Oak Park Unified School District

The Simi Hills are a low rocky mountain range of the Transverse Ranges in eastern Ventura County and western Los Angeles County, of southern California, United States.

Atomics International was a division of the North American Aviation company (later acquired by the Rockwell International company) which engaged principally in the early development of nuclear technology and nuclear reactors for both commercial and government applications. Atomics International was responsible for a number of accomplishments relating to nuclear energy: design, construction and operation of the first nuclear reactor in California (1952), the first nuclear reactor to produce power for a commercial power grid in the United States (1957) and the first nuclear reactor launched into outer space by the United States (1965).Atomics International undertook the development of nuclear reactors soon after being established: a series of commercial nuclear power reactors beginning with the Sodium Reactor Experiment (SRE) and a range of compact nuclear reactors culminating with the Systems for Auxiliary Nuclear Power SNAP-10A system. Both efforts were successful, despite nuclear accidents at the Santa Susana Field Laboratory, but overall interest in nuclear power steadily declined. The division transitioned to non-nuclear energy-related projects such as coal gasification and gradually ceased designing and testing nuclear reactors. Atomics International was eventually merged with another division (Rocketdyne division) of the same parent company (Rockwell International). As of 2010, all of the Atomics International facilities, except for the few remaining facilities located in the Area IV test area at the Santa Susana Field Laboratory (SSFL), have been demolished, cleaned and reused, or awaiting final cleanup.

The Upper Las Virgenes Canyon Open Space Preserve is a large open space nature preserve owned and operated by the Santa Monica Mountains Conservancy spanning nearly 3,000 acres (1,200 ha) in the Simi Hills of western Los Angeles County and eastern Ventura County. Originally part of Ahmanson Ranch, this area was sold by Seattle-based Washington Mutual to the Santa Monica Mountains Conservancy in late 2003 after lengthy issues concerning development in the chaparral shrub forest and oak savanna understory and overstory Plant communities. It was previously called Ahmanson Ranch Park.

Brent's Delicatessen & Restaurant is a Jewish deli and restaurant located in Northridge, California. The restaurant was opened in 1967 and purchased by Ron Peskin in 1969 for $1700. The deli has expanded to a second location in Westlake Village, California.

The Energy Technology Engineering Center (ETEC), was a government-owned, contractor-operated complex of industrial facilities located within the 2,850-acre (11.5 km2) Santa Susana Field Laboratory (SSFL), Ventura County, California. The ETEC specialized in non-nuclear testing of components which were designed to transfer heat from a nuclear reactor using liquid metals instead of water or gas. The center operated from 1966 to 1998. The ETEC site has been closed and is now undergoing building removal and environmental remediation by the U.S. Department of Energy.

The Sodium Reactor Experiment was a pioneering nuclear power plant built by Atomics International at the Santa Susana Field Laboratory near Simi Valley, California. The reactor operated from 1957 to 1964. On July 12, 1957 the Sodium Reactor Experiment became the first nuclear reactor in California to produce electrical power for a commercial power grid by powering the nearby city of Moorpark. In July 1959, the reactor experienced a partial meltdown when 13 of the reactor's 43 fuel elements partially melted, and a controlled release of radioactive gas into the atmosphere occurred. The reactor was repaired and restarted in September 1960. In February 1964, the Sodium Reactor Experiment was in operation for the last time. Removal of the deactivated reactor was completed in 1981. Technical analyses of the 1959 incident have produced contrasting conclusions regarding the types and quantities of radioactive materials released. Members of the neighboring communities have expressed concerns about the possible impacts on their health and environment from the incident. In August 2009, 50 years after the occurrence, the Department of Energy hosted a community workshop to discuss the 1959 incident.

Oak Park is an unincorporated community in southeastern Ventura County, California, United States. When developed in the Simi Hills in the late 1960s, a single road provided the only access to the community from Agoura Hills, California, in neighboring Los Angeles County. As of the 2010 census, Oak Park had a population of 14,266, down from 14,625 at the 2000 census. For statistical purposes, the United States Census Bureau has defined Oak Park as a census-designated place (CDP). The census definition of the area may not precisely correspond to local understanding of the area with the same name. Oak Park is the biggest unincorporated community in Ventura County. Residents of the community have through votes declined to set up an independent city, and also declined to be annexed into neighboring Thousand Oaks.

China Flat is a plateau in the north−central Simi Hills, in Ventura County, Southern California.The plateau sits at a 2,000 feet (610 m) elevation and is situated just below Simi Peak, which is the highest point in the Simi Hills.

Oak Park High School (abbreviated OPHS) is the main high school in the Oak Park Unified School District, taking ninth through twelfth grade students. It is a National Blue Ribbon School and a 2019 California Distinguished School, and received an Exemplary Distinction Award from the California of Education for its Career and Technical Education program which includes career pathways in Engineering Design, Media Arts, Production Management, and construction technologies. The 2012 Academic Performance Index (API) was 929, which is among the highest in California. In 2015 the school was awarded the California Gold Ribbon School Award from the California Department of Education. The 2016 Newsweek Ranking of America's Top Schools ranked Oak Park High as #51 in the nation and #7 in CA.

Bell Canyon is an unincorporated community in eastern Ventura County, California, United States. Bell Canyon is a gated community in the Simi Hills with the main access through the Los Angeles community of West Hills and the western San Fernando Valley. Bell Canyon sits at an elevation of 1,368 feet (417 m). The 2020 census reported Bell Canyon's population was 1,946. For statistical purposes, the Census Bureau has defined Bell Canyon as a census-designated place (CDP). According to a 2016 study, Bell Canyon is the seventh wealthiest community in the state of California with an annual median income of $230,000.

The Santa Susana Field Laboratory (SSFL), formerly known as Rocketdyne, is a complex of industrial research and development facilities located on a 2,668-acre (1,080 ha) portion of Southern California in an unincorporated area of Ventura County in the Simi Hills between Simi Valley and Los Angeles. The site is located approximately 18 miles (29 km) northwest of Hollywood and approximately 30 miles (48 km) northwest of Downtown Los Angeles. Sage Ranch Park is adjacent on part of the northern boundary and the community of Bell Canyon is along the entire southern boundary.SSFL was used mainly for the development and testing of liquid-propellant rocket engines for the United States space program from 1949 to 2006, nuclear reactors from 1953 to 1980 and the operation of a U.S. government-sponsored liquid metals research center from 1966 to 1998. Throughout the years, about ten low-power nuclear reactors operated at SSFL, (including the Sodium Reactor Experiment, the first reactor in the United States to generate electrical power for a commercial grid, and the first commercial power plant in the world to experience a partial core meltdown) in addition to several "critical facilities" that helped develop nuclear science and applications. At least four of the ten nuclear reactors had accidents during their operation. The reactors located on the grounds of SSFL were considered experimental, and therefore had no containment structures. The site ceased research and development operations in 2006. The years of rocket testing, nuclear reactor testing, and liquid metal research have left the site "significantly contaminated". Environmental cleanup is ongoing. The public who live near the site have strongly urged a thorough cleanup of the site, citing cases of long term illnesses, including cancer cases at rates they claim are higher than normal. On 30 March 2018, a seven-year-old girl living in Simi Valley died of neuroblastoma, prompting public urging to thoroughly clean up the site. Experts have said, however, that there is insufficient evidence to identify an explicit link between cancer rates and radioactive contamination in the area.
