Transportation Impact Fees

In July 2014, the City Council adopted Shoreline’s first Transportation Impact Fees (TIFs). TIFs are charged during the building permitting process and used to fund projects to maintain or improve levels of service on Shoreline's streets. The intent is to share the financial responsibility of providing transportation facilities, such as roads and intersections, that support future growth with the development that grows our population and economy.

All projects that add trips to City streets are required to pay the impact fee. This includes accessory dwelling units (ADUs) or Mother in Law apartments or any project that creates space for extra 'trip' generating residents or uses on your property. The fee is proportionate to the size of the development, or change in use. More potential residents, customers, or visitors = higher fees, as identified in the Impact Fee Table.

The Growth Management Act, a Washington state Law, requires cities to plan and provide transportation facilities to accommodate growth. By charging impact fees, cities can ensure the required transportation facilities are constructed to meet the demands of future growth and new development. TIFs are allowed by state law and many cities in the region have already adopted them. TIFs can only be used for traffic capacity projects. They cannot be used for other transportation needs, such as street maintenance or sidewalks.

The City has identified locations where new trips from development are projected to increase existing congestion on Shoreline streets (such as N 175th Street and Meridian Avenue N), or will result in newly congested areas. Funds generated by TIFs will be used to fix these areas and maintain adopted levels of service on Shoreline's streets. 

Shoreline’s Transportation Impact Fees went into effect January 1, 2015.
