If we are going to spend billions of dollars to rebuild we might as well do it right.
first of all the oil refineries and oil port are not dependant on the city of NO being there.
Secondly the entire flow of the Mississippi is being captured by a smaller river (there was a thread posted on it here somewhere) that runs through Morgan city. Build a set of locks where the current dam/flood gate is and let nature take it's course. Build the new port in morgan city or there abouts.
Blow the levees and let the lake expand to it's natural borders. NO is a cesspool and will remain one.
My sentiment...exactly
