               Except as otherwise provided in this chapter, no structure shall be erected, altered,
               or maintained in any zone created by this chapter to a 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:

               <p class="content2">
                  <span class="ital">Precision instrument runway approach zone.</span> Slopes 50 feet outward for each foot upward beginning at the end of and at the same
                  elevation as the primary surface and extending to a horizontal distance of 10,000
                  feet along the extended runway centerline; thence slopes upward 40 feet horizontally
                  for each foot vertically to an additional horizontal distance of 40,000 feet along
                  the extended runway centerline.

                  same elevation as the primary surface and the approach surface, and extending to a
                  height of 150 feet above the airport elevation which is 18 feet above mean sea level.
                  In addition to the foregoing, there are established height limits sloping seven feet
                  outward for each foot upward beginning at the sides of and at the same elevation as
                  the approach surface, and extending to where they intersect the conical surface. Where
                  the precision instrument runway approach zone projects beyond the conical zone, there
                  are established height limits sloping seven feet outward for each foot upward beginning
                  at the sides of and at the same elevation as the approach surface, and extending a
                  horizontal distance of 5,000 feet measured at 90-degree angles to the extended runway
                  centerline.
