assured water supply; agricultural water

SB 1260 amends Arizona law to establish clearer criteria for cities and towns to qualify for an "assured water supply" designation within specific areas. It directly affects municipalities seeking long-term water access by requiring them to: (1) contract with agricultural water providers or irrigation districts for at least 100 years, (2) prove continuous surface water or treated wastewater availability for 100 years, and (3) demonstrate financial capability to build necessary infrastructure. The bill specifies that only areas within the Phoenix active management zone and exempted regions under existing law qualify for this designation. This change aims to formalize how agricultural water sources can be legally designated for municipal use in Arizona's water-scarce regions.
