1. All uses contained herein are listed by number as designated in the Wasatch County land use classification, which is published and maintained by the planning department, and are attached as appendix 1, chapter 16.36 of this title. Classes or groupings of uses permitted in the zone are identified by a four (4) digit number in which the last one or two (2) digits are zeros, and subuses of those categories or groupings will follow that number. (For example, a particular category may be listed as 8100, and a subcategory of 8100 would be 8110 and a subcategory of 8110 would 8111.) This document, available in the planning office, is to be used by the planning office and others to assist in determining similar uses and the intent of this chapter.
