Since construction completion of the levee system, maintenance of the levee and its appurtenances has been minimal. As a result, the waterside and some sections of the landside of the levee system exists with heavy vegetation and tree overgrowth that appears to impact the levee.

At the landside of the embankment, a toe berm was constructe…
