One last thing...

Boggiano said the developers are planning to build a tower about 60 stories high.
That's at the bottom end of the range for their density allowances. The site is approximately 50,000 sqft. The allowable density is 20 times the area of the lot. In addition, the development may take advantage of 4 additional floors outside the density cap if those floors are dedicated for office use. This is to encourage a mixed use development.

The maximum base of the building area is 27,000 sqft and a height of 65 ft. The maximum tower floor plate is 12,900 sqft with no height limit on the tower

Worst case scenario, the developer does not take advantage of the office density bonus:

50,000 sqft x 20 times density = 1,000,000 sqft of development rights
27,000 sqft x 6 floors = 162,000 sqft in the base
1,000,000 - 162,000 = 838,000 available for the tower
838,000 / 12,900 maximum tower floor plate = 64 floors
64 + 6 = 70 floors

Best case scenario:

Developer takes advantage of the 4 free floors exempt from the maximum density calculation. The base consists of 108,000 sqft of office space in 4 floors. The full density allowance can be allocated to the tower portion of the building.

1,000,000 allowable density / 12,900 maximum tower floor plate = ~77 floors.
77 tower floors on top of 4 floor base is 81 storys.

For possible height, the zoning requires the first floor to be 18ft tall and let's assume 12 feet per floor. 18ft first floor + 80 remaining floors x 12 feet a floor = 978ft. Mechanical space doesn't count towards the density limit. I say this one is within reach of super tall status depending on how much risk the developer is willing to take.

Aside from speculation, I think we can safely modify the thread title and move this one to 60 floors based on the statement from the local councilperson.
