Traffic Impact Analysis
Traffic Impact Analysis (TIA)
- A TIA may be required if you are changing the building or space use from a non- restaurant or food/beverage use and increasing trips to and from your site.
- A TIA must be prepared by a licensed Traffic Engineer.
- If your proposed use will result in additional traffic to and from your establishment, this could result in the need to pay a Transportation Development Tax (TDT). TDT fee schedules are set by Washington County, but collected by the City of Tualatin. In addition, the Traffic Engineer will be able to evaluate if any improvements are needed to the site you have selected for your business. These may include:
- On-site parking and circulation changes
- Potential off-site access
- Vision clearance
- Safety
- Improvements to adjacent public streets or facilities
Please call the Development Engineering Associate with any engineering questions at 503.691.3035.
