| Abstract: | The U.S. Army Corps of Engineers, Mississippi Valley Division, New Orleans District, has prepared this Individual Environmental Report Supplemental #16.a (IERS #16.a) to evaluate the potential impacts associated with the proposed project revisions to the original IER #16 project West Bank and Vicinity, Western Tie-In Project Area. Since IER #16 was completed, the preliminary project feature designs have undergone revisions. This IER Supplemental contains changes to the original plan including: a. utilities relocations, b. the relocation of Highway (Hwy) 90 Pumping Station, c. installing bank stabilization to closures across the Outer Cataouatche Canal, d. converting temporary bypass roads to permanent access for Hwy 90, and e. construction of a ramp at Hwy 18, River Road, instead of a floodgate. Comments received during the public comment period for the original IER #16 recommended that the proposed gate feature not be constructed across Hwy 18 because the gate would hinder the use of Hwy 18 during evacuation events. Additionally State of Louisiana and local transportation, safety and law enforcement personnel raised similar concerns about the closure of Hwy 18 during storm events if a gate was constructed at Hwy 18. 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. The proposed action is located in Jefferson and St. Charles Parishes near New Orleans, Louisiana. |
