Oakland Harbor Turning Basins Widening Navigation Study

Key Updates:

Background: The existing federal navigation turning basins in the Oakland Harbor, most recently improved circa 2008, were designed for a 6,500 twenty-foot equivalent units (TEU) capacity vessel with a 1,139-feet length overall. Vessels routinely calling Oakland today are larger, and in particular longer, than this design vessel. Vessels calling Oakland with lengths greater than 1,139-feet have transit restrictions resulting in inefficiencies and negative economic impacts.

Proposed Project: Widen both Oakland Harbor turning basins to accommodate a design vessel with a capacity of 19,000 TEU and length of 1,310-feet

Timeline: The feasibility study planning process for turning basin channel improvements commenced July 1, 2020 and is anticipated to conclude June 30, 2023. A draft Integrated Feasibility Report (IFR), which includes compliance with the National Environmental Policy Act (NEPA), was released for public review on December 17, 2021. USACE has requested comments related to the IFR be submitted by January 31, 2022. The California Environmental Quality Act (CEQA) draft document is anticipated for public review late 2022. Tentatively, and subject to change, pre-construction engineering and design (PED) is anticipated between 2024-2026 with construction activity occurring between 2027 and 2029.

Benefits: Widened turning basins allow vessels to operate efficiently within the Oakland Harbor. These efficiencies result in decreased a) restrictions, b) in harbor transit times, and c) transit emissions. Additional benefits include those afforded with economies of scale.

Partnership: United States Army Corps of Engineers (USACE) is leading the feasibility study with cost-sharing and environmental support from the Port of Oakland.

Stakeholders: Including, but not limited to: neighboring communities in Alameda and Oakland, Port tenants, Port customers, Port users, Port workers, industry associations, environmental groups, regulatory agencies, and cities of Oakland and Alameda.
