Wind energy conversion systems (WECS) may be permitted subject to the following requirements:
   (a)   The minimum distance from any lot line or overhead power line to any tower, pole or other support structure of the wind energy conversion system shall be established by the following minimum standards:
Rotor Diameter (Feet)
Setback Distance (Feet)
Rotor Diameter (Feet)
Setback Distance (Feet)
   (b)   Intermediate rotor size distances shall be interpolated from the above values.
   (c)   The WECS shall not be located in any required yard.
   (d)   The WECS shall not cause interference to microwave communications or radio and television reception in the area. Noise levels measured at the lot line shall not exceed 60 DBA in a residential zone.
   (e)   To limit climbing access to WECS tower, or other support structure, a six foot high fence with locking portal shall be place around the WECS support or if a tower is utilized, the tower climbing apparatus shall be limited to no lower than 12 feet from the ground or the WECS support may be mounted on a rooftop.
   (f)   All blades of a WECS shall be constructed of non-metallic substances. If the applicant can prove, in writing form, that no electromagnetic interference will result, a metal content of up to 25% will be acceptable.
   (g)   The WECS shall be located in compliance with the guidelines of the Federal Aviation Regulations with regard to airport approach and clearance around VOR and DVOR stations.
   (h)   Height of the WECS shall not exceed the maximum height restriction in the zone where it is located by more than 20 feet The height of the WECS shall be measured at the center of the blade diameter.
   (i)   Data pertaining to the WECS' safety and structural integrity shall be certified by a licensed engineer and filed with the building permit application. The tower or support and top adapter shall meet the restrictions specified in the city's building code.
   (j)   The WECS, if interconnected to a utility system, shall meet the requirements for interconnection and operation as set forth in the electric utility's current service regulations applicable to WECS.
   (k)   A plot plan shall be submitted with the application for building permit showing the proposed location and height of the WECS, fencing and all existing buildings within 200 feet of the exterior lot lines.
   (l)   The owner/operator shall provide covenants, easements or similar documentation to assure sufficient wind to operate the WECS unless adequate accessibility to the wind is provided by the site.
   (m)   The owner/operator shall certify that the WECS does not violate any covenants of record.
   (n)   The applicant shall provide a certificate of liability insurance. Annually the owner/operator shall present evidence to the Zoning Administrator that the liability insurance is still in effect.
