Waco Plan Commission Director Bill Falco explained how the ordinance would work.
"In order to put up a new billboard, a normal billboard, you would have to take down two to put up one," he said.
And if it's a digital billboard, four will have to come down for one to go up.
Currently, new billboards are temporarily forbidden.
The "cap and replace" policy is modeled after an ordinance in San Antonio where they have experienced a 20-30 percent drop in billboards over the last couple of decades.
