This project will stabilize an existing stormwater outfall and rehabilitate the downstream drainage channel which conveys street and residential runoff and natural groundwater seepage. This project will involve extending the stormwater conveyance pipe, outfall energy dissipation and rehabilitation of the existing open channel. Multi jurisdictional regulatory review and approval will be a complicated and critical step in the successful design and construction of this project.
