 The property's history goes back more than 100 years when it became home to a succession of chemical manufacturing companies, most notably Stauffer Chemical Company and, lastly, Zeneca, Inc. Manufacturing operations ceased in 1997 and an environmental cleanup was initiated under the oversight of the San Francisco Bay Regional Water Quality Control Board (RWQCB).In late 2002, Cherokee Simeon Venture I, LLC (CSV) acquired the property from Zeneca and continued the cleanup work.In 2005, regulatory oversight of the Campus Bay investigation and cleanup was transferred to the California Department of Toxic Substances Control (DTSC).
