Cisco, Utah Townsite

The foundational threat to Cisco's historic townsite is a water rights change application filed by the San Juan Water Conservancy District on July 1, 2025. This application seeks to convert Water Right 91-5233, originally allocated in 1958 for a nuclear power plant that was never constructed, from power generation to municipal use. Approval would permit diverting up to 24,000 acre-feet per year from the Colorado River near Cisco. The outcome of this water rights decision will determine the feasibility of all subsequent development threats. Without water, development cannot proceed. The Utah Division of Water Rights is currently reviewing the application, and no decision has been issued. Two formal protests were filed, and a public hearing took place on October 14, 2025, in Green River.

If the water rights change is approved, it would enable a proposed 750-lot residential development by Havilah Homes Inc., led by developer and attorney Lawrence Hilton and marketed as "Cisco Disco." This development would subsequently require Grand County planning and zoning approvals, National Environmental Policy Act (NEPA) review, and substantial infrastructure investment, a process likely to extend over several years. The developer has stated that formal county-level discussions have not yet commenced and that coordination with regulators will begin only after initial engineering is complete and the water right is secured.

The principal threat to Cisco's historic character is not the immediate demolition of specific structures, but rather a sequence of events initiated by the water rights decision. Approval would establish the legal and financial framework for the development of 750 lots, a scale that would fundamentally alter Cisco's historic fabric, vernacular architecture, and the artist community that has actively stewarded the townsite over the past decade. Each subsequent step in the approval process following a water rights decision increases the difficulty of halting further development.
