Land use regulations are:
A. Permitted Uses.
1. Any use permitted in the underlying zoning district except:
a. Uses creating electrical or electronic interference with communication or guidance devices used by aircraft or ground control;
b. Uses creating glare, smoke, dust or similar factors interfering with aircraft operation to and from the runways or on the runways and taxiways of the airport;
c. Uses requiring buildings or structures located otherwise or grown or constructed in excess of the height limits herein (below) specified. (Ord. 525 § 1(part), 1989).

(See also Sections 18.98.010--18.98.090.)
No residential structure may be located within one hundred feet of the projected centerline of any instrumented runway for a distance of one mile from each end of the corresponding runway. (Ord. 525 § 1(part), 1989).

(See also Sections 18.98.100--18.98.130.)
A. Building, Structure, or Tree Height Limited. No structure or tree shall be erected, altered, allowed to grow, or maintained in any space created in this AAO district. Dimensions are established for each of the spaces. The following spaces constitute the parts of the AAO, airport/airspace overlayed district:
1. Instrument Approach Space. A volume of space above geometric planes one foot in height for each fifty feet in horizontal distance beginning at a line two hundred feet from, and at the elevation of each end of the instrument runway and extending to a distance of ten thousand two hundred feet from each end of that runway; thence one foot in height for each forty feet in horizontal distance to a line fifty thousand two hundred feet from each end of that runway. The geometric planes are one thousand feet wide at the end nearest the runway and widen symmetrically to sixteen thousand feet at the farthest end.
2. Noninstrument Approach Space. A volume of space above one foot in height for each twenty feet in horizontal distance beginning at a line two hundred feet from, and at the elevation of, each end of the noninstrument runway and extending to a line ten thousand two hundred feet from each end of that runway. The geometric planes are five hundred feet wide and centered on the extended centerline of the runway at the end nearest the runway and widen symmetrically to two thousand five hundred feet at the farthest end.
3. Transition Spaces. A volume of space above geometric planes one foot in height for each seven feet in horizontal distance beginning at a line two hundred fifty feet from, parallel to, and at the elevation of, the centerline of noninstrument runways, extending two hundred feet beyond each end thereof; and five hundred feet from and parallel to, and at the elevation of the centerline of, the instrument runway, extending two hundred feet beyond each end thereof, and extending to a height of one hundred fifty feet above the airport elevation. Such geometric planes continue outward and upward to an intersection with the base geometric plane of the horizontal space.
In addition to the foregoing, this volume of space includes the space above the geometric planes one foot in height for each seven feet in horizontal distance, measured from the sides of all approach spaces for the entire length of the approach spaces and extending upward and outward to the lines where they intersect the horizontal or conical space geometric planes. Further, the volume of space includes the space above the projection of the geometric planes defining the instrument approach space through and beyond the plane defining the conical space and further, above one foot for each seven feet of horizontal distance beginning at the sides of the instrument approach space and extending a horizontal distance of five thousand feet from the side of the instrument approach space.
4. Horizontal Space. A volume of space above a circular geometric plane one hundred and fifty feet above the airport elevation, centered on the airport reference point and twenty thousand feet in diameter.
5. Conical Space. A volume of space above an inverted truncated conical geometric surface one foot in height for each twenty feet in horizontal distance beginning at the periphery of the geometric plane defining the horizontal space and extending upward and outward to a horizontal distance of fifteen thousand feet from the airport reference point.
B. Where an area is overlayed by more than one defined space, the more restrictive limitation shall prevail. Otherwise, maximum permitted structure heights corresponding to the requirements of the underlying zoning district shall be required. (Ord. 525 § 1(part), 1989).

(See also Section 18.100.010.)
Lot dimensions corresponding to the requirements of the underlying zoning district shall be required. (Ord. 525 § 1(part), 1989).

(See also Chapter 18.102.)
Off-street parking area requirements corresponding to the requirements of the underlying zoning district shall be required. (Ord. 525 § 1(part), 1989).
