Concord Jazz Festival

Toyota Pavilion at Concord (formerly known as Concord Pavilion) is an amphitheatre located in Concord, California. It is owned by the City of Concord and operated by Live Nation. 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.

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.".

Camp Stoneman was a United States Army facility located in Pittsburg, California. It served as a major troop staging area for and under the command of the San Francisco Port of Embarkation (SFPOE). The camp operated during World War II and the Korean War. The camp opened May 28, 1942 as a staging point for units deploying to the Pacific Ocean theater of World War II. The camp was named after George Stoneman, a cavalry commander during the American Civil War and Governor of California. It was decommissioned as a military post in 1954. The camp had a railroad track across the north side for receiving and shipping men. Late in the war the SFPOE experimented with embarking troops directly aboard a Liberty ship at the camp but that was not successful due to difficulties of large ship navigation to the camp. Next to the track, there were many buildings with loading docks, many of which were still there in 2017 along Bliss Avenue. There were seven barracks areas, each consisting of nine blocks (3 x 3) surrounding a mess hall. In addition to being a staging area for troops in transit, the Pacific Coast Transportation Corps Officer Training School was located at the camp. The camp also housed prisoners of war with the Italian Service Unit of the 18th Italian Quartermaster Service Company, which was based at the camp.
