Oxford Basin

Oxford Basin is a constructed wetland located between Washington Boulevard and Admiralty Way that manages stormwater from the surrounding urban area. The site includes viewing platforms, walking paths, and planted areas with native vegetation.

The site came about when the Marina del Rey harbor was developed in the 1950s and a former landfill was converted into a water management system. This transformation later protected surrounding neighborhoods from flooding.

The site serves as a place where people learn about wetland ecosystems through interpretive displays and guided walks along its pathways. Visitors can observe how water and wildlife interact in this restored environment.

The area is easy to walk around with designated pathways and has parking available at nearby park and beach lots. It is best visited during daylight hours when the viewing areas are fully accessible.

The basin attracts numerous bird species and supports plants that are essential for monarch butterfly reproduction. These butterflies pass through the region during their annual migration.
