One of my site acquisition agents reports an interesting conversation with a Twp zoning administrator. (Hey, I was one once!)
WCF (cell tower) is permitted by right on Twp property. The two choices are a park on a major waterfront (I can hear the public comments now), and a postage stamp that won't meet setbacks.
The ZA recommends obtaining a variance to allow a WCF in the Ag district (larger parcels, can meet setbacks) with a SUP.
In my experience, it's customary to request or issue a variance on a specific site. And if the entire zoning district needs an amendment, that should be done rather than allow a wireless company to re-write the ordinance.
Thanks for any comments. This situation is in the grand and glorious state of Michigan.
(I might add something to the career advice thread regarding mail-order planning degrees)
