(a)   The M-1 Light Industrial-Research District is intended to accommodate certain light industrial, technical research and product development facilities. All such uses permitted in the District are intended to be compatible with one another. Since limited industrial zoned land is available for industrial use in the City of Southgate, it is the City's intent to carefully conserve the land for light industrial and research oriented uses only.

   (b)   In the M-1 Light Industrial-Research District, all uses permitted herein shall be so designed and operated as to produce no discernable glare, heat, odor, vibration or toxic fumes of any kind beyond the walls of the building. Any noise generated by any use permitted in the District shall be no greater than the recorded ambient pressure level of sound generated by land use on surrounding industrial properties in the City of Southgate. The Interstate 75 highway shall be excluded from any such measurements of ambient pressure levels.

   (c)   It is further the intent of the M-1 District that any form of light manufacturing, compounding, processing, packaging or light assembly or treatment shall involve only finished or semi-finished products from previously prepared materials. The light manufacturing, compounding, light assembly or treatment of any product that requires the processing of raw materials for shipment in bulk form for use in an industrial operation at another location is specifically prohibited.

   (d)   Based on the purposes of this District, all uses permitted herein shall:

      (1)   Provide sufficient space in appropriate locations to satisfy expectations pertaining to the City's future economy and employment base for a limited type of light manufacturing and technical research oriented industrial base.

      (2)   Protect abutting residential and non-industrial uses by separating them from industrial uses with sufficient screening buffers and setbacks.

      (3)   Prohibit non-industrial oriented uses from further encroachment into the remaining areas of the City proposed for light industrial and technical research oriented land use.

      (4)   Promote light industrial and technical research oriented land use of the type that will be able to adhere to strict Federal, State and local environmental performance and safety standards.

      (5)   Promote the most desirable use of land in accordance with the land use recommendations of the City's Master Plan Map, thereby protecting and enhancing the character of the established pattern of nearby development, the value of land and the use on it, as well as the industrial tax base of the City.
