Metropolitan Transportation Planning

What is an MPO?

A Metropolitan Planning Organization (MPO) is an organization of elected officials in urbanized regions with 50,000 or more population. MPOs provide a forum for local decision-making on transportation issues of a regional nature. Under SAFETEA-LU, the policy for the metropolitan planning process is to promote consistency between transportation improvements and state and local planned growth and economic development patterns.

As a condition for receipt of federal capital or operating assistance, MPOs must have a continuing, cooperative, and comprehensive transportation planning process. MPOs are to cooperate with the state in developing transportation plans and programs for the urbanized area (UZAs). This transportation planning process is to result in plans and programs consistent with the UZA’s comprehensive planned development. In addition, the plans are to provide for the development of transportation facilities (including pedestrian walkways and bicycle facilities) and serve as an intermodal system for the state, metropolitan areas, and the nation.

The MPO’s planning functions are carried out in cooperation with state and local agencies. An MPO can contract staff from other agencies to perform specific elements in the planning process. This cooperative transportation decision-making process provides a forum for member jurisdictions to discuss regional transportation issues and plan transportation improvements for the region.

Unified Planning Work Program (UPWP)

The MPOs and RTPOs are responsible for developing a Unified Planning Work Program (UPWP). The UPWP covers a one or two fiscal year period and includes transportation planning priorities facing the metropolitan and/or regional area.

In order for the MPOs to be eligible for federal planning funds, to accomplish the work elements in their UPWP, the Federal Highway Administration (FHWA) and the Federal Transit Administration (FTA) must first approve (pdf 244 kb) the MPOs' UPWP.

Transportation Improvement Program (TIP)

Transportation Improvement Program (TIP) Amendments are reviewed monthly for fiscal constraint by WSDOT’s Strategic Planning and Programming Division, Highways and Local Programs Division, and Public Transportation Division. They are then approved by the Secretary of Transportation for inclusion into the TIP. The projects in the Governor approved TIP (pdf 136 kb) are included in the STIP that are approved (pdf 227 kb) by the Federal Highway Administration and the Federal Transit Administration.

Relationship to Regional Transportation Planning Organizations (RTPOs)

In 1990, the Washington State Legislature passed the Growth Management Act (GMA) authorizing the Regional Transportation Planning Program. This program, contained in Part 3 of the Act (RCW 47,80), created a formal mechanism for local governments and the state to coordinate transportation planning for regional transportation facilities. The Act authorized the creation of Regional Transportation Planning Organizations (RTPOs). This transportation planning mechanism is available to all counties and cities statewide and is formed through voluntary association of local governments within a county or within geographically contiguous counties.

As RTPOs are the same organization as the designated MPOs, this integrates the RTPO Program with the MPO Program in UZAs. The RTPO Program extends transportation planning by MPOs to rural areas currently not covered by the federal program. The WSDOT administers these two programs jointly, without duplication.

The GMA requires the RTPOs to create a transportation policy board. The board’s primary function is to provide policy direction to the MPO/RTPO and to have representation of major transportation employers within the region. Once the RTPO is designated, it designates a lead-planning agency to staff the RTPO. The lead agency may be a regional council; a county, a city, or town agency; or a WSDOT office.

The minimum state requirement mandates RTPOs have representation by all counties within the region and 60 percent of the cities and towns.
