| dc.description.abstract | The U.S. Army Corps of Engineers, Mississippi Valley Division, New Orleans District, has prepared this Individual Environmental Report # 16 (IER # 16) to evaluate the potential impacts associated with the proposed construction and maintenance of the 100-year level of hurricane damage risk reduction along the West Bank and Vicinity, Western Terminus Flood Damage Reduction Project Area. The term “100-year level of risk reduction,” as it is used throughout this document, refers to a level of protection that reduces the risk of hurricane surge and wave-driven flooding that the New Orleans metropolitan area experiences by a 1 percent chance each year. The proposed action is located in Jefferson and St. Charles Parishes near New Orleans, Louisiana. The approximate project-area boundaries are South Kenner Road on the east (Jefferson Parish); the Davis Pond Freshwater Diversion Project Canal on the west (St. Charles Parish); South Kenner at the Union Pacific and Burlington Northern Santa Fe (BNSF) Railroad Lines and the Mississippi River on the north, and the Outer Cataouatche Canal and Davis Pond to the south. Communities near the project area include Avondale and Waggaman to the east, Ama and South Kenner to the north, and Luling to the west. With the exception of landfills on the eastern portion of the project area, much of the study area remains undeveloped. The 1996 Westwego to Harvey Canal, Louisiana, Hurricane Protection Project, Lake Cataouatche Area, Post Authorization Change Report and Environmental Impact Statement (USACE, 1996) approved the western tie-in north of Highway (Hwy) 90 along South Kenner Road and ending at the elevated Southern Pacific Railroad. Although approved for completion, the western tie-in was never constructed due to limited funding. | en_US |
