Taken together with those commuting into the Bay, incomes and employment for residents of the area are strong. These firms, from chemical to biotech to small manufacturers, have sprung up in the open valleys mainly in Vacaville and east and have created a lot of employment. A number of commercial and industrial enterprises have spread into Fairfield and especially the Vacaville area to escape (but still serve) the Bay Area. East across a narrow range of mountains, the land flattens again into the towns of Cordelia, Suisun City and the larger Fairfield and Vacaville.įairfield was once primarily a military town supporting Travis Air Force Base, which is still an important part of the local economy. The string starts with Vallejo (once a gritty port and navy town), which has transformed as a result of Bay Area crowding and high home prices into a fairly desirable commuter community. This area, known also as Solano County, is really a series of residential communities strung along I-80 as it heads east from the San Francisco Bay Area.
