Mr. Carlson's term expires in December 2014, and City Clerk Theresa DellaSanta said the council will have the option of calling a special election or appointing a new member. The council will have 60 days after Mr. Carlson resigns to make that decision, she said.
Mr. Carlson now serves as vice mayor, which means the council will have to appoint a colleague to that position once Mr. Carlson steps down. The vice mayor typically is appointed by his colleagues to the mayor's post at the end of the year.
Mr. Carlson was appointed to the council in January 2006 to replace Bill Conwell, who died in office the month before. He successfully stood for election in November 2006, and was re-elected in 2010.
For the last few years, Councilman Carlson has been closely involved with the town's challenge to the high-speed rail project, and is on the town's Rail Committee. He has also been intensely focused on getting the town's financial health on track, and currently serves on the town's Audit and Finance Committee.
At the Wednesday night council meeting, Mr. Carlson said he and his wife, Shirley, were putting their house on the market next week, but that he would continue to serve on the council for a short while longer. He said it's likely his council tenure would end with the fiscal year, which concludes June 30, although if he moves from town before then, he must give up his post at that time.
Mr. Carlson told the Almanac that family-care matters make it likely that he will continue to live on the Peninsula, but that he and his wife are eager to travel, both domestically and overseas.
