These layers include parts of the Airspace Overlay District described in City of Lawrence's (Kansas) Land Development Code Section 20-302.
We obtained these layers from the City of Lawrence in November, 2023 as a shapefile and converted it to a feature class for use in this web application.
These layers are static and may not be updated regularly. The last update of this layer was on November 29, 2023.
All data, information, and maps are provided "as is" without warranty or any representation of accuracy, timeliness of completeness. The burden for determining accuracy, completeness, timeliness, merchantability and fitness for or the appropriateness for use rests solely on the requester.

20-302 (a) Purpose "The Airspace Overlay District is intended to (1) prevent the creation and establishment of hazards to life and property in the vicinity of any Airport owned, controlled or operated by the City of Lawrence; (2) protect users of the Airport and; (3) prevent any unreasonable limitation or impairment on the use and expansion of the Airport and the public investment therein."
20-302 (e) Sub-Zones Established (1) Instrument Approach Zone: "The Instrument Approach Zone is established at each end of all runways used for instrument landings and takeoffs. The Instrument Approach Zones have a width of 1,000 feet at a distance of 200 feet beyond the end of each instrument 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."
20-302 (e) Sub-Zones Established (2) Non-Instrument Approach Zone: "The Non-Instrument Approach Zone is established at each end of all runways used for non-instrument landings and takeoffs. The Non-Instrument Approach Zone has a width of 500 feet at a distance of 200 feet beyond the end of each non-instrument runway, widening thereafter uniformly to a width of 2,500 feet at a distance of 10,200 feet beyond each end of the runway, its centerline being the continuation of the centerline of the runway."
20-302 (e) Sub-Zones Established (3) Transition Zone: "The Transition Zone is established adjacent to each instrument and noninstrument runway and approach zone as indicated on the Official Zoning District Map. Transition Zones symmetrically located on either side of runways have variable widths as shown on the Official Zoning District Map. Transition Zones extend outward from a line of 250 feet on either side of the centerline of a non-instrument runway for the length of such runway plus 200 feet on each end; and 500 feet on either side of the centerline of an 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 (1) foot vertically for each seven (7) 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 these Approach Zones. These Transition Zones have variable widths, as shown on the Official Zoning District Map. Such 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 (1) foot vertically for each seven (7) 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 Zone, 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."
20-302 (e) Sub-Zones Established (4) Horizontal Zone: "A Horizontal Zone is that area within a circle with its center at the Airport Reference Point and having a radius of 7,000 feet. The Horizontal Zone does not include the Instrument and Non-Instrument Approach Zones or the Transition Zones."
20-302 (e) Sub-Zones Established (5) Conical Zone: "A Conical Zone is the area that commences at the periphery of the Horizontal Zone and extends outward a distance of 5,000 feet. The Conical Zone does not include the Instrument Approach Zone and Transition Zones."
20-302 (f) Height Limitations (1) 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."
20-302 (f) Height Limitations (3) Transition Zone: "One (1) foot in Height for each seven (7) feet in horizontal distance beginning at any point 125 feet normal to and at the elevation of the centerline of noninstrument 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 Airport elevation. In addition to the foregoing there are established Height limits of one (1) foot vertical Height for each seven (7) 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 Instrument Approach Zone projects through and beyond the Conical Zone, a Height limit of one (1) foot for each seven (7) 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."
20-302 (f) Height Limitations (5) Conical Zone: "One (1) foot in Height for each 20 feet in horizontal distance beginning at the periphery of the Horizontal Zone, extending to a Height of 400 feet above the Airport elevation."
