Plumber in Highland Park, CA

The area was settled thousands of years ago by Paleo-Indians, and would later be settled by the Tongva. After the founding of Los Angeles in 1781, the Corporal of the Guard at the Mission San Gabriel Arcángel, Jose Maria Verdugo, was granted the 36,403 acre Rancho San Rafael which included present day Highland Park. Drought in the mid-19th century resulted in economic hardship for the Verdugo family, which eventually compelled them to auction off Rancho San Rafael in 1869 for $3,500 over an unpaid loan. The San Rafael tract was purchased by Andrew Glassell and Albert J. Chapman, who leased it out to sheep herders. In 1885, during the 1880s land boom, it was sold to George Morgan and Albert Judson, who combined it with other parcels they had purchased from the Verdugo family to create the Highland Park tract in 1886. Two rail lines were built to Highland Park, which later helped the town to survive the burst of the property bubble. Highland Park was annexed to Los Angeles in 1895. In the early 20th century, Highland Park and neighboring Pasadena became enclaves for artists and intellectuals who were adherents of the Arts and Crafts movement.

With the completion of Arroyo Seco Parkway in 1940, Highland Park began to experience white flight, losing residents to the Mid-Wilshire district and newer neighborhoods in Temple City and in the San Fernando Valley. By the mid-1960s, it was becoming a largely Latino district. Mexican immigrants and their American-born children began owning and renting in Highland Park, with its schools and parks becoming places where residents debated over how to fight discrimination and advance civil rights.

In the final decades of the 20th century, portions of Highland Park suffered waves of gang violence as a consequence of the Avenues street gang claiming them and the adjacent neighborhood of Glassell Park as its territory. At the beginning of the 21st century, then City Attorney Rocky Delgadillo, a Highland Park native, intensified efforts to rid Northeast Los Angeles of the Avenues. In 2006, four members of the gang were convicted of violating federal hate crime laws. In June 2009, police launched a major raid against the gang, rooting out many leaders of the gang with a federal racketeering indictment, demolishing the gang’s Glassell Park stronghold. Law enforcement, coupled with community awareness efforts such as the annual Peace in the Northeast March, have led to a drastic decrease in violent crime in the 2010s.
