Surveying and Mapping

What We Do

The Surveying and Mapping Division provides project and Geodetic Surveying services to various County programs and departments.

Project surveying includes boundary surveys, topographical surveys, right-of-way surveys, as-built surveys, construction stake-out, and sketches and descriptions for recording purposes. Consulting and expert testimony are provided to the State Attorney's Office and the County Attorney's Office.

Geodetic surveying includes providing the County Geographic Information Systems (GIS) Division with geodetic control for the base map layer of the GIS.
