Abstract
Restoring two streams, two lakes, and protecting
a buffer are part of a plan to improve the health of
South Fork Peachtree Creek based on environmental, social
and financial criteria. DeKalb County is similar to
many metro-Atlanta Georgia communities with a Storm
Water Management Plan and a Watershed Protection Plan
to fulfill state and federal regulations. In developing Watershed
Management Plans to satisfy these requirements,
DeKalb County chose to use the triple bottom line (TBL)
approach to prioritize different Watershed Improvement
Plans. The prioritization method allows flexibility and
consistency while evaluating environmental, social and
economic measures and identifying projects with the
greatest value per dollar.
We wanted a TBL model that used science based
methods and was easy to implement to determine if a project
would benefit the health of the stream. A TBL model
that can evaluate the best environmental project must be
able to recognize that there are different types of assets
and include projects such as detention pond retrofits and
stream restoration projects. The Prioritization Matrix developed
here uses a grid analysis to weigh different TBL
measures in order to select the best overall environmental
project.
