Site Description Exhibit B (cont) <br /> those areas will not be reclaimed. Approximately 0 .42 acres of <br /> the spill area in the existing permit area. <br /> In 2013 , a rock quarry was permitted on the lower end of the <br /> new permit areas as a stone mine (M-2013-068) to provide much <br /> needed quarried hard rock to repair damages to infrastructure <br /> around Lyons as a result of the September 2013 flood. This 111 <br /> Limited Impact mine started on an old area disturbed by mining <br /> sometime in the past . There was little or no soil or vegetation <br /> on the area and it was used as an equipment storage area for the <br /> landowners . The reclamation plan called for leaving a single <br /> vertical face on the north side with the floor being graded and <br /> graveled. <br /> All roads have existed since 1949 when mining begin and are <br /> maintained by Colorado Rose Red as needed. They have been in <br /> continues use since then. Review of current airphoto' s show that <br /> from the property line to HWY 36 the road services 6 houses along <br /> it' s length and is the only access the landowner has to the <br /> house, garages and ranch facility surrounding the permit area . <br /> SOILS INFORMATION <br /> All land in the permit area is solid granite . This site <br /> covers a very steep rocky hillside in southern Larimer County. <br /> Many parts are near vertical cliffs, bald rock domes or minimally <br /> vegetation cover areas that contains mostly a few evergreen trees <br /> with a sparse grass under story. The average existing slope <br /> varies from 56 degrees (lv: 1 . 5v) to 61 degrees (1h: 1 . 8v) . The <br /> original quarry area was built at the base of a rock face on the <br /> upper part of the hill . There has never been any vegetation on <br /> the old mining areas and is very limited on the rest of the site . <br /> In most cases, the fines that cover the rock, where some grass <br /> grows is a decomposed stone where pine needles have broken down <br /> creating a growth medium. <br /> Onsite investigations suggest that approximately 68 . 9% or <br /> 6 . 88 acres of the 9 . 99 acres is bare stone with scattered trees <br /> growing out of the rock. The remaining area, 3 . 11 acres, is <br /> covered with 3 to 13 inches of soil that cannot really be called <br /> 4 revised 6/7/18 <br /> �H1Il.`r awl I\L.N4.1 1 to 1111Y 1 It JIM <br />
