YES!
PEACH Roads functions as
expected
It contains all the
sustainability metrics
expected
Ample proof from NewYork GreenLITES Program
Can PEACH Roads be
improved? YES!
PEACH Roads is not a
perfect system

CCDOT Developed the PEACH Roads Certification program to:
1. Recognize and increase awareness of the sustainable methods andpractices they already incorporate into their project designs.
2. Expand the use of these and other innovative alternatives which willcontribute to improving transportation sustainability
PEACH Roads Design Certification Manual
Most of our recommendations are ways for CCDOT to achieve these two
goals

A 2% increase to upfront construction costs from sustainable building methods
typically yields a life-cycle savings of ten times the initial amount invested.
-Californias Sustainable Building Task Force, 2003
Benefits
Reduced O&M costs
Lower emission costs
Reduced water & energy use
Improved air quality
Better public health
Improved public image
Costs
Can be more expensive
More time consuming in
design phase
But when you incorporate
sustainable practices into design,
the costs will go down.

Cobb County, Georgia:
Cobb County DOT Unveils New
Transportation Sustainability
Ratings Program
Cobb County recently
undertook an initiative to
help identify and scale the
degree of sustainability for
new Department of
Transportation (DOT)
construction projects.
While the Cobb County
Department of
Transportation (CCDOT)has always incorporated
sustainable design into
their overall
transportation plan, they
realized that recognizing
the most sustainable
projects would positively
reflect upon their overall
goal of cost-efficient,
sustainable engineering.
The biggest obstacle
to this initiative was designing a comprehensive,
universal scoring system that could recognize
and properly weight sustainable engineering
practices for a wide rangeof project sizes. After
considerable planning, the
CCDOT adopted the
Preserving Environment
and Community Heritage
(PEACH) Roads scorecard
rating system. The idea of
scoring sustainability is
not a new concept. The
building construction
industry has used the
Leadership in Energy and
Environmental Design(LEEDTM) to rate buildings
since 1998. Because no
national roadway
sustainability system
currently exists, CCDOT
adopted PEACH Roads to
serve a similar purpose.
The PEACH Roads
scorecard was primarily
based(continued on pg.

Be concise; specific examples
minimize confusion
minimize subjectivity FHWA, LEED examples
FHWA: One to three (1-3)
points are given if the project
treats*s+ eighty percent (80%)
or more of the managed runoff
for sediments for an area
greater than the target
impervious surface area.
1 point: 80% is treated
2 points: 90% is treated 3 points: 100% is treated
Possible PEACH Roads Example: S-1c. Alignments which minimize overall
construction footprint.
1 point: 10% reduction in construction footprint
2 points: 20% reduction in construction footprint16
