In June 2016, PG&E successfully completed soil removal activities at the site of a former gas holder, located at 675 Jefferson Avenue in downtown Redwood City (site). All work was performed voluntarily with oversight from the California Department of Toxic Substances Control (DTSC).
PG&E restored planter areas upon completion of cleanup activities.
Cleanup activities included the removal and off-site disposal of impacted soil in planter bed areas. Crews backfilled excavations with clean material and restored the site with new landscaping.
As part of PG&E's commitment to safety, all work was performed in accordance with a project-specific Health and Safety Plan. PG&E will continue to work closely with the site owner as they implement a deed restriction for the site and will also work with the site owner to regularly inspect and maintain the asphalt that serves as a protective cover over the remaining impacted soil.
Community members receive advance notice of site milestones through work notices, door-to-door outreach and other activities, as appropriate.
Built in the early 1900s, the gas holder stored manufactured gas and, later, natural gas from 1914 to 1959. Since then, the site has been redeveloped into a bank and an associated parking lot.
