COMMERCIAL AND INDUSTRIAL FLOOR AREA

One of the major factors pointing up the need for a zoning resolution back in 1916 was the construction of massive office buildings in some areas of the City. This overwhelming commercial bulk has made many of our streets into dark canyons.

While it is recognized that in the critical Commercial Districts in Central Manhattan there is need for reasonably high Floor Area Ratios, the proposed Resolution varies the maximum FAR's depending on the location of the District. In Central areas, FAR's are permitted to go as high as 15.00, and - by means of the plaza bonus - they can go up to 18.00. In the outlying Districts maximum permitted Floor Area Ratios are lower and are not as important in governing the degree of development, since the provision of off-street parking facilities on the site strongly influences the relationship between floor area and lot area. 

The maximum industrial FAR's, like the commercial levels, were determined on standards of good, yet profitable construction. Industrial plant construction in New York has followed the trend toward one-story, low bulk buildings. A sample survey of half the plants built in the City in recent years showed an average Floor Area Ration of .72, with only 3 per cent of the single occupancy structures exceeding FAR 1.10.
