Did you know that the Embassy Row part of Mass Ave is one of the last intact “Grand Avenue” landscapes in the nation? Help us rescue what remains of this landscape and revive the elegant, park-like views of a century ago, with plants appropriate to the 21st century.


We envision Embassy Row in Washington DC as a national landmark, complete with a healthy canopy of major trees and a unifying landscape that revives it.  It will be the best remaining “grand avenue” in the United States and a model for sustainable historic streets everywhere.

“The rhythm and proportions of this broad, tree-lined avenue dynamically interact with the scale and visual excitement of the architecture which abuts it. Creating a street façade unique in the city and perhaps the nation.”
