Bay foundation gives cash to help build Nationals Green Roof

The
Washington Nationals’ new ballpark will contain what its architect, HOK Sport,
says is the first “green roof” at a big league sports facility when
it opens in April.

The Chesapeake
Bay Foundation, an environmental nonprofit in Annapolis, gave a $101,670 grant
to the D.C. Sports and Entertainment Commission to cover the cost to plant
grass and other plant life on top of a 6,300-square-foot waterproof surface
above a concession stand.
