An unnamed tributary of the South Papillion Creek was experiencing substantial bank erosion and stream down-cutting. The bank erosion had removed 15 linear feet from the east side of Outlot C and was encroaching on other lots within Cedar Hollow.
Description
The site consisted of approximately 190 feet of stream length within Outlot C of the Cedar Hollow residential development. A sheet pile retaining wall was placed along an eroded section of collapsed bank along the east side of the stream. E&A also installed two sheet pile weir structures within the stream for channel stabilization, placed soil fill between the sheet pile weir structures and installed flex matting above the soil fill between the weir structures. The U.S. Army Corps of Engineers required a Nationwide Permit for impacts to 190 linear feet of jurisdictional stream.
