Dublin San Ramon Services District board member Dawn Benson resigned from the board this week to apply for an employment position within the district, which provides wastewater services to Pleasanton.
Benson is applying for a job as the district's executive services supervisor, and she said it would be inappropriate for her to continue as a part of the district's governing board while she pursues a job within the district.
She announced her "abrupt and difficult decision" to resign in a letter to her fellow board members Wednesday.
"This promotional opportunity doesn't come up very often in the special district agency network, and I just can't pass this one up," she said wrote in her letter. "This decision is probably one of the most difficult for me to make, as I sincerely enjoy being on the Board and value each of you dearly."
Benson was elected to the board in 2010, re-elected in 2014 and served as board president in 2013.
"We thank Dawn for all her contributions and her deep love of serving this community. We'll miss her," board president Ed Duarte said in a statement. "As a District committed to transparency, we will keep the public informed of the process we use to fill this vacancy."
The board will decide at the next public meeting Sept. 1 what process to use to fill Benson's seat.
The board can choose to appoint a new board member whose term will run through 2018, hold a special election for a board member or do nothing, Stephenson said. If the board chooses to do nothing, the Alameda County Board of Supervisors can choose to appoint a board member or hold a special election.
The board is comprised of five members who are publicly elected to four-year terms. Registered voters who live within the DSRSD jurisdictional boundaries are eligible to vote for board members, according to the Alameda County Registrar of Voters office.
The job of executive services supervisor, for which Benson is applying, is a mid-management position. Duties include overseeing administrative staff who prepare budgets and minutes for DSRSD board meetings, meetings of a joint authority board that manages recycled water in San Ramon and meetings of a board that manages and oversees a pipeline that removes sewage from the valley area, spokeswoman Sue Stephenson said.
A candidate is expected to be chosen for the role by October from the many applications that have been received, she said.
The next DSRSD board meeting is scheduled for 6 p.m. Sept. 1 at the district office, 7051 Dublin Blvd.
