HB 2091 Arizona House · 57th Legislature - First Regular Session

land division; applicant submissions; review

HB 2091 allows the Arizona Department of Water Resources to review pending applications for a "certificate of assured water supply" for land in the Phoenix Active Management Area (AMA) submitted between January 2021 and August 2023. It requires municipal water providers to annually report excess groundwater and offer 25% of it as water storage credits to the Central Arizona Groundwater Replenishment District (CAGRD), reducing their annual replenishment tax obligation. The bill also permits applications using older groundwater models (2006-2009) to meet physical availability requirements and retroactively dates approved certificates to 2023 for future water rights. The law expires on December 31, 2028.
