Being a city below sea level, New Orleans always will be vulnerable to flooding from hurricanes. Hopefully, enough improvements can be made in the flood control system to protect the city from another Katrina. If not, the population may not return to its pre-storm level for a long time, if ever. As much as I like New Orleans, the location is not a good place for a large city. Given the costs of flood control improvements and rebuilding, would relocating the city to a safer site be a reasonable alternative?
