DRG Engineering Restores Floodplain In Boardman, OH Watershed

Boardman Township, OH

DRG provided surveying, engineering, and construction management services for four flood hazard mitigation projects in the Cranberry Run Watershed of Boardman Township, OH.

A Flood Of Challenges

Davey Resource Group, Inc. (DRG) surveyed, engineered and managed construction for four flood hazard mitigation projects in the Cranberry Run Watershed. The highly channelized stream in a Boardman neighborhood caused flooding during heavy rains. Grant funding allowed the township to purchase floodplain properties, and DRG designed an ecological restoration for flood reduction. Boardman received funding from a FEMA Flood Hazard Mitigation Grant.

A Detailed Approach

The design focused on specific parcels, requiring the engineering team to create flood storage without expanding the project area. Limited haul-off due to grant funding necessitated minimal excavation. A grading plan for five sites allowed the stream to access its floodplain during rain events. A landscaping plan used native plants for low maintenance. Floodplain storage and wetland habitat mitigated downstream flooding. The design included removing and replacing an existing dam with a naturalized stream channel. DRG assisted in contractor selection and provided construction oversight.
