The next step for one property

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 51 of Yadkin County's 335 square miles on soluble rock, 51 of them with the rock at or near the surface. With about 37,995 residents (113 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 339 map points about 1.0 miles apart, so a pocket smaller than that can be missed or overstated.
