CWCB construction loan. Maximum loan amount would be $600,000 at 4% per year for 40 <br />years. <br />2. Department of Local Affairs grant. <br />3. Water and Power Authority loan. <br />4. City Funds. <br /> <br />VI. <br /> <br />CONCLUSIONS AND RECOMMENDATIONS <br /> <br />The models used in the PIS, which did not include the City's diversion weir, do not appear to <br />recognize the existing levee along the south banle When the existing levee is considered, the 100- <br />year water surface elevation modeled without the diversion weir is 5356.2, 1.9-feet higher than shown <br />in the FIS. When the existing weir is modeled, along with a levee on the south bank to contain the <br />100-year flow, the water surface elevation is 5359.3 under this scenario flow ov,ertops the railroad <br />embankment, which results in property north of the railroad, which is currently outside the floodplain, <br />to be located in the floodplain. <br /> <br />At the City's request, the Scope of Services was modified to evaluate improvements that would <br />provide the same level of protection that existed before the diversion weir was constructed. The flow <br />rate for that scenario was determined to be 11,350 cfs, corresponding to an 18-year event. WRC also <br />evaluated the flow that could be conveyed if the depth of flow were increased by 0.50 and 1.0 feet. <br />Cost estimates were prepared for each of the design flows. <br /> <br />Based upon the analysis presented herein, we recommend that levee improvements be constructed to <br />_______ _.__ _ ___ _ _". ____. __ _ _ _ o. _ _n. __ __. _ <br />contain a flow rate of 11 ,350 cfs. This will provide a level of protection equal to that provided <br />before the diversion weir was constructed. Flows in excess of 11,350 cfs would overtop the proposed <br />levee, which would be designed to allow for overtopping. The estimated cost of this alternative is <br />$399,716. Because the levee would not provide protection from the 100-year event, it would not be <br />recognized by FEMA. Therefore the 100-year flood plain would not change. <br /> <br />8 <br />
