Sloat Boulevard Pedestrian Safety Improvements


Winner of the 2016 Caltrans Excellence In Transportation Awards / Transportation System Operations Improvements. read more..  








The California Department of Transportation (Caltrans), working in conjunction with the San Francisco Municipal Transportation Agency (SFMTA) and San Francisco Public Works is planning various pedestrian enhancement projects along the Sloat Boulevard (State Route 35) corridor between 36th Avenue and 21st Avenue.  Public Works pedestrian safety improvements were completed in Summer 2016. 

The following is a summary of milestones associated with the project as well as previously complete projects.

2005 – Caltrans installed vehicle speed feedback signs.
2010 – Supervisor Carmen Chu requested Caltrans develop plans to improve pedestrian safety.
2012 – Caltrans redesigned portions of Sloat Boulevard by reducing the number of lanes, adding bicycle lanes, reducing the speed limit to 35 mph and adding “yield to pedestrian” signing/striping at all intersections with existing marked crosswalks.
2013 – The City of San Francisco secured funding for a project that constructed bulb outs and a HAWK beacon at the Sloat Boulevard/Forest View Drive-Vale Avenue intersection to further increase the safety of pedestrians by creating a controlled pedestrian crossing. The City worked in coordination with Caltrans to develop and deliver the project.
2013 – As part of a regional transportation safety project, a Project Initiation Document (PID) was approved to install HAWK beacons throughout Caltrans District 4 (Bay Area) on various State Routes, including Sloat Boulevard (Route 35).
April 2015 – A Project Initiation Document (PID) was approved for a Pavement Rehabilitation Project on Sloat Boulevard between Skyline Boulevard and 19th Avenue.
August 2015 – In an effort to minimize construction impacts along the corridor, the Sloat Boulevard portion of the regional HAWK beacon project was separated from the original project and was combined with the Sloat Boulevard Pavement Rehabilitation Project.
Spring 2016 – San Francisco Public Works constructed bulb outs at Sloat Boulevard/ Everglade DriveConstanso Way and a HAWK beacon at Sloat Boulevard/23rd Avenue
Summer 2016 – Design for both the Caltrans HAWK beacon project and the Pavement Rehabilitation project was completed.
March 2017 – Construction of the Caltrans HAWK beacon and Pavement Rehabilitation project is scheduled to begin.


Proposals were presented to the communuty at public meetings in the neighborhood on January 13, 2016 and again on February 9, 2016.  Community members were asked to fill out a questionnaire, which were compiled and reviewed.

Based on community feedback and further analysis, the following project modifications are proposed:
  • Shorter red zones. This change maintains approximately three parking spaces previously proposed to be removed.
  • SFMTA is no longer pursuing the bus bulb on 36th Avenue; a smaller pedestrian bulb is proposed to provide sidewalk space for Hybrid Pedestrian Beacon (HAWK) beacon equipment. This change maintains approximately two parking spaces previously proposed to be removed.
During the outreach process, Sloat Boulevard neighbors provided feedback on the proposed project elements.  In an effort to respond to this feedback, the project team has prepared this “Response to community questions, comments and concerns”.  Please note we have reorganized the document to make it easier to read and added additional information. 

Project Elements

Pedestrian crossing
Caltrans is planning to repave Sloat Boulevard between Skyline Boulevard and 19th Avenue in San Francisco.  As part of this repaving project, Caltrans will upgrade intersection curb ramps and pedestrian walkways to be compliant with current Americans with Disabilities Act (ADA) standards.  Furthermore, Caltrans is planning to install five Pedestrian Hybrid Beacons (commonly referred to as “HAWK” beacons) at the following locations:

  • Sloat Boulevard/21st Avenue
  • ​Sloat Boulevard/26th Avenue
  • Sloat Boulevard/El Mirasol Place
  • Sloat Boulevard/Everglade Drive
  • Sloat Boulevard/36th Avenue

These pedestrian beacons would be similar to the one that was recently installed at Sloat Boulevard/Forest View Drive.  Additionally, Public Works completed the installation of another Pedestrian Hybrid Beacon at Sloat Boulevard/23rd Avenue. The new crossing signals are activated by pedestrians with a push of a button, giving drivers a red light for safer crossings.

An alternative design is being considered at the intersection of Sloat Boulevard/El Mirasol Place which would result in full signalization of the intersection.  This would allow for greater flexibility in routing Muni’s No 57 Parkmerced line by allowing the bus to make a U-turn at this location, creating a direct connection to the Lakeshore Plaza Shopping Center.  This element is still under review and the recommended control forthe intersection will be provided in the revised proposals.

To supplement the planned pedestrian improvements along Sloat Boulevard, Caltrans, in coordination with SFMTA, is proposing installation of pedestrian bulb-outs at these four locations:

  • Sloat Boulevard/21st Avenue
  • Sloat Boulevard/26th Avenue
  • Sloat Boulevard/El Mirasol Place
  • ​Sloat Boulevard/36th Avenue (a smaller pedestrian bulb is now proposed)

Bulb-outs are a commonly applied pedestrian tool to enhance pedestrian visibility, shorten the crossing distance and tighten turning radius.  More information on bulb-outs can be found at the following links:

Muni modifications
Two of the pedestrian bulb installations would result in the need to relocate Muni bus zones at Sloat Boulevard/21st Avenue and Sloat Boulevard/26th Avenue.  Additionally, the existing eastbound bus zone at Sloat Boulevard/El Mirasol Place is located between the crosswalks, which is a non-standard bus zone location.  As such, it is proposed that this bus zone be located further west, towards Middlefield Drive.  All of these bus zones serve the Muni ‘s No. 23 Monterey line.
