Where county boundaries are ill-defined, unmarked, or poorly marked, the South Carolina Geodetic Survey on a cooperative basis shall assist counties in defining and monumenting the locations of county boundaries and positioning the monuments using geodetic surveys. The South Carolina Geodetic Survey (SCGS) shall seek to clarify the county boundaries as defined in Chapter 3, Title 4. The SCGS shall analyze archival and other evidence and perform field surveys geographically to position all county boundaries in accordance with statutory descriptions. Physical and descriptive points defining boundaries must be referenced using South Carolina State Plane Coordinates.
