What to do about a house in York County
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
That works out to roughly 8 of York County's 991 square miles on soluble rock. With about 220,143 residents (222 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 240 map points about 2.0 miles apart, so a pocket smaller than that can be missed or overstated.
