Sinkhole risk in Eastland County, TX: Pockets of it

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 176 of Eastland County's 927 square miles on soluble rock, 176 of them with the rock at or near the surface. With about 18,290 residents (20 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 315 map points about 1.7 miles apart, so a pocket smaller than that can be missed or overstated.
