Sinkhole risk in Wilcox County, GA: Pockets of it

Pockets of it

Soluble rock at the surface or under thin cover in part of the county.

On soluble rock: 100%
At or near the surface: 28%
Buried under cover: 72%

What this means before you buy

Check the parcel against your state survey sinkhole map, and ask for an inspection if cracks, depressions or sticking doors show up.

That works out to roughly 378 of Wilcox County's 378 square miles on soluble rock, 107 of them with the rock at or near the surface. With about 8,904 residents (24 per square mile), there is effectively nowhere in the county off the soluble rock, town or country. The figures come from 316 map points about 1.1 miles apart, so a pocket smaller than that can be missed or overstated.

Worth reading for this county: why the 72% under cover still counts, and the signs to look for and how an inspection works.
