Transportation efficient communities
WSDOT and the departments of Commerce, Ecology and Health together support local government efforts to make well-organized systems for travel and land use. Transportation Efficient Communities reviews best practices, contact information for subject matter experts, issue briefs and recorded webinars on land use, transportation, and healthy and safe communities.
