The purpose of the I-2, Heavy Industrial District is to accommodate industrial, wholesale, warehouse, and storage activities, and industrial operations whose external physical effects are less restricted and require greater separation from surrounding districts to eliminate potentially negative impacts. This district is structured to permit the manufacturing, compounding, procession, packaging, assembly, and/or treatment of raw material for shipment in bulk form, for use in an industrial operation at another location, subject to performance standards identified in this Ordinance.
