Firewood shall be maintained neatly stacked, not to exceed 48 inches in height, and shall be located behind the rear plane of the house and within the property lines. It should be located in such a manner to minimize visual impact and in certain cases screening may be required. Stacks larger than two (2) cords require approval for aesthetic reasons.  Stacks longer than 6 feet should be two rows deep at minimum.  Firewood stacks must contain firewood only, no storage of debris. If firewood conforms to these criteria, no application is necessary.
