Treasure Island Phase 1 Parks and Open Space
Waterfront Plaza:
A public plaza, ferry terminal, and associated coastal landscape located on the waterfront opposite historic Building 1. The approximately 400-foot by 100-foot plaza will serve as an intermodal hub connecting multiple modes of transit including cyclists, pedestrians, ferry riders, shuttles, and buses. The Bay Trail is a key component of the waterfront design and extends through the plaza to allow continuous public access.
Building 1 Plaza:
This Plaza provides the context and forecourt for the Historic Building 1, one of the most architecturally significant buildings remaining on Treasure Island. The design for Building 1 Plaza provides a welcoming arrival point to the Island, creating a central civic space and forecourt to the Historic Building 1. The new improvements form an important “urban hub”, linking the Ferry Terminal and Building 1 to the Marina Plaza and the retail street beyond.
Building 2 Plaza:
The landscape surrounding Building 2 is informed by the grand scale and simple form of the historic hangar structure. Each elevation and side of the building has a unique character and relationship with surrounding spaces as well as a distinct shadow pattern created by the mass of the building. The design for the areas surrounding the building honors and recognizes the historic significance of the structure and responds to the unique conditions that define each edge.
Building 3 Plaza:
The space between the Building 2 and 3 is framed by the massive barrel vaults that distinguish the east and west elevations of the historic hangar structures and is differentiated by its large scale. The design concept for the Building 3 open space builds on this history to create a large plaza and event space. On a regular basis the plaza serves as a public parking area serving the nearby retail and marina uses.
Clipper Cove Promenade:
On the south side of Treasure Island, the Clipper Cove Promenade provides access along the marina waterfront and creates a linear open space oriented toward the water and marina activities. The promenade is part of the Bay Trail and will connect on either end to future continuations of the trail system. The promenade ranges in width from 35 to 40 feet and will include a designated cycle track (a protected lane dedicated for bicycles) and a continuous pedestrian promenade.
Cultural Park:
The Cultural Park will be a focal point and civic gathering space for Treasure Island, providing an idyllic setting for the existing Chapel. A spectacular view of the San Francisco skyline, spanning from the Golden Gate to the Bay Bridges, is highlighted for Park users. Upon arriving at the Island, the Cultural Park becomes a focal point at the terminus of the approach causeway. Treasure Island’s Cultural Park will offer flexible open spaces and a place of refuge in its urban context, offering quiet relaxation for both sightseers and Island dwellers alike.
Cityside Waterfront Park:
Situated on the Western edge of Treasure Island with dramatic views of the Bay Bridge, downtown San Francisco and the Golden Gate, the Cityside Park is envisioned as an iconic destination that will draw visitors and residents alike to walk, run, ride and linger along this spectacular waterfront. When complete, the Cityside Waterfront Park will be a 24-acre open space, 300-feet wide from the shore to Cityside Avenue and around three quarters of a mile in length.
Eastside Commons:
The Eastside Commons create a grand, vehicle-free, and socially active pedestrian and bicycle connection from the Eastern Shoreline Park through the Eastside neighborhood to the Island Center and Intermodal Transit Hub. The Commons are approximately one-half mile in length. As the center of the largely residential Eastside District, the Commons serve as a neighborhood park and community space.
Eastside Stormwater Garden:
The stormwater treatment garden is an approximately 4-acre park located at the southern edge of Eastside Park and adjacent to the future Sports Park. This centralized treatment area collects and cleans runoff from the impervious areas of the nearby streets and development parcels. The design of this treatment area is inspired by the patterning of agricultural landscapes and forms a linear patchwork of basins of various size and plant palettes which both clean the stormwater and provide pollinator habitat.
Eastern Shoreline Park:
Situated on the southeastern corner of the island, Eastern Shoreline Park is envisioned as an iconic park on Treasure Island with grand views of the Bay Bridge, Yerba Buena Island and the East Bay. When complete, the Eastern Shoreline Park will be a 9.8 acre open space that wraps the eastern neighborhoods of the island and will include a waterfront promenade and plazas planted with tall trees to shelter the flexible lawn, picnic and other programmed spaces between them. More protected than the western facing Cityside Park, this park provides an opportunity for residents and visitors to enjoy the waterfront and its panoramic views without the direct force of the wind coming from the Golden Gate.
Yerba Buena Island Phase 1 Parks and Open Space
YBI Hilltop Park:
This site is a cultural and ecological arboretum. It tells an evolutionary story with layers of time embedded elements such as stairs, foundations, and ruins as the site flora transitions from a historic ecology to a cultural landscape. Both hilltops act as foci of two distinct experiences within the arboretum. The east retains and reveals the site’s ecological history, while the west hilltop cultivates an attention to the island’s cultural history through remnants and a focus on the built landscape. The park includes vista points at each hilltop which will give visitors a stunning 360 degree view of San Francisco bay.
YBI Beach Park:
Clipper Cove Beach is one of the unique destinations and true wonders on Yerba Buena Island. The Clipper Cove Beach Park is situated on a relatively flat bluff above Clipper Cove beach on the northeast side of Yerba Buena Island. Historic Building 10 was relocated and may include community events, special event rentals, water access services or rentals, and non-profit functions. The park will provide a lawn and picnic space for passive recreation and a new access route between the top of the bluff and Clipper Cove Beach.
YBI Trails:
Yerba Buena Island is a remarkable ecological resource to the San Francisco Bay Area. The proposed network of trails, overlooks, habitat management areas, and open space will add significant ecological and social value to the region. These improvements will also serve to increase public access to Yerba Buena Island, San Francisco’s natural wonder in the Bay.
