Current Project Updates


Cleanup activities are complete at the Larkspur Landing former treatment plant site, as required by the U.S. Environmental Protection Agency (EPA). On December 14, 2021, EPA approved the cleanup of the Larkspur Landing property for unrestricted land use, meaning that the property is suitably clean for all potential land uses with no exceptions. 

EPA approval also allows the District to continue with community outreach to help determine future uses of the property. You can view the District news release announcing EPA clearance here.

Project Background


Ross Valley Sanitary District (RVSD) began clean up of 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 were present in some of the paint applied to the concrete administration buildings. The concrete of the former plant was crushed and used as a 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 a level that enables unrestricted use of the property. Excavated areas have been back-filled with clean soil, with topsoil and hydroseeding.

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. Now that the final revised report has been accepted by the U.S. EPA on December 14, 2021, the site is officially available for consideration of the appropriate unrestricted land use.

On March 17, 2021, the District adopted a Communications and Engagement Strategy for the potential disposition of the property.
