The work will involve removing trees, replacing the basin’s outlet structure, installing an automated valve on the outlet structure, constructing a retaining wall, replacing inlet pipes and constructing forebays, rebuilding an embankment, establishing a bypass channel, filling a headcut, excavating a new step-pool and riffle-pool stream channel, rerouting a pedestrian trail, and installing pedestrian bridges. The work will include providing traffic control and pedestrian safety around the work area during all phases of the project. Also, the work will include providing and maintaining erosion and sediment control as per the State- and City approved erosion and sediment control plan.
