General / Marine Construction (Excluding Bridges) / Facilities, Barriers, Manmade Reefs, Riprap, Jetties / Dikes
Contractors for the U.S. Army Corps of Engineers will conduct marine operations for levee rehabilitation along the Sacramento River between River Miles 47.3 and 53.5 . Waterside work is scheduled to begin July 6, 2026, and will continue through approximately November 30, 2026. Operations will involve up to three crane barges (including Crane Barge #12, measuring approximately 140' x 50'), a tugboat, two workboats, and a rotation of flat deck barges. Work will occur during daylight hours; however, barge maneuvering outside the construction area may occur 24 hours a day. Flat deck barges will transit between the job site and the San Rafael Rock Quarry, utilizing pre-existing moorings along the Sacramento River, including locations at River Miles 26 and 27 near Walnut Grove, CA. At the end of each shift, barges will be spudded in place and marked with steady burning white lights on all corners. Mariners are advised to use extreme caution, transit at their slowest safe speed to minimize wake, and maintain a safe distance. Project vessels will monitor VHF-FM channels 9, 16, and 68A, and can be contacted directly at (707) 333-5029.
