The Mapping/GIS Services section is responsible for creating and maintaining maps that are needed and requested by various
County departments, residents, developers and neighboring jurisdictions. The Mapping Section is a resource to all County departments,
providing continuously updated maps as follows:
♦ Parcel maps to the Assessor's Office
♦ Road maintenance maps to Road and Bridge and Transportation Divisions
♦ Base information for the County's GIS and Internet Mapping Service
♦ Zoning maps for the Planning and Zoning Division
♦ Current aerial photography in digital and hard copy format
♦ Base maps and geodetic control surveys for the County's GIS projects
♦ Special CAD and GIS projects as requested by County departments
In addition, the Mapping section assigns street names and addresses in the unincorporated portions of Arapahoe County, including
all street names and addresses for land development projects; all addresses for building permits; and all requests to change
street names and address.
To provide better accuracy for the County's maps, Mapping personnel conduct surveys to extend the County's Horizontal and
Vertical Control Networks.
As a referral agency for land development cases within unincorporated Arapahoe County, Mapping section personnel review development
cases, subdivision plats and easement/tract legal descriptions.
