Hacienda Heights, CA

Hacienda Heights helped turn a dispute over a regional landfill into a lasting open-space program. Residents opposed expansion of the Puente Hills Landfill in the hills beside the community. The resulting 1994 agreement created the Puente Hills Habitat Preservation Authority and directed one dollar from every ton of waste deposited at the landfill toward acquiring, restoring, and maintaining habitat. That fee supplied over $64 million before the landfill closed on October 31, 2013, after 56 years of operation. By 2024, the authority managed over 3,880 acres, had restored over 300 acres of native habitat, and maintained 23 miles of public trails. The preserved hills are tied directly to a long period when regional waste disposal and local opposition occupied the same landscape. The community below those hills began with a different land conversion.

In 1912, developers subdivided 1,826 acres of Rancho La Puente as North Whittier Heights for agricultural settlement. Citrus, walnut, and avocado orchards became defining crops before postwar housing replaced much of the farmland. The area adopted the name Hacienda Heights in 1961. It remains an unincorporated Los Angeles County community governed through county agencies. County planning places most commercial uses along Colima Road and Hacienda Boulevard, while the foothill edge rises south of the developed streets. The county regulates land use, while the Hacienda Heights Improvement Association holds a designated seat on the habitat authority's governing board. The Hacienda Hills section of the Puente Hills Preserve begins at a trailhead on Orange Grove Avenue.

Trails enter the steep, densely vegetated Puma, Toyon, and Coyote canyons, where coast live oak woodland and toyon-sumac chaparral grow on the slopes. An accessible path near the trailhead includes displays about a restored bioswale and habitat, while other routes climb deeper into the canyon network. These lands include areas transferred for permanent open-space protection after the landfill agreement. Their present use combines habitat management, environmental education, and low-impact recreation. The preserve is also a visible record of local civic action: dollars once collected from arriving waste now support the canyons and trail system overlooking the San Gabriel Valley. A different landmark occupies another Hacienda Heights hillside. Hsi Lai Temple is the first major overseas branch built by the Fo Guang Shan Buddhist order and the first imperial-style temple the order constructed outside Asia.

Its name means “coming to the west,” reflecting its purpose as a center for Humanistic Buddhism and Chinese culture. Construction received approval on May 31, 1985 after years of public hearings and neighborhood meetings. Groundbreaking followed in 1986, the main shrine opened in July 1988, and the full temple was inaugurated that November. The complex supports worship, meditation, education, charity, interfaith work, lectures, cultural arts, and an art gallery. Lunar New Year observances and other public programs bring visitors to the hillside through the year. From the developed valley, the temple complex and protected canyons present two enduring outcomes of community decisions about what the Puente Hills would hold.
