The Hall County Board of Commissioners voted 4-1 Thursday night to approve a $90.268 million budget for the 2015 fiscal year that includes a full rollback of the property tax rate. Commissioner Craig Lutz cast the lone dissent on the budget, though he did vote to set the tax rate at 5.989 mills. A mill represents $1 for each $1,000 of property value, which is assessed at 40 percent in the county.
