This definition is meant to include but not be limited to what are commonly referred to as satellite earth stations, TVROS, and microwave antennas." SECTION 3. Section 18.08.045 of the Ashland Municipal Code is hereby changed to Section 18.08.485 and is amended by adding "disc antenna" to the list of covered equipment. SECTION 4.

A new Section 18.72.160 is hereby added to the Ashland Municipal Code to read as follows: "18.72.160 Development Standards for Disc Antennas A. Building Permit Required All disc antenn~s shall be subject to the review and approval of the building official where required by the Building Code. -1- 1< B. Development Standards All disc antennas shall be located, designed, constructed, treated, and maintained in accordance with the following standards: (1) Antennas shall be installed and maintained in compliance with the requirements of the Building Code. (2) Disc antennas exceeding thirty-six (36) inches in diameter shall not be permitted on the roof, except where there is no other location on the lot which provides access to receiving or transmitting signals. In no case shall any part of any antenna be located more than 10 feet above the apex of the roof surface. Antennas mounted on the roof shall be located in the least visible location as viewed from adjacent public rights-of-ways, and residential structures in residential zones. (3) No more than one disc antenna shall be permitted on each tract of land. (4) Ground mounted disc antennas shall be erected or maintained to the rear of the main building, except in those instances when the subject property is 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. Antennas 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. (5) Antennas may be 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 building. (6) 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 shall 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, or reflective. Whenever possible, disc antennas shall be constructed out of mesh material and painted a color that will blend with the background. -2- . I. (7) Antennas shall meet all manufacturer's specifications. The mast or tower shall be non-combustible. Corrosive hardware, such as brackets, turnbuckles, clips, and similar type equipment if used, shall be protected by plating or otherwise to guard against corrosion. (8) Every antenna must be adequately grounded, for protection against a direct strike of lightning, 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 lightning 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. Lightning arrestors shall be used that 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, lightning arrestors must be installed in each conductor. When coaxial cable or shielded twin lead is used for lead-in, suitable protection may be provided without lightning arrestors by grounding the exterior metal sheath. (9) Antennas may contain no sign or graphic design as defined in the Ashland Sign Code, even if the sign is permitted on the property."
