Abstract: The U.S. Army Corps of Engineers, Mississippi Valley Division, Regional Planning and Environment Division South, has prepared this Environmental Assessment #573 titled “Grand Isle and Vicinity, Louisiana Beach Erosion and Hurricane Protection Project” in Jefferson Parish, Louisiana for the New Orleans District. The purpose of this EA is to evaluate the potential impacts associated with the proposed construction of approximately five to ten stone, segmented breakwaters and the transport (via pipeline) and placement of dredged material to restore the existing beach and dune to project design standards on the west end of Grand Isle, Louisiana. The primary existing hurricane and storm damage risk reduction features of the project consist of a west end jetty at Caminada Pass; a vegetated sand berm and dune reinforced by a geo-textile dune with stone armoring located along the southern (gulf-side) shore of the Island; and segmented offshore breakwaters located on the east end of the Island. The purpose of the proposed actions is to provide additional stability and coastal storm damage risk reduction to the island and to restore the shoreline which has become severely degraded from wind and wave actions from the Gulf of Mexico and to help reduce future erosional impacts to the shoreline. This EA #573 has been prepared in accordance with the National Environmental Policy Act of 1969 and the Council on Environmental Quality’s Regulations, as reflected in the USACE Engineering Regulation ER 200-2-2. This EA #573 provides sufficient information on the potential adverse and beneficial environmental effects to allow the District Commander, U.S. Army Corps of Engineers, New Orleans District, to make an informed decision on the appropriateness of an Environmental Impact Statement or a Finding of No Significant Impact.
