Document Description
The proposed project will demonstrate technologies to reduce storm water runoff from dense mixed-use urban neighborhoods. The project will include construction of three or four "storm water gardens" in the parkways between the street and the sidewalks. The gardens will collect, treat, and infiltrate runoff from the residential properties, including driveways. The runoff will irrigate the gardens, while the gardens would remove contaminants from the storm water before it infiltrates the native soils below. The "streetend biofiltration" portion will divert and treat storm water that currently flows down Oros Street to an existing storm drain and then to the Los Angeles River. Storm water will be captured by two new catch basins specially designed to screen out debris and large particles. The water will then be conveyed via pipes to a subterranean infiltration gallery in Steelhead Park, where it will infiltrate to the undisturbed topsoil. It is anticipated that the proposed project will capture all the runoff from the design rain event (0.75 inch of rainfall in 24 hours); runoff that exceeds the capacities of the new catch basins would flow through the existing storm drains to the Los Angeles River.
