Chapter 18. General Zoning Ordinance

Sec. 18-59. Industrial Land Uses

(1) Light Industrial: Facilities where all operations, with the exception of loading, are conducted entirely within an enclosed building. Such land uses are not associated with nuisances such as odor, noise, heat, vibration, and radiation which are detectable at the property line, and do not pose a significant safety hazard (such as danger of explosion). Light Industrial land uses may include ancillary office space and may conduct indoor sales as an accessory use provided that the use complies with the requirements of Section 18-65(17).

Regulations:

(a) All activities, but excluding loading and unloading, shall be conducted entirely within the confines of a building.

(b) Minimum required parking: One space per each employee on the largest work shift.

(2) Heavy Industrial: Industrial activities that may be wholly or partially located outside of an enclosed building; may have the potential to create certain nuisances which are detectable at the property line; and may involve materials which pose a significant safety hazard. Examples include, but are not limited to: meat product producers; paper, pulp or paperboard producers; chemical and allied product producers (except drug producers) including poison or fertilizer producers; petroleum and coal product producers; asphalt, concrete or cement producers; tanneries; stone, clay, or glass product producers; primary metal producers; heavy machinery producers; electrical distribution equipment producers; electrical industrial apparatus producers; transportation vehicle producers; commercial sanitary sewage treatment plants; railroad switching yards; recycling facilities not involving the on‑site storage of salvage materials; and large-scale alcoholic beverage producers exceeding the production limits in Chapter 125, Wisconsin Statutes. Heavy Industrial land uses may include ancillary office space.

Regulations:

(a) All activities, including ancillary office space but excluding loading and unloading, shall be conducted entirely within the confines of a building.

(b) All outdoor activity areas shall be surrounded by a bufferyard with a minimum opacity of 1.00.

(c) All outdoor activity areas shall be located a minimum of 100 feet from residentially zoned property.

(d) No equipment or materials shall be stacked or otherwise stored so as to be visible over bufferyard screening elements.

(e) In no instance shall a Heavy Industrial land use exceed the performance standards listed in Article VII.

(f) Minimum required parking: One space per each employee on the largest work shift.

(3) Research, Development, and Related Manufacturing: Research and development and the manufacturing of items for testing and for sale that are associated with the research and development conducted on-site. All operations, with the exception of loading, shall be conducted entirely within an enclosed building. Such land uses shall not be associated with or result in nuisances such as odor, noise, heat, vibration, and radiation which are detectable at the property line, and do not pose a significant safety hazard (such as danger of explosion).

Regulations:

(a) All activities, except loading and unloading, shall be conducted entirely within the confines of a building.

(b) Minimum required parking: One space per each employee on the largest work shift.

(4) Production Greenhouse: Any business whose principal activity is the growing and wholesaling of plants or plant byproducts (not including fruits and vegetables) that are either grown or stored within an enclosed building or structure constructed chiefly of glass or glasslike material, cloth, or other permanent material. Such uses also often involve the seasonal display of plants and related products outdoors.

Regulations:

(a) In no event shall the display of items reduce or inhibit the use or number of parking stalls provided on the property below the requirement established by the provisions of (f), below. If the number of provided parking stalls on the property is already less than the requirement, such display area shall not further reduce the number of parking stalls already present.

(b) Storage and/or Outdoor Display areas shall be separated from any vehicular parking or circulation area by a minimum of 10 feet. This separation shall be clearly distinguished by a physical feature or barrier such as a greenway, curb, fence, or line of planters, or by a clearly marked paved area.

(c) Signs, screening, enclosures, landscaping, or materials being displayed shall not interfere in any manner with either on‑site or off-site traffic visibility, including potential traffic/traffic and traffic/pedestrian conflicts.

(d) The facility shall be surrounded by a bufferyard with a minimum opacity of 0.60 along all borders of Outdoor Display areas abutting residentially zoned property.

(e) Minimum required parking: One space per 350 square feet of gross floor area.

(5) Indoor Food Production: Any business whose principal activity is the production and wholesaling of plants or plant byproducts (including fruits and vegetables) that are grown on-site within an enclosed building or structure constructed chiefly of glass or glasslike material, cloth, or other permanent material. Such uses also often involve the seasonal display of plants and related products outdoors. Indoor Food Production also includes the farming of aquatic organisms (plants and animals) under controlled conditions, and which is located entirely within an enclosed building and utilizes recirculating (closed) system technology. Such operations may also incorporate aquaponics, which is the symbiotic cultivation of plants and aquatic organisms in a recirculating system.

Regulations:

(a) All outdoor storage areas shall be completely enclosed by any permitted combination of buildings, structures, walls, and/or fencing. Such walls and fencing shall be a minimum of 8 feet in height and shall be designed to completely screen all stored materials or products from view of non-industrialized areas at an elevation of 5 feet above the grade of all abutting properties and rights-of-way. Said walls or fencing shall be screened from residentially zoned property by a bufferyard with a minimum opacity of 0.80.

(b) Storage and/or Outdoor Display areas shall be separated from any vehicular parking or circulation area by a minimum of 10 feet. This separation shall be clearly distinguished by a physical feature or barrier such as a greenway, curb, fence, or line of planters, or by a clearly marked paved area.

(c) All outdoor storage areas shall be located no closer to a residentially zoned property than the required minimum setback for buildings on the subject property.

(d) The storage of items shall not be permitted in any landscaping areas, bufferyard areas, or permanently protected green space areas.

(e) In no event shall the storage of items reduce or inhibit the use or number of parking stalls provided on the property below the requirement established by the provisions of (n), below. If the number of provided parking stalls on the property is already less than the requirement, such storage area shall not further reduce the number of parking stalls already present.

(f) Materials being stored shall not interfere in any manner with either on-site or off-site traffic visibility, including potential vehicle/vehicle and vehicle/pedestrian conflicts.

(j) The on-site retail sale of seafood or vegetables shall be considered Incidental Indoor Sales subject to the provisions of Section 18-65(18), provided the area devoted to sales does not exceed 25 percent of the total area of the building(s) within which the operation is located. Retail areas that exceed 25 percent of the total area of the building(s) within which the operation is located shall be considered an indoor sales and service principal land use.
