Restore and Stabilize Hoover Creek for Flood Mitigation Environmental Assessment

An Environmental Assessment for the Restore and Stabilize Hoover Creek for Flood Mitigation proposed project is now available for comment.

The National Park Service proposes to restore and stabilize Hoover Creek for flood mitigation at the Herbert Hoover National Historic Site (NHS). This 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. This 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 includes 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 will be used to create sound mitigation berms in the reconstructed prairie that will help dampen sound along Interstate 80.

Through February 18, 2019 the public is invited to share their thoughts on the project. You may download a copy of the Environmental Assessment, which describes the project. We invite you to comment on this Environmental Assessment during the 14-day public review period.
