The following findings of fact made:

12.11.

Residential, Commercial, Industrial or Agricultural Classification Inadequate. Within Daviess County there are a number of land activities that have characteristics of operations that do not readily permit classification in the usual residential, commercial, industrial, or agricultural districts. However, they are necessary to the livability or economic health of the community or are of such character that their specific control is necessary.

12.12.

Conditional Use Inadequate. Many of these activities are permitted as conditional uses within particular residential, commercial, industrial, or agricultural zones. However, the need for specifically enumerated performance standards and site locational standards make inclusion as a conditional use in a particular zone inadequate, since the restrictions in each zone must be applied equally to all uses within the zone, and the conditions which the Board of Adjustment may attach are not enumerated in such a manner as to avoid inconsistent and unequal treatment of similar activities.
