Section 5: Mowing and Litter Pickup

Anchor: #i1002902

Guideline

Litter pickup operations should be conducted before mowing operations.

Anchor: #i1002914

Explanation

Mowing a littered portion of right of way would:

Anchor: #FEPJDECW
• increase the risk of the mowers striking unseen objects and causing harm to people, machinery and passing traffic
Anchor: #GJXPRYJJ
• cause shredding of large pieces of litter, resulting in more time consuming litter pickup operations
Anchor: #YNUYVFCB
• expose more litter to view.
