Junction City City Zoning Code

The creation or establishment of an airport hazard is a public nuisance and an injury to the region served;

It is necessary in the interest of the public health, public safety and general welfare that the creation or establishment of airport hazards be prevented, and;

The prevention of these hazards should be accomplished, to the extent legally possible, by the exercise of the police power without compensation. It is further declared that both the prevention of the creation or establishment of airport hazards and the elimination, removal, alteration, mitigation, or marking and lighting of existing airport hazards are public purposes for which the City of Junction City may raise and expend public funds and acquire land or interests in land.

Precision Instrument Approach Zone. A precision instrument approach zone is established at each end of the precision instrument runway utilizing an Instrument Landing System (ILS) for precision instrument landings and takeoffs. The precision instrument approach zones shall have a width of 1,000 feet at a distance of 200 feet beyond each end of the runway, widening thereafter uniformly to a width of 16,000 feet at a distance of 50,200 feet beyond each end of the runway, its centerline being the continuation of the centerline of the runway.

Non-Precision Instrument Approach Zone. A non-precision instrument approach zone is established at each end of all non-precision instrument runways for non-precision instrument landings and takeoffs. The non-precision instrument approach zone shall have a width of 500 feet at a distance of 200 feet beyond each end of the runway, widening thereafter uniformly to a width of 2,000 feet at a distance of 5,200 feet beyond each end of the runway, its centerline being the continuation of the centerline of the runway.

Visual Approach Zone. A visual flight rules approach zone shall have a width of 250 feet at a distance of 200 feet beyond each end of the runway widening thereafter uniformly to a width of 1,250 feet at a distance of 5,200 feet beyond each end of the runway.

Transition Zones. Transition zones are hereby established adjacent to each precision instrument, non-precision instrument, and visual runway and approach zone as indicated on the zoning map. Transition zones symmetrically located on either side of runways have variable widths as shown on the zoning map. Transition zones extend outward from a line 125 feet on either side of the centerline of the visual runway, for the length of such runway plus 200 feet on each end; 250 feet either side of the centerline of the non-precision instrument runway, for the length of such runway plus 200 feet on each end; and 500 feet on either side of the centerline of the precision instrument runway, for the length of such runway plus 200 feet on each end, and are parallel and level with such runway centerlines. The transition zones along such runways slope upward and outward one foot vertically for each seven feet horizontally to the point where they intersect the surface of the horizontal zone. Further, transition zones are established adjacent to both instrument and non-instrument approach zones for the entire length of the approach zones. These transition zones flare symmetrically with either side of the runway approach zones from the base of such zones and slope upward and outward at the rate of one foot vertically for each seven feet horizontally to the points where they intersect the surfaces of the horizontal and conical zones. Additionally, transition zones are established adjacent to the instrument approach zone where it projects through and beyond the limits of the conical zones, extending a distance of 5,000 feet measured horizontally from the edge of the instrument approach zones at right angles to the continuation of the centerline of the runway.

Horizontal Zone. A horizontal zone is established by swinging arcs of 5,000 feet radii for all runways designated utility or visual and 10,000 feet for all other runways 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. The horizontal zone does not include the approach zones and the transition zones.

Conical Zone. A conical zone is hereby established as the area that commences at the periphery of the horizontal zone and extends outward and upward at a slope of 20 to one for a distance of 4,000 feet.

Precision Instrument Approach Zone. One foot in height for each 50 feet in horizontal distance beginning at a point 200 feet from and at the centerline elevation of the end of the instrument runway and extending to a distance of 10,200 feet from the end of the runway; thence one foot in height for each 40 feet in horizontal distance to a point 50,200 feet from the end of the runway.

Non-Precision Instrument Approach Zones. One foot in height for each 20 feet in horizontal distance beginning at a point 200 feet from and at the centerline elevation of the end of the non-precision instrument runway and extending to a point 10,200 feet from the end of the runway.

Visual Airport Approach Zones. One foot in height for each 20 feet in horizontal distance beginning at a point 200 feet from and at the centerline elevation of the end of the runway and extending to a point 5,200 feet from the end of the runway.

Transition Zones. One foot in height for each seven feet in horizontal distance beginning at any point 125 feet normal to and at the elevation of the centerline of visual runways, extending 200 feet beyond each end thereof; 250 feet normal to and at the elevation of the centerline of the non-precision instrument runways, extending 200 feet beyond each end thereof; and 500 feet normal to and at the elevation of the centerline of the instrument runway, extending 200 feet beyond each end thereof, extending to a height of 150 feet above the established airport reference elevation. In addition to the foregoing, there are established height limits of one foot vertical height for each seven feet horizontal distance measured from the edges of all approach zones for the entire length of the approach zones and extending upward and outward to the points where they intersect the horizontal or conical surfaces. Further, where the precision instrument approach zone projects through and beyond the conical zone, a height limit of one foot for each seven feet of horizontal distance shall be maintained beginning at the edge of the instrument approach zone and extending a distance of 5,000 feet from the edge of the instrument approach zone measured normal to the centerline of the runway extended.

Horizontal Zones. 150 feet above the airport elevation.

Conical Zone. One foot in height for each 20 feet of horizontal distance beginning at the periphery of the horizontal zone and at 150 feet above the airport elevation, extending to a height of 350 feet above the airport elevation.

Excepted Height Limitations. Nothing in this Chapter shall be construed as prohibiting the growth, construction or maintenance of any tree or structure to a height up to 50 feet above the surface of the land. However, where an area is covered by more than one height limitation, the more restrictive limitation shall prevail.

In the area lying within the limits of the horizontal zone and the conical zone, any tree or structure less than 75 feet of vertical height above the ground may be planted, erected, altered or otherwise established, except when because of terrain, land contour or topographic features such tree or structure would extend above the height limits prescribed for such zone or would be in conflict with the height limitations for the various zoning districts as established in Chapter 405 of this Title.

In the areas lying within the limits of the approach zones but at a horizontal distance of not less than 4,200 feet from each end of the runways, any tree or structure less than 75 feet of vertical height above the ground may be planted, erected or altered or established, except when such tree or structure would extend above the height limit prescribed for such approach zones, or would be in conflict with the height limitations of the various zoning districts as established in Chapter 405 of this Title.

In the areas lying within the limits of the transition zones beyond the perimeter of the horizontal zone, any tree or structure less than 75 feet of vertical height above the ground may be planted, erected, altered or established, except when such tree or structure, because of terrain, land contour or topographic features would extend above the height limit prescribed for such transition zones, or would be in conflict with the height limitations for the various zoning districts as established in Chapter 405 of this Title.
