STATEMENT OF THE
ISSUE:
On April 19, 2022, the City Council approved a sole-
source contract with COWI North America, Inc. to

AGENDA
REPORT

DISCUSSION:
The City has been planning the removal of the creosote-treated piles and deteriorated wharf decking and structures at the Terminal Four site for a number of years. The State Coastal Conservancy (SCC) has provided support and assistance with this project since 2017, primarily through facilitating funding and taking the lead on early design and environmental review. In June 2019, COWI North America, Inc. (COWI) completed the 60% design and specifications for the project under contract with the SCC.
The City will be carrying out implementation of the Terminal Four Wharf Removal Project as the property owner. On April 19, 2022, the City Council approved a sole- source contract with COWI to take their previously prepared 60% design and complete the final construction and technical specifications for the bid documents for this project.
The goal is to start demolition work this June 2023. The bid documents were recently posted and City staff is seeking a first contract amendment with COWI to provide engineering services during the bid phase and next phase of work, construction, plus services needed to complete the Final Plans and Specifications.
Terminal Four Wharf Removal Project
The Terminal Four Wharf Removal project consists of completing construction documents, demolishing derelict pilings, decking, and two buildings, and constructing enhanced rock slope protection and monitoring at Terminal Four located at Point San Pablo, north of Point Molate.
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 will remove toxic creosote pilings from San Francisco Bay. The Terminal Four site is owned by the City of Richmond and is managed by the City’s Port. 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.
The proposed contract amendment would cover COWI support in the bid evaluation process, as well as during construction. This work includes:
Participating in regularly scheduled status meetings. Reviewing and responding to contractor submittals.
