CMS-South Park Campus
Watershed Enhancement
Project Presentation
January 2010
Welcome
 About
Us
 Water Quality issues, current
conditions, and impaired streams
 Stormwater runoff and pollution
issues, causes, and impacts
 What we do to address these issues
 Discuss South Park Campus
Stormwater Project
River Watersheds
Catawba
River
Watershed
Yadkin
River
Watershed
South Park
Campus
Stormwater runoff travels from parking lots, roads, rooftops,
etc. to streams in the Catawba or Yadkin River watersheds
Storm Drainage System
Includes:





Underground
pipes
Open-air
channels
Curb and gutters
Storm drains
Catch basins
Storm Water Pollution
Storm water carries
pollutants to our
streams and lakes.
Pollutants can be things
like:






Oil
Dirt
Animal waste (bacteria)
Fertilizers (nutrients)
Brake dust (metals)
Trash
Stream Use Support Index
Green = Supporting
 Yellow = Partially
Supporting
 Orange = Impaired
 Red = Degraded

Environmental Impacts from
Development and Stormwater Runoff

Eroded Stream Banks

Increased Flooding

Increased Pollution

Decreased Water Quality
& Habitat Conditions

Costly Damage to
Streams, Lakes, Water
Supplies, and Quality of
Life
Environmental Effects of
Stormwater Runoff
These conditions result
from increased runoff and
pollutant discharges to
streams
Environmental Effects of
Stormwater Runoff
Stream Erosion and Silt
Deposition
Storm Water Services
currently has over 6000
calls for service to repair
these conditions
How do we address these
Stormwater Runoff Issues
 Development
Ordinances
 Education
 Watershed
Planning and
Management
 Structural Treatments (BMPs)
Structural Treatments
Bioretention Area
Wetland
Dry Detention Sand Filter
Wet Pond
Structural BMP’s are often incorporated into
the landscape as amenities

Pond retrofit project in a focal area of an
apartment community on Monroe Road
Lush planting stabilizes the shoreline, provides
enhanced pollutant removal, and habitat in ponds

Project History

Why we are here today

How project came about

How we got involved
Project Goals / Benefits
 Treat
stormwater runoff & pollutants
from existing school site
 Provide savings to CMS ~ $60,000 in
required stormwater treatment costs
for proposed school additions
 Improve Water Quality & the
Environment
 Provide Education opportunities for
students
 Amenities for schools
What’s been done to date
 Coordination
w/CMS Facilities
Management
 Feasibility Engineering Study
 Previous meetings with School
Principals and associated groups
 Planning, consider project & site
constraints on Campus
What we plan to do here
 Five
BMP sites proposed on Campus
 Two
Bioretention Areas
 One Dry Detention Sand Filter
 One Grass Swale w/Infiltration
 One Wet Pond
* Wet Pond will provide required stormwater
treatment for proposed building additions at
Myers Park High & A.G. Middle Schools.
Project Next Steps
 Design
 Permitting
 Construction
