The Growth Management Act (GMA) requires the transportation element to implement and be consistent with the land use element. Counties and cities should use consistent land use assumptions, population forecasts, and planning periods for both elements. Coordination of the land use and transportation elements should be dynamic and iterative. There should be an ongoing feedback loop coordinating land use and transportation in the plan development and in local implementation. The transportation element is also required to be consistent with state and regional plans.
The transportation element is certified by the regional transportation organization to ensure consistency with the regional transportation plan.
Concurrency
Under the GMA, concurrency is one of 14 goals local governments must consider in land use planning. Concurrency is intended to ensure public facilities and services are adequate to serve new development at the time of occupancy without decreasing service levels below locally established minimum standards.
