In order to accomplish the corrective actions required, Sierra determined the roadway
needed to be re-contoured so that the surface sloped into the hillside. This needed to be
done from the portal down to the area known as "Quarry Town," a distance of
approximately 800 feet. Sierra hired KSLAB Construction to perform the work. The
photos below show the road work shortly before completion.
KSLAB cleaned out most of the rnazble fines that had been placed along the outside edge
of the road by Sierra and transported it up to the marble waste pile to the south of the
portal. KSLAB re-set some
of the jersey barrier that had
fallen over the hill along the
outside edge of the road, and
used appropriately sized
mazble blocks to set along
the outside edge ofthe road
as well. This provided a
basin between the outside
and inside edges of the road
within which fill could be
placed to build up the
appropriate slope into the
hill.
KSLAB brought approximately 300 cubic yazds of fill material from Mud Gulch to build
up the outside portion of the road. Mud Gulch is located approximately'/, mile north of
the quarry along the public access road. This material had accumulated on the uphill side
of the culvert at Mud Gulch as a result of snow slide and storm water erosion. Periodic
clean out ofthe culvert intake over the yeazs since the quarry opened (1990) resulted in a
large stockpile of this material at Mud Gulch. The material consisted of Mancos Shale
rubble, 20% +12 inch boulders, 20% +2" rocks, and 60% fines. Sierra has maintained the
public road from Mazble to the Yule Quarry under standazds set by the Gunnison County
Land Use Change Permit for the quarry operation.
Sierra purchased approximately 1500 yazds of road base gravel from Roaring Fork Sand
and Gravel in Cazbondale and had it trucked to the site. After the fill material was graded
to set the slope into the hill, the gravel was placed to a depth of approximately 4 inches
along the entve 800 foot length of the road. KSLAB constructed a sediment control
basin at Quarry Town to collect any sediment that is transported down the inside of the
road.
Since all tunoffwill now be directed to the inside ofthe road, it will not be necessary to
place any fill material along the outside edge of the road.
