Abstract: The U.S. Army Corps of Engineers, Mississippi Valley Division, New Orleans District, has prepared this Individual Environmental Report # 33 (IER # 33) to evaluate the potential impacts associated with the proposed construction and maintenance of the 100-year level of hurricane damage risk reduction along the West Bank and Vicinity – Mississippi River Levee (WBV-MRL) Co-Located Project. The MRL on the west bank of the Mississippi River, from the Eastern Tie-in of the West Bank and Vicinity (WBV) project with the MRL at Oakville in Plaquemines Parish to a point approximately 15.5 miles upriver southeast of the Algiers Lock in Orleans Parish, is not of sufficient height to provide 1 percent hurricane and storm damage risk reduction. The terms “100-year level of risk reduction” and “1-percent level of risk reduction” as they are used throughout this document, refer to a level of risk reduction that reduces the risk of hurricane surge and wave-driven flooding that the New Orleans metropolitan area experiences to a 1 percent chance each year. The WBV-MRL Co-Located Project is designed to reduce risk to residents along the west bank of the MRL from hurricane-driven storm surges traveling either up or across the Mississippi River. The proposed action is located in Plaquemines and Orleans Parishes on the west bank of the Mississippi River and is part of the West Bank and Vicinity (WBV) Belle Chasse Polder, New Orleans, Louisiana. The project area extends from river mile 85.5 to 70 Above Head of Passes (AHP). The northern end (river mile 85.5) is situated near the intersection of Patterson Road and Delacroix Road in English Turn and the southern end (river mile 70) is approximately 525 feet south of the intersection of East St. Peter Street and the Mississippi River Levee at Oakville. The existing MRL levee alignment has been divided into five contract reaches of varying lengths; figure 2 illustrates the locations of the five contract reaches and table 1 identifies their lengths and average deficiencies. Note that the project originally was divided into seven reaches, but reaches 2.1 and 5.1 were combined into reaches 1.1 and 4.1, respectively.
