Neighborhood Speed Management Program

Neighborhood Speed Management Program

What is the NSMP?

The city's Neighborhood Speed Management Program (NSMP) implements engineering, education and enforcement to slow speeding traffic on residential streets. 

The NSMP accepts applications from community members year-round. Please see more information below on the projects that are being planned and implemented. More information on how to apply and application status can also be found below.

On March 11, 2019, the Transportation Advisory Board (TAB) held a public hearing for residents to speak about speed hump project proposals for locations on the 2018 NSMP Simple Project list. Following the public hearing and a staff presentation, TAB recommended installing speed humps on 37th Street , 55th Street , South 41st Street , South 46th Street , and Grinnell Avenue. Staff plans to install speed humps on the five project streets in September 2019, and will notify residents in advance of construction.

Following a February 2019 recommendation from TAB to proceed with the top two projects on the  NSMP Complex Project list pdf , staff began planning the 26th Street (between Kalmia Avenue and Jay Road) and 55th Street (between Baseline Road and Sioux Drive) projects in May 2019. 

September 18 and 19: Final Neighborhood Meetings

At the first and second meetings we discussed existing conditions and evaluated two design alternatives for each street. Please attend the third and final neighborhood meetings to review the staff recommended designs for 55th Street and 26th Street and share your thoughts with city staff and consultants. The meetings will be open house-style so you can attend whenever in the evening is best for you.

Northern Boundary Extended for the 26th Street Project 

After receiving feedback from the first neighborhood meeting and an application from residents on 26th Street between Norwood Avenue and Jay Road, the 26th Street NSMP Project boundaries have been extended and will now address speeding on 26th Street between Jay Road and Kalmia Avenue.

City staff accepts NSMP applications year-round and evaluates them on an annual basis. The next deadline for application evaluation will be in late spring 2020. Please use the links on the upper right-hand corner of the page to access the online application and neighborhood petition.

Here are a few key pointers:

  • Only residential and collector streets are eligible for participation in the program.   Eligible streets are in black and blue on the City of Boulder Street Classifications pdf map.

  • All applications requesting engineering treatments (such as speed humps and traffic circles) must include a neighborhood petition pdf with signatures from 20 neighbors or 30 percent of households on the same block, whichever is less.

  • Staff will review and rank applications requesting engineering treatments based on the criteria laid out in the NSMP final guidelines pdf. All applicants will be notified of the ranking. Staff will then present a list of prioritized projects to the Transportation Advisory Board (TAB) for review.

  • Projects with engineering treatments will be categorized as "simple" or "complex."

    • Simple projects are those that are expected to have a localized impact on reducing speeds, address speeding issues on a short segment of a non-critical emergency response route and have little effect on traffic diversion. They are also anticipated to cost less than or around $10,000. Simple projects will be implemented by staff after a recommendation by the Transportation Advisory Board.

    • Complex projects may include impacts to neighboring streets or other travel modes, be located on a designated critical emergency response route and cost more than $15,000. Complex projects must receive a recommendation to proceed from the Transportation Advisory Board and must also be approved by City Council.

  • All applicants are eligible to receive educational materials and enforcement in their neighborhood.

You can  read the final guidelines   pdf and review public feedback pdf about the guidelines from the June TAB meeting. You can also view higher resolution versions of the Critical Emergency Response Routes pdf (Attachment A) and City of Boulder Street Classifications pdf map (Attachment B).

  • If you submitted an application  between April 27, 2018, and May 31, 2019, staff is currently evaluating your application. Applications that qualify for engineering will be prioritized by TAB at the October and December 2019 meetings.

  • Applications submitted after May 31, 2019, will be evaluated beginning in May 2020.

Staff emails regular updates to all applicants with updates on the program and what to expect in the coming months. If you have not been receiving updates, please

Twelve projects were considered for implementation in 2018. To view the projects and how they were selected for consideration, see the neighborhood forum meeting materials pdf.

Staff held two neighborhood forums on May 24 and May 29, 2018, for residents to discuss 12 simple project pdf proposals with staff. Staff also presented traffic calming concepts and neighborhood feedback to TAB at a public hearing on June 11, 2018.

Based on neighborhood feedback, TAB made a recommendation to move forward with 11 projects and asked for a new petition for the project proposed for Augusta Drive. Additionally, the speed hump on Edinboro Drive has been postponed based on neighborhood feedback. The 2018 NSMP project map pdf shows the 10 project locations.
