What to do about a house in Bay County
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 442 square miles, under one square mile of Bay County maps onto soluble rock. With about 102,651 residents (232 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 564 map points about 0.9 miles apart, so a pocket smaller than that can be missed or overstated.
