This THP is SW of Weaverville, CA and adjacent to Douglas City, CA and Highway 3 at an elevation of 1,800 to 4,000 feet.  Sierra Pacific Industries is planning a clearcut tractor and cable logging operation on steep and unstable slopes in white fir, ponderosa pine, sugar pine and Douglas fir forests.  The THP area flows into the Trinity River which is listed as an impaired watershed for sediment and siltation.  There are unstable areas associated with units 3302, 3330 and 2240, and a fill failure has caused a road bed to drop down 5 feet in section 15.  SPI is planning to use ground based equipment on slopes up to 60% grade in areas designated for cable logging to construct fire lines, and construct and use roads, landings and crossings during the winter period.  They also are planning to construct segments of steep roads over 15% grade and/or pitches of steep roads over 20% grade in section 27.  Eight road drainage sites are planned for work including rocking, dip construction, ditch cleaning, and culvert repair/replacement.  Dudley’s rush was found in section 33.  There are 2 spotted owl nesting territories within 1.3 miles of the THP area.
