Document Description
The project is limited to the demolition and removal of existing gabion baskets, occupying approximately 168 square
feet or riparian habitat, and replacement with rock slope protection (RSP) consisting of the native river cobble that is
currently within the gabion baskets. Adjacent existing cobble-covered slopes will be interplanted with willow (Salix
sp.) stakes to revegetate approximately 453 square feet of the riparian area. As part of the project, approximately
eighteen 3.5-inch diameter steel pipes will be driven using hand tools into the bank and cut above grade six inches
or less to support a removable seasonal access aluminum staircase and ramp. The project will result in
approximately 168 square feet of temporary impacts to the riparian habitat from the removal of the gabion baskets.
Approximately 453 square feet of riparian habitat will be revegetated with willow stakes to offset the temporary
impacts. Of the 168 square feet of habitat where gabions will be removed, approximately 98 square feet will be left
unvegetated to allow for seasonal placement of the staircase and ramp, therefore there will be no new permanent
impacts. No grout will be used to install the pipes. Access and staging will occur via existing roads and developed
areas. No trees will be removed as part of this project.
