PORTLAND — Nomination papers for the Nov. 3 city elections will be available Monday, June 29.

Voters this fall will elect three city councilors, three School Committee members and two Peaks Island Council members. There will also be a one-year term available on the Portland Water District because Trustee Matt Sinclair moved out of town, according to City Clerk Linda Cohen.

District 1 Councilor Kevin Donoghue and District 2 Councilor David Marshall will complete their first terms on the council in November. Both have announced they will seek re-election.

At-large Councilor Nicholas Mavodones will wrap up his third term and is expected to run for a fourth. Mavodones served as mayor in 2007 and 2000.

District 1 includes the peninsula east of High Street, and the islands. Donoghue, a Munjoy Hill resident, defeated incumbent Councilor Will Gorham in 2006 for the hill seat. Gorham was considering attempting to reclaim the seat this fall, but on Monday said he has decided not to run

Marshall represents the peninsula west of High Street, including the West End and Parkside. Along with Donoghue, he was among the first Green Independent Party members elected to the officially non-partisan council.

School Committee representative Rebecca Minnick is not seeking re-election, and District 1 resident Jenna Vendil said this week she will run for the seat. Vendil has helped orchestrate political campaigns for the past few years and is a field organizer for the League of Young Voters.

District 2 School Committee member Robert O’Brien said he is “uncommitted” at this time about running again. O’Brien, a West End resident, was recently elected to the Charter Commission. He is finishing up his first term on the School Committee.

At-large School Committee member Sarah Thompson said this week that she will seek re-election. Thompson is also coming to the end of her first, three-year term.

The Peaks Island Council seats that will be in play currently belong to Thomas Bohan and Elizabeth Stout. Both representatives are finishing up two-year terms on the inaugural council.

Nomination papers will be available at the city clerk’s office beginning Monday, June 29. They must be returned by Aug.24. Candidates seeking district seats have to gather 75 signatures from registered voters. At-large candidates have to turn in 300.
