A nature preserve has been created behing North Masanborough Jetty? You mean the island. Confusing? Have you seen fort Fisher lately. The sand is gone there is mostly exposed rock and slippery sand bags Not to mention the amount of drownings each year in that area because of the rips that are created. The failures. South End Jetty and Shell Island almost fell in years ago. Nature is bigger than man. Structures are temporary and only cost more money in the future when they fail. Nature will do what it will. Plant sea oats stay off the dunes at hope your home doesn't wash in!
