Every person intending to establish and use a helistop within the City shall first submit plans for approval to the Director of Public Safety, consisting of the following:
(a) A statement as to the intended use of the helistop, whether public or private, commercial or otherwise, the identity and financial responsibility of the management, the frequency of flights, the size, type and manufacture of equipment intended to be used and the hours of operation;
(b) A plan of the proposed site showing dimensions of the entire usable areas, dimensions of actual landing and take-off areas, all obstructions within 1,000 feet of the heliport (indicating their heights), drawings of flight and approach paths within 1,000 feet of the heliport and lighting, access and drainage plans; and
(c) (1) A report by a professional engineer approved by the Building Commissioner, showing that the roof structure or platform is designed to support concentrated loads on any one square foot equivalent to three-fourths of the gross weight of the largest helicopter to be accommodated.
(2) It is not a requirement of this subsection that every square foot of the entire roof area be stressed to withstand such impact load simultaneously, but only that area with which the main landing gear of the helicopter will be in contact. A simple load distributing pad, twenty feet by twenty feet by four inches, constructed of a noncombustible material, will suffice in the helistop.
