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

Across 413 square miles, under one square mile of Summit County maps onto soluble rock. With about 538,370 residents (1,305 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 348 map points about 1.1 miles apart, so a pocket smaller than that can be missed or overstated.

Two things to read before deciding: why gypsum and salt move faster than limestone, and how these percentages are measured.
