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.

Administered by the Arizona Department of Water Resources (ADWR), the state's Active Management Areas (AMA's) were established to provide long-term management and conservation of limited groundwater supplies. The five (5) AMA's - Prescott, Phoenix, Pinal, Tucson, and Santa Cruz - cover the majority of Arizona's agricultural land and urban population centers that exist where groundwater supplies are extremely limited. Rules governing water use and land development in AMA's are generally more stringent and focused on conservation of water resources in than elsewhere in the state. Applications for new development and subdivisions are managed by ADWR's Office of Assured and Adequate Water Supply under the Assured Water Supply Program.

This program operates outside Active Management Areas (AMA's) in the state of Arizona to address water availability in new subdivisions. Developers or subdividers are required to request a water supply assessment for the next 100 years from the Arizona Department of Water Resources (ADWR). If the 100-year water supply is deemed inadequate, lots may be sold only if the developer clearly discloses this fact to potential buyers.

1. Zoning ordinances that specify certain types of architecture to encourage pleasing or beautiful building appearances. 2. Zoning ordinances that regulate uniformity of architecture, so that new construction is similar to and in scale with existing structures.

Zoning policies intended to protect farmland and farming activities from incompatible nonfarm uses, such as residential and commercial development. Agricultural protection zoning, aslo referred to as agricultural zoning, can specify many factors, such as preferred land use, minimum size of farm or the number of nonfarm or residential dwellings allowed. Agricultural zoning is usually based on historic land use, soil properties, and location and allows activities such as orchards, farms, ranching, or timber production.

Title to real property that is free of encumbrances and obligations, including taxation. It denotes absolute or supreme ownership. Strictly defined, allodial title is not subject to county, state, or federal codes, ordinances, or zoning regulations ("police power"), nor can it be taken through legal or regulatory means ("inalienable"). In practical use, title in the United States is often said to be allodial (as opposed to feudal), even though it does not meet all of the qualifications listed above.

The Department of Water Resources is Arizona's state water management agency. Created during enactment of the Groundwater Management Code (1980), the department is charged with securing long-term water supplies for communities within the State of Arizona. Principal duties of ADWR include implementation of the Groundwater Management Code, registration of all surface and groundwater rights, ensuring the safety of non-federal dams, assisting with local management of floodplains, and representing Arizona in interstate water discussions.

Program of Arizona Department of Water Resources Office of Assured and Adequate Water Supply. This program operates within designated Active Management Areas (AMA) to ensure the availability of water for new subdivisions for the next 100 years. A public report from the Arizona Department of Real Estate (ADRE) that allows subdivision lots to be sold will only be issued if the 100-year water supply has been demonstrated to be legally, physically, and continually available.

A demonstration of a 100-year water supply may also be required.
