SITE BACKGROUND

Tunnel Top Park is a local grassroots initiative of residents in the Potrero-Dogpatch Neighborhood. Early fundraising, design, and implementation has been led by the Tunnel Top Park Steering Committee with fiscal sponsorship of the San Francisco Parks Alliance.

The site is situated at the intersection of Pennsylvania and 25th Streets above the southern portal of the Caltrain tunnel. The site slopes steeply to the north where it is bounded by 25th Street. To the west, a large serpentine outcropping rises towards the crest of Potrero Hill. The eastern edge of the site is bounded by Pennsylvania Street, while the southern end of the site opens onto spectacular vistas towards the Portola and Bayview neighborhoods.

For many years, this remnant piece of land was treated as an informal dumping ground. In July of 2014, the Tunnel Top Steering Committee formed to spearhead transformation of the site into a community-serving open space. The project, under the Fiscal Sponsorship of the San Francisco Parks Alliance, entered into a lease agreement with Caltrain for use of the site in 2015; and volunteer removal of the garbage and debris began that same year. The Steering committee pursued and was awarded its first funds by the San Francisco Community Challenge Grant Program in December 2014. This first grant funded conceptual site planning by Groundworks Office, as well as ‘Phase 1’ projects such as paving of paths, an overlook, and a large gathering space or ‘plaza.’ ‘Phase 1’ site improvements were implemented by CATMEX and supplemented by volunteer community workdays throughout 2015 and 2016. In November of 2015 Tunnel Top Park was the recipient of a San Francisco Carbon Fund Grant which resulted in the initial planting of over 450 plants and trees.

PAVEMENT TO PARKS PARTNERSHIP with CALIFORNIA COLLEGE OF THE ARTS

In the Fall of 2015, architect and faculty member at the California College of the Arts, Antje Steinmuller, and San Francisco Pavement to Parks Project Manager, Robin Abad, initiated a collaboration between the two organizations with the goal of contributing to open space projects in Dogpatch-Potrero through the Central Waterfront-Dogpatch Public Realm Plan. The collaboration has manifest in research and site-specific design projects. See below for details on the different phases of the ongoing collaboration.

Design-Build Studio, Summer 2016
Pavement to Parks Professional Practice Interns Fernanda Bernardes and Anh Vo, under the supervision of Meghan Dorrian (CCA) and Robin Abad (SF Pavement to Parks), led the design refinement and implementation of ‘interim amenities’ at Tunnel Top Park in the Summer of 2016. The concept design, ‘Undulating Landscape’ was selected by a Jury comprised of Tunnel Top Park community members and CCA faculty from several generated during the Spring 2016 Building Technology Seminar. During the late Spring and early Summer 2016, the Tunnel Top Park Steering Committee met routinely with the CCA / Planning Department team to refine a site-wide plan and design for ‘Undulating Landscape,’ a modular prototype that incorporates seating, fencing, and lighting for deployment across the park. The summer 2016 design-build studio fabricated and installed “Undulating Landscape” at the Park in August 2016.

Building Technology Seminar, Spring 2016

Building Technology Seminar, Spring 2016
Continuing after the CCA Active Urbanism Seminar in the Fall of 2015, Meghan Dorrian (CCA) and Robin Abad (SF Pavement to Parks) collaborated on a Building Technology Seminar in the Spring of 2016 focusing on Tunnel Top Park. With guidance from the Tunnel Top Park Steering Committee, the students explored different concepts for multi-functional, modular prototypes emphasizing innovative use of concrete and timber. The Steering Committee outlined programmatic and performance requirements such as seating, shading, nighttime lighting, and fencing. The seminar culminated in an onsite presentation of prototype concepts constructed at full-scale. A Jury comprised of Tunnel Top Park community members and CCA faculty critiqued and selected the winning concept by students Fernanda Bernardes, Anh Vo, and Joshua Olivas.

Active Urbanism Seminar, Fall 2015

Active Urbanism Seminar, Fall 2015
In the Fall of 2015, Antje Steinmuller (CCA) initiated a collaboration with Robin Abad (SF Pavement to Parks) on a graduate research seminar. The ‘Active Urbanism’ seminar investigated the sharing economy and its ramifications on the production of public open space. During the first half of the semester, students identified and researched local ‘sharing economies’ of food, textile manufacturing, media production, housing, transportation, and public-private open spaces.

The second half of the semester focused on the Dogpatch in San Francisco, a neighborhood with a high proportion of architecture and design professionals, vast postindustrial landscapes, and numerous grassroots open-space initiatives being implemented in the face of rapid influx of new residents and workers to the area. The seminar resulted in several speculative proposals for open spaces in Dogpatch, all incorporating some aspect of a local ‘sharing economies.
