ODOT HAN-75-14.39 Bridge Replacement / Blanchard River Mussel Survey – Findlay, Hancock County, Ohio

As part of bridge replacement plans, STONE performed a mussel survey and relocation in the vicinity of the Interstate Route 75 Bridge over the Blanchard River.  An initial survey of the mussels at this location found 13 species of mussels in the vicinity of the bridge, including one species (Truncilla truncata) listed as a Species of Concern in Ohio.  All stream habitats (not just suitable habitats) were then visually inspected, with special attention paid to substrates that could support living mussels. Aquascope viewers were employed during the survey to aid in viewing the substrates.  In total, 637 live mussels were relocated following the Ohio Mussel Survey Protocols for Group 1 streams (USFWS & ODNR 2016).  These included no threatened or endangered species and four species of concern. The survey was conducted within a short time frame so as to fit within the approved field season (prior to October 1) and included coordination and approval with the Ohio Department of Natural Resources.

I am writing to thank you (Hank) and STONE for the services you performed for the site civil design (CC-plans and Site Compliance Plan), preparation of construction documents and specifications, and obtaining approvals through the City of Columbus for our new V&S Columbus Galvanizing LLC facility. Your ability to meet our tight schedule, stay within engineering construction budgets, and provide a quality end product was critical to the completion of the site work for this project.
