assured water supply; analysis; availability

SB 1288 modifies Arizona's process for issuing "certificates of assured water supply" needed for development projects. It allows the director to accept groundwater analyses or availability determinations made before May 31, 2023, as valid proof of water supply, after adjusting for existing certificates. Developers applying for these certificates must submit a sworn statement agreeing to reduce the reserved groundwater volume by 15% after approval. The bill ensures consistency by requiring certificates to use the same water usage estimates in place when the original analysis was issued, directly affecting developers and water providers managing groundwater rights.
