assured water supply; commingling

This bill establishes a requirement for developers in Arizona's active management areas to secure a certificate of assured water supply or a written commitment from a designated water provider before selling subdivided land. It empowers local governments and the state real estate commissioner to approve subdivisions or issue public reports only when these water supply guarantees are in place, ensuring new developments have reliable access to water. The legislation designates specific cities, towns, and private water companies as having an assured water supply, particularly those with existing contracts for Central Arizona Project water, while exempting industrial and mineral extraction projects from these rules. Additionally, the bill mandates that the state director notify local officials of designated water providers and allows for reduced water demand calculations if developers install gray water reuse systems.
