They agreed to that course of action after looking at both 3- and 5-percent raises.
The 3-percent raise will cost the county about $400,000 a year and will include wages and benefits, said County Auditor Linda Barnette.
Based on preliminary property values, which will be down in 2014, the raise will push the ad valorem tax rate from 27.5 cents to about 29.88 cents per $100 valuation.
That rate is separate from the tax rate of 4.1 cents that is levied to pay for the $15 million Mallet Event Center & Arena.
Last year, commissioners trimmed the overall rate from 35.65 cents to 31.667 cents per $100.
Property values jumped by 19.16 percent for the county last year.
Commissioners also voted in favor of a slight increase in the amount that the county will pay toward retirement benefits for employees.
