The project consists of widening and deepening 1,290 feet of Cady Marsh Ditch; constructing 6,400 feet of 10-foot diameter pipe under Arbogast Avenue; improving 1,300 feet of open channel that leads into the Little Calumet River, and an interior drainage system including an upgrade of an existing pumping station and adding concrete culverts with flap gates. Construction of the underground tunnel system caused the least amount of disturbance to existing utilities, roads, and properties as compared to using the standard open cut construction technique. Two acres of wetland mitigation is required due to the loss of wetland because of constructing the tunnel outlet.
