UFES Project Update – April 2, 2021

Phase 3 and Pipeline Work for the Clean Water Program’s UFES Project Continue

Since starting in February 2021, Phase 3 construction of the UFES project at the San Mateo County Event Center site has progressed significantly. During this phase, soil from inside the shoring system is being removed, and any water occurring inside the excavation is removed as it is encountered. The ongoing work includes additional equipment, heavier construction, and increased truck traffic for hauling soil from the San Mateo County Event Center to and from Delaware Street. This phase of construction is expected to be complete this summer. Approved work hours at the Event Center site are between 7 a.m. and 7 p.m., Monday through Friday.

Preparations for pipeline work along Saratoga Drive also started in February. Pipe installation will begin this month. While we continually strive to minimize the impacts of our work on our neighbors, you may hear some noise and feel minor vibrations if you are close to where the work is occurring. Approved work hours for work along Saratoga Drive are between 8 a.m. and 4 p.m., Monday through Friday.

Traffic control measures remain in place. The single eastbound lane of Saratoga Drive is being utilized for Event Center traffic only. The single westbound lane of Saratoga Drive allows for through traffic to Delaware Street. Signs are placed in specific areas to provide direction and ensure the safety of drivers.

*Construction schedules and traffic patterns are subject to change.
