Baseline Technical Report <br /> ARCADIS Report for Soils and Biological <br /> Resources, MLE2 Project Area <br /> conducted by the U.S. Department of Agriculture (USDA) Natural Resources <br /> Conservation Service (NRCS) (Soil Conservation Service prior to 1994) in 1993 and <br /> 1995. At that time, three dominant soil units were identified within the Cresson <br /> Project area: <br /> • Grenadier-like-Unnamed very gravelly loam complex(HL); <br /> • Quander-Varden complex(PF); and <br /> • Rogert very gravelly sandy loam. <br /> In 1996, CC&V conducted a modified Order II soil survey to map a portion of the <br /> Cresson Project area to the series level in support of the Amendment No. 7 project <br /> (JBR 1997). Approximately 60 soil pits were used to determine soil characteristics in <br /> the field including the soil depth, types of horizons, parent material, structure, texture, <br /> color, pores, stoniness, roots, and other special characteristics. The mapped soils <br /> were identified to the soil series level where possible, using named soil associations <br /> identified by the NRCS. <br /> NRCS updated the soils mapping for parts of Teller and Park Counties, including the <br /> survey area. Information on NRCS soil units in the survey area is available via the <br /> Web Soil Survey website (SSS 2011), which was developed by the NRCS to provide <br /> access to the most current soil data. A review of the most current soil spatial (Version <br /> 4, May 19, 2008) and tabular data (Version 4, March 7, 2008), indicated <br /> discrepancies between previous JBR Environmental Consultants (JBR), Greystone <br /> Environmental Consultants (Greystone), and ARCADIS soil mapping and current <br /> NRCS mapping. <br /> 1.2.1.2 Vegetation Resources <br /> Existing baseline information on vegetation resources in the survey area was <br /> collected, compiled, and reviewed for completeness and accuracy. The existing <br /> baseline information was primarily based on past field surveys and vegetation <br /> mapping efforts completed by JBR in 1997 in support of Amendment No. 7, by <br /> Greystone in 1999 in support of Amendment No.8, and by ARCADIS in 2007 in <br /> support of Amendment No. 9. <br /> 1.2.1.3 Wildlife Resources <br /> ARCADIS compiled baseline information on wildlife resources by reviewing data from <br /> CC&V's files (CC&V 1992, 1993, 1998); wildlife inventories performed by Colorado <br /> Division of Wildlife (CDOW) in 1997; and wildlife inventories performed by JBR in <br /> CCV Baseline Soils Biology Resource Report(11-17-11).doc 3 <br />
