AZ HB2553

Amends Arizona Revised Statutes section 11-823 regarding county regulations on water supply adequacy for subdivisions located outside active management areas.

Adds a periodic review requirement for counties not in an active management area to reconsider their water supply adequacy provisions within 5 years of the amendment's effective date and at least every 10 years thereafter.

Allows counties to discontinue their water supply adequacy requirements if they unanimously vote not to readopt the provision AND meet eight specific conditions including aquifer recharge programs, reclaimed water plans, water conservation programs, xeriscape ordinances, plumbing fixture rebate programs, water loss limits, and public education initiatives.

Maintains existing notification requirements to state water resource officials and clarifies plat notation requirements when water supply is adequate, committed, or inadequate.
