Wilmington Drain Multi-Use And Machdo Lake Ecosystem Rehabilitation (Archived)

The City is proposing to rehabilitate the Wilmington Drain and Machado Lake located adjacent to and within the Ken Malloy Harbor Regional Park (located at 25820 Vermont Avenue) in the communities of Wilmington and Harbor City, CD 15. The Machado Lake ecosystem, which includes Wilmington Drain, has been negatively impacted by trash, proliferation of invasive plant species, eutrophication, and sediment and nutrient accumulation, which has resulted in degraded water quality, fish and wildlife habitat, and hydraulic capacity. To address these problems, the City is proposing to implement a variety of measures designed to improve water quality; help meet adopted and future total maximum daily loads criteria; enhance riparian, wetland, and upland habitats; improve hydrologic and hydraulic conditions; and restore existing recreational amenities as well as develop new ones.

The City prepared a draft environmental impact report (EIR) to analyze the environmental impacts of the proposed project and alternatives and is requesting input from responsible agencies, trustee and other interested parties. The notice of availability and the draft EIR can be viewed from the links below and is available for review at Harbor City/Gateway Library, 24000 S. Western Avenue; Wilmington Branch Library, 1300 N. Avalon Boulevard; Harbor District Office No. 15 at 638 S. Beacon St., Suite 552, San Pedro; and the Bureau of Engineering, EMG at 1149 S. Broadway, 6th Floor, Contact: Maria Martin at (213) 485-5753, fax: (213) 847-0656.
