Sure. But what you are saying would lead us all to build in one spot of the nation. Woe to those who would venture to the coast, or in to hurricane alley. There will always be mother nature to contend with, no matter where one lives. The best we can do is engineer through technology and foresight the best possible way we can to build where the heck we want! New Orleans has been here longer than you and I. I for one want to see her restored to historical beauty. We can do that. We have the technology to make it even better. It is the army corp of engineers one has to fear. If it were private engineers doing the rebuilding, with over sight, N.O. would be as safe as San Francisco, if not more so.
right build NO better and practical. maybe smaller, high and with levee redund. Also, bring in japanese construction methods(they love concrete, lol)
