What to do about a house in Falls Church city
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 2 square miles, under one square mile of Falls Church city maps onto soluble rock. With about 15,034 residents (7,348 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 472 map points about 0.1 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.
