The I-1 industrial district is intended to provide for industrial and manufacturing and warehouse uses in areas separated from other uses and to prevent the intrusion of incompatible uses within the district. The standards set forth herein are designed to minimize or eliminate possible environmental nuisances to adjacent commercial business or residential districts. In I-1 district, no building or land shall be used and no building shall be erected or structurally altered unless otherwise provided in this chapter, except for the following uses:

A.

Permitted Uses. Stormwater management facilities, including but not limited to retention ponds or any stormwater management structures as required by city ordinance or the State of Wisconsin Department of Natural Resources' rules and regulations. Any industrial use involving production, processing, cleaning, servicing, manufacturing, repair or storage of materials, goods or products and including wholesaling, warehousing, transportation and communication facilities except those uses listed under conditional, prohibited and outdoor uses in this section; provided, that such industrial use conforms with all of the performance standards set forth in this chapter.

B.

Uses Permitted With Conditional Use. The following uses may be permitted after due consideration by the plan commission of the impact of such use on the neighboring properties and such other concerns as set forth in Section 20.52.131 of this title as may be appropriate. In granting a conditional use permit the plan commission may impose site design or operating limitations on the use as needed to mitigate any potential negative impacts of the development.

(Ord. 1127 (part), 1998).

A.

Front Yards. On every lot in the industrial district, an open and unobstructed front yard of at least thirty feet shall be required, except for buildings facing collector streets or highways (as designated on the official map), which shall provide an open and unobstructed front yard of thirty-five feet in which no cars may be parked closer than ten feet to the public right-of-way or highway. Front yards shall be provided on each side abutting a public right-of-way.

B.

Side and Rear Yards. Side and rear yards of not less than ten feet shall be provided, except where an industry abuts another zoning district, in which case side and rear yards which abut the district shall not be less than twenty-five feet.

(Ord. 1127 (part), 1998).

(Ord. No. 1437, 1-14-2014)

Hereafter, all new uses, buildings and structures and all existing uses, buildings and structures extended, enlarged or reconstructed with respect to such extended, enlarged or reconstructed portion or portions shall conform to the following environmental performance standards:

A.

Standards of Operation.

1.

Noise. No operation or activity shall transmit any noise exceeding the sound levels listed below during the time periods indicated when measured at or within a property boundary of a land use outside of the industrial district.

* The following noises shall be exempt from the regulations: noises not directly under the control of the property user, noises from temporary construction or maintenance activities during daylight hours, and noises from emergency, safety or warning devices.

2.

Vibration. No operation or activity shall transmit any physical vibration that is above the vibration perception threshold of an individual at or beyond the property line of the source. Vibration perception threshold means the minimum ground or structure-borne vibration motion necessary to cause a normal person to be aware of the vibration by such direct means as, but not limited to, sensation by touch or visual observation of moving objects. Vibrations not directly under the control of the property user and vibrations from temporary construction or maintenance activities shall be exempt from the above standard.

3.

Exterior Lighting. No operation or activity shall produce any intense glare or lighting with the source directly visible beyond the industrial district boundaries. See Chapter 23.025—Exterior Lighting Standards.

4.

Odor. No operation or activity shall emit any substance or combination of substances in such quantities that create an objectionable odor as defined in Chapter NR 429, Wisconsin Administrative Code.

5.

Particulate Emissions. No operation or activity shall emit any particulate matter into the ambient air that exceeds the limitations as established in Chapter NR 415, Wisconsin Administrative Code.

6.

Visible Emissions. No operation or activity shall emit into the ambient air from any direct or portable source any matter that will affect visibility in excess of the limitations established in Chapter NR 431, Wisconsin Administrative Code.

7.

Hazardous Pollutants. No operation or activity shall emit any hazardous substances in such a quantity, concentration or duration as to be injurious to human health or property, and all emissions of hazardous substances shall not exceed the limitations established in Chapter NR 445, Wisconsin Administrative Code.

B.

Administration. Determinations necessary for the administration and enforcement of these standards range from those which can be made by a reasonable person using normal senses and no mechanical equipment, to those requiring substantial technical competence and complex equipment. It is the intent of this title that the methods to be used in determining compliance shall be the responsibility of the zoning officer subject to the following procedures:

1.

Approval of Building Permits. Prior to approving a building permit for any industrial use or any change thereof, the zoning administrator shall have received from the applicant evidence or assurance that the proposed use or changing use will satisfy the air quality, noise, vibration and exterior lighting standards of this title.

2.

Violation of Standards. Whenever the zoning officer has reason to believe the air quality, noise, vibration and exterior lighting standards of this title have been violated, such administrator shall give written notice by certified mail to the person or persons responsible for the alleged violation within thirty days. Failure to reply or correct the alleged violation within thirty days may cause the city to take lawful action to cause correction as provided in this title or to refer the alleged violation to the Wisconsin Department of Natural Resources.
