increased gross floor area can be accommodated in a building or development which conforms to the applicable building standards of this Article and the design guidelines of the Mission
Bay Plan.
(e) Recording Transfers. The documentation required by Section 127(b) and (c) shall be required to effect a transfer of gross floor area under this section.
