In high growth areas, highways frequently become congested as the result of land use changes. Local land use controls have not prevented the adverse impacts. Further, state funds are inadequate to address the critical problems in growth areas.
This study investigates six study areas in Washington State to compare land use change impacts and the effectiveness of the various procedures applied to prevent or correct such problems and to fund highway improvements in growth areas. A survey of practice in other states provides information concerning their approaches to the problem.
The study concludes that comprehensive land use planning supported by inter-agency cooperation has been limited. Local governments have applied a number of innovative techniques for financing local roads and streets. Cooperative interagency planning before growth is out of control has benefited both the local jurisdiction and the state. However, state and local jurisdictions lack the authority to apply these techniques to state highways in Washington State. The study makes recommendations for increasing interagency cooperation and for legislative remedies.
