Summary General text description of the levee system with a summary of why the levee is there, and the benefits it provides.

The East Jackson Levee System, located within Rankin County, Mississippi, was federally constructed in 1968 along the left descending bank of the Pearl River and provides risk reduction to the towns of Pearl, Flowood, and Richland. The levee system is approximately 13.5 feet tall and has an approximate length of 11.4 miles. The East Jackson Flood Control Project provides benefits to more than 10,000 people that work and live behind the levee, with more than $972 million in land and property value. The primary flood risk concerns are based on local storm runoff, with flooding on the Pearl River being the main source. Minor seepage (water penetrating through or under the levee) has been noted in isolated areas of the levee in the past, but none during the most significant high water events. The levee routinely performs well during yearly flood events with no breaches, including during the record flood of 1979.

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 is currently undergoing review and may be updated in the future. The major performance risk identified with the levee is failure due to the seepage issues observed during historic flood events. The USACE and the Levee District have a plan 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 leveed area lacks a flood warning system. . The Levee District maintains an Emergency Action Plan that includes notification of Rankin County, Hinds County, and affected municipalities’ Emergency Operations Centers. Flooding of the leveed area would also result in significant property losses and economic damages. The following table provides recommendations on how to improve on the potential risk drivers.
