In situ- Upon arrival at the site a search of drainage pattems and possible atypical conditions was made for <br />the region surcounding the site. Watershed pattems that influenced the Flow of possible wetland features <br />were noted, as well as observed current climatic conditions (No weather station data available for the <br />immediate area), past climatic conditions, and land use pattems that may affect the hydrologic regime of <br />the area. The Colorado Division of Water Resources w'as also consulted for annual flow rates of the <br />Florida River. Subsequently, eight (8) wetland areas were identified within the property (Appendix A; <br />Figures 2 & 3). Three (3) of these wetland areas were seepage wetlands along the eastern terrace slope, <br />four (4) were associated with riverine headwater and backwater flooding areas, and one (I) was associated <br />with the creek atop of the west terrace ridgeline. Forrnal delineation procedures were employed to <br />determine the nature of these areas. <br />3.1.1 On site; 18 & 22, August 2005 <br />During the wetland identification, modification of vegetation parameters was not required. Soil pits were <br />dug to a depth of at least 20", where possible, to test for the possibility of samtated soil conditions below <br />the average rooting depth. ]nterprefation of saturation and water table depths were made upon using best <br />professional judgments considering the decreased probabilities of meeting wetland parameters during the <br />current low Flows in the Florida River <br />Separate "test pits" were dug in suspect areas to gain insight as to the actual tapering fringe from wetland to <br />upland. These pits were dug at distant areas surrounding the site to deternine the nature and differences in <br />surrounding hydrological drivers. <br />A United States Department of Interior, Fish and Wildlife Service "National List of Plant Species <br />that occur in Wetlands List" was used to obtain vegetation designations. <br />3.2 DELINEATION RESULTS <br />I[ is important to note that the surface water features of the area were assessed for relative function within <br />[he single geomorphic landscape of an alluvial riverine system influenced by numerous geologic functions <br />including outwash evidence from glaciations. Moreover, aR are functioning in a palustdne environment. <br />Each of the wetlands was investigated and boundaries were delineated by generating sample points <br />assumed to be clearly within the wetlands and within close proximity to the tapering fringe of their <br />assumed boundaries. The plot data results were used to interpret qualitative indicators (defined topography, <br />apparent vegetation dominance) around the site. <br />3.2.1 Wetland Descriptions/Findings <br />Functions and values of wetlands in the project area were assessed utilizing the United States Fish and <br />Wildlife Service Cowardin classification system as well as Brinson's (1993) "A hydrogeomorphic <br />classification for wetlands" technical report. Specific reference to other similar hydrogeoligical areas was <br />gathered from. "A guidebook for application of hydrogeomorphic assessments to riverine wetlands" <br />(Brinson, e[. al. 1995), and "A Regional Guidebook for Applying the Hydrogeomorphic Approach to <br />Assessing Wetland Functions of Riverine Floodplains in the Northern Rocky Mountains" (Hauer, F. R., et <br />al. 2002). <br />3.2.1.1 Terrace Slope Seep Wetlands (Isolated) <br />(1)Semi-Permanently Flooded, Emergent Palustrine Wetland <br />These areas are apparently influenced from extensive irrigation resources up-gradient along the mildly <br />rolling pasture and agricultural fields around the Oxford region, resulting in groundwater recharge later into <br />the year than would be typically witnessed in its absence. <br />Three of these wetlands exist across the proposed project property and into properties impacted by tfie <br />proposed access road. They are all very similar in natre and are each apparent mid-slope of the eastern <br />s.ms vrs~,«y. r .;A~,ei c~~~s~ii~s. rcc <br />
