Walnut Creek, CA
Walnut Creek is an incorporated city located 16 miles (26 km) east of the city of Oakland. It lies in the East Bay region of the San Francisco Bay Area. While not as large as neighboring Concord, Walnut Creek serves as the business and entertainment hub for the neighboring cities within central Contra Costa County, due in part to its location at the junction of the highways from Sacramento and San Jose (I-680) and San Francisco/Oakland (SR-24), as well as its accessibility by BART. The city had a total population of 64,173 according to the 2010 U.S. Census. Walnut Creek is the headquarters of the Pac-12 Conference.
There are three bands of Bay Miwok Indians associated with early Walnut Creek: the Saclan, whose territory extended through the hills east of present day Oakland, Rossmoor, Lafayette, Moraga, and Walnut Creek; the Volvon (also spelled Bolbon, Wolwon, and Zuicun) at Mt. Diablo; and the Tactan at Danville and Walnut Creek, on San Ramon Creek.
Today's Walnut Creek is located amidst the earlier site of four Mexican land grants. One of these land grants – measuring 18,000 acres (73 km2) – belonged to Juana Sanchez de Pacheco, who deeded it to her two grandsons. Ygnacio Sibrian, one of the grandsons, created the first roofed home in the valley in about 1850. The grant was called Rancho Arroyo de Las Nueces y Bolbones, named after the principal waterway, Arroyo de las Nueces (Walnut Creek) as well as for the local group of indigenous Americans (Bolbones). The Arroyo de los Nueces was named for the occurrence in the valley of the native species of walnut tree, the California Walnut.
