The city of Davenport gaming consultant said an interstate casino will bring in big bucks but some city officials may want the casino to stay downtown.
The city hoped that a casino off the river would have the same success as Jumer's in Rock Island by increasing the Quad Cities' gaming market by 10 percent.
But the gaming consultant believes an interstate casino could expand and create more gaming revenue.
Since the developer wants to split the license, there is still an opportunity for gamblers to play downtown.
"I think a highway location offers a much better opportunity at growth," Davenport Gaming Consultant Gary Buettner said. "So, to increase the market the most effective way I would suggest contemplation of those facts."
Building on the interstate could cost $46 million to purchase Rhythm City plus 5 million more.
The Restoration St. Louis proposal would like to build downtown but the only way it could expand is up.
City council will meet next Wednesday to negotiate with both developers.
The R.D.A. has to approve the developer and the Iowa Racing and Gaming Commission gets the final say.
