Wichita ? The Sedgwick County Commission’s decision to put off a referendum on building a casino may have ended plans for a resort casino in Park City, former Wichita Mayor Bob Knight said.

The commission agreed at a meeting Wednesday to indefinitely defer voting on the referendum.

“The governor and the state tell us we have to get local approval and this was the way,” said Knight, who is helping Park City lobby for the casino. “Now we can’t get that. Most of our options are pretty much foreclosed on.”

In January, Knight and other supporters unveiled plans for a $200 million resort casino, with a 300-room hotel, three restaurants, an event center and an indoor-outdoor water park. The proposal is for construction in conjunction with the Iowa Tribe of Kansas and Nebraska under the American Indian Gaming Act.

Two developers also have competing plans to build a hotel and casino in downtown Wichita.

In August, the five commissioners had supported a nonbinding referendum on the issue. But some of them changed their minds Wednesday, after Rep. Brenda Landwehr, R-Wichita, and eight other legislators told them that the casino issue should be decided by the state, not the county.

They also brought a document to the meeting showing that 20 of the 29 state legislators from Sedgwick County opposed the referendum.

County Commission Chairman Dave Unruh said he didn’t want to approve a referendum that so many local legislators opposed.

“No matter what we do, this falls back to the state Legislature,” Unruh said.

Only one commissioner said that she was prepared to vote for a referendum.

Lucy Burtnett, who represents Park City, said “people still deserve a vote on this issue.”

Other commissioners said phone calls, letters and e-mails from those opposed to the casino far outweighed supporters.
