Shive-Hattery Inc., which has offices in Moline, and its vice president, Myron Scheibe, are being sued for breach of contract by River Eagle Investments LLC, which owns 132 acres along the Mississippi River, including the former vacant Case New Holland plant in East Moline.

The lawsuit, filed Monday in Rock Island County Circuit Court, states that Scheibe, as point person on the River Eagle project, was simultaneously involved with development of a competing project 2 miles away in Moline.

Scheibe is secretary and member of the executive committee of Renew Moline. The lawsuit claims that Renew Moline is overseeing development of the RiverTech site, 15.5 acres on River Drive between 25th and 29th streets, owned by the city of Moline.

“That is absolutely false,” Scheibe said Wednesday, denying any involvement in RiverTech.

He said Renew Moline is a nonprofit economic development organization that offers assistance to the city of Moline.

“We do intend to aggressively defend ourselves in this case,” Scheibe said.

The lawsuit states Scheibe has “caused Shive to repeatedly breach its agreements” with River Eagle and claims the defendants are trying to extort money from the plaintiff by refusing to hand over architecture plans for the River Eagle project unless they’re paid.

“We agreed to provide electronic copies of all of our work product, which we indeed did,” Scheibe said.

The River Eagle project was announced in 2010. In November 2011, River Eagle unveiled plans for construction of an 18,000-square-foot strip center, a convenience store, a financial institution and other retail space along East Moline’s 12th Avenue. Future phases of the proposed project include more strip centers, a boardwalk along the river and restaurants and more retail on the boardwalk.

James Oakley, a Chicago-based attorney representing River Eagle, said the defendants’ actions as outlined in the complaint have caused the East Moline project to be delayed.
