Section 40.230.080

40.230.080 INDUSTRIAL DISTRICTS (ML, MH, IR)

A. Purpose.

The industrial districts (MH, ML, IR) provide for a wide range of industrial and manufacturing uses including manufacturing, assembly, fabrication, processing, and related research and development; mineral and resource extraction and processing; bulk handling and storage (warehousing); and truck, marine, and rail distribution. The regulations in this section are intended to establish appropriate development and performance standards for industrial activities with the greatest potential for adverse impacts to minimize the presence of nuisance factors and hazards. The regulations in this section are intended to protect the industrial land base for industrial economic development and employment opportunities by limiting residential, institutional, commercial, office and other non-industrial uses to those necessary for the convenience/support of industrial activities. The regulations in this section also apply to industrial lands outside the urban growth areas.

1. Light Industrial District (ML). The light industrial district is intended to provide for those less-intensive industrial uses which produce little noise, odor and pollution. It also provides for resource-based uses and service uses that are deemed compatible with light industrial uses.

2. Heavy Industrial District (MH). The heavy industrial district is intended to preserve, enhance and create areas containing industrial and manufacturing activities which are potentially incompatible with most other uses, and is appropriate for areas which have extensive shipping facilities.

3. Railroad Industrial District (IR). The railroad industrial district is intended to provide for those industrial uses that are most suited for and can take advantage of locations along rail lines within the county.

(Amended: Ord. 2009-05-11)

B. Uses.

The uses set out in Table 40.230.080-1 are examples of uses allowable in the industrial zone districts. The appropriate review authority is mandatory.

“P” – Uses allowed subject to approval of applicable permits.

“C” – Conditional uses which may be permitted, subject to the approval of a conditional use permit as set forth in Section 40.520.030.

“X” – Uses specifically prohibited.

The following list of permitted uses is based on the North American Industrial Classification System (NAICS). NAICS is organized in a hierarchical structure much like the existing SIC (Standard Industrial Classification). NAICS industries are identified by a six (6) digit code, in contrast to the four (4) digit SIC code. The longer code accommodates the larger number of sectors and allows more flexibility in designating subsectors. The use of NAICS codes for permitted uses refers only to the use of a particular site, rather than the type of industry involved.

• The first two (2) digits designate a major economic sector (formerly division), such as agriculture or manufacturing.

• The third digit designates an economic subsector (formerly major group), such as crop production or apparel manufacturing.

• The fourth digit designates an industry group, such as grain and oil seed farming or fiber, yarn and thread mills.

• The fifth digit designates the NAICS industry, such as wheat farming or broadwoven fabric mills.

Retail uses are marked with a “1” in Table 40.230.080-1 below. See the footnotes at the end of the table for an explanation of permitted development.
