§ 156.077 ML — LIMITED INDUSTRIAL DISTRICTS.
   (A)   Purposes. In addition to the objectives prescribed in § 156.002 of this chapter, the ML Limited industrial Districts are included in the zoning regulations to achieve the following purposes:
      (1)   To reserve appropriately located areas for industrial plants and related activities;
      (2)   To protect areas appropriate for industrial uses from intrusion by dwellings and other inharmonious uses;
      (3)   To protect residential and commercial properties and to protect nuisance-free, nonhazardous industrial uses from noise, odor, insect nuisance, dust, dirt, smoke, vibration, heat and cold, blare, truck and rail traffic, and other objectionable influences, and from fire, explosion, noxious fumes, radiation, and other hazards incidental to certain industrial uses;
      (4)   To provide opportunities for certain types of industrial plants to concentrate in mutually beneficial relationship with each other;
      (5)   To provide adequate space to meet the needs of modern industrial developments, including off-street parking and truck loading areas and landscaping;
      (6)   To provide sufficient open space around industrial structures to protect them from the hazard of fire and to minimize the impact of industrial plants on nearby residential and agricultural districts;
      (7)   To minimize traffic congestion and to avoid the overloading of utilities by preventing the construction of buildings of excessive size in relation to the amount of land around them;
      (8)   To provide locations for industries that can operate in close proximity to commercial and residential uses with minimum mutual adverse impacts; and,
      (9)   To protect light industrial and related uses from nuisances associated with heavy industrial uses.
