Underground Flow Equalization System

UFES Schedule Update – April 1, 2024

UFES Project Schedule for April 1, 2024 – May 6, 2024

We’re making great construction progress toward pollution prevention in San Mateo. The recent rainy season reminds all of us why our 10-year, $1 billion Clean Water Program is so essential to the future of our City.

One of the most important projects in the program is our Underground Flow Equalization System (UFES).

As a follower to this newsletter, you know that construction of our 53-million-gallon UFES at the County Event Center is nearing completion. Once completed, it will temporarily hold excess wastewater during storms.

The following construction work is planned for the UFES project from April 1, 2024 through May 6, 2024. (Please note, schedules can change. We will issue this update in the first full week of every month through Spring 2024.):

  • Inside the Event Center Site: Contractor has begun paving.
  • S. Delaware Street: Major traffic pattern changes are complete; however, occasional minor traffic inconveniences may continue until the project is complete.
  • Saratoga Drive: There will be some continued traffic impacts related to landscape restoration.
  • Bay Meadows Park: construction of the retaining wall near Bay Meadows Park is complete. Contractors are preparing to install a fence separating the UFES site from the entrance driveway.

Although not anticipated, alerts will be sent via newsletter and text message ahead of any remaining work requiring significant traffic updates or work hour changes at the County Event Center site.

The City anticipates that the UFES project in its entirety, including work at the County Event Center site, will conclude in early Summer 2024. Once the project is complete, it will be able to reduce the sanitary sewer overflows that result from excessive rainfall, which the community may have witnessed during the recent storms.

For questions or concerns, please contact the UFES hotline at 1-650-522-7250 or email us at info@CleanWaterProgramSanMateo.org.

We thank you for your continued patience and cooperation. Visit our UFES page for complete project details.
