Not all are agreeing with the new plan.
Hilton Head Island and Bluffton already collect traffic fees from developers that bring new businesses to the area, and the fees help pay for new roads, traffic signals and road improvements. But municipalities like Beaufort and Port Royal won't charge the fees because they say it scares off developers.
Now, the Beaufort County Council wants to pass an ordinance making it mandatory for all municipalities to participate.
"The developer will actually be responsible for paying whatever it takes to ensure that the traffic from that new development doesn't undo the traffic plan," said council chairman Tom Taylor.
Under the ordinance, commercial developers will be required to present the county with a traffic impact analysis, then pay for the necessary changes.
The county plans to go forward with the ordinance next month, even if it doesn't have support from the northern municipalities.
