A recent site visit to Treasure Island by YIMBY reveals significant progress has been made for the region’s most active construction project. Cranes and rising concrete have only started to divulge the scale of the 405-acre vision, nearly three decades in the making, that will redevelop San Francisco’s storied artificial island with a mixed-use urban neighborhood populated by around eight thousand homes. The Treasure Island Community Development joint venture sponsors the project.
TICD is a partnership with Stockbridge Capital Group, Wilson Meany, and Lennar Corporation. The three developers are overseeing the roughly $6 billion redevelopment of Treasure Island and Yerba Buena Island with housing, including replacement residences for existing residents and new affordable apartments. Plans include new construction and the adaptive reuse of existing structures to produce retail, hotels, and offices surrounded by new public open space.
Treasure Island Ferry
Our visit to Treasure Island yesterday was made with the new Treasure Island ferry, which unfortunately does not connect with Google Maps. The ten-dollar round-trip ticket purchased in-person or online will get passengers on the approximately ten-minute ride from the Ferry Building to the island in the middle of the Bay. The 55-seat boat sees just a handful of passengers each hour nowadays, according to the crew. However, demand is expected to increase once the island population surges in the coming years, and a larger boat will be necessary.
The ferry station on the island unloads just outside the semicircular 1939 Fair Building. Behind the Treasure Island Administration Building, land has already been leveled for the 117-unit Parcel B with design by Stanley Saitowitz Natoma Architects.
Along with the aerial pictures, new renderings have been shared of Parcel C2.4, the tallest building currently under construction on Treasure Island. The 22-story high-rise at 39-49 Burton Street will create 250 new rental units. It is the first of several towers expected to form the island’s skyline. Concrete has reached the fourth floor, and the tower is expected to open next year. Groundbreaking for the Parcel C2.4 tower was announced in July of last year by Webcor, the general contractors.
The 220-foot tall structure will yield around 313,240 square feet from the 0.84-acre property. The ground level will include the residential lobby, live-work units, a broad courtyard, and a corner café. Unit sizes will vary with 15 studios, 16 junior one-bedrooms, 93 one-bedrooms, 115 two-bedrooms, and 11 three-bedrooms. Parking will be included for 109 cars. GLS is responsible for the landscape architecture, which includes the podium-top courtyard and some sidewalk improvements.
David Baker Architects is responsible for the design. The white tower will sit on top of a four-to-five-story articulated townhome-style podium. The folded tower skin will express a repetitive bay window pattern, playing off the region’s architectural vernacular. The design style, made most popular with MIRA SF by Studio Gang, has been proliferating with several more projects in the pipeline.
Immediately beside soon-to-be-22-story Parcel C2.4, excavation work has started for Portico at C2.2, a 148-unit midrise complex designed by Mark Cavagnero Associates. The same architects are responsible for the 178-unit Hawkins apartment, for which the site has been cleared.
Crews are working on finishing touches to the Maceo May Apartments. The 105-unit project will provide housing for formerly homeless veterans and their families. The project will be delivered to the Chinatown Community Development Center and Swords to Plowshares, a Bay Area-based developer. Mithun is the project architect.
Across from Maceo May Apartments, another affordable housing project has broken ground. The seven-story Star View Court at 78 Johnson Street will eventually add 138 new homes with services provided by Catholic Charities and Mercy Housing. Completion is expected by next year. Concrete has reached the third floor.
The first construction phase will be connected by Cityside Park, a walkable thoroughfare for pedestrians and cyclists. The public amenity is being designed by CMG Landscape Architecture. The shared public way will extend through blocks C2 and C3 to the Cultural park and existing chapel. Across from the cultural park, the fair building will contain a new landscaped space facing the waterfront plaza, while the rear will overlook Marina Plaza.
Treasure Island Overview
While Parcel C2.4 is currently the tallest project under construction, it will be overshadowed once construction starts on Treasure Islands’ Parcel C2.1, a 31-story tower with a 345-foot rooftop height. The Handel Architects-designed addition will feature 265 apartments.
The master plan was designed by Skidmore Owings and Merrill, who oriented the project around three compact neighborhoods with public transportation emanating from the mixed-use hub with connections to San Francisco. Of the 8,000 units, plans include 421 townhomes, 2,232 low-rise units, 519 mid-rise units, 3,144 tower units, and 1,684 to be managed by Authority Housing.
For now, the Treasure Island and Yerba Buena have seen the opening of Bristol, Maceo May Apartments, and Clipper Cove Beach. With the landscaping and five more projects under construction at the moment, there are nearly a thousand units either complete or rising. The first phase will open around 1,500 units. Parcel C2.4 is expected to open by 2024. Completion of the master plan is anticipated by 2036.
