Green Roofs - Living Architecture Monitor - Spring 2018 - 28

POLICY

WASHINGTON DC DEVELOPS
MULTIPLE INITIATIVES IN SUPPORT
OF LIVING ARCHITECTURE
BY EMMA TAMLIN, ASSOCIATE EDITOR, LIVING ARCHITECTURE MONITOR

According to the Department of Energy and Environment (DOEE),
as of 2017, there are currently more than 3 million square feet of green
roofs in the District. The rise in green roofs in DC can be attributed to
the city's rigorous stormwater regulations and grant programs designed
to provide incentives for the installation of green roofs.

D

C receives more than 40
inches of rainfall each year
and with more than 43 per
cent of the Districts land
cover being impervious, a single
1.2-inch storm falling on the
area can produce as much as 525
million gallons of stormwater
runoff.
Over the years, the DOEE
has been very successful in its
green infrastructure policy
creation and implementation.
Stricter stormwater regulations were introduced, along
with the Green Area Ratio,
RiverSmart programs, and the
Stormwater Retention Credit
Trading Program.
In 2013, the DOEE released

the 2013 Rule on Stormwater
Management, Soil Erosion,
and Sediment Control (2013
SWM Rule). The DOEE
recognized soil erosion due to
stormwater runoff as a key factor in decreased water quality
in the District's streams and
rivers. In addition, the Office of
Planning navigated the passing
of the Green Area Ratio (GAR)
through the Zoning Commission. According to the DOEE
website, the GAR is an environmental sustainability zoning
regulation that sets standards
for landscape and site design to
help reduce stormwater runoff,
improve air quality, and keep
the city cooler.

The DOEE also promotes
stormwater management
through its various RiverSmart
Programs. RiverSmart Programs provide financial incentives to help property owners
install green infrastructures
such as rain barrels, green
roof, rain gardens, permeable
pavers, shade trees, and more.
The rebate program, since
its inception in 2006, offers a
rebate of $10 - $15 per square
foot for voluntary installations
of green roofs and has greatly
contributed to the installation
of green roofs District-wide.
The array of policies and
programs available in DC
increases compliance as de-

velopers and property owners
are able to choose the option
that best meets the specifications of their project. DC is a
leader in green infrastructure
policy and has implemented
a diverse set of solutions to
mitigate stormwater runoff
while simultaneously promoting the installation of green
roofs, improving human health
and establishing a market for
stormwater retention.
One of the most interesting
programs and potentially the
most transformative is the
new stormwater credit trading
which is profiled on the next
page.
