The Airport Influence District will require certain special limitations on land use as follows:
A. Height Limitations: Height limitations within the Airport Influence Area District, except as otherwise provided in this article, are subject to the recommendations of the City which may consult with other appropriate agencies to develop such recommendations. Except as may otherwise be allowed in this article, no structure or object of natural growth shall be constructed, erected, altered, allowed to grow, or to be maintained in excess of height limits and airport related zones herein established.
B. Notice Of Proposed Construction And Alteration Form: Submission of a notice of proposed construction and alteration (FAA form 7460-1) and subsequent approval from the Federal Aviation Administrator shall be required for the City to issue a permit for the construction or alteration of any structure penetrating a 100:1 foot plane located within twenty thousand feet (20,000') from any runway, except as allowed in section 10-12A-7 of this article. Receipt of FAA form 7640-9, Determination of No Hazard for any structure, is required before issuing a building permit, unless the foregoing plane is not penetrated or the foregoing heights are complied with.
C. FAR Part 77 Imaginary Surface Limitations: Imaginary surface limitations as prescribed by Federal Aviation Regulation Part 77, within the Airport Influence Area Overlay District include all land and air space within the area which would be hazardous to air navigation. These limitations represent areas above imaginary surfaces and are designed to regulate the height of structures and trees in the airport vicinity. They are set forth by the FAA in the Federal Aviation Regulations Part 77. All of the surface limitation categories listed below have their dimensions given in the FAA approved Fillmore Municipal Airport Layout Plan adopted and dated March 2006.
1. Runway Protection Zone: A runway protection zone (RPZ) is trapezoidal in shape and centered about the extended runway centerline. The RPZ is the land at ground level that begins two hundred feet (200') beyond the end of each runway.
2. Object Free Area: The object free area (OFA) is a two- dimensional ground area surrounding runways, taxiways and taxi lanes, which is clear of all objects except those whose location is fixed by function and excepted by the FAA.
3. Runway Safety Area: A defined surface area surrounding the runway prepared or suitable for reducing the risk of damage to airplanes.
4. Primary Surface: A Part 77 airport surface longitudinally centered on a runway. The primary surface extends two hundred feet (200') beyond the paved surface end.
5. Approach Surface: A surface longitudinally centered on the extended runway centerline and extending outward and upward from each end of the primary surface. An approach surface is applied to each end of each runway based upon the type of approach available or planned for that runway end. Refer to the Fillmore Municipal Airport Layout Plan (ALP) drawings for the airport to determine the approach surfaces and slopes.
6. Transitional Surfaces: The transitional surfaces are located on both sides of the approach and primary surfaces. These surfaces extend outward and upward at right angles to the runway centerline and runway centerline extended, at a slope of seven feet (7') horizontal for every one foot (1') vertical rise from the sides of the primary and approach surfaces, until it reaches one hundred fifty feet (150') above the highest point on any runway (airport elevations).
7. Horizontal And Conical Surfaces: These are the upper aeronautical surfaces surrounding an airport that are used by aircraft for turning and maneuvering in close proximity to the airport preceding landing and immediately after takeoff.
D. Land Use Limitations: To assume the protection of the public from overflight impacts and hazards associated with flying operations, and to comply with FAR Part 77, all uses shall be evaluated by the City and approved according to the conditions of this article.
1. Special Criteria Areas (Zones) Within The District:
a. Horizontal And Conical Surfaces Zone: Exposure to airport overflight is considered minimal, but increases as the runway ends are approached. Residential construction should be limited to low density development. The siting of public facilities, such as hospitals, schools, churches, etc., or noise sensitive development near runway approaches, should be discouraged.
b. Approach Surface Zone: Exposure to airport noise is considered moderate. Residential and public facilities should be carefully reviewed in this zone for compatibility with airport operations. Residential and public facilities that are not compatible with airport operations shall be prohibited in the approach surface zone. Nonresidential development should be restricted as to density and should only be approved provided noise attenuation measures are incorporated into facility design. Aviation easements are recommended for all new buildings and developments and fair disclosure notices shall be filed with each new building or development.
c. Runway Protection Zone: All land in this zone should be kept clear of any structures. Land use in this area should be restricted to open space or agriculture.
(1) Areas two thousand feet (2,000') wide extending five thousand feet (5,000') horizontally from a point two hundred feet (200') from each end of visual runways.
(2) Areas four thousand feet (4,000') wide extending ten thousand feet (10,000') horizontally from a point two hundred feet (200') from each end of instrument runways.
Due to overlapping concerns of the above zones, the critical zones require that no use may be made or activity carried on land within this zone in a manner as to:
(1) Create electrical interference with navigational signals or radio communication between the airport and aircraft;
(2) Make it difficult for pilots to distinguish between airport lights and other lighting;
(3) Result in glare in the eyes of pilots using the airport;
(4) Impair visibility in the vicinity of the airport; or
(5) Otherwise in any way create a hazard or endanger the landing, takeoff or maneuvering of aircraft intending to use the airport.
2. Fair Disclosure Statement: Fair disclosure statements serve to notify prospective buyers of property near airports that they may be exposed to potentially impactive levels of aircraft overflight. These statements in no way abrogate an individual's right to take later action against the airport, but they at least give buyers a fair warning. These statements may also limit the height of natural growth to the height specified therein.
3. Aviation Easement: An aviation easement is a nonpossessory property interest in airspace over a land parcel or portion of land. It is a legally developed document obtained by an airport to cover items such as the right of flight, right to remove obstructions, etc., but not necessarily to the extent of prohibiting the use of land within the limits of the rights obtained.
