"You mean they don't...are you kidding me??"

Of course they don't. Salt water weighs 66 pounds per cubic foot. Say, 1.1 metric tons per cubic meter. Given a Cat. 5 with at least a storm surge of 10 meters, the wave foot is going to hit any structure that is on land in the Keys. A wave running in front of a hurricane is going to be moving at 60 mph(say 100 kph) or more and is going to have a cross sectional mass that rivals a fully loaded tractor-trailer rig. So you have the equivalent of running a fully loaded tractor-trailer into any structure that is there every few seconds. Now this is a condition that can go on for hours. Suffice it to say that nothing human made that can't survive a direct nuclear strike can survive under these circumstances. So why bother with air supply? If it gets that dire, they are all toast any way.

When you talk about hurricanes larger than a minimal Cat. 3, keep in mind the nuclear analogy. There is nothing in human experience, with the possible exception of the breeching of the Bosophorus or the Straits of Gilbratar, that compares. You design such things to cover the most likely case instead of the worst case. Like with New Orleans, you can't get approved for the worst case, unless you are the Netherlands, all you can hope for is the most likely case.
