The field of Rooftop Gardens is relatively new, and most of the activity
has involved larger buildings. But green roofs are increasingly an
available option. They can be as fun and rewarding as they are useful.
Your efforts can range from full roofing systems to trays of plants
placed to catch the rain.

Some other Stormwater Management suggestions:
• Disconnect
your downspout to direct water onto the ground, rather than overload
your local sewer.
• If
your roof can’t support a full garden, consider potted plants
or any other variation on the theme. By catching the rain and releasing
it through evaporation, you still help solve problems.
• Permeable
pavements for patios, driveways and decks can allow water to seep
into the ground, rather than flooding sewers and arriving—unwanted—in
your basement.

Roofs for Healthy Cities
A green roof system is an extension of the existing roof, which involves
a special waterproof and root repellant membrane, a drainage system,
filter cloth, a lightweight growing medium and plants. Green roof
systems may be modular, with drainage layers, filter cloth, growing
media and plants already prepared in movable, interlocking grids,
or, each component of the system may be installed separately.

of Environmental Services and the Office of Sustainable Development.
The program promotes ecoroofs by researching ecoroof technologies
and providing information and technical assistance to community members.
