The City Clerk shall maintain an index of all Planning Commission and City Council actions on variance applications, showing the applicant’s name, premises location, the variance requested, and whether the application was granted or denied. No new application relating to the same premises and the same relief shall be filed for a period of one year following the Planning Commission’s determination, or the City Council’s determination should there be an appeal, unless such filing is first authorized by the Planning Commission on a showing of substantial change of circumstances. (Ord. 89-1 § 1, 1989.)
