Restore and Stabilize Hoover Creek for Flood Mitigation

Herbert Hoover National Historic Site » Restore and Stabilize Hoover Creek for Flood Mitigation » Document List

The National Park Service (NPS) is preparing an environmental assessment (EA) for the Herbert Hoover National Historic Site (NHS), for a project to restore and stabilize Hoover Creek for flood mitigation. The NHS is located at 110 Parkside Drive, West Branch, Iowa.

The project is needed to provide critical resource protection for the Herbert Hoover Presidential Library and Museum, other buildings and structures at the historic site, and the historic site landscape, as well as archeological sites. Implementation of the proposed project would provide the ability to better manage flood protection for frequent flood events within the NHS, with consideration given to natural resources and historic resources. The project would aid in the restoration of the riparian and proper functioning conditions along Hoover Creek in accordance with the General Management Plan/Environmental Impact Statement for the NHS.

Components of this project could include a flood storage detention basin, stream channel improvements to Hoover Creek, replacement of the Downey Street bridge for increased flood capacity, reconstruction of an historic retaining wall, and sanitary sewer relocation. In addition, excess soil from project work is being considered for use as sound mitigation berms in the reconstructed prairie, generally along Interstate 80.

The EA will be prepared in compliance with the National Environmental Policy Act of 1969 (NEPA), which requires that federal agencies analyze the impacts of their actions on the environment. The EA will evaluate impacts on park resources and values and identify mitigation measures to avoid or minimize the extent or degree of any impacts. During the initial planning process, the NPS has identified the following impact topics as having the potential to be affected: cultural landscape, archeology, stream/wetlands, prairie, fish and wildlife and visitor experience.

There will be two opportunities to comment formally on the project - once during project scoping and again following release of the EA. The NPS is currently in the scoping phase of the proposed project and will present an overview of the project at a public scoping meeting on July 12, 2018 from 6:00 PM to 8:00 PM at the park visitor center at 110 Parkside Drive, West Branch, Iowa 52358.
