Voters in Ketchum will soon be able to decide on whether or not they would like a new form of city government.  The Idaho Mountain Express reports that The Ketchum City Clerk's office notified Anne Corrock on Friday that the initiative petition she spearheaded to adopt the council-manager form of government has the required number of signatures. That means the issue can be put to voters.  In a letter to Corrock dated August 5 th, City Treasurer/Clerk Sandra Cady said the required number of signatures was 213, and the petition contained 233 certified signatures.  Per Idaho code, Ketchum Mayor Randy Hall must establish a date for a special election on the issue. The proclamation will be put on the City Council's August 15th agenda.
