Current Project Updates


Cleanup activities have been completed at the Larkspur Landing former treatment plant site, as required by the U.S. EPA. Now that the cleanup project is wrapping up, the District is embarking on the next phase of the property disposition, which includes a series of special board meetings as informational presentations described further below.


The District selected Century Urban to provide real estate consultant services to help develop a schedule and plan to engage the public and the City of Larkspur about this unique site which is located across the street from Marin Country Mart and near the Larkspur Ferry Terminal and Larkspur SMART station.


On March 17, 2021, the District adopted a Communications and Engagement Strategy for the potential disposition of the property after the U.S. EPA approves the cleanup.


Project Background


Ross Valley Sanitary District (RVSD) began clean up its 10.7-acre former wastewater treatment plant site at 2000 Larkspur Landing Circle in summer 2019 and completed the work on September 9, 2020. The property contained trace concentrations of polychlorinated biphenyls (PCBs) which was present in some of the paint that was applied to the concrete administration buildings. The concrete of the former plant was crushed and used as backfill back in 1999.


In March 2019, US EPA approved the remedial action plan to safely remove and dispose of this material, and in May 2019, RVSD selected a contractor to conduct the cleanup work. Site cleanup consisted of removal of about 64,000 tons of soil and demolition debris to a municipal landfill and removal of about 2,600 tons to a hazardous waste landfill. The site has been cleaned to the cleanest levels that enable unrestricted use of the property. Excavated areas have been back-filled with clean soil, with topsoil and hydro seeding. 


The cost of construction, engineering and permitting for this cleanup has been approximately $9.5M since 2018, and $10M in total. On January 15, 2021, RVSD submitted the draft site cleanup completion report to U.S. EPA for their comment, and when the final revised report is accepted by the U.S. EPA, the site will be officially available for consideration of the appropriate unrestricted land use.
