Hi fabricator,
In your situation I'd be tempted to either circumvent the rules or comply with them rather than fight them. Fighting the system can cost you more than a good tower. Besides, those bureaucrats are like elephants when it comes to remembering somebody who messed with them and getting even.
How tall of a tower do you need? Is your land flat or hilly? Is it treed or barren?
You live on eighty acres, so you got lots of dirt, and lots of space. If you have a tractor with a front end loader, I'd be tempted to build a thirty to forty foot high dirt mound, then put a 20 foot monopole on top of it. As URL suggested, the monopole could be a hinged lamp post. Or a 20 foot section of used pipe, supported at the bottom half by three smaller diameter pipes arranged in triangular fashion as viewed from above. That approach would probably be cheaper than a guy wire tower, that steel tubing is expensive. If your soil is rocky that's even better, because you could stack the dirt with a pretty steep angle of repose, minimizing the amount of dirt needed.
If your property has tall trees, another circumventing approach might be to put in the regular guy wire tower you were planning to use, but put it close to a tall tree, then secure it to the tree about ten feet down from the wind turbine and remove the guy wires and get your permit signed off. Put 'em back on when you want to lower the tower. Remove all the tree branches and leave just the trunk to minimize sway in high winds. You gotta remember, that once your permit is signed off, the bureaucrats won't bother you again unless somebody complains, and that doesn't seem likely in your case.
That ordinance provision banning guy wire towers was probably put in because somebody considered guy-wire towers unsightly. I went to all the trouble to put in beautiful 56 foot tall, hydraulically operated tapered monopole towers, and I still hear through the grapevine that some of my neighbors are complaining that they are an eyesore. Just plain old human jealousy. 'Course, I only have twelve acres so my neighbors are a bit closer.
I haven't posted for a while because I'm just coming off a three day suspension that TomW imposed on me for refusing to stop defending Chinese products against attack by unknowledgeable people, so I'm going out on a limb here with this next suggestion. My next suspension will be permanent, according to Tom, so if you never hear from me again, I got booted. Two strikes and you're out.
If you decide to put up a monopole tower, order it directly from the factory in China. It will be less than half price. My experience indicates that you needn't worry about sending money to a Chinese firm; they won't cheat you. If they do and get caught, the government chops their heads off. Not like here.
I have a written quote from Exmork for a 15 meter (50 foot) free standing monopole tower for $2378 including ocean shipping to Los Angeles. East coast shipping is just slightly more, and they might ship down the St. Lawrence seaway to a seaport near you. These towers are segmented and telescoped together for shipping. There is a company in Michigan (Trans-overseas Corp in Romulus, Michigan) that will handle all the customs duties and overland shipping for you at very reasonable cost. They will know if the Chinese ship to some seaport in Michigan, like maybe Bay City or Port Huron. I bet they do. I've used Trans-overseas and they do a good job. Pilot86 used them too. That tower I mentioned above is for a 5000 watt turbine. My two Chinese towers were only 40 feet long, but they are so strongly overbuilt that after running the calculations I added another 16 feet to them. I could have added another forty feet, but didn't need to. If you want more information let me know in a personal message or a reply to this post; I don't want to get accused of promoting Chinese products for monetary gain. Contrary to accusations against me in previous posts, I don't particularly love the Chinese, I have no financial arrangements with any Chinese firm, I am not a paid spokesperson, a dealer, or a distributor; just an old guy dying of cancer in beautiful southern Utah, trying to help fellow wind enthusiasts find and purchase reasonable quality products at reasonable prices.
