Tony: Thought you might want this. It's the OMB decision allowing Ritz Carlton to build up to its planned height of 684 ft.
Height is on page 2:

Also the height you mentioned for 40 wellesley in the diagrams doesn't include the the swoop at the top of the building (I know I'm being picky. Sorry) . Total height is 533 ft.
