LEGEND: Cap Layer Material Excess Imported Fill In-Situ Topsoil (Soil and Rock in RO/RL Areas) Geotextile (Marker Strips RO/RL Area) Figure 4. Construction sequence. Step 1: Vegetation Removal - Commercial trees are salvaged. - Trees and shrubs along the channel are cut <strong>of</strong>f above ground leaving roots in place. - Slash is burned and placed near the bottom <strong>of</strong> fill, close to the soil resource. Step 2: Culvert Installation and Backfill - Reposition or modify large boulders within channel banks. - Geotextile and marker strips are placed in the channel. - Bedding fill is placed in the channel. - Fill is ramped accomodating culvert placement over channel grade control structures. - Bypass culvert is installed and backfilled. - Culvert area provides access for remaining pad construction. Step 3: Extend Geotextile and Marker Strips Up Slopes - Bright colored marker strips placed over rock/rubbleland soil surface (8' x 8' grid). - Geotextile fabric is placed over topsoil surface and extended up slopes. - Place 12" to 18" fill over geotextile for subsequent earthwork and operations. Remaining Native Fill Culvert Backfill/Bedding Material
LEGEND: Step 5: Cap Layer Material Step 4: Cut slope areas - Pull boulders from cutslope areas. - Boulders placed along culvert flanks and as fill where conducive. Topsoil Salvage - Salvage topsoil from Brycan, Midfork, Strych, and Rubbleland Travessilla soil units. - Transport topsoil, segregate and place in topsoil stockpile. - Salvage Rubbleland substitute topsoil and place in sedimentation pond embankments. Step 6: Excavate Sideslopes/Native - Fill Placed in Pad - Excavate sideslopes creating cutslopes above final pad elevation. - Native cut material used as pad fill and placed over culvert fill. - Place coal mine waste from portal highwall in designated area.
