UPDATE: Interim Clean-Up Proposed as First Phase of Marina Center Development

On June 18th, 2009 the Regional Water Quality Control Board (RWQCB) approved a Supplemental Interim Remedial Action Plan (SIRAP). The SIRAP utilizes a multi-faceted approach for conducting interim remediation at the former Eureka Railyard including:

  • Debris and old structure removal, including foundations
  • Focused impacted soil excavation
  • Wetlands restoration and expansion
  • Site grading to eliminate storm water runoff

The intent of the SIRAP is to provide interim protection to both human health and the environment prior to the preparation and implementation of a Final Remedial Action Plan (RAP) for the site.


Ongoing surface water monitoring has indicated that water impacted with metals (primarily copper) discharges offsite on occasion during precipitation events. Based on this ongoing situation, the RWQCB requested that CUE VI take action to address the issue. In response to the RWQCB request, CUE VI submitted the SIRAP, which will be implemented upon receipt of all necessary permits.

When all the work is completed, the site will be beautified, surface drainage stabilized, and 11 acres of the site (including Clark Slough) will be restored to a pristine wetland complex as illustrated in the flyover.
