               Except as otherwise provided in this article, no structure or tree shall be erected,
               altered, allowed to grow, or be maintained in any zone created by this article to
               the height in excess of the applicable height limit herein established for such zone.
               Such applicable height limitations are hereby established for each of the zones in
               question as follows:

                  are established height limits sloping seven feet outward for each foot upward beginning
                  at the sides of and the same elevation as the approach surface, and extending to where
                  they intersect the conical surface. Where the precision instrument runway approach
