Current Project Updates


Cleanup activities are complete at the Larkspur Landing former treatment plant site, as required by the U.S. EPA. As of October 4, 2021, RVSD is waiting for the U.S. Environmental Protection Agency (EPA) to officially approve the cleanup of the Larkspur Landing property. 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 consulting 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.


The District is conducting a series of special board meetings as informational presentations about options for surplus property disposition at its former wastewater treatment plant site at 2000 Larkspur Landing Circle. To provide the Board of Directors and the public with a recap of these meetings, the District held a special board meeting on Wednesday, October 13, from 5 - 7 p.m.

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, 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.


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. RVSD continues to wait for the U.S. EPA's official signoff of the site cleanup of the former wastewater treatment plant site. 


Over the past year, the District has conducted a series of informational presentations relating to a potential surplus property disposition in the future. More information about each meeting is provided under the Informational Presentation headings that follow below.
