§ 422. Utility WECS

A. Process. Utility Wind Energy Conversion Systems (WECS) as defined in this Ordinance with specifications as contained in Section 508G shall be allowed only in the Public Utility Zone and then only upon the granting of a Special Use Permit by the Zoning Board of Review. Such use shall also require Development Plan Review by the Planning Board under the provisions of Section 704

B. Application Requirements. In addition to the existing conditions plan and the site plan required for any development within the PU Zone, an application for a Utility WECS shall include the following:

1. A complete set of plans for the proposed wind turbine, including all manufacturer specifications and details;

2. An analysis of soils from the site of the proposed turbine that evaluates bearing capacity, and which includes a core sample tested for the presence of any environmental contaminants;

3. Structural design and installation plans prepared by a Rhode Island registered professional engineer;

4. Manufacturer's documentation of noise impacts of the turbine under various wind conditions, including a chart or map indicating the expected decibel levels at given distances from the turbine;

5. A visual representation of the proposed wind turbine as viewed from surrounding properties as well as from other areas of the island from which the turbine will be visible, including from roadways, areas of higher elevation and publicly owned or protected scenic and conservation areas;

6. An evaluation of the shutter or flicker effect (shadows caused by sunlight passing through the moving blades) of the turbine as it is sited on the parcel, including the seasonal times and duration, and a delineation of the areas impacted; and

7. An evaluation of the potential impact of the turbine on birds and other wildlife, including review of dominant bird species, and migratory, nesting and feeding patterns.

C. Standards of Review. Prior to the approval of an application for a Utility WECS, the Zoning Board of Review shall determine that the application meets the general criteria for a Special Use Permit contained in Section 401. In addition, the Zoning Board shall determine that the following standards are met:

1. The limitations on wind turbine size, noise levels and lighting impacts contained in Section 508G;

2. Potential adverse impacts on birdlife and wildlife are minimized through appropriate siting and design of the facility; and

3. The public convenience and welfare will be substantially served and there will not be resulting conditions inimical to the public health and safety.
