Marina Lagoon Spot Dredging Project

The City of San Mateo is seeking bids for the Marina Lagoon Spot Dredging Project. The project involves dredging accumulated sediment from the Marina Lagoon to remove sediment buildup at the inlets of two freshwater streams that flow into Leslie and Borel creeks. The dredging is authorized under various permits, including a U.S. Army Corps of Engineers permit. The city intends to temporarily store dredged material on site with subsequent transport to a permitted landfill. The bid notice, contract book, plans, and proposal forms can be found in the "Related Documents" section. It is the bidder's responsibility to check back on the website for any addendums that may have been issued. Key aspects of the project include: • Dredging of the inlets of two freshwater streams to a depth no greater than -3 ft NAVD88 + 1 ft over-dredge • Temporary storage of dredged material on site with subsequent transport to a permitted landfill • No decant water during dredging or temporary on-site storage • Sampling and testing performed according to the Inland Testing Manual (ITM) and Dredged Material Management Office (DMMO) guidance
