Park is the Top Icing Layer of Transit Center

The new Salesforce Transit Center Park opened this past weekend atop the transit center.

SAN FRANCISCO—During the course of San Francisco’s history, urban parks have often served as the stimulus for neighborhood development. But how do you create a four-block park spanning 5.4 acres in a highly developed area of downtown? You build it on a roof.

And what a roof it is. The new Salesforce Transit Center Park opened this past weekend atop the transit center, providing green space in a downtown area surrounded by the high-rises of Trulia and BlackRock, and of course, Salesforce Tower, looming above. The park accomplishes multiple purposes not only for passengers but also for this newly developing area, as it increases the amount of open space in the neighborhood by 17%, according to the Transbay Joint Powers Authority.
