Shadelands Ranch was established by Hiram Penniman, an early American settler of California in 1856 as one of the first and largest farms in California's Ygnacio Valley.Penniman arrived in California in 1853 and three years later purchased 500 acres (2.0 km2) of land from Encarnación Pacheco, daughter of Juana Sanchez de Pacheco, then owner of Rancho Arroyo de Las Nueces y Bolbones from which the 500 acres (2.0 km2) were taken.Penniman planted a variety of fruit and nuts, including peaches, pears, apricots, grapes, almonds, and walnuts, as well as prunes, which served as Penniman's most important and most profitable crop. The original name of Penniman's ranch was "Shadelands Fruit Farm". Hiram Penniman fell ill in January 1897 and care and oversight of the ranch became largely the responsibility of Penniman's oldest daughter, Mary. The ranch fell on hard times with a drop in the price of crops and Mary had to depend on the charity of her sister Bessie's wealthy husband to take care of many of the ranch's financial concerns.When Hiram finally died, ownership of the ranch passed to Mary, then subsequently to Bessie after Mary's death in 1909. Bessie and her husband Albert Johnson mainly managed the ranch from afar, as Albert's business concerns lay mainly in distant Chicago. In 1921, Bessie hired Edmund Moyer to reside at the ranch with his family and supervise it. Bessie died in 1943 in a car accident, and not long after, Albert himself became severely ill. In 1947, with an eye to his own mortality, Albert Johnson formed the Gospel Foundation, an organization meant to oversee his extensive assets after his death. Johnson died in 1948 of cancer, and deeded all his property to the Gospel Foundation, including Shadelands.The Gospel Foundation continued to administer Shadelands until 1970, when they gave the remaining 1.5 acres (6,100 m2) of land and the ranch house to the city of Walnut Creek, California. Today it is managed by the Walnut Creek Historical Society, and has been open to the public since 1972 as a historical museum, the ranch house still furnished with much of the Pennimans' original furniture. The house was placed on the National Register of Historic Places in 1985.

Concord Naval Weapons Station was a military base established in 1942 north of the city of Concord, California at the shore of the Sacramento River where it widens into Suisun Bay. The station functioned as a World War II armament storage depot, supplying ships at Port Chicago. During World War II it also had a Naval Outlying Field at the southern edge of the base. It ceased being an operating airfield after World War II. During the Korean War, the Vietnam War and the Gulf War, Concord NWS processed and shipped thousands of tons of materiel out across the Pacific Ocean.The station consisted of two areas: the Inland Area (5,028 acres (2,035 ha)), which is within the Concord city limits, and the Tidal Area (7,630 acres (3,088 ha)). Because of changes in military operations, parts of the Inland Area began to be mothballed, and by 1999 the station had only a minimal contingent of military personnel and contained mainly empty ammunition storage bunkers, empty warehouses, and disused support structures. In 2007, the U.S. federal government announced that the Inland Area of the Naval station would be closed. The Tidal area of the base was not scheduled for closure and reorganized as Military Ocean Terminal Concord (MOTCO). The 834th Transportation Battalion is the port manager at MOTCO and operates the three piers and an Army-owned rail system that connects with major public railway lines.The 5-member City Council of Concord, sitting as the federally designated Local Reuse Authority, is in the process of formulating a Reuse Plan for the Inland Area that includes residential and commercial development while reserving approximately two-thirds for open-space and parks projects. City staff are assigned to manage this effort. The Reuse Plan is subject to approval by the Navy.The East Bay Regional Park District will be receiving 2,540 acres (1028 hectares) of the Inland Area that will be developed for public use as Concord Hills Regional Park. Formal conveyance of the property was expected in early 2016 whereupon the property will be prepared for public access and recreation. Since then 2,216 acres were transferred from Navy property to park. In addition "2,300 acres will be transferred to the city of Concord, whose Concord Community Reuse Project has been overseeing planning for housing, businesses, a college campus and other development.".

The Pavilion has a capacity of 12,500 people and opened in 1975 as the Concord Pavilion. It is used for concerts, local community events (including an annual jazz festival) and local high school graduations. The Pavilion was designed by architect Frank Gehry and landscape architect Peter Walker. Gehry also designed its mid-1990s renovations, which included more parking and seats. The venue has hosted numerous professional musical acts over the years of its operation and continues to do so to this day. Bing Crosby played his last US concert at the Pavilion on August 16, 1977. Lawrence Welk's appearance at the Concord Pavilion on June 13, 1982, was billed as his farewell performance. Legendary concert promoter Bill Graham was killed in a 1991 helicopter crash after leaving a concert at the Pavilion by Huey Lewis and the News, having just discussed with the band about organizing a benefit for the victims of that year's fire in the Oakland Hills; Graham's production company, Bill Graham Presents (BGP), had been the booking agent for the Concord Pavilion since at least 1985.In a deal with the city of Concord, Bill Graham Presents took over operations of the facility in February 2000. Shortly thereafter, its name was changed to the Chronicle Pavilion at Concord, following the purchase of the naming rights by the business agent of the San Francisco Chronicle, the San Francisco Newspaper Agency. BGP was purchased in 2000, along with its parent, SFX Promotions, by Clear Channel Communications; in 2005, Clear Channel would spin off its concert operations into Live Nation, which operates the Pavilion to this day. The Pavilion changed its name in April 2006, when it became the Sleep Train Pavilion after the California-based mattress retailer (now a Houston, Texas-based company) purchased the naming rights; by 2017 the retailer folded into Mattress Firm.In December 2013, as part of a 10-year contract renewal between Venue Nation (previously known as Live Nation) and the City of Concord, the Pavilion's name was changed again to the Concord Pavilion.On August 3, 2023, the Pavilion was renamed Toyota Pavilion at Concord after the local Northern California Toyota Dealers Association, which consists of 58 local Toyota dealers operating in the northern half of the state, purchased the naming rights. The First Battle of the Bands for high school, middle school, and elementary school students took place in 2006 and the winner was a high school band, Poster Boy.
