Signal Hill, California

Signal Hill is a city 2.2 mi2 in area in Los Angeles County, California. Located high on a hill, the city is an enclave completely surrounded by the city of Long Beach. Signal Hill was incorporated on April 22, 1924, roughly three years after oil was discovered there. As of the 2010 census, the city population was 11,016.

Etymology
Signal Hill was originally known as Los Cerritos (“The Little Hills") but got its current name when it became the signal point of the United States Coast and Geodetic Survey in 1889.

History
The hill that the city is named after is 365 feet (110 m) above the surrounding town of Long Beach. Because of this height, it was used by the local Tongva Indians for signal fires that could be seen throughout the surrounding area and even out to Catalina Island, 26 mi away.

After the Spanish claimed Alta 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. The Rancho San Pedro (Dominguez Rancho) land grant exceeded 74000 acre as granted to a soldier, Juan Jose Dominguez, who accompanied Junipero Serra, by Governor Fages through authority of King Carlos III of Spain 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 and Fatty 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.

Discovery of oil
Signal Hill changed forever when oil was discovered. The hill would soon become part of the Long Beach Oil Field, one of the most productive oil fields in the world. On June 23, 1921, Royal Dutch Shell's Alamitos #1 well erupted. The gas pressure was so great the gusher rose 114 ft (35 m) in the air. Soon Signal Hill was covered with over 100 oil derricks, and because of its prickly appearance at a distance became known as "Porcupine Hill". Today, many of the original oil wells and pumpjacks 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.
