Foster City's lagoon system and miles of waterways covering a surface area of more than 200 acres, provide numerous recreational opportunities. Powerboats are prohibited at all times on the lagoon. Sailing on the beautiful blue lagoon that winds five miles throughout the City is one of the most popular leisure sport activities.
