Bixby Marshland

Bixby Marshland

Did you know that, in addition to operating wastewater and solid waste facilities, the Sanitation Districts own and maintain a marshland? Yes, it’s true! The Bixby Marshland, a 17-acre marsh, located to the northwest of the Joint Water Pollution Control Plant (JWPCP) near the intersection of Figueroa Street and Sepulveda Boulevard in the City of Carson, has recently been restored by the Sanitation Districts.

What is a marshland?

A marsh is a wetland environment. It is a tract of soft, wet land usually containing grass or rushes. The Sanitation Districts’ marshland consists of various habitats that receive water from the Wilmington Drain. Wetlands are unique because of their role as an “ecotone”, or transition area, between terrestrial (land) and aquatic (water) environments.

How was the Bixby Marshland created?

The Bixby Marshland is a remnant of a formerly extensive, natural-freshwater wetland known as Bixby Slough. Over the years, most of Bixby Slough was destroyed due to development.

To restore the Bixby Marshland, the site was vegetated with a large number of native plants and regraded to improve the flow of water. A pump was installed to lift storm water and urban runoff from Wilmington Drain into the marshland. After going through the marshland, the water exits back into Wilmington Drain. Through this restoration effort, the site has been rejuvenated, renewing the marshland’s health and increasing its value to wildlife.

Why are wetlands important?

Wetland habitats are home to 43 percent of the federally-listed endangered and threatened species. They provide habitat for birds, animals, amphibians, invertebrates, fish, and a diverse group of plants.

Besides providing habitat, wetlands are sometimes called “the kidneys of the landscape” because they receive water that rushes off the land during storms. In the wetland, water is cleansed of sediments and pollutants before it slowly enters the ocean or underground aquifers.

When is the marshland open to the public?

The marshland is open the first Saturday of the month from 8 a.m. - 12 p.m. Docents are onsite to provide tours to those interested or self-guided tours are also available. Tours for groups may also be scheduled by appointment. To schedule a tour, please call (562) 908-4288, extension 2301.

Is it possible to volunteer at the marshland?
Yes, the Sanitation Districts are seeking volunteer docents to provide tours and educational programs at the Bixby Marshland.

Weekend and weekday opportunities are available, depending on the docent's schedule. We hope that docents will commit to help in one tour/education program per month (2 hours/month), but will appreciate any amount of time you have to offer.

If you are interested in participating as a docent, please call (562) 908-4288, extension 2308 or email:

Where exactly is the Bixby Marshland located

The entrance to the marshland is located on Figueroa Street, just south of Sepulveda Blvd, on the west side of the street. An iron gate, not far from the corner of Figueroa and Sepulveda, leads into the parking lot. From the 110 Freeway, exit Sepulveda and head east to Figueroa Street. Turn right on Figueroa Street and turn right into the marshland. Please also see the map.
