Abstract: The U.S. Army Corps of Engineers, Mississippi Valley Division, Regional Planning and Environmental Division South, has prepared this Individual Environmental Report Supplemental 5.a (IERS 5.a) for the New Orleans District to evaluate the potential impacts associated with actions to occur on additional permanent and temporary Right of Way (ROW) in the construction of the permanent pump stations to be built at the 17th Street, London Avenue and Orleans Avenue outfall canals in Orleans and Jefferson parishes. This IER supplements the Government approved plan analyzed in Individual Environmental Report 5 (IER 5), Permanent Protection System for the Outfall Canals Project on 17th Street, Orleans Avenue, and London Avenue Canals, Jefferson and Orleans Parishes, Louisiana, which is incorporated by reference along with the Decision Record, signed 30 June 2009. IER 27 and IERS 27.a Outfall Canal Remediation on the 17th Street, Orleans Avenue and London Avenue Canals, Jefferson and Orleans Parish, Louisiana and their associated Decision Records, which were signed on 7 October 2010 and 15 April 2011 respectively, are also incorporated by reference. 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. The proposed action results from a defined need to reduce the risk of flood and storm damage to residences, businesses, and other infrastructure from storm-induced and tidally driven 100-year storm events in Lake Pontchartrain. The IER 5 impact assessment was based on the maximum anticipated footprints necessary for a typical conceptual design of a pump station that could handle the needed drainage and pumping capacity of each outfall canal permanent pump station. The Corps used a design-build delivery approach as the contracting mechanism to design and construct the pump stations. For more information on the design-build analysis, see IER 5, Section 1.6. Further design of the pump stations has resulted in refinement of additional project actions and the need for additional right-of-way (ROW) for some facilities and utilities associated with the pump stations.
