| dc.description.abstract | The U.S. Army Corps of Engineers, Mississippi Valley Division, New Orleans District, has prepared this Individual Environmental Report Supplement (IERS) # 8,9,10.a to evaluate the potential impacts associated with the proposed modification to flood protection improvements to the Lake Pontchartrain and Vicinity Hurricane and Storm Damage Risk Reduction System in Orleans, St. Bernard, and Plaquemines Parish, Louisiana. The CEMVN initially evaluated the potential impacts associated with constructing the selected plans for HSDRRS around the Chalmette Loop area of the Lake Pontchartrain and Vicinity in three IERs. A Decision Record for IER #8 titled Lake Pontchartrain and Vicinity, Bayou Dupre Control Structure, St. Bernard Parish, Louisiana was signed on June 23, 2009. IER #8 evaluated the potential effects associated with the construction and improvement of a flood control structure on Bayou Dupre (LPV 144.02). A Decision Record for IER #9 titled LPV, Caernarvon Floodwall, St. Bernard Parish, Louisiana was signed on February 8, 2010. IER #9 evaluated the potential effects associated with construction of a new floodwall alignment to the west of the Caernarvon Canal to replace the existing Caernarvon Floodwall (LPV 149). A Decision Record for IER #10 titled LPV Chalmette Loop Levee, St. Bernard Parish, Louisiana was signed on May 26, 2009. IER #10 evaluated the potential effects associated with raising the Chalmette Loop Levee reaches LPV 145, LPV 146, LPV 147, and LPV 148.02 to the 100-year level of risk reduction. These original IERs are incorporated by reference into this IERS 8,9,10.a. Copies of the documents and other supporting information are available upon request or at www.nolaenvironmental.gov. To evaluate the potential impacts for a design change to the original Chalmette Loop T-wall project, the CEMVN is preparing this IERS #8,9,10.a entitled “Lake Pontchartrain and Vicinity, Bayou Dupre Control Structure, Caernarvon Floodwall and Chalmette Loop, Orleans, St. Bernard, and Plaquemines Parishes, Louisiana." The proposed modification described in this supplement pertains to enabling operation and maintenance access for the LPV 145a, LPV 145 – LPV 149 reaches and a tie-in to the Mississippi River Levee. | en_US |
