Abstract:	The U.S. Army Corps of Engineers, Mississippi Valley Division, New Orleans District, has prepared this Individual Environmental Report #5 (IER #5) to evaluate the potential impacts associated with the construction and maintenance of a permanent protection system for the 17th Street, Orleans Avenue, and London Avenue Canals. The proposed action discussed in this document is in the New Orleans metropolitan area in Jefferson and Orleans Parishes. The purpose of the proposed action is to reduce the risk to the City of New Orleans and Jefferson Parish from storm surge-induced flooding through the 17th Street, Orleans Avenue, and London Avenue Outfall Canals, while not impeding the ability of the area’s internal drainage system to function. Public Law 109-234 states for the USACE to “…modify the 17th Street, Orleans Avenue, and London Avenue drainage canals and install pumps and closure structures at or near the lakefront.” The overall need of the HSDRRS project is to provide a comprehensive, integrated protection system that would prevent storm surge-induced flooding via the outfall canals and reduce the imminent and continuing threat to life, health, and property posed by flooding from hurricanes and other tropical storm events. The proposed action results from a defined 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 purpose and need would be achieved by providing a 100-year level of hurricane protection. The completed HSDRRS 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 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 has a 1 percent chance of experiencing each year.
