Calling the state of the National Mall in Washington, D.C., an “international embarrassment,” a panel of leading design experts has recommended that the National Park Service amend an improvement plan unveiled earlier this year to make it broader and more environmentally sustainable. The plan calls for a ban on new monuments and statues and a redesign of the Union Square/Capitol Reflecting Pool area. Angela Dye, president of the American Society of Landscape Architects, who facilitated the panel, says the Park Service’s current plan would improve the mall but does not go far enough. The panel recommends the Park Service hold a design competition and work with the National Capital Planning Commission and the Architect of the Capitol to develop a more integrated, expansive and sustainable plan.
