 With the adoption of the Transit Center District Plan in 2012, height limits were raised for several parcels in the vicinity of the Transit Center.Among the parcels zoned for taller buildings are 50 First Street, 181 Fremont Street, 350 Mission Street, Golden Gate University's campus at 536 Mission Street, the proposed Palace Hotel Residential Tower, and the Salesforce Tower site.Following the 1989 Loma Prieta earthquake, the Embarcadero Freeway was torn down, opening up a number of blocks for development.
