The next step for one property
Sinkholes are uncommon here; watch for new depressions after heavy rain or leaking pipes.
Standard Florida homeowners policies cover only catastrophic ground cover collapse; full sinkhole coverage is a separately priced option insurers must offer.
That works out to roughly 102 of Bay County's 759 square miles on soluble rock. With about 199,718 residents (263 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 561 map points about 1.2 miles apart, so a pocket smaller than that can be missed or overstated.
Two things to read before deciding: what Florida insurers have to cover, and why the 13% under cover still counts.
