. As a result, MWD adopted a Water Supply Allocation Plan in February 2008 to allocate available water supplies to its member agencies. MWD revised the WSAP in December 2014.

The WSAP establishes ten different shorta ge levels and a corresponding Allocation to each member agency. Based on the shortage le vels established by MWD, the WSAP provides a separate reduced Allocation to a member agency for its 1) Municipal and Industrial (M&I) retail demand and 2) r eplenishment demand. The WSAP formula considers historical local water production, full service treated water deliveries, agricultural deliveries and water conservati on efforts when calculating each member agency’s Allocation.

In general, the WSAP process calculates tota l historical member agency demand. That historical demand is then compared to me mber agency projected local supply for a specific Allocation year. The balance requir ed from MWD, less an Allocation reduction factor, is the member agency’s “Water Supply Allocation” of imported water from MWD.

When a member agency reduces its local demand through conservation or other means, the Allocation of imported water will in crease. Depending on MWD’s available supply, MWD can establish a specific WSAP shortage level. The shortage level causes a regional reduction and calculates an allocation for each of its member agency. Additional information about MWD’s WSAP is provided in MWD’s Regional 2025 UWMP which is incorporated by reference. The following is a summary of MWD’s water shortage levels:

2025 Urban Water Management Plan

City of Glendale

Level 1 – Regional Percent Reduction of 5%
Level 2 – Regional Percent Reduction of 10%
Level 3 – Regional Percent Reduction of 15%
Level 4 – Regional Percent Reduction of 20%
Level 5 – Regional Percent Reduction of 25%
Level 6 – Regional Percent Reduction of 30%
Level 7 – Regional Percent Reduction of 35%
Level 8 – Regional Percent Reduction of 40%
Level 9 – Regional Percent Reduction of 45%
Level 10 – Regional Percent Reduction of 50%

In response to a fourth consecutive year of below average rainfa ll and critically dry conditions, MWD declared a WSAP Allocation Level 3 for fiscal year 2015-16, which represented a regional reduction of 15 percent. MWD rescinded the WSAP for fiscal year 2016-17 and has not reinstated the WSAP since that time.

Descriptions of the San Fernando and Verdugo Basins are provided below

SAN FERNANDO BASIN

San Fernando Basin - Sustainable Groundwater Management Act

The San Fernando Basin is located within the San Fernando Valley Basin (DWR Bulletin 118, Basin Number 4-012). Pursuant to the Sustainable Groundwater Management Act of 2014 (SGMA), the San Fernando Valley Basin was designated a very-low-priority basin in DWR’s 2019 SGMA Basin Prioritization report.

San Fernando Basin - Description

The San Fernando Basin consists of 112,000 acres and it is bounded on the east and northeast by the San Rafael Hills, Verdugo Mountains, and San G abriel Mountains; on the north by the San Gabriel Mountains and the eroded sout h limb of the little Tujunga

2025 Urban Water Management Plan

City of Glendale

Syncline which separates Sylmar Basin; on the northwest and west by the Santa Susan Mountains and Simi Hills; and on the south by the Santa Monica Mountains.

The San Fernando Basin is managed by the ULARA Watermaster which encompasses all the watershed and tributaries of the Los Angeles River and fo ur groundwater basins as shown in the figure below. The water storage of the basins are considered geologically separate and are replenished by deep percolation from rainfall, surface runoff and from a portion of the municipal-supply water that is delivered for use within these basins.

Groundwater flow in the San Fernando Basin ty pically trends from the edges toward the middle of the basin, converging beneath the Los Angeles River and into the Central Sub- basin of the Coastal Plain of Los Angeles Basin. In the northeastern part of the basin, groundwater moves from the La Crescent a area southward beneath the surface of Verdugo Canyon toward the Los Angeles rive r near Glendale, likewise the groundwater in the Sunland/Tujunga area flows west following the Tujunga Wash and eventually south to join groundwater flowing from the west half of the Basin following the course of the Los Angeles River near Glendale. The total stor age capacity of the San Fernando Basin is calculated at 3.67 million acre-feet (MAF).

San Fernando Basin - Adjudication

On September 30, 1955, the City of Los Angeles filed an action in Los Angeles Superior Court against the cities of San Fernando, Glendale and Burbank, t he Crescenta Valley Water District, and several other defendants (City of Los Angeles v. City of San Fernando, Los Angeles Superior Court Case No. 650079). The Superior Court appointed the State Water Rights Board as a referee in the acti on and directed it to in vestigate, find, and report upon certain physical facts of the ULARA. The State Water Rights Board adopted its Report of Referee and the resulting two-volume document is dated July 27, 1962.

The Cities of Burbank, Glendale, Los Angeles and San Fernando, t he Crescenta Valley Water District (CVWD), and several private parties with smaller water claims proceeded to a bench trial on March 1, 1966. Numerous other defendants were eliminated from the

2025 Urban Water Management Plan

City of Glendale

case before trial by dismissal, disclaimer, default, or stipulated judgment. On March 15, 1968, following more than 181 trial days, the judge entered a judgment.

The City of Los Angeles appealed that j udgment and, on May 12, 1975, the California Supreme Court, by unanimous opinion (1 4 Cal. 3d 199), reversed and remanded the case. The Supreme Court affirmed the City of Los Angeles’ Pueblo Water Rights to the surface waters of the Los Angeles River and all groundwater in the San Fernando Basin (SFB) derived from precipitation within ULARA (i nfiltration of direct rainfall plus surface water runoff). It held that the City of Los An geles’ Pueblo Water Rights did not extend to and/or include the groundwater in the Sylmar, Verdugo or Eagle Rock basins; however, it found that all surface water runoff and groundwater underflows fr om these adjoining groundwater basins were part of the City of Los Angeles’ Pueblo Water Rights.

The California Supreme Court held that t he City of Los Angeles had rights to all groundwater in the San Fernando Basin derived from water the City imported from outside ULARA that was eventually spread or deliv ered within the San Fernando Basin. The Supreme Court granted the cities of Bu rbank and Glendale similar rights also based on water they imported from out side ULARA and delivered within the San Fernando Basin.

Because the City of San Fernando was not a member of MWD until the end of 1971 and because it had never imported any water from outside ULARA prior to 1971, it was given no return flow rights based on a March 22, 1984- dated stipulation between the cities of Los Angeles and San Fernando.

The Superior Court entered the Final Ju dgment on January 26, 1979 and also issued Findings of Fact and Conclusions of Law t hat same day. This Judgment remains the governing document for ULARA. A copy of the Judgment is provided in Appendix F.

2025 Urban Water Management Plan

City of Glendale

Return Flow Credit

As part of the Judgment, the City of Glendale is entitled to a return flow credit of 20 percent of all delivered water (including recycl ed water) in the San Fernando Basin and its tributary hill and mountain area. The return fl ow credit is calculated by determining the amount of total water used in the City less 105 percent of total sales by Glendale to Verdugo Basin and its tributar y hills. This credit ranges from about 5,000 AFY to 5,400 AFY depending on actual water use. The J udgment does not provide for this right in Verdugo Basin.

There is a right to produce water beyond the City’s return flow credits subject to a payment obligation to the City of Los Angeles that is based primarily on the cost of MWD alternative supplies. This right to produce water in excess of the return flow credit and the accumulated credits are significant to t he operation of the Gl endale Water Treatment Plant (GWTP), which is part of a U.S. Environmental Protection Agency (EPA) Superfund clean-up project in Glendale. The project consis ts of a 5,000 gpm facility that delivers approximately 7,800 AFY to the City.

Physical Solution Water

The Judgment allows the City of Glendale to extract excess water chargeable against the rights of the City of Los Angeles upon paym ent of specified charges generally tied to MWD’s water rates. Glendale’s physical solution right is 5, 500 AFY Water Supplies in San Fernando Basin

Carry-over Extractions

In addition to extractions of stored water, th e City of Glendale may, in any water year, extract from San Fernando Basi n an amount not exceeding 10 percent of City’s last annual credit for import return wa ter, subject, however, to an obligation to replace such

2025 Urban Water Management Plan

City of Glendale

overextraction by reduced extractions durin g the next succeeding water year. Any such overextraction which is not so replaced shal l constitute physical solution water, which shall be deemed to have been extracted in said subsequent water year.

San Fernando Basin – Groundwater Treatment

In the 1970s, with the detection of high concentrations of volatile organic compounds (VOCs) in the San Fernando Basin, the Ci ty of Glendale lost the ability to use groundwater. In the 1980s and 1990s, under the Federal Superfund regulations, industries responsible for the contaminatio n were identified and a group of potentially responsible parties were requir ed to pay for the installation and operation of facilities to treat the groundwater. This treatment facility is referred to as the Glendale Operable Unit (GOU) and was completed in 1999. Secti on 2.5 of ULARA’s Policies and Procedures, dated July 1993, provides for the unlimited extraction of basin water for Superfund activities, subject to payment of specified charges similar to physical solution water. This right became a significant factor with the completion of the Glen dale Water Treatment Plant (GWTP) in 2000.

The GWTP was established to remove the VOCs in ground water supplies with the most prevalent being trichloroethylene (TCE) and te trachloroethylene (PCE). The GWTP also includes a treatment process to remove hexavalent chromium which was added in 2016.

The GOU has nine extraction wells located to concentrate and remove the contaminant plumes and raw water transmission mains to t he treatment facility. The nine wells are:

GN-1, 2, 3, 4, and GS-1, 2, 3, 4, 5. After treatment the water is delivered to the City’s Grandview facility for blending and conversion to a chloramine disinfectant residual. The GWTP operates at a rate of up to 5,250 gpm and delivers all of San Fernando Basin water used by the City.

San Fernando Basin - Historical and Projected Basin Production

The City currently produces groundwater fr om the San Fernando Basin. The City’s production over the past five years has been tabulated in Section 6.1. Over the past five years, the City has produced 6,725 AFY to 7,698 AFY, with an average of 7,146 AFY from the San Fernando Basin. The City’s projected production from the San Fernando Basin, over the next 25 years in five-year increments, is provided in Table 6-9.

VERDUGO BASIN

Verdugo Basin - Sustainable Groundwater Management Act

Similar to the San Fernando Basin, the Verdugo Basin is located within the San Fernando Valley Basin (DWR Bulletin 118, Basin Num ber 4-012). Pursuant to the Sustainable Groundwater Management Act of 2014 (SGMA), the San Fernando Valley Basin was designated a very-low-priority basin in DWR’s 2019 SGMA Basin Prioritization report.

Verdugo Basin - Description

The Verdugo Basin consists of 4,400 acre s and is bounded on the north by the San Gabriel Mountains; on the northwest by a groundwater divide, which separates it from the San Fernando Basin; on the east by a groundwater divide separating it from the Monk Hill Subarea of the Raymond Basin; on the southeas t by the San Rafael Hills; and on the south and southwest by the Verdugo Mountains. All the surface water channels feed into the Verdugo Wash, which is located along the west side of the basin. The groundwater storage capacity of the Verdugo Basin is approximately 160,000 AF.

The Verdugo Basin is managed by the ULARA Watermaster which encompasses all the watershed and tributaries of the Los Angeles River and four groundwater basins as shown above in Figure 3. The water storage of the basins are considered geologically separate

2025 Urban Water Management Plan

City of Glendale

and are replenished by deep percol ation from rainfall, surfac e runoff and from a portion of the municipal-supply water that is delivered for use within these basins.

Verdugo Basin - Adjudication

The adjudication of the Verdugo Basin’s is described above, as it was included in the San Fernando Basin Judgment (along with Sy lmar Basin and Eagl e Rock Basin). The Judgment gave Glendale the right to extract 3,856 AFY from the Verdugo Basin. CVWD also has water rights to extract 3,294 AFY and is the only other entity allowed to extract water from the Verdugo Basin.

Glendale has four active wells in the Verdugo Basin (including the Gl orietta 3, Glorietta 4, Glorietta 6, and Foothill wells). Due to the Verdugo’s Basin physical characteristics and declining precipitation in the area, groundw ater levels have been declining for decades.

As a result, the City has never pumped its full water right from Verdugo Basin. In addition, the City’s wells have recently been taken offline due to low production flowrates due to declining groundwater levels. To increase it s groundwater production capacity, the City constructed the Rockhaven Well. However, a fter construction, nitrate levels were discovered in the well which would require treatment. As a result, the City entered into a mutually beneficial lease agreement with CVWD wherein lease payments offset the City’s capital costs of construction and pay for CVWD’s use of the City’s water rights when the well is pumped. Since 2016, this arrangement has allowed the City to utilize its available water rights. CVWD pumps the water from the Rockhaven Well to an existing CVWD nitrate removal treatment plant in the CVWD system.

Verdugo Basin - Historical and Projected Basin Production

The City’s production from the Verdugo Basin over the past five years has been tabulated in Section 6.1. Over the pas t five years, the City has produced 0 AFY to 836 AFY, with an average of 457 AFY from th e Verdugo Basin. The City’s projected production from

(f) A description of actions, including financial in centives, which may be taken to encourage the use of recycled water, and the projected result s of these actions in terms of acre-feet of recycled water used per year.

(g) A plan for optimizing the use of recycled water in the supplier’s service area, including actions to facilitate the installation of dual distributi on systems, to promote recirculating uses, to facilitate the increased use of treated wastewater that meet s recycled water standards, and to overcome any obstacles to achieving that increased use.

Discussion of wastewater collection, treatment, and recycled water use is included in this chapter. Municipal recycled water is munici pal wastewater that has been treated at a municipal wastewater facility in a manner specified by t he SWRCB-DDW to a specified quality to enable it to be used again for a beneficial purpose. Municipal wastewater must meet two requirements; it must be reused beneficially pursuant to Title 22 of the California Code of Regulations and it must be reused in accordance with a Regional Water Quality Control Board permit. Title 22 of the Califo rnia Code of Regulations defines beneficial reuse of recycled water as “...the use of recycled water that has been transported from the point of treatment or pr oduction to the point of use wi thout an intervening discharge to water of the State....”

The City is co-owner of the Los Angeles – Glendale Water Reclamat ion Plant with the City of Los Angeles. The LAGWRP is part of an integrated network of facilities, known as the North Outfall Sewer (NOS), which includes four wastewater treatment plants (WRPs).

The upstream treatment plants (Tillman WR P, LAGWRP, and Burbank WRP) discharge solids to the Hyperion WRP. This system also allows biosolids, solids, and excess flows to be diverted from the upstream plants to the Hyperion WRP for treatment and disposal.

LAGWRP produces disinfected “tertiary treat ed” wastewater effl uent that meets or exceeds the water quality standards, codified in the California Code of Regulations, for recycled water for non-potable uses permitted by the State of California, such as landscape irrigation and industrial processing.

2025 Urban Water Management Plan

CWC 10633.

(a) A description of the wastewater collection and treatment systems in the supplier’s service area, including a quantification of the amount of wa stewater collected and treated and the methods of wastewater disposal.

Wastewater generated by the City is treated at the LAGWRP. The LAGWRP began operations in 1976 and has a treatment capacity of 20 million gallons per day (mgd), or 22,400 AFY. The LAGWRP provides disinfected tertiary treated effluent. All wastewater treated at the LAGWRP meets recycled water st andards. The City has a right of up to

2025 Urban Water Management Plan

City of Glendale

11,200 AFY of the resulting hi ghly treated wastewater effluent. The sludge generated at LAGWRP is sent back to the sewer, wh ich conveys the sludge downstream to the Hyperion Treatment Plant. Excess tertiary water is discharged to the Los Angeles River.

It is estimated approximately 69 gallons per person per day of wast ewater is generated within Los Angeles County. Based on a 20 25 population of 189,562 within the City, the estimated amount of wastewater collected by the City is approx imately 13.1 million gallons per day (about 14,700 AFY), as shown in Table 6-2.

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.

(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 reus e, and other appropriate uses, and a determination with regard to the technical and econom ic feasibility of serving those uses.

(e) The projected use of recycled water within the supplier’s service area at the end of 5, 10, 15, and 20 years, and a description of the actual us e of recycled water in comparison to uses previously projected pursuant to this subdivision.

This section discusses the potential, curren t, and projected beneficial use of recycled water within the City. Beneficial use is def ined by Title 22 of the California Code of Regulations as “the use of recycled water that has been transported from the point of treatment or production to the point of use without an intervening discharge to the waters of the State.”

The City’s recycled water system currently serves many Glendale Unified School District facilities for outdoor irrigation, irrigat ion of Glendale and Cal-Trans medians and embankments, many Glendale Parks, and service to dual plumbed buildings at Glendale City College, several office buildings as well as several facilities at the Disney campus in Glendale, and the cooling towers at the City’s Grayson Power Plant.

Table 6-4 describes the supply currently being used and the supply available for use in a recycled water project. Table 6-5 compares the projected use for 2025 versus actual use of recycled water in 2025.

The City’s planned recycled water projects in clude connection to the City of Pasadena and completion of the recycled water system expansions. The planned expansions include service to Hoover High School, Toll Middle School, and Keppel Elementary School through a main extension. The “Glendale T” project will loop the recycled system through the major commercial area of Glendale providing the ability to connect to existing dual plumbed office buildings. The Chevy Oaks, Camino San Rafael Homes, and the Chevy Chase Golf Course expansions, via a pump station, tank, and main extensions will offset large irrigation customers in the Chevy Chase Canyon area.

6.2.5.5 ACTIONS TO ENCOURAGE AND OPTIMIZE FUTURE

RECYCLED WATER USE

CWC 10633.

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, wastew ater, groundwater, and planning agencies that operate within the supplier’s service area, and shall include all of the following:

(g) A plan for optimizing the use of recycled water in the supplier’s service area, including actions to facilitate the installation of dual distributi on systems, to promote recirculating uses, to facilitate the increased use of treated wastewater that meet s recycled water standards, and to overcome any obstacles to achieving that increased use.

The City works to encourage and optimize futu re recycled water use within its service area. Through marketing efforts, the City’s recycled water customers have expanded from tradition irrigation users such as golf courses and parks to unconventional and industrial users. Additionally, the City provides in centives by setting recycled water rates below potable water rates to encourage recycled water use.

DESALINATED WATER OPPORTUNITIES

CWC 10631.

(g) Describe the opportunities for development of desalinated water, including, but not limited to, ocean water, brackish water, and groundwater, as a long-term supply.

The City is currently not cons idering the development of a desalinated water project.

However, there may be opportunities for use of desalinated ocean water as a potential water supply source in the future, if needed, through coordination with other agencies that have ocean desalination programs.

WATER EXCHANGES AND TRANSFERS

CWC 10631.

(c) Describe the opportunities for exchanges or tr ansfers of water on a short-term or long-term basis.

6.2.7.1 EXCHANGES

Pursuant to DWR’s 2025 Final Guidebook, “ Water exchanges are typically water delivered by one water user to another water user, with the receiving water user providing water in return at a specified time or w hen the conditions of t he parties’ agreement are met. Water exchanges can be strictly a retu rn of water on a basis agreed upon by the participants or it can include payment and the return of water.”

The City does not have any current or planned water exchanges.

2025 Urban Water Management Plan

City of Glendale

6.2.7.2 TRANSFERS

Pursuant to DWR’s 2025 Final Guidebook, “The Water Code defines a water transfer as a temporary or long-term change in the point of diversion, place of use, or purpose of use due to a transfer, sale, lease, or exchange of water or water rights.”

The City does not have any current or planned water transfers.

6.2.7.3 EMERGENCY INTERTIES

The City has emergency interties (or interc onnections) with other water agencies that serve as short-term emergency exchange opportunities. Emergency interconnections are distribution system interconnections between water agencies for use during critical situations where one system or the other is temporarily unable to provide sufficient potable water to meet its water demands and/or fire pr otection needs. An emergency interconnection will allow a water system to continue serving water during critical situations such as local water supply shor tages as a result of earthquakes, fires, prolonged power outages, and droughts.

The City has the ability to receive water fr om interconnections with the City of Burbank and CVWD for short-term emergency water service.

SUPPLY FROM STORAGE

Section 6.2.8 is not applicable. The City does not remove water from either surface storage or underground storage for use (including surface water placed into storage in a given year and retrieved in the following year).

The City does not rely on any additional water supply sources.

FUTURE WATER PROJECTS

CWC 10631.

(f) Include a description of all water supply projects and water supply programs that may be undertaken by the urban water supplier to meet the total projected water use, as established pursuant to subdivision (a) of Section 10635. The urban water supplier shall include a detailed description of expected future projects and programs that the urban water supplier may implement to increase the amount of the water supply available to the urban water supplier in normal and single-dry water years and for a perio d of drought lasting five consecutive water years. The description shall identify specific projects and include a description of the increase in water supply that is expected to be available from each project. The description shall include an estimate with regard to the implementation timeline for each project or program.

The City will supply the majority of its potab le water via its imported water from MWD.

The remainder of its supply will be provided by groundwater from the San Fernando and Verdugo Basins. The City’s Water Master Plan also identified future improvement projects, including replacing gr oundwater wells with the objective to continue improving system reliability, water quality, and reduce the City’s dependence on imported water.

ENERGY USE

CWC 10631.2.

(a) In addition to the requirements of Secti on 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 us ed 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.

2025 Urban Water Management Plan

City of Glendale

(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 fo r 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.

“Energy intensity” is defined as the quantity of energy consumed, measured in kilowatt hours (kWh), divided by the volume of wa ter, measured in acre-feet for a water management process over a one-year period. The information used to calculate the estimated energy intensity associated with the City’s water system is provided below. The energy intensity information is based on readily obtainable energy and water use data for the following water management processes: 1) extraction or diversion of water supplies; 2) placement into storage; 3) conveyance to distribution; 4) tr eatment; and 5) water system distribution.

The City has tabulated its energy intensity using readily obtainable energy consumption data obtained from monthly electricity bills from Glendale Water and Power for the whole water system and the corresponding water use data obtained from available water meter readings. The City has reported the energy intensity associated with the water management processes which occur within its operational control. Because the City does not track individual energy usage for eac h water management process identified above, the City has estimated the energy intensity using the a “total utility approach” (i.e. sum of all water management processes). The to tal energy consumed was approximately 12,132,121 kWh during CY 20 25. Although the total ener gy consumption reported includes electricity usage for general admin istration (e.g. at the City’s headquarters) which is not associated with any wa ter management processes, the general

2025 Urban Water Management Plan

City of Glendale

administration energy usage is considered negligible compared to overall water system use and has not been netted out.

The total volume of water entering the potable water system wa s approximately 21,717 AF during CY 2025 and is consistent with the total volume of water provided in Table 4-1 less recycled water supplies.

The total energy intensity associated with the City’s water management processes is estimated at 1,714 kWh per million gallons. The energy intensity data and calculations based on the “total utility approach” are provided in Table O-1B below.

The City’s water management processe s do not include “consequential hydropower generation” where the energy generation is a direct consequence of water delivery (i.e. all water passing through the energy generation devices is delivered to users). The City’s water management processes do not include “non-consequential hydropower generation” where the energy generation is not a direct consequence of water delivery (i.e. energy could be generated even if no water was being delivered to water users). In addition, the City’s water management processes do not include any substantial “self-generated energy sources” including solar, wind, geother mal, biomass, co-generation, and diesel generator sources.

TABLE 6-8: WATE R SUPPLIES—ACTUAL

As discussed in Section 6.2, the City’s water supply sources consist of treated imported water purchased from MWD (see Section 6.2.1) and groundwater from the San Fernando and Verdugo Basins (see Section 6.2.2). T he actual quantities of the water supply sources available to the City during CY 2020 are summarized in Table 6-8. The reliable quantities of projected water supply sources available to the City in five-year increments through CY 2050 during normal or average years are summarized in Table 6-9. The

2025 Urban Water Management Plan

City of Glendale

reliability of these sources of supply are addressed in Section 7.2.3, including during normal years, single dry years, and five consecutive year droughts.

The order of use of the City’s projected reliable water supplies from CY 2020 through CY 2050 in five-year increments is based on historical practices, water supply availability, and the cost of water. It is anticipated the City will initially use groundwater produced from the San Fernando and Verdugo Basins. At the sa me time, the City will continue to use recycled water for non-potable demands. The City will also use treated imported water.

It is important to note t hat the San Fernando and Verdugo Basins are adjudicated (as discussed in Section 6.2.2). In the event tr eated imported water may be limited, the City has the flexibility to increase groundwater produc tion (in excess of its return flow credit) from the San Fernando Basin.

The City’s projected quantities of treated imported water supplies are based on historical long-term averages and available supplies during previous dry year conditions. The City’s projected quantities of groundwater supplies from the San Fernando Basin are based on meeting the remainder of the City’s total water demands. As noted above, in the event treated imported water may be limited, the City has the flexibility to increase groundwater production from the San Fernando Basin. Consequently, it is anticipated the City will have sufficient water supplies available to meet projected demands.

CHAPTER 7

WATER SERVICE RELIABILITY AND DROUGHT RISK ASSESSMENT

LAY DESCRIPTION – CHAPTER 7

WATER SERVICE RELIABILITY AND DROUGHT RISK ASSESSMENT

Chapter 7 (Water Service Re liability and Drought Risk Asse ssment) of the City’s 2025 Plan discusses and provides the following:

 CY 2020 represents an “average” or “normal” water year for the City in which the total amount of rainfall was similar to the historical average rainfall.  A “single dry” year for the City was represented in CY 2017, in which the total amount of rainfall was below the historical average rainfall.  A “five consecutive year drought” period fo r the City is represented from CY 2011 to CY 2015, where the total amount of rainfall during each of these years was less than the historical average rainfall.
 The City’s current and projected water supplies available dur ing normal years in five-year increments over the next 25 y ears are provided (through Calendar Year 2050) as shown on Table 7-2.
 The City’s current and projected water supplies available during single dry years in five-year increments over the next 25 years are provided (through Calendar Year 2050) as shown on Table 7-3.
 The City’s current and projected water suppl ies available during each year of a five consecutive year drought in five-year increments over the next 25 years are provided (through Calendar Year 2050) as shown on Table 7-4.  The reliability of the City’s water supply sources, including a review of water supply constraints, is provided. A single dry year or a five consecutive year drought period

2025 Urban Water Management Plan

City of Glendale

will not compromise the City’s ability to provide a reliable supply of water to its customers.
 A Drought Risk Assessment (or DRA) is provided which includes an assessment of the City’s water supply reliability over a five consecutive year drought period.

The City’s DRA assumes a five consecutive year drought from CY 2026 through CY 2030 and includes a revi ew of water supplies, water uses, and water supply reliability for each water supply source duri ng this period. The City has the ability to enact varying water shortage levels (see Chapter 8) to help educate its customers and provide an econom ic incentive for the reta il customers to reduce their water consumption.

This section of the City’s Plan describes the City’s ability to meet retail customer water demands by analyzing a variety of factors whic h affect the City’s water supply. This section assesses the City’s water service reliability during average years, single dry years, and during a five consecutive year dr ought period to meet the water needs of its customers. This section also includes the discussion of a Drought Risk Assessment which provides a mechanism for the City to evaluate the risk to its water supply under a drought lasting for the next five consecutive years.

CONSTRAINTS ON WATER SOURCES CONSIDERATION

CWC 10631.

(b)(1) 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.

Water Code Section 10634

2025 Urban Water Management Plan

City of Glendale

The plan shall include information, to the extent practicable, relating to the quality of existing sources of water available to the supplier over the same five-year increments as described in subdivision (a) of Section 10631, and the manner in which water quality affects water management strategies and supply reliability.

Water Code Section 10635

(b)(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.

Water Code Section 10635

(b)(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.

SERVICE RELIABILTY - CONS TRAINTS ON WATER SOURCES

The City’s sources of supplies consist of groundwater pumped from the San Fernando and Verdugo Basins and treated, imported surface water purchased from MWD, as described in Section 6.2. Although all of these supplies are managed, the following constraints may occur which the City has considered in this reliability analysis.

San Fernando Basin

The City produces groundwater from th e San Fernando Basin. The groundwater historically had been impacted by contamination. However, the City has developed and implemented appropriate treatment which have been approved by SWRCB-DDW. These groundwater supplies are considered reliab le both from a water quality and quantity standpoint.

2025 Urban Water Management Plan

City of Glendale

Imported Water

The City also receives treated surface water from MWD. Water quality from MWD relating to supply reliability is addressed separ ately in MWD’s 2025 Regional Urban Water Management Plan.

WATER SERVICE RELIABILITY ASSESSMENT

CWC 10635.

(a) 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 cust omers 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 suppl ier 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 informat ion 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.

Information regarding the reliability of the City’s water supplies is based on the historical precipitation data in t he San Fernando and Verdugo Basins. Historical annual precipitation in theses areas is discussed in Section 3.3. Furthermore, Section 4.2.5.6 of this Plan notes that potential future climat e change impacts may result in an increase in the average annual precipitation within the City ’s service area, thus indicating use of historical data is a reasonable and conserva tive approach. As indicated in Section 3.3, the historical average rainfall in the vicinity of the City’s service area is 16.5 inches. CY 2020 represents an average or normal water year for the City in which the total amount of rainfall was similar to the historical average rainfall. A single dry year for the City was represented in CY 2017, in which the total amount of rainfall was below the historical average rainfall. A five consecutive year dr ought period for the City is represented from CY 2011 to CY 2015, where the total amount of rainfall during each of these years was

2025 Urban Water Management Plan

City of Glendale

less than the historical average rainfall. T able 7-1 summarizes these “base years” for average, single dry, and five consecutive ye ar drought and provides the total amount of water supplies available to the City duri ng those base years. The following discussion assesses the water service reliability of the City’s water supply sources.

Water Service Reliability - Imported Water

The City’s treated imported water supplies from MWD may be impacted during a multi- year drought or other conditions which limi ts MWD from delivering sufficient water supplies to all of its member agencies, and consequently to the City. In anticipation of such a reduction in supplies, MWD developed a WSAP which is briefly described below.

The WSAP provides a means of equitably pr oviding reduced water supplies to each of MWD’s member agencies for up to 10 levels of reduction representing up to a 50 percent reduction.

During calendar year 2007, critically dr y conditions impacted MWD’s water supply sources. In addition, a ruling in the Federal Courts in August 2007 provided protective measures for the Delta Sm elt (and subsequently other aquatic species) in the Sacramento-San Joaquin River Delta resulting in restrictions on the availability of State Water Project water. As a result, MWD adopted a WSAP in February 2008 to allocate available water supplies to its member agenc ies. MWD revised the WSAP in December 2014.

The WSAP establishes ten different shorta ge levels and a corresponding Allocation to each member agency. Based on the shortage le vels established by MWD, the WSAP provides a separate reduced Allocation to a member agency for its 1) M&I retail demand and 2) replenishment demand. The WSAP form ula considers historical local water production, full service treated water deli veries, agricultural deliveries and water conservation efforts when calculating each member agency’s Allocation.

2025 Urban Water Management Plan

City of Glendale

In general, the WSAP process calculates tota l historical member agency demand. That historical demand is then compared to me mber agency projected local supply for a specific Allocation year. The balance requir ed from MWD, less an Allocation reduction factor, is the member agency’s “Water Supply Allocation” of imported water from MWD.

When a member agency reduces its local demand through conservation or other means, the Allocation of imported water will in crease. Depending on MWD’s available supply, MWD can establish a specific WSAP shortage level. The shortage level causes a regional reduction and calculates an allocation for each of its member agency. Additional information about MWD’s WSAP is provided in MWD’s Regional 2025 UWMP which is incorporated by reference. The following is a summary of MWD’s water shortage levels:

Level 1 – Regional Percent Reduction of 5%
Level 2 – Regional Percent Reduction of 10%
Level 3 – Regional Percent Reduction of 15%
Level 4 – Regional Percent Reduction of 20%
Level 5 – Regional Percent Reduction of 25%
Level 6 – Regional Percent Reduction of 30%
Level 7 – Regional Percent Reduction of 35%
Level 8 – Regional Percent Reduction of 40%
Level 9 – Regional Percent Reduction of 45%
Level 10 – Regional Percent Reduction of 50%

In response to a fourth consecutive year of below average rainfa ll and critically dry conditions, MWD declared a WSAP Allocation Level 3 for fiscal year 2015-16, which represented a regional reduction of 15 percent. MWD rescinded the WSAP for fiscal year 2016-17 and has not reinstated the WSAP since that time.

2025 Urban Water Management Plan

City of Glendale

Water Service Reliability - Groundwater

The San Fernado Basin groundwater supplies are managed by the ULARA Watermaster, as discussed in Section 6.2.2. During a nor mal year (CY 2020), the City met about 23 percent of its total demands with supplies from the San Fernado Basin. During a single dry year (CY 2017), the City met about 23 percent of its total demands with supplies from the San Fernado Basin. During a five c onsecutive year drought (CY 2011 to CY2015), the City met between 17 and 22 percent of its total demands with supplies from the San Fernado Basin.

Water Service Reliability Summary

Table 7-1 shows the water supplies during t he base years (for average year, single dry year and a five consecutive year drought). As a result of the City’s diverse water supply portfolio, water supplies may be re-apportioned during a five consecutive year drought to meet the City’s water demands.

WSRA YEAR-TYPE CHARACTERIZATION

7.2.1.1 TYPES OF YEARS

The City’s base years for an average year, a single dry year, and a five consecutive year drought are discussed in Section 7.2 and are su mmarized in Table 7-1. As indicated in Chapter 6, the City’s water supplies source s have been sufficient in meeting the City’s historical water demands during an average year, a single dry year, and a five consecutive year drought. An average year was based on a historical year during the past 15 years with a total precipitation similar to the historical average precipitation in the vicinity of the City’s service area. Because a single dry year or a five consecutive year drought period will not compromise the City’s ability to provide a reliable supply of water to its customers,

2025 Urban Water Management Plan

City of Glendale

a single dry year in this Plan was selected based one of the driest years during the past 15 years. The five consecutive year drou ght period was based on a period of five consecutive dry years during the past 15 years.

As indicated in Section 3.3, the historical average rainfall in the vicinity of the City’s service area is 16.5 inches. CY 2020 represents an aver age or normal water year for the City in which the total amount of rainfall was similar to the historical average rainfall. A single dry year for the City was represented in CY 2017, in which the total amount of rainfall was less than the historical average rainfall. A five consecutive year drought period for the City is represented from CY 2011 to CY 2015, where the total amount of rainfall during each of these years was less than the historical average rainfall. Table 7-1 summarizes these “base years” for an average year, a single dry year and a five consecutive year drought period and provides the total amount of water supplies available to the City during those base years.

7.2.1.2 SOURCES FOR WATER DATA

The monthly historical av erage temperatures (incl uding minimum and maximum), monthly historical average rainfall, and monthly ETo in the vicinity of the City’s service area are discussed in Section 3. 3 Historical climate inform ation was obtained from the WRCC, DPW, and from DWR’s CIMIS.

WSRA SUPPLY AND DEMAND COMPARISON

CWC 10635.

(a) 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 cust omers 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 suppl ier 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 reliabilit y

2025 Urban Water Management Plan

City of Glendale

assessment shall be based upon the informat ion 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.

The City obtains its water supply from imported water purchased from MWD and from groundwater wells located in the San Fernando Basin and Verdugo Basin. As discussed in Section 7.3 and shown in Table 7-2, Table 7-3, and Table 7-4, each of the City’s water supply sources share the same base years. As previously discussed in Section 7.2.1, a single dry year or a five consecutive year drought period will not compromise the City’s ability to provide a reliable supply of water to its customers.

The City’s projected normal year water demands over the next 25 years are discussed in Section 4.2.6. The ratio of total water supplies (including potable and recycled water supplies) available to the City during a historical average year in CY 2020 (or 25,547 AF) and during a historical single dry year in CY 2017 (or 25,158 AF) was used to estimate the City’s projected water demands during si ngle dry years. The ratio of total water supplies available to the City during a historical average year in CY 2020 (or 25,547 AF) and a historical a five consecutive year drought period from CY 2011 to CY 2015 (or 27,623 AF, 28,789 AF, 29,520 AF, 28,269 AF, and 24,421 AF, respectively) was used to estimate the City’s projected water deman ds during a five consecutive year drought period. The City’s projected dry year water supplies over the next 25 years were based on the minimum supplies needed by the City to meet projected single-dry year demands.

Table 7-2, Table 7-3, and Table 7-4 summari ze the City’s projected water demands and supplies over the next 25 years in five-year increments, including during normal years, single dry years, and a five consecutive year drought periods. These tables indicate the City can meet water demands during normal years, single dry years, and a five consecutive year drought periods over the next 25 years.

WSRA DESCRIPTION OF MANAGEMENT TOOLS AND

OPTIONS

CWC 10620.

(f) An urban water supplier shall describe in the plan water management tools and options used by that entity that will maximi ze resources and minimize the need to import water from other regions.

2025 Urban Water Management Plan

City of Glendale

As noted in Section 6.2.2, the San Fernando Basin is managed by the ULARA Watermaster. During the period of management under the Judgment, significant drought events have occurred. In each drought cycle the San Fernando Basin has been managed to maintain water levels. Therefore, based on historical and on-going management practices, the City will be able to rely on the San Fernando Ba sin for adequate supply over the next 25 years under single dry years and a five consecutive year drought periods.

Section 6.2.2 provides a description of the management of groundwater resources in the San Fernando Basin , as well as inform ation on basin management. Chapter 6 also demonstrates the management structure of the San Fernando Basin provides a reliable source of groundwater supply for the City during a normal year, a single-dry year and a five consecutive year drought. Historical data indicates the San Fernando Basin has been well managed for the full period of the adjudication, resulting in a stable and reliable water supply. Basin management changes are discussed in Section 6.2.2 and include increased direct use of recycled water (see Section 6. 2.5). Therefore, the groundwater supplies in the San Fernando Basin are deemed reliable.

DROUGHT RISK ASSESSMENT

CWC 10612.

“Drought Risk Assessment” means a method that examines water shortage risks based on the driest five-year historic sequence for the agency’s water supply, as described in subdivision (b) of Section 10635.

CWC 10635.

(b) 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

2025 Urban Water Management Plan

City of Glendale

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 consecutiv e 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 t hat 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.

The City’s sources of supplies consist of groundwater from the San Fernando and Verdugo Basins (which are managed by t he ULARA Watermaster) and treated import water purchased and managed by the Metropolitan Water District of Southern California.

The following discussion provides a DRA wh ich assesses the City’s water supply reliability over a five consecutive year drought period. The City’s DRA incorporates a five consecutive year drought from CY 2026 through CY 2030 and includes a review of water supplies, water uses, and water supply reliability.

DRA, DATA, METHODS, AND BASIS FOR WATER SHORTAGE

CONDITIONS

The City’s DRA was prepared using historical production data from the City’s water supply sources. The following assumptions were considered during the preparation of the City’s DRA for each year of the five consecutive year drought:

 The five consecutive year drought peri od associated with the 2025 Plan is based on five consecutive dry years from CY 2026 through CY 2030.

2025 Urban Water Management Plan

City of Glendale

 The projected water supplies available dur ing each year of this five consecutive year drought are assumed to be identical to the water supplies produced during each year between CY 2011 and CY 2015 (which represents the most recent and historical five consecutive year drought).
 The projected demands during this five consecutive year drought are based on water demands from CY 2020 (a normal y ear) which were adjusted based on projected population over the next five years along with the ratio of the normal year demands to actual demands over each year of the most recent and historical five consecutive year drought period (from CY 2011 and CY 2015).  The projected demands were compared to the projected supplies to identify potential water supply deficits which may require implementation of the Water Shortage Contingency Plan (discussed further in Chapter 8).

The following methodologies were considered during the preparation of the City’s DRA during for each year of the five consecutive year drought:

 Drought Year 1: The region had experi enced an average to above average year of precipitation in the prior year. Wa ter use in the prior year had been below average due to a reduce need for outdoor wa ter use, the groundwater basin had been replenished from above average local stormwater runoff, and imported water supplies were not restricted.
 Drought Year 2: The r egion experienced a second year of below average precipitation and runoff. Retail customers increase water use for outdoor irrigation to compensate for lack of precipitation. Groundwater and imported water supplies have not been impacted. Local surface water supplies have not been impacted.  Drought Year 3: The region experienced a th ird year of below average precipitation and runoff. Retail customers increase water use for outdoor irrigation to compensate for lack of pr ecipitation. Groundwater and imported water supplies

City of Glendale

have not been impacted. However, t here is an increased demand on both groundwater and treated imported water.
 Drought Year 4: The region experienced a fourth year of below average precipitation and runoff. Groundwater supplies have not been impacted. However, there is an increased demand on groundwater.
 Drought Year 5: Fifth year of below average precipitation and runoff. Groundwater supplies have not been impacted. Howeve r, there is an increased demand on groundwater.

DRA INDIVIDUAL WATER SOURCE RELIABILITY

The City’s DRA incorporates a five consecutive year drought based on five consecutive dry years commencing in CY 2025. The quantity of water supplies available for each year during this five consecutive year drought period included in the City’s DRA is assumed to be the same as the quantity of water supplies produced by the City during the most recent and historical five consecutive year drough t which occurred from CY 2011 through CY 2015. Production data for those years have been t abulated in Section 6.1. The following describes the anticipated reliability of each wa ter source for each year of the five consecutive year drought based on recent experience.

Groundwater

The City produces groundwater supplies from the San Fernando Basin which is actively managed by the ULARA Watermaste r, as described in Sect ion 6.2.2. The quantity of groundwater used (and reliably available) dur ing the most recent and historical five consecutive year drought period have been tabul ated in Section 6.1. During this period, the City was able to increase its producti on of its groundwater supplies from an adjudicated and managed groundw ater basin. The City also had the ability to systematically implement aspects of its Water Shortage Contingency Plan (see Chapter

2025 Urban Water Management Plan

City of Glendale

8). As a result of these coll ective actions (and experience during prior consecutive five- year droughts), the City does not anticipat e a water supply shortage from the San Fernando Basin .

Imported Water

The City obtains imported water from MW D. Section 6.2.1 describes the planning conducted by MWD regarding treated imported water supplies available to the City. The reliability of MWD’s supplies is also discussed in its 2025 Regional UWMP and is incorporated by reference. The City purchases treated imported water which is delivered directly within its distribution system. The City’s purchases of treated, imported water over the past 15 years have been tabulated in Sect ion 6.1. In the event of a drought which limits imported water supplies, the City will rely on its groundwater production.

The imported water purchases by the City dur ing the most recent and historical five consecutive year drought period have been tabulated in Section 6.1. Because the City’s DRA assumes the most recent and historical five consecutive year drought scenario will be repeated over the next five years, it is assumed the quantity of treated imported water supplies purchased during the mo st recent and historical fi ve consecutive year drought scenario will be available. Furthermore, this constitutes the mini mum amount of treated imported water which may be available in a fu ture five consecutive year drought absent MWD’s programs which it has since implemented.

Recycled Water

The City has a recycled water distribution syst em which it has developed over the years to reduce demands on its potable water suppl ies as described in Section 6.2.5. The availability of recycled water supplies is not adversely impacted by drought conditions and are locally available.

2025 Urban Water Management Plan

City of Glendale

The quantity of recycled water used during the most recent and historical five consecutive year drought period have been tabulated in Se ction 6.1. The quantity of recycled water available during each year of the most recent and historical five consecutive year drought is expected to be available during a future five consecutive year drought.

Summary

The City’s water system has experienced a pr ior five consecutive year drought with no limitation to its collective water supplies. Ho wever, the cost of those water supplies may have increased based on the mix of supplies which are used. Consequently, the City has the ability to enact varying Demand Management Measures (see Chapter 9) to help educate its customers and prov ide an economic incentive fo r the retail customers to reduce their water consumption.

DRA TOTAL WATER SUPPLY AND USE COMPARISON

Gross water use for the projected five consec utive year drought is shown on Table 7-5.

Section 7.3.2 describes the water source reliability for each source of supply the City will rely on during a five consecutive year drought. The annual quantities are summed and are also provided on Table 7-5. For the purpos es of the City’s DRA, as a worst-case scenario, the City has considered no water supply augmentation (as indicated in Table 7- 5) from its groundwater supplies. When necessary, the City can implement various water shortage levels of its Water Shortage Contingency Plan (as discussed in Chapter 8) in order to reduce its water demands. As shown in Table 7-5, assuming no additional water supply benefits will be available from gr oundwater supplies, the City can implement various stages of its Water Shortage Conti ngency Plan to balance water demands with available supplies during each year of the projected five consecutive year drought.

OPTIONAL PLANNING TOOL WORKBOOK

DWR has deemed the “Planning Tool Worksheet” as optional and the City is not required by DWR to use the tool. The City has provided sufficient water supplies to its customers, including during long-term droughts and years with historically high water demands. The City has also been able to provide water se rvice to meet maximum day water demands for these years, including during the summer months. The City also obtains its water supplies from managed groundwater basins which are not subject to seasonal fluctuation.

Consequently, an evaluation regarding wa ter supplies on a monthly basis was not considered.

CHAPTER 8

WATER SHORTAGE CONTINGENCY PLAN

LAY DESCRIPTION – CHAPTER 8

WATER SHORTAGE CONTINGENCY PLAN

Chapter 8 (Water Shortage Co ntingency Plan) of the City ’s 2025 Plan discusses and provides the following:

 The City’s Water Shortage Contingen cy Plan is a detailed approach which presents how the City intends to act, or respond, in the case of an actual water shortage contingency.
 Preparation of the City’s “Annual Wa ter Supply and Demand Assessment” (or Annual Assessment) is discusse d. The City is required to submit annually an Annual Assessment. The Annual Assessment includes a review of the City’s “unconstrained” water demands for the current year and for a potential upcoming single dry year. Unconstrained water demands represent the City’s water demands prior to any “response actions” the City may invoke pursuant to the City’s Water Shortage Contingency Plan.
 The City will manage water supplies to minimize the adverse impacts of water shortages. The City’s plan for water usage during periods of shortage is designed to incorporate six standard water short age levels corresponding to progressive ranges from up to a 10, 20, 30, 40, and 50 percent shortage, and greater than a 50 percent shortage.
 For each declared water supply shortage level, customers will be required to reduce their consumption by the percentage specified in the corresponding water supply shortage level.

2025 Urban Water Management Plan

City of Glendale

 For each declared water supply shortage le vel, the City has established response actions to reduce demand on water supplie s and to reduce any shortage gaps in water supplies. These demand reducti on actions include irrigation and other outdoor use restrictions, rate structure changes, and other water use prohibitions.  The operational changes the City will c onsider in addressing water shortages on a short-term basis are discussed and incl ude improved monito ring, analysis, and tracking of customer water usage to enforce demand reduction measures.  The City’s Emergency Response Plan is summarized. The Emergency Response Plan provides the management, procedures, and designated actions the City and its employees will implement during emergency situations (including catastrophic water shortages) resulting from natural disasters, system failures, and other unforeseen circumstances.
 The preparation of the City’s seismic risk assessment and mitigation plan is discussed. The locations of earthquake faults in the vicinity of the City’s water service area are provided.
 The effectiveness of the shortage respons e actions for each of the City’s standard water shortage levels is presented. The City has been able to provide sufficient water supplies to its customers, including during long-term droughts and years with historically high water demands.
 The communication protocols implemented by the City when it declares any water shortage level are presented.
 The compliance and enforcement procedur es associated with City’s standard water shortage levels are presented.
 The legal authorities associated with City’s standard water shortage levels are presented.
 The financial consequences associated with City’s standard water shortage levels are presented.
 The City will evaluate the need for re vising the Water Shortage Contingency Plan in order to resolve any water shortage gaps, as necessary. The steps necessary

2025 Urban Water Management Plan

City of Glendale

for the City to adopt and amend its Wa ter Shortage Contingency Plan are presented.

The following Water Shortage Contingency Plan includes references to Chapters and Sections from the City of Glendale’s 2025 Urban Water Management Plan:

WATER SUPPLY RELIABILITY ANALYSIS

CWC 10632.

(a)(1) The analysis of water supply reliability conducted pursuant to Section 10635.

CWC 10632.5.

(a) In addition to the requirements of paragraph (3) of subdivision (a) of Section 10632, beginning January 1, 2020, the plan shall include a se ismic risk assessment and mitigation plan to assess the vulnerability of each of the various facilities of a water system and mitigate those vulnerabilities.

The City’s sources of supply were discussed in Section 6.2 of the 2025 Plan and consist of groundwater from the San Fernando and Verdugo Basins and treated imported water purchased from MWD. In addition, the City provides recycled water. The San Fernando and Verdugo Basins are adjudicated and groundwater supplies are managed. The reliability of the various sources of supply are discussed in Chapter 7 of the 2025 Plan.

Imported water supplies may be impacted in the event MWD impl ements its WSAP due to a water supply shortage. A seismic risk assessment and mitigation plan is discussed in Section 8.4.6.

2025 Urban Water Management Plan

City of Glendale

ANNUAL WATER SUPPLY AND DEMAND ASSESSMENT PROCEDURES

CWC 10632.

(a) Every urban water supplier shall prepare and adopt a water shortage contingency plan as part of its urban water management plan that consists of each of the following elements

CWC 10632.

(a)(2) The procedures used in conducting an annual water supply and demand assessment that include, at a minimum, both of the following:

(A) The written decision-making process that an urban water s upplier will use each year to determine its water supply reliability.

(B) The key data inputs and assessment methodology used to evaluate the urban water supplier’s water supply reliability for the current year and one dry year, including all of the following:

(i) 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.

(ii) Current year available supply, considering hydrological and regulatory conditions in the current year and one dry year. The annual supply and demand assessment may consider more than one dry year sole ly at the discretion of the urban water supplier.

(iii) Existing infrastruc ture capabilities and plausible constraints.

(iv) A defined set of locally applicable eval uation criteria that are consistently relied upon for each annual water supply and demand assessment.

(v) A description and quantification of each source of water supply.

CWC 10632.1.

An urban water supplier shall conduct an annual water supply and demand assessment pursuant to subdivision (a) of Section 10632 and, on or before July 1 of each year, submit an annual water shortage assessment report to the department with information for anticipated shortage, triggered shortage response actions, compliance and en forcement actions, and communication actions consistent with the supplier’s water shortage contingency plan. An urban water supplier that relies on imported water from the State Water Project or the Bureau of Reclamation shall submit its annual water supply and demand assessment within 14 days of receiving its final allocations, or by July 1 of each year, whichever is later.

By July 1 st of every year, the City is require d to submit an “Annual Water Supply and Demand Assessment” (Annual Assessment) in accordance with DWR’s guidance and

2025 Urban Water Management Plan

City of Glendale

requirements. The Annual Assessment will includes a review of the City’s unconstrained water demands (i.e. water demands prior to any projected response actions the City may trigger under this Water Shortage Contin gency Plan) for the current year and the upcoming (potential single dry) year. The A nnual Assessment also includes information regarding anticipated short ages, triggered shortage response actions, compliance and enforcement actions, and communication acti ons consistent with the City’s Water Shortage Contingency Plan.

During the preparation of each Annual Asse ssment, the City will evaluate the adequacy of its water supplies for the current and upco ming years. The evaluation will include a review of water supplies for at least a single dry year.

DECISION-MAKING PROCESS

During the third quarter of each fiscal year the City will review its water demands from the initial six months along with the current groundwater basin conditions and local hydrology.

This information will be used to help dev elop the Annual Assessment. A draft of the Annual Assessment will be circ ulated internally within t he City for peer review and comment. Based on comments received, a redr aft will be prepared and provided to City managers during the Spring of each year. The dr aft will subsequently be provided to the General Manager for final review. If necessary, a final draft of the Annual Assessment will be provided to the City Council for review and included in the agenda as part of a Council meeting such that it can be approved and any recommended specific shortage response actions may be enacted. The final Annual A ssessment will be provided to DWR no later than July 1 of each year.

The Annual Assessments will be instrumental in providin g guidance to the City for decisions regarding potential declarations of a water supply shortage and implementation of water reduction stages, inst ituting mandatory water restri ctions, promoting water use efficiency and conservation programs, water rates and drought rate surcharges, and the

2025 Urban Water Management Plan

City of Glendale

necessity of pursuing alternative water supplies. This process will help ensure adequate water supplies resources are available to the City.

DATA AND METHODOLOGIES

The key data inputs and methodologies which wi ll be evaluated by the City during the preparation of the Annual Assessment will include the following:

1) Evaluation Criteria: The locally applicable evaluation criteria used to prepare the Annual Assessment will be iden tified. The evaluation cr iteria will include, but is not limited to, an analysis of current lo cal hydrology (including rainfall and groundwater levels), current water demands, a review of water system improvement plans which may impact infrastr ucture availability, and water quality regulations which may impact groundwater availability.

2) Water Supply: A description of each available water supply source will be provided.

The descriptions will include a quantification of each available water supply source and will be based on review of current production capacities, historical production, Urban Water Management Plans, and prior water supply studies (including Water Supply Assessments and/or Master Plans).

3) Unconstrained Water Demand: The potential unconstrained water demands during the current year and the upcoming (potential single dry) year will be reviewed. The review will include factors such as w eather, existing and projected land uses and populations, actual customer consumption and water us e factors, monthly Urban Water Supplier Monthly Reports, existing water shortage levels (see Section 8.3), and existing water conservation ordinances (see Section 9.1).

4) Planned Water Use for Current Year Considering Dry Subsequent Year: The water supplies available to meet the demands during the current year and the upcoming

2025 Urban Water Management Plan

City of Glendale

(potential single dry) year will be considered and identified by each type of supply.

The evaluation will include factors such as estimated water demands, weather, groundwater basin operating safe yields, wa ter quality results, existing available pumping capacities, imported water allocations, contractual obligations, regulatory issues, use of emergency interconnection s, and the costs associated with producing each water supply source.

5) Infrastructure Considerations: The c apabilities of the wate r distribution system infrastructure to meet the water demands during the current year and the upcoming (potential single dry) year will be considered. Available production capacities (e.g. groundwater well capacities) and distri bution system water losses (see Section

4.3) will be reviewed. In addition, capi tal improvement and r eplacement projects, as well as potential projects which may increase water system and production capacities (see Section 6.2.10), will be considered.

SIX STANDARD WATER SHORTAGE LEVELS

CWC 10632.

(a)(3)(A) Six standard water shortage levels corresponding to progressive ranges of up to 10, 20, 30, 40, and 50 percent shortages and great er than 50 percent shortage. Urban water suppliers shall define these shortage levels based on the suppliers’ water supply conditions, including percentage reductions in water supply, changes in groundwater levels, changes in surface elevation or level of subsidence, or other changes in hydrological or other local conditions indica tive of the water supply available for use.

Shortage levels shall also apply to catastrophic interruption of water supplies, including, but not limited to, a regional power out age, an earthquake, and other potential emergency events.

(a)(3)(B) An urban water supplier with an existing water shortage contingency plan that uses different water shortage levels may comply with the requirement in subparagraph (A) by developing and including a cross-reference rela ting its existing categories to the six standard water shortage levels.

2025 Urban Water Management Plan

City of Glendale

The City has a legal responsibility to provi de water utility services, including water for residential, commercial, industrial, public authority, and for public fire hydrants and private fire services. The City will manage water s upplies prudently to minimize the adverse impacts of water shortages. The City’s plan for water usage during periods of shortage is designed to incorporate six standard water shortage levels corresponding to progressive ranges from up to 10, 20, 30, 40, and 50 per cent shortages and greater than 50 percent shortage. Water shortage trigger mechanisms have been established to ensure that this policy is implemented.

For each declared water supply shortage level, customers will be required to reduce their water consumption by the percentage spec ified in the corresponding water supply shortage level.

The City’s Municipal Code Section 13.36. 070 “Water Conservation” previously established five (5) water shortage levels (a copy is provided in Appendix G). In accordance with the California Water Code in which urban water suppliers are required to define six standard water shortage level, the City has developed the crosswalk illustrated below (also included in the Ci ty’s 2020 Plan) that tr anslated the City’s previously established shortage levels to the mandated standard shortage levels. Table 8-1 also provides a cross-reference between the City’s previously established shortage levels and the mandated standard shortage levels.

SHORTAGE RESPONSE ACTIONS

CWC 10632.

(a)(4) Shortage response actions that align wi th the defined shortage le vels and include, at a minimum, all of the following:

(A) Locally appropriate supply augmentation actions.

(B) Locally appropriate demand reduction ac tions to adequately respond to shortages.

(C) Locally appropriate operational changes.

(D) Additional, mandatory prohibitions against specif ic water use practices that are in addition to state-mandated prohibitions and appropriate to the local conditions.

(E) For each action, an estimate of the extent to which the gap between supplies and demand will be reduced by implementation of the action.

SUPPLY AUGMENTATION

As discussed in Chapter 6, the City’s so urces of water supply include groundwater produced from the San Fernando and Ver dugo Basins and imported surface water

2025 Urban Water Management Plan

City of Glendale

purchased from MWD. As noted in Section 8. 2, the City is required to annually prepare and submit an Annual Assessment which will include a review of water supplies available to meet water demands for the current and upcoming years. If the City is currently in, or considers entering into, one of the standard wa ter shortage levels identified in Section

8.3, the City will consider the water supply augmentation actions described below.

For each water shortage level discussed in Section 8.3, the City will consider supplementing its existing water supplies th rough purchase of additional imported water supplies. Due to previous critically dr y conditions, MWD developed the “Water Supply Allocation Plan” whereby available supplies are equitably allocated to its member agencies, including the City. The WSAP establ ishes ten different shortage levels and a corresponding drought allocation to each me mber agency. Based on the shortage level established by MWD, the WSAP provides a reduced drought allocation to a member agency for its M&I retail demand. The ratio of MWD water supply drought allocation to local water supply will change based on t he WSAP stage. The MWD drought allocation can be used to make Full Service water deliver ies at the Tier 1 rate up to a Tier 1 allocation. Any Full Service water delivered in excess of a drought allocation is subject to a penalty rate in addition to the normal rate paid for the water.

In addition to the WSAP, MWD describes s upply augmentation actions in its Regional 2025 UWMP, which is incorporated by referenc e. MWD’s primary first response to any gap between core supplies (from the State Water Project and Colorado River) and demand is to make optimal use of its supply augmentation options, consisting of drawing from flexible supply programs and storage reserves. MWD has developed and actively manages a portfolio of water supply progra ms including water transfer, storage, and exchange agreements. MWD pursues voluntary water transfer and exchange programs to help mitigate supply/demand imbalances and provide additiona l dry-year supply sources. In addition, MWD has developed si gnificant storage capacity in reservoirs, conjunctive use, and other groundwater storage programs totaling approximately 6.0 million AF. Based on MWD’s historical and on-going water supply and storage programs

2025 Urban Water Management Plan

City of Glendale

and management practices, the City can potentially continue relying on purchased imported water supplies from MWD for ad equate supply augmentation in response to each of the standard water shortage levels identified in Section 8.3.

DEMAND REDUCTION

The City may establish water shortage response actions to reduce demand on water supplies. These demand reduction actions in clude irrigation and other outdoor use restrictions, rate structure changes, and ot her water use prohibitions. Depending on the percent reduction in the City’s water s upply and corresponding water shortage level, regulations are made to conserve water and reduce the shortage gap in normal supply levels. Many demand reduction actions, identified as voluntary or mandatory conservation measures, are applicable to all levels of water shortages. The structure of water shortage levels are designed to str ongly encourage customers with high per capita usage to achieve proportionally greater reduction than thos e with low usage. Violations of these demand reduction actions will be considered waste and an unreasonable use of water.

Table 8-3 describes each demand reduction action and its effect on reducing the shortage gap.

A full listing of the restrictions/prohibitions associated with each shortage level is provided below.

No Water Waste Policy

There is in effect at all times in the city a "no water waste" policy as set forth herein.

Except as otherwise provided in this chapter, at no time shall any person make, cause, use, or permit the use of water from the department for residential, commercial, industrial, agricultural, governmental, or any other purpose in a manner contrary to any provision of this chapter or in an amount in excess of that use permitted by the conservation phase

2025 Urban Water Management Plan

City of Glendale

then in effect pursuant to action taken by the city council in accordance with the provisions of this chapter.

A. Water Use Restrictions.

1. Hose Washing. Potable water shall not be used for hose washing of sidewalks, walkways, driveways, or parking areas, tennis courts, patios, porches or other paved areas, except: (a) where necessary to alleviate safety or sanitary hazards, and then only by use of a handheld bucket or similar container or a hand-held hose equipped with a water shut-off device; (b) when using a low-volume high-pre ssure cleaning machine; or (c) that flammable or other dangerous substanc es may be disposed of by direct hose flushing by public safety officers for the benefit of public health and safety.

2. Overspray or Runoff. There shall be no use of water for any purpose which results in overspray, runoff in flooding or runoff onto hardscape, driveways, streets, adjacent lands or into gutters.

OPERATIONAL CHANGES

During a water supply shortage situation, the City will manage its water supply resources to provide sufficient water supplies capable of meeting the demands of its customers.

Section 8.4.1 describes the City’s standard water shortage levels and associated demand reduction measures. Section 8. 4.2 describes the City’s water supply sources and water supply augmentation actions available. The supply augm entation actions and demand reduction measures, when implemented, may potentially result in short-term operational changes which are necessary to allow the City to utilize all available water supply sources in response to water shortage situations.

As noted in Section 8.2, the City is r equired to annually prepar e and submit an Annual Assessment which will include a review of th e water supplies availa ble to meet water demands for the current and upcoming years. Preparation of the Annual Assessment will assist the City in determining any potential operational changes. In addition, the City’s standard water shortage levels and the a ssociated demand reduc tion measures, in conjunction with the City’s existing Demand Management Measures (discussed in Chapter 9), will be essential to the City in reducing water demands during any water shortage period. The operational changes the City will consider in addressing non- catastrophic water shortages on a short-term basis include the following:

 Improved monitoring, analysis, and tracki ng of customer water usage to enforce demand reduction measures
 Optimized production from existing available water supply sources

2025 Urban Water Management Plan

City of Glendale

 Potential use of emergency supply sour ces, including emergency interconnections  Potential blending of water supply resources
 Improved monitoring, maintenance, and repairs to reduce water distribution system losses

ADDITIONAL MANDATO RY RESTRICTIONS

The mandatory restrictions which are implem ented by the City to reduce customer demands are discussed in Section 8.4.2. There are no additional mandatory restrictions planned at this time.

EMERGENCY RESPONSE PLAN

Catastrophic water shortages are incorporat ed in the City’s standard water shortage levels (identified in Section 8.3) and the associated demand reduction measures (described in Section 8.4. 2). In addition to the wa ter supply augmentation actions (Section 8.4.1) and potential op erational changes (Section 8. 4.3) which the City may consider in order to continue providing sufficient water supplies, the City will review and implement any necessary steps included in its “Emergency Response Plan”.

As part of the “America’s Water Infrastructure Act of 2018”, community water systems serving a population greater than 3,300 people, including the City, are required to review and update their “Risk and Resilience A ssessment” (RRA) and the associated “Emergency Response Plan” (ERP) every five (5) years. However, due to security concerns regarding the submitting of these reports, water systems are required to submit certifications to the USEPA, from Marc h 31, 2025 and December 31, 2026, confirming the current RRA and ERP have been reviewed and updated.

2025 Urban Water Management Plan

City of Glendale

The City’s RRA, updated in March 2025, eval uates the vulnerabilities, threats, and consequences from potential hazards to the City’s water system. The City prepared its RRA (which is incorporated by reference) by evaluating the following items:

 Natural hazards and malevolent acts (i.e., all hazards);  Resilience of water facility infrastructure (including pipes, physical barriers, water sources and collection, treatment, storage and distribution facilities, and electronic, computer and other automated systems);
 Monitoring practices;
 Financial systems (e.g., billing systems);
 Chemical storage and handling; and
 Operation and maintenance.

The City’s RRA evaluated a series of potential malevolent acts, natural hazards, and other threats in order to estimate the potentia l “monetized risks” (i.e. associated economic consequences to both the water system a nd surrounding region, and the likelihood of occurrence) associated with the City’s wate r facility assets. The cost-effectiveness of implementing potential countermeasures to reduce risks was also reviewed.

The City’s ERP, updated in September 2025, provides the management, procedures, and designated actions the City and its employees will implement during emergency situations (including catastrophic water shortages) resulting from natural disasters, system failures and other unforeseen circumstances. The City’s ERP (which is incorporated by reference) provides the guidelines for evaluating an em ergency situation, procedures for activating an emergency response, and details of the diffe rent response phases in order to ensure that customers receive a reliable and adequate supply of potable water. The scope of the ERP includes emergencies which directly affect the water system and the ability to maintain safe operations (such as a chlo rine release, and earthquake or a threat of

2025 Urban Water Management Plan

City of Glendale

contamination). The ERP also incorporates the results of City’s RRA and includes the following:

 Strategies and resources to improv e resilience, including physical and cybersecurity
 Plans and procedures for responding to a natural hazard or malevolent act  Actions and equipment to lessen the impact of a natural hazard or malevolent act  Strategies to detect natural hazards or malevolent act

The City will review the ERP for procedures regarding the utilization of alternative water supply sources in response to water suppl y shortages, including during the standard water shortage levels. The City will also review applicable procedures described in the ERP regarding any necessary temporary shutdow n of water supply facilities, including appropriate regulatory and public notifications.

SEISMIC RISK ASSESSMENT AND MITIGATION PLAN

CWC 10632.5.

(a) In addition to the requirements of paragraph (3) of subdivision (a) of Section 10632, beginning January 1, 2020, the plan shall include a se ismic risk assessment and mitigation plan to assess the vulnerability of each of the various facilities of a water system and mitigate those vulnerabilities.

(b) An urban water supplier shall update the seismic risk assessment and mitigation plan when updating its urban water management plan as required by Section 10621.

(c) An urban water supplier may comply with this section by submitting, pursuant to Section 10644, a copy of the most recent adopted local hazard mitigation plan or multihazard mitigation plan under the federal Disaster Mitigation Act of 200 0 (Public Law 106-390) if the local hazard mitigation plan or multihazard mitigation plan addresses seismic risk.

The City prepared a “Hazard Mitigation Plan” in 2018 which identified methods to assess significant natural hazards (including earth quakes) affecting areas throughout the City,

2025 Urban Water Management Plan

City of Glendale

and the mitigation strategies necessary to reduce risks, including seismic risk. The City’s Hazard Mitigation Plan is provided in Appendix H.

The County of Los Angeles prepared a “All -Hazards Mitigation Plan” in 2025 which identified methods to assess significant natural hazards (including earthquakes) affecting areas throughout Los Angeles County, and the mitigation strategies necessary to reduce risks, including seismic risk. The County’s All-Hazards Mitigation Plan is provided in Appendix I.

The California Geological Survey has publis hed the locations of numerous faults which have been mapped in the S outhern California region. Although the San Andreas fault is the most recognized and is capable of producing an earthquake with a magnitude greater than 8 on the Richter scale, some of the lesser-known faults have the potential to cause significant damage. The locations of these eart hquake faults in the vicinity of the City’s water service area are provided in the figure bel ow. The faults that are located in close proximity to and could potentially cause significant shaking in the City’s water service area include the Verdugo fault, the Raymond Fault, Sierra Madre fault, and the Hollywood fault.

The California Geological Survey provides earthquake hazard maps 4 based on the Modified Mercalli Intensity (MMI) scale, which measures earthquake shaking intensity and its impacts on people, objects, and buildings. The area within the City’s service area has an MMI of approximately 9.4 calculated based on the level of shaking that has a 2 percent chance of being exceeded in 50 years (or the level of shaking with an approximate 2,500- year average repeat time). An MMI at this intensity (violent shaking) can result in buildings shifted off foundations, cracked, or tilted, the ground cracked, and underground pipes broken. As discussed in Section 8. 4.5, the City has prepared an Emergency Response Plan which provides the management, procedures, and designated actions the City and its employees will implement during emergency situations resulting from natural

disasters, including during earthquakes, to ens ure that customers receive a reliable and adequate supply of potable water. The City’s ERP is incorporated by reference.

SHORTAGE RESPONSE ACTION EFFECTIVENESS

The effectiveness of the shortage response actions for each of the standard water shortage levels identified in Section 8.3 is evident in the City’s historical ability to meet its customer’s water demands in response to a water supply shortage. In addition, the City imposes water consumption regulations and restrictions, and supports local agencies in efforts to enforce regulations and prohibitions on water use. The effectiveness of each of the City’s shortage response actions, in order to reduce any potential gaps between supply and demand, has been quantified in t he expected demand reduction provided in Table 8-2 and Table 8-3.

Section 6.1 provides a tabulation of the Ci ty’s historical annual water demands for each water supply source. During the past 15 years, the City experienced a five consecutive year drought within its service area from CY 2011 to CY 2015. Throughout this extended dry year period, the City’s annual water production ranged from 24,421 AF to 29,520 AF, with an average of approximately 27,724 AF. In addition, historical records indicate the City previously produced 34,262 AF in CY 2004. The City has been able to provide sufficient water supplies to its customers, including during long-term droughts and years with historically high water demands. In addition, the City has been able to provide water service to meet maximum day water demands for these years, including during the summer months.

The City’s water demands during the most recent five years (from FY 2021 to FY 2025) averaged approximately 23,055 AFY. Due to conser vation efforts and demand management measures (discussed in Chapter 9), the City’s recent water demands have been less than its historical water demands, in cluding during long-t erm droughts. The City’s projected water demands (during normal, single dry, and a five consecutive year

2025 Urban Water Management Plan

City of Glendale

drought) are provided in Section 7.2.3 and are anticipated to incorporate similar reductions in water use rates as a result of the shortage response actions, ongoing conservation efforts, and demand management measures. Because the City’s projected water demands are similar to or less than its historical water demands, it is anticipated the City will be able to continue providing su fficient water supplies to its customers to meet projected water demands, including duri ng long-term droughts. In addition, as discussed in Section 8.4.1, based on historical and on-going management practices, the City will be able to continue relying on its water supply source from the San Fernando Basin and from imported water purchases for adequate supply augmentation in response to each of the standard water shortage levels identified in Section 8.3.

The City’s Municipal Code Chapter 13.36 “W ater Conservation” includes a Mandatory Water Conservation Plan. The City previous ly declared a water supply shortage in 2015 and established water-use restrictions and regul ations equivalent to the City’s standard water shortage level 2 identified in Section 8.3. During this water shortage period, the City was able to reduce water demands and provide sufficient water supplies to its customers.

Based on the City’s ability in meeting water demands during past water supply shortages, adopted water shortage levels, adjusted operating safe yields, and long-term droughts, it is anticipated that the City will be able to continue providing sufficient water supplies to its customers during any of its standar d water shortage levels. Although adequate supplies are anticipated, the cost of those water supplies may become incrementally more expensive. The City will enact varying levels of its water shortage contingency plan to encourage retail customers to reduce water consumption and at the same time reduce the need to use the more expensive water s upplies. Notwithstanding, the effectiveness of each of the City’s shortage response actions, in order to reduce any potential gaps between supply and demand, has been quantifi ed in the expected demand reduction provided in Table 8-2 and Table 8-3. The e ffectiveness of the City’s shortage response actions is based on the City’s water demands prior to 2015 (unconstrained demands).

The City reduced its water demands in 2015 in response to the Governor’s April 1, 2015

2025 Urban Water Management Plan

City of Glendale

Executive Order B-29-15 which mandated statewide reduction in water use of 25 percent.

The City’s actual water demand reduction duri ng this period was used to estimate the extent of water use reductions for the City ’s Water Shortage Stages. The City’s Water Shortage Levels 1, 2, 3, 4, 5, and 6 are expected to reduce water demands by up to 10%, 20%, 30%, 40%, 50%, and greater than 50%, respectively.

Emergency regulations previously adopted by the SWRCB pursuant to Executive Order N-7-22 (issued on March 28, 2022 by California Governor Gavin Newsom) required urban water suppliers to implement Level 2 of their Water Shortage Contingency Plans meant to address up to a 20% shortage of water suppl ies. The regulations also required urban water suppliers to establish a ban on irrigat ing non-functional tu rf at commercial, industrial, and institutional properties (including grass in front of or next to large industrial or commercial buildings). The ban did not include watering turf that is used for recreation or other community purposes, water used at residences or water to maintain trees.

Pursuant to Executive Order N-5-23 issued on March 24, 2023 by California Governor Gavin Newsom, the requirement for urban water suppliers to implement Level 2 of their Water Shortage Contingency Plans was removed. As of June 5, 2024, SWRCB statewide water conservation emergency regulations have expired and there are no current statewide water conservation emergency regulations.

FINANCIAL CONSEQUENCES OF WSCP

CWC 10632.

(a)(8) A description of the financial consequences of, and responses for, drought conditions, including, but not limited to, all of the following:

(A) A description of potential revenue reducti ons and expense increases associated with activated shortage response actions described in paragraph (4).

(B) A description of mitigation actions need ed to address revenue reductions and expense increases associated with activated shortage response actions described in paragraph (4).

(C) A description of the cost of compliance with Chapter 3.3 (commencing with Section 365) of Division 1. [retail urban suppliers only]

During periods of water supply shortages, state-mandated water use restrictions, or emergency conditions, the City may require its customers to reduce demands below levels projected under the current water rate structure. Under any of these circumstances, the City may experience a decrease in revenues that may result in insufficient funds to meet projected expenses.

During a catastrophic interruption of water supplies, prolonged drought, or water shortage of any kind, the City will experience a reduction in revenue due to reduced water sales.

Throughout this period of time , expenditures may increase or decrease with varying circumstances. Expenditures may increase in the event of significant damage to the water system, resulting in emergency repairs. Expenditures may also decrease as less water is pumped through the system, resulting in lower power costs.

The City has implemented a tiered rate structure for residential customers to meet service costs and discourage high water use. In addi tion, on June 12, 2018, the City Council adopted a new water rate fee structure effectiv e July 1, 2018. In anticipation of possible drought conditions in California, the new rate-structure also included an additional fee, or Drought Charge. The Drought Charge is specif ically related to drought conditions and

2025 Urban Water Management Plan

City of Glendale

would go into effect upon the approval by the City Council of any of the four phases of the City’s mandatory water conservation ordinance. The purpose of the Drought Charge is to keep the utility financially secure should California enter into a prolonged drought period and revenues from consumption declined in response to mandatory conservation.

In addition, the Drought C harge encourages water conserva tion among all customers.

The Drought Charge was designed such that customers who meet the curtailment target will likely not experience an increase in their total bill. A water rate sheet showing current rates is provided in Appendix J.

MONITORING AND REPORTING

CWC 10632.

(a)(9) For an urban retail water supplier, moni toring and reporting requirements and procedures that ensure appropriate data is collected, tracked, and analyzed for purposes of monitoring customer compliance and to meet state reporting requirements.

The City meters all service connections in its distribution system. The City maintains all of its meters and monitors them thro ugh its computerized billing system. The computerized billing systems will detect me ters that have unusually high meter read.

These meters are then further investigated. The City tests, repairs, and/or replaces all meter as needed.

The City’s Water Engineering Section monitors and reports to the State water use, water conservation, and mandatory conservation restrictions and enfor cement when such restrictions are in place. The Water E ngineering Section gathers and collates water production information from the Water Operations Section, and enforcement of “customer compliance” actions, when mandatory conserva tion is in place, from the Customer Service Section. When new State requirements are implemented, the Water Engineering

Section may consult with the City Attorn ey’s Office as needed to ensure reporting compliance.

WSCP REFINEMENT PROCEDURES

CWC 10632.

(a)(10) Reevaluation and improvement procedures for systematically monitoring and evaluating the functionality of the water shortage contingen cy plan in order to ensure shortage risk tolerance is adequate and appropriate wate r shortage mitigation strategies are implemented as needed.

The City’s Water Shortage Contingenc y Plan has been prepared as an adaptive management plan. As discussed in Section 8. 9, the City will m onitor and report on the implementation of the Water Shortage Conti ngency Plan. The City will review the implementation results for any current or potential shortage gaps between water supplies and demands. The City will evaluate th e need for revising the Water Shortage Contingency Plan in order to resolve any shortage gaps, as necessary. The City will consider the following potential revisions in the event of a potential shortage gap:

 Implementation of addition al public outreach, educ ation, and communication programs (in addition to the programs discussed in Chapter 9).  Implementation of more stringent water use restrictions under the standard water shortage levels (discussed in Section 8.4)
 Implementation of stricter enforcement actions and penalties (discussed in Section

8.6)
 Improvements to the water supply augment ation responses (discussed in Section

8.4.1), as well as any associated operational changes (discussed in Section 8.4.3) which may be required

2025 Urban Water Management Plan

City of Glendale

 Incorporation of additional actions reco mmended by City staff or other interested parties

The City will use the monitoring and repor ting data to evaluate the ability for these potential revisions to resolve any short age gaps which may occur within the standard water shortage levels.

This Water Shortage Contingency Plan is adopted as part of the City’s 2025 Urban Water Management Plan adoption process discussed in Section 10.3. It is anticipated the City will review, revise, and adopt an updated Wate r Shortage Contingency Plan as part of preparing its 2030 Urban Water Management Plan as necessary. However, the City will continue to review the monitoring and r eporting data, and if needed, update the Water Shortage Contingency Plan more frequently. Any updates to the City’s Water Shortage Contingency Plan will include a public heari ng and adoption process by the City Council (see Section 8.12).

SPECIAL WATER FEATURE DISTINCTION

CWC 10632.

(b) For purposes of developing the water shortage contingency plan pursuant to subdivision (a), an urban water supplier shall analyze and define water features that are artificially supplied with water, including ponds, lakes, waterfalls, and fo untains, separately from swimming pools and spas, as defined in subdivision (a) of Section 115921 of the Health and Safety Code.

The City’s Water Shortage Contingency Plan defines “decorative water features” as water features which are artificially supplied wi th water, including ponds, lakes, waterfalls, and fountains, but excluding pools and spas. In general, there are additional health and safety considerations in the water supplied to pools and spas compared to decorative water features. As a result, the City’s Wate r Shortage Contingency Plan has reviewed the
