The proposed development to rise at Fourth and Harrison has been redesigned by HOK for Boston Properties, incorporating a more curvilinear approach which would rise up to a height of 185 feet and yield 765,600 square feet of office space; 34,500 square feet of “modern” Production, Distribution and Repair (PDR) space on the ground floor; 16,100 square feet of publicly accessible open space (POPOS); 4,000 square feet of retail; and a basement garage for a few hundred cars.
The aforementioned POPOS includes a mid-block paseo between Harrison and Perry. And in an effort to pave the way for the project’s approval, the project team is positioning to dedicate 15,000 square feet of the project’s land on the eastern side of the paseo for the development of an affordable housing project.
And then there’s the much bigger story, which is key to the proposed development of 725 Harrison Street but in the context of which the Harrison Street project actually plays a bit part: San Francisco’s Central SoMa Plan.
If approved as proposed and massed at full build-out above, the adoption of the Central SoMa Plan would allow for the development of new office space for up to 45,000 workers and 7,500 units of housing to rise up to 400-ish feet in height in the area roughly bounded by Folsom, Second, Townsend and Sixth Streets.
And while San Francisco’s Proposition M currently limits the amount of office space allowed to be built in the city each year, a proposed ballot measure which is about to start gathering signatures would allow qualifying office developments in Central SoMa to evenly amortize their total square-footage over a ten-year period versus in the year when the projects are approved.
In terms of timing, while the schedule has slipped, the approval process is formally underway and San Francisco’s Planning Department is now anticipating that the Central SoMa Plan should be ready for adoption by San Francisco’s Board of Supervisors in the Spring of 2018.
