Abstract: The U.S. Army Corps of Engineers, Mississippi Valley Division, New Orleans District, has prepared this Individual Environmental Report (IER) # 3 to evaluate the potential impacts associated with the proposed rebuilding of 9.5 miles of earthen levees, upgrading of the foreshore protection, the replacement of two floodgates, and the construction of fronting protection and construction or modification of breakwaters at four pumping stations as part of the Lake Pontchartrain and Vicinity Hurricane Protection Project. The proposed action is located in Jefferson Parish, Louisiana. For the purposes of this IER, the LPV area has been divided into numerous reaches, and each reach is identified by a project identification number. The purpose of the proposed action is to provide 100-year level of protection for Jefferson Parish East Bank. The proposed action results from the need to reduce flood risk and storm damage to residences, businesses, and other infrastructure from storm-induced and tidally-driven 100-year storm events in Lake Pontchartrain. The elevations of the existing floodwall tie-ins, gates, and levees within five reaches of the LPV project area (reaches 00, 01, 02, 19, 20) are below the 100-year design elevation. The completed GNOHSDRRS would lower the risk of harm to citizens, and damage to infrastructure during a storm event. The safety of people in the region is the highest priority of the CEMVN. The term “100-year level of protection” as 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 has a 1 percent chance of experiencing in any given year.
