House passes 40‑year water planning proposal after debate on developer responsibilities

The Utah House approved Second Substitute House Bill 439 on Tuesday, a measure sponsors described as a step to ensure long‑term water planning as development continues.

Representative Shallenberger, the bill sponsor, told the chamber the bill directs the state water engineer to create a 40‑year planning template so cities, special districts and counties have a standard to show water availability for new developments or pursue exactions where needed. "As we've worked with different cities, special districts, municipalities, counties, we are looking and trying to plan for water in the future," the sponsor said on the floor.

Representative Peck questioned whether the bill would shift the onus for securing water rights onto cities and counties and warned it could produce disputes between developers and local governments. "I have a concern that we're gonna put all of the onus for water for developments on the cities and counties," Peck said. Sponsor Shallenberger responded that the bill "brings all parties to the table" and helps communities plan for future growth.

Supporters argued the measure adds consistency and encourages municipalities and water districts to coordinate long‑range planning; opponents expressed concern about potential allocation conflicts and the effect on developers. The bill passed 59–8 and will be transmitted to the Senate for its consideration.

Next steps: the Senate will consider the bill and any amendments; implementation details (the engineer's template and guidance) will be developed administratively if the bill becomes law.
