West Bank Mississippi River Levee, New Orleans to Venice NOV-09 St. Jude to City Price

The Mississippi River Levees (MRL) is an integral part of both the Lake Pontchartrain and Vicinity (LPV) and West Bank and Vicinity (WBV) hurricane systems. For some reaches of the river, the HSDRRS and the MRL coincide, meaning they serve a dual purpose of reducing risk from riverine and hurricane surge flooding. Some reaches of the river levees are “co-located,” meaning that the required levee grade to minimize the risk from the storm surge that has a one percent chance of occurring in any given year is higher than the levee grade needed to reduce risk from a riverine event. Approximately 15.5 miles of co-located levees sit within the WBV Belle Chasse polder from River Mile 70 to River Mile 85.5.
