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 km) east of the city of Oakland. With a total estimated population of 69,122, Walnut Creek serves as a 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, restaurants and entertainment venues.

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) near Mt. Diablo; and the Tactan located on the San Ramon Creek in Danville and Walnut Creek.
Today's Walnut Creek is located within 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 eventually passed the land down 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 las Nueces was named for the evidence of the native species of walnut tree, the California Walnut.
With the coming of American settlers following the Mexican–American War, a small settlement called "The Corners" emerged, named because it was the place where roads from Pacheco and Lafayette met. The site of this first American settlement is found today at the intersection of Mt. Diablo Boulevard and North Main Street. The first town settler was William Slusher, who built a dwelling on the bank of Walnut Creek, which was called "Nuts Creek" by the Americans in 1849. In the year 1855, Milo Hough of Lafayette built the hotel named "Walnut Creek House" in the corners. A blacksmith shop and a store soon joined the hotel, and a year later, Hiram Penniman (who built Shadelands Ranch) laid out the town site and realigned the Main Street of today. Two decades later, the community changed its name from The Corners to Walnut Creek.
In December 1862 a United States Post Office was established, and the community was named "Walnut Creek". The downtown street patterns laid out in 1871–1872 by pioneer Homer Shuey on a portion of one of his family's large cattle ranches are still present today.
Walnut Creek began to grow with the arrival of Southern Pacific Railroad service in 1891. On October 21, 1914, the town and the surrounding area of 500 acres (2.0 square kilometres)), were incorporated as the 8th city in Contra Costa County. A branch line of the Southern Pacific railroad ran through Walnut Creek until the late 1970s. The East Bay Regional Park District's Iron Horse Trail, used by walkers, runners and bikers, runs over what were portions of that branch line. The mainline of the Sacramento Northern Railway passed through Walnut Creek. Both railroads had stations here. Today, the Antioch–SFO/Millbrae line of the Bay Area Rapid Transit (BART) serves Walnut Creek with a station adjacent to Highway 680.
With the 1951 opening of the downtown Broadway Shopping Center (now Broadway Plaza), Contra Costa County's first major retail center, the city took off in a new direction, and its population more than quadrupled – from 2,460 in 1950 to 9,903 in 1960.
Geography and climate
Walnut Creek is located at  Portions lie in both the San Ramon Valley and the Ygnacio Valley below the western slopes of Mount Diablo. According to the United States Census Bureau, the city has a total area of 19.8 sq mi (51.2 km2), 0.06 percent of which is water. Walnut Creek – the actual waterway that runs through town – has been routed underneath downtown through a series of tunnels starting at the southwest end of Macy's and ending just southwest of Maria Maria Restaurant..
Walnut Creek owns more open space per capita than any other community in the state of California. In 1974, Walnut Creek voters approved a $6.7 million bond measure that allowed the city to purchase 1,800 acres (730 ha) of undeveloped hillsides, ridge lines, and park sites. Walnut Creek owns parts of Lime Ridge Open Space, Shell Ridge Open Space, Acalanes Ridge Open Space, and Sugarloaf Open Space.
Walnut Creek's warm summer Mediterranean climate (Köppen climate classification Csb) is typical of California's interior valleys. In summer, high pressure is in control of the region, leading to almost unbroken sunshine and virtually no precipitation. Days start out cool but quickly warm up, with high temperatures normally in the 80s Fahrenheit (27 to 32 °C). Temperatures of 100 °F (38 °C) or hotter occur numerous times during heatwaves, however. In the winter, the jet stream moves far enough south so that Pacific storms can reach Walnut Creek, bringing much-needed rain – average annual rainfall approximates 20 inches (510 mm), with slight variations occurring in microclimates based on elevation and topography. During particularly cold storms, snow falls on the peak of nearby Mount Diablo, but snow in the valley floor is very rare. There are also plenty of clear, mild days in winter, often with morning frost. The climate allows for the successful cultivation of many plants and crops, being warm enough for citrus yet cold enough for apples. The Ruth Bancroft Garden is a renowned botanical garden that showcases the diversity of plants that can be successfully grown.

Public transit and bike trails
The city hosts two BART stations, Walnut Creek station and Pleasant Hill station (in the unincorporated area known as Contra Costa Centre Transit Village). BART provides direct service from Walnut Creek to San Francisco, heading west, and Antioch, heading east. Other cities such as Berkeley and Fremont can be accessed via transfers.
Central Contra Costa Transit Authority (County Connection/CCCTA) provides bus service throughout Walnut Creek and Contra Costa County at a modest cost. County Connection also operates three free weekday shuttles within city limits: the Downtown Trolley/Route 4 loops from Walnut Creek BART to Broadway Plaza; Route 5 runs from Walnut Creek BART to Creekside; and Route 7, which runs from Pleasant Hill BART to Shadelands Business Park.
Walnut Creek is transected by the Iron Horse Trail (running north/south) through its downtown, as well as the Contra Costa Canal Trail (running east/west) at the north end of the city. Both these trails, in addition to city bike lanes, make bicycle transportation feasible for both recreation and an alternative commute.
