Vallejo Watershed Alliance


The Vallejo Watershed Alliance is a community-based group working together to improve the greater Vallejo watershed, which encompasses the City of Vallejo and nearby unincorporated areas of Solano County.

The Alliance is made up of interested residents, local groups and agencies including representatives from the Vallejo Sanitation & Flood Control District, the Greater Vallejo Recreation District, the California Native Plant Society and others. Their mission is to raise awareness, create local partnerships and promote sustainable management of Vallejo’s watersheds.

The Alliance hosts monthly workdays, planning meetings, and other activities.
