ALBERT FREI AND BONS, INC. PAGE 2
SEPTEMBER 2fi, 2006
(f) No specific engineering was done when the material was placed as
none was required buy Colorado Department of Health regulations
applicable at the time. We found that as the fill material was
placed it was compacted by the dozer and loaders used to move the
material into the excavated area. It is nearly impossible to test
for compaction on this type of fill since it contains fairly large
dense pieces of material that do not compact. In general the finer
particles of dirt, asphalt and concrete fragments filter around the
larger pieces leaving few voids so the fill is stable when done.
The "OPEN SPACE" areas shown on the PUD map were undisturbed areas
around the mined and filled area. Along the railroad tracks this area
has been vegetated. In the northeast corner contains a spring that has
served the property for many years. Originally it was used to irrigate
the farm prior to mining. A small pond was created when the area around
it was filled to keep the water from running across the property. The
water now flows along the north side of the property until it soaks back
into the ground before reaching the railroad. This spring will remain
when reclamation is complete. There will be no stormwater control
facilities left on the site when reclamation ends. However, once the
Reclamation Permit is released and full development can be completed this
site will have stormwater retention facility (s) as required.
Recycle asphalt and concrete are inter materials by definition so
there are no toxic or acid forming material on the site, nor will there
be any left on the site post-mining.
The smaller western parcel {Lot 1-Block 2) will be graded and
leveled as shown on the map. This is consistent with the PUD which
states the parcel will be used for equipment storage, truck parking and
other uses allowed on the PUD. As noted in the text on the PUD map for
that area, a screening berm will be put along the highway and landscaped
within 3 to 5 years after filling is complete. The landscaping was a
condition placed on the PUD to get it approved and has nothing to do with
the reclamation plan. We feel it is a voluntary activity that is the
landowners prerogative, The berm construction, tree planting and seeding
of the berm are over and above what is required in our reclamation plan
and we prefer to keep it this way.
I hope these responses are what you are looking for and if you have
any questions please call me at [phone] or Steve O'Brian of
