North Oconee River Watersheds Tanyard to Lilly Branch

Outline of Presentation Overview of Project Current Watershed Conditions Potential Sources of Pollution & Controls Invasive Species Education and Outreach Public Input

Project Goals The goal is to improve water quality and watershed ecosystem health while affording opportunities for passive and active education and engaging the campus and ACC Community.

9-Elements Identification of pollutant sources Estimate of expected improvements from recommendations Description of management measures & critical areas Estimate of amounts of technical & financial assistance Information and education component Schedule for implementation Description of interim milestones Set of criteria for determining success Monitoring component to evaluate progress

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

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

Watershed-wide analysis of BMP opportunities: S TORMWATER What is stormwater runoff? Problems associated with stormwater – Water Pollution – Flash Flooding – Erosion

Watershed-wide analysis of BMP opportunities: M ANAGING S TORMWATER - BMP S Best Management Practices (BMPs) Structures that either: Slow stormwater down so it can soak into the ground Or: Collect stormwater for future reuse Examples

Watershed-wide analysis of BMP opportunities: A NALYSIS 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

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!

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

Invasive Species - Lilly Branch Site Owner: UGA Approximate Area: 0.80 acres Primary species of concern: Chinese Privet

Tanyard #1- Cemetery Owner: UGA Approximate Area: 0.91 acres Primary species of concern: Chinese Privet, Periwinkle

Tanyard #2- Tate Center Owner: UGA Approximate Area: 0.52 acres Primary species of concern: Chinese Privet, Periwinkle, Bush Honeysuckle, Oregon Grape

Tanyard #3- Pope Street Owner: Athens-Clarke County Approximate Area: 0.10 acres Primary species of concern: Chinese Privet, Kudzu, Japanese Honeysuckle, Carolina Geranium

Education Program… Objective: To create a long-term outreach program at Barrow Elementary School that educates students about stormwater

Education Program… Curriculum included: – Watershed modeling activity – Role playing – Field trip to Tanyard Creek – Brainstorming solutions – Distributed materials – Multimedia

Education Program… Outcome: -over 100 students in four 3 rd grade classes -2-part curriculum met several GPS -ties into conservation unit -requires few materials  replicable for future
