UFES Construction Update – December 15, 2021

Work along Saratoga Drive

The City’s contractor will continue work along Saratoga Drive, between the main entrance to the San Mateo County Event Center and S. Delaware Street, into the week of Dec. 20, 2021, to remove sheet piles and other equipment. During this work, residents can expect some short-term inconveniences such as loud noise.

Please note: Approved work hours along Saratoga Drive are between 7 a.m. and 5 p.m.

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