Abstract: The United States Army Corps of Engineers, Mississippi Valley Division, New Orleans District, has prepared this Individual Environmental Report (IER) # 8 to evaluate the potential impacts associated with the proposed improvement or replacement of a flood control structure on Bayou Dupre. The Hurricane and Storm Damage Risk Reduction System in the area of Lake Pontchartrain and Vicinity has been divided into numerous reaches, with each reach identified by a project identification number. The IER # 8 control structure comprises reach LPV 144.02, located where Bayou Dupre crosses the Chalmette Loop portion of the HSDRRS in St. Bernard Parish, Louisiana. The project area is located on the south bank of the Mississippi River Gulf Outlet, in the northwest portion of St. Bernard Parish. Dominant physiographic features in the vicinity include the drained and developed area between the Mississippi River and the Forty Arpent Canal, Mississippi River Gulf Outlet, Lake Borgne, and extensive marshes. The communities of Chalmette, Meraux, Violet, and others make up the area along the Mississippi River to be protected by the project. It is the intent of the CEMVN to employ an integrated, comprehensive, and systems-based approach to hurricane and storm damage reduction in raising the HSDRRS to the 100-year level of risk reduction. The term “100-year level of risk reduction,” as it is used throughout this document, refers to a level of risk reduction which reduces the risk of hurricane surge and wave-driven flooding that the New Orleans Metropolitan Area has a 1 percent chance of experiencing each year. The proposed action would satisfy the CEMVN’s purpose and need to provide the 100-year level of risk reduction from flood damage due to flooding from hurricanes and other tropical storms in the St. Bernard Parish area. The elevations of the existing drainage structure and levee tie-ins of the LPV project are below the 100-year design elevation. The proposed action resulted from a defined need to reduce flood risk and storm damage to residences, businesses, and other infrastructure from hurricanes (100-year storm events) and other high water events. The completed HSDRRS would lower the risk of damage to property and infrastructure during a storm event. The safety of people in the region is the highest priority of the CEMVN.
