Solano County, California
Solano County sits between the Bay Area and Sacramento, with Vallejo and Benicia on the strait, Fairfield and Vacaville on Interstate 80, and Travis Air Force Base as a major employer. It retains more developable land than most Bay Area counties, but the voter-approved Orderly Growth Initiative, Travis's airfield compatibility zones, and Suisun Marsh protections keep growth tightly inside existing city limits.
