Liz Milwe will return to the Representative Town Meeting as a District 1 representative, filling the vacancy created when Don Bergmann resigned from the seat last month.

The announcement was made Tuesday by RTM Moderator Eileen Lavigne Flug, following a caucus of three remaining District 1 members to select a replacement.

"Liz previously served on the RTM for three terms, from 2005 to 2011 when she did not seek re-election," Flug said in a news release. "I served with Liz during the four years that she previously served and I am looking forward to serving with her again."

Milwe will serve the remainder of Bergmann's term, which runs until November 2015.

Milwe, who lives in the Saugatuck Shores area, is a lifelong Westport resident.

In her earlier tenure on the legislative body, Milwe was one of the four co-sponsors (then as a District 4 representative) of Westport's plastic bag ban, the first local prohibition on merchants using plastic bags on the East Coast, said Flug.

In mid-May, Bergmann resigned the seat he had held since November 2011. He was known for speaking out regularly at public meetings.

"I wish to thank Don Bergmann for his dedicated public service to the town of Westport as an RTM member," Flug said when he stepped down. "It is a pleasure working with Don and I am certain he will continue to be involved and contribute to town affairs."
