19.46.010 Purpose, applicability.

This chapter provides regulations applicable to development and new land uses in the manufacturing/industrial zoning districts established by Section 19.40.010 (Zoning districts, generally). The purposes of the individual manufacturing/industrial zoning districts and the manner in which they are applied are as follows:

A. ML (Light Manufacturing/Industrial) District. The ML zoning district is applied to areas appropriate for light assembly and manufacturing, wholesaling, warehousing and distribution, agricultural and industrial processing within structures, and support commercial services. The ML zoning district is primarily intended to implement the Industrial Office Mixed Use and the Manufacturing and Warehousing land use designations of the General Plan.

B. MG (General Manufacturing/Industrial) District. The MG zoning district is applied to areas appropriate for a full range of manufacturing, agricultural, and industrial processing, general services and distribution uses, including uses with outdoor equipment and outdoor storage. The MG zoning district is primarily intended to implement the Manufacturing and Warehousing land use designation of the General Plan.

C. IOMU (Industrial Office Mixed Use) District. The IOMU zoning district is applied to areas appropriate for a wide range and combination of light industrial and office development with commercial and other support services integrated vertically and horizontally. Residential uses may be permitted at a density range from 14 to 35 dwelling units per acre. The IOMU zoning district is primarily intended to implement the Industrial Office Mixed Use land use designation of the General Plan.
