Tait Station Dam Removal

Mitigation planning during dam removal on Great Miami River

Cardno’s full-service expertise in restoration and mitigation services paved the way for the approval of the Tait Station Dam Removal Project, helping enhance aquatic and riparian habitat, improve water quality, and increase recreational use of the Great Miami River in southwest Ohio.

In 2017, the Tait Station Dam Removal Project was conditionally approved by the U.S. Army Corps of Engineers (USACE) as a permittee-responsible mitigation solution for unavoidable stream impacts associated with roadway improvements in southwest Ohio.

Based on Cardno’s water resources modeling, mitigation planning and design engineering, ODOT received the USACE approval for the project as a ‘pooled’ stream mitigation site. This enabled ODOT to secure over 9,400 linear feet of stream mitigation credits, an estimated market value of $2.6 million.

Currently under construction, the dam removal project is being performed on the third largest river in Ohio and is expected to provide significant ecological lift, attainment of water quality goals, and enhancement of aquatic functions and services in the Great Miami River.

The project also eliminates an eminent threat to public health and safety by removing the dam and its legacy infrastructure so that the river can also meet its intended recreational use: navigation.

Cardno is performing the project as a full-delivery mitigation solution. Cardno’s services have included modeling, mitigation planning, design engineering, permitting, construction administration/oversight and final restoration.

Cardno is also tasked with providing five years (2018-2023) of post-construction compliance services, which includes physical and biological monitoring of the restored river reach.
