wild-rye, and mountain bottlebrush squirrel tail. The dominant observed species are sagebrush <br /> and rabbitbrush. <br /> Onsite wetlands were assessed by Lori Carpenter, PWS, SPESC of geosUAS, Inc., Reno, <br /> Nevada, in 2016 and 2017 for Aurora Water to accurately determine the Final Hallenbeck Ranch <br /> US Army Corps of Engineers (USACE)wetland determination. Citation of the study is as <br /> follows: "geosUAS, Inc., 2017. Supplemental Data to Finalize Potential Waters of the United <br /> States (WOUS)/Wetland Jurisdictional Determination for Hallenbeck Ranch, Lake County, <br /> Colorado, Leadville, Lake Coun(y, Colorado, July 2017 Leadville, Colorado, 45 pp. plus 8 <br /> Attachments." The assessment serves as comparison to a 2015 study conducted by the same <br /> hydrologists and geosUAS, Inc. Wetlands areas on site are decreased from 159.31 acres in 2015 <br /> to a current 2016 distinction of 83.13 acres through the site. Geos has determined that the <br /> potential WOUS/wetlands at the Hallenbeck Ranch are not subject to jurisdiction under Section <br /> 404 of the Clean Water Act. <br /> Wetland species discoverable in 2016 on the Box Creek Placer site include: quaking Aspen, <br /> native willows, Drummond's willow, blue joint reedgrass, Mountain willow, plane willow, <br /> Booth's willow, water sedge, beaked sedge, tufted hairgrass, Geyer's willow, Bellardi bog sedge, <br /> alpine meadow rue, shrubby cinquefoil. Upland vegetation adjacent to the wet meadows is <br /> primarily dry and includes: Kentucky bluegrass, Baltic rush, slender wheatgrass, and Wyoming <br /> sagebrush.Additional species can be found within the 2016 geosUSA, Inc. study detailed above, <br /> see Attachment 2, Table 3 therein. <br /> Box Creek Placer Mine Greg IAh icki and Associatm PIA <br /> September 2018 J-2 <br />
