Green Infrastructure Effectiveness

Scientifically Proven Treatment

From 2016 to 2023, Ohio State performed water quality monitoring for Blueprint Columbus within the Clintonville 1 project area to determine the effectiveness of Blueprint’s core goal to decrease total suspended solids (TSS) loads by 20 percent from stormwater before it enters our rivers.

From 2017 to 2021, Columbus implemented infrastructure improvements in a rolling fashion: green infrastructure, sanitary sewer lateral lining/downspout redirections and sump pump installations, occurring over approximately three years.
Ohio State completed the report in 2024.

Full Effectiveness Study

To evaluate the holistic impacts of the Blueprint Columbus Project, stormwater runoff was monitored from July 2016 to October 2023 from three treatment sewersheds (Blenheim, Indian Springs, and Cooke-Glenmont) and a control sewershed (Beechwold) in the Clintonville neighborhood of Columbus.
