The Colorado Natural Heritage Program (CNHP) has no accounts of Federally-listed <br />plant species in the area (CNHP 2008). <br />Areas with the potential to include wetlands, such as in the riparian corridors northwest of the <br />Lafarge Brown property, were mapped during the survey. The Corps of Engineers uses three <br />indicators when making wetland determinations: vegetation, soil, and hydrology. To be considered <br />a wetland, all three indicators must be present. The areas mapped during the survey were based <br />solely on vegetation, therefore the extent of the area was maximized and includes all potential Corp <br />of Engineer wetlands. If development were to encroach on the mapped wetland areas, B&A would <br />recommend a comprehensive wetland delineation to determine the exact extent of the wetland <br />according to all three indicators. <br />Greeley 35`h Avenue Mine (M-1977-036) <br />DRMS 112 Reclamation Permit Amendment Application <br />Page J2 of J5
