A.   I-1 Zone: The objective in establishing the light industrial (I-1) zone is to provide appropriate space for the development and operation of warehousing, light manufacturing, fabrication of goods, wholesaling, service and other similar commercial establishments, which are necessary and beneficial to the area economy, in locations where uses are compatible with one another. The intent is that these activities may be established and operate without creating smoke, gas, odor, dust, sound, vibration or lighting to any degree which would be offensive to residents of the city or surrounding areas.

   B.   I-2 Zone: The objective in establishing the heavy industrial (I-2) zone is to provide appropriate space for the development and operation of warehousing, light and heavy manufacturing, fabrication of goods, wholesaling, service and other similar commercial establishments, which are necessary and beneficial to the area economy, in locations where uses are compatible with one another. The intent is that these activities may be established and operate with the minimal creation of smoke, gas, odor, dust, sound, vibration or lighting, and due to their location would not be significantly offensive to residents of the city or surrounding areas.

   C.   BP Zone: The objective in establishing the business park (BP) zone is to provide appropriate space for the development and operation of research and development, light manufacturing, and the fabrication of goods in a controlled and aesthetically desirable environment. The intent is that these activities may be established and operate without creating smoke, gas, odor, dust, sound, vibration or lighting to any degree which would be offensive to residents of the city or surrounding areas. The zone is characterized by attractively designed buildings, landscape areas and parking lots in a campuslike setting. (Ord. 2007-05, 2-28-2007)

   B.   Storage; Fencing: In the I-1 and I-2 zones, all storage, except passenger vehicles in running order, shall be stored within an enclosed building or within an enclosure surrounded by a solid decorative fence or wall (chainlink fencing with slats is not considered a solid fence or wall for the purposes set forth in this chapter) of not less than six feet (6') in height when adjacent to an agricultural or residential zone boundary. The materials and colors of the fence or wall shall be compatible with their associated buildings. Under conditional use permit review, the city shall determine if a solid fence or wall is required when adjacent to any other zone boundary.

All uses which will maintain outdoor storage of any materials shall keep such materials in an orderly manner and said products shall not project above the fence or wall within twenty feet (20') from any residential or agricultural zone boundary. In order to protect public safety, if there are any other codes, ordinances, laws or other applicable regulations requiring greater separation of stored materials or processes from adjoining uses, the greater distance of required setback shall prevail. If products stored exceed six feet (6') in height, those products shall be set back from an agricultural or residential zone boundary according to the following chart:
