subdivisions; assured water supply; lots

SB 1598 requires developers to obtain a certificate of assured water supply or a written commitment from a designated city, town, or private water company before selling or leasing subdivided lots in Arizona's active management areas. This applies to all new subdivisions where plat approval is needed or land is offered for sale/lease, ensuring water availability for future residents. The bill exempts mineral extraction developments and properties already served by designated water providers, while directing the water director to designate qualifying entities and update rules for gray water systems. It directly affects land developers, local governments approving plats, and water providers in water-scarce regions.
