RE: File No. M-90-021 Virginia Acres, Adequacy Items
For the sake of clarity and continuity, our responses to the Adequacy Items will
be offered in the order that they have been presented to us.
MINING PLAN (Exhibit D)
1. Included, revised mining plan maps depicting "three phase" aspects.
/z Also, more topographical detail of the site regarding current conditions,
adjacent river channel, and proposed excavation.
2. 7'apsoil/Overburden
The total depth oP soils above the gravel deposit varies from il' to 4'
with an estimated average depth of 8' over the entire site. Exploration
oP the site indicates that topsoil exists to a depth that ranges from 12"
to 18" with a probable average depth of 16".
This quantity of topsoil is certainly adequate to provide a minimum of 12"
for all areas that require supplementation for reclamation. The plan to
salvage this soil for reclamation purposes is to store it in berms at
carious locations around the perimeter of the site. Our Mesa County
permit requires that an earthen berm be placed along the property boundary
of the adjacent property that is identified as being owned by Billy D and
Tracy D Kyle that is in the northeast corner of the site. This berm will
tie 800' long, 8' high, and 30' at the base, and will store 5,500 cubic
yards.
Additionally, an earthen berm will be constructed along the northern edge
cf the site for the greater part of the entire boundary. This berm will
be 850' long, 8' high, and 30' at the base, and will store 6,000 cubic
Surds .
As recommended by the Division, an earthen berm adequate to withstand the
flow of a 100-year flood will be built on the east and south sides of the
~ ,;.' site. Topsoil will be used in the upper 2' of these berms. This will
require 1,600 cubic yards. The total amount of topsoil that is to be
,.
salvaged is approximately 15,000 cubic yards.
' T'he berms that have been addressed will require 13,000 cubic yards. Of
' •~ these, 11,500 yards will be available for reclamation purposes and 1,600
~,?'' '~' yards will remain in the berm along the southern edge of the site.
Appropriate measures will be taken to stabilize these stockpiles of
~, topsoil with vegetation since they will be in place for more than one
