Blueprint Plan Cover

Blueprint Columbus was approved by the Ohio EPA on December 1, 2015. This plan has many advantages over the City’s original Wet Weather Management Plan: it's faster and cheaper; it’s greener; it’s more affordable; it’s more innovative; it’s better for our neighborhoods and our local economy; and it’s what our community wants.
