… Yet since Congress declared the National Mall a “substantially completed work of civic art” in 2003, it has endured piecemeal growth and environmental effects that threaten the vitality and sustainability of this national treasure. The National Mall Coalition (formerly National Coalition to Save Our Mall) is dedicated to creating a new comprehensive visionary plan for the Mall that advances the legacy of the two historic visions – the 1791 (1st Century) L’Enfant Plan and the 1902 (2nd Century) McMillan Plan. A vision for the 3rd Century Mall will ensure coherent evolution and growth that serves the public’s interest and continues to tell our country’s unfolding story.
