dc.description.abstractThe purpose of this study is to evaluate coastal storm damage reduction along Bogue Banks, a barrier island approximately 25 miles long located on North Carolina’s central coast in Carteret County. The feasibility study is a cost-shared effort with Carteret County as the non-Federal study sponsor. Project Delivery Team (PDT) representatives included participants of Federal, State, and local governments in the effort to identify cost-effective, publicly acceptable, and environmentally and technically sound alternatives to reduce storm damages along the project shoreline. This study identified coastal storm damage problems on Bogue Banks, inventoried opportunities for addressing these problems as well as any planning constraints that could impact plan formulation, and analyzed alternatives. This analysis identified the National Economic Development (NED) plan, which is the plan that maximizes net benefits to the nation through reduction of future storm damages. The island of Bogue Banks is located in Carteret County along North Carolina’s central coast. Bogue Banks is the longest island south of Cape Lookout, and is a 25 mile long barrier island, stretching from Bogue Inlet on the west to Beaufort Inlet on the east. The barrier island, separated from the mainland by Bogue Sound, runs east to west, with the ocean beaches facing due south. Bogue Banks is developed and can be accessed by one of two bridges across Bogue Sound, either from Morehead City to Atlantic Beach, which is the more heavily traveled bridge, or from Cape Carteret to Emerald Isle. The State park/communities of Bogue Banks are (from east to west) Fort Macon State Park, Atlantic Beach, Pine Knoll Shores, Salter Path/Indian Beach, and Emerald Isle. Bogue Banks includes some hotels/motels but is dominated by private homes. Bogue Banks also contains areas of maritime forest. Stores and other commercial properties are found in all five main communities. The footprint of the study area includes the marine environment offshore of Bogue Banks, the barrier island, and the sub-aerial terrestrial beach. In all cases where technically sound and environmentally feasible, both structural and non-structural measures were considered in the development of alternative solutions to the ongoing coastal storm damage reduction problems along the project area. The nonstructural measures analyzed included demolition and relocation; retreat; and floodplain and regulatory restrictions. Demolition and relocation was found have greater costs than benefits, and therefore, was not recommended for implementation. Retreat was not considered a practicable alternative given the narrow width of the barrier island; and regulatory restrictions are assumed to be continued in perpetuity as an integral part of any alternative. The structural measures analyzed in detail (dune and berm construction) were shown to have a more favorable benefit/cost ratio and provided the greatest potential for an effective solution. The Recommended Plan is the NED plan (Alternative 9), which consists of an 119,670 linear feet main beach fill (22.7 miles), with a consistent berm profile across the entire area, and dune expansion along 5.9 miles of the project shoreline. The main beach fill is bordered at the ends of the project by a 1,000 ft tapered transition zone berm. Material for the beach fill would be dredged from offshore borrow sources and transported to the beach for beach fill construction. The renourishment interval for the project is three years.en_US
