The fact that the city of NO has sunk below sea level is what caused the prolonged damage and promises to happen again.

That entire region was built up by sediment deposits from the Mississippi river. The deposits and the dry land they provide isn't old, geologically, and settles naturally, irrespective of ocean level.
Much of NO was built on what was a swamp area, below sea level. It's worse now. When weather first flooded the natural levees during the first French rule, the people built them higher, and the cycle repeated. Much later part of the improvement meant controlling the river flow which removed the source of new deposits. Without new deposits the entire coastal region is slowly going under.
I expect knee-jerk levee funding but nothing's going to happen quickly. IIRC, the existing upgrades (long underfunded) weren't slated for completion until 2015.
