Edgefield County, South Carolina
Edgefield County is a small, rural county in the Central Savannah River Area of western South Carolina, sitting directly across the Savannah River from Augusta, Georgia, with the town of Edgefield as its seat. Growth is exurban and spills over from the Augusta-North Augusta metro area, so proximity to the Georgia line and the North Augusta corridor, more than the rural interior, drives residential demand.
