Walnut is a suburban city in the eastern part of Los Angeles County in California.[8] Money's Best Places to Live ranked Walnut #70 in 2009[9] and #57 in 2011,[10] the highest ranking for a California city in both years.

The greater Walnut Valley is located between the steep San Jose Hills mountain range to the north, and the gentle Puente Hills to the south. Quality housing consists of master-planned single family homes ranging in size from 1,800 to 11,200 square feet. The city hosts a highly ranked public school system - the Walnut Valley Unified School District, which has been ranked by numerous sources as one of the top public school districts in Southern California[11] as well as Mt. San Antonio College. Walnut is one of the cities with the lowest crime rates in the San Gabriel Valley.[8]

The city covers nearly nine square miles (23 km2) and is home to hundreds of businesses. Its 2012 population was estimated at 29,661 by the United States Census Bureau. According to the 2010 United States Census, Walnut has a median household income at one of the top earning percentiles in the country at $101,250.[12]

The city's name is derived from the Rancho Los Nogales Mexican land grant, nogales being the Spanish word for "walnut trees". The native California black walnut is a common tree of the San Jose Hills. The City of Walnut is a general law city incorporated on January 19, 1959. It is governed by a city council/city manager form of government. A five-member city council is elected by the residents, and a mayor is elected annually by the council to serve a twelve-month term. A city manager is appointed by the council to oversee the daily activities of the city.


Walnut is located on the southern slopes of the San Jose Hills, with West Covina to the north and west, Pomona to the east, Diamond Bar, Rowland Heights, and the City of Industry to the south, and La Puente to the west. Several small creeks (i.e. Snow Creek, Lemon Creek) run mostly to the south toward the valley of San Jose Creek, which runs west to the San Gabriel River.


The history of Walnut dates back to the indigenous Tongva people. Spanish missionaries who arrived in the 18th century called the indigenes Gabrieleño, because the area where they lived was controlled by the San Gabriel Mission. The Walnut area was part of the network of outlying ranches used for the grazing of cattle and sheep by the Mission.

Following secularization of the missions in the 1830s, former mission lands were divided into ranchos, and given away as land grants by the Mexican government of Alta California. In the Walnut area, the first grants were Rancho San Jose (granted to Ricardo Vejar and Ygnacio Palomares in 1837); Rancho Los Nogales (granted to Jose De La Cruz Linares in 1840); and Rancho La Puente (granted to John Rowland and William Workman in 1842). In 1868, John Rowland and William Workman divided Rancho La Puente, leaving Rowland the eastern half and Workman the western half. Rowland’s land included the western portion of Walnut and the adjacent community now called Rowland Heights. The land was used mainly for raising cattle and growing wheat, grapes, and fruit trees (mostly citrus).

In 1895, the first U.S. post office was established and given the name "Lemon". In 1908, the post office name was changed to Walnut.[13] As a reminder of those early days, the U.S. Post Office is on Lemon Avenue, one of the town's main streets.

The City of Walnut’s Bicentennial Commission selected the construction of Lemon Creek Park and the restoration of the William R. Rowland Adobe Redwood Ranch House as Walnut’s bicentennial project. In 1872, the Lemon Creek Park area became the property of Sheriff William Rowland, who inherited the 29,000-acre (120 km2) ranch from his father, John Rowland. The modest structure built in 1883 served as the home of Mr. Meridith, ranch foreman for William Rowland. The adobe redwood ranch house is one of the few remaining original ranch style redwood and adobe structures in the area. On October 1, 1975, the State Landmark Committee placed the W.R. Rowland ranch house in the National Registry of Historical Places.

Walnut is sometimes confused with the city of Walnut Creek in Northern California.

Walnut Family Festival[edit]

Walnut holds an annual "Walnut Family Festival." On the day of festival, several streets in the area (such as portions of Lemon and La Puente) are closed in the morning and a parade is held in which many local clubs and groups participate. Later in the afternoon, a fair with booths, games, food, and activities is held in Suzanne Park, adjacent to Suzanne Middle School. The Walnut Family Festival usually occurs in early or mid-October.

Mt. SAC Relays[edit]

Olympic Flame and wall of honor at Hilmer Lodge Stadium

Started in 1959, the Mt. SAC Relays is an annual track and field festival held primarily at Hilmer Lodge Stadium on the Mt. San Antonio College campus. The April festival attracts many elite athletes from around the world to the city of Walnut. This meet and other elite track meets held at the stadium, including the 1968 Olympic Trials and two editions of the USA Outdoor Track and Field Championships have emblazoned the identification of "Walnut, California" in numerous national records in athletics around the world. At various points in time, many world records were set at the Mt. SAC Relays.

The October Mt. SAC Cross Country Invitational, run in the hills surrounding the stadium, proclaims itself to be the largest Cross Country meeting in the world. Much of the same course is used as the annual CIF Southern Section championships and the western qualifier for the Foot Locker Cross Country Championships.

Proposed NFL stadium[edit]

In April 2008, billionaire land developer and co-owner of the Los Angeles Lakers and Kings Edward P. Roski unveiled plans for the construction of an $800 million NFL stadium in the neighboring City of Industry.[51] In March 2009, Walnut filed a lawsuit opposing construction of the stadium, but dropped those charges in September.[52][53]

On October 23, 2009, California governor Arnold Schwarzenegger signed a bill allowing the 75,000-seat stadium to be built in neighboring Industry in hopes of attracting an NFL team there.[54] This bill would also nullify a lawsuit filed by local residents over the project's environmental impact report.
