The letter asks residents to support an emergency review of the Akron charter that allows 2 percent of the registered voters to trigger such recall elections.
The letter indirectly supports Akron Mayor Don Plusquellic, who is facing a recall vote.
Hudson Mayor Bill Currin, who helped organize the effort, said the main aim of the letter was to focus on the recall process.
The letter -- published Friday in the Beacon Journal -- argues that a mayoral recall "is not an appropriate way to resolve disagreements regarding policy decisions."
The letter was signed by the mayors of Hudson, Reminderville, New Franklin, Peninsula, Stow, Barberton, Boston Heights, Tallmadge, Lakemore, Norton, Macedonia, Richfield, Green, Twinsburg and Fairlawn.
