Project Description
This project performed maintenance dredging in the Pittsburg Marina at Dredge Area A (Basin 3), Dredge Area B (Launch Ramp) and/or Dredge Area C (Residential Channel). The Work also included properly handling, transporting, and placing of the dredged sediment at the Carquinez Strait In-Bay Disposal Site (SF-9) and, the Montezuma Wetland Restoration Project (MWRP).
Major Challenges
One of the major challenges of this project is dredging the boat slips, dock sheds, and a narrow access channel within the marina. The confined nature of the work area, combined with the need to maintain navigation and access for the marina users, requires careful planning, specialized equipment, and close coordination with the stakeholders to execute the dredging operations safely and efficiently.
Project Highlights
A key project highlight was the opportunity to work closely with the owner and the local housing association to complete the project with the least amount of disruption to the marina and its users. By engaging with the stakeholders, the project team was able to develop and implement strategies that minimize the impact on the marina’s operations, ensuring the dredging work was carried out in a manner that was sensitive to the needs of the local community.
Project Scope
The City of Pittsburg through its agent, Anchor QEA, LLC (POC: Nicholas Duffort, Anchor QEA, LLC., 130 Battery Street, Suite 400, San Francisco, California 94565) has applied to the U.S. Army Corps of Engineers (Corps), San Francisco District, for a 10-year Department of the Army Permit to dredge approximately 457,000 cubic yards (cys) of sediment from the Pittsburg Marina (Marina) in Pittsburg, Contra Costa, California. The purpose of the proposed dredging is to return the Marina’s three basins and the Marina Park Residential Channel to its originally permitted depth to allow safe navigational depths for recreational boats. The applicant proposes to beneficially reuse the dredged sediment at the Montezuma Wetlands Restoration Project (Montezuma) or dispose of the dredged material at the Carquinez Strait Disposal Site (SF-9).
