The purpose and intent of the I-1 zoning district is to provide for the heavy commercial, manufacturing and other industrial needs of the city in appropriate locations. However, activities which produce noise, smoke, dust, vibration, glare or similarly objectionable nuisances or use fissionable materials or their wastes, shall be regulated in this as well as other districts. Residential uses are expressly prohibited in this zone.

Permitted and conditional uses allowed in the I-1 district are in Section 17.0.141. All conditional uses must comply with [Section] 17.0.181 Uses.

Some permitted uses shall comply with specific standards as referenced in this article. All uses shall comply with Standards of General Applicability 17.15.

The following standards shall apply to development in the M-I zoning district:
