Abstract:	The United States Army Corps of Engineers, Mississippi Valley Division, New Orleans District, has prepared this Individual Environmental Report #7 (IER #7) 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 (Figure 1), and includes three LPV reaches (109, 110 and 111) where approximately 13 miles of levees, floodwalls, and floodgates extending from South Point, south to the Gulf Intracoastal Waterway and west to the Michoud Canal Floodwall, would be modified to provide the 100-year level of risk reduction. Along with LPV 108 (which is located between Paris Road and South Point and is being raised to the previously authorized elevation that is equal to or greater than the 100-year level of risk reduction for this location), these reaches are locally known as the Lakefront to Michoud Canal 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 hurricane 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 109, 110 and 111) 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 flood protection which reduces the risk of hurricane surge and wave driven flooding that the New Orleans Metropolitan area has a one percent chance of experiencing each year.
