Oakland Harbor Turning Basins Widening, CA

The U.S. Army Corps of Engineers San Francisco District (USACE), in collaboration with The Port of Oakland (the Port) as our non-federal sponsor, has prepared a second Draft Integrated Feasibility Report and National Environmental Policy Act  Environmental Assessment  as well as a draft Finding of No Significant Impact for the Oakland Harbor Turning Basins Widening Navigation Study in Oakland, Calif.

The second draft IFR/EA is a re-release of the original draft report issued for public review on December 17, 2021; the public comment review period for the original draft closed February 14, 2022. In response to public comment on the initial Draft IFR/EA and operational needs, refinements to the Recommended Plan included slight shifts of the proposed widened footprints of both the inner and outer harbor turning basins. The shift of the proposed widened inner harbor turning basin necessitated an addition to the design for an in-water retaining feature adjacent to the Schnitzer Steel property, which would require in-water fill and in-water pile driving not previously evaluated in the original draft report and IFR/EA.  Moreover, these design refinements identified the need for additional in-water fill in front of the Inner Harbor Turning basin bulkheads after widening. This in-water fill in Waters of the United States requires preparation of a Clean Water Act 404(b)(1) analysis, which had not been necessary nor included in the original IFR/EA. These additional features are described and evaluated in this rerelease Draft IFR/EA and a 404(b)(1) analysis is now included as appendix A-3. A complete list of updates from the initial Draft IFR/EA is located in this re-release executive summary.

The Draft report was re-released April 26, 2023. The comment period closed June 16, 2023.

Written comments were emailed to OaklandHarborTurningBasinsStudy@usace.army.mil or mailed to: Mr. Eric Jolliffe, 450 Golden Gate Ave, 4th Floor, San Francisco, CA 94102.

The U.S. Army Corps of Engineers, in partnership with the Port of Oakland, are conducting a feasibility study to investigate and determine if there is a technically feasible, economically justifiable, and environmentally acceptable recommendation for federal participation in a navigation improvement project to the existing federal navigation channels of Oakland Harbor.

The existing federal navigation channels of Oakland Harbor were designed for a 6,500 twenty-foot equivalent units (TEU) capacity ship with a 1,139 length overall, 140 foot beam, and 48 foot draft as part of the Oakland Harbor Navigation Improvement (-50-Foot) Project Study.  The vessels routinely calling on the harbor today are longer, wider, and deeper than the design vessel from that study.  These inefficiencies have a significant adverse effect on the economics and engineering design of the existing channels.

Initial investigations concluded the problems in Oakland Harbor are caused by length limitations in the inner and outer turning basins and are not caused by depth limitations nor by landside capacity.  The need for this investigation arises from inefficiencies currently experienced by vessels in harbor, specifically the turning basins, where the current fleet exceeds the maximum dimensions of the constructed 50-foot Oakland Harbor Navigation Project.  These inefficiencies are projected to continue in the future as vessel sizes are expected to increase.
