Cripple Creek & Victor Gold Mining Company MLE Traffic Impact Study <br />The MLE project will add a relatively small amount of traffic to area roadways due to the <br />Phase 5 VLF construction. As mentioned previously, this traffic will only be temporary <br />traffic, however, and will not be a part of the normal everyday traffic once that facility is <br />built. <br />Future Traffic Volumes and Patterns <br />Future peak hour traffic (Year 2015 and Year 2024) will include the increases in mine- <br />related traffic (from its current volume to the potential maximum volume) and an <br />increase in non-mine-related traffic or background traffic. <br />Background traffic is the traffic that would be on the highway without consideration of <br />the mine traffic. In order to project future background traffic, Interstate Engineering <br />obtained historic traffic volumes from Teller County to determine a historic growth rate <br />to use to project future traffic. The historic volumes don't show any sort of a growth <br />trend with which to project future background traffic. A plot of the data reveals that the <br />volumes have been up and down through the years. In previous studies, background <br />traffic (or non-mine-related traffic) has been projected into the future using a two percent <br />per year growth rate. For the purposes of this study, non mine-related traffic (or <br />background traffic) was projected to grow at 2 percent per year. This rate is a standard <br />rate that is used in normal growth areas in the absence of historic growth rates. <br />The other part of futureo traffic growth is the increase in mine-related traffic from the <br />current truck delivery volumes (34 truck deliveries per day, based on the traffic counts) to <br />the maximum potential (50 truck deliveries per day, estimated maximum). Assuming <br />that each truck delivery is one trip into the mine and one trip out of the mine, this will <br />result in an additiona132 truck trips per day. <br />Figure 5 shows future total traffic volumes and delivery patterns for diesel, gasoline, and <br />lime deliveries for Year 2015 traffic given the changes due to the MLE. These volumes <br />take into account the future background traffic; the maximum potential truck deliveries <br />(described previously); the change in delivery route of the diesel, gasoline, and lime <br />delivery trucks; and the physical impacts of the mine on CR 82 and CR 83. <br /> <br />Interstate Engineering, Inc. 11 April, 2008 <br />
