Section 961.5 - Logging Practices

(a) Tractor logging and tractor preparation of tree layouts shall not be permitted on slopes averaging over 50% unless it can be shown that tractor logging will result in less soil disturbance than would result from an alternative method.

(b) Roads shall be single lane, and generally the travel surface shall be no more than 12 feet (3.67 m) in width, except where alignment, safety, and equipment necessary to conduct the operation requires additional width. Deviations shall be explained and justified in the plan.

(c) An RPF may obtain a relocation of the main skid trails from that shown on the approved plan if the Director concurs after an inspection on the ground. Such relocation may be treated as a minor deviation with the plan so amended.

(d) Roads shall not be constructed through slide areas or areas with visible evidence of slope instability unless the alignment is the best available alternative and special design features are incorporated in the plan. There shall be provisions in the plan to maintain the design features or provisions to maintain or improve the stability of the area after completion of the use.

(e) Roads, landings, cuts and fills shall be screened from direct view to the extent feasible by leaving screen trees and other vegetation between the disturbed areas and public areas utilized by substantial numbers of viewers.

(f) Soil disturbance, other than that incident to necessary road maintenance, whether with tractor or by cable means, shall not occur under excessively wet ground conditions that could result in substantial soil compaction and erosion.
