Vacaville, California

Vacaville is a city in Solano County, California, on the edge of the Sacramento Valley in Northern California, about 35 miles from Sacramento and 55 miles from San Francisco. The city was founded in 1851 and is named after Juan Manuel Vaca. In the same year the Vaca and Pena families settled in the area of Lagoon Valley, and a written agreement signed on December 13, 1851 formed a township, with nine square miles of land deeded to William McDaniel for 3,000 dollars and the original city plans laid out from that. At the 2020 census Vacaville had a population of 102,386, making it the third largest city in Solano County. The unincorporated communities of Allendale and Elmira are generally considered part of greater Vacaville.
