Alta Plaza consists of four square blocks at the top of Pacific Heights and overlooks much of San Francisco's Marina and Cow Hollow Districts, the Presidio, Fort Mason and Alcatraz. It is bordered by Jackson Street on the north, Clay Street to the south, and with Steiner and Scott Streets on its east and west edges, respectively. The plaza cuts off the east–west continuation of Washington Street and north–south continuation of Pierce Street. The plaza provides three hard surface tennis courts and a small playground in its center and has a large grass park on its northern half and terraced lawns on it southern half.[3]
