UFES Work Hour Update – February 25, 2021

After-Hours Work Approved for March 1, 2021

After-hours work related to the UFES project has been approved by the City of San Mateo for Mar. 1, 2021. Work will include transporting support steel needed for UFES pipeline work across the San Mateo County Event Center parking lot and along Saratoga Dr. This work has been scheduled during the evening to lessen the impact on daytime traffic. Nearby residents may experience some intermittent noise from handling steel, but the contractor will proactively work to minimize the noise. No dust or vibration impacts are expected from this work. Traffic flaggers and pilot cars will be used as needed, and signs will be posted if this work results in additional traffic pattern changes.
