Scope <br /> This report presents the results of our Geotechnical Investigation for the proposed sand <br /> mine in Kersey, Colorado (Figure 1). The purpose of the investigation was to explore the <br /> subsurface conditions, and provide material information and testing results. The scope was <br /> described in a Service Agreement(No. FC-23-0426 CM-1)dated April 22, 2024. Evaluation of the <br /> property for the presence of potentially hazardous materials was not included in our work scope. <br /> The report was prepared from data developed during field exploration, and field and <br /> laboratory testing. The report includes a description of subsurface conditions found in our <br /> exploratory borings. The report was prepared for the exclusive use of TRC Companies and your <br /> team. Our findings are summarized in the following paragraphs. <br /> Summary Of Conclusions <br /> 1. Strata encountered in our borings generally consisted of clayey sands and sandy <br /> clays over sandstone and claystone bedrock. Primarily sandstone bedrock was <br /> encountered between approximately 8 and 24 feet and extended to the maximum <br /> depths explored. <br /> 2. Groundwater was measured at an approximate depth of 24 feet in one boring <br /> during drilling. Groundwater levels may fluctuate seasonally and rise in response <br /> to precipitation, irrigation and changes in land-use. <br /> Site Conditions <br /> The site is located east of Weld County Road 61 and south of Weld County Road 64 near <br /> Kersey, Colorado. The site is generally in a plains area and is primarily vegetated with grasses <br /> and weeds. At the time of our exploration the site was undeveloped with utilities and dirt roads. <br /> The project site is generally hilly. No water features or rock outcrops were noted onsite. Oil <br /> industry infrastructure and access roads were noted onsite. <br /> Previous Investigation <br /> CTL Thompson performed a Preliminary Geotechnical Investigation on a northern section <br /> of the site (Project No. FC11079.000-115), dated April 5, 2024. The previous investigation was <br /> reviewed in preparation for this report. <br /> TRC COMPANIES <br /> KERSEY SAND MINE 1 <br /> CTU T PROJECT NO.FC11079.001-125 <br />
