What to do about a house in Terrell 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 55 of Terrell County's 336 square miles on soluble rock, 55 of them with the rock at or near the surface. With about 8,698 residents (26 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 311 map points about 1.0 miles apart, so a pocket smaller than that can be missed or overstated.
