RAG TMCC Fish Creek 2003: Wetland Delineation Report <br />• Project B -Intake Shaft and Access Road <br />Location/Site Context <br />The proposed intake shaft and access road are located in Section 17 of Township 5 North, <br />Range 86 West, in Routt County Colorado (Map 3). The proposed shaft pad is 280 by <br />280 feet surrounded by a 500-foot wide disturbance zone. The access road is <br />approximately 2,930 lineal feet from start to end point. A 100-foot wide corridor was <br />surveyed along the entire length of the proposed access road corridor at a width of 50 feet <br />perpendicular from each side of the centerline. The access road begins at an existing vent <br />shaft located neaz the edge of the Fish Creek flood plain. The proposed access road <br />proceeds northwest, terminating at the proposed intake shaft location. The only wetlands <br />identified within the project azea aze located in the vicinity of the proposed shaft pad <br />(Photo 5). The access road is located entirely within upland grass and shrub dominated <br />plant communities (Photo 6). <br />Wetland Description and Justification <br />Wetlands are confined to azeas within an intermittent drainage indicated by a dashed blue <br />line on the USGS topographic map of the azea. The drainage shows considerable <br />variation within the survey area. The upper reach has poorly defined banks but there is <br />sufficient scouring to prevent persistent vegetation communities from establishing. <br />• Midway along the surveyed reach the channel is cut deeply and the banks aze well <br />defined. The bottom and banks of the channel support hydrophytic vegetation in areas <br />where groundwater seeps aze evident. <br />Table 1: Plant Species List <br />• <br /> <br /> <br />Scientific Name <br /> <br />Common Name Indicator <br />Status <br />Re ion 8 <br />Achelia millifolium Yarrow FACU <br />A rostis i antes Redto FACW <br />Artemisia cans Silver Sae FAC <br />Artemisia tridentata Bi Sae FACU <br />Bromus inermis Smooth Brome UPL <br />Carex nebrascensis Nebraska Sed a OBL <br />Carex utriculata Beaked Sed a OBL <br />Dasi hors floribunda Shrubb Cin uefoil FACW <br />Hordeum 'ubatum Fox Tail Barle FAC <br />Juncus balticus Baltic Rush FACW <br />Nasturtium ofricionale Water Cress OBL <br />Pasco rum smithii Western Wheat rass FACU <br />Phalaris arundinacea Reed Cana Grass OBL <br />Phleum ratense Timoth FACU <br />Habitat Management, Inc. 3 01/06/03 <br />
