HB 2572 Arizona House · 57th Legislature - First Regular Session

technical correction; groundwater rights; AMAs

HB 2572 amends Arizona's subdivision regulations to clarify water supply requirements for developments in Active Management Areas (AMAs). It requires municipalities to verify that subdivisions within AMAs include a "certificate of assured water supply" from the Director of Water Resources, or a written commitment from a designated water provider, before approving final plats. This directly affects developers and municipalities handling new subdivisions in designated water management zones. The bill makes technical corrections to existing law (ARS § 9-463.01) to ensure consistent implementation of water supply rules, without changing the underlying policy. The bill passed the legislature in April 2025 but was vetoed by the Governor on May 2.

MODERATE
This bill expands groundwater protections by clarifying that new development in 'subsequent active management areas' requires adequate water supply commitments, similar to existing rules in 'initial' areas. It also updates procedures for subdividing land, adding water supply requirements for timeshare developments and clarifying rules for irrigation rights in subsequent management areas.
Scope change
The bill extends water supply adequacy requirements to subsequent active management areas (previously only initial areas were covered) and adds specific provisions for timeshare developments and irrigation right transfers.
REQUIREMENT

Added water supply adequacy requirements for subdivisions in subsequent active management areas, requiring developers to demonstrate sufficient water for 100 years or obtain written commitments from water providers.

Added new sections allowing owners of irrigation grandfathered rights in subsequent active management areas to add, substitute, convey, or combine acres within the same groundwater basin.

Added water supply disclosure requirements for timeshare developments in subsequent active management areas.

DEFINITION

Updated references to clarify that subsequent active management areas are subject to the same water supply adequacy standards as initial active management areas.

TECHNICAL

Corrected formatting and citation errors throughout the bill text, including statute section numbers and cross-references.
