Requirement of Arizona's Departments of Water Resources (ADWR) and Real Estate (ADRE) that developers (subdividers) demonstrate that an assured or adequate water supply will be physically, legally, and continuously available for the next 100 years in new subdivisions. If the subdivision is located within one of ADWR's Active Management Areas (AMA), a public report will not be issued and lots may not be sold until an assured 100-year water supply is demonstrated. Outside of AMA's, developers are required to ask ADWR for an assessment of the availability of water. In these areas, lots may still be sold even if ADWR deems the water supply inadequate, as long as this information is disclosed to prospective buyers.
