Document Description
The Seabreeze Marina Tunnel Sealing and Wetland Enhancement Project (project) involves a combination of remediation and habitat enhancement elements which will take place at the project site within approximately the same time frame. The project site is located at the Seabreeze Marina (also known as Clinton Basin), at the west end of Sixth Avenue, between the Embarcadero and the Oakland Esturary. The site is approximately 7 acres in size. The Port proposes to remediate and close two remnant, underground tunnels that previously transported cooling water to and from a former power plant at the project site. The two tunnels extend from the northern portion of the site to the southwest and northwest shoreline areas, respectively. Tunnel remediation would include the excavation of some contaminated material inside the tunnels, and the sealing of the tunnels approximately 50 feet from the shoreline to prevent the potential for the discharge of contaminants contained in the tunnels to surface waters. In addition, the Port is proposing a plan for habitat restoration and wetland enhancement at the project site, along the beach on the southwest side of the site. Wetland enhancement activities would include the creation of a tidal channel, the creation of a tidal marsh and the enhancement of roosting areas for shore and water birds.
