Neighborhood Slow Streets

Boston's approach to traffic calming on residential streets.

We aim to reduce the number and severity of crashes on residential streets. We also want to lessen the impacts of through traffic, and add to the quality of life in our neighborhoods.

Each year, neighborhood associations, community groups, faith-based institutions, or other organized groups of neighbors will be able to apply for traffic calming in a specific neighborhood. Selected neighborhoods will work with the Transportation Department and Public Works. We'll review the area, identify opportunities, and put in place changes to slow traffic speeds and improve safety.

About the program

Instead of planning and putting in place changes on one street at a time, Boston will address an entire “zone” within a neighborhood.

We will look at every street within the zone to find problems and design solutions. We'll do this while working with the community. We anticipate traffic-calming elements and safety improvements will be proposed for almost every street within the zone.

When each zone’s plan is put in place, streets will have visual and physical cues to slow drivers to 20 mph. This will make each street feel more inviting for people of all ages who are walking, playing, or bicycling. The Slow Streets program will emphasize quick-install, low-cost fixes, such as:

  • signage and pavement markings
  • speed humps, and
  • daylighting.


The Neighborhood Slow Streets program will follow the general process below. We've identified roles for City departments and for community applicants and partners. Once a neighborhood is picked for the program, residents should expect the process to take about two years.

Application →

  1. City announces application period and encourages broad participation in program.
  2. Applicant builds support among residents and greater community.
  3. Applicant solicits letters of support from key stakeholders. This includes neighborhood associations, police precincts, schools, Neighborhood Liaisons, and elected officials.
  4. City reviews and evaluates zones based on objective criteria.
  5. City notifies applicants and officially announces participating neighborhoods.

Plan development →

  1. Community partner hosts a neighborhood walk with City staff, key stakeholders, and residents.
  2. Community partner may help with a qualitative survey of neighborhood residents.
  3. City collects and compiles relevant data. This includes crash history, existing neighborhood plans, and speed studies.
  4. City hosts initial public meeting to present data and a recommended plan for community feedback.
  5. City completes preliminary engineering work.
  6. City hosts a second public meeting to present final traffic calming plan. Community members will have the opportunity to provide additional comments.


  1. City works with contractor to develop construction schedule, which is shared with the community partner and general public.
  2. Construction takes place during weekday waking hours, whenever possible.
  3. Community partner, in collaboration with the City, may conduct post-construction qualitative survey.
  4. City collects post-construction data, including crashes and average speeds.

The application 2018 period is now over.

We received 37 applications from across the City and accepted five new communities to join the program. You can read more about our 2018 evaluation process and download our 2018 methodology (pdf, 9.41 mb).

We will accept new application in 2019. We've left the 2018 application materials up for your review.

2018 zones and evaluation

These five zones were selected through an objective evaluation process. We based this process on the pre-established criteria described on our web page and in application materials.

Common questions

Common questions

Neighborhood Slow Streets is a City initiative to slow traffic speeds and improve safety on residential streets within a specific area. When a neighborhood is part of the program, the speed limit on its residential streets will be 20 mph.

Work with your neighbors to submit an application. Applications are due August 24, 2018.

No. Applications must be from a group of residents. This includes:

  • neighborhood associations
  • community groups
  • faith-based intuitions, and
  • other organized groups of neighbors.

We expect demand for the program will outpace the resources available each year. With an application process, we can objectively evaluate interested neighborhoods. 

The application is available in the "Apply" section of this page. If you need a paper copy mailed to you, request it by emailing or call 617-635-1347.

You can email or call 617-635-1347. If you are leaving a voicemail, be sure to leave your name and callback number.

The Neighborhood Slow Streets program prioritizes areas with the most need. We will use objective evaluation criteria to select three to five communities that:

  • are home to higher percentages of youth, older adults, and people with disabilities
  • experience higher numbers of traffic crashes per mile that result in an EMS response
  • include, or border, community places like public libraries, community centers, schools, and parks
  • support existing and planned opportunities for walking, bicycling, and access to transit, and
  • are feasible for the City of Boston to put in place improvements.

We expect to select three to five communities to join the program in 2018.

You are welcome to apply again next year. We expect to accept applications each year.

You must collect at least two full pages of signatures (24 signatures) from people who live in the zone. This helps show a baseline of community support. But, we will not factor the total number of signatures into your score.

While your proposed area could include streets that are not owned by the City of Boston, we likely cannot make changes to those streets.

You can expect to see new signs, pavement markings, speed humps, and improvements to visibility at intersections. In some places, you could see additional changes. These include raised crosswalks, curb extensions, and neighborhood traffic circles.

Stop signs are used to control how traffic flows through an intersection. An engineering analysis must be conducted before a stop sign is installed. Among other things, engineers evaluate how many people drive, bike, and walk through an intersection. They also review the number and type of crashes that have happened.

Stop signs are not traffic-calming measures, but may be considered as part of the Neighborhood Slow Streets program if an intersection meets engineering standards. If you believe an intersection needs a stop sign, make the request through Boston 311.

No. Our snow plowing teams will be notified of locations with speed humps so drivers can know to expect them. Signs will be installed on streets to notify drivers of the location of speed humps.

2017 zones and evaluation

Five communities joined the Neighborhood Slow Streets Program in 2017:

These five zones were selected through an objective evaluation process. We based this process on the pre-established criteria described on our web page and in application materials.
