The legislature finds that while the transportation system in Washington is owned and operated by numerous public jurisdictions, it should function as one interconnected and coordinated system. Transportation planning, at all jurisdictional levels, should be coordinated with local comprehensive plans. Further, local jurisdictions and the state should cooperate to achieve both statewide and local transportation goals. To facilitate this coordination and cooperation among state and local jurisdictions, the legislature declares it to be in the state's interest to establish a coordinated planning program for regional transportation systems and facilities throughout the state.
