It’s the first major upgrade of the Deschutes County Comprehensive Plan since it was implemented in 1979.   Commissioners will spend part of their afternoon today learning about farmland and natural resource policies as they look at fine-tuning the plan. Planner Terry Payne says a few options are being examined to give farm land owners more choices to make money in this tight economy. “So Agri-tourism is one possibility and commercial energy facilities, alternative energy facilities like solar farms. Maybe putting some regulations in to permit those that would keep the large lot farm land but at the same time allow people to make a living on it.”
