Alternatives revealed to save sinking Tidal Basin on National Mall
Five landscape architects unveiled proposals Wednesday to save the sinking Tidal Basin on the National Mall in Washington, D.C. The plans run the gamut from a conservative approach to radical reimaginings.
The Tidal Basin connects centuries of American history and includes memorials to Thomas Jefferson, Franklin Delano Roosevelt and Martin Luther King Jr. Some 1.5 million people walk along the basin's rim during the annual Cherry Blossom Festival each spring. But with increased car and foot traffic, the ground underneath is dipping. As sea levels rise, the walkways flood daily.
