What to do about a house in San Diego County
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 4,211 square miles, under one square mile of San Diego County maps onto soluble rock. With about 3,298,799 residents (783 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 298 map points about 3.8 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.
