Hypothetically, Is it possible to build a nuclear bunker/shelter in Florida?

I’ve always thought about how screwed I would be if there was ever a nuke. I live in central Florida and for any of you that don’t know, it’s almost impossible to build a basement or anything underground. The soil is too wet and the whole state is covered in limestone. If someone was to build a basement they would be exposing the foundation of their home to water damage and paying up the ass for maintenance.

Since underground shelters are almost impossible, is there any other kind of shelter/bunker options for floridians?
