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 located along the east bank of the Connecticut River and the north bank of the Hockanum River in East Hartford, CT and is intended to reduce flood risk to portions of the Town of East Hartford, CT. The levee system was constructed by the US Army Corps of Engineers in response to devastating floods that occurred in 1936 and 1938. Construction of the levee began in December 1938 and was completed in July 1943. The levee system extends from high ground near Greene Terrace at is northern end to high ground near Brewer Lane and Central Avenue to the south. The levee consists of 19,300 feet of earth embankment, 1,400 feet of concrete floodwall, two stop-log closure structures, and three pump stations. These structures work collectively to reduce flood risk to approximately 760 acres of mixed residential, commercial, and industrial properties. The system is federally authorized and constructed and locally operated and is maintained by the Town of East Hartford, CT.
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.
In 2014, USACE performed an evaluation of the levee system aimed at understand the risk to those living and working behind the system. Results of that analysis show that the levee is likely to withstand water to the top of the levee without breaching. However, there has not been a flood event that has loaded the system more than 75% of its capacity. It is important to note that breach is possible. A breach in the system could result in inundation depths of over 24 feet and could result in over $360 million in damages and loss of life. Currently there are significant sections of the toe drain systems that are in poor condition. As a result, there are some uncertainties with how the system will perform during a flood event.
