The Foster City levee system, surrounding the majority of the outer bay-front perimeter of the City, is crucial in providing protection from flood hazards and storms. In 2014, the Federal Emergency Management Agency (FEMA) determined that our levee system does not meet minimum requirements for flood protection.
In order to maintain FEMA accreditation and keep Foster City properties out of the flood zone, Foster City voters approved Measure P in 2018 with nearly 81% support, authorizing the City to issue a $90 million general obligation (GO) bond to improve and strengthen the Foster City levee system. Measure P will cost the property owner approximately $40 per $100,000 of assessed (not market) property value annually for levee improvements for 30 years instead of the estimated $2,000-$3,000 or more per year in flood insurance indefinitely.
The measure provides funds to strengthen the levee to meet FEMA standards, keeping Foster City properties out of the flood zone and allowing residents to avoid mandatory expensive flood insurance. Levee improvements will not only allow Foster City to maintain FEMA accreditation, but also protect essential city services during storms and protect the levee from earthquake damage.
Construction of these significant improvements began in October of 2020, and will continue through 2023. During construction, there will be some unavoidable impacts such as traffic delays, an increase in the level of noise and dust, and interruption of the recreational use of the levee trail.
We appreciate your patience and cooperation as the work is completed! The City will be closely working with the contractor to mitigate these impacts as much as possible and will make every effort to minimize any inconvenience and disruption. Once the work is completed, Foster City’s improved levee (which will be more resistant to earthquake damage) will protect homes, schools, businesses, and essential City services and infrastructure from storms and high tide, for years to come. See the links below for more detailed information about the Foster City Levee Protection Planning and Improvements Project.

What Will the Levee Look Like?
These renderings are intended to be representational and of a general nature only. The final appearance of the levee and structures may differ from these illustrations. The varied coloring shown on the sheet pile walls is intended to be shadowing representing the surface’s corrugations, and is not a color pattern. Click on each image for larger versions.
3. Approximate Location: San Mateo Bridge Undercrossing I Wall Type: Concrete Flood Wall
Note: This represents a short section of the levee wall where the concrete wall will be nearly four feet, as the trail slopes down to existing grade, and is not typical of the majority of concrete flood wall height.
