Toots, ain't so, you can find lotsa places in FL where you have a strong commitment of environment (egads, ask the Deltonas about Marco Island circa 1970s
); Sanibel, the Panhandle coast from Cape San Blas to and around the southern turn, the latter two have no allowance for any structures over 36' feetish. If set apart means different, perhaps, but not exclusive.
And what has come of all that, btw. Sanibel is practically an estuary in which humans cohabit but their beaches are screwed with red algae drift. Now they are reporting 4-8 degree temp jumps in the Gulf, the sharks have bailed 8 weeks early, shellfish washing ashore deader than, er, shells, nope, no connection to any known tide or drift.
Your looking at a major change in the landscape effects which will certainly be felt in SoWal now that they have "reclaimed" 4,000 acres of wetlands NW of PC for an airport. Those eastern originating planes, you know everyone has to take a dump right before landing, where do you think that power flush toilet is gong to rain that stuff?
