The lands now occupied by the City of San Ramon were formerly inhabited by Seunen people, anOhlone/Costanoan group who built their homes near creeks. Sometime around 1797, they were taken byMission San José for use as grazing land. In 1834, they were part of theRancho San Ramon land grant toJosé María Amador.[11]
The area went through several informal names in the 1800s, including Brevensville, Lynchville, and Limerick.[12] Amador namedSan Ramón (Spanish for 'Saint Raymond') after a Native Americanvaquero 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.[11] In 1873, San Ramon became the official place name when a permanent post office was opened, further established when a railroad arrived.[12]
The tracks for the San Ramon Branch Line of theSouthern Pacific Railroad were laid down and completed in 1891. The line extended from San Ramon to an unincorporated area known as Avon, east ofMartinez, 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 railroadright-of-way and theIron Horse Regional Trail was established along its path.[11]
On April 24, 2001, San Ramon was designated aTree City USA.[13]
Mount Diablo flanks the city to the northeast and is prominently visible from almost all parts of the city. TheLas Trampas Regional Wilderness borders San Ramon's extreme northwest, at the northern end of Bollinger Canyon. The smallerBishop Ranch Regional Preserve straddles San Ramon's western border, located approximately betweenInterstate 680 and theAlameda County line.
The topography of San Ramon is varied, featuring a mix of the rolling hills of theDiablo Range and the flatter basin of theSan 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 bygrasslands andoak 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 aMediterranean climate, seasonal, and moderate. Summers can range from warm to hot and dry, while winters are mild or cool, wet and rather short.[14] Its weather is similar to the adjacent cities ofDanville,Dublin andPleasanton.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 theSan Francisco Bay viaCastro Valley. It usually burns off by mid-to-late morning.
