Document Description
The Sobrato Organization is proposing to construct an approximately 249,500-gsf office building (Building 3) and an approximately 349,200 gsf parking structure as part of the Commonwealth: Building 3 Project (Project). Building 3 and the parking structure would replace most of the existing surface parking lot. When combined with the existing buildings at the Project site, the Project would result in three office buildings with a combined floor area of approximately 509,420 gsf and a FAR of 88 percent. The approximately 349,200 gsf parking structure would accommodate 1,061 parking spaces within four stories. The Jefferson Site would be converted from an existing surface parking lot to a 0.73-acre community park (Jefferson Park) that would be privately owned, but publicly accessible.
