The project replaced existing levee underseepage control features. Twenty one original relief wells were replaced with a pervious toe trench with collector pipe system. The pervious toe trench is supplemented with a sand berm. The sand berm was partially constructed utilizing existing sand berm material on-site placed during the 2011 flood.
The project also rehabilitated the existing 6th Avenue Pump Station gravity storm drainage pipe utilizing slip lining practice. Additionally, gas and power infrastructure levee encroachments were relocated or removed for the benefit of the levee system.
