2. BACKGROUNDBACKGROUND

3. Urban Communities
• United States metropolitan areas, such as Atlanta, GA,
have experienced enormous population and economic
growth within the last century.
• The rapid expansion in the oldest part of U.S. urban
areas led to placing these surface water channels in a
network of underground pipes, known as the combined
sewer systems, that was designed to keep the streets dry
by collecting the water runoff as well as the domestic
sewage.

4. Proctor Creek
• Proctor Creek is a waterway that originates in downtown
Atlanta
• It flows through communities such as English Avenue, Vine
City, Atlanta University Center, Mozley Park, West
Highlands, Grove Park, Center Hill Park, Carey Park and
Bankhead neighborhoods, and many others.

5. Proctor Creek
• The communities surrounding Proctor Creek
suffer from public health threats related to
flooding and disease causing organisms such
as viruses, bacteria, and protozoa, released
during sewer overflow discharges, especially
the communities at lower elevations.

14. Conceptual PlanConceptual Plan

15. Objective
To develop a conceptual plan reducing storm water
runoff from the Atlanta University Center
(Catchment 1) by utilizing green infrastructure to
capture 7.2 million gallons of storm water.

16. Overall Study Area
The Atlanta University Center
is at higher elevation than
most of the communities in
the Proctor Creek Watershed.
By implementing Green
Infrastructure throughout the
AUC, there is the potential to
mitigate the amount of
stormwater runoff that impacts
nearby lower elevation
neighborhoods.

17. Our Study Area
• Our conceptual plan focused on a particular catchment
area entitled Catchment #1. It mainly encompasses:
- Clark Atlanta University (CAU)
- A few small areas of Morehouse College
- Parts of the community surrounding the Atlanta
University Center (AUC)

18. Methods/Fieldwork
1. Collected aerial maps of of Catchment #1
2. Interviewed facility management
3. Participated in meetings and fieldwork

19. Methods/Fieldwork
4. Calculated surface area of buildings and open space to
determine storm water runoff
5. Identified cistern locations
6. Selected green infrastructure to accomplish our objective of
detaining 7.2 million gallons of storm water runoff.
