Dozens of coastal communities would be sacrificed under a plan to build a massive hurricane protection bulwark for Louisiana. "We believe that it's probably not possible to provide adequate protection that people should be living down there," said Randy Hanchey of the Louisiana Department of Natural Resources. Current hurricane barriers would not protect communities against storms as strong as Hurricane Katrina. The U.S. Army Corps of Engineers, ordered by Congress to design its own set of storm defenses, reached the same conclusion, project manager Tim Axtman says. "The reality is, the cost of protection doesn't equate to what's there," he says.
