Pacific Heights is an affluent neighborhood of San Francisco, California, which is known for the notable people who reside in the area. It is located in one of the most scenic and park-like settings in northern California, offering panoramic views of the Golden Gate Bridge, San Francisco Bay, the Palace of Fine Arts, Alcatraz, and the Presidio. Its location provides a temperate micro-climate that is clearer, but not always warmer, than many other areas in San Francisco. The Pacific Heights Residents Association defines the neighborhood as inside Pine Street, Presidio Avenue, Union Street, and Van Ness Avenue. In 2013, Pacific Heights was named most expensive neighborhood in United States stating that if San Francisco's Pacific Heights had its own zip code, it would be the most expensive place to live in the United States. The 94115 zip code includes both Pacific Heights' "Gold Coast," an area famous for its billionaire residents and record-breaking prices, and "The Western Addition," an area about 20 blocks away where real estate prices are significantly lower. Pacific Heights is situated on a primarily east-west oriented ridge that rises sharply from the Marina District and Cow Hollow neighborhoods to the north to a maximum height of 370 feet (110 m) above sea level. Pacific Heights features two parks, Lafayette and Alta Plaza. Visible to the north are the Golden Gate Bridge, the Marin Headlands, and Alcatraz Island. Lower Pacific Heights refers to the area located south of California Street down to Post Street. Though previously simply considered part of the Western Addition, this new neighborhood designation became popularized by real estate agents in the early 1990s. - source: Wikipedia
