Transportation Impact Fees

Update:  Transportation Impact Fee Rate Schedule - As of 1-1-18

Impact Fees
On October 1, 2015, the City of Bainbridge Island initiated a Transportation Impact Fee Program.  All projects are required to pay a Transportation Impact Fee (TIF)
per Bainbridge Island Municipal Code (BIMC) 15.30.
TIFs are used by the City for pay for transportation projects. The fee amount varies depending on the land use or combination of uses. For example, residential fees and commercial fees are not the same because they generate different amounts of traffic.

Does Your Project Trigger TIFs?
There are many types of projects which do not trigger TIFs, generally projects which do not generate new PM peak hour trips. To determine if your project will require TIF payment, please review the Transportation Impact Fee Triggers handout.

Estimate Your Fee
See the Transportation Impact Fee Rate Schedule above and use the Transportation Impact Fee Calculation Worksheet to estimate any applicable fee. It is recommended that the worksheet be prepared by a Washington State licensed professional engineer who is qualified to perform traffic studies. 

TIF Submittal
TIFs are due prior to the issuance of a building permit and the amount is based on the fee schedule in effect at the time a complete building permit application is filed. Transportation Impact Fee Process
Transportation Impact Fee Application
Submit the TIF Application form with all building permits where TIF may be applicable.
Transportation Impact Fee Independent Calculation (Optional)
The applicant may choose not to pay the TIF according to the current TIF schedule/rates by submitting the Transportation Impact Fee Independent Fee Calculation Form and associated fee for review. The documentation submitted must be prepared by a Washington State licensed professional engineer that is qualified to prepare traffic studies.

Transportation Impact Fee Deferral
Pursuant to Revised Code of Washington (RCW 82.02.050(3) and BIMC 15.30.210, a developer/applicant, for a single family residential unit, may request that payment of impact fees be deferred until final inspection of the applicable building permit. See Impact Fee Deferral Form.  
Transportation Impact Fee Claim for Credit (Optional)
If an applicant dedicates land and/or constructs road improvements that are identified in the Current TIF system improvement projects as part of a development activity, they can be issued a credit using the Transportation Impact Fee Claim for Credit Form.  Refer to the latest Traffic Impact Study for the list of system improvement projects.
After City staff receives the Transportation Impact Fee Calculation Spreadsheet and either of the optional forms, they will process the information and provide the application with the final TIF amount in writing. TIF payment is due prior to the issuance of a building permit.
