Three architect-developer teams presented their plans for a massive downtown redevelopment scheme in San Francisco last week and the public now has until September 17 to comment on them. The designers are vying in a competition for the Landmark Transbay Transit Center and Tower: a 1-million-square-foot, multimodal transit hub and adjacent skyscraper on a roughly 12-acre site within a 40-acre downtown redevelopment district.

Transbay’s architect-developer teams are Rogers Stirk Harbour + Partners—formerly the Richard Rogers Partnership—and Forest City Enterprises with MacFarlane Partners; Skidmore Owings & Merrill and the Rockefeller Group Development Corporation; and Pelli Clarke Pelli Architects and Hines.

The centerpiece of the Richard Rogers-led team’s design is a 1,000-foot-tall tower that would be capped with an electricity-generating wind turbine. The building contains a mix of uses including hotel rooms and affordable housing, the design team wrote in its project description, making it a “microcosm of the city and bay region itself.” Similarly, the crown of SOM’s proposed skyscraper would also contain wind turbines as well as photovoltaic panels. The 1,200-foot-tall building’s first floor would be raised 100 feet above street level, creating a vast covered “portal” into two civic spaces, including a Performing Arts Park. And, lastly, Cesar Pelli’s proposal calls for a slender, obelisk-like tower with a 5.4-acre landscaped park in front of it.

The redevelopment is being overseen by the Transbay Joint Powers Authority (TJPA), which is controlled by the City and County of San Francisco, the Alameda-Contra Costa Transit District, and the Peninsula Corridor Joint Powers Board. The TJPA’s board will select a final proposal on September 20. Members of the public may comment on the three proposed designs by visiting the TJBA’s Web site, transbaycenter.org.
