New Landscape Rating System to Transform the Industry, Complete Green Building Puzzle

National Sustainable Landscape Program Calls for Pilot Projects
WASHINGTON--(Business Wire)--
Today, the Sustainable Sites Initiative released the nation`s first rating
system for the design, construction and maintenance of sustainable landscapes,
with or without buildings. A partnership of the American Society of Landscape
Architects (ASLA), the Lady Bird Johnson Wildflower Center and the U.S. Botanic
Garden, the Initiative`s rating system represents four years of work by dozens
of the country`s leading sustainability experts, scientists and design
professionals, as well as public input from hundreds of individuals and dozens
of organizations to create this essential missing link in green design. The
announcement took place at the U.S. Botanic Garden in Washington.

"While carbon-neutral performance remains the holy grail for green buildings,
sustainablelandscapes move beyond a do-no-harm approach," said Nancy Somerville,
Executive Vice President and CEO of ASLA. "Landscapes sequester carbon, clean
the air and water, increase energy efficiency, restore habitats and ultimately
give back through significant economic, social and environmental benefits never
fully measured until now."

"We are facing unprecedented environmental challenges such as water scarcity and
climate change that require fundamental changes in the way that we interact with
the land," said Susan Rieff, Executive Director of the Lady Bird Johnson
Wildflower Center at The University of Texas at Austin. "This voluntary rating
system and guidelines covers all aspects of working with outdoor spaces of all
sizes, and provides information for designing landscapes that go beyond beauty
to actually improving ecosystem health and the health of communities for
generations to come."

"Landscapes can give back," said Holly H. Shimizu, Executive Director of the
United States Botanic Garden. "We believe that as these guidelines become widely
used, not only will they be as transformative to the landscape industry as LEED
was to buildings, but more than that, they will allow built landscapes to be
regenerative like natural landscapes, and assist in mitigating some of the most
pressing environmental issues we face today. We need to acknowledge our
landscapes` value, treasure them and cultivate them sustainably and responsibly.
The need is urgent, the time is now and these guidelines, when used correctly,
are the tools."

The rating system works on a 250-point scale, with levels of achievement for
obtaining 40, 50, 60 or 80 percent of available points, recognized with one
through four stars, respectively. If prerequisites are met, points are awarded
through the 51 credits covering areas such as the use of greenfields,
brownfields or greyfields; materials; soils and vegetation; construction and
maintenance. These credits can apply to projects ranging from corporate
campuses, transportation corridors, public parks and single-family residences.
The rating system is part of two new reports issued from the Initiative, The
Case for Sustainable Landscapes and Guidelines and Performance Benchmarks 2009,
both available for download at www.sustainablesites.org.

To test the rating system, the Sustainable Sites Initiative opened a call for
pilot projects in conjunction with the release of the rating system. Any type of
designed landscape is eligible, so long as the project size is at least 2,000
square feet. The call will remain open until February 15, 2010, and the
initiative will work with and oversee the projects during the two-year process.

About the Lady Bird Johnson Wildflower Center

The Lady Bird Johnson Wildflower Center at The University of Texas at Austin is
dedicated to increasing the sustainable use and conservation of native plants
and landscapes. Founded in 1982 by Lady Bird Johnson, the former first lady, the
Wildflower Center maintains an extensive native plant botanic garden and offers
professional and adult education. The Wildflower Center also conducts research
on landscape restoration and plant conservation at its 279-acre site, promoting
the role of native plants in addressing ecological problems. Recent research
initiatives focus on native turf grasses, green roof technology in a
sub-tropical climate, prairie restoration methods including prescribed fire, the
control of invasive species, and ways in which native plants can aid in
combating climate change in urban landscapes. Learn more at www.wildflower.org.

About the United States Botanic Garden
