NORWEST <br /> COR PORAT ION <br /> To: Colorado Division of Reclamation, Mining, and Safety Ref# 591-6 <br /> CC: Jerald Schnabel,Transit Mix Date: October 3, 2017 <br /> From: Paul Kos <br /> Subject: Engineering Evaluation of Highway 115 <br /> Introduction <br /> Highway 115 is an existing structure located within 200 feet of the proposed Hitch Rack Ranch Quarry <br /> permit boundary. The location is shown on Figure 1. This engineering evaluation discusses the structure <br /> location and components before evaluating potential impacts quarry development may have on the <br /> structure and presenting how the quarry has been designed so there are no adverse impacts to Highway <br /> 115. <br /> Structure Description <br /> Highway 115 is located within 200 feet of the proposed Hitch Rack Ranch Quarry permit boundary at the <br /> intersection with the proposed access road. This is at the easternmost extent of the permit area and <br /> located away from mining areas. At this location, Highway 115 is a two-lane, paved road. The <br /> southbound lane has an acceleration/passing lane that ends at the approximate location of the Hitch <br /> Rack Ranch Quarry's proposed access road. Work activities in and along Highway 115 will only occur <br /> during construction of the access road and acceleration and deceleration lanes. <br /> Potential Impacts and Mitigation <br /> Potential Problem: Construction of the access road could damage Highway 115. <br /> Solution: Development of the quarry will require construction of acceleration and deceleration lanes on <br /> both the north and southbound lanes of Highway 115. The road widening will result in improved lines of <br /> sight at the intersection, which is also at the crest of a hill. All construction will occur within the <br /> Highway 115 right-of-way. The lanes will be designed following Colorado Department of Transportation <br /> (CDOT)guidelines and regulations and will be permitted with CDOT. Therefore, Highway 115 will not be <br /> adversely impacted by construction of the quarry access road. <br /> Hitch Rack Ranch Quarry Amendment Exhibit T <br /> October 3,2017 <br /> S-3 <br />
