Hall County plans to present to the cities by Oct. 15 an intergovernmental agreement concerning a new five-year round of special purpose local option sales tax money, Lula City Manager Dennis Bergin said Monday night. The agreement could be presented “hopefully within the next couple of weeks,” Bergin told the council. And then the county would establish “tier two” projects at an estimated amount of $21 million, or a layer of projects with countywide benefit.
