B. Site Topography(G.1.b) <br /> The site location and topography are discussed in detail in the attached Fox report submitted as part of <br /> the original DMG permitting and those details are not repeated herein. Additional comments about site <br /> topography for the present rezoning effort include the following: <br /> 1. Pre-mining slopes at the site were closer to approximately 2:1 than 2.5:1 as reported in the <br /> Fox report. <br /> 2. The cut slope along the west side of U.S. 285 across the highway from the quarry is <br /> approximately 1:1 overall, and steeper in the lower cut face. <br /> 3. Historic mined and reclaimed slopes by others at the site are as steep as 1:2 and appear to <br /> be generally stable. <br /> A site topographic map was included in the original DMG permit application. This map is included as <br /> Attachment A to this report. The Geologic Map prepared for this report and included in Attachment B <br /> also shows the pre-mining topography. In addition, Elk Creek has developed a very detailed site <br /> topographic map prepared by Falcon Surveying, Inc. based on a June 2, 2004 field survey. A copy of the <br /> new detailed topographic map showing existing conditions (1 in =40 ft; 1 ft contour interval) is provided <br /> elsewhere in the rezoning submittal. <br /> C. Test Borings or Core Samples (G.1.c.) <br /> No test borings were performed and no core samples were obtained as part of original site permitting <br /> efforts. Since that time quarry development has occurred and there are ample bedrock exposures at <br /> the site to preclude the need for test drilling to identify site lithologies. Topsoil and overburden <br /> thickness are negligible,varying from less than a foot to approximately 3 ft thick. There is an upper <br /> weathered bedrock zone in which moderately severely weathered to completely weathered bedrock <br /> extends approximately 15 to 20 ft into the rock mass. Bedrock exposures at the site have been mapped <br /> for geologic structure and these data are included in the slope stability section below. <br /> D. Sites of Special Geologic Interest(G.1.d.) <br /> There are no known or suspected sites of special geologic interest(e.g.,fossil beds)at this site. No <br /> features of special geologic interest are anticipated to occur because the site is located within an <br /> extensive outcrop of Precambrian metamorphic rocks that are prevalent in the Front Range from west <br /> of Colorado Springs north to west of Fort Collins. <br />
