Castaic, California

99 Oaks is an archaic placename of the Santa Clarita Valley, Los Angeles County, California in the United States. The location was mainly a rest stop between Castaic and Castaic Junction in what was then a fairly remote location along Old Highway 99. Otis and Macy Andrews opened the 99 Oaks Café in 1936. Circa 1950, 99 Oaks had a service station and a café. The name 99 Oaks was later used for buildings nearby, such as 99 Oaks Auto Court in Mint Canyon, 99 Oaks Cabins in Castaic, and the 99 Oaks Car Lot in Newhall. What little there was of 99 Oaks "mostly disappeared" when Route 99 was replaced by Interstate 5 in 1968.

North County Correctional Facility (NCCF) is a Los Angeles County jail, run by the Los Angeles County Sheriff's Department. Located approximately 40 miles (64 km) northwest of downtown Los Angeles, it is one of four jails located within the Pitchess Detention Center (named after former Sheriff Peter J. Pitchess), in Castaic, California. The facility's construction began in 1985, and it was formally dedicated on March 1, 1990 by then Sheriff, Sherman Block, and the President of the United States, George H. W. Bush. NCCF consists of five jails within the same facility, and it has an inmate population of about 3,800. It can provide for disciplinary segregation and clinic-level medical treatment. The facility is commonly referred to as the "Flagship"; it was designed and constructed to be cost-efficient with regard to the ratio of staff members to inmates and vocational productivity. NCCF has a ratio of ten inmates to each staff member. The facility features educational, vocational and counseling programs. These programs have been designed to assist the facility's inmates in becoming self-sufficient within the law.

Peter J. Pitchess Detention Center, also known as Pitchess Detention Center or simply Pitchess, is an all-male county detention center and correctional facility named in honor of Peter J. Pitchess located directly east of exit 173 off Interstate 5 in the unincorporated community of Castaic in Los Angeles County, California. The 2,620-acre site was previously known as the Wayside Honor Rancho, Castaic Honor Farm, or the Wayside Jail (by which it is still sometimes known) and was nicknamed the Wayside Drunk Farm in the 1940s because of the large proportion of inmates serving time for alcohol-related offenses—when first built for prison use in 1938 it was a minimum-security facility where inmates worked on a farm setting. In 1983 it was renamed the Peter J. Pitchess Honor Rancho. All farming operations were terminated in 1992 and the "rancho" component of the center was closed altogether in 1995 because of budgetary constraints, at which point it acquired its current name. It is run by the Los Angeles County Sheriff's Department, and is divided into a North Facility, East Facility, South Facility, and North County Correctional Facility, each managed under different levels of prison security. In its current designation it was designed to house approximately 8,600 men either awaiting hearings or trial on a variety of crimes (i.e., "detention") or parole violators with sentences of up to one year ("corrections"), the two groups collectively termed "inmates". As of 1998 it was the county's largest jail complex. It is also the oldest operating jail in the county. The Municipal and Superior courthouses where Pitchess inmates are taken for hearings and trials include Van Nuys, San Fernando, Burbank, Pasadena, Newhall, Antelope Valley, Malibu, and downtown Los Angeles.

The Honor Rancho Oil Field (also Honor Rancho Natural Gas Storage Field, Honor Rancho Underground Storage Facility) is an approximately 600-acre oil field and natural gas storage facility in Los Angeles County, California, on the northern border of the Valencia neighborhood of Santa Clarita, near the junction of Interstate 5 and westbound California State Route 126. Discovered in 1950 and quickly developed, the field's oil production peaked in the 1950s, but remains productive in 2016. In 1975 Southern California Gas Company (SoCalGas), the gas utility serving Southern California, began using one of its depleted oil producing zones, the Wayside 13 zone, as a gas storage reservoir, and it became the second-largest in their inventory after the Aliso Canyon gas storage facility. The field shares part of its extent with the Peter J. Pitchess Detention Center, which includes a maximum-security prison. The only operators on the field as of 2016 were SoCalGas and Vintage Production California, LLC, a subsidiary of Occidental Petroleum. The field produced approximately 50,000 barrels of oil in 2014, and the capacity of the gas storage reservoir is about 26 billion cubic feet of natural gas. Forty gas injection wells tap into the reservoir.
