The Town of Topsail Beach is committed to maintaining its beaches through the process of beach nourishment. Beach nourishment describes the process by which sediment (usually sand) that is lost through erosion is replaced from sources outside the eroding beach. This creates a wider beach that is better able to withstand the natural causes of erosion. The repetitive process of beach nourishment maintains the natural barrier that provides coastal homes and buildings protection from the ocean. The Town of Topsail Bach is able to maintain their beach nourishment program through a "Federal 50 Year Project" and a "30 Year Beach Management Plan".
