Gainesville, Hall County and city Board of Education officials have tabled three requests for taxpayer funding to help renovate Lakeshore Mall, a building along Green Street for Looking Glass Surveys and for completion of phase two of the midtown multiuse trail. Officials on the Tax Allocation District Advisory Committee said they need to identify just how long it would take to recoup this funding, as well as identify parameters and evaluation criteria for approving funding. They hope to revisit the matter in about 30 days with sharper policy guidelines to direct their votes.
