A. Grouping of Uses. Uses have been grouped into residential, public, and institutional, commercial, office/medical, industrial, and other. To regulate use, categories of uses (“use categories”) have been established. Use categories provide a systematic basis for assigning land uses to appropriate categories or zoning districts with other similar or compatible uses. Use categories classify land uses and activities based on common functional, product or physical characteristics. Characteristics include the type and amount of activity, the characteristics of customers or residents, how goods or services are sold or delivered, and certain site factors.
