tT IRIS <br />MITIGATION AND DESIGN, INC. <br />Environmental Consulting <br />Phase 1 Mitigation to be Completed after Phase 3 <br />IRIS MITIGATION AND DESIGN, INC. <br />2022 Arapahoe Street <br />Golden, Colorado 80401 <br />Phone: 720 -272 -1985 <br />bleisure@irismitigation.com <br />Of the remaining 0.79 acre of mitigation to be completed at the end of Phase 1 construction <br />activities, there will be 0.07 acre of created riparian habitat including three mitigation areas <br />which will be seeded and mulched and planted with 120 riparian shrubs as originally permitted <br />in the 2011 BA (see Table 1). The remaining temporarily impacted riparian area will include <br />0.09 acre of restored riparian area which will be seeded, mulched, and planted with 150 willow <br />stakes and 20 riparian trees. This area is located directly upstream of the cut -off wall. <br />Of the 1.48 acres of required Phase 1 mitigation, 0.69 acre will be mitigated for at the end of <br />Phase 3 site clean -up activities. The reason for the delay in mitigation is that Ralston Creek will <br />be further impacted during Phase 3 activities. We do not want to plant trees and shrubs <br />downstream of the cut -off wall in a location which may be impacted during the Phase 3 clean -up <br />process. Once the Phase 3 clean -up is complete, there will be ample space along Ralston <br />Creek and associated uplands for both riparian and upland area creation, restoration, and <br />enhancement. In addition, there will be ample space for necessary upland and riparian tree and <br />shrub plantings following Phase 3 clean -up activities. For a complete description of Phase 1 <br />mitigation activities to follow Phase 3 clean -up activities, please see Table 2. This mitigation will <br />be completed in conjunction with any additional Phase 3 mitigation needs. <br />2012 Phase 1 Actual Area Tree and Shrub Impact <br />The 2012 actual area impact due to Phase 1 construction activities to trees and shrubs was less <br />than what was originally permitted due to the decrease in area that was impacted during Phase <br />Schwartzwalder Mine Actual Area Impact Page 6 <br />January 2013 <br />
