Ohio River Bridges Environmental Projects

Beginning in 1998 with the environmental phase, BLN's project team maintained open lines of communication with the public that has lasted throughout the current phase of the project. BLN performed the $22.2M Environmental Impact Statement and coordinated over 40 subconsultants during the environmental portion of our work.

Replacement of Putnam County Bridge No. 146

BLN developed the Categorical Exclusion environmental document and waterway permitting for this single-span Pratt thru truss bridge constructed in 1905, making it eligible for inclusion in the National Register of Historic Places. BLN closely coordinated environmental efforts for this project with the State Historic Preservation Office and was able to facilitate movement of the structure to the Canal County Wabash and Erie Canal Association Canal Park in Delphi, Indiana. The structure was disassembled, restored, and reassembled as a pedestrian bridge across the Wabash and Elis Canal to connect the County Historical Society Museum and old stone barn. BLN also worked with INDOT Office of Public Involvement to host the formal public hearings for the project. Client: Putnam County, Indiana

Vascular Plant Inventory and Asbestos Inspections at the Muscatatuck Urban Training Center (MUTC)

BLN developed a vascular plant inventory methodology and inventoried all terrestrial vascular plants that are present on the facility, which included 550 acres within the MUTC. BLN coordinated with the US Fish and Wildlife Service, Indiana Department of Natural Resources Division of Fish and Wildlife, and ensured compliance with the US Department of Agriculture. BLN conducted an extensive asbestos survey of many of the existing buildings at the facility. A number of these structures supported the facility when it functioned as an Indiana State Mental Health Facility.
