What this means before you buy

Across 1,363 square miles, under one square mile of Brazoria County maps onto soluble rock. With about 413,224 residents (303 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 584 map points about 1.5 miles apart, so a pocket smaller than that can be missed or overstated.
