Flowery Branch city officials are proposing an increased 2015 budget, reflecting the first tax increase in nine years. The proposed general fund budget jumps around 17 percent, from the approved $2.9 million for fiscal year 2014 to $3.4 million. Some of that increase is reflected in a higher millage rate, from 2.837 mills — where it’s been for the past nine years — to 3.337.
