are not within acceptable limits then the model will be recalibrated using the collected field <br /> information. <br /> 6. Provide the City with a list of field measurements and SCADA monitoring and other data <br /> needed in association with the field fire flow tests for model validation. <br /> Modeling Scenarios <br /> 1. Run the following base simulations in the order listed: <br /> Description Demand Purpose <br /> 2014 CIP Fire Flow 2014 Max Day plus fire flow Evaluate current fire flow conditions <br /> 2014 Peak Hour 2014 Max Day w/diurnal curve Evaluate current peak hr conditions <br /> 2035 Fire Flow 2035 Max Day plus fire flow Evaluate 2035 fire flow conditions <br /> 2035 Peak Hour 2035 Max Day with diurnal curve Evaluate 2035 peak hour conditions <br /> 2035 CIP Fire Flow 2035 Max Day plus fire flow CIP for 2035 fire flow conditions • <br /> 2035 CIP Peak Hour 2035 Max Day with diurnal curve CIP for 2035 peak hour conditions <br /> 2060 Fire Flow 2060 Max Day plus fire flow Evaluate 2060 fire flow conditions <br /> 2060 Peak Hour 2060 Max Day with diurnal curve Evaluate 2060 peak hour conditions <br /> 2. Develop demand scenarios for future wholesale customers in Tulalip and,through <br /> Alderwood,Woodinville, Bothell and North Shore.These wholesale demands will be <br /> included in the appropriate base simulations. <br /> 3. Update any noted changes to the source capacity and storage capacity analysis from the <br /> 2007 CWP. <br /> 4. Perform system analysis for each base simulation to identify system deficiencies. Evaluate <br /> system performance against performance criteria described in WAC 246-290-230. <br /> 5. Identify capital improvements needed to address system deficiencies identified as a result <br /> of the system analysis. <br /> 6. Evaluate the potential for hydropower related to the TL No. 4 and Reservoir 4 system. <br /> 7. Evaluate system storage impacts resulting from transitioning the TL No. 4 and Reservoir 4 <br /> system for potable water use. <br /> 8. Evaluate the need for new Transmission Line 6 and Cross-Tie pipeline. <br /> City Responsibilities <br /> 1. Provide the latest calibrated H2OMAP model. <br /> 2. Provide staff knowledgeable in the operation of the water system for discussions with HDR <br /> personnel. <br /> 3. Identify locations within existing system where pressure or flow problems exist <br /> 4. Provide data from C-factor analysis collected during flushing program, if available. <br /> 5. Assist in the verification of the allocation of demands. <br /> 6. Perform fire flow tests field measurements and SCADA monitoring and other data needed <br /> in association with the field fire flow tests at selected locations, and provide results to HDR <br /> for model validation. <br /> 7. Review and comment on draft Chapter 4 addendum. <br /> Addendum to the 2007 Comprehensive Water Plan January 9,2013 <br /> Exhibit A—Scope of Services Page 7 <br /> 26 <br />
