§ 40-737. Exceptions to height requirements.  


Latest version.
  • The height regulations as stated in this ordinance shall not apply to the following uses. Additional exceptions to height regulations are located in the height requirements section of the Multiple-family Residential District R-3, the Condominium District R-1CO, the Medical Service District H-2, the Neighborhood Commercial District C-1, the General Offices District GO-1, the Core District-Residential CD-R, the Business Core District BC-1, the Business Core District BC-2, the Mixed-use Corridor District MUCD, and the General Commercial District C-2. Buildings or structures located in the Business Core District (BC-2) exceeding the maximum height allowed by right of that district shall be governed by the exceptions to height regulations of the BC-2 district rather than the regulations of this section, except that additional or more restrictive regulations listed in section 40-737(4) below shall apply. Buildings or structures located in the Unrestricted Suburban District (U-1S) exceeding the maximum height allowed by right of that district shall be governed by the regulations of section 33-5.21. Mid-rise to high-rise building in Chapter 33 Unified Development Code, Article 5, Supplemental Conditions of this Code.

    (1)

    Churches; schools; hospitals; sanitariums; public, semi-public and public service buildings; office buildings; and institutions. There shall be no restrictions on the height of such buildings, provided the front, side, and rear façades shall use bulk planes which begin at horizontal lines located directly above the lines created by the setback, at a height equal to the maximum height permitted by right in the applicable zoning district, and rise over the lot upward at a forty-five-degree angle equal to a pitch of one (1) foot additional vertical distance for each one (1) foot additional horizontal distance.

    (2)

    Barns, silos and other farm structures when located on farms, belfries, cupolas, domes, flagpoles and monuments, water towers, windmills, chimneys, smoke stacks, conveyors, fire towers, and oil derricks.

    (3)

    Bulk heads, elevator penthouses, water tanks, cooling towers, scenery lofts and similar structures provided that such structures shall cover not more than twenty-five (25) percent of the total roof area of the building on which such structure is located.

    (4)

    Transmission towers, radio towers, mast and aerials/or antennas

    a.

    General.

    1.

    Commercial transmission towers, radio towers, masts, aerials and/or antennas shall be located only in the Neighborhood Commercial, C-1, and the less restrictive zoning districts, subject to criteria listed in paragraph b., Criteria, below.

    2.

    Only cellular phone transmission towers and their associated support buildings will be allowed in the General Office Districts, GO-2 and GO-1, the Medical Service Districts, H-1 and H-2 subject to criteria listed in paragraph b., Criteria, below, and excluding subsection (4)b.1., Distance Requirements to Residential Development.

    3.

    Only monopole cellular phone transmission towers and their associated support buildings shall be allowed in the residential districts, provided the following criteria are met:

    i.

    No new cell may be established if there is a technically-suitable place available on an existing communications tower within the search area that the new cell site is to serve. For the purpose of this ordinance, the search area is defined as the grid for the placement of the antenna.

    ii.

    The minimum lot size on which a cellular tower is to be located shall be the minimum lot size for the residential district, or five thousand (5,000) square feet, whichever is greater, and shall be of sufficient size to contain on-site any debris from tower failure.

    iii.

    No new cellular towers will be allowed with a one thousand (1,000) foot radius of an existing cellular tower within a residential district.

    iv.

    Permitted height: Cellular towers fifty (50) feet in height or less, or five (5) feet above the tree line shall be permitted. In no case shall the height of any tower be greater than sixty-five (65) feet.

    v.

    Setbacks:

    A.

    The tower must be set back from all property lines by a distance of twenty (20) percent of the height of the tower or by the rear yard setback required for the underlying zoning district, whichever is greater.

    B.

    All associated support buildings must meet the minimum setback standards for accessory structures in the underlying zoning district and shall not be used for offices, long-term vehicle storage, or other outdoor storage.

    C.

    In no case shall a cellular tower be located in the required front yard of a residential structure or lot.

    vi.

    Landscape, buffer and general design standards:

    A.

    Existing on-site vegetation shall be preserved to the maximum extent practical. All towers shall be landscaped with at least one (1) row of evergreen shrubs or trees or shrubs within twenty (20) feet of the tower's base. Such trees shall be a minimum of four (4) feet high when planted and spaced not more than fifteen (15) feet apart. These trees and shrubs shall be planted in any configuration which will serve to better buffer the site.

    B.

    General design standards:

    I.

    The entire facility must be aesthetically and architecturally compatible with its environment. The use of residentially-compatible materials such as wood, brick or stucco is required for associated support buildings, which shall be designed to architecturally match the exterior of residential structures within the neighborhood. In no case will metal exteriors be allowed for accessory buildings.

    II.

    The tower itself must be of such design and treated with an architectural material so that it is camouflaged to resemble a woody tree with a single trunk and branches on its upper part.

    C.

    Fences: Walls or fences constructed of wood, brick or masonry shall be used to secure the site and provide an opaque barrier. Such walls or fences shall be used in conjunction with landscaping to provide security or increase the buffer with adjacent residential uses. In no case will barbed wire or razor wire fencing be permitted in residential districts.

    vii.

    Structural integrity: Cellular transmission towers shall be certified by an engineer to withstand a minimum wind load of one hundred fifty (150) MPH and a maximum gust load of two hundred (200) MPH. The tower and any proposed transmission equipment must be certified to meet any structural standards for steel antenna towers and support structures set in the Electronic Industries Association/Telecommunications Association Standards referenced as EIA/TIA-222-E and as amended hereafter.

    viii.

    Visual impact mitigation:

    A.

    Color: The cellular transmission tower shall be constructed of a material with a neutral color and shall be designed to blend in with the surrounding landscape and uses.

    B.

    Lighting: When lighting is required and is permitted by the Federal Aviation Administration or other federal or state authority, it shall be orientated inward so as not to project onto surrounding residential property.

    C.

    Design: The design criteria for cellular towers and their associated support buildings shall follow the provisions outlined above in section 40-737(4)a.3.vi.B.I., General Design Standards.

    ix.
