Last week, the City Planning Commission approved a controversial rezoning of 10 blocks in Sutton Place but included a clause that would exempt Gamma’s project from the change. Local Council member Ben Kallos, who is a co-sponsor of the rezoning application, is pushing to have the grandfather clause removed before the full council votes on the measure. The rezoning will impose “tower on a base” standards in the area, which means that 45 to 50 percent of a building would need to be built below 150 feet.

Kallos said the grandfather clause might be a “red herring” for extending the rezoning process for another two weeks or so. A change to the application, like removing the clause, would send the measure back to City Planning for review, giving Gamma more time to complete the foundation.
