Have to believe that the rebuild will involve fewer structures and dramatically modified building codes. A simple stick built home on a slab doesn't stand a chance. I have seen a lot of homes on very tall concrete pilings ... 10-12 feet clearance below ... built to withstand storm surges. That might be a requirement simply TO GET insurance. We left Coral Gables in 2014, were not in a flood zone, and our storm insurance was $10,000 a year. That same home today is at a much higher rate ... $15,000 or so. What is a reasonable insurance risk for a home on Ft. Myers Beach, IN a flood zone that is barely a couple of feet above normal high tide? WHO is going to insure a NEW home there today? Not the State of Florida or the taxpayers. Sea levels have risen ... fact. Many areas NOT exposed to flooding under normal conditions are now experiencing flooding frequently (areas of Miami Beach). I envision fewer structures with dramatically modified construction for those islands for any rebuild plans.
