What to do about a house in Accomack County

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

Across 449 square miles, under one square mile of Accomack County maps onto soluble rock. With about 33,411 residents (74 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 403 map points about 1.1 miles apart, so a pocket smaller than that can be missed or overstated.
