Personally, I think electing the Commissioners wold be a good start. Nine Commissioners, one chair, Six year terms, staggered with the election of 2 every two years and three (the chair) in one of them. Half the Commissioners must reside in Western WA and be elected by voters in those counties. The other half in Eastern. The Chair is elected statewide.. I can see that much of the time decisions will be close to 5-4, but each Commissioner will have to defend their votes/positions to the voters.

It will also mean that we will have to find candidates, vote for them, etc. Also means an increase in costs to better pay them. But, it will make the Commission, and by extension the Director, publicly accountable for actions.
