This project will address improvements at two locations supporting the operation of the lagoon system: 1. Replace the intake gates on the lagoon side of the intake structure near Wheel House Lane; and 2. Provide for above and below grade improvements to the lagoon pump station building at the City's Corporation Yard. Water from the San Francisco Bay flows through the intake structure located near the end of Wheel House Lane into the lagoon. In 2018, as part of CIP 301-629, the three (3) exterior gates on the Belmont Slough side of the lagoon intake structure were replaced. The interior gates were constructed in the early 1960's and are starting to fail along with the concrete wall. These reinforced concrete structures are exposed to the salty water and air of the Bay, which causes the reinforcing steel to corrode. The corroding reinforcing steel causes concrete to spall. The lagoon pump station located at the City/District's Corporation Yard, houses two (2) engines/pumps used to pump lagoon water into the bay to control the water level in the interior lagoon. It was constructed in the early 1960's and is one of the oldest City-owned buildings. Water flows through the culverts under the lagoon pump station building and is pumped into the Bay from the Lagoon Pump Station Building. In several locations, significant amounts of concrete have spalled away which adversely affects the structural integrity of certain elements of the facilities. In addition, numerous structural code changes have been adopted since the design of this building. In a report prepared by Murray Smith, Inc. in May 2021, as part of CIP 301-690-Sesimic Improvements project, recommendations were made to perform an in-depth evaluation of the building to include additional structural evaluation of the lagoon pump station building and the below water structures based on current building code standards. The recommendation included further structural investigation and analysis of the lagoon walkway, channels, trash racks (previously replaced in 2010), and foundation, to determine potential structural deficiencies with the intent to replace. This project will provide for a seismic analysis of the building including recommendations for structural improvements required to meet current standards and/or potential replacement of the building. Based on the analysis, a construction budget will be identified, and any additional funding requests will be brought back to the City Council. In addition, analysis will be conducted of the intake structure at Wheel House Lane, especially noting the structural condition of the concrete. The project is included in the City of Foster City's FY 2024-2028 Capital Improvement Program (CIP). As of May 8, 2024, information regarding a design team or a general contractor is not available. Funding is anticipated from 2024 to 2027.*
*Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
