MAP OF AREA
Area 1
This area will be wet mined, and backfilled with sand spoils
from this area and other mining areas of the property. There
will be no import of material for backfilling from out of the
permit area. Approximately 8,000 cubic yards of
topsoil /overburden will be stored and temporarily revegetated
in the 251 setback area along the east side of this area and
the south side of Area 2B for later permanent revegetation.
No mining into the water table will be undertaken, until a
temporary augmentation plan has been approved.
Area 2A
The South Platte River channel improvements will be installed
in the areas shown on the accompanying map as soon as the
relevant approvals are obtained. The present plan calls for
removal of the existing berm along the southern portion of
this area, installation of two riprap trenches, and
installation of a grade control structure.. The slurry wall
along the River will be installed behind (east and south) of
the rip rap trenches and grade control structures. The exact
location and alignment of these improvements are conceptually
shown on the MINING PLAN MAP, EXHIBIT C -2, but will be exactly
determined by final engineering and approval of UD &FCD. No
mining will occur in this area, until UD &FCD and any other
relevant approvals are obtained.
Area 2B -
Approximately 8,000 cubic yards of topsoil /overburden will be
stored and temporarily revegetated in the 25' setback area
with the stored material from Area 1 for future later
permanent revegetation of the banks and periphery areas of the
future reservoir. This topsoil /overburden storage will remain
until the end of mining to act as a permanent reserve for
revegetation. However, as much as possible, topsoil /overburden
will be immediately used in previously mined areas to build
the required slopes of the reservoir and for revegetation of
the banks /periphery areas. Topsoil /overburden may also be
temporarily stored on the future berm along the South Platte
River outside of the South Platte River floodway, and /or in
other 251 periphery setback areas.
Area 2C -
Approximately 55,0001 cubic yards will be stored along the
south 251 setback of that area to potentially revegetate the
entire 341 acres of Area 2C, although this area will be filled
with sand spoils as much as possible. This topsoil /overburden
storage areas will remain to the end of mining to act as a
permanent reserve for revegetation. In the worst case, if
approvals haven't been obtained for wet mining on Area 1, for
the slurry wall, and for construction of channel improvements
in Areas 2A and 2B, mining to the water table may be initiated
in this area while the relevant approvals are being obtained
for the above items.
