Underground Flow Equalization System

UFES Schedule Update – February 6, 2023

UFES Project Schedule for February 6, 2023 – March 6, 2023

We’re making great construction progress toward pollution prevention in San Mateo. The current 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 already know that construction is underway on our UFES at the County Event Center. Once completed, our UFES will eventually be the underground 5.3-million-gallon structure that will temporarily hold excess wastewater during storms.

The following construction work is planned for the UFES project from Feb. 6, 2023 through Mar. 6, 2023. (Please note, schedules can change. We will issue this update in the first full week of every month throughout 2023):

  • Inside the Event Center Site: Additional concrete pours requiring after-hours approval.
  • S. Delaware Street: Equipment installation and removal related to pipeline work will continue.
  • Saratoga Drive: Lane closures for Saratoga Drive in the vicinity of the San Mateo County Event are in place. Please watch for signs indicating traffic pattern changes.

Alerts will be sent via newsletter and text message ahead of work requiring traffic updates, work hour changes, or expected to generate excess noise at the Event Center site.

Pipeline work along South Delaware Street and Saratoga Drive is expected to be complete in Spring 2023. The City anticipates that the UFES project in its entirety, including work at the San Mateo County Event Center, will conclude by the end of 2023.
