Water infrastructure rules governing stormwater management in the Great Salt Lake basin would change under this bill, which covers a large watershed area including the drainages of the Bear River, Bear Lake, Weber River, Jordan River, Utah Lake, and Tooele Valley. Starting January 1, 2027, cities and counties that hold stormwater permits (permittees) would be required to prioritize infiltration or reuse methods over the use of retention basins — structures designed to hold stormwater to reduce flooding and improve water quality — unless the person seeking to develop the land shows no feasible alternative exists. When a detention basin is required instead — a structure that temporarily captures and slowly releases stormwater — it would need to be designed to drain all of its stored water, as long as doing so does not interfere with flood control or the capacity of the drainage system. The bill also adds formal legal definitions for terms such as "detention basin," "retention basin," and "Great Salt Lake basin" to the state's stormwater permitting law, and makes minor wording and organizational changes elsewhere in that law.
