Testimonials
“The Ohio Stormwater Conference is a perfect example of the power of convening professionals across Ohio to network, learn, and share insights on the most significant challenges and the most innovative and effective solutions of stormwater management. Over the nearly two decades since this conference began, it has grown to be one of the largest statewide conferences for environmental and engineering professionals and continues to be a reliably good opportunity for knowledge sharing and inspiration. Nowhere is this more important than in the Great Lakes region – home to the largest source of fresh water on earth, making quality of surface water paramount.”

“The Ohio Stormwater Conference consistently brings together more than 900 attendees, with a strong concentration of decision-makers—city engineers, service directors, county engineers, and representatives from conservancy and sewer districts. It’s the largest stormwater conference east of the Mississippi, with broad representation from Ohio municipalities, counties, and state agencies including ODOT, Ohio EPA, and ODNR. What truly sets the conference apart is the networking and culture. The environment is collaborative and approachable, with a long-standing emphasis on knowledge sharing without ego. Presentations are accessible and downloadable, and agencies and consultants genuinely work together toward cleaner water and better stormwater solutions.”

“The Ohio Stormwater Conference is a premier event—not just in Ohio and the Midwest, but one of the best stormwater conferences in the country. There is no other conference nationwide that offers a technical program with such breadth and depth. The number of attendees from multiple states across the U.S. is a testament to the conference’s quality. I’m very proud that such a respected conference is hosted in Ohio, where I’m from.”
