The project proposes the phased installation of an underground reinforced concrete pipe and a reinforced concrete box structure in order to adequately collect and convey the drainage flows of approx 704 tributary acres under a 100-year flood event. More specifically, the project involves the construction of a master drainage facility which would provide food protection to the existing Third St channel watershed and adjacent properties. Existing flood control improvements on the southern side of Coller Ave include an existing earthen trapezoidal channel aligned along portions of Third St beginning on the north side of Collier Ave. This initial study will analyze the potential environmental impacts associated with two phases of drainage improvements located primarily along Third St (phase 1 and 2 of proposed project) which will connect to the existing flood control improvements.
