North Bank Lane Rises
Lower North Bank Lane was closed to traffic this week to facilitate rising of the road grade at Redd Creek. A continuous stream of double dump trucks and single belly-dump trucks delivered nearly 600 loads of fill material raising the road bed approximately 7â€™. On Thursday and Friday the 10â€™ culvert was placed in the road fill at the historic stream location of Redd Creek. The culvert is sized to allow 3â€™ of streambed material to be placed in the culvert providing a natural streambed for passage of anadromous fish such as coho salmon and cutthroat trout. Redd creek is currently channelized to the west side of the floodplain with a small culvert inhabiting fish passage. A new sinuous stream channel will be excavated to the culvert and the stream diverted into the new channel later in August. On Friday, Tidewater Contractors shifted their focus to begin the initial efforts to raise North Bank Lane near Fahys Creek.
Knife River Corporation continued digging new tidal channels and filling agricultural ditches. A second crew was brought in this week, but equipment breakdowns slowed the effort to a single crew much of the week. Technical issues with the transmission line boring brought this effort to a halt much of the week, but on Friday the issues were resolved and the boring continued. The east bore emerged on the hill above the south bank of the Coquille River on Friday and back reaming of the bore is underway.
