Officials say though probability is low, if the District of Columbia Levee System is overtopped with flood water and breaks, it could result in loss of life, billions of dollars in damages and major disruption to the national government. The U.S. Army Corps of Engineers and National Park Service are hosting a public meeting Oct. 30 at 6:30 p.m. at the Westminster Presbyterian Church (400 I Street SW) to share information on flood risks, preparedness measures and evacuation procedures to people who live, work or spend any time behind the levee system near the National Mall.
