assured water supply; building permits

SB 1530 requires developers to obtain a "certificate of assured water supply" from Arizona's director or a written water service commitment from a designated city, town, or private water company before selling or leasing subdivided land, or before approving building permits for residential, commercial, or industrial development in active water management areas. This applies to all new subdivisions and land sales in designated areas, exempting only mineral extraction projects. The bill establishes a process for the director to designate qualifying water providers and allows developers to reduce water demand requirements by installing approved gray water systems. It directly affects developers, local governments approving plats or permits, and water providers in Arizona's active management areas.
