  • APPENDIX A20 CUMULATIVE IMPACTS TECHNICAL MEMORANDUM April 2020 by David Evans and Associates
    APPENDIX A20 CUMULATIVE IMPACTS TECHNICAL MEMORANDUM Environmental Assessment and Section 4(f) Evaluation APPENDIX A20 CUMULATIVE IMPACTS TECHNICAL MEMORANDUM April 2020 By David Evans and Associates INTRODUCTION AND BACKGROUND The I-70 West Vail Pass Auxiliary Lanes project is located in Eagle and Summit Counties, with the eastern terminus just east of the Vail Pass Rest Area and the western terminus in the Town of Vail. The project study limits include eastbound (EB) and westbound (WB) I-70 from mile post (MP) 179.5 to MP 191.5. The project location and approximate study area are shown in Figure 1 . As part of the initial National Environmental Policy Act (NEPA) analysis, a Tier 1 Environmental Impact Statement (EIS) for the I-70 Mountain Corridor (C-470 to Glenwood Springs) was completed in 2011. This EIS, the I-70 Mountain Corridor Programmatic Final Environmental Impact Statement (PEIS), recommended the addition of auxiliary lanes EB and WB on the west side of Vail Pass from MP 180 to MP 190 as part of the Preferred Alternative’s Minimum Program of Improvements. The PEIS also identified the potential for an elevated Advanced Guideway System (AGS) for transit along the I-70 corridor, including the West Vail Pass project corridor. A follow-up AGS Feasibility Study in 2014 analyzed potential alignments and costs for an AGS system and determined there were three feasible alignments for future AGS. While AGS is not part of the West Vail Pass Auxiliary Lanes project, the AGS Feasibility Study was used to ensure the project did not preclude the favored alignment of the three, which would be partially within CDOT right-of-way (ROW).

The company absorbed smaller utilities. It offered power and transmission services to other areas in collaboration with public power agencies and rural electric cooperatives. But tensions with the rural cooperatives were building over territories and customers.

  • The Mount Evans Project by Mo Ewing, Conps Conservation Committee Chairperson
    The Mount Evans Project By Mo Ewing, CoNPS Conservation Committee Chairperson From his collecting visits in the 1950s, to an article he wrote in Aquilegia in August 1991, to the present day, Bill Weber has been a champion for Summit Lake on Mount Evans. In 1965 Bill nominated Summit Lake for designation as a National Natural Landmark because it was considered to be one of the finest examples of alpine tundra in the lower 48 states. For the last couple of years, Bill has urged CoNPS to take over his role as the champion of Mount Evans, expressing a particular concern regarding the presence of non-native mountain goats which the Colorado Department of Wildlife introduced to the area in the 1960s. Last January a group of volunteers met with Bill and Ron Wittmann to consider taking on Mount Evans as a long-term conservation project for our Society. Very quickly we realized that Ron and Bill were the only two people locally who knew much about Mount Evans and Summit Lake. Over the years Bill had brought many internationally renowned botanists to the lake to view its wonders, but otherwise very few people from our area were familiar with the plants and plant communities there. In 1924 the City and County of Denver purchased 160 acres around the lake creating Summit Lake Park and adding it to its Mountain Parks system. So in March some CoNPS volunteers met with Bob Finch, the Director of Natural Resources for Denver Parks and Recreation to discuss how we could work together to preserve Summit Lake.

  • Spanish Peaks Wilderness
    Mt. Bierstadt Field Trip Trip date: 6/17/2006 Ralph Swain, USFS R2 Wilderness Program Manager Observations: 1). The parking lot was nearly full (approximately 35 + vehicles) at 8:00 am on a Saturday morning. I observed better-than-average compliance with the dog on leash regulation. Perhaps this was due to my Forest Service truck being at the entrance to the parking lot and the two green Forest Service trucks (Dan and Tom) in the lot! 2). District Ranger Dan Lovato informed us of the District’s intent to only allow 40 vehicles in the lower parking lot. Additional vehicles will have to drive to the upper parking lot. This was new information for me and I’m currently checking in with Steve Priest of the South Platte Ranger District to learn more about the parking situation at Mt. Bierstadt. 3). I observed users of all types and abilities hiking the 14er. Some runners, 14 parties with dogs (of which 10 were in compliance with the dog-leash regulation), and a new- born baby being carried to the top by mom and dad (that’s a first for me)! Management Issues: 1). Capacity issue: I counted 107 people on the hike, including our group of 14 people. The main issue for Mt. Bierstadt, being a 14er hike in a congressionally designated wilderness, is a social issue of how many people are appropriate? Thinking back to Dr. Cordell’s opening Forum discuss on demographic trends and the growth coming to the west, including front-range Denver, the use on Mt.
