This bill proposes to update current statutes by appropriating $100,000 from the state General Fund for fiscal year 2027 to the Arizona Department of Water Resources (ADWR) for the purpose of creating an updated stormwater recharge mapping. The bill mandates that within one year of its effective date, ADWR must produce a map of potential stormwater recharge sites that do not capture appropriable surface water and do not conflict with vested rights.

Additionally, the bill specifies that the updated map must identify recharge sites based on certain criteria, including their location on any land (public or private), optimal soil conditions for stormwater infiltration and groundwater recharge, and the stipulation that development of these sites would not appropriate surface water. Furthermore, the bill defines "stormwater" as unappropriated rainwater runoff that does not enter a stream or natural channel or is otherwise lost to evaporation.
