The city may require an abandoned tower to be removed. The owner of such tower shall remove the tower within 30 days of receipt of written notice from the city. If the tower is not removed within 30 days, the city may remove it at the owner's expense and any special exception approval of the tower shall be deemed to have expired.
         (b)   Exemptions. The following shall be exempt from the standards of this section (but shall be required to comply with other relevant standards in this ZDO, such as accessory use or design standards):
            1.   Receive-only television or radio antennas for non-commercial use.
            2.   Antennas legally operated by FCC-licensed amateur radio operators.
         (c)   Color.
            1.   Freestanding telecommunications facilities shall either maintain a galvanized steel finish or, subject to any applicable standards of the FAA, be painted a neutral color (i.e., light grey) to reduce visual obtrusiveness.
            2.   At a freestanding telecommunications facilities site, the design of buildings and related structures shall, to the maximum extent practicable, use materials, colors, textures, screening, and landscaping that will blend them into the natural setting and surrounding buildings.
         (d)   Setbacks.
            1.   Freestanding towers, guy anchors, and equipment buildings shall meet the minimum setback requirements for the zoning district where located (See Chapter 165: Dimensional Standards).
            2.   A freestanding tower shall be setback a minimum distance equal to one-half the height of the tower from any single- or two-family dwelling. For guyed towers, the setback shall be measured from a line connecting the outermost anchor points for guy wires.
         (e)   Height. The height of a freestanding tower shall not exceed 200 feet.
         (f)   Lighting. Night-time strobe lighting shall not be incorporated unless required by the Federal Communications Commission, Federal Aviation Administration or other regulatory agencies.
         (g)   Signage. The freestanding tower or antenna shall not include signage.
         (h)   Landscaping. Freestanding telecommunications facilities shall comply with the following landscape standards:
            1.   Freestanding telecommunications facilities (including equipment structures and cabinets) shall be landscaped with a buffer of plant materials that effectively screens the view of the ground-based portion of the tower facility from existing residential development.
            2.   Existing mature tree growth and natural land forms on the site shall be preserved to the maximum extent possible.
         (i)   Separation. If an applicant proposes a new freestanding telecommunications facility within 1,200 feet of an existing freestanding telecommunications facility, the applicant shall submit a statement indicating the reasons why the existing tower(s) was inadequate or unavailable for collocation. The Zoning Administrator shall allow the owner of such existing tower an opportunity to comment prior to making a decision.
         (j)   Collocation. New freestanding towers shall be designed to accommodate the present and future needs of the owner and at least one comparable user. Unused space on an existing tower shall be made available to other users at a fair market value.
         (k)   Single lot. Towers, guy anchors, equipment buildings, and any other appurtenances related to a freestanding telecommunications facility shall be located on a single parcel or tract of land.
         (l)   Safety.

If such standards and regulations change, owners shall be responsible for bringing the towers and antennas into compliance with the changed standards and regulations within six months of their effective date, unless a different compliance schedule is mandated by the controlling regulations. (Failure to maintain freestanding telecommunications facilities in compliance shall constitute grounds for removal of the tower or antenna, at the owner's expense.)
         (q)   Franchises and licenses. It shall be demonstrated all franchises and licenses required by law for the construction or operation of a tower or antenna have been obtained.
         (r)   Availability of other suitable locations. New freestanding towers shall not be permitted unless the applicant demonstrates that no existing freestanding communication tower or other structure can accommodate the applicant's needs. Evidence submitted to demonstrate that no existing tower or structure can accommodate the applicant's needs shall be signed by a registered engineer and shall demonstrate at least one of the following:
            1.   No existing communication towers or structures at a suitable height are located within the geographic area required to meet the applicant's engineering requirements;
            2.   Existing freestanding towers or structures do not have sufficient structural strength to support applicant's proposed antenna and related equipment;
            3.   The applicant's proposed antenna would cause electromagnetic interference with the antennas on the existing towers or structures, or the antennas on the existing towers or structures would cause interference with the applicant's proposed antenna; or
            4.   The applicant demonstrates that there are other limiting factors that render existing towers and structures unusable.
      (3)   Utility, major. An electrical power facility, substation, or transmission station shall comply with the following standards:
