Los Altos is a city in Santa Clara County, California, in the San Francisco Bay Area. Most of the city’s growth occurred between 1950 and 1980. Originally an agricultural town with many summer cottages and apricot orchards, Los Altos is now an affluent bedroom community on the western edge of Silicon Valley, serving as a major source of commuters to other parts of Silicon Valley. Los Altos strictly limits commercial zones to the downtown area and small shopping and office parks lining Foothill Expressway and El Camino Real.
Adobe Creek flows through Redwood Grove, a 5.9-acre nature preserve off University Avenue in Los Altos purchased by the city in 1974. In October 2009 Los Altos contracted with Acterra to remove non-native plants and revitalize the redwood, oak woodland, riparian and grassland ecosystems by installing native plants, improving soil conditions, and creating habitat for wildlife such as bird houses and native bee boxes.
