Article 5: Uses Section 5.17: Standards for Miscellaneous Uses Orange County, North Carolina – Unified Development Ordinance Page 5-137 (a)(d) The site plan shall containe Aa configuration diagram depicting the layout of runways, taxiways, approach zonesAirport Surface Zones, helicopter pads, and overrun areas. These diagrams should also be on aerial photographs that show the area within five 27 miles of the proposed site. (b)(e) Isotonic contours or noise contour lines 8showing the effects of aircraft operations upon land within one mile of the boundary of the proposed site. (c)(f) The number and type of aircraft proposed to be stored including also the storage areas for aircraft, fuel and motor vehicles, service areas for aircraft.9 (d)(g) How on site fire and rescue services shall be provided and a letter from the appropriate agency stating services are available and adequate to protect the proposed facility. (e)(h) List of land uses located within the final approach zones of the airportairfield. (i) Hazardous Materials Management Plan, including a description of the program for application, storage, and handling of various chemicals and fuel products including, but not limited to, the following: (i) Airplane fuel, (ii) Hydrolic fluid, (iii) Oil, (iv) Lubricants utilized to support aircraft, (v) Pesticides and/or fertilizers, and (vi) Any other hazardous substances; A Material Safety Data Sheet listing each substance, its known impacts, physical properties, and protective measures is required as part of the submittal. (f)(j) Certification that all Federal Aviation Administration (FAA) and State standards and requirements have been met. (2) Standards of Evaluation (a) There shall be a limit of 5 aircraft for the facility all of which shall be owned by the property owner.10 (a)(b) All F.A.A. and State regulations are met as a condition of approval including, but not limited to, noise level limits.11 7 Staff is not requiring the full 5 mile radius for an Airport‐Private Airfield as the impacts should not be as great as what we anticipate for an Airport – General Aviation land use. 8 In reviewing FAA information on airport development these terms are used interchangeably. 9 This provision was moved to subsection(s) (b) and (c) of the proposed amendment. 10 Staff is recommending this language to avoid the blurring of commercial versus private facilities. What we want to avoid is a private property owner allowing for ‘public’ use of an airstrip as part of a club, organization, or other similar activity. 11 Noise contour lines are a continuous line on a map representing equal levels of noise exposure. According to the FAA severe noise exposure occurs outside the 55 DNL (day‐night average sound level) contour line, the level at which the Federal Aviation Administration (FAA) describes noise exposure as minimal. Noise exposure is regarded as significant above the 65 DNL noise contour line. 63
