District 12 Adopt-A-Highway Program

The Adopt-A-Highway program provides an avenue for individuals, organizations, or businesses to help maintain sections of roadside within California's State Highway System. Groups have the option to participate as volunteers or to hire a maintenance service provider to perform the work on their behalf.

Since 1989, the Adopt-A-Highway program has been one of the truly successful government-public partnerships of our time. More than 120,000 Californians have cleaned and enhanced over 15,000 shoulder-miles of roadside.

Participation can include one or more of the following activities:

  • Removing litter (work frequency varies with location)
  • Planting and establishing trees or wildflowers
  • Removing graffiti
  • Controlling vegetation

Adoptions usually span a two-mile stretch of roadside and permits are issued for five-year periods. Groups in good standing may renew their permits indefinitely. Participation is free for all volunteers and signs are included at no charge. Contractors charge fees for their services.
