Lula estimates it could get $1.9 million from a proposed five-year extension of the special purpose local option sales tax. The amount is based on 2013 census numbers and an overall collection of $155 million, City Manager Dennis Bergin told Lula City Council on Monday night. “We have to identify for the referendum project categories,” he said, adding that he and Mayor Milton Turner have discussed the estimated revenues and how they would be spent.
