April 24, 2009 -- Levees and floodwalls cannot provide absolute protection for New Orleans against overtopping or failure in extreme events, says a new report by the National Academy of Engineering and the National Research Council. The voluntary relocation of people in vulnerable areas should be considered. If relocation is not feasible, the first floor of buildings should be elevated to the 100-year flood level.
