COOLEY RESERVOIR AND FULTON WILDLIFE AREA PIT
EXHIBIT D -MINING PLAN
The proposed plan mining involves property on both sides of the S. Platte River, south of 104' ~
Avenue. Most of the property on both sides of the S. Platte River is within the floodplain of the river,
and much is also within the floodway of the S. Platte River, but no mining is proposed within the
encompassed by the existing high banks on each side oft e river.
The only disturbance proposed within this area would be by Adams County for trail construction, „ y~yr~~
construction of the support structures for a conveyor system that will span the River, and for ~ 51'; ,r/~
whatever channel improvements UD&FCD and CAMAS agree are reasonable and necessary to mine ~,~,,,
within 400' of the low flow S. Platte River channel. In the event agreement is not reached with ~"~d~d'"'
UD&FCD on required improvements within 400' of the low flow channel of the S. Platte River, then ~/ sy ~,
mining will not be undertaken within this 400' on each side of the S. Platte River. ~"~
All mining within the floodplain will require approval from the Urban Drainage and Flood Control I
District (UD&FCD) and a Floodplain Use Permit from Adams County to require all topsoil and
overburden berms be oriented in a southwest to northeast alignment parallel to the river so as not
to impede water flow in the event offlooding. Concurrent with this application, application will also
be made to Adams County for local government approvals. A formal Wetlands Inventory and a f
Wetland Mitigation Plan to remove and replace the probablejurisdictional wetlands on the site is also ~~
being prepared.
~~
Mining will include the following elements, not necessarily in the order listed. Some activities,
particularly those at the beginning of the operation, will occur concurcently:
1. Repair existing fencing and new fencing installation.
2. Topsoil and overburden excavation and stockpiling.
3. Conveyor crossing of the S. Platte River to Parcel C, and temporary conveyors as needed.
