PORTLAND, Maine — Six candidates have qualified to appear on the Nov. 5 election ballot for three City Council seats.

Another six candidates have qualified to be on the ballot for three School Board seats, city election administrator Bud Philbrick said Tuesday morning.

Candidates had until 4:30 p.m. Monday to submit nomination papers, which require a minimum number of signatures from registered voters.

The District 3 council race will be a contest between incumbent Councilor Ed Suslovic of Kenwood Street and Gregory Blouin of Outer Congress Street. Suslovic is seeking his third term representing the district, which includes parts of Deering and Stroudwater. He previously served as an at-large councilor and as a state representative.

Jon Hinck of Pine Street and Wellington Lyons of Danforth Street will vie for the at-large council seat being vacated by Councilor John Anton, who will not seek a third term.

Hinck is a former state representative who failed in a 2012 bid for the Democratic nomination for U.S. Senate. Lyons mounted an unsuccessful campaign last year for the at-large seat held by Councilor Nicholas Mavodones Jr.

Incumbent Councilor Jill Duson of Pennell Avenue will be challenged by Gregory Smaha of Phipps Road in the other at-large council race. Duson has served on the council since 2001.

The race for two at-large School Board seats will be a free-for-all among five candidates who have qualified: Pious Ali, Ralph Carmona, Gene Landry, Frederic Miller and Anna Trevorrow. The seats are being vacated by Jaimey Caron and Kate Snyder, who are both term-limited.

Carmona of North Street, a former mayoral candidate, initially took out nomination papers to run for City Council, but withdrew and instead decided to run for the School Board.

In 2012, Miller of Mayer Road ran as a Republican in state House District 117, but lost by a large margin to Rep. Richard Farnsworth, D-Portland.

Trevorrow of Myrtle Street is a former Charter Commission member who ran unsuccessfully for School Board in 2008 and lost a bid against state Rep. Diane Russell, D-Portland, in 2010.

Incumbent Laurie Davis of Oakdale Street is running unopposed for the District 3 School Board seat.

Incumbent Marjorie Phyfe of Sandpiper Road and Jean Martens of Island Avenue will be on the ballot for the Peaks Island Council, where five seats are open.

Nisha Swinton of Pleasant Street is unopposed for the seat now held by Jamie Willey on the Portland Water District Board of Trustees. She ran unsuccessfully for a seat last year.
