Forest Service road construction occurred in conjunction with timber harvest activities within the watershed, primarily during the 1960's to 1980's.  Stream crossing culverts installed at that time were often undersized, and are now reaching the end of their functional life.   The project will involve removal of the 48" culvert present at MP 16.1 and replacement with a 96" culvert. The current culvert is eroding at the outlet, leading to a large scour hole that is destabilizing the embankment. The risk to this site of continued failure of the slope could trigger a slide to the Sitkum River, which can be seen from the road at that culvert. If this pipe fails due to it's deteriorated condition there is direct delivery potential to the river below.  The culvert is also undersized in proportion to the bankfull width of the streams, and does not allow normal transport of wood and sediment, and lacks capacity at flood flows.  The expected trends on the Olympic Peninsula due to climate change include increased winter precipitation and increased flood frequency and magnitude from intensified heavy rain events (Halofsky et al. 2011).  In present condition, the site is vulnerable to expected increases in flow associated with climate change.
