Tribal and Regional Coordination

WSDOT provides oversight and fiduciary responsibilities for 12 federally designated Metropolitan Planning Organizations (MPOs) and 15 state Regional Transportation Planning Organizations (RTPOs).

Metropolitan and Regional Transportation Planning

  • Metropolitan Planning Organizations
    A Metropolitan Planning Organization (MPO) is an organization created and designated to carry out the metropolitan transportation planning programs in urbanized areas with 50,000 or more population. MPOs provide a forum for local decision making on transportation issues within the metropolitan planning area (MPA) boundary.
  • Regional Transportation Planning Organizations
    A Regional Transportation Planning Organization (RTPO) is formed through the voluntary association of local governments within a county or geographically contiguous counties to conduct regional transportation planning and programs. RTPO members include cities, counties, WSDOT, tribes, ports, transportation service providers, private employers, and others.
