<br />. <br /> <br />. <br /> <br />. <br /> <br />i3G-: <br /> <br />Supplemental Analysis <br /> <br />BENEFIT-COST RATIOS <br /> <br />"(3) Benefit-cost ratios calculated by using total tangible benefits <br />and total tangible costs for 100 years, and for 50 years, except where <br />the economic life of the major facility is less." <br /> <br />Total tangible benefits for a 100-year period of analysis are <br />identical to total benefits used in the Reclamation procedure in <br />Part IX, "Economic and Financial Analyses." Tangible net benefits <br />for the Senate Resolution 148 analysis are summarized in table 35. <br /> <br />Table 35--Tangible net annual benefits, Senate Resolution 148 <br /> <br />Type <br /> <br />50-Year <br />Period <br /> <br />100-Year <br />Period <br /> <br />Irrigation <br />Direct <br />Indirect and public <br />OM&R savings <br />Flood control <br />Fish and Wildlife enhancement <br />National <br />Local <br />Recreation <br />Initial development <br />Discounted future development <br />Total <br /> <br />:I> 1,631,500 <br />(1,394,000 ) <br />( 221,500) <br />( 16,000) <br />961,000 <br />292,700 <br />( 51,000) <br />( 241,700) <br />790,000 <br />( 340,000) <br />( 450,000) <br />~ 3,675,200 <br /> <br />:I> 1,631,500 <br />(1,394,000) <br />( 221,500) <br />( 16,000) <br />961,000 <br />292,700 <br />( 51,000) <br />( 241,700) <br />692,000 <br />( 340,000) <br />( 352,000) <br />~ 3,577,200 <br /> <br />Benefit-cost ratios are 1.57 for a 100-year period of analysis and <br />1.28 for a 50-year period of analysis. The derivation of these ratios <br />is shown in table 36. This analysis differs from the Reclamation <br />analysis in Part I.lI. only in that no deduction is made for the cost of <br />preauthorization investigations. No credit is taken for salvage value, <br />although the principal features would have useful lives in excess of <br />100 years. <br /> <br />110 <br />
