As part of our commitment to residents in Fiesta Gardens and Bay Meadows in conjunction with the construction of the Underground Flow Equalization System project, the City of San Mateo will be conducting condition assessments at selected properties within a 500-foot radius of the project site. These assessments will be conducted before, during, and after construction and will help the City and its contractor monitor any physical impacts of construction on nearby properties. Right-of Entry packets with detailed information were mailed out to selected properties in early February.
In order to perform these assessments, the City requires written authorization from the property owner or occupant. If you would like your property to be included in these voluntary condition assessments, your signed right-of-entry form is requested by March 31, 2020.
City staff will follow up with you in late Spring 2020 to schedule your initial property condition assessment before the start of construction.
City staff are monitoring the current shelter-in-place order and social distancing recommendations. Because essential Public Works projects are authorized to continue at this time, you may be contacted while still under a shelter-in-place order and/or social distancing recommendations continue; however, our contractors will not conduct the actual assessments until we are assured that it is safe to do so. Our crews will be instructed to follow procedures that will ensure your safety while conducting the assessments.

UFES Construction begins Summer 2020
In late 2019, the City of San Mateo prequalified a select number of contractors for construction of the Underground Flow Equalization System project (UFES) Project. This project is a major component of the City’s Clean Water Program, which is a series of improvements to the sewer system and wastewater treatment plant.
Contractors were prequalified based on their potential ability to meet construction requirements outlined in the Final Environmental Impact Report, which was approved by the San Mateo City Council in October 2019. The City expects to award the construction contract in spring 2020.
Construction is expected to begin in mid-summer 2020, and the project will be completed in six phases over approximately two years: Site preparation (Phase 1) will include installation of construction fencing and dust control, and equipment will arrive on site. The shoring system (Phase 2) will safely hold the area open during excavation, and groundwater will be removed from inside the shoring system to maintain stability. Once shoring is complete, excavation will begin (Phase 3), and the soil inside the shoring will be removed. During Phase 4, foundation piles will be drilled to support the structure and keep it in place. The concrete base, walls, column, beams, and roof will be built during Phase 5. Once the concrete work is done, site finishing (Phase 6) will begin. A new electrical building will be installed, new landscaping features will be added, and the site will be repaved. The new facility will undergo startup and testing before being brought online.
A diversion system will be built near Saratoga Avenue and Delaware Street. This system will divert excess flows away from the main sewer line and to the UFES structure, preventing overflows.
The Clean Water Program thanks everyone for input received throughout the planning process, and looks forward to completion of these upgrades that will benefit the health of our residents, nearby ecosystems, and the San Francisco Bay.
