No sorry that's not what I meant:
You're fighting town council over tower restrictions. They've made up restrictions based on some "received wisdom". But the experience of some people is that the received wisdom is wrong!
I was recently talking to the installer of RE systems in a nearby town. His shop is right inside town, in fact, there are houses on the same block. There are two towers behind his shop, one 45' tall with a small turbine on it, another 80' tall with a much larger one. The 45' tower is older. It's a 8" diameter self-supporting pole with no guy wires. When it went up, the town council got some complaints about the noise and how it looked. Recently, the RE guy installed the 80' tower and put a ARE 442 on it. Much bigger, and the tower is a huge self-supporting truss. You can see it from the other side of town. After that one went up, the RE company braced themselves for a new 'round of complaints from the residents.
Not a word.
There's a to be lesson in this!
People look ahead, around, but they don't often look up. If there are some municipalities getting complaints about wind turbines, and they are on towers X feet high, then "obviously" there would be more complaints if the tower was higher than "X". This is not necessarily true. A higher tower may get it out of people's field of view. Then they don't notice it any more, can't hear it as easily, either.
This may be a very subtle point, (some city councillors only understand yelling and fist-waving) but it's just another reason for your town council not to accept the "received wisdom", because it could be wrong. Once you dig into the assumptions about why any rule came about, you may find a reason, or maybe no logic whatsoever.
Of course all I can give you is "a guy on the internet told me this". Whenever fighting city hall, you need to have more evidence than that. All I think I can offer is another idea to help you challenge their assumptions, maybe sharpen your logic. I'd hate to be in your shoes, but with a little luck you'll get what you need.
PS The guy's tower may be a Rohn, too. If you want to get his story directly you can call Boyd Solar (403) 335-3330. Ask for Sean. Let him know that you know me (Steven Fahey, who bought the CTI solar panels from him in January), and see if he has a minute to tell you about the tower.
