What to do about a house in Casey 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 105 of Casey County's 444 square miles on soluble rock, 105 of them with the rock at or near the surface. With about 15,948 residents (36 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 590 map points about 0.9 miles apart, so a pocket smaller than that can be missed or overstated.
