# Rancho Cucamonga, California

Rancho Cucamonga (/ˌræntʃoʊ kuːkəˈmʌŋɡə/ RAN-choh KOO-kə-MUNG-gə) is a city located just south of the foothills of the San Gabriel Mountains and Angeles National Forest in San Bernardino County, California, United States. About 37 mi (60 km) east of Downtown Los Angeles, Rancho Cucamonga is the 28th most populous city in California. The city's seal, which centers on a cluster of grapes, alludes to the city's agricultural history including wine-making. The city's proximity to major transportation hubs, airports, and highways has attracted the business of several large corporations, including Coca-Cola, Frito-Lay, Big Lots, Mercury Insurance Group, Southern California Edison, and Amphastar Pharmaceuticals.
The city had a population of 174,453 according to the 2020 United States census.
The Jack Benny Program popularized the city's name, in particular the word "Cucamonga".

## History

By 1200 AD, Kukamongan Native Americans had established a village settlement in the area around present-day Red Hill, near the city's western border, where Red Hill Country Club stands today. Kukamonga derives its name from a Tongva word meaning "sandy place." Anthropologists have determined that this cluster of settlers likely belonged to the Tongva people or Kich people, at one time one of the largest concentrations of Native American peoples on the North American continent. In the 18th century, following an expedition led by Gaspar de Portola, the land was incorporated into the Mission System established by Father Junipero Serra and his group of soldiers and Franciscan friars.
After a half century of political jockeying in the region, the land finally came under the control of Juan Bautista Alvarado, governor of Mexico. On March 3, 1839, Alvarado granted 13,000 acres (5,300 ha) of land in the area called "Cucamonga" to Tubercio Tapia, a first-generation Spanish native of Los Angeles, successful merchant, and notorious smuggler. Tapia went on to establish the first winery in California on his newly deeded land. Rancho Cucamonga was purchased by John Rains and his wife in 1858. The Rains family's home, Casa de Rancho Cucamonga, was completed in 1860 and now appears on the National Register of Historic Places.
During the ensuing years the town prospered and grew. In 1887, irrigation tunnels were dug into Cucamonga Canyon by Chinese laborers and the Santa Fe Railroad was extended through the area. Among the town's economic mainstays was agriculture, including olives, peaches, citrus, and, most notably, vineyards. In 1913, the Pacific Electric Railway was extended through Rancho Cucamonga in an effort to improve crop transportation. Several landmarks in existence today pay tribute to the city's multicultural founding. In particular, Our Lady of Mt. Carmel remains as a relic of the area's Mexican agriculture laborers while the Chinatown House stands as a reminder of the Chinese immigrants who labored in constructing the area's infrastructure.
In 1977, the unincorporated communities of Alta Loma, Cucamonga, and Etiwanda voted to incorporate, forming the city of Rancho Cucamonga.

### Grapeland

The former community of Grapeland, first settled in 1869, lay roughly between today's Victoria Groves Park and Central Park. There was a schoolhouse which also doubled as a church. In 1890 an irrigation district was formed and $200,000 in bonds were sold to pay for improvements. The Sierra Vista reservoir was built in 1886-87 by J.L. Scofield as the focal point of a network of irrigation pipes. The system was unused, however, because the bond issue was declared illegal. "Orchards and vineyards began to die," The Daily Report newspaper reported in a retrospective. "Residents moved out. The post office closed in 1905. Homes, buildings were destroyed or abandoned." The reservoir remained unused until 1956, when the Fontana Union Water Company filled it with 5 million US gal (19 million L) of water. The local school district was merged with the Etiwanda district in 1901. In 1957 the settlement was practically deserted, but there were still rabbit-proof stone walls marking boundaries of previous citrus orchards.

## Geography

## Economy

While most of the city's land area is devoted to residential areas, Rancho Cucamonga, like its neighbors Ontario and Fontana, is a major center for the logistics industry in Southern California. This is due to its proximity to two interstate highways and Ontario International Airport, and the space afforded by the large tracts of former agricultural land in the southern section of the city.
In the area around Milliken Avenue, between Archibald and Etiwanda Avenues, Foothill Boulevard, and Fourth Street, about seven square miles of land are primarily occupied by numerous massive distribution centers, and even more, smaller manufacturing companies. This area is ringed by office parks, mostly along Haven Avenue, and shopping strips, such as the Terra Vista Town Center (part of a nearly two-square-mile master-planned community in the center of the city), and malls, such as Victoria Gardens, and the Ontario Mills, across Fourth Street in Ontario.
The city is also home to a CMC Steel (formerly Gerdau, formerly TAMCO Steel) minimill, the only producer of long steel in California. This mill recycles ferrous scrap, such as junked cars and appliances, to produce rebar.
The city hosts LoanMart Field (formerly known as The Epicenter), a minor-league baseball stadium, home of the Rancho Cucamonga Quakes. The Quakes' mascot, Tremor, is a "Rallysaurus."

### Victoria Gardens

Victoria Gardens is a lifestyle center near the eastern end of the city, at the intersection of Foothill and Day Creek Boulevards. Since the city had never developed a traditional commercial downtown like neighboring cities Ontario and Upland had, efforts were made in the design of Victoria Gardens to bring elements of more traditional and urban town design to what had historically been a suburban city. While retaining many characteristics of traditional shopping malls, such as large anchor stores, a food court, and vast parking lots and garages, the smaller stores are arranged as city blocks in a grid of two-lane streets, featuring lush landscaping and metered "teaser parking" in front of the stores, which open onto the sidewalk. There are two "Main Streets", which run from west to east across the center. Running from north to south between them is a pedestrian axis leading from one of the Macy's anchor stores, through a "town square" between a pair of mixed-use office buildings, to the Victoria Gardens Cultural Center, which contains the Lewis Playhouse (a 570-seat theater) and a branch of the city library. The east side of the development has Southern California's first Bass Pro Shops Outdoor World superstore; the 180,000-square-foot (17,000 m$^2$) facility includes a Tracker Boat Center and the Islamorada Fish Company restaurant. There are restaurants throughout the center, both well-known chains and unique eateries. The center also features a 12-screen movie theater.

## Infrastructure
### Transportation

Rancho Cucamonga is served by Omnitrans bus service, train service from Metrolink's Rancho Cucamonga station on the San Bernardino Line, and nearby Ontario International Airport, one of four major Los Angeles-area passenger airports with multiple daily flights by most domestic carriers as well as a major shipping hub for companies like UPS and FedEx.
Rancho Cucamonga has been identified as the initial western end-point of the Brightline West High Speed Rail (HSR) project to connect Southern California with Las Vegas. On December 5, 2023, it was announced that the project would be awarded a grant of USD3 Billion from the Bipartisan Infrastructure Law.
Interstate 15 (I-15) and State Route 210 (SR-210) run through Rancho Cucamonga as well as the historic U.S. Route 66 (as Foothill Boulevard).
I-15 sits atop an elevated berm, and cuts a curve through the southeastern part of the city, isolating a mostly industrial area, a small shopping center, and several housing tracts from the larger part of the city. Further north, I-15 forms part of the northeastern border with neighboring Fontana before entering the Cajon Pass through the San Gabriel Mountains. I-15 provides connectivity with the High Desert, Nevada, and points north for the Inland Empire and much of Southern California.

### Utilities

Rancho Cucamonga receives natural gas from the Southern California Gas Company. The city's water supply and sewage are managed by the Cucamonga Valley Water District. Garbage collection is by Burrtec Disposal, phone service is from Frontier Communications and cable TV is provided by Charter Communications.
Electric power in Rancho Cucamonga is provided by Southern California Edison and the Rancho Cucamonga Municipal Utility.
Before 2024, the city was home to the Reliant Energy Etiwanda Generating Station, on Etiwanda Avenue. This facility, one of five Reliant stations in California, was a natural gas-fired power plant, which began operation in 1963. At 640 MW (860,000 hp) net capacity, it was Reliant's second-highest-capacity plant on the West Coast. It utilized four steam turbine generators; of which units three and four remained active after turbines one and two, as well as a combustion turbine, were retired in 2003 and 2004, respectively. Several systems are in place to control gas emissions, and annually, over 900,000,000 US gal (750,000,000 imp gal; 3.4 GL) of recycled water are used for cooling. As of 2024, all turbines and stacks and the entire electrical plant have been removed.
On November 29, 2011, the Inland Empire Utilities Agency installed the first wind turbine in Rancho Cucamonga.

## In popular culture

The name "Cucamonga" became well known to fans of Jack Benny's popular radio program, in which an announcer, voiced by Mel Blanc, would call out: "Train leaving on track five for Anaheim, Azusa and Cu-camonga!" This running gag became so well known that it eventually led to a statue of Benny in Cucamonga.
The city is the primary setting of the TV series Workaholics and the feature film Next Friday. Further mention of the city was made in the Netflix series Unsolved.
The city was claimed as the location where the "Flamin' Hot" flavor of Cheetos was created in the 1980s at the Frito-Lay factory.
Cucamonga is referenced in the Grateful Dead song "Pride of Cucamonga" on the album From the Mars Hotel, and in "Cucamonga" on Frank Zappa's album Bongo Fury.
