However, the site was only zoned for 600,000 square feet (56,000 m2) and needed to purchase additional air rights from Grand Central Terminal to hit the targeted square footage.[11] The building ran into opposition trying to transfer the air rights, with New York's Manhattan Community Board 5 voting unanimously to deny the transfer in June 1989.[2] Following the Community Board's opposition, the New York City Planning Commission also unanimously disapproved of the transfer.[12] The developers sued the city in the New York Supreme Court, but the court upheld the city's decision to deny the rights transfer, effectively cancelling the project.[13]
