IRIS <br />MITIGATION AND DESIGN, INC. <br />Environmental Consulting <br />IRIS MITIGATION AND DESIGN, INC. <br />2022 Arapahoe Street <br />Golden, Colorado 80401 <br />Phone: 720 - 272 -1985 <br />bleisure @irismitigation.com <br />approximately 0.59 acre of upland located directly south of and adjacent to the installed cut -off <br />wall was restored through the removal of rocks and debris and through the addition of <br />approximately 6 inches of imported topsoil (see enclosed 2012 Progress Report Photo Log). All <br />mitigation areas were then seeded with either the upland, transitional or wetland seed mixes as <br />detailed in the IRIS 2011 Biological Assessment and hydro - mulched in July 2012. Seeding and <br />hydro - mulching activities were completed at all seeded areas to stabilize the soil following <br />Phase 1 construction activities. <br />Trees and shrubs were not installed in any of the created, restored, or enhanced mitigation <br />areas in the summer of 2012 because it was an especially dry summer and the trees and <br />shrubs might not have survived. The mitigation sites located on the north side of the creek <br />(approximately 0.16 acre total) were trampled by several cattle which illegally accessed the site <br />in late August/early September 2012. The 0.59 acre restored upland area located just south of <br />the cut -off wall was not trampled. Due to this trampling and the hot summer conditions, the 0.16 <br />acre mitigation areas were re- seeded and stabilized with erosion control blanket in mid - <br />September 2012 (see enclosed Photo Log). In addition, one disturbed riparian area <br />(approximately 500 square feet) adjacent to the discharge point of the 18 -inch pipeline was <br />prepped, augmented with imported topsoil, and seeded and blanketed in mid - September 2012. <br />This approximately 500 square foot area was temporarily disturbed during the 18 -inch pipeline <br />stabilization activities in August 2012 and was therefore revegetated and stabilized during the <br />same time as the trampled mitigation areas in September 2012. <br />Schwartzwalder Mine Actual Area Impact Progress Report Page 2 <br />January 2013 <br />
