Allow landowners to sever…

Allow landowners to sever property on there property that is zoned prime ag area, however they have a section of property that is absolutely not in anyway farm land. We have a 95 acres completely zoned prime ag area. There is one section of the farm that is a scrubby wooded area, its on a hill side with a ravine at the bottom. A neighbours home is directly beside the lot. We have been over 3years trying to get this severed for our son to build a home. THREE YEARS, and in this time frame other have been granted severances in current working farm fields, only to turn around and sell the property for profit. Township keeps saying we need to look at a secondary residence. So we can build a home on this lot, but it can not be severed......to save farm land?? Tell me how this makes sense. AND, tell me how our son could ever get a mortgage to build a home on land he does not own? No bank would even talk to him about taking such a risk. And he puts himself in a position of loosing the home should the farm ever be sold. SOMEONE PLEASE USE SOME COMMON SENSE, the rural townships need to have the authority to allow severances in situations like ours, cause I am sure we are not the only ones.
