Every person, firm or corporation intending to establish and use a helistop within the City shall first submit plans for approval to the Mayor, 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, a map of the proposed routes of the flights, size, type and manufacture of equipment intended to be used and 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 helistop indicating their heights and drawings of flight and approach paths within 1,000 feet of the helistop and lighting, access and drainage plans.
(c) A report by a professional engineer approved by the Building Inspector, showing that the roof structure or platform is designed to support concentrated loads on any one square foot equivalent to three-fourths gross weight of the largest helicopter to be accommodated.
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 normally suffice.
