<br />Th" r1..t,il..tl enst estimates for both plans are presented in Appendix E. The
<br />original estimated costs presented in Appendix E are valid: however, the cost appor-
<br />tionment breakout of several cost items has been revised. The revised cost apportion~
<br />mcnt is correctly shown in the Cost Apportionment :;cetion of Chapter 7 (tables 7-1
<br />and 7-2.)

<br />
<br />The construction of the plans would result in reduced flooding on Dry Creek,
<br />primarily between Larimer and Weld Canal and East Vine Drive. These benefits are
<br />quantified below. Those potential project benefits which are not quantified include a
<br />reduction in flood insurnnecadministration costs, recreation hcnefits, land devclopment
<br />henefits, and agricultural benefits,

<br />fLOOD DA:\IAGE REIlUCTlON
<br />Under existing cnnditions, the cAD for Dry Creek is $6Sl\,700. With the tOO-year
<br />plan, the residual damages would be $214,500, ora reduction of67 percent. Average
<br />annual ocncfilS would be $444,200 annually,
<br />
<br />Wilh the30-yearplan, the residual damages would be $288,500, ora roo\lctlonof
