Mill Creek Raises Traffic Mitigation Fee

Mill Creek Raises Traffic Mitigation Fee to Address Impact on Transportation System
Posted on 11/07/2018
At its meeting on Nov. 6, the Mill Creek City Council unanimously approved raising the City’s traffic mitigation fee by 30 percent to bolster funds for system-wide traffic improvements.

The underlying philosophy of traffic mitigation fees is that new development must pay a proportionate share of the impacts associated with the additional traffic on the road network to maintain an adopted level of service. A fee is assessed to developers based on the number of afternoon peak hour trips.

Available Puget Sound Regional Council travel demand modeling indicates that, on average, 36.5 percent of vehicular trips in Mill Creek are local trips with a trip end within the City.

The previous rate, last updated in 2011, was $3,000 per trip. The Council’s action sets the fee at $3,900 per trip effective Nov. 16, 2018.

The adopted 2019-2024 Transportation Improvement Plan includes eight projects that are necessary as a result of vehicular trip growth, and thus are eligible for traffic mitigation funding with a total estimated cost of $39.9 million.
