Hancock Park District Oakwoods Nature Preserve Wetland Restoration

HANCOCK PARK DISTRICT

Oakwoods Nature Preserve Wetland Restoration Project

Findlay, Ohio
Funded by the ODNR via H2Ohio
Flooding during construction shows the stormwater storage and treament benefits of the project
Floodplain wetlands were excavated throughout the site
Western chorus frogs and other amphibians began using the shallow excavated wetlands in early spring 2021

Hancock Park District is implementing a wetland restoration project, funded by two H2Ohio grants totaling approximately $1.4 million, at the Oakwoods Nature Preserve. The project site is a 125-acre area, the majority of which had been farmed for many years and was drained by an extensive series of subsurface drain tiles. Coldwater assisted with the completion of the grant applications and was responsible for site assessment, permitting, design, bid assistance, and construction management services.

Currently, sediment and nutrient loadings into western Lake Erie from the Maumee River watershed occur at very high levels.  The project is designed to improve water quality within the Maumee River watershed by retiring marginal farmland, restoring riparian floodplain wetlands, and enhancing riparian buffer along Aurand Run.  Upland buffers and native prairies will be planted to protect the restored wetlands and an adjacent forested wetland. Water quality will be improved through interception, detention, and assimilation in restored floodplain wetlands; infiltration; and uptake of nutrients in wetlands, woodlands, and prairie.

The project will serve as an important model for demonstrating how to more effectively manage agricultural runoff to reduce phosphorus and other nutrients in surface runoff and tile drain water. Repurposing and retiring marginal cropland will serve to improve water quality while at the same time helping to maintain drainage that is needed to sustain farming in northwestern Ohio.

Plant diversity will be restored throughout the Site by seeding and planting herbaceous and woody species in the floodplain, wetland, and adjacent buffer areas. The plantings will include native wetland plugs, live stakes, shrubs, and trees. Throughout the restoration area, approximately 8,000 plugs, 1,100 trees, 1,100 shrubs, and 3,500 live stakes will be planted in fall 2021.

Coldwater is providing construction management services for this on schedule and on budget project. Project construction will be completed in December 2021.
