What to do about a house in Cass County
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 490 square miles, under one square mile of Cass County maps onto soluble rock. With about 51,550 residents (105 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 383 map points about 1.1 miles apart, so a pocket smaller than that can be missed or overstated.
