What to do about a house in Bristol County

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

Across 553 square miles, under one square mile of Bristol County maps onto soluble rock. With about 588,593 residents (1,064 per square mile), most of the county is built up, so a mapped unit is likely to sit under somebody's street. The figures come from 499 map points about 1.1 miles apart, so a pocket smaller than that can be missed or overstated.

Worth reading for this county: how these percentages are measured, and the warning signs that apply anywhere.
