OR BK 7714 PG 848 4 of 19 SECTION 6. AIRPORT HAZARD ZONES AND AIRSPACE HEIGHT LIMITATIONS. (a) In order to implement the provisions of this Ordinance, there are hereby created and established certain zones, which include all of the land lying beneath the approach, transitional, horizontal and conical zones as they apply to Zephyrhills Municipal Airport. Such zones are shown on the Zephyrhills Municipal Airport Height Zoning Map which is attached to this Ordinance and made a part hereof. (b) Except as otherwise provided in this Ordinance, no structure or tree shall be erected, altered, allowed to grow, or maintained in any zone created by this Ordinance to a height in excess of the height limit established in this section for such zone. Where an area is covered by more than one height limitation under this section, the more restrictive limitation shall prevail. The various zones are established and defined as follows: (1) Primary Zone: An area longitudinally centered on a runway, extending 200 feet beyond each end of that runway with the width so specified for each runway for the most precise approach existing or planned for either end of the runway. No Structure or Obstruction will be permitted within the primary zone that is not part of the landing and takeoff area, and is of a greater height than the nearest point on the runway centerline. The width of the primary zone is as follows: Runways 4 and 22: 500 feet for Non-Precision-Instrument Runways having visibility minimums greater than three-fourths statute mile. Runways 18 and 36: 1,000 feet for Precision Instrument Runways having visibility minimums less than three-fourths statute mile. The width of the primary zone of a runway will be that width prescribed in this section for the most precise approach existing or planned for either end of that runway. No Structure or Obstruction will be permitted within the primary zone that is not part of the landing and takeoff facilities and is of a greater height than the nearest point on the runway centerline. (2) Horizontal Zone: The area around each civil Airport with an outer boundary the perimeter of which is constructed by swinging arcs of specified radii from the center of each end of the primary zone of each Airport's runway and connecting the adjacent arcs by lines tangent to those arcs. The radius of each arc is: Runways 4, 22, 18, and 36: 10,000 feet for all runways not designated as visual or utility. The radius of the arc specified for each end of a runway will have the same arithmetical value. That value will be the highest composite value determined for either end of the runway. When a 5,000-foot arc is encompassed by tangents connecting two adjacent 10,000-foot arcs, the 5,000- foot arc shall be disregarded on the construction of the perimeter of the horizontal zone. No Structure or Obstruction will be permitted in the horizontal zone that has a height greater than 150 feet above the Airport Height. (3) Conical Zone: The area extending outward from the periphery of the horizontal zone for a distance of 4,000 feet. Height limitations for Structures in the conical zone are 150 feet above Airport Elevation at the inner boundary with permitted height increasing one foot vertically for every 20 feet of horizontal distance measured outward from the inner boundary to a height of 350 feet above Airport Height at the outer boundary. (4) Approach Zone: An area longitudinally centered on the extended runway centerline and extending outward from each end of the primary zone. An approach zone is designated for each runway based upon the type of approach available or planned for that runway end. The inner edge of the approach zone is the same width as the primary zone and it expands uniformly to a width of: 4
