Groundwater Savings Facility

Purpose and intended use - This dataset is used for analysis by the ADWR Recharge and Recovery group. A Groundwater Savings Facility (GSF) Permit (A.R.S. § 45-812.01) allows the permit holder to deliver a renewable water supply, called "in-lieu" water, to a recipient who agrees to replace groundwater pumping with in lieu water, thus creating a groundwater savings. The recipient must agree in writing that for every gallon of in lieu water received, the recipient will reduce groundwater withdrawals from within an Active Management Area (AMA) or Irrigation Non-expansion Area (INA) by one gallon. Information regarding the criteria a facility must meet in order to be permitted as a GSF is included in A.R.S. § 45-812.01. Data creation methodologies, processing, and quality - Based on ADWR IGFRs (58-) and/or associated Irrigation District boundary (57-) data. Each shape was created to reflect the outside boundary of the GSF, based on recipients’ IGFRs (58-) and/or the associated Irrigation District boundaries (57-). This is a dissolve of the LIB.rechargeGSF layer based on the Program, Certificate, Conveyance and Name fields. Currency – This data is manually updated when there is an update to the underlying data or an error is brought to the attention of ADWR. Last updated August 2025.

Groundwater Use Right 58

An Irrigation Grandfathered Right (IGFR) is a right to irrigate land in an active management area that was legally irrigated any time between 1975 and 1979, based on crops historically grown, for which a certificate has been obtained, with a few exceptions for substitution or transfer of acres under specified circumstances. The process for determining acres entitled to and for calculating a groundwater allocation is specified in A.R.S. § 45-465.
AMA INA

This data is a query from groundwater_basin_ADWR to create AMA boundaries. According to ARS 45-402(13) "Groundwater basin" means an area which, as nearly as known facts permit as determined by the director pursuant to this chapter, may be designated so as to enclose a relatively hydrologically distinct body or related bodies of groundwater, which shall be described horizontally by surface description. The 1980 Arizona Groundwater Code recognized the need to aggressively manage the state’s finite groundwater resources to support the growing economy. Areas with heavy reliance on mined groundwater were identified and designated as Active Management Areas (AMAs). The five AMAs (Prescott, Phoenix, Pinal, Tucson, and Santa Cruz) are subject to regulation pursuant to the Groundwater Code. Each AMA carries out its programs in a manner consistent with these goals, while considering and incorporating the unique character of each AMA and its water users. In the Phoenix, Prescott, and Tucson AMAs, the primary management goal is safe-yield by the year 2025. Safe-yield is accomplished when no more groundwater is being withdrawn than is being annually replaced. In the Pinal AMA, where the economy is primarily agricultural, the management goal is to preserve that economy for as long as feasible, while considering the need to preserve groundwater for future non-irrigation uses. In the Santa Cruz AMA the management goal to maintain a safe-yield condition in the active management area and to prevent local water tables from experiencing long term declines.

PLSS Land Ordinance

Public Land Survey System or PLSS related features are Sections, Township/Range, and Tracts. Often used in legal descriptions, tracts provide a reference grid for describing or locating parcels of land or other features in Arizona. Stored and published in State Plane Arizona Central 0202 International Feet (WKID 2223). Intended for web maps, ArcGIS Online, and use in ArcGIS Pro. Provides a reference for County employees and the general public to determine Public Land Survey System or PLSS related features. These are government tracts, sections, township and Range located within Yavapai County. Section feature class represents the GIS Version of the Public Land Survey System in Arizona including both rectangular and non-rectangular surveys. Sections are part of the Public Land Survey System (PLSS), are smaller than townships, 36 sections covers one township. Regular sections are 640 acres. The first section starts in the northeast corner of a township. Section numbers increase moving in east-west rows. Then, the section number increases wraps back and forth until the section numbers fills in the entire township. Sections published visible range is 1:500,000. Townships are part of the Public Land Survey System, normally a rectangle approximately 6 miles on a side with boundaries conforming to meridians and parallels. The purpose of the data is to provide location identification for locating legal documents to enter meet and bounds attributes for changes to parcels. Assessor Cartography and ITS Data Services GIS staff maintained this data based on survey control points and other survey information collected. Recommended visibility range is 1:2,000,000. Label class can be based on field TRFULL. Tracts or also called Government Lots are irregular portion of a Section as formed by a meandering body of water, impassable object, or another boundary (state, reservation, grant). These “lots” are used in Sections with an irregular shape or acreage (containing less than or more than the 640 acres seen in a standard Section). While called lots, these are not the type of lot that you would see in a platted subdivision. Published visible range is 1:250,000.

National IA Frequency Zones Federal Public

Initial attack frequency zones are used by pilots and dispatchers for purposes of response to incidents such as wildland fires. Initial attack frequency zones are agreed upon annually by the Communications Duty Officer at the National Interagency Fire Center (NIFC), other frequency managers, and the FAA, and can't be changed during the year without required approval from the CDO at NIFC. Each zone has assigned to it FAA-issued frequencies that are to be used only within the zone boundary. The initial attack frequency zones are delineated to help ensure that frequencies used do not "bleed" over into other incident areas and causing issues for incident communications. The data contains no actual frequencies, but does contain the zones in which they are used. January 2025 Changes: * Changed geometry for MT01, MT02, and MT04 to match boundary changes for Missoula Dispatch and Helena Dispatch Boundary * MT02 modified northern border to be even with the along 48 degree line * MT01 modified northern border to be even with the along 48 degree line * Updated dispatch boundary between Grand Junction COGJC and Moab Interagency Fire Center UTMFC * Updated geometry for CO01, CO02, CO06 & CO07 to match new dispatch boundary and to simplify the dispatch perimeters * Updated geometry for ID04&ID05 to match the dispatch boundary changes between the two
