'A culvert is in place between NHN-001 East Segment 1 and 2 and Segment 5 and 6. Culvert designs are presented in the East Ditch SEDCAD demonstration.
2All segments for which SEDCAD requires riprap lining will be lined with Geoweb filled with 3 -inch minus rock. This is based on information from the
"Comparison of Geoweb to Rip -Rap" section of the Geoweb Cellular Confinement System Information Sheets on the following pages.
