As discussed in Section 3.10, access to the West Route (FDR 60) would be through the City of Steamboat Springs. Because of this, increases in traffic and in the probability of an accident would also occur along the designated city access routes identified in Section 3.10. A final safety impact associated with the proposed project would be an increased chance of a hazardous spill occurring along the West Route. During the construction phase, fuel trucks would be traveIling along the West Route. Approximately 2.7 miles of roads along the West Route are in close proximity to creeks or streams (as defined in Section 3.10). At locations where the West Route is in close proximity to water resources, there would be a high probability that a spill could reach a creek or stream before cleanup could be completed. Road Conditions - Along the West Route, from Dry Lake Campground to Fish Creek Reservoir, there are several sections of roads which have little or no base material. These areas, when wet, can be soft and easily damaged. H a decision to expand Fish Creek Reservoir is made, the City would remove snow from the West Route in the spring and would then transport the equipment required for the proposed expansion to Fish Creek Reservoir. During the mobilization of this heavy equipment, the road surface would likely be wet, and in soft areas where there is little or no base material, damage to the roAd would likely occur. In addition, according to Section 3.10, there Are several culverts along the West Route which have less than one foot of cover. During the mobilization periods, there would be a high probability that these culverts would be damaged. During the construction period of the Proposed Action supply vehicles would be using the West Route daily. By this time, the roads should dry out and should be more conducive to handling an increased load. Furthermore, the weight and size of the supply vehicles would be less than that of the heavy equipment being moved initially. Thus, impacts which would occur to the roads during the construction phase could be of a lesser degree than those impacts which would occur during the mobilization of heavy equipment. However, because of rainfall, the roads would still be wet at times and would continue to be susceptible to damage from the transport of equipment and supplies. In addition, culverts with less than one foot of cover would also be prone to damage. Routt County and the Applicant have developed a memorandum of understanding (MOD) pertaining to site access via County roads. According to the MOU, the Applicant is responsible for the mitigation of all impacts to county roads associated with construction activities. New Road Construction - Under Alternative B, a portion of FDR 310.2 would be inundated. To replace this portion of the road, the City has proposed three road corridor options as shown in Figure 2-5. The preferred road alternative would be constructed using conventional equipment and would be covered with gravel. There would be disturbances to wetlands, however, associated with all three of the road alternatives. These disturbances would be as foIlows: . Road Corridor Option 1 would be constructed through the trees approximately 100 feet from an open meadow. It would disturb approximately 0.69 acres of land, 0.04 acres of which would be wetlands. . Road Corridor Option 2 would be constructed through the middle of an open meadow. It would disturb approximately 0.89 acres of land, 0.37 acres of which would be wetlands. :c::~:~~:::l:;:':':::~~~W":'/":~~;tV.<<~~: :~:l:;'m;::.~~~~~:~:y.-m-;:~::<:=;::;;::.:.ml':<>>.,:,=':::<X-:=:,};~:;':":~.:-0:';':~~:;':(-$:,::;;"'>>;:w.~<::;;,";-.~;:;:x..~ s-pu",ber 1993 Page 4.35
