Eventually the Lindsay administration included a new convention center between 10th and 11th avenues in the west 40s along with an extensive redevelopment of the West Side in their 1969–70 "Plan for New York City". Opposition to the massive residential displacement that this development project would have caused, and the failure of the City to complete any replacement housing, led the State Legislature to kill the convention center proposal in 1970. The City then moved the convention center site to the Hudson River, in place of Piers 84 and 86, despite the high cost of foundations and the lack of space for future expansion. That 44th Street convention center, designed by Gordon Bunshaft of Skidmore, Owings & Merrill, was approved by the Board of Estimate in 1973 despite renewed opposition from the local community. In exchange, the community received a special zoning district that offered some protection from development.
