If any use is for any reason omitted from the lists of those specified as permissible in each of the various zones herein designated, or if ambiguity arises concerning the appropriate classification of a particular use within the meaning and intent of this title, or if ambiguity exists with reference to matters of height, yard requirements, area requirements or zone boundaries, as set forth herein and as they may pertain to unforeseen circumstances, it shall be the duty of the Planning Commission to ascertain all pertinent facts and set forth its findings and reasons.  If the Planning Commission determines that it is appropriate to resolve the uncertainty by amending the Zoning Code, such recommendation shall be treated the same as a recommendation for a Zoning Code amendment as set forth in Section 18.76.050 of Chapter 18.76 (Zoning Amendments).  (Ord. 5920 § 1 (part); June 8, 2004.)
