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 593 square miles, under one square mile of Webster Parish maps onto soluble rock. With about 35,184 residents (59 per square mile), much of the land is open, and the mapped rock may sit far from where people actually live. The figures come from 256 map points about 1.5 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.
