Across 862 square miles, under one square mile of Fort Bend County maps onto soluble rock. With about 958,434 residents (1,112 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 247 map points about 1.9 miles apart, so a pocket smaller than that can be missed or overstated.
