Cripple Creek 8 Victor Gold Mining Company Traffic Study <br />• TRIP GENERATION <br />The increased operations and production proposed under Amendment No. 8 will generate <br />additional vehicle traffic to and from the mine. This section estimates the increases in the <br />number of trips that can be expected from the Amendment No. 8 expansion and quantifies <br />the existing and proposed truck traffic, from mine expansion and from mobilization activities <br />associated with construction of the expanded operations. <br />Employee Commuting <br />CCBV is located close to the communities of Cripple Creek and Victor. While a significant <br />percentage of employees live in these two communities, other employees live away and <br />commute longer distances to work. The expansion of mining activities is expected to result <br />with the need to hire approximately 59 additional regular employees. Since the mine <br />operates 24 hours a day, 7 days a week, the additional employees will not all be on the site <br />at the same time, but will be spread among the different shifts working in various locations. <br />To estimate the vehicle trips generated from the expected increase in employment, we first <br />consulted the Institute of Transportation Engineers (ITE)'Trip Generation" text. Although <br />data for traffic characteristics of mining operations is not explicitly contained in the reference, <br />several similar land uses were documented. ITE Land Use #120 (General Heavy Industrial) <br />and Land Use #140 (Manufacturing) were both consulted to gain an understanding of the trip <br />generation potential from mining employment. <br />General Heavy Industrial (Land Use Code #120) uses are generally high concentrations of <br />employment at a single location. Average vehicle occupancy for commuting trips to these <br />• land uses is about 1.30 persons/auto. The average trip rate for this land use is 0.82 trips per <br />employee during an average weekday. <br />Manufacturing (Land Use Code #140) represents land area where primary activity is the <br />conversion of raw materials into a finished product. The facilities typically contain office <br />space, warehouse, research and associated functions in additional to actual production <br />facilities. The average trip rate for this land use is 2.10 trips/employee during an average <br />weekday. <br />Discussions with mine personnel indicate that most employees drive alone to work, and do <br />not leave the mine during the course of their shift. The need to travel between administrative <br />offices in Victor and the mine produces some vehicle traffic during the day, but it is estimated <br />to be an insignificant volume when compared to commuting traffic or background traffic on <br />the County Roads and Highways in the area. <br />Based on the research of available data and discussions with mine personnel, we will <br />assume that each employee drives alone and produces one (1) arrival and one (1) departure <br />trip each day. The 59 additional employees would therefor be expected to generate a <br />maximum additional 118 vehicle trip ends over the course of a 24-hour day (59 round trips). <br />New employment trips will mostly be oriented to the two primary mine employee access <br />points (Ironclad and Carlton). For purposes of this traffic impact study, new employees were <br />'assigned' to an access location based on the existing number of employees using an <br />access. This methodology results with about 32 new employees using the Ironclad entrance <br />. and about 20 using the Carlton entrance. Remaining employees are assumed to work in <br />Victor offices or elsewhere, and are not considered signfcant for purposes of traffic impacts. <br />TranSystems Corporation -March 7, 2000 Page 4 <br />
