The reconstruction of New Orleans is a mess. But maybe that’s good for architecture, writes Chris Hawthorne. “Without Category 5 levees, wetlands restoration along the Gulf Coast or a forward-thinking planning strategy in place, homeowners who choose to rebuild will have to acknowledge the possibility of future flooding in every design decision. And if they approach the reconstruction process with that level of wariness — with their eyes wide open — they will be tapping into a rich architectural tradition in this city, odd as that may sound.”
