Abstract: This General Re-evaluation Report (GRR) summarizes efforts directed at evaluating the continued feasibility of not yet constructed hurricane and storm damage reduction features along the coastline adjacent to the Town of Topsail Beach, on Topsail Island, North Carolina. Originally authorized as the West Onslow Beach and New River Inlet, NC shore protection project in the Water Resources Development Act (WRDA) of 1992, the local sponsor was not able to execute the Project Cooperation Agreement, and it was not subsequently constructed. During the intervening years, increasing storm damage has occurred along many portions of the shoreline of this part of North Carolina, notably by Hurricanes Bertha and Fran in 1996, and Hurricane Floyd in 1999. This increased coastal erosion threat, along with the increasing threat to existing and new development within the Town of Topsail Beach, led to initiation of this post-authorization General Reevaluation study in 2001. This report was prepared in compliance with the Energy and Water Development Appropriations Act of 2001 that pertains to the authorized project for Topsail Beach. The study area consists of the Town of Topsail Beach, its shoreline, and adjacent borrow areas off the coast. The remainder of Topsail Island to the north of the Town of Topsail Beach is being studied under a separate study authority. This study serves as a reevaluation of the original report to the Congress of the United States and to identify if there are technically, environmentally, and economically feasible means of reducing damages caused by coastal hurricanes and storms within the identified study area. It also serves to examine the feasibility of providing hurricane and storm damage reduction features along a portion of the shoreline not originally authorized for construction, within the Town of Topsail Beach. The study team integrated representatives of Federal, State, and local governments, in the effort to identify cost-effective and environmentally- and technically-sound alternatives to reduce damages within the Town of Topsail Beach, and to its adjacent shoreline. The process fully integrated the Corps’ “Twelve Actions for Change”, in all aspects of the study process. The study effort identified a “National Economic Development” (NED) plan, which would maximize net benefits to the nation through reduction of future storm damages, as well as a “Locally-Preferred Plan (LPP), which is a plan that the local sponsor, the Town of Topsail Beach, supports. The recommended plan of action is construction of the Locally-Preferred Plan. The recommended plan, referred to in the GRR as “Plan 1250X”, consists of a sand dune constructed to an elevation of 12 feet above the National Geodetic Vertical Datum (NGVD), fronted by a 50-foot wide beach berm constructed to an elevation of 7 feet above NGVD. This dune and berm feature would extend 23,200 feet, with a 2,000 foot northern transition fill, and a 1,000 foot southern transition fill, for a total length of 26,200 feet. This total project length exceeds the originally authorized project length of 19,200 feet.
