SC/NC Boundary Program

1. Why did South Carolina and North Carolina re-establish the state line?

When jurisdictional issues arose along the state boundary between York County, SC and Gaston County, NC in the early 1990s, the SC Geodetic Survey and the NC Geodetic Survey signed a Memorandum of Agreement in April 1993 to cooperatively re-establish the South Carolina – North Carolina boundary. The intent was to avoid a litigious dispute, such as occurred between South Carolina and Georgia regarding their boundary in the Lower Savannah River area. That contentious dispute cost the South Carolina $10 million and 26 years of litigation and negotiation, that involved the U.S. Supreme Court and Congress, to resolve 25 miles of boundary.
