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 353 of Caledonia County's 649 square miles on soluble rock. With about 30,535 residents (47 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 551 map points about 1.1 miles apart, so a pocket smaller than that can be missed or overstated.
