Prework has begun on the Oakland Inner Harbor Pipeline Crossing, which will replace an existing transmission pipeline crossing near the Posey Tube that has reached the end of its useful life. The new pipeline will be installed beneath the Oakland Inner Harbor approximately 1,500 feet to the East of the existing crossing via Horizontal Directional Drilling (HDD). This entails fusing the 3,000-foot-long, 24-inch diameter HDPE pipeline together on the Alameda side, drilling a borehole beneath the harbor floor from Alameda to Oakland, and pulling the new pipeline through the borehole. Additionally, the District’s contractor will be installing nearly two miles of 24-inch steel pipeline in Oakland and Alameda which will connect the new crossing to existing transmission mains and further improve the hydraulic connectivity between Alameda and Oakland.
The HDD work is expected to finish in Spring 2023, and all work on the project is expected to finish in Winter 2023. During construction, the community can expect increased traffic in the vicinity of the work, detours and/or temporary lane closures, and construction-related noise. There are no planned water outages associated with this work. Typical project work hours are from 7 a.m to 5 p.m, Monday through Friday. If extended hours or night work are required, the community will be notified in advance.
A virtual public meeting is scheduled for Wednesday, October 5, at 6pm. You can join the meeting by accessing the Zoom link posted here at noon, on the day. You will have the opportunity to ask questions and get more information at the meeting.
