The minimum age is 11 years old, and there is no maximum age.
Groups adopt at least a two-mile stretch of highway for a minimum of two years.
At the end of the two-year period, the group can renew their commitment to the AAH program or withdraw. The AAH coordinator will know if the particular stretch of highway your group would like to adopt is available. If not, they will help you select an alternate site. City streets can not be adopted through the AAH program. The AAH program not only reduces the cost, but also helps convince the participants and other community members not to litter.
