WORWEST ENGINEERING EVALUATION OF LTC ROAD <br /> JULY 28,2016 <br /> COR PORAT ION PAGE 9 of 10 <br /> feet to remove unnecessary curves. This road segment will be engineered and constructed following the <br /> Federal Highway Association guidelines. Thus, there will be no impacts to safety or ease of use on Little <br /> Turkey Creek Road. <br /> Conclusions <br /> The Little Turkey Creek Road structures within 200 feet of the proposed Hitch Rack Ranch Quarry include <br /> three sets of culverts and the road. The current road condition requires high clearance vehicles, and four- <br /> wheel drive is necessary during inclement weather. The road is currently subject to periodic flooding, <br /> erosion,culvert overtopping,and rock falls. The quarry has been designed with 100-foot offsets from Little <br /> Turkey Creek and Deadman Creek and a separate access road. This results in little to no impacts to Little <br /> Turkey Creek Road. There will be no increased wear and tear due to heavy loads. The quarry water <br /> management structures will not cause the risk of flooding, erosion, rock falls, or culvert failure to increase <br /> beyond current levels. <br /> Engineer Certification <br /> This engineering evaluation of Little Turkey Creek Road is complete and accurate to the best of my <br /> knowledge. <br /> 40848 <br /> .N4,E�' <br /> References <br /> Colorado Geological Survey (CGS), 2008.
