The zoning in NYC should be comprehensively revisited/revised in any event. Zoning in NYC is generally an exclusionary process, rather than a hierarchical process - in most places with zoning laws, the rules are hierarchical, meaning that a lower zoned use cannot be conducted in a higher zoned area, but a higher zoned use can always be conducted in a lower zoned area. In NYC, zoning is exclusive, which means that if an area is zoned commercial, even light commercial, no other use can be conducted in that area, including housing or industrial. As a result, when an area zoned industrial or commercial ceases to be used for that purpose - for example, because it's too expensive to maintain those kinds of businesses in NYC and the companies relocate elsewhere - the area becomes abandoned rather than being repurposed for another use, such as housing.
Just one more in a long list of prog/lib "improvements" that have done nothing but damage the city's fabric.
