I don't think that any engineering company would recommend reproducing Nawlins as it was; they would like to rebuild with a redundant system of safeguards. The Corps of Engineers thought the design protected against Category 3 hurricanes; it is possible to design for Category 4 and 5 hurricanes. This is a question for engineering trade studies: "Does the increased protection justify the cost?" This is a political decision...not party politics but the allocation of scarce resources.
Before the disaster, undertaking the destruction of neighborhoods [particularly the low income areas] was not tenable. These were the areas that were destroyed by winds and water. Surely, if we can spend tens of billions on "improving" traffic flow in Boston, there is justification for rebuilding New Orleans.
On its founding, New Orleans was the first "hump" of ground above sea level that could take ocean going vessels. That was the reason that the site was selected. Today, the French Quarter is still about 3 feet above sea level.
Rebuilding only the port system might not be the complete solution. People like to live near where they work; so I doubt if the daily bussing of people 60 to 100 miles to the port system is tenable. While this is not the complete solution, a billion dollars can bring to NOLA a lot of fill dirt....$10 billion a lot more.
It is time to review and redesign the system of levees that were built fifty years ago to minimize/prevent annual flooding which renewed the wetlands south of New Orleans....otherwise, we may lose NOLA to the sea.

Well spoken, Jay. I think the best thing would be leaving the flooded, and future flood-prone areas as business estates, and remove all the residential estates out of it to higher grounds, so next time you won't have to struggle with the rescue of hundreds of people from their homes, but just with the damage occurring on buildings and wares. That seems to be a standard practice in other countries to handle flood-threatened areas, to restrict the settling there.
A few last words on politics from me. I admit I'm not a Bush voter, and that I don't really like him, but that's no reason for blaming it all on him. It's pretty obvious that Nagins and Bianco clearly get a big part of the responsibility for the chaos that resulted from Katrina pounding NO - the evacuation was started too late, and was not coordinated with neighboring states. Just giving the "Everyone outta here" hours before the storm arrives and sending all those who didn't have an opportunity to get out to the football stadium (whose sanitary equipment might be suited to cope with ten thousands, but not during a timespan of days, without working sewage drainage) is no well-planned evacuation. Transportation for those without cars would have had to be provided, and at least one exit road especially for those. Plus, intensive care patients and other sick persons should have been evacuated before, to other hospitals.
Those aren't the only measurements that should have been taken, but it's my idea of a start. The power of Katrina was well-known to meteorologists, and I can't imagine they didn't warn the officials, but like in a TV catastrophe movie, those procrastinated till the last moment until they pushed the red button. And I don't mind whether those were Democrats, Republicans or whoever.
