As soon as the destructive path of Hurricane Sandy became evident, I got emails and calls from colleagues who, like me, worked in disaster recovery situations on the Gulf Coast. When the clean-up gets underway, could this be an opportunity for the Eastern Seaboard states to apply some of the rebuilding lessons of the Gulf after Katrina? Is there a role for Katrina Cottages?
Well, sure. If there’s one upside in the succession of devastating weather events over the last decade, it’s the opportunity to build on lessons learned. Time between disasters dulls response capacities; shorter gaps refine best practices. And for my money, no lessons are worth more than those connected with the evolution of sustainable neighborhood design.
Just after the close of World War II, the last Great Migration in the United States — the move from the city to the new suburbs — began to emerge, fueled by new roads, low congestion, and modest energy costs. It was a new beginning, a chance to shake off the past, and it came complete with the promise of more privacy, more safety, and easier financing.
