The air-rights transfers needed the approval of several agencies.[1] In August 1984, the New York City Board of Estimate voted to allow the sale of air rights.[2][65] The LPC was scheduled to hold a hearing for the proposed sale in November 1984, but an unrelated controversy over another landmark candidate took up all the time allotted for discussing the air-rights sale.[66] The LPC granted the project a "certificate of appropriateness" in January 1985,[67] which allowed the LPC to apply for a special zoning permit from the New York City Planning Commission (CPC) for the air-rights transfer.[68] Several agencies then needed to approve the tower itself. Following objections from members of the Board of Estimate and CPC, some elements of City Center Tower were downsized.[7] The CPC approved the tower in June 1985,[69] followed by the Board of Estimate that August.[70]
