(A) Permitted Principal Uses. The intent of Light Industrial Districts is to provide space for certain commercial and a wide range of industrial uses and structures that are able to meet certain performance standards to protect nearby non-commercial and non-industrial uses from undesirable environmental conditions. Residential and other similar uses are prohibited from this district in order to limit environmental effects associated with certain commercial and industrial uses, irrespective of their meeting performance standards.
(1) The following uses are permitted in an I-1 District. When located less than 100 feet from any R district, any such operations must be enclosed by a fence not less than six feet in height, and an earth embankment or two rows of alternate planted evergreen trees or similar vegetation. Provided that each meets the performance standards for this district set forth below, and provided it is not specifically prohibited.
(a) Manufacturing, processing or assemblies of products, materials, or articles that meet the performance standards for this district, provided that it not specifically prohibit.
(b) Wholesale, storage, and warehouse uses.
(c) Agricultural businesses and supplies;
(d) Livestock exchanges (excluding confinement and feeding facilities)
(2) The following are the Performance Standards for open and enclosed industrial uses.
(a) Physical appearance. All operations shall be carried on within an enclosed building; however, new materials or equipment in operable condition may be stored in the open. Normal daily wastes of an inorganic nature may be stored in containers outside a building provided the containers are screened and not readily visible for the street.
(b) Noise. No operating shall be carried on which involves noise in excess of the normal traffic noise of the adjacent street at the time of the daily peak hour with other city laws.
1. Noise shall be measured at the property line; when the level of noise cannot be determined by observation with the natural senses, a suitable instrument may be used and measurement may include breakdowns into a reasonable number of frequency ranges.
2. All noises shall be muffled so as not to be objectionable due to intermittence, beat frequency, or shrillness.
(c) Sewage and liquid wastes - All sewage waste must be in compliance with Federal and State Regulations and with the local Sewer Use Ordinance 1995-3 and all its amendments.
(d) Air contaminants - Shall meet all federal and State Air Emission Regulations.
1. Due to the fact that the possibilities of air contamination cannot reasonably be comprehensively covered in this section, there shall be applied the general rule that there shall not be discharged from any sources whatsoever quantities of air contaminants or other material in such a quantity as to cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public in general; to endanger the comfort, repose, health, or safety of any considerable number of persons or to the public in general; or to cause or have a natural tendency to cause injury or damage to business, vegetation, or property.
(e) Odor. The emissions of odors that are generally agreed to be obnoxious to any considerable number of persons, shall be prohibited.
1. Observations of odor shall be made at the property line of the establishment causing the odor.
2. As a guide to classification of odor, it shall be deemed that strong odors of putrefaction and fermentation tend to be obnoxious and that odors associated with baking shall not normally be considered obnoxious within the meaning of this chapter.
(f) Gasses. The gasses sulfur dioxide and hydrogen sulfide shall not exceed five parts per million. All nitrous fumes shall not exceed one part per million. Measurements shall be taken at the property line of the particular establishment involved.
(g) Glare and Heat. All glares, such as welding arcs and open furnaces, shall be shielded so that they shall not be visible from the property line. No heat from furnaces or processing equipment shall be sensed at the property line to the extent of raising the temperature of air or materials more than 5 degrees F.
(h) Vibration. All machines, including punch presses and stamping machines, shall be mounted so as to minimize vibration; in no case shall vibration exceed a displacement of 3/1000 of an inch measured at the property line.
(B) Permitted Special Exceptions. After the provisions of this chapter relating to special exceptions have been fulfilled, the Board of Zoning Appeals may permit, as special exceptions in Light Industrial Districts, any use that is consistent with the intent of this district and any use that is consistent with the intent of the B-3 Heavy Commercial District which is not prohibited.
(1) Junk, salvage, auto wrecking, and similar operations shall be shielded from the view from streets and from adjacent properties in another district by means of a sturdy, sight-obscuring, eight-foot high fence in good repair and two rows of alternate planted evergreen trees or like vegetation;

The following are the minimum requirements for buildings or structures within industrial districts;
