The proposed bill would update current groundwater management statutes in Arizona by introducing new provisions that allow landowners in the Phoenix and Pinal active management areas (AMAs) to apply for groundwater savings credits through the permanent relinquishment of their irrigation grandfathered rights (IGFR). Key updates include conditions for exempting certain volumes of groundwater from demonstrating physical availability, and requirements for the Director of the Arizona Department of Water Resources (ADWR) to identify the amount of groundwater savings credits issued. The bill also mandates that by December 31, 2033, the Director must assess the feasibility of extending the groundwater savings program for each AMA and allows for the pledging of these credits in assured water supply applications. Additionally, the bill prohibits municipalities from imposing specific landscaping requirements in subdivisions where groundwater savings credits have been pledged, and establishes a program for administering groundwater savings credits by December 31, 2035. It clarifies that municipalities cannot increase lot sizes or reduce lot yields once zoning is approved, nor can they require applicants to procure water that the municipality is obligated to pledge. Overall, these updates aim to enhance water conservation efforts, provide clarity for municipalities and landowners, and ensure sustainable groundwater management practices in Arizona.
