Litter control.

(1) The Department of Transportation shall establish an “adopt-a-highway” program to allow local organizations to be identified with specific highway cleanup and highway beautification projects authorized under s. 339.2405. The department shall monitor compliance with the provisions of the adopt-a-highway program to ensure that organizations participating in the program comply with the goals identified by the department.

(2) The Department of Transportation shall place signs discouraging litter at all off-ramps of the interstate highway system in the state. The department shall place other highway signs as necessary to discourage littering.

(3) Each county is encouraged to initiate a litter control and prevention program or to expand upon its existing program. The department shall establish a system of grants for municipalities and counties to implement litter control and prevention programs. In addition to the activities described in subsection (1), such grants shall at a minimum be used for litter cleanup, grassroots educational programs involving litter removal and prevention, and the placement of litter and recycling receptacles. Counties are encouraged to form working public private partnerships as authorized under this section to implement litter control and prevention programs at the community level. Counties that have a population under 100,000 are encouraged to develop a regional approach to administering and coordinating their litter control and prevention programs.
