. . CDM Camp Dresser & McKee lnc. T. Crumpton (9/5/95) Page Number 7 present location on the west side of the creek behind the Stefen property. This has the advantage of not disturbing the orchard or impacting the highway and is also well above the flood high water level. Although construction could be accomplished with a shallow bury or partially exposed installation, major concerns include temporary water supply, protection of the new pipe from rock falls, and maintaining practical maintenance access. Traversing the Cole property resulted in some general disagreement among the group. CDOT favors an alignment which follows the existing or one which keeps the pipe on the west side of the creek, installing a permanent bridge if necessary. Unfortunately, this would involve two creek crossings and\or an alignment on the high side of the west slope (likely leaving a noticeable scar with poor access). The project team, Ute Water, and the ACOE prefer an alignment which crosses the highway twice in a relatively short length and then either parallels the highway around the Cole property or traverses a straight alignment behind the property. CDOT requested more study be done prior to finalizing the alignment. Approaching the Rainey property from the lower canyon; there do not appear to be any optimal alignments. All individuals agree that a creek crossing will be required to gain access to the property when leaving the narrow portion of the canyon. This is one area where the creek moves frequently and high water flows over the pipeline. One option which looks attractive below highpoint is to utilize the old stage road located on the west side of the creek. This would avoid two river crossings and potential impacts to wetlands and bird habitat on the east. side. Initial indications are that installation of a pipeline in the stage road would be acceptable as long as the appropriate documentation is completed (note subsequent project team on site investigation of the stage road indicates this option is not viable for the size pipeline being considered). Adjacent to 1-70, CDOT's official position is that a minimum of 30 feet of clearance is required between a utility and the white strip on the edge of the shoulder. An alignment adjacent to the interstate, but encroaching on the base of the hillside would violate this criteria in many places. CDOT would prefer the new pipeline be placed at the location of the existing. One option is to construct a temporary service line at the foot of the hill to maintain service during construction and cut the existing shelf down (widening the shelf while removing the existing pipeline). This would allow for replacement with the new line without affecting service. There are other options to consider here also, but restricting encroachment and access to and from the interstate are primary issues with CDOT (which must get approval from the Federal
