They're planning to two floors to the Weston garage.
This link has the building elevations and some renderings of what they're planning.
This will add 30+ feet of height to the garage with a total of 12 levels and 116 feet in height to the main roof (top level) of the garage. Plus, the elevator tower will go up another 14 feet 5 3/4 inches from what I measured. So overall, the new height of the garage will be 130 feet 9 3/4 inches tall.
They're also planning some new lighting for the top of the garage using what I'm guessing is LED lighting.
