Some heavy hitters are lining up to knock down a proposal to landmark Brooklyn’s downtown skyscraper historic district. The Brooklyn Newspaper reported that everyone from the Brooklyn Law School to the Real Estate Board of New York say that the proposal will stunt growth in the area. Not surprisingly, as we reported back in December, the folks at 75 Livingston are still raising a stink of what it will cost them as one of the few residential buildings in the district. Proponents say that landlords are posturing to push for a major retail district and don’t want the limitations brought about by landmarking.
