Redwood Shores is an affluent waterfront neighborhood on the San Francisco Peninsula in California. It is located on the eastern edge of Belmont, but is actually part of incorporated Redwood City. Redwood Shores is populated with million dollar homes,waterfront marinas and corporate headquarters of tech companies like Oracle Corporation and Electronic Arts. Annual rowing competitions such as the Pac-10 and Redwood Shores Rowing Classic are held in the Redwood Shores Lagoon and most of the houses and condominiums surround the lagoon with access to water through private boating docks. Redwood Shores was built up from landfill in the marshes of the San Francisco Bay in the 1960s, much like its neighbor on the north side, Foster City. To the south it is bordered by the San Carlos Airport. From the 1960s to 1980s it was the home of the Marine World/Africa U.S.A., California park, but in 1986 the park moved to Vallejo, California (eventually becoming Six Flags Discovery Kingdom), and the land was occupied by the headquarters of Oracle Corporation. Redwood Shores is also the home to the Pacific Athletic Club, a private sports club with tennis,squash, pool, yoga, gym and club house facilities, hotel Sofitel Bay Area, Sandpiper Elementary School and community based Redwood Shores Health Center
