Flood Control and levee improvements project

In order to maintain FEMA accreditation and keep Foster City properties out of the flood zone, the City is constructing 6.5 miles of sea walls, upgrading the existing levee structure, and increasing the height of the levee. The project includes 22,100 LF of Sheet Pile Floodwall, 5,100 LF of Earthen Levee and 4,100 LF of Convention Floodwall. In certain sections where land area is constrained, a secondary retaining wall will be constructed on the landside of the trail to transition the elevated levee grade down to the existing grade.

In addition to raising the levee, the project includes the redevelopment and widening of the existing Bay Trail and construction of two bridges to increase tidal circulation to enhance the O’Neill Slough in the southern segment of the project site. The project consists of extensive public outreach and permit compliance from four major agencies: State Lands Commission (SLC), the Regional Water Quality Control Board (RWQCB), the San Francisco Bay Conservation and Development Commission (BCDC), and the U.S. Army Corps of Engineers (USACE).
