But during her five chances to vote on environmental issues last year, she made the right call four times, the OLCV said.
But the other councilors - George Poling, Gary Pape, Chris Pryor and Jennifer Solomon - voted more wrong than right, according to the OLCV.
The OLCV's review included five environmental-related decisions made by the council in 2005, the last one in July.
Also, the OLCV scorecard included a vote from a council deliberation in 2004 to restart the West Eugene Enterprise Zone.
The OLCV wanted the council to limit the breaks to sites that were already developed or were contaminated.
That decision, the OLCV said, would increase sprawl.
Yet, the OLCV didn't mention the council's vote four months later that reversed that decision.
Lane County commissioners boosted their overall average voting score to 60 percent on 11 key votes, up from 39 percent in the previous rating period, the OLCV said.
Bill Dwyer got a "respectable" 63 percent rating, and Bobby Green rated "poorly," with 36 percent, the OLCV said.
