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.

“STONE is an instrumental part of our team on the Portsmouth By-Pass Project: the 16-mile new construction project, which is the single largest project in ODOT history. This project has come with more than its share of environmental challenges. STONE has delivered over 30 full environmental clearance reviews and reports we have requested as part of the project, handling them from start to finish in a very timely & cost effective manner. Furthermore, they’ve proven themselves as an extremely valuable resource when it comes to consulting on mitigation efforts, hazardous materials, and resolving various unknown environmental situations that the project has encountered.

 

From the top down STONE has proven they are committed to excellence and we look forward to working with them on many projects in the future.”
