Wind Access Setbacks.

No accessory WECS shall be located where the center of the tower is within a distance of five rotor diameters from a lot line that is perpendicular to and downwind of, or within forty-five (45) degrees of perpendicular to and downwind of, the dominant wind direction.

Notwithstanding the provisions of subsection (C)(1) of this section, such setbacks from lot lines do not apply if the application is accompanied by a legally enforceable agreement for a period of twenty-five (25) years or the life of the permit, whichever is longer, that the adjacent landowner agrees to the elimination of the setback and will not develop his land in such a way as to decrease wind velocity or increase wind turbulence at the location of the proposed accessory WECS. In addition the provisions of subsection (C)(1) of this section, regarding setbacks from lot lines do not apply if the planning director determines that the characteristics of the downwind property, such as, but not necessarily limited to, topography or use of such property as a transportation corridor, eliminate the ability to develop the downwind property with WECS. Whenever a wind access setback reduction is proposed to the planning director based on the characteristics of the downwind property, the wind access setback reduction shall be included in all notices regarding the accessory WECS permit, and, if granted, the accessory WECS permit shall specifically state the required alternative wind access setback.

D.

Scenic Resource Protection.

No accessory WECS or WECS array shall be located easterly of Indian Avenue or northerly of Pierson Boulevard and its extension westerly of Highway 62.

The WECS shall not be operated in a manner that causes communications interference. In the event that communications interference is caused by the WECS, the operator shall take the necessary steps to remedy the situation or shall terminate operation.

L.

The WECS shall not create noise beyond the lot containing the WECS which exceeds sixty (60) db(A) as measured at a point ten (10) feet from the outer wall, or equivalent distance, to any habitable dwelling, hospital, school, library or nursing home.

M.

The foundation, tower and compatibility of the tower with the rotor and rotor related equipment shall be certified in writing by a structural engineer registered in California, that they conform with good engineering practices and comply with the appropriate provisions of the Uniform Building Code that have been adopted by the county.

As an alternative to certification of the mechanical system as provided above, the applicant may present a statement from either a registered engineer or an independent testing laboratory recognized by the county that the system complies with standards developed by the American Wind Energy Association or other accepted standards organization.

N.

Every unsafe accessory WECS and every accessory WECS which has been inoperable for six months is declared to be a public nuisance which shall be abated by repair, rehabilitation, demolition or removal in accordance with the procedure contained in Section 3 of county Ordinance No. 457.
