Sinkhole risk in Kent County, DE: No soluble rock mapped

The next step for one property

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

Across 586 square miles, under one square mile of Kent County maps onto soluble rock. With about 192,690 residents (329 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 267 map points about 1.5 miles apart, so a pocket smaller than that can be missed or overstated.

Two things to read before deciding: how these percentages are measured, and the warning signs that apply anywhere.
