Lt. Col. James A. DeLapp, U.S. Army Corps of Engineers Nashville District commander, speaks during a ceremony at England Park in Nashville, Tenn., where officials unveiled a high water mark sign. It is the first of more than a dozen high water marks to be placed in different locations around the city. The Corps participated in the "Know Your Line: Be Flood Aware" initiative to draw attention to Nashville's flood risk by showcasing how high the water rose during the historic May 2010 floods. The program was developed by the Federal Emergency Management Agency, National Oceanic and Atmospheric Administration, National Park Service, USACE, U.S. Department of Agriculture, National Resources Conservation Service, U.S. Department of Housing and Development, U.S. Geological Survey, and U.S. Small Business Administration.
