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 598 square miles, under one square mile of Southeastern Connecticut Planning Region maps onto soluble rock. With about 282,602 residents (472 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 573 map points about 1.0 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.
