but at an adequate distance away from the crossing to provide for effective 

 sediment filtering. 



• Clean the inlets and outlets of culverts. Implement additional sediment 

 mitigation measures where necessary. 



• Contain any fuel storage for helicopter operations to prevent spillage and 

 located on a stable site away from surface waters or drainages. 



• Monitor road drainage conditions as part of the on-going project operations 

 and make repairs as needed, including culvert cleaning and re vegetation. If 

 cutslope or fillslope slumps occur on existing roads, stabilize to control 

 erosion as part of the harvest project. 



Site-Specific Design 



• Down Woody Material: During harvest operations, retain five to ten tons per 

 acre of woody material larger than 3 inches diameter scattered throughout the 

 sale units. On old harvest areas and low tree volume sites where 5 tons is not 

 possible, retain all available slash on site. On slopes over 30% retain all slash 

 on site by log length skidding or whole tree harvest if tops are left on site. On 

 slopes less than 30% whole tree harvest would be allowed when 90% of all 

 slash is return skidded or left within the harvest unit. Slash should be returned 

 from the landings back into the harvest unit as it is created and well 

 distributed, evenly throughout the unit. Large amounts of slash shall not be 

 allowed to accumulate at the landings before it is returned in the unit. 



• Skyline Yarding: Where cable harvest is required, log length harvest is 

 preferred and tree length harvest would be allowed if the tops are left on site. 

 Where ever possible skyline yarding sets would be located on ridges or 

 convex slope sites to promote corridor locations that disperse water and avoid 

 pulling logs up draws or concave spots that could concentrate runoff and 

 erosion. Leading end of the logs would be carried free of the ground at all 

 times except during lateral or downhill yarding. 



• Install and maintain adequate erosion control in harvest units, skid trails and 

 cable corridors as needed concurrent with operations. Steep disturbed areas 

 would likely require a combination of waterbars and mulching with slash or 

 straw, filter fence, and grass seeding due to the lack of fine slash and foliage 

 following the fire. Where slash is used, the slash must be in good contact (may 

 require lopping) with the ground to be effective. Erosion control shall be 

 completed prior to acceptance of skidding operations by the Forest Officer. 



• 



Fell trees for erosion control as directed. To control erosion on severely 

 burned slopes over 30%, 10-20 submerchantable trees per acre (or as needed 

 to provide adequate coverage) would be retained, felled, or aligned
