Sinkhole risk in Warrick County, IN: No soluble rock mapped

What this means before you buy

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

Across 385 square miles, under one square mile of Warrick County maps onto soluble rock. With about 66,339 residents (172 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 628 map points about 0.8 miles apart, so a pocket smaller than that can be missed or overstated.
