§ 25-43. Height of structures.

(a)

Apartment houses or public or semipublic buildings. In any district, apartment houses or public or semipublic buildings, such as hospitals, hotels, churches, sanitariums or schools, either public or private, where permitted, may be erected to a height not to exceed one hundred fifty (150) feet; provided, that such buildings shall have yards the depth or width of which shall be increased one (1) foot on all sides for each additional foot that such buildings exceed the specified height limit as established by the regulations of the district in which such buildings are situated.

(b)

Dwellings in R-1 or R-2 districts. Dwellings in districts R-1, R-2 or R-2-S may be increased in height not exceeding ten (10) feet in addition to the limitations of two and one-half (2½) stories, or thirty-five (35) feet, as prescribed in such districts; provided, that two (2) side yards of not less than fifteen (15) feet in width each are provided. In no case shall such dwelling exceed three (3) stories in height.

(c)

Parapet walls, flagpoles, chimneys, etc. Parapet walls and false mansards shall not extend more than six (6) feet above the height limit. Flagpoles, chimneys, cooling towers, electric display signs, elevator bulkheads, penthouses, finials, gas tanks, grain elevators, stacks, storage towers, radio towers, ornamental towers, monuments, cupolas, domes, spires, standpipes and necessary mechanical appurtenances may be erected as to height in accordance with present or future provisions of this Code or other ordinances of the city.

(d)

Through lots. On through lots one hundred twenty-five (125) feet or less in depth, the height of a building may be measured from the curb level of either street. On through lots of more than one hundred twenty-five (125) feet in depth, the height regulations for the street permitting the greater height shall apply to a depth of not more than one hundred twenty-five (125) feet from that street.

(e)

Areas near airports. In the vicinity of an airport no building or structure shall be erected in any area under any approach or transition plane or turning zone, as defined hereafter, any portion of which building or structure intrudes into such plane or zone; except, that this shall not prohibit the erection of buildings or structures to a total height of not over thirty-five (35) feet. No land shall be used in any area under an approach or transition plane within ten thousand (10,000) feet of the reference point of the airport for the erection of places of public assembly or concentration of population, such as churches, schools, theaters or hospitals.

An approach plane is an area commencing at a line of two hundred (200) feet from the end of an active runway on an airport. From this point the approach plane rises upward on a plane surface at the ratio of one (1) foot vertical rise for every fifty (50) feet of horizontal distance. This plane is bounded by lines commencing at the two-hundred-foot mark previously mentioned five hundred (500) feet on each side of the continuation of the centerline of the runway mentioned above, and these lines continue along such plane gradually extending outward, so that at a distance of ten thousand (10,000) feet the lines are two thousand (2,000) feet distant on each side of the extended centerline of the runway; and at fifty thousand (50,000) feet, they are extended to a point eight thousand (8,000) feet distant on each side of the extended centerline of the runway.

A transition plane begins at the flared sides of the approach plane on a slope outward of one (1) foot in height for each seven (7) feet of horizontal distance.

A turning zone is a plane of one hundred fifty (150) feet above the designated reference point on the landable area and extending in all directions to a distance of twenty thousand (20,000) feet from this reference point. Landable area is the area of the airport used for the landing, takeoff or taxiing of aircraft.

No limitations on height shall be required beyond the limits of twenty thousand (20,000) feet from the designated reference point, except within the approach and transition planes.
