The project aims to provide guidance for roadside vegetation management that identifies and quantifies the cost, safety, and environmental impacts of routine mowing compared with managed succession of vegetation for areas outside the safety clear zone. Managed succession is based on a strategic approach of selective control measures that utilize a combination of zero maintenance, targeted mowing, mechanical trimming and removal, and chemical and/or biological treatments. Some benefits may include ecosystem diversity, stormwater quantity and quality management, carbon sequestration, erosion control, pollinator corridor development, wildlife habitat, and aesthetics.
