Wpct Farm Rpcprvnirc Bank Arrnnrina Plan <br /> Reservoir Bank Armoring. <br /> Armoring will be placed inside of the mined areas adjacent to the <br /> South Platte River channel in Phase 1 & 2 . In Phase 1 the top of <br /> bank into the reservoir is more then 400 feet away from the <br /> mining line except on and approximately 1305 Fees section that <br /> is approximately 347 ' from the river and is protected from direct <br /> flooding flow by the old railroad embankment . This section will <br /> be armored as mining progresses thru Phase 1 . The small section <br /> in Phase 3 is above the Flood Plain so will not be impacted by <br /> flooding. The armoring will be placed on the slopes starting <br /> from the existing ground surface elevation. The toe of the <br /> armoring will be a minimum of 5 feet below the river thalweg, <br /> have a 3h to lv slope and will be 2 feet or more thick. This <br /> will require approximately 2 .35 cyd/lft along the excavated bank <br /> slopes . Once sloping begins, the armoring will be installed on <br /> 1, 000 foot sections until completed. This will leave an armored <br /> face along the top of the bank and the slope into the reservoir <br /> that is 35 feet wide. <br /> Supplied supporting documents <br /> Figure 1 - Bank Protection Plan cross section <br /> Safety factor calculation page <br /> LGE-WEST FARMS RESERVOIR May 2023 <br /> 115 <br />
