The CTDOT considers the care of trees and vegetation within the state right of way (ROW) a high priority. Trees statewide are still being severely stressed by several factors. Notably Emerald Ash Borer, Spongy Moth infestations, Beech Leaf Disease, drought conditions and the Spotted Lanternfly have severely impacted Connecticut vegetation.
Within the highway ROW there needs to be a designated clear zone. This clear zone provides an un-obstructed, impact free buffer or clear area for vehicles which may unintentionally exit the roadway. There may also be certain dead, diseased, or leaning trees that are outside of this clear zone which need to be removed due to their potential of impacting the travel lanes
CTDOT is continuing to prioritize areas statewide using state forces, contracted tree crews and specialized equipment to address roadside vegetation and re-establish safety clear zones. Supervisors and Vegetation Management Specialists establish cutting limits in relation to abutting property or environmentally sensitive areas. Reviews for proposed linear Vegetation Management Safety Improvement (VMSI) projects as well as work being performed within designated scenic roads are conducted in advance prior to any work being performed. This review is performed by specialized personnel, namely a Vegetation Management Supervisor (VMS) and an Environmental Planner (CMEP) who are trained to identify vegetation conditions and environmental concerns. The VMS and the CMEP assist crews with identifying vegetation removal within and directly adjacent to environmentally sensitive areas. These areas may include but are not limited to watercourse crossings, wetlands, aquifer protection areas, watersheds, areas containing endangered, threatened, and special concern species, as well as areas containing scenic/historical resources. Best Management Practices (BMPs) are implemented when working within and directly adjacent to environmentally sensitive areas.
Established clear zones also create roadside succession of vegetation, which promotes pollinator habitat within the right of way. The CTDOT has an established Pollinator Program which creates pollinator habitat areas within the ROW. In 2024 the program consisted of 147 Conservation Areas comprising approximately 239 acres statewide with additional areas added annually.
The CTDOT is completely committed to the safety of the motoring public and the efficiency of the state’s transportation network. At the same time, the CTDOT understands the aesthetic and environmental value of healthy vegetation and trees. As such, the CTDOT will continue to make reasonable efforts to preserve trees and aesthetic appeal providing safety will not be compromised by doing so.
