Roadside Vegetation Management Plans

Area maintenance crews use roadside vegetation management plans to determine the most appropriate tools, techniques and timing, for accomplishing prioritized roadside maintenance activities. These plans, once developed, become the basis of an ongoing process of refinement and crew training, using annually documented experience of each area’s proven success and lessons learned. This is an open process and WSDOT encourages input at any time from the general public, its neighbors, and/or any other statewide or local interests.

The plans include geographic inventories of routine maintenance activities, weed infestations, sensitive areas, and other relevant information. They also include a record-keeping system and database to document, evaluate and reference site-specific treatments, various situations and types of vegetation.

Roadside vegetation management plans have been developed and implemented throughout much of the state. Individual plans may be accessed from the active links below.

WSDOT welcomes public review and comment on these plans and all other aspects of roadside vegetation management at any time.
