Traffic Calming

The Traffic Calming Program was developed through the guidance of the City’s Transportation Committee to create a safer roadway environment for all users, enhancing neighborhood livability, and engaging the community to become an active part of resolving localized traffic issues. The Program serves as the standard operating procedure for staff to address traffic safety issues that are requested by residents.  Click on this link to find the adopted  Traffic Calming Program document.

There are a number of tools that have been identified to address specific traffic conditions occurring in your neighborhood.  These tools are categorized into two areas:


Educating the community on transportation issues is an important first step in addressing traffic concerns in neighborhoods.  One of the most frequent comments made to the Public Works Department is the need to address speeding along residential streets.  Our studies show that the majority of speeders on neighborhood streets in Mukilteo are local residents.  By educating the community and encouraging safe driving, we can begin to change driver behavior and reduce vehicle speeds.  Enforcement, such as police citations, can also help to alleviate speeding concerns.

What kinds of options or tools are available to my neighborhood under this category?

  • Neighborhood speed watch program
  • Neighborhood traffic safety newsletters
  • Radar trailer/dolly
  • Heighten school zone enforcement


Physically changing how the road looks – whether with signing, curbing, or other traffic calming measures – works to alter the behavior of motorists, pedestrians, and bicyclists.  These tools help to manage traffic volumes, reduce vehicle speeds, and improve sight distance.  Engaging the community in developing the Traffic Action Plan and garnering support are key elements to the success of any project that modifies the streetscape.

What kinds of options or tools are available to my neighborhood under this category?

  • Chicanes/slow points
  • Brush trimming
  • Curb extensions
  • Lane striping
  • Medians
  • Raised crosswalks
  • Neighborhood entrance signs
  • Speed humps
  • Speed dots
  • Stationary radar sign

  1. Submit a Traffic Calming Request for Action Form (click here to fill out the form) describing your concerns in as much detail as possible, including if there is a specific time of day or day of the week you notice the problem to be at its worst.  The more information we have as we assess the situation, the better prepared we are to address your concern.
  2. Staff visits the location and reviews traffic conditions.  Speed and volume counts may be conducted and/or staff will review previous traffic studies or reported accidents.
  3. A Traffic Action Plan is developed.  This plan is specifically tailored to your concern based on the findings in Step 2 and other citizen observations.  The plan includes a list of tools selected from those available under the Traffic Calming Program which are best suited to address your concerns.
  4. Together, citizens work with staff on implementing the Traffic Action Plan.  This is your opportunity to become an active partner in helping to solve your neighborhood traffic concerns.
  5. The effectiveness of the plan is evaluated through additional follow-up studies and citizen input, if needed.
