Chapter 18.34 — INDUSTRIAL ZONE DISTRICTS

§ 18.34.010. Purpose of the industrial zone districts. ¶

The purposes of the individual industrial zone districts are as follows:

Limited manufacturing (M-L) zone district: Intended to accommodate a limited group of business, professional, research and technical manufacturing uses which may have unusual requirements for light, space and air and the operations of which are clean and quiet. The M-L zone district is consistent with the commercial and industrial general plan designations.

Light industrial (M-1) zone district: Intended to be applied where heavy commercial, light industrial and warehousing facilities are necessary for public service and convenience. The M-1 zone district is consistent with the commercial and industrial general plan designations.

General industrial (M-2) zone district: Intended to be applied where general industrial and manufacturing facilities are necessary for public service and convenience. The M-2 zone district is consistent with the industrial general plan designation. (Ord. 1365 § 6 (part), 2014)

§ 18.34.020. Allowable land uses and permit requirements. ¶

Table 18.34.020 identifies the uses of land allowed by each of the industrial zone districts. The last column of the table identifies a section of this title that references additional land use regulations or development standards that are applicable to that use. The applicable permit requirements for each use are established by the letter designations as follows:

"P" Designates a permitted use. New development requires a development plan review which is typically a ministerial staff review process that ensures compliance with all city development standards, as provided in Sec. 18.72.010. Larger projects may trigger a more extensive review.
"ZC" Designates that a zoning clearance is needed, which is a ministerial staff review, as provided in Sec. 18.72.020.
"U" Designates that a use permit is required, as provided in Sec. 18.72.030.
"MU" Minor use permit.
Blank Not an allowable use in that zone district.
