AZ SB1369

Amends Arizona water adequacy laws to make water supply requirements mandatory statewide for subdivisions outside active management areas, changing language from "may" to "shall" require adequate water supply determinations before plat approval.

Modifies county board of supervisors authority to adopt water adequacy provisions under section 11-823, eliminating the requirement for unanimous board vote and making adoption mandatory rather than discretionary.

Extends water adequacy evaluation requirements to apply uniformly across all counties and cities/towns, regardless of whether they have individually adopted such provisions, by referencing sections 9-463.01 and 11-823.

Updates terminology throughout related statutes (sections 32-2181, 32-2183, 32-2197.08, 45-108, 45-108.01, 45-108.02, and 45-108.03) to reflect mandatory application of water supply adequacy standards and clarifies procedures for exemptions and designations.

Maintains existing exemptions for subdivisions with substantial capital investment, adequate water supply commitments from designated providers, or approval under specified exemption criteria, with clarified procedures for director approval and public notice requirements.
