Jerry Birdwell was named last Thursday as a Port District 7 commissioner.
Birdwell replaces Larry Maier, who resigned a month ago after serving nine years on the board.
Birdwell will have to file next year and win in the November election to remain on the board.
Maier told commissioners that he was resigning because he wanted to spend more time with his family and do a little ocean fishing.
Birdwell is retired as maintenance director for the Grand Coulee Dam School District.
Birdwell was seated last Thursday on the board.
