∗ Alternatives for deciding official to consider: No Action – No Treatments. Proposed Action – Reconstruct segments along five
miles of Road 233, near the current location, to reduce failure potential and sediment input to Crooked River.
Relocate Road 233 upslope out of 100 year floodplain between milepost 2 and 6.
Relocated road access from Road 233 onto Roads 1803 and 522, along Deadwood Creek. Convert to trail or decommission Road 233.
![Page 33: Crooked River Valley Rehabilitation Projecta123.g.akamai.net/7/123/11558/abc123/forestservic... · 2015-06-09 · Scoping Presentation January 2013 . ... Full size vehicle access](https://reader033.fdocuments.us/reader033/viewer/2022050412/5f893275e38cfd4ee6032988/html5/thumbnails/33.jpg)
Narrows Road – Proposed Action
Primary elements of the proposed action: ∗ Keep road grades at 5 % or less. ∗ Create 100 year stream flow width of at least 70 feet, except
where the original valley width is less than 70 ft. ∗ Use competent rock excavated from the cutslope for fill,
subgrade, and riprap material to reduce hauling, where feasible. Use excess material to raise the road surface elevation of Road
233 from milepost 6 to its junction with Road 522, near Relief Creek.
∗ Move the centerline of the reconstructed road to minimize cutslope excavation, where feasible.
