No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.

Across 277 square miles, under one square mile of Kent County maps onto soluble rock. With about 19,557 residents (71 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 425 map points about 0.8 miles apart, so a pocket smaller than that can be missed or overstated.
