Walnut is an affluent city in Los Angeles County, California, United States. The population was 29,172 at the 2010 census and its current mayor is Tom King, a former Detective from the Los Angeles Police Department.
The city of Walnut obtained its name from the Rancho Los Nogales Mexican land grant, nogales being the Spanish word for "walnut." With exceptions to some busy intersections (such as Grand avenue and Amar near Mt. San Antonio College), the hill-dotted city is relatively quiet in comparison to nearby neighborhoods like La Puente and West Covina. The city covers nearly nine square miles (23 km2) and is home to hundreds of businesses.
Walnut is located in the San Jose Hills and is home to several small creeks that run throughout local parks (i.e. Snow Creek, Lemon Creek).
The history of Walnut dates back to the Indians who were of Shoshone origin. They were called "Gabrielino Indians" by the Spaniards, who arrived in the early 19th century, because the Indians lived in an area controlled by the San Gabriel Mission. Walnut was primarily used for the grazing of cattle and sheep by the Mission. The city of Walnut got its name from the nut, walnut.
The first Mexican land grants in the Walnut area were those of 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. The land was used for raising cattle and growing wheat, grapes, and fruit trees.
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 1871, 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 Family Festival 
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.
Mt. SAC Relays 
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. The current world record in the 4x200 metres relay, 1:18.68, set by the Santa Monica Track Club (Michael Marsh, Leroy Burrell, Floyd Heard, Carl Lewis) was set April 17, 1994 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 
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. In March 2009, Walnut filed a lawsuit opposing construction of the stadium, but dropped those charges in September.
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. This bill would also nullify a lawsuit filed by local residents over the project's environmental impact report.
