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 314 of Mayes County's 655 square miles on soluble rock, 314 of them with the rock at or near the surface. With about 40,144 residents (61 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 380 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.
