The Dutra Group will conduct marine operations for levee breach closure and rehabilitation along Suisun Slough adjacent to Joice Island near Suisun City, California, at approximately 38-11.48N 122-02.12W. Waterside work will begin on or about October 5, 2026, and continue through no later than November 30, 2026. Operations will include the Crane Barge TM20, work boat, tugboat, and rotating flat deck barges. The crane barge will be spudded at various locations within the construction area. Flat deck barges will transit between the project site and the San Rafael Rock Quarry and may be moored at pre-existing moorings along Suisun Slough during mobilization. Work will occur during daylight hours; however, barge movements outside the construction area may continue at all hours. At the end of each shift, barges will be spudded in and display steady-burning white lights on all corners. Vessels will monitor VHF-FM channels 9 and 16, with Channel 68A as the working channel, and may be contacted at (707) 333-5029. Mariners are advised to use extreme caution while transiting the construction site and are urged to transit at their slowest safe speed to minimize wake. All mariners are advised to transit the area with caution.
