Scope your Project
During the Project Scoping phase, WSDOT staff define projects by entering information into the WSDOT Project Summary Database. This process defines the purpose and need for the project, identifies and evaluates alternatives, and documents the overall scope and cost of the project. This information allows WSDOT and the legislature to prioritize projects for funding.
For scoping permits, go to the Federal, State, and Local Permits web pages.
