A. Height Limits Designated: Building height limits are as follows:
1. Two and one-half (21/2) stories or thirty five feet (35') in the SA-1, SA-2, R-1A and R-1B districts.
2. Where a building in a C or M-1 district is adjacent to a lot in an S or R district, it must be set back from such a lot line one foot (1') for each six feet (6') of building height.
3. Eight (8) stories or one hundred feet (100') in the C district; provided, that where a lot in the C district is adjacent to a lot in an R district, the building shall be set back from such a lot line one foot (1') for each six feet (6') of building height; and provided further, that one off street parking space shall be provided on the lot for each one thousand (1,000) square feet of floor space in a building that is in excess of three (3) times the lot area. (1996 Code § 17.36.010)
B. Increase In Height Limits:
1. If a public building, church, temple, hospital, institution or school is set back an additional foot over the yards required in section 9-9-2 of this chapter, it may be increased in height two feet (2') over the height limit of subsection A of this section up to a limit of seventy feet (70').
2. Chimneys, church steeples, cooling towers, elevator bulkheads, fire towers, monuments, stacks, stage towers or scenery lofts, tanks, water towers, ornamental towers, spires, radio and television towers, grain elevators or necessary mechanical appurtenances are exempt from height regulations, but a permit must be obtained from the building inspector/code enforcement officer.
3. Storage buildings are exempt from the story limitations (but not the "number of feet" limitation).
4. Buildings in the C district may be increased in height one foot (1') for each foot that the building is set back from all required yard lines. (1996 Code § 17.36.020)
C. Runway Proximity:
1. No building or structure or any portion thereof shall be erected within the approach zone of any runway or landing strip approved by the federal aviation agency in excess of a height above the elevation at the end of the runway equal to one- fortieth (1/40) of the horizontal distance from the end of the runway, measured along the centerline of the runway extended. The approach zone is considered to be a trapezoidal area extending from the end of, and in the same direction as, the runway for a distance of two (2) miles. Such area is five hundred feet (500') wide at the end of the runway and two thousand five hundred feet (2,500') wide two (2) miles from the end of the runway.
2. Further, no building or structure or any portion thereof shall be erected in the transition zones on either side of an approach zone of any such runway or landing strip in excess of a height above the elevation at the end of the runway, computed as follows:
a. One-fortieth (1/40) of the horizontal distance from the end of the runway, measured along the centerline of the runway extended; plus
b. One-seventh (1/7) of the horizontal distance to the near edge of the approach zone, measured perpendicular to the centerline of the runway extended;
c. Where an airport is bounded by a public road, the effective length of runways directed over any such public road shall be computed (using a slope of 40 feet horizontal to 1 foot vertical) to produce a height of fourteen feet (14') at the right of way line of such road nearest to the airport. (1996 Code § 17.36.030)
D. Alterations To Existing Buildings: Those parts of existing buildings that violate height regulations may be repaired or remodeled, but may not be reconstructed or structurally altered. (1996 Code § 17.36.040)
