Before a developer can record plats of land or sell parcels in certain areas, they must show Arizona real estate officials that the water supply is assured for 100 years.
The state Department of Water Resources says it's holding a series of informal meetings on a possible new way to satisfy the requirement.
Officials say an alternative path to a 100-year-assured-water-supply designation aims to address challenges faced in pursuing the classification.
Proposed language says stored water from outside the impact area would be considered available to an applicant seeking a designation.
The assured-supply requirement applies to areas in five counties that are actively managed by the state due to major groundwater reduction.
The first meeting is scheduled for April 22. State officials will present information on draft rules and take comments.
