Blog – Case Study: Sierra Point Landfill
Have you ever dined at the DoubleTree Hotel? Or enjoyed a walk or run along San Francisco Bay Trail along the Brisbane Marina? Enjoyed a cocktail at the Yacht Club?
There’s not a second thought that we’re eating, drinking and enjoying the day on a former landfill. That’s because Sierra Point has gone through the rigorous remediation process to become the beautiful marina and successful office park it is today.
Sierra Point was used for the disposal of municipal solid waste from 1965 to 1972, not unlike the eastern portion of the Baylands site, which operated as a landfill until 1967. Following closure the site was redeveloped as an office park and a marina. Three of these buildings were constructed with pile foundations prior to the Loma Prieta Earthquake of 1989.
The property owners currently comply with requirements imposed by the Regional Water Quality Control Board (RWQCB) for correcting any problems associated with the former disposal site as it exists in it’s current uses or any subsequent use. On April 17, 1996, a Post-Earthquake Inspection and Corrective Action Plan for Sierra Point Landfill was prepared. The Plan would be implemented in the event of a Magnitude 7.0 or greater earthquake within 30 miles of the former landfill. The Plan specifies the property owners must:
- Implement the corrective action plan and the RWQCB must be notified of any damage immediately
- Report to RWQCD within 72 hours of the event the results of the inspection of containment features and groundwater and leachate control facilities potentially impacted by the static and seismic deformations of the landfill
- Assess perimeter dikes, the shoreline erosion protection measures and the surface locations of underground utilities
- Assess the landfill cover including roads and parking areas
- Check the groundwater and leachate monitoring systems, as well as surface-water drainage and outlet facilities
Similar to the office campus, restaurants and parks on Sierra Point’s former landfill, the former landfill on the Baylands site plans would have the same uses in addition to retail and renewable energy, as indicated in the orange circle within the image below. This portion of the development would also fall under the regulatory oversight of the RWQCB, and once land uses have been determined for the area, a Remedial Action Plan will be developed and submitted to RWQCB for their approval prior to any development.
The City of Brisbane created a Landscape and Lighting District, a financing mechanism to install and maintain public landscaping and lighting facilities for Sierra Point in which all the property owners are assessed annual fees. UPC will pursue similar maintenance districts to finance the cost of maintaining the 305 acres of open space planned for the Brisbane Baylands.
