The reconstruction of New Orleans may be years away, but plans are coming off the drawing board. Andres Duany and his team of “New Urbanists” have come to New Orleans with their vision of the future: 19th century-style town plans that encourage compact living and walkability. That’s roused the ire of some modernist architects, who think the New Urbanist vision is a nostalgia theme park. Kurt Andersen travels to Louisiana to find out whether the future is in the past. Produced by Michele Siegel with Jason Rhein.
