What to do about a house in Lafourche Parish

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

Across 1,070 square miles, under one square mile of Lafourche Parish maps onto soluble rock. With about 95,342 residents (89 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 399 map points about 1.6 miles apart, so a pocket smaller than that can be missed or overstated.
