Industrial districts are intended for the location of structures, uses, and activities that produce goods from extracted and raw materials or from recyclable or previously prepared materials, including the design, storage, distribution, and handling of these products and the materials from which they are produced. Research and technology uses and services are appropriate in industrial districts along with support offices and services.

A.

I1: Light industrial. The light industrial zone is intended to accommodate a variety of business, warehouse, and light industrial uses related to wholesale plus other business and light industries. Low intensity light industrial development can be compatible with adjacent commercial zones. I1 zoning should provide locations directly accessible to arterial and other transportation systems that can conveniently serve the business and industrial centers of the city and county.

B.

I2: Heavy industrial. This district accommodates larger or more intensive manufacturing and distribution facilities and related support services. Heavy industrial sites will have ready access to necessary utilities and at least two (2) or more major transportation routes. Characteristics of the uses in this district may include outdoor storage areas, truck traffic, production of goods from raw materials, and multiple worker shifts. Some may involve large structures on large parcels.
