AZ HB2397

Changes county board of supervisors requirement to adopt water adequacy provisions from discretionary ("may") to mandatory ("shall") under section 11-823, making the water supply adequacy requirement statewide applicable outside active management areas.

Modifies water adequacy requirement language across multiple sections to apply uniformly statewide, eliminating previous distinctions between counties that had or had not adopted the provision.

Updates references in real estate subdivision statutes (sections 32-2181, 32-2183, 32-2197.08) to reflect the mandatory statewide water adequacy standard for subdivision platting and public reports.

Clarifies that exemptions from adequate water supply requirements may be granted by the director of water resources under sections 45-108.02 and 45-108.03 for subdivisions meeting specific criteria related to capital investment or future water availability.

Makes conforming changes to section 45-108 and related provisions to establish consistent water supply evaluation procedures and definitions of "adequate water supply" applicable across the state.
