Managing Wet Weather withGreen Infrastructure
a periodic update on activities
Volume 2008, Issue 4 September 2008
In April of 2007, EPA and four national groups signed the Green
Infrastructure Statement of Intent to promote green infrastructure
as a reliable and viable method for managing wet weather. Since
then, 67 national, regional and local organizations haveendorsed a
Stakeholder Statement of Support for Green Infra
structure as a commitment to implement this cost effective and
often environmentally preferable approach to wet weather
management. Engagement and assistance from these partners is
necessary to gain broad-spectrum acceptance for these practices and
remove barriers and regulatory roadblocks. We invite local and
state governments, environmental groups, development groups, and
other entities to join us in our efforts to mainstream the use of
green infrastructure practices. This issue of the Green
Infrastructure periodical focuses on thevarious roles partners can
play: certification & training, outreach, research &
development. If you are interested in be
coming more involved, please call or email one of our contacts.

In early September, EPA Region 5 held a one-day workshop onGreen
Infrastructure for CSO Control for a large audience of localpublic
works officials, government representatives, and environmental
organizations. Speakers from the District of Columbia,New York
City, and Kansas City, Missouri shared informationabout models and
estimations for how to include green infrastructure in CSO areas.
Other topics included benefits, operation& maintenance,
performance standards and design elements, local codes and
ordinances, and incentives to support green infrastructure. For
information on upcoming workshops or interest inhosting a workshop,
please contact Jenny Molloy, USEPA.
Research & Development
Temple University-Ambler Campus established the Center for
Sus
tainable Communitiesin July 2000 to develop and promote
newapproaches to protect and preserve quality of life through
sustainable development. The Center has worked on various
watermanagement projects, including a recent effort to revitalize
theflood-prone Fort Washington Office Park into a Sustainable
OfficePark. The office park site, developed in 1953, was
originallymarshland and is crossed by four creeks. The Center lead
a twoyear study to: evaluate the flooding and transportation
problemsat the office park; recommend solutions to mitigate
flooding, enhance accessibility, and revitalize the office park;
and, preparea Development Implementation Plan with short-term and
long-term recommendations. In addition to removing some of the
buildings, the draft report suggests improving office park
conditions by restoring unnecessary parking lots to a more
naturalstate and by installing green roofs, porous paving, rain
gardens,bioretention swales and basins, and underground cisterns
thatcapture and manage the majority of the stormwater on-site.The
Center also teamed up with the Villanova Urban
StormwaterPartnership to form the Temple-Villanova Sustainable
StormwaterInitiative, which works to advance the practice of
stormwatermanagement through cross-disciplinary research and
outreach.
Three universities, Cornell University, University of California
at
Davis, and Virginia Tech partnered to research the benefits of
using structural soil under pavements. The results of their
experiment found that a 24-inch deep bed ofCU-Structural Soil
withapproximately 30% porosity holds about a 5-inch rain event.
CU-Structural Soil is a patented two-part system comprised of a
rigidstone lattice meeting engineering requirements for a
load-bearing soil, along with a quantity of soil to meet tree
requirements for root growth. The lattice of load-bearing stones
providesstability as well as interconnected voids for root
penetration, air,and water movement.
