A GIS (Geographic Information System) is a combination of computer hardware and software, spatial data, and trained personnel that allows real world conditions to be mapped and analyzed. For example, a map can show features such as roads and rivers. A GIS can display (map) the features, and also highlight specific conditions such as "what roads in Doña Ana County are within 100 feet of the Rio Grande?"

Doña Ana County's GIS contains over one hundred seventy-five geodatabases (or "layers") of information including road centerlines, address points, political districts, jurisdictional boundaries, zoning and land use information, and property ownership information.

Start by filling out a petition available at the Planning Department, 845 N. Motel Blvd., Las Cruces, NM 88007. County staff will explain the road naming procedure.

No. County ordinances prohibit the use of certain names including family surnames and road names already in use in the County. The County Addressing Specialist can tell you if the proposed road name complies with the ordinances.

Yes, but in order to change the name of a road, a minimum of 75% of property owners along the road must agree to changing the name. A road name can only be changed once every seven years.

Yes! Street addresses are used for many purposes, including emergency services dispatching, generating voter rolls, and package delivery. Street addresses can also be used for mail delivery (contact the US Post Office to see if mail delivery is available in your area and for zip code information).

If you need an address issued or a new street named then contact Carlos Benevides, Addressing Specialist at (575) 525-6122.
