6.4.8 Exhibit H - Wildlife Information <br />Wildlife Assessment - Arends, Reinoehl, and Archuleta Site <br />Site Description <br />Savage and Savage conducted a wildlife assessment for Ready Mixed -Concrete <br />Company's Arends, Reinoehl, and Archuleta site on August 21 2007. The site is located <br />within portions of Sections 13, 14, 23, and 24, Township 1 South, Range 67 of the 6,' <br />Prime Meridian, Adams County, Colorado. The property is bounded on the north by the <br />Boral Brighton Quarry, east by Brighton Road, south by a fence line and pond, and west <br />by a fence line and unimproved road. <br />The weather during the site investigation was dry and warm with temperatures in the <br />80's. Elevation of the site ranges from 4981 to 5009 feet and the property slopes gently <br />west towards the South Platte River. The current channel of the South Platte River flows <br />approximately 1500 feet west of the site. The terrace slope between the primary and <br />secondary alluvial terraces trends southwest-northeast through the project site. <br />According to the Soil Survey of Adams County, Colorado (1974), three different soil <br />map units are located on the site. The map units are in bands trending southwest to <br />northeast that parallel the South Platte River channel. The soil units include Nunn loam <br />(0 to 1% slopes and 1 to 3% slopes), Dacono loam (0 to 1% slopes), and terrace <br />escarpments. <br />The vegetation communities investigated include a meadow vegetation community on the <br />Reinoehl parcel and a wet meadow vegetation community and fringe vegetation along a <br />tailwater irrigation ditch on the Arends parcel. <br />The meadow vegetation community located in the southwest corner of the Reinoehl <br />property is dominated by herbaceous vegetation with no tree or shrub layers. Wheatgrass <br />(Agropyron sp.) is the dominant species, with small inclusions of cattail (Typha latifolia), <br />coyote willow (Salix exigua), spike rush (Eleocharis palustris), and blowoutgrass <br />(Redfieldia flexuosa). Plant species surrounding this wet area consist of predominantly <br />upland ruderal species. <br />The wet meadow vegetation community on the Arends site includes meadow foxtail <br />(Hordeum jubatum), spike rush, and smartweed (Polygonum lapathifolium). Ruderal <br />vegetation in the wet meadow includes prickly lettuce (Lactuca senlola), bindweed <br />(Convolvulus arvensis), lambsquarters (Chenopodium album), plantain (Plantago major), <br />Canada thistle (Cirsium arvense), and red clover (Trifolium pratense). The vegetation <br />community along the waters edge of the tailwater ditch includes meadow foxtail, spike <br />rush, knotweed (Polygonum ramosissimum), inland saltgrass (Distichlis spicata), three- <br />square (Scirpus americanus). Neither of these vegetation communities contains a <br />significant tree or shrub component.
