Shall the City Charter and Municipal Code be amended to change the system of electing City Council members by creating City Council districts, imposing term limits for Council members, and establishing a municipal primary election with runoffs in the fall, to add to the seven-member Council a mayor, who would be elected citywide and would serve as the Council's non-voting chairperson, and to change the process for Council actions by giving the mayor the power to veto Council actions, including emergency actions, which veto could be nullified if a specified number of Council members vote to override it?
