The Potrero Yard Modernization Project will include the construction and operation of a modern, multi-story, efficient bus maintenance and storage facility equipped to serve the San Francisco Municipal Transportation Agency’s growing and future needs, as well as the construction of high-density residential development and ground floor commercial space. The controls set forth in this Section 249.98 shall be in addition to the requirements of any agreement between the City and another party for developing and operating uses at the site.
(c) Controls. In addition to controls applicable to the Public District set forth in Planning Code Sections 211 et seq., applicable provisions of the Planning Code shall apply in the Potrero Yard SUD, except as otherwise provided in this Section 249.98.
