In spite of the city's name, most residents live in the "flats" of Beverly Hills, which is a relatively flat land that includes all of Beverly Hills itself. The houses situated in the hillside north of Sunset Boulevard have a much higher value than the average home price for the rest of the city. Santa Monica Boulevard divides the "flats" into two areas, locally known as "North or South of the tracks," referring to the train tracks that were once used by the old Pacific Electric streetcar line that traversed Beverly Hills along Santa Monica Blvd.
Houses south of Wilshire Boulevard have more urban square and rectangular lots, in general smaller than those to the north. There are also more apartment buildings south of Wilshire Blvd. than anywhere else in Beverly Hills, and the average house value south of Wilshire is the lowest in Beverly Hills. Other locations commonly associated with Beverly Hills include the Cedars-Sinai Medical Center and the Beverly Center, just outside the city limits to the east.
Understatedly one of the best neighborhoods in Los Angeles, the Beverly Hills Post Office, often abbreviated B.H.P.O. is home to some of the most exclusive guard gated community such as Beverly Park, Mulholland Estates, and The Summit—attracting celebrities and royalty alike. The central location makes navigating Los Angeles easier and offers an array of price points. Outside of these gated communities, the hillside can generally be divided into Benedict Canyon and Coldwater Canyon.
Benedict Canyon is a ravine that drops in a north-to-south direction from its high point at the crest line in the Santa Monica Mountains; to the east of the Canyon are its two sisters, Franklin Canyon and Coldwater Canyon.
