Until the 1760s, the area that is now the city of Tracy was long populated by the Yokuts tribe of loosely associated bands of Americans Indians and their ancestors. They lived on hunting and gathering foods, game and fish from the area, including its local rivers and creeks. After encountering the Spanish colonists, the Yokuts suffered from new infectious diseases, which caused social disruption, as did the Spanish efforts to impress them for labor at missions. Mexican and American explorers later came into the area, pushing the Yokuts out. [10]

Tracy is a railroad town that came from the mid-19th century construction, mainly by Chinese laborers, of Central Pacific Railroad rail lines running from Sacramento through Stockton to the San Francisco Bay Area, beginning 1868 and ending September 1878 with the opening of a new branch and junction. [11] A number of small communities sprang up along these lines at designated station sites, including one at the junction named for railroad director J. J. Tracy. [12]

Incorporated in 1911, Tracy grew rapidly and prospered as the center of an agricultural area, even when larger railroad operations began to decline in the 1950s. Competition with trucking and automobiles resulted in widespread railroad restructuring. Tracy is part of the San Jose-San Francisco-Oakland, CA Combined Statistical Area, an extension of the Bay Area.

In December 1969, the town of Tracy was the host of the Altamont Free Concert, held at the (now closed) Altamont Raceway Park. An estimated 300,000 people gathered at the speedway infield in an event that was plagued by violence among attendees, many of whom were drunk or drugged. Artists featured included the internationally known Rolling Stones, Santana, Jefferson Airplane, The Flying Burrito Brothers and Crosby, Stills, Nash & Young.

Located in the Greater Bay Area, Tracy is near both fertile and (due to a region of hills west of Tracy) infertile agricultural lands. Tracy has a Mediterranean climate.

Some of this land (in the east and mostly north of Tracy because of the moist Delta river system) has come under increasing development pressure. The San Francisco Bay Area's vigorous population growth has spilled over into the Tracy area as well as other locations, such as the new town of Mountain House. Tracy passed Measure A in 1990 in an attempt to contain and limit development.

In an effort to reduce environmental impacts of the city, it launched the Emerald Tracy Project in September 2009. City spokesman Matt Robinson said that if it succeeds, Tracy will be the second city after Riverside, California to satisfy the state's goal for sustainable communities.

Tire fire, south of Tracy

On August 7, 1998, a tire fire ignited at S.F. Royster's Tire Disposal south of Tracy at 29425 South MacArthur Drive, near Linne Road. The tire dump held more than 7 million illegally stored tires and was allowed to burn for over two years before it was extinguished. Allowing the fire to burn was considered to be a better way to avoid groundwater contamination than putting it out. [13] The cleanup of chemicals released by the fire cost $16.2 million. The chemicals were found to have contaminated groundwater in the region after all. [14] [15]


Tracy is marked by a semi-arid climate (Köppen BSh), with mild, moist winters and very hot and dry summers, displaying Mediterranean characteristics. December and January are the coolest months, and average around 47.1 °F (8.4 °C), and there are 19 nights with lows at or below freezing annually, with the coldest night of the year typically bottoming out below 30 °F (−1.1 °C). [16] July is the warmest month, averaging 76.4 °F (28.3 °C); normally, there are 18 days of 100 °F (37.8 °C)+ highs and 82 days of 90 °F (32.2 °C)+ highs. Average annual precipitation is around 12.5 inches (317.7 mm), which, by definition, results in the area being classified as a semi-desert.
