§ 153.080 WIRELESS TELECOMMUNICATIONS SERVICE.
   (A)   A proposal for a new commercial wireless telecommunication service tower shall not be approved if one or more of the following conditions exist:
      (1)   Existing or approved towers and/or buildings within the search area radius could accommodate the planned equipment at a height necessary to function properly, as documented by a qualified and licensed professional engineer;
      (2)   The planned equipment would exceed the structural capacity of the existing or approved tower or building, as documented by a qualified and licensed professional engineer, and the existing or approved tower cannot be reinforced, modified, or replaced to accommodate planned or equivalent equipment;
      (3)   The planned equipment would cause interference materially impacting the usability of other existing or planned equipment at the tower or building, as documented by a qualified and licensed professional engineer.
   (B)   Any proposed commercial wireless telecommunications service tower shall be designed in all respects, including structurally and electrically, to accommodate the applicant's antennas and comparable antennas for at least two additional users if the tower is more than 100 feet in height or for one additional user if the tower is less than 100 feet but more than 60 feet in height. Towers must be designed to allow for future rearrangement of antennas upon the tower and to accept antennas mounted at varying heights.
   (C)   Proof of non-interference. Each application for construction of a wireless telecommunication facility shall include either a preliminary or a certified statement that the construction of the tower, including reception and transmission functions, will not interfere with radio, television or other types of public or community wide communications services. In the event only a preliminary statement is submitted with the application, a final certified statement of non-interference will be provided and approved by the city prior to issuance of a building permit. The statement shall be prepared by an engineer licensed to practice in the State of Minnesota or other professional who would be accepted by the city.
   (D)   Performance standards for towers.
      (1)   Lot area. See Appendix B for minimum lot sizes. If additional setbacks are required, additional lot size may be mandated to meet setback requirements.
      (2)   Setbacks.
         (a)   If the tower is designed to collapse in upon itself, the structural setbacks for towers need to conform to the setbacks established in the zoning district standards Appendix B of this chapter.
         (b)   If the tower is not self collapsing, the setbacks from all property lines shall be equal to the height of the tower.
      (3)   One accessory building will be permitted on each tower site, but shall be limited to one story in height, have no more than 1,500 square feet in floor area, and shall conform to all structural setback requirements of Appendix B.
      (4)   Towers shall be enclosed within security fencing to prevent unauthorized entry.
   (E)   Lighting. All lighting on tower sites shall meet FAA or FCC requirements and shall not result in glare on adjacent property.
   (F)   Obsolete or unused towers. All obsolete and unused towers and accompanying accessory facilities shall be removed by the property owner within 12 months of the cessation of their use.
