In the Commercial Airport Safety overlay zone, the following limitations and standards apply to all uses permitted outright or conditionally in the base zone to which the overlay is applied:
(1) Operational Interference. No use shall:
(a) Create electrical interference with the navigational signals or radio communication between the airport and aircraft;
(b) Make it difficult for pilots to distinguish between airport lights and others;
(c) Result in glare in the eyes of pilots using the airport;
(d) Impair visibility in the vicinity of the airport;
(e) Create bird strike hazards, or
(f) In any way otherwise endanger or interfere with the landing, take-off, or maneuvering of aircraft intending to use the airport.
(2) Marking and Lighting. The owner of any existing structure, object, or vegetation that does not conform to the height limits of this overlay zone shall be required to permit the installation, operation, and maintenance thereon of markers and lights as deemed necessary by the city to indicate to aircraft operators in the vicinity of the airport the presence of those aircraft instructions. The markers and lights shall be installed, operated and maintained at the city’s expense.
(3) Height. The maximum height of structures and objects shall normally be the same as the zones to which the commercial airport safety overlay zone is added. However, no structure shall be erected, altered, or maintained, and no vegetation shall be allowed to penetrate the surface heights of the various sectors as described below and shown on the Airspace plan. These sectors include all land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces, and conical surfaces as they apply to the Eugene Airport. An area located in more than one sector is considered to be only in the sector with the most restrictive height limit. For purposes of this overlay zone, to determine height limits, the datum is mean sea level elevation unless otherwise specified.
Runways 16L-34R and 16R-34L Approach Sectors. Runway 16R-34L is an existing, precision instrument runway. Runway 16L-34R is a future precision instrument runway. The inner edge of both of their approach sectors coincide with the width of the runway primary surfaces and are 1000 feet wide. The approach sectors expand outward uniformly to a width of 16,000 feet at a horizontal distance of 50,000 feet from the primary surfaces. Their centerlines are a continuation of the runway centerlines beginning at the centerpoint coordinates. The surfaces of the Runway 16L-34R and Runway 16R-34L approach sectors slope 50 feet outward for each 1 foot upward beginning at the end of and at the same elevation as the primary surfaces and extend to a horizontal distance of 10,000 feet along the extended runway centerlines; thence slope upward 40 feet horizontally for each 1 foot vertically to an additional horizontal distance of 40,000 feet along the extended runway centerlines.
Horizontal Sector. The horizontal sector encompasses the area obtained 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. However, the horizontal sector does not include the approach and transition sectors. The surface of the horizontal sector is a horizontal plane that is 515 feet above mean sea level. That is 150 feet above the airport elevation.
Conical Surface. The surface of the conical sector extends at a slope of 20 feet outward for each foot upward from the periphery of a horizontal surface for a horizontal distance of 4,000 feet. It begins 150 feet above the airport’s elevation and extends to a height of 350 feet above the airport’s elevation.
