Manufacturing and industrial districts included in this zoning ordinance are as follows:

1.

Zone M-1 (Light Manufacturing and Industrial). Zone M-1 provides for the establishment of industrial uses, in an area in close proximity to residential and commercial zones, including the establishment of necessary public service facilities compatible with the requirements of this zone. Standards are provided to control the intensity and development of uses and to limit the performance of activities in the zone to levels permitting no objectionable or obnoxious influences such as smoke, noise, fumes, vibration, radiation, light or glare that might adversely affect the tenants and purposes of this zone or any adjacent zone.

2.

Zone M-2 (Heavy Manufacturing and Industrial). Zone M-2 provides areas where intensive industrial activities may be located, and where the necessary transportation facilities are provided to support movement of the completed products off the industrial sites without causing traffic hazards in the area surrounding the M-2 zones. Since some of the industrial land uses allowed in this zone may cause objectionable levels of smoke, noise, fumes, vibration, radiation, light or glare, performance standards are included to protect neighboring residential areas and other environmentally sensitive land use. Appropriate buffers are provided between the M-2 zones and other zones where possible to minimize potential land use conflicts.

(Ord. No. 2008-04 § 1.)

The manufacturing and industrial zones are established to provide land areas on which a wide variety and complexity of industrial and manufacturing uses and processes may function efficiently and harmoniously. Specialized uses and public service facilities, required or desirable in an area devoted to manufacturing and industrial purposes, are included in the use lists of each zone. The installation and operation of facilities and equipment, necessary and appropriate to the uses of each zone, are regulated with consideration for the special requirements of adjacent zones. Performance standards are prescribed to assist in controlling industrial concentrations, activities and equipment for the mutual benefit of all persons, businesses and uses in and around the zoned area.

(Ord. No. 2008-04 § 1.)

(a)

Permitted uses (uses permitted by right) in the manufacturing and industrial zoning districts are primarily manufacturing, warehouse/distribution, wholesaling, large-scale warehouse retail, automobile dealerships, support commercial services and public uses. Industrial uses are where necessary transportation facilities are provided to support movement of goods and employees.

(b)

Certain uses may not be suitable in every location within manufacturing and industrial zoning districts and therefore require planning director or planning commission discretionary review through the conditional use permit process described in section 27.272 of this zoning ordinance. Table 27.92, Uses by Manufacturing and Industrial Zoning District, lists those uses that are:

1.

Permitted by right;

2.

Permitted as accessory to the manufacturing and industrial use;

3.

Permitted as conditional uses; and

4.

Prohibited in the manufacturing and industrial zoning districts.

(c)

The planning commission may also permit other uses similar to the uses permitted by right in table 27.92 that the planning commission finds to fall within the intent and purpose of these zones, that will not be more obnoxious or materially detrimental to the public welfare or to property in the vicinity of said uses, and which the planning commission finds to be of a comparable nature and of the same class as the uses permitted by right in table 27.92.

(Ord. No. 2008-04 § 1.)

General development standards for the manufacturing and industrial zoning districts are provided in table 27.93. These standards include: (a) minimum lot size; (b) minimum lot width; (c) minimum lot depth; (d) minimum front yard setback; (e) minimum side yard setback; (f) minimum rear yard setback; (g) maximum building coverage; (h) maximum floor area ratio; (i) maximum height; (j) off-street parking; (k) signs; (l) landscape; and (m) accessory buildings. These provisions are intended to provide the minimum acceptable standards for development within the manufacturing and industrial districts necessary to ensure quality development. The development standards are supplemented by special development standards described in article XII of this zoning ordinance.
