What to do about a house in Yolo County
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 1,013 square miles, under one square mile of Yolo County maps onto soluble rock. With about 225,251 residents (222 per square mile), homes are spread across towns and farmland, and a mapped unit may or may not reach the developed parts. The figures come from 489 map points about 1.4 miles apart, so a pocket smaller than that can be missed or overstated.
