Former Campbell Shipyard Remediation


San Diego, California

Scope of Work:

  • Subsurface Evaluations
  • Extensive Background Searches
  • GIS
  • Close Coordination with Various Regulatory Agencies
  • Remedial Design and Oversight
  • Written Report

Approximately 9.2 acres of the 12.9-acre San Diego Unified Port District (District) leasehold at the former Campbell Shipyard, extending into San Diego Bay, required remediation to comply with Cleanup and Abatement Order (CAO) 95-21 issued by the California Regional Water Quality Control Board, San Diego Region (RWQCB).

Project Challenge: Ninyo & Moore assisted the District in sorting through several challenges, including negotiating cleanup levels that were protective of the District's interests, reducing the amount of soil requiring export/disposal, and control of emissions from remediation activities and waste stockpiles.

Innovative Solution: Various subsurface investigations were conducted by Ninyo & Moore in addition to a comprehensive compilation of historical aerial photographs and documents dating back to the 1800's. The data were entered into a Geographic Information System (GIS) database that allowed us to identify historical features associated with contamination, contamination source areas, the extent of contamination exceeding cleanup levels, and to potential responsible parties.

Ninyo & Moore was instrumental in working with the RWQCB to negotiate cleanup levels that were protective of the client's interests, which resulted in the approval on cleanup levels that would allow for the protection of the adjacent San Diego Bay while taking into consideration the proposed redevelopment plans for the site.

We also provided oversight of the remedial excavation activities to ensure the most efficient and cost effective methods were being utilized and to assist the remedial contractor with the segregation of clean and contaminated soil to reduce the amount of soil requiring disposal. We also assisted the District project manager in value engineering the earthwork portion of the Convention Center Parking Garage construction by reducing the amount of net export, which resulted in considerable savings to the District.

Services: Ninyo & Moore had been involved with the project since its inception in 1999. We managed and provided oversight and direction regarding identification, chemical characterization, delineation, and remediation of soil, groundwater, and off shore sediment contamination associated with a portion of a large former burn site, a former manufactured gas plant, a former tank farm, and Campbell Shipyard, which was under a CAO by the RWQCB. Contaminants of concern included polynuclear aromatic hydrocarbons, petroleum by-products, semi-volatile and volatile organic compounds, metals, and polychlorinated biphenyls (i.e., PCBs).
