Reclamation plan and map
a. Reclamation of this affected land has been planned and imple-
mented to provide the amenities for land use in the ~`orm of a
site development project. Feasible land use, in accordance
with the designated C-2 Zoning, motivated site development
planning and acquisition of this property. The currant re-
clamation proceedures are in essence the activation of the
chosen land development and use plans.
Although the total acreage in this parcel of land is approxi-
mately 200 acres, the plans provide for over one-third of the
area to be undisturbed. 125 acres will be subjected to some
degree of reshaping, leaving over 70 acres which will. be undi-
sturbed, which will provide part of the open space planned for
in the development. 117 acres of the 125 acres will eventually
be affected by the mining operation, but only 85 acres will be
involved to any extent by the rock extraction processes. This
117 acres is that portion of the property involved in the re-
clamation plan, and this is subdivided into approximately 7
acres devoted for the terraces on the highwalls, 5 acres for
the backslopes on the highwalls, 5'~ acres for backslopes other
than the highwalls, 1~ acres for reconstruction of Jackson
Gulch, and the balance, 98 acres, for commercial development,
which includes, building sites, parking, roads, walks, and
open space.
b. The reclamation plan relates directly to the mining operation
and will be achieved coincidentally with the mining operation.
Initial studies of the shape of this property indicated that
substantial reshaping of the terrain would be required to pro-
vide suitable building sites and develop acceptable land use.
Reshaping of part of the land will involve only the normal pro-
ceedures of cut and fill of existing soils. The reshaping of
those areas underlayed by the crystalline rock formation re-
quires the reduction of the surface to accessible levels by
quarry mining. This entire mining operation was instigated and
specifically planned for the predetermined transformation of
the natural terrain, which is essentially the reclamation plan
that will develop economically feasible land use. Re3uction
of the surface, by the orderly extraction of the Comm=_rcial
aggregates, has established interim productive use of the land
for the duration of the mining operation and subsequeZtly will
provide for it's reclamation.
In conjunction with the extraction process the featur•=s of the
highwalls will be established. Each backslope of the highwalls
will be stabilized by the removal of any loose or unsecure mate-
rials, which may be subject to errosion, in accordance with the
requirements of the Colorado Bureau of Mines. There .is pre-
sently conclusive evidence that the highwalls created by the
current mining operation are inherently stable and resistant to
prolonged efforts of errosion. The location of the highwall was
specifically selected in order to provide for a harmonious con-
fluence of the highwall with the undisturbed land. A.Lso terraces
will be established in the face of the highwall during the course
of the mining operation. These terraces will be spaced at in-
tervals not exceeding 50 feet in elevation and so des:~gned as
to preclude the formation of extended and continuous ]~orizontal
lines across the face of the highwalls. Each terrace will be
at least 20 feet in width and will slope from the outer edge
to the highwall to further resist errosion and contro:L water
runoff. It is intended that the highwall have the apI>earence
of exposed rock faces and ledges. Intermittent revegetation
of these terraces is planned. Stockpiles of topsoil tore being
accumulated for this purpose. A selection of woody p=_ants and
grasses recommended by the Soil Conservation Service will be
used. Final terracing will begin at the highest elevation and
progress to the lower elevations as the rock is extra<;ted at
each level. Dressing of the highwall above each terrace will
be completed the terrace shaped and graded, and revegetation
of the terrace surface be instigated.
