, <br /> Construction Staging Areas <br /> A construction staging area for the Segment 3 pipeline alignment will be provided at the <br /> northeast corner near the intersection of Jewell Avenue and Monaghan Road.The site was <br /> selected for construction staging because it is not farmed and has paved road access <br /> midway along the alignment. <br /> Existing Land Use and Future Development <br /> Land use along the 8.8-mile Segment 3 corridor from the PS-3 site to the ARWPF is mostly <br /> undeveloped with some adjacent dry land agriculture. The Monaghan Road alignment <br /> crosses four proposed subdivisions (Trails at First Creek,Sand Creek Ranch,Eastern Hills, <br /> and Coal Creek Reserve),which have been annexed into the City and which have submitted <br /> preliminary development plans.The annexation agreements require the developer to <br /> dedicate ROW prior to development,eliminating the need for easement acquisition for <br /> construction of Segment 3 along part of the Monaghan alignment. <br /> Development along the Monaghan Road corridor is not expected for another four to eight <br /> years and is not expected to affect construction of the pipeline. <br /> Special Crossings <br /> In addition to the USACE jurisdictional crossing at Coal Creek,two other special crossings <br /> are included in Segment 3.Monaghan Road and Quincy Avenue will be constructed as <br /> trenchless crossings to maintain traffic safety during construction.Local geotechnical <br /> conditions indicate that these crossings are technically feasible. <br /> Conveyance System Cost Estimates <br /> Construction cost estimates prepared at the 90%design level,and design costs encumbered <br /> by Aurora Water for the conveyance system, are listed by bid package in Table 1 below. <br /> TABLE 1.Construction Cost Estimates and Encumbered Design Costs for PWP Pipelines and Pump Stations <br /> Construction Cost Encumbered <br /> Design Cost <br /> Original After Value <br /> Estimate Engineering <br /> Bid Package E—Pumping Stations 1,2 and 3 $87,800,000 $57,800,000 $4,181,604 <br /> Bid Package G—Conveyance Pipeline Segment 1 $115,900,000 $75,900,000 $2,640,734 <br /> Bid Package H—Conveyance Pipeline Segment 2 $82,300,000 $62,300,000 $2,545,093 <br /> Bid Package I—Conveyance Pipeline Segment 3 $51,300,000 $41,300,000 $1,726,837 <br /> Total $337,300,000 $237,300,000 $12,502,306 <br /> Aurora Water and the Program Management team continue to value engineer these <br /> elements of the PWP,to determine if revisions to design criteria could further reduce the <br /> cost of the pipeline and pumping stations without compromising the long-term <br /> functionality and reliability of the system.Depending on which if any additional value <br /> 22 <br />
