The state and Greeneville Board of Mayor and Aldermen have approved changes to the town’s charter.What prompted the charter changes was the cost of elections, and fewer community members coming out to vote during odd-year elections.The Board of Mayor and Aldermen has been changed to a mayor and city council. According to the mayor the odd year elections when there weren’t any national or state elections, only have 300 or 400 people show up to the polls and that would cost $20,000 to hold the election.
