Twelvemile Swamp and the surrounding wetlands dominate this landscape south of Jacksonville, at the boundary where Duval County meets St. Johns County. The area shows a distinct contrast between the rapidly expanding suburban corridors of Nocatee and Durbin and the preserved wild lands of the Twelve Mile Swamp Conservation Area Trail. These conservation efforts protect the intricate hydrology of the region, where numerous waterways like Durbin Creek and Sampson Creek weave through the lowlands. Along the eastern edge, the Intracoastal Waterway and Tolomato River provide a vital maritime passage, separated from the interior by Scrub Ridge. The map captures the recent footprints of modern development alongside older place names like Hilden, illustrating the shifting land use from coastal wetlands to residential communities.
