Have any of you guys had to deal with these in development review? Basically, I'm taking about the type of small wind turbine with a vertical shaft that looks like a roof mechanical and only extrudes a few feet beyond the roofline. There is nothing in our code that deals with these at all. We require that roof mechanicals be screened, but in the case of one of these, if you screen it, it won't function since it needs airflow to work. We haven't had one of these before the boards yet - our Planning Board chair brought this up as a hypothetical scenario. Thoughts?
