Three Upcoming Public Meetings about the Wastewater Treatment Plant Project

On June 6, Clean Water Program staff will be presenting to the Park and Recreation Commission about the proposed use of three parcels managed by the San Mateo Parks and Recreation Department. These parcels would be used for offsite construction staging and parking areas to support upcoming construction activities related to the upgrade and expansion of the City’s wastewater treatment plant. The three parcels proposed for use are the Dale Avenue undeveloped open space, the Anchor Road passive open space, and a portion of the Anchor Road parking lot. The public will be able to comment at this meeting.

On June 12, the Planning Commission meeting will include a public hearing about the application for a Special Use Permit for the project. The Commission will then vote on its recommendation to the City Council. The project includes changes to the existing wastewater treatment plant, and construction of new facilities next to the existing site. Some of the older facilities at the plant will be removed or re-purposed. The project includes a pedestrian path around the plant from Dale Avenue to John Lee Dog Park, modifications to the existing landscaping along East 3rd Avenue, and closure of a portion of Detroit Drive.

On July 16, the City Council meeting will include a public hearing on the Special Use Permit discussed earlier at the June 12 Planning Commission meeting. The City Council will vote on the approval of the Special Use Permit at this meeting.

Water Board Renews City’s Permit and Provides Support for the Clean Water Program’s Approach

In early May, the San Francisco Bay Regional Water Quality Control Board (RWQCB) approved renewal of the operating permit for San Mateo’s wastewater treatment plant under the National Pollutant Discharge Elimination System (NPDES). The NPDES is a program under the U.S. Environmental Protection Agency to prevent water pollution. This permit allows the City to discharge treated wastewater into San Francisco Bay.

San Mateo also received overwhelming support from the RWQCB for its Clean Water Program and the wastewater treatment plant improvement project. Three Board members, including the chair, directly acknowledged San Mateo’s early implementation strategy in preparation for future trends in nutrient removal regulations, the Clean Water Program’s innovative approach using state-of-the art technology, and leadership in promoting these water quality improvement strategies. The RWQCB gave its support to San Mateo, and stated it wants to support other agencies who take these types of actions by encouraging and supporting funding for these types of forward-looking projects.

Glendora/Shasta Sewer Relief Work Begins

As part of the Clean Water Program, approximately 2,000 feet of existing sewer pipes along Shasta and Glendora drives will be replaced and upgraded. This project will replace portions of the sewer pipes in City easements in Shasta Drive residents' backyards or side yards with a new, larger pipe in the street.  Improvements on Glendora Drive will occur in the street.

Most of the construction work will take place in the public right-of-way, but the construction contractor will need to access the pipes in easements on affected properties as part of this work. Any disturbances to surface features and landscaping on private parcels will be replaced in kind. In addition, the contractor performing the work will ensure that safety hazards and odors will be mitigated during the work. After work is completed, Shasta Drive will be repaved.

Construction is currently planned to occur from May 2018 to October 2018. Affected residences will be notified prior to the work for coordination of easement access.

This work is crucial for improving the City’s overall infrastructure, and for preventing sewer overflows that occur during heavy rains. The Clean Water Program and the City of San Mateo want to thank all residents for their continued cooperation!

Closed-Circuit TV Inspections and Sewer Line Cleaning Begin Soon

As part of the Clean Water Program and the Department of Public Works’ routine maintenance of the sewer system, inspection crews will be conducting sewer condition assessments in several neighborhoods. Presidio Systems, Inc. has been hired by the City to clean and inspect sewer mains. Some of these locations include utility easements on private property.

This work helps the City understand how to address aging sewer infrastructure, capacity issues, and sanitary sewer overflows. Inspections will confirm any needed sewer pipe spot repairs, pipe segment replacements, and rehabilitation at various locations throughout San Mateo.

Work locations are shown in blue on the maps below. Affected properties will receive advance notice about the work, and work will be conducted between 8 a.m. and 5 p.m., Monday through Friday.

  • Replacing pumps, valves, and piping;
