Road Systems

Main National Forest System Roads

NFSR 071.B, 071, and 071.A spurs adjoin this road (primarily closed ML1 spur roads) and are located behind a gate at the Baldy Mt. trail head. A trail system exists along these roads which sees moderate traffic from mountain bikers, hikers, and runners.

Temporary road construction of at least 0.55 mile will be needed for this sale due to the access of the unit 7, all temp roads will begin off NFSR 071.A. There may be more temp roads created with the authorization of the

COR.

Unit Description:

Unit 1 has an average skid distance of 590 feet although there may be longer skids included. The bottom half will require adverse/uphill skidding due to the topography of the unit. There is an intermittent stream located on the western edge of the unit.

Unit 2 may require uphill skidding although it could be avoided depending on logging techniques. Skid length averages around 470 feet, with a cliff ending the unit to the west.

Unit 3 is a elongated south to north unit with a skip section towards the north. Skids should take advantage of the relatively light topography in the unit.

Unit 4 is a larger unit that could use a temp road if desired. Adverse skids could take place although the topography could be used to benefit outcomes.

Unit 5 is the smallest unit with a dozer line gap between units 5 and 6. There is significant regen in the dozer line that should be avoided as best as possible with COR guidance.

Unit 6 has a gap between units 5 and 6 that is a former dozer line with significant regen. The dozer line that should be avoided as best as possible with COR guidance.

Unit 7 will require a temp road in order to gain access. There will be adverse skidding and hauling due to the private boundary at the south of the unit and the road system that is in place.

Piles shall be located outside the drip line of residual trees, and reasonably free of soil and duff to facilitate burning. Piles shall not be located on improvements or within protected areas. Excavated stumps and root balls shall not be placed in slash piles.

LOP/SCATTER: Long butts and slash not piled shall be scattered evenly throughout cutting units, as practical, to a depth of no more than 2 feet. This material may be deposited on skid trails, landings, temporary roads and other disturbed areas as directed by the Forest Service. Bark depths at landings shall not exceed 4 inches.

FELL DAMAGED SMALL TREES: Trees not meeting utilization standards, damaged beyond recovery, shall be felled, and treated as slash.
