WATER SHORTAGE CONTINGENCY PLAN
LAY DESCRIPTION – CHAPTER 8
WAT
ER 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 Water Supply and Demand Assessment” (or Annual Assessment) is discusse d. The City is required to submit annually an Annual As
sessment. 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 corr esponding 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.
EXHIBIT A
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.

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.

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
2025 Urban Water Management Plan
City of Glendale
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
2025 Urban Water Management Plan
City of Glendale
response actions, enforcement actions , and monitoring and reporting programs separately for decorative water features and for pools and spas, as applicable.
