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 693 square miles, under one square mile of San Patricio County maps onto soluble rock. With about 71,467 residents (103 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 245 map points about 1.7 miles apart, so a pocket smaller than that can be missed or overstated.
