1 ODOT Programmatic ESA Consultation on the Federal-Aid Highway Program (FAHP) User’s Guide Training, June-July 2013 Bank Stabilization Streambank or channel stabilization. The following streambank stabilization methods may be used individually or in combination:

2 ODOT Programmatic ESA Consultation on the Federal-Aid Highway Program (FAHP) User’s Guide Training, June-July 2013 Streambank Restoration Primary Goal: Restore ecological function in riparian and floodplain habitats Planting or installing large wood, trees, shrubs, and herbaceous cover. Include large wood in each streambank restoration action when appropriate to the system, and to the maximum extent feasible. Large wood must be intact, hard, and undecayed with intact rootwads

3 ODOT Programmatic ESA Consultation on the Federal-Aid Highway Program (FAHP) User’s Guide Training, June-July 2013 Biotechnical streambank stabilization methods, an engineered log jam, or avulsion prevention techniques may be used without restriction.

4 ODOT Programmatic ESA Consultation on the Federal-Aid Highway Program (FAHP) User’s Guide Training, June-July 2013 Vegetated riprap with large wood may be used where a qualified engineer determines that biotechnical streambank stabilization methods will not provide an acceptable factor of safety.

8 ODOT Programmatic ESA Consultation on the Federal-Aid Highway Program (FAHP) User’s Guide Training, June-July 2013 The amount of rock used must be limited to the minimum necessary to protect the integrity of the structure and, whenever feasible, include soil and woody vegetation as a covering and throughout the structure. (Page 27-28)

9 ODOT Programmatic ESA Consultation on the Federal-Aid Highway Program (FAHP) User’s Guide Training, June-July 2013 Unvegetated riprap: Fill a local scour threatening a culvert, road, or bridge foundation. Stabilize a footing, facing, head wall, or other structure necessary to prevent scouring, downcutting, fill slope erosion, or other failure at an existing culvert or bridge.
