Blending identities as a bedroom community and major employment center, San Ramon's impressive growth over the past decade was the result of a single decision. When developers decided to transform 580 acres of orchards into Bishop Ranch Business Park in the 1980s, the complexion of the community changed. Today, over 16,500 people are employed at the park, serving as the regional headquarters for giants like Pacific Bell, Chevron, AT&T, ROLM, and IBM. Domestic and international companies agree that San Ramon has the right combination of "room to grow" and an excellent innovative environment. The dizzying pace of prime development has amazed long-time residents who still remember the days of driving to Danville for groceries. The construction of Interstate 680 further opened the area to waves of new subdivisions and commercial growth. Among its impressive amenities, San Ramon now claims several shopping centers, a hospital, library, community center and senior center, a golf course, country club, swimming pool and numerous parks. Fortunately, the transition from a residential and agricultural village into a bustling business center has been admirably planned and controlled to maintain a quality image. Parks, fountains, waterfalls, and acres of rolling lawns surround modern office buildings and industrial parks to create a truly beautiful living environment. East Bay regional recreational amenities are superb, providing thousands of acres of prime wilderness, trails, and nature preserves.
