Two Port of Kennewick incumbents will face more than one challenger, forcing a vote in August to decide which top two candidates will square off in November.
Current Commissioner Gene Wagner has decided to run for re-election in District 2. Wagner is the longest-serving member on the three-man board.
Former Benton County Commissioner Leo Bowman and former Kennewick Mayor Tom Moak filed earlier this week for the same position.
In the District 1 race, Danette Layne, a human resources generalist for Richland's Vista Engineering Technology and a Columbia Basin College adjunct instructor, filed for the seat currently held by Don Barnes.
Never miss a local story.
Barnes, who was appointed to the port commission in May 2012, filed earlier this week for the remaining two years of the six-year term.
He is a commercial real estate broker with Coldwell Banker Tomlinson Associated Brokers of Kennewick.
Barry Bush, who became a Benton Public Utility District commissioner last year, filed Friday for the same seat. Bush is a former Energy Northwest employee and also has served as a Marine.
The fourth challenger in the race is the port's former executive director, John Givens. He currently serves on the Kennewick Public Facilities District board.
Port commissioners earn $1,034 monthly, plus $104 for each meeting they attend. A 4 percent raise kicks in next year, increasing commissioners' stipend to $1,075 a month.
District 1 generally includes southeast Richland/Meadow Springs, central and west Kennewick, and Southridge/ Canyon Lakes neighborhoods.
The District 2 seat includes the urban portion of the port area, close to the Columbia River between Interstate 182 to the west and the cable bridge to the east.
