What this means before you buy

Sinkholes are uncommon here; watch for new depressions after heavy rain or leaking pipes.

That works out to roughly 3 of Carson City's 145 square miles on soluble rock, 3 of them with the rock at or near the surface. With about 58,148 residents (402 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 552 map points about 0.5 miles apart, so a pocket smaller than that can be missed or overstated.
