Commissioners voted unanimously Tuesday to refer the proposal back to the authority for specifics on how much it will cost to run the program and how much revenue it expects.
Commissioner Don Grantham asked DDA Executive Director Margaret Woodard to come up with a business plan for commissioners to consider.
"We've had costs presented without any revenue stream," he said. "I'm asking the DDA not to be dependent on the general fund."
City Administrator Fred Russell suggested that the DDA schedule a session with commissioners to allow them to ask questions and express concerns they have received from the public about the parking proposal.
DDA member Sanford Loyd took exception to the motion and said the ordinance had been to commission committees twice and to the full commission twice.
"The process had gone on for quite some time," he said. "I guess I just don't understand the process, the process in terms of where we are."
Russell said the proposal would not be complete - and commissioners not satisfied - until the concepts, methodology and verbiage were understood.
"This time we're talking specifics," he said. "This time we're talking words."
Loyd said the verbiage has been in place all the time and had not changed.
Commissioner Bill Lockett challenged that statement, saying the numbers had changed from meeting to meeting.
"People aren't stupid," he said. "You write a ticket, put a boot on a car, they aren't coming back. If you were using your own money, you wouldn't be for it."
Mayor Pro Tem Alvin Mason said the DDA could agree to meet with commissioners and give them the specifics or they could vote right then, and he didn't think all commissioners were on board.
