 Long Beach on Long Island, New York, is an example of what can happen when there's no beach re-nourishment. So the entire island under? Under water. Yep. After Superstorm Sandy destroyed more than a thousand homes here, the Corps re-nourished and built up the beach. What we found is that where you had a stable, well-maintained beach, berm, and dune system, the damages were extremely less than where you did not.
