Barrier islands are just that. Build at your peril and GTFO if a hurricane is coming. I rebuilt a house on Garcon Beach near Pensacola when hurricane Dennis hit and then Ivan 2 months later. One kicked their butt and the second finished them off. The house I worked on was on the East Bay, not even on the beach, and was about 2 feet above high sea level to slab with 8' pilings and 2' floor joists. A wood piling went through the seaward side of the house 6' up on the main living floor. That's how high water got. Trust me when I say I know what these folks are in for over the next 2 years. Our state government seems to be on it thank goodness. (not political) Prayers up for all those effected.
