Brewer Island is an island in the San Francisco Bay, in San Mateo County, California. Originally owned by W. P. A. Brewer, for over one hundred years it was used for hay farming. Several attempts to develop the island failed between 1912 and 1959. Ultimately, a venture by Richard Grant and T. Jack Foster succeeded in 1960; Brewer Island's surface was raised by 6 ft (1.8 m), an artificial lake was dug in its center, and it became the location of what is now known as Foster City.
