North Shoreview Flood Improvements Project

The North Shoreview Flood Improvements Project, solicitation number 468202, is a public works initiative by the City of San Mateo, California, focused on critical infrastructure upgrades to enhance flood protection. The scope of work primarily involves the replacement of the Coyote Point and Poplar Avenue pump stations, improvements to the Coyote Point levee, and the installation of a pre-engineered inline hydrodynamic separation system. Key technical components include the construction of diversion weirs, trash capture devices, stop log guides, and the placement of compacted levee fill and rock slope protection. The project is supported by extensive geotechnical investigations addressing subsurface conditions, seismic hazards, and soil stability to ensure the integrity of the levee and pump station foundations. The project follows a construction timeline starting with an anticipated Notice to Proceed in Summer 2020, with a performance period of 650 working days to reach substantial completion, followed by a one-year plant maintenance period. Contractual requirements are governed by the Greenbook Standard Specifications for Public Works Construction and specific project addenda that revised bid items to include landfill disposal and PG&E delay contingencies. Bidders were required to submit proposal forms and a revised schedule of bid items by March 5, 2020. Quality assurance is managed through rigorous inspection and acceptance criteria, including ASTM standards for soil compaction and pipe integrity, with final acceptance contingent upon the Engineer's approval at the project site.
