BANGOR, Maine — Bangor’s nine-member City Council will have at least two new councilors after November’s elections.

Three seats are up for grabs, but only Councilor Gibran Graham has decided to run for re-election. He’s seeking his second term.

Councilors Nelson Durgin and Josh Plourde, whose three-year terms expire, won’t be running again.

“Basically, I’ve gotten to the point where I need to step back a little,” Durgin said Wednesday. “I think it’s time to let the younger people take over.”

The city’s charter precludes a councilor from serving more than three consecutive terms. Durgin, a retired major general who headed the Maine National Guard, is wrapping up his second term but said his age factored into his decision to not run again. He would be turning 80 before his third term expired, he said. Durgin served as council chairman in 2012. Durgin ran for the council in 2010 after retiring from the Phillips-Strickland House, a Bangor assisted-living facility.

Plourde, communications manager for the University of Maine’s Advanced Structures and Composites Center, said he isn’t running again because he’s taking time to work on a book and to be more involved in Bangor’s Beth El Congregation.

“It’s been a tremendous learning opportunity for me, and I think we’ve made some good contributions,” Plourde said of his time on the council. “But I want to focus on community building outside of Harlow Street, and also open an opportunity for others.”

Wednesday was the first day that people interested in running for the City Council and school committee could take out paperwork necessary to pursue seats in city government.

Lisa Goodwin, Bangor’s city clerk, said Wednesday afternoon that Graham and Dan Tremble had taken out papers for the City Council race.

Tremble is a local businessman and Penobscot County treasurer who served two consecutive terms on the council in the early 2000s, including a year as chairman.

Graham is co-owner of Coespace, a downtown events venue, and manager of Briar Patch, a downtown book and toy store. He’s active in Bangor’s arts community and organizes community events, including the recent Central Street party celebrating the release of the newest Harry Potter book.

The earliest candidates can turn in completed paperwork is Aug. 22, Goodwin said.
