Title

Oxford Retention Basin Multiuse Enhancement Project

Description

The current discretionary action for the Oxford Basin Multiuse Enhancement Project, approved by the Los Angeles County Board of Supervisors, the governing body of the Los Angeles County Flood Control District, on March 10, 2015, includes approval of plans and specifications; advertising the project for construction bids; delegate authority to award a construction contract for the project; and adopt a resolution to authorize a grand funding agreement with the California Department of Water Resources. The project was previously approved by the Board of Supervisors on December 3, 2013 and a Notice of Determination was filed on that date. The current discretionary approvals are included in the scope of impacts analyzed in the previously adopted MND. The proposed project consists of improvements to flood control infrastructure, water quality, wildlife habitat, aesthetics, and recreational opportunities at Oxford Retention Basin. The project includes, but is not limited to replacing existing tide gates; excavating accumulated sediment from the bottom of the basin; removing contaminated soils along the basin perimeter and replacing it with clean imported fill; removing and replacing existing fencing; retrofit existing catch basins; constructing a new 2-foot high concrete parapet wall along the basin's northern and western rim, a new vegetated circulation berm, bio-retention systems, maintenance access ramps, observation areas, a walk/jog path with wildlife-friendly lighting, benches, trash receptacles, and interpretive signage around the performer of the basin; removing and replacing existing vegetation, including removal of approximately 650 trees and replacement with over 650 trees.
