Design Guidelines for Street Seats 2013 Program

Guidelines for Street Seats:

Site locations and platform design are approved by the City Traffic Engineer based on the following criteria:

  • The Street Seat platform will sit on top of the existing street surface.  The design should not include any bolts/anchors or other elements that require disturbing the street surface or sidewalk.  
  • The use of high quality, durable materials capable of withstanding year‐round use is required.
  • Facility may not extend beyond six (6) feet from the curb line where there is parallel parking. Angled or perpendicular parking locations will be approved on a case by case basis.
  • The platform design must include vegetation in the form of planters. Plant selection shall be submitted to PBOT for approval. Proper drainage of planters shall be provided.
  • The proposed site should be located on a street with a speed limit of 25 MPH or less. Locations on streets with higher speeds will be considered on a case by case basis.
  • The proposed site should be located at least one parking spot in from a corner or a protected bollard, sidewalk bulb‐out, or other similar feature must be present if located at the corner.
  • The maximum length of the platform must not be longer than the frontage of permit holder’s establishment unless given permission by adjacent property owners.
  • Design must maintain an six‐foot pedestrian zone next to the platform where sidewalk width allows.
  • Platform is not on a street where parking lanes become tow away zones during morning or afternoon hours.
  • The street must not have a grade greater than 5 percent.
  • Site must not be in front of a fire hydrant, active bus zone, active driveway, or over a manhole or public utility valve or cover.
  • Platform must be designed to allow for curbline stormwater drainage.
  • Platform should be as level as possible and flush with the sidewalk height. At least 12 feet of the platform must be flush with the adjacent sidewalk for wheelchair access. Proposed platform furniture must be able to accommodate wheelchair patrons.
  • Platform design must include a physical barrier along the street while maintaining clear visual sightlines to the street. Vertical elements, such as planters and umbrellas, should be included so that the facility is visible to vehicles.
  • The platform shall not be permanent. It should be removable in case street maintenance or other similar needs arise.
  • To protect the platform from parking maneuvers, planters or weighted bollard on either end of the platform are required.
  • 2 feet on either end of the facility will need to be reserved for wheel stops with embedded reflective candlesticks. These will be installed by PBOT after final facility construction/installation is complete. Additional traffic safety items may be added to the final design by PBOT staff.
  • The proposed number of table and chairs shall be approved by PBOT.
