Explanation
1. BACKGROUND: This project is being completed as part of the City’s Blueprint Columbus program. This project will construct various types of green infrastructure (GI) throughout the neighborhood which will provide a higher water quality within the region by treating the surface runoff before it discharges to the waterways.
