San Ramon, California

San Ramon (Spanish: San Ramón, meaning "Saint Raymond") is a city in Contra Costa County, California, United States, located within the San Ramon Valley, and 34 miles (55 km) east of San Francisco. San Ramon's population was 84,605 per the 2020 census, making it the 4th largest city in Contra Costa County, behind Concord, Richmond and Antioch.
San Ramon is home to the headquarters of Chevron Corporation, Cooper Companies, the West Coast headquarters of AT&T, GE Digital, as well as the San Ramon Medical Center. Major annual events include the Art and Wind Festival on Memorial Day weekend and the Run for Education in October.
The lands now occupied by the City of San Ramon were formerly inhabited by Seunen people, an Ohlone/Costanoan group who built their homes near creeks. Sometime around 1797, they were taken by Mission San José for use as grazing land. In 1834, they were part of the Rancho San Ramon land grant to José María Amador.
Amador named San Ramón (Spanish for 'Saint Raymond') after a Native American vaquero who tended mission sheep on the land. Amador added the "San" per Spanish custom. In 1850, the first permanent American settlers, Leo and Mary Jane Norris, purchased the northwest corner of Amador's Rancho San Ramon, near the intersection of present-day Bollinger Canyon Road and Crow Canyon Road.
The tracks for the San Ramon Branch Line of the Southern Pacific Railroad were laid down and completed in 1891. The line extended from San Ramon to an unincorporated area known as Avon, east of Martinez, where it connected to the Oakland/Stockton Line. On February 7, 1909, Southern Pacific extended the line south to Radum (near Pleasanton). In 1934, passenger service ended. By 1986, Contra Costa County had obtained the railroad right-of-way and the Iron Horse Regional Trail was established along its path.
On April 24, 2001, San Ramon was designated a Tree City USA.
Mount Diablo flanks the city to the northeast and is prominently visible from almost all parts of the city. The Las Trampas Regional Wilderness borders San Ramon's extreme northwest, at the northern end of Bollinger Canyon. The smaller Bishop Ranch Regional Preserve straddles San Ramon's western border, located approximately between Interstate 680 and the Alameda County line.
The topography of San Ramon is varied, featuring a mix of the rolling hills of the Diablo Range and the flatter basin of the San Ramon Valley. The city is predominantly urban and residential with many new housing developments; however, much of the land around the city's perimeter regions remains undeveloped, and is covered by grasslands and oak tree orchards. During the drier months the grasses are golden, but with the precipitation of winter and spring, the grasses turn green.
San Ramon's weather typifies a Mediterranean climate, seasonal, and moderate. Summers can range from warm to hot and dry, while winters are mild or cool, wet and rather short. Its weather is similar to the adjacent cities of Danville, Dublin and Pleasanton. Fog can be infrequent but occurs normally in the western reaches of the city, at the eastern mouth of Crow Canyon, through which marine weather patterns funnel in from the San Francisco Bay via Castro Valley. It usually burns off by mid-to-late morning.

Bishop Ranch, a master-planned office park development, with some retail elements, began major construction in the early 1980s, and provides a healthy tax base for the city. Bishop Ranch is situated on 585 acres once owned by Western Electric, and was farmland before that. Current tenants include the corporate headquarters of Chevron Corporation (formerly ChevronTexaco), as well the West Coast headquarters of AT&T Inc. (which had been the headquarters of Pacific Bell from about 1983, when it relocated from downtown San Francisco, until the merger with SBC Communications that created the current AT&T). United Parcel Service has a regional distribution center in Bishop Ranch. Toyota has a regional office and parts distribution center located there. GE Global Research started its Global Software Center in Bishop Ranch in 2011. Bishop Ranch covers the vast majority of "Central San Ramon", which is the large square formed by Freeway 680 on the west, Crow Canyon Road on the north, Iron Horse trail on the east, and Bollinger Canyon Road on the south (though several complexes are south of Bollinger). In December 2016, the Ligier EZ-10 began use in the first autonomous vehicle passenger shuttle route in North America, looping through Bishop Ranch Office Park, with on-sight operation and maintenance by First Transit.
ChevronTexaco's headquarters moved from San Francisco to San Ramon in 2001 but 12 years later, 800 jobs were moved to Houston, a quarter of the San Ramon workforce due to high corporate costs and to consolidate existing units in Houston.

San Ramon features 58 separate parks and an 18-hole golf course, the San Ramon Golf Club.
Originally, this city park, located on a hill overlooking Bollinger Canyon Road and San Ramon Valley Blvd., was to be named Alta Mesa Park. During the construction of the park, the City Council voted to change the name to Memorial Park to honor Tom Burnett, a San Ramon resident, and other victims from Flight 93 killed in the September 11 attacks of 2001. A plaque was installed at the base of a lighted flagpole dedicated to those victims and the surrounding meadow is part of the city's memorial tree program dedicated to local residents who have perished. The park was dedicated on September 11, 2002.
This 16-acre park includes a play area, a BMX course, a picnic area, a bocce ball court, horseshoe courts, a ball field, a dog park, restrooms and water fountains (including a doggy water fountain). The play area has two big play structures, one for ages 2–5 and another for ages 5–12.
