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 495 square miles, under one square mile of Richland County maps onto soluble rock. With about 124,853 residents (252 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 316 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.
