List of Transportation Benefit Districts

This page lists and maps all transportation benefit districts (TBDs) in Washington State that MRSC is currently aware of, along with their establishment dates, funding mechanisms, and whether their powers have been assumed.

For more information about TBDs, including their governance and potential revenue sources, see our Transportation Benefit Districts page.

Initiative 976: I-976 has passed, which will eliminate the ability of TBDs to impose any car tab fees if it is upheld in court. An injunction has been filed and upheld by the state Supreme Court while several jurisdictions challenge the initiative's constitutionality. Until such time as the courts render a final decision, revenues will continue to be collected. For more information, see our blog post Changing Forecasts for Transportation Revenues and Other Impacts of I-976. We will provide further updates as they become available.

For additional information on the impacts of I-976, see the Association of Washington Cities (AWC) resources and the state Office of Financial Management (OFM) fiscal impact statement.


Map of Transportation Benefit Districts

The interactive map below shows all TBDs that MRSC is currently aware of. You can filter the map by funding source, county, and whether the TBD's powers have been assumed under chapter 36.74 RCW. For more detailed information about an individual TBD, hover over it or see the list below.

While MRSC attempts to keep this information up-to-date, we cannot guarantee its accuracy. For questions or comments regarding this map or any information on this page, please email Steve Hawley.

Please note: We are currently experiencing technical issues with the map, so not all jurisdictions that have established TBDs are displayed. For the most up-to-date information, please refer to the Excel spreadsheet at the bottom of this page.


List of TBDs

As of December 2018, MRSC is aware of over 100 cities and towns that have formed TBDs, of which about 75% have assumed the TBD's rights, powers, functions, and obligations under chapter 36.74 RCW.

MRSC is only aware of five counties that have established a TBD. One of those (a partial-county TBD serving the Point Roberts peninsula) relies on the border area fuel tax, while the rest are unfunded.
