Alamo (Spanish: Álamo; meaning "Poplar tree") is an unincorporated community and census-designated place (CDP) in Contra Costa County, California, in the United States. It is a suburb located in the San Francisco Bay Area's East Bay region, approximately 28 miles (45 km) east of San Francisco. Alamo is equidistant from the city of Walnut Creek and the incorporated town of Danville. As of the 2020 census, the population was 15,314.
Police services are provided by the Contra Costa County Office of the Sheriff. Fire and EMS services are provided by the San Ramon Valley Fire Protection District.
Alamo has a median household income of $300,000 (as of 2022 [update] ). In August 2007, a group of citizens launched a new initiative to incorporate the community, the latest in a series of attempts that go back to the early 1960s or before; it was defeated by referendum in March 2009. Previous failed Alamo incorporation efforts always included parts of other nearby unincorporated areas: Alamo-Danville (1964) and Alamo-Danville-San Ramon (1976).
Alamo was first inhabited by the Tatcan Indians over 5000 years ago. The Tatcan Indians, a Bay Miwok tribe closely connected to the Saclans of Walnut Creek, lived in Alamo in the eighteenth century.
After Mission San José was founded in 1797, its grazing area stretched throughout the San Ramon Valley. The Mexican land grant Rancho San Ramon was deeded to Mariano Castro and his uncle Bartolo Pacheco in 1833. It covered modern-day Danville and Alamo. Castro owned the northern half, which included Alamo.
In 1843 much of the Alamo, Las Trampas and Tice Valley areas were granted to brothers Inocencio and José Romero. It was called Rancho El Sobrante de San Ramon. Because of missing title papers, the brothers lost their ranch in American courts in 1857.
Pioneers Mary Ann and John Jones traveled through Alamo in 1847. She provided the earliest English description of the area in her diary. Her husband stopped the wagon saying, "Mary, look! Did you ever see anything so beautiful?" She wrote later:
On every side, the valley and surrounding hills were covered with thick, velvety clover, and with wild oats standing waist high waving and rippling in the summer breeze, like the bosom of a lake.
The Jones family returned to Alamo in 1851, after California had become a state. John became the first postmaster in 1852 and she applied her considerable energies to schooling children and beginning a Cumberland Presbyterian church. Other early Alamo founders included David Glass, George Engelmeyer, Silas and Susanna Stone, Captain Wall, Joshua Bollinger, and James Foster.
The area was named Alamo, which comes from the Spanish word álamo, meaning "poplar" or "cottonwood." Alamo was named after the Alamo Mission in San Antonio. Because of its location and climate, Alamo grew quickly. An early road from the redwoods near Moraga ran through Tice Valley to Alamo, since Americans preferred redwood for building materials instead of Mexican adobe brick.
The Hemme, Bollinger, Jones and Stone ranches began by grazing cattle and raising wheat and other grains. In 1891 the Hemme train station was placed near today's Hemme Avenue; later it was renamed the Alamo station.
Eventually orchards and vineyards spread across the area. Almonds, walnuts, pears, grapes and other fruit thrived in the temperate climate. In 1873, Alamo pioneer Myron Hall grafted Persian cuttings to native walnut trees and helped start the prosperous walnut industry in Contra Costa County. This "mother tree" was tended for over 100 years.
The Alamo post office is the oldest continuously operated one in the valley. It was always an important community gathering place. According to longtime postmaster Bertha Linhares, when the mail was expected the men
sat in the post office-store in the winter … the women went into our sitting room and visited with my mother … We always heard all the news and troubles of the Alamo residents.[ citation needed ]
Her father, brother and sister were also postmasters from 1905 to 1960.
Alamo is located in Contra Costa County, at the northern end of the 20 miles (32 km)-long San Ramon Valley between two Coast Ranges − the Las Trampas Ridge to the west and the Diablo Range to the east.[ citation needed ] The city of San Ramon and the town of Danville are also located in this valley. Just to the north of Alamo lies the city of Walnut Creek. San Francisco and San Jose lie 28 miles (45 km) to the west and 46 miles (74 km) to the south, respectively.[ citation needed ] A few miles to the east of Alamo stands the 3,864 feet (1,178 m)-tall Mount Diablo.
According to the United States Census Bureau, the CDP has a total area of 9.7 square miles (25 km2), all of it land.
Alamo experiences a warm-summer Mediterranean climate with hot, dry summers and cool, rainy winters. Summer high temperatures are hot, but due to the high degree of seasonal diurnal temperature variation, the mean temperature remains low enough to qualify as a warm-summer Mediterranean climate, staying below 71.6 °F (22.0 °C). Temperatures occasionally reach 100 °F (38 °C) or higher in the warmest months, and frost occurs on some clear mornings during the coldest months.[ citation needed ] There are, on average 42 days per annum with at least 0.1 inches (2.5 mm) of rain (days when it is considered useful to carry an umbrella). During cold winter storms, snow can fall on top of nearby Mount Diablo, but very seldom falls in the Valley.
On July 6, 2017 at 3:44 pm until January 9, 2018, the Cal Fire reported that the Alamo Fire occurred.

Before the cattle ranch, the site was a summer camp for San Francisco orphans, known as Camp Swain. The property was purchased in 1874 by Captain Isaac and Ann Trasker Swain on behalf of an orphanage in San Francisco. The Swains thought the children should have a warm place to go during San Francisco's damp summers. In 1911 the San Francisco Protestant Orphanage first brought their children to Camp Swain. The orphans came to the valley from 1911 to 1952, using the train and then buses. There is a drinking fountain commemorating Camp Swain with a plaque and a brick rendering of children playing.
