Transportation Improvement Plans (TIP)

GHCOG provides technical assistance and training on TIP requirements and development, processes all amendments and forwards project information to SW Washington Regional Transportation Planning Organization (RTPO) and Washington State Department of Transportation (WSDOT). In order to maintain funding eligibility transportation projects must be included in local, regional and state TIP’s, which are adopted and updated by each jurisdiction or sponsoring agency.
