INITIATIVES
Our upcoming focus is on facilitating the neighborhood input process to inform the Duboce Triangle Slow Streets Study. The special neighborhood meeting will take place on Monday, November 17, 2025 at CPMC's Gazebo Room @ 45 Castro Street, from 6:00pm to 8:00pm. We will also engage neighbors via email and do special outreach to businesses and members of our community who cannot attend meetings.
Here are the details of the Duboce Triangle Street Study as presented to the public by the Transportation Authority’s Neighborhood Program (NTIP):

Project Description
The existing Noe Slow Street is not meeting the SFMTA Board-set volume target of 1,000 vehicles per day. When the SFMTA introduced the idea of a traffic diverter on Noe Street and 15th Street to reduce vehicle volumes, Duboce Triangle residents requested that before introducing any traffic diversion elements, the SFMTA look at potential impacts to traffic within the neighborhood. This study builds on that request and the need for a safe and comfortable north-south bikeway connection across the Duboce Triangle.
The Duboce Triangle Slow Streets Study will examine opportunities for a more robust and connected north-south Slow Street connection through the Duboce Triangle neighborhood and corresponding changes to traffic circulation. The study will explore the feasibility of converting two existing Class III shared lane bikeways into Slow Streets, possibly replacing or adding to the existing Noe Slow Street: 1) Sanchez Street between Market Street and Duboce Avenue and 2) Steiner Street between Duboce Avenue and Waller Street. These two bikeways would form a key north-south connection in the citywide active-transportation network (see the project area map on the last page). The feasibility of allowing eastbound left turns from Market Street onto Castro Street and prohibiting eastbound left turns onto Noe and/or Sanchez streets will also be explored to maintain traffic without a neighborhood destination on arterial and collector streets from neighborhood streets that can better manage higher volumes of vehicle traffic.
Background
This project originated from efforts to reduce vehicle volumes on the Noe Slow Street in the Duboce Triangle. In early 2023, the SFMTA began developing concepts to reduce vehicle volumes on the Noe Slow Street to meet the SFMTA Board-set volume target of 1,000 vehicles per day on Slow Streets. Three traffic diverter alternatives proposed for the Noe Street and 15th Street intersection were reviewed with neighbors and businesses along the corridor. A consensus could not be reached among project stakeholders regarding the implementation of a diverter at this intersection, and the project was put on hold. A key concern among stakeholders was the potential for traffic diversion onto side streets, and a desire was expressed for a more holistic review of traffic circulation before the implementation of traffic diversion.
Simultaneously, staff has heard a desire from a group of community members for improvements to “the Wiggle” bike route, specifically the southeastern-most blocks on Steiner Street between Duboce Avenue and Waller Street, as well as safety and operational concerns at the Duboce/Sanchez/Steiner intersection, including the possibility of implementing Slow Streets treatments north of Duboce Avenue to reduce vehicle volumes and speeds.
This study will also consider the feasibility of new Slow Streets through the Duboce Triangle neighborhood in the context of the forthcoming San Francisco Biking and Rolling Plan.
Task descriptions
The proposed scope of work for this study includes:
Task 1. Project Management – This task includes biweekly project team meetings, interagency (e.g., Fire Department) meetings, project administration, and reporting.
Task 2. Traffic and circulation analysis – This task includes:
- A study of changes in traffic patterns in the Duboce Triangle neighborhood with Sanchez Street between Market Street and Duboce Avenue and Steiner Street between Duboce Avenue and Waller Street converted into Slow Streets with traffic diversion elements; and,
- An analysis of the feasibility of allowing eastbound left turns from Market Street onto Castro Street and the identification of infrastructure needed (e.g., new signal hardware) if this movement is feasible; and,
- An analysis of the feasibility of eliminating eastbound left turns from Market Street onto Noe and Sanchez streets; and,
- An analysis of the feasibility of traffic calming or diversion elements on Noe Street and circulation changes at the Noe St/16th St/Market St intersection; and,
- An analysis of potential safety impacts, including pedestrian safety, from diverted traffic volumes and turning movements; and,
- An analysis of potential impacts on Muni service from diverter traffic volumes.
-
Task 3. Outreach – This task includes stakeholder and broader community outreach to understand public interests and circulation needs and to hear feedback on proposed circulation changes and conceptual plans for new Slow Streets in the Duboce Triangle neighborhood. Outreach activities could include:
- Direct stakeholder and neighborhood group meetings
- Door-to-door outreach to area businesses
- Pop-up tabling events
- An online survey
- An open house
Task 4. Final study and conceptual plans – The final task includes the development of a report documenting the feasibility of new north-south Slow Streets and corresponding circulation changes, as well as how these changes will work in tandem with one another. The report will identify opportunities and tradeoffs for alternatives and, for those deemed feasible, include conceptual plans for new north-south Slow Streets and corresponding changes, such as circulation changes at the Castro and Market intersection and recommendations for the Noe Slow Street. The final study will include recommendations for implementation next steps.
