'i <br /> <br />should not experience loss of function, but will in fact, <br />function as filters to detain silt and seeliment prior to <br />entering surfoce or sLu:>surface woters. The small, eph611eral <br />drainage char:nels that emerge from the wetland area ll'ay <br />become muddy and turbid during construction. However, tl1ese <br />channels will ultimately filter through wetlands prior to <br />entering the West Fork of the San Juan Fiver. Runoff fram <br />highway pavement and minor erosion of tl1e rood base Jllay <br />continue over the long-term; however, the downslope wetlands <br />will trap and filter sediment and highway runoff. Since the <br />road construction will consist of fill rJacement rather than <br />cut and dredge, subsurface flows should not be altered. <br />~~intenance of existing surface and subsurface fl~is by <br />culverting will insure that the wetland area hydrology does <br />not change. <br /> <br />The entire developnent is obovE< the ~!est Fork and Wolf Creek <br />100 year floodplain, inCluding the proFosed sewage tr8atment <br />plant and the U.S. Highlvay 160 prof:osed realigm,ent. A <br />section of the proposed golf course lies within the West Fork <br />100 year floodplain. This is pemdssible onder FeclE'ral <br />floodploin guidelines for developnent. Floods of greater <br />than 100 year recurrence would inundate much of the golf <br />course, although most of the base area apr:ears to be above <br />the estimated 500 year floodplain on the West Fork of the San <br />Juan River. <br /> <br />(2) Alternatives Two and Three <br /> <br />Alternatives Two and Three include the additional effects of <br />the ski area develorment on wetlands on National Forest <br />lands. Since the l'I'etlands have not been mapped, the exact <br />effects are unknown. It is ar,ticip;ted that must of the <br />estimated six acres of wetlands can be avoielecJ o~. these areas <br />are not desirable for c1evelopnent. This is consistent ~lith <br />Forest Service policy in regard to the Wetland Executive <br />Order 11990 which is to avoid, to the extent [.osdble, <br />impacts associated with the destruction, loss or degradation <br />of wetlands. <br /> <br />e.
