Hudson Yards might have been too challenging for Tishman

Tishman Speyer told the MTA before backing out of a deal to develop Hudson Yards that a pending rezoning of the area created too much risk, with the chance that the community board or City Council could have forced changes. But looming challenges could have caused the Speyers to backtrack. It had no anchor tenant lined up. It needed $2 billion in financing for a platform over an active rail yard. And the fate of an extended No. 7 subway line looked uncertain.
