(A) Heliports (see § 157.010). Dimensional requirements for this use shall be a minimum site of five acres. Setbacks from helicopter pads shall be at least 100 feet for each helicopter operating from the facility, up to a maximum setback of 400 feet.
(B) Private landing strips. Dimensional requirements for this use shall be a minimum of ten acres.
(1) An area equal to 15% of the runway length shall be within the site at both ends of the runway.
(2) The setback from the runway shall be a minimum of 100 feet for each aircraft operating from the facility, up to a maximum of 400 feet.
(3) No dwelling unit shall be within 500 feet of either end of the runway.
(C) General aviation airport. Dimensional requirements for this use shall be 100 acres. Development plans for this classification shall be submitted with a noise impact assessment. Said assessment shall identify the initial 20-year projected day-night level (DNL, see § 157.010) noise contour lines beginning with 50 DNL and proceeding to 75 DNL.
(1) The 20 year, 70 DNL line shall be completely contained within the airport property, or adjacent land that has been granted a noise easement.
(2) If the 55 DNL area expands, a land use plan for all land within the 55 DNL noise contour shall be submitted.
(3) This plan shall indicate the feasibility of restricting such land to non-residential uses.
(4) Airport approval shall be based on the ability to minimize noise intrusion (pollution) to existing residential areas and to prohibit residential development that would limit future airport expansion.
(5) Once established, the county shall require all rezonings that would permit residential use within the 20-year, 55 DNL noise contour to record the noise contours on the property.
(6) All developments and all individual lot surveys would be required to identify (illustrate) the noise contours, to be indicated on the preliminary and final plats as reviewed by the Planning/Zoning and Code Enforcement Department, Planning Board and Board of Commissioners. In addition, to be included on the final recorded plat for the development a warning would accompany all such lots to indicate that the county will not limit future airport expansion due to residential development within the 55 DNL noise contour.
(7) This use (general aviation airport) shall be separated from all residential districts and schools by a minimum of 1,500 feet.
(8) This use shall comply with all applicable requirements for line of sight and regulations from the Department of Homeland Security and Federal Aviation Administration (FAA).
