Sinkhole risk in Bosque County, TX: Pockets of it

Soluble rock at the surface or under thin cover in part of the county.

On soluble rock: 26%
At or near the surface: 26%
Buried under cover: 0%

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 257 of Bosque County's 983 square miles on soluble rock, 257 of them with the rock at or near the surface. With about 19,013 residents (19 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 559 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.
