street shapes the overall concept for the space. A generous, open plaza area unfolds from the rear doors of Building 1, reinforcing the central spine that begins at the Ferry Terminal and leads through Building 1 and Marina Plaza to the retail street. Clusters of Monterey Cypress and plaza-scale trees frame and define this pass-through space, while broad stairs and ramps draw pedestrians through the plaza to the lower elevation of the retail street.

A second spine runs through the plaza in the north-south direction, anchored on either end by garden spaces that subtly negotiate the grade change from the street and draw visitors into the plaza while connecting them to surrounding island destinations. On the southern end of the plaza, a large amphitheater space with terraced lawn seating allows for expansive views out to Clipper Cove and Yerba Buena Island and provides an area for larger gatherings and performances. To the north, a terraced garden echoes the formal geometries of the amphitheater while providing a more intimate, immersive landscape that enables visitors to meander within tiers of richly textured plantings and canopy trees. A series of ramps and stairs flank the gardens, allowing easy access from the sidewalk to the main plaza space.

ACTIVITIES AND PROGRAM

Marina Plaza creates opportunities for a variety of activities. The plaza spaces to the north and south of the central spine are characterized by flexible areas, including groupings of movable café tables as well as a sunken terrace lined with crushed stone paving that allows for informal seating and offers opportunities for individuals or groups to enjoy views out to Clipper Cove and Yerba Buena Island.

The amphitheater provides a large, sunny area for outdoor seating and flexible recreation that can accommodate informal gatherings of different sizes as well as large groups for outdoor performances.

BACKGROUND

The design for Marina Plaza will transform an under-used parking lot and landscape buffer zone into a hub of activity and connectivity for the new island development. Located on the eastern side of Building 1, the existing site encompasses seven feet of grade change and is dominated by a large expanse of blank façade on the back of Building 1. This building casts the northern portion of the site in afternoon shade and can funnel the island’s prevailing westerly winds through the plaza space. At the same time, the site boasts a sunny southern exposure and sweeping views of Yerba Buena Island, Clipper Cove, and the San Francisco skyline, and the substantial grade change presents opportunities to elevate and enhance these views.

DESIGN CONCEPT

Envisioned as a key part of the overall Treasure Island development, Marina Plaza will provide a strong point of connection to the island’s new retail corridor along with other island destinations. The plaza will also provide opportunities for gathering, recreation and entertainment.

The importance of Marina Plaza as the primary link to the retail

4.2.5 MARINA PLAZAThe terraced garden, in contrast, offers a more intimate destination for small gatherings and individual contemplation.

Along the curved façade of Building 1, raised café seating extends the building program into the landscape and provides elevated views over the plaza. In a similar way, a patio with broad steps and café seating wraps around the southern corner of the site adjacent to the amphitheater, providing another desirable area for outdoor dining with southern exposure and expansive views of Clipper Cove.

ACCESS AND CIRCULATION

Most pedestrian traffic will flow through Marina Plaza along the central circulation spine – with visitors coming from the Ferry Terminal and Building 1 Plaza arriving at Marina Plaza through the rear doors of Building 1, and those coming to the plaza from the retail street arriving via the crosswalk at Avenue C. Marina Plaza will be accessible on all four sides, with ADA-compliant ramps connecting the plaza to the sidewalk at the north, south, and east edges of the site, and extending down from either side of the Building 1 doors to the main plaza space.

STORMWATER TREATMENT

The new plaza design includes two areas for landscape-based stormwater treatment. The terraced garden at the north end of the plaza and the stormwater garden at Building 1 Plaza will accept runoff from the plaza as well as from Building 1 and the two new building parcels on the site. Planted with hardy wetland species, these areas will filter pollutants, slow the flow of runoff, and uptake excess water from the site’s paved and impervious surfaces.

street to the Marina Plaza and Building 1. The crushed stone plaza is divided by a large central entry path and surrounded by simple Mediterranean plantings that create a buffer along the front of the building and surrounding streets. Bike share and parking areas are located on both sides of the entry. The area at the southern edge of the space adjacent to Clipper Cove Avenue may be developed with a small building to provide space for Tidelands Trust compliant uses.

The North GardensDirectly adjacent to California Avenue the north gardens will provide a simple backdrop to the large north elevation of the building. This elevation is characterized by shady mornings and late afternoon sun. The gardens will provide a buffer between the street and building and include small seating areas along with a small plaza located in the center of the space.

The East PlazaThe east plaza abuts the large space between Building 2 and 3 and is an open and flexible plaza space supporting interior building functions and larger markets in the adjacent parking area. It is expected that the program and design of the space will evolve and may be further developed by future Building 2 tenants, consistent with the Design for Development and under TIDA’s guidance.

The South AlleyThe south elevation of the building has a low one story historic space that represents a unique opportunity to create a pedestrian scaled retail experience in a sunny, wind protected alley between the historic structure and proposed buildings proposed along Clipper Cove Avenue. Although the alley will not be managed by Public Works as a public right of way, it will remain public and will provide vehicular and pedestrian access to Building 2 as well as the adjacent development. The design of the alley is intentionally utilitarian and restrained, with sidewalks and one way vehicular circulation from east to west.

CONTEXT

The landscape surrounding Building 2 is informed by the grand scale and simple form of the historic hangar structure, as well as the program envisioned for the building. Located at the heart of the Island Center District, Building 2 will house a grocery store along with other food and retail oriented uses. 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. DESIGN CONCEPT AND PROGRAM

The West PlazaLocated at the terminus of the retail street on the east side of the building and aligned with the historic central axis that extends from Building 1, the concept for the plaza builds on the relocation of the olive trees that remain from the Golden Gate Exposition, configured to create an elegant and mature grove set within a stabilized crushed stone plaza. The grove frames the eastern entry to the building and provides a simple, flexible space for festivals, small markets and fairs that will extend down the retail


Primary circulation and access is provided from adjacent streets to each of the historic building entries, with secondary paths and circulation between each of the spaces. The plazas on either side of the building provide open and flexible circulation as well as space for events and use by building tenants. The area around the building is consistently flat and all of the paths and plazas will be universally accessible.

STORMWATER MANAGEMENT

Runoff from the roof of the building and the impervious areas surrounding it will be treated with flows from the adjacent streets and development parcels in centralized bioretention areas in open spaces located along the edge of the Sports Park. Interim treatment areas will be provided with the storm water control plan submitted as part of the Sub Phase Application.

the pedestrian routes will be paved with simple concrete paving.

The narrow landscape area between Building 3 and California Avenue will be landscaped with a simple palette of shade tolerant plants. The east side of the building will include simple sidewalk areas and plantings and the south alley will be treated similar to the alley adjacent to Building 2 as described in the previous section.


Vehicular access to the parking area is provided from two locations along California Avenue and two locations along Clipper Cove Avenue. A central pedestrian route will connect the parking area to the building entries, reinforcing the central axis of the Island Center. Accessible parking and van spaces will be provided directly adjacent to Building 2 and the entire edge of the parking area will be set flush with adjacent plaza and separated by a detectable warning band to allow for access and loading. The area is general level, and all of the paths of travel will be universally accessible with crosswalks and curb ramps at each designated crossing.

STORMWATER MANAGEMENT

The plaza parking area will be paved with pervious concrete or asphalt to reduce stormwater runoff from this large paved area. Should the pervious paving system prove to be infeasible based on further technical design and coordination with the S.F. Public Utilities Commission, the parking area may be paved with conventional concrete or asphalt. In any case, all impervious areas will be treated with flows from the adjacent streets and development parcels in centralized bioretention areas in open spaces located along the edge of the Sports Park. Interim treatment areas will be provided with the storm water control plan submitted as part of the Sub Phase Application process.

CONTEXT

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 north edge of the space is defined by California Avenue and south edge is defined by a building parcel that is designated as part of the Trust Land and will frame views to Clipper Cove and the East Span of the Bay Bridge. Several sheds and non-historic structures adjacent to the Buildings will be removed as part of the development program.

DESIGN CONCEPT AND PROGRAM

During the Golden Gate International Exposition, Building 2 hosted the Hall of Air Transportation, and the area between the Buildings 2 and 3 was known as the Partway passage, essentially a large plaza that opened on to Clipper Cove and was space where the China Clipper other great sea planes were often on exhibit. 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 accommodating approximately 150 parking spaces and serving the grocery store as well as nearby retail and marina uses.

The plaza space is framed by two ginkgo groves that define its north and south edges and is punctuated by a series of large planting areas that will allow for large coast live oak specimen trees that will provide scale and variety. Historic elements from both the Exposition and the Navy era may be arranged in within the ginkgo groves. It is expected that the plaza parking area may be used for farmers markets and other events consistent with its designation as Trust Land and public open space. The plaza will be illuminated with large scale pole fixtures that complement the historic character of the buildings. The parking area will be paved with a combination of pervious concrete or asphalt and

Along the nearly half mile long promenade are a series of nodes which relate to the city grid. These areas have been identified for bulb outs in the Treasure Island Streetscape Masterplan to improve safety at Clipper Cove Avenue crossings. The proposed landscape creates green nodes at these bulb outs using native and adaptive planting species that manage the stormwater locally. This will also helps to break up the length of the promenade into four sub-zones, each of which includes different opportunities for seating and orientations to capture the best views. Projections from the shore are considered only where there are existing projections are located.

A Muni/AC transit bus stop is located at the West end for drop-off only. Public parking is accommodated along the entire length of Clipper Cove Avenue. Additional parking is available in surface lots in the early phases and structured parking as island density increases. On the east end, the Treasure Island Yacht Club may expand towards Clipper Cove, and so those amenities will be coordinated with the proposed promenade.

OVERVIEW

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. The surface of the promenade will be paved using different materials to visually differentiate the pedestrian zone from the cycle track. Palm trees, pole lights, and planting are located in a band between the cycle track and the pedestrian promenade to further mark the separation. The proposed grades take into account sea level rise projections. Clipper Cove has reduced wave runup due to its proximity to Yerba Buena island so the proposed grades are very similar to the existing condition. Sub-surface engineering measures will enhance the seismic stability of the promenade beyond the existing dike.

FIGURE 4.74 CULTURAL PARK CITY THROUGH ALLEE VIEW


4.2.9 CULTURAL PARK

BACKGROUND

The Cultural Park will be a focal point and civic gathering space for Treasure Island, providing an idyllic setting for the existing Chapel. Later development phases call for a collection of larger, urban-scale buildings, including an adjacent hotel and main residential tower, as well as a potential cultural building to be located on-site.

As part of a network of proximal open spaces, the Cultural Park shares visual and functional connections with Building 1 and Marina Plaza facilities across California Avenue, a proposed ferry terminal and its associated arrival plaza, and a Cityside Waterfront Plaza activating the length of the Cultural Park’s western edge. A coincidence of axial connections—north-south along Cityside Avenue, and east-west from the ferry gangway to future residential tower—locate the Cultural Park’s Chapel as central to the Island’s programmatic heart.

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.

Given the site’s vulnerability to a strong westward wind and southern sun exposure, climatic conditions are a significant driver in the site’s design approach. Likewise, the site’s subtle topography, surrounding streets, and the current conditions of the Chapel present distinct controls for site development.

DESIGN CONCEPT

A ‘cultural park’ seeks to reflect the values and desires of its place; protecting the history and heritage unique to its site; providing activities well-suited for its visitors; and offering opportunities for expression of the local neighborhood’s ever-evolving identity. Treasure Island’s Cultural Park will offer flexible open spaces that will stand up to later development.

The Park will be a place of refuge in its urban context, offering quiet relaxation for both sightseers and Island dwellers alike. A formal bosque encircles three of the site’s four sides, while an informal clustering of evergreen trees lines the fourth, to create a sense of enclosure protected against prevailing winds. Filling the Park’s central area is a flexible, open lawn—this feature offers spaces for active or passive recreation and small or large events. Set as a plinth within this lawn is a raised deck, which enfolds the historical Chapel and provides access to the structure’s existing entrances. Broad, planted terraces step down from California Avenue to the open lawn.

Site furnishings include loose tables and chairs scattered on the deck, seating areas with fixed benches along the Waterfront Promenade and public way, bicycle racks, and waste and recycling receptacles placed intermittently throughout the park. Pedestrian-scale poles provide lighting throughout the bosque; adjustable light poles and tree uplights deliver lighting to the deck and lawn areas.

PROGRAM AND ACTIVITIES

This community park has great potential for any number of events and activities, though it is not heavily programmed with fixed elements. This approach allows the Park to have the potential to continue its role as a community gathering place. Given the scale and openness of the central lawn and bosque areas, the Park can accommodate small or large events, performances, festivals, fitness events, or other local programs.


The site’s design accommodates a range of circulation patterns at its edges—visitors may pass through or encounter the Park in myriad ways. Bordered on all sites by multi-modal circulation systems, the Cultural Park is within a five- to ten-minute walk to the Island’s transit hub and primary commercial areas.

A pedestrian walk, which accommodates emergency vehicles, provides a terminus for the Island’s extensive Shared Public Way along the Park’s eastern edge. California Avenue runs along the south, offering a tour bus stop, accessible parking, and kiss-and-ride loading adjacent to the Park. A cycle track running parallel to California Avenue connects cyclists to the Eastside Commons. To the west, pedestrians and bicyclists using the Cityside Waterfront Park can find refuge in the Cultural Park’s bosque edge. The Park also interfaces with Fourth Street, which accommodates a vehicular turnaround and pedestrian connections to the waterfront.

Circulation within the Park is intentionally open and flexible. Visitors with disabilities are welcomed to the park by inclined slopes leading to the Chapel, raised deck, and recessed lawn.

STORMWATER

Porous surfaces—including decomposed granite, concrete unit pavers, and turf—cover the majority of the site, causing little to no impact to its broader watershed of ‘Site B.’
