Town Administrator Eric Sanderson told the Board of Finance on Oct. 22 that he submitted his resignation to the town on Oct. 15 and that his last day will be Nov. 15.

"I submitted my resignation to the town of Andover on October 15, and my last day is November 15," Sanderson said during the board's Oct. 22 meeting. He said the Board of Selectmen planned a special Friday meeting to consider appointing an interim town manager for three to four months and that he had made contacts to assist that process.

Sanderson said his immediate priority is completing and documenting ongoing grant work so the incoming administrator or interim manager has a clean handoff. He also warned the board that the coming budget season will likely proceed without a permanent town manager and, he said, "probably without the use of a treasurer," creating operational strain.

To limit disruption, Sanderson said he is working with staff, including Chris Harakeli, to prepare the materials the boards and department heads use to submit proposed budgets. He said budget worksheets typically are distributed Dec. 1 and that responsibility for collating submitted budgets will fall to the interim or next town administrator.

Board members asked for copies of a standalone capital-projects spreadsheet Sanderson maintains. He said he would provide the most recent version but cautioned that once the Board of Finance takes ownership and edits the spreadsheet, he stops updating it.

Sanderson also confirmed the treasurer position will be filled through a recruitment process. He said the treasurer's resignation, combined with his own, will leave the town without two long-serving administrative officials during a demanding budget year.

No formal board action was taken on the announcement. The board thanked Sanderson for his service.
