Flowery Branch is moving toward a fiscal 2013-14 budget with the tax rate remaining the same, but with local option sales taxes remaining an unknown factor because of an ongoing dispute between Hall County and the cities. City officials projected an additional $250,000 in LOST revenue, or an increase from $347,000 to $597,000 next fiscal year, which begins July 1. That was done “not knowing for sure exactly how much (the amount) will be or when it will come in,” Finance Director Jeremy Perry told Flowery Branch City Council on Thursday night.
