The Lake County Vector Control Board of Trustees will hold the hearing at 1:30 p.m. Tuesday, June 30, in the Board of Supervisors Chambers at the Lake County Courthouse, 255 N. Forbes St., Lakeport.
Ballots went out in May for the assessment, which Vector Control officials said they're requesting to help them update facilities such as the district's laboratory and maintain current service levels.
At an average of $13.96 per single family residence, the assessment is projected to bring $500,000 a year into the district, which currently has a $1.3 million annual budget, as Lake County News has reported.
County residents will have the opportunity to ask questions, cast their votes or even submit new ballots if they've changed their mind since they voted.
The district must receive all ballots by the end of the Tuesday meeting.
After the meeting ends, the ballot count will begin, and will be handled by Lake County Registrar of Voters Diane Fridley.
The tabulation of ballots will be announced at a July 15 meeting, also scheduled for 1:30 p.m., to be held at the district's headquarters, 410 Esplanade, Lakeport.
