When an application is made for a use category or use type that is not specifically listed in Table 4-1, the Community Development Director shall be authorized to make a determination as to whether the proposed use category or use type is included within the definition of an existing use category or use type in Chapter 11, based on the characteristics of use types and categories set forth in Chapter 11. Any such determination shall be in writing, and a copy of the decision shall be given to the party proposing the use. If the Community Development Director determines that the proposed use type or use category is not included in any existing use type or category, then the proposed use may only be allowed if this Land Use Code is amended to include such use type or category in Table 4-1 and to include a definition of the use type or category in Chapter 11.
