Temporary sales of Christmas trees may be permitted beginning the day after Thanksgiving in November through the month of December in business zones and by nonprofit groups in zones as provided in Section 22-5 of these regulations. Such sales shall be in accordance with a permit issued by the Zoning Officer. No permit shall be issued unless adequate off-street stopping space or maneuvering space for vehicles of customers can be provided and it can be demonstrated that the temporary use will not interfere with others on the site. Each such use shall be permitted to have one freestanding sign, no larger than 12 square feet in area, no closer to any property line than 10 feet, and exceeding eight feet in height. Such signs shall be temporary and shall be removed from the property on which the sales are being conducted no later than December 31.
