• Yield Constrained by Hydropower Operations—The yield when bound by factors r, <br /> limiting unconstrained yield, transmission limitations upstream of Chaplain <br /> Reservoir, and hydropower operations. Additionally, this scenario will limit <br /> drawdown to an elevation of 1,380 feet. <br /> • Yield Constrained by Water Rights —This is the yield bound by those factors <br /> limiting its unconstrained yield, transmission limitations upstream of Chaplain <br /> Reservoir, and hydropower operations. <br /> The model will only be run for "typical" operation not for unusual backflow/water <br /> rerouting conditions. These 15 simulations will be compared to the results described <br /> in the 2000 Yield Analysis. A technical memorandum will be developed by the HDR <br /> Project Team describing the simulation results and comparison with the 2000 Yield <br /> Analysis. Note: This approach does not include updating the 2000 Yield Analysis by <br /> incorporating additional historical record now available. <br /> 6. The HDR Project Team, City staff, and Dr. Palmer will conduct a half-day workshop <br /> discussing the findings for City of Everett. <br /> Revised Climate Change Approach — HDR/U of W Budget Impacts <br /> Recommended additional budget: Original scope was written for running 3 climate <br /> scenarios given 3 supply conditions (9 simulations). The revised approach will result in <br /> 15 simulations. This increase effort will impact estimated budgets for both HDR and the <br /> UofW. <br /> • Amie Hanson —40 hours. This includes additional simulations, additional analysis, <br /> and additional time presenting results. Note: This assumes that no changes need to <br /> be made to the model to be updated. <br /> • Allison MacEwan —8 hours for additional input review. <br /> • Purchase Power Sim Studio Standard Software — approximately $1,100 with tax and <br /> shipping. <br /> Labor (including tech charge): <br /> 40 hours A.
