For an arena permitted pursuant to Section 74-41 within Pennsylvania Station Subarea B4, the City Planning Commission may, by special permit, modify the applicable provisions of Sections 32-63 (Permitted Advertising Signs) to allow advertising signs, 32-64 (Surface Area and Illumination Provisions) to allow increased surface area along specified streets and 32-65 (Permitted Projection or Height of Signs), provided such signs comply with the conditions of paragraph (a) and the findings of paragraph (b) of this Section, as follows:

(a)        Conditions

(1)        no sign shall extend to a height greater than 85 feet above curb level ;

(2)        all signs located below a height of 12 feet above curb level shall be limited in location and aggregate surface area to 550 square feet on the West 31st Street frontage of Subarea B4, 250 square feet on the West 33rd Street frontage of Subarea B4 and 850 square feet on the Eighth Avenue frontage of Subarea B4; and

(3)        all signs located above a height of 12 feet above curb level shall be limited in location and aggregate surface area to 5,500 square feet within the through lot fronting on Eighth Avenue, 3,000 square feet within each corner lot fronting on Eighth Avenue, 3,000 square feet within the through lot portion of the West 31st Street frontage of Subarea B4 and 3,000 square feet within the through lot portion of the West 33rd Street frontage of Subarea B4.

(b)        The Commission shall find that the location and placement of such signs is appropriate in the relationship to buildings and uses on the zoning lot and to adjacent open areas, and would be compatible with the character of the arena site, including its use as an entryway to Pennsylvania Station, and of the surrounding area.

For purposes of calculating the height of any sign permitted pursuant to this Section, curb level shall be defined as 30.755 feet above Manhattan datum.

The Commission may prescribe additional conditions and safeguards to minimize adverse effects on the character of the surrounding area, including limitations on the number, size and location of arena signs permitted pursuant to the district regulations.
