Off-hours work related to the UFES project has been approved by the City of San Mateo for Thursday, May 26, 2022.Work will include an additional concrete pour in the excavation at the San Mateo County Event Center site.

While we expect that the main pouring activities will conclude before 7 p.m., finishing activities could extend into the evening.

Nearby residents may experience additional truck traffic on this day before, during, and after the regular approved hours of 7 a.m. through 7 p.m. During this work, residents can expect some short-term inconveniences such as loud noise.

We thank you for your continued patience and cooperation as we make steady progress towards the completion of our sewer system improvements.
