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 />
