Departmental Administration (DA) Operations Staff have been working to implement
multifunctional beneficial landscaping on their grounds. E.O. 13148, Greening the Government through Environmental Leadership,
(recently superseded by E.O. 13423 in 2007) required federal facilities to
incorporate environmentally and economically beneficial landscape practices on
federal grounds into their landscaping, programs, policies, and practices. In the fall of 2006, DA staff kicked off this effort by arranging for the installation of a 1,200 square foot green roof.
Green roofs act like giant bio-filtration sponges
soaking up rain thus helping to retain storm water and reducing excess storm water
runoff which is considered one of the most serious problems facing local waterways and the Chesapeake Bay.
