Schlitterbahn Waterparks is going to spend “substantially more” than $200 million to develop a huge water park and convention center in Cedar Park, a company spokesperson said Wednesday.

The 95-acre project will be a partnership between Rick Redmond, who co-owns the Volente Beach Waterpark on Lake Travis, Schlitterbahn Waterparks and Cedar Park city hall, Schlitterbahn spokesman Jeffrey Siebert said.

No details on the water park or city incentives have been released, although Schlitterbahn said it will announce plans at a city council meeting Thursday.

The Austin Business Journal reported in 2008 a similar proposed park will also include a convention center that could span up to 100,000 square feet.

It is unknown whether water to fill it will come from Lake Travis or other sources and what impact it will have on water conservation efforts, spokespeople for the Lower Colorado River Authority and Save Our Spring Alliance said.

Cedar Park gets its water from the Brushy Creek Regional Water Authority, which bought rights to Lake Travis water from the LCRA.

Multiple Cedar Park officials could not be reached or declined to comment, and it appears the city instructed employees not to discuss the park until the council meeting.

In 2008, Redmond denied he was working with Schlitterbahn owners on a Cedar Park water park.

“I know them, but right now there’s nothing there,” he said in 2008. “We’ve talked a little bit. … If someday it works out, you never know.”

Phil Brewer, Cedar Park’s economic development director, could not be reached Wednesday. He declined in 2008 to give details about incentives Redmond was seeking from the city, saying a package had not been finalized.

Jill Redmond, owner of Volente Beach Waterpark on Lake Travis and wife of Rick Redmond, said that park will remain open.
