§ 3-3. Dimensional requirements.

To provide for at least minimal operational safety for persons and property located outside of a wind farm, all wind energy facilities shall comply with the minimums and maximums contained in the following tabulation:

Type of Wind Energy Facility	Minimum Wind Turbine Setback From Any Property Line, Vacant or Occupied Dwelling Unit, Public or Private R-O-W, and/or Access Easement	Maximum Wind Turbine Height*
Small System (up to 25 kW) Attached to a house	None	60 feet
Small System (up to 25 kW) Not attached to a house	1 foot for each foot of height from any property line and 1 foot for each foot of height from any vacant or occupied dwelling unit on the same property but If the Planning Director or designee determines there will be no significant impact on abutting properties or those across a stream, lake, or other body of water, no such setback is required from the waterward property line for a turbine placed in a body of water or on a dock or pier.	75 feet
Large System (more than 25 kW and less than 1,000 kW)	1,300 feet	199 feet
Utility-scale (1,000 kW or more)	One mile	275 feet
* Height is measured from the lowest adjacent grade to the highest point of the structure, including any attachments, such as a lightening [lightning] protection device or a turbine rotor or tip of the turbine blade when it reaches its highest elevation.

 

Such minimum setbacks for a wind energy facility shall be measured from its outermost extension (whether blade tip, nacelle/turbine housing, or tower/pole edge) that is nearest the subject property line, vacant or occupied dwelling unit, public or private R-O-W, and access easement. To measure maximum height, see the Definitions.

No portion of any wind turbine blade shall be closer than 25 feet to any portion of the ground that surrounds any wind energy facility.
