Transportation

Biker using the I-90 Trail Crossings at West Mercer Way

The transportation team works to maintain over 75 miles of public roads, extensive pedestrian network, and bicycle facilities to ensure that all modes of transportation work efficiently and safely together. In addition to projects planned in the Transportation Improvement Program (TIP), the team also evaluates requests made by citizens concerning safety and operational improvements related to city streets, public parking lots, sidewalks, bus stops, and more.

Information about future projects can be found in the City’s Transportation Improvement Program (TIP).

Transportation Request Process

Step 1: Submit a Request

Identify the traffic/roadway related concern (such as speeding, pedestrian/bike safety, parking, signing, lighting, etc.) to the City. Please include as much information as possible, including a detailed description of the location and the time of day that the issue occurs. Submit your requests HERE.

Step 2: Evaluation

Transportation/traffic-related requests will be reviewed and analyzed by the transportation engineering team. Staff may conduct a site visit, collect data, or study crash history to help identify the problem, cause, and solution. When determining the appropriate solution and response, the City must consider:

  • Compliance with City/State/Federal guidance and regulation for traffic control and design standards (e.g. stop signs) in relation to roadway characteristics.
  • Relation to past and future projects included in the City's TIP.

Step 3: Response

When a solution has been identified, engineering staff will work with field crews and/or the police department to implement. If the cost of the solution exceeds available maintenance funds, it may be proposed to the City Council in the next six-year Transportation Improvement Program (TIP) proposal.  If requested, City staff will provide a response and updates to the resident.
