This section is intended to recognize the importance of preventing hazards to aircraft navigation that may result from the height of structures in areas surrounding certain helipads. The regulations create the appropriate zones and applicable boundaries where height restrictions for structures or uses of land will be limited so as not to obstruct the airspace required for aircraft landing or taking off from certain helipads, or would otherwise be hazardous to aviation operations during landing or take-off. The limitations intended to mitigate such obstructions are established in order to protect the safety and general welfare of helicopter operators and passengers, as well as to protect the safety and general welfare of property and occupants of land in the vicinity of a helipad and to continue to foster economic growth for the region.
