Hacienda Heights is an affluent census-designated place in Los Angeles County, California, United States. As of the 2010 census, the community had a total population of 54,038, up from 53,122 at the 2000 census. During Spanish rule, Hacienda Heights was a part of Rancho La Puente, which was operated by the nearby Mission San Gabriel Arcángel in San Gabriel.
Originally an agricultural town, beginning in the 1940s and accelerating in the 1950s, suburban residential development, which occurred southward (beginning on subdivisions near Kwis Avenue), transformed Hacienda Heights into a residential or bedroom community. In 1961, the Hacienda Heights Branch of the Los Angeles County Public Library opened. The following year, in 1961, the area was renamed Hacienda Heights. In 1964, the local newspaper, the Hacienda Heights Highlander, was established.
Hacienda Heights is located in the eastern San Gabriel Valley bordering City of Industry and West Covina to the North, Whittier to the West, La Habra Heights to the South, and Rowland Heights to the East along the Pomona Freeway – Route 60. Hacienda Heights is a predominantly residential neighborhood.
The “Puente Hills Landfill Native Habitat Preservation Authority” supports public enjoyment and access of the nearby parkland in the Puente Hills.
