Parcel (Landbase) Map Description

Overview

GIS Division parcel maps show Pima County parcels, parcel access and streets. These maps differ from Assessor Record Maps maintained by the Pima County Assessor's Office in these ways:

• GIS Division parcel maps seek to describe physical reality and proposals. For instance, the maps may show each lot in a mobile home park where the entire park is one legal parcel. In cases like this, each lot has the entire park's tax code.

• GIS Division parcel maps show "seamless" parcels. That is, they have been stretched or "rubber-sheeted" where necessary to ensure there are no gaps or slivers between subdivisions and sections. These anomalies occur when joining coordinate geometry (COGO) drawings used in parcel and subdivision legal descriptions. The intent is to accurately display parcel and street relationships with minimal sacrifice of dimensional accuracy. The resulting maps are good for planning, overlaying facilities (sewer, gas, water, etc), and seeing the relationships between parcels.

Non-Taxcoded Parcels

Some areas have not been assigned a parcel code by the Pima County Assessor. These areas are given the following codes:

999999991	Non-private areas on unincorporated Pima County land or incorporated jurisdiction land
999999993	Drainageways
999999994	Non-private areas on state, federal or tribal land
999999999	Unknown

With the exception of "999999999 - Unknown" these areas are all non-private land. The "Unknown" areas may be non-private land or they may be pending assignment of a parcel code by the Pima County Assessor.

There is a layer on our MapGuide map called "Parcels - Non-taxcoded" that displays these areas. The Non-taxcoded Parcels layer is visible at 1:50,000 scale and closer.

Many of these non-private land areas can be researched through subdivision plat maps. If there is no subdivision plat for the area, consult the Pima County DOT Engineering Information Management Section which has further information on Pima County Government property rights and rights-of-way.
