When issues arose regarding 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. This contentious dispute cost the state $10 million and 26 years of litigation and negotiation, that involved the U.S. Supreme Court and Congress, to resolve 25 miles of boundary.

The effort to technically re-establish the 334-mile-long South Carolina – North Carolina boundary that was begun in 1995 was completed on May 3, 2013 when the NC – SC Joint Boundary Commission approved the technical work for the last 91 miles.
