Roadside restoration is the use of planning, design, construction, and maintenance activities to restore roadside plant communities according to designated roadside character and Roadside Classification Plan provisions.

Roadside Restoration Resources
The Roadside Policy Manual coordinates and guides the management of Washington’s highway roadsides within a framework of roadside character classifications. It provides policy and criteria for roadside restoration and advocates the use of native plants, integrated vegetation management (IVM), and a long-term management approach to achieve sustainable roadsides.

The Roadside Manual establishes a common basis for consistent roadside management decisions statewide. It shows the links and coordination necessary between all WSDOT partners responsible for roadside activities. In addition, the manual supplements statewide roadside criteria established in the Roadside Classification Plan.

The Design Manual provides policies, procedures, and methods for developing and documenting the design improvements to the transportation network in Washington
