INDUSTRIAL DISTRICTS
(a)
The purpose of the TRO Technology-Research-Office District, is to provide an environment where high tech uses and functions such as engineering, design, research and development, computer assisted design, robotics research, prototype development and limited manufacturing, telecommunications, and related storage, warehousing and limited assembly operations associated with principal permitted uses can be located. Advances in industry, technology, and office research facilities, have created uses which are related to industry and office uses, but may not be appropriate or function adequately in a typical industrial or office zoning district. These uses have been identified as high tech uses. The TRO district will be located in a campus-type environment and so situated that uses will be developed without being negatively impacted by elements and conditions which are commonly found in an industrial zoning district.
(b)
The I-1 Light Industrial District is designed so as to primarily accommodate wholesale activities, warehouses, and industrial operations whose external, physical effects are restricted to the area of the district and in no manner affect in a detrimental way any of the surrounding districts. The I-1 district is so structured as to permit, along with any specified uses, the manufacturing, compounding, processing, packaging, assembly, and/or treatment of finished or semi-finished products from previously prepared materials. It is further intended that the processing of raw material for shipment in bulk form, to be used in an industrial operation at another location, not be permitted. Uses in this district must have less of an impact on surrounding uses and generate less truck traffic than the other industrial developments. Limitations regarding the degree of noise, smoke, glare, odor, and vibration are placed upon such uses to preclude any adverse effects upon nearby commercial or residential districts. It is intended that this district act as a transition between heavier industrial uses and residential or commercial areas. The general goals of this use district include, among others, the following specific purposes:
(1)
To provide sufficient space, in appropriate locations, to meet the needs of the city's expected future economy for the types of manufacturing and related uses described herein.
(2)
To protect abutting residential districts by separating them from manufacturing activities, and by prohibiting the use of such industrial areas for new residential development.
(3)
To promote manufacturing development which is free from danger of fire, explosion, toxic and noxious matter, radiation, and other hazards, and from offensive noise, vibration, smoke, odor, and other objectionable influences.
(4)
To promote the most desirable use of land in accordance with a well considered plan. To protect the character and established pattern of adjacent development, and in each area to conserve the value of land and buildings and other structures, and to protect the city's tax revenue.
(c)
The I-2 General Industrial District is designed primarily for manufacturing, assembling, and fabrication activities including large scale or specialized industrial operations, whole external physical effects will be felt to some degree by surrounding districts. The I-2 district is so structured as to permit the manufacturing, processing, and compounding of semi-finished or finished products from raw materials as well as from previously prepared material. The I-2 district is further designed to provide areas within the city where heavy industrial uses can most efficiently utilize major streets, utilities and other infrastructure while minimizing any incompatible aspects with neighboring districts.
(Ord. No. 09-434, § 8.01, 1-20-2009)
Buildings or land shall be not used and buildings shall not be erected except for one or more of the following specified uses, unless otherwise provided for in this ordinance. Land and/or buildings in the districts indicated at the top of Table 8.02 may be used for the purposes denoted by the following abbreviations:
(a)
Permitted use (P). Land and/or buildings in this district may be used for the purposes listed by right.
(b)
Special land use (SLU). The following uses may be permitted by obtaining special land use approval when all applicable requirements in article 13, use requirements, and the standards of section 21.04, review standards, are met.
(c)
Not permitted (—). The use is not permitted in the district.
(d)
Additional requirements. Indicates requirements or conditions applicable to the use.

All lots and buildings shall meet the following dimensional requirements:
TABLE 8.03. INDUSTRIAL DISTRICTS
AREA, HEIGHT AND PLACEMENT REQUIREMENTS
(a)
Building height. Exceptions to building height shall be allowed as provided for in section 14.08, height limit.
(b)
Yards maintained as landscaped open space. All buildings, parking, loading driveways, circulation aisles, and storage areas shall meet the setback requirement. All required yard setbacks that are adjacent to a nonindustrial use shall maintain the minimum yard area as an uninterrupted landscape area.
(c)
Outdoor storage. Outdoor storage shall be screened in accordance with section 16.02, landscaping. Storage areas shall meet the applicable building setback requirements from each lot line.
(d)
Projections into yards. Structures in section 14.11, projections into required yards, shall be permitted to project into required yard setbacks.
(e)
Natural features setback. All structures shall be set back at least 25 feet from all natural features such as drains, regulated wetlands, natural ponds, lakes and streams.
(f)
Front yard setback. The front yard setback shall apply to all yards that adjoin a street including public streets, private streets and interstate highways. Corner lots and double frontage lots shall be considered to have two front yards. All buildings, parking, loading and storage areas shall meet the front yards setback requirement. Detention/retention ponds shall be prohibited in the required front yard setback, unless the city engineer determines there is no reasonable alternative due to existing topography and natural drainage problems. This restriction shall not apply to rain gardens, bio-retention swales, irrigation trench planters and other similar stormwater management alternatives to retention or detention ponds.
(g)
Front yard from local industrial street. The front yard setback may be reduced to 40 feet in the I-1 district and 50 feet in the I-2 district where the frontage is on a local industrial street. A local industrial street shall mean a street that is within an industrial park or a street that is zoned, or master planned for industrial use along its entire length on both sides.
(h)
Loading areas. All loading and unloading shall be provided off-street in the rear yard or interior side yard, and shall in no instance be permitted in a front yard. In those instances where exterior side yards have a common relationship with an industrial district across a public thoroughfare, loading and unloading may take place in said exterior side yard when the setback is equal to at least 50 feet. Loading and unloading areas located in a side yard shall be fully screened from view from a public street. No overhead doors shall be permitted in the front elevation of the building. All nonindustrial districts and uses must be screened from truck loading and unloading activities. The portion of a site used for parking or storage of truck tractors or trailers shall be obscured by a four-foot high landscaped berm and the required fence or wall. The berm shall be landscaped in accordance with section 16.02, landscaping.
(i)
Lot coverage. Maximum lot coverage shall be regulated by two measures:
(1)
The maximum percent of the lot area that can be covered by buildings.
(2)
The maximum percent of the lot area that can be covered by buildings plus other impermeable surfaces, such as pavement or storage yards.
(j)
TRO building height and setbacks. For buildings or portions of buildings that are taller than 65 feet, the minimum required building setbacks from all lot lines shall be increased by one foot for every one foot of building height above 65 feet. For a building or complex of multiple buildings that have variable building heights, the additional setback requirements shall only apply to those buildings or portions of a building taller than 65 feet; allowing for lower portions of buildings at the minimum setback and taller portions of buildings to be stepped-back based upon the increased height.
