Potrero Yard Modernization Project - Vibrant and Safe Streets and Sidewalks

Vibrant Communities

The Project will create an environment that welcomes street-level activity through a mix of:

Retail offerings
Flexible multipurpose spaces for street vendors
Public restrooms
Safety enhancements for bicyclists and pedestrians
Updated landscaping
Public visibility of Muni operations
Public art

PNC and the SFMTA have received community suggestions to support this vision of a vibrant space including types of retail, street vendors, plant species, and art media to integrate into the facility. Much of this feedback has been incorporated into the project plans or is under consideration:

Retail offerings that reflect community needs and include community-based retailers or organizations.
Opportunities for street vendor spaces to be used for farmer’s markets, art and craft fairs, and other programmed events.
Public art that reflects the diversity of the surrounding neighborhoods while also integrating into the facility architecture through its materials such as glass or mosaic tiles.
Planting palette that lists prospective plant species including some community favorites such as the Golden Medallion, Strawberry, and Princeton Sentry Ginkgo trees.
Preserving existing trees when possible, particularly along 17th Street.

Input received from the Friends of Franklin Square resulted in the inclusion of a public restroom at 17th and Bryant streets that can be utilized by park users and is across from the children’s playground at Franklin Square.

Improvements for Cyclists and People Walking

The project supports active transportation adjacent to Franklin Square. Enhanced bike lanes and bike parking for residents will create a safe space for cyclists as part of an existing SF Bike Network along 17th Street. This will create a safer and more convenient space for cyclists and encourage bike riding as a form of transportation and recreation. Other proposed cyclist amenities include:

37 bike racks for short term parking along the perimeter of the site and more than 300 stalls of long-term bike parking for both residents and SFMTA employees.
Protected and widened (Class IV) bike lanes on the north and south sides of 17th Street between Bryant and Hampshire streets with new 2-foot concrete barriers, allowing for safer bike movements. Parking would need to be removed on the north side of the block to accommodate these improvements.
Bike lanes are a minimum of five feet wide but typically six feet in most areas. Width varies due to variations in curb width.
The existing bus entrance on 17th Street will be removed to minimize bus interactions with pedestrians and bicyclists.

Proposed pedestrian enhancements are designed to create vibrant sidewalks through:

A mixture of concrete sidewalks and specialty paving
Upgraded curb ramps that meet the American Disability Act (ADA) requirements
Upgraded crossings to support pedestrian safety
Curb bulb-outs to minimize the crossing width for pedestrians crossing the street
Carefully selected and placed outdoor furniture

Landscaping Plan

The landscaping plan has a mix of trees, including:

Seven existing Nichol’s Willow-Leafed Peppermint trees that are along 17th Street
Three tree species identified as the Community favorites during a community survey issued in Spring 2023: Golden Medallion Tree, Strawberry Tree, and the Princeton Sentry Gingko Tree
Other trees that moderate water well or are pollinator species will be included, such as: Ray Hartman Ceanothus tree, Little Gem Magnolia tree, and the Jacaranda

In total 48 trees are planned around the site on the street level.
