Frequently Asked Questions

The NTCP is a structured program designed to help the City and residents work together to reduce speeding and improve traffic safety in neighborhoods. It provides a range of solutions—categorized by complexity and cost—to address concerns like speeding, cut-through traffic, and pedestrian safety.

Start by completing the Traffic Hazard Reporting Form. Describe the issue, location, and include contact information from others affected. Submit it online or submit hard copy forms to the Public Works Department by email or drop it off at City Hall.

The Traffic Safety Committee will review your submission, and utilizing the Neighborhood Traffic Calming Plan, make a recommendation and determine whether the concern qualifies for Tier I (simple/low-cost), Tier II (moderate), or Tier III (complex) solutions. Staff may conduct additional studies and community outreach before identifying appropriate measures. Tier II and Tier III measures require additional engineering support, recommendations for these measures will be subject to additional meetings and review with the City’s Traffic Engineer and Public Safety Teams.

Solutions range from low-cost signage and striping to more involved improvements like speed feedback signs, curb extensions, or raised crosswalks. A full list is included in the Traffic Calming Program Guide (PDF). 

In most cases, the City funds traffic calming measures. However, the form does ask whether the neighborhood is willing to contribute. Voluntary contributions may help speed up implementation or support demonstration projects. 

The City uses a scoring system based on criteria like speeding severity, crash history, proximity to schools, and pedestrian activity. This helps allocate limited resources to areas with the greatest need and impact. 

Yes. In some cases, the City may pilot temporary treatments such as pop-up traffic circles or speed bumps to evaluate effectiveness before making a long-term investment.
