AZ SB1515

Amends Arizona Revised Statutes Section 11-823 to require counties outside active management areas to adopt provisions ensuring adequate water supplies for subdivisions, with board approval by unanimous vote.

Allows counties to exempt subdivisions with inadequate water supplies if water is transported by motor vehicle or train, provided the board determines no feasible alternative exists and transportation poses no significant health/safety risk.

Requires counties not in active management areas to review the adequate water supply provision at least every ten years, with option to discontinue it by unanimous board vote if specific conditions are met regarding aquifer recharge, reclaimed water plans, water conservation programs, and other water management measures.

Mandates counties note on subdivision plats whether adequate water supply has been determined or committed, or if an exemption applies; requires written notice to state water resources, environmental quality, and real estate officials.

Exempts subdivisions that received final plat approval before the water supply requirement became effective, provided the plat has not been materially changed.
