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 161 square miles, under one square mile of Barrow County maps onto soluble rock. With about 96,294 residents (598 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 568 map points about 0.5 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.
