Knowing about places like Guam, and the scope of historical super typhoon damage that exists there, makes me think that they are probably going to rebuild New Orleans with engineering model highlights similar to those listed below.
When I used to live on Guam we got hit by Typhoon Pamela. We would also get these bad earthquakes, too where the house would shift off of the foundation and then shift back on the foundation.
Now, as I wrote in my journal, I can't even begin to imagine what kind of disaster Katrina is, but I guess I can only compare the scope of hurricane it was when I was in the storm of Super Typhoon Pamela on Guam on May 21, 1976, etc. when I was a little girl. I looked up the stats on that storm and they were:
peak gust 160 mph
damage ($ millions) 500
Now as I was mentioning, maybe engineers can apply the similar and new "Model Highlights" that they have in places like Guam to places like New Orleans, perhaps. Something will have to be done with the "below sea level" thing, beyond the levees, perhaps. Engineers will have to figure that out in new model highlights.
I realize that New Orleans has been completely damaged and you wonder what is the point to rebuilding if it will happen again. It has been done before. For example, in 1962, gusts estimated near 185 mph destroyed 95% of all homes on the island. And it wasn't just a one time thing. Guam keeps on getting typhoons/super typhoons.
Other notable typhoons impacting Guam include:
Damage ($ millions)
Super Typhoon Paka
Here are the Model Highlights from Guam. Maybe they will apply some of these to New Orleans when they rebuild.
Model developed in conjunction with leading local meteorologists and engineers
Stochastic database of 1,458 storms reflecting the distribution of possible typhoon events for Guam and Saipan
Wind speeds in the hazard module validated against historical wind speed data from Omar, Gay, Brian, Pamela, and other typhoons
Building vulnerability curves based on regional building code requirements, local design standards, local engineering experts, and vulnerability data from other countries with similar construction standards
Vulnerability curves validated against insured loss data from Typhoon Omar
