Prior to the colonization of the area by theSpanish Empire in the late 18th century, theTongva village ofWapijanga (submerged by the building of thePrado Dam in 1941) was the major point of influence in what would later become Chino Hills. The village was an important point of connection between the Tongva and theSerrano. Another Tongva village,Pasinogna, was also located in present day Chino Hills[6][7]
In 1848, theCalifornia gold rush began inNorthern California. Meanwhile, inSouthern California, cattle ranchers made fortunes in the beef trade, feeding the influx of migrants. In 1858, Chino Hills became one of thestagecoach stations of theButterfield Overland Mail. In 1881, the land was sold to Richard Gird, a miner fromTombstone, Arizona, who had plans to develop the land. In 1893, after being impacted by economic depression, Gird was forced to sell the land to a group of real estate investors who developed the town ofChino, which was incorporated in 1910.[8] Around this time, a resort was opened atLa Vida Mineral Springs in Carbon Canyon, in the modern-daySleepy Hollow region of the city. In 1925, theLos Serranos Country Club opened. The area became a destination for both tourists and bootleggers during theprohibition era because of its relative isolation. For the same reason, Sleepy Hollow became a destination for hippies and artists during the 1960s.[9] As Southern California grew, suburban housing began replacing farmlands. Developers targeted Chino Hills for its scenic views and proximity to L.A. and Orange counties. During the late 1980s, the area experienced a surge of development, and an incorporation effort began. In 1991, the city of Chino Hills wasincorporated with a population of 42,000.[10]
Chino Hills is a part of theChino Valley. According to theUnited States Census Bureau, the city has a total area of 44.8 square miles (116 km2), much of which is undeveloped rolling hills, including theChino Hills State Park. 44.7 square miles (116 km2) of it is land and 0.1 square miles (0.26 km2) of it (0.15%) is water.
Due to its topography of rolling hills, Chino Hills was primarily rural prior to the mid-1970s; most land was utilized forequestrian purposes and fordairies, except for the multi-use purposes of the State of California, promoting jobs for the community throughday labor from the Chino Institute for Men on Central Avenue. Rapid and extensive housing developments followed throughout the 1980s and early 1990s, only slowing down in recent years. Most neighborhoods are arranged in a village-type format with strategically placed shopping centers and parks designed to be within walking distance of nearby homes. The Vellano Country Club, a private golf course and housing development, was designed by golf championGreg Norman, his first project in theGreater Los Angeles area.[11] Chino Hills also includes the developed golf course developmentneighborhood ofLos Serranos. Other large master-planned subdivisions includeWoodview/Village Crossing,Gordon Ranch,LaBand Village,Butterfield Ranch,[12]Rolling Ridge,Fairfield Ranch, andPayne Ranch.[13]
The city of Chino Hills is bounded by theLos Angeles County cities ofPomona andDiamond Bar to the north and to the northwest, the Los Angeles County unincorporated area ofSouth Diamond Bar to the west, theSan Bernardino County city ofChino to the east, unincorporatedRiverside County nearCorona to the southeast, and theOrange County cities ofBrea andYorba Linda to the west and southwest, respectively, as well as an unincorporated area of Orange County between Brea and Yorba Linda and a small unincorporated area between Yorba Linda andAnaheim, to the southwest and south, respectively.
The eastern border of Chino Hills roughly follows theChino Valley Freeway (SR 71), which offers access to thePomona Freeway (SR 60) to the north and theRiverside Freeway (SR 91) to the south. Undeveloped hills form the western border, which also serves as the San Bernardino – Orange County line. Because this area is mostly undeveloped, there is only one road directly connecting Chino Hills and Orange County,Carbon Canyon Road (SR 142), which is long, winding, and prone tolandslides.[14][15]
Chino Hills is situated near several significant fault lines due to its position within the complextectonic setting of theSan Andreas Fault system. The most prominent faults in the area include:
Chino Fault: This fault runs along the eastern edge of the Chino Hills, extending from Corona to the Los Serranos area.
Yorba Linda Fault (Yorba Linda Trend): This lesser-known fault identified in the 1990s transects the Whittier Fault and extends into the southeastern portion of Chino Hills.
Additionally, there are other active faults in the broader region, including theElsinore Fault Zone, which runs from the Peninsular Ranges northwest to the Chino Hills range.
These faults contribute to the seismic activity in the region, such as the 2008 Chino Hills earthquake, with a magnitude of 5.4, attributed to pressure at the intersection of the Chino and Whittier faults. The earthquake was felt as far south as San Diego and as far north as Las Vegas.
Chino Hills, California, has experienced several significant wildfires, including theFreeway Complex Fire andCanyon Fire, primarily due to dry conditions, strong winds, and dense vegetation. These events have led to increased awareness and preparedness efforts in Chino Hills and surrounding communities. Residents are encouraged to create defensible spaces around their properties, maintain fire-resistant landscaping, and stay informed about local fire conditions, especially during peak wildfire seasons.

Chino Hills follows the Council-Manager model of government.[3] The city is governed by a city council which establishes all city ordinances, approves plans, adopts budgets, etc. The council appoints the city manager who enforces laws and, in essence, runs the city's day-to-day operations.[27]
The city council is elected by city residents and, within the council, rotates the position of mayor. Once elected, the city council members serve a four-year term. The five city council members meet on the second and fourth Tuesday of each month, with opportunity for residents to voice their opinion during the open forum. The meetings are broadcast via the city's television station and streaming via the city's website.[3]
