McClain County 9-1-1 Trust Authority maintains accurate mapping and GIS data of McClain County roads and addresses, using information from cities, towns, and other agencies within the county.
To encourage simplicity and assist emergency responders, the county road system was implemented and signage placed throughout the county. Major east-west roads are numbered, starting with 100th Street located along the southern edge of the county and gradually increasing toward the northern tip of the county. Major north-south streets are named after major streets in the Oklahoma City grid that the county road best aligns with (e.g. Santa Fe Avenue would, if extended northward, eventually connect with the street of the same name in Oklahoma City).
Our maps are maintained digitally using ESRI ArcGIS. For some applications, we make our map information available to outside agencies in Oklahoma to assist in their missions. We provide maps to the McClain County Election Board, the McClain County Commissioners, various cities and towns within the county, as well as sharing information with government associations like ACOG. If you are in need of county GIS data, please contact our office for further information.
