The U.S. Army Corps of Engineers' commander general says the nation is falling behind on maintaining its aging levees, dams, ports and harbors.

Lieutenant General Thomas Bostick spoke on Thursday during the Society of American Military Engineers conference in Kansas City, Missouri.

He says finishing all the projects that have been authorized would cost about $23.5 billion dollars, but the corps' annual budget for the work usually hovers around $1.5 billion. And that doesn't include addressing their maintenance backlog.

Kansas Gets C- For Infrastructure

May 22, 2013

Civil engineers have given Kansas' infrastructure an overall C-minus grade.

The regional chapters of the American Society of Civil Engineers released their report card Wednesday.

It's an evaluation of the state's aviation, bridges, roads, dams, drinking water, energy, levees, railroads and schools.

The engineers found the most faults with the state's bridges and dams, rating them a D-minus. They say Kansas has nearly 3,000 structurally deficient bridges.

They awarded the highest grades for the state's roads and schools; both got a C-plus.
