Local Transit Authorities and Funding Sources

This page provides an overview of public transportation benefit areas and other types of local government transit authorities in Washington State, including enabling statutes, funding sources, transit development plans, and a list of transit agencies.

This page lists local government transit agencies only and does not list other public transportation providers such as tribal or community transportation services.


As of 2020, there are 32 local government transit agencies in Washington State, most of which are operated as public transportation benefit areas (PTBAs) or other special purpose districts. A few are directly operated by cities or counties. Below is the breakdown:

  • 21 public transportation benefit areas
  • 6 city transit departments
  • 3 county public transportation authorities
  • 1 metropolitan county transit agency
  • 1 regional transit authority

More information on these agency types, as well as a list of agencies, is provided below.

Annual Statewide Transit Report

The Washington State Department of Transportation (WSDOT) is required to develop an annual report by December 1 each year, summarizing the status of public transportation systems in the state for the previous calendar year (RCW 35.58.2796).

To assist with the plan’s development, each municipality (defined in RCW 35.58.272) must submit a system report to WSDOT every year by September 1.

To view the most recent statewide report, see the WSDOT Washington State Summary of Public Transportation. The Statewide Transit Agency Overview (chapter 2) also includes a statewide map of the general areas served by transit systems, although the service areas are based on Department of Revenue boundaries and may not represent the exact service areas.

Transit Funding Sources

Transit revenue consists primarily of local sales taxes, passenger fares, and federal and state grants. For local tax revenue, most transit agencies in Washington rely on the transit sales tax under RCW 82.14.045. City or county transit departments may also rely on other funding sources including (but not limited to) transportation benefit districts, commercial parking taxes (RCW 82.80.030), or utility taxes.

The major statutes providing transit taxing and financing authority include the following:

  • RCW 82.14.045 – Transit sales tax up to 0.9%, with higher rates authorized for a few individual agencies
  • Chapter 35.95 RCW – Financing and taxation for public transportation purposes; applies to all “municipalities” including transit agencies (see definitions in RCW 35.95.020).
  • RCW 35.58.2721 – Authority of “municipalities” (defined in RCW 35.58.272) to acquire and operate public transportation and issue debt
  • RCW 81.104.170 – Additional sales tax authority for high-capacity transit service operating principally on exclusive rights-of-way

A few individual transit agencies may have additional statutory authority. Also see our page on Transportation Grants and Loans.

Public Transportation Benefit Areas (PTBAs)

Most transit agencies in Washington are public transportation benefit areas (PTBAs). PTBAs were authorized in 1975 and are governed by chapter 36.57A RCW. Passenger-only ferries were authorized in 2003 pursuant to RCW 36.57A.200 and RCW 36.47A.210.

Below is a list of all PTBAs as of 2020 and their current sales tax rates. The state Office of Financial Management (OFM) releases population estimates for each PTBA every fall pursuant to RCW 36.571.010.

County Transit Authorities

There are a few types of transportation entities operated at the county level.  In addition to the types of entities listed below, counties may also operate passenger-only ferry districts pursuant to RCW 36.54.110 - RCW 36.54.190.

County Public Transportation Authorities

County public transportation authorities (RCW 36.57.010 - 36.57.090) may be formed by any county to provide countywide public transportation services (including all incorporated cities and towns within the county). Below is the list of county public transportation authorities formed under these statutes.

King County Metro Transit 0.9% Serves entire county, including all cities and towns. Initially operated by Municipality of Metropolitan Seattle in 1972, merged with King County in 1992 (retaining powers of chapter 35.58 RCW).

Unincorporated Transportation Benefit Areas

Unincorporated transportation benefit areas (UTBAs) are authorized by RCW 36.57.100 - 36.57.110 and allow counties to perform transit functions in some or all of their unincorporated areas, except areas already included in a PTBA. The UTBA may only include areas that would reasonably benefit from such service.

Currently, MRSC is not aware of any UTBAs in Washington. Garfield County replaced its UTBA with a county public transportation authority in 2016, and Whitman County established a UTBA but took no further action and officially dissolved the UTBA in 2017.

Regional Transit Authorities

Regional transit authorities (RTAs) may be formed by two or more contiguous counties each with a population of 400,000 or more, for the purpose of developing and operating a high capacity transit system. RTAs are governed by chapter 81.112 RCW. Sound Transit is the only RTA, and no other counties are currently eligible.

Agency Funding Notes
Sound Transit Property taxes, sales taxes, motor vehicle excise taxes Provides light rail, commuter rail, and express bus service to King, Pierce, and Snohomish counties.

Six-Year Transit Development Plans

Transit agencies are required to prepare and adopt a six-year transit development plan (RCW 35.58.2795). If the transit agency is located within a city or county that has adopted a comprehensive plan, its six-year transit development plan must be consistent with those comprehensive plans.

The transit agency must review and update its six-year plan every year by September 1. Following adoption, the transit agency must file the plan with the state secretary of transportation and Transportation Improvement Board, as well as the cities, counties, and regional planning councils the transit agency is located within.

For links to each agency’s transit development plan, refer to the Washington State Department of Transportation’s Summary of Public Transportation.
