What this means before you buy

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

Across 923 square miles, under one square mile of St. Landry Parish maps onto soluble rock. With about 80,869 residents (88 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 497 map points about 1.4 miles apart, so a pocket smaller than that can be missed or overstated.

Two things to read before deciding: why gypsum and salt move faster than limestone, and how these percentages are measured.
