Norton Shores City Zoning Code

ARTICLE XIV

WIND TURBINES AND WIND ENERGY FACILITIES

Sec. 48-1381.- Purpose and intent.

The purpose of this section is to establish guidelines for siting wind turbines and wind energy facilities. This section's goals are as follows:

(1)

To promote the safe, effective, and efficient use of wind turbines and wind energy systems installed to reduce the on-site consumption of electricity supplied by utility companies.

(2)

To lessen potential adverse impacts wind turbines and wind energy facilities may have on residential areas and land uses through careful design, siting, noise limitations, and innovative camouflaging techniques.

(3)

To avoid potential damage to adjacent properties from turbine failure through engineering and proper siting of turbine structures.

(Ord. No. 702, § 2, 8-6-2008; Ord. No. 714, § 2, 7-17-2009)

Sec. 48-1382. - Definitions.

The following words, terms, and phrases, when used in this article, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning:

Applicant means the person or entity filing an application under this article.

Facility owner means the entity or entities having an equity interest in a wind energy facility, including their respective successors and assigns.

Hub height means the distance measured from the surface of the tower foundation to the height of the wind turbine hub, to which the blade is attached.

Nonparticipating landowner means any landowner except those on whose property all or a portion of a wind energy facility is located pursuant to an agreement with the facility owner or operator.

Occupied building means a residence, school, hospital, church, public library or other building used for public gathering that is occupied or in use when the permit application is submitted.

Operator means the entity responsible for the day-to-day operation and maintenance of a wind energy facility.

Roof-mounted wind turbine means a single wind energy conversion system that is mounted to the roof of any structure with a maximum rotor diameter of seven feet.

Turbine height means the distance measured from the surface of the tower foundation to the highest point of the turbine rotor plane.

Wind turbine means a freestanding or roof-mounted, single wind energy conversion system that converts wind energy into electricity through the use of a wind turbine generator, and includes the nacelle, rotor, tower, and pad transformer, if any. This may also include an anemometer.

Wind energy facility means an electric generating facility, whose main purpose is to supply electricity, consisting of one or more wind turbines and other accessory structures and buildings, including substations, meteorological towers, electrical infrastructure, transmission lines and other appurtenant structures and facilities.

Sec. 48-1383. - Permitted uses.

(a)

A single wind turbine not to exceed 70 feet in height shall be considered a permitted accessory use on a single parcel in any zoning district, if it meets the standards and requirements of this section.

(b)

A single wind turbine not to exceed 200 feet in height shall be considered a permitted accessory use on a single parcel in any district where GI General Industrial is listed as a principal or special use if it meets the standards and requirements of this section.

(c)

Roof-mounted turbines shall be considered a permitted accessory use on parcels in any nonresidential zoning district with a minimum separation of at least one rotor/blade diameter.

(d)

One roof-mounted wind turbine shall be considered a permitted accessory use on any residentially zoned parcel. A second roof-mounted unit on a residentially zoned parcel necessitates the issuance of a special use permit with a minimum separation between the units of at least one rotor/blade diameter.

(e)

A single wind turbine 70—200 feet in height shall be considered a special use in any residential development, existing or proposed, subject to the standards and requirements of this section. Said turbine would be in lieu of future, individual wind turbines on individual parcels within the development.
