Summary:

This project consists completing construction documents, demolishing derelict pilings, decking, and two buildings, and constructing enhanced rock slope protection, and monitoring at Terminal Four near Point San Pablo in Contra Costa County. 

The project is needed because the deteriorating warehouse, piles, decking, and debris of the Terminal Four Wharf currently pose a marine debris problem and a navigation hazard, and also continue to degrade and impair water and habitat quality. The existing debris and pile field inhibit the expansion of nearby eelgrass beds. When Pacific herring and other fish and marine invertebrates spawn on creosote-treated piles, exposure to polyaromatic hydrocarbons (PAHs), which are part of the creosote compound, results in adverse effects. In Pacific herring, these effects include developmental delays, degeneration, changes in movement, alterations to cardiac function in embryos, lower rate of hatching success, and skeletal defects in larvae.

This project is a priority for the Authority and was selected in competitive Grant Round Four because it will remove toxic creosote pilings from San Francisco Bay, a key priority identified in the Subtidal Habitat Goals Report. The Terminal Four site is owned by the City of Richmond  and is managed by the City’s Port Operations Department. The site is located on the western shore of Richmond, California, about 2.5 miles northwest of the eastern end of the Richmond-San Rafael Bridge, and just south of the tip of Point San Pablo.

While the primary ecological benefits will result from removal of the derelict structures and debris, the innovative living shoreline component of the project will provide additional habitat benefits. The experimental design for the enhanced rock slope includes a pilot “green-grey hybrid” approach that is being tested for the first time at this site to enhance biological habitats on a traditional rock rip rap revetment.
