The next step for one property

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

Across 2,109 square miles, under one square mile of Lake County maps onto soluble rock. With about 10,698 residents (5 per square mile), much of the land is open, and the mapped rock may sit far from where people actually live. The figures come from 299 map points about 2.7 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.
