Since Hurricane Katrina, there have been promises that New Orleans will be rebuilt. But those plans will also likely include a redesigned New Orleans. Reed Kroloff, dean of Tulane's architecture program, says the city's "fine grain" must be preserved. Sociologist George Wooddell shares his pessimism that the population will return. Landscape architect Walter Hood, a University of California-Berkeley professor, says New Orleans must become a denser, more integrated city, both in race and class.
