[In an M-2 general industrial district, only the following uses of property shall be permitted:]

Any use permitted in M-1 district; all uses not specifically prohibited by this or any other city ordinance; provided, however, that no building or structure shall be erected, reconstructed, or structurally altered for residential use except for dwelling quarters for watchmen and caretakers.

New dwellings; churches; schools offering general education courses; libraries [are prohibited].

Other uses may be permitted, provided they are not in conflict with any other ordinance, and provided further, that such uses are approved by the city council and subject to such safeguards as the council may establish after receiving a report and recommendation by the planning commission. These conditional uses are:

Acid manufacturers.

Airports, landing fields, landing strips for aircraft, and hangars with repair facilities.

Cement, lime, gypsum, or plaster of paris manufacturers.

Distillation of bones plants.

Explosives, manufactured or stored.

Fat rendering plants.

Fertilizer manufacturers.

Garbage, offal, dead animal reduction plants, or dumping yards.

Gas manufacturers.

Glue manufacturers.

Petroleum or its products, refineries.

Smelters of tin, copper, zinc, or iron ores.

Stockyards or slaughterhouses.

Wholesale gasoline storage yards.

Any other similar uses which would be objectionable or obnoxious because of danger from explosion or creation of smoke, dust, fumes, odors, gas, noise and vibrations and similar conditions.

In approving the above-listed uses, the council will be guided by the following standards:

1.

Any use which emits odors, gas, or dust which is unpleasant, obnoxious, or injurious to health, will be required to design and construct necessary buildings, enclosures, filtering systems, or other facilities necessary for eliminating or reducing the intensity or concentration of such odors and/or dust to a level which will not be detrimental to zoned residential districts close to the particular use. In determining what is "detrimental," inspection of similar facilities operating in other locations with particular attention to the appearance and condition of adjacent residential area will assist the council in making a determination. Study of court decisions involving cases where damage has been claimed by residents living near such odor- or dust-emitting plants may be used as an instrument to interpret this paragraph.

2.

Proper provision must be made for storage of raw materials and wastes to prevent unsanitary conditions or the breeding of flies, insects, and rodents. A safeguard against such conditions may be the requirement to store such materials in tight buildings or bins.

3.

If the industrial operation requires aboveground storage of explosive materials, the industry may be required to acquire sufficient land area surrounding the plant to minimize danger to people and property adjacent to the industry. A similar requirement may be established for an industry engaging in an activity which creates noise or vibrations.

No building shall exceed 100 feet in height. However, those buildings in an M industrial district which adjoin or abut a residence district shall not exceed 45 feet in height, unless set back from all lot lines one foot for each foot of additional height above 45 feet.

[In M-2 general industrial districts, the following area regulations shall apply:]

Yards.

1.

Whenever an M-2 industrial district abuts on a residential district which requires front, side, and rear yards, these requirements shall apply for the entire block in which the abutment occurs or 150 feet when no block exists and [the] requirements of article 2, section 2.14 shall also apply.

2.

Front yard: None except where it abuts on a residential district.

3.

Side yard: None except where it abuts on a residential district, except in no case where a building side yard is provided shall it be less than three feet.

4.

Rear yard: None except where it abuts on a residential district.

Lot size. None.

Off-street parking regulations as provided for under article 4 [of this appendix].

Loading zone requirements shall be as provided for under article 4 [of this appendix].
