By a unanimous vote council members decided to honor the 3 firefighters killed while trying to rescue rafters near the Rock Bottom Dam in 1975.
The plan, which had been held over from the May 15th meeting, passed Monday night with the blessings of family members of those firefighters.
City Council will set aside 3 thousand dollars to pay for the monument.
A monument, members of city council say, is a long time coming.
"I think it's long overdue. It's been 31 years since that tragic accident happened and I think it's very important to mark that spot because of the event, a nationally known event. And also, it brings light that rivers are dangerous," says councilman Chris Papastrat.
Also at Monday night's meeting, council members voted down a proposal to designate June as Gay Pride month in the city, as it did last year.
A number of people showed up to speak for and against the idea during public comment.
It was voted down by a vote of 4 to 4 with one absent.
