Flood Proofing Cities

New Orleans: Solution
One new idea for New Orleans was already in development before Katrina. Construction has begun on a sophisticated hurricane floodgate that would close across the Harvey Canal in the event of a storm surge. The $36 million floodgate will protect 250,000 people in the West Bank area of New Orleans, which was relatively unscathed by Katrina, from another storm. When the new barriers are finished, they will be the first hurricane-specific canal barriers of their kind in New Orleans and most likely the first new flood proofing in the city since Katrina.
