Within the zoning code, an important distinction is made between Wide Streets, which are greater than 75 feet in width, and Narrow Streets. In this context, the constructed width of Park Avenue, at 140 feet, reveals an oversized and underutilized void forced by the dimensions of the infrastructure it incorporated. As a basis for the infill, the extra width of Park Avenue is redefined into two narrow street conditions which would allow for a slender building to be permitted within New York City zoning. The possibility of an inserted sectional space is in keeping with the intent of zoning and the city fabric.
