In creating use zones, the council has considered the characteristics of uses which make them comparable, compatible or similar. The council recognizes that it is not possible to enumerate and classify every use to which land may be devoted, either now or in the future, and that ambiguity may exist with reference to the appropriate and consistent classification of a use. There-fore:
A.
When any known and identifiable use is not listed as a permissible use in any zone; or
B.
When any use has not come into existence by reason of any technical development in the trades, sciences and equipment; or
C.
When any use already listed in the zone which, because of any process, equipment or materials used, possesses different performance standards than those which are usually associated with the uses in the zone as presently classified and which, therefore, makes it reasonable that such a use should be placed in the more restrictive zone, it shall be the responsibility and duty of the planning commission to ascertain all pertinent facts relating to any such use and make what it deems to be appropriate recommendations for zoning. Any proceedings under this chapter shall be processed as an amendment.
