A live-entertainment venue on Lake Pontchartrain that would include an open-air market got the green light Thursday from the New Orleans City Council.

The 5,000-person theater, combined with restaurants and retail space, would be built at the site of the former Bally’s Casino dock, which has been vacant since Hurricane Katrina.

The project, expected to cost about $13 million, was proposed by Roland Von Kurnatowski, the owner of Tipitina’s and the Orpheum Theater.

The council signed off on the project by a 6-0 vote, with Councilwoman Stacy Head absent. The City Planning Commission gave its unanimous approval to the project in late May.

The project is planned for a 19-acre site next to Lakefront Airport and includes plans for a fuel dock and marina supply store as well as a boathouse that would be leased to the National World War II Museum to house a restored Navy torpedo boat.

“We think it’s an excellent opportunity to put family and entertainment for young people and cultural development with food and music right there on the lake in a setting that will make it extremely enjoyable for all citizens to attend,” Von Kurnatowski said.

The property is owned by the Orleans Levee District and managed by the state Non-Flood Asset Authority, which has signed a 50-year lease with Von Kurnatowski’s company.
