The center lines of such approach paths or planes shall be separated by an arc of at least ninety degrees. The remaining peripheral area surrounding the landing and take-off area shall be free and clear of obstructions at an angle of two feet horizontally to one foot vertically to a lateral distance of 250 feet from the landing and take-off area.
   (c)    No approach path shall be used and no helicopter shall be flown at an elevation of less than 500 feet over a residence building, school or other public building, or closer than 200 feet to any other building, structure, tree or public highway, except for the purpose of landing or taking off from an approved helistop.
