Summary General text description of the levee system with a summary of why the levee is there, and the benefits it provides.
The levee system is part of the Mississippi River and Tributaries (MR&T) project. The MR&T project was authorized by the 1928 Flood Control Act. In the wake of the devastating 1927 flood, it was deemed necessary to put into place a comprehensive, unified system of public works within the lower Mississippi Valley that would provide unprecedented flood risk management and an equally efficient navigation channel. The MR&T project continues to be one of the world’s most comprehensive and successful flood risk reduction projects.The West Bank Mississippi River Levee (MRL) System begins at Pine Bluff, Arkansas and continues south into the New Orleans District. The system is comprised of 5 different segments. The first three segments are along the Arkansas River and are approximately 85 miles of levee. The remaining segments are along the west bank of the Mississippi River and are approximately 274 miles of levee. The levee system is approximately 360 miles of levee, protecting approximately 6900 square miles of mostly agricultural land. The estimated population is approximately 233,000 people with a property value of $21 Billion. Levees in this system have numerous landside berms to help control seepage. Select areas have relief wells at various intervals located at the landside toe of levees where berms could not be constructed or where constructed berm was not sufficient to help control seepage.
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.
PLEASE NOTE: The following Risk Characterization is a description of risk associated with this levee system. It may be updated or revised in the future. The major performance risk identified with the levee system is failure due to the seepage issues observed during historic flood events. The USACE and the Levee Districts have plans to address seepage issues as they occur and past efforts to “flood fight” seepage issues have been successful. However, the presence of seepage issues can increase the risk of a levee failure. A levee failure due to seepage would occur suddenly, which reduces the time to warn people and evacuate the area. A reduction in warning time may increase the likelihood of property damage and human fatalities. The area behind the levee lacks specific flood warning systems. Each levee district in Louisiana maintains an Emergency Action Plan (EAP). The EAP for this levee system includes the notification of East Carroll, Madison, Tensas, and Concordia Parishes, and affected municipalities’ Emergency Operations Centers. Flooding of the leveed area would result in significant property losses and economic damages. The Arkansas levee sponsors don't have EAP's, but they are flood aware and they have flood fight experience.
