C I7Y OP <br />Grand ]unction Riverside Parktivay <br />C O L O R A D O <br />EXHIBIT "C" -MINING PLAN <br />a. The proposed dates for the excavation of pit run from this borrow site are <br />December 1, 2006 to June 1, 2007. <br />b Their was no discernable growth median suitable for plants located on the east <br />side of the drainage. When the site was surveyed, the gravel soils were located at the <br />surface. There was also crushed asphalt material on the surface. In the past this site <br />had been used by the City as a solid waste transfer station and as a storage site for <br />solid waste equipment. <br />The Environmental section of the Cultural Resource Survey shown in Exhibit B <br />describes the flora found on the site to be "basically barren". There is some cheat <br />grass growing on the disturbed areas on east side of the drainage. This barren <br />condition is due to the lack of any topsoil on the site. <br />The west site of the operation was used as a dairy feed lot from 1927 to 2005. it <br />was also used as a site to store parks materials such as wood mulch. The manure that <br />was left on site rendered the upper soils unsuitable for as growth medium due to the <br />high alkalinity. The upper material was removed from the site and disposed. There are <br />no grass or shrubs growing in the west side of the site. <br />c There is no overburden on the site other than the manure contained soils on the <br />west side of the operation. The pit-run material extends to the existing surface. The <br />manure contaminated soils that were removed were 6" to 12" thick. <br />d The deposit varies from 6 to 16 feet deep on the east side and 4 to 18 feet deep <br />on the west side of the operation. The deposit varies in depth due to the clay stone <br />underlying the gravel materials. <br />e The mining operation will be done in two stages. The east side of the operation <br />will be the first stage. The gravel materials will be excavated from a face established <br />running approximately north east to south west. A 330 Cat excavator will be used to <br />work an 8 foot exposed face and load trucks that will haul the material to the fill located <br />approximately 1/2 mile north of the operation. (See attached Grading Plan). <br />The west side wnsists of a long, narrow ridge that will be lowered and sloped from west <br />to east (See attached Grading Plan). This area will be excavated in 8 foot lifts as <br />described above. The 3:1 slope along the north side of the property will be established <br />2529 HIGH COUNTRY COURT,GRANDJUNCTION,CO 81501 P[970]2564177 F[970]2564014 rlver5idepkwvCa~eiCitv.orc <br />
