Sustainable Design: PEACH Roads

The Preserving Environment And Community Heritage (PEACH) Roads program started in 2010 as a self-certification program that distinguishes transportation projects and operations based on the extent to which they incorporate sustainable choices.

This is primarily an internal management program for Cobb DOT to measure our performance, recognize good practices, and identify where we need to improve. It also provides Cobb County with a way to demonstrate to the public how we are advancing sustainable practices.

Cobb DOT project designs and operations are evaluated for sustainable practices, and based on the total credits received, an appropriate certification level is assigned. The rating system recognizes varying certification levels, with the highest level going to designs and operational groups that clearly advance the state of sustainable transportation solutions.
