§ 151.212  HEIGHT LIMITATIONS.
   (A)   Except as otherwise provided in the section, no structure or tree shall be erected, altered, allowed to grow, or maintained in any zone created by this chapter to a height in excess of the height limit herein established for the zone.  The height limitations are hereby established for each of the zones in question as follows:
      (1)   Precision instrument approach zone.  One foot in height for each 50 feet horizontal distance beginning at a point 200 feet from and at the elevation of the end of the precision instrument runway and extending to a distance of 10,200 feet from the end of the runway, thence 1 foot in height for each 40 feet horizontal distance to a point 50,200 feet from the end of the runway;
      (2)   Nonprecision instrument approach zones.  For the east-west nonprecision zone - 1 foot in height for each 34 feet horizontal distance beginning at the ends of the primary zone and extending for a distance of 10,000 feet. For the north-south nonprecision zone - 1 foot in height for each 20 feet horizontal beginning at the ends of the primary zone and extending for a distance of 5,000 feet;
      (3)   Transition zones.  One foot in height for each 7 feet horizontal distance beginning at any point on the sides of the primary zone and approach zones, extending to a height of 150 feet above the airport elevation which is 777 feet above mean sea level. Further, where the precision instrument approach zone projects through and beyond the conical zone, a height limit of 1 foot for each 7 feet horizontal distance shall be maintained beginning at the edge of the instrument approach zone measured normal to the centerline of the runway extended;
      (4)   Horizontal zone.  One hundred and fifty feet above the airport elevation or a height of 927 feet above mean sea level; and
      (5)   Conical zone.  One foot in height for each 20 feet horizontal distance beginning at the periphery of the horizontal zone, extending to a height of 350 feet above the airport elevation;
      (6)   Primary zone.  The elevation of any point on the primary zone is the same as the elevation of the nearest point on the runway centerline.
   (B)   Where an area is covered by more than one height limitation, the more restrictive limitation shall prevail.  Nothing in this section shall be construed as prohibiting the growth, construction or maintenance of any tree or structure to a height consistent with the provisions of this chapter.
