Tri-Valley

Understand

Location The Tri-Valley is in the East Bay region of California, consisting of these valleys:

Livermore Valley - the main valley of the Tri-Valley, which includes Pleasanton, Dublin, and Livermore Amador Valley - section of the Livermore Valley around the Stoneridge Mall area San Ramon Valley - to the north of the Amador Valley, the San Ramon Valley includes the city of San Ramon

People Although Tri-Valley is quite densely populated, the mountainous terrain around it is almost uninhabited.

History In the 1800s, European settlement of the region began with some unimportant buildings in the Dublin area. In 1850, Pleasanton became the first incorporated city in the region. Then, in 1869, Livermore became the second. In 1982-83, Dublin, San Ramon, and Danville also became incorporated. The movie industry came to the area in the early 1900s (in particular Pleasanton), but it moved completely to Southern California once talkies began to dominate.

Climate The area, due to its Mediterranean climate, is good wine country. Vineyards are abundant in the south side of the Tri-Valley.

Getting there

I-580, I-680, and CA-84 highways go to the region. These roads, however, can be become very busy at almost any time of year. The Altamont Commuter Express has a train station in Pleasanton, and BART has a station at the edge of Pleasanton and Dublin.

Getting around

There are major roads around the area, making travel relatively easy. There are two freeways (interstate highways), the I-580 and the I-680, along with a California State Route, the CA-84. The Iron Horse Trail biking and walking path goes through the Tri-Valley.
