As with the entire Tri-Valley, agriculture was the basis for San Ramon economy until suburban development began. In 1966 the new Interstate 680 freeway was completed through San Ramon to Dublin. For years a sign “San Ramon Population 100” accurately reflected the number of people in the area, with the whole San Ramon Valley having just over 2000 people for many decades.
The designation “San Ramon Village” first appeared in the 1970 census with a count of 4,084 people, part of a San Ramon Valley population of 25,899. Developers Ken Volk and Bob McClain built the first San Ramon suburban homes close to the county line. A special district, the Valley Community Services district (VCSD) provided the water, parks, sewer, fire protection and garbage collection for the new homes.[raw]
