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 374 square miles, under one square mile of Wicomico County maps onto soluble rock. With about 106,329 residents (284 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 508 map points about 0.9 miles apart, so a pocket smaller than that can be missed or overstated.

Two things to read before deciding: how these percentages are measured, and the warning signs that apply anywhere.
