No Data Summary
General text description of the levee system with a summary of why the levee is there, and the benefits it provides.
The Non-Federal Maxent Levee System is located in Orleans Parish, Orleans East Sub-basin of the New Orleans East Bank Levee System. The levee completes a secondary ring of the Hurricane and Storm Damage Risk Reduction System (HSDRRS) where a division between zoned wetlands and urban development occurs. The principal function of the levee segment is to reduce the risk to people and property for rainfall events by pumping water from populated areas into the adjacent wetlands. The levee segment is approximately 4.8 miles long and includes the earthen embankment with sod and the Orleans Parish #18 (Maxent) Pump Station.
The levee was completed in approximately 1953 and was authorized and constructed under the direction of the Orleans Levee District (OLD). Several utilities cross the levee and several residential and business areas abut the levee right-of-way.
Performance & Condition
General text description of the historical and anticipated performance of the levee, the people and property benefitting from the levee and who may be at risk of flooding, and actions to address areas of concern.
The Maxent Subarea Levee System is classified as Low risk. The primary risk driver is overtopping. The overtopping would likely occur during pumping operations which means that the overtopping flow would slowly increase providing less scour likelihood. There is a very low risk of breach prior to overtopping because the pumping station will be pumping water out of the leveed area. The leveed area should expect to see less than 1.5 feet of Inundation. Total population at risk is 50,000 during the day and 77,000 during the night. The population at risk appear to have some awareness of their risks while maintaining good flood warning effectiveness but lacking good evacuation plans.
