Aldermen on the Council’s Budget Committee are scheduled to reconvene at 8:45 this morning to consider a contentious list of initiatives the mayor plans to fund with nearly $15 million in leftover property tax rebate dollars. Budget Chair Carrie Austin (34) held the item yesterday, telling reporters after the meeting that she wasn’t completely sold on the list of incentives, especially a $500,000 appropriation to plant a thousand trees across the city.
