I'm struggling over finding the right language to put into my code to handle this problem. If anyone has ideas, throw it out there, my brain is too dead to think today.
This is for a rural county where the code for lot sizes in an agricultural zone is 200' frontage, width, and depth along with a 3 acre minimum lot size.
Most people just cut out a corner of their farm and can only make one or two lots like the picture below. I'm trying to find a way to regulate splitting that house in the middle without requiring 200' frontage and width straight back.
The idea is to let the farmer sell the house, but keep farming the land. 200' frontage and width would cut out about 4 acres of farmland in most of my cases.
I'm considering allowing flag lots, but only for existing houses, not new lots.
I just think this will get abused somehow with lots tucked into the flag lot where the entrance to both lots starts getting to close for the Road Dept. and it just ate the farm land we were trying to save.

Right now the options I have are
1. Screw you guys and stick with the 200' frontage for everyone
2. Instead of regulating frontage, regulate drive access since that seems to be the problem - except that all the people who have dones this for years will be screwed.
3. Only allow the 50' frontage option for existing houses that are more than X feet from the road and for the purpose of saving farm land (this would be a planning commission vote and maybe require a deed restriction)
4. Allow the Board of Zoning Appeals to make an exception for frontage beyond the 30% they are allowed, but that's a 75% exception (I don't think it would fly)

Any thoughts? Or you can just tell me I'm out of luck, I understand.
