Abstract:	U.S. Army Corps of Engineers, Mississippi Valley Division, New Orleans District, has prepared this Individual Environmental Report #6 (IER #6) to evaluate potential impacts associated with proposed improvements to three reaches of the East Orleans Hurricane Protection Levee that were originally constructed as part of the Lake Pontchartrain and Vicinity project. The proposed action is located in the New Orleans East area of Orleans Parish, Louisiana, and includes three LPV reaches (105, 106, and 107) where approximately 6 miles of levees, floodwalls, and floodgates extending from the Inner Harbor Navigation Canal and New Orleans Lakefront Airport east to Paris Road would be modified to provide the 100-year level of risk reduction. Combined, these reaches are locally known as the Citrus Lakefront Levee. The purpose of the proposed action is to provide 100-year level of risk reduction for New Orleans East. The proposed action results 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 in Lake Pontchartrain. Elevations of the existing floodwalls and levees within three reaches of the LPV project (reaches 105, 106, and 107) are below 100-year design elevations and do not meet CEMVN design criteria. The proposed action is needed to meet the 100-year design elevations and design criteria in these three reaches. 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 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.
