ASTORIA, Ore. -

The city of Astoria's longest-serving mayor, Willis Van Dusen, says he won't run for re-election.

Van Dusen told the Daily Astorian that at 61, he wants to focus on his family soft drink bottling and distribution business.

He has served six terms as mayor, starting in January 1991. He was on the City Council six years before that.

He told the newspaper he got into city government to resist plans to close the landfill and put a garbage transfer station next to his business.

Nearly 30 years later, the city is now ready to close the landfill at the end of 2014, and Van Dusen said he's taking that as a signal that it was time for him to move on.
