<br />moderate soil erosion potentiaL with proper imPlementation of <br />soil erosion control measures, erosion from distruped areas can be <br />reduced by 90%. A wide variety of soil erosion control measures <br />will be required during construction the Miner~l county romr <br />approval, State of Colorado 40l Water Quality Ce~tification, and <br />state of Colorado Air Emissions (fugitive, dust) Permit. <br />Revegetation of disturbed areas on private land, is required as <br />part of the PUDM landscaping provisions. <br /> <br />A small portion of eroded soil however, will l1>e delivered to <br />stream channels and carried dCMllstream as sedimElnt. Table IV-2 <br />summarizes the combined impacts of soil disturbanob and subsequent <br />sedimentation for each alternative. Table IV-5 s~ows the average <br />annual yield of suspended sediment from develoJtnent on private <br />land. The impacts to water quality attributable! to soil erosion <br />from private land development are discussed in the "water quality" <br />section later in this chapter. <br /> <br />TABLE IV-I , <br />1in".1l' rR~ VlIJ.T.F.Y P.RaJECr AIII'ERNM'IVE: roIL DJplRBl\NCE <br /> <br />! <br />ONE m THREF. <br />NlA 262 1726 <br />NlA 11,ry50 10,000 <br />N/A 1055 561 <br />~VA 904 519 <br />N/A ,563 475 <br />NlA 27.5 27.5 <br />N/A Z4.5 18.0 <br />N/A r 15 11 <br />N/A : 68 44 <br />, <br /> <br />Mountain DeveloJment <br />Total Permit Area (acres) <br />Ski capacity (skiers) <br />Skiable Terrain (acres) <br />Trail Acreage (acres) <br />Total Cleared for Trails (acres) <br />Total Cleared for Roads (acres) <br />Total Cleared for Lift Lines (acres) <br />Number of Lifts <br />Number of Trails <br /> <br />Private Land Develo~ent <br />Total acres disturbed <br /> <br />N/A - Not Applicable <br /> <br />702 <br /> <br />702 <br /> <br />702 <br /> <br />TABLE IV-2 <br />mMBINED JMPACI'S OF roIL DI9l'lJRBAH:E ON !':RnTMmiPl'ATION <br />IN WESl' POI<< l\l<.'D FA-'\']' FORK FOR ~.1'Y'I'F.Il ~\L'l'ERNl'lrIVES <br />I <br />I <br />ALTEiRNM'IVE <br />SEDlMENI'ATION (TonalYr) ONE'Ml 'IHREE <br />(Includes U.S. 160 relocation) 131+244 +228 <br /> <br />b.
