Retain and restore those buildings that can be salvaged. Due to damage from contaminated water, extensive measures will be required to deal with mold. Gut-rehab will be required for many of the estimated 80% of the city’s 200,000 homes that have been damaged and, of course, many homes will not be salvageable. Building codes should address resistance to non-catastrophic flood damage—for example, the most flood-prone lower floors of houses should have no paper-faced drywall, no ductwork, no air handlers, no wall-to-wall carpeting, and no electrical service boxes. Retaining the character of New Orleans, which is defined in part by its vernacular architecture and its diversity, should be a high priority.
