rural groundwater management areas; establishment.

SB 1742 establishes "rural groundwater management areas" in Arizona, requiring new subdivisions in these areas to prove adequate water supply before approval. It directly affects developers and local governments building housing in rural regions relying on groundwater, mandating either a water adequacy report from the state director or a written commitment from a designated water provider. Key provisions include strict conditions for exemptions (like water transported by vehicle/train) and require counties to report approvals to state agencies. The bill does not change existing water rights but adds a layer of review for new developments outside designated groundwater management zones.
