Hillsborough is an incorporated town in San Mateo County, California, in the San Francisco Bay Area. Hillsborough is one of the wealthiest places in America and has the highest income of places in America with populations of at least 10,000. It is located seventeen miles (27 km) south of San Francisco on the San Francisco Peninsula, between Interstate 280 and SR 82 (El Camino Real). The population was 10,825 at the 2000 census. The town is served by Hillsborough City School District. Hillsborough is home to some of the Bay Area's wealthiest people, and the landscape is dominated by large homes; the city enforces a 2,500-square-foot (230 m2) minimum house size and half-acre minimum lot size to preserve exclusivity.[1] As a result, there are no apartments, condominiums or townhouses in the city limits; however, it is not unusual for the homes along the eastern edge of Hillsborough to face condominiums in neighboring Burlingame, with which it shares ZIP code 94010. In 2007, Coldwell Banker lists Hillsborough as the most expensive housing market in the United States, with a median home price of over $3.8 million.



Hillsborough is located on the Rancho San Mateo Mexican land grant which was purchased by William Davis Merry Howard, son of a wealthy Hillsboro, New Hampshire shipping magnate, in 1846. Howard settled his family in this area, which attracted wealthy San Franciscans. In 1910, Hillsborough residents voted to incorporate.[2]

Geography and environment

Hillsborough is located at 37°33′37″N 122°21′23″W / 37.560199°N 122.356277°W / 37.560199; -122.356277.[3]

According to the United States Census Bureau, the town has a total area of 6.2 square miles (16.1 km²), all of it land. The area's hilly topography and lack of use of a grid layout for roads make navigation by outsiders notoriously difficult. The area of Crystal Springs Road is one of the most difficult to navigate.

There are two prominent streams that drain the mostly wooded slopes of Hillsborough: San Mateo Creek and Cherry Creek. In both cases the upper watersheds are closed canopy California oak woodlands, with dominant trees of Coast Live Oak, Pacific Madrone and California Bay.

The upper drainage area of San Mateo Creek in Hillsborough contains significant serpentinite outcrops, which are known habitats for several rare plant species including the San Mateo Woolly Sunflower.[4] Other common plants include Toyon, gooseberry, lupine, monkeyflower and coffeeberry. Commonly observed mammals include California Mule Deer, raccoon, opossum and skunk.

Hillsborough is bordered to the west by Interstate 280, and to the south by Crystal Springs Road which runs along San Mateo Creek. The San Mateo Highlands borders Hillsborough to the south across San Mateo Creek.
