Temporary roads with winter limitations, and post cutter roads would have minimal effect on soil 

 displacement but could result in compaction. Impacts for temporary local could result in 50% 

 growth reduction on the travel way for the life of the stand but represent less than Vi percent of 

 the project area. Following use, temporary roads would be closed and have long-term drainage 

 features installed and reseeding with grass. 



Road reconstruction would be similar for all action alternatives (2.18 miles). Existing access 

 roads can be used as is with some localized repairs, minor relocation and maintenance. A road 

 inventory of required repairs, improvements and maintenance needs will be completed for the 

 chosen alternative. Road drainage would be installed concurrent with new road construction and 

 will be maintained. 



Road use will be limited to relatively dry, <20% soil moisture, or frozen conditions to maintain 

 drainage and road improvements and reduce road costs. Segments of roads will be graveled, 

 such as stream crossings and segments of road that cross-clayey soils that severely limit season of 

 use. The gravel source required for road construction would be designed to remove less than 1 

 acre out of timber production. Source area would be located on a dry site of moderate slopes and 

 would require prompt revegetation in accordance with reclamation law. 



Alternative B & C 



These alternatives would both construct about 5.06 miles of new road extending from an existing 

 forest service system road. Between . 1 and .3 miles of temporary road would be designed with 

 minimal excavation and stabilized after use. Reconstruction would maintain or improve drainage 

 on 2.18 miles of existing roads. 



Timber harvest would be completed by conventional ground skidding, and post and rail harvest. 

 Alternative C would have about 35 1 acres of additional low intensity harvest (post and pole 

 thinning) than Alternative B. post and rail harvesting would have negligible ground disturbing 

 effects on soils (estimated at 10% of area treated) and presents low risk of erosion as long as 

 standard harvest mitigations for skid trail spacing and season of use are implemented. Tractor 

 harvest units would likely incur similar ground effects as the other action alternatives on a 

 proportional basis. With action alternatives B and C, the eroded irrigation gully would be 

 reshaped and stabilized with grass and shrubs to reduce chronic erosion and sedimentation into
