dc.description.abstract | The U.S. Army Corps of Engineers, Mississippi Valley Division, New Orleans District has prepared this Individual Environmental Report # 2 (IER # 2) to evaluate the potential impacts associated with the proposed replacement of 17,900 feet of floodwalls as part of the Lake Pontchartrain and Vicinity Greater New Orleans Hurricane and Storm Damage Risk Reduction System, formerly known as the Hurricane Protection System. The proposed action is located on the border of Jefferson and St. Charles Parishes, Louisiana. The purpose of the proposed action is to provide a 100-year level of flood protection for Jefferson and St. Charles Parishes. The proposed action results from a defined need to reduce flood risk and storm damage to residences, businesses, and other infrastructure from hurricanes (100-year storm events) and other high water events. The elevations of the existing drainage structures and the LPV project levee tie-ins are currently below the 100-year design elevation. The safety of people in the region is the highest priority of the CEMVN. The completed GNOHSDRRS would lower the risk of harm to citizens, and damage to infrastructure during a storm event. The term “100-year level of protection,” as it is used throughout this document, refers to a level of protection which 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. | en_US |
