Signal Hill is acity 2.2 sq mi (5.7 km2) in area inLos Angeles County, California. Partially high on an eponymous hill, the city is anenclave completely surrounded by the city ofLong Beach. Signal Hill wasincorporated on April 22, 1924, roughly three years afteroil was discovered there. As of the2020 census, the population was 11,848, up from 11,016 at the2010 census.
Signal Hill was originally known asLos Cerritos ("The Little Hills") but got its current name when it became the signal point of theUnited States Coast and Geodetic Survey in 1889.[6]
The hill that the city is named after is 365 feet (111 m) above the surrounding city of Long Beach. Because of this height, it was used by the localTongvaIndians forsignal fires that could be seen throughout the surrounding area and even out toCatalina Island, 26 miles (42 km) away.[7]
After the Spanish claimedAlta California ("Upper California," or what is now the state of California), Signal Hill eventually became part of the first large rancho grant to be allotted under Spanish rule in Alta California. TheRancho San Pedro (Dominguez Rancho) land grant exceeded 74,000 acres (300 km2) as granted to a soldier,Juan Jose Dominguez, who accompanied Junipero Serra, by Governor Fages through authority ofKing Carlos III ofSpain in 1784.
Between 1913 and 1923 an early California movie studio,Balboa Amusement Producing Company (also known as Balboa Studios), was located in Long Beach and used 11 acres (45,000 m2) on Signal Hill for outdoor locations.Buster Keaton andFatty Arbuckle were two of the Balboa Studios actors who had films shot on Signal Hill.
Before oil was discovered in Signal Hill, there were large homes built on the hill itself, and in the lower elevations there were agricultural fields where fruits, vegetables, and flowers were grown.
Signal Hill changed forever when oil was discovered. The hill would soon become part of theLong Beach Oil Field, one of the most productiveoil fields in the world.[8] On June 23, 1921,Royal Dutch Shell'sAlamitos #1 well[9] erupted. Thegas pressure was so great thegusher rose 114 ft (35 m) in the air. Soon Signal Hill was covered with over 100oil derricks, and because of its prickly appearance at a distance became known as "Porcupine Hill". Today, many of the original oil wells andpumpjacks are gone, although Signal Hill is still a productive oil field and several wells and derricks remain. Signal Hill is now a mix of residential and commercial areas.
The city was incorporated on April 22, 1924. Among the reasons for incorporation was avoiding annexation by Long Beach with its zoning restrictions and per-barrel oil tax. Proving to be a progressive city, Signal Hill elected as its first mayor, Mrs. Jessie Nelson. She was California's first female mayor.
Signal Hill has a council-manager form of government. The city council has five members who are elected to four-year, staggered terms; council members elect the mayor from among their ranks.
The Signal Hill Police Department provides local law enforcement.[13] In 2018, it budgeted for 38 police officers to enforce the law in the 2 square mile municipality.[14]
