THP 1-17-001 DEL (Tube Road THP) Green Diamond Resource Company, 276.8 acres; 49% clearcut, 23% commercial thin, 19% no-harvest, 6% selection, 2% roadside, 1% special logging.  McGarvey Creek (HUM: T13N R1E Sec.27, 28, 33, 34).  Wet weather operations, moderate erosion hazard, steep slopes up to 65%, steep roads, landslide terrain, road failure sites, 13 road drainage work sites, impaired 303.d watershed, herbicides, oversized units, redwood national park, coho watershed, spotted owl, marbled murrelet, osprey, tailed frog, trees up to 48" dbh.  Estimated public comment deadline: 02/20/17. VIEW

This THP is about 2.5 miles south of Klamath, CA near Highway 101 and the eastern boundary of Redwood National Park at an elevation of 320 to 800 feet.  Green Diamond Resource Company is planning a mostly clearcut tractor and cable logging operation on steep and unstable slopes in redwood, western hemlock, Sitka spruce and Douglas fir forests.  The THP area flows into the Klamath River which is listed as an impaired watershed for sediment, temperature, dissolved oxygen and nutrients.  A Special Treatment Area (STA) will be located inside unit D within 200 feet of Redwood National Park to hide the effects of clearcutting. There are 17 unstable areas in the THP area including; 1 shallow rapid landslide terrain site in the SW portion of unit B, 1 shallow rapid landslide terrain site in the eastern portion of unit C, 8 shallow rapid landslide terrain sites in the NW portion of unit D, 1 deep seated landslide terrain site in the northern portion of unit E, 2 shallow rapid landslide terrain sites near haul roads in unit F, 1 shallow rapid landslide terrain site on the fill slope of a haul road near Highway 101, and 3 shallow rapid landslides on a road cut adjacent to Highway 101.  Multiple road failure sites exist in the THP area including fill slope failures, cut bank failures, bank sloughing, gullying and erosional voids near crossings.  Green Diamond Resource Company is planning to use a segment of existing temporary road between two class II (mid sized) watercourses for loading and decking operations inside unit D, and construct a steep seasonal road over 20% grade, and construct a temporary road in unit D which may exceed 15% grade for over 200 feet.  They also want to construct a seasonal road within 150 feet of a class I (year round) watercourse, and construct another temporary road inside a class II (mid sized) watercourse in unit D.  13 road drainage sites are planned for work including rocking, dip construction, ditch cleaning, culvert repair/ replacement and restoration of washed out crossings and sink holes.  Two historic osprey nests are adjacent to Highway 101, and within .25 miles of two permanent haul roads, and tailed frogs are known to occur in or immediately adjacent to unit H.  Marbled murrelet habitat is located on Prairie Creek Redwoods State Park lands within .25 miles of several seasonal and permanent haul roads, and on Green Diamond Resource Company lands within .25 miles of the MG-170 Road.  A spotted owl nesting territory is located within .5 miles of units C and F.
