Baldwin Creek
Dam Removal and Fish Passage Restoration, Design and Construction
Project Overview
NTH led a multidisciplinary team of engineers, biologists, geologists, and environmental scientists with this important project. The project involved demolition and removal of three low-head dams along the channelized stream, design of in-stream rock control structures to maintain stream stability, and vegetating the stream bank and rock slopes along the stream.

Project Scope
The design team firms and their roles on the project included:
  • NTH Consultants (lead firm on design, engineering, and other contract/bid documents)
  • Davey Resource Group (Ecological Assessment, permitting, design, support and construction documentation KS Associates (Surveying and sediment/erosion control management)
  • The Ohio State University (modeling and design consultation).

The project included field investigation and surveying, stream flow and fish-passage modeling, engineering design for the removal of the three dams and compensation for absence of the dams with in-stream rock-riffle structures. The in-stream structures help maintain stability of the stream bed load and control sloughing of the streambank.

After a bidding process, Mark Haynes Construction was selected to complete the construction, largely because of their experience in completing similar challenging stream restoration projects and their specialty equipment that enable them to access the three dam locations.

Construction management activities by the NTH team included:
  • Collaboration with Mark Haynes Construction during construction to address requests for information and/or adjustments from the design, and to help maintain the project schedule
  • Inspecting and observing activities to assure compliance with the contract documents
  • Preparing daily field reports to document the construction activities
  • Reviewing and processing submittals and change order requests
  • Inspecting construction best management practices for compliance with the Stormwater Pollution Prevention Plan (SWPPP); and tracking quantities and reviewing contractor invoices to be sure the invoiced pay quantities were correct
