Most of the traffic of concern is gravel haul trucks, of which there will be two types, semi -end dumps <br />of 24 tons capacity and tandem trucks of 15 tons capacity. It is expected that 60% of the tonnage will <br />be hauled by the 15 ton tandems and 40% by the semi end dumps. It is also expected that 50% of the <br />traffic will move south of Alma and 50% will move north of Alma. For all trucks moving south, the <br />south entrance will be used and the town will be avoided. For north traffic, all at- tempts will be made <br />to use the north access, but grade considerations at this entrance will force some trucks to use the south <br />entrance. <br />Using an average of 130,000 tons per year of total aggregate/asphalt or concrete hauled from the site in <br />a year, the following traffic calculations are given: <br />130,000 tons /10 months activity =13,000 tons per month. 13,000 tons/month /24 days per month = 541 <br />tons/day <br />Since 60% of tonnage will use 15 ton trucks and 40% will use 24 tons, the average is 18.6 tons. <br />Therefore, at 541 tons per day, this is 541/18.6 = 29 loads per day over 12 hours. <br />This is 2.4 loaded trucks per hour, and 2.4 empty trucks will return per hour. Other traffic such as <br />employees, sales, fuel, etc. will be estimated at 1.0 vehicles per hour, therefore the total traffic per hour <br />is expected to be 2.4 x 2 = 4.8 +1 (other traffic) = 5.8 vehicles per hour rounded to 6 vehicles per hour. <br />A maximum peak flow would be 7-8 vehicles per hour. <br />This is well within CDOT limits for requirements of accel or decel lanes from the operation, even if one <br />entrance was used. Since this traffic will be equally split between Access #6 to the north and either <br />Access #1 or Access #4 to the south, the peak hourly traffic at either entrance would be 3-4 vehicles per <br />hour. <br />8) The projected final use of the site (see reclamation plan) is a combined use of commercial, residential <br />and open space with ponds. The reclamation plan calls for much smoother surfaces, placement of topsoil <br />or substitute topsoil on all areas, seeding and tree sapling planting. The Trust also plans to work with <br />the local office of the CDOW to discuss any ways that the final site could be enhanced for wildlife. The <br />commercial portion is planned along Highway 9 (which is also shown on the existing town master plan) <br />and residential is planned for the area further east of the Highway. Wetland areas will be planned along <br />Alma Place Mine 01/15 38 <br />
