SUSTAINABLE SOLUTIONS FOR YOUR WATER RESOURCES
The Hyponex Corporation, a subsidiary of the Scotts Miracle-Gro Company, operates a soil-excavation facility near Shreve, Ohio. Much of the site supports wetlands along Kiser Ditch. Unfortunately, the historical promotion of ditching, draining and planting of reed canary grass, a non-native and invasive species in Ohio, has caused these wetlands to deteriorate to a low-quality condition. Coldwater developed a permitting, mitigation, and post-construction monitoring strategy for the next phase of operation, which includes approximately 25 acres of additional soil excavation from existing, low quality wetlands. The mitigation plan includes all on-site mitigation, saving the client from purchasing off-site mitigation that could have cost over $1.5 million. The site has developed into a wildlife haven and serves as an important wildlife corridor between the Funk Bottoms Wildlife Area and Shreve Lake. The site is used by bald eagles, trumpeter swans, sandhill cranes, ospreys, teal, grebes, mallards, harriers, kestrels, kingfishers, mergansers, and many other bird species. Coldwater also assisted Hyponex with expansion of the Pre-Pack product storage area at the facility. Coldwater designed construction-phase best management practices (BMPs) and permanent stormwater management controls, obtained a stormwater permit from Wayne County, and updated the existing Ohio EPA general industrial permit Storm Water Pollution Prevention Plan. The final design for the project incorporated a grass filter strip and bioretention swale for effective, low-cost storm water runoff treatment.
