If the Division is uncertain about the potential vibration effects, however, the Applicant will commit to hiring a third party consultant to conduct a "pre•use" survey of the residence to document existing oaoditions, to measuring vibration during typical operation, and to repairing any vibration dama~ that occurs during the use of the access road. The Hansons do own an easement, which allows access to their property over fire lot at 11061 E. 1 ZO'" Avenue (the Schibli property). The Hansons do not state that this easement is an exclusive easement - erne thatwould allow exclusive use of the Land for the Hanson driveway. This easement is most likely anon-exclusive easement that allows Mr. Schibli to use his land as he desires, as long as thre is no interference with the Hanson's right. The Applicant will confnm that this is anon-exclusive easement and will also commit to maintaining the Hanson's use. As shown by the revised graphic of October l0 (submitted to the Division before the Hansons composed their letter of objection), there will be a stop sign placed at the intersection of the Hanson easement with the mine access road, The mine access road will also not likely require a grade change at this location; but if a grade change is required, the Applicant will contour the Hanson driveway at the intersection, so that the Hansons' driveway continues to be smooth and functional. Typically, an easement like the Hansons' easement cannot be terminated unless the Hansons give it up. or unless the ssrrte person or entity comes to own both properties involved (the Hanson and the Schibli ptoperin). In these circumstances, the Applicant understands that, to complete improvements to 120°' Avenue, Adams Count will need to purchase the Schibli property; and in Fact, Mr. Schibli, who is a member of the 124 Estates Partners, has begun negotiations with the County to sell his lot at 11061 E. 120x" Avenue to the County. With the Hanson easement in place, however, the County will not be able to use the Schibli tot, as it needs to. The County must purchase both properties in order fA obtain the right-of--way needed for planned improvements to 120`h Avenue; and the Applicant expects that the Cou»ty will purchase the Hanson lot or initiate condemnation proceedings to obtain it within the next yeaz. At the southeast corner of the Schibli lot, there is a well that has historically been used for irigation of several nearby properties. Only the Hansons continue to use this well by routing water from it along 120w Avenue and then northward to their property. So that this use of well water is not interrupted, the Applicant will place a 30 foot by 1 S inch culvert in the ditch along 1 ZO`s Avenue, wherethe ditch will cross the proposed access road. Another ditch leads from the same well directly rorthward along the Schibli and Hanson property lines. Although it appears that this ditch has net barn used for a long time, the Applicant will place a culvert at its intersection with theproposed access road, if the Hansons do, in fact, also use this ditch. The ,applicant assumes that the Hanson's septic system, including the leach field, is Located on the Hanson property; which would place all components of the septic system at least 100 feet from the proposed access road, According to the Tri-County Health Department, in a phone conversation of Octalper 23, 2002, no damage to the leach field will occur, unless there is traffic directly on top of it. Regarding potential effects of the access road on livestock, the Applicant believes that domestic animals show a strong tendency to adapt to noise, particularly low level background noise. Cattle and sheep are comntmtly exposed to the noise of machinery of farming and feeding operations. In these circumstances farm animals are already exposed to the noise of traffic from 120'a Avenue, less than 200 feet to the south, and from Highway 85 and the railroad, which are 300 to
