AAH - Frequently Asked Questions

The Adopt-a-Highway (AAH) Program provides an avenue for individuals, organizations, and businesses to help maintain sections of the highway. Thanks to the newly created Clean California program, Caltrans is providing a stipend of up to $250 total per litter clean-up event, whether completed by an individual or group.
Interested parties can contact the Caltrans AAH program via phone by calling 866-ADOPTAHWY (886-236-7824), via email at AAH.HQ@dot.ca.gov or by filling out an online application at CleanCA.com.
The Clean California program includes $30 million over 3 years for the AAH stipend. The stipend component will end June 30, 2024, or when Caltrans distributes all the funds to volunteers, whichever comes first.
Caltrans is piloting the stipend program in the following counties: Butte, Colusa, El Dorado, Glenn, Imperial, Nevada, Placer, Sacramento, San Diego, Sierra, Yolo and Yuba, then will launch the stipends statewide in the coming months.
Caltrans chose these counties within Districts 3 and 11 due to their robust AAH programs and ability to process stipends.
Following a litter clean-up, Caltrans requires the volunteer to submit by email to the local District AAH Coordinator their group name, adopted site name, date of litter clean-up event, number of bags collected, number of workers, hours worked and picture of collected bags.
Individuals, organizations, and businesses, whether new or current volunteers, are eligible for the stipends. State employees and their families are welcome to participate in the AAH program but are not eligible to receive stipends.
The stipends will be issued monthly during the pilot, then quarterly starting in January 2022 by the State Controller’s Office. Depending on the State Controller’s Office, the department will send payment within 30-45 days after volunteers submit proof of litter removal.
Whether the litter clean-up event is completed by an individual or group, adopters are eligible to receive a maximum of one payment per month. The maximum stipends issued per location are set by the frequency specified on the encroachment permit. Additional clean-ups are welcome but not eligible for the stipend. Payments are subject to verification of litter clean-ups.
Caltrans will report the payments to the IRS for tax purposes.
