rural groundwater management areas; establishment.

SB 1425 amends Arizona law to require proof of adequate water supply for new subdivisions in rural groundwater management areas before county boards can approve final plats. It directly affects subdividers, counties, and water providers by mandating either a written commitment from a designated water supplier or a director’s determination of adequate water supply. Key provisions include establishing a specific exemption process for transporting water via vehicle/train (if safety and feasibility conditions are met) and requiring counties to document water adequacy status on subdivision plats. The bill does not create new groundwater management areas but implements water supply requirements for existing rural areas, focusing on concrete approval standards for land development.
