What to do about a house in St. Bernard Parish

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

Across 378 square miles, under one square mile of St. Bernard Parish maps onto soluble rock. With about 44,783 residents (119 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 439 map points about 0.9 miles apart, so a pocket smaller than that can be missed or overstated.
