irrigation water; assured water supply

SB 1304 allows Arizona cities or towns to apply for an "assured water supply" designation for specific areas within their boundaries. To qualify, applicants must prove they are located within an irrigation district, have a 100-year water contract with that district for municipal irrigation use, guarantee 100 years of continuous water availability, and demonstrate financial capability to build required infrastructure. The bill directly affects cities/towns seeking long-term water security and irrigation districts providing water under these contracts. It establishes clear, measurable criteria for the state director to review and approve such designations, focusing on water reliability and financial planning.
