The U.S. Army Corps of Engineers has approved the City of Rock Island's plans for flood protection during the Armory Park construction project. This permits Williams Construction Management/Valley Construction, the city's construction manager, and its subcontractors to proceed with starting the permanent flood-protection system north of the existing Armory building and then demolishing the Armory. The first step in the process is to install steel sheet piles on the north side of the Armory, followed by demolition of the Armory building. No date has been set for the demolition. The project is expected to be completed in 2010.
