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

Many of our

recommendationsincorporate what worked

from other sustainability

ranking systems

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
