Finish Grade: Quarry Floor, Processing Area, Waste Rock Area
Preparation of the final grade for reclamation is estimated in Exhibit L to
cost $200/acre. This cost, as adjusted for 39.95 acres of reclamation in
the revised plans, is $7,990.
Importation of Topsoil
The response to Exhibit E, above, commits to bonding for the import of
6,700 CY of topsoil material. The largest portion of the cost associated
with this import is the haul, which will be assumed to be from a source in
the urban area of the Front Range. In case of forfeiture of the bond, hiring
a trucking firm to make a 20 mile-round trip is estimated to cost $11.65 per
cubic yard, and topsoil is estimated to cost in range of $8.00 per yard in
quantities. At a unit cost of $19.65 per yard, the total cost for 6,700 CY of
topsoil import is $131,655.
