, 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.
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.
The Pioneer period
The Pioneer, or 'American,’ period in Simi Valley began with the 96,000-acre purchase of El Rancho Simí by an eastern speculator named
Thomas A. Scott (1814–1882), who had made his money as an investor in the Pennsylvania Railroad during the Civil War. He was president of the
Pennsylvania Railroad
The Pennsylvania Railroad (reporting mark PRR), legal name The Pennsylvania Railroad Company also known as the "Pennsy", was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. It was named ...
, 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.
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 prospered longer here than in the rest of the county because it was free of a disease called "rust". Barley soon became the really successful 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.
Modern residential development
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 doubled to 8,110 in 1960. By 1970 the population in Simi is reported by the census as 59,832.
Four communities of Simi Valley 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, but then the name reverted to Simi). 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 the 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 the
Santa 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 the very first 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. It truly was a 'community center.'
Mortimer Park (the Susana knolls) – The area that is now the Knolls was a nearly 1,800-acre parcel of land 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, however, 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.
