ZDO 713: Public Use Airport And Safety Overlay Zones

713.01 Purpose

Section 713 is adopted to implement Oregon Revised Statutes 836.600 through 836.630 and policies of the Comprehensive Plan as they relate to public use airports. When applied, it provides for their continued operation and vitality consistent with state law by allowing certain compatible airport related commercial and recreational uses.  It also provides for safety standards to promote air navigational safety at such public use airports and to reduce the potential for safety hazards for property and for persons living, working, or recreating on lands near such airports.

713.02 Application

This special use zoning district may be applied to publicly owned airports  that are shown in the records of the Oregon Department of Aviation (ODA) on December 31, 1994.  It also may be applied to those privately owned, public use airports identified pursuant to Oregon Revised Statutes (ORS) 836.610(3) by the ODA as providing important links in air traffic in Oregon, providing essential safety or emergency services, or are of economic importance to the County.

The boundaries of this special use district are coterminous with airport boundaries as described in Oregon Administrative Rules (OAR) 660-013-0040.  The boundaries of safety overlay zones radiate from points at the ends of the airport's primary surface as described in OAR 660-013-0070(1)(a) and Exhibits 1 and 4 that accompany that rule.  The definitions in Subsection 713.03 are consistent with ORS Chapter 836, OAR 660-013, and Exhibits 1 and 4 of that rule.

If an airport that had this special use zoning district applied is removed from the State's list of airports in a manner described in ORS 836.610, the application of this special use zoning district is automatically terminated.

713.03 Definitions

  1. Aircraft.  Means airplanes and helicopters, but not hot air balloons or ultralights.
  2. Airport.  The strip of land used for taking off and landing aircraft, together with all adjacent land used in connection with the aircraft landing or taking off from the strip of land, including but not limited to land used for existing airport uses.
  3. Airport Elevation.  The highest point of an airport's usable runway, measured in feet above mean sea level.
  4. Airport Imaginary Surfaces.  Imaginary areas in space and on the ground that are established in relation to the airport and its runways.  Imaginary surfaces are defined by the primary surface, runway protection zone, approach surface, horizontal surface, conical surface and transitional surface.
  5. Airport Noise Impact Boundary.  Areas located within 1,500 feet of an airport runway or within established noise contour boundaries exceeding 55 Ldn.
  6. Airport Sponsor.  The owner, manager, or other person or entity designated to represent the interests of an airport.
  7. Approach Surface.  A surface longitudinally centered on the extended runway centerline and extending outward and upward from each end of the primary surface.
    1. The inner edge of the approach surface is the same width as the primary surface and it expands uniformly to a width of:
      1. 1,250 feet for a utility runway having only visual approaches;
      2. 1,500 feet for a runway other than a utility runway with only visual approaches;
      3. 2,000 feet for a runway with a non-precision instrument approach;
      4. 3,500 feet for a non-precision instrument runway other than utility, having visibility minimums greater than three-fourths statute mile;
      5. 4,000 feet for a non-precision instrument runway, other than utility, having a non-precision approach with visibility minimums as low as three-fourths statute mile; and
      6. 16,000 feet for precision instrument runways.
    2. The approach surface extends for a horizontal distance of:
      1. 5,000 feet at a slope of 20 feet outward for each foot upward for all utility and visual runways;
      2. 10,000 feet at a slope of 34 feet outward for each foot upward for all non-precision instrument runways, other than utility; and
      3. 10,000 feet at a slope of 50 feet outward for each one foot upward, with an additional 40,000 feet at a slope of 40 feet outward for each one foot upward, for precision instrument runways.
    3. The outer width of an approach surface will be that width prescribed in this subsection for the most precise approach existing or planned for that runway end.
  8. Conical Surface.  A surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 to one for a horizontal distance of 4,000 feet.
  9. Hazard.  All hazards within and around airports shall be as determined by the Oregon Department of Aviation or Federal Aviation Administration (FAA).
  10. Heliports.  A heliport is an area of land, water, or structure designated for the landing and take-off of helicopters or other rotorcraft.  The heliport overlay zone applies the following imaginary surfaces.  The heliport approach surfaces begin at each end of the heliport primary surface and have the same width as the primary surface.  They extend outward and upward for a horizontal distance of 4,000 feet where their width is 500 feet.  The slope of the approach surfaces is eight to one for civilian heliports and 10 to one for military heliports.  The heliport primary surface coincides in size and shape with the designated takeoff and landing area of a heliport.  The heliport primary surface is a horizontal plane at the established heliport elevation.  The heliport transitional surfaces extend outward and upward from the lateral boundaries of the heliport primary surface and from the approach surfaces at a slope of two to one for a distance of 250 feet measured horizontally from the centerline of the primary and approach surfaces.
  11. Horizontal Surface.  A horizontal plane 150 feet above the established airport elevation, the perimeter of which is constructed by swinging arcs of specified radii from the center of each end of the primary surface of each runway of each airport and connecting the adjacent arcs by lines tangent to those arcs.  The radius of each arc is:
    1. 5,000 feet for all runways designated as utility or visual.
    2. 10,000 feet for all other runways.
    3. The radius of the arc specified for each end of a runway will have the same arithmetical value.  That value will be the highest 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 surface.
  12. Non-Precision Instrument Runway.  A runway having an existing instrument approach procedure utilizing air navigation facilities with only horizontal guidance, or area type navigation equipment, for which a straight-in non-precision instrument approach has been approved, or planned, and for which no precision approach facilities are planned or indicated on an FAA-approved airport layout plan or other FAA planning document.
  13. Other than Utility Runway.  A runway that is constructed for and intended to be used by turbine-driven aircraft or by propeller-driven aircraft exceeding 12,500 pounds gross weight.
  14. Precision Instrument Runway.  A runway having an existing instrument approach procedure utilizing air navigation facilities that provide both horizontal and vertical guidance, such as an Instrument Landing System (ILS) or Precision Approach Radar (PAR).  It also means a runway for which a precision approach system is planned and is so indicated by an FAA-approved airport layout plan or other FAA planning document.
  15. Primary Surface.  A surface longitudinally centered on a runway.  When a runway has a specially prepared hard surface, the primary surface extends 200 feet beyond each end of that runway.  When a runway has no specially prepared hard surface, or planned hard surface, the primary surface ends at each end of that runway.  The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway centerline.  The width of the primary surface is:
    1. 250 feet for utility runways having only visual approaches;
    2. 500 feet for utility runways having non-precision instrument approaches;
    3. For other than utility runways the width is:
      1. 500 feet for visual runways having only visual approaches;
      2. 500 feet for non-precision instrument runways having visibility minimums greater than three-fourths statute mile;
      3. 1,000 feet for a non-precision instrument runway having a non-precision instrument approach with a visibility minimum as low as three-fourths statute mile, and for precision instrument runways.
  16. Public Assembly Facility.  A permanent or temporary structure or facility, place or activity where concentrations of people gather in reasonably close quarters for purposes such as deliberation, education, worship, shopping, employment, entertainment, recreation, sporting events, or similar activities.  Public assembly facilities include, but are not limited to, schools, places of worship, conference or convention facilities, employment and shopping centers, arenas, athletic fields, stadiums, clubhouses, museums, and similar facilities and places, but do not include parks, golf courses or similar facilities unless used in a manner where people are concentrated in reasonably close quarters.  Public assembly facilities also do not include air shows, structures or uses approved by the FAA in an adopted airport master plan, or places where people congregate for short periods of time such as parking lots or bus stops.
  17. Runway.  A defined area on an airport prepared for landing and takeoff of aircraft along its length.
  18. Runway Protection Zone (RPZ).  An area off the runway end used to enhance the protection of people and property on the ground.  The RPZ is trapezoidal in shape and centered about the extended runway centerline.  The inner width of the RPZ is the same as the width of the primary surface.  The outer width of the RPZ is a function of the type of aircraft and specified approach visibility minimum associated with the runway end.  The RPZ extends from each end of the primary surface for a horizontal distance of:
    1. 1,000 feet for utility runways.
    2. 1,700 feet for other than utility runways having non-precision instrument approaches.
    3. 2,500 feet for precision instrument runways.
  19. Structure.  Any constructed or erected object which requires location on the ground or is attached to something located on the ground.  Structures include but are not limited to buildings, decks, fences, signs, towers, cranes, flagpoles, antennas, smokestacks, earthen formations and overhead transmission lines.  Structures do not include paved areas.
  20. Transitional Surface.  Those surfaces that extend upward and outward at 90 degree angles to the runway centerline and the runway centerline extended at a slope of seven feet horizontally for each foot vertically from the sides of the primary and approach surfaces to the point of intersection with the horizontal and conical surfaces.  Transitional surfaces for those portions of the precision approach surfaces which project through and beyond the limits of the conical surface, extend a distance of 5,000 feet measured horizontally from the edge of the approach surface and at a 90 degree angle to the extended runway centerline.
  21. Utility Runway.  A runway that is constructed for and intended to be used by propeller driven aircraft of 12,500 pounds maximum gross weight or less.
  22. Visual Runway.  A runway intended solely for the operation of aircraft using visual approach procedures, where no straight-in instrument approach procedures or instrument designations have been approved or planned, or are indicated on an FAA-approved airport layout plan or any other FAA planning document.
  23. Water Impoundment.  Includes wastewater treatment settling ponds, surface mining ponds, detention and retention ponds, artificial lakes and ponds, and similar water features.  A new water impoundment includes an expansion of an existing water impoundment except where such expansion was previously authorized by land use action approved prior to the effective date of Section 713.
