Home My WebLink AboutA001 - Council Action form dated November 15, 1983 ITEM NO: MEETING DATE: 11/15/83 COUNCIL ACTION FORM SUBJECT: Dish Antennas BACKGROUND: The Council requested that the Department of Planning and Housing and the Planning and Zoning Commission look into the regulation of dish antennas for television reception. The Department received two examples of ordinances which relate to dish antennas from the Planning Advisory Service of the American Planning Association. One of the examples dealt specifically with the regulation of satellite television antennas in residential, commercial, and industrial zoning districts. The second ordinance was a very detailed proposal that dealt with the regulation of all radio and television antennas. Both sample ordinances are attached. Based on the examples from the Planning Advisory Service the Department prepared two sample ordinance amendments for discussion and review by the Planning and Zoning Commission at their meeting on October 19, 1983. The Commission reviewed both proposed ordinance amendments. The discussion included whether or not any problems had arisen in the community in connection with dish antennas, and whether or not it was necessary to have the intensive regulation of all radio and television antennas as proposed in the second ordinance amendment. The Commission agreed that some controls over dish antennas were necessary, but that the proposed ordinance amendment dealing with radio and television antennas was too extensive. The following action was taken: MOTION: (Fouts/Manatt) Submit to City Council our recommendation that the shorter proposal on the regulation of satellite television antennas be recommended for approval. Motion carried unanimously. The staff has contacted a local distributor of dish antennas as well as Heritage Cablevision. Neither expressed any concerns about the proposed limitations set out in the proposed regulations. ALTERNATIVES: 1 . Approve the ordinance amendment concept for the regulations of satellite television antennas and instruct the city attorney to put it into ordinance form. 2. Approve the ordinance amendment concept for the regulation of all radio and television antennas and instruct the city attorney to put it into ordinance form. 2 3. Refer the proposed ordinance amendments back to staff for modification. 4. Take no action. MANAGER'S RECOMMENDED ACTION: The City Manager recommends the City Council accept Alternative No. 1 since this proposal directly addresses the regulation of dish antennas. COUNCIL ACTION: Agenda Item # V.1 . 10/10/83 REGULATION OF SATELLITE TELEVISION ANTENNAS INSTALLATION PERMIT - REQUIRED Every person intending to install or materially reconstruct a satellite television antenna shall apply for and receive a building permit from the City before installing or commencing work on the antenna structure. The antenna shall meet all required setbacks. SATELLITE TELEVISION ANTENNAS A. Any satellite television antenna in any residential zoning district shall have a maximum height of twenty (20) feet, shall be located on the rear one-half of the lot, shall be at least ten (10) feet from any main buildin existing or under construction on the same lot, shall be at least five (5� feet from any rear or side property line, and, in the case of a corner lot, shall not project beyond the front yard required or existing on the adjacent lot. In the case of an interior lot abutting upon two or more streets, a satellite television antenna shall not be erected or altered so as to encroach upon the one-quarter of the lot nearest either street or in any case, the front yard required for either street. B. In any commercial or industrial district, a satellite television antenna shall not exceed forty-five (45) feet in height nor be located closer than fifteen (125) feet to any public street . If used for advertising purposes, a satellite television antenna shall be deemed to be a sign and shall also be governed by the sign regulations applicable to the property. Where a satellite television antenna is proposed to be mounted on the roof of a building, it shall not extend more than ten (10) feet above the height limit established for the district in which the structure is located and such antenna shall not be used for any commercial or advertising purposes. Agenda Item # V.I. 10/10/83 RADIO AND TELEVISION ANTENNAS Radio and television antennas may be installed, erected, and maintained within all land use zones of the City bift only in accordance with the provisions of this section. The term "antenna," as used herein, means any system of wires, poles, rods, reflecting dishes, or similar devices used for the transmission or reception of electromagnetic waves which system is external to or attached to the exterior of any building. Antennas shall include devices having active elements extending in any direction, and directional beam-type arrays having elements carried by and disposed from a generally horizontal boom which may be mounted upon and rotated through a vertical mast or tower interconnecting the boom and antenna support, all of which elements are deemed to be a part of the antenna. The height of an antenna shall be the total maximum to which it is capable of being raised and shall be measured from the highest point of the finished grade adjacent to the structure if ground-mounted or from the peak of the roof if roof-mounted. All antennas shall be subject to the following: (1) Approval of Antennas. (a) All antennas shall be subject to the review and approval of the buildng official where required by the Building Code. (b) Ground-mounted antennas exceeding forty-five (45) feet in height may be permitted if a conditional use permit is granted in conformity with Section and this section, provided that no antenna shall exceed seventy (70) feet . (2) Development Standards. All antennas shall be located, designed, constructed, treated, and maintained in accordance with the following standards: (a) Antennas shall be installed and maintained in compliance with the requirements of the Building Code. (b) Antennas which are roof-mounted shall not extend higher than fifteen (15) feet above the peak of the roof, except a single-vertical pole antenna may extend to twenty (20) feet above the peak of the roof. Dish antennas exceeding twenty-four (24) inches in diameter shall not be permitted on the roof. (c) Not more than one ground-mounted antenna exceeding forty-five (45) feet in height shall be permitted on each lot . (d) Antennas shall be erected or maintained to the rear of the main building, except in those instances when the subject property is a cul-de-sac or corner lot where the side yard is larger than the rear yard in which case the antenna may be located in the side yard. Antenna towers shall not be located in any required setback area. No portion of an antenna array shall extend beyond the property lines or into any front yard area. Guy wires shall not be anchored within any front yard area, but may be attached to the building. (e) Antennas may be roof- or ground-mounted, free-standing or supported by guy wires, buildings or other structures in compliance with the manufacturer' s structural specifications. Ground-mounted antennas shall be any antenna with its base mounted directly in the ground, even if such antenna is supported or attached to the wall of a buildng. Fixed-guyed antenna towers shall be fascia-mounted or guyed according to approved standards. Wire antennas that are not self-supporting shall be supported by objects within the property lines, but not within any front yard areas. (f) The antenna, including guy wires, supporting structures and accessory equipment shall be located and designed so as to minimize the visual impact on surrounding properties and from public streets . Antennas should be screened through the addition of architectural features and/or landscaping that harmonize with the elements and characteristics of the property. The materials used in constructing the antenna shall not be unnecessarily bright, shiny, garish, Gr reflective. (g) Antennas shall meet all manufacturer' s specifications. The mast or tower shall be of noncombustible and corrosive-resistant material . The miscellaneous hardware, such as brackets, turnbuckles, clips, and similar type equipment subject to rust or corrosion, shall be protected with a zinc or cadmium coating by either galvanizing or sherardizing process after forming. These finishes are selected to guard against corrosion and to protect the elements against electrolytic action due to the use of adjoining dissimilar metals. (h) Whenever it is necessary to install an antenna near power lines, or where damage would be caused by its falling, a separate safety wire must be attached to the antenna mast or tower, and secured in a direction away from the hazard. Transmission lines must be kept at least twenty four (24) inches clear of telephone or light wires. ( i) Every antenna must be adequately grounded for protection against a direct strike of lightening, with an adequate ground wire. Ground wires shall be of the type approved by the latest edition of the Electrical Code for grounding masts and lightening arrestors, and shall be installed in a mechanical manner with as few bends as possible, maintaining a clearance of at least two inches from combustible materials. Lightening arrestors shall be used, which are approved as safe by the Underwriters' Laboratories, Inc. , and both sides of the line must be adequately protected with proper arrestors to remove static charges accumulated on the line. When lead-in conductors of polyethylene ribbon-type are used, lightening arrestors must be installed in each conductor. When coaxial cable or sheilded twin lead is used for lead-in, suitable protection may be provided without lightening arrestors by grounding the exterior metal sheath. (3) Application for Approval . Prior to installing any antenna for which approval is required pursuant to subsection (1) of this section, an application shall be submitted to and approved by the appropriate authorized agency. The application shall be accompanied by construction drawings showing the proposed method of installation, the manufacturer' s specifications, if any, and a plot plan showing the location of the antenna, property and setback lines, and all structures. In addition, applications shall be accompanied by engineering data establishing the fact that the antenna conforms to the structural requirements of the Building Code. Such engineering data may include custom engineering calculations for each installation, the calculations and data to be submitted by a structural or civil engieer registered by the State of Iowa. Such registered engineer may be employed by the manufacturer of the antenna. (4) Enforcement. (a) All antennas shall be maintained in good condition and in accordance with all requirements of this section. (b) All antennas shall be subject to periodic reinspection . No additions, changes, or modifications shall be made to an antenna, unless the addition, change, or modification is in conformity with the Building Code and Conditional Use Permit, if any. (c) Failure to abide by and faithfully comply with this section or with any and all conditions that may be attached to the granting of any Conditional Use Permit shall constitute grounds for the revocation of the approval of permit by the City Council . The remedies provided for herein shall be cumulative with all other remedies provided in this Code and not exclusive. 75 O rJ c y U H e ' E -C c Y E .� n °mac a E 72 E � � •a � � � � � w o C ai y •� CI O .C 3 O O E"O rs w M 9 4E N C v V �r r3 17 Q v rtS � C v o � Ey p 7:1 p c c p �3 71 ' m tG C rtf rJ' "= 7 -= E C LL' Ln s19 z tx b o o a w do wb y _ z o N C A M �d' L!7 O C�O � Lz] CQ�.
