The following is a <br /> . tabulated breakdown of costs for each alternative. I had mentioned at the meeting that the <br /> estimated cost for Alternative B had been reduced from the estimate provided in the original <br /> feasibility report as a result ofreceiving preliminary soil boring information. <br /> Alternative R Alternative D Difference <br /> Roadway Improvements 51,201,290,00 51,039,675,00 5161,615.00 <br /> Storm Sewer Improvements $ 297,000.00 $ 245,110,00 5 51,890,00 <br /> Watermain Improvements $ 230,550.00 $ 230,550.00 5 0.00 <br /> Right of Way Acquisition $ 25,000.00 $ 0,00 $ 25,000.00 <br /> Perm, Easement Acquisition S; 28,000 00 $ 78,SOO 00 S 000 <br /> 51,781,840.00 $1,543,835.00 $238,005,00 <br /> Discllssion <br /> Alternative B has a 15% wider footprint than Alternative D. The bituminous area of Alternative <br /> B is approximately 1200 square meters less than Alternative D however the total prepared base <br /> area of Alternative B is approximately 600 square meters greater than Alternative D due to the <br /> larger amount of curb & gutter (due to median islands) included with Alternative B. The net <br /> ",effect of these differences results in approximately $46,400.00 of additional cost for Alternative <br /> B. The larger footprint of Alternative B is reflected in additional common excavation costs and <br /> retaining wall costs (primarily along the Nott Company property) totaling $48,150,00. <br /> Alternative B would also require additional sodding of medians and at a minimum, the <br /> installation of irrigation sleeves for the median areas which is estimated to cost approximately <br /> . $18,400,00, Alternative B traffic control costs are anticipated to be less than Alternative D <br /> however, the TeAAP wellheads would be located within the roadway in Alternative B which <br /> would likely result in additional costs associated with relocation of storm sewer trunk line or <br /> possible modification/relocation costs of the wells themselves, Other minor cost differences <br /> U:\WPOOCS\AIlDENHILIROUNDLAK\COSTCOMP,MEM <br />
