SUBJECT:
Resolution Accepting the District’s 2025 Urban Water Management Plan (UWMP) for the Planning Period 2025-2045
RECOMMENDED ACTION
It is recommended that the Board of Directors of the Hesperia Water District (District) adopt Resolution No. HWD 2026-07 accepting the District’s 2025 Urban Water Management Plan (UWMP), as written or as amended during the public hearing, and authorize submittal of the UWMP to the California Department of Water Resources as required by the Urban Water Management Planning Act.
BACKGROUND
Per California’s Urban Water Management Planning Act (Act), every water supplier must prepare and adopt an UWMP every five years for submittal to the California Department of Water Resources (DWR). The Act requires water agencies to prepare a plan that provides water supply planning over a 20-year period in five-year increments. The UWMP is a planning tool that provides the City and the public with a broad perspective on water supply issues and is required for the District to be considered for future grant funding opportunities or to receive drought assistance from the State.
The UWMP must describe the adequacy and reliability of all water supplies for existing and future customers. The intent of the UWMP is to provide assistance to water purveyors in carrying out their long-term resource planning responsibilities to ensure that there are adequate water supplies to meet existing and future demands for water. The UWMP must identify and quantify current and future water supplies, including recycled water and desalination, for existing and future demands in normal, single-dry and multiple-dry years and is to describe conservation program implementation and efficient use of urban water supplies.
ISSUES/ANALYSIS
In November 2025, the Mojave Water Agency convened a workshop for all water purveyors within its service area required to prepare an Urban Water Management Plan (UWMP). The workshop included participation from Zanjero (formerly Tully & Young), which previously completed the District’s two most recent UWMPs.
The purpose of the workshop was to assess interest in a collaborative approach with the Mojave Water Agency to develop a Regional Urban Water Management Plan (RUWMP). Following this discussion, staff elected to participate in the regional effort based on several considerations, including Zanjero’s established familiarity with the District and the Mojave River Valley, as well as anticipated cost savings of approximately $10,000. Of the twelve agencies invited to participate, ten elected to join the regional effort.
The California Water Code requires that wholesale and retail water providers, of at least 3,000 acre-feet of water sales or with 3,000 or more retail connections, prepare and submit an UWMP update every five years. Submittal of the adopted UWMP is critical for water management planning efforts and maintains the City’s eligibility for water grants or loans administered by the DWR.
The process for developing this plan was extensive. Staff and Zanjero, Inc. coordinated on developing the methodology to be utilized within the plan. District staff attended in-person workshops and virtual meetings with the consultant to ensure all data was correct, agreed to, and acceptable. During these meetings staff and the consultant discussed the methodology and approach to compiling the data for the plan. This data was then formulated and presented as a complete service area demand. This effort included a strong emphasis on coordination with neighboring water suppliers and the Mojave Water Agency. The Draft 2025 UWMP was completed and made available for review in May 2025.
Staff is recommending that the Board of Directors adopt the Public Draft 2025 UWMP as written or as amended during the public hearing as the Hesperia Water District 2025 Urban Water Management Plan and authorize staff to submit the plan to the DWR.
CITY GOAL SUPPORTED BY THIS ITEM
Public Safety - Ensure public safety resources adequately protect our community.
Financial Health - Maintain a balanced budget and adequate reserves.
FISCAL IMPACT
The District entered into an agreement with the Mojave Water Agency in the amount of $15,000, who is responsible for managing the contract with Zanjero to assist staff with the preparation of the 2025 UWMP. After the adoption of the plan by the Board and submittal to the DWR, no further expenditures will be necessary.
There is no fiscal impact associated with adoption of the 2025 UWMP. Water suppliers that do not complete an updated UWMP are not eligible to apply for state or federal water grants.
