A new charter that changes the dynamic of Gainesville City Council awaits the signature of Gov. Nathan Deal.The new charter, authored by Rep. Carl Rogers, a Republican who lives in the city, passed the Senate, its final legislative hurdle, Tuesday.The passage was praised by Gainesville Mayor Danny Dunagan on Wednesday.If the new charter is signed by the governor, Gainesville could vote on its mayor in November 2013.For decades, the position has been largely ceremonial, rotated every two years among the five members.The new proposal keeps the council’s current election structure intact, calling for the citywide election of five council members from each of the city’s wards, and a continued two-year rotation of mayor pro tempore.But it adds a sixth seat to the council: a mayor elected from any of the five wards.That person, when elected, would have the same powers and duties of other council members, except when it comes to voting.With the new addition, any council action would require the approval of four council members, rather than the current three.The new mayor would be restricted from making motions or seconding motions to approve or deny matters before the council. The mayor also would not vote other than to break a tie or to provide a fourth vote in the case that only three other council members were present at a voting meeting.The mayor also would vote on the appointment of the city’s top officials, including mayor pro tempore, city manager, city attorney, city judge, solicitor and auditor.The change comes nearly four years after city voters approved a referendum on the issue of an elected mayor.
