What to do about a house in Ascension Parish

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

Across 290 square miles, under one square mile of Ascension Parish maps onto soluble rock. With about 133,534 residents (460 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 561 map points about 0.7 miles apart, so a pocket smaller than that can be missed or overstated.
