The Gwinnett County Board of Commissioners voted 3-1 Tuesday to authorize negotiations with a developer who wants to build a hotel at the county’s convention center.

Nilhan Hospitality wants to build a 300-room Marriott hotel at Gwinnett Center at no cost to taxpayers. A majority of commissioners believe Gwinnett has nothing to lose.

“It’s appropriate to proceed with trying to flesh out the details,” said Chairwoman Charlotte Nash.

Commissioner Mike Beaudreau voted against the proposal, citing concerns about Commissioner John Heard’s business ties to the developer. Heard abstained from voting.

Commissioners must still approve a final agreement.
