Aaron Christopherson, absent.Those three words have become increasingly common at Woodland City Council meetings this year, and now it now appears the 23-year-old councilman’s absence will become permanent.Christopherson notified Mayor Chuck Blum during a workshop Monday night that he planned to step down because he was moving to Vancouver, the mayor and City Clerk Mari Ripp said. Christopherson has not submitted his resignation in writing, but his resignation is an item on the council’s draft agenda for its upcoming Monday meeting.“The mayor is expecting it, but we haven’t received anything,” Ripp said Wednesday.Christopherson has missed the previous two regular council meetings with unexcused absences and faces removal from the council should he miss next Monday’s meeting without being excused, city officials said. He has faced such a third-strike removal on two other occasions this year, according to city council minutes.In 2007, Christopherson became the area’s youngest elected official when he won election at age 19. He chose not to seek re-election this fall. Tony Brentin and Marshall Allen are running for Christopherson’s seat in the Nov. 8 general election. It is doubtful the council would appoint a replacement for Christopherson so close to the election, Blum said.An inspection of Christopherson’s attendance record in 2011 suggests he has largely finished his term in absentia. Christopherson has missed 10 of 17 council meetings, with only two of his absences excused. He has also missed eight joint or special meetings, with only one of those excused.
