What to do about a house in Searcy County

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 304 of Searcy County's 666 square miles on soluble rock, 304 of them with the rock at or near the surface. With about 7,836 residents (12 per square mile), much of the land is open, and the mapped rock may sit far from where people actually live. The figures come from 324 map points about 1.4 miles apart, so a pocket smaller than that can be missed or overstated.
