Watershed Issues• Heavy urbanization in the watershed (lots of
pavement)• Piped for large portions of reach• Polluted• Invasive species• Not always seen as amenities (places to throw
trash, etc.)• Recent work by the UGA Grounds department to
identify sources of contamination and by university architect to filter run-off

Lilly Branch• Poor Water Quality
– Hydrocarbon Pollution (Leaking underground storage tanks)– Fecal Contamination– High Conductivity and low Ph
• High Storm Flows (leading to erosion and undercut banks)
• Limited Riparian Corridors• Invasive Species• Native Diversity (salamanders)• Daylight section by Lamar Dodd School of Art with
stormwater BMP’s• Community and Campus Amenity

Tanyard Branch• 2.02-square kilometer watershed • 74% impervious surface• Approximately 50% of the stream length is piped• Impaired: failure to meet designated use of fishing as a result
of fecal coliform levels (also high conductivity and low Ph)• High storm flows lead to eroding and undercut stream banks• Invasive species• Recent Watershed Characterization by ACC Stormwater• Grounds department water quality monitoring and clean-up• Highly visible near the football stadium with daylighted
sections in the community

Clean Water Act
• The discharge of any pollutant from a point source into navigable waters is unlawful unless made according to terms of a NPDES permit
• Requires local governments to add discharge ordinances
• Enforcement Provisions– Government Enforcement– Citizen Suit Provision
![Page 15: Watershed Protection Plan North Oconee River Watershed Tanyard to Lily Branch Upper Oconee Watershed Network University of Georgia Grounds Department Environmental](https://reader035.vdocument.in/reader035/viewer/2022081519/56649d085503460f949d9941/html5/thumbnails/15.jpg)
ACC Illicit Discharge and Illegal Connection Ordinance
• It is a violation for any person to throw, drain, or otherwise discharge…into the ACC separate storm sewer system any pollutants or water containing any pollutants, other than storm water
• Notification Requirement• Enforcement/Penalties
![Page 16: Watershed Protection Plan North Oconee River Watershed Tanyard to Lily Branch Upper Oconee Watershed Network University of Georgia Grounds Department Environmental](https://reader035.vdocument.in/reader035/viewer/2022081519/56649d085503460f949d9941/html5/thumbnails/16.jpg)
Watershed-wide analysis of BMP opportunities:
STORMWATER
• What is stormwater runoff?
• Problems associated with stormwater– Water Pollution– Flash Flooding– Erosion
![Page 17: Watershed Protection Plan North Oconee River Watershed Tanyard to Lily Branch Upper Oconee Watershed Network University of Georgia Grounds Department Environmental](https://reader035.vdocument.in/reader035/viewer/2022081519/56649d085503460f949d9941/html5/thumbnails/17.jpg)
Watershed-wide analysis of BMP opportunities:
MANAGING STORMWATER - BMPS• Best Management
Practices (BMPs) Structures that either:
• Slow stormwater down so it can soak into the ground
Or:• Collect stormwater for
future reuse
Examples
![Page 18: Watershed Protection Plan North Oconee River Watershed Tanyard to Lily Branch Upper Oconee Watershed Network University of Georgia Grounds Department Environmental](https://reader035.vdocument.in/reader035/viewer/2022081519/56649d085503460f949d9941/html5/thumbnails/18.jpg)
Watershed-wide analysis of BMP opportunities:
ANALYSIS• Suggest BMP opportunities
throughout the system, considering site conditions, location in the watershed, and need
• Consider how BMPs can work together
• Find tools to help prioritize BMP implementation
![Page 19: Watershed Protection Plan North Oconee River Watershed Tanyard to Lily Branch Upper Oconee Watershed Network University of Georgia Grounds Department Environmental](https://reader035.vdocument.in/reader035/viewer/2022081519/56649d085503460f949d9941/html5/thumbnails/19.jpg)
Invasive Species - Background
• Part of a larger effort to restore severely impaired urban streams
• Overwhelming presence of invasive exotic flora– Outcompete native flora– Depending on species, can lead to severe bank
erosion• An opportunity to educate!
![Page 20: Watershed Protection Plan North Oconee River Watershed Tanyard to Lily Branch Upper Oconee Watershed Network University of Georgia Grounds Department Environmental](https://reader035.vdocument.in/reader035/viewer/2022081519/56649d085503460f949d9941/html5/thumbnails/20.jpg)
Invasive Species - Site Selection
• We selected sites for invasives control based on 3 criteria:1. Property ownership- only properties owned by
the University of Georgia or Athens-Clarke County
2. Public visibility- only sites easily visible to the public
3. Probability of successful control/eradication- relatively small sites, increasing intensity of management and likelihood of success
