These costs usually are for modification and construc_ <br />tion of the channel, including excavation, backfill and revegetation. In <br />in~tanees where no fo,.."al ehaMel improvements are propo~ed, it 'flay he <br />necessary to protect slopes. '~here slOpe stabi 1 izat ion is required, costs <br />ilssociated with that item are included in the drainaqe improvement cost~. <br />Quanti ties used to prepare the cost estim~te were bd.sed on the ass\II'Tlption <br />that the ChilOnel should be stable. Stabilization is the placement of <br />riprap and/or vegetation to provide an erosion resistant layer. Excavation <br />a~d backfill quantities are estimated based on a cross ~ect ion w'11ch w:Juld <br />safely convey the design flow. <br /> <br />60,OOO.00/ea <br />250,OOO.OO/ea <br /> <br />MIA <br />3n,OOo.OO/ea <br />6.oo/cy <br /> <br />15,000.00Icy <br />2,GOO.00/ea <br />40,OOO.OOlea <br /> <br />In addition to channel improvements, drainaqe improvement costs include the <br />cost of replacinq dams. constructinQ chutes to improve flOOd f1owcondi- <br />tions over dams, structural improvements to dams and diversion structures <br />includfng QuantHy estimates for concrete foundations and other necessary <br />appurtenances. <br /> <br />50.oo/cy <br /> <br />15.00/1f <br />15,OOO.OO/ae <br />15,OOO.OO/ac <br />.3,OOO.OO/ac <br />6,OOO.OO/ac <br />9,OOO.OO/ac <br />21,OOO.OO/mi <br />l.3,OOO.OO/mi <br /> <br />Draina<)etmprovementcosts in Adams County inclUde costs for the st abilil]_ <br />tion of side slopes.
