Simi Valley's name is derived from the Chumash word Shimiyi, which refers to the stringy, thread-like clouds that typify theregion.[12][13][14] The name could have originated from the strands of mist from coastal fog that move into theOxnard Plain and wind their way up theCalleguas Creek and the Arroyo Las Posas into Simi Valley.[15] The origin of the name was preserved because of the work of the anthropologistJohn P. Harrington, whose brother, Robert E. Harrington lived in Simi Valley. Robert Harrington later explained the name:"The word Simiji in Indian meant the little white wind clouds so often seen when the wind blows up here and Indians living on the coast, would never venture up here when those wind clouds were in the sky. The word Simiji was constructed by whites to the word Simi. There are other explanations about the name Simi, but this one was given to me by my brother who worked over 40 years for theSmithsonian Institution and it seems most plausible to me".[16][17]
Three Chumash settlements existed in Simi Valley during the Mission period in the late 18th and early 19th century: Shimiyi, Ta'apu (present-dayTapo Canyon), and Kimishax or Quimicas (Happy Camp Canyon west ofMoorpark College).[18][19][20] There are many Chumash cave paintings in the area containing pictographs, including theBurro Flats Painted Cave in the Burro Flats area of theSimi Hills, located between the Simi Valley,West Hills, andBell Canyon. The cave is located on private land owned by NASA. Other areas containing Chumash Native American pictographs in the Simi Hills are by Lake Manor andChatsworth.[21]
The first Europeans to visit Simi Valley were members of the SpanishPortolá expedition (1769–1770), the first European land entry and exploration of the present-day state ofCalifornia. The expedition traversed the valley on January 13–14, 1770, traveling fromConejo Valley to San Fernando Valley. They camped near a native village in the valley on the 14th.[22]
Rancho Simí, also known as Rancho San José de Nuestra Señora de Altagracia y Simí,[23] was a 113,009-acre (457 km2)Spanish land grant in easternVentura and westernLos Angeles counties granted in 1795 to Santiago Pico. After Santiago Pico's death in 1815, the Rancho was regranted to Santiago's sons Javier Pico and his two brothers, Patricio Pico and Miguel Pico, members of the prominentPico family of California.[23]Rancho Simí was the earliest Spanish colonial land grant within Ventura andSanta Barbara Counties. The name derives fromShimiji, the name of theChumash Native American village here before the Spanish.[24] It was the largest Spanish or Mexican land grant given in Ventura County, and one of the largest given in California. TheSimi Adobe-Strathearn House, later the home of Robert P. Strathearn and family, served as the headquarters of the rancho.
José de la Guerra y Noriega, a Captain of theSanta Barbara Presidio, who had begun to acquire large amounts of land in California to raise cattle, purchased Rancho Simí from the Pico family in 1842. After Jose de la Guerra death in 1858, the sons of Jose de la Guerra continued to operate the ranchos. The end of their prosperity came when several years of drought in the 1860s caused heavy losses. In 1865, the De la Guerras lost the ownership of El Rancho Simí excluding the Rancho Tapo. El Rancho Tapo was part of the original 113,009-acre Rancho Simí grant, but sometime around 1820–1830, the Rancho Tapo came to be thought of as a separate place within Rancho Simí.[23] The last of the De la Guerras to live in Simí Valley retreated to a 14,400-acre portion of the original rancho that was known as the Tapo Rancho. As late as February 1877, Juan De la Guerra was reported in county newspapers to be preparing to plant walnuts in the Tapo, which appears to be the final mention of their farming in relation to the original Simí grant.
The De la Guerra heirs tried every legal means, but by the 1880s, the Rancho Tapo also slipped from their ownership, as had the rest of the Rancho.[23]
The Pioneer, or 'American,' period in Simi Valley began with the 96,000-acre purchase of El Rancho Simí by an eastern speculator namedThomas A. Scott (1814–1882), who had made his money as an investor in the Pennsylvania Railroad during the Civil War. He was president of thePennsylvania Railroad, and a partner in Philadelphia and California Petroleum Company. Scouts came to California to purchase lands, and thus Scott acquired El Rancho Simí (1865). His goal was to locate sites for oil, since the first oil well had been developed in Titusville, Pennsylvania just a few years earlier (1859). Within a short time, a 27-year-old man named Thomas Bard was sent west by Scott to manage the California properties. In the late 1880s, Simí Land and Water Company was formed to see to the selling of the huge rancho in ranch-size properties. Some American farmers had begun to lease land in the greater Rancho Simí for farming.[23][25]
The earliest Anglo American ranchers showed up in Simí Valley in the late 1860s into the 1870s. Charles Emerson Hoar was given the title of "first American farmer" by early Simí historian Janet Scott Cameron. He had purchased the Hummingbird's Nest Ranch in the northeast corner of the Valley, and he leased land from the new owners of the Simí Rancho for raising sheep, already a proven way of making a living.
Much of the Simí Rancho land continued, as in Spanish days, to be used for raising sheep, cattle and grain. Wheat was more likely to prosper here than in the rest of the county, being free ofwheat leaf rust, a fungal disease. Barley soon became the predominant grain crop.
Agriculture and ranching dominated the landscape through the 1950s. Citrus, walnuts and apricots were all grown in Simi Valley. In the early 1960s modern residential development began to take place.
When Simí was an agricultural community, there were ranch houses that dotted the Valley. Four distinct communities also were located in the Valley (see 'Four Communities of Simi Valley' section below) prior to modern residential development. Though 1957 and 1958 brought the first 'tract' housing developments when the Dennis and Ayhens, Wright Ranch and Valley Vista tracts were built, the tremendous 'boom' in residential development took place beginning in 1960. The population which was 4,073 in 1950[26] doubled to 8,110 in 1960.[27] By 1970 the population in Simi is reported by the census as 59,832.
Four communities prior to modern residential development
The pioneers arrived in the late 1860s – 1870s and ever since, this has been 'The Valley of Simi.' But, not all the communities in the valley were known as 'Simi.' There was the township of Simi (known as 'Simiopolis' for about a six-month period in 1888). In the valley there were also the communities of Santa Susana, Community Center and the Susana Knolls (known first as Mortimer Park) at different points in time.
Simi – In late 1887–1888, the incorporation of Simi Land and Water Company came about. El Rancho Simí was divided into ranches and farms by that corporation, and advertised for sale to midwestern and New England states. An investor group, the California Mutual Benefit Colony of Chicago, purchased land and laid out a townsite (located between First and Fifth Streets and from Los Angeles south to Ventura Ave), named it 'Simiopolis' and shipped twelve pre-cut, partially assembled houses from a lumberyard in Chicago via rail to Saticoy, then brought by wagon to Simi. These are known as 'colony houses.' This was the first 'neighborhood' in Simi. Stores sprung up on Los Angeles Ave, and the first Simi School was built in 1890 on Third and California Streets, and was used until Simi Elementary was built in the mid-1920s.
Santa Susana – In 1903 theSanta Susana Train Depot was built, and the railroad was complete through Simi Valley, except for the tunnel, which was completed in 1904. A small business community grew up near the Santa Susana Train Depot, which was located on the north side of Los Angeles Ave, just east of Tapo Street. Over time residential developments followed and the town of Santa Susana was born. The Depot was moved in 1975 by Rancho Simi Recreation and Park District to its current location off of Kuehner.
Community Center – In 1922 L.F. Roussey laid out the small development which became known as Community Center. The driving force behind this development was the need for a High School in Simi Valley, as well as an elementary school in a more central location in the valley. The first graduating class from Simi High School was 1924, Simi Elementary was completed in 1926, The Methodist Church (which is now the Cultural Arts Center) was built in 1924. Numerous houses were built in Community Center in the 1920s and 1930s. The Simi Valley Woman's Club was located there as well (the building which served as the clubhouse for the Woman's Club was moved from the town of Simi). The Woman's Club club house was used by many individuals and organizations as a community meeting place.
Mortimer Park (the Susana knolls) – The area that is now the Knolls was a nearly 1,800-acre parcel of land (730 ha) that was purchased by Mr. and Mrs. Lewis T. Mortimer in the early 1920s. They planned on selling the lots for cabins, or vacation homes. The lots were very small (30 x 50 feet), and the Mortimers did not take the mountainous nature of the land into account, so quite often the lots were not buildable. Oftentimes several lots were needed to build structures. In 1944 the Garden Club, an active community organization in the area petitioned the county supervisors to change the name of Mortimer Park to the Susana Knolls.
The first attempt to incorporate the towns of Simi, the area known as Community Center (93065) and Santa Susana (93063) in 1966 was unsuccessful. The second attempt in 1969 was successful, with residents voting 6,454 to 3,685 in favor of incorporation. 59% of eligible voters turned out for this vote. Susana Knolls is an unincorporated area of the Valley. Voters also voted whether to call this newly incorporated city 'Santa Susana' or 'Simi Valley.' The name Simi Valley garnered 2,000 more votes than Santa Susana.[28]
The 2,848 acres (1,153 ha)Santa Susana Field Laboratory located in theSimi Hills, was used for the development of pioneering nuclear reactors and rocket engines beginning in 1948. The site was operated byAtomics International andRocketdyne (originally both divisions of theNorth American Aviation company). The Rocketdyne division developed a variety ofliquid rocket engines. Rocket engine tests were frequently heard in Simi Valley. The Atomics International division of North American Aviation designed, built and operated theSodium Reactor Experiment, which in 1957 became the first United States commercialnuclear reactor to supply electricity to a public power system,[29] when it powered the city ofMoorpark (the government ownedBORAX-III reactor had previously poweredArco, Idaho for around an hour in 1955). The last nuclear reactor operated at SSFL in 1980 and the last rocket engine was produced in 2006. The SSFL has been closed to development and testing. The site is undergoing investigation and removal of the nuclear facilities and cleanup of the soil and groundwater. The Boeing Company, the US DOE, and NASA are responsible for the cleanup.[30][31]
In July 1959, theSodium Reactor Experiment suffered a serious incident when 13 of the reactor's 43 fuel elements partially melted resulting in the controlled release of radioactive gas to the atmosphere. The reactor was repaired and returned to operation in September 1960. The incident at the Sodium Reactor Experiment has been a source of controversy in the community. Technical analysis of the incident intended to support a lawsuit against the current landowner (The Boeing Company) asserts the incident caused the much greater release of radioactivity than the accident atThree Mile Island.[32] Boeing's technical response concludes the monitoring conducted at the time of the incident, shows only the allowable amount of radioactive gasses were released, and a Three Mile Island-scale release was not possible.[33] The case was settled, it is reported, with a large payment by Boeing. In September 2009, The U.S. Department of Energy sponsored apublic workshop where three nuclear reactor experts shared their independent analysis of the July 1959 incident.[34]
Simi Valley is a city located in the very southeast corner ofVentura County, bordering theSan Fernando Valley inLos Angeles County, and is a part of theGreater Los Angeles Area. The city of Simi Valley primarily consists of theeponymous valley itself.[36] The city of Simi Valley borders theSanta Susana Mountains to the north, theSimi Hills to the east and south, and is adjacent toThousand Oaks to the southwest andMoorpark to the west. Simi Valley is connected to the nearby San Fernando Valley by theSanta Susana Pass in the extreme east of Simi Valley. Thesyncline[37] Simi Valley is located in the western part of the region called theTransverse Ranges.[38] While the Santa Susana Mountains separate the valley from theLos Padres National Forest in the north, the Simi Hills separate it fromConejo Valley in the south. In the extreme east isRocky Peak, one of Santa Susana Mountains' highest peaks, which is a dividing line betweenVentura County to the west andLos Angeles County to the east. On the other side of the valley, in the extreme west side of Simi Valley isMount McCoy, which may be most known for its 12 ft. concrete cross that sits at its peak. The physiographical valley is a structural as well as atopographic depression.[39] The Simi Valley, just as neighboringSan Fernando Valley, owes its existence and shape to the faulting and folding of the rocks. It is essentially a structural valley and not wholly the work of erosion.[40] It is drained by theCalleguas Creek and also its principal tributary,Conejo Creek. Both of these originate in the Santa Susana Mountains.
According to the United States Census Bureau, the city has a total area of 42.2 sq mi (109.4 km2), comprising 41.5 sq mi (107.4 km2) of land and 0.77 sq mi (2.0 km2), or 1.81%, of it is water. Simi Valley is located northwest of the Los Angeles neighborhood ofChatsworth and approximately 30 mi (50 km) fromDowntown Los Angeles, 380 mi (610 km) south ofSan Francisco, 160 mi (260 km) north ofSan Diego, and 350 mi (560 km) south ofSacramento. Commutes to Los Angeles are usually via theState Route 118 (Ronald Reagan Freeway) or the Southern CaliforniaMetrolink commuter train, which makes several daily trips from Simi Valley. Simi Valley has amediterranean climate. Temperate variations between day and night tend to be relatively big. The mean annual temperature is 64.1 degrees (17.8 °C), while the annual precipitation is 18.39 inches (467 mm). The precipitation remains less than one inch for seven months – April until October, – while the precipitation exceeds four inches in the two wettest months – January and February. While the mean temperature is at its lowest at 53.6 degrees (12.0 °C) in December, the mean temperature in July and August exceeds 76 degrees (24 °C).[41]
Simi Valley has been the victim of several natural disasters, including the flood of 1967, the storm of 1983, the 1988 lightning strike, as well as the1994 Northridge earthquake and numerous wildfires.[28]
Simi Valley has a warm and dry climate during summer when mean temperatures tend to be in the 70s. Wildfires do also occur here. The city's climate cools during winter when mean temperatures tend to be in the 50s. Because of its relatively low elevation, theSimi Hills typically experience rainy, mild winters. Snow is rare in the Simi Hills, even in the highest areas. The warmest month of the year is August with an average maximum temperature of 96 °F (36 °C), while the coldest month of the year is December with an average minimum temperature of 38 °F (3 °C). Temperature variations between night and day tend to be relatively large during summer, with a difference that can reach 38 °F (21 °C), and moderate during winter with an average difference of 29 °F (16 °C). The annual average precipitation in Simi Valley is 17.9 inches. Winter months tend to be wetter than summer months. The wettest month of the year is February with an average rainfall of 4.8 inches. Simi Valley gets 18 inches of rain per year, while the United States average is 37. Snowfall is 0 inches, while the U.S. average is 25 inches of snow per year. The number of days with measurable precipitation is 25. On average, there are 277 sunny days in Simi Valley per year. The July high is approximately 96 °F (36 °C). The January low is 39 °F (4 °C).[42] The record low is 18 degrees Fahrenheit (−8 °C) (recorded in February 1989)[43] and the record high is 116 degrees Fahrenheit (47 °C) (recorded in August 1985).[43]
Wildfire in theSimi Hills, 2003. U.S. Air ForceC-130 Hercules pilots flew eightC-130 cargo airplanes and dropped 129,600 gallons of retardant on the fire.
An aspect of Simi Valley's location, situated beside theSimi Hills, is that it lies in a high-risk area for the wildfires that sweep through Southern California's mountain ranges every few years. Simi Valley is also at risk for earthquakes. The valley is surrounded byfaults; the closest ones being the Santa Rosa Fault to the Northwest, the Northridge Hills Fault to the Northeast, and the Chatsworth Fault to the South. In 1994, portions of Simi Valley received significant damage from theNorthridge earthquake.[45]
In autumn 2003, theSimi Fire burned about 108,000 acres. A 2005 fire started on September 28 and burned an estimated 7,000 acres (30 km2). On September 29, the fire was estimated to be 17,000 acres (70 km2). More than 1,000 firefighters worked against the tricky combination of dry brush, low humidity and temperatures in the high 90s along the line that divides Los Angeles and Ventura counties. The fire was later brought under control and extinguished, without serious injury. Three homes were lost in outlying areas, but none within the city limits.
Downtown/Los Angeles Avenue Corridor - The Envision Simi Valley Specific Plan[47][48] was created to provide a framework for mixed-use development to turn this portion of the city into a walkable area where people work and live.
Santa Susana - A portion of this neighborhood was included in the Envision Simi Valley Specific Plan, to creat as a framework for redevelopment into a secondary, smaller downtown.[48]
Simi Valley, California – Racial and Ethnic Composition Note: the US Census treats Hispanic/Latino as an ethnic category. This table excludes Latinos from the racial categories and assigns them to a separate category. Hispanics/Latinos may be of any race.
Before the 1960s, Simi Valley once boasted a strong community of Latino families, many of whom worked for white ranchers. However, the housing boom in the 1960s and 1970s attracted many white Americans leaving urban areas inLos Angeles and theSan Fernando Valley.[60] This turned Simi Valley into a predominately white city, but the percentage of those who identified as non-Hispanic white began to decrease from 86.2% in 1980 to 54% in 2020.

The popular 1970s television showLittle House on the Prairie utilized an expansive collection of sets constructed throughout the hilly landscapes ofBig Sky Ranch in theTapo Canyon hills north of Simi Valley andSanta Clarita, California. In addition to the Little House itself, the entire set for the town of Walnut Grove was built atop the hills. After finishing his work on the series,Michael Landon blew up the town (which became part of the final movie)[111] but the Little House itself was left intact. In July 2004, the house was destroyed by a devastating California wildfire.[112]

^1950 Census of Population. Tabular census data included Moorpark (1,146) as part of Simí Township for a total of 5,219
^Note: In 1960 the Census reported a population of Simí Township as 4,417. This was inclusive of Simí (2,107) and Santa Susana (2,310). The source for this 1960 population figure is the Ventura County Planning Department (VCPD) data. The 1960 population number as reported by the VCPD is a little less than double when compared to the Census figure. This is likely due to the different geographical areas which were included in the count. Census data included Santa Susana and Simí, while the table below is an example of the areas which the VCPD included – Burro Flats (Knolls), Santa Susana, Simí Urban (town of Simí), Tripas-Tapo (area north of Santa Susana). It is unclear where Community Center was categorized. Due to the differential between the Census and the VCPD population numbers, it needs to be considered that, though a good indicator of growth, the population numbers prior to 1960 may be under-representing the population of Simí.
