Description of Man Made Structure: <br />Engineering Evaluation: <br />Certified By: <br />DEN 97,636,866v1 10 -19 -11 <br />Engineering Evaluation <br />For Elizabeth A. Vaught <br />Fence <br />By Daniel Madruga, P.E. <br />CLC Associates, Inc. <br />Elizabeth A. Vaught owns a three -strand T -post wire fence which is located along the <br />eastern edge of her property, and approximately 60 feet from the western edge of the New <br />Access Road, between approximately Line Stations 20 +00 to 21 +00. <br />I present the following engineering evaluation to mitigate or avoid any potential damage <br />to the Vaught fence. I have designed the New Access Road between Line Stations 20 +00 and <br />21 +00 consistent with the Clear Zone concept specified in the American Association of State <br />Highway and Transportation Officials (AASHTO) - A Policy on Geometric Design of Highway <br />and Streets. In this Policy, the term "Clear Zone" is used to designate the unobstructed, <br />relatively flat area (less than 10% grade) provided beyond the edge of the traveled way for the <br />recovery of errant vehicles. The clear zone includes any shoulders or auxiliary lanes. For low - <br />speed rural collectors or rural local roads, a minimum clear zone width of 10 feet should be <br />provided. The distance between the New Access Road and the Vaught fence is approximately 60 <br />feet, and the grade along this distance is approximately three percent, sloping from the New <br />Access Road to Ms. Vaught's property line. In my professional opinion, Wildcat's design, <br />which meets this Policy, will create an appropriate buffer zone which will prevent any <br />substantial risk of damage to the Vaught fence as a result of activities occurring at the Wildcat <br />mining operation. <br />
