North Eagleview Oroinoge Concept Phase <br />SUMMARY <br />The table below smimortius coat differences and attempts to rmk each alternatds rebfive impact on the erdsting <br />Eagkvrew Pad, ar the bndswpe, and an the wildlife habitat that edsis presently m the #3 Ditch bodes and m the <br />cettanwood gets adjacent to the Pad. <br />Note that the costs shown for the'Pad" concept are rat estimated total project costs, but only the cost of the <br />differences betwxn the two ahuantes of ihe'Pad' mrKept. Since the difference Ls so great, are did rwt <br />consider it feasible to purge further Alternate 1- Cansfevef Regiaal Pad. The costs listed far each akermte <br />fader Caicept'Flor are told estimated project cost - oonatnxtian, rwrrtmgvxy, engineering and lad purchase - <br />ard inchde the cosT of building the brge charnel to the Gravel P-it pad. <br />Canporlaai Impact m <br />g ~ <br />s <br />• M <br />Concept Alternate Cost Lad ~ o ~ <br />(~) <br />POND Rcgian/Datenlian Pond <br />1.
