§ 159.20  (A) AGRICULTURAL DISTRICT.
   (A)   Purpose.
      (1)   The Agricultural District is to be used to promote orderly, timely, economic growth and to recognize current land use conditions. The district is a reserved area in which the future growth of the city might occur. It is the intent of this district that agricultural land be held in that use for as long as is practical and reasonable. This zoning is suitable for areas where development is premature because of a lack of utilities, capacity or service, or where the ultimate land use has not been determined.
      (2)   The zone is also to be used:
         (a)   To protect those areas that are unsuitable for development because of physical problems or potential health or safety hazards such as flooding. The usage of the land would be permanently restricted to low-intensity agricultural uses until such time as the property is proven to be suitable for development and is rezoned; and
         (b)   To provide a permanent greenbelt to preserve natural areas or open space buffer around uses that might otherwise be objectionable or pose environmental or health hazards.
   (B)   Permitted uses.
      (1)   Farming, ranching, related activities, and one detached single-family dwelling per lot.
      (2)   Home occupations;
      (3)   Municipality owned or controlled facilities, utilities, and uses;
      (4)   Temporary concrete batching plants limited to the period of construction, upon approval of location and operation by the Building Official;
      (5)   Wind energy systems on lots greater than ten acres in size subject to all terms and conditions of § 159.50; and
      (6)   A single open landscape structure on the same lot as an accessory to a residential use and used as a trellis, arbor, pergola, gazebo, or outdoor kitchen that does not exceed 350 square feet in area and 15 feet in height.
      (7)   Accessory buildings and dwelling units. The maximum combined floor area, maximum size for a single building, maximum wall height, and number of accessory buildings per lot/tract permitted shall be based on the lot/tract size. Such regulations shall conform to the following criteria in the table below:
 
(a) Lot/Tract Size
