Get a sinkhole or geotechnical inspection before buying, building or adding weight to a foundation.

That works out to roughly 88 of Peach County's 150 square miles on soluble rock, 88 of them with the rock at or near the surface. With about 29,213 residents (194 per square mile), homes are spread across towns and farmland, and a mapped unit may or may not reach the developed parts. The figures come from 501 map points about 0.5 miles apart, so a pocket smaller than that can be missed or overstated.

Two things to read before deciding: the signs to look for and how an inspection works, and how these percentages are measured.
