NCD-1, 2 2 N/A N/A N/A None 1. Trees must be felled and yarded away from all riparian features (e.g. streams, NCDs) where practicable. 2. Keep machinery at least 5m away from all riparian features. 3. All natural drainage patterns (including all NCD’s, streams, dry swales, roadside ditching) should be maintained and left free of excess debris (slash or soil) that could result in
a redirection of seasonal surface runoff. Safety Highlights: Steep Slopes: HU 2, and parts of ground-based area (HU 1), exceed 35% side slopes. Limit machine use on slopes as per WorkSafe BC OHS regulation Part 26-16 (slope limitations). A steep slopes map has been provided showing areas of the block with slopes >35%. Rock Fall Hazard: Where workers are required to be down slope of steep slopes, appropriate measures must be taken to reduce the risk of impact from loose rock or minor rockfall, which may occur naturally or as a result of disturbance from harvesting operations. Potential Public Use of Road System: The road system associated with this development is used by hunters, campers, hikers, other recreationalists and local residents. Place signs at the start and end of the block during harvesting that indicate active harvesting. Operations must be conducted to ensure the safety of the public using these road systems. Discuss public use of the roads during the pre-work.

Harvesting Recommendations from Terrain Stability Assessment, Lendrum-Woodbury Creek (CP 407) Overview Assessment report by Perdue Geotechnical Services (June 26, 2018):
• Ground skidding across natural drainage paths and surface watercourses should be avoided. If this cannot be avoided, harvesting should be conducted during the drier months of the year, on a compressed snowpack, or effort made to ensure timber is skidded butt-first to minimize potential ground disturbance within such drainage features.
• Timber harvesting should not be completed during excessively wet conditions, such as during the freshet and/or prolonged, heavy periods of rainfall. • A post-harvest inspection should be completed to ensure all natural drainage patterns have been maintained. Logging debris should be removed from the wetted
perimeter of all watercourses and subtle drainage features to ensure an accumulation of coarse woody debris or site degradation from logging operations does not result in a drainage diversion. These measures include ensuring the drainage network along permanent roads remains functional, as intended.
• Temporary access trails may be built using debris-supported fill slopes (where required) to reduce cut bank excavation and the potential for groundwater interception. Drainage control measures must be implemented to ensure all natural drainage paths are maintained. All trails must be fully rehabilitated concurrently with the completion of the proposed timber harvesting. If harvesting is to be conducted during winter months, trails must be seasonally deactivated prior to the freshet by out-sloping where practical and installing cross ditches to maintain natural drainage patterns.
Spur 1: See Terrain Stability Assessment report above for general Road Recommendations. Road Information:
This road is considered permanent (>2 years).
• Spur 1 This road is 1+422m in total length. There are 3 (three) proposed 450mm culverts within block 1 @ hubs 4, 17, and 31.
