Setbacks
The most common regulation of wind turbine placement is in limiting how close they can be to dwellings, wetlands, eagle nests, roads and paths, workplaces, schools, parks, etc.[1]
The first consideration is safety, in case of blade failure, fire, or tower collapse.[2] Other safety concerns include icing and consequent shedding in northern climates and aircraft, not only near airports but also in farming areas where crop-dusting is common and in rural areas dependent on helicopter ambulance service.
Setbacks should further address noise, shadow flicker, and aesthetics.
