Rebuilding

So now that New Orleans has been pretty much wiped off the map; when they rebuild can they truck in some dirt so that it is above sea level? Every time a hurricane or tropical storm is predicted for New Orleans, the threat of flooding is real since it is 10 feet (about 3.2 m) below sea level. I know in the past they would not make it level because buildings had been there for centuries and you couldn't build up one section of the city while leaving another part of the city to collect the run off into its section. Now there is no excuse. Yes, it will add to the expense of rebuilding but wouldn't it make sense to rebuild with the idea of not setting yourself up to have to rebuild againthe next time a hurricane hits?
