Context: Walnut Creek is a city in Contra Costa County, California, United States, located in the East Bay region of the San Francisco Bay Area, about 16 miles (26 kilometers) east of the city of Oakland. With a total population of 70,127 per the 2020 census, Walnut Creek serves as a vibrant hub for its neighboring cities because of its location at the junction of the highways from Sacramento and San Jose (I-680) and San Francisco/Oakland (SR-24), and its accessibility by BART. Its active downtown neighborhood features hundred-year-old buildings and extensive high-end retail establishments. The city shares its borders with Clayton, Lafayette, Alamo, Pleasant Hill, and Concord.
Downtown Walnut CreekThere are three bands of Bay Miwok Native Americans associated with the area of Walnut Creek (the stream for which the city is named): the Saclan, whose territory extended through the hills east of present-day cities of Oakland, Rossmoor, Lafayette, Moraga and Walnut Creek; the Volvon (also spelled Bolbon, Wolwon or Zuicun), who were near Mt. Diablo; and the Tactan, located on the San Ramon Creek in present-day Danville and Walnut Creek.The city of Walnut Creek has developed within the earlier area of four extensive Mexican land grants. One of these land grants – measuring 18,000 acres (73 km2) – belonged to Juana Sanchez de Pacheco. The grant was called Rancho Arroyo de Las Nueces y Bolbones, named after the principal waterway, Arroyo de las Nueces (Walnut Creek in English), and for the local group of Volvon indigenous Americans (also known as Bolbones in Spanish). The Arroyo de las Nueces was named for the local species of walnut tree, the California Walnut. The two grandsons of Sanchez de Pacheco inherited the thousands of acres of land. One, Ygnacio Sibrian, built the first roofed home in the valley in about 1850.
