Any time you build a city below sea level right next to the ocean any decent amount of rain is a bad thing. The storm strength wont be as strong as Katrina (what they are saying) but hopefully they took lessons from before and can take a better hit than before. Good luck guys and be safe.
I know it sounds crazy, but Dr. George Friedman, a geopoliticist who heads the Stratfor Group a geopolitical consortium that advises the joint chiefs among others, has written at length about what allowed the United States to become the power that it is. In brief we have the largest contiguous area of arable land (the midwest) that can feed us and the world, and we have a river system(the Mississippi) that can deliver our goods cheaply to the rest of the world, and guess what city he felt was the most important part of controlling this system: The one built near the gulf below sea level. He went on to say the Battle of New Orleans was the most important war we have fought in our development towards superpowerdom. As a New Orleans native I know many people think it a backwards place, we have been called the northernmost city in the Carribean, etc...etc..., but no informed American should discount the importance of this city and it's people to the development of our country. To this day the Port of New Orleans is absolutely critical in dispersing the widest range of goods from bulk, to petrochemical, to containerized finished goods, to cruise ships, to general cargo's. Up until 2000 every president felt it was worth investing in our levee system, it was of significant importance. Some time shortly after 2000 it was determined that the cost did not equal the benefits, but Iraq apparently did, I would love to see those equations.
