Water Shortage Contingency PlanThis Water Shortage Contingency Plan (WSCP) is a strategic plan that the Victorville Water District uses to prepare for and respond to water shortages.A water shortage occurs when water supply available is insufficient to meet the normally expected customer water use at a given point in time. A shortage may occur due to a number of reasons, such as water supply quality changes, climate change, drought, regional power outage, and catastrophic events (e.g., earthquake).Additionally, the Stateof California (State) may declare a statewide drought emergency and mandate that water suppliers reduce demands, as occurred in 2014.The WSCP serves as the operating manual that Victorville Water District (VWD) will use to prevent catastrophic service disruptions through proactive, rather than reactive, mitigation of water shortages. This WSCP provides a process for an Annual Water Supply and Demand Assessment and structured steps designed to respond to actual conditions. This level of detailed planning and preparation provide accountability and predictability and will help VWD maintain reliable supplies and reduce the impacts of any supply shortages and/or interruptions.This WSCP was prepared in conjunction with VWDs 2025 Regional Urban Water Management Plan (RUWMP) and is a standalone document that can be modified as needed. This document is compliant with the California Water Code (CWC) Section 10632 and incorporated guidance from the State of California Department of Water Resources (DWR) UWMP Guidebook.

Victorville Water District 1-3 Water Shortage Contingency Plan
1.1 Water Supply Reliability Analysis As part of the 2025 RUWMP, VWD completed a water supply reliability analysis for normal, single-dry, and five-year consecutive dry year periods. As described in Chapter 16.8 of VWDs 2025 RUWMP, the effects of a local drought are not immediately recognized because the region uses the local groundwater basins to simulate a large reservoir for long-term storage. VWD is able to pump additional groundwater to meet increased demands in dry years and participates in efforts to replenish the basins with imported and local water through regional recharge programs. Based on the analysis, VWD does not anticipate any supply shortage due to single or consecutive dry years. Even though localized drought conditions should not affect supply, VWD participates in several ongoing water conservation measures and regional recharge projects to optimize and enhance the use of regional water resources. VWD will use this WSCP as appropriate to reduce the demand during critical drought years or other supply emergencies. A Drought Risk Assessment was also performed to analyze supply reliability for the next five years, 2026 through 2030. Similarly, the results show that VWDs water supply is reliable and is not expected to see impactful change under drought conditions. 1.2 Annual Water Supply and Demand Assessment As an urban water supplier, VWD must prepare and submit an Annual Water Supply and Demand Assessment (Annual Assessment) per CWC Section 10632.1. Starting in 2022, the Annual Assessment will be due by July 1 of every year. The Annual Assessment is an evaluation of the near-term outlook for supplies and demands to determine whether the potential for a supply shortage exists and whether there is a need to trigger a WSCP shortage level and response actions in the current calendar year to maintain supply reliability. This process will take place at the same time each year based on known circumstances and information available to VWD at the time of analysis and can be update or revised at any time if circumstances change. VWD will establish and convene an internal WSCP Team to conduct the Annual Assessment each year. The WSCP may include the following staff and is led by the Water Conservation Department: General Manager Water Supply/Engineering Staff Water Conservation Staff Public Works Staff Finance The Annual Assessment procedure, including key data inputs and evaluation criteria, is summarized in Table 1-1.

Annual Assessment Procedure TIMING ASSESSMENT ACTIVITIES PROCEDURE, KEY DATA INPUTS, EVALUATION CRITERIA AND OTHER CONSIDERATIONS STAFF RESPONSIBLE Oct-Nov Estimate unconstrained demands for coming year Demands will be estimated based on water sales forecasts from annual budget or prior year demands plus any anticipated changes Water Supply/Engineering Oct-Nov Estimate available supplies for the year, considering the following year will be dry Previous year supplies (from Electronic Annual Report Water Supply) will be reviewed and compared to estimated demands for the coming up year to determine estimated supplies. VWD will coordinate with Mojave Water Agency to determine availability of Regional Recharge and Recovery Project water supply. Water Supply/Engineering Jan - Feb Consider potential constraints that may impact supply delivery Identify any known regional or VWD infrastructure issues that may pertain to near-term water supply reliability, including repairs, construction, and environmental mitigation measures that may temporarily constrain capabilities, as well as any new projects that may add to system capacity. Identify any facilities out of service due to water quality problems, equipment failure, etc. that may impact normal water deliveries. Water Supply/Engineering Feb Convene WSCP Team to conduct Annual Assessment Compare supplies and demands and discuss any constraints that may impact supply delivery. If the potential for a shortage exists, determine which shortage response level and actions are recommended to reduce/eliminate the shortage. Additionally, if the State declares a drought state of emergency and requires demand reductions, the WSCP Team will determine which water shortage level and response actions are needed to comply with the State mandate. WSCP Team Jun City of Victorville (City) Council review and action If the potential for a shortage exists or the State has mandated demand reductions, the results of the Annual Assessment will be presented to the VWD City Council, including the recommended shortage level and response actions. City Council may order the implementation of a shortage level and will adopt a resolution declaring the applicable water shortage level. General Manager City Council On-going Implement WSCP actions, if needed Relevant members of VWD staff will implement shortage response actions associated with the declared water shortage level WSCP Team By July 1 Submit Retail Annual Assessment Send Final Retail Annual Assessment to DWR WSCP Team

1.3 Six Standard Water Shortage Levels Water agencies relying solely on groundwater sources which are being managed under an adjudication, such as the VWD, are less likely to experience water shortages than those agencies relying primarily on surface water, due to the limited influence of climatic variability on groundwater supplies. Nevertheless, it is still important for groundwater agencies to reduce production during drought years to avoid excessive overdraft of the groundwater basin. VWDs rationing plan will be invoked during declared water shortages. Each stage includes a water reduction objective expressed as a percentage of normal demands. The rationing plan is dependent on the cause, severity, and anticipated duration of the water supply shortage. Stage 1: Normal Water Supply Condition (Year-Round Water Conservation) Stage 1 (when VWD is able to meet all the water demands of its customers in the immediate future) shall be in effect at all times, unless the City Council otherwise declares under the provisions of Section 10.05.070 of VWD Ordinance No. VWD012 that one or more of the VWDs stages are in effect. During Conservation Stage 1, it shall be unlawful and a violation of VWD Ordinance No. VWD012 for any water user to make, cause, use, or permit the use of water in any manner contrary to the provisions of the prohibitions listed in Table 1-3. The VWDs Ordinance No VWD-012 is available in Attachment 2. Stage 2: Threatened Water Supply Shortage Stage 2 shall be in effect when VWDs ability to provide water for ordinary domestic and commercial uses may be adversely impaired or threatened. Shortage Stage 2 will be implemented when a 10% to 28% reduction in total potable water production or water usage must be met. The actual percentage reduction required (based on State conservation mandates and other contributing factors) will be indicated in the VWD resolution enacting Shortage Stage 2. During Shortage Stage 2, it shall be unlawful and a violation of VWD Ordinance No. VWD012 for any water user to make, cause, use, or permit the use of water in any manner contrary to the prohibitions listed in Table 1-3. Stage 3: Critical Water Supply Shortage Stage 3 shall be in effect when VWDs ability to provide water for ordinary domestic and commercial uses may be critically impaired or threatened. Shortage Stage 3 will be implemented when a 29% to 40% reduction in total potable water production or water usage must be met. The actual percentage reduction required (based on State conservation mandates and other contributing factors) will be indicated in the VWD resolution enacting Shortage Stage 3. During Shortage Stage 3, it shall be unlawful and a violation of VWD Ordinance No. VWD012 for any water user to make, cause, use, or permit the use of water in any manner contrary to the prohibitions listed in Table 1-3. Stage 4: Emergency Water Supply Shortage Stage 4 shall be in effect when a disaster or other major disruption in the water supply or any emergency that prevents VWD from meeting the water demands of water users is threatened or exists. Shortage Stage 4 will be implemented when a total potable water production or water usage reduction in excess of 41%. The actual percentage reduction required (based on State conservation mandates and other contributing factors) will be indicated in the VWD resolution enacting Shortage Stage 4. Prohibitions during stage 4 are provided in Table 1-3.
Victorville Water District 1-6 Water Shortage Contingency Plan The City Manager shall promulgate a drought management plan containing regulations setting forth the criteria for implementation and termination of various water use reduction stages. The City Manager is authorized to declare a water shortage, and to implement a water shortage management plan, in response to events including (but not limited to) reductions in supply from any water purveyor or when an insufficient supply appears likely due to water system limitations or structural failure. Such declaration may designate the entire area of the City or a portion of it if the shortage is not citywide. The CWC outlines six standard water shortage levels that correspond to a gap in supply compared to normal year availability. The six standard water shortage levels correspond to progressively increasing estimated shortage conditions (up to 10%, 20%, 30%, 40%, 50%, and greater than 50% shortage compared to the normal reliability condition) and align with the response actions that a water supplier would implement to meet the severity of the impending shortages. The CWC allows suppliers with an existing water shortage contingency plan that uses different water shortage levels to comply with the six standard levels by developing and including a cross-reference relating its existing shortage categories to the six standard water shortage levels. VWD is maintaining the current four shortage stages for this WSCP. A crosswalk defines how VWDs current water shortage stages will align with the DWRs standardized six levels of shortage. A visual representation of this alignment is shown in Figure 1-1. Table 1-2 summarizes DWRs WSCP levels and where VWDs levels align. Figure 1-1. Crosswalk to DWRs Six Shortage Stages Table 1-2.

1.4 Shortage Response Actions This section was completed pursuant to CWC Section 10632(a)(4) and 10632.5(a) and describes the response actions that must be implemented or considered for each stage to minimize social and economic impacts to the community. 1.4.1 Demand Reduction Mandatory compliance measures enacted during a water shortage are more severe than voluntary measures, produce greater savings, and are less costly to the utility. The principal drawback to these measures could result from customer resentment if the measures are not seen as equitable. Therefore, such measures need to be accompanied by a good public relations campaign. The demand reduction actions for each stage are shown in Table 1-3.
Victorville Water District 1-10 Water Shortage Contingency Plan
1.4.2 Supply Augmentation Table 1-4 identifies the supply augmentation actions VWD can take in the event of a water shortage condition. VWD currently maintains interconnections with Mojave Water Agency. During water shortage emergencies, VWD may be able to obtain supplemental water supply though this connection, if available. Table 1-4. Supply Augmentation & Other Actions DWR Table 8-3 SHORTAGE LEVEL SUPPLY AUGMENTATION METHODS AND OTHER ACTIONS BY WATER SUPPLIER HOW MUCH IS THIS GOING TO REDUCE THE SHORTAGE GAP? ADDITIONAL EXPLANATION OR REFERENCE 4 Other purchases 0-15% Purchase additional water from Mojave Water Agency if available 1.4.3 Emergency Response Plan In 2025, VWD completed a Risk and Resilience Assessment (RRA) and Emergency Response Plan (ERP) in accordance with Americas Water Infrastructure Act (AWIA) of 2018. The purpose of the RRA and ERP is to meet the AWIA compliance requirements and plan for long-term resilience of VWDs infrastructure. The RRA assessed VWDs water system to identify critical assets and processes that may be vulnerable to human and natural hazards, and to identify measures that can be taken to reduce risk and enhance resilience from service disruption for the benefit of customers. The RRA identifies and characterizes both infrastructure-specific and system-wide vulnerabilities and threats and quantifies the consequences of disruption. The RRA also identifies various options (and constraints) in addressing and mitigating risk. The RRA, in conjunction with the ERP, charts a course for water system resilience. The RRA also provided various recommendations to increase reliability of VWDs system. Because critical pieces of infrastructure and specific vulnerabilities are detailed in the RRA and ERP, the contents of the document are confidential and for use by VWDs staff only. However, VWD can confirm that these plans meet the requirements set forth by AWIA and evaluate seismic risks and mitigation actions to VWDs infrastructure. In the event of a water shortage emergency resulting from equipment failure, power outage, or other catastrophe, VWD is prepared to purchase emergency water supplies from nearby agencies while repairs or other remedial actions are underway. VWD may also implement its four-stage plan for conservation, as described above, with either voluntary or mandatory reductions depending on the severity of the shortage. For severe disasters (Stage 4), mandatory water use reductions are specified. 1.4.4 Seismic Risk Assessment and Mitigation Plan Disasters, such as earthquakes, can and will occur without notice. VWD has assessed the risk and mitigations for water facilities. VWD has identified a set of hazard mitigation actions that are intended to reduce the impact of hazards, including: Installed isolation valves on main transmission lines. Replaced pipes in areas of moderate to high liquefaction or traverse active faults. Strengthened concrete tank walls on large reservoirs. Retrofitted water tanks. Installed well discharge piping to accommodate differential settlement. Installed flexible connections for pipeline connections to pump stations.

1.4.5 Shortage Response Action Effectiveness VWD has estimated the effectiveness of shortage response actions when data pertaining to such actions is available. Estimates of the effectiveness for actions has been included in the DWR submittal tables. It is expected that response actions effectiveness is also a result of successful communication and outreach efforts. 1.5 Communication Protocols VWD prioritizes effective communication, especially in times of a water shortage emergency. VWD routinely communicates to customers about details on when a stage is announced. Communication actions may include bill inserts, handouts, informative flyers, and direct mail pieces to newspaper and bus shelter advertisements, news releases, social media outreach, and website content. VWD continues to provide reminders about shortage levels and encourages conservation at all times. 1.6 Compliance and Enforcement Section 10 of VWDs Ordinance No. VWD012, sets forth the fourstage WSCP, where violations to all mandatory provisions are a misdemeanor and violators may be punished by imprisonment, fine or both. In addition to these criminal penalties, the following civil actions can be initiated by VWD: For a first violation of any provision of the WSCP, the enforcement officer shall issue a written notice of first violation and provide the violator with educational materials on landscape water conservation, including a copy of this chapter. The notice shall give the designated water user a reasonable period of time to correct the violation. Failure to correct the violation within a reasonable period of time shall constitute a second violation. For a second violation of any provision of this chapter, the City shall issue a written notice of second violation to the designated water user imposing a fine in an amount not to exceed $100 and requiring immediate correction of the violation. For a third violation of any provision of this section, the City shall issue a written notice of third violation to the designated water user imposing a fine in an amount not to exceed $200 and requiring immediate correction of the violation. For a fourth or subsequent violation of this section, the City shall impose a fine in an amount not to exceed $500. The fourth and each subsequent violation of this chapter shall be deemed a public nuisance, which may be abated pursuant to the procedures provided in Chapter 13.02 nuisances of the Citys Municipal Code (Citys Code). Any citations issued and fines imposed on designated water users for violations of the chapter shall be served, administered, collected, and appealed in accordance with the procedures of Chapter 1.05 administrative remedies of the Citys Code. 1.7 Legal Authorities The Citys Code Chapter 13.60 addresses water conservation and establishes water waste prohibitions. This section of the Citys Code is adopted through Ordinances 2114, 2133, 2135, and 2338. City Ordinance No. 2338, revised Chapter 13.60 of the Citys Code to include provisions for water efficient landscaping as well as restrictions and prohibitions related to water waste. VWD also has adopted Ordinance Number VWD012 on May 19, 2015, which adopts a conservation program and amends the VWDs WSCP.

1.8 Financial Consequences of WSCP In May of 2021, VWD updated its comprehensive water rate study from 2015 for several reasons, including meeting longterm revenue requirements, providing revenue stability and adequate funding for capital improvements, and complying with legal requirements, including Proposition 218. The rates proposed in this study were developed in a manner that is consistent with industry standards, including court rulings affecting how the cost bases for water rates should be established. The rate study specifically addressed several key issues, including: Revenue Requirements and Financial Planning The long-range financial plan for VWD was closely examined and adjusted to best meet annual operating expenses, capital improvement costs, annual other post-employment benefits funding requirements, and established reserve requirements. Rate Structure rate structure was evaluated to ensure it is consistent with industry standards and addresses other key objectives. The fixed monthly charge will continue to be based on meter size which provides greater revenue stability. VWD also compared a number of volumetric rate alternatives, including tiered and uniform volumetric alternatives. Given source of supply and costs, the proposed 2-Tier volumetric rates for single-family residential customers with a uniform volumetric rate for all other customers is best suited for VWD. Fixed vs. Variable Charges The amount of revenue collected from fixed charges vs. volumetric rates was carefully examined. The proposed rate design will collect the projected water supply costs from volumetric charges and the remaining revenue requirement from fixed charges. In the first year of the rate adjustment, new rates will continue to collect 27% of revenue from fixed charges and 73% from volumetric charges but will transition to a 40% fixed and 60% volumetric split by Year 5 of the proposed rates to move closer to the 53% fixed and 47% volumetric split that resulted from the cost-of-service analysis. By adjusting the fixed vs. volumetric split, VWD is increasing revenue stability while still promoting conservation. Statewide Conservation The State imposed drought-related conservation level 2 (25% Statewide) back in 2015 and VWD was mandated to reduce water consumption by 28% beginning in April 2015. As the State may be heading into another drought, the current and projected future consumption levels were closely evaluated and incorporated into the rate study. LongTerm Conservation The assumptions and recommendations contained in the rate study assume that water supplies will continue to be limited in the future and that, in the long run, customers will reduce consumption accordingly. Therefore, the drought rates developed in the rate study will allow VWD to meet its annual revenue requirements at various stages of conservation even if drought conditions worsen over the next five years. The new volumetric rate structure recommended by the rate study is set to the marginal cost of water, meaning that changes in consumption would cause matching changes in revenue and expenses. Under this structure, a reduction in water sales due to conservation would not have a negative fiscal impact on VWD. Drought rates can be implemented by VWD at various conservation levels that range from 20% through 50%; however, due to the higher marginal cost savings provided by the new rate structure, drought rates would not be needed after Year 2 since the losses from drought revenue reductions would be offset by marginal cost reductions. Drought rates were developed in 10% increments that VWD can implement for 20% through 50% conservation levels. The new rates are subject to the substantive and procedural requirements of Proposition 218 (Cal. Const. Art. XIIID). Section 6 of Article XIIID sets forth standards for setting rates that reflect the proportional cost of providing water services, as well as requirements for providing notice, a public hearing, and the ability to protest such proposed revisions to and increases in charges and fees for water service.
Victorville Water District 1-13 Water Shortage Contingency Plan To ensure VWD customers comply with Ordinance 225 and CWC Chapter 3.3 (Excessive Residential Water Use During Drought), additional staff costs will be incurred to monitor and enforce response actions. The incurred cost may vary depending on the shortage stage and duration of the water shortage emergency. 1.9 Monitoring and Reporting The water savings from implementation of the WSCP will be determined based on monthly production reports, which are reviewed and compared to production reports and pumping statistics from prior months and the same period of the prior year. Under shortage conditions, these production reports could be prepared as often as daily. At first, the cumulative consumption for the various sectors (e.g., residential, commercial, etc.) will be evaluated for reaching the target level. Then if needed, individual accounts will be monitored. Weather and other possible influences may be accounted for in the evaluation. 1.10 WSCP Refinement Procedures The WSCP is best prepared and implemented as an adaptive management plan. VWD will use results obtained from their monitoring and reporting program to evaluate any needs for revisions. Potential changes to the WSCP that would warrant an update include, but are not limited to, any changes to trigger conditions, changes to the shortage stage structure, and/or changes to customer reduction actions. Any prospective changes to the WSCP would need to be presented to City Council for discretionary approval. Once discretionary approval has been granted, VWD will hold a public hearing, obtain any comments and adopt the updated WSCP. Notices for refinement and the public hearing date will be published in the local newspaper in advance of any public meetings. 1.11 Plan Adoption, Submittal, and Availability VWD adopted this WSCP with the 2025 RUWMP. The 2025 RUWMP and WSCP were made available for public review in June 2026 and a public hearing was held on June 16, 2026 to receive public input on the draft 2025 RUWMP and the WSCP. The City Council adopted the 2025 RUWMP and the WSCP at a public meeting on June 16, 2026. The resolution of adoption is included in Attachment 1. This WSCP was submitted to DWR through the WUEdata portal before the deadline of July 1, 2026. This WSCP will be available to the public on the Citys web site. If VWD identifies the need to amend this WSCP, it will follow the same procedures for notification to cities, counties and the public as used for the 2025 RUWMP and for initial adoption of the WSCP.

Many factors determine whether a Water-wise Plant will adapt or perform well, and even though a plant appears on the WWP List, there is no assurance it will adapt or thrive. Therefore, from time to time, the General Manager or his/her designee will amend the WWP List as necessary to add or remove plants. The Water-wise plant list is a tool for use whether designing a new landscape or converting from traditional turf to a desert wise water efficient landscape. The plant canopy coverage is derived mathematically by multiplying the mature diameter of the plant by a formula to provide the square footage number. Determining the mature width of plants can be tricky. It may take many years or even decades for a plant to reach its ultimate width.
