"My wife is retired, and we want to do more things together, and I've served for a long, long time," said Ward, 61.
Monday was also the first day candidates could file papers for the June 3 election, and Ward's announcement ended weeks of speculation about whether he would run.
By the end of the day Monday, five people including incumbent council members Barbara Halliday and Bill Quirk had officially filed papers for the June 3 election. Another incumbent, Councilman Olden Henson, is scheduled to do the same Wednesday.
