6.4.8 Exhibit H - Wildlife Information <br /> Wildlife Assessment <br /> Site Description <br /> Savage and Savage conducted an on-site wildlife assessment for the Ready Mixed Concrete <br /> Nix amendment project site on March 1, 2020. The Nix amendment site is comprised of <br /> approximately 307 acres within portions of Section 28 within Township 3 North,Range 67 <br /> West of the 6th Prime Meridian, Weld County, Colorado. The center of the project site is <br /> located at 40.196699'latitude and -104.893068'longitude. The property is located west <br /> of Platteville between Weld County Roads 19 and 17, immediately south of Colorado State <br /> Highway 66. The property is accessed from Weld County Road 19. <br /> Weather during our site investigation was cool,and overcast with a temperature in the mid- <br /> 40's (°F). The topography of the site is dominated by the primary alluvial terrace of the St. <br /> Vrain River. The elevation of the project area averages 4805 feet and slopes gently to the <br /> northwest toward the St. Vrain River. <br /> Topography and Geomorphic Features <br /> The Nix amendment site is located on the primary alluvial terrace of the St. Vrain River, <br /> approximately 2300 feet east-southeast of the current river channel. The topography of the <br /> property is largely flat and dominated by flood irrigated agricultural fields and associated <br /> irrigation canals and ditches. <br /> Hydrology <br /> The most significant regional hydrologic feature is the St. Vrain River to the northwest of <br /> the site. The Seep Drainage Ditch flows from south to north along west boundary of the <br /> site. A number of irrigation lateral ditches and several tailwater drainage ditches distribute <br /> irrigation water and drain the agricultural fields within the Nix amendment site as well as <br /> agricultural fields to the south and east. Tailwater eventually exits the site under Colorado <br /> Highway 66 and drains to the St. Vrain River. <br /> Soils <br /> The soils that dominate the site are formed from alluvium and consist of loams, clays, and <br /> sands (USDA, 1981). <br /> Vegetation <br /> Vegetation of the project site can be divided into native and agricultural communities. <br /> Native vegetation is restricted to the tailwater ditches that adjoin the agricultural fields. <br /> This vegetation community contains stands of cattail (Typha latifolia), reed canarygrass <br /> (Phalaris arundinacea), inland saltgrass (Distichlis spicata), rushes (Juncus sp.), and <br /> Exhibit H Page 1 <br /> Page 26 of 126 <br />
