The Aiken County Council voted 6 to 4 in favor of supporting the financing of Project Jackson at a public hearing Tuesday night.
The council's third and final vote on Project Jackson will be at their meeting next week.
Hundreds of people carrying signs for and against the development crowded into an auditorium at Aiken Tech for the hearing.
The council has been asked to help fund the North Augusta development by participating in a Tax Increment Financing district for 30 years.
The $150 million proposal includes plans to build a minor league baseball stadium and luxury hotel.
During the hearing several private investors said if Project Jackson is approved, they'd move to the riverfront and pour tens of millions of dollars into the county.
"I have a property in Augusta and I'm looking to relocate to Hammond's Ferry and move my tax dollars here to North Augusta; so we're very excited about this project," said Kimberly Hard who is the CEO for Be Well Consultants.
