Bioretention Efficacy on Interstate 20 in Atlanta for Water Quality Assessment

Learn about a research presentation examining the effectiveness of bioretention cells installed along Interstate 20 in Atlanta for managing stormwater runoff and improving water quality. Explore how developed urban areas and climate change contribute to flooding issues, particularly affecting the neighborhoods of Peoplestown, Summerhill, Mechanicsville, and Pittsburgh in South downtown Atlanta. Discover Georgia Department of Transportation's first green infrastructure project, completed in 2020, featuring two bioretention cells at the crossroads of I-75/I-85 and I-20. Examine the research methodology involving automated samplers to collect stormwater samples, analysis of 20 different parameters including phosphorus and nitrogen, and laboratory-scale modeling to study short-circuiting potential. Understand how these bioretention systems aim to address recurring floods, water quality concerns, and environmental justice issues in Atlanta's affected communities.
