Rifle Gravel Pit#1 April 2022 <br /> 4.1 List of Permanent Structures <br /> Figure 3, Exhibit C1 depicts the permanent man-made structures contained on and within <br /> 200-feet of the Affected Lands. Table 1 lists these structures as well. SGM conducted a <br /> utility field investigation on November 21, 2020, that informed this information. <br /> Last Chance Ditch tailwater channel <br /> Last Chance Ditch irrigation lateral <br /> Non-potable URSA Resources water lines (supply and return) <br /> URSA Resources gas line <br /> CDOT CR 346 and culverts <br /> SGM coordinated with these utilities as required for the access road design. Copies of the <br /> signed Structures Agreements are included in Attachment B. <br /> 4.2 Adjoining Surface Landowners Map Information <br /> There are four adjoining properties with corresponding surface landowners (as depicted in <br /> Figure 3, Exhibit C1). <br /> North —Colorado River Ranch, LLC <br /> West- Rex Robinson Ranch, LLC; (includes the Swanson Colorado Trust; Ilgen, Carrol <br /> Jeanne; Rosa, Linda Jane; Robinson, James Dean) <br /> South —Colorado Department of Transportation (CDOT) <br /> East—Shidelerosa LLP <br /> This information was obtained from the Garfield County Colorado Land Explorer (Garfield <br /> County, March 2021). <br /> 4.3 Topography and Aquifer <br /> The existing surface topography is extremely flat and composed of several feet of fine- <br /> textured alluvial sediment overlying a highly permeable alluvial aquifer of coarse gravel. The <br /> coarse gravel material lies on bedrock, adjacent to the Colorado River(based upon <br /> available boring data). The only topography of note is the artificially excavated tailwater <br /> return channel of the Last Chance Ditch, with runs east to west across the property and <br /> generally bisects the property into northern and southern sections. Figure 4, Exhibit C2 <br /> depicts this feature. <br /> Figure 4, Exhibit C2 depicts information required by: <br /> 6.4.3(c) —the existing topography of the area with contour lines of sufficient detail to portray <br /> the direction and rate of slope of the affected land [112(4)(g)] <br /> 6.4.3(d) —the total area to be involved in the operation, including the area to be mined and <br /> the area of affected lands [112(4)(f)] <br /> 11 <br />
