Notice of Intent to Prepare a Regional Urban Water Management Plan for the Mojave Region

This notice is to inform you that the urban water suppliers within the greater Mojave region are preparing a 2025 Regional Urban Water Management Plan (UWMP) pursuant to the California Water Code (CWC). All wholesale and retail urban water suppliers serving more than 3,000 customer connections are required to prepare an UWMP every five (5) years. The following urban water suppliers are collectively preparing this Regional UWMP:

• City of Adelanto Water District
• County Service Area 64
• County Service Area 70J
• Helendale Community Services District
• Hesperia Water District
• Hi-Desert Water District
• Golden State Water Company - Barstow System
• Joshua Basin Water District
• Liberty Utilities - Apple Valley Water Company
• Mojave Water Agency
• Phelan Piñon Hills Community Services District
• Victorville Water District

The purpose of a Regional UWMP is to allow the urban water suppliers to coordinate and efficiently address the State's requirements as mandated in the CWC through a regional representation of water supply reliability. While the Regional UWMP will provide overarching and consistent information on water supplier reliability, each urban retail supplier will also update its unique Water Shortage Contingency Plan (WSCP), tailored to its specific service area and operations. Each urban supplier will separately adopt the Regional UWMP and its unique WSCP by July 1, 2026.

In accordance with CWC Section 10642, which encourages "active involvement of diverse social, cultural, and economic elements of the populations" in preparing a UWMP, the public will, at a minimum, have the opportunity to participate in the planning process through public hearings anticipated to occur in April or May of 2026 as part of each urban supplier's adoption process. A draft copy of the 2025 Regional UWMP will be made available for review prior to hearings, providing an opportunity for (1) Community input regarding water supply reliability; (2) Consideration of the economic impacts of complying with CWC status governing the Regional UWMP; and (3) Discussion of each agency's WSCP.

Detailed information, including contacts for each agency, future public hearing notices, schedules, and draft plan materials, will be available at the Mojave Water Agency's website at https://www.mojavewater.org/basin-management/regional-planning/urban-water-management-plan/ or at similar links hosted by each urban retail water supplier.

Questions regarding this notice or the 2025 Regional UWMP process may be directed to the appropriate retail agency using the contact information found on the website.
