This THP is located between the Eel and Van Duzen Rivers just north of Rio Dell/Scotia and Highway 101 at an elevation of 80 to 1,500 feet.  Green Diamond Resource Company is planning a tractor and cable logging operation on steep and unstable slopes in redwood, Douglas fir and grand fir forests.  The THP area drains into the Van Duzen River which is listed as an impaired watershed for temperature and sediment.  There are 7 landslide terrain sites including 2 shallow rapid landslides near class II (mid sized) and class III (intermittent) watercourses, a headwall swale in unit A; 2 shallow rapid landslides and a deep seated landslide near class II watercourses in unit B; and a complex landslide including a debris slide near a class II watercourse in unit C.  Green Diamond Resource Company is planning to use ground based equipment in areas designated for cable logging in unit A, and re-const 3 segments of existing road inside a class I (year round) watercourse.  Multiple sections of steep road are proposed including 800 feet of road exceeding 15% grade in unit B, 150 feet of road exceeding 20% grade is proposed in unit B, and 3 segments of road is proposed exceeding 15% for over 200 feet but less than 500 feet in length.  56 road drainage sites are planned for work including rocking, dip construction, culvert repair/replacement and restoration of washed out crossings including fill failures and sinkholes.  There is an osprey nest .21 miles SW of unit B, and spotted owl nesting territories are located within .25 mi of unit C, and .5 mi of unit B. More information is available on the THP Tracking Center website.
