What is an RTPO, why were they created and what
do they do?

Regional Transportation Planning Organizations (RTPO) are formed by voluntary associations of local governments within geographically contiguous counties. RTPO members may include cities, counties, WSDOT, tribes, ports transportation service providers, and private employers.

RTPOs were authorized as part of the 1990 Growth Management Act to ensure local and regional coordination of transportation plans.

RTPO planning must involve cities, counties, WSDOT, transit agencies, ports, and private employers. Among other duties individual RTPOs may perform to serve their membership, RTPOs are required to:

  • Prepare a Regional Transportation Plan
  • Certify that countywide planning policies and transportation elements of local comprehensive plans are consistent with the Regional Transportation Plan
  • Develop a six-year Regional Transportation Improvement Program

Who are RTPOs?

There are 14 RTPOs covering 38 of the 39 counties in Washington. San Juan County is not part of any RTPO.

How are RTPOs different than Metropolitan Planning Organizations (MPO)?


  • Created by state legislation (GMA) and supported by state funding
  • Covers both urban and rural areas


  • Created by federal legislation and supported by federal funding
  • Covers urbanized areas only

MPOs and RTPOs serve the same basic transportation planning functions – develop a long-range plan, coordinate within a region, and prepare a transportation improvement program. The federal MPO and state RTPO requirements of these organizations are complementary. The lead agency for a RTPO is also the lead agency for the MPO within the region (except Lewis-Clark Valley MPO because it is a bi-state organization.)
