Work to begin on Washington levee

A new barrier is to be constructed to protect downtown Washington DC and the National Mall from floods in the event of a storm, US Army officials have said.

Work will begin in late November or early December on a £6M levee to prevent damage in the event of flooding from the Potomac River.

Washington’s flood-control system, built around 70 years ago, is inadequate for a major storm, the US Army Corps of Engineers concluded after Hurricane Katrina.

The Corps has estimated that a major storm could cause £125.2M worth of damage to museums, memorials and federal office buildings.

The new project, to be completed next summer, will add stone walls to both sides of 17th Street. A removable section of posts and metal panels will also be installed alongside the earth barrier that parallels the reflecting pool at the Lincoln Memorial.
