County commissioners heard from all three of Covington County’s school superintendents Wednesday before agreeing to move forward with a special election to renew ad valorem taxes for schools.

Specifically voters will consider:

• A 1-mill, county-wide tax that has been on the books for 70 years. This tax must gain 60 percent approval by voters on election day.

• A 3-mill, county-wide tax that has been on the books since 1985.

• A 3-mill, district tax, that also has been on the books since 1985. Andalusia voters must approve this for the tax to continue in Andalusia; Opp voters must approve for the Opp district; and all other voters must approve for the county.

One mill of property tax equals 10 cents on each $100 of property value, or $1 in taxes for every $1,000 of assessed value.

The special election has been set for Tues., March 10, 2015.
