Is Foster City in a flood zone, and is flood insurance mandatory now?

No, the Federal Emergency Management Agency (FEMA) has temporarily placed the City in a ‘seclusion zone’ status while the City makes progress to increase the height of the levee.

Flood insurance is not presently required in Foster City. However, if the height of the levee is not increased, FEMA accreditation of the levee will be lost, and the City would be placed in a flood hazard zone when FEMA’s next Flood Insurance Rate Map (FIRM) is released. At that time, flood insurance would be required for property owners with federally backed loans.
