What to do about a house in Bladen 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 328 of Bladen County's 875 square miles on soluble rock, 328 of them with the rock at or near the surface. With about 29,777 residents (34 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 253 map points about 1.9 miles apart, so a pocket smaller than that can be missed or overstated.
