Redwood Empire Council is the local council of the Boy Scouts of America that serves youth in Mendocino and Sonoma counties in California. The Petaluma Area Council #041 (originally Petaluma Council) was founded in 1919, and served the cities/towns of Petaluma, Sonoma, Cotati, and adjacent unincorporated communities. In 1943, it expanded through a territory transfer with the Silverado Area Council (at this time adding Mendocino County and northern Sonoma County area). At that time, the PAC voted to rename itself the Sonoma-Mendocino Area Council.
