Clark County Commissioner David Madore on Wednesday suggested cutting off county funding to the Southwest Washington Regional Transportation Council, citing a “continuous track record of the RTC dismissing the leadership of the county.”In an email to RTC Executive Director Matt Ransom, Madore said he supports a policy to “significantly reduce” the dues that the county pays to the regional planning agency in the coming year. A total of 21 jurisdictions pay membership dues to RTC each year. Clark County pays the largest amount of any agency, slated to be $36,300 in 2015. That’s about 2 percent of RTC’s overall budget of $1.7 million next year.It’s unclear what impact cutting those dues would have on the county’s standing as an RTC member. Ransom could not be reached for comment.Madore didn’t cite specifics in his notification to Ransom, and couldn’t immediately be reached for comment. But during last week’s RTC board meeting, Clark County was passed over for both the chair and vice chair positions on the board.
