Section 1. Purpose. The purpose of this ordinance is to create an airport overlay zone that:

·        regulates and restricts the height of constructed structures and objects of natural growth

·        defines noise impact boundaries

·        considers safety issues around the airport

·        regulates and restricts the use of the real property on and in the vicinity of the above designated airport,

·        creates the appropriate zone(s), establishes the boundaries thereof, and provides for changes in the restrictions and boundaries of such zones,

·        creates the permitting process for use within said zone(s),

·        defines certain terms used herein,

·        and, provides for the enforcement, violation penalties, appeal process, and judicial review.

This Ordinance is adopted pursuant to the authority conferred by Title 67 Chapter 65 Idaho Code, Local Land Use Planning. It is hereby found that an obstruction has the potential for endangering the lives and property of users of Boundary County Airport, and property or occupants of land in its vicinity; that an obstruction may affect existing and future instrument approach minimums of Boundary County Airport; and that an obstruction may reduce the size of areas available for the landing, takeoff, and maneuvering of aircraft, thus tending to destroy or impair the utility of Boundary County Airport and the public investment therein. Accordingly, it is declared:

  1. That the creation or establishment of an obstruction has the potential of being a public nuisance and may injure the region served by Boundary County Airport;
  2. That it is necessary in the interest of the public health, public safety, and general welfare that the creation or establishment of obstructions that are a hazard to air navigation be prevented; and
  3. That the prevention of these obstructions should be accomplished, to the extent legally possible, by the exercise of the police power without compensation.

It is further declared that the prevention of the creation or establishment of hazards to air navigation, the elimination, removal, alteration or mitigation of hazards to air navigation, or marking and lighting of obstructions are public purposes for which a political subdivision may raise and expend public funds and acquire land or interests in land.

It is hereby ordained by Boundary County as follows:

Section 2. Short Title. This Ordinance shall be known and may be cited as the Boundary County Airport Zoning Ordinance.

Section 3. Sponsor, Governing Authority, and Administrator.

  1. As used in this Ordinance, the Owner/Sponsor of the Boundary County Airport is the County of Boundary, State of Idaho.
  2. The Owner/Sponsor hereby designates the Boundary County Commissioners as the Governing Authority for the Boundary County Airport.
  3. The Owner/Sponsor hereby designates the Airport Manager as the Administrator for the Boundary County Airport.

Section 4. Definitions. As used in this Ordinance, unless the context otherwise requires:

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.

Airport Direct Impact Area. The area located within 10,000 feet of an airport runway, excluding lands within the runway protection zone and approach/departure surface.

Airport Elevation. The highest point of an airport's usable runway, measured in feet above mean sea level.

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 this ordinance.

Section 5. Airport Zones.  In order to carry out the provisions of this Ordinance, there are hereby created and established certain zones, which include all of the land lying beneath the approach/departure surfaces, horizontal surfaces and conical surfaces as they apply to the Boundary County Airport. Such zones are shown on the Boundary County Airport Zoning Map consisting of one sheet, prepared by Toothman Orton Engineering Co., as part of the Airport Layout Plan, which is attached to this Ordinance and made a part hereof. An area located in more than one (1) of the following zones is considered to be only in the zone with the more restrictive height limitation. The various zones are hereby established and defined as follows:

  1. Approach Zone – The area under an approach/departure surface.
  2. Transitional Zone – The area under a transitional surface.
  3. Horizontal Zone - The horizontal zone is established by swinging arcs of 10,000 feet radii from the center of each end of the primary surface of each runway and connecting the adjacent arcs by drawing lines tangent to those arcs. The horizontal zone does not include the approach/departure zones.
  4. Conical Zone - The conical zone is established as the area that commences at the periphery of the horizontal zone and extends outward a horizontal distance of 4,000 feet.

Section 6.  Imaginary Surface and Noise Impact Boundary Delineation.  The airport elevation, the airport noise impact boundary, and the location and dimensions of the runway, primary surface, runway protection zone, approach/departure surface, horizontal surface, conical surface and transitional surface shall be delineated for each airport subject to this overlay zone and shall be made part of the Official Zoning Map. All lands, waters and airspace, or portions

thereof, that are located within these boundaries or surfaces shall be

subject to the requirements of this overlay zone.

Section 7. Airport Zone Height Limitations. Except as otherwise provided in this Ordinance, no structure shall be erected, altered, or maintained, and no tree shall be allowed to grow in any zone created by this Ordinance 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:

  1. Instrument Approach Zone - Slopes thirty-four (34) 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.

    5. Section 10. Pre-Existing Non-Conforming Uses.
  7. Regulations Not Retroactive – The regulations prescribed by this Ordinance shall not be construed to require the removal, lowering, or other change or alteration of any structure or tree not conforming to the regulations as of the  effective date of this Ordinance, or otherwise interfere with the continuance of a nonconforming use.  Nothing contained herein shall require any change in the construction, alteration, or intended use of any structure, the construction or alteration of which was begun prior to the effective date of this Ordinance, and is diligently prosecuted.
  8. Marking and Lighting- Notwithstanding the preceding provision of this Section, the owner of any existing nonconforming structure or tree is hereby required to allow the installation, operation, and maintenance thereon of such markers and lights as shall be deemed necessary by the Boundary County Planning and Zoning Administrator, to indicate to the operators of aircraft in the vicinity of the airport the presence of such airport obstructions.

Section 11.  Land Use Compatibility Requirements.  Applications for land use or building permits for properties within the boundaries of this overlay zone shall comply with the requirements of this chapter as provided herein.

  1. General. Notwithstanding any other provisions of this Ordinance, no use may be made of land or water within any zone established by this Ordinance in such a manner as to create electrical interference with navigational signals or radio communication between the airport and aircraft, make it difficult for pilots to distinguish between airport lights and others, result in glare in the eyes of pilots using the airport, impair visibility in the vicinity of the airport, create bird strike hazards, or otherwise in any way endanger or interfere with the landing, takeoff, or maneuvering of aircraft intending to use the airport.
  2. Noise. For any property entirely or partially within 10,000 ft of the runway. A notification that noise levels may exceed 55 db shall be attached to any subdivision or partition approval or other land use approval or building permit.  Such notification shall also be included in the closing documents, to be signed by the purchaser, for any parcel entirely or partially within 10,000 ft of the runway.  Any new construction within this area will be encouraged to have increased sound insulation methods.
  3. Outdoor Lighting. No new or expanded industrial, commercial or recreational use shall project lighting directly onto an existing runway or taxiway or into existing airport approach/departure surfaces except where necessary for safe and convenient air travel. Lighting for these uses shall incorporate shielding in their designs to reflect light away from airport approach/departure surfaces. No use shall imitate airport lighting or impede the ability of pilots to distinguish between airport lighting and other lighting.
  4. Glare. No glare producing material, including but not limited to unpainted metal or reflective glass, shall be used on the exterior of structures located within an approach/departure surface or on nearby lands where glare could impede a pilot's vision.
  5. Industrial Emissions. No new industrial, mining or similar use, or expansion of an existing industrial, mining or similar use, shall, as part of its regular operations, cause emissions of smoke, dust or steam that could obscure visibility within airport approach/departure surfaces, except upon demonstration, supported by substantial evidence, that mitigation measures imposed as approval conditions will reduce the potential for safety risk or incompatibility with airport operations to an insignificant level. The review authority shall impose such conditions as necessary to ensure that the use does not obscure visibility.
  6. Existing Communications Facilities and Electrical Interference. No use shall cause or create electrical interference with navigational signals or radio communications between an airport and aircraft. Proposals for the location of new or expanded radio, radiotelephone, and television transmission facilities and electrical transmission lines within this overlay zone shall be coordinated with the Idaho Division of Aeronautics and the FAA prior to approval. Approval of cellular and other telephone or radio communication towers on leased property located within airport surfaces shall be conditioned to require their removal within 90 days following the expiration of the lease agreement. A bond or other security shall be required to insure this result.
  7. Use Prohibitions in RPZ. Notwithstanding the underlying zoning, the following uses are prohibited in the RPZ.
    1. New residential development.
    2. Public assembly facilities.
  8. Landfills. No new sanitary landfills, sewage lagoons, sewage sludge disposal facilities or similar facilities shall be permitted within 10,000 feet of the runway. Expansions of existing landfill or sewage treatment or disposal facilities within these distances shall be permitted only upon demonstration that the landfills are designed and will operate so as not to increase the likelihood of bird/aircraft collisions. Timely notice of any proposed expansion shall be provided to the airport sponsor, Idaho Division of Aeronautics and the FAA, and any approval shall be accompanied by such conditions as are necessary to ensure that an increase in bird/aircraft collisions is not likely to result.

  Notes:

  1. No Structures shall be allowed within the Runway Protection Zone (RPZ). Exceptions shall be made only for structures accessory to airport operations whose location within the RPZ has been approved by the Federal Aviation Administration.
  2. In the RPZ, public airport uses are restricted to those uses and facilities that require location in the RPZ.
  3. Farming practices that minimize wildlife attractants are encouraged.
  4. Roads and parking areas are permitted in the RPZ only upon demonstration that there are not practicable alternatives. Lights, guardrails, and related accessory structures are prohibited. Cost may be considered in determining whether practicable alternatives exist.
  5. In the RPZ, utilities, powerlines and pipelines must be underground. In approach zone and in airport direct and secondary impact areas, the proposed height of utilities shall be coordinated with the airport sponsor and Idaho Division of Aeronautics.
  6. Public assembly facilities are prohibited in the RPZ.
  7. Golf courses may be permitted only upon demonstration, supported by substantial evidence, that management techniques will be utilized to reduce existing wildlife attractants and avoid the recreation of new wildlife attractant. Such techniques shall be required as conditions of the approval. Structures are not permitted within the RPZ. For purposes of this document, tee markers, tee signs, pin cups and pins are not considered to be structures.
  8. Within 10,000 feet from the end of the primary surface of the runway.
  9. Public assembly facilities may be allowed in an approach zone only if the potential danger to public safety is minimal. In determining whether a proposed use is appropriate, consideration shall be given to: proximity to the RPZ; density of people per acre; frequency of use; level of activity at the airport,; and other factors relevant to public safety. In general, high density uses should not be permitted within an airport approach zone, and on residential structures should be located outside approach zones unless no practicable alternatives exist.
  10. Residential densities within approach zones should not exceed the following densities: (1) within 500 feet of the outer edge of the RPZ, 1 unit per acre; (2) within 500 to 1,500 feet of the outer edge of the RPZ, 2 units per acre; (3) within 1,500 to 3,000 feet of the outer edge of the RPZ, 4 units per acre.
  11. Mining operations involving the creation or expansion of water impoundments shall comply with the requirements of this document regarding water impoundments.
  12. Water impoundments are prohibited within 5,000 feet from the edge or end of a runway.
  13. Wetland Mitigation required for projects located within an approach/departure surface, the airport direct or secondary impact area shall be authorized only upon demonstration, supported by substantial evidence, that it is impracticable to provide mitigation outside of these areas.
  14. Within the transitional zone, residential uses and athletic fields are not permitted.
  15. Within the transitional zone, overnight accommodations, such as hotels, motels, hospitals and dormitories, are not permitted.

Section 12.  Water Impoundments within Approach/departure surfaces and Airport Direct and Secondary Impact Boundaries.

  1. No new or expanded water impoundments of one-quarter acre in size or larger are permitted:
    1. Within an approach/departure surface and within 5,000 feet from the end of a runway; or
    2. On land owned by the airport sponsor that is necessary for airport operations.

Section 13. Permits.  An applicant seeking a land use or limited land use approval in an area within this overlay zone shall provide the following information in addition to any other information required in the permit application:

  1. A map or drawing showing the location of the property in relation to the airport imaginary surfaces. The Planning Department shall provide the applicant with appropriate base maps upon which to locate the property.
  2. Elevation profiles and a site plan, both drawn to scale, including the location and height of all existing and proposed structures, measured in feet above mean sea level.
  3. If a height variance is requested, letters of support from the airport sponsor, the Idaho Division of Aeronautics and the FAA.
    1. Future Uses - Except as specifically provided below, no material change shall be made in the use of land, no structure shall be erected or otherwise established, and no tree shall be planted in any zone hereby created unless a permit therefore shall have been applied for and granted. Each application for a permit shall indicate the purpose for which the permit is desired, with sufficient particularity to permit it to be determined whether the resulting use, structure, or tree would conform to the regulations herein prescribed. If such determination is in the affirmative, the permit shall be granted. No permit for a use inconsistent with the provisions of this Ordinance shall be granted unless a variance has been approved in accordance with Section 13- 4.
    2. In the area lying within the limits of the horizontal zone and conical zone, no permit shall be required for any tree or structure less than seventy-five feet of vertical height above the ground, except when, because of terrain, land contour, or topographic features, such tree or structure would extend above the height limits prescribed for such zones. Nothing contained in the foregoing exceptions shall be construed as permitting or intending to permit any construction, or alteration of any structure, or growth of any tree in excess of any of the height limits established by this Ordinance except as set forth in Section 7-D.
    3. Existing Uses - No permit shall be granted that would allow the establishment or creation of an obstruction or permit a nonconforming use, structure, or tree to become a greater hazard to air navigation than it was on the effective date of this Ordinance or any amendments thereto or than it is when the application for a permit is made. Except as indicated, all applications for such a permit shall be granted.
    4. Nonconforming Uses Abandoned or Destroyed - Whenever the Boundary County Planning and Zoning Administrator determines that a nonconforming tree or structure has been abandoned or more than 80 percent torn down, physically deteriorated, or decayed, no permit shall be granted that would allow such structure or tree to exceed the applicable height limit or otherwise deviate from the zoning regulations.
    5. Variances - Any person desiring to erect or increase the height of any structure, or permit the growth of any tree, or use property, not in accordance with the regulations prescribed in this Ordinance, may apply to the Boundary County Planning and Zoning Administrator for a variance from such regulations. The application for variance shall be accompanied by a determination from the Federal Aviation Administration and the Idaho Division of Aeronautics as to the effect of the proposal on the operation of air navigation facilities and the safe, efficient use of navigable airspace. Such variances shall be allowed where it is duly found that a literal application or enforcement of the regulations will result in unnecessary hardship and relief granted, will not be contrary to the public interest, will not create a hazard to air navigation, will do substantial justice, and will be in accordance with the spirit of this Ordinance. Additionally, no application for variance to the requirements of this Ordinance may be considered by the Board of County Commissioners unless a copy of the application has been furnished to the Airport Manager for advice as to the aeronautical effects of the variance. If the Airport Manager does not respond to the application within 15 days after receipt, the Board of County Commissioners may act on its own to grant or deny said application.

If deemed proper by the Board of County Commissioners, this condition may be modified to require the owner to permit the Idaho Transportation Department, Division of Aeronautics, at its own expense, to install, operate, and maintain the necessary markings and lights.
