The deal to rezone the West Side Yards is still not done. M.T.A. board member Mitch Pally, who had been a thorn in the side of Chairman Peter Kalikow before, pointed out at this morning’s meeting that no where did the memorandum of understanding he was asked to vote on stipulated that the city would bear the costs of buying property for the No. 7 line extension. “We will,” Kalikow said. “The agreement will be amended appropriately.” The board voted unanimously anyway, though the amendment will also have to be approved by the city.
