Southern Coastal Plain (e-j)}} It differs from Georgia's Upper Coastal Plain in that it is lower in elevation with less relief and wetter soils. The United States Environmental Protection Agency defines the Lower Coastal Plain as an ecoregion, part of the larger, interstate Southern Coastal Plain.

Within the subregion flow the major rivers the Altamaha, Ogeechee, Saint Marys, Savannah, Satilla, and Suwannee (all of which, except the Suwannee River, empty into the Atlantic Ocean); the Saint Marys and Suwannee rivers have their origins in the Okefenokee Swamp. The Coastal Plain is also the home to Savannah, the first capital city which was declared in 1733.
