Richmond Field Station Marsh Remediation and Restoration

The University of California, Berkeley is working with the California Regional Water Quality Control Board to implement a cleanup and restoration plan for contaminated areas of UC Berkeley’s Richmond Field Station (RFS) and Stege Marsh. Historic industrial activities that took place prior to UC ownership of the site polluted parts of the property and the adjacent marsh. The University’s goal for the area is to clean up, enhance, and restore the shoreline and habitat in the marsh.

Project Fact Sheet

The clean up, or remediation, of contaminated areas of the marsh includes excavation of contaminated soil, backfill with clean soil, and grading. This work at the RFS has been scheduled to take place in the fall to minimize affects to wildlife living in the Marsh, including the endangered California Clapper Rail. Remediation managed by UC Berkeley is being done in phases. Work in the West Stege Marsh took place during 2002 fall/2003 winter and 2003 fall/2004 winter. Remediation activities are scheduled for areas in the RFS Uplands starting in fall 2004. Additional work is proposed for Meeker Slough in fall 2006.

Restoration of West Stege Marsh began in 2003 and will continue for the next few years. The work includes planting native species, weed removal, trapping feral animals, and long term monitoring of the area.

A Little Background:
The remaining section of old pier at the RFS part of the wharf built in the mid 1800’s for transport of grain from Rancho San Pablo to San Francisco to feed the horses used for transportation there. It was subsequently used by Mr. Stege to transport frogs to SF restaurants. From 1877 to 1948 it was used by the California Blasting Cap Company. As it decays, the wood provides habitat for small ecosystems in the marsh. The Bay Trail sits on top of a berm that was a part of a railroad system built in 1959. The addition of this berm changed the tidal mudflats into a muted tidal marsh inhabited by native cordgrass and pickleweed. These plants provide habitat for endangered species like the California Clapper Rail and the Salt Marsh Harvest Mouse. The University’s restoration work is focused on recreating this habitat.
