<br />APPROXIMATE PROFILE OF EXISTING ROAD SURFACE
<br />Scale V= 200'
<br />Construction Notes:
<br />This road has been designed to meet the applicable portions of CDRMS Rule
<br />4.03.2 for Access Roads. It is specifically designed to meet the minimum
<br />design requirements while minimizing additional disturbed area and
<br />preventing environmental damage.
<br />1 Use of road is for routine environmental monitoring and occasional pond maintenance.
<br />Typical road use would consist of one trip per week by a light use vehicle
<br />using one way travel and low speed.
<br />2 Horizontal alignment will exactly follow existing two track road alignment and is
<br />consistent with existing natural topography.
<br />3 Overall grade of the existing road is approximately 6%
<br />4 Access is controlled at all times by a locked gate.
<br />5 One 18" culvert is to be installed at Sta. 39 +90 that will provide drainage under the
<br />road for flows from the unnamed drainage.
<br />6 No topsoil will be removed prior to surfacing with gravel.
<br />7 Existing road will be hard bladed to remove all vegetation and rutting and to provide
<br />a level surface across roadway.
<br />8 Maximum cut and fill depths shall be less than 2 feet.
<br />9 The completed ditch shall be broadcast seeded with the specified mixture
<br />upon completion of the roadway.
<br />10 Following blading, a minimum 4 inch thickness of clean, minus 2 inch gravel
<br />from a commercially available source shall be placed and compacted across the
<br />12 foot wide travelway. The field engineer may modify this specification to
<br />include crushed rock from the mine site provided this material meets other
<br />requirements. The road shall be crowned such that the minimum depth of
<br />gravel along the centerline is 6 inches. Approximate quantity of gravel
<br />needed is 1000 cubic yards.
<br />11 A triangular V -ditch approximately 18 inches in depth shall be cut on the uphill
<br />(Eastern) side of the completed roadway.
<br />12 No vehicular traffic allowed beyond the construction limits identified above.
<br />13 Upon completion of construction, a report shall be provided by a professional
<br />engineer certifying that the construction has been completed according to plan.
<br />14 The land owner has requested that this road remain following mining activities and
<br />will not be reclaimed.
