Colleton County, South Carolina
Colleton County spans the South Carolina Lowcountry between Charleston and Beaufort, with Walterboro as its seat and Edisto Beach as its Atlantic coastal outlet. Much of the county falls inside the ACE Basin conservation area, a federally protected estuarine complex that limits development along the Ashepoo, Combahee, and Edisto rivers, so conservation easements and floodplain boundaries drive what can be built and where.
