At least until the sea level rises more than 200-250 feet.

Elevation of Southern Florida

The very low topography of southern Florida is evident in this color-coded shaded relief map generated with data from the Shuttle Radar Topography Mission. The image on the left is a standard view, with the green colors indicating low elevations, rising through yellow and tan, to white at the highest elevations. In this exaggerated view even those highest elevations are only about 60 meters (197 feet) above sea level.

For the view on the right, elevations below 5 meters (16 feet) above sea level have been colored blue, and lighter blue indicates elevations below 10 meters (33 feet). This is a dramatic demonstration of how Florida’s low topography, especially along the coastline, make it especially vulnerable to flooding associated with storm surges. Planners can use data like these to predict which areas are in the most danger and help develop mitigation plans in the event of particular flood events.

Down the center of the state there is a ridge that is above 75 feet above current sea level, That would become a string of islands, as would the red clay ridges in North Florida. The red clay ridge my farm is on (outside of Tallahassee) is 209 feet above sea level at the highest, about the same height as the state capitol building hill.
