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.


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.
