i say this as a licensed architect that has studied vernacular architecture of flood-prone and semi-tropical regions . . .
this is actually a great entry. use of recycled materials. overhangs as sunshades. maximize natural ventillation by use of windows on opposing sides of the home. you know it's going to flood, so you build it on stilts.
when the french first started colonizing new orleans, they figured out the important stuff pretty quick - that it WILL flood, so you'd better design your building around that simple fact. note that nearly every plantation house and french creole cottage down there has been flooded at one time or another - often repeatedly. all of the critical living spaces are above the ground floor. when it starts flooding, you move your important stuff upstairs and wait for the waters to recede.
also note that most of the buildings that were undamaged by the flooding were built before the 1920's, with the main floor at least 4 feet off the ground. homebuilders in the area, for some reason, have since forgotten that floods happen when you live below sea level in the semi-tropics.
those that WANT to live in new orleans will figure out a way to make it happen. socialist social engineering won't work. new orleans has a golden opportunity to hoist itself from the swamp (forgive the pun) of dependency.
there are many citiziens who WANT to pitch in and make new orleans great again. they will do it if government will "promote the[ir] general welfare and let them DO IT.
