§ 17.34.020. Height limits.
Except as otherwise provided in this title, no structure or tree shall be erected, altered, allowed to grow, or be maintained in any zone created by this title to a height in excess of the applicable height limit established in this section for such zone. Such applicable height limitations are established for each of the zones in question as follows:
A.
Utility Runway Visual Approach Zone. Slopes upward twenty feet horizontally for each foot vertically, beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of five thousand feet along the extended runway centerline.
B.
Utility Runway Nonprecision Instrument Approach Zone. Slopes upward twenty feet horizontally for each foot vertically beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of five thousand feet along the extended runway centerline.
C.
Runway Larger Than Utility Visual Approach Zone. Slopes upward twenty feet horizontally for each foot vertically beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of five thousand feet along the extended runway centerline.
D.
Precision Instrument Runway Approach Zone. Slopes upward fifty feet horizontally for each foot vertically beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of ten thousand feet along the extended centerline; thence slopes upward forty feet horizontally for each foot vertically to an additional horizontal distance of forty thousand feet along the extended runway centerline.
E.
Transitional Zones. Slopes upward and outward seven feet horizontally for each foot vertically beginning at the side of and at the same elevation as the primary surfaces and the approach zones, and extending to a height of one hundred fifty feet above the airport elevation, which airport elevation is five thousand five hundred fifty-three feet above mean sea level. In addition to the foregoing, there are established height limits sloping upward and outward seven feet horizontally for each foot vertically beginning at the sides of and at the same elevation as the approach zones, and extending to where they intersect the conical surface. Where the precision instrument runway approach zone projects beyond the conical zone, height limits sloping upward and outward seven feet horizontally for each foot vertically shall be maintained beginning at the sides of and at the same elevation as precision instrument runway approach surface, and extending to a horizontal distance of five thousand feet measured at ninety-degree angles to the extended runway centerline.
F.
Horizontal Zone. One hundred and fifty feet above the airport elevations or a height of five thousand seven hundred three feet above mean sea level.
G.
Conical Zone. Slopes upward and outward twenty feet horizontally for each foot vertically beginning at the periphery of the horizontal zone and at one hundred and fifty feet above the airport elevation and extending to a height of three hundred and fifty feet above the airport elevation.
H.
Excepted Height Limitations. Nothing in this title shall be construed as prohibiting the growth, construction, or maintenance of any tree or structure to a height of up to fifty feet above the surface of the land, except in approach zones within two thousand five hundred feet of the ends of the primary surfaces.
Where an area is covered by more than one height limitation, the more restrictive limitation shall prevail.
