Discussion

The State of California Department of Health Services and Department of Toxic Substances Control (DTSC) has worked with the City of Richmond since 1987 on environmental site characterization and remediation efforts within the Marina Bay Project. The Marina Bay Project encompasses approximately 200 acres (excluding waterways and private rights-of-way) along the San Francisco Bay shoreline. Much of the area was originally a tidal mudflat and salt marsh. Santa Fe Land Improvement Company (Santa Fe) acquired the property in 1941. Between 1941 and 1947, Santa Fe leased the site to the Richmond Shipbuilding Corporation and Permanente Corporation, later known as the Kaiser Aluminum and Chemical Corporation (Kaiser). Construction of the shipyard began in 1941 and entailed substantial dredging of native bay mud to deepen the Richmond Marina Bay for use as a launching basin and filling the remaining portions of the site with dredged material and imported fill. Under contract to the United States Government, Kaiser constructed cargo and transport ships at the shipyard during World War II.

The shipyard closed in the late 1940s, and Santa Fe subsequently leased many of the shipyard buildings and various parcels of land within Marina Bay for warehousing, manufacturing, sand storage, concrete pre-casting, and other industrial uses. In 1977, the City purchased the site from Santa Fe. The property was subsequently divided into approximately 30 parcels on the West, North, East and South shores of the site for residential and commercial development.

The City of Richmond and developers conducted environmental investigations and implemented remedial investigations through the Marina Bay Project with oversight by DTSC. The City is responsible for nine discrete areas within the Marina Bay Project, for which it is responsible for implementing the requirements of environmental deed restrictions emplaced due to the presence of encapsulated or residual contamination following completion of remedial activities. The origins of the contamination are primarily the historical shipbuilding activities conducted at the project site.

Beginning in the 1980s, various environmental investigations were conducted to characterize the extent of contamination at the Marina Bay Project site and facilitate its redevelopment. On November 23, 1987, the Mayor approved a $45,000 Oversight Agreement for the Richmond Marina Bay Project with the State Department of Health Services. These early investigations ultimately culminated in the preparation of the Final Restoration Advisory Plan (RAP), which established the decision-making framework for remedial actions within each of the nine deed-restricted areas.

In December 2025, DTSC contacted the City of Richmond that it would need an updated agreement, a Standard Voluntary Agreement (SVA), and as well as the City’s nine-deed restricted areas that will be contained in this SVA that there are two areas within the Marina Bay Project, Areas FF and O, that are now privately owned but DTSC would like an agreement with City in order to also perform basic environmental oversight work on those two parcels (Attachment 1).

City staff are requesting authorization for the City Manager to enter into a SSVA) with the DTSC for the environmental oversite of the City of Richmond’s nine deed-restricted properties and two privately owned properties of Areas (Attachment 2).
