The only taller buildings in the US would be the Sears Tower (1,451 feet) in Chicago and New York City's Empire State Building (1,250 feet). They would eclipse the tallest existing building in the West, Transamerica Pyramid (853 feet), by more than 30 stories.

The filing with the planning commission was an application to start the required environmental review process as opposed to a formal design proposal, where the size and shape of the towers could be altered. The submitted documents included a map of the site and a description of the buildings but no architectural renderings. Mark Solit, a member of the development team, could not be reached over the weekend for comment.

As submitted, the plan calls for 2.9 million sf of condominiums, hotel rooms and office space in two 1,200-foot towers, two 900-foot towers and one 600-foot tower rising from a two-acre site that currently holds relatively small, class C buildings totaling about 250,000 sf. The description calls for the towers to be skinned with white terra cotta tiles and for the development as a whole to earn a "gold" rating from the US Green Building Council. At $400 per sf, the total development cost would be $1.16 billion.
