No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 798 square miles, under one square mile of Arapahoe County maps onto soluble rock. With about 666,918 residents (836 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 365 map points about 1.5 miles apart, so a pocket smaller than that can be missed or overstated.
