NOTES:
1. UTILIZE SLASH FROM ADJACENT NEW TRAIL CONSTRUCTION TO COVER EXISTING SECTION TO BE OBLITERATED.
2. SLASH CONSISTS OF LOGS, LIMBS, BRUSH, AND ROCKS PLACED IN A WAY TO CATCH SEDIMENT MOVEMENT.
3. SLASH TO BE SPREAD RANDOMLY ACROSS TRAIL BED. DO NOT SPREAD PARALLEL TO TRAIL SURFACE.
4. LIMB ALL TREES AND SHRUBS AND TAMP SLASH INTO GROUND SO THAT MOST OF THE SLASH IS IN CONTACT
WITH THE GROUND.
5. DRAINAGE DIPS WILL BE STAKED IN THE FIELD WHEN REQUIRED AND WILL BE PAID SEPARATELY UNDER
SECTION 927.
