No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 288 square miles, under one square mile of Durham County maps onto soluble rock. With about 343,628 residents (1,195 per square mile), most of the county is built up, so a mapped unit is likely to sit under somebody's street. The figures come from 269 map points about 1.0 miles apart, so a pocket smaller than that can be missed or overstated.
