Parcels are identified by an Assessor's Parcel Number (APN) consisting of a three digit Book number, a two digit Map number, a three digit Item number, possibly a Split letter. This dataset contains all active parcels within Maricopa County. State and Federal lands are not represented. Vertical parcels are annotated using the Floor field.

The Maricopa County Assessor static parcel maps are made available as zipped PDF files. Map IDs are broken down as Township & Range - Section - Quarter Section - Quarter Quarter. For example 807-18-04-00 would be: 807 -- Township 3 North, Range 4 East 18 -- Section 18 04 -- The SouthEast Quarter 00 -- There are no separate quarter quarter maps. MapIDs are only generated where parcels exist with Maricopa County. Last update of a MapID is indicated by the BEGIN_DATE field.

Assessor Book Boundaries are the aggregated boundaries of the first three digits of an Assessor Parcel Number (APN).

The Year 2000 Land Use coverage was created as a joint effort of MAG and MAG member agency staff. Land Use components were classified into 46 categories. The Year 2000 Land Use coverage is used for a variety of planning purposes including socioeconomic forecasting and air quality modeling.

This dataset contain the parcels from the Maricopa County Assessor's office. The area covered is in Maricopa County (Phoenix metro area), Arizona. Major cities include Phoenix, Scottsdale, Mesa and Tempe. Various types of property usage are depicted in this layer. The most common are residential, commercial, industrial and agricultural properties. Multiple sources were used to collect the information including but not limited to CAD packages, aerial photography, and digitizing from paper maps. Adjustments are made where necessary in the process of updating and some parcel lines are only approximate. In cases where a line adjustment might create a loss of landsize it is typically taken out from the right of way to minimize the loss of landsize in the property. The line symbology for different property lines are not available in this dataset. In addition to standard fields the data has unique assessor parcel number for identification, basic temporal information and the location of property.

REQUIRED: A brief narrative summary of the data set.

The 1995 Land Use coverage was created as a joint effort of MAG (Maricopa Association of Governments) and MAG member agency staff. Land Use components were classified into 24 categories. The 1995 Land Use coverage is used for a variety of planning purposes including socioeconomic forecasting and air quality modeling.

Contains 2010 MAG EXLU and FLU summarized by land use type, for places and Maricopa County. Used by the 2010 land use viewer.

This is the digitized version of a map of the Hohokam canal system in what is now the Phoenix metropolitan area. It is based on the thesis research by J. B. Howard (Howard, J. (1990). Paleohydraulics : techniques for modeling the operation and growth of prehistoric canal systems. Thesis (M.A.)--Arizona State University, 1990). The original paper map is based on previous archaeological data, overlayed onto USGS 7.5 minute quadrangle maps to recreate the canal pattern.

Cross sections as approved by the Federal Emergency management Agency (FEMA) for the Flood Insurance Rate Maps (FIRM)

Parcels are identified by an Assessor's Parcel Number (APN) consisting of a three digit Book number, a two digit Map number, a three digit Item number, possibly a Split letter. This dataset contains all active parcels within the area encompassed by Book Series 500. State and Federal lands are not represented. Vertical parcels are annotated using the Floor field.

Water surface elevations of the base flood as approved by the Federal mergency management Agency (FEMA) for the Flood Insurance Rate Maps (FIRM). The base flood elevation, in feet, is in relation to the National Geodetic Vertical Datum of 1929. Profile baselines are for the Flood Insurance Rate Maps (FIRM). The cross section data are used for the production of Flood Insurance Rate Maps. The Flood Insurance Rate Maps (FIRMs) show different floodplains with different zone designations. These are primarily for insurance rating purposes, but the zone differentiation can be very helpful for other floodplain management purposes. The differentiated floodplain zones are used for the production of Flood Insurance Rate Maps. Maricopa County has been subdivided into FIRM panels for the publication and distribution of FIRMs. Profile baselines are for the Flood Insurance Rate Maps (FIRM).

Floodplain zones as approved by the Federal Emergency Management Agency (FEMA) for the Flood Insurance Rate Maps (FIRM). Differentiated according to the FEMA letter coding scheme.

This map depicts existing and future land use conditions for Maricopa County, Arizona. The Existing Land Use data are derived from Maricopa County Assessor parcels, public land data from Arizona State Land Department, and numerous other sources.

Parcels are identified by an Assessor's Parcel Number (APN) consisting of a three digit Book number, a two digit Map number, a three digit Item number, possibly a Split letter. This dataset contains all active parcels within the area encompassed by Book Series 400. State and Federal lands are not represented. Vertical parcels are annotated using the Floor field.

The Existing Land Use (EXLU) dataset represents land use in Maricopa and Pinal Counties, Arizona. This dataset was created as a joint effort of MAG and MAG member agency staff. This dataset serves as a land use inventory and is used for a variety of planning purposes including socioeconomic forecasting and air quality modeling. Because of the level of generalization involved in creating this dataset, land use boundaries may not be accurate representations of ground conditions if used at small scales. These data were developed primarily from assessor parcel data collected in January 2021 for Maricopa County and October 2020 for Pinal County.
