OMAHA, Neb. (AP) – The U.S. Army Corps of Engineers has awarded a $2 million contract for levee repair work along the Missouri River in southwest Iowa and northwest Missouri.  The project includes placing large boulders, known as rip rap, on the river side of new setback levees built near Hamburg, Iowa, and Watson, Mo., following last summer’s historic flooding. The contract also includes installing a filter fabric to help reduce the potential of erosion.  The work should be done by the end of July.  The contract was awarded to Western Contacting Corp. in Sioux City.
