Fire History
Solano County's fire risk is concentrated in its eastern hills and areas adjacent to the Napa and Sonoma county fire zones. The 2020 LNU Lightning Complex and Hennessey Fire burned along the county's northern and eastern borders. The Vaca Mountains between Solano and Napa counties represent the most fire-exposed terrain. Valley floor communities in Fairfield, Vacaville, and Vallejo have limited FHSZ exposure, but the eastern hillside communities of Vacaville and Winters area face real risk.
