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

Across 556 square miles, under one square mile of Atlantic County maps onto soluble rock. With about 279,114 residents (502 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 553 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.
