portion of the Thompson River Ranch residential subdivision also borders the southern boundary of the Property. Agricultural land is adjacent to the Property's eastern border. B. Project Description Coulson proposes sand and gravel mining from two separate cells on the Property. The western cell will be approximately 35 acres (the "West Cell") and the eastern cell will be approximately 15 acres (the "East Cell", together with the West Cell, collectively, the "Cells"), as depicted on Exhibit A-1. The Cells are separated by a 100-foot wide gas pipeline easement. The West Cell will have a 266-foot setback from the western property line and a 363-foot setback from the southern property line. There is a 300-foot buffer of native vegetation between the northern edge of the Project and the Big Thompson River to avoid encroachment within the floodway that runs along the northern border of the Property and to preserve wildlife habitat. Coulson anticipates the Project will last approximately five (5) to seven (7) years including reclamation of the mine, depending on market conditions. Mining will commence in the southwest corner of the West Cell and progress northward in 5-acre sections. Coulson will repeat this same pattern of extraction in the East Cell. The minable sand and gravel is located beneath a layer of approximately 6-8 feet of topsoil, silt, clay and other material (the "Overburden"). As the Overburden is excavated, Coulson will use the Overburden to build 10-foot earthen berms along the western and southern portions of the Property to screen mining operations from the adjacent residential uses. A conveyor belt will transport the sand and gravel produced from each Cell across the Property to the Kirtright Property. Specifically, the conveyor belt will run along the northern edge of each Cell, ending at the Kirtright Property where Coulson will then process the sand and gravel and load it onto trucks for transport off-site. Full mining operations, including mining the Cells,transporting materials to the Kirtright Property, processing the sand and gravel and hauling out finished products will occur Monday through Friday from 7:00 A.M. to 5:00 P.M. On Saturdays, Coulson will haul processed materials from the Kirtright Property from 7:00 A.M. to 5:00 P.M.; however, there will be no mining or materials processing on Saturdays. On Sundays, there will be no activity on the Property or the Kirtright Property of any kind. The final step of the Project is mine reclamation. Once the sand and gravel mining is complete, Coulson will reclaim the Property into an aesthetically appealing parcel of land. One option Coulson is considering for the reclamation of the Project is the conversion of each Cell into a clay lined lake, which, as necessary, will be filled with lawfully decreed surface water. E Specifically, the West Cell could be converted into a 28.4-acre lake and the East Cell into a 10.5- 2 42
