The 1982 Manhattan Core parking zoning amendments sought, in the words of the City Planning Commission's report, "to institute land use controls over off-street parking which are consistent with environmental policies and sensitive to the concerns of business and development interests in the City." This 2011 study evaluates the 1982 report on parking in Manhattan. It concludes that, on the whole, Manhattan core parking regulations from 1982 remain compatible with population and job growth in the central business district. However, development of land, car ownership, commuting, growing use of parking facilities by residents, and complex and uninforced zoning regulations require targeted modifications that could update the regulations to reflect contemporary conditions, improve functionability, and provide clear and predictable application.
