PROJECT MISSION:

To reduce stormwater runoff from residential and commercial rooftops.


TARGET AUDIENCE:

Homeowners and owners
of commercial properties in the District of Columbia and surrounding areas.


MESSAGING:

Green roofs reduce stormwater runoff.



rainwater is stored by the media, absorbed by the plants, then returned to the atmosphere; in
summer 70
-
90%, is retained; in wint
er between 25
-
40%



green roofs also moderate the temperature of the water that happens to run off, improving water
quality for marine life



green roofs delay the time that runoff occurs, reducing the number and volume of overflows in
combined sewer systems (
CSOs)



green roofs slow the velocity of direct runoff, reducing erosion of stream and river banks, and the
sedimentation and loss of habitat that result
