It’s back to the mysterious and obscure, yet powerful, Board of Standards and Appeals for the controversy-plagued 360 Smith Building in Carroll Gardens. First, the issue was its Heavy Metal Look designed by Robert Scarano. Subsequently the sticking point was the building’s height. In the meantime, there was a zoning changing on the block on which the building is actually located, limited it to 55 feet in height rather than the planned 70 feet. The developer says the foundation is complete enough for the building to be grandfathered to 70 feet. The Department of Buildings says the foundation was only 20 percent done at the time of the zoning change. At the last meeting, the BSA decided not to decide. And this time? We are hearing rumblings that “the fix is in” and that the developer might actually win, despite the evidence from the DOB. The session is at 10AM tomorrow at 40 Rector Street, 6th Floor, Hearing Room (E). The public is, of course, allowed to attend and speak.
